Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention extrudes a solid solution material that can maintain its original shape at room temperature, such as cream, which is a kind of food material, in a strip shape in a substantially horizontal direction from an extrusion port of a certain size. The present invention relates to an apparatus for continuously producing a rectangular material having a constant thickness by cutting this in a fixed amount in the middle.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional apparatus used to obtain such a material. The figure shows a device for the continuous production of cream as food material as a square material with a constant thickness. The material charged into the hopper 1 is pressure-fed to the extrusion device 3 through the switching type supply valve 2. As shown in FIG. 5, which is an enlarged view of the V portion of FIG. 3, the extrusion device 3 has a horizontal passage 4 having a rectangular cross section, and the passage 4 communicates with the outside world through an extrusion port 5 provided at one end. .

Reference numeral 8 denotes a cutter, which is formed in a flat plate shape along the vertical direction, is provided with a blade portion 9 having an inclined surface on one side, and is provided at a related position where the side surface of the extrusion port 5 is closed by descending. By the downward stroke of the cutter 8, the material m extruded in the horizontal direction from the extrusion port 5 is cut, and the cream 13 as a product having the shape shown in FIG. 4 is obtained. Cutter 8
Is operated by the cylinder 14 (FIG. 3) provided above. The cylinder 14 is fixed on the frame 15. Reference numeral 17 is a conveyor for conveying the cut cream 13. By regulating the operation interval of the cylinder 14, it is possible to cut the material for each fixed amount and automatically produce the flat-plate cream 13 of a predetermined size.

In addition, as a conventional device for cutting ordinary food materials, there is one that uses a wire as a cutter, for example. However, when cutting food materials with wires, if the food is solid and brittle, it can be easily cut,
In the case of the solid solution material that is the subject of this application, since the wire takes a short time to cut the material and pass through it, there is a strong possibility that the material will approach again from both sides and stick to it after passing through it. For the above materials, the use of wire cutters is not suitable.

[0005]

When the flat plate-shaped material is continuously produced by using the conventional apparatus shown in FIG. 3, the following problems may occur.

1) The process of cutting the material m by the cutter 8 will be described with reference to FIG.
After the cutter is cut, the cutter passes downward along the extension line of the operating direction,
Therefore, since the upstream cut end 20 of the material m corresponds to push-cutting in a state where the material m is supported by the peripheral wall of the passage 4 in the extrusion device 3 of the material m at the time of cutting, so-called sharp and clean. In contrast to the smooth surface, the downstream cut end 21a on the opposite side has a wide cutting surface that adheres to the blade portion 9 of the cutter 8 or its periphery at the same time as cutting, and is forcibly pushed and cut by the lowering of the cutter 8. The expression such as "it" is a suitable cut, the dimensional accuracy as a product is low, and the appearance is not uniform, resulting in poor product value. 2) Since the material m is a solid solution, the cream 13 having the shape shown in FIG. 4 travels downward due to the adhesiveness of the cut surface 21a which is a cut surface as a new surface generated by cutting, particularly the material surface. Conveyor 17
Various troubles are likely to occur due to the tackiness before getting on. That is, the cut end 21a faces downward and descends first to prevent regular landing on the conveyor surface, and as a result, the cream 13 is rolled into a dumpling, or the cut end 21a is turned upside down. It adheres to the lower surface of the extrusion device 3, and as a result, the finished state of the product is also damaged, resulting in a decrease in production efficiency.

The present invention has been made in view of the disadvantages of the above-mentioned conventional apparatus. By improving the operation mode of the cutter for cutting, the present invention can be applied to both the upstream side and the downstream side caused by cutting. Even if it is sharp,
An object of the present invention is to provide a material cutting device capable of forming a clean smooth surface.

Another object of the present invention is to provide a material cutting device capable of preventing damage to a product which is liable to be generated in a solid-soluble material until the cut material falls on a lower conveying device and is conveyed in an orderly manner. To do.

[0009]

As a means for solving the above problems, according to the solid solution material cutting device of the present invention, the bottom plate of the peripheral wall surrounding the extrusion port is placed outside the extrusion port. It is pushed out from the extrusion opening by the extension of the cutter receiving section and the relative position where the side surface of the extrusion opening can be closed by descending, and the final position of the stroke is restricted by the cutter receiving section. When the material is cut, a flat plate-shaped cutter having a thickness such that the contact between both surfaces of the end surface and the upper surface of the cutter receiving portion is a uniform surface contact, and the cut material is the cutter. In order to prevent the air from adhering to the surface on the side opposite to the extrusion port, an air blowing device for blowing air from the upper side to the lower side along the surface is provided.

