Abstract:
A wrapping implement is mounted to a rear location of a large round baler with connections permitting its quick attachment to, and detachment from, the baler. The wrapping implement includes a guidance ring that is essentially oriented vertically for guiding at least one wrapping material carrier about its periphery. The baler is equipped with a bale conveyor that receives a bale discharged from the baling chamber and transfers the bale to a bale carrier mounted to the guidance ring. The carrier supports and effects or permits the rotation of the supported cylindrical bale, where during the wrapping process the axis of rotation of the cylindrical bale extends perpendicular to the central axis of the circle of movement of the wrapping material carrier.

Description:
FIELD OF THE INVENTION  
         [0001]    The invention concerns a wrapping implement for the enveloping of a cylindrical bale with a run of enveloping material.  
         BACKGROUND OF THE INVENTION  
         [0002]    DE 196 54 982 A1 discloses a wrapping arrangement for a small bale of grass or straw that can be attached to a vehicle and wraps small bales, having either a circular or a rectangular cross section, with foil. For this purpose, the small bales are lined up in the form of a queue, aligned with each other with their end faces, but may also be wrapped individually. It is not apparent how the small bales are brought into this position and it seems that these small bales are of a small diameter.  
           [0003]    DE 40 21 307 A1 reveals a large baler with a comparable wrapping arrangement for slab-shaped bales that are conducted to the wrapping arrangement in the same way and wrapped by it.  
           [0004]    Another embodiment of a large round baler combined with a wrapping arrangement is revealed by US 5822967 A1, in which indeed two rolls with wrapping material rotate about a vertical axis and the cylindrical bale can be rotated about a horizontal axis during the wrapping process. An arm to take up the wrapping arrangement extends considerably beyond the large round baler, even in a non-operating position, which is not conducive to permitting good maneuverability. Furthermore, the rotating arms with the rolls must be brought to the side in a non-operating position during each loading and unloading process of the large round baler.  
           [0005]    EP 1 210 861 A2 is a large round baler with a wrapping arrangement attached at the rear that can be removed for a non-operating condition. During operation, however, the combination provides a great length of the entire vehicle train.  
           [0006]    EP 1 050 207 A2 discloses a bale wrapping arrangement, in the form of a trailer, that can be coupled behind an agricultural tractor, and raises cylindrical bales lying on the ground by means of a fork to a wrapping table.  
         SUMMARY OF THE INVENTION  
         [0007]    The problem underlying the invention is seen in the fact that the combination of a known large round baler with a wrapping arrangement that is also known always leads to an extended vehicle train.  
           [0008]    According to the present invention, there is provided a novel bale wrapping implement for being mounted to large round baler.  
           [0009]    An object of the invention is to provide a bale wrapping implement which is designed such that an unduly long combined implement does not result when it is mounted to the rear of a large round baler. More specifically, there is provided a bale wrapping implement, wherein the guidance ring for supporting the wrapping material supply roll or rolls is oriented in a near vertical plane.  
           [0010]    In this way, the wrapping implement can be held relatively short in the extent of its length and is appropriate for its operation as an attachment to a large round baler, as well as a free-standing implement, that is either equipped with a loading arrangement or is loaded by means of a front loader or the like. The pulley or the roll can be configured as smooth, with conveyer bridges or configured in some other manner in order to attain the rotating movement of the cylindrical bale or to increase it. The run of enveloping material is predominantly a stretch foil that is appropriate for improving the silage process. It is sufficient if either the pulley or the roll is driven in order to bring the cylindrical bale into rotation where the rotational speed is preferably variable. The pulley and the roll may be arranged together on the carrier; however, the roll can be attached independently of the carrier, for example, in the guidance ring or provided in a conveyor associated with the wrapping implement.  
           [0011]    If the carrier can be repositioned relative to the guidance ring, it is possible to bring the cylindrical bale into various positions relative to it. This also makes it possible to deposit the cylindrical bale on the ground or even to lift it up.  
           [0012]    The wrapping implement can be positioned in a stationary location on the ground in order to remain in a non-operating position or to be operated. In the non-operating position, the carrier can also be used for retaining. If operation is to be performed with the guidance ring set down, or the guidance ring is to be stabilized, it is useful to provide another support. The support may selectively be adjustable in length, in a known manner, and/or it may be repositioned by outside force.  
           [0013]    The use of a buttress on the carrier provides the advantage that the cylindrical bale does not fall off the carrier during a repositioning of the carrier, for example, for the unloading of the cylindrical bale, which otherwise could possibly occur if the spacing between the pulley and the roll should change.  
