Description

[Technical field]

[0001] The present invention relates to a meat slicer. [Background technology]

[0002] Conventionally, there is known a meat slicer that cuts off the tip of a block of meat with a round blade to obtain slices by repeating an action of moving a meat box that holds a block of meat back and forth along the rotation surface of a rotating round blade, and an action of receiving the block of meat with a contact plate attached to the round blade and feeding it out from the meat box in a predetermined amount at a time (see, for example, Patent Document 1). This type of meat slicer is equipped with a thickness adjustment device that supports the contact plate so that it can move in the direction of the rotation axis of the round blade. The thickness of the slices is adjusted by rotating a handle provided on the thickness adjustment device to move the contact plate back and forth relative to the round blade, thereby adjusting the amount of gap between the round blade and the contact plate.

[0003] In conventional meat slicers, a maintenance window is provided on the top surface of the device for use when performing maintenance on the gears and shafts provided inside the thickness adjustment device and when cleaning the inside. The maintenance window is covered with a window cover that is fixed to the top surface of the device with screws. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Jpn. Jpn. Published No. 60-1998 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in conventional meat slicers, when removing and installing the window cover that covers the maintenance window on the top surface of the thickness adjustment device, the support plate and meat box located above the thickness adjustment device hinder the tightening and loosening operation of the screw for fixing the window cover, so there was room for improvement in operability. [Means for solving the problem]

[0006] SUMMARY OF THE PRESENT ART The technical object of the present invention is to provide a meat slicer which has been improved based on the above-mentioned current situation.

[0007] The present invention is a meat slicer comprising a circular blade erected on one of the left and right sides of a machine base, a meat box that moves back and forth along the rotational surface of the circular blade, a contact plate erected on the other left and right side of the machine base along the reciprocating direction of the meat box, and a thickness adjustment device that supports the contact plate so that it can move in the direction of the rotation axis of the circular blade, and obtains sliced ​​pieces from a gap between the circular blade and the contact plate, wherein the thickness adjustment device comprises a box-shaped gear case with an opening at the top, and a case cover that covers the case front side, case rear side, case other side and upper opening of the gear case, and the case cover is fixed to the case other side by a cover fixing screw, and can be removed from the gear case by sliding it in the left and right other side direction by removing the cover fixing screw from the case other side.

[0008] In the meat slicer of the present invention, the cover fixing screw is, for example, a hand screw.

[0009] In addition, the thickness adjustment device may include an axial member inserted through the other side of the case in the left-right direction, a flange member attached to the other side of the case and rotatably supporting the axial member, a handle extending radially of the axial member and rotating integrally with the axial member, and a handle case connecting the axial member and the handle, and the other side of the cover of the case cover may include a cover opening having a larger diameter than the flange member and surrounding the flange member, and a cover slit portion that is wider than the axial diameter of the handle and narrower than the cover opening, and opens to the cover opening and the lower edge portion of the other side of the cover.

[0010] Furthermore, the handle may be configured to be displaceable between a fixed position in which both end portions are located on the outer periphery of the cover opening, and a retracted position in which one of the both end portions is slid so as to overlap with the cover opening, when viewed from the left or right side.

[0011] The gear case may have an inner wall at the bottom of the case that is inclined so as to be high at the front and low at the rear, and a case outlet opening that communicates between the inside and outside of the case is formed at the rear side of the case. Effect of the Invention

[0012] According to the present invention, by removing the screws that secure the case cover of the thickness adjustment device to the other side of the gear case, the case cover can be slid to the left or right and removed from the gear case, thereby improving the ease of attaching and removing the case cover.

[0014] An embodiment of the present invention will be described below with reference to the drawings. A meat slicer 100 (hereinafter simply referred to as "slicer 100") will be outlined with reference to Figs. 1 to 7. In the following description, terms indicating specific directions or positions (such as "front", "back", "front and back", "left and right", etc.) are used, but these are based on the orientation of the operator using slicer 100. In the following description, the position where the operator stands is defined as the front side (near side). These terms are used for convenience of description and do not limit the technical scope of the present invention.

[0015] As shown in Figs. 1 to 7, the meat slicer 100 of this embodiment includes a round blade 1 erected on the left side of the upper surface of a machine base 3, a meat box 2 that moves back and forth along the rotation plane of the round blade 1, and a contact plate 5 erected on the right side of the machine base 3 along the reciprocating direction of the meat box 2. The slicer 100 continuously cuts off the tip of the meat block with the round blade 1 by reciprocating the meat box 2 toward the round blade 1 while restricting the amount of meat block held in the meat box 2 to be sent out by the contact plate 5, and obtains slices from the gap between the cutting edge of the round blade 1 and the contact plate 5. The slicer 100 is of a type in which the round blade 1 is inclined with respect to the vertical direction. The meat box 2 and the contact plate 5 are inclined with respect to the vertical direction, similar to the round blade 1. The slicer 100 includes a thickness adjustment device 6 that supports the contact plate 5 so as to be movable in the axial direction of the rotation shaft 1a of the round blade 1.

[0016] The circular blade 1 is supported on the machine base 3 so as to be rotatable about a circular blade rotation shaft 1a that extends in the front-rear direction while being inclined with respect to the vertical direction, and is driven to rotate by driving an electric motor 11 for driving the circular blade. The meat box 2 includes a bottom plate 21 and a side plate 22, and is supported by a linear shaft 42 fixed to the machine base 3 so as to be reciprocatable in a direction parallel to the rotation plane of the circular blade 1.

[0017] The meat box 2 reciprocates almost horizontally in a direction parallel to the cutting surface of the circular blade 1 (left-right direction) by a crank mechanism 4 driven by the rotation of the output shaft of a reduction gear 41b using an electric motor 41a for driving the meat box as a drive source. A contact plate 5 is erected in front of the stopping position (see FIG. 1, etc.) of the meat box 2. The contact plate 5 is for regulating the position of the tip of the meat block sent out from the meat box 2, and is erected on the right side of the circular blade 1, extending in the left-right direction with an inclined posture with the front high and the rear low.

