Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tube conveyance system in an automatic winder.

The tube yarn wound and doffed by the spinning machine is rewound in an automatic winder in order to remove yarn defects or to obtain a package with a size and shape suitable for subsequent processes.

In such an automatic winder, one automatic winder is constructed by arranging multiple winding units in parallel, and in each of the winding units, each unit pulls out the yarn from the tube yarn and is rotated by a drive drum. The thread is wound around the package, and each unit is equipped with a slab catcher, a tensioning device, a waxing device, etc. to detect and remove thread defects. There are cases where a single Notsuta is running.

In any case, the same type of pipe thread is wound back by such an automatic winder at the same time for one winder.

In other words, when rewinding multiple types of yarn with different counts, colors, etc., either (a) install multiple winders and rewind one type of yarn with each winder, or (b) use one winder to rewind one type of yarn. When a winder handles many types of yarn, after winding one particular type of yarn is completed, another type of yarn is wound. In other words, the former (a) is a space consumption type,
The latter (b) is the time-consuming type.

However, any type of winding method is unproductive when rewinding small quantities of a wide variety of pipe yarns.

Therefore, the applicant first divides one winder into a plurality of sections, supplies different types of yarn to each section, and simultaneously rewinds multiple types of yarn with one automatic winder. An application was filed for a new system (Japanese Patent Application No. 57-36197), but in this case, a dedicated pipe entry and return path was provided for each type of pipe yarn, so the conveyor space for transporting the pipe yarn was increased by the number of different types. As a result, the space for the conveyance path becomes larger than the installation space for the automatic winder itself, and if the installation area of the factory is limited, the number of winders that can be installed is limited. Further, it is extremely troublesome to increase or decrease the number of winding units in one section, and it is almost impossible to modify the conveyance path.

The present invention provides a yarn conveying system that can solve the above problems.

Embodiments of the present invention will be described below with reference to the drawings.

In the embodiment shown in Figures 1 to 3, different types of yarn are conveyed by trays of different colors, and the color of the trays is detected to supply the yarn of a predetermined type to each winding section. , Therefore, the pipe thread inlet path common to each pipe thread is provided extending along all the winding sections, and the trays are sorted by gates provided at the intake ports of each winding section.

That is, in FIG. 1, when one automatic winder winds three types of yarn, it is substantially divided into three winding sections 101, 102, 103,
Each winding section 10 is on one side of the automatic winder.
1, 102, and 103, and a thread entry path 104 dedicated to each section, 105, 106,
107 is formed, and the sections 101 and 102 are sorted by movable gates 108 and 109 into the yarns of this section and the yarns of other sections, and are supplied to a carry-in path dedicated to the winding section.

On the other hand, on the other side of the automatic winder, a return path 110 for trays discharged from each section is formed by a common conveyor.
A return path 111 that supplies the yarn with residual yarn to the pick-up device again, and a return path 11 that returns the empty bobbin to the spinning machine.
2 by a movable gate 113.

Further, one end of the automatic winder is provided with a single pulling device 114 for pulling out the yarn ends of all pipe yarns regardless of the type.
A pipe yarn supply path 115 having a yarn layer and a delivery path 116 for sending out the pipe yarn that has been completely drawn out are connected to the pipe.

A storage section 117 is provided between the delivery path 116 and the yarn inlet path 104 to temporarily store the yarn that has been taken out.

That is, in FIG. 2, pipe yarns A of different types,
B and C are inserted into trays X, Y, and Z of different colors, for example, blue, black, and white, and the output device 114
The tray sent out from the mark sensor 118,1
19, and are sorted and stored in the tray storage sections 120, 121, and 122 of each color in the storage section 117.

For example, when a blue tray passes through the delivery path 116, only the mark sensor 113 for detecting the blue tray is activated, and the movable gate 124 turns from the solid line position to the two-dot chain line position 124a via the control unit 123 such as a relay or cylinder. The blue tray X is the storage part 12
0 automatically.

In addition, in the case of black tray Y, the mark sensor 119 for detecting the black tray is activated, and the movable gate 1
Since the movable gate 124 is in the solid line position, the black tray Y is automatically transferred to the storage path 121.

Reference numerals 126, 127, and 128 are movable gates that are opened and closed by a gate control signal from a counter unit 129, which will be described later.Each gate is normally located at the solid line position, and one gate opens in response to a specified tray supply command, and a specified tray is carried in. 104. A sensor 130 for detecting the number of trays to be supplied is provided in the carry-in path 104, and a tray detection signal from the sensor is input to the counter unit 129.

