Description

The present invention relates to a rest conveyor for conveying a dough ball obtained by rolling and forming a fermented dough such as bread dough, a rolled dough wound up from a sheet-like dough, and a dough forming system including the rest conveyor.

In the bread manufacturing process, there is a process in which the dough ball or the rolled-up dough is shaped and then rested for a certain period of time. As a device for carrying out this process, in a shaping machine for shaping a wound fabric by rolling between a dough feeding conveyor and a rolling plate, a plurality of kneading conveyors having different transfer directions are laid below the dough feeding conveyor. There is a shaping machine with a Nekashi conveyor (Patent Document 1).

Japanese Utility Model Publication No. 55-108887

In the shaping machine with a skewer conveyor described in Patent Document 1, each thread conveyor is continuously driven. However, when simultaneously shaping a plurality of groups of wound fabrics along the width direction orthogonal to the transport direction, it may be disturbed because they cannot be arranged on the rows along the width direction. When these hoisting fabrics are transported by a caulking conveyor and dropped and transferred onto the caulking conveyors located sequentially below, the group of hoisting fabrics are further disturbed by the rolling of the hoisting fabrics. In addition, when the dough balls are transported by such a multi-stage kneading conveyor, a drop in the timing of dropping due to the shape of the dough balls and adhesion to the transport surface of the conveyor occurs, and the group of dough pieces is aligned in the width direction. There is a problem that it cannot be transported together.

This dough ball is rounded and shaped from a large dough or a small dough cut from a continuous sheet-like dough to the required size and weight. A certain dough skin is formed, but at the bottom of the dough ball, there is a gathered portion of dough skin called a rounded butt. This aggregated portion exhibits a surface state that is different from other fabric skins such as wrinkles and high tackiness. Therefore, in the case of bread products such as buns, the position of this gathering portion is positioned at the bottom, and in the case of roll-up products, it is positioned on the top surface of the dough that has been extended in the form of a sheet. It must be hidden inside and not exposed to the surface of the final product. For this reason, it is desired to supply the dough balls to the subsequent process so that the aggregate portion is located on the upper surface or the lower surface of the dough balls.

When the dough ball is transferred from the upper level conveyor to the lower level conveyor, the dough ball is turned upside down. However, the appropriateness of this upside down is due to the relationship between the size and weight of the dough ball and the distance between the upper and lower conveyors, that is, the drop, so it is properly reversed if the drop (interval) of the upper and lower conveyors is constant There is a problem that the permissible range such as the shape of the dough ball is limited to a narrow range.

The present invention is a rest conveyor that conveys a dough while resting, and includes a carry-in conveyor that carries a plurality of doughs in a row, and is movable in the front-rear direction and the up-down direction, and a group of the carry-on conveyor on the carry-in conveyor A transfer conveyor for transferring the dough onto the following multi-stage conveyor, a plurality of conveyors arranged in a multi-stage up and down, and a multi-stage conveyor for conveying the group of doughs, with the conveyance directions of each conveyor alternately arranged, The apparatus includes a carry-out conveyor that receives the group of fabrics carried out from a multi-stage conveyor and carries them out of the rest conveyor. The multi-stage conveyor transfers the group of doughs from at least the uppermost conveyor to the lower-stage conveyor. In this case, the lower conveyor is temporarily stopped and intermittently moved, and a group of fabrics is transferred from the lowermost conveyor to the carry-out conveyor. And wherein said discharge conveyor to so as to intermittently transport operation is temporarily stopped controllably be provided when it is transferred.

Further, the rest conveyor is provided so that the upstream end side of each conveyor of the multi-stage conveyor can swing in the vertical direction with the upstream end side of each conveyor as a fulcrum. It is characterized by having an elevating device that adjusts to the above.

Moreover, it is the said rest conveyor, Comprising: The raising stop position of the said transfer conveyor was provided so that adjustment was possible to the up-down direction with respect to the uppermost conveyor of the said multistage conveyor.

