Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a full/empty bobbin conveying device for a spinning machine such as a ring spinning machine or a ring twisting machine, and particularly for conveying full bobbins and empty bobbins mounted on a peg tray to and from a winder. The present invention relates to a full/empty bobbin conveying device suitable for various cases.

0002

BACKGROUND OF THE INVENTION In this type of spinning machine, in order to facilitate the automatic tube changing operation using a tube changing device when the tube is full, empty bobbins are supplied to the front of the spinning machine in a state corresponding to the spindle pitch. A transfer device is required to carry out the doffed full bobbin. As this type of transfer device, a conveyor device is generally used in which an endless conveyor belt is provided with protruding pegs for attaching bobbins at intervals equal to the spindle pitch or half the spindle pitch. However, this conveyor device has the disadvantage that if the conveyor belt stretches due to long-term use, the stretch will increase, causing deviations in the set peg spacing, which will impede automatic pipe changeover work.

[0003] As a transfer device for solving the above-mentioned inconvenience, Japanese Patent Application Laid-open No. 161133/1983 discloses a transfer device as shown in Figs. 5(a) and (b).
As shown in FIG. 2, a guide rail 52 is arranged around the spinning machine 51, and a peg 53 is placed on the upper surface of the guide rail 52.
The guide rail 52 is equipped with a plurality of peg trays 53 having a protruding portion a, a locking recess 53b formed on the lower surface, and a diameter equal to the pitch of the spindle 54 so as to be able to slide in contact with each other. A feeding device is disposed below which reciprocates a rod 56 equipped with a plurality of locking pawls 55 at predetermined intervals that can engage with the locking recess 53b using a cylinder 57, and the feeding device moves the peg tray 53 to the guide rail. A transport device is proposed that moves sequentially along 52.

On the other hand, at present, spinning machines generally have about 200 spindles per side, but there is also a trend toward increasing the number of spindles to multiple spindles. 200 per side
Even in the case of weights, for example, the production error of a peg tray is 0.1m.
If there are m, an error of as much as 20 mm will occur in the spacing between the pegs of the peg tray and the spindle due to the accumulation, which will hinder the pipe changing operation by the pipe changing machine. In order to eliminate the inconvenience caused by the accumulation of manufacturing errors, in the conventional device, a plurality of locking claws 55 that engage with the locking recesses 53b of the peg tray 53 are provided at predetermined intervals, and each of the locking claws 55 is connected to the guide rail 53. The upper peg trays 53 are pressed and moved in groups.

[0005] Then, the peg tray 53 with the full bobbin mounted thereon is moved by the operation of the cylinder 57 to a position corresponding to the full bobbin discharging device 58 installed at the end of the machine, and the full bobbin is extracted by the full bobbin discharging device 58. , and then transferred to a position corresponding to the empty tube supplying device 59 and the empty tube supplying device 5
After the empty bobbin is supplied to the peg 53a by 9, it is transferred and arranged again at a position corresponding to the spindle. It has also been proposed to connect the guide rail 52 directly to a conveyance path connecting a spinning frame and a winder, and to directly convey the peg tray 53 loaded with full bobbins doffed by the spinning frame 51 to the winder.

[0006]

[Problems to be Solved by the Invention] In the conventional device, when the guide rail 52 is not directly connected to the conveyance path connecting the spinning machine and the winder and forms a closed loop, the peg trays 53 are arranged in a predetermined number. Since the peg tray 53 is disposed within the guide rail 52, the peg tray 53 is transferred relatively smoothly by the operation of the cylinder 57. However, when the guide rail 52 is directly connected to the conveyance path connecting the spinning machine and the winder, the number of peg trays 53 arranged in the guide rail 52 is the same as the number of peg trays 53 that are fed from the conveyance path connecting the spinning frame and the winder. If a mistake occurs in feeding the peg trays 53 by the transfer device, more peg trays than the predetermined number may be fed into the guide rail 52, or the interval between the peg trays 53 may be 1. A situation may occur where there is more than one space left. and,
Troubles such as clogging of the peg tray 53 and hindrance to pipe changing work by the pipe changing machine occur. Therefore,
It is necessary to operate the transfer device with the peg trays 53 in contact with each other at the entrance of the transfer device, which is the connection part with the conveyance path that connects the winder. The transfer device is not necessarily sent at predetermined intervals, and drive control of the transfer device becomes complicated.

