The present invention relates to an eyelet coupling device having a sliding mold, and more particularly, by pressing a plurality of eyelets at the top and bottom at the same time in parallel or in parallel to improve the efficiency of eyelet mounting according to the work target, mounting of the eyelet The present invention relates to an eyelet coupling device having a sliding mold configured to enable mass production of a base product requiring eyelets, as well as to adjust a point and to mount eyelets at a predetermined position.

In general, the eyelet coupling device is a hole, such as a tarpaulin, a cloth, a soft material cover, a shopping bag, a tent, a shoe, and then inserts an eyelet into the hole, and presses it as if caulking. It is a coupling device.

The eyelet is hermetically fixed to a drilling hole into which a wire or the like can be inserted, thereby securing an insertion space such as a wire or a string to facilitate fastening and reinforcing the periphery of the drilling hole. Such eyelets form a body portion extending in the height direction of an inner diameter corresponding to the drilling hole, and a circular edge bent vertically from the upper edge of the body portion. In addition, the eyelets may be manufactured in a single unit for each type, or may be configured as a pair of units such as a washer / base.

The conventional riveting device according to the prior art, as disclosed in 2003 registered utility model No. 313858, it is to mount the rivets (hereinafter referred to as 'eyelet') to the base material one at a time.

That is, the prior art device is a sorting passage for sorting and discharging the eyelets, a conveying rail for guiding the discharged eyelets to the engaging position, and presses the eyelets conveyed to the engaging position by such a conveying rail fabric (base material) It consists of upper and lower molds for coupling to the upper surface of the lower mold, the protrusion is inclined downward, the outer peripheral surface of the protrusion is characterized in that the plurality of cutting blades are formed to be inclined downward.

As described above, the prior art eyelets are inefficient at work because one eyelet is mounted at one eyelet mounting position at a time, and in particular, four eyelets or eight eyelets such as a portable shopping bag or a bag are necessary. It is a known fact that the efficiency of mounting (coupling) in the city is very low.

In order to solve this problem, the applicant has disclosed a parallel double-acting eyelet coupling device through 2003 Patent Application No. 3460.

The conventional parallel double-acting eyelet coupling device is to supply the eyelets to the four eyelet mounts in turn with two parts supply, and since the eyelet molds are all fixed, the following problems occur.

In addition, in the case of the fixed eyelet mounting stand, as the impact of punching the press machine is transmitted to the mounting stand as it is, the service life of the mounting stand is relatively shortened and maintenance is inconvenient.

In addition, although the conventional parallel double-acting eyelet coupling device was able to adjust the mounting point of the eyelet, because there is no separate base material guide portion that allows the eyelet to be fitted at a predetermined position based on the base material according to the operator's mistake, even though between the eyelets The problem is that the spacing is constant but the eyelet mounting point is somewhat irregular with respect to the base metal.

Therefore, the present applicant has a lot of research and trial and error on the eyelet combination-related automation device capable of supplying the eyelet to a plurality of locations accurately while having a simpler configuration and easy maintenance. I arrived.

An object of the present invention is to solve the problems as described above, the correct islet mounting as the sliding mold receives the elastic force of the restoring spring in accordance with the vertical reciprocation of the sliding drive shaft arranged in parallel with the press shaft It is possible to provide an eyelet coupling device having a sliding mold capable of increasing operation efficiency by simultaneously combining a plurality of eyelets with a base material at a low noise and quickly.

The worktable 100 is a rectangular frame sized to allow a worker to sit and comfortably perform eyelet mounting work, and the wheels 110 each having a stopper so as to be movable on the bottom of the worktable 100. Combining

The work table 100 is provided with a plurality of guide shafts 130 on the upper plate 120 in the width direction of the table. Each guide shaft 130 is coupled so that both ends thereof are horizontally maintained by the guide shaft rotating support 131.

The work table 100 is provided with a screw shaft 140 in the middle of the guide shaft 130 in the width direction of the table. Here, the screw shaft 140 is also coupled to maintain the horizontal by the screw shaft rotating support 141 so as to rotate both ends thereof.

Each of the guide shaft rotating support 131 and the screw shaft rotating support 141 is fixed perpendicular to the surface of the upper plate 120.

The parallel press unit 200 is arranged perpendicularly to each of the front of the transfer bed (400, 410), the eyelet feeder 300 is erected perpendicular to each of the rear of the transfer bed (400).

