Abstract

The method for removing individual items from a group of overlapping flat items (2) on a conveyor (F.1) uses a deactivating device (3) which unfastens gripping components (1.2) on the first conveyor. A switching device moves the items in the group on to a second conveyor (F.2) while the unselected items continue along the first conveyor. An Independent claim is included for a device for carrying out the above method.

Description

The invention is in the field of conveyor technology and relates a device according to the preamble of claim 1. The device relates to the delivery of scale flows, that means the promotion of a large number of flat objects, such as For example, printed matter (e.g. newspapers or magazines) that are in a Row and are partially overlapping each other in the conveying direction. The device according to the invention serves from such a shingled stream Scale stream parts, i.e. individual objects or groups of successive objects.

Scale streams, in which, for example, printed products from rotary printing presses are also designed in the further processing of these printed products a frequently used formation for the extraction and also for the intermediate storage (e.g. intermediate storage of printed products in rolls Scale streams). Scale streams of printed products or of other, flat objects are, for example, on conveyor supports, e.g. on conveyor belts, conveyed freely lying, whereby for conveyor sections in which because, for example, the slope is too big, a loose support is not it is possible to provide double bands between which the shingled current is held.

For longer conveyor lines with complicated lines (inclines, curves, Twists) are also used to fund a stream of shingles is held laterally, for example, by holding means. For such a held Promotion of a shingled stream, for example, clamping members are used which are arranged on a transport organ (e.g. transport chain). Depending on the rigidity of the objects forming the scale flow, depending on the course of the The flow of shed and, depending on the requirements of the promotion, the shingled stream held on only one side or on both sides.

The distance between the clamping members must be chosen so that everyone Subject of the shingled stream held by at least one clamping member becomes. If each object is held by more than one clamping element, it forms the Shingled stream a stable band. Will every object of the scale flow of Held only one clamping member, the stream of shingles breaks up into sections, whereby each section consists of a plurality of objects and each such plurality is held by objects by a clamping member.

Funding with holding means that are suitable for the promotion of scale flows, are described, for example, in publications CH-344085, CH-559692 or EP-0095602.

For removing individual objects or groups of successive ones Are objects from a loosely conveyed scale stream known various methods. From a stream of shingles, with overhead leading object edges, for example a single object is removed, by grabbing its leading edge and accelerating the object is drawn from the stream of scale. Such withdrawal is for example described in publication EP-0116015 (US-4577855). For the removal of groups of successive objects becomes the Scale flow at the end of a pivotable part of the conveyor with suitable Funds separated and then becomes the pivotable part of the funding document pivoted in such a way upwards or downwards that it is connected to a further funding connects, which removes the removed shingled stream parts. If the too Removing scale flow part passes the pivotable area of the conveyor support the stream of shingles is separated again and the conveyor support is pivoted back.

The publication US-4424966 describes a device for removing Scale flow parts from a loosely conveyed scale flow. The device has a pivotable conveyor belt part and a pivotable rake. The rake serves to push away the tail end of a removed part of the dandruff from pivotable conveyor belt part in its pivoted position and to bridge the pivotable conveyor belt part, while this is pivoted back.

It is the object of the invention to show a device which allows shed stream parts to be extracted from shale streams can be seen, influencing the held funding in the scale flow remaining objects should be largely avoided and where the removal of the scale flow parts should be feasible with a simple device.

This object is achieved by the device and its use as described in the corresponding, independent claims are defined.

According to the device according to the invention, the stream of scale that is conveyed is held funded by a withdrawal area, the funding held for Most of the flake stream parts that should not be removed are preserved remains. For scale flow parts that are to be removed as such or from from which objects are to be removed, the funding held is deactivated, the scale flow parts being released by the holding means in such a way that removal is possible.

