Description

Detailed Description of the Invention (Object of the Invention) The present invention is directed to the production of veneer veneers that are cut and discharged by veneer lace, and in particular to discontinuous unprocessed small mountain veneers that are discharged during the rough peeling process and the core peeling process. , or a small mountain veneer that has been processed to correct curls, remove irregular edges, and be shaped to size, and feed a winding medium such as a winding tape onto the top surface of the small mountain veneer. This invention relates to an improvement of a winding and rewinding device that utilizes a winding medium of small mountain veneer that is wound together to form a rolled ball. The winding and rewinding device using a winding medium disclosed in No. 55-46850, Method for processing veneer veneer, etc., is capable of feeding out a winding medium made of a wire material such as thread during winding and unwinding the winding medium. To collect the media, the tip of the winding medium is manually wound around a reel several times in advance, and then it is automatically fed out from the bobbin by following the rotation of the reel, and then wound into a bobbin together with small and medium veneers. Conventional devices for collecting the winding medium from the rolled ball by manual means, which are fed out during unwinding, rely on manual labor to a large extent, and the winding force and unwinding force are too low. Since automatic adjustment was not possible, we improved the biggest obstacle to automatic adjustment, labor saving, and stabilization of the winding and unwinding process of small and medium veneers using conventional equipment. First, the small and medium veneers that are brought in are automatically wound onto a reel by a reeling machine equipped with a winding conveyor, and the winding medium is placed on the top of the small and medium veneers during the winding process by a winding motor such as a torque motor. The cassette drive mechanism automatically unwinds the material from the cassette, and the automatic adjustment of its rotational force safely brakes it while simultaneously winding it into a spool, and then taking it out to the unwinding location. The winding medium is unwound by an upper surface support conveyor, which is used to unwind the bobbin.The winding medium is collected safely into the cassette by the automatic adjustment of the rotational force of the unwinding cassette drive mechanism such as a torque motor. The object of the present invention is to provide a new type of winding and rewinding device that utilizes a winding medium.

(Structure of the Invention) As an example of its implementation is shown in the drawings, the present invention is directed to discontinuous veneers that are discharged during the rough peeling process and the core peeling process among the veneer veneers that are cut and discharged by the veneer lace in the previous step. Either the small and medium veneers are conveyed as they are in the direction perpendicular to the fiber direction, or the curls of the small and medium veneers are further corrected using a tenderizer, etc., and then cut to size using a veneer clipper and a waste divider. The small and medium veneers 2a are separated and assembled into a continuous group of small and medium veneers by a follow-up conveyor, a telescopic conveyor, etc., and after converting the intermittent conveyance mode to a continuous conveyance mode, the small and medium veneers 2a are delivered onto the winding conveyor 1. 1, rotatably supported on the winding place base, and installed at the tip of the winding conveyor 1 so as to be able to vibrate freely.

A reeling machine with an automatic winding device is provided, which includes an arm mechanism 50 that can be freely wound around J-/L'4a. Further, at the winding place base, a winding medium 7a such as a winding tape stored in a reel 6a is placed on the upper surface of the small and medium veneer 2a which is continuously wound by the reeling machine. However, the cassette 6''

A is attached and its rotational force automatically feeds out the winding medium 7a stored in the force cellar 6a, and once the winding medium 7a is wound into the bobbin, the rotational force is applied. It is equipped to automatically adjust the braking force for feeding.

Next, the rolled ball 9a wound by the reeling machine
Once stored in the storage deck 10, it is taken out to the unwinding place 11, and the small width single 1fZb can be continuously rewound from the rolled ball 9b. J-/l/4

Alternatively, an unreeling machine 12 composed of an upper surface support conveyor such as a suction conveyor may be installed in a vibrating manner, and the upper surface support conveyor may be brought into contact with the outer circumference of the rolled balls 9b by the unreeling machine 12. There is a small unwinding process on the bottom side of the screen.

The width veneer 2b is stuck or suction-supported and then transferred to a veneer dryer 13 for a subsequent process, for example, a drying process as shown in the figure.
etc., and are transported continuously.

Further, as the unreeling machine 12 unwinds the narrow veneer 2b, a force is applied again to the winding medium 7b =, so that the winding medium 7b can be wound into the set 6b.
A rewinding cassette drive mechanism 8b such as a torque motor is attached to the rewinding cassette drive mechanism 8b, and its automatically adjustable rotational force is used to control the force cellar) 6.
It is a device that automatically and safely winds up the winding medium 7b1 in the winding medium 7b1.

Incidentally, in the upper row of the storage deck 10 for the above-mentioned rolled balls 9a, the empty glue ZV4C rewound at the rewinding place 11 is returned to the winding place base, temporarily stored, and then taken out again and wound. Of taking! In addition to being used cyclically as J-zL/4a, the winding medium 7a wound into the winding ball 9a at the winding place base is rolled up by the cassette 6a containing the winding medium 7a upon completion of the winding operation. The rewinding cassette is removed from the rewinding cassette drive mechanism 8a, is integrally fixed to a suitable location on the rolled balls 9a, and is sent to the rewinding location L via the storage deck 10, where the rewinding cassette is driven at the rewinding location 11. The cassette 6b of the winding medium 7b collected at the rewinding station 1 is loaded into the rewinding mechanism 8b as the winding medium 7b, and is transferred from the rewinding cassette drive mechanism 8b upon completion of the rewinding operation. The empty reel 4C is removed and fixed to an appropriate location on the empty reel 4C during the return process, and then passed through the storage deck 10 and reinstalled as the winding medium 7a in the winding cassette drive mechanism 8a at the winding place base. Similar to the reels v4a and 4b, the winding fi body 7a,
7'o is also used cyclically.

(Effects of the Invention) As described above, the present invention automatically I
J-Iv4a, and the winding medium 7a is automatically fed out from the cassette 6a by a winding cassette drive mechanism 8a such as a torque motor onto the upper surface of the small mountain veneer 2a during the winding process, and its rotation An unreeling machine consisting of an upper surface support conveyor rewinds the rolled ball 9b, which is safely braked by an automatic force adjustment action, is wound onto the rolled ball 9a, and then taken out to the unwinding place L. 12, and the winding medium 7b that is simultaneously rewound is safely collected into the cassette 6b by the automatic adjustment of the rotational force of the rewinding cassette drive mechanism 8b such as a torque motor. Since this is a new type of winding and rewinding device that uses a take-up medium, this type of conventional device manually wraps the leading edge of the take-up medium around a reel several times in advance, and then follows the rotation of the reel. All process operations depend on manual labor, such as unwinding from the bobbin, winding it together with a small veneer into a bobbin, and recovering the winding medium that is unwound from the bobbin by any means. This eliminates all of the biggest obstacles to automation, labor saving, and stabilization of the winding and unwinding of small mountain veneers using conventional equipment of this kind, which has a high proportion of winding and unwinding forces and cannot automatically adjust the winding force and unwinding force. With the completion of the present invention, the streamlining of the winding and unwinding process of Koyama veneer has been significantly advanced, and it is an invention with extremely remarkable implementation effects.
