Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a machine setting device used when mounting and removing a warp beam and a member through which a warp is passed from and on a loom. is there.

(Prior Art) Japanese Unexamined Patent Publication (Kokai) No. 52-49358 discloses a device for performing a machine setting operation in which an empty warp beam on a loom whose warp has been consumed is removed from the loom and a full warp beam is mounted on the loom instead. There is a weaving device. This device supports the cloth take-up roller with the frame on the floor to form the first half, and the transporter with the dropper box and the full warp beam forms the second half. I am trying to transfer to the first half. Then, the full warp beam is transported to the front half by a transport vehicle and attached to the front half by a device provided in the transport vehicle.
In this full-warp beam, the warp threads are previously inserted through threading members such as heddle and reed, and the operation of joining the new full-warp beam side warp threads and the woven cloth side warp threads one by one on the loom is omitted. We are trying to reduce the time.

(Problems to be Solved by the Invention) In the above-described trial weaving device, the full warp beam is supported on the base of the carrier, and the threading member is held in a state of being hung from the upper hanger. After the beam is attached to the front half of the loom by the carrier, the hanger is projected toward the loom and the threading member is moved to the front half of the loom to be attached. At this time, the distance between the threading member and the full warp beam changes, and the magnitude of the tension applied to the warp drawn out from the full warp beam to the threading member changes. Therefore, thread breakage or insufficient tension due to excessive tension occurs. The warp may be entangled due to the looseness of the yarn, which may adversely affect the weaving operation. Therefore, the operator manually rotates the full warp beam in either forward or reverse directions to pull out and wind the warp, thereby adjusting the tension of the warp. However, since this work is performed during the transfer of the full warp beam, there is a problem in safety, and it is laborious and complicated because the worker is forced to take an unreasonable posture.

Structure of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention removes an empty warp beam from a loom and mounts a full warp beam on the loom on a support base movable on the floor. The warp beam transfer means is installed to reciprocate between the standby position of the full warp beam and the machine work position, and at least the heddle and reed through which the warp of the full warp beam is inserted can be removed. The moving member transfer means for supporting the warp beam transfer means and the through member transferring means are moved from the standby position to the machine work position and from the machine work position. When moving to the standby position, a warp beam rotating means that positively rotates the warp beam forward or reverse and maintains the warp tension almost always constant is provided. Those were.

(Operation) By adopting the above means, the present invention moves the warp beam transfer means and the through member transfer means from the standby position to the machine work position and from the machine work position to the machine work position. When moving, the warp beam rotating means positively rotates the warp beam in the forward or reverse direction to keep the tension of the warp yarn substantially constant.

Further, in the present invention, since the warp tension can be adjusted by rotating the warp beam forward or backward, there is no need to provide a mechanism such as a tension lever, a tension spring, a back roller, etc. on the side of the device, and the structure is simplified. The cost can be reduced.

This warp beam rotating means is composed of a hydraulic motor 88 rotatable in forward and reverse directions, a speed reducer 90 mounted to the hydraulic motor 88 via a support bracket 89, and a friction roller 91 connected to the speed reducer 90. The friction roller 91 is configured to come into contact with one flange 81a of the full warp beam 81 by the operation of the hydraulic cylinder 86.

The hydraulic motors 24, 25, 88 and the hydraulic cylinders 11, 12, 38, 39, 41, 42, 43, 44, 70, 79, 80, 86 are on the control device installed in the automatic guided vehicle 1. It is controlled by operating a push button (not shown).

Now, the operation of the mechanism device configured as described above will be described in detail below.

After the warp beam detector on the loom 3 and the warp cutting detection device through which the warp yarns are passed, the heddle frame, and the warp member such as the reed are removed, the full warp beam 81, the warp cutting detection device 55, the heddle frame 71, and the reed 72 are removed. The machine-moving device mounted in the state shown in FIG. 1 and standing by in the machine-preparing room is moved along the groove rail 4 to the machine-working position behind the loom 3. In this state, the hanging frames 56, 57 and the heald frame 71 of the warp cutting detection device 55
And reed 72 are supporting hooks 66 and 67 and holding arm 6 respectively.
Suspended by 8,69, full warp beam 81 is a transfer lever
It is supported by the first support grooves 76a and 77a of the 76 and 77. The warp T of the full warp beam 81 is passed through the heddle frame 71 and the reed 72 through the dropper of the warp cutting detector 55.

