Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a side table in a plate material processing machine such as a turret punch press or a shearing machine.

[0002]

[Prior art]

 For example, in a turret punch press, a side table provided with a free bearing on the upper surface is arranged adjacent to the work table, and a plate material protruding from the work table is movably supported by the side table. In addition, this side table is also used as a carry-out path for discharging processed plates and scraps after processing.

[0003]

[Problems to be solved by the device]

 However, in the case of the above-mentioned conventional side table, even if the maintenance is carried out by going around the back side of the turret punch press, the side table blocks the passage for maintenance, which hinders maintenance. There was a problem. Also, when manually aligning the plate materials on the work table, the passages are similarly blocked by the side tables.

An object of the present invention is to easily secure a passage for manual plate alignment and maintenance at a position adjacent to a plate processing machine as needed, and to automatically carry out a processed plate. It is to provide a table.

[0005]

[Means for Solving the Problems]

 The side table of this invention is a side table that is placed adjacent to the work table of a plate processing machine, in which a plurality of free bearings for mounting plates and a plurality of drive rollers are provided on the top frame, and the plate processing of the top frame is performed. The part adjacent to the machine can be folded downward.

[0006]

[Action]

 According to this configuration, by folding down the portion of the top frame adjacent to the plate material processing machine, it is possible to easily secure a passage for maintenance of the plate material by the plate material processing machine and maintenance. Further, by driving the drive roller, it is possible to carry out the processed plate material to the side table. In addition, free bearing enables free support of the plate as an extension of the work table of the plate processing machine.

That is, the half top frame 18b near the carry-out conveyor 17 is supported and fixed to the support column 19, while one end of the half top frame 18a near the turret punch press 1 is half-turned by the rotary shaft 21 of the sprocket 20. It is connected to the top frame 18b. Further, the advancing / retreating rod 23 of the fluid pressure cylinder 22 pivotally supported on a part of the support column 19 is connected to the middle portion of the half ceiling frame 18a, and the half cylinder frame 18a is shown by a solid line by driving the fluid pressure cylinder 22. It can be bent from a horizontal position to a downward vertical position shown by the chain line.

As shown in FIG. 4, a plurality of drive rollers 24 are arranged on the respective half-top frames 18 a and 18 b with their axes oriented in the front-rear direction, and a plurality of drive rollers 24 are provided at respective positions between the drive rollers 24. A free bearing 25 is arranged. The drive roller 24 is driven by a motor 26 provided on a part of the support column 19 as shown in FIG. That is, the rotation of the sprocket 27 on the side of the motor 26 is transmitted to the sprocket 20 on the side of the half-top frame 18b via a chain 28 as shown in FIG. 6, and the rotation thereof is separately supported by a rotary shaft 21 to a pulley 29. Then, it is transmitted to each drive roller 24 on the half top frame 18b side via the belt 30 wound around the pulley 29. Further, the rotation of the pulley 29 is transmitted to each drive roller 24 on the side of the other half ceiling frame 18a via another belt 31 wound around the pulley 29. As shown in FIG. 4, a work detection sensor 32 for detecting the plate material W carried out from the work table 3 is provided on a part of the half-top frame 18b.

The free bearing 25 is provided so as to be retractable from the upper surface of the group of drive rollers 24. That is, as shown in FIG. 8, the free bearing 25 is rotatably held by a base 34 provided on a support frame 33 so as to be lifted and lowered, and the base 34 is configured to be lifted and lowered by an air cylinder 35. There is.

As shown in FIG. 2, the top frame 36 of the front side table 14 also has a half portion 36 a on the side adjacent to the turret punch press 1 and a scrap box, similar to the top frame 18 of the rear side table 15. It is divided into a half portion 36b on the side adjacent to 16. The half top frame 36a near the turret punch press 1 can be bent downward. That is, the half top frame 36b is supported and fixed to the column 37, while one end of the half top frame 36a near the turret punch press 1 is connected to the half top frame 36b by the pivot 38. . Further, the advancing / retreating rod 40 of the fluid pressure cylinder 39 pivotally supported on a part of the support column 37 is connected to the other end of the half ceiling frame 36a, and the half pressure frame 39a is driven to drive the half ceiling frame 36a. Can be bent from the horizontal position shown by the solid line to the downward vertical position shown by the chain line.

As shown in FIG. 4, a plurality of free bearings 41 are arranged on each of the half top frames 36a and 36b of the side table 14. The holding case 42 of these free bearings 41 is seated on a support plate 44 supported by a base 48 of the top frame 36 via a spacer 43 as shown in FIG. A cover plate 45 having a hole 45a through which the free bearing 41 partially projects is superposed on the cover plate 45. As shown in FIG. 4, a switch 46 for driving the folding of the other half ceiling frame 36a is provided at the front end of the half ceiling frame 36b of the front side table 14, and a rear side table 15b is provided. A switch 47 for driving the folding of the other half top frame 18a is provided at the rear end of the other half top frame 18b.

The operation of the above configuration will be described. When the turret punch press 1 is automatically operated, the respective half top frames 18a and 36a of the two side tables 14 and 15 are maintained in the horizontal postures shown by the solid lines in FIGS. The plate material W protruding from the work table 3 of the turret punch press 1 is supported by the two side tables 14 and 15. That is, in the front side table 14, the plate material W is movably supported by the free bearing 41 on the upper surface thereof. Further, on the rear side table 15, the free bearing 25 is elevated to a position protruding from the upper surface of the group of drive rollers 24, and the plate material W is movably supported by the free bearing 25.

The plate material W processed by the turret punch press 1 is carried out from the work table 3 to the rear side table 15 and further carried out to the carry-out conveyor 17 while the carriage 9 and the slide table 3b are moved in the direction. It At this time, the free bearing 25 of the side table 15 is lowered from the upper surface of the group of drive rollers 24 to the position where the drive rollers 24 are retracted, and the plate material W on the side table 15 is fed by the rotation of the drive rollers 24. When the outer diameter punching process is performed on the plate material W, the plate piece, which is the outer diameter punched product, is kept continuous with the rest of the plate material by the micro-projection, and the micro head is finally cut by the sub head 7. However, the plate piece is also carried out to the carry-out conveyor 17 via the side table 15 as described above.

In the case where the turret punch press 1 is turned around to the back side for maintenance or when the work for aligning the plate material W on the work table 3 by hand is provided, it is provided before and after each side table 14, 15. By turning on the switches 46 and 47, the fluid pressure cylinders 22 and 39 are driven, whereby the half-top frames 18a and 36a of the side tables 14 and 15 are moved as shown by the chain lines in FIGS. 1 and 2. Folds down. As a result, a passage is secured to the side of the turret punch press 1 near the side tables 14 and 15, so that the maintenance can be performed and the work of positioning the plate material W can be performed manually.
