Description

  The present invention relates to a combination weigher that selects a combination of a plurality of weighing units to which an object to be weighed is supplied and puts an object to be weighed in a predetermined weight range into a packaging machine or the like.

  As the combination weigher, for example, there is a semi-automatic combination weigher in which an object to be weighed is manually input by an operator. This semi-automatic combination weigher is usually provided with a plurality of weighing hoppers arranged in a straight line and a transfer conveyor arranged below each weighing hopper, and an operator can place an object to be weighed on the weighing hopper. Directly or indirectly through a supply hopper above the weighing hopper. Based on the weight value of the objects to be weighed in each weighing hopper, combination calculation is performed and the combined weight, which is the combined total weight, is equal to or close to the target combination weight. The combination is selected, and the objects to be weighed by the weighing hopper selected for the appropriate combination are discharged to the conveyor. The transport conveyor transports an object to be weighed in a transport direction, which is a direction in which a plurality of weighing hoppers are arranged, and puts it into a subsequent apparatus, for example, a packaging machine, from the end of the transport.

  In such a combination weigher, the object to be weighed that is input to the packaging machine from the conveyance end of the conveyor is temporarily held, and the object to be weighed can be input to the packaging machine in accordance with the discharge command from the packaging machine. There is one in which a collecting gate is provided below the terminal (for example, Patent Document 1). By providing the collecting gate, the objects to be weighed sequentially from the conveyance end of the conveyor can be put together into the packaging machine, so that the objects to be weighed sequentially from the conveyance end can be put into the packaging machine as they are. In comparison, the time required for loading into the packaging machine can be shortened. Thereby, the cycle time of the packaging process in the packaging machine can be shortened, and the operation speed of the entire weighing and packaging system including the combination weigher can be increased.

JP 2012-242102 A

  In the production line in which the objects to be weighed are weighed with the combination weigher as described above, the objects to be weighed in the predetermined weight range are put into the packaging machine, and the objects to be weighed are packaged with the packaging machine, for example, the packaging machine is a new type. In the case of changing the layout, such as changing to a thing, it is required to correctly align the discharge port of the collecting gate that discharges the objects weighed by the combination weigher and the input port of the packaging machine.

  Actually, the combination weigher and the packaging machine are temporarily positioned and temporarily operated, and the objects to be weighed from the combination weigher are properly supplied to the input port of the packaging machine through the collecting gate, and the desired packaging processing is performed. If there is a problem, repeat the alignment and temporary operation to move one or both of the combination weigher and the packaging machine finely on the floor. Will be aligned.

  However, in general, a large and heavy combination weigher installed on the floor and / or one or both of the packaging machines need to move a lot on the floor and require a lot of work and time to adjust the height. As a result, a prompt layout change is hindered.

  Furthermore, the collecting gate is disposed at a position lower than the conveyance end of the conveyance conveyor, temporarily holds the objects to be weighed sequentially by the conveyance conveyor, and then opens the gate to collect the objects to be weighed. Therefore, the input speed is lower than the case where the objects to be weighed that are sequentially transported by the transport conveyor are directly input to the input port of the packaging machine without providing a collecting gate. Since the objects to be weighed are also collected, when the objects to be weighed discharged from the collecting gate come into contact with the inner wall of the packaging machine's inlet and the falling speed decreases, the following objects to be weighed up and the objects to be weighed are clogged. May occur.

  Therefore, not only the above-mentioned layout change, but also when switching the type or lot of the objects to be weighed, the objects to be weighed will depend on the size and shape of the objects to be weighed, In some cases, it may be desirable to finely adjust the positions of the discharge port of the collecting gate of the combination weigher and the input port of the packaging machine so that it does not come into contact with the inner wall.
