Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a container-type conveying device that weighs articles to be weighed while the container containing the articles to be weighed is being conveyed by an endless conveying device.

<Prior Art> Conventionally, a container-type conveying device has roller receiving parts 4 provided on both end surfaces of a container 2, as shown in FIG.
A roller 8 protruding from the chain 6 is fitted, and the container 2 is moved along the rail 10 as the chain 6 moves.
When the container 2 was placed on the weighing rail 12 provided halfway along the rail 10, there was something to be weighed. Note that a roller 14 is provided on the end face of the container 2 and rolls on the rail 10 and the measuring rail 12.

<Problems to be Solved by the Invention> However, in the conventional apparatus described above, even while the container 2 is being conveyed on the weighing rail 12, the container 2 is moved with a certain degree of freedom via the rollers 8. Since it is connected to the chain 6, highly accurate measurement is not possible due to the effects of friction and the like.

<Means for solving the problem> A conveyance/weighing device is provided midway through the transfer path of the container to be weighed to measure the weight of the container to be weighed while conveying this transfer path, and a part of the device is parallel to the above-mentioned path. An endless conveyance device that runs at the same speed as the above-mentioned conveyance is arranged on the side of the above-mentioned path, and an elevating member is attached to this endless conveyance device so as to be movable in the vertical direction. A frame-like body that is disposed in a non-contact state and that supports a support member extending laterally from the object container to be weighed by supporting it from below is coupled to the lifting member, and the frame-shaped body is connected to the endless conveyance device. A roller that rolls on a guide rail shape that is installed in parallel is provided on the elevating member so that the elevating member changes its height position according to the height position of the roller, and the height of the guide rail is is set at a height such that the frame-shaped body is located downwardly away from the support for the container to be weighed placed on the transport device in the part corresponding to the transport and weighing device, and In part, the height of the container for objects to be weighed, which is supported by the frame-like body, is selected to be higher than the top surface of the conveying/weighing device.

<Function> According to the present invention, in a portion other than the weighing and conveying device, the elevating member connected to the roller is in a raised state, the frame-like body is also raised, and the support protruding from the container is in a raised state. is supported by. On the other hand, since the elevating member is also connected to the endless conveyance device, the container is conveyed as the endless conveyance device advances.

Further, at the position of the weighing/conveying device, the elevating member descends as the rollers descend, thereby also lowering the frame-shaped body, and the container is placed on the conveying/weighing device. When the elevating member further descends, the support member separates from the frame-shaped body. At this time, the container is in a non-contact state with the frame-shaped body and is separated from the endless conveyance device, so that the endless conveyance device has no influence on the weighing of the container by the conveyance and weighing device.

<Example> In this example, as shown in FIG. 1, a weighing chain conveyor 20 is provided as a conveying and weighing device. This weighing chain conveyor 20 is provided within a predetermined transfer route, and has two chains 2.
2, 22, load cell 24, platform 26, pulley 2
It consists of 8, 28...

Chains 30, 30 as conveying devices are stretched on the sides of the weighing chain conveyor 20 so that at least a portion thereof extends along the transfer route. The chains 30, 30 move at the same speed as the weighing chain conveyor 20. An elevating member 32 is connected between the chains 30, 30 so as to connect them. An elevating member 34 is fitted onto the outside of the elevating member 32 so as to be movable in the vertical direction along the elevating member 32.

A frame-shaped body 38 located within a predetermined transfer path is coupled to the elevating member 34 via a support rod 36 . V-shaped supports 40, 40, 40, 40 are provided at the four corners of the upper surface of this frame-like body 38, and a container 42 is disposed within this frame-like body 38.
Supports 44, 44, 44, 44 projecting outward from the four corners of the outer surface of 2 are the supports 40, 4.
It is supported by 0,40,40. In addition, 46 is a discharge gate, which is provided to be able to open and close the lower end opening of the container 42.

The lifting member 34 is coupled to a roller 48 located above the chains 30, 30. This roller 48 rolls on a guide rail 50, which guides the chains 30, 30.
It is placed above and along this line. This guide rail 50 has a section 50a excluding the infeed side and the outfeed side of the weighing chain conveyor 20.
The section 50b corresponding to the platform 26 of the chain weighing conveyor 20 is at a second height position, and the section 50 connecting the sections 50a and 50b is located at a second height position.
c and 50d are downwardly inclined and upwardly inclined. 1st
As shown in FIG.
2 is selected to be lifted up so that it is located above the mounting table 26. Similarly, the second height position is selected such that the frame body 38 is lowered such that the support 44 is separated from the support base 40 and the container 42 is placed on the platform 26, as shown in FIG. ing.
In this state where the frame-like body 38 is lowered, the container 42 is not in contact with the frame-like body 38 at all.

The operation of this embodiment will be explained next. The container 42 is supplied with articles at the article supply position. In this state, the rollers 48 are in section 5 of the guide rail 50.
Since it is at 0a, the elevating member 34 is rising,
Along with this, the frame-shaped body 38 also rises, and the container 42 is lifted up. Furthermore, since the elevating member 32 presses the elevating member 34 as the chains 30, 30 advance, the container 42 is transported together with the frame body 38.

Eventually, when the roller 48 rolls on the downwardly inclined section 50c of the guide rail 50, the elevating member 34 descends accordingly, and the frame body 38 and container 42 descend and are placed on the platform 26 of the weighing chain conveyor 20. A container 42 is placed thereon. Then, as shown in FIG. 2, when the roller 48 reaches the section 50b of the guide rail,
Only the frame-shaped body 38 is further lowered, and the support tool 44 is detached from the support stand 40. This allows the container 42
is in a state where it is separated from the chain 30. In this state, the load cell 24 performs measurement. At this time, the container 42 advances at the same speed as the chain 30.

Eventually, when the roller 48 begins to climb the ascending slope section 50d, the frame-shaped body 38 rises and the support 44 comes into contact with the support base 40. Furthermore, the frame-shaped body 38 continues to rise, and when the roller 48 reaches the section 50a,
The container 42 is completely lifted off the platform 26,
The articles are transported to the next article sorting position in the same manner as described above.

In the above embodiment, only one container 42, one frame body 38, etc. are shown, but with appropriate intervals,
A plurality of each may be provided. In addition, the elevating member 3
A roller 48 and a support rod 36 are provided on the elevating member 34 provided on the outside of the elevating member 32. However, conversely, the elevating member 34 is connected to the chains 30, 30, and the elevating member 32 is provided with the supporting rod 3.
6. A roller 48 may be provided. Furthermore, although the chain weighing conveyor 20 is used, a belt weighing conveyor may be used instead. Further, although chains 30, 30 are used, a cord such as a belt may be used instead.

<Effects> As described above, in the container-type weighing device according to the present invention, when the roller is in a position other than the conveying and weighing device, the roller is raised, so the elevating member also rises, and the frame-like body accordingly rises. The container is raised and supports the container support, which raises the container higher than the weighing transfer device. When the roller reaches the position of the conveying and weighing device, the roller is lowered and the elevating member is also lowered. Along with this, the frame-like body also descends, and the frame-like body separates from the container support and rests on the weighing and conveying container. At this time, the frame-like body is in a non-contact state with the container. Therefore, the container is completely separated from the endless conveyance device during measurement by the conveyance and weighing device, allowing highly accurate measurement without being affected by friction or the like.
