Abstract

PURPOSE:To improve the efficiency of handling by inserting L-shaped chuck members between flaps of cartons in a packing box, thereby moving the cartons with both ends of the cartons being held by presser members when small carton packaging cartons folded and housed in a packing box are automatically supplied. CONSTITUTION:Folding cartons 3 having short flaps 7 above and long flaps 8 below are housed in a packing box 11 so that each row of cartons is in contact with each other. Clutch members 41 consisting of two holding plates bent into L-shape are inserted into gaps 4 between short and long flaps 7, 8 from both sides of the row cartons. Spacers 12, 13 are then inserted between the packing box 11 and the row 5 of cartons to form gaps 18 capable of accommodating end parts 41a of chuck members 41 and presser members 44. The presser members 44 are inserted into the gaps 18 to allow the cartons to be transported with the row of cartons held from both ends.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a cartoning machine that packs small packaging cartons that are folded and stacked in at least one line and stored in a packaging box. This relates to a method for efficiently handling and loading.

[Conventional technology]

As shown in FIGS. 15 and 16, conventionally, the small packaging carton 3 has been folded into a flat shape, for example,
250 items 5 are stacked in one row, arranged in 4 rows and 2 tiers, packed in a packaging box, transported to a cartoning machine, unpacked, and packed one row at a time. The cartons were removed and manually loaded into the feed section of the packaging machine.

The packaging machine feeds folded cartons one by one in correspondence with the items to be packaged, and opens and raises the cartons into a cylindrical shape so that the items to be packaged can be easily inserted.After inserting the items to be packaged, the flaps of the cartons are opened. After sealing and gluing, etc., the individual packaging was completed, and either the products were collected as they were, or they were collected into a plurality of predetermined units and used for integrated packaging such as wrapping.

[Problem to be solved by the invention]

A person must be present to unpack and load the cartons into the packaging machine. In particular, with recent high-speed packaging machines, it is necessary to feed stacked cartons in units of fiber separation, and even if a person were to feed and load them, it would take a lot of effort, and one person would not be enough. Become.

Therefore, if the packaging of the carton stacking packaging box 2 is opened and the case is placed in a predetermined place, the handling device can grab the stacked cartons one row at a time and transport them to the cartoning and packaging machine. This eliminates the need for dedicated personnel.

Although it is possible to use a dedicated container for this purpose, it is large in size and weight, and is difficult to handle in terms of workability. Furthermore, the carton making factory and the packaging factory where the cartoning and packaging machines are installed are generally far apart in terms of distance, and if a fixed-shaped container is used to shuttle between the two, only empty boxes will be returned on the return trip. It is like carrying air and is unproductive for transportation.

Due to the ratio, it is possible to use an assembly type container, but this increases the weight, complicates the shape, makes handling and operability difficult, and increases costs.

The present invention solves the above-mentioned problems and provides a method for automatically feeding cartons to a cartoning and packaging machine more reliably, inexpensively, and efficiently using disposable packaging boxes packed with stacked cartons. The purpose is to provide.

[Means to solve the problem]

The purpose of this is (1) to insert at least one leading edge into the gap between the flaps provided on both sides of a plurality of cartons that are folded into a flat shape, stacked in at least one row in one direction, and stored in a packaging box. A chuck member consisting of two gripping plates bent into an L-shape is inserted to grip the carton from both sides, and a chuck member is placed at both ends of the carton in the stacking direction in the center of the stacking direction. A carton pressing member is provided which can be pressed toward the carton and the interval can be adjusted in accordance with the amount of stacking, and a spacer for guiding the insertion of the pressing member is provided inside the packaging box to grasp and lift the stacked cartons into a predetermined position. An automatic carton supply method characterized in that the cartons are conveyed and supplied; or (2) on both sides of a plurality of cartons folded into a flat shape and stacked in at least one row in one direction and stored in a packaging box. Insert the intermediate sides of two bent rod-shaped members bent in a U-shape into a structure in which both end pieces are connected to a movable piece into the provided flap gap to grasp the carton from both sides, and grasp the carton from both ends in the stacking direction. a carton pressing member which can be pressed toward the center in the stacking direction and whose spacing can be adjusted in accordance with the amount of stacking; furthermore, a spacer for guiding the insertion of the pressing member is provided inside the packaging box;
This is achieved by an automatic carton supply method characterized in that the stacked cartons are picked up and conveyed to a predetermined position for supply.

