    The invention relates to a method for collecting flat and in particular sheet-like goods in the form of a stack in a collecting device and a collecting device and their use for collecting flat goods in the form of a stack.
    Collection devices for collecting flat goods, such as e.g. Sheets or envelopes made of paper or flat cards made of cardboard or plastic, and to form stacks of goods from individual goods or subgroups of such goods are widely known from the prior art. For example, collating webs can be used for this purpose, which have a conveying device with a plurality of collection areas arranged one behind the other, in which the goods can be deposited in a stack and transported away from the conveying device. The goods are stored in landing stations, which are arranged above and along the conveyor so that the goods can be stored in the defined collection areas. Such a gathering web is known, for example, from US Pat. No. 4,177,979 B. The collection of flat goods in the form of stacks by means of such a gathering track, however, proves to be time-consuming and not very flexible. To store the goods in a predetermined collection area of the gathering path, the function of the investors must be synchronized with the movement of the conveyor, for example via a complex mechanical coupling, as described in US Pat. No. 4,177,979, so that the investors can correctly position the goods stored therein given collection points of the gathering can store. The known gathering webs allow only stacking of the goods in a stacking direction from bottom to top, that is, with a gathering web, the goods can only be collected in an ascending direction in the form of a stack of goods and deposited in the collection points of the gathering web.
    Furthermore, stationary collecting stations are known from the art, which can accommodate serially supplied goods, which are collected in the form of a stack and then transported away. With such stationary collection stations, the supplied goods can also be collected only in ascending order of their delivery to the collection station in the stack. The formation of subgroups is possible.
    To flat goods, such as. Leaves in descending order, ie, to be able to stack from top to bottom, collecting devices with movable switching elements are known from the prior art, which transported along a transport path serially transported goods in different directions can deflect, so that the deflected from the original direction of transport goods can either be placed on the top of a deposited already in a collecting compartment sub-stack or pushed under the sub-stack. This allows the goods to be collected in the stack in ascending as well as descending order. Such collection devices are known for example from DE 9 301 072 U1 and EP 0 655 983 B1. However, these collection devices with a switchable deflection device are complex in structure and error-prone in operation. A group or subgroup of several individual sheets can only be pushed with difficulty under an already pre-collected part of the stack, for example. When the leaves have holes or recesses. Due to the weight of the sub-stack and a high friction between the top of the sub-stack to be pushed Guts or subgroup and the bottom of the already deposited sub-stack, it often proves difficult to insert the goods or groups of goods without buckling under the sub-stack. Difficulties occur in descending collecting in such collection devices especially in folded sheets, especially if they have different folding lengths. Submerging a subset of folded sheets or a single folded sheet under a pre-stacked sub-stack may cause the folded sheets to interlock with each other, eventually leading to sheet jamming in the collection device or damage to the sheets.
    From US 5,435,534 a device and a method for folding and collecting paper sheets is known, wherein the paper sheets are first supplied individually by means of a conveyor of a dual collector. The dual collecting device comprises two collecting compartments arranged one above the other, which each define a collecting level. For inserting a paper sheet fed by the conveyor into one or the other collecting compartment, a switchable guide element is arranged between the conveying device and the collecting compartments, which guides the incoming paper sheets either into the upper or the lower collecting compartment. Downstream of the dual collection device, a folding device is arranged, with which the sheets collected in the dual collection device in the form of sheet stacks can be folded. Since the folding device can fold only stacks of sheets with a limited height, a total group of sheets, which is to be inserted, for example in folded form in an envelope, first divided by placing in the two collection compartments of the dual collection device into two subgroups, where a first subgroup is stored in the upper collecting compartment and a second sub-group in the lower collecting compartment of the dual collecting device each in the form of a stack. After dividing the group of sheets into the first and the second subgroup, the second subgroup is first removed from the lower collecting tray and fed to the downstream folding device, in which the first subgroup is folded and then transferred to another collecting device with a single collecting tray. Thereafter, the first subgroup is removed from the upper collecting compartment of the dual collecting device and fed to the folding device, in which then the first subgroup is folded and finally deposited on the folded stack of the second subgroup in the further collecting device. The stacks of sheets deposited in the collection compartments of the dual collection device are successively transported away from the respective collection compartment and fed to the downstream folding device. This is time consuming and slows down the process of piling up. This reduces the throughput of the collecting device.
