Description

Yarn winding machine

Technical Field

The present invention relates to a yarn winding machine including a plurality of winding units.

Background

In the automatic winder described in japanese patent application laid-open No. 2009-46269, a tray on which a yarn supplying bobbin is mounted is supplied from a bobbin replacing unit to a main line, and is supplied from the main line to a plurality of winding units. In addition, the tray, which is not supplied to the winding unit but is conveyed to the downstream end of the main line, is returned to the upstream end of the main line via the bypass line.

Disclosure of Invention

In the case of the automatic winder described in japanese patent application laid-open No. 2009-46269, in a state where the trays are sufficiently supplied to the respective winding units, the trays that are not supplied to the winding units are unnecessarily repeatedly moved in the main line and the bypass line. In such an automatic winder, in order to allow the yarn end to be paid out from the yarn supplying bobbin in the winding unit, a process of inserting the yarn end of the yarn supplying bobbin into the hole in the upper end of the core tube of the bobbin is generally performed in the bobbin replacing unit. Therefore, the tray is supplied from the bobbin replacing unit to the winding unit in a state where the yarn end is inserted into the hole at the upper end of the core tube of the bobbin. When the tray is unnecessarily conveyed as described above, there is a risk that: the yarn end of the yarn supplying bobbin drops (drops from the hole at the upper end of the core tube) due to vibration of the tray during transportation, and the yarn end cannot be subjected to yarn end-finding after being supplied to the winding unit. Further, when the yarn is conveyed in a state where the yarn end is dropped, there is a possibility that the dropped yarn is caught on a member forming the conveyance path of the tray.

The invention aims to provide a yarn winding machine which can supply necessary trays to winding units and can restrain unnecessary trays from being conveyed to the utmost.

The yarn winding machine of the present invention includes a plurality of winding units, a bobbin processing device, a tray conveying device, and a control device. The winding unit unwinds the yarn from the yarn supplying bobbin and winds the unwound yarn. The bobbin handling device performs a preparation process on the yarn supplying bobbin mounted on a tray, and collects the tray on which an empty bobbin from which the yarn is unwound by the winding unit is mounted. The tray conveying device conveys the tray between the plurality of winding units and the bobbin handling device. The tray conveying device is provided with a supply path, a recovery path, a return path, a conveying device and a tray delivery device. The supply path is a path for conveying the tray on which the yarn supplying bobbin is mounted to the plurality of winding units. The collecting path is a path for conveying the tray discharged from the plurality of winding units to the bobbin handling device. The return path is a path for returning the tray sent to the downstream side end of the supply path to the upstream side end of the supply path. The conveying device conveys the tray along the supply path, the recovery path, and the return path. The tray feeding device is provided in the return path and feeds the tray on the return path toward an upstream side end of the supply path. The bobbin handling device supplies the tray to one of the supply path and the return path. The control device causes the tray feeding device to perform a feeding operation for feeding the tray at a 1 st feeding speed, the 1 st feeding speed corresponding to a difference between a speed at which the tray is discharged from the plurality of winding units to the collection path and a speed at which the tray is directly supplied from the bobbin processing device to a portion of the supply path or the return path on a downstream side of the tray feeding device.

In the present invention, a tray feeding device is provided in the return path, and the tray feeding device is caused to feed the trays at a 1 st feeding speed corresponding to a difference between a speed at which the trays are discharged from the plurality of winding units to the collecting path (for example, the number of the trays discharged per predetermined time) and a speed at which the trays are directly supplied from the bobbin processing device to a portion of the supply path or the return path on the downstream side of the tray feeding device (for example, the number of the trays supplied per predetermined time). This makes it possible to supply a necessary number of trays (yarn supplying bobbins) to the plurality of winding units, and to stop the excess trays in the return path to prevent the trays from being unnecessarily repeatedly conveyed in the supply path and the return path.

In the yarn winding machine according to the present invention, the tray conveying device further includes a tray sensor provided at an end portion on a downstream side of the supply path and detecting the tray. The control device causes the tray feeding device to perform the feeding operation at a 2 nd feeding speed faster than the 1 st feeding speed until the tray is detected by the tray sensor after the start of winding by the plurality of winding units, and causes the tray feeding device to perform the feeding operation at the 1 st feeding speed after the tray is detected by the tray sensor.

Immediately after the winding by the winding unit is started, since the trays have not been sufficiently supplied to each winding unit, the number of trays on the return path is also small. Therefore, the tray may not be actually sent out even if the sending-out operation is performed. In addition, when the trays are sufficiently supplied to all the winding units, the tray that is not supplied to the winding units but is conveyed to the downstream side end portion of the supply path is detected by the tray sensor.

In the present invention, after the winding by the winding unit is started, the tray feeding device performs the feeding operation at the 2 nd feeding speed which is higher than the 1 st feeding speed until the tray is detected by the tray sensor. This can reduce the time required until the trays are sufficiently supplied to the respective winding units after the winding unit starts winding. After the tray sensor detects the tray, the tray feeding device is caused to perform a feeding operation at the 1 st feeding speed. This makes it possible to supply a necessary number of trays to the plurality of winding units while preventing the trays from being unnecessarily repeatedly conveyed on the supply path and the return path.

In the yarn winding device according to the present invention, the tray conveyor further includes a tray sensor provided at an end portion on the downstream side of the supply path and detecting the tray. The control device causes the tray feeding device to perform the feeding operation at a 2 nd feeding speed faster than the 1 st feeding speed during at least a part of a period until the tray is detected by the tray sensor after the bobbin processing device is returned from a stopped state, and causes the tray feeding device to perform the feeding operation at the 1 st feeding speed after the tray sensor detects the tray.

During the period from the stop of the bobbin processing device to the return thereof, the yarn is wound in the winding unit, and the tray on the supply path is supplied to each winding unit. Therefore, immediately after the bobbin handling device is returned from the stopped state, the number of trays on the return path may be small. In this case, the tray may not be actually discharged even if the discharging operation is performed. After the bobbin processing device is returned, if the trays are sufficiently supplied to all the winding units, the tray sensor detects the tray that is not supplied to the winding unit but is conveyed to the downstream end of the supply path.

In the present invention, after the bobbin handling device is returned from the stopped state, the tray feeding device is caused to perform the feeding operation at the 2 nd feeding speed which is higher than the 1 st feeding speed during at least a part of the period until the tray is detected by the tray sensor. This can shorten the time until the bobbin processing apparatus is returned to the state in which the trays are sufficiently supplied to the winding units. After the tray sensor detects the tray, the tray feeding device is caused to perform a feeding operation at the 1 st feeding speed. This makes it possible to supply a necessary number of trays to the plurality of winding units while preventing the trays from being unnecessarily repeatedly conveyed on the supply path and the return path.

