Abstract

A separating station is provided with a feed deck (22) for supplying flat goods to a good processing station following in the transport direction in the transport direction x of a Cartesian coordinate system, with openings in the feed deck (22) for at least one first roll (23a) in a singling area and with separating means and with a pressure box (26) equipped. The pressure box (26) is movably mounted in the z-direction of the Cartesian coordinate system and has a rocker (264) which is pivotally mounted at a downstream end. At another upstream end of the rocker (264) pivotally mounted in the pressure box (26), one end of a singulation means carrier (267) is mounted in an L-shape such that a stop side (2671) of the undeflected singulation means carrier (267) is parallel to the y-axis. z-plane and extends against a y-direction of the Cartesian coordinate system. The separating medium carrier (267) can be deflected in a distance which is variable in accordance with the thickness of the flat material to be separated over the feed deck (22) and can be adjusted by means of adjusting means in the y direction and in the opposite direction.

Description

The invention relates to a separating station according to the preamble of patent claim 1. Such a separating station is used in a good processing system, for example as a station of a postal road of a franking system.

The mailing line of a franking system conventionally consists of a plurality of individual juxtaposed mailpiece processing stations. A docking station is upstream of the singulation station, i. often placed at the beginning of the post road and serves to create individual or stacked mail items to the separating station, which separates the stack. If a stack of mail items with different formats (mixed mail) has been created to a separating station, high requirements must be satisfied for separating. The individual mail items are fed directly or via a dynamic scale to a franking machine and then deposited in a storage station.

In America, the standard "letter" formats are required, such as Letter 8 1/2 "x 11" (21.59cm x 27.94cm), Letter 8 1/2 "x 14" (21.59cm x 35 ") , 56 cm), Letter 14 7/8 inch x 11,69 inch (37,8 cm x 29,69 cm).

In Germany in particular, the sizes are B4 (25.0 cm x 35.3 cm), B5 (17.6 cm x 25.0 cm), B6 (12.5 cm x 17.6 cm) and C4 (22.9 cm) cm x 32.4 cm), C5 (16.2 cm x 22.9 cm), C6 (11.4 cm x 16.2 cm) common. The sizes of the German paper formats have already been specified in the year 1922 by the German Institute for Standardization (DIN) in the DIN standard DIN 476.

When referring to a stack below, it is meant to include a stack of letters, a stack of postcards, and other mailpiece stacks which can be singulated, but other stacked flat items should not be excluded.

There are already means for transporting the mail items both downstream, as well as in the direction of the alignment wall and for loosening the mailpieces (open or closed filled envelopes) of a stack known, so they can easily slide over each other. In addition, multiple skewing of the post-stacking plate in the stacking hopper area has been proposed in order to utilize gravity for the alignment of the mailpieces. Due to the multiple skewing of the post-stacking plate in the stacking magazine area, the envelope may optionally pinch when passing into the feed area with horizontal, in particular when the flap is open. Due to the small angle range, an alignment of the mail pieces is possible only to a limited extent.

According to the EP 1 533 260 B1 a vibrator device for the delivery of mailpieces (letters) is proposed to a separating station. On the entire width of the lock of the aforementioned separation station, an outer strip is arranged with a movable slide, at the end of a Einrüttelklappe is arranged. After applying a stack with letters lying on the page, the letters are pushed by means of the Einrüttelklappe in the longitudinal direction against a Ausrichtwand and thereby loosened by means of Einrüttelklappe and thus aligned, ie brought into the correct position before a subsequent dicing and printing. The Einrüttelklappe forms a laterally displaceable stop with a sliding guide, which must be set to the letter width and can be locked in this position by means of a friction brake. The Einrüttelklappe acts directly on the lateral positioning of mailpieces. In addition, a second sliding guide is provided which allows a resilient overstroke by means of a spring, so as not to pinch the letters. However, hereby only letters of the same format can be aligned.

A feeding device according to the EP 1 958 902 B1 , Is equipped with an improved transport device having a plurality of driving means, the peculiarity is that it consists of a cylindrical wheel with gearwheel-like teeth on its circumference, between which axes for small non-driven independently rotatable rollers are arranged. Alignment is possible by manually pushing a mailpiece or stack of mail pieces to an alignment wall.

The EP 1 510 480 B1 B1 relates to an alignment device of a mail processing system having shaking and aligning means with a number of retractable elements projecting through openings of a horizontal plate, the distance from an alignment wall (reference wall) of the format of the mail pieces is adjustable to forcibly push the mail pieces, which should help to prevent skewing of the mail pieces.

In the above-mentioned European patents EP 1 533 260 B1 . EP 1 958 902 B1 and EP 1 510 480 B1 The functions of the landing station and separating station were combined in a single feeding and printing station. The correct alignment of the mail pieces is realized by various sliding elements and Einrüttelelemente.

These good processing devices are very loud in operation and also susceptible to interference when processing a stack of mailpieces. While the alignment of individual mail pieces is straightforward, problems can already arise in aligning a stack of uniform mail pieces if mail pieces have format deviations. Major problems arise when aligning a mixed mail stack containing differently sized nonuniform mail pieces.

In the field of franking machines, it is already known to transport a piece of mail separated from a stack in the transport direction downstream and to print it with a franking imprint during transport. In the franking machine Centormail® Applicant already mixed mail is transported standing on the edge by means of a conveyor belt, wherein at the edge automatically aligning the mailpieces by gravity. To the franking machine Centormail belongs a reworked in 2009 automatic feeding station. In the separation area sliding levers are adjacent, which have a different length and are mounted on a separating shaft and coupled to a return means. It is advantageous that the letters can be up to 20 mm thick and yet an optimal withdrawal behavior from a stack of mailpieces through the automatic feed station is possible.