Referring to Figure 2, the transfer bed 400 on the right side is to be able to reciprocate each press shaft 711 in the axial direction while the two parallel press unit 200 facing in the vertical direction. At this time, the first actuator 710 is coupled to the upper portion of the pair of mold holder 220, the second actuator 720 is arranged in the lower portion of the mold holder 220. In the same manner, the third and fourth actuators 730 and 740 of the two parallel press units 200 are arranged on the upper and lower portions of the other pair of mold holders 230 in the transfer bed 410 on the left side, respectively. have.

The base material guide part 800 has a plurality of supports 840 for horizontally moving the extension shaft 810. The lower end of each support 840 is fixed upright on both front sides of the worktable 100. In addition, the base support plate 820 is coupled to the upper end of each support 840. The screw shaft fixing lever 830 is attached to the extension shaft coupling hole of the support 840, so that the left and right positions of the base support plate 820 can be adjusted according to the specification of the base material.

The guide shaft 130 coupled to each of the transfer beds 400 and 410 serves to guide the transfer beds 400 and 410 to move horizontally in the width direction of the work table 100.

Here, the screw shaft 140 horizontally moves the transfer beds 400 and 410 in the width direction of the work table 100 by the rotational force thereof, and couples the rotation lever 420 (see FIG. 3) to one end of the shaft. In addition, the screw shaft rotating support 141 rotates together with the rotation of the rotating lever 420 of the operator.

By the way, in the screw shaft 140, the left side portion and the right side portion in the axial direction have threads in the inclined directions opposite to each other. As a result, when the screw shaft 140 rotates in one rotation direction, the transfer beds 400 and 410 are moved close to each other in the center, and when the screw shafts 140 rotate in the other rotation direction, the transfer beds 400 and 410 are separated from each other by the center. do.

According to the operation principle of the transfer bed (400, 410), the parallel press unit 200 and the eyelet feeder (300) arranged on the left and right are transported in close proximity or spaced apart from each other, whereby the eyelet mounting interval of the base material as necessary It can be adjusted.

As shown in FIG. 3, a twisted eyelet chute 310 is disposed between the eyelet feeder 300 and the parallel press part 200 so as to face the eyelet feeding directions opposite to each other while being inclined from a relatively high position to a low position. Are combined.

The plurality of actuators 710, 720, and 760 are respectively coupled to the air supply device 900 through corresponding air flow / exit hoses (not shown).

More specifically, the air supply device 900 is fixed to one side of the work table 100 a plurality of electromagnetic valves 910 for distributing air pressure.

The input port of the electromagnetic valve 910 is connected to the line of the air auxiliary tank 940, the air auxiliary tank 940 is connected to the air supply filter 920 via the pressure gauge 930. Here, the input port of the air supply filter 920 is connected to the external air supply source and the hose receives the pneumatic pressure required for the stroke operation of the actuators (710, 720, 760).

Each output port of the electromagnetic valve 910 is connected to the input and output ports of the corresponding actuators 710, 720, and 760 through hoses.

The control box 600 has a processor, a memory, a relay circuit, and a timer circuit that interlock with a control circuit having an operation algorithm such as a PLC control circuit, and basically opens and closes the electronic valve 910 using an external 110 / 220V power supply. To control.

The control box 600 is electrically connected to receive a control signal from the control panel 500, and has a display panel such as LCD, 7-segments, etc. to output a display signal corresponding to the overall operating state of the apparatus of the present invention. It is connected to the control panel 500.

As shown in FIG. 4, the control box 600 preferably includes a fan 610 for discharging internal air to the outside to prevent the temperature inside the box from rising.

The control box 600 is equipped with a door 620 which can be opened and closed by the hinge 621 and has a transparent glass window, so that the inside of the control box 600 can be visually checked from the outside.

The control panel 500 preferably includes a power switch, a display device, an eyelet mounting counter, an emergency stop button, an operation state indicator, and the like.

The base plate guide surface curved plates 241, 242, and 243 extend to the front side of the work table 100 between the base support plates 820 in the mold holders 230 of the parallel press units 200.

In particular, the first curved plate 241 extends while drawing a flexible curve to the upper part of the worker's knee when the worker is sitting in a chair or the like, the operator simply pushes a plurality of base materials on the knee to the parallel press part 200. It is convenient for quick and accurate eyelet mounting by simply taking it.

In addition, the second curved plate 242 has a shape that is slightly curved upwardly to assist the insertion of the base material.

In addition, since the third curved plate 243 has a triangular side cross-sectional shape while flexing slightly downward in a middle portion between the first curved plate 241 and the second curved plate 242, a base material requiring eyelet work is required. It is responsible for guiding the naturally open upper and lower side ends.

