Description

Description: TECHNICAL FIELD The present invention relates to a taping device for coating a joint portion such as a web or a strip.

(Prior Art) Webs, strips, etc. are joined and wound on rolls.

However, since the joint portion of the strip or the like is a convex portion, for example, the roll or the like of the process line is damaged.

Therefore, conventionally, the convex portion is covered with tape by hand or by using a taping device described below.

There are two types of conventional taping devices, a crimp bar system and a crimp roll system.

For the crimp bar type, as shown in FIGS. 3 and 4,
A pair of upper and lower crimping bars 32a, 32b in the width direction of the strip 31
The lower crimp bar 32b and the lower surface of the upper crimp bar 32a.
Set the tapes 33a and 33b on the upper surface of the
Taping is performed via the crimping bars 32a and 32b by operating the 4a and 34b.

On the other hand, the crimp roll type, as shown in FIGS. 5 and 6, is composed of carriages 43a and 43b which are moved in the width direction of the strip 42 by traveling devices 41a and 41b. And each carriage 43
a and 43b are tape feed rolls 44a and 44b and crimp roll 45, respectively.
It is provided with a, 45b and cutters 46a, 46b. Crimping roll 45a, 45
The b can be brought into contact with and separated from the crimping devices 47a and 47b, and can be rotated in a direction in which they are pressed against each other by the drive devices 48a and 48b.

Therefore, when the joining portion of the strip 42 reaches a predetermined position, the crimping braces 45a and 45b are crimped to move the traveling device 41.
While the carriages 43a and 43b are integrally moved by a and 41b, the upper and lower surfaces of the joint portion are adhered and covered by the tapes 49a and 49b wound around the tape feed rolls 44a and 44b. When the taping is completed, the tapes 49a and 49b are cut by the cutters 46a and 46b to complete the tape attachment. After that, crimp rolls 45a, 45
b is separated from each other, and the carriages 43a and 43b are returned to their original positions to prepare for the next taping.

(Problems to be Solved by the Invention) However, there is a problem that it takes too much time to perform taping manually by hand as in the conventional case.

On the other hand, when using the pressure-bonding bar type taping device, it takes time to set the tapes 33a and 33b on the pressure-bonding bars 32a and 32b, and the work is complicated because the tapes must be set every time. In addition, automatic operation is not possible,
There is a problem that work is dangerous.

When using the conventional pressure roll type taping device, when the tapes 49a and 49b are attached, the strip 4
Since the end of 2 is not supported at all, the strip 42
A lateral load is applied to the pressure bonding rolls 45a and 45b, which makes it necessary to drive them.

Furthermore, after taping the strip 42, in order to perform the next taping, it is necessary to return the carriages 43a and 43b to the original positions one by one, and accordingly, the crimp rolls 45a and 45b.
It has to be moved up and down, and the operation is troublesome.

In addition, since a power source for rotationally driving the pressure bonding rolls 45a, 45b is required, the structure of the device becomes complicated and not only becomes expensive, but there is also a problem that there is a lot of waste in the work.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a taping device having a simple structure, low cost, and good working efficiency.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a structure of a taping device, which is orthogonal to the conveying direction of the strip-shaped material, and has guide rails vertically provided so as to sandwich the strip-shaped material. , Two carriages provided on the respective guide rails and moving in synchronization with each other,

The cutter holder disposed in the above is configured by a cutter means including a guide bar provided at the pass line position of the band-shaped material and cutters provided on both sides of the guide bar.

(Operation) The trolley and the turntable mounted on the trolley move freely on the guide rail in a vertically synchronized manner, and in the turntable, the tape supplied from the tape feed roll by the press roll is guided by the guide bar. , Bonded parts of strips and guide bar are bonded in this order. Then, when the bonding is completed, the respective parts are separated by the cutter means, and the turntable is rotated 180 ° to prepare for the next taping.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

As shown in the figure, the taping device according to the present invention is roughly composed of a guide rail 3, a carriage 10, a turntable 11,
It comprises a cutter means 20.

The guide rails 3 are erected on both upper and lower sides of side plates 2 and 2 which face and stand upright on the base 1.
The guide rails 3 are above and below the strip 24, which is a strip-shaped member, and are orthogonal to the transport direction.

The carriages 10 and 10 are attached to the upper and lower guide rails 3 and 3, and are integrally moved along the guide rails 3 and 3 by the first ball screws 4 and 4, respectively. That is, the first ball screws 4 and 4 have pulleys 5 and 5 at their shaft ends, and a belt 6 is wound around the shafts of both pulleys 5 and 5 and the motor 7, The first ball screws 4 and 4 are simultaneously rotated by the driving of, and the carriages 10 and 10 are synchronously moved.

The turntables 11 and 11 are trolleys 10 and 10, respectively.
The turntable 11 is mounted on the turntable 11 so as to be horizontally rotatable and opposed to each other. The turntable 11 is provided with a tape feed roll 13 and a press roll 14 via mounting plates 12 and 12.
