Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a peg tray transfer device for a spinning machine such as a ring spinning machine and a ring twisting machine.

[0002]

[Prior Art]

 In this type of spinning machine, in order to facilitate automatic pipe changing work by the pipe changing device when changing pipes due to full pipe, empty bobbins were supplied to the front of the spinning machine in a state corresponding to the spindle pitch, and doffing was performed. A carrying device for carrying out the full bobbin is required. As this kind of transfer device, a device for carrying a full bobbin or an empty bobbin via a peg tray has been proposed.

For example, in Japanese Patent Laid-Open No. 57-161133, a peg tray having a locking recess on the lower surface is slidably mounted in a row on a guide rail extending along the spindle row. However, there has been proposed a transfer device that horizontally moves the peg tray by an amount corresponding to the spindle pitch by the reciprocating movement of a drive device having a locking claw that engages with the locking recess of the peg tray. Further, in Japanese Patent Laid-Open Nos. 63-145438 and 63-275727, a peg tray is formed so that it can be mounted in a single row, and the peg tray is reciprocally movable along a spindle row. The transfer member is driven back and forth by a cylinder, and a locking member that restricts the movement of the peg tray and positions the peg tray at a predetermined position when the mounted transfer member is moved back is provided, and the peg tray is sequentially moved by the reciprocating motion of the mounted transfer member. Conveying devices for transferring to a predetermined position have been proposed.

However, the transporting device using the peg tray has a problem in that, when the cotton balls are accumulated on the transfer route of the peg tray, or the bobbin is not properly attached to the peg tray, the bobbin is caught in a part of the machine base. In some cases, the peg tray cannot move along the peg tray transfer route. Further, when the spinning machine is used as a conveyor for a spinning winder in which a spinning machine and a winder are connected to each other, the peg tray may be clogged due to excessive supply of the peg tray from the winder or malfunction of the driving means. When the transfer means is moved forward in this state, an unreasonable force is applied to the guide member and the drive device of the transfer means that constitute the transfer path, which may lead to deformation and damage of the guide member and the restriction member. Further, if the operator operates the pipe changing device without noticing the abnormality of the stop position of the peg tray, there is a possibility of causing a large trouble such as a large breakage of the bobbin holding device.

As a device for solving this problem, Japanese Unexamined Patent Publication No. 64-85333 discloses a guide member which constitutes a transfer path of a peg tray having a length three times or more the diameter of the peg tray. It has been proposed to provide an opening that opens the path to the side and an opening / closing member that covers the opening so as to open when a force of a predetermined amount or more is applied. In this device, if the transfer means is moved forward while the movement of the peg tray is blocked for some reason, such as the accumulation of cotton wool, a force greater than a predetermined force acts on the opening / closing member to open the opening / closing member. Then, the peg tray pops out of the transfer path through the opening, so that an unnecessary force is not applied to the guide member and the transfer means, which prevents the guide member and the like from being deformed or damaged. Further, by providing a sensor that detects that the opening / closing member is opened, it is possible to detect the occurrence of an abnormal situation.

[0006]

[Problems to be solved by the device]

 In the device disclosed in Japanese Patent Laid-Open No. 64-85333, the peg tray comes out of the transfer route in the event of an abnormality, so that the operator takes measures against the abnormal cause such as the bobbin not being properly attached or the cotton wool being clogged. After that, it is necessary to return the peg tray that has jumped out of the transfer path to its original position before restarting the drive of the transfer device. However, in order to return the peg tray to its original position, a large number of peg trays that are in continuous contact with each other upstream of the opening where the peg tray pops out are manually moved sequentially and popped out. It is necessary to form a space for the bag tray, which is troublesome. In addition, if the peg tray with the full bobbin pops out, the bobbin may fall down and the thread may become dirty.

The present invention has been made in view of the above-described problems, and an object thereof is to be able to immediately detect when a peg tray is clogged during conveyance of the peg tray for some reason. It is to provide a peg tray transfer device.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a guide member for movably guiding a peg tray having a peg for mounting a bobbin on a top surface in a row, and a reciprocating drive along the guide member and a forward movement. In a peg tray transfer device equipped with a transfer means for sometimes engaging with the peg tray and transferring the peg tray at a predetermined pitch, the peg tray transport device engages with the peg tray when the transfer means moves forward and moves to the rear of the peg tray. A detection device for detecting the deformation of the guide member is provided in front of the restriction member that blocks the relative movement of the guide member.

