Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transporting full bobbins and empty bobbins between a spinning frame and a winder.

A condition for the effective operation of a system that automatically transfers bobbins between the spinning machine and the winder is to balance the yarn production capacity of the spinning machine and the yarn processing capacity of the winder, that is, to ensure that each machine operates without problems. If so, it would be possible to supply real bobbins to the spinning machine and the winder and return empty bobbins to the spinning machine without causing any waiting time in the spinning machine or winder.

Generally, the yarn production speed of a spinning machine is lower than the winding speed of a winder, and for example, if one 400-spindle spinning machine is paired with one 10-spindle winder, the production speeds of both can be balanced.

Therefore, it would be sufficient to directly connect a 10-spindle winder and a 400-spindle spinning frame, but in a factory with multiple spinning machines, the number of winders increases, and each winder requires a drive source and a feed device. etc., which is uneconomical.

For this reason, a plurality of spinning machines are associated with one winder. For example, four 400-spindle spinning machines and one 40-spindle winder are connected by an automatic conveyance path, and the pipe yarn produced by each spinning machine is supplied to one winder, and the air discharged from the winder is The bobbins are distributed and returned to multiple spinning machines.

On the other hand, as a means of conveying the pipe yarn doffed by the spinning machine, the pipe yarn is inserted into pegs on a rotating transport band that is laid along the spinning machine, and the transport band is rotated intermittently. At the same time, at the rear end of the spinning machine, the empty bobbin is fed onto the empty peg on the transport band, and the transport band rotates in only one direction. Therefore, there is a method of discharging the thread on the band and replacing the empty bobbin on the band. In this case, there is no problem because the supply of the yarn to the winder and the return of the empty bobbin to the spinning frame are balanced in one-to-one correspondence.

On the other hand, although it is similar in that the pipe yarn on the spinning machine side is transported by the transport band, the position where the empty bobbin is supplied onto the band may be on the same side as the pipe yarn delivery side.

For example, in the device shown in Japanese Patent Publication No. 43-29208, the conveyor belt along the spinning machine rotates back and forth, and after discharging all the pipe threads on the belt at the end, it rotates in the opposite direction, and during this intermittent rotation, This type feeds the empty bobbin onto the belt. In this case, the empty bobbin returned from the winder cannot be fed onto the belt while the yarn is being discharged.
An empty bobbin stocking device is required on the empty bobbin return path. A large stock space is required to store the empty bobbins for one spinning machine, 400 in the above example, and 200 for one side of the spinning machine. A slight taper is formed in order to increase the speed of bobbins, and if a large number of such empty bobbins are stored, the directionality will be lost and it will be extremely inconvenient to automatically convey the bobbins.

The present invention has been made in order to solve the above-mentioned disadvantages, and it connects the winder area and the spinning machine area having a plurality of spinning machines with a real bobbin conveyance line and an empty bobbin conveyance line, and Empty bobbins are returned to the spinning frame while the real bobbins doffed from other specified spinning machines other than the above-specified spinning frame are being delivered to the above-mentioned real bobbin conveyance line. .

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

1 and 2 show a layout in which four spinning machines SP1 to SP4 and one winder W are arranged. The spinning machines SP1 to SP4 are installed in parallel and constitute a spinning machine area A. In this embodiment, the winder area B is composed of one machine, but if the production capacity of each of the above-mentioned spinning machines SP1 to SP4 is doubled, the winder area B will be composed of two winders.

Between the spinning machine area A and the winder area B, there is one real bobbin conveying main line L1 and one empty bobbin conveying main line L2, which will be described later.
Formed by chute etc. The actual bobbin payout lines M1 to M4 provided in the spinning machines SP1 to SP4 merge with the actual bobbin transport main line L1.

Further, from the empty bobbin transport main line L2, there are branch lines N1R, N1L to return empty bobbins to the R and L machines of each spinning machine SP1 to SP4.
N4R and N4L are formed.

