Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method and device for automatically rolling up a coat in a coat calendar, and more specifically, the present invention relates to a method and device for automatically rolling up a coat in a coat calendar, and more specifically, the present invention relates to a method for automatically winding up a coat in a coat calendar, and more specifically, to The present invention relates to a method for automatically winding up a coating material, which can be reliably and automatically wound onto a winding roll without requiring a winding roll, and an apparatus therefor.

[Prior art]

Conventionally, the tip of the coating material supplied from the molding process was wound alternately around multiple winding rolls.
Further, all operations for cutting the end portions of the coating material were performed manually based on the operator's experience.

For this reason, depending on the skill level of the workers, the cut surface of the end of the coating material may be uneven, or wrinkles may occur due to poor winding of the take-up roll into the cells, resulting in the tip of the coating material becoming uneven. There were problems such as defective products and inability to perform efficient rolling operations.

Furthermore, since all of the winding and cutting operations described above were performed manually by workers, safety of the operations became a problem. In addition, in the past, for example, Japanese Patent Laid-Open No. 59-230936 and Japanese Patent Laid-Open No. 59-230936
As disclosed in Publication No. 230937, an automatic rewinding device and rewinding method have been proposed in which the leading edge of a sheet material is automatically wound around multiple rolls alternately and cut by a cutting device. . The conventional device described above has a pair of guide conveyors swingably arranged vertically below an automatic cutter device for cutting sheet products that hang down after passing through pinch rolls, and the sheet products are arranged on the left and right. The liner is wound alternately onto the liner wound around two winder shafts.

However, in the case of this device, the lower end of the sheet cut by the automatic cutter device is held by the clamp device, but since the end portion falls due to its own weight, the end portion may be wrinkled. Also, when the end of the sheet is removed from the clamping device due to the rotation of the winder shaft, wrinkles similar to the above may occur before the end reaches the entrance of the guide conveyor located below. Furthermore, since the swinging angle of the guide conveyor is always constant, it is difficult to guide the sheet by positioning the end of the sheet close to the winder shaft. When the winder shaft is moved, there is a problem that if the diameter of the winder shaft on which the sheet is wound increases, the winder shaft will come into contact with the winder shaft.

[Purpose of the invention]

This invention was devised by paying attention to such conventional problems, and its purpose is to automatically roll up the tip of the coating material.
The coating guide device that swings in multiple stages guides the tip of the coating material to the vicinity of the cells.
Winding can be done safely and reliably without creating wrinkles at the tip of the coating material, and after winding is completed, the cell is cut near the winding part, which makes it possible to The coating material automatic coating method in the coating calendar does not cause wrinkles or the like to occur at the tip of the coating material, and also reduces the winding time for a certain length of the coating material, significantly improving the winding efficiency. The present invention provides a winding method and device.

[Structure of the Invention] In order to achieve the above-mentioned object, the present invention has been made in such a manner that when the coat material supplied from the molding process is unwound to a predetermined length, the tip of the coat material is moved through the first and second swing arms. The tip of the coating material is positioned between the liner and the cell, which has been wound loosely around the take-up roll, and the liner and the cell are moved. The coating material is continuously wound to a predetermined length using frictional force between the coating material and the end portion of the liner, which is stretched under a constant tension. The gist of this is that the cutting is performed using a device.

In addition, the present invention includes a first swing arm that is swingably suspended from a support frame constructed over a plurality of take-up rolls arranged in parallel via a swing device, and At the tip of the first swinging arm,
A second swinging arm is swingably suspended via a swinging device, and a pinch roll of coating material that can be rotated is attached to the upper part of the first swinging arm and the second swinging arm. The gist is that a movable cutting device for cutting the coating material in the width direction is provided at the tip of each of the second swinging arms.

It is driven by

Therefore, when the drive motor 22 is driven to rotate, the frame 19 connected to one end of the chain 20 slides along the slide bear rig 15, and at this time, by driving the drive motor 18 to rotate, the rotary cutter 16 is rotated. It rotates and cuts the sheet-like coating material W in a predetermined direction.