Referring to any one of the parallel press unit 200 shown in FIG. 5 together with FIG. 2, the actuator 710 is a support block of the mold holder 230 by the support pillars 250 at four corners thereof. 231).

The actuator 710 fixes one side of the horizontal adapter 712 to its press shaft 711. The sliding drive shaft 713 is coupled to the other side of the horizontal adapter 712 in parallel with the axial direction of the press shaft 711.

The press shaft 711 and the sliding drive shaft 713 are arranged to penetrate in the thickness direction through the sliding hole formed in the support block 231 of the mold holder 230.

On the other hand, the sliding mold 240 is arranged in the horizontal direction while maintaining a predetermined interval in the height direction between the two mold holder (230).

In order to arrange the sliding mold 240, the mold holder 230 is formed by the hexagonal bolt or the fixing bolt 233 and the fixing member 232 between the supporting blocks 231 located at the top and the bottom of the supporting block. It is fixed to 231.

In addition, a fixing mold 270 having a third curved plate 243 is coupled to the inner center of the mold holder 230 by another fixing bolt 234 in the horizontal direction.

The fixing mold 270 means a conventional eyelet pressing die having a tab hole that opens the lower part of the eyelet when the eyelet is pressed at a position corresponding to the vertical downward direction of the press shaft 711.

In the present invention, two fixed molds 270 are used for the parallel press part 200 on the left side and the right side, and tab holes are formed on the top and bottom surfaces of the respective fixed molds 270.

In addition, a horizontal guide jaw 239 is formed on the inner surface of the mold holder 230, and the horizontal guide jaw 239 is coupled to the sliding slit 245 of the sliding mold 240 as described below, thereby eventually sliding. Sliding movement (forward to backward) of the mold 240 is enabled.

6, the sliding mold 240 has sliding slits 244 and 245 formed on both sides of the rear side thereof, and the sliding slits 244 and 245 have the aforementioned molds. The horizontal guide jaw of the cradle 230 is coupled. In this case, the sliding operation of the sliding mold 240 is limited to the lengths of the sliding slits 244 and 245.

Here, the sliding mold 240 has a driven roller portion 260 arranged in the vertical direction perpendicular to the longitudinal direction of the mold. That is, the driven roller part 260 is fixed to the front side of the sliding mold 240 through the fixing bolt. The roller 261 is coupled to the upper end of the driven roller unit 260 so as to be rotatable by a bolt and a bearing. As the roller 261 contacts the inclined surface 714 of the sliding drive shaft 713, each time the sliding drive shaft 713 reciprocates in the vertical direction, the roller 261 reciprocates the sliding mold 240 by the diameter of one eyelet in the horizontal direction. It is responsible for sliding.

The first groove 246 and the second groove 276 for moving the eyelet are formed on the upper surface of the sliding mold 240 and the upper surface of the inclined feed rail 275, respectively.

Here, the inclined feed rail 275 is installed to receive the eyelet from the twisted eyelet chute 310 using the inclination and gravity in a state seated in the inclined fixing groove of the mold holder 230 mentioned above. . At this time, the lower portion of the inclined transfer rail 275 forms a wedge shape, and thus comes into contact with the upper surface of the sliding mold 240 like an inclined inverse 'T' (see FIG. 4).

As a result, even when the sliding mold 240 reciprocates by the diameter of one eyelet, the inclined feed rail 275 can maintain the inclined state and sequentially transfer the eyelets delivered from the eyelet chute 310. The first groove 246 may be transferred from the groove 276.

In addition, it is preferable that a straight recess 249 is formed so that the eyelet can be smoothly transferred from the second groove 276 of the first groove 246 to the first groove 246.

Meanwhile, the eyelets delivered to the first groove 246 may be temporarily stopped by the stopper spring 247 disposed in front of the first groove 246.

In addition, the sliding restoration spring 280 is coupled to the rear side of the sliding mold 240. Restoration spring 280 is inserted into the spring mounting hole in the horizontal direction of the mold holder 230 as shown in Figure 4, to the fixing jaw 290 is coupled to the rear side of the mold holder 230 Supported by

If the sliding mold 240 moves backward according to the contact relationship between the sliding drive shaft 713 and the driven roller unit 260, the restoring spring 280 generates a restoring force by spring elasticity, and the sliding drive shaft 713 is When it is in the original position, the sliding die 240 is pushed in the forward direction with the restoring force to return to the original position (advanced).

In the following, the operational relationship of the present invention will be described.

