Description

Eyelet bonding press device and eyelet

The present invention relates to an eyelet bonding press apparatus and eyelet, and in particular, the eyelet coupled to the fabric allows work to be performed in one die, thereby improving work efficiency and also preventing the eyelet from being separated when the fabric is folded. The present invention relates to an eyelet bonding press device and an eyelet, which prevents the hand from being injured and, together with this, eliminates the labor and contamination caused by separation when the cloth is disposed of.

In general, eyelets are used to cover things with tarpaulins in warehouses, docks, parking lots, beaches, cruises, etc., or install them in tents, vehicle covers, etc., and are generally used to easily bind tents or covers with wires.

Brief description of the technique of the die used in the conventional press machine in Utility Model Publication No. 94-2209 is as follows.

First, a table is formed on the front of the main body of the press, and a die used for drilling holes in the cloth and a die used for bonding eyelets to the cloth are respectively provided, and one side of the die moves left and right. In order to receive the power from the main body to receive the rod is installed.

And the upper part of the die is punched with punch punch and eyelet are combined while slidingly coupled to each other, the punch and press is installed to operate up and down by receiving power from the main body of the press.

Referring to the operation of the conventional technology configured as described above is as follows.

Placing the cloth on the die first and operating the press machine will punch the cloth as the punch descends.

When the fabric is perforated as described above, the base constituting the eyelet is positioned on the upper surface of the fabric, and the washer is positioned inside the die.

When the press is continuously operated, the rod is advanced by the power transmitted from the main body, and at the same time, the die for drilling the eyelet is pushed to one side by the rod, and the die for coupling the eyelets is positioned under the press.

When the press is operated in the state where the die is adjusted as described above, the punch and the press descend together to press the upper part of the base, whereby the base is coupled to the washer while passing through the hole of the cloth. The eyelet is fixed to the fabric.

The eyelets installed as described above are provided with a plurality of eyelets at predetermined intervals depending on the use of the cloth.

The prior art described above has a structure in which a pair of dies are flowed left and right, and the eyelets are coupled to the cloth, thereby degrading work efficiency due to a complicated structure.

Another problem is that as the die flows to the left and right, the eyelet is bonded to the fabric, so that the binding state of the eyelet becomes unstable and is easily separated from the cloth.

On the other hand, when looking at the conventional eyelet structure in Published Utility Model Publication No. 95-14715.

First, the eyelet is composed of a metal flange and a cap. The upper surface of the flange is formed with an uneven groove and an uneven protrusion, and a central portion of the bush is integrally formed vertically, and a through hole is formed in the central portion of the bushing.

And the lower surface of the cap is formed with another uneven groove formed in the flange and the uneven protrusions and the uneven projections, the central portion of the cam is formed with a through-hole communicating with the through holes formed in the flange.

Along with the through hole central portion of the cap is formed a locking groove to be caught by the locking step formed in the bushing.

A description will be given of the conventional technique configured as described above in connection with the following.

When the bushing of the flange is coupled to the perforated tent, the uneven groove and the uneven protrusion formed on the upper surface of the flange are in close contact with the back of the cloth.

When the cap is coupled to the bushing while the coupling operation is performed as described above, the bushing is coupled to the through hole of the cap and the locking jaw is caught in the locking groove, and at the same time, the uneven groove and the uneven protrusion formed on the bottom of the cap It is in close contact with the upper surface.

The prior art described above has a structure in which the catching jaw of the bushing is caught by the catching groove of the cap. When the external force is repeatedly applied in the process of using the cloth for a long time, the catching jaw is easily separated from the catching groove. Often a problem arises that separates from.

Another problem is that when the folded fabric is folded, the eyelet is often positioned vertically, and when the cloth is forcibly folded while being folded, the fabric is damaged or the hand of the worker is injured.

Another problem is that since the eyelets are made of metal, when the disposable ends of the cloth are discarded without being separated from the cloth, it becomes a major factor of environmental pollution, as well as the cumbersome work if you want to separate them. This is raised.

It is an object of the present invention to simplify the structure of the die, thereby making it easier for the operator to work on the table.

Another purpose is to realize a structure in which the eyelet can be firmly bonded to the fabric, so that the eyelet and the cloth can be continuously bonded even if the external force is repeatedly exerted, and the eyelet contains a large amount of polycarbonate. It is made of materials to eliminate the labor and contamination of separation when disposing of the cloth.

Another purpose is to prevent the fabric from being damaged or injured by the eyelet when it is folded to store the unfolded fabric.

The pressure 98 formed in the washer 44 is located inside the prong 106 formed in the base 42.

The operation of the present invention configured as described above will be described in detail with reference to FIGS. 8A to 8H.

First, when a worker places a cloth 30 for coupling the eyelet 36 on the die 38 on the table 80 of the die 38 and turns on a power switch not shown, FIG. 8. As shown in (a) of the solenoid b (74) received the command from the control unit 6 while operating the bar (72) to retreat from the hole 90 formed in the rack (88).

In this case, the commands provided from the control unit 6 operate in the order as shown in FIGS. 8A to 8G.

At the same time, the drive motor b 76 receives the operation command from the control unit 6 and rotates the pinion 78. As a result, the rack 88, which is geared to the pinion 78, is engaged with the bar 86. The table 80 and the like are raised.

