Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves feeding plate-like objects, particularly veneer veneers of a certain width from which defective parts have been removed, to a conveyor at irregular intervals. By linking the following plate-like objects with the conveyor, the following plate-like object is quickly brought close to the preceding plate-like object, and while being held between the drive body and the plate-like object receiver, the drive body rotates at a low speed. This invention relates to a device for assembling plate-like objects that uses rotational force to reliably bring end faces together and assemble them into a group of continuously arranged plate-like objects.

Conventionally, this type of work has mainly involved a method of manually assembling and inserting individual plate-like objects, which have been piled up irregularly overlapping each other, into a group of continuously arranged plate-like objects each time they are fed to a post-processing machine. had been adopted.

However, manual work is not only inefficient and has a limited processing capacity, but also tends to cause adjacent plate-like objects to overlap during insertion, causing the gap to widen, resulting in insufficient drying of the overlapped parts in the post-processing machine, and a decrease in the filling rate. It was the cause of things like this.

In addition, conventional non-manual equipment uses a clutch brake to transport and stop the preceding plate-like objects, and then brings the following plate-like objects together one after another to form a group of continuously arranged plate-like objects. had been adopted.

However, starting with a clutch brake,
Variations occur when stopped, and as the conveyance speed increases, variations tend to increase.
In addition, the impact force at the time of colliding increases, so when used directly to match the processing capacity of the front and rear processing machines, the assembled plate-like materials may have widening of the interval, overlapping, or bending of the front and rear edges. There was a significant decrease in yield, filling rate in post-process machines, and work efficiency.

In addition, it reduces variations when starting and stopping, and reduces the impact force when colliding, resulting in wider spacing, overlapping, and
Limiting the conveyance speed to a low speed to prevent bending, etc. reduces the throughput, and direct connection will reduce the throughput of the upstream and downstream process machines.

Therefore, for post-processing machines, a method was adopted in which the assembled plate-like materials were once piled up, stored, and then fed, which required extra manpower and storage space.

The present invention eliminates conventional inefficient manual work, and connects directly to pre- and post-process machines, saving unnecessary manpower and storage space, and improving filling rate and work efficiency.
Furthermore, in order to prevent a drop in yield, a conveyor that rotates at high speed is linked with a plate-shaped object receiver and a drive body that rotates at low speed to convey subsequent plate-shaped objects that are fed in at irregular intervals. On the conveyor, the plate-shaped object is held between the plate-like object holder and the driving body, and is quickly brought close to the preceding plate-like object by the rotational force of the driving body. It is constructed so that it can be assembled into a group of plate-like objects arranged in a continuous manner by reliably bringing them together while eliminating overlapping and bending.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.
First, its configuration will be explained.

1 is a plate-shaped object S ₁ , S ₂ , S ₃ , ... A plurality of belts 4 are suspended between a starting end pulley 2 on the insertion side and a terminal end pulley 3 arranged oppositely at an appropriate interval, and
A transport conveyor rotates at a speed of _{120 to 150} m/min. It is a plate-shaped object holder, and its entire length is divided into appropriate groups of the same length, for example, 14 groups, and each group R ₁ , R ₂ , ... R ₁₃ , R ₁₄ is equipped with a fluid cylinder C ₁ , C ₂ ,...C ₁₃ and C ₁₄ are connected.

5 is a plate-shaped object receiver R and a plate-shaped object on the conveyor 1
S ₁ , S ₂ , S ₃ . . . Roller conveyor-like upper plate-like object holder installed opposite to the conveying surface; 6 is the outer periphery of the belt 7; the lower surface of the roller 8 of the upper plate-like object holder 5 It is pressed to the upper surface, and the lower surface of the outer periphery of this roller 8 is pressed against the plate-shaped object.
S ₁ , S ₂ , S ₃ ...In the conveying direction, the conveyor 1
A belt conveyor rotating at a lower speed, e.g. 50-75 m/min, 9 a belt holder for belt 7, 10
11 is a feeding conveyor that is rotated at the same speed and in the same direction as the conveyor 1, and 11 is a feeding conveyor that rotates plate-like objects S ₁ , S ₂ , S ₃ ... perpendicular to the conveying direction near the end of the upper plate-like object receiver 5. The stoppers _{L 1 ,} L ₂ ... _{L 13 ,} L ₁₄ arranged in
The plate-like object detectors are arranged at the same intervals as the plate-like object detector L 1 , and the plate-like object detector L ₁ has a fluid cylinder C ₁ and the plate-like object detector L ₂
are connected to fluid cylinders C _{2 . .} . , respectively.

In this embodiment, the belt conveyor 6 and the upper plate-shaped object receiver 5 form a driving body, and the belt 7 of the belt conveyor 6 is pressed by the rollers 8, causing the upper plate-shaped object receiver 5 to follow. However, instead of this, it is also possible to employ a belt conveyor or a chain conveyor provided opposite to the plate-shaped object receiver R as the direct driving body.

Further, although the plate-like object holder R is shaped like a roller conveyor, it can also be shaped like a flat plate or a chain conveyor.

Next, the effect will be explained.