In the yarn winding device according to the present invention, the control device causes the tray feeder to perform the feeding operation at the 1 st feeding speed when the bobbin processing device is returned from a stopped state, counts the number of trays discharged from the plurality of winding units after the bobbin processing device is returned from the stopped state, and causes the tray feeder to perform the feeding operation at the 2 nd feeding speed during a period from a time point when the counted number of trays exceeds a threshold until the tray is detected by the tray sensor when the counted number of trays exceeds the threshold.

In the case where the time from the stop state to the return of the bobbin processing device is short, the number of trays (the number of trays to be supplied to the winding unit) from which the yarn of the yarn supplying bobbin is unwound and discharged to the collection path in the plurality of winding units is small during the period from the stop state to the return of the bobbin processing device, and the state in which the trays are insufficiently supplied in each winding unit immediately after the return of the bobbin processing device is not achieved.

In the present invention, when the bobbin handling device is returned from the stopped state, the tray transport device is caused to perform the feeding operation at the 1 st feeding speed, and the number of trays discharged from the plurality of winding units is counted. When the counted number of trays exceeds a threshold value, the tray feeding device is caused to perform a feeding operation at the 2 nd feeding speed during a period from a time point when the threshold value is exceeded until the tray sensor detects the tray. Accordingly, when the tray is not sufficiently supplied to each winding unit after the bobbin processing device is returned, the time until the tray is sufficiently supplied to each winding unit can be shortened as much as possible.

On the other hand, when the counted number of trays is equal to or less than the threshold value, the tray feeding device continues to operate at the 1 st feeding speed. This can avoid the tray from being fed out from the tray feeder more than necessary.

In the yarn winding device of the present invention, the 2 nd feeding speed is a maximum speed at which the feeding operation can be performed in the tray feeding device.

In the present invention, in a situation where there is a high possibility that the tray will not be delivered even though the tray delivery device performs the delivery operation, the tray delivery device performs the delivery operation at the maximum speed, and thus the time until the trays are sufficiently supplied to each winding unit can be further shortened.

In the yarn winding device according to the present invention, the bobbin handling device supplies the tray to a portion of the return path upstream of the tray feeder. The control device causes the tray feeding device to perform the feeding operation at least once in addition every time the feeding operation is performed a predetermined number of times.

When the bobbin handling device supplies the tray to a portion of the return path upstream of the tray feeding device, only the tray fed from the tray feeding device is supplied to the supply path. Therefore, the space between the trays is likely to be larger than in the case where the trays are supplied from the bobbin processing device to the portion of the supply path or the return path on the downstream side of the tray feeding device. In this case, even if the tray feeding device performs the feeding operation at the 1 st feeding speed, a delay in the supply of the tray may occur in a certain winding unit.

In the present invention, when only the tray fed out from the tray feeding device is supplied to the supply path, the feeding operation is performed at least once again every predetermined number of times of the feeding operation after the tray feeding device is caused to perform the feeding operation at the 1 st feeding speed. This increases the number of trays on the supply path, and makes it possible to prevent a delay in the supply of trays to the winding unit.

In the yarn winding device of the present invention, the control device sets the number of times the tray feeding device performs the feeding operation for each predetermined cycle, and sets N as a natural number to be the [ N-1 ]]In one of said periods from saidThe number of the trays discharged by the plurality of winding units is set as A_N-1And will be in [ N-1 ]]B is the number of the trays directly supplied from the bobbin handling device to the upstream side of the tray feeding device in the supply path or the return path in each of the cycles_N-1In this case, the number of times the tray feeding device performs the feeding operation in the nth cycle is set to (a)_N-1-B_N-1) Next, the process is carried out.

According to the present invention, the number of times the feeding operation is performed in the nth cycle is set to (a)_N-1-B_N-1) The tray can be fed out from the tray feeder at the 1 st feeding speed.

In the yarn winding device according to the present invention, the control device may stop any one of the predetermined delivery operations when the tray is directly supplied from the bobbin handling device to a portion of the supply path or the return path downstream of the tray delivery device in each cycle, and may stop the delivery operation when the delivery operation is predetermined after the supply of the tray, and stop the delivery operation when the delivery operation is not performed in [ N-1 ]]C in the predetermined sending operation in one cycle_N-1When the next sending-out operation is not performed, increasing the number of times of the sending-out operation performed by the tray sending-out device in the Nth cycle by C_N-1Next, the process is carried out.

In the present invention, when a tray is directly supplied from the bobbin processing device to a portion of the supply path or the return path downstream of the tray feeding device in each cycle, if a feeding operation is scheduled after the supply of the tray, any one of the scheduled feeding operations is not performed. This makes it possible to set the number of trays to be supplied to the supply path to a more appropriate number in each cycle. In addition, when in the [ N-1 ]]C in the predetermined sending operation in one cycle_N-1If the sub-feeding operation is not performed, the number of times of feeding operation by the tray feeder in the Nth cycle is increased by C_N-1Next, the process is carried out. Thereby, even when the yarn feeding operation is stopped by the supply of the tray from the yarn bobbin processing deviceIn the case of the operation, the tray supply shortage does not occur.

In the yarn winding device according to the present invention, the control device includes a plurality of winding control units, a bobbin handling control unit, and a delivery control unit. The winding control section is provided separately from the plurality of winding units and controls the winding units. The bobbin processing control unit controls the bobbin processing device. The delivery control unit controls the tray delivery device. The plurality of winding control units and the delivery control unit are configured to be able to communicate with each other, and the bobbin handling control unit and the delivery control unit are configured to be able to communicate with each other.

In order to feed the trays from the feeding device at the speed described above, the feeding control unit needs to grasp information on the number of trays supplied from the bobbin processing device and information on the number of trays discharged from the winding unit. In the present invention, the delivery control unit can communicate with the plurality of winding control units and the bobbin handling control unit, and thus the delivery control unit can grasp and control the information as described above.

Effects of the invention

According to the present invention, a necessary number of trays can be supplied to a plurality of winding units, and excess trays can be stopped in the return path to prevent the trays from being unnecessarily repeatedly conveyed in the supply path and the return path.

Detailed Description

[ embodiment 1]

Hereinafter, preferred embodiment 1 of the present invention will be described. The following description will appropriately use the directions shown in the drawings.

< integral Structure of yarn winding machine >

As shown in fig. 1, the yarn winding machine 1 includes a plurality of winding units 11 arranged in the left-right direction, a bobbin processing device 12 disposed at the right end portion, a control box 13 disposed at the left end portion, and a tray conveying device 14 disposed in a region where the plurality of winding units 11 are arranged (a region between the bobbin processing device 12 and the control box 13).

< winding Unit >

The winding unit 11 unwinds a yarn from a yarn supplying bobbin S (shown by a black circle) attached to a tray T supplied from a supply path 31 described later, and winds the unwound yarn to form a package (not shown). The winding unit 11 discharges the tray T on which the empty bobbin E (shown by a hollow circle) after unwinding the yarn from the yarn supplying bobbin S is mounted to a recovery path 34 described later.