The device for carrying out the method according to the invention has Funding for the sustained promotion of a stream of shed (first funding) on. This first funding leads on a first funding path through a removal area, control means for the controlled deactivation of the held funding are arranged. Furthermore, the device points in the removal area a second funding, which at the entrance of the removal area for a Funding arranged on the first funding path (parallel to the first funding) and can be driven synchronously with the first funding and that in the removal area is adjustable either for funding on the first funding path or for one Funding on a second funding path leading away from the first funding path. there the second funding is designed in such a way that it acts on the shingled stream in an area where the holding means of the first conveying means do not act. The second funding is for a loose support or for a held one Funding equipped.

two further removal areas of exemplary embodiments of the device for carrying out the method according to the invention;

Figures 5 to 9

Various exemplary embodiments of clamping members for the device for performing the method according to the invention.

Figures 1 and 2 show very schematically the removal area A of an exemplary embodiment of the device for carrying out the method according to the invention, each as a side view above and as a top view below. The removal area represents a type of switch point, to which the scale flow is conveyed on a first conveying path F.1 and from which the shingle stream parts (2.1, 2.2) are optionally conveyed further on the first conveying path F.1 (FIG. 1) or for removal from the shingle stream can be deflected downwards onto a second conveying path F.2 (FIG. 2).

A first funding 1 serves to maintain the flow of scale 2 the first funding route F.1 to the removal area A and the continued funding of scale parts 2.1 not to be removed on the first conveying path F.1. The first funding 1 consists in the case shown of a transport member 1.1 (e.g. pushed or pulled transport chain or pushed, independent of each other Transport elements) and attached clamping members 1.2 with each a pair of jaws. The clamping members 1.2 are through an input control means 3 can be deactivated selectively (from a clamping configuration to a non-clamping configuration can be brought) and deactivated clamping elements reactivated by an output control means 4 (from a non-jamming Configuration into a jamming configuration).

A second funding means 5 that can be adjusted for removal consists in the illustrated Trap from a series of three conveyor belts 5.1 (on the input side, on the first conveyor path F.1 aligned), 5.2 (adjustable: aligned on the first conveying path F.1 or for removal against the second conveyor path F.2 pivoted) and 5.3 (output side, aligned on the first conveyor path), which are arranged in the removal area A. For the removal of removed shingled stream parts is a removal means 6, for example, another conveyor belt is provided. The conveyor belts 5.1, 5.2 and 5.3 of the second funding 5 are narrower than the scale stream 2 and engage this to promote at its bottom, in an area where it do not come into conflict with the clamping members 1.2 of the first funding 1.

FIG. 1 shows the device during the conveyance of a scale flow part 2.1, which is not removed, on the first funding route F.1. Neither the input control means 3 still the output control means 4 are active, that is, the clamping members 1.2 remain in their pinching when conveying through the removal area A. Configuration. The second funding 5, in particular the pivotable Conveyor belt 5.2 is set to the first conveyor path F.1 and its conveying speed is the same as the conveying speed of the first conveying means 1.

Figure 2 shows the same representation as Figure 1, the promotion of a shingled stream part 2.2 the down for a removal from the first conveyor path F.1 the second funding route F.2 is funded. The clamping members 1.2 are in the area this shed stream part to be removed is deactivated by the input control means, in the present case that means that the pair of jaws for lifting the clamping action is opened (lower jaw moved towards the bottom) and that to release the objects towards the bottom the lower jaws on the side be swung away. The scale flow part 2.2 to be removed is thereby downstream of the input control means only from the second conveying means 5, that is to say loosely supported on the conveyor belts 5.1 and 5.2 and is supported by the Conveyor belt 5.2 swiveled below (set for removal) of the conveyor 6 funded.

The conditions regarding attack on the shingled stream and regarding conveying speed, that apply to the second funding 5, do not apply to the away funding 6. This may very well be wider than and over the stream 2 attack the entire bottom and it can be driven faster or slower be as the first and the second funding (1 and 5) and thereby one removed Compress scale section 2.2 accordingly or pull apart.

