Description

  The present invention relates to a meat processing machine, and more particularly to a meat processing machine capable of efficiently cutting pork streaks of a material when cooking tonkatsu.

When cooking tonkatsu, it was necessary to slice the pork of the material to a certain thickness and then cut the muscles inside the meat. The operation of cutting the muscle can be performed by cutting the tip of the knife into the meat. However, since it is inefficient when processing a large amount, the conventional “meat softening machine” described in Patent Document 1 is used. ”Etc. were used. This was achieved by efficiently cutting the streaks in the meat piece by lowering the blade with many blades suspended at appropriate intervals by operating the handle and piercing it into the meat piece placed under the blade.
Japanese Utility Model Publication No. 56-18079

  The “meat softening machine” described above is efficient because it can simultaneously process a plurality of pieces of meat arranged on a table. However, since the power is a human arm and the operator is fatigued when continuously operated, it is not suitable for a large amount of processing. Further, during processing, a piece of meat stuck into the blade that has been lowered may stick to the blade edge and rise together when the blade is raised and returned, and workability is not good. Therefore, the present invention proposes a meat processing machine that eliminates fatigue of an operator when processing a large amount and prevents the processed meat pieces from adhering to the blade and reducing workability. It was aimed.

In order to solve the above-described problems, the present invention provides a tool post in which a thin plate-shaped tool having a blade formed at the lower end is vertically suspended at an appropriate interval in the vertical and horizontal directions, and a tool rest that supports the tool rest to be movable up and down. A support mechanism; a tool post drive mechanism for driving the tool post to move up and down; a plurality of guide plates disposed below the tool post and vertically movable between the tools; and the guide plate can be moved up and down. And the guide plate support mechanism for supporting the guide plate, the lifting phase of the guide plate is delayed from the lifting phase of the tool post, and the first half of the rising stroke of the tool post and the second half of the lowering stroke of the guide plate are matched, A guide plate driving mechanism that drives the guide plate up and down so that the lower end of the guide plate is lower than the lower end of the tool, from the middle of the ascending stroke of the tool post to the middle of the lowering stroke of the tool post ; Machining arranged below the tool post and the guide plate And a stand .

Here, it is preferable that the phase of the lifting / lowering operation of the guide plate by the guide plate driving mechanism is delayed by approximately 90 degrees with respect to the lifting / lowering operation of the tool rest by the tool post driving mechanism.
Moreover, it is preferable to provide an elevating mechanism on the processing table so that the height of the processing table can be adjusted.

  As described above, according to the present invention, by providing the tool post driving mechanism for moving the tool post up and down, the burden of labor on the operator is reduced, and a large amount of continuous meat processing becomes possible. In addition, a guide plate is placed between the tool rests, and after the tool rest descends and cuts, when the tool rests, the guide plate is lowered to attach the processed meat to the tool. Can be prevented, and workability is improved. Furthermore, the present invention enables the internal streaks to be reliably cut even with a custom-made tonkatsu having a thickness several times that of a normal tonkatsu.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 is a front view of a meat processing machine according to the present invention, FIG. 2 is a right side view of FIG. 1, FIG. 3 is an enlarged sectional view taken along line AA of FIG. 1, and FIG. It is a BB sectional view taken on the line. As shown in FIGS. 1 and 2, two slide shafts 2, 3 are erected in a gate shape on the left and right sides of the front end of the upper surface of the base 1, and the upper ends thereof are connected to the bar 4. The slide shafts 2 and 3 are respectively fitted with slide bushes in two upper and lower stages, a stay 5 is placed on the upper slide bush, and a stay 6 is placed on the lower slide bush.

  Rods 11 and 12 are connected to both ends of the stay 5 via rod end bearings 7 and 8. The lower ends of the rods 11 and 12 are connected to crank mechanisms 14 and 15 provided at both ends of the drive shaft 13. Similarly, rods 18 and 19 are connected to both ends of the stay 6 via rod end bearings 16 and 17. The lower ends of the rods 18 and 19 are connected to crank mechanisms 14 and 15 provided at both ends of the drive shaft 13. The drive shaft 13 is belt driven by the motor 21 and rotates, whereby the rods 11 and 12 and the rods 18 and 19 connected to the crank mechanisms 14 and 15 are driven up and down. A flywheel 22 is attached to the drive shaft 13.

