Description

METHOD AND DEVICE FOR COLLECTING

FLAT OBJECTS, AND DELIVERY UNIT

The invention is in the field of conveyor technology and relates to an apparatus and a method for collecting and assembling flat objects into a unit which is to be supplied for further processing. The invention relates to a device and a method according to the preamble of claims 1 and 10.

STATE OF THE ART

Devices for collating printed products and creating shipping stacks are known in the art. For example, WO 2010/051651 and EP 2 107 023 describe a device and a method for collating printed products and for conveying the collated printed products further as a stack. For this purpose, the device has a plurality of receiving units, which are movable in a conveying direction along a closed conveying path defined by a conveying member. Furthermore, the device also comprises a plurality of support elements, which define at least in a collation area of the conveyor track an inclined in the conveying direction support surface on which the objects can be stored.

The device is intended for the collection of non-individualized printed matter, such as promotional material, magazines, brochures and newspapers. laid, which are collected in collections units to collections. The shipping stacks formed in this way are then welded into a plastic film and addressed for shipping. The collections wrapped in the plastic film form addressed shipping units, which are handed out to a delivery service. The address is on the outside of the plastic film attached.

Since the collected printed products are not individualized, it does not matter what specific copy of a particular type of printed products z. B. is supplied from a memory of a receiving unit. It is only important that a copy of a particular type of printed matter be delivered to the pick-up units.

In the field of postal services, however, the processing of individualized flat objects, such as letter mail, is known. The individualization is characterized in that each supplied item is provided with a recipient address or an address code from which the recipient address can be determined. It is known to sort the addressed items by recipient address and to produce delivery units or shipping stacks of addressed items, such as mail. Objects with the same recipient address are each assigned to a common delivery unit. However, the apparatus and methods for creating such delivery units are often complex and cumbersome in operation. As part of the letter processing, there is an increasing need to supplement the sent to a recipient mail with non-individualized supplements, such as advertising supplements. In other words, the shipping piles assembled for the recipient should be supplemented with non-individualized supplements, in particular advertising supplements, in addition to the letter. This advertising supplements can also be sent to recipients, which by appropriate instructions to Mailboxes or phone books do not want unaddressed advertising, it is advantageous that the shipping stack can be addressed as such. For this, however, the shipping stack must be surrounded by an addressable shell. DE 37 31 589 describes a method and an apparatus for sorting of mail and for summarizing derselbigen in sorted form. This is done by separating the postal items and then depositing the separated postal items in an intermediate conveyor. The postal items sorted in this way are fed by means of delivery units to collection containers with a target. However, the device and the associated method are extremely complex.

EP 0 710 930 describes a mail processing system with a mailpiece authorization which allows the identification of the mail pieces. However, the document does not describe a method of creating delivery units from multiple flat items.

It is therefore an object of the present invention to propose a device and a method for collecting and assembling flat objects, which allows several objects to be combined into units and further processed, which objects may contain identification information such as recipient addresses, according to which the units are composed - should be set.

A first sub-task of the invention is to propose an apparatus and a method which allow to combine a plurality of flat objects into units, wherein the units should be deliverable for further processing. The device and the method according to the first subtask are also intended to provide the opportunity to require the units in a scale flow, without the division in units canceled and merge the objects together to form a continuous flow of product.

The formation of these units should, however, manage with the least possible effort and low costs and with the least possible retrofitting for existing facilities. A second sub-task consists in proposing a device and a method by means of which individualized objects can be grouped into units with similar individualization features and further processed. In particular, the invention should make it possible to supply the units produced for further processing.

The solution of the two subtasks includes two objects, each representing an independent invention. The first aspect of the invention represents the solution of the first subtask, while the second aspect of the invention relates to the solution of the second subtask. However, the combination of both aspects of the invention leads to a preferred embodiment of both inventions, for which reason both aspects of the invention are described below in the present description.

The first aspect of the invention deals with the collection of flat objects into units in such a way that they remain distinguishable or distinguishable from one another in the subsequent further processing.

The second aspect of the invention, claimed in the present application, is concerned with the grouping of individualized items into units having similar individualization features. The subject of the second aspect of the invention second subtask is solved by the features of independent claims 1 and 10. Further preferred embodiments and further developments of the invention will become apparent from the dependent claims. Characteristics of the method claims are analogously combined with the device claims and vice versa. At this point it should also be emphasized that features disclosed in connection with the first aspect of the invention can be combined with features of the second aspect of the invention.

The collection of flat objects means the formation of collections from a plurality of objects, which are to be supplied as a unit to a further processing. The collections can be formed by collating objects into stacks or by nesting objects or by a combination of the two aforementioned processes.

The unit is preferably a delivery unit. Such a delivery unit is characterized in that the objects contained therein are delivered to a common recipient address. The individualization features of the flat objects correspond to identification information such as recipient address or an address code from which a recipient address can be derived.

The delivery unit includes at least a first flat object and at least one second flat object provided with an identification information, and a flat, flexible enclosing unit which contains two enclosing sections which are bounded along a bending line and form a receiving pocket. The items are combined in the Aufhahmetasche the Umfassungsseinheit to a collection.

The collection preferably contains at least one article provided with an identification information. According to a development of the invention, the enclosing unit may also contain identification information. This can be printed outside on the Umfassungsseinheit. With regard to content, this identification information can correspond to the identification information of an article of the collection provided with identification information.

The enclosing unit may further comprise a viewing window through which the identification information applied to an article of the collection or to an information carrier provided separately and inserted in the receiving pocket is visible. The information carrier may be a printed cover sheet.

The viewing window may be formed by a recess in a peripheral portion of the enclosure unit. This recess can be covered by a transparent foil.

Furthermore, it is also possible for the enclosing unit to be transparent or at least partly transparent to the above-mentioned purpose. The collecting can z. B. represent a stacking of objects or insertion of objects in a recording. In this case, a group of flat objects each forms a loose stack of objects lying horizontally on one another or vertically next to one another or in an inclined arrangement of adjacent ones. The objects lie in each case with their surface side to each other. The term "stack" is to be interpreted accordingly in this aspect. When flat objects are combined into a loose stack, this is called a collection.

The invention is in particular a device for collecting flat objects and for conveying the collected objects as a unit based. For this purpose, the device contains a plurality of receiving units arranged one behind the other, which are moved in a conveying direction along a closed conveying path defined by a conveying member. The receiving units are each guided through a collecting line along which the receiving units are successively supplied with articles via transfer stations of a transfer device. The receiving units form at least along the collection path from a support surface on which the objects are stored. The device may include means for creating delivery units, which are designed so that the delivery units can be supplied to the receiving units via at least one transfer device with at least one transfer station. The creation of the delivery units can take place in the at least one transfer device or in a device upstream of the transfer device.

