Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pickle liquid injector for injecting a pickle liquid into a raw meat mass such as ham.

[0002]

2. Description of the Prior Art For example, in the process of processing ham, a pickle liquid injection injector is generally used when a pickle liquid is injected into a raw meat mass thereof. That is described in Japanese Patent Publication No. 7-16356. In the injector of this publication, the raw meat block is intermittently fed by the feed conveyor. Further, a large number of injection needles are arranged above the feed conveyor, the pickle liquid is supplied to the injection needles, and at every intermittent feeding of the raw meat mass, the injection needle descends toward the raw meat mass and pierces the raw meat mass. Then, the pickle liquid is injected into the raw meat mass.

[0003] By the way, with regard to raw meat chunks such as ham, in many cases, the raw meat chunks have a hard part and a soft part. For example, in the case of loin, it has a crotch side and a shoulder side, the crotch side is hard and the shoulder side is soft. Therefore, when the injection needle pierces the crotch side and the shoulder side, when the pickle liquid is injected into the crotch side and the shoulder side, the injection conditions vary depending on the hardness of the raw meat mass, and the hard crotch side makes it difficult for the pickle liquid to be injected. , The injection amount is small and on the soft shoulder side,
The pickle liquid is easily injected, and the injection amount is large.

In view of this, in the injector disclosed in the above publication, a pressure adjusting valve is provided in the supply path of the pickle liquid, and the supply pressure of the pickle liquid is adjusted by the pressure adjustment valve.
Further, the pressure control valve is program-controlled by the program control device, and when the hard part of the raw meat mass is at the position of the injection needle, the pickle liquid is supplied at a relatively high pressure, and the soft part of the raw meat mass is formed of the injection needle. When in position, the pickle liquid is supplied at a relatively low pressure. As a result, the pickle liquid is uniformly injected regardless of the hard and soft parts of the raw meat mass, and the injection amount is kept uniform.

[0005] However, the hard and soft parts of the raw meat chunk such as ham are not clearly separated. Rather, the hardness gradually changes, and it is often unclear where the hard part is and where the soft part is. Further, it is common for there to be an intermediate portion between the hard and soft portions. Therefore, in the injector of the above publication,
When supplying the pickle liquid at a relatively high or low pressure, the problem is where to switch between high and low pressure. No matter where the high and low pressures are switched, it is not possible to inject the pickle liquid accurately, especially in the middle part.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems,
The hardness of the raw meat mass gradually changes, and the hard part of the raw meat mass,
The purpose of the present invention is to uniformly inject the pickle liquid regardless of the presence of an intermediate part and a soft part.

According to the present invention, the raw meat block is intermittently fed by the feed conveyor, and the raw meat block is intermittently fed with a unit stroke of about 1 / n times its length (where n is an integer of 3 or more). Is done. Further, a large number of injection needles are arranged above the feed conveyor, the pickle liquid is supplied to the injection needles, and at every intermittent feeding of the raw meat mass, the injection needle descends toward the raw meat mass and pierces the raw meat mass. Then, the pickle liquid is injected into the raw meat mass. further,
A pressure adjusting valve is provided in the supply path of the pickle liquid, and the supply pressure of the pickle liquid is adjusted by the pressure adjustment valve. Further, the program control device is connected to the pressure control valve, and while the raw meat mass is intermittently fed n times, the pressure control valve is program-controlled by the program control device for each intermittent feed, and the supply pressure of the pickle liquid is gradually reduced. Or it is gradually increased.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.

In FIG. 1, the injector has a number of injection needles 1. The injection needle 1 is for injecting the pickle liquid, extends vertically, is disposed above the feed conveyor 2, and is attached to the injection head 3. The feed conveyor 2 is for intermittently feeding the raw meat mass 4, and the raw meat mass 4 is a raw meat mass such as ham, and has a hard portion 4a, an intermediate portion 4b, and a soft portion 4c. L is approximately 600 mm. And
The raw meat block 4 is intermittently fed with a unit stroke S of about 1 / n times the length L (where n is an integer of 3 or more). In this embodiment, the raw meat block 4 is intermittently fed with a unit stroke S of 75 mm. Therefore, the raw meat chunk 4 is intermittently fed with a unit stroke S that is approximately 倍 times the length L thereof.

