Description

[Detailed description of the invention] This invention is a packaging bag made of paper, plastic, aluminum foil, or a combination of these, especially a standing bag (hereinafter simply referred to as a bag) that has self-reliance and retention properties when inflated. In a series of high-speed automatic bag filling and sealing lines that fill the bag with objects and hermetically seal the filling port of the bag filled with the contents, the bag is inflated following the opening of the top filling port and is fed from above. It pertains to a bag supporting stand that stores and holds the bag vertically, takes out the full bag after the filling and sealing is completed, separates it, and then returns it to the bag. A bag that can be applied to a rotary set high-speed liquid filling machine even for soft containers made of soft materials, such as bags made of foil or a composite thereof, compared to containers made of hard materials such as metal or glass. Regarding the support stand.

A rotary set high-speed liquid filling machine is often used as a filling machine that continuously fills liquid contents into individual containers at high speed, but its structure is designed exclusively for hard containers such as cans and bottles. The filling nozzle mechanism, which has been pushed up by the pressure contact of the filling opening at the upper end of the hard container raised by the lift mechanism with the nozzle opening of the filling nozzle mechanism, is opened, and the contents are filled into the hard container from the nozzle opening to a predetermined amount of content. After filling, the rigid container is lowered by the lowering operation of the lift mechanism, and when the nozzle opening and the filling nozzle mechanism, whose upper end filling opening portion is in pressure contact, are lowered together, the filling nozzle mechanism is closed. .

On the other hand, an attempt is made to apply a conventional bag supporting stand of this kind that vertically holds an inflated and loaded bag with its upper end filling opening opened and the bag supporting stand to the rotary set high-speed liquid filling machine. Then, in order to ensure the workability of sealing the top end filling port and separating the drawer from the bag support in the subsequent process, if the bag is made of soft material and the upper part is not supported at all, the top end filling port is not supported like the above-mentioned hard container. The method in which the opening is pressed against the nozzle opening and the filling nozzle mechanism is pushed up opens the filling nozzle mechanism and the contents flow down to fill the bag, which could not be applied because the bag would be bent, which was a bottleneck in increasing speed. .

The present invention aims to solve the problems of the conventional bag support and provide a bag support that can be applied to a rotary high-speed liquid filling machine.

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The bag support base A of the present invention has both seam edges α1, . A pair of left and right bag holding columns 5 and 6 each having vertically provided insertion grooves 3 and 4 for inserting and holding α2 are arranged in parallel to each other on the left and right sides in the cylindrical board 7, and the insertion grooves 3,
A holding hole 10 having grooves 8.9 on both left and right sides that match 4 and having a shape that almost matches the cross-sectional contour of the body of the inflated bag α.

The push-up plate 11 is a rotary set high-speed liquid filling machine 12.
The elastic body 16 of the filling nozzle cover 15 is attached to the lower end of the filling nozzle mechanism 13 of the bag α, and has a funnel-shaped nozzle opening 14, into which the upper end filling opening α3 of the bag α can be freely fitted, hanging from the center of the top.
It is formed in such a size that it can freely come into contact with the lower end opening edge 17 to which the left and right bag holding columns 5 and 6 are attached, and the upper ends of the left and right bag holding columns 5 and 6 straddle each other.
Screws 19 are screwed into female screw fittings 18 screwed and embedded in the tops of the left and right bag holding columns 5 and 6 at both left and right end portions of the push-up plate 11 which is superimposed on each upper end of the left and right bag holding columns 5 and 6. The head is fixed by sinking screws so that the head surface presents a flat surface that does not protrude above the upper surface of the push-up plate 11.

