Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for a disk feeder that supplies blanks to a transfer press.

The simplest conventional method used a vacuum cup to suck up the top one of the stacked blanks, which was then received by a finger attached to a feed bar and conveyed one by one. However, with this method, the feed bar must be long enough to reach the stack feeder.

2 From the day stack feeder to the first process 3~
Several sets of fingers are required to convey the material six times in sequence.

3. The longer the feed bar is, the more difficult the work will be when replacing the mold.

There were other drawbacks.

In contrast, conveying devices using magnetic rollers, vacuum cups, and magnets have been used, but the magnetic roller method has drawbacks such as limitations on the size of the blank material due to the size and pitch of the rollers, and problems such as meandering of irregularly shaped blank materials. In the vacuum cup method, there is interference with the two-plate detection device, and the position of the cup changes depending on the shape, and in the shuttle method using a magnet, there is interference with the vertical movement of the vacuum cup, which has drawbacks in high-speed followability.

The present invention aims to provide a conveying device for a chain type disk feeder which eliminates this drawback.

To explain the present invention with reference to the drawings of one embodiment, when blank materials 2 loaded on a pallet 1 are carried on a trolley 3 and settled in a fixed position,
The blank material 2 is lifted by a certain amount by a lift cylinder 4, and the blank material 2 is taken up one by one from the top by a vacuum cup 6 which is moved up and down by an air cylinder 5. In addition, as auxiliary devices, there is a magnetic floater 7 that separates the blank material, and a blank holding claw 8 that can supply the blank material even when switching the trolley 3, and the blank material 2 picked up by the vacuum cup 6 is hung on the sprocket 9. The chain 10 is driven by the slide or crankshaft of the press, and is rotated intermittently using a one-way clutch (not shown). Therefore, when the chain 10 is stopped, the blank material delivered to the vacuum cup 6 is intermittently attracted to the magnet 11 and conveyed, and
It comes to the position of the air cylinder 12 provided above the A position of 0. A two-sheet detection and two-sheet blank ejection device is provided in the middle (not shown). A frame 13 is provided below near position A of the chain 10 along the chain 10, and the chain 15 is hung on sprockets 14 rotatably attached to both ends of the frame 13.
There is a roller 1 guided by the frame 13.
There is a magnet 19 on a plate 18 connected to the block 17 supported by the magnet 6 and attached to the top of the block 17.

Additionally, a roller 2 guided separately by the frame 13
0, and the block 21 supported by this is also connected to the chain 15 and block 17 at the opposite position. A guide bar 22 protrudes from the block 21, into which a slider 23 is inserted, and a pin 24 rising from the slider 23 is inserted into a hole made in the feed bar 25. Therefore, when the feed bar moves to the left, block 21 moves to the left, and block 1
7 moves to the right. The blank material thrown into the air cylinder 12 is attracted to the magnet 19 and is in a position.

When the feed bar 25 moves to the left, the blank material is in the empty position. At this time, the fingers 26 are in the empty position and are clamped here to grasp the blank before conveying it. At this time, the magnet 19 returns to the empty position to receive the next blank material, and this process is repeated to convey the blank material.

This position is the first step. 27 is a clamp unit, and 28 is a column.

According to the present invention having the configuration and operation described above,
It has the following advantages over the conventional one.

1. The feed bar is short and good.

2 One set of blank fingers is sufficient.

3. Since it is transported using a magnet attached to the chain, there is no operational interference with the vacuum cup, and it is possible to transport fairly small blank materials (up to about 100 holes).

4 There is no meandering as the product is transported while hanging.

5 At the last point, the support direction is changed from the upper side to the lower side, so 2-dimensional (clamp, advance, unclamp, return) and 3-dimensional (clamp,
lift, advance, down, unclamp,
You can use either of the feed bars that perform the movement (return).

6. All conveyance is mechanically linked to the press, so high speed is achieved.

7 To eject two blanks, just push them down.
