Description

TECHNICAL AREA

The present invention relates, inter alia, to the field of post-press processing. It relates to a method for applying flat, preferably printed, supplementary products to base products according to the preamble of claim 1. It further relates to a device for carrying out the method.

STATE OF THE ART

In the processing of printed products, such as newspapers, magazines, brochures, leaflets, leaflets and the like, the so-called postpress, the possibility has long been perceived to connect to the printed products supplementary products, which then shipped together with the printed products to the customer or end user and provide additional information, which should be limited in time and / or location. In this way, targeted current advertising messages, offers, requests for feedback and the like can be directed to specific customers. By the Applicant offered as an example of the use of such supplements methods and devices under the brand MemoStick ^®.

Since processing speeds of tens of thousands of products per hour usually prevail in the print finishing, special, sometimes very complex mechanical solutions must be found and used for the methods and devices for connecting printed product and supplementary product. A The question of how the connection between the printed product and the supplement product is mediated also plays a special role. Usually adhesives or adhesives are used, in which preferably must be ensured that the supplement product can be removed from the customer again from the printed product without damaging the printed product.

The publication EP 0 606 550 A1 disclosed ( Fig. 1 ) A device for feeding flat products, in particular cards, to a drum-like processing device. A conveyor designed as a belt conveyor transports the products in a conveying direction to a transfer area. Below the slightly ascending conveyor arranged with a Einzelsteuerbaren brackets transfer conveyor is arranged, which is driven to rotate about a rotation axis. In the transfer area, the staples move in the same direction of the conveying direction, the staple mouth of the staples, viewed in the direction of rotation, is directed towards the front and wherein the stapling speed is greater than the conveying speed. Each clamp detects a product at its trailing edge in the transfer area and transports the product to a transfer area. In the course of the movement of the brackets from the transfer area to the transfer area hinged to a wheel-like support member brackets are pivoted against the direction of rotation about a pivot axis parallel to the axis of rotation to advance the products with their trailing edge opposite leading edge, in pocket-shaped receiving parts of the processing device. The receiving parts of the drum-like processing device are bounded by walls extending in the radial direction, which carry saddle-like supports at their radially outer free ends, which extend parallel to the horizontal axis of rotation of the processing device. On the supports astride folded printed products are placed on the transfer area in each case a product is glued by means of the transfer conveyor.

The publication EP 1 112 861 A1 discloses a method and apparatus for joining adhesively coated sheet supplemental products to printed matter having a number of retainer members driven in orbit about a first axis by which replenishers are individually captured at at least one receiving location and after corresponding rotation about the first axis at one Delivery point to be connected to a printed matter. The holding members are thereby guided during transport from the receiving to the delivery point n the region of the hanging and in a second path at least approximately tangentially to the orbit promoted printed products, after which an optionally open printed product at the delivery point by means of a support member supported on the corresponding side and by a arranged with respect to the support member on the other side of the printed product holding member is connected at a designated location with a supplementary product.

The publication EP 1 516 839 A1 shows a method and apparatus for applying a supplemental product, in particular an adhesive tape portion, to a printed product comprising the steps of (1) conveying printed products at a distance from one another to a delivery location, (2) moving holding members having at least one suction organ along one (3) picking up a supplement product at the receiving point by suction by means of the suction member, (4) pressing the supplement product to the printed product at the delivery point by cooperation of the holding member with a support element (5) receiving the supplemental product being in a substantially flat condition, the further steps (6) bending the supplement product to an at least approximate V-shape prior to or upon reaching the delivery point by a flexure without the flexure actively engaging the supplement product, and (7) of the supplementary product to two opposite Pages of the printed product such that an edge of the printed product is overlapped, performed.

The publication EP1 275 607 A1 relates to a device for feeding supplementary products to and pressed on printed products, with a number along a closed orbit in one direction driven, arranged behind one another, at least on the one hand a suction member and at least on the other hand, a support member having recirculating elements, and a control device for the position-dependent control of the circulating elements, wherein the circulation elements are intended to receive a supplementary product at a receiving location with the suction member and press at a pressure point to a printed product, including the circulation elements are moved during their movement from the receiving point to Andrückstelle between spaced apart conveyed printed products and each other, so that in each case on one side of the printed products a circulation element with the held supplementary product and on the other side an adjacent circulation element with the S wearing organ. The circulation elements have on both sides each a suction member and a support member and each suction member is assigned to control its connection to a vacuum source, a suction valve.

