Five cutouts 52 are formed in a corresponding to the rows of the articles P. The width of the cutout 52 is smaller than the width of the article P in the lateral direction, and the pressing plate 44 is inserted into the cutout 52. The lower portion 43a of the push-out plate 43 is formed so as to be heavier than the upper portion 43b and is vertical in a natural state. Also, axis 5
1 is supported by a bracket 46 so that it can be moved and adjusted in the carrying direction, and the initial position for pushing out the article P can be changed,
The number of the articles P pushed out can be changed.

The push-out plate 43 contacts the article P when it is pushed out and does not hinder the progress of the article P when it returns, so that a contact member 53 for restricting the rotation of the push-out plate 43 is provided. ing. The abutting member 53 is movably attached to the horizontal groove 54 of the pressing plate 44 with the bolt 55 and the nut 56, and the position thereof can be displaced with respect to the transport direction according to the change of the initial position of the pushing plate 43.

When the article P is pushed out, as shown in FIG. 6A, the pushing plate 43 comes into contact with the article P and tries to rotate in the direction A, but comes into contact with the abutment member 53 and its rotation is restricted. Therefore, the article P can be pushed out in the transport direction. On the other hand, when the push-out plate 43 returns to the original position, that is, when the push-out plate 43 moves in the direction opposite to the conveying direction, the push-out plate 43 comes into contact with the next conveyed article P as shown in FIG. 6B. Also, since it also rotates in the B direction, it is possible to return to the original position without hindering the progress of the article P. Further, even when the push-out plate 43 is at the initial position and the article P is transported from the transport conveyor 19 to the parallel conveyor 29, the same action does not hinder the progress of the article P.

The approaching means comprises a pair of approaching bars 57 for bringing the articles P on both sides into contact with each other and bringing the article P to the center, and a width adjusting mechanism for moving the approaching bars 57 close to and away from each other according to the movement of the pushing plate 43. . The draw bar 57 is formed in a substantially T shape,

The width-shifting mechanism includes a roller 60 rotatably supported by the shifting bar 57 and a cam 61 attached to the bracket 46 and in contact with the roller 60. The roller 60 of the shifting bar 57 is moved by the movement of the pushing plate 43. By rolling the inclined surface 61a of the cam 61, the pulling rods 57 move inward toward each other and approach each other, and the articles P on the parallel conveyor 29 are gathered toward the center while being aligned. It should be noted that the gathering means is not limited to one that brings the article P to the center,
It may be one sided.

The drive of the cylinder and motor is
It is automatically controlled by the sequencer or microcomputer. That is, when a predetermined number of articles P are aligned in a row of the parallel conveyors 29, the conveyors 19 corresponding to the row are stopped and the stoppers 27 at the entrances and exits thereof are provided.
28 is raised and closed. In addition, when the number reaches a predetermined number in all rows, the restriction stopper 41 is lowered to open the exit of the parallel conveyor 29, and the push-out plate 43 is moved to push out the articles P to align them with each other. Further, when the above-mentioned pushing operation is completed, driving of the conveyor 19 is started,
The doors are opened by lowering the stoppers 27 and 28, and the outlet of the parallel conveyor 29 is closed by raising the restriction stopper 41. By controlling such a series of operations, automatic operation is possible.

With the above structure, the articles P are fed to the supply conveyor 9.
When the product P is supplied, the product P is conveyed by the supply conveyor 9 in a disordered state, and the regulation bar 10 removes the overlap of the product P. When the article P passes under the chain 16 and reaches the entrance of the conveyor 19, if the entrance of the conveyor 19 is blocked by the article P or is closed by the entrance opening / closing stopper 27, the article P Cannot enter the conveyor 19 and accumulates.

However, by moving the blades 15 of the guide means, the article P moves in a direction transverse to the transport direction and is guided to another vacant entrance. As a result, the articles P are evenly supplied. In addition, the transport conveyor 19
The articles P not supplied to the chain 1 by the blades 15
Orbiting along 6 and back, it doesn't accumulate too much in front of the entrance.

The article P supplied to the conveyer 19 is conveyed, but the article P being conveyed is not oriented yet. Therefore, the article P contacts the rotating body 32 to change its direction, and the moving body 31 unifies the direction. At this time, since the rotating body 32 rotates counterclockwise, the article P is conveyed without being caught by the moving body 31. Therefore, after passing through here, the articles P are aligned and conveyed.

The articles P in the aligned state are sequentially sent from the conveyor 19 to the parallel conveyor 29, are conveyed by the parallel conveyor 29 and come into contact with the regulation stopper 41, and are restricted from moving further. At this time, the pushing plate 4
Even if 3 is on the parallel conveyer 29, the conveyed article P rotates in the direction B when it comes into contact with the conveyed article P, so that the conveyance of the article P is not hindered.

