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 carrying a dough ball with such a multi-stage kneading conveyor, there is a shift in the fall timing due to the shape of the dough ball and adhesion to the carrying surface of the conveyor, and a group of dough balls is aligned in the width direction. There is a problem that it cannot be transported together. Further, the dough balls are sequentially dropped on each stage, so that the dough balls are damaged, and irregular impact marks remain on the surface of the dough balls.

A food conveyance processing apparatus 5 according to an embodiment of the present invention and a dough forming system 1 including the food conveyance processing apparatus 5 will be described with reference to FIGS. Here, the case where bread dough is shape | molded as a foodstuff is demonstrated. The dough forming system 1 includes a dough piece forming device 2, a rounding device 3, a food conveyance processing device 5, a hoisting device 7, and a control device 31 that controls the operation of each device. The dough piece forming apparatus 2 forms a dough continuous from a large dough mass, cuts a dough piece W1 having a required weight from the dough band into a rectangular shape, and intermittently takes a required distance in the conveying direction indicated by an arrow X. They are transported one by one. It should be noted that this time interval for intermittent conveyance is not necessarily constant and may vary.

A rounding device 3 is connected to the downstream side (left side in FIG. 1) of the dough piece forming device 2. In the rounding device 3, the longitudinal direction of the forming plate 10 facing the horizontal direction above the transport conveyor 9 is arranged substantially along the transport direction X of the transport conveyor 9. The molded plate 10 is formed such that the facing distance is relatively narrow on the lower side and wider on the upper side. In addition, the opposing molded plates 10 are provided so as to be able to approach and separate from each other, and when they approach each other, horizontally rotate in the same direction with a phase difference of 180 degrees so as to move in opposite directions along the transport direction X. It is possible (see the arrow in FIG. 2). When the opposing molding plates 10 move closer to each other, the molding plate 10 presses the fabric from both sides to raise the fabric and torsion is applied in the horizontal direction so that the surface of the fabric has a tension. The dough is rounded and molded while forming.

The rectangular dough piece W1 is intermittently sent between the opposing forming plates 10 by a predetermined distance by the conveyor 9 and rounded once or multiple times by the opposing forming plate 10 when the conveyance is stopped. Is done. Then, it is rounded again at the next stop position. By repeating this rounding process a plurality of times, the dough piece W1 is rounded into the dough ball W2. The rounded and formed dough ball W2 has a dough skin gathering portion S formed on the bottom surface (lower surface). In addition, as an apparatus which can form the gathering part S of dough epidermis on the bottom face of the dough ball W2, the apparatus described in Japanese Patent No. 3054766 filed by the present applicant can also be exemplified.

On the downstream side of the conveyor 9, an alignment conveyor 11 that connects the food conveyor 5 is provided. The aligning conveyor 11 is a conveying device for receiving the dough balls W2 conveyed at a long distance interval on the conveying conveyor 9, changing them to a short distance interval, and supplying them to the food conveying apparatus 5. The alignment conveyor 11 is provided with a two-speed conveyor 11A and a continuous conveyor 11B. The second speed conveyor 11A receives the dough ball W2 from the transfer conveyor 9 in a high speed state, shifts to the same low speed state as the continuous conveyor 11B, and transfers the dough ball W2 to the continuous conveyor 11B. The continuous conveyor 11B is continuously driven and driven at a required speed.

On the downstream side of the rounding device 3, specifically the alignment conveyor 11, a food conveyance processing device 5 is continuously provided. This food conveyance processing device 5 is a device that performs various processes while conveying the dough ball W2 formed by the rounding device 3 for a required time. The food conveyance processing apparatus 5 includes a carry-in conveyor 12, a first transfer conveyor 13, a multistage conveyor 14, a second transfer conveyor 23, and a carry-out conveyor 15 inside the frame 6. Here, the food conveyance processing apparatus 5 is demonstrated as a rest conveyor for resting the dough ball W2 formed by rounding.

The carry-in conveyor 12 is a belt conveyor that is arranged in series on the downstream side of the alignment conveyor 11 and that intermittently conveys a plurality of dough balls W2 that are sequentially conveyed so as to be placed at a predetermined distance. In the present embodiment, ten dough balls W2 will be described as one group. Moreover, the carry-in conveyor 12 is arrange | positioned under the rear end part (upstream side edge part) of the 6th process conveyor 46 in the lowest stage of the multistage conveyor 14 mentioned later (refer FIG. 3).

