Description

  The present invention relates to a meat slicer. More specifically, the present invention relates to a meat slicer in which a sliced meat piece cut out from a meat block is directly carried out by a carry-out conveyor and is transferred from the carry-out conveyor to a storage container such as a tray or a pielesh manually.

  One example of a meat slicer that receives a sliced meat piece cut from a conventional meat block manually is disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2002-239981).

  The meat slicer disclosed in this Patent Document 1 is provided with a meat box that holds a meat block on the right or left side of the rotary blade as viewed from the operator side and can be intermittently sent out from the tip portion, The meat box is reciprocated in a direction substantially parallel to the rotary cutter, and the meat block to be delivered is sliced to a predetermined thickness with the rotary cutter and cut out from the right or left side of the rotary cutter.

  The worker stands in parallel so as to follow the feeding direction of the meat block at the position of the front side portion of the machine base, and receives the sliced meat pieces in a posture in which the front of the body faces the machine side.

  When the meat block is cut by the rotary blade, the meat block is cut diagonally from one corner and cut in such a state that it is rolled in this cutting direction. The sliced meat piece cut out in this way is first gripped by the right or left hand, then received with the left or right hand on the opposite side as necessary, and the sliced meat piece is placed in the container while adjusting the posture of the received sliced meat piece. And repeat the above operations.

  Using the meat slicer disclosed in Patent Document 1 as described above, the work of manually receiving the sliced meat piece to be cut directly from the sharp blade that rotates at high speed is always dangerous and requires careful attention. When cutting a relatively small portion of meat such as pork loin and taking it out without the need for folding or alignment, it is also possible to receive a slice of meat with only one hand. However, when cutting a piece of meat close to ice temperature, which is a relatively large part such as beef's thigh, to a thickness of about 2 to 3 mm, it must be received with both hands. It is difficult and difficult to receive sliced meat pieces that are cut in a diagonal line from one corner and cut in such a state that it is rolled in the cutting direction, arrange the posture, fold it and store it in a container such as a tray In short, there is a problem in the safety of workers working near the slicer.

  Further, in this meat slicer, there is a rotary blade on one side of the slice meat receiving position, and the drive shaft of the rotary blade is extended and supported in front of the machine base. As a result, the place where the sliced meat pieces were received was limited, and the work was cramped.

  In addition, the operator must constantly monitor the operation status of each part, such as the remaining amount of meat blocks loaded in the meat box and how they are fed during work, but the work position on the front side of the machine base as described above From the point of view, the face must be turned one by one, and since the line of sight deviates from the hand that is receiving the sliced meat pieces, there is a problem that the anxiety of the fingertip cut by the blade increases and the body and body are stressed strongly.

  Also, because the meat block or cutter reciprocates left and right, when slicing raw meat, the sliced thin meat sticks to the cutter or is blown off, making it difficult to order the sliced meat pieces in order, and subsequent serving and tray packaging Such processing operations are difficult to perform smoothly.

  The present applicant aims to provide a meat block slicer that solves the above-mentioned problems of the prior art, can improve the safety of workers working in the vicinity of the slicer, and can efficiently slice meat blocks. As a proposal, a meat block slicing apparatus (meat slicer) of Patent Document 2 (Japanese Patent No. 3567236) has been proposed.

The apparatus proposed by this patent document 2 is a delivery device that feeds meat blocks, a cutter that slices the meat blocks sent to the cutter by the delivery device from the upper side to the lower side, and a receipt that receives the cut and separated sliced meat. The cutter and the receiving device are installed at fixed positions, and the feeding device is capable of reciprocating in the vertical direction, and the receiving device holds the cut and separated thin slices. It is a sliced apparatus of a meat block characterized by consisting of a roll or endless belt provided with.
JP 2002-239981 A Japanese Patent No. 3567236

  With the apparatus disclosed in Patent Document 2 described above, the present invention solves the problems associated with the prior art of Patent Document 1 described above, and when the sliced meat pieces to be cut out are manually received, But there will be a meat slicer that can be used safely and easily.