Here, by operating the push button of the control device of the automatic guided vehicle 1, the second support grooves 76b and 77b of the transfer levers 76 and 77 are moved to the first position by the reverse rotation of the hydraulic motors 24 and 25 and the operation of the hydraulic cylinders 79 and 80. Instead of the support grooves 76a, 77a, the shaft 81a of the full warp beam 81 is engaged, and in this state, the hydraulic motors 24, 25 are normally rotated to place the full warp beam 81 on the mounting position 78a. Then, the hydraulic cylinders 38, 39 provided to the holder arm 34 are operated, the hydraulic cylinders 41, 42 are operated, the warp cutting detection device 55 is arranged above the mounting position on the loom 3, and the heddle frame 71 and the reed 72 Are placed in the mounting position. In this state, the hydraulic cylinder 70 is operated, the heald frame 71 and the reed 72 are released from the pressing arms 68, 69, and are manually attached to the loom 3. Next, the hydraulic cylinder 41 is operated and the warp cutting detection device 55 is lowered and placed on the loom 3. After that, the hanging plates 51, 52 are rotated, the warp cutting detecting device 55 is detached from the hanging plates 51, 52, and mounted on the loom 3.

As described above, the warp cutting detection device 55, the heddle frame 71, the reed 72
In the process of moving the loom 3 to the loom 3 side, the distance between the thread separating point D of the full warp beam 81 and the thread receiving point R of the warp cutting detecting device 55 changes, and the warp cutting detecting device 55 and the like are attached to the loom 3. When the position is reached, the distance between both D and R becomes the longest. As the distance changes, the tension state of the warp T between the two D and R changes, and the warp T may be cut. In order to prevent this, when the warp cutting detection device 55 starts moving, the hydraulic motor 88 is driven in the normal direction to rotate the full warp beam 81 in the direction of arrow A through the friction roller 91, and the full warp beam 81 causes the warp yarn T to move. Pull out.
Therefore, the warp yarn T between the full warp beam 81 and the warp yarn cutting detector 55 is prevented from being excessively strained.

Then, the hydraulic motors 24 and 25 on the auxiliary table 13 are normally rotated for a predetermined time. The forward motion of the hydraulic motors 24 and 25 is the chain gear 28,
It is transmitted to the pinions 20 and 21 via 29 and 22 and 23, and the pinions 20 and 21 roll on the racks 5 and 6 while meshing with the racks 5 and 6. Therefore, the wheel 1 fixed coaxially with the pinion 20, 21
4,15 roll on fixed rails 7,8 and movable rails 9,10,
The auxiliary table 13 is moved from the standby position on the transport vehicle 2 to the machine-position position. In the process of moving and arranging the auxiliary table 13, the hydraulic cylinders 79 and 80 are operated, and the full warp beam 81 is temporarily placed on the temporary placement position 78b of the support bracket 78 as shown by the chain line in FIG. The full-warp beam 81 does not naturally rotate due to the friction roller 91 that is in contact with the flange 81a.

Even when the above-mentioned full warp beam 81 moves, the yarn receiving portion R of the warp cutting detection device 55 and the full warp beam 81
The distance from the yarn separation point D of No. changes. At this time,
The hydraulic cylinder 86 is driven by the button operation, and the warp beam rotating means is moved following the full warp beam 81. At the same time, by appropriately driving the hydraulic motor 88 and rotating the full warp beam 81, the tension of the warp yarn T between the yarn receiving portion R and the yarn separating portion D can be adjusted.

Since the support bracket 89 in the present embodiment rotates together with the shaft 73, the friction roller 91 does not interfere with the flange 81 of the warp beam 81 even if the transfer lever 77 is at an arbitrary position.
It is surely pressed against a. When the empty warp beam is removed from the loom, the hydraulic motor and the hydraulic cylinder are driven in the reverse order to the above.

As described above, in this embodiment, the warp cutting detection device 55, the heddle frame 71, the reed 72, and the full warp beam 81 are used during the machine work.
According to the movement of the friction roller 91, the friction roller 91 is appropriately rotated in the forward direction or the reverse direction, whereby the full warp beam 81 is rotated and the warp yarn T is wound and pulled out. Therefore, a substantially constant tension is always applied to the warp T between the warp member and the full warp beam 81, and yarn breakage due to excessive tension and entanglement of the warp T due to looseness of the yarn are avoided.

The present invention is not limited to the above-described embodiment, and for example, the tension sensor detects the value of the tension of the warp between the warp cutting detector and the full warp beam,
It is also possible that the controller adjusts the warp beam tension by rotating the full warp beam by rotating the motor of the warp beam rotating means in the forward and reverse directions at any time according to the electric signal sent from the sensor.

As described above in detail, the present invention provides the warp beam transfer means for removing and mounting the empty warp beam and the full warp beam with respect to the loom, and at the same time, for mounting the through member on the loom. A warp beam transfer means and a warp beam transfer means are provided when the warp beam transfer means and the through member transfer means are moved from the standby position to the machine work position and from the machine work position to the standby position. By providing a warp beam rotating means for positively rotating or reversing the warp and keeping the tension of the warp almost always constant, the warp between the warp member and the full warp beam has a substantially constant tension. Since it is possible to avoid yarn breakage due to excessive tension and warp entanglement due to yarn loosening, the work of directly turning the warp beam is omitted. Therefore, it has an effect of being excellent in safety and being easy to work.

Further, in the present invention, it is not necessary to provide a mechanism such as a tension lever, a tension spring and a back roller, so that the structure can be simplified and the cost can be reduced.
