Description

The present invention relates to a rounding device used in a process of rolling a divided irregular dough ball after dividing a food dough such as a kneaded bread dough into a predetermined size.

In the bread making process, after kneading the bread dough with a mixer, it is necessary to divide the bread dough into a predetermined size according to the size of the baked bread. The cut portion remains in the divided bread dough (hereinafter referred to as "dough ball"), and if the fermentation process is proceeded as it is, the carbon dioxide gas generated in the fermentation process escapes from the dough and the baked bread is baked. The result will be worse. For this reason, when a large amount of bread is produced in a bakery factory, the dough balls continuously discharged from the dividing machine are sequentially sent to the rolling device, and the dough balls having an irregular shape after the division are rounded to prepare the skin. Need to form.

As this kind of rounding device, various types have been proposed, such as one using a rotating drum, depending on the number of dough balls to be rounded and shaped per unit time. As one of them, as disclosed in Patent Document 1, there is known a method in which a dough ball is rounded and shaped while being conveyed in a certain direction by an infinitely circulating transport belt. In this rounding device, the transport belt is hung around a pair of drive rolls and driven rolls whose axial direction is inclined in the horizontal direction, and a single guide member faces the belt surface of the transport belt. Have been placed. The guide member is a long member having a concave groove, and by making the concave groove face the belt surface of the transport belt, a transport passage for a dough ball is formed between the guide member and the transport belt. There is. Further, the guide member is provided so as to diagonally cross the belt surface of the transport belt.

In such a rounding device of Patent Document 1, when a dough ball is supplied to the start end of the transport passage, the dough ball advances while rolling in the transport passage with the rotation of the transport belt, and rounding shaping is performed. After being made, it is discharged from the end of the transport passage. Since the guide member is provided so as to diagonally cross the belt surface of the transport belt, the dough ball causes a lateral slip with respect to the transport belt when rolling in the transport passage. By doing so, the skin of the dough ball is evenly arranged.

Japanese Patent Application Laid-Open No. 1-243939

However, in the rounding device disclosed in Patent Document 1, when the inclination angle of the guide member with respect to the rotation direction of the transport belt becomes small, the slip amount of the dough ball with respect to the transport belt decreases, so that the rounding shaping with respect to the dough ball is performed. Was inadequate. In addition, if the total length of the dough ball transport passage is shortened, there is a concern that the rounding and shaping will be insufficient.

On the other hand, if the inclination angle of the guide member with respect to the rotation direction of the transfer belt is set sufficiently large and the total length of the transfer passage of the dough ball is set sufficiently long, it is orthogonal to the rotation direction of the transfer belt. There is a problem that the size in the direction, that is, the width of the transport belt becomes large, and the rounding device itself becomes large.

Further, the dough balls that have been rounded are sent to the intermediate fermentation, but depending on the type of bread dough to be produced, the rounding device alone may not be sufficient for the rounding. In such a case, it is convenient to be able to perform additional rounding and shaping on the dough balls while transporting the dough balls between the steps.

The present invention has been made in view of such a problem, and an object of the present invention is that it is possible to perform rounding and shaping of the dough balls in accordance with the transportation of the dough balls between processes, and the size of the entire apparatus is small. It is an object of the present invention to provide a food dough rounding device capable of performing good rounding even if it is made into a product.

That is, in the rounding device of the present invention, the rotating shaft is provided so as to be inclined with respect to the horizontal direction, and the pair of transport rolls are stretched between the transport rolls to rotate and form a rolling surface of the dough ball. A transport belt is provided, and a plurality of guide members that are arranged to face the rolling surface and cooperate with the rolling surface to form a running groove of a cloth ball. Then, the plurality of guide members are arranged at an angle with respect to the traveling direction of the transport belt, and are arranged in a row along the traveling direction of the rolling surface of the transport belt, and the traveling grooves are connected in multiple stages. A transport passage for the dough balls is formed along the rolling surface, and the downstream end of the traveling groove of each guide member exists at a position higher than the upstream end of the traveling groove located at the rear stage.

According to the present invention, among the running grooves of the dough balls connected in multiple stages along the transport belt, there is a step between the running grooves that move back and forth along the rolling direction of the dough balls. Since the dough balls fall down the step when transferring between the front and rear running grooves, the width of the carrying belt can be reduced even if the running grooves are connected in multiple stages to form a dough ball transport passage. It can be suppressed, and the rounding device using the transport belt can be slimmed down.

In addition, the posture of the dough ball changes each time it moves between the traveling grooves that move back and forth in the transport passage, and the rounding and shaping of the dough ball is promoted. It becomes possible to perform shaping, it is possible to reduce the size of the rounding device, and it is possible to perform sufficient rounding shaping on the dough ball regardless of the type of dough.