    Proceeding from this, the present invention seeks to provide an improved method for collecting flat and especially sheet-shaped goods in the form of stacks and a collection device with which the most efficient way and with the highest possible throughput with low error rate a reliable collection of flat goods in stack form is made possible. The collecting device should have as simple as possible, low-maintenance and less error-prone construction and allow the stacking of serially supplied goods in both ascending and descending order. With the method and the collecting device also subgroups of flat goods and in particular also folded sheets or sub-groups of folded sheets in stack form should be able to be collected.
    These objects are achieved with a method for collecting flat goods in the form of a stack having the features of claim 1, a collecting device with the features of claim 12 and the use of a collecting device having the features of claim 11. Preferred embodiments of the inventive Method and the inventive collecting device can be found in the dependent claims.
    The collecting device according to the invention comprises at least two collecting compartments arranged one above the other in a vertical direction, which each form a collecting plane, wherein the collecting planes extend at a distance and preferably parallel to one another. Each collecting compartment expediently has at least one flat shelf at least substantially horizontal, the surface of which defines the collecting level for placing the goods or sub-groups of goods.
    The collection device according to the invention further comprises a supply device for supplying individual goods or prefabricated sub-groups from a plurality of goods to the collecting compartments. The goods are flat and especially sheet-shaped goods, such as sheets of paper, especially in printed form. The goods may also be folded sheets or other flat goods such as e.g. Cards made of cardboard or plastic act. The goods may be, for example, printed and possibly folded paper sheets which form the content of a mail item and include a cover letter with a recipient address and associated attachments. The content of such a mail piece can be collected with the collecting device according to the invention to form a stack of sheets and then inserted into an envelope by means of an inserter. The cover letter of such a mail item with the printed recipient address represents a leading document in the stack, which expediently comes to rest on the top or bottom of the stack so that the printed recipient address is visible on the top or the bottom of the stack , This is expedient, for example, if the stack of sheets forming a mail item is inserted into an envelope with a viewing window.
    In the collecting device according to the invention, the supply device and the collecting compartments are movable relative to each other or pivotable. This makes it possible to introduce individual goods or prefabricated sub-groups of goods, which are felt by means of the feeder to the collection compartments, in a specific and predetermined collection tray and store there. For this purpose, for example, the supply device can be moved in the vertical direction with respect to the stationary collecting compartments or pivoted in its angular orientation with respect to the horizontal. A method or pivoting of the feed device and the collection compartments relative to one another makes it possible for the goods or the sub-groups, which are supplied by the supply device, to be deposited in a (random) predetermined collection compartment. In this way, it is possible, for example, to deposit the goods or product groups supplied serially by the supply device in ascending or descending order in the collecting compartments arranged one above the other. This enables both an ascending and descending collection of the goods in the stack to be formed with respect to the transport order in which the individual goods or the sub-groups are fed from the supply device to the collection compartments in succession. The order of filling the collecting compartments is arbitrarily possible and changeable with the collecting device according to the invention. In particular, the order of filling the collecting compartments is thus independent of the arrangement and order of the collection compartments stacked in a vertical direction.
    For transporting the stored in the collection compartments goods or sub-groups of goods, the collecting device according to the invention comprises a conveyor. This expediently has one or more conveying element (s) for transporting the goods or subgroups out of the filled collecting compartments. According to the invention, the conveyor is designed so that it pushes out the stored in the collected collection compartments goods or sub-groups of goods all at the same time from the collection compartments. For this purpose, at least one movable conveying element is expediently provided, which simultaneously engages in all collecting compartments at predetermined times and pushes out the goods or sub-groups stored therein all at the same time from the collecting compartments. The movable conveying element may, for example, be a slide which is fastened to a movable belt or belt. Upon movement of the belt or the band attached to the slide moves simultaneously into all collection compartments and pushes the goods or sub-groups located therein all at the same time out of the collection compartments.
