Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art An automatic cross roll changing device of this type is disclosed in Japanese Patent Laid-Open No. 60-17956. The automatic cross roll changing device in this conventional device is installed on the side of the cross roll carrier, and when the cross roll on the loom reaches the winding completion state, the cross roll carrier receives a call and moves to the transfer work position in front of the loom. arrive. 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, and the cross roll on the loom (hereinafter referred to as full roll) is transported. While being transferred to the vehicle side, an 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 cross roll changing device cuts the woven cloth between the empty roll and the full roll, and the woven cloth cutting end on the loom side is wound around the empty roll and the woven cloth on the carrier side is also wound. The cut end is wound into a full roll. The empty roll transferred onto the cloth winding position is operatively connected to a loom drive motor, and winding of the cut end of the cloth around the empty roll is performed by air injection. The empty roll wound with the cut end of the woven fabric by the air jet starts winding the woven fabric. Therefore, it is possible to replace the cross roll without stopping the loom.

[0003]

The use of the cross roll carrier as disclosed in the prior art is based on the assumption that one machine is responsible for automatic cross roll exchange in a large number of looms. The number of machines is a few of all the loom groups. 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 cross roll carrier takes a long time to arrive, 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.

Although there are cases where the above-mentioned cross roll transport vehicle cannot be used from the viewpoint of the space for arranging the loom, in such a case, the loom must be stopped every time the weaving of the woven fabric is completed.

A system in which a cross roll changing device is installed on the loom side is disclosed in Japanese Patent Laid-Open No. 1-97241.
In this conventional device, the full roll at the cloth winding position on the pair of winding drive rollers is pushed out by the push-out lever, and is pushed by the spring force to roll over to the cloth-receiver lever while pushing down the upright cloth-receiver lever. .. Next, the empty roll is dropped and attached to the woven fabric winding position, and the woven fabric between the empty roll and the full roll is cut by a cutter that moves in the width direction of the woven fabric. Therefore, weaving can be performed by temporarily placing the full roll on the pushing lever.

However, in this conventional apparatus, the loom is temporarily stopped during the exchange of the cross rolls. If the loom is not stopped, the take-up drive roller will rotate, and the weight of the empty roll placed on the take-up drive roller will cause the woven fabric to be pressed onto the take-up drive roller. Sent to the side. If such a woven fabric is delivered, the woven fabric between the empty roll and the full roll is loosened, and the woven fabric cannot be cut. Therefore, the suspension of the loom cannot be avoided.

The present invention provides a cross roll exchanging device capable of continuing weaving even when the arrival of the cross roll transport vehicle is delayed and improving the loom operating efficiency even when the cross roll transport vehicle cannot be used. The purpose is to do.

[0008]

Therefore, according to the present invention,
The cloth roll weaving length is detected and a cross roll replacement command means for outputting a cross roll replacement signal when the weaving length reaches a predetermined length, and a full roll on the cloth winding position based on the output of the cross roll replacement signal The full roll discharge moving means for discharging and moving the empty roll to the temporary position, the empty roll mounting means for mounting the empty roll on the standby position to the winding position of the woven fabric after discharging and moving the full roll, and the temporary roll position on the temporary position. Tension applying means for applying tension to the woven fabric extending from the full roll, woven cloth cutting means for cutting the woven fabric extending from the full roll on the temporary position, and the cut empty roll A cloth roll wrapping device for winding the cut end of the woven fabric around the empty roll was installed on the loom to form a cross roll exchange device.

[0009]

When the weaving length of the woven cloth reaches the predetermined length, the cross roll replacement command means outputs the cross roll replacement signal.
The detection of the woven fabric weaving length is performed by counting the number of weft insertions, for example.