< bobbin handling device >

The bobbin processing device 12 conveys (supplies) the tray T with the yarn supplying bobbin S attached thereto to the tray conveyor 14, and collects the tray T with the empty bobbin E attached thereto, which is returned from the tray conveyor 14. The bobbin processing device 12 performs a preparatory process (e.g., a head-finding process) for performing a winding process by the winding unit 11 on the yarn supplying bobbin S before being supplied to the winding unit 11. The bobbin processing device 12 performs post-processing (e.g., remaining yarn removing processing) on the empty bobbin E collected from the winding unit 11. The contents of the preliminary treatment and the post-treatment by the bobbin processing device 12 are not limited to the end-finding treatment and the excess yarn removing treatment. In the present embodiment, the yarn supplying bobbin S is supplied to the bobbin handling device 12 from a not-shown spinning machine, but the yarn supplying bobbin S spun by the spinning machine may be supplied to the bobbin handling device 12 by an operator.

< control box >

The control box 13 has an operation panel 16. The operation panel 16 is provided on the front surface of the control box 13, and enables an operator to input winding conditions and the like. Further, the operation panel 16 displays the operation status, abnormality, and the like of the plurality of winding units 11.

< tray conveying device >

The tray transport device 14 transports the tray T between the bobbin processing device 12 and the plurality of winding units 11. As shown in fig. 1, the tray conveying device 14 has a supply path 31, a return path 32, a plurality of individual paths 33, and a recovery path 34. The tray T on each path is conveyed by a conveyor 39 (see fig. 3) provided on each path and composed of a conveyor belt or the like. Note that the arrow in fig. 1 indicates the conveying direction of the tray T (the same applies to other figures).

The supply path 31 is located on the rear side of the plurality of winding units 11, and extends in the left-right direction across the plurality of winding units 11. The bobbin processing device 12 is connected to a right end (upstream end) of the supply path 31. Thereby, the tray T is directly supplied from the bobbin processing device 12 to the supply path 31. The tray T supplied to the supply path 31 is conveyed from the right side toward the left side on the supply path 31. The tray conveying device 14 further includes a tray sensor 29 for detecting the remaining trays T conveyed to the downstream end (left end) of the supply path 31.

The return path 32 extends in the left-right direction on the rear side of the supply path 31. That is, the supply path 31 is located between the winding unit row and the return path 32. Both ends of the return path 32 are connected to both ends of the supply path 31. On the return path 32, the tray T is conveyed from the left side to the right side. Thereby, the remaining tray T conveyed to the downstream end (left end) of the supply path 31 is conveyed to the upstream end (left end) of the return path 32 via the connecting portion. That is, the remaining tray T conveyed to the downstream end of the supply path 31 can be returned to the upstream end (right end) of the supply path 31 via the return path 32.

A tray stopper 35 (a "tray feeding device" of the present invention) is provided in a middle portion of the return path 32. The tray delivery device is a device capable of delivering (delivering) the tray T at a required speed (pace) (frequency). By releasing the restriction by the tray stopper 35 in a state where the conveyor 39 is driven, the tray T can be carried out. The tray stopper 35 is preferably provided at a downstream side end portion (right end portion) of the return path 32. As shown in fig. 2 (a) and (b), the tray stopper 35 includes an arm 41 and two rollers 42 and 43. The arm 41 is connected to a motor or the like, not shown, and can swing about a shaft 41a extending in the vertical direction. In addition, the arm 41 has two portions 41b, 41c extending in two directions apart. The portion 41b is located on the downstream side (right side) of the return path 32 than the portion 41 c.

The roller 42 is provided at the tip end portion of the portion 41b of the arm 41. The roller 42 is supported rotatably about a shaft 42a extending in the vertical direction by a portion 41b of the arm 41. The roller 43 is provided at the tip end portion of the portion 41c of the arm 41. The roller 43 is supported rotatably about a shaft 43a extending in the vertical direction at a portion 41c of the arm 41.

The tray stopper 35 assumes a posture as shown in fig. 2 (a) when the tray T is not being fed out. In this state, the roller 42 can contact the tray T on the return path 32, and the roller 43 does not contact the tray T on the return path 32. Thereby, the tray T conveyed along the return path 32 stops further conveyance by contacting the roller 42. While the tray stopper 35 is held in the state of fig. 2 (a), the tray T conveyed along the return path 32 is stopped by the tray stopper 35 and is accumulated on the return path 32.

When the tray T is fed out, the tray stopper 35 is caused to perform the following feeding-out operation: after the arm 41 is swung clockwise as viewed from above about the shaft 41a to be in the state of fig. 2 (b), the arm 41 is swung in the opposite direction to return to the state of fig. 2 (a). When the state of fig. 2 (b) is reached, the roller 42 does not contact the tray T on the return path 32, and the roller 43 can contact the tray T on the return path 32. Thus, the tray T whose conveyance has been stopped by the roller 42 is sent out toward the feeding path 31. In addition, the tray T to be fed next is stopped from being conveyed by the roller 43. When the arm 41 is swung in the opposite direction and returned to the state of fig. 2 (a), the tray T whose conveyance is stopped by the roller 43 is stopped by the roller 42.

A clogging eliminator (bridge breaker)36 is provided at a connection portion to the supply path 31 on the downstream side of the return path 32. The jam clearance 36 prevents so-called jamming from occurring, in which the tray T fed from the tray stopper 35 and the tray T fed from the bobbin processing device 12 to the supply path 31 are caught and jammed at the connecting portion between the return path 32 and the supply path 31.

The individual paths 33 are positioned on the front side of the supply path 31 and arranged in the left-right direction. The individual paths 33 are provided so as to correspond to the winding units 11, respectively. Each individual path 33 is bent halfway and extends in the front-rear direction, and has a rear end connected to the supply path 31 and a front end connected to the recovery path 34. The connection portion of the individual path 33 to the supply path 31 is inclined with respect to the front-rear direction so as to go to the front side and the left side. In addition, three trays T can be accommodated on the individual path 33. That is, two trays T can be accommodated between the tray T located at the winding position of the individual path 33 and the supply path 31. Thus, when the trays T conveyed from the right side toward the left side on the supply path 31 are conveyed to the connection portion of the supply path 31 connected to the individual path 33, the trays T are conveyed from the supply path 31 to the individual path 33 in the case where the number of trays T accommodated in the individual path 33 is two or less. On the other hand, in the case where the individual path 33 has accommodated three trays T, the trays T are conveyed directly to the left side on the supply path 31. That is, the trays T are supplied to the plurality of individual paths 33 in order from the individual path 33 located on the right side.

