More specifically, the present invention relates to a carry-out device and a plate material processing system capable of converting a workpiece conveyed in the left-right direction from the plate material processing machine in a horizontal posture state into, for example, a tilted posture and carrying it forward.

  Conventionally, a processed product processed by a plate processing machine that performs bending processing of a plate-shaped workpiece is carried out in a horizontal state on a carry-out roller conveyor disposed on the front side or one of the left and right sides of the plate processing machine. . And the processed product on the said conveyance roller conveyor is adsorb | sucked by the carrying-out means provided with the vacuum pad, for example, the processed product is carried out on a product pallet (for example, refer patent document 1, 2).

JP 2000-103523 A JP-A-5-69947

  Patent Documents 1 and 2 describe a configuration in which a workpiece in a horizontal state on a carry-out roller conveyor is adsorbed by a vacuum pad provided in a carry-out means and carried onto a pallet. Furthermore, Patent Document 2 describes a configuration in which a processed product is placed in an inclined state on a pallet.

  By the way, there is a case where a workpiece that has been bent by a bending machine cannot be adsorbed by a vacuum pad due to the presence of, for example, a hole or a rising portion that has been bent. In this case, the processed product is transferred onto a carry-out conveyor provided on the side of the bending machine, and the processed product is taken out from the carry-out conveyor. As described above, when the workpiece is taken out from the carry-out conveyor, the workpiece can be brought to one side of the carry-out conveyor by tilting the carry-out conveyor. Therefore, it becomes easy to take out the processed product on one side of the carry-out conveyor.

  By the way, in order to incline the conveyor and bring the processed product to one side, a configuration in which a plurality of free bears are provided on the upper surface of the conveyor is possible. In this case, for example, when receiving the workpiece from the table in the previous process, the workpiece may be rotated (turned) horizontally and inclined with respect to the loading direction. Therefore, there is a problem that a measure for preventing the rotation (tilt) of the processed product is necessary.

  Therefore, instead of the free bear, it is possible to adopt a configuration in which a plurality of rollers are provided on the conveyor. In this case, when receiving the workpiece from the table in the previous process, the roller rotates, so that the inclination with respect to the loading direction can be suppressed and the loading can be easily performed. However, if the conveyor is tilted in the direction perpendicular to the loading direction and the processed product is brought closer to the side of the conveyor, a slip occurs between the roller and the processed product, and the processed product is scratched. There is a problem that may occur.

  The present invention has been made in view of the problems as described above, and is an apparatus for carrying out a processed product from a plate material processing machine, wherein a transfer table capable of supporting the processed product is provided on a table base in a tiltable manner, and the transfer The table frame is provided with a workpiece support member that supports the workpiece that slides forward from the transfer table so as to be movable in the left-right direction when the table is tilted.

  Further, the carry-out device includes a roller that can be moved into and out of the support surface of the transfer table.

  Further, the carry-out device includes a brake mechanism that brakes the workpiece that moves to the inclined lower end side on the inclined lower end side of the transfer table.

  Further, in the unloading device, a workpiece lifting support member that supports a part of the workpiece in a floating state from the support surface of the conveyance table in order to facilitate removal of the workpiece from the conveyance table to the front side. It is provided on the inclined lower end side.

  Further, in the carry-out device, the friction member constituting the brake mechanism is provided so as to be inclined between the workpiece lifting support member and the support surface of the transfer table so that the front side becomes higher.

  In the carry-out device, an opening / closing door device that can be prevented from entering the inclined lower end side of the transfer table is provided on one side of the transfer table.

  Further, in the carry-out device, the opening / closing door device includes a human body detection sensor for detecting intrusion into the inclined lower end side of the transfer table.

  In the carry-out device, the open / close door device is a sliding door.

  Further, in the unloading device, a laser scanner as the human body detection sensor is provided on the front side of the sliding door that is moved to the front side in the opening / closing door device, and a fence is provided on the opposite side of the opening / closing door device with the conveyance table in between. When the sliding door of the open / close door device is in a state of being moved to the front side, it is formed between the protection range of the laser scanner and the fence on the front side of the facing position of the fence facing the laser scanner. An intrusion prevention member for preventing intrusion of a hand or the like from the belt-like space is provided.

