Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a meatball used in an apparatus for producing ham by forcing meat into a cylinder and extruding it from the cylinder into a casing.

A ham manufacturing apparatus is known in which a piece of meat is placed in a circular groove, pushed into a cylinder, then cut, the cylinder is displaced, and the meat piece inside the cylinder is then pushed out into a casing. (Unexamined Japanese Patent Publication No. 56-154737
In order to push out the meat in the cylinder, the above device is provided with a piston-shaped bushing approximately equal to (slightly smaller than) the inner diameter of the cylinder at the tip of the rod, and the meat is pushed out by the bushing.

However, in conventional devices, the entrance of the cylinder is tapered, and the radius changes at this position. Furthermore, in the case where the cylinder is divided into an outer side and an inner side and these are fitted into a telescopic link, the radius changes depending on the joining position of these parts. Further, a nozzle is provided at the outlet end of the cylinder, and the inner diameter of the nozzle gradually decreases from the outlet end toward the outside.

Therefore, the radius of the nozzle portion also changes.

As mentioned above, with conventional equipment, when pushing out a lump of meat, the inner diameter of the cylinder etc. changes depending on the position of the bushing, and when using a bushing with a fixed radius, residual meat remains inside the cylinder or nozzle, making it difficult to quantify. It will be lacking in.

In addition, since the meat is not pushed out with the full inner diameter of the cylinder, a shift occurs between the meat on the inside (the part pushed by the bushing) and the outside (the part not pushed by the bushing), which deteriorates the appearance.

In addition, if the green meat is damaged, it means that the green meat remains in the cylinder9, which further aggravates the deterioration of quantitative performance.

When changing, the bushing must also be replaced to match the cylinder diameter, and there is no versatility in handling.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method and method for tracing a lump that eliminates damage to meat lumps, eliminates residual meat inside cylinders and nozzles, thereby improving quantitative performance, and at the same time being compatible with a wide variety of cylinders. This applies to those who intend to provide equipment.

First, an example of a conventional ham manufacturing apparatus will be explained. An example of this is the one shown in the above-mentioned Japanese Patent Laid-Open No. 164737/1983.

Referring to FIG. 1, a piece of meat is placed in the supply section 1 and pushed into the cylinder 5 with the push button 2.

The cylinder 3 consists of a large-diameter outer cylinder 31 and a small-diameter inner cylinder 32, which are telescopically fitted to the outer cylinder 51. Then, the distance is changed by telescopically expanding and contracting. The cutter 4 cuts the seam when the meat is pushed into the cylinder 3, and the cylinder 3 and the meat after cutting are displaced and move downward as shown by 6' in the figure. At this position, the meat is extruded by the extruder 5 through the nozzle 6. A casing 7 is placed over the nozzle B, and the meat mass is extruded into the casing 7 to make ham. A taper 8 is provided at the entrance of the cylinder 6', and the button 5
This makes it easy to fit into the cylinder 3'.

An example of the relationship between the inner diameters of the conventional device is shown in FIG. 2.

The bushing 5 enters from the inner cylinder 32 at the right end in the figure, then from the outer cylinder 31. It moves to the nozzle 6 and the casing 7. When moving from the inner cylinder 62 to the outer cylinder 61, the inner diameter does not become thicker, but inside the nozzle 6, the inner diameter gradually becomes smaller. Then, the inner diameter increases at the point where it moves from the nozzle 6 to the casing 7.

Therefore, in the conventional device, the outer diameter of the bushing must be made smaller than the minimum inner diameter (for example, the inner cylinder diameter) in the path of the bushing, but this results in the occurrence of residual meat at the point where the inner diameter is small, and the outer diameter of the meat lump. This will result in a misalignment between the inside and outside.

Therefore, the present invention provides a bushing 10 having an outer diameter as shown in FIGS. 3(a), 3(b), and 3(c).

A shaft 12 is provided at the center of the circular front surface 11, and a disk portion 13 and a threaded portion 14 are formed on the shaft 12.

The disk portion 13 has an annular groove 15 in the center and six notches 16. A swinging piece 17 is provided in each of the notches 16 so as to be swingable about a pin 18, and the pin 18 is fitted into the groove 15. One end of the swing piece 17 cooperates with the front face 11 to constitute the front face of the bushing 10, and the other end of the swing piece 17 is provided with a recess 19. By fitting one spring ring 20 into the recess 19, the pin 18 The one end of the swinging piece 17 is urged in the expansion direction with the axis being the axis. The outer periphery of the swinging piece 17 is circular and approximately matches the inner diameter of a cylinder or the like when expanded.