  However, there is no conventional device that extends the receiving device that receives the sliced meat piece that is cut and separated (sliced) by the cutter to the takeout position as it is, and uses the device disclosed in Patent Document 2 to convey the sliced meat piece. If it is going to carry out by (1), a slice meat piece must be transferred from a roll or an endless belt to a carrying-out conveyor, and an apparatus will enlarge and will become complicated.

In view of such problems, the present invention can be used with ease even if it is an unskilled person when receiving sliced meat pieces to be cut out, and without increasing the size and complexity of the apparatus. It aims at providing the operation method of the meat slicer which can supply a slice meat piece with a carrying-out conveyor in an orderly state.

The present invention achieves the above object by supporting the meat block, supported by the machine base so as to reciprocate up and down a predetermined section by the crank mechanism, and supported by the left and right sides of the machine base for feeding the stored meat block. A band knife for slicing the front end of the meat block, and a contact plate for receiving the front end of the meat block. A slicer in which a sliced meat piece cut-out opening is formed between the upper end surface of the plate, and a conveyor constituted by an endless belt continuously and integrally extends between the abutment plate and the sliced meat piece extraction position. In the established meat slicer,
The starting end portion of the conveyor on the side close to the contact plate is positioned close to the upper end surface of the contact plate, and obliquely upward from the upper end surface of the contact plate so as to be along the lower surface of the sliced meat piece cut out from the cutout opening. Forming a receiving surface with a smooth surface at the starting end, consisting of a curved surface projecting outward toward
The conveyor is synchronized with the movement of the sliced meat piece when the sliced meat piece is cut out from the meat block by synchronizing the timing at which the receiving surface of the conveyor moves and the timing at which the sliced meat piece is cut out from the meat block of the meat box. Running,
Until the sliced meat piece is cut from the meat block, the sliced meat piece being cut out from the cutout opening is received in contact with the receiving surface of the curved surface being traveled,
Only within the range excluding the vicinity of the time of receiving the sliced meat piece, the conveyor is stopped or the traveling speed of the conveyor is reduced from the speed at the time of receiving the sliced meat piece,
The sliced meat piece received on the receiving surface is conveyed to the take-out position.
This is achieved by a method for operating a meat slicer .

  In this case, the abutment plate is connected to the receiving device, and is adjusted to move in the feeding direction of the meat block while maintaining at least the relational position between the upper end surface of the corresponding plate and the starting end portion of the receiving device. If possible, even if the plate is moved away from the cutting edge of the band knife in order to adjust the slice thickness, the relative position between the upper end surface of the plate and the starting end of the receiving device does not change, so the sliced meat pieces to be cut out can be surely You can receive it.

  The receiving device is preferably an endless belt with a smooth surface, and in this way, the sliced meat pieces are less likely to be disturbed because they adhere easily, and the familiarity with the scraper is better compared to those with protrusions and cleaning is possible. It is easy and preferable.

  In addition, the meat block is cut horizontally and linearly by the band knife so that it can be received along the receiving surface without any disturbance, and the sliced slice to be cut out is at least a meat block. It is preferable that the sliced meat pieces are arranged so that they can be received in contact with each other before being cut off, so that they can be prevented from being pulled by the blade.

  The receiving surface is formed from the upper end surface of the abutting plate obliquely upward along the lower surface of the sliced meat piece cut out from the cutout opening, and has a smooth curved surface with a high front protruding outward. It becomes easier to follow the sliced meat piece to be cut out, which is preferable.

More specifically, as shown in the drawing, the meat slicer for carrying out the operation method of the present invention reciprocally swings up and down in a certain section near the horizontal position around a fulcrum provided at the rear. A meat box supported by the machine base for feeding out the stored meat block, a band knife for slicing the front end portion of the meat block stored in the meat box, and receiving the front end portion of the meat block in the receiving and feeding direction. A slicer that regulates the thickness of the slice, and a slicer with a cut-out port for the sliced meat formed between the cutting edge of the band knife and the upper end surface of the plate, the start end of which is above the plate An endless band that is positioned close to the end face and has a receiving surface that receives the sliced meat piece obliquely upward from the upper end surface of the abutting plate along the lower surface of the sliced meat piece cut out from the cut-out opening The sliced meat piece is composed of a receiving device that receives the sliced meat piece on the receiving surface while running in synchronization with the movement of the sliced meat piece, and the receiving device is located at a position where the sliced meat piece is placed forward from the starting end. The receiving device receives the sliced meat in contact with the sliced meat piece at least until the sliced meat slice to be cut is separated from the meat block. It is preferable that the meat slicer is arranged so that it can be used and also serves as a carry-out conveyor for carrying the sliced meat pieces to the take-out position.

