  Generally, the raw meat chunk has a soft part and a hard part, a part with a lot of fat, a part with a small part, etc., and is not necessarily uniform throughout. Nevertheless, in the conventional example, the pickle solution is injected by inserting the injection needle uniformly. Therefore, for example, the injection needle is easy to stick in a soft part and the injection amount is large, and the injection needle is hard to stick in a hard part and the injection amount is small, so that the pickle liquid in the raw meat chunk is uneven. It becomes a distribution state.

  In view of the above circumstances, an object of the present invention is to make it possible to uniformly inject a pickle liquid into a raw meat chunk.

  A first embodiment of the present invention will be described with reference to FIGS. The pickle liquid injection injector 1 includes a conveying means 3 for a raw meat block (also referred to as “raw wood”) B and an injection passage 5 having a vertical center line C.

  The conveying means 3 includes a pair of hoppers 7 that accommodate the log B, a guide passage 8 that continues to the outlet of the hopper 7, and a lower end of the guide passage 8, that is, an upper end portion of the injection passage 5. Nipping rollers 10 and 10 are provided. The sandwiching roller 10 is a means for holding the log B, and for example, as shown in FIG. 5, a roller having a plurality of rotating needles 10a protruding at a predetermined interval in the circumferential direction is used. The roller 10 is driven by a motor 13, and its rotation shaft is fitted and supported by a bearing of the frame 11.

  The injection passage 5 is formed vertically below the sandwiching roller 10, but a pair of injection heads 15 and 15 are provided on both sides of the injection passage 5 so as to face each other. The upper and lower ends of the injection heads 15 and 15 are connected to the horizontal rods 17 and 19 and are slidably held. Both ends of the horizontal rods 17 and 19 are fixed to the frame 11 in parallel to each other.

  The injection head 15 has a pickle liquid supply pipe 21, a pickle liquid injection needle 23 communicating with the supply pipe 21, a through hole through which the injection needle 23 passes, and a pressing plate 25 that abuts against the side surface of the raw wood. And. The pressing plate 25 is connected to the injection head 5 via a spring. The injection heads 15 and 15 are slid in the horizontal direction by the sliding means, that is, the direction orthogonal to the center line C, and are separated from each other. The sliding means includes, for example, a wire 27 stretched between the injection head 15 and the frame 11, a sliding rod 29 connected to the center of the wire 27, and a servo that slides the sliding rod 29. And a drive source 31 such as a motor.

  A pair of sandwiching rollers 33 and 33 for feeding the log B are received at the lower end of the injection passage 5. As the sandwiching rollers 33, 33, for example, a roller having a rotating needle similar to the sandwiching roller 10 is used. The roller 33 is driven by a motor (not shown).

  Next, the operation of this embodiment will be described. As shown in FIG. 3, when the log B is dropped into the guide passage 8 from the hopper 7, the log B is lowered while being vertical, and is sandwiched between the pinching rollers 10 and 10, and the rotating needle 10a is bitten. Then, it moves downward while the movement amount (feed amount) is regulated by the sandwiching rollers 10, 10 and enters the vertical injection passage 15.

  When the rotation of the clamping rollers 10 and 10 is stopped after the log B is lowered by a predetermined distance, the log B is held by the rollers 10 and 10 and is suspended.

In this state, when the drive source 31 is driven and the slide rod 29 is slid, the wire 27 is displaced and the injection heads 15 and 15 are moved in a direction approaching each other (arrow A15 direction). The pressing plates 25 and 25 are pressed against both side surfaces B ₁ and B ₂ of the log B (see the chain line portion in FIG. 6). Therefore, the log B is in a state where the movement of the upper part B ₃ and both side faces B ₁ and B ₂ is restricted and fixed in the injection passage 5.

In this state, the injection needles 23 and 23 of the injection heads 15 and 15 rapidly move toward both side surfaces (thickness-direction surfaces) B ₁ and B ₂ of the log B, so that the pickle liquid is injected. . In this way, since the pickle liquid is injected from both side surfaces B ₁ and B _{2 of the} log B at the same time, the pickle liquid can be uniformly distributed.

Next, the drive source 31 is driven to return the injection heads 15 and 15 to their original positions. Then, since the pressing plates 25 and 25 are separated from the raw wood B in the injection passage 5, the restriction on both side surfaces B ₁ and B ₂ of the raw wood B is released (solid line portion in FIG. 6).

  Therefore, the nipping rollers 10 and 10 are rotated and the log B is lowered and stopped by a predetermined distance, and in this state, the pickling liquid is injected into the log B using the injection heads 15 and 15 as described above. The above process is repeated so that the pickle solution is evenly distributed over the whole log B (see FIG. 2).

  When the pickling liquid injection of the raw wood B in the injection passage 5 is completed, when the holding rollers 10 and 10 are rotated to release the holding of the raw wood B, the raw wood B falls, and the lower end of the raw wood B is for discharging during rotation. It is sandwiched between rollers 33, 33 (see FIG. 4). Therefore, the log B descends while its movement is restricted by the rollers 33, 33, is accommodated in a cradle (not shown), and proceeds to the next process.
