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

Ham slicers that slice cylindrical ham at room temperature are commonly found in retail butcher shops. This has the structure disclosed by patent document 1 (Unexamined-Japanese-Patent No. 37-29973, for example).

In other words, in the ham slicer disclosed in Patent Document 1, the rotary knife is axially supported so as to rotate at an inclined line by forming an arbitrary angle at one of the corners of the apparatus box at an axis thereof, and along the surface of the rotary knife. A bucket is provided at the distal end of the swing supported by the shaft on one side of the equipment box to swing, and the crank arm provided at the distal end of the rotation shaft provided at the swing box and the equipment box is connected by a connecting rod. .

In the slicer, since the ham, which is almost cylindrical, is sliced at room temperature, as in Patent Literature 1, the rotary knife and the sugar plate are equally inclined in the same direction. It is configured to move. The bucket bends a rectangular plate into an L shape, and the side ends thereof contact each other with the rotary knife so that the bucket is inclined in the opposite direction of the rotary knife. For this reason, the ham accommodated in this also inclines, and since the lower end is cut | disconnected sequentially, the movement | ejection of taking out raw ham is performed by the weight of the ham itself, and it slides off the wall surface of a bucket automatically. Thus, the taking out operation is simple. At the same time, since the ham was cut with a rotary knife when the bucket was moved upwardly by the swinging rod, the ham is likely to be lifted from the bucket wall, so the ham is pressed against the bucket wall and brought into close contact with the bucket. A simple pressing piece such as a light pressing that does not require a suppressing mechanism is sufficient, and therefore, the operation of the mechanism is extremely easy.

However, when the apparatus of patent document 1 is used when sliced the meat block of the chilled state (the article temperature before and behind 0 degreeC) which this invention makes object, there exists a following problem.

The slicer slices the cylindrical ham at room temperature, so that by tilting the meat box, the ham automatically slides down the wall of the meat box toward the blade surface of the round knife by the weight of the ham itself. However, in the chilled meat block of the present invention, the meat block may rise to a positive temperature during slicing, which not only becomes soft but also increases adhesiveness and adheres to the wall surface, resulting in poor slipping. Therefore, only by tilting the meat box, there is a problem that the meat block does not slip smoothly on the wall surface of the meat box normally. In addition, a problem arises in that the slice thickness is not stabilized because slippage becomes poor.

Moreover, since the ham sliced by a ham slicer is comparatively light weight, a ham slicer is also comparatively light weight, and it can use it by inclining it. On the other hand, when slicing a meat block in a chilled state, the weight of the meat block and the meat box is also large, and when such a slicer is inclined, a portion that is mechanically biased to one side is uneven, and it is uneven with time (usage). Abrasion occurs and a rattling occurs.

In particular, if rattling occurs in each node of the shaft or crank mechanism supporting the swinging rod, the entire bucket is inclined around the axis, and in particular, the tip of the meat block (ham) mounting surface located below approaches the plate. Going. Therefore, the front end surface of the bucket cannot reciprocate while maintaining parallel to the round knife, and the slice thicknesses are not equal. Going further could lead to an accident that the tip of the bucket hits the round knife.

When slicing soft meat blocks in the chilled state with the inclined ham slicer, the front end faces of the meat blocks are hard pressed down by the weight of the meat blocks themselves on the plate and the round knife surface, and the surface is washed and damaged. , Meat debris is attached to the cut surface, which reduces the quality.

In view of such a problem, the meat meat slicer which is generally used when slicing the meat block in the chilled state (product temperature before and after 0 degreeC) is typical, for example, patent document 2 (patent publication 2003-170390) As shown in Fig. 1, the crate rotates linearly on the rail by a crank mechanism while rotating the round knife about the horizontal axis in the vertical plane, following the front end of the meat box in the rotary plane of the round knife. At the same time, there is a horizontal reciprocating slicer with a bottom conveyor for discharging the meat block toward the front end of the meat box at the bottom of the meat box.

In the meat slicer disclosed in Patent Document 2, the meat box reciprocates linearly on the rail. However, rattling is likely to occur between the rail and the contact surface of the meat box. As a countermeasure, if rattling is restricted, not only the movement of the meat box is worsened, but also the frictional resistance of the contact surface is increased and the required power is increased. For this reason, it is difficult to keep the positional relationship between the front end surface of the meat box and the cutting knife end of a round knife constant. In particular, in order to reliably cut smooth raw meat (chicken state) and meaty meat, it is effective to minimize the gap between the front end of the meat box and the cut end of the round knife as much as possible. In reciprocating and cramped meat boxes, there was a limit to the small gap.