When the solid solution material cutting device is constructed in this way, when the cutter descending the material extruded from the extrusion port cuts, the contact between the end surface of the cutter and the upper surface of the cutter receiving portion is made. Are arranged so as to be in surface contact in an even close contact state, the materials are placed in a state of being separated from each other by a distance corresponding to the thickness of the cutter by the surface contact, and the aspect of cutting on both sides is In both cases, since the lower surface corresponds to push-cutting in a state of being supported by the cutter receiving portion, so-called sharp and smooth surface can be formed on both surfaces. In addition, the shape of the cut surface is deformed in the direction that the surface area is reduced by push cutting, and the distance that the cutter relatively moves while contacting the material along the cut surface is a very short distance. Since the thickness of the material is limited by the cutter receiving part, the chance of sticking between the cut surface of the material and the surface of the cutter is extremely reduced, and as a result, the separation between the two is promoted. . Moreover, unlike the conventional device, the cut surface on one side is forcibly pressed and cut into pieces, and the product value is not deteriorated. Also, since an air blowing device that blows air downward from above is provided on the surface of the cutter on the side opposite to the extrusion port,
Cut material (product) is to viscous wear on the opposite side of the surface of the cutter to settle on the conveyor, the product value products is damaged become or becomes the product is "crumpled", or bunching There is no need to drop it, and work efficiency is greatly improved.

According to a second aspect of the present invention, as a means for preventing the material cut by the cutter from adhering to the lower surface of the cutter receiving portion or the material being caught in the solid solution material cutting device. Alternatively, an air blowing device for feeding air in a specific direction may be provided on the lower surface of the cutter receiving portion. With such a configuration, when the cut product is about to fall on the lower conveying device, the movement of the product is caused by the substantially horizontal air fed from the lower surface of the cutter receiving portion. Form into a state in which the cut end face is received on top of the wind, and at least immediately before the end of the operation of gently receiving the product on the conveyor running below, the end face cut to the other part. Since it will land on the conveyor ahead of time, it is possible to prevent the occurrence of problems similar to those that occur when the end surface adheres to the opposite side of the cutter, and when handling solid-soluble materials. It helps prevent damage to products that are likely to occur.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a solid solution material cutting device according to the present invention will be described with reference to the drawings. FIG. 1 and FIG. 2 are views showing different modes of operation for the same embodiment. The material put into the hopper 1 is sent to the extrusion device 3 via a repetitive switching type supply valve 2. The extruder 3 operates its built-in extrusion function to feed the material into the horizontal passage 4 having a rectangular cross section. The passage 4 communicates with the outside world through an extrusion port 5 provided at one end. The bottom surface of the peripheral wall surrounding the passage 4 and the extrusion port 5 is constituted by the bottom plate 6. The bottom plate 6 has its end portion extended to the outside of the extrusion port 5, and the cutter receiving portion 7 is provided at this portion.
Is composed.

The cutter 8 comprises a blade portion 9 and an air blowing device 10. The blade portion 9 is a portion involved in material cutting, and is provided at a related position where the side surface of the extrusion port 5 can be closed by descending, and the final position of the descending stroke is regulated by the cutter receiving portion 7. By the descending stroke of the cutter 8, the material m extruded from the extrusion port 5 by a predetermined length is cut. 11
Is a blower pipe for feeding air to the air blowing device 10,
The sent air passes through the air passage 12 and the ejection port 5 of the blade portion 9.
And the cream 13 which has been blown out along the surface 9a on the opposite side to the material m or has already been cut into a product
However, this is especially for preventing the cut edge and the like from adhering to the surface 9a of the blade portion. The operation of the cutter 8 is
It is performed by the cylinder 14 provided above. The cylinder 14 is fixed on the frame 15. A cutter 16 is provided to blow air around the lower surface of the cream 13 immediately after cutting in order to prevent the cream 13 that has been cut into a product from adhering to or being caught in the lower surface of the cutter receiving portion 7. It is an air blowing device provided on the lower surface of the receiving portion 7.
Reference numeral 17 is a conveyor for conveying the cream 13 that has been cut into a product.

