Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a sealing tape adhesion device for applying thermal adhesive tape along the seams of sewn materials such as wet suits used for diving. It is something.

(b) Prior art In general, when sewing a wetsuit or the like using a synthetic fiber sheet or synthetic resin sheet as a material, after sewing with a sewing machine, a seal is used to prevent water leakage and to strengthen the seam (seamed portion). Apply tape along the seam.

This work is usually done by spraying hot air onto the heat-melting adhesive applied to the back side of the sealing tape, melting the adhesive in advance, and attaching the sealing tape to the seam of the material to separate the material and tape. The seal tape is fed between a rubber roller and a metal roller such as iron to continuously adhere the seal tape along the seam.

By the way, when using this type of device to seal along the armholes, which are the joints between the waist and sleeves, or along the joints in the length direction of sleeves and crotches, it is difficult to compare the areas. Unlike when machining a wide, flat part, for example, when sealing an armhole, it is necessary to seal in an annular shape along the circumference of the armhole. , a cylindrical cylinder part with a processing part, in this case a pressure roller, is required at the tip, and in sealing the joints in the length direction of the sleeves and crotches, Since it is necessary to seal the material continuously, the arm is equipped with a processing section, in this case a pressure roller, at the tip of an arm-type sewing machine, and is arranged along the feed direction of the material. Depending on the area to be sealed, etc.
Specialized machines were used for each process, and the sealing process was performed in separate steps, resulting in an increase in equipment costs and man-hours.

(c) Purpose of the invention This invention was made with attention to the above-mentioned circumstances, and its purpose is to improve the armholes, which are the joints between the waist and sleeves, the sleeves, the crotch, etc. An object of the present invention is to provide a sealing tape adhesion device that allows continuous sealing of joints along the length of a cylindrical portion using the same device.

(d) Structure of the invention In order to achieve the above object, the present invention is characterized by the following structure.

That is, in a seal tape bonding device in which a sheet-like material is fed with adhesive tape between a pair of rollers, and the adhesive tape is pressed onto the material while being pinched by the rollers, the roller is a common roller. , consisting of a first roller and a second roller that are in pressure contact with this common roller, the first roller is provided at the tip of a cylinder section disposed in a direction perpendicular to the direction of movement of the material, and the second roller is provided The roller is provided at the tip of an arm disposed along the direction of movement of the material, and the cylinder and arm are rotated by a drive source to select the first and second rollers as the common roller. This is a seal tape adhesion device that allows for pressure contact.

(E) Embodiment Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings.

Figures 1 and 2 show an overall overview of the seal tape adhesion device, in which 1 is the main body housing housing various drive sources such as motors and air cylinders, power transmission mechanisms, etc., and 2 is the main body housing. An arm 3 integrally projecting from part 1 in the horizontal direction is a common roller provided at the tip of arm 2 so as to be movable up and down. This common roller 3 has a shaft 6 which is driven up and down by the operation of a lever 4 (shown in FIG. 5) or a pedal 5.
The arm 2 is rotatably supported at the lower end of the arm 2 via a bracket 7, and is rotationally driven via a power transmission mechanism (not shown) disposed within the arm 2. Further, the common roller 3 is made of iron, and a heater is housed inside.

By the way, the cylinder part 10 and the arm part 11 are rotatably arranged in the main body casing part 1, and the main body casing part 1
It can be rotated within a predetermined angle by a drive source such as an air cylinder disposed inside.

That is, the cylinder section 10 has an arm 13 attached to the tip of the drive shaft 12, and the arm 13 is attached to the tip of the drive shaft 12.
A cylindrical cylinder 14 is attached to the tip of the shaft 14, and a pressurizing shaft 15 having the same diameter and having an outer periphery made of silicone rubber or the like is attached to both ends of a shaft 15 which is rotatably supported within the cylinder 14. Rollers 16 and 17 are attached.

One of the pressure rollers 16 serves as a first roller that selectively presses against the common roller 3, and by rotating the arm 13, the two pressure rollers 16 in FIG.
Arrow A in the figure is located between the standby position shown by the dotted chain line and the operating position where the common roller 3 is pressed against the common roller 3, as shown by the solid line.
It is designed to be able to move back and forth as shown in the figure.

The other pressure roller 17 comes into pressure contact with a drive roller 18 provided protruding from the side wall of the main body casing 1 at the position where the pressure roller 16 comes into pressure contact with the common roller 3, and is driven by the drive roller 18. It rotates. A cover 19 covers the drive roller 18.

The arm 13 is rotated using an air cylinder or the like disposed inside the main body housing 1 as a driving source.