The winding unit 11 is provided on each individual path 33. The winding unit 11 unwinds and winds the yarn from the yarn supplying bobbin S attached to the tray T of the separate path 33 located at the winding position (in the present embodiment, the position of the tray T accommodated in the foremost position among the three trays T of the separate path 33). When the yarn unwinding from the yarn supplying bobbin S is completed, the winding unit 11 discharges the tray T, to which the empty bobbin E from which the yarn has been unwound, from the winding position to the collection path 34 by a tray discharge portion, not shown. In this way, the tray T located on the rear side of the winding position moves to the front side, and the winding unit 11 can unwind the yarn from the new yarn supplying bobbin S and wind the yarn.

The collecting path 34 extends in the left-right direction on the front side of the plurality of individual paths 33, and the bobbin processing device 12 is connected to the right end (downstream end) of the collecting path 34. The tray T discharged by the winding unit 11 is conveyed from the individual path 33 to the recovery path 34. On the recovery path 34, the tray T is conveyed from the left side to the right side, and finally returned to the bobbin processing device 12. Thus, the tray T is collected by the bobbin processing device 12.

Electrical structure of yarn winding machine

Next, an electrical structure of the yarn winding machine 1 will be explained. As shown in fig. 3, the yarn winding machine 1 includes an MCU (Multi Control Unit) 51, a plurality of winding Control units 52, a bobbin processing Control Unit 53, a conveyance Control Unit 54, a delivery Control Unit 55, and a communication-managing substrate 56.

The MCU51 is provided in the control box 13. When a signal related to setting of the yarn winding machine 1 is input from the operation panel 16, the MCU51 transmits a signal for setting to the winding control unit 52, the bobbin processing control unit 53, the conveyance control unit 54, and the delivery control unit 55 based on the input signal. The MCU51 also transmits a signal to the operation panel 16 to display the operating state, abnormality, and the like of the winding unit 11.

The plurality of winding control units 52 are provided separately for the plurality of winding units 11, and control the operation of the corresponding winding unit 11. The bobbin processing control unit 53 is provided in the bobbin processing device 12, and controls the operation of the bobbin processing device 12. The conveyance control unit 54 is provided in the conveyance device 39, and controls the operation of the conveyance device 39 (such as a motor for driving the conveyance belt). The feed control unit 55 is provided in the tray stopper 35, and controls the operation of the tray stopper 35.

The MCU51, the plurality of winding control units 52, the bobbin processing control unit 53, the conveyance control unit 54, the delivery control unit 55, the communication-managing substrate 56, and the tray sensor 29 are connected to each other, and communication is possible between them. The communication-completed substrate 56 is a substrate for completing the communication. In embodiment 1, a combination of the MCU51, the plurality of winding control units 52, the bobbin processing control unit 53, the conveyance control unit 54, the delivery control unit 55, and the communication-completed substrate 56 corresponds to the "control device" of the present invention.

Feed-out control based on tray stopper

Next, the tray T feeding control by the tray stopper 35 will be described. The feeding control section 55 performs processing according to the flow shown in fig. 4 in order to feed the tray T through the tray stopper 35. The process of fig. 4 is started when the operation of the yarn winding machine 1 (winding in the plurality of winding units 11) is started.

To describe the process of fig. 4 in more detail, the feed control unit 55 starts the maximum feed control when the operation of the yarn winding machine 1 is started (S101). The maximum feeding control is a control for causing the tray stopper 35 to perform a feeding operation (for example, a feeding operation for 1 second) at a maximum speed ("2 nd feeding speed" in the present invention). Then, the feeding control unit 55 continues the maximum feeding control while the tray sensor 29 does not detect the tray T (S102: no). Whether or not the bobbin processing device 12 is stopped is determined based on a signal from the bobbin processing control section 53.

When the tray sensor 29 detects the tray T (S102: YES), the feeding control section 55 switches from the maximum feeding control to the normal feeding control (S103). The general feed control will be described in detail later. The feeding control unit 55 continues the normal feeding control while the bobbin processing device 12 is not stopped due to an abnormality or the like (S104: no).

When the bobbin processing device 12 is in the stopped state due to an abnormality or the like (yes in S104), the delivery control section 55 waits until the bobbin processing device 12 is returned from the stopped state (no in S105). The determination of whether or not the bobbin processing device 12 has returned from the stopped state in S105 is performed based on a signal from the bobbin processing control unit 53.

Here, the normal feeding control is continued even while the bobbin processing device 12 is in the stopped state. When the bobbin processing device 12 is in a stopped state, each winding unit 11 continues winding until the winding of a predetermined number of packages is completed. When the winding of the predetermined number of packages in the plurality of winding units 11 is completed and a period of time has elapsed since the signal indicating that the winding is completed is no longer output from any of the winding units 11, the number K of times of the feeding operation per cycle U calculated under the normal feeding control as described later is counted_NThe value becomes 0 or less, and the sending operation is not performed.

When the bobbin processing device 12 is returned from the stopped state (yes in S105), the number of trays T discharged from the plurality of winding units 11 thereafter starts to be counted (S106). The counting of the trays T in S106 is performed based on the signal indicating that the winding is completed, which is transmitted from each winding unit 11.

When the counted number of trays T exceeds the threshold (S107: yes), the feeding control unit 55 switches from the normal feeding control to the maximum feeding control (S108). Then, the feeding control section 55 continues the maximum feeding control until the tray sensor 29 detects the tray T (S109: NO). When the tray T is detected by the tray sensor 29 (S109: YES), the process returns to S103.

If the counted number of trays T does not exceed the predetermined threshold (S107: no), the process returns to S107 if the tray sensor 29 does not detect the trays T (S110: no). When the tray T is detected by the tray sensor 29 (S110: YES), the process returns to S104.

< Normal outgoing processing >

Next, a normal sending process will be described. The normal feeding process is a process of setting the number of times the tray stopper 35 is fed for each predetermined cycle U and feeding the tray stopper 35 based on the set number of times. Note that the speed at which the tray stopper 35 is caused to perform the feeding operation in the normal feeding process corresponds to the "1 st feeding speed" of the present invention. In the present application, "speed" refers to "frequency" and/or "number of occurrences per prescribed time".

The normal sending process is specifically a process according to the flow shown in fig. 5. To describe in more detail, in the normal sending process, the sending control unit 55 first resets the variable N (N is a natural number) to 1 (S201).

