Title: Auto vehicle capable of processing waste matter

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an auto vehicle capable of processing waste matter configured to complete the processing to recycle collected waste matter up to a predetermined stage while it is running. 
     2. Description of the Related Art 
     Conventionally, waste matter, such as containers represented by a pet bottle disposed from homes and various sales stores, such as a convenience store and a supermarket store, is first collected by a waste matter collection vehicle and discharged at an intermediate processing station. The waste matter is subjected to compression processing and volume reduction processing, such as chipping. After the application of the volume reduction processing, the waste matter is generally transported from the intermediate processing station to the recycle factory, which is the final disposal station, and final disposal for recycle is applied to the volume-reduced waste matter. 
     The recycle system of container waste matter as described above, however, has a disadvantage that an investment of a large amount of money is required to construct the intermediate station. In order to overcome this disadvantage, Patent Documents 1 through 3 propose to apply the volume reduction processing to container waste matter collected by a waste matter collection vehicle, which is an auto vehicle, on the vehicle. 
     Patent Document 1 proposes a configuration to provide compressing means for applying compression processing to pet bottles and a baling means for baling the pet bottles compressed by the compressing means to the deck of the waste matter collection vehicle. The pet bottles after the compression processing are then delivered from the waste matter collection vehicle to the recycle factory in the form of bales. 
     On the contrary, Patent Documents 2 and 3 propose a configuration to feed pet bottles one by one to a shredder having rotary blades and provided at the back of the deck of the waste matter collection vehicle, so that the pet bottles are cut into chips after the labels are removed. The resulting chips are collected into a collection box mounted on the deck and the collection box is delivered to the recycle factory when it becomes full. 
     Hence, by using the waste matter collection vehicles described in Patent Documents 1 through 3 as a mobile factory, not only is it possible to provide extraordinary high mobility to the mobile factory, but it is also possible to eliminate the need to construct the intermediate processing station for applying the volume reduction processing to pet bottles. It thus becomes possible to obtain an extremely high degree of economic effect in terms of construction fees and constant expenses. 
     Patent Document 1: JP-A-10-291603 
     Patent Document 2: JP-A-10-249857 
     Patent Document 3: JP-A-10-250802 
     Incidentally, because the waste matter collection vehicle described in Patent Document 1 is merely to reduce the volume by compressing pet bottles, the pet bottles have to be cut into chips in the final factory in some cases. This proposal therefore has a problem that it is inadequate as the intermediate processing for container waste matter. 
     Also, with the waste matter collection vehicle described in Patent Documents 2 and 3, the worker has to manually insert pet bottles into the shredder provided at the rearmost of the deck one by one for subjecting pet bottles to shredding processing. These proposals therefore have a problem that the workability is poor. 
     SUMMARY OF THE INVENTION 
     The invention has an object to provide an auto vehicle which can process waste matter with ease. 
     According to an aspect of the invention, an auto vehicle capable of processing waste matter is adapted for applying a predetermined processing to waste matter made of a recyclable material while collecting the waste matter, and comprises an aligning portion configured to align loaded waste matter, a processing portion configured to apply chipping to the waste matter aligned by the aligning portion, and a chip storing portion configured to store chips formed by the processing portion.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION 
       FIG. 1  is a schematic side view of a factory truck according to a first embodiment of the invention and  FIG. 2  is a schematic plan view. In  FIG. 1  and  FIG. 2 , the X-X direction is defined as the right-left direction and the Y-Y direction is defined as the front-rear direction. In particular, the −X direction is defined as leftward, the +X direction is defined as rightward, the −Y direction is defined as frontward, and the +Y direction is defined as rearward. 
     A factory truck (auto vehicle capable of processing waste matter)  10  of the first embodiment is to apply chipping to a subject, herein, a PET (polyethylene terephthalate) bottle P, which is a type of bottles made of synthetic resin as waste matter to be collected. 
     As is shown in  FIG. 1  and  FIG. 2 , the factory truck  10  includes a cabin portion  11  having an engine, a driver&#39;s seat, and so forth, and a deck  12  connected to the rear portion of the cabin portion  11 . To the deck  12  are provided a loading portion  20  that stores empty pet bottles P loaded therein, an aligning portion  30  that aligns pet bottles P pulled out from the loading portion  20 , a processing portion  40  that successively applies chipping to pet bottles P aligned serially by the aligning portion  30 , and a chip storing portion  80  that stores chips P 3  obtained by the processing portion  40 . 
     The loading portion  20 , the aligning portion  30 , and the chip storing portion  80  are covered with a covering body  13  in the shape of a square prism when viewed as a whole from the outer appearance. A soundproof material  131  made, for example, of a foaming synthetic resin, is applied to the covering body  13  on the inner surface side. It is therefore possible to prevent noises generated inside the covering body  13  from leaking to the outside. 
     A loading opening  132  through which pet bottles P are loaded and a openable and closable rear door  133  capable of closing the loading opening  132  are provided on the rear surface of the covering body  13  almost entirely. The rear door  133  is normally closed and it is opened as is shown in  FIG. 1  when pet bottles P are loaded into the loading portion  20 . 
