Abstract

PURPOSE:To increase the vertical movement speed of a cutter and to improve the efficiency of cutting of a food by laterally juxtaposing two crank shafts and fixing the cutter to each crank arm, having a base end to which a balancing weight is attached, through a mounting plate. CONSTITUTION:Food F is placed respectively on the right and left halves of a food moving surface 2 and when a food feed switch is turned ON, a food feed member 23 is moved forward and the food F is moved forward with a press by means of a push-in plate 24. When the food F is moved to the lower position of a press roller, the press roller is lowered and the food F is pressed. Thereafter, when a food cut switch is turned ON, crock shafts 3 laterally juxtaposed is rotated through a toothed belt transmission mechanism 11 with the aid of an electric motor. Each crank arm 4 with a balancing weight 8 is rotated in the same direction in synchronism with rotation of the crank shaft and the mounting plate 5 and a cutter 7 are rotated in a state to hold a laterally long posture and vertically moved. Since the two foods F are moved forward by a distance, equivalent to a cut thickness, in synchronism therewith, the food F is cut to constant widths.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food slicer for cutting food such as frozen meat with a vertically movable blade.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6, a food slicer of this type is provided horizontally with a food moving surface 51 on which a food F such as frozen meat slides and advances. A driven gear 5 in which two gear shafts 52 are laterally arranged side by side in the front and rear direction at the upper side of the forward end and fixed to the ends of both gear shafts 52
3 are arranged in the same vertical plane.

In the peripheral portion of the left and right driven gears 53, as shown in FIG.
6, the horizontally extending rectangular mounting plates 54 are attached to both driven gears 53 by bearing the pins 55 protruding in parallel to the left and right on the mounting plate 54, and the horizontally long rectangular mounting plates 54 are attached to the lower portions of the mounting plates 54. A rectangular blade 56 is fixed vertically.

The upper position of both gear shafts 52 is shown in FIGS.
2, the drive shaft 57 is supported in the front-rear direction, and the drive gear 58 fixed to the end of the drive shaft 57 is attached to both driven gears 53.
To the electric motor 5 at the other end of the drive shaft 57.
Nine rotation shafts are connected.

When the electric motor 59 is driven, the drive shaft 57 and the drive gear 58 rotate, and as shown in FIG. 6, both driven gears 53 synchronously rotate in the same direction, so that the mounting plate 54 and the cutting tool 5 are rotated.
6 rotates vertically while maintaining a horizontally long posture and moves up and down. When the blade 56 reaches the descending end, the blade at the lower end moves to the food moving surface 5
When it comes into contact with No. 1 and reaches the rising end, a gap wider than the height of the food F is formed between the blade at the lower end and the food moving surface 51.

At the lower side of the food moving surface 51, as shown in FIGS. 5 and 6, a screw shaft 60 is supported in the front-rear direction, and the screw shaft 60 is provided with a screw hole in the lower portion of the food supply member 61. An elongated hole 62 formed through the food moving surface 51 in the front-rear direction penetrates the central portion of the food supplying member 61, and the upper portion of the food supplying member 61 projects above the food moving surface 51. 63 rotation shafts are connected.

When the electric motor 63 is driven, the screw shaft 60 rotates and the food supply member 61 moves the blade 5 as shown in FIG.
6, the food F placed on the food moving surface 51 is pushed by the upper portion of the food supply member 61 and moves forward.

When the food slicer is operated, as shown schematically in FIG. 5, the food F on the food moving surface 51 advances toward the blade 56, and the blade 56 moves up and down, so that the front end of the food F becomes thinner in sequence. Be disconnected.

[0009]

However, in the above food slicer, if the vertical movement speed of the blade 56 is increased in order to increase the cutting efficiency of the food F, the blade 56 vibrates and the food F is smoothly moved. Will not be cut off. The cause is as follows according to the research by the present inventor. Since both driven gears 53 have the mounting plate 54 and the blade 56 attached to their peripheral portions, they are extremely unbalanced as a rotating body. In addition, the driving gear 58 and the driven gears 53 meshing with the driving gears 58 have worn tooth surfaces due to their use, and cannot rotate smoothly, impairing the synchronism of rotation of both driven gears 53.

Further, in the above food slicer, the operation of placing the next food on the food moving surface 51 after the food F on the food moving surface 51 has been cut and the food supply member 61 has retracted is large. It takes time because the worker places heavy food by hand. Therefore, it takes a long time to finish cutting the previous food and start cutting the next food.

As a result, the above food slicer does not have a high food cutting efficiency.

An object of the present invention is to solve the above conventional problems.

[0013]

DISCLOSURE OF THE INVENTION The present invention is a food slicer in which a food on a food moving surface advances toward a cutting tool, the cutting tool moves up and down, and the front end of the food is sequentially cut.
