Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for disposing of a pipe yarn that has been mis-delivered in an automatic pipe-feeding device for supplying fine spinning pipe yarn to a winder via a pick-up device.

When spun yarn is wound onto a bobbin and supplied to a winder, the yarn wound around the bobbin, that is, the tube yarn, is pulled out by a pulling device.

These processes are performed automatically and dynamically, but
Some people sometimes make mistakes when they say something. The threads that have been mis-taken are fed back to the pick-out device, but in order to do this automatically, a branch path is provided in the pipe transport path that connects the input and exit sides of the pick-out device. A circulation system for the mis-picked pipe thread is configured in which the pipe thread that has been mis-picked is guided to the branch path and automatically conveyed to the input side of the pick-out device. Through this circulatory system, threads that have been mislead are automatically re-sent to the threading device, but if for some reason they cannot be threaded, they will go around the circulation system many times, reducing the processing efficiency of the threading device. This resulted in the problem of a decline in energy consumption. Therefore, defective pipe yarns that cannot be picked out by the picking device are discharged outside the conveyance path system, and the pipe yarns are discharged to a branch path that leads to the pipe yarns that have been picked out incorrectly so that they can be intensively repaired. When a mechanism is installed and a set number of threads that have been mislead occur consecutively, or
The method of the present invention for disposing of erroneously picked-up yarns is to periodically discharge all the yarns in the branched path out of the conveying path system every time a predetermined period of time has elapsed.

Next, the method of the present invention will be explained based on an apparatus for carrying out the method. Reference numeral 1 denotes a pick-up device, and since this pick-up device 1 is no different from conventionally used devices, a description of its configuration will be omitted.

Reference numeral 2 denotes a first conveyance path for automatically supplying the pipe thread 3 spun by a spinning machine (not shown) onto a bobbin to the lead-out device 1; 4 is a pipe spun by the lead-out device 1; This is a second conveyance path for automatically supplying the yarn 3'' to a winder (not shown).

The first and second conveyance paths 2 and 4 have the same structure as the conveyance paths conventionally used in this type of device, and include a conveyor belt 5, a tray 13 which is a conveyance medium for the pipe yarn 3, and a tray. It consists of a guide plate 6 that guides the guide plate 13. 7 is a branch path, one inlet end is connected to the second conveyance path 4, the other outlet end is connected to the first conveyance path 2; , the second conveyance path, and the branch path 7 constitute a circulation system for the pipe yarn.

The branch path 7 is for automatically supplying the pipe yarn 3'' which has been mis-picked by the pick-up device 1 from the second conveyance path 4 to the first conveyance path 2 again. Taka,
Whether a mistake has been made or not is detected by a lead-out detection feeler 8 provided in the lead-out device 1, and the information of the lead-out detection feeler 8 is provided at the connection position between the second conveyance path 4 and the branch path 7. The information is transmitted to the movable gate 9, and the pipe thread 3'' of the mislead is transmitted to the movable gate 9.
When the bobbin reaches the position, the movable gate 9 blocks the second conveying path 4 and guides the pipe thread 3'' to the branching path 7. 10 is a conveying path for the empty bobbin 11. , is for automatically returning an empty bobbin 11 wound with thread by a winder (not shown) to a spinning machine (not shown), and is connected to a bobbin extraction device 12.

This bobbin extraction device 12 lifts the empty bobbins 11 carried by the tray 13 one by one and removes them from the tray 13.
This type of bobbin conveying device is for removing the bobbin from the bobbin and storing it in a hopper (not shown) or the like, and since there is no difference from conventionally used devices in this type of bobbin conveying device, a detailed explanation of the invention will be omitted. This bobbin extraction device 12 is connected to the branch path 7, so that the bobbin passing through the branch path 7 can also be extracted by electrical instruction. Reference numeral 14 denotes a half bobbin conveyance path, which is used to send so-called half bobbins, in which the yarn has not been completely wound by a winder (not shown), from the empty bobbin conveyance path 10 to the branch path 7. A movable gate 15 is provided.

Next, the method of the present invention will be explained based on the implementation apparatus.

First, a case will be described in which a situation occurs in which the thread pulling device 1 repeatedly fails to pick up the pipe yarn. Figure 2 shows the electric circuit diagram of the main parts of the device that is set to discharge all the pipe yarn in the branch path 7 out of the conveying path system when the pipe yarn is picked up incorrectly five times in a row. , the time chart is shown in FIG. Therefore, the pipe yarn 3 supplied from the first conveyance path 2 to the pick-out device 1 is picked out by the pick-out device 1. Whether the lead-out is successful or not is detected by a lead-out detection feeler 8 that operates every time the camshaft of the lead-out device 1 rotates. In FIG. 2, 21 is a switch 22 of the outlet detection feeler 8 which closes the circuit when the camshaft of the outlet device 1 operates;
3 is an instrument for detecting a successful offer, and 24 is this instrument 23
This is a switch that closes when it detects a successful offer. On the other hand, numerals 25 and 26 are switches for inputting a mislead into the counter 27. The switch 25 closes each time one thread passes through, and the switch 26 closes when a mislead is detected. 28 is a circuit for resetting the numbers input into the counter when the cue is successful.

Now, if you make a mistake in pulling out the first thread, switch 21
Since the relay 23 remains open and the switch 24 is open, the reset circuit 28'' of the counter 27 does not operate.Meanwhile, the meter 29 that detects the rotation of the camshaft is activated and the switch is activated. 26, connect the set circuit 30 together with the switch 25 that closes each pipe thread, and input the information to the counter 27.In Fig. 3, the uppermost line 3
1 represents the state of the switch 21, which forms a convex shape when the input is successful. Reference numeral 32 forms a convex shape to represent the state of the switch 25, that is, each time the pipe thread passes, and 33 forms a convex shape to represent the state of the switch 25 when an input is applied to the counter noter 27.