Therefore, the real bobbins on which the yarn produced by each spinning machine SP1 to SP4 is wound are transferred to the real bobbin discharging lines M1 to M1.
It is delivered from M4 onto the main line L1, transported, and supplied to the winder W area. Empty bobbins that have been rewound in the winder W and have no yarn layer are transported on the main transport line L2 and returned to the spinning machine area A, and are also returned to a predetermined spinning machine by a method to be described later. In this way, the bobbin is circulated and conveyed between the spinning frame and the winder, and is conveyed in a closed loop as a medium for sequentially transferring the yarn produced by the spinning frame to the winder.

An example of a spinning machine SP and a winder W are schematically shown in FIGS. 2 to 4. In addition, spinning machines SP1~SP
4 are collectively referred to as SP. In Figures 2 and 3, the spinning machine SP has an R stand SPR and an L stand SPL arranged back to back to form one spinning machine. 2 is arranged so as to be rotatable in forward and reverse directions.

That is, the transport bands 1 and 2 have bobbin insertion pegs 3 planted at the same pitch as the spindle pitch of a spinning machine, and both bands 1 and 2 share a common drive source 4 and drive shaft 5. Interlock.
The transport hands 1, 2 have horizontal parts 1a, 2a along the machine base and inclined parts 1b, 2b at the ends of the machine base, and are connected to a chute 6 (to be described later) from the upper ends of the inclined parts 1b, 2b on both bands. Two real bobbins are dispensed at the same time. Further, on the delivery side of the transport band, an empty bobbin supply station 7 is provided for supplying empty bobbins onto the band from which real bobbins have been delivered. The station 7 includes an empty bobbin box 8 that can reserve a plurality of empty bobbins returned from the winder, and an empty bobbin cutting section that cuts out the empty bobbins one by one from the box 8 and inserts them into pegs on the transport band. 9. The arrow 10 in FIG. 3 is the direction of rotation of the transport bands 1 and 2 when the actual bobbin is paid out, and the arrow 11
is the direction of rotation when feeding an empty bobbin.

An example of a winder is shown in FIGS. 2 and 4, and the winder W is composed of a plurality of winding units 12 shown in FIG.
is transported on a belt 15 rotating along one side of the winder while being inserted into a carrier 14 having a bobbin insertion peg 13 formed on a disc body, and is placed in an empty bobbin waiting groove of the winding unit 12. is automatically supplied to certain units. That is, the intake port 21 is placed in the standby groove 20 formed by the guide plates 16, 17, 18 and the lower rotating disk 19.
When a predetermined number of real bobbins are stored, subsequent real bobbins are no longer allowed to enter the unit, and are transferred to the next empty winding unit from the delivery port 22. It will be sent out.

Furthermore, when the actual bobbin FB at the rewinding position 23 of the winding unit 12 has finished rewinding and becomes an empty bobbin, the ejection lever 24 is activated by a command from the unit.
The empty bobbin is discharged onto the empty bobbin conveying belt 25 while being inserted into the carrier 14, and is conveyed to the next process as the belt 25 rotates. In FIG. 2, 26 is a station for extracting the empty bobbins transferred by the carrier, and the empty bobbins removed by the bobbin gripping tool that rotates up and down are transferred to the spinning machine side via the empty bobbin conveying line L2. It will be returned and transferred to. Furthermore, the carrier, which has become empty after the empty bobbin has been extracted, is transferred to the actual bobbin supply station 27, where it receives the actual bobbin supply, passes through the yarn end take-out station 28, and is then supplied to each winding unit of the winder as shown in Fig. 4. be done.

In addition to the above-mentioned types, the winder may be of any other type, such as a type in which each winding unit has a real bobbin storage magazine on the front and the real bobbins are automatically supplied to the magazine by a conveyor or a trolley. be.

Next, each part constituting the bobbin conveyance line will be explained.

