  By the way, in the chop cutters of Patent Documents 1 and 2, a manual gripping portion is employed, and when the gripping portion is pierced into the frozen meat chunk, the operator presses the frozen meat chunk with the left hand. For this reason, there is little possibility that a frozen meat lump will float or shift.

  However, the chop cutter of Patent Document 3 employs an automatic gripping portion, and the automatic gripping portion cannot be driven unless the lid cover that closes the front opening of the meat box so as to be opened and closed is closed. Yes. That is, when piercing the gripping portion into the frozen meat chunk, the frozen meat chunk cannot be touched from the viewpoint of risk prevention.

  For this reason, in the chop cutter of Patent Document 3, when the claw-shaped grip portion is stabbed on the end side of the frozen meat chunk in the feed direction, depending on the shape of the frozen meat chunk, the starting end side of the frozen meat chunk in the feed direction is lifted or displaced. In some cases, the frozen meat chunk cannot be firmly gripped by the gripping part.

  If the frozen meat chunk is fed out toward the rotary blade as it is, there is a problem that the slice piece is uneven in thickness and cannot be commercialized. Further, since it is necessary to grip the frozen meat chunk again in order to avoid uneven thickness, there is a problem that the work efficiency is lowered by the work of gripping again.

  This invention makes it a technical subject to provide the chop cutter which improved after examining the above present conditions.

  The present invention comprises a meat box that contains a frozen meat chunk, a meat feed portion that feeds the frozen meat chunk toward a rotary blade provided in the meat box, and a gripping portion that grips the feed direction end side of the frozen meat chunk In addition to the grip portion, the chop cutter includes a pressing portion that presses the frozen meat chunk from above.

A double-acting gripping cylinder 42 in which a piston rod 43 protrudes downward is provided on the right end side of the box frame of the meat feeding portion 28. The gripping cylinder 42 is a pneumatic type. A midway portion of the gripping arm 38 is interlocked and connected to the piston rod 43 of the gripping cylinder 42 via a link arm (not shown). By the expansion and contraction of the piston rod 43 of the gripping cylinder 42, the gripping arm 38 rotates up and down via the link arm.

  When the gripping arm 38 is rotated downward by the extension movement of the piston rod 43 of the gripping cylinder 42, each claw 39 passes through the corresponding longitudinal slit and jumps outward from the left side plate portion of the meat feeding portion 28, and inside the accommodating portion 6. The claw 39 group is pierced from the upper side to the feed direction end side of the frozen meat block M. As a result, the frozen meat block M is gripped by the gripping arm 38 of the meat feed unit 28. When the gripping arm 38 is rotated upward by the shortening movement of the piston rod 43 of the gripping cylinder 42, each claw 39 passes through the corresponding longitudinal slit and is accommodated in the box frame of the meat feed unit 28. The gripping arm 38 of the meat feeding unit 28 constitutes a gripping unit that grips the end side in the feed direction of the frozen meat chunk M in the storage unit 6. A plurality of fixed auxiliary claws 45 pierced from the lower side to the feed direction end side of the frozen meat block M are arranged in the front-rear direction on the lower left outer side of the box frame of the meat feed unit 28.

  In the accommodating part 6 of the meat box 2, a pressing part 46 for the frozen meat block M is provided from above, separately from the gripping arm 38 of the meat feeding part 28. The pressing portion 46 is located above the meat feeding portion 28. The pressing portion 46 can reciprocate in parallel with the meat feed portion 28 between the initial position on the right end side of the housing portion 6 (see FIG. 11) and the pressing work position on the left side of the housing portion 6 (see FIG. 12).

  In the meat box 2, a pressing portion slide mechanism 47 is disposed between the housing portion 6 and the operation panel 18 (in front of the feed screw mechanism 29). The holding portion slide mechanism 47 includes a double-acting slide cylinder 48 in which the piston rod 49 protrudes to the right, and a guide that is positioned on both front and rear sides of the piston rod 49 of the slide cylinder 48 and extends in parallel with the piston rod 49. A pair of bars 50 and a pair of left and right sliders 51 fitted to the pair of guide bars 50 are provided. The slide cylinder 48 is of a pneumatic type. A left slider 51 is fixed to the distal end side of the piston rod 49 of the slide cylinder 48.

