Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for automatically filling a tray or the like on a continuously moving belt conveyor with prepared foods, paste products, and other pasty plastic materials, such as salad and hamburger materials.

Conventionally, a device for the above purpose supplies a pasty plastic material from a pressure pump to a filling mechanism consisting of a reciprocating cylinder and a reciprocating rotary valve, connects a hose, etc. to the outlet of the filling mechanism, and Some products are packed in trays on a conveyor belt.

However, with this type of filling device, it is difficult to cut out a fixed amount, and the cutting itself is not always smooth.

Furthermore, when cutting hamburger material, it is extremely difficult to cut the same material into a constant flat shape.

The present invention was created in consideration of the current situation, and its purpose is to provide a device that can automatically and reliably fill a tray on a belt conveyor with a fixed amount of a paste-like plastic material such as salad. This is what I am trying to do.

In the present invention, a paste-like plastic material flows from a pressure pump 1 through a pressure hose 2, an injection port 3, etc. into an inner chamber of a filling mechanism consisting of a reciprocating cylinder 4 and a reciprocating rotary valve 5, and flows out from the rotary valve 5. A molded cylinder 7 is connected to the side, and the outflow port of the rotary valve 5 is communicated with the cylinder inner chamber 10 through a passage 9 provided in a piston 8 that reciprocates within the cylinder mechanism, and the lower end of the cylinder inner chamber 10 is connected. A shirt cap 11 that can be opened and closed is attached to the shaft cap, and a fixed amount of paste-like plastic material is intermittently dropped from the shirt cap 11 by interlocking the operations of the filling mechanism, the molding cylinder 7, and the shirt cap 11. Deli items, paste products,
The present invention also relates to an automatic tray filling device for pasty plastic material.

The details of the above configuration are shown in FIGS. 3 to 7. First, in FIG. 3, the reciprocating rotary valve 5 moves freely back and forth within the casing 13 having a cylindrical space 12 therein. Swinging partially cut-out rotary shaft 1
4, and the casing further has a left-hand opening and a right-hand opening communicating with the inlet 3 and the molding cylinder 7, respectively.

Further, a reciprocating cylinder 4 is disposed above the rotary valve 5, and a material suction space 15 is formed within the cylinder.
are alternately communicated with the injection port 3 and the molding cylinder 7 by the reciprocating motion (oscillation) of the rotary shaft 14.

With the above configuration, the material pressure-fed to the injection port 3 is sucked into the suction space 15 in the reciprocating cylinder 4 through the left opening of the casing 12 by the counterclockwise rotation of the rotary valve 5 and the upward movement of the reciprocating cylinder 4, and then The material sucked in by the clockwise rotation of the rotary valve 5 and the lowering of the reciprocating cylinder 4 is brought into the forming cylinder mechanism 7 via the casing interior 12 .

At this time, specifically, the material is fed through an L-shaped passage 9 provided in the piston 8 into the filling space 10 formed between the shirt starter 11 and the piston 8, and gradually moves up and down the piston 8 until the amount of elevation reaches the set value. When this happens, the piston 8 is intermittently or continuously lowered by the piston drive mechanism 16 using a limit switch or the like in synchronization with the filling mechanism, and the shirt starter drive mechanism 17 is interlocked with the above operation to lower the shirt starter 10. Belt conveyor 1 arranged below
A certain amount of pasty plastic material, such as salad, can be continuously filled into the tray above 8.

Furthermore, Fig. 3 also shows a belt conveyor lifting mechanism used when making hamburgers, etc., instead of salads, and this mechanism is equipped with two rollers 19 that support the middle of the upper horizontal portion 18a of the belt conveyor 18, and the same rollers. It consists of a lifting rod 20.

The shirt shutter 11 and the shirt shutter drive mechanism 17 are shown in detail in FIGS. 4 and 5. In the figures, 21 is a horizontal rod that moves laterally by a drive mechanism that will be described later, and 22 is a horizontal rod that connects the main body frame 2.
An L-shaped lever 24 is rotatably supported by 3 and has one end connected to the horizontal rod 21, and 24 has one end connected to the other end of the L-shaped lever and holds the base end of the shirt stopper 11 at the other end. It is a reciprocating rod.

By operating the horizontal rod 21 with the above configuration, L
The mold lever 22 swings, and the swing causes the shutter 11 to open and close the molding opening provided at the lower end of the molding cylinder 7, thereby filling the tray with the paste-like plastic material.

Further, a driving device 25 for driving the filling mechanism, the molding cylinder mechanism 7, etc. in an interlocking state or synchronously is shown in FIGS. 6 and 7, in which 30 is a drive motor, 31 is a speed reducer, and 32 is a A first drive side mechanism swings the rotary shaft 14, 33 a second drive side mechanism that drives the reciprocating cylinder 16, and 34 a molding elevator.

Note that 35 is a belt conveyor lifting mechanism, and 36 is a clutch mechanism.

Next, the operation of the tray filling apparatus having the above structure will be explained with reference to FIGS. 1, 3, and 3.

First, a paste-like plastic material such as salad is fed under pressure from a pressure pump 1 through a pressure feed hose 2 to an injection port 3, and further fed into a reciprocating cylinder 4 via a reciprocating rotary valve 5.
Next, the rotary shaft 14 is reversed, and the material in the reciprocating cylinder is passed through the rotary valve 5 and the passage 9 provided in the piston 8 of the molding cylinder mechanism 7, and then transferred to the shirt cylinder 11 provided at the bottom of the reciprocating cylinder. It is fed into the space 10 between the bottom surface of the piston 8, and when the piston 8 reaches the set position, the molding cylinder mechanism 7 is actuated using a limit switch or the like to continuously or intermittently lower the molding cylinder mechanism 7, and in conjunction with the lowering. Then, the filling mechanism such as the rotary valve 5, the belt conveyor 18, the shutter mechanism 17, etc. are operated, and a fixed amount of paste-like plastic material such as salad is sequentially filled into the tray flowing on the belt conveyor.

Also, if the pasty plastic material is a hamburger,
Furthermore, the belt conveyor lifting mechanisms 19 and 20 are operated to raise the upper horizontal portion 18a of the belt conveyor 18, and the hamburger material is flattened between it and the shutter.

In the case of hamburgers, the belt conveyor 18 is operated intermittently.

As described above, the filling device according to the present invention can be used for salads,
It is possible to reliably and fully automatically fill or mold a fixed amount of pasty plastic material such as hamburger steak.
