The slope 162b is a slope that becomes an uphill toward the operating position P1. The notch 162c is a notch that is recessed in a valley shape at the top of the slope 162b that becomes an uphill toward the operating position P1. The lock mechanism 177 engages with the engaging member 162 by positioning the lock bar 177b in a pair of notches 162c when the support unit 17 is located at the operating position P1.

The lock mechanism 177 is released from the engaging member 162 by being operated toward the handle 178 when the support unit 17 is located at the operating position P1. More specifically, when the operator pulls the operation bar 177c toward the grip portion 178a with one hand and positions the lock bar 177b outside the pair of notches 162c, the lock mechanism 177 is released from the engaging member 162. Will be done. As a result, the operator can move the support unit 17A from the operating position P1 to the maintenance position P2 by holding the handle 178 during maintenance of the combination weighing device 1.

The lock mechanism 177 engages with the engaging member 162 by being driven when the support unit 17A moves from the maintenance position P2 to the operating position P1. More specifically, when the operator holds the handle 178 and moves the support unit 17A from the maintenance position P2 to the operation position P1, the lock bar 177b goes up a pair of slopes 162b and a pair. The locking mechanism 177 engages with the engaging member 162 by falling into the notch 162c of.
[Action and effect]

In the combination weighing device 1, the support units 17A that support the pair of distribution timing hoppers 7A and 7B are located below the lower ends of the respective collective chute 6A and 6B along the pair of guide rails 161 of the guide unit 16A. It is possible to move from the operation position P1 of the above to the maintenance position P2 outside the base 13. Further, the support unit 17B supporting the pair of distribution timing hoppers 7C and 7D is located along the pair of guide rails 161 of the guide unit 16B, and the operation position P3 below the lower end of each of the collective chute 6C and 6D. Therefore, it is possible to move to the maintenance position P4 outside the base 13. As a result, the operator can attach / detach the distribution timing hoppers 7A, 7B, 7C, and 7D at the maintenance positions P2 and P4 outside the base 13 without accessing the lower side of the base 13. Therefore, according to the combination weighing device 1, the distribution timing hoppers 7A, 7B, 7C, and 7D can be easily attached and detached.

Further, in the combination weighing device 1, a pair of guide rails 161 are installed on the gantry 14, and the support units 17A and 17B move on the pair of guide rails 161. This enables stable installation of the pair of guide rails 161 and stable movement of the support units 17A and 17B. In addition, the operator can perform work related to attachment / detachment of each distribution timing hopper 7A, 7B, 7C, 7D on the gantry 14.

Further, in the combination weighing device 1, the lock mechanism 177 is driven when the support unit 17A moves from the maintenance position P2 to the operation position P1, so that the lock mechanism 177 engages with the engaging member 162 of the guide unit 16A. When the support unit 17A is located at the operating position P1, the lock mechanism 177 is operated toward the handle 178 side, so that the lock mechanism 177 is released from the engaging member 162. Further, when the support unit 17B moves from the maintenance position P4 to the operation position P3, the lock mechanism 177 is driven so that the lock mechanism 177 engages with the engaging member 162 of the guide unit 16B, and the support unit 17B is in the operation position. When the lock mechanism 177 is operated toward the handle 178 when it is located at P3, the lock mechanism 177 is released from the engaging member 162. As a result, the operator holds the handle 178 and moves the support units 17A and 17B from the maintenance positions P2 and P4 to the operation positions P1 and P3, whereby the support units 17A and 17B are operated. It can be easily fixed to the positions P1 and P3. Further, the operator holds the handle 178 and operates the lock mechanism 177 toward the handle 178 in order to move the support units 17A and 17B from the respective operating positions P1 and P3 to the respective maintenance positions P2 and P4. The lock mechanism 177 can be easily released from the engaging member 162.

Further, in the combination weighing device 1, the first link mechanism 175 for the distribution timing hopper 7A is the first drive motor 173 for the distribution timing hopper 7A in the Y-axis direction and the first gate 73 of the distribution timing hopper 7A. On the outside, the first drive motor 173 and the first gate 73 are connected to each other. Further, the second link mechanism 176 for the distribution timing hopper 7A is located outside the second drive motor 174 for the distribution timing hopper 7A and the second gate 74 of the distribution timing hopper 7A in the Y-axis direction. The drive motor 174 and the second gate 74 are connected to each other. The first link mechanism 175 and the second link mechanism 176 for the other distribution timing hoppers 7B, 7C, and 7D are similarly configured. As a result, the operator can access the first link mechanism 175 and the second link mechanism 176 for each distribution timing hopper 7A, 7B, 7C, 7D from the same side, so that each distribution timing hopper 7A, 7B, 7C , 7D can be easily attached and detached.

Further, according to the gantry 14 for the combination weighing device 1 including the pair of guide units 16A and 16B and the pair of support units 17A and 17B, the distribution timing hoppers 7A and 7B, respectively, for the reasons described above. 7C and 7D can be easily attached and detached.
[Modification example]

The present invention is not limited to the embodiments described above. For example, in the above-described embodiment, one combination weighing device 1 is configured with four supply systems, but one combination weighing device 1 may be configured with one supply system, or one combination weighing device 1 may be configured with one supply system. The device 1 may be configured with five or more supply systems. As described above, the matter concerning the quantity in the above-described embodiment is not limited to the above-mentioned example. Various known configurations can be adopted for each configuration of the combination weighing device 1 (for example, a configuration from the dispersion feeder 2 to the collective chute 6).

Further, the pair of guide rails 161 is not limited to those installed on the gantry 14, and may be embedded in the gantry 14, for example. Further, the guide units 16A and 16B are not limited to those having a pair of guide rails 161 as long as they have guide members that allow the support units 17A and 17B to move.