Subsequently, the sending control part 55 will send the signal in the Nth cycle U_NNumber of times K of internally carrying out the feeding operation_NIs set as (A)_N-1-B_N-1+C_N-1) Next (S202). I.e. the number of times K_NRatio (A)_N-1-B_N-1) Second order multiple C_N-1Next, the process is carried out. Here, A is_N-1Is in the [ N-1 ]]One period U_N-1The number of trays T discharged from the plurality of winding units 11. B is_N-1Is in the period U_N-1The number of trays T to be fed from the bobbin processing device 12 to the feed path 31. C_N-1Is in the period U_N-1The number of times of the sending operation is cancelled. Cancellation of the sending-out operation will be described later. Wherein, A in the case where N is 1_N-1、B_N-1、C_N-1Namely A₀、B₀、C₀Are all set to 0. Furthermore, C_N-1Not necessarily, C is not considered_N-1According to A_N-1And B_N-1Calculate K_N。

If the number of times K_NGreater than 0 (S203: Yes), in the period U_NInternally operated feed-out operation K_NDetermining the period U in a secondary manner_NTiming of the sending operation (S204). In this case, it is preferable that the period U is set_NThe timing of the sending operation is determined so that the sending operation is performed at as uniform intervals as possible. Then, when the feed timing is reached (S205: YES), the feed control section 55 causes the tray stopper 35 to perform a feed operation (S206). When all the feeding operations of one cycle are completed by the feeding operation of S206 (yes in S207), the process proceeds to S211. The other partyWhen all the send-out operations in one cycle have not been completed (no in S207), the process proceeds to S208. If the timing is not the delivery timing (no in S205), the process proceeds to S208.

In S208, it is determined whether or not the tray T is supplied from the bobbin processing device 12 to the supply path 31. If the tray T is not supplied from the bobbin processing device 12 to the supply path 31 (S208: no), the process returns to S205. When the tray T is supplied from the bobbin processing device 12 to the supply path 31, the nth cycle U is performed_NThe last delivery operation among the delivery operations to be performed after the internal reservation is cancelled and is not performed (S209). Then, after the sending operation in S209 is canceled, in the period U_NIf there is any more send-out operation to be performed (S210: NO), the process returns to S205.

On the other hand, if all the send-out operations for one cycle have been completed by the cancellation of the send-out operation at S208 (YES at S210), the process proceeds to S211. In addition, at K_NIf the value is 0 or less (S203: NO), the process proceeds to S211. In S211, the variable N is increased by 1 (updated to [ N +1]]). Then, the transmission control unit 55 updates the variable N in S211 and returns to S202.

Here, a specific example of the feeding of the tray T from the tray stopper 35 in each cycle U in the case where the normal feeding control is performed as described above will be described. Fig. 6 is diagrams showing examples 1 to 3 of the timing of the discharge of the tray T from the plurality of winding units 11, the supply of the tray T from the bobbin processing device 12, and the feed operation of the tray stopper 35 in the case where one cycle is 10 seconds. In fig. 6, "tray discharge" indicates discharge of the tray T from the plurality of winding units 11. Further, "tray supply" indicates supply of the tray T from the bobbin processing device 12. The "feeding operation" indicates a feeding operation by the tray stopper 35.

In addition, 1, 2, ·, 9, and 10 in each cycle in FIG. 6 respectively represent periods of 0 to 1 second, 1 to 2 seconds, 2 to 3 seconds, 3 to 4 seconds, 4 to 5 seconds, 5 to 6 seconds, 6 to 7 seconds, 7 to 8 seconds, 8 to 9 seconds, and 9 to 10 seconds from the start time point of each cycle. In the following description, for example, a period of 0 to 1 second may be a period of "1". In fig. 6, the timing of discharging the tray T from the winding unit 11, the timing of supplying the tray T from the bobbin processing device 12, and the timing of performing the feeding operation are hatched. Note that adding x to the hatching line indicating the timing of the sending operation indicates canceling the sending operation.

In the case of example 1, in the period U_N-1Three trays T (A) are discharged from a plurality of winding units 11_N-13). In addition, in the period U_N-1One tray T (B) is supplied from the bobbin processing device 12_N-11). In example 1, in the period U_N-1Since the tray T is not fed from the tray stopper 35, the feeding of the tray T is not canceled from the tray stopper 35 (C)_N-1＝0)。

Thus, in the case of example 1, the period U_NNumber of times of inner feed-out operation K_NIs set to 2(═ 3-1+0) times. In addition, in the period U_NIn order to perform these two sending operations at substantially equal intervals, the periods of "5" and "10" are determined as the timings of the sending operations. In addition, in the period U_NThe bobbin processing device 12 does not supply the tray T (B)_N0). Therefore, the feeding of the tray T is not canceled from the tray stopper 35 (C)_N0). In addition, in the period U_NTwo trays T (A) are discharged from a plurality of winding units 11_N2). Thus, the [ N +1 th]One period U_N+1Number of times of inner feed-out operation K_N+1Is set to 2(═ 2-0+0) times. In addition, in the period U_N+1The periods of "5" and "10" are also determined as the timing of the sending operation.

In example 2, A_N-1、B_N-1、C_N-1Period U as in example 1_NNumber of times of inner feed-out operation K_NThe number of times is also set to 2, and the periods of "5" and "10" are also determined as the timings of the sending-out operation. In example 2, in the period U_NIn the period of "3" and "8", the tray T (B) is supplied from the bobbin processing device 12_N2). When the tray T is supplied from the bobbin handling device 12 during the period "3", the supply is scheduled to be performed during the following periods "5" and "10Therefore, the last sending operation among them, that is, the sending operation in the period of "10" is cancelled. In example 2, when the sending operation is performed in the period of "5", the period U is set to be the period U_NAll the sending operations in (S207: YES) are completed. In this case, the cycle U is determined by the time point when the tray T is supplied from the bobbin processing device 12 during the period "8_NAll the feeding operations in the (10) period are completed (the feeding operation is cancelled), so that the feeding operation is not cancelled.

Thus, in example 2, in the period U_NThe internal feed-out operation is cancelled once (C)_N1). In addition, in the period U_NTwo trays T (A) are discharged from a plurality of winding units 11_N2). Thus, the period U_N+1Number of times of inner feed-out operation K_N+1Is set to 1(═ 2-2+1) times.

In example 3, A_N-1、B_N-1、C_N-1Period U same as examples 1 and 2_NNumber of times of inner feed-out operation K_NThe number of times is also set to 2, and the periods of "5" and "10" are also determined as the timings of the sending-out operation. In example 3, in the period U_NIn the meantime, the tray T (B) is supplied from the bobbin processing device 12 to the supply path 31 during the periods of "1" and "3_N2). At the time point when the tray T is supplied from the bobbin processing device 12 to the supply path 31 during the period "1", since the feeding operation is scheduled during the subsequent periods "5" and "10", the feeding operation during the period "10" which is the last feeding operation among these is cancelled. Further, at the time point when the tray T is supplied from the bobbin processing device 12 to the supply path 31 in the period of "3", since the feeding operation is scheduled in the period of "5" thereafter, the feeding operation in the period of "5" is cancelled. In example 3, the cycle U is set to be at the time point when the tray T is supplied from the bobbin processing device 12 to the supply path 31 during the period "3_NAll the sending operations in (S210: YES) are completed.

Thus, in example 3, in the period U_NThe internal feed-out operation is cancelled 2 times (C)_N2). In addition, in the period U_NFrom a plurality of windingsThe unit 11 discharges two trays T (A)_N2). Thus, the period U_N+1Number of times of inner feed-out operation K_N+1Is set to 2(═ 2-2+2) times.