The first transfer conveyor 13 is provided on the left side (lower side in the drawing of FIG. 2) of the carry-in conveyor 12. The first transfer conveyor 13 receives a group of dough balls W2 arranged in a line at equal intervals on the carry-in conveyor 12, and is placed on each processing conveyor (41 to 46) of the multi-stage conveyor 14 disposed above the carry-in conveyor 12. It is the transfer device which supplies to. The first transfer conveyor 13 is a belt conveyor in which a belt-shaped conveyor belt 20 is wound around a conveyor frame 17, a front end plate 18 and a rear end roller 19. The conveyor belt 20 is attached to a joint plate 21 provided at both ends thereof so as to be capable of reciprocating with respect to the conveyor frame 17 and formed in an endless shape. Between the joint plate 21 and the conveyor frame 17, a direct acting actuator AC1 such as an electric linear rail that reciprocally rotates the conveyor belt 20 is attached. The transport surface (upper surface) of the conveyor belt 20 reciprocates in the forward direction and the reverse direction (indicated by the arrow Y in the front-rear direction along the horizontal direction) by reciprocating the slider of the actuator AC1.

The first transfer conveyor 13 can be reciprocated back and forth along the Y direction, and can be moved up and down along the direction indicated by the arrow Z. The first transfer conveyor 13 is supported by the base plate 24. The base plate 24 is supported by the elevating frame 22 via the actuator AC2. By reciprocating the slider of the actuator AC2 in the horizontal direction, the first transfer conveyor 13 can reciprocate back and forth.

The elevating frame 22 is attached to a direct acting actuator AC3. The actuator AC3 is, for example, a ball screw type linear rail, and includes a slider that is movably screwed to a ball screw interlocked with the control motor M1, such as a servo motor, and the output shaft of the control motor M1. The slider is reciprocated in the up and down direction by rotating in a forward and reverse direction. By attaching the elevating frame 22 to the slider, the elevating frame 22 and the first transfer conveyor 13 are provided so that they can be raised and lowered according to the rotational drive of the control motor M1.

Next, the basic operation of the first transfer conveyor 13 will be described with reference to FIG. For convenience of explanation, a state where the first 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). Starting from when a group of dough balls W2 are stopped in a row on the carry-in conveyor 12, the actuator AC2 is driven to move the first transfer conveyor 13 horizontally in the direction of the arrow P1 (Y direction) (referred to as advance). At the same time, the actuator AC1 is driven to move the joint plate 21 in the direction opposite to the arrow P1 (counter-Y direction), and the conveyor belt 20 is rotated counterclockwise. And the conveyor front-end | tip part 13A of the 1st 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 20A of the conveyor belt 20. (See FIG. 4 (b)).

At this time, by making the magnitude of the moving speed in the Y direction of the transfer conveyor 13 and the magnitude of the moving speed in the anti-Y direction of the conveying surface 20A of the conveyor belt 20 in the transfer conveyor 13 equal, The transport surface 20A of the conveyor belt 20 does not move with respect to the ball W2, and the tip portion of the conveyor belt 20 (tip portion 13A of the first transfer conveyor 13) can enter the lower surface of the dough ball W2. In addition, the moving speed to the front and rear of the first transfer conveyor 13 and the rotation speed of the conveyor belt 20 can be individually adjusted, and when it is difficult to transfer to the front end of the conveyor due to a small dough ball W2, the conveyor belt It is also possible to cope with this by setting the moving speed of the 20 conveying surfaces 20A larger than the above. In addition, the placement position of the center of the dough ball W <b> 2 with respect to the tip of the first transfer conveyor 13 can be set according to the size of the food to be placed and the interval of each food on the multistage conveyor 14.

The first transfer conveyor 13 that scoops up the dough ball W2 moves back in the direction of the arrow P2 shown in FIG. 4B (counter Y direction) and returns to the initial position (see FIG. 4C). Here, the process until the first transfer conveyor 13 picks up the dough ball W2 from the starting point and returns to the initial position is referred to as a transfer process, and this time is referred to as a transfer process time TA. And it raises to the direction (Z direction) of the arrow P3, and stops in the position higher than the conveyance surface position of one of the processing conveyors selected among the processing conveyors 41 thru | or 46 with which the multistage conveyor 14 was equipped (FIG. 4). (See (d)). Here, the process from rising from the initial position to stopping is referred to as an ascending process, and this time is referred to as an ascending process time TB. And it stops for the required time at the raised position. Here, the ascending position stop process is called, and this time is called ascending position stopping process time TC. Then, it advances to the horizontal direction shown by arrow P4, and stops when the conveyor front-end | tip part 13A of the 1st transfer conveyor 13 is located above the conveyance surface of the 1st process conveyor 41 (refer FIG.4 (e)). Note that when the first transfer conveyor 13 scoops up the dough ball W2 and moves backward in the anti-Y direction, it is possible to superimpose an operation that moves upward in the Z direction in the initial stage of the upward movement. Thus, interference between the next dough ball W2 conveyed from the alignment conveyor 11 side and the first transfer conveyor 13 can be suppressed, and the overall processing speed can be increased.

