CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to and the benefit of Korean Patent Application No. 10-2021-0007111, filed on Jan. 18, 2021, and Korean Patent Application No. 10-2021-0093748, filed on Jul. 16, 2021, the disclosure of which is incorporated herein by reference in its entirety. 
     BACKGROUND 
     1. Technical Field 
     The present invention relates to a film discharging device. 
     2. Description of the Related Art 
     A cathode ray tube (CRT), which is one of conventionally used display devices, has been mainly used in a monitor such as a TV, a measuring device, and an information terminal device, but due to the large weight or size of the CRT itself, it is not possible to actively respond to demand for miniaturization and light reduction of electronic products. 
     In order to replace the CRT, a liquid crystal display device with advantages of small size and light weight has been actively developed, and recently, has been developed to sufficiently function as a flat panel display device, and demand for the CRT has gradually increased. 
     An image realization principle of the liquid crystal display is to use the optical anisotropy and polarization properties of liquid crystal, and the liquid crystal includes a thin and long molecular structure, and has anisotropy having directionality in molecular arrangement and polarization properties in which a direction of the molecular arrangement changes depending on the magnitude of an electric field when placed in the electric field. Thus, the liquid crystal display includes, as a required component, a liquid crystal panel including a pair of transparent insulating substrates, which face each other and have respective electric field generating electrodes, and a liquid crystal layer interposed between the transparent insulating substrates, and displays various images using light transmittance that is changed when a direction of alignment of liquid crystal molecules is artificially adjusted through a change in an electric field between the electric field generating electrodes. 
     In this case, polarizing films for visualizing a change in orientation of liquid crystal of the liquid crystal display are disposed above and below the liquid crystal panel, respectively and transmit a polarized component of light that coincides with a transmission axis of reflection and transmission axes, and thus a degree of light transmission is determined depending on arrangement of transmission axes of the two polarizing films and the characteristics of arrangement of liquid crystal. 
     In general, a polarizing film product applied to a liquid crystal panel is manufactured via a slitting process of slitting a polarizing film fabric to have a width corresponding to the width of the polarizing film product, and a cutting process of cutting the slit polarizing film fabric to have a length corresponding to the length of the polarizing film product. In addition, polarizing film products discharged from a film discharging device of a film cutting apparatus for performing the cutting process are sequentially loaded on a load bogie and are then transferred and fed. 
     However, there is a limit in a film load capacity of the load bogie. Thus, conventionally, when a predetermined amount of polarizing film products are loaded in the load bogie, a product collection process of transferring the load bogie to a predetermined collection place and then collecting the polarizing film product from the load bogie to empty the load bogie in the state in which the slitting and cutting processes on the polarizing film fabric are stopped. Accordingly, conventionally, the slitting and cutting processes need to be stopped during the product collection process, and thus there is a problem in that the productivity of polarizing film products is lowered. 
     SUMMARY 
     Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a film discharging device that is improved to also continuously perform processes of manufacturing and processing film products when a product collection process of collecting the film products from a load bogie is performed.

     A film discharging device  1  according to an embodiment of the present invention may be a device applied to a film manufacturing system for cutting and processing a film fabric and processing the film fabric via various other methods to manufacture a film product F and may be provided to discharge and collect film products, which are manufactured in a predetermined processing form using various processing units included in the film manufacturing system, from the film manufacturing system. However, the present invention is not limited thereto, and the film discharging device  1  may be applied to various systems in which the film product F needs to be discharged, other than the film manufacturing system. Hereinafter, an example in which the film discharging device  1  is applied to the film manufacturing system will be described with regard to the present invention. 
     Referring to  FIG. 1 , the film discharging device  1  may include a supply unit  10  for supplying the film product F processed in a predetermined processing form, a branch unit  20  for selectively guiding the film product F supplied from the supply unit  10  to any one branch path of a predetermined first branch path P 1  and a predetermined second branch path P 2 , a first discharging unit  30  installed on the first branch path P 1  and configured to discharge the film product F guided to the first branch path P 1  by the branch unit  20 , a first loading unit  40  on which the film product F discharged from the first discharging unit  30  is loaded, a second discharging unit  50  installed on the second branch path P 2  and configured to discharge the film product F guided to the second branch path P 2  by the branch unit  20 , and a second loading unit  60  on which the film product F discharged from the second discharging unit  50  is loaded. 
