Description

[Detailed description of the invention] The present invention relates to an automatic sorting device.

As an example of automatic sorting equipment, for example,
There is a configuration as disclosed in Japanese Patent No. 52-101570. That is, there is a configuration in which a secondary sorting conveyor is provided, and a plurality of inclined chutes are provided on the side of the secondary sorting conveyor and orthogonally connected to the secondary sorting conveyor. In this configuration, the code of the baggage conveyed by the secondary sorting conveyor device is detected, and when the baggage is opposed to the corresponding secondary sorting conveyor, the slats are tilted to transfer the baggage onto the chute. I'm sorting things out. The sorted cargo is then loaded onto trucks, which constitute a truck terminal. However, in such an automatic sorting device, efficient sorting cannot be performed because there is only one secondary sorting conveyor. Additionally, truck terminals typically have buildings that are raised in the middle, creating dead space.

To solve these problems, for example, a configuration disclosed in Japanese Patent Application Laid-Open No. 11459/1983 has been proposed. That is, the sorting conveyor is formed with an upper running section and a lower running section, and a sorting chute is provided orthogonally connected to one side of these running sections, and a diverter is provided on the other side of both running sections, facing each sorting chute. has been established. According to this conventional type, the dead space can be effectively utilized to arrange both running sections for sorting on the upper and lower sides, and furthermore, the upper and lower running sections can perform efficient sorting work.

By the way, according to the configuration of the above-mentioned Japanese Patent Application Laid-open No. 53-11459, at the end of the sorting chute group,
Empty boxes that can be freely transported are facing each other on a real box transport conveyor, and workers are loading the cargo that has been sorted and slid through the sorting chute into the empty boxes. Therefore, workers are responsible for a large number of sorting chutes, which makes it difficult for workers to load cargo. In addition, when the loading platform of a truck is placed directly opposite the end of a group of sorting chutes, either directly or via an intermediate conveyor system, loading operations cannot be carried out easily. Loading operations using such methods will not be possible. To deal with this, for example, adjacent sorting chutes can be merged in a manner similar to the configuration in which the secondary sorting coating conveyor and the secondary sorting conveyor are merged, as disclosed in the aforementioned Japanese Patent Laid-Open No. 52-101570. It is conceivable to reduce the number of chute ends. However, in this case, there is a risk that the load may become clogged at the merged portion of both sorting chutes, and furthermore, there is a risk that the load may not be conveyed smoothly in the lower sorting chute, which has a smaller inclination angle.

It is an object of the present invention to provide an automatic sorting device that can easily and quickly deal with the situation where loads become clogged at the merging completion section, and that can always smoothly move loads even in lower chute bodies with small inclination angles. It is in the point of doing.

In order to achieve the above object, the automatic sorting device of the present invention has an upper conveyor device and a lower conveyor device arranged above and below, and an inclined chute device that is orthogonally connected to one side of both conveyors.
Furthermore, a load unloading device is provided on the other side of both conveyors facing each of the inclined chute devices, and the inclined chute device is connected to the upper conveyor device and has a first chute body having a smooth conveying surface, and a lower conveyor. a second chute body connected to the device and having a low friction conveyance surface; the second chute body includes a first half chute portion parallel to the first chute body in plan view; and a first chute body inclined toward the first chute body. do,
It is composed of this first chute body and a second half chute portion that gradually merges with each other, and the merged portion of both chute bodies is set at a height that can be accommodated by a worker on the floor.