The flat objects can be printed products, such as newspapers, magazines, brochures, advertising supplements, leaflets or flyers, or additional articles, also called add-ons. Additional articles are in particular samples, such as CD's, DVD's, teabags, flags, T-shirts or foiled products or gimmicks. The additional articles may be attached to printed products. The flat objects can be individualized and provided with identification information, such as address or address code. The flat objects can not be individualized. The flat objects can be flexible or rigid. The flat objects may also include letters, which are provided with an identification information, such as address or address code. Especially in connection with the second subject of the invention, the merging of addressed mail to delivery units plays a central role. A mixed collection of individualized and non-individualized flat objects into units is also possible. The receiving units form for holding and supporting the collected objects in each case preferably two mutually opposite support elements, which form a receiving space for receiving the flat objects. The support elements can be connected to each other or not connected to each other.

The receiving unit preferably forms a bearing surface for the flat objects along the collecting route. The bearing surface is preferably inclined along the collecting route in the conveying direction. The inclination of the support surface is preferably such that the objects are aligned by gravity on a stop described below. The support surface is preferably formed by a support element, in particular by a lower support element. The inclination is z. B. at least 10 ° (angular degree) and a maximum of 60 °. The inclination is in particular 20-30 °. The receiving units can be designed as Aufhahmetchen, Aufhahmezellen, gripper or carriage.

The receiving units can, for. B. part of a cellular wheel or a plug-in drum, which is rotatably driven about its axis of rotation. The cellular wheel or the insertion drum has radially arranged around its axis of rotation and extending in the axial direction receiving cells each having a radially outwardly arranged receiving opening. The receiving cells correspond to the receiving units. The support elements of the receiving cells can z. B. be formed by two relatively movable cell walls.

The cell wheel or the insertion drum comprises transport means by means of which the content of the receiving cells can be displaced in the axial direction.

The Umfassungsseinheiten arranged in the receiving cells are on the one hand by the rotation of the cell wheel or the insertion drum and on the other hand moves the transport in the receiving cells in the axial direction, resulting in a spiral path of movement.

In the axial direction along the cell wheel or the insertion drum transfer stations are arranged in the region of the outer circumference of the cell wheel and the insertion drum, about which objects are supplied to the enclosing units and inserted into this.

The enclosing units are guided past the transfer stations by passing through the spiral track described above and thereby displaced in the axial direction of the cell wheel or the insertion drum.

Devices with cell wheels of the aforementioned type are shown for example in WO 2009/043358, in particular in Figures 1, 2, 5 and 6, and in EP-B-1 090 867, in particular in Figures 1 and 2, and described.

According to a preferred embodiment of the device, the receiving units include grippers, each with a first and second gripper arms for clamping holding the units after completion of the collecting process. The gripper legs are for this purpose relative to each other between an open position, in which a receiving space is formed, and a closed position, in which the unit is clamped, movable. The gripper legs can now be designed as support elements themselves. For this purpose, the grippers preferably have an extended, lower gripper limb, which forms the (inclined) support surface for the objects. The grippers are preferably pivotable relative to the conveyor track, with a pivot axis transverse to the conveying direction.

It is also possible that the support element of the grippers of the receiving units are independent elements which z. B. are guided by means of an independent Stützelemente- conveyor along its own conveyor track, and along which the collection line parallel to the grippers are required. Such a solution is z. As disclosed in WO 2010/051651.

The Aumahmeeinheiten and in particular the associated gripper form at least along the collection line a stop for the arranged in the receiving space, in particular resting on the support surface objects. If grippers are provided, then the stop is preferably formed by the connecting region between the two gripper limbs. The conveyor track, along which the receiving units, and in particular the grippers, are guided preferably comprises two superimposed track sections, which are interconnected by arcuate, in particular circular arc-shaped transition sections. The collection line is formed here in the upper track section. The collecting section and preferably the upper track section preferably run linearly. They are particularly preferably formed horizontally. The lower and upper web sections furthermore preferably run parallel to one another. The receiving units, in particular their grippers, advantageously run in the lower track section through 180 ° (degrees of angle) turned to the opposite upper track section.

Along the collecting route, at least one, preferably a plurality of transfer stations arranged one behind the other, connect to a transfer device, via which individual or a group of objects are transferred to the receiving units conveyed past them. The transfer of the objects preferably takes place during the movement of the receiving units. The movement is preferably at a continuous rate. The transfer device with the at least one transfer station is in each case part of a delivery device, via which articles from a store or a conveying device are fed to the receiving units. The transfer stations can be designed as investors, by means of which the objects z. B. in a curved path the receiving units or the gripper mouth of the gripper are supplied. The objects can z. B. by means of a transfer conveyor belt as part of the transfer station to the receiving units. The objects or the group of objects intended for a specific pickup unit are supplied cyclically to the pickup units, the clock of the transfer stations being synchronized with the clock of the pickup units passing them. The objects or groups of objects are z. B. on the transfer belt one behind the other, but spaced from each supplied to Aumahmeeinheiten. Are z. B. for a receiving unit no objects provided for the transfer, a gap between the objects is introduced on the transfer conveyor belt.

The device preferably also comprises a transfer device, at which the units are transferred from the receiving units to a removal device. The removal device is preferably a belt conveyor. The units are preferably individually and spaced apart or deposited as a scale flow on the belt conveyor and further promoted. The units are preferably stored with the leading collar on the belt conveyor. Contain the Aufhahmeeinheiten gripper, the units are held by the grippers fed to the transfer device and passed under opening the gripper the belt conveyor or stored on this. The transfer device is preferably arranged in the region of an arcuate transition section and / or in the lower track section.

The device for collecting objects or the removal device preferably also comprises a printing device, on which units of flat objects, in particular delivery units, can be printed with identification information, such as address, address code and / or delivery area. The printing device preferably contains an addressing station or consists of a such. The printing device may also include a printing station for printing units with advertising messages or a logo. The advertising messages may include multi-color and / or three-dimensional representations. The printing device may comprise one or more printing stations arranged one behind the other, one of the stations being an addressing station. The printing is preferably carried out on the enclosing unit, and in particular on one of the enclosing sections. For this purpose, z. B. an ink jet method can be used.

The printing device is preferably arranged at the end of the collecting section. In principle, the printing device can also be placed elsewhere in the device. In particular, the sheets can also be printed or addressed to a removal device before the collection line or after transfer of the units. Accordingly, the printing device is arranged in front of the collection line or in a subsequent conveying device.

