Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bobbin management system in a textile machine having a plurality of yarn processing units.

For example, in an automatic winder, a plurality of winding units are arranged in parallel to form one automatic winder, and each winding unit has a real bobbin having a layer of yarn to be wound supported by a peg, and a real bobbin is supported on the peg. The thread pulled out from the real bobbin is traversed and wound onto the winding package in a predetermined amount and in a shape suitable for subsequent processing.

In addition, the amount of thread wound on real bobbins wound by a spinning machine, especially a ring spinning machine, is small due to the nature of the machine. Therefore, when rewinding with a winder, the threads of multiple real bobbins are wound while being knotted, and the threads are wound in a subsequent process. The purpose is to obtain a package with a shape suitable for use or a large amount of yarn.

Therefore, it is necessary to supply a number of real bobbins to obtain one package. At this time, in order to increase the operating rate of the winder, it is necessary to always have a real bobbin near the unit, and to supply the prepared real bobbin as soon as the real bobbin being wound becomes empty.

For this reason, in a fixed unit type winder, a magazine for storing the real bobbin is placed at a specific position in each unit, and it is necessary to check whether all the thread on the real bobbin being wound by the unit is wound up, whether there is a mistake in thread splicing, or when the lead thread end is If the yarn is not caught in the package, the empty bobbin or the bobbin with remaining yarn is discharged from the unit, and a new real bobbin is supplied from the magazine.

In such a case, an operator may supply bobbins to a real bobbin storage section such as a magazine provided in each unit while looking around the unit, or a filler may be installed in each magazine to ensure that there are no real bobbins left or the number is less than a certain number. When this happens, a real bobbin request signal must be issued and a real bobbin must be supplied automatically or manually.

In other words, the supply and non-supply of actual bobbins is managed for each winding unit, making bobbin management extremely complicated and inefficient for machines where one winder consists of dozens of units. It is.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to combine one winder, that is, multiple units as one unit, and to supply actual bobbins to one winder without having to supply actual bobbins at the request of each unit. The number of empty bobbins or remaining yarn discharged from the winder is counted, and actual bobbins equal to the counted number are supplied to the winder, thereby facilitating bobbin management.

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

Figure 1 shows a winding unit to which the system of the present invention is applied.
A spindle 2 and a suction pipe 3 are installed between them, and a winding unit 4 is rotatably supported on the spindle 2. While the automatic winder is in operation, the unit 4 is also placed on the suction pipe 3 and fixed as appropriate. be done. Note that the suction pipe 3 is connected to a blower (not shown), and a suction air current is constantly applied thereto.

In winding the yarn from the actual bobbin 5 to the package 6 in the winding unit, the yarn pulled out from the actual bobbin 5 on the tray 7 passes through the balloon breaker 8 and the yarn guide 9, and then is given an appropriate tension by the tensor 10. It passes through a slab catcher 11 and is wound onto a rotating package by a winding drum 12.

At this time, when the slab catcher 11 detects a slab in the yarn, a cutter installed near the slab catcher 11 operates to cut the running yarn Y, and while winding is stopped, the first The suction arm 13 operates to guide the thread on the package 6 side, and the second suction arm 14 guides the thread on the real bobbin 5 side to the knotter 15 installed at a position away from the normal thread travel path Y. After the thread is tied at step 15, winding is started again.

A large number of such winding units 4 are arranged side by side in a direction perpendicular to the plane of the paper in FIG. 1 to constitute one automatic winder.

Assuming that the thread running path side of the winding unit 4 is the front side of the unit, a conveyor belt 16 for supplying actual bobbins that runs along the unit is provided below the back of the unit on the opposite side, and a conveyor belt 16 for supplying actual bobbins that runs along the unit is provided at the lower front of the unit. A conveyor belt 17 for carrying out empty bobbins is installed along the line, and a pipe yarn transfer passage 18 is formed between the conveyor belts 16 and 17.

The actual bobbin 5 transported by the conveyor belt is inserted into the tray 7 shown in FIGS. 2 and 3 and transported.

That is, the tray 7 is formed by integrally molding or fixing a disc-shaped base 19 placed on a conveyor, a disc-shaped base 20 formed on the upper surface of the base 19, and a peg 21 standing upright on the base. The inner bottom surface is an opening 22, which communicates with the hollow interior of the peg 22,
A hole 24 for blowing out air is bored in the slope of the chevron-shaped top 23 of the peg 22.

