The nozzle 43 and the detector S2 are provided. It is composed. The nozzle 43 is connected to an air compression device such as a liquid tank and a compressor (not shown) via an on-off valve such as an electromagnetic valve. The detector S2 is provided in the vicinity of the upstream side of the nozzle 43, and is a sensor that senses the passage of the conveyed rod-shaped bread dough B. [0013]
The pulverizer 50 disperses particles such as sesame on the conveying surface 11 intermittently, and constitutes a hopper 53 and a detector S3. The hopper 53 is provided with a lattice-like hole at the bottom and distributes particulates through the hole. Since the hopper 53 is a known device, detailed description thereof is omitted. The detector S3 is a sensor that is provided in the vicinity of the downstream side of the hopper 53 and senses that the bar-shaped bread dough B has passed below the hopper 53.
[0014]
The winding device 60 is provided to roll the rod-shaped bread dough B on the transport surface 11, and a metal net 63 is suspended from above the transport conveyor 10.
[0015]

The shutter unit 73 includes a shutter plate 73A that is fixed obliquely downward along the transport direction A from the front end side of the transport conveyor 10, and a swingable shutter plate 73B that faces the shutter plate 73A. is doing.
[0016]
The roller unit 75 includes two rollers of the same diameter, an upstream roller 75A located upstream with respect to the conveyance direction A and a downstream roller 75B located downstream thereof, and the interval between them is a stick-shaped bread dough. It is provided so that it can be adjusted slightly smaller than the thickness of B. The rotation axes of the upstream roller 75A and the downstream roller 75B are provided so as to be orthogonal to the transport direction A and parallel to the upper surface 83A of the top plate 83 transported by the transport conveyor 80 described later. Further, the downstream roller 75B is provided at a position slightly higher than the upstream roller 75A with respect to the top plate 83, and an upper and lower step is provided on the rotation shafts of the two rollers 75A and 75B. Further, when the upstream roller 75A and the downstream roller 75B rotate inward from each other, the peripheral speed V1 of the outer peripheral surface of the upstream roller 75A rotates faster than the peripheral speed V2 of the outer peripheral surface of the downstream roller 75B. It is linked to a drive motor (not shown). Further, a peeling roller 77 is provided below the downstream roller 75B so as to rotate in the same direction as the downstream roller 75B. Further, a detector S4 for sensing the presence or absence of the rod-shaped bread dough B received by the shutter unit 73 is provided on the side of the shutter unit 73 (see FIG. 4).
[0017]
The transport conveyor 80 is a known chain conveyor that is configured with a pair of endless hook chains 87 with hooks 85 attached at regular intervals. A flat top plate 83 is placed between the hooks 85. It is the conveying apparatus which conveys.
[0018]
Next, the operation of the transport apparatus 1 configured as described above will be described with reference to FIGS. The rod-shaped bread dough B that has been rolled up in advance from a rectangular or oval dough sheet is transported in the transport direction A by the transport belt 13, and passes below the compaction device 20, so that the compaction plate 23 and the transport surface 11 The length is reduced and the thickness is reduced while being rolled. The rod-shaped bread dough B that has passed through the rolling device 20 has a difference in the degree of extension and the amount of rolling between the center portion of the dough and the end portion of the dough, so that both end portions have advanced in the traveling direction from the center portion. It becomes the shape of the letter.
[0019]
The rod-shaped bread dough B bent in a substantially square shape is further transported by the transport belt 13 (see FIG. 3A). The rod-shaped bread dough B comes into contact with the roller 33 immediately after being detected by the detector S1 provided in the stopping / clamping device 30. The roller 33 rotates in the direction R1 in which the roller outer peripheral surface is opposite to the transport direction A on the inner side facing the transport surface 11, and the peripheral speed rotates at the same or slightly higher speed than the transport speed of the transport belt 13. ing. The rod-shaped bread dough B is supported by the roller 33 and the conveyance surface 11, further receives driving from the roller 33 and the conveyance surface 11, and starts rotating at that position. The rod-shaped bread dough B bent in a substantially U shape by this rotation is almost released from the twisting stress remaining in the bread dough, and is corrected to a straight bar-shaped bread dough B (see FIG. 3B).
