Description

  The present invention relates to a pickle liquid injection injector that injects a liquid material such as a pickle liquid or seasoning liquid into a meat mass such as pork, beef, or poultry meat. More specifically, the meat mass being conveyed is turned over. The present invention relates to a pickle liquid injection injector provided with a front / back reversing device.

  Products such as ham, sausage and bacon are required to have a uniform taste throughout the product. Thus, conventionally, a predetermined amount of pickle liquid and seasoning are injected into meat chunks such as pork, beef and poultry meat, which are the raw materials of the product, using a pickle liquid injection injector (for example, Patent Document 1). ,reference). In this injector, an injection head having a large number of injection needles is disposed above a feed conveyor (belt conveyor), and when the raw meat chunk transported by the conveyor reaches directly below the injection head, While temporarily stopping, the injection head is lowered rapidly, the injection needle is inserted into the raw meat chunk, and the pickle liquid is injected.

Japanese Patent Application Laid-Open No. 6-209663

  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.

  The present invention relates to a pickle liquid injection injector comprising a conveyor for conveying raw meat chunks, and injection heads disposed upstream and downstream above the conveyor, the upstream injection head and the downstream injection head. A front / back reversing device for turning the raw meat chunk upside down is provided.

  The conveyor according to the present invention includes an upstream conveyor and a downstream conveyor which are independent from each other. The front and back reversing device is provided between the upstream conveyor and the downstream conveyor, and reverses the plate-shaped holding unit that supports the raw meat chunk into which the pickling liquid is injected by the upstream injection head. And a drive unit. The front / back reversing device includes a rotating arm that is disposed above the conveyor and sandwiches the tip of the raw meat chunk into which the pickling liquid has been injected by the upstream injection head, and a drive unit that rotates the rotating arm. It is characterized by. An upstream side of the front / back reversing device according to the present invention is provided with a device for forcibly moving raw meat chunks.

  Since the present invention is configured as described above, the raw meat chunk on the conveyor is pierced by the injection needle of the upstream injection head from the surface side and injected with the pickle liquid, and then turned upside down by the front / reverse inversion device. The back side faces upward, and in this state, the injection needle of the downstream side injection head is inserted and the pickle liquid is injected. Therefore, since the pickling liquid is injected into the raw meat chunk from the front surface and the back surface, the pickling liquid can be uniformly distributed as compared with the conventional example.

It is a front view which shows 1st Embodiment of this invention. It is a principal part enlarged view of FIG. It is a front view which shows 2nd Embodiment of this invention.

  A first embodiment of the present invention will be described with reference to FIGS. A pre-stage conveyor 1 and a post-stage conveyor 3 that convey the raw meat chunk B are arranged in series at intervals. Each of the conveyors 1 and 3 is a belt conveyor, and a plurality of injection needles are provided on the upper part thereof, and injection heads 5 and 6 are provided. On the downstream side of the injection heads 5 and 6, tender heads 8 and 9 having a cast block are provided.

  Between the front conveyor 1 and the rear conveyor 3, a front / back reversing device 10 is disposed. The front / back reversing device 10 includes a plate-like holding unit 11 that supports the raw meat block B, and a rotating shaft 13 that reverses the plate-like holding unit 11. The plate-like holding part 11 is formed in an L-shaped cross section, and is inclined obliquely upward toward the rear end 1A side of the front conveyor 1, and its front end part 11a is close to the rear end 1A of the front conveyor. Yes.

  The plate-like holding part 11 is connected to the rotating shaft 13 via the arm part 11b. The rotary shaft 13 is disposed at substantially the same height as the rotary shafts 1R and 3R of the conveyors 1 and 3, and is connected to a motor (not shown). The rotary shaft 13 is provided on the rotary shaft 3R side. The plate-like holding part 11 can be positioned above the rear conveyor 3 when the plate-like holding part 11 is reversed.

  Above the vicinity of the rear end 1 </ b> A of the front conveyor 1, a forced movement device 15 for the raw meat block B is provided. The forced movement device 15 includes a drive unit 15a fixed to the frame 14, and a pair of rollers 15a and 15b that are rotated by the drive unit 15a and supported in a vertically movable manner.

  In the figure, 17 is a raw material supply device, 19 is a pickle liquid flow path, 20 is a drive motor for the front injection head, 21 is a front tender drive cylinder, 22 is a drive motor for the rear injection head, 23 is an open / close door, and 24 is A rear-stage tender drive cylinder, 25 is a hydraulic pump drive motor, and 26 is a carry-out chute.

  Next, the operation of this embodiment will be described. When the raw material mass B supplied from the raw material supply device 17 onto the front stage conveyor 1 reaches just below the front stage injection head 5, the conveyor 1 temporarily stops and the injection head 5 suddenly descends so that the raw material mass B An injection needle is inserted from the surface of the surface to inject pickle liquid.

  When the injection of the pickle liquid is finished, the injection head 5 rapidly rises and the front conveyor 1 starts to advance. And when the front-end | tip part of the said raw meat block B reaches | attains the forced moving apparatus 15, it is made to advance suddenly compulsorily so that it may be drawn into the rotating rollers 15b and 15c.

