Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a plate separation and take-out device that separates and takes out each plate from stacked plates.

[Technical background of the invention and problems with conventional technology]

First, the technical background of the present invention will be explained based on FIGS. 1 and 2.

The illustrated device is a front view and a side view of a conventional sheet material separation and extraction device 1, which is constructed by assembling a rectangular frame 3 by appropriately combining shaped steel, etc., and has four corners installed at the bottom and at the middle height. A slat conveyor 7 is provided which circulates between the sprockets 5.

Slats (pieces) 9 of this slat conveyor 7
are provided only in the longitudinal dimension of the frame 3, and are not provided in other parts. The slat conveyor 7 is movable in both forward and reverse directions using an electric motor 11 as a driving source. FIG. 1 shows the slat 9 located at an intermediate height of the frame 3.

A pallet 15 on a roller conveyor 13 or the like is fed into the circulation path of the slat conveyor 7 from the left side in FIG. It is positioned by moving left and right at the lower stage of the frame 3.

On the pallet 15, standard size plates W, such as 4' x 8', 3' x 6', 300 x 1100, etc., are stacked on a wooden stand 21 in close contact with a ruler 23.

Further, above the chain conveyor 19, there is provided a lift frame 29, which is moved up and down by a circulation chain 27 driven by an electric motor 25, and is equipped with an appropriate number of suction members 31. When the slats 9 of the slat conveyor 7 do not cover the upper part of the plate material W, this suction member 31 comes into contact with the descending member and adsorbs the topmost sheet of the plate material W to the height shown in FIG. Lift it up in a horizontal position.

Next, the above-mentioned slat 9 is positioned below the suction member 31, the plate material W is lowered onto it, the suction member 31 is retracted upward, and the plate material W is placed in the first position.
They are taken out by a slat conveyor 13 in the direction of the front and back of the paper in the figure.

In the conventional plate material separation device 1 as described above, one reference surface of the plate material W (the left end side surface of the plate material W in FIG. 1)
A magnetic separator 33 was provided nearby, and each time a pallet 15 was carried in or taken out, the magnetic separator 33 had to be flipped up and evacuated as shown in FIG.

Further, the stopper 35 (see FIG. 2), which sets a reference plane provided at almost the same position as the magnetic separator 33, also needs to be retracted to a position where it does not interfere with the plate material W.

As mentioned above, the conventional plate material separation/takeout device 1 requires a long magnetic separator 33 that spans the entire height of the accumulated plate materials W, and also requires the stopper 35 to be retracted, resulting in a complex structure and high cost. There was an inconvenience.

[Purpose of the invention and its outline]

The present invention has been made to solve the above-mentioned disadvantages of the conventional plate material separation and extraction apparatus, and is provided with a swingable magnetic separator on a lifter frame to which an adsorption member is attached.

[Example of idea]

Examples of the present invention are shown in FIGS. 3, 4, and 5.

An adsorption member 31 is provided on the lift frame 29 via a bracket 37, and a magnetic separator mounting body 41 is provided via a wire 39 suspended from the same bracket 37 to a portion extending directly above the edge of the plate material W. .

The wire 39 is bent in a substantially horizontal direction by a pair of pulleys 45 provided on a pulley stand 43 provided above the bracket 37, and the wire 39 is bent in a substantially horizontal direction by a pair of pulleys 45 provided on a pulley stand 43 provided above the bracket 37. It passes through a connecting plate 51 at the tip and is connected to a bullet 53 provided at the tip of the fluid pressure cylinder 47.

The magnetic separator mounting body 41 is made of sheet metal or the like and has a yoke shape, and guide rods 55, 55 extending upward are provided near both ends of the magnetic separator mounting body 41.
Two pairs of guide blocks 57, 57 provided on the top surface of
It roams between.

Two shaft rods 5 are attached to the magnetic separator mounting body 41.
A magnetic separator 33 is attached by 9 and 59, and the magnetic separator 33 is rotatable around the upper shaft 59, and the magnetic separator 33 is rotatable around the lower shaft 59 toward the magnetic separator 33. This is supported by a long arc-shaped hole.

In addition, contact plates 61 and 6 made of non-magnetic material are provided at both left and right ends of the surface corresponding to the edges of the plate material W of the magnetic separator 33.
1 is attached by appropriate means.

In the above configuration, the lift frame 2
9 is lowered to adsorb the uppermost stacked plate material W by the adsorption member 31, when the piston rod 49 of the fluid pressure cylinder 47 is made to protrude, the magnetic separator attachment body 41 etc. are moved against the bombardment 53. It descends due to its own weight and is located at the end of the stacked plates W. At this time, since the contact plate 61 whose lower part is bent in the direction away from the plate material W acts as a guide, the swinging of the magnetic separator 33 also prevents the ends of the stacked plate materials W from being uneven. However, the magnetic separator 33 can be located at the end of the plate W.

After the suction member 31 suctions the uppermost plate W, the piston rod 4 of the fluid pressure cylinder 47
9 and lift the magnetic separator mounting body 41 via the wire 39, the magnetic separator 33 separates from the other plates than the plate W attracted by the adsorption member 31, so the other plates fall. Therefore, only the uppermost plate can be reliably separated and taken out. Note that when the piston rod 49 of the fluid pressure cylinder 49 is moved in and out, the wire 39 is not loosened due to the action of the bullet 53.

[Effect of idea]

As is clear from the above embodiment, the present invention provides a vertically movable magnetic separator mounting body 41 on a vertically movable lift frame 29 equipped with a suction member 31 that attracts a plate material W, and the magnetic separator mounting body 41 is vertically movable. body 41
, the plate material W is sucked by the suction member 31.
A magnetic separator 33 for separating the plate material W is provided close to the end of the plate material W so as to be able to freely swing up and down, and a magnetic separator 33 for separating the plate material W from its lower end is provided on the side surface of the side where the magnetic separator 33 contacts the plate material W. It is provided with a contact plate 61 bent in the direction.

With the above configuration, according to the present invention, when the lift frame 29 is lowered and the uppermost stacked plate material W is sucked and lifted by the suction member 31,
Positioning the magnetic separator 33 at the end of the plate material W,
The plate material W can be separated one by one, and by lifting the magnetic separator 33 at this time, the plate materials other than the plate material W adsorbed by the adsorption member 31 are separated from the magnetic separator 33. It is possible to reliably separate each sheet. Furthermore, when the magnetic separator 33 is positioned toward the end of the stacked plates as described above, even if the edges of the stacked plates are uneven, the lower part of the contact plate 61 will move away from the plates. Since it is bent and the magnetic separator 33 is swingably provided, the magnetic separator 33 can be easily positioned on the end side of the plate material W.

It is also clear that the design can be changed without departing from the technical idea of the present invention.
