Abstract

PURPOSE:To shorten the waiting time by storing the constant length data and yarn kind data of each package of all spindles in taking-up operation into a memory device by a controller at the time when a lot changing switch is turned-ON and executing doffing by attaching a spindle recognition code onto each package. CONSTITUTION:When a lot changing switch 3 for the old and new lots having different kind of yarn is turned ON, the constant length data of each package of all spindle and the yarn kind data are automatically stored into a memory device, e.g., into an IC card inserted into an insertion port 4, independently in the taking-up operation or not at present. The package is applied with a spindle recognition No. belonging to a certain winder unit 1, e.g., spindle No., and once doffing-treated by an autodoffer 12. At the same time, the replacement from the old lot to a new lot of a cop on all spindles of the winder unit 1 is carried out in a cop discharging device 7 and a cop feeding device 8. Therefore, the need of waiting all the spindles in full state is obviated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fixed length winding method for an automatic winder.

[Prior Art] Generally, an automatic winder is made up of multiple winder units arranged side by side, and the packages grooved in each winder unit are doffed by a doffer each time and for each winder unit.

Conventionally, while the above automatic winder is in operation, if you want to change the lot with a different yarn type and wind a different type of yarn, wait until the package of the winder unit of all spindles is grooved, and I was exchanging the tube thread for the new lot and the new lot, and starting the automatic winder.

[Problem to be Solved by the Invention] However, it is normal that the time at which the packages of the old lot are grooved in each winder unit differs considerably in time for each winder unit, and all winder units The existence of a waiting time until the package is grooved significantly reduces the operating efficiency of the automatic winder as a whole.

The present invention has been made in view of the above problems, and provides a fixed length winding method for an automatic wine gourd, which eliminates the waiting time during lot change and allows packages to be wound to a fixed length as specified. There is a particular thing.

[Means for Solving the Problems] The fixed-length winding method of the automatic winder of the present invention splits the winding of a new loft yarn of a different yarn type during the winding of an old lot yarn by a winder unit with multiple spindles. When the lot change switch is turned on, the control device stores the fixed length data and yarn type data of the packages of all the weights being wound in the storage device, and the auto docker recognizes these packages as weights. While dotting with a code, the threads of all spindles are exchanged from the old lot to the new lot, and after the new lot's thread is wound in a prescribed manner, the package of the old rod is handled based on the weight recognition code. The control device reads the data stored in the storage device, and resumes winding of the old lot from where it left off.

[Function] When the lot change switch for old and new lots with different yarn types is turned on, the fixed length data and yarn type data of the package of all valves are automatically changed regardless of whether winding is currently in progress or not. The information is stored in a storage device, such as an IC card or internal memory.

Further, the package is given a weight recognition code indicating which winder unit it belongs to, for example, a weight number, and then doffed. In parallel with this, the replacement of the old lot of yarn with the new lot in all spindles of the winder unit is started. Therefore, when performing a lot change, there is no need to wait until the time to turn on the lot change switch until all the packages of all the spindles of the winder unit have been grooved, and the lot change starts immediately after the lot change switch is turned on.

When the dotting of the package of the old lot and the exchange of the yarn between the old and new lots are completed, the yarn of the new lot is wound. During this time, the fixed length data of the old loft, etc., in the case of an IC card, for example, are stored and retained without being erased.

When winding of a new lot of yarn is finished and you want to continue winding with the yarn of the old loft from where it left off, the package of the old loft is attached to the corresponding original weight based on the weight recognition code assigned to it. At the same time, the fixed length data and yarn type data stored in the storage device are read from the storage device, and according to this data, winding of the package of the old lot is continued from where it left off last time.

Therefore, even if it is desired to change the lot urgently during winding, the loft can be changed quickly without producing a large number of half-ball packages.

[Example] The present invention will be described below based on illustrated embodiments.

In FIG. 1, reference numeral 1 denotes a winder unit constituting an automatic winder, and in this example, 60 winder units are arranged side by side. One end side of these wine goo unit groups (left side 1 in Figure 1)
The control box 2 installed in the control box 2 is provided with a lot change switch 3 and an insertion slot 4 for a memory card called an IC card. A change lamp 5 and an old lot discharge lamp 6 are provided to indicate that the old lot is being discharged. 3a shows an old lot restoration switch.