[0018] The contact plate 5 is supported by a thickness adjustment device 6 provided on the right side of the back of the top surface 31 of the machine base 3 so that its position can be adjusted relative to the circular blade 1 and the meat box 2. The thickness adjustment device 6 is provided so that the front-rear position of the contact plate 5 relative to the rotation plane of the circular blade 1 and the meat box 2 can be adjusted by operating a handle 66.

[0019] 8 to 11, the thickness adjusting device 6 includes a box-shaped gear case 61 with an open top, and a case cover 62 that covers a case front side part 611, a case rear side part 612, a case right side part 613, and the top opening of the gear case 61. The case cover 62 has a cover right side part 623 that covers the case right side part 613 and is detachably fixed to the case right side part 613 by two cover fixing screws 63. The case cover 62 does not cover the case left side part 614 of the gear case 61, and is provided so as to be removable from the gear case 61 by sliding it rightward by removing the cover fixing screws 63 from the case right side part 613.

[0020] In the slicer 100 of this embodiment, by removing the cover fixing screw 63 that fixes the case cover 62 of the thickness adjusting device 6 to the case right side portion 613 of the gear case 61, the case cover 62 can be slid rightward and removed from the gear case 61. When the cover fixing screw 63 is tightened or loosened from the right side of the thickness adjusting device 6, the contact plate 5 and meat box 2 arranged above the thickness adjusting device 6 do not hinder the tightening or loosening of the cover fixing screw 63, improving the ease of attaching and removing the case cover 62.

[0021] In this embodiment, the cover fixing screw 63 is configured as a hand screw. This allows the cover fixing screw 63 to be tightened or loosened without using a screwdriver tool, further improving the ease of attaching and removing the case cover 62. The cover fixing screw 63 may be tightened or loosened with a screwdriver tool. Furthermore, the number of cover fixing screws 63 that fix the case cover 62 to the gear case 61 may be one or three or more.

[0022] The configuration of the thickness adjusting device 6 will be described with reference to Fig. 8 to Fig. 13. The thickness adjusting device 6 includes a moving mechanism 60 that moves a contact plate arm 51, to which a lower part of a contact plate 5 housed in a gear case 61 is fixed by a bolt, back and forth. The moving mechanism 60 is housed in the gear case 61.

[0023] The metal gear case 61 has a box-like shape with an open top, and includes a case front side 611 and a case rear side 612 that extend in the left-right direction in a vertical position with a space between them, a case right side 613 and a case left side 614 that extend in the front-back direction in a vertical position with a space between them, and a case bottom 615 that closes the case bottom. The upper part of the case rear side 612 is inclined forward. The rear part of the case right side 613 is inclined leftward. The case front side 611 is set lower than the case rear side 612, and the upper opening surface of the gear case 61 is approximately parallel to the circular blade rotation shaft 1a.

[0024] The contact plate arm 51 extends in the left-right direction, with its right half disposed inside the gear case 61 and its left half disposed on the left side of the gear case 61. An upwardly opening cutout window 614a is formed in the case left side section 614 to accommodate the middle section of the contact plate arm 51. A guide plate 69 is fixed with screws to the outer wall surface of the case left side section 614. The guide plate 69 slidably holds a cover plate 68 which is movable together with the contact plate arm 51 while closing the cutout window 614a.

[0025] The movement mechanism 60 includes a shaft member 64 connected to a handle 66, a feed screw shaft 602 that rotates following the rotation of the shaft member 64 via a screw gear mechanism 601, a nut member 603 that advances and retreats back and forth on the feed screw shaft 602 as the feed screw shaft 602 rotates, and a sliding shaft 604 fixed to the middle of the contact plate arm 51. The shaft member 64 extends in the left-right direction of a case right side part 613 of the gear case 61, and is rotatably supported by the case right side part 613 and the case left side part 614 with its right end part protruding from the case right side part 613.

[0026] Both ends of the feed screw shaft 602 are rotatably supported by the case front side 611 and the case rear side 612. Both ends of the sliding shaft 604 are slidably supported by the case front side 611 and the case rear side 612. The feed screw shaft 602 and the sliding shaft 604 are arranged parallel to each other and slightly inclined with respect to the circular blade rotation shaft 1a. Note that the feed screw shaft 602 and the sliding shaft 604 may be arranged parallel to the circular blade rotation shaft 1a.

[0027] The feed screw shaft 602 is inserted through a through hole provided in the right end of the contact plate arm 51, and a nut member 603 screwed onto the feed screw shaft 602 is fixed to the contact plate arm 51. A midsection of the sliding shaft 604 is fixed to a midsection of the contact plate arm 51.

[0028] The thickness adjusting device 6 includes an axis member 64 inserted through the case right side portion 613 in the left-right direction, a flange member 65 attached to the case right side portion 613 and rotatably supporting the axis member 64, a handle 66 extending in the radial direction of the axis member 64 and rotating integrally with the axis member 64, and a handle case 67 connecting the axis member 64 and the handle 66. When the axis member 64 is rotated by operating the handle 66 attached to the axis member 64 via the handle case 67 on the right outside of the gear case 61, the rotational force is transmitted to the feed screw shaft 602 via the screw gear mechanism 601. When the screw shaft 602 rotates, the nut member 603 advances and retreats on the feed screw shaft 602. Accordingly, the contact plate arm 51 and the contact plate 5 advance and retreat back and forth, so that the size of the gap between the contact plate 5 and the cutting edge of the circular blade 1 can be adjusted.

[0029] A flange member 65 that rotatably supports the shaft member 64 is fixed to the case right side part 613. A handle case 67 that connects a handle 66 to the shaft member 64 is fixed to the tip of the shaft member 64. The handle case 67 has a large diameter part 671 that is substantially truncated cone shape and covers the shaft member 64 and the flange member 65, and a small diameter part 672 that is connected to the tip of the large diameter part 671.

[0030] 12, the handle case 67 has a large diameter cylindrical hole that houses the flange member 65, and a small diameter cylindrical hole into which the tip of the shaft member 64 is inserted. The shaft member 64 inserted into the small diameter cylindrical hole of the flange member 65 is fixed with a set screw 67a, so that the handle case 67 is fixed to the shaft member 64 so as not to rotate relative to it.