In the field of franking machines, solutions are also known which transport a postal item lying on one side in the transport direction downstream, such as, for example, the PostBase® postage meter machine of the applicant. This franking machine can be preceded by an automatic feed station on the input side. For flat on one side downstream transported flat goods is a feeder station from the German utility model DE 20 2012 011 877 U1 known, which has a pressure box with two pressure rollers, which cooperate with two rotatably mounted in a frame transport rollers to further transport a flat Good downstream. The pressure box carries a rocker in its downstream part, which is rotatably mounted with its one end about a Drehachswelle and at the other gutstromaufwärtigen end carries a run-up plate, are attached to which singulation fingers, which cooperate with a second separating roller. Disadvantageously, the separating gap is displaced in the transport direction x, the farther the lock opens. A pre-separation plate is mounted on the frame opposite the feed deck and forms therewith an invariable gap of a pre-sluice. Since the gap can not be enlarged, it is difficult to remove a jam at the pre-separation plate. The franking system thus formed is also suitable only for uniform mail items.

From the European patent EP 2 325 120 B1 For example, a device for selecting postal articles with multiple rotatable fingers is known. At least two adjacent independently pivotable selectors have fingers of different lengths, each of the selector fingers being pivotable about a common pivot axis and against a respectively associated resilient return means. This advantageously makes it possible to avoid double feeds of mailpieces (envelopes).

From the European patent EP 2 325 808 B1 is a separating device is known, which is equipped in the upper part of a lock with a number involute curved selection lever, which cooperate with a selection role in the lower part of the lock. Several selection levers are arranged side by side on a rod whose axis forms the axis of rotation of the selection lever. The circle involute of each selection lever has a vertical section. Each selector lever is separately returned by spring force with at least one of the selection levers contacting the mailpiece in an area extending from the centerline of the mailpiece parallel to an alignment wall to a side of the mail piece furthest from the alignment wall. A first selection lever is at a first distance of 60-85 mm, a second selection lever is at a second distance of 120-150 mm and a third selection lever is positioned at a third distance of 180-230 mm from the alignment wall. The selection levers can only be moved independently of each other. In a B4 DIN format, the mailpieces are 25 cm wide and 35.3 cm long. A format deviation can cause malfunctions. A mere 2/3 wide mail piece would be 16.67 cm wide and would thus be smaller in width than the DIN format B5 (17.6 cm x 25 cm). The above mentioned minimum distance 180 mm for the third selection lever would still be too large and would cause the 2/3 DIN format B4 wide mail piece can not be pressed by the third selection lever to the selection role in the lower part of the lock. With a format deviation of plus 2 cm from the largest standard US Letter size 8 1/2 inch x 11 inch (21.59 cm x 27.94 cm), a third selection lever at a third distance of 230 mm from the alignment wall would just barely be effective and press the mail piece of the DIN format B4 to the selection role in the lower part of the lock. With a smaller positive deviation from the US format, interference may result, for example, if the edge of a 22 cm wide format does not reach the third selection lever and pushes up against a spring force or even lies next to it and causes unwanted friction.

With a stack of at least two mailpieces having a format deviation and / or a misaligned skewed stack, the overlying mail pieces might overhang, particularly if the lowermost mailpiece is thicker and smaller in format, e.g., the lowermost mailpiece has the DIN B5 format and the upper mail piece the DIN format B4. For example, the second selection lever would press the top and bottom mail pieces of the DIN format B5 and the third selection lever would only press the top mail piece of DIN format B4 onto the selection rollers, which would pull the two mail pieces into the gap of the lock simultaneously.

In the mail items occur in practice and format deviations, which can lead to undesirable disruptions of the operation. To be on the safe side, a stack of mail pieces is then aligned by hand on one edge of the stack and only then manually applied to the separating station.

By mixed mail are to be understood below different thickness flat mostly uniform mail pieces of a stack, which must be processed despite the tolerance of up to +/- 20mm the dimensions of the mail processing stations.

It is an object to develop a separation station for both a single flat good as well as a stack of flat goods and its supply of isolated goods to a subsequent station. The separation station is intended to allow a high throughput of flat goods, which are transported lying on the side, without the above-mentioned disadvantages of the prior art occur.

In addition, a jam of larger standard formats should be easy to fix. The flat goods within a stack should have different dimensions (Thickness up to 10 mm and format deviations) may have. The separating station should be suitable for mail items but also for another stackable good, which has in format stacked format deviations up to 20 mm in length and width. The flat material should lie with the long side against a good upstream alignment wall and aligned in the separation station be retracted before it is isolated to the subsequent stations handed over.

The object is achieved with the features of a separating station according to claim 1.

The separating station has a first lock area with a first roller of a separating area in the lock lower part. At least one separating roller is formed on the first roller of the separating region. Each separating roller consists of a roller body, which is covered with a tire. There are a plurality of singulation rollers with tires of rubber or plastic or of another material with a high coefficient of friction, which project through an associated opening in a feed deck of the singulator station in a z-direction of a Cartesian coordinate system, wherein the z-direction of the direction of gravity opposite. It is contemplated that a pivotally mounted rocker is extended at its other upstream end and that one end of a singulator carrier is mounted at the rocker end so that one stop side of the undeflected singulator carrier is aligned parallel to the y / z plane of the Cartesian coordinate system extends opposite to the y-direction. In a gutstromeingangsseitigen plan view of the y- / x-plane of the Cartesian coordinate system opens up an L-shaped arrangement of rocker and Vereinzelungsmittelträger in the lock shell.

A number of separating fingers are provided on the separating agent carrier opposite the first roller of the separating region. The singulation fingers are assigned in pairs to each side of the frosted separating rollers. Both elements work together in such a way that each of the lower Good is separated from the stack and transported downstream. The Vereinzungsungsmittelträger has a torsion-resistant profile and has a well upstream arranged vertical stop wall against which a stack of flat goods strikes and a stop plate, which has an oblique insertion area in the Sluice forms, wherein the separating fingers are mounted on the inclined stop plate of the separating agent carrier.

