Abstract

PURPOSE:To prevent an impact to goods so as to make the sorting of the goods smooth with the use of a shockless sorting device for parcels or the like, by arranging delivery conveyers at a height substantially equal to that of a transfer conveyer, and by providing diverters at sorting positions while connecting inclined roller conveyers to the delivery conveyers. CONSTITUTION:When goods 7 set on a rectilinear conveyer 1 is fed from an inlet part 6 to predetermined sorting positions by way of a curved conveyer 2, the associated diverters 5a through 5e are operated so as to pay out the goods to be sorted to delivery conveyers 3a through 3b which are laid at a height substantially equal to that of the diverters 5a through 5e so that the goods 7 are shifted onto the delivery conveyers 3a through 3e. The goods 7 are then fed toward roller conveyers 4a through 4e, and after running down the roller conveyers 4a through 4e, they are stopped, making contact with stopper rollers 4a through 4e. With this arrangement, it is possible to sort the goods 7 with no shock being applied thereto.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a non-impact sorting device, and more particularly to a non-impact sorting device that sorts various packages such as postal parcels without applying impact.

[Prior Art] As a conventional non-impact sorting device of this type, one shown in FIG. 5 has been used.

In FIG. 5, the cargo 56 to be sorted is
It is loaded onto the van 52a and moved. A plurality of buns 52a are attached to an endless drive chain 51 at predetermined intervals, and as the drive chain 51 rotates in a direction perpendicular to the paper, the buns 52a also circulate in the direction perpendicular to the paper. do. When the pan 52a is on the upper side of the drive chain 51 during movement, that is, when the pan 52a is on the upper side of the drive chain 51,
When it is in the position shown by , it is on the outward journey carrying the cargo 56, and when it is below the drive chain 51, that is, in a suspended position as shown by the reference numeral 52b, it is in the process of sorting the cargo 56. This is the return trip after completing the work.

The non-impact sorting device has a skeleton composed of frames 53a to 53d, and is covered by a housing 54. In addition, the non-impact sorting device is provided with a chute 55 on the side, and a plurality of containers 5 are placed at the bottom of the chute 55.
7 is placed.

Which container 5 among these plurality of containers 57
As will be explained next, the solenoid 58 is selectively activated to determine whether the materials should be dropped into the container 7, thereby performing sorting, which is the purpose of the work.

In the outgoing journey of the van 52a described above, the loaded baggage 56
When the solenoid 58 is actuated at the position of the container 57 where the container 57 is to be dropped, the lever 59 acts on the bun 52a. The van 52a is tilted upward to the right (as shown by the symbol 52-1).
5), and the loaded cargo 56 is transferred to the chute 55. Baggage 56 transferred to chute 55
The container 5 slides on the inclined chute 55.
It falls to 7. At this time, sorting work is performed by selecting which container 57 to drop. [Problems to be Solved by the Invention] The above-described conventional non-impact sorting device transfers the cargo 56 onto the chute 55 by rapidly tilting the van 52a, and then slides the cargo 56 on the chute 55 and drops it into the container 57. When transferring cargo 5 from van 52a to chute 55,
6 and is accelerated as it slides down the chute 55, giving an extremely large impact to the cargo 56 when it falls from the chute 55 to the container 57.

Therefore, if the baggage 56 is made of glass, chinaware, or other items that are susceptible to impact, there is a drawback that the baggage 56 may be damaged during the sorting work.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems, and allows the sorting work to be carried out without giving any impact to the cargo by smoothly transferring the cargo from the conveyor to the sorting destination conveyor. In order to achieve this purpose, a conveyor that carries sorted baggage and moves, multiple sorting destination conveyors installed at almost the same height as the conveyor, and sorted baggage that the conveyor moves. It is equipped with multiple diverters that sort and transfer the sorted items to the sorting destination conveyor, and is connected to the diverters to transfer the sorted items, and is installed at an angle to prevent the transferred sorted items from flowing backwards. A roller conveyor is also provided.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a plan view showing an embodiment of a non-impact sorting device according to the present invention. FIG. 2 is a side view showing an embodiment of the non-impact sorting device according to the present invention.

In FIG. 1, a rotating endless belt conveyor is composed of a linear conveyor 1 and a linear conveyor 1a, and a curved conveyor 2 and a curved conveyor 2a. A predetermined range of the linear conveyor 1 is defined as an input section 6,
The baggage 7 is placed on the linear conveyor 1 from this input section 6. When the baggage 7 is placed on the linear conveyor 1, the baggage 7 starts moving rightward in the drawing, but the baggage 7 does not reach the predetermined input section 6.
The sorting destination code of the baggage 7 is sent to a control device (not shown) using a keystroke or a barcode reader while the baggage 7 is within the range of the sorting destination. Activate one of the following.

For example, when sorting the luggage 7 at the position of the diverter 5a, the movable plate 5a-1 is rotated counterclockwise. The baggage 7 that has moved on the linear conveyor la is moved to this movable plate 5a.
-1, is slid as shown by reference numeral 7a, and is transferred to the sorting destination conveyor 3a. Sorting destination conveyor 3
a is installed at almost the same height as the diverter 5.

Therefore, the baggage 7 is smoothly transferred to the destination conveyor 3a, and no shock is applied to the baggage 7.

When the cargo 7 is transferred to the sorting destination conveyor 3a, the sorting destination conveyor 3a is driven for a predetermined time, that is, the time until the cargo 7a is transferred to the roller conveyor 4a. Baggage 7a is transferred to roller conveyor 4a. After that, the roller conveyor 4a transports the roller conveyor 4a to the end of the roller conveyor 4a.

The roller conveyor 4 is inclined to an extent that prevents the baggage 7a from flowing backwards, and therefore the baggage 7a continues on the roller conveyor 4a until it comes into contact with the stopper roller 4a-1 and stops.
It moves on the roller conveyor 4a and is temporarily stored at the end of the roller conveyor 4a.

In this way, the baggage 7 is placed at the end of the roller conveyor 4a.
By moving the roller conveyor 4a, the packages 7 are sorted, and the packages 7 transferred to the end of the roller conveyor 4a are carried out manually or by a manipulator.

[Effects of the Invention] As explained above, the present invention provides a conveyor that carries cargo to be sorted and moves, a plurality of destination conveyors that are installed at almost the same height as the conveyor, and a sorting system that moves the conveyor. There are multiple diverters that sort the cargo and transfer it to the sorting destination conveyor, and the diverter is connected to the diverter to transfer the sorted cargo, and is installed at an angle to prevent the transferred sorted cargo from flowing backwards. Since the conveyor is equipped with a roller conveyor, the cargo can be transferred smoothly from the conveyor to the sorting destination conveyor, and the sorting work can be performed without impacting the cargo.
