Description

The present invention relates to a meat slicer using a round blade . More specifically, the present invention relates to an improvement in a meat slicer that slices block- like meat (block meat) such as beef and pork.

  As a typical conventional meat slicer, for example, as shown in Patent Document 1 (Japanese Utility Model Publication No. 3-36794), a round blade provided at a fixed position of a machine base and rotating in a vertical plane, and a bottom portion And a meat box that is provided with a receiving blade at the tip and a side wall guide plate on both sides and has a square bowl shape. The front end of the meat box is a round blade. The block meat fed from the front end of the meat box by reciprocating horizontally on the machine base along the blade surface is directed toward the corner formed by one side wall guide plate and the receiving blade body. There is one that is sliced with a round blade while pressing.

  As another conventional meat slicer, using a rotary blade made of a spiral or curved plate blade as disclosed in Patent Document 2 (Japanese Patent No. 3345550), the same as that in Patent Document 1 is used. It is also known that a rotating blade is passed through the front end portion of the meat box having the structure, and the block meat is sliced while being pressed toward a corner portion formed by one side wall guide plate and the receiving blade body.

In addition, in the meat slicer, an upper conveyor such as an upper feed roller is provided above the tip of the meat box so as to press the upper part of the block meat, and cooperates with the conveyor provided at the bottom of the meat box. Block meat is sent out.
Japanese Utility Model Publication No. 3-36794 Japanese Patent No. 3345550

In the conventional block meat slicer as described above, especially when slicing soft raw meat or the like, the block meat is pressed against the side wall guide plate by a rotary blade such as a round blade or a plate blade, and adheres to the bottom conveyor. In addition, the resistance to the delivery of the block meat by the upper conveyor is increased, which obstructs the delivery of the block meat by the bottom conveyor and the upper conveyor. In particular, in a slicer having a form in which the meat box is reciprocated left and right as disclosed in Patent Document 1, the block meat is guided by the side wall guide plate due to the inertial force of the block meat caused by the movement of the meat box. since Ru is pressed against the, the tendency is strong. Therefore, the transfer of the block meat located on the side wall guide plate side of the block meat is likely to be delayed, and the side wall guide plate side is thinly sliced by a rotary blade such as a round blade or a plate blade. As a result, the thickness is uniform. A sliced meat piece cannot be obtained.

  Further, in the conventional slicer, the corner formed by the side wall guide plate and the bottom surface of the meat box is substantially perpendicular when viewed in a cross section in the cut surface (that is, in a cross section orthogonal to the feeding direction). It has become. The front end of the corner that has become substantially right-angled is the end of the cut when the block meat is sliced, and the block meat is pressed against this corner by a rotary blade such as a round blade or plate blade. The sliced meat pieces are cut by being sliced with a rotary blade such as a blade.

  When slicing block meat (such as pork loin) with a relatively large round shape in such a conventional slicer, the outline of the block meat should be exactly along the inner surface of the corner formed at a right angle. Therefore, a triangular gap is formed between the block meat and the inner surface of the corner, and the block meat in the vicinity of the gap is sliced in a floating state without being supported by the receiving blade surface. Thus, if the block meat is sliced in a free state with no receiving blade surface to be received, the sliced meat piece cannot be reliably separated from the block meat, and the sliced meat piece is drawn into the rotary blade. Loss may occur, the shape of the sliced meat pieces obtained may be disturbed, and subsequent operations such as removal of the sliced meat pieces may be hindered.

The present invention has a problem associated with the conventional meat slicer as described above, that is, the block meat is pressed against the side wall guide plate by the round blade and adheres, so that the side wall guide plate side is sliced thinly and a sliced meat piece having a uniform thickness is obtained. And / or a triangular gap between the block meat and the inside of the corner, which prevents the sliced meat piece from being reliably separated from the block meat, and the sliced meat piece is pulled in by the round blade An object of the present invention is to provide a meat slicer that can solve problems such as loss, disorder of the shape of sliced meat pieces obtained, and problems in subsequent work such as taking out sliced meat pieces.

