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 threads to the weaving machine side, before installing a new warp beam, consider the time reduction of the work that leads to improvement of 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, it is necessary to collectively mount the heald frame by means of a machine setting device as disclosed in JP-A-62-223344.
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, for example, as described in JP-A-63-243355, a guided member is provided at the upper left and right center of the heddle frame. A means for preventing the vibration by providing the guided member together between the pair of guide members on the loom body side is effective.

[Problems to be Solved by the Invention] However, particularly in a machine work operation in which the heald frames are collectively replaced by a machine device, the rear guide member becomes an obstacle when the heald frames are transferred. 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 to minimize the gap setting, the front guide member also hinders the batch mounting of the heald frames 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, the front guide member is supported so as to be switchable between the guide position and the retracted position of the heald frame, and the rear guide member is provided on the front guide member. Provided with a position regulation mechanism that supports the guide position and the retracted position so as to be able to rotate and reverse over the vertical movement region of the heddle frame and keeps the switching arrangement of the front and rear guide members from the retracted position side to the guide position side on the guide position. It was

[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 device position on the loom and the heald frame can be collectively mounted at the mounting position without any trouble. When the front and rear guide members are switched and moved from the retracted position to the guide position after the installation of the heddle frame, this switching movement is kept on the guide position by the position regulation mechanism, and the front guide member is held at the predetermined guide position. It

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

Hanging ropes 1 and 2 are connected and suspended on 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 hanging ropes 1 and 2. The attachment bodies 3 and 4 are suspended and suspended by means of the coupling coupling members 5 and 6. Pull-down ropes 7 and 8 operatively connected to a cam mechanism (not shown) are connected to the lower ends of the movable mounts 3 and 4 via hook connecting members 9 and 10, respectively, so that the rotation of the cam is fixed to the movable mounts 3 and 4. Converted to 4 up and down movements, and this up and down movement 1
Guided by 1,12.

The heddle frame 13 includes left and right side stays 13a, 13b, upper and lower frames 13c, 13d connecting the both side stays 13a, 13b, and upper and lower carrier rods 13e, 13f for suspending a heddle, which are installed between both side stays 13a, 13b. Each of the heddle frames 13 has channel-shaped guided members 14A and 14B sandwiched and fixed to the left and right central portions of the upper and lower frames 13c and 13d. As for the heddle frame 13, the left and right side stays 13a and 13b are attached to the mounting grooves 3 of the movable mounting members 3 and 4.
It is erected and supported between the movable attachment bodies 3 and 4 by being fitted in the a and 4a and fixed by appropriate means. As a result, the heddle frame 13 moves up and down together with the movable mounts 3 and 4, and the warp shed is formed. Upper guided member 14A and lower guided member 14B
Are adjacent to each other with a slight gap therebetween, and the lower guided member 14B is collectively guided by front and rear guides below the heddle frame as disclosed in the drawing of JP-A-63-243355.

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 provided at the center of the support pipe 15.
Is fastened with screws 17 so that the mounting position can be changed. On the upper part of the support bracket 16, a support shaft 18 is provided with a support pipe 15.
A screw 19 is tightened and fixed so that the mounting position can be changed in a direction orthogonal to the direction (front-back direction of the loom), and a front guide member 20 is drooped to the rear end of the support shaft 18.

A position restriction ring 33 is fitted to the front end of the support shaft 18, and is tightened and fixed by a screw 34. The support shaft 18 and the front guide member 20 are restricted from sliding rearward by the position restriction ring 33. It

A shaft pin 21 is provided so as to penetrate in the left-right direction at the upper end of the base end of the front guide member 20, and the support blocks 2 are provided at both ends of the shaft pin 21.
2,23 are tightened and fixed by screws 24,25. As shown in FIG. 2, on the lower half side of the peripheral surface of the shaft pin 21 corresponding to the screw 24, a position regulating groove 21a is provided in a semi-arc shape, and the screw 25
A similar position regulating groove (not shown) is also formed on the side. The tip of the screw 24 enters the position regulating groove 21a and is tightened and abutted on the bottom surface of the position regulating groove 21a.

