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 common meat slicer, as shown in FIG. 1 of Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-170390), the front end face of meat is aligned with the rotating surface of a round blade rotating in a vertical plane, and the meat is It is a horizontal reciprocating movement type in which a meat box containing a box is reciprocated in a horizontal direction on a rail provided on a machine base 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 to rotate in the vertical direction at the lower portion of the tool mount.

  In the meat slicer described in any of Patent Document 1 and Patent Document 2, the meat box moves in the left-right direction while being exposed, so that the operator who directly operates the meat slicer is in the vicinity. It is a dangerous state that is liable to cause contact accidents with third parties other than workers.

  In particular, the portion protruding from the machine base toward the anti-round blade side at the end of the meat box on the side of the anti-round blade is more easily approached by the third party than other moving parts of the meat box. Accidents are likely to occur when the end of the anti-circular blade in a state of protruding from the base of the meat box that suddenly moves and a part of the body of a third party come into contact.

For the purpose of drastically improving the safety of the meat slicer as described above, the applicant of the present invention relates to a meat slicer provided with a meat box cover that covers the entire movement range of the meat box. Although proposed in Japanese Patent Application No. 2006-205810, covering the entire movement range of the meat box with the meat box cover improves safety, but on the other hand increases the size of the machine and increases costs. In addition, there was a problem that the meat box cover interferes with cleaning and maintenance after work.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings illustrating embodiments of the present invention.

  In the meat slicer according to the present invention, a meat box containing meat is placed in a horizontal direction on a rail provided on a machine base by a crank mechanism along a front end surface of the meat along a rotating surface of a round blade rotating in a vertical plane. The meat box is in a state in which the end of the meat box on the side opposite to the round blade protrudes from the machine base. As an improvement, a protective guard that surrounds the end of the meat box on the side opposite to the round blade is provided only for the range of movement of the protruding portion from the machine base.

  The configuration of an embodiment of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a first embodiment in which the present invention is applied to a meat slicer of the type shown in Patent Document 1 in which a crank device for moving a meat box to the left and right is arranged to rotate in a plane directly below the meat box. 2 is a side view, and FIG. 2 is a plan view of a main part in which the details of FIG.

  FIG. 3 is a side view of an essential part in which details of the second embodiment implementing the invention of claim 3 are omitted, and FIG. 4 is a plan view of FIG.

  FIG. 5 is a side view of an essential part in which details of the third embodiment implementing the invention of claim 4 are omitted, and FIG. 6 is a plan view of FIG.

  First, with reference to FIG. 1 and FIG. 2, the structure of the meat slicer which is a common part in a 1st Example to a 3rd Example is demonstrated.

  A motor (not shown) is installed inside the machine base 1, and a round blade 3 that is supported by the tool mount 2 provided on the machine base 1 and rotates in a vertical plane is installed at the lower part of the tool mount 2. (Not shown). Further, a crank (not shown) is rotated on a horizontal plane by another motor (not shown) installed in the machine base 1, and the left and right directions are supported by guide rails 4 and 4 on the machine base 1 in the left-right direction. A meat box 5 that reciprocates horizontally in a certain section (arrow right-left in FIG. 2) is connected to a crank. With the above-described configuration, the meat box 5 has a position on the right end of the arrow shown in FIG. 2 (a position at which the meat box 5 is indicated by a solid line) and a position on the left end of the arrow (the auxiliary meat mounting table attached to the meat box 5). 8 is moved back and forth horizontally until a part of 8 is displayed).

  In this case, the anti-round blade side end portion of the meat box 5 is in a state of protruding from the machine base 1 toward the anti-round blade side. That is, the portion of the meat box 5 near the end on the side opposite to the round blade (on the right side in FIG. 1) protrudes away from the wall surface 1a of the machine base 1 as shown in FIG.

  In addition to this, there is a known frozen meat slicer (not shown) that reciprocates the meat box 5 in the left-right direction with the round blade 3 and the meat box 5 tilted as appropriate. Adaptable.

  A meat feed conveyor 6 is provided at the bottom of the meat box 5. In addition, a plurality of upper feed rollers 7 and 7 are provided above the meat box 5. The upper feed rollers 7, 7 are in contact with the upper surface of the meat stored in the meat box 5, so that the working position for feeding the meat toward the round blade 3 (the phantom line display position in FIG. 1) and the upper retracted position (see FIG. 1 (solid line display position).

  On the anti-round blade side end surface A of the meat box 5, an auxiliary meat mounting table 8 is provided so as to extend in a direction away from the anti-round blade side end surface A in a substantially horizontal direction. The auxiliary meat placing table 8 is detachable so that the meat box 5 can be switched between the extended state and the original state. However, the auxiliary meat placing table 8 may remain fixed. .