According to the second aspect of the invention, the guide member is divided into a plurality of parts, and a detection device for detecting the deformation of the guide member is provided for each guide member.

[0010]

[Action]

 In this apparatus, the peg tray is transferred by a predetermined amount in the forward direction of the transfer means by the reciprocating movement of the transfer means. If the transfer means is moved forward while the movement of the peg tray is blocked for some reason, such as the accumulation of cotton wool on the transfer route of the peg tray, the centers of the consecutive peg trays in contact with each other are A large force acts on the guide member from the peg tray due to displacement in the width direction of the transfer path. When the guide member is deformed by this force, the detection device immediately detects the deformation.

In addition, in the device according to the second aspect, when the peg tray is clogged, the guide member in which the peg tray is clogged is detected from among the detection devices provided in the plurality of divided guide members. A detection device on the upstream side detects the deformation of the guide member.

[0012]

Embodiment 1 Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. As shown in FIG. 3, peg tray transfer devices T1 and T2 are arranged on both left and right sides of the spinning machine base 1 along the machine longitudinal direction. An empty bobbin carry-in conveyor 2 is connected to one end of one peg tray transfer device T1, and a full bobbin carry-out conveyor 3 is connected to one end of the other peg tray transfer device T2. The winder process ( Full bobbin and empty bobbin are transported and supplied to and from each other (not shown). .

The peg tray transfer devices T1 and T1 are configured to be capable of mounting the peg trays 4 in a single row, and to be reciprocally movable along a spindle row (not shown). The transfer rail 5, a guide cover 6 as a guide member for suppressing lateral displacement of the peg tray 4 mounted on the transfer rail 5 from the moving direction of the transfer rail 5, and the forward movement of the transfer rail 5 of the peg tray 4. A positioning member 7 (shown in FIGS. 4 (a) and 4 (b)) that allows the movement to the side and regulates the movement to the backward movement side is provided. The peg tray 4 has a peg 4a on which a bobbin is mounted on the upper surface and a locking recess 4b on the lower surface.

Inside the guide cover 6, the transfer rail 5 engages with the guide groove 9a formed on the upper surface of the bracket 9 and the support bracket 10 (shown in FIGS. 4 (a) and 4 (b)). It is supported so that it can move back and forth along the line. The transfer rail 5 is connected to a piston rod of an air cylinder arranged at the end of the spinning frame 1 via a connecting member (none of which is shown), and the spindle is moved along the spindle row by the operation of the air cylinder. It is designed to reciprocate integrally with a stroke slightly larger than the pitch.

As shown in FIGS. 3 and 5 (a), the rear end of the transfer rail 5 arranged on the L side of the spinning frame 1 (gear end GE side) is engaged with the outer peripheral surface of the peg tray 4. At the same time, a regulation plate 11 is fixed as a regulation member that prevents relative movement of the peg tray 4 to the rear when the transfer rail 5 moves forward. Further, a feed pawl 12 as a regulating member is attached to the rear end of the transfer rail 5 arranged on the R side (out end OE side) so as to be movable integrally. As shown in FIG. 5B, the feed claw 12 is rotatably supported by a support member 13 fixed between a pair of transfer rails 5 via a shaft 14, and one end of the feed claw 12 is fixed by a leaf spring 15. It is urged to rotate upward from the upper surface of the transfer rail 5, that is, in a state in which it can project into the locking recess 4b of the peg tray 4.

The positioning member 7 is disposed inside the transfer rail 5 in a state of extending along the longitudinal direction of the transfer rail 5, and can be engaged with the locking recess 4b as shown in FIG. 4A. A plurality of locking protrusions 7a are formed in a saw-tooth shape at the same intervals as the spindle pitch. Then, each locking projection 7a is supported by a leaf spring 16 so as to be movable up and down so that each locking projection 7a can be arranged so as to penetrate into the locking recess 4b at a position corresponding to the spindle. The plate bar 16 has one end fixed to the support bracket 10 and the other end fixed to the side surface of the end portion of the positioning member 7. Further, the positioning member 7 is arranged so that the peg tray 4 is arranged at the pipe replacement position corresponding to the spindle with all the locking projections 7a in contact with the locking recesses 4b.

