Description

Technical area

The present invention relates to the field of further processing of printed products. It relates to a method for producing collections of a plurality of N (N = 2, 3, 4, ...) different printed products according to the preamble of claim 1. It further relates to a device for carrying out the method.

State of the art

Under the heading "Direct Mailing» have been known for some time activities in which advertising leaflets, brochures, flyers, printed sheets and the like., Which were otherwise often included for advertising purposes as supplements a newspaper (plugged), collected by several advertisers to make it a variety of collections that contain a printed product from a variety of advertisers and in the form of a small stack to the recipient, eg Households, delivered and distributed.

In order to better handle the individual stack-like collections of printed products during transport and distribution, it is advantageous to take measures to hold together the individual stacks.

From the prior art it is known when one of the printed products is folded to open this printed product and to insert the other printed products in the opened printed product. However, the insertion of the printed products requires a considerable expenditure on equipment, which entails corresponding costs.

However, it is also conceivable to hold the collection of printed products together in that an adhesive or non-adhesive strip is placed laterally around an edge of the collection. Such a technology is e.g. from WO 2012/084 464 A2 or WO 2012/084 494 A2 of the Applicant known. It requires additional effort due to the provision of the strips.

Furthermore, it has already been proposed to connect the printed products of such a collection by the application of adhesive dots with each other, as described in the document EP 2 465 699 A2 of the applicant by way of example. Also in this case, the application of the adhesive dots means an additional expense of material, which leads to additional costs in large quantities.

The same also applies to proposals according to the document EP 2 121 451 B1 to beat or wrap the stack of printed products in a special packaging sheet.

The document EP 0 671 326 A1, which describes a general method for transferring wrapping elements to print product groups, makes the nature of the wrapping elements merely the statement that for this purpose the most diverse wrapping materials come into question.

Document US 4 694 631 A describes a mechanism for automatically feeding individual pre-cut sheets and inserting a personal letter or other pre-cut insert in a personalized envelope. The mechanism has means for automatically adding additional deposits to the envelope and automatically closing the contents in the envelope. The mechanism can also combine precut liners and envelopes fed from multiple sources and convert them into a ready-to-send envelope. Special envelopes are used here which considerably increase the material expenditure and logistics when collecting and sending.

The document US 4 179 111 A discloses a mechanism for folding a sheet, for example an envelope, over which an insert is deposited, and means for moving the sheet with the insert and means for folding the sheet around the insert. Again, it is assumed that an envelope provided with an address, the corresponding material costs required. Again, predetermined envelopes are used which are closed around the inserts.

The document EP 0 952 006 A2 deals with a method for the production of printed items in which at least one sheet of paper, plastic and the like is printed on at least one side and shipped in the closed state, wherein the print data produced by the client and be transmitted via a network to a printing device in which the transmitted print data is printed on the sheet.

This document is also concerned with a wrapper for use in this method, which is made from a blank and folded edges has folded tabs which are joined together by adhesive application. A printout is to be manufactured and shipped cost-effectively, quickly and easily so that a client transmits his prepared print data to the production facility suitable for executing the print job. The production plant makes the print shipment ready for dispatch, so that it is sent directly from the respective production site.

For the wrapping a separate blank is used, which is not adapted to the shape of the casing to be produced, but can be folded without waste. Preferably, this blank DIN format, in particular DIN A4 format, so that conventional sheets can be used for the production of the inventive envelope. With a dedicated device, an adhesive is applied during the transport of the envelope through the device. The production times for the envelope are thereby significantly reduced.

Here, too, a self-sealable closable by adhesive application is generated and used.

Document EP 2 444 325 A1 discloses a system and a method for producing printed transmissions. The system has an accumulator module, in which an enclosure belonging to the respective print transmission and at least one insert are combined to form a sentence. In a downstream folding module, the printing transmission is produced by a folding process. Thus, the printout can be made inexpensively in a simple manner, the envelope is arranged offset to the insert in the accumulator module and folded with the folding module of the entire sentence at least twice. To fold the insert no separate folding module is required. After the folding process encloses the liner.

