Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of moving forward and backward and up and down a hanging mechanism capable of hanging a plurality of heddle frames, through which warp threads of a warp beam are inserted, collectively. And a warp beam transfer means for mounting the full warp beam on the loom and removing the empty warp beam from the 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.

An example of a device for carrying and transferring a warp beam and a heddle frame having a warp thread inserted therein is disclosed in JP-A-63-59451 or JP-A-63-99355. In each of these devices, an arm supported by a pair of left and right columns so as to be capable of expanding and contracting in the horizontal direction and a hooking member connected to the tip of the arm constitute a hooking mechanism. It is designed to be hung in a lump.

[Problems to be Solved by the Invention] However, it is difficult to accurately arrange the heddle frame vertically above the guide groove of the guide frame for guiding the opening movement of the heddle frame on the loom, and the forward movement of the hooking member is difficult. Due to this, the heddle frame arranged above the guide frame is likely to shift back and forth from the position vertically above the guide groove. Therefore, it is necessary to move the latch member back and forth again to align the position, but such a fine adjustment operation is very troublesome. Alternatively, the operator can directly align the heddle frame with respect to the hook member by moving the heddle frame back and forth, but the heddle frame also has a considerable weight and the heddle frame must be displaced one by one. This shifting operation is very complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a weaving device capable of easily mounting a heald frame on a loom.

[Means for Solving the Problems] Therefore, in the present invention, a latching member that directly latches and supports a plurality of heald frames, and this latching member can be moved forward and backward relative to the heald frame transfer means. The latching mechanism is composed of a support member that supports the.

[Operation] The heald frame suspended and suspended by the retaining member is arranged above the mounting position on the loom side by the forward movement of the entire retaining mechanism. Even if the heddle frame is not arranged vertically above the guide groove that guides the opening movement due to this forward disposition, the heddle frame can be moved by adjusting the hook member forward and backward with respect to the heddle frame transfer means. They are collectively moved in parallel at a predetermined position.

The aforementioned hydraulic cylinders 10, 18, 38 and hydraulic motors 12, 24,
Reference numeral 39 is adapted to be controlled by a transfer program preset in the transfer control device 3 and a push button (not shown) operation on the transfer control device 3, and as shown in FIG. The transfer operation of the machine-moving device, which is moved along the lead wire to the machine-working position behind the loom 4, is carried out. The full warp beam 40 on the transfer lever 36, the warp cutting detection device 41 through which the warp thread T is passed, the plurality of heald frames 42 on the hooking link 29, and the pair of left and right holders 45 make the front heald frame 42. The reed 43 supported by being hooked is transferred from the machine setting device side to the loom side by the transfer operation.

The hooking link 29 is passed between the upper frame 42a of the heddle frame 42 and the receiving side carrier rod 42b to suspend the heddle frame 42 in a lump. In addition, the guided member is located above and below the center of each heald 42.
42c, 42d are fixed, the lower guided member 42d is collectively guided by the front and rear guides on the loom side disclosed in JP-A-63-243355, and the upper guided member 42c is also different. Guided by the front and back guides. A plurality of heddle frames 42 are hung and supported by hanging links 29 in a state where upper and lower guided members 42c and 42d are in close contact with each other, and the heald frames 42 in this close contact state are separated from each other by the loom 4 side. Guide groove for mounting frame 44
It almost coincides with the interval of 44a.

The transfer operation described above is performed under the grounding of the auxiliary wheel 9a,
By the proper combination of the back-and-forth movement of the auxiliary base 6, the vertical movement of the straight parallel 6-node link mechanism, and the straight parallel movement of the 6-node link mechanism, the movement operation paths of the transfer lever 36, the latch member 25, and the latch link 29 are It is set.