           [0014]    A circulating movement of the wrapping material carrier along a circular path can be generated by the guidance ring if it is provided with a rotating ring that can be rotated by a motor in a slotted guidance housing. The wrapping material carrier conventionally is a spool, supported in bearings, free to rotate, on which hundreds or thousands of meters of stretch foil or the like are wrapped. For the guidance ring, one or more wrapping material carriers may be provided. The slot in the guidance housing may be provided on a radially inner, as well as a radially outer, side of the guidance housing, that is, also on a forward or a rear end face. By the same token, an Omega-shaped or Hat-shaped profile could be used, the essential thing is only that the ring is guided and can accommodate at least one wrapping material carrier. On the other hand, the guidance housing can also be enclosed by a wrapping material carrier that then moves as on a rail or along a pipe, rod or the like. The movement can be produced by means of a rope pull, a chain or by means of a friction drive or a gear motor. The velocity of the wrapping material carrier may be constant as well as variable, and may conform, for example, to the number of wrapping material carriers used.  
           [0015]    In order for the cylindrical bale to be held, on the one hand, by a carrier, and on the other hand, be enclosed, trouble free, by enveloping material, the carrier is equipped with a frame or configured as a frame, that leaves an interior space through which the wrapping material carrier can be moved during the wrapping operation. Accordingly, the components of the frame, such as transverse and lengthwise struts, are located outside the path of movement of the wrapping material carriers. The frame may always be configured in that way or it may be arranged in that way only for the wrapping operation. The frame is not necessarily a closed structure; a fork-shaped or other configuration can also be considered, as long as it guarantees that the cylindrical bale is carried safely.  
           [0016]    If the guidance ring is to be transportable, and if necessary, can be attached to another implement, this can be accomplished basically as a permanent attachment or be difficult to remove. However, assembly time can be saved and flexibility can be increased if the guidance ring or quick connection devices are provided, such as hooks, couplings, pin connections, etc. Elements that are advantageous and reliable include, for example, elements that are used for the attachment of tools to front loaders or three-point implement hitches. Analogously, the wrapping implement could also be attached to a front loader and be easily transported. Similarly, the connection at the outlet of a large round baler or another type of baler is possible that produces, for example, slab-shaped bales.  
           [0017]    The cylindrical bale or basically any bale can be deposited on various surfaces, for example, its circumferential surface or one of its end faces. The deposit on an end face has the advantage that the cylindrical bale does not roll away when deposited on a slope. Such a deposit can be attained if the carrier is attached to the guidance ring at its circumferential direction so as to be repositioned, and thereby changes the inclination of the longitudinal center line of the cylindrical bale during the deposit process, until it is tilted onto its end face.  
           [0018]    In an alternative way, the bale can be deposited on its end face if the carrier can be adjusted vertically relative to the guidance ring, in particular pivoted.  
           [0019]    Particularly with cylindrical bales with a small diameter, an ejection sleeve provides the assurance that the cylindrical bale does not remain in the interval between the pulley and the roll when the carrier is moved for the deposit of the cylindrical bale. This ejection sleeve is brought into contact with the cylindrical bale as soon as the cylindrical bale is to leave its wrapping position. This can be performed at that time and to that degree that the carrier is repositioned, that is, it depends on this. It can also be performed by means of a pusher or the like that can act upon the cylindrical bale under the control of outside force.  
           [0020]    An actuating arrangement may be flexible if it is supported, for example, by a gas spring or a mechanical spring or by a pressurized medium such as oil or air escapes while being throttled by valves, etc. This flexibility has the advantage that the impact of an oncoming cylindrical bale is damped and that either a free-standing wrapping implement remains standing safely or that an attached wrapping implement does not transmit excessive forces to the connections.  
           [0021]    If the rotational speed of the pulley or the roll can be varied, either manually or automatically, the number and the overlap of the layers on the cylindrical bale can be varied or maintained at a constant value in case of a failure of a wrapping material carrier. Difficult conditions at the beginning or the end of the wrapping process can also be considered.  
           [0022]    The repositioning of the location of the pulley makes it possible to position the bale that is to be wrapped correctly on the carrier, as well as to assure that it lies on the carrier at the correct angle and thereby, safely. The repositioning is performed preferably by means of stepper motors and automatically, but can be performed in a simple version by means of a perforated rail or perforated plate or by means of a clamping arrangement.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0043]    Referring now to FIG. 1, there is shown a combination  10  of a large round baler  12  and a wrapping implement  14 .  
         [0044]    The large round baler  10  is preferably configured according to U.S. patent application Ser. No. 10/281,475, filed 25 Oct. 2002, whose disclosure is hereby incorporated herein. Basically the large round baler  10  may, however, be of any conventional configuration with a fixed or a variable baling chamber and may be applied in agriculture as well as in industrial operation. For this purpose, the large round baler  10  is provided with a frame  16 , a chassis  18 , baling elements  20 , a baling chamber  22 , a supply arrangement  24 , and a conveyor  26 .  