As shown in FIG. 3, one end of the guide cover 6 is extended to the vicinity of the empty bobbin carry-in conveyor 2 or the full bobbin carry-out conveyor 3 and a direction changing rail 8 is provided at the other end. Are connected to each other via. A feeder 17 is arranged near the connecting portion between the transfer rail 5 and the direction changing rail 8 arranged on the R side of the spinning frame 1. The feeding device 17 engages with the peg tray 4 arranged at the end of the peg tray transport device T1 to feed the peg tray 4 onto the direction changing rail 8, and an air cylinder that rotates the feed lever 18. 19 and a regulation lever 20 that regulates so that when the feed lever 18 feeds the peg tray 4 on the peg tray transport device T1 to the direction changing rail 8, the following peg tray 4 does not hinder the feeding work. I have it. The regulation lever 20 is rotatably supported by the tip of the feed lever 18, and the rotation of the counterclockwise direction in FIG. 3 is regulated by the action of the pressing device 21 mounted on the feed lever 18. ing.

The guide cover 6 is divided into a plurality of pieces, and each guide cover 6 is formed to have a length corresponding to 20 to 30 peg trays 4. The guide cover 6 is fixed to the bracket 9 and the support bracket 10 via bolts 22 (shown in FIG. 4B) so as to extend in parallel with the transfer rail 5. As shown in FIG. 1, a strain gauge 23 constituting a detection device for detecting the deformation of the guide cover 6 is attached to one of the paired guide covers 6. Each strain gauge 23 (only one is shown) is electrically connected to the control device 25 via a signal line 24. The control device 25 is electrically connected to an abnormality display device 26 that informs the operator of the abnormality. Then, the control device 25 inputs the output signal of the strain gauge 23, judges whether or not the guide cover 6 is deformed based on the signal, and when it is judged that the deformation is generated, the drive signal is sent to the abnormality display device 26. And an operation stop signal is output to the air cylinder that reciprocally drives the transfer rail 5.

Next, the operation of the apparatus configured as described above will be described. When the spinning machine base 1 is fully stopped and the pipe changing work by the pipe changing device is completed, the full bobbin can be carried out and the empty bobbin can be supplied. When the winder issues a full bobbin request signal, the full bobbin is unloaded from the spinning frame 1 and the empty bobbin is loaded into the spinning frame 1.

The operation of the air cylinder causes the transfer rail 5 to reciprocate with a stroke slightly larger than the spindle pitch. During the forward movement of the transfer rail 5, the peg tray 4 on the transfer rail 5 moves together with the transfer rail 5, and the bottom surface of the peg tray 4 engages with the upper surface of the locking projection 7a of the positioning member 7 during the movement. When the transfer rail 5 further advances in this state, the peg tray 4 moves the positioning member 7 downward against the force of the leaf spring 16 and passes above it, and is transferred by the amount of forward movement of the transfer rail 5.

The peg tray 4 is reliably transferred by the forward movement of the transfer rail 5 when the transfer rail 5 is moved forward by the action of the regulation plate 11 or the feed claw 12 attached to the rear end of the transfer rail 5. When the advancement of the transfer rail 5 is completed, the locking protrusion 7a of the positioning member 7 penetrates into the locking recess 4b of the peg tray 4, and a gap is generated between the locking recess 4b and the locking protrusion 7a. Placed in a state. When the transfer rail 4 is returned, the locking projections 7a protruding into the locking recesses 4b of the peg tray 4 are engaged with the locking recesses 4b to prevent the peg tray 4 from retracting, and each peg tray 4 corresponds to a spindle. It is placed at the designated pipe replacement position.

By one reciprocating movement of the transfer rail 5, the peg trays 4 on the transfer rails 5 of the peg tray transfer devices T1 and T2 are moved forward by about the spindle pitch, and the peg tray 4 on the transfer rails 5 of the peg tray transfer device T2 is moved. The peg trays 4 are fed one by one onto the full bobbin carry-out conveyor 3, and the peg trays 4 are supplied one by one from the empty bobbin carry-in conveyor 2 onto the transfer rails 5 of the peg tray transfer device T1. Further, by the operation of the feeding device 17, the peg trays 4 on the peg tray transport device T1 are fed one by one onto the direction changing rail 8 and the peg trays 4 on the direction changing rail 8 are fed one by one onto the peg tray carrying device T2. Be done.

When the peg tray 4 is being smoothly transferred, as shown in FIG. 2A, the peg tray 4 moves on a substantially straight line, and the force applied from the peg tray 4 to the guide cover 6 is very small. The cover 6 will not be deformed.

