The measuring unit 8 is arranged in the frame F. The measuring unit 8 has a plurality of load cells 8a. Each load cell 8a supports a corresponding weighing hopper 5. Each load cell 8a outputs a weighing value corresponding to the mass of the article when the article is temporarily stored in each weighing hopper 5. The charge hopper 2, the feeder 3, the plurality of pool hoppers 4, the plurality of measuring hoppers 5, the pair of conveyors 6, and the chute 7 are directly or indirectly supported by the frame F.

A more detailed configuration of the charge hopper 2 will be described with reference to FIGS. 4 to 7. In FIGS. 4 to 7, the feeder 3, the pool hopper 4, the weighing hopper 5, the conveyor 6 and the chute 7 are omitted. The charge hopper 2 has a first state (states of FIGS. 4 and 5) for supplying an article to the measuring hopper 5 and an article to the charging section 21 because the charging section 21 is movable with respect to the discharging section 22. It is configured to be switchable between the second state (the state shown in FIG. 6) for inputting. The combination weighing device 1 further includes an actuator (first actuator, second actuator) 9 for driving the charging unit 21.

The actuator 9 is, for example, a telescopic air cylinder. One end of the actuator 9 is fixed to the frame F, and the other end of the actuator 9 is fixed to the back surface of the mounting surface 21a in the loading portion 21. The input section 21 is connected to the frame F via the link section 13 and the link section 14. A pair of link portions 13 and 14 may be provided so as to be arranged in the width direction (the paper depth direction in FIG. 5). The link portions 13 and 14 are rotatably connected to the closing portion 21 and the frame F about the connection point. As a result, the charging unit 21 moves according to the expansion and contraction of the actuator 9, and the state of the charge hopper 2 is switched between the first state and the second state.

Both the position and the posture of the throwing unit 21 are different between the first state and the second state. In the first state, the loading unit 21 is located at the supply position for supplying the article to the discharging unit 22. The charging section 21 is located in the vicinity of the discharging port 22b of the discharging section 22, and the front edge portion of the charging section 21 extends along the discharging port 22b. Further, the mounting surface 21a of the charging portion 21 is inclined with respect to the horizontal plane so as to face the front side. As a result, the article staying on the mounting surface 21a moves to the discharge port 22b side due to gravity and is discharged to the discharge unit 22.

In the second state, the charging unit 21 is located at the loading position where the article is loaded into the charging unit 21. The position of the charging unit 21 in the second state is located vertically below the position of the charging unit 21 in the first state. The position of the charging unit 21 in the second state is located on the rear side (opposite side to the measuring hopper 5) with respect to the position of the charging unit 21 in the first state when viewed from the vertical direction. The position of the charging unit 21 in the first state is closer to the discharge port 22b than the position of the charging unit 21 in the second state.

Further, in the second state, the mounting surface 21a of the charging portion 21 is inclined with respect to the horizontal plane so as to face the rear side. This facilitates the loading of the article into the loading unit 21. In the second state, the rear surface 21b of the charging unit 21 prevents the article charged into the charging unit 21 from falling. The inclination angle β of the mounting surface 21a with respect to the horizontal plane in the second state is larger than the inclination angle α of the mounting surface 21a with respect to the horizontal plane in the first state. When comparing the positions of the charging unit 21 in the first state and the second state, the positions of the same positions in the charging unit 21 are compared.

Further, as shown in FIG. 7, in the first state, the actuator 9 is further extended to move the rear portion of the mounting surface 21a upward with respect to the front portion, and the mounting surface 21a is tilted with respect to the horizontal plane. The angle α can be further increased. By increasing the inclination angle α, the article on the mounting surface 21a is easily discharged to the discharge unit 22.

As shown in FIG. 3, the combination weighing device 1 further includes a first detection unit 11, a second detection unit 12, and a control unit 15. The first detection unit 11 detects the retention state of the article staying in the discharge unit 22. The first detection unit 11 is, for example, a camera that photographs a region where articles stay on the mounting surface 22a from above. The first detection unit 11 is fixed to the frame F, for example.

The second detection unit 12 detects the retention state of the article staying in the charging unit 21. The second detection unit 12 is, for example, a camera that photographs a region where articles stay on the mounting surface 21a from above. The second detection unit 12 is fixed to, for example, the charging unit 21.

The control unit 15 is arranged in the frame F. The control unit 15 is an arithmetic unit having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control unit 15 performs combined weighing such as a transfer operation of the feeder 3, an opening / closing operation of the gate 4a of each pool hopper 4, an opening / closing operation of the gate 5a of each measuring hopper 5, a transfer operation of each conveyor 6, and an expansion / contraction operation of the actuator 9. It controls the operation of each part of the device 1. The control unit 15 is communicably connected to the measuring unit 8, the first detection unit 11, the second detection unit 12, the bag making and packaging machine, and the like.