  Further, the receiving device is a conveyor having a smooth surface, and a pressing tool for pressing the sliced meat piece being cut out above the conveyor toward the receiving surface of the receiving device, the sliced meat piece contact surface of the pressing tool It is preferable that the attachment is performed such that the gap between the surface and the receiving surface is equal to or less than the thickness of the sliced meat piece. The shape of the pressing tool is not particularly limited, but as an example, a large number of thin spring wires may be provided in a comb shape across the width of the conveyor, the gap between the pressing tool and the conveyor can be adjusted, and a plurality of pressing tools can be provided as necessary. It may be mounted, and it is preferable that the pressing tool can easily take the operating position and the retracted position.

  Further, it is preferable to take a safety protection measure by covering the blade edge of the blade with the pressing tool and the receiving surface so that a human fingertip cannot reach the blade edge.

  Regarding the operation timing of the slicer of the meat block according to the present invention, the carry-out conveyor is stopped only within the range except the vicinity of the time when the sliced meat piece is received, or the running speed of the carry-out conveyor is reduced, and the slice on the conveyor The interval between the meat pieces may be adjusted, and the traveling speed of the carry-out conveyor may be adjusted within a range excluding the vicinity of the time when the slice meat pieces are received, so that the sliced meat pieces can be easily taken out from the carry-out conveyor. .

  Further, it is preferable that the stop or deceleration start time of the conveyor can be adjusted and / or the return time from the stop or deceleration state to the high speed can be adjusted. That is, if the conveyor stop or deceleration start time is advanced, or the conveyor stop or deceleration recovery time is delayed, the conveyor speed will be slower than the sliced slices that are cut out relatively, Appropriate sagging (wrinkles) is generated in the sliced meat piece to be taken out, and it becomes easy to remove from the conveyor. Conversely, if the conveyor stop or deceleration start time is delayed, or the conveyor stop or deceleration state is returned to high speed, the conveyor speed will be higher than the speed of the sliced slices that are relatively cut out. The sliced meat pieces taken out on the conveyor are stretched and no sagging occurs. In use, both aspects are used as appropriate.

  In addition, the meat box can be moved up and down by a crank mechanism, and by setting the traveling speed near the time of receiving the sliced meat piece of the receiving device to a constant speed that substantially matches the maximum movement speed of the meat box, Since the conveyor speed is relatively gradually increased, the sliced meat pieces are stretched to prevent wrinkling.

  When the sliced meat pieces to be taken out on the conveyor are picked up one by one with fingertips at the takeout position, it is advantageous that there is a moderate sag. Also, when scooping with a spatula or the like and transferring it directly to a tray or the like, the sliced meat pieces are stretched to improve the appearance.

  The number of reciprocating movements per unit time of the meat box can be adjusted, and the carry-out conveyor may be set to stop or reduce the moving speed only when the number of reciprocating movements per unit time of the meat box is large. . This is usually used at high speeds (about 50 times or more per minute) when cutting pork loin or the like, but it may work at low speeds (about 30 times or less per minute) for large meat such as thighs. This is because, when both the speed and the conveyor speed are slow, the work is relatively easy to perform, so the conveyor speed should be constant without stopping or decelerating.

According to the present invention, there is provided a method for operating a meat slicer that does not cause the slice meat pieces to be transferred from the receiving apparatus to the carry-out conveyor, and that there is no trouble such as disorder, entrainment, or clogging of the slice meat pieces.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings illustrating an embodiment of a meat slicer for carrying out the operation method of the present invention. In the accompanying drawings, FIG. 1 is a side view showing an example of a meat slicer used in the method of the present invention, and FIG. 2 is a plan view. FIG. 3 is an enlarged cross-sectional view of the cutting part as viewed from the side.

