Description

System of Conveying Spun Thread and Doffing Device

The present invention relates to a system for carrying the spun cone from a winding machine and a doping device for use in the system.

In spinning mills, several winding machines are usually arranged in parallel. Each winding machine is provided with a number of winding units for winding the yarn into a cone. Each winding machine has a first conveyor for conveying cones discharged from the winding unit. The first conveyor is installed to extend in the longitudinal direction of the winding machine. At the distal end of the first conveyor, a device called a doping device or a doffer is installed. The second conveyor is installed to receive and transport the cone from each doping apparatus located on one side of the winding machine. That is, the cone of the yarn wound in the winding unit of the winding machine is delivered to the first conveyor, the doping apparatus receives the yarn from the first conveyor and transfers it to the second conveyor. The second conveyor transfers the spun cones produced in the spinning factory to the packing position. The second conveyor is usually located at a higher position than the winding machine.

The transport system of the yarn of the prior art as described above is as follows. First, each wound yarn cone of the winding machine is placed on the first conveyor. When the number of cones on the first conveyor reaches a certain number (for example 25), the conveyor carries the cones. When the cone reaches the position of the doping apparatus, the doping apparatus receives the cones one by one and raises them vertically. At this time, the orientation of the spun yarn may be switched in accordance with the structure of the second conveyor. The doping apparatus raises the cone and transfers it to the second conveyor.

This conventional conveying system only transfers all the cones (for example, 25) delivered from one winding machine to a certain position at the end of which the winding machines are arranged in the factory. I can deliver it. This is to prevent the spinning yarn cones delivered from each winding machine in the second conveyor to overlap. Therefore, if the doping device on one of the winding machines carries the cone to the second conveyor, even after the other number of winding machines have already taken a certain number (25) of cones and transported them to the first conveyor, the second conveyor Can't deliver to. Therefore, the other winding machine cannot deliver the cone wrapped in the winding unit to the first conveyor until it is time to deliver its cone to the second conveyor. Therefore, the time when the winding machine does not operate is made, and the efficiency falls.

In order to solve this problem, the speed of the second conveyor can be increased. However, when the second conveyor moves at a high speed, even a slight change in speed occurs, or when the second conveyor stops to receive the cone from the doping apparatus, friction occurs between the spinning yarn wound on the cone and the conveyor. Due to this friction, the yarn wound on the cone is likely to be defective, such as fluff.

Meanwhile, the doping apparatus receives the cones one by one and passes them to the second conveyor, thereby decreasing efficiency. Moreover, the structure is complicated by using a plurality of motors or chains to vertically raise the cone and change the orientation.

The present invention is to improve the above problems, it is an object of the present invention to provide a conveying system that can carry a number of spun cones at once.

Another object of the present invention is to provide a conveying system which can lower the conveyor speed and thus reduce the defects of yarn.

Another object of the present invention is to provide a doping apparatus capable of delivering a plurality of spun cones at once.

Another object of the present invention is to provide a doping apparatus with a simple structure and a reduced number of driving apparatuses.

It is preferable that a 2nd conveying apparatus is a conveyor belt. On the downstream side of the second transfer device 22, a packaging station 23 is located. The packing station 23 is equipped with a packing machine 24. A third transfer device 29 is installed to carry the packing box. An inspection station and a shipping station are arranged around the third transfer device 29. A control device (not shown) for controlling the devices is provided in the spinning mill. The control device controls the movement of the wound cone, as will be described later.

2 and 3, the doping apparatus 15 includes a support 52, a lifting device 54, a driving device 55, a supporting device 59, and a support 60. The strut 52 is a hollow cylinder. The lifting device 54 moves up and down in the support 52. The support device 59 is fixed to the upper portion of the elevating device 54. The support 60 is mounted on the support device 59. The lifting device 54 is driven by the driving device 59. In FIG. 2 and FIG. 3, the base 60 shows only a cut part.

The strut 52 has a base 62 and a body 64 fixed to the bottom of the factory. The cylindrical body 64 is fixed to the base 62. The guide groove 66 is formed in the body 64. Guide groove 66 is composed of a lower straight portion 69, the middle curved portion 72, the upper straight portion 74. The curved portion 72 extends in the longitudinal direction while rotating at an angle (90 degrees in the preferred embodiment) in the circumferential direction of the body 64 of the strut 52. The strut 52 has a flange 75 located at the top. The flange 75 extends radially outward from the top surface of the strut 52. The flange 75 has an arcuate groove 76. Inside the upper portion of the support 52, there is a guide bush 79 for guiding the up and down of the elevating device. In the embodiment of Figure 2, the guide groove is exposed to the outside, it may be installed on the inner surface of the support (52).