It is a front view which shows an example of embodiment of the food dough rolling apparatus to which this invention is applied. It is a top view which shows an example of embodiment of the food dough rolling apparatus to which this invention is applied. FIG. 3 is a cross-sectional view taken along the line III-III of FIG. It is the figure which showed the part of the transport passage of the dough ball simply.

Hereinafter, embodiments of a food dough rounding device to which the present invention is applied will be described with reference to the accompanying drawings.

1 to 3 show an example of an embodiment in which the present invention is applied to a bread dough rolling device. FIG. 1 is a front view, FIG. 2 is a plan view, and FIG. 3 is a sectional view taken along line III-III of FIG. Is. This rounding device 1 is used in combination with a dough dividing machine (not shown), receives dough balls that are divided into predetermined sizes and discharged one after another by a belt conveyor from the dividing machine, and these dough. It is configured to perform a rounding process while transporting the balls in a straight line and discharge them for the next process.

The rounding device 1 includes a transport belt 2 that sends the dough balls received from the splitting machine to a process on the downstream side, and a dough ball transport passage 3 is provided over the entire length of the transport belt 2. The arrow line A in FIG. 1 is the transport direction of the dough ball in the transport passage 3. The dough ball advances while rolling in the transport passage 3, and at that time, rounding and shaping are performed. At the end of the transport passage 3, a discharge chute 30 for dropping the rounded dough balls into the next processing step is provided, and the dough balls that have rolled in the transport passage 3 roll down to the discharge chute 30 as they are. It has become like.

A dusting powder storage box 31 is provided above the discharge chute 30, and the dusting powder drops in a fixed amount from the storage box 31 to the vicinity of the inlet of the discharge chute 30 while the transport belt 2 is rotating. It has become. As a result, the dough balls 3 that have rolled out from the transport passage 3 to the discharge chute 30 are sent to the next step in a state of being dusted with dust.

The transport belt 2 has an endless shape and is hung on a pair of transport rolls (not shown) to form a rolling surface 20 of the dough ball. The pair of transport rolls are rotatably held with respect to the apparatus frame 10, and the distance between the pair of transport rolls can be finely adjusted by an adjustment mechanism (not shown), whereby the transport belt 2 can be attached. The acting tension can be adjusted. Further, the rotational output of the motor 21 is transmitted to one of the transport rolls, whereby the transport belt 2 rotates in a predetermined path partitioned by the pair of transport rolls. By controlling the motor 21, the rotation speed of the transport belt 2 can be appropriately adjusted according to the discharge speed of the dough balls in the splitting machine.

The pair of transport rolls are inclined at a predetermined angle (for example, 45 degrees) with respect to the horizontal direction in the rotation axis direction, and as shown in FIG. 3, the rolling surface 20 of the dough ball in the transport belt 2 is oblique. It is inclined to. Further, a plurality of guide members 4 are arranged to face each other on the rolling surface 20, and the transport belt 2 and the plurality of guide members 4 form a dough ball transport passage 3. The plurality of guide members 4 are supported by the frame 10 and are arranged in series along the traveling direction of the rolling surface 20 of the transport belt 2.

Each guide member 4 includes a bottom plate 40 fixed to the device frame 1 and a guide plate 41 supported by the bottom plate 40. The bottom plate 40 has its end surface facing the rolling surface 20 of the transport belt 2 and is held by the device frame 10 in a state orthogonal to the rolling surface 20. Therefore, a traveling groove 42 having a substantially V-shaped cross section is formed by one surface of the bottom plate 40 and the rolling surface 20 of the transport belt 2, and the traveling groove 42 formed by each guide member 4 is formed in the traveling direction of the transport belt 2. The above-mentioned dough ball transport passage 3 is configured by connecting in series along the above-mentioned.

One surface of the bottom plate 40 forming the traveling groove 42 is inclined with respect to the traveling direction of the rolling surface 20 of the transport belt 2, and the traveling groove 42 is an end portion of the dough ball on the downstream side in the rolling direction. Is provided at a higher position than the upstream end. That is, the dough ball is moving in the width direction of the transport belt 2 while rolling in the traveling groove 42 of each guide member 4. Further, although the guide member 4 is fixed to the device frame 10 via the support member 11, the inclination angle of the bottom plate 40 with respect to the traveling direction of the transport belt 2 is arbitrarily adjusted, and the guide member 4 is combined with the transport belt. In order to adjust the sliding contact condition of the bottom plate, the support member 11 has an adjusting mechanism for a fixed position of the bottom plate 40.

