JP7614641B2 - Slicing device - Google Patents

Description

The present invention relates to a slicing device that uses a round blade to cut food.

Conventionally, slicing machines cut food by cutting the food perpendicularly with a rotating circular blade, and are used in particular to cut and process food such as meat, fish, cheese, and bread into thin layers.

When using this slicing device to slice refrigerated meat into thin slices, the slices tend to stick to the rotating blade and become wrinkled or stretched, resulting in slices that are conveyed with a different shape to the cut surface of the food. This then requires the slices to be reshaped when transferred to a tray, which is time-consuming.

Therefore, a device has been disclosed in which a protrusion is provided near the tip of the blade to peel off the pieces adhering to the blade so that the pieces can be sent to the feed conveyor, which is the discharge section, while maintaining the same shape as the cut surface (see, for example, Patent Documents 1 and 2).

Japanese Patent Application Publication No. 11-129189 Special Publication No. 2020-519471

However, the above-mentioned slicing device has a protrusion on one part of the rotating circular blade, so the sliced pieces adhere to the protrusion, which rotates together with the circular blade, and are dragged along by it, making it difficult to send the sliced pieces to the feed conveyor in the same shape as the cut surface of the food.

Therefore, the objective is to provide a slicing device that does not rotate integrally with the round blade, but is equipped with a peeling means that immediately peels off the slices of food from the round blade at the same time as the food is cut.

In view of the above problems, the present invention provides a food cutting apparatus including a supply unit that supplies food to a cutting position, a cutting unit that cuts the food supplied from the supply unit into slices, and a conveying unit that conveys the slices ,
The cutting unit includes a circular blade, a drive means for rotating the circular blade and revolving the circular blade so as to move the circular blade so as to cut into the food from a vertical direction, and a peeling means for peeling off pieces adhering to the circular blade,
The peeling means has an attachment portion that is attached to the outer casing of the driving means and a peeling portion that peels off the pieces attached to the side of the circular blade, and is characterized in that it revolves together with the driving means but does not rotate simultaneously with the circular blade .

In addition to the above-mentioned configuration, it is preferable that the peeling portion is disposed with a gap between it and the side of the cutting edge of the round blade.

In addition to the above configuration, it is preferable that the peeling part is removably fixed to the attachment part.

In addition to the above-mentioned configuration, it is preferable that the peeling portion has an inclined portion that is located on the same plane as the inclined surface of the cutting edge of the round blade.

In addition to the above-mentioned configuration, it is preferable that the peeling portion has an inclined portion that is positioned approximately parallel to the inclined surface of the cutting edge of the round blade.

In addition to the above-mentioned configuration, it is preferable that the peeling portion has a protrusion formed to protrude vertically from the side surface.

In addition to the above configuration, it is preferable that the protrusion is formed to protrude in a cross-sectional shape of an approximately isosceles triangle.

According to the present invention, by fixing the peeling means at a distance from the rotating circular blade, the peeling means does not rotate at the same time as the circular blade, and the food slices can be peeled off immediately without being dragged by the steps and protrusions.In addition, since the shape of the food slices is arranged in the discharge section in the same condition as the cut surface of the food, there is no need to adjust the shape of the slices when transferring them to the tray, making it possible to facilitate the transfer operation to the tray.

In addition, the peeling means is not formed integrally with the round blade, so maintenance can be easily performed by replacing or cleaning only the peeling part.

An example of a slicing device according to an embodiment of the present invention will be described in detail with reference to Figures 1-6.

(Embodiment)
As shown in FIG. 1, the slicing device is mainly composed of a supply section 10 which supplies food 50 to a cutting position 12, a cutting section 20 which cuts the food 50 supplied from the supply section 10, and an unloading section 30 which unloads slices 51 of the food 50.

The supply unit 10 consists of a conveyor 11 arranged vertically to send the food 50 to the cutting position 12 and push it out to a predetermined thickness d, and a rack 13 that surrounds the food 50 from the conveyor 11 to the cutting position 12.

The cutting unit 20 has a round blade 21, a driving means for rotating the round blade 21 and moving the round blade 21 so as to cut vertically into the food 50, and a peeling means for peeling off the pieces 51 adhering to the round blade 21.

The circular blade 21 is a circular plate-like body with a cutting edge 22 on its outer periphery. This circular plate-like body has a cross-sectional shape that is inclined from the central attachment position to the cutting edge 22, and this cutting edge 22 is formed as a so-called single-edged blade with a sharp tip and an inclined surface 23 on one side.

The driving means has an arm portion 24 that performs a rotational motion to rotate and revolve the circular blade 21, and a reciprocating motion to move the circular blade 21 back and forth in a direction perpendicular to the food 50.

