Description

[Detailed description of the invention] The present invention relates to an apparatus for producing spherical foods such as meatballs.

When manufacturing spherical foods such as meat dumplings, the most important thing to be careful of is to ensure that the numerous spherical foods produced are of equal size and weight, and to prevent variations among the spherical foods as much as possible. It is something that must be done.

In this respect, in conventional manufacturing equipment of this kind, the ingredients sent out from the hopper are once fed into a measuring cylinder via a switching cock, are weighed to a certain extent by the measuring cylinder, and then are weighed. By switching the switching cock again, the ingredients are sent from the measuring cylinder to the forming cock that forms them into a spherical shape, but the measurement is not accurate.
Therefore, there is a problem in that the spherical food produced has a considerable variation in size, etc., and when the passage leading from the hopper to the measuring cylinder is communicated by switching the switching cock as described above, the molding from the measuring cylinder is difficult. The passage leading to the cock is blocked, and conversely, when the former is blocked, the latter is opened, and the spherical food is taken out only intermittently by switching the switching cock. The disadvantage is that manufacturing capacity is low.

This invention is mainly aimed at overcoming the above-mentioned difficulties, and will be explained below with reference to the drawings showing one embodiment of the invention. Reference numeral 1 indicates a hopper, and inside the hopper, meat etc. are minced. Ingredient A made by shredding into pieces and kneading them
The ingredients A are forcibly delivered to the lower part of the hopper 1 through an outlet 3 by ingredient feeding rollers 2, 2 which are mounted on a shaft to rotate in the direction of the arrow.

Reference numeral 4 denotes a switching cock for filling ingredients, which is provided in communication with the above-mentioned delivery port 3, and the switching cock 4 is connected to a pair of filling cylinders 5 and 6 by sandwiching the switching cock.
The filling pistons 7.8 fitted in the pistons 7, 8 are pivotally connected to the swinging arms 11 and 12 about fulcrums 9 and 10, respectively, and both swinging arms 11 and 12 are connected to the connecting rod 13 and driven in synchronization with each other. At the same time, when the delivery port 3 of the hopper 1 and the filling cylinder 5 are in communication with each other through the switching cock 4, the filling piston 1 is driven backward so that the ingredients A delivered from the delivery port 3 are sucked and filled into the filling cylinder 5. At this time, the switching cock 4 connects the other filling cylinder 6 with a passage 14 leading to a metering switching cock 15, which will be described later, and the filling piston is configured to push out the ingredients A in the filling cylinder 6 into the passage 14 and the measuring cock 15. 8 is driven forward.

Note that this switching cock 4 is provided with a relief groove 33 as appropriate.
The overfilled ingredients A are sent back to the hopper 1 side again.

A four-way rotary metering switching cock 15 is communicated below the filling cock 4 via a passage 14, and the metering switching cock 15 is alternately communicated with a pair of measuring cylinders 16 and 17 located between the cocks. , both metering cylinders 16.1
Metering pistons 1B and 19 are fitted into the filling cylinders 7 and 19, which are retracted only by the pressing force of the tool A that is forcibly fed into the cylinder body 16a or 17a from the filling cylinder 5 or 6 via the filling switching cock 4, and both metering pistons 18
．． 19 are alternately driven forward by pressing arms 20, 21 that press the rear end surface.

That is, one pressing arm 21 is connected to a drive shaft 22 and an adjusting rod 23 that are driven up and down by a cam mechanism (not shown), and the other pressing arm 20 is connected to one pressing arm 21 by a connecting rod 24. Therefore, both pressing arms 20,
21 is designed to swing left and right in synchrony around fulcrums 25 and 26, but when the passage 14 leading to the filling cylinder 16 and the metering cylinder 17 are in communication with each other by the metering switching cock 15, the cylinder body The metering piston 19 is moved backward by the pressing force of the tool A that is forcibly fed into the metering piston 17a, and at this time the suppression arm 21 is separated from the rear end surface of the metering piston 19. The measuring cylinder 16 is in communication with a passage 27 leading to a molding nozzle cock 28, which will be described later. It's like being pushed out.