In the embodiment shown in FIGS. 1 and 2, plate-shaped objects S ₁ , S ₂ ,
In order to assemble the continuously arranged plate-like objects S ₁ , S ₂ , S ₃ , ... into a group by bringing together the end surfaces of S 3 , ..., the conveyor ₁ , belt conveyor 6, The feed conveyor 10 is rotated and the upper plate-like object receiver 5 is driven.

Next, the plate-like objects S ₁ , S ₂ , S ₃ , . . . are sequentially fed to the feeding conveyor 10 at arbitrary intervals.

For convenience, the first plate-shaped object S ₁ is connected to the plate-shaped object receivers R ₁ and R ₂
...It has a length of approximately 3 out of 14 groups of R ₁₃ and R ₁₄ , and this plate-like object S
1 passes through the plate-like object detectors L ₁₄ , L ₁₃ , L ₁₂ ... in sequence, but since the plate-like object detector detects only from the end, the plate-like object detector L ₁ at the end is activated. Then, L ₂ and L ₃ corresponding to the length of the plate S ₁ are activated.

Another method is to set the plate-like object detector to always detect the plate-like object, and send only the rising signal to the plate-like object receiver from the terminal end of the plurality of plate-like object detectors. It may also be possible to output according to the order of arrangement.

The plate-like object detectors L ₁ , L ₂ , L ₃ are fluid cylinders C ₁ ,
Output a rising signal to C ₂ and C ₃ , and this fluid cylinder
Plate-shaped object receivers R ₁ , R ₂ , R ₃ connected to C ₁ , C ₂ , C ₃
brings the plate-like object _S1 into contact with the upper plate-like object receiver 5.
(See Figure 3) Subsequently, the subsequent plate-like object _S2 reaches the plate-like object detector _L4 adjacent to the plate-like object detector _L3 , and activates the plate-like object detector _L4 . For convenience, this plate-shaped object S ₂ is approximately two of the plate-shaped object receivers R ₁ , R ₂ . . . R ₁₃ , R ₁₄
Since it has the length for the group, the adjacent plate-like object detector _L5 is also activated.

Therefore, plate-shaped object detectors L ₄ and L ₅ are fluid cylinders.
Output a rising signal to C ₄ and C ₅ , and this fluid cylinder
The plate-like object receivers R ₄ and R ₅ connected to C ₄ and C ₅ bring the plate-like object S ₂ into contact with the upper plate-like object receiver 5 . (See Figure 4) The same operation is repeated for the plate-like objects S ₃ , S ₄ ..., and the plate-like objects S ₃ , S ₄ , etc. inserted at irregular intervals are
_S5 sequentially operates the plate-like object detectors _L6 , _L7 ... _L13 , _L14 , outputs a rising signal to the fluid cylinders _C6 , _C7 ... _C13 , _C14 , and detects the plate-like object. The tools R ₆ , R ₇ ... R ₁₃ , R ₁₄ abut against the upper plate-like object holder 5. (See Fig. 5) On the other hand, the plate-like object S 1 which is in contact with the upper plate-like object receiver 5 and is held between the plate-like object receiver R and the upper plate-like object receiver ₅ ...
In _S5 , the upper plate-shaped object receiver 5 is driven, so
Due to the rotational force, the plate-like object _S1 is transferred to the stopper 11 and stopped, and the following plate-like objects _S2 ... _S5 sequentially bring their end faces together, forming a group of plate-like objects arranged in a continuous manner. It is compiled into. (See FIG. 6) The assembled plate-like objects S ₁ ...S ₅ are carried out perpendicularly to the conveying direction by appropriate means, or are moved straight by opening the stopper 11, and are supplied to the post-processing machine.

As described above, according to the present invention, the upper plate-shaped object holder rotated at low speed is linked to the conveyor that rotates at high speed, and the plate-shaped object holder is divided into groups as appropriate, and each of the plate-shaped object holders is divided into groups. Connecting to each fluid cylinder, a plate-like object detector is arranged at the same interval as the fluid cylinder, and according to the arrangement order from the end,
Since the plate-like objects are detected one after another and a rising signal is output to the fluid cylinders placed on the back side of each plate-like object, subsequent plate-like objects fed at irregular intervals are moved ahead by the conveyor. The plate-like object is transported at high speed to a plate-like object detector adjacent to the plate-like object detector that detected the plate-like object.

The plate-shaped object transported at high speed to the adjacent plate-shaped object detector is moved to the upper plate-shaped object holder and the plate-shaped object holder in close proximity to each other by the respective fluid cylinders arranged below the plate-shaped object. Due to the rotational force of the upper plate-like object holder, which is held between the tools and rotated at low speed, the plate-like objects are quickly and reliably arranged in a continuous manner by sequentially bringing together the end surfaces while eliminating overlaps, bends, etc. It is something that can be assembled into a group of things.

Therefore, the work of once stacking and storing assembled plate-like materials has been completely eliminated, and furthermore, the widening of gaps, overlapping, bending, etc. that occur when directly connected to front and rear processing machines has been eliminated. Since it can be assembled, it is possible to not only save extra manpower and storage space, but also improve work efficiency and filling rate, and prevent a decrease in yield.