  Further, in the carry-out device, the swing regulating member for regulating the swinging of the sliding door in the left-right direction in the opening / closing door device is disposed on both the left and right sides while maintaining a space through which the lower end of the sliding door can pass.

  In addition, on one side of the plate material processing machine for bending plate-shaped workpieces, a support table for horizontally supporting the bent workpiece is provided, and the front side is lowered on the front side of this support table. A table that supports the transfer table is provided with a support table that supports the transfer table, and includes a support roller that supports the work piece that slides down from the transfer table when the transfer table is inclined. It is characterized by this.

  According to the present invention, when the work table on the transport table is inclined toward the front side of the transport table by tilting the transport table, the work product is supported by the work product support member provided on the transport table and slides down. To the front. Then, the slipped workpiece is supported by a workpiece support member that supports the workpiece movably in the left-right direction. Therefore, the workpiece can be easily moved in the left-right direction.

  Further, when the workpiece is slid down from the transfer table, the inclination of the workpiece is suppressed. In addition, it is possible to suppress the occurrence of scratches or the like due to sliding on the processed product.

  Referring to FIG. 1, a plate material processing system 1 according to an embodiment of the present invention includes a plate material processing machine 3 that performs bending processing of a plate-like workpiece W. On the front side (front side in the Y-axis direction) of the plate material processing machine 3, left and right work tables 5 that horizontally support the workpiece W supplied to the plate material processing machine 3 are provided. Further, a manipulator 7 for supplying the workpiece W to the plate material processing machine 3 is provided on the front side of the plate material processing machine 3.

  The plate material processing machine 3 and the manipulator 7 are already well known by, for example, Japanese Patent Application Laid-Open No. 2006-75880. Therefore, a more detailed description of the plate material processing machine 3 and the manipulator 7 will be omitted.

  A guide member 9 that is long in the left-right direction (X-axis direction) is provided on the upper front side of the plate material processing machine 3. The guide member 9 is provided horizontally from an upper position of the work table 5 to an upper position of a support table 11 provided adjacent to the work table 5 in the left-right direction. The guide member 9 is provided with a workpiece carry-in / out device 13 that can reciprocate in the left-right direction.

  The workpiece carry-in / out device 13 supports the function of carrying the workpiece W supplied onto the support table 11 onto the work table 5 and the processed product processed by the plate material processing machine 3 from above the work table 5. It has the function to carry out on the table 11. FIG. The workpiece carry-in / out device 13 may have a configuration in which a plurality of vacuum pads for adsorbing the workpiece W can be moved up and down, or a configuration in which a workpiece clamp that can clamp the edge of the workpiece W can be moved up and down. it can. Furthermore, the workpiece carry-in / out device 13 can be configured to include both a vacuum pad and a workpiece clamp.

  In other words, the work carry-in / out device 13 only needs to have a function for carrying a workpiece W from the support table 11 to the work table 5 and a function for carrying out a workpiece from the work table 5 to the support table 11. . Therefore, as described above, various configurations such as a configuration provided with a vacuum pad, a configuration provided with a work clamp, and a configuration provided with a fork for supporting a workpiece or a processed product from below can be adopted. . In addition, this kind of workpiece carrying-in / out apparatus 13 is a structure already known. Therefore, a more detailed description of the configuration of the work carry-in / out device 13 is omitted.

  The support table 11 has a function of feeding a workpiece carried out from the work table 5 to the front side. The operation of feeding the processed product on the support table 11 to the front side is performed by, for example, a pusher (not shown) provided on the support table 11 so as to be movable back and forth. A transport table 15 is disposed on the front side of the support table 11. Therefore, the support table 11 supports the processed product carried out from the work table 5 in the X-axis direction. And the support table 11 has a function which sends the processed goods carried in on the work table 5 on the said conveyance table 15 of the front side.

