Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for rolling up bread dough, etc.
The aim is to completely eliminate operational errors during high-speed molding and reduce production costs.

(Prior Art) Conventionally, in the production of croissants and bread rolls, the method of rolling up dough divided into predetermined sizes from one side and forming the dough is carried out using a flexible cloth band stationary on a conveyor that transports the dough, or a flexible cloth belt stationary on a conveyor that conveys the dough, or A belt moving in the opposite direction to the movement of the belt is placed close to the belt, and the cloth is rolled up in this close gap.

(Problems to be Solved by the Invention) In the method of the prior art described above, the winding effect is not all as expected, but "unwinding" and "rolling up from one side" occur due to inevitable causes, and both products The above-mentioned loss occurred by several percent, sometimes tens of percent, due to defective products.

The inevitable cause of this "unrolling" is that when dividing the dough or transporting the divided dough, flour, etc. is left on the dough to prevent it from sticking to other parts. Eliminating the use of flour eliminates the problem of unrolling, but this causes another processing problem that causes the dough to stick when dividing and transporting.

In addition, "rolling up 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 roll or croissant is not uniform. It does not become spindle-shaped, but becomes amorphous and loses its commercial value.

(Means and effects for solving the problems) The present invention aims to completely eliminate processing errors that frequently occur due to these reasons.

In the present invention, first, before the divided dough pieces enter the winding device, they are compressed by upper and lower rollers, and by rotating the upper and lower pressing rollers at a slower speed than the transport conveyor in the downstream winding device, Since the center line of the divided dough pieces could be aligned with the direction of movement of the conveyor, it was possible to prevent "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 cause additional loss. That's right.

To prevent this "unwinding", make sure that the dough always sticks to the lower roller of the above-mentioned upper and lower rollers, or the upper roller. A small diameter shaft installed close to or in contact with the roller rotates it in the same direction as the lower roller and at a higher speed than the lower roller to peel off the sticky fabric and feed it into the winding device.
In addition, the divided fabric stuck to the upper roller is rotated in the same direction as the upper roller at a faster circumferential speed than the upper roller using a small diameter shaft provided close to or in contact with the upper roller.
The dough that is stuck to the roller is peeled off and sent to a winding device, and the adhesive strength of one side of the divided dough is used to roll up the product without unwinding.

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

Between the lower roller 4 and the second conveyor 5,
A small diameter shaft 7 is provided close to or in contact with the lower roller 4. Since this small-diameter shaft 7 has the effect of peeling off the divided fabric 1 stuck to the lower roller 4, the smaller the surface area, the better. Its maximum diameter is divided fabric 1
A stable peeling effect is produced up to a quarter of the length.

The surface of the upper roller 3 is given an extremely smooth finish to prevent the rolled dough from sticking, or the surface of the roller is coated with hand flour or the like using a hand flour device 14, or the roller surface is coated with a special anti-adhesive agent.

The surface of the lower roller 4 should be roughened or
A large number of narrow grooves are cut in the dough, or a spraying device 8 or the like is provided to apply a sticky material such as water, so that the dough to be rolled becomes sticky.

The first conveyor 2, the second conveyor 5, the upper roller 3, and the lower roller 4 are driven by drive motors 9, 10, 11, and 12, respectively, and the small diameter shaft 7 is also driven by a motor 13.
The lower roller 4 is rotated in the same direction as the lower roller 4 at a circumferential speed higher than that of the lower roller 4.

FIG. 2 shows another embodiment, in which the vertical positions of the adhesive roller and the non-adhesive roller are reversed. That is, the surface of the upper roller 16 of the rolling roller provided downstream of the first conveyor 15 that conveys the divided dough 1 is formed into a surface to which the dough sticks, and the surface of the lower roller 17 is formed so that the dough adheres. Form on a non-stick surface. A second conveyor 18 is connected downstream of the rolling roller, as in the first embodiment.
A flexible fabric band 19 is provided above it as a winding device for rolling up the rolled divided fabric 1. A small diameter shaft 20 is provided between the upper roller 16 and the second conveyor 18 in close proximity to or in contact with the upper roller 16. 21 is a spraying device for adhering a sticky material such as water;
The conveyor 15, the second conveyor 18, the upper roller 16, and the lower roller 17 are driven by drive motors 22, 23, 24, and 25, respectively, and the small diameter shaft 20 is also driven by the motor 26, and the upper roller 16 in the same direction as the upper roller 16,
The same effect as the small diameter shaft 7 of the first embodiment is performed.

