Fig. 7

4 shows an embodiment of the device with two conveyor devices arranged one behind the other in the conveying direction for separating the printed products in the processing channel.

The device 10 shown in FIG. 1 for processing printed products 12, such as newspapers, magazines and parts thereof a stationary processing channel 14 open towards the top. As well as 2 and 3 it is pointed by two in one Side walls 18, 20 arranged at an angle to one another and below by a bounding these interconnecting bottom 16, with respect to a Vertical the two side walls are inclined to the same side, the first Side wall 18 but stronger than the second side wall 20. The longitudinal direction of the processing channel 14 is perpendicular to the plane of the drawing.

The first side wall 18 has a passage running in the longitudinal direction 22, through which slide cams 24 into the processing channel 14 intervene. The sliding cams 24 are part of a conveyor 26 and intended for this, by means of a feed device 28 in printed products 12 introduced into the processing channel 14 in the longitudinal direction to transport the processing channel 14. Between Sliding cam 24 and the second side wall 20 there is a free space, whose width B is greater than the thickness D of the printed products to be processed 12 (Fig. 2). The sliding cam 24 point to the bottom 16 facing away and the feeder 28 facing one Deflection surface 30, which together with that through the passage 22 imaginary first side wall 18 includes an obtuse angle.

In the embodiment shown in FIGS. 2 and 3, the sliding cams are 24 on a continuously in the conveying direction F - see also FIG. 4 revolving driven member 32, for example one Chain, one behind the other at a distance C. The sliding cam 24 can, however, as with the device according to FIG. 1, on transport elements 34 can be arranged below the processing channel 14 arranged transport channel 36 assigned to this are determined, directly introduced into the transport channel 36 or from Processing channel 14 printed products fed into the transport channel 36 12 to be transported in the longitudinal direction.

The feed device 28 transports the printed products 12 in one Scale formation S, with each printed product viewed in the feed direction Z. 12 rests on the leading one and a distance A between the leading edges 12 'seen in the feed direction Z one after the other Printed products 12 is greater than a distance D 'from Bottom 16 to the farthest from this, in the processing channel 14 projecting part of the sliding cam 24.

The feed device 28 has a conveyor element driven in the feed direction Z. 38 and a pressing element forming a conveying gap 40 therewith 42 on. The conveyor gap 40 ends at a distance E from the floor, which is larger than the dimension G of the printed products 12, measured at right angles on its edge 12 '. This distance is advantageous to keep as low as possible. For example, the difference between E and G is less than 10 or 20% of the dimension G of the printed matter 12th

As is indicated in FIG. 2 by the double arrow H, the distance is of the conveyor gap 40 to the first side wall 18 - measured at right angles to this - larger than about twice as large as that Thickness D of printed matter 12.

The conveyor member 38 of the feed device 28 is closed by a self-contained Conveyor belts 44, but preferably by two or more Conveyor belts spaced apart from one another transversely to the feed direction Z. educated. The conveyor belt 44 is outside the processing channel 14 around a drive roller 46 connected to a drive and in the processing channel 14 by a much smaller diameter Deflection roller 48 out. The back strand 50 of the conveyor belt 44 is around a first roller 52 and then around a second roller 52 'S-shaped deflected by 180 °. While the second roller 52 'is stationary the first roller 52 with the deflecting roller 48 on a common, not shown frame attached, its position in and against the feed direction Z is adjustable to the distance E between the floor 16 and the conveyor gap 40 to different dimensions G of the to be processed Adapt printed products 12. Through this S-shaped deflection of the back run 50 is an automatic length compensation at Change in the position of the deflection roller 48 given.

The active run 54 of the conveyor belt parallel to the first side wall 18 44 delimited together with the roller conveyor 56 Pressure element 42 the conveyor gap 40. The facing the roller conveyor 56 The surface of the active strand 54 is thus at a distance H from the first Sidewall 18 removed. The roller conveyor 56 consists of a large number of Seen in the feed direction Z arranged one behind the other, in one Frame 58 freely rotatably mounted rollers 60, Z in the feed direction seen the frame 58 and thus the pressing member 42 is shorter is as the active strand 54 and that at the end 40 'of the conveyor gap 40 arranged roller of the deflection roller 48 is opposite. So that's it Active strand 54 on the side facing away from the processing channel 14 the pressing element 42 in front and forms a contact surface 62 for the Conveying gap 40 to be printed products 12. Completeness half of it should be mentioned that the frame 58 with the rollers 60, in the feed direction Z seen, fixed with respect to the deflection roller 48, however is movably arranged with respect to the distance to the active strand 54. Due to its own weight and / or by an external force against it Pressed active strand 54, the pressing element 42 turns in its position automatically to the thickness D of the printed products 12 and the thickness of the Scale formation S a. The pressure element 42 on the printed products The force exerted is so great that it is frictional be taken away by the funding body 38.