    Alternatively, it can also be provided that each collecting tray or a plurality of collecting compartments is assigned a single conveyor element, wherein the individual conveyor elements are coupled together so that their movement is synchronized with each other in such a way that all conveyor elements at the same time in retract the collective subject assigned to them and push out the goods or subgroups within it all at the same time.
    The simultaneous removal of the goods located in the individual collection compartments goods or subgroups allows a very efficient collection of goods in the form of a stack and a very high throughput of the collection device. When transporting the goods or sub-groups from the filled collection compartments, the individual stacks are stacked from the individual collection compartments in the form of a stack and conveniently transferred to a downstream of the collection compartments arranged Stapelübernahmeeinrichtung. The stack transfer device expediently comprises a transport device for removing the stack formed. Furthermore, a bushing is expediently provided in the stack transfer device, which has a resilient element and a stationary element, by means of which the stack formed during the removal of the goods or sub-groups from the filled collecting compartments is carried out. The resilient element is preferably biased relative to the stationary element, for example by a spring element or an elastic element such as a spring element. a rubber or foam roller, and the stationary member is formed resistant to deformation at least compared to the resilient element and suspended immovably. When passing the packaged goods or groups of goods through the feedthrough, the stack presses the resilient element against the bias and thereby opens or enlarges a gap between the movable element and the stationary element, through which the stack can then be passed. It is also possible to arrange on both sides of the passage a resilient element, which are pressed away from each other during the passage of the stack in order to open or enlarge the gap between the two resilient elements.
    In order to ensure a uniform alignment of the individual goods or sub-groups of goods in stack form in the individual collection compartments, the collecting device expediently one or more stop elements, which engage in depositing the goods or sub-groups in the collection compartments and form a stop there in which the leading edge of the goods or groups of goods introduced in the collecting compartment comes to rest when it is deposited. For this purpose, a single stop element may be provided, which simultaneously engages in all collecting compartments or it can also be provided a plurality of stop elements, each collecting compartment is associated with such a stop element. When placing the goods or groups of goods in a collecting compartment first comes the front edge of the estate or subgroup in abutment with the stop of the respective collection compartment and usually bounces off from there to the shelf of each collection tray or on the already on it to fall partial stack.
    As the or each conveyor element and the or each stop element can be retracted into the collecting compartments and formed out of the collecting compartments again. Suitably, the or each stop element is formed by a stopper which is attached to a revolving belt or belt and engages in one or each collecting compartment when the revolving belt or the circulating belt is moved to a corresponding engagement position.

    In Fig. 1, an inventive collecting device for collecting flat, in particular sheet-shaped goods in the form of a stack is shown schematically. The collecting device 1 has a supply device 5 for feeding individual goods G or prefabricated subgroups G of a plurality of such goods. A subgroup G may, for example, be composed of 1 to 20 individual items and is already supplied by the feeder 5 as a prefabricated subgroup G in the form of a stack of goods. The individual goods G or Güterteilgruppen G, which may also be present as folded sheets or as a folded subgroup, are transported in the feed device 5 serially along a transport direction. The supply device 5 expediently comprises a first, not shown here in the drawing transport path, which is at least substantially in a horizontal plane, along which the goods G or the Güterteilgruppen G by means of a transport device, such as a conveyor belt or transport rollers, are transported. The supply device 5 further comprises a downstream of the first transport path transport element 6, which in the exemplary embodiment illustrated here two each on rollers 6c circulating conveyor belts 6a, 6b, which are set by the driven rollers 6c in motion. The upper strand of the lower band 6a and the lower strand of the upper band 6b are arranged at a distance and parallel to each other, so that there is a transport gap therebetween through which the goods G or the Güterteilgruppen G along a transport direction T can be transported.
