JP 2004-314983 A

In food conveying devices that control the number of rotations of pipes with multiple hypes in parallel, the drying tool materials cut out from the pipe connection ports and pipes in parallel at the lower part of the hopper change the type of the weighing drying material and change the contents. Depending on the shape and size, the pipes are operated in different directions and directions. However, in the control that transports the drying tool material by controlling all the parallel pipes at the same number of rotations, the pipes located on both sides of the parallel pipes reduce the inflowing drying material due to the influence of the wall surface of the hopper. For this reason, there is a tendency that the cutting ability of the drying tool material of the pipes located at both ends is reduced and it takes time, and as a result, it is difficult to exert the production capacity of the food conveying device.

The present invention has been made in view of such circumstances, and an object of the present invention is to improve productivity by increasing the cutting speed of pipes located on both sides of a plurality of pipes arranged in parallel to the lower part of a hopper in a food conveying device.

The food conveying device according to claim 1, which meets the object, includes a hopper capable of storing the drying tool material and discharging it from the lower part to the pipe feeder, and three or more connection ports provided in parallel to the lower part of the hopper, At least three or more pipe feeders that are rotationally driven by the respective motors, connected to the connection ports, and inclined downward, and the drying tool material cut out through the pipe feeders are temporarily stored. A food transport device comprising a plurality of buckets and a control unit that controls the rotation of the motor so as to cut the drying tool material so that the weights of the drying tool materials in the buckets are equal to each other.

By determining the speed, the amount of cut out of all parallel pipe feeders is made uniform.

In the food conveying device according to claim 1, since the drying tool material flowing into the pipe feeder located at both ends is reduced due to the influence of the rotating pipe feeder and the side wall of the hopper, the pipe feeder located at both ends thereof It takes more time to cut out a certain amount of the drying material than other pipe feeders, and as a result, the cutting ability of the food conveying device is lowered. Therefore, the rotation speed of the pipe feeders located at both ends is controlled to be larger than the rotation speeds of the pipe feeders at other positions, so that the cutting performance per time of all the pipe feeders becomes constant, so that the food transport It becomes possible to improve the productivity by increasing the operation rate of the apparatus.

In particular, in the food conveying device according to claim 2, the level sensor for detecting the drying material stored in the side surface portion of the hopper, the level sensor for the side surface portion of the hopper to which a pipe feeder located at the end is adjacent. On the other hand, by rotating the pipe feeder in the direction of escaping in the opposite direction, it is possible to reduce the influence of the drying tool material wound up by the rotation of the pipe feeder, and to accurately grasp the amount of stored drying tool material It is possible to increase the operating rate of the food conveyance device.

In particular, in the food conveying apparatus according to claim 3, the rotational speed of the pipe feeders located at both ends determines the rotational speed according to the distance of the pipe feeders close to the hopper wall surface, and all the parallel pipe feeders By making the amount of cut out uniform, it becomes possible to improve the production capacity of the food conveying device.

As shown in FIG. 1, a food conveying device 10 according to an embodiment of the present invention includes a hopper 12 that stores a drying tool material 11, a level sensor 27 that is detected by the drying tool material 11 in the hopper 12, and a drying device. A supply motor 26 for supplying the member 11 into the hopper 12 is provided. A downwardly inclined pipe feeder 13 that is connected to the hopper 12 to cut out the drying tool material 11 and a motor 21 that rotates the pipe feeder 13 are provided. Next, the bucket 14 that receives the drying tool material 11 dropped from the pipe feeder 13 and the drying tool material 11 in the bucket 14 are used as an example of a solenoid 22 (here, an example of driving means. The drive means is an actuator driven by hydraulic pressure, pneumatic pressure, water pressure, and electric drive). And the load cell 23 which measures the drying tool material 11 which the bucket 14 received is also provided.

Here, as an example, the open / close sensor 24 detects the presence / absence of the drying material 11 stored in the discharge chute 15, and the open / close sensor 24 detects whether the discharge lid 15a has been opened or closed. If it is once opened, it is indirectly determined that the drying tool material 11 is not contained.