The publication EP 1 106 550 A1 refers specifically to methods and a device for transporting especially provided with adhesive surface supplementary products from a receiving point to a delivery point, wherein the supplementary products are detected by means of a moving along a closed orbit holding member at the receiving point and released again at the delivery point. In this case, the holding member rotatably mounted about an axis which is at least approximately perpendicular to the orbit is either left unchanged in a rotational position during transport from the receiving location to the delivery location or about the axis about one axis rotated certain angle until an intended for further processing end position of the transported supplementary product is reached.

Another pamphlet, the EP 0 570 339 A1 , in this connection, discloses a device for glue-like attaching inserts to a side surface of printed products astride on supports of an endlessly circulating conveyor, with a feeder having an adhesive feeding station disposed between a feeder for the inserts and the conveyor. In this case, the feed device arranged above the supports is formed of a plurality of revolving around at least one axis, the printed products in each case a gap of the following consecutive supports immersed carriers, in the orbit of which a feeder and this downstream Klebstoffzuführstation connecting conveyor section of the inserts opens.

The publication EP 2 179 952 A1 Finally, a method and a device for a gluing or adhesive bonding of at least two flat products at least partially reveals one another, in particular printed products with a supplied further product, eg pattern, card, insert, label or the like. In this case, one along a guide line in a scale flow nachgeschlepeses or pushed first product after dissolution of the scale flow in a flow of non-overlapping first products and leaving the guide line then passing through an undershot conveyor area with a clocked same below the first product supplied to this, on a first product facing surface with an adhesive or adhesive second product merged.

In all these cases, complicated procedures and expensive equipment are needed to not only process the supplement products at high processing speeds attributable to the respective printed products and bring them into contact with them, but also to perform the necessary adhesion or gluing process, which is usually effected by pressing, in addition, a counter-holding is necessary if the printed product is transported freely hanging when attaching the supplement product ,

WAYS FOR CARRYING OUT THE INVENTION

The invention is explained below using the example of postpress processing in connection with printed products, but it can be applied more generally to other products suitable for the application, which are referred to as basic products in contrast to the supplementary products.

In post-press processing, where large quantities of mostly paper-based printed products are transported, processed, separated and / or combined in high-speed processes, it is of particular importance that during these processes the printed products themselves or the transport and processing devices There is no electrostatic charge that would cause the printed products to stick together or interfere with transportation or handling. Thus, for example, special devices are used to dissipate and neutralize such harmful electrostatic charges (see, for example, the document DE 26 39 706 A1 ).

On the other hand, it has also been proposed in the stacking of printed products for blocking the stack to charge them electrostatically overall in order to make it difficult for the printed products to slip within the stack (see, for example, document US Pat DE 197 19 935 A1 ). This requires special devices and electrodes.

In addition, the electrostatic charging of signatures has been used to reduce the mobility of the signatures during transport in a folding device controlled by electrostatic attraction (see, for example, the publication DE 197 55 745 A1 ). Also in this case special devices are needed to bring about the desired charge.

The present invention takes a completely different approach to selectively employ electrostatic adhesion in postpress processing without relying on additional equipment and without interfering with electrostatic charging in postpress processing.

However, under special conditions (eg sufficiently high humidity at the application site) it may also be possible to electrostatically charge the supplemental products during the application process (an example of this is shown in FIG Fig. 11 and 12 )

In the focus of the invention are planar supplementary products, which are equipped with a permanent intrinsic electrical surface charge from the production and adhere to other surfaces of the most different material by means of this surface charge and the associated electrostatic field, if they are brought sufficiently close to these surfaces zoom , Different than eg in the publication GB 2 306 437 A or the US 5,776,289 A described, the electrostatic charge of the products to be applied is not applied just before application by any means, but is permanently applied to the product itself.

Such supplementary products are in the form of electrostatically adherent labels or "stickers", for example, from the document WO 93/07535 A1 be known or become offered under the brand Stafix®OFFSET as printable, permanently electrically charged polypropylene films on a supporting cardboard backing.

In Fig. 1 Such an exemplary supplement 10 is shown schematically. The rectangular supplementary product with a few cm edge length in the example may be provided (printed) on the upper side with text-like messages 11 or graphic elements 12 (drawings, pictures or the like) ( Fig. 1 (a) ). It consists for example of a thin, flexible plastic film, which rests individually for better handling before application on a stable base 13 of appropriate size ( Fig. 1 (b) ) or together with other similar supplementary products on a, in particular wound, carrier tape 14 is arranged ( Fig. 1 (c) ).