The device according to the invention also comprises a control device which controls the delivery and delivery of the flat objects to the receiving units, the movement of the receiving units along their orbit and the delivery of the units to a removal device. The control device is connected to the corresponding devices of the device via bidirectional data lines.

The first subject of the invention now relates to a method for collecting flat objects and for conveying the collected objects by means of receiving units, wherein the receiving units for holding and supporting the collected objects each have two mutually opposite support elements, which form a receiving space.

The method according to the invention is characterized by the following method steps: - Providing along a bending line partially weakened flat, flexible Umfassungsseinheit, and

Bending the flat enclosing unit along the bending line to form two enclosing sections delimited by the bending line; imports of the curved enclosing unit into the retainer ring between the supporting elements;

- Holding the Umfassungsabschnitte the Umfassungsseinheit in Aufhahrneraurn to the adjacent support elements to form a Aufhahmetasche;

- Feeds at least one object in the mitbewegte Aufhahmetasche the curved enclosure unit;

- Towards the two enclosing sections.

When inserting the bent enclosing unit into the receiving space between the support elements, a restoring force in the direction of a planar position of the enclosing unit preferably acts on the curved enclosing unit in a non-weakened region along the bending line.

Holding the Umfassungsabschnitte in the receiving space on the adjacent support elements is preferably done by the wifken- on the Umfassungsabschnitte restoring force. The enclosing sections are pressed against the adjacent support elements. That is, the bent enveloping unit is held in the receiving space by the pressing force.

The enclosing unit is preferably closed after the joining sections have been moved towards one another. For this purpose, the enclosing sections, in particular in at least one edge region, connected to each other. The connection can take place by means of an adhesive which connects the enclosing sections to one another. The compound may be soluble or insoluble. The adhesive can connect the enclosing sections to one another at least over part of the area in an edge area. The enclosing sections can also be connected to one another in at least part of the area over the adhesive in a plurality of edge areas. Thus, the Umfassungsabschnitte at least part of the area in the edge regions of three product edges, which do not correspond to the federal government, be connected to each other by means of an adhesive.

The enclosing unit can, for. B. by means of a two Umfassungsabschnitte interconnecting, flat adhesive element, such as adhesive tape to be closed. Furthermore, an adhesive or adhesive material can also be applied to a surface region of a surrounding section, which connects the two surrounding sections in said surface region when the same are brought together.

The enclosure unit is flexible and flexible. It preferably contains pulp fibers, such as cellulose fibers, which are particularly preferably anisotropically oriented. The enclosing unit can be a sheet with a single-layer or multi-layered or layered construction. Preferably, at least one layer or layer of paper, cardboard or paperboard. Several layers can z. B. glued together. Other layers can also be made of metal or plastic. The plastic layer can be added to the layer composite by means of extrusion, lamination or lacquering. The flat, flexible enclosing unit may also consist of a plastic, in particular a plastic film. The enclosing unit can be a single or multi-leaf product. This multi-leaved product may be bound, stapled or glued. The enclosure unit can have different surface dimensions and geometries and z. B. polygonal, round or combined forms. The enclosing unit is preferably designed rechteckfbrmig. The enclosing unit may also be in the form of a strip. The enclosing sections may be smaller in area than the objects collected therein. The enclosing unit may also contain reinforcing structures, such as wall thickenings, which z. B. increase the restoring force in the direction of a flat position of the enclosing unit.

The enclosing unit, which is partially weakened along the bending line, forms an open envelope or jacket for receiving the flat objects. The enclosing unit is preferably open on three sides. A rectangular enclosing unit has, for example, a bending line and three edges along which the enclosing unit is open. The enclosing unit forms a stop in the region and along the bending line for the objects pushed into the receiving pocket of the enclosing unit. The enclosing unit preferably has only one bend line or only one or a plurality of fold lines arranged along a single bend line. The enclosing unit preferably consists of a single sheet.

The enclosing unit is preferably an arc, wherein the enclosing sections correspond to the curved sections and the enclosing edges correspond to the curved edges. The sheets are made of paper with a basis weight of z. B. 20 g / m to 200 g / m, in particular of z. B. 40 g / m to 120 g / m. However, the grammages can be higher. The bow can z. B. also be made of cardboard. As is usual with paper, the sheets have a fiber distribution with anisotropic fiber orientation. The enclosing unit preferably consists of a single sheet.

The weakening along the bend line may be in the form of a groove, a fold, a cut or a perforation. The weakening may also be due to wetting along the bending line, z. B. by a line wetting, be formed. The weakening is preferably designed as a weakening line. Around Weakening line is the restoring force of the bow canceled or at least reduced. The weakening line is preferably a fold line. A cut or a perforation can be made by means of a cutting or punching tool. In order to ensure a sufficient restoring force of the enclosing sections, preferably 90% of the bending line or less remain unimpaired. Furthermore, preferably at least 15% of the bendline is not weakened. However, this value also depends on the material properties, such as fiber content, fiber orientation, basis weight or thickness of the sheets or possible coatings. Consequently, the restoring force can be adjusted via the height of the ratio of the total length B of the one or all weakening lines along the bending line to the total length A of the bending line. The ratio B: A can be, for example, 0.1 to 0.7 and is always less than 1. The smaller the ratio, the greater the restoring force of the enclosing sections. For this purpose, the device preferably contains an enclosing unit feed device for feeding a enclosing unit, which is partially weakened along the bending line, and for transferring the enclosing unit into the receiving space of the receiving unit. The wrapping unit supply device is preferably designed to be able to insert the wrapping unit partially weakened along the bending line in a bent state into the receiving space, the enclosing unit pressing against the supporting elements with its enclosing sections, which are bending sections, due to the restoring force of the support elements is held. The enclosing unit supply device can be designed as a feeder, by means of which the enclosing units z. B. in an arcuate path the receiving units or the gripper mouth of the gripper are supplied.

The restoring force of the enclosing unit causes spreading of the enclosing portions of the enclosing unit, wherein the Umfassungsabschnitte invest in the support elements. The spreading process is thus by the support elements limited. The contact pressure of the Urnfassungsabschnitte to the support elements causes a relatively high static friction, so that can not move the enclosing unit without a minimal effort in the receiving unit. In a preferred embodiment of the invention, a plurality of objects are deposited via one or more transfer stations to form a (small) stack in the receiving pockets. The receiving units are for this purpose moved in the conveying direction along the closed conveyor track. The articles are preferably introduced transversely to or opposite to the direction of movement of the receiving units into the receiving pockets formed in the receiving units along the collecting route. For this purpose, the objects are preferably deposited on a surrounding portion of the bent enveloping unit in the receiving pocket. If the receiving units include grippers, the gripper legs preferably form the supporting elements. According to this embodiment, the gripper legs in the open position form the receiving space, in which the enclosing unit is held to form the receiving pocket. In the closed position of the gripper arms, the enclosing sections are guided towards one another, wherein the gripper legs clamp the collected objects together with the enclosing unit.