Referring to Figure 3, the lifting device 54 is made up of a long hollow cylinder. The lifting device 54 is accommodated inside the strut 52 and moves up and down. The elevating device 54 has a guide flange 82 dimensioned to be able to slide inside the strut 52 at its lower end. The guide flange 82 has a projection 84 that projects radially outward. The protrusion 84 is accommodated in the guide groove 66 of the strut 52 so that the movement trajectory is constrained by the guide groove 66. In the embodiment of Figure 2, the guide groove is installed in the support and the projection is installed in the lifting device, alternatively, the guide groove may be installed in the lifting device and the projection may be installed in the support.

The drive device 55 is composed of a cylinder 85 and a piston 86. The lower portion of the cylinder 85 is fixed to the base 62 of the strut 52. The inside of the cylinder 85 is connected to the outside of the strut 52 by a tube (not shown). Therefore, hydraulic or pneumatic pressure can be applied to the cylinder 85. The upper portion of the piston 86 is engaged with the upper portion of the elevator 54. A bearing 90 is fitted between the piston 86 and the lifting device 54. Therefore, while the piston 86 pushes up the elevator 54, the elevator 54 can rotate in the circumferential direction without being restrained by the piston 86.

2 and 3, a support device 59 is attached to the top of the elevating device 54. As shown in FIG. The support device 59 has a lower support 92, an upper support 94, a hinge 95, and a weight 99. The lower support 92 is composed of a lower plate 101 having a width and a length, and side walls 103 bent at both ends in the lower plate width direction (see FIG. 5). The lower plate 101 is coupled to the upper portion of the elevating device 54 by suitable coupling means such as bolt nut coupling, for example. The lower support 92 has a first end 105 and a second end 109. The distance from the longitudinal first end 105 of the lower support 92 to the center of the elevator 54 is longer than the distance from the second end 109 of the lower support 92 to the center of the elevator 54. . The second end 109 preferably does not protrude radially outward of the elevator apparatus.

The upper support 94 is composed of a top plate 106 having a width and a length and side walls 107 bent both sides of the top plate downward (see FIG. 5). The upper support 94 has a first end 112 and a second end 109. A hinge 95 is coupled between the first end 112 and the first end 105 of the lower support 92. The upper support 94 is rotatable about the hinge 95. The upper support 94 extends beyond the second end 109 of the lower support 92. The weight 99 hangs near the second end 114 of the upper support 94. Accordingly, the weight 99 allows the upper support 94 to be horizontal as shown in FIGS. 2 and 3. In other words, the support device 59 is kept in a folded state. The weight of the weight 99 depends on the number of spun cones on the support 60 installed on the upper support 94, and the distance between the weight 99 and the hinge 95 of the support device 59. The balance is normally maintained by the weight 99, but a stopper is provided to prevent the upper support 94 from rotating by a predetermined angle or the like due to an external impact. The stopper consists of a string 96 connected to one side of the lower support 95 and the upper support 94 (see Figure 2). In addition to the strap, you can also use the lever. In another embodiment of the present invention, the lower support 92 and the upper support 94 may be formed of a thick plate rather than a structure having a plate and sidewalls.

3, 4, and 5, the support 60 of the spinning yarn cone (C) is mounted on the support device (59). The base 60 is oriented such that the longitudinal direction of the base coincides with the longitudinal direction of the support device 59. The base has a first end 115 and a second end 119 (see Fig. 4). The second end 119 of the base 60 is preferably provided with a base 60 so that the second end 119 of the upper support 94 is located in substantially the same position as the second end 114 of the upper support (94). The doping device 15 is disposed to be adjacent to the downstream side of the first transfer device 14 so that the second end 119 of the support 60 can receive the yarn cone from the winding machine 12. A stop plate 136 is attached to the first end 115 of the base 60 (see FIG. 6). The base 60 is preferably attached with a sensor for detecting the number of cones supplied to the base 60.

These support rods 123, 126, 127 are aligned in parallel in the longitudinal direction of the support device (59). Both side support rods 126 and 127 are disposed at a position higher than the center support rod 123 to form a V shape as shown in FIG. A plurality of roller shafts 130 are connected between the side support rods 126 and 127 and the central support rod 123. The roller shafts 130 are parallel to each other and perpendicular to each of the supporting rods 123, 126, and 127. The roller 132 is fitted to each shaft 130.

