Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Field of Application) The present invention relates to a warp beam and a stand for supporting a warp beam and a member through which warp threads are inserted.

(Prior art) In order to reduce the time required for the above-mentioned work, which will lead to improved operating efficiency of the loom, the process of attaching a warp beam to a loom and passing the warp threads to the weaving device is carried out before installing a new warp beam. Generally, a work procedure is adopted in which the warp threads are passed through the heald frame and the reed in advance. The reed 3 or the dropper box 4 that accommodates the dropper for detecting warp yarn breakage is connected to the warp beam l.
The assembled warp beam 1, heald frame 2, reed 3, and dropper box 4 are placed on the floor or stored under suspension, as shown in the figure. Ru. In other words, by adopting such a work procedure, it is no longer necessary to tie the warp threads on the new warp beam side and the warp threads on the woven fabric side one by one on the warp path from the warp beam to the heddle frame on the loom. Work time can be shortened.

(Problem to be Solved by the Invention) However, in the storage method in which the heald frames 2, reeds 3, etc. with warp threads inserted therein are gathered on the warp beam 1, the bent shape of the warp threads is significantly different from the warp guide shape in a loom. Warp beam 1
, when assembling and separating the heald frame 2, reed 3, etc., it is inevitable that the warp threads become entangled with each other, or that the warp threads are damaged due to friction with each member 2, 3, 4, etc., and when the heald frame 2, reed 3, etc. are assembled and separated, warp thread damage is inevitable. This tends to cause misalignment of each member, and the upper string 5 itself disturbs the warp layer on the warp beam 1, further promoting intertwining of the warp threads. Moreover, the assembled shape of each member that provides the above-mentioned bending and holding shape of the warp threads makes it difficult to automate the mechanical means for attaching the reed 3, heald frame 2, warp beam 1, etc. to the loom. ■It harms the automation orientation of the world.

Structure of the Invention (Means for Solving Problems) Therefore, in the present invention, at least a warp beam, through which the warp threads of the warp beam are inserted, has a positional relationship that can support the warp threads of the warp beam in substantially the same shape as the warp delivery shape of the loom. A support body for removably erecting and supporting the heald frames and reeds, and a braking mechanism for imparting a braking action to the warp beam rotatably supported by the support body constituted a stand for preparing the machinery. .

(Function) That is, the empty warp beam that has been removed from the loom and the warp threading member through which its warp threads are threaded are supported by the support body, and the warp threads are cut between the empty warp beam and the warp threading member, and the warp threads are cut between the empty warp beam and the warp threading member, and the warp threads are cut between the empty warp beam and the warp threading member. The warp threads of the warp beam are connected to the old warp threads on the warp threading member side. Then, if you pull out the warp threads all at once from the full warp beam until the warp knot passes through the reed,
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 the warp threading member into which the warp threads have been threaded are stored in a state that supports the warp threads in the warp delivery shape on the loom. . Therefore, the connection between the warp thread threading work, which is one of the preparation steps, and storage are extremely smooth. When passing the warp threads, the rotation of the warp beam can be controlled by operating the braking mechanism as necessary, and this control allows the warp threads to be pulled out and warp knots to be smoothly performed. Moreover, the support shape of the warp threads in the storage mode is approximately the same as the warp delivery shape on the loom without intertwining of the warp threads, and there is no friction between the warp passing member and the warp threads, which could cause damage to the warp threads. Since the warp threading member that supports the warp threads in substantially the same shape as the warp delivery shape is similar to the mounting state on a loom, it is easy to automate mounting and removal using mechanical means.

(Example) Hereinafter, an example embodying the present invention will be described based on FIGS. 1 to 3.

A guide plate 15 is fixed to the upper surface of the pedestal 14a at the front of the support body 14, which consists of a pair of left-right symmetrical side frames (only one shown) connected by connecting bars 10.11 and 12.13. A guide groove 15a is recessed in the upper surface of the guide groove 15, and mounting recesses 15b are provided at both front and rear ends of the guide groove 15a.

15c is formed. A hook 33 is rotatably attached near the rear end of the guide plate 15, and is restricted by a pin 34 between the solid line position and the chain line position in FIG. A support bracket 16 is fixed to the upper end surface of the pedestal 14a, and a mounting recess 16a is formed in the upper surface of the support bracket 16.

Support brackets 17 (only one is shown) are fixed to the rear surfaces of the upper ends of both left and right branches 14b at the rear of the support body 14, and a shaft 18 is rotatably supported between the brackets 17. 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 take-up roller 19 is fixed to the shaft 18, 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 arranged and fixed to the outside thereof. As a result, the handle 22 can be rotated only in the direction of the arrow in FIG.

゛Both branches 14b near the mounting position of the support bracket 17
A holding frame 24 for the reed device is erected and supported between them, and a pair of left and right hanging bars 25 (only one shown) for hanging the heddle frame is supported directly above the holding frame 24 so that the height position can be adjusted. has been done.

