The present invention relates to a device used in the adhesion process of the shoe, and more particularly, a hot melt that can adjust the amount of hot melt applied to the adherend, the length of the brush brush to form a coating pattern on the adherend It relates to a shoe bonding apparatus used.

In general, the sole of the shoe is an out-sole made of rubber material to be abrasion resistant and slippery as a part which is closed to the ground, and a synthetic resin material which is easily bonded to the upper part of the outsole to reduce weight and absorb shock. It consists of a foam-expanded mid-sole.

As such, the conventional bonding process of firmly bonding the outsole and the midsole constituting the sole of the shoe is performed by the operator applying the adhesive to the toothbrush brush, and then the upper surface of the outsole (or the back of the midsole) laid at predetermined intervals in the work line. Apply by hand and glue.

However, such a conventional shoe bonding process has a problem in that the production efficiency is lowered because the operator has to apply the adhesive to the toothbrush brush applied to each one.

Moreover, since the adhesive used in the conventional shoe bonding process uses a solvent-type adhesive (or water-soluble adhesive) that is harmful to the human body, the worker's working environment is poor, and a separate drying process is performed after the solvent-type adhesive is applied. Only through the midsole and the outsole is also possible to bond.

In order to solve this problem, the pre-registered hot melt heating melting and coating device (registration number; 20-0347378) has a hot melt heating melting device for heating and melting solid hot melts and a rotating function by receiving the hot melt melted from the hot melt heating melting device. It consists of a hot melt coating device for applying a hot melt through a brush having a.

In this way, the conventional hot melt heat dissolving and coating apparatus configured is harmless to the human body because it does not generate a solvent because it uses a hot melt, a solvent-free adhesive as an adhesive, and also does not perform a separate drying process by using a solvent-free adhesive. You can glue the midsole and outsole directly.

In addition, since the hot melt is melted in the liquid phase at room temperature and the molten hot melt is supplied to the brush, a series of processes are automatically controlled by the hot melt heating apparatus and the hot melt coating apparatus, thereby enabling rapid work progress.

In addition, the brush is discharged hot melt is rotated by the power supplied, which allows the operator to proceed more quickly by applying the hot melt according to the application pattern having a predetermined direction on the application surface of the outsole. That is, when a worker applies a predetermined force to the bottom of the rotating brush in contact with the outsole, the discharged hot melt is buried in the curved brush by the applied force. Thereafter, the operator moves the outsole in a constant direction to obtain a discharge pattern of the hot melt.

However, in spite of these advantages, the conventional hot melt heat dissolving and coating device is impossible to control the hot melt discharged through the rotating brush during the bonding process of the shoe. Not only can not control the application amount of the hot melt melted over the work process line will be buried. This not only provides a waste of resources and a dirty working environment due to over-discharging of the hot melt, but also causes a waste to be periodically cleaned of dirty working places.

In addition, since the hot melt discharged through the rotating brush has a large temperature range between 100 ° C and 180 ° C depending on the type, heat resistance and durability are required. For this reason, the brush brush which is bent by the force applied by the operator to obtain a uniform coating pattern does not use a synthetic resin and uses natural animal hair.

In this case, when the temperature range of the hot melt is small (e.g., 100 ℃), it is suitable to use the brush length longer.If the temperature range of the hot melt is high (e.g., 180 ℃), the brush brush It is suitable for the work process to use the small length of the brush. However, since the conventional brush is integrally installed in the hot melt coating device, the length of the brush brush cannot be adjusted. Deformed brush brush is severely deformed. Moreover, when the deformed brush brush is used continuously in the workplace, there is a problem of shortening the replacement cycle of the brush because it affects the coating quality (shape of the coating surface, coating thickness) of the hot melt.

In addition, depending on the physical properties of the hot melt (viscosity, flowability, moisture reaction degree) should be used to adjust the brush length to obtain the optimum coating pattern. In other words, when using high viscosity hot melt brush brush length should be short to minimize the deformation of the brush brush can be used for a long time, when using a low viscosity hot melt brush brush length should be long to increase the area of the application pattern to expedite work It is possible to proceed, the length adjustment means in the conventional brush is impossible to obtain the above-mentioned advantages.

The present invention is to solve the problems of the prior art, the object of the present invention is provided with a drive control means for adjusting the application amount of the hot melt to be applied to the adherend, to discharge and use only the optimal amount of hot melt required for the bonding process By saving resources and controlling the amount of hot melt discharged as necessary, it is possible to provide a shoe bonding apparatus using a hot melt that provides a work environment by preventing hot melt from being buried around a work line.

Another object of the present invention is provided with a length adjusting means for adjusting the length of the brush brush, shoes using a hot melt to perform the bonding process by adjusting the length of the brush brush according to the use temperature and physical properties of the various hot melt that is the adhesive used An adhesive device is provided.

Here, the heating block 220 is divided into an upper heating block 220a and a lower heating block 220b, and a cartridge heater and a temperature sensing sensor are provided in the divided heating block 220 to be melted during work. The receiving part 240 and the hot melt inflow control part 260 are always maintained at a constant temperature so that the hot melt does not cause phase transformation into a solid phase.

In addition, the brush 210 has a third through-hole 211 is formed in the center so that the hot melt supplied from the end of the hot melt inflow intermittent portion 260 is discharged to the outside, the brush brush radially on the edge of the bottom surface 212 is fixedly installed, a male thread portion is formed on the outer circumference, and the height adjusting cap 215 on which the female thread portion 214 is formed on the inner circumference is fixed to the male thread portion 213 of the formed outer circumference. It is provided.

The hot melt injection device 200 and the frame 300 is connected to the intermediate shaft gear 280 fixed to the other side of the heating block 220 and the intermediate shaft gear 280 is installed laterally connected As the drive shaft gear 320 is fixedly installed on one side of the frame 300, and the drive shaft coupling 330 is connected to the upper portion of the drive shaft gear 320, the drive shaft coupling 330 The upper portion of the drive shaft 340 for transmitting power to the brush 220 is rotatable through the intermediate shaft gear 280 and the drive shaft gear 320.

As such, the shoe bonding apparatus using the hot melt of the present invention is configured to proceed with the operation of the outsole and the midsole, when the power is first applied to the shoe bonding apparatus, the applicator 100 melts the solid hot melt filled in the tank After heating to a predetermined temperature so as to melt, the molten liquid hot melt is flowed through the flow hose 310 to the inlet 230 provided in the upper heating block 220a.

Hot melt of the liquid flowing through the inlet 230 is received from the hot melt inlet 260 connected to the receiving unit 240. Here, the open end of the second through hole 261 constituting the hot melt inlet control unit 260 is closed by the other end of the hot melt inlet control rod 410 to enable the filling of the flowing hot melt.

Thereafter, the operator places the outsole S placed on the work line L in the vicinity of the brush 220 to apply hot melt to the surface of the outsole S (or the midsole), and then turns on the driving switch. When the electric signal is supplied to the solenoid valve 420, the solenoid valve 420 injects air into the hot melt discharge control valve 430.

The hot melt discharge control valve 430 raises a part of the hot melt inflow control rod 410 by the pressure of the injected air, thereby moving the hot melt inflow control rod 410 upward.

As a result, the end of the hot melt inflow control part 260 sealed by the other end of the hot melt inflow control rod 410 is opened and the liquid hot melt accommodated is flowed into the third through hole 211 of the brush 210 so that the outsole ( Supplied to the coated surface of S).
