Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic method and apparatus for producing Viennese sausages in which a substantially fixed amount of meat is enclosed in the intestine and the meat is individually twisted into a chain.

The manufacturing method for chain-shaped Vienna sausages can be divided into three types, based on the rotation of the valve through which the meat is fed: a unidirectional continuous constant rotation method, an oscillating rotation method, and an intermittent rotation method.

The one-way continuous constant-velocity rotation system is one in which the valve rotates continuously in one direction at a constant velocity, which is advantageous because the structure is simple and the meat can be fed at a high speed. The efficiency of feeding meat into the chamber provided inside is poor, and the efficiency of discharging meat from the chamber is also poor.

In the oscillating rotation method, the valve oscillates (reciprocating rotation), and in the intermittent rotation method, the valve pauses and rotates, but in both cases, the feeding speed of the meat is limited to one direction. This is disadvantageous compared to the continuous constant speed rotation method.

The purpose of the present invention is to inherit the unidirectional continuous rotation system, improve the feeding speed of meat by making the rotational speed of the valve non-uniform, and improve the feeding efficiency of a chain-shaped Vienna sausage automatic. The purpose is to provide a manufacturing method and apparatus.

First, a conventional device will be explained in order to deepen the understanding of the present invention.

FIG. 1 schematically shows a conventional Viennese sausage manufacturing apparatus.

A chamber 2 into which meat is fed is formed within the valve 1.
A meat feed passage 3 and a meat discharge passage 4 are provided on the circumferential surface of the valve 1.

A nozzle 5 is provided in the discharge passage 4, and the intestine 6 is placed over the nozzle 5.

A twisting device 7 is provided at the end of the nozzle 5, and by rotating together with the nozzle 5, the meat enclosed in the intestines 6 is individually twisted into a chain shape.

When the meat matches the feeding passage 3 and the opening 8 of the valve 1,
It is fed into the chamber 2 from the feeding passage 3.

This action is to feed the gas into the chamber 2 by means of a metering piston (not shown).

Then, when the valve 3 is rotated so that the opening 8 aligns with the discharge passage 4, it is pumped into the discharge passage 4 by the metering piston.

The meat discharged from the tip of the nozzle 5 becomes individual chained Wiener sausages as shown by W in FIG. 1, but the chain C is twisted multiple times by the twisting device 7.

This twisting action is performed by rotating the twisting device 7 and the nozzle 5.

In the one-way continuous constant velocity rotation system, the valve 1, nozzle 5, and twisting device 7 are each suitable for continuous constant velocity rotation.

Therefore, the following drawbacks occur in the unidirectional continuous constant rotation method.

Now, if the communication cross-sectional area between the opening 8 of the valve 1 rotating at a constant speed and the feeding passage 3 is S, the communication cross-sectional area between the opening 8 and the discharge passage 4 is S, and the time is T, then the chamber 2 The amount of meat fed into and the amount of meat discharged is represented by Q and Q' in FIG. 2, respectively.

As can be seen from Fig. 2, in the continuous constant rotation method, the rotational speed of the valve 1 is constant regardless of the size of the communication cross-sectional area S2g, so the time in the region where s and s' are small is long; The amount of supply and discharge in that area is small.

Furthermore, since the twisting device 7 and the nozzle 5 are rotated continuously and at a constant speed, the twisting action is performed during the entire process of stuffing the meat into the intestines.

From the above, in the continuous constant speed rotation system, the feeding efficiency was poor and the finish of the Vienna sausage was poor, and in the end, there was a limit to increasing the feeding speed.

In the oscillating rotation method, the valve 1 oscillates and rotates in the left-right direction, but since the direction of rotation of the valve 1 is reversed, there is a drawback that the feeding speed is not sufficient.

In order to increase this feeding speed, it is also known to increase the rotational speed of the valve 1 when the opening 8 of the valve 1 is in the fully closed position (see Japanese Patent Publication No. 11968/1982).

The intermittent rotation method is the same as the above-mentioned continuous rotation method in that the valve 1 shown in FIG. When the two match, the rotation of the valve 1 is temporarily stopped.