  The transport table 15 constitutes a part of the carry-out device 17 according to the present embodiment, and is configured as follows. That is, the transfer device 17 includes a table base 19 as shown in FIG. The transfer table 15 is provided on the table frame 19. As shown in FIG. 4, the transport table 15 is provided so as to be tiltable so that the front side in the Y-axis direction is lowered. That is, the conveyance table 15 is configured to slide down the processed product sent out from the support table 11 to the front side by inclining.

  The transport table 15 is provided with a plurality of workpiece support members 20 that support workpieces so as to be movable in the Y-axis direction. The workpiece support member 20 is composed of a roller (roller roller) that is rotatable about an axis in the X-axis direction. Therefore, the workpiece can be easily moved in the Y-axis direction on the transfer table 15. At this time, since the workpiece support member 20 is a roller, movement (inclination) in a direction intersecting the movement direction is suppressed during movement in the Y-axis direction. In other words, although the workpiece can be easily moved in the Y-axis direction on the conveyance table 15, the rotation (turning) of the workpiece on the conveyance table 15 is suppressed.

  As described above, in order to prevent the workpiece sent out from the support table 11 onto the conveyance table 15 from vigorously jumping out from the front side in the Y-axis direction (the inclined lower end when the conveyance table 15 is inclined), A brake mechanism 21 that brakes the movement of the workpiece is provided on the inclined lower end side (front side in the Y-axis direction) of the transport table 15. That is, as shown in FIG. 5, a friction member 23 such as a friction plate is provided on the upper surface of the transfer table 15 in the Y-axis direction.

  As shown in FIG. 5, the friction member 23 is inclined so that the front side in the Y-axis direction becomes higher when the transport table 15 is in a horizontal state. Therefore, when the processed product sent to the transfer table 15 moves to the front side of the transfer table 15, the front side in the moving direction of the processed product (front side in the Y-axis direction) rides on the friction member 23 and is braked. become. Therefore, the processed product sent out on the transfer table 15 does not jump out from the transfer table 15 to the front side.

  Further, at the front end edge of the transfer table 15, when a relatively small processed product is taken out from the transfer table 15, a part of the processed product is floated from the upper surface (support surface) of the transfer table 15. A workpiece lifting member 25 for lifting and supporting is provided. More specifically, a plurality of roller brackets 27 are erected on the front end edge of the transport table 15 at appropriate intervals in the X-axis direction. Each roller bracket 27 is provided with a roller as an example of the workpiece lifting member 25 so as to be rotatable about an axis in the X-axis direction. The workpiece lifting member 25 is provided higher than the front end edge of the friction member 23 when the transport table 15 is in a horizontal state.

  In other words, the friction member 23 is provided between the workpiece lifting member 25 and the support surface of the transport table 15 so as to be inclined so that the front side becomes higher.

  With the above configuration, when a workpiece is sent from the support table 11 onto the conveying table 15 in a horizontal state, the front side of the workpiece rides on the friction member 23, and the forward movement is stopped. Thereafter, when the processed product is taken out to the front side, the processed product is pulled out to the front side, and the front end side of the processed product is placed on the workpiece lifting member 25. At this time, the front side of the processed product floats from the support surface of the transport table 15 and the friction member 23. Therefore, the front end edge of the processed product can be easily held, and the processed product can be easily pulled out to the front side.

  Therefore, when the processed product is relatively small or light, the operator can easily take out the processed product from the transfer table 15 to the front side.

  By the way, even if the processed product is relatively large and heavy, the processed product on the transfer table 15 can be easily transferred in the left-right direction (X-axis direction). That is, on the front side in the Y-axis direction of the table base 19, a plurality of workpiece support members (support rollers) 29 that support the edge of the workpiece so as to be movable in the X-axis direction are provided at appropriate intervals in the X direction. ing.

  More specifically, as shown in FIG. 3, a roller bracket 31 is provided at the front lower portion of the table base 19 in the Y-axis direction so as to protrude forward. The roller bracket 31 is provided with the support roller (work product support member) 29 so as to be substantially horizontal and rotatable about the axis in the Y-axis direction. The support roller 29 is provided corresponding to a gap 33 (see FIG. 5) in the X-axis direction between the roller brackets 27. As described above, when the transport table 15 is tilted, the lower end edge of the processed product that enters the gap 33 and slides on the transport table 15 is supported as shown in FIG.