     First, the supply unit  10  may include a cutting unit for cutting and processing a film fabric, and a supply conveyer  12  for receiving the film product F that is processed and manufactured in a predetermined processing form from a processing unit (not shown) of a film manufacturing system (not shown) for processing other film fabrics and transferring the film product F towards the branch unit  20 . A fore end of the supply conveyer  12  may be disposed in contact with the processing unit to accommodate the film product F passing through the processing unit thereon. A rear end of the supply conveyer  12  may be disposed in contact with a fore end of the branch unit  20 . As such, the supply unit  10  may receive the film product F from the processing unit and may then transfer the film product F towards the branch unit  20  to supply the film product F to the branch unit  20 . 
     Then, the branch unit  20  may include a branch conveyer  22 , arrangement of which is variably provided to selectively transfer the film product F transferred from the supply conveyer  12  to any one branch path of the first branch path P 1  and the second branch path P 2 . 
     The positions of the first branch path P 1  and the second branch path P 2  are not particularly limited. For example, as shown in  FIG. 1 , the first branch path P 1  and the second branch path P 2  may be set in such a way that the second branch path P 2  is positioned higher than the first branch path P 1  by a predetermined reference distance. 
     A fore end of the branch conveyer  22  may be disposed in contact with the rear end of the supply conveyer  12  to accommodate the film product F passing through the supply conveyer  12 . 
     The branch unit  20  may further include a conveyer rotating member  24  for raising and lowering a rear end of the branch conveyer  22  by rotating the branch conveyer  22  using the fore end of the branch conveyer  22  as a rotation shaft to change an alignment angle of the branch conveyer  22 . 
     The configuration of the conveyer rotating member  24  is not particularly limited. For example, as shown in  FIG. 2 , the conveyer rotating member  24  may be configured as a cylinder device. In this case, as shown in  FIG. 2 , the conveyer rotating member  24  may include a cylinder body  24   a  rotatably coupled to a bracket or other fixing members (not shown), and a cylinder rod  24   b  that reciprocates linearly within a predetermined stroke range by the cylinder body  24   a.    
     As shown in  FIG. 2 , one end of the cylinder rod  24   b  may be coupled to the branch conveyer  22  to rotate the branch conveyer  22  in a predetermined forward or reverse direction using the fore end as the rotation shaft depending on a movement direction of the cylinder rod  24   b  when the corresponding cylinder rod  24   b  reciprocates linearly by the cylinder body  24   a.    
     In this case, a first pulley  22   a  disposed at the fore end of the branch conveyer  22  among a pair of pulleys  22   a  and  22   b  disposed at both ends of the branch conveyer  22  may be rotatably fixed to the bracket and the fixing member (not shown). As such, the fore end of the branch conveyer  22  may function as a rotation shaft. 
     A second pulley  22   b  disposed at the rear end of the branch conveyer  22  may be coupled to one end of the cylinder rod  24   b . As such, when the conveyer rotating member  24  is driven, the branch conveyer  22  may be selectively rotated in a predetermined forward direction or a reverse direction opposite to the forward direction based on the fore end depending on the movement direction of the cylinder rod  24   b.    
     As shown in  FIG. 2 , in order to guide the film product F to the first branch path P 1 , the conveyer rotating member  24  may lower the rear end of the branch conveyer  22  to a predetermined first reference height H 1  by rotating the branch conveyer  22  in any one direction (a clockwise direction in  FIG. 2 ) of predetermined forward and reverse directions to cause the rear end of the branch conveyer  22  to be contact with the fore end of the first discharging unit  30 . The first reference height H 1  may be determined to accommodate the film product F passing through the rear end of the branch conveyer  22  at the fore end of the first discharging unit  30 . For example, as shown in  FIG. 2 , the first reference height H 1  may be determined to level the branch conveyer  22  with a ground G by positioning the fore end of the branch conveyer  22  at the same height as the rear end thereof. 