The separating agent carrier is attached to the rocker, which is rotatably mounted at its one downstream end located at one end. When separating, the separating medium carrier with the separating fingers lifts against gravity according to the height of the goods from the separating rollers, wherein the separating agent carrier is raised in a thickness that can be varied according to the thickness of the flat space above a feed deck. The distance between the lock and the pivot point is increased so far with an extension arm of the rocker that the separation gap in the transport direction x shifts only insignificantly when separating flat goods to 10 mm when the lock opens. Advantageously, an L-shaped arrangement of rocker and Vereinzungsungsmittelträger a jam of larger standard formats easily fix by manually grabbing the good behind a boom and pulled out of the separating gap, including a reduced width of the feed deck downstream to the boom of the separating station provided is. The boom covers the Vereinzelungsmittelträger from above U-shaped.

A second lock area lies opposite to the y-direction next to the first lock area and has at least one separate separating roller in the lock base. This at least one separate separating roller is arranged transversely to the transport direction x and in a line to the first lock area with a distance c away from a vertical alignment wall of the separating station. The distance c corresponds to about 2/3 to 4/5, preferably 3/4 of a width of a flat Guts the largest format with a format deviation of +/- 20 mm. The at least one separate separating roller is positively and / or non-positively connected to the first roller of the separating region. The first roller of the singulation area in the first lock area and at least one separate singulation roller in the second lock area are preferably driven by a common rotary axle. In the upper lock part, a rigid mechanical connection between the first and second lock areas is produced by the separating agent support. In the area between the two lock areas, a gap is formed in the separating means. It is envisaged that a flat good to be separated with a corresponding format width due to a traction passes through both lock areas simultaneously. The separating means of the The second lock area move as the separating means of the first lock area are moved in the z-direction. It has been empirically determined that thus advantageously the risk can be reduced that another flat good (mail piece) is pressed against the at least first separating roller, which can lead to the double or multiple feeding of mail pieces in the gap of the lock. Alternatively, a wide single lock with a gap in the separating means can be provided. By a wide lock with two lock areas or two rigidly coupled locks (separating means against a number of separating rollers on a rotary axle) a stack is kept stable when removing the lowest flat Guts in a peeling position, causing a tilting of subsequent further flat goods (mailpieces ) prevented during the removal of the lowest flat good (mail piece) of a stack. Also, this advantage is achieved without the use of vibrating elements and / or other means.

In one embodiment, not only the extension of the rocker is achieved by means of an extension arm, but also the arrangement of adjustment means is easily possible. The extension arm, for example, consists for example of a box-shaped bent sheet metal part, with two side legs and a yoke, are mounted on the two spacer dome of a holding plate. In a space between the extension arm and the two spacer domes a support plate is arranged to the swing guide, which is associated with a Justagemittel.

For example, a precise guidance of the rocker in the z-direction is achieved by means of a guide track, which is formed on the holding plate of the separating medium carrier, and with two ball bearings, which are each arranged on a bolt on the carrier plate for the swing guide. The support plate for swing guide is slidably mounted in the y-direction on a fixed axis and allows by means of an adjusting nut the exact setting of the separating finger to the at least one separation roller (roller body) of the first roller of the separation area in the first lock area and the at least one separate separation roller (roller body) in the second lock area. Two bilateral bends of the support plate to the swing guide point in the transport direction x and have openings for a fixed axis, which is mounted on a support plate angle. At least two Andruckfinger are rotatably mounted side by side on the axis, wherein the Pressure fingers are preferably formed the same length. The second roller in the separation area and the pressure fingers act together to hold down the flat goods and to transport them further.

An adjustment means is supported on the fixed axle and permits the overlapping of the separating fingers to the at least one separating roller of the first roller in the separating region and at least one separate separating roller. Two fastening elements of the separating agent carrier are anchored in the holding plate in order to set a parallel alignment of a short edge of all singulation fingers to the feed deck.

The separating agent carrier is mounted on the gutstromeingangsseitigen surface of the mechanical support plate. The separating medium carrier has a run-on plate, which is angled downwards in the direction of gravity and in the transporting direction x at an oblique angle downwards from a stop side of the run-up plate lying parallel to the y / z plane. The separating means, which cooperate with the at least one separating roller of a first roller of the separating area in the first lock area and with a separate separating roller in the second lock area, in order to open the lock in accordance with the thickness of the respective lowermost mail item, are fastened to the starting plate. In the transport direction x, a first and a second roller in the transport area follow the first and a second roller in the separation area. All rollers are rotatably mounted below a feed deck in a frame and provided with an integrated freewheel mechanism. A frame rear wall extends in the z-direction behind the back of a vertical alignment wall for flat goods. The carrier plate angle is attached to the frame rear wall and angled in the y direction. The separating medium carrier mounted on the holding plate is arranged with its mounting position close to the vertical alignment wall of the separating station and has a width which corresponds to the width of the largest possible format of the flat goods and is angled in its opposite direction to the y-direction in the transport direction x. The at least one separating roller of the first roller of the separating region has a distance a from a vertical Ausrichtwand and lies exactly in the middle of the first lock area, wherein the smallest format determines the width of the first lock area and thus the distance a, in which a flat Good with a smallest possible format is still isolated. Further separating rollers can be arranged symmetrically on both sides of the at least one separating roller then the tread of a pad, which is mounted on each roller carrier, be kept narrow. The covering may be formed as a rubber tire or consists of another artificial material with a high coefficient of friction.

By the preferred embodiment, but an alternative embodiment is not excluded, in which the at least one separating roller has the width of the first lock area.

It is provided that at least one first separating roller of the first roller is offset from the separating means in the y-direction in order to form a first lock area, that a further separate separating roller is offset from a separating means in the y-direction by a second lock area form that the further separate separating roller of the second lock area in the lock bottom is arranged transversely to the transport direction and parallel to the first lock area at such a distance c (farthest) from a vertical alignment wall of the separating station, so that a gap in the separating means between the two Lock areas is formed, wherein by traction to be separated flat Good passes through both lock areas simultaneously and that the separating means comprise a number of separating fingers on the starting plate of the separating medium carrier mon animals are.

A singulation finger, which is positioned opposite the y-direction at a maximum distance from the alignment wall, moves away from the rubber tire of a reel body to the extent that the entire airlock upper is moved with the singling means carrier in the z-direction.

