Abstract

PURPOSE:To smooth the carrying by providing two co-operating pressing members at the carry path exchanging section of a belt conveyor for carrying postal matters such that each carry path can be formed linearly when the carry paths are exchanged. CONSTITUTION:Two pressing members 13, 14 are arranged at the branch of carry paths A, B, C formed by belt conveyors 1-4. With such arrangement, when exchanging the papers 9 from carry path A to B, the solenoids 15, 16 are deactivated to form the carry paths A, B linearly through said members 13, 14. When carrying to the direction C, the solenoids 15, 16 are activated simultaneously to form the carry paths A, C linearly through said members 13, 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to selectively distribute conveyed paper sheets, such as postal letters, to a first conveyance path or a second conveyance path. This invention relates to a switching device.

FIG. 1 shows an example of a conventional sheet flow switching device. In the figure, 1 to 4 are endless telescopic conveyor belts, 5 is a belt suppressor, and 6 to 8 are conveyor belts 1 to 4. The rollers rotated in the same direction as the conveyance direction of 4, and these members were arranged in the relationship shown in the figure. In this type of paper sheet flow switching device, as shown by the two-dot chain line in FIG. Due to the forced guidance, the switching angle θ is large, and among the paper sheets being conveyed by the belt, especially envelopes that are thicker than standard, and hard-to-bend contents such as ballpoint pens, metal plates, stamps, etc. are enclosed in envelopes. The postal letters packed in the inner space formed by the conveyor belts 1 to 4 damaged the postal letters and the conveyor belts.

The present invention eliminates the above drawbacks by electrically or mechanically synchronizing the belt pressing body 5 and the roller 6 and reducing the switching angle θ of the conveyance path, thereby ensuring smooth and reliable operation without damaging paper sheets or the conveyance belt. The present invention provides a paper flow switching device.

The following is a second example showing an embodiment of the present invention. This will be explained in detail in FIG. 3 as well. In FIGS. 2 and 3, the conveyor belt 1
~4. The rollers 7.8 are identical to those shown in FIG.

The paper sheet carry-in path 10 is an overlapping portion between a first conveyor belt 1 and a second conveyor belt 2 which overlaps the first conveyor belt 1 and is stretched so as to be gradually separated from each other in the running direction. The direction of conveyance is indicated by arrow A in the conveyance path of nine paper sheets. The first outlet path 11 for paper sheets and the second outlet path 12 are the first
．． A third conveyor belt stretched between the side portions of the second conveyor belts 1 and 20 in the running direction and superimposed between these portions in the running direction. The transport direction is indicated by arrows B and C in the transport path formed by the fourth transport belts 3 and 4.

1st. The second suppressors 13, 14 each have a solenoid 15.
16, an arm 17.18 connected to this solenoid, rollers 19, 20 that are rotatably supported by this arm, stoppers 21 to 24 of arm 17.18, and arm 1.
It consists of springs 25° and 26 for constantly biasing 7.18 toward the stopper 21.23. Figure 2 shows solenoid 1
5.16 is de-energized and paper sheets 9 entering from the direction of arrow A of the carry-in path 10 are conveyed in the direction of arrow B of the first carry-out path 11. Figure 3 shows a state in which the solenoids 15 and 16 are energized at the same time, and paper sheets 9 that have entered from the direction of the arrow in the carry-in path 10 are conveyed in the direction of the arrow C of the second discharge path 12, and are conveyed almost linearly. is possible.

As explained above, the present invention provides paper sheet loading paths, first and second
The unloading path and the 1st. By configuring the second suppressing body and having an action, the first suppressing body is actuated as necessary to push the first conveyor belt into the space, and at the same time, the second suppressing body is actuated and the second suppressing body is actuated. By retracting the second conveyor belt in the same direction as the pushing direction of the first conveyor belt, among the paper sheets conveyed by the belt, envelopes that are especially thicker than standard, ballpoint pens, metal plates, stamps, etc. Even if the postal letter contains hard-to-bend contents, the first delivery path is almost linear.
It can be sorted to the second unloading route. Therefore, the postal letters and the conveyor belt can be sorted smoothly and reliably without being damaged.

In the above embodiment, a solenoid was used to drive the first and second suppressors and they were electrically synchronized. The suppressor may be mechanically interlocked by a link mechanism or the like.

Having described a preferred implementation of the invention, many variations and modifications will be apparent to those skilled in the art, and it is further preferred that the invention be described without being limited to the specific examples disclosed herein. *Limited only to the range of M requirements.