When the cross roll exchange signal is output, the full roll on the cloth winding position is discharged and moved to the temporary position by the discharging operation of the full roll discharging and moving means. An empty roll is preliminarily provided at the empty roll standby position on the loom, and when the full roll is discharged and moved to the temporary placement position, the empty roll on the standby position is moved to the cloth winding position by the installation operation of the empty roll installation means. Be done. By replacing the cross rolls at the woven fabric winding position, the woven fabric is connected to the full roll via the empty roll on the woven fabric winding position. The woven cloth extending from the full roll on the temporary placement position is given a tension by the tension applying means, and the woven cloth to which the tension is applied is cut by the cutting operation of the woven cloth cutting means. The woven fabric cut end on the empty roll side is wound around the empty roll on the woven fabric winding position by the winding operation of the cloth end winding means.

The cross roll exchanging device for performing the above series of cross roll exchanging is installed on the loom side, and the full roll on the temporary placement position interferes with the cross roll on the woven fabric winding position during the diameter increase. Weaving can be continued while not in use. That is,
By appropriately setting the distance relationship between the cloth winding position and the temporary placement position, weaving can be performed while waiting for the arrival of the cross roll transport vehicle for a long time.

The second bracket piece 30b, rolling on 31b is continued by inertia after straight rolls on the first bracket piece 30a, 31a, the small-diameter shaft 8a is disengaged from the guide edge 30b _1, 31b ₁ is Absent. Guide edge 30b _1, 31b small diameter has rolling on ₁ 8a is temporary置凹portion _30c, Mari included fitted to 31c, the support rollers 41, 42
Supported by.

When the small-diameter shaft 8a is fitted into the temporary placement recesses 30c _and 31c, the full roll take-up motor 43 is operating in reverse, and the drive roller 43a moves in the direction opposite to the rolling direction of the full roll 8A. It's spinning. Therefore, full roll 8A
The gear 8d is a rubber 43a ₁ of the rotating driving roller 43a.
Fully roll-up motor 43 that makes smooth contact with the peripheral surface.
The impact on There is a possibility that an operator may enter the rolling of the full roll 8A that rolls from the cloth winding position S ₁ toward the temporary placement position S ₂ , but the presence of this worker is detected by the area sensors 44 and 45. To be done. The area sensors 44 and 45 are in operation while the roll brackets 30 and 31 are pivoting and descending from the storage position to the transfer position, and are full as long as the worker has not retracted from the detectable area of the area sensors 44 and 45. The roll brackets 30 and 31 do not rotate down to the transfer position. Therefore, the full roll 8A moves from the cloth winding position S ₁ to the temporary placement position S ₂ unless the worker retreats from the detectable areas of the area sensors 44 and 45.
It does not roll over to ensure the safety of workers. When the full roll brackets 30 and 31 are lowered to the transfer position, the operation of the area sensors 44 and 45 is stopped.

When the full roll 8A reaches the temporary placement position S ₂ ,
The proximity switch 94 detects the gear 8d and outputs a pulse signal corresponding to the rotation speed of the full roll 8A. In the unlikely event that the full roll 8A does not reach the temporary placement position S ₂ , the control computer C ₁ outputs a weaving stop signal to the loom control computer C ₀ and the full roll take-up motor 43 The operation is stopped and the alarm device 96 is activated.

The control computer C ₁ has a proximity switch 94.
When there is a pulse signal input from, the reverse rotation operation of the full roll winding motor 43 is stopped, the proximity switch 93 is operated, and the empty roll winding motor 25 is further operated.

The rotational speed of the idle gear 6 due to the operation of the idle roll winding motor 25 is set to exceed the rotational speed of the idle gear 6 due to the operation of the loom drive motor. Therefore, the idler gear 6 is rotated by the operation of the idle roll winding motor 25, and the operative connection between the clutch plates 20b and 21 is substantially released. That is, the clutch plate 2
After the operation of the empty roll winding motor 25 in which relative rotation occurs between 0b and 21, the motor 71 operates in the forward direction, and the cutter levers 72 and 73 rotate and rise from the standby position as shown in FIG. The arms 82 and 83 tilt rearward. The empty roll 8B is formed by tilting the support arms 82 and 83.
Is released from the supporting action of the support arms 82 and 83, and falls from the standby position toward the cloth winding position. The empty roll 8B is dropped by a guide path (not shown) and the auxiliary guide 8
It is guided to the woven fabric winding position S ₁ by the guide path between the 7, 88 and the auxiliary guide plates 91, 92.

