Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of use) The present invention relates to a weaving device which is used when a warp beam and a member through which a warp thereof is threaded are attached to and detached from a loom. .

(Prior Art) When installing a warp beam on a loom and passing the warp thread to the weaving machine side (machine work), a new warp beam is considered in consideration of the shortening of the work time, which leads to an improvement in the operating efficiency of the loom. A work procedure in which the warp threads are inserted through a plurality of heddle frames in advance before being mounted is generally adopted. By adopting such a work procedure, it is not necessary to tie a new warp beam side warp and a new fabric side warp one by one on the warp path from the warp beam on the loom to the heddle frame. Time can be shortened.

Japanese Unexamined Patent Publication No. 52-49358 discloses an example of a device for carrying and transferring a warp beam and a heddle frame in which the warp thereof is inserted. In this device, a horizontally expandable arm is supported by a pair of elevating columns, and a hook member is connected to the tips of both arms, so that the heddle frames are collectively hooked and suspended by the hook members. It is supposed to be given down.

(Problems to be solved by the invention) However, in the hanging suspension system as described above, it is difficult to align the arm with a relatively narrow gap between the upper frame of the heald frame and the upper rod for heald tensioning. However, there is a possibility that the heddle frame will be damaged by this erroneous operation.

(Means for Solving the Problems) Therefore, in the present invention, a plurality of heald frames through which warp beams of warp beams are inserted can be collectively grasped and released by a grasping member, and between the heald frames and between the heald frames and the grasping member. A heald frame transfer means for fixing a heddle frame transfer means having a cushioning material interposed between them and a warp beam transfer means for mounting a full warp beam on a loom and removing an empty warp beam from the loom are constituted as a machine setting device.

(Operation) That is, by lowering the gripping member from above to a position for gripping a plurality of heald frames on the loom, the cushioning material is interposed between the heald frames and between the heald frames and the gripping members. It will be. Therefore, by operating the gripping member in the direction in which the heald frame is gripped, each heald frame is gripped via the cushioning material, and transfer is possible without fear of damage to the heald frame.

35, 37, 38, 39, 40, 71, 72 are controlled by operating push buttons (not shown) on a control device installed in the automatic guided vehicle 1.

Now, as shown in FIG. 1, the warp beam 73, which is mounted and supported on the support bracket 70, is passed through the warp cutting detection device 64, the heddle frame 63 and the reed 75 via the back roller 74.
Next, the operation of the mechanism device of the present embodiment when the mechanism work is consumed and the mechanism work is required will be described below.

In the state shown in FIG. 1, the machine setting device standing by in the machine preparation preparation room is moved along the groove rail 4 to the machine operation position behind the loom 3. The fixed gripping arms 49, 50 are attached to the connecting bar 48 according to the width of the loom 3, and the large diameter eccentric portions 53a, 54a are pivotally arranged downward by the pivoting operation of the position regulating shafts 53, 54. As a result, the movable gripping levers 51, 52 are restricted to the released position by the action of the tension springs 57, 58.
The hydraulic cylinders 11 and 12 are operated in the machine work position, and the movable rails 9 and 10 are laid between the carriage 2 and the side frame 3a of the loom 3 with the front wheels 15 placed thereon.
Subsequently, the forward movement of the hydraulic motors 20 and 21 causes the auxiliary stand 13 to move from the standby position on the carriage 2 to the loom 3 side along the fixed rails 7 and 8 and the movable rails 9 and 10, as shown in FIG. It is moved to the mechanical position. This allows the gripping arms 48-52
The grippers 46 and 47 are arranged above the loom 3 on which the heald frame 63 and the warp cutting detector 64 are mounted. Auxiliary stand 13
The hydraulic cylinders 71, 72 are actuated in the movement process of the transfer levers 68, 69 so that the front end support grooves 68a of the transfer levers 68, 69 are aligned with the warp beam shaft 73a
Move downwards. Subsequently, the hydraulic cylinders 37 to 40 are operated, the grippers 46 and 47 move downward to the mounting position of the warp cutting detection device 64 to grip the warp cutting detection device 64, and the gripping arms 49 to 52 cause the heald frame 63 to move. And moves downward to the height position of the upper frame 63a. As a result, among the cushioning pieces 59a to 60c of the cushioning materials 59 and 60, the inner cushioning pieces 59c and 60c enter between the upper frames 63a of the heddle frames 63, and the outer cushioning pieces 59a, 59b and 60c.
a and 60b contact the upper and lower heald frame upper frames. In this state, the large-diameter eccentric portions 53a, 54a are arranged to rotate upward by manually rotating the position regulating shafts 53, 54 by 180 °,
The lower grip arms 51, 52 are urged to rotate in the grip direction by the action of the tension springs 57, 58. Therefore, according to the pulling force of the tension springs 57, 58, the cushioning materials 59, 60 are pressed into contact between the fixed gripping arms 49, 50 and the lower moving gripping arms 51, 52, and all the heald frames 63 are cushioned by the cushioning materials 59, 50. It is collectively gripped by the fixed gripping arms 49, 50 and the lower moving gripping arms 51, 52 via 60. In this gripping state, between the upper frames 63a of each heald frame 63 and between the gripping arms 4
Since the rubber cushioning materials 59, 60 are interposed between 9 to 52 and the upper frame of the front and rear heald frames, the upper frame 63a of the heald frame 63 and the upper rod 63b for heald tensioning are held by the gripping arm 49.
Not damaged by ~ 52, hence the heald frame 63
Gripping force that can reliably prevent the sliding of the
The spring force of 7,58 can be increased. The spring force of the tension springs 57 and 58 can be easily adjusted by adjusting the screwing positions of the screws 55 and 56.