In FIG. 2, the end surface 18 of the cutter 9 having the blade portion 9 is a surface contact in a state where the bottom plate 6 and the upper surface 19 of the cutter receiving portion 7 of the extension thereof are in a uniform contact state. It is formed on the thickness. Therefore, the blade 9
Is lowered and the end face 18 lies on the cutter receiving portion 7 m
Are pressed from above, and the materials m are separated from each other on the feed line by a dimension corresponding to the thickness of the end face 18. The upstream cutting edge 20 and the downstream cutting edge 21 of the separated material m are both cut off in a form in which the material m is placed on the upper surface 19 of the cutter receiving portion 7 at the time of cutting. It has a clean and smooth surface. Further, the shape of the cut surface is deformed in the direction in which the surface area of the cut surface 21 on the downstream side is reduced by the push cutting as shown in the drawing. Furthermore, the distance that the cutter moves relative to the material along the cutting surface while moving relative to the material is a very short distance, and the distance is limited by the cutter receiving part so that it does not exceed the thickness of the material. However, the chance of adhesion between the cut surface of the material and the surface of the cutter is extremely reduced, and as a result, the separation between the two is promoted. Moreover, due to this cutting mode, the dimensional accuracy as a product is improved, and a finished product excellent in appearance can be obtained.

Next, the mode of operation of the solid solution material cutting device according to the present invention will be described. The raw material of cream is put into the hopper 1 and stirred, and this is pressure-fed to the extrusion device 3 by operating the switching type supply valve 2. The material m introduced into the passage 4 of the extrusion device 3 is horizontally guided under a predetermined extrusion capacity and is pushed out of the passage through the extrusion port 5 while the lower surface is supported by the bottom plate 6. The cutter 8 carries out a descending step for cutting in accordance with an operation interval regulated by the cylinder 14, and as a result, cuts the material m in a fixed amount, and automatically produces a flat cream 13 of a predetermined size. To do. In addition, the cut cream 1 is cut by blowing air from the blower pipe 11 to the air blowing device 10 and blowing the air to the surface 9a on the opposite side of the blade portion 9 at the timing of the descending step.
The cut end 21 of No. 3 and the like prevent the occurrence of troubles by attaching to the surface 9a.

Further, as shown in FIG. 2, the cream 1 is provided by the air blowing device 16 provided on the lower surface of the cutter receiving portion 7.
By sending air around the lower surface of 3, the cream 13 that is about to fall onto the conveyor 17 as a product
Becomes a shape riding on the substantially horizontal air fed from the lower surface of the cutter receiving portion 7, and the end surface of the cut end 21 is received on the wind and travels downward. In the operation of gently receiving the product on the conveyor 17, at least the cut end 21 cut immediately before is landed on the conveyor 17 in advance of other portions, and the end surface is opposite to the cutter 8. It is possible to prevent the occurrence of trouble similar to that which occurs when the material 9a is attached to the lower surface of the cutter 9a. Can be prevented in advance.

[0017]

As is apparent from the above description,
According to the solid solution material cutting device of the present invention, (1) In claim 1, by improving the shape of the cutter for cutting and the operation mode of the cutter, the upstream / downstream side of the cutting A clean smooth surface with excellent sharpness can be formed on both end surfaces.

(In the case of the conventional apparatus, the cut 20 on the upstream side of the material m is in a state in which the material m is supported by the peripheral wall of the passage 4 in the extrusion apparatus 3 for the material m at the time of cutting, as shown in FIG. Since it corresponds to the push-cutting on the surface, it becomes a so-called sharp and clean smooth surface, but the downstream cut 2 on the opposite side.
At the same time, the large cutting surface of 1a adheres to the blade portion 9 of the cutter 8 or the periphery thereof at the same time as cutting, and the expression that the cutter 8 is forcibly pressed and cut by the lowering of the cutter 8 is a suitable cut end, so that the dimensional accuracy as a product is also high. It was low in quality and uneven in appearance, resulting in poor product value. ) In addition, it is possible to improve production efficiency by using air to prevent the product from being damaged by its self-adhesiveness.

(2) According to the second aspect of the present invention, the damage of the product, which is likely to occur in the solid-soluble material until the cut material falls as a product on the lower conveying device and is conveyed in an orderly manner, is extensive. Can be prevented.

(In the case of the conventional device, the cream 13 having the shape shown in FIG. 4 runs downward due to the adhesiveness of the material surface, particularly the cut surface 21a (FIG. 6) which is a new surface generated by cutting. Various troubles due to stickiness are likely to occur before getting on the conveyor 17. That is, the cut edge 21a faces downward and descends first to prevent normal landing on the conveyor surface. Cream 1
3 is rolled into a dumpling, or cut 2
1a flips upward and adheres to the lower surface of the extrusion device 3, and as a result, the finished state of the product is also damaged, which tends to cause a problem such as a decrease in production efficiency. )