     The loading portion  20  includes a loading hopper  21  installed at the rear end portion of the deck  12  and a belt conveyor  22  attached to the loading hopper  21 . As is shown in  FIG. 2 , the loading hopper  21  is of a rectangular shape when viewed in a plane. The top-bottom dimension is set to about ½ of the top-bottom dimension of the covering body  13 , and as is shown in  FIG. 1 , the front plate, which is one of components of the loading hopper  21 , is an inclined plate  211  inclined to point upward (in this embodiment, inclined by about 60°). 
     The belt conveyor  22  includes a drive roller  221  provided in such a manner that the shaft center extends in the right-left direction immediately behind the inclined plate  211  inside the loading hopper  21 , a driven roller  222  provided oppositely to the drive roller  221  at a position above and slightly ahead of the drive roller  221  so as not to interfere with the top plate of the covering body  13 , and an endless belt  223  stretched between these drive roller  221  and the driven roller  222 . 
     The drive roller  221  is configured to be driven to rotate in a counterclockwise direction by the driving of a first drive motor  224  ( FIG. 2 ). Accordingly, the drive roller  221  is driven when the first drive motor  224  is driven, which causes the endless belt  223  stretched between the drive roller  221  and the driven roller  222  to circulate between the both rollers  221  and  222  in a counterclockwise direction. 
     A plurality of hooking protrusion pieces  223   a  are provided on the endless belt  223  lengthwise on the surface side at regular pitches. Accordingly, while the endless belt  223  is circulating in a counterclockwise direction, pet bottles P stored inside the loading hopper  21  are transported upward while being hooked by the hooking protrusion pieces  223   a  and fed into the aligning portion  30  when the endless belt  223  makes a turn at the position of the driven roller  222 . 
     The aligning portion  30  is to serially align pet bottles P fed therein from the loading hopper  21  with circulations of the endless belt  223  to facilitate the processing thereafter. Hereinafter, the aligning portion  30  will be described on the basis of  FIG. 3  and with reference to  FIG. 1  and  FIG. 2  when necessary.  FIG. 3  is a perspective view showing one example of the aligning portion  30 . The indication of direction using X and Y in  FIG. 3  is the same as in  FIG. 2  (X is the right-left direction (−X: leftward, +X: rightward), and Y is the front-rear direction (−Y: frontward, +Y: rearward)). 
     As is shown in  FIG. 3 , the aligning portion  30  includes an aligning hopper  31  that receives pet bottles P from the loading portion  20 , a plurality of aligning rollers  32  that are laid at the bottom portion of the aligning hopper  31  so as to extend in the front-rear direction, a second drive motor  33  that rotates a plurality of the aligning rollers  32  simultaneously in the same direction about the shaft center, and a drive force transmission mechanism  34  that transmits a drive force of the second drive motor  33  to the respective aligning rollers  32 . 
     The aligning hopper  31  includes a pair of side plates  311  paired in the right-left direction, a front plate  312  provided to bridge between the front edge portions of a pair of these side plates  311 , a rear plate  313  provided to bridge between the rear edge portions of the respective side plates  311 , and a pair of guide plates  314  paired in the right-left direction and provided to extend frontward from almost the center positions in the front-rear direction of the respective side plates  311  while gradually coming into close proximity to each other. 
     The rear plate  313  is set in such a manner that the top edge portion becomes slightly lower than the top edge portions of the side plates  311 . The top end portion of the endless belt  223  is fit into this potion set lower. It is therefore configured in such a manner that pet bottles P carried by the endless belt  223  are delivered to the aligning hopper  31  in a reliable manner. 
     The front plate  312  is set in such a manner that the top edge portion is flush with the top edge portions of the side plates  311 , whereas the bottom edge portion is spaced apart from the top surfaces of the aligning rollers  32  sufficiently for pet bottles P to pass through. The guide plates  314  are formed in such a manner that the top edge portions are flush with the top edge portions of the side plates  311  and the bottom edge portions almost come into sliding contact with the top edge portions of the aligning rollers  32 . The front end edges of the respective guide plates  314  are spaced apart by a distance large enough for a pet bottle P oriented in the front-rear direction to pass through. Accordingly, a bottle passing opening  315  that allows only one pet bottle P oriented in the front-rear direction to pass through is formed at the front end position between the respective guide plates  314 . 
     A plurality of the aligning rollers  32  are provided side by side between a pair of the side plates  311  and inclined to point downward to the front. Each aligning roller  32  has a roller shaft  321  penetrating through the inside and concentric with the center position in an integrally rotatable manner. Each roller shaft  321  penetrates through the aligning roller  32  in a state where it comes into sliding contact with an unillustrated frame at the front and the rear ends. This configuration allows each aligning roller  32  to integrally rotate about the roller shaft  321 . 
     The second drive motor  33  is installed in a horizontally oriented posture to extend in the front-rear direction at a position at the front end of the aligning hopper  31  slightly outward from one side portion in the right-left direction. A drive force thereof is transmitted to the respective aligning rollers  32  via the drive force transmission mechanism  34 . 
     The drive force transmission mechanism  34  includes a drive sprocket  341  fit outwardly to the drive shaft of the second drive motor  33  concentrically in an integrally rotatable manner, a plurality of driven sprockets  342  fit outwardly to the corresponding roller shafts  321  concentrically in an integrally rotatable manner, and a chain  343  put around the respective driven sprockets  342  and the drive sprocket  341 . 
