Description

Detailed Description of the Invention (Industrial Application Field) The present invention adds a series of functions to a compression packaging device, and is designed to prevent cigarette filter tow and sanitary wire rings from being contaminated by foreign matter, contamination, and binding bands being dug into them. The present invention relates to a compression packaging method for continuously and automatically packaging items.

(Prior art) When packaging compressed products such as synthetic fibers and natural fibers, which have a low bulk density and a large repulsive force, the repulsive force after compressed packaging may cause the binding band to dig into the packaging, and the wrapping during transportation or handling. In order to prevent contamination of the packaged items and contamination of foreign substances due to material damage, we have traditionally used bonded or laminated sheets of polypropylene Heshan cloth and polyethylene sheets, as well as kraft paper lined with polyethylene film, etc. The conventional method was to wrap the items in a box, protect the outside with a reinforcing material that has excellent rigidity and strength, such as a cardboard sheet or a plastic sheet, and then tie it with bands or wire. Traditionally, this was performed manually.

Conventionally, when packing items such as cigarette filter tow (synthetic fibers) and sanitary cotton, which have a low bulk density and avoid contamination with foreign substances and dirt, the items to be packed must be left open on the top and bottom.
After compression molding is carried out from one direction each up and down or both directions inside a compression box for molding whose sides can be opened and closed, the four sides of the compression box are opened, and the upper part is attached to the upper and lower press seats of the compressor by hand in advance. and the lower reinforcing material, or the upper and lower packaging materials that are located between the reinforcing material and the object to be packed, and are used to directly wrap the object.
There is a method of manufacturing packing bales by manually applying reinforcing material consisting of 2 to 4 pieces to the sides to reinforce this surface, then tying the bales manually using several binding bands, and then releasing the compressive force. It had been taken.

An example of a conventional compression packing method will be explained below with reference to FIGS. 10 and 11, taking a tow packing method using acetate for cigarette filters as an example. FIG. 10 is a front view of a conventional compression packing machine, and FIG. 11 shows the AA cross section in FIG. 10. Furthermore, Fig. 1 shows an overview of a series of packing operations using this type of compression packing machine, including manual wrapping, attaching reinforcing materials, and bundling (Please note that Fig. 1 is necessary for explaining the present invention. Therefore, only the necessary parts to explain the manual method have been extracted).

In the previous process, the objects to be packed, such as acetate tow, are stored in the enclosure box 1 shown in FIG. 10, and then transferred to the center of the compression packing machine as shown in FIG. It is carried in and further positioned by the positioning device 2.

On the other hand, reinforcing materials 5a, 5 such as cardboard sheets, kraft paper, or even plastic sheets are manually inserted into the upper press seat 3 and lower press seat 4 of the compression packing machine, as will be described later.
b is a flexible packaging material 6a, 6b such as a polypropylene heshan cloth and a polyethylene sheet pasted together or laminated together with clasps 7a, 7b.
It is installed by. In addition, when the enclosure box 1 reaches the center of the compression packing machine, the upper press seat 3 is covered with the reinforcing material 5a.

It is at the upper limit (as shown) position together with the packaging material 6a. Further, the lower press seat 4 is located near the upper end level (ascent limit) of the fixed frame 8 together with the reinforcing material 5b and the packaging material 6b, and the large doors 10a, 10b and small door 11 in the compression box assembly 9 are in a closed state. . In addition, the large doors 10a and 10b in FIG.
The illustrated state indicated by the two-dot chain line indicates the open state.

Now, in the above-mentioned state of each part, the enclosure box L is first lowered to the neutral position 13 by the enclosure lifting device 12 attached to the compression packing machine, and then the tow receiver of the enclosure box L is moved by the enclosure box bottom tow receiver opening/closing device (not shown). 14 is opened and continues to descend to a position where it overlaps the upper end of the fixed frame 8 (lowering limit). Further, the lower press seat 4 is connected to the enclosure box 1 via a reinforcing material 5b and a packaging material 6b.
It is lowered by a hydraulic cylinder 16 or the like while supporting the inner tow 15, and reaches a lowering limit 17. For this reason, the tow 15, which is the object to be packed in the enclosure box 1, is transferred to the compression box 9, leaving a part of it inside the enclosure box 1.

On the other hand, the upper press seat 3 is lowered by a hydraulic cylinder 18 or the like together with the reinforcing material 5a and the packaging material 6a, and the enclosing box l
Then, the tow 15 in the compression box 9 is compressed and shaped into the compression box 9 to a predetermined height with a predetermined compression force.

Next, at the compression height of the upper press seat 3, the compression box 9
The large doors 10a, 10b and small door 11 are opened manually or automatically. Thereafter, the work of wrapping the tow with the packaging material, attaching the reinforcing material, and tying the tow is performed manually.

The series of manual packing operations described above will be explained below based on FIG. 1. When the compression packing machine completes compression molding of the tow 15, which is the object to be packed, in the compression box 9 to a predetermined compression force and a predetermined height and the large doors 10a, 10b and small door 11 are opened, the tow mass is compressed. In this state (hereinafter, this state is maintained when the wrapping and binding work is completed), the tow is manually wrapped using the packaging material 6b as shown in (b).

