Device for marking counted sections of sheets

The invention relates to a device for marking counted batches of sheets, especially in multiple panels at the exit of folding machines adjacent to each other Folded sheets, with a conveyor device for receiving the sheets and forwarding them to a sheet delivery after marking the sections of sheets and with a counting device for counting the sheets of a batch and Control of the marking device.

In numerous applications, the folded sheets issued at the exit of automatic folding machines are to be marked in such a way that every batch counted is clearly recognizable. For this purpose, the ones issued by the folding machines have so far been used Folded single or multiple sheets by a simple separating cut or by a strip cut from each other separated and side by side a sheet delivery

fed, for example to a shingled or standing sheet delivery. Short interruptions can be made using a counting device that can be adjusted to the sheet sections to be counted the sheet feed can be controlled at the sheet feeder / so that each sheet section has a larger shingled distance is distinguishable from the previous batch. Alternatively, the entrance belts of a shed or Standing sheet delivery can be accelerated briefly after each counted sheet section, so that through here too a larger scale distance to the previous part, the following part is recognizable.

With both solutions, however, those marked as an imbricated stream must be used Batches are removed immediately, otherwise they will mix up again in the display's collecting device, whereby not only the visibly larger scale distance is pushed together from one lot to the next, but even the sheets that are scaled within the lot are pushed together so that no marking is visible any more is.

The need to remove the parts marked as an imbricated stream before they enter the collecting device causes a high workload, especially with a large number of sheets of sheets next to each other and at high production speeds.

If the sheet feed is briefly interrupted to mark the sheet sections, this also leads to a reduced Production speed.

A lateral pushing of the arches for marking by lateral Relocation is not possible if the sheets are next to each other in several copies or stacks on a conveyor / because the sheets would then be pushed into one another laterally.

The invention is based on the object described above

beneri to eliminate shortcomings of conventional marking devices and in particular to achieve that the once marked parts of single or multiple sheets also in the Collection facilities remain easily recognizable from displays.

This object is achieved in a device of the type specified at the outset in that the conveying device Inclined transport means comprises / by which the sheets transported by the conveyor are transverse to their general one Conveyor track are displaceable, and that the inclined transport means controlled by the counting device selectively in at least one inclined transverse position is adjustable.

In an advantageous embodiment of the device, in which the conveyor is looped over parallel and spaced apart rollers Transport belt is provided, is a selective inclination of the transport belt to the general Conveyor track adjustable. This inclination of the transport belt is in a development of the invention, in which the conveyor belts run in grooves of the rollers, achieved in that at least one of the Rolling is displaceable perpendicular to the general conveyor track. This shift is advantageously done by an electromagnetic drive, by means of which the displaceable roller can be set in at least two different positions is. A particularly simple and advantageous embodiment is that in one of these two Positions the transport direction of the sheets coincides with the general conveyor lane, while in the second Position the transport direction deviates slightly from the general conveyor lane.

Further advantages and features of the invention emerge from the following description of exemplary embodiments and from the drawing referred to. In the drawing show:

FigN i a plan view of an advantageous embodiment the device;

Fig. 2 is a side view of the device shown in Fig. 1; and

Fig. 3 is a plan view of the device with an attached sheet delivery ¹ to illustrate the operation of the apparatus.

The device shown in Fig. 1 for marking counted Batches of sheets can in particular be arranged between the output of an automatic folding machine and a sheet delivery will. It contains a U-shaped support 1 and side parts 2, 3, which are attached to the end face and which are in total form the frame of the device.

Between the side parts 2, 3 is on the sheet delivery facing side of the device a roller 4 rotatably mounted. The roller 4 is driven by a drive belt 5 a motor 6 is driven, which is fastened to the side part 3 via a support. The speed of the motor 6 is infinitely variable. Another roller 7 is arranged parallel to the roller 4 and at a distance therefrom. These The roller 7 is rotatably mounted at the ends of its axis in a pivoting bracket 8, 9, which is attached to the side part 2 or 3 are pivotably articulated. The articulation of the swivel brackets 8, 9 on the side part 2 and 3 is by means of a bearing block 10 or 11 made with pivot point 12. The roller 7 is axially parallel by pivoting the pivoting brackets 8, 9 adjustable and can in particular assume the position shown in Fig. 1, in which it is perpendicular to the by a Arrow P indicated, with the general conveying lane coinciding transport direction of the sheet is shifted. The direction of displacement of the roller 7 is indicated by a double arrow ρ. The amount of displacement of the roller 7

is illustrated in Fig. 1 by the dimension "a".

The displacement of the roller 7 between two different positions is controlled by a double stroke magnet 13, the armature of which engages the swivel bracket 9. This double solenoid 13 is under the control of a (not shown) Counting device which counts the sheets fed in and places them on the sheets corresponding to the desired sheet sections Counter values can be preset.

The rollers 4 and 7 are provided with track grooves 14 and 15, in which conveyor belts 16 run, which are designed as round belts are. These conveyor belts 16 are looped around the rollers 4, 7 with tension.

Between the rollers 4 and 7 and below the upper belt strands the transport belt 16, a support plate 17 is screwed onto the side parts 2, 3.

Support feet 18, which are attached to the U-shaped support 1, are carried by a chassis (not shown), the device preferably being adjustable in height.

Furthermore, sheet hold-down devices are distributed over the width of the device 1 & arranged, which are attached to a traverse 20, which in turn is attached to tabs 21, which are fastened in a height-adjustable manner on the side parts 2 and 3 by means of clamping screws 22.

Fig. 3 shows the operation of the device. The ones coming from a folding machine (not shown) and in four Use separate sheets 23 are carried next to one another by the belt 16 and fed to a delivery 24, at which is a shingled display. Ill of the in Fig. The position shown of the rollers 7 run the Tifänspörtriemeh Schitfäg to the FördeirspUi corresponding to the arrow P? and

thus promote the four adjacent use of sheets with a lateral offset 26 compared to the basic position the roller 7, in which the conveyor belts 16 run parallel to the general conveyor track (arrow P). The four copies of sheets 23 are shingled on the sheet delivery, that is, they are collected clearly offset from one another to the side. In the example shown in Fig. 3, each batch of sheets consists of five pieces, according to the default setting the counting device (not shown) which selectively controls the double lifting magnet 13. By alternating Displacement of the roller 7 to the right and left in FIGS. 1 and 3, individual parts 25 are thus made by Eogen Easily recognizable on the display through the lateral offset 26. Even if the scaled arches of every lot in the Collector are pushed together, the lateral offset remains and is easily recognizable.

The device can be used as a stand-alone, mobile and height-adjustable Unit be designed with its own drive system and thus universally employed at every folding machine output will. In another embodiment, the The device is designed without a chassis and can be screwed or hung onto an automatic folding machine output. At a In another embodiment, the device is an integral part of an otherwise conventional system.