In the present invention, a meat slicer comprising a round blade rotating around a horizontal axis at a fixed position of a machine base and a meat box reciprocating, the bottom conveyor on which the meat is placed on the block, the bottom A side wall guide plate provided on one side of the conveyor and an upper feed roller for pressing the upper part of the block meat are provided, and the meat box approaches the round blade so that its front end is along the blade surface of the round blade. In a meat slicer that reciprocates in the direction of separation ,
The bottom conveyor is configured to feed the placed block meat toward the front end in conjunction with the movement of the meat box, and the upper feed roller is configured to send the block meat in cooperation with the bottom conveyor. And
The side wall guide plate is provided perpendicular to the blade surface of the round blade on the side on which the block meat is pressed when the round blade slices the block meat fed from the front end of the meat box. The above-mentioned object is achieved by a meat slicer characterized in that at least a part of the guide plate is constituted by a conveying surface of a side conveyor that moves in synchronization with the bottom conveyor .

As described above, since at least a part of the side wall guide plate is configured by the conveyance surface of the side conveyor that moves in synchronization with the bottom conveyor, even if the block meat is pressed against the side wall guide plate by the round blade, it is pressed. The block meat is moved in synchronism with the bottom conveyor by the conveying surface of the side conveyor and sliced with a round blade in that state, so that a sliced meat piece having a uniform thickness can be obtained.

  In this case, the abutting side ends of the endless belt-shaped conveyor belts constituting the side conveyor and the bottom conveyor are integrally connected with an elastic band, and the elastic band also moves in synchronization with the bottom conveyor. Thus, it is preferable to appropriately round the inside of the connecting portion of the stretchable band.

  Further, by arranging the side conveyor at an angle formed by the upper surface of the bottom conveyor and the side wall guide plate so as to be inclined toward the side wall guide plate side, the thickness of the sliced meat pieces is made uniform. In addition to slicing, by placing the side conveyor at an angle toward the side wall guide plate, the triangular gap between the block meat and the inside of the corner is eliminated or reduced. Even if it is a block meat such as pork loin or soft raw meat with a relatively large roundness, the sliced meat piece can be reliably separated from the block meat, and the meat piece is not drawn into the rotary blade and no loss occurs or As a result, the shape of the sliced meat piece obtained is not disturbed, and subsequent operations such as taking out the sliced meat piece can be performed smoothly.

  In this case, the side conveyor and the bottom conveyor are inclined at an angle of more than 90 ° and less than 180 °, particularly preferably about 135 °. It is preferable that the triangular gap between the inner surfaces of the parts can be almost eliminated.

As described above, a corner conveyor formed by the top surface of the bottom conveyor and the side guide plate is provided with a stretchable belt having an appropriate rounded inner side or a side conveyor inclined to the side wall guide plate, and synchronized with the bottom conveyor. As a result, the block meat pressed against the corner by the round blade is reliably fed, and a sliced meat piece having a uniform thickness can be obtained.

An upper feed roller for feeding the block meat in cooperation with the bottom conveyor while the meat slicer is supported by a swing arm at a position above the front end of the meat box and is swung up and down to press the top of the block meat If you are provided a plurality of the upper feed roller is located in a corner portion of the meat box out of the upper feed roller, said other so as not to interfere with the downward movement of the other of the upper feed roller in the linear section preferably Rukoto separately swingably provided with the upper feed roller. By doing in this way, the block meat located in a bottom conveyor part and a corner part can be pressed almost uniformly, and delivery of a block meat can be performed smoothly.

  In the present invention, the receiving blade having a receiving surface for receiving the end of the block meat from each conveyor from the sending tip of the bottom conveyor to the sending tip of the side conveyor and close to the cutting edge of the rotary blade The end of the block meat is reliably received by the receiving surface including the corners of the receiving blade body, and the rotating blade and the receiving blade body allow the article on the cutting board to be knife-cut. Furthermore, it is preferable that the block meat is sandwiched between the blade edge of the rotary blade and the receiving blade of the receiving blade body so that the slice can be reliably sliced.