         [0045]    The frame  16  is formed by a welded and/or bolted assembly that ends at the front in a towbar  28 , is connected at the bottom with the chassis  18 , and is provided at the rear with upper and lower connecting points  30 ,  32 . The frame  16  includes side walls  34  that are not described in any further detail. The side walls  34  form opposite sides of a baling chamber  22 . In the region of the upper connecting point  30  on each side of the frame  16 , there is a hook element  76  that opens upwardly and is pivotally mounted for being repositioned by an actuating arrangement  78 .  
         [0046]    The chassis  18  can be configured in a tandem axle configuration with two axles  36 , as shown, or it may be provided with only a single sprung or unsprung axle  36  that carries a wheel on each side. The chassis  18  is located underneath the baling chamber  22  and is offset to the rear of it.  
         [0047]    In the embodiment shown, the baling elements  20  are configured as endless, flexible tensioning means, for example, as belts, bands, bar chains, etc., and generally surround, and thereby define, the circumference of the baling chamber  22 . The baling elements  20  are conducted over rolls  38 , whose position is in part rigid and in part movable. The use of rolls  38  that are movable in their attachment results in a baling chamber  22  of variable size. The movable rolls  38  are engaged by pivoted arms, in a way not shown, and repositioned as a function of operating condition. In the forward region of the baling chamber  22  facing the supply arrangement  24 , the baling elements  20  leave an inlet  40 , through which crop to be baled can be conveyed into the baling chamber  22 . In the rear lower region of the baling chamber  22 , an outlet  42  is formed when the corresponding rolls  38  are raised with the baling elements  20  and thereby open the baling chamber  22 .  
         [0048]    The baling chamber  22  is variable in its size, since the baling elements  20  are flexible. Instead of that, a baling chamber  22  could be formed whose size is invariable and that is surrounded, for example, by rolls or bands on axes that are unchangeable in their location. The baling chamber  22  is oriented in such a way that a cylindrical bale  44  contained in it rotates about a horizontal, central, cylindrical axis that extends transverse to the direction of operation.  
         [0049]    In this embodiment, the supply arrangement  24  contains a take-up device  46  in the form of a so-called pick-up that is followed by a conveying arrangement  48 , if necessary configured as a cutting arrangement, in order to grasp crop to be baled that is lying on the ground and convey it through the inlet  40  into the baling chamber  22 , where it is formed into a cylindrical bale  44 .  
         [0050]    As is illustrated in FIG. 5, the conveyor  26  is provided with a frame  50 , a conveying table  52 , a guide arrangement  54 , a first actuating arrangement  56 , and a second actuating arrangement  58 . The assignment of the conveyor  26  consists of taking up a cylindrical bale  44  delivered by the baling chamber  22  and to either convey it to the wrapping arrangement  14  or to deposit it on the ground.  
         [0051]    The frame  50  is configured as a two-piece component and includes a slide  60 , with rolls  62 , that is connected in a bearing  64  with a pivoting frame  66  so as to pivot vertically. The slide  60  with its rolls  62  is engaged in the guide arrangement  54  and can be moved inclined to the ground in the direction of operation. The rolls  62  are attached to the slide  60  in such a way that they are still retained in the guide arrangement  54  in each end position of the slide  60 . In a simplified configuration, guide shoes or the like may also be provided in place of the rolls  62 .  
         [0052]    The conveying table  52  contains at least two rolls  68  that are spaced from each other at a distance of less than the diameter of a completed cylindrical bale  44  and are mounted, free to rotate, on the pivoting frame  66 . In the preferred embodiment, an endless, flexible band  70  is slung over the rolls  68  that bridges the spacing between the rolls  68  and sags to a small amount. Fundamentally, such a band  70  is not required, and in its place, further rolls could be provided in case that the spacing is then to be bridged. An axis of rotation  72  of the roll  68  facing the wrapping implement  14  is used simultaneously as a bearing  64 . On the side of the pivoting frame  66  facing away from the wrapping implement  14 , a further roll  74  is provided alongside the roll  68  that is remote from the axis of rotation  72 . The roll  74  may be provided with a smaller diameter than the remaining rolls  68  and is offset relative to a plane through the axes of rotation of the rolls  68  so that a trough shape results in the shape of the conveying table  52 . The conveying table  52  can occupy a lower end position inclined forward and downward (see FIG. 5 in dashed lines), in which the cylindrical bale  44  is accepted from the baling chamber  22 , and an upper end position inclined upward and to the rear (see FIG. 5 in solid lines), in which it can deliver the cylindrical bale  44  into the wrapping implement  14 . The rolls  68  may be configured as free to rotate or may be driven. In the preferred embodiment, the rear roll  38  is driven, for example, by means of a hydraulic motor.  
