EP1531948B1 - Device for transferring in a precise position flat objects to be sorted towards the input device of a sorting conveyor - Google Patents

Abstract

The aim of the invention is to develop a device for transferring in a precise position flat objects to be sorted towards the input device of a sorting conveyor for sorting them. Said device also makes it possible to transfer problematic objects to be sorted, for example postal consignments without address, in a sufficiently precise manner for the subsequent treatment thereof. Said aim is achieved by the fact that a picking unit (15) which periodically individualises the flat object (6) for sorting, places said objects (6a) on a transporting path (26), and that a transferring unit (30) transfers said objects to be sorted (6a), when they come in a predetermined position on the transporting path, to an input device (8) at a defined advancement rate. Said targeted advancement rate makes it possible to place the object to be sorted in a final defined position in the input device in such a way that the subsequent treatment thereof, in particular its vertical positioning, is carried out in a reliable and automated manner. The shape and structure of the object to be sorted are not important, because prior to the object reaching the predetermined transport position, the targeted displacement thereof is carried out at an pre-set advancement rate.

Description

The invention relates to a device for the positionally accurate feeding of flat sorting pieces to an input device for a sorting conveyor, such as from US-A-5,860,504 known.

Such a device is commonly used in a sorting conveyor for post automation, such as, for example, in the European patent application EP 827 786 A1 is described. Usually, this sorting conveyor has so-called jetties, which einschiessen the flat sorting pieces in pockets of a rotating conveyor. From these pockets, the flat sorting pieces are emptied out of their respective assigned physical target locations and can be subsequently fed to their destination.

The sorting of flat sorting pieces is comparatively demanding insofar as the dimensions and manageability of flat sorting material varies within wide limits. On the one hand, there is almost an infinite variety of different dimensions in width, height and thickness in terms of format alone. Further, the packaging and rigidity of flat sorting pieces are also found in a very different configuration, which is represented, for example, in a contrasting way by rather hard, rigid cardboard envelopes and by rather soft brochures and magazines packed in foil. Especially problematic to doing so the so-called direct mail, which are usually promotional materials often consist only of a loose-leaf collection with additional inserted and beyond the dimensions of the remaining leaves protruding inserts.

Usually such mail items, but also other flat sorting pieces are inserted in horizontally stored stacks in the above-mentioned feeder and must be deducted individually from these stacks, which in itself is a technically very demanding task. In order to be able to feed these flat sorting pieces, which as a rule are located horizontally, into the circulating sorting conveyor with a jettying device, it is necessary to erect these sorting pieces vertically. However, this placement makes it necessary, in turn, for the sorting pieces to be brought to the device for setting up the sorting pieces in a very precisely positioned position. In this case, it is aggravating that it is precisely the less rigid and less homogenous sorting pieces, e.g. the o.g. Direct mail, particularly difficult to handle and therefore can not be supplied automatically usually, but must be manually positioned by an input space on the feeder, which is a significant cost factor.

The invention is therefore based on the object of specifying a device for the positionally accurate feeding of flat sorting pieces to an input device for a sorting conveyor, which makes it possible to supply the above-mentioned particularly problematic sorting pieces sufficiently accurately for further processing in particular.

This object is achieved according to the invention in the device of the type mentioned by the features of claim 1.

In this way it is ensured that a sorting piece is positioned in the input device due to this targeted feed with a defined end position so that further processing, in particular the vertical placement of the sorting piece, can be carried out safely and automatically. In this case, the format and the nature of the sorting piece without further concern, because with the arrival of the sorting piece at the predetermined location a targeted translation of the sorting takes place by exactly the feed.

In particular, in the case of direct mail items with loose sheet inserts and the like, it is particularly significant that a comparatively stable edge, for example the folded edge, can be arranged in the subsequent setting up of the sorting piece. For this purpose, it provides a particular embodiment of the invention that the sorting pieces, which have a preferred edge, in the deduction unit stackable be deducted and vorvorst lying preferential edge to the conveyor line can be transferred.