Moreover, the occurrence of rattling as described above may cause vibration or noise of the meat slicer, thereby deteriorating the working environment.

In addition, a side wall plate is provided at the left and right ends of the meat box in the horizontal reciprocating slicer in which the meat box linearly reciprocates on the rail as described above. The burden on the worker was high because the meat block had to be lifted and introduced from the upper side of the meat box beyond the upper edge of the side wall plate located on the right side as viewed from the front of the meat box among the side wall plates.

Moreover, in the conventional meat slicer, the meat box which reciprocates was exposed, and was dangerous.

In the light of the above-described phenomenon, the Applicant disclosed in Patent Document 3 (Japanese Patent Laid-Open No. 2006-35349) to support a rail as in the prior art by allowing the meat box to reciprocate in a horizontal direction around a longitudinally extended swing shaft. We developed and proposed a meat slicer using a band knife as a reciprocating device for meat boxes that do not need it. However, since the apparatus of patent document 3 uses a band knife, the structure is complicated and requires special consideration for adjustment and maintenance.

The present invention solves the problem associated with the meat slicer having a meat box linearly reciprocating on the conventional rail described in Patent Document 2 described above, reduces the occurrence of rattling when moving the meat box, It is possible to maintain a constant positional relationship between the front end face and the cutting knife end of the round knife, and in particular, it is possible to reliably cut the soft raw meat or the meat-rich meat block, so that vibration from the meat slicer due to rattling occurs It is an object of the present invention to provide a meat slicer which is low in noise and the like, which makes it easy to supply the meat block into the meat box, and furthermore, a round knife is used for the cutting knife for easy adjustment and repair and safe operation.

It is preferable to swing toward the right side of the round knife while drawing the swing trajectory.

In the ham slicer disclosed in Patent Literature 1, since the bucket is arranged to swing in a vertical direction with respect to a round knife, the loaded material (ham) has its own weight with respect to the bottom (the wide side where the ham is placed side by side in FIG. 3). There is a problem that it does not work and floats from the bottom of the bucket by centrifugal force and is not stabilized. On the other hand, in the embodiment of the present invention, as described later with reference to Fig. 1, the meat box swings to the right in a substantially horizontal state, so that the weight of the meat block is applied to the bottom of the meat box, and the meat is fed by centrifugal force. There is little rise of block and is stable. Furthermore, in the present invention, since the feeding device is provided on the bottom surface of the meat box, in this embodiment, more stable feeding is possible by the mutual action of both.

Furthermore, in the present invention, it is preferable that a side conveyor belt is provided on the meat block arrangement surface of the meat box, as viewed from the front of the meat box, at least on the right wall end of the meat box, to direct the meat block toward the front end of the meat box. Do.

Further, a meat box cover covering the meat box throughout the reciprocating swing range of the meat box is provided supported by the gas, and at least the meat block, which is a raw material, can be supplied to the meat box which is stopped at the start position of the reciprocating swing of the meat box. Feed opening having a width that can be opened in the meat box cover, the opening of the supply opening has a size that can block the opening, and the meat cover is provided to open and close the supply cover that can be seen from the outside It is preferable to set it as a slicer.

The said meat box is arrange | positioned so that it may become the lowest position in the reciprocating oscillation range of a meat box at the start position of a reciprocating oscillation, and the said supply port is opened in the position which opposes the block meat arrangement surface which is stopped in a start position. It is preferable to set it as.

Thus, the horizontal support shaft 13 extends as much as possible to the inner width dimension of the body 1 (dimension shown in FIG. 2), and is rounded with the front end of the meat box 5 supported by the oscillator 9. The gap with the cutting knife tip of the knife 4 is maintained precisely.

In addition, both ends of the horizontal support shaft 13, as shown in Fig. 2, the horizontal shaft on which the round knife 4 is fixed while maintaining the horizontal state at the bottom of the base 1 by the fasteners 14 and 14 ( 3) fixed to be parallel to In the fitting portion of the connection pipe 12 and the horizontal support shaft 13, using a host bearing member such as a ball bearing, so as not to rattling as possible, is configured to allow the swinging body (9) to smoothly swing.

In the meat box 5, the front end of the meat box 5 (the sinus end surface of FIG. 2) is in contact with the rotating surface of the round knife 4, and the center of the horizontal support shaft 13 in FIG. The crank device 16 reciprocates on the horizontal arc surface centered on the shaft center.

