Description

[0001] The present invention relates to a supersonic type hammering device for upper shoe,

The present invention relates to an ultrasonic shoe upper hammering apparatus for improving work efficiency by improving the work environment in shoe upper wrinkle and sewing line hammering work of a shoe manufacturing process, protecting the health of workers, and improving the quality of shoes.

In order to strengthen the adhesion and quality between the upper and the insole in the shoe manufacturing process, the hammering work is performed by sewing the upper and lower insole of the upper part of the shoe in a strobel (zigzag-shaped sewing) And a large amount of rough irregularities generated during the sewing process.

The ultrasonic shoe upper hammering apparatus of the present invention uses an ultrasonic vibration apparatus for eliminating high-pitched sound generated during the hammering operation in the prior art system, preventing vibration of the vibrator from affecting the body, and improving work efficiency .

In addition, the universal joint enables the user to freely move the shoe last in the direction of the work site to the right and left and to the front and back of the shoe, and in the hammering operation, regardless of the shape and size of shoes such as High, Low, Men, Woman and Kid And an upper bumper fixing jig capable of supporting the shoe last.

The most important part in the production of shoes can be divided into two major parts, the shoes are sewn on top and bonded.

Particularly, the adhesion between the bottom of the upper part and the insole is not only different from each other, but also the upper part of the upper part is composed of one layer, two layers or three layers depending on the part, resulting in the protrusion (jaw) There is a problem in that it is difficult to adhere by the adhesive due to the wrinkling phenomenon and the rough uneven state coming from the sewing of the strobes between the lower end of the upper part and the circumference of the insole.

The process of solving this problem is called "hammering". In the past, hard hammers were used to tap the upper, but nowadays, pneumatic vibrators are used as hammering devices.

In the conventional hammering work, a shoe last having a shoe upper is inserted into a last fixing pin formed on a plate mount, and then fixed with a bumper pedestal. The operator holds the shoe upper with one hand and the pneumatic vibrator And the wrinkle and the uneven portion were easily formed by the force of the vibration friction while closely moving along the wrinkle or the sewing portion.

Such a conventional technique uses a force that vibrates the ball vertically and horizontally by supplying pneumatic pressure to a ball formed inside the pneumatic vibrator. The tremendous vibration noise generated at this time generates a large noise at a work site, And vibration friction is continuously transmitted to the palm, wrist, elbow, and shoulder of the worker, and the movement of eating at meal time is shaken to such an extent that it affects the muscles and the fracture, which is a cause of the musculoskeletal industrial disaster.

Also, in the work process, since it is performed only by the pure vibrating force of the vibrator, it is impossible to perform the hammering work for picking up the wrinkles of the nose and the heel due to the limitation of power, so that the steam is sprayed first before the rusting And the strobeed insole area (bottom area) should be trimmed secondarily after the rinsing, and the troublesome process of finishing the third part of the defective part in the first operation there was.

In addition, the quality level of the surface condition that is easy to do in the strobel hammering work is insufficient, and the upper part of the shoe upper part is overlapped with the double layer or the triple layer, and the upper part of the embossed fabric such as double mesh etc. There is no method, and when the insole is adhered in the embossed state, not only the time and the amount of application of the adhesive are increased but also the working efficiency is lowered, and the problem of the external appearance and the quality of the adhesive is raised.

In the past, the shoe industry has been largely dependent on manual work, and nowadays it has been developed in many fields in order to improve the work environment such as computer sewing machine, automatic press, safety and quality of workers, but the hammering work has yet to be solved, It does not meet the regulations.

It is an object of the present invention to solve the above-mentioned problem, and it is an object of the present invention to prevent the audible disturbance of a worker by eliminating the noise at the work site, to prevent the vibration friction of the vibrator from affecting the body of the worker's hands, muscles, joints, And an object of the present invention is to provide an ultrasonic shoe upper hammering apparatus which satisfies the 5S requirement.

In order to achieve the above-mentioned object, the present invention relates to a method of manufacturing a shoe sole, comprising the steps of: forming an upper part of a nose and a heel part of the upper part of a shoe manufacturing process and a rough part of an uneven shape of a strobel sewing line part, Wherein the vibration hammer device hitting the upper part along the corrugation and strobel sewing lines of the upper part of the nose and heel parts is free from noise due to the vibration sound, And an ultrasonic vibrator having no impact of the body. The present invention is directed to an ultrasonic shoe upper hammering apparatus.

