Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a sanitary napkin in which a predetermined number of individually packaged sanitary napkins are packaged in series. It relates to a separation packaging device.

[Prior Art] This type of conventional sanitary napkin separation and packaging apparatus involves rolling up continuously supplied sanitary napkins with a packaging film, and then rolling up the sanitary napkins in a winding section when individually packaging sanitary napkins. A film is sealed in the flow direction of the sanitary napkin, the -H sanitary napkin is wrapped with the film, and the front and back of the sanitary napkin are further sealed, respectively.

Next, each sanitary napkin was separated one by one, and then packed into bags in the number of sales units. Therefore, conventional devices of this type have a counting and separating mechanism that counts and captures the sanitary napkins in sales units one by one and separates the sanitary napkins for each sales unit, and an accumulation mechanism that collects the sanitary napkins for each sales unit. Each was prepared individually.

Further, as the conventional mechanism for sealing the film before and after the sanitary napkin in the film winding section, an impulse sealing method using a chain feeding mechanism is used. This mechanism separates the individually wrapped sanitary napkins one by one at the outlet of the chain feeding mechanism after completing the individual wrapping of the sanitary napkins.

[Problem to be solved by the invention]

However, in the case of conventional sanitary napkin separation and packaging equipment, when trying to speed up the separation and packaging of sanitary napkins, the feeding mechanism that seals the film before and after the sanitary napkin is a chain mechanism as described above. Vibrations become intense, which tends to cause variations in seal strength.
Moreover, there was a problem in that the vibration generated a large amount of noise.

In addition, even when separating sanitary napkins one by one at the outlet of the chain feeding mechanism, the sanitary napkin receiver has a long passing distance, and there may be pitch deviations or misalignment between the continuously supplied sanitary napkins. There was a problem in that it was easy to tilt in the direction.

Furthermore, since the counting and separation mechanism requires the operation of checking sanitary napkins one by one, there is a limit to the number of sanitary napkins that can be counted and confirmed when speeding up separation packaging. When trying to perform high-speed processing exceeding 500 pieces/min, there was a problem in that counting errors were more likely to occur.

Therefore, an object of the present invention is to provide separate packaging for sanitary napkins that can reliably and quickly separate and package a plurality of sanitary napkins one by one with a constant sealing strength, and can also package these as separable packages at high speed. The goal is to provide equipment.

[Means for Solving the Problems] The present invention includes an end sealer, a cutter, an accumulation section,

A plurality of end seal portions are formed on the film to separate and individually package each sanitary napkin, and the cutter includes a cutting portion and a perforation portion, and the cutter is configured to seal the ends of the plurality of sanitary napkins. The seal portion is cut at least every other time by the cutting portion to create a packaging high speed in which at least two sanitary napkins are arranged in series, and the other end seal remains on the packaging speed by the perforation providing portion. The stacking section stacks and stacks a predetermined number of the high-speed packaging having the perforations, and then supplies the stacked packages to the packaging machine, and the packaging machine collects the predetermined number of stacked packages. The above object has been achieved by providing a sanitary napkin separation and packaging device that is characterized by high-speed packaging.

[Function] According to the present invention, an end sealer is used to form end seal portions at the front and back of each sanitary napkin in a film that integrally wraps a plurality of sanitary napkins that are continuously supplied in a vertical line, thereby sealing each sanitary napkin individually. When the sanitary napkins are separated and individually packaged, at least every other end seal part is cut by the cutting part of the cutter to create a packaging high speed in which at least two sanitary napkins are connected, and this cutting is also carried out. After applying perforations to the other end seal parts remaining on the packaging high speed using the perforation section of the canter in between, a predetermined number of packaging high speeds are stacked and stacked using the stacking section and then fed to the packaging machine. Depending on the machine, it is possible to package a predetermined number of high-speed packages at once.

It is configured.

Further, the packaging machine 50 is constituted by a conventionally known mechanism (not shown) that individually wraps the seven packaging high speeds 300 supplied by the stacking section 40.

Next, the operation of the sanitary napkin separation and packaging apparatus of this embodiment will be explained.