〔Example〕

An example using the method of the present invention will be described using FIGS. 1-14. However, the present invention is not limited to these embodiments.

First, as shown in Fig. 1, 200 to 250 sheets of folding cartons 3 are arranged in one direction with short flaps 7 on top and long side flaps 8 on bottom, and the folding cartons 3 are arranged in a row with each other. A plurality of rows are arranged in one row on at least the same plane and placed in a packaging box 11 with the rows in contact with each other,
In order to grasp the aligned cartons from both sides one by one, a handling chuck member is installed between the short flaps 7 of each row or between the inner wall of the packaging box and the short flaps 7 of the end row.
I'm putting it in. Then, the folded end of the chuck member is inserted from both sides into the recess formed by the gap 4 between the short and long flaps at the top and bottom of the carton, and one row of the stacked and aligned cartons is sandwiched from both sides. It is necessary to make sure to grasp it.

At the same time, it is necessary to ensure that all cartons near both ends of each row are grabbed and lifted up without being left behind. For this purpose, it is necessary to apply pressing members to both ends of the row of cartons so that they are brought to the center in the alignment direction, so that the entire row of cartons is sufficiently held by the chuck member.

Further, for this reason, it is desirable that the chuck member be as long as possible. To do this, carton packaging box 1
A spacer I3 is required on the inner side in the carton alignment direction of No. 1 to create a gap 18 into which the suppressing member 44 fits and a gap 17 into which both ends 41a and 41b of the chuck member 41 fit. Alternatively, by pressing the pressing member sufficiently to the center in advance without using such a spacer, the gap 17 caused by the spacer can be reduced.
It becomes possible to reliably chuck without removing it.

As a spacer, one spacer 12 bent into a U-shape as shown in FIG. 2 may be used for each of the lower and upper stages, but as shown in FIG.
may be placed on the upper stage and spacers 3 as shown in FIG.

Also, instead of using the U-shaped spacer 12 shown in Fig. 2, the spacer 13 shown in Fig. 3 was used, and after the cartons were packed in the lower tier, the partition plate 14 was placed on top of the lower carton and used for the upper tier. The same spacer 13 may be used. Spacer 1
3 may be glued to the inside of the packaging box 11, or may simply be inserted between the carton 3 at the end of the carton row 5 and the inside of the packaging box 11.

Alternatively, as shown in FIG. 5, a spacer I6 may be attached to the inside of the packaging box II to create gaps 17 and 18. At that time, it is necessary to place a partition plate 14 at the boundary between the upper and lower stages.

Alternatively, without providing a spacer, perforations 25 are provided at both ends of the carton packaging box 11 in the carton alignment direction as shown in FIG. Before the pressing member 44 is positioned at the end of the carton and presses the end, for example, as shown in FIG. A suppression bar 46 provided with a roller 47 is abutted against the perforation, and the eighth ffl
As shown in (a), a casement window 27 is formed and the inner row of cartons is pressed from the end to create a gap between them and the inner surface of the carton packaging box 11, and the pressing member 44 is inserted into the gap, and then the carton row is pressed from the end. In this method, the ends of the rows are pressed toward the center of the row, and chuck members 41 are inserted into the recesses 4 in the gaps between the flags from both sides so that the rows of aligned cartons can be reliably gripped without falling out.

This casement window 27 may be perforated as shown in FIG. 8(a), or may have a round hole 28 or an elongated hole 29 from the beginning as shown in FIG. 8(b). .

However, the former is more desirable from the standpoint of complete dust-proof packaging.

Alternatively, as shown in FIG. 6, a spacer 19 formed by cutting both ends of a strip of cardboard approximately along the center line and bending the ends alternately at right angles may be used. In this case, the bent end may be attached to the inner surface of the packaging box 11 if it is stacked in one layer, but
In the case of stacking, it is better to just drop the top shelf down.