Here, the ultrasonic shoe boot hammering apparatus includes a plate mount fixed to a work table; A universal joint formed at one side of the mount; A slide slot formed by fastening shoe-size swash plates on both sides of the universal joint in the mount; An ultrasonic wave generating housing coupled to the other side of the mount and having a drive unit for the ultrasonic vibrator; An upper bumper fixed support jig having a lower end slidably coupled to the slide slot and having an upper end formed with a shoe bum shape; And the shoe last is inserted into the universal joint so that the shoe last can be rotated forward, backward, and laterally to freely take a posture of the hammering process.

As shown in FIG. 1, the present invention relates to an ultrasonic shoe upper hammering apparatus. The shoe upper hammering apparatus includes an upper 600, an insole (also referred to as a strobel) 620, a shoe last 60, a strobel sewing line 610, The ultrasonic vibrator 40, the plate-shaped mount 100, the universal joint 10 and the swash plate 20, the slide slot 110, the ultrasonic wave generator housing 50, and the upper bumper fixed support jig 30 .

In general, the shoe upper hammering work device is a work device for flattening the rough parts of the concave-convex shape of the upper part of the nose and heel parts and the strobel sewing line part generated during the upper part manufacturing process of shoe making, Is performed to enhance the adhesion between the upper 600 and the insole 620.

The corrugation and strobel sewing line 610 of the upper part of the nose and heel is a part of sewing the upper part 600 of the shoe and the insole (so-called strobel 샥) 620 part, The roughness of the concave-convex shape is generated depending on the work and the curved area form of the upper part 600.

The shoe upper hammering apparatus is constituted by a vibration hammering apparatus which hits an upper part along a rough part of the concavo-convex shape. In the present invention, as shown in Fig. 7, the vibration hammering apparatus has no vibration, And an ultrasonic vibrator (40) free from the impact of the body due to friction.

In the present invention, the ultrasonic vibrator 40 is a rod-shaped housing ultrasonic device capable of moving freely according to a situation and being easily held by a hand due to the shape of a shoe upper having various sizes, different bending state, etc. .

The ultrasonic vibrator 40 of the present invention shown in Fig. 7 is in the form of a bar handle, in which an ultrasonic vibrator for converting ultrasonic energy into mechanical vibration energy is incorporated inside a housing with an operation switch, And a tool horn 400 having a trumpet-shaped hitting portion 410 fastened to the vibrating portion 420 and hitting an object.

The use of the ultrasonic vibrator (40) of the present invention can be used in various fields in which not only the upper part of the shoe but also the corrugated part such as a garment, a bag, a sheet, or the curved surface of the sewing part can be easily made.

The present invention also includes a hammering work support as shown in FIG. 1 to stably perform the shoe upper hammering work with the ultrasonic vibrator 40.

The plate mount 100 is a basic mount of the hammering work support.

A universal joint 10 is formed on one side of the mount 100 and an ultrasonic wave generating housing 50 is formed on the other side.

The universal joint 10 is formed as a stick having a link that freely rotates at all angles like a joystick of a game machine.

The ultrasonic wave generating housing 50 is an ultrasonic wave generating apparatus, and is a case to which the ultrasonic vibrator 40 is connected.

The ultrasonic wave generating housing 50 is connected to an ultrasonic vibrator 40 in the form of a bar-shaped knob, as a terminal output device controlled by the ultrasonic wave power source circuit, in which ultrasonic power source circuits are built in the case.

At this time, it is preferable that the ultrasonic wave generating housing 50 is separated from the plate-shaped mount so that it can be installed separately for convenience of transportation, work process or work process.

The ultrasound generating housing 50 includes a known timer, a toggle switch, an instrument panel, a test button, an output controller, a power switch, and a frequency controller.

The definition of ultrasonic wave generally refers to the vibration of air that a person can hear by sound in a range of 16 to 20,000 Hz, and refers to a vibration of more than 20,000 Hz that can not be heard by a human being as an ultrasonic wave.

Such ultrasonic waves are spreading in various fields such as welding, washing, cleaning, processing, minute, dust collection, and medical treatment.

Among them, Ultrasonic welder, which is used for attaching two synthetic resin products to each other, is designed to weld electric power of 110 ~ 220V, 60HZ (50HZ) to the vibrator through the oscillator This is a device that generates strong momentary force on the joint surface of the complex after conversion to vibrational energy, so that the joint surface of the workpiece is dissolved and bonded to form a strong molecular bond.

