BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for exchanging a completed cross roll and an empty cross roll.

[0002]

2. Description of the Related Art Automatic cross-roll changers of this type are disclosed in Japanese Patent Laid-Open No. 60-17957 and Japanese Utility Model Laid-Open No. 60-1771.
No. 43 publication. The automatic cross roll changers in both publications are all installed on the cross roll carrier side. When the cross roll on the loom is in the completed winding state, the cross roll carrier receives the call and arrives at the transfer work position in front of the loom. When the cross-roll carrier arrives at the transfer work position in front of the loom and stops, the automatic cross-roll exchange device performs a series of cross-roll exchange operations. The cross roll (hereinafter, referred to as a full roll) on the loom that has been completely wound is transferred to the transport vehicle side, and the empty cross roll (hereinafter, referred to as an empty roll) on the transport vehicle is transferred to the loom side. Next, the cloth cutting mechanism that constitutes the automatic cloth roll changing device cuts the woven fabric between the empty roll and the full roll. Therefore, the cross roll can be replaced without stopping the loom.

Problems to be Solved by the Invention JP-A-60-1795
The use of the cross roll carrier as disclosed in Japanese Patent Publication No. 6 and Japanese Utility Model Laid-Open No. 60-177143 is premised on that one machine is responsible for automatic cross roll exchange in a plurality of loom. Therefore, it may take some time for the cross-roll carrier to arrive at the loom requiring the cross-roll exchange even when the cross-roll exchange comes. If the arrival of the cross-roll carrier takes a long time, there is a problem that the woven fabric weaving length greatly exceeds a predetermined length, and if the arrival of the cross-roll carrier is delayed, the loom must be stopped.

In Japanese Patent Application Laid-Open No. 1-285549, a full load on a temporary carriage that can be switched between a standby position close to the cloth winding position and a delivery position for delivering a full roll to a cross roll transport vehicle. A cross roll transfer device having a temporary roll position is disclosed. With this conventional device, weaving can be continued with the full roll temporarily placed at the full roll temporary placement position, and the arrival of the cross roll transport vehicle can be waited with sufficient time. Therefore, it is possible to increase the number of looms carried by one cross roll carrier. However, a temporary carriage must be installed for each loom, and the cost disadvantage is unavoidable. Moreover, the floor space for switching and disposing the temporary trolley becomes large, and the floor of the entire loom factory becomes large.

In Japanese Laid-Open Patent Publication No. 2-138059, a cross roll replacement vehicle and a cross roll transport vehicle are used, and the cross roll transferred from the loom by the cross roll exchange vehicle is a cross roll transport vehicle at a predetermined location. Be transferred to. Due to such division of roles, the traveling distance of the cross-roll exchange-dedicated vehicle is shortened, and the number of weaving looms per cross-roll exchange-dedicated vehicle is increased. However, the number of vehicles for exclusive use of cross roll transfer is required to be larger than the number of vehicles for exclusive use of cross roll exchange, and there is no advantage in reducing the number of exclusive vehicles as a whole.

[0006] It is an object of the present invention to provide a cross roll exchanging device capable of exchanging cross rolls without stopping weaving and further reducing the space of a floor of a loom factory.

[0007]

An empty roll insertion mechanism provided on the loading carriage, a cloth cutting mechanism provided on the temporary loading carriage for cutting the woven fabric continuous from the full roll on the full roll temporary placement position to the loom side, and the cross roll A connector provided on the temporary carriage for obtaining a driving force from the loom side to the driving mechanism for performing the exchange operation, and a connector for connecting to the connector to supply the driving force from the loom side to the driving mechanism. A cross roll changing device having a connector provided on the loom side is configured.

According to the second aspect of the present invention, the transfer wheel mechanism for movably supporting the temporary trolley in a direction different from the switching arrangement direction between the storage position and the cross roll transfer position is incorporated into the temporary trolley. For transfer to the retracted position above the wheels of the transfer wheel mechanism for switching the placement vehicle between the storage position and the cross roll transfer position, and the grounding position below the wheels of the transfer wheel mechanism A switching arrangement mechanism for switching and arranging wheels has been incorporated into the transport wheel mechanism.

