Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a retort food filling machine, in particular,
The present invention relates to an improvement in an apparatus for quantitatively filling a product bag with a retort food made of a viscous fluid containing solids and fibers such as pieces of meat and vegetables, such as curry sauce.

[Prior art] A process of continuously manufacturing individual product bags by joining and cutting rolled film-like sheet materials such as aluminum foil and synthetic resin, and a process of continuously manufacturing individual product bags, and retort foods such as curry sauce to be filled into the bags. A bag making and filling machine for retort food is conventionally known, which combines a step of feeding a fixed amount at a time and fills and seals a fixed amount of retort food into a bag from a nozzle facing the opening of the bag. However, if the retort food to be filled contains solid or fibrous substances such as pieces of meat or vegetables, the nozzle may not be sharp enough to cause over- or under-dose, or droplets may fall from the nozzle. This causes problems such as staining the bag surface, which is unsanitary, and also staining the sealing surface, resulting in poor sealing.

[Problems to be Solved by the Invention] In view of the problems of the prior art described above, the present invention is directed to the bag making and filling of retort foods made of viscous fluid containing solids or fibers such as pieces of meat such as curry sauce and pieces of vegetables. When opening and closing the nozzle, a guillotine-shaped slide cutter cuts off the solids and fibers, and a rotating piston that moves up and down reliably discharges the residue inside the nozzle into the bag. The purpose is to reliably fill and enclose a certain amount of retort food in a bag in a hygienic manner without causing excess or shortage.

[Means for Solving the Problems] As a means for solving the above problems, the present invention has the following configuration.

A slide feeder 12 is connected to the tip of a flexible tube 10 connected to a quantitative feeder for retort food via a connecting tube 11. A slide plate 13 is integrally provided with a slide cutter 14 having a filling hole 19 that opens and an auxiliary hole 19' that opens to the outside. A fixed cutter 15 having an opening is provided, and the filling hole 19 and the auxiliary hole 19' are alternately communicated with the nozzle 16 by sliding the slide plate 13.

Further, the nozzle 16 is located above the nozzle 16.
A rotary piston rod 24 that moves up and down while rotating concentrically with the nozzle 16 is disposed, and the lower end of the rotary piston rod 24 is provided with an extrusion head 23 having an outer diameter that matches the inner diameter of the nozzle 16.

[Examples and effects] This will be explained below with reference to FIGS. 1 to 9.

In Fig. 1, numeral 9 is the hopper of the retort food quantitative feeder, and the material stored in this hopper is
The bag 31 is filled through the flexible tube 10 and the nozzle 16 by the mechanism described below.

Reference numeral 1 denotes a cam box, which is fixed to the main body frame, and has a built-in cam (not shown) for driving a T-shaped lever 2 within the cam box 1. The T-shaped lever 2 is constantly pulled diagonally downward in FIG. 1 by a spring 3. Now, the cam (not shown) is the first one.
When the T-shaped lever 2 is rotated in the direction of the arrow in the figure and the right end of the T-shaped lever 2 is pushed down at the convex portion, the T-shaped lever 2 is rotated clockwise against the tension of the spring 3. In response to this movement, the L-shaped lever 4, the link 5 connected thereto, and the piston 7 connected to the link 5 move to the first position.
It is pushed out to the right in the figure (downward in Figure 3).

When the piston 7 moves to the right, a limit switch is actuated at its end, and the three-way valve 8 is switched to communicate the cylinder 6 and the hopper 9. (Figures 1 and 4).

Then, as the piston 7 moves to the left as the next movement, the filling in the hopper 9 is sucked into the cylinder 6. (Figure 4).

When the piston 7 reaches the left end, the three-way valve 8 is switched by the operation of the limit switch, and the cylinder 6 and the flexible tube 10 are now in communication. Next, as the piston 7 moves to the right, the filling that has been sucked into the cylinder 6 is forced into the flexible tube 10 side. (Figure 5).

In this manner, the filling in the hopper 9 is supplied in a fixed quantity to the flexible tube 10 by the reciprocating movement of the piston 7. (The above is conventionally known).

A slide feeder 12 is connected to the tip of the flexible tube 10 via a connecting tube 11.

A slide plate 13 equipped with a slide cutter 14 having a filling hole 19 that communicates with the connecting pipe 11 and an auxiliary hole 19' that opens to the outside is integrally provided on the lower surface of the slide feeder 12. There is.

On the other hand, the filling hole 1 is provided on the upper surface of the nozzle 16.
9. A fixed cutter 15 having an opening having the same diameter as the auxiliary hole 19' is provided.