Devices with a transport channel 36 and an arranged therein Processing channels 14 are, for example, in the CH patent applications Nos. 1997 0325/97 and 1997 0366/97 and the corresponding international patent applications PCT / CH98 / 00015 and PCT / CH98 / 00016. In terms of structure and functionality expressly referred to these documents. The transport channel 36 is limited by wall elements 64 which are arranged at an angle to one another are. Your distance in the bottom area of the transport channel 36 will bridged by floor elements 66. The one behind the other Floor elements 66 are mounted in a self-contained guide and driven in a rotating manner in the conveying direction F by means of a drive device. Transport elements 34 are located on certain floor elements 66 attached, each also carry a sliding cam 24. By the drive the bottom elements 66 are thus both in the transport channel 36 also printed products 12 in located in the processing channel 14 Transport direction F transported by the transport elements 34 or Slide cam 24 on the trailing edge seen in the direction of conveyance F. 12 "of the printed products 12 by pushing. This affects the Form of embodiment of the device according to FIG. 1; basically it is not necessary for the device to have a transport channel 36 must, as can be seen, for example, from FIGS. 2 and 3.

1, the printed products 12 of the feed device 28 fed by means of a transport device 68. This points in rails 70 guided, individual transport clamps 72. A transport facility 68 of this type is, for example, in the CH patent application No. 1996 1818/96. Sloping section 70 ' the rail 70, the brackets move onto a controlled locking element 74 to and are held back by this. The locking element 74 is followed by a controlled opening element 76 is determined, each of the blocking element 74 in synchronism with the conveyor 26 released transport bracket 72 to open the by the transport bracket 72 in a hanging position transported printed product 12 to release. The locking element 74 is followed by drive means 78, around the transport clips released by the blocking element 74 72 each to be transported further in the direction of rotation U. The scale formation S, in which the printed products 12 in the processing channel 14 are introduced, is therefore by the speed of the conveyor 38 and the opening of the transport clamps 72 determined.

As can be seen in FIG. 1, the active strand 54 forms a contact surface 62, for those fed by the transport device 68 and each printed products released in time with the conveyor 26 12th

At the point in time shown in FIG. 2, the feed device 28 is straight released a printed product 12, which is now with its edge 12 ' abuts the bottom 16 and with a flat side on the first side wall 18. The sliding cam 24 is on the trailing seen in the conveying direction F. Side edge 12 "of this printed product 12 comes to rest, to move it forward in the longitudinal direction of the processing channel 14 push. A printed product following this printed product 12 12 is held in the conveyor gap 40, overlaps that with his part protruding from the conveyor gap 40, viewed in the feed direction Z. the edge 12 'has not yet reached the sliding cam 24.

At the time shown in FIG. 3, the sliding cam 24 has the Bottom 16 and printed product 12 in contact with the side wall 18 Direction of conveyance F advanced, the sliding cam 24 in Direction of conveyance F still seen in the area of the printed product 12 is located, which is held in the conveyor gap 40. This is in the course of Inserting into the processing channel 14 with its edge 12 'on the Deflection surface 30 comes to rest, making it in the direction of the first side wall 18 deflected away to the second side wall 20 has been and now the free space B between the sliding cam 24 and passes through the second side wall 20. Since the printed product is still in Conveying gap 40 is held, it can from the sliding cam 24 or that of this moving printed product 12 can not be taken. The Deflection surface 30 thus forms a means 30 'for steering in the conveying gap 40 held printed products 12 from the effective range of the sliding cam 24 and thus to prevent the transport of these printed products 12 through the sliding cam 24.

