Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a compression type automatic packaging device, and more particularly, to a compression type automatic packaging device for a futon, a blanket, a cushion, etc., which requires compression packaging during packaging.

[0002]

[Prior art]

 Duvets, blankets, and cushions made of cotton, feathers, and synthetic fibers are required to be very elastic in terms of their functions, and are therefore very bulky in normal use. Such bulky futons are very uneconomical in transportation, and especially in transportation (talent) calculated by volume, cause a high cost. However, even if there is an advantage that the weight of each piece is light, the number of pieces will increase, and there is also a problem that it is troublesome to carry and carry during transportation. In addition, even if they are piled up in a warehouse before shipping, if they are bulky, more space is required, which also causes higher costs.

Therefore, in order to solve such inconvenience, it is usual to press a plurality of (5 to 10) futons into one package and print it into a package having an appropriate volume and weight. Usually, corrugated cardboard cases or paper bags (reinforced) are used for packing. However, in the case of corrugated ball cases, there is a drawback that the cost is 3 to 5 times higher than that of paper bags, so paper bags are often used. Is becoming.

In any case of packing, when the futon or the like is pushed in, if the volume is halved, the transportation cost will be significantly reduced. Therefore, it is preferable to compress multiple futons, etc., as much as possible, but this requires a great deal of force. In the old days, multiple futons were placed in a cardboard case or paper bag, and a few people from the top put their weight on them and pushed them in. However, if hundreds of packages were packed a day, it would be extremely labor intensive. Therefore, a device that performs compression mechanically (pressurized by an air cylinder) was developed.

This device is constructed such that a column is erected on a side portion of a pedestal on which a futon is placed, and an air cylinder moves up and down from the upper end of the pedestal toward the center of the pedestal. With the pressing plate, a plurality of futons contained in a paper bag (or a cardboard case) are pressed from above and compressed.

[0006] This device has an advantage that labor can be reduced and packing efficiency is greatly improved in that the futon can be mechanically compressed, but there is a problem in the work of closing the lid of the paper bag after the compression. That is, since the upper opening of the paper bag cannot be folded and closed while the piston rod of the air cylinder is pressing the duvet after compression, the piston rod is once raised and it takes a short time for the compressed futon to be restored. It took two or three people to close the upper opening of the paper bag all at once.

However, it takes only a short time for the compressed futon to be restored, and the futon is restored by the time the upper opening of the paper bag is closed, so that the folding operation of the opening of the paper bag cannot be performed smoothly. was there. Therefore, in order to solve these problems, in anticipation of the restoration time until the closing work can be loosened, the compression ratio is made larger (1/10) than the planned compression ratio, and the restoration time is increased, and the closing work is performed in the meantime. The method of (temporary fixing with adhesive tape) was adopted.

[0008]

[Problems to be solved by the device]

 According to this conventional packaging method and device, there is a problem that a large air cylinder with a high output for compressing the futon with a large stroke is required in advance, and even if such an air cylinder is used, it may not be possible in some cases. However, there was a problem that the futon was restored quickly and the work of closing the opening in the paper bag did not go smoothly. In order to avoid such a situation, as soon as the air cylinder starts to rise, it tries to close the paper bag immediately, resulting in a problem that the push plate at the lower end of the air cylinder is extremely dangerous.

[0009] Furthermore, even if the futon is pressed in a compressed state to close the opening of the paper bag, in order to temporarily stop the closure, someone presses the futon and another person uses the adhesive tape to hold the paper bag. There was also the problem that it was difficult to do the packaging work alone, because it had to be stopped.

The present invention solves the problems of the prior art, can mechanically fold and close the opening of the paper bag (or corrugated cardboard case), and requires labor for holding the futon in a compressed state. First, the purpose is to facilitate temporary fixing of the opening of the paper bag at the compression position. Other objects of the present invention will be apparent from the following description.

In order to achieve the above-mentioned object, the compression-type automatic packaging device according to the present invention places a paper bag having a closed bottom and an open top on a pedestal, and a plurality of compression-required compresses are placed in the paper bag. In a compression type automatic packaging device configured to store articles in a stacked manner and compress the article to be compressed from above by means of an upper compression means, a pair of side pressing means is provided on both sides of the pedestal, By the side pressing means, the two means of the upper opening of the paper bag are folded in the pressed state of the object to be compressed by the upper compressing means. It should be understood that the paper bag referred to in the device of the present invention includes a paper bag having strength in itself, or a paper bag reinforced with a synthetic resin sheet, and a cardboard case. In addition, the temporary fixing referred to in the present invention refers to something that is artificially performed using an adhesive tape or the like.

Further, the pressing portion of the upper compression means for compressing the object to be compressed is configured to be bent at the center position, and the tip portions of the pressing members of the pair of side pressing means are the upper compression means. It is preferable that the pressing portion of the means is configured to be overlapped with the pressing portion. Further, the pair of side portion pressing means includes a driving means for rotating each pressing member about a horizontal axis by a vertical arm, a driving means for vertically displacing the pressing member along a slide column, and And a driving means for rotating the pressing member around the horizontal axis at the upper end of the vertical arm, so that each pressing member of the pair of side pressing means moves in a substantially horizontal direction from the pressed state of the object to be compressed. It is preferably configured to escape to the side.

[0013]

[Action]

 According to the present invention, when packing an object to be compressed into a paper bag, the upper part is used to fold the upper part of the paper bag so as to cover the paper bag while temporarily compressing the object to be compressed by the upper compression means as in the conventional case. There is no inconvenience that the upper part of the paper bag must be pressed and folded without inserting hairs after the compressing means is released, and the upper compressing means presses the object to be compressed. Means can press the top of the paper bag so that it folds from both sides.

