Description

[Detailed explanation of the idea] The present invention relates to a sorting device.

In a conventional sorting device, for example, as shown in FIG. 1, sorting is carried out by selectively discharging cargo from two conveyor lines 1 and 2 to a number of chutes 3 and 4 using a discharging device (not shown). In this case, primary sorting is performed by a material handling device (not shown) at positions A and B on the transport lines 5 and 6, which are higher than the transport lines 1 and 2. That is, the conveyance lines 1 and 2 correspond to the major classification of sorting, and the chute 3 and 4 correspond to the minor classification of sorting. Note that 7 and 8 are shipping spaces. However, in such a conventional sorting device, if the cargo supplied to the transport lines 5 and 6 is temporarily biased toward one of the major classifications, an excessive amount of cargo is fed to one transport line 1, and the other transport line 1 is overloaded. Although the transport line 2 has sufficient capacity, one of the transport lines 1 is saturated and cannot handle the cargo, and the transport line 5,
This resulted in a situation where the supply of cargo to No. 6 had to be stopped, resulting in poor sorting efficiency. Therefore, conventionally, as seen in Japanese Utility Model Application Publication No. 56-8822, for example, a loop-shaped main conveyor device is arranged, and a baggage receiving conveyor group or a baggage receiving conveyor group is installed on the side of the long parallel part of this main conveyor device. A group of chutes is arranged, and the baggage group is transferred to the main conveyor device via the baggage receiving conveyor group, and is sorted and taken out to the baggage receiving chute group while being conveyed by the main conveyor device. However, according to this conventional type, the conveyor group and chute group are installed side by side, making the material handling area complicated, and since the main conveyor device is loop-shaped, the overall structure including the drive device is complicated. Become. Furthermore, if you try to carry out major classification and small classification all at once, the baggage may have to go around once on a loop path, which not only makes it impossible to sort quickly, but also prevents the main conveyor from accumulating a lot of baggage. requires large driving force. As mentioned above, since the cargo handling section is complicated, when a large number of packages are sorted into a specific sub-sorting area, there is not enough space to stack the sorted packages. Regarding this space problem, for example,
As seen in the 143666 publication, by lifting a part of the chute, the lower part can be used effectively. However, even if the baggage receiving chute group of Utility Model Application Publication No. 56-8822 is made into a lifting type,
Problems such as the complexity of the overall structure and the fact that the baggage has to be rolled around almost once will remain as unsolvable problems.

The present invention solves the above-mentioned conventional drawbacks, and aims to provide a sorting device that has a simple structure, can efficiently sort, and can effectively utilize the space below the chute. .

In order to achieve the above object, the sorting device of the present invention has two conveyance lines arranged in parallel between a pair of shipping spaces facing each other with a predetermined interval, with the conveyance direction being the same. , a pair of chutes for transferring cargo from each transport line to the pair of shipping spaces are connected at appropriate intervals in the longitudinal direction of the transport line, and a discharging device is provided for selectively discharging cargo from each transport line to the chute. , the pair of chute is composed of a first chute extending toward one shipping space and a second chute extending toward the other shipping space passing under an adjacent conveyance line, and the first chute is vertically oscillated. The second chute is configured to be movable, and the second chute is composed of a fixed upper half and a lower half that is vertically swingable with respect to the upper half, and the first and second chute are arranged to be movable. This configuration includes a lifting device for lifting the parts.

According to this configuration, since the two conveyance lines to which cargo is supplied from one side end have the same conveyance direction, the structure is simple, and from either conveyance line there is no connection between the first chute or the second chute.
Since the cargo can be sent to both shipping spaces via the chute, it is possible to quickly sort the cargo without stagnation, and both conveyance lines can be operated at full capacity at the same time to perform efficient cargo sorting. Also, although the number of chutes is greater than before, the bottom end of the chutes can be lifted when not sorting, so this space can be used effectively, such as by storing luggage.