     According to the drive force transmission mechanism  34  as above, by driving the second drive motor  33 , the drive force is transmitted to the respective driven sprockets  342  via the drive sprocket  341  and the chain  343 . All the aligning rollers  32  thus rotate simultaneously in the same direction about their own roller shafts  321 . 
     Pet bottles P transported into the aligning portion  30  from the loading portion  20  with circulations of the endless belt  223  by the driving of the first drive motor  224  are therefore guided by the rotations of the respective aligning rollers  32  in the same direction and thereby rotated in the opposite direction. The pet bottles P then slide down the aligning rollers  32  inclined to point downward to the front while the postures are being set to orient in the front-rear direction, and gathered in the center portion in the right-left direction by a pair of the guide plates  314 . The pet bottles P are thus fed to the processing portion  40  one by one by passing through the bottle passing opening  315 . 
     Referring to  FIG. 1  and  FIG. 2  again, the processing portion  40  includes a sorting portion  50  that sorts each pet bottle P fed from the aligning portion  30  to a bottle main body P 1  and an accessory P 2 , and a shredder portion  60  that applies shredding processing to the bottle main body P 1  sorted out by the sorting portion  50  to shred it into chips P 3 . The accessory P 2  includes a mouth ring and a cap attached to the bottle main body P 1 , and further includes an annular label wrapped on the base of the bottle and so forth. 
     In general, these accessories P 2  are often made of a synthetic resin material different from the bottle main bodies P 1  made of PET (polyethylene terephthalate). When such a material is mixed into the chips P 3  made of PET, it turns into an impurity during the recycle processing of the chip P 3  and raises a problem in the recycle processing. The accessories P 2  are sorted out by the sorting portion  50  in order to forestall such a problem. 
     Hereinafter, the sorting portion  50  will be described on the basis of  FIG. 4  and with reference to  FIG. 1  through  FIG. 3  when necessary.  FIG. 4  is a perspective view showing the sorting portion  50 . The indication of direction in  FIG. 4  using X and Y is the same as in  FIG. 3  (X is the right-left direction (−X: leftward, +X: rightward), and Y is the front-rear direction (−Y: frontward, +Y: rearward)). As is shown in  FIG. 4 , the sorting portion  50  includes a axial cutter device  51  that longitudinally cuts pet bottles P, and a sieve device (separation device)  58  that sifts broken pieces of the bottle main bodies P 1  and broken pieces of the accessories P 2  formed when pet bottles P are longitudinal cut by the axial cutter device  51 . 
     The axial cutter device  51  includes a right-left pair of rail members  52  that receives a pet bottle P and moves it downstream by sliding contact, a front-rear pair of compression rollers  53  disposed oppositely to the top surfaces of a pair of these rail members  52  to compress the pet bottle P, a band saw  54  provided between a pair of the compression rollers  53  and also between a pair of the rail members  52  to extend in the top-bottom direction, and a rotation mechanism  55  that rotates a pair of the compression rollers  53 . 
     Of all the aligning rollers  32 , a pair of the rail members  52  is provided correspondingly to the two aligning rollers  32  at the center portion in the right-left direction, and a spaced distance between the rail members  52  is set to be shorter than the diameter dimension of the pet bottle P. Each rail member  52  is provided in such a manner that the top surface extends horizontally, and an inclination portion  521  inclined by the same inclination angle of the aligning rollers  32  is provided on the under surface of the rear end portion. The rail member  52  is therefore tapered off rearward. 
     The respective inclination portions  521  oppose the peripheral top surfaces of the corresponding aligning rollers  32  provided adjacently via a slight clearing. Accordingly, a pet bottle P sliding down while rotating about the center of the bottle between the aligning rollers  32  provided adjacently is scooped up by a pair of the rail members  52 . 
     A pair of the compression rollers  53  applies compression processing to the pet bottle P scooped up by the rail members  52  in order to facilitate breaking processing and shredding processing on the pet bottle P thereafter. Each compression roller  53  includes a roller shaft  531  and a metal roller main body fit outwardly to the roller shaft  531  concentrically in an integrally rotatable manner. A distance between the respective compression rollers  53  is set to be long enough to accommodate the band saw  54 . 
     A distance between the lower peripheral surface of each compression roller  53  and the top surfaces of the rail members  52  is set to be slightly larger than the thickness dimension of the pet bottle P when the base thereof is flatten out so as to leave a clearing. 
     The rotation mechanism  55  is formed of a third drive motor  56  that drives one roller shaft  531  (the rear roller shaft  531  in the case of  FIG. 4 ) to rotate, and a gear mechanism  57  that transmits the drive rotation of one roller shaft  531  to the driven rotation of the other roller shaft  531 . The drive shaft  561  of the third drive motor  56  is coupled to the rear roller shaft  531  concentrically in an integrally rotatable manner. 
     The gear mechanism  57  includes a drive gear  571  fit outwardly to the rear roller shaft  531  concentrically in an integrally rotatable manner, a driven gear  572  fit outwardly to the front roller shaft  531  concentrically in an integrally rotatable manner, and an idle gear  573  interposed between the driven gear  572  and the drive gear  571  so as to mesh with the both gears. Accordingly, when the drive shaft  561  is rotated in a clockwise direction by the driving of the third drive motor  56 , the rotation is transmitted to the driven gear  572  via the drive gear  571  and the idle gear  573 . The front and rear compression rollers  53  thus rotate in a clockwise direction about their own roller shafts  531 . 
