Description

The present invention relates to a dough sheet shaping apparatus and method for shaping a dough into a sheet shape.

Conventionally, the manufactured dough balls have been divided and formed into a sheet by a rolling roller or the like. The sheet-shaped dough is used, for example, for arranging various foodstuffs and molding the dough so as to wrap the foodstuffs.

When molding the dough into a sheet shape, it is necessary to adjust the shape and thickness to a predetermined shape according to the application. For example, when wrapping a food material and forming it into a round shape, it is preferable to form it into a substantially circular shape, and it is preferable to adjust the thickness to a uniform thickness or to adjust the peripheral portion thinly.

As a technique for forming such a dough, for example, Patent Document 1 describes that the dough is stretched, then changed in direction, spread from another direction, and shaped into a sheet. Further, Patent Document 2 describes that the dough is shaped into a spherical shape and then flattened into a disk shape.

Jikkai Sho 58-83287 Japanese Unexamined Patent Publication No. 2006-304662

When a dough such as bread dough is manufactured and molded into a predetermined shape, a step of manufacturing a predetermined amount of dough with a manufacturing device such as a molder, a step of dividing the manufactured dough, and a step of molding the divided dough balls are performed. Will be done. Since the doughs collectively produced by the batch processing are divided and then sequentially molded, the divided dough balls have different times until they are formed. Since the physical properties of the dough change with the passage of time due to fermentation or the like, the elongation and elasticity of the dough during molding will change depending on the dough balls.

In the above-mentioned patent document, the dough balls are spread and formed into a sheet shape, but when treated in a certain manner, the shape of the dough sheet formed due to the change in the physical properties of the dough balls becomes irregular and the same quality. There is a problem that it becomes difficult to mold a molded product.

Further, the rolling section includes a pair of rolling rollers for rolling the dough, and the adjusting section adjusts the distance between the rolling rollers as the rolling amount. Further, the adjusting unit adjusts the next rolling amount based on the rolling amount and the shape data of the next cloth sheet after adjusting with the rolling amount.

According to the present invention, by having the above-mentioned structure, the dough sheet can be shaped in response to changes in the physical properties of the dough.

It is a schematic plan view about the Embodiment which concerns on this invention. It is a schematic front view about embodiment which concerns on this invention. It is explanatory drawing which shows the shaping process of a cloth sheet.

Hereinafter, embodiments according to the present invention will be described in detail. Since the embodiments described below are preferable specific examples for carrying out the present invention, various technical restrictions are made, but the present invention clearly states that the invention is particularly limited in the following description. Unless otherwise specified, it is not limited to these forms.

FIG. 1 is a schematic plan view of an embodiment according to the present invention, and FIG. 2 is a schematic front view thereof. The dough sheet shaping device 1 includes a conveying section 2 for transporting the dough, a first rolling section 3 and a second rolling section 4 for rolling the dough into a sheet shape, and a direction changing section for changing the direction of the rolled dough. 5 and the photographing unit 6 which is a recognition unit for recognizing the shape of the rolled dough sheet, and the adjustment for adjusting the rolling amount of the rolled portion based on the photographed image of the dough sheet which is the recognized shape data of the dough sheet. It is provided with a part 7.

The transport unit 2 includes transport conveyors 2a to 2c arranged on a base, and the transport conveyors 2a to 2c are arranged so that their respective transport directions are linear. Then, the dough carried into the conveyor 2a is shaped while being sequentially transferred to the conveyors 2b and 2c.

The first rolling portion 3 is arranged between the conveyors 2a and 2b, and includes a first upper rolling roller 3a and a first lower rolling roller 3b. The first upper rolling roller 3a and the first lower rolling roller 3b are arranged so as to face the upper side and the lower side of the fabric transport path. The first rolling portion 3 includes a position adjusting mechanism 3c that adjusts the position of the first upper rolling roller 3a in the vertical direction, and the first lower rolling roller 3b is attached so as not to move in the vertical direction. .. Therefore, by moving the first upper rolling roller 3a up and down by the position adjusting mechanism 3c, the distance between the first upper rolling roller 3a and the first lower rolling roller 3b can be adjusted, and both rolling compactions can be adjusted. It is possible to adjust the rolling amount of the dough passing between the rollers.

A dough detection sensor 3d is attached to the first rolling portion 3 on the downstream side in the conveying direction of the rolling roller, and measures the time for the conveyed dough to pass. Since the passing time of the dough corresponds to the dough speed when rolling the dough, it can be used as a parameter when adjusting the rolling amount.

