Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting and conveying device for disposable products.

In the conventional manufacturing of tissue products, the tissue strip is bent, cut approximately at the center, and the cut tissue strips are manually transferred in predetermined numbers to a conveyor belt to be sent to a packaging device. was. Since it was done manually, there were problems such as inconsistency in transfer speed and placement intervals.

The present invention provides a gutter that guides the folded tissue belt, a cutting blade that cuts the folded tissue strip in the gutter approximately at the center, a rear partition plate that can enter and exit from both sides of the gutter, and a front A partition plate is provided, and an upper partition plate is provided so as to be movable up and down with respect to the guide surface of the gutter, and a group of cuts is divided into a predetermined number by the upper partition plate and held between the front partition plate and the rear partition plate. The resulting tissue strip is sucked up at the end of the gutter,
This is characterized by the provision of a suction device for transferring to a conveyor belt.

Embodiments of the present invention will be described below with reference to the drawings.

The tissue sheet is folded on one side to form a tissue belt 1, and the tissue belt 1 is intermittently guided between folding rollers 2 and 3 that alternately rotate in opposition to each other, and the tissue belt 1 is folded while passing through the first guide gutter 4. send it into the.

When folding the tissue belt, the bottom plate 5 in contact with the tissue belt 1 is intermittently raised, and the tissue belt 1 to be folded is folded so as to protrude upward 1a every eight folds, for example.

A slit is provided at the rear end of the first guide trough 4, and a portion of the endless cutting blade 6 is provided through the slit. The folded tissue belt 1 is now cut in half.
In the cut state, the bi-folded tissues are stacked along the guide gutter. In this state, it is sent backward by the folding pressure.

The second guide trough 7 is supported by spring means and is arranged to form one continuous trough at the rear end of the first guide trough 4. Second guide trough 7
A separation wall 8 is erected at the rear end thereof toward the cut point of the cut tissue band 1.

Since the second guide trough 7 is supported by the vibration generating means 9, the tissue strip 1 to be cut reaching the second guide trough 7 is sent by vibration. A suction unit 10 of the suction device is provided at the terminal end of the second guide trough 7 so as to move between a suction position A and a release position B. To be exact, suction part 1
0 moves rearward from the suction position A shown by the solid line in FIG. 2, then rotates downward to take the release position.

Furthermore, a plurality of partition plates 11 are provided at the rear end of the second guide gutter 7 so as to be able to move in and out toward the guide gutter, and the timing of their appearance and retraction is controlled by an air cylinder.

The relationship between each partition plate 11 and the suction section 10 will be explained.

When the suction unit 10 moves to the suction position A, the rear partition plate 11a retreats from the guide gutter, and the upper partition plate 1
1c presses the upwardly projecting tissue strip 1a, and the front partition plate 11b is inserted between the cut tissue strips 1a. As a result, a group of tissues 1b defined as a predetermined number are held between the suction unit 10 of the suction device and the front partition plate 11b and are sucked. The rear partition plate 11a is located at the final end of the second guide trough 7 and is provided so as to appear and retract in the horizontal direction. They are provided so as to appear and retract toward the guide gutter in the horizontal direction at intervals equal to the thickness.

After the suction unit 10 suctions the group 1b of the cut tissue bands 1 partitioned by the front partition plate 11b,
The suction unit 10 rotates downward while moving slightly horizontally. During this time, the rear partition plate 11a protrudes toward the guide trough 7 side, and after waiting for the next station 1b group to be held, the front partition plate 11b, which has been holding the next station 1b group, is moved. can be retracted from guide trough 7. As a result, the next group of tissues 1b is held on the rear partition plate 11a. During this time, the upper partition plate 11c moves to the rear end of the guide trough 7, and then moves to the front end side of the guide trough 7 to hold down the tissues protruding from the troughs and separate them into a predetermined number of sheets. Moreover, the rotary claw 12 located below the guide trough 7 rotates and assumes a position where it comes into contact with the lower side of the cut tissue band 1. Due to these, the tissue belt 1 can freely move to the rear end of the guide trough 7. The cut tissue strip 1 is polymerized and advanced under a constant pressure in the second guide trough 7 due to vibrations applied to the second guide trough 7, so that the partition plates 11a,
An equal number of cut tissue bands are defined between the sections 11b. The means for pushing the cut tissue band 1 forward with a constant pressure may be other than vibration.

A group of tissue strips 1b sucked by the suction section 10 of the suction device are dropped onto the belt conveyor 13 by exhaust gas from the suction device. Thereafter, the suction unit 10 of the suction device returns from position B to position A, and repeats the operation described above to suction the group of cut tissue bands 1b at the end of the guide trough 7.

As described in detail above, the present invention separates the cut tissue strips into a predetermined number of sheets using upper and lower partition plates, and the tissue groups in which the number of sheets has been arranged are narrowed between the front partition plate and the rear partition plate and are sucked into the suction device. As a result, a predetermined number of disposable products are reliably held in a defined manner without changing their posture and are sucked into the suction device, making it possible to mechanically separate the disposable products, which has been difficult in the past.

Claims (1)

[Claims] 1. A gutter that guides the bent tissue band, a cutting blade that cuts the bent tissue band in the gutter approximately at the center, and a rear partition plate and a front partition plate that can enter and exit from both sides of the gutter. At the same time, an upper partition plate is provided so as to be movable up and down with respect to the guide surface of the gutter, and a group of cut tissues are partitioned into a predetermined number by the upper partition plate and held between the front partition plate and the rear partition plate. This is a sorting and conveying device for disposable products, which consists of a suction device that sucks up the strips at the end of the gutter and transfers them to a conveyor belt.