Further, the arm portion 11 is attached to the tip of a cylindrical rotation shaft 20 that projects horizontally from the side wall of the main body housing portion 1.
It is perpendicular to the rotating shaft 20 and is integrally provided along the material feeding direction. This arm portion 11 rotatably supports a pressure roller 21 as a second roller at its tip, and this pressure roller 21 is supported on the rotating shaft 21.
It is configured to be rotationally driven by a drive source disposed within the main body casing 1 via a shaft 22, a timing belt 23, etc. provided within the main body casing 1.

Further, the rotation shaft 20 is rotated within a predetermined angle by an air cylinder or the like disposed inside the main body casing 1, and the pressure roller 21 is placed in the downward waiting position shown by the solid line in FIG. It is designed to be able to reciprocate as shown by arrow B in the figure between the position and the operating position where it comes into pressure contact with the common roller 3 as shown by the two-dot chain line.

Incidentally, the cylinder portion 10 and the arm portion 11 are operated simultaneously by the switching operation of a changeover switch provided on the pedal 25 or the operation panel 26, when sealing a cylindrical material such as an armhole in the circumferential direction. In this case, the state is changed to the state shown in FIG. 2, and when sealing is to be performed along the length of a cylindrical portion such as a sleeve portion or a crotch portion, the state is changed to the state shown in FIG. 1.

In addition, there is a hot air jet nozzle 3 on the front of the tip of the arm 2.
0 is set. This hot air jet nozzle 30 is used immediately before sending the thermal adhesive tape 32 (synthetic resin tape coated with a hot melt adhesive on the back side) loaded onto the reel 31 between the common roller 3 and the pressure roller 16 or 21. Then, hot air is sprayed onto the adhesive applied to the tape to heat and melt it.

This hot air injection nozzle 30 has a pin 34 attached to one end of a rotating arm 33 provided on the front side of the tip of the arm 2.
By rotating the rotating arm 33, it can be alternately switched between the diagonally upward standby position shown by the two-dot chain line and the operating position shown by the solid line in FIG. It is provided. In its operating position, the tip 30a of the hot air jet nozzle 30 is located immediately before the common roller 3 and the pressure roller 16 or 21 roll into contact with each other, as shown in FIG.

Further, a guide member 35 having a curved guide surface is attached to the tip 30a of the hot air injection nozzle 30, and the hot air injected from the tip of the hot air injection nozzle 30 is guided to the thermal adhesive tape 32 side and then to the material 36 side. I'm trying to prevent it from being sprayed. This is because when the hot air sprayed from the hot air spray nozzle 30 hits the material directly, the material itself expands and contracts locally, causing wrinkles.

Compressed air is supplied to a mouthpiece 37 at the upper end of the hot air injection nozzle 30, and the compressed air is heated to a required temperature by a heating section 38 having a built-in heater.

Further, reference numeral 40 in the figure represents a stopper for regulating the rotational position of the cylinder portion 10.

According to such a configuration, when sealing is performed along the circumferential direction of a cylindrical material such as an armhole, first, as shown in FIG. 11 to the standby position.

In this way, as shown in FIG. 5, when the thermal adhesive tape 32 is attached to the seam of the material 36 and fed between the common roller 3 and the pressure roller 16, a continuous seal is created as shown in section D in FIG. 6. Can be processed.

Next, when sealing is performed along the longitudinal joints of the sleeve b and crotch c, the cylinder part 10 is switched to the standby position and the arm part 11 is switched to the operating position, as shown in FIG. .

In order to insert the cylindrical material 36 into the arm 11, the common roller 3 is made to stand by in the upper position by operating the lever 4 or the pedal 5, and a gap is created between the common roller 3 and the pressure roller 21. Secure and in this state,
Insert the cylindrical material 36 to the front side of the arm 11, apply the thermal adhesive tape 32 to the seam of the material 36, lower the common roller 3 again, and attach the material 36 and the thermal adhesive tape 32 to the common roller 3. and the pressure roller 21.

In this way, while the cylindrical material 36 is being sent behind the rollers 3 and 21, the thermal adhesive tape 32 is continuously adhered along the seam.

In addition, when sealing is applied to a joint part of a flat part with a wide area such as the trunk part a, it is possible to continuously seal by switching the cylinder part 10 and arm part 11 to the state shown in FIG. 2. Can be sealed.

(f) Effects of the invention Therefore, according to the invention, even if sealing is done in an annular shape at armholes, etc., or sealing along the length of a cylindrical material such as sleeves and crotches, , by alternating between the cylinder part and the arm part, sealing can be performed continuously with one device.
There is no need to install a dedicated machine or separate the work into separate processes, as in the past, and equipment costs and manufacturing costs can be significantly reduced.
