DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding and tensioning device for a wooden hand machine.

[0002]

2. Description of the Related Art As is well known, a typical construction of a hand-held machine (tebata) which has been used for weaving high-quality fabrics such as sewable and woven fabrics since ancient times is shown in FIGS. It is as shown in FIG.

That is, in the hand-held device 1 shown in FIG.
The warp 3 is wound and attached to the main body of the hand machine by a mandrel 4 having a square cross section called a "square core". In this state, the warp 3 is divided into upper and lower parts by the vertical movement of the heald 5, and an opening is formed. Are repeatedly woven by a reed, and the woven fabric 8 is sequentially wound around a tsumaki 7.

A gear 9 called "chrysanthemum" is axially mounted on the mandrel 4 of the shredder 2, and the gear 9 is fixed by a stopper 10 called a "stopper". Do not rotate in the direction in which the warp 3 is sent out.

A ratchet wheel 13 of a winding device 12 shown in FIG. 2 is fixed to the mandrel 11 of the tsumaki 7, and a ring 14 circling the ratchet wheel 13 is rotatably mounted on the ratchet wheel 13. The handle 14 is provided integrally with the ring 14.

A pawl 16 provided on the handle 15 and a detent 17 (see FIG. 1) provided on the main body of the hand machine are fitted on the teeth of the ratchet wheel 13 with the pins serving as fulcrums, respectively. Handle 1 to wind up
By turning the knob 5 forward, the pawl 16 rotates the splint 7 and the detent 17 allows only the handle 15 to be returned in the opposite direction, and the pawl 16 and the detent 17 swing and fit. Is rotated only in the direction in which the woven fabric 8 is wound up, so that the tension of the warp yarn 3 does not reversely rotate the weaving tree 7 during weaving.

Japanese Utility Model Laid-Open Publication No. 55-151886 discloses a warp sending device for a loom. In the warp sending device, a torque is applied to a shredder by applying a reversing force in the direction of rewinding the warp. The drive system of the motor is provided with a reverse rotation restraining gear (ratchet mechanism) for restraining the rotation reverse rotation force and a separating member, and the tension of the warp is applied by the restraining force (reverse rotation force) of the torque motor generated by pulling out the warp. Further, by providing an easing roller that swings in the front-rear direction, a change in length due to the opening movement of the warp is compensated to keep the warp tension constant.

[0008]

In the above-mentioned conventional hand machine, the weaving position advances as the fabric 8 is being woven.
The warp 3 is sent out by releasing the stopper 10 fixed to the mandrel 7, and thereafter, the ratchet wheel 13 connected to the mandrel 11 of the tsumaki 7 is turned with the handle 15 to rotate the tsumaki 7, and the woven fabric 8 is sequentially passed through the tsumaki 7. There was a problem that a very complicated manual work of winding up had to be performed.

Also, the woven fabric 8 is sequentially wound around the tsumagi 7 and the diameter of the tsumagi 7 increases, so that the handle 1
The force applied to No. 5 must be increased accordingly, and there is a problem that maintaining the warp tension constant requires skill.

Further, when the handle 15 is operated to wind up the woven fabric 8, the force applied to the handle 15 is adjusted to increase the warp 2.
The tension applied to the handle 15 is adjusted, but the force applied to the handle 15 varies from person to person, and even if the same person, the difference occurs due to the mood during weaving, and the woven fabric lacks uniformity. ,
There was also a problem that defective products appeared.

The warp sending device disclosed in the above-mentioned publication has a complicated structure that separates the easing roller, the ratchet mechanism, and the ratchet mechanism, in addition to the torque motor and the gear that transmits the power of the torque motor to the shredder. It is necessary to provide such a heavy-duty device to a conventional hand-held device whose main body is made of wood, and it is necessary to be strong enough to withstand the weight of the heavy-duty device. Such devices cannot be attached to conventional hand machines.

Therefore, the inventor of the present invention has made a technical task to eliminate the above-mentioned problems of the conventional hand-held device with a simple and lightweight winding device, and has repeatedly conducted research and experiments in an attempt to materialize the problem. As a result, if a torque motor and a worm gear are combined, it can be applied to hand machines whose wooden body is made of wood. Even if the woven fabric is wound up every time, the warp is always tensioned with the same tension. The present invention has achieved remarkable knowledge that the above-mentioned technical problems can be achieved.

[0013]

The technical problem can be solved by the present invention as described below.

That is, in the winding and tensioning device for a wooden hand machine according to the present invention, a warp wound in a shredded manner is passed through a heddle and a reed and tied to a tsumaki tree, and the heddle is moved up and down while the warp is stretched uniformly. bisecting vertically to form an opening to insert the weft yarn through the shed to the opening and, the weft yarn at the winding tension device wooden hand machine takes successively up the up fabric weave woven by implanting in the reed in Tsumaki, the torn A first worm wheel is axially mounted on a mandrel of the first worm wheel, and a first worm meshed with the first worm wheel is connected to a motor via a gear.