A printout consists of the envelope, which is made extra from a sheet of paper, and the respective insert, which is located in the enclosure. The number of deposits may change from print to print. The plant has a feeder with which a paper web is fed. It is fed to a cutting unit which divides the paper web into individual sheets of paper. The cut is made transversely to the transport direction of the paper web. Advantageously, the paper web has a greater width than corresponds to the respective format. It is then possible for the paper sheet serving as the envelope of a printout to be produced to have two-sided marginal strips by means of which this wrapping can be closed.

The sheets enter an accumulator module, in which the respective print transmission is assembled. The deposits forming sheets are stacked. In contrast, the sheet forming the envelope is arranged in the transport direction offset from the sheets forming the inserts. The wrapping forming sheet is located below the sheets forming the deposits. Depending on the design of the system, the sheets which form the insert can first be assembled and subsequently the sheet forming the envelope can be transported under the sheets. But it is also possible to first transport the wrapping forming the sheet in the accumulator module and to offset the respective deposits forming paper sheets on him. Once the belonging to a printout sheets are assembled in the accumulator module, this stack is fed to a subsequent folding module. On the transport path to the folding module is at least one glue unit, with which the edge strips of the envelopes forming sheets are glued during passage to the folding module.

This type of production of printed items requires a considerable overhead because of the nature of the envelope.

A disadvantage of all known methods and devices that they need special additional materials that must be kept and provided to be applied to the collections. As far as envelopes are used, the disadvantage is that they require bonding, a special logistics, and above all, large, difficult-to-handle sheets that allow in terms of bonding a complete enclosure even larger deposits, in particular of newspaper printing products would.

Presentation of the invention

It is therefore an object of the invention to provide a method which can be carried out without additional materials and easy to carry out with limited equipment.

It is a further object of the invention to provide a device with which such a method can be performed.

These and other objects are achieved by the features of claims 1 and 5.

The invention is based on a method for producing collections of a plurality of N (N = 2, 3, 4, ...) different printed products, which collections each comprise a stack of printed products, in one around the stack wrapped packaging element is packed. It is characterized by the following steps: Providing the N printed products Formation of an intermediate stack of N-x (x = 1, 2, 3 ...) of the N printed products Providing the x remaining printed products as a packaging element Impacting the intermediate stack in the packaging element

According to one embodiment of the method according to the invention, x = 1.

The inventive method is characterized in that the packaging element is placed on a base, that the intermediate stack is deposited on the packaging element, that only a partial surface of the packaging element is covered by the intermediate stack, and that the packaging element with the remaining surface to is struck around the intermediate stack. In contrast to prior art envelope methods, such wrapping of a printed product of the collection is sufficient and no complete wrapping and therefore no special envelope is required. As described above, the packaging element is formed by at least one printed product of the collection.

In particular, in order to turn the packaging element around the intermediate stack, the remaining surface of the packaging element is bent approximately at right angles upward in a first step, and in a second step the bent-up part of the packaging element is bent back over the intermediate stack.

The invention is further characterized in that some of the printed products have a fold or a binding, that in the formation of the intermediate stack, the folded or bound printed products are stacked so that the folds or bonds a common edge of the Form intermediate stack, and that the intermediate stack is taken with the common edge in the packaging element.

According to one embodiment, the unit of intermediate stack and packaging element is moved through a transfer device for turning the packaging element.

For turning the packaging element in the transfer device movable elements can be used, which are rotated about a transverse to the direction of movement of the unit of intermediate stack and packaging element oriented axis of rotation.

Another embodiment is characterized in that after bending of the packaging element of the bent part of the packaging element is bent back by applying the unit of intermediate stack and packaging element to a conveyor belt and applied to the intermediate stack.

Finally, it is advantageous if the packaging elements are grooved before driving the intermediate stack.