     The pet bottle P sliding down while rotating between the aligning rollers  32  provided adjacently is introduced into a space between a pair of the rotating compression rollers  53  and a pair of the rail members  52  and subjected to compression processing. 
     The band saw  54  is to longitudinally cut the pet bottle P lengthwise as it is forcedly moved frontward while it is subjected to compression processing by the compression roller  53  on the upstream side (the rearward side). The band saw  54  is attached in a space defined between a pair of the compression rollers  53  and between a pair of the rail members  52  of a rectangular shape when viewed in a plane in such a manner so as to extend in the top-bottom direction with the saw teeth  541  facing rearward. The band saw  54  is supported on an unillustrated frame in an up-and-down movable manner and an up and down movement providing mechanism  542  is provided on one end side. 
     Each pet bottle P introduced from the aligning rollers  32  into the compression roller  53  on the upstream side travels on the rail members  52  while being compressed by this compression roller  53 , and subsequently, the pet bottle P together with the accessory P 2  is longitudinally cut by the saw teeth  541  of the band saw  54  being moved up and down in a vibrating manner by the driving of the up and down movement providing mechanism  542  in succession. The pet bottle P cut into two pieces after the longitudinally cutting processing is further subjected to compression processing by the compression roller  53  on the downstream side, after which it is sent toward the sieve device (separation device)  58  in a state where the bottle main body P 1  and the accessory P 2  are broken into pieces. 
     The sieve device  58  is to separate the longitudinally cut pieces of the bottle main bodies P 1  and the accessories P 2  in a compressed state obtained by the axial cutter device  51  into the bottle main bodies P 1  and the accessories P 2 , and provided with an inclination pointing downward to the front. The sieve device  58  includes a frame body  581  of a rectangular shape, a metal net  582  stretched across the frame body  581 , and a vibration mechanism  583  that gives vibrations to the metal net  582 . 
     Supporting shafts  581   a  are provided on the front end portion of the frame body  581  so as to protrude oppositely in the right-left direction. These supporting shafts  581   a  are supported on an unillustrated frame in a rotatable manner about the shaft center. This configuration allows the frame body  581  to oscillate about the supporting shafts  581   a.    
     The dimension of the mesh of the metal net  582  is set in such a manner that the metal net  582  can sift out the accessories P 2 , such as mouth rings and caps, as the passing matter that is allowed to pass through the mesh and the broken bottle main bodies P 1  as the remaining matter. 
     The vibration mechanism  583  includes a cam shaft  584  that transversely crosses the under surface of the frame body  581  in the right-left direction on the rear side in a sliding contact state, a pair of eccentric cams  585  paired in the right-left direction that is fit outwardly to the cam shaft  584  in an integrally rotatable manner, and a fourth drive motor  586  that rotates the cam shaft  584  about the shaft center. The drive shaft  586   a  of the fourth drive motor  586  is coupled to the cam shaft  584  concentrically in an integrally rotatable manner. 
     The respective eccentric cams  585  are fixed to the cam shaft  584  in the same phase and the respective peripheral surfaces abut on the frame body  581  on the back surface side of a right-left pair of longitudinal beams extending in the front-rear direction. Accordingly, when the cam shaft  584  is rotated about the shaft center by the driving of the fourth driving motor  586 , the respective eccentric cams  585  rotate eccentrically. These eccentric rotations cause the metal net  582  to rotate about the supporting shafts  581   a  forward and backward in a vibrating manner. The broken accessories P 2  fed to the sieve device  58  are sifted out in a reliable manner by passing through the mesh of the metal net  582  by the vibrations of the metal net  582 . 
     Meanwhile, an accessory storing portion  59  ( FIG. 1 ) to store the accessories P 2 , such as mouth rings and caps, sifted out by the sieve device  58  as the passing matter is provided at a position below the aligning portion  30 . A flexible container bag  591  for accessory collection is attached to the accessory storing portion  59  in a state where the top surface is fully opened. The accessories P 2  sifted out by the sieve device  58  are collected into the flexible container bag  591 . When the flexible container bag  591  becomes full, it is unloaded from the accessory storing portion  59  with the opening in the top surface closed. 
     In this embodiment, a suction device  70  as is shown in  FIG. 1 ,  FIG. 2 ,  FIG. 4 , and  FIG. 5  to collect light accessories P 2 ′, such as labels separated in the sieve device  58 , is provided. The suction portion  70  includes suction hoods  71  provided on the frame body  581  of the sieve device  58  on the both side portions in the right-left direction, suction ducts  72  connected to the respective suction hoods  71 , a collection portion  73  connected to the downstream ends of the suction ducts  72  to collect the light accessories P 2 ′, and a suction blower  74  connected to the downstream end of the collection portion  73 . 
     The collection portion  73  has a casing  731  in the shape of a rectangular prism that is hollow inside, and a bag filter  732  attached to the casing  731  in a reattachable manner. 
     According to the suction device  70 , a sheet of light accessory P 2 ′ wrapped on the bottle main body P 1  is separated into pieces from the bottle main body P 1  as the pet bottle P is longitudinally cut by the axial cutter device  51 . Pieces of a sheet of light accessory P 2 ′ are sucked into the suction hoods  71  by an air flow developed by the driving of the induction blower  74  when these pieces move onto the metal net  582  of the sieve device  58  and trapped and collected in the bag filter  732  via the suction ducts  72 . 
