Description

Detailed description of the invention

TECHNICAL FIELD The present invention relates to a method and an apparatus for automatically forming a bean paste product by automatically squeezing bean paste made of chestnuts, potatoes, or the like.

Japanese confectionery made by squeezing an bean paste made from chestnuts, potatoes, etc. into tea towels is widely known, and the demand for chestnut kinton is particularly high.

Conventionally, traditional Japanese sweets made by squeezing bean paste made from chestnuts, potatoes, etc. with a tea cloth are hand-made one by one by craftsmen. Because it is handmade, the number of products produced is limited, and popular products often cannot meet demand.

Various attempts have been made to automate the process so that mass production can be achieved. Handcrafted by craftsmen, each one has a slightly different shape and looks great as a Japanese confectionery.

For example, Japanese Patent Publication No. 4-19830 discloses an apparatus for forming a wrinkled pattern on the top of a food like chestnut kinton, which is a Japanese confectionery. (Patent Document 1)
This device automatically forms twisted folds in the skin of Chinese steamed buns. Three or more vertically movable fingers 1, 1 having outer claws 2, 2' at their respective ends and a pulley 6 at the upper end, equidistantly around a vertically movable outer shaft 3 with a built-in 3'. ' is pivotally mounted at fulcrums 8 and 9, and vertical movement of the fingers also performs opening and closing of the fingers by a tapered guide 5, a guide groove 7 provided in the guide, a pulley sliding in the groove, and a fulcrum. It is a device for twisting and pleating steamed buns, which is a configuration.

Japanese Unexamined Patent Application Publication No. 6-181734 discloses a method for producing confectionery and other foods as a technique for forming bean paste products using a mold and a sheet. (Patent Document 2)
This technology is a method of automatically forming plastic objects such as such. While the food is pushed downward while the material is attached, the sheet material attached to the food is peeled off from the surface of the food sequentially during this extrusion.
``It is characterized by blowing high-pressure gas from the back surface of the mold to separate the sheet material from the molding part and push the food downward while the sheet material is still attached.''

Japanese Patent Publication No. 4-19830 JP-A-6-181734

In the "twist pleating device" described in Patent Document 1, "twist pleats" are formed on the head and shoulders of Chinese buns conveyed by a belt conveyor, but from chestnuts and potatoes (sweet potatoes etc.) Since the bean paste is softer than the Chinese manju and easily loses its shape, if force is applied to the bean paste to create a "twist fold" with the above device, the shape of the bean paste will be lost and the appearance as a Japanese sweet will be lacking. .

In the "Method for Molding Confectionery and Other Foods" described in Patent Document 2, the sheet material corresponding to the brown cloth is flat, and is not configured in a specific shape. Therefore, the outer surface of the food product pressed against this sheet material does not have the peculiar irregularities such as brown cloth squeezed, and lacks in appearance.

An object of the present invention is to simultaneously form the bean paste and form the pleated pattern, and to provide a beautifully shaped bean paste product which does not lose its shape.

In the method and apparatus for automatically forming bean paste made of chestnuts, potatoes, etc., according to the present invention, a predetermined amount of lumps of bean paste material is conveyed to the bottom of a mold by a conveyor, and a recessed space is formed in the bottom surface of the mold. The mass of the bean paste material is press-fitted into an upper mold with a brown cloth inside to form a bean paste product.
A brown cloth insertion hole is provided at the top of the empty room, and the brown cloth is inserted into the hole by narrowing the central part of the brown cloth, and further along the inner surface of the empty room, from the central part of the brown cloth toward the peripheral edge. By providing a plurality of rows of folding folds in which mountain folds and valley folds are combined radially, and pressing these folding folds against the top of the bean paste material, a pleat pattern similar to the pleat pattern hand-made by craftsmen is formed from the head of the bean paste. Formed over the shoulder.
The folding folds of the brown cloth are arranged in a plurality of radial rows of mountain folds and valley folds when attached to the upper mold.

The molded bean jam is discharged by compressed air jetted from the empty chamber. Alcohol is also injected at that time. Empty rooms, tea cloths, and bean paste products are disinfected at the same time by spraying alcohol. A time difference may be provided between the injection of compressed air and the injection of alcohol.

A through hole is provided in the upper die so as to cut out a part of the inner peripheral surface of the empty chamber, a tube having one end closed is inserted through the through hole, and compressed air is injected into this tube. When compressed air is injected into the tube, the tube expands and protrudes into the empty chamber through a notch formed in the empty chamber, and the top and shoulder portions of the bean paste in the empty chamber are deformed by the bulge of the tube.

A method for automatically forming a bean paste product by forming a plurality of rows of folded pleats combined with each other radially, and press-fitting the bean paste material into the vacancies to form a fold pleat pattern on the surface of the bean paste material.

Since the brown cloth forms folds when it is attached to the upper die, it can be individually formed into different folds. Therefore, it is possible to produce bean paste products with arbitrary folding pleat patterns for each upper mold. It is possible to provide bean paste products with a large number of folds and a few bean paste products.

The invention according to claim 2,
2. The method for automatically forming a bean paste product according to claim 1, wherein when the compressed air is injected after the molding is completed, alcohol is sprayed into the empty space from a plurality of positions in the passage to disinfect the empty space, tea towels and bean paste with alcohol. be.

By injecting alcohol into the vacant chamber from a passage provided in the upper mold, the vacant chamber, tea towels, and bean paste products are disinfected at the same time.
Since the alcohol enters between the brown cloth and the bean jam product through the exposed openings of the tea cloth, the separation of the brown cloth and the bean jam product is facilitated. If the brown cloth and the bean paste product can be separated quickly, the molding speed can be increased.

