The present invention relates to a self-adhesive adhesive extruder for use in sewing seam seam shears, which was previously filed with the invention application 89-10610.

Since the seam seam seam is made to perform the function of dividing the seam seam on both sides and presses it, it is necessary to apply the seam seam by hand and apply mechanical adhesive work to the seam seam by hand. Was. Therefore, the cumbersome manual process must be performed in parallel, so that efficient work cannot be expected. When the adhesive is applied by hand, the adhesive is not uniformly applied because it is not applied much more or less than necessary. There was a problem such as that.

The present invention was devised to solve such a problem, and provides an automatic adhesive extrusion device configured to perform a simple and efficient seam welding operation by automatically extruding the adhesive during the mechanical seam processing by the seam cutting machine. Its purpose is to describe in detail based on the accompanying drawings as follows.

The present invention is first mounted on the upper holder 21 of the seam allowance sorter 20 of the present invention, as shown in Figure 2, as shown in Figure 1 the projection 2 in the front center of the substrate (1) A vertical rod (3) having a seam allowance (4) on the front side of the front and rear sides of the projection (2), and the leaf spring (5) on both sides of the protrusion (2) The two operation bars 6 arranged to face each other are elastically installed, and the nozzle extrusion nozzle 7 is screwed inwardly at a predetermined angle through the lower guide hole 6a of the operation bars 6, On the front of the projecting portion 2 on which the vertical rod 3 is placed, the guide support piece 8a is screwed to the seam guide 8 to which the speech is delivered, thereby guiding the seam to the correct position.

An inclined bent jaw 10 in which an outwardly bent portion 6 'is formed at the upper end of the operation section 6, and a bolt 9 screwed thereto is the tip of the automatic plate 10 arranged on the upper surface of the substrate 1. The operation section 6 is configured to be operated by the operation of the operating plate 10 elastically installed by the spring 11 in contact with ').

The nozzle 7 screwed to the lower end of the operation rod 6 is connected to the adhesive pressure feed hose 12, the air pressure hose 13 of the air cylinder (not shown), and the air drying hose 14 for the adhesive drying. The adhesive pressure feed hose 12 is connected to the adhesive storage tank 15 as shown in FIG. 1, and the air pressure injection hose 13 and the air drying hose 4 for drying the adhesive are connected to the air cylinder. In addition, the air pressure of the cylinder is transmitted to the inside of the tank 15 through a hose 16 connected between the air cylinder and the adhesive storage tank 15 to pressurize the adhesive to the nozzle 7.

As shown in (a) and (b) of FIG. 3, the nozzle 7 for extruding the adhesive is an extruded hole 7a at the tip of the nozzle 7 by the elevating operation of the needle valve 16 by electrical operation. ) And the needle valve (16) is extruded through the extruded hole (7a) opened in the state of (a) the needle valve 16 is raised during the seam welding operation, the needle valve (16) ) Is lowered to close the extrusion hole 7a in the state of (b) and is configured to stop the extrusion of the adhesive.

Referring to the operating state of the present invention based on Figure 4, the upper holder 21 is lowered by the mechanical operation of the seam allower 20, the upper side is indicated by the tension control case (symbol 22 in Figure 2) As the gap between the openings is widened, the operation plate 10 is lifted up by the trailing end of the spring 11, and the inclined bent jaw 10 'of the tip is lowered as shown in (b). Likewise, by pressing the upper outwardly bent portion 6 'of the operating rod 6 arranged on both sides of the front surface of the substrate 1, the operating rod 6 is rotated toward the vertical rod 3 (at the time of operation ( 6) is in a state of pressing the leaf spring (5). Therefore, the nozzle 7 screwed in between the operation | movement 6 is also rotated together, and the front-end extrusion hole 7a comes close to seam a.

On the other hand, the seam allowance (a) of the product placed on the slider 23 is inserted between the two guide support pieces (8a) of the seam allowance guide (8) to be in a standing state, so that the adhesive extruded through the nozzle (7) is erected. It is applied to the outside of the seam allowance (a), that is, the adhesive surface, and presses the product while pressing and spreading the seam allowance (a) by the up and down rollers 24 and 25 shown in FIG. It is to be made.

In addition, when the work is finished, when the upper holder 21 of the seam allower 20 is raised, the rear end of the operation plate 10 is pressed against the tension control case 22 and the inclined bent jaw 10 'of the tip is raised. As shown in (a) of FIG. 4, the operating section 6, which receives the rebound force of the leaf spring 5, rotates to the outside, and the nozzle 7 at the bottom thereof also opens to the outside. Away from the sphere 8, the nozzle 7 is in the state of FIG. 3 (b) to close the extrusion hole (7a) to prevent unnecessary leakage of the adhesive.

The present invention is to handle the seam seam of the seam seam sewn by connecting the leather or cloth as described above by the mechanical operation of the seam seam, the invention of the earlier application, by automatically extruding the adhesive, more easily and quickly and efficiently It is possible to achieve a good quality of adhesion because there is almost no defect rate because the adhesion state of seam seam is good, and it provides very practical and economical effect that can greatly reduce manpower and time required for seam seam processing work.

Claims (1)

Insert the vertical bar (3) having the seam allowance (4) in the front center projection (2) of the plate (1) to guide the combination of the seam guide (8) with the guide support piece (8a) in front The seam allowance mouth 4 is positioned between the support pieces 8a, and plate springs 5 are provided on both sides of the protruding portion 2 so as to resiliently operate the operation section 6 opposed to the substrate 1 on both sides. And a working plate 10 having a tip slope bending jaw 10 'that presses the upper outward bending portion 6' of the operating rod 6 to operate the operating rod 6, and the upper portion of the substrate 1 Installed in the spring by the spring 11 connected to the rear end thereof, and the adhesive pressure hose 12, the air pressure hose 13, and the adhesive drying air hose 14 are connected to the lower end of the operation section 6, respectively.
