Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to the process of manufacturing and processing thin plates such as veneer veneer, veneer plywood, fiberboard, paperboard, synthetic resin plate, metal plate, etc. This relates to a method and device for removing the accumulation of thin plates used in operations, and in particular, it involves continuously accumulating a large number of small [1] veneer veneers in a stacked state, and continuously removing this accumulation. This is a method and device for removing piles that are frequently used in the field of plywood manufacturing, where there are many work formats in which the plywood is broken down and supplied as individual small and medium veneer veneers to subsequent processes.

(B) Prior art Although there is no known prior art method and device for removing stacks of thin plates that have the same technical concept as the present invention, similar to the present invention, it is possible to In the first stage of the deposition process, a paper-like strip material is inserted between the layers of the thin plate to separate the layers and the layers are continuously deposited. Regarding the device etc. that facilitates
There is No. 2-79011 veneer polymerization method and device, etc., but these conventional devices are as follows: The top plate and the back plate are stacked separately and continuously, and the connected body of the top plate and the back plate is synchronously transferred in opposite directions, and the middle plates of the same size are completely synchronously transferred between both the front and back plates. A veneer polymerization method characterized by polymerizing and cutting the flexible connected body of the front and back plates during the transfer process to obtain a single-sized plywood.'' ``■, Invention of the method described in 1. above. In the device for direct use, a continuous feeding device for feeding out the connected body of the top plate, a continuous feeding device for feeding out the connecting body of the back plate provided opposite to the continuous feeding device, and a continuous feeding device for feeding out both of the connected bodies. A veneer polymerization device characterized by: a continuous conveyance device for feeding out the intermediate veneer, which is provided in conjunction with a conveyance device, and a veneer polymerization device for unwinding the intermediate veneer. When making a connection between a thin plate made of veneer and a mount-like strip material made of flexible connectors such as thread or tape, an adhesive is always required to attach the thin plate and the strip material, and the Since the flexible connectors, such as threads and tapes, are affixed integrally to the surface of the sheet, it is not possible to remove the strip of material from the surface of the sheet without leaving an intact trench.

(c) Problems to be Solved by the Invention As mentioned above, in the prior art, in order to facilitate the supply work by breaking up the deposit in the subsequent process, the interlayer of the thin plate is Insert a mount-like strip material made of flexible connectors such as threads and tape into the! In order to separate the layers and create a stack of individual thin sheets connected in advance, it was always necessary to attach a strip of material to the surface of the thin sheet using an adhesive. be. Therefore, since it is not possible to remove an intact strip of material from the surface of the sheet with this adhesive, such adhesive methods are not used in the normal sheet deposition and supply process. This was an attempt to eliminate the serious drawback that it could not be used for any other general products except for plywood products.

(b) Means for solving the problem The method of the present invention is to transfer the pile made by inserting a double-folded belt-shaped mount between the layers of thin plates in advance in the previous deposition process to the subsequent supply process. and the double-folded band-shaped mount inserted between the layers of the thin plates is pulled out from the tip and collected, thereby simultaneously drawing out the thin plates mounted on the mount. The device invention of the present invention comprises a) a pinch roller 1 for collecting a strip-shaped interleaving sheet folded double and inserted between layers of thin plates installed on the side of the place where the pile is taken down; and b) the pinch roller. This device is a device for removing stacks of thin plates, which has an elevating table associated with a level detector that detects and aligns the top surface of the stack in accordance with the feeding position of the roller.

(E) Function The method of the present invention will be explained in more detail with reference to FIGS. 1 and 2 of the attached drawings which illustrate the operational mode of the present invention. A belt-shaped cloth 1 synthetic resin film folded double between the layers of a thin plate 1a such as plywood, fiberboard, paperboard, synthetic resin board, metal plate, etc.

At the place where the interleaving paper pile 6 made of a bendable thin film-like material such as wire mesh is torn down, the double-folded mount a inserted between the layers of the thin plate 1a is also pinched by the pinch rollers 4a and 4b and pulled out from the tip. By collecting the thin plate 1b on the uppermost surface, which is mounted on the interleaving paper 2a, the thin plate 1b on the uppermost surface is simultaneously fed out to the subsequent process and continuously supplied to various manufacturing equipment, processing equipment, etc. be. Also, one pinch roller 4a.

Although not shown, the belt-shaped interleaving paper 2b, which is sandwiched between the two parts and collected at the same time, is a Lee-1v5 which is equipped with a torque motor, etc.
After winding it up into a reel-shaped interleaving paper 2C, or folding it into interleaving paper 2d one by one using a folding machine (not shown) that swings back and forth horizontally, the paper is returned to the previous stacking process. It will be recycled and reused.

Since the thin plate stack removal method of the present invention operates as described above, the work of feeding and supplying the thin plates 1a and 1b by removing the stack 6 for the subsequent process is performed by removing the stack 6.
Pinch rollers 4a and 4b pinch the tip of the strip-shaped interleaving paper 2a that is double-folded and inserted between the layers.
By holding the paper between the two sheets and pulling it out for collection, the work of collecting the interleaving paper 2a and the work of feeding and supplying the thin plates 1a and 1b proceed simultaneously, and this can be carried out efficiently by a single process operation. It is something that can be done.