         [0053]    In the simplest case, the guidance arrangement  54  consists of two U-shaped rails extending parallel to the longitudinal center plane of the large round baler  12  that can be bolted to the frame  16  of the large round baler  12  and that are open toward its longitudinal center plane. The guidance arrangement  54  extends at a small inclination of, for example, 30° from the ground upward and to the rear, and extends above the rear axle  36 . The interior of the guidance arrangement  54  is appropriate to take up the rolls  38 , free to rotate. The guidance arrangement  54  is configured in such a way that it still safely guides the slide  60  even in the operating condition according to FIG. 8. For this purpose, one-piece rails could be used, that for example, can be tilted about a horizontal bearing by means of a further actuating arrangement, not shown, if this should be necessary. In the preferred embodiment, the rails are configured, in particular, as can be seen in FIG. 8. According to that, the rails are two-piece components and contain a joint  116  above the rear axle  36  that connects both sections with each other so as to pivot vertically. If necessary, a section developing during the pivoting can be bridged by means of a curved piece. In this way it is possible that the slide  60  again slides downward after the cylindrical bale  44  is raised over the rear axle  36  and deposits the cylindrical bale  44  gently on the ground.  
         [0054]    The first actuating arrangement  56  is configured as a double-acting hydraulic motor having its cylinder end pivotally connected to the frame  16  of the large round baler  12  and having its rod end pivotally connected to the slide  60 . The orientation of the first actuating arrangement  56  is selected in such a way that its change in length produces a repositioning of the slide  60  in the guidance arrangement  54 . The first actuating arrangement  56  is controlled by means of electromagnetically controlled valves preferably from an on-board computer or manually. The stroke of the first actuating arrangement  56  is sufficient to move the slide  60  in both directions over the entire length of the guidance arrangement  54 .  
         [0055]    The second actuating arrangement  58  is also configured as a hydraulic motor, however, it is single-acting. The second actuating arrangement  58  has its head end pivotally to the slide  60  and has its rod end pivotally connected to the pivoting frame  66  of the conveying table  52 . The second actuating arrangement  58  is used to pivot the pivoting frame  66  out of its lower end position, if necessary with the cylindrical bale  44  lying on it, into its upper end position, and to lower it under control on the basis of the force of gravity. The second actuating arrangement  58  is also controlled electrically and preferably by means of an on-board computer.  
         [0056]    Fundamentally, the two actuating arrangements  56 ,  58  could also be operated mechanically, electrically or pneumatically.  
         [0057]    At this state of the description, it will be appreciated that the conveying table  52  could perform without the attached wrapping implement  14 . According to FIG. 8, only the large round baler  12  is provided, which holds the conveying table  52  at the outlet side of the baling chamber  22 . As soon as the baling elements  20  and the rolls  38  carrying them are raised in order to open the baling chamber  22 , the cylindrical bale  44  can leave it and fall onto the conveying table  52 , which can also be seen in FIG. 5. The conveying table  52  is then operated to move the bale  44  to the rear over the axle  36  and slides downward on the section of the guidance arrangement  54  that is tilted downward, after crossing one-half of the path, in order to deposit the cylindrical bale  44  on the ground.  
         [0058]    In the preferred embodiments, the wrapping implement  14  is configured as an independent unit, that can be connected to the large round baler  12  in a quick assembly method without the use of tools. The wrapping implement  14  can also be configured in such a way, which is not shown, that it can be attached to a front loader or a rear loader, a telehandler, a three-point implement hitch or the like in order to be easily removable. As can best be seen in FIGS. 2 and 4, the wrapping implement  14  includes a guidance ring  80 , a carrier  82 , at least one wrapping material carrier  84 , a third actuating arrangement  86 , and a support  88 .  
         [0059]    The guidance ring  80  has a circular cross section that is almost completely closed, but remains open only for a slot, not shown or described in any further detail, in a guidance housing  108 . In the installed condition of the wrapping implement  14 , the guidance ring  80  assumes an upright position of nearly 90° to the ground and is carried by the frame  16  of the large round baler  12 . In place of a nearly closed cross section, an Omega profile or the like could be used. In the upper one-fourth of the guidance ring  80 , a retainer  90  is provided at the guidance housing  108  that can be grasped by the hook element  76  at the frame  16  and that is configured, for example, as a pin or the like. The guidance ring  80  or the guidance housing  108  is provided with a diameter that permits the cylindrical bale  44  to pass without any change in its orientation, so that is can be deposited on the carrier  82 . In the guidance housing  108 , a ring  110  is located that is preferably closed and that can rotate in the guidance housing  108 . The ring  110  is moved, in particular, by means of a hydraulically driven motor  112  that makes contact with the ring  110  through an opening in the guidance housing  108 . The drive of the motor  112  is performed either by a positive locking connection, for example, a rack, pinion or through a friction locking connection, for example, friction wheel, and transmitted to the ring  110 . In this embodiment, the motor  112  is located and protected in the lower region of the guidance housing  108  and is brought into motion by means of electromagnetically controlled valves, where the control signals again may originate from an on-board computer. Indeed, the motor  112 , or several like motors, may be attached to other locations of the guidance housing  108 , which depends on the spacial possibilities and environmental conditions (incidence of dirt, mechanical effects). The movement of the ring  110  within the guidance housing  108  can proceed with little friction if guide rolls, not shown, or the like support and guide the ring  110 . The ring  110  may consist of metal as well as a plastic. Nearly at the lower end of the guidance housing  108 , coupling elements  114  are provided at its front side for engagement with the lower connecting points  32  on the baler frame  16 .  
