Description
~ CA 0220363~ 1997-04-24 E, Pt~
1 E,1~T I R~ lO~l Description Apparatus for separating and for transferring flat items The machine-readable post codes which should be specified on items of mail, such as letters, postcards, packets and the like, as an identification for a loca-tion, a postal district, a PO box or a major recipient permit rapid, mechanical distribution of mail. Sorting of the incoming items of mail takes place, for example, with the aid of controllable item carriers which are each loaded with an item of mail in special loading locations and then discharge said item of mail to a sorting con-t~;ner~ or a correspon~;ng sorting compartment, assigned to the respective post code. Since the sorting containers or sorting compartments may be arranged on various levels, the item carriers circulating on conveying devices must, if appropriate, also be capable of sp~nn;
various levels. After transfer of the item of mail to the assigned sorting container or the assigned sorting compartment, the empty item carriers can then once again be loaded with an item of mail when they pass a loading location. The item carriers are loaded, for example, with the aid of a rotating paddle wheel whose paddles form pockets which receive those items which have already been separated and are arriving on a conveying device a~d discharge these items to the circulating item carriers.
The separation and the transfer of the items to the conveying device which leads to the paddle wheel has to be carried out, in this arrangement, with a relatively high degree of accuracy which is adapted to the process-ing speed of the sorting apparatus as a whole.
There are also comparable sorting tasks in theso-called return of periodicals or newspapers. In this case, the publications which are not sold by the retailer are sent back to the wholesaler and are registered there and are separated out in order to be destroyed CA 0220363~ 1997-04-24 .
or are resorted in order to be sent back to the respect-ive publisher.
The automatic handling and, in particular, the separation of unpackaged periodicals or newspapers thus poses considerable difficulties both in the case of mail distribution and in the case of the return of the publi-cations. For example, in the case of the publications being handled by automatic gripping devices, -there is always the risk of the publications opening, which, in addition to the publications being damaged or destroyed, also results, in particular, in the entire sorting process being interrupted.
The invention specified in claim 1 is based on the problem of providing, with low outlay, a quickly and reliably operating apparatus which is intended for separating and for transferring flat items and should ensure, in particular, reliable handling of periodicals, newspapers, catalogs and the like.
An apparatus according to the invention may be used for the return of periodicals or newspapers, in public post offices or in central in-house mail depart-ments of large companies. Furthermore, an apparatus according to the invention may, however, also be used, for example, in storage systems or automated order-picking systems for carrying out comparable tasks inwhich flat, stackable items are to be separated and transferred to a conveying device.
The invention is based on the f; n~; ng that an endlessly circulating carry-along belt provided with one or more suction openings is highly suitable for separat-ing periodicals or newspapers, while extremely reliable guidance is provided, on the following route to the publications being discharged onto a conveying device, between the carry-along belt and an associated pressure-exerting belt. If the spine or fold of the publicationsis located CA 0220363~ 1997-04-24 at the rear, as seen in the direction of circulation of the carry-along belt, then non-secured publications are held together and it is also the case that any loose supplements which may be present cannot drop out. Separ-ation is aided by the items being in the upright state,since the item supplied in the pick-up position is drawn off upwards, while the dead weight of the next item counteracts the drawing-off force. Since the items do not have to be drawn off against an edge, it is also possible to separate items of different thicknesses.
Advantageous configurations of the invention are specified in the subclaims.
The configuration according to claim 2 permits a particularly straightforward stackwi~e supply of the items which are to be separated. Moreover, the supply of the items on a belt conveyor can be implemented with a considerably lower degree of structural outlay than the supply of the items in magazines.
The development according to claim 3 renders supply of the items easier still. Moreover, inclination of the items supplied ensures a stable position of the stack as a whole.
The configuration according to claim 4 makes possible particularly straightforward guidance of the endlessly circulating carry-along belt. With an appropri-ate selection of the diameter of the drum, the separated items are only subjected to slight curvature as they are transported further to the discharge location. According to claim 5, it is then also possible for the pressure-exerting belt to be adapted in a simple ~-nner to the curvature of the drum via three deflecting rollers.
The configuration according to claim 6 means that it is possible, by way of the deflectors which can be switched on and off, for the item supplied in the pick-up position to be carried along in a specific manner at the respectively desired point in time.
~ CA 0220363~ 1997-04-24 t ~ . .
The development according to claim 7 makes it possible for the entire apparatus for separating and for transferring items to be coordinated with a division of the item-receiving conveying device. If, for example, two or three apparatuses are used, it is only every second or third division of the conveying device which is served by ~ any one apparatus. Moreover, the apparatus may also be coordinated with a non-uniform division of a conveying device.
10According to claim 8, it is also possible for two or more separation and transfer operations to be carried out per revolution of the drum.
The configuration according to claim 9 permits, by straightforward means, full compensation of any slippage which may occur when the item is grasped.
According to claim 9, the speed of the-carry-along belt is controlled in a simple manner via the rotational speed of the driving drum.
