Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a looming device used when a warp beam and a member through which a warp is passed are attached to and removed from a loom. . (Prior Art) In the work of attaching a warp beam to a loom and passing the warp to the weaving device side (mechanical work), a new warp beam is taken into consideration in consideration of the shortening of the work leading to an improvement in the operating efficiency of the loom. An operation procedure in which the warp is inserted in advance through a dropper for detecting warp cut before mounting is generally adopted.
By adopting such a work procedure, a new warp beam-side warp and a woven cloth-side warp are placed on the warp path from the warp beam on the loom to the warp cut detecting device.
There is no need to bind the books one by one, and the time required for the mechanical work can be reduced. As the warp cut detecting device, there is a configuration shown in FIG.
A pair of left and right substrates 101 (only one is shown in the drawing) are connected by a pair of front and rear support tubes 102 and 103 to form a support frame, and a plurality of contact bars 104 are provided between the upper ends of both substrates 101. These contact bars 1
04 is a connector 105 detachably fixed on the substrate 101
A plurality of droppers 106 into which the warp threads T are inserted are arranged in each contact bar 104 so as to be vertically movable. The contact bar 104 includes a conductor 104a and a resistor 10 that is tightly attached to the lower portion of the conductor 104a via an insulator 104b.
4c, the dropper 106 is electrically connected only to the resistor 104c when supported by the warp T, and when the warp T is cut and the dropper 106 falls, both the conductor 104a and the resistor 104c And the machine stand is stopped by issuing a warp cut detection signal. (Problems to be Solved by the Invention) When the warp cut detection device having the above-mentioned configuration is attached to or removed from the loom along with the looming work, conventionally, the support frame is mounted on the loom, A method of replacing the contact bar 104 with the dropper 106 has been adopted. However, since the interval between the contact bars 104 cannot be fixed, the entanglement between the droppers 104 or between the warp T and the dropper 106 occurs during the work in progress or during transportation. That is, since the dropper 106 can move up and down with respect to the contact bar 104, a entanglement phenomenon occurs such that the upper end of the dropper 106 moved down due to the relaxation of the warp T is caught on an adjacent dropper or warp,
When the warp T is stretched on the loom, the dropper 106
Will pass through the next dropper or warp. Such a entanglement phenomenon causes a malfunction such as a warp cut detection and a warp cut, which leads to a decrease in machine operating efficiency. In addition, the complicated work of removing the contact bar 104 from the substrate 101 and the device is required at the time of the mechanical work, which reduces the efficiency of the mechanical work. Configuration of the Invention (Means for Solving the Problems) Therefore, in the present invention, a number of droppers for inserting the warp of the warp beam, a contact bar for supporting the dropper dropped when the warp is cut, and a support for supporting the contact bar A warp-cut detecting device transfer means having a swinging lever which can swing between an engagement position for suspending and supporting the warp-cut detecting device composed of a frame and a release position of the warp-cut detecting device; A warp beam transfer means for mounting a full warp beam and removing an empty warp beam from the loom constituted a mechanism device. (Operation) That is, the entire warp cut detection device that has been passed through the warp of the warp beam is transported together with the warp beam, and the entire warp cut detection device is suspended by the warp cut detection device transfer means during the mechanical work. It is transferred between the machine and the loom. Therefore, the contact bar constituting the warp cut detecting device is fixed, and a large number of droppers through which the warp has passed are maintained in a stable state, and the above-described entanglement phenomenon does not occur. Further, in the present invention, by swinging the latching lever of the transfer means, the warp cut detection device can be easily switched from the engaged position for suspending and supporting to the release position, and the transfer operation of the warp cut detection device is facilitated.

Now, the operation of the mechanism device of the present embodiment in the case where the mechanism work is required will be described below. After the warp beam on the loom 3 and the warp cut detecting device through which the warp has passed, the heald frame and the reed, the reed, are removed, the full warp beam 92, the warp cut detecting device 64,
The heaving frame 82 and the reed 83 are mounted in the state shown in FIG. 1 and the mocking device, which has been waiting in the mocking preparation room, is moved along the groove rail 4 to the mocking work position behind the loom 3.
As shown in FIG. 3, the hook levers 56, 57 are restricted to a rotational position in which the position restricting projections 56a are fitted in the position restricting grooves 54a. In this state, the suspension of the warp cut detecting device 64 is suspended. Band 7
4,75 are hung and suspended by the latch levers 56,57. Hydraulic cylinders 11 and 12 are actuated in the mechanical working position, and both movable rails 9 and 10 are installed between the transport vehicle 2 and the side frame 3a of the loom 3 with the front wheels 15 mounted thereon. Subsequently, the hydraulic motors 24 and 25 are rotated forward, and the auxiliary platform 13 is moved from the standby position on the carrier 2 to the fixed rails 7 and 8 and the movable rails 9 and 10.
Is moved to the mechanism position shown in FIG.