The cylindrical disk 7 has the left and right bag holding columns 5 and 6 arranged side by side as described above, while reinforcing the front and rear wall portions 21 and 22 of the peripheral wall 20 of the cylindrical disk 7 where the left and right bag holding columns 5 and 6 do not exist. At the same time, when pulling out and separating the full bag α, which is able to guide the lower part of the bag α and prevent it from swelling more than a certain level after filling with the contents, that is, the bag α is sealed tightly with the contents filling liquid, from the bag support base A, the drawer separation is performed. It is held by vibration etc. while being transferred to the separation station where it is carried out (the lower part of the full bag α, which has swollen to a size of 110, is caught on the push-up plate 11 that penetrates the holding hole 10, and the full bag α is automatically pulled out and separated. In order to prevent problems from occurring, the retaining protrusions 23 and 24 are shaped diagonally downward inward from the upper ends of the front and rear walls 21 and 22, and both left and right sides are formed with rounded concave surfaces and are provided oppositely. On the other hand, there is a drain hole 26 in the center of the bottom plate part 25 for draining the contents that drips into the bag support A.
It is made by penetrating it.

Since the bag support base A of the present invention is constructed as described above, its application to a high-speed automatic bag filling and sealing line will be explained with reference to FIG. The compressed air is injected downward and the seam edges α1. By pressing α2 inward, the bag α
The bag α, which has been inflated by opening the upper end filling port α3, is thrown into the bag support base A as shown by the imaginary line in the figure, placed on the transport means shown by the arrow 30, and transported to the filling station S2.
After being filled with content β, the sealing station S3
The upper end filling port α3 is hermetically sealed with the heat seal bar 31 of the heat sealer, and the full bag α is pulled out and separated from the bag support base A at the final separation station S4, and the full bag α is transferred to the next process. On the other hand, the bag support stand A is recovered to the bag input station S1 and is repeatedly used for circulation as described above.

Filling nozzle mechanism 1 of rotary set high speed liquid filling machine 12 shown in FIG. 4 for filling liquid content β by rotary set high speed liquid filling machine 12 at filling station S2
To explain with reference to a vertical cross-sectional view of three parts, the rotary complete high-speed liquid filling machine 12 has a bottom surface 33 of a tank 32 at equal intervals in the circumferential direction of the rotary complete high-speed liquid filling machine 12 for commercially available hard containers such as cans and bottles. The lower end of the filling nozzle mechanism 13 provided in the tank 32 has been improved for use in a bag, and a metering liquid ejecting tube 35 in which a slide sleeve 34 is slidably fitted from below is inserted around the bottom 33 of the tank 32. A valve port 39, which is fixed to the bottom opening of the slide sleeve 34 at equal intervals with mounting bag nuts 36 and has a chip receiving surface 38 penetrated through the center of the downward concave surface 37a, is screwed to the lower opening of the slide sleeve 34, while the chip receiving port Stem 4 with a nozzle tip 40 fixedly attached to the lower end to fit correspondingly to 38.
A guide 6 pipe 43 is installed vertically in the metering liquid ejecting tube 35 at the axis of the slide sleeve 34 via an integral lower receiving plate portion 42 with which the upper end of the slide sleeve 34 comes into contact.
and a cylindrical block 45 that extends between the through holes and is slidably fitted therein, and is able to freely come into contact with the upper surface of the metered liquid dispenser cylinder 35 at the upper end of the through-hole at the top end of the metered liquid dispenser cylinder 35, passing through the cylindrical block 45 that is slidably fitted therein. Locking ring 4
6 is fixed and hangs down in contact with the locking ring 46, and the downwardly expanding step 47 at the lower end of the metering liquid dispenser tube 35 and the slide sleeve 34 are removed by compression that is interposed between the cover 48. A coil spring 49 and a coil spring receiving hole 5 recessed in the cylindrical block 45.
Due to the cooperative elastic action of the compression coil spring 52 interposed between the zero bottom and the spring receiving flange 51 fixed to the stem 41, the slide sleeve 34 is urged to constantly protrude from the lower opening of the metered liquid dispenser cylinder 35. At the same time, the stem 41 is always urged to have a rising habit, and the lifting plate 11 of the special filling support stand A is
The lower end opening edge 17 is attached with the elastic body 16 which is pushed up and comes into contact with the lower end opening edge 17.
A filling nozzle cover 15, which has a nozzle port 14 extending directly through the downward concave portion 37 of the valve port 39 and which is inserted and engaged with the filling port α3 of the bag α, is attached to the top of the valve port 39. A filling nozzle mechanism 13 is provided.

