Description

[0001] Description [0002] Adhesive spread apparatus for zipper [

The present invention relates to a pressure-sensitive adhesive application device for a zipper, and more particularly to a pressure-sensitive adhesive application device for a zipper, which is disclosed in Patent Registration No. 1350719, The present invention relates to a pressure-sensitive adhesive application device for a zipper, which is capable of uniformly and stably performing a pressure-sensitive adhesive application operation by minimizing the work tolerances of the upper and lower application rollers.

As known, the zipper, which is also called a slide fastener, can be quickly opened and closed, and is used for a variety of products such as shoes, bags, as well as clothes.

Such a zipper is applied to a zipper tape of a zipper in order to precisely seal the skin complex (such as a garment, a bag, etc.), and the zipper is firmly attached to the zipper tape do.

In this case, since the conventional adhesive means for the zipper tape of the conventional zipper has arrived at the adhesive in such a form that an adhesive such as a bond is directly pasted on the zipper tape of the zipper using a brush, the adhesive efficiency of the adhesive is lowered, It was difficult to attach to the exact position of the zipper because the attachment state was poor when it was attached just before sealing the clothes complex, the bag, and the shoes which are skin complexes.

As one of the measures proposed by the present applicant to solve such a problem, Korean Patent Registration No. 1350719 (published on Apr. 14, 2014) discloses a technique related to an automatic dispensing apparatus for a zipper.

As shown in FIGS. 1 to 3, the automatic pressure application device for a zipper disclosed in the above-mentioned Japanese Patent No. 1350719 automatically applies a pressure sensitive adhesive applied to front and back sides of the zipper tape and both right and left side surfaces thereof through a mechanical application mechanism And the like.

That is, the automatic adhesive applicator for zipper includes a work table 100 having a table 110 structure having a foot part 120 capable of driving and controlling a coating operation state, And a coating device main body 200 capable of automatically applying a pressure-sensitive adhesive on the zipper tape.

The main body 200 of the applicator 200 includes a tank accommodating portion 210 in which a tank 211 for accommodating a viscous agent is embedded and a tank accommodating portion 210 disposed on a side surface of the tank accommodating portion 210, A nozzle assembly 230 disposed on one side of the tank 211 to transfer and dispense the pressure sensitive adhesive inside the tank 211; A pressure sensitive adhesive pad cover 240 for applying a pressure sensitive adhesive on the zipper tape of the zipper 300 through a pair of upper and lower application rollers 241 and 242, A zipper supplying unit 250 having a guide zipper guide rail 251 for guiding the motor and a motor mounting unit 260 for providing a driving force to the lower application roller 242 disposed on the side of the operation unit 220.

The upper application roller 241 is rotatably assembled to the bottom surface of the assembly body 231 of the nozzle assembly 230 through the roller assembly guide plate 244 so as to communicate with the discharge hole 232, The pressure sensitive adhesive in the tank 211 is fed through the inflow line S of the nozzle assembly 230 and discharged and supplied to the roller surface of the upper application roller 241 through the discharge hole 232. [

The lower application roller 242 is disposed so as to face the lower application roller 241 so as to rotate in a state in which the roller surface contacts the adhesive in the lower tank 243, 260 are connected to the operation motor 261 by a drive shaft 263 so as to be rotatable.

The adhesive in the tank 211 is fed to the roller surface of the upper application roller 241 through the inflow line S and the discharge hole 232 of the nozzle assembly 230, Is applied to the roller surface of the lower application roller 242 which rotates in a partially locked state in the lower tank 243 so that the zipper tape 300 of the zipper 300 passing between the upper and lower application rollers 241, The pressure-sensitive adhesive can be automatically applied to the pressure-sensitive adhesive layer.

That is, when the zipper 300 is supplied through the zipper guide rail 251 of the zipper supplying part 250, one end of the zipper 300 is brought into contact with the lower applying roller 242, When the lower application roller 242 is rotated by the driving force of the lower application roller 241 and the lower application roller 241 is rotated by the driving force of the upper application roller 241 and the lower application roller 241, As the zipper 300 passes between the upper and lower application rollers 241 and 242, the application of the pressure sensitive adhesive is automatically performed.