The hydraulic cylinders 90 and 91 are actuated in the process of moving and arranging the auxiliary table 13, and the full-warp beam
92 is temporarily placed on the temporary placement position 89b. Subsequently, the reverse rotation of the hydraulic motors 24, 25 and the operation of the hydraulic cylinders 90, 91 cause the support grooves 87a of the transfer levers 87, 88 to engage with the shaft 92a of the full warp beam 92 in place of the support grooves 87b. With hydraulic motor 2
4, 25 is rotated forward and full warp beam 92 is mounted at position 89
placed on a. Subsequently, while the hydraulic cylinders 39 and 40 are operated,
The hydraulic cylinders 42 and 43 are operated, and the warp cut detecting device 64 is arranged at the mounting position on the loom 3 as shown in FIG. 4, and the heald frame 82 is arranged above the mounting position. In this state, the hydraulic cylinder 81 is operated, whereby the heald frame 82 and the reed 83 released from the holding arms 79 and 80 are manually mounted as shown in FIG. Then the manual knob 5
8,59 is rotated outwardly against the pressing springs 62,63,
The position regulating protrusions 56a of the locking levers 56, 57 shift from the position regulating grooves 54a to the position regulating grooves 54b. Thereby, as shown in FIG. 5, the latch levers 56, 57 are pivotally arranged from the chain line position to the solid line position, and are regulated and held at that position. Accordingly, the warp T of the full warp beam 92 is guided to the warp cut detecting device 64 via the back roller 93, and the warp T of the full warp beam 92 passes through the warp path on the loom 3 to the reed 83. Loom 3
Of the warp cut detection device 64 to the side frame 3a
This is performed by tightening and fixing the supporting protrusion 65a to During this mechanical work, the warp cut detecting device 64 is transferred in a state where the plurality of contact bars 69 passed through the many droppers 72 are fixed and held at predetermined intervals, so that the warp T is loosened and tensioned. The dropper 72 is also held stably,
Entanglement between the 72 and between the dropper 72 and the warp T is avoided. Therefore, a situation such as a warp cut detection malfunction and a warp cut due to the occurrence of such a entanglement phenomenon is avoided, and a decrease in machine operating efficiency is prevented. Further, in order to release the warp cut detecting device 64 from the hook levers 56, 57, the turning operation of the manual knobs 58, 59 is sufficient, and the transfer operation of the warp cut detecting device 64 is extremely easy. After the transfer of the threading members 64, 82, 83 and the full warp beam 92 is completed, the operation of the hydraulic cylinders 42, 43, 39, 40 causes the locking levers 55, 56 and the support hooks 77, 78 as shown in FIG. Returns to the standby position, and the auxiliary platform 13 returns to the standby position on the transport trolley 2 by the reverse rotation of the hydraulic motors 24 and 25. Thereafter, the movable rails 9 and 10 return to the standby position on the transport trolley 2 by the operation of the hydraulic cylinders 11 and 12, and the towing device moves to the in-and-out device preparation room by the towing of the automatic guided vehicle 1. The present invention is, of course, not limited to the above embodiment.For example, the latch levers 56, 57 in the above embodiment are rotationally biased inward by a torsion spring, and the latch levers 56, 57 are rotated by the rotational bias. A configuration in which the bent portion of the tip 57 is hooked on the suspension bands 73, 74 is also possible. In this case, when the warp cut detection device 64 is not suspended, the hook levers 56, 57 are provided.
Is automatically rotated to the release position, which is convenient for the transfer operation of the warp cut detection device. Also, as shown in FIG. 7, pipes 94a and 95a are used as intermediate portions of the suspension bands 94 and 95 that engage with the latch levers 56 and 57, and tips of the latch levers 56 and 57 are adjusted to the pipe shape. Is also possible. This facilitates bending of the hook levers 56 and 57, and the transport and transfer of the warp cut detection device 64 becomes more stable. Further, if the support pins 52, 53 are aligned with the pipes 94a, 95a, the urging force on the hook levers 56, 57 when the warp cut detection device 64 is suspended becomes extremely small, and the hook levers 56, 57 There is no danger of accidentally turning.
This can be similarly applied to the case of the first embodiment. Further, in the present invention, it is also possible to adopt a configuration in which a hook lever is fitted into the opening of the support pipes 67 and 68 in the above embodiment to suspend and support the entire warp cut detection device. The suspension band in each of the above embodiments can be omitted. Alternatively, the substrates 65, 66 in each of the above embodiments
A configuration is also possible in which a screw member screwed to the loom side frame is irremovably attached to the support protrusion 65a on the outer side surface, and the screw member is rotatably suspended and supported. Further, the warp in which the hook lever in the above embodiment is rotated by an appropriate driving means, or a lead wire electrically connected to the dropped dropper is disposed immediately below a contact bar made of a resistor. The present invention is applicable to a looming device in a loom provided with a cut detection device. Effects of the Invention As described in detail above, according to the device of the present invention, it is possible to suppress the entanglement phenomena such as the entanglement between droppers or the entanglement between the dropper and the warp even in the transfer operation, thereby increasing the machine operating efficiency. In addition, the transfer operation of the warp cut detecting device can be easily performed by a simple operation of swinging the latch lever between the engagement position and the release position.