Next, the vicinity of the upper end of the lower packaging material 6b is wrapped,
As shown in (C), packaging using the upper packaging material 6a is performed manually. Upper and lower packaging materials 6a.

The threading of 0 and the joining process of both end faces are performed. At this time, since the binding band 20 such as a band (or wire) is loose with respect to the tow mass (upper and lower packaging materials), use this gap to insert it like a side reinforcing material 19a and 19b. be done. And then (as shown in the barrel, mirror reinforcement material 21
a and 21b are assigned manually.

Next, the upper press seat 3 and the first press seat in FIG. 10(b)
In Figure 0(C), the band (or wire) is passed through manually by using the through grooves (not shown) that are perpendicular to the band (or wire) through grooves 3a and 4a attached to the lower press seat 4, and the both ends of the band (or wire) are passed through. Surface merging processing is performed.

Next, the tow mass is released from the compressed state (the upper press seat 3 is raised) and expands to the state where it is restrained by the band (or wire). Thereafter, both ends of the side reinforcing members 19a and 19b are manually processed (bent) as shown in (h), and then bound with bands 22 to complete a compressed bale. Next, when the bales are taken out of the compression packing machine manually or by a bale removal device (not shown), the first
As shown in Figure 0 (b) and (C), the reinforcing material 5b and the packaging material 6b
is attached manually and fixed to the lower press seat 4 by a stopper 7b.

Subsequently, by operating a push button (not shown), hydraulic cylinder 1
8 is operated, the ram is lowered, and the upper press seat 3 is lowered to a level convenient for attaching the upper reinforcing member 5a and the upper packaging material 6a, and then stopped. At this level of the upper press seat 3, the reinforcing material 5 is manually added to the upper press seat 3 in the same manner as described above.
a and the packaging material 6a are attached and fixed by a stopper 7a.

After the above manual operations are completed, by operating a push button (not shown), the upper press seat 3 is pulled up by the hydraulic cylinder 18 together with the reinforcing material 5a and the packaging material 6a, as shown in FIG.
) returns to the state shown. On the other hand, the bottom toe receiver 14 of the empty enclosure box 1 is closed, the enclosure box 1 is raised to the upper limit level by the lifting device W12, and the positioning device is opened.
The enclosure box 1 is transported to the outside of the compression packing machine by a transport device (not shown), and one cycle is completed.

(Problem to be Solved by the Invention) However, in this type of conventional packaging method, in order to shorten the cycle time and reduce the labor of the operator, the reinforcing materials 5a and 5b and the packaging materials 6a and 6b are set in advance by 1 m each. It is necessary to assemble them in advance and fold them for convenient work, which has the drawback of requiring manpower and storage space for this work. Also, apart from attaching the reinforcing material 5b and packaging material 6b to the lower press seat 4, attaching the reinforcing material 5a and packaging material 6a to the upper press seat 3 requires upward work.
Moreover, since the weight of these items reached several kilograms, the work required a considerable amount of effort and the workers felt very fatigued.

Furthermore, the binding materials such as bands and wires must be cut to a predetermined length and stored in advance, and the packaging, installation of the side reinforcing members 19a and 19b, and the binding work are manual labor, making it difficult for workers to do so. It has the drawback of requiring effort, and
Two to four workers were required, depending on experience. For this reason, there is a high risk of personal injury due to human operating errors or work errors, and in any case, the above work is highly dangerous because it involves work around a press machine that weighs tens to hundreds of tons. In addition, there were drawbacks such as the packaging style being dependent on the experience of the operator.

The present invention has been proposed to solve the above-mentioned conventional problems.

(Means and effects for solving the problem) Therefore, the present invention compresses a bulky tow-shaped object to be packed into a cube or rectangular parallelepiped shape, and then uses a flexible packaging material to compress the upper and lower parts. It is automatically wrapped using a packaging device, and then reinforcement is automatically applied to all the outer surfaces using a reinforcing material lifting device, a reinforcing material lifting device, a reinforcing material supply trolley, etc., and the outer surfaces are bound with a binding band. This is how it happens,
This is a means and action for solving problems.

(Example) The present invention will be described below with reference to the embodiments shown in the drawings. Figures 1 to 9 show examples of the present invention, and Figure 1 shows a series of flows of packing operations according to the present invention. , as mentioned above
FIG. 2 shows an overview of the timing and system for supplying packaging materials, reinforcing materials, and binding materials to the main equipment in carrying out the packing operation according to the present invention.

Now, the present invention deals with compressed packaging bales, especially packaging bales of acetate tow for cigarette filters, etc., where from a sanitary standpoint, there is a problem of contamination by foreign matter from the outside due to breakage of the packaging material, and furthermore, was proposed to solve the problem caused by the binding band biting into the packaging material and tow due to the repulsive force of the tow, which is the object to be packaged. In order to prevent tow entanglement and tangles that occur in advance, the tow to be packaged is compression molded to a predetermined height, and then polypropylene heshan cloth and polyethylene sheet are bonded or laminated. After packaging with a flexible packaging material such as a polyethylene sheet and kraft paper laminated together, the entire outer surface is covered with a so-called reinforcing material that is stronger and more rigid than the packaging material, such as a cardboard sheet, plastic sheet, or kraft paper. This relates to a method for completely automating a series of operations for binding with bands, wires, etc.
