Description

  The present invention relates to a meat slicer, and more particularly to improving the safety of a meat supply site in the most widely used type of meat slicer.

  In the most general meat slicer, as shown in FIG. 1 of Patent Document 1 (Japanese Patent Laid-Open No. 2003-170390), the front end surface of the block meat is placed along the rotating surface of a round blade that rotates in a vertical plane. A horizontal reciprocating type in which a meat box containing block meat is reciprocated in the left-right direction on a rail by a crank mechanism. In the meat slicer described in Patent Document 1, the crank mechanism is provided so as to rotate in the horizontal direction directly below the meat box.

  On the other hand, as shown in FIG. 3 and FIG. 4 of Patent Document 2 (Japanese Patent Laid-Open No. 2002-239981), there is also a meat slicer in which a crank mechanism is arranged so as to rotate in the vertical direction at the lower part of the tool mount.

  Even in the meat slicer described in either Patent Document 1 or Patent Document 2, the meat box moves in the left-right direction while being exposed, which is extremely dangerous for the operator. However, the meat slicer described above has been used for a long time, and other parts have been improved. However, the state in which the meat box is exposed is followed as it is and is not yet improved.

  Originally, the operation of this kind of meat slicer itself was a dangerous work, and the workers were trained for a certain period of time, and only those who were called “craftsmen” who had skilled use skills. As a result, the above dangerous situation was rarely regarded as a problem.

  Recently, however, workers have changed to so-called “amateurs” such as inexperienced part-time women and foreign workers who are difficult to communicate, and accidents tend to occur frequently. By the way, according to the statistics of the Ministry of Health, Labor and Welfare, there are 698 accidents caused by cutters and slicers in 2001, but the actual number seems to exceed this, and meat that is highly safe from the meat processing site Slicer development has become highly desirable.

  Under such circumstances, as shown in Patent Document 3 (Japanese Patent No. 3335899), a meat slicer of a type in which a meat box is reciprocated in the vertical direction has been announced as one of safety improvement measures. However, also in Patent Document 3, the meat box is in an exposed state like the meat slicer described above, and the risk of an unexpected accident caused by an operator inadvertently contacting the moving meat box has not yet been resolved. .

  The meat slicer S shown in FIGS. 1 and 2 has a front end face along the rotating surface of the round blade 2 rotating in a vertical plane, and reciprocally moves left and right or up and down along a rail or guide by a crank mechanism. This is a meat slicer S having a known configuration with a box 4. As an improvement in the invention of the original application of the present application, a meat box cover 12 that covers the entire range of the left and right or up and down movement of the meat box 4 is mounted on the machine base 1 of the meat slicer S. In addition, this invention is not restricted to a round blade as a blade which slices meat, It is also possible to use other blades, such as a band blade.

  The configurations of Reference Examples 1 and 2 will be described with reference to FIGS. Here, FIGS. 1 and 2 show a meat slicer S of the type shown in Patent Document 1 in which a crank device for reciprocating the meat box 4 in the left-right direction is arranged so as to rotate in a plane directly below the meat box 4. It is a perspective view.

  A motor (not shown) is installed inside the machine base 1, and the round blade 2 rotating in the vertical plane on the front side of the machine base 1 is driven by the round blade drive motor.

  In addition, there is a ham slicer S of a type in which the meat box 4 is reciprocated in the left-right direction with the round blade 2 and the meat box 4 tilted as appropriate, and a frozen meat slicer S for cutting frozen meat. The present invention can also be applied.

  A meat box drive motor (not shown) is installed in the machine base 1, and a crank (not shown) is rotated on the machine board 1 on a horizontal plane by the meat box drive motor. The meat box 4 is indicated by a broken line in FIG. 2, and the meat box 4 is connected to a crank (not shown) and supported by guide rails (not shown) in the front and rear directions so as to horizontally reciprocate in a fixed section in the left-right direction. To do. With the above configuration, the meat box 4 reciprocates horizontally between the start end position and the slice position.

  Further, as shown in FIG. 2, a meat feed conveyor 5 is provided at the bottom of the meat box 4. A plurality of upper feed rollers 6 and 6 are supported above and supported by a swingable support arm 7 above the meat box 4. The upper feed rollers 6, 6 are in contact with the upper surface of the meat stored in the meat box 4 and take a position for feeding the meat and a position for supplying the raw meat to the meat box 4.