A particularly reliable embodiment of this aforementioned feature, it is provided that the trigger unit comprises a drum-like constructed rotatable unit having suction cups and a transport locking element, wherein the suction cups an attack on one of the drum nearest sorting piece is provided and then with the transport locking element an edge, in particular the preferential edge, of the suction cup engaging with the sorting piece is engageable. In this way, the suction cups can suck in a sorting piece located at the bottom in the stack near the edge and, due to the circular path of the drum, from the overlying sorting pieces separate. Subsequently, the transport securing element controlled by the circular movement, for example a lever pressing the sorting piece with the edge against an abutment, grips the sorting piece, which is now pulled out of the stack and conveyed on the circular path to a suitable position.

It is particularly expedient if, for storing the sorting piece on the conveying path for each predeterminable rotational angular distance, the negative pressure of the suction cups again degradable and the transport locking element is removable from the edge. The sorting piece is so freely conveyed on the conveyor line, but this does not necessarily mean that the sorting piece is stored in a horizontal position, since the circular movement of the drum-like unit also allows other layers.

In an expedient embodiment of the invention, the predetermined conveying location can be represented by a light barrier associated with the conveying path and / or by a touch sensor associated with the conveying path. Additionally or alternatively, the predetermined location may be represented at the same time or alternatively by the end of the conveyor line.

A mechanically particularly reliable operable and simply constructed feeding arises when the feeder unit comprises a telescopic unit with a movable carriage, the carriage extends to reach the sorting piece at the predetermined location, and wherein the defined feed corresponds to the predetermined Ausfahrweg. In this case, the extension and also the subsequent retraction can be electromotively, but for example pneumatically activated. According to the control of these activation elements, therefore, the Auszugweg can be changed within appropriate limits, so that the Auszugweg can be quite shorter than the length of the available extract means, such as a pull-out rail.

To ensure that the defined point for the transfer of the sorting piece to the input device is maintained even in continuous automated operation, the slide of the telescope unit is set so that it has returned to its rest position before the sorting piece just ejected following sorting piece reaches the specified location. It should be noted here that the next sorting piece can already be transported over the returning carriage of the telescope unit to the predetermined location. The only important thing is that the carriage has returned to its rest position at least at the time when the sorting piece has reached the predetermined conveying point and thus the imple- mentation of the sorting piece on the carriage is imminent.

In a particularly advantageous embodiment of the telescopic unit of the carriage of the telescopic unit may have a revolving conveyor belt, which is not driven in the ejection movement and driven in the insertion movement. Thus, it is possible that the position of the sorting piece remains unchanged during the ejection movement relative to the carriage and in the insertion movement is supported accordingly by a suitable drive of the conveyor belt, the depositing / transfer of the sorting piece on / to the input device.

Particularly critical for the deposit / transfer of the sorting piece from the carriage to / on the input device is the rearward insertion movement of the carriage. This Rückwarts directed Einschubbegung is relatively equalized for the sorting piece when a drive element for the conveyor belt of the carriage is coupled to the movement of the carriage, wherein for the Ausschubbewegung a freewheel is provided and in the insertion movement of the Speed of the conveyor belt in terms of amount at least largely adapted to the speed of the insertion movement, but has a reverse sign.

1. a) die relative Lage der beiden Rollen innerhalb eines Rollenpaares zueinander ist fest;
2. b) ein Rollenpaar ist ortfest angeordnet und das andere Rollenpaar ist an dem Schlitten befestigt, der die Aus- und Einschubbewegung vollzieht;
3. c) jedes Rollenpaar umfasst mindestens eine mit einem Freilauf ausgestattete Rolle, so dass
   • c1) beim Ausschub des Schlittens das Band nur über die Rollen des ortsfesten Rollenpaares abrollt, und
   • c2) beim Einschub des Schlittens das Band nur über die am Schlitten befestigten Rollen abrollt.

