JP 2003-136508 A

  However, it is difficult to bite the toes into hard frozen meat unless a large force is applied to the grip portion 22 for rotating the claw member 21 to press the meat log M. In addition, the tip of the toe once bitten into the frozen meat is softened near the toe due to the vibration of the raw meat during cutting, the meat holding function is loosened, and the thickness of the slice that the meat raw wood M moves at the cutting destination and cuts It may become uneven.

Therefore, the present invention has been made in order to solve the above-described problems, and it is easy to bite the toes into hard frozen meat. Provided is a chop cutter in which a frozen portion is melted and a meat pressing function is loosened, and the raw wood M is moved at a cutting destination and the thickness of a section to be cut is not uneven.
First, the invention according to claim 1
The meat log is provided with a gripping part including a contact plate that contacts the meat log, a claw member that pierces the meat log, and a pressure unit that presses the claw member against the meat log and pierces the meat log. In the chop cutter that conveys in the direction of the jade-shaped blade and cuts a piece of meat of the desired thickness with the jade-shaped blade,
The chop cutter is characterized in that an actuator is provided in the pressurizing portion, the claw member is pierced into a raw log, and the actuator is controlled so that a constant pressure is held on a claw tip of the claw member.
Thereby, since the pressurizing part is provided with the actuator, the claw member can be reliably pierced even if the meat log is hard and frozen. In addition, since the actuator is controlled so that a constant pressure is maintained on the toe of the claw member, even if the frozen meat on the toe melts and loosens, the nail portion is further pierced and the predetermined pressure is maintained in the pierced state. Since the actuator is actuated until the end of the operation, the section to be cut by always piercing the toe which is being thawed is always provided with a predetermined thickness.
Here, an air cylinder is optimal as the actuator because it handles food.

In the invention according to claim 2,
The actuator causes the claw member to pierce the meat log by any start command issued from a manual start switch or from a detector that detects that the lid cover that covers the top of the table on which the meat log is placed is closed. The chop cutter according to claim 1.
As a result, if the lid cover is not closed, the actuator will not operate and the claw part will not pierce, so it is safe.However, if it is difficult to hold it directly with the claw member due to the warpage of the meat log or the inclination of the end of the meat log to be pierced, etc. The operator needs to operate the actuator while holding down the meat log. In this case, the manual switch is operated as appropriate after switching by the switch for operating the manual switch regardless of the detection of the lid cover. In this case, when switching to operate the manual switch, an infrared detector etc. is installed near the pressurization part so that the position of the operator's hand attached to the raw log can be confirmed. It is desirable not to execute the operation command by the manual switch if it is detected that the value is inappropriate.
In the above, the operation of the manual start switch and the detector for detecting the opening / closing of the cover is shared by a changeover switch in one chop cutter. However, for a chop cutter without a cover, manual start In the case of a chop cutter that only has a switch and there is no variation in the shape of the raw meat logs or a separate member that presses the raw meat logs in the middle, etc., even if only starting with a detector that detects the opening and closing of the lid cover Good.

