Description

[Detailed description of the invention] The present invention relates to a receiver conveyance device for weighed items in a new weighing machine, etc., in which loading of empty containers may be carried out irregularly in time. A constantly rotating belt conveyor 2 for feeding containers is delivered under the supply port 1 for weighed items, etc., and a constantly rotating belt conveyor 3 for returning empty containers is placed below this feeding belt conveyor 2 so that the conveying direction is The base end of the belt conveyor 2 for receiving receivers and the tip of the belt conveyor 3 for returning are provided in opposite directions to each other, and the belt conveyor 3 for returning and the belt conveyor 3 for returning and the feeding belt are provided on the outside of the aligned ends. A remote-controlled elevator 4 that moves up and down intermittently between the conveyor belt 2 and the empty container 2 each time an empty container is delivered or received.
When the platform 5 descends, the empty container A is automatically placed on the platform 5 of the elevator 4 due to the inertia of the conveying force of the return belt conveyor 3, and when the platform 5 also ascends, it tilts downward and lifts the container. A remote controller movable tray 6 is installed to slide the container A onto the feeding belt conveyor 2, and a remote control movable tray 6 is placed next to the returning belt conveyor 3 after the first empty container transported by the returning belt conveyor 3 is moved. By protruding the bar bar 7 into the moving space of the empty container to stop the movement of the second empty container in a slip state, and also removing the bar bar 7 from the moving space to eliminate the stoppage, the second empty container is moved. A remote control type empty container standby stopper 8 that allows the movement of the first empty container is installed next to the feeding belt conveyor 2 in front of the empty container being conveyed by the same feeding belt conveyor 2. By protruding the bar 9, the movement of the empty container is stopped in a slip state as a receiver 1' under the above-mentioned supply port 1, and after receiving the weighed object, the bar 9 is removed from the moving space and the container is placed in the container. Each of the apparatuses is equipped with a remote control type receiver standby stopper 10 which allows the receiver A' to be moved by releasing the stoppage.

Since the present invention has the above-mentioned configuration, the empty container A mounted on the base end of the return belt conveyor 3 is blocked by the empty container standby stopper 8 and is in a slip state on the top end of the return belt conveyor 3. After waiting there, the empty containers are guided one by one onto the feeding belt conveyor 2 by the elevator 4, and the one empty container is placed on the receiving stopper 10.
It waits under the supply port 1 in a slip condition because it is obstructed by The weighed items therein are opened and placed on the base end of the return belt conveyor 3 as an empty container.

As described above, the present invention is to deliver a constantly rotating belt conveyor for feeding a receiver under the supply port for weighed objects, etc. Equipped with a belt conveyor for
Below this feeding belt conveyor, there is a constantly rotating empty container return belt conveyor in a state where the conveying directions are opposite to each other and the base end of the feeding belt conveyor and the tip of the returning belt conveyor are aligned. At the same time, a remote-controlled elevator is placed outside the aligned end of the belt and moves up and down intermittently between the return belt conveyor and the forwarding belt conveyor each time an empty container is delivered or received. The platform is equipped with a movable tray that automatically places an empty container on it by the inertia of the conveying force of the return belt conveyor when the elevator platform descends, and also tilts downward when the platform ascends to allow the empty container to slide down onto the feed belt conveyor. Therefore, by setting the tip of the belt conveyor for receptacle feeding and the base end of the belt conveyor for container return close to each other, it is possible to feed weighed items of containers from the same position to the lower part of the supply port, and also to feed the same container from the same position. The return to the above-mentioned position from the lower part of the mouth can be performed automatically, and furthermore, in this invention, the first empty container conveyed by the return belt conveyor is placed next to the return belt conveyor. After the movement, a bar bar is projected into the moving space of the empty container to stop the movement of the second empty container in a slip state, and the bar bar is also removed from the moving space to eliminate the stoppage, thereby causing the second empty container to move. A remote-controlled empty container standby stopper is installed to allow the movement of empty containers, and a bar bar is installed next to the feeding belt conveyor in front of the empty containers being transported by the feeding belt conveyor. The movement of the empty container is stopped in a slip state as a receiver under the above-mentioned supply port, and after receiving the weighed object, the bar bar is removed from the moving space to eliminate the stoppage. Since each container is equipped with a remote control type receiver standby stopper that allows the container to move, the empty container I mounted on the base end of the return belt conveyor 3 is blocked by the empty container standby stopper 8 and is in a slip state. After waiting on the tip of the returning belt conveyor 3, the empty containers are guided one by one onto the feeding belt conveyor 2 by the elevator 4, and the empty containers are placed on the receiving stopper 10.
The process of waiting under the supply port 1 in a slip state blocked by the conveyor, and during this waiting, receiving the weighed items, etc., and then moving onto the tip of the feeding belt conveyor 2 is performed continuously. In this way, the present invention places a single worker at a position facing both the base end of the returning belt conveyor and the leading end of the forwarding belt conveyor, thereby allowing the container to be placed under the supply port for weighed items, etc. Continuously repeats a series of operations such as feeding the container into the container that has been supplied with weighed items in the same department, returning it to hand, and re-feeding the container below the above-mentioned supply port after taking out the stored items. And it can be done reliably,
This has the effect of greatly contributing to labor savings in this type of work.