  As shown in FIGS. 3 and 4, a tool rest 24 in which a large number of thin plate-like blades 23 each having a blade formed at the lower end are suspended at appropriate intervals is provided below the central portion of the stay 5. The knobs 28 and 29 are detachably attached via 25 and 26. The cutters 23 are arranged at equal intervals in parallel with the longitudinal direction of the stay 5, and the cutters 23 are arranged in eight rows at equal intervals and supported by the tool rest 24. Nine guide plates 31 are disposed between the rows of the blades 23 and on both outer sides so as to be movable in the vertical direction. These guide plates 31 are attached to the stay 6 by attachment plates 32 to 35. These guide plates 31 are preferably plastic plates because they may be removed and washed.

Further, a processing table 38 is supported on the upper surface of the base 1 below the blade 23 via level adjusting screws 36 and 37. A cutting board 39 is placed on the processing table 38 so as to be movable in the front-rear direction, and the pork M sliced into a predetermined thickness is arranged on the cutting board 39.
Next, the usage method of the meat processing machine comprised in this way is demonstrated. Since the blade 23 and the guide plate 31 are supported by the stay 5 and the stay 6, respectively, when the motor 21 is activated, the crank mechanisms 14 and 15 repeat the lifting operation. At this time, the stay 6 is set to follow the raising / lowering operation of the stay 5 with a delay of about 90 degrees.

In this state, after arranging the pork M on the cutting board 39, the pork M is moved on the processing table 38 in the front-rear direction, and the pork M is moved below the blade 23 while the blade 23 and the guide plate 31 are raised. And hold that position. Then, first, blade 23 is lowered pierce pork M, when starting to rise again, the guide plate 31 to follow the phase lag of approximately 90 degrees and downward with a delay by approximately 90 degrees with respect to tool 23, tool The pork M pierced by 23 is pushed back downward, and the pork M is prevented from adhering to the blade 23 and rising.

Next, while the guide plate 31 is raised and both the blade 23 and the guide plate 31 are raised, the cutting board 39 is moved, and the raw pork M is moved below the blade 23. By repeating these operations, the blade 23 is penetrated through the pork M, and the internal muscles are cut. In addition, when it is desired to cut the muscle in the pork M more finely, the pork M can be turned over and processed from the opposite direction. Furthermore, it is possible to repeat these processings twice or more.

FIG. 5 is an explanatory view showing fluctuations in the positions of the lower ends of the blade 23 and the guide plate 31. The guide plate 31 follows the blade 23 with a delay of about 90 degrees. In the figure, the first half of the ascending stroke of the blade (upwardly rising section of the graph) and the second half of the descending stroke of the guide plate (downwardly extending section of the graph) overlap. In addition, the lower end of the guide plate is lower than the lower end of the blade during the middle of the upward stroke of the blade to the middle of the downward stroke of the blade. Further, the stroke of the guide plate 31 is smaller than the stroke of the blade 23, and the lowest position of the guide plate 31 is located above the lowest position of the blade 23. The difference t between the lowest position of the guide plate 31 and the lowest position of the blade 23 is the thickness of the pork M that can be processed by the meat processing machine. However, if the front and back surfaces of the pork M are separately processed, the thickness can be processed up to twice the difference t.

6 to 8 are enlarged views showing the shape of the tip of the blade 23. The blade 23A shown in FIG. 6 has a flat tip shape. The blade 23B of FIG. 7 has an inclined tip shape. The blade 23C in FIG. 8 has an M-shape with a center portion set back at the tip. These blades 23A to 23C are single blades in which one side of the tip is deleted obliquely, but it is also possible to use double blades in which both sides are deleted diagonally.

  The present invention can be used not only for cutting pork streaks for tonkatsu but also for cutting beef streaks for steak.