The heald frame 42 on the hooking link 29 is a straight parallel 6-node link mechanism.
The straight parallel movement of 19 causes the forward movement from the solid line position in FIG. 2 to the chain line position, and is arranged above the mounting frame 44 on the loom 4 side. Each heddle frame 42 is moved downward from the position indicated by the chain line in FIG.
It is installed by inserting it into 44a. In order to insert the heddle frame 42 into the guide groove 44a, the heddle frame 42 needs to be arranged vertically above the guide groove 44a, but as shown in FIG.
It may be shifted back and forth from the position vertically above 44a.
Therefore, the downward movement of the straight parallel 6-joint link mechanism 19 is temporarily stopped so that the lower end of the heald frame 42 stops immediately above the mounting body 44, and the entire heald frame 42 is moved back and forth to form a parallel 4-joint link mechanism. The latching link 29 is moved back and forth in parallel. In this case, since the heald frame 42 is mounted on the rubber slip stopper, the heald frame 42 does not slip on the hooking link 29. By this parallel movement, the respective heald frames 42 are collectively translated in the front-rear direction without tilting, and the respective heald frames 42 are collectively arranged immediately above the guide grooves 44a of the mounting frames 44 as shown in FIG. If the straight-travel parallel 6-bar link mechanism 19 is moved downward from this state, each heald frame
42 is easily and collectively inserted into the guide groove 44a of the mounting frame 44.

The heald frames 42 as a whole are quite heavy, but the parallel four-bar linkage mechanisms 27, 28, 29 allow the plural heald frames 42 to be moved in parallel at the same time for easy mounting. The positioning operation of each heddle frame 42 with respect to the guide groove 44a of the frame 44 is extremely easy. Also, left and right parallel four-bar linkage
The configuration in which 27, 28, and 29 can be operated separately is advantageous when the parallelism of the heald frame 42 with respect to the left and right mounting frames 44 is deviated.
Further, even if the parallel four-link mechanism 27,28,29 collides with a part on the loom 4 when the straight parallel six-joint link mechanism is expanded or contracted, the parallel four-joint link mechanism 27,28,29 is tilted to cause the loom to move. There is also an advantage that damage to the parts on the four side can be avoided.

After the installation of the heddle frame 42 to the mounting frame 44 is completed,
The holder 45 is removed from the heddle frame 42 and the reed 43 is mounted at a predetermined device position. Then, as shown in FIG. 6, the hook link 29 is removed from the support link 27, and the straight parallel 6-joint link mechanism 19 is moved up and down to complete the transfer of the heddle frame 42 to the loom 4.

When the heddle frame 42 is transferred from the loom 4 side to the machine setting device side, a hooking link 29 is inserted between the upper frame 42a and the upper carrier rod 42b of the heddle frame 42 from the state shown in FIG. The hooking link 29 may be hooked on the support link 27.

The present invention is, of course, not limited to the above-mentioned embodiment, and the lower end of the support link 27 may be connected by a connecting bar 46 as shown in FIG. 7, for example. The parallel movement of the joint link mechanism is performed integrally,
This is advantageous when the parallelism of the heddle frame 42 with respect to the left and right mounting frames 44 is sufficiently achieved.

In the embodiment shown in FIG. 8, a locking cylinder 47 is slidably fitted to the horizontal end portions of the left and right suspension arms 26, and a connecting rod 48 is installed between the left and right locking cylinders 47. Tensile springs 49 and 50 as support members are provided in front of and behind the retaining cylinder 47. Rubber stoppers 51 are provided on the upper surface of the retaining cylinder 47.
The heald frame is hooked and supported on the slip stopper 51. Therefore, the heddle frame moves back and forth in parallel with the latching cylinder 47, and the same effect as that of the above-described embodiment is obtained. Also, the front and rear tension springs 49, 50 keep the latching cylinder 47 in a fixed position on the suspension arm 26 at all times, so that the latching cylinder 47 moves forward and backward when the straight parallel 6-joint link mechanism is extended. Be constant. Therefore, the hooking position of the heddle frame on the suspension arm 26 can be kept substantially constant, and transfer of the heddle frame between the loom and the machine setting device can be facilitated.

Further, in the present invention, a plurality of grooves are provided on the upper surface of the locking link or the locking cylinder instead of the slip stopper of each of the above-mentioned embodiments,
A heald frame may be fitted in and supported in each groove.

[Effects of the Invention] As described in detail above, according to the present invention, a hooking mechanism that directly hooks and supports a plurality of heald frames and a support member that supports the hooking member constitutes a hooking mechanism. Since a supporting relationship in which the front and rear relative translational movement is possible is set between the stop member and the support member, the plurality of heald frames on the hooking member move in parallel in the front and rear direction without tilting. It has an excellent effect that the heald frame can be easily attached.
