Conveyor. Reference numeral 2 denotes an end of the intermittent transfer conveyor 1, which moves the superposed paper S on the intermittent transfer conveyor 1 in a direction perpendicular to the transfer direction of the intermittent transfer conveyor 1, and then substantially extends the transfer direction of the intermittent transfer conveyor 1. This is a flight conveyor for supplying a bucket conveyor 3 for transferring to a position corresponding to an automatic horizontal box packing machine 4 to be described later, which is located above, and the flight conveyor 2 transfers the superposed paper S at the end side of the intermittent transfer conveyor 1. A guide table 2a that supports and guides to a predetermined position; a plurality of guide rails 2b that are inclined downward from the end of the guide table 2a and guide the downward while supporting the superposed paper S on the upper surface thereof; A contact portion 2d where the leading end of the superposed paper S transported by the intermittent transport conveyor 1 is abutted at the end of the intermittent transport conveyor 1.
And an L-shaped transfer body 2c which is provided at one of the abutting portions 2d by being bent at a right angle and comprises a pressing portion 2e for pressing the side surface of the superposed paper S abutting on the abutting portion 2d; The transfer body 2c is fixed to a hanging bar 2g that protrudes from the rotating upper chain 2f and is suspended from the contact surface of the transfer body 2c with the side surface of the superposed paper S, and the L-shaped transfer body 2c of the hanging bar 2g On the opposite side, the contact part 2d of the L-shaped transfer body 2c is bent, and the pressing part 2e of the adjacent L-shaped transfer body 2c is pressed when the pressing parts 2e of the adjacent L-shaped transfer body 2c are parallel to each other.
The cross-sectional shape provided with the width regulating surface 2i in which the distance between the side surface of the superposed paper S and the contact surface thereof is substantially the same as the width of the superposed paper S is deformed U
It consists of a guide plate 2h shaped like a letter.

A fixed portion A that forms a surface parallel to the mold transfer body 2c, a bent portion B that is bent at an acute angle from a tip of the fixed portion A protruding on the opposite side to the rotating upper chain 2f, If it is composed of the rear end of the curved portion B and the width regulating surface 2i parallel to the fixed portion A, the superposed paper S intermittently transported by the intermittent transport conveyor 1 is brought into contact with the L-shaped transport body 2c. When the side of the superposed paper S abutting on the abutment portion 2d is pressed by the pressing portion 2e by contact with the portion 2d and the movement thereof is stopped, the superposed paper S is moved in the transport direction of the intermittent transport conveyor 1. Even if the superposed paper S is transported with the side surface slightly inclined, the presence of the bent portion B bent at an acute angle from the tip protruding on the opposite side of the rotating upper chain 2f of the fixed portion A causes intermittent operation. The contact portion 2d of the L-shaped transfer body 2c and the guide plate 2h which contact the side surface of the superposed paper S intermittently transferred by the transfer conveyor 1 The width between the bent part B and the width regulating surface
No problem occurs because the distance from 2i is sufficiently large.

3 is a guide table 2a of the flight conveyor 2.
After being moved by being pressed by the pressing portion 2e of the L-shaped transfer body 2c, the L-shaped transfer body is supported by the upper surfaces of a plurality of guide rails 2b inclined downward from the end of the guide table 2a. The overlap which is pressed by the pressing portion 2e of 2c and held on the opposite side of the pressing portion 2e of the L-shaped transfer body 2c by the width regulating surface 2i of the guide plate 2h having a modified U-shape and guided downward. The paper S is inserted, and the front and rear surfaces for transporting the superposed paper S to a position corresponding to the automatic horizontal box packaging machine 4 positioned substantially in the transport direction of the intermittent transport conveyor 1 are open, and A bucket conveyor provided with buckets 3a provided with slits 3b on both side walls standing upright with substantially the same width as the width, and guiding the flight conveyor 2 to slits 3b provided on both side surfaces of the buckets 3a. Inclined downward from the end of table 2a A plurality of guide rails 2b there are inserted.

Reference numeral 4 denotes an opening in the front of the bucket 3a of the bucket conveyor 3 in which the superimposed paper S has been stored and moved. The automatic horizontal box-type packaging machine 4 for pushing into the packaging box from the outside is located substantially on the extension of the intermittent transfer conveyor 1 in the transfer direction.

