Description

Detailed Description of the Invention [Industrial Application Field] The present invention supports a warp beam and a member through which warp threads have been inserted, and a machine preparation mechanism that enables threading of the warp, which is one of the steps of preparation. This relates to a cradle for use.

[Prior Art] In order to reduce the time required for the above-mentioned work, which will improve the operating efficiency of the loom, the warp beam is attached to the loom and the warp threads are passed through the weaving equipment. Generally, a work procedure is adopted in which the warp threads are inserted in advance through a dropper, a heald frame, and a reed of a warp cut detection device. As a means for that purpose, the applicant has proposed
Japanese Patent No. 243352 discloses a cradle for preparing a mechanism. This receiver has a positional relationship that allows it to support the warp threads of the warp beam in approximately the same shape as the warp delivery shape of the loom. It is composed of a support body that removably supports the threading member, and a warp pulling-out mechanism that pulls out the warp threads of the warp beam all at once via the warp threading member on the support body.

The empty warp beam that has been removed from the loom and the warp threading member through which the warp threads have been passed are supported by the support body, and the leading ends of the warp threads that have been threaded through the reed are collectively connected to a warp pull-out mechanism. In this state, the warp threads are cut between the empty warp beam and the warp threading member, and the warp threads of the full warp beam are connected to the old warp threads on the warp threading member side. Then, the warp thread pull-out mechanism is operated to pull out the warp threads all at once from the full warp beam until the warp knots pass through the reed. As a result, the warp threading, which is one of the preparation steps, is completed for the loom, and upon completion of this, the full warp beam and its warp threading member are stored in a state that supports the warp in the warp delivery shape on the loom. be done. Therefore, the connection between the warp thread threading work, which is one of the preparation steps, and storage are extremely smooth. In addition, the support shape of the warp in this storage configuration is different from the warp delivery shape on the loom where warp threads do not become entangled with each other.
Therefore, there is no friction between the warp threading member and the warp threads, which can cause damage to the warp threads, and the warp threading member, which supports the warp threads in approximately the same shape as the warp delivery shape, is similar to the state in which it is mounted on a loom, so mechanical means cannot be used. There are various advantages such as easy automation of mounting and dismounting.

[Problem to be solved by the invention] However, since warps are passed in units of multiple warps between the many sheets of the reed, there are multiple knots of old and new warps that are aligned approximately in a straight line in the width direction of the warp series. Enter the exile in units.

If a plurality of knots enter the penile space in such a state, the knots will interfere with each other, and the knot with a higher thread density compared to other parts will be pressed more strongly against the bane. This pressing action increases insertion resistance when the knot passes through the reed, and if this insertion resistance is too large, it may lead to thread breakage. In addition, the thread ends extending from the knot tend to get entangled with other warp threads,
This entanglement also increases insertion resistance. In order to reduce the insertion resistance, the worker may remove the reed and shake it, or hold the warp threads little by little and pass them through the reed. It's very difficult to pass.

The object of the present invention is to provide a loom preparation cradle with the various advantages described above, and to provide the cradle with the function of smoothly threading warp threads into the reed at the cradle.

[Means for Solving the Problems] To achieve this, in the present invention, the holder is a reed swivel that is capable of fixedly holding the reed at a standby position on a support body constituting the stand, and that is capable of holding the reed so as to be able to swing in the front and rear directions of the standby position. The moving mechanism was assembled.

[Operation] When the warp threads are drawn through the warp threading member by the warp drawing mechanism, the reed is swung at least when the knots of the old and new warp threads pass through the reed. The dense state of knots arranged in a straight line in the width direction of the warp series is broken up by the warp threads being sorted by the swinging of the reed, and the resistance when passing through the exile is reduced. Furthermore, even if the thread end emerging from the knot is entangled with other warp threads, this entanglement is released by the swinging action of the reed. This allows the knot to pass through the reed smoothly, reducing warp breakage.

[Example] Hereinafter, an example embodying the present invention will be described based on FIGS. 1 to 4.

A guide plate 15 is fixed to the upper surface of the pedestal 14a at the front of the support body 14, which is composed of a pair of symmetrical side frames connected by connecting bars 10.11 and 12.13.