[0031] A handle shaft insertion hole 673 is drilled in a small diameter portion 672 of the handle case 67, perpendicular to the axial direction. The handle 66 is held in the handle case 67 so that handle ends 662 provided at both ends of a handle shaft 661 made of a round metal bar inserted into the handle shaft insertion hole 673 are made larger in diameter than the handle shaft insertion hole 673. A handle fixing screw 663 is screwed into a handle screw hole 661a drilled in the middle of the handle shaft 661. The handle fixing screw 663 is, for example, a hand screw.

[0032] A retaining recess 674 into which the head of the handle fixing screw 663 is fitted, and a shaft insertion groove 675 into which the shaft of the handle fixing screw 663 attached to the handle shaft 661 is inserted are formed on the tip surface of the small diameter portion 672 of the handle case 67. As shown in Figures 8 and 12(A), when the handle fixing screw 663 is fitted into the retaining recess 674, movement of the handle 66 in the axial direction of the handle shaft 661 is restricted.

[0033] As shown in Figs. 8 to 11, the case front side 611, the case rear side 612, the case right side 613 and the upper opening of the gear case 61 are covered with the case cover 62. The case cover 62 is made of sheet metal and has a cover front side 621, a cover rear side 622, a cover right side 623 and a case top surface 624 that cover the sides 611, 612, 613 and the case top opening of the gear case 61. The left side and bottom of the case cover 62 are open. A scale member 70 is fixed to a lower part of the right edge of the case top surface 624. The scale member 70 has a scale marking disposed below and adjacent to the lower right corner of the contact plate 5. By aligning the left side of the contact plate 5 with the scale marking of the scale member 70, the position of the back side surface of the contact plate 5 (the side surface on the meat box 2 side) relative to the rotation surface of the circular blade 1, i.e., the amount of the gap corresponding to the thickness of the sliced ​​pieces to be cut out, can be recognized.

[0034] The cover right side part 623 has a cover opening 623a that has a larger diameter than the flange member 65 and surrounds the periphery of the flange member 65. In this embodiment, the cover opening 623a is formed slightly larger than the outer diameter of the large diameter part 671 of the handle case 67. The cover right side part 623 has the cover opening 623a and a cover slit part 623b that opens at a lower edge part 623c of the cover right side part 623. The cover slit part 623b is provided to be wider than the shaft diameter of the handle shaft 661 of the handle case 67 and narrower than the cover opening 623a.

[0035] When the case cover 62 is attached to the gear case 61, the cover opening 623a surrounds the large diameter portion 671 of the handle case 67, preventing the cover right side portion 623 from coming off upward even when the case cover 62 is not fixed by the cover fixing screw 63. This improves safety.

[0036] As shown in Figs. 9 and 13, two cover fixing screws 63 for fixing the case cover 62 to the gear case 61 are screwed into fixing screw holes 613a formed in the front lower corner and the rear upper corner of the case right side part 613. The cover fixing screw 63 has a threaded part 63b with a larger diameter than the threaded shaft insertion hole 623d at the tip of the shaft part 63a that is inserted into the threaded shaft insertion hole 623d of the cover right side part 623, and is held in the cover right side part 623 so as not to come off. The fixing screw hole 613a has a large diameter opening that does not engage with the threaded part 63b when the cover fixing screw 63 is loosened. The cover fixing screw 63 may be removable from the case cover 62.

[0037] When removing the case cover 62 from the gear case 61, as shown in FIG. 13(B), the two cover fixing screws 63 are loosened so that they are not engaged with the fixing screw holes 613a, that is, the case cover 62 is in a state where it can be removed from the gear case 61. Also, as shown in FIG. 12(B), the handle fixing screw 663 is loosened until it passes the step of the holding recess 674. As shown in FIG. 12(C), the handle 66 is slid along the axial direction of the handle shaft 661 so that the shaft portion of the handle fixing screw 663 is positioned outside the handle case 67 through the shaft insertion groove 675. As a result, the handle 66 is placed in a retracted position where one handle end portion 662 overlaps with the cover opening 623a when viewed from the right. It is not important whether the operation of loosening the cover fixing screws 63 or the operation of placing the handle 66 in the retracted position is performed first.

[0038] 11(A) and 12(D), after aligning the handle shaft 661 with the cover slit portion 623b, the case cover 62 is slid to the right and removed from the gear case 61. Although the meat box 2 is not shown in FIG. 11(A), the case cover 62 can be easily removed even when the meat box 2 is positioned on the thickness adjusting device 6.

[0039] In this way, the case cover 62 can be pulled out to the right from the gear case 61 without removing the handle 66 from the handle case 67, which prevents the handle 66 from falling off or being lost and improves workability. Also, since the case cover 62 can be removed with a simple operation, cleaning workability for removing meat juices and meat scraps accumulated between the gear case 61 and the case cover 62 after removing the case cover 62 is improved and hygienic maintenance can be performed with good workability.

[0040] Also, the handle 66 is provided so as to be displaceable between a fixed position where both handle ends 662 are located on the outer periphery side of the cover opening 623a, and a retracted position where one handle end 662 is slid to overlap the cover opening 623a, as viewed from the right side. As a result, when using the slicer 100, the handle 66 is at the fixed position and the handle shaft 661 is extended in two directions relative to the shaft member 64, improving the operability of the handle 66. On the other hand, when attaching or detaching the case cover 62 to or from the gear case 61, the handle 66 can be at the retracted position and the case cover 62 can be pulled out to the right from the gear case 61 without removing the handle 66 from the handle case 67, improving operability.

[0041] The handle 66 may be of a cantilever type. If the handle is of a cantilever type, the case cover 62 can be attached to and detached from the gear case 61 without moving the handle to the retracted position. The handle 66 may be of a knob type. In this case, by providing the cover opening 623a with a larger diameter than a knob-type handle, the case cover 62 can be slid left and right to be attached to and detached from the gear case 61, and the cover slit portion 623b is not necessary.

[0042] Incidentally, wash water, meat juice, meat scraps, etc. may get into the inside of the gear case 61 through the notched window 614a through which the contact plate arm 51 passes, or through the gap between the case cover 62. Therefore, it is necessary to clean the inside of the gear case 61, but with the conventional technology, it is difficult to remove foreign objects from inside the box-shaped gear case, and there is a problem that cleaning workability is poor.

