Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to improvement of a continuous weighing and filling machine for granular foods such as cooked rice and boiled beans.

[0002]

[Prior art]

 When granular foods such as cooked rice and boiled beans are continuously filled in the container by using its gravity, they are easily attached to the filling cylinder or the metering cylinder of the filling device due to the adhesiveness caused by the heating such as cooking rice and boiling. There was a problem that it could not be carried out smoothly and reliably. Therefore, the present applicant has previously developed quantitative filling while further rotating the filling cylinder and the measuring cylinder of the rotating body for filling (see Japanese Utility Model Publication No. 54-42865). In reality, the filling mechanism becomes extremely complicated and costly because it revolves around the axis of rotation, and it is an obstacle to its practical application.

[0003]

[Problems to be solved by the device]

 In view of these circumstances, the present invention utilizes a method of filling raw materials in a semi-boiled state into a container and then heating it under high pressure in recent retort foods, so that granular foods such as cooked rice and beans can be semi-cooked with less stickiness. By filling the container in this state and forming the filling cylinder and the metering tube so that the granular material can easily fall, a very simple structure is achieved without using the complicated mechanism of revolving and rotating the metering tube as in the past. It is an object of the present invention to provide a continuous weighing and filling machine capable of smoothly and reliably filling granular foods such as cooked rice and boiled beans.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is provided with a feed turret and a feed turret on one side, and a filling rotator at the upper part of a turntable having a plurality of container mounting portions around the turret. The rotator for filling is a hopper on the upper side, a filling cylinder continuous to the lower part of the hopper and facing the container mounting part of the rotary table, a metering cylinder installed under the packing cylinder, and upper and lower ends of the metering cylinder. It is composed of a partition plate having a through hole with a phase difference of half circumference provided in the container, and the raw material in the hopper is quantified through the filling cylinder and the quantification cylinder into the container supplied on the container mounting part by the feeding turret. In a continuous weighing and filling machine that is filled and sent out by a turret, the filling cylinder and the measuring cylinder are made of a material having a small friction resistance so as not to rotate but only revolve and the shaft is provided on the inner peripheral surface thereof. Fine ridges are formed in the direction Especially, it is preferable that the filling cylinder and the metering cylinder are formed of tetrafluoroethylene resin having a good sliding property and a small friction coefficient, and further the metering cylinder is formed to be vertically extendable so that the filling amount can be adjusted. is there.

[Embodiment of device]

 An embodiment of the present invention will be described with reference to the accompanying drawings. A feed turret 3 and a feed turret 4 are installed on one side of a turntable 2 around which a plurality of container placement parts 1 are provided, and are conveyed. The container A transferred by the conveyor 5 is transferred and placed on the rotary table 2 via the feed-in turret 3, and the container on the rotary table 2 is sent out and sent out to the carry-out conveyor 6 via the turret 4. Is configured to be able to.

An annular hopper 7 provided at an upper portion of the rotary table 2 and a filling cylinder 8 connected to a lower portion of the hopper 7 and facing the container mounting portion 1 of the rotary table 2. A filling rotation constituted by a fixed quantity tube 9 provided so as to communicate with the lower part of the filling tube 8 and partition plates 10 and 11 fixedly held at the upper and lower ends of the fixed quantity tube 9 so as not to rotate. A body 12 is provided so as to rotate at the same speed as the turntable 2, and a partition plate 10 provided at the upper end of the metering tube 9 is filled with a half circumference portion on the sending turret 3 and sending turret 4 side. 8 and a fixed quantity tube 9 are connected to each other to form a semi-circular arc-shaped long hole 10 ', and a partition plate 11 at the lower end of the fixed quantity tube 9 is formed with a semi-circular arc-shaped long hole 11' on the side opposite to the partition plate 10. It is being touched.

The filling cylinder 8 and the metering cylinder 9 are formed of tetrafluoroethylene resin having a particularly small coefficient of friction, and fine ridges 13 are formed integrally on the inner peripheral surfaces thereof in the axial direction. In addition to facilitating the fall of the granular material, the fixed quantity tube 9 is further formed by a support tube 9'and a vertically movable telescopic tube 9 ", and the telescopic tube 9" is provided with an upper partition plate 10, a filling tube 8 and It is attached to the rotary shaft 14 so as to be vertically adjustable together with the hopper 7 by an adjusting screw 14 ', and is configured so that the quantity of the metering tube 9 can be adjusted.

Since the embodiment of the present invention is configured as described above, the containers A are sequentially fed from the transport conveyor 5 to the container mounting portion 1 of the rotating table 2 which rotates via the turret 3. On the other hand, the granular food such as cooked rice and beans supplied in the hopper 7 of the rotator for filling 12 which rotates in synchronism with the rotary table 2 is fed from the filling cylinder 8 to the long hole 10 'of the partition plate 10. After rotating while being filled up to the inside of the fixed quantity tube 9 via the fixed quantity tube 9, the upper end of the fixed quantity tube 9 is closed by a partition plate 10, and then the lower end part of the fixed quantity tube 9 has a partition plate 11 in a long hole 11. Is rotated to the portion of 11 to drop the filled granular food inside the container A into the container A for quantitative filling, and the container A thus quantitatively filled is delivered by the delivery turret 4. Is carried out by the carry-out conveyor 6 by means of The granular food in the container is smoothly dropped into the container A without being adhered by the fine concavo-convex ridges 13 on the inner peripheral surface of the filling cylinder 8 and the constant quantity cylinder 9 having a low frictional force, and the quantitatively filled container is sterilized under high pressure heat. Is.

Therefore, when the amount of filling the container A is increased, the telescopic cylinder 9 ″ of the metering cylinder 9 is extended upward together with the filling cylinder 8 hopper 7 and fixed to the rotary shaft 14, and the partition plate 10 is After further fixing so as not to rotate, the filling operation is performed in the same manner as described above, whereby the volume of the filling cylinder 9 is adjusted by the expansion and contraction of the expansion and contraction cylinder 9 ″ to adjust the filling amount of the granular food product.

[Effect of device]

 In the present invention, in this kind of continuous metering and filling machine, the filling cylinder and the metering cylinder only for the orbital action are made of a material having a low frictional resistance, especially a tetrafluoroethylene resin, and the inner peripheral surface thereof is provided with a fine uneven line in the axial direction. With a simple configuration, even if the metering tube that weighs while alternately opening and closing the upper and lower ends with a half-circle phase difference is not rotated, the metering tube does not adhere to the granular food that falls from the filling cylinder and does not rotate. A fixed quantity can be weighed and the container can be continuously filled.

Further, in the present invention, since the metering tube only revolves without rotating, it is possible to easily adjust the length of the metering tube and to easily adjust the filling amount by adjusting the quantity of the metering tube. It can be carried out.