Further, in the rest conveyor, each conveyor of the multi-stage conveyor is supported by a frame of the rest conveyor, and each conveyor includes a driving roller, a conveyor frame, a tip roller, and a conveyor belt, and the conveyor frame, the tip roller, and The conveyor belt is easily attached to and detached from the frame, one end of the rotating shaft of the drive roller is attached to the frame, and the other end of the rotating shaft is attached to and detached from the frame via a bearing member. It is easily provided, and on the other side of the rotating shaft, a support bracket is provided below the roller portion of the driving roller.

The dough forming system includes the rest conveyor, and includes a rounding machine capable of forming the gathering portion S of the dough skin on the bottom of the dough on the upstream side of the rest conveyor.

The dough forming system includes the rest conveyor, and includes a hoisting device for hoisting the dough on the downstream side of the rest conveyor.

According to the present invention, when the dough drops and is transferred to the lower conveyor, the dough is received while the conveyance of the lower conveyor is temporarily stopped. Even when the timing at which each dough falls on the lower conveyor in the group of doughs is shifted, it can be transferred to the lower conveyor in a state aligned in the width direction, thereby solving the above-described conventional problems. be able to.

In addition, since the interval between the upper and lower conveyors of the multi-stage conveyor can be adjusted all at once, the drop of the cloth can be adjusted appropriately according to various conditions such as the size of the cloth, and the conventional problems described above can be solved. Can do.

In addition, since the rising stop position of the transfer conveyor for transferring the dough onto the multi-stage conveyor can be adjusted, the dough can be inverted and dropped from the transfer conveyor or can be left still. In particular, the gathered portion of the dough skin formed by rounding can be supplied to the subsequent process so as to be positioned on the upper surface or the lower surface of the dough ball.

On the downstream side of the rounding device 3, specifically the alignment conveyor 11, a rest conveyor 5 is provided continuously. The rest conveyor 5 is a conveying device for resting the dough ball W2 formed by the rounding device 3 while conveying the ball for a required time. The rest conveyor 5 includes a carry-in conveyor 12, a transfer conveyor 13, a multistage conveyor 14, and a carry-out conveyor 15 inside the frame 6.

The carry-in conveyor 12 is arranged in series on the downstream side of the aligning conveyor 11, and sequentially conveys a plurality of dough balls W <b> 2 that are sequentially conveyed at predetermined intervals and intermittently. In the present embodiment, the description will be made assuming that 10 groups are provided.

A transfer conveyor 13 is provided on the left side of the carry-in conveyor 12 (the lower side in the drawing of FIG. 2). The transfer conveyor 13 is a transfer device that receives a group of dough balls W2 arranged in a line at equal intervals on the carry-in conveyor 12 and moves them onto a multi-stage conveyor 14 arranged on the right side of the carry-in conveyor 12. The transfer conveyor 13 is a belt conveyor in which a belt-shaped conveyor belt 20 is wound around a driving roller 17, a front end plate 18, and a rear end roller 19. A return roller 21 is provided outside the conveyor belt 20 so as to face the rear end roller 19. Both ends in the longitudinal direction of the conveyor belt 20 are detachably engaged with and fixed to the driving roller 17. Further, the drive roller 17 is interlocked and connected to a drive motor M1 (not shown), and reciprocally rotates by the forward / reverse rotation drive of the drive motor M1 so that the conveying surface (upper surface) of the conveyor belt 20 is forward and backward (arrows). Y is reciprocated in the front-rear direction along the horizontal direction.

Further, the transfer conveyor 13 is provided such that the entire apparatus can reciprocate back and forth along the Y direction, and can be moved up and down along the direction indicated by the arrow Z. The transfer conveyor 13 is supported between the support plates 22A and 22B facing each other as a whole. Further, the support plates 22A and 22B on both sides are movably supported by opposing lift plates 24A and 24B arranged on the outer side (left and right sides in FIG. 2) thereof. One support plate 22A has two guide rollers 26 attached to the upper and lower portions thereof, and sandwiches the upper and lower ends of the corresponding lift plate 24A between the two upper and lower opposing guide rollers 26. The other support plate 22B also sandwiches the upper and lower ends of the corresponding lift plate 24B in the same manner as the one support plate 22A.