Therefore, the actual bobbin 5 is inserted into the peg 21 of the tray 7 and conveyed with its lower surface supported by the stand 24. The yarn end Y1 pulled out from the actual bobbin side when tying the yarn is inserted into the center hole 26 of the empty bobbin 25 and transferred in a suspended state as shown in the third figure.

When tying the thread, the nozzle 43 at a predetermined position of the unit
Air is blown out from inside the tray 7 to the Pezgu 2.
When the yarn end Y1 is ejected from the hole 24 of No. 1 into the center hole 26 of the empty bobbin, the hanging yarn end Y1 jumps upward from the hole 26 and is suctioned and held by the waiting suction arm.

4 and 5, the actual bobbin supply device 27 installed in each winding unit will be described in detail.

That is, first, second, and third guide plates 30, 31, and 32, which form a tray passage, are fixed to each unit between the conveyor belt 28 for supplying a real bobbin and the conveyor belt 29 for discharging an empty bobbin.

That is, the passages 33, 34, 35, 36 formed by the guide plates 30, 31, 32 guide the base 20 of the tray 7, and the bottom surface of the base 19 of the tray is at a distance between the upper surface of the conveyor and the guides 31, 32. h
It is supported by the upper surface of a disk body 37 which freely rotates at a lower part thereof.

The disk body 37 is pivotally supported 39 by a bracket 38 fixed to the side surface of the unit 4, and the shaft 39 is fixed at a slight inclination with respect to the horizontal plane.

The bent portions 40 of the passages 35 and 36 are the thread pulling positions of the actual bobbin, and a flat plate 41 fixed to the bracket is fixed to the lower surface of the passage 36 in an inclined manner so as to form the same plane as the circular plate 37. Note that disk 3
A gap 42 is formed between 7 and the flat plate 41, which serves as a thread pulling position for the actual bobbin, and serves as a passage hole for air ejected from an air ejection nozzle 43 disposed below.

Further, the disk 37 is configured such that an annular band portion 46 formed by an outer periphery 44 and an imaginary arc 45 spaced a certain distance S from the outer periphery comes into pressure contact with the side upper surface of the conveyor belt 28 when the disk rotates. The disk 3 is moved by the running force of the conveyor belt 28.
7 rotates, and therefore the conveyor belt 28 functions as a driving source for the disk 37 as well as transporting the tube yarn.

Further, when a predetermined number of trays are accommodated on the guide surface 47 and the passage 35 that guide the trays on the conveyor 28 onto the disk 37, the first guide 30 discharges subsequent trays onto the conveyor 28 again. It has a guide surface 48.

Note that the width of each of the passages 33, 34, 35, and 36 is l.
is regulated to be approximately the same as or slightly larger than the diameter d of the base portion 20 of the tray 7, and the height h is regulated to be approximately the same or slightly larger than the thickness t of the base 19 of the tray 7 to prevent the tray from falling over. A passageway is formed that allows for smooth conveyance.

Furthermore, a rotating lever 49 for positioning and discharging the bobbin is pivotally supported by the fixed flat plate 41.
pivots around the axis 50 between a solid line position 49 and a two-dot chain line position 49a in FIG. The shaft 50 of the lever 49 is also inclined at the same angle as the shaft 39 of the disc 37, and the lever 49 rotates in a plane parallel to the disc 37 and comes into contact with the base 20 of the tray 7 to position the tray. Discharge.

That is, when the hook portion 51 of the lever 49 is in the solid line position, it projects onto the passage 36 and contacts the base of the tray to position the real bobbin 5 at the winding position. A guide surface 52 following the hook part is a guide surface for pushing out the tray at the winding position and discharging it along the passage 36, and a guide surface 53 formed by a part of an arc centered on the shaft 50 is a guide surface for pushing out the tray at the winding position and discharging it along the passage 36. This is a guide surface for preventing the transfer of a tray with a real bobbin inserted therein.

The swing lever 49 is driven by the empty bobbin discharge command from the winding unit operating the lever 54 shown in the fifth figure via a rod (not shown) and rotating the shaft 50 via the connecting rod 55. It will be done.