At the other end of the wine goo unit group (right side in Figure 1),
A yarn discharge device 7 for discharging the old lot of yarn collected during loft exchange, and a yarn supply device 8 for supplying the new lot of yarn having a different yarn type from the old lot are provided.

In a normal winding operation, the same type of pipe yarn 9 sent from the pipe supply device 8 is placed on a bobbin tray and is constantly circulating and waiting along the loose supply conveyance path 10. When the rewinding of the pipe yarns in one wine goo unit 1 is completed, these pipe threads 9 are automatically set in the wine goo unit 1 as necessary, and are separated from the half-ball package 11 which is currently wound halfway. The threads are automatically spliced. Through the same process, wine goo unit 1
New pipe threads 9 are set one after another, and winding is continued until the package 11 is grooved.

Incidentally, the empty bobbin is sent through another discharge conveyance path and discharged from the yarn discharge device 7 to the wagon 70.

When a predetermined length of yarn is wound and the package 11 is grooved, the auto doffer 12 common to the wine goo unit group is activated, moves to the position of the wine goo unit, and automatically doffs the groove package 11. do. That is, the doffing mechanism 13 of the autodoffer 12 presses the groove package 11 toward the rear of the automatic winder to remove it from the cradle, and drops the groove package 11 onto the barragage conveyor behind the automatic winder. They are collected at a predetermined location by a ceiling hanger transport system (not shown).

In addition to the doffing mechanism 13, the autodoffer 12 includes a printer 14 for marking the weight number of the wine goo unit on the package;
It has a built-in control device 15 for controlling 4 and doffing tl[13. A control device 16 is also provided in the control box 2 to issue operation commands to the autodoffer.
Communication with control box 2 and dotufa 12
This is done via optical communication devices 17 and 18 provided on opposite sides of the .

In FIG. 2, the control device 16 is basically a CPU, R
It has a microcomputer 20 including OM and RAM, and its I10 boat 21 includes a lot change switch 3, a lot change lamp 5, an old lot discharge lamp 6,
A yarn discharge device 7, a yarn supply device 8, and an old lot recovery switch 3a are connected. 22 is a scanner for sequentially controlling or monitoring the wine goo unit group one by one, and 23 is a clock signal that defines the scanning speed of the scanner 22. Information obtained from each wine goo unit 1 via the scanner 22, in particular the package fixed length counter data, is temporarily held in the I10 boat 21 until it is read by the microcomputer 20. The optical communication device 17 consists of a modem 17a and a photoelectric converter 17b, and the modem 17a has 110 ports 2
Connected to 1. The optical communication device 18 on the autodoffer side similarly consists of a photoelectric conversion device 18a and a modem 18b, and the modem 18b is connected to a control device 'fl15 built into the autodoffer 12. Reference numeral 24 indicates a feeding device of the auto-doffer, and 25 indicates a position sensor for the position of the weight to be stopped.

Next, with reference to FIGS. 3 to 5, an explanation will be given of the operation of the automatic winder having the above-mentioned configuration when the thread currently being wound is urgently changed lots to a different type of thread.

When the lot change switch 3 is turned on, the control device 16
The microcomputer 20 gives commands to the wine goo unit 1, the yarn discharge device 7, the yarn supply device 8, and the auto docker 12, or receives signals, according to the program shown in FIG. 3 stored in the ROM. and perform the loft change control described below.

First, in FIG. 3, when the lot change switch 3 is pressed by the worker and turned ON (step ■), cp
u turns on the lot change lamp 5 to indicate that the lot is being changed, and turns off the winding motors (not shown) for all spindles of the wine goo unit (steps ■, ■
) 0 Next, wait for the winding drum of each wine goo unit 1 to come to a standstill (step ■). This is because the winding drum continues to rotate due to inertia for a certain amount of time even after the motor is turned off, so it is impossible to determine the point at which it has completely stopped. This is to obtain long counter data as constant length counter data of the correct package. When the winding drums of all the spindles have stopped, check that the memory card, that is, the IC card, is inserted into the insertion slot 4, and then write the fixed length data of all 60 spindles, that is, the fixed length counter data of the package, to the memory card. and at the same time also write the thread type data and machine number of the lot (Steps /P■,■
).