Therefore, it is sufficient to temporarily fix the two sides folded by the pair of side pressing means with adhesive tape or the like (gum tape) without manually pressing in this state. Then, when this temporary fixing is completed, the upper compression means rises, but at this time, the temporary fixing can maintain the compressed state to a predetermined bulk, and artificial pressure must be continuously applied. There is no inconvenience that it does not happen.

Further, since the pair of side pressing means presses the position pressed by the upper compression means, the restoration time (or expansion allowance) of the compressed object required for the folding work time of the paper bag as in the conventional case. It is not necessary to hold down with a large stroke in anticipation, and therefore the driving force of the upper compression means can be small.

【Example】

 A preferred embodiment of the compression type automatic packaging device of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a front view of an apparatus used in the compression type automatic packaging method, 1 is a pedestal on which the paper bag 11 (or a cardboard case) shown in FIG. 6 is placed, and 2 are provided on both sides thereof. It is a pair of slide columns. Each of the slide columns 2 is provided with a slide groove 2a. Reference numeral 2b is a side plate that guides the paper bag 11 and protects the paper bag 11 from a side-arranged mechanism described later.

Reference numeral 3 denotes an upper compression means, which is composed of an air cylinder 3d and has a stroke for compressing an object to be compressed (for example, a futon) to a predetermined bulk. This air cylinder is provided on a gate-shaped frame 3e (see FIG. 3) which is hung from a pedestal upright from the pedestal 1.

As shown in FIGS. 4 and 5, in the upper compression means 3, a pressing portion for compressing a substance to be compressed has a pair of arcuate arms 3b arranged to face each other, and at each of the facing portions, there is a rotation about each horizontal axis P3. It is configured to be switchable between a raised state in which it is rotatably folded downward and a pressing state in which the extended state is held by the urging means 3a. The biasing means 3a is configured to press the pressing plate with a coil spring here, and restrains the metal fitting 3c that holds the arcuate arm 3b.

Accordingly, if each tip end side of the arcuate arm 3b is gripped and rotated about each of the horizontal axes P3, the pressing plate is displaced upward against the coil spring, and the arcuate arm 3b is moved. Can be rotated downward as shown by the phantom line to fold, and conversely can be horizontally extended (opened). In FIG. 4, 3d indicates the air cylinder described above.

As shown in FIG. 1, reference numeral 4 denotes a pair of side portion pressing means arranged on both sides of the pedestal 1. The side pressing means 4 is configured as follows, respectively. Reference numeral 8 is an air cylinder as a driving means, one end of which is fixed to the above-mentioned slide column 2, and its rod side is attached to one end of an L-shaped support arm 5. A lower end of a vertical arm 6 is pivotally attached to the end portion of the support arm 5 so as to be swingable about a horizontal axis P1, and the pressing member 10 is provided at an upper end of the vertical arm 6 with the horizontal axis core. It is pivotally attached about P2 times. The supporting arm 5 is connected by the elongated hole 5a at the bent portion thereof, so that there is no play (movement allowance) during the pressing operation of the pressing member 10 and the backward movement in the substantially horizontal direction. Play a role.

Reference numeral 9 denotes a servomotor which slightly displaces the pressing member 10 around the horizontal axis P2. The servo motor may be replaced by connecting an air cylinder between a part of the pressing member 10 and the vertical arm 6. In FIG. 1, the imaginary line of the pressing member 10 indicates the posture at the pressing start position. Also, the imaginary line of the upper compression means 3 shows the pressed state and the folded and raised state.

The packing of the material to be compressed (futon, etc.) into the paper bag 11 by the above-mentioned device is performed in the following order. Futons carried by an appropriate means (conveyor or the like) are sequentially put into the paper bag 11 on the base 1 in the required number. Next, by operating the pedal (button), the upper compression means 3 is driven, and the futon is compressed to a predetermined bulk (height). In this state, the pair of side pressing means is driven by the operation of the pedal (button), the pressing member 10 is tilted, and the two sides of the upper opening of the paper bag 11 are folded.

In this state, the worker temporarily fixes the two sides folded by the adhesive tape. Next, the upper compression means 3 is driven and raised. At this time, a part of the upper compression means 3 is pressed by the side pressing means, but due to the pressing force, the upper compression means 3 is folded in two downwards and can be pulled out and moved upwards. This state is shown in FIG.

After the upper compression means 3 is raised, the operator manually folds the remaining two sides of the paper bag 11 and temporarily fixes the folded two sides with the adhesive tape. Next, a pair of side pressing means is driven by operating a pedal (button), and the pressing member 10 is pulled out laterally in a substantially horizontal direction. When the temporary fixing is completed in this way, the process is sent to the banding process.

In implementing the present invention, in order to change the stroke lower end position of the upper compression means 3 depending on the number of futons, the pedestal 1 may have a lift structure so as to raise the bottom. At this time, the pair of side pressing means 4 can change the position of the pressing member 10 by the air cylinder 8. It is of structure.

[0027]

[Effect of device]

 According to the present invention, when the upper compression means presses the object to be compressed and the pair of side pressure means presses the upper part of the paper bag so as to fold it from both sides, temporary fixing work can be performed, and the bag This makes packing work extremely easy, and eliminates the need for a few people to grapple as they used to.

Then, since the pair of side pressing means presses the position pressed by the upper compression means, the restoration time (or the compression time of the compressed object required for the folding work time of the paper bag as in the past) (or There is no need to hold down with a large stroke in anticipation of the expansion margin), so there is an advantage that the driving force of the upper compression means can be small.