A molding nozzle cock 28 for molding the ingredient A into a substantially spherical shape is communicated with the lower part of the measuring switching cock 15 via a passage 27.
The passage 27 of the nozzle cock 28 as shown in FIG.
The true number inlet 29 that communicates with the passage 2T is formed in the opening edge 28a, which has a partially large diameter, so that it always communicates with the passage 2T even if the nozzle cock 28 is switched for reasons described later. As shown in FIG. 2, the true number outlet 30 is surrounded by an opening 32 consisting of a sharp knife edge 32a of a cock body 31 that supports the cock 28.

The molding nozzle cock 28 has a cylindrical shape, and is rotated about its horizontal axis in the direction of the arrow in FIG. 1 by a cam mechanism (not shown).

Depending on the rotational position of the molding nozzle cock 28, the degree of overlap between the true number outlet 30 and the opening 32 of the cock body 31 changes, and as a result, the degree of opening of the opening 32 is changed.

To explain how the degree of opening of the opening 32 changes, first, as shown in FIG.
The opening degree gradually increases accordingly.

When the anti-number exit 30 and the opening 32 are in the same position (
The state shown in FIG. 2) is the maximum opening degree, and then the nozzle cock 28 rotates counterclockwise to reduce the opening degree and return to zero again.

While the degree of opening changes in this way, the tool pushed out by either of the metering pistons /18, 19 passes through the metering switching cock 15 and the passage 27, enters the nozzle cock 2B from the opening edge 28a, and enters the nozzle cock 2B from the opening edge 28a. An amount corresponding to the opening degree of the portion 32 is extruded and formed into a spherical shape.

In reality, this shape is not perfectly spherical as it is affected by the cross-wire condition of the ingredients, but it is almost spherical as a whole, and the total amount is accurately measured by the amount of movement of the measuring pistons 18 and 19. and has been sufficient for food so far.

Therefore, according to the present invention, when the measuring cylinder is filled with the forcibly fed ingredients of the hopper 1 through the switching cock, the measuring switching cock 15 is formed of a four-way opening rotary cock. Since it is designed to alternately communicate with a pair of measuring cylinders 16° and 17 located between the The ingredient A in the other measuring cylinder 16 is sent to the molding nozzle cock 28 via the switching cock 15, and when the ingredient A is filled into the one measuring cock 17, the switching cock 1 is
5 is switched, and the other measuring cylinder 16 is continuously loaded with tool A.
is filled, and ingredients A are extruded from one measuring cylinder 1T. In this way, ingredients A from the hopper 1 are continuously fed out instead of intermittently as in the conventional case, and continuously from the molding nozzle cock 28. Since the food is taken out as a roughly spherical food, the production capacity can be greatly increased.

Furthermore, the measuring cylinders 16 and 17 for measuring the ingredients A move backward only by the pressing force of the ingredients A that are forcibly fed into the respective cylinder bodies 16a and 17a! Piston 18,1
Since the ingredient A filled in the measuring cylinder is measured by the amount of retraction of 90, the measuring piston will not retreat unless the ingredient A is filled into the cylinder body in a predetermined amount and with a predetermined density. Therefore, the set amount of the tool A can be accurately measured by moving the measuring pistons 18 and 19 backward by a predetermined stroke.

Furthermore, the ingredient A pushed out from the measuring switching cock 15 is fed into the forming nozzle cock 28, and as shown in FIG. The nozzle cock 28 swings as shown in FIG. 3 to separate the tool A from the true number outlet 30. At this time, the periphery of the opening 32 of the molding nozzle cock is formed into a sharp knife 32a. It is possible to reliably cut the continuous ingredients A into a predetermined amount.

In addition, when finishing a spherical food product for a predetermined amount, it is preferable that the ingredients A are continuous up to the true number outlet 30 of the molding nozzle cock 28. For example, the nozzle cock 28 is oscillated as shown in FIG. Tool A that moves and continues at the antilog entry 29
If the ingredient A is cut, the discontinuous part will become discontinuous at the cut part, and there is a risk that the discontinuous part will be cut off and taken out from the cut part 30, or that the spherical food product to be formed will be deformed from the defective cut part. However, according to the present invention, as shown in FIG. 2, the periphery of the inlet 29 is partially formed into an opening edge 28a having a large diameter in the direction of swinging force, and as shown in FIG. Even when the cock 28 swings, the true number inlet 29 is always in communication with the passage 27 leading to the switching cock 15, so the tool A is not cut midway and is therefore reliably kept in a good shape. can produce spherical foods.
