Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for rolling up croissant dough, and aims to reduce production costs by completely eliminating operational errors during high-speed forming. It is.

(Prior Art) Conventionally, in the production of croissants, devices that roll up triangular dough divided into predetermined sizes from the base and form it are either a flexible cloth band stationary on a conveyor that conveys the dough, or a device that moves the dough while the conveyor is moving. A belt running in the opposite direction is placed close to the belt, and the fabric is rolled up in this close gap.

(Problems to be Solved by the Invention) In the above-mentioned prior art device, the winding results are not all as expected, but "unwinding" and "unwinding" occur due to inevitable causes. The aforementioned loss of several percent, sometimes tens of percent, occurred due to defective products that could not be sold as products.

The inevitable cause of this "unrolling" is that flour etc. are attached to the dough to prevent it from sticking to other parts when forming the croissant dough into sections or transporting the dough. Eliminating the need for sticky hands will eliminate the problem of unrolling, but this has led to other processing problems such as sticking during dividing and transporting the dough.

In addition, "rolling up from one side" occurs when the center line of the divided dough is not correctly oriented in the moving direction of the conveyor, that is, when it enters the winding device at an angle, and the shape of the croissant is not uniformly spindle-shaped. It becomes amorphous and loses its commercial value.

(Means and effects for solving the problems) The apparatus of the present invention is intended to completely eliminate machining errors that frequently occur due to these reasons.

The device of the present invention first prevents "rolling up from one piece" by clamping the divided fabric pieces with upper and lower rollers before entering the winding device, and pressing the upper and lower clamps at a slower speed than the transport conveyor in the downstream winding device. By rotating the pressure roller, the center line of the elongated divided dough piece can be made to coincide with the advancing direction of the conveyor, thereby preventing "rolling up from one piece".

However, in this case, if the divided dough has hand flour etc. attached to it, the dough can enter the winding device without sticking to the rollers, but as mentioned above, the product will unwind and new losses will occur. It is.

Therefore, the present invention makes it possible to reliably transport the divided dough without using hand flour and to supply it to the winding device. A small-diameter shaft that rotates in the same direction as the roller at a speed faster than its circumferential speed is provided to pass through the gap between the rolling rollers.

Therefore, the divided dough is fed to the rolling rollers in a sticky state, and the dough stuck to the rolling rollers is peeled off by a small diameter shaft and fed to a downstream winding device.

In this way, winding losses such as unwinding can be reduced because the roll is rolled up by passing through the gaps between rolling rollers without using hand flour.

(Example) The structure of the present invention will be explained based on FIG. 1 as an example. First conveyor 2 conveying divided dough 1
An upper roller 3 and a lower roller 4 as a pair of rolling rollers are provided above and below in connection with the downstream side. A second roller is connected downstream of the rolling rollers 3 and 4.
A conveyor 5 is provided, and a flexible fabric band 6 is provided above the conveyor 5 as a winding device for winding up the rolled divided fabric 1.

A small diameter shaft 7 is provided between the lower roller 4 and the second conveyor 5 in contact with or close to the lower roller 4. Further, a small diameter shaft 8 is provided in contact with or in close proximity to the downstream side of the upper roller 3.

Since the small diameter shaft 7 has the function of peeling off the divided fabric 1 stuck to the lower roller 4,
The smaller the surface area, the better. The maximum diameter is one-fourth of the length of the divided fabric 1 to generate a stable peeling effect.

The small diameter shaft 8 serves to peel off the divided fabric 1 stuck to the upper roller 3, and has the same effect as the shaft 7 on the roller 4.

The first conveyor 2, the second conveyor 5, the upper roller 3, and the lower roller 4 are driven by drive motors 9, 10, respectively.
11 and 12, and the small diameter shafts 7 and 8 are also driven by motors 13 and 14, and the upper roller 3 and lower roller 4 are moved closer to each other at a circumferential speed equal to or higher than the circumferential speed of the lower roller 4. It rotates in the same direction.

Next, to explain the winding up of the divided dough 1 in the embodiment, the divided dough 1 conveyed on the first conveyor 2 is supplied to the gap between the rolling rollers 3 and 4. When the divided dough 1 is transferred, it is stuck to the upper roller or the lower roller 4 because no hand flour or the like is used.

For example, if it sticks to the lower roller 4, if it touches the small diameter shaft 7 that rotates at high speed, the lower roller 4
The divided dough 1 is peeled off from the surface of the second conveyor 5.
It can be transferred to.

The divided fabric 1 adhering to the roller 4 comes into contact with the small diameter shaft 7 on the surface of the roller 4, but in this case, the circumferential speed of the small diameter shaft 7 is higher than the circumferential speed of the lower roller 4, and the diameter of the small diameter shaft 7 is If the length is less than 1/4 of the length of the divided fabric 1, the peeling effect will be noticeable.

If the conditions are not met, for example, small diameter shaft 7
If the peripheral speed is slow, the divided dough 1 will stagnate and stick on the surface of the lower roller 4, and if the surface area of the small diameter shaft 7 is large, the divided dough 1 will stick strongly to the small diameter shaft 7 and transfer to the second conveyor 5. This makes it impossible to do so.

Therefore, the smaller the diameter of the small-diameter shaft 7, the better, and the faster its rotation speed, the better the peeling effect will be. Further, the same effect can be obtained with respect to the peeling action by the small diameter shaft 8.

Next, since the second conveyor 5 is running faster than the upper roller 3 and the lower roller 4, the divided dough 1
When the is transferred to the second conveyor 5, at the crossing point between the rolling rollers 3, 4 and the second conveyor 5,
While the latter half of the dough 1 is still being held between the rolling rollers 3 and 4, it is pulled in the direction of travel so that the center line of the divided dough 1 can be aligned with the progress of the conveyor.

Therefore, it is possible to eliminate "rolling up from one side" which occurs when the center line of the divided dough 1 deviates from the conveyor traveling direction.

The surface of the dough on the second conveyor 5 is free from hand flour and is sticky, so when the dough piece 1 is rolled up on the second conveyor by the flexible cloth band 6, the wrapped surface is secure. It can be rolled up by adhesion to the surface, and "unwinding" does not occur.

The present invention eliminates the above-mentioned drawback of unstable rolling under adhesive conditions and ensures reliable conveyance.

(Effects) As explained above, in the present invention, the divided dough is fed in a sticky state to a rolling roller having a pair of rollers facing each other, and the dough stuck to the roller is peeled off by a small diameter shaft. This ensures that the fabric pieces are transferred to the downstream conveyor in the correct orientation.

In the present invention, unlike the conventional method, the dough can be rolled up without using hand flour or the like, so the divided dough can be sufficiently adhesive and unrolling can be avoided.

As explained above, it is possible to reduce the occurrence of ``unwinding'' and ``unwinding'' and to significantly reduce product loss due to winding mistakes compared to conventional winding methods.
