Description

The present invention relates to a method and a Device for labeling printed products, such as Newspapers, magazines, supplements and the like, according to the preamble of claim 1 and 6 respectively.

A method and a device of this type are known from the EP-A-0 096 228 and the corresponding U.S. Patent No. 4,538,161 known. The facility has a writing station with an inkjet pen over it a conveyor runs in the horizontal direction. This points one behind the other on a pulling element at the same distance arranged brackets seen in the conveying direction towards the rear of the clamp mouth. Any parenthesis holds a printed product at a right angle to the direction of conveyance bleeding edge and pulls it with this Edge opposite trailing edge area an overlay of the writing station overlying it away. The lower outside facing the writing station Every print product is from the leading one Printed product overlapped like a scale, so that each only the trailing edge section is free, in which the printed products using the inkjet pen be labeled.

The known method and this known device are ideally suited, the printed products on one outside to label in the edge section. But you are neither intended nor suitable to print products on the to be able to label other outside.

It is therefore an object of the present invention to propose a generic method and a generic method Creating facility that labeling of print products optionally on any which allows two or both outer sides.

This task is accomplished through a process and with a facility solved, the or the features of claim 1 or 6.

According to the invention there are two writing stations that one of the two outer sides of To label printed products. The inventive Exposing an area of the at least one outside allows labeling of printed products in places, those due to the scale-like overlap of the printed products were previously covered. Can continue through exposing areas accessible to the writing station be made beforehand by the conveyor were covered.

Preferred developments of the method according to the invention and the device according to the invention are in the dependent Claims specified.

Fig. 11

10 enlarges part of the device shown in FIG. 10, viewed in the direction of arrow XI in FIG. 10.

The device shown in FIG. 1 has a conveyor device 10 with a dash-dotted line and in the conveying direction F continuously driven tension member 12 arranged at the same distance one behind the other controllable brackets 14. The self-contained train organ 12, for example a chain, is as is well known and as can be seen in FIGS. 2 and 4, in a channel guided and in a takeover area 16 to drive deflected around a deflection wheel 18. Conveyors 10 of these Types are, for example, in EP-A-0 600 183, EP-A-0 557 679, EP-A-0 557 680 and CH-A-644 816, and the corresponding U.S. Patent Nos. 5,395,151, 5,356,128 5,388,820 and 4,381,056. The guided traction element 12 thus determines a trajectory 20 for the brackets 14.

Below the deflection wheel 18 is a belt conveyor Feed conveyor 22 arranged, intended for this is, in the feed direction Z printed products 24, which in a scale formation S are arranged in the feed direction Z seen every printed product 24 on the trailing lies to promote against a stop 26. Each clamp 14 encircling the deflection wheel 18 is gripped in each case the uppermost on the stop 16, by means of a suction device lifted printed product 24, as in EP-A-0 551 601 and the corresponding U.S. Patent No. 5,398,920, and transports it hanging in a vertical direction extending first connecting to the deflection wheel 18 Section 28 of the movement path 20 from the bottom towards the top a first writing station 30 past. The printing products 24, it is preferably multi-leaf folded newspapers, magazines, parts thereof or side dishes, are from the brackets 14 at a right angle held to the conveying direction F edge 32 and transported with scale-like overlap, so that from one of the first writing station 30 and the first outer side 34 facing away from the traction element 12 Printed product 24 only an edge area 36 freely accessible that is along the edge 32 in the first section 28 that trailing edge 38 extends.

The first writing station 30 has an ink jet pen 40, as described in EP-A-0 096 228 and in corresponding U.S. Patent No. 4,538,161 is and which is intended, all or certain printed products 24 in the edge area 36 of the first outer side 34 to label. With the inscription 42, see Fig. 2, for example, the address of the recipient, a code for further processing, a message or similar. The label 42 is in one adjoining one side edge 44 of the printed products 24 Labeling field 42 'attached that only extends over a portion of the edge region 36. The Labeling field 42 'can of course also be sent to connect other side edge 44 'as shown in FIG. 3 shows, are located in the middle of the edge region 36 or extend all over this.

Downstream of the first section 28, the conveyor device 10 a also running in the vertical direction second section 46 of the movement path 20, in which the conveying direction F runs from top to bottom. The first section 28 and second section 46 are over an arc section 48 connected to each other, which is approximately runs in the shape of an upside down U's. There the printed products 24 in the hanging position by means of the clamps 14 transported, they will pass through the Sheet section 48 turned over, so that now the first Outside 34 in the second section 46 facing the tension member 12 and the other second outside 50 of a second Writing station 52 is facing. This is regarding the Path of motion 20 on the same side as the first Writing station 30 arranged and substantially the same educated. Due to the scale-like overlap of the handled print products 24 is now from the second outside 50 each one along the now leading edge 38 freely extending edge region 36 ', in which the second writing station 52 now has another Label 54 attaches or can attach, as this Fig. 4 shows. The corresponding further labeling field 54 'can in turn on one of the two side edges 44,44' connect, over the entire edge area 36 'or extend in the central area. It goes without saying itself that the label 54 different or same content as the label 42 can be.