At this time, the tool horn 400 of the ultrasonic vibrator 40 is formed in a trumpet shape having a front surface diameter of about 14 to 20 mm.

Generally, in the case of the tool horn 400 of the known rod-handle type ultrasonic vibrator 40, when the diameter is 10 mm or more, the amplitude is decreased and the output is decreased. Therefore, most of the diameter is less than 10 mm.

However, in the method of sewing a shoe upper which is used in the present invention, the work is usually performed with a sewing width of 3 mm on the insole side and a sewing width of 3 mm on the upper side, and is sewn in a zigzag shape with a width of about 6 to 7 mm, When using the tool horn 400, there is a problem that the tool horn 400 is separated from the sewing line during the work due to the minute vibration of the ultrasonic wave during the work, and the work is repeated two or three times.

The ultrasonic vibrator for a shoe upper according to the present invention is characterized in that the diameter of the hitting portion 410 of the tool horn 400 is about 14 to 20 mm so as to prevent the tool horn 400 from leaving the strobing sewing line 610 .

As described above, when the diameter of the striking part 410 of the tool horn 400 is 10 mm or more, the handle housing of the ultrasonic vibrator of the rod handle structure is hardly gripped by hand (about 40% or more) The size and the price of the apparatus are increased, and the shoe upper fabric having a poor heat resistance is damaged.

Therefore, the diameter of the striking part 410 formed at the end of the tool horn 400 is about 14 to 20 mm, and the front surface is flat The trumpet-shaped outer circumference has a thickness as small as 1 to 2 mm as much as possible, and the circumference of the outer circumference is formed with a slope or a curved surface smoothly moving the tool horn 400 in the traveling direction of the work.

In the ultrasonic vibrator 40 of the present invention as described above, since the tool horn 400 has the horn-type striking part 410, the tool horn 400 may be formed in the shape of a trumpet- The rear surface of the striking part 410 of the striking part 410 is reduced by the increased mass of the inclination, so that the same amplitude can be output.

In addition, it is effective that the material of the tool horn 400 of the present invention is made of titanium rather than iron or aluminum in order to prevent breakage or deformation due to trumpet expansion.

In the embodiment of the present invention, when the diameter of the hitting portion 410 of the tool horn 400 is 14 mm, the rear portion of the hitting portion 410 is preferably 10 mm. When the diameter of the hitting portion 410 is 20 mm, It is appropriate to set the rear end of the rear portion 410 to 14 mm.

In addition, the shape of the tool horn 400 may be an ellipse or a rounded square with the same mass.

A swash plate 20 having a length of shoe size is fastened to both sides of the universal joint 10 in the mount 100.

The central portion of the mount 100 becomes a slide slot 110 guided by the side surface of the swash plate 20 by fastening the swash plate 20.

The support base 310 of the upper bumper fixed support jig 30 is provided with a multistage bumper shape classified by the shape of shoes (High, Mid, Low) and size (Men, Woman, Kid, .

In one embodiment, the difference in the last height between the Men size and the Kid size is about 35 to 40 mm, and the difference in the last height between the High shoes and the Low shoes is 40, 50 and 60 mm on average.

In order to use such a variety of deviations in two shapes of two stages as one embodiment of the present invention, the height deviation of the two stages is set to about 10 to 15 mm, and the height of the top surface is set to about 5 degrees Make a slope.

The material to be used is preferably injection-molded using a hard synthetic resin, but a plate material such as wood or synthetic resin may be used by machining a shape with a CNC or MTC machine.

When the worker is working on the bottom portion of the shoe last having the shoe upper, the shoe last 60 is joined to the universal joint 10 as shown in Fig. 2, The jig 30 supports the nose portion of the shoe last 60 so that the shoe last 60 is stably fixed at the time of operation.

The lower end of the upper bumper fixed supporting jig 30 of the present invention is horizontally movable along the slide slot 110 so that the upper bumper fixed supporting jig 30 is moved according to the shape and size of the shoe, The last 60 can be fixed.

Accordingly, as shown in FIGS. 9 to 12, it is possible to select a suitable bumper according to the size of the shoe, so that it is possible to perform a stable operation for any size of shoe.

5 and 6, the swash plate 20 for forming the slide slot 110 is formed by joining the shoe last 60 to the universal joint 10, 60 is laid down, the shoe upper is maintained at a constant angle, thereby improving the convenience of the operation.

For this, the angle of the swash plate is suitably about 10 to 30 degrees.
