DETAILED DESCRIPTION OF THE INVENTION
As conceptually shown in FIG. 1, the food dough spreading apparatus 1 according to the embodiment of the present invention has conveying speeds V1, V2, and V3 for conveying food dough 3 such as confectionery dough and bread dough as shown in FIG. In order to extend the food dough 3 conveyed in the downstream direction (arrow A direction) from the upstream side by a plurality of conveying conveyors 5, 7, 9 that are connected in series. An extension conveyor 13 provided with a plurality of extension rollers 11 in an endless manner is disposed above the respective conveyors 5, 7, 9.
[0009]
Even if the plurality of conveyors 5, 7, and 9 are configured to be individually rotated by individual control motors, a difference in conveyance speed is generated between the conveyors 5, 7, and 9 through an appropriate speed change mechanism. Thus, the configuration may be such that each of the conveyors 5, 7, and 9 is rotationally driven by a single motor. In short, it is only necessary that the conveyance speed (V) of the downstream conveyor is larger. That is, in this example, the relationship is V3>V2> V1. The configuration for connecting a plurality of transfer conveyors 5, 7 and 9 in series and increasing the transfer speed toward the downstream side is a configuration that individually rotates as described above, a motor or the like via an appropriate speed change mechanism, etc. Since various configurations such as appropriate interlocking connection with the driving source can be employed, detailed description of the configuration for rotationally driving each of the conveyors 5, 7 and 9 is omitted.
[0010]
The extension conveyor 13 is supported by a roller shaft 19 rotatably supported at both ends by a bearing 17 (see FIG. 2) attached to a pair of endless rotating bodies 15A and 15B at appropriate intervals such as an endless chain and an endless belt. It is the structure which supported the said extension roller 11 rotatably via the bearing 21, Comprising: From the appropriate upstream position of the conveyance termination side of the 1st conveyance conveyor 5 to the appropriate downstream position of the conveyance start end side of the 3rd conveyance conveyor 9 It is provided over.
[0011]
The appropriate position of each of the endless rotating bodies 15A and 15B is guided and supported so as not to be loose by an appropriate guide member (not shown) such as a chain guide provided in the apparatus main body (not shown). The bearings 17 provided in the endless rotating bodies 15A and 15B are guided and supported by roller guides 23 (see FIG. 2) provided in the apparatus main body.
[0012]
In the extension conveyor 13, the extension roller 11 located in the extension action region for extending the food dough 3 being transferred by the first, second, and third transfer conveyors 5, 7, and 9 and each of the transfer conveyors The distances (gap) t between the top surfaces of 5, 7, and 9 are set to t1, t2, and t3, respectively, and the distances t1, t2, and t3 have a relationship of t1>t2> t3. That is, the interval between the downstream conveyor and the extension roller 11 is set to be gradually smaller than the interval between the upstream conveyor 5 and the extension roller 11 of the extension conveyor 13.
[0013]
As the configuration in which the gaps t1, t2, and t3 are gradually reduced, the first, second, and third transfer conveyors may be used even in the configuration in which there is a step between the first, second, and third transfer conveyors 5, 7, and 9. 5, 7, 9 may be arranged on the inclined surface, or relatively, the roller guide portion on the lower side of the roller guide 23 may be stepped or inclined so that the downstream side is lowered. It ’s good.
[0014]
The point is that the interval between the conveyor and the extension conveyor is gradually narrowed so that the food dough 3 conveyed by the first, second, and third conveyors 5, 7, and 9 is gradually thinned. Is. The extension conveyor 13 travels and rotates at a speed higher than the conveyance speed V3 of the third downstream conveyor 9, and this type of extension conveyor 13 is configured to rotate and move. Since it is well known and well known, illustration and description of the details of its configuration are omitted.
[0015]
Extending rollers on both sides of the first, second, and third conveyors 5, 7, and 9 for contacting and pressing and extending the food dough 3 on the conveyors 5, 7, and 9 in the extending action region. A rotation imparting means 25 for imparting rotation to 11 is provided.
[0016]
More specifically, on both sides of the first conveyor 5, rolling guides 27 that contact the vicinity of both ends of the extension roller 11 in the extension conveyor 13 that press-contacts the food dough 3 on the first conveyor 5 are arranged in parallel. Is provided. The rolling guide 27 is composed of a member having a large friction such as hard rubber, for example, and the rolling roller 11 is pressed from the position where the rolling roller 11 is pressed against the food dough 3 on the first conveyor 5 by the rotation of the stretching conveyor 13. The first conveyor 13 is provided long over the conveyance end.
[0017]
Therefore, when the extension roller 11 moves in the same direction as the conveyance direction of the first conveyor 5 due to the rotation of the extension conveyor 13, both ends of the extension roller 11 come into contact with the rolling guide 27, causing rotation at the rotation speed R1. Will roll. Then, the food dough 3 on the first conveyor 5 is extended to the thickness of the gap t1 between the conveyor 5 and the extension conveyor 13.
[0018]
At this time, the extension roller 11 in the extension conveyor 13 is rotated by rolling on the rolling guide 27 provided fixed at a fixed position of the apparatus main body, so that the rotation speed R1 of the extension roller 11 is For example, since the extension roller 11 contacts the first conveyor 5 and the rotational speed generated by the speed difference between the extension conveyor 13 and the first conveyor 5 is different, the contact relationship between the extension roller 11 and the food dough 3 is It is not a pure rolling contact that does not cause slip, but a relative slip occurs between the spreading roller 11 and the food dough 3, and tends to cause wrinkles and scratches on the upper surface of the food dough 3. However, even if wrinkles and scratches are generated here, the wrinkles and scratches are not a problem because they are further extended at the positions of the second and third conveyors 7 and 9.