  With reference to FIG. 1 and FIG. 2, the structure of the Example which concerns on this invention is demonstrated. A pair of left and right columns 2 and 2 are erected on the rear (left side in FIG. 1) upper portion of the box-shaped machine base 1. Bearings 4 and 4 such as ball bearings are attached to the upper ends of the respective columns 2 and 2. The support shafts 9 and 9 are integrally projected from the left and right side walls of the rear portion of the meat box 3 holding the meat block M, and the support shafts 9 and 9 are fitted to the bearings 4 and 4 so that the meat box 3 is supported by the support shaft 9. , 9 (corresponding to a fulcrum) as a center, a fixed section near the horizontal position is supported so that it can swing back and forth up and down.

  The meat box 3 has a width that can accommodate the meat block M, and is configured in a bowl-like shape with the top opened. Rollers 6 and 6 are laid across the meat box 3, and a conveyor belt 5 is stretched across the entire width of the bottom of the meat box 3 between the rollers 6 and 6. A servo motor (not shown) is connected to the rear roller 6 and is intermittently driven so that the meat block M mounted on the belt can be fed forward.

  A pressing tool 7 is provided above the front portion (right side in FIG. 1) of the meat box 3 so that the vicinity of the front end portion of the meat block M can be pressed from the top toward the bottom. For example, as shown in FIG. 1, the pressing tool 7 is made of a plate material having a “te” -shaped cross section and having a width dimension capable of pressing the front end of the meat block M over the entire width. One end (rear end) of the pressing tool 7 extends rearward and is fixed to the support arm 8 with a mounting screw or the like. The support arm 8 is formed in an arch shape so as to bypass the feeding passage of the meat block M of the meat box 3. The support arm 8 branches left and right and extends rearwardly along the outer sides of the left and right side walls of the meat box 3, and its end is formed in a ring shape, and supports shafts 9, 9 that support the meat box 3. And is rotatably supported. That is, the support arm 8 to which the pressing tool 7 is fixed is supported so as to be swingable in the vertical direction about the support shaft 9, so that an extension device such as an air cylinder (see FIG. (Not shown), the pressing tool 7 is pulled up when the meat block M is sent out, and the pressing tool 7 is strongly pressed against the meat block M when cutting the tip of the meat block M. Adjustment is possible.

  A receiving blade frame 10 having a rectangular frame shape is attached to the front end of the meat box 3 so as to surround the front edge. The front end face of the receiving blade frame 10 has an arc shape centered on the support shaft 9 in a side view shown in FIG. 1, and the lower frame portion and the side pressed by the blade when the meat block M is cut (the end of cutting). The front end surface of either the left or right side frame portion that becomes the right side) becomes a receiving blade surface when the meat block M is cut by the band knife 13 described later.

  A lower part of the meat box 3 configured as described above is appropriately reinforced, and a swing pin 11 is attached. On the other hand, a crank device 12 is provided inside the machine base 1. The crank device 12 has a servo motor 12b for driving connected to a rod 12a, and connects the swing pin 11 and the rod 12a of the crank device 12 so that the meat box 3 has a front end upper surface of the meat block M, and a band knife 13 Starting from a position below the cutting edge, the servo motor 12b reciprocally swings until the lower surface of the meat block M passes through the cutting edge.

  The front edge surface of the receiving blade frame 10 at the position where the swing is started is substantially arc-shaped as the front end surface of the receiving blade frame 10 and has a size that covers the entire opening of the receiving blade frame 10, and the meat to be delivered A contact plate 14 capable of receiving the front end surface of the block M is provided. The abutment plate 14 is supported on the machine base 1 via the link mechanism 15 so that the slice thickness can be regulated by moving substantially in the feeding direction. The link mechanism 15 is connected to a telescopic device 16 using screws provided in the machine base 1.