[0043] The slicer 100 of this embodiment improves the cleaning workability of the inside of the gear case 61 of the thickness adjusting device 6. As shown in Fig. 10, the inner wall of the case bottom 615 of the gear case 61 is inclined in a front-high, rear-low posture with the front side being higher and the back side being lower. Also, a case discharge port 612a that communicates the inside and outside of the case is formed in the case rear side 612. This allows water such as washing water and meat juice that has entered the gear case 61, and foreign matter such as meat chips, to be discharged from the case discharge port 612a, and sanitary maintenance of the thickness adjusting device 6 can be performed with good workability.

[0044] 9 to 11, the cover rear side 622 of the case cover 62 has a discharge cutout 622a that opens to the lower edge at a position corresponding to the case discharge port 612a. This allows moisture and the like that has entered the gear case 61 to be discharged to the outside of the gear case 61 through the case discharge port 612a and the discharge cutout 622a when the case cover 62 is attached to the gear case 61.

[0045] 10 and 11(B), the shaft cover 421 with a downward opening that covers the linear motion shaft 42 at the rear of the thickness adjusting device 6 has a discharge opening 421a at a position facing the case discharge port 612a. Water and meat scraps discharged rearward from the case discharge port 612a flow into the lower part of the shaft cover 421 through the discharge opening 421a and fall downward along the rearward downward inclined piece 31a provided on the top surface 31 of the machine base 3. The water and meat scraps that fall from the inclined piece 31a fall along the inward inclined surface 35a provided on the rear side surface 35 of the machine base 3 and are discharged to the outside of the machine base 3.

[0046] Next, the meat box 2 will be described with reference to Figures 1 to 7, 10, and 14 to 16. The meat box 2 includes a bottom plate 21 on which the lump meat is placed, and a side plate 22 erected on the right edge of the bottom plate 21. The bottom plate 21 is inclined in a low-front-high-rear position, so that the placed lump meat slides down toward the circular blade 1 and the contact plate 5 by its own weight. The bottom plate 21 is supported by a meat box arm 23 that is substantially L-shaped in a side view. The meat box 2 includes an upper pressing mechanism 27 having an upper pressing plate for pressing the lump meat placed on the bottom plate 21 from above, and a lateral pressing mechanism 28 having a lateral pressing tool for pressing the lump meat from the left side toward the side plate 22.

[0047] 10 and other figures, a slider member 23a provided in the vertical midpoint of the meat box arm 23 is slidably supported by a linear motion shaft 42 supported at a portion near the rear edge of the top surface portion 31. A pair of front and rear roller members 23b is provided at the lower portion of the meat box arm 23 located within the machine base 3. The meat box arm 23 is prevented from rotating around the linear motion shaft 42 by sandwiching a rail member 43 extending in the left-right direction within the machine base 3 between the pair of roller members 23b. The rail member 43 is disposed forward of the linear motion shaft 42 when viewed from the side.

[0048] One end of a connecting rod 45 of the crank mechanism 4 is rotatably connected to the lower part of the meat box arm 23. The other end of the connecting rod 45 is rotatably connected to the tip of a crank arm 44 which is connected to the output shaft of the reduction gear 41b inside the machine base 3 and rotates horizontally. When the output shaft of the reduction gear 41b and the crank arm 44 of the crank mechanism 4 are rotated by the drive of the electric motor 41a for driving the meat boxes, the meat box 2 slides back and forth in the left and right direction along the linear motion shaft 42 and the rail member 43.

[0049] 1 to 7, meat box 2 is equipped with weight 24 that presses the rear end of a block of meat (not shown). Weight 24 is equipped with slider portion 241 slidably attached to weight guide shaft 25 disposed on the upper portion of side plate 22, and pressing portion 242 connected to slider portion 241 and abutting against the rear end of the block of meat. A weight lever 243 is connected to slider portion 241.

[0050] In the prior art, when placing a block of meat in the meat box 2, the worker moves the weight 24 along the weight guide shaft 25 toward the upper end until it is removed from the bottom plate 21, and then rotates the weight 24 around the weight guide shaft 25 to hold it at the upper end of the side plate 22. When the worker brings the weight 24 into contact with the rear end of the block of meat placed in the meat box 2, the worker rotates the weight 24 held at the upper end of the side plate 22 and moves it along the weight guide shaft 25 to a position where it comes into contact with the rear end of the block of meat. Thus, when setting a block of meat in the meat box 2, it is necessary to move the weight 24, which is a heavy object, to the upper end of the meat box 2, which requires a great deal of effort from the worker.

[0051] In order to reduce such burden on the worker, the meat box 2 of the slicer 100 of this embodiment is equipped with a weight locking mechanism 26 on the left and right outer sides of the side plate 22 that locks the weight 24 at a midpoint on the weight guide shaft 25.

[0052] 14 to 16, the weight locking mechanism 26 includes a rotating shaft 261 protruding rightward from the right side surface of the side plate 22, a locking lever 262 swingably attached to the rotating shaft 261, a locking pin 263 protruding rightward from the locking lever 262, and an engaging member 264 provided on the slider portion 241 of the weight 24 and having an engaging portion 264a that engages with the locking pin 263. The engaging portion 264a of the engaging member 264 is formed as a recess that opens diagonally downward and forward.

[0053] The pivot shaft 261 is formed, for example, by a bolt screwed into the right side surface of the side plate 22. The locking lever 262 moves the locking pin 263 around the pivot shaft 261 between an engagement position where the locking pin 263 can engage with an engagement portion 264a of the weight 24 and a retracted position where the locking lever 262 is retracted downward from the engagement position. The locking lever 262 has a base end portion rotatably attached to the pivot shaft 261, and has a generally L-shaped form having a pin holding portion 262a to the tip of which the locking pin 263 is fixed, and a weight portion 262b hanging down from the base end portion of the pin holding portion 262a.