  In particular, when the present invention is applied to a meat slicer in which the meat box reciprocates horizontally in the plane of rotation of the round blade, the meat box is formed on the blade body close to the edge of the round blade at the corner. The received blade is inclined toward the side wall when viewed from the front in the feeding direction of the bottom conveyor, and the position of the end point on the side wall side of the inclined portion is higher than the rotation center line of the round blade. Therefore, the block flesh pressing force of the round blade can be received by the receiving blade formed on the receiving blade body until the end of cutting by the round blade, which is preferable.

In addition, the said receiving blade formed at the tip of the receiving blades body said are the cutting edge of the round blade is urged toward each other, regulating the biasing direction of movement of the receiving blade or the circular blade It is preferable that the stopper meat is provided and the restriction position by the stopper is adjustable, so that the block meat can be sliced reliably by the round blade and the receiving blade body.

The round blade wears as the block meat slices. Corresponding to wear of the round blade, the receiving blade body or the round blade is moved to adjust the interval between the receiving blade body and the round blade. The receiving blade or round blade moves in the backward direction by a distance greater than the dimensional difference in the blade thickness direction between the blade edge before use of the round blade and the blade edge of the round blade when it reaches the endurance limit. This is preferable because the round blade can be easily replaced.

Further, Rutotomoni attaching the receiving blade body meat box via a leaf spring, may be provided with a guide means for restricting the movement of the feed to the other directions receiving blade.

Further, the receiving blade body is supported by the meat box so that the receiving blade formed at the tip of the receiving blade body is close to the cutting edge of the round blade , and senses that the operation process is not slicing during operation. In addition to providing the sensing means, in the process of not slicing, it is possible to provide a retracting means for the receiving blade body for separating the receiving blade from the cutting edge of the round blade .

  Further, when the present invention is applied to a meat slicer in which the meat box is reciprocally movable in the horizontal direction and the block meat is sliced only during the forward stroke of the meat box, the sensing means performs the backward stroke of the meat box. Preferably, the retracting means of the receiving blade body is a moving device that retracts the receiving blade body so as to separate the receiving blade from the blade edge based on the detection result of the sensor.

  According to the present invention, the problems associated with the conventional meat slicer disclosed in Patent Document 1 as described above can be solved.

  More specifically, according to the present invention, the meat that can solve the problem that the side wall guide plate side is thinly sliced and a sliced meat piece with a uniform thickness cannot be obtained because the block meat is pressed against and adhered to the side wall guide plate by the round blade. A slicer is provided.

Furthermore, since a triangular gap is created between the block meat and the corner inner surface at the same time or separately from the effect, the sliced meat pieces cannot be reliably separated from the block, and the meat pieces are round blades. Thus, a meat slicer is provided that can solve problems such as loss due to being pulled in, disturbance of the shape of the sliced meat piece obtained, and hindrance to subsequent operations such as removal of the sliced meat piece.

  Hereinafter, a meat slicer according to the present invention will be described in detail with reference to the accompanying drawings illustrating embodiments of the present invention. FIG. 1 is a perspective view showing the whole meat slicer according to the first embodiment of the present invention.

  Since the basic structure of the meat slicer according to the first embodiment is known per se, the detailed description of the known part is omitted, and only the main part related to the present invention will be described.

  In FIG. 1, a round blade 2 rotates in the direction of arrow A in FIG.

  A meat box 3 is provided on the upper surface of the machine base 1. The meat box 3 is provided with a bottom conveyor 4 for feeding out a block meat M (not shown in FIG. 1; see FIG. 2) at the bottom, and a receiving blade body commonly called a “cutting board” at the tip of the round blade 2 side. 42 is provided. Furthermore, in the conventional meat slicer, side wall guide plates (locations 5 and 6 'in FIG. 1) perpendicular to the blade surface of the round blade 2 are provided on both sides of the meat box 3, respectively. The box 3 has a square bowl shape. Note that the side wall guide plate on the side of the round blade 2 indicated by the reference numeral 6 'can be adjusted in position as shown by the two-dot chain line in FIGS.

  With a known reciprocating means (not shown), the meat box 3 is placed on the machine base 1 so that the front end portion (the receiving blade body 42 side) of the meat box 3 is along the blade surface of the round blade 2. It reciprocates in the direction (arrows B and C in FIG. 1) that approaches and separates from the round blade 2 in the direction. The bottom conveyor 4 sends out the block meat M placed in conjunction with the movement of the meat box 3 in the direction away from the round blade 2 (movement in the direction of arrow C) toward the front end.

