Description

[Detailed explanation of the idea] The present invention relates to a material supply device for a press.

As shown in FIG. 1, the material supply device 2 to the press 1 feeds the stacked materials 5 placed on the roller conveyor 4 of the loading section 3 to the separating section 6 by driving the roller conveyor 4.

This separating section 6 includes a disk picker that pulls up the uppermost layer material (stack) 7 of the stacked materials 5 with a vacuum cup and sends it out intermittently to the receiving section 8, and a disk picker that pulls up the uppermost layer material (stack) 7 of the stacked materials 5 and sends it out intermittently to the receiving section 8, and a disk picker that raises the stacked materials 5 as the stack amount decreases. and a material lifting device.

Further, the material 7 on the receiving section 8 is intermittently conveyed within the press 1 by a feed bar or the like.

In the material supply device 2 as described above, the stacked material 5
A forklift or a crane is used to place the material on the loading section 3. Therefore, conventionally, the stacked material 5 is placed on the loading section 3 together with a pallet or a trolley for pulling out the fork claws and crane wire. I had left it there.

Therefore, conventionally, pallets and carts are required, and in order to remove these empty pallets and carts from the stacked materials 5 at the separating section 6, the material supply device must be temporarily stopped.

Japanese Patent Publication No. 39-8428 is a technique for solving this problem.

As shown in FIGS. 1c, 11, and 12, the plate of the extrusion conveyor 26 is projected above the horizontal belt conveyor 27, and then one cylinder 146 is actuated to move a large number of protrusions 147 horizontally. It projects upward from between the belts of the belt conveyor 27 and between the plate pieces 24 of the extrusion conveyor 26, lifts up the piles on the plate pieces 24, and then releases the plate pieces 24 from above the horizontal belt conveyor 27, and the cylinder 146
, each protrusion 147 is lowered, and the stack is placed on the horizontal belt conveyor 27.

This conventional configuration is suitable for transferring a relatively lightweight stack (printed paper), and is suitable for transferring a heavy stacked material consisting of a large number of steel plates, which is the problem solved by the present invention. cannot be transferred at all with one cylinder 146.

Therefore, it is conceivable to use two cylinders 146, but if they are used in this way, it will be difficult to operate them in synchronization, and if they are out of synchronization, the height levels of the protrusions 147 will be uneven, and the protrusions There is a risk that the steel plate on 147 may slip and fall, leading to a serious accident.

The present invention proposes a material feeding device for a press that can solve the above problems.
This will be explained based on the diagram.

The present invention is characterized by a loading section 10, and a roller conveyor 13 that is linked to a motor 12 is disposed on a fixed machine frame 11.

A case 14 is arranged below the roller conveyor 13,
This case 14 has a plurality of sheets (in the embodiment, a total of eight sheets, four in the conveyor transport direction and two rows in the width direction) arranged in a grid pattern.

) is provided through the elevating body 15. A stacked material 16 is placed between the upper ends of these elevating bodies 15 that face each other in the width direction.
A support 17 is attached that can support the.

These supports 17 are located between the rollers of the roller conveyor 13, and when the elevating body 15 moves up and down, the roller conveyor conveyance surface 1
It becomes possible to appear and appear on 3a.

Reference numeral 18 denotes a lifting device for the lifting body 15, which includes racks 19 formed on the lifting body 15, pinions 20 that are always engaged with these racks 19, and a pair of rotating shafts 21 in the width direction to which the pinions 20 are fixed. A bevel gear 22 and an interlocking shaft 23 that rotate both rotating shafts 21 synchronously, and the support 17
It is composed of a cylinder device 24 that raises and lowers the cylinder.

Note that instead of the cylinder device 24, for example, a forward/reverse drive motor with a speed reducer may be interlocked and connected to the interlocking shaft 23.

25 indicates a fork (or crane wire).

The stacked materials 16 are placed on the loading section 10 in the following manner.

That is, first, the cylinder device 24 is extended, and the support tool 17 is
is made to protrude upward from the conveying surface 13a as shown by the imaginary line in FIG.

At this time, the elevating body 15 rises together with the support 17, rotates the rotating shaft 21 via the rack 19 and pinion 20,
Since both rotating shafts 21 are synchronously interlocked via the bevel gear 22 and the interlocking shaft 23, all the supports 17 protrude upward by the same amount.

With the supports 17 protruding, the stacked material 16 directly supported by the forks 25 is positioned above the supports 17 as shown by solid lines in FIG.

Next, the forks 25 are lowered to be located between the supports 17, thereby transferring the stacked material 16 from the forks 25 to the supports 17 as shown in phantom lines in FIG.

After the fork 25 is pulled out laterally, the support 17 is lowered by contraction of the cylinder device 24, and the support 17 is retracted from the conveyance surface 13a, so that the stacked material 16 is placed directly on the roller conveyor 13.

Thereafter, the stacked material 16 can be transported to the separating section by driving the motor 12.

As another loading method, the stacked material 1 is
6 is positioned above the roller conveyor 13, and the stacked material 1 on the fork 25 is moved by the rising support 17.
It is also possible to lift 6.

As described above, according to the present invention, since a plurality of cylinder devices 24 are used, the stacked material 16 can be easily transferred onto the roller conveyor 13 even though it is heavy.

Furthermore, since each support 17 is integrally connected by the rack 19 and pinion 20, both cylinder devices 24 can be completely synchronized, and the height levels of each support 17 can always be made the same.

Therefore, the stacked materials 16 on each support 17 will not slip and fall from the top of each support 17.