On the other hand, if a large amount of cotton wool is accumulated on the transfer path of the peg tray, or if the transfer rail 5 is moved forward without the bobbin being properly attached to the peg tray, the bobbin will become part of the machine base. When the transfer rail 5 moves forward, the peg tray 4 may not be able to move as a whole due to being caught or pinched between the guide cover 6 and the peg tray 4 in a lump. When the transfer rail 5 is moved forward by the operation of the air cylinder in this state, the peg tray 4 on the transfer rail 5 moves laterally as shown in FIG. 2B. Then, the component of the force acting in the longitudinal direction of the transfer rail 5 on the peg tray 4 via the regulation plate 11 or the feed pawl 12 acts on the guide cover 6, and the guide cover 6 is deformed.

When the guide cover 6 is deformed, the strain gauge 23 outputs a signal corresponding to the deformation to the control device 25. Then, the control device 25 confirms that the guide cover 6 is deformed by the output signal from the strain gauge 23, outputs a drive signal to the abnormality display device 26, and outputs an operation stop signal to the air cylinder that drives the transfer rail 5. Is output. As a result, the application of excessive force to the guide cover 6 and the drive device is stopped. Further, the operator can immediately know the occurrence of the abnormal situation by checking the abnormality display device 26. Then, after the operator removes the cause of the clogging of the peg tray 4, the transfer of the peg tray 4 is restarted. Unlike the conventional device in which the peg tray is pushed out of the transfer path to prevent an unreasonable force from being applied to the guide cover or the like, the peg tray transport devices T1 and T2 can be driven immediately after the cause of the clogging is removed.

Since all the peg trays 4 do not apply a lateral force only to the guide covers 6 on one side, even if the strain gauges 23 are attached to only one side of the pair of guide covers 6, When the peg tray 4 is clogged, the guide cover 6 to which the strain gauges 23 are attached is always deformed, so that the clog of the peg tray 4 is accurately detected.

Further, since the guide cover 6 is divided into a plurality of pieces and the strain gauge 23 is attached to each guide cover 6, when the peg tray 4 is clogged, the clogged guide cover 6 is generated. Also, a deformation detection signal is output from the strain gauge 23 attached to the guide cover 6 arranged upstream thereof. Therefore, it is possible to immediately detect the deformation of the guide cover 6 at any position where the clogging of the peg tray 4 occurs, and it is possible to identify the location of the occurrence. Then, the operator does not need to inspect the entire peg tray transporting devices T1 and T2, and inspects the portion of the guide cover 6 corresponding to the most downstream strain gauge 23 of the strain gauge 23 that outputs the deformation signal. Just rubbing will improve.

Second Embodiment Next, a second embodiment will be described with reference to FIGS. 6 and 7. This embodiment differs from the previous embodiment in that a proximity switch 27 is used instead of the strain gauge 23 as a detection device for detecting the deformation of the guide cover 6. The proximity switch 27 is disposed at a position corresponding to the lower inside of the guide cover 6 as shown in FIG. 6, and the distance between the proximity switch 27 and the guide cover 6 is the ON area of the proximity switch 27 as shown by the solid line in FIG. The limit value t1 is set to be t1. That is, in the normal state, the proximity switch 27 is held in the ON state. When the peg tray 4 is clogged during the operation of the peg tray transport devices T1 and T2, and the transfer rail 5 is moved forward and the guide cover 6 is deformed in that state, the proximity switch 27 and the guide cover 6 are moved as shown by a chain line in FIG. The distance between and increases from the limit value t1 of the ON area of the proximity switch 27 to the value t2 of the OFF area, and the proximity switch 27 is turned off. When the proximity switch 27 is turned off, the control device 25 outputs a drive signal to the abnormality display device 26 and an operation stop signal to the air cylinder that drives the transfer rail 5.

The present invention is not limited to the above-mentioned embodiments, and for example, the guide cover 6 may be provided without being divided into a plurality of parts. Further, it may be applied to an apparatus similar to that disclosed in JP-A-57-161133.

It is possible to take action. In addition, the operation of the peg tray transfer device can be started in a short time after the treatment for the cause of the clogging of the peg tray is completed.

In addition, in the device according to the second aspect, the guide member is divided into a plurality of parts, and a detection device for detecting the deformation of each guide member is provided.