         [0060]    The carrier  82  includes a frame  92 , a roll  94 , and a side panel  96 . The carrier  82  is required to carry the cylindrical bale  44  during the wrapping process and to rotate it about its cylinder axis or to engage it, free to rotate. After the wrapping process, the carrier  82  is required to deposit the wrapped cylindrical bale  44  on the ground. The carrier  82  is located at the lower one-fourth or one-fifth of the guidance ring  80 .  
         [0061]    As can be seen in FIG. 2 the frame  92  is provided with a transverse strut  98  and lengthwise struts  100  in a horizontal position. The transverse strut  98  is located at such a distance from the guidance ring  80  that the wrapping material carrier  84  can be moved through the interior space. The transverse strut  98  has a length approximately equal to the diameter of the guidance ring  80 . The lengthwise struts  100  connect the transverse strut  98  with the guidance ring  80 . For this purpose, the lengthwise struts  100  extend in the direction of operation and engage the guidance ring  80  in a bearing  102  so as to pivot vertically. For this purpose, the lengthwise struts  100  are bent at right angles, if necessary, from the forward end region towards the guidance housing  108  or pillow blocks are applied to the latter that bridge the sideways distance between the guidance housing  108  and the lengthwise struts  100 . Within the space enclosed by the frame  92  in the plan view and connected to the rear side of the guidance housing  108 , an ejection sleeve  118  is located. This ejection sleeve  118  consists of a small rigid frame that projects beyond the lengthwise struts  100  and projects beyond the enclosed space when the carrier  82  is tilted downward (see FIGS. 4 and 7). This ejection sleeve  118  prevents a small cylindrical bale  44  from resting on the rear roll  94  even when the carrier  82  has been tilted downward. Rather, upon the lowering of the carrier  82 , its center is moved over the roll  94  so that it rolls down from the carrier  82 .  
         [0062]    The roll  94  is applied to the transverse strut  98 , free to rotate in pillow blocks, and extends horizontally transverse to the direction of operation of the combination  10 . Hence, it is in contact with the circumferential surface of the cylindrical bale  44  that was taken up. The roll  94  is approximately as wide as the cylindrical bale  44  and is driven in case that the roll  38  is not driven.  
         [0063]    The panel  96  is configured as a bow, a sheet metal shoulder or the like, and is located on the opposite side of the frame  92  from the roll  94 . The panel  96  is formed or attached in such a way that it is supported on the rear pulley  68 , on its axis of rotation or the like, during corresponding positions of the conveying table  52  and the carrier  82 , as this is shown in FIG. 5. For this purpose, the panel  96  need not extend over the entire width of the pulley  68 . The requirement of the panel  96  is to retain the cylindrical bale  44  on the carrier  82  even after the conveying table  52  is again tilted forward and downward. The position of the panel  96  with the rear roll  68  and the pulley  94  are selected in such a way that they position the cylindrical bale  44  during the wrapping process centrally to the path of movement of the wrapping material carrier  84 .  
         [0064]    As can be seen in FIG. 4, the wrapping material carrier  84  includes a spindle  104  and a wrapping material roll  106 . In addition, and not shown, on the wrapping material carrier  84 , there is also a pre-loading arrangement, a cutting arrangement, and/or a contact pressure arrangement as these are known in themselves. The spindle  104  is fastened in the axial direction on the ring  110 , extends through the slot in the guidance housing  108 , and carries the wrapping material roll  106  in its outer region, free to rotate and secured axially. The wrapping material roll  106  consists of a considerable length of wrapping material wrapped onto the roll, consisting of plastic, that is commercially available.  