Next, to explain the swinging devices of the first and second swinging arms 6 and 8, the upper end of the first swinging arm 6 is connected to the rod 24 of the power cylinder 23 installed on the support plate 3. and the second swing arm 8 has a second swing arm attached to the side wall of the swing arm 6.
It is connected to the rod of the book swing cylinders 25a, 25b.

When the coating material W is wound up to a predetermined length, drive motors (not shown) of the winding rolls 2a and 2b are stopped.

Next, the coating material rolling-in method of the present invention having the above-mentioned configuration will be explained.

First, before starting to wind up the coating material W, an operator sets the tip of the liner W1 around the cells 27 of the winding rolls 2a and 2b with a predetermined slack X.

In such a state, the tip of the coating material W supplied from a molding process (not shown) is
supply control device and pinch rolls 10, 11a,
11b for a predetermined length as shown in FIG. From this state, first, one swing cylinder 25a is contracted to swing the second swing arm 8 by a predetermined angle α using the support shaft 7 as a fulcrum as shown in FIG. As shown in Fig. 7, the power cylinder 23 is contracted and the first
The swinging arm 6 is swung by a predetermined angle α1 together with the second swinging arm 8 held at the constant inclination angle to a position where the tip of the coating material W passes over the cells 27.

From this state, the swing cylinder 25
a by a predetermined length, and the tip of the coating material W is controlled to be located between the cell 27 and the liner W1 as shown in FIG.

From this state, when the drive motor (not shown) is rotated to rotate the take-up roll 2a in the direction of the arrow, the tip of the coating material W is wound up by the frictional force between the liner W1 and the cells 27. In this state, the coating material W is sequentially wound up until it reaches the length set on the measuring device provided on the winding roll 2a. At this time, the diameter of the cell 27 gradually increases with the coating material W, so if the second swing arm 8 is stopped at a predetermined position, the coating material W will come into contact with the coating material W. By causing the swing cylinder 25a to contract at a predetermined speed in accordance with the winding speed, the second swing arm 8
rotates outward so as not to contact the coating material W, so that the coating material W and the second swinging arm 8
This prevents them from coming into contact with each other and allows smooth winding work. In this way, when the coating material W is wound up to a predetermined length on the winding roll 2a, the drive motor of the winding roll 2a stops,
At the same time, the drive motor 18 of the cutting device 14 starts driving, and the rotary cutter 16 starts rotating via the timing belt 17. Furthermore, at the same time, the drive motor 22 that slides the frame 19 starts rotating, and the frame 19 connected to the chain 20 moves to the slide bearing rig 15.
The rotary cutter 16, which is being rotated at this time, cuts the coating material W and the liner W.
Cut the terminal part of 1.

Note that during this cutting, the coat material W and liner W
1 is held under constant tension by the pinch rolls 11a and 11b, so when cutting with the rotary cutter 16, the end part becomes wrinkled and the cut surface does not become irregular, and the cut surface remains constant. The quality status of the product shall be maintained.

In this way, when the winding work of one winding roll 2a is completed, the power cylinder 23 and the swing cylinder 25a are moved so that the swing arms 6 and 8 are in the first position.
The tip of the coating material W supplied from the not-illustrated molding process is operated to be in the vertical state as shown in the figure, and the tip of the coating material W supplied from the not-illustrated forming process is passed through the coating material W supply control device and the pinch rolls 10, 11a, 11b. and send it out for the specified length.

From this state, the first and second swing arms 6, 8 are swung toward the other winding roll 2b via the power cylinder 23 and swing cylinder 25b,
The coating material W is rolled up while sandwiching the liner W1 in the same order as above.

Note that the other functions are the same as those of the winding roll 2a on one side, so explanations thereof will be omitted.

Further, the work of winding the coat material W onto the winding rolls 2a and 2b, the winding work of a predetermined length, and the cutting work are performed in an extremely short time, and for example, the end portion of the coat material W is The time from cutting to the next winding roll 2b is approximately 25 seconds.

By performing the operations as described above, the leading end of the coating material W can be rolled in and the end portion can be cut efficiently without the need for manpower.