Such a supplementary product 10 is applied in print finishing on printed products (newspapers, magazines, leaflets, leaflets, inserts, etc.) in order to convey in a flexible and very simple way additional information to persons dealing with the printed products, which are later easily separated from the printed product and separately can be stored or reused. This additional information can be quickly changed and adapted, regardless of the type and content of the printed product and can, for example, specific and up-to-the-minute contact to limited, different circles of end users of the printed products.

The permanent intrinsic electrostatic charge of the supplemental products 10 allows for ease of handling in post-processing without the need for additional electrostatic charging devices or the fear of adverse effects on print finishing due to undesirable charging effects. In particular, the failure-prone application of adhesives can be completely dispensed with. In addition, an impairment or Damage to the printed products during subsequent replacement of the supplementary products practically impossible.

The associated with a certain range electrostatic attraction between the charged supplement product and provided for the application of printed product has the consequence for the print finishing that a pressing of the supplementary product to the printed product is not absolutely necessary. It is sufficient that electrostatically charged supplementary product loosely hang up on the printed product or raise where it automatically engages closely and flat on the surface of the printed product and sticks there. For this reason, various types of application methods and application devices are conceivable in order to apply the supplementary products in a simple and safe manner to the printed products.

A first exemplary application device is in Fig. 2 shown schematically. The application device 15 of Fig. 2 is designed so that it can be easily integrated into the usual print finishing. Within the application device 15, a transport device 16 in the form of a staple conveyor is provided, which, with transport clamps 18, transports the printed products 19 to be processed by means of a pulling member 17 on a linear path past the application device 15.

Underneath the transport device 16, a transfer device, which comprises two circulating transfer units 22 and 24, is arranged, with which individual supplementary products 10 provided at a delivery location B are transferred from the point of supply B to an application location A lying in the region of the transport device 16. The two transfer units 22 and 24 are synchronized with each other and with the transport device 16 accordingly. The transfer unit 22 has over the outer Circumference distributes a plurality of suction organs 23, by means of which provided at the point of delivery B supplementary products 10 held in tangential orientation on the circumference, rotationally transferred to the transfer unit 24 and there transferred to the suction cups 26 at the outer end of the radial holding members 25. The transfer unit 24 then transfers the acquired supplementary products 10 in rotation to the application site A in order to apply them there to the printed products 19 passing by. On the way to the place of application A, the suction heads 26 rotate with the sucked supplementary products 10 so that the supplementary products at the application site A are oriented substantially parallel to the printed products 19 and can be easily applied. In addition, a controlled pivotal movement of the radially projecting holding members 25 may be provided to secure the application process, such that the two adjacent holding members 25 at the application site A temporarily "in the pliers" the pressure product just subjected to the application process "(see Fig. 2 ). As a result, during the application process, the freely suspended print product 19 is stabilized in its position and enables safe application of the supplemental product 10.

To provide the individual supplementary products 10 at the point of provision B, a feed device 20 is provided below the transfer unit 22, which has a circulating transport belt 21 which transports the individual supplementary products 10 in a consecutive row to the point of provision B, where they are then transferred from the transfer unit 22 by means of the suction devices 23 be recorded.

Other types of application and application devices that dispense with the transfer units and devices just described are described in U.S.P. Fig. 3-8 schematically shown in the side view. In all cases, the printed products 19 come here from above by means of a transport device 28 in the form of a staple conveyor transported directly to the site B, where they are brought into contact with the provided to the B supply supplement products 10 so that they can then be transported together with the electrostatically adhering supplement products together. For this purpose, the transport device 28 at the lower end to a guide wheel 29, which deflects the attached to the pulling element, coming from above transport brackets 18 by 180 ° and leads back up.

In the cases of Fig. 3-6 the printed products 19 at the point of delivery B, which is now the same time the application site, released from the transport clamps 18 and stored or dropped onto the supplementary products 10 guided past the point of delivery B. In the cases of Fig. 7-8 the printed products 19 at the point of provision B without release by the transport brackets 18 so far placed on passing on the B supply supplement products 10 that the supplementary products 10 adhere electrostatically to the bottom of the printed products 19 and are taken with them when they move through the transport device 28 Passing the guide wheel 29 are transported away again upwards.

In all cases the Fig. 3-8 a suitably shaped guide element 30 ensures that the brought up (flexible) printed products 19 are guided and pre-bent during the approach to the point of provision B so that they come to rest smoothly and without disturbing relative movement on the supplementary products 10. In the cases of Fig. 3 . 5 and 7 takes place by the guide element 30 a bending in the transport direction, in the cases of Fig. 4 . 6 and 8th a bending against the transport direction.