Therefore, by sliding the slide plate 13, the filling hole 19 and the auxiliary hole 19' alternately communicate with the nozzle 16.

The slide plate 13 is interlocked with the movement of the three-way valve 8, and when the piston 7 moves to the right (when the cylinder 6
and the flexible tube 10), the filling hole 19 communicates with the nozzle 16 (FIGS. 2 and 5).
When the piston 7 moves to the left (when the cylinder 6 and the hopper 9 are in communication), the auxiliary hole 19' communicates with the nozzle 16 (Fig. 1, Fig. 6). Figure 4, Figures 7-9).

In addition, in the figure, 17 is a slide feeder holding device equipped with a roller for pressing the slide feeder 12 at the lower part, and 18 is its support frame. Further, 20 is a vertically movable frame which is moved vertically by a vertically movable shaft 21 to adjust the position between the nozzle 16 and the bag 31.

Referring again to FIG. 2, another vertically moving shaft 29 is moved vertically by the operation of a cam and a link mechanism or an air cylinder, and this movement is transmitted through a receiving plate 30.
A frame 26 supporting a fixed cylinder 25 of a rotary piston device 22 is moved up and down. The rotary piston device 22 is disposed above the nozzle 16 and concentrically with the nozzle 16. A rotary piston rod 24 that moves up and down while rotating is built in the fixed cylinder 25 of the rotary piston device 22. A rubber extrusion head 23 is attached. This extrusion head 23
The outer diameter of the nozzle 16 is approximately equal to the inner diameter of the nozzle 16. Note that a pinion 27 is fixed to the top of the rotating piston rod 24 and rotated by a motor 28.

As described above, when the piston 7 moves to the right, the filling that has been sucked into the cylinder 6 is fed under pressure to the flexible tube 10 side, and from the slide feeder 12 via the connecting tube 11 to the filling hole 19 and the nozzle. 16 into the bag 31.

At the same time when the piston 7 reaches the right end and discharge of a predetermined amount ends, the slide 13 slides to the right in FIG. 2 and the feed stops.

At this time, the pieces of meat, vegetables, etc. caught in the middle are cut vertically by the slide cutter 14 integrated with the slide plate 13 and the fixed cutter 15 integrated with the nozzle 16, as if cut by a guillotine. be.

In this way, when the slide plate 13 moves to the right, the auxiliary hole 19' and the nozzle 16 match (Fig. 7).
The extrusion head 23 is lowered and inserted into the nozzle 16 through the auxiliary hole 19', and the filling remaining in the nozzle 16 is completely scraped off and stuffed into the bag 31 (FIG. 8).

At this time, the rotating rod 2 of the rotating piston device 22
As the extrusion head 23 at the lower end of 4 rotates,
The filling material adhering to the lower surface of the extrusion head 23 is also completely shaken off by the centrifugal force and falls into the bag 31 (FIG. 9).

[Effects] According to the present invention, the slide feeder 12 is connected to the tip of the flexible tube 10 connected to the quantitative feeder for retort food via the connecting tube 11, and the lower surface of the slide feeder 12 is is integrally provided with a slide plate 13 equipped with a slide cutter 14 having a filling hole 19 that opens in communication with the connecting pipe 11 and an auxiliary hole 19' that opens to the outside. Filling hole 19, auxiliary hole 19'
A fixed cutter 15 having an opening with the same diameter is provided,
By sliding the slide plate 13, the filling hole 19 and the auxiliary hole 19' alternately communicate with the nozzle 16, and above the nozzle 16 is a rotary piston rod 24 that moves up and down while rotating concentrically with the nozzle 16. The extrusion head 23 having an outer diameter matching the inner diameter of the nozzle 16 is provided at the lower end of the rotating piston rod 24.
Even if the retort food to be filled into the retort food container 1 contains solid or fibrous materials such as pieces of meat or vegetables, after filling the predetermined amount, the fixed cutter 15 and the slide feeder installed at the top of the nozzle 16 With the slide cutter 14 provided on the lower surface of the nozzle 12, pieces of meat, vegetables, etc. sandwiched between the two are cut vertically as if by a guillotine. Since the extrusion head 23 at the lower end completely scrapes the meat into the bag 31, quantitative filling is performed reliably, there is no excess or deficiency in the amount of filling, and it is possible to avoid the phenomenon of pieces of meat falling off. This has the effect of allowing retort food to be filled and sealed in a hygienic manner without staining the surface or sealing surface of the bag 31.
