Description

The present invention relates to a method and apparatus for inserting and / or insertion of printing supplements, such as sheets, (folding) sheet, CD's, samples u. Like., In main printing products according to the preamble of claim 1 and the preamble of claim 7.

When inserting or inserting in the print finishing the insertion of sheets, (folding) sheet, CD's, samples u. Like. In finished products (for example, newspapers, magazines, brochures) understood. The inserted printing inserts are mostly promotional purposes. The process section is prior to packaging the relevant major print product. Are known packaging systems in the modular system consisting of a Druckhauptproduktanleger, a number of supplements and label dispensers for insertion and placement of the printing supplements in or on the main printing products, a film wrapping machine for packaging the main printing products with the printing supplements, an inkjet printer and postal code control, duplexer and stacker.

The main printing products are transported in the direction of their format height, ie with their back bond along the conveying direction, in a conveyor channel of carriers of a conveyor at intervals. To insert the printing inserts, the main printed products are opened by lifting the leading edge of the first sheet of the main printing product by means of a rotary nipple and transferring it downstream to baffles. The first sheet is guided on the baffles at an acute angle of at most 30 to 45 ° to the main part of the main print product, so that the main print product is substantially opened only in the front cut, while the intended for the printing inserts placement side is still more than 60% by the open Sheet is covered. To lift more than the first sheet of the main print product is pushed with its leading foot or head side against an opening sword. After inserting the printing supplements, the main printed products are closed by returning the opened sheets and it may be further printed supplements placed on the top of the main printing product.

The printing supplements are isolated from magazines with known rotational or drum feeders oriented transversely to the conveying direction of the main printing products and supplied to the continuously advancing main printing products essentially transversely to their conveying direction in order to be inserted through the opening in the front section of the main printing products. The supplied printing supplements undergo a change of direction after feeding, whereby the processing power of such loading and inserting machines is limited in terms of a reliable and gentle product feed of the printing supplements.

EP 1 231 176 A1 describes a device with which the printing inlays are fed in a substantially horizontal plane obliquely to the conveying direction of the main printing products, wherein the leading side edge of the printing inlays is parallel to the guide wall of the conveying channel. Due to the oblique transport direction results in a speed component in the conveying direction of the main pressure products, whereby the acceleration shock is reduced by the driver of the conveyor channel at the trailing edge of the pressure shims. The speed component perpendicular to the conveyor channel is reduced, so that the impact speed of the pressure shims is reduced at the opposite guide wall or in the back of the main printing product.

From EP 0 738 682 A1 a device for feeding pressure supplements is known, in which the pressure shims supplied transversely to the conveying direction are pre-accelerated in the conveying direction via two vacuum disks rotating in the same direction. The substantially horizontally arranged and each provided with a suction vacuum discs detect the pressure shims in each case one point and force the pressure supplement during a 90 ° rotary motion on a corresponding translational movement. Due to the occurring acceleration forces only light and stable pressure supplements can be processed with this device.

The present invention is based on the object, a method and an apparatus for inserting and / or insertion of printed inserts, such as sheets, (folding) sheet, CD's, samples u. Like. Provide in printing main products according to the preamble of claim 1 and the preamble of claim 7, which allows it to supply printing inserts with high processing power reliable and gentle on the product main products. Another object of the invention is to enable the positionally accurate insertion or insertion of the printing supplements.

This object is achieved in the method according to the invention by the features of the characterizing part of claim 1. The device solves the problem with the features of the characterizing part of claim 7. The idea of the invention is to open the main print product so far that the print inserts from above on the intended placement side in the main printing product can be deposited and thus fed to the main print product in the same direction. Abrupt changes of direction in the feed of the printing inserts no longer occur, whereby a product-gentle feeding at high speed is made possible. In particular, labile printing supplements are no longer twisting and are stored in the exact position on the placement page. The insertion or insertion of the printing inserts under the trailing edge of the printing supplement at the driver and / or planting a side edge in the back of the main printing product is no longer required, so that a predeterminable, positionally accurate placement of the printing supplements in the main printing product is possible. Preferably, the at least first sheet of the main printing product is opened by about 90 °, so that the printing supplements can be fed in close to the back bond and can be deposited on the placement side.

In Figs. 1 and 2 in each case a generally designated 1 insertion machine is shown, for inserting printing supplements 3 a, 3 b in brochures 2 with two investors 11 and 16 and for placing a printing enclosure 3 c with a third feeder 11th or 16 is equipped. The differences between the insertion machine in Fig. 1 to the relevant embodiment in Fig. 2 will be discussed later in the description.