In the apparatus for transferring superposed paper folded and engaged with each other to the automatic horizontal box packing machine according to the present invention having such a structure, the fold is transferred onto the intermittent transfer conveyor 1. An intermittent transfer conveyor 1 is provided in which the superposed paper S, which has been transferred in a straight line while being placed at regular intervals in a state parallel to the direction, is folded in two and engaged with each other.
Of the flight conveyor 2 driven in synchronization with the intermittent transfer conveyor 1 when the end of the
The leading end of the superposed paper S abuts on the contact portion 2d of the L-shaped transfer body 2c fixed to the hanging bar 2g protruding from 2f and hung, and the movement thereof is stopped. One side of the contact portion 2d is provided to be bent at a right angle, and the side of the superposed paper S which is in contact with the contact portion 2d by the pressing portion 2e is pressed, and the superposed paper S is transferred by the intermittent transfer conveyor 1. The direction of movement is continuously changed while being supported by a guide table 2a provided at the end side of the intermittent transfer conveyor 1 in a direction perpendicular to the direction, and is continuously changed to a predetermined position, that is, a plurality of guide rails 2b. You will be guided to the location.

At this time, since the rotating upper chain 2f for moving the L-shaped transfer body 2c and the L-shaped transfer body 2c are fixed by the hanging bar 2g protruding from the rotating upper chain 2f and hanging down, The distance between the pressing portion 2e of the adjacent L-shaped transfer body 2c and the width regulating surface 2i of the guide plate 2h having the U-shaped cross section of the L-shaped transfer body 2c is at the end position of the intermittent transfer conveyor 1. The portion of the L-shaped transfer body 2c that is sufficiently wider than the width of the superposed paper S and that makes contact with the superposed paper S is a contact portion 2d and a pressing portion 2e.
Since only two sides are used, even when the superposed paper S is slightly inclined to the side, a phenomenon occurs in which a part of the superposed paper S is bent, a part of the superposed paper S is dropped, or the whole is turned over. Without being guided by the guide table 2a, it is guided to a predetermined position, that is, a position of a plurality of guide rails 2b.

Thus, the superposed paper S guided to the positions of the plurality of guide rails 2b is pressed on the side surface by the pressing portion 2e of the L-shaped transfer body 2c, and is guided downward on the plurality of guide rails 2b. But this guide rail 2b
Is in a straight line, the rotating upper chain 2f for moving the L-shaped transfer body 2c and the rotating upper chain 2f for moving the L-shaped transfer body 2c.
Since it is fixed by the hanging bar 2g which protrudes and hangs down, the pressing portions 2e and L of the adjacent L-shaped transfer body 2c are fixed.
Since the space between the guide plate 2h and the width regulating surface 2i of the guide plate 2h having the deformed U-shaped cross section is substantially the same as the width of the superposed paper S, the superposed paper S is transported by the adjacent L-shaped transport. Both sides are pressed by the pressing portion 2e of the body 2c and the width regulating surface 2i of the guide plate 2h in which the cross-sectional shape of the L-shaped transfer body 2c forms a deformed U-shape. It is maintained in a state of being adjusted to.

The bucket of the bucket conveyor 3 is driven below the guide rail 2b in synchronization with the intermittent transfer conveyor 1 and the rotating upper chain 2f of the flight conveyor 2.
Since the position of the slit 3b provided in 3a and the position of the guide rail 2b coincide with each other, the superposed paper S is transported in an L-shape while the superposed paper S is guided downward on the plurality of guide rails 2b. When the bucket 3a is gradually lowered from the body 2c and is inserted into the bucket 3a of the bucket conveyor 3 and the lower end of the guide rail 2b passes through the bucket 3a, the bucket 3a surely fits into a predetermined position in the bucket 3a. Of both sides are superimposed paper S
Is superposed so as to have the same width as that of the superimposed paper S, so that the superposed paper S can be inserted into the packaging box as it is.

In this state, the bucket of the bucket conveyor 3
When 3a is moved to a position corresponding to the automatic horizontal box packing machine 4 located substantially on the extension in the transfer direction of the intermittent transfer conveyor 1, the pusher 4a of the automatic horizontal box packing machine 4 moves the front surface of the bucket 3a. The superimposed paper S inserted into the bucket 3a from the opening of the bucket 3a and packed in the bucket 3a is positioned at the rear side of the bucket 3a from the opening of the packaging box having one longitudinal side open. Insert it into the box.

