Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a weaving device used for mounting and removing a warp beam and a member through which warp threads are passed from the loom to and from the loom.

(Prior art) In the weaving work in which a warp beam is attached to a loom and its warp threads are passed through the component equipment, it is necessary to install a new warp beam before installing a new warp beam in order to reduce the time required for the above-mentioned work, which will lead to improved operating efficiency of the loom. A work procedure is generally adopted in which the warp threads are inserted in advance through a dropper for detecting warp breakage.

The warp cut detection device has a configuration shown in FIG. 7, in which a pair of left and right substrates 101 (only one is shown in the drawing) is connected by a pair of front and rear support tubes 102, 103 to form a support frame. 101 There are multiple contact bars 10 between the upper ends.
4 have been constructed. These contact bars 10
4 is fixed by a connector 105 which is removably fixed on the substrate 101, and each contact bar 104 has a large number of droppers 106 through which warp threads T are inserted, which are vertically movable. The contact bar 104 has a conductor 113a and a conductor 10.
The dropper 106 consists of a resistor 104c sandwiched between the lower part of the resistor 4a and an insulator 104b.
When supported by the warp T, the resistor 10
4c, and when the warp T is cut and the dropper 106 falls, the conductor 10
4a and the resistor 104c, and a warp cut detection signal is issued to stop the machine.

(Problems to be Solved by the Invention) When a warp cut detection device having the above-mentioned configuration is attached to or removed from a loom during weaving work, conventional methods have been disclosed, for example, in Japanese Patent Publication No. 59-44420. A method has been adopted in which the support frame is mounted on the loom and the dropper 106 and contact bar 104 are replaced. However, since the gap between each contact bar 104 cannot be fixed, the droppers 106 or the warp threads T and the dropper 1 cannot be connected to each other during machine work or transportation.
There was a tangle with 06. Such entanglement phenomenon leads to malfunction of warp cut detection and warp cut, leading to a decrease in machine operating efficiency. Moreover, during the rigging work, the complicated work of removing and attaching the contact bar 104 to the board 101 is required, which reduces the efficiency of the rigging work.

Japanese Patent Publication No. 57-53899 discloses a mechanical device that transfers the entire warp cut detection device at once, but this mechanical device also transfers the back crawler lab bracket in one piece. and
The work of removing and installing the back crawler bracket, which essentially does not require transfer, is much more complicated than the work of removing and installing only the warp cut detection device.

In addition, the height position of the warp cut detection device is set by selecting the best warp line depending on the yarn type, fabric type, loom rotation speed, etc., so if the warp cut detection device has a different height position, The problem is that it cannot be addressed.

Structure of the Invention (Means for Solving Problems) Therefore, in the present invention, a latching member that releasably latches and supports the entire warp cut detection device as described above is provided in a height-adjustable manner. A weaving device was constituted by a warp cut detection device transfer means and a warp beam transfer means for attaching a full warp beam to a loom and removing an empty warp beam from the loom.

(Function) That is, the entire warp cut detection device that has passed the warp threads of the warp beam is transported together with the warp beam, and during machine work, the entire warp cut detection device is suspended by the warp cut detection transfer means. It is transferred between the setting device and the loom. Therefore, the contact bar constituting the warp break detection device is fixed, and the numerous droppers through which the warp threads are passed are held in a stable state, and the above-mentioned entanglement phenomenon does not occur. Furthermore, even when changing the mounting height position of the warp cut detection device that is involved in setting the warp line according to the weaving conditions, the warp cut detection device can be moved by adjusting the mounting height position of the hanging member. This increases the degree of freedom in selecting and setting the transfer operation of the hooking member within a range suitable for loading.