First, the power cord of the control box 600 is connected to an external power source, and the power switch of the control panel 500 is turned on.

In this case, the control box 600 controls the electronic valve in accordance with a pre-stored pneumatic algorithm, thereby repeatedly applying the piston shafts of the pneumatic actuators 750 and 760 mounted on the plurality of eyelet feeders 300 during the time when the power is applied. By moving back and forth, the filled eyelets in the box of the eyelet feeder 300 is repeatedly positioned at the top and bottom.

Through this, some eyelets of the eyelet feeder 300 are introduced into the twisted eyelet chute 310 and loaded into the first grooves 246 of the sliding mold 240 along the inclined feed rail 275. The loaded eyelets are temporarily stopped in the first grooves 246 by the stopper spring 247. The foremost eyelet in direct contact with the stopper spring 247 is located at a position coinciding with the axial direction of the press shaft 711.

The worker grasps the base material to which the eyelet is to be mounted by hand and inserts it into the gap between the sliding mold 240 and the fixed mold 270 using the curved base plates 241, 242, and 243 for the base material guide.

At this time, as the side edge of the base material is restrained by the base material support plate 820 of the base material guide part 800, the eyelet mounting point is very easily coincided with the preset position.

In this state, when the operator presses a push switch (not shown) for actuator operation electrically connected to the control box 600, the control circuit of the control box 600 receiving such a switch press signal controls the electronic valve, The first to fourth actuators 710 to 740 are operated simultaneously.

That is, the press shafts 711 of the first to fourth actuators 710 to 740 and the sliding drive shaft 713 coupled to the horizontal adapter 712 simultaneously reciprocate a predetermined stroke distance.

At this time, the sliding drive shaft 713 is in inclined contact with the driven roller unit 260 to advance the sliding mold 240 by the diameter of one eyelet.

Restoration spring 280 is pressed along the reverse of the sliding mold 240 has a restoring force.

By the way, the eyelets loaded in the first groove 246 of the sliding mold 240 are the first weight of the sliding mold 240 by the weight of the other eyelets in the eyelet chute 310 and the inclined transfer rail 275. The groove 246 maintains the stop state as it is.

Thus, the foremost eyelet is positioned in the air for a very short time, and at the same time, the end of each press shaft 711 is sewn into the hole of the eyelet located in the air and downwardly into the tap hole of each fixing mold 270. Move.

The lower portion of each moving eyelet is in contact with the tab hole of the fixing mold 270 while punching the base material. Thereafter, the lower part of the eyelet is radially opened in the tab hole of the fixing mold 270 by the pressing force of the press shaft 711, and thus is coupled to the base material.

Thereafter, the control box 600 controls the electromagnetic valve to allow the first to fourth actuators 710 to 740 to return the respective press shafts 711 and the sliding drive shafts 713 to their original positions, and then press the next switch. Maintain standby state until signal input.

In this case, the restoring spring 280 advances the sliding mold 240, and a space equal to the diameter of one eyelet is created in the first groove 246 of the sliding mold 240 which is thus advanced.

As a result, other eyelets in the eyelet chute 310 and the inclined conveying rail 275 transfer the eyelets of the first groove 246 of the sliding mold 240 to the position where the stopper spring 247 is located by the weight thereof. .

Through this process, four eyelets can be simultaneously bonded to the base material.

As described in detail above, since the eyelet coupling device having the sliding mold of the present invention can couple a plurality of eyelets to the base material at the same time, there is an effect of relatively maximizing the coupling work efficiency.

In addition, since the eyelet coupling device having the sliding mold of the present invention does not directly contact the sliding shaft with the press shaft, there is almost no breakage or residual failure of the sliding mold, and thus easy maintenance and increase the life of the sliding mold. There is an advantage.                     

In addition, the eyelet coupling device having the sliding mold of the present invention is very economical because it is possible to mass-produce high quality products having the correct coupling position by combining four eyelets at the same time at the same time with only one manual operation.

In addition, the eyelet coupling device having a sliding mold of the present invention provides a plurality of transfer beds coupled to the screw shaft, can easily adjust the spacing between the eyelets, can be easily extended from two to many as in the description of the present invention That has excellent scalability.

In addition, the eyelet coupling device having a sliding mold of the present invention has an advantage that it is very easy to work with the position of the eyelet to hold the center of the base material or to bind to the base material by providing a base material guide portion.                     

In the above description, the technical idea of the eyelet coupling device having the sliding mold of the present invention has been described with the accompanying drawings, but this is by way of example and not by way of limitation. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