    The transport element 6 is designed to be pivotable in the illustrated embodiment and for this purpose has a pivotable about a pivot axis A frame part 6d, which is shown in Fig. 2. For reasons of clarity, the pivotable frame part 6d is not shown in FIG. 1 and conceals in FIG. 2 the conveyor belts 6a, 6b arranged behind it. The rollers 6c of the circulating conveyor belts 6a, 6b are rotatably arranged on the pivotable frame part 6d. The pivotable frame member 6d is pivotally hinged to a stationary frame member 6e. The pivot axis A is arranged at the upstream end of the transport element 6. At the downstream end of the transport element 6, a pivoting mechanism is provided, which is formed in the embodiment shown here by an eccentric with an eccentric 6f and an eccentric rod 6g applied thereto. The eccentric 6f driven by an eccentric drive not shown here is rotatably mounted on the stationary frame part 6e. The lower end of the eccentric rod 6g is pivoted on the eccentric 6f in the region of its outer periphery and the upper end of the eccentric rod 6g is rotatably mounted on the pivotable frame part 6d. By rotating the eccentric wheel 6f, the pivotable frame part 6d can be pivoted relative to the fixed frame part 6e within a predetermined angular range (with respect to the horizontal plane). By pivoting the pivotable frame part 6d, the position and in particular the tilting of the conveyor belts 6a, 6b with respect to the horizontal plane and thereby the transport direction T of the transport element 6 can be adjusted.
    As can be seen from FIGS. 1 and 2, downstream of the transport element 6, an arrangement with a plurality of collecting compartments a, b, c, d, e adjoins. The collecting compartments a, b, c, d, e are arranged one above the other in the vertical direction and each have a flat shelf 9, the surface of which forms a collecting level. The collection levels of the collection compartments a, b, c, d, e are thus arranged in the vertical direction at a distance and parallel to each other, wherein the collection levels are suitably at least substantially horizontal. The collection levels of the individual collection compartments a, b, c, d, e are used to rest the goods G or the Güterteilgruppen G, which are supplied from the feed device 5 and in particular from the transport element 6. By the pivotability of the transport element 6 (in particular of the pivotable frame part 6d), it is possible that the goods G or goods subgroups G supplied by the transport element 6 can be introduced into an arbitrarily selectable collection compartment a, b, c, d, e.
    In Fig. 3a, the pivotable transport element 6 is shown for clarity in a first position in which a transported by the transport element 6 in the transport direction T Good G is inserted into the lowest collection compartment a. For this purpose, the pivotable frame part 6d (Fig. 2) is pivoted to its lowermost position, in which the downstream end of the transport gap formed between the belts 6a and 6b is at least approximately at the same height (with respect to the vertical direction) as the collecting plane of lowest collection compartment a. A guided by means of the transport element 6 in the transport direction T Good G is thus introduced in this position of the transport element 6 in the lowest collection compartment a and stored there.
    In order to allow for the storage of goods G or Güterteilgruppen G in a collecting compartment a, b, c, d, e a uniform orientation of the there stored goods or groups of goods subdivisions, is in each compartments a, b, c, d, e a stop element 2 is provided, which engages in the respective collecting compartment and there forms a stop 12a, 12b, 12c, 12d, 12e, on which comes when depositing the goods G or the Güterteilgruppen G whose front edge V to the plant. In Fig. 3b, a phase of the inventive method is shown, in which the lowest collection compartments a, b, c and d are already filled with goods G whose front edge V at the respective stop 12a, 12b, 12c, 12d of the associated collecting compartment a, b, c, d is present. When introducing the goods G or Güterteilgruppen G in one of the collection compartments a, b, c, d, e, the leading edge V of Guts G or Güterteilgruppe G first comes into contact with the stop 12a, 12b, 12c, 12d, 12e and then bounces off. The good G introduced into a collecting compartment a, b, c, d, e or the good-part group G introduced therein then falls onto the shelf 9 of the respective collecting compartment a, b, c, d, e or onto a partial stack already deposited thereon of goods G.
