Description

[Detailed description of the invention] This invention relates to a material supply device for a press machine. Specifically, it is a device that simultaneously supplies multiple blank materials to a press machine, and presses the material between taking out the material and supplying it to the press. It relates to a material supply device that can be adapted to the position of a mold.

Some molds for press machines can process multiple products at the same time, and some feeders that stack blank materials and supply them to the press machine can also supply multiple sheets of material at the same time. However, the distance between the molds and the position of the blank in the supply device are not necessarily at the same position, and in fact, in many cases, the distance between the two does not match.

Among the above-mentioned material supply devices, the lower end of the stacked materials is intermittently raised using a hydraulic cylinder, etc.
With a device that picks up materials in order from the top layer with a vacuum cup and supplies them to a press machine, it is not possible to easily change the stack position and adjust the stack position each time the mold is replaced. Therefore, even when an industrial robot is disposed between a material supply device and a press machine, etc., it is inconvenient that a plurality of sheets of material cannot be supplied at the same time.

The present invention aims to eliminate these conventional inconveniences and provide a device that changes the spacing between blank materials while feeding them into a press machine, and supplies the blank materials to a press die with the spacing matched. .

Next, an embodiment illustrating details of the present invention will be described. The feeder main body 1 adjacent to the press machine is
A movable stack truck 2 is provided. The feeder main body 1 has hydraulic cylinders 3, 3 located below the stack truck 2 and acting upward.
and vacuum cups 4, 4 are provided above the hydraulic cylinders 3, 3 facing the cylinders,
When the stacking truck 2 stacks the blanks and transports them onto the hydraulic cylinders 3, 3, the piston rods 5, 5 of the cylinders are inserted into the holes of the stacking truck 2 to stack the blanks 6, 6 on the truck. Push up and suction the topmost blank with vacuum cups 4 and 4.

The stack truck 2 has three cylinders 3, 3.
And vacuum cups 4 and 4 are installed,
In this explanation, two units on both sides are used to simultaneously supply blank materials 6, 6 from two stacks.

Also, the feeder main body 1 has vacuum cups 4, 4.
A pair of rails 10, 1 extending horizontally below the
0, and rollers 11, 1 are installed on the rails 10, 10.
A pedestal 12 is supported by the main body 1 and moves along a rail, and the pedestal 12 is driven reciprocally by an air cylinder device 13 provided between the main body 1 and the main body 1.

The pedestal 12 has the rail 10 at the center position,
Two elongated guide holes 14, 14 parallel to 10 are formed in the linear direction, and two guide holes 14, 14 with different output direction openings are formed on the lower surface of the pedestal 12 on both sides of the guide holes 14, 14.
Two air cylinders 15, 15 are provided. Then, the claws 17, 17 provided on the piston rods 16, 16 of the air cylinders 15, 15 are inserted into the guide holes 14,
Insert it from inside 14 with it protruding onto the pedestal 2. By doing so, the claw pieces 17, 17 move in the direction toward or away from each other within the guide holes 14, 14.

The present invention has the above configuration, and FIG. 4 shows an example of using the feeding device of the present invention, and the drawing is a plan view, in which the feeding device main body 1 is
The robot 21 is installed on the left side of the main body 1 and moves back and forth between the main body 1 and the press machine 20.
is supplied to the mold 22 of the press machine 20.

Blank materials 6 stacked on the stack truck 2,
6 to the press machine, first, the pedestal 12
is kept away from the lower position of the vacuum cups 4, 4 by the air cylinder device 13, and the hydraulic cylinders 3, 3 are driven to insert the piston rods 5, 5 into the carriage to push up the blank material layer and simultaneously push up the vacuum cups 4, 4. is lowered to adsorb the uppermost blank material 6, 6, and then the hydraulic cylinder 3,
3 and vacuum cups 4, 4 are returned to their original positions.

Thereafter, the pedestal 12 is pulled by the air cylinder device 13 and guided to a position below the vacuum cups 4, 4, and the blank materials 6, 6 that have been adsorbed by the vacuum cups are placed on the pedestal 12. Subsequently, the air cylinder device 13 is operated to move the pedestal 12 and transfer the blank material to the operating range of the transfer robot 21. While the pedestal 12 is moving toward the press machine, the air cylinder 15,1
5 to move the claws 17, 17 toward each other so that the distance between the blanks 6, 6 on the pedestal 12 matches the distance between the molds 22.

Since there are many types of press mold shapes depending on the product, some molds are not necessarily designed to be symmetrical, and products with different shapes may be processed at the same time, so in such cases, Air cylinder 1
5 and 15 may be adjusted to be different on the left and right sides.Also, although two guide holes 14 are provided in this embodiment, it is also possible to use only one guide hole and insert two claw pieces. Alternatively, the spacing may be adjusted by inserting only one claw piece into the guide hole and moving only one of the materials.

As explained above, the present invention is a material feeding device that can feed multiple blanks at the same time, and is a device that changes and adjusts the material to a desired interval immediately before feeding it to the press machine that uses the material, and is highly versatile. It is a supply device.