[0020]
After a predetermined time has elapsed since the detector S1 sensed the rod-shaped bread dough B, the roller 33 rotates in the direction R2 opposite to the rotation direction R1. At this time, the peripheral speed of the roller 33 rotates so as to be slightly faster than the transport speed of the transport belt 13. Then, the rod-shaped bread dough B that has been stationaryly rotated and corrected to be linear is sandwiched between the roller 33 and the transport surface 11 and is transported without rolling while being slightly crushed. Further, due to the difference between the circumferential speed of the roller 33 and the conveyance speed of the conveyance belt 13, the rod-shaped bread dough B is pressed in the direction of the conveyance belt 13 having a low speed and is in close contact with the conveyance surface 11 (see FIG. 3C). Therefore, since the stick-shaped bread dough B does not roll on the conveyance surface 11 and is conveyed in close contact with the conveyance surface 11, irregular rolling on the conveyance surface that occurs at the time of molding with the conventional locking member occurs. As a result, there was no disorder in the spacing between the rod-shaped bread doughs B that were sequentially conveyed.
[0021]
Moreover, the cross-section of the rod-shaped bread dough B that has passed through the roller 33 is slightly flattened, and a bottom surface that contacts the transport surface 11 is formed (see FIG. 3D). Further, since the rod-shaped bread dough B is in close contact with the transport surface 11 as described above, it is suppressed from being bent again by the twisting stress remaining inside the bread dough. The roller 33 rotates in the direction R1 again after the rod-shaped bread dough B has passed, and waits for the next rod-shaped bread dough B to be conveyed.
[0022]
The flattened bread dough B is further conveyed, and its passage is sensed by the detector S2 provided in the spraying device 40. Water is sprayed from the nozzle 43 onto the surface of the rod-shaped bread dough B for a predetermined time in response to the command of the sensing signal. Furthermore, the rod-shaped bread dough B is conveyed, passes under the hopper 53 of the granulator 50, and is detected by the detector S3. Then, in accordance with a sensing signal command from the detector S3, a granular material such as sesame is distributed from the hopper 53 to the conveying surface 11 on the upstream side of the rod-shaped bread dough for a predetermined time. Thereafter, the rod-shaped bread dough B passes through the winding device 60. At this time, the rod-shaped bread dough B is conveyed while rolling on the conveying surface 11 by the resistance of the net 63. And the granular material distributed on the conveyance surface 11 adheres to the surface.
[0023]
Next, the rod-shaped bread dough B to which the granular material is attached falls from the front end of the conveyor 10 and is temporarily held by the shutter portion 73 of the transfer device 70. When the detector S4 provided on the side of the shutter portion 73 senses the rod-shaped bread dough B, the shutter plate 53B of the shutter portion 53 swings around its upper end so as to open the shutter, and the rod-shaped bread dough B is It falls on the roller part 75 provided below. Then, the shutter plate 53B swings back to close the shutter again. The temporary holding of the rod-shaped bread dough B by the shutter portion 73 is to prevent the plurality of rod-shaped bread dough B from staying at the roller portion 75.
[0024]
The two rollers 75A and 75B of the roller unit 75 wait for the rod-shaped bread dough B to fall in a state where the rotation is stopped. The dropped stick-shaped bread dough B is temporarily left between the upstream roller 75A and the downstream roller 75B, and the disturbance such as bending due to the fall is corrected (see FIG. 4A). The upstream roller 75A and the downstream roller 75B start to rotate inward after a lapse of a predetermined time after the detector S4 senses the rod-shaped bread dough B, and the peripheral speed V1 of the upstream roller 75A is on the downstream side. It rotates faster than the peripheral speed V2 of the roller 75B. Then, the rod-shaped bread dough B is fed while being slightly pinched between the two rollers 75A and 75B, and passes through the upstream roller 75A side so as to be bent toward the downstream roller 75B having a low peripheral speed. (See FIG. 4 (B)), and peeled from the downstream roller 75B by the rotation of the peeling shaft 77 provided near the lower side of the downstream roller 75B (see FIG. 4 (C)).
[0025]
At this time, a pulling force along the discharge direction C is applied to the inside of the rod-shaped bread dough B. The force relaxes the torsional stress remaining inside the rod-shaped bread dough B, so that the bending of the rod-shaped bread dough B in the subsequent process is suppressed.
[0026]
Further, as described above, the upstream roller 75A and the downstream side 75B are provided with steps on their rotation shafts. Furthermore, a difference is provided in the peripheral speeds of the two rollers 75A and 75B. Thereby, the rod-shaped bread dough B passing between the two rollers 75A and 75B is discharged in the direction C inclined with respect to the vertical direction. Then, the rod-shaped bread dough B is transferred to the top plate 83 so that the long axis of the cross section flattened in a substantially oval shape is in the horizontal direction (see FIG. 4D).
