Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Field of Application) The present invention relates to a device for guiding the supply of the warp yarns for the selvage in a shuttleless loom.

(Prior Art) The warp yarns for throwing away, which are supplied from a plurality of yarn supplying bobbins arranged behind the heddle frame on the shuttleless loom, are guided to respective healds of the heddle frame along a predetermined route by a guide stand, The leading end portion of the weft thread that has been wefted is gripped and captured by these plural selvage warps. By this grasping and catching, the posture of the weft inserted is adjusted and the desired woven fabric can be formed.

(Problems to be solved by the invention) As the woven fabric is formed, the warp of the warp beam is consumed and it is necessary to replace it with a new warp beam. In this replacement, a new warp beam warp thread is generally used in advance by passing it through another warp member such as a heddle frame or a reed, and for that reason, in the warp beam replacement work (mechanization work) For example, it is necessary to replace a plurality of heddle frames at the same time by using a mechanism device disclosed in Japanese Patent Application No. 61-177416. However, since the guide stand that guides multiple warp yarns for warps is fixedly installed behind the heddle frame and within the width of the heddle frame, the transfer route of the heddle frame places restrictions on the height of the guide stand. The receiving and horizontal transfer route must be set above the guide stand. Such a route setting causes a conflict with the constraint due to the height of the ceiling of the weaving room, and it is inevitable that the degree of freedom in the route setting for performing a smooth transfer operation is reduced.

Configuration of the Invention (Means for Solving the Problems) Therefore, in the present invention, the thread guide body and the thread guide body of the warp thread for the selvage thread which are supplied from the plurality of thread selvage supply bobbins and are drawn through the heddle of the heddle frame. The guide stand, which is composed of the support pillars, supports the position for guiding the warp yarns for the throwing selvage above the lower end of the heddle frame within the width of the heddle frame and the lower end of the heddle frame transferred during machine work. The warp yarn guide device for the selvage selvage was constructed so that it could be switched to the retracted position below.

(Operation) That is, when the machine base is in operation, the guide stand is arranged at a use position above the lower end of the heald frame. Then, the warp yarn for throwing away is guided along a predetermined supply route by the guide body of the yarn guide stand. On the other hand, the guide stand is arranged at the retracted position below the lower end of the heddle frame during the machine work using the device. Therefore, it is possible to set the transfer path of the heddle frame at a height position that intersects with the use position of the throw-away warp guide device. Therefore, it is possible to set the transfer route of the heddle frame while suppressing the ratio of being restricted by the height of the ceiling of the weaving room, and the degree of freedom of route setting for achieving a smooth transfer operation is increased.

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

As shown in FIG. 1, the warp yarn T sent from the warp beam 3 on the support bracket 2 attached to the rear part of the shuttleless loom 1 passes through the back roller 4 and the warp yarn cutting detection device 5 incorporating a large number of droppers, A plurality of heddle frames 6 suspended and supported between a pair of left and right opening brackets 1a, 1b for forming warp shed and a reed 8 on a sley 7 are passed through the heddle frame 6
A guide stand 9 for guiding the warp yarns T1 for throwing away yarns supplied from a warp bobbin for throwing away yarns (not shown) is erected at the rear in the left and right width of the.

The guide stand 9 is slidable up and down with a lower column 10 fixed to the side frame of the shuttleless loom 1, a connector 11 fixed to the upper end of the lower column 10 with a bolt 21, and a bolt 22. Upper post clamped to connector 11 on
12 and a support shaft 13 is fastened and fixed to the upper end of the upper column 12. An angle-shaped thread guide body 14 is tightened and fixed on the outermost side of the support shaft 13 so that the mounting position can be adjusted, and an elastic piece 15 extends to the opening bracket 1a side and can be elastically displaced up and down inside thereof. It is wound around and fixed. Further, a thread guide piece 16 is laterally tightened and fixed to the inside so that it extends toward the opening bracket 1a side, and a plurality of warp yarns for throwing away
T1 is guided through the thread guide hole 14a of the thread guide body 14, the thread guide hole 15a on the tip side of the elastic piece 15, and the thread guide hole 16a on the tip side of the thread guide piece 16. The warp yarn T1 for throwing away thus guided is further guided through the yarn guide hole 17 in the opening bracket 1a, and is passed through the heddle frame for throwing away formation.

When the warp beam T of the warp beam 3 is consumed, a machine work for mounting a new warp beam on the loom is performed, but the warp cutting detection device 5, the heddle frame 6 and the reed member 8 are the warp beam 3 The shuttleless loom 1 with the warp thread T passed through
Removed from. For example, Japanese Patent Application No. Sho 61
-177416 is used, and the warp beam 3 and the respective passing members 5, 6, 8 are collectively put into the shuttleless loom 1
And a warp beam and its warp threaded warp members are mounted on the loom instead.

A hooking member 18 shown in the drawings is one component of the device for a machine tool, and is used to hook and suspend the heddle frame 6 and the reed 8.
When removing the heald frame 6 from the shuttleless loom 1, first use the bolts 22
Is loosened and the upper support 12 is moved downward from the use position shown by the chain line in FIG. 2 to the retracted position shown by the solid line. In this state,
The hooking member 18 is inserted into the hooking portion (between the upper frame and the upper carrier rod for hooking the heddle) of the plurality of heald frames 6 in the leveling state on the shuttleless loom 1 and then moved upward. As a result, the plurality of heald frames 6 are collectively pulled up from the upper end of the channel-shaped guide body 19 between the opening brackets 1a, and the heald frames 6 can be moved horizontally from this withdrawn position. The pulling-up height position intersects with the upper column 12, the thread guide body 14, the elastic piece 15, and the thread guiding piece 16 of the guide stand 9, but the upper column 12 is moved downward from this pulling-up height position. Therefore, it is possible to set a transfer path in the horizontal direction at this pull-out height position. As a result, the range in which the transfer path of the reed 8 is set is expanded so that the machine setting device does not interfere with the ceiling of the weaving room, and the degree of freedom in setting the transfer path for achieving a smooth transfer operation is increased.

Even when a new warp beam and a threading member are transferred from the tacking device side to the shuttleless loom 1 side, the upper reed 12 is moved downward from the use position so that the new reed does not interfere with the guide stand 9. Can be reprinted along.

Of course, the present invention is not limited to the above-described embodiment. For example, an integrated guide stand may be tilted and retracted from its use position to the side, or the piston rod of the fluid pressure cylinder may be replaced by the upper support column in the above-mentioned embodiment. It can be used instead of 12. In this case, the warp detector is installed on the guide path of the warp yarn for throwing away, and the heddle frame transfer preparation is completed based on the detection signal of no warp yarn for throwing away when the guide stand is moved from the use position to the retracted position. It is also possible to configure the display or mechanism device to be in the transfer operation executable state.

Effect of the Invention As described in detail above, the present invention, when performing a machine-setting operation using the machine-moving device, includes a guide stand that includes a thread guide body for a warp thread for a selvedge and a column that supports the thread guide body. Since the switching position is set from the use position where the warp yarns are guided along the predetermined supply route to the retracted position that does not intersect with the heddle frame transfer route, the ratio restricted by the height of the ceiling of the weaving room is suppressed. The transfer path of the heddle frame can be set, and the excellent effect that the degree of freedom in path setting for achieving a smooth transfer operation can be increased is achieved.