  The holding portion 46 in the housing portion 6 includes a pair of front and rear cross link mechanisms 54 that support and hold the press plate 53 that contacts the frozen meat block M from above on the concave frame 52 so as to be movable up and down, and both front and rear cross link mechanisms 54. And a double-acting lift cylinder 55 that lifts and lowers. The concave frame 52 is fixed to the front side of the pair of left and right sliders 51. In this case, a guide slot 8b having a shorter left and right length than the guide slot 8a is formed above the guide slot 8a in the back side plate 8 of the housing portion 6. The front side of the pair of left and right sliders 51 protrudes from the guide slot 8b of the back side plate 8 to the accommodating portion 6 side, and fastens the front side of the pair of left and right sliders 51 and the back side of the concave frame 52. By the expansion and contraction of the piston rod 49 of the slide cylinder 48, the pair of left and right sliders 51 and the concave frame 52 reciprocate in the left and right directions along the pair of guide bars 50. As a result, the pressing portion 46 reciprocates in the left-right direction between the initial position (see FIG. 11) and the pressing work position (see FIG. 12).

  The elevating cylinder 55 is a pneumatic type and is fixed to a recessed portion of the recessed frame 52. The piston rod 56 of the elevating cylinder 55 protrudes leftward into the concave frame 52, and a proximal end portion of a U-shaped slide body 57 arranged in the concave frame 52 on the distal end side of the piston rod 56. It is fixed to. In the concave frame 52, left and right guide bars 58 are fixed on both front and rear sides sandwiching the lifting cylinder 55.

The guide roller 62 is movable along the bowl-shaped plate portion 61. The other lower end side of the lower cross link 60 is pivotally attached to the corresponding bowl-shaped plate portion 61 so as to be rotatable.

  When the slide body 57 slides leftward due to the extension movement of the piston rod 56 of the elevating cylinder 55, the posture of the pair of front and rear cross link mechanisms 54 changes so that the upper and lower cross links 59 and 60 are raised. The holding plate 53 moves downward. When the slide body 57 slides to the right due to the shortening movement of the piston rod 56 of the elevating cylinder 55, the posture of the pair of front and rear cross link mechanisms 54 changes so that the upper and lower cross links 59 and 60 are laid down. The plate 53 moves up.

  Next, the pneumatic circuit and control structure of the chop cutter 1 will be described with reference to FIG. The pneumatic circuit 63 of the chop cutter 1 includes a gripping cylinder 42, a slide cylinder 48 and an elevating cylinder 55, and a compressor 64 that supplies high-pressure air to the cylinders 42, 48, 55.

The direction switching electromagnetic valve 65 has a pair of electromagnetic solenoids 66 electrically connected to a controller 67 that is a control means. The direction switching electromagnetic valve 65 is configured to extend the piston rods 43, 49, 56 of the cylinders 42, 48, 55 by the excitation of the electromagnetic solenoids 66 based on commands from the controller 67, and to move the piston rods 43, It is configured to switch and drive between a stop position where the operations of 49 and 56 are stopped and a shortened position where the piston rods 43, 49 and 56 are shortened.

  The controller 67 includes a rotary blade drive motor 25, a servo motor 36, a pair of electromagnetic solenoids 66 for each direction switching electromagnetic valve 65, a power switch 19 for turning on and off the entire power of the chop cutter 1, and a work for cutting off the frozen meat block M. A start switch 20 to start, a stop switch 21 to stop the cutting operation of the frozen meat block M, a grip arm up / down switch 22 to raise and lower the grip arm 38, an emergency stop switch 23 to forcibly stop the operation of each part of the chop cutter 1, A meat detection sensor 68 for detecting the presence or absence of the meat chunk M is connected. The meat detection sensor 68 is a transmissive or reflective photosensor in which a light emitting part and a light receiving part are arranged facing each other at a location near the side opening 12 in the accommodating part 6. In the chop cutter 1 according to the embodiment, when one of the left and right lid covers 3 and the carry-out cover 14 is opened while the frozen meat block M is being cut off, the chops such as the rotary blade 10 and the meat feed unit 28 are used. Each part of the cutter 1 is set to stop operating.

  Next, the frozen meat block M cut-off control by the chop cutter 1 will be described with reference to the flowchart of FIG. Note that the algorithm shown in the flowchart disclosed below is stored in advance in the ROM of the controller 67 as a program, and is read by the RAM and then executed by the CPU. Here, it is assumed that the frozen meat block M has been put in the storage unit 6 in advance, the left and right lid covers 3 and the carry-out unit cover 14 are all closed, and the power switch 19 is turned on. At this stage, the meat feeding unit 28 is in the storage position, and the pressing unit 46 is in the initial position (see FIG. 11).

