Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a core winding preparation method and an adhesive material applying device in a winder for winding a web made of yam or plastic onto a core.

Prior art> As shown in Fig. 8, a winder (web winding device)
Web W unwound from a manufactured roll (not shown)
is divided into predetermined width dimensions by the surinotar 4, and then guided between a pair of drum rolls 1 and 2.
The tip end is fixed to the core 3 carried on the core 2, and the drum roll is rotated to wind it up to a predetermined outer diameter. Then, the rolled roll is pushed out to the unloading side, and at the same time, the roll and the following web W are separated. Then, for the next winding, a core with a drying material such as double-sided tape is attached. 3 is carried between drum rolls 1 and 2.

In such a winder, during the winding operation of the web W, the current slint width A, B, C or the next loft slint width A'. B'. Core 3A with the same length as C',
It is necessary to arrange the cores 3B and 3C in the core loading device 5 in order to prepare for the next winding. Two methods have been adopted: one is to insert the core 3 into the core carrying device 5 using P, and the other is to insert the core 3 into the core carrying device 5 while the operator checks the length of the core 3 from the work side of the winder.

<Problem that this invention seeks to solve>? Winding the core as described 1! When preparing for the next winding, the core diameter, core length, arrangement 1 injection order, etc. are checked and inserted from the necessary information of the core for the next winding.
There are many types of lengths, and the arrangement differs depending on the length.
There is a high possibility that the core arrangement will be incorrect due to a work error. For example, if the order in which the cores 3 are arranged is incorrect, the cores will sink into other take-up rolls, as shown in FIG.
A, RB, and RC can no longer be divided.

Furthermore, even if the product can be divided, the core may protrude, causing it to be out of spec, making it impossible to ship.

Moreover, if the following operation is performed while intending to insert the core 3 into the core loading device 5 from the core storage S or the work side, the problem of forgetting to insert the core may occur.

This invention was made to solve the above-mentioned problems, and its purpose is to make it possible to arrange the cores without installing any special equipment, and to eliminate the need to carry the cores into the winder. It is an object of the present invention to provide a core winding preparation method for a winder and an adhesive material pasting device that can easily and quickly perform the work of pasting the adhesive material.

<Means for Solving the Problems> The core winding preparation method according to the present invention includes
The adhesive pasting unit 8 is run along the core carry-in device 5 that carries in the cores, and the adhesive stick 6 is pasted on a plurality of cores 3 that are consecutively arranged in the longitudinal direction on the core carry-in device 5 (see Fig. 2). , see Figure 5), before pasting the adhesive material 6, the first
As shown in the figure, the length measurement sensor 9 is moved along the core 3 together with the adhesive pasting unit 8, and the distance L to the core 3 is measured while detecting the running position L, and this core detection result and core information are combined. Then, as shown in FIG.
It is designed to be pasted.

The equipment for carrying out such a method runs along a core carrying device 5 that carries the cores 3 into the winder, and a plurality of cores 3 arranged continuously in the longitudinal direction on this core loading device 5. An adhesive pasting unit 8 for pasting an adhesive 6 such as double-sided tape, and a core 3 provided in this adhesive pasting unit 8.

(See Figure 3).

<Function> From the measured traveling device L and distance Ml, the core diameter, core length,
The arrangement order of the cores and the presence or absence of cores are determined. If a core is present, the measurement data is compared with core information such as automatic positioning data of the slitter 4, and the arrangement status of the cores 3 (core diameter, each core length) is determined. The overall length of the core, the arrangement order of the cores, and the presence or absence of the cores) are confirmed before the adhesive material 6 is attached. This eliminates the need to carry the core 3 into the winder.

If the measured data and core information match, the adhesive pasting unit 8 is made to travel in the opposite direction, and while the traveling position is detected by the position detection sensor 10, the operation of the adhesive pasting unit 8 is controlled using the measured data. Adhesive material 6 is attached to core 3. Since there is no need to input data from elsewhere, pasting work can be done quickly.

<Example> As shown in Fig. 5, this is an example applied to a two-drum winder, in which a pair of drum rolls 1.2 are arranged in parallel, and the unloading side of the drum rolls 1 and 2 is arranged in parallel. Then, a core carrying device 5 carrying the core 3 to the upper part between the drum rolls 1.