The invention according to claim 3,

A brown cloth is provided, the bean paste material is placed under the upper mold, and the bean paste material is pressed into the cavity of the upper mold to form the bean paste, and after molding is completed, compressed air is injected into the cavity from the passage. In the automatic molding equipment for bean paste products that discharges the bean paste from the empty chamber,
A brown cloth insertion hole leading to the empty chamber is provided in the center of the upper die, the central portion of the brown cloth is narrowed and inserted into the brown cloth insertion hole, and the brown cloth arranged in the empty chamber is spread to perform mountain folds and valley folds. This is an automatic forming apparatus for bean paste products, in which a plurality of rows of combined folding folds are formed radially.

Since the brown cloth has creases formed when it is attached to the upper die, it can be individually formed into different crease shapes. Therefore, it is possible to produce bean paste products with arbitrary folding pleat patterns for each upper mold. It is possible to provide bean paste products with a large number of folds and a few bean paste products.

The invention according to claim 5,
Some of the passageways provided in the upper mold are automatic molding devices for the bean paste products that are connected to an alcohol supply.

By spraying alcohol into the empty room, the empty room, tea towels, and bean paste products are disinfected at the same time. As a result, the operator does not need to spray alcohol to disinfect the mold after each molding, and an improvement in the molding speed can be expected.

The invention according to claim 6,
A through hole is provided horizontally or obliquely on the side of the empty chamber by cutting out a part of the inner peripheral surface of the empty chamber, and a highly flexible tube that can be expanded by injecting compressed air is inserted into the through hole, 5. The bean paste according to claim 4, wherein one end of the tube is closed and compressed air can be injected from the other end, and the injection of the compressed air expands a part of the tube so that it protrudes into the empty chamber. This is an automatic molding device for products.

When compressed air is injected into the tube, the outer peripheral surface of the tube expands due to the pressure of the compressed air at the notch hole portion of the empty chamber, protrudes toward the inside of the empty chamber, and slightly deforms the top or shoulder of the bean paste material. Let By changing the degree of protrusion of the tube each time, a wide variety of bean paste products with different shapes each time can be provided.

According to the present invention, by forming folds on the tea cloth, it is possible to efficiently mass-produce bean paste products having folds similar to those of hand-made products by craftsmen, and to meet many demands.
Since the brown cloth is attached along the inner surface of the air space and the apex thereof is fixed inside the air space, the brown cloth does not protrude out of the air space when the compressed air is injected, and the brown cloth is exposed to the outside. It is easy to blow off the jam material clogged in the container, and it is difficult to cause clogging even after continuous use.
Since the shape, number, width, etc. of the folds can be determined each time the tea cloth is attached to the upper die, it is possible to deal with small lots. Even if the same cloth is used for operation, it is possible to change to a different pleat pattern only by shifting the folding pleats without removing the upper mold after temporarily stopping the operation. Since the folding folds are not fixed, it can be handled.

In addition, after the completion of molding, the upper mold, tea towels, and the bean paste product can be disinfected at the same time by injecting alcohol when ejecting the bean paste product from the upper mold by blowing compressed air. The molding speed can be expected to improve compared to the conventional method in which the operator sprays alcohol on each molding to disinfect it.

When compressed air is injected into a flexible tube inside the upper mold, the outer peripheral surface of the tube is expanded by the pressure of the compressed air, thereby deforming the top or shoulder of the bean paste. Therefore, by changing the degree of protrusion of the tube into the cavity, a wide variety of bean paste products with different shapes can be provided.

Passage 3 and passage 8 are in communication. Some of the passages 8 are connected to a compressed air supply and some are connected to an alcohol supply.

As shown in FIG. 8, the brown cloth 5 is curved along the inner surface of the empty room 2, and the peripheral edge 5b is brought out of the empty room 2, and further fan-shaped from the center toward the peripheral edge 5b. The peripheral edge 5b is wound around the side surface of the upper die 1 so as to form a plurality of rows of folding folds 5e in which the folds 5c and the valley folds 5d are repeated, and fixed with a band 9 so as to be detachable. The fold widths of the mountain fold 5c and the valley fold 5d of the brown cloth 5 are arbitrary.

Two through holes 19 are provided in parallel beside the empty chamber 2 so that a part of the inner peripheral surface of the empty chamber 2 is cut out. The cutout hole of the empty chamber 2 cut out by the through hole 19 is 2a. The through hole 19 may be provided at an angle with respect to the horizontal.
A tube 20 made of a highly flexible material that can be expanded by injection of compressed air is inserted into the through hole 19, one end of the tube 20 is closed, and compressed air can be injected from the other end. When compressed air is injected into the tube 20, the tube 20 bulges out into the space 2 through the cutout hole 2a of the space 2 because it is made of a highly flexible material.

The upper die 1 is interlocked with an elevating mechanism 10 such as an air cylinder, and can be raised and lowered. A lower mold 11 is arranged below the upper mold 1, and the lower mold 11 is interlocked with an elevating mechanism 12 such as an air cylinder so as to be vertically movable. A guide plate 13 made of low-friction resin is provided around the lower die 11, and the lower die 11 is guided by the guide plate 13 to move up and down. An endless sheet 14 having a high peeling effect is provided on the guide plate 13 and wound around four guide rollers 15a, 15b, 15c and 15d to form a conveyor 16. As shown in FIG. One of the four guide rollers 15a, 15b, 15c and 15d is interlocked with a motor (not shown) so that the sheet 14 travels in the arrow A direction.