Next, the invention according to claim 3 is
It has a gripping part comprising a contact plate that comes into contact with the meat log placed on the mounting table, a claw member that pierces the meat log that has come into contact, and a pressure part that presses the claw member against the meat log and pierces it. In the chop cutter that conveys the meat log in the direction of the jade-shaped blade and cuts a piece of meat with a desired thickness with the jade-shaped blade,
The mounting table is provided so as to be able to move to the outside of the apparatus main body from the conveying position in the direction of the jade-shaped blade, and the work of supplying the meat logs to the mounting table can be performed on the outside of the apparatus main body, and the meat logs are supplied. The mounting table is a chop cutter that returns to a conveying position in the direction of the slanted blade.
Here, as the direction in which the mounting table moves from the transfer position in the direction of the jade-shaped blade to the outside of the apparatus main body, there is a drive member of the gripping unit, etc. It is not a side but a standing position side for an operator to perform a normal operation, and is a horizontal direction or an obliquely downward direction from a conveying position in the direction of a slanting blade. As a result, conventionally, since only the upper part of the mounting table is open, the meat log is lifted higher than the outer frame of the apparatus main body and then lowered to the mounting table. Since the pedestal moves, there is no need to lift heavy meat logs even at the height of the outer frame. In addition, the mounting table is open on both sides of the conveying direction to the jade-shaped blade so that the gripping part moves at the conveying position in the direction of the jade-shaped blade and does not obstruct the transport of the meat log in the direction of the blade. If the belt conveyor for supplying the meat logs at the same or almost the same height as this is provided at the end opposite to the blade direction of the mounting table moved to the outside of the apparatus main body, It becomes possible to transfer to the mounting table at that height, and the supply work of raw meat becomes easier. In particular, in the case of moving obliquely downward from the conveying position in the direction of the jade-shaped blade, the position of the mounting table is further lowered, and the supply work of the meat raw wood can be easily performed.
Moreover, as a locus | trajectory to which a mounting base moves, there are a case where it moves linearly from the conveying position in the direction of the slanting blade using the slide rail to the outside of the apparatus body, or a case where it moves in a curved line by an arm. When moving in a curved line by the arm, the mounting table fixed to the arm is the mounting table at the position where the arm is rotated and moved to the outside of the apparatus body by the angle of the opening at the transfer position in the direction of the slanting blade. Therefore, the angle at the position moved outward can be set to be an angle at which the meat log is easily placed. In addition, if the bottom surface of the mounting table is attached so that the left side is inclined downward in the conveying direction toward the jade-shaped blade, or the standing position side of the worker is inclined downward, Since it is positioned and cut on the left side surface or the standing side surface, it cuts away when it is cut into a lenticular blade with a pivot shaft attached to the right side in the conveying direction toward the deciduous blade direction. There will be no problems that will be uneven.
Furthermore, the chop cutter according to claim 3 can be used as a chop cutter for manually piercing the meat log with the claw member of the gripping part, and the apparatus main body from the conveying position in the direction of the deciduous blade by automation. A step of moving outward (Claim 3), a step of supplying one meat log by driving a belt conveyor to the mounting table, a step of returning the mounting table to its original position (Claim 3), and the meat of the mounting table It can also be used for a chop cutter in which the process of starting cutting by piercing a raw wood with a claw member of a gripping part (Claim 1) can be performed, and labor saving and unmanned work can be realized.

The invention according to claim 4
The carrying end of the mounting table moved to the outside of the apparatus main body from the conveying position in the direction of the jade-shaped blade is closed at the conveying end in the direction of the jade-shaped blade, and the supplied meat log is the conveying end in the direction of the jade-shaped blade A stop member for preventing the drop from falling, and when the mounting table is returned to the transfer position in the direction of the jade-shaped blade, the stop member opens the transfer end in the direction of the jade-shaped blade and opens the meat 4. The chop cutter according to claim 3, wherein the cutting is performed by conveying the raw wood in the direction of the slanted blade.
Here, as the stopping member, the conveying end on the blade side of the mounting side moved to the outside of the apparatus main body from the conveying position in the direction of the jade-shaped blade, on the blade side and the gripping part side at both ends of the carrying table in the direction of the jade-shaped blade Is a stop member attached to the operator side of the blade cover so as to swing in parallel with the moving direction of the mounting table, and its lower end abuts against the mounting table that moves outward and moves. It is desirable that the stop member has a length that does not come off the mounting table when the mounting table stops. As another means, the extension position of the air cylinder is set longer than the guide member of the mounting table, and the position outside the main body of the mounting table is determined by the length of the guide member, and the piston of the air cylinder is pushed in from that position. And the stop member which stands up with a link mechanism at least on one side of the mounting table by the pressing force may be used.