  In the conventional meat slicer, the block meat M is further sliced while pressing the block meat M fed from the front end of the meat box 3 by the bottom conveyor 4 against the side wall guide plate on the anti-round blade 2 side. The leading edge portion is sliced by the round blade 2 while being pressed toward the corner formed by the side wall guide plate on the side of the anti-round blade 2 and the receiving blade body 42.

  Further, generally, on the upper side of the bottom conveyor 4 that is provided at the bottom of the meat box 3 and feeds out the block meat M, as described later with reference to FIGS. Is provided with an upper feed roller 39 that feeds the block meat M in cooperation with the bottom conveyor 4 while being supported by the swing arm 38 and moved up and down to press the upper portion of the block meat M.

  In the conventional meat slicer, especially when slicing soft raw meat or the like, the block meat M is moved to the side wall guide plate 6 (at a position corresponding to reference numeral 5 in FIG. 1) by a rotary blade such as a round blade 2 or a plate blade. Is attached to the bottom conveyor 4 and the upper feed roller 39, the resistance to the delivery of the block meat M by the bottom conveyor 4 and the upper feed roller 39 is increased, which obstructs the delivery of the block meat M by the bottom conveyor 2 and the upper feed roller 39. . In particular, when the upper feed roller 39 presses the block meat M, a relatively large and soft raw meat or the like protrudes to the side wall guide plate 6 side and is strongly pressed against the side wall guide plate 6 as much. Therefore, transfer of the block meat M located on the side wall guide plate 6 side of the block meat M is delayed, and the meat on the side wall guide plate 6 side is sliced thinly by the rotary blades such as the round blade 2 and the plate blade. As a result, a sliced meat piece having a uniform thickness cannot be obtained.

  The present invention has a problem associated with the conventional meat slicer as described above, that is, the block meat M is pressed against and adhered to the side wall guide plate 6 by the round blade 2, so that the side wall guide plate 6 side is thinly sliced and the thickness is uniform. It aims at providing the meat slicer which can solve the problem that a sliced meat piece cannot be obtained.

  In the embodiment shown in FIG. 1, the side guide plate on the side of the anti-circular blade 2 is constituted by the conveying surface of the side conveyor 5 that moves in synchronization with the bottom conveyor 4. That is, the vicinity of the edge of the bottom conveyor 4 composed of an endless belt-shaped conveyor belt on the side of the anti-round blade 2 in the width direction is erected over the entire area in the traveling direction to form the side conveyor 5. In this embodiment, as shown in FIGS. 2 and 3, the side conveyor 5 is installed substantially orthogonal to the bottom conveyor 4.

  FIG. 2 is a cross-sectional view of an embodiment showing a connected state of the bottom conveyor 4 and the side conveyor 5 on the driven side in the embodiment shown in FIG. In FIG. 2, the abutting side ends of the endless belt-shaped conveyor belts constituting the side conveyor 5 and the bottom conveyor 4 are integrally connected with an expansion band 7, and the expansion band 7 is also connected to the bottom conveyor 4. It can move in synchronism, and a rounded portion (an arcuate cross section having a radius R in the embodiment shown in FIG. 2) is appropriately provided at a position located on the inner side of the connecting portion of the elastic band 7. The size of this radius R is usually set within the range of 10 mm to 100 mm, corresponding to the outer diameter R of the block meat M to be sliced. The elastic band 7 may be made of a soft elastic body or bellows as compared with the bottom conveyor 4 and the side conveyor 5 and may be joined to both the conveyors 4 and 5 to form an integral structure.

  A power transmission method on the drive side of the bottom conveyor 4 and the side conveyor 5 is shown in FIG. In FIG. 3, when the meat box 3 moves in a direction away from the round blade 2 (arrow C in FIG. 1), the moving power of the bottom conveyor 4 is transmitted to the drive shaft 11 of the bottom conveyor 4. A pair of bevel gears 35, 35 meshing with the end of the drive shaft 11 of the bottom conveyor 4 and the end of the drive shaft 12 of the side conveyor 5 are attached, and the side conveyor 5 is synchronized with the bottom conveyor 4. To move.