The control unit 20 controls rotation by turning on and off the applied voltages of the motor 21 and the supply motor 26 which are DC motors. Note that the rotation speed of the motor 21 is switched by switching the applied voltage. Further, the solenoid 22 and the discharge solenoid 25 are also driven and controlled by turning on and off the applied voltage. Furthermore, the measurement value from the load cell 23 is taken in, and the detection results of the open / close sensor 24 and the level sensor 27 are taken in and controlled. The level sensor 27 uses a reflective photoelectric sensor here. And the presence or absence of the drying tool material 11 stored in the inside of the hopper 12 is detected in the detection area in front of the level sensor 27, and the storage amount of the drying tool material 11 is measured.
Usually, for example, a plurality of pipe feeders 13, 13 a, 13 b, and 13 c are provided, and motors 21, 21 a, 21 b, 21 c, etc. are provided for the respective driving and controlled by the control unit 20. .

Then, the type and target weight of the drying tool material are input and controlled by the operation panel 28. Specifically, since the specific gravity differs for each product name, the target weight to be cut out is set as a standard. For example, if it is a dry leek, it is 3g. This target weight can be changed by operation. And the control part 20 is communicating with the packaging control part 29 in a post process, and the control part 20 controls supply of the drying tool material 11 according to the driving | running state of a packaging apparatus (not shown). And the control means 30 is comprised with a program and controls the food conveyance apparatus 10. FIG.

In FIG. 2, the perspective view of the food conveyance apparatus which concerns on one embodiment of this invention is shown. The whole is a triangular prism shape, which is rectangular in plan view, and has a triangular shape with a horizontal cross-section decreasing downward. Four pipe feeders 13, 13 a, 13 b, 13 c are arranged in parallel and attached to the bracket 40. Connection ports 18, 18a, 18b, and 18c (see FIG. 3) are provided in the lower part of the hopper 12, and four pipe feeders 13, 13a, 13b, and 13c are fitted therein, and each is mounted on the plate 41. Is placed. In addition, a level sensor 27 is provided at an intermediate portion on both sides of the hopper 12 so as to detect the amount of the stored drying tool 11 stored in the hopper 12.

In FIG. 3, the explanatory drawing of the cross section of the food conveyance apparatus which concerns on one embodiment of this invention is shown. Here, it demonstrates centering on the pipe feeder 13. FIG. First, the hopper 12 has a triangular shape in which a horizontal section is reduced downward. And the connection port 18 is provided in the lower end part, and the several pipe feeders 13, 13a, 13b, 13c (13a, 13b, 13c is not shown in figure) are each connected. Further, pipe feeders 13, 13 a, 13 b, and 13 c are provided on a plate 41 provided substantially horizontally at the lower end of the hopper 12. At the upstream end of the pipe feeders 13, 13 a, 13 b, 13 c, the drying tool material 11 accumulated in the connection ports 18, 18 a, 18 b, 18 c (18 a, 18 b, 18 c is not shown) of the hopper 12 is cut out downstream. To supply. And also on the plate 41, each pipe feeder 13, 13a, 13b, 13c is mounted. Each of them is also placed on the plate 41. A hinge portion 42 is provided on the lower surface of the front end portion of the plate 41, and an inclination adjusting portion 43 for adjusting the inclination by rotation of a screw is provided on the lower surface of the rear end portion of the plate 41. And by adjusting the inclination of the plate 41, the inclination of the pipe feeders 13, 13a, 13b, 13c is also interlocked so that the cutting speed (the amount of cutting) of the drying tool 11 by the pipe feeder 13 can also be adjusted. Note that as the inclination increases, the cutting speed also increases.