In FIG. 4, only the conveyor device 26 is included in the device 10 which is driven continuously in a rotating manner in the conveying direction F. Traction element 32 sliding cams 24 arranged one behind the other at a distance C shown. The feed device is marked with a dash-dot line at 28 Line indicated. The feed direction Z is perpendicular to Conveying direction F and therefore at right angles to the longitudinal direction of the processing channel. The time shown in Fig. 4 when processing the fed by means of the feed device 28 in scale formation S. Printed products 12 correspond to the point in time shown in FIG. 3. The foremost printed product 12 seen in the feed direction Z Scale formation S is from the deflecting surface 30 of the sliding cam 24 have been deflected from its effective range. This sliding cam 24 and the two other sliding cams 24 shown are each on the trailing Side edge 12 "of a previously fed printed product 12 and push them further in the direction of conveyance F. The scale formation S and the feed speed as well as the speed and the distance between the sliding cams are matched to one another such that a printed product 12 meets with each slide cam 24. There the distance C between successive slide cams 24 is greater than the length of the edge 12 'of the printed matter 12, the in Scale formation S printed products introduced into the processing channel deflected in the direction of conveyance F and at the same time isolated. It is at first glance it can be seen that the conveying speed of the Feeder 28, even with a large processing capacity of the device 10, can be kept low.

5 shows the device 10 in the same manner as in FIG. 4. An opening device 80 is assigned to the processing channel is intended to be transported past it by means of the conveyor 26 Open printed products 12. It is in the conveying direction F seen downstream of feeder 28 and upstream one arranged further feed device 28 '. The latter is intended in the printed products 12 opened by means of the opening device 80 to introduce another printed product 12a each. The take along and simultaneous separation of the printed products fed in scale formation 12, 12a by means of the conveyor 26 occurs exactly the same way as in connection with FIGS. 1 to 4 described.

FIG. 6 shows the device 10 according to the invention in the same way as FIG. 4. The feed direction Z of the feed device 28 now has, in addition to a component Z _z running at right angles to the feed direction F, a component ZF running in the feed direction F. The feed device 28 in turn feeds the printed products 12 into the processing channel in a scale formation S, the edges 12 ′ here also running parallel to the bottom 16; compare FIGS. 1 to 5. In this scale formation, not only the edges 12 'but also the side edges 12 "are spaced apart from one another. Here, too, a sliding cam 24 runs onto the printed product 12 that has just been released from the conveyor gap 40, and lies on the Side edge 12 "and takes the printed product 12 in the conveying direction F. It can be seen that, at the same speeds as in the embodiment according to FIGS. 4 and 5, in the embodiment according to FIG. 6, the acceleration forces acting on the printed products 12 are smaller when the pushing cams 24 run onto the printed products 12 because these are already being inserted be conveyed into the processing channel with a component in the direction of conveyance F.

In the embodiment shown in FIG. 7, the conveyor device 26 two conveyors 82, 84 connected in series in the conveying direction F. The first conveyor 82 in turn has an endless traction element 32 the sliding cams 24 are arranged one behind the other at a distance C ', now the distance C 'is smaller than the length of the edges 12' of the processing printed products 12. The tension member 32 is by two Deflection wheels 86, with the downstream deflection wheel 86 another deflection wheel, not shown, is mounted coaxially. Around this is a pull member 32 'of the second conveyor 84, on which now further sliding cams 24 'arranged one behind the other at a distance C. are greater than the length of the edges 12 'of the printed matter 12. The speeds of the traction members 32, 32 'are one on the other matched that in each case in the area of the deflection wheel 86 Slide cam 24 'coincides with a slide cam 24.

The printed products fed in scale formation S are now by being carried by the sliding cam 24 in the conveying direction F deflected, but not isolated. It will be a new scale-like formation formed in which the printed products in the conveying direction F seen overlap. The printing products 12 are separated then in the area of the second conveyor 84 due to the higher speed, with which the sliding cam 24 'revolve.

Of course, it is also conceivable, analogous to FIG. 7, the supplied Printed matter in processing channel 14 in the scale-like formation to leave and not to separate.

Both the conveying element 38 and the pressing element 42 can be designed differently. For example, the funding body 38 arranged one behind the other, driven rollers. Similar can the pressure element 42 an endless belt or a pressure rail exhibit.

Of course, it is also possible that the printed products already in scale formation, for example from a storage roll, the Feed device 28 are fed.

The conveyor elements 24 "can also be formed by conveyor brackets, the printed products 12 introduced into the processing channel clamp their transport in the direction of conveyance F. An example of one Conveying clamp 24 '' 'is indicated by dashed lines in FIG. 6. She points a deflecting surface 30 on the entrainment of held in the conveyor gap 40 Printed matter 12 prevented.

It is also conceivable for the floor to be circumferential in the conveying direction is and the conveyor elements are arranged on it.
