Abstract

PURPOSE:To facilitate sorting of tissue product by grouping the cut strips of tissue band using two or more partition walls coming in and out and by transferring each group of strips to a transport device by means of suction. CONSTITUTION:A group of strips 1b cut from a tissue band 1, which are grouped by a front partition wall 11b, is attracted by a suction part 10, and this part turns downward while moving a little horizontally. Meanwhile the rear partition wall 11a protrudes toward a guide gutter 7, and the front partition wall 11b draws in from the guide gutter side 7 after waiting for this protrusion of rear partition wall 11a. The upper partition wall 11c moves till the tail of the guide gutter 7, and a rotary nail 12 situated below the guide gutter 7 rotates to take a position in contact with the lower edge of the cut tissue band 1. This tissue band 1 advances in overlapping because of vibration of No. 2 guide gutter 7 and forms groups of strips cut from the tissue band in the same number between the partition walls 11a and 11b. On the other hand, another group of strips 1b attracted is transferred onto a belt conveyor 13.

Description

[Detailed description of the invention] The present invention relates to an apparatus for separating and conveying tissue products.

In the conventional manufacturing of tissue products, a 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 going on. Because it is done by hand,
There were problems such as inconsistency in transfer speed and placement intervals.

The present invention relates to a waste tissue product sorting and conveying device that automatically breaks tissue strips and transfers them to a conveying device. The tissue is characterized in that the tissue is divided into a predetermined number of sheets at the end, and the tissue is suctioned at the end of the guide gutter and transferred to a conveying device.

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

Fold the tissue sheet to one side and place the tissue strip 1.
The tissue strip 1 is guided between folding rollers 2.3 that rotate intermittently and alternately in opposition to each other.
is sent into the first guide gutter 4 while being folded.

When folding the tissue band, the bottom plate 5 with which the tissue band 1 comes in contact is intermittently raised, and the tissue band 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, through which a portion of the endless cutting blade 6 passes. The folded tinny strip 1 is now cut in half. In the cut state, the two folded tissues are stacked along the guide trough. They are arranged to form one continuous gutter. At the rear end of the second guide trough 7, a separation wall 8 is provided erected toward the cut location of the cut tissue strip 1.

Since the second guide trough 7 is supported by the vibration generating means 9, the cut tissue reaching the second guide trough 7 is
Band 1 (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 precise, the suction unit 10 moves backward from the suction position A shown by the solid line in FIG. 2, and then rotates downward to take the release position.

Further, a plurality of partition plates 11 are provided at the rear end of the second guide gutter 7 so as to be freely protrusive and retractable toward the guide gutter, and the timing of their protrusion and retraction is controlled by an air cylinder.

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

When the suction unit 1D moves to the suction position, the rear partition plate 1
1a retreats from the guide trough, the upper partition plate 11C presses down the tinny band 1a protruding upward, and the front partition plate 1
1b is inserted between the cut dish-strips. 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 that they appear and disappear horizontally toward the guide ripples at intervals equal to the thickness.

After the suction section 10 suctions the group 1b of cut tissue bands 1 partitioned by the front partition plate 11b, the suction section 10 rotates downward while moving slightly horizontally. During this time, the rear partition plate 11a protrudes toward the guide gutter Z side, and the rear partition plate 11a
Waiting for the appearance of the guide @l, the front partition plate 11b retracts from the guide gutter 7 side, and the upper partition plate 11c moves to the rear end of the guide gutter 7, and the guide @l! ! A rotating claw 12 located below 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 band 1 can freely move to the rear end of the guide trough 7. The cut tissue strip 1 is overlapped and advanced under a constant pressure in the groove by the vibration applied to the second guide trough 7, so that an equal number of cut tissue strips are placed between the partition plates 11a and 11b. A tissue band will be defined. The means for pushing the cut tissue strip 1 forward with a constant pressure may be other than photographing.

Some tissues sucked by the suction unit 10 of the suction device
The FJ1 bid is dropped onto the belt conveyor 13 by exhaust from the suction device. after that,
The suction unit 1o of the suction device returns from the position B to the position A, and repeats the operation of suctioning the partially cut tissue band 1b at the end of the guide trough 7 in the above-described operation.

As described above, the present invention is configured so that a cut tissue band is defined by a plurality of partition plates that come and go, and a part of the defined tissue band is sucked and conveyed, which is difficult to do in the past. This made it easier to separate tissue products, which were considered to be