The injection needles 1 are arranged in the length direction and width direction of the feed conveyor 2. In this embodiment, as shown in FIG. 9, each injection needle 1 is arranged in three rows,
In the length direction of the feed conveyor 2, three injection needles 1 are arranged with a spacing C1 of 25 mm, and in the width direction of the feed conveyor 2, 22 injection needles 1 are arranged with a spacing C2 of 12.5 mm. It is placed and arranged.

Further, a pickle liquid supply pump is connected to the supply tube 5, and the supply tube 5 is connected to the injection head 3.
Between them, a pressure regulating valve 6 is provided in the supply channel of the pickle liquid. Therefore, the pickle liquid is supplied to the pressure control valve 6.
Through the supply tube 5, the pickling liquid is supplied to the injection head 3 and the injection needle 1. The pressure adjusting valve 6 is for adjusting the supply pressure of the pickle liquid.

Further, as shown in FIG. 10, the injection head 3 is fixed and supported on the upper end of the rod 7, and the rod 7 extends vertically and is inserted into the bush 9 of the frame 8,
It is guided to be able to descend and ascend. Further, an AC servomotor 10 is used as a drive mechanism of the injection needle 1, and the servomotor 10 is connected to the speed reducer 11 and the crank 1.
2, the crank 12 is connected to the link 13 and the connecting member 14, and the connecting member 14 is fixed to the lower end of the rod 7.

Therefore, the crank 12 is rotated by the servo motor 10 and the speed reducer 11,
And the connecting member 14 and the rod 7 by the link 13
Can be lowered and raised, whereby the injection head 3 and the injection needle 1 can be lowered and raised. The crank 12 rotates forward and backward over the set angle range, and the injection needle 1 descends to the set position and rises to the set position.

Further, a program controller 15 is connected to the pressure regulating valve 6 and the servomotor 10. The program control device 15 controls the pressure regulating valve 6 and the servomotor 10 in a program.

In this injector, when the raw meat chunk 4 is intermittently fed by the feed conveyor 2, the crank 12 is driven and rotated by the servomotor 10, and the injection needle 1 descends toward the raw meat chunk 4 and feeds. After the conveyor 2 stops, the injection needle 1 pierces the raw meat mass 4 and the pickle liquid is injected into the raw meat mass 4. Thereafter, the injection needle 1 is lifted from the raw meat mass 4 and extracted.
Further, thereafter, the raw meat block 4 is intermittently fed again, and the injection needle 1 is lowered again. This is sequentially and alternately repeated, and at every intermittent feeding of the raw meat chunk 4, the injection needle 1 descends toward the raw meat chunk 4, pierces the raw meat chunk 4, and the pickle liquid is injected into the raw meat chunk 4.

Furthermore, in this injector, when the raw meat chunk 4 is intermittently fed by the feed conveyor 2, the hard part 4a is arranged in the front and the soft part 4c is arranged in the rear. About 1 / L
The sheet is intermittently fed with an eight times unit stroke S. Therefore, the raw meat chunk 4 advances by the length L when it is intermittently fed eight times. And the raw meat chunk 4 is 8
During the intermittent feed, the hard part 4a, the middle part 4b and the soft part 4c gradually advance and reach the position of the injection needle 1 as shown in FIGS. Injection needle 1 pierces at 4a, intermediate portion 4b and soft portion 4c, respectively.
Pickle liquid is injected.

Further, in this injector, the supply pressure of the pickle liquid is programmed in advance in the program controller 15. Then, while the raw meat block 4 is intermittently fed eight times, the pressure control valve 6 is program-controlled by the program controller 15 for each intermittent feed, and the supply pressure of the pickle liquid is gradually reduced.