An embodiment of the present invention will be described below based on the drawings. In Figures 2 and 3, 9 and 10 are a pair of shipping spaces 1 facing each other with a predetermined interval.
The conveyor lines 9 and 10 are arranged parallel to each other between the conveyor belts 1 and 12, and the conveyor lines 9 and 10 are configured by belt conveyors using, for example, steel belts so that the conveyance direction is the same. 13,14
is a carry-in line connected to the upper side of the transport lines 9, 10, and cargo is supplied to these carry-in lines 13, 14 from trucks or the like stopping at cargo collection spaces 15, 16. Reference numerals 17a and 17b are auxiliary carry-in lines installed in parallel with the carry-in lines 13 and 14, one carry-in line 17a is supplied with cargo from a truck or the like stopping at the space 18, and the other carry-in line 17b is Luggage is supplied from the second floor. The loading lines 13, 14 and 17
a and 17b are constituted by belt conveyors using, for example, steel belts, and guide plates 19 are installed at merging parts and the like. The transport lines 9 and 10 include the shipping spaces 11 and 12.
A pair of chutes 20a, 2 for transferring cargo to
0b, 21a, and 21b are connected, and a plurality of pairs of the chute 20a, 20b and 21a, 21b are installed at appropriate intervals in the longitudinal direction of the conveyor lines 9, 10. These pairs of shoots 20a, 2
0b, 21a, 21b, one shipping space 1 without passing under the adjacent transport lines 9, 10.
First chute 20a, 21a extending to the 1st, 12th side
is rotatably supported at its upper end, and also has a second chute 20 extending to the other shipping space 12, 11 side passing under the adjacent transport lines 10, 9.
b, 21b are divided into two parts, with the upper half fixed and the upper end of the lower half rotatably supported by the support member 22 or 23. These first chute 20a, 21a and second chute 20b, 2
When not in use, the lower half of 1b can be hoisted up by hoisting devices 33 and 34 attached to the ceiling 24, as shown by the imaginary line in FIG. The second chutes 20b, 21b are provided with a large number of free rollers, and a free roller conveyor 27 is connected to the lower ends of the chutes 21a, 20b corresponding to the shipping space 12. This free roller conveyor 27, as shown in detail in FIG. 4, is for merging the loads that have passed through the chutes 21a and 20b. Furthermore, a free roller conveyor 26 is similarly connected to the lower ends of the chutes 20a and 21b corresponding to the shipping space 11. A plurality of delivery devices 28 and 29 are installed on the conveyance lines 9 and 10 to selectively deliver cargo to the chutes 20a, 20b, 21a and 21b. The dispensing devices 28 and 29 select a package by detecting a label affixed to the package, for example, and have a well-known configuration, so a detailed explanation will be omitted. In addition, in FIG. 3, 30 is a floor, 31 is a frame on which the transport lines 9 and 10 are installed, 32 is a column, and 3
3 and 34 are shot 20a and 20 for some reason.
This is a mistake to take out the baggage that has not been delivered to 21b, 21a, and 21b.

Next, the operation will be explained. The cargo supplied to the carry-in line 13, 14 or 17 is transferred to the carry-in line 1.
3, 14, 17 to the conveyor lines 9, 10, and while being conveyed on the conveyor lines 9, 10, a sorting device 28,
Shoot 20 detected in 29 and corresponding to the classification
It is paid out to a, 20b, 21a, and 21b. At this time, chutes 20a and 2 are sent from each transport line 9 and 10 toward both shipping spaces 11 and 12.
0b, 21a, and 21b are provided, and since the same classification of cargo is delivered to the same place no matter which transport line 9 or 10 is on it, both transport lines 9 and 10 can be fully operated at the same time. This allows for efficient sorting.
Thus, the shoots 20a, 20b, 21a, 21
The cargoes delivered to predetermined positions according to their classification through free roller conveyors 26 and 27 are carried out by trucks or the like that stop at shipping spaces 11 and 12. After completing the sorting work,
First chute 20a, 21a and second chute 2
The lower halves of 0b and 21b are lifted up by lifting devices 33 and 34. As a result, the chute 20a,
Luggage and the like can be stacked below the lifted portions of 20b, 21a, and 21b, allowing effective use of space.

As explained above, according to the present invention, since the two transport lines to which cargo is supplied from one end side have the same transport direction, the overall structure including the drive device can be simplified, and By separating the cargo handling area and the sorting area, congestion can be eliminated. In addition, parcels of the same classification can be delivered to the same location from either transport line, making it possible to quickly sort items without causing them to accumulate, and allowing both transport lines to operate at full capacity at the same time. Therefore, sorting can be performed very efficiently. Furthermore, although the number of chute is increased compared to the conventional one, by lifting the chute with a lifting device, the space below the chute can be used effectively when sorting is not being performed.
