Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wet towel winding and packaging machine that rolls up a wet small hand towel into a rod shape and places it in a plastic film bag for sealing packaging.

(Conventional technology) A conventional wet towel winding and packaging machine rolls up the towels one by one into a rod shape at the top roll-up section, and then attaches the towels to the side seal section, which glues the left and right ends of the middle plastic film, and the upper and lower ends of the film. With the upper and lower seal cut sections that glue both ends to form a bag and simultaneously cut each bag one by one, the bags are wrapped individually and continuously dropped into the hopper of the lower discharge section. When a considerable number of them were formed, they were to be discharged outside.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, one bag is required for each wet towel, which affects the cost, and the wet towels dropped into the hopper become disorderly, causing another bag to be used. There was a problem in that it was necessary to count and refill containers and organize them by hanging them with bands, which required high labor costs.

The present invention aims to eliminate such problems of the prior art.

(Means for Solving the Problems) In order to achieve the above object, the present invention installs an alignment part and an elevator part under the upper and lower seal cut parts, and gives a slight swing in the up and down, front, back, left and right directions. This device has the function of arranging a plurality of diapers, putting them all together in a bag, and sealing it.

(effect) The invention works as follows.

For example, as shown in the internal side view of the diaper winding and packaging machine in FIG. The aligning section 6 installed under the upper and lower seal cut sections 5 counts the number of wet towels 10 that continuously fall into the bag 12 formed in step 11, and the aligning section 6 installed under the upper and lower seal cut sections 5 counts the number of wet towels 10 that fall continuously into the bag 12 formed in step 11, and the aligning section 6 installed under the upper and lower seal cut sections 5 counts the number of wet towels 10 that fall continuously into the bag 12 formed in step 11. The wet towels 10 are arranged in a bag 12. And the elevator section 7 below
The bag 12 is lowered step by step, and an arbitrary number of wet towels 10 are put into the bag and cut while being sealed with the upper and lower seal cut parts 5.

(Effects of the Invention) The present invention has the following effects because it is configured and operates as described above.

By arranging the arbitrary number of diapers counted in one bag and putting them all together, the conventional technology required one bag for each diaper, but now only one bag is needed for multiple diapers. Costs are reduced, and there is no longer a need to count and refill wet towels dropped into a separate container into a separate container, or to organize them with bands, which can reduce labor costs. .

Further, the elevator section 7 includes an elevator base 7a that moves up and down supported by four elevator bases 7b... rotated by eight Cheno wheels 7d... installed on four shafts 7C... , motor 7g and shaft 7
The motor 7g consists of three driving wheels 7e attached to the lower two wheels c... and the shaft of the motor 7g, and a driving wheel 7f that connects and rotates them. According to the rotation of the base 7a, the base 7a can be moved up and down.

The elevator section 7 places the bag 12 on the vertically movable plate 6p on the elevator base 7a, and gradually lowers the bag 12 as the wet towels 10 come in.

FIG. 8 is a perspective view of the discharge section 8.

The ejecting section 8 consists of an extrusion plate 8b fixed at the rear to the extrusion cheno 8c, a shaft 8d, and a motor 8e.The motor 8e rotates to drive the extrusion chino 8C connected to the shaft 8d by a sprocket or a driving chino. Rotate to move the push-out plate 8b back and forth.

When the bag 12 containing wet towels 10 placed on the vertically movable plate 6p on the elevator base 7a comes to the front of the push-out plate 8b, the motor 8e is rotated to push the push-out plate 8b forward and discharged to the outside.

Further, photoelectric sensors 9a and 9b placed directly below the winding section outlet 1h count the number of wet wipes 10 that continuously fall into the bag 12 one by one from above, and activate each mechanism at set timings. Then, an arbitrary number of 10 diapers are packed together in one bag.

The diaper winding and packaging machine according to the embodiment of the present invention configured as described above is such that even if the baby diaper 10 is not rolled uniformly and tries to be slanted, it is temporarily stopped at the winding force release part 1g in the middle, and the winding progresses. While automatically correcting the drifting direction, the winding section 1 winds up the diapers, and the photoelectric sensors 9a and 9b placed directly below the winding section exit 1h count the continuously falling bottoms 10 one by one. A bag 12 containing wet towels 10 is received by the elevator base 7a of the elevator section 7, and while a desired number of wet towels 10 are placed in the bag at once, the alignment section 6 gives a slight swing in the up and down, front, back, left and right directions. A plurality of butts 10 are arranged in a row.

If there is no alignment part 6, as shown in FIG. 10A, the bag 1
Since the towels 10 are stacked vertically in the bag 12, the bag 12 becomes large, and later the towels 10 collapse inside the bag 12, and the product value of the towels 10 that have been rolled up is lost.

In order to prevent this from happening, the alignment section 6 is provided to neatly and neatly align the wet towels 10 inside the bag 12 before sealing the bag 12 as shown in Figure B.

When an arbitrary number of wet towels 10 are collected in a bag 12, the bag 12 is sealed by the upper and lower seal cutting parts 5, the upper and lower parts are cut, the bag is packaged, and the bag is discharged to the outside by the extrusion plate 8b of the discharge part 8.

In another embodiment of the alignment section 6, the longitudinal swing mechanism 6a and the vertical swing mechanism 6b are combined into one mechanism to form a diagonal swing mechanism 6d, and FIG. 9 is a side view thereof.

The diagonal swinging mechanism 6d of the alignment section 6 includes a vertically moving plate 6p of the vertically swinging mechanism 6b and a pair of vertically moving solenoids 6q.
6q and a slide pin 6r provided on the elevator base a, but
Upper and lower solenoids 6q, 6q and slide pin 6r...
is attached to the elevator base 7a with an inclination in the front-rear direction, and the vertically movable plate 6p can be moved diagonally up and down.

The back-and-forth swing mechanism 68 can be constructed by simply installing the frame 6m and the sponge 6 in a fixed manner, and other mechanical parts can be omitted.

Since the diagonal swinging mechanism 6d of the alignment section 6 having such a configuration operates diagonally up and down by intermittently energizing the pair of vertical solenoids 6q, 6q, the vertical movement plate 6p swings diagonally. The same effect as moving in the up-down direction and the front-back direction can be obtained by applying a slight swing diagonally up and down to the wet towels 10 that continuously fall one by one into the bag 12 from above and aligning them. I can do it.