Further, a swingable balloon guide 56 is pivotally supported 57 above the lever 49. The balloon guide 56 has a curved plate 59 fixed to the tip of an arm 58, and is biased clockwise by a spring 60 in the clockwise direction in FIG. 4 during the winding operation of the unit. It is positioned at the solid line position in FIG. 5, so that the balloon of the drawn yarn of the real bobbin 5 does not come into contact with the next real bobbin waiting in the passage 35.

The balloon guide 56 is positioned by the side surface of the spring-biased arm 58 coming into contact with the stopper 61 at the end of the empty bobbin discharge lever 49. Therefore, when the lever 49 pivots to a position 49a shown in two-dot chain line in FIG. It turns to a position where it abuts the stopper 61a at the chain line position, the curved plate 59 retreats from the path 35, and the tray 7b with the real bobbin inserted therein is transferred to the yarn supply position 40.

In the above-mentioned real bobbin supply device, the finished spinning real bobbins 5 are inserted into the tray 7 which is transferred on the conveyor belt 28, and the real bobbins 5 shown in the fourth figure provided corresponding to the winding unit are inserted into the tray 7 which is transferred on the conveyor belt 28. When it comes into contact with the guide 30, the tray 7 is transferred along the path 33 and the bottom surface of the base is transferred onto the disk 37,
By rotating the disk 37 in the direction of arrow 62, the tray 7
is transported along the passage 35 and stopped by being stopped by a hook 51 at a bend in the passage. In this way,
When a predetermined amount (3 times as much in FIG. 4) of trays 7 having actual bobbins that are transferred on the conveyor belt 28 in the direction of the arrow 63 are stored, the subsequent trays 7b are transferred to the passage 3.
4 and is prevented from coming into contact with the base 19 of the tray 7C,
Since the contact surface with the belt 28 is large, and therefore a large frictional force acts, the tray 7d at the entrance of the passage 35 advances along the guide surface 48 and is transferred by the conveyor belt 28 to the next winding unit.

Therefore, if the conveyor belt 28 is kept circulating, a predetermined number of actual bobbins will be supplied to all units.

The process of pulling out the thread from the real bobbin 5 positioned at the fixed position in FIG. 5 and starting winding is performed roughly in the following order.

That is, an air jet nozzle 43 is arranged below the tray 7a in a fixed position, and the air jetted from the nozzle 43 is jetted from the hole bored in the peg of the tray to the center hole of the actual bobbin 5 as described above. The yarn end Y1 hanging down in the bobbin center hole 26 is blown up and the upper end of the yarn end is blown up through the cylindrical balloon breaker 8 above.

On the other hand, from the winding unit side, the second suction arm 14 is located at the position 14a shown in two-dot chain line in FIG.
The suction arm 14a removes the yarn ends that are nearby or are blown up through the balloon breaker 8.
attracts and holds. The suction arm 14 that has suctioned the yarn end on the bobbin side rotates counterclockwise around the shaft 14b, and the first suction arm 13a that has suctioned and held the yarn end on the package cage 6 side rotates around the shaft 13b. The thread is turned clockwise, the ends of the thread are crossed and introduced into the knotter 15, the thread is tied, and then normal winding is started.

When the actual bobbin at the thread supply position runs out of thread, the detection device on the unit side operates and issues a command to discharge the empty bobbin, and the rod 55 for operating the swing lever 49 shown in Fig. The tray 7a containing the empty bobbin is discharged onto the conveyor belt 29 for transferring empty bobbins as shown in the first figure by turning to the position 49a shown in two-dot chain line, and as the turning lever 49 returns to its original position, the tray 7a containing the empty bobbin is transferred to the next real bobbin. The tray 7b moves along the path 35 and is positioned at a predetermined yarn supply position 40.

FIG. 6 shows a bobbin management system for winder A, which is constructed by arranging a plurality of winding units as described above in parallel.

That is, for one winder A, a real bobbin supply conveyor 28 is provided on one side along the units AI to An, and an empty bobbin conveyor 29 is provided on one side along the units AI to An.
is provided on the other side of the unit, and the conveyors 28 and 29 are directly connected to a spinning machine (not shown), and the spinning fruit bobbin is inserted into a tray and conveyed on the supply conveyor, and the wine Empty bobbins discharged from the dyeing unit are again conveyed to the spinning machine.