The control unit 15 has a measurement control unit 16 that executes a combination measurement process. The measurement control unit 16 stores the measurement value measured by the measurement unit 8 and the measurement hopper 5 for storing the article corresponding to the measurement value in association with each other. The measurement control unit 16 selects a combination of measurement values from a plurality of measurement values measured by the measurement unit 8 and associated with each measurement hopper 5 so that the total value becomes the target measurement value. More specifically, the measurement control unit 16 selects a combination of measurement values from a plurality of measurement values output by the measurement unit 8 so that the total value falls within a predetermined range with the target measurement value as the lower limit value. .. Then, the measurement control unit 16 causes the measurement hopper 5 corresponding to the combination to discharge the article.

The control unit 15 further includes an actuator control unit (first actuator control unit, second actuator control unit) 17 that controls the actuator 9. In the case where the charge hopper 2 is in the first state, the actuator control unit 17 changes the charge hopper 2 from the first state to the second state when the amount of articles staying in the charging unit 21 becomes less than the first set amount. The actuator 9 is controlled so as to be. The actuator control unit 17 grasps the amount of articles staying in the loading unit 21 based on the detection result of the second detection unit 12. By this control, when the article is gradually discharged from the loading section 21 to the discharging section 22 in the first state and the amount of the article staying in the loading section 21 becomes smaller than the preset first set amount, the article is loaded. The unit 21 moves from the supply position to the charging position, and the charge hopper 2 switches from the first state to the second state. In this second state, the article is charged into the charging unit 21. The loading of the article into the loading unit 21 may be performed manually, for example, or may be performed by an automated machine.

Further, in the actuator control unit 17, when the charge hopper 2 is in the second state and the amount of articles staying in the charging unit 21 becomes larger than the second set amount, the charge hopper 2 is moved from the second state to the first state. The actuator 9 is controlled so as to be in the state. The second set amount is a larger amount than the first set amount. By this control, when a sufficient amount of articles are charged into the charging section 21 in the second state and the amount of articles staying in the loading section 21 becomes larger than the preset second set amount, the loading section 21 Moves from the charging position to the supply position, and the charge hopper 2 switches from the second state to the first state.

Further, the actuator control unit 17 sets the actuator 9 so that when the charge hopper 2 is in the first state, the inclination angle α of the mounting surface 21a with respect to the horizontal plane increases as the number of articles staying in the discharge unit 22 decreases. Control. The actuator control unit 17 grasps the amount of articles staying in the discharge unit 22 based on the detection result of the first detection unit 11. By this control, the amount of articles supplied from the input unit 21 to the discharge port 22b in the first state is stabilized.

As described above, in the combination weighing device 1, the charge hopper 2 loads the article into the charging hopper 21 and the first state for supplying the article to the weighing hopper 5 because the charging section 21 is movable. It is configured to be switchable between the second state and the second state. As a result, when the article is loaded, the article can be loaded into the loading section 21 in the second state for loading the article into the loading section 21. Further, after the article is put in, it is possible to switch to the first state for supplying the article to the measuring hopper 5 and supply the article to the measuring hopper 5. Therefore, according to the combination weighing device 1, the workability when the article is put into the charge hopper 2 can be improved.

Further, in the combination weighing device 1, the position of the charging unit 21 in the second state is located vertically below the position of the charging unit 21 in the first state.

Can be changed.

Further, in the combination weighing device 1, the position of the charging unit 21 in the first state is closer to the discharge port 22b than the position of the charging unit 21 in the second state. As a result, in the first state, the article can be supplied to the discharge section from the input section 21 located near the discharge port 22b. Further, in the combination weighing device 1, the input unit 21 is movable with respect to the discharge unit 22. As a result, since only the charging unit 21 is movable, the configuration can be simplified.

Further, in the combination weighing device 1, when the charge hopper 2 is in the first state, the actuator control unit 17 increases the inclination angle α of the mounting surface 21a with respect to the horizontal plane as the number of articles staying in the discharge unit 22 decreases. The actuator 9 is controlled so as to do so. As a result, it is possible to suppress the occurrence of damage to the article and the bridging phenomenon (clogging of the article) due to the rapid supply of the article to the discharge unit 22.

Further, in the combination weighing device 1, the actuator control unit 17 causes the charge hopper 2 to move when the amount of articles staying in the charging unit 21 becomes less than the first set amount in the case where the charge hopper 2 is in the first state. The actuator 9 is controlled so as to change from the first state to the second state. As a result, workability when loading an article into the charge hopper 2 can be further improved.
