Abstract

PURPOSE:To prevent the formation of half-wound packages by enumerating the residual yarn feeding quantity of a yarn feeding package at the time of a take-up package reaching the fully wound state and deciding whether or not to proceed to the following winding according to the enumerated residual quantity. CONSTITUTION:When a yarn feeding package P is confirmed to be in a take-up position, the residual yarn quantity to be wound until a take-up package S on a drum 6 reaches the fully wound state is obtained by a control device 28. The yarn feeding residual quantity of the yarn feeding package at the time of the take-up package S on the drum 6 reaching the fully wound state is enumerated in advance from the obtained residual yarn quantity to be wound to the package S. When this yarn feeding residual quantity does not suffice the yarn feeding quantity equivalent to one package (fully wound quantity) of the take-up package S, the winding of the specified number of yarn feeding packages P is judged to be terminated, and the following winding is stopped leaving the residual yarn of the package P as it is.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention supplies a predetermined number of yarn feeding packages to a winder,
Regarding the winding method in which the yarn supply package is wound by a winding package on a drum, in particular, it is important to note that the winding package that winds the yarn from the last yarn supply package supplied to the winding position of the winder unit becomes a half-ball. This relates to a method of winding that can be prevented.

[Prior Art] Generally, a cone-toe-cone type winder is known, which rewinds the package discharged from the spinning winder as a package according to the next process such as dyeing.
In this winder, yarn feeding packages supplied to each unit according to type are wound up by a winding package that is rotated on a drum.

[Problems to be Solved by the Invention] Incidentally, in this type of winder, a predetermined number (10 tons) of yarn supply packages are supplied, and the supply of a predetermined number of yarn supply packages predetermined for each type is not possible. Once completed, the winding will be finished.

At this time, when the winding package on the drum that has wound the yarn from the last yarn supply package to the winding position of the winding unit reaches a preset full winding amount, the yarn remains in the yarn supply package. The remaining amount of yarn fed in this yarn feeding package may be equivalent to the full amount of winding of the winding package, or may be less than the amount of one batch. If there is a remaining yarn supply amount that is more than the full winding amount, winding is performed for one package and one more stitch, so in any case, the yarn supply package contains yarn that is less than the full winding amount of the winding package. A large amount will remain.

Therefore, when yarn is wound up using a winding package on a drum from such a yarn feeding package with a small amount of yarn remaining, there is a problem in that a so-called half-ball package is formed, which is less than the preset winding amount. .

The present invention has been devised to effectively solve the above problems.

The present invention is a winding method that prevents a winding package for winding yarn from a yarn feeding package supplied after fi from becoming a half-roll, and can always form a preset full winding amount. The purpose is to provide

[Means for Solving the Problems] The present invention provides a system in which the winding package is full when the last yarn feeding package is supplied to the winding position of each unit of the finder.
Determine the amount of yarn remaining to be wound until IBM is reached, calculate the yarn feeding TAJl of the yarn feeding package when the winding package reaches full winding from that amount of yarn remaining to be wound, and calculate the yarn feeding TAJl of the yarn feeding package when the winding package reaches full winding. This is to determine whether or not to perform the next winding.

[Operation] First, a predetermined amount of yarn supply packages are supplied to the winder, and
When the supply of all yarn supply packages is completed, it is determined whether the yarn supply packages after I& have been supplied to the winding position of the winding unit.

Next, when it is confirmed that the yarn supply package has been supplied to the winding position, the amount of yarn remaining to be wound until the winding package on the drum at that time reaches the full winding amount is determined. From this amount of remaining yarn to be wound, the amount of yarn remaining in the yarn feeding package when the winding package on the drum that winds the yarn from the last yarn feeding package reaches its full winding amount is calculated in advance. When the remaining amount of yarn feeding is less than the yarn feeding side of one bag of winding packages (full winding amount), it is determined that winding of a predetermined number of yarn feeding packages has been completed, and the remaining yarn feeding side is The next winding is stopped while leaving the thread.

[Actual '1fA Feed] Hereinafter, one embodiment-1 of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show a cone-to-cone type winder for winding yarn from a package to further form a package.

As shown in the figure, a winder 1 consisting of a large number of winding units is formed, and a real tray transport path 2 for transporting a real tray Q in which a yarn supply package P is inserted is connected to the winder 1. Empty tray R discharged from
An empty tray transport path 3 for transporting the empty trays is connected.

Further, the winder 1 is composed of a plurality of winding units 4 as shown in FIG. 3, and these units 4 are operated according to the type of package. Five types of yarn feeding packages P are supplied. For example, in the case of type A, eight units 4 are supplied.
is now being driven.

Each winding unit 4 is connected to a take-in passage B5 that takes in three yarn feeding packages P from the actual tray conveyance path 2. Two yarn feeding packages P are waited in this taking-in passage 5, and the winding Above the yarn feeding package P at the position, a winding package S is rotatably driven on a drum 6 to wind up the yarn.

Further, the actual tray transport path 2 and the empty tray photographing transport path 3 are connected to an annular transport path 8, and this transport path 8 includes a glow device MxO for extracting the bobbin from the empty tray R and a yarn end from the yarn supply package P. A pick-up device r11.9 for picking the yarn is provided, and a package supply device 11 for inserting the yarn supply package P into the empty tray R discharged from the pick-up device 9 is also provided. The package supply device 11 supplies a predetermined number of yarn supply packages P for each product type to the winder L.
It is designed to supply Therefore, the predetermined number (1
When the number of packages (for 0 tons) is supplied to the winder 1, the empty tray R discharged from the winder 1 is supplied to the intake passage 5 of each unit 4 without the yarn feeding package P being attached to it. be done.

