Description

[Detailed Description of the Invention] The present invention relates to a material adsorption device in a material supply device.

A material feeding device is a device that feeds plates one by one to a press or other conveying device.

The board materials loaded on the pallet are sucked one by one by a suction tool and supplied to the above-mentioned apparatus.

Boards must be supplied one at a time, and two boards must be supplied one at a time.
In order to prevent more than one sheet from being adsorbed, an uneven portion 2a may be formed on the plate material using a mold.

Since these uneven portions are formed at the same position on the board, the board will be slightly inclined when loaded.

(Fig. 2) In addition, plates tend to have cracks, which may cause the plates to tilt when loaded.

On the other hand, as devices for adsorbing plate materials, there are vacuum suction cups and suction tools using electromagnets.

In the case of a plate material with holes, a vacuum cup cannot be used because air leaks, so a suction tool using an electromagnet is used.

Conventionally, as shown in FIG. 1, the plates 2 loaded on a pallet 3 were sucked and fed one by one by a suction tool 1 fixed to a lifting member 5 operated by an air cylinder 5'.

In this case, there is no problem if the board is held horizontally, but if the board is tilted as shown in Figure 2,
Since the suction force of the suction tool does not work properly on the plate material, the feeding operation cannot be carried out satisfactorily.

For this reason, there have conventionally been suction devices attached via rubber hoses, but there have been some problems with the ability to restore the material after suction.

The present invention has been made to solve this problem and improve the conventional adsorption device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be explained in detail based on the drawings.

In FIG. 3, a suction tool 1 using a magnet is fixed to an elevating member 5 via a bellows 4.

The bellows 4 is made of an elastic material (such as rubber).

Compressed air is introduced into the bellows 4 in order to provide sufficient flexibility when the suction tool 1 adsorbs the plate material 2, and to provide sufficient rigidity to restore the shape of the bellows after adsorbing the plate material 2. May be supplied.

(FIG. 5) In FIG. 5, compressed air whose pressure is regulated by a pressure regulator 8 is supplied to the bellows 4 via a solenoid valve 6.

The supply timing is immediately after the suction tool 1 descends and suctions the plate material 2.

This timing, that is, the control of the electromagnetic valve 6 is performed by detecting the position of the suction tool 1 with the detector 7 and using the detected signal.

In FIG. 4, the suction tool 1 is freely tilted by the action of the bellows 4, so that it can suction the tilted plate material 2, and as shown in FIGS. can be delivered to the magnet 10 in the correct posture.

Since the present invention has the above-described configuration, it is possible to feed plate materials stacked at an angle to a press or other conveying device.