For example, when the raw meat lump 1 is at the position shown in FIG. 1, the pressure control valve 6 is program-controlled by the program controller 15 so that the supply pressure of the pickle liquid is 2.8 k.
g / cm ² . Thereafter, the raw meat block 4 is intermittently fed by the feed conveyor 2, and when it reaches the position shown in FIG. 2, the supply pressure of the pickle liquid is 2.7 kg / cm ^2.
It is adjusted to. Further, when the raw meat mass 4 is intermittently fed again and reaches the position shown in FIG. 3, the supply pressure of the pickle liquid is adjusted to 2.55 kg / cm ² , and the raw meat mass 4 is again intermittently fed. When reaches the position shown in FIG. 4, the supply pressure of the pickle liquid is adjusted to 2.4 kg / cm ² ,
When the raw meat block 4 is intermittently fed again and reaches the position shown in FIG. 5, the supply pressure of the pickle liquid is 2.3 kg / cm ^2.
It is adjusted to. Further, when the raw meat mass 4 is intermittently fed again and reaches the position shown in FIG. 6, the supply pressure of the pickle liquid is adjusted to 2.2 kg / cm ² , and the raw meat mass 4 is again intermittently fed. 7 reaches the position shown in FIG. 7, the supply pressure of the pickle liquid is adjusted to 2.1 kg / cm ² , the raw meat mass 4 is intermittently fed again, and when it reaches the position shown in FIG. The supply pressure is adjusted to 2.0 kg / cm ² .

Therefore, from 2.8 kg / cm ² to 2.
In the pressure range up to 0 kg / cm ² , the supply pressure of the pickle liquid is gradually reduced and the pouring liquid is injected into the raw meat chunk 4 every time the raw meat chunk 4 is intermittently fed. Accordingly, the hardness of the raw meat mass 4 gradually changes, and the raw meat mass 4 has a hard portion 4a, an intermediate portion 4b, and a soft portion 4c.
If there is, there is no problem. When the injection needle 1 pierces it, it is difficult to inject the pickle liquid in the hard part 4a, but the pickle liquid is supplied at a relatively high pressure.
As a result, the injection amount of the pickle liquid is adjusted, and the pickle liquid can be sufficiently injected. Conversely, in the soft part 4c, the pickle liquid is easily injected, but the pickle liquid is supplied at a relatively low pressure, whereby the injection amount of the pickle liquid is adjusted, and the pickle liquid is not excessively injected. Further, in the intermediate portion 4b, the pickle liquid is supplied at an intermediate pressure, whereby the injection amount of the pickle liquid is adjusted.

Further, in this injector, every time the raw meat chunk 4 is intermittently fed eight times, the next raw meat chunk 4 is placed on the feed conveyor 2 at a predetermined position of the feed conveyor 2, and thereafter, the feed conveyor 2 It is intermittently sent. Therefore, when the previous raw meat mass 4 has advanced by the length L and has passed the position of the injection needle 1, the hard part 4 a of the next raw meat mass 4 reaches the position of the injection needle 1. Then, the program control device 15
, The program is switched, and the supply pressure of the pickle liquid is adjusted to 2.8 kg / cm ² . Thereafter, similarly, while the raw meat mass 4 is intermittently fed eight times, the supply pressure of the pickle liquid is gradually decreased each time the raw meat mass 4 is intermittently fed, and the raw meat mass 4 is injected into the raw meat mass 4.

Therefore, even if the hardness of the raw meat mass 4 gradually changes and the raw meat mass 4 has a hard portion 4a, an intermediate portion 4b, and a soft portion 4c, the pickle liquid is uniformly injected regardless of the hardness. And the injection amount can be kept uniform.

Further, with respect to the descending speed and the ascending speed of the injection needle 1, the rotation speed of the crank 12 is programmed in advance in the program controller 15. While the raw meat block 4 is intermittently fed eight times, the servomotor 10 is program-controlled by the program controller 15 for each intermittent feed to gradually increase the rotation speed of the crank 12, thereby reducing the injection needle 1. The descending speed and the ascending speed can be gradually increased. Injection needle 1
Can be gradually increased, or only the ascending speed can be gradually increased.

In this case, when the injection needle 1 pierces the raw meat chunk 4, the pickle liquid is hard to be injected at the hard portion 4a, but the injection needle 1 descends or rises at a relatively low speed, and the injection needle 1 The time of sticking into the raw meat block 4 is long. As a result, the injection amount of the pickle liquid is adjusted, and the pickle liquid can be sufficiently injected. Conversely, in the soft part 4c, the pickle liquid is easily injected, but the injection needle 1 descends or rises at a relatively high speed, and the time during which the injection needle 1 sticks into the raw meat mass 4 is short. Thereby, the injection amount of the pickle liquid is adjusted, and the pickle liquid is not excessively injected.
Further, at the intermediate portion 4c, the injection needle 1 descends or rises at an intermediate speed, whereby the injection amount of the pickle liquid is adjusted.