A rod 21 of an air cylinder or the like (not shown) for reciprocating the bushing 10 is screwed into the threaded portion 14 .

The operation of the present invention configured as described above will be explained with reference to FIG.

When the bushing 10 is inside the inner cylinder 32, the swinging piece 17 contracts in the radial direction as shown at 0) in the figure.

Then, when entering the outer cylinder 31, the swinging piece 17 expands in the radial direction to become as shown in (b). When it enters the nozzle 6, it gradually shrinks as shown in (c), and then enters the casing 7 as shown in). Inside the casing 7, it expands a little in the radial direction.

Since the bushing 10 of the present invention is constructed as described above, the tip of the swinging piece 17 is always urged in the expansion direction by the urging force of the spring ring 20. For this reason, the outer diameter of the bushing 10 changes according to the inner diameter of the cylinder or nozzle, thereby preventing the remaining green meat and preventing the green meat from shifting from the inside to the outside.

Furthermore, according to the bushing of the present invention, meat juice can also be filled into the casing, resulting in a device with no waste.

Note that since the swinging pieces 17 of the present invention compensate for the insufficient diameter of the front surface 11, the six swinging pieces 17 cooperate to make the outer periphery approximately circular. It is desirable that the outer periphery of the end surface be arcuate and the inner periphery of the end surface also be arcuate.

Further, the number of swing pieces 17 is not limited to six,
It is sufficient if there are more than one.

FIG. 5 shows another embodiment of the present invention, in which the swing piece 22
The end of the leaf spring 25 is fixed in the groove 24 by the fulcrum ring 23.
is interposed between the swinging piece 22 and the shaft 26.

In this method, the point of action of the spring in the embodiment shown in FIG. 3 is moved, and a stronger expansion force can be obtained with this method.

In addition, the present invention, as shown in FIGS. 6(a) and (b),
An extension piece 2 is attached to an L-shaped member 28 that can freely swing around a pin 27.
9 is provided so as to be movable up and down in the radial direction. The spring 60 moves the expansion piece 29 upward. The expansion pieces 29 are arcuate, and a plurality of expansion pieces 29 cooperate to form a circular shape. One spring ring 23 at one end of each L-shaped member 28
' is wound around.

According to the methods shown in FIGS. 6(a) and 6(b) above, the extension piece 29
Even if the expansion piece 29 hits an uneven surface, the L-shaped member 28 swings, thereby making it easier for the expansion piece 29 to move up and down in the radial direction.

The embodiments shown in FIGS. 7(a), ←), and (c) are intended to expand the expansion pieces 31 in parallel using parallel links. That is, the expansion piece 31 is supported by two parallel links 32, and a spring ring 63 is wound around the end of one of the parallel links 32 to displace the expansion piece 31 outward. An arcuate plate 65 is held on the front surface of the expansion piece 61 by a pin 34. The pin 34 is inserted into an arcuate elongated hole 36 of an arcuate plate 65. The front surface 67 of the bushing is kept in constant contact with the arcuate plate 55 by a spring 68.

According to the above method, no gap is created even when expanded in the radial direction, and the front surfaces of the arcuate plate 35 and the expansion piece 31 are always perpendicular to the direction of movement of the bushing.

(A) and (B) in Figure 8 are plastic extension pieces 39.
The front surface 40 of the expansion piece 39 can be displaced in the radial direction.

In addition, FIGS. 9(a) and 9(b) show an elastic material 41 such as a sponge covered with an expansion piece 42. In this type, the expansion piece 4
2 is movable in all directions, it can ride over any unevenness.

Now, what has been described above is merely an example of the present invention, and the present invention does not exclude other embodiments.

Incidentally, in the above description, the bushings have been described as being used in an apparatus for producing lumps, but it goes without saying that the bushings of the present invention can be used in other apparatuses for extruding lumps.

Further, the spring ring described above can be replaced with any elastic ring such as a rubber ring, which is also included in the present invention.

The effects of the present invention described above are listed as follows.

No pieces of meat remain inside the cylinder or nozzle, improving quantitative performance.

The meat extrusion work is performed smoothly and failures are reduced.

Since the meatball is extruded by expanding it to its full inner diameter, there is no damage to the meatloaf, there is no misalignment between the inside and outside of the meatloaf, and hams of high quality and good appearance can be replaced.

Versatility increases as there is less need to replace the bushings.

Furthermore, the configuration of the present invention has a small number of parts and is easy to disassemble and assemble.
