Description

Technical Field [0001] The present invention relates to a cap attachment system with an adjustable wet tissue case,

The present invention relates to a wet tissue cap attaching system, and more particularly, to a wet tissue cap attaching system in which a wet tissue cap and a wet tissue case are moved in directions perpendicular to each other, The present invention relates to a wet tissue cap attaching system for an adjustable wet tissue case, which can improve product productivity.

Generally, a wet tissue is made of synthetic fibers or natural fibers, water is added and sterilized, and a plurality of wet tissues are packaged in a wet tissue case made of a flexible material. The wet tissue case has an outlet for taking out the wet tissue, and a wet tissue cap capable of opening and closing is provided at the outlet. The wet tissue cap is attached to the wet tissue case through an adhesive to prevent natural moisture evaporation of the wet tissue being exposed to the outlet during use. On the other hand, in the process of manually or semi-manually attaching the wet tissue cap to the wet tissue case, an automatic and continuous attachment device is required because labor is required and productivity is low.

As a background of the present invention, Korean Patent Registration No. 10-1598272 has proposed a cap attaching device for a wet tissue case. A first conveyor belt in which a wet tissue case to which a cap is to be attached is continuously supplied to the upper surface; A second conveyor belt disposed parallel to the first conveyor belt for continuously feeding the cap to be attached to the upper surface of the wet tissue case fed by the first conveyor belt; A cap supply end disposed on the upstream side of the second conveyor belt for supplying the cap to the second conveyor belt; A labeling end disposed downstream of the cap feed end on the second conveyor belt for attaching a label to an upper surface of the cap; A wet tissue case alignment state detector disposed on the first conveyor belt downstream of the labeling stage for detecting an alignment state of the wet tissue case supplied by the first conveyor belt; A hot melt application end disposed on the downstream side of the first conveyor belt and the second conveyor belt for applying hot melt to the bottom surface of the cap; And a cap attached to the upper surface of the wet tissue case, which is supplied by the first conveyor belt, after the cap is picked up so that the hot melt can be applied to the bottom surface of the cap, And the like.

  The above-described background art has an advantage that the cap can be automatically and continuously attached to the wet tissue case. However, since the first conveyor belt for feeding the wet tissue case and the second conveyor belt for supplying the cap are arranged in parallel, The cap supply is performed by driving the pneumatic cylinder in the forward and backward movement, which limits the cap supply speed. Therefore, there is a problem that the productivity of the product is low. Further, only two feed cylinders for feeding the caps can be provided, which makes it difficult to supply a large amount of feed. Further, since the position of the injection nozzle is fixed, there is a problem that it can not be moved according to the size of the product.

4 and 5, the wet tissue cap feeding unit 20 includes a cap discharger 21 having a cap discharging port 21a penetrating in the thickness direction at a position having a certain radius R from the center of the circle, And a plurality of cap supply openings 22a disposed on the upper side of the publication 21 and rotatably installed and having the same size and the same radius R as those of the cap discharge ports 21a and arranged at regular intervals in the circumferential direction A cap feeding rotary table 22 and four cap stacking guides 22 arranged vertically above the respective cap supply ports 22a and arranged at rectangular corners so as to vertically stack a large number of wet tissue caps 2 A bar 23 and a cap 4 for guiding the wet tissue cap 2 having been vertically downwardly disposed on the cap outlet 21a side and arranged at a rectangular corner and passing through the cap outlet 21a to the wet tissue cap conveying conveyor 30 A guide bar 24 for cap insertion, A cap supplying shutter 25 disposed between the plate 21 and the cap supplying rotary table 22 for opening and closing the cap discharging port 21a; A shutter cylinder 26 for causing the shutter 25 to move forward and backward from the cap outlet 21a and a cap supply / rotation table 22 provided on the cap discharge plate 21 side for rotating the cap supply rotary table 22, And a rotary table drive motor 27 for matching the sphere 22a to the cap discharge port 21a side.

The four guide bars for cap stacking 23 and the guide bars for cap insertion 24 are provided with a guide bar width adjusting plate having a long hole 29a for adjusting the width according to the size of the wet tissue cap 2 29) are connected to each other through a bolt. One pair of the four guide bars 23 for cap stacking is connected to the support block 225 supported on the cap feed rotary table 22 side through bolt connection and the other pair is connected to the guide bar width adjustment plate 29). Further, one of the four guide bars 24 for capping is connected through the same support block supported on the cap press plate 21 side, and the other pair is connected through the same guide bar width adjustment plate.

In addition, a cross-shaped sensing dog 272 is provided on the rotation axis of the rotary table drive motor 27 to rotate the cap-supplying rotary table 22 by 90 degrees.

Therefore, in the state where the cap outlet 21a and the cap supply port 22a are aligned with each other and the cap supply shutter 25 covers the cap outlet 21a, The dropping movement of the wet tissue cap 2 is stopped by the cap supplying shutter 25 and the supply to the wet tissue cap transporting conveyor 30 is stopped.

In this state, when the shutter cylinder 26 advances and the cap outlet 21a is opened, the wipes caps 2 stacked on the guide bar 23 for stacking the caps pass through the cap outlet 21a, And guided by the guide bar 24 for the downward movement, thereby being stacked on top of the wet tissue transfer conveyor 30. Thereafter, the shutter cylinder 26 is retracted to close the cap outlet 21a. Accordingly, the wipes cap 2 is placed one by one on the wet tissue transfer conveyor 30 in accordance with the intermittent movement of the wet tissue cap transfer conveyor 30.