A mechanism that reciprocates before and after the transfer conveyor 13 will be described. A drive motor M2 (not shown) is attached inside one support plate 22A, and a pinion 27A is attached to the output shaft of the drive motor M2 outside the support plate 22A. Further, a rack 28A is attached horizontally inside the one lifting plate 24A along the Y direction in the longitudinal direction. The pinion 27A and the rack 28A are engaged with each other. Further, an idle gear 30A attached to one end of the rotating shaft 29 is engaged with the pinion 27A. An idle gear 30 </ b> B is attached to the other end of the rotating shaft 29. Further, on the outside of the other support plate 22B, a pinion 27B rotatably attached to a support shaft (not shown) meshes with an idle gear 30B. Further, a rack 28B is attached to the inside of the other lift plate 24B and meshes with the pinion 22B. With these drive mechanisms, the transfer conveyor 13 can reciprocate in the horizontal direction with respect to the lift plates 24A and 24B by rotating the output shaft of the drive motor M2 forward and backward.

Next, a mechanism for moving the transfer conveyor 13 up and down will be described. Two guide rails 31 arranged in the vertical direction are attached to the frame 6 of the rest conveyor 5 in parallel. Two guide rollers 32 are attached to both ends of the elevating plate 24A in the horizontal direction, and two sets of guide rollers 32 sandwich the outside of the guide rail 31 (left and right sides in FIG. 6).

A drive motor M3 is attached to the lower portion of the frame 6, and a drive pulley 33A is attached to the output shaft of the drive motor M3. Further, a driven pulley 34 </ b> A is attached to the upper portion of the frame 6. An endless timing belt 35A is wound around a driving pulley 33A and a driven pulley 34A arranged above and below. The timing belt 35A is coupled to the elevating plate 24A via a connecting member 36A.

Therefore, when the output shaft of the drive motor M3 is rotated forward and backward, the lifting plates 35A and 35B are reciprocated in the vertical direction to move the transfer conveyor 13 up and down. The front and rear and upper and lower movement positions of the transfer device 13 can be adjusted and controlled within a movable range.

The operation of the transfer conveyor 13 will be described with reference to FIG. For convenience of explanation, a state where the transfer conveyor 13 waits at a position farthest from the carry-in conveyor 12 on the side of the carry-in conveyor 12 is defined as an initial position (see FIG. 4A). When the group of dough balls W2 are stopped in a row on the carry-in conveyor 12, the transfer conveyor 13 moves the drive roller 17 while moving horizontally (referred to as advance) in the direction of the arrow P1 (Y direction). By rotating counterclockwise as indicated by arrow R1, the conveying surface of the conveyor belt 20 is moved in the direction opposite to the arrow P1 (counter-Y direction). And the conveyor front-end | tip part of the transfer conveyor 13 enters between the lower surface of the dough ball W2 and the conveyance surface (upper surface) of the carry-in conveyor 12, and picks up and receives the dough ball W2 on the upper surface of the conveyor belt 20 (FIG. 4 ( b)). At this time, by making the magnitude of the moving speed of the transfer conveyor 13 in the horizontal direction the same as the magnitude of the moving speed of the conveying surface of the conveyor belt 20 in the transfer conveyor 13, the conveyor for the dough ball W2 The conveyor belt 20 (the tip portion of the transfer conveyor 13) can enter the lower surface of the dough ball W2 without moving the belt conveyance surface. The moving speed before and after the transfer conveyor 13 and the rotation speed of the drive roller 17 can be adjusted individually, and when it is difficult to transfer to the conveyor tip due to a small dough ball W2, the conveying surface of the conveyor belt 20 It is also possible to cope with this by setting the movement speed of the above larger than the above.