FIGS. 5 and 6 show the guide chute and the inclined delivery conveyor for real bobbins delivered from the transport bands on both sides of each of the spinning machines SP1 to SP4. That is, the above transport bands 1 and 2
The intake ports 31 and 32 of the chute 29 and 30 are provided at the same distance as the distance between the bands 1 and 2 following the upper end of the inclined portion of the chute, and the lower end openings 33 and 34 of the chute are arranged one pitch in the vertical direction of the dispensing conveyor M. It is installed in a certain position. Payout conveyor M is chute 2
It rotates diagonally upward through approximately the center of the intake ports 31, 32 of 9, 30, that is, the center of the frames 35, 36, and the actual bobbin lifting pin or plate 37 is placed on the upper surface of the conveyor M at an even pitch. They are fixed with at least the length interval of the actual bobbin. Further, a direction regulating plate 38 for the real bobbin is fixed near the chute entrance, and the real bobbin is inserted into the chute 29 with the head 39 in contact with the regulating plate 38 and the butt 40 facing down.
Fall within 30. 41 and 42 are photoelectric sensors,
By blocking the light penetrating both chute when the real bobbin falls, it is determined that normally two real bobbins are placed on the delivery conveyor, but in some cases one real bobbin is placed on the delivery conveyor, and the conveyor M is Generates a signal to rotate the stroke. One stroke means the distance C in Figure 5, which is at least the length of two real bobbins.
The distance is longer than the length of FB1 and FB2. In addition,
The upper plates 29a and 30a of the lower end openings of the chute 29 and 30 in FIG. It is easy to take out.

Therefore, the real bobbins to be delivered onto the delivery conveyor M are intermittently transferred two by two towards the upper main transport line L1. In this way, each spinning machine
The actual bobbin FB dispensed from SP1 to SP4 is the first,
The real bobbins are transported in the same direction on the real bobbin transport main line L1 shown in FIG. Although the real bobbin supply device 27 is not limited to a particular type, for example, a device as shown in FIG. 7 is applicable.

That is, the real bobbin supply device 27 is composed of a hopper 46 for storing a predetermined number of real bobbins, a cutting device 47 following the opening at the lower end of the hopper 46, and a guide chute 48 for guiding the bobbin onto a bobbin carrier waiting below. Every time the carrier arrives at the bobbin receiving position, the cutting device 47 is driven for one cycle to cut out the actual bobbin FB1. Feelers 49, 50, 51 are arranged as appropriate along the zigzag stock passage in the hopper 46,
Detects the presence or absence of a bobbin at the filler position. For example, when the feeler 49 detects that there is no bobbin, the winder side unloading device is stopped and put on standby, and when the feeler 51 runs out of bobbins and the number of bobbins decreases further, a real bobbin request signal is sent to the spinning machine, and the real bobbin conveyance line is driven. The real bobbin is fed to the hopper, and when the real bobbin is fed to the feeler 51, a requested stop occurs. Further, when a real bobbin is requested and no real bobbin is sent for a long time, that is, when the real bobbin reaches the position of the feeler 50, a check signal is issued for the delivery conveyor on the spinning machine side and the conveyance path on the other spinning machine side.

Next, the line L2 for returning empty bobbins from the winder side to the spinning machine side will be explained.

In FIG. 2, the empty bobbins discharged from each winding unit 12 of the winder W are transported to the bobbin extracting station 26 while being inserted into a carrier, and at this station are moved by the bobbin gripping and releasing member that moves up and down as described above. The empty bobbins extracted from the carrier are transferred by the lifting conveyor 52 to the empty bobbin transport main line L2 installed above.

As shown in Figure 1, the main line L2 is a line consisting of a belt conveyor extending to the spinning machine area, and branch line N1 is formed at each spinning machine SP1 to SP4.
R to N4L are connected via a movable guide which will be described later.

The connection part of the above branch line and main line is connected to the 8th
This will be explained in detail in Figures 1 to 11. 8 and 9 representatively show the connection parts of the branch lines N1R to N4R, and FIGS. 10 and 11 show the terminal branch line N4.
The L connections are shown.

In FIGS. 8 and 9, the main line L2 is composed of a conveyor 53 and guide plates 54 and 55 on both sides, and a notch 56 is formed in the guide plate at the branch line N1R position. The branch line N1R is composed of a take-in chute 58 that slopes downward and has a curved portion 57, and a guide chute 59 that extends from the chute 58 to the bobbin stocker position of the spinning frame. At the above connection part, there is a movable guide 6 that moves to two positions by the rotary solenoid SO1R.
0 is set. That is, when the movable guide 60 is at the solid line position 60, the empty bobbin EB on the line L2 passes through the chute 57 without being taken in, and is taken into the chute 57 only when the guide is at the two-dot chain line position 60a.

