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 soft food.

[0002]

2. Description of the Related Art A food slicer of this type is disclosed in Japanese Patent Laid-Open No. 4-6.
As disclosed in Japanese Patent No. 9193 as a first embodiment, a conveyor device that supplies food by cutting thickness is provided, and an endless band-shaped blade that rotates in one direction crosses an upper position of the conveyor device. Along with, a knife lifting device for lowering the belt-shaped blade every time the food on the conveyor device is supplied by the cutting thickness is provided, and the tip of the food on the conveyor device is moved every time the belt-shaped blade is lowered. Cut at the lower part of the band-shaped blade.

However, in a food slicer in which a knife moves in one direction, soft foods such as meat and fish are easily deformed and sticky.
The cutting surface is pulled in the moving direction of the blade, and the cutting tip of the food and the food slice are deformed. Therefore, the food is not cut into a uniform thickness, and the slices have uneven thickness. Also, the section is
It becomes deformed or curved, making it difficult to arrange.

Therefore, a food slicer was invented in which the belt-shaped knife reciprocates in the longitudinal direction at a low speed while reciprocating largely at a high speed while the knife cuts the food, and as a Japanese Patent Application No. 5-329511. Applied for a patent.
In this food slicer, since the cutting surface of the food being cut is not pulled in one direction, the cutting tip and the slice are not easily deformed even if they are soft.

[0005]

However, in the above-mentioned food slicer in which the strip-shaped blade reciprocates at a high speed and small at a high speed, the device for reciprocating the strip-shaped blade at a high speed supplies a high-pressure air. , An air cylinder mechanism is used in which the piston moves forward and the air path is switched for backward movement, the piston moves backward and the air path is switched for forward movement, and the piston repeats forward and backward movements.

In this high speed small stroke reciprocating drive device of the air cylinder mechanism, it is difficult to control the speed of the band-shaped blade and the number of reciprocations per unit time, which are related to the sharpness of the food. Further, the speed of the strip-shaped blade and the number of reciprocations per unit time largely vary depending on the load of the strip-shaped blade. When the load of the band-shaped blade increases, the speed of the band-shaped blade decreases, the number of reciprocations per unit time decreases, and the cutting efficiency greatly decreases.

Therefore, in the above food slicer,
The range in which soft food can be cut with high efficiency without deforming the cutting tip and the section is not wide.

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

DISCLOSURE OF THE INVENTION The present invention provides a conveyor device for feeding food by cutting thickness, and a belt-like blade is provided along a direction crossing the upper position of the conveyor device. In a food slicer that installs a knife lifting device that lowers the strip-shaped knife every time it is supplied by the cutting thickness, and cuts the tip of the food on the conveyor device with the strip-shaped knife every time the strip-shaped knife descends In the meantime, a low speed large stroke reciprocating drive unit and a high speed small stroke reciprocating drive unit are provided to reciprocate the belt-shaped blade in the longitudinal direction at a low speed while reciprocating at a high speed and a small reciprocating motion at a high speed. In addition to attaching a prime mover to the shaft that rotates by the drive of the electric motor, a follower is attached to the belt-shaped blade, the drive element contacts the follower, and the blade is reciprocated by the drive of the electric motor. Using the cam mechanism to the dynamic, providing a tool groove strip cutter inserts reaching lowering end, cutlery
Insert a scraping plate into the groove, and remove the scraps every time the strip-shaped blade rises.
Raise the cutting plate and project the upper end of the cutting plate above the blade groove
A lifting plate lifting device was installed .

[0010] In addition, in this food slicer, strip
The strip stripping plate that moves up and down together with the blade is a strip-shaped blade at its lower end.
It is provided by superimposing on the front of the object and every time the strip-shaped blade reaches the descending end.
Was equipped with a tilting device for tilting the section stripping plate to the front side .

[0011] In addition, in the food slicer of this, sections
While the stripper is descending and tilting, in front of the section stripper
A spray device for spraying the fluid obliquely downward was provided on the surface.

[0012]

In the food slicer of the present invention, while the band-shaped blade cuts the food, the band-shaped blade reciprocates at a low speed in the longitudinal direction thereof while reciprocating at a high speed, so that the food being cut is The cut surface cannot be pulled in one direction. Even if the food is soft, the cutting tip and the section are not easily deformed. It is difficult for the sections to have uneven thickness. In addition, the sections are unlikely to have a shape that is difficult to arrange.

Further, in the high speed small stroke reciprocating drive device, when the rotational speed of the shaft rotated by the driving of the electric motor is controlled, the speed of the belt-shaped blade and the reciprocating speed per unit time related to the sharpness of the food are controlled. . Further, when an electric motor having a constant speed characteristic is used, the speed of the blade and the number of reciprocations per unit time do not change depending on the load of the blade. Even if the load of the band-shaped blade increases, the speed of the band-shaped blade and the number of reciprocations per unit time do not decrease, and the cutting efficiency does not decrease.

[0014]

INDUSTRIAL APPLICABILITY According to the present invention, there is a wide range in which soft food can be cut with high efficiency without deforming the cutting tip and the section.

Pushed out of 3. When the dust removing plate 34 reaches the rising end, the dust removing plate elevating device 35 is lowered to lower the dust removing plate 34.

When the residue removing plate 34 is restored to its original position as shown in FIG. 1, the feed conveyor device 1 is driven again to feed the food F on the cutting thickness by the cutting thickness, and the front end of the food F is the same as the previous one. Similarly, the piece f that is cut and placed on the rear part of the take-out conveyor device 32 falls to the front side as shown by the chain line in FIG. 8, and the front part is stacked on the rear part of the piece f that was cut last time.

Each time a predetermined number of pieces of section f are placed on the take-out conveyor apparatus 32, the take-out conveyor apparatus 32 is driven at a high speed for a predetermined distance, and a predetermined number of pieces of section f, which are partially stacked, are sent to the front side. Note that this predetermined number of slices f
Are packaged in trays with some of them stacked.

A specific example of the operating condition of the food slicer is that the number of times the strip-shaped blade 15 is moved up and down, that is, the number of times the food F is cut is 10 per minute.
40 times, the low speed large stroke reciprocating motion of the belt-shaped blade 15 is about 30 to 60 times per minute and the stroke is about 50 mm, and the high speed small stroke reciprocating motion of the belt-shaped blade 15 is from 10,000 to minute.
About 5,000 times, the stroke is about 5 to 10 mm.
