Description

[Detailed description of the invention] [Technical field] The present invention relates to a net take-out device that can automatically take out only the nets from a load in which nets and board materials such as veneers are alternately stacked. .

[Background technology] When dyeing board materials such as veneers, it is necessary to dye the many boards stacked one above the other evenly.
A net is interposed between each plate as a spacer,
A slight gap is formed between the plates so that the dyeing liquid permeates each plate uniformly. When removing the board after dyeing,
A board material suction head with a suction section at the bottom is placed above the board material, the suction section is applied to the surface of the board material, the suction force of the suction section is used to attract the top surface of the board material, and the device is moved in this state automatically. The plan is to take out the board material at the same time. However, because the net cannot be suctioned by the suction part of the device,
It was impossible to remove it using this device.

[Purpose of the invention] The present invention has been made in view of the above points, and provides a net take-out device that can take out and transport only the nets from a load in which nets and boards are alternately loaded. The purpose is to provide

[Disclosure of the Invention] That is, the net take-out device of the present invention includes a transfer device 4 which is disposed above the load 3 on which the net 2 is loaded on the top surface of the plate material 1 and is movable vertically and laterally. , two V-shaped arms 5 attached to the lower part of the transfer device 4 and driven to freely widen or narrow the interval between their lower ends; A deformable spring portion 10 is formed, an insertion needle 11 is formed at the tip, and the insertion needle 11 at the tip is provided with an insertion spring 6 that can be freely inserted into the mesh 7 of the net 2. 6 to grab and pull up the net 2, the removal of the net 2 can be automated, and by using the insertion spring 6 whose spring portion 10 is elastically deformed, the plate material 1 will not be damaged, and the insertion The above object is achieved by preventing the spring 6 from becoming deformed.

The present invention will be described in detail below based on examples. The net 2 is made of polyethylene or the like, and the size of the mesh 7 can be about 2 to 10 mm. As shown in FIG. 1, a transfer device 4 is disposed above a loaded object 3 in which nets 2 and plate materials 1 such as dyed materials are alternately stacked so as to be able to be driven vertically and laterally. . This transfer device 4
Two arms 5, 5 consisting of an upper arm 8 and a laterally long plate-shaped lower arm 9 are attached to the lower part of the , and each lower arm 8,
A fixing pin 17 is fixed to the inner surface of the spring 8, and a spring 6 is attached to the fixing pin 17 so as to face diagonally inward. The two arms 5, 5 are vertically moved so that the distance between the lower ends can be widened or narrowed. The insertion spring 6 is made of steel or the like, and as shown in FIG. 2, a spring portion 10 made of a helical spring that can be elastically bent and deformed is formed at its base, and an insertion needle 11 is formed at its tip. is formed. The wire diameter a of the insertion spring 6 is 0.6 to 1.2 mm, the wire length l ₁ of the spring part 10 is 20 to 50 mm,
The outer diameter b of the spring part 10 is 5 to 10 mm, and the insertion part 11
A wire length l ₂ of approximately 20 to 70 mm can be used. Further, the number of wires of the insertion spring 6 fixed to the lower arm 9 can be adjusted depending on the weight of the net 2, etc., and is not limited, but since even one insertion spring 6 has sufficient strength, one
It is also possible to use one per location. In addition, the tip of the insertion needle 11 is processed into a spherical surface 18 so that it can easily slide.
has been applied.