The opening and closing of the movable guide 60 is operated by a sensor PH044 disposed immediately in front of the guide 60 and an output from a control device that inputs and processes signals from the sensor. Furthermore, when the movable guide 60 pivots from the solid line position 60 to the two-dot chain line position 60a, it also has the role of preventing empty bobbins on the conveyor from being pinched between the guide plate 54 and the movable guide 60, and the sensor PH044 After an empty bobbin passes through the position, driving of the rotary solenoid is blocked until the next empty bobbin arrives.

Figures 10 and 11 show a branch line N4L at the final end of the spinning machine area, and since there is no empty bobbin that passes through the main line beyond the branch line N4L, it branches to the main line L2 without providing a movable guide. The connection portion of line N4L is always in a readable state. That is, one side plate 62 of the intake chute 61 crosses the line L2 and the guide plate 5
It is formed to reach up to 4. In some cases, a movable guide may be provided at the connection part of the branch line N4L in the same way as the branch line N1R, so that when a surplus empty bobbin occurs, or in combination with a bobbin with remaining thread detection device, the remaining thread can be removed. It is also possible to discharge the attached bobbin to the outside of the system.

Bobbin boxes 8 shown in the 12th to 14th figures are arranged at the lower end of each of the branch lines N1R to N4L. As shown in FIG. 2, the box 8 is provided for each of the R stand and the L stand of the spinning machine SP, and is provided at the end on the actual bobbin discharge side. Empty bobbin box 8 above
is a box body having a width d approximately equal to the length of an empty bobbin, and is formed of four sides and a bottom surface, the top surface is an opening for receiving the bobbin, and the above-mentioned branch line N
Connect to the lower end of 1R to N4L. Further, a passing window 64 through which one bobbin can pass is formed in the center of the bottom surface 63, and an empty bobbin is cut out below the passing window 64 and inserted into a peg on the transport band. A mounting device 9 is installed.

Inside the box 8, inclined guide plates 65 and 66 are fixed to prevent layer collapse due to the difference in diameter between the butt and head portions of the bobbins when stacking the tapered bobbins. That is, as shown in FIGS. 13 and 14, the area of the trapezoidal portion 68 formed by the guide plates 65 and 66 and indicated by the diagonal line upward to the left of the side plate 67 on the bobbin head 39 side is S1, and the area on the bobbin bottom portion 40 side is The area of the trapezoidal portion 70 formed by the guide plates 65 and 66 and indicated by the diagonal line upward to the right of the side plate 69 is defined as S2. On the other hand, if the cross-sectional area perpendicular to the bobbin axis at the end of the bobbin head is a, and the area of the bottom end of the bobbin is b, then the inclined guide plates 65, 66 are arranged so that the relationship S1:a=S2:b holds.
By attaching the blank bobbins, when the empty bobbins are stacked, the tapered surfaces of the bobbins are kept in close contact with each other and the bobbins are housed in an orderly manner without losing their orientation.
Reference numerals 75 and 76 serve as inclined surfaces for guiding the empty bobbin to the passage window 64, and are formed by bending the above-mentioned inclined guide plates 65 and 66.

Furthermore, inside the box 8, guide pieces 71 are fixed to flexible bands 72, 73 such as belts in a zigzag manner to face each other in a zigzag manner for alleviating the impact of the empty bobbin falling from the chute and regulating the direction. The bands 72, 73 are suspended from the upper end of the box, and are prevented from expanding outward by leaf springs 74, 74. It should be noted that the box 8 applied to carry out the present invention does not require a space to accommodate the bobbins for one side of the spinning machine, and a space capable of accommodating about 20 to 30% of the bobbins is sufficient.