  As shown in the flowchart of FIG. 10, when the start switch 20 is turned on (S01: YES), the slide cylinder 48 of the presser part slide mechanism 47 is shortened, and the presser part 46 is moved from the initial position to the presser work position. (See S02, FIG. 12). Next, the elevating cylinder 55 extends and the presser plate 53 moves downward through the pair of cross link mechanisms 54 to come into contact with the frozen meat block M from above (S03, see FIG. 13). In this case, the elongating operation of the elevating cylinder 55 may be continued so as to keep pressing the frozen meat block M with the pressing plate 53, or the elongating operation of the elevating cylinder 55 may be stopped to position the pressing plate 53. You may control to hold | maintain. Next, the gripping cylinder 42 of the meat feed unit 28 extends and the gripping arm 38 rotates downward, and the claw 39 group is pierced from above at the end of the frozen meat block M in the feed direction. That is, the frozen meat block M is gripped by the gripping arm 38 of the meat feed unit 28 (S04, see FIG. 14). Thus, according to the embodiment, the frozen meat block M can be pressed from above by using the pressing portion 46 when the gripping arm 38 grips the feed direction end side of the frozen meat block M. For this reason, regardless of the shape of the frozen meat chunk M, the floating meat chunk M can be reliably prevented from being lifted or displaced. As a result, even if it is the automatic gripping arm 38, the frozen meat block M can be securely gripped by the gripping arm 38, and unevenness of the thickness of the slice piece S can be prevented. The work of re-gripping is unnecessary, and the problem of reduced work efficiency can be avoided.

  Then, the elevating cylinder 55 is shortened and the presser plate 53 is moved upward through the pair of cross link mechanisms 54 to leave the frozen meat block M (see S05, FIG. 15). Then, the slide cylinder 48 of the presser part slide mechanism 47 extends and the presser part 46 retreats from the pressing work position to the initial position (S06, see FIG. 16). Next, the servo motor 36 is driven to rotate forward, and the meat feed unit 28 moves from the accommodation position toward the feed end position by a predetermined amount (for example, about the thickness of the slice piece S), and the frozen meat block M is moved to the rotary blade 10 ( Push out toward the side opening 12) of the case body 9 (S07). Next, when the meat detection sensor 68 detects the frozen meat block M (S08: YES), the rotary blade drive motor 25 is driven to rotate, and the rotary blade 10 rotates within the case body 9, and the frozen meat block M begins to feed in the feed direction. The slice pieces S are continuously cut off from the side, and the slice pieces S are accumulated in the carry-out part 13 (see S09, FIG. 17). Thereafter, when the meat feed unit 28 moves to the feed end position (S10: YES, see FIG. 18), the servo motor 36 is driven in reverse to return the meat feed unit 28 to the storage position, and the meat detection sensor 68 is set to the frozen meat block M. Is no longer detected, the rotation of the rotary blade 10 by the rotary blade drive motor 25 is stopped, and the frozen meat block M cutting operation is completed.

  19 to 22 show other examples of the attachment structure of the pressing portion 46. In the embodiment described above, the pressing portion 46 is movable between the initial position and the pressing work position. However, the present invention is not limited to this. For example, as shown in FIG. The pressing part 46 may be fixedly provided above, or the pressing part 46 may be fixedly provided in the vicinity of the pressing work position of the back side plate 8 in the accommodating part 6 as shown in FIG. In the example shown in FIG. 20, it is also possible to configure the pressing portion 46 so that it can protrude from the back side of the back side plate 8. Further, the pressing portion 46 may be configured to be pressed in conjunction with the downward rotation of the grip arm 38. In this case, it is preferable that the operation of the pressing portion 46 be performed at the same time as or in priority to the downward rotation of the grip arm 38. As shown in FIG. 21, a pressing portion 46 may be fixedly provided on the inner surface side of the left lid cover 3. Furthermore, as shown in FIG. 22, a manual pressing portion 46 may be employed. In this case, an operating rod portion 69 protruding upward from the holding plate 53 penetrates the left lid cover 3. A compression spring 70 is fitted on the operation rod portion 69, and the pressing plate 53 is configured to retreat upward by the elastic restoring force of the compression spring 70 when the operator releases the hand.

  The present invention is not limited to the above-described embodiment, and can be embodied in various forms. For example, the actuator for operating each part of the chop cutter 1 may employ various types such as a pneumatic cylinder or an electric motor. In addition, the structure of each part is not limited to embodiment of illustration, A various change is possible in the range which does not deviate from the meaning of this invention.
