1. First embodiment:
(1) Specific example of manufacturing system including trimming apparatus:
FIG. 1 is a diagram for explaining the configuration of a molded article manufacturing system SY1. The molded article manufacturing system SY1 illustrated in FIG. 1 includes the portions represented by SE1 to SE7, and manufactures a predetermined number of molded articles PR1 for each shot from a moldable unformed sheet SHb.

  In FIG. 1, the direction from left to right is a predetermined sheet conveyance direction D1, the left side is the upstream side of the sheets SHb, SHa, and SHs, and the right side is the downstream side of the sheets SHb, SHa, and SHs. The conveyance direction D1, the width direction D2, and the up-down direction are orthogonal to each other, but a case where they intersect without being orthogonal is also included in the present technology.

  The sheet feeding unit SE1 unrolls the roll SH0 wound with the continuously connected unformed sheet SHb. As the unformed sheet SHb, a resin sheet such as a thermoplastic resin sheet, a thermoplastic sheet other than a resin exhibiting thermoplasticity, a formable sheet such as paper, or the like can be used. The resin sheet may be a resin sheet made only of a resin such as a thermoplastic resin, or a sheet made of a material obtained by adding an additive such as a filler to a resin, or a single layer sheet or a laminated sheet obtained by laminating different materials. Good. Polyethylene, polypropylene or the like can be used as the material of the unformed sheet SHb. The unformed sheet SHb may be in the form of a sheet or a film, and may be wound in a roll or may be cut into a predetermined length. The thickness of the sheet can be various thicknesses such as about 1 to 2 mm, about 0.25 to 1 mm, etc. A thick sheet of about 3 mm or more or a film of about 0.25 mm or less may be used. . The molded articles PR1 formed from the unformed sheet SHb include containers such as food containers, components such as inner boxes of home appliances, operation panels, and the like.

  Forming conveyance means 78 installed from heating unit SE2 to forming unit SE3 holds both edges of sheets SHb and SHa, and conveys sheets SHb and SHa in the sheet conveyance direction D1. The sheets SHb and SHa connected in the transport direction D1 are intermittently transported according to the control of the control panel 100 of the control unit SE7. The control panel 100 functions as a control unit of the present invention.

  The heating unit SE2 has a heater group HG in which a plurality of heaters facing the unformed sheet SHb are arranged, and, for example, performs radiation heating at a temperature that softens in a range not melting the unformed sheet SHb. The heater group HG is disposed on the upper side and the lower side of the unformed sheet SHb in the heating unit SE2 illustrated in FIG. 1, but one of them may be omitted.

  In the forming part SE3, a forming die provided under the upper table (not shown) moves up and down between the separated position and the close position, and a clamp (opposed type) provided on the lower table (not shown) with the separated position By moving up and down between the close positions, the unformed sheet SHb is formed. The forming of the unformed sheet SHb may be, besides vacuum forming, differential pressure forming such as pressure forming or pressure air forming, press forming, forming other than thermoforming, or the like. Thermoforming includes differential pressure molding and press molding. Each mold is a female mold that is recessed upward, but may be a male mold that is convex downward or a mold that has an uneven surface. Also, the mold may be disposed on the lower side and the clamp may be disposed on the upper side.

  When the forming portion SE3 separates the forming die and the clamp, the formed sheet SHa is carried out of the forming portion SE3 in a state of being connected to the unformed sheet SHb and guided to the sheet guide 20 via the buffer zone Z1. At this time, the unshot sheet SHb of the next shot is carried into the forming unit SE3. In this manner, the manufacturing system SY1 intermittently conveys the heated unformed sheet SHb intermittently in units of shots in the conveying direction D1 and repeats forming at the time of stopping.

The transport means 10 carries the formed sheet SHa guided by the sheet guide 20 into the trimming section SE4. The trimming device 1 positioned in the trimming portion SE4 is configured such that the upper punching die is lowered when the molding sheet SHa for one shot is carried in a state in which both the cutting dies (upper punching die 43 and lower punching die 44 described later) are separated. It is lowered so as to be close to the punching die, and the molded sheet SHa in the movement stop is cut. When trimming device 1 is moved away both trimming die by raising the upper trimming die is carried out to the scrap collecting portion SE5 through a trimming device present body or we exit sheet guide 20B in a state where scrap sheet SHs is led to the molded sheet SHa Each molded product PR1 is carried out, for example, from below the lower punching die 44 by a molded product carrying out mechanism (not shown) and carried into the product takeout portion SE6. At this time, the formed sheet SHa of the next shot is carried into the main body of the trimming device 1. In this manner, the manufacturing system SY1 repeats conveying the sheets SHa and SHs intermittently in units of shots in the conveyance direction D1 and trimming the formed sheet SHa when stopped.