On the one hand, it has been empirically found that this advantageously reduces the risk that a mail piece is pressed against the at least one separating roller of the separating area in the first lock area and another mail piece on the separate separating roller in the second lock area, resulting in double or multiple feeding of mailpieces at the same time can lead into the lock.

On the other hand, it has been empirically found that a stack can be stably held in a peel position by peeling off the lowermost shallow material by two rigidly coupled parallel sheath areas or a wide sheath, resulting in a tilting of subsequent further flat goods (mail items) during peeling off the shed each lowest flat good (mail piece) prevents a stack. Also, this advantage is without the use of vibrating elements and / or other means. The feed deck can be made in one or two parts and extends from the beginning of a transport path for a flat good in the separation area and extends to the end of the transport area of the separation station. In the two-part embodiment, the first part and the second part together have the same width as the mooring of a mooring station.

The Fig. 1 shows a perspective view of a docking station 10 and a separating station 20, from the front left above. The docking station 10 has a vertical alignment wall 11 in an x / z plane and a landing table 12 in an x / y plane of a Cartesian coordinate system. The construction of the docking station 10 has already been in previously unpublished German utility model EN 20 2016 102 202 U1 described in more detail. The dicing station 20 has a vertical alignment wall 21 in an x / z plane and a feed deck 22 in an x / y plane of a Cartesian coordinate system. The vertical alignment wall 21 limits the feed deck 22 in the y direction. The feed deck 22 has a width in the areas of the singulation which is approximately equal to the maximum width W of a mail item C4. After the separation area to the end of the separation station, the landing table can be narrower. The mooring can - as in Fig. 1 shown - consist of several parts. A first part 221 of the feed deck 22 lies at the beginning of a transport path for a flat product in the separation area and extends to the end of the transport area of the separation station 20. A second part 222 of the feed deck 22 is also at the beginning of the transport path and extends with a length L2 spaced apart from the vertical alignment wall 21 parallel to the first part 221. The surfaces of both parts 221 and 222 of the feed deck are at a same height K as that of the landing table in the z direction over a table top. The first part 221 and the second part 222 together have the same width W as the quilt. The second part 222 is located upstream in the separating station 20 and has a smaller length than the first part 221. The first part 221 has a width corresponding to the most common format of the flat goods and abuts with its side edge to the vertical alignment wall 21 of the separating station 20th For example, in the transporting direction x, the part 222 has a length L2 which is less than half the length L1 of the set-up deck. A front half 291 of the housing upper shell 29 is displaceable in the z-direction to a maintenance position and is arranged at a predetermined distance above the first and second part 221, 222 of the feed deck 22. A rear half 292 of the housing upper shell 29 is fixedly mounted on a housing lower shell. Above the first and second parts 221, 222 of the feed deck there is a boom 28 at the aforesaid predetermined distance from the feed deck arranged the separating station 20, which covers from above the separating means. The separating means consist of a number of identically long separating fingers and the associated traction means in the respective separating region, such as roller bodies, on which a tire made of a material with a high coefficient of friction, for example a rubber tire, has been mounted. The separating means and traction means form a lock, which remains closed in the operating state of a minimum deflection of the upper lock part with the Vereinzungsungsmittelträger, as in the case when no flat Good was applied (see also 3a and Fig. 7 ). The first part 221 of the feed deck has - in a manner not shown - upstream of the separating station 20 a number of openings for the separating rollers of the first roller 23a of the separating area in the first lock area at different distances from the vertical alignment wall 21 (FIG. Fig. 7 ), wherein the openings are arranged opposite to the y-direction successively spaced. A reel body 235a farthest from the vertical alignment wall 21 protrudes through an opening 205 in the second part 222 of the feed deck.

A good upstream housing wall of the boom 28 forms a Stapelanschlagswand 281. The boom 28 is fixedly connected to the front half 291 of the housing upper shell 29, wherein the front half 291 on a pressure box 26 (FIG. Figure 3 ) is mounted. As soon as a lock is released by actuation of a button 263, one moves onto a guide rod 276 (FIG. Figure 3 ) inserted compression spring 274 (not shown) the pressure box 26 in the z-direction and the front half 291 of the housing upper shell 29 ( Fig.1 ) with the boom 28 and the front of the separating station 20 enters a maintenance position (not shown). The maintenance position provides good access to the transport path for removal of jams in case of a jam of flat goods or for maintenance. Optionally, upstream of the boom 28, a slide 19, which can be displaced in the y-direction and in the opposite direction, can be arranged on the docking station 10.

The Fig. 2 shows a front view of the docking station 10 and the separation station 20. The slider 19 reaches about 2/3 to 4/5 of the height of the vertical Ausrichtwand 11. The boom 28 opposite a roller body 235a of the separate separating roller protrudes through a corresponding opening of the feed deck 22 (or 222 in Fig.1 ) of the separating station 20 in the z-direction, the roller body - not visible - being mechanically coupled to the driven rotary axle of the first roller 23a of the separating region. Likewise stand out the further roller body of the first roller 23a concealed by this roller body passes through corresponding openings of the feed deck 22 of the separating station 20 in the z-direction ( Figure 7 ). The first roller 23a of the separating region is located in the lower part of the lock of the first lock area and the associated separating fingers are resiliently mounted in the upper part of the lock. In the transport path and immediately following in the transport direction x, a second roller 23b of the singling region, which faces a number of pressure fingers 2682, is arranged downstream of the feedstock. The second roller is located in the bottom lock and the Andruckfinger are spring-mounted and rotatable in the upper lock part. The Andruckfinger also serve to hold flexible flat goods. The second roller 23b improves the traction in the separating region in the transport direction x. It is preferably constructed identically to the first roller 23a. Their rotary axle, however, has the smaller dimensions in length. In the second roller 23b, first, second and third roller bodies 231b, 232b and 233b are also arranged on a structured roller body and equipped with rubber tires. A comparable arrangement of a second roller is already from the German utility model DE 20 2012 011 877 U1 out. In the transport region of the separating station 20, a first and a second transport roller 24 and 25 project through corresponding openings of the feed deck 22 of the separating station 20 in the z-direction.