[0007] Also, this type of spinning machine usually has about 200 spindles on one side, and those called long machines have as many as 400 or about 500 spindles on one side, making them very long machines. For this purpose, a large number of intermediate frames called spring pieces are provided between the gear end and the out end, and are connected by a plurality of spindle rails and roller beams to form a machine frame. In order to simplify the assembly of the spinning machine frame in the spinning factory and to improve the assembly accuracy of the spinning machine frame, the frame body was constructed from units of a predetermined length, and the frame was assembled at the spinning machine manufacturing factory. The units are transported to a spinning factory, where each unit is connected to assemble a spinning machine frame. However, since the conventional full/empty bobbin conveying device has a length that extends along almost the entire length of the spinning machine frame,
There is also the problem that it cannot be incorporated into a unitized machine frame, and it takes time and effort to assemble it at a spinning factory.

The present invention has been made in view of the above-mentioned problems, and the object thereof is to be able to transport the peg tray regardless of the continuous state of the peg tray at the connection part with the transport path connected to the winder. A spinning machine that allows all the peg trays to be placed in their designated positions without any problem even if there are gaps between the peg trays during transport, and that can be assembled into a unit when the spinning machine stand is made into a unit. An object of the present invention is to provide a full/empty bobbin conveying device.

[0009]

[Means for Solving the Problems] In order to achieve the above object, in the present invention, peg trays having pegs for inserting bobbins on the upper surface are mounted in a line and are transported in a fixed direction, and the peg trays are transported in a direction A large number of individually driveable conveying devices are installed along the spinning machine table, each equipped with a regulating member to restrict lateral slippage from the spinning machine, and a stopper is installed at the unloading end of each conveying device to temporarily restrict the movement of the peg tray. A guide member for guiding the peg tray from the upstream conveying device to the downstream conveying device was provided between each conveying device.

0010

[Operation] In this device, each conveying device is driven independently, and the carrying-out of a peg tray with full bobbins and the carrying-in of a peg tray with empty bobbins are carried out without necessarily cooperating with each other. When carrying in peg trays with empty bobbins installed, when a predetermined number of peg trays are placed on the conveyance device located on the most downstream side, they are placed on the discharge side end of the conveyance device located on the upstream side of the conveyance device. The stopped stopper is now in a state to restrict movement of the peg tray. Then, a predetermined number of peg trays are stopped at predetermined positions in order from the conveying device disposed on the downstream side.

[0011]

[Example] (Example 1) Hereinafter, a first example embodying the present invention will be described.
An example will be described according to FIGS. 1 and 2. As shown in FIG. 2, a machine main body 2 disposed between a gear end GE and an outend OE of the spinning machine 1 is composed of a large number of units 3. Conveying devices 4 constituting full and empty bobbin transfer devices are arranged on both left and right sides of each unit 3 along the longitudinal direction of the machine. A belt conveyor 6 for transporting the peg tray 5 between the two transport devices 4 is disposed between the transport devices 4 . Also, the out-end OE of spinning machine 1
On the side, a carry-in conveyor 7a and a carry-out conveyor 7b which connect the conveyance device 4 with a conveyance path (not shown) which connects the spinning machine 1 and the winder are arranged. Further, at the out end OE, a sensor 8 for detecting the peg tray 5 carried out by the conveyor 4 is located at a position corresponding to the end of the carrying out conveyor 7b, and at the gear end GE, an empty bobbin carried on the belt conveyor 6 is installed. Sensors 9 for detecting the attached peg trays 5 are installed respectively.

The conveying device 4 is basically the same as that disclosed in Japanese Patent Application Laid-Open No. 63-275727. A guide cover 10 serving as a regulating member for regulating lateral displacement of the peg tray 5 from the transfer direction is attached to the unit 3 via a bracket (not shown), and a peg 5a is provided inside the guide cover 10 protruding from the upper surface. A pair of transfer rails 11 on which peg trays 5 can be mounted in a row are connected to the unit 3.
The bracket is supported by a roller 13 attached to the bracket and is disposed so as to be movable back and forth along the spindle row while engaging with a guide groove formed on the upper surface of the bracket. The transfer rail 11 is connected by a U-shaped connecting plate 12, and is also connected at one end to a piston rod 14a of an air cylinder 14 via a bracket 15, and is moved along the longitudinal direction of the spinning frame 1 by the operation of the air cylinder 14. The spindle is designed to reciprocate integrally with a stroke slightly larger than the spindle pitch.