  Thereafter, when the rear end portion of the raw meat chunk B is separated from the roller 15c and the entire raw meat chunk B is placed on the plate-like holding portion 11, a pressure sensor (not shown) attached to the roller 15c is activated. Then, a placement signal is sent to a control unit (not shown). Instead of the pressure sensor, a position detection sensor may be provided to check the rear end portion of the raw meat block B.

  The controller starts a drive motor (not shown) of the rotating shaft 13 and rapidly rotates the rotating shaft 13 by a predetermined angle. The rotation of the rotating shaft 13 is performed at a speed that does not cause the raw meat block B on the plate-like holding unit 11 to fall, but is appropriately selected as necessary. For example, the speed of the conveyors 1 and 3 is 0.035 m / sec. In this case, a rotation speed that makes a half rotation in 2.5 seconds is employed.

Then, since the plate-like holding part 11 is reversed and displaced above the rear conveyor 3, the raw meat block B is turned over and falls onto the rear conveyor 3 by its own weight.
When the rotation shaft 13 rotates by a predetermined rotation angle, the control unit reverses the rotation axis by the same rotation angle as the rotation speed, so that the plate-like holding unit 11 is returned to the original state.

  The raw meat block B1 on the rear conveyor 3 that is turned upside down is further conveyed forward, and the pickle liquid is injected from the rear surface side thereof by the rear injection head 6. Therefore, since the injection meat is injected into the raw meat chunk B1 from the front surface side and the back surface side and the pickle liquid is injected, the pickle liquid can be uniformly distributed and injected.

A second embodiment of the present invention will be described with reference to FIG. 3. The same drawings as FIG. 1 and FIG. 2 have the same names and functions. The main differences between this embodiment and the first embodiment are as follows.
(1) The conveying conveyor is formed by a single belt conveyor 30 instead of the two preceding and following conveyors 1 and 3.

  (2) The raw meat chunk front / back reversing device 10 is provided with a claw portion 31 for sandwiching the leading end of the raw meat chunk instead of the plate-like holding portion 11 on which the raw meat chunk is placed. The claw portion 31 is provided at the tip of the rotary arm 35 and is constituted by the fixed claw 12 a and the movable claw 31 b. The movable claw 31 b is moved up and down by the claw sliding portion 40. A base end portion of the rotary arm 35 is connected to a rotary shaft 33, and the rotary shaft 33 is rotated by a drive motor 41, which is controlled by a control unit 42.

  In this embodiment, the raw meat chunk B on the belt conveyor 30 into which the pickle liquid has been injected by the pre-injection head 5 is conveyed toward the claw portion 31 of the front / back reversing device 10, and the leading end B0 is connected to the fixed claw 31a. It enters between the movable claws 31b and presses the rotary arm 35 (see the claw portion 31 in FIG. 3).

  Then, since the rotary arm 35 is separated from the first contact sensor 37, the first contact sensor 37 sends a separation signal to the control unit 42 and the movable claw 31 b is lowered by the sliding of the claw sliding unit 40. Therefore, since the movable claw 31b presses the surface of the raw meat chunk B, the raw meat chunk B is clamped by the claw portion 31 (see the claw portion 31A in FIG. 3).

  In this state, the control unit 42 sends a reversal command to the drive motor 41, so that the rotary arm 35 rotates downstream. Then, since the claw portion 31 gradually moves away from the belt conveyor 30, the leading end portion B0 of the raw meat chunk B is gradually lifted higher (see the claw portion 31B in FIG. 3).

  Further, when the rotating arm 35 rotates in the same direction, it contacts the second contact sensor 39 and sends a contact signal to the control unit 42, and the movable claw 31b rises due to the sliding of the claw sliding unit 40, Since it leaves | separates from the raw meat chunk B, the said nail | claw part 31 is open | released (refer FIG. 3 claw part 31C). Therefore, the raw material meat block B in a vertical state is turned over and falls onto the belt conveyor 30 and is conveyed downstream.

  When the control unit 42 receives the contact signal from the second contact sensor 39, the control unit 42 reverses the rotation shaft 33, but rotates the rotation shaft 35 at the same speed as the rotation speed. , Returned to the original state.

  The pickled liquid is injected into the raw meat block B1 on the rear conveyor 3 from the back surface on the upper side by the downstream injection head 6 during the conveyance. Therefore, since the injection meat is injected into the raw meat chunk B1 from the front surface side and the back surface side and the pickle liquid is injected, the pickle liquid can be uniformly distributed and injected.

"Other embodiments"
The apparatus for reversing the front and back of the raw meat chunk of the present invention is not limited to the above, and in short, any means can be used as long as the raw meat chunk can be turned over between the front injection head and the rear injection head. For example, an inclined belt conveyor is disposed between the front belt conveyor and the rear belt conveyor, the rear end of the inclined belt conveyor is located below the rear end of the front belt conveyor, and the front end thereof is the rear belt conveyor. It may be made substantially the same as the position of the rear end so that the raw material lump falling from the front belt conveyor is turned over and put on the inclined belt conveyor, and transferred to the rear belt conveyor in this inverted state.
