[0004] The operation in one of the sorting boxes during operation includes a lower belt 45, an upper belt 49, and a sorting blade 4.
There is no particular problem in dropping the mail into the sorting box according to (6). Since this operation is exactly the same in the present invention, it will be described later in detail in an embodiment of the present invention.

[0005] The problem is that the automatic mail sorting apparatus is integrated with all the sorting boxes, so that some of the sorting boxes cannot be removed.

[0006]

In the above-mentioned conventional automatic mail sorting apparatus, since the entire apparatus is configured as an integrated apparatus, when the apparatus is defective, the entire apparatus must be stopped for a long time to repair the apparatus. And the maintenance work often needs to be performed from the back of the device, so that the device cannot be installed in close contact with the wall, and a considerable space for work needs to be provided on the back. was there.

[0007] An object of the present invention is to make each of the sorting boxes detachable individually as in claim 1 or in a plurality of units as in claim 2, so that one whole is provided as in the conventional method. Instead of using the rear panel for each section box, or using multiple rear panels for each section box, and correspondingly dividing and arranging the upper conveyor belt, the equipment can be partially used for maintenance and inspection or repair work. The present invention provides an automatic mail sorting apparatus that can shorten the operation stoppage time because it can be replaced with a good product, and furthermore, because it is not necessary to place a space behind it, it can be efficiently used in a place by attaching it to a structure. That is.

[0008]

According to a first aspect of the present invention, there is provided an automatic mail sorting apparatus, wherein a rear plate of the sorting box is divided for each sorting box, and the upper conveyor belt is also moved in the traveling direction. And the belt is arranged so that the cut of the belt does not overlap with the cut of the lower conveyor belt.

In the automatic mail sorting apparatus according to a second aspect of the present invention, the back plate of the sorting box is vertically divided into each of the sorting boxes, and is integrated into predetermined plural pieces in the horizontal direction, and The upper conveyor belt has a continuous length in the traveling direction for each of a plurality of integrated back plates, and the cuts are arranged so as not to overlap the cuts of the lower conveyor belt. .

[0010]

In the mail sorting apparatus of the present invention, the handling of mail in each sorting box is no different from the conventional method.

In the prior art, when stopping for repair and inspection, some of the sorting boxes could not be removed, and a total stop for a long time was required. For each box, or as a unit with a plurality of predetermined sorting boxes
Since the structure is replaceable, the stop time may be short. In other words, remove the screws on the back plate of the section box in that part,
Pull out the compartment box forward. Immediately, attach the prepared good sorting box there. Therefore, the operation can be started in a short time. The time required for the service is irrelevant for operation.

As described above, since the repairing work of the sorting box is performed by pulling out the portion forward for each small unit, the rear portion of the entire apparatus can be attached to the wall, and the use efficiency of the place can be improved.

[0013]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1A shows an embodiment of an automatic mail sorting apparatus according to the present invention, in which one sorting box is divided for each sorting box, and shows a state in which mail is not being received. 1 (b) is a plan view of FIG. 1 (a) with a partial top surface removed, FIG. 2 is a front view of FIG. 1 (a) showing mail being received, and FIG. It is a front view showing typically the case where the section box of an example is arranged by m steps xn pieces.

As shown in FIGS. 1 (a) and 1 (b), one sorting box 1 is composed of a collecting box 2 for collecting mails, and a motor 3
, Two lower belts 5 on these rollers 4, a driven roller 4 ',
Between the lower belt of the immediately preceding partition box, one partition blade 6 provided at a break between the lower belt 5 and the solenoid 7 that lifts the partition blade 6 by timing control, and between two lower belts that run in parallel And two upper belts 9 and four driven rollers 10 and 10 ′ for pressing mail on the lower belt 5. Inside the stacking box 2, there is a horizontal receiving plate 12 having the same size as the box 2 which moves up and down. The supporting piece 13 and the spring 13 are moved up and down in accordance with the weight of the mails stacked on the receiving plate 12. (Not shown) is attached to the back plate 11. A J-shaped accumulation holder 14 is provided below the guide 8 from below. The back plate 11 is attached to a structure behind by four screws 15.

Next, the operation of this embodiment will be described.
The roller 4 drives the lower belt 5 and drives the upper belt 9 by frictional force. The postal matter 16 is conveyed in the direction of the arrow A between the belts 5 and 9, and is moved to the solenoid 7 of the designated sorting box.
Are collected on the receiving plate 12 by the divided blades 6 that have been flipped up.

When repairing or inspecting one sorting box 1, the entire belts 5, 9 are stopped. Next, screw 1 of the box
Remove 5 and pull it out to the near side. Immediately, attach the prepared good sorting box. Thus, the operation can be restarted with a short stop. Inspection and repair of the removed parts shall be performed independently of operation.