The support plate 133 is attached to the center support rod 123 (see FIG. 5). The support plate 133 extends in the longitudinal direction of the base 60. The support plate 133 is rotatably coupled to the upper support 94 through the hinge 135 of the side. Thus, the support 60 can be inclined toward the second transport device 22 (see FIG. 8). A long rod 139 is attached to the first side support rod 126. The long rod 139 is not rotatable in the longitudinal direction of the supporting rod 126, but is attached to be able to rotate in the circumferential direction of the supporting rod 126. At the bottom of the bar 139, a stop ring 140 is installed (see Fig. 2). The length of the rod 139 is determined such that the stop ring 140 of the rod 139 abuts the flange 75 of the strut 52 when the elevator 54 has reached a position slightly lower than the highest height ( 8).

Hereinafter, the operation of the doping apparatus 15 according to the present invention will be described in order with reference to FIGS. 6, 7 and 8.

end. Loading the yarn cone (C)

Referring to Fig. 6, the lifting device 54 has reached the lowest position. The lower support 92 of the support device 59 has reached the lowest position together with the lift device 54. Since the first end 112 of the upper support 94 is coupled to the lower support 92 by the hinge 95, it reaches the lowest position together with the lower support 92. On the other hand, the second end 114 of the upper support 94, the weight 99 attached to the second end 114 is in contact with the upper surface of the support 52, it can not be lowered. Thus, the upper support 94 of the support device 59 rotates around the hinge 95 to form an inclination. Accordingly, the base 60 is inclined downward of the first end 115.

The spinning yarn cone C is transmitted from the first transfer device 14. The spun yarn C moves toward the first end 115 along the slope of the support by its own weight. At this time, the bearing 60 has a roller 132 to facilitate the movement of the cone (C). The first end 115 of the base 60 has a stop plate 136 to prevent the yarn cone from falling down past the first end 115 of the base 60. Each doping device 15 has a predetermined number, e.g., 6 spun cones C loaded on the support 60, and the sensing device recognizes this, or the spun yarns C even when a predetermined number of spun cones are not loaded. After a certain time has elapsed since the loading of the product, the transfer of the yarn cone from the first transfer device 14 to the doping device 15 is stopped.

I. Elevation of lifting device 54 and horizontal recovery of bearing 60

Referring to FIG. 7, after mounting the cone on the support 60, the lifting device 54 is driven by the drive device 55 to ascend. The support 60 is attached to the upper support 94 of the support device 59 while the lifting device 54 ascends along the lower straight portion 69 of the guide groove 66 in the support 52. It is leveled by the weight of 99).

All. Lifting of the lifting device 54 and rotation of the lifting device 54

Subsequently, when the lifting device 54 rises, the guide protrusion 84 of the lifting device 54 moves along the curved portion 72 of the guide groove 66 of the support 52. Thus, the elevating device 54 and the supporting device 59 and the support 60 attached thereon also rotate and move. At this time, the rod 139 attached to the side support rod 126 of the support 60 also rotates along the guide groove 76 of the flange 75 (see FIG. 2).

la. Lift of the lifting device 54 and inclination of the support 60

Referring to Fig. 8, the elevating device 54 rotates upward, and the guide protrusion 84 reaches the upper straight portion 74. At this time, the stop ring 140 of the rod 139 attached to the first side support rod 126 of the support 60 and the flange 75 of the support 52 come into contact with each other. Therefore, the rise of the first side support bar 126 is limited. When the elevating device 54 continues to rise, the support 60 is inclined about the hinge 135 so that the loaded yarn cone C is transferred to the second transfer device 22.

hemp. Lowering of the lifting device

6, 7 and 8, after transferring the yarn cone (C) to the second transfer device 22, the lifting device 54 is lowered. While descending, the restraint between the stop ring 140 and the flange 75 is released, and the support 60 returns to the horizontal state again. When the elevating device 54 continues to descend, the support rotates by the curved portion 72 of the guide groove 66. When the guide protrusion 84 of the elevating device 54 reaches the lower straight portion 69 of the guide groove 66, the lower portion of the weight 99 of the support device 59 touches the upper portion of the support 52. If it continues lowering, the base will rotate to incline about the hinge 95 of the support apparatus 59, and will be in the state which can load the spinning yarn cone (C).

Next, the operation of the yarn feed system of the spinning factory according to an embodiment of the present invention will be described with reference to FIG. 1.