Is also described as the outlet side feed mechanism 13, 14.

Inlet side feed mechanism 11 and 12, as shown in FIG. 4, are arranged on the right and left of the inlet sheet guide 20 A when viewing the downstream side from the upstream side in the transport direction D1. In the present embodiment, the inlet side feeding mechanisms 11 and 12 function as a first feeding mechanism and a second feeding mechanism. The guide positions L1 and L2 are also collectively referred to as a guide position Lg.
The outlet side feeding mechanisms 13 and 14 are respectively disposed on the left and right of the outlet sheet guide 20B when looking from the upstream side to the downstream side in the transport direction D1. In other words, as shown in FIG. 3, the outlet side feeding mechanisms 13 and 14 are located on the downstream side of the transport path as compared with the inlet side feeding mechanisms 11 and 12. In the present embodiment, the outlet side feeding mechanisms 13 and 14 function as a third feeding mechanism and a fourth feeding mechanism.

  The inlet sheet guide 20A is disposed at the upstream guide position L1 adjacent to the trimming portion SE4, and guides the formed sheet SHa in the transport direction D1 from the guide position L1 toward the trimming position Lt. The entrance sheet guide 20A includes a lower sheet guide 21 disposed below the formed sheet SHa, an upper sheet guide 22 disposed above the formed sheet SHa, and a bridging member 24 whose longitudinal direction is in the sheet width direction D2. ing. The lower sheet guide 21 includes a plurality of guide pieces 21a disposed along the sheet conveyance direction D1, and a support portion 21b supported by the bridging member 24 to support the respective guide pieces 21a.

The upper sheet guide 22 includes a plurality of guide pieces 22a disposed along the sheet conveyance direction D1, and a support 22b supported by the bridging member 24 to support the guide pieces 22a. Each of the guide pieces 22a is disposed at a position where the upstream end is bent upward and faces the lower guide piece 21a.

  The exit sheet guide 20B is disposed at the downstream guiding position L2 adjacent to the trimming portion SE4, and guides the scrap sheet SHs in the transport direction D1 from the trimming position Lt to the guiding position L2. The outlet sheet guide 20B is supported by the plurality of guide pieces 23a arranged along the sheet conveying direction D1 under the scrap sheet SHs, the bridging member 25 whose longitudinal direction is in the sheet width direction D2, and the bridging member 25 A support portion 23b is provided to support each guide piece 23a. The downstream end of each guide piece 23a is bent downward.

  The lifting mechanism 30 lifts and lowers the sheet guide 20 and the feeding mechanisms 11 to 14 in synchronization with the trimming operation of the trimming unit SE4 according to the control of the control panel 100. The lifting mechanism 30 is a first lifting mechanism 31 for supporting and moving the bridging member 24 up and down from the entrance side guiding position L1 to one side D2a outside the forming sheet SHa in the width direction, the width direction outside of the forming sheet SHa from the entrance side guiding position L1.

A mechanism 33 includes a fourth lifting mechanism 34 for supporting and lifting the other end of the bridging member 25 from the exit side guiding position L2 to the other side D2b outside the width direction of the formed sheet SHa.

  In addition, "the width direction outer side of a sheet" is not a term that refers to a direction, but a term that refers to a place. For example, in FIG. 4, one widthwise outer side D2a means a place from the upper edge SHe in FIG. 4 of the sheet to the upper side in FIG. 4 and a range along the upper edge SHe in FIG. Means a place that has Further, in FIG. 4, the other widthwise outer side D2b means a place located on the lower side in FIG. 4 from the lower edge SHe in FIG. 4 of the sheet, and to the lower edge SHe in FIG.

The fourth lifting mechanism 34 has a lifting servomotor M4 fixed to a post 94 on the other end D2b of the trimming section SE4 on the outlet side and outside in the width direction of the scrap sheet SHs, and the power of the motor M4 To drive.