The first transfer conveyor 13 moves the joint plate 21 in the direction of the arrow Y with respect to the conveyor plate 17 while horizontally moving (referred to as retreating) in the direction indicated by the arrow P5 (opposite Y direction). The 20 conveying surfaces 20A are moved in the direction opposite to the arrow P5 (Y direction), and the conveyor belt 20 is rotated clockwise. At this time, if the magnitude of the movement speed in the anti-Y direction of the transfer conveyor 13 and the magnitude of the movement speed in the Y direction of the conveying surface 20A of the conveyor belt 20 in the transfer conveyor 13 are the same, the dough ball W2 Does not move in the horizontal direction, the first transfer conveyor 13 is pulled out from below the dough ball W2, and the dough ball W2 falls from the tip portion 13A of the first transfer conveyor 13 and the corresponding conveyor surface of the processing conveyor Reprinted on top. The first transfer conveyor 13 moves backward to the same horizontal position as the initial position (see FIG. 4F). Here, the process until the first transfer conveyor 13 moves forward and the retreat is completed is referred to as a transfer process, and this time is referred to as a transfer process time TD.

The first transfer conveyor 13 descends in the direction indicated by the arrow P6 (counter Z direction), returns to the initial position, and stops. Here, this is referred to as a descent process, and this time is referred to as a descent process time TE. The first transfer conveyor 13 waits until the next group of dough balls W2 are aligned at the initial position. Here, it is referred to as a standby process, and this time is referred to as a standby process time TF. This series of steps is defined as one cycle. This series of steps is repeated in order from the uppermost first processing conveyor 41 to the lowermost sixth processing conveyor 46 of the multistage conveyor 14, which will be described later, and by repeating again from the uppermost stage, a group of dough balls W2 is placed on each processing conveyor. Can be supplied.

The first transfer conveyor 13 according to the present embodiment controls the operation so that the transfer process time TA and the transfer process time TD are the same in each of the above processes. However, the ascending process time TB of the first transfer conveyor 13 varies due to the distance (height) from the initial position to the corresponding position from the processing conveyors 41 to 46 of the multistage conveyor 14. That is, the rising process time TB to the first processing conveyor 41 is the longest, and the rising process time TB to the sixth processing conveyor 46 is the shortest.

Therefore, the total time required for the transfer process, the lift process, the lift position stop process, and the transfer process, that is, the first transfer device 13 receives the dough ball W2 on the carry-in conveyor 12, and the selected processing conveyor (41 to 41). 16) The ascending position stop process time TC is controlled to a time corresponding to the ascending process time TB so that the required time during the upper supply is constant. That is, even when the dough ball W2 is supplied to any processing conveyor, the total time required for the ascending process and the ascending position stopping process is controlled to be constant. Note that the ascending process time TB can be set based on an empirical rule. By setting the ascending process time TB in advance in the control device 31, the corresponding ascending position stop time TC is controlled to be calculated by the arithmetic processing device 33. Also good.

As described above, the time required for the first transfer conveyor 13 to receive the dough ball W2 on the carry-in conveyor 12 and supply the dough ball W2 on the selected processing conveyor (41 to 16) is constant. As a result, the distance between the first group of dough balls W2 supplied to the previous processing conveyor and the next group of dough balls W2 supplied to the next processing conveyor becomes substantially constant, and a second transfer conveyor described later. When the group of dough balls W2 are sequentially received from the downstream end side of the processing conveyor, a sufficient time interval can be maintained, and the operation of the second transfer conveyor 23 can be stabilized.

The multi-stage conveyor 14 is configured by a six-stage belt conveyor of the first processing conveyor 41 to the sixth processing conveyor 46 from above. The configuration of these processing conveyors 41 to 46 is the most common. Further, the conveying direction of these processing conveyors is the Y direction (upward in FIG. 2, rightward in FIG. 5). Moreover, the conveyor length of each processing conveyor 41 thru | or 46 is the same, and the space | interval of the upper and lower sides is arrange | positioned uniformly.