         [0065]    A third actuating arrangement  86  is also configured as a hydraulic cylinder, has its head end pivotally coupled to the guidance housing  108 , and has its rod end pivotally coupled to the underside of the carrier  82 . As are the other actuating arrangements, the third actuating arrangement  86  is preferably controlled electromagnetically by means of an on-board computer. By means of the third actuating arrangement  86 , the carrier  82  can be brought into an intermediate position in which it extends generally vertically to the plane of the principal extent of the guidance housing  108 , as shown in FIG. 1, and can be brought into a raised position, wherein it is displaced approximately 30° upward from its intermediate position, as shown in FIG. 5. The carrier  82  can also be moved to a lowered position, wherein the carrier  82  is used as a support for the guidance ring  80  when the latter is detached from the baler  12 . The third actuating arrangement  86  may be equipped or connected with a pressure accumulator so that it can deflect under pressure in a direction, particularly a downward direction.  
         [0066]    The support  88  is attached in the lower half of the guidance housing  108 . It may consist of two individual legs or struts or it may consist of a U-shaped bow that folds away from the plane of the guidance housing  108  to the front and can be locked by means not shown. As can be seen, in particular from FIG. 4, the result is that the wrapping implement  14  in the unassembled condition rests in front on the support  88  and at the rear on the carrier  82  or the lengthwise struts  98  and/or transverse struts  100 .  
         [0067]    On the basis of the foregoing description, the first embodiment operates as follows, where in addition it should be noted that in every case, the cylindrical bale  44  is wrapped or enclosed in net before its release from the baling chamber  22 , in order to maintain its compact and cylindrical shape. The combination  10  and the wrapping implement  14  could operate without this wrapping or enveloping process but the quality of the bale would be worse.  
         [0068]    The large round baler  12  can be driven individually or in the combination  10  with the wrapping implement  14 . If it is operated individually, only the conveyor  26  is attached that can take up the cylindrical bale  44  and deposit it on the ground, as was described above.  
         [0069]    When the large round baler  12  and the wrapping implement  14  are connected with each other, the conveyor  26  is not used to deposit the cylindrical bale  44  on the ground, but is used for its transfer to the wrapping implement  14 . According to FIG. 5, the slide  60  is located in its forward, lower acceptance position for the acceptance of the finished cylindrical bale  44  from the baling chamber  22 . As soon as the cylindrical bale  44  reaches the conveying table  52 , it is in contact with the forward, further roll  74  and cannot roll down off the conveyor  26  when this is conducted by means of the first actuating arrangement  56  at an angle to the rear within the guidance arrangement  54 . As soon as the slide  60  has reached its rear and upper end position, the second actuating arrangement  58  is extended so that the slide  60  tilts upward at the front about the bearing  64  and the cylindrical bale  44  lies upon the carrier  82 . When it is lying on the carrier  82 , the latter is pivoted upward at the rear through approximately 30°, and the panel  96  lies on the rear roll  68  or in its region so that no troublesome gap develops between the conveying table  52  and the carrier  82 . In this condition, the load carrying surfaces of the conveying table  52  and the carrier  82  extend in the shape of a throat to each other, so that the cylindrical bale  44  is grasped securely and cannot roll down. If the third actuating arrangement  86  interacts with a pressure accumulator, which is not necessarily required, it deflects slightly under the impact of the cylindrical bale  44 , and reduces its impact somewhat. Then the cylindrical bale  44  rests on the rear roll  68  of the conveying table  52  and the roll  94 , where its center of gravity is located between the two. Following this, the carrier  82  is lowered into its position perpendicular to the guidance housing  108 , in which it continues to rest on the roll  68  and the roll  94 , as is shown in FIG. 6. In the position according to FIG. 6, the roll  68  or the pulley  94  is driven so that the cylindrical bale  44  will rotate about its central cylindrical axis, extending horizontally, transverse to the direction of operation of the combination  10 . Following this, the ring  110  in the guidance housing  108 , is brought into rotation by means of the motor or motors  112 , so that the wrapping material carriers  84  are moved along a vertical track about the cylindrical bale  44  and apply foil to it in a known manner. Since this is known in itself, the application, pressing, and cutting of the foil will not be further explained. It can be seen that the large round baler  12  in this position can already be operated to form a new cylindrical bale  44 , although the present cylindrical bale  44  is still being wrapped. During the wrapping process, the wrapping material carriers  84  also move through the interior space enclosed by the frame  92 . When the wrapping process has been completed and the foil has also been separated, the third actuating arrangement  86  is retracted and thereby the carrier  82  is lowered. During the lowering of the carrier  82 , it retracts behind the rear edge of the ejection sleeve  118 , so that the cylindrical bale  44  receives an additional impulse to the rear and rolls over the pulley  94  out of the region of the carrier  82 . Now the wrapping and depositing process is completed and a further cylindrical bale  44  can be accepted and wrapped.  