As shown in FIG. 17, the small diameter shaft 8a of the empty roll 8B abuts on the cross roll stoppers 46 and 47.
The spring force of the return springs 67 and 68 is set to a strength capable of supporting the empty roll 8B, and the empty roll 8B is temporarily stopped and supported on the cross roll stoppers 46 and 47 immediately before the cloth winding position S _1. ..

The fall of the empty roll 8B onto the cross roll stoppers 46 and 47 is stopped while the cutter levers 72 and 73 are rotating and rising, and when the cutter levers 72 and 73 reach just before the cutting position, the pushing members 89 and 90 are pushed. Is empty roll 8
It contacts the small diameter shaft 8a of B. From this state, the cutter levers 72 and 73 are rotated up to the cutting position, and the empty roll 8B
The small-diameter shaft 8a is pressed by the pushing members 89 and 90 toward the bearing recesses 9a and 10a. This pressing action exceeds the spring force of the return springs 67 and 68, and as shown in FIG. 18, the small diameter shaft 8a moves to the cross roll stoppers 46 and 47.
Is pushed down to fit into the bearing recesses 9a, 10a. That is, the empty roll mounting means is composed of the support arms 82 and 83, the auxiliary guides 87 and 88, the pushing members 89 and 90, the auxiliary guide plates 91 and 92, and the motor 71. 8B is installed at the cloth winding position S ₁ .

When the empty roll 8B is pushed into the fabric winding position S ₁ , the gear 8d meshes with the idle gear 6. The idler gear 6 is rotating by the operation of the idle roll winding motor 25, and the gears 8d and 25a are smoothly meshed with each other.

When the cutter lever 73 is rotated to the cutting position, the limit switch Ls ₄ is turned on and the motor 71
Stops working. In the state where the cutter lever 73 is pivotally arranged at the cutting position, the sharp end of the cloth insertion bar 97 is pressed against the peripheral surface of the empty roll 8B via the woven cloth W by the spring action of the pressing springs 97a and 97b.

When the empty roll 8B is mounted at the cloth winding position S ₁ , it is rotated in the cloth winding direction by the empty roll winding motor 25, and the proximity switch 93 causes the proximity switch 93 to move.
A pulse signal corresponding to the rotation speed of B is output. In response to this pulse signal, the control computer C ₁ operates the full roll winding motor 43 in the normal direction.

As shown in FIG. 19, a cloth gripping groove 8e is formed on the peripheral surface of the large diameter shaft 8b of the cross roll along the axial direction, and the cloth gripping groove 8e is formed along with the rotation of the empty roll 8B. Encounter the insertion bar 97, and the cloth insertion bar 97 is held by the cloth gripping groove 8e.
Fit in. This fitting action prevents rotation of the empty roll 8B, and the woven cloth W is held by the cloth grip groove 8e.
It is inserted inside. Due to this rotation stop, the torque motor type empty roll winding motor 25 is not driven to rotate, and the rotational drive force on the loom drive motor side is absorbed by the torque limiter 86 between the surface roller 4 and the drive gear 19.

The proximity switch 94 outputs a pulse signal corresponding to the rotation speed of the full roll 8A caused by the forward rotation of the full roll winding motor 43. When the pulse frequency f ₁ becomes equal to or less than the set number F ₁ , the cutter drive motor 75 operates in the normal direction, and the disc cutter 80 starts traveling from the right side frame 1 side to the left side frame 2 side. At the same time, the electromagnetic valve V ₁ is excited and the winding nozzle 81 starts jetting, as shown in FIG.

The set number F ₁ is the empty roll 8B and the full roll 8A.
Is a standard for grasping the tension of the woven fabric W between the woven fabric W and the woven fabric W, and this value is the rotation of the torque motor type full roll winding motor 43 when the woven fabric W has a suitable fabric tension. It is the pulse frequency corresponding to the number. As the tension of the woven cloth W increases, the rotation speed of the full roll winding motor 43 decreases. Therefore, when the pulse frequency f ₁ becomes equal to or less than the set number F ₁ , the tension of the woven fabric W becomes a tension suitable for cutting by the disc cutter 80.
Smoothly cuts the woven cloth W in an appropriate tension state.