The crank device 16 is provided to reciprocate the meat box 5 mounted on the swinging body 9 in a predetermined range, centering on the shaft center of the horizontal support shaft 13, and the swinging body 9 Connecting rod 17 connected to a part of), a driving motor 25, a reduction device 26, a clutch 27, etc., installed at the bottom of the base 1 connected to the other end of the connecting rod 17. Consists of A servo motor may be used as the drive motor 25. In addition, since the crank apparatus 16 itself is a well-known structure, the detail is abbreviate | omitted.

The swing range of the meat box 5 is the position where the front end surface of the meat box 5 is separated from the rotational surface of the knives 4 when viewed from the front of the meat box 5 (in the state shown in FIG. 1) (FIG. 1). The position indicated by the broken line at the starting point is set as the start position, and the position at which the front end surface of the meat box 5 overlaps the rotating surface of the round knife 4 (the position indicated by the dashed-dotted line in FIG. 1) is the end position. That is, the meat box 5 reciprocates oscillating centering on the shaft center of the horizontal support shaft 13 as a swing range between a start position and an end position.

In the starting position, by supplying the meat block to the meat box 5 and starting the operation, the front end of the meat block sent out from the front end of the meat box 5, the meat box 5 swings so that the round knife 4 It is pressed and sliced on the right side of the pan, cut into slice pieces at the end position, received directly by the operator's hand, and placed on a suitable dish or the like.

The meat box 5 is basically the same structure as the conventional meat slicer, and the meat block placed on the bottom portion, which is the placement surface of the meat block, is placed toward the front (round knife 4 side) (the ground in Fig. 1). Bottom conveyor belt 6 is provided which exits from inside to close to the inside, from right to left in FIG. 2 and from top to bottom in FIG. 3, and the bottom conveyor belt 6 moves intermittently by any suitable means known in the art. do.

The meat box 5 may be formed in a tubular shape by placing a side wall plate at the front end of the meat box 5 (that is, in the state of FIG. 1) at the left and right ends as in the conventional type. Since the side wall plate on the left side is not directly related, illustration is omitted.

The side wall plate 7 placed on the right end of the meat box 5 is made of a plate material in the conventional type, but in this embodiment, the side conveyor is similar to the bottom conveyor belt 6 provided in the bottom part. The belt 8 is provided and comprised. The side conveyor belt 8 is provided with suitable drive means so that it can move in synchronization with the bottom conveyor belt 6, and it moves mechanically and electrically by a well-known method.

In addition, the side wall board 7 in which the side conveyor belt 8 is mounted is not necessarily in an upright state (state shown in FIG. 1) with respect to the bottom conveyor belt 6, and the upper part is wide enough toward the outer side suitably. You may incline to open.

In addition, the bottom conveyor belt 6 and the side conveyor belt 8 are configured such that when the meat box 5 stops at the start position (dashed line indicated in Fig. 1), the arranged meat blocks are sent out only by a predetermined amount. It is preferable to drive using a motor (not shown) or the like. In this embodiment, in the starting position, as shown in Fig. 1, the meat box 5 is inclined outward from the starting position, and the arranged meat block is leaned on the side conveyor belt 8. Therefore, the transmission can be performed reliably. The bottom conveyor belt 6 and the side conveyor belt 8 may be roller conveyors.

At the distal end of both conveyor belts 6 and 8, both belts 6 and 8 have a water conductor (not shown) close to the cutting knife end of the round knife 4 similar to the conventional apparatus. It is provided by connecting along the tip part.

In the meat box 5, as in the conventional type, an upper feed device made of a roller with a projection or a pressing device that presses the upper surface of the meat block when the meat block is sliced, has an operating position and an upper portion of the meat box 5. It may be provided to be switched to the retracted position in order to facilitate the supply of the meat block by opening the, but the illustration is omitted in the present embodiment.

In addition, although the detailed illustration is abbreviate | omitted, in the front end part of the meat box 5, the front end surface of the meat feed block sent out is mutually adjusted in the front-back direction, and the sugar plate which determines slice thickness is mounted like a conventional type.

1 to 3, the cover 1b formed of a thin plate is suitably provided on the upper part of the base 1 so as to cover the upper surface of the base 1, and the whole reciprocating range of the meat box 5 is provided. The meat box 5 is wrapped. A feed port is opened in the meat box cover 1b, and the supply port has an area capable of supplying at least a meat block, which is a raw material, to the meat box 5 at a stop at the start position of the reciprocating motion of the meat box 5. . That is, the supply port is inclined so as to stick to the meat box 5 at the position opposite to the meat block placement surface of the meat box 5 stopped at the start position of the swing movement, as shown in FIG. It is formed in the upper surface of), and the supply port has the width | variety equivalent to the meat block arrangement surface.