According to this configuration of the present invention, the load delivered to the first chute body slides on a smooth surface with a large inclination angle, and the load delivered to the second chute body slides on a smooth surface with a large inclination angle, and the load delivered to the second chute body has a small inclination angle but is subject to frictional resistance. After moving on a low friction surface with little friction, it joins the first chute body. When cargo becomes clogged at the merge completion section, workers on the floor can clear the jam.
As mentioned above, the load discharged from the lower conveyor device to the second chute body joins the first chute body, and since only the first chute body corresponds to the truck, the load is placed behind the loading platform of this truck. can form a space. Therefore, by utilizing this space, the cargo of the first chute body can be easily loaded onto the truck loading platform, and the loading operation can also be carried out using a forklift vehicle, a dolly, or the like.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a frame, on the top of which a machine frame 2 is installed, and on this machine frame 2, an upper conveyor device 3 and a lower conveyor device 4 are conveyed in the same direction (although they may be in opposite directions). They are arranged above and below. Reference numeral 5 designates inclined chute devices which are orthogonally connected to one side of both conveyor devices 3 and 4, and a plurality of inclined chute devices are arranged at predetermined intervals in the length direction of both conveyor devices 3 and 4. This inclined chute device 5 includes a first chute body 6 connected to the upper conveyor device 3;
Second chute body 7 connected to lower conveyor device 4
It is supported on the floor 9 side via a plurality of supports 8. The second chute body 7 includes, in plan view, a front half chute portion 7A parallel to the first chute body 6, and a rear half chute portion that is inclined toward the first chute body 6 and gradually merges with the first chute body 6. It is composed of 7B. Here, the parallel state is such that the first chute body 6 is located on the upstream side with respect to the conveyance direction by both conveyor devices 3 and 4. The conveyance surface (upper surface) of the first chute body 6 with a large inclination angle is formed by a smooth surface, and the conveyance surface of the second chute body 7 with a small inclination angle is formed into a low friction surface by, for example, a group of rollers. In the case of a roller group, the idling roller group in the bending portion 10 extending from the end of the first half chute portion 7A to the beginning end of the second half chute portion 7B of the second shute body 7 is formed by a tapered roller.
As a result, the load 11 on the second chute body 7 side gets into the first chute body 6 at a large angle and accelerates. The confluence of the two chute bodies 6 and 7 is formed at a step H, so that the first chute body 6
The load 11 that has flowed through rotates and passes through the second chute body 7.
side to prevent further clogging. At the same time, the load 1 is transferred from the second chute body 7 to the first chute body 6.
1 will flow smoothly. The merging portion 12 of both the chute bodies 6 and 7 is set at a height H that can be accommodated by a worker on the floor 9, for example, 1500 mm or less. A relay conveyor device 13 is disposed continuously at the terminal end of the first chute body 6, and the terminal end of the relay conveyor device 13 faces the stop 14. 15 is a truck, and 16 is a forklift vehicle (or transport vehicle). Opposing each chute body 6, 7 of the inclined chute device 5, on the other side of both the conveyor devices 3, 4, a load unloading device 17, 1 is provided.
8 is provided.

The code of the load 11 conveyed by the upper conveyor device 3 is detected, and the load is discharged to the first chute body 6 by the load discharge device 17 at a predetermined location. The delivered cargo 11 is the first
It slides on the smooth surface of the chute body 6 and is passed to the intermediate conveyor device 13. In addition, the lower conveyor device 4
Similarly, the cargo 11 transported by the cargo discharging device 18 is discharged onto the second chute body 7. The load 11 discharged onto the second chute body 7 is transferred to the first half chute part 7 which forms a low friction surface.
It slides on the first chute body 6, then accelerates at a large angle at the bending part 10 and enters (joins with) the first chute body 6. When the loads 11 are alternately delivered to both the chute bodies 6 and 7, the loads 11 slide without being interfered with each other and are transferred to the intermediate conveyor device 13. However, in some cases, they may be paid out at the same time or almost at the same time. At this time, the two loads 11 come into contact with each other at the merging section, and the two loads 11 slide together as one, resulting in a blockage in the merging completion section 12, as shown by the imaginary line in FIG. At this time, the merge completion section 12
Since the height H is set at a height that can be handled by the worker on the floor 9, the worker can easily and quickly separate the two loads 11 from the front and back. It can be passed to the 13th side. The load 11 that has reached the end of the intermediate conveyor device 13 is loaded onto the truck 15 by hand by an operator. Second
As shown in the figure, the truck 15 is stopped so that one side thereof faces the relay conveyor device 13. Therefore, the part of the floor 9 facing the other side of the track becomes a wide space. Using this space, the load 11 is transferred from the intermediate conveyor device 13 to the truck 15.
The cargo 11 can be loaded easily, and the cargo 11 can also be loaded using a forklift vehicle 16 or the like.

According to the present invention having the above configuration, the load delivered to the first chute body can smoothly slide on a smooth surface with a large inclination angle, and the load delivered to the second chute body can slide smoothly on a smooth surface with a small inclination angle. However, after moving smoothly on a low-friction surface with little frictional resistance, it can join the first chute body. As a result, the delivered cargo can be moved reliably and smoothly at all times without stopping on the way. Even if the loads from both chute bodies become jammed at the merging completion part, the operator can easily and quickly correct the problem by setting the height of the merging completion part.

Further, according to the present invention, the dead space of the building can be effectively utilized to arrange the conveyor devices one above the other, and efficient sorting work can be performed using the upper and lower conveyor devices. In addition, it can be expected to have twice the sorting capacity as the single format while occupying almost the same platform area. Furthermore, during off-peak hours, only one conveyor can be operated, which reduces electricity costs. Furthermore, by making them independent in terms of control, it is possible to respond quickly in the event of a downtime. Furthermore, by employing the inclined chute device having the above configuration, the load discharged from the lower conveyor device to the second chute body joins the first chute body, so that the load that corresponds to the truck etc. is the first chute body.
Since there is only a chute body, a large space can be created at the rear of the truck bed. Using this space, it is possible to easily load the cargo that has reached the end of the first chute body onto the truck loading platform, and it is also possible to easily perform loading work using a forklift vehicle, a trolley, etc. can.