  An endless band knife 13 is disposed so that the cutting edge is positioned at a distance of approximately the slice thickness dimension from the upper end surface of the plate 14 to constitute a slice meat cut-out port. In the present embodiment, a band-shaped tool steel having a width of 13 mm and a thickness of about 0, 5 mm is used as the band knife 13, and a sharp edge is given to the end face on the blade edge side. The cutting edge may have various sawtooth shapes, but in soft raw meat, the cut sliced meat pieces may be dragged, so keep it straight and scrape it from both sides or one side to the slope, and make the tip sharpened in a chevron shape. It is preferable to do.

  The band knife 13 is arranged so that the cutting edge is close to the receiving blade surface of the receiving blade frame 10 attached to the front end of the meat box 3 while maintaining the position relative to the abutting plate 14 (desirably contacting lightly). To do. The band knife 13 is inclined to the state shown by the phantom line in FIG. 1, and the cross-sectional shape of the blade has a rake angle of about 20 degrees with respect to the tangential direction on the arcuate receiving blade surface in a side view shown in FIG. In addition, the traveling surface of the band knife 13 (the plane on which the band knife 13 travels) is positioned so that the return traveling path is located on the machine base 1 side.

  The band knife 13 is wound around a pair of pulleys 17 and 17 (FIG. 2) that are rotatably supported on the left and right of the machine base 1, and either one of the pulleys 17 is installed in the machine base 1. It is connected to a motor (not shown) and rotated so that the band knife 13 travels in one direction.

  In the cutting action range in which the band knife 13 slices the front end portion of the meat block M, a guide plate 18 is provided that holds and guides the band knife 13 so as not to bend due to cutting resistance. The guide plate 18 is made of a plate material, and a narrow groove 18a is engraved on the lower end surface thereof as shown in FIG. 3, and the band knife 13 is fitted with the anti-blade edge side 13b in the narrow groove 18a leaving the blade edge side 13a. On the other hand, the upper end is extended upward to cover the swinging range of the meat box 3 and fixed to the machine base 1.

  The return side travel path of the band knife 13 (on the opposite side of the cutting action range guided by the guide plate 18) is located on the machine base 1 side, and is configured so that the band knife 13 can travel freely. . In the travel path of the band knife 13, a polishing device for the blade edge, a scraper for cleaning the blade surface, and the like (not shown) are provided. Moreover, the non-driving side pulley 17 is slidably supported as a tensioning device for the band knife 13. Further, the band knife 13 is configured so that it can be easily attached and detached by opening the cover 22.

  The blade is not limited to a band knife, and a linear reciprocating blade can be used instead of the band knife.

  The function of the meat slicer configured as described above will be described. First, the distance between the upper end of the contact plate 14 and the cutting edge of the band knife 13 is adjusted and set by the expansion / contraction device 16 of the contact plate 14 so as to obtain a desired slice thickness. Next, the raw meat block M is mounted on the conveying belt 5 of the meat box 3 and the roller 6 is driven by a servo motor (not shown) until the leading end of the meat block M reaches the contact plate 14. A motor (not shown) connected to the pulley 17 on which the band knife 13 is hung and a motor 12b of the crank device 12 that swings the meat box 3 are driven. At the same time, the telescopic device of the pressing tool 7 is actuated to hold the vicinity of the front end of the meat block M against the bottom surface from above with the pressing tool 7. In this state, the meat block M is sliced (cut) by the cutting edge of the band knife 13 whose front end portion travels as the meat box 3 moves upward, and is taken out as a sliced meat piece m obliquely upward from the cutout opening.

In front of the machine base 1 (on the right side in FIG. 1), a receiving device mounting base 30 is provided integrally or detachably with the machine base 1. The receiving device mounting stand 30 of the illustrated embodiment is constituted by a frame body having support legs 30a, and is connected to the machine base 1 by a stay 30b.

  A conveyor 34 as a receiving device is provided on the upper portion of the receiving device mounting base 30. The conveyor 34 is configured by an endless body stretched between a pair of rollers 31 and 32 and a driving pulley 33 provided at the front and rear. Conveyor 34 has its starting end (on the side of roller 32) positioned close to the upper end surface of contact plate 14, and obliquely upward from the upper end surface of contact plate 14 along the lower surface of sliced meat piece m cut out from the cutout opening. Thus, a receiving surface for receiving the sliced meat piece m is formed. When the gap between the starting end portion of the conveyor 34 and the upper end surface of the plate 14 is set to the minimum dimension that the conveyor 34 can travel, even when slicing a small meat block M, the sliced meat can be reliably received without dropping. it can. The other end portion (on the roller 31 side) is located at a slice meat take-out position T installed at the front, and extends continuously and integrally from the start end portion to the take-out position T, and also serves as a carry-out conveyor. .

