Description

  The present invention relates to a meat slicer. More specifically, the present invention relates to an improvement of a meat slicer of a type using a round blade, which is currently most frequently used for slicing a meat block mainly in a chilled state (product temperature around 0 ° C.).

  Ham slicers that slice cylindrical ham at room temperature are often found in retail butcher shops. This has a structure disclosed in, for example, Patent Document 1 (Japanese Utility Model Publication No. 37-29973).

  That is, in the ham slicer disclosed in Patent Document 1, a rotating blade is pivotally supported at one corner of the machine so as to rotate on an inclined line at an arbitrary angle with respect to the axis of the machine, and the surface of the rotating blade. The bucket is provided at the tip of the swing rod pivotally supported on one side of the machine by a shaft, and the crank provided at the tip of the rotary shaft installed on the machine The arm is connected with a connecting rod.

  In a ham slicer, a substantially cylindrical ham is sliced at room temperature, so that the rotating blade and the contact plate are uniformly inclined in the same direction as in Patent Document 1, and the object to be cut (ham on the inclined line) ) Is moved by the swinging motion of the bucket. The bucket is inclined in the opposite direction of the rotary blade by bending a square plate into an L shape and contacting the side end of the square plate with the rotary blade. For this reason, the ham contained in the ham is also inclined, and in order to sequentially cut the lower ends thereof, the feeding operation of the raw ham is performed by the weight of the ham itself, and the wall surface of the bucket is automatically scraped down. . Therefore, the feeding operation is simple. At the same time, the ham is cut with a rotating blade when the bucket is moved upside-down by a swing rod, so that the ham tends to be lifted by the bucket wall, so that the ham is in pressure contact with the bucket wall. Therefore, a simple squeeze that can be pressed lightly without requiring a strong hum suppression mechanism as in the prior art is sufficient, and therefore the operation of the machine is extremely easy.

  However, when the apparatus of Patent Document 1 is used when slicing a meat block in a chilled state (a product temperature of around 0 ° C.) targeted by the present invention, there are the following problems.

  Because the ham slicer slices the cylindrical ham at room temperature, by tilting the meat box, the ham automatically rolls down the wall surface of the meat box toward the blade surface of the round blade due to the weight of the ham itself. However, in the chilled meat block targeted by the present invention, the meat block may rise to a positive temperature during slicing, and not only it becomes soft but also becomes sticky and adheres to the wall surface. , Slipping worse. Therefore, there is a problem that the meat block does not rub down the wall surface of the meat box smoothly and smoothly only by tilting the meat box. In addition, the problem that the slice thickness is not stable due to poor sliding occurs.

  Furthermore, since the ham sliced with the ham slicer is relatively light, the ham slicer is also relatively light and can be used with its inclination. On the other hand, when slicing chilled meat blocks, the weight of the meat block and the meat box is also large, and when such a slicer is tilted, a mechanically hitting part occurs, and as it is used, Wear occurs unevenly (over time) and looseness occurs.

  In particular, if rattling occurs in the shafts that support the rocking rods and the nodes of the crank mechanism, the entire bucket is inclined with the shaft as the center, and the tip of the meat block (ham) mounting surface located at the bottom is the plate. Approaching. Therefore, the front end surface of the bucket cannot swing back and forth while maintaining a parallel state with respect to the round blade, and the slice thickness is not the same. Further progress may lead to an accident in which the bucket tip collides with the round blade.

  When slicing a chilled soft meat block with an inclined ham slicer, the tip of the meat block moves while being pressed strongly against the plate and the round blade surface by the weight of the meat block itself, so the surface is rubbed and damaged In addition, scrap meat sticks to the cut surface and deteriorates the quality.

  Considering such problems, as a typical meat slicer currently used when slicing a meat block in a chilled state (a product temperature of about 0 ° C.), for example, a patent As shown in FIG. 1 of Document 2 (Japanese Patent Application Laid-Open No. 2003-170390), the round blade is rotated around the horizontal axis in the vertical plane, and the front end surface of the meat box is along the rotation plane of the round blade, There is a horizontal reciprocating-type slicer in which a meat box is linearly reciprocated on a rail by a crank mechanism and a bottom conveyor is provided at the bottom of the meat box to feed a meat block toward the front end of the meat box.