         [0070]    The further description concerns the second embodiment which generally corresponds to the first embodiment; differences exist in the repositioning of the slide  60 , the conveying table  52 , and in the position of the carrier  82  during the take-up of the cylindrical bale  44 .  
         [0071]    Thus, referring to FIG. 9, it can be seen that in place of two actuating arrangements  56  and  58 , only a single actuating arrangement  58 ′ is used that is connected in joints and configured as a hydraulic motor in the same way as the second actuating arrangement  58  according to the first embodiment. However, the actuating arrangement  58 ′ is provided with a considerably longer stroke and is preferably double-acting. Furthermore, a retainer  120  is attached to the slide  60 , in particular, at least on one side. Finally, a locking arrangement  122  is provided on the guidance housing  108 .  
         [0072]    The locking arrangement contains at least one hook  124  and a linkage  126 . The same number of hooks  124  as of retainers  120  are provided, and the hook or the hooks  124  are arranged and configured in such a way that in each case they are able to overlap a retainer  124  in a positive lock and retain it. Each hook  124  can pivot vertically about a bearing  128  and is provided with a hook nose  130  extending from the bearing  128  to the front and a lever  132  extending to the rear. Each hook  124  is attached to the guidance housing  108  preferably on its outside, so as to pivot vertically, in particular, in such a way that it can grasp the retainer  120  with the hook nose  130 , when the wrapping implement  14  is attached to the large round baler  12  and the slide  60  is moved to the rear up to the stop at the guidance housing  108 . Although the drawing is a hook nose  130  that is open upwards, a hook-nose opening downward could also be used.  
         [0073]    At least one linkage  126  is provided that is configured as a compression spring in this embodiment and that is arranged between the lever  132  and an extension of the frame  92  projecting forward beyond the bearing  102 . Instead of being configured as a compression spring, the linkage could also be configured as a rod, a rope pull, an extension spring, a rocker arm or the like. The essential thing here is that a relationship be established between the position of the hook  124  and of the carrier  82 . It is possible that two hooks  124  are provided, but that are controlled together, so that only one linkage  126  is required.  
         [0074]    In contrast to the illustration of FIG. 5 for the first embodiment, the carrier  82  is not raised when taking up a cylindrical bale  44 , but remains in its generally horizontal position. However, the operation of the actuating arrangement  86  as a shock absorber is preferably maintained.  
         [0075]    The operation of this second embodiment is described as follows. As soon as the cylindrical bale  44  lies upon the conveying table  52 , the actuating arrangement  58 ′ is extended and the slide  60  moves in the guidance arrangement  54  to the rear and upward so that the cylindrical bale  44  is conveyed to the carrier  82 . As soon as the slide  60  has reached its rear end position, the hook  124  grasps the retainer  120  and holds it rigidly in this position. The actuating arrangement  58 ′ is extended further and the conveying table  52  pivots upward about the bearing  64 , in the clockwise direction as seen in FIG. 10, in order to deposit the cylindrical bale  44  on the carrier  82 , until it rests on the pulley  94 . Following this, the actuating arrangement  58 ′ is either drained of its pressure, so that it is lowered, or pressure is applied to it and it retracts. As a result, the conveying table  52  is also lowered, and except for the rear roll  68 , is released from the circumferential surface of the cylindrical bale  44 . In the condition that now obtains and is shown in FIG. 11, the wrapping process can be performed as in the case of the first embodiment. As soon as the wrapping process is ended and the carrier  82  is tilted to the rear and downward, as is shown in FIG. 12, in order to deposit the cylindrical bale  44  on the ground, the extension of the carrier  82  presses on the linkage  126 , this in turn on the lever  132 , and thereby the hook nose  130  is lifted from the stop. The release of this positive lock now makes it possible for the actuating arrangement  58 ′ to be retracted completely and to move the slide  60  with the conveying table  52  into its accepting position underneath the baling chamber  22 , as shown in FIG. 12.  
         [0076]    A further embodiment is illustrated in FIGS. 13 through 17, which generally follows the first embodiment, but is provided with another carrier  82 ′.  
         [0077]    In contrast to the carrier  82  described so far, the carrier  82 ′ now used is provided with only one lengthwise strut  100 . For example, the strut  100  provided on the left side in the previous embodiments is missing. The carrier  82 ′ is the approximate shape of a fork, which however, is repositioned by means of the actuating arrangement  86  in the same way as in the first or the second embodiment. However, the bearing  102  and the actuating arrangement  86  are not provided on the guidance housing  108 , but on a sliding stand  134 . The sliding stand  134  is curved corresponding to the guidance housing  108  and engages on its outer circumferential surface in a positive lock along a curve of approximately 90°. For example, an Omega or a hat profile and rolls could be provided that are used to accommodate the sliding stand  134  on the guidance housing  108 . The sliding stand  134  is moved about the central axis of the guidance housing  108  by means of a motor  136 , which engages in a sprocket  138  on the circumferential surface of the housing  108 . Instead, a rope pull, a hydraulic cylinder, an electric motor or the like could be used, that cause at least an upward movement, while the downward movement is performed by the force of gravity alone.  