The operation of the bobbin conveying device configured as above will be explained next. FIG. 15 shows a schematic time chart. That is, in this embodiment, one winder is associated with four spinning machines SP1 to SP4, and the spinning time of one spinning machine, that is, the time required to wind a predetermined amount of spun yarn onto an empty bobbin, is 1. Let the doff time be T, and the time obtained by dividing the time T into four equal parts is t1~t
Set it to 4. That is, t1 = t2 = t3 = t4 = 1/4 · T, the moving speed of transport bands 1 and 2 on the spinning machine side is related to time t, and is doffed by one spinning machine within the time t. Balance is maintained so that all of the empty bobbins are dispensed and the supply of empty bobbins is completed within time t.

Immediately after the spinning time T1 is completed in the spinning frame SP1, doffing AD1 is performed, and the empty bobbin on the transport band waiting along the spinning frame is exchanged with the real bobbin on the spindle, and spinning operation T1' continues. will be held. Further, the actual bobbin placed on the transport band enters a payout operation to be supplied to the winder. That is, all the real bobbins of the spinning machine SP1 are delivered onto the real bobbin transport main line L1 within time t1. During this time, spinning machine SP
The first transport band only takes out real bobbins and does not supply empty bobbins. Furthermore, empty bobbins returned from the winder during the unloading of real bobbins are not returned to the spinning machine only at the beginning when the device is engaged, but are discharged to the outside of the bobbin conveyance path connecting the spinning machine area and the winder. In other words, the actual bobbin is being paid out A1
When the empty bobbin discharged from the winder is extracted from the carrier at the bobbin extraction station 26 in FIG. 2, it is not transferred to the conveyance line 52 but is stored in a bobbin box located near the station.

Next, spinning machine SP2 doffs AD2 after spinning time T2.
When this is done, the actual bobbin payout A2 is started in the same manner as described above. That is, at the start of time t2, the return of the empty bobbin to the spinning machine SP1 from which the delivery of the real bobbin has been completed is started. Spinning machine SP1 within time t2
As soon as the empty bobbin is returned to the spinning machine SP2,
The actual bobbin dispensing from the actual bobbin is completed. Further spinning machine
The return of the empty bobbin to SP2 starts almost at the same time as the start of the actual bobbin payout A3 after the doffing of another spinning machine, such as the spinning machine SP3, which has received doffing. Similarly, empty bobbins are returned to a specified spinning frame at the same time as the spinning machines other than the specified spinning frame start discharging full bobbins.
That is, while the empty bobbin is being inserted into the peg on the transport band in the spinning machine, the empty bobbin is returned from the winder to the spinning machine.

In other words, the actual bobbin conveyance order is determined according to the order in which doffing completion signals are generated from multiple spinning machines, and the actual bobbin produced by the leading spinning frame, that is, the spinning machine that first issued the doffing completion signal, is After all the bobbins are transported to the winder, the next spinning machine produces a real bobbin, and the empty bobbins wound by the winder are returned to the spinning machine that has finished discharging the real bobbins.

In addition, as shown in Figures 5 and 6, two real bobbins are paid out from each of the spinning machines at the same time, one each from the R and L machines, and two bobbins are delivered from the shoot 2.
The real bobbins FB1 and FB2 are placed separately on two positions on the inclined conveyor M via the conveyor belts 9 and 30, and as the conveyor M rotates, the real bobbins FB1 and FB2 are transferred upward and transferred to the conveyance main line L1. The bobbin is transported to the real bobbin supply device 27 on the winder side shown in the figure.

Additionally, empty bobbins can be returned to the designated spinning machine.
One by one is returned alternately to the R and L bobbin boxes. That is, in FIG. 16, for example, when an empty bobbin is returned to the spinning machine SP1, the empty bobbin is transferred on the empty bobbin transport main line L2.
FB1 is branch line N1R, N1 of spinning machine SP1
By controlling movable guides 60R and 60L provided at the L connection part, they are alternately transferred to branch lines N1R and N1L. That is, at the start of returning empty bobbins to the spinning machine SP1, the movable guide 60L of the branch line N1L on the downstream side of the main line L2 is positioned at the solid line position by the action of the rotary solenoid SO1L. Continue to maintain the solid line position until the return of the empty bobbin to the spinning machine is completed. Therefore, if the movable guide 60R on the R stand side, that is, on the upstream side of the main line L2, is opened and closed every time an empty bobbin passes, the empty bobbins are alternately transferred to the branch lines N1R and N1L.

