Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art For example, in the process of processing ham, a pickle liquid injection injector is generally used when injecting a pickle liquid into the raw meat mass. That is what is described in Japanese Examined Patent Publication No. 3-16098. In the injector of the same publication, a large number of injection needles are arranged above the feed conveyor, pickle liquid is supplied to the injection needles, and the feed conveyor intermittently feeds the raw meat chunks. Goes down to the raw meat mass. Therefore, the injection needle pierces the raw meat block and the pickle liquid is injected into the raw meat block.

By the way, in many cases, with regard to raw meat chunks such as ham, the raw meat chunk has a soft portion and a hard portion, and conventionally there has been a problem associated with that portion. For example, loin ham consists of ribs and loin, the ribs are soft and the loin is hard. Then, the injection needle pierces the rib and the loin, and the pickle liquid is injected into the rib and the loin, but it is natural that the injection conditions differ depending on the hardness of the raw meat, and with a soft rib, the pickle liquid is easily injected. , Its injection volume is large, and with hard loin,
The pickle solution is difficult to be injected, and the injection amount is small. Therefore, there is a problem that the pickle liquid cannot be uniformly injected.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems,
The purpose of the invention is to uniformly inject the pickle liquid regardless of the soft and hard parts of the raw meat.

[0005]

According to the present invention, the feed meat is intermittently fed by the feed conveyor, and when the raw meat chunk reaches a predetermined position, it is detected by the sensor. Furthermore, A
A feed conveyor drive, such as a C servo motor, drives the feed conveyor and a program controller is connected to the sensors and the feed conveyor drive. Then, based on the detection signal of the sensor, the feed conveyor drive mechanism is program-controlled by the program control device, and when the soft portion of the raw material chunk is at the position of the injection needle, the feed conveyor is driven with a relatively large feed stroke, The feed conveyor is driven with a relatively small feed stroke when the hard portion of the meat is at the position of the injection needle.

Alternatively, the injection needle drive mechanism, such as an AC servomotor, lowers and raises the injection needle and connects the program controller to the sensor and the injection needle drive mechanism. Then, based on the detection signal of the sensor, program control the injection needle drive mechanism by the program control device, when the soft portion of the raw material meat mass is at the position of the injection needle, lower or raise the injection needle at a relatively high speed, When the hard part of the raw meat is at the position of the injection needle, the injection needle may be lowered or raised at a relatively low speed.

A pressure adjusting valve is provided in the pickle liquid supply passage, and a program controller is connected to the sensor and the pressure adjusting valve. Then, based on the detection signal of the sensor, the program control device program-controls the pressure regulating valve,
Adjust the supply pressure of the pickle liquid with the pressure control valve, and when the soft part of the raw meat mass is at the position of the injection needle, supply the pickle liquid at a relatively low pressure, and the hard part of the raw meat mass is at the position of the injection needle. The pickling liquid may be supplied at a relatively high pressure.

Further, the raw meat piece is composed of a soft portion A and a hard portion B. Further, in this injector, the rotation angle of the crank 34 of the feed conveyor 2 is programmed in advance by the program control device 44, and when the raw material meat mass reaches a predetermined position, it is detected by the sensor 46, and its detection signal is detected. Is the program controller 44
Sent to. In this embodiment, when the starting end of the raw meat piece reaches the position of the sensor 46, the sensor 46 detects it. Then, based on the detection signal of the sensor 46,
The position of each part A, B is calculated by the program control device 44. Further, based on the calculated value, the AC servomotor 32 is program-controlled by the program controller 44, and when the soft portion A of the raw material chunk is at the position of the injection needle 1, the crank 34 rotates over a relatively large angular range. . Therefore, the feed conveyor 2 is driven with a relatively large feed stroke, and the movable plate 15 moves forward and backward with a relatively large feed stroke. On the contrary, when the hard portion B of the raw material chunk is at the position of the injection needle 1, the crank 34 rotates over a relatively small angular range, the feed conveyor 2 is driven with a relatively small feed stroke, and the movable plate 15 is compared. Move forward and backward with a small feed stroke.

Therefore, when the soft portion A of the raw meat is at the position of the injection needle 1, the raw meat is intermittently fed with a relatively large feed stroke, and the hard portion B is fed.
Is located at the position of the injection needle 1, the raw meat chunk is intermittently fed with a relatively small feed stroke. Then, at each intermittent feed, the injection needle 1 pierces the raw meat meat and the pickle liquid is injected into the raw meat meat. Therefore, in the soft part A, the pickle liquid is easily injected, but the raw meat chunk is intermittently fed with a relatively large feed stroke, and the piercing frequency of the injection needle 1 per unit length of the raw meat chunk and the injection of the pickle fluid. Infrequent. This adjusts the injection amount of the pickle liquid so that the pickle liquid is not excessively injected.
On the other hand, for the hard part B, the pickle solution is difficult to be injected, but the raw meat chunk is intermittently fed with a relatively small feed stroke, and the frequency of piercing of the injection needle 1 per unit length of the raw meat chunk and the pickle fluid Injection frequency is high. By this, the injection amount of the pickle liquid is adjusted, and the pickle liquid can be sufficiently injected.