    The stop element 2 may be, for example, a stopper 2 which is fastened to a circumferential stopper band 2. The circulating stopper belt 2 is guided - as shown in the figures - around rollers 2, which are driven by a stopper drive. As a result, the stop element 2 can be moved out into the collecting compartments a, b, c, d, e and again out of the collecting compartments a, b, c, d, e. It is possible to provide a single stop element 2 (in particular a single stopper 2) which can simultaneously engage in all or at least in a plurality of adjacent collection compartments. However, it is also possible to assign each collecting compartment a stop element, for example a stopper 2, which engages only in the respective associated collecting compartment and there forms a stop 12a, 12b, 12c, 12d, 12e. In the illustrated embodiment, a lower stop element 2a and an upper stop element 2b are provided, wherein the lower stop element 2a can engage in the lower collection compartments a, b and c and the upper stop element 2b in the upper collection compartments c, d and e. At each Stopperband 2 while several stoppers 2 can be secured in the longitudinal direction of the stopper band at a distance from each other. In the illustrated embodiment, two stoppers 2 are arranged on each stopper band 2. This makes it possible to move the stopper band 2 only in one direction without having to make a change of direction in order to bring a stopper 2 in or out of engagement with an associated collecting tray. The one or more stoppers 2 can be conveniently set at any position in the longitudinal direction (conveying direction) of the collecting compartments. This makes it possible to adapt the position of the stop 2a, 2b, 2c, 2d, 2e in the collecting compartments to the format of the goods, in particular their extent in the conveying direction.
    In order to store individual goods G or Güterteilgruppen G in the collection tray a above the lowest collection compartment a to e, the pivotable transport element 6 is pivoted so that its downstream end comes to rest in the vertical direction at the level of the collecting compartment, in which the goods G or the goods subgroups G are to be inserted. In Fig. 3b, for example, a position of the pivotable transport element 6 is shown, in which the goods G can be introduced into the top collecting tray e. The underlying collection compartments a, b, c, d are already filled with goods G or Güterteilgruppen G and its leading edge V is located on the stop 12a, 12b, 12c, 12d of the respective collecting compartment a, b, c, d.
    If all goods G, which are part of a group of goods to be collected in a predetermined order in the collection compartments a, b, c, d, e have been inserted, all collection compartments a, b, c, d, e are simultaneously emptied by by means of a conveyor which are stored in the filled collection compartments a, b, c, d, e goods G or Güterteilgruppen G are all pushed out of the collection compartments at the same time. For removal of the goods from the collecting compartments a, b, c, d, e, the conveyor expediently comprises a movable conveying element 3, which engages in the collecting compartments to push out the goods stored therein (all at the same time). It is possible to provide a single movable conveying element 3, which simultaneously engages in all collecting compartments and pushes the goods stored in the collecting compartments all at the same time out of the collecting compartments by methods along a downstream conveying direction. However, it is also possible to provide two or more conveying elements 3a, 3b, whose movement is coupled and synchronized with each other so that all conveying elements 3a, 3b at the same time in the collecting compartments a, b, c, d, e engage and through the collecting compartment in order to ensure that the goods stored in the collection compartments are all removed from the collection compartments at the same time. In the exemplary embodiment illustrated here, a lower conveyor element 3a and an upper conveyor element 3b are provided, wherein the lower conveyor element 3a in the lower collection compartments (a, b, c) and the upper conveyor element 3b in the upper collection compartments (c, d, e ) intervenes. Both the lower conveyor element 3a and the upper conveyor element 3b in this case comprises a slide element 3, which is attached to a rotating slide belt 3. The rotating slide belt 3 is felt via drivable rollers 3 and set in drive the rollers 3 »in motion.
