Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floater-based moving device used in a press material supply device.

Conventionally, in a press material supply device, a movable pallet 9 loaded with plate materials 10 is stopped at a plate material supply station 3, as shown in, for example, Japanese Utility Model Application Publication No. 56-147940 filed by the same applicant. the lift cylinder 6 installed below that position.
The plate material 10 is pushed up to a certain height, passed between the blank holder and the magnetic floater 20 of the floater base, which is movably provided on the body of the machine at that height, and then the vacuum cup 11, which is provided above the magnetic floater 20 and the blank holder, is moved upward and downward. The sheets were taken out one by one and fed to the press. This floater base was run by hand on a rail set at a high position,
When pressing work is finished leaving a blank material on the floater base and starting processing the next blank material,
The floater base is difficult to move because the remaining materials are heavy, and the high rails make it difficult for workers to access. It also had drawbacks, such as the work being dangerous.

The purpose of the present invention is to eliminate these drawbacks and provide a floater-based moving device that can be driven by a motor and improve running performance, as well as improve workability and work danger by lowering the rail position. .

Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1, 2 and 3, press 1
It shows the material supply device installed on the side. A pair of pallets 2 are placed on a fixed long pallet truck 3 at an interval such that when one is at material supply position A, the other is at blank loading position B, and can be freely fed on rails 4 installed at the height of the floor surface. It is provided in A blank guide 6 can be fixed to the pallet 2 in accordance with the shape of the blank material 5 to be loaded. A lift cylinder 7 is provided below the material supply position A. The pallet 2 and the pallet truck 3 are provided with holes 8 through which a lift cylinder 7 pushes up the blank material 5. The pallet truck 3 is driven by motor devices (including wires) 9, 9 and travels on the rails 4, and the pair of pallets 2 is moved between positions A and B. The floater base 10 is a gate-shaped truck that straddles the pallets 2 fixed to the pallet truck 3, and is provided so as to be able to run freely on a rail 11 that is installed on the outside of the rail 4 and parallel to it at the height of the floor surface. There is. The rail 11 is longer than the rail 4, and the pallet truck 3 at the blank loading position B
dodge the floater base 10 and move to the preparation position C, C.
It is now possible to drive up to. A floater plate 12 is replaceably attached to the upper surface of the floater base 10. Generally, the floater plate 12 is converted and used for each blank material 5 to be handled, and includes a hole 13 that matches the blank material 5, a magnetic floater 14 and a blank holder 15 that are attached to the periphery of the blank material 5 with a slight gap. and is provided. Stopper 16 for floater base 10
However, a clamper 17 is provided at a position corresponding to the material supply position A, and the floater base 10 can be stopped at position A correctly. The floater base 10 is also provided with a limit switch 18 for issuing a stop signal at the end of the rail 11.
Floater base 10 stopped at material supply position A
At the top of the press 1, there is a bracket 1 extending from the press 1.
A suction tool 21 is provided which can be raised and lowered by a cylinder 20 to which a cylinder 9 is fixed. A device (not shown) for conveying the blank material 5 taken out by the suction device 21 to the press 1 is provided. Stopper 2 that correctly stops the pallet truck 3 at the material supply position A
2 and a clamper 23 are provided. An operation panel 24 for operating the pallet truck 3, floater base 10, etc. of the material supply device is provided in front of the press 1.

In Figures 4 and 5, floater base 1
0 travel drive system is shown. A rotation transmission shaft 25 is rotatably supported at the top of the portal frame of the floater base 10. Further, a traveling motor 26 is fixed to the frame. A chain 29 is attached to a sprocket 27 fixed to the output shaft of the traveling motor 26 and a sprocket 28 fixed to the rotation transmission shaft 25. Between the sprockets 30, 30 fixed to the rotation transmission shaft 25 and the sprockets 31, 31 fixed respectively to the pair of wheels 33, 33 of the floater base 10, chains 32, 32 passing through the inside of the portal column are hung. There is. The blank holder 15 attached to the floater plate 12 is provided with a hook 15a for temporarily holding the blank material 5 to enable continuous operation of the press 1 when the pallet 2 is replaced.

Next, we will discuss the effect. 1 to 5, when moving on to processing the next type of blank material 5', the floater base 10 in the preparation position C is attached to the floater plate 12 corresponding to the blank material 5' to separate two blank materials. A magnetic floater 14 and a blank holder 15 are prepared. Also, the pallet 2 at the blank loading position B is loaded with the next blank material 5'.
A blank material 5' is loaded. When the lift cylinder 7 descends, the clamper 17 is removed by a signal from the operation panel 24, leaving some residual material in the blank holder 15 of the floater base 10 at the material supply position A, and the two floater bases 10, 1 are removed.
0 running motor 26 is started, and sprocket 2
Rotation transmission shaft 25 via 7, 28 and chain 29
, sprocket 30, 31 and chain 3
2 drives the wheels 33 through the floater base 1
0 from position A to C, from position C to A,
The limit switch 18 operates and the driving motor 2
6 stops and stops at a fixed position. Tighten the clamper 17. The pallet truck 3 is moved by operating the motor device 9 or the like. The blank material 5' is pushed up to a certain height by the lift cylinder 7, separated into two by the magnetic floater 14, and taken out one by one from the top by the suction tool 21 and supplied to the press 1. When the blank material 5 becomes less, some amount is transferred to the hook 1 of the blank hoarder 15.
Lower the lift cylinder 7 while leaving it at 5a,
The pallet truck 3 is running and the pallet 2 is fully loaded.
Replace with The floater base 10 sent to position C further prepares for the next step and waits.

As is clear from the above explanation, according to the present invention, the floater base is driven by a motor, so it has good running performance, the rail is located low, so it is easy to access, and the work is easy. Since it is built into the blank, it is less dangerous, the next preparation can be made in advance, and the time required to replace the blank with a new one is shortened, which has great practical effects and advantages.
