DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the drawings.
A food dough (hereinafter referred to as dough) D1 such as confectionery, bread dough, etc. is transported, stretched and formed into a thin stretch dough D2 by the spreader 10 and transported downstream, and excess hand flour on the surface of the stretch dough D2 is handed. It is removed by the powder removing device 20, and on the downstream side thereof, the spread fabric D2 is arbitrarily moved in the left-right direction with respect to the traveling direction by the moving device 30, and is further conveyed to a downstream process.
[0006]
The extension device 10 is a known extension device, in which a plurality of conveyor belts 11 and 12 connected from upstream to downstream are provided, and a planetary roller mechanism 13 including a plurality of rollers provided with a predetermined gap is provided above the conveyor belts 11 and 12. It is. A hand flour device 14 is provided above the planetary roller mechanism 13 so as to spray hand flour on the surface of the spread fabric.
A hand dust removing device 20 is provided downstream of the spreader device 10. The hand powder removing device 20 supports the extended fabric D2 and conveys the belt-like belts 21A, 21B, the rotating brushes 23A, 23B, 23C for removing the hand powder on the surface of the conveyed fabric D2, and the removal. It consists of a suction nozzle 24 for hand powder. As shown in FIG. 2, the string-like belt 21A is provided by being fitted and stretched in the roller grooves of a plurality of rollers 22A, 22B, and 22C, and the string-like belt 21B is similarly provided with rollers 22C and 22D. , 22E are provided so as to be stretched. Therefore, the string-like belts 21A and 21B rotate integrally with the rollers by the rotation of these rollers, and convey the fabric D2. Of the above rollers, the roller 22E corresponds to a centering roller 31 described later.
[0007]
Rotating brushes 23A, 23B, and 23C are provided up and down at arbitrary positions in the section of the cord belts 21A and 21B. The rotating brush has a large number of brushes attached to the rotating shaft in the radial direction. When these rotate, the hand powder on the surface of the fabric D2 being conveyed can be removed.
Adjacent to the upstream side of the rotating brush, a suction nozzle 24 for hand powder removed by the brush is provided. Hand powder from the suction nozzle 24 is sucked by the action of a suction device (not shown).
[0008]
The moving device 30 will be described. The aligning roller 31 (22E) is supported by a drive shaft 32 for moving in the left-right direction with respect to the traveling direction of the dough. The drive shaft 32 is supported by the frame 37. The aligning roller 31 rotates freely with respect to the rotation direction. For the left and right direction, a male screw provided on a drive shaft 32 that supports the aligning roller 31 and a drive shaft are provided. A frame 37 provided with a female screw so as to support and mesh 32 is movable as a support portion.
Therefore, when the drive shaft 32 rotates by a predetermined amount, the mechanism moves to the left and right by the screw pitch. The drive shaft 32 is rotated by a predetermined amount by a motor 33.
[0009]
A support roller 34 that supports the dough D2 at a predetermined height is provided adjacent to the downstream of the aligning roller 31. The support roller 34 rotates at the same speed as the cord belts 21A and 21B and the alignment roller 31 so as to convey the fabric downstream. The support roller 34 uses a non-adhesive material such as a plastic material. Sensors 35 </ b> A and 35 </ b> B are installed at the left and right positions of the support roller 34. This sensor uses a photoelectric sensor as an example to measure the distance to the side edge of the fabric D2 that passes over the support roller 34. An arithmetic device 36 is provided for receiving a signal from the sensor 35 and sending an operation signal to the motor 33.
A conveyor 40 is provided downstream of the support roller 34 to continue to the subsequent process.
[0010]
Next, the alignment operation in the embodiment will be described. The cloth D2 that has passed through the hand dust removing device 20 and placed on the support roller 34 has its side edges detected by the sensors 35A and 35B, the distance is calculated by the calculation device 36, and the center C1 of the width of the cloth D2 Is calculated. When the arithmetic unit determines that this position is different from the center origin C for conveyance of the conveyance device, the aligning roller 31 corresponds to the direction of movement of the fabric in either of the left and right directions ( A signal for rotation by a predetermined amount is sent from the arithmetic unit to the motor 33 so as to move to the arrow S).
By continuously measuring the fabric side edges using the sensors 35A and 35B, the center C1 of the fabric and the transport center C of the transport device can be continuously matched. In FIG. 2, the fabric width is shown to be constant, but needless to say, the width of the conveyed fabric may not be uniform depending on the status of the fabric supplied to the spreader.
[0011]
In the present embodiment, since the side edge of the fabric is detected on the support roller 34 that rotates at the same speed as the alignment roller 31 provided close to the downstream of the alignment roller 31, the correct fabric is detected. Can be detected.
Unlike the above-described embodiment, it is possible to provide a support roller on the upstream side instead of providing the support roller on the downstream side of the alignment roller 31. In this case as well, the correct fabric side edge can be detected, as in the case where it is provided downstream.
[0012]
【The invention's effect】
According to the present invention, it is possible to convey the center of the fabric width so as to coincide with the center of the origin of the conveyance device, and it is possible to reduce the lost fabric in various molding operations and reduce the production cost. In addition, since the fabric alignment monitoring operation can be performed automatically, the manual operation can be reduced.