A shaft 18 is rotatably supported between the shafts 7 and 7. A ratchet 23 is rotatably supported by one of the support brackets 17, and is urged to rotate clockwise by a torsion spring (not shown). A winding roller 1 is mounted on the shaft 18.
A number of needles 20 are fixedly attached to the roller 19, and a large number of needles 20 are implanted in a row in the axial direction on the circumferential surface of the roller 19. A ratchet wheel 21 is fixed to one end of the shaft 18 so as to be able to engage with a ratchet 23, and a handle 22 is attached to the outside of the ratchet wheel 21.
are installed and fastened in parallel. This causes the handle 22 to move to the first position.
It can be rotated only in the direction of the arrow in the figure.

Lower horizontal bars 140 on either side of the support body 14
A lever 26 is rotatably supported on the lever 2.
A braking plate 27 for warp beam braking is rotatably supported at the tip of the warp beam 6. A guide post 28 is erected at the rear of the lower horizontal bar 14c corresponding to the rear end of the lever 26, and an adjustment handle 29 is threadedly supported on the guide post 28 so as to be movable up and down. A pair of upper and lower rings 30.31 are fixed to the middle part of the adjustment handle 29 at appropriate intervals, and a forked part at the rear end of the lever 26 extends between the rings 30.31. At the same time, the upper ring 3
A pressure spring 32 is interposed between 0 and the forked portion.

At both left and right ends of the connecting bar 13 constituting the support body 14, hanging bars 25 for suspending the heald frame are supported. Support brackets 35 are tightened and fixed on both sides of the mounting positions of the left and right locking bars 25 to the connecting bar 13.
A support shaft 36 is fastened to each support bracket 35. The support shafts 36 are provided to protrude on opposite sides, and a lever 37 is swingably and non-removably supported at the protruding ends of the two support shafts 36 whose axes are set on the same line. A stay 38 is suspended from the lever 37 and supported. A fixing screw 39 is screwed onto the lever 37 so as to be able to come into contact with the spindle 36, and by tightening the fixing screw 39, the lever 37 can be fixed to the spindle 36. A holding frame 24 for use as a holding member is constructed and supported between the lower ends of both the left and right bearing portions 38 .

A pair of left and right support brackets 48 are mounted on the upper rear end of the pedestal 14a, and a bank roller 49 is rotatably supported between the brackets 48.

When the warp threads of the warp beam on the loom are consumed, the loom device, for example as disclosed in Japanese Patent Application Laid-Open No. 63-99355, detects the warp cut of the empty warp beam on the loom by means of a warp cut detection device, which has passed its warp threads. The loom, together with the heald frame and reed, is carried to the preparation room, and the loom with the above-mentioned structure and the preparation support are transferred onto a table as shown in FIG. Both the left and right bearing portions 40a of the empty warp beam 40 are attached to the mounting recess 15.
After being temporarily placed on the mounting recess 15c along the guide groove 15a. Due to this transfer arrangement, the brake plate 27
is pressed against the flange portion of the empty warp beam 40 by the action of the pressing spring 32, and rotation of the empty warp beam 40 is prevented. By hooking the hook 33 to the warp beam shaft 40b, lifting of the empty warp beam 40 due to the action of the pressing spring 32 is prevented, and the empty warp beam 40
will not come off from the mounting recess 15c.

On the other hand, the warp cut detection device 41 which incorporates a large number of droppers (as shown)
The heald frames 42 are suspended by a pair of left and right hanging bars 25.
3 is mounted and held on the holding frame 24 which is fixed at the standby position shown in FIG. 1 by tightening the fixing screw 39. A cloth W is left on the tip end side of the warp T of the empty warp beam 4°, and a total of 20 pieces of cloth W on the winding reroller 19 are inserted into this cloth W.