Now, the first pipe thread made a mistake in starting, so
The switch 21 is not activated and no convex shape appears on the line 31.
Line 32 has a convex shape because the first tube thread has passed through it, and line 3
3, a convex shape appears because the force counter 27 receives an input. The pipe yarn that has missed this lead-out is sent to the second conveyance path 4, but is sent to the branch path 7 by the movable gate 9 that operates upon detection of the mistake in lead-out and blocks the conveyance path 4. You will be guided. Next is the second tube. If you make a mistake in starting the thread, the electric circuit will have the same effect as the first thread, and the linearity of the time chart will be the same as the first thread. At this time, the tube thread is
Like the first pipe thread, it is guided to branch path 7. If the succeeding third pipe thread is successfully pulled out, the switch 21 is closed and an input is given to the meter 23, and the switch 24 is closed to connect the reset circuits 28 and 28''.
is not entered. In Figure 3, line 31 has a convex shape indicating that the third pipe thread was successfully taken out, and the counter 2
7 indicates that there was no input. At this time, the pipe yarn sent to the second conveyance path 4 is not obstructed by the movable gate 9 and advances along the conveyance path connected to the winder (not shown). If five consecutive threads from the fourth to the eighth threads are mislead, all five threads are guided to the branch path 7. In the electric circuit, there are five consecutive inputs to the counter 27 in the same way as for the first and second pipe threads, thereby closing the switch 34. 35 is a switch for detecting a tray in the bobbin extraction device 12; 36 is a time switch that is closed when the meter 37 confirms the presence of the tray; and when the switch 34 and the switch 36 are closed, the bobbin mounting motor 38 is closed. The electric circuit is connected and the bobbin is removed.

In other words, in FIG. 1, when the incorrectly picked-out tube yarn 3'' that has been guided to the branch path 7 is supplied to the position of the bobbin extraction device 12, it is all extracted and discharged to the outside of the conveyance path system. The figure shows that the line 39 representing the output of the counter 27 operates in a convex shape when five consecutive threads from the fourth to the eighth pipes miss the lead-out.The line 40 is The line 41 shows a convex shape when the presence of a tray is detected in the bobbin extractor 12, and the line 41 shows a convex shape when the bobbin extractor motor is activated.When all the pipe threads in the branching path 7 are discharged to the outside of the conveying path system, The bobbin extraction device 12 has a mis-taken thread 3.
'' is supplied, and when the yarn is not supplied to the bobbin extraction device 12 even after a predetermined period of time has elapsed, the switch 42 is opened, and this signal causes the switch 45 to open, closing the contact 43 and connecting the reset circuit 28 of the counter 27. and counter 2
Cut off the output from 7. Further, the contact 43 is set to open when the pipe thread in the branching path 7 is being discharged, and even if the lead-out is successful, the contact 43 remains open, so the contact 43 of the reset circuit 28 remains open. Counter 2
No reset signal is input to 7. In addition, in the electric circuit diagram, the switch 44 is connected to the bobbin extraction device 12.
The bobbin extractor 12 is provided in the system in which the pipe thread 3'' guided to the branching path 7 circulates, and is used to determine whether the bobbin supplied to the branch is an empty bobbin. Since it is also connected to the conveyance path 10, it is provided so that normally the yarn is circulated without being extracted, and only the empty bobbin is extracted.Next, after one hour has elapsed, A case will be explained in which all the pipe yarns are discharged out of the conveyance path system.

FIG. 4 is an electrical circuit diagram of the main parts, and FIG. 5 is a time chart. While the pick-up device 1 is in operation, the switch 51 is always on, the timer 52 is activated, and when one minute has elapsed, the timer switch 53 is turned on, the relay 54 is turned on, the switch 55 is turned on, and an input is made to the counter 56. Relay 57 turns on a little later than relay 54, opens contact 58, and cuts off the input to counter 56. As a result, a differential pulse is input to the counter 56,
By repeating this 60 times, differential pulses of 1 minute intervals are input to the counter 56 60 times. In other words, 6 gin have passed. Differential pulse is 6 on counter no. 56
When the input is 0 times, the switch 69 is turned on, and when it is confirmed that the tray is located in the bobbin extraction device 12 and the switch 58 is turned on, this signal is transmitted to the timer switch 59, and the switch 59 is turned on, and the motor is turned on. 60 electrical circuits connected 9
Then, the bobbin extraction device 12 is operated, and the bobbin yarn 3'' that has been picked out incorrectly is discharged out of the conveyance path system. When it is detected that the counter 56 does not pass, the switch 62 opens and this signal is transmitted to the swift switch 63 to connect the reset circuit of the counter 56 and cut off the output of the counter 56. In other words, when the discharged pipe 3'' disappears from the branching path 7, the one-hour measurement starts again.The flow of the pipe in FIG. 1 is the same as the first action, so it will be omitted. In Figure 5, the uppermost line 64 represents the state of the switch 51, that is, when the pick-out device is in motion, it is bent upward in the figure compared to when it is stopped, and the convex line 65 represents the generation of differential pulses every minute. The convex shape of the line 66 represents the counter 5.
The convex shape of line 67 represents the output of bobbin extractor 12.
The line 68 represents the state in which the convex shape is pulling out the pipe thread 3''.As mentioned above, the pipe thread that has been mislead is taken out again via the branch path. If the method of the present invention is applied to a device that has a conveyance path system that automatically circulates the yarn to the takeout device, defective pipe yarns that have been mistaken many times can be automatically discharged from the conveyance path system.
The processing efficiency of the pick-out device is increased, and defective threads that cannot be pulled out can be intensively reworked, etc., resulting in improved work efficiency.