In particular, a package detection device 21 is provided in the intake passage 5 of each unit 4 to detect when the last yarn supply package P is supplied to the winding position of the unit 4.

This detection device 21, as shown in FIGS. 3 and 4,
It has a U-shaped lever member 24 provided at four parts of the intake path 5 consisting of a roller conveyor 22 and a guide plate 23, and the tip of this lever member 24 is attached to two waiting yarn supply packages P. The base end portion is supported by the support frame 25 so as to be freely raised and folded. A spring 26 is provided at the base end of the lever member 25 to bias the tip of the lever member 25 toward the yarn supplying package P.
A limit switch 27 is provided. This limit switch 27 is activated when the lever member 24 is separated from it.
Operates as FF and turns ON when approached.

Therefore, there are two yarn feeding packages P in the intake passage 5.
When the tray R is on standby, the lever member 24 is pushed up by these yarn supply packages P and stands up, and when two empty trays R are on standby, the lever member 24 falls and the last yarn supply package P is at the winding position. is detected.

Further, the package supply device 11 and the package detection device 21 are connected to a control device 28, as shown in FIG. At the same time, the package detection device 21 inputs that the last yarn supply package P has been supplied to the winding position.

In addition, the control device 28 is inputted with the yarn feeding amount of the yarn feeding package P, the full winding amount of the winding package S, and the count, which are set in advance for each type of package. Based on these data, the control device 28 determines the amount of yarn remaining to be wound until the winding package S on the drum 6 reaches the full winding amount when the last yarn feeding package P is supplied to the winding position of the unit 4. demand. Further, from this winding remaining yarn amount, the yarn feeding remaining yarn amount of the yarn feeding package P when the winding package S reaches full winding is calculated. The control device 28 determines whether or not to enter the next winding depending on the amount of yarn remaining in the yarn supply package P. That is, the remaining yarn feeding amount of the yarn feeding package P and the full winding amount of the winding package S are compared, and if the yarn feeding remaining amount of the yarn feeding package P is less than the full winding amount of the winding package S, It is determined that a predetermined number of windings have been completed, and the next winding is stopped.

Next, the winding method will be explained with reference to FIGS. 1 and 6.

First, as shown in FIG. 6, it is confirmed whether or not a predetermined number (10 tons) of yarn feeding packages P have been supplied. A
To explain the types, in the case of type A in FIG. Three yarn feeding packages P are supplied to the yarn supplying section 4.

As shown in FIG. 6, when the supply of a predetermined number of packages P is completed, the package supply device 9 notifies the control device 28 that all the supplies have been completed. Further, when the supply of all the yarn feeding packages P is completed, the empty tray R discharged from each unit 4 is supplied to each unit 4 again. When two empty trays R are supplied to the unit 4, the package detection device 21 detects that the last yarn supply package P has been supplied to the winding position of the unit 4, and transmits this to the control device 28. .

When it is confirmed that the last yarn supply package P has been supplied, the control device 28 determines the amount of yarn remaining to be wound until the current winding package S on the drum 6 reaches full winding. From this, the remaining amount of yarn feeding in the yarn feeding package P when the current winding package S reaches its full winding amount is calculated.

For example, the yarn supply amount held by the yarn supply package P is 2.2
kg, and the full winding amount of the winding package S is 1. shg is preset, and the current winding amount of the winding package S is 1.2 kg.
When 1.5-1.2 = (], 3tta is the amount of yarn remaining to be wound in the current winding package S. Therefore, when the winding package S becomes groove winding, 2.2 k (1-0,3k(] = 1.9 kg is the remaining amount of yarn feeding in the yarn feeding package.

In this way, when the current winding package S becomes groove-wound, the calculation of the remaining yarn amount of yarn feeding package P is completed, and
When the current winding package S actually reaches its full winding amount, it will be determined whether or not to perform the next winding.

That is, the remaining amount of yarn fed in the yarn feeding package P and the full winding amount of the winding package S are compared and calculated. In other words,
The weight of both will be compared.

Therefore, if the remaining yarn feeding amount of the yarn feeding package P is less than the full winding amount, it means that the yarn feeding amount for one batch is not left in the yarn feeding package P. It is determined that several (10 tons) of winding have been completed, and the winding is stopped with the yarn remaining in the yarn supply package P.

Therefore, when the yarn feeding amount of the yarn feeding package P is larger than the full winding amount, the yarn feeding amount for one batch is left, and in this case, further winding is required. In the above example, since the remaining yarn amount is 1.9k (J), further winding is possible.

When the next winding is performed, the yarn supply package P does not have the full amount of yarn left, so the next winding will not be performed.

In this way, the present invention calculates in advance the remaining yarn feeding amount of the yarn feeding package P when the winding package S that winds the yarn from the last yarn feeding package P reaches groove winding, and calculates the remaining yarn feeding amount of the yarn feeding package P. Since it is determined whether to enter the next winding depending on the amount of winding, it is possible to prevent the formation of a winding package of half balls.

[Effects of the Invention] In summary, according to the present invention, when the winding package that winds the yarn from the yarn feeding package last supplied to the winding unit reaches full winding, the remaining yarn feeding amount of the yarn feeding package can be calculated. Since it is determined whether or not to start the next winding according to the amount of remaining yarn, it is possible to prevent half-ball winding luggage from being formed.