1. Classification of Winding Machines

A plurality of winding machines 12A to 12J in a spinning mill are grouped into several groups by tying up winding machines that produce the same kind of yarn. For example, among the winding machine 12, the first winding machine 2A to the fourth winding machine 12D are the first winding machine group 150, the fifth winding machine 12E to the seventh winding machine 12G, The 2nd winding machine group 153, the 8th winding machine 12H, and the 9th winding machine 12I are classified into the 3rd winding machine group 156 and the 10th winding machine 12J is classified into the 4th winding machine group 160. . Here each group of winding machines winds the same kind of thread. And it is preferable to arrange the winding machines which belong to the same group so that they may adjoin each other. In addition, it is preferable that the order of each group of winding machines is counted from the group of winding machines on the downstream side of the second transfer device 22 and doped in that order.

2. Confirmation of transfer cycle

After classifying into a plurality of winding machine groups, after completing the transfer from the first transfer device 14 to the second transfer device through the doping device 15 for each winding machine group, until the next transfer starts. Set a time. This time may vary depending on the type of yarn being manufactured. In a preferred embodiment, the time taken for winding on the cone at one winding position and placing it on the first transfer device 14 is determined.

3. Convey yarn cones in the order of each winding machine group

First, the first conveying apparatus 14 in the winding machine of the first winding machine group 150 is operated to transfer the yarns. In a preferred embodiment of the present invention, the winding machine has 30 winding positions (winding units), and the speed of the first transfer device is 10 to 15 m / s. The spinning yarn cone C is loaded on the support 60 of the doping apparatus 15 in a loading standby state at the downstream end of the first conveying apparatus 14. The doping apparatus 60 may be loaded by a predetermined number (for example, six). The first transport device 14 carries the cone and loads it into the doping device 15. The first transfer apparatus 14 stops when the predetermined number, for example, six cones are loaded in the doping apparatus 60, or when a predetermined time elapses.

Subsequently, when the first transfer device of the winding machine belonging to the first winding machine group 150 is stopped, the doping device 15 is simultaneously driven to move the loaded yarn cone to the second transfer device 22. The second transfer device 22 stops before taking over the cone from the doffer 15 and operates again when the doper 15 starts to descend. In a preferred embodiment of the present invention, the feeding speed of the second transfer device 22 is 10 to 15 m / s. On the other hand, since the winding machines are spaced apart from each other, even if the winding machines of the same winding machine group send the cones to the second conveying device at once, the overlap of the cones in the second conveying device can be avoided. In a preferred embodiment, the distance between the winding machines is 2 m. After delivering the cone to the second transfer device, the doping device 15 returns to its position and receives the cone C from the first transfer device 14 and repeats the transfer of the cone C to the second transfer device 22. In one embodiment of the present invention, since the winding position is 30 and the doping apparatus can deliver six cones at once, repeating the driving of the doping apparatus five times will transfer all of the wound cones to the first winding machine group 150. Can be. After the transfer of the cone made in the first winding machine group 15 and the first transfer device returns to the position, the cone starts to be transferred to the first transfer device at the wound position again.

After completing the transfer of the cone of the first winding machine group 150, the second winding machine group 153, the third winding machine group 156, and the fourth winding machine group 160 are sequentially transferred to the cone.

4. Transfer of second conveying device and packing of cone

The cone delivered to the second conveying apparatus is conveyed to the packaging position 23. Since each winding machine group is transported in turn, when transferring the spun cone wound in any winding machine group, the same kind of cone arrives at the wrapping position. Pack this and carry out the following processes, including the inspection process.

The transfer system and the doping apparatus have been described above according to the preferred embodiment of the present invention, but the present invention is not limited thereto.

In the transfer system according to another embodiment of the present invention, the winding machines spaced apart from each other rather than adjacent to each other may be bundled into one winding machine group.

In addition, the object to be transferred is not limited to the yarn. Any package wound around the yarn can be transported.

In the above embodiment of the present invention is driven (tilt drive) to rotate along the guide groove when the support is raised and to be inclined by the action of the flange 75 and the stop ring 140 when reaching the final raised state, but the rotation The movement or the inclined drive may be performed by separate drive devices, for example, reduction motors.

According to the configuration of the present invention as described above, it is possible to transfer the spun cones of the spun yarn at a time and the spun cones from several winding machines at a time to the transfer device. Therefore, it is possible to reduce the time taken to transfer the yarn yarn cone, thereby reducing the waiting time for the transfer in each winding machine. In addition, since the feed speed is high, the speed of the conveyor belt carrying the yarn can be lowered, thereby reducing the failure of the yarn.

On the other hand, the doping apparatus can deliver a large number of yarn cones at once, the doping speed is fast. In addition, since the elevator is rotated at the same time as the lifting device, the number of the driving device can be reduced.