Cutter levers 72 and 73, support bar 7
4, when the drive pulse number m ⁺ for the stepping motor type cutter drive motor 75 that constitutes the cloth cutting means together with the drive wire 77, the cutter bracket 79 and the disc cutter 80 reaches the set number M, the cutter drive motor 7
The operation of 5 stops. The set number M is set so that the disk cutter 80 moves a distance that allows the woven cloth W to be completely cut.

After the normal rotation operation of the full roll take-up motor 43 is started, the operation of the full roll take-up motor 43 and the proximity switch 94 is stopped when the detection pulse number n output from the proximity switch 94 reaches the set number N. The woven fabric cutting end W ₁ on the full roll 8A side of the woven fabric W cut by the disk cutter 80 hangs down from the peripheral surface of the full roll 8A, but the full roll 8A is kept until the detected pulse number n reaches the set number N. By continuing to turn, the woven fabric cut end W ₁ is wound around the peripheral surface of the full roll 8A, and the hanging state of the woven fabric cut end W ₁ disappears. In this state, the full roll 8A waits for the arrival of the cross roll carrier.

After the disc cutter 80 cuts the woven fabric W forward,
The cutter drive motor 75 operates in the reverse direction, and the disk cutter 8
0 moves back from the left side frame 2 side toward the right side frame 1 side. When the drive pulse number m ⁻ for the cutter drive motor 75 reaches the set number M, the operation of the cutter drive motor 75 stops and the disc cutter 80 returns to the standby position.

As shown in FIGS. 20 and 21, the empty roll 8
The cut end W ₂ of the woven cloth on the B side is wound around the peripheral surface of the empty roll 8B by the jet of the winding nozzle 81. Peripheral surface of the large diameter shaft 8b of the cross roll is formed in a rough surface, fabric cutting edge W ₂ is attached to the rough circumferential surface of the large-diameter shaft 8b.

After the cut end W _{2 of the} woven cloth is wound around the empty roll 8b, the electromagnetic valve V ₂ is excited and the drive rod 18a of the air cylinder 18 projects. As shown in FIG. 22, the meshing state between the pawl member 14 and the ratchet wheel 13 is released by the extension operation of the air cylinder 18. In this disengaged state, the leaf spring 17 moves the ratchet wheel 13
It is strongly pressed against the tip of the claw, and the pressing action of the leaf spring 17 holds the cross guide bar 7 at the position before the disengagement.

Woven fabric cut end W₂After wrapping around, cross guide bar 7
Is in contact with the peripheral surface of the empty roll 8B,
Department W ₂Between the peripheral surface of the empty roll 8B and the cross guide bar 7
Is caught in between. Therefore, due to the operation of the loom drive motor
The tightening of the woven cloth around the empty roll 8B becomes reliable.

With the above, the exchange of the full roll 8A and the empty roll 8B is substantially completed. After the operation of the empty roll winding motor 25 is stopped, the electromagnetic valves V _{1 and} V ₂ are demagnetized, the injection of the winding nozzle 81 is stopped, and the air cylinder 18 is stopped.
The drive rod 18a of is operated. Due to the shortening operation of the air cylinder 18, the pawl member 14 again meshes with the ratchet wheel 13 by the spring action of the leaf spring 17.

After the demagnetization of the electromagnetic valves V _{1 and} V ₂ , the control computer C ₁ outputs a vehicle call signal to the loom control computer C ₀ and operates the area sensors 44 and 45. Temporary position S by actuation of area sensors 44, 45
The existence of the full roll 8A on ₂ is grasped. Motor 38 while the full roll 8A on the temporary location position S ₂ is present is not actuated and does not fully roll bracket 30, 31 is pivotally raised from the transfer position to the storage position.