The guide plate 41 has a concave surface that covers the transport belt 2, and the distance between the concave surface and the rolling surface 20 of the transport belt 2 is arbitrarily adjusted according to the size of the dough ball. Is possible. Therefore, the dough ball existing in the traveling groove 42 is sandwiched between the rolling surface 20 of the transport belt 2 and the guide plate 41, and the guide plate 41 progresses as the transport belt 2 advances. It rolls while in contact with the dough ball, whereby the dough ball is rounded and shaped in the traveling groove 42.

At the entrance of the transport passage 3, an inlet member 5 for receiving the dough balls sent from the splitting machine is provided. The inlet member 5 has a bottom plate 50 and a guide plate 51 similar to the guide member 4, but the guide plate 51 receives the dough ball dropped from above into the transport passage 3, so that the guide plate 51 has the transport belt 2. It stands up without covering the rolling surface 20 of the above, and guides the dough ball to the traveling groove 42 of the guide member 4 located at the rear stage.

FIG. 4 is a diagram simply showing a part of the dough ball transport passage 3 constructed along the transport belt 2. As described above, each guide member 4 cooperates with the rolling surface 20 of the transport belt 2 to form a running groove 42 of the dough ball 6, and a plurality of guide members 4 are connected in the traveling direction of the transport belt 2. By arranging them in series, the transport passage 3 of the dough balls 6 in which the traveling grooves 42 are connected in multiple stages is configured. The arrow A direction in the figure is the traveling direction of the transport belt 2. As the transport belt 2 advances in the direction of the arrow A, the dough ball 6 moves in the direction of the arrow A in the transport passage 3 while rolling inside the traveling groove 42.

As shown in FIG. 4, the upstream end of the traveling groove 42 of the guide member 4B exists at a position lower than the downstream end of the traveling groove 42 of the guide member 4A located in the front stage. The downstream end of the traveling groove 42 of the guide member 4B exists at a position higher than the upstream end of the traveling groove 42 of the guide member 4C located at the rear stage. That is, in the transport passage 3 of the cloth ball 6, there is a step at the connection portion of each running groove 42, and each time the cloth ball 6 moves from the running groove 42 in the front stage to the running groove 42 in the rear stage, it is shown in the drawing. As shown by the alternate long and short dash line, the step is dropped and the inside of the transport passage 3 is moved like a saw blade.

In the rounding device 1 of the present embodiment configured as described above, the dough balls 6 existing in the traveling grooves 42 of each guide member 4 roll in the traveling grooves 42 by the rotation of the transport belt 2. The bottom plate 40 of the guide member 4 is provided diagonally with respect to the traveling direction of the transport belt 2, and the dough balls are slantingly moving on the transport belt 2 while causing slippage. As a result, the dough ball that rolls in the traveling groove 42 is rounded and shaped.

Further, as described above, the transport passage 3 of the dough ball 6 is configured by connecting a plurality of traveling grooves 42 in multiple stages, but the connecting portion of these traveling grooves 42 has a reverse step higher on the front stage side than on the rear stage side. Therefore, even if a plurality of traveling grooves 42 are connected in multiple stages to form the transport passage 3, the width W (see FIG. 4) of the transport belt 2 is the movement of the dough balls in each guide member 4. It is only necessary to correspond to the quantity. Therefore, even if the number of steps of the traveling groove 42 is increased to increase the total length of the transport passage 3 in consideration of sufficient rounding shaping for the dough ball, the width of the transport belt 2 can be kept small and rounded. It is possible to reduce the size of the device 1.

In addition, the dough ball 6 traveling in the transport passage 3 drops the reverse step each time it moves from the traveling groove 42 on the front stage side to the traveling groove 42 on the rear stage side, and at the time of this fall, the fabric ball 6 falls on the guide plate 41. You will be released from the restraint by and change your posture. That is, the dough ball 6 changes its rotation direction each time it moves over the traveling groove 42, and the dough ball 6 passes through the traveling groove 42 in a plurality of stages to promote the rounding and shaping of the dough ball 6, and as a result, the rounding and shaping of the dough ball 6 is promoted. While suppressing the total length of the transport passage 3 and reducing the size of the entire device, it is possible to sufficiently round the dough balls.

Therefore, in the rounding device 1 to which the present invention is applied, it is possible to reduce the size and size of the rounding device while promoting the rounding and shaping of the dough ball. Further, the rounding device 1 to which the present invention is applied is capable of linearly transporting the dough balls and performing efficient rounding shaping in accordance with the transport, and is capable of performing efficient rounding shaping with the conveying device of the dough balls 6 between processes. It is possible to use the device as well.

In the above-described embodiment, the bread dough kneaded as the food dough has been described as an example, but the rolling device of the present invention may be applied to other food dough.