  For example, in the case where the molded sheet has a convex molded product upward and a positioning alignment mold on which the molded product is placed is provided in the trimming portion, to place the molded product on the male mold, After raising the sheet guide, it is necessary to feed the sheet one shot to lower the sheet guide. When the formed sheet has a downwardly convex formed article and a positioning female mold for accommodating the molded article is provided in the trimming portion, the sheet guide is raised to accommodate the molded article in the female mold. Then, it is necessary to feed the sheet for one shot to lower the sheet guide. Even if the trimming section does not have a male type or female type, in order to prevent the sheet from being scratched, the sheet guide is raised and then the sheet is fed by one shot to lower the sheet guide Is good. Hereinafter, an operation of moving up and down the sheet guide 20 and the feeding mechanisms 11 to 14 by the lifting mechanism 30 will also be referred to as “a tilting operation”.

  FIG. 5 is a cross-sectional view for explaining the configuration of the trimming mechanism 40. As shown in FIG. The trimming mechanism 40 includes an upper table 41, a lower table 42, an upper punching die 43, a lower punching die 44, and a table driving mechanism 48. The upper table 41 is raised and lowered between the set apart position and the close position by the table drive mechanism 48. As a result, the replaceable upper punching die 43 provided under the upper table 41 moves up and down between the separated position L21 and the close position L23. When the lower table 42 is fixed, the replaceable lower punches 44 provided on the lower table 42 do not move from the fixed position L22. The punches 43 and 44 constitute cutting means for cutting the molded sheet SHa around the molded product PR1. The table drive mechanism 48 drives one of the tables 41 and 42 using a motor (a servomotor M21 for a table drive mechanism described later) as a power source. For example, a well-known crank mechanism can be used.

  The cutting means may be means for pressing a cutting blade such as a Thomson blade against the receiving member to cut the formed sheet, cutting means for punching the formed sheet by the cutting blade around the mold for positioning the molded product, and the upper and lower blades. It may be a means for punching out a formed sheet by sliding contact or the like.

  On the upper side of the trimming mechanism 40, a knock-out mechanism 50 which can be raised and lowered inside the upper punch 43 is provided. The knockout mechanism 50 includes a knockout rod 51 and a rod drive unit 52. The knockout rod 51 is attached to the rod drive unit 52 so as to penetrate the upper punch die 43 in the vertical direction. The rod drive unit 52 is attached to the upper side of the upper table 41 via a bracket (not shown), and the upper and lower ends of the lower end of the knockout rod 51 are driven according to the drive of a motor (servo motor M31 for knockout mechanism described later). Change the position of the direction. When the lower end of the knockout rod 51 protrudes from the upper punch 43, a so-called knockout operation for separating the molded product PR1 from the upper punch 43 is performed.

  FIG. 6 is a view for explaining the configuration of the product table mechanism 60. As shown in FIG. The product platform mechanism 60 is disposed in the product takeout unit SE6, and includes a count receiving plate 61 and a receiving plate lifting unit 62. The count receiving plate 61 is a pedestal on which the molded product PR1 collected by the molded product unloading mechanism (not shown) is placed. The receiving plate lifting unit 62 is attached to the lower portion of the counting receiving plate 61 and changes the position of the counting receiving plate 61 in the vertical direction. The receiving plate lifting unit 62 is configured of, for example, a ball screw or the like that changes the position of the count receiving plate 61 in the vertical direction according to the driving of a motor (a servomotor M31 for lifting a receiving plate described later).

  As shown in FIGS. 6 (a) and 6 (b), when the molded product PR1 is not placed on the count receiving plate 61, the height of the count receiving plate 61 is the takeout table for taking out the molded product PR1 from the trimming portion SE4. It holds a high position compared to the height of 63. As the molded product PR1 is placed on the count receiving plate 61 by the molded product unloading mechanism, the receiving plate lifting unit 62 sequentially lowers the count receiving plate 61. The descent of the count receiving plate 61 by the receiving plate lifting unit 62 is continued until the height of the count receiving plate 61 becomes equal to the height of the take-out table 63. The number of molded products PR1 placed on the count receiving plate 61 at this time is predetermined and stored by the control panel 100.

  FIG. 7 is a view for explaining a control panel that controls the operations of the feeding mechanisms 11 to 14, the elevating mechanism 30, the table driving mechanism 48, the knockout mechanism 50, and the product table mechanism 60. The control panel 100 shown in FIG. 7 includes a central control circuit 101 that controls the overall operation of the control unit SE7, drive control units 111 to 115 that controls the operation of servomotors, an input I · O 116 to which a sensor 80 is connected, and information output. A unit 131, an operation input unit 132, and the like are provided.