  The sliced meat piece m transferred on the conveyor 34 is manually removed near the sliced meat piece extraction position T and transferred to a storage container such as a tray or a pie lesh. In the illustrated embodiment, the conveyor 34 has an endless belt with a smooth surface, and the sliced meat pieces are easy to adhere and the posture is not disturbed, and the familiarity with the scraper is better and the cleaning is easier than the conveyor with protrusions. It is said.

  The conveyor 34 is supported by a conveyor frame 34a, and the starting end of the conveyor 34 holds a position close to the upper end surface of the abutment plate 14 and supports the abutment plate 14 provided in the machine base 1. 15 is connected. Further, guide rollers 34c are pivotally supported below the side plates 34b of the conveyor frame 34a on the terminal end side of the conveyor 34, and are fitted into guide grooves 30c provided on the receiving device mounting base 30. Therefore, when adjusting the slice thickness, if the abutment plate 14 is moved by the link mechanism 15, the starting end of the conveyor 34 moves while maintaining the position relative to the upper end surface of the abutment plate 14, and the guide roller 34c rolls along the guide groove 30c so that the conveyor frame 34a moves.

  An arcuate guide plate 35 is installed on the receiving device mounting base 30 below the conveyor 34 in the vicinity of the starting end, and the conveyor 34 at the starting end is provided on the lower surface of the sliced meat piece m cut out from the cutting opening. A receiving surface for receiving the sliced meat piece m is formed so as to extend obliquely upward from the upper end surface of the abutting plate 14. In the embodiment, as shown in FIG. 3, the receiving surface is a smooth curved surface with the front (right side in FIG. 3) being high and projecting outward. You may form this curved surface in circular arc shape in side view.

  A pressing tool 40 is provided above the conveyor 34 to press the sliced meat piece m being cut out toward the receiving surface of the conveyor 34. In FIG. 3, two pressing tools 40 are provided at the front and rear. In the illustrated embodiment, as the pressing tool 40, a plurality of thin spring wires parallel to each other are provided in a comb shape across the width of the conveyor, and the slice meat m contact surface of the pressing tool 40 and the receiving surface of the conveyor 34 are used. Is set to be equal to or smaller than the thickness of the sliced meat piece m. Further, the pressing tool 40 and the receiving surface of the conveyor 34 cover and hide the cutting edge 13a of the band knife 13 so that a human fingertip cannot reach the cutting edge 13a.

  The drive pulley 33 is connected to a servo motor 36. The servo motor 36 is electrically connected to a servo motor 12b for driving the crank device 12 that swings the meat box 3, and is interlocked at the timing described below.

In FIG. 4, the horizontal axis represents the rotation angle of the crankshaft of the crank device 12, and the vertical axis represents the moving speed of the meat box 3 and the traveling speed of the conveyor 34. The movement speed of the meat box 3 changes sinusoidally with the rotation angle of the crankshaft, and when the meat box 3 reaches the vicinity of the upper end of the sine wave (point A in FIG. 4), as shown in FIG. The meat block M is cut into sliced meat pieces m. The cut sliced piece m is guided along the receiving surface of the arcuate conveyor 34 at the starting end. At this time, the conveyor of sliced meat pieces is synchronized by synchronizing the moving speed of the conveyor 34 with the moving speed of the meat box 3 during the time zone in which the meat block M is cut (from point A to point B in FIG. 4). The reception to 34 can be performed smoothly. In FIG. 4, the traveling speed (V in FIG. 4) near the point of time at which the sliced piece m of the conveyor 34 is received is set to a constant speed that substantially matches the maximum moving speed of the meat box 3. It is only necessary that the timing at which the slices move and the timing at which the sliced meat pieces m are cut out from the meat block M in the meat box 3 are synchronized.