  In addition, the code | symbol 31 is a frame which comprises the meat box 3, Comprising: The conveyor frame 10 which attached the bottom part conveyor 4 and the side part conveyor 5 is hold | maintained. That is, the frame 31 is a part of the skeleton of the meat box 3 and is located at the bottom of the meat box 3 (below the bottom conveyor 4). In FIGS. 2 and 3, the left and right connecting angles 31c and 31d are connected. Are connected. The connecting angles 31c and 31d are extended in the front-rear direction of the meat box 3, and support the side wall guide plates 6 and the support stays 31b provided at the left and right positions.

  The structure of the conveyor frame 10 on the side of the round blade 2 (left side in FIGS. 2 and 3) is as follows. On the drive side of the bottom conveyor 4 and the side conveyor 5, as shown in FIG. 3, the drive shaft 11 supported on the front end side of the meat box 3 passes through the connecting angle 31c. Further, on the driven side of the bottom conveyor 4 and the side conveyor 5, as shown in FIG. 2, guide pins 10 a protrude from the frame body 31.

  On the other hand, the structure of the conveyor frame 10 on the side conveyor 5 side (right side in FIGS. 2 and 3) is as follows. The connection stay 32 is fastened to the upper end of the support stay 31b attached to the connection angle 31d, and the side conveyor 5 side end of the conveyor frame 10 is supported by the frame 31.

Thus, since at least a part of the side wall guide plate is configured by the conveying surface of the side conveyor 5 that moves in synchronization with the bottom conveyor 4, the block meat M is pressed toward the side wall guide plate 6 by the round blade 2. However, the pressed block meat M is moved in synchronism with the bottom conveyor 4 by the conveying surface of the side conveyor 5 and is sliced by the round blade in that state, so that a sliced meat piece having a uniform thickness is obtained.

Further, the abutting side ends of the side conveyor 5 and the bottom conveyor 4 are integrally connected by the elastic band 7, and a roundness R is appropriately provided inside the connecting part of the elastic band 7, so that the round part is Corresponding to the corner formed by the upper surface of the bottom conveyor 4 and the side wall guide plate 6, the triangular gap between the block meat M and the inner surface of the corner is eliminated or reduced, and the outer shape is relatively large. Even when slicing block meat such as pork loin with roundness or soft raw meat, the block meat M can be sandwiched between the round blade and the receiving blade 42 and sliced. This ensures that the sliced meat pieces can be separated from the block meat, the sliced meat pieces are not pulled into the round blade , loss is reduced or reduced, the resulting sliced meat pieces are not disturbed, and the slices are sliced. Post-work such as removing meat pieces can be performed smoothly.

  In the above embodiment shown in FIGS. 1 to 3, the side conveyor 5 employs a side conveyor 5 having a width over the entire installation distance instead of the side wall guide plate 6, and is substantially orthogonal to the bottom conveyor 4. It was installed.

  On the other hand, in the embodiment shown in FIG. 5, a part (lower part) of the side wall guide plate 6 is a side conveyor 5 that moves in synchronization with the bottom conveyor 4. It is relatively short. Further, as in the embodiment shown in FIG. 2, the abutting side ends of the endless belt-like conveyor belts 4 and 5 constituting the side conveyor 5 and the bottom conveyor 4 are integrally connected by an elastic band 7. In addition, a portion of the connecting portion of the stretchable band 7 that is positioned inside is appropriately rounded, and thus the side conveyor 5 is positioned at the aforementioned corner.

In the embodiment shown in FIG. 6, the side conveyor 5 is inclined with respect to the upper surface of the bottom conveyor 4 toward the side wall guide plate 6 at an angle α, and the side conveyor 5 is arranged at a corner angle. The part is located. The side conveyor 5 and the bottom conveyor 6 are inclined at an angle of more than 90 ° and less than 180 °, particularly preferably an angle α of about 135 °, with the block meat M. The triangular gap between the inner surfaces of the corner portions can be almost eliminated, which is preferable.

