Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the production of bread and baguettes and the like, so that the length of the rod-shaped bread dough can be automatically adjusted when the longitudinal direction of the rod-shaped bread dough being conveyed is rolled and stretched along the direction orthogonal to the conveying direction. Thus, the present invention relates to a method and an apparatus for rolling and stretching a rod-shaped bread dough that always obtains a rod-shaped bread dough having a certain length. More specifically, even if the length of the dough material that is continuously conveyed is not constant and there are variations such as mixing short dough, this rod-shaped dough material is used even if it is conveyed and supplied. It relates to making it possible to correct and roll to a desired bread dough length.
[0002]
[Prior art]
As an apparatus for rolling and stretching a rod-shaped bread dough, for example, Japanese Patent Application Laid-Open No. 61-181329 discloses a bread dough forming apparatus provided with automatic control means. This is because a plurality of article sensing devices are provided above the centering conveyor connected to the downstream side of the conveyor for conveying the rod-shaped bread dough, and the length of the rod-shaped bread dough is set to a predetermined length according to the number of operations of these sensing means. It is a rolling and stretching device that controls the distance between the press plate and the conveyor conveyor surface so as to be molded.
However, in the above-mentioned rolling and stretching apparatus, although the length of the rod-shaped bread dough is automatically adjusted, only the length of the rod-shaped bread dough after the rolling is measured, and the press plate is moved up and down according to the result. Therefore, there was a problem that the variation was large.
[0003]
In addition, the shape of the material for forming the rod-shaped bread dough is obtained by cutting a sheet-shaped dough into a rectangular shape and rolling it up to form a rod-shaped bread dough, which is further rolled and stretched to a desired length. It has been broken. In this case, if the weight and dimensions of the rectangular dough are constant, a rod-shaped bread dough having substantially the same dimensions can be obtained, so there is a slight error in the length of the rod-shaped dough continuously conveyed to the rolling member. In accordance with the detected size, the interval between the rolling member and the conveyor can be adjusted each time or appropriately to obtain a stretched rod-shaped bread dough having a certain size.
However, even in such a situation, the bar-shaped bread dough that deviates from the above-described range of some errors is conveyed due to various environmental conditions, for example, the width of the sheet-shaped dough prepared in advance is short. In such a case, the above-described means cannot obtain a stretched rod-shaped bread dough having a certain size. If the bar-like bread dough having a constant length can not be obtained, not only variations in the calcined final product is produced, for example, even when placed in a bread mold by bending them, variations occur in the form of the final product lowers the product quality Te.
[0004]
[Problems to be solved by the invention]
In the conventional technical means, there is a variation in the length of the rod-shaped bread dough that is continuously conveyed, and when a short one has been conveyed, the dough cannot be rolled to the desired dimensions. It is.
Further, when the rolling member has been adjusted corresponding to the dimensions of such a short dough, the dimensions of the rod-shaped bread dough that has already been supplied to the rolling member and is being rolled and drawn cannot obtain a desired value. There is a problem that it is stretched to a length longer than necessary.

Similarly, when the endless chain 133 is wound around the sprocket 107 of the vertical mechanism 83 and the sprocket 129 of the vertical mechanism 85 and the handle 111 is rotated, the vertical shaft 59 can move up and down. As can be understood from the above description, by operating the handle 109 and the handle 111 of the first interval adjusting devices 61 and 81 provided in the rolling and stretching device 7, the rolling unit 71 can be moved up and down. The distance between the rolling surface 52 formed by the endless belt 51 stretched on the portion 71 and the transport surface 1A of the transport conveyor 1 can be adjusted to a desired size. Further, by adjusting the first interval adjusting devices 61 and 81, the interval can be gradually decreased from the inlet side (upstream side of the rolling surface 52) toward the outlet side (downstream side of the rolling surface 52). It can be made larger or the same.
[0023]
Next, control of the upper and lower plates 35 by the second interval adjusting device 30 will be described based on FIGS. 1 and 2.
First, when the bar-shaped bread dough 13 passes between the sensor 5A and the sensor 5B of the detection device 5, the distances to the ends of the bar-shaped bread dough 13 are detected by these sensors. Based on these distances, the length L1 in the longitudinal direction of the rod-shaped bread dough 13 is calculated by the calculation process of the control device 9.
[0024]
Next, the rod-shaped bread dough 13 is conveyed by the conveyor 1 to the lower side of the rolling unit 71 of the rolling and stretching apparatus 7. At this time, the control device 9 controls the forward / backward movement of the pneumatic cylinder 33 according to the length L1 of the rod-shaped bread dough 13, and the upper / lower plate 35 moves up / down by the forward / backward movement. Pneumatic sheet re Nda 33 provided as described above is provided with at both ends alone retractable operable rod 33A and the rod 33B as shown in FIG. The amount of advance and retreat of these rods is provided as S1 on the rod 33A side and S2 on the rod 33B side (S2> S1). Therefore, the vertical amount S of the upper and lower plates 35 can be adjusted in four steps by a combination of the forward and backward movements of these rods.
