Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous winding device for winding a strip of paper, plastic film, etc. around a winding core to create a winding roll.

In winding devices for strips of paper, plastic, etc., by pressing an elastic touch roll against the outer periphery of the winding roll while winding it up, the edges can be aligned better and the winding stiffness of the winding roll can be improved. It is already known that it has the effect of becoming constant.

However, when stopping the winding device after each winding roll, it is possible to keep the touch roller pressed against the winding roll from the beginning to the end of winding. The three arms are rotated, the strip is cut with a cutter, and the strip is sequentially wound around the winding core at the end of the arm. There is a drawback that it cannot be used.

(!) The figure shows the state of this device in the operating order, and the figure (a) shows the state at the beginning of winding on the winding core 1a. In each figure, ia and 1b are winding cores, 2 is an Arno arm that can rotate around the arm shaft 15, with winding cores 1a and ib attached to the tips,
7 is a support stand to which the arm shaft is attached. 4 indicates a running web (band-shaped body), and 4' indicates a take-up roll. The running web 4 is guided by guide rollers 5 attached to a frame 8 and wound around the winding core 1a or 1b.

Reference numeral 6 denotes a touch roller attached to the tip of a lever that is pivotally attached to the frame 8, and 6 is a cutter that is pivotally attached to the frame 8.

(b) In the state shown in the figure, the touch roller 3 is in contact with the take-up roll 4'. (Figure 0 shows the state where the take-up roll 4' has become larger and is just before the end of winding. In this state, the touch roller has finished rolling. The figure shows the state immediately before the cutter operation begins.The touch roller 3 must be separated as soon as the rotation starts.In the figure, the cutter 6 enters the running web 4, and at the same time as cutting begins winding onto a new core 1b. This shows the state that has become. (E) The figure shows the cutter 6 returning to its normal position and a new winding core 1b.
The touch roller is finished, and the winding core 1a is in a immersed state, indicating that the winding is complete. As can be seen from the above explanation, between the states shown in Figures (C) to (E), the touch roller 6 moves from the take-up roll 4' to the P! [(E) In the figure, it means the old take-up roll.]

Therefore, during this time, the edges of the winding roll 4' are not aligned properly, and the winding stiffness cannot be adjusted.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to improve the yield of the strip by pressing a touch roll against the surface of the take-up roll from the beginning to the end of winding the strip onto the core. The object of the present invention is to provide a continuous winding device capable of obtaining stable winding quality.