  FIG. 4 is a plan view of a conveyor frame to which the bottom conveyor 4 and the side conveyor 5 of the embodiment shown in FIG. 6 are attached, and shows the inclined side conveyor 5 in a developed state in a horizontal plane. The conveyor frame 10 includes a bottom conveyor 4 portion, a side conveyor 5 portion, and connecting rods 13 and 13 that connect the two conveyor portions. The bottom conveyor 4 portion and the side conveyor 5 portion have the same structure except that the width dimension (the horizontal dimension in FIG. 4) is different. That is, the metal 15 and 15 which support the drive shafts 11 and 12 is attached to the front end side in the feed direction of the cross-shaped frame bodies 4a and 5a, and the conveyor belts 4 'and 5' are attached to the drive shafts 11 and 12, respectively. The rollers 9 and 9 to be driven are fixed. The shaft ends of the drive shafts 11 and 12 are connected to each other by a constant velocity universal joint 36 so that the side conveyor 5 moves in synchronization with the bottom conveyor 4.

  Reference numeral 37 in FIG. 6 is a guide plate made of stainless steel or the like, and extends in the longitudinal direction of the meat box 3 at a position inside the constant velocity universal joint 36 to guide the block meat M to make the meat equal. The fast universal joint 36 is prevented from clogging.

  On the rear end side in the feed direction of the conveyor frame 10, idle rollers 20, 20 are supported so as to be movable in the front-rear direction, and the conveyor belts 4 ', 5' are hung on the drive rollers 9, 9 and the idle rollers 20, 20 described above. It has been turned.

  The structure of the conveyor frame 10 described above is substantially the same in other embodiments, and the same reference numerals are assigned to the same or similar parts.

This eliminates or reduces the triangular gap between the block meat M and the inner surface of the corner, and slices block meat such as pork loin or soft raw meat having a relatively large rounded outer shape. However, since the block meat is sandwiched between the round blade and the receiving blade body 42 and sliced, the sliced meat piece can be reliably separated from the block, and the meat piece is not drawn by the round blade and no loss occurs or As a result, the shape of the sliced meat piece obtained is not disturbed, and subsequent operations such as taking out the sliced meat piece can be performed smoothly.

  Further, as described above, the bottom conveyor 4 provided at the bottom of the meat box 3 for feeding the block meat M is rotatably supported by the swing arm 38 at a position above the front end of the meat box 3 and swings up and down. An upper feed roller 39 for feeding the block meat M in cooperation with the bottom conveyor 4 while being moved and pressing the upper part of the block meat M is provided.

  In this case, when one upper feed roller 39 over almost the entire width of the meat box 3 is used, the side conveyor 5 is inclined with respect to the bottom conveyor 4 as shown in FIG. The upper feed roller 39 cannot uniformly press the block meat M placed on the bottom conveyor 4 and the side conveyor 5. Therefore, an embodiment of the present invention that can solve this problem is provided. FIG. 7 shows a side view of this embodiment, and FIG. 8 shows a front view.

As shown in FIGS. 7 and 8, an auxiliary swing arm 40 is supported on an intermediate portion of the swing arm 38 separately from the swing arm 38, and an upper feed roller corresponding to the bottom conveyor 4 among the upper feed rollers 39. 39 is supported on the lower end portion of the swing arm 38, and the upper feed roller 39a located at the corner of the meat box 3 among the upper feed rollers 39 is supported on the lower end portion of the auxiliary swing arm 40, and the upper feed roller 39a is supported. Does not hinder the downward movement of the upper feed roller 39 attached to the swing arm 38. The spring 41 urges the auxiliary swing arm 40 so that the upper feed roller 39a presses the block meat M with an appropriate pressing force. The upper feed roller 39a may be driven by appropriate means.

Next, a receiving blade body 42 called a “cutting board” attached to the tip of the meat box 3 in the embodiment shown in FIG. 6 will be described with reference to FIG. The frame plate 31a constitutes the meat box 3, is located at the tip of the meat box 3, and a receiving blade 42 is attached to the frame plate 31a. As shown in FIG. 9 (a), from the leading end of the bottom conveyor 4 to the leading end of the side conveyor 5, a U-shape is formed, and the block meat M is formed from the bottom conveyor 4 and the side conveyor 5. A receiving blade body 42 having a receiving surface 42a for receiving the end of the rotating blade and having a receiving blade 42b close to the cutting edge of the rotary blade is provided (see FIG. 11).