The provision of the supplementary products 10 takes place in different ways in the different cases. In the embodiments of the 3 and 4 In the case of the application devices 27a or 27b, a feed device 31 is used, in which a supply roll 33 a with the supplementary products 10 occupied carrier tape 14 parallel to or in front of a conveyor belt 32 unwound and at the place of supply B such (eg right-angled) coming from the right down ( Fig. 3 ) or from the bottom to the right ( Fig. 4 ) is deflected, that the supplementary products 10 easily detached from the carrier tape 14 (peel) and are transported along with the printed products 19 on the conveyor belt 32. The carrier tape 14 freed from the supplementary products 10 can then be wound onto a carrier tape roll 34.

In the embodiments of the FIGS. 5 and 6 In the application devices 35a and 35b, the individual supplementary products 10 are withdrawn from a supply stack 40 at the bottom by means of a vacuum device 39 and transported to the delivery site B with a conveyor belt 38 cooperating with the vacuum device 39.

In the embodiment of Fig. 7 the provision is made in the application device 41 with a delivery device 36 in the same way as in FIG. 3 and FIG. 4 , The difference is that the transport belt 32 does not carry out any further transport tasks beyond the transport of the supplementary products 10 to the point of delivery B, because the printed products 19 with the applied supplementary products 10 are transported away from the staple conveyor of the transport device 28.

In the embodiment of Fig. 8 a supply stack 43 is used in the application device 42 instead of a supply roll, in which the carrier tape is held with the supplementary products 10 in a Leporello folding.

The embodiments of Fig. 9 and Fig. 10 are characterized in that in the local application devices 44a and 44b for the transport of the printed products 19, a rotating application drum 45 is used at the point of application A (different from the point of supply B), which is known in its form from the prior art as a collecting drum. In the embodiment of Fig. 9 are the printed products 19 spread astride stored on radial support saddles 46. By means of two transfer units 47 and 50, the individual supplementary products 10 provided at the point of supply B are transferred in rotation to the point of application A, where they are applied and applied laterally to the printed products 19. The transfer unit 50 transports the supplement products 10 by means of suction members 51 to the transfer unit 47, where they are gripped by brackets 49 attached to radial holding members 48 and are transferred in rotation to the application location A. In order to provide the individual supplementary products 10, a supplementary product band 54 (made from a corresponding plastic film) is unwound from a supply roll 55 and subdivided into suitably dimensioned sections by a cutting unit 53 (with a rotating knife). The supplemental product sections corresponding to the individual supplemental products 10 of the previous embodiments are then transported to the delivery site B by means of a transport unit 53, where they are received by the first transfer unit 50.

In the embodiment of Fig. 10 the provision takes place in the same way. The application of the supplementary products 10 differs from Fig. 9 in that the folded printed products 19 in the application drum 45 are inserted into insertion compartments 56 of the drum and the supplementary products are respectively applied to inner sides of the printed products 19.

In the embodiments of the Fig. 11-13 In the local application device 57, the supplementary products 10 are not applied to the individual printed products 19, but to base products in the form of printed product stacks 19 ', which are provided in a transport device 58 in a stacking unit 60 and by means of a conveyor belt 59 are transported past an application site A over. There, a supplementary product 10 is stored on the top side of the respective printed product stack 19 'by means of a transfer unit 63, which contains, for example, information on the further use of the stack (destination, content, etc.). The stack 19 'with the electrostatically adhering supplement product 10 is then enclosed in a filming unit 61 by a film (packaged) and delivered with the film wrapping 62.

The transfer unit 63, with its clips 65 disposed on holding members 64, picks up the replenishers 10 at the point of delivery B, where they are individually provided by a feeder 66 in the form of a printer. The printer can, especially when working with an electrostatic printing principle, at the same time provide an electrostatic charge when printing the supplementary products 10. In the example of Fig. 11 is the printed products stack 19 'due to the uneven thickness distribution of the printed products 19 on the top convexly curved outward. Due to the electrostatic attraction and the flexibility of the supplementary products 10, a simple depositing is sufficient to ensure that the supplementary products 10, despite the convex bearing surface, adhere to the stack in a flat and secure manner. The same applies even more if the stack - as in Fig. 12 shown - is even on the top.

Fig. 13 shows in this case illustratively the timing of the application of the supplementary products 10 on the stack 19 'in the subfigures 1 3 (a) to 1 3 (c). Upon a first contact of the supplement 10 with the stack 19 ', the supplement 10 adheres to its position on the stack 19' ( Fig. 13 (a) ). If the supplement 10 is then released from the bracket 65 ( Fig. 13 (b) ), it sinks, caused by weight and electrostatic attraction, adhering all over to the stack 19 '( Fig. 13 (c) ).
