JPS58177838A - Lift/convey device of veneer - Google Patents

Abstract

PURPOSE:To lift and convey a veneer always a fixed position by driving a sliding piece in the uppermost veneer during the lift/convey process of the veneer in the production line of the plywood. CONSTITUTION:A veneer 11 with the needle 8 of a sliding piece 3 driven in it is lifted, and its front end surface is coupled with a dead roller and the rear is coupled with a press roller 28. By an operation of a cylinder, a rod is lifted to away an arm 22 in an arrow direction, and a roller 14 is brought into contact with the lower surface of the veneer 11 so as to pinch the veneer 11 together with the dead roller and also remove the needle 8 from the veneer 11. Then, the roller 14 is driven to convey the veneer 11 to the next process. After the conveyance is completed, the power transmission to the roller 14 is stopped, the rod is extended to return the roller 14 to its original position, and the sliding piece 6 is descended to repeat the same cycle.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for pulling up and feeding out veneers used in a veneer supply process in a plywood manufacturing line.

Conventionally, products used for this type of process include those that pull up and convey laminated veneers one by one using vacuum suction, and those that transport laminated veneers on the table of a lifting device such as an elevator around the outer periphery of a roller. A device is used that is carried out by rotational engagement using a nail-shaped protrusion provided therein. In the case of vacuum suction, if there are cracks in the veneer, there will be irregularities, and in the case of rotary engagement of the protrusions, there will be extreme unevenness in the stacking height of the laminated veneers on the same elevator. There were restrictions such as making it unsuitable. Therefore, the present invention has the following advantages:
The supply of veneers for each row on the table can be stacked without using any special care, and the veneers are always pulled up to a fixed position and carried out, so there is no trouble in moving the veneers. Since there is no need for a corresponding lifting operation of the table, there is no cause for trouble in the interlocking operation of vertical movement and horizontal movement, and an efficient and economical carrying-out device is provided.

The veneer lifting and unloading device (hereinafter referred to as the present device) of the present invention will be described based on an embodiment. A required number of clevis-shaped fluid pressure cylinders 3 are attached to the cross beam 2 at the upper part of the frame l. A guide bar 5 of the required width is fixed to the lower end of the rod 4, and the guide bar 5 is attached at the required pitch. The fixed frame 7 is assembled by engaging the IT mover 6 in a vertically slidable manner.
We are guiding you along the 81m length. * Two screw-shaped needles 8 are implanted in the lower end surface of the m child 6, and a stopper 9 is installed in the lIIM song.
A rubber seat 10 is attached to the lower surface of the stopper 9 to reduce the impact when the guide bar 5 and the stopper 9 come into contact with each other.

Driving into a veneer by the slider 6 will be explained with reference to Fig. 3. When the rod 4 of the hydraulic cylinder 3 is lowered by a predetermined stroke for each day, the guide bar 5 fixed to the lower end of the rod 4 is also lowered together. The slider 6 whose top part is fixed on the upper surface of the guide bar 5 descends with a certain speed and positional energy, and the needle 8 on the lower end surface of the slider 6 is driven into the friend veneer ■ stacked in each row. It will be done.

Since the slider 6 is independently and freely locked to the guide bar 5, the driving force can be easily adjusted by correcting the weight of the slider 6 or the descending speed of the rod while checking the hydraulic cylinder 3. Can be adjusted. Moreover, the third
As shown in the figure, the needle 8 is attached to the single plate l regardless of the stacking height of each row. can be typed into. When pulling up aMst, the rod 4 is raised and the guide bar 5 integrated with it is pulled up.
First, the stopper 9 on the top of the slider 6 engaged with the slider 1 is engaged with the guide bar 5 and pulled up, and the rod 4
At the rising end of , the sets 11 raised 41 from each row are aligned at the same height.

To explain the configuration of a part of the roller that carries out the pulled up veneer 11, 11211! A dead roller 13 is rotatably supported on the fixed frame 7 by a bearing 12 so that the upper surface of the forward end of the veneer 11 that has been pulled up so as to be raised to I+ comes into contact with the veneer l! Dead roller 1 contacts from the bottom surface.
The live roller 14, which brings out the veneer 114t11 by sandwiching it with the roller 3, is driven as follows. The power from the continuously variable transmission $115 is input to the clutch 17 via the reducer 16, and is transmitted from the clutch output shaft side sprocket 18 to the input side sprocket 20 of the intermediate shaft 19 via the chain 21, and then the intermediate shaft A live roller 14 is rotatably supported on the other end of an arm 22 whose one end is rotatably supported by an arm 19, and a sprocket 23 is secured to the shaft end of the arm 22, which is secured to the output side of the intermediate shaft +9. Power is transmitted from 24 through a chain 25 to drive the live roller 14. The live roller 14 is rotatably engaged with a rod 27 of a fluid pressure cylinder 26 at its left and right shaft portions so as to be able to swing around the axis of the intermediate shaft 19, and the fluid pressure cylinder 26 is swingably attached to a fixed frame. 7 is locked. Therefore, during the temporary pulling up of IIl, the live rollers 14& are placed in a standby position, moving around the veneer lifting space so as not to interfere with the veneer pulling up.

With the above configuration, the veneer 11 can be pulled up and carried out if! To explain with reference to Figure 1, the veneer 11 into which the needles 8 of the slider 3 shown by the temporary line have been driven is pulled up to the position shown by the solid line, and its top surface is locked to the dead roller I3. The part is a presser roller 2 that prevents flapping.
It is locked at 8. Thereafter, by operating the fluid pressure cylinder 26, the rod 2f is pulled up, and the arm 22 is swung in the direction of the arrow about the axis of the intermediate shaft 19, thereby moving the live roller I4.
is brought into contact with the underside of the veneer 11, and while the veneer 11 is held together with the dead roller 13, the needle 8 is removed from the veneer ■ by swinging at the same time, and then the clutch is engaged to drive the live roller 14 and the veneer 11 is removed! 1 is carried out to the next process. After the unloading is completed, the clutch is disengaged to stop power transmission to the live roller 14, the rod 27 of the hydraulic cylinder 26 is extended to return the live roller 14 to its original position, and the slider 6 is lowered to perform the same operation. The cycle is repeated and the veneers are automatically and continuously pulled up and carried out.

As described above, the present invention does not require the use of a complicated mechanism, has a simple structure, and is an economical unit with high work efficiency that can continuously transport laminated veneers of varying heights in multiple rows at once. The present invention provides a board pulling device.