< Effect >

Here, when the tray T is fed out toward the feed path 31 by performing the feeding operation more than necessary by the tray stopper 35 when the tray T is sufficiently fed to each winding unit 11, the tray T is not fed to any winding unit 11 but is unnecessarily repeatedly conveyed on the feed path 31 and the return path 32. As described above, the yarn supplying bobbin S conveyed from the tray T is conveyed in a state where the yarn end is inserted into the upper end of the core tube of the yarn supplying bobbin S so as to enable yarn end-cutting in the winding unit 11. Therefore, when the tray T on which the yarn supplying bobbin S is mounted is unnecessarily conveyed as described above, there is a concern that: the yarn end of the yarn supplying bobbin S falls from the core tube due to vibration of the tray T during conveyance, and the yarn end is not caught by the winding unit 11 any more, or the falling yarn end is caught by a member forming the supply path 31 and the return path 32.

Then, in embodiment 1, the tray stopper 35 is caused to perform the feeding operation at the 1 st feeding speed (this 1 st feeding speed corresponds to the difference between the speed at which the tray T is discharged from the plurality of winding units 11 to the collecting path 34 and the speed at which the tray T is directly supplied from the bobbin processing device 12 to the supply path 31). Specifically, the number of times of the sending operation is set for each predetermined cycle U, and the sending operation is performed in the cycle U_N-1The number of trays T discharged from the plurality of winding units 11 is A_N-1The number of trays T directly supplied from the bobbin processing device 12 to the supply path 31 is B_N-1The number of cancelled sending-out operations is C_N-1In the case of (2), will be in period U_NThe number of times of the sending operation is set to (A)_N-1-B_N-1+C_N-1) Next, the process is carried out. This makes it possible to supply a necessary number of trays T (yarn supplying bobbins S) to the plurality of winding units 11, and to stop the excess trays T in the return path 32, thereby preventing the trays T from being unnecessarily repeatedly conveyed through the supply path 31 and the return path 32.

In addition, when in the period U_NWhen the tray T is supplied from the bobbin processing device 12 to the supply path 31, if the feeding operation is scheduled after the supply of the tray T, the last feeding operation in the scheduled feeding operation is cancelled. This makes it possible to reduce the period U compared with the case where the sending operation is not canceled_NThe number of trays T internally supplied to the supply path 31 is set to a more appropriate number. In addition, correspondingly, in the period U_N-1C in predetermined delivery operation_N-1When the next sending operation is cancelled, the operation will be performed in the period U_NThe number of times of the internal feeding operation is set to be a ratio (A)_N-1-B_N-1) Second order multiple C_N-1Next to (A)_N-1-B_N-1+C_N-1) Next, the process is carried out. Thus, even when the sending operation is cancelled, the sending operation is cancelled in the period U_NThe tray supply shortage does not occur therein.

Immediately after the operation of the yarn winding machine 1 (winding by the winding unit 11) is started, the number of trays T on the return path 32 is small because the trays T are not sufficiently supplied to each winding unit 11. Therefore, the tray T may not be actually sent out even if the sending-out operation is performed. When the trays T are sufficiently supplied to all the winding units 11, the tray T that is not supplied to the winding units 11 but is conveyed to the end portion on the downstream side of the supply path 31 is detected by the tray sensor 29.

Then, after the operation of the yarn winding machine 1 is started, the tray stopper 35 is caused to perform the feeding operation at the 2 nd feeding speed (based on the maximum feeding control) which is higher than the 1 st feeding speed set as described above until the tray sensor 29 detects the tray T. This can shorten the time until the tray T is sufficiently supplied to each winding unit 11 after the operation of the yarn winding machine 1 is started as much as possible. Then, after the tray sensor 29 detects the tray T, the tray stopper 35 performs the feeding operation at the 1 st feeding speed (switching to the normal feeding control). This makes it possible to supply a necessary number of trays T to the plurality of winding units 11 while preventing the trays T from being unnecessarily repeatedly conveyed on the supply path 31 and the return path 32.

During the period from the stop of the bobbin processing device 12 to the return thereof, the yarn is wound in the winding unit 11, and the tray T on the supply path 31 is supplied to each winding unit 11. Therefore, immediately after the bobbin processing device 12 is returned from the stopped state, the trays T may not be sufficiently supplied to each winding unit 11, and the number of trays T on the return path 32 may be small. Therefore, the tray T may not be actually sent out even if the sending-out operation is performed. When the trays T are sufficiently supplied to all the winding units 11, the tray T that is not supplied to the winding units 11 but is conveyed to the end portion on the downstream side of the supply path 31 is detected by the tray sensor 29.

However, if the bobbin processing device 12 is in a stopped state and the time period until the bobbin processing device is returned is short, the number of trays T supplied from the supply path 31 to the winding unit 11 during this time period is small, and the trays T are not sufficiently supplied to each winding unit 11.

Then, when the bobbin processing device 12 is returned from the stopped state, the tray stopper 35 is caused to perform the feeding operation at the 1 st feeding speed (based on the normal feeding control), and the number of trays T to be discharged from the plurality of winding units 11 after that is counted. When the counted number of trays T exceeds the threshold value a, the tray stopper 35 is caused to perform the feeding operation at the 2 nd feeding speed (based on the maximum feeding control) which is higher than the 1 st feeding speed during a period from the time when the threshold value is exceeded to the time when the tray sensor 29 detects the tray. This can shorten the time until the tray T is sufficiently supplied to each winding unit 11 after the bobbin processing device 12 is returned. Then, after the tray sensor 29 detects the tray T, the tray stopper 35, i.e., the feeding device, performs the feeding operation at the 1 st feeding speed (switching to the normal feeding control). This makes it possible to supply a necessary number of trays T to the plurality of winding units 11 while preventing the trays T from being unnecessarily repeatedly conveyed on the supply path 31 and the return path 32.

On the other hand, after the bobbin processing device 12 is returned from the stopped state, until the tray sensor 29 detects the trays, if the counted number of trays T does not exceed the threshold value a, the tray stopper 35 continues the feeding operation at the 1 st feeding speed (based on the normal feeding control). This makes it possible to supply a necessary number of trays T to the plurality of winding units 11 while preventing the trays T from being unnecessarily repeatedly conveyed on the supply path 31 and the return path 32.

Further, since the 2 nd feeding speed is the maximum speed of the tray stopper 35, the time until the tray T is sufficiently supplied to each winding unit 11 after the operation of the yarn winding machine 1 is started and/or after the bobbin handling device 12 is returned can be further shortened.

In order to perform the normal feeding control as described above, the feeding control unit 55 needs to know the number of the trays T discharged from the plurality of winding units 11 and the number of the trays T supplied from the bobbin processing device 12. In embodiment 1, the delivery control unit 55 can communicate with the winding control unit 52 and the bobbin processing control unit 53 of each winding unit, and can grasp and process the information thereof.

