Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cutting device mainly used for cutting geeks, breads, processed meat products, and seaweed sushi rolls.

[Conventional technology]

Conventionally, cakes, breads, etc. have been cut using circular saws, band saws, or mechanical reciprocating devices as seen in Japanese Patent Publication No. 56-28678.

[Problem that the invention seeks to solve]

However, when using the former circular saw or band saw, a lot of chips are generated and the cutting life of the cutting edge is short.
It required frequent polishing. The latter mechanical reciprocating type usually uses a frame with multiple blades stretched in parallel to reciprocate, and the magnitude of the amplitude and amplitude frequency is determined by the drive capacity of the device and energy cost. tends to be inversely proportional, so I try to select and set the amplitude and frequency that match the object to be cut. However, ordinary objects to be cut are not made of uniform materials, but are more commonly made of composite materials, such as cakes made of castella cake and cream, or meat products made of fleshy and fibrous parts. In such cases, the amplitude and frequency set for one material are unlikely to be suitable for the other material. For example, in the case of a cake, when cutting the sponge cake part, a higher frequency has higher cutting efficiency and a smoother cut surface, but since the amplitude is small, the adhesion position of the cream does not change, and as the object to be cut moves relative to each other, The cream on the surface may accumulate and form a lump. This also applies to items that partially contain fiber, such as meat and seaweed.

In addition, when the amplitude is small at high frequencies, the positions where the blade can be used are limited, resulting in locally reduced sharpness, increased frequency of replacement for polishing, and reduced operating efficiency. .

[Means to solve the problem]

The present invention includes a blade frame including a plurality of blades arranged in parallel at required intervals in the thickness direction of the blades, and a workpiece to be cut that is moved in a direction perpendicular to the thickness direction of the blades and intersecting the blades. a plurality of movable inner frames to which the blade frames are removably attached; a plurality of movable outer frames to which the movable inner frames are swingably attached in the length direction of the blade; a fixed frame that supports the outer frame so as to be swingable in the length direction of the blade with the outer frame being shifted back and forth in the moving direction of the object to be cut and in the thickness direction of the blade; a vibrating device that vibrates the frame in the length direction of the blade relative to the movable outer frame; and a vibrating device that is provided on the fixed frame and vibrates the movable outer frame in the length direction of the blade with a larger vibration amplitude and lower frequency than the vibrating device. The above-mentioned conventional problems are solved by providing a swinging device for swinging. Note that the vibration device is swung by a rocking device, and it is desirable to have a lightweight and simple configuration.For this purpose, the movable inner frame is attached to the movable outer frame via an elastic member such as a spring, and an electromagnet is driven. The structure is based on the source.

[Effect]

When the rocking device and the vibrating device are operated, each movable outer frame swings at a low speed in a relatively large width with a phase shift from each other, swinging the blade together with the movable inner frame, and causing the movable inner frame to swing at low speed. The frame vibrates at a high speed with a relatively small width superimposed on the swinging of the movable outer frame, thereby vibrating the blade.

In the above operating state, when an object to be cut, such as a cake, is fed into the cutting surface of the blade, the object to be cut is efficiently cut with a smooth and clean cut due to the oscillating motion of the blade accompanied by high-speed micro-vibration.

That is, the castella part is cut smoothly and efficiently by the high-speed micro-vibration, and the rocking with a larger stroke causes the cream to adhere to the blade at different positions, thereby preventing the cream from accumulating into lumps. If the base is made of a material that partially contains fibers, high frequency and small amplitude vibrations are suitable for cutting the base, and lower frequency and large amplitude vibrations are suitable for cutting the fibers. . and,
The swinging allows the blade to be used over a wider range, allowing longer blades to be attached and used, increasing the polishing interval and increasing operating efficiency.

are arranged alternately.

The lower attachment part 30 fixes the lower parts of the blades 29a and 29b, and the blades 29a and 29b are attached to the tips thereof.
A slit 32 is formed to insert the blade 29b, and a recess 34 is formed to lock a tension boss 33 attached to the lower end of the blades 29a, 29b on the lower surface. The upper mounting part 31 has a blade 29a,

A hole 38 is formed into which a U-shaped spring member 37 is inserted, which acts on a tension boss 36 attached to the upper end of the blade 29b to straighten the blades 29a, 29b.

In FIG. 13, 40 is a feed conveyor that feeds the object to be cut, such as a cake, to the cutting surface of the blades 29a, 29b, and 41 is a conveyor that feeds the object to be cut, such as a cake, to the cutting surface of the blades 29a, 29b.
This is a take-out conveyor that takes out the cut object to the outside. The feed conveyor 40 is formed narrowly, and its tip protrudes from between the blades 29a and 29b toward the take-out conveyor 41 side.