  The anti-round edge side end surface A means the anti-round edge side (right direction in FIG. 1) final end face of the meat box 5. Therefore, when the auxiliary meat placing table 8 is in the state in which the meat box 5 is extended, the anti-round blade side end surface A becomes the final end surface 8a of the auxiliary meat placing table 8 in the anti-round blade side direction.

  In FIG. 1 and FIG. 2, the auxiliary meat loading table 8 having a bowl-like shape in which a meat loading portion is formed at the bottom and both sides in the moving direction are erected and opened upward is provided on both sides in the feeding direction of the meat feed conveyor 6. The side wall plates 9 and 9 which are erected on the side wall are overlapped with each other and are integrally attached by bolts 10 and 10, but the auxiliary meat placing table 8 can be removed as necessary.

  Although the illustration of the auxiliary meat placing table 8 is omitted without removing the auxiliary meat placing table 8, the auxiliary meat placing table 8 can be switched between the extended state of the meat box 5 and the original state by a known means. The base 8 may be swingably attached to the anti-blade side end surface A of the meat box 5 so as to be switchable between a substantially horizontal position where the meat box 5 is extended and a vertical position where the meat box 5 is raised.

  Usually, an operator who operates such a type of meat slicer is standing alone at the position of the start side of the meat box 5 on the side of the round blade, so that the operator is at a position opposite to the operator. It is difficult to pay attention to the vicinity of the end of the meat box 5 on the side of the anti-round blade.

  In particular, the auxiliary meat loading table 8 is configured in such a manner that the end surface A on the side of the cut blade side of the meat box 5 extends from the meat box 5 in a substantially horizontal direction and protrudes from the machine base 1 toward the anti-round blade side. In the case (the state shown in FIG. 1), the anti-blade side end face 8a of the auxiliary meat placing table 8 is located far from the wall surface 1a of the machine base 1, and the meat box 5 shown in FIG. The corner formed by the left side wall surface 8b of the auxiliary meat placing table 8 and the wall surface 1a of the machine base 1 is a danger zone B, and a person other than an operator who drives a slicer in the vicinity of the danger zone B. Part of the body of a third party is likely to invade, resulting in a high risk of contact accidents.

  The present invention was made for the purpose of preventing accidents of human contact near the end of the anti-round blade side of the meat box 5 where it is difficult for the operator operating the meat slicer to reach as described above. In particular, an attempt is made to prevent inadvertent entry of the body into the danger zone B described above.

  Therefore, in the first embodiment, as shown in FIG. 1 and FIG. 2, a protective guard 11 that surrounds the movement range of the anti-round blade side end surface A in the meat box 5 is installed.

  In particular, when the auxiliary meat placing table 8 is extended in a direction substantially away from the anti-blade side end surface A of the meat box 5 as described above, the danger zone B is formed widely, so that a contact accident occurs. Is likely to occur. At this time, the necessity of the protective guard 11 is high.

  The protective guard 11 in the first embodiment is composed of a plate-like vertical wall 12. The vertical wall 12 in the first embodiment is formed of a rectangular flat plate so as to be able to surround the moving range of the anti-blade side end surface A of the meat box 5, and the lateral wall (the moving direction of the meat box 5, that is, in FIG. 2). The arrow (left and right direction) is a dimension that exceeds the movement range of the meat box 5, and the vertical direction (vertical direction) is a length dimension that can enclose the anti-blade side end surface A of the meat box 5. Therefore, the vertical wall 12 surrounds and shields the moving range of the anti-blade side end surface A of the meat box 5, thereby preventing contact with the human body.

  In the first embodiment, the vertical wall 12 has a simple flat plate shape, but may be appropriately deformed, for example, by bending the periphery of the flat plate toward the machine base 1 for reinforcement.

The vertical wall 12 is formed of a relatively thick and rigid material using a lightweight material such as resin or aluminum, but may be formed by appropriately reinforcing using a thin stainless steel plate or the like. good.
In addition to using a transparent material so that the inside can be seen through, it is also possible to use it by selecting a suitable material such as a plate material or a mesh plate with a lot of fine bar holes or a lattice shape using a lot of thin bar materials ( Not shown).
Alternatively, the vertical wall 12 may be configured with a frame-like frame (not shown), and a flexible resin film or cloth may be attached to the frame.

  An opening / closing port through which meat can be supplied from the end face on the side opposite to the round blade of the stopped meat box 5 is provided at the start position of the vertical movement 12 of the meat box 5 in the reciprocal movement. An opening / closing door 16 for closing the opening is attached to the vertical wall 12 by hinges 17 and 117 at the opening / closing opening. The virtual line display of FIG. 1 shows a state where the opening / closing door 16 is opened. Normally, meat is supplied from above the meat box 5, but it is particularly convenient to insert pork loin or the like having a long dimension in the feeding direction through the opening / closing port.