[0009]

[Function] When the time to replace the cross rolls comes, the temporary trolley with the empty rolls is carried to the storage position in the loom. The connector on the temporary carrier side and the connector on the loom side are connected to each other, and the driving force for performing the cross roll exchange is supplied from the loom side to the temporary carrier side. By this power supply, the full roll on the cloth winding position is discharged and moved to the full roll temporary position by the discharging operation of the full roll discharge transfer mechanism. The temporary placement carriage on which the full roll is placed moves to the full roll transfer position side, and then the empty roll on the empty roll temporary placement position is moved to the cloth winding position by the inserting operation of the empty roll insertion mechanism. The woven fabric extending from the full roll temporary placement position is connected to the loom side, and the woven fabric cutting mechanism on the temporary placement carriage cuts the woven fabric. When the cross roll exchange is completed, the temporary carriage side connector and the loom side connector are removed. Then, the temporary trolley equipped with the full roll is carried to a place where the full roll is stocked.

In the structure provided with the transport wheel mechanism, the wheels of the transport wheel mechanism are in the retracted position during the cross roll exchange operation. When transporting empty rolls and full rolls, the wheels of the transport wheel mechanism are installed to support the temporary carrier. If the rolling direction of the wheels of the transport wheel mechanism and the rolling direction of the wheels of the transfer wheel mechanism are made orthogonal to each other, the movement of the temporary carriage along the loom row can be changed to the storage position in the loom. It will be easy.

It

When the temporary trolley 13 is moved to the position shown in FIG. 1, the worker connects the connector 58 and the connector 60 and the connector 59 and the connector 61. Then, when the raising command switch 63 is turned on, the cross exchange control computer C ₁ reverses the lifting motor 53. The reverse rotation of the lifting motor 53 causes the support frame 48 and the transport wheels 3 to be rotated.
3 rises. When the support frame 48 rises and the limit switch 17A is turned on, the cross exchange control computer C ₁
Stops the reverse rotation of the lifting motor 53. Due to this reverse rotation stop, the transfer wheels 33 are located above the transfer wheels 45 and 46, and the transfer wheels 45 and 46 are grounded.

After the transfer wheels 45 and 46 are grounded, the operator releases the connected state of the clutch mechanism 57. This disconnection allows the transfer wheels 45 and 46 to roll freely, and the temporary carrier 13 can be manually moved in the front-back direction of the loom. When the worker moves the temporary placement vehicle 13 to the storage position of FIG. 2, the detected object 42 encounters the proximity switch 41, and the proximity switch 41 is turned on. In response to the ON signal from the proximity switch 41, the cross exchange control computer C ₁ enters the cross roll exchange standby state. After arranging the temporary trolley 13 at the storage position, the worker switches the clutch mechanism 57 to the connected state. By this switching, the transfer wheels 45 can be driven by the transfer motor 14.

When the count number of the origin signal reaches a predetermined number n ₂ , the loom control computer C ₀ outputs a cross exchange signal to the cross exchange control computer C ₁ . The cross exchange control computer C ₁ commands the forward rotation of the transfer motor 14 in response to the input of the cross roll exchange signal. Motor 1
4 by the forward rotation, the temporary carriage 13 moves from the storage position of FIG.
Move to the most forward position.

While the temporary trolley 13 is moving, the roll-out prevention release levers 19A and 19B are set to the cross roll stoppers 12A and 1B.
2B, the cross roll stoppers 12A and 12B are displaced downward from the outflow prevention position shown in FIGS. 1 and 2. Next, the kick-out levers 18A and 18B come into contact with the large-diameter shaft portion 4a of the full roll 4B on the cloth winding position P ₁ , and the full roll 4B is transferred to the pair of rollers 16A and 16B on the stand portions 15A and 15B. Placed. That is, the pair of rollers 16A and 16B become the full roll temporary placement position P ₂ . When the full roll 4B is placed on the full roll temporary placement position P ₂ , the tooth portion 4c of the full roll 4B meshes with the gear 27.