FIG. 4 shows the storage state of the hopper and the drying tool of the food conveying device according to the embodiment of the present invention. Here, a cross section in the front-rear direction of the hopper 12 shows from the outlet direction, and the drying tool 11 is stored. In addition, level sensors 27 are provided at the intermediate portions on both side surfaces of the hopper 12 so as to face the inside of the container of the hopper 12 to detect the presence or absence of the stored drying member 11. In addition, the state of the vicinity of the connection port which each pipe feeder 13, 13a, 13b, 13c is driving at the same rotational speed is shown. During operation of the food conveying device 10, the desiccant material 11 is stored in a state in which the desiccant material 11 is mountain-shaped toward both ends of the wall surface so as to be pulled in the vicinity of the side wall surface of the hopper 12. It will be cut out. Note that, depending on the distance (L) from the wall surface to the pipe feeder 13, if L is large, the mountain becomes gentle, and if L is small, the mountain becomes steep. However, since there is a restriction on the width of the food conveyance device 10, L cannot be increased unnecessarily. Usually, it is 50 mm or less. The pipe feeders 13 and 13b are driven to rotate counterclockwise (counterclockwise), and the pipe feeders 13a and 13c are driven to rotate clockwise (clockwise). The rotation direction is determined so that the rotation of the pipe feeder 13 is directed toward the center of the hopper 12 so that the drying tool 11 does not move toward the detection surface direction of the level sensor 27. Similarly, the rotation direction is determined so that the rotation of the pipe feeder 13c is directed toward the center of the hopper 12 so that the drying tool 11 does not move toward the detection surface direction of the level sensor 27a. Moreover, the upper surface of the drying tool material 11 stored above the pipe feeders 13, 13 a, 13 b, and 13 c cancels the influence of the drying tool material 11 that is cut out by making the rotation directions of adjacent pipe feeders different. As a result, the adjacent pipe feeders 13a and 13b are stabilized in their cutout amounts, but the pipe feeders 13 and 13c at both ends further increase the operation rotational speed of the motor 21 to be driven. Then, the mountain-shaped drying tool 11 on both sides is reduced, and the setting is made so as not to prevent the detection of the level sensor 27. That is, the rotation direction of the pipe feeders at both ends is the right rotation direction while the adjacent hopper wall surface is located on the left side with respect to the cutting direction of the drying tool material, and the adjacent hopper wall surface is on the right side. The other located is the left rotation direction. By doing so, the upper surface of the drying tool material 11 stored by raising the cutting ability of the pipe feeders 13 and 13c at both ends can be further averaged. As a result, the availability of the food feeder 10 can be increased by making the cutting ability of the pipe feeders 13, 13a, 13b, and 13c uniform.

FIG. 5 shows a flowchart for setting the motor speed of the food conveyance device according to the embodiment of the present invention. Here, the control means 20 sets the operation rotational speed of the motor 21 that drives each of the pipe feeders 13, 13a, 13b, and 13c. First, in S001, the motors 21, 21a, 21b, and 21c are set to the standard rotational speed P1 (for example, 100 rms), respectively. Next, in S002, the motor 21 at the right end is reset again to a rotational speed P2 (for example, 120 rms) that is larger than P1. Further, in S003, the leftmost motor 21c is reset to a rotational speed P2 (for example, 120 rms) larger than P1. Then, the setting of the motor rotation speed is completed, and the drying tool material accumulated in the hopper 12 is cut out at the set motor rotation speed. Here, if P1 is 100 rms, P2 is preferably about 120 rms. By setting the motors at both ends to such a rotational speed, the cutting ability of the pipe feeder can be improved conventionally.
Furthermore, as described above, by setting the motor rotation direction so that adjacent motors rotate in opposite directions, the cut-out amount of adjacent pipe feeders becomes the same amount, and the cut-out time is averaged. To do.

The present invention has been described above with reference to the embodiment. However, the present invention is not limited to the configuration described in the above embodiment. For example, three or more pipe feeders are used in the hopper. When the motor is driven by automatically learning and increasing the motor rotation speed so that the cut-out time is constant, other embodiments considered within the scope of the matters described in the claims, Modifications are also included.