  In the meat slicer disclosed in Patent Document 2, the meat box linearly reciprocates on the rail. However, play is likely to occur between the rail and the contact surface of the meat box. As a countermeasure, when the play is restricted, not only the movement of the meat box is deteriorated, but also the frictional resistance on the contact surface is increased and the required power is increased. For this reason, it is difficult to keep the positional relationship between the front end face of the meat box and the cutting edge of the round blade constant. In particular, it is effective to make the gap between the front edge of the meat box and the cutting edge of the round blade as small as possible in order to reliably cut soft raw meat (chilled state) and meat with many muscles. There was a limit to reducing the gap in a meat box that moved back and forth linearly on the rail and had a lot of looseness.

  Furthermore, the occurrence of the above-mentioned play also causes the vibration and noise of the meat slicer and worsens the working environment.

  Further, in the horizontal reciprocating type slicer in which the meat box is linearly reciprocated on the rail as described above, side wall plates are erected on the left and right side ends of the meat box. When supplying the meat block of raw material to the worker, the worker lifts the meat block and passes over the upper edge of the side wall plate located on the right side of the side wall plate as viewed from the front end of the meat box and above the meat box. It had to be thrown in and the burden on the operator was great.

  Further, in the conventional meat slicer, the reciprocating meat box remains exposed, which is dangerous.

  In view of the current situation as described above, the applicant supports the meat box in the horizontal direction around the swinging shaft extending in the vertical direction in Patent Document 3 (Japanese Patent Laid-Open No. 2006-35349). Therefore, we have developed and proposed a meat slicer that uses a band knife that moves the meat box back and forth without the need for rails. However, since the device of Patent Document 3 uses a band knife, the configuration is complicated, and special consideration is required for adjustment and maintenance.

The present invention solves the problems associated with a meat slicer having a meat box that linearly reciprocates on the rail described in Patent Document 2 described above, and prevents the occurrence of play when the meat box is moved. Less, can keep the positional relationship between the front end face of the meat box and the cutting edge of the round blade, especially soft raw meat and meat block with a lot of muscles can be reliably cut, Meat slicer that has less vibration and noise from the meat slicer, can easily supply meat blocks into the meat box, and uses a round blade as the cutting blade for easy adjustment, maintenance, and safe operation The purpose is to provide.
Japanese Utility Model Publication No. 37-29973 JP 2003-170390 A JP 2006-35349 A

In order to achieve the above-mentioned object, the present invention provides a horizontal shaft that is pivotally supported at the front upper end position of the aircraft, a round blade that is attached to the horizontal shaft and rotates in a vertical plane around the horizontal axis, A horizontal support shaft disposed parallel to the horizontal axis near the bottom of the machine body at a lower position, a swinging body swingable about the axis of the horizontal support shaft, and a crank connected to the swinging body to reciprocate. Supported by the apparatus and the rocking body, reciprocally rocks on the circular arc surface centering on the axis center between the start end position and the end position while keeping the front end face along the rotation surface of the round blade. It consists meat boxes, meat box side wall panels erected on the left and right side ends, made from the top feeder comprising a bottom conveyor and with projections rollers provided at the bottom, meat box at the starting end position, the meat It is arranged to be the lowest position in the reciprocating movement of the box Are inclined outwardly, that the side wall plate placed on meat blocks lean the side conveyor belts for feeding toward the front end of the meat box meat blocks in phase with said bottom conveyor is stretched A featured meat slicer.

  In the present invention, the axis of the horizontal support shaft of the rocking body is located on the left outer side of the vertical lower position of the horizontal shaft to which the round blade is attached, and when viewed from the front end of the meat box It is preferable that the meat box swings toward the right side of the round blade while always drawing a downward-sloping swing locus.

  In the ham slicer disclosed in Patent Document 1, since the bucket is arranged so as to swing substantially vertically with respect to the round blade, the loaded material (ham) is placed on the bottom surface (the hams in FIG. 3 are juxtaposed. There is a problem that the weight does not act on a wide surface) and the surface is lifted from the bottom surface of the bucket by centrifugal force and is not stable. On the other hand, in the embodiment of the present invention, as will be described later with reference to FIG. 1, the meat box swings downward from the substantially horizontal state, so that the weight of the meat block is applied to the bottom of the meat box, and the centrifugal There is little lift of the meat block due to force, and it is stable. Furthermore, in the present invention, since the feeding device is provided on the bottom surface of the meat box, in this embodiment, more stable feeding is possible by the joint action of both.