The temporary trolley 13 on which the full roll 4B is placed is shown in FIG.
When moving toward the most forward position shown in 4, full roll 4B

Responds to this ON signal by stopping the operation of the transfer motor 14.
Stop. When the transfer motor 14 is stopped, the temporary carrier 13
It stops at the most advanced position in FIG.

After the temporary carriage 13 is stopped, the cross exchange control computer C ₁ commands the motor 22 to rotate forward by a predetermined amount.
The normal rotation of the motor 22 causes the empty roll support arms 20A, 2
0B moves down to the position shown in FIG. 4, and the empty roll 4A on the hand 20a pushes down the woven fabric W between the loom and the full roll 4B. The woven fabric W extending from the full roll 4B to the woven fabric winding position P ₁ side comes into contact with the guide rail 29 and the nozzle pipe 36, and then comes into contact with the peripheral surface of the large diameter shaft portion 4a of the empty roll 4A. Pass the lower side.

Next, the cross exchange control computer C ₁
Commands the electromagnetic clutch 28 to be turned on. Electromagnetic clutch 2
When 8 is turned on, the clutch plate 28a is pressed against the gear 27,
The gear 27 cannot rotate relative to the stand portion 15A. Therefore, the full roll 4B is prevented from rotating on the full roll temporary placement position P ₂ . Weaving continues even when the temporary trolley 13 is away from the storage position, and the woven cloth W is woven from the cloth guide bar 5 side to the empty roll 4 on the hand 20a.
It is sent to the A side.

After the motor 22 rotates in the normal direction by a predetermined amount, the cross exchange control computer C ₁ commands the reverse rotation of the idle roll rotating motor 21. The empty roll 4A is reversed on the hand 20a, and the woven fabric W in contact with the peripheral surface of the coarse large-diameter shaft portion 4a is pulled in the rotation direction of the empty roll 4A. This pulling action increases the tension of the woven fabric W between the full roll 4B and the empty roll 4A, and when the tension reaches a predetermined value, the rotation of the torque motor type empty roll rotation motor 21 is stopped. In this state, the tension of the woven fabric W between the full roll 4B and the empty roll 4A is in a state suitable for cutting.

After the reverse rotation of the idle roll rotation motor 21, the cross exchange control computer C ₁ commands the forward rotation of the cutter driving motor 30 and the excitation of the electromagnetic valve 43. The cutter 32 runs from the support arm 20A side toward the support arm 20B side and cuts the woven fabric W. Simultaneously with this cutting, the nozzle pipe 36 injects air toward the empty roll 4A as shown by the arrow in FIG. The woven cloth cut end W ₁ on the empty roll 4A side is wound around the peripheral surface of the empty roll 4A by the jetting action of the nozzle pipe 36. After the cloth is cut, the cloth exchange control computer C ₁ commands the reverse rotation of the cutter drive motor 30 in response to the input of the cutter detection signal. This reverse rotation causes the cutter 32 to return to the standby position.

After cutting the woven cloth W, the cloth replacement control computer C ₁ rotates the idle roll rotation motor 21 in the normal direction and the motor 2 rotates.
Instruct to reverse the predetermined amount of 2. The reverse rotation of the motor 22 causes the empty roll support arms 20A and 20B to move upward, and the empty roll 4
A is aligned with the height position of the cloth winding position P ₁ .
The woven fabric cut end W ₁ on the loom side is wound around the empty roll 4A by the normal rotation of the empty roll rotation motor 21. From this state, the cross exchange control computer C ₁ commands the reverse rotation of the transfer motor 14. Due to the reverse rotation of the transfer motor 14, the temporary carrier 13 moves backward toward the storage position. That is, empty roll 4
A moves toward the cloth winding position P ₁ while winding the cloth cutting end W ₁ on the loom side.

Proximity switch 4 associated with the retreat of temporary vehicle 13
The reverse rotation of the transfer motor 14 is stopped by the encounter between 0 and the detected object 42, and the temporary placement carriage 13 is stopped at the empty roll insertion position shown in FIG. Due to this backward movement stop, the empty roll 4A on the hand 20a is inserted at the cloth winding position P ₁ .