Fig. 5 shows the printed product shown in Fig. 3 24 with the one attached to the second outside 50 Lettering 54. This is opposite lettering 42. With the device shown in Fig. 1 can thus the printed products 24 optionally on one of the or on both sides 34.50. It is of course also possible, some of the printed products 24 not to label the scale-like formation, some print products 24 only on one of the outsides 34.50 and others on both outsides 34.50 to be labeled.

Seen in the direction of conveyance F, the second section closes 46 to a transfer section 56 in which the Printed products 24 by opening the clips 14 one Further processing station, for example a drum-like one Device for collecting, collating or plugging in of printed products.

Such further processing devices are, for example from EP-A-0 550 828 and EP-A-0 341 425 and the corresponding U.S. Patent Nos. 5,324,014 and 5,052,667 known.

The device shown in FIG. 6 corresponds to that in 1 and is therefore not described in more detail; designate the same reference numerals same items. The only difference is that in the takeover area 16 now only every second Clip 14 is equipped with a printed product 24. This has the consequence that the overlap of the printed products 24, seen in the conveying direction F, compared to Fig. 1, with the same size printed products 24, reduced is. In any case, the width of the border areas 36, 36 ', seen in the conveying direction F, in comparison to FIG. 1 enlarged; with the same distance between the brackets 14 corresponds to the width in the device according to FIG. 6 the edge regions 36, 36 'twice the distance between the brackets 14, in the device according to FIG. 1 only the simple distance.

As can be seen in particular from FIGS. 7 and 8 the enlargement of the edge regions 36, 36 'means that the labeling fields 42 ', 54', perpendicular to the edge 38, have a larger extent, and thus the lettering 42,54 can be attached in places that at the operating mode of the device according to FIG. 1 from one neighboring print product 24 are covered.

Holding the printed products 24 by means of the clips 14 in a hanging position and the passage through the arch section 48 has the consequence that all printed products 24 handled are fed to the second writing station 52. The conveyor 10 is thus between the first and second Writing station as an arrangement for exposing one of another printed product 24 covered area, of the edge region 36 'of the second outer side 50.

FIG. 9 shows an enlarged portion of FIG Arc section 48 and the subsequent second Section 46 of the conveyor 10, as well as the next the second writing station arranged after the second section 46 52. The print heads of the inkjet pen 40 are stationary on a frame 58, preferably in the direction fixed at right angles to the conveying direction F. The adjustability enables labeling in different sections of the edge region 36 '. On the frame 58 guide rails 60 are also arranged, the side of the print heads and towards the Conveyor device 10 runs past this, around the leading edge 38 in the second section 46 of the printed products 24 and to prevent that these are queued at the writing station 52 during the transport. It is understood that the first writing station 30 no such guide rails 60 required, since there the Printed products 24 transported past with trailing edge 38 will.

Printed products guided past the second writing station 52 24 can in the exposed edge area 36 ' this writing station 52 facing the second outside 50 can be labeled.

The brackets 14 are at a right angle to the conveying direction F extending axis 14 'pivotable, this enables the transport, even of relatively small printed products 24 hanging. Are only large format printing products 24 to process, it would be conceivable, not pivotable Provide brackets 14, the mouth of which is at least approximately is arranged at right angles to the conveying direction F. It is also understand that by controlled pivoting of the Brackets 14 areas of the outer sides 34.50 of the printed products 24 exposed for labeling or exposed Areas 36,36 'can be enlarged. For example possible with the one shown in FIGS. 1 and 6 Facility, the bracket 14 immediately after exiting the Labeling by means of the first writing station 30 of the of this clamp 14 held printed product 24 from which seen in the direction of conveyance F to the rearward-facing position, clockwise in a direction approximately perpendicular to the conveying direction or swivel forward facing position. Thereby becomes the coverage of the next print product 24 reduced. The pivoting of the brackets 14 takes place in this case by suitable control means, for example a backdrop; like this given in above Documents is disclosed.

The form of training shown in Figure 10 of the inventive Device has a wheel-shaped Conveyor 10 on as in the older EP-A-0699611 shown and described in detail is. The wheel-like conveyor 10 can also as in EP-A-0 606 550 and the corresponding U.S. Patent No. 5,425,837 disclosed be. Reference is expressly made to these documents.

