The rounding device 1 for forming a lump of bread dough into a predetermined shape by rolling a lump of bread dough (hereinafter referred to as a lump of dough; see reference numeral M in FIGS. 4A and 4B) mainly conveys the lump of dough. The endless belt 7, the drive pulley 3 and the driven pulley 5 around which the endless belt 7 is wound, the electric motor 9 that applies a rotational force to the drive pulley 3, and the endless belt 7 are arranged to face each other and come into contact with the dough mass. A rounding member 13 and a pedestal portion 11 for supporting the endless belt 7 are provided. An inverted U-shaped beam member 21 extends in a direction orthogonal to the transport direction D and is detachably mounted on the pedestal portion 11 (see FIG. 3A). The beam member 21 is omitted in FIGS. 1 and 2. Further, in FIG. 3A, a state in which the beam member 21 is fixed to the pedestal portion 11 is shown by a solid line, and a state in which one end of the beam member 21 is removed is shown by a two-dot chain line.

The substantially rectangular pedestal portion 11 in a plan view constitutes the housing of the rounding device 1 and supports a region where the dough mass rolls on the rolling surface 7a of the endless belt 7. With respect to the transport direction D, the drive pulley 3 is rotatably mounted on the upstream side of the pedestal portion 11, and the driven pulley 5 is rotatably mounted on the downstream side. Further, an electric motor 9 is arranged on the upstream side of the pedestal portion 11, and the rotational force of the electric motor 9 is transmitted to the drive pulley 3. Since the endless belt 7 is wound around the drive pulley 3 and the driven pulley 5, when the drive pulley 3 rotates, the endless belt 7 rotates due to the rotational force. Here, the endless belt 7, the drive pulley 3, the driven pulley 5, and the electric motor 9 constitute rolling means.

Further, the rounding member 13 extends from the upstream side to the downstream side of the pedestal portion 11 so as to face the rolling surface 7a which is the upper surface of the endless belt 7. As shown in FIG. 2B, the rounding member 13 of the present embodiment is composed of five rounding member pieces 13a, 13b, 13c, 13d, and 13e. The rounding member pieces 13a to 13e each have different cross sections I to V. That is, the radii of curvature of the arcuate surfaces 14a to 14e of the rounding member pieces 13a to 13e are different from each other.

Further, as shown in FIGS. 4A and 4B, the rounding member 13 has a tooth tip portion 41 capable of contacting the endless belt 7 and a rounding main body portion 43 holding the tooth tip portion 41. Have. Further, in the side view of FIG. 4A, the corners forming the right angle of the rounding main body 43 of the rounding main body 43 have an inverted L shape forming the upper surface 27 and the vertical surface 26 of the rounding member 13. The tooth tip fixing member 45 is attached. It is mounted on the tooth tip portion 41 between the tooth tip fixing member 45 and the groove portion of the rounded main body portion 43, and the tip portion of the tooth tip portion 41 comes into contact with the mounting surface 7a. The tooth tip portion 41 is mounted so that its protruding length t can be changed. The protrusion length t is changed depending on the size of the dough mass M to be molded and the like. Here, the protruding length t of the tooth tip portion 41 is the length dimension from the main body tip portion 43a to the rolling surface 7a in FIG. 4A.

The tooth tip surface 41a of the tooth tip portion 41 in contact with the dough mass M is a flat surface, and the dough mass M comes into contact with the arc-shaped arcuate surface 43b (14a to 14e) formed on the rounded main body portion 43. The rounded surface 14 of the rounding member 13 is formed (see FIG. 2B).

With this configuration, the dough mass M rolls and comes into contact with the arcuate surfaces 14a to 14e and the tooth tip surface 41a to be formed into a predetermined shape.

The rounding member pieces 13a to 13e are detachably attached, and the rounding surface having various dimensions can be appropriately changed in order to form the dough mass into a desired shape to form the rounding member.