Until a predetermined number of articles P are lined up in each row on the parallel conveyor 29, the articles P are successively collected while maintaining the alignment.
After that, when a predetermined number of articles P are arranged in each row, the conveyors 19 corresponding to the arranged rows are stopped, the stoppers 27 and 28 are further raised, and the entrance and the exit of the conveyor 19 are closed. Therefore, new articles P are not conveyed from the rear of the aligned row, and the aligned state of the aligned row is not disturbed. And the parallel conveyor 29
When the number of articles P in each row above reaches a predetermined number, the regulation stopper 41
Is lowered to open the outlet of the parallel conveyor 29.

Then, the air cylinder 45 is driven to move the bracket 46 in the carrying direction, and as shown in FIG.
The article P on the parallel conveyor 29 is pushed out to the downstream side in the transport direction by the extrusion plate 43, and at the same time, the article P is brought to the center by the pulling rod 57. At this time, the pushing plate 43 is kept in the vertical state by being restricted in rotation by coming into contact with the abutting plate 53, and the product P is placed on the packaging conveyor 5 by moving the bracket 46 while making vertical contact with the product P. Extrude into. Further, in the pulling rod 57, the roller 60 rolls on the inclined surface 61a of the cam 61 by the movement of the bracket 46 and moves toward the center, thereby pulling the articles P on both sides inward.

As a result, as shown in FIG. 8, a predetermined number of aligned articles P are packed into the packing machine 1 while being tightly attached and sandwiched between the sheets 2 stretched up and down. Sent to. A group of articles P conveyed into the packaging machine 1 is packaged by welding the entire circumference of the sheet 2 in the packaging machine 1 to form a pack X.
This pack X is transferred to the stocker 7,
When a predetermined number of packs X are gathered in the stocker conveyor 8
Is carried to the next step.

When the article P is transferred to the packaging conveyor 5,
The restriction stopper 41 is raised to close the exit of the parallel conveyor 29, the stoppers 27 and 28 are lowered to open the entrance and exit of the transfer conveyor 19, and the transfer conveyor 19 is driven. Since the next aligned articles P are immediately lined up on the parallel conveyor 29, the waiting time until the next article P is pushed out can be shortened. Further, when the push-out plate 43 returns to the initial position, the push-out plate 43 comes into contact with the article P conveyed next to the parallel conveyor 29 but rotates in the B direction, so that the advancement of the article P is not hindered, and the push-out plate 43 is initially moved. Can return to position.

As described above, even if flat articles P are supplied in a disordered state, they are aligned and arranged, and a series of operations for aligning a predetermined number can be automatically performed, and they can be arranged efficiently without disturbing the aligned state. It is possible to achieve complete automation and unmanned operation without human labor.

Further, when the conveyors 19 in a row in which a predetermined number of articles P are gathered are stopped and the entrances and exits of the conveyors 19 are closed by the stoppers 27 and 28, the articles P are conveyed to the stopped conveyors 19. Is not supplied, the articles P on the transport conveyor 19 are not pushed by the articles P supplied from the rear, and the articles P do not overlap and the alignment state is not disturbed. Is obtained.

Further, the transport conveyor 19 is stopped, and the entrance and the exit of the transport conveyor 19 are both stoppers 27, 28.
The number of rows of the articles P to be aligned can be arbitrarily selected by closing the box by, so that it is possible to easily cope with a change in the number of the articles P in a group to be packed. Furthermore, the transport conveyor 19
With the moving bodies 31 provided on both sides of the article P, the articles P can be aligned by unifying and unifying the orientation of the articles P. Then, the rotating body 32 provided at the tip of the moving body 31 so as to come into contact with the article P can prevent the article P from being caught by the moving body 31 and can be transported smoothly.

If the supply means is provided with a guide means for moving the articles P in a direction transverse to the conveying direction, the articles P can be evenly supplied to the conveyer conveyor 19, and there is no variation in the time in which a predetermined number of the articles P are arranged in each row. Processing time for arranging is short.

Articles P arranged in a predetermined number on the parallel means
By providing an extruding means for pushing out and an aligning means for aligning the articles to be pushed out with each other, two operations such as aligning while pushing the articles P can be performed simultaneously, and the processing time for aligning the articles P can be shortened. You can

Further, when the push-out plate 43 is pushed out, the article P
Since the rotation direction is regulated so as not to hinder the progress of the article P when coming into contact with and returning to the article P, the next article P can be aligned while pushing out the article P without interfering with the progression of the article P to be arranged next. Then, the waiting time until the next predetermined number of lined articles P are pushed out becomes shorter.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, when the parallel conveyors 29 of the present embodiment are composed of a plurality of conveyors, a predetermined number of the conveyors are stopped to prevent an adverse effect such that an article frozen due to friction between the conveyor and the article is melted by frictional heat. .
