Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a heddle frame guide device in a loom.

[Prior Art] When mounting a warp beam on a loom and passing the warp thread to the weaving machine side, before installing a new warp beam in consideration of shortening the time of the work leading to improvement in the operating efficiency of the loom. A work procedure in which the warp thread is inserted through a plurality of heddle frames in advance is generally adopted. Therefore, in order to mount the heddle frame on the loom, a collective device using a machine setting device as disclosed in, for example, JP-A-62-223344 is required. The heddle frame, which is made thin to cope with the increase in the speed of the loom, has a lateral width corresponding to the width of the loom. Therefore, when the loom is operated, the entire heald frame is likely to vibrate greatly in the front-back direction at the left and right central portions. Since such vibration causes not only damage to the heddle frame itself but also damage to the warp, a guided member is provided at the upper left and right center of the heddle frame, and the guided member is provided between the pair of guide members on the loom body side. It is effective to introduce all of them together to prevent vibration.

[Problems to be Solved by the Invention] However, particularly in a machine work for collectively replacing the heddle frames by the machine tool, the rear guide member hinders the transfer of the heddle frames. In addition, the guide relationship between the guided member of the heddle frame, which moves up and down at high speed during high-speed loom operation, and the guide member on the main body side of the loom is greatly influenced by the gap setting between the two, and this gap setting must be minimized appropriately. Required. Therefore, if the gap between the pair of guide members is narrowed in order to minimize the gap setting, the front guide member also interferes with the heddle frame collective device by the machine tool.

It is an object of the present invention to provide a heddle frame guide device which does not hinder such a mechanism work.

[Means for Solving the Problem] Therefore, in the present invention, a guide member is supported on the front side so as to be switchable between a guide position and a retracted position of a heald frame, and a rear guide member is attached to the front guide member. The frame was supported so as to be rotatable and reversible between the vertical position and the guide position and the retracted position.

[Operation] When the heddle frame is transferred, first, the rear guide member is turned upside down to move from the guide position to the retracted position.
Then, by moving the front guide member from the guide position to the retracted position, both the front and rear guide members are separated from the transfer path of the heddle frame. As a result, the heddle frame can be collectively pulled out from the mounting position on the loom and the heald frame can be collectively mounted at the mounting position without any trouble.

Embodiment An embodiment embodying the present invention will be described below with reference to the drawings.

Suspended ropes 1 and 2 are connected and suspended by jack levers (not shown) supported by spring force on both left and right side frames of the loom, and channel-like movable ropes are provided at the lower ends of the suspended ropes 1 and 2. The attachment bodies 3 and 4 are hung and suspended via the latch connecting members 5 and 6. A pull-down rope 7, which is operatively connected to a cam mechanism (not shown), at the lower ends of the movable mounts 3 and 4.
8 is connected via latch connecting members 9 and 10, the rotation of the cam is converted into vertical movement of the movable mounting bodies 3 and 4, and this vertical movement is guided by the left and right guide bodies 11 and 12.

The heddle frame 13 is an upper and lower frame 1 that connects the left and right side stays 13a and 13b and the both side stays 13a and 13b.
3c, 13d, and upper and lower carrier rods 13e, 13f for hooking the heddle between the side stays 13a, 13b.
Channel-shaped guided members 14A and 14B are fixedly attached to the left and right central portions of c and 13d. As for the heddle frame 13, the left and right side stays 13a and 13b are attached to the movable mounts 3 and 4.
By being fitted in the mounting grooves 3a, 4a of and fixed by an appropriate means, it is erected and supported between the movable mounting bodies 3, 4. As a result, the heddle frame 13 moves up and down together with the movable mounting members 3 and 4,
The warp opening is formed.

A support pipe 15 is installed between both side frames above the front side of the mounting position of the heddle frame 13 defined by the guide bodies 11 and 12, and a support bracket 16 is attached to the center of the support pipe 15 with a screw 17. It is fixed so that the position can be changed. On the upper part of the support bracket 16, the support shaft 1
8 is a direction orthogonal to the support pipe 15 (front-back direction of the loom)
It is fastened by screws 19 so that the mounting position can be changed, and a front guide member 20 is drooped to the rear end of the support shaft 18.