As described above, the receiving blade body 42 is provided over the leading end portions of the bottom conveyor 4 and the side conveyor 5, and in particular, the upper surface of the abutting portion (the bent portion of the U-shape) of both the conveyors 4 and 5 is It has a gentle curve. Similarly, although not shown in the embodiments shown in FIGS. 2 and 5, a receiving blade body 42 is provided over the delivery tip of the bottom conveyor 4 and the side conveyor 5, The butted portion 5 (corresponding to the corner portion) has a shape along the roundness provided on the inner surface side of the stretchable band 7.

  Here, a leaf spring 43 having an L-shaped cross section, which is screwed to the frame plate 31a in a direction in which the receiving blade 42b formed at the tip of the receiving blade body 42 and the cutting edge of the rotary blade are close to each other, or a spring (see FIG. And a stopper 46 (see FIGS. 13 and 14) for restricting the movement of the receiving blade body 42 or the rotating blade in the urging direction is provided. In FIG. The screwing amount of the bolt 46 configured and contacting the receiving blade body 42 is adjusted, and in FIG. 14, the position of the bearing box 50 that supports the round blade 2 is adjusted by adjusting the screwing amount of the stopper 46. The position is adjustable.

  As shown in FIG. 11 or FIG. 12, the receiving blade body 42 may be attached to the frame plate 31a via the leaf spring 43, and a guide means 45 for restricting the movement of the receiving blade body 42 in directions other than the feeding direction may be provided. .

Further, in the embodiment shown in FIG. 6 or FIG. 8 described above, as shown in FIG. 10, the side conveyor 5 is inclined toward the side wall as viewed from the front in the feeding direction of the bottom conveyor 4. The receiving blade 42 also extends in a U-shape from the bottom conveyor 4 to the side conveyor 5. Since the position of the side wall side end point G of the inclined portion of the receiving blade body 42 is higher than the rotation center line OL of the round blade 2, the block meat M of the round blade 2 is pressed to the end of cutting by the round blade 2. The force can be received by the receiving blade 42 b formed on the receiving blade body 42. Further, since the receiving blade 42b moves with an acute angle β (see FIG. 10) with respect to the round blade 2, even if the cutting edge of the round blade 2 contacts the receiving blade 42b , a so-called biting phenomenon does not occur.

  Further, the round blade 2 is worn with use. Accordingly, as shown in FIG. 15, the receiving blade body 42 or the round blade 2 has a cutting edge (diameter D1) before use of the round blade 2 and a cutting edge when the cutting edge of the round blade 2 is worn and reaches the endurance limit ( When the round blade 2 is replaced with a new round blade, the blade tip and the receiving blade 42b can be moved in the backward direction by the apparatus of FIG. 14 by a distance equal to or larger than the dimension difference c in the thickness direction with respect to the diameter D2). Even if the distance between the receiving blade 42b and the original round blade 2 remains adjusted, there is no possibility that the receiving blade 42b collides with the blade edge and is damaged.

  Further, the receiving blade body 42 is supported by the meat box 3 so that the receiving blade 42b formed at the tip of the receiving blade body 42 is close to the cutting edge of the rotary blade, and it is detected that the operation process is not slicing during operation. It is preferable to provide a sensing means (not shown) for reversing the receiving blade body 42 that separates the receiving blade 42b from the cutting edge of the rotary blade during the non-slicing process.

  In the meat slicer in which the meat box 3 is reciprocally movable in the horizontal direction and slices the block meat M only during the forward stroke of the meat box 3, the sensor detects that the meat box 3 is in the backward stroke. The retracting means of the receiving blade body 42 is composed of a magnet 48 and a proximity switch 49 that move the receiving blade body 42 backward so as to separate the receiving blade 42b from the cutting edge based on the detection result of the sensor. The device 47 may be used.