How this is done by removing shingled stream parts from a loose overlay Scale flow is also known in a process as described in the Figures 1 and 2 illustrates the scale flow between each to be removed Part and part to be conveyed are separated and are for this separation if necessary, to provide appropriate funds.

The input control means 3 is controlled in such a way that all clamping members 1.2 on scale parts to be removed or on objects containing items to be removed Scale flow parts act, are deactivated by this control means, while other clamping members pass the control means in the activated configuration. At the exit of the removal area A, the clamping members 1.2 by Output control means 4 are brought back into a clamping configuration. Such a reactivation cannot start and end areas of removed scale stream parts are optionally stabilized. The reactivation the clamping members 1.2 at the exit of the removal area provides for that The method according to the invention is not a condition.

The second funding 5 plays on the first in the state of further funding Funding route F.1 (Figure 1) plays an immaterial role. In this condition, this could second funding is also missing. But when it is present and active, it is important that it has the same conveying speed as the first funding 1. On the input conveyor belt 5.1 and / or the output conveyor belt 5.3 can may be omitted if the input control means 3 and the output control means 4 immediately before and after the swiveling conveyor belt 5.2 are arranged.

A removal of scale flow parts downward is shown in FIGS. 1 and 2. In an analogous manner, removal of scale flow parts can also follow can be realized above, the then when deactivating the clamping members upper jaws are to be removed from the area of the shingled stream. withdrawals, in which the second funding path connects straight to the first funding path and the first conveyor path turns down or up are in analog Way too feasible.

FIG. 3 shows a further, exemplary embodiment of the device for Implementation of the method according to the invention, namely as a side view and in a process phase in which a scale flow part to be removed passes through the extraction area A is promoted. Through the removal area A shown leads in turn on the first funding path F.1, the first funding 1 that for a held promotion of the scale flow 2 is equipped with clamping members 1.2. The second funding means 5, which can be adjusted for removal, points to the first one Funding route F. 1 aligned, stationary and synchronized with the first funding 1 operable conveyor belt 5.4 (or other deformable conveyor support) on and an adjustable deflection roller 5.5, which shows a removal position (extended) and designated 5.5) and a rest position (dash-dotted lines and designated 5.5 '). Upstream of the deflection roller 5.5 is the input control means 3 and downstream of it the output control means 4.

For a scale flow part to be removed or for a scale flow part the objects can be seen, the clamping members 1.2 of the first funding deactivated by the input control means and presses the deflection roller 5.5, which is in its removal position, so against the stream of shingles and against that stationary conveyor belt 5.4 that the objects of the scale stream are bent and their leading leading edges from the conveyor 6, which consists of a pair of belts pressed against one another and driven in opposite directions can be.

For the promotion of scale flow parts from which no objects are removed the input control means is not active and is the deflection roller in its rest position (5.5 '), that is, the shingled stream 2 becomes unchanged the funding held on the first funding path F.1 to the withdrawal area A, conveyed through the removal area A and from the removal area A.

FIG. 4 shows a top view of another exemplary embodiment of the device to carry out the method according to the invention. It's a turn again Removal area shown with a first conveyor path F.1 and a second Funding route F.2, with a first funding 1 for sustained promotion of the stream of scale 2 on the first conveyor path F.1 and with an adjustable for removal, second funding 5. The second funding is in this embodiment designed in the same way as the first funding 1, namely as Transport element 5.6 with clamping elements 5.7 arranged thereon. The distances of the Clamping members 5.7 and 1.2 are of the same size and are adapted to the scale flow 2 in such a way that each object of the shingled stream only from one clamping member is held that the stream of shingles is to be understood as a stream of sections , each section comprising a plurality of items and only one Clamping element is held.