The transfer device 13 that scoops up the dough ball W2 rises in the direction of the arrow P2 (Z direction) shown in FIG. 4B, and the transfer surface position of the first conveyor 41 provided at the top of the multistage conveyor 14 Stop at a higher position (see FIG. 4C). And it advances to the horizontal direction shown by arrow P3, and stops when the conveyor front-end | tip part of the transfer conveyor 13 is located above the conveyance surface of the 1st conveyor 41 (refer FIG.4 (d)). Then, while horizontally moving (referred to as reverse) in the direction indicated by the arrow P4 (referred to as the reverse Y direction), the drive roller 17 is rotated clockwise as indicated by the arrow R2, and the conveying surface of the conveyor belt 20 is opposite to the arrow P4. Move in (Y direction). At this time, if the magnitude of the moving speed of the transfer conveyor 13 in the horizontal direction and the magnitude of the moving speed of the conveying surface of the conveyor belt 20 in the transfer conveyor 13 are the same, the dough ball W2 moves in the horizontal direction. Instead, the transfer conveyor 13 is pulled out from below the dough ball W2, and the dough ball W2 is inverted and dropped from the tip of the transfer conveyor 13 and transferred onto the transport surface of the first conveyor 41. The dough ball W2 is turned upside down and the gathering portion S is positioned on the upper surface (see FIG. 4E). The driving roller 17 of the transfer conveyor 13 is rotated in the clockwise direction indicated by the arrow R2, and the conveying surface of the conveyor belt 20 is moved in the direction opposite to the arrow P4 (Y direction) to transfer the dough ball W2 to the transfer conveyor 13. After being dropped, the transfer conveyor 13 may be retracted in the P4 direction.

The transfer conveyor 13 moves backward to the same horizontal position as the initial position, descends in the direction indicated by the arrow P5 (anti-Z direction), returns to the initial position, and waits until the next group of dough balls W2 are aligned. .

Next, the operation of the transfer conveyor 13 will be described with reference to FIG. 5 (a) is the same as FIG. 4 (a), and FIG. 5 (b) is the same operation as FIG. 4 (b). FIG. 5C shows a state in which the transfer conveyor 13 has received the dough ball W2 and stopped at the raised position. This lift stop position is lower than the position shown in FIG. 4C, and is slightly upward so that the lower surface position of the conveyor tip portion of the transfer conveyor 13 does not interfere with the transport surface position of the first conveyor 41. positioned. At this rising stop position, the transfer conveyor 13 advances in the P3 direction and stops when the conveyor tip portion of the transfer conveyor 13 is positioned above the transport surface of the first conveyor 41 (see FIG. 5D). . Then, as described with reference to FIG. 4D, the drive roller 17 is rotated in the clockwise direction indicated by the arrow R2 while retreating in the direction indicated by the arrow P4 (counter-Y direction), and the conveying surface of the conveyor belt 20 is indicated by the arrow. Move in the direction opposite to P4 (Y direction). At this time, the transfer ball 13 is pulled out from below the dough ball W2 without moving the dough ball W2 in the horizontal direction, and the transfer ball 13 is transferred from the tip of the transfer conveyor 13 onto the transport surface of the first conveyor 41. It will be posted. In the case where there is almost no drop between the conveyor tip of the transfer conveyor 13 and the transport surface of the first conveyor 41, the dough ball W2 is not inverted upside down, and the gathering portion S is moved while being located on the lower surface of the dough ball W2. (See FIG. 5E).

The transfer conveyor 13 moves backward to the same horizontal position as the initial position, descends in the direction indicated by the arrow P5 (anti-Z direction), returns to the initial position, and waits until the next group of dough balls W2 are aligned. . As can be understood from these explanations, when the dough ball W2 is transferred from the transfer conveyor 13 to the first conveyor 41 by adjusting the rising stop position of the transfer conveyor 13 with respect to the first conveyor 41, the dough ball It is possible to transfer without reversing the upper and lower surface positions of W2 or without reversing.

Carry out to 16.