In a development of the invention, the method also comprises the creation of at least one line of weakness along a bending line on the enclosing unit. According to the invention, the at least one weakening line is shorter than the bending line and only extends over a part of the bending line. If the weakening line is a fold line, then the folding operation is carried out by means of a folding device. The folding device may be part of the device for collecting flat objects. The folding device is coupled to, for example, the envelope unit feeder. For example, units fed to the folding device, partially folded in the folding device and fed via the enclosing unit supply device to the receiving units at the beginning of the collection line. The processing of the enclosing units in the folding device is preferably done in-line and clock-related with the movement of the receiving units.

The folding device for creating the Teilfalzes can work, for example, according to the pocket folding principle, which is known from the prior art. The folding device contains for this purpose a lateral pocket stop for the Umfassungsungs- unit and two rotating folding rollers, between the folding rollers an upsetting space is formed, in which the abutting stopper at the abutment is compressed and pulled to form a fold break between the folding rollers. In order to form a partial fold along the bending line, the folding rollers now do not extend in the direction of their axes of rotation over the entire length of the bending line but only over that section of the bending line in which a fold break is to be produced.

The folding device can also operate on the Schwertfalzprinzip, which is also known from the prior art. The folding device contains here in addition to the two rotating folding rollers nor a sword, which pushes the enclosing unit along a bending line between the folding rollers. The sword virtually replaces the compression of the Umfassungsseinheit causing pocket stop. In order to form a partial fold along the bending line, the folding rollers now do not extend in the direction of their axes of rotation over the entire length of the bending line but only over that section of the bending line in which a fold break is to be produced. Furthermore, the sword can also extend only over that section along the bending line, in which a fold break is to be generated. The folding is basically preferably transversely to the conveying direction. The folding device may further include a creasing unit in which the enclosing units are grooved along the fold line to be produced before folding. The creasing is preferably transverse to the conveying direction. The Rill unit is designed accordingly. The individual enclosing unit is therefore grooved only over that section along the bending line, in which subsequently also a fold line is created. Correspondingly, the scoring tool, such as scoring blades, also extends only over that part of the way along the bending line in which a fold line is subsequently produced. Folding means in paper processing the production of a sharp bending edge, also called fold line or fold break with the aid of a tool or a machine. Folding causes breakage of fibers crossing the fold line so that layers or plies containing pulp fibers, e.g. As paper, along the fold line the residual stress, which causes a restoring force when bending, completely or at least partially loses.

The groove, in turn, means in paper processing the indentation of a fracture line around the folding of a pulp fiber containing layer or layer, e.g. B. paper, simplify. The grooves cause a liruene-like substance displacement or a pre-breaking of the fibers. This happens z. B. by means of pressing tools to create a bending capacity for the material.

As already mentioned, the single enclosing unit has a bending line extending between two edges. Bending line means that the transfer unit is bent along this line to form two enclosing sections, without, however, necessarily producing a line of weakness. The bending line now expediently contains a plurality of partial sections, wherein at least one partial section forms a weakening line and at least one partial section does not form a tamping line. Change preferentially sections with weakening line and sections without weakening line along the bending line each from.

According to a first embodiment of an enclosing unit, a middle section of the bending line has a weakening line, while the two side sections extending toward the enclosing edges have no line of weakness.

According to a second embodiment of an arc, the two lateral sections extending towards the peripheral edges have a weakening line, while a middle segment of the bending line lying between the lateral partial sections has no line of weakness.

In a further development of the invention, the method also includes the closing of the gripper after completion of the collecting process of objects and the gripping of the curved enclosing unit with the objects collected in these by the gripper arms in the manner described above. The units held by the gripper units are preferred in this way weitergefbrdert along the conveyor track before this z. B. be transferred to a transfer device of a removal device.

The opening and closing of the gripper along the orbit is done in a known manner, for example via a Kulissenfuhrung, which cooperates with actuating means, such as control rollers, with the grippers.

In a development of the method according to the invention, the enclosing unit, together with the objects held in it, is transferred as a unit via a transfer device to a removal device. According to a possible embodiment of the method according to the invention, the enclosing unit is immediately after completion of the unit, for. B. at the end of the collection line, or indirectly following the collection process, for. B. in a removal device, while forming a continuous fold line along the bending line completely folded. For this purpose, a corresponding folding device can be provided. In principle, the gripper can also be configured in such a way that the continuous fold line and thus the complete folding are carried out simultaneously with the closing of the gripper. In addition, a double belt conveyor can be provided. The finished unit can be passed between the two conveyor belts of the double belt conveyor, wherein the enveloping unit is completely folded by the pressing force of the conveyor belts. The double belt conveyor z. B. be a way conveyor following the collection route.

The second aspect of the invention now relates to a device and a method for assembling presorted mail to form so-called delivery units, for which purpose the device described above for collecting objects is used. The above units correspond here to the aforementioned delivery units.

The second invention is characterized in that the device for collecting objects contains a feeder device for feeding or supplying individualized articles provided with identification information to the receiving units.

The feeder device further includes at least one storage unit for providing the individualized objects in stack formation, in particular as a rod, as well as a separating unit for separating the individualized objects. In addition, the feeder device contains a checking unit for checking the identity information on the objects and at least one transfer device with at least one transfer station, via which the individualized objects are transferred to the receiving units.

The checking unit can also be designed to check the separation of the objects. In this way, malfunctions, such as the simultaneous removal of multiple items from the at least one storage unit, can be determined. The determined information is processed accordingly in a control device.

The checking unit can be arranged at the separating unit. However, the checking unit can also be arranged at a post-processing position in the feed device.

The term "individualized" should not be confused with the term "isolated". Individualized objects contain an identification information, by means of which they differ from other, similar objects and, for. B. can be assigned to a recipient address. The recipient address may concern a household, a person, a company or a building. Isolated objects, however, are individually present objects.

The associated method is characterized by the following steps: Moving the receiving units in the conveying direction along the collecting path of the closed conveyor track;

Providing grouped, presorted, individualized, i. articles provided with identification information,

- separating individualized objects from the group, Checking an identification information, such as address, of the separated objects,

- moving the articles to a transfer station of a transfer device, and - transferring the articles to the buffer units along the collection path of the transport path.