Support rods 26 and 27 are tightened and fixed to the support blocks 22 and 23 by screws 28 and 29 so that the mounting position can be adjusted forward and backward.
A rear guide member 30 is suspended between the rear ends of the support rods 26, 27. In the state shown in FIGS. 1 and 2, the support rod 26,
27 is set at a position higher than the vertical movement region of the heddle frame 13, and both 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. When the tip of the screw 24 is inserted into the position regulating groove 21a, the side surface of the tip of the screw 24 is located at one end 21b of the position regulating groove 21a.
The rear side guide member 30 is restricted from rotating leftward about the shaft pin 21 by contacting the rear side guide member 30, and the distance between the rear side guide member 30 and the guided member 14A in the last row is as shown in FIG. The contact relationship between the one end 21b of the position regulating groove 21a (that is, the position regulating end face) and the screw 24 is set so that the predetermined interval is established.

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 device for arranging a heddle frame transfer means provided with a pair of hooking members 31 capable of suspending the heddle frame collectively is used. When performing the machine work with this machine device, first level the heald frame 13 and loosen the screws 24 and 25 to release the shaft pin 2
The rear side guide member 30 is rotated around the position 1 from the guide position to the front. In this case, the screws 24 and 25 are loosened so that their tips do not separate from the position regulating groove 21a.

As shown in FIG. 3, by loosening the screws 24 and 25, the rear guide member 30 is rotated and inverted to the front side above the vertical movement region of the heald frame 13, so that the support rod 26 is positioned on the support bracket 16. The rear guide member 30 is held in the retracted position shown in FIG. Then, when the screw 19 is loosened and the spindle 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 and 30 from the guide position to the retracted position, the locking device is activated by operating the device.
31 enters between the upper carrier rod 13e and the upper frame 13c of the heald frame 13 shown by the solid line position in FIG. 4 along a predetermined transfer path. When the hooking member 31 moves upward, the heald frame 13 is collectively pulled out upward from the movable mounting bodies 3 and 4, 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, and the heddle frame 13 can be collectively pulled out without any trouble. As shown in FIG. 5, the new heald frame 13 which is latched and supported collectively by the latch member 31 is inserted into the movable mounting bodies 3 and 4 along a route opposite to the pullout 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 guide member 20 is reduced as much as possible in order to enhance the guide function of the front guide member 20, particularly the front and rear vibrations of the heald frame 13 during high-speed operation are also well suppressed. However, this reduction in the distance hinders the mounting of the heddle frame 13 at once. Therefore, the rear guide member 30
It is better not only to move the heddle to the retracted position, but also to keep the front guide member 20 away from the transfer path of the heddle frame 13, so that the heddle frame guide device of the present invention maintains the high guiding function during high-speed operation while maintaining the heddle frame. Also ensure good workability of 13 batch transfer.

After collectively mounting the heald frame 13 on the loom side, sliding the support shaft 18 to the rear causes the position regulating ring 33 to contact the support bracket 16, thereby switching the front guide member 20 from the retracted position side to the guide position side. Can be stopped. Therefore, by appropriately setting the tightening position of the position regulating ring 33, the front guide member 20 can be easily positioned at the optimum gap position with the guided member 14A in the front row. As a result, the guiding action of the front guide member 20 is favorably performed.

After the front guide member 20 is switched to the guide position and the screw 19 is tightened, and the rear guide member 30 is rotated from the retracted position to the guide position side, the tip end of the screw 24 comes into contact with the position regulating end surface 21b. , Rear guide member from the retracted position side to the guide position side
The switching arrangement of 30 is stopped. Therefore, the rear guide member 30
Is also easily switched to a position where the distance between the guided members 14A in the last row is optimally maintained, and the front and rear guide members 20, 3 are arranged.
The 0 guides the vertical movement of the heddle frame 13 well.

Of course, the present invention is not limited to the above-mentioned embodiment, and for example, a screw portion is provided at the front end of the support shaft 18, and a pair of nuts are screwed and fixed to this screw portion, and a position regulating mechanism for the front guide member is provided. Or support block 22,2
It is also possible to provide an embodiment in which a stopper for restricting the position of 3 at the rotation position corresponding to the guide position of the rear guide member is provided.

[Advantages of the Invention] As described in detail above, according to the present invention, the front guide member is supported so as to be switchable between the guide position and the retracted position of the heald frame, and the front guide member is provided with the rear guide member. Provided with a position regulation mechanism that supports the guide position and the retracted position so as to be able to rotate and reverse over the vertical movement region of the heddle frame and keeps the switching arrangement of the front and rear guide members from the retracted position side to the guide position side on the guide position. Therefore, while maintaining a high guide function, batch transfer of heddle frames at the time of machine work can be facilitated, and switching arrangement of the front and rear guide members to the guide position can be easily and accurately performed, and the loom can be operated at high speed. It has an excellent effect that it is possible to facilitate the work of the mechanism while sufficiently responding to.