[0054] The weight of the weight portion 262b causes the locking lever 262 to assume a position in which the weight portion 262b is located below the rotation shaft 261. The forward rotation of the weight portion 262b is restricted by a rotation restricting member 265 that protrudes from the right side surface portion of the side plate 22 in front of the weight portion 262b. With the weight portion 262b in contact with the rotation restricting member 265, the locking lever 262 is automatically held in a position in which the locking pin 263 is located at the engagement position.

[0055] The weight locking mechanism 26 also includes a lever fixing part 266 that holds the locking lever 262 in the retracted position (see solid line in FIG. 14). The lever fixing part 266 includes a fixing bolt 266a screwed into the side plate 22 diagonally below and behind the rotating shaft 261, and a hand nut 266b screwed into the fixing bolt 266a. Meanwhile, the locking lever 262 includes a locking slit 262c that opens into the rear edge of the weight part 262b. The locking lever 262 can be fixed in the retracted position by rotating the weight part 262b backward around the rotating shaft 261 to position the shaft part of the fixing bolt 266a in the locking slit 262c and then tightening the hand nut 266b. When the locking lever 262 is in the retracted position, the locking pin 263 is disposed in a retracted position where it cannot engage with the engagement part 264a of the weight 24.

[0056] The operation of the weight locking mechanism 26 will be described with reference to Fig. 16. As shown in Fig. 16(A), when the hand nut 266b of the lever fixing part 266 is loosened, the locking lever 262 automatically rotates clockwise as viewed from the right direction due to the weight of the weight part 262b, and the weight part 262b abuts against the rotation restricting member 265, and the locking pin 263 is placed in the engagement position.

[0057] 16(B), when the weight 24, which is positioned forward of the weight locking mechanism 26, is moved upward along the weight guide shaft 25, the locking pin 263 comes into contact with the inclined portion 264b, which is in a front-low, rear-high position and is provided on the lower edge of the engaging member 264 at the rear of the engaging portion 264a. When the weight 24 is further moved upward, the locking pin 263 is pushed down along the inclined portion 264b against the weight of the weight portion 262b, and the locking lever 262 rotates counterclockwise.

[0058] As shown in Fig. 16(C), when the weight 24 is further moved upward and the locking pin 263 passes the inclined portion 264b and the engaging portion 264a, the locking lever 262 automatically rotates clockwise by the weight of the weight portion 262b, and the locking pin 263 is disposed at the engaging position. As shown in Fig. 16(D), when the operating force pushing up the weight 24 is released and the weight 24 is moved downward, the locking pin 263 engages with the engaging portion 264a of the weight 24, and the downward movement of the weight 24 is restricted.

[0059] In this way, the weight 24 can be locked at the middle of the weight guide shaft 25 without being pushed up to the top end of the meat box 2, thereby reducing the burden on the worker when loading the chunk of meat into the meat box 2. Furthermore, the weight locking mechanism 26 can lock the weight 24 by a simple operation of moving the weight 24 upward until the engaging portion 264a exceeds the locking pin 263, and then returning the weight 24 downward, which provides good operability and further reduces the burden on the worker. Furthermore, the weight locking mechanism 26 can be formed with a simple configuration attached to the side plate 22 of the meat box 2, so that a weight locking mechanism 26 that has few breakdowns and is easy to maintain can be formed while suppressing a significant increase in manufacturing costs.

[0060] When releasing the locking of weight 24 by weight locking mechanism 26, as shown in Fig. 16(E), weight 24 is moved slightly upward and locking lever 262 is rotated clockwise. Then, as shown in Fig. 16(F), with locking pin 263 retracted from the engagement position, weight 24 is moved downward and pressing portion 242 of weight 24 is brought into contact with the rear end of the green meat.

[0061] Furthermore, when engaging portion 264a of weight 24 is located above locking pin 263 at the locking position while in contact with the rear end of the green meat placed in meat box 2, locking lever 262 is fixed to lever fixing portion 266 and kept in a retracted position. This makes it possible to prevent a problem in which weight 24 is locked by weight locking mechanism 26 during slicing of the green meat. Note that the shape formed by pin holding portion 262a and weight portion 262b of locking lever 262 is not limited to a substantially L-shape, and may be, for example, a straight or curved shape.

[0062] The upper pressing mechanism 27 and the side pressing mechanism 28 will be described with reference to Figures 17 to 19. The meat box 2 is equipped with the upper pressing mechanism 27 having an upper pressing plate 271 for pressing the chunk of meat placed on the bottom plate 21 from above, and the side pressing mechanism 28 having a side pressing tool 281 for pressing the chunk of meat from the left side toward the side plate 22. The upper pressing mechanism 27 and the side pressing mechanism 28 are supported by a mechanism base member 29 fixed to a left edge of the bottom plate 21 at a midway point in the front-to-rear direction.

[0063] The lateral holding mechanism 28 includes a pair of upper and lower lateral holding jigs 281. The lateral holding jig 281 has a lateral holding rod 281a extending in the front-rear direction in a parallel posture with respect to the bottom plate 21, and a lateral holding handle 281b extending leftward from the front-rear middle part of the lateral holding rod 281a, and has a substantially T-shaped form in a plan view. The lateral holding mechanism 28 holds the lateral holding handle 281b so that it can slide left and right, and is configured so that the lateral holding jig 281 can be switched between a fixed state and a movable state by operating a lateral holding lever 282.

[0064] The upper presser plate 271 of the upper presser mechanism 27 is made of, for example, stainless steel, and includes a main surface portion 271a that is generally rectangular in plan view and disposed parallel to the bottom plate 21, and a narrow base portion 271b that extends leftward from a rear portion of the left edge of the main surface portion 271a. Reinforcing ribs 271c are provided upward on the periphery of the main surface portion 271a and the base portion 271b. The reinforcing ribs 271c are not provided on the front edge portion of the main surface portion 271a or the tip portion of the base portion 271b, so that moisture and meat scraps are less likely to remain on the upper presser plate 271.

[0065] A plate support shaft 272 made of a round bar is fixed to the underside of the tip end of the base 271b of the upper presser plate 271. The upper presser mechanism 27 includes a shaft holding mechanism 273 that holds the plate support shaft 272 rotatably and vertically movable. The shaft holding mechanism 273 includes a shaft support base portion 274 fixed to the rear portion of the mechanism base member 29, and an upper shaft support portion 275 and a lower shaft support portion 276 that extend rearward from the upper and lower ends of the shaft support base portion 274. The lower shaft support portion 276 has an insertion hole that rotatably holds the lower half of the plate support shaft 272 in an upright position, facing in the vertical direction.