In this case, most of the strips between the carton rows serve as partition walls between the carton rows.

In addition, as a measure to create a space effect, as shown in Figure 7, perforations are alternately made on the front and back sides of the surface where both end surfaces of the carton packaging box meet in the carton alignment direction, creating unevenness toward the front or back. This makes it possible to create a space effect.

In addition, in the present invention, the short side of the carton flap is placed at the top and the long side is placed at the bottom, and by tightly packing 200 to 250 pieces in the stacking direction in the carton packaging box, the long flaps are in contact with each other. Even if the cartons are packed roughly, if a very thin partition plate is inserted between the flaps, the cartons in each row will remain in the correct row and will not mix or be disturbed. In addition, the long flaps on one side of the carton rows in the end rows of the carton packaging boxes are designed to come into contact with the inner surface of the packaging box, so the volume of the carton packaging box as a whole is the minimum necessary volume. It is now possible to store it in The aforementioned chuck member can easily fit into the gap between the short flaps, and when the carton is turned upside down, a thick large partition spacer is used to create a gap between the long flaps. It is not preferable to provide the same number of columns as the number of columns, which increases the volume, complicates the shape, and increases the weight.

Therefore, it can be said that the carton packaging box using the method of the present invention is very efficient.

The tip of the chuck member 41 is bent into an L-shape, and the chuck member 41 is inserted into the recess between the long and short flaps from both sides.
The chuck member may be gripped as shown in FIG. 13(a), or one side of the chuck member may be gripped as a flat chuck member 41b as shown in FIG. 13(b). The present applicant has confirmed that either method can be used to securely grip the chuck member, and a U-shaped bent rod member 42 as shown in the perspective view of FIG. 9 may also be used as the chuck member. However, it is desirable that the vertical gaps 4 between the long and short flaps have a considerably large shape.

So far, I have talked about the main body of the carton packaging box, but once the carton is loaded and stored in the packaging box, you can either cover the lid and seal the seam, or simply cover it with a sheet of paper or plastic and seal it. This often prevents damage or deterioration of important packaging materials during transportation.

Alternatively, a packaging box may be formed in which one side of the lid is joined to the main body so as to share one ridgeline of the box main body, and the lid can be opened and closed using the ridgeline as a pivot. However, in this case, it is necessary to devise a method to prevent the lid from returning after opening, so that the handling of the rows of cartons is not hindered.

When the carton is to be fed to the packaging machine after transportation, the seal may be broken, the packaging box 11 containing the carton, placed in a predetermined position, and handled.

Now, as a handling method, as shown in the perspective view of FIG. 14, the pressing member 44 is pressed in the direction in which the cartons are aligned, that is, in the Y direction. For example, when handling a small number of cartons, such as packaging less than 1000 pieces of special packaging film, it is possible to easily adjust the length between the pair of pressing members in the Y direction. . In addition, when a spacer is not used in the packaging box, the pressing bar 4 corresponding to the casement window 27, round hole 28, long hole 29, etc.
6 presses the end of the row of cartons, and the pressing member receives the end of the row of cartons so that the pressing bar returns to its original position while further pressing the row of cartons. That is, the push bar 46 is designed to be incorporated into the handling device so as to operate in the Y direction.

Further, in the gripping direction X, the chuck member 41 is configured to be able to move to grip the rows of cartons.

In addition, the carton rows can be lifted up and down in the Z direction. Furthermore, if this handling device is configured to be rotatable around the Z axis, it will be convenient for positioning after transportation.

In this way, the method of the present invention can be incorporated into a handling device such as a robot to pick up the cartons one by one from the carton packaging box placement position and reliably transport and supply them to the carton loading position for packaging. It is clear that it is easy to implement.

〔Effect of the invention〕

According to the present invention, it is possible to reliably and stably supply cartons to a high-speed cartoning machine by placing the cartons in a predetermined position and unpacking them without using a large-capacity container with a complicated shape. This makes it possible to completely eliminate the need for carton supply staff even when operating high-speed machines, making it possible to greatly contribute to improving the efficiency of the packaging process.

Also, since there is no need to use a special returnable container, it can greatly contribute to improving transportation productivity and reducing production and packaging costs.
