【Example】
Embodiments of the present invention will be described below with reference to the drawings. In the figure, F is a box-shaped slicer machine base, and A is a round-blade blade mounted on the upper side of a tool post (not shown) standing upright on one side of the machine base F with the rotation surface vertical. The cutter C is provided on the side (left side in the drawing) of the cutter A so as to be movable in the front-rear direction, and B is guided by a rail (not shown) provided on the upper surface of the machine base F. Also, a conventionally known meat box that reciprocates in the left-right direction in the figure along with the rotation of a crank (not shown). M is a material that is loaded into a meat box and sliced to a predetermined thickness while the cross-sectional area is measured.
[0009]
The contact plate C includes a pair of left and right guide shafts 1 provided in the lower portion and a central rack shaft 2. The pinion 3 is engaged with the rack shaft 2, and its operation is controlled by a servo motor 4 controlled by a control circuit (not shown). Driven and slidable in the front-rear direction.
[0010]
As shown in FIGS. 1 and 2, the backing plate C has an appropriate number of photoelectric sensors 5 arranged along the height direction of the meat box B at the side edge C ′ approaching the round blade A.
As shown in FIG. 1, each photoelectric sensor 5 is sensitive to the material M in the meat box B at every height in a process in which the meat box B located in front of the blade A moves back to the contact plate C side. It is turned on in the section sensitive to the presence of material, and turned off in the non-sensitive section, and the presence or absence of the material M passing through the installation height is detected.
[0011]
On the other hand, as shown in FIGS. 1 and 2, the meat box B has an endless belt in which a connecting member 6 provided at the lower part is stretched between a pair of left and right rotating shafts 7 and 8 along the reciprocating direction of the meat box. The travel position and distance are measured by an encoder 10 connected to 9 and attached to one rotary shaft 8.
[0012]
In this embodiment, the encoder 10 transmits one pulse each time the meat box B moves a unit length. Then, the control circuit of the contact plate C detects the height of the material in the meat box during the ON section detected by each photoelectric sensor 5 every time the meat box moves by the unit length , that is, each photoelectric sensor 5 detects. As shown in FIG. 1, the measurement result calculated by integrating the height of the material on the contour line representing the maximum outer shape of the material and the movement distance of the material in the meat box obtained from the number of pulse signals transmitted by the encoder 10 is obtained. A thickness signal which is input as a cross-sectional area of the material and is determined by comparison with preset parameters, weight setting values, etc. is output, the servo motor 4 is driven at a predetermined angle, and the contact plate C is moved to a predetermined position. .
[0013]
Each photoelectric sensor 5 is configured such that the front surface is opened and closed in conjunction with the reciprocation of the meat box B by a plate-like shutter 11 provided on the surface of the abutting plate C.
[0014]

The front and rear of the photoelectric sensor 5 are opened and closed.
[0015]
The shutter 11 covers the front surface of the photoelectric sensor 5 during the forward stroke of the meat box B and prevents the drip or the like leached from the material from adhering to the sensor 5. Further, the front surface of the photoelectric sensor 5 is opened during the return stroke so that the material area measurement by the sensor 5 is not hindered.
[0016]
As shown in FIG. 3, when the front surface of the photoelectric sensor 5 is closed, the shutter 11 is double-fitted with the side edge 19 ′ of the small cover 19 provided in front of the photoelectric sensor 5 so that the drip or the like is photoelectrically connected. Intrusion to the sensor 5 side is further prevented. Further, the side edge portion 19 ′ is provided with a vertical groove 19 ″ at the fitting portion with the shutter 11 so that the drip entering the fitting portion is discharged downward.
[0017]
FIG. 4 is a flowchart showing a series of operations of the slicer described above. As shown in the flowchart, when the material (meat lump) M is loaded on the meat box B and the meat box B is driven, the encoder 10 measures the travel position of the meat box B. When the meat box B reaches the measurement position, the shutter 11 opens, and at the same time, the contact plate C returns to the area measurement position. Then, the cross-sectional area measurement by the photoelectric sensor 5 in the backward stroke is started, the number of pulses of the encoder 10 in the sensitive section of the photoelectric sensor 5 is accumulated, and the area measurement is finished.
[0018]
When the area measurement result is input to a setting unit 18 having a target weight setting, parameter setting, area calculation, and stop signal input unit before the meat box, a meat feed amount signal and a shutter 11 closing signal are output from the unit 18. Then, the servo motor 4 of the backing plate C and the servo motor of the material feeding mechanism (not shown) are operated by the command of the control circuit 20 to feed the material in the meat box, and on the other hand, the backing plate C moved to the set position. After a predetermined amount of material M is fed out toward the head, cutting with the round blade A is performed as the meat box B is moved. In this way, quantitative slicing of meat chunks is realized.
[0019]