The Fig. 3a shows a perspective view of the separating station 20, from the front right above, with removed housing upper shell. A first part 221 of the feed deck is bounded in the y direction by the vertical alignment wall 21.
The first roller 23a of the singling area consists - not shown - of a structured roller body with integrated freewheel mechanism whose structures with the largest diameter roller body 231a, 232a and 233a are formed on the respective rubber tires are mounted. The first roller 23a of the singulation area runs - in an in Fig. 7 shown manner - on a driven rotary axle, which also drives a separate fourth roller body 234a with integrated freewheel mechanism and the separate fifth roller body 235a with integrated freewheel mechanism. The roller bodies 231a, 232a, 233a, 234a, each likewise equipped with a mounted tire, pass through an opening in the first part 221 of the feed deck 22, the openings being arranged next to one another in a row opposite to the y direction are. The housing lower shell is at the front by an additional housing part 223 - corresponding to the second part 222 of the feed deck - supplemented, wherein the second part 222 is supported on the additional housing part 223. The additional housing part 223 has an opening, not shown, on its rear side in order to be able to receive the rotary axle 230a of the first roller 23a. Through an opening 205 of the assembled second part 222 of the feed deck protrudes a fifth roller body 235a in the z direction. The fifth roller body 235a is equipped with a rubber tire and connected to a - not shown - separate roller body, which is equipped with an integrated freewheel mechanism and on the driven Drehachswelle 230a runs ( Fig. 7 ). By means of the separating rollers driven in this way, the respectively lowest flat good of a stack of flat goods is pulled through the lock during traction on the basis of traction ( Fig. 4b ).

The rubber-tyred first, second and third roller bodies 231a, 232a, 233a are each flanked on both sides by a total of four separating fingers, which are mounted on the stop plate 265, which is based on the Fig. 7 will be explained in more detail below. Likewise, the fifth roller body 235a is flanked on both sides by the separating fingers 2656, 2655. A spring finger 26575, 26576 is arranged in each case on the separating fingers 2655, 2656 resiliently. The position of all singulation fingers to the corresponding reel body is positionable by an adjustment so that none of the reel body touches the singulation fingers.

A fourth roller body 234a passes through a further opening 204 in the first part 221 of the feed deck in the z-direction at a second distance b opposite to the y-direction away from the vertical alignment wall 21 ( Figure 7 ). Also, this fourth roller body 234a is connected to a - not shown - separate roller body, which is equipped with an integrated freewheel mechanism and runs on the driven Drehachswelle 230a. But this fourth reel body is neither flanked on both sides by separating fingers, nor is the fourth reel body 234a opposed to a different separating means. Rather, the fourth reel body 234a has a gap of length f (FIG. Figure 7 ), in which no separating fingers are mounted.

Alternatively, the first roller 23a of the separating region can also be designed to be elongated in a constructive manner, so that no separate roller body has to be mounted on the rotary axle. Then only one is required and the cost of freewheel mechanism can thus be minimized.

First, second and third roller bodies 231b (not visible), 232b and 233b of the second roller 23b (FIG. Fig.2 ) are also arranged on a structured roller body with freewheel mechanism, on a - in the Fig. 3a not shown - driven rotary axle 230b is running. A comparable arrangement of first, second and third roller bodies on a structured roller body of a second roller 22b of the singling area already goes from the German utility model DE 20 2012 011 877 U1 out.

In the transport path follows on the second roller 23b, a first transport roller 24 in the transport region, wherein the first transport roller 24 faces a first pressure roller 261. The transport path is followed by a second transport roller 25 in the transport area, which faces a second pressure roller 262. The two pressure rollers are mounted resiliently and rotatably mounted in a pressure box 26, which has an opening for a rotation axis 260 a rocker 264 near the center of its front wall. Upon actuation of a mounted on the pressure box 26 button 263 of the pressure box 26 is moved by spring force along a guide rod 276 in the z direction, which also already from the German utility model DE 20 2012 011 877 U1 evident.

The difference is that, firstly, due to an extension of the lever arm length of the rocker about 20% - 40% of a separating medium carrier 267 with separating fingers instead of the second roller (as in DE 20 2012 011 877 U1 ) now faces the first roller 23a in the separating region, wherein the separating fingers mounted on the separating medium carrier, due to the lever law and the force of gravity, press a flat product to be separated more strongly against the first roller 23a. This increases the static friction and improves traction. Secondly, the width of the separating agent carrier 267 in the y-direction is increased to approximately 2/3 to 4/5, preferably 3/4 of the largest post format B4 and now reaches the width W, which increases the probability of an oblique or double feed of reduced such flat goods, which in particular have a large format. Third hold Andruckfinger 2681, 2682 ( 3b ) the flat goods close to the feed deck so that the congestion hazard is reduced. Fourth, a jam can be easily remedied, since the gap of the separating lock with the lifting of the Andruckkastens 26 is increased when the key 263 is actuated. Upon actuation of the button 263 of the separation region and the boom 28 is moved in the z direction. It is envisaged that the gutstrome entrance side Stapelanschlagswand the boom 28 and the feed deck 22 a Vorschleuse for a stack flat Make good. The pre-airlock is also opened at the push of a button to eliminate a jam.