On the input side of the winder A of the supply conveyor 28, there is disposed a bobbin preparation station having a pull-out device T for pulling out the thread end of the actual bobbin. That is, the bobbin applied to this system is supplied to the winding unit with the end of the yarn inserted into the center hole 26 of the bobbin and hanging down, as shown in FIGS. A pick-up device T is arranged for unwinding the tail thread of the bobbin and inserting the thread end of a certain length into the bobbin center hole.

Further, a photoelectric switch PS1 is provided between the winder A and the winder T, and the photoelectric switch
PS1 checks the number of real bobbins supplied from the pick-up device T to the winder A. Every time one real bobbin passes, an addition signal is output to the counter CO, and the counter adds +1.
Further, a photoelectric switch PS2 is provided on the empty bobbin conveyor 29 side to check the number of empty bobbins being carried out from the winder A.
PS1, PS2 and counter CO are connected, and counter CO is connected to output device T and micro switch MS via relay RA.

An embodiment of the pick-out device T is shown in FIG.

That is, the tray 7 in which the actual bobbin 5, which is conveyed by the conveyor belt 70, is inserted is moved to the stopper device 7.
1 and 72, the bobbin holder 74a, which rotates intermittently around the shaft 73 above the bobbin, slides down in the fixed block 76 by the rotation of the lever 75, and the chuck 77 at the lower end of the holder locks the bobbin. The core tube is forcibly clamped and raised to its original upper position. At the next one-pitch rotation position of the holder, the suction pipe 78 rises to unwind the tail thread, covers the bobbin, and the suction air unwinds the tail thread 79. Furthermore, the thread end of the bobbin is pulled out by the beater 80 and the suction mouth 80 at the one-pitch rotation position of the holder.

At a position further moved by one pitch, the thread connected between the suction mouth 81 and the bobbin is cut at the raised position by the cutter 82, and at the same time, the thread end suction pipe 83 is raised to the lower part of the bobbin, and the bobbin core A downward suction force is applied to the inside of the tube, and the cut yarn end is inserted into the core tube from the upper end of the bobbin.

The bobbin into which the yarn end has been inserted is lowered and inserted onto a tray waiting below, and is conveyed again by the conveyor 28 toward each unit of the winder.

Next, bobbin management using the above system configuration will be described in detail.

In FIGS. 6 and 7, winding is being carried out with the real bobbins in the real bobbin passages 35 of all the winding units A1 to An, and now, as shown in FIG. It is assumed that the trays 7e and 7f each having an empty bobbin are discharged onto the empty bobbin conveyor 29. When the trays 7e and 7f are conveyed in the direction of arrow 84 and pass in front of the photoelectric switch PS2, the photoelectric switch PS2 sends a two-pulse subtraction signal to the counter CO. On the other hand, a set value N is input in advance to the counter CO, and the display value is subtracted by a pulse input from the photoelectric switch PS2.

That is, the display is subtracted by 1 for each pulse of the subtraction signal.

In the case of the above example, the display is subtracted by 2 and the value N-2 is displayed.

The above counter CO is an addition/subtraction counter in which the output is turned on when the display is below the set value N, and the output is turned off when the display is above N.

Therefore, in the above example, two empty bobbins are discharged from winder A, and the counter display is N-2.
Therefore, the output from the counter is turned on, and as shown in Figure 7, relay RA is energized and contact RA is closed.Also, when the actual bobbin is waiting at the fixed position in front of the pick-up device, the micro switch in Figure 6 is activated. Since MS is closed, the relay MC for the magnetic switch for driving the picking device is energized, and the driving shaft 73 of the picking device is forcibly rotated one pitch.

At this time, the moment the real bobbin tray at the front end on the conveyor 70 in FIG. 6 is supplied to the pick-up device, the micro switch MS is opened, but as shown in FIG. By closing almost simultaneously with the forced rotation of , the drive shaft 73 of the pick-out device continues to rotate by one pitch w even if the micro switch MS is opened.

That is, the cam 84 rotates with the forced rotation of the drive shaft 73, and one rotation of the cam 84, that is, one rotation of the feed device.
The self-retention is maintained by keeping the switch PR closed during the cycle.