[0066] The upper shaft support portion 275 is formed of, for example, a shaft holder, and has a slit connected to a vertical insertion hole 275a (see FIG. 19) that holds a portion near the upper end of the plate support shaft 272 and opens at its end face. The width of the slit can be changed by changing the degree to which the screw member 277b is screwed in, so that the inner diameter of the insertion hole can be changed. The upper shaft support portion 275 is provided so that the inner diameter of the insertion hole can be adjusted between a size smaller than the outer diameter of the plate support shaft 272 and a size larger than the outer diameter of the plate support shaft 272 by rotating the screw member 277b that extends in the left-right direction around its axis. A screw portion provided at the right end of the screw member 277b is screwed into the rear end of the upper shaft support portion 275 from the left side. A presser plate fixing lever 277a is fixed to the right end of the screw member 277b.

[0067] The inner diameter of the upper shaft support part 275 can be adjusted by rotating the presser plate fixing lever 277a and rotating the screw member 277b about its axis. This allows the plate support shaft 272 inserted into the upper and lower shaft support parts 275, 276 to be switched between a state in which it can slide up and down and rotate about the plate support shaft 272, and a locked state in which it cannot move or rotate.

[0068] A first restricting portion 278 restricting the forward rotation range of the upper presser plate 271 and a second restricting portion 279 restricting the backward rotation range of the upper presser plate 271 are protrudingly provided on the plate support shaft 272 at a position between the upper and lower shaft support portions 275, 276. The restricting portions 278, 279 are formed by, for example, bolts screwed into the peripheral wall of the plate support shaft 272. The downward movement range of the upper presser plate 271 is restricted by the contact of a base portion 271b of the upper presser plate 271 with the upper shaft support portion 275. The upward movement range of the upper presser plate 271 is restricted by the contact of the first restricting portion 278 with the upper shaft support portion 275. In this way, the shaft holding mechanism 273 holds the plate support shaft 272 so that it cannot come off.

[0069] 17(B), when the first restricting portion 278 comes into contact with the shaft support base portion 274, the forward rotation of the upper presser plate 271 is restricted and the upper presser plate 271 stops above the bottom plate 21. On the other hand, when the second restricting portion 279 comes into contact with the shaft support base portion 274, the rearward rotation of the upper presser plate 271 is restricted and the upper presser plate 271 stops at a retracted position that is off to the rear left side from above the bottom plate 21. In the retracted position, the upper presser plate 271 is inclined with a front-low and rear-high posture, and the center of gravity of the upper presser plate 271 is configured to be located to the left of the plate support shaft 272, so that the upper presser plate 271 is held in the retracted position even if the operator releases it.

[0070] Thus, slicer 100 comprises circular blade 1 which is erected on one side of machine base 3 and rotates, and meat box 2 which moves back and forth along the rotation plane of circular blade 1, and obtains sliced ​​pieces by cutting off a block of meat delivered from meat box 2 with rotating circular blade 1. Meat box 2 comprises bottom plate 21 on which the block of meat is placed, and upper presser mechanism 27 having upper presser plate 271 which restricts the upward movement of the block of meat placed on bottom plate 21. Upper presser mechanism 27 comprises shaft support part 275 which can adjust the inner diameter of insertion hole 275a which holds plate support shaft 272 hanging down from upper presser plate 271 by tightening or loosening screw member 277b. The upper pressure mechanism 27 is configured to be switchable between a fixed state in which the insertion hole 275a is narrowed to hold the plate support shaft 272 unable to move up and down and unable to rotate, and a released state in which the insertion hole 275a is widened to hold the plate support shaft 272 able to move up and down and freely rotate, by operating a pressure plate fixing lever 277a secured to a screw member 277b.

[0071] The upper presser mechanism 27 of this embodiment can fix and release the vertical movement and rotation of the upper presser plate 271 and the plate support shaft 272 by operating one presser plate fixing lever 277a, improving workability. In addition, the upper presser mechanism 27 can fix and release the vertical movement and rotation of the plate support shaft 272 by the upper shaft support part 275 consisting of a shaft holder, for example, so that it can be formed with a very simple configuration, and weight and cost can be reduced. The shaft holder constituting the upper shaft support part 275 may be a type having a slit connected to the insertion hole 275a, or a separate type or hinge type in which the insertion hole 275a is formed by two members. In addition, it may be a configuration in which the plate support shaft 272 is held by only the upper shaft support part 275 without providing the lower shaft support part 276. Also, the lower shaft support portion 276 may be configured as a shaft holder, and the upper shaft support portion 275 may be configured to rotatably hold the plate support shaft 272. Furthermore, since the upper pressing plate 271 is formed by bending a stainless steel plate, it is possible to realize a reduction in weight and cost.

[0072] The upper presser mechanism 27 also includes a shaft support base portion 274 that supports the shaft support portion 275, and restriction portions 278, 279 that protrude from the outer circumferential surface of the plate support shaft 272 and restrict the rotatable range of the plate support shaft 272 by moving toward and away from the shaft support base portion 274 as the plate support shaft 272 rotates about its axis. This makes it possible to restrict the rotatable range of the plate support shaft 272 with a simple configuration.

[0073] Furthermore, the first restricting portion 278 is provided on the plate support shaft 272 below the upper shaft support portion 275, and restricts the upward movement range of the plate support shaft 272 by abutting against the upper shaft support portion 275. This makes it possible to prevent the plate support shaft 272 from coming out of the insertion hole 275a with a simple configuration, thereby improving operability and safety.

[0074] Next, the machine base 3 of the slicer 100 will be described with reference to Figs. 1 to 7. The machine base 3 has four legs 32 that support the corners of a top surface 31 that is rectangular in plan view. The legs 32 are formed, for example, of stainless steel square pipes. An adjuster 321 that is placed on the installation surface and is height adjustable is provided at the lower end of the legs 32. The lower ends of the legs 32 that are aligned in the left-right direction are connected to each other by a stainless steel lower frame 33 that extends in the front-rear direction. Casters 331 are fixed to positions near the left and right edges of the lower frame 33.