The second rolling portion 4 is arranged between the conveyors 2b and 2c, and includes a second upper rolling roller 4a and a second lower rolling roller 4b. The second upper rolling roller 4a and the second lower rolling roller 4b are arranged so as to face the upper side and the lower side of the fabric transport path. Like the first rolling section 3, the second rolling section 4 includes a position adjusting mechanism 4c that adjusts the position of the second upper rolling roller 4a in the vertical direction, and is between the second rolling section 4 and the second lower rolling roller 4b. It is designed to adjust the interval of. Further, similarly to the first rolling section 3, a dough detection sensor 4d is attached to the downstream side of the rolling roller in the conveying direction, and the time required for the conveyed dough to pass is measured.

The direction changing portion 5 includes a pair of frame members 5a that bring the fabrics into contact from both sides, a drive mechanism 5b that supports the frame members 5a and brings them approaching or separating from each other, and a rotation mechanism 5c that rotates the drive mechanism 5b. ing. Then, the frame members 5a are brought into close contact with the dough positioned below the direction changing portion 5 and brought into contact with each other, and the dough is rotated 90 degrees in a state where the frame member 5a is in contact with the dough to bring the dough into the transport direction. It is rotated 90 degrees. Therefore, the transport direction of the dough itself is changed by 90 degrees, and the second rolled portion 4 rolls from the direction intersecting the rolled direction in the first rolled portion 3 at 90 degrees.

The photographing unit 6 is arranged on the downstream side of the second rolling unit 4 in the transport direction, and takes a picture of the rolled dough sheet from above with a taking camera to recognize the shape of the dough sheet. Then, based on the photographed image of the fabric sheet, parameters related to the shape in the shaped state such as the outer shape of the fabric sheet are acquired.

In this example, it is arranged on the downstream side of the second rolled portion 4, but another photographing portion is arranged on the downstream side of the first rolled portion 3 and the rolled dough is photographed in each rolled portion to form a shaped state. You may be able to recognize the shape of.

When the length in the rolling direction is used as the shape data of the dough sheet, it can be calculated based on the detection result of the dough detection sensor. For example, the length in the transport direction (rolling direction) may be calculated by multiplying the transport speed of the transport conveyor and the detection time of the dough.

The adjusting unit 7 adjusts parameters such as the distance between the rolling rollers of the first rolling unit 3 and the second rolling unit 4 and the dough speed based on the parameters related to the shape of the shaped state transmitted from the photographing unit 6 to roll. Adjust the amount. As the adjusting unit 7, a known information processing device such as a CPU, a memory, an input key, and a display panel can be used, and a desired function can be realized by inputting a program and data necessary for processing. Become.

To adjust the rolling amount, for example, data on the length of each rolled portion in the rolling direction is acquired based on a photographed image of the outer shape of the dough sheet, and the distance between the rolling rollers of the rolled portion is adjusted by the difference from the reference value. do. By making such adjustments, the shape of the dough sheet can be shaped so that the length in the rolling direction is close to the reference value.

When the dough is sheet-shaped in order, the characteristics such as the elongation and elasticity of the dough change as the order becomes later. Therefore, the length in the rolling direction gradually deviates from the reference value, but by accumulating the shape data of the dough sheet in the shaped state one by one, the transition of the difference with respect to the reference value is quantitatively measured. can do. In the above-mentioned example, by accumulating the captured images for each of the fabric sheets, it is possible to perform more accurate analysis as the accumulated number of sheets increases.

Then, the rolling amount is adjusted by the difference from the reference value of the dough sheet, the previous adjustment result of the rolling amount is confirmed by the difference from the reference value of the next dough sheet, and the rolling amount is adjusted based on the adjustment result. , It is possible to maintain the length in the rolling direction close to the reference value.

Then, it is possible to analyze the correlation between the adjustment value regarding the parameter of the rolled portion and the transition of the difference, and obtain the optimum adjustment value for the change in the characteristics of the dough. By accumulating shape data and analysis data related to such a dough sheet, adjustment processing using a known inference program such as artificial intelligence can be performed. In that case, more accurate adjustment processing can be performed by adding conditions such as the raw material of the dough and the ambient temperature.

FIG. 3 is an explanatory diagram showing a shaping process of the fabric sheet. In the first rolling section 3 and the second rolling section 4, the positions of the upper rolling rollers 3a and 4a in the vertical direction are adjusted by the position adjusting mechanisms 3c and 4c, and the intervals are set in advance. It is preferable that the distance between the rolling rollers of the first rolling portion 3 on the upstream side in the transport direction is set wider than the distance between the rolling rollers of the second rolling portion 4 on the downstream side in the transport direction. The adjusting unit 7 presets a reference value regarding the length of the dough shaping sheet in the rolling direction.