  Further, in the present invention, a side conveyor belt for feeding the meat block toward the front end of the meat box at least on the right side wall end of the meat box as viewed from the front end of the meat box on the meat block mounting surface of the meat box. It is desirable to stretch.

A meat box cover that covers the meat box over the entire range of reciprocal rocking of the meat box is supported by the machine body, and the upper surface of the meat box cover is stopped at the start position of the reciprocating rocking of the meat box. A supply port having a width capable of supplying at least a raw meat block at a position facing the block meat mounting surface of the meat box inclined outward is opened in the meat box cover, and the opening of the supply port It is preferable that the meat slicer has a size that can close the opening and is provided with a supply port cover that can be seen from the outside so as to be opened and closed.

  The meat box is disposed at the start end position of the reciprocating swing so as to be the lowest position in the reciprocating swing range of the meat box, and at the start position, the position opposite the block meat placing surface that is stopped. It is preferable that the supply port be opened.

  In the present invention, the round blade rotates in a vertical plane around the horizontal axis at a fixed position, and is supported so as to be swingable about the axis of the horizontal support shaft attached to the bottom of the machine body. A meat box having a feeding device is provided on the semi-axial center side of the rocking body, and the meat box is configured to reciprocate between the start end position and the end position while keeping the front end face along the rotation surface of the round blade. Therefore, compared to a device using rails such as the conventional device described in Patent Document 2, the occurrence of rattling is remarkably small, and the movement of the meat box becomes extremely smooth.

  Moreover, in this invention, the feed apparatus which consists of a bottom part conveyor which sends a meat block toward the front end of a meat box is provided in the bottom part of the meat box, and it sends out by dead weight like the ham slicer of patent document 1 Compared to the above, stable feeding is possible.

  In the ham slicer described in Patent Document 1, since the bucket is arranged so as to swing substantially vertically with respect to the round blade, the mounted material (ham) is the bottom surface (the ham in FIG. 3). The self-weight does not act on the wide surface), and it is lifted from the bottom surface of the bucket by centrifugal force and is not stable.

  On the other hand, in particular, the axis of the horizontal support shaft of the oscillator according to the present invention is located on the left outside of the vertical lower position of the horizontal shaft to which the round blade is attached, and the meat box is always lowered to the right. If the meat box swings toward the right side of the round blade while drawing the swing path, the meat box swings downward from the substantially horizontal state, so that the weight of the meat block is at the bottom of the meat box. The meat block is not lifted by the centrifugal force and is stable. In addition, since the meat block placed in the meat box is sliced on the right side of the round blade, it becomes the same as the slicing operation in the conventional slicer in which the meat box reciprocates left and right, and it is easy to take out the sliced meat pieces manually Yes.

  In addition, when the meat block of the meat box is placed on the mounting surface of the meat box, a conveyor belt for feeding the meat block toward the front end of the meat box is stretched at least on the right side wall plate as viewed from the front end of the meat box. Even if the meat block leans against the right side wall, it is sent out reliably.

Furthermore, in the present invention, a meat box cover that covers the meat box over the entire reciprocating swing range of the meat box is supported by the machine body, and the meat box is stopped at the start position of the forward swing of the meat box. A supply port having a width capable of supplying at least the meat block of the raw material is opened in the meat box cover, the opening of the supply port has a size capable of closing the opening, and the inside from the outside When the supply port cover that can be seen through is provided so as to be openable and closable, the supply operation of the meat block as a raw material to the meat box can be performed safely and easily.

  In addition, the meat box is disposed at the lowest end position in the reciprocating swing range of the meat box at the start end position of the reciprocating swing, and the position facing the stopped block meat placement surface at the start end position. In addition, when the supply port is opened, the supply operation of the meat block serving as the raw material to the meat box can be performed more easily.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing embodiments of the present invention. 1 is a front view of an embodiment according to the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a plan view.