Further, movable gates 108 and 109 are provided at each section position of the carry-in path 104, and when mark sensors 131 and 132 immediately before the gates detect a tray of a predetermined color, the gate is activated to move the carry-in path 104 through the control unit. For example, when the sensor 131 in FIG.
It is supplied to the carry-in path 105 of No. 1.

On the other hand, in a part of the return path 110, mark sensors 133, 134, and 135 for detecting the color and number of trays discharged and conveyed from the winding unit, and a counter unit 129 for counting and controlling signals from the mark sensors are arranged. be done.

That is, in the case of this embodiment, sensor 133 is a sensor for detecting a blue tray, sensor 134 is a sensor for detecting a black tray, and 135 is a photoelectric mark sensor for detecting a white tray.

Each time a tray of a detectable color passes, each sensor 133, 134, 135 sends a subtraction signal to the counter control unit 129, causing the scales of the count display panels 136, 137, 138 for each color to be subtracted.

After a certain period of time, a gate signal is sent from the control unit to supply the trays of each storage path to the carry-in path 104, and trays of the same color as the counter value is decremented are supplied.

Note that 139 is a remaining yarn detection sensor, which detects whether or not yarn still remains on the tray discharged from each winding section, and a photoelectric sensor is used.

If more than a predetermined amount of thread remains, the sensor 13
9 is sensed and activated, and the gate 1 is activated via the control unit 140.
13 is turned from the solid line position to the two-dot chain line position 113a, and the tray 34 is transferred to the return path 111 to be supplied to the pick-out device 114 again.

In the case of an empty bobbin with no yarn remaining, the gate 113 continues to hold the solid line position, and the tray of empty bobbins is transferred to the spinning machine or other process via the return path 112.

141 is a guide that has guide curved surfaces 142 and 143 and is swingable within a certain angle around a fixed shaft 144. The guide swings between stoppers 145 and 146 due to the pressing force of the tray, and moves the tray with the remaining yarn in the return path. 34 and the newly transported tray 34a are transferred to the feeder 114.

The winding unit 19 is connected to the yarn introduction path 105, 10.
6,107 and the return path 110.

In FIG. 3, reference numeral 65 denotes a rotating disk for transporting the yarn on the yarn inlet path 9 to the winding position 66 and discharging the empty bobbin 67, which has been wound up at the winding position 66, to the return path. , its surface is inclined with respect to the horizontal, and the yarn introduction path 9 side is higher than the return path 12 side.

Guide plates 68 and 69 are provided above the rotating disk 65 at a constant distance from the rotating disk 65.

The guide plates 68 and 69 form a yarn intake port 70 and a yarn discharge port 71 between the guide plates 68 and the guide plate 8, and a yarn waiting groove 72 and a yarn discharge groove 73 are formed between the guide plates 68 and 69. do.

The connection position between the yarn waiting groove 72 and the yarn discharge groove 73 is the winding-up position 66.

74 is a lever for discharging an empty bobbin that has been wound up. A pressure air injection nozzle 76 connected to a conduit 75 is provided below the tray 34 at the roll-up position 66 to a pressure air source (not shown).

The pressurized air injected from the pressurized air injection nozzle 76 is ejected from the peg 39 of the tray 34 into the wood pipe, and blows up the thread ends hanging down from the top of the wood pipe into the wood pipe.

Above the yarn tube 33 at the winding position 66, there are a balloon breaker 77, a relay pipe 78 that guides the yarn end of the yarn tube to a knotter (not shown), a package (not shown), a relay pipe (not shown) that guides the end of the package yarn to the knotter, and a yarn detection device. and so on.

The operation of such a device will now be explained.

For example, in Figure 1, the winding section 10
1, 102, and 103, if 4 blue trays
Although the order on 10 may be random, the trays that support empty bobbins are transported along the return path 110 in the direction of the arrow, passing sequentially in front of the sensors 133, 134, and 135 in FIG. 112, the tray supporting the bobbin with remaining yarn activates the detection switch 139, the gate 113 rotates and moves to the position 113a indicated by the two-dot chain line, and the tray supports the bobbin with the remaining yarn.
4 on the return path 111.