First, the rolled dough ball F is carried into the conveyor 2a (FIG. 3A). The dough ball F is conveyed by the conveyor 2a and introduced into the first rolling section 3, and the dough ball F is rolled by rotating the first upper rolling roller 3a and the first lower rolling roller 3b. The dough ball F is thinly rolled so as to spread in the transport direction to form an elliptical dough sheet G (FIG. 3 (b)). In this case, the transport direction is the rolling direction A with respect to the dough ball F.

The rolled dough sheet G is led out to the transport conveyor 2b and conveyed, and the rolling speed is calculated by the time when the dough sheet G is detected by the dough detection sensor 3d and passes through. The frame member 5a is brought into contact with both sides of the fabric sheet G and rotated by 90 degrees after being conveyed to the turning position by the conveyor 2b and temporarily stopped (FIG. 3 (c)). In this case, since the frame member 5a is brought into contact with the dough sheet G from a direction orthogonal to the rolling direction A in the first rolling portion 3, the length of the dough sheet G in the rolling direction A does not change. The direction of the dough sheet G can be changed.

After the direction is changed, the dough sheet G is conveyed by the conveyor 2b and introduced into the second rolling section 4, and the second upper rolling roller 4a and the second lower rolling roller 4b are rotated to roll the dough sheet G. do. The dough sheet G is thinly rolled so as to spread in the transport direction to form a substantially circular shaped sheet H (FIG. 3 (d)). The rolled shaped sheet H is led out to the transport conveyor 2c and conveyed, and the rolling speed is calculated by the time when the shaped sheet H is detected by the dough detection sensor 4d and passes through.

In this case, since the transport direction is the rolling direction B with respect to the dough sheet G, in the shaping sheet H, the rolling direction B of the second rolling portion 4 is orthogonal to the rolling direction A of the first rolling portion 3. , The shaping sheet H is rolled in the directions orthogonal to each other and shaped into a circle.

The shaping sheet H is photographed from above by the photographing unit 6 to acquire an image of the shaping sheet H. The adjusting unit 7 calculates the lengths of the rolling directions A and B from the outer shape of the shaping sheet H based on the acquired captured image. Then, the distance between the rolling rollers of the first rolling portion 3 is adjusted by the difference between the length of the rolling direction A and the reference value. For example, if the length of the rolling direction A is shorter than the reference value, the interval amount is adjusted so that the interval between the rolling rollers becomes narrower, and if it is longer than the reference value, the interval amount is increased so that the interval is widened. adjust.

Further, the distance between the rolling rollers of the second rolling portion 4 is adjusted by the difference between the length in the rolling direction B and the reference value. For example, if the length of the rolling direction B is shorter than the reference value, the interval amount is adjusted so that the interval between the rolling rollers becomes narrower, and if it is longer than the reference value, the interval amount is increased so that the interval is widened. adjust.

Then, based on the captured image of the next shaping sheet H, the effect of the previous adjustment of the interval amount is confirmed by the difference from the reference value in the rolling directions A and B, and the next interval amount is adjusted. For example, check the adjustment result by calculating the decrease in the difference due to the previous interval, calculate the ratio to the decrease for the difference this time, and multiply the previous interval by the ratio to calculate the next interval. To adjust.

In this way, since the rolling amount is adjusted based on the photographed image of the dough sheet, the dough sheet can be shaped according to the change in the physical properties of the dough. Further, since the result of adjusting the rolling amount is confirmed based on the photographed image of the next dough sheet and the next rolling amount is adjusted, the dough sheet can be stably shaped.

In the example described above, the case of shaping a circular shaping sheet by changing the direction is shown, but various curved shaping sheets such as an elliptical shape, an oval shape, an egg shape, and an oval shape other than the circular shaping sheet are shown. It can be applied to, and is not particularly limited. For example, in the above example, by rolling the first rolled portion 3 and the second rolled portion 4 stepwise in the same direction without changing the direction, the shape can be formed into an elliptical shape or an oval shape.

Further, as the reference value when adjusting the rolling amount, predetermined data can be input and used as the reference value, but the data calculated in the upstream or downstream process of the dough sheet shaping process can be used. It is also possible to set a reference value based on this. For example, by collecting data related to yield and quality control in each process in real time and correcting standard values in real time based on the collected data, it is possible to efficiently manufacture high-quality molded products. It is expected that this will greatly contribute to the improvement of productivity.