The device according to the invention for carrying out the method according to the invention is characterized in that the device comprises a packing device, in which the packaging element lying partially under the intermediate stack is wrapped around the intermediate stack.

The device according to the invention is further characterized in that the packing device comprises a transfer device and means for moving the unit of intermediate stack and packing element through the transfer device.

The device according to the invention is characterized in that the means for moving the unit of intermediate stack and packaging element are formed as lying in a plane transport routes or conveyor belts, between which a conveyor gap is left free.

The transfer device may comprise movable elements which engage in the conveying gap in the transport path of the unit of intermediate stack and packaging element. The packaging element may be a single sheet, a folded product, a 4-side, an 8-side, stapled, glued or configured in a comparable manner.

For example, the movable elements comprise a bristled brush roll, which is arranged in the conveyor gap and is rotatable about an axis of rotation oriented transversely to the transport direction.

On the other hand, the movable elements but also include rod-shaped driver, which are rotatable about a predetermined axis of rotation through the conveying gap through.

The axis of rotation can be oriented transversely to the transport direction, and the drivers can simultaneously perform an oscillating movement parallel to this axis of rotation with this rotational axis, which between a first extreme position in which the driver in the transport path of the unit from intermediate stack and Protrude packaging element, and a second extreme position in which the drivers are outside the transport path of the unit of intermediate stack and packaging element takes place.

It is also possible that the rod-shaped carrier are arranged on opposite sides of the transport path of the unit of intermediate stack and packaging element in a mirror-symmetrical arrangement.

It is also possible that the rod-shaped carrier for generating the overlapping rotational movement and oscillating movement are each mounted in a concentric circle on obliquely arranged turntables.

Alternatively, the overlapping rotational movements and oscillating movements of the driver but also each be generated by separate mechanical means.

Ways to carry out the invention

Fig. 1 shows a schematic representation of a method according to an embodiment of the invention. The example shown is based on four individual printed products 11a to 11d, which are, for example, folded or bound brochures, advertising leaflets or the like and of which in each case a corresponding supply stack (a pallet or the like) 10a to 10d with a Variety of single copies available and provided.

From the various printed products 11a to 11d or supply stacks 10a to 10d, a printed product, in this case the printed product 11d and the associated stockpile 10d, is selected and held ready for wrapping. In the general case N (N = 2, 3, 4, ...) different printed products one is kept ready and the remaining N-1 printed products are packed by means of this one selected printed product. However, it is also conceivable that more than one printed product, generally x (x ≥ 1) printed products, is selected, and that the remaining N-x printed products are packed with the aid of the x selected ones.

The N-1 or Nx remaining printed products, in the present example of FIG. 1, the three printed products 11a, 11b and 11c, are fed to a collecting device 12, each three different printed products from the three different storage stacks using feeders to an intermediate stack 13 merges and delivers to a subsequent Einpackvorrichtung 14. The Einpackvorrichtung 14 are supplied from the supply stack 10d of the selected printed product 11d in other ways printed products 11d and each used individually for wrapping or wrapping the intermediate stack 13, so that at the output of Einpackvorrichtung 14 collections 15 are issued, in which the intermediate stack 13 in a order the edge wrapped printed product 11d is wrapped. In this way, in the collection 15, all printed products are once present and wrapped without the need for additional packing material and provision.

In the case of the printed products 11a to 11d, if a printed product is particularly suitable as a wrapping material due to its nature (size, material, strength, flexibility, etc.), it is convenient to select this printed product to pack or wrap the intermediate stack 13 therein , In particular, the optical design of the selected printed product can already be adapted beforehand to its specific application, so that information (writing, images, etc.) on the printed product can be recognized well even if the printed product is used as a wrapping material. It is also advantageous that the printed product used for wrapping is placed in a prominent place and particularly clearly outwardly in front of all other printed products within the collection 15.