[0025]
As an example, the relationship between the length L1 of the rod-shaped bread dough 13 and the vertical amount of the upper and lower plates 35 is as follows. When the length L1 of the rod-shaped bread dough 13 is equal to or longer than the predetermined length L of the rod-shaped bread dough 13, the vertical amount S of the upper and lower plates 35 is adjusted to “0” with each rod of the pneumatic cylinder 33 pulled. 7 (a)]. When the length L1 is less than the predetermined length L to LA (LA <L) or more, the rod 33A is pushed out, and the vertical amount S of the upper and lower plates 35 is adjusted to “S1” [FIG. 7 (b). ]. Further, when the length L1 is less than LA to LB (LB <LA) or more, the rod 33B is pushed out, and the vertical amount S of the upper and lower plates 35 is adjusted to “S2” [FIG. 7 (c)]. Further, when the length L1 is less than LB, all the rods are extruded, and the vertical amount S of the upper and lower plates 35 is adjusted to “S1 + S2” [FIG. 7 (d)]. By the vertical movement of the upper and lower plates 35, the distance between the rolling surface 52 </ b> A located at the entrance of the rolling surface 52 and the conveying surface 1 </ b> A of the conveyor 1 is adjusted independently from the rolling surface 52 </ b> B located below the plate 37. .
[0026]
The rod-shaped bread dough conveyed to the entrance portion of the rolling surface 52 is subjected to the rolling and stretching action by the rolling surface 52A adjusted based on the length L thereof. At this time, a shorter rod-shaped bread dough is subjected to stronger pressing and is stretched in the longitudinal direction. Furthermore, the rod-shaped bread dough is stretched in the longitudinal direction while rolling the lower surface of the rolling surface 52B.
[0027]
The length of the upper and lower plates 35 in the conveyance direction is set shorter than the distance between the front and rear of the rod-shaped bread dough 13 that is continuously conveyed. Accordingly, a plurality of bar-shaped bread doughs positioned below the rolling surface 52A do not enter at the same time, and each bar-shaped bread dough 13 has its length without affecting other bar-shaped bread doughs positioned below the rolling surface 52B. It is possible to receive a rolling and drawing action according to the above.
[0028]
As described above, in the first embodiment, the upper and lower plates that can move up and down are provided at the entrance of the rolling unit, but the present invention is not limited to this. For example, an upper and lower plate that can move up and down may be provided downstream of the fixed plate. Moreover, you may provide the plate fixed to the upstream and downstream of the up-and-down plate which can be moved up and down. At this time, the vertical movement of the upper and lower plates can be accurately controlled by providing the detection device 5 close to the upstream side of the upper and lower plates.
[0029]
In addition, by providing a plurality of upper and lower plates in a row, crushing of the rod-shaped bread dough can be caused to act a plurality of times, and rolling and stretching can be promoted and fine length adjustment can be performed.
[0030]
Further, instead of stretching one endless belt 51, a belt such as canvas cotton may be attached to the upper and lower plates and the lower surface of the plate in a detachable manner to form a rolling surface.
[0031]
Alternatively, the rolling surface may be formed by directly using the upper and lower plates and the plate as a rolling member without attaching a belt or the like. In this case, a plurality of shallow grooves may be formed on the upper and lower plates and the lower surface of the plate.
[0032]
Further, in order to operate the rolling unit 71 up and down and tiltable, the handle 109 of the first interval adjusting device 61 and the handle 111 of the first interval adjusting device 81 are used, but a motor is used instead of the handle. It is also possible to operate. At this time, it is also possible to detect the length in the longitudinal direction of the rolled bread-shaped dough 15 and automatically adjust the vertical height and inclination of the rolling unit 71 based on the detection result. Furthermore, it is also possible to appropriately correct the arithmetic expression for controlling the vertical amount of the upper and lower plates 35 that can move up and down based on the detection result.
[0033]
In the first embodiment, the handle 50 is used to circulate the endless belt 51. However, instead of the handle 50, a motor can be connected to the shaft 47, and the endless belt 51 is periodically attached. Alternatively, by continuously rotating and renewing the contact surface with the rod-shaped bread dough, the dough adhesion is suppressed, so that the monitoring work by manpower can be omitted and the production efficiency can be improved.
[0034]
In the first embodiment, in order to adjust the distance between the conveying surface 1A and the rolling surface 52A of the conveyor 1 independently from the rolling surface 52B, the upper and lower plates 35 are moved up and down using a pneumatic cylinder as a second spacing adjusting device. It moved. However, the device is not limited to the pneumatic cylinder as long as the device can adjust the upper and lower plates 35 to be movable up and down.
[0035]
In the first embodiment, the distance between the rolling surface 52B and the conveying surface 1A is adjusted so that the rolling surface 52B moves in parallel. However, the distance is adjusted by swinging the upper and lower plates with an arbitrary position as a fulcrum. May be.
[0036]
In the first embodiment, the rolling and stretching apparatus 7 is placed above the conveyor 1 provided horizontally. However, the horizontal limitation is not necessary. For example, dough is placed on a pair of opposed rollers. It is also possible to implement the present invention in a so-called generally well-known molder in which a dough roll forming device such as a curl net and a rolling and drawing device are provided below.
[0037]
In the first embodiment, the bread dough 11 has been described as a rectangular shape that is long in the transport direction. However, the bread dough 11 may be an oval shape, an oval shape, or a rod-shaped bread dough having a direction perpendicular to the transport direction as a longitudinal direction. If the bread dough is needed.
[0038]
【The invention's effect】