The discharge section 30 is located near the cutting position 12 and consists of a conveyor 31 that receives and discharges the pieces 51 of the food 50 cut by the cutting section 20 from below.

Next, the means for removing the cut portion 20 will be described in detail.
As shown in FIG. 2, the peeling means has a mounting portion 41 that is mounted on the exterior body 24 a of the driving means for the circular blade 21 , and a peeling portion 43 that peels off the piece 51 adhering to the side surface of the circular blade 21 .

As shown in Figures 2 and 3, the attachment part 41 is a generally fan-shaped plate-like body, and has a base end part 41a that is detachably fixed to the exterior body 24a of the driving means of the cutting part 20, and a peripheral part 42 with openings 42a, 42a to which the peeling part 43 is detachably fixed with a bolt.

The base end 41a has mounting pieces 41b, 41b erected in a roughly L-shape so that it can be detachably fixed to the exterior body 24a of the arm portion 24 of the driving means, and openings 41c, 41c through which bolts can be inserted into the mounting pieces 41b, 41b.

As shown in Figures 3 and 4, the peeling portion 43 is a plate-like body having an overall shape of an annular sector, and is formed with a cross section that is approximately L-shaped so that it is arranged approximately parallel to the side of the cutting edge 22 of the circular blade 21 with a gap t between them. It is formed so that its thickness gradually decreases toward the outer periphery, and has an inclined portion 43a and a protruding portion 43b near its tip.

The inclined portion 43a is formed so that the tip is rounded at the portion that contacts the piece 51 cut by the cutting edge 22 of the circular blade 21 and is gently inclined so as to be flush with or approximately parallel to the inclined surface 23 of the cutting edge 22 of the circular blade 21.

The protrusion 43b is formed to protrude in a substantially arcuate shape when viewed from the front in FIG. 2 in order to push out the slices 51 peeled off from the round blade 21 by the peeling part 43. As shown in FIG. 4, the protrusion 43b is formed to protrude from the side of the peeling part 43 in a substantially isosceles triangular cross section, and the height h of the cross-sectional shape of the protrusion 43b is selected to be an appropriate length depending on the thickness d of the slices 51. For example, when the food 50 is refrigerated meat and the thickness d of the sliced meat slices 51 is cut to about 2 mm, it is preferable to form the height h in the range of about 0.5 to 5.0 mm.

The gap t between the peeling portion 43 and the blade tip 22 is preferably at least about 0.1 to 0.5 mm so that the food 50 is cut and immediately peeled off from the inclined surface 23 of the blade tip 22 at the same time. The peeling portion 43 is preferably long enough to expose at least one edge portion of the circular blade 21 (particularly the inclined surface 23) when viewed from the front.

Next, the method for peeling the slices 51 of the food 50 from the round blade 21 using the above-mentioned configuration will be described with reference to Figures 5 and 6.

Figure 5 is a conceptual diagram of food 50 supplied from the supply unit 10 to the cutting position 12, with the round blade 21 of the cutting unit 20 making an incision. In this slicing device, after food 50 is supplied from the supply unit 10 to the cutting position 12, the round blade 21 rotated by the arm unit 24 cuts into the food 50 from an oblique upward direction, cutting it into slices 51 of a specified thickness d, and repeats the rotational motion (so-called revolution) in the direction of the arrow.

At this time, as shown in FIG. 6, the peeling means immediately peels the slices 51 from the cutting edge 22 of the round blade 21 by the peeling part 43 arranged approximately parallel to the side of the cutting edge 22 with a predetermined gap t. At this time, the inclined part 43a of the peeling part 43 is located on the same plane or approximately parallel to the inclined surface 23 of the cutting edge 22, so that the slices 51 can be peeled off without losing their shape. The slices 51 are then pushed out by the protrusion 43b of the peeling part 43, and are arranged from the peeling part 43 on the conveyor 31 of the discharge part 30 while retaining approximately the same shape as the cut surface of the food 50.

Therefore, by using a slicing device based on the above-mentioned configuration, the peeling means is not rotated at the same time as the circular blade 21 by fixing it at a distance from the rotating circular blade 21, and the slices 51 of the food 50 can be immediately peeled off without being dragged by the inclined portion 43a and the protrusion 43b in the peeling section 43. Furthermore, since the shape of the slices 51 of the food 50 can be arranged in the discharge section 30 in the same state as the cut surface of the food, there is no need to adjust the shape of the slices 51 when transferring them to a tray, making it possible to facilitate the transfer operation to the tray.

In addition, the peeling means is not formed integrally with the circular blade 21, and maintenance can be easily performed by replacing or cleaning only the peeling part 43.