Further, the rounding member 13 is fixed to the pedestal portion 11 via a support frame body 17 which is parallel to each other and extends upward in the vertical direction of the rounding member 13. A second swing shaft 15 extending in the vertical direction (vertical direction in FIG. 1 (b) or a direction intersecting the transport direction D or the rolling surface 7a) in the vicinity of the upstream end of the rounding member 13. One end of is attached. The other end of the second swing shaft 15 is supported by the support frame body 17, and the rounding member 13 is parallel to the horizontal plane on which the rolling surface 7a extends, centering on the second swing shaft 15. It is configured so that it can swing on the surface. That is, the rounding member 13 can be positioned so that the second rounding angle θ, which is the angle of the center line in the longitudinal direction of the rounding member 13 with respect to the transport direction D (the left-right direction in FIG. 1A), becomes a predetermined value. In FIG. 1A, the state after changing the second rounding angle θ is shown by the alternate long and short dash line. In the present embodiment, the second rounding angle θ is rotated counterclockwise with reference to the vertical plane passing through the center of the second swing axis 15 (extending in the depth direction of FIG. 1A). Let the angle be positive. The second swing shaft 15 constitutes a second angle adjusting means.

Further, as shown in FIG. 2A, the rounding member 13 has a first rounding angle which is an angle with respect to a vertical straight line (vertical direction in FIG. 2A) passing through a vertical surface 26 defining the rounding member 13. β is adjustable. A protrusion 18 provided on an extension portion (not shown) extending from the upper surface 27 defining the rounding member 13 is rotatably held by the mounting portion 16 of the rounding member 13. The mounting portion 16 is fixed to the holding portion 35, and the holding portion 35 is further fixed to the above-mentioned support frame body 17.

The protrusion 18 that functions as the first swing shaft constitutes the first angle adjusting means, and the rounding member 13 can swing around the protrusion 18. The protrusion 18 extends in the depth direction of FIG. 2A. Further, the rounding member 13 can be fixed to the mounting portion 16 by known fastening means (not shown) such as bolts and nuts so that the first rounding angle β of the rounding member 13 can be maintained at a predetermined value. In the present embodiment, the rotation angle in the clockwise direction is positive in FIG. 2A, based on the state in which the rounding member 13 is arranged so that the vertical surface 26 extends in the vertical direction.

As described above, since the second rounding angle θ can be adjusted, the dough mass can be formed into a predetermined size for the dough mass having various masses. Further, since the second rounding angle β can be adjusted, it is possible to mold dough lumps having different hardness.

Next, with reference to FIGS. 4A to 4C, the technical significance of adjusting the first rounding angle β of the rounding device 1 will be described. In FIGS. 4 (a) and 4 (b), the portion of the dough mass M close to the line of intersection where the rounded surface 14 and the mounting surface 7a intersect is referred to as a winding tail portion M1 and is directed toward the line of intersection in the rounding process. Corresponds to the bottom of the dough mass M where the epidermis of the dough mass M is stretched and closed. Further, a portion facing the winding tail portion M1 and relatively distant from the line of intersection is referred to as an exodermis forming portion M2, and the exodermis forming portion M2 corresponds to a portion constituting a spherical epidermis. However, the buttock portion M1 and the exodermis forming portion M2 are merely convenient names for facilitating explanation, and each part of the dough mass M before and after being rolled and molded by the rounding device 1 is the buttock portion M1 and the outer skin forming portion M2. It is not always distinguished by one of the exodermis forming portions M2.

Further, when the tooth tip portion 41 comes into contact with the rolling surface 7a of the endless belt 7, a part of the dough mass M is separated in the process of forming the dough mass M into a spherical shape, and the tooth tip exceeds the rounding member 13. It is possible to prevent the fixing member 45 from reaching the side.

In the process of rounding the dough mass M, the rounded surface 14 and the mounting surface 7a of the rounding member 13 stretch the skin of the dough mass M toward the roll end portion M1 so that the dough mass M becomes a sphere. It is molded into a shape. However, if the compounding material contained in the dough mass M is different, the hardness of the dough mass M is different. The soft dough mass M has a higher restoring force than the hard dough mass M.

As a result of diligent research by the inventors, by changing the first rounding angle β or changing the protrusion length t of the tooth tip portion 41 according to the magnitude of the restoring force based on the hardness of the dough mass M. , It was found that the sphericity of the dough mass M to be molded can be increased. Based on this finding, in the present embodiment, the first rounding angle β is adjusted according to the hardness of the dough mass M due to the compounding component of the dough mass M.

