Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food slicer for slicing a food product such as a lump of meat with an endless band-shaped blade.

[0002]

2. Description of the Related Art In this type of food slicer, a drive pulley and a driven pulley are provided on the left and right sides, and endless belt-shaped blades are bridged over both pulleys, and as shown in FIG. The receiving plate 52 is provided horizontally, the upper part of the blade 51 is inserted into the insertion groove of the front end of the receiving plate 52, the blade edge of the upper part of the blade 51 is projected above the front side of the receiving plate 52, and the upper part of the blade 51 A cutting thickness adjustment plate is provided on the front side so that the vertical position can be adjusted,
A food insert cylinder 54 having a quadrangular cross section is vertically arranged above the blade 51, and the upper end of the food insert cylinder 54 is supported by a shaft 55 so that the lower end of the food insert cylinder 54 can be rocked back and forth.
An oscillating device (not shown) is connected to 4.

When slicing a food product such as a lump of meat, FIG.
As shown in, the cutting thickness adjusting plate 53 is arranged below the cutting edge of the upper part of the blade 51 according to the cutting thickness, and the food F is inserted into the food insertion cylinder 54 from the upper end opening thereof. The lower end projects from the lower end opening of the food insertion cylinder 54 and is placed on the upper edge of the blade 51 and the receiving plate 52, and the drive pulley is rotationally driven to move the blade 51 in one direction.
Rock back and forth.

When the food insertion cylinder 54 swings to the front side, the food F in the food insertion cylinder 54 moves up and down a little, and the lower end of the food F moves from above the cutting edge of the upper part of the cutter 51 to the cutting thickness adjusting plate 53. When the food insertion cylinder 54 is placed on the top and swings rearward, the lower end of the food F in the food insertion cylinder 54 is cut at the upper side of the running blade 51 as shown by the broken line in FIG. The section f falls from between the upper side of the blade 51 and the cutting thickness adjusting plate 53.

[0005]

However, in the above food slicer, if the food F is thicker than the food insertion tube 54, the food F cannot be inserted into the food insertion tube 54 and the food F is cut. Can not do it. If the food F is considerably thinner than the food insertion cylinder 54, a wide gap is formed between the food insertion cylinder 54 and the food F contained therein, and the food F is not held in the food insertion cylinder 54 when the food F is cut. The food F moves back and forth and left and right in the food insertion cylinder 54, and the food slice f does not have a uniform thickness.

As shown in FIG. 10, between the lower end opening of the food insertion cylinder 54 and the cut portion of the food F when the food insertion cylinder 54 is swung forward and tilted and when it is vertical. The vertical distance D of the food F is different, and the length of the cut portion of the food F protruding from the lower end opening of the food insertion cylinder 54 during the cutting of the food F is D.
Fluctuates, the amount of deformation of the cut portion of the food F due to cutting resistance changes, and the slice f of the food does not have a uniform thickness.

As a result, the range of cross-sectional dimensions of the food F that can be cut is narrow, and the slice f of the food has an uneven thickness.

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

[0009]

According to the present invention, a reciprocating member is provided so as to be horizontally movable in the front-rear direction, a drive pulley and a driven pulley are attached to the reciprocating member at left and right positions, and endless belt-shaped blades are hung on both pulleys.