  The machine 1 of the meat slicer of the present embodiment is configured as a box, and as shown in FIGS. 1 to 3, the meat box 5, the swinging body 9 that supports the meat box 5, and the crank device that reciprocates the meat box. 16 is housed.

  A blade support 2 is projected upward on the front surface of the machine body 1 made of a box, and a horizontal shaft 3 is pivotally supported on the blade support 2, and a round blade 4 is fixed to the horizontal shaft 3. . The round blade 4 is configured to rotate in the vertical plane around the horizontal axis 3 by a motor 24 as in the conventional meat slicer.

  Next, a configuration related to the reciprocating swing of the meat box 5 which is a main component of the present invention will be described in detail. As shown in FIG. 1, near the bottom of the round blade 4 of the machine body 1, the rocking body 9 can be swung to a position on the left outer side of the vertical lower position of the horizontal shaft 3 to which the round blade 4 is attached. A horizontal support shaft 13 is provided for support.

  The swinging body 9 that supports the meat box 5 includes a mounting base 10 on which the meat box 5 is mounted, fan-shaped front and rear frames 11 and 11 that extend downward from the front and rear portions of the mounting base 10, and the front and rear frames, respectively. 11 and 11 and a hollow connecting tube 12 (see FIG. 2) for connecting and fixing the leading ends of the sector shape, and the rocking body 9 has a strong structure.

  As shown in FIG. 2, the horizontal support shaft 13 passes through the hollow portion of the connecting pipe 12 constituting the rocking body 9. Here, the horizontal support shaft 13 is extended as much as possible to the inner width dimension of the machine body 1 (the dimension appearing in FIG. 2), and the front end of the meat box 5 supported by the rocking body 9 and the cutting of the round blade 4 are performed. The gap with the cutting edge is accurately maintained.

  Further, as shown in FIG. 2, both ends of the horizontal support shaft 13 are fixed by the fixtures 14 and 14 so as to be parallel to the horizontal shaft 3 to which the round blade 4 is fixed while maintaining the horizontal state at the bottom of the body 1. ing. An appropriate bearing member such as a ball bearing is used for the fitting portion between the connecting pipe 12 and the horizontal support shaft 13 so that there is no play as much as possible, and the swinging body 9 can swing smoothly.

  While the front end surface (left end surface in FIG. 2) of the meat box 5 is aligned with the rotation surface of the round blade 4, the meat box 5 is pivoted by the crank device 16 about the axis of the horizontal support shaft 13 in FIG. 1. It can be swung back and forth on a horizontal arc surface centered on the center.

  The crank device 16 is equipped to reciprocate a predetermined range of the meat box 5 mounted on the rocking body 9 around the axis of the horizontal support shaft 13, and is connected to a part of the rocking body 9. The connecting rod 17 includes a driving motor 25, a reduction gear 26, a clutch 27, and the like installed on the bottom of the machine body 1 connected to the other end of the connecting rod 17. A servo motor may be used as the drive motor 25. Since the crank device 16 itself has a known structure, details are omitted.

  The swing range of the meat box 5 is a position where the front end surface of the meat box 5 is disengaged from the rotating surface of the round blade 4 as viewed from the front end of the meat box 5 (in the state shown in FIG. 1) (the broken line in FIG. 1). The position where the front end surface of the meat box 5 overlaps the rotation surface of the round blade 4 (the position indicated by the two-dot chain line in FIG. 1) is the end position. That is, the meat box 5 reciprocally swings around the axis of the horizontal support shaft 13 as a swing range between the start position and the end position.

  By starting the operation by supplying the meat block 5 to the meat box 5 at the start position, the front end portion of the meat block sent out from the front end of the meat box 5 is moved by the swinging movement of the meat box 5. It is pressed against the right side and sliced, cut into sliced meat pieces at the end position, directly received by the operator's hand, and appropriately placed in a saucer or the like.

  The meat box 5 is basically configured in the same manner as a conventional meat slicer, with the meat block placed on the bottom, which is the placement surface of the meat block, facing forward (round blade 4 side). A bottom conveyor belt 6 to be fed out is stretched (from the back side to the near side in FIG. 1, from right to left in FIG. 2, and from top to bottom in FIG. 3). It is moved intermittently by appropriate means.