[0017]

As described in detail above, the apparatus for transferring the folded papers, which are folded and engaged with each other, to the automatic horizontal box packing machine according to the present invention is a device for transferring tissue paper, paper towels and kitchen paper. In order to pull out the sheets one by one or one set at a time from the take-out opening of the packaging box, the superposed paper folded in two and engaged with each other at regular intervals in a state where the folds are parallel to the transport direction. The intermittent transfer conveyer, which is transferred in a straight line while being placed, is transferred to a position corresponding to an automatic horizontal box packaging machine. At the end of the transfer conveyor, the superposed paper on the intermittent transfer conveyor is moved in a direction perpendicular to the transfer direction of the intermittent transfer conveyor, and then supplied to the bucket of the bucket conveyor. By adopting a flight conveyor having a specific structure and a bucket having a specific structure of a bucket conveyor as a step, a part of the superimposed paper is bent or partially dropped when the superimposed paper is inserted into the bucket of the bucket conveyor. Or the entire package may fall over, and the automatic horizontal packaging machine will not enter the desired state due to a defective number, a diagonal insertion, or a vertical insertion into the packaging box. It can be prevented.

That is, as a means for stopping the movement of the superposed paper on the intermittent transfer conveyor at the end of the intermittent transfer conveyor, moving the superposed paper in the direction perpendicular to the transfer direction of the intermittent transfer conveyor, and then supplying the paper into the bucket of the bucket conveyor. Of the superposed paper conveyed by the intermittent conveyer is contacted with the leading end of the superposed paper, and is bent at a right angle to one of the contacting parts. An L-shaped transfer body comprising a pressing portion for pressing the side surface of the overlapped paper is used, and the connection between the rotating upper chain that drives the L-shaped transferring body and the L-shaped transferring body protrudes from the rotating upper chain and is hung down. The hanging bar is used to stop the movement of the superimposed paper on the end of the intermittent transfer conveyor, and to move in the direction perpendicular to the transfer direction of the intermittent transfer conveyor and to be adjacent to the L-shaped transfer body pressing portion. In the vicinity of the end of the intermittent transfer conveyor, the width of the superposed paper is sufficiently larger than the width of the superimposed paper and the space between the superposed paper of the L-shaped transport body and the superposed paper is close to the end of the intermittent conveyor. Since the contacting part is only the two surfaces of the contact part and the pressing part, even if the superposed paper is slightly inclined to the side, a part of the superposed paper is bent, a part is dropped, Without the phenomenon of falling over, the overlapping paper comes into contact with only the two surfaces of the contact portion and the pressing portion, and the surface of the opposite side of the overlapping paper that is in contact with the pressing portion and the deformation U In a state in which the gap between the guide plate and the width regulating surface of the letter-shaped guide plate is wide, the superposed paper is supported by a horizontal guide table and guided to a predetermined position, that is, a position of a plurality of guide rails. Guides inclined to supply superimposed paper inside When the superposed paper is transferred onto the roll, the superposed paper has a deformed U-shaped cross section of the pressing portion of the L-shaped transport body and the L-shaped transport body adjacent to the L-shaped transport body. Since the interval between the guide plate and the width regulating surface is substantially the same as the width of the superposed paper, both sides of the superposed paper are pressed by the pressing portion of the L-shaped transfer body and the width regulating surface of the guide plate, so that the superposed paper is pressed. When the overlapping paper is supplied into the bucket of the bucket conveyor, the slits are formed on both side surfaces of the bucket without causing the phenomenon that a part of the paper is bent, a part of the paper falls, or the whole falls. Are provided and a plurality of guide rails for guiding the superposed paper to the bottom of the slit of the bucket are inserted, so that the superposed paper does not fall from a high place to the bottom of the bucket, and both side walls of the bucket are heavy. Because the stacking paper stored in the bucket does not bend partially, drop off, or fall down entirely, the stacked paper stored in the bucket does not occur because it is set up approximately the same width as the tatami paper. No phenomena such as poor entry, diagonal insertion, and vertical insertion do not occur.

The industrial value of the apparatus for transferring the folded papers, which are folded and engaged with each other, according to the present invention, which has such an effect, to the automatic horizontal box packing machine is very large.
