Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transport device such as a recovery bottle.
[0002]
[Prior art]
Conventionally, for example, collected bottles are automatically sorted by size, type, and color for reuse, but the sorting order is first sorted by size (size) and then sorted by size. Many of the recovered bottles are then sorted by type or color. As shown in FIG. 3, a pair of first conveyors 1 and 1 are installed in a flat or reverse C shape with a predetermined interval G as a sorting device that sorts according to the size of the size. Some downstream of the conveyor is provided with a second conveyor 2 having a width substantially equal to the conveyor. The applicant of the present application previously provided the first transport conveyors 1 and 1 in multiple stages for sorting by the size of the collection bottle A etc., and widened the interval between the first transport conveyors located at the top. In addition, a sorting and conveying device such as a collection bottle was proposed in which the gap between the lower conveyors was sequentially set to a narrow interval. According to this transport device, when the recovered bottle is supplied onto the first transport conveyor on the uppermost stage, the one larger than the distance between the transport conveyors is transported by the transport conveyor as it is, and the second transport conveyor on the downstream side. The small bottles are dropped on the lower conveyor, and the smaller ones are further dropped on the lower conveyor, and are then moved by the second conveyor 2 installed on the downstream side. It is transported to a sorting device that sorts by the type and color of the downstream stage.
[0003]
However, the recovery bottle A has a wide variety of shapes, and may fall completely and reliably due to the gap G between the first transfer conveyors 1 and 1 and may not be sorted. For example, the shape of the recovery bottle is such that the upper half is larger than the interval of the first conveyor and the other half is smaller than this interval. In such a bottle, as shown in FIG. Even if it moves in a suspended state in the gap between the conveyors 1 and 1 and receives an upward action from the second conveyor 2 between the lower end of the first conveyor and the second conveyor 2 If the lower half of the bottle is heavier than the upper half, the bottle cannot move onto the second conveyor and stagnate at this point. Therefore, it becomes an obstacle to the smooth conveyance of the collection bottle A by the first conveyance conveyors 1 and 1.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a transfer device that can smoothly and reliably transfer a collection bottle or the like from a pair of first transfer conveyors provided with a gap of a predetermined interval to a second transfer conveyor. .
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the features of the transport device such as the collection bottle of the present invention include a pair of first transport conveyors installed at a predetermined interval in the horizontal direction, and a downstream of the pair of first transport conveyors. And a second conveying conveyor having a predetermined width at a position corresponding to the interval of the first conveying conveyor, the conveying device having a predetermined width within the interval of the pair of first conveying conveyors. A third conveyor is provided on the downstream side so as to be inclined upward toward the tip of the second conveyor.
[0006]
The pair of first conveyors being installed in the horizontal direction means that there is a step in the vertical direction, and both conveyors have a flat positional relationship in order to transport recovery bottles and the like. Some include the ones that are installed in a reverse C shape and the collection bottles naturally move to the center and flow.
[0007]
According to the present invention, the recovery bottles and the like are conveyed by the first conveyor, lifted by the third conveyor, and can be smoothly moved onto the second conveyor on the downstream side.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a pair of transfer conveyors (first transfer conveyors) 1 and 1 are installed with a predetermined gap G in the horizontal direction. A second conveyor 2 is installed on the downstream side of the pair of first conveyors. As shown in FIG. 1, the width of the second transfer conveyor 2 is the same as the width of the pair of transfer conveyors 1 and 1, but this width is at least a position corresponding to the distance between the pair of first transfer conveyors. It is sufficient if the width is such that the collected bottle A can be smoothly received and reliably conveyed.
[0009]
By the way, the characteristic of this invention exists in the place which installed the 3rd conveyor 3 in the downstream in the said space | interval of a pair of 1st conveyance conveyors in the conveying apparatus of an above-described structure, Inclined upward toward the tip of the two conveyors 2.
[0010]
Next, the operation of the present invention will be described.
[0011]
In FIG. 2, when a state of moving in a suspended state occurs in the gap G between the first transfer conveyors 1 and 1 like the collection bottle A on the left side, according to the conventional example, as shown in FIG. Between the lower end of the transfer conveyor and the second transfer conveyor 2, even if it receives an upward action from the second transfer conveyor 2, it cannot move on the second transfer conveyor because the lower half of the bottle is heavy. . However, in the present invention, the recovery bottle A is conveyed rightward by the first conveyor 1, 1 and the lower half of the recovery bottle A is recovered by the third conveyor 3 like the recovery bottle A shown on the right side. Can be lifted and smoothly moved onto the second conveyor 2 of the next stage.
[0012]
In addition, the installation angle and speed of the 3rd conveyor 3 can also be made variable.
[0013]
【The invention's effect】
Since the present invention is implemented in the form as described above, even if the recovery bottle or the like is transported in a suspended state in the gap between the pair of transport conveyors, the second conveyor of the rear stage is transported by the third conveyor. Can be connected smoothly and reliably on the conveyor.