During one pitch rotation of the drive shaft 73, the bobbin of each holder moves one pitch, and during this time the suction pipe 78, beater 80, suction mouth 81, cutter 82, and suction pipe 8 at each position are moved one pitch.
After the device No. 3 operates once, it returns to its original position and stops, and the actual bobbin with the thread end inserted into the bobbin core tube is placed on the conveyor 28 and conveyed by being inserted into the tray. Ru.

That is, by rotating the shaft 73 one pitch W, one bobbin with the thread end inserted is placed on the tray. When the actual bobbin 5 is conveyed on the supply conveyor 28 shown in FIG. 6 and passes in front of the photoelectric switch PS1, an addition signal 1 pulse is output from the photoelectric switch PS1 and enters the counter CO, and the counter changes the display to N-1. shall be.

However, since it is still below the set value N, the output of the counter continues to be on, and the magnet switch MC is activated via relays RA and MC in the same manner as described above, and the drive shaft 73 shown in Figure 8 rotates one pitch further. Then, one real bobbin is placed on the supply conveyor 28 and supplied to the winder.

When the second bobbin passes through photoelectric switch PS1, one additional pulse of the addition signal is input to the counter CO, the counter displays the set value N, the output of the counter is turned off, and relay RA is de-energized. The supply of real bobbins is stopped.

In this way, the two real bobbins are connected to the winder A.
When the real bobbins are supplied to the winder A, the real bobbins are conveyed along the supply conveyor 28, and at the winding unit A1 position, a predetermined number of real bobbins 5 are stored in the passage 35. As explained in FIG. 4, the tray 7C at the rear end in the passageway 35 prevents the tray from entering, and it heads to the next unit.

Similarly, units A2 and A3 pass through when they are full, and one empty bobbin is discharged from unit A4, so there is a space for one tray in the passage 35, and the conveyor 28 The tray with the upper real bobbin inserted is the unit A4.
automatically enters the passage 35. Similarly, one real bobbin is supplied to unit An.

In this way, the photoelectric switch PS2 shown in FIG.
checks the number of bobbins discharged from the winder A, and if the displayed value of the counter CO decreases below the set value, the feed device T is immediately activated to constantly supply the same number of real bobbins as the empty bobbins discharged from the winder. , the total amount of real bobbins for the entire winder can be maintained at the set number at all times.

Although the above embodiment describes an example in which the system of the present invention is applied to a bobbin on the yarn supply side, it can also be applied to the case of supplying an empty paper tube on the winding package side.

In either case, it is necessary to provide a bobbin transport path passing through each winding unit and a taking means for taking the bobbins on the transport path into the storage section of each unit.

As described above, in the present invention, in a winder in which a plurality of winding units are arranged in parallel, a real bobbin conveyance path and an empty bobbin conveyance path are provided along each unit, and the real bobbin conveyance path and the empty bobbin conveyance path are provided at a position away from the winder on each of the above-mentioned conveyance paths. A detection switch that separately checks the number of empty bobbins and the number of real bobbins passing through the winder, and a counter that calculates the total amount of real bobbins in the entire winder based on the signal from the detection switch are provided. When this happens, the feeder for supplying real bobbins is activated to supply the winder with a number of real bobbins equal to the number of empty bobbins discharged from the winder. Therefore, each unit must be equipped with a bobbin detection switch. Without,
The bobbin can be managed for the entire winder, there is no need to install a detection device, wiring, etc. to issue a request command for the actual bobbin for each unit separately, and it is also possible to install dozens of wiring bundles. Therefore, the structure of the winder itself can be simplified, and a constant number of real bobbins can always be stored in the winder.

That is, the total amount of bobbins in the winder can be controlled and managed without instructing the supply and discharge of actual bobbins for each unit. In addition, since the winding unit is always fully stocked with real bobbins, even if the bobbin being wound becomes empty, the waiting real bobbin is ready to be supplied immediately. is close to zero, so the operating rate of the unit is extremely high.

In addition, since the number of real bobbins is supplied equal to the number of empty bobbins that are discharged from the winder, it is possible to prevent the excessive supply of real bobbins to the winder. Collapse can be prevented, and there is no need to provide a return path for the actual bobbin.
