Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor device for transporting items such as mail in containers, and particularly for sorting large, irregularly shaped envelopes and mail with banding according to their destination. relates to a conveyor device.

Conventionally, the work of sorting mail and other conveyed items according to their destination has been done manually, or in the case of some regular-sized mail, sorting has been done using a conveying device. There is no transportation device to satisfactorily sort large, irregularly shaped envelopes other than the Shinkai standard size, wrapped newspapers, and other mail items, and manual sorting relies solely on manual labor, which is complicated and extremely inefficient. It was efficient.

The present invention was devised by focusing on these drawbacks, and it is capable of automatically sorting and conveying non-standard-sized envelopes and mail items with banding according to their destinations, and also sorting and conveying mail items destined for the same destination. The purpose of the sorting conveyor device is to accumulate and efficiently sort Otsuki's mail, etc. in a short time. It is.

Next, regarding drawings showing embodiments of the present invention, H! ? , reveal.

In 2a), it is moved at high speed by a drive roller (8) that rotates faster than the drive roller (6) in the straight portion (1a) (see FIG. 3). Container 69 in input position (A)
For compartment CHI, from the sorting input device (+1) to -
Correspondence mail (goods) will be invested. This is synchronized when a compartment (c) of a container (31) that matches the destination information entered according to the postal code approaches, a proximity detector (not shown) detects the marker 0) of the compartment e3ft. The holding frame (G) of the loading machine 09 moves in synchronization with the container C31) and loads it into the designated compartment <l. The container containing the designated mail (goods) in each compartment (G) advances from the end of the input position (A) to the upwardly inclined or vertically raised position 0, and then moves to the raised position (1).
3) following the guide rail (4) and rotating faster than the input position, or a drive mechanism using a drive chain 03 that fixes the pin θ◇, or a rack.
This rise in height Iff (
H) and discharge position f which is above the input position
Proceed to C). Similar to input position (A), discharge position 1
'f Container 01) in (C) moves at a constant speed in a connected state by a drive roller (6) and a brake roller (7) in each opposing linear part (IC),
), the drive roller (2C) rotates faster than the drive roller (6) in the straight section (IC).
8), it moves at high speed (see Figure 3). Ejection position 0
The stored mail (B) is discharged from the container 0η located in the container 0η, and when each compartment 0 of the container 01) approaches the discharge chute (2) from which the stored mail should be discharged. ,
A proximity detector (not shown) detects the marker (c) of the compartment (to), and the actuator operates the opening/closing mechanism (b) of the designated compartment G based on the signal from the proximity detector. Open the bottom plate c9 and discharge and accumulate mail ←D from the designated discharge sheet (c) to the collection box (a). When mail items with the same destination information are accumulated into several pieces, the pusher unit (c) is activated to push them onto the belt conveyor (c).
The mail is conveyed from the conveyor belt (c) to the turning belt conveyor (e) to the central conveyor belt conveyor (c) to a mail dispatch center (not shown). Discharge position (C') K 7 The empty container 00 moves forward from the end of the discharge position 0 to a downwardly inclined or vertical lowering position 0, following the lowering position 00 guide rail (4) K, and from the discharge position 0 A drive mechanism using a drive roller (8) that rotates quickly or a drive chain θ→ that fixes the pin θ◆;
Alternatively, it descends from the descending position 0 by a self-propelled system using a rack and binion, and arrives at the starting end of the above-mentioned input position (2). Then, by repeating the same loading and unloading of the mail items as described above, this automatic sorting of the items to be transported can be carried out reliably and with high efficiency.

According to the present invention configured as described above, by using containers that circulate in accordance with the guide rails, it is possible to automatically sort large irregularly shaped envelopes and mail items with banding, and Sorting can be done in a short time and with high efficiency. 1. By installing the position where the transported objects are discharged higher than the position where the transported objects are sorted and input, various devices for accumulating the transported objects are provided below the discharge position. This type of sorting allows the entire conveyor device to be made compact, requiring less space for installation.