     As shown in  FIG. 3 , in order to guide the film product F to the second branch path P 2 , the conveyer rotating member  24  may raise the rear end of the branch conveyer  22  to a predetermined second reference height H 2  by rotating the branch conveyer  22  in any one direction (a counterclockwise direction in  FIG. 2 ) opposite to the above direction of predetermined forward and reverse directions to cause the rear end of the branch conveyer  22  to be in contact with the fore end of the second discharging unit  50 . The second reference height H 2  may be determined to accommodate the film product F passing through the rear end of the branch conveyer  22  at the fore end of the second discharging unit  50 . For example, the second reference height H 2  may be determined to incline the branch conveyer  22  upward at the same inclination angle as a first bypass conveyor  53  of the second discharging unit  50 , which will be described later, by positioning the rear of the branch conveyer  22  higher than the fore end by the reference distance. 
     The branch unit  20  may selectively guide the film product F supplied from the supply unit  10  to any one branch path of the first branch path P 1  and the second branch path P 2  through the branch conveyer  22  and the conveyer rotating member  24 . 
     Then, as shown in  FIG. 1 , the first discharging unit  30  may further include a first discharging conveyer  32  that receives the film product F guided to the first branch path P 1  by the branch conveyer  22  and discharges the film product F along the first branch path P 1 . The fore end of the first discharging conveyer  32  may be disposed in contact with the rear end of the branch conveyer  22  positioned at the first reference height H 1  to accommodate the film product F guided to the first branch path P 1  by the branch conveyer  22 . 
     Then, the first loading unit  40  may be provided to load and transfer the film product F. For example, the first loading unit  40  may have the same or similar structure to a load bogie that is commonly used to load and transfer the film product F. In this case, as shown in  FIG. 1 , the first loading unit  40  may include a first support frame  42  having a bottom surface on which a plurality of first wheels  44  is installed to move the corresponding first loading unit  40  along the ground G, and a first loading tray  46  installed at an upper end of the first support frame  42  to load the film product F discharged from the rear end of the first discharging conveyer  32  on an upper surface. The first loading unit  40  may be disposed to cause the fore end to be in contact with the rear end of the first discharging conveyer  32  so as to load the film product F discharged from the first discharging conveyer  32  on the first loading tray  46 . As such, film products F discharged from the first discharging conveyer  32  may be sequentially loaded on the first loading tray  46 . 
     Then, as shown in  FIG. 1 , the second discharging unit  50  may include a bypass member  51  for bypassing and transferring the film product F guided to the second branch path P 2  by the branch conveyer  22  in a state of being spaced apart from the first loading unit  40  by a predetermined interval, and a second discharging conveyer  52  for discharging the film product F bypassed by the bypass member  51  along the second branch path P 2  and loading the film product F on the second loading unit  60 . 
     In general, when the film products discharged from the conveyer are disorderly loaded on the loading tray, there is a risk of the film products being damaged such as by being pushed or folded during a process of loading the film products on the loading tray and the quality of the film products is degraded. To overcome this, as shown in  FIG. 1 , after at least one of workers W 1  and W 2  are positioned at each of the loading units  40  and  60 , a film alignment operation of aligning the film products F by the workers W 1  and W 2  to load the film products F on the loading trays  46  and  66  in a predetermined alignment form may be performed. 
     However, when the discharging units  30  and  50  and the film products F transferred by the discharging units  30  and  50  come into contact with the workers W 1  and W 2  who perform the film alignment operation at the loading units  40  and  60 , there is a risk of the workers W 1  and W 2  being injured or the discharging units  30  and  50  and the film products F being damaged. To overcome this, as shown in  FIG. 1 , the second discharging unit  50  may include the bypass member  51  for bypassing the film product F guided to the second branch path P 2  by the branch conveyer  22  to an upper space of the first loading unit  40  in the state of being spaced apart from the first loading unit  40  and the workers W 1  who perform the alignment operation at the first loading unit  40  by a predetermined distance or greater. Here, the upper space of the first loading unit  40  may be a predetermined empty space positioned above the first loading unit  40  and the workers W 1  without being limited thereto. 