     Referring to  FIG. 1  and  FIG. 2  again, the shredder portion  60  is to further apply shredding processing to the longitudinally cut pieces of the bottle main bodies P 1  fed from the sieve device  58  as the remaining matter to form the chips P 3 , and it is provided directly downstream of the sieve device  58 . Hereinafter, the shredder portion  60  will be described in detail on the basis of  FIG. 5  and with reference to  FIG. 1  through  FIG. 4  when necessary.  FIG. 5  is a perspective view showing the shredder portion  60 . The indication of direction using X and Y in  FIG. 5  is the same as in  FIG. 2  (X is the right-left direction (−X: leftward, +X: rightward), and Y is the front-rear direction (−Y: frontward, +Y: rearward)). 
     As is shown in  FIG. 5 , the shredder portion  60  includes a top-bottom pair of shredder gears  61  meshed with each other, a fifth drive motor  62  to rotate a pair of these shredder gears  61 , and a speed reduction gear  63  interposed between the fifth drive motor  62  and the shredder gears  61 . 
     Each shredder gear  61  is formed of a gear shaft  611  and a gear main body  612  fit outwardly to the gear shaft  611  concentrically in an integrally rotatable manner. The gear main body  612  is provided with a plurality of gear teeth  613  at regular pitches in the circumferential direction. The tip end of each gear tooth  613  is formed sharp. The pet bottle main body P 1  fed to the mesh position of the upper and lower shredder gears  61  after the breaking processing is shredded by the respective gear teeth  613  at the mesh position of the gear teeth  613 . The chips P 3  are thus formed. 
     The fifth drive motor  62  is installed in the vicinity of one shredder gear  61  (the upper shredder gear  61  in the case shown in  FIG. 5 ) in a horizontally oriented posture so that the drive shaft  621  extends in the right-left direction. The speed reduction gear  63  is formed of a small diameter gear  631  fit outwardly to the drive shaft  621  concentrically in an integrally rotatable manner and a large diameter gear  632  fit outwardly to one gear shaft  611  (the upper one in the case of  FIG. 5 ) concentrically in an integrally rotatable manner and meshed with the small diameter gear  631 . Accordingly, the driving of the fifth drive motor  62  is transmitted to the upper gear shaft  611  via the drive shaft  621 , the small diameter  631 , and the large diameter gear  632  to rotate the upper shredder gear  61 . The lower shredder gear  61  meshed with the upper shredder gear  61  thus rotates, too. The bottle main body P 1  fed to the mesh position after the breaking processing is shredded as a pair of the shredder gears  61  rotate. The chips P 3  are thus formed. 
     The chip storing portion  80  is provided directly downstream (front position) of the shredder portion  60 . The chip storing portion  80  includes a chip storing vessel  81  in the shape of a rectangular prism with the top surface fully opened and a flexible container bag  82  for bottle main body attached to the chip storing vessel  81  in a state where the top surface is opened. The chips P 3  formed by shredding the bottle main bodies P 1  by the shredder portion  60  are collected into the flexible container bag  82 . 
     As has been described in detail, the factory truck  10  of the first embodiment relates to a factory truck  10  as an auto vehicle capable of processing waste matter that cuts the pet bottles P made of PET, which is a recyclable material, into chips P 3  while collecting the pet bottles P. The aligning portion  30  to align the pet bottles P successively fed therein via the loading portion  20 , the processing portion  40  to apply chipping to the pet bottles P aligned by the aligning portion  30 , and the chip storing portion  80  to store chips formed by the processing portion  40 , are provided on the deck  12 . 
     According to this configuration, the collected pet bottles P are aligned serially as they are successively loaded into the aligning portion  30  so that they are fed into the processing portion  40  in a state that facilitates the processing thereafter and shredded into chips as they are subjected to the shredding processing. The chips thus obtained are stored in the chip storing portion  80 . 
     In this manner, it is configured in such a manner that the aligning portion  30  to align the pet bottles P is provided on the deck  12  of the auto vehicle so that chipping is applied successively to the pet bottles P in an aligned state. This configuration eliminates the need for a tedious work to manually feed pet bottles P collected by the worker to the shredder one by one to shred them into chips as in the conventional manner. Consequently, it becomes possible to markedly enhance the workability in chipping of the pet bottles P using an auto vehicle, which can increase the efficiency significantly in chipping of the pet bottles P. 
     The processing portion  40  includes the sorting portion  50  that breaks pet bottles P aligned by the aligning portion  30  to sort the bottle main bodies P 1  as the target matter and the accessories P 2 , such as mouth rings and caps, the shredder portion  60  that applies the shredding processing to the target matter sorted out by the sorting portion  50  and shreds the targeted matter into chips, and the accessory storing portion  59  that stores the accessories P 2  sorted out by the sorting portion  50 . 
     The collected pet bottles P are therefore aligned by the aligning portion  30  and introduced into the sorting portion  50  in a state that facilitates the processing thereafter. The pet bottles P introduced into the sorting portion  50  are broken into pieces, which are sorted to broken pieces of the bottle main bodies P 1  as the target matter and the accessories P 2 , such as mouth rings and caps. Subsequently, the bottle main bodies P 1  are shredded into chips by the shredding processing in the shredding portion  60  and stored in the chip storing portion  80 , whereas the sorted accessories P 2  are stored in the accessory storing portion  59 . 