  In Reference Example 1 in FIG. 1, substantially the entire ceiling of the meat box cover 12 is opened, and in Reference Example 2 in FIG. 2, the meat box cover 12 opens a part of the ceiling of the meat box 4. For this reason, the upper feed rollers 6 and 6 can swing between the working position and the upper retracted position that does not hinder the supply of meat into the meat box 4. The meat feeding apparatus is composed of the aforementioned meat feed conveyor 5 and upper feed rollers 6 and 6.

  At the front end of the meat box 4 on the side of the round blade 2, the abutment plate 10 that receives the entire front end of the meat is attached to the machine base 1 so that the position of the meat plate 4 can be adjusted in the meat feeding direction (front and rear direction). This abutment plate 10 is configured to be able to adjust the thickness of a thin piece formed by cutting with a round blade 2 by adjusting with a handle.

  The round blade 2 is supported by a support erected in the vicinity of the front end of the meat box 4 and is rotated at a high speed in a vertical plane by a known drive means (the above-described round blade drive motor). Cut the tip of the meat sent out from the section into thin pieces.

  The structure of the meat box cover 12 in Reference Example 1 configured as described above will be described. The meat box cover 12 according to the present invention is manufactured using a thin plate member such as stainless steel or synthetic resin. In this case, the meat box cover 12 has a large number of rectangular and elliptical shapes on all or part of the meat box cover 12 so that at least the remaining amount of the material placed on the meat box 4 can be monitored from the outside. It is preferable to form a circular or circular opening or use a transparent synthetic resin plate.

  In Reference Example 1 shown in FIG. 1, the meat box cover 12 is configured in a box shape with a plate-like vertical wall so as to wrap around the movement locus of the meat box 4 that reciprocates in the left-right direction. The ground height of the upper edge of the cover 12 (distance from the upper edge of the meat box cover 12 to the floor surface) is high, that is, a dimension in which a human hand cannot touch the movable part of the slicer S. This eliminates the possibility that the hand of a person standing on the floor will come into contact with the meat box 4 including the moving accessory from the open portion of the ceiling of the inner box cover 12, thereby improving safety. That is, in FIG. 1, the ground clearance at the upper edge of the meat box cover 12 is set such that the human hand cannot touch the movable part, so that the human body cannot contact the meat box 4 from the outside. And all (refer FIG. 1) thru | or a part (refer FIG. 2 mentioned later) of the ceiling of the meat box cover 12 are open | released.

  Although only the above structure may be used, in FIG. 1, guide cylinders 1 a perpendicular to the four corners of the machine base 1 are further provided, and the guide columns 12 a of the meat box cover 12 are loosely fitted along the guide cylinder 1 a so as to be able to move up and down.

Two horizontal rods 1c are rotatably supported on the machine base 1, and a gear 1d fixed to both ends of the horizontal rod 1c is engaged with the rack 12b of the guide column 12a described above. A handle 1e for lifting the meat box cover 12 is attached to the end of one horizontal rod 1c. An endless conductive member 1f such as a chain or a toothed belt is stretched between the two horizontal rods 1c.

  With the above configuration, when the handle 1e is manually rotated, the horizontal rod 1c is rotated, and the four gears ld fixed to the horizontal rods lc through the conductive member 1f are simultaneously rotated and meshed with the gear ld. The guide columns 12a are simultaneously moved in the vertical direction via the rack 12b, and the meat box cover 12 is moved up and down. When the meat slicer S is operated, the meat box cover 12 is lowered so that at least the position of the solid line in FIG. 1 covering the meat box 4 is taken, and when the meat box 4 is cleaned and inspected, it is shown by a one-dot chain line to the position where the meat box 4 is exposed. To rise. Further, the meat box cover 12 may be raised when the material is supplied to the meat box 4. In addition, it is preferable to provide a lock device that can fix the meat box cover 12 to each of the operation state position of the slicer S indicated by a solid line and the cleaning / inspection position of the meat box 4 indicated by a virtual line.

  Moreover, the raising / lowering mechanism of the meat box cover 12 is not restricted to what was mentioned above, For example, instead of operating a handle manually, you may operate by a raising / lowering motor or a raising / lowering cylinder, or the head of the meat box cover 12 A winch (both not shown) may be engaged with the hook formed in the above and may be raised and lowered.

  In Reference Example 1, the meat box cover 12 is lifted as it is on the meat slicer S, so that no special place for the meat box cover 12 removed during inspection and cleaning is required, and the meat box 4 is inspected and cleaned. Does not interfere with work.