A lever 26 is rotatably supported on the lower horizontal bar 14c constituting the support body 14, and a brake plate 27 is rotatably supported at the tip of the lever 26. Brake plate 2
A brake lie 7 a is fixed to the surface of the brake lie 7 . A guide column 2 is erected at the rear of the horizontal bar 14c corresponding to the rear end of the lever 26, and an adjustment handle 29 is screwed and supported on the guide column 28 so as to be movable up and down. A pair of upper and lower rings 3 are located in the middle of the adjustment handle 29.
0.31 are fixed at appropriate intervals, and the lever
A forked portion at the rear end of 26 extends between rings 30 and 31, and a pressure spring 32 is interposed between the upper ring 3 and the forked portion. Therefore, adjustment handle 2
By rotating 9 in the forward and reverse directions, the adjustment handle 29 is threadedly moved up and down, and the spring action of the pressing spring 32 on the lever 26 is adjusted.

When the warp of the warp beam on the loom is consumed, the loom, as disclosed in Japanese Patent Application No. 61-177416, for example, detects the empty warp beam on the loom by a warp cut detection device, which has passed the warp. 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 left and right bearing portions 35a of the empty warp beam 35 are attached to the mounting recess 1.
After being temporarily placed on the mounting recess 15c along the guide groove 15a. Due to this transfer arrangement, the brake plate 2
7 is pressed against the flange portion of the empty warp beam 35 by the action of the pressing spring 32, and the rotation of the empty warp beam 350 is prevented. By hooking the hook 33 to the warp beam shaft 35b, the floating of the empty warp beam 35 due to the action of the pressing spring 32 is prevented, and the empty warp beam 35 is
5 will not come off from the mounting recess 15c.

On the other hand, the warp cut detection device i3 has a built-in number of droppers.
6 is mounted between the mounting recesses 16a of the left and right support brackets 16, and the plurality of heald frames 37 are hung by a pair of left and right hanging bars 25, and the reed 38 is suspended from the holding frame 24. It is placed and held on top. Warp T of empty warp beam 35
A cloth W is left on the tip side of the cloth W, and a needle 20 on a winding roller 19 is 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 3
The path of the warp threads T1 from No. Cut the pieces along the tape. Then, the preparation receiver removes the empty warp beam 35 from the stand and replaces it with the second one.
As shown in the figure, a full warp beam 39 is mounted, and the warp threads T2 and old warp threads T1 of the full warp beam 39 are tied one by one by a thread splicing device. At this time, the tip side of the warp thread T2 is also pasted with tape, and the pasted portion of the double-sided threads TI and T2 is clamped and supported by appropriate means, and the double-sided threads TI and T2 are tensioned appropriately. This is necessary for yarn splicing work using a yarn splicing device.

It is also necessary to arrange the final portions of the double-sided yarns Tl and T2 at a height suitable for the yarn splicing operation by the yarn splicing device. Therefore, the adjusting handle 29 is screwed in with the final part placed at a position lower than the appropriate yarn splicing height position, and the full warp beam 39 is slowly rotated by rotating the handle 22. The pressing action of the braking plate 27 against the full warp beam 39 is adjusted to the extent that the full warp beam 39 is pressed against the full warp beam 39. As a result, the full warp beam 39 rotates while being subjected to an appropriate braking action, and the final portion is placed at an appropriate height position.

After this arrangement, the adjustment handle 29 is rotated in the opposite direction to strengthen the pressing action of the braking plate 27' against the full warp beam 39, and the full warp beam 39 (with the D-time IJI disabled) Do the splicing.

After the yarn splicing is completed, the portion pasted by the tape is removed, and the adjustment handle 29 is screwed to the chain line position as shown in FIG. 2 to release the braking plate 27 from the full warp beam 39. Then, by rotating the handle 22, as shown in FIG. 3, the new and old side warps T2. The spliced portion of the TI is pulled through the warp cut detection device 36, the heald frame 37, and the reed 38. After that, the threading work is completed by cutting and removing the 20th thread joint part t, and the threading work can be stored as is until needed. Therefore, the connection between the warp threading work, which is one of the preparation steps, and storage are very good. During this threading operation, the warp threads can be prevented from loosening by applying an appropriate braking action to the warp beam by the braking mechanism, and it is possible to prevent the warp threads from becoming entangled with each other.

Furthermore, since the support shape of the receiver for the warp threads T2 on the table is substantially the same as the warp delivery path on the 18-machine, the above-mentioned machine work can be easily transferred and loaded automatically by the device.

Of course, the present invention is not limited to the above embodiments (
For example, it is possible to employ a hydraulic brake or a pneumatic brake controlled by an electromagnetic valve as the braking mechanism, or to configure a braking control mechanism using an electromagnetic clutch.

Effects of the Invention As detailed above, the present invention provides at least a warp beam, a heald frame through which the warp of the beam is inserted, and a heald frame having a positional relationship capable of supporting the warp of the warp beam in substantially the same shape as the warp delivery shape of the loom. The support body that removably supports the reed, and the braking mechanism that applies braking action to the warp beam that is rotatably supported by the support body constitutes a stand for the preparation light of the machine, so that the warp threads can be easily entangled. In addition, it is possible to smoothly carry out the warp thread threading work, which is one of the preparation steps, while also providing a smooth link between the thread splicing work and storage, and the automation of loading and unloading by mechanical means. It has the excellent effect of promoting
