A large number of horizontally extending arms 98 are fixed to 7, and suction cups 99 for vacuum suction are attached to both ends of these arms 98.

In the above configuration, the plate material 101 is sent to the press machine 10,
A case of press working for high-mix, low-volume production will be explained. As mentioned above, the plate material 101 is loaded on the loading section 80, and the third feeding device 90 transports the plate material 101 to the second feeding device 5.
Sent to 0. Specifically, the rod 93a is extended by driving the air cylinder 93, and the slide table 94 is horizontally moved from a position directly above the second feeding device 50 to a position directly above the loading section 80 along the rail 91a. next,
An air cylinder 95 fixed to the slide table 94 is driven to extend the rod 95a and lower the elevator table 97. Of the loaded plates 101, those containing soil are sucked by nine suction cups. Next, the rod 95a of the air cylinder 95 is retracted to lift the plate material 101. next,
The rod 93a of the air cylinder 93 is compressed, and the plate material 101
is horizontally moved from a position directly above the loading section 80 to a position directly above the second feeding device 50. Next, the rod 95a of the air cylinder 95 is extended to lower the plate material 101.

The plate material 101 is lowered and the support base 61 of the chuck mechanism 60
When placed on the end on the press machine 10 side and on each of the two surfaces 61c, 71c of the support bases 71 of the two sets of guide mechanisms 70, the suction state on the suction cup 99 is released. After this, the rod 95a of the air cylinder 95 is retracted again, and the lifting platform 97 is raised. Note that the plate material 101 is guided by a guide (a number of tapered rubber rollers 79 70) and is reliably placed in a proper position.

After the plate material 101 is placed on the support stand 61.71, the lock 2a of the air cylinder 62 of the chuck 16o is extended and the link 65 is rotated. Then, the shaft 63 rotates following this, and the pair of attachment members 66 rotate, and the presser member 69 fixed to this attachment member 66 rotates.
The sharp tips of the plates press the two corners of the plate material 101 on the uncoiler 20 side.

After the plate material 101 is gripped by the chuck mechanism 60 as described above, the motor 31 is started to rotate the boo 955 of the conveyor 51. Note that the clutch 32 connects the motor 31 and the shaft 53 of the second feeder 50 and releases the connection between the waist motor 31 and the shaft 45 of the first feeder 40 . Due to the rotation of the boot IJ55, the upper part of the steel belt 57 is rotated by the press 1jl.
The plate material 101 is moved toward the press machine 10, and accordingly, the plate material 101 is sent toward the press machine 10. During this movement, the plate material 10
1 is firmly gripped by the chuck mechanism 60, and both side edges are regulated by the rubber rollers 79 of the guide mechanism 70, so that no displacement occurs.

When the end of the plate material 101 on the press machine 10 side is placed on the first lower die 13 of the press machine 10, the feeding of the plate material 101 by the conveyor 51 is temporarily stopped, and then the upper die 14 is lowered, This plate material 101 is cut. The cut workpiece is sequentially subjected to pressing operations such as drawing and hole drilling using the lower die 13 and the upper die 14, and is finally taken out from the takeout port 11b.

The press machine 10 performs the sequential conveyance from the first lower mold 13 to the lower mold 13 of the next process and the removal work from the final lower mold 13.
This is done by a robot (not shown) installed at the

The plate material 101 is cut several times by the first lower die 13 and the second die 14 as described above while being intermittently conveyed.

When the last remaining short plate material 101 is placed on the lower mold 13, the chuck mechanism 60 enters the supply port 11a of the press 10 and further approaches the lower mold 13. As shown in FIG. 5, the support stand 61 is connected to the steel belt 57 between the end on the press machine 10 side (the left end in the figure) and the connection point that goes up the rivet 62 to the steel belt 57. Since it is free, this part can be made to protrude from the pulley 56 toward the lower mold 13, and this nib and chuck mechanism 60 can be brought as close as possible to the lower mold 13, and the last remaining short plate material 101 can be It can be placed on the lower mold 13 reliably.

After the last remaining part of the plate material 101 is placed on the lower die 13,
Retract the rod 62a of the air cylinder 62 and press the holding member 6.
9 from the plate material 101, and 5. Release the condition.

After that, by rotating the motor 31 in the reverse direction, the chuck mechanism 60
is returned to the end of the conveyor 61 on the first feeding device 40 side.

Note that after the chuck mechanism 60 is retracted from the lower die 13, the above-mentioned press working is performed.

After the conveyor 51 starts driving and the chuck mechanism 60 returns to its original position, the third feeding device 90
is waiting by transporting the plate material 101 from the loading section 80 to a position directly above the second feeding device 50, and repeats the same operation thereafter.

Next, a case will be described in which the fill material 102 is sent to the press machine 10 and press processing is performed for mass production of a small number of products. The coil material 102 is attached to the mandrel arm 22 of the uncoiler 20.
, and its both sides are supported by supports 23. The end of the coil material 102 is pulled out, inserted between the rollers 27 through the inlet 26a of the housing 2G of the leveler 25, and pulled out through the outlet 26b. Furthermore, it is inserted between the drive roller 43 and the pressing roller 44 through the introduction port 41a of the housing 41 of the second feeding device 40.

The clutch 32 is switched in advance, and the motor 31 is connected to the shaft 45 that supports the drive roller 43.

In this state, when the motor 31 is driven, the drive roller 43
rotates, and the coil material 102 is sent toward the press machine 10. The coil material 102 is pulled out from the uncoiler 20 and is unwound and curled when passing through the leveler 25. The coil material 102 is sent to the press machine 10 while being placed on the upper surfaces 61c and 71c of the supports 61 and 71, and the first lower mold 13
and the upper die 14, and thereafter press-worked in the same manner as in the case of the plate material 101 described above. The coil material 102 is intermittently fed by the intermittent rotation of the drive roller 43, but at this time, the rubber roller 79 of the guide mechanism 70
Since both side edges of the sheet are regulated, the sheet is accurately fed to the lower mold 13 without lateral displacement.

Note that even if the widths of the plate material 101 and the coil material 102 are different, the positions can be adjusted by sliding the pair of mounting members 66 of the chuck mechanism 60 and sliding the roller mechanism 72 of the guide mechanism 70. The plate material 101 can be reliably gripped by the chuck mechanism 60, and both side edges of the plate material 101 and the coil material 102 can be reliably guided by the rubber rollers 79.

This invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, the second feeding device includes a large number of 717-rollers, a chain conveyor placed on both sides of the 7-lead rollers, and a claw attached to the chain of the chain conveyor. It is also possible to feed the material to the press while pushing the edge on the device side. In this case, the upper surface of the 7-ree roller becomes the mounting surface for the plate material and the fill material.

Further, the first feeding device may also be used as a leveler.

Furthermore, the work supply system of the present invention can be used in various types of press machines.

(Effects of the Invention) As explained above, in this invention, it is possible to supply a coil-shaped workpiece for high-volume production of a small number of products and a plate-shaped workpiece for high-mix low-volume production to a press machine using one workpiece supply system. 1) Therefore, less equipment is needed, operating efficiency is high, and there is no need to rearrange the equipment each time the production method is changed, resulting in lower manufacturing costs.