The extension arm 2641 of the rocker 264 has a front side leg 26411 and a rear side leg 26412 offset in the y direction, which are connected to each other by a yoke 26413 arranged upstream. The yoke 26413 of the extension arm 2641 is preferably at a distance from the swing end opposite the other swing end with the rotation axis 260, the distance being large enough to bridge the distance to the first roll 23a. The distance from the axis of rotation 260 is further increased by a holding plate 2642 has two Abstandsdome 2644, 2645 which are attached to the yoke 26413 and the distance of a mounting plate 2673 of the separating medium carrier 267 to the yoke of the extension arm 2641 on. The separating agent carrier 267 has a stop side 2671 lying in the direction of the upstream parallel to the y / z plane. A good upstream stack stop wall of the boom 28 stops a first stack partial quantity of flat goods and drops in one step onto the stop side 2671 (FIG. Fig.1 ) at which a second batch subset of flat goods is stopped. From the stop side 2671, a stop plate is angled on the one hand obliquely to the direction of gravity and in the transport direction x to the feed deck, so that a ramp-like arranged stop plate 265 is formed for flat goods. On the other hand, a bend 2672 is provided in the transport direction x from the upper edge of the abutment side 2671 of the separating medium carrier 267, which has a greater distance from the feed deck and is approximately parallel to the feed deck. This distance to the feed deck is at most equal to the height of about 3 - 5 flat goods of maximum thickness, if there is no flat good in the separating gap. For example, the rollers of the feed deck singulation rollers protrude 5 mm beyond the plane of the feed deck, and the largest distance of the bottom edge of the stop plate 265 is 6 mm to the feed deck plane in the event that no mail pieces are applied and passed through the gate should be. The distance of the lower edge of the stop plate 265 to the feed deck increases in the guided through the gap of the lock when mail pieces according to their thickness. A maximum deflection of the stop plate is at least 45 mm to the feed deck (see 3b ).

The mounting plate 2673 of the separating medium carrier 267 is angled from the end of the bend 2672 in the z direction. A further bend 2674 from the stop side 2671 of the separating medium carrier 267 in the transport direction is provided at the front end of the separating medium carrier 267 for the lateral protection of the separating fingers and to exclude a possible risk of injury to a person who operates the separating station. The frame 27 has a rear wall 272, on which a carrier plate angle 2751 is mounted. A follower pin 26414 on the extension arm 2641 is located near the rocker 264 on the pressure box when there is no flat good in the separating gap.

The Fig. 3b shows a perspective view of the separating station 20, from the front right above, with the upper shell removed in a working phase of the maximum deflection of the rocker by a flat Good with maximum thickness, where in the latter was not shown. The separating agent carrier 267 is mounted on the extension arm 2641 via spacer domes 2644, 2645 formed on the holding plate 2642. The separating medium carrier 267 is aligned parallel to the y-direction and carries all the separating means. Two mounting plates 26581, 26582 are provided for mounting the separating fingers together with leaf springs, which are designed as spring fingers on the stop plate 265. The structure of the singulation fingers is based on the FIG. 5a described in more detail.

Alternatively, the separating fingers on the run-up plate 265 can be mounted together with one each formed as a spring finger leaf spring by means of at least one mounting plate.

A carrier plate angle 2751 is partially visible mounted on the frame rear wall 272. The support plate angle carries a fixed axis 2680, on which a support plate 269 is disposed transversely to the swing guide to the transport direction. A lobe 2695 ( Fig. 5b ) from the support plate 269 centrally in the z-direction in a free area between the distance domes 2644, 2645th There are also two ball bearings 2693, 2694 arranged, which engage in a guide channel 2643 of the holding plate 2642 ( Fig. 5a ).

The carrier plate 269 has in the transport direction x an angled portion 2691 (concealed) and an angled portion 2692, each with an opening 26910 (concealed) and 26920. With the fixed axis 2680, an adjusting means is engaged for adjusting the separating finger position transversely to the transport direction x. The The fixed axle 2680 mounted in the support plate angle 2751 projects through the openings 26910 (concealed) and 26920. At the front end, a fixed axis 2680 has a thread 2684. As adjusting means for the separating fingers, for example, a Justagemutter 2685 is provided (see Fig. 8 ). Advantageously, a simultaneous adjustment of all singulation fingers is possible.

The Fig. 4a shows a schematic representation of a front view of a detail of the landing station and a detail of the separating station, in an applied stack and before separation of the stack. While a first subset of the stack ST abuts flat goods on the abutment plate 265, a second subset of the stack ST of flat goods is stopped by the abutment side 2671 of the singulation medium carrier 267. A third subset of a stack ST of flat goods is stopped by the stack abutment wall 281 of the boom 28 located well upstream of the singulator carrier 267, which is located in the operating mode at a fixed distance from the feed deck. The stop plate 265 goes to the one end downstream in tines, wherein in the Fig. 4a drawn tines 26511 the others covered. In the y direction next to the prong 26511, the singulation finger 2656 with the associated spring finger 26576 and a mounting plate 26582 are arranged. The run-up plate 265 has an edge to another end and merges in the z-direction into a wall of the separating medium carrier 267, which has the stop side 2671 upstream and which is angled in the transporting direction x into a bend 2672. The stop side 2671 has a height h2max up to the aforementioned edge. The bend 2672 merges into a mounting plate 2673 of the separating agent carrier 267. The mounting plate 2673 is angled in the z-direction. By a Z-shaped profile of the separating medium carrier 267 results in a large torsional stiffness of the entire upper lock part. The lower edge of the stack stopper wall 281 is at a height h above the highest point on the circumference of the fifth separating roller 235a.

The fifth separating roller 235a lies in the y-direction adjacent to the separating finger 2656 with the associated spring finger 26576, so that the separating roller 235a overlaps with the separating means (2656, 26576) without a gap. The inclination angle α of the stop plate 265 is in the range of 28 ° - 35 ° and is preferably α = 32 ° to a straight dash-dot line m, the runs parallel to the transport direction x and at a distance m to the feed deck 12 of the docking station or the feed deck 22 of the feed. An imaginary (not shown) vertical line between the aforementioned edge of the stop plate 265 and the aforementioned straight dash-dot line m has a height h1min. The first and second subset of the stack ST of flat goods together have the height h = h1min + h2max and are transmitted under the fixed in the operating mode Stapelanschlagswand 281, wherein the Stapelanschlagswand 281 forms a first lock stage of a pre-sluice. The third subset has the height h3.

Although theoretically the first subset of the stack ST of flat goods may have the height h1min, it is shown schematically in FIG 4a only a first flat good G1 medium thickness. The second subset of the stack ST of flat goods consists of a second flat product G2 having the maximum thickness Dmax. The material G2 is stopped by the abutment side 2671 of the separating agent carrier 267. A third flat good G3 of maximum thickness lies on top of the second flat good G2. Due to its thickness, the material G3 is stopped by the stack stop wall 281, that is, by the first stage of the pre-sluice. Good G3 is followed by Good G4, Good G5, etc. of the third subset of the stack ST of flat goods also stopped by the pre-sluice.

