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-like bread dough is passed under the interdigital 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 on the belt conveyor is suppressed from the top by the spreading surface and rolled on the belt conveyor to extend it into a substantially cylindrical shape.
The bread dough having a cylindrical shape 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.

  The above-mentioned pressure spreading surface is known to be formed by setting a pressure spreading plate or a pressureless endless belt in parallel so as to face the fabric placement surface. In recent years, it has become common to use an endless belt. Yes.

For example, in the case of spreading hard bread dough, the plate for pressure spreading disclosed in Patent Document 1 is a material for strongly pressing the middle dough portion of the bread dough to strongly apply the pressure, and the dough is soft and thick. It is designed so that it can be replaced with one for spreading pressure without pushing the part particularly strongly. However, in recent years, the bread to be produced has become a wide variety, and it is common to produce the bread of a variety of bread using the same production line, so it is necessary to quickly replace the pressure-expanding member according to the bread to be produced. However, Patent Document 1 does not disclose means for that purpose. Further, in the pressure spreading section using the endless belt, no special means for adjusting according to the quality of the bread dough is provided.

  The winding portion 20 is characterized by including a guide member 14 to be described later, but in FIG. 1, in order to compare the case where the guide member of that feature is provided with the case where it is not, Of the bread dough conveyance paths provided in three rows at intervals in the width direction of the apparatus (vertical direction as viewed in FIG. 1), the guide member 14 is provided in the lower conveyance path as viewed in the figure. In addition, the upper and middle transport paths show a state in which the guide member 14 is provided. Further, the upper transport path has not yet passed the bread dough a, and the intermediate transport path has passed the bread dough. The state is shown. FIG. 2 is a perspective view of the roll-shaped bread dough forming apparatus, in which an intermediate conveyance path is composed of two rows of conveyance paths and has four rows of conveyance paths as a whole. It is substantially the same as one. In the following, the winding unit 20 will be described mainly by taking an intermediate conveyance path as an example.

  The winding part 20 was set on both sides of the conveyance path between the interdigital winding member 12 provided along each conveyance path and the interdigital winding member 12 and the mounting surface 11. And a pair of guide members 14.

  The interdigital winding member 12 includes a pair of brackets 30 attached to the frames 70 on both sides of the belt conveyor 10, and attachment shafts 32, 34, which are hung on the brackets and cross over the upper position of the belt conveyor mounting surface 11. 36, three interdigital members 38, 40, and 42 (FIG. 3) that are respectively attached to the belt conveyor and extend to the downstream side of the belt conveyor, specifically, a flexible wire mesh.

  The first interdigital member 38 from the upstream side is for starting to roll the bread dough into a roll shape from its tip by contacting the sheet-like bread dough a being conveyed, and the second interdigital member Reference numeral 40 is placed on the first interdigital member 38 and weights the first interdigital member 38 that comes into contact with the bread dough to ensure the start of the dough winding. The second interdigital member 40 extends downstream from the first interdigital member 38 and extends between the upstream ends of the pair of guide members 14. The third interdigital member 42 extends downstream so as to be placed on the guide member 14, and extends under the endless belt 26 for pressure expansion as a pressure expansion member.

  The shafts 32, 34, and 36 are spaced from the placement surface 11 enough to receive the bread dough a conveyed from the upstream side. In the guide member 14, the third interdigital member 42 placed thereon comes into contact with the bread dough started to be wound by the first and second interdigital members 38, 40, and the dough is further wound. The height is such that it can be rolled.

  It is not always necessary to use three interdigital members. Even if one interdigital member is used, it is only necessary to ensure that the dough supplied from the upstream can be wound at the upstream end portion.

  The pair of guide members 14 are attached to frames 70 on both sides of the belt conveyor 10 and supported by support frames 44 set so as to cross the belt conveyor 10. The support frame 44 is attached in parallel to the cross bar 46 corresponding to a pair of cross bars 46 provided at intervals in the bread dough transport direction and the guide members 14 forming a pair of each transport path.

A concave portion 59 that fits into the positioning convex portion 58 provided in the frame 70 is provided. As shown in FIG. 6, the support frame 44 can be attached and removed by moving it up and down with respect to the frame 70 of the belt conveyor.

  As shown in FIG. 1, the pair of guide members 14 are configured such that the distance between the guide members 14 gradually decreases from the upstream side to the downstream side of the conveyance path. That is, the bread dough supplied from the upstream side has variations in the position in the width direction of the belt conveyor, so even if there is bread dough supplied out of the conveyance path, it is received at the upstream end that accepts it. As the bread dough is conveyed to the downstream side, the bread dough is brought closer to the conveyance path, and finally the bread dough is sent to the pressure-pressing section 24 on the downstream side in a state aligned with the conveyance path. To be able to. The adjustment of the misalignment of the bread dough by the guide member is performed by rotating the bread dough in a spindle shape, so that the bread dough is tilted by contact with the guide member (that is, the center axis of the bread dough wound in the spindle shape is conveyed). In the present invention, since the interdigital member suppresses the bread dough, it is confirmed that the position adjustment is performed without substantially such inclination. doing.

  The guide member 14 is preferably made of a metal such as stainless steel, but a thin synthetic resin plate 52 is preferably attached to the upper surface of the guide member 14 with a screw 54 or the like, as shown in FIG. This is because the guide member 14 is set on the lower side of the interdigital member in which a wire mesh is actually used as described above, so that metal powder is generated due to friction with the wire mesh and is not mixed into the bread dough. It is. Accordingly, the screws are prevented from coming out above the upper surface of the synthetic resin plate 52.

  As described above, the pressure-expanding portion 24 has the pressure-endless endless belt 26 set at a position above the placement surface 11 of the belt conveyor downstream of the winding portion 20. Guide members 57 set on both sides of each conveying path for bread dough are provided between the placing surface 11 of the belt conveyor and the spreading surface of the spreading endless belt 26 adjacent to the placing surface. The bread dough passed through the pressure part 24 is guided, and both end faces of the bread dough that are spread in a cylindrical shape are formed. As shown in FIGS. 5 and 6, the guide member 57 is suspended by a support frame 55 fixed to the frame 70 of the belt conveyor adjacent to the upstream end and the downstream end of the endless belt 26 for pressure spreading.
