DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slicer for cutting food such as meat chunks, fish and vegetables into a desired thickness.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional food slicer is provided with a feed conveyor (1) and a discharge conveyor (2) across a rotation transfer path of a rotary slice blade (5).
The food (7) such as the meat chunk (7a) sent by (1) is sliced by the slicing blade (5) to a thickness corresponding to the feeding amount,
This is delivered to the discharge conveyor (2) and discharged.

[0003] On both sides of the rotational transfer path of the slice blade (5),
The transition path and the upper curved surfaces (11) and (21) of both conveyors (1) and (2)
In between, two guide stands (6) and (60) are provided. When the feed speed of the discharge conveyor (2) is higher than that of the feed conveyor (1), the slice pieces (71) are
(2) The upper slices fall to the discharge side, and the adjacent slice pieces are arranged in a shifted and overlapped state, so-called shifted cutting can be performed.

[0004]

[Problems to be solved by the present invention]
There were no problems with sliced slices such as radishes and carrots, but when sliced meat chunks, the overlapping length of adjacent sliced slices was not constant, and between adjacent sliced slices In some cases, the gap (8) may be irregularly formed. The applicant has examined the reason why the meat chunk cannot be stably cut and found the following conclusion.

The upstream receiving tray (6) serves only to guide the meat chunk (7a) straight from the feed conveyor (1) to the transition path of the slice blade (5). Since the slice is sliced only by the slicing blade (5) moving downward from the, the sharpness is poor. Therefore, when the slicing blade (5) passes through the pedestal (6), a piece of meat is dragged between the slicing blade (5) and the pedestal (6), so that it is somewhat likely.

As described above, the slice pieces (7
1) has a dripping (72) at the lower edge of the cut due to poor sharpness, and when the sliced piece is pushed out to the downstream guide table (60), the dripping (72) is There may be a shift from the platform (60) to the transition path of the slice blade (5). When the slicing blade (5) passes from the top where the sag (72) has shifted, the sag (72) is pressed against the corner of the guide table (60) and is temporarily caught, preventing the advance of the sliced piece, and Piece (71) and belt
Slip occurs with (4). For this reason, the displacement of the adjacent slice pieces (71) (71) becomes irregular.

[0007] If the downstream guide table (60) of the two guide tables (6) and (60) is omitted, the catch between the slice piece (71) and the guide table (60) is eliminated. Slices fall from the gap between the conveyor (1) and the discharge conveyor (2),
It cannot be staggered. The present invention is to clarify a slicer which can be beautifully shifted by devising a roller (3) or a belt of a discharge conveyor (2).

[0008]

The food slicer according to claim 1 is:
In a food slicer provided with a food feeding conveyor (1) and a food discharging conveyor (2) on both sides of a rotary transfer path of a rotating slice blade (5), the discharging conveyor (2) is provided by rollers provided at an upstream end and a downstream end. A plurality of narrow belts (4) are stretched endlessly between the belts, and a plurality of protrusions (not shown) are provided on the peripheral surface of the roller (3) on the upstream side so as not to hinder the movement of the belt (4). 31)
Is provided higher than the belt (4) wound around the roller (3), and is provided between the upper curved surface at the downstream end of the feed conveyor (1) and the rotation transfer path of the slice blade (5). 6) is deployed,
Upper curved surface (21) at the upstream end of discharge conveyor (2) and slice blade
It is open to the transition path of (5).

The food slicer according to claim 2 is a roller (3)
Instead of the protrusions (31), a number of protrusions (3
It protrudes 1).

According to a third aspect of the present invention, in the food slicer according to the first or second aspect, the upstream end of the discharge conveyor (2) can adjust the height position and the approach position with respect to the guide receiving table (6). Has been deployed.

[0011]

[Operation and Effect] Since the space between the upper curved surface at the upstream end of the discharge conveyor (2) and the transition path of the slice blade (5) is open, the slice is cut at the moment the slice is cut off from the meat mass by the slice blade (5). The piece is about to fall, but is caught by the protrusion (31) protruding from the roller (3) or the belt (4),
Due to the rotation of (3), the paper is sent in the transport direction of the discharge conveyor (2). Therefore, the slice pieces do not slide down from the upstream end of the discharge conveyor (2).

An upper curved surface (21) at the upstream end of the discharge conveyor (2).
Since there is no guide table (60) as in the related art between the transfer path of the slice blade (5) and the slice piece (71) and the guide table (60)
The slip of the slice (71) and the belt (4) due to the hooking of the slice is eliminated. Thereby, according to the speed difference between the feed conveyor (1) and the discharge conveyor (2), the slice pieces can be regularly shifted and overlapped on the discharge conveyor (2).

When the projection (31) is provided on the roller (3), the following effect is further obtained. When the sliced piece (71) is a thin piece of meat, the sliced piece immediately after slicing is caught on the projection (31), wraps around the roller (3) and tries to rotate together with the roller, but the belt (4) is rotated by the roller (3). In order to separate the slice piece (71) from the projection (31) when the slice piece (71) is separated from the circular arc surface, the slice piece (71) smoothly moves to the downstream side on the belt (4).

If the height of the discharge conveyor (2) on the upstream side and the approach distance to the rotational transfer path of the slice blade (5) can be adjusted, the type of food to be sliced and the slice thickness can be adjusted. Then, cutting can be performed under optimal conditions.

[0015]

FIG. 1 shows a main part of a food slicer according to the present invention. As is well known, a feed conveyor (1) and a discharge conveyor (2) are sandwiched between rotation transfer paths of a slice blade (5). And are arranged facing each other.