  That is, after a relatively large workpiece is sent out onto the transfer table 15, if the front side of the transfer table 15 is tilted so as to be lowered, the friction member 23 is similarly tilted. Therefore, the lower end edge of the processed product sliding down on the transport table 15 is supported by the plurality of support rollers 29. Therefore, the processed product supported by the support roller 29 and the conveyance table 15 can be moved in the left-right direction (X-axis direction).

  Here, the roller control roller 20 provided in the transport table 15 has a function of suppressing the workpiece on the transport table 15 from moving in the X-axis direction. Therefore, it is difficult for the part of the processed product supported by the transfer table 15 to move smoothly in the X-axis direction. Therefore, in the present embodiment, when the front side of the transport table 15 is tilted so as to be lowered, a plurality of parts that can be raised and lowered with respect to the support surface of the transport table 15 (the support surface on which the roller roller 20 supports the workpiece). The rollers 35 (see FIG. 3) are provided at appropriate intervals in the X-axis direction.

  More specifically, as shown in FIG. 7, the transport table 15 is supported on the table base 19 via a pivot 37 in the X-axis direction so as to be tiltable. In order to tilt the transfer table 15 about the pivot 37, the table base 19 is provided with an actuator for tilting operation and a fluid pressure cylinder 39 as an example. The tip of the piston rod 39P in the fluid pressure cylinder 39 is pivotally connected to the transfer table 15 via a hinge pin 41. Accordingly, the transfer table 15 is tilted about the pivot 37 by extending and contracting the piston rod 39P of the fluid pressure cylinder 39.

  The roller 35 is provided so as to protrude from the support surface of the transport table 15 when tilted so that the front side of the transport table 15 in the Y-axis direction is lowered. That is, on the lower surface of the transfer table 15 and on the rear side in the Y-axis direction, as shown in FIG. 7, a girder member 43 that is long in the Y-axis direction substantially parallel to the lower surface of the transfer table 15 is integrally formed. Is provided. The rear end side of the roller base 49 is swingably supported by a bracket 45 provided on the rear end side of the beam member 43 via a pivot 47. The roller 35 is rotatably provided on the upper surface of the roller base 49.

  A slit 51 along the longitudinal direction of the roller base 49 is provided on the front end side of the roller base 47. A roller provided at one end of a bell crank 55 that is swingably supported via a pivot 53 on the front end side of the girder member 43 is movably engaged with the slit 51. The other end of the bell crank 55 is pivotally connected to the tip of a swing rod 57 via a hinge pin 59. The other end of the swing rod 57 is pivotally connected to a bracket 61 provided integrally on the front end side of the table base 19 via a hinge pin 63.

  In the above configuration, as shown in FIG. 7, when the piston rod 39 </ b> P of the fluid pressure cylinder 39 is extended and operated while the roller 35 is immersed in the upper surface of the conveyance table 15, the conveyance table 15 is pivoted 37. Is inclined so that the front end side (the right end portion in FIG. 7) gradually becomes lower. In other words, the conveyance table 15 is inclined so that the rear end side (left end side in FIG. 7) gradually increases.

  When the transport table 15 is gradually inclined as described above, the other end side of the swing rod 57 is relatively pulled. Therefore, the bell crank 55 is rotated clockwise around the pivot 53 by the action of the swing rod 57. When the bell crank 55 rotates as described above, one end side of the bell crank 55 moves in the slit 51 of the roller base 49. Accordingly, the roller base 49 rotates about the pivot 47 so as to rise with respect to the transport table 15.

  Therefore, when the rear end side of the conveyance table 15 rises, the roller 35 protrudes from the conveyance surface of the conveyance table 15 as shown in FIG. Therefore, the support of the workpiece supported on the transport table 15 is switched from the support state by the roller control roller 20 to the support state by the roller 35. That is, when the front end side of the transfer table 15 is inclined so as to be lowered, one end edge (lower end edge) of the processed product supported on the transfer table 15 is supported by the support roller 29. Then, the portion supported by the roller control roller 20 is supported by the roller 35. Therefore, even if the workpiece is large and heavy, the workpiece can be easily moved in the X-axis direction with the workpiece tilted.

