Abstract

PURPOSE:To quickly transport a succeeding plate material fed at unfixed intervals to be brought close to a preceding plate material by associating plate material guide and a low-speed rotating driver with a suction transport conveyer. CONSTITUTION:Low-speed rotating plate material guide means are associated with a high-speed rotating suction transport conveyer 1. The plate material guide means R1- R14 are divided and classified into suitable groups, and the respective groups are connected to fluid pressure cylinders C1-C14. During transport operation, an elevation control board 30 computes a pulse signal of a rotation pulse generator 18 showing the length of the individual plate material supplied to the conveyer 1, a pulse signal of a rotation pulse generator 23 showing the travel of the individual plate materials, and an electric signal of a console panel 29 showing the distance from the reference point of the travel measuring start to the vicinity of the terminal of the plate material guide means. According to the operation result, a descend signal is output to fluid pressure cylinders C1-C14, so that a succeeding plate material fed at unfixed intervals is transported at high speed to the vicinity of the terminal of the plate material guide means adjacent to the plate material guide means where a preceding plate material is placed at a plate material receive means 8 by the suction transport conveyer 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves feeding a plate-shaped object, particularly a sized veneer veneer from which defective parts have been removed, to a suction conveyor at irregular intervals, and transporting the drive body and the plate-shaped object to the suction conveyor. By linking the guide tools, the following plate-shaped object is quickly brought close to the preceding plate-shaped object on the suction conveyor, and the drive is rotated at low speed while being held between the drive body and the plate-shaped object guide. This invention relates to a device for assembling plate-like objects that uses the rotational force of a body 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 inserting individual plate-shaped objects that have been piled up irregularly into a continuous array of plate-like objects by hand each time they are supplied to a subsequent process machine. The method adopted was pregnant.

However, manual work is inefficient and limits processing power.9
Instead, when inserted, adjacent plate-like objects tend to come loose or the gap widens 9, which causes insufficient drying of overlapping parts and a decrease in filling rate in post-processing machines.

In addition, conventional devices that do not involve manual labor are capable of assembling a group of plate-like objects in a continuous manner by transporting and stopping the preceding plate-like objects using a clutch brake, and then bringing the following plate-like objects together one after another. method was adopted.

However, variations occur when the clutch brake is used to start and stop, and as the conveyance speed increases, the variations tend to increase.Also, the impact force at the time of collision increases, so it is necessary to adjust the When used in direct connection, the assembled plate-like objects have wide spacing 9 and overlapping 9
, bends 9 in the front and rear edges occurred, and the yield was reduced, and the filling rate and work efficiency of the post-processing machines were significantly reduced.

In addition, in order to reduce the variation at startup and stop, reduce the impact force at the time of collision, and prevent widening of the gap, bends, bends, etc., it is important to limit the conveyance speed to a low speed. becomes smaller, and if it is directly connected, it will reduce the throughput of the processing machines before and after the process.

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

The present invention eliminates the conventional inefficient manual work, connects it directly with the pre-processing machine, reduces unnecessary manpower and storage space, improves the filling rate and work efficiency, and prevents a decrease in yield. By linking the plate-like object guide to the suction conveyor that rotates at high speed and the drive body that rotates at low speed, subsequent plate-like objects fed in at irregular intervals are transferred to the suction conveyor and It is held between the plate-like object guide and the driving body, and is quickly brought close to the preceding plate-like object by the rotational force of the driving body, and then held between the plate-like object guide and the driving body, and crossed by the rotational force of the driving body. The structure is such that the parts such as 81B9 and the like are not removed, but are brought together in a precise manner so that they can be assembled into a group of plate-like objects arranged in a continuous manner.

Therefore, during the conveyance, the detection roll 17 driven by the plate-shaped objects S1, S2,... rotates the slit plate 20i, and the rotating pulse generator 18 rotates the detection loaf 17(]l- A pulse signal proportional to the length of the plate-shaped objects S!, S2, . . . is output.

For convenience, the A-A line and light beam detector 28 are connected to the plate-shaped object guide R.
Since the length of the first plate-like object S1 is set to 2.81, the correction circuit 31
The descending region of the plate-like object guide R is rounded up to an electrical signal proportional to 1, and the descending region setting circuit 32 sets three groups R1, R2, and R8.

Also, the operation panel 29 indicates the distance, that is, IIJ? Since an electric signal proportional to 14/ is outputted, the moving distance calculation circuit 33 sets an electric signal proportional to 14/.

On the other hand, when the tip of the plate-shaped object s1 passes, the light beam detector 28 outputs an electric signal to start measuring the length to the rotational pulse generator 23, and the rotational pulse generator 23 outputs a pulse signal proportional to the distance traveled.

(See FIG. 7) The assembled plate-like objects SL, .

Incidentally, in the case where a pulse signal proportional to the moving distance in the moving distance calculating circuit 88 and the moving distance of the rotary pulse generator 2B is captured in a time-limited manner, Vζ and [lower timing setting circuit 84 sets the instantaneous timing] A falling signal is output to C11..., C14.

As described above, according to the present invention, the plate-shaped object receiver rotated at low speed is linked 6 to the suction conveyor that rotates at high speed, and the plate-shaped object guide is divided into groups 6 as appropriate. When connecting each to the individual fluid cylinders, the length 6 of each plate-like object fed to the suction conveyor during feeding is VcjIi.
The pulse signal of the rotary pulse generator that indicates the moving distance of each plate-shaped object, the pulse signal of the rotating pulse generator that indicates the moving distance of each plate-shaped object, and the pulse signal of the rotating pulse generator that indicates the distance from the moving distance measurement start point to the vicinity of the end of the plate-shaped object guide An electric signal is calculated in the lift control panel and outputs a descending signal to the fluid cylinder connected to the plate-shaped object guide, so subsequent plate-shaped objects fed at irregular intervals are preceded by the suction conveyor. The plate-like object is conveyed at high speed to near the end of the plate-like object guide adjacent to the plate-like object guide placed on the plate-like object receiver.

Furthermore, the plate-like object that has been transported at high speed to the vicinity of the end of the three adjacent plate-like object guides is placed above it! The broken plate-like object guide and the plate-like object holder are held in close proximity to each other,
Due to the rotational force of the plate-shaped object holder that rotates at low speed, it overlaps,
It is possible to sequentially assemble end faces and ends into a group of plate-like objects arranged in a continuous manner, quickly, while eliminating bends and the like.

Therefore, the work of once stacking and storing assembled plate-like materials is completely eliminated, and the widening of gaps9, overlapping, bending9, etc. that occur when directly connected to front and rear processing machines are eliminated. Since it is possible to assemble the parts while removing them, it is possible to not only save unnecessary manpower and storage space, but also improve work efficiency and filling rate, and prevent a decrease in yield.