An embodiment of a packing device 14 is shown in a perspective view in Fig. 2. The packing device is arranged between the end of a collecting device 12 (left edge of FIG. 2) and the inlet region of a transport device 29 (right edge of FIG. 2) and comprises in a transport plane a plurality of successively arranged belt-equipped transport paths 24, 27 and 28. Between the Transport routes 24 and 27, a wide conveyor gap 26 is released, will come back to the bottom.

The collecting device 12 outputs by means of a transfer device 22 from the individual printed products compiled intermediate stack 13, which pass over the upper portion of a coming from below conveyor line 21 to the first transport path 24. In synchronism with each output intermediate stack 13, a print product 11d serving as a packaging element is conveyed upwards by means of the conveying path 21 from below in such a way that it partially, i. with a rear portion in the direction of transport, below which comes the collecting device 12 associated intermediate stack 13, while a front portion of the printed product 11d remains uncovered.

Reaches the unit of partially underlying printed product 11d and thereon intermediate stack 13 with the printed product 11d, the conveying gap 26, the uncovered part of the printed product or packaging element 11d from both sides projecting into the conveying gap 26 and 26 in the conveying gap from below detected upwardly moving rod-shaped drivers 25 of a transfer device 18a and 18b, lifted up and folded against the transport direction to the rear around the intermediate stack. After completion of the wrapping process, the collections 15 are transported via the transport path 28 to the transport device 29 and handed over there.

The rod-shaped carrier 25 of the transfer devices 18a, b, after they have left the area of the conveyor gap 26 up out laterally out of the range of transport distances and returned in a closed circuit down to there again in the area retract the transport line and stand by for a next lifting a packaging element 11d in the conveyor gap 26. A plurality of carriers 25 is arranged on each side so on a arranged obliquely to the transport direction turntable 23 that the individual carriers 25 are aligned transversely to the transport direction and maintain this orientation in the room when turning the turntable 23 unchanged. The rod-shaped carrier 25 thus carry out a movement, which is composed of a rotational movement about an axis of rotation oriented transversely to the transport direction and an oscillating linear movement in the direction of the axis of rotation. But it is also conceivable to arrange the drivers on the turntable so that they lie on the lateral surface of a truncated cone.

The printed products used as a packaging element 11d are individually withdrawn from the supply stack 10d in a laterally transversely arranged feed device (feeder) 16 and transferred as shingled flow to a deflecting device 17, which the packaging elements or printed products 11d individually at a distance over two transport paths 19 and 20th transported to the conveyor line 21, where they then promoted upwards and combined with the coming of the collection device 12 intermediate stacks 13 in the manner described ("teeth"). The printed products 11d can be scored in the shingled stream with advantage by a grooving device 50 arranged there, i. be provided in the middle with a groove, which facilitates the subsequent turning in the transfer device 18 a, b.

While in the plant and handling device 14a shown in FIG. 2, the packaging elements or printed products 11d are supplied from below and the intermediate stacks 13 come to lie correspondingly on the printed products, the situation is in the plant and transfer device shown in FIG 14b the other way round, ie, the packaging elements or printed products 11d are supplied from above, deposited from above on the intermediate stacks 13 and turned down in the conveying gap 26 by means of similar, but differently rotating, enveloping devices 18a, b. Again, the intermediate stacks 13 are transported by the collecting device 12 by means of transport routes 30 and 31 to an output-side transport device 29. The packaging elements or printed products 11d in turn come in a scale flow from a laterally arranged feed device 16 and are then moved individually and at a distance in a deflection device 17 parallel to the transport paths 30 and 31 obliquely down to the intermediate stack and stored on it. Again, a creasing device 50 can be used with advantage.

In the exemplary embodiments of FIGS. 2 and 3, circumferential rod-shaped drivers 25 are used to wrap the packaging elements or printed products 11d around an edge of the intermediate stack 13. According to FIG. 1b, when some or all of the printed products 11a-c have a fold F or a binding, in the formation of the intermediate stack 13 the folded or bound printed products are stacked so that the folds F and the bindings have a common edge K of the intermediate stack 13, and that the intermediate stack 13 is taken with the common edge K in the packaging element 11d. In this context, printed products with bonds are understood to be, in particular, printed products which have a bond produced by adhesion on a specific side. In Fig. 1b is good to see that the printed product 11d of the collection is wrapped around the other printed products and this is not completely wrapped.