[0019]
On both sides of the second conveyor 7, end rolls, belts, and the like having the same length as that of the conveyor 7 are provided to rotate the extending rollers 11 that extend the food dough 3 on the conveyor 7. One rotation transmission member 29 is provided in parallel. Further, on both sides of the third conveyor 9, in order to give rotation to the extending roller 11 that extends the food dough 3 on the third conveyor 9, the vicinity of the conveyance start end of the conveyor 9 is appropriately extended to the downstream range. A second rotation transmission member 31 similar to the first rotation transmission member 29 is provided. The first rotation transmission member 29 is wound around the first drive pulley 33 and the first driven pulley 35 rotated by the first control motor M1, and the second rotation transmission member 31 is rotated by the second control motor M2. A second driven pulley 37 that is rotated and a second driven pulley 39 that is rotatably provided coaxially with the first driven pulley 35 are wound around.
[0020]
The first and second drive pulleys 33 and 37 and the first and second driven pulleys 35 and 39 have the same diameter, and the first rotation transmission member 29 is connected to the second transport conveyor 7 by the first control motor M1. The second rotation transmission member 31 is rotated at the same speed in the same direction as the third transport conveyor 9 by the second control motor M2.
[0021]
When the vicinity of both ends of the extension roller 11 in the extension conveyor 13 moves from a position corresponding to the first conveyor 5 to a position corresponding to the second conveyor 7, the rolling guide 27 moves onto the first rotation transmission member 29. The extension roller 11 moves and rotates at the rotation speed R2 due to the speed difference between the extension conveyor 13 and the first rotation transmission member 29. When moving from the position corresponding to the second transfer conveyor 7 to the position corresponding to the third transfer conveyor 9, the vicinity of both ends of the extension roller 11 moves from the first rotation transmission member 29 onto the second rotation transmission member 31. The extension roller 11 is rotated at the rotation speed R3 due to the speed difference between the extension conveyor 13 and the second rotation transmission member 31.
[0022]
With the above configuration, when the food dough 3 extended to the thickness t1 on the first conveyor 5 is transferred from the first conveyor 5 to the second conveyor 7, the first conveyor 5 and the second conveyor 5 are transported. The food dough 3 is stretched further thinly on the second transport conveyor 7 while being stretched by the speed difference with the conveyor 7 and the interval t2 between the second transport conveyor 7 and the extension conveyor 13 becomes narrower. .
[0023]
The vicinity of both ends of the extension roller 11 at a position corresponding to the second conveyor 7 is in contact with the first rotation transmission member 29, and the rotation speed R2 of the extension roller 11 due to the difference in rotation speed between the first rotation transmission member 29 and the extension conveyor 13 Cause rotation. At this time, since the first rotation transmission member 29 and the second conveyor 7 are rotating in the same direction at the same speed, the extending roller 11 rolls with the rotation of the pure roller contact with the second conveyor 7 without slipping. It becomes an aspect. Further, the first rotation transmission member 29 has an endless belt shape, and the extending roller 11 is always in contact with the first rotation transmission member 29 and does not cause uneven rotation. Accordingly, the food dough 3 on the second conveyor 7 and the spreading roller 11 are brought into pure rolling contact without slipping, and the food dough 3 can be spread without causing wrinkles or scratches on the upper surface of the food dough 3. .
[0024]
When the food dough 3 extended to the thickness t2 on the second conveyor 7 is transferred from the second conveyor 7 to the third conveyor 9, the second and third conveyors 7, 9 The food dough 3 is further thinned by being stretched by the speed difference and by further reducing the interval t3 with the spread conveyor 13 on the third transport conveyor 9. When the food dough 3 is further thinly extended on the third conveyor 9, the extension roller 11 in the extension conveyor 13 contacts the second rotation transmission member 31 that rotates at the same speed in the same direction as the third conveyor 9. Therefore, on the third transport conveyor 9 as well, as in the second transport conveyor 7, there is a non-slip pure rolling contact between the food dough 3 and the spreading roller 11 of the spreading conveyor 13, and the food dough 3 The upper surface is not wrinkled or scratched.
[0025]
As already understood, in this example, the food dough 3 transferred by the transport conveyor and the extending roller 11 in the extending conveyor 13 maintain a pure rolling contact relationship without slipping and perform the extending action of the food dough 3. As a result, the spreading action can be performed without causing wrinkles or scratches on the food dough 3. Here, when it is better to slightly change the rotation speed of the first and second rotation transmission members 29 and 31 from the rotation speed of the second and third conveyors 7 and 9 depending on the physical properties of the food dough 3 and the like. Can be easily handled by controlling the rotational speeds of the first and second control motors M1, M2 by a control device.

Is. The endless belt is exemplified as the first and second rotation transmission members 29 and 31. However, in the case where the extension roller 11 has a sprocket having the same diameter as that of the extension roller 11, the sprocket is used. It is also possible to adopt a chain structure that can be engaged and disengaged. Furthermore, instead of the belt-like rotation transmitting members 29 and 31, a large number of small-diameter rollers that are rotated in the same direction by a gear train or the like may be provided in parallel in the transport direction of the transport conveyor.
[0027]