  The central control circuit 101 is a circuit in which a central processing unit (CPU) 102, a read only memory (ROM) 103, a random access memory (RAM) 104, a timer circuit 105, a non-volatile memory 106 and the like are connected to an internal bus. It is assumed. The CPU 102 controls each part of the trimming device 1 while using the RAM 104 as a work area based on a control program stored in the ROM 103 or the non-volatile memory 106.

  The drive control units 111 to 115 control the drive of the servomotor according to the signal from the central control circuit 101. The drive control unit 111 is connected to the elevation servomotors M1 to M4, and individually controls the drive of the elevation servomotors M1 to M4. The drive control unit 112 is connected to the feed mechanism servomotors M11 to M14, and individually controls the drive of the feed mechanism servomotors M11 to M14. The drive control unit 113 is connected to the table drive mechanism servomotor M21, and controls the drive of the table drive mechanism servomotor M21. The drive control unit 114 is connected to the knockout mechanism servomotor M31, and controls the drive of the knockout mechanism servomotor M31. The drive control unit 115 is connected to the receiving plate lifting servomotor M31, and controls the driving of the receiving plate lifting servomotor M41. In this embodiment, the central control circuit 101 can individually control the presence or absence of the output of each of the drive control units 111 to 115 according to the input from the operation input unit 132.

  A sensor 80 is connected to the input I · O 115, and outputs a signal from the sensor 80 to the central control circuit 101. In this embodiment, the sensor 80 has its detection portion attached to the guide piece 22a of the entrance sheet guide 20A so that the formed portion (PR1) of the formed sheet SHa guided by the entrance sheet guide 20A can be detected. It has become. The sensor 80 is configured by, for example, a noncontact infrared sensor or the like.

  The information output unit 131 includes, for example, a display, an audio output device, and a printer, and outputs various information representing the contents of various settings for which an operation input has been received from the user or the operating condition of the trimming device 1 by display. The operation input unit 132 includes, for example, a plurality of buttons such as a cursor button, a number button, and a determination button, and receives an operation input from the user.

(3) How to set the forming sheet:
Next, a method of setting the formed sheet SHa in the guide mechanism 10 of the trimming device 1 will be described. The setting of the formed sheet SHa to the guide mechanism 10 is a step that is required when setting the end of the formed sheet SHa located in the buffer zone Z1 to the trimming device 1 (so-called "heading"). In this embodiment, the feeding operation is completed by feeding the formed sheet SHa to the set position SP by the inlet side feeding mechanisms 11 and 12.

  FIG. 8 is a flow chart for explaining the processing executed by the control panel 100 in the indexing operation of the formed sheet SHa. 9 and 10 are diagrams for explaining the cueing operation of the formed sheet SHa. FIGS. 9A and 10A are views of the inside of the trimming device 1 as viewed from above. FIGS. 9 (b) and 10 (b) are diagrams showing speed changes of the inlet side feeding mechanism 11 and the inlet side feeding mechanism 12. Set position SP shown to FIG. 9A and FIG. 10A is an example, and is not limited to this.

  First, the user inserts the end ST of the formed sheet SHa pulled out of the forming apparatus 200 into the inlet side feeding mechanisms 11 and 12. At this time, the user inserts the end ST of the formed sheet SHa so that the left and right edges of the formed sheet SHa are respectively sandwiched between the drive roller and the driven roller.

  When the insertion of the formed sheet SHa by the user is continued, and the formed portion PR1 of the formed sheet SHa is detected by the sensor 80 attached to the entrance sheet guide 20A (step S11: YES), in step S12, The control panel 100 starts driving the drive rollers of the inlet side feeding mechanisms 11 and 12 in response to a signal from the sensor 80. Therefore, the formed sheet SHa is delivered along the transport direction D1.

  When the user operates the operation input unit 132 to stop the delivery during delivery of the formed sheet SHa by the inlet side feeding mechanisms 11 and 12 (step S13: YES), in step S14, the control panel 100 has the inlet The feed operation of the side feed mechanisms 11, 12 is stopped.

  When the user operates the operation input unit 132 to change the feed speeds of the inlet-side feed mechanisms 11 and 12 (step S15: YES), in step S16, the control board 100 uses the changed feed speed. Send the formed sheet SHa. The control board 100 controls the feed mechanism servomotor M11 for driving the inlet side feed mechanism 11 and the feed mechanism servomotor M12 for driving the inlet side feed mechanism 12 separately. It is possible to adjust the delivery speed V1 and the delivery speed V2 of the inlet side feeding mechanism 12 separately.