  As seen from the front end of the meat box 5 (that is, in the state of FIG. 1), the meat box 5 may be formed in a bowl shape by standing side wall plates on the left and right side ends as in the conventional type. In the present embodiment, the left side wall plate is not directly related and is not shown.

The side wall plate 7 erected on the right end of the meat box 5 is conventionally made of a plate material. However , in the present invention , the side conveyor belt 8 is the same as the bottom conveyor belt 6 stretched on the bottom. It is configured by stretching. The side conveyor belt 8 is provided with appropriate driving means so that it can move in synchronism with the bottom conveyor belt 6, and is moved in synchronism mechanically or electrically by a known method.

  Further, the side wall plate 7 on which the side conveyor belt 8 is stretched does not necessarily have to be in an upright state (the state shown in FIG. 1) with respect to the bottom conveyor belt 6, so that the upper part is expanded outward as appropriate. You may make it incline.

Further, the bottom conveyor 6 and the side conveyor 8, when the meat box 5 is stopped at the start position (dashed position shown in FIG. 1), a servo motor so that the placed meat block is fed by a predetermined amount ( It is preferable to drive using a not-shown). In the present embodiment, due to the above-described configuration, the meat box 5 is inclined outwardly at the start position as shown in FIG. 1, and the placed meat block leans against the side conveyor belt 8. Since it is in a state, it can be reliably delivered. The bottom conveyor 6 and the side conveyor 8 may be roller conveyors.

  A receiving blade body (not shown) adjacent to the cutting edge of the round blade 4 is provided at the leading end of the conveyor belts 6 and 8 in the same manner as a conventional similar device. It is provided continuously along.

  In the meat box 5, as in the conventional type, an upper feed device composed of a roller with a protrusion or the like, or a presser device that presses the upper surface of the meat block when the meat block is sliced, is operated at the upper position of the meat box 5. May be provided so as to be able to be switched to a retreat position for facilitating the supply of the meat block by opening, but is not shown in the present embodiment.

  In addition, although the detailed illustration is omitted, the front plate of the meat box 5 is in contact with the front end surface of the meat block to be sent out and adjusted in the front-rear direction to determine the slice thickness as in the conventional type It is attached to.

  As shown in FIGS. 1 to 3, a cover 1 b formed of a thin plate is appropriately provided on the upper portion of the machine body 1 so as to cover the upper surface of the machine body 1, and the meat box over the entire reciprocating range of the meat box 5. 5 is covered. The meat box cover 1b is provided with a supply port, and this supply port has a width that can supply at least raw meat blocks to the meat box 5 that is stopped at the start position of the reciprocating motion of the meat box 5. That is, the supply port is inclined so as to follow the meat box 5 at a position facing the meat block placement surface of the meat box 5 that is stopped at the start position of the swing movement as shown in FIG. It is formed in the upper surface of the cover 1b, and the supply port has a width corresponding to the meat block placement surface.

  A supply port cover 1a is attached to the meat box cover 1b through a hinge 1c so as to be openable and closable at the opening of the supply port. Here, the supply port cover 1a has a size that can close the opening, and can be seen from the outside. That is, in the illustrated embodiment, as shown in FIG. 2, the cover 1a is formed of a thin plate, and the thin plate is provided with a number of watermark holes 1d that are sized to prevent intrusion of fingers. However, the configuration of the cover 1a that allows the inside to be seen from the outside is not limited to the mode shown in FIG. 2. For example, the cover 1a is configured in a fence shape using a large number of thin bar members, and the cover 1a May be formed of a transparent material such as a hard resin.

  In order to facilitate the supply of the meat block to the meat box 5 at the starting position when the meat box 5 reciprocally swings, the meat is placed at the lowest end (the position indicated by the broken line in FIG. 1) in the reciprocating swing range of the meat box 5. While the box 5 is positioned, the supply port is opened at the upper surface position of the meat box cover 1b facing the block meat placement surface of the meat box 5 that is stopped at the start position.

  As described above, the swinging body 9 that supports the meat box 5 is tilted around the axis of the horizontal support shaft 13 provided at the bottom of the machine body 1 below the round blade 4 (see FIG. 1 is moved in a swinging manner from the substantially upright state (the position of the two-dot chain line shown in FIG. 1) where the front end surface of the meat box 5 overlaps with the round blade 4 from the position of the broken line shown in FIG.