[ 2 nd embodiment ]

Next, a preferred embodiment 2 of the present invention will be described. As shown in fig. 7, in the yarn winding machine 101 according to embodiment 2, in contrast to the yarn winding machine 1 according to embodiment 1, the bobbin processing device 102 is disposed on the left side of the tray conveying device 104, and the control box 103 is disposed on the right side of the tray conveying device 104. In response to this, the left end of the return path 32 of the tray conveying device 104 is connected to the bobbin processing device 102. In embodiment 2, the bobbin processing device 102 supplies the tray T to the upstream end of the return path 32 (the portion on the upstream side of the tray stopper 35).

In embodiment 2, the feeding control unit 55 also causes the tray stopper 35 to perform the feeding operation by control according to the flow of fig. 4. However, in embodiment 2, the processing under normal delivery control is different from that in embodiment 1. The normal delivery control according to embodiment 2 is a process according to the flow of fig. 8. To describe in more detail, in embodiment 2, the feeding control unit 55 first resets the variable M to 0 in the normal feeding control (S301), and waits until the tray T is discharged from a certain winding unit 11 (S302: no). When the tray T is discharged from any one of the winding units 11 (YES in S302), the tray stopper 35 is caused to perform a feeding operation (S304), and the variable M is increased by 1 (updated to [ M +1]) (S304). Further, the determination of S302 is made based on the signal from the winding unit 11. When the value of the variable M is smaller than the threshold Ma (S305: no), the process returns to S302, and when the value of the variable M is equal to or greater than the threshold Ma (S305: yes), the tray stopper 35 is once fed out (S306), and the process returns to S301. Thus, in embodiment 2, the feeding operation is performed once more for each Ma feeding operation.

In embodiment 1, the tray T fed from the bobbin processing device 12 and the tray T fed from the tray stopper 35 are directly fed to the feeding path 31. In contrast, in embodiment 2, the bobbin processing device 12 feeds the tray T to the portion of the return path 32 upstream of the tray stopper 35, and only the tray T fed out by the tray stopper 35 is fed to the feed path 31. Therefore, in this case, when the tray T is discharged from one of the winding units 11, if only the tray stopper 35 is operated to feed, the interval between the trays T is increased, and there is a possibility that the supply of the tray T is delayed in one of the winding units 11.

Thus, in embodiment 2, the feeding operation is performed once more for each Ma feeding operations. This can prevent a delay in feeding the tray T to the winding unit 11.

In embodiment 2, the feeding operation is performed only once in S305, but the feeding operation may be performed 2 or more times in S305.

The bobbin processing apparatus 202 supplies the tray T to which the yarn supplying bobbins S of the same yarn type are attached from the tray supplying portions 202a and 202 b.

The tray supply portion 202a is connected to the right end (upstream end) of the supply path 31. Thereby, the tray T supplied from the tray supply portion 202a is directly supplied to the upstream end of the supply path 31. In embodiment 3, the tray conveying device 204 includes a connection path 215 that connects the tray supply portion 202b and a portion of the return path 32 between the tray stopper 35 and the jam clearing device 36. Thereby, the tray T supplied from the tray supply portion 202b is supplied to the portion of the return path 32 on the downstream side of the tray stopper 35 via the connection path 215.

In embodiment 3 as well, the tray stopper 35 is caused to perform the feeding operation by the control according to the flow shown in fig. 4 and 5, as in embodiment 1. However, in the case of embodiment 3, the period U is set in the control of fig. 5_NB is the total number of trays T supplied from the two tray supply portions 202a and 202B of the bobbin processing apparatus 202_N。

The tray T supplied from the tray supply portion 302a and the tray T supplied from the tray supply portion 302b are subjected to preparation processing for the yarn supplying bobbin S by different mechanisms (preparation devices) in the bobbin processing device 302. The bobbin processing device 302 supplies a tray T to which yarn supplying bobbins S of the same yarn type are attached from the tray supply portions 302a and 302 b.

Further, the tray supply portion 302a is connected to an upstream end (left end) of the return path 32. The tray conveying device 304 further includes a connection path 315 that connects the tray supply portion 302b and a portion of the return path 32 on the downstream side of the tray stopper 35. In embodiment 4, the jam clearing device 36 is provided at the downstream end of the supply path 31.

In embodiment 4 as well, the tray stopper 35 is caused to perform the feeding operation by the control according to the flow shown in fig. 4 and 8, as in embodiment 2.

Next, a preferred embodiment 6 of the present invention will be described. As shown in fig. 12, in the yarn winding machine 501 according to embodiment 6, the bobbin treatment device 502 is disposed on the left side of the tray conveyance device 504, and the control box 503 is disposed on the right side of the tray conveyance device 504. The bobbin processing apparatus 502 supplies the trays T from the two tray supply units 502a and 502 b. That is, there are two tray supply outlets from the bobbin processing device 502 to the winding unit 11. The tray T supplied from the tray supply portion 502a and the tray T supplied from the tray supply portion 502b are subjected to preparation processing for the yarn supplying bobbin S by different mechanisms (preparation devices) in the bobbin processing device 502. In embodiment 6, the types of yarns wound around the yarn supplying bobbins S attached to the tray T are different in the tray supplying portions 502a and 502 b.

The tray conveying device 504 includes two supply paths 511a and 511b, two return paths 512a and 512b, and two recovery paths 514a and 514 b.

The supply path 511a extends in the left-right direction across the plurality of winding units 11 on the right side among the plurality of winding units 11, and is connected to the individual path 33 corresponding to the winding units 11. The supply path 511b is disposed on the left side of the supply path 511 a.

In addition, in the feeding paths 511a and 511b, the tray T is conveyed from the right side to the left side.

The return path 512a extends in the left-right direction on the rear side of the supply path 511 a. Both ends of the return path 512a are connected to both ends of the supply path 511 a. In the return path 512a, the tray T is conveyed from the left side to the right side. Further, a tray stopper 522a is provided in the center of the return path 512 a. The tray stopper 522a is the same as the tray stopper 35 (see fig. 1). Further, a jam eliminator 523 is provided in a portion of the return path 512a on the downstream side of the tray stopper 422 a. The clogging eliminator 523 is the same as the clogging eliminator 36 (see fig. 1). The tray conveying device 504 includes a connection path 515 for connecting a portion between the tray stopper 522a and the jam clearing device 523 in the return path 512a to the tray supply unit 502 a.

The return path 512b is located at the rear side of the supply path 511b and the left side of the return path 512a, and extends in the left-right direction. Both ends of the return path 512b are connected to both ends of the supply path 511 b. In the return path 512b, the tray T is conveyed from the left side to the right side. The upstream end of the return path 512b is connected to the tray supply unit 502 b.