  By the way, as shown in FIGS. 1 and 2, fences 65 are arranged on the side of the plate material processing machine 3 in the X-axis direction and on the side of the work table 5 and the support table 11 in the X-axis direction, respectively. . Between the support table 11 and the transport table 15, a fence 67 having a gap through which a processed product can pass is disposed. Further, a fence 69 is disposed on one side of the transfer table 15 in the X-axis direction, and an opening / closing door device 71 is disposed on the other side. Note that the front of the transfer table 15 in the Y-axis direction is closed by a fence or a wall (not shown).

  That is, the periphery of the workpiece machining area and the workpiece movement area is surrounded by the fence 69 and the like, so that safety is ensured.

  By the way, in a state where the front side of the transfer table 15 in the Y axis direction is lowered, the workpiece supported by the transfer table 15 is moved in the left-right direction (X-axis direction), and the opening / closing door device 71 is moved. In order to move to the outside in the left-right direction, the opening / closing door device 71 needs to be opened, and an operator needs to enter the area on the front side of the transfer table 15.

  Therefore, the opening / closing door device 71 is configured as follows. That is, referring to FIGS. 1, 2 and 9, the opening / closing door device 71, as shown in FIGS. 1 and 2, is on the side of the transfer table 15 in the X direction and on the Y axis of the transfer table 15. A retaining wall 73 is provided corresponding to the rear portion of the direction. An upper rail 75 extending horizontally to a position corresponding to the front region is provided on the transport table 15 in the front-rear direction (Y-axis direction) on the upper portion of the retaining wall 73.

  The upper rail 75 is made of, for example, parallel lip groove steel (C-shaped steel), and is provided with an upper runner (not shown) so as to be movable. Then, two interlocking sliding doors 77A and 77B are suspended from the upper runner. In other words, the opening / closing door device 71 is configured as a top hanging sliding door. Therefore, there is no lower rail, and for example, a carriage or the like can be easily brought close to the transfer table 15.

  The sliding door 77A in the open / close door device 71 is provided with a handle 79 for opening and closing the sliding doors 77A and 77B, and for detecting the entry of an operator or the like into the area on the front side of the transfer table 15. For example, a human body detection sensor 81 such as a laser scanner is provided.

  Therefore, for example, when an operator or the like enters the front region of the transfer table 15 during the tilting operation of the transfer table 15 or the opening / closing operation of the opening / closing door device 71, the human body detection sensor 81 detects it. Therefore, when an entry of an operator or the like is detected, necessary safety measures can be taken, such as stopping the tilting operation of the transfer table 15, for example. That is, safety can be improved.

  As understood from the above description, a plurality of roller control rollers 20 are provided on the upper surface of the conveyance table 15 provided on the table base 19 so as to be tiltable. Therefore, when the workpiece is slid down by tilting the transfer table 15, the workpiece does not meander or turn. That is, the processed product slides down (lowers) linearly. Since the processed product and the roller control roller 20 are in rolling contact, the processed product is not scratched.

  Further, the lower end side of the conveying table 15 is provided with a friction member 23 for braking the movement of the workpiece to be slid down. Therefore, when the workpiece is sent onto the conveyance table 15 when the conveyance table 15 is in the horizontal state, the forward movement of the workpiece is braked. Therefore, the processed product does not jump out of the inclined lower end side (front side) of the transfer table 15 vigorously.

  And in the state which hold | maintained the conveyance table 15 horizontally, when taking out a workpiece from the front side (inclination lower end side), the roller 25 with which the front side was equipped, the part of the workpiece was lifted from the upper surface of the conveyance table 15 The state (lifted state) can be maintained. Therefore, it is possible to easily take out the processed product from the front side of the conveyance table 15 in the horizontal state.

  When the front side of the transfer table 15 is inclined so as to be lowered, the lower end edge of the processed product on the transfer table 15 is supported by a support roller 29 provided on the table base 19. When the transport table 15 is tilted, the roller 35 protrudes from the support surface of the transport table 15 to support the processed product. In other words, the support state of the workpiece on the support surface of the transfer table 15 is switched from the support by the roller roller 20 to the support state by the roller 35.

