2. Description of the Related Art A winding machine that slits a sheet fed from a preceding process into a plurality of strips and winds the sheet into a core tube having the same number as the number of cut strips arranged on a core shaft is known as a slit winding device. It is widely used for winding films and sheets.

However, in such cutting and winding, the slit width is not always constant, and the core tube at the time of winding, which is usually a paper tube, often has a different size.

Conventionally, when there is a change in the size of the core tube, that is, the diameter and the width, a core tube cut to a required size in advance is purchased and set by hand each time. I was

[0005]

However, it is very troublesome to set a new one every time the size of the core tube changes, and it is necessary to stop the winding machine each time. As a result, the production efficiency could not be reduced.

The present invention addresses the above-mentioned facts, and automatically changes the size of the core tube by making it possible to cut and supply a wide single core tube according to the slit width. Another object of the present invention is to improve the winding efficiency of the slit winding device in a simple and easy manner.

Apparatus is disposed in the vicinity of one side of the turret apparatus, takes out one wide core tube, inserts the core tube into one of the core tube mandrels, and grips the core tube. The wide single core tube is held by the core tube mandrel and provided in the middle of rotation to the lower position in the turret rotation direction, and has a cutting blade at the tip of a rotatable cutting arm. A core tube cutting device for cutting into a plurality of narrow core tubes according to the number It is provided on the side of the core tube mandrel rotation position below the turret device, and has a core tube receiving stand that integrally holds the cut plurality of narrow core tubes so that it can be moved up and down. Core tube transfer device The core tube transfer device is sandwiched between the core tube cutting device, and the integral narrow core tube held by the core tube mandrel is raised by the transfer device. And a core tube extracting device for extracting the core tube from the core tube receiving stand, and a series of operations of the respective devices is automatically controlled by sequence control.

In particular, the present invention aims at automating the cutting and supply of core tubes having different diameters, and the invention according to claim 2 clarifies this, and the core tube mandrel at a symmetric position is clarified. The cutting depth of the core tube cutting device and the core tube receiving pedestal of the core tube transferring device are adjusted to the diameter of the core tube, and the cutting depth and pedestal height are set to one for large diameter and the other for small diameter. Each stroke is connected to a selectable air cylinder so that it can be varied.

In addition, the automatic winding system of the present invention using the core tube cutting and feeding device is as follows: (a) A wide sheet is cut into a plurality of strips having a required narrow width and a plurality of narrow sheets arranged on the same core shaft. (B) A full roll transfer device that receives a full roll wound on a rotatable and tiltable tray and transfers it forward. (C) A full roll on the tray, and a roll.

The first one is sent out, and cutting and supply of the core tube start.

That is, the roll which has been wound up by the winding machine on the narrow core tube on the same winding core shaft and is full, immediately after the winding machine, is located at the full roll receiving position at the full roll receiving position. Then, the end of the winding is cut and wrapped, and then moved forward, the core shaft is pulled out and placed on the core shaft rest.

When the core is removed from the full roll,
With the full roll from which the core shaft has been removed, the full roll transfer device is moved to the new core receiving position and the tray is rotated to discharge the full roll toward the next step. Then, the full roll transfer device receives the same number of new core tubes as the number of slits cut into the core width corresponding to the slit width by the core tube cutting and supplying device at the position on the tray, and retreats to the tray. Raise to the core shaft insertion height, insert the core shaft pulled out of the full roll earlier and placed on the core shaft rest,
A new winding core for the next winding is formed.

On the other hand, when the full roll is removed in the winding machine, another winding core placed at the winding core supply standby position is fed into the vacant winding portion and pressed and pressed, and the above-described cutting is performed. The cutting end of the sheet separated from the full roll by the apparatus is wound around the new winding core, and the next winding is started.
At this time, the new winding core formed at the above position is picked up by the conveyor device, and is conveyed and mounted to the winding core supply standby position, thereby completing a series of operations. The above-described series of operations and control is performed by a series of sequence controls.

Then, the feed screw 69 is rotated to move the core tube holder 71, and the final core tube 15-6 shown in FIG. 10A is transferred to the core tube receiving base 77, and the core tube 15-6 after the trailing edge has withdrawn the core tube to the state placed on the Makishinkan mandrel 24 Wazuka, the winding core tube pressing arm 70 parked feeding stops the motor M ₄ in Makishinkan mandrel 24 by rotating the air cylinder in a direction away against reverses the motor M _4, slightly away position tip in the direction of the axis of Makishinkan presser 71 from the rear end of the final winding core tube 15-6 to slider 67 backhaul to stop the motor M ₄ to the winding core tube arm 70 Following
When the towards the winding core tube mandrel 24 is rotated by the air cylinder 72, to advance the slide frame 67 by driving the motor M ₄ again, the tip of Makishinkan presser 71 as shown in FIG. 10 (b) Comes into contact with the rear end surface of the final core tube 15-6, pushes out the core tube 15-6 with the movement of the core tube retainer 71, and moves the slide body 67 to the end point of the feed screw 69, as shown in FIG. As shown in (c), all of the useful core tubes cut are slidably moved on the gutter-shaped core tube receiving base 77 and pushed out to the full roll transport device.

Since the full roll transfer device IV has been moved to the new core receiving position as described in the above description adjacent to the trough type core tube receiving base 77, the tray 3 of the device has been moved. The core tubes discharged through the gutter-type core tube receiving base 77 are transferred in a horizontal line.

Thereafter, these core tubes are inserted into the core shaft to form a new core, conveyed by the conveyor device 13 and supplied to the winding machine II, in the order described in the outline. is there.

A sequence control technique is applied to the control of the operation of the series of automatic winding core tube cutting / supplying devices. However, the technique is well known, and a detailed description thereof will be omitted.

[0048]

As described above, the present invention is configured such that a wide, single core tube is cut to fit a required slit width and supplied to a winding machine. When the diameter or width of the pipe changes, it is necessary to purchase, cut, and supply by hand a predetermined diameter and a predetermined width, eliminating the need for such a thing. When only a real core tube is prepared, it is possible to automatically cut and supply according to the large or small diameter or according to the number of discretion, and when using this to perform a series of winding It has the remarkable effect of improving the work efficiency of slit cutting and eliminating automation and promoting automation.

In particular, the core tube cutting / supplying device of the present invention can be used in conjunction with a conventional winding machine.
It is very advantageous.