Therefore, in order to separate the plate material 1 and the net 2 from the load 3 loaded with the net 2 and the plate material 1, an apparatus as shown in FIG. 3 can be used. In the figure, 12 is a dyeing basket in which the load 3 after dyeing is placed, 13 is a transport conveyor on which the board 1 is conveyed toward the dryer, and 14 is a container in which the nets 2 are taken out from the dyeing basket 12 and stacked. 4 is a table lifter, and 4 is a transfer device. A fitting part 15 that slidably fits into a rail (not shown) is formed in the upper part of the transfer apparatus 4, and a plate suction head 16 and a plurality of arms 5 are provided in the lower part of the transfer apparatus 4. In the state shown in FIG. 3, the plate material 1 such as a dyed veneer is adsorbed on the lower surface of the plate material suction head 16, and the material 1, such as a veneer, is sucked from the dyeing basket 12 to the conveyor 13.
The figure shows a state in which the net 2 in the dyeing tank 12 is grabbed by each arm 5 while being transferred upward. Board material 1
After placing the material on the conveyor 13, the transfer device 4 is moved slightly upward and moved toward the table lifter 14, thereby sucking the plate material 1 in the dyeing basket 12 again on the lower surface of the plate material suction head 16 and at the same time removing it from the arm 5. The net 2 is loaded onto the table lifter.

Now, to explain in more detail the case where only the net 2 is taken out from the loaded object 3, the transfer device 4 is moved to a position above the loaded object 3, as shown in FIG. In the open state, move the device 4 downward, insert the insertion needle 11 at the tip of the spring 6 into the mesh 7 of the net 2 as shown in Fig. 4, and press it against the surface of the plate 1, and at the same time as shown in Fig. 1b. Both arms 5, 5 are rotated inward. Here, since the tip of each insertion spring 6 is spherically processed 18, the insertion spring 6 slides on the surface of the plate 1 without damaging the surface of the plate 1. Further, the angle θ between the plate material 1 and the insertion spring 6 is preferably about 25 to 50 degrees. Next, when both arms 5, 5 are rotated further in opposing directions so that the distance between their lower ends is narrowed, the net 2 is moved between the two insertion springs 6, 6 as shown in FIGS. 1c to 1d. As a result, the net 2 is gripped by the insertion spring 6. With the net 2 gripped by the insertion spring 6 in this manner, the transfer device 4 is driven upward and moved toward the table lifter 14, and both arms 5, 5 are spread as shown in FIG. is dropped and loaded onto the table lifter 14.

By moving the transfer device 4 in this manner, the plate material 1 and the net 2 can be automatically separated from the dyeing basket 12. Further, in the present application, the insertion spring 6 is made of steel, and the spring part 10 made of a helical spring is formed at the base, and the insertion needle 11 is formed at the tip, so that the insertion spring 6 is made of steel. Even if the insertion needle 11 of the insertion spring 6 does not fit into the stitch 7 of No. 2, the insertion needle 11 will not bend due to the deflection of the spring portion 10 and will not return to its original shape. It has the advantage that it has a longer lifespan than a straight insert spring made of resin, and can be used semi-permanently. Moreover, since the insertion part 11 is made of spring steel, its strength is increased, and the number of springs per place can be reduced to one instead of the eight that would be required if the insertion spring were made of a resin material such as polypropylene. Then, Net2
There is also the advantage that the insertion spring 6 can be easily inserted into the stitches 7.

[Effects of the invention] As described above, the present invention includes a transfer device, two V-shaped arms that are provided at the bottom of the transfer device and are driven so that the distance between the lower ends can be widened and narrowed, and the lower part of each arm. It is attached to the net so that it is inclined inward, and the insertion needle at the tip is equipped with an insertion spring that can be freely inserted into the mesh of the net.The lower end of the insertion spring is inserted into the underside of the net, and then the net is inserted and the spring top is inserted. By sliding the net, the net can be inserted between the springs, and the net can be automatically removed from the load with a simple structure.In other words, by inserting the insertion needle into the mesh, the net can be pulled out. It is a device that can be used to lift a net by hanging it, and it can be lifted using the mesh of the net without having to bend and hold the part of the net that will be lifted. There is an advantage that the net used as a suspended object can be lifted and moved without damaging or deforming it. In addition, since the base of the insertion spring is formed of an elastically deformable spring part, even if the tip of the insertion spring does not fit properly into the mesh of the net, there is no possibility that the spring part will be deformed and not restored. It has the advantage of long life and usability.