  Therefore, when the workpiece is moved in the left-right direction with the conveyance table 15 tilted, the workpiece can be moved smoothly. Therefore, even if the processed product is large and heavy, it can be easily carried out in the left-right direction.

  In the embodiment, the opening / closing door device 71 is provided on one side of the transfer table 15 in the left-right direction. The open / close door device 71 is provided with a human body detection sensor 81 that detects the entry of an operator or the like into the front region of the transfer table 15. Therefore, for example, the operation of the transfer table 15 can be stopped by the detection operation of the human body detection sensor 81. Therefore, safety can be improved.

  The open / close door device 71 includes sliding doors 77A and 77B. Therefore, the area occupied by the open / close door device 71 can be reduced to save space.

  As already understood, as shown in FIG. 1, a fence 69 is disposed on one side in the left-right direction of the transport table 15 with the transport table 15 in between, and an open / close door on the other side in the left-right direction of the transport table 15. The device 71 is arranged. As shown in FIG. 9, the opening / closing door device 71 includes a human body detection sensor 81 on the front side of a sliding door 77A (a sliding door that can be pulled out to the foremost side) that can be opened and closed in the front-rear direction (Y-axis direction). . Therefore, when the sliding doors 77A and 77B in the opening / closing door device 71 are pulled out and closed, it is possible to detect that an operator or the like enters the front side of the transfer table 15. Therefore, it is possible to improve safety by detecting that the operator or the like has approached the front side of the transfer table 15 by the human body detection sensor 81 and stopping the operation of the transfer table 15 or the like.

  By the way, the laser scanner as the human body detection sensor 81 can arbitrarily adjust the protection range 81A (see FIG. 12) in which the laser beam scans and detects the operator or the like. Therefore, the region of the protection range 81A is set so that the laser scanner 81 does not detect the facing position of the fence 69 facing the human body detection sensor (laser scanner) 81 with the transport table 15 in between. There is a need to.

  In this case, as a characteristic of the laser scanner 81, in order to prevent a detection error, a predetermined space, for example, an interval of 100 mm, that is, a strip-shaped space 91 in the vertical direction is provided between the protection range 81A and the support 69A of the fence 69. is necessary. As described above, if the space 91 has an interval of about 100 mm, there is a possibility that a hand is accidentally inserted from the space 91.

  Therefore, in order to prevent the entry of a hand or the like from the space 91, the support 69A is provided with an appropriately shaped intrusion prevention member 93. Therefore, it is possible to prevent the operator's hand and the like from entering the space 91 between the protection range 81A and the support column 69A in the laser scanner 81, and the safety is further improved.

  The sliding doors 77A and 77B in the open / close door device 71 are suspended from the upper rail 75 in the front-rear direction and moved in the front-rear direction. Accordingly, the lower portions of the sliding doors 77A and 77B are likely to sway in the left-right direction (X-axis direction). Therefore, on the floor on which the lower end of the sliding door 77A passes in the front-rear direction (Y-axis direction), a pair of swing restricting members 95A and 95B as shown in FIG. 13 are provided separately in the left-right direction (X-axis direction). ing. In the present embodiment, the pair of swing restricting members 95A and 95B are provided facing the X-axis direction. However, the swing regulating members 95A and 95B may be arranged so as to be displaced in the Y-axis direction without facing in the X-axis direction.

  The swing restricting members 95A and 95B are provided with vertical swing restricting surfaces 97A and 97B that can contact the side surface in the X-axis direction at the lower end of the sliding door 77A. The interval between the swing restricting surfaces 97A and 97B in the swing restricting members 95A and 95B is such that the lower end of the sliding door 77A can pass freely, and the lower end of the sliding door 77A greatly swings in the left-right direction (X-axis direction). The interval is set to be regulated.

  Further, guide surfaces 99A and 99B inclined in the X-axis direction are provided on both sides of the swing restricting surfaces 97A and 97B in the Y-axis direction so that both sides in the Y-axis direction are gradually widened.
