Description

[Detailed Description of the Invention] The present invention reduces the size of industrial cotton such as rock wool, asbestos, and glass wool, as well as noble items such as bedclothes such as futons, and packs them into a bag.
The present invention also relates to an apparatus for manufacturing a sealed package for sealing a bag.

Since the sealed package obtained by such a manufacturing apparatus has a low volume, it can be stored and transported by stacking economically.

By the way, the biggest problem when producing sealed packages mechanically and automatically is how smoothly and reliably the reduced packaged items can be stuffed into the original fabric (bag). . This is because the cylindrical original fabric is rolled up in a pre-squeezed state, and when the original fabric is pulled out and the reduced packaged items are stuffed into it, the original fabric is fully compressed. If it is not expanded or the shape of the expanded original fabric cannot be maintained,
This means that you will not be able to do that stuffing properly.

The object of the present invention is to automatically expand the original fabric into a shape that makes it easy to pack the reduced packaged items in the drawer, and to seal the original fabric so that the packaged items can be packed while maintaining the expanded shape. The object of the present invention is to provide a packaging manufacturing apparatus.

A core that can skillfully spread the original fabric and be located within the original fabric, and a positioning device for this core are provided.

According to the present invention having such a structure, the material to be pulled out can automatically expand the reduced packaging material by the core, and the bag can be formed while maintaining the expanded state of the material. Since the bag is fitted onto the guide body, the extruded object to be packaged can be reliably stuffed into the bag. Therefore, stuffing of the packaged items into the bag can be done mechanically and automatically.

The action will be explained below.

First, the press deaeration effect of the press type deaerator 1 will be explained based on FIGS. 1 to 3. Figures 1 and 3
As shown by the solid line in the figure, the swinging side wall 14 is opened with the press plate 6 raised, and the packaged object 12 is thrown into the four side wall bodies 3 through the charging hopper 16 and the charging opening 13. At this time, shutter 19
The take-out port 18 is closed by the push-out body 22, and the passage port 17 is closed by the extrusion body 22. Next, with the swing side wall 14 closed, the press plate 6 is lowered to compress the packaged object 12 between it and the bottom plate 4. At this time, a suction force is exerted by the suction duct 11 into the four side walls 3 through the suction port 10, thereby promoting degassing of the packaged object 12. As shown by the imaginary line in FIG. 3, the shutter 19 is opened with the object to be packaged 12 sufficiently reduced in size, and the extrusion device 21 is operated. As a result, the pushing body 22 moving forward pushes the object 12 to be packaged, and the object 12 to be packaged is pushed into the guide body 26 through the outlet 18 .

At this time, the bag body 58 is already fitted onto the guide body 26. In other words, the roll-shaped raw fabric 27
The operation by the drawer device 29 and the bag supply device 6
The core 3 is pulled out by a tensile force of 0, and the core 3
Pass through part 2. At this time, as shown in FIGS. 4 to 6, the original fabric 27 is guided by the front guide rod 36 of the core 32 and is gradually expanded in the vertical direction.
Then, it is finally expanded into a horizontally long rectangular shape by the rear guide body 40. At this time, the core 32 is positioned by the positioning device 51 so as not to move forward or backward, and furthermore, the fit between the annular protrusions 49 and 50 and the annular grooves 56 and 57 prevents it from shifting laterally. has been done. In this way, the original fabric 27 is automatically expanded by the core 32 located within the original fabric 27. Bag body 5 in the previous process
As shown in FIG. 7, the original fabric 27 having the number 8 formed thereon has its front end slightly protruding forward from the core 32. In this state, as shown by the imaginary line, the movable body 66, which is formed by swinging the swing plates 74 and 75 so that their tips come into contact with each other, is moved forward the most, causing its tips to plunge into the web 27. Next, the cylinder device 82,
83 closes the clamping plates 80, 81, and the original fabric 2 is moved between the clamping plates 80, 81 and the rocking plates 74, 75.
Hold 7. That is, as shown in FIG. 17, it is clamped at four locations as indicated by clamping points a. The movable body 66 is moved backward in this sandwiched state, and at that time, the cam rollers 78 and 79 move against the cam rails 76 and 7.
7, both rocking plates 74 and 75 are rocked apart from each other, and as a result, as shown in FIG. . The movable body 66 is the guide body 2
When it reaches near the tip of 6, it is stopped for a moment, which means that it has been pulled out by a predetermined distance. In this state, the original fabric 27 is sealed and cut by the seal-and-cut device 59, and the bag 58 held by the bag supply device 60 is formed. The seal and cut is the rear guide body 4.
0, and at that time the rear guide body 40
is deformed in the vertical direction against the elastic force. However, after cutting, the opening moves due to elastic force, and an opening is again formed at the tip of the original fabric 27 as shown in FIG. After forming the bag body 58, the movable body 66 moves again, and thereby the guide body 2
A bag body 58 is fitted onto the outside of the bag 6. The clamp is released after external fitting. In this state, the object to be packaged 12 is pushed out from the guide body 26 as described above. Therefore, the object to be packaged 12 is inserted into the bag 58, and the resulting open package 88 is placed on the slide table 91.