First, when the supply conveyor 60 supplies the sanitary napkin 100 produced in the previous process to the sealer 80, the film supply section 70 supplies the film 200 to the sealer 80 in parallel. The sealer part 80 welds the film 200, which wraps a plurality of supplied sanitary napkins 100 in a column, at the center of the sanitary napkin 100 in the width direction in the flow direction, so that the sanitary napkin 100 does not deviate from the line. . Next, end sealer 20
At the front position of the sanitary napkins 100 that are successively flowing down, the heating part 11A of the heating roll 11 is pressed down onto the surface of the roll 12 so that the film 200 is sandwiched therebetween, and the film 200 is welded to form the end seal part 201.

Subsequently, the heating roll 11 and the roll 12 of the receiver are 120
When the sanitary napkin 100 flows down by a distance corresponding to one piece while rotating, the next heating part 11A of the heating roll 11 and the receiving roll 12 form an end seal on the film 200 at the rear position of the sanitary napkin 100. 201 is formed.

Thereafter, in the same manner, end seal portions 201 are formed on the film 200 at the front and rear of each sanitary napkin 100, and the sanitary napkins 100 are separated from each other and individually packaged. Thereafter, the cutter 30 pushes the cutting blade 2LA of the rotary cutter 21 onto the surface of the roll 22 so as to sandwich the end portion 201 of the film 200 at a position in front of the individually wrapped sanitary napkins 100 flowing down. to separate the sanitary napkin 100 by cutting at the end seal portion 201. Subsequently, while the rotary cutter 21 and receiving roll 22 rotate 120 degrees, the sanitary napkin 100 is allowed to flow down by a distance corresponding to one sanitary napkin. A perforation 2 is given to the end seal part 20+ at the rear position of the napkin 100, and furthermore, the rotary cutter 21 and the roll 22 of the receiver are rotated 120 degrees, and the next perforation blade 21B and the receiver are the roll 22. Add one perforation.

Then, when the roll 22 rotates once, the rotary cutter 21 and the receiver reactivate the cutting blade 21 of the rotary cutter 21.
A reaches the end seal part 201 and separates the sanitary napkin 100 in the same manner as described above, and the three individually wrapped sanitary napkins 100 are connected by perforations.
Packaging high speeds 300 are made and the packaging high speeds 300 are sequentially delivered to the conveyor 30. The conhair 30 separates the packaging high speeds 300 sequentially received from the cutter 20 by a certain distance and conveys them to the downstream side, and supplies each packaging high speed 300 one by one to the stacking section 40. Then, in the conveyor 30, every time the position detector 91 detects a gap formed between the packaging high speeds 300 and 300 flowing down sequentially, it sends the signal to the controller 90, and the controller 90 receives this detection signal. The drive mechanism 43 is driven based on the support body 41.
The packaging high speed 300 is sequentially accumulated in the housing 41 one by one by moving the housing 41 through the housing. Along with this accumulation operation,
The housing position detector 93 stores the rotation angle, and when the seven packaging high speeds 300 are integrated in the housing 41, the housing position detector 93 sends a signal to that effect to the controller 90. The controller 90 selects the next housing 4 based on this signal.
1, the drive mechanism 43 is driven to receive and pick up the packaging high speed 300 to be newly accumulated. The accumulating unit 40 stores seven packaging high speeds 300 in each case 4 as described above.
1, the housing 41 is gradually rotated by the drive mechanism 43 under the control of the controller 90, and the seven packaging high speeds 300 are supplied as one unit to the packaging machine 50. The packaging machine 50 receives the packaging high speeds 300 in groups of seven from the stacking section 40, and then wraps the high speed packaging 300 in units by a conventionally known method.

According to the device of the invention, for example, the individual packaging speed is 1.20
Packaging is possible at 0 pieces/minute, and this individual packaging speed is about twice that of conventional devices of this type.

In the above embodiment, a heating type end sealer 10 is used, but the end seal portion 201 can be similarly formed by a conventional film welding method such as an ultrasonic method.

In addition, in the above embodiment, three sanitary napkins 100 are arranged in a row, but the sanitary napkins 10
The number of consecutive 0's can be changed as necessary.

Further, in the above embodiment, only the case in which seven packaging high speeds 300 are stacked has been described, but the number of packaging high speeds 300 that are stacked can be changed as necessary.

Further, although the present invention relates to a separating and packaging device for sanitary napkins, it goes without saying that the present invention can also be applied to separating and packaging items other than sanitary napkins as needed.

〔Effect of the invention〕

The sanitary napkin separation and packaging device of the present invention is capable of separating and packaging a plurality of sanitary napkins one by one reliably and at high speed with a constant sealing strength, and also packaging them as separable packaging at high speed. be.