The invention according to claim 5
A shutter that goes in and out between the meat log pierced by the claw member and the slanted blade-shaped cutter, and the claw member sandwiches the meat log between the shutter and the contact plate so as to pierce the meat log, 2. The shutter is withdrawn from between the meat log pierced by the claw member and the slump-shaped blade before the claw member stabs the meat log and transports it in the direction of the slant-shaped blade. Or it is a chop cutter of Claim 3.
As a result, the gripping part is moved forward until the tip of the meat log abuts against the shutter so that the claw member provided with the actuator in the pressurization part can be frozen and the hard meat log can be reliably pierced. After the meat log is sandwiched between the plates, the nail member is pierced into the meat log so that the meat log does not escape and cannot be pierced.
Further, since the mounting table according to claim 3 is moved to the outside of the main body of the apparatus from the conveying position in the direction of the slanting blade, the mounting table and the takeout port are separated, so that the shutter of claim 5 is attached. There is a lot of space, and it is particularly preferable that the shutter is moved in and out from the lower side of the outlet. In the upward direction, a space for housing a member for driving the shutter is required, which tends to be higher than the conventional apparatus main body and tends to give an impression that the entire apparatus is enlarged, and cleaning work is not easy. On the other hand, since the mounting table according to claim 1 is a groove portion having a U-shaped cross section that is open upward, as seen from the past, an insertion hole having a shutter width is formed on the bottom surface or side surface of the groove portion in the vicinity of the outlet. The shutter will come in and out. In addition to the case where the shutter is moved in parallel with the rotation surface or cutting surface of the slanted blade or parallel to the opening of the takeout port, the shutter is attached to the arm tip that moves 90 degrees, The position where the opening is blocked, the arm moves 90 degrees, the shutter surface is parallel to the conveying direction toward the jade-shaped blade, and the inner side of the mounting table or above the mounting table that does not obstruct the conveyance toward the jade-shaped blade You may reciprocate with the position which waits in the direction. However, after the nail member is pierced into the meat log, when removing the shutter, it is necessary to move the gripping portion at high speed so that the shutter moving 90 degrees does not come into contact with the tip of the meat log so that the meat log is moved backward.
Instead of the shutter, the ball-shaped blade is taken out and stopped so as to close the mouth, and the meatball is sandwiched between the blade-shaped blade and the gripping plate abutment until the tip of the blade is brought into contact with the blade. Then, the nail member can be pierced into the meat log. In addition, when the pressing force of the gripping part is large, the jade-shaped blade may be bent or deformed. Therefore, the thickness of the jade-shaped blade is increased, the joint with the rotating shaft is strengthened, or the blade other than the joint is used. It is also possible to provide a member that presses the peripheral edge at a position where the ball-shaped cutter cuts off the opening and stops and suppresses the curving or deformation of the ball-shaped blade.

The invention according to claim 6
6. The chop cutter according to claim 5, wherein a pressing member is provided on the shutter to prevent the raw meat sandwiched by the contact plate from deviating from the conveying direction toward the blade.
As a pressing member for raw meat wood, a needle that protrudes from the surface of the shutter that comes into contact with the raw meat wood is suitable because the needle body that pierces the raw meat wood pierces the frozen meat raw material widely and shallowly and increases the holding force. is there. As another means, there is a method in which a non-slip uneven portion or a concave or recessed curved surface into which a front end portion of the meat raw wood is fitted is formed on the surface of the shutter that contacts the raw wood. However, the pressing member means that the meat log is positioned along or in parallel with the conveying direction toward the slanted blade, and does not mean that it is pressed or pressed against the bottom surface of the mounting table.
In addition, since the mounting table is installed with the bottom surface inclined relative to a conventional U-shaped cross section with an open top, it is easy to fit into the L-shaped corner by its own weight, and the other end of the meat raw wood is the grip part Since it is held by the holding teeth, when it is pressurized by the gripping part, it is now possible to reliably hold the frozen meat log by holding only the blade end of the meat log with the pressing member. . Further, auxiliary members such as a positioning member for placing the meat log at the center and a width adjusting member for approaching one of the side walls, which are necessary for a conventional mounting table having an U-shaped cross section with an upper opening, are no longer necessary.

The invention according to claim 7 provides:
A sensor for detecting the pressure applied from the gripping part is provided on the meat log sandwiched between the shutter and the contact plate, and when the predetermined pressure amount is reached, pressurization of the gripping part is stopped. The chop cutter according to claim 5.
Here, the sensor for detecting the applied pressure detects the amount of torque generated in the actuator of the gripping part due to the pressurization, and measures the amount of bending or bending of the sensor provided in the actuator and the shutter pressed against the raw wood. Therefore, a sensor provided on the apparatus main body side for measuring the amount of displacement of the front end of the shutter, a sensor provided for the shutter for measuring the deflection angle of the base end side of the shutter or the amount of parallel movement of the shutter, etc. Depending on the performance or material of the actuator or shutter, a selection or a plurality of combinations is used.