The above control is performed by sensor PH04 placed just before the branch road.
4. This is done using the ON/OFF signal of PH045, that is, the empty bobbin presence/absence signal.

The above-mentioned alternate transfer of empty bobbins is carried out, for example, by a sequence circuit shown in FIG. 17. Now, when the delivery of the real bobbin of the spinning frame SP1 is completed and the reversal of the transport band for receiving the empty bobbin of the spinning machine SP1 is started at the same time as the delivery of the real bobbin from the other spinning machines is started, the reversal signal is activated. Input from the spinning machine side to the control unit, contact RA1 for the spinning machine SP1 in Fig. 17
010 closes Relay RA6 for solenoid SO1L
1 closes, the downstream movable guide 60L in FIG. 16 moves to the solid line position, and the a contact RA of the relay RA61 is closed.
61 closes to form a self-holding circuit, and the movable guide 6
0L maintains the position protruding into the main line L2 until the empty bobbin is returned.

In this state, when the empty bobbin FB1 reaches the sensor PH044 position, the b contact PH0 for the solenoid SO1R
44 closes, relay RA60 is energized, rotary solenoid SO1R acts, moves to the position indicated by the two-dot chain line in Fig. 16, and is self-held by a contact RA60.
Even if the contact KR34 of the keep relay KR34 is opened, the movable guide remains closed even after the empty bobbin FB1 passes the sensor PH044 position, and the empty bobbin FB
1 guides the transfer to chute N1R for R unit.

When empty bobbin FB1 passes sensor PH044 position, a contact PH044 closes and relay RA101 is activated.
5 is excited, and the a contact RA1015 is closed. In this state, when the next empty bobbin reaches the sensor PH044 position, the b contact PH044 for relay RA1016
is closed, relay RA1016 is energized, and the b contact
RA1016 is opened, relay RA60 is de-energized, solenoid SO1R returns to the solid line position in FIG. 16, and the next empty bobbin is not transferred to branch line N1R, but is transferred through main line L2 and then transferred to branch line N1L. At this time sensor PH04
When the next empty bobbin reaches the sensor PH044 position, the solenoid SO1R is energized again in the same manner as above. The movable guide 60R protrudes.

In this way, the rotary solenoid SO1R opens and closes every time an empty bobbin passes, and the empty bobbins transferred on the main line L2 are alternately distributed to the branch lines N1R and N1L.

The above empty bobbins are distributed to spinning machines SP2 and SP3.
The same is true for spinning machine SP4, but since there is no rotary solenoid for L machine,
The movable guide on the R stand side performs opening and closing operations in exactly the same manner except that there is no circuit corresponding to the line of relay RA61 for SO1L in FIG. 17.

The main parts of the sequence circuit from doffing to empty bobbin receiving in each of the spinning machines SP1 to SP4 are shown in FIGS. 18 to 20.

In FIG. 18, for example, when doffing is completed in the spinning machine SP1, the contact O is closed, registration of actual bobbin transport is accepted, and an acceptance signal is input to the shift register corresponding to the spinning machine SP1. That is, when the a-contact O is closed by the doffing completion signal issued from the spinning machine SP1, the relay RA400 is energized, and the keep relay KR is activated via the a-contact RA400.
000 is set and contact KR000 in Fig. 19 is set.
is closed, and timer relay TIM000 is energized.
Furthermore, contact RA410 is closed via contact TIM000 relay RA410, and the actual bobbin transfer registration acceptance signal is input to the shift register MOV〓01KR
001). When doffing completion signals are output from each spinning machine, they are input in the time order of doffing completion, so for example, if the real bobbin transfer registration acceptance signal of spinning machine SP1 is input via keep relay KR000. Contact point KR000 of the reception circuit on the spinning machine SP2 side
is open, so even if contact KR001 is closed by the doffing completion signal of spinning machine SP2, relay T1M00 is
1 is not energized, and when the keep relay WR000 is reset after the transfer of the real bobbin of the spinning machine SP1 is completed, the contact KR000 closes, so if the doffing completion signal is output from the spinning machine SP2 at this time, the contact will close. Since KR001 is closed, spinning machine SP
The real bobbin conveyance registration acceptance signal of No. 2 is input to the shift register, and then the real bobbin payout of the spinning machine SP2 is started. Therefore, actual bobbins are not dispensed from two spinning machines, for example SP1 and SP2, at the same time.