On the inside of the transfer rail 11, there is a locking protrusion 1 that can be engaged with a locking recess (not shown) of the peg tray 5.
A plurality of locking members 16 formed in the shape of saw blades 6a extend along the longitudinal direction of the transfer rail 11 at the same intervals as the spindle pitch, and each of the locking protrusions 16a corresponds to a position of a spindle (not shown). It is supported so as to be movable up and down via a plate spring (not shown) so that it can be placed in the locking recess of the peg tray 5. One end of the leaf spring is fixed to a bracket that also serves as a guide member for the transfer rail 11, and the other end is fixed to the end side surface of the locking member 16. The arrangement position of the locking member 16 is set so that the peg tray 5 is placed at the pipe changing position corresponding to the spindle with all the locking protrusions 16a in contact with the locking recesses of the peg tray 5.

A guide plate 17 serving as a guide member for guiding the peg tray 5 from the upstream conveying device 4 to the downstream conveying device 4 is arranged between adjacent conveying devices 4. Further, a cylinder 18 serving as a stopper for temporarily regulating the movement of the peg tray 5 is disposed at the end of each transport device 4 on the discharge side, and a sensor 19 for detecting the peg tray 5 is disposed on the peg tray entry side. The guide cover 10 has a through hole (not shown) formed at a position corresponding to the sensor 19. Piston rod 1 of cylinder 18
8a engages with the base end of the peg 5a of the peg tray 5 to restrict its movement when placed in the protruding position, and becomes unable to engage with the peg tray 5 when placed in the retracted position.

Next, the operation of the apparatus constructed as described above will be explained. Peg tray 5 placed on each transport device 4
When the tube change operation in which the empty bobbin on the top is replaced with the full bobbin on the spindle is completed, the full bobbin can be carried out and the empty bobbin can be carried in. Then, when a full bobbin request signal is issued from the winder, each conveying device 4, belt conveyor 6, carry-in conveyor 7a, and carry-out conveyor 7b are driven, and the full bobbin is carried out from the spinning machine 1 and the spinning machine 1
Loading of empty bobbins will begin. There is no need to synchronize the operation timings of each transport device 4.

The air cylinder 14 is operated with the piston rod 18a of the cylinder 18 of each transfer device 4 placed in the retracted position, and the transfer rail 1 is moved through the bracket 15.
1 is reciprocated with a stroke slightly larger than the spindle pitch. When the transfer rail 11 moves forward, the transfer rail 11
The upper peg tray 5 moves together with the transfer rail 11,
During the movement, the bottom surface of the peg tray 5 touches the locking member 16.
It engages with the upper surface of the locking protrusion 16a. When the transfer rail 11 moves further in this state, the peg tray 5 moves the locking member 16 downward against the force of the leaf spring, passes above it, and is transferred by the forward movement of the transfer rail 11. When the forward movement of the transfer rail 11 is completed, the locking protrusion 16a of the locking member 16 enters the locking recess of the peg tray 5, and a gap is created between the locking recess and the locking protrusion 16a. be done. When the transfer rail 11 moves back, the locking protrusion 16a protruding into the locking recess of the peg tray 5 engages with the locking recess to prevent the peg tray 5 from moving backward, and each peg tray 5 is connected to a spindle and a predetermined pipe exchange. placed in position. The peg tray 5 detached from the transfer rail 11 during the return movement of the transfer rail 11 is supported by a guide plate 17 arranged between adjacent transfer devices 4, and then transferred onto the transfer rail 11 on the downstream side.

By the operation of the conveying device 4 and the belt conveyor 6, the peg trays 5 on the conveying device 4 are sequentially transferred to the downstream conveying device 4, and the peg trays 5 are transferred from the most downstream conveying device 4 onto the conveyor 7b for carrying out. It is carried out and sent out to the conveyance path to the winder via the conveyor 7b for carrying out. Further, a conveying device 4 in which a peg tray 5 with empty bobbins mounted thereon is disposed at the most upstream side via a carrying conveyor 7a.
will be handed over to. Then, a detection signal from a sensor 8 provided at the out-end OE is input to a control device (not shown), and the number of peg trays 5 carried out from the spinning machine 1 is counted. When the value reaches a value corresponding to the number of spindles of the spinning machine 1, the cylinder 18 of the conveying device 4 disposed at the most downstream is activated, the piston rod 18a protrudes to the regulating position, and the peg tray 5 from the conveying device 4 is activated. The removal of the items will be stopped. In this state, each transport device 4 continues to be driven, and when the sensor 19 of the most downstream transport device 4 detects that the peg tray 5 at the position corresponding to the sensor 19 is in a stopped state, the transport The driving of the device 4 is stopped, and the cylinder 18 of the conveying device 4 on the upstream side is activated to project the piston rod 18a to the regulating position. Thereafter, similarly, when the sensor 19 detects that the peg tray 5 at the position corresponding to the sensor 19 is in a stopped state, the driving of the transport device 4 is stopped.