Furthermore, the invention according to claim 8 provides
The gripping part starts to retreat in a state where the meat log is pierced when approaching a predetermined distance to the claw-shaped blade, and the nail member is pulled up from the meat log and cut at the meat log drop opening provided at the conveyance part of the grip part. 4. The chop cutter according to claim 1 or 3, wherein the meat log after finishing is discarded.
Thereby, since the disposal process of the raw meat logs that have been cut is automatically performed, the worker only needs to put the raw meat logs into, and the efficiency is improved. Furthermore, if a meat log input device is added, a fully automatic device is expected to be completed.
The meat log drop opening is opened at the end of the mounting table where the gripping part travels, and stops when the retracted gripping part gets over the meat log drop opening and the meat log is placed directly above the meat log drop opening. Then, the meat log that has been cut by lifting the claw member from the meat log can be dropped and discarded. Further, since the mounting table according to claim 3 is moved to the outside of the apparatus main body from the conveying position in the direction of the jade-shaped blade, when the end of the mounting table is not connected to the apparatus main body, a specific meat log drop opening is provided. It is not necessarily formed, but if it has a space for dropping the meat logs behind the mounting table, it can function as a meat log drop opening. Further, the position of the container for collecting the dropped meat logs may be not only the outside of the apparatus main body but also the inside or the lower side.
In addition, the meat log drop opening can be opened not only at the end of the mounting table on which the gripping unit travels, but also at a position where the meat log is exchanged, and a lid member that is closed can be attached. Then, when the gripping part starts to move backward, open the lid member, place the meat log directly above the opened meat log drop opening, drop the meat log after cutting by lifting the claw member from the meat log Discard. After the cover member is closed again, the next meat log is placed on the cover member, and the gripping unit can start the piercing operation. Thereby, since the length of a conveyance path can be made substantially the same as a conventional product, the installation area of an apparatus does not change. As for the opening of the lid member, it is possible to attach a lid member opening / closing device on the machine base side, or attach another actuator for opening operation to the gripping part, for example, extend the piston to the conveyance path side and close it A mechanism for opening the biased lid member against the biasing force may be provided.

The invention according to claim 9 is
9. The gripping portion is provided with an extruding member that pulls away a meat log that does not fall even when the claw member is pulled up from the abutment plate, and the cut raw meat log is discarded to the meat log dropping port. It is a chop cutter as described.
As an extruding member, there is an extruding rod that protrudes and retracts from the abutment surface in the direction of the meat log, and gives an urging force by a coil spring in the protruding direction, and the urging force of the coil spring pierces the weight of the meat log and the claw member Therefore, the force is adjusted so as to be smaller than the force pressed by the gripping portion and larger than the adhesive force of the meat log that does not fall even when the claw member is pulled up and the sticking force of the holding teeth of the contact plate. Further, as another push-out member, the rod body is erected on the side wall of the main body in the direction in which the gripping part is retracted, and an insertion hole is made in the contact plate so that the tip of the rod body does not collide with the gripping part, After removing the claw member of the gripping part from the end piece, the holding part is further retracted, and the end part of the stick that the tip of the rod body abuts the end piece through the contact plate and adheres to the contact surface of the holding part It may be one that drops.

  As described in detail, according to the first aspect of the present invention, since the pressurizing unit is provided with an actuator, even if it is a hard frozen meat log, the operator pushes it hard and the toes come off and the posture is lost. The nail | claw member can be pierced reliably without such a thing. In addition, since the actuator is controlled so that a constant pressure is maintained on the toe of the claw member, even if the frozen meat on the toe melts and loosens, the nail part is further pierced and the predetermined pressure is maintained in the pierced state. Since the actuator is actuated until the end of the operation, the section to be cut is always provided with a predetermined thickness by continuing to pierce the toes that are being thawed.

  Further, according to the present invention of claim 2, after the meat log is simply cut and replaced with the next meat log, if the detector can confirm that the lid cover of the mounting table is closed, the chop cutter While starting and continuing continuous operation, if the shape of the meat log is difficult to hold down with the claw member, open the lid cover and the operator manually presses the meat log before manual operation on the control panel etc. The operator can start the chop cutter by operating the start switch.