The grouped items can z. B. in rod or stack formation. The checking unit checks the identification information acquired on the item. For this purpose, the checking unit is connected to a control device which, on the basis of the result of the transmission, correctly assigns the objects to the subsequent further processing units via an allocation device having at least one allocation unit. The purpose of the check is to ensure that objects with matching identification information are transferred to a common reception unit and objects with different identification information are transmitted to different reception units.

According to a preferred embodiment, the individualized objects in the stack formation are already presorted according to their identification information, whereby objects with matching identification information are arranged directly following one another. The Übei ruiungseinheit now compares the detected identification information stored in a data storage identification information, which correspond to the presorting of the objects. That the order of the presorted objects is also stored in the data memory. In this way, it should be checked whether the objects actually exist in the presorted order or deviate from it.

The individualized objects are now conveyed via an allocation device with at least one allocation unit either indirectly, in particular via an intermediate device. storage system, or assigned directly to a transfer station, with objects with matching identification information, such as address or address codes, are stored in a common receiving unit. According to a first embodiment of the second invention, the feeder device for feeding individualized objects comprises a storage unit, a transfer device with a plurality of transfer stations and an allocation device with an allocation unit. The objects are assigned to the individual transfer stations by means of the metering unit and transferred from these to the imme units. In this case, the allocation unit feeds articles with the same address to successive transfer stations via which the objects which are supplied to the receiving unit passing the transfer stations are supplied. Objects with the same address are thereby transferred via a plurality of transfer stations arranged along the collection route to a common receiving unit.

According to a second embodiment of the second invention, the feeder device for feeding individualized objects comprises a memory unit, a buffer system with a plurality of latches for a respective group of objects. Furthermore, the feeder device also includes an allocation device with an allocation unit and a transfer device with at least one, preferably exactly one transfer station. The objects are allocated via the allocation unit to the latches of the intermediate storage system and optionally grouped there into groups of several objects. A group formed in a buffer includes items each having the same identification information.

The individual groups are then transferred from the latches via the transfer station the receiving units, wherein a group of objects is transferred to a common receiving unit. Is there too an identification information only one object, so this item is individually stored in a cache. That is, a group can contain one or more items. The buffer system represents a kind of sorting memory, in which groups of individualized objects are formed and buffered, which will be delivered to recording units in a subsequent step. Therefore, it is basically sufficient if said feeder comprises only a single transfer station, which is sequentially loaded with groups of articles from the latches.

According to a third embodiment of the second invention, the feeder for feeding individualized items includes a plurality of storage units, e.g. B. two memory units, as well as analogous to the second embodiment, a cache system with a plurality of latches for each group of objects.

Furthermore, the feeder device comprises an allocation device with a plurality of metering units, which can be moved one behind the other via a conveyor organ along a direction of movement about an orbit. The metering units are conveyed along their conveyor track past the storage units. From the storage units, the previously separated letters are handed over to the allocating units conveyed by them.

In addition, the feeder likewise contains, analogously to the second embodiment, a transfer device with at least one, preferably exactly one, transfer station.

The items in the dispatch units are allocated by the dispatch units to the buffers of the cache system and transferred to them. Where appropriate, groups of several counterparts created. A group formed in a buffer includes items each having the same identification information.

The individual groups of objects are subsequently transferred from the intermediate stores via the transfer station and from there to the pick-up units, with a group of objects being transferred to a common pick-up unit.

If there is only one object for an identification information, this object is stored individually in a buffer. That is, a group can contain one or more items.

The buffer system represents a kind of sorting memory, in which groups of individualized objects are formed and buffered, which will be delivered to receiving units in a subsequent step. Therefore, it is basically sufficient if said feeder comprises only a single transfer station, which is sequentially loaded with groups of articles from the latches. The allocation units according to the three embodiments each cooperate preferably with a switch system or contain such. The objects can be assigned to the corresponding buffers of the intermediate storage system or the corresponding transfer stations of the transfer device via the switch system.

According to the third embodiment, however, for the purpose of transferring the objects to a buffer store or to a transfer station, the metering units can also be conveyed along their orbit past the buffer stores or the transfer stations. There are means of transferring the objects of provided to the allocation units to the latches or the transfer stations. A turnout system is not necessary according to this variant.

Of course, advertising supplements can be customized via a corresponding printing device before the collection route, z. B. addressed, and supplied as individualized items the receiving units. Again, the control device provides a clock-related, in particular isochronous processing of the objects that the individualized advertising supplements are assigned to the correct receiving units.

With the device according to the invention and the associated method, individualized objects, such as addressed letters, can be processed and combined with non-individualized objects, such as advertising inserts, to form individualized delivery units. This distinguishes the present device and method from known devices and methods in which non-individualized items, such as newspapers, magazines, or advertising inserts, are collected into collections, packaged, and individualized at the end by printing an address on the wrapping.

Basically, the same parts are provided with the same reference numerals in the figures. In the following figures, the enclosing unit is shown and described as a bow. However, this should not be construed as limiting the embodiments to enclosing units of sheets. Furthermore, in the following embodiments, sheets with fold lines are described. Of course, as described above, instead of fold lines, weakening lines may be provided quite generally.

WAYS FOR CARRYING OUT THE INVENTION

FIG. 1 shows an unfolded, planar sheet 1.1, which forms the starting material to form a partially folded, three-sided open envelope for receiving flat objects. The sheet 1.1 has a, from a first to an opposite, second edge of the arc extending bending line 2, along which the sheet 1.1 is bent in a later process step and partially folded.

FIGS. 2 and 3 each show a partially folded sheet 1.2 and 1.3 along the bending line 2. The bending line 2 divides the sheet 1.2 in two arc sections 8a, 8b.

According to the embodiment according to FIG. 2, a fold line 5, which is shorter than the bending line 2, is arranged along a middle section of the bending line 2. It is flanked by two non-folded sections 4a, 4b arranged laterally along the bending line 2, which lead to the sheet edges to lead.

According to the embodiment according to FIG. 3, the bending line 2 has two laterally arranged fold lines 6a, 6b, which lead to the sheet edges. The fold lines 6a, 6b, close along the bending line 2 a non-folded, middle section 7 a. The sheet according to FIGS. 2 and 3 now has along its bending line 2, at least in the region of the non-folded middle section 7, an internal stress which exerts on the sheet sections 8a, 8b laterally of the bending line 2 a restoring force from a bent to a planar position.

