Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a cutting device for sheet-shaped dough, which cuts rice cake dough, confectionery dough, etc. rolled into a sheet while transporting the dough along the transport direction.

(Prior art) Conventionally, while transporting dough rolled into a sheet,
Various devices for cutting along the transport direction have been proposed.
It has been used (for example, Japanese Patent Publication No. 56-39857, Publication of Utility Model No. 42702 of 1982, Publication of Utility Model No. 42702 of 1981, Publication of Utility Model No. 61-58).

The dough rolled into a sheet is continuously transported by a conveyor belt, and during transport, it is continuously cut by a cutting roll installed on the conveyor belt or at the end of the conveyor belt, and unnecessary waste generated by cutting is removed. The part is designed to be discharged from the system.

(Problem to be solved by the invention) In the cutting device as described above, when the cutting roll cuts the fabric reliably, the cutting of the fabric and the discharge of unnecessary parts are performed smoothly. Problems have arisen when the blades become worn due to long-term use or the installation position of the cutting roll moves, resulting in incomplete cutting of the fabric. In other words, since the unnecessary parts generated by cutting are discharged by a discharge conveyor, the tension applied to the unnecessary parts is applied to the fabric that is not discharged by the discharge belt, that is, the product fabric, and the product fabric is dragged, damaging the shape of the product. There was a problem.

(Means for Solving the Problems) Therefore, in this invention, the fabric cut by the cutting roll is pressed by an annular elastic strip to prevent the product fabric from deforming.

That is, this invention is based on a sheet-shaped fabric cutting device in which a cutting roll is installed above a conveyor belt that conveys fabric rolled into a sheet. An annular elastic strip is installed opposite to the annular elastic strip, and the terminal end of the annular elastic strip faces the starting end of a delivery belt for separating and transporting a part of the cut fabric strip. This is a cutting device for sheet-like fabric.

The annular elastic strip is used when facing each strip of fabric produced by cutting with a cutting roll, and after cutting.
There are cases where it is opposed to the product fabric strip that will become the product. In addition, the above-mentioned delivery belt may be configured as a belt for transporting fabric strips that will become cutting waste, or as a belt for transporting fabric strips that will become product fabric, depending on the configuration of the production line. The selection will be made accordingly.

Incidentally, the annular elastic strip is constituted by a strip such as a string or band made of elastic synthetic resin such as a urethane belt.

(Function) According to the sheet-shaped fabric cutting device of this invention, the fabric strips formed by cutting with the cutting roll are sandwiched between at least the product fabric between the annular elastic strip and the conveyor belt, so that the fabric strips on the cut waste side are It is possible to avoid deformation of the product fabric by avoiding being dragged by the strips.

(Example) An example of this invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a horizontally installed conveyor belt, and rolling rolls 2, 2 are installed facing each other above the starting end side (left side in the figure) of the conveying belt 1. The dough 4 of the raw material 3 (for example, rice cake) rolled into a sheet shape at 2 and 2 can be sequentially transferred to the terminal end side by the conveyor belt 1. 5 in the figure is a guide roller.

A cutting roll 6 is installed in the middle of the conveyor belt 1 . As shown in FIG. 2, this cutting roll 6 has a structure in which cutting blades 7, 7 are provided on the circumferential surface, and the cutting roll 6 is installed in a positional relationship such that the edges of the cutting blades 7, 7 can substantially come into contact with the upper surface of the conveyor belt 1. has been done. When the fabric 4 passes between the cutting roll 6 and the conveyor belt 1, the fabric 4 is cut by the cutting blades 7, 7 to form a plurality of strip-shaped fabric strips 8a, 8b, 8c,... (see Fig. 3). It is starting to be divided into

Free rolls 9a, 9b, 9c are rotatably installed on both front and rear sides and above the cutting roll 6, and a plurality of annular elastic strips 10 made of urethane belts are attached to the free rolls 9a, 9b, 9c.
is attached, and the annular elastic strip 10 between the free rolls 9a and 9b is opposed to the conveyor belt 1. A plurality of annular elastic strips 10 are arranged on a free roll 9 at predetermined intervals so as to face each of the dough strips 8a, 8b, 8c, . . . formed by cutting with the cutting roll 6.
It is attached to a, 9b, and 9c.

