Description

  The present invention relates to a roll-shaped bread dough forming apparatus for forming bread dough, which is performed as a pretreatment for baking bread, into a roll shape.

  The bread making process is usually performed through the following processes.

After kneading the flour into bread dough, divide it into predetermined amounts, make it intermediate fermented,
The intermediate dough is passed through a plurality of pairs of rollers and degassed into an oval or circular sheet dough.
While the sheet-like bread dough is further transported on the belt conveyor, the sheet bread dough is passed under a comb-shaped wire mesh that is in contact with the bread dough placing surface of the belt conveyor, thereby forming a spindle shape (that is, in the axial direction). A roll with a large central part and a small diameter at both ends)
Furthermore, this spindle-shaped bread dough conveyed by the belt conveyor is suppressed from above with a spreading plate and rolled on the belt conveyor to extend it into a substantially cylindrical shape.
This cylindrical bread dough is placed on the top plate as it is, or after being secondarily formed, placed on the top plate for final fermentation, and finally put in an oven for baking.

  In the step of extending the dough in a cylindrical shape by holding the bread dough with a spreading plate, a pair of guide members extending linearly are set on both sides of the bread dough conveying path so as to form both end faces of the bread dough.

  However, when the dough is passed between a plurality of roller pairs for degassing after intermediate fermentation, the dough may be displaced in the axial direction of the rollers. When the misaligned bread dough is made into a spindle-shaped roll, passed under the pressure spreading plate and stretched into a cylindrical shape, the end of the bread dough comes into strong contact with the guide member more than necessary, and the bread dough May be damaged.

To solve this problem, before rolling the dough into a roll, the sensor detects the deviation of the dough and corrects the position of the conveyor belt carrying the dough before entering the roll dough device. Thus, an apparatus has been developed in which the bread dough is placed in an appropriate position (for example, Patent Document 1).

  However, in such an apparatus, the apparatus becomes complicated, and the length in the direction in which the bread is conveyed becomes long, and a large installation space is required.

  The object of the present invention is to solve the problems in such an apparatus.

That is, the present invention
In a roll-shaped bread dough forming apparatus for forming sheet-shaped bread dough into a roll shape,
A belt conveyor for carrying a sheet of bread dough,
An interdigital winding member that is placed in contact with the bread dough placement surface of the belt conveyor and forms the bread dough into a roll by contacting the sheet-like bread dough being conveyed;
A guide member set along at least one of both sides of a conveyance path of bread dough conveyed by the belt conveyor between the interdigital winding member and the placement surface of the belt conveyor, A pair of guide members for guiding the bread dough to align with the transport path by contacting the bread dough shifted laterally from the transport path;
The present invention provides a roll-shaped bread dough forming apparatus characterized by comprising:

  In this apparatus, even when the sheet-like bread dough is supplied in a state of being shifted in the width direction from the conveyance path, it is wound in a roll shape while its width direction position is corrected by the guide member.

  Specifically, the guide members are a pair of guide members set along both sides of the conveyance path, and the distance between the guide members is narrowed toward the downstream side across the conveyance path. Can be.

  The upstream space is widened so that bread dough that is greatly displaced in the width direction is accepted and brought closer to the transport path while being transported downstream.

  In addition, this roll-shaped bread dough forming apparatus supports the upstream edge of the interdigital winding member at a position higher than the thickness of the sheet-like bread dough from the placing surface of the belt conveyor with reference to the bread dough conveying path. The support member is configured to contact the sheet-shaped bread dough that is supported and supported by the support member and is in contact with the placement surface. The bread dough may have an upstream end portion for starting to roll the dough from its tip.

  That is, in this roll-shaped bread dough forming apparatus, since the guide member is set between the interdigital winding member and the placement surface of the belt conveyor, the interdigital winding member comes to float from the placement surface. . For this reason, the upstream end portion of the interdigital winding member is set so as to come into contact with the placement surface, thereby forming the winding start portion of the bread dough.

  Specifically, the pair of guide members are set between the mounting surface and the interdigital winding member on the downstream side of the upstream end portion of the interdigital winding member. be able to.

  The bread dough that has entered at a shifted position can be guided toward the conveyance path after the dough has been wound to some extent, so that it is downstream of the upstream end portion of the interdigital winding member. A guide member is provided on the surface. However, the pair of guide members extend from the upstream end of the interdigital winding member toward the downstream side, and the upstream end portion of the interdigital winding member is placed between the guide members on the belt conveyor mounting surface. It can also be touched.

More specifically,
The interdigital winding member is
A first interdigital member supported by the support member, the first interdigital member being set to contact the mounting surface and forming the upstream end portion of the interdigital winding member When,
The pair of guide members is set between the mounting surface and the second interdigital member extending in the transport direction along the pair of guide members.

  Although the interdigital winding member can be formed from a single interdigital member, it is desirable that the interdigital member be formed of two interdigital members.

  In this case, the first interdigital member has at least first and second interdigital members arranged sequentially from the upstream side to the downstream side, and the first interdigital member comes into contact with the bread dough. The second interdigital member can be overlapped and weighted to the first interdigital member.

  By weighting, the start of winding the dough can be made more reliable.

  Further, in this roll-shaped bread dough forming apparatus, a plurality of dough conveyance paths are defined on the placement surface of the belt conveyor at intervals in parallel with each other in the width direction. The interdigital winding member and the pair of guide members may be provided.

  Further, in this roll-shaped bread dough forming apparatus, the distance between the guide members can be adjusted by a guide member support frame which is set so that the pair of guide members crosses the upper position of the placement surface of the belt conveyor. Can be supported.

  The interval can be adjusted according to the mass of bread dough to be rolled.

  Each of the guide members can have a surface in contact with the interdigital winding member formed of a synthetic resin.

  Thereby, it can prevent that a winding member and a guide member rub and metal powder generate | occur | produces.

  The guide member support frame can be detachably set on the frame of the belt conveyor disposed along both side edges in the width direction of the bread dough placement surface. The distance between the guide members set on both sides of the conveyance path needs to be adjusted by the bread dough to be roll-formed, and the guide member support frame is set so as to be detachable from the belt conveyor frame. It is easy to adjust the mounting of the.