This method has a slow feeding speed and poor productivity.

The present invention relates to an improvement of the above-mentioned one-way continuous constant speed rotation system, whose structure is schematically shown in FIG. 3. Inside the valve 11, two chambers 13 are formed by a partition wall 12.

On the outer periphery of the valve 11, there is a meat feeding passage 14 and a meat discharging passage 1.
5 and a metering piston 16 are provided, each with a port)
17, 18 and 19 at its ends.

Ports N7, 1B and 19 communicate with chamber 13 when facing the opening of valve 11.

A nozzle 20 is provided in the discharge passage 15, and the nozzle 2
0 is covered with an intestine 21.

A twisting device 22 is provided at the end of the nozzle 20, and the twisting device 22 and the nozzle 20 rotate together to twist the joints 24 of the sausages 23 into individual chains.

The feeding and discharging of meat into the chamber 13 is as shown in FIG.

First, in the state shown in A, the metering piston 16 reaches the top dead center and begins to stroke downward.

The port 17 of the meat feeding passage 14 is in complete communication with the chamber 13, and the meat is fed into the chamber 13 by lowering the measuring piston 16, but the port 19 is only partially in communication, The feeding efficiency by the piston 16 is poor.

When the metering piston 16 descends to the mouth position, the port 17 begins to be closed by the partition wall 12, and the meat feeding efficiency deteriorates.

When the metering piston 16 reaches the bottom dead center, the partition wall 12 completely closes the port 17 and the feeding of meat ends.

In this state, the port 18 of the meat discharge passage 15 and the chamber 13
The communication with the partition wall 12 is closed by the partition wall 12.

Subsequently, when the metering piston 16 begins to rise, it enters the second state, the port 18 and the chamber 13 begin to communicate with each other, and the discharge of meat begins.

In the second state, the port 18 and the chamber 13 are only partially in communication with each other, so that the efficiency of discharging the meat inside the chamber 13 is poor.

When the state E is reached and the port 18 and the chamber 13 are in complete communication, the meat in the chamber 13 is well discharged, and the meat is fed until the measuring piston reaches the top dead center. Evacuation continues.

In this state, port 19 is completely closed,
Discharge ends.

The above action is performed in two strokes during one revolution of the valve 11.

The twisting action between the Vienna sausages is caused by nozzle 2 in Figure 3.
0 and the twisting device 22 rotate together, and when the meat has been discharged from the end of the nozzle 20, the connection 24 between each sausage is twisted.

The features of the present invention are the valve 11 and the twisting device 2 described above.
2 and the rotational speed of the nozzle 20.

That is, when the rotation speed is constant (uniform rotation), the chamber 13
The cross-sectional area of communication between the port 17 and the ports 17 and 18 exhibits characteristics similar to those shown in FIG.

Therefore, in the present invention, the rotation speed is increased before and after the partition wall 12 closes the ports 17, 18, and 19.

When the rotational speed is converted in this way, the communication cross-sectional area has characteristics as shown in FIG.

Referring to FIG. 5, in the case of constant speed rotation, the curve is shown by the broken line in the figure, but if the rotation speed is increased when the rotation speed is non-uniform, that is, the communication cross-sectional area is small, the curve is shown by the solid line in the figure.

Since the amount of meat fed and discharged is the integral value of each curve, when the rotation of the present invention is performed, the efficiency is improved and the speed can be increased.

However, in the present invention, the rotation of the shaking device 22 and the nozzle 20 is also made at inconstant speed.

That is, in the middle of the stroke in which the meat 75=I]i is being discharged from the end of the nozzle 20, the rotation is slow, and the rotational speed increases near the end of discharge.

Therefore, the finished state of meat encapsulated in the intestines is good.

The basic idea of the present invention has been schematically explained above, and the specific structure of the present invention will be described below.

The valve 31 is fixed to a rotating shaft 32, which is supported in bearings 33, 34 on both sides of the valve 31.