The first and the second funding run at the entrance of the removal area A. parallel and synchronous and is an input control means 3 for the first funding provided for deactivating the clamping members 1.2. Upstream of it is a Input control means 3 'for activating the clamping members 5.7 of the second conveying means 5 provided. The first funding 1 leaves the removal area A. on the first conveyor path F. 1, the second on the second conveyor path F.2, the second conveying means 5 also the function of the away conveying means (6 in FIGS to 3) takes over.

To set the second funding for the removal, only that him assigned input control means 3 'active, causing the clamping jaws of the clamping members 5.7 are moved into a clamping position. At the same time it will Input control means 3 of the first conveyor 1 activated and causes the Jaws 1.2 are brought into a non-clamping configuration and that the sections of the stream of shingles to be removed are transferred to the second Funding path are funded.

Upon removal, as shown in Figure 4, scale flow parts taken parallel to the scale flow width. For this reason it is sufficient for Removal to open the clamping members 1.2 of the first conveyor 1. To have to no jaws removed from areas above or below the stream 2 be, as is the case for the process variant that is associated with the figures 1 to 3 have been described, the case is.

The course of the two funds 1 and 5 in a removal area A, as in 4, is arbitrary within wide limits, including the spatial location of the shingled stream. The only condition is an at least selective parallelism at the entrance of the removal area A and the synchronous operation.

If in a removal area, as shown in Figure 4, the first and second funding 1 and 5 are used, with which not every object is held by only one clamping member is another funding, for example to provide a conveyor belt. The clamping members 1.2 of the first funding 1 are then to be deactivated further upstream than the clamping members 5.7 of the second funding 5 are activated, and the shingled stream is between Deactivation and activation by the further funding, for example loose supported on the surface.

Figures 5 to 9 show examples of funding with clamping members and their Application as the first funding 1 for the sustained promotion of scale flows. In all these figures, the line of sight is parallel to the first conveying path directed.

Figures 5 and 6 show a first funding 1 and a second funding 5 in a removal area A. The first funding 1 has a transport member 1.1 is designed, for example, as a pull chain running in a channel 11, and clamping members 1.2 with one stationary jaw 14 and one from the area of Scale stream 2 swiveling clamping jaw 15. The clamping members 1.2 are shown in their deactivated, i.e. non-clamping configuration, in which the The jaw 15 is swung out. The scale stream 2 is thus the second Funded 5 (conveyor belt).

The means shown in Figures 5 and 6 for sustained promotion of a Scale flow and control means for its deactivation / activation are in of publication EP-0095602 described in detail. Of course you can also on Such a funding can be arranged on both sides of the scale stream 2 and the pair of grants serve as the first grants. Of course the funding with clamping members can also serve as a second funding in a process variant, as shown in Figure 4.

FIG. 5 shows an arrangement for removing scale flow parts towards the top, in which the clamping members 1.2 are arranged such that the upper jaws the area of the shingled stream can be swung out. Figure 6 shows an arrangement for the removal of scale flow parts towards the bottom, in which the clamping members 1.2 are arranged such that the lower jaws from the area of Scale flow can be swung out.

Figures 7 and 8 show the same representation as Figures 5 and 6 first Funding with transport organ 1.1 and clamping organs 1.2 in a removal area A. The same parts are identified by the same reference numerals as in FIG. 5 and 6. The clamping members 1.2 shown and control means for their deactivation / activation are described in detail in publication WO-99/30997.

7 has two from the area of the scale flow swing-out jaws 15 and is therefore suitable for arrangements with removal areas in which scale flow parts down and / or be deflected upwards.

FIG. 9 shows a first one again in the same representation as FIGS. 5 and 6 Funding 1 and a second funding 5 in a removal area A. The first Funding means 1 has clamping members acting on both sides of the scale stream 2 1.2 on with lower jaws which can be swung out from the area of the scale flow 15. The second funding 5 is in turn designed as a conveyor belt. The Clamping devices 1.2 and control means for their deactivation / activation are in the Publication CH-559692 described in detail.