     The configuration of the bypass member  51  is not particularly limited. For example, the bypass member  51  may include the first bypass conveyor  53  for raising the film product F guided to the second branch path P 2  by the branch conveyer  22  to the upper space of the first loading unit  40 , a second bypass conveyer  54  for transferring the film product F raised to the upper space of the first loading unit  40  by the first bypass conveyor  53  to pass through the upper space of the first loading unit  40  in the state in which the first loading unit  40  and the workers W 1  are not in contact with each other, and a third bypass conveyer  55  for lowering the film product F passing through the upper space of the first loading unit  40  by the second bypass conveyer  54  to a height at which the second discharging conveyer  52  is installed. 
     As shown in  FIG. 1 , the first bypass conveyor  53  may be installed to be inclined upward by a predetermined inclination angle to raise the film product F guided to the second branch path P 2  by the branch conveyer  22  to the upper space of the first loading unit  40  in the state of being spaced apart from the first loading unit  40  and the workers W 1  by a predetermined distance or greater. 
     A fore end of the first bypass conveyor  53  may be positioned in contact with the rear end of the branch conveyer  22  positioned at the second reference height H 2  to accommodate the film product F guided to the second branch path P 2  by the branch conveyer  22 . In response thereto, a rear end of the second bypass conveyer  54  may be positioned in the upper space of the first loading unit  40 . In particular, the rear end of the second bypass conveyer  54  may be positioned at a third reference height H 3  that is higher than the first loading unit  40  and the workers W 1  by a predetermined height. 
     The first bypass conveyor  53  may stably raise the film product F transferred from the branch unit  20  to the upper space of the first loading unit  40  in the state in which the first loading unit  40  and the workers W 1  are not in contact with each other. 
     The first bypass conveyor  53  may be installed to be inclined upward, and thus a slip occurs between the film product F and the first bypass conveyor  53  due to gravity when the film product F is raised by the first bypass conveyor  53 , and thus there is a risk of the film product F being disorderly transferred. To overcome this, the second discharging unit  50  may further include a first contact member  56  provided to constantly transfer the film product F in the state of being in close contact with the first bypass conveyor  53 . 
     The configuration of the first contact member  56  is not particularly limited. For example, the first contact member  56  may further include at least one of a first suction unit  56   a  for vacuum-absorbing the film product F in close contact with the first bypass conveyor  53 , or a first touch roll  56   b  for pressurizing the film product F towards the first bypass conveyor  53  in close contact with the first bypass conveyor  53 . 
     As shown in  FIG. 3 , the first suction unit  56   a  may be installed in the first bypass conveyor  53  to face an internal surface of a conveyer belt  53   a  of the first bypass conveyor  53 . The conveyer belt  53   a  may include a plurality of suction holes (not shown) formed therethrough to apply vacuum pressure transferred from the first suction unit  56   a . Thus, the film product F may pass through the first bypass conveyor  53  in close contact with an external surface of the conveyer belt  53   a  by being vacuum-absorbed by vacuum pressure applied to the suction holes. 
     As shown in  FIG. 4 , the first touch roll  56   b  may be installed outside the first bypass conveyor  53  to face the external surface of the conveyer belt  53   a . The first touch roll  56   b  may be transferred by a first roll transferring member  56   c  close to the external surface of the conveyer belt  53   a  or away from the external surface of the conveyer belt  53   a.    
     The configuration of the first roll transferring member  56   c  is not particularly limited. For example, as shown in  FIG. 4 , the first roll transferring member  56   c  may be configured as a cylinder device. In this case, the first roll transferring member  56   c  may include a cylinder body  56   d  fixedly installed to a bracket or other fixing members (not shown), and a cylinder rod  56   e  that reciprocates linearly within a predetermined stroke range by the cylinder body  56   d  and has one end coupled to the first touch roll  56   b . When the first roll transferring member  56   c  is used, the first touch roll  56   b  may pressurize the film product F passing through the corresponding first touch roll  56   b  and the external surface of the conveyer belt  53   a  towards the external surface of the conveyer belt  53   a  in the state of being spaced apart from the external surface of the conveyer belt  53   a  by a predetermined distance corresponding to the thickness of the film product F. Thus, the film product F may pass through the first bypass conveyor  53  in the state of being in close contact with the external surface of the conveyer belt  53   a  by the pressurization force applied from the first touch roll  56   b.    