When each tray passes in front of the sensors 133, 134, and 135, the sensor 133 detects only the number of blue trays X, and sends a signal to the counter control unit so that the value on the display panel 136 decreases by 4 from the set value. .

Similarly, the sensor 134 detects only the black tray Y, and the value on the display panel 137 decreases by 3, and the sensor 135 detects only the white tray Z, and the value on the display panel 137 decreases by 3.
The value of 8 decreases by 2.

Subsequently, from the counter control unit 129,
When a tray supply signal to the storage section 117 is issued, for example, a white tray supply signal is first issued, the gate 128 of the storage path 122 is moved to the chain double-dashed line position 128a by a known actuation means such as a relay or solenoid.
Move to.

Therefore, the first 11 white trays Z are sent out onto the carry-in path 104 and transported in the direction of the arrow. When the tray Z1 is delivered, the gate 128 closes, and the next tray Z2 passes through the gate 128 by opening the stopper 147 or sinking from the lower surface of the passage.
reach the position.

Gate 128 and stopper 147 can also be interlocked.

When the first tray Z1 is transferred in the direction of arrow 148 and passes in front of the sensor 130, a signal indicating that one tray has passed is sent to the counter unit 129 and the value on the display panel 138 for the white tray is incremented by 1. However, since the set value has not yet been reached, the white tray supply signal is further output, the gate 138 is opened, and the next white tray Z2 is sent to the carry-in path 104.

Similarly, the sensor 130 detects the passage of one tray and adds 1 to the value on the display panel 13 for the white tray of the counter control unit 129, so that the value on the display panel becomes the set value, and the supply of the white tray is completed. do.

Subsequently, the counter control unit 129 outputs a black tray supply signal in the same manner as described above, and three black trays Y are sent to the carry-in path 104, and further four blue trays X are sent out.

Therefore, the same type and the same number of trays as the trays discharged from each section 101, 102, 103 of the winder are supplied to the carry-in path 104, and are transported on the carry-in path 104 in the direction of arrow 148.

The sensors 131 and 132 provided on the entrance side of each section of the carry-in path 104 are mark sensors for detecting blue trays and black trays, so even if a white tray passes through the sensors 131 and 132, the sensors 13
1,132 is inoperative and therefore gate 108,1
09 maintains the first state, the white tray reaches the intake passage 149 of section 103, and the passage 1
49 to section 103 dedicated pipe/thread entry path 1
07, and is supplied to the standby groove 72 of the winding unit from which the empty bobbin or the bobbin with residual yarn in the section 103 was discharged, in the same manner as described in the previous embodiment.

On the other hand, the following black tray is transported on the carry-in path 104, and when it passes the position of the black tray detection sensor 132, the sensor acts, and the gate 109 pivots to close the carry-in path 104, and the section 102
The three black trays are automatically fed into the dedicated input path 106 of the section 102 and fed to the desired take-up unit.

Similarly for the blue tray, section 1
01 is supplied to a predetermined winding unit.

In this way, the same number of new trays as the total amount of trays discharged from the winder are supplied to the winder, and the same number of new tube yarns as the number discharged from the winder are also supplied to the predetermined winding unit. One winder can wind different types of yarn, and one winding unit can wind multiple types of yarn without the risk of winding different types of yarn. Even when the yarn is returned to obtain a single package, stable and efficient winding can be performed without contaminating the package with threads of other types.

Although the above embodiment shows a method of winding three types of yarn with one winder, it is also possible to wind two, four, or five or more types of yarn using the same method as described above. In this case, the number of storage channels in the storage section, the number of intake passages for dividing the winder into a predetermined number of sections, the number of mark sensors, etc. need to be set in accordance with the number of products.

As described above, in the present invention, one winder having a large number of winding units arranged side by side is divided into sections each having a plurality of units, and a different type of yarn is supplied to each section for winding. As a result, multiple types of yarn can be wound with one winder, the winder can be used flexibly, and operating efficiency can be improved.
The drive source for the blower, the drive source for the tube transport device, etc. need only be provided at one end of the winder, and the space can be used effectively.

Furthermore, a common pick-up device for different types of yarns and a common conveyance path are formed between each winding section, and a specific type of yarn is conveyed to a specific section via the yarn intake passage. Therefore, it is possible to save space on the conveyance path, and it is also easy to cope with the increase or decrease in the number of winding units constituting one section.