When all the wet tissue caps 2 stacked on one portion of the cap feeding rotary table 22 are supplied, an unillustrated sensing sensor senses the rotation, so that the rotary table drive motor 27 is driven to rotate 90 degrees So that the wiped tissue cap 2 stacked on the cap stacking guide bar 23 at the next neighboring position is positioned at a position to be fed. At this time, the position of the cruciform sensing dog 272 installed on the rotation axis of the rotary table drive motor 27 is sensed by a sensor not shown, and rotation division by 90 degrees is performed.

The wet tissue cap transfer conveyor 30 serves to transfer the wet tissue cap 2 supplied from the wet tissue cap supply unit 20 repeatedly from one side to the other side for a predetermined period of time. The wet tissue cap transfer conveyor 30 has a transfer chain 33 connected to the drive sprocket 31 and the driven sprocket 32 as shown in Figs. 1 and 7, and the transfer chain 33 is provided with a wet tissue cap support And a cross-shaped sensing dog 36 is installed on the rotary shaft of the chain conveying motor 35 for rotationally driving the driving sprocket 31 so as to intermittently rotate as shown in FIG.

Therefore, the intermittent rotation drive of the chain feed motor 35 causes the conveying chain 33 to perform a long track type rotational movement, whereby the conveyance chain 33 is linearly moved from the upper part, 34 are guided by the transfer chain 33 to transfer the wet tissue cap 2 to the discharge end side. Here, the discharge end means the portion where the wet tissue cap 2 is positioned at the final stage by the transfer chain 33 and the adhesive spray unit 40 is provided.

8A and 8B, the adhesive injection unit 40 is disposed at one side of the discharge end of the wet tissue cap transfer unit 20. [ The adhesive injection unit 40 serves to spray an adhesive onto the bottom surface of the wet tissue cap 2. [

The adhesive injection unit 40 includes a pair of nozzle support plates 41 provided on one side of the discharge end of the wet tissue transfer conveyor 30 for facilitating the position change of the injection, A pair of nozzle connecting clamps 43 clamped by a pair of tightening bolts 45 to be moved and fixed to the nozzle supporting shaft 42, And a jetting block 44 mounted on the connecting clamp 43 side and having a jetting nozzle 441.

The pair of nozzle connecting clamps 43 are formed with gripping grooves 43a for holding the nozzle support shaft 42 on the surfaces facing each other and the pair of tightening bolts 45 are provided with gripping grooves 43a Respectively. Accordingly, when the pair of fastening bolts 45 are tightened, the gap between the pair of nozzle connecting clamps 43 is narrowed, and the grip groove 43a strongly contacts the nozzle support shaft 42 to fix the position. Further, when the pair of tightening bolts 45 are loosened, the pair of nozzle connecting clamps 43 move along the nozzle supporting shaft 42, and the position can be adjusted. In this manner, the position of the injection nozzle 441 in the adhesive injection unit 40 is adjustable so that the setting of the injection position can be facilitated. On the other hand, as shown in FIG. 8C, it is preferable to provide an adhesive tray 47 for receiving an adhesive scattering downward when jetting the adhesive onto the jetting nozzle 441 side. When the adhesive tray 47 is provided, a part of the adhesive is recovered, thereby reducing unnecessary waste and avoiding contamination of the surroundings.

In the present embodiment, the multi-joint cap attaching robot 60 has a triaxial joint structure, but is not limited to this structure.

The process of attaching the wet tissue cap in the wet tissue cap attaching system of the wet tissue case constructed as above will be described.

First, when the shutter cylinder 26 performs a single reciprocating operation in a state in which the cap outlet 21a and the cap inlet 22a are aligned with each other in the wet tissue cap supply unit 20, And the cap outlet 21a is opened and closed. At this time, one of the wet tissue caps 2 stacked on the cap stacking guide bar 23 is passed through the opened cap outlet 21a, And is fed to the conveying conveyor 30. In this process, the wipes cap 2 exiting the cap outlet 21a is guided by the cap guide guide bar 24 and is positioned as the wet tissue cap transfer conveyor 30.

In this process, the intermittent rotation of the chain conveying motor 35 causes the conveying chain 33 to perform a long track-type rotation, whereby the conveying chain 33 is linearly moved at the upper portion, Is guided by the transfer chain (33) to transfer the wet tissue cap (2) to the discharge end side. Here, the label is attached to the upper surface of the wet tissue cap 2 by the label attaching unit 90 during the transfer of the wet tissue cap 2.

When the wet tissue cap 2 reaches the discharge end side, the joint cap attaching robot 60, which senses the position of the wet tissue cap 2, moves the wet tissue cap 2 reaching the discharge end side of the wet tissue transfer conveyor 30 to the suction port After the adsorption in one step, the adhesive is injected onto the bottom surface of the wet tissue cap 2 in a two-step manner by swinging in a direction above the spraying direction of the adhesive sprayed from the spray nozzle 441, The wet tissue cap 2 is finally attached to the wet tissue case 3.

As described above, according to the present invention, the wet tissue cap supply unit 20 stacks the wet tissue caps 2 vertically on the rotation table 22 for cap supply, and at the same time, And the production efficiency of the wet tissue product is increased. Further, the injection nozzle 441 included in the adhesive injection unit 40 is configured to be movable in position on the nozzle support shaft 42, so that the setting position can be easily changed. Since the wet tissue cap transfer conveyor 30 and the wet tissue case transfer conveyor 50 are installed in directions perpendicular to each other, the multi-joint cap attaching robot 60 applies the adhesive to the wet tissue cap 2, It can be attached to the wet tissue case 3 with a distance as shown in FIG. 10, thereby increasing the speed of attaching the cap.

On the other hand, in the present invention, two wet tissue caps 2 may be adsorbed to increase the production speed of the product.