The configuration of the first processing conveyor 41 will be described. The first processing conveyor 41 includes a rear end roller 51, a driving roller 52 as a front end roller, a conveyor frame 53, and an endless conveyor belt 59. The drive roller 52 is rotatably supported by the frame 6. More specifically, a sprocket 47 is attached to one end (right side in FIG. 8A) of the rotating shaft 52B of the drive roller 52, and is linked to the control motor M2 via a power transmission mechanism 48 by a chain. Yes. An encoder 39 is linked to the output shaft of the control motor M2 through a power transmission mechanism 37 of a gear train. The encoder 39 transmits a signal associated with position information of each group of dough balls W2 supplied to each processing conveyor on each processing conveyor to the control device 31.

The other end (left side in FIG. 8A) of the rotation shaft 52 </ b> B of the drive roller 52 is pivotally supported by the bearing member 49. The bearing member 49 is detachably locked to a bracket FL attached to the frame 6. In this engagement mechanism, an engagement member 50 formed by a screw member attached to the bracket FL is inserted into and engaged with a dart-shaped engagement hole 49A formed in the bearing member 49. Further, inside the bracket FL, there is a support bracket 38 that supports the end of the roller portion 52A of the drive roller 52 when the bearing member 49 is removed from the rotation shaft 51B of the drive roller 52 (see FIG. 8A). It is attached. When the driving roller 52 is supported by the bearing member 49, the support bracket 38 is attached at a position that opens a slight gap with respect to the roller portion 52A. When the conveyor belt 59 is attached to and detached from the drive roller 52, the conveyor belt 59 can be inserted and removed from between the drive roller 52 and the support bracket 38.

The rear end roller 51 is detachably supported by an L-shaped groove 57 formed in the bracket BR and the bracket BL attached to the frame 6. The conveyor belt 59 is wound around the rear end roller 51, the conveyor frame 53 and the driving roller 52. The rotating shaft 51B of the rear end roller 51 protruding outward from the groove 57 is configured to be pushed toward the upstream side opposite to the transport direction Y by the toggle clamp 58. The conveyor belt 59 can be strengthened or loosened by operating the toggle clamp 58.

The conveyor frame 53 includes side frames 54 on both sides in the width direction of the first conveyor 41 (left and right in FIG. 2). One side frame 54 is detachably engaged with the bracket BR and the bracket FR attached to the frame 6. The other side frame 54 is detachably engaged with a bracket BL and a bracket FL attached to the frame 6. A plurality of span frames 55 are engaged between both side frames 54 (see FIG. 8B). The span frame 55 is a member bent into a U-shaped cross section, and notches 55 </ b> A formed at both ends thereof are engaged with the groove portions 54 </ b> A of the side frame 54.

As can be understood from the above description, the configuration of the first processing conveyor 41 other than the driving roller 52 can be easily attached to and detached from the dough processing apparatus 5 without using a tool such as a spanner. Further, the removed components such as the conveyor belt 59 can be easily cleaned, which is excellent in hygiene management.

The second processing conveyor 42 to the sixth processing conveyor 46 have the same configuration as the first processing conveyor 41. The sprocket 47 of the first processing conveyor 41 to the sprocket 47 of the sixth processing conveyor 46 are linked and connected to the control motor M2 via the power transmission mechanism 48 so as to rotate in the same direction. The first processing conveyor 41 to the sixth processing conveyor 46 transport the dough ball W2 at a constant speed from the upstream side (supply side) to the downstream side (discharge side) in the Y direction at a constant transport speed. . This conveyance speed is calculated by the arithmetic processing unit 33 by setting the control unit 31 with the time for conveying the dough ball W2 on each processing conveyor.

If the transfer position of the dough ball W2 supplied from the first transfer conveyor 13 to the upstream end side of each processing conveyor is G1, the dough ball W2 is processed after a lapse of a required time (for example, 30 minutes). It is received by a second transfer conveyor 23 described later on the downstream end side of the conveyor. This receiving position is assumed to be G2. The encoder 39 sends a signal to the control device 31 when the first transfer conveyor 13 transfers the dough ball W2 to the transfer position G1. The control device 31 receives the transfer time and the number of the processing conveyor to the arithmetic processing device 33, and calculates the time when the second transfer device 23 receives the dough ball W2 at the receiving position G2. And the control apparatus 21 controls operation | movement of the 2nd transfer conveyor 23 based on the calculation result.