Subsequently, after the reed 75 is manually transferred onto the protrusions 51a, 52a of the movable gripping arms 51, 52, the warp cutting detection device 64 and the heddle frame 63 are moved to the chain line of FIG. 4 by the operation of the hydraulic cylinders 37 to 40. Moved up to the position. In this pulling up process, the heald frame 63
Is held with sufficient force, the heddle frame 63
Will not slip off. Even when the matching accuracy of the pulling-up directions of the gripping arms 49 to 52 with respect to the guide direction of the heddle frame 63 is not sufficient, the heddle frame 6 is elastically deformed due to the elastic deformation of the cushioning materials 59 and 60.
3 goes along the guide direction, and the heald frame 63 can be pulled up smoothly.

After the warp cutting detection device 64, the heddle frame 63, and the reed 75, which are threading members, are removed from the loom 3, the hydraulic cylinders 71, 72 are operated to support grooves 68a for the transfer levers 68, 69 as shown in FIG. Engages the warp beam shaft 73a. While maintaining this state, the auxiliary base 13 reciprocates by the distance between the mounting position 70a and the temporary placement position 70b by the operation of the hydraulic motors 20 and 21 and the hydraulic cylinder, and the supporting grooves 68b of the transfer levers 68 and 69 are formed. It engages with the warp beam shaft 73a at the position indicated by the chain line in FIG. Then, as shown in FIG. 5, the auxiliary base 13 on which the through members 63, 64, 75 have been transferred returns to the standby position on the transport carriage 2, and the movable rails 9, 10 stand by on the transport carriage 2. After returning to the position, the mechanism device is moved to the mechanism preparation room by the towing of the automated guided vehicle 1.

Transfer of the full-warp beam and the warp member from the machine-mounted device equipped with the full-warp beam and its warp cutting detection device, heddle frame, and reed to the loom is almost the reverse of the above-mentioned transfer order. In this case as well, the heald frame can be mounted smoothly by utilizing the elastic deformation of the cushioning materials 59, 60.

The present invention is of course not limited to the above-mentioned embodiment, and for example, as shown in FIG. 6, the gripping arms 49, 50, 5 are provided with the cushioning pieces 76, 77 which come into contact with the upper frame of the front and rear heald frames.
It can be attached directly to 1,52 standing pieces, or the length of a plurality of cushioning pieces 78 fitted between the heddle frames can be made to differ in sequence, or a core material 79 can be embedded in the cushioning pieces 78. It is also possible to do so. Structure or core material in which the length of the buffer piece 78 is sequentially changed
The presence of 79 makes it easier to insert the buffer piece between the heddle frames.

Further, in the present invention, it is possible to carry out the transfer operation by gripping only the right and left central portions of the heddle frame.

Advantageous Effects of Invention As described in detail above, according to the device of the present invention, a plurality of heald frames through which the warp of the warp beam is inserted can be collectively held and released by the gripping members between the heald frames and the heald frames. Since the heddle frame transfer means is configured by fixing a cushioning material interposed between the heddle frame and the gripping member, the heddle frame can be smoothly removed from the loom and attached to the loom without damaging the heddle frame. It has an excellent effect that it can be performed.