    For transporting the individual goods G or Güterteilgruppen G from the filled collection compartments at predetermined times, the movable conveyor elements 3 and 3 a, 3 b set and controlled so that they engage at the same time in the collection compartments and through the collection compartments be moved through, while at the same time push out the goods or groups of goods stored therein from the filled collection compartments at the same time. If a plurality of movable conveying elements 3 a, 3 b are provided, their movement is synchronized so that all conveying elements 3a, 3b at the same time engage in their associated collection compartments. In the above-mentioned embodiment, in which a single movable conveying element 3 is provided, the simultaneous engagement of this conveying element 3 takes place in all collecting compartments a, b, c, d, e automatically.
    At each slide band 3, a plurality of slides 3 may be secured in the longitudinal direction of the band at a distance from each other. In. The illustrated embodiment, two slides 3 are arranged on each slider band 3 in each case. This makes it possible to move the slider belt 3 in one direction only, without having to make a change of direction in order to bring a slider 3 in or out of engagement with an associated collection tray can. This contributes to an increase in the throughput, because the additional slide 3 can already be used for the removal of the next stack from the collecting compartments, after the first slide 3 has been disengaged from the collecting compartments.
    Thus, the stop elements 2 and 2a, 2b do not constitute an obstacle to the removal of goods from the collection compartments, these are moved out before the removal of goods from the collection compartments. In Fig. 4, the collection device 1 is shown in a position in which the collection compartments a, b, c, d, e filled with goods G and the goods are ready for removal. In the position shown in Fig. 4, the stop elements 2 and in particular the stopper 2 are still in engagement with the collecting compartments a, b, c, d, e. For the removal of the goods G from the collection compartments a, b, c, d, e are first the stop elements 2, in particular the stopper 2 moved out of the collection compartments. Subsequently or simultaneously, the conveying elements 3, in particular the slides 3, travel into the upstream end of the collecting compartments a, b, c, d, e and through the collecting compartments in the downstream direction. The stored in the collection compartments a, b, c, d, e goods are all simultaneously pushed in the conveying direction to the downstream end of the collection compartments.
    At the downstream end of the collection compartments a, b, c, d, e, a Stapelübernahmeeinrichtung 4 is arranged. In the exemplary embodiment illustrated here, this comprises a lower conveyor 4a and an upper conveyor 4b, each of which has a circulating conveyor belt 4 around driven rollers 4, the lower conveyor belt 4 obliquely upwards and the upper conveyor belt 4 obliquely downwards is inclined, respectively, seen in the downstream direction and in relation to the horizontal. The upper conveyor 4b in this case comprises a resilient element 7a, which is formed by the downstream roller 4 ». This resilient element 7b is biased by a spring element 8 against a stationary element 7a. The stationary element 7a is formed by the downstream roller 4 "of the lower conveyor 4a. The stationary element 7a and the resilient element 7b are arranged in a basic position at a distance from one another, so that a gap is formed between the stationary element 7a and the movable element 7b. This gap forms a passage 7, through which the stack formed by the collecting device 1, which forms a finished goods group, can be carried out for the removal of the stack.
    In Fig. 5, two successive stages of the removal of the goods from the collection compartments a, b, c, d, e and thereby taking place formation of the stack S and the removal of the formed stack S are shown. 5a shows how the goods G located in the collecting compartments a, b, c, d, e are pushed out of the conveying element 3 or the two conveying elements 3a, 3b all at the same time from the collecting compartments in the downstream direction , Due to the resulting from the drawings of Fig. 5 inclined position of the conveyor belts 4a, 4b obliquely upwards or obliquely down the led out of the collecting compartments goods G are fed to each other to form a stack S in the vertical direction and from the in a transport direction T. moving conveyor belts 4 passed through the passage 7, which is formed by the gap between the stationary member 7a and the movable member 7b. In this case, the resilient element 7b is pressed against the restoring force of the spring element 8 upwards. The restoring force of the spring element 8 or the elastic property of the resilient element 7b ensures that the goods G forming the stack S are pressed firmly against one another and compressed in this way into the stack S. Downstream of the feedthrough 7 there is a removal device 19 for the removal of the formed stack S (FIG. 1).