When the adhesive agent is not applied on the zipper tape of the zipper 300 during the application of the adhesive through the upper and lower application rollers 241 and 242 on the zipper 300 as described above, It is necessary to spread the gap between the adhesive layers 241 and 242 so that the adhesive is not applied.

Accordingly, in the above automatic zipper applicator for applying a zipper, it is possible for the operator to send a control signal for temporarily cutting off the coating operation through the operation of the footrest part 120, The gaps between the projections 241 and 242 are structurally widened so that the coating operation is not performed.

That is, the portion of the lower application roller 242, which is supported and fixed on the lower tank 243 through the up-and-down eccentric movement of about 10 mm in the lower tank 243 of the adhesive portion 24, is vertically and eccentrically moved, So that the gap between the upper application roller 241 and the lower application roller 242 can be opened.

3, a hinge turning part 245 is provided at one end of the lower tank 243 and an eccentric downward part 254 is provided at the lower surface of the lower tank 243 around the hinge turning part 245, And a height adjusting stopper 140 for adjusting the height of eccentric movement of the lower tank 243 in the vertical direction.

In addition, since the lower tank 243 is vertically and eccentrically moved by the operation of the cylinder 130, the lower application roller 242 supported and fixed to the lower tank 243 naturally moves up and down eccentrically The gap between the drive shaft 263 and the lower application roller 242 of the operation motor 261, which are mutually connected to provide a driving force to the lower application roller 242, is also affected by eccentric movement.

The driving motor 261 is fixed to the side of the operation panel 220 so that the driving shaft 263 of the driving motor 261 maintains a straight line with the center of the lower application roller 242 To be fixed at a constant height.

Therefore, in order to enable the center of the lower application roller 242 to be eccentrically moved downward, a connecting portion that can compensate the eccentric height between the lower application roller 242 and the drive shaft 263 is required. Due to this necessity, a separate joint portion 262 is provided on the path of the drive shaft 263 so as to automatically compensate the height of the drive shaft 263 in accordance with the upward and downward eccentric movement of the drive shaft 263.

However, due to the above-described structural features, in the case of the automatic adhesive applicator disclosed in JP-A-1350719, when the operation of separating the upper and lower application rollers 241 and 242 is repeated, And the upper application roller 241 is fixed via the eccentric movement of the lower tank 243 to the lower application roller 241. In this state, When the upper and lower application rollers 242 and 242 are engaged with each other while tension is applied to one side of the lower tank 243, the gap is shut off, and the work tolerance is severely generated .

The process of applying the pressure-sensitive adhesive on the zipper using the apparatus for applying a pressure-sensitive adhesive for a zipper according to the present invention and the operation and effects thereof will be described in brief as follows.

First, the working conditions necessary for applying the pressure-sensitive adhesive 4, such as the heater temperature, the pneumatic pressure, and the operating mode, are set through the operation panel 90 of the zipper applying apparatus A for zipper according to the present invention.

When the zipper 3 requiring the application of the pressure sensitive adhesive 4 is prepared, the upper and lower application rollers 41 and 42 and the zipper supplying portion 70 The width of the guide rail 71 is adjusted appropriately.

The first cartridge heater 27a and the second cartridge heater (not shown) are operated by heating in the state where the solid hot melt of the pressure sensitive adhesive 4 is put in the upper tank 20 and the lower tank 60, Is melted and prepared in a liquid state.

When the preparation is completed, the zipper 3 is supplied through the guide rails 71 of the zipper supplying unit 70.

That is, when the user presses the footsteps 14 and sends an operation start signal, the cylinder 51 of the ascending / descending section 50 is operated to lower the upper application roller 41 so that the upper and lower application rollers 41, The operation motor 81 starts to be driven to rotate the lower application roller 42. In this case,

When the zipper 3 is fed along the guide rails 71 in a state of being engaged between the upper and lower application rollers 41 and 42, the upper and lower application rollers 41, The lower application roller 42 is rotated by the driving force of the operation motor 81 so that the upper application roller 41 is free to rotate in response to the rotation of the lower application roller 42, So that the zipper 3 is automatically advanced.

At this time, the pressure sensitive adhesive 4 received in the upper tank 20 is transported and discharged along the transfer line and dispersedly applied to the roller surface of the upper application roller 41, and the pressure sensitive adhesive contained in the lower tank is transferred to the upper surface of the lower application roller 42 It is buried on the roller surface.

