Description

Apparatus for welding open end of sponge gourd}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrubber, and more particularly, to a scrubber-sealing-joining apparatus suitable for welding both ends in a scrubber manufactured by accommodating a sponge in a tubular woven polyester sheath and then ultrasonically welding both ends thereof. will be.

The loofah mainly used in the kitchen has been conventionally used for nonwoven fabric, sponge, cotton cloth, etc., but in order to improve the function of the above structure of the two materials bonded together, or a composite yarn mixed with a ribbon yarn or a synthetic yarn in a metal yarn It has been developed into a structure in which a sponge is housed inside a woven tube-like shell and both ends are ultrasonically welded integrally.

In terms of functionality, scrubbers made of cotton cloth or sponge only have excellent ability to absorb moisture, but are easily worn and washed, whereas non-woven scrubbers have excellent cleaning effect but low moisture absorption ability. However, a scrubber of a structure in which a sponge is stored therein is widely used because it sufficiently compensates for the above disadvantages.

A scrubber of a structure in which a sponge is stored inside and ultrasonically welded to both ends of the seal is known from Korean Patent No. 95-8362. The scrubber disclosed herein has a structure in which a polyester ribbon yarn and a polyester yarn are rounded to produce a tube-like shell, a sponge is inserted into the shell, and the ultrasonic tool horn is pressed to join the outer shell. In the disclosed scrubber manufacturing method, no mechanical means of supplying a sponge containing a sponge therein is presented. This example is known in the art as described in US Pat. No. 5,441,333, which simultaneously produces a method of producing multiple scrubbers by simultaneously compressing and cutting a mechanically conveyed skin into a plurality of ultrasonic tool horns. There is a need for an installation space, and a worker has to load a material in which a sponge is stored inside the shell. In addition, since the scrubber of the above configuration is only pressed by the ultrasonic tool horn in the bonding step, as shown in FIG. 6, the edge portions 3, 4, 5, 6 of the outer shell 2 joined together with the sponge 1 inside. ) Has a gap (7a) that is not the pressure of the ultrasonic tool horn, the gap (7a) is easily broken during use and acts as a factor of shortening the life.

The present inventor has proposed the Republic of Korea Patent Application No. 96-1259 for the purpose of solving the above problems. The applied loofah is bonded to both ends of the edge (3, 4, 5, 6) as shown in Figure 7 folded in such that there is no gap. However, the loofah of the improved structure is also manufactured by supplying a certain length of material to the ultrasonic tool horn, and then manipulating the pedal, etc., so that the finger is advanced at the side of the material by the operation of the link mechanism to press the outer shell to be folded inward. This method is extremely productive because it relies almost on manual.

Accordingly, an object of the present invention is to provide a scrubber sealing joint joining device capable of automatically producing a scrubber having a structure in which both end corners are folded in and arranged in a narrow space, thereby increasing productivity.

In the present invention for realizing the above object, in the scrubber sealing portion joining device in which the ultrasonic tool horn is disposed on one side of the base, ultrasonic welding and cutting the material made of the outer skin in which the sponge is accommodated, In the manufacturing apparatus, the chute disposed on the upper side of the base to guide the scrubbing material, and the capture provided on the upper side of the frame in cooperation with the lower non-slip to secure the material supplied in the chute, the second cylinder is said A carrier for moving the material intermittently by a predetermined length by moving the frame, and a general ultrasonic tool horn are installed in a center so as to be lifted and lowered to a position corresponding to both sides of the material supplied to the lower side of the ultrasonic tool horn. These two fork-shaped plungers are disposed opposite each other to face the side of the supplied material. It is equipped with a push portion which is welded into donor composed.

In the apparatus of the present invention as described above, the capture may be configured to be lifted and operated by the first cylinder and the frame by the second cylinder.

In addition, it may be carried out in a configuration in which a fixed capture is further provided on the inlet side and the outlet side of the weld portion, respectively, which is interlocked with the third cylinder.

In addition, a cutting knife protruding downwardly is built into the inside of the ultrasonic tool horn, and both sides thereof are connected to a rod supported on the side of the ultrasonic tool horn via a spring spring, and the upper end of the rod is fixed by a trigger. It is formed as a hook to be supported by the hook, the middle of the piston rod connected to the ultrasonic tool horn may be added to the corresponding installation of the push rod for interlocking the trigger.

The device of the present invention having such a configuration is that all operations required for joining the scrubber are automatically performed by simply supplying the material to the chute, so that the desired shape, i.e., no gap between the two, can be obtained while saving the manpower. It can produce scrubbers bonded by structure and can be installed even in narrow spaces.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the structure of the apparatus according to the present invention, the upper side of the base 2 is provided with a chute (4) for guiding and correctly feeding the scrubber material (S) made of a sheath containing the sponge, A carrier 6 for intermittently transporting the raw material S is arranged in succession to the chute 4, and a welding portion 8 is provided at a predetermined distance from the carrier 6.

On the path of the chute 4, a pair of guiders 42 which are in contact with both side edges of the material S and guide the same are arranged to face each other, and on the other hand, the presence of the material S is present. The sensor 44 for detecting the is provided.

The carrier 6 is composed of a frame 60 for intermittently transporting the material S supplied through the chute 4, and a first cylinder 62 is provided on the upper side of the frame 60, so that the carrier 6 The capture 64 of the structure is configured to be lifted and operated, and the non-slip 66 is fixedly arranged on the lower side opposite to the capture 64. The frame 60 of this structure is the chute 4; The second cylinder 68 attached to the lower side of the intermittently reciprocates the predetermined distance.