[0075] The four legs 32 are provided in a substantially vertical position when viewed from the side in the extension direction of the reciprocating movement direction of the meat box 2, while being inclined such that the lower ends of the legs 32 are positioned outward relative to the upper ends when viewed from the front or rear in a direction perpendicular to the reciprocating movement direction. This allows the ground contact area of ​​the machine base 3 to be increased in the left-right direction (the reciprocating movement direction of the meat box 2) without increasing the front-to-rear width, and while preventing a significant increase in installation space, the configuration ensures ease of installation work in installation locations with narrow openings, while reducing vibration during the slicing operation of the slicer 100.

[0076] The top surface 31 is formed in a generally rectangular shape that is long in the left-right direction, and covers the upper ends of the legs 32. The machine base 3 has a front side surface portion 34, a rear side surface portion 35, a right side surface portion 36, and a left side surface portion 37 that close the sides of the space surrounded by the four legs 32. The bottom of the space surrounded by the four legs 32 is closed by a machine base bottom plate 38. The top surface 31, the side surfaces 34, 35, 36, 37, and the machine base bottom plate 38 are formed of stainless steel plates.

[0077] The machine base 3 contains an electric motor 41a for driving the meat box that drives the crank mechanism 4, an electric motor 11 for driving the circular blade that rotates the circular blade 1, and a control device (not shown) for controlling the driving of the electric motors 11 and 41a. Although not shown, the control device is disposed near the right side portion 36.

[0078] The electric motor 41a for driving the meat box is disposed at a position near the center of the lower part of the machine base 3 with the motor shaft facing forward. The driving force of the electric motor 41a is transmitted to the reducer 41b disposed above the electric motor 41a. The base end of the crank arm 44 of the crank mechanism 4 is connected to the output shaft of the reducer 41b disposed upward. As described above, one end of the connecting rod 45 is rotatably connected to the tip of the crank arm 44 that rotates horizontally in the machine base 3, and the other end of the connecting rod 45 is rotatably connected to the lower part of the meat box arm 23 of the meat box 2. When the output shaft of the reducer 41b and the crank arm 44 rotate due to the drive of the electric motor 41a, the meat box 2 reciprocates and slides along the linear shaft 42 and the rail member 43 in the left and right direction.

[0079] The electric motor 11 for driving the circular blade is disposed near the left side surface 37 within the machine base 3 with the motor shaft facing diagonally upward and backward so that it is parallel to the circular blade rotation shaft 1a. The driving force of the electric motor 11 is transmitted to the circular blade rotation shaft 1a via a power transmission mechanism 13 provided within a blade support case 12 erected at the front left corner of the top surface 31.

[0080] As shown in Figs. 1 to 7, the circular blade 1 is held in an inclined position above the front left part of the top surface 31 of the machine base 3. The circular blade 1 is supported rotatably with its rotation surface inclined by a blade support case 12 erected at the front left corner of the top surface 31. The blade support case 12 constitutes a housing case for a power transmission mechanism 13 that transmits the driving force of an electric motor 11 for driving the circular blade to the circular blade rotation shaft 1a. The electric motor 11 for driving the circular blade is disposed in the machine base 3 near the left side surface 37 with the motor shaft facing diagonally upward and backward so as to be parallel to the circular blade rotation shaft 1a. The driving force of the electric motor 11 is transmitted to the circular blade rotation shaft 1a through the power transmission mechanism 13, and the circular blade 1 fixed to the rear end of the circular blade rotation shaft 1a in a relatively non-rotatable manner is driven to rotate.

[0081] When the meat box 2 containing the chunk of meat is moved back and forth while the circular blade 1 is driven to rotate, slices are cut out from the gap between the cutting edge of the circular blade 1 and the contact plate 5. Below the circular blade 1, a resin regulating plate 7 (see Figs. 2 to 4) is disposed in an upright position and is detachably attached to the right rear end of the blade support case 12. The regulating plate 7 prevents the hand of the operator who receives the sliced ​​piece below the circular blade 1 from reaching the back side of the blade support case 12, improving safety.

[0082] Next, the operation tool group 8 for operating the slicer 100 will be described with reference to Figures 20 and 21. As shown in Figures 1 to 3, 6, 7, etc., the operation tool group 8 for operating the slicer 100 is provided on the right side surface 36 of the machine base 3. The operation tool group 8 is arranged near the upper front portion of the right side surface 36, and includes an on / off switch 81 (on switch) and a total stop switch 82 (stop switch). The on / off switch 81 and the total stop switch 82 are momentary push button switches.

[0083] As shown in Figs. 20 and 21, the switches 81 and 82 are attached upward to an upper surface portion 831 of a switch support portion 83 that protrudes rightward from the right side surface portion 36. The switch support portion 83 has a box-like shape that opens into the inside of the machine base 3, and includes an upper surface portion 831 that is inclined left-high and right-low, a right surface portion 832 that hangs down diagonally rightward from the right edge of the upper surface portion 831 parallel to the right side surface portion 36, a front surface portion 833 and a rear surface portion 834 that hang down perpendicularly to the right surface portion 832 from the front and rear edges of the upper surface portion 831, and a bottom surface portion 835 that is connected to the lower edges of the right surface portion 832, the front surface portion 833, and the rear surface portion 834 in a position perpendicular to the right side surface portion 36 of the machine base 3. In this embodiment, the switch support portion 83 is provided integrally with the right side surface portion 36.

[0084] 6, since the switches 81, 82 protrude upward from the upper surface 831 of the switch support part 83, an operator working on the front side of the machine base 3 can easily see the switches 81, 82, improving operability, compared to a configuration in which the switches 81, 82 protrude rightward from the right side surface 36 of the machine base 3. Also, since the upper surface 831 of the switch support part 83 is provided in an inclined position that is lower toward the left and right outer sides (right side), it is possible to prevent moisture and meat scraps from accumulating on the upper surface 831, which is easy to clean and hygienic.