Since the lower application roller 42 is rotationally driven in a state partially embedded in the lower tank 60, the pressure sensitive adhesive 4 contained in the lower tank 60 is naturally buried in the roller surface of the lower application roller 42 .

Therefore, since the hot melt, which is the adhesive 4, adheres to the roller surfaces of the upper and lower application rollers 41 and 42, the adhesive 4 is naturally coated on the surface-contacting zipper 3, The zipper 3 is supplied along a straight line along the guide rail 71 so that the application work can be accurately and cleanly applied to the zipper 3 where the adhesive 4 needs to be applied.

At this time, the adhesive conveyance distance from the ejection hole 26 of the upper tank 20 to the ejection hole 47 on the upper application roller 41 is smaller than that of the adhesive conveyance line disclosed in the prior art publication No. 1350719 Since the vertical transfer path and the horizontal transfer path are mixed with each other, there is a fear that the liquid pressure-sensitive adhesive 4 is cooled and hardened during the process of transferring the pressure-sensitive adhesive 4, thereby hindering smooth transfer.

In the present invention, an auxiliary heater (not shown) is provided in the auxiliary heater hole 49 on the application roller mounting plate 45 so as to maintain the liquid state by heating the adhesive 4 again in the process of transferring the adhesive, It is preventing the problem in advance.

On the other hand, in the apparatus A for applying a pressure-sensitive adhesive for a zipper according to the present invention, if there is a portion on the zipper 3 which does not need to be coated with the pressure-sensitive adhesive 4, So that the application of the adhesive 4 is carried out only in a portion where application is required.

That is, when the portion where the adhesive 4 does not need to be applied passes between the upper and lower application rollers 41 and 42 in the process of applying the adhesive 4, the upper application roller 41 is moved from the lower application roller 42 So that the pressure-sensitive adhesive 4 is not applied.

When the user releases the pressing state of the foot part 14 and sends the set driving signal to the user, the operation of the piston 52 in the cylinder 51 of the ascending / descending part 50 causes the upper application roller 41 to move instantaneously The upper application roller 41 is separated from the lower application roller 42 while being engaged with the lower application roller 42 so that the application of the adhesive 4 on the zipper 3 is not performed.

 In this state, the user moves the zipper 3 to move the portion of the zipper 3 that does not need to apply the adhesive 4 past the adhesive patch 40, and then the adhesive 40 4) When the zipper 3 required to be coated is aligned, the user presses the foot part 14 again to transmit a descending signal to the cylinder 51 of the ascending and descending part 50, So that the surface contact state of the zipper 3 is maintained. Thus, the above-described coating operation is repeatedly performed.

 In this way, the user can divide the portion required to be coated on the zipper 3 and the portion not required to be coated through the method of depressing the presser foot portion 14 or releasing the pressurized state, and proceed the application work.

As described above, according to the present invention, the pressure sensitive adhesive 4 is automatically applied as it passes between the upper and lower application rollers 41 and 42 where the pressure sensitive adhesive 4 is applied to the roller surface while the zipper 3 is driven to rotate It is possible to increase the productivity of the zipper 3 by applying the pressure-sensitive adhesive 4 to the zipper 3 in comparison with the application work by hand, Uniform application of the pressure-sensitive adhesive 4 is possible even if an expert is working.

Particularly, in the present invention, in controlling the ascending / descending state of the upper application roller 41 in accordance with operating conditions such as operation and stop in the ascending / descending section 50, the ascending / descending plate 54 and / The application roller mounting plate 45 can be raised and lowered in a balanced and stable manner through the support rods 55 on both sides and the height of the lower application roller 41 can be finely adjusted by using the height adjusting nut 56 It is possible not only to minimize the work tolerance due to the engagement of the upper and lower application rollers 41 and 42 with respect to the zipper 3 but also to reduce the work area of the lower tank 243 disclosed in the prior art publication No. 1350719, The lower application roller 242 is separated from the upper application roller 241 in the state where the upper application roller 241 is fixed through the movement of the lower application roller 242. In addition, On structure It has the advantage of being able to perform relatively very stable job.