  By adjusting the feed speed V1 and the feed speed V2 separately, it is possible to adjust the inclination (θ) of the formed sheet SHa with respect to the conveyance direction D1. As shown in FIG. 9B, when the feed speed V1 and the feed speed V2 are the same, the end ST of the formed sheet SHa is sent in parallel with the center line CL1 along the transport direction D1. On the other hand, as shown in FIG. 10 (b), when the feeding speed V2 is made faster than the feeding speed V1, the leading end ST of the formed sheet SHa is sent out inclined by a predetermined angle θ to the plus side with respect to the center line CL1. It will be. When the feeding speed V2 is made slower than the feeding speed V1, the leading end ST of the formed sheet SHa is sent out with a predetermined angle θ on the negative side with respect to the center line CL1.

  For example, it is assumed that the inclination with respect to the conveyance direction D1 of the upper punching die 43 and the lower punching die 44 is larger than the reference and attached to the upper table 41 or the lower table 42. As in the prior art, when the feed speed of the inlet side feed mechanism 11 and the feed speed of the inlet side feed mechanism 12 can not be adjusted separately, the user is only required to readjust the mounting condition of the upper punch die 43 and the lower punch die 44. There is no way. On the other hand, the user can adjust the feed speed V1 of the inlet side feed mechanism 11 and the feed speed V2 of the inlet side feed mechanism 12 individually, so that the user can adjust the inclination of the upper die 43 and the lower die 44. It is possible to adjust the aspect (for example, the inclination) of the formed sheet SHa to be delivered.

  If the feed amount of the inlet side feed mechanisms 11, 12 has not reached the predetermined feed amount (step S17: NO), the end ST of the formed sheet SHa has not reached the set position SP, so the process returns to step S13. Control board 100 continues processing.

  If the feed amount of the inlet-side feed mechanisms 11, 12 has reached a predetermined feed amount (step S17: YES), the control panel 100 ends the process. In this case, the end ST of the formed sheet SHa has reached the set position SP, and the "heading operation" of the formed sheet SHa is completed.

(4) Synchronous Operation Selection Method Next, a method of selecting a synchronous operation in the trimming apparatus 1 will be described. The user selects the synchronization operation from among the operations performed by the trimming device 1 (the tilting operation, the sending operation, the trimming operation, the knockout operation, the counting operation), and the user selects the synchronization operation by operating the operation input unit 132 It is FIG. 11 is a flow chart for explaining, as an example, a process in which the control panel 100 receives and executes the selection operation of the synchronous operation from the user.

  When the user operates the operation input unit 132 to perform an input for selecting a synchronous operation, in step S21, the control panel 100 displays a synchronous operation selection screen 300 for receiving the selection of the synchronous operation. The synchronization operation selection screen 300 is a UI screen for inputting an operation for selecting an operation to be synchronized by the user.

  FIG. 12 is a diagram showing a synchronous operation selection screen 300 as an example. On the synchronization operation selection screen 300, icons 301 to 305 for selecting an operation to be synchronized are displayed. An icon 301 is an icon for selecting whether or not the trimming operation is to be synchronized. The icon 302 is an icon for selecting whether or not the knockout operation is to be synchronized. An icon 303 is an icon for selecting whether or not the sending operation is to be synchronized. An icon 304 is an icon for selecting whether or not the tilting operation is to be synchronized. An icon 305 is an icon for selecting whether or not the counting operation is to be synchronized.

  In step S22, the control panel 100 receives the selection operation by the user's operation input unit 132. The selection operation is performed, for example, by the user operating the icons 301 to 305 to either “ON” or “OFF”. The icon selected to "ON" is determined by the control panel 100 to be an operation to be synchronized, and the outputs of the drive control units 111 to 115 for driving the servomotor corresponding to this operation are turned on. On the other hand, the icon selected to be "OFF" is determined by the control panel 100 to be an operation to be asynchronous, and the outputs of the drive control units 111 to 115 for driving the servomotor corresponding to this operation are turned off. .

  At step S23, the control panel 100 finalizes the setting of the operation selected at step S22. For example, the process of step S23 is executed by the user operating the icon indicating the confirmation of the selection on the synchronization operation selection screen 300.