     In this manner, it is configured in such a manner that the pet bottles P are broken and the accessories P 2 , such as mouth rings, are removed from the bottle main bodies P 1  in the sorting portion  50 . It is therefore possible to effectively prevent the occurrence of an inconvenience that the accessories P 2 , such as mouth rings, made of a different material are mixed into the chips of the bottle main bodies P 1 . 
     The sorting portion  50  includes the axial cutter device  51  that longitudinally cuts each pet bottle P at least into two pieces and the sieve device  58  as a separation device that separates the longitudinal cut pieces longitudinally cut by the axial cutter device  51  to the bottle main bodies P 1  and the accessories P 2 . Accordingly, each pet bottle P together with the accessory P 2 , such as a mouth ring, is longitudinally cut at least into two pieces by the axial cutter device  51 . Hence, even when the accessory P 2 , such as a mouth ring, is threaded into the bottle main body P 1  and screwed shut, the accessory P 2  can be removed easily from the bottle main body P 1 . 
     The sieve device  58  that collects the bottle main bodies P 1  as the remaining matter and collects the accessories P 2  as the passing matter is adopted as the sieve device. Accordingly, by feeding the pet bottles P longitudinally cut by the axial cutter device  51  to the sieve device  58 , the bottle main bodies P 1  formed by the longitudinally cutting processing are collected as the remaining matter whereas the accessories P 2 , such as mouth rings having a small volume, are sifted out as the passing matter. By adopting the sieve device  58  as the separation device in this manner, it becomes possible to separate the bottle main bodies P 1  and the accessories P 2  in a reliable manner while making the structure of the separation device simpler. 
     The sieve device  58  has the suction device  70  that removes the light accessories P 2 ′, such as labels wrapped on the pet bottles P, by suction with an air flow while the bottle main bodies P 1  are passing through the sieve device  58 . Hence, in a case where the labels are wrapped on the pet bottles P, the light accessories P 2 ′ are also broken by the breaking processing of the pet bottles P and thereby separated from the bottle main bodies P 1 . The light accessories P 2 ′ thus separated are removed as they are sucked into the suction device  70  with an air flow. By providing the suction device  70  to provide the capability of sucking the light accessories P 2 ′ in this manner, even when the light accessories P 2 ′ are wrapped on the bottle main bodies P 1 , the light accessories P 2 ′ are removed from the bottle main bodies P 1 . It thus becomes possible to prevent the occurrence of an inconvenience that the light accessories P 2 ′ made of a different material are mixed into the bottle main bodies P 1 . 
     The shredder portion  60  includes a pair of the shredder gears  61  configured to mesh with each other so that the bottle main bodies P 1  are fed to the mutually meshed portion. The broken bottle main bodies P 1  are introduced into the mesh position of the shredder gears  61  rotating while being meshed with each other and continuously shredded into chips in succession. Hence, in comparison with a case where a cutter device adopting a reciprocating way is used, it is possible to markedly enhance efficiency of the shredding processing. 
       FIG. 6  is a schematic side view of a factory truck according to a second embodiment of the invention. The indication of direction using Y in  FIG. 6  is the same as in  FIG. 1  (−Y: frontward, +Y: rearward). In the second embodiment, a factory truck (auto vehicle capable of processing waste matter)  10 ′ is to apply chipping to so-called steel cans S made of iron or iron alloy by selecting the steel cans S as the subject. 
     As is shown in  FIG. 6 , the aligning portion  30  provided on a deck  12 ′ of the factory truck  10 ′ has a selection device  36  provided at the downstream end to select steel cans S from aligned cans using a magnetic force. 
     The selection device  36  includes a housing  361  inclined to point downward to the front from the downstream end of the aligning portion  30 , a pair of magnet drums  362  paired in the front-rear direction and enclosed in the housing  36 , a front-rear pair of blades  363  provided so that the tip edge portions abut on the peripheral surfaces of the corresponding magnet drums  362  at the front positions. 
     A pair of the magnets  362  is set in such a manner that the one in the front is slightly lower than the one in the rear. A plurality of permanent magnets are attached to each magnet drum  362  all along the inner peripheral surface at regular pitches. Accordingly, when the magnet drums  362  are rotated in a counterclockwise direction about the drum center by the driving of an unillustrated drive motor, each time a can is delivered to the selection device  36  from the aligning portion  30 , in a case where this can is a steel can S, the steel can S is attracted to the peripheral surface of the magnet drum  362  by the action of the magnets. 
     The steel can S attracted to the peripheral surface of the magnet drum  362  is then forced off by the blade  363  as the magnet drum  362  rotates and attracted to the magnet drum  362  on the downstream side, after which it is again forced off by the blade  363  and fed to compression rollers  510  described below. 
     A steel can S that the magnet drum  362  on the upstream side failed to attract is therefore attracted by the magnet drum  362  on the downstream side. In this manner, by providing the magnet drums  362  in two stages, it becomes possible to pick up steel cans S in a more reliable manner. 