FIG. 4 shows a limited section of a device 10 for collecting articles from the region along the collection path S. The device 10 has receiving units 11 in the form of grippers. The grippers 11 are spaced apart in the conveying direction F attached to a conveyor chain 13. The conveyor chain 13 is guided with the grippers 1 1 along a guide device 14. The grippers 11 have an upper, first gripper limb 12a and a lower, second gripper limb 12b movably arranged relative to the first gripper limb 12a along the collection line S. The second gripper limb 12a is extended relative to the first gripper limb 12a and forms a support surface for the objects 9a, 9b to be collected. The gripper legs 12a, 12b form a gripper jaw, which corresponds to the receiving space for a curved along the bending line 2 and partially folded sheet 1.2, 1.3. On that, the gripper mouth opening opposite side of the gripper 11, a stop 15 is formed in each case.

For the purpose of feeding curved partially folded sheets 1.2 into the gripper jaw of the grippers 11, a sheet feeder 20 is provided. The sheet feed device 20 is designed for the supply of sheets 1.2, in which the fold line 5 is arranged along a middle section 7 of the bending line 2. About the sheet feeding device 20 partially folded sheet 1.2 are now supplied to the grippers 11. The sheet feeder 20 has a spring-loaded feed roller 16 cooperating with a transfer conveyor belt 23, which takes over the partially folded sheets from the folding device and forwards them to a conveyor unit of the sheet feed device 20. The feed roller 16 may be made of foam or contain this to ensure a gentle pressure on the sheet in the region of the central portion in which lies the fold line. The delivery unit comprises a double belt conveyor 21, by means of which the sheets are conveyed to a discharge point. The double belt conveyor 21 is designed so that the curved sheet 1.2 are guided on both curved sections 8a, 8b by a conveyor belt and held in a clamping manner. However, the individually conveyed sheet 1.2 are only in the central portion of the bending line 2, in which the fold line is arranged, in the conveying engagement with the two conveyor belts of the belt conveyor 21. In the region of the lateral sections in which the unfolded sections 4a, 4b of the bending line. 2 Although the sheet 1.2 is guided, it is not covered by the conveyor belts, so that in this area no fold line is formed by the pressing force of the belt conveyor 21.

Basically, in the entire sheet feeding device 20, the sheet 1.2 only with those sections in the conveying engagement with the corresponding Förderorga- NEN, such as belt conveyors arrive, in which the sections of the bending line 2 lie with a fold line. In this context, conveying engagement means, in particular, a contact pressure exerted on the sheet for producing a frictional contact with the sheet for the purpose of transmitting a moment of movement, e.g. B. from a conveyor belt or conveyor rollers on the bow.

In the present sheet feeding device, the non-conveyed side portions of the bent sheet 1.2 are supported and guided with the unfolded sections by a surface guide member 22 in the form of a guide plate along the conveying direction Fb. The sheets 1.2 are delivered at a transfer point of the sheet feeder 20 (not shown).

The single sheet 1.2 is inserted in the transfer in the bent state with the bending line 2 ahead in the gripper mouth of the gripper 11. The bending line 2 is thereby pushed into the gripper mouth up to the stop 15. By the force exerted by the unfolded sections of the bending line 2 on the arc sections 8a, 8b restoring force the arc sections 8a, 8b spread apart. The sheet sections 8a, 8b are applied to the gripper legs 12a, 12b while exerting a pressing force in the gripper jaw. The pressure force generates a frictional connection, so that the sheet 1.2 is held in the gripper jaw and is secured against lateral displacement. The sheet 1.2 is at least partially opened according to the Öffhungsweite of the gripper jaw and forms a receiving pocket for the subsequently collected flat objects 9a, 9b. Following the collection of the flat objects 9a, 9b, the grippers are closed for further promotion. In this process, the two arc sections 8a, 8b are guided to each other. The gripper arms 12a, 12b hold the collected objects 9a, 9b between the bow sections 8a, 8b in a clamping manner. The closed bow 1.2 with the flat collected in it Articles 9a, 9b are transferred by the grippers 11 to a removal device for further processing (not shown).

FIG. 6 shows a possible embodiment of a folding device for producing partially folded sheets 1.2. The folding device is designed as a creasing folding device 30. The creasing-folding device 30 includes a feed section via which in a feed direction Fa by means of a conveyor belt 31 individual flat sheets 1.1 are fed. The sheets are aligned on the feed path along a Richtnockenbandes by leading cam 34 of the slower running Richtnockenbandes come to rest on the leading edges of the sheet 1.1 and so evenly spaced and align the sheet 1.1 apart.

The creasing folding device 30 includes a RiU folding unit 32 in which the single sheet 1.1 is first grooved along a bending line 2 along that or that sub-section (s) in which a folding line 5 is subsequently applied. The creasing unit is designed so that it acts only on the section (s) of the bending line 2 in which or which a folding line 5 is to be created. Following the groove, the sheet 1.2 is partially folded in a Taschenfalzaggregat, wherein the Taschenfalzaggregat designed so that the associated folding rollers acts only on the grooved sections of the bending line and not on the entire bending line 2 of the sheet 1.2. This means, in particular, that the folding rollers do not extend over the entire extent of the bending line 2 but only over one or more partial sections thereof.

After attaching the folding line 5, the sheet 1.2 is released from the creasing-folding device 30 and passed, for example via an above-described sheet feeding device 20 to the receiving units 12. The described creasing device 30 and sheet feeding device 20 are not mandatory features of the device 10 for collecting objects but only preferred embodiments of such devices, with which the inventive device 10 can be supplemented particularly advantageous. The sheets can in fact be folded in other ways and fed to the device 10 in other ways. In particular, the sheets do not need to be in-line, ie to be folded in the production line, but can also be retrieved from the intermediate store already provided with the partial fold. Figures 7, 8 and 10 show now three special embodiments of a device 40.1, 40.2, 40.3 for collecting objects according to the second subject of the invention. The partially folded sheets 1.2, 1.3 as an envelope for collecting flat objects, as described in connection with FIGS. 1 to 5, are particularly suitable for use in the three devices 40.1, 40.2 and 40.3 described below. Furthermore, the creasing folding device 30 according to FIG. 6, the sheet feeding device 20 according to FIG. 5 and the conveying device with grippers 1 1 according to FIG. 4 are also particularly well suited for use in the three devices 40.1, 40.2, 40.3. In the facilities of Figure 7, 8 and 10 is about the preparation of ready to ship delivery units. This is primarily about the processing of mail. The present invention is based on two subtasks. On the one hand, letters with the same address are to be combined into one delivery unit, so that the delivery agent can combine the letters as a single unit and not deliver them individually to the recipient. The delivery unit should also be addressed as a whole. A second sub-task is the delivery units not individualized, z. B. not addressed supplements, such as advertising supplements or additional items to attach. Since the delivery unit, which adresses as well as addressed letter post also ad inserts, is addressed as a whole, advertising can also to those receiving circles who do not want non-individualized advertising.