By repeating this operation, the dough balls W2 supplied from the transfer conveyor 13 to the first conveyor 41 are arranged on the second conveyor 42 to the fifth conveyor 45 at equal intervals and are intermittently conveyed. In addition, when transferring from the upper conveyor to the lower conveyor, the dough is rested while being repeatedly inverted and dropped. Finally, the dough is inverted and dropped from the tip of the conveyor of the sixth conveyor 46 to the transfer surface of the carry-out conveyor 15. Reprinted. In addition, it is also possible to drive the conveyance of the 1st conveyor 41 and / or the 6th conveyor 46 intermittently.

An alignment conveyor 16 is connected downstream from the rest conveyor 5, specifically, downstream from the carry-out conveyor 15. The alignment conveyor 16 performs a conveyance operation in synchronization with the conveyance operation of the carry-out conveyor 15 and receives a group of dough balls W2, and then starts an intermittent conveyance. A hoisting device 7 is connected downstream of the alignment conveyor 16. The hoisting device 7 includes a carry-in conveyor 81, a gauge roller 83, a shaping conveyor 85, a curl net 87, and a rolling plate 89. The carry-in conveyor 81 is connected to the downstream side of the alignment conveyor 16, and the dough ball W <b> 2 is intermittently supplied from the alignment conveyor 16. A gauge roller 83 is continuously provided on the downstream side of the carry-in conveyor 81. The gauge roller 83 is composed of a pair of rotating rollers arranged facing each other in the vertical direction, and rotates in opposite directions so as to rotate in the transport direction X on the facing surfaces. Further, the gaps between the rollers 83A and 83B are provided so as to be adjustable. By passing through the gauge roller 83, the dough ball W2 is spread on the flaky dough sheet W3. On the downstream side of the gauge roller 83, a shaping conveyor 85, which is a belt conveyor, is continuously provided. Further, above the shaping conveyor 85, a curl net 87 is provided on the upstream side, and a rolling plate 89 is provided on the downstream side thereof. The dough sheet W3 is conveyed to the shaping conveyor 85, wound up by the interdigital curl net 87, and then wound up strongly by the rolling plate, and the thin rod-like rolled-up cloth W4 is shaped. At this time, it is desirable that the gathering portion S of the dough balls W2 supplied to the hoisting device 7 is located on the upper surface side of the dough balls W2.

Also, for example, when manufacturing products such as buns, heat treatment such as an array device that arranges in multiple rows and multiple rows on a display plate without performing secondary molding such as winding the dough ball W2, or a proofing or oven heat treatment It is also possible to provide the device on the downstream side of the rest conveyor 5. In this case, it is desirable to position the gathering part S on the lower surface side (bottom part) of the dough ball W2 conveyed from the carry-out conveyor 15 of the rest conveyor 5. In this rest conveyor 5, since the rising stop position of the transfer device 13 can be adjusted, when transferring the dough ball W <b> 2 onto the multistage conveyor 14, the dough ball W <b> 2 on the transfer device 13 is inverted and dropped, Alternatively, the transfer can be selectively adjusted without inversion. In addition, in the multi-stage conveyor 14, in order to transfer the dough ball W2 from the upper conveyor to the lower conveyor, the upper and lower surfaces of the dough ball W2 can be alternately reversed because the interval (drop) between the conveyors is adjustable. It is possible to accurately position the gathering portion S on the upper surface side or the lower surface side.

Furthermore, the above-mentioned reversal adjustment of the dough ball W2 is possible by providing a rounding machine that can form the gathering portion S of the dough skin on the bottom of the dough ball W2 on the upstream side of the rest conveyor 5.

The description of the rest conveyor according to the embodiment of the present invention is generally as described above. However, the present invention is not limited thereto, and various modifications can be made within the scope of the claims. For example, although the dough supplied to the rest conveyor 5 has been described as the dough ball W2, the dough can be transported while resting by using the dough in the rolled-up dough W4 obtained by applying a rolling pressure to the dough. . In this case, it is desirable that the roll dough is pressed slightly flat in order to prevent rolling on the conveyor when it is dropped and transferred to the lower conveyor.