From a continuously in the conveying direction F about its axis of rotation 62 ' rotatably driven carrier wheel 62 are in fixed circumferential distance from radial boom 64. On everyone this arm 64 is designed as an angle lever Support arm 66 and a double-armed control lever 68 pivotable stored. At the free end of the approximately in the radial direction extending lever arm of each bracket 66 is a bracket 70 pivotally mounted, also via a coupling 72 with one lever arm of the relevant control lever 68 connected is. On the other lever arm of the support arm 66 and control lever 68, a control roller 74 is freely rotatable mounted, each in a running around the carrier wheel 62, closed tax groove 76.76 'are guided. The control grooves 76,76 'are on a fixed control ring 78 excepted.

By means of the control groove 76, the pivot position of the support arms 66 with respect to the arms 64 and the control groove 76 ' Determined pivot position of the brackets 70. By swiveling one arm 66 allows the distance to the neighboring one Change brackets 70.

The brackets 70 are in the conveying direction F towards the front, open mouth 70 'to a takeover area 80 moves where they start with one from a stack 82 withdrawn printed product 24, if necessary a card or a folded sheet.

The control grooves 76, 76 'are designed such that when Detect the print products 24 the speed of the Clamps 70 by pivoting the support arms 66 counterclockwise, i.e. counter to the direction of rotation F, reduced is, this comes from the short distance between the two themselves Stacks of staples 82 located 70. In one The area following the takeover area 80 then becomes the Support arms 66 pivoted forward again clockwise, what is the distance to the trailing bracket 70 enlarged and thus the overlap of the corresponding Printed products 24 reduced or in the case of small printed products 24 even picks up.

Regarding the takeover area 80 in the conveying direction F, um offset about 270 °, there is a transfer area 84, in which the printed products 24 to a further processing station 86 are handed over. At the processing station shown 86 is a drum-like device with a common horizontal Axis of rotation 88 arranged around, in the direction of rotation U driven, saddle-shaped pads 90 on which the folded by means of an opening device 92 Print products 24 astride. Here the brackets 70 through the control groove 76 'counterclockwise twisted and is through the control groove 76 Spacing of the clamps 70 adapted to the spacing of the supports 90, so that the mouth 70 'is concerned in each case Brackets 70 is aligned on a support 90.

A first is located to the side of the opening device 92 Writing station 30 and with respect to the path of motion 20 the other, radially inner side, a second Writing station 52 arranged stationary, see also Fig. 11. The writing stations 30, 52 are designed to Printed products 24 on their radially outer first Outside 34 or radially inner second outside 50 to label. Labeling is optional on one of the two outer sides 34 or 50 or simultaneously 34 and 50 on both sides.

As is clear from the three directly upstream of the Writing stations 30, 52 shown brackets 70 recognizable is in front of the writing stations 30, 52 Section 94 of the approximately circular movement path 20 the brackets 70 their mutual distance by pivoting the support arms 66 reduced in a counterclockwise direction and thus the scale-like overlap of the corresponding Printed products 24 enlarged. Here but at the same time the support arm 66 of the at the writing stations 30.52 past printed product 24 clockwise is pivoted, is by the subsequent printed product 24 covered area 96 of the first outside 34 reduced or canceled, resulting in a large area Inscription of the first outside 34 by means of the first Writing station 30 is enabled.

By the mentioned simultaneous pivoting of the support arms 66 in opposite directions also becomes an area 96 'of the radially inner second outer side 50 of the printed products 24 exposed, so that this second outside 50 can be labeled over a large area.

The deceleration and acceleration of the brackets 70 serve in the shown example both of uncovering areas 96, 96 'of the printed products 24, as well as the introduction of the radially outside, the first outside 34 having Part of the folded printed products in opening cams 98 of the opening device 92, as is also the case in the older EP-A-0699611 is.

As indicated by dash-dotted lines in FIG. 10, the first and second writing station 30, 52 also between the Takeover area 80 and the opening device 92 or the transfer area 84, the movement path 20 of the clamps 70, seen in the radial direction, between the opposite writing stations 30.52 passed through.

It is also conceivable to use a 1 on the pivotable Brackets hanging along an approximately straight and horizontal Transporting the trajectory section and the two writing stations below this trajectory section and to be arranged offset in the conveying direction. The Printed products are then with their free edge area trailing and resting on support rails over one Writing station and leading with its free edge area and resting on support bands that are related to the Clamp speed driven at higher speed are moved over the other writing station. This type of transport and support creates marginal areas of the printed products exposed.