  Further, according to the third aspect of the present invention, since only the upper side of the mounting table has been opened in the past, it has been an operation of lifting from the outer frame of the apparatus main body and lowering to the mounting table. Since the mounting table moves to the outside, there is no need to lift a heavy meat log even for the height of the outer frame.

  According to the fourth aspect of the present invention, when the meat log is supplied to the mounting table moved to the outside of the apparatus main body from the conveying position in the direction of the jade-shaped blade, the meat log is released from the open end that becomes the main body side of the mounting table. Since it does not slide down, a wasteful operation of having to slowly place meat logs is eliminated, and the supply work can be performed efficiently.

  According to the fifth aspect of the present invention, the nail member is pierced into the meat log after the meat log is sandwiched between the shutter and the contact plate of the gripping part. The frozen and hard meat log can be stabbed reliably without slipping out by sliding it in the forward direction of the gripping part, and the supply process of the meat log can be performed efficiently.

  According to the sixth aspect of the present invention, when the pressure is applied by the gripping portion, the claw member is frozen and the hard meat log is surely frozen without sliding only the blade end of the meat log to the left and right. It can be pierced, and the supply of raw meat can be done efficiently.

  According to the seventh aspect of the present invention, since the pressure applied through the meat log is directly detected, the pressure according to the bending condition or the bending condition due to the frozen state of the meat log is optimal from the gripping part. The claw member provided with the actuator in the pressurizing part is frozen and can securely pierce the hard meat log, so that the supply work of the meat log can be performed efficiently.

  According to the eighth aspect of the present invention, since the processing of cutting the meat raw wood that has been cut is automatically performed, the worker only performs the work of putting the meat raw wood, and the efficiency is improved. Furthermore, if a meat log input device is added, a fully automatic device is expected to be completed.

  According to the ninth aspect of the present invention, the end of the meat raw wood that has been thawed and increases the adhesive force to release the claw member and does not fall off even if the claw member is released is forcibly applied to the meat log drop opening. Therefore, the efficiency of work can be improved, and the reliability of the entire apparatus when automated can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the present invention is not limited to this.
The entire apparatus of the chop cutter according to the present invention is equivalent to FIG. FIG. 2 is an enlarged explanatory view of the gripping portion, (a) is an explanatory view showing the longitudinal direction of the mounting table 12 on the left and right of the drawing, and (b) is the right side of (a).
The gripping part 13 includes an abutment plate 20 that abuts on the rear end of the meat log M, a claw member 21 that pierces the abutted meat log M from above, and a pivot shaft 22 that rotates the claw member 21. The nail member cover 23 for dropping the raw raw meat M that has been pulled up and pulled up, the left and right side plates 24, 25, the holding teeth 26 that pierce the raw raw wood M from below, the top plate 27, and the back plate Reference numeral 28 denotes a base frame. Wheels 29 that move the mounting table 12 are attached to the outside of the left and right side plates 24, 25, and are connected to a drive unit (not shown) to reciprocate in the direction of the cutter.
A slide hole 31 is extended at the base end of the claw member 21 having a hook-like tip, and an air cylinder 32 serving as an actuator as a pressurizing unit is attached to the back plate 28. The piston 33 of the cylinder 32 is locked. When the piston 33 extends, the claw member 21 rises upward through the slide hole 31 as shown by the two-dot chain line to release the piercing state, and when the piston 33 contracts, the claw member 21 rises downward and enters the piercing state. Operates as follows. The drive unit of the air cylinder 32 is built in the apparatus base side, and a pressure feeding tube is arranged on the connecting member 30 for transporting the gripping part 13 by the mounting table 12.

Next, FIG. 3 is a flowchart which shows the operation | movement procedure for a holding | grip part to replace a raw log. First, it is confirmed whether or not the rotation of the blade is stopped in step S1, and if it is stopped, it is checked whether or not it is returned to a predetermined replacement position of the mounting table 12 and stopped in step S2. If the switch is stopped at the replacement position, it is checked whether the changeover switch is a manual switch, that is, whether the cover can be detected (step S3). If it is, the lid cover is not detected and switched so that it can be operated with a manual switch (step S4). When the manual switch is operated, the actuator is activated and the claw member is pierced and activated. And cancel the piercing state.
If the manual switch cannot be operated in step S3, the lid cover can be opened / closed so that the opening / closing state of the material loading cover can be detected by opening the material loading cover above the mounting table. Since the device (step S5) detects the “open” state, the claw member 21 of the grip portion 13 is raised to release the piercing state (step S6). As a result, the meat log that has been cut is removed, and the next meat log is placed on the mounting table. When the material input cover is closed, the open / close detector detects the “closed” state (step S7), so that the claw member 21 of the gripping portion 13 is lowered to pierce the next meat log (step S8). The replacement work is complete and you can move to the slicing work.

