Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alignment device for aligning envelopes and postcards (hereinafter referred to as mail items), which are transported in various states in an automatic mail processing machine, to the surface of a transport board. .

Automatic mail processing machines detect stamps, postage stamps and postal codes, and apply postmarks to stamps or postage stamps. It is necessary to convey the mail items along the surface of the conveyance board.

Many pieces of mail are short, bent, or not completely glued, and these items are mixed with normal mail when they are processed. The device allows these mail items that have been conveyed along the board surface to pass through as is, while those that have been conveyed in a floating or tilted state from the board surface are sent along the board surface. put out. However, with conventional alignment devices, there are various drawbacks such as belt dislocation, damage to mail, and jamming due to items that are short, bent, or not completely glued. Although many attempts have been made, a perfect alignment device has not been achieved. An example of a conventional alignment device will be described below.

The conventional apparatus shown in FIG. 1 and FIG.
Inclined endless belts Ia and Ib, which are hung around c and 2d and rotated in the directions of arrows 5a and 5b, respectively, and rollers 4
The belt 3 is provided with an endless belt 3 which is hooked around the belts a and 4b and rotated in the direction of the arrow 6.

Mail is sent in from the direction of arrow T, and when it passes through the gap between the inclined endless belts la and lb, it is pressed against the endless belt 3 side and aligned. However, since the height at the entrance is high for mail items 8 that are not completely glued, bent mail items 9, and mail items 10 that are low in height, the inclined endless belt I
The mail is not completely caught between the rollers 2b and 2d of the alignment device, and is fed in in a state where it protrudes from the conveyance surface and gets caught up in the rollers 2b and 2d at the exit of the alignment device, causing problems such as belt slippage, damage to the mail, and clogging.

When a literate level of alignment is required, use rollers 2a, 2b, 2c.
, 2d increases, the inclined endless belts Ia, 1b
Since the entrance side of the mailbox is located higher, it has the disadvantage that mail is more likely to get caught in the mail. In addition, in order to obtain a large alignment amount with a small roller inclination, alignment devices must be arranged in two stages and three stages in series, resulting in the disadvantage that the entire device becomes large. The present invention aims to eliminate the above-mentioned problems under the current situation, and will be described below with reference to FIGS. 3 and 4, which are one embodiment of the present invention.

This device has a plurality of alignment rollers 11a, 11b facing each other, tilted in the conveying direction with respect to the substrate surface, and driven to rotate in the directions of arrows 12a and 12b, respectively.
g, 11h, two guide plates 13a, 13b arranged to face the conveying surface, and an endless belt 16, which is hung around rollers 14a, 14b and rotated in the direction of arrow 15.
Only one side of the alignment rollers 11c, 1
1e, 11g and a substrate 17 on which the guide plate 13a is supported;
The substrate is supported by arms 18a and 18b, and shaft 19a
, 19b in the direction of the arrow 20, and the alignment rollers 11a, 11b...1.
A spring 21 for balancing the pressing pressure between the rollers 1g and 11h with an appropriate force, and the alignment rollers 11a and 11b.
. . . Consists of a stopper 22 for controlling the distance between the rollers 11g and 11h.

Next, the operation will be explained.

Mail is sent from the direction of arrow 23. In Fig. 4, mail 2 has been conveyed along the board surface from the beginning.
4a is conveyed as it is, mail 24b is conveyed in a raised position, and mail 524c is conveyed tilted by alignment rollers 11a, 11b, which are arranged at an angle.
... While passing between rollers 11g and 11h, it is pressed against the endless belt 16 side and aligned. In addition, if mail is transported that is thicker than the distance between the alignment rollers 11a, 11b, . . . 11g, 11h, the link mechanism adjusts the distance between the rollers according to the thickness of the mail. The mail is pushed out, and the mail is neatly arranged and sent out.
According to the present invention, as with a belt-based alignment device, mail items of low height, bent mail items, mail items that are not completely glued, etc. protrude from the conveying surface and are not caught in the belt. Since there is no place to do so, there will be no problems such as mail clogging or belt slipping.

In addition, in order to increase the amount of alignment, alignment rollers 11a, 11b,
... Even if the inclinations of 11g and 11h are increased, the mail can be conveyed under the same conditions from the entrance to the exit of the alignment device, so even low-height mail can be smoothly aligned, and the belt can be easily aligned. Since there is no need to arrange two or three stages in series like in the alignment device used, a large amount of alignment can be obtained over a short distance, which has the advantage that the entire device can be made smaller. Although the above example describes an example in which the alignment rollers are opposed to each other, it is clear that similar results can be obtained even if they are arranged in a staggered manner.

In addition, for thick mail, the distance between the rollers is expanded by a link mechanism, but the thickness of the mail is detected in advance in front of this alignment device, and the signal is used to control the motor or solenoid. The distance between the rollers may be forcibly adjusted by a driving device. Also, the material of the roller may be made of rubber or sponge-like material with elasticity or compression properties to avoid changes in the thickness of mail items. , cards, stock certificates, etc., there is no need for a link mechanism. As described above, the present invention is capable of handling paper sheets of various shapes and sizes without causing problems such as belt slippage or clogging, and even with a large amount of alignment, the paper sheets can be reliably aligned within a short distance. Moreover, this method has an extremely excellent effect in reducing the size of the device.