Another particularly advantageous and simply constructed variant for the telescope unit provides a telescope unit comprising at least one system of two roller pairs coupled via a closed belt, which has the following properties:

1. a) the relative position of the two rollers within a pair of rollers to each other is fixed;
2. b) a pair of rollers is fixed in place and the other pair of rollers is attached to the carriage, which performs the extension and insertion movement;
3. c) each roller pair comprises at least one roller equipped with a freewheel, so that
   • c1) during the extension of the carriage, the belt rolls only over the rollers of the fixed pair of rollers, and
   • c2) when inserting the carriage, the tape rolls only on the rollers attached to the carriage.

In this way, not even more separate drive element for driving the tape in the insertion movement are necessary on the carriage, because the tape rolls on insertion according to the backward movement on the two roles of the carriage in the conveying direction and the sorting piece does not feel that the carriage is under removed him. It thus remains exactly in the end position of the Ausschubbewegung, which was highly intended. Thanks to the freewheels provided for each pair of rollers, the band remains unchanged in the region of the carriage during the ejection movement because the belt rolls over the rollers of the fixed pair of rollers during the ejection movement and the rollers of the carriage do not allow the belt to roll over these rollers due to the now blocking freewheel.

In order to be able to transfer the sorting piece particularly well from the conveying path to the carriage, both the conveying path can comprise strip-shaped spaced conveyor belts, at least in the region of the rest position of the carriage of the telescope unit and the carriage, whereby the strip-shaped conveyor belts of the conveying path and of the telescopic extension are arranged alternately. In this way, so to speak, a kind of transfer zone is created, which is at the same time (end) part of the conveyor line and the carriage.

Thus, especially the number of cycles can also be chosen comparatively high, it is already mentioned above, as already mentioned above, to transport sorting pieces in the abovementioned transfer zone even when the carriage is still traveling back. Thus, the influence of the returning carriage on the conveyed in the opposite direction sorting remains negligible, the plane of the strip-shaped bands of the carriage, which serves as a support for the sorting, may be arranged slightly lower than the plane of the strip-shaped bands of the conveyor line in which the Sortierstück is promoted. Only with the ejection of the carriage and the further transport of the sorting piece on the end of the conveyor line out then takes the slide sliding the sorting piece. In this case, this acquisition can be significantly supported by the or the bands of the carriage have an adhesive surface. Additionally or alternatively, the sorting pieces may also be suitably held on the carriage, though not in the strict sense. For this purpose, the sorting pieces can be brought into engagement with a roll-mounted spring element until it reaches the predetermined conveying location, which presses the sorting piece onto the strip (s) of the carriage (lightly).

Another feature that supports the transfer from the conveying path to the carriage can be achieved if the slide of the telescope unit is adjusted such that the carriage, when transferring the sorting piece from the conveying path to the carriage, at least approximately conveys the speed of the transport path Sorting piece has. Thus, no difference occurs in the relative velocities at the transition of the sorting piece from the conveyor line to the carriage, resulting in no undesired displacements of the sorting piece on the carriage. Such displacements could otherwise result, for example, in accelerating the carriage from the rest position with already resting sorting piece.

A very differently to the above-described solutions to the problem solution provides an embodiment of the feed unit with a disc-like, rotating, non-rotationally symmetrical conveying element, which attacks with its achsferneren areas on the sorting pieces that have reached the predetermined location, and in this way the Feed to the input device causes until the achsnäheren areas lose the attack on the sorting piece. In this way, the sorting pieces are drawn along by the conveying element as long as the regions remote from the axis engage the sorting piece, so that a defined feed can also be achieved in this way. Depending on the thickness of the sorting pieces, a height adjustment may be provided for the conveying element, so that as a result differently sized sorting pieces nevertheless remain in engagement with the conveying element for the same length of time. Likewise, a swash plate can also be provided in the same manner, which, due to its imbalance, also only engages the sorting piece per revolution for a certain period of time and thus ensures a defined feed of the sorting piece.

Further advantageous embodiments of the invention can be found in the remaining subclaims.