After the empty roll is inserted, the transfer motor 14 rotates in the normal direction, and the temporary carrier 13 moves forward. In this forward movement, the transfer motor 14 stops due to the encounter between the proximity switch 41 and the detected body 42, and the temporary carriage 13 stops at the most forward position in FIG. After the temporary carriage 13 is loaded with the full roll 4B and stopped at the most forward position, the worker disconnects the connector 58 and the connector 60, and then disconnects the clutch mechanism 57.
This disconnection allows the transfer wheels 45 to freely roll, and the temporary carriage 1 supported by the transfer wheels 45 and 46.
3 can be moved manually.

The operator pulls out the temporary trolley 13 from the inside of the loom to the vicinity of the arrangement position shown in FIG. If the descent command switch 62 is turned on at this pull-out position, the elevating motor 53 will rotate normally,
The support frame 48 and the transportation wheels 33 descend. The descending support frame 48 turns on the limit switch 17B, and the cross exchange control computer C ₁ stops the forward rotation of the lifting motor 53 in response to this ON signal. Transporting wheel 33 that has descended
Is grounded, and the temporary carrier 13 can be transported along the row of loom. The worker pushes the temporary trolley 13 equipped with the full roll 4B to the full roll stock location.

In this embodiment, when the cross rolls are about to be replaced, if the temporary carriage 13 is stored in the storage position in the loom, the full roll 4B and the empty roll 4A can be replaced by the temporary carriage 13 and the loom. Between and. The number of looms to be carried by each temporary carriage 13 is smaller than that of the cross roll exchange vehicle disclosed in JP-A-60-171956, but the cross roll exchange is performed without stopping the weaving. be able to.

In the temporary carriage system disclosed in Japanese Patent Laid-Open No. 1-285549, the cross roll can be replaced without stopping the weaving, but there is a problem in the number of the temporary carriages and the floor space. Since the temporary carrier 13 of this embodiment provided with the transport wheel mechanism 31 also serves as a conventional cross roll exchange vehicle, the number of temporary carrier 13 can be much smaller.

The temporary carriage 13 at the most forward position is considerably out of the loom. If a cross-roll exchange vehicle that runs automatically is used, the travel route of the cross-roll exchange vehicle must be set so as not to interfere with the temporary carriage at the most forward position. Such travel route setting leads to an increase in floor space in the loom factory. The temporary trolley | bogie 13 of a present Example moves an operator using the wheel mechanism 31 for conveyance. Therefore, it suffices to secure a transfer path space for the temporary storage vehicle 13 so as not to interfere with the temporary storage vehicle 13 at the storage position. Securing such a transportation route space leads to a reduction in floor space in the loom factory.

The rolling directions of the transfer wheels 45 and 46 and the rolling direction of the transfer wheel 33 are made orthogonal to each other, and the empty roll temporary placement position P is set.
₃ empty roll 4A and configurations set the rolling direction of the conveying wheel 33 in the longitudinal direction of the full roll temporary location position P ₂ on the full roll 4B also contributes to a reduction in floor space. That is, in the longitudinal direction of the cross roll on the temporary carrier 13, the temporary carrier 13
By moving, the transfer route space of the temporary carrier 13 is minimized. Therefore, the floor space between the loom row and the loom row, which is the transport path of the temporary trolleys 13, can be reduced.

The present invention is, of course, not limited to the above-mentioned embodiment, and for example, a rail for a transport wheel may be laid in a factory and the transport wheel may be driven. In this case,
Driving power can be automatically carried by mounting a battery on the vehicle or supplying it from the rail. Further, the transfer wheels may be omitted and the transfer wheels may also be used for transfer.

[0049]

As described in detail above, according to the present invention, when the time to replace the cross roll is approaching, a temporary carriage equipped with an empty roll is arranged in the storage position of the loom, and the power of the loom is used to replace the cross roll. Since the temporary carriage equipped with full rolls is moved to a predetermined place by performing the operation, the loom carrying number per temporary carriage does not drop much compared to the conventional cross roll exchange vehicle. Moreover, it is possible to perform the cross roll exchange without stopping the weaving, and it is possible to reduce the floor space of the loom factory.