The Fig. 4b shows a schematic representation of a front view of a detail of the landing station and a detail of the separating station, in an applied stack and during a separation of the stack. The separating medium carrier 267 in the upper lock part is raised in accordance with the thickness of the first flat product G1, while the latter is pulled through the lock by traction. At the same time, Good G2 slips against the stop plate 265 and Good G3 hits the stop side 2671, but the other flat goods of the stack slip down in the direction of gravity. By lifting the separating agent carrier 267, the abutment side 2671 of the separating medium carrier 267 is effective only up to a height h2 * <h2max. The Stapelanschlagswand 281 of the boom 28 forms a first immutable stage in the operating mode and the stop side 2671 of the separating agent carrier 267 forms a second variable stage of the pre-sluice. With a maximum thickness of the flat product within the lock - not shown - instead of the G1 medium gauge, the height h2min would be instead of h2 *.

Due to the variable step height h2min <h2 * <h2max decreases with increasing thickness of the separated material according to the risk of stowing on the stop side 2671. The smaller the step height h2 * the lower the risk that a flat Good between the lower edge of the Stapelanschlagswand 281 and the stop side 2671 is clamped.

The Fig. 5a shows a perspective view of a detail of the separating medium carrier of the separating station, from the top right top. The separating medium carrier 267 is mounted on the holding plate 2642, which has an integrally formed guide channel 2643. The separating fingers 2651 to 2654 lie in a first lock area 31 (FIG. Fig. 7 ) and are mounted on the lying in the direction of transport surface of the stop plate 265 together with at least one spring fingers 26571 to 26574. Each spring finger should have a defined spring force. To achieve this, several spring fingers can be mounted one above the other. The spring fingers are punched out at the edge of a thin leaf spring plate or from a stack of thin leaf spring plates, so that the spring fingers are tine-like and comb-like arranged on a remainder of the leaf spring plates and are separately resiliently movable. The four separating fingers 2651, 2652, 2653 and 2654 are made of a flexible resilient material with a high coefficient of friction and are flanked by each comb-like tines arranged on both sides 26501 to 26507 of the stop plate 265. The separating fingers 2651, 2652, 2653 and 2654 are releasably secured by a mounting plate 26581 on the starting plate 265. The separating fingers 2655, 2656 lie in a second lock area 32 (FIG. Fig. 7 ) and are also mounted on the surface of the stopper plate 265 together with a number of spring fingers 26575, 26576. The separating fingers 2655, 2656 are made of the same material as the separating fingers of the first lock area 31 (FIG. Fig. 7 ). The comb-like tines 26508 to 26511 flank the singulation fingers. The separating fingers 2655, 2656 are detachably fastened by a mounting plate 26582. Both lock areas are rigidly connected to the separating agent carrier 267. The separating medium carrier 267 is detachably connected to the holding plate 2642. On the back of the support plate is aligned in the Z direction guide channel 2643, which receives the attached to the support plate 269 to the swing arm bearing 2693, 2694.

The Fig. 5b shows a perspective view of a detail of the carrier plate 269 to the swing guide, from the front left above. Compared to the representation in the FIG. 5a is the support plate 269 to the swing guide, around the z-direction of the Cartesian coordinate system and thereby rotated by 90 ° to the left. On the support plate 269 for swing guide, a tab 2695 is formed, which extends in the z-direction. A first ball bearing 2693 is disposed on the upstream surface of the lobe 2695, and a second ball bearing 2694 is disposed on the upstream surface of the swing arm support plate 269 in the center at the lower edge of the swing guide plate 269. Both ball bearings are aligned in the direction of gravity and fit into the molded guide channel 2643 of the holding plate 2642 Fig. 5a ,

In the Fig. 6 is a plan view of a detail of the separating station shown. An extension arm 2641 is mounted on the rocker 264 upstream. The extension arm 2641 has a front side leg 26411, a rear side leg 26412, a yoke 26413 and a driving pin 26414. On the yoke 26413 of the extension arm 2641 of the rocker 264, a holding plate 2642 is mounted on one side of the separating medium carrier 267. The holding plate 2642 has two spacer domes 2644, 2645 and a guide channel 2643. The spacer domes 2644, 2645 of the support plate 2642 bridge the space between the yoke 26413 and the support plate 2642, for the entire rocker guide channel 2643, and for ball bearings 2693 on the tab 2695 on the rocker support plate. The other side of the separating agent carrier is L-shaped from the extension arm 2641 against the y-direction. The flap 2695 is a centrally located narrow part of the support plate 269 for swinging guide. The tab 2695 protrudes in the z-direction into a free area between the distance domes 2644, 2645. The first ball bearing 2693 on the z-direction upper edge of the tab 2695 is mounted on its upstream surface. A second ball bearing (not visible) is provided at a distance in the direction of gravity on the upstream surface of the support plate 269 to the swing guide.

In the Fig. 7 is a cut detail of the separating station, shown from left. On the driven rotary axle 230a are a structured roller body The first roller 23a is mounted with three roller bodies 231a, 232a, 233a and two identically constructed separate roller bodies 234a, 235a, each equipped with rubber tires having a high coefficient of friction. The structured roller body is arranged under the feed deck or under a part of the feed deck and equipped with integrated freewheel mechanism. The separating fingers 2651 to 2654 and the three roller bodies 231a, 232a, 233a lie in a first lock area 31. The lock area 31 has, for example, a width of at most the width of the C6 format of mail items or at least the width of smallest mail piece formats. The second roller body 232a is formed in the center of the structured roller body of the first roller 23a. The center of the tread of the second roller body 232a is preferably located at a first distance a = 4.5 cm from the vertical alignment wall 21, and the first and third roller bodies 231a and 233a are on both sides of the second roller body 232a on the structured roller body of the first roller 23a educated. The first lock area 31 preferably has the width e = 8.3 cm. Thus, mail pieces of the format B6 and C6 can be safely pulled under the lower edge of the run-up plate 265 and transported in the transport direction x. A fourth reel body 234a is disposed on the rotary axle 230a adjacent to the first gate area 31, for example, at a second distance b about ≥ 2/3 of the width of the C5 format of mail pieces from the vertical alignment wall 21. Preferably, b = 10.7 cm. Thus, mail pieces of the format B5 and C5 can be supported from below and transported in the transport direction x.