         [0078]    While the wrapping operation with this carrier  82 ′ corresponds to that of the other embodiments, this embodiment is provided with another and possibly additional deposit possibility, while the previous possibilities using the actuating arrangement  86  remain in effect.  
         [0079]    A further advantage of this carrier  82 ′ consists of the fact that it can deposit the cylindrical bale  44  on its end face, as it is shown in FIGS. 16 and 17. This type of deposit is particularly advantageous on a slope, since there the cylindrical bale  44  cannot roll away. As can be seen, in particular, from FIG. 17, the sliding stand  134  can be pivoted about the horizontal lengthwise axis of the wrapping implement  14  so far until the roll  94  and a buttress  140  located opposite them assume an inclination of approximately 45° to the ground, the buttress taking up a load only when the roll  68  of the conveying table  52  is not located in its rear end position. The buttress  140  may be a sheet metal plate, a roll, a strut or the like. In this position, the cylindrical bale  44  will tilt over the lower edge of the roll  94  and the buttress  140  and land on its end face and remain lying there. Depending on the configuration and the size of the cylindrical bale  44 , the tilting may occur earlier or later, with the timing in any case depending on when the center of gravity comes to lie to the side of the lower edge of the roll  94 . As soon as the cylindrical bale  44  has been deposited and the combination  10  has been operated past it, the carrier  82 ′ can be pivoted again into its original horizontal position, in which it can accept a new cylindrical bale  44 .  
         [0080]    The fourth embodiment, as shown in FIGS. 18 and 19, corresponds generally to the third embodiment. However, the deposit of the cylindrical bale  44  on its end face is performed in a different manner. The configuration of the large round baler  12  and the conveyor  26  corresponds to that of the previous embodiments.  
         [0081]    In contrast to the third embodiment, the carrier  82  is not fastened to a sliding stand  134 , but can be pivoted about a horizontal axis  142  extending generally in the direction of operation on which an arm  144  is supported in bearings, free to pivot.  
         [0082]    The axis  142  engages, on the one hand, the guidance housing  108 , and on the other hand, the arm  144 , rigidly or movably. The axis  142  is configured as a steel journal or the like and is preferably oriented with a slight inclination to the direction of operation, particularly to the side. The axis  142  or the shaft extends to the rear past the guidance housing  108  in order to take up the arm  144 , and extends to the front in order to be connected with a lever arm  146 .  
         [0083]    The arm  144  is rigidly connected with the lengthwise strut  100  and extends in a plane oriented parallel to the transverse strut  98 . The arm  144  extends very close to the guidance housing  108  and the buttress  140 . Between the arm  144  and the lengthwise strut  100 , the third actuating arrangement  86  extends, which brings the carrier  82  into its take-up and delivery position, as already described above.  
         [0084]    The lever arm  146  extends radially from the axis  142  and is connected at its end with a motor  136 ′. In the embodiment shown, the lever arm  146  extends in front of the guidance housing  108  and can be repositioned between an approximately 3 o&#39;clock and an approximately 50&#39;clock position, as considered when viewing the wrapping implement  14  from the rear.  
         [0085]    The motor  136 ′ is configured as a single-acting or as a double-acting hydraulic cylinder, that is connected at its other end to the guidance housing  108 , free to pivot. The motor  136 ′ is again repositioned automatically, that is, extended or retracted, preferably by means of an on-board computer using electromagnetic valves, not shown.  
         [0086]    On the basis of the foregoing description, the fourth embodiment operates as follows. The formation, the wrapping, the delivery and transport of the cylindrical bale  44  to the carrier  82 , and the enveloping of it with foil is performed in the manner described previously. In this position, the motor  136 ′ is extended and the carrier  82  with its roll  94  extend in a horizontal plane. As soon as the wrapping process is completed and the cylindrical bale  44  can be deposited on the ground, the motor  136 ′ is retracted and the carrier  82  tilts about or with the axis  142  in the counterclockwise direction as seen in FIG. 19, until it is inclined approximately 45° to the ground. In this position, the cylindrical bale  44  falls onto its end face. If the cylindrical bale  44  is to be deposited on its circumferential surface, the motor  136 ′ remains rigid and the actuating arrangement  86  is operated so that the cylindrical bale  44  reaches the ground in its usual manner.  
         [0087]    Having described the preferred embodiment, it will become apparent that various modifications can be made without departing from the scope of the invention as defined in the accompanying claims.