The discharge passage 39 is a double sleeve, with an inner sleeve 41 fixed to a casing 42 of the valve, and an outer sleeve 43 supported by a bearing 44 so as to be rotatable.

A cylindrical seal 45 is fitted between the inner and outer sleeves 41, 43, and is discharged under high pressure to prevent meat from leaking.

A nozzle 46 is fixed to the outer sleeve 43 and a gear 47 is provided.

Said gears 47, 48 are respectively rotated by coaxial gears 50, 51.

The nozzle 46 is covered with an intestine 52, and the meat discharged from the end of the nozzle 46 is individually encapsulated.

An embodiment of the inconstant speed rotation mechanism of the apparatus of the present invention constructed as described above is shown in FIG.

The rotation of the motor M is transmitted to the timing belt 53,
Two gears 54 and 55 are rotated by the timing belt 53.

The gear 54 causes the piston 16 shown in FIG. 3 to reciprocate via the eccentric rocking device 56, and also rotates the lever 57.

The axis of the gear 54 is an eccentric axis on which a pulley 58 and a lever 59 are provided, and a rod 60 fixed to the lever 59 is inserted into a slit 61 provided in the lever 57. It has been supported.

Pulley 58 rotates gear 48.47 via gear 50.51 in FIG.

The gear 55 rotates a lever 63 having a slit 62.

The axial center of the gear 55 means that the gear 6
4. A lever 65 is provided, and a rod 66 provided on the lever 65 is fitted into the slit 62 of the lever 63 and supported.

Gear 64 rotates bevel gear 35 in FIG.

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

When the motor M shown in FIG. 7 operates, the timing belt 53
The gears 54 and 55 are rotated.

The gear 54 on the one hand reciprocates the metering piston 16 via an eccentric rocker 56 .

The metering piston 16 is configured as shown in FIG. 3 and feeds meat into and discharges meat from the chamber 36.

Gear 54 rotates lever 57 on the other hand.

The rotation of the lever 57 causes the lever 59 to rotate via the rod 60.

In this case, since the rotation axes of the lever 57 and the lever 59 are eccentric, the rod 60 is inserted into the slit 61 of the lever 57.
The constant speed rotation of the lever 57 is transmitted to the lever 59 while sliding and reciprocating therein, and the lever 59 rotates at an inconstant speed.

Referring to FIG. 6, the lever 59 rotates at an inconstant speed,
8 to the gear 50.51 and the gear 47.48
rotate at non-uniform speed.

This non-uniform rotation of the gears 47° 48 causes the piston 16
Since the torsion rotational speed is maximized near the end of the stroke of discharging the meat from the nozzle, the torsional rotation speed reaches its maximum when the nozzle reaches near the top dead center, and the finished state of the Viennese sausage is good.

Next, the rotation of the gear 55 causes the lever 63 to rotate at a constant speed, and as described above, the end of the rod 66 fixed to the lever 65 slides and reciprocates within the slit 62 of the lever 63, thereby causing the lever 65 to rotate. Rotate at non-uniform speed.

The inconstant rotation of the lever 65 is caused by the bevel gear 3 via the gear 64 etc.
Rotate 5 at non-uniform speed.

Referring also to FIG. 6, the non-uniform rotation of the bevel gear 35 causes the valve 31 fixed to the same shaft to rotate at non-uniform speed.

The non-uniform rotation of the valve 31 is slower when the communication cross-sectional area between the chamber 36 and the ports 38, 40 of the supply and discharge passages 37, 39 is large, and faster when the communication cross-sectional area is small. , and rotates quickly when the port 19 in FIG. 3 is closed, as described above in FIG. 3.

As described above, according to the present invention, the following remarkable effects are achieved.

First, the efficiency of feeding and discharging meat is improved, which in turn improves the speed of feeding and discharging, or in other words, the speed of filling meat.

Furthermore, the finished state of the Viennese sausage is improved.

Further, when the valve structure of the present invention is adopted, supply and discharge are performed twice per rotation, so that a compact size and high performance can be achieved.
