Description

Be used for the input wheel apparatus on the flat sorter

The utility model relates to a kind of input wheel apparatus that is used on the flat sorter, exactly, relate to the input wheel apparatus in each letter sorting unit bucket that vertically is inserted into main sorter after a kind of mail of horizontal transport on the mail sorting machine piece-supply system can being turned to, belong to the mail sorting equipment technical field.

Existing flat sorter mostly is to adopt swiveling wheel or belt to transmit mail for the part part, its rotating speed is higher, be generally more than 3 meter per seconds, and it is by mechanisms grip mail to be sent into each letter sorting unit bucket, be easy to cause the mail breakage, thereby cause machine to jam or refuse branch, influence letter sorting efficient.

The purpose of this utility model provides a kind of input wheel apparatus that is used on the flat sorter, this device can reduce the speed of service of mail, makes mail lean on gravity vertically to fall into letter sorting unit bucket, can not produce jam, the mail breakage rate is low, thereby realizes sort mail accurately and rapidly.

The purpose of this utility model be achieved in that by level for the part device, drop into wheel, double-sided toothed belt and chartered steamer device and formed, wherein the level confession part device cog belt and the drive unit thereof of being cut somebody's hair by multi-ribbon formed; The chartered steamer device then is made up of cylinder and belt, is positioned at the lower right of dropping into wheel; It is characterized in that: the center of wherein dropping into wheel is the spline rotating shaft, the axial uniform discoid fork arm wheel seat of multi-disc that is set with in this rotating shaft, radially evenly be interval with a plurality of grooves on the excircle of each fork arm wheel seat, all be embedded with a fork arm in each groove and form input wheel sheet, be same radially evenly spaced a plurality of fork arms on described a plurality of inputs wheel sheets and then form the input bin that drops into wheel; And the outside of taking turns sheet in the input of this rotating shaft rear and front end is installed on the lucite disk; Between two fork arm wheel seats, be provided with cog belt belt wheel and packing ring.

Above-mentioned fork arm can be the single tine bar, also can be double fork lever.

Above-mentioned fork arm be by the rule of two single tine bars, double fork lever order radial distribution in the groove on the excircle of fork arm wheel seat, with three letter sorting shelves lattice in each letter sorting unit bucket of corresponding its below.

Fork arm number on the above-mentioned fork arm wheel seat can be 18, will drop into wheel and be separated into 18 letter sorting bins, wherein letter sorting unit bucket lattice of each corresponding its below of letter sorting bin.

Fork arm wheel seat number on the above-mentioned input wheel can be 5-7, and this axial width that drops into wheel should be identical with the width of the letter sorting unit bucket of its below.

Above-mentioned fork arm wheel seat and fork arm all are to make with aluminum alloy materials.

Characteristics of the present utility model are: this input wheel is divided into a plurality of letter sorting bins (embodiment is 18) by the aluminium alloy fork arm, connects for the tooth-shaped conveying belt of cutting somebody's hair of the multi-ribbon on the part device by many double-sided toothed belts in its rotating shaft and level, mail is sent into dropped into the bin of taking turns.Turn clockwise and drop into wheel, change mail to be sorted over to vertical input by horizontal feed, fall into its below by the letter sorting unit bucket lattice of chain traction, by letter sorting unit bucket mail is sent into the letter bag or the letter box of the predetermined bin of appropriate address again along the circular orbit operation.The input wheel external diameter size here is to design according to the size range that sorts unit bucket lattice, letter sorting unit interval and institute's sort mail.

Input wheel of the present utility model is divided into 18 bins, mail is entered respectively drop into each bin of wheel, its transporting velocity also is reduced to 0.54 meter per second from 2.1 meter per seconds, and mail is changed into vertical direction by the horizontal direction transmission to be transmitted, make mail fall into letter sorting unit bucket by self gravitation, impact for a short time, noise is low, has solved the problem of mail cracky simultaneously.

Specify structure of the present utility model and characteristics below in conjunction with drawings and Examples.

Fig. 1 is that mail is transferred to the general structure schematic diagram that sort unit bucket for the part device through dropping into wheel from level;

Fig. 2 is the lateral plan of the input wheel apparatus in the utility model.

Fig. 3 is the vertical view of the input wheel apparatus in the utility model.

Fig. 4 is the design of part schematic diagram of the fork arm wheel seat in the utility model.

Fig. 5 forms the structural representation that drops into the wheel sheet after embedding fork arm in the fork arm wheel seat of the present utility model.

Referring to Fig. 1-Fig. 3, the utility model is the input wheel apparatus on a kind of flat highspeed sorters, it is the critical component on these flat highspeed sorters, its working method is summarized as follows: after by piece-supply system the flat that the address information coding is arranged being carried out recognition coding, under motor-driven, turn clockwise by the cut somebody's hair belt wheel 3 of tooth-shaped conveying belt of band, cog belt 1 movement therewith that level is cut somebody's hair for many (being illustrated as 7) band of part device is transported to mail on many (being illustrated as 6) double-sided toothed belts 13 (referring to Fig. 3).Motor drives simultaneously and drops into wheel 12 and turn clockwise, and the belt wheel 4 of coaxial double-sided toothed belt 13 also rotates thereupon, drives double-sided toothed belt 13 rotations by this and mail flatly is transported to drop into to take turns in 12 the bin.Drop in each the input bin on the wheel 12 and can import a flat to be sorted.2 is driving pulleys of double-sided toothed belt 13 among the figure.This motor also drives input wheel 12 bottom-right chartered steamer belt feeder cylinders 10 by gear wheel reversing mechanism simultaneously and is rotated counterclockwise, and the wheel rim applying and synchronous rotation that make chartered steamer belt 9 and drop into wheel 12 can prevent that mail from flying out; Can locate by certified mail one end simultaneously, determine part position down.When the mail in dropping into wheel 12 bins forwards the upright position to, just can make mail rely on the gravity effect of self and fall into the letter sorting unit bucket 11 of its below automatically, thereby finish vertically being inserted into the task of sorting unit bucket 11 after the changed course of the mail of horizontal feed on the piece-supply system.

Again simultaneously referring to Fig. 4 and Fig. 5, the utility model drops into wheel apparatus and is made up of for part device, input wheel 12, double-sided toothed belt 13 and chartered steamer device level, wherein the level cog belt 1 and the drive unit thereof of being cut somebody's hair by multi-ribbon for the part device formed, by the chartered steamer device that cylinder 10 and belt 9 are formed, then be positioned at the lower right of dropping into wheel 12.The utility model main feature is: the center of wherein dropping into wheel 12 is spline rotating shafts 14, the axial uniform discoid fork arm wheel seat 6 of multi-disc that is set with in this rotating shaft 14, the centre of each fork arm wheel seat 6 is the splined hole that cooperates with spline rotating shaft 14, radially evenly be interval with a plurality of grooves 15 (referring to Fig. 4) on the excircle of fork arm wheel seat 6,15 li of each grooves all use bolt, rivet fixedly to be embedded with a