At this time, the slide table 91 has moved toward the guide body 26, and after supporting the open package 88, moves away from the guide body 26. As a result, the opening edge 58a of the bag body 58 is completely removed from the guide body 26. Next, the feeder device 96 is operated, and the opening package 8 is opened by the locking movement of the locking plate 99.
8 is transferred laterally and transferred onto a belt conveyor device 94 via a guide plate 93, and then transferred to a stopper 10.
0 and is positioned.

At this time, the opening device 134 has its suction tubes 146 and 147 moving forward and separating from each other, as shown by the imaginary line in FIG. Rim 58a
Both suction tubes 14 hang down as shown in A.
It is inserted between 6,147. Then both suction tubes 14
6,147 is moved backward while applying a suction action. At this time, both the suction tubes 146 and 147 gradually move toward each other and perform parallel movements, during which both sides of the opening edge 58a are sucked to form an enlarged opening as shown in (B). The upper suction tube 146 requires a large suction force, and therefore there is a risk that the opening edge 58a may be squeezed into the suction port 155, but this is prevented by the mesh 156.

The opening closing device 101 is operated with the opening edge 58a opened in this manner. That is, the operation of the cylinder device 107 first causes the suction nozzle 108 to
advances, and the front stop 1 of the actuating member 115
17 causes the lever 113 to move forward. As a result, the suction nozzle 108 and the lever 113 are connected to the opening edge 58 as shown in the imaginary line in FIG.
Push it into a. Next, with the suction expansion action by the expansion device 134 released, the cylinder device 1 is opened.
14 causes the lever 113 to swing apart,
As shown in FIG. 20, the opening edge 58a is stretched flat without wrinkles. Then, both the cylinder devices 124 and 128 in the sealing device 103 are activated in the first stage, and the opening edge 58a is sandwiched from above and below by the sponge rubber body 131 and the rubber body 133, which are approaching each other. At this time, the suction nozzle 108 and the lever 113 are also clamped, but the stepped portion that occurs at this time is absorbed by the deformation of both the rubber bodies 131 and 133.
The opening edge 58a is thus sealed. In this state, suction is applied, and the inside is degassed via the suction nozzle 108. At that time, even if the nozzle port 119 is spaced apart from the end surface of the packaged object 12, the opening edge 58a to be sucked is not further sucked by the coil 120, that is, it is not inserted into the nozzle port 119. Since the suction path 121 is secured, the desired degassing is accomplished. Furthermore, even if the nozzle port 119 comes into strong contact with the end face, the coil 120 pushes into this end face, so the suction path 121 is not blocked, and the desired degassing is similarly accomplished.

After degassing, the cylinder device 107 is moved to contract. As a result, the suction nozzle 108 is first moved out (retracted), but at that time, the lever 113
Since the opening edge 58a remains, it is possible to prevent wrinkles from forming on the opening edge 58a due to friction during extraction.
When the suction nozzle 108 is pulled out, the actuating member 115 is locked with the rear locking body 118, and the lever 113 is pulled out. After the suction nozzle 115 and lever 113 are removed,
Both cylinder devices 124 and 128 are operated in the second stage, and the opening edge 58a is sealed by the heat bar 125 and the mat 129, thereby obtaining a sealed package. This sealed package is transferred to the idle roller conveyor device 9 by the operation of the belt conveyor device 94.
It is carried out to the 5th side.

21 and 22 show a ball 1 as a contact member.