Furthermore, in FIG. 20, in the spinning machine SP1, the contact KR30, which is capable of accepting an empty bobbin, closes when the payout of a real bobbin is completed. When the transport band starts to rotate in the reverse direction, that is, when the empty bobbin previously stored in the bobbin box starts to be inserted into the peg on the transport band, the a contact 4 in FIG. 20 closes. Relay RA101
0 is energized, and the contact RA10 in FIG.
10 is closed and the empty bobbin distribution operation is performed. When the supply of the empty bobbin onto the transport band is completed, the keep relay KR30 shown in Fig. 20 is reset, and the b contact KR30 is closed and the timer relay T is activated.
1M005 opens the b contact T1M005 and the relay RA1010 becomes de-energized, and the contact shown in Fig. 17
RA1010 opens, the distribution of empty bobbins to the spinning frame SP1 is stopped, and preparations are made for the next designated spinning frame to receive empty bobbins.

The circuits shown in Figures 17 to 20 are for spinning machine SP.
1 is shown, and similarly, other spinning machines are similarly provided following each circuit.

FIG. 21 shows a flowchart of the operation of discharging the actual bobbin and supplying the empty bobbin.

That is, the control circuit is constructed using the number of shift register stages corresponding to the number of spinning machines directly connected to the winder.

When receiving a signal from the spinning frame indicating that the actual bobbin can be transported (step), the signal from the leading spinning frame is shifted to the last stage of the shift register in order (step).
Control the conveyance of the real bobbin in the spinning machine using the bit position of the signal in the final stage (step). When the conveyance is completed (step), remember that it has ended (step) and reset the final stage of the shift register. (step).
After the reset, the contents of the shift register one stage before the final stage of the shift register are shifted to the final stage (step), and the actual bobbin transfer to the next spinning machine begins (step).

On the other hand, the memory of the end of conveyance of the real bobbin of the leading spinning machine, that is,
Based on the empty bobbin return possible memory and the empty bobbin acceptance signal (step) from the spinning machine, the empty bobbins are sorted and returned one by one to the left and right to the leading spinning machine (step).

Thereafter, the real bobbins of a plurality of spinning machines are transported and the empty bobbins are returned in the same manner.

As described above, in the method of the present invention, a winder area and a spinning machine area having a plurality of spinning machines are connected by a real bobbin conveying line and an empty bobbin conveying line,
Empty bobbins are returned to the specified spinning frame in the above-mentioned spinning machine area, while the real bobbins doffed from the specified spinning machines other than the above-mentioned spinning machine are being delivered to the above-mentioned real bobbin conveyance line. Due to the structure of the spinning machine, if it is impossible to return an empty bobbin to the spinning machine while a real bobbin is being unloaded,
Even if possible, it is particularly effective when empty bobbin stock devices for the number of spindles of a spinning machine are required. In other words, when returning an empty bobbin to a certain spinning machine, it is returned from the winder to the spinning machine while the empty bobbin is being supplied to the transport band of the spinning machine, so the returned empty bobbin can be placed on the transport band at any time. Since the bobbin is supplied to the winder, there is no need to provide an empty bobbin stock device that takes up a large space, and there is no need to make any major modifications to the existing spinning machine, making it possible to automatically transport the bobbin to and from the winder.

In addition, the feeding position of empty bobbins to the spinning machine can be installed on the same side as the real bobbin discharging side of the spinning machine. The conveyance line can be significantly shortened.