The tasks are now solved in that letter and non-individualized supplements, which are addressed to a recipient, are loosely collected in a partially folded sheet. The bow forms a kind of envelope, which serves in particular to hold collections together and separate from other collections. The devices 40.1, 40.2, 40.3 according to FIGS. 7, 8 and 10 now have a plurality of receiving units 41 which are movable in a conveying direction Fe along a closed conveying path defined by a conveying member. The receiving units 41 and the conveying member are preferably designed according to the embodiment shown in FIG. The device 40.1, 40.2, 40.3 forms a collecting route S, along which the flat objects 50 are collected.

At the beginning or before the collecting line S, according to the invention, sheets are partially folded according to the invention by means of a creasing and folding apparatus 30 according to FIG. 6 and fed to the receiving units 41 via a sheet feeding device 20 according to the embodiment shown in FIG. The creasing folding device 30, in turn, receives the sheets 1.1 from a sheet buffer store 57, which stores the sheets 1.1 in stack form and delivers them via a separating unit to the supply path of the creasing folding apparatus 30. However, the feeds of the sheet 1.1 and the folding derselbigen and the transfer to the receiving units 41 and the related devices can also be configured differently. In particular, the intermediate memory 57, the creasing device 30, the sheet feeder 20 and the receiving units 41 with the associated conveying member 13, as already mentioned above, be designed differently. The devices 40.1, 40.2 and 40.3 according to FIGS. 7, 8 and 10 furthermore include a feeder device 80 for feeding flat, addressed objects 50 into the receiving pockets of the partially folded sheets 1.2, which are arranged in the receiving units 41. The term "addressed" means in the broadest sense that the objects are provided with identification information, which allow the object to be assigned to a specific recipient address manually or via a data processing device. This can be z. As the address itself or a machine-readable address code. The objects are primarily letters. The term "letter" in the broadest sense means an information carrier packed in an addressed envelope, such as, for example, information written on paper.

The feeder device 80 according to the two embodiments according to FIGS. 7 and 8 comprises a storage unit 48 which provides the letters 50 in stack formation.

The feeder device 80 according to the embodiment of FIG. 10, on the other hand, comprises two storage units 48.1, 48.2, which provide the letters 50a, 50b respectively in stack formation. For example, the two storage units 48.1, 48.2 receive letters 50a, 50b of different format. Thus, for example, a first memory unit 48.1 record small-format letters 50a while the second memory unit 48.2 receives large-size letters 50b.

The letters in the storage units 48, 48.1, 48.2 are each already presorted. In particular, letters with the same recipient address are preferably arranged directly behind one another. Furthermore, the letters are preferably already ordered by delivery area or even by delivery route of a delivery area. Thus, the letters of a delivery area can be arranged one behind the other, so that they can be fed directly after the collection process without further sorting in a transport device, which z. B. for a delivery area assigned to responsible offspring. Preferably, as mentioned, the letters are sorted not only according to delivery area but also according to delivery route, along which the delivery agent who deliver the letters to the recipients. In this context, the device 40.1, 40.2, 40.3 according to the invention comprises an electronic data memory 47, in which the address information of the previously electronically recorded letters is stored. Furthermore, the sorting sequence of the letters stacked in the storage unit 48 is also stored in the electronic data memory 47. The electronic data memory 47 with the address and sorting information is connected to a control device 45. The control device is connected via bidirectional data or control lines 46 to, among other things, the separating unit 49, the transfer stations 55, 55a... 55d, the creasing device 30 of the sheet feeding device 20 and the drive 44 of the receiving units 41.

The data memory 47 may contain further data, so the individual stored address information can be assigned individual information or receiver profiles. Such Empfangerprofile can z. As interests, occupation, hobbies, gender, age or origin of the behind the address information receiver include. Receiver-specific delivery units can now be created via the control device. Thus, the individual delivery units targeted recipient specific items, such as advertising supplements, be added. Furthermore, the sheet can also be specifically printed with advertising messages in addition to the address. So z. B. in the delivery unit of a motorcycle enthusiast targeted advertising for motorcycles or motorcycle events are introduced.

In terms of control technology, the device is set up such that the delivery units in the device according to the invention can be identified by the control device. The creation and promotion of the delivery units in the inventive Setup is therefore clock-controlled. The delivery units are assigned to individual cycles, with the control device always knowing in which cycle a specific delivery unit is currently located. For this purpose, the control device creates, for example, a virtual clock image of the device. This also allows the correct addressing of the sheet so that the address on the sheet matches the address of the sheets being held in the sheet.

The separating unit is preferably controlled or regulated independently of the movement of the receiving units along the collecting line and has z. B. a different clock than the Aufhahmeeinheiten on. Since groups of letters are handed over to the receiving units, the separating device usually has a higher working cycle than the receiving units along the collecting line. The above-mentioned embodiments of the clock-controlled operation of the device generally apply to devices and methods which fall under the present claims, and are not limited to the embodiments shown.

The memory unit 48, 48.1, 48.2 is in each case assigned a separating device 49 and a control unit 51. At the separating device 49, the letters 50 are individually taken from the stack formation and fed to the control unit 51. At the control unit 51, the address of the letters is checked and compared with the information stored in the data memory 47. In particular, it is checked whether the removed letter 50 is actually singulated and is in the correct position in the sorting sequence as stored in the data memory 47. Furthermore, it is also checked whether the detected address matches the stored address data. The control unit 51 may include a camera system which acquires the address data from the letters by means of an imaging method and converts it via corresponding data processing software into digital address information. The control unit 51 does not necessarily have to be arranged in the region of the separating device 49. It can also be located downstream of a processing point, z. B. in the range of the allocation unit 52 may be arranged. According to the embodiment according to FIG. 7, the separated letters 50 are conveyed on to an allocation unit 52 after passing through the control unit 51. The allocation unit 52, which z. B. can be a turnout system or cooperate with such, forwards the letters 50 individual, along the collection line S successively arranged letter transfer stations 55a ... 55d on. At the letter transfer stations 55a... 55d, the letters 50 are transferred to the receiving units 41 by being deposited or inserted in the receiving pockets of the sheets 1.2 located in the receiving units 41. For this purpose, the receiving units 41 are guided along the collecting line S past the letter transfer stations 55a... 55d. The cooperating with the receiving units 41 conveying member is driven by the drive 44, which in turn is controlled by the control device 45.