The brochures 2 are continuously transported forward in a conveyor channel 4 of carriers 6 of a conveyor chain 5 at equal mutual distances, wherein the back binding of the substantially flat lying transported brochures 2 is oriented longitudinally to the conveying direction F of the conveyor channel 4. This is formed from a channel bottom 7 and a lateral guide wall 8. From Figs. 3 and 4 it can be seen in that the conveyor channel 4 is a conveyor channel used in collating machines, with a horizontal channel bottom 7 a and a channel bottom 7 b inclined transversely to the conveying direction F and the guide wall 8, the back of the brochures 2 being guided on the guide wall 8.

For inserting printing supplements 3 a, b, c, the brochures 2 must be opened. This is done in the embodiment of Fig. 1 with a rotary opener 21, which, arranged near the front section of the brochures 2, the respective first sheet 9 of the brochures 2 sucks with a rotary valve 23 controlled suckers 22 and passes to a baffle 24. The rotational movement of the suckers 22 is set in such a way that the leading edge of the first sheet 9 is sucked in at almost synchronous speed and lifted off the paperback 2. In the embodiment in Fig. 2, a fixedly arranged opening blade 31 is used, which punctures with a correspondingly shaped tip in the foot or head section of the brochure 2 and thus is able to lift several top sheets 32 of the respective brochure 2.

The raised sheets 9 and 32 are further opened with the baffle 24 or opening blade 31 progressively wound in the longitudinal axis during conveying of the brochure 2 and subsequently transferred to baffles 25 and guide rods 26. The blades 9 and 32 are pivoted by an opening angle α of almost 90 °. The baffles 25 and guide rods 26 provide the leaves 9 and 32 is a support and guide surface and form with the guide wall 8 a guide channel 27 in which the lifted sheets 9 and 32 are guided safely. After opening a particular comprising several sheets 32 upper leaflet part is provided by a transport support for these lifted sheets 32 for proper promotion of the brochures 2 by cams 30 arranged along the guide channel 27, endless conveyor belt 29 the brochures 2 in addition to the respective driver advance the conveyor chain 5 sliding.

Through the 90 ° opening, the placement side 10 for the einzueckenden printing supplements 3 a, b is almost completely accessible from the vertical direction. As a result, a feeding of the printing supplements 3 a, b in the conveying direction F of the brochures 2 is made possible. In the inserting machine 1 from FIG. 1, so-called suction belt feeders 11 are used, from the magazines 12 of which a respective lowermost printing inlay 3 a, b, c is advanced in the conveying direction F in accordance with the cycle for conveying the conveyor chain 5 and take-off rollers 13 are fed. About an obliquely downward on the brochures 2 zufördernden Clamping conveyor 14 with associated lateral support plate 15 reach the pressure supplements 3 a, b in synchronous conveying movement on the intended placement side 10 of the brochure 2. The thus resulting feed direction 20 lies in a vertical plane which is defined by the conveying direction F.

In the second embodiment of the inserting machine 1 shown in FIG. 2, instead of the suction belt feeder 11, so-called drum feeders 16 are provided for feeding the printing inlays 3 a, b, c. They each have a singling drum 18, which deducts the printing sheet 3 a, b or c from a magazine arranged above 17 and transfers to a transfer conveyor 19 for storing the printing supplement 3 a and 3 b on the placement page 10 of the brochure 2 with a obliquely downward feed direction 20.

After inserting the printing supplements 3 a, b, the opened sheets 9 and 32 are returned by a beginning in the guide wall 8 return plate 28 to the brochure 2, whereby the brochure 2 with the inserted pressure supplements 3 a, b is closed. It is now possible to supply additional printing supplements 3 c, which are then placed on the upper side of the brochures 2. In FIGS. 1 and 2, a further suction belt feeder 11 or a further drum feeder 16 is shown for this purpose.

By means of the method according to the invention, it is now possible for the first time to feed the printing inlays 3 a, b, c to the main printing products 2 in the same conveying direction F, 20. Transversal movements or directional changes in the conveying movement are not required. The storage takes place at a synchronous conveying speed, whereby positionally accurate feeds are made possible without an edge of the printing enclosure 3 a, b must rest either along the binding or in front of the driver 6. This allows in particular higher processing performance. In addition, it is possible that printing inserts 3 a, b are fixed in the main printing product 2 in certain positions, such as the gluing of cards or the electrostatic fixing of the printing supplements 3 a, b for a functionally reliable further processing in the subsequent packaging. Already with an opening angle α of 60 ° more than 50% of the surface of the placement side 10 are accessible from above, so that for smaller printing supplements 3 a, b a feed in the conveying direction F is possible.