  The vertical wall 12 is detachably attached to both sides of the machine base 1 via support frame bodies 13 integrally connected to the vicinity of both ends of the vertical wall 12 in the moving direction of the meat box 5.

  The support frame 13 has a contact portion that is located near both ends of the vertical wall 12 and is connected to the vertical wall 12 by bolts (not shown) using a bar material (bar-shaped material) such as a thin-walled steel pipe. It consists of two bar members 13a and 13a on the left and right with respect to the feeding direction of the meat in the L-shaped meat box 5, and a connecting bar member 13b that connects the two bar members.

  The ends of the left and right bar members 13a, 13a (the machine base 1 side) are extended, inserted into holding tubes 14 and 14 attached to the left and right side parts of the machine base 1, and fixed with a lock screw 15. Is done.

  By comprising as mentioned above, the space | interval C of the wall surface of the vertical wall 12 which comprises the protection guard 11, and the anticircle edge side end surface A (8a) of the meat box 5 is adjustable. That is, if the lock screw 15 is loosened to change the insertion allowance of the two left and right bar members 13a, 13a constituting the holding frame 13 into the holding tubes 14, 14, the vertical wall 12 feeds meat. Since it moves in the direction, the distance C can be adjusted freely.

  Therefore, the auxiliary meat placing table 8 is removed from the state in which the auxiliary meat placing table 8 is mounted on the anti-round blade side end surface A of the meat box 5 and the anti-round blade side end surface A is extended, or the vertical is raised. When the state is switched to the original state, the distance C between the wall surface of the vertical wall 12 and the anti-round edge side end surface A is a dimension suitable for each state (for example, the protective guard 11 shown in FIG. To the position indicated by the virtual line). The normal interval C is adjusted to such a dimension that a person cannot accidentally insert his / her hand from above the protective guard 11.

  Further, among the two left and right bar members 13a, 13a constituting the support frame 13, the bar member is located on the left side (the left side of the arrow shown in FIG. 2 when the meat box 5 is reciprocated, the upper side in FIG. 2). Reference numeral 13a denotes an auxiliary protective guard (described later) that blocks the danger zone B.

  After the slicing operation is completed, if the lock screw 15 is loosened and the support frame 13 is removed, the protective guard 11 can be removed as a single unit, which does not hinder the cleaning or inspection of each part.

  Next, a second embodiment will be described with reference to FIGS.

  The meat slicer in the second embodiment is the same as that used in the first embodiment. Therefore, in FIG. 3 and FIG. 5, the details of the meat slicer are omitted, and only a part of the outline is displayed.

  In the second embodiment, the protective guard 11 is formed by bending a square plate 18 into a dogleg shape. That is, as shown in FIG. 3, the vertical wall 18 a surrounding the movement range of the anti-round blade side end surface A in the meat box 5 and the movement of the bottom surface of the anti-round blade side end portion protruding from the machine base 1 of the meat box 5. A cross-sectional shape formed by the inclined wall portion 18b surrounding the range and parallel to the meat feeding direction is formed in a dogleg shape as shown in FIG.

  As described above, the guard guard 11 having a cross-sectional shape of the U-shape is along the side view shape (the shape shown in FIG. 3) of the protruding portion from the machine base 1 at the end of the anti-round blade side of the meat box 5. Since it surrounds over the whole moving range of an anti-round blade side edge part, a contact with the person who exists in the circumference | surroundings is prevented.

  Other configurations are the same as those in the first embodiment, and thus description thereof is omitted.

  Next, a third embodiment will be described with reference to FIGS.

  Since the third embodiment has the same configuration as that of the second embodiment described above, only the configuration different from the second embodiment will be described.

  In the third embodiment, the auxiliary meat on the end of the anti-blade side of the meat box 5 on the terminal end position (the position on the left side of the arrow in FIG. 2) of the protective guard 11 in the second embodiment when the meat box 5 is reciprocated. An auxiliary protective guard 11a surrounding the left side surface 8b of the mounting base 8 is extended from a side end portion of the protective guard 11, and is formed in a second shape in plan view.

  The auxiliary protective guard 11a is symmetrical to the auxiliary protective guard 11a provided at the above-mentioned left position on the side of the starting end position (the position on the right side of the arrow in FIG. 2) when the opposite meat box 5 is reciprocated as necessary. Can be provided.

  Providing the auxiliary protective guard 11a as described above has an effect of preventing the body from entering the danger zone B.