[0027]
The top plate 83 on which the rod-shaped bread dough B is placed moves by a predetermined distance as the hook chain 87 of the conveyor 80 moves, and waits at that position until the next rod-shaped bread dough B is placed. The hook chain 87 is provided so as to be driven after the upstream rollers 75A and 75B have rotated and stopped for a set time. The top plate 83 is placed and transported with a plurality of stick-shaped bread dough B while repeating the movement and stop, and the moving speed is adjusted and set according to the number of times of movement per unit time (synonymous with the number of times of stick-shaped bread dough B is transferred). , It gets faster as the number increases. As described above, since the rod-like bread dough B that has passed between the upstream rollers 75A and 75B is flattened, rolling due to movement and stop is suppressed, and the interval between the rod-like bread dough B transferred to the top plate 83 is not disturbed. It is transported stably.
[0028]
The top plate 83 is transported to the fermentation chamber by another transport conveyor provided continuously with the transport conveyor 80, and the placed bread dough B is subjected to secondary fermentation. Each bar-shaped bread dough B is transferred from the top plate 83 to the endless conveyor belt of the tunnel oven and baked by a known depanner device.
[0029]
The conveying device 1 according to the embodiment of the present invention is generally as described above, but the configuration can be changed within the scope of the claims. For example, the two rollers 75 </ b> A and 75 </ b> B configured in the roller unit 75 of the transfer device 70 can be changed. The two rollers 75A and 75B described above use the same diameter roller, and the downstream roller 75B located on the downstream side is provided at a level slightly higher than the upstream roller 75A located on the upstream side. ing. That is, the upper and lower steps are provided on the rotation axis of the roller. Further, the description has been made such that the peripheral speed V1 of the upstream roller 75A rotates at a speed higher than the peripheral speed V2 of the downstream roller 75B. However, it is also possible to provide a difference in the peripheral speed of the rollers by setting the diameter of the upstream roller larger than the diameter of the downstream roller and rotating at the same rotational speed. Moreover, even if it rotates by making the peripheral speed of those outer peripheral surfaces the same, it is also possible to pass the rod-shaped bread dough B so that it may be bent downstream.
[0030]
Further, when the rod-shaped bread dough B is transferred from the roller unit 75 to the conveying device positioned below, the top plate 83 of the conveyer 80 is moved in the conveying direction at a speed at which the rod-shaped bread dough does not roll on the transfer surface. When moving, the two rollers 75A and 75B do not need to have a step, and the bread dough B whose cross section is flattened to a substantially oval shape is transferred so that its long axis is in the horizontal direction. The
[0031]
Further, the conveying device located below the roller unit 75 is not limited to the conveying conveyor 80 that conveys the top plate 83, but may be a belt conveyor that is wound around an endless belt, and its drive is moved intermittently. However, it is possible to transfer the rod-shaped bread dough without rolling even if it is continuously moved at a low speed.
[0032]
Further, when the spray device 40 is not configured in the transport device 1, it is not necessary to provide the peeling shaft 77 located below the downstream roller 75B, and the stick-shaped bread dough B does not stick to the downstream roller 75B and is lowered by its own weight. It is possible to fall into.
[0033]
In the above-described embodiment, the case where the rod-shaped bread dough B is conveyed in one row has been described. However, the present invention is not limited to this, and the present invention can also be implemented in a multi-row state in which a plurality of rows are arranged in the transverse direction with respect to the conveying direction A. In addition, when individual rod-shaped bread dough B is conveyed with some disturbance in the conveying direction A, it is possible to align the horizontal direction with the stopping / clamping device 30 and the transfer device 70 and supply them to the next process. it can.
[0034]
【The invention's effect】
As can be understood from the above description, the present invention is a transfer device for transferring a rod-shaped bread dough conveyed by a conveyance conveyor to a conveyance device positioned below the conveyance conveyor, the conveyance conveyor and the conveyance device. A means for providing an upstream roller and a downstream roller in parallel and intermittently rotatable was adopted. The rod-shaped bread dough passes while being pressed between the two rollers, and is flattened in a substantially oval shape in cross-section and discharged and transferred to the transport device. By applying a pulling force in the direction and relieving the twisting stress remaining inside the bread dough, it becomes possible to suppress the bending of the rod-like bread dough in the subsequent process.
[0035]
In addition, by providing the rotating shaft of the downstream roller above the rotating shaft of the upstream roller, and further by making the peripheral speed of the downstream roller slower than the peripheral speed of the upstream roller, It has become possible to stably transfer to the transport device so that the long axis of the step surface is in the horizontal direction. When the conveying device is intermittently driven, the rolling of the rod-shaped bread dough is suppressed, and it becomes possible to prevent the interval between the rod-shaped bread doughs from being disturbed.