Further, in this injector, in the program controller 44, the crank 4 of the injection needle 1 is
A rotation speed of 1 is pre-programmed. Then, based on the detection signal of the sensor 46, the AC servomotor 39 is program-controlled by the program control device 44, and when the soft portion A of the raw meat chunk is at the position of the injection needle 1, every intermittent feed of the raw meat chunk, Crank 4
1 rotates at a relatively high speed, and the injection needle 1 descends at a relatively high speed. On the contrary, when the hard part B of the raw meat is at the position of the injection needle 1, the crank 41 rotates at a relatively low speed and the injection needle 1 descends at a relatively low speed for each intermittent feed of the raw meat. To do. Instead, when the soft part A of the raw meat is at the position of the injection needle 1, the injection needle 1 is raised at a relatively high speed, and when the hard part B is at the position of the injection needle 1, the injection needle 1 Can also be raised at a relatively slow rate. When the soft part A of the raw meat is at the position of the injection needle 1,
Lowering and raising the injection needle 1 at a relatively high speed,
When the hard part B is at the position of the injection needle 1, the injection needle 1 can be lowered and raised at a relatively low speed.

Therefore, when the injection needle 1 is pierced into the raw meat mass, the pickle liquid is easily injected in the soft portion A, but the injection needle 1 descends or rises at a relatively high speed, and the injection needle 1 becomes the raw meat. The time to pierce the mass is short. This adjusts the injection amount of the pickle liquid so that the pickle liquid is not excessively injected. On the contrary, in the hard part B, the pickle liquid is difficult to be injected, but the injection needle 1 descends or rises at a relatively low speed, and the injection needle 1 pierces the raw meat chunk for a long time. By this, the injection amount of the pickle liquid is adjusted, and the pickle liquid can be sufficiently injected.

Furthermore, in this injector, the supply pressure of the pickle liquid is programmed in advance in the program control device 44. Then, based on the detection signal of the sensor 46, the pressure control valve 45 is program-controlled by the program control device 44, the supply pressure of the pickle liquid is regulated by the pressure control valve 45, and the soft portion A of the raw meat mass is adjusted to the injection needle 1. When in the position, pickle liquid is supplied at a relatively low pressure. On the contrary, when the hard portion B of the raw meat mass A is at the position of the injection needle 1, the pickle liquid is supplied at a relatively high pressure.

Therefore, when the injection needle 1 pierces the raw meat mass, the pickle liquid is easily injected at the soft portion A, but the pickle liquid is supplied at a relatively low pressure, whereby the injection amount of the pickle liquid is adjusted. Therefore, the pickle liquid will not be excessively injected. On the contrary, in the hard part B, the pickle solution is difficult to be injected, but the pickle solution is supplied at a relatively high pressure, whereby the injection amount of the pickle solution is adjusted and the pickle solution can be sufficiently injected.

Therefore, the pickle liquid can be uniformly injected regardless of the soft portion A and the hard portion B of the raw meat, and the injection amount can be kept uniform.

In this embodiment, when the soft portion A of the raw meat is at the position of the injection needle 1, the feed conveyor 2 is driven with a relatively large stroke to lower or move the injection needle 1 at a relatively high speed. It is raised and the pickle liquid is supplied at a relatively low pressure, so that the hard portion B of the raw meat mass
The feed conveyor 2 is driven with a relatively small stroke when the injection needle 1 is in the position, the injection needle 1 is lowered or raised at a relatively low speed, and the pickle liquid is supplied at a relatively high pressure. Was explained,
This is not always necessary. It is also conceivable that the injection amount of the pickle liquid is adjusted only by the feed stroke of the feed conveyor 2, the injection needle 1 is constantly lowered and raised at a constant speed, and the pickle liquid is always supplied at a constant pressure. It is also conceivable that the injection amount of the pickle liquid is adjusted only by the descending or raising speed of the injection needle 1, the feed conveyor 2 is always driven with a constant feed stroke, and the pickle liquid is always supplied at a constant pressure. It is also conceivable that the injection amount of the pickle liquid is adjusted only by the supply pressure of the pickle liquid, the feed conveyor 2 is always driven with a constant feed stroke, and the injection needle 1 is always lowered and raised at a constant speed. Feed stroke of feed conveyor 2, injection needle 1
The injection amount of the pickle liquid may be adjusted by any two adjusting elements of the descending or rising speed of the liquid and the supply pressure of the pickle liquid.

When B is at the position of the injection needle 1, the raw meat chunk is intermittently fed with a relatively small feed stroke. Furthermore, when the soft part A of the raw meat is at the position of the injection needle 1, the injection needle 1 descends or rises at a relatively high speed, and when the hard part B is at the position of the injection needle 1, the injection needle 1 is It descends or rises at a relatively low speed.