That is, as shown in FIG. 2, when the upper capture 64 piggybacks on the lowering operation of the first cylinder 62 and presses and fixes the material S between the non-slip 66, the second cylinder is next. 68 is operated to move the frame 60 forward, and at the moved position, the first cylinder 62 is lifted up again to release the material S to be intermittently fed and supplied by a predetermined length. At this time, the sensor 44 detects the absence of the material S on the chute 4 and informs the worker through an alarm signal.

The welding portion 8 holds the ultrasonic tool horn 84 extending from the conventional ultrasonic oscillator 82, and the ultrasonic tool horn 84 is lifted and operated by the lifting cylinder 86 at regular intervals. On the inlet side and the outlet side of the welded portion 8, a fixed capture 90 which moves up and down in conjunction with the third cylinder 88 is provided to temporarily fix the material S loaded into the welded portion 8. . On the other hand, the sensor 92 is provided also around the entrance of the welding part 8, and the supply mode of the raw material S is checked. In other words, the sensor 92 detects that the middle part is bent on a part of the apparatus while the material S is being supplied, and emits an alarm signal.

3 is a perspective view showing a detailed configuration related to the welding portion 8, wherein a cutting knife 94 is built in the lower inner side of the ultrasonic tool horn 84, and on both sides of the ultrasonic tool horn 84, respectively. A plunger 96 with a two-fork tip is depicted depicting a configuration in which the plunger 96 is separately arranged to be retractable by the fourth cylinder 98.

Both sides of the cutting knife 94 is supported by the side of the ultrasonic tool horn 84 to be elevated and connected to the rod 102 is installed on the outer circumference spring 100, while the upper end of the rod 102 is triggered It is formed by the hook 106 so that it may be caught by 104. As shown in FIG.

In addition, a push rod 110 for interfering with the trigger 104 is extended in the middle of the piston rod 108 connected to the center of the ultrasonic tool horn 84.

In addition, a support 114 is provided at an appropriate position of the base 2 with respect to the ultrasonic tool horn 84 that is lowered. Therefore, the ultrasonic tool horn 84 faces the support 114 with the material S in the bottom dead center. The support 114 has a gap 116 therein through which the cutting knife 94 installed in the ultrasonic tool horn 84 can enter.

Unlike the ultrasonic tool horn 84 in which the both triggers 104 are fixed to the appropriate portions inside the support 112 that supports the ultrasonic oscillator 82 and move up and down as shown in FIG. 1. It is fixed at a certain position. Accordingly, when the push rod 110 is lowered to a predetermined position along with the downward movement of the ultrasonic tool horn 84, the hook 106 is released as shown in FIG. 4. In addition, when the hook 106 is released, the energy stored in the carbon spring 100 is actuated and the cutting knife 94 protrudes to the lower side of the ultrasonic tool horn 94 to cut the material S. At this time, the plunger 96 is pressed into the side by pressing the side surface of the raw material S by the operation of the fourth cylinder 98.

The fourth cylinder 98 is operated forward before the ultrasonic tool horn 84 is lowered so that both sides of the material S are folded inward by the plunger 96, and this operating state is the ultrasonic tool horn ( 84) is lowered to continue until the material (S) to join and cut.

FIG. 5 shows the operation of the cutting knife 94 in conjunction with the lifting operation of the ultrasonic tool horn 84. When the ultrasonic tool horn 84 starts to descend, the rods 102 on both sides thereof have hooks of the upper end ( As the 106 is caught by the trigger 104, it becomes a floating phase and stops to a certain height. Therefore, even if the lowering of the ultrasonic tool horn 84 continues, the tantalizing spring 100 is folded, and thus the rod 102 does not interlock, and thus the cutting knife 94 is stopped as it is. On the other hand, since the ultrasonic tool horn 84 is lowered by the extension movement of the piston rod 108, the push rod 110 is also lowered to approach the trigger 104. If the lowering of the ultrasonic tool horn 84 continues, the push rod 110 contacts the trigger 104 at a certain time and descends while pressing it downward. When the trigger 104 is pushed by the push rod 110, the trigger 104 releases the shank 106, and at the same time, energy stored in the bullet spring 100 is extracted and the cutting knife 94 is ultrasonic tool horn ( 84 is moved and projected downward from the inside, as a result of which the cutting of the material (S) is performed.

The cutting action as described above is performed after the material S is pressed by the ultrasonic tool horn 84, so that the cutting operation is performed neatly and uniformly.

As described above, when the cutting of the material S is ended, the ultrasonic tool horn 84 starts to move up again. In this case, the rod 102 rises together and the push rod 110 moves at the trigger 104. And the trigger 104 is restored to its original posture by the action of a left-hand spring (not shown but generally applied with a torsion spring), and then re-locks when the hook 106 is moved up to its position. do.

In the device of the present invention, the first to fourth cylinders 62, 68, 88, 98 and the lifting cylinder 86 must be sequence controlled to be able to operate in cycles. Such a sequence control adopts a general controller that receives and calculates an output of an electronic signal using a limit switch, and outputs a control signal, or equalizes the velocity of the fluid supplied to each cylinder and pilots the fluid supplied to each cylinder. When dispensing via the valve, since the dispensing timing is set differently according to the stroke and the capacity of each cylinder, the detailed description thereof will be omitted.

The scrubber bonded through the apparatus of the present invention as described above is manufactured in a bonded structure with both edges 3, 4, 5, 6 folded inward as shown in FIG.

As described above, the apparatus of the present invention can produce a scrubber bonded in a desired form while saving the manpower because all operations required for splicing the scrubber are automatically performed just by supplying the material to the chute. have.