The second transfer conveyor 23 is a transfer device that receives a group of dough balls W2 conveyed by the processing conveyors (41 to 46) and transfers them onto a carry-out conveyor 15 described later. The entire second transfer conveyor 23 can be reciprocated back and forth along the Y direction, and can be moved up and down along the direction indicated by the arrow Z. Since the 2nd transfer conveyor 23 is the structure substantially the same as the 1st transfer conveyor 13, the same code | symbol is attached | subjected about the structure which has the same function, and detailed description is abbreviate | omitted. The second transfer conveyor 23 is attached to an elevating frame 22 provided on the downstream side of the multistage conveyor 14. And the raising / lowering frame 22 is equipped so that raising / lowering is possible according to the rotational drive of the servomotor M3.

The carry-out conveyor 15 is disposed below the front end (downstream side) of the sixth processing conveyor 46 configured in the multistage conveyor 14. The carry-out conveyor 15 is provided in parallel with the carry-in conveyor 12 so as to have the same conveyance direction. The height of the transport surface of the carry-out conveyor 15 is the same as that of the carry-in conveyor 12. The carry-out conveyor 15 is a belt conveyor that receives the group of dough balls W <b> 2 transferred from the second transfer conveyor 23 and conveys them to the subsequent hoisting device 7.

Next, the basic operation of the second transfer conveyor 23 will be described with reference to FIG. For convenience of explanation, a state where the second transfer conveyor 23 stands by at a position farthest from the carry-out conveyor 15 on the side of the carry-out conveyor 15 is defined as an initial position (see FIG. 6A). The second transfer conveyor 23 is raised in the direction of the arrow P11 (Z direction) at a position higher than the conveying surface position of any one of the conveyors 41 to 46 included in the multistage conveyor 14. Stop (see FIG. 6B). Here, the process until the second transfer conveyor 23 rises from the initial position and stops is referred to as an ascending process, and this time is referred to as an ascending process time TH.

Then, the actuator AC2 is driven to horizontally move the second transfer conveyor 23 in the direction of arrow P12 (opposite Y direction) (referred to as advance), and at the same time, the actuator AC1 is driven and the joint plate 21 is opposite to the arrow P12. In the direction (Y direction), the conveyor belt 20 is rotated clockwise. Then, the conveyor tip portion 23A of the second transfer conveyor 23 enters between the lower surface of the dough ball W2 and the corresponding conveying surface (upper surface) of the processing conveyor, and picks up the dough ball W2 on the upper surface of the conveyor belt 20 and receives it. (See FIG. 6 (c)).

At this time, the magnitude of the movement speed in the anti-Y direction of the second transfer conveyor 23 and the magnitude of the movement speed in the Y direction of the conveying surface 20A of the conveyor belt 20 in the second transfer conveyor 23 are the same. By this, the conveyance surface 20A of the conveyor belt 20 does not move with respect to the dough ball W2, and the tip portion of the conveyor belt 20 (tip portion 23A of the second transfer conveyor 23) can enter the lower surface of the dough ball W2. It becomes. In addition, the moving speed to the front and back of the 2nd transfer conveyor 23 and the rotational speed of the conveyor belt 20 can be adjusted separately. Further, the placement position of the center of the dough ball W2 with respect to the tip of the second transfer conveyor 23 can be set according to the size of the food to be placed and the interval of each food on the multistage conveyor 14. The second transfer device 23 that has picked up the dough ball W2 moves in the direction of the arrow P13 (Y direction) and moves back to the same horizontal position as the initial position (see FIG. 6D). Here, the process until the second transfer conveyor 23 moves forward and the backward movement ends is referred to as a transfer process, and this time is referred to as a transfer process time TI.

The second transfer conveyor 23 descends in the direction of the arrow P14 (counter Z direction) and returns to the initial position (see FIG. 6E). Here, this is referred to as a descent process, and this time is referred to as a descent process time TJ. And it stops for the required time at the descending position (initial position). Here, the descending position stop process is referred to as a descending position stop process time TK. Thereafter, the second transfer device 23 moves forward in the horizontal direction (counter-Y direction) indicated by the arrow P15, and the conveyor tip portion 23A of the second transfer conveyor 23 is located above the transport surface of the carry-out conveyor 15. Stop (see FIG. 6F).