If the handle 22 is rotated from this state, the warp threads T1 are pulled and taut. This will cause the sky warp beam 4
The path of the warp thread T1 from 0 to the reed 43 is between the warp thread path and the path on the loom. After the warp threads are tensioned, a tape is attached to the warp T1 row in its width direction, and the attached portion is cut along the tape. Then, in the preparation stage of the machine, the empty warp beam 40 is removed from the stand and a full warp beam 44 is mounted instead as shown in FIG.
The warp threads T2 and the diameter threads T1 of No. 4 are tied one by one using a splicing device. At this time, the tip side of the warp threads T2 is also pasted with tape, and the pasted portions of both warp threads TI and T2 are tied together by an appropriate means. Yarn splicing work is performed by pinching and supporting.

After the yarn splicing is completed, the tape is removed and the adjustment handle 29 is screwed to the position shown in chain lines in FIG. 3 to loosen the pressure of the brake plate 27 against the flange portion of the full warp beam 44. When the handle 22 is rotated, the full warp beam 44 rotates while receiving the braking action of the brake plate 27, and the knot t of the new and old side warps T2 and T1 is inserted into the insertion hole of the dropper of the warp cut detection device 41 and the heald. It passes through the heald insertion hole of the frame 42.

After the knot passes through the heald frame 42, the rotation operation of the handle 22 is temporarily stopped, and the tightening of the fixing screw 39 is loosened. This allows the holding frame 24 to swing back and forth around the support shaft 36 from the standby position shown in FIG. Therefore, the handle 22
If the warp threads are pulled out by rotating the threads, the knots t will enter the threads in multiple units, and if the insertion resistance is large at this time, the knots 4
3 is dragged forward around the support shaft 36. Therefore, by rotating the handle 22 while appropriately swinging the holding frame 24, the entire warp row near the knot can be unraveled. A plurality of knots t aligned substantially in a straight line in the width direction of the warp row pass through a single passage, but the crowded state of the plurality of knots t is broken by warp sorting by swinging of the reed 43. Further, even if the thread end extending from the knot t is entangled with another warp thread, this entanglement is released by passing the liquid back and forth relative to the knot t. Therefore, the passage resistance when the knot t passes through the reed 43 is significantly reduced compared to when the reed 43 is in a stationary state, and warp yarn breakage is reduced.

After the knot t passes through the reed 43 as shown in FIG. 4, the fixing screw 39 is tightened to fix the holding frame 24 in the standby position. Then, by cutting off the knot and removing it, the threading operation is completed, and it can be stored as is until needed.

Note that the period of swinging of the reed 43 is not limited to the period during which the knot t passes through the reed 43, but may be carried out during the rotation operation of the handle 22. It also reduces the passing resistance when pulling through.

The present invention is, of course, not limited to the above-mentioned embodiment, but also includes the embodiment shown in FIG. 5, for example.

In the embodiment shown in FIG. 5, a motor 45 is attached to the upper horizontal bar 14d constituting the support body 14, and a crank disk 46 is operatively connected to the motor 45 via a reduction gear mechanism (as shown). A holding frame e4 is operatively connected to the crank disk 46 via a connecting rod 47.

Therefore, as the crank disk 46 rotates, the holding frame 24 swings about the support shaft 36, and when the motor 45 is not operating, the locking function of the reduction gear mechanism prevents the holding frame 24 from swinging. Note that the connection position of one end of the connecting rod 47 can be adjusted along the elongated hole 46a on the crank disk 46,
By adjusting this connection position, the swing range of the holding frame 24 can be adjusted.

Further, in the present invention, it is also possible to interlock the rotation of the handle of the warp draw-out mechanism with the rotation of the crank disk 46 in the embodiment shown in FIG. 5, or to operate the warp draw-out mechanism side by a motor. .

[Effects of the Invention] As described in detail above, the present invention provides a reed holder that is capable of fixedly holding a reed at a standby position on a support body constituting a stand, and that is capable of holding a reed so as to be able to swing in the front and back directions of the standby position. Since the moving mechanism is installed, it is possible to reduce the passing resistance when the knot passes through the reed by swinging the reed at least while the knot is passing through the reed while pulling out the warp threads, thereby reducing thread breakage. This provides an excellent effect in that the warp thread threading operation can be carried out smoothly while performing the swinging of the reed that leads to suppression.