Specifically, when the first rounding angle β is set to 0 degrees (see FIG. 4A), the winding end portion M1 may not have a desired shape. In this case, if the first rounding angle β is set to be larger than 0 degrees (see FIG. 4B), a winding tail portion M1 having a desired shape can be obtained. Further, when the first rounding angle β of the dough mass M is set to 0 degrees, the exodermis forming portion M2 may not have a desired shape. In this case, as shown in FIG. 4C, the first rounding angle β of the rounding member pieces 13d and 13e on the upstream side in the transport direction D is set to 0 degrees, and the rounding member pieces 13a and 13b on the downstream side are set to 0 degrees. By setting the first rounding angle β of 13c to be larger than 0 degrees, the outer skin forming portion M2 having a desired shape can be obtained.

Needless to say, the number and position of the rounding member pieces in which the first rounding angle β is set to be larger than 0 degrees can be appropriately changed in order to obtain the dough mass M having a desired shape. Further, it goes without saying that the number of rounding member pieces is not limited to five and can be changed as appropriate. In the present embodiment and the modified examples described later, the rounding member is composed of a plurality of rounding member pieces, but the rounding member can also be composed of a single member.

In the rounding device 1 having the above configuration, when the dough mass prepared in the previous step is supplied from the upstream side (drive pulley 3 side) of the endless belt 7, the endless belt 7 rotates to cause the endless belt 7 to rotate. It rolls while contacting the rolling surface 7a, which is the upper surface, and the rounding surface 14 of the rounding member 13, reaches the downstream side (driven pulley 5 side) of the endless belt 7, and the dough mass is formed into a predetermined shape. .. After that, the rounded dough mass is transferred to the next step.

(Modification example)
In the present embodiment, in order to change the second rounding angle θ of the rounding member 13 with respect to the transport direction D, the rounding member 3 swings with respect to the rolling surface 7a via the second swing shaft 15. It was made possible. However, as shown in FIG. 3B, it is also possible to configure the pedestal portion 111 to be relatively movable with respect to the rounding member 113. FIG. 3B is a plan view of the rounding device 101 according to the modified example of the above embodiment. For example, it is also possible to provide a rounding device 101 capable of adjusting the second rounding angle by attaching wheels to the legs of the pedestal portion 111 and moving the pedestal portion 111 relative to the rounding member 113. Even in this modified example, it goes without saying that the pedestal portion 111 has a configuration in which the second rounding angle with respect to the rounding member 113 can be moved.

As described above, in the present embodiment, the second rounding angle θ and the first rounding angle β can be changed by swinging the rounding member 13 with respect to the pedestal portion 11, but the rounding member and the pedestal The effect of the present invention can be obtained by adopting a structure in which the portions can swing relative to each other.

The rounding devices 1 and 101 of the present embodiment and the modified examples have a configuration in which the second rounding angle θ and the protruding length of the tooth tip portion 41 can be adjusted in addition to the first rounding angle β, but the fabric to be molded In addition to the configuration in which only the first rounding angle β can be adjusted or the first rounding angle β, one of the second rounding angle θ and the tooth tip portion 41 is adjusted according to the shape and sphericity required for the mass. Needless to say, it is also possible to make a rounding device having a structure that allows it.

The rounding devices 1 and 101 of the present embodiment and the modified examples are rod-shaped rounding devices, but the present invention is not limited to the rod-shaped rounding device, and the umbrella-shaped rounding device, the tubular rounding device, and the mortar-shaped rounding device. Applicable to cup type rounding devices, umbrella types, etc. For example, in the above embodiment, the first rounding angle β and the second rounding angle θ can be adjusted with respect to the reference line extending in the transport direction or the vertical direction. However, in various rounding devices, the rounding device is concerned. A reference line conforming to the above is set, and the first and second rounding angles are adjusted with respect to the reference line.

In the present embodiment and the modified example, a lump of bread dough is used as an object to be rounded by the rolling device 1, but the rolling device of the present invention is not limited to bread and can be used for various foods.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and modifications can be made within the scope of the gist thereof.