  When the control panel 100 does not receive an input indicating return to the home screen by the user (step S24: NO), the control panel 100 maintains the display of the synchronous operation selection screen 300. On the other hand, when the control panel 100 receives an input indicating return to the home screen by the user (step S24: YES), the control panel 100 shifts to the home screen, and ends the process related to the selection of the synchronous operation.

  Next, the operation of the trimming apparatus 1 after the selection of synchronization by the user will be described. FIG. 13 is a diagram showing the timing of each operation when the user selects the synchronization of the trimming operation, the lifting operation, the sending operation, the knockout operation, and the counting operation. In FIG. 14, as an example, the user selects “sending operation”, “trimming operation”, and “knock-out operation” as synchronization targets, and “a tilting operation” and “counting operation” are asynchronous targets. It is a figure which shows the timing of operation | movement.

The operation of the trimming device 1 in the case where all the operations are to be synchronized will be described based on FIG.
As shown in FIG. 13B, when trimming of the formed sheet SHa is started at time t1, the control panel 100 transmits the sheet guide 20 and the feeding mechanism 11 to the raising / lowering mechanism 30 via the drive control unit 111. Make it move up and down. The sheet guide 20 and the feeding mechanisms 11 to 14 are lifted by the tilting operation performed by the lifting mechanism 30.

  Next, as shown in FIGS. 13C and 13D, at time t2, the control panel 100 drives the inlet-side feeding mechanisms 11, 12 and the outlet-side feeding mechanisms 13, 14 via the drive control unit 112. The feed operation is performed. By the delivery operation performed by the inlet-side feeding mechanisms 11 and 12 and the outlet-side feeding mechanisms 13 and 14, the formed sheet SHa is delivered along the transport direction D1, and the portion to be trimmed is positioned at the trimming position Lt.

  Next, as shown in FIG. 13B, the control panel 100 drives the lifting mechanism 30 via the drive control unit 111 to perform the lifting operation (lowering of the formed sheet S) (t3). The forming sheet SHa is lowered by the tilting operation by the elevating mechanism 30 and abuts on the lower punching die 44.

  As shown in FIG. 13A, the upper table 41 of the trimming mechanism 40 continues the crank drive by the control of the servomotor M21 for the table drive mechanism by the drive control unit 113. The position of Z reaches the close position to the lower die 44. Therefore, when the upper punching die 43 and the lower punching die 44 abut, the cutting means trims the trimming target area of the formed sheet S, and the formed product PR1 is separated from the formed sheet S.

  As shown in FIG. 13 (e), after the upper die 43 resumes separation from the lower die 44 (t5), the control panel 100 controls the knockout mechanism 50 via the drive controller 114 to perform the knockout operation. Let it go. By the knockout operation performed by the knockout mechanism 50, the knockout rod 51 is protruded from the upper punch 43 and separates the molded product PR1 from the upper punch 43.

  Then, when the molded product PR1 is recovered by a recovery device (not shown) and the molded product PR1 is placed on the count receiving plate 61, as shown in FIG. 13 (f), the control panel 100 controls the drive control unit 115. The product stand mechanism 60 is caused to perform the counting operation. By the counting operation performed by the product platform mechanism 60, the count receiving plate 61 is lowered by a predetermined amount (t6). The molded sheet SHa from which the molded product PR1 is separated is collected by the collection unit SE5.

  Next, another operation example by the trimming apparatus 1 after selection of synchronization by the user will be described using FIG. In FIG. 14, in the trimming apparatus 1, an operation (delivery operation, trimming operation, knockout operation) in which the user selects synchronization is performed. On the other hand, the trimming apparatus 1 does not perform the counting operation at time t1 to t3 and the counting operation at time t6 because the user has made the operations "setting operation" and "counting operation" asynchronous.

(5) According to the present embodiment as described actions and effects described above, the user, since it is possible to select the operation to synchronize the trimming apparatus 1, the material and destination to be used in the crop unit It becomes possible to correspond flexibly to use.

When setting the formed sheet SHa in the trimming device 1, it is possible to individually adjust the feed amount of the formed sheet SHa separately, so that the set amount of the formed sheet SHa is adjusted according to the installation condition such as the inclination of the die. It is possible to adjust the aspect.
In addition, by setting the feeding mechanism as a separate feeding mechanism of the inlet side feeding mechanism in the path of the forming sheet and the outlet side feeding mechanism, the forming sheet SHa is set by the inlet side feeding mechanism at the time of setting the forming sheet SHa. It is possible to send to the position, and the feeding method can be adjusted more flexibly.