FIG. 1 shows a schematic representation of a plan view of a first positioning device 2, with which flat located in a horizontal stack 4 sorting pieces 6 at a partially shown input device 8 are transferred positionally accurate. The positionally accurate transfer is so eminently important because the sorting pieces 6 are then rotated in the part of the input device 8 shown here from the horizontal to the vertical position and then injected with a jar not shown here in pockets of a sorting conveyor also not shown here , Because these aforementioned process steps for sorting the sorting pieces 6 take place with a comparatively high sorting speed, it therefore makes sense that the sorting pieces 6 have to be able to be handled very precisely at any time.

The operation of the first positioning device 2 will now be described with reference to Figures 1 and 2 described, whereby this way of working in principle so also for in the FIGS. 3 and 4 shown second positioning device 10 and a in the FIGS. 5 and 6 closer described third positioning device 12 applies.

The flat sorting pieces 6 are in the embodiment in the format DIN A4 folded advertising leaflets in which one or more loose slip sheets are inserted. The prospectus are not stapled, but only as Loseblattsammlung intertwined. It is easy to see that such sorting pieces 6 are extremely difficult to handle, because they provide otherwise no attack points for a positionally accurate automated transport with the exception of the folded edge, which is hereinafter referred to as preferred edge 14.

These sorting pieces 6 are now stored in the stack 4 on a separating drum 16 on a tray 18. The separating stream is a part of a deduction unit 15, which is within the dashed lines in FIG. 2 discontinued for better understanding enlarged is shown. The respectively lowest sorting piece 6a is then actively sucked from below by means of suction cups 20, which are arranged on the rotating separating drum 16, and thus initially deflected out of the stack 4 downwards. At the same time, the sucked sorting piece 6a is pressed at its preferential edge 14 by means of a lever 22 onto an abutment 24 arranged on the singling drum 16, so that the sucked sorting piece 6a clamped with the lever 22 now follows the circular movement of the singling drum 16. After a rotation of 180 °, the negative pressure in the suction cups 20 is released again and the lever 22 is pivoted away from the counter bearing 24, so that the sorting piece 6a which has been separated in this way is now transferred to a conveying path 26, which by means of strip-shaped conveyor belts 28 separates the sorting piece 6a promotes to a telescope unit 30.

The telescopic unit 30 is in below individually to the FIGS. 7 and 8 described. At this point, only so much is said for explanation, that a movable carriage 32 of the telescope unit 30 at the speed of the last arranged in the conveyor section 26 strip-shaped belts 28 'of the conveyor line 26 extends, ie thus performs a Ausschubbewegung when the preferred edge 14 of Sorting piece 6a reaches a photocell 34. The carriage 32, which also has strip-shaped conveyor belt systems 38, puts back a defined feed distance and places when retracting, ie at the completion of the backward insertion movement, the sorting piece 6a on a conveyor belt 36 of the input device 8, from where it then is transported in the direction perpendicular to the previous conveying direction in the input device 8 and rotated in the vertical direction. In this case, a rolling element 42 is additionally provided, which always presses on the conveyor belt 36 when just the sorting piece 6a is stored, which contributes to the further preservation of the exact storage location for the sorting piece 6a.

In order to be able to perform the positioning of the sorting piece 6a on the conveyor belt 6 with exact position, i. In detail, that the preferred edge 14 always comes to rest at the same location, it is provided in the insertion movement, that the backward movement of the carriage 32 is leveled by a rolling of the conveyor belt systems 38 on the leading edge 14 near the leading edge 40. It is thus a particular feature of the present invention that the relative position of the preferred edge 14 to the front edge 40 of the carriage 32 remains unchanged during the Ausschubbewegung and retracts the leading edge 40 in the insertion movement relative to the preferential edge 14, but this for the sorting piece 6a through the over the leading edge 40 rolling conveyor belt system 38 is relatively equalized. In this way, the positionally accurate position of the sorting piece 6a is maintained even during the insertion movement of the carriage, which is of great importance for the further conveyance of the sorting piece 6a and an essential goal intended with the positioning device 2.