Further, FIG. 3 shows still another embodiment, in which the first conveyor 27 for conveying the divided dough 1 is passed over a roller 28 below the rolling roller,
The divided dough 1 is rolled through the gap between the upper roller 29 and the first conveyor 27, and the surface of the first conveyor 27 is formed into a surface to which the dough sticks, and the surface of the upper roller 29 is formed so that the dough does not stick. Form the surface like this. The first conveyor 27 and the second conveyor 3 are stretched over the lower rollers 28.
The second embodiment is the same as the first embodiment except that a small-diameter shaft 31 is provided close to or in contact with the first conveyor 27 during the first embodiment. In addition, in FIG. 3, 32 is a spraying device for adhering an adhesive material such as water, and 33 is a flexible fabric band for winding up the rolled divided fabric 1.

Next, to explain the winding action of the divided dough 1 in the first embodiment, the divided dough 1 conveyed on the first conveyor 2 is supplied to the gap between rolling rollers 3 and 4, but the upper roller 3 is is smooth and has been treated with non-adhesive treatment, and the lower roller has been treated with adhesive treatment in the opposite way to the upper roller 3, so the rolling roller divides the dough 1.
When it is rolled, the divided dough 1 always sticks to the lower roller 4 and is transported in the stuck state.

Next, since the divided dough 1 is adhered to the lower roller 4, when it touches the small diameter shaft 7 rotating at high speed, it is peeled off from the surface of the lower roller 4 and transferred to the second conveyor 5.

Divided dough 1 stuck to lower roller 4
contacts the small diameter shaft 7 on the surface of the lower roller 4, but in this case, the circumferential speed of the small diameter shaft 7 is faster than the circumferential speed of the lower roller 4, and the diameter of the small diameter shaft 7 is equal to the length of the divided fabric 1. If the diameter is less than one quarter, the peeling effect will be noticeable. If this condition is not met, for example, if the circumferential speed of the small diameter shaft 7 is slower than the lower roller 4, the divided fabric 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 strongly adhere to the small diameter shaft 7 and will not be able to transfer to the second conveyor 5.

Therefore, the smaller the diameter of the small-diameter shaft 7, the better, and the faster its rotational speed, the better the peeling effect.

Since the surface of the fabric in the part peeled off from the lower roller 4 has adhesive properties, the divided fabric 1 is
When rolled up with flexible cloth etc. 6 on the conveyor,
The wrapped surface will definitely stick and "unwinding" will not occur.

Also, since the second conveyor 5 is running faster than the upper roller 3 and the lower roller 4, the center line of the divided dough 1 is aligned with the conveyor at the crossing point between the rolling rollers 3, 4 and the second conveyor 5. can be matched to the progression of

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.

Further, as in the second embodiment, the upper roller 16
The same effect can also be obtained by making the divided fabric 1 stick to the top and not the bottom roller 17.

The present invention eliminates such rolling with unstable adhesion conditions and forcibly causes the material to adhere to the lower roller or the upper roller, thereby ensuring reliable conveyance.

(Effects of the Invention) As explained above, the present invention provides an advantageous effect by opposing the non-adhesive upper roller and the adhesive lower roller or the adhesive upper roller and the non-adhesive lower roller. , the divided dough supplied to this rolling roller is always firmly adhered to the lower roller or the upper roller, and is peeled off by a small diameter shaft, so that the peeled divided dough is oriented in the correct direction. This ensures that the material is transferred to the downstream conveyor.

Therefore, problems such as "unwinding" or "rolling up too far" do not occur, and compared to conventional winding methods, product loss due to winding mistakes can be eliminated.