The second transfer device 23 moves the joint plate 21 in the direction of the arrow Y with respect to the conveyor plate 17 while horizontally moving (referred to as retreating) in the direction (Y direction) indicated by the arrow P16. The 20 conveying surfaces 20A are moved in the direction opposite to the arrow P16 (counter Y direction), and the conveyor belt 20 is rotated counterclockwise. At this time, if the magnitude of the moving speed in the Y direction of the second transfer conveyor 23 and the magnitude of the moving speed in the anti-Y direction of the conveying surface 20A of the conveyor belt 20 in the second transfer conveyor 23 are the same. The second transfer conveyor 23 is pulled out from below the dough ball W2 without moving the dough ball W2 in the horizontal direction, and the dough ball W2 falls from the front end portion 23A of the second transfer conveyor 23 and is carried out by the carry-out conveyor 15. On the transport surface. The second transfer conveyor 23 moves horizontally in the direction of the arrow Y and returns to the initial position (see FIG. 6A). Here, the process until the second transfer conveyor 23 moves forward and the retreat is completed is referred to as a transfer process, and this time is referred to as a transfer process time TL.

The second transfer conveyor 23 waits until it receives the next group of dough balls W2 at the initial position. Here, it is referred to as a standby process, and this time is referred to as a standby process time TM. This series of steps is defined as one cycle. By sequentially repeating this series of steps for the first processing conveyor 41 to the sixth processing conveyor 46 of the multi-stage conveyor 14, the group of dough balls W2 can be stably supplied to the carry-out conveyor 15.

In the operation of the second transfer conveyor 23 according to the present embodiment, the operation is controlled so that the transfer process time TI and the transfer process time TL are the same in each process described above. However, the descent process time TJ of the second transfer conveyor 23 varies due to the distance (height) from the position corresponding to each processing conveyor 41 to 46 of the multistage conveyor 14 to the initial position. That is, the descending process time TJ from the first processing conveyor 41 is the longest, and the descending process time TJ from the sixth processing conveyor 46 is the shortest. Therefore, the descent position stop process time TK is controlled to a time corresponding to the descent process time TJ so that the time required for the transfer process, the descent process, the descent position stop process, and the transfer process is constant.

That is, even if the second transfer conveyor 23 transfers the dough ball W2 from any processing conveyor and supplies it to the carry-out conveyor 15, the total time required for the descent process and the descent position stop process is controlled to be constant. To do. By controlling in this way, the group of dough balls W2 transferred to the carry-out conveyor 15 does not overlap with another group of dough balls W2 to be transferred next, and the stable transfer of the dough balls W2 can be performed. It becomes possible. The descending process time TJ can be set based on an empirical rule, and the corresponding descending position stop time TK is calculated by the arithmetic processing unit 33 by setting in advance in the control device 31.

As can be understood from the above description, when a group of foods consisting of a plurality of foods is transferred between the conveyors in the food conveyance processing apparatus, the row of the foods is not disturbed, so that the foods can be stably conveyed. In addition, when food is transferred, the adhesion of the food to the conveyor can be suppressed, and it can be transported without impacting the food due to inversion and falling, so that the shape of the supplied food is not disturbed and follows. The food shape is stably molded in the treatment process.

An alignment conveyor 16 is connected to the downstream side of the food conveyance processing device 5, specifically, the downstream side of 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, the gathering part S of the dough balls W2 supplied to the hoisting device 7 is preferably located on the upper surface side of the dough balls W2. For example, the transport surface of the alignment conveyor 16 is higher than the transport surface of the carry-in conveyor 81. By arranging and providing a step between the two conveyors, the upper and lower surfaces of the dough ball W2 can be reversed when transferring from the alignment conveyor 16 to the carry-in conveyor 81.

In addition, for example, when manufacturing products such as buns, an array device that arranges the dough balls W2 in a multi-row, multi-row arrangement on a display plate without performing secondary molding such as flattening and rolling up the dough ball W2, or an oven, etc. It is also possible to provide a heat treatment device on the downstream side of the food conveyance processing device 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 food conveyance processing device 5.

The description of the food conveyance processing apparatus according to the embodiment of the present invention is generally as described above. However, the present invention is not limited to this, and various modifications can be made within the scope of the claims. For example, although the dough supplied to the food conveyance processing apparatus 5 has been described as the dough ball W2, the dough ball W2 can also be used in a hoisting fabric W4 obtained by winding a flaky dough sheet W3. It is possible to carry it. In this case, when the hoisting cloth W4 is transferred to each transfer conveyor, it is desirable that the roll dough W4 is pressed slightly flat to prevent it from rolling without being placed on the transfer conveyor. In addition, various kinds of doughs can be conveyed and applied as a food processing and conveying device as a rest conveyor, proofer, steamer, or the like.