    FIGS. 6 and 7 show a preferred embodiment of a collecting device according to the invention. In this arrangement, each collecting compartment a, b, c, d, e has two separate shelves 9, 9. The shelves 9, 9 of a collecting compartment a, b, c, d, e are arranged transversely to the transport direction at a distance from each other, so that between the shelves 9, 9 a collecting compartment creates a gap. In this gap, the conveyor is arranged with the conveyor elements 3 and 3a and 3b for the removal of goods from the collection compartments. In particular, in this gap, the lower conveyor element 3a and the upper conveyor element 3b arranged with the respective covered by these sliders 3, which pass through the collection levels of the collection compartments a, b, c, d, e. In each of the shelves 9, 9 of a collecting compartment a, b, c, d, e is a slot 9a, 9a 'provided by a movable stop element 2, in particular the stopper 2, pass through and thereby into the respective collecting compartment a, b, c, d, e can intervene. The two shelves 9, 9 of a collecting compartment a, b, c, d, e are expediently displaceable relative to one another transversely to the transport direction. This allows, for example, an exchange of the stop elements 2 and / or the conveying elements 3; 3a, 3b, if they should be damaged by wear. Furthermore, by the displaceability of the shelves 9, 9 transversely to the transport direction, the width of the collection compartments a, b, c, d, e are adapted to the format of the goods G to be collected. Upstream of the shared collection compartments, in this embodiment of the collection device, as shown in FIG. 5, expediently two separate transport elements 6, 6 are provided, which are arranged transversely to the conveying direction at a distance from each other. Accordingly, two separate Stapelübernahmeeinrichtungen 4, 4 are provided downstream of the shared collection compartments, which are arranged transversely to the conveying direction at a distance from each other.
    The invention is not limited to the embodiments illustrated here in the drawings. Instead of the pivotability of the feed device 5 and in particular the pivotability of the transport element 6 relative to the stationary collecting compartments a, b, c, d, e, it is also possible to move the feed device 5 and in particular its transport element 6 in the vertical direction relative to the collecting compartments a, b, c, d, e. In this embodiment of the device according to the invention, the feed device 5 and in particular its transport element 6 in the manner of a lift in the vertical direction between the lowest collection compartment a and the top collecting tray e are moved to allow storage of goods in any collection compartments and in any order. Alternatively, it is also possible to form the supply device 5 and in particular its transport element 6 stationary and form the collecting compartments, again in the manner of a lift, movable in the vertical direction.
    Instead of the conveyor 3 described here in detail with the synchronously movable conveying elements 3a, 3b, other conveyors may be provided for the removal of the goods from the collecting compartments, such. powered rollers or belts. These are synchronously driven for the simultaneous removal of all goods from the filled collection compartments, so that all goods can be driven out of the collection compartments at the same time.
    Unlike shown in Figs. 6 and 7, the collection compartments may also have continuous shelves 9. For engaging the conveying elements 3 a, 3 b (in particular their slide 3) and the stop elements 2 (in particular their stopper 2) can be provided in the longitudinal direction (conveying direction) of the shelves 9 extending slots.
    Furthermore, it is possible to arrange several collection devices of the type described above conveying direction one behind the other. On the one hand, this makes it possible to collect large stacks with a large number of goods, since partial stacks can already be produced in a first collecting device, which are subsequently stored in a collecting compartment of the downstream second collecting device and combined with other goods or partial product stacks to form a larger stack can. On the other hand, this can increase the total number of collection compartments, without the device receives too high a height. Appropriately, the supply device of the second collection device directly adjoins the stack transfer device of the first collection device downstream, etc. However, it is also possible to arrange further processing stations between successive collection devices.