Once the fixed length data has been stored, the pipe discharge device 7 is operated to discharge the pipe of the old lot, and
Turn on the old lot discharge lamp 6 to inform the operator that the pipe yarn of the current lot is being discharged (steps ■, ■);
At the same time, the pipe supply device 8 is operated to supply a new lot of pipe yarn with a different yarn type to the winder unit 1 (
Step ■).

On the other hand, the feeding device 24 of the auto-dosher 12 is operated (step o), and the winder units 1
Here, each time the position sensor 25 reaches the corresponding weight position, the printer 14 is activated to attach the weight number to which the half-ball package belongs, and then the half-ball package is doffed (step 0-◎), the weight numbers are assigned, for example, by pasting labels with ■, ■, ■...Q tiles.

When the above-mentioned spindle number assignment and doffing of the packages are completed for all 60 spindles, the accompanying movement of the auto-dropper 12 is stopped (step (9, (ED)).

Next, in order to confirm that all the pipe yarns of the old lot set in the winder unit 1 have been discharged and that the pipe yarns of the new lot have been set in all the winder units 1, the pipe yarn supply conveyance path 10 is and checks whether the empty tray is the only yarn existing in the discharge conveyance path (step O). When the exchange of the old lot and new lot tube yarn is completed, the old lot discharge lamp 6 is turned off. The operator is informed of this (Step O).

After this, the winding operation is the same as that of a normal automatic winder, and the start switch la (Fig. 1) is turned on by the operator.
Then, the new lot of pipe yarn is wound by each winder unit 1. In this case, the constant length counter data of each package of the new lot starts from zero. When all 60 packages are grooved or a predetermined number of grooved packages are formed, the winding of the new lot of thread onto the packages ends. It should be noted that the packages with weight numbers ① to e of this frontage lot are stocked at a predetermined location. Also, lot change lamp 5
continues to light, indicating that an interrupt is in progress.

In FIG. 4, when the winding of the new lot is completed, the yarn of the new loft is automatically discharged from the automatic winder by the yarn discharge device 7, and instead, the yarn of the new loft is discharged from the automatic winder.
automatically supplies the old lot pipe yarn of the same yarn type as before the lot change (steps O~0>.The operator also inserts the half-ball package of the old lot into the winder unit of the corresponding weight according to the weight number attached to it. When the setting of the old lot's tube yarn and half-ball package is completed (step 9.6),
The lot change lamp 5 is blinked to inform the operator that winding should be continued with the thread of the old lot (step O).

In FIG. 5, the CPU is waiting for the old lot restoration switch 3a to be pressed by the operator.

When the old lot restoration switch 3a is turned on (step 0
), confirm that the obituary card is inserted into the card insertion slot 4 (step O), and save the fixed length counter data, yarn type data, etc. of the old lot written in the memory card into the RAM. Once the data has been read (step O), the winding of the old lot can be continued without any electrical errors, so the lot change lamp 5 is turned off (step O).

After this, the process is the same as in normal operation, and each winder unit enters the winding operation after waiting for the unit start switch la (Fig. 1) to be turned on (step 0. [phase]). Winding is continued until the half package becomes a groove, at which point the winder unit is temporarily stopped and doffed.

In the above embodiment, the fixed length counter data of the old lot is stored in the storage card, but the storage card is not limited to this, and an appropriate external storage device may be used.
6 may be provided with a non-volatile memory or the like and stored therein.Also, although the printer 14 of the auto-dosfer 12 attaches a weight number to the package, it is possible to use a weight identification code that can identify the weight to which it belongs. For example, it may be an alphabet.

[Effects of the Invention] As described above, in the constant length winding method of the present invention, when the lot change switch is turned on, the package being wound is immediately doffed. can be done at any time,
There is no need to wait until all the packages are grooved, and after winding a new lot, the winding of the original package can be continued from the previous time based on the fixed length data and yarn type data of the old lot. Since the roll is restarted from the previous lot, the half-ball packages of the old lot can be wound to a desired length, and the inconvenience of having a large amount of half-ball packages in the past can be prevented.