When the table 80 rises out of the rest room 62 as described above, the rack 88 and the bar 86 are raised while slidingly moving along the guide ball 68.

At this time, when the stopper pin 92 installed on the rack 88 rises and contacts the bottom surface of the body 54, further rising stops, and at the same time, the driving motor 76 is operated for the time set in the control unit 6. Operation is turned off.

In addition, the control unit 6 transmits an off command to the solenoid b 74 so that the backward bar 72 moves forward. Thus, the tip of the bar 72 has a hole 90 formed in the rack 88. ) Is inserted.

Therefore, the bar 72 is supported to prevent the raised table 80 from descending.

As described above, the table 80 which is lifted out of the rest room 62 is positioned on a line coinciding with the upper end of the guide wall 56.

When the operation is completed as described above is placed on the table 80, the fabric 30 to which the eyelet 36 is to be coupled.

Subsequently, the driving motor a8 installed in the press 2 operates to transmit power through the belt 10 to rotate the wheels a and b 12 and 16 together with the cams a and b 14 and 18. Due to this, the rear end of the lever 20 located between the cams a and b (14, 18) is rotated about the hinge pin 22 to transmit power.

The power transmitted in the unlocked state of the rocker 28 thus causes the press 26 to remain intact and only the punch 24 is lowered as shown in FIG. 8B.

When the punch 24 is lowered as described above, the rake 32 provided at the lower end is separated from the groove 34 formed at the lower end of the press 26, and at the same time, the lower end of the punch 24 is the table 80. It will pass through the cloth (30) located on the top.

In this case, the punch 24 penetrates a part of the cloth 30, and at the same time, the rake 32 partially cuts the edge of the perforated hole, thereby allowing the base 42 to be easily coupled. .

Subsequently, the punch 24 descends and passes through the hole b 82 of the table 80 and the hole a 64 of the body 54, and the part of the fabric 30 cut out from the cloth 30 is the body ( Out through the hole a (64) of 54).

When the operation is completed as described above, the lowered punch 24 is returned to its original position as shown in FIG. 8C by the transmitted power.

When the punch 24 returns to the original position as described above, the control unit 6 transmits a command to the solenoid b 74 to retract the bar 72 again, thereby freeing the movement of the rack 88. The pinion 78 is rotated in the reverse direction by maintaining a command and simultaneously transmitting a command to the driving motor b 76.

Accordingly, the rack 88 geared to the pinion 78 descends together with the bar 86 and the table 80 and returns to the rest room 62, which is its original position.

At this time, the upper surface of the table 80 is lowered by a predetermined distance from the upper surface of the body 54.

When the operation is terminated as described above, the washer 44 is discharged from the box a 50 causing the vibration, descending through the chute a 46 and then along the guide wall 56 of the body 54 in FIG. 8d. As shown, it reaches the table 80.

When the washer 44 arrives as described above, the control unit 6 transmits a command to the solenoid a 60 to rotate the arm 58 as shown in FIG. 8E so that the tip of the arm 58 is rotated. One end of the washer 44 is pressed to fix it.

When the operation is completed as described above, as shown in FIG. 8F, the base 42 moves away from the box b 52 causing the vibration, and moves along the chute b 48 to move the cloth positioned above the table 80. The upper part of 30 is reached.

When the locker 28 is locked after the movement of the base 42 and the washer 44 is completed as described above, as shown in FIG. 8G, the punch 24 and the press 26 are lowered together, and the base is lowered. The upper part of 42 is pressed.

Therefore, the boss 102 of the base 42 passes through the hole of the cloth 30 perforated by the external force transmitted, and at this time, the edge of the hole is easily coupled due to the cut portion.

Subsequently, the base 42 descends to reach the upper surface of the table 80, and at the same time, the boss 102 of the base 42 opens while the lower end is opened outward by the pressing force of the press 26. It enters the bottom of (44).

As a result, the washer 44 is raised inside the rest room 62 by the lower end of the boss 102 entering the bottom, and is in close contact with the bottom of the cloth 30 as shown in FIG. 8H, and at the same time the washer ( The pressure 98 formed on the upper surface of the 44 is pressed and fixed while pushing a portion of the cloth 30 into the groove 104 formed in the base 100.

In addition, the bottom surface of the base 42 pressed by the press 26 is in close contact with the upper surface of the cloth 30, which causes the prongs 106 to penetrate the cloth 30.

Accordingly, the prongs 106 of the base 42 and the pressureors 98 of the washers 44 are in a state of fixing the eyelets 36 so as not to flow from the cloth 30 as a whole.

When the work is completed as described above, the lowered press 26 and the punch 24 are returned to their original positions by the power provided from the driving motor a 8 to repeatedly perform the same operation.

The present invention has an effect that the work efficiency is further improved by having a structure in which the eyelet can be coupled to the cloth in one die installed on the table.

Another effect is that the eyelet has a structure that can be firmly bonded to the fabric, so that the eyelet can be firmly coupled even if the external force continuously acts on the cloth and the eyelet, and also by separating the eyelet from the polycarbonate material. This can eliminate the labor and pollution.

Another effect is that when folded to store the fabric, it is possible to prevent the fabric from being damaged by the edge of the eyelet or the hand of the worker.