The comparison with the first positioning 2 only slightly modified second positioning can be based on the FIGS. 3 and 4 clearly recognize that in principle only the course of the conveyor line 26 has changed. To save space in width, the available height is used and the separated with the singling drum 16 sorting pieces 6a are first a piece vertically, then horizontally and finally obliquely down to the telescope unit 30 introduced. Here, too, a light barrier, not shown here, is again provided, the reaching of which leads from a sorting piece 6a to the extension of the carriage 32. In addition to the components of the telescope unit 30 shown so far, a pneumatic unit 44 is now shown with a ram 46 driven by it, which is coupled to the carriage 32. The pneumatic unit 44 could also be replaced by an electromotive drive for the plunger 46, which could allow under normal circumstances, a quieter operation. As in the previous embodiment variant, the telescope unit 30 is also shown in the extended position when the second positioning device 10.

The third positioning device 12, which is slightly modified compared to the first and the second positioning device 2 or 10, can be left according to FIGS FIGS. 5 and 6 clearly recognize that the sorting piece 6a is passed here in a direction perpendicular to the carriage 32 of the telescope unit 30. In this way, this embodiment makes it possible to simplify the input device 8 in such a way that the conveying section for rotating the sorting pieces 6a from the horizontal to the vertical position has become obsolete. In principle, however, nothing changes with respect to the guidance and the achievement of the feed by the ejection movement of the carriage 32 in this variant as compared to the preceding two variants.

A particularly preferred embodiment for the telescope unit 30 show the FIGS. 7 and 8 in a schematic representation. According to this embodiment, the telescope unit 30 comprises a plurality of conveyor belt systems 38, each of which constitutes a conveyor belt strip. Based on one of these conveyor belt systems 38, the operation will be explained below. Each conveyor belt system 38 has two pairs of rollers 48, 50 coupled by a closed band 38 ', each having two rollers 48a, 48b, 50a, and 50b. The relative position of the two rollers 48a and 48b or 50a and 50b within a roller pair 48, 50 fixed to each other. The pair of rollers 48 is fixedly disposed on the telescopic unit 30 and the other pair of rollers 50 is fixed to the carriage 32, which is the Ausschubbewegung in the direction of an arrow 52 and the insertion movement in the direction of an arrow 54 completes.

In the embodiment, the rollers 48b and 50b each have a freewheel, wherein the roller 48b are locked counterclockwise and the roller 50b in the clockwise direction. As a result, when the carriage 32 is ejected, the belt 38 'rolls only over the rollers 48a and 48b of the stationary roller pair 48, both rollers 48a and 48b rolling in a clockwise direction. In this way, the sorting piece 6a, once it has reached the light barrier 34, no longer changes its position relative to the roller 50a during the ejection movement, which is highly intended. Desirable, this configuration is different in the insertion movement, in which the belt 38 'rolls only on the carriage 32 mounted on the rollers 50a and 50b, the roller 50a in a clockwise direction and the roller 50b run counterclockwise. Thus, the sorting piece 6a "does not" feel it at all during the insertion movement, but retains its end position achieved with the ejection movement as desired. The preferred edge 14 of the sorting piece 6a thus always comes exactly to the desired location on the input device 8 to lie. In order to support this process, in each case a spring plate 58 mounted with rollers 56 is provided, which easily presses the sorting piece 6a on the adhesive conveyor belt 38 'during the ejection movement and rolls back on the sorting piece 6a without friction with the sorting piece 6a.

It is also very clear to recognize that the conveyor belt 38 'is a little below the conveyor belt 28', which can still be regarded as belonging to the conveyor line 26, is arranged so that even when entering carriage 32 already above a new sorting piece 6a to the Light barrier 34 can be brought. This area can therefore be regarded as a type of transfer zone for the transition from the conveyor line 26 to the telescope unit 30.