On the other hand, within the range excluding the time zone in which the meat block M is sliced while the meat box 3 is moving up, that is, within the range excluding the vicinity of the reception time zone of the sliced meat piece m of the conveyor 34 (goes from the point B in FIG. 4). Only during the period from point A to point A), as shown in FIG. 4, the conveyor speed is reduced from the speed at which the slice m is received and the slice on the conveyor 34 is stopped. You may adjust the space | interval of the meat piece m. Note that the deceleration includes moving the conveyor 34 backward.

  When the conveyor 34 is moved backward, an adjusting means is provided so that the receiving surface of the conveyor 34 can be moved to and away from the cutout opening. For example, as shown in FIG. 5, the roller 32 has a relatively large diameter, is supported by the support arm 32a, and a driving device such as a swing motor 32b is connected to the support arm 32a. The slice meat piece m placed on the receiving surface of the conveyor 34 is moved away from the cutout opening without being obstructed by the pressing tool 40 described later. Further, it is convenient to change the distance between the roller 32 and the cutout opening according to the number of stacked sliced meat pieces m placed on the conveyor 34.

  In FIG. 4, the traveling speed of the carry-out conveyor 34 in the range excluding the vicinity of the time when the sliced meat piece m is received is substantially constant. However, the running speed can be adjusted, and the sliced meat piece m can be easily taken out from the carry-out conveyor. You may be able to do it.

  Furthermore, it is preferable that the conveyor 34 can be adjusted so that the stop or deceleration start point (point D in FIG. 4) is advanced or delayed. Further, it is preferable that the conveyor 34 can be adjusted so as to advance or delay the return point (point A in FIG. 4) from the stop or deceleration state to the high speed. That is, if the conveyor stop or deceleration start point (point D in FIG. 4) is advanced or the conveyor stop or deceleration state returns to high speed (point A in FIG. 4) is delayed, the slices that are relatively cut out The speed of the conveyor 34 becomes slower than the speed of the meat pieces m, and as a result, the slice meat pieces m taken out on the conveyor 34 are slackened (wrinkled), and are easily grasped when the slice meat pieces m are picked up by hand at the take-out position T. . Conversely, when the conveyor 34 stops or decelerates (D point in FIG. 4) is delayed, or when the conveyor stops or decelerates to the high speed (point A in FIG. 4), it is cut out relatively. The speed of the conveyor 34 becomes faster than the speed of the sliced meat piece m. As a result, the sliced meat piece m taken out on the conveyor 34 is stretched, and sagging (crease) does not occur. In practice, both aspects are used as appropriate.

  As shown in the embodiment, when the meat box 3 can be moved up and down by the crank mechanism 12 and the traveling speed of the conveyor 34 near the time when the sliced piece m is received is set to a constant speed that substantially matches the maximum movement speed of the meat box 3. Since the traveling speed of the conveyor 34 gradually increases relative to the moving speed of the sliced meat piece m toward the end of cutting, the sliced meat piece m is stretched. In addition, the number of reciprocating movements per unit time of the meat box 3 can be adjusted, and the stop of the carry-out conveyor 34 or the reduction of the traveling speed is set to be performed only when the number of reciprocating movements of the meat box 3 per unit time is large. May be.

  The meat box 3 is returned to the swing start point by the crank device 12 after the upper surface of the receiving blade body 10 that receives the lower surface of the meat block M passes through the blade edge and reaches the swing return point (point B in FIG. 4). Next, the pressing tool 7 is lifted, and the conveying belt 5 moves by an amount corresponding to the slice thickness to feed the meat block M. Then, the pressing tool 7 presses the meat block M again, and the slicing operation is repeated as described above.

  In the above-described embodiment, the receiving device mounting platform 30 is provided in front of the machine base 1 (on the right side in FIG. 1), and the sliced meat piece m cut out from the meat block M by the band knife 13 moves on the conveyor 34. It is unloaded, and is manually removed in the vicinity of the take-out position T of the sliced meat piece m, and transferred to a storage container such as a tray or a pie lesh.