Next, FIG. 4 is explanatory drawing which shows the operating condition of a chop cutter. In addition, although the holding part is displayed in two places, it is for description and is used by one.
The gripping portion 13 located on the left side of the drawing cuts the meat log while approaching the jade-shaped blade inside the cover 11a, and if it approaches closer than a predetermined distance, the jade-shaped blade contacts the claw member and breaks. Therefore, when the predetermined distance is reached, the retreat is started with the meat log M pierced.
The meat log M1 that has been cut by lifting the claw member 21 from the meat log M can be discarded at the meat log drop opening 16 provided on the terminal side of the mounting table 12 to which the retracted gripping portion 13a is conveyed. Although the meat logs to be discarded are collected in a disposal container, the direction of disposal from the meat log drop port 16 is not limited to the longitudinal direction of the mounting table 12, and even if the disposal container is accommodated inside the machine base to improve hygiene good.

Next, another embodiment of the present invention will be described with reference to the accompanying drawings. Note that the present invention is not limited to this.
5 and 6 are explanatory views showing the operating state of the chop cutter, as in FIG. 4. FIG. 5 shows a state in which the meat log M is pierced by the claw member 21, and FIG. 6 shows the meat log M as a section. The state after cutting is shown. FIG. 7 is an enlarged partial explanatory view of the grip portion 13 and the shutter of FIG. About the whole apparatus of the chop cutter 10, the same code | symbol is attached | subjected about the member equivalent to FIG. In FIG. 6, the gripping portion 13 is displayed at two locations for the sake of explanation, and the gripping portion shown on the right side of the drawing shows the state immediately before dropping the end meat of the raw meat by an imaginary line. is there.
The mounting table 12 shows only one of the two plate surfaces having an L-shaped cross section, and the other one located on the front side of the figure can be removed with a knob screw for cleaning, so that FIG. 5 is omitted. doing. The position of the mounting table 12 in FIG. 6 indicates the conveyance position in the direction of the jade-shaped blade, and the meat log M pierced by the left claw member 21 among the two gripping portions 13 is the direction of the jade-shaped blade. It shows a state in which cutting is completed to a predetermined dimension. The mounting table 12 at the conveying position in the direction of the slanting blade can be moved linearly toward the standing position of the operator on the front side of the sheet by the air cylinder 41 attached to the lower side. By moving the mounting table 12 to the outside of the main body, it is possible to easily supply a heavy meat log closer to the worker.
In addition, a guide member is provided to move outside the mounting table 12. The L-shaped member 42 fixed to the lower side of the mounting table 12 is fixed to a rail 43, and the rail 43 is sandwiched between rollers 44, 44 so as to be slidable in the forward direction of the figure, which is the longitudinal direction of the rail 44. The rollers 44 and 44 are supported, and are attached to the apparatus main body by an installation portion 45. Thereby, the mounting table 12 is guided in the longitudinal direction of the rail 44 and can move linearly to the outside of the apparatus main body.
A shutter 51 is attached to the lower side of the outlet 14 so as to be able to enter and exit. A plurality of needle bodies 52 project from the surface of the shutter 51 facing the meat log M or the gripping portion 13. And since the shutter 51 is attached to the rotating shaft 53 attached to the apparatus main body and is connected by the knob screw 54 in the middle, the knob screw 54 is loosened and only the shutter 51 is removed, and cleaning can be performed.
The grip 13 is the same as the structure shown in FIG. 2, and the claw member 21 pierced into the meat log slides through the slide hole 31 when the piston 33 is extended, and the lower end is pushed forward from the rotation shaft 22. The upper end of the integrated rotation shaft 22 is rotated rearwardly and detached from the meat log M. If the meat log M adheres to the contact plate 20 when it is detached, the push bar 34 attached to the contact plate 20 pushes the meat log M so that the contact plate 20 is removed from the insertion hole of the contact plate 20. It has become. The pushing bar 34 pushes out the meat log M attached to the contact plate 20 by the urging force of the coil spring 35 inserted inside.
10a is a cover on the back side of the apparatus main body, and stores a driving member for reciprocating the gripping portion 13 in the conveying direction in the direction of the slanting blade-shaped cutter, a rotational driving member for the slanting-shaped blade 11 and the like.