     Meanwhile, in a case where a can from the aligning portion  30  is not a steel can S, this can is attracted to neither of the magnet drums  362  and falls down from an introduction hole provided on an appropriate point in the bottom plate of the housing  361  and collected into a flexible container bag  591 ′ for non-ferrous can collection attached to a non-ferrous can storing portion  59 ′ through a chute  364 . 
     A top-bottom pair of compression rollers (compression roller pair)  510  having a diameter dimension considerably larger than the diameter dimension of steel cans S is provided downstream of the selection device  36  instead of the axial cutter device  51 . In the second embodiment, a processing portion  40 ′ includes the selection device  36 , the compression rollers  510 , and the shredder portion  60 . 
     The compression rollers  510  in a pair are axially supported by their own roller shafts  511  extending in the right-left direction (a direction perpendicular to the sheet surface of  FIG. 6 ) in a rotatable manner in opposite directions (the upper compression roller  510  rotates in a clockwise direction and the lower compression roller  510  rotates in a counterclockwise direction) by the driving of an unillustrated motor. 
     Accordingly, steel cans S introduced downstream from the selection device  36  are pulled in a space between a top-bottom pair of the compression rollers  510  rotating in opposite directions and flattened by the compression processing. Flattened steel cans S 1  formed by the compression processing are introduced into the shredder portion  60  configured in the same manner as the counterpart of the first embodiment and chips S 2  are formed therein. The chips S 2  thus obtained are collected into a flexile container bag  82  inside a chip storing vessel  81  provided on a chip storing portion  80  same as the counterpart of the first embodiment. 
     According to the factory truck  10 ′ of the second embodiment, of the metal cans, only the steel cans S collected by the action of electromagnets of the selection device  36  are fed into the compression rollers  510  and subjected to the compression processing, after which the steel cans S are subjected to shredding processing and shredded into the chips S 2  in the shredder portion  60 . Hence, chipping can be applied automatically to the steel cans S alone without having to make a selection as to whether collected cans are steel cans S or aluminum cans. It thus becomes possible to make intermediate processing to recycle cans more efficient. 
     It should be appreciated that the invention is not limited to the embodiments above and it is understood that the invention includes the following contents. 
     (1) In the embodiments above, pet bottles P or steel cans S are first loaded into the loading portion  20  of the factory truck  10  or  10 ′. However, it may be configured in such a manner that pet bottles P or steel cans S are directly loaded into the aligning portion  30  without providing the loading portion  20 . 
     (2) In the factory truck  10  of the first embodiment above, pet bottles P are fed one by one from the aligning portion  30  to the axial cutter device  51  on the downstream side. However, instead of this configuration, it may be configured in such a manner that more than one pair of the rail members  52  is provided, so that a plurality of pet bottles P are subjected to the breaking processing by the band saws  54  simultaneously. 
     (3) In the first embodiment above, the band saw  54  is adopted to longitudinally cut the pet bottles P. However, it may be configured in such a manner that pet bottles P are broken by press processing instead of using the band saw  54 . 
     (4) In the first embodiment above, the description was given using PET containers as an example of waste matter subjected to chipping. In the invention, however, waste matter is not limited to those made of PET and a material subjected to chipping may be waste matter made of synthetic resin of another type. 
     (5) In order to apply chipping to container waste matter efficiently using the factory truck  10  or  10 ′ of the above embodiments, as is shown in  FIG. 7 , it may be preferable to run a shuttle truck  15  used exclusively to store the chips P 3  or S 2  to accompany the factory truck  10  or  10 ′. This is because the capacity of the chip storing portion  80  of the factory truck  10  or  10 ′ cannot be increased significantly, and it is quite inefficient for the factory truck  10  or  10 ′ to return to the recycle factory F each time the chip storing portion  80  becomes full. 
     By running the shuttle truck  15  to accompany the factor truck  10  or  10 ′, the chips P 3  or S 2  are discharged from the chip storing portion  80  of the factory truck  10  or  10 ′ each time the chip storing portion  80  of the factory truck  10  or  10 ′ becomes full and transferred to the deck of the shuttle truck  15  on site. The need for the factory truck  10  or  10 ′ to return to the recycle factory F in each occasion can be thus eliminated, which can in turn enhance the chipping efficiency of the factory truck  10  or  10 ′. 
     The shuttle truck  15  transports the chips P 3  or S 2  to the recycle factory F when it becomes full of the chips P 3  or S 2 . In other words, each time the deck becomes full of the chips P 3  or S 2 , the shuttle truck  15  shuttles between the factory truck  10  or  10 ′ and the recycle factory F. 
     Technical characteristics of the embodiments above are summarized as follows. 
     The auto vehicle described above is an auto vehicle capable of processing waste matter that applies a predetermined processing to waste matter made of a recyclable material while collecting the waste matter, and includes: an aligning portion configured to align loaded waste matter; a processing portion configured to apply chipping to the waste matter aligned by the aligning portion; and a chip storing portion configured to store chips formed by the processing portion. 
     According to the auto vehicle capable of processing waste matter described above, collected water matter is aligned serially when loaded into the aligning portion and fed into the processing portion in this state and shredded. This configuration eliminates the need for a tedious work to manually feed waste matter collected by the worker to the shredder one by one to shred the waste matter into chips as in the conventional manner. Consequently, it becomes possible to markedly enhance the workability in chipping of waste matter using an auto vehicle. 
