Description

[Detailed description of the invention] The present invention relates to a plate member separating device.

This seed plate separation device is used for separating and feeding blanks of press machines, particularly for separating and feeding thin plate members.

A conventional plate member separation device stacks a plurality of plate members in a storage frame, a transfer plate is provided above the plate members so as to be movable up and down, and a suction pad is provided on the transfer plate. , the transfer plate is lowered, the suction pad adsorbs the plate member, it rises while adsorbing, separates the plate members one by one from the top layer, and feeds the separated plate members to a press machine etc. It has been known.

However, in the case of this conventional structure, during the separation operation after adsorption, the plate member located directly below is also lifted up along with the plate member to be separated.
That is, it is difficult to separate due to the adhesion effect due to the influence of an oil film such as a rust preventive agent, and this phenomenon becomes more pronounced as the plate becomes thinner, which is disadvantageous in that it is impossible to reliably separate one sheet at a time.

The present invention aims to provide a plate member separating device that can eliminate these disadvantages.

Hereinafter, the gist of the present invention will be explained with reference to the accompanying drawings.

In this device, a plurality of plate members 2 are stacked on a storage frame 1, a transfer plate 3 is arranged above the plate members 2 so as to be movable up and down, and a suction pad 4 is arranged on the transfer plate 3. In the device in which the plate members 2 are separated one by one by the vertical movement of the transfer plate 3 and the suction action of the suction pad 4, the transfer plate 3 is freely stopped at a position A in the middle of its ascent by the cylinder mechanism 5. A mooring member 6 is disposed on the upper side of the plate member for mooring at least the plate member 2b located directly below the plate member 2a, excluding the plate member 2a to be separated, at the mid-ascent position A of the transfer plate 3. This is a plate member separating device characterized by the following.

Further, this example will be explained.

In this embodiment, the plate member 2 is a disk-shaped blank, and the storage frame 1 is made up of three positioning rods 7, which are erected on a base 8 at three equal intervals.

A mounting plate 9 is disposed at the center of the base 8 so as to be movable up and down by a replenishing cylinder 10, and a plurality of plate members 2 are stacked on this mounting plate 9. Further, in this embodiment, the feeding body 11 is arranged to be movable between the position above the plate member 2 and the take-out conveyor 13 by the action of the horizontal guide shaft 12 by the rod of the feeding cylinder 11a. A vertical guide shaft 14 is provided vertically on the feeding body 11, the transfer plate 3 is attached to the vertical guide shaft 14, and two vacuum suction pads 4 are attached to the transfer plate 3.

Further, the cylinder mechanism 5 of this embodiment has a first
Consisting of a cylinder 15 and a second cylinder 16, the first cylinder 15 is attached to the feeding body 11, the second cylinder 16 is connected to the cylinder rod 15a of the first cylinder 15, and the cylinder rod 16a of the second cylinder 16 is connected to the cylinder rod 16a of the second cylinder 16. The transfer plates 3 are connected to each other so that the transfer plates 3 can be freely stopped at position A during the ascent.

Further, in this embodiment, a frame 17 is arranged in parallel at the upper side position of the storage frame 1, a cross plate 18 is installed on this frame 17, and a slide plate 20 is attached to the cross plate 18 by a cylinder 19 for projecting and retracting. , a pin 21 is formed on the slide plate 20 , and the mooring member 6 is formed with an L-shaped side surface and a sharp tip, and the mooring member 6 is directed toward the plate member 2 . The mooring member 6 is provided with a cam diagonal groove 2.
2 is planted, this cam diagonal groove 22 is engaged with the pin 21, and the slide plate 20 is slid by the protrusion/retraction cylinder 19, and the engagement between the pin 21 and the cam diagonal groove 22 causes The mooring member 6 is made to move in a protruding and retracting manner.

Moreover, the rubber film body 23 of the suction pad 4 of this embodiment
A bowl-shaped hard regulating body 24 is attached to the inner surface, and suction grooves 25 are formed in this regulating body 24.

Since the present embodiment has the above configuration, as shown in FIG. 1, the feeding body 11 is positioned above the stacked plate members 2, and first, the first cylinder 15 and the second cylinder 16 are operated, The transfer plate 3 is lowered.

As a result, the suction pad 4 becomes as shown in FIG.
It comes into contact with the uppermost plate member 2a and attracts the plate member 2a.

At this time, when the first and second cylinders 15 and 16 protrude, the suction pad 4 is originally at the lowering limit position B.
However, since the suction pad 4 contacts the plate member 2 first, the working fluid (air pressure, hydraulic pressure, etc.) in the second cylinder 16 escapes, and the suction pad 4 stops at the contact position. Further, during suction, since the upper surface of the plate member 2 comes into contact with the regulating body 24, the relative position between the suction pad 4 and the plate member 2 remains constant.

This suction pad 4 suctions the uppermost layer, that is, the plate member 2a to be separated, and when this is confirmed, only the second cylinder 16 moves upward and stops midway at position A in the middle of the upward movement, as shown in FIG.

Then, the protruding and retracting cylinder 19 operates, and the mooring member 6 protrudes to engage the side surface of the plate member 2b. Incidentally, the tip of the mooring member 6 may be slightly inserted between the plate member 2a and the plate member 2b.

After that, the first cylinder 15 is operated to rise,
As shown in FIG. 1, the suction pad 4 stops at the upper limit position C, and the mooring member 6 is retracted.

At this time, since the plate member 3b located directly below the plate member 2a to be separated is moored by the mooring member 6, only the plate member 2a to be separated rises, and the plate member 2b located directly below it is moored. It does not get dragged up and rises, and it is possible to separate each sheet more reliably. The separated plate member 2a is then transferred to a take-out conveyor 13 or the like by the feeding body 11.

As described above, in the present invention, the transfer plate 3 is disposed by the cylinder mechanism 5 so as to be able to stop at the mid-ascent position A, and is placed above the plate member 2 at least immediately below the plate member 2a, excluding the plate member 2a to be separated. Since the mooring member 6 for mooring the plate member 2b at the moving plate 3 at the mid-ascent position A is provided, the mooring member 6 is moored except for the plate member 2a to be separated, and the mooring member 6 is pulled up. can be prevented from occurring, and each sheet can be reliably separated.

In particular, since the mooring action takes place at position A on the way up, even if the adsorption position of the plate member 2 changes, the position A on the way up remains constant, and mooring can be performed more accurately at that position, making it possible to separate more reliably. , therefore, an improvement in efficiency can be expected.

As described above, the intended purpose can be fully achieved.