As shown in FIG. 25, the cross roll carrier 9
8 arrives at the cross roll transfer work position in front of the calling loom in response to the vehicle calling signal from the loom control computer C ₀ . The cross roll transporting vehicle 98 stopped at the cross roll transfer work position is operated by the transfer arm 98a and the transfer hand 98b, and the full roll 8A on the temporary placement position S ₂ is reached.
Are transferred to the carrier. As shown in FIG. 26, the transfer hand 9
8b engages with the annular groove 8c of the full roll 8A. That is, the annular groove 8c is a transfer groove, and this transfer groove 8c is used for discharge rolling of the full roll 8A from the woven fabric winding position S ₁ to the temporary placement position S ₂ .

As shown in FIG. 27, when the full roll 8A is transferred from the temporary placement position S ₂ to the cross roll carrier 98 side,
The control computer C ₁ operates the motor 38 in the reverse direction on the basis of the full roll absence detection signals from the area sensors 44 and 45. Due to this reverse operation, full roll brackets 30, 3
1 moves up from the transfer position to the storage position. When the full roll brackets 30 and 31 are returned to the storage position, the limit switch Ls ₂ is turned on, the operation of the motor 38 is stopped, and the area sensors 44 and 45 are also stopped.

When a small number of cross roll transport vehicles 98 are in charge of cross roll exchange in a large number of loom groups, the cross roll transport vehicle 98 arrives in front of the calling loom after a transport vehicle call signal is output. It can take quite some time. When the cross roll exchanging device is provided in the cross roll conveying vehicle as disclosed in JP-A-60-171956, the cross roll exchanging is performed unless the cross roll conveying vehicle reaches the calling loom. I can't. Therefore, if it takes a long time for the cross-roll carrier to arrive, weaving must be stopped, and the loom operating efficiency decreases.

However, in the present embodiment, the cross roll replacement command means including the loom control computer C ₀ and the rotary encoder 95, the full roll discharge moving means 30,
31, 51, 61, 53, 63, 58, 66, 38, empty roll mounting means 82, 83, 87, 88, 89, 90,
91, 92, 71, woven cloth cutting means 72, 73, 74, 7
5, 77, 78, 80 and cloth edge winding means 7, 13,
All of the cross roll changing devices consisting of 14, 18, 25, 81 and 97 are provided on the loom side, and all the cross roll changing is performed on the loom side regardless of the presence or absence of the cross roll carrier. Therefore, even if the arrival of the cross roll carrier 98 is delayed, the cross roll exchange can be performed without stopping the weaving.

The diameter of the empty roll 8B on the fabric winding position S ₁ increases and eventually interferes with the full roll 8A on the temporary placement position S _2. However, the diameter of the full roll 8A is taken into consideration. By appropriately setting the distance relationship between the take-up position S ₁ and the temporary placement position S ₂ , it is possible to increase the time until the two interfere with each other, and it is possible to practically avoid the weaving stop caused by the cross roll exchange.

The configuration in which such a cross roll changing device is provided on the loom side is effective even when the cross roll transport vehicle cannot be used, and the full roll 8A and the cloth winding position S ₁ on the temporary placement position S ₂ are used. Weaving can continue while it does not interfere with the upper cloth roll. When the cross roll transport vehicle is not used, the weaving may be stopped before the interference between the two, and this stop may be performed by detecting the diameter of the cross roll on the cloth winding position.

Of course, the present invention is not limited to the above-mentioned embodiment. For example, as shown in FIG. 38, the full roll brackets 30, 31 and the cutter levers 72, 73 are rotated and moved up and down by the air cylinders 99, 100. You may do it.

Further, winding of the cut end of the woven fabric around the cross roll can be performed only by attaching the rough peripheral surface to the woven fabric and by spraying the wrapping nozzle, and inserting the woven fabric into the cloth gripping groove of the cross roll. It is also possible to omit the gripping structure.

[0087]

As described above in detail, according to the present invention, the cross roll changing device is provided on the side of the loom to perform the cross roll change. Weaving can be continued while the full rolls do not interfere with each other, and it is possible to avoid weaving stop due to the arrival delay of the cross roll transport vehicle and improve the operation efficiency of the loom.