But there are other ways to wrap the packaging elements or printed products 11d around an edge of the intermediate stack 13. In the exemplary embodiment of FIGS. 4 and 5, brush rolls 34 and 39 arranged with respective bristles 35 and 40 are respectively used in the conveying gap 26. In both cases, analogous to FIG. 2, the intermediate stacks 13 are deposited from above onto the packaging elements or printed products 11d and the packaging elements or printed products 11d are wrapped around the intermediate stacks 13 upwards. The conveying gap 26 is formed in each case between two transport devices which consist of transport belts 32, 33 or 36, 37 running in parallel and transport the units of intermediate stack 13 and packaging element or printed product 11d between these belts.

In the example of FIG. 4, the bristles 35 of the brush roll 34, which are bent in the direction of rotation, engage underneath the freely emerging section of the packaging element or printed product 11d and, in a first step, bend it approximately at right angles upwards. In a second step, the part of the packaging element or printed product 11d bent upwards is then bent back over the intermediate stack 13 when the unit of intermediate stack 13 and folded-up packaging element or printed product 11d enters the intermediate space between the conveyor belts 36 and 37. To avoid a drop of the free portion of the packaging element or printed product 11d when entering the conveying gap 26, 34 additional conveyor belts 38 may be provided laterally of the brush roller. These additional conveyor belts 38 are not necessary if the free portion of the packaging element or printed product 11d in the transfer device 14d shown in FIG. 5 by a lower brush roller 39 with soft, erecting due to the rotation bristles 40 is turned up.

In the embodiment of FIG. 6, a rotating double arm 41 with two opposite arms 42a and 42b is used in the local handling device 14e instead of brush rollers, which always exchange their position when one of the intermediate stack has passed the conveying gap 26. In the position of the double arm 41 shown in FIG. 6, the double arm 41 with its upper arm 42a just holds the printing product 11d provided for packing so high that the intermediate stack 13 conveyed to the right is under the (stationary or only slowly moving) upper arm 42a can be moved through. At the same time, the printed product 11d strikes the intermediate stack at the top, and this passes between the conveyor belts 36 and 37 with the folded printed product 11d. After passing through the stack, the double arm rotates so far and so fast in the clockwise direction that the other arm 42b now rotates position of the arm 42a shown in Fig. 6 and supports the lower printed product of the next intermediate stack. This process is repeated continuously.

The mechanism shown in Fig. 7 acts with its rod-shaped drivers 48 a, b and 49 a, b similar to FIGS. 2 and 3. The drivers 48a, b and 49a, b are connected in pairs by means of a flexible but long-faithful connecting element 46a, b via reciprocating wheels 45a, b, the entire arrangement of guide wheel 45a, b and driver pair on both sides of the conveyor belt 43 respectively is rotatable about a rotation axis 47.

The drivers 48a, b, 49a, b are thus movable through the conveying gap 26 about the axis of rotation 47 oriented transversely to the transport direction and at the same time as the rotational movement about this axis of rotation 47 perform an oscillating movement parallel to this axis of rotation which is between one axis first extreme position, in which the drivers 48a, b, 49a, b protrude into the transport path of the unit of intermediate stack 13 and packaging element 11d, and a second extreme position, in which the drivers 48a, b, 49a, b outside the transport path of the unit Intermediate stack 13 and packaging element 11d are taking place. The movement of the driver 48a, b, 49a, b is thus analogous to the movement of the driver 25 on the turntables 23 in FIGS. 2 and 3. Also, the arrangement of the mechanism on both sides of the transport path in the same way is mirror-symmetrical, as in the transfer devices 18a, b of FIG. 2 and 3.