Approximately half of the upstream side (right side) of the collection path 514a is positioned in front of the individual paths 33 connected to the supply path 511a, extends in the left-right direction, and is connected to the individual paths 33. In the recovery path 514a, the tray T is conveyed from the right side to the left side. Further, substantially half of the downstream side (left side) of the recovery path 514a is located on the front side of substantially half of the upstream side. The downstream end of the collecting path 514a is connected to the bobbin processing device 502.

The collection path 514b is located on the front side of the individual paths 33 connected to the supply path 511b, extends in the left-right direction, and is connected to the individual paths 33. In the recovery path 514b, the tray T is conveyed from the right side to the left side. The downstream end of the recovery path 514b is connected to the bobbin treatment device 502.

In embodiment 6, similarly to embodiment 1, the tray stopper 522a is caused to perform the feeding operation by control according to the flow shown in fig. 4 and 5. Further, similarly to embodiment 2, the tray stopper 522b is caused to perform the feeding operation by the control according to the flow shown in fig. 4 and 8.

However, in embodiment 6, the control of fig. 5 will be performed in the period U_NThe number of trays T internally discharged to the collection path 514a is set as A_N. In addition, will be in period U_NThe number of trays T supplied from the tray supply part 502B is B_N. In addition, will be in period U_NThe number of times of the cancelled feeding-out operation out of the feeding-out operations by the internal tray stopper 522a is set as C_N。

Although preferred embodiments 1 to 6 of the present invention have been described above, the present invention is not limited to the embodiments 1 to 6, and various modifications can be made within the scope of the claims.

In embodiment 1, when the tray T is supplied from the bobbin processing device within a certain cycle U and the feeding operation is scheduled after the supply of the tray T, the last feeding operation of the scheduled feeding operations is cancelled, but the present invention is not limited thereto. The carrying-out operation other than the last carrying-out operation among the predetermined carrying-out operations may be cancelled. The same applies to the feeding operation of the tray stopper 522a according to embodiments 3, 5 and 6.

Further, when the tray T is supplied from the bobbin handling device in a certain cycle U, even if the feeding operation is scheduled after the supply of the tray T, the feeding operation may not be canceled. Also in this case, it will be in period U_NNumber of times K of carrying out sending-out action of tray stopper_NIs set as (A)_N-1-B_N-1) The preparation method comprises the following steps.

In embodiment 1, the number of times the tray stopper 35 is caused to perform the feeding operation is set for each cycle U, but the present invention is not limited to this. The number of times of the feeding operation is set for each cycle U, and the feeding operation may be performed at a speed corresponding to a difference between the number of the trays T discharged from the plurality of winding units 11 and the number of the trays T directly supplied from the bobbin processing device 12 to the portion of the supply path or the return path 32 downstream of the tray stopper. The same applies to the feeding operation of the tray stopper 35 according to embodiment 3, the tray stopper 422a according to embodiment 5, and the tray stopper 522a according to embodiment 6.

In embodiment 2, the tray stopper 35 is caused to perform the feeding operation when the tray T is discharged from any one of the winding units 11, but the present invention is not limited to this. When the tray T is discharged, the tray stopper 35 may be caused to perform a process other than the feeding operation, and the feeding operation may be performed at a speed corresponding to a difference between the number of trays T discharged from the plurality of winding units 11 and the number of trays T directly supplied from the bobbin yarn processing device to a portion upstream of the tray stopper on the supply path or the return path. The same applies to the feeding operation of the tray stopper 35 according to embodiment 4 and the feeding operation of the tray stopper 522b according to embodiment 6.

In embodiments 1 to 6, the tray stopper is caused to perform the feeding operation at the maximum speed by the maximum feeding process until the tray T is detected by the tray sensor provided at the downstream end of the feeding path after the operation of the yarn winding machine 1 is started, but the present invention is not limited thereto. For example, instead of the maximum sending process, the following control may be performed: the tray stopper is caused to perform the feeding operation at a speed slower than the maximum speed but faster than the speed in the normal feeding process ("2 nd feeding speed" in the present invention). Alternatively, the tray stopper may be caused to perform the feeding operation by the normal feeding process even after the operation of the yarn winding machine 1 is started until the tray T is detected by the tray sensor provided at the downstream end of the supply path. That is, the process of S101 and S102 may be omitted in the flow of fig. 4, and the process may proceed to S103 when the operation of the yarn winding machine 1 is started.

In embodiment 1, when the bobbin processing device 12 is returned from the stopped state, the tray stopper is caused to perform the feeding operation by the normal feeding control, and the number of trays T to be discharged from the plurality of winding units 11 after that is counted. When the counted number of trays T exceeds the threshold value, the tray stopper is caused to perform the feeding operation by the maximum feeding control during a period from the time when the threshold value is exceeded to the time when the tray sensor 29 detects the tray T. But is not limited thereto.

For example, the tray stopper 35 may be caused to perform the feeding operation by the maximum feeding control during a period from the time when the bobbin processing device 12 is returned from the stopped state to the time when the tray sensor 29 detects the trays T, without depending on the number of trays T discharged from the plurality of winding units 11 after the bobbin processing device is returned from the stopped state.

Instead of the maximum sending process, the following control may be performed: the tray stopper is caused to perform the feeding operation at a speed slower than the maximum speed but faster than the speed in the normal feeding process ("2 nd feeding speed" in the present invention). Alternatively, the tray stopper may be caused to perform the feeding operation by the normal feeding process during a period after the bobbin preparation device is returned from the stopped state until the tray sensor detects the tray T, not depending on the number of trays T discharged from the plurality of winding units 11 after the bobbin processing device is returned from the stopped state.

Further, in the tray stopper 35 according to embodiment 2, the tray stopper 35 according to embodiment 4, and the tray stopper 522b according to embodiment 6, the feeding operation is performed once again for each Ma feeding operation, but the present invention is not limited thereto. The tray stopper may be caused to perform the feeding operation only when the tray T is discharged from a certain winding unit.

In embodiments 1 to 6, the MCU51, the plurality of winding control units 52, the bobbin processing control unit 53, the conveyance control unit 54, the delivery control unit 55, the communication-managing substrate 56, and the tray sensor 29 are connected to each other and can communicate with each other, but the present invention is not limited to this. At least the feeding control section 55 of these components may be capable of communicating with the plurality of winding control sections 52, bobbin processing control section 53, and tray sensor 29. Alternatively, for example, the MCU51 may be configured to be able to communicate with the plurality of winding control units 52, the bobbin processing control unit 53, the conveyance control unit 54, the delivery control unit 55, and the tray sensor 29, and the delivery control unit 55 may be configured to perform the above-described control by the MCU51 receiving signals from the plurality of winding control units 52, the bobbin processing control unit 53, and the tray sensor 29 and transmitting signals to the delivery control unit 55 based on the received signals.

The tray feeder is not limited to the structure of the tray stopper 35. The tray feeding device may be a device for carrying out the tray T by driving the conveyor 39 in a stopped state at a desired timing. The tray feeder may push out the tray T on the conveyor 39 in a stopped state at a desired timing.