FIG. 8 is an explanatory view taken along line AA in FIG. 6, (a) is an explanatory view showing a state in which the mounting table 12 is in a conveying position in the direction of the slanting blade shape, and (b) is a mounting table 12. It is explanatory drawing of the state which moved to the apparatus main body outer side from the conveyance position to a jade-shaped blade direction.
The mounting table 12 is composed of two plate surfaces having an L-shaped cross section, and one of the mounting tables 12b on the worker side can be removed with a knob screw 12c, so that it can be disassembled and cleaned. The position of the mounting table 12 in FIG. 8A indicates the transport position in the direction of the jade-shaped blade, and the meat log M transported to the back side in the figure by the grip portion 13 is pushed out from the take-out port 14 by a predetermined dimension. Cut with a jade-shaped blade.
The air cylinder 41 for moving the mounting table 12 at the transfer position in the direction of the jade-shaped blade to the outside of the apparatus main body is attached at the base end to the inclined bottom surface of the apparatus main body, and the piston 41a at the tip is located on the bottom surface of the mounting table 12. It is attached. It is possible to move linearly toward the worker's standing position, and by moving the mounting table 12 to the outside of the apparatus main body, it is possible to easily supply heavy meat raw wood close to the worker. In addition, since the moving direction is an obliquely downward direction that is lower than the horizontal, the height of the mounting table 12 that has been moved to the outside is further lowered, and it becomes easier to place the meat log M.
In addition, since the inside of the apparatus main body is an inclined bottom surface, when the meat log M at the conveying position in the direction of the slanting blade is removed from the gripping portion 13 and dropped, it slides toward the worker side along the inclined bottom surface to the meat receiving box 17. Collected.
Reference numeral 60 denotes a stop member whose upper end is attached to the operator side of the blade cover 14a so as to swing in parallel with the moving direction of the mounting table 12, and its lower end abuts on the mounting table 12 moving outward and moves. It is a stop member having a length that does not come off the mounting table 12 when the mounting table 12 stops. The mounting table 12 is open at both ends in the conveying direction toward the jade-shaped blade, and when the meat log is supplied from one open end, the frozen meat log M slides on the mounting table 12 and falls from the other open end. The stop member 60 prevents the meat log M from falling. Further, when the mounting table 12 is retracted to the conveying position in the direction of the jade-shaped blade by the contraction of the air cylinder 41, the stop member 60 opens both ends in the conveying direction in the direction of the jade-shaped blade and holds the gripping portion from one end. The stop member 60 in (a) stands by at a position that does not reach the take-out port 14 so that 13 contacts the meat log M and cuts the meat log from the other end with a slanted blade.

9 is an explanatory view taken along line B-B in FIG. 6, (a) is an explanatory view showing a state in which the shutter 51 opens the take-out port 14, and (b) is a view in which the shutter 51 is taken out by the take-out port 14. It is explanatory drawing of the state which has closed.
The shutter 51 attached to the lower side of the outlet 14 so as to be able to enter and exit is provided with a plurality of needle bodies 52 projecting from the surface of the shutter 51 facing the meat log M or the grip portion 13. The shutter 51 is rotatable by a rotation shaft 53 attached to the side surface of the apparatus main body where the take-out port 14 is formed. When the extended air cylinder 55 contracts, the shutter 51 is turned to close the take-out port 14. . The closing position considers the L-shaped cross section of the mounting table 12 and closes a part of the extraction port 14 around the V-shaped corner. In addition, since the shutter 51 is connected to the drive portion of the air cylinder 55 by a knob screw 54, the knob screw 54 is loosened and only the shutter 51 is removed for cleaning.
Further, a position detection sensor 56 such as an infrared ray is attached to the side of the take-out port 14, and when the meat log is pressed against the shutter 51 in order to pierce the claw member 21, the deflection amount of the shutter 51 is transmitted to a control unit (not shown). Then, feedback is performed from the calculated pressing pressure to the pressing pressure control of the grip portion 13.