(F) Embodiment The structure of the apparatus of the present invention will be described in more detail with reference to FIGS. A stack 5 made by inserting a double-folded strip of gold paper 2a' between the layers of the thin plate 1a.
is transferred to an appropriate transfer means, such as a forklift or a roller conveyor, and placed on the elevating tag /L/6 of the latter stage supply process, which is the place where the pile A is to be taken down.

Next, pull out the tip of the strip-shaped interleaving paper 2a that has been folded double and inserted between the layers, which has appeared on the top layer of the pile 6,
The elevating table 6 is installed above one side, and is sandwiched between pinch rollers 4a and 4b.
4a, 4bi are mounted on the double-folded interleaf paper 2a on the conveyor 7 connected to the pinch rollers 4a, 4b by rotating continuously or intermittently in accordance with the supply work of the subsequent stage process. The thin plate 1b that is fed out in this state is delivered and continues to be transported to the subsequent process. 1
On the other hand, the strip-shaped interleaving paper 2b, which is pinched by the other pinch rollers 4a and 4b and collected at the same time, is wound up on an IJ-/l/5 equipped with a torque motor (not shown) and turned into a reel-shaped backing paper. It is either folded into 2C, or it is folded into 2D slip sheets by a folding machine that swings back and forth horizontally (not shown), and then returned to the -iJ stage stacking process and reused. It is something. Furthermore, this one piece of paper 2a
, 2b and feeding out the thin plates 1a and lb, the pile 4
As the stacking level decreases due to the removal of R3, the unloading path gradually becomes sloped, making it impossible to safely feed out the thin plates 1a+1b.
The level detector 8 such as a gold photoelectric switch or a limit switch detects the stacking level f on the uppermost surface of the stack 6 in accordance with the feeding position of the thin plate 11) on the top surface of the stack 6 and the slip sheet 2 a, - In order to always align with the feeding positions of 4a and 4b, the level detector 8 is connected to the lifting mechanism 9 such as a hydraulic device installed in the lifting chime lv6 to automatically control the accumulation level. It is configured as follows.

Since the apparatus for removing the stack of thin plates according to the present invention is constructed as described above, the operation of feeding and supplying the thin plates 1a and 1b by removing the stack 5 for the subsequent process is performed only on the top layer of the stack 6. Pinch roller 4a at the tip of the strip-shaped interleaving paper 2a that is double-folded and inserted between the layers.
, 4b and pull it out for collection as well, thereby recovering the interleaving sheets 2a, 2b and the thin plates 1a, 1.
Not only is it possible to carry out the unwinding work in step b simultaneously, and this can be carried out efficiently through one process operation, but also because of the reduction in the level of the deposit due to the removal of the deposit 5. Thin plate 1a.

Even in situations where the feeding work of 1b becomes unstable, always
The deposition level of the deposition 6) v such that the horizontal conveyance of the deposit 6 can be maintained
By connecting a level detector 8 for detecting the level to the lifting tape/I/6, the unwinding operation is stabilized.

(G) Effects of the Invention Since the present invention has the above-mentioned configuration and operation, it is possible to facilitate the supply work by removing the accumulated material in the subsequent process, which was a drawback of the conventional apparatus. In the previous deposition process, a mount-like strip material made of a flexible connecting body such as thread or tape is inserted between the layers of thin sheets to separate the layers and connect the individual thin sheets into a series. When attempting to make 5a in advance, it was necessary to attach the strip material to the surface of the thin plate using an adhesive.
Since the attached strip material cannot be removed intact from the surface of the sheet, such bonding method is not used at all for other general products except for some plywood products in the normal sheet stacking and feeding process. The present invention has been able to eliminate all important points such as not being able to do this, and the present invention completely eliminates the use of auxiliary materials such as adhesives in the previous deposition process. Cloth 1 Interleaf paper 2a, 2 made of flexible belt-shaped thin film-like material such as synthetic resin film or wire mesh
The pile 6 made by double-folding b, 2c, and 2d and inserting them between the layers of the thin plate 1a is recovered by pulling out the double-folded interleaving paper 2a inserted between the layers of the thin plate 1a from the tip in the later supply process. By doing this, the thin plates 1a, Ll)' mounted on the interleaving paper 2a could be fed out at the same time, so the work of collecting the interleaving papers 2a and 2b and the thin plates 1a and 1b. The unwinding operation is efficiently completed in four simultaneous motions, and the gap between the layers of the thin plates 1a and 1b is completely covered with the interleaving paper 2a.

By separating the sheets into sections 2b, we were able to eliminate the malfunction of unwinding multiple sheets at once and provide a reliable function for unwinding each sheet. This is an invention that has tremendous implementation effects that contribute to optimization, stabilization, and efficiency.