The singulation fingers 2655 to 2656 and the separate reel body 235a lie in a second sluice area 32. The center of the run area of the separate fifth reel body 232a is at a third distance c ≦ 3/4 of the width of the B4 format of mail pieces, preferably c = 18, 25 cm away from the vertical alignment wall 21. The second lock area 32 ends at a fourth distance d ≥ 4/5 of the width of the B4 format of mail pieces, preferably at a distance d = 20.15 cm from the vertical alignment wall 21. The second lock area 32 preferably has the width g = 3.8 cm. An edge of the first lock region 31 closest to the vertical alignment wall 21 is preferably at a distance a - e / 2 = (4.5 - 8.3 / 2) cm = 0.35 cm. An edge of the first lock area 31 which is farther from the vertical alignment wall 21 is preferably at a distance a + e / 2 = (4.5 + 8.3 / 2) cm = 8.65 cm. The latter distance a + e / 2 lies from the inside Edge of the second lock area 32 preferably at a distance f = c - g / 2 - (a + e / 2) = 18.25-3.8 / 2 - (4.5 + 8.3 / 2) cm = 16, 35 - 8,65 cm. = 7.7 cm away. Each separate reel body is also equipped with integrated freewheel mechanism. The first, second and third roller bodies 231a, 232a and 233a of the structured roller body of the first roller 23a have a diameter of about 4 cm and are preferably 1.0 to 1.2 cm wide and equidistant from each other. They each protrude through a corresponding opening 201, 202, 203 in the first part 221 of the feed deck. The first distance a is smaller than the second distance b. The second distance b is smaller than the third distance c and the third distance c is smaller than the fourth distance d. It holds that a <b <c <d. The roller body 23a rides on the driven rotary axle 230a. In the first part 221 of the feed deck 22, the openings 201, 202, 203, 204 for first, second, third, fourth reel body and in the second part 222 of the feed deck 22, only one opening 205 for the fifth reel body 235 a is provided. The first, second, third and fifth roller bodies face the separating means to form a lock through which a flat product to be separated passes through traction. The separate fourth roller body 234a passes at a second distance b through a fourth opening 204 in the first part 221 of the feed deck in the z-direction. On the separate fourth reel body 234a, a rubber tire is also mounted. The separate fifth roller body 235a is located at a much larger third distance c from the vertical alignment wall 21 and provided with a fifth rubber tire and passes through a fifth opening 205 in the second part 222. The separate reel bodies 234a and 235a are mounted on the driven rotary axle of the first roller 23a together with each free-wheeling mechanism.

Alternatively, an elongated structured roller body of the first roller 23a can also be used again, which has at least one further roller body structure.

The three rubber tires of the reel bodies 231a, 232a, 233a of the first roller 23a and the singulation fingers 2651 to 2656 are made of a plastic or rubber or other material having a very high coefficient of friction when used with a flat product, the latter preferably comprising pieces of paper or paper Cardboard covers. The remaining tires of the roller bodies 234a, 235a are also made of a plastic or rubber or other material with a very high coefficient of friction.

The Fig. 8 shows a perspective view of the arrangement of the support plate to the swing guide in the separating station, from the top right top. On the support plate 269 to the swing guide right-angled bends 2691, 2692 are provided with one opening 26910, 26920 for a fixed axis 2680 on both sides. The fixed axis 2680 and a fixed Arrettierungsstift 273 for guiding the support plate 269 to the swing guide are mounted on a support plate angle 2751 at a distance side by side. The support plate angle 2751 is mounted on the front of a rear wall 272 of a - not shown - frame. In the mounted state, the first right angle bend 2691 of the swing plate support plate 269 is located closer to the back wall 272 than the second right angle bend 2692 of the swing plate support plate 269.

The first rectangular bend 2691 has, in addition to the opening 26910, a further opening 26911 for the Arretierungsstift 273 for guiding the support plate 269 to the swing guide, wherein the support plate 269 is arranged transversely to the swing guide in the y-direction on the fixed axis 2680 and on the Arrettierungsstift 273 ,

A portion of the fixed axis 2680 is located closer to the support plate angle 2751 and has a larger diameter D1. Two Andruckfinger 2681, 2682 are mounted resiliently and rotatably on this part of the fixed axis, each with a Andruckfingerfeder 26811, 26821.

Another part of the fixed axis 2680 is set at a further distance from the carrier plate angle 2751 and has a smaller diameter D2 than D1. The other part of the fixed axis 2680 is formed bolt-shaped with the smaller diameter D2 and has a bolt thread 2684 at its protruding end. A compression spring 2683 is mounted on this part of the fixed axis 2680 with the smaller diameter D2.

The rocker guide support plate 269 is bent in a U-shape so that an inner wall of the first right angle bend 2691 and an inner wall of the second right bend 2692 face each other and are arranged in parallel. A shoulder to the smaller diameter portion D2 of the fixed axle 2680 forms a first stop for one end of the assembled compression spring 2683 and the inner wall of the second right angle bend 2692 forms a second stop for the other end of the assembled compression spring 2683. An adjustment nut 2685 is mounted on thread 2684, which protrudes through hole 26920. Through the Justagemutter 2685 can the support plate 269 are moved to the swing guide in the y-direction and opposite thereto and the extension arm 2641 pivots according to the adjustment, because in the guide channel of the support plate ball bearings 2693, 2694 run on the sheet metal tab 2695 and on the transversely displaceable support plate 269 to the swing guide are mounted ( 5a ).

If in the present example, a particular embodiment, namely preferably a separating station according to a first variant has been explained in detail, but not another embodiment is excluded by another variant of the scope, which - starting from the same basic idea of the invention - can be used and of the appended claims.