In the opening of the supply port, the supply port cover 1a is provided to be opened and closed to the meat box 1b via the hinge 1c. Here, the supply port cover 1a has the size which can block an opening part, and can look inside from the outside. That is, in the illustrated embodiment, as shown in FIG. 2, the cover 1a is formed of a thin plate, and a plurality of see-through holes 1d are formed in the thin plate to prevent intrusion of a finger. However, the configuration of the cover 1a that allows the inside to be viewed from the outside is not limited to the form of FIG. 2, but, for example, the cover 1a may be formed in a fence shape using a plurality of thin rod materials. Alternatively, the cover 1a may be formed of a transparent material such as hard resin.

In order to make it easier to supply the meat block to the meat box 5 at the start position when the meat box 5 reciprocates, the meat box 5 is located at the lowest end (dashed line position shown in Fig. 1) in the reciprocating swing range of the meat box 5. In addition to positioning the meat box 5, the supply port is opened at an upper surface position of the meat box cover 1b facing the block meat arrangement surface of the meat box 5, which is stopped at the start position.

The swinging body 9 which supported the meat box 5 as mentioned above centers on the axis of the horizontal support shaft 13 provided in the bottom part of the base 1 below the round knife 4, The swinging movement between the inclined state (dashed line position shown in FIG. 1) and the nearly upright state (an advantage chain line position shown in FIG. 1) in which the front end surface of the meat box 5 polymerizes to the round knife 4 As shown in FIG. 1, when the crank apparatus 16 is arrange | positioned by dividing the space space on the opposite side to the horizontal support shaft 13 by the partition 1e, the base body 1 can be comprised compactly.

In the present invention, a round knife rotates in a vertical plane around a horizontal axis at a fixed position, and with respect to the round knife, the swinging body is pivotally supported around the axis of the horizontal support shaft attached to the bottom of the base. A meat box having a feeding device is provided on the side of the half shaft, and the meat box is configured to reciprocate while the front end face of the meat box is in contact with the rotating surface of the knives between the starting position and the end position. Compared to the apparatus using the rail like the conventional apparatus described in the present invention, the occurrence of rattling is significantly less, and the movement of the meat box becomes extremely desired.

Moreover, in this invention, the conveying apparatus which consists of a bottom conveyor which sends a meat block toward the front end of a meat box is provided in the bottom part of a meat box, compared with sending out by self weight like the ham slicer of patent document 1, , Stable feeding is possible.

In the ham slicer described in Patent Literature 1, since the bucket is arranged to swing in a vertical direction with respect to a round knife, the loaded material (ham) is self-weighted with respect to the bottom (the wide side where the ham is placed side by side in FIG. 3). It does not work and floats from the bottom of the bucket by centrifugal force and is not stable.

On the other hand, in particular, the axis of the horizontal support shaft of the rocking body of the present invention is located on the left outer side of the vertically downward position of the horizontal axis on which the round knife is mounted, and the meat box always shows the rocking trajectory while the right side is lowered. In the case of swinging toward the right side, the meat box swings from the substantially horizontal state to the right side, so that the meat block has a weight on the bottom of the meat box, so that the surface of the meat block due to the centrifugal force is less stable. In addition, since the meat block disposed in the meat box is sliced on the right side of the round knife, the meat box is similar to the slice operation in the conventional slicer in which the meat box reciprocates from side to side, and it is easy to take out the slice of meat by the human hand. I can do it.

Further, the meat block is disposed on the right side of the meat box, when the conveyor belt is provided with at least a side wall plate on the right side of the meat box facing the meat box toward the front end of the meat box. Even if it is leaned against the wall, it is sent out reliably.

Furthermore, in the present invention, a meat box cover covering the meat box is provided supported by the gas throughout the reciprocating swing range of the meat box, and is at least a raw material for the meat box stopped at the start position of the reciprocating swing of the meat box. A supply opening having a size to which the meat block can be supplied is opened in the meat box cover, and the opening of the supply opening has a size that can block the opening, and the opening cover can be opened and closed from the outside. In this case, the feeding operation of the meat block serving as the raw material to the meat box can be performed safely and easily.

In addition, the meat box is arranged so as to be the lowest position in the reciprocating swing range of the meat box at the start position of the reciprocating swing, and the supply opening is opened at a position facing the block meat placing surface that is stopped at the start position. In this case, the feeding operation of the meat block serving as the raw material to the meat box is performed more easily.