FIG. 10 is a flowchart of the chop cutter according to the embodiment from FIG. Each detection sensor moves to the next process while confirming the completion of the process at each step.
When the input switch on the operator side of the operation panel 15 or the apparatus main body is turned on (step 1, hereinafter S1), the air cylinder 41 is operated and the mounting table 12 is slid by the guide member such as the rail 43 to the blade side. It moves to the outside of the apparatus main body while descending from the transfer position (S2, FIG. 8b shown). The worker places the new meat log M on the mounting table 12 moved to the outside of the apparatus main body while using the stop member 60 so as not to fall (S3). When the operator presses the closing switch (S4), the air cylinder 55 contracts and the shutter 51 rises to close the takeout port 14 (S5, FIG. 9b shown), and then the air cylinder 41 contracts and is mounted. The mounting table 12 returns to the conveying position toward the blade (S6, FIG. 8a is shown).
The gripping portion 13 that has been waiting away from the blade 11 moves forward, and continues to move forward even if the meat plate M contacts the abutment plate 20 or the tip of the meat log M contacts the shutter 51 (S7). Until the deflection amount of 51 reaches a predetermined amount (S8), the pressing force of the gripping portion 51 does not reach the predetermined force, so the forward movement is continued.
When the amount of deflection of the shutter 51 reaches a predetermined amount, the forward movement of the gripping portion 13 is stopped, and a claw member 21 is protruded from the meat log M sandwiched between the shutter 51 and the contact plate 20 (shown in FIG. 5). The grip part 13 is moved backward by a predetermined amount with the shutter 51 and the meat log M released from contact with each other (S9). Here, it is detected by the sensor whether the claw member 21 is surely projecting on the meat log M, whether the meat log M is also retracted as the grip portion 13 is retracted (S10), and if the piercing state is insufficient. After releasing the claw member 21 (S11), the process is repeated from the advance of the gripping part 13 in step 7 again.
If the pierced state of the claw member 21 is sufficient, the shutter 51 is lowered and the takeout port 14 is opened (shown in FIG. 9a) to start the rotation of the jade-shaped blade (S12). Is moved forward at high speed to bring the meat log M close to the position just before the take-out port 14, and the section 13 is cut by advancing the gripping portion 13 in synchronism with the rotation of the blade 11 by the thickness of the section.
When cutting progresses and the meat log becomes shorter, the gripping part 13 reaches a predetermined starting position in the conveyance path. Therefore, in order to end the cutting of the meat log, the rotation of the cutter is stopped and the gripping part 13 is retracted (S15). (See FIG. 6.) When the gripping portion 13 reaches the end position provided with a drop opening for dropping the end meat of the raw meat (S16), the gripping portion 13 stops moving backward and the claw member 21 is opened. The end meat of the raw meat log is dropped and discarded from the drop opening 16 to the meat receiving box 17 and the process ends (S) 18). If the end plate adheres to the abutment plate 20 and does not fall, the extruding bar 34 will push out the end portion from the surface adhering to the abutment plate 20 when the pressing force by the claw member 21 is lost. Can be made.
In the system in which the raw meat is supplied by an automatic conveyor, steps 3 to 4 in the flowchart are changed as follows.
When the input switch on the operator side of the operation panel 15 or the apparatus main body is turned on (step 1, hereinafter S1), the air cylinder 41 is operated and the mounting table 12 is slid by the guide member such as the rail 43 to the blade side. While descending from the transfer position, the apparatus is moved to the outside of the apparatus main body (S2). One meat log is transferred from the automatic conveyor whose supply position has been set in advance to the mounting table 12 moved to the outside of the apparatus main body, and the tip of the new meat log M is dropped using the stop member 60. There is nothing to do (S3). If the meat logs are correctly placed on the mounting table and the various sensors confirm that the mounting table does not come into contact with other members even when the mounting table returns to the original position, a command to return the mounting table is output (S4), After the air cylinder 55 contracts and the shutter 51 rises to close the take-out port 14 (S5), the air cylinder 41 contracts and the mounting table 12 returns to the conveying position toward the cutter (S6).