[0018] Also, the sensor 9 provided at the gear end GE
Every time the peg tray 5 with an empty bobbin attached is transferred onto the belt conveyor 6, a detection signal is output to the control device, and the control device adjusts the peg tray 5 based on the signal.
When the count value reaches the number of spindles on one side of the spinning frame 1, an activation signal is output to the cylinder 18 of the conveying device 4 adjacent to the upstream side of the belt conveyor 6, and the cylinder 18 is activated to move the piston rod 18a. is projected to the regulated position. When the sensor 19 of the transport device 4 detects that the peg tray 5 at the position corresponding to the sensor 19 is in a stopped state, the drive of the transport device 4 is stopped, and the transport device 4 on the upstream side is stopped. The cylinder 18 is actuated and the piston rod 18a is projected to the restricted position. Thereafter, similarly, when the sensor 19 detects that the peg tray 5 at the position corresponding to the sensor 19 is in a stopped state, the driving of the transport device 4 is stopped. Then, the peg tray 5 with the empty bobbin attached is placed on the spinning machine 1.
are arranged at positions corresponding to the spindles.

Since each conveying device 4 is driven independently, the peg tray 5 is moved by all the conveying devices 4 when the peg tray 5 is conveyed.
There is no need for the peg trays 5 to be in contact with each other on the belt conveyor 6, and even if the peg trays 5 with empty bobbins are not continuously transported, the peg trays 5 can be sequentially transported from the most downstream transport device 4 without any problem. placed in place. Then, when the peg trays 5 are finally arranged at the predetermined positions, there are no peg trays 5 on the belt conveyor 6, and the number of peg trays 5 can be the same as the number of spindles. Furthermore, even if trouble occurs in some of the conveying devices 4, not only the downstream conveying devices 4 but also the upstream conveying devices 4 cannot carry out the conveying work unless the peg trays 5 are continuous to the concerned device. The process can be continued, and transportation time can be shortened after the problem is resolved.

Furthermore, in this embodiment, since each conveying device 4 is assembled in each unit 3, the spinning machine 1 in the spinning factory
And the assembly of the transport device 4 becomes easy. (Embodiment 2) Next, a second embodiment will be described with reference to FIGS. 4 and 5. This embodiment differs from the previous embodiment in that the conveying device 4 is constituted by a belt conveyor. That is, the belt 22 is connected between the driving pulley 20 and the driven pulley 21.
The tension is adjusted by guide rollers 23 to a predetermined tension. Drive pulley 20
is driven by a motor M, and a support plate 24 is provided inside the belt 22 to prevent the belt 22 from loosening. A guide cover 25 is disposed along the belt 22 to restrict lateral movement of the peg tray 5 that moves as the belt 22 runs. Further, as in the above embodiment, a cylinder 18 is provided at a position corresponding to the unloading end of the conveying device 4, a sensor 19 is provided at the incoming end, and a guide plate is provided between adjacent conveying devices 4. 17 are arranged. In this conveying device 4, the positioning of the peg trays placed on the belt 22 is such that the peg trays 5 are in contact with each other with respect to the leading peg tray 5 that is engaged with the piston rod 18a of the cylinder 18 and its movement is restricted. This is done by lining up. With a length corresponding to one unit of the spinning frame 1, when the peg tray 5 is placed in contact with the conveyor 4, the cumulative value of production errors of the peg tray will interfere with the pipe changing work of the pipe changing machine. It will be a value that does not occur. Therefore, the apparatus of this embodiment has a simpler configuration than the apparatus of the previous embodiment. This conveyance device 4 is also driven in the same manner as in the previous embodiment.

It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, in the transport device 4 of the first embodiment, the locking member for regulating the backflow of the peg tray 5 may be attached to the transport rail 11.
The transport device 4 may be provided only at two locations corresponding to the front and rear ends of the unit 3, or the transport device 4 may be longer than the unit 3.

[0022]

Effects of the Invention As detailed above, according to the present invention, a large number of conveying devices are driven independently, so even if there is a gap between peg trays during conveyance, there is no problem with the conveyance, and the spinning machine With the number of peg trays corresponding to the number of spindles, each peg tray can be placed in a predetermined position corresponding to the spindle, and the peg trays do not need to be in constant contact with each other at the connecting part of the conveyance path, which prevents peg trays from clogging. Problems can be prevented from occurring. Further, even if a trouble occurs in some of the conveyance devices, other conveyance devices can be driven, so that the conveyance time after the trouble is resolved can be shortened. Furthermore, when the spinning machine stand is made into a unit, it becomes possible to assemble it into the unit.