     It may be preferable that the waste matter is a bottle made of synthetic resin, and that the processing portion includes a sorting portion configured to break the bottle aligned by the aligning portion and to sort broken pieces of the bottle to targeted matter to be collected and an accessory, a shredder portion configured to shred the target matter sorted by the sorting portion into the chips by applying shredding processing, and an accessory storing portion configured to store the accessory sorted by the sorting portion. 
     According to this configuration, collected bottles made of synthetic resin are aligned by the aligning portion and introduced into the sorting portion in a state that facilitates the processing thereafter. The bottles introduced into the sorting portion are broken into pieces, which are sorted to broken pieces of the bottle main bodies, which are targeted matter to be collected, and accessories, such as mouth rings. The target matter is subsequently shredded into chips by the shredding processing in the shredder portion and stored into the chip storing portion. Meanwhile, the sorted accessories are stored into the accessory storing portion. 
     As has been described, the bottles are broken by the sorting portion and the accessories, such as mouth rings, are removed from the bottle main bodies. It thus becomes possible to effectively prevent the occurrence of an inconvenience that the accessories, such as mouth rings, made of a different material are mixed into the chips of the bottle main bodies. 
     It may be preferable that the sorting portion includes an axial cutter device configured to longitudinally cut the bottle at least into two pieces, and a separation device configured to separate cut pieces longitudinally cut by the axial cutter device to the target matter and the accessory. 
     According to this configuration, because the bottles together with the accessories, such as mouth rings, are longitudinally cut into at least two pieces by the axial cutter device, for example, even when the accessories, such as mouth rings, are threaded into the bottle main bodies and screwed shut, the accessories can be readily removed from the bottle main bodies. The accessories thus removed are separated from the bottle main bodies by the separation device. 
     It may be preferable that the separation device includes a sieve device configured to collect the target matter as remaining matter and collect the accessory as passing matter. 
     According to this configuration, by feeding the bottles in a state longitudinally cut by the axial cutter device to the sieve device, the target matter on the bottle main body side formed by the longitudinally cutting processing are collected as the remaining matter whereas the accessories, such as mouth rings having a small volume, are sifted out as the passing matter. In this manner, by adopting the sieve device as the separation device, it becomes possible to achieve separation processing of the target matter and the accessories in a reliable manner while making the structure of the separation device simpler. 
     It may be preferable that the separation device has a suction device configured to remove a label wrapped on the bottle by suction. 
     According to this configuration, in a case where labels are wrapped on the bottles, the labels are also broken and separated from the bottles by the breaking processing of the bottles. The separated labels are removed as they are sucked into the sucking device with an air flow. In this manner, by providing the sucking device to provide the capability of sucking the labels, even when the labels are wrapped on the bottle main bodies, the labels are removed from the bottom main bodies. It thus becomes possible to prevent the occurrence of an inconvenience that labels made of a different material are mixed into the target matter. 
     It may be preferable that the shredder portion is provided with a shredder gear pair configured in such a manner that the target matter is fed into a mutually meshed portion. 
     According to this configuration, the broken targeted matter to be collected is introduced into the mesh position of the shredding gear pair rotating while being meshed with each other and continuously shredded into chips in succession. Hence, in comparison with a case where a cutter device adopting a reciprocating way is used, it is possible to markedly enhance efficiency of the shredding processing. 
     It may be preferable that: the waste matter is a can made of magnetic metal, such as iron or iron alloy; the aligning portion has a selection device configured to select cans made of magnetic metal among aligned cans using a magnetic force; and the processing portion has a compression portion configured to apply compression processing successively to selected cans, and a shredder portion configured to shred the cans compressed by the compression portion into chips by applying shredding processing. 
     According to this configuration, collected cans made of magnetic metal, such as iron or iron alloy, are introduced into the selecting device one by one after they are aligned by the aligning portion, and cans made of magnetic metal are selected by applying selection processing using a magnetic force. The cans made of magnetic metal thus selected are subjected to compression processing in the compressing portion. The cans made of magnetic metal after the compression processing are subsequently shredded into chips by the shredding processing in the shredder portion and the chips are stored into the chip storing portion. 
     As has been described, with the aim of recycling, cans made of magnetic metal are selected by the selecting device using a magnetic force and shredded into chips after the compression processing is applied. It thus becomes possible to effectively prevent the occurrence of an inconvenience that a material other than magnetic metal, such as aluminum, is mixed into the chips. 
     It may be preferable that the compression portion is provided with a compression roller pair configured in such a manner that the cans are fed to a portion where peripheral surfaces oppose each other. 
     According to this configuration, the compression processing can be applied to the cans by merely feeding the cans to the opposing portion of the peripheral surfaces of the compression roller pair rotating in the opposite directions. Accordingly, in comparison with a type that applies compression processing to cans using, for example, a reciprocating way, the structure of the compressing portion can be simpler. 
     It may be preferable that the processing portion is provided with a vibration providing mechanism configured to provide vibrations to the waste matter. 
     According to this configuration, vibrations are provided on the waste matter in the processing portion by the vibration providing mechanism. It thus becomes possible to apply the respective types of processing to the waste matter in the processing portion efficiently and in a reliable manner by these vibrations. 
     This application is based on Japanese Patent application No. 2007-232779 filed in Japan on Sep. 7, 2007, the contents of which are hereby incorporated by reference.