In the figure, 53, 54, and 55 are openings, and 56 is a lift mechanism lid plate.

The rotary set high-speed liquid filling machine 1 is transferred from the bag input station S1 to the filling station S2 by the conveying means 30.
The bag support stand A holds the bag α transferred to 2 upright.
is transferred onto the lifter plate 56 of the lift mechanism of the rotary complete high-speed liquid filling machine 12, and as the lifter plate 56 rotates, the lifter plate 56 rises, and the filling nozzle cover 1 of the filling nozzle mechanism 13 rotating in synchronization with the lifter plate 56
As shown in the figure, the upper surface of the push-up plate 11 pushes up and comes into contact with the lower end opening edge 17 to which the elastic body 16 of No. 5 is attached, while the nozzle port 14 fits into the upper end filling port α3 of the bag α.

When the lifter plate 56 further rises from the illustrated state, the slide sleeve 34, the guide core tube 43, and the cylindrical block 45 move against the elastic force of the compression coil spring 49 through the filling nozzle cover 15, which the upper surface of the uplift plate 11 contacts. The upper opening 53 of the metered liquid dispenser cylinder 35 is raised integrally with the cylindrical block 45 and the lower opening 54 is opened with the sliding sleeve 34.
On the other hand, as the cylindrical block 45 rises, the compression coil spring 52 and the spring receiving flange 51 cause the slide sleeve 34° to close the cylindrical block 45.
The stem 41 rises integrally with this, and when the spring receiving flange 51 of the stem 41 comes into contact with the ceiling of the metering liquid dispenser 35 like the virtual greenstone in the figure, it further resists the elastic force of the compression coil springs 49 and 52. slide sleeve 34. When the guide tube 43 and the cylindrical block 45 are raised, a gap is created between the nozzle tip 40 and the tip receiving surface 38, and the liquid content β that was waiting to flow into the metered liquid output tube 35 from the tank 32 is removed. The bag α flows down through the funnel-shaped nozzle opening 14 from the gap.
When the amount is filled, the lifter plate 56 starts to descend, and the slide sleeve 34 is also lowered by the action of the compression coil spring 49, and the tip receiving opening 38 is closed by the nozzle tip 40. As the stem 41 is lowered, the spring receiver flange 51. Due to the action of the compression coil spring 52, the cylindrical block 45 and the guide tube 43 also descend following the descent of the slide sleeve 34, returning to the state shown in the figure, and the contents β for next filling are transferred to the tank 3 through the opening 54.
2 into the quantitative liquid outlet cylinder 35 and waits.

As described above, according to the bag support base A of the present invention, the bag α is accommodated in the bag support base A when the content liquid is filled by contacting the filling nozzle mechanism 13 of the Rotano complete high-speed liquid filling machine 12 and pushing up. Since it has a push-up plate 11 that holds and abuts on the filling nozzle cover 15, the filling nozzle mechanism 13 can be pushed up against the bag α reliably without applying any load to the bag α. Furthermore, during the period up to the separation station S4, where the retaining protrusions 23 and 24 pull out and separate the full bag α after filling the contents from the bag support A, vibrations caused by conveyance etc. The separation station S prevents the swelling of the lower part of the full bag α that occurs.
In step 4, the swollen lower part of the full bag α will not be pulled out from the holding hole 10 and the separation will not be performed properly, etc. Further high-speed operation, reliability, and operation rate of the high-speed automatic bagging and sealing line are achieved. It has the excellent effect of improving