An exemplary embodiment of the invention is described in more detail hereinbelow and is illustrated in the drawing, in which:
Figure 1 shows a side view of an apparatus for separat-ing and for transferring periodicals and news-papers, and Figure 2 shows a plan view of the apparatus according to Figure 1.
Figures 1 and 2 respectively show a side view and a plan view of a vastly simplified schematic illustration of an apparatus for separating and for transferring items S to a conveying device designated by F. A device designated by E is provided for receiving the items S, which are here in the form of periodicals and newspaper~
of different formats and different weights, and for supplying these items -- CA 0220363~ 1997-04-24 .~ - 5 -S in a front pick-up position A. This device E is a horizontally aligned belt conveyor which can be driven in a stepwise manner in the direction of the pick-up position A and on which the items S are positioned by hand in stacks in an upright, slightly forwardly inclined state. The conveyor belt of the belt co~eyor (not - illustrated in Figure 2) is formed by a plurality of belts which are spaced apart from one another in.
parallel.
10Provided for the purpose of grasping the item S
supplied in the pick-up position A is a carry-along belt NB which circulates endlessly above the conveying device F, around a roller RO and a drum T, and in whose three mutually parallel sections five suction openings SO are provided in each case. The five suction openings SO of one belt section can be connected in -each case, via a suction chamber SK arranged on the rear side of the belt, to a vacuum source (not illustrated in any more detail in the drawing). The item S supplied in the pick-up position A is thus grasped by the carry-along belt MB, by way of the suction action of the suction openings SO, and is drawn off upwards, slightly obliquely, from the r~m~;n;ng stack tangentially to the drum T. Immediately following this separating ~,o~e~,ent, the item S is then drawn into the opening gap between the carry-along belt MB and a pressure-exerting belt, which is designated by AB. This endlessly circulating pressure-exerting belt AB is guided over three deflecting rollers UR such that it wraps around the drum T in the desired guidance region as far as the discharge location. The direction of circulation of the pressure-exerting belt AB (not illustrated in Figure 2) is depicted in Figure 1 by an arrow PF. In this arrangement, the pressure-exerting belt AB can be driven or else can also be carried along in a frictionally locking m~nnet- by the carry-along belt MB circulating at the speed v.
The periodicals or newspapers which, as the items S, are positioned on the conveyor belt of the device E
with the spine or fold to the bottom and inclined .
~ CA 0220363~ 1997-04-24 .. .
: - 6 -slightly forwards towards the carry-along belt MB and the drum T can be prevented from m~k; ng contact with the carry-along belt MB by two spaced-apart deflectors AW. If the item S supplied in the pick-up position A is then to gra~ped via the suction-openings A0 ~sic], then the two deflectors AW arranged in the region of gap~ L between the section~ of the carry-along belt MB are drawn back into associated channel-like depressions V of the drum T.
The deflectors AW, which are fastened on the shaft WE, are moved in and out by correspo~; ng rotations of the shaft WE.
The pressure-exerting belt AB (only illustrated in Figure 1) is subdivided into a plurality of mutually parallel belts. In this manner, an optical sensor SS can be arranged in the region between the three deflecting rollers UR, said sensor detecting, at this location between two belts, the beg; nn; ng and/or end of the item S which has been carried along by the carry-along belt MB
in each case. It can be seen from Figure 2 that the signal SI of the sensor SS is fed to a control device SE.
This control device SE, for its part, acts, via an output signal AS, on a drive motor AM, which drives the drum T
via a drive belt RT and the drum shaft, which is desig-nated by TW. The mounting of the drum shaft TW is indi-cated in Figure 2 by ball bearings KL.
The sensor SS thus detects the position in whichthe item S grasped by the suction openings S0 is located on the drum T. Any slippage which may be determined by the sensor SS when the item S is grasped and carried along can thus be compensated, via the control device SE, by the rotational speed n of the drum T, and thus the speed v of the carry-along belt MB, being changed corre-5po~ ; n ~ly .
In the exemplary embodiment illustrated, the conveying device F which receives the separated items Sis a belt conveyor whose conveyor belt (not shown in any more detail) CA 0220363~ 1997-04-24 moves at the speed u in the transporting direction. On the conveyor belt, transverse ribs QR create a division ~ for receiving the items S and transporting them fur-ther. The speed u of the conveying device F and the rotational speed n of the drum T and the speed v of.the carry-along belt MB are coordinated with one another such that transfer of the items S to the conveying device F
takes place with each division t, or i~ each case a whole-numbered multiple of the division t, of the conveying device F. By changing the rotational speed n of the drum T and the speed v of the carry-along belt MB, transfer of the items S may, if appropriate, also be coordinated with a non-uniform division of the conveying device F.
The abovedescribed apparatus for separating and for transferring items S leads to a rotating paddle wheel whose pockets, formed by the individual paddles, receive the items S arriving on the conveying device F and, following corresponding rotation on item carriers circu-lating therebeneath, discharge said items to a sorting apparatus.
Details of a suitable paddle wheel can be gathered, for example, from Patent Application P 43 44 437.8. Details of a suitable sorting apparatus are explained, for example, in Patent Applications P 43 23 564.6 and P 43 23 565.4.