[0085] When the on / off switch 81 is pressed, the control device (not shown) of the slicer 100 supplies driving power to the electric motor 11, 41a to rotate the circular blade 1 and continuously reciprocate the meat box 2. For example, the control device may switch between one reciprocating movement or continuous reciprocating movement of the meat box 2 depending on the number of times the on / off switch 81 is pressed. With this configuration, the operator can reciprocate the meat box 2 to slice with a simple operation of pressing the push-button type on / off switch 81, improving operability. In addition, the meat box 2 is switched between one reciprocating movement or continuous reciprocating movement depending on the number of times the on / off switch 81 is pressed, so the operator can select between single cutting and continuous cutting with a simple operation, improving operability.

[0086] The control device may also rotate the circular blade 1 when the ON / OFF switch 81 is pressed, and may further move the meat box 2 back and forth once or continuously when the ON / OFF switch 81 is pressed once or multiple times. With this configuration, the circular blade 1 is rotated in advance before the meat box 2 starts to move back and forth, thereby preventing deterioration of the cut surface of the sliced ​​pieces due to insufficient rotation speed of the circular blade 1. In addition, since the operation to start the rotation of the circular blade 1 and the operation to start the reciprocating movement of the meat box 2 are performed using the same ON / OFF switch 81, operability and workability are good, and the rotation speed of the circular blade 1 sufficient to neatly cut sliced ​​pieces from the block of meat can be ensured at the time when the meat box 2 starts to move back and forth.

[0087] When the stop switch 82 is pressed, the control device stops the driving of the electric motor 11 and controls the driving of the electric motor 41a so as to stop the meat box 2 at the front end position. In addition, when the on / off switch 81 is pressed while the meat box 2 is moving back and forth, the control device may move the meat box 2 to the stop position and stop it. With this configuration, the one on / off switch 81 can be used to start the single-piece cutting operation or the continuous slicing operation and to stop the continuous slicing operation, improving operability and workability. In addition, even if the on / off switch 81 is pressed by mistake instead of the stop switch 82 to stop the continuous slicing operation, the meat box 2 can be stopped at the stop position, improving safety.

[0088] As shown in Fig. 20 and Fig. 21, a switch cover 84 is rotatably attached to the switch support part 83. The switch cover 84 has a substantially U-shaped form when viewed from the right, and includes a pair of front and rear cover legs 842, 842 rotatably attached to a cover rotation shaft 841 provided on front and rear surfaces 833, 834 of the switch support part 83, and a cover part 843 connected to the free rotation ends of the cover legs 842, 842 to cover the switches 81, 82. The cover part 843 has a substantially L-shaped cross section that covers the upper and right sides of the switches 81, 82 when placed above the switch support part 83. In the closed state in which the cover part 843 covers the switches 81, 82, contact with the switches 81, 82 by a worker, a cart, or other foreign object can be prevented, and unintentional switch operation can be prevented, improving workability and safety.

[0089] The cover legs 842, 842 are rotatably supported by a cover rotation shaft 841 that is inserted into an elongated hole 842a along the longitudinal direction so as not to come off. As shown in FIG. 20(A), when the cover part 843 is in the closed state, the end of the elongated hole 842a on the cover part 843 side is supported by the cover rotation shaft 841. At this time, a cover leg end 842b of the cover leg 842 on the opposite side to the cover part 843 is located below the bottom surface part 835, and its leftward movement is restricted by a rotation prevention member 85 that protrudes outward from the front and rear sides beyond the surfaces 833, 834 and is attached to the bottom surface part 835. This prevents the switch cover 84 from rotating.

[0090] When opening the switch cover 84, as shown in FIG. 20(B), the worker lifts the switch cover 84 so that the cover leg end portion 842b is above the anti-rotation member 85. Then, as shown in FIG. 20(C), the worker rotates the switch cover 84 clockwise when viewed from the front. As shown in FIG. 20(D), when the worker releases the switch cover 84, the switch cover 84 enters an open state in which it hangs from the cover rotation shaft 841. When the switch cover 84 is in the open state, a resin buffer member 86 provided on the right side surface portion 36 of the machine base 3 faces the cover portion 843, preventing damage to the right side surface portion 36 and the switch cover 84. The buffer member 86 does not necessarily have to be provided.

[0091] Next, the components attached to the support case cover 121 of the blade support case 12 will be described with reference to Figures 22 and 23. The box-side blade support case 12 has a maintenance window 12a on the front side. The maintenance window 12a is covered by the support case cover 121 which is detachably attached to the front side of the blade support case 12.

[0092] An emergency stop switch 122 and an indicator lamp 123 that indicates the operating state are attached to the support case cover 121. When the emergency stop switch 122 is pressed, it immediately stops the power supply to the motors 11, 41a, stopping the rotation of the circular blade 1 and the reciprocating movement of the meat box 2. The indicator lamp 123 includes, for example, a power lamp 124 that indicates the power-on state, and a circular blade rotating lamp 125 that indicates the operation of the circular blade 1.

[0093] A switch wiring 122a extending from the emergency stop switch 122 and a lamp wiring 123a extending from the indicator lamp 123 pass through the machine base 3 and are connected to a control device (not shown) installed at a right side location in the machine base 3. A switch wiring connector 126 is interposed in the middle of the switch wiring 122a. The connector 126 connects a first terminal 126a on the emergency stop switch 122 side to a second terminal 126b on the control device side. Similarly, a lamp wiring connector 127 having a first terminal 127a and a second terminal 127b is interposed in the middle of the lamp wiring 123a. The connectors 126 and 127 are disposed near a machine base window 34a provided on the front side surface portion 34 of the machine base 3. The machine base window 34a is covered by a machine base window cover 341 provided on the front side surface portion 34 so as to be freely opened and closed. A group of switches 9 (see FIG. 23) including a power switch, an operation changeover switch, etc. are disposed in the machine base 3 at a position facing the machine base window 34a.

[0094] By separating the terminals 126a, 126b of the connector 126 and also separating the terminals 127a, 127b of the connector 127, the emergency stop switch 122 and the indicator lamp 123 can be removed together with the support case cover 121 from the blade support case 12 and the machine base 3. This improves the ease of removal and installation of the emergency stop switch 122 and the indicator lamp 123.