A shaft pin 21 is provided in the upper part of the base end of the front guide member 20 so as to penetrate in the left-right direction, and support blocks 22 and 23 are fixed to both ends of the shaft pin 21 by screws 24 and 25. Each of the support blocks 22 and 23 has a support rod 26,
27 is tightened and fixed by screws 28 and 29 so that the mounting position can be adjusted forward and backward, and a rear guide member 30 is suspended between the rear end portions of both support rods 26 and 27. In the state shown in FIGS. 1 and 2, the support rods 26 and 27 are the heald frame 13
Is set above the vertical movement region of the guide member 20, and both the front and rear guide members 20, 30 guide the guided member 14A, which moves up and down at each guide position, from the front and rear.

Now, when replacing the heddle frame with the replacement of the warp beam, insert the warp beam transfer means for mounting the full warp beam on the loom and removing the empty warp beam from the loom and the warp of the warp beam. A machine tool including a heddle frame transfer means including a pair of hook members 31 capable of suspending the heddle frame collectively is used. When performing a machine work with this machine device, first, the heald frame 1
Leveling 3 is performed, the screws 24 and 25 are loosened, and the rear guide member 30 is rotated around the shaft pin 21 from the guide position to the front. As a result, the rear guide member 30 is pivotally reversed to the front side above the vertical movement region of the heald frame 13 as shown in FIG. 3, and the support rod 26 comes into contact with the position restricting portion 16a on the support bracket 16. Rear guide member 3
0 is held in the retracted position in FIG. Then screw 19
And the support shaft 18 is pulled out to the front side, the front guide member 20 moves together with the rear guide member 30 from the guide position to the retracted position as shown in FIG.

After moving both the front and rear guide members 20, 30 from the guide position to the retracted position, the hooking member 31 is operated along with a predetermined transfer path by operating the mechanical device, so that the heald frame 13 shown by the solid line position in FIG. Between the upper carrier rod 13e and the upper frame 13c. Then, the heddle frame 13 is collectively pulled out upward from the movable mounting bodies 3 and 4 by the upward movement of the hooking member 31, but both the front and rear guide members 20 and 30 are separated from the transfer route of the heald frame 13. Since the heald frame 13 is moved to the retracted position, the heddle frame 13 and the front and rear guide members 20, 30 are not buffered at all.
Batch withdrawal of 3 will be performed without any problems. As shown in FIG. 5, the new heald frame 13 which is latched and supported collectively by the latching member 31 is inserted into the movable mounting bodies 3 and 4 along a route opposite to the pulling out route of the heald frame 13. At this time, a new reed 32 is hooked on the tip of the hooking member 31, but the reed 32 does not come into contact with the front guide member 20 in the retracted position.

When the space between the front heald frame 13 and the front heald frame 20 is reduced as much as possible in order to enhance the guide function of the front guide member 20, the front and rear vibrations of the heald frame 13 are also well suppressed especially at high speed operation. However, this reduction of the spacing reduces the heald frame 13
It becomes a hindrance when mounting all at once. Therefore, it is better not only to move the rear side guide member 30 to the retracted position but also to separate the front side guide member 20 from the transfer path of the heald frame 13, so that the heald frame guide device of the present invention is a high guide at high speed operation. While maintaining the function, the workability of transferring the heddle frame 13 at one time is also ensured.

[Advantages of the Invention] As described in detail above, the present invention supports the front guide member so as to be switchable between the guide position and the retracted position of the heald frame, and the front guide member has the rear guide member. Since it is supported so that it can be rotated and inverted between the guide position and the retracted position beyond the vertical movement area of the frame, it is possible to smoothly transfer the heddle frames at the same time during machine work while maintaining a high guide function, and high speed of the loom. It has an excellent effect that it is possible to smoothly carry out the machine work while sufficiently supporting the operation.