Figure 3 shows a fabric strip 8 being transferred on the conveyor belt 1.
8b, 8c, . . . and the annular elastic strips 10, 10 facing each other.

A starting end side of a carry-out belt 11 provided diagonally at the terminal end side of the conveyor belt 1 faces behind the free roll 9b.

Note that the conveyor belt 1, rolling roll 2, cutting roll 6, and delivery belt 11 are each driven by a drive device (not shown) (independent or interlocked with each other), but the speed of each belt and the circumferential speed of each roll are constant. It goes without saying that

In the above embodiment, the dough 4 rolled by the rolling rolls 2, 2 is sequentially transferred to the cutting roll 6 side by the conveyor belt 1, and the dough 4 is rolled by the cutting roll 6 into a plurality of dough strips 8a, 8b, 8c. ...is cut off.
Fabric strips 8a, 8b, 8c... formed by cutting
is the part facing the starting end of the delivery belt 11,
The product fabric and the cutting waste are separated, one of which is discharged by the carry-out belt 11, and the other is transported as is to the terminal end by the conveyor belt 1. In Figure 3,
Assuming that a and a are product fabrics that will become products, and b and b are scraps generated by cutting, that is, cutting scraps, and the cutting scraps b and b are discharged by the carry-out belt 11, the product fabrics a and a are transferred to the conveyor belt 1. The cutting chips b, b are transferred to the terminal side while being placed on the conveyor belt 1.
It is transferred to the first side and discharged to the outside.

When the cut scraps b and b are transferred to the carry-out belt 11 and discharged, if the cutting blade 7 of the cutting roll 6 does not completely cut the product fabric a and the cut pieces b, the cut pieces b are transferred from the carry-out belt 11 to the cut pieces b. Although there is a risk that the applied tension will also extend to the product fabric a and cause the product fabric a to be pulled, the annular elastic strips 10, 10 work together with the conveyor belt 1 to clamp the cut fabric strips 8a, 8b, 8c... Therefore, it is possible to prevent the product material a from being dragged against the tension applied to the cutting waste b. Therefore, deformation of the product fabric a can also be prevented.

The same thing can be done even if the product material a is moved to the carry-out belt 11 and the cut waste b is transferred as is by the conveyor belt 1.

FIG. 4 shows another embodiment of this invention, in which the cutting roll 6 and the annular elastic strip 10 are installed apart from each other.

That is, a cutting roll 6 and an annular elastic strip 10 are sequentially installed in the intermediate portion of the conveyor belt 1 similar to the embodiment described above from the starting end side. The annular elastic strip 10 is attached to a free roll 12 arranged in parallel along the upper side of the conveyor belt 1.
a, 12b so that one side faces the conveyor belt 1. and freeroll 1
The starting end side of the obliquely disposed delivery belt 11 faces the outside of 2b.

In this embodiment, cut scraps b and b of the fabric strips 8a, 8b, 8c, etc. formed by cutting are transferred to the delivery belt 11, and the annular elastic strip 10 is It is provided to correspond only to

In this embodiment as well, when the fabric strips 8a, 8b, 8c... cut by the cutting roll 6 are transferred by the conveyor belt 1 and the cut scraps b, b are transferred to the carry-out belt 11, the tension applied to the cut scraps b, b is the product fabric a, a
However, since the product fabrics a and a are held between the annular elastic strip 10 and the conveyor belt 1, even if tension is applied from the cut waste side, the product fabrics will not be dragged. It also prevents deformation. In each of the above embodiments, the free rolls 9a, 9b, 9 to which the annular elastic strip 10 is attached are
c, 12a, 12b are provided with annular recessed grooves 13, 13 on the circumferential surface of the roll as shown in FIG. 5 so as to prevent meandering of the annular elastic strip 10. It is preferable that the annular elastic strips 10, 10 are fitted into the annular elastic strips 10, 10.

(Effect of the invention) As explained above, according to this invention, at least the product fabric side is pressed by the annular elastic strip in the fabric strip cut by the cutting roll, and the product fabric and cutting waste are separated. Therefore, there is an effect that deformation of the product fabric can be prevented and a predetermined product fabric can be efficiently produced from the strip-shaped fabric.