     As shown in  FIG. 1 , the second bypass conveyer  54  may be installed in the upper space of the first loading unit  40  to cause the film product F passing through the first bypass conveyor  53  to pass through the upper space of the first loading unit  40  in the state of being spaced apart from the first loading unit  40  and the workers W 1  by a predetermined distance or greater. In particular, the second bypass conveyer  54  may be installed to extend in a horizontal direction at the third reference height H 3  to be positioned at the same height as the rear end of the second bypass conveyer  54 , but the present invention is not limited thereto. 
     A fore end of the second bypass conveyer  54  may be disposed in contact with a rear end of the first bypass conveyor  53  to accommodate the film product F passing through the first bypass conveyor  53 . In response thereto, a rear end of the second bypass conveyer  54  may be positioned closer to the second loading unit  60  than the first loading unit  40  and the workers W 1 . 
     The second bypass conveyer  54  may pass through the upper space of the first loading unit  40  in the state in which the film product F transferred from the first bypass conveyor  53  is not in contact with the first loading unit  40  and the workers W 1 . 
     As shown in  FIG. 1 , the third bypass conveyer  55  may be installed to be inclined downward by a predetermined inclination angle to lower the film product F passing through the second bypass conveyer  54  to an installation height of the second discharging conveyer  52  in the state of being spaced apart from the first loading unit  40  and the workers W 1  by a predetermined distance or greater. 
     A fore end of the third bypass conveyer  55  may be positioned in contact with a rear end of the second bypass conveyer  54  to accommodate the film product F passing through the second bypass conveyer  54 . In response thereto, the rear end of the third bypass conveyer  55  may be positioned close to the fore end of the second discharging conveyer  52 . 
     The third bypass conveyer  55  may transfer the film product F transferred from the second discharging conveyer  52  to the second discharging conveyer  52  in the state in which the first loading unit  40  and the workers W 1  are not in contact with each other. 
     The third bypass conveyer  55  may be installed to be inclined downward, and thus a slip occurs between the film product F and the third bypass conveyer  55  due to gravity when the film product F is lowered by the third bypass conveyer  55 , and thus there is a risk of the film product F being disorderly transferred. To overcome this, the second discharging unit  50  may further include a second contact member  57  for causing the film product F to be in close contact with the third bypass conveyer  55 . 
     The second contact member  57  may be provided to constantly transfer the film product F in the state in which the film product F is in close contact with the third bypass conveyer  55 . For example, as shown in  FIGS. 5 and 6 , the second contact member  57  may further include at least one of a second suction unit  57   a  for vacuum-absorbing the film product F in close contact with the third bypass conveyer  55 , or a second touch roll  57   b  for pressurizing the film product F towards the third bypass conveyer  55  in close contact with the third bypass conveyer  55 . 
     As shown in  FIG. 5 , the second suction unit  57   a  may be installed in the third bypass conveyer  55  to face an internal surface of a conveyer belt  55   a  of the third bypass conveyer  55 . The conveyer belt  55   a  may include a plurality of suction holes (not shown) formed therethrough to apply vacuum pressure transferred from the second suction unit  57   a . Thus, the film product F may pass through the third bypass conveyer  55  in close contact with an external surface of the conveyer belt  55   a  by being vacuum-absorbed by vacuum pressure applied to the suction holes. 
     As shown in  FIG. 6 , the second touch roll  57   b  may be installed outside the third bypass conveyer  55  to face the external surface of the conveyer belt  55   a . The second touch roll  57   b  may be transferred by a second roll transferring member  57   c  close to the external surface of the conveyer belt  55   a  or away from the external surface of the conveyer belt  55   a.    
     The configuration of the second roll transferring member  57   c  is not particularly limited. For example, as shown in  FIG. 6 , the second roll transferring member  57   c  may be configured as a cylinder device. In this case, the second roll transferring member  57   c  may include a cylinder body  57   d  fixedly installed to a bracket or other fixing members (not shown), and a cylinder rod  57   e  that reciprocates linearly within a predetermined stroke range by the cylinder body  57   d  and has one end coupled to the second touch roll  57   b . When the second roll transferring member  57   c  is used, the second touch roll  57   b  may pressurize the film product F passing between the corresponding second touch roll  57   b  and the external surface of the conveyer belt  55   a  towards the external surface of the conveyer belt  55   a  in the state of being spaced apart from the external surface of the conveyer belt  55   a  by a predetermined distance corresponding to the thickness of the film product F. Thus, the film product F may pass through the third bypass conveyer  55  in the state of being in close contact with the external surface of the conveyer belt  55   a  by the pressurization force applied from the second touch roll  57   b.    