Next, a method of using the device for cutting cakes, etc. according to the present invention constructed as described above will be explained along with its operation.

First, the blades 29a, 29 are mounted on the blade stands 24a, 24b attached to the frames 22a, 22b.
Attach b. In this case, the blades 29a, 29
b into the slits 32, 35 of the mounting parts 30, 31 and pull it upward, the lower tension boss 33 is locked in the recess 34 of the lower mounting part 30, and the spring is inserted between the upper tension boss 36 and the fitting hole 38. The member 37 is bent and fitted. By this operation, the blades 29a, 29b are fixed to the blade stands 24a, 24b in a tensioned state in the longitudinal direction.

After the blades 29a, 29b are attached to the blade stands 24a, 24b in this way, the blade frames 14a, 14b are attached to the blades 29a, 29b.
The length direction of the movable outer frames 5a, 5b and the vibration direction of the movable inner frames 13a, 13b are fitted into the movable inner frames 13a, 13b so that the length direction of the movable outer frames 5a, 5b matches the vibration direction of the movable inner frames 13a, 13b.
7 and bolts 28. Movable inner frame 13
When fitting the blade frames 14a, 14b into the movable inner frames 13a, 13b, the inclined outer surfaces of the wedge members 25 of the blade frames 14a, 14b align with the movable inner frames 13a, 13b.
Since the blade frames 14a and 14b are properly and firmly attached to the movable inner frames 13a and 13b, the blade frames 14a and 14b can be properly and firmly attached to the movable inner frames 13a and 13b.

After the above preparations are completed, the swing device 6 and the vibration devices 18a and 18b are operated. Due to the operation of the swinging device 6, the two movable outer frames 5a, 5b swing up and down with their phases shifted by 180 degrees, and the movable inner frames 13a, 13b
At the same time, the blades 29a and 29b are oscillated up and down with a large oscillation width and at a low frequency. In addition, the two movable inner frames 13 are activated by the vibration devices 18a and 18b.
a, 13b vibrate up and down, blades 29a, 2
9b is superimposed on the above-mentioned vibration to vibrate at a high frequency with a small vibration width.

In this state, the conveyors 40, 41 are operated, and the object to be cut, such as a cake, is transferred to the blades 29a, 29.
Insert into part 9b. Blades 29a, 29b
In this case, the blades 29a and 29b are oscillating along their lengths and cut the object smoothly and sharply. Therefore, generation of chips is suppressed as much as possible. Also, when some blades descend to cut the object, other blades adjacent to it rise to cut the object, so the object is always cut almost evenly from top to bottom. Force is applied, and the object to be cut is prevented from following the blade, which would reduce the sharpness of the blade, resulting in better cutting.

The amplitude and frequency of the vibration devices 18a and 18b can be adjusted by turning the spring adjustment bolts 15a and 15b.
The position of the electromagnet 19 required to change the elasticity of the springs 16a, 16b and maintain a balanced relationship between the elasticity and the attractive force of the electromagnet 19 (
0) can be adjusted by adjusting the threaded rod 19a and nut 19b.

The blade frames 14a and 14b can be moved to the movable inner frame 13 by changing the cutting width, replacing the blade, cleaning, etc.
If it becomes necessary to remove it from a, 13b,
Loosen the bolts 28 and remove the blade frames 14a, 14b.
However, in this case, as described above, the blade frames 14a, 14b are attached to the movable inner frames 13a, 13b by bringing the slopes of the wedge members 25 into contact with the slopes of the receiving members 26 of the movable inner frames 13a, 13b. It can be easily and quickly removed since it is simply inserted into the holder. Therefore, accompanying operations such as replacement and cleaning are easy to perform, cutting operations can be carried out efficiently overall, and the apparatus can be easily managed in a sanitary manner.

〔Effect of the invention〕

As explained above, the device for cutting cakes, etc. of the present invention vibrates the blade in its length direction while moving the object to be cut across the blade, and also vibrates at a frequency lower than that of the blade. The structure is such that it cuts objects such as cakes by swinging with the amplitude, so the two types of vibrations produce good cutting performance and high efficiency, depending on the characteristics of the composite material contained in the object. Moreover, it is possible to perform cutting with a smooth cut surface. In addition, the blade is vibrated to move the object at high speed to increase cutting efficiency, while the blade is oscillated to widen the range of use of the blade to prevent chips, cream, etc. from adhering to the blade. This has excellent effects such as slowing down the deterioration of blade sharpness and reducing the frequency of replacement work such as polishing, which improves the operating rate of the equipment. It is something that plays. In addition, by configuring the vibrating device that is to be swung by the oscillating device using an electromagnet as a driving source,