Therefore, the hard part 4a of the raw meat mass 4
Irrespective of the intermediate portion 4b and the soft portion 4c, the pickle liquid can be injected uniformly, and the injection amount can be kept uniform.

The pressure control valve 6 is program-controlled by the program controller 15 to gradually reduce the supply pressure of the pickle liquid, and at the same time, the servomotor 10 is program-controlled by the program controller 15 to determine the lowering speed of the injection needle 1 or The rising speed may be gradually increased.

Further, when the raw meat block 4 is intermittently fed by the feed conveyor 2, the soft portion 4c
Is arranged forward, and the hard part 4a is arranged rearward. Then, while the raw meat chunk 4 is intermittently fed eight times, the pressure control valve 6 may be program-controlled by the program controller 15 for each intermittent feed to gradually increase the supply pressure of the pickle liquid. While the raw meat block 4 is intermittently fed eight times, the servomotor 10 may be program-controlled by the program controller 15 for each intermittent feed to gradually decrease the descending speed or the rising speed of the injection needle 1.

In this case, when the injection needle 1 pierces the raw meat mass 4, the pickle liquid is easily injected at the soft part 4c, but the pickle liquid is supplied at a relatively low pressure or the injection needle 1 It descends or rises at a relatively high speed. Thereby, the injection amount of the pickle liquid is adjusted, and the pickle liquid is not excessively injected. Conversely, in the hard part 4a, the pickle liquid is hardly injected, but the pickle liquid is supplied at a relatively high pressure, or the injection needle 1 moves down or rises at a relatively low speed.
As a result, the injection amount of the pickle liquid is adjusted, and the pickle liquid can be sufficiently injected. Further, in the intermediate portion 4b, the pickle liquid is supplied at an intermediate pressure, or the injection needle 1 descends or ascends at an intermediate speed,
Thereby, the injection amount of the pickle liquid is adjusted, and the same function and effect can be obtained.

In this embodiment, the raw meat chunk 4 is intermittently fed with a unit stroke S which is about 1/8 of the length L, but this is not always necessary. For example, the raw meat block 4 is intermittently fed with a unit stroke of about 1/4 or 1/6 of its length L. Then, while the raw meat block 4 is intermittently fed four or six times, the pressure control valve 6 is program-controlled by the program controller 15 for each intermittent feed, so that the supply pressure of the pickle liquid is gradually reduced or increased. Alternatively, the servomotor 10 may be programmed to increase or decrease the descending speed or the rising speed of the injection needle 1. The raw meat mass 4 is intermittently fed with a unit stroke of about 1/10 or 1/12 of the length L, and the raw meat mass 4
During the intermittent feed of 0 or 12 times, the pressure control valve 6 may be program-controlled by the program controller 15 at each intermittent feed to gradually decrease or increase the supply pressure of the pickle liquid. Control and
The descending speed or the rising speed of the injection needle 1 may be gradually increased or decreased. It is also conceivable to intermittently feed the raw meat mass 4 with other unit strokes.

In short, the raw meat chunk 4 is intermittently fed with a stroke of about 1 / n times the length L (where n is an integer of 3 or more), and while the raw meat chunk 4 is intermittently fed n times, At each intermittent feed, the pressure control valve 6 is program-controlled by the program controller 15 to gradually decrease or increase the supply pressure of the pickle liquid, or
, The descending speed or the rising speed of the injection needle 1 may be gradually increased or decreased.

It is also conceivable that the injection needle 1 is lowered and raised by another drive mechanism instead of the servomotor 10, and the program control unit 15 controls it by program.

As shown in FIG. 11, the injection needles 1 may be arranged in six rows instead of three rows. It is also conceivable to arrange the injection needles 1 in other rows.

[0033]

As described above, according to the present invention, even if the raw meat mass 4 has a hard part 4a, an intermediate part 4b and a soft part 4c, the pickle liquid is uniformly injected regardless of the parts. The injection amount can be kept uniform, and the intended purpose can be achieved.
