Description

BRIEF DESCRIPTION OF THE DRAWING

(1) In the drawing:

(2) FIG. 1 shows a longitudinal section through a separating station along the processing line of the apparatus for franking flat items of mail, and

(3) FIG. 2 shows a plan view of the apparatus illustrated in FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

(4) FIG. 1 illustrates an apparatus 1 for processing flat items of mail 4 supplied individually or removed at the underside 3 of a supplied stack 2 (as illustrated) from a feeder 5 for franking purposes, such as envelopes, mailers, cards, printed products or journals and catalogues, sleeves for inlaid/inserted products or the like. To this end, the apparatus 1 comprises a separating station 7 formed from a feeder 5 and separating device 6, in which the items of mail 4 arriving are processed individually and are transported onward on a processing line 8 connecting the separating station 7 and a franking station in a conveying manner. In the transport region 9 between feeder 5 and the separating device 6 assigned to the latter, the processing line 8 has at least two transport rollers 11, 12 which form a horizontal transport plane 10 for the separated items of mail 4 and, lying transversely beside one another and at intervals in the transport direction F, preferably have the same diameter and the same peripheral speed and are driven in the same direction. The transport rollers 11, 12 are mounted in a motor-driven manner at their ends in a housing or frame 13 of the apparatus 1 or a franking machine.

(5) The apparatus 1 is followed in the transport direction F by a franking unit connected downstream (not illustrated) for printing, franking or imaging the items of mail 4, which is connected to the present apparatus 1 synchronously and in a conveying manner by the driven transport plane 10 or the transport rollers 11, 12.

(6) FIG. 1 shows the apparatus 1 with items of mail 4 which have been introduced, forming a stack 2 in the feeder 5 and are conspicuous because of different thickness dimensions and format sizes. Of course, by using the apparatus 1 illustrated, identical-format items of mail 4 can also be processed and separated. The items of mail 4 supplied in a stack 2 in feeder 5 are gripped at the transport roller 12 under the action of a positioning member 15 of the separating device 6, and the items of mail 4 overlying/lying above the lowest item of mail 4 are held back and multiple withdrawals from the feeder 5 are prevented. As soon as the lowest item of mail 4 from the stack 2 has been gripped by the transport slier 12 and the positioning member 15, it is transported onward in the transport direction F by the transport rollers 11, 12 in the transport plane 10 and is guided between the pair of conveyor rollers 16 connected downstream of the transport plane 10, of which at least one conveyor miler 17 is driven, whereas an upper, preferably resiliently supported conveyor roller 18 can be driven via a frictional connection with the conveyor roller 17 corresponding to the transport rollers 11, 12 and forming a conveying gap.

(7) In order that the items of mail 4 reach the separating device 6 with the edge 19 leading in the transport direction F in each case aligned in an accurate position and uniformly, the feeder 5 has a front guide/feeder wall 20 inclined preferably counter to the onward movement F, the lower end of which forms with the transport plane 10 a passage/removal opening 21 for the items of mail 4 to be separated. The guide/feeder wall 20 is preferably inclined rearward and extends at least partly over the width of the transport plane 10; it can be adjusted/set in order to change the height of the passage opening.

(8) To adjust the passage opening 21 or the guide/feeder wall 20, lateral guides (not visible) are provided, on which the guide wall 20 is vertically displaceable. The lower end of the guide wall 20 is designed to be angled in the transport direction F, in order as a result to be able to ensure a trouble-free passage of the items of mail 4 at the passage opening 21. For the optimal support or contact of the items of mail 4 in the transport plane 10, the first transport roller 11 is a freely rotatable support roller 22 lengthening the transport plane 10 underneath the items of mail 4 stacked in the feeder 5, mounted in the housing/frame 13 of the apparatus 1.

(9) Furthermore, according to FIG. 1, at the rear end of the feeder 5 in the transport direction F there is arranged a freely rotatable or independently driven support roller 23 supporting the items of mail 4 in the transport direction F at the rear end above the transport plane 10, via the frictional peripheral surface of which the feeding of the items of mail 4 for the separation is assisted. This support roller 23 can be replaced by one with a larger diameter and its position, matched to the transport length of the items of mail 4, can be adjusted/set in the transport direction F in the housing 13 of the apparatus 1, so that the rear ends of the items of mail 4 stacked in the feeder 5, as viewed in the transport direction F, are supported so as to be raised above the transport plane 10 on the periphery of the support roller 23, after the plane 26 of the latter running at right angles through the axis.

(10) An actuating member 24 that can be pivoted about a crosswise axis is mounted before the first transport roller 11 in the transport direction F in the housing/frame 13 of the apparatus 1. This mechanical actuating element 24, illustrated in the operating position of the apparatus 1 and by a broken line in the non-operational position, starts the operation of the apparatus 1 or the franking machine as soon as an item of mail 4 comes to lie on the actuating element 24 or an item of mail 4 rests on a support roller/s 22 and the transport rollers 11 and 12 and in the transport plane 10. The operation of the apparatus 1 is triggered by means of a light barrier 25, which is assigned to the actuating element 24.