The device is now controlled via the control device 45 such that letters with the same recipient address of a common receiving unit 41 and letters with different addresses are plugged into different receiving units 41. This happens, for example, in that letters 50 having the same recipient address, which pass directly through the allocation unit 52 according to presorting, are assigned to adjacent letter transfer stations 55a... 55d. A receiving unit guided past the letter transfer stations 55a... 55d now undertakes in sequential order all the letters 50 with the same recipient address from the letter transfer stations 55a... 55d arranged one behind the other and collects them in the receiving pocket of the sheet 1.2 for a particular recipient address a delivery unit with all letters created with the same recipient address. According to the slightly modified embodiment according to FIG. 8, the letters 50 are fed via an allocation unit 52 to a storage system 53 having a plurality of individual intermediate stores 53a... 53d. The device 40.2 is controlled by the control device 45 so that letters 50 with the same recipient address are assigned to a shared buffer memory 53a... 53d and letters 50 having different addresses to different buffer memories 53a... 53d.

The feeder device 80 also also contains a letter transfer station 55. The units of letters with the same recipient address formed in the latches 53a... 53d are in each case forwarded as a group via a switch 54 to the letter transfer station 55 and transferred from there to the receiving units 41 , According to a further embodiment of FIG. 10, the letters 50a, 50b, similar to the exemplary embodiment according to FIG. 8, are supplied via allocation units 52 to a storage system 53 having a plurality of individual latches 53a... 53d. The device 40.3 is controlled via the control device 45 so that letters 50a, 50b with the same ¹ recipient address are assigned to a common intermediate memory 53a ... 53d and letters 50a, 50b with different addresses to different latches 53a ... 53d.

The present device 40.3 or the feeder device 80 now contains an allocation device 59 with a plurality of metering units 52, which can be moved in series about a conveying direction 61 along a movement direction Fz. The conveying device 61 can be, for example, a conveyor chain with which the metering units 52 are connected.

The metering units 52 are guided in their movement along their orbit past the two storage units 48.1, 48.2 and take over from the Memory units 48.1, 48.2 the previously isolated letters 50a, 50b. Each allocation unit 52 takes over from the storage units 48.1, 48.2 each a letter or possibly more letters with the same recipient address. The dispatching units 52 convey the letters 50a, 50b to a delivery point. At the point of delivery, the letters 50a, 50b are transferred from the allocating units 52 to the latches 53a ... 53d. Into the latches 53a ... 53d, units of letters with the same recipient address are assembled. The transfer of the letters 50a, 50b from the allocating units 52 to the latches 53a ... 53d can take place in different ways.

Thus, means may be provided which allow the letters 50a, 50b to be fed from a defined position of the metering units 52 along the orbit from the corresponding latches 53a ... 53d. This type of transfer corresponds to a star-shaped allocation of the letters 50a, 50b from a defined position of the allocation unit 52 to the latches 53a ... 53d. The funds can z. B. include an intermediate conveyor with switch system.

It is also possible for the arbiter units 52 to be routed past the buffer memories 53a... 53d and for the letters 50a, 50b to be passed to the corresponding buffer memories 53a... 53d during the passage.

The arbiter 59 may also perform a buffering function in which the arbiter units 52 buffer the letters 50a, 50b until they are delivered to the latches 53a ... 53d. The more allocation units 52 the allocation device 59 contains, the greater is the buffering effect.

The metering units 52 of the metering device 59 are operated at a higher processing speed than the picking units 41 of the collecting device. That is, with the metering units 52, more product units are processed per time than with the picking units 41. In principle, the device 40.3 can also contain more than two memory units 48.1, 48.2. The allocation device 59 or the number of allocation units 52 contained in it must be adapted accordingly to the number of storage units 48.1, 48.2.

The feeder 80 also includes a letter transfer station 55. The units formed in the latches 53a ... 53d of letters with the same recipient address are each forwarded as a group via a switch 54 to the letter transfer station 55 and from this from the on immeeinheiten 41st to hand over.

Since the units of letters 50, 50a, 50b with the same recipient addresses according to the two embodiments of FIGS. 8 and 10, in contrast to the embodiment according to FIG. 7, are already formed in the temporary storage system 53 and not in the receiving units, according to the present embodiment only transfer station sufficient. The temporary storage system 53 acts as a sorting memory, in which the units of letters are retained until they are available for forwarding to the letter transfer station 55, the control device 45 ensures that only completely created delivery units of letters to the letter Transfer station 55 are forwarded.

As already mentioned, the embodiments according to FIGS. 8 and 10 have the advantage that the feeder device 80 basically has a single letter transfer station 55 or at least substantially less letter transfer station 55, eg. B. with the two, gets along as according to the embodiment of Figure 7 are used. As a result, for example, there is more space for more transfer stations, eg. B. for supplying non-individualized advertising supplements, available. Otherwise, the collection section can be made shorter and the system can be made more compact. Before and / or following the letter transfer stations 55, 55a ... 55d for the mail, as already mentioned, further transfer stations 42a... 42c can be arranged, via which further individualized or non-individualized, ie addressed or non-personalized addressed, flat objects, such as advertising supplements are delivered.

According to the three embodiments according to FIGS. 7, 8 and 10, transfer stations 42a... 42c for advertising inserts are arranged along the collection route S following the letter transfer stations 55, 55a... 55d for addressed letters. After transferring the letters 50, 50a, 50b into the receiving units 41, non-individualized advertising inserts are now introduced into the receiving pockets of the sheets 1.2 via the further transfer stations 42a... 42c, delivery units having a partially folded sheet and letters arranged in the receiving pocket same recipient address and non-addressed advertising supplements are formed.

Following the collecting route S or at the end of the collecting route S or in the removal device 58 (both alternatives shown) is a Druckvor- direction 43, z. As an ink-jet printer, arranged. The printing device 43 comprises an addressing station. At the printing device 43 and the associated addressing station, the possibly guided in the receiving unit 41 sheet 1.2 are addressed. The address corresponds with the address on the lying in the Aufhahmetasche the sheet letters. Furthermore, on the sheet and advertising messages as well as other information such. As the delivery area or the delivery route, the name of the deliverer, etc. are printed. For this purpose, the printing device may contain further printing stations. In principle, the addressing unit can also be placed elsewhere in the device. The bows 1.2. In particular, they can also be addressed to a removal device before the collection line S or only after delivery of the delivery units. So can z. B. in the sheet feeding to the creasing-folding device 30, a printing unit 60 may be provided. The allocation and transfer of the addressed letters to the receiving units must in any case be coordinated by the control device with the addressing and transfer of the sheets to the receiving units.

A delivery unit can thus contain one or more letters with the same recipient address. It can also be provided that a delivery unit does not contain a letter but only advertising supplements. Since the sheet is addressed anyway, a delivery unit need not necessarily contain addressed letters. So z.