  Note that at least the meat of the material can be supplied onto the conveyor 5 of the stopped meat box 4 on the vertical wall corresponding to the material supply position to the meat box 4 (starting end position of the reciprocating movement of the meat box 4). It is preferable to provide the opening / closing door 13. That is, on the vertical wall corresponding to the material supply position to the meat box 4, an opening / closing door 13 is provided that can be opened and closed by attaching a hinge 13 a to the upper part, and the opening / closing door 13 is opened and the conveyor 5 of the meat box 4 is stopped. The meat of the material can be supplied from a relatively low position. The open / close door 13 is also preferably made of a member that allows the inside to be seen through.

  Moreover, the vertical wall which faces the round blade 2 among the vertical walls which form the meat box cover 12 displays a portion corresponding to the round blade 2 and the abutting plate 10 in FIG. Such a shape is appropriately cut out.

  The plate-like vertical wall forming the meat box cover 12 is formed by bending between the four corner guide posts 12a or by suitably attaching a thin plate having rigidity such as metal or synthetic resin between the four guide posts 12a. It is preferable to hold. In the embodiment, the vertical wall facing the open portion of the ceiling is appropriately bent with the width dimension inward for reinforcement.

  Each vertical wall is not shown in the figure so that it can be easily detached and attached to facilitate cleaning and inspection of the meat box 4, but it is screwed with a plurality of threaded knobs or a connecting member ( It is preferable that each of the vertical walls connected in a frame shape is hooked on the connecting member and attached to the connecting member. Further, each vertical wall may be an open / close door like the above-described open / close door 13. In addition, each vertical wall can be formed in a lattice shape made up of a large number of thin frames, or a wire mesh that does not contain a fingertip can be used.

  In addition, each vertical wall is formed of a flexible material such as canvas, and can be easily detached using a hook or hook fastener called Magic Fastener (registered trademark). It is convenient to roll up a part if necessary.

  Furthermore, for safety, an interlock for safety is provided such that the operation cannot be performed when the above-described vertical wall or the open / close door 13 is opened.

  On the other hand, also in the reference example 2 shown in FIG. 2, the ground height of the upper edge of the meat box cover 12 is set so that the human hand cannot touch the movable part, and at least at the stop position (material supply position) of the meat box 4. The ceiling of the corresponding meat box cover 12 is open, but the human body cannot come into contact with the outside except the area covered by the machine base 1, the abutment plate 10, the round blade 2 and the like in the movement range of the meat box 4. Enclose as In this way, at the stop position (material supply position) of the meat box 4, the upper feed roller 6 supported by the swingable support arm 7 attached to the meat box 4 is placed on the conveyor 5. It can be retreated to an upper retreat position (position shown in FIG. 2) that does not hinder supply.

  In Reference Example 2 shown in FIG. 2, as in Reference Example 1 in FIG. 1, the stop position (material supply position) of the meat box 4 of the meat box cover 12 is an opening that can supply material from a relatively low position. An open door 13 is provided. Similarly to the first embodiment shown in FIG. 1, in the second embodiment shown in FIG. 2, the meat box cover 12 may be raised to a state where the meat box 4 is exposed.

  Next, an embodiment of the present invention will be described with reference to FIGS. According to the present invention, unlike the reference examples 1 and 2, the meat box cover 12 is supported by the support member 21 different from the meat slicer S. FIG. 3 is a front view of one embodiment of the present invention, and FIG. 4 is a perspective view for explaining a procedure for mounting the meat box cover 12 of the embodiment shown in FIG. 3 on the meat slicer S. FIG. 5 is a side view of the embodiment shown in FIG. 3, and FIG. 6 is a perspective view of the meat box cover 12 of the embodiment shown in FIG.

  In FIG. 3, the meat slicer S is indicated by a virtual line. Also in the present embodiment, the meat slicer S is a known one, and includes a meat box 4 that reciprocates horizontally along the rotation surface of the round blade 2. A support member 21 different from the meat slicer S is provided, and a meat box cover 12 covering the meat box 4 is supported by the support member 21 over the entire movement range of the meat box 4.

  For example, as shown in FIG. 6, the support member 21 in the present embodiment is configured in a frame shape using an appropriately sized square tube steel material or a round tube steel material. That is, the support member 21 includes a U-shaped meat box cover holding portion 21a, and the meat box cover holding portion 21a winds around the lower part of three sides except for the front (round blade 2 side) of the meat box cover 12. Thus, the meat box cover 12 is held. The leg portion 21c is formed in a U-shape with the front open like the holding portion 21a. A connecting portion 21d, which is an H-shaped vertical member, is connected to the meat box cover holding portion 21a by welding or the like, and the leg portion 21c is connected by welding or the like via the connecting portion 21d.