The slicing blade of the embodiment is a so-called sword blade having a substantially crescent shape. The slicing blade rotates around one end of the slicing blade to cut the food, but is not limited thereto. It is also possible to cut the blade by revolving it while rotating it. The following slice blade rotation transition path is
It is a self-transferring path centered at one end on a naginata blade, and a publicly-transferring path on a disk blade.

The feed conveyor (1) and the discharge conveyor (2) are each connected to a feed speed adjusting device (not shown) so that the feed speed can be adjusted. A guide table (6) is provided in the gap between the upper curved surface (11) at the downstream end of the feed conveyor (1) and the rotational transfer path of the slice blade (5), and the upper surface (62) of the table is It is inclined gradually higher toward the downstream side, and the upper edge of the downstream end is a cutting edge (61) over the entire length. This is not a mere edge, but a consciously formed cutting edge to form a fixed blade for the rotating slice blade (5).

The discharge conveyor (2) includes a plurality of narrow belts (4) between an upstream roller (3) and a downstream roller (not shown).
Are stretched endlessly. Upstream roller
On the peripheral surface of (3), a large number of protrusions (31) are provided at regular intervals in the circumferential and axial directions at portions not interfering with the movement of the belt (4). Protrudes slightly higher than the belt (4) wound around the roller (3). The protrusion (31)
Regardless of the shape of the small block piece as shown in FIG.
In short, it is only necessary that the sliced piece can be scratched and lifted along the curved surface of the roller.

Roller (3) at the upstream end of the discharge conveyor (2)
Are mounted on the base 9 at both ends via a pair of L-shaped brackets 91 so that the height position and the front-back position can be adjusted. The bracket (91) is an oblong hole (94) opened in the horizontal piece (92).
And the front and rear positions can be adjusted by a margin of the fixing bolt (96) fitted in the hole. The roller (3) is attached to the bracket (9
Positioning can be performed in the vertical direction by a margin of the vertically long hole (95) formed in the vertical piece (93) of (1) and the roller support shaft (97) fitted in the hole. The discharge conveyor (2) is a roller at the upstream end as described above.
In addition to adjusting the position of (3), the entire discharge conveyor (2) may be provided so as to be positionable in the height direction and the front-back direction.

A tension roller (98), which is spring-biased to prevent the belt (4) from loosening, is always provided on the discharge conveyor (2) by pressing the belt (4). Roller above
The minimum clearance between the projection (31) of (3) and the guide table (6) must be slightly larger than the thickness of the slice blade (5). The position may be set optimally according to the type and thickness of the food to be sliced. An opening is provided between the upper curved surface (21) at the upstream end of the discharge conveyor (2) and the transfer path of the slice blade (5).

However, the feeding speed of the discharge conveyor (2) is set higher than that of the feed conveyor (1), the two conveyors are operated, and the meat conveyer (7a) is sliced by the feed conveyor (2) into slice blades (5). Side. By the rotation of the slicing blade (5), the meat mass is sliced to a thickness corresponding to the feed speed of the feed conveyor (1) and delivered to the discharge conveyor (2).

If the upper edge on the downstream side of the pedestal (6) is a cutting edge (61) as in the embodiment, this becomes a fixed blade, and it cooperates with the slice blade (5) which is a movable blade. The slice of meat (7a) can be sharply sliced, and does not cause dripping at the lower end of the sliced piece, unlike a slice relying only on the conventional slice blade (5).

Since the space between the upper curved surface at the upstream end of the discharge conveyor (2) and the transition path of the slice blade (5) is open, the slice pieces ( 71) is about to fall, but is caught by the protrusion (31) protruding from the roller (3) or the belt (4), and the roller (3)
Is fed in the direction of conveyance of the discharge conveyor (2), so that it does not slide down from the upstream end of the discharge conveyor (2).

Upper curved surface (21) at the upstream end of the discharge conveyor (2)
Since there is no guide table (60) as in the related art between the transfer path of the slice blade (5) and the slice piece (71) and the guide table (60)
The slip of the slice (71) and the belt (4) due to the hooking of the slice is eliminated. By repeating the above operation, the slice pieces can be regularly shifted and overlapped on the discharge conveyor (2) according to the speed difference between the feed conveyor (1) and the discharge conveyor (2). The greater the difference in speed between the feed conveyor (1) and the discharge conveyor (2), the greater the displacement of the sliced pieces on the discharge conveyor (2).

When the slice piece (71) is thin, it is caught by the projection (31), wraps around the roller (3), and tries to rotate together with the roller, but the belt (4) is separated from the arc surface of the roller (3). At this time, since the slice piece (71) plays a role of separating the slice piece (71) from the projection (31), the slice piece (71) smoothly moves to the downstream side on the belt (4).

In addition, if the height on the upstream side of the discharge conveyor (2) and the approach distance with respect to the rotational transfer path of the slice blade (5) can be adjusted, the type of food to be sliced and the slice thickness can be adjusted. Then, cutting can be performed under optimal conditions. The present invention
It can be implemented simply by replacing the existing discharge conveyor (2) with the above-mentioned discharge conveyor (2).

In practicing the present invention, the slice blade (5)
The intermittent operation in which the feeding conveyor (2) is stopped for a fixed short time every time a predetermined number of slices are cut off makes the belt (4)
Above, a gap can be made between the units, and it can be shifted and cut. This is convenient when packaging is performed for each unit.

As another embodiment of the present invention, as shown in FIG. 4, even if the belt (4) itself is provided with a short protrusion (31) outwardly, the same effect as described above can be obtained. it can. In this case, the belt (4) is a belt-shaped belt whose width corresponds to the length of the roller (3) or a string-shaped belt (4) having a rectangular cross section, and the direction of the protrusion (31) is outward. We have to keep it the same.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims.
