Description

[Detailed description of the invention] The present invention relates to a bread dough forming machine.

Conventionally, in bread dough forming machines that form bread rolls, etc., the dough is rolled by one or two pairs of toning rollers, and the rolled dough is conveyed while applying a load to a load chain. By conveying on the belt,
Generally, bread dough is formed into a roll by applying friction due to the relative speed difference between the load chain and the conveyor belt.

However, in the conventional bread dough forming machine as described above, the dough may adhere to the toning roller, and if the conveyor belt is a cloth belt, hand flour may be left in the eyes of the cloth belt. If the belt becomes clogged, the frictional force between the belt and the dough is reduced, resulting in a disadvantage that bread forming such as rolling cannot be carried out reliably and satisfactorily. Furthermore, since the bread dough is rolled using only the frictional force between the dough, the conveyor belt, and the load chain, the distance of the conveyor belt must be increased in order to achieve good rolling. There were disadvantages in that the molding machine itself became large and it took time to mold the bread.

The present invention was made in view of the conventional problems as described above, and its purpose is to propose a complete bread dough forming machine that is small and lightweight and can form bread reliably and quickly. be.

Another object of the present invention is to propose a bread dough forming machine that can effectively prevent dough from adhering to rolling rollers and clogging of the conveyor belt due to hand flour.

receives the frictional force and rotates in the direction of arrow m in Fig. 3. Since there is a certain dimensional difference between the surface and the apex H of the polygonal roller 43 in the distance JL from the center, the rotation of the polygonal roller 43 with respect to the belt 22 and the elastic belt 23 is indicated by the arrow V in FIG. This results in vibrations in the vertical direction as shown. As a result, the hand flour (generally flour) adhering to the surface of the elastic belt 23 is forcibly shaken off, and the frictional force on the surface of the elastic belt 23 due to the adhesion of hand flour is effectively reduced. Prevented.

In the same way, rolling in the above-mentioned bread dough forming operation, when the dough is rolled by the rollers 9, 10, the surfaces of the rolling rollers 9, 10 are treated with Teflon. adhesion can be effectively prevented.

As explained above, according to the present invention, firstly, bread dough is rolled using the elasticity of the entire conveyor belt and the load of the load body, so that the bread dough can be reliably conveyed and rolled. Further, as a result, the distance of the conveyor belt can be shortened, so that the dough can be conveyed and rolled more quickly, and the dough forming machine itself can be made smaller and lighter. Second, the rolling rollers are treated with Teflon, which effectively prevents dough from adhering to the dough and allows for more reliable dough shaping. It becomes possible to reduce the width. Thirdly, a sheet is interposed between the conveyor belt and the load body, and by operating the sheet, the sheet and the load body can be removed from the conveyor belt, so the surface of the conveyor belt is protected. It is possible to roll the bread dough only. Fourthly, since the hand flour adhering to the conveyor belt is automatically shaken off, the reduction in the frictional force of the conveyor belt due to the adhesion of hand flour is prevented, which allows bread dough to be conveyed and rolled with a certain level of efficiency. is sustained.
