Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a device for rolling up pieces of bread dough.
The aim is to completely eliminate molding errors during high-speed molding and reduce production costs.

(Prior art) Conventionally, in the production of croissants and bread rolls, rolling up pieces of dough divided into predetermined sizes from one side and forming them requires the movement of a conveyor that transports the pieces of dough and a belt that moves in the opposite direction. It is known that the belts are arranged vertically to face each other, and the fabric is rolled up using the gaps between the top and bottom of the belt.

(Problem to be Solved by the Invention) When rolling up a piece of dough in the above-mentioned prior art, if the center line of the divided dough piece does not correctly match the advancing line of the conveyor, it will be rolled up diagonally. , the shape is not a symmetrical anti-spindle shape, but becomes amorphous and loses its commercial value.

This problem is called "uneven winding", and in order to eliminate this occurrence, a device is required to correctly orient the center line of the divided dough pieces in the direction of movement of the conveyor.

Before the divided dough pieces enter the winding device, they are rolled by upper and lower rollers in order to exhaust the gas contained in the dough pieces to the outside and make the inside of the dough have a certain density. By rotating at a slower speed than the downstream transport conveyor and slipping the dough pieces on the downstream conveyor while they are being sandwiched between rolling rollers, the center line of the divided dough pieces is made to coincide with the direction of travel of the conveyor. I can do it.

However, when the dough piece is rolled by this rolling roller, the gas contained inside the dough piece gathers in the form of air bubbles at the rear end of the dough piece in the process of being discharged to the outside by rolling (see Figure 5). ), when a piece of dough is stretched thinly, due to the air bubbles that exist unevenly, the left and right sides are not stretched evenly, and the rear end bends to one side (Figure 4), and as a result, when rolled up,
This results in uneven winding.

(Means and effects for solving the problem) In order to solve the above-mentioned drawbacks, the present invention provides a dough piece pressing device close to the upstream side of a pair of rolling rollers positioned above and below. It is.

This piece of dough pressing device is provided with a plurality of flexible belts stretched between two rollers close to the upstream side of the rolling roller, and the belts are placed with a predetermined gap between them and the conveyor. It is slower than a roller and operates at the same speed as a conveyor.

When the dough piece passes through the pressing device, the belt holds the dough piece in the running direction (Fig. 3), so the dough piece is free from irregularities at the rear end of the dough piece caused by the flow of air bubbles. This belt holds the belt against bending due to excessive stretching.

Furthermore, because the dough is rolled while being stretched in the advancing direction due to the speed difference between the rolling roller and the pressing device, the number of turns of the dough piece can be increased during winding up in the subsequent process.

(Example) Hereinafter, the present invention will be explained based on an example.
A first conveyor 2 conveys dough pieces 1 divided from a dough sheet, and a pair of rolling rollers consisting of an upper roller 3 and a lower roller 4 are provided in connection with the first conveyor 2 downstream thereof.

Further, a second conveyor 5 is provided downstream of the rolling roller, and a winding mechanism comprising a roller 6, a third conveyor 7, and an upper belt 8 is provided downstream of the second conveyor 5.

The first conveyor 2, rolling rollers 3, 4, second conveyor 5, and third conveyor 7 are driven by motors 9, 10, 11, 12, and 14, respectively, and the speed increases toward the downstream. There is.

A roller 17 and a roller 18 are provided on the first conveyor 2 in the vicinity of the rolling roller 3, and a pressing device in which a plurality of round belts 19 are stretched is provided between the rollers 17 and 18.

The round belt 19 is driven by the motor 13 and is conveyed at the same speed as the first conveyor 2.

The conveyance speed of the first conveyor 2 and the round belt 19 is slower than the conveyance speed of the rolling rollers 3 and 4 to provide a speed difference.

In the figure, 15 is a motor that drives the roller 6, and 16 is a motor that drives the upper belt 8.

Next, the function and effect will be described. When the dough piece 1 is conveyed and passes through the gap between the round belt 19 and the first conveyor 2, the round belt 19 presses the dough piece 1 while conveying it.

The dough piece 1 is then rolled in the area of rolling rollers 3, 4.

During this rolling, the gas contained in the dough piece gradually flows to the rear and collects, generating air bubbles, making that part extremely stretchable.

Since the round belt 19 is holding down the moving direction of the dough piece 1 (Fig. 3), the air bubble part
It only extends downstream in a straight line, and the tail of the fabric piece does not bend to the left or right.

If this pressing device is not provided in front of the rolling rollers 3 and 4, the dough will be stretched by the rolling rollers 3 and 4 and air bubbles generated at the rear end of the dough piece will cause
The trailing edge of the piece of fabric stretches irregularly, resulting in it bending from side to side.

Also, due to the difference in conveying speed between the round belt 19, the first conveyor 2, and the rolling rollers 3 and 4, the passing dough piece becomes taut, and the dough piece becomes thinner as it stretches in the direction of travel. A piece of fabric stretched in the direction can increase the number of turns.

(Effects of the Invention) As explained above, the present invention prevents bending from the leading edge to the trailing edge of the conveyed piece of dough when rolling it. By eliminating molding errors, we were able to significantly reduce production costs.
