Description

Detailed Description of the Invention (Object of the Invention) The present invention is directed to a continuous strip of veneer veneer cut by veneer lace, or a veneer veneer that is partially or completely broken in the fiber direction due to water cracking of raw wood. The main target is slightly connected continuous or discontinuous veneer veneers, which are automatically wound onto a winding reel to form thick rolls, which are then stored on a storage shelf. This relates to an automatic feeding device in a veneer rewinding machine, which is used to store the veneer, take it out as necessary, and continuously rewind and supply it to subsequent processing equipment, such as a cutting machine or a dryer. The purpose of this is that in the process of unwinding this type of spool with large water cracks in the fiber direction, the movement of the veneer veneer onto the unloading conveyor is frequently disrupted. Conventionally, a worker constantly monitored the feeding operation, and each time a breakage occurred due to water cracking, the worker would manually feed it out again. This required a large number of workers and reduced process efficiency. In order to eliminate the drawbacks that were caused by the low-level design, the unloading conveyor and supports such as sticking rollers are constantly brought close to the outer periphery of the rolled bobbin, and the presence or absence of the veneer veneer fed out onto the unloading conveyor is constantly monitored. It is detected by a single plate detector, and each time the feeding operation is interrupted, a feeding mechanism such as a stabbing roller is brought into contact with the outer periphery of the rolled ball for a certain period of time, so that the automatic feeding operation can be repeatedly performed again. The aim was to enable automatic rewinding of rolled balls by unmanned operation.

(Structure of the Invention) As illustrated in an example of its implementation, the present invention includes a conveyor such as a chain 2 with rollers, a belt, etc., which is extendably installed so as to cover the lower half of the outer circumference of the rolled ball 1;
A rewinding conveyor 3 is rotatably installed in contact with the rear portion of the upper half of the outer circumference of the rolled ball 1; In a veneer rewinding machine consisting of a feeding mechanism such as a sticking roller 5 or a suction roller, which is installed so as to be freely drawn out on a carrying out conveyor 4 by adhesion or adsorption, the carrying out conveyor 4 and a support 6 such as a sticking roller 5 are connected to each other. A rolled ball detector 7 is installed on the support 6 and connected to a moving mechanism 8 so as to be able to follow and approach near the outer circumference of the rolled ball 1 at all times, and the veneer veneer 9 fed out onto the unloading conveyor 4 A veneer detector 10 is installed on the unloading conveyor 4 so that whenever the unwinding operation is interrupted by detecting the presence or absence of the roll, a sticking roller 5 or the like is brought into contact with the outer periphery of the wound ball 1 for a certain period of time to enable the unwinding again. This is an automatic feeding device in a veneer rewinding machine, which is connected to an operating mechanism 11 such as the pricking roller 5 through a timer 12.

That is, in the present invention, a rolled ball 1 wound around a reel 14 is moved onto a rail member 13 at the unloading end of a storage shelf that forms an unwinding place, and is temporarily fixed thereon, and then the outer periphery of the rolled ball 1 is fixed. A rotating support 15, which fixes the end of a conveyor such as a chain 2 with rollers and a belt, which is installed to extendably cover the lower half area, is actuated by an operating mechanism 16 such as an air cylinder to wind it. The winding ball 1 is wound around the winding ball 1, and the unwinding conveyor 3 is activated by an operating mechanism 17 such as an air cylinder and comes into contact with the winding conveyor 3 near the rear of the upper half of the outer periphery of the rolled ball 1, thereby transmitting the unwinding power from the outer periphery. (See Figure 1).

Next, when preparations for the rewinding operation are completed, the drive mechanism 1 consisting of the motor of the rewinding conveyor 3, etc.
8 in conjunction with the post-processing device, and integrally supports the delivery mechanism such as the carry-out conveyor 4 and the sticking roller 5, so that it can be moved to follow the change in outer diameter as the rolled ball 1 is unwound. A moving mechanism 8 consisting of a forward/reverse motor and the like of a support 6 having a reciprocating mechanism such as a chain 20 suspended and mounted on the rail member 19 also operates the same. In such a case, the winding ball detector 7, which consists of a photoelectric switch or the like installed on the support body 6, moves toward the winding ball 1 until it approaches the outer periphery of the winding ball 1, while maintaining an appropriate interval at all times. The moving mechanism 8 is automatically controlled by the winding ball detector 7 to follow the change in the outer diameter of the winding ball 1 as it is unwound. Furthermore, the feeding mechanism such as the stabbing roller 5 that has reached the vicinity of the outer circumference of the rolled ball 1 due to the movement of the support body 6 is moved by the delivery conveyor 4.
An electric signal sent by a veneer detector 10, which is constructed of a photoelectric switch or the like installed above, indicating that the veneer veneer 9 has not yet been delivered onto the carry-out conveyor 4, is sent to the sticking roller via a timer 12 such as a timer. 5
The unwinding mechanism is transmitted to the actuating mechanism 11 such as an air cylinder that comes into contact with the winding ball 1 side, and is activated for a certain period of time. The device is such that the leading end rotates to the place of the feeding mechanism such as the pricking roller 5 during that time period, and the veneer veneer 9 is forcibly fed out from there onto the carrying out conveyor 4. (See Figure 2).

Next, there is a part 1a in the bobbin 1 that is broken all along the fiber direction due to water cracking of the raw wood, so when the broken part 1a rotates to the unwinding place, it will be on the unloading conveyor 4. The unwinding operation of the veneer veneer 9 is interrupted, and the roll 1 is simply idling on the unwinding conveyor 3. When the device 10 detects that the unwinding operation of the veneer veneer 9 has been interrupted, it can immediately start the unwinding operation again (see FIG. 3).

When the unwinding operation of the veneer veneer 9 is interrupted due to the arrival of the breaking point 1a, an electric signal from the veneer detector 10 is transmitted through a timer 12 set to a time period of about 1 or 2 rotations of the winding ball 1. operating mechanism 11
Therefore, the operating mechanism 11 brings the feeding mechanism such as the sticking roller 5 into contact with the outer periphery of the rolled ball 1 again for a certain period of time, sticks or attracts the tip of the veneer to it, and places it on the carry-out conveyor 4. Sequentially veneer veneer 9
The device is designed to repeat the action of feeding out each time (see Fig. 4).

In the figure, 2a is a chain 2 with rollers, a weight that applies a desired tension to a conveyor such as a belt, or a tensioning device such as an air cylinder or a rope winder in place of this, and 4a is a tension device such as a rope winder. An adjustment device 5a is a release device for sticking, adsorption, etc. such as a sticking roller 5, and 13a is a rail member 1 on which the rolled ball 1 is mounted.
This is a rail member that returns the empty reel 14 connected to the reel 14 to the winding side.

(Effects of the Invention) As described above, the present invention allows the unloading conveyor 4 and the support body 6 such as the sticking roller 5 to follow and approach the vicinity of the outer circumference of the wound ball 1 at all times, and the unrolled ball is unwound onto the unloading conveyor 4. The presence or absence of the veneer veneer 9 is constantly detected by a veneer detector 10, and each time the feeding operation is interrupted, the feeding mechanism such as the sticking roller 5 is brought into contact with the outer periphery of the rolled ball 1 for a certain period of time, and the automatic operation is resumed. By configuring it so that the feeding operation can be performed repeatedly,
It has completely eliminated the major drawbacks of conventional equipment, such as constant monitoring of the feeding operation by workers and manual re-feeding work, which required a large number of workers and had low process efficiency. This is an extremely effective invention that has made it possible for the first time to automatically rewind a rolled ball by unmanned operation.