     As shown in  FIG. 1 , the fore end of the second discharging conveyer  52  may be positioned in contact with the rear end of the third bypass conveyer  55  to accommodate the film product F passing through the third bypass conveyer  55 . The second discharging conveyer  52  may be installed at the same height as the first discharging conveyer  32 , but the present invention is not limited thereto. 
     Then, the second loading unit  60  may be provided to load and transfer the film product F. For example, the second loading unit  60  may have the same or similar structure to a load bogie that is commonly used to load and transfer the film product F. In this case, the second loading unit  60  may include a second support frame  62  having a bottom surface on which a plurality of second wheels  64  is installed to move the corresponding second loading unit  60  along the ground G, and a second loading tray  66  installed at an upper end of the second support frame  62  to load the film product F discharged from the second discharging conveyer  52 . The second loading unit  60  may be installed to cause the fore end to be in contact with the rear end of the second discharging conveyer  52  to load the film product F discharged from the rear end of the second discharging conveyer  52  on the upper surface of the second loading tray  66 . As such, the film products F discharged from the second discharging conveyer  52  may be sequentially loaded on the second loading tray  66 . 
       FIG. 7  is a diagram for explaining a method of discharging a film product along a predetermined first branch path using the branch unit shown in  FIG. 1 .  FIG. 8  is a diagram for explaining a method of discharging a film product along a predetermined second branch path using the branch unit shown in  FIG. 1 . 
     Hereinafter, a method of selectively loading the film products F, which are manufactured in a predetermined processing form by a film manufacturing system, on any one of the first loading unit  40  and the second loading unit  60  and collecting the film products F using the film discharging device  1  will be described with reference to the drawings. 
     First, when the film products F are loaded on the second loading unit  60  by a predetermined film loading limit or greater and there is an available space for additionally loading the film products F in the first loading unit  40 , the workers W 2  who perform the film alignment operation in the second loading unit  60  may transfer the second loading unit  60  to a predetermined collection position and may then collect the film products F from the second loading tray  66  to empty the second loading tray  66 , as shown in  FIG. 7 . As shown in  FIG. 7 , the workers W 1  who perform the film alignment operation in the first loading unit  40  may control the branch unit  20  to guide the film product F to the first branch path P 1  and to transfer the film product F to the first discharging unit  30  and may then sequentially load the film products F discharged from the first discharging conveyer  32  on the first loading tray  46  in a predetermined alignment form. 
     Then, when the film products F are loaded on the first loading unit  40  by a predetermined film loading limit or greater and there is an available space for additionally loading the film products F in the second loading unit  60 , the workers W 1  who perform the film alignment operation in the first loading unit  40  may transfer the first loading unit  40  to a predetermined collection position and may then collect the film products F from the first loading tray  46  to empty the first loading tray  46 , as shown in  FIG. 8 . As shown in  FIG. 8 , the workers W 2  who perform the film alignment operation in the second loading unit  60  may control the branch unit  20  to guide the film product F to the second branch path P 2  and to transfer the film product F to the second discharging unit  50  and may then sequentially load the film products F discharged from the second discharging conveyer  52  on the second loading tray  66  in a predetermined alignment form. 
     As described above, the film discharging device  1  may selectively load the film products F on any one of the pair of loading units  40  and  60  by alternately using the pair of discharging units  30  and  50 . When the film discharging device  1  is used, even if the film product F is collected from any one of the loading units  40  and  60 , on which the film product F is loaded by a predetermined film loading limit or greater, the film product F may be continuously loaded on the other of the loading units  40  and  60 . When the film discharging device  1  is used, a processing process of a film fabric may be continuously performed without interrupting the processing process in order to empty the loading units  40  and  60 , thereby improving the productivity of the film product F.
