Abstract

In a method and device for the automatic insertion of cores in roller die-cutters of the support cylinder type, a wide web (12) of paper or the like is unwound from a wide roll (11) at an unwinding station (10). In a cutting station (20), this wide strip (12) is divided lengthwise into at least two narrower partial strips (24). In two winding stations (40, 50) each arranged on one side of the backing roll(s) (30) and each consisting of at least one winder (41, 51), the narrower partial strips (24) are wound with the use of mandrels (44, 54) in such a way that each adjacent partial strip (24) is wound on different winding stations (40 or 50). In an insertion device (60), the mandrels (44, 54) are successively slid, depending on the winders (41, 51) to be equipped, into a receiving position parallel to the support cylinder (30) or to the cylinders support, distributed on both sides of the support roller(s) from their reception position and transported into a position for tensioning the winders (41, 51) to be tensioned there in order to then receive the corresponding partial strip. The mandrels (44, 54) located in their receiving position and distributed on both sides of the support roll(s) are picked up by the transport device (70) associated with each winder (41, 51) and raised or lowered in tension position along an essentially straight path. In this way, the automatic insertion of the mandrels is significantly improved, since the use of mechanical devices is relatively low, despite the elimination of major adjustment work, a reduction in preparation times and savings in maintenance personnel.

Description

 Method and device for automatic tube feeding in roll cutting machine of the backup roller type

The invention relates to a method for the automatic feeding of winding cores into a roll cutting machine of the support roller type according to the generic features of claim 1 and a roll cutting machine for performing this method.

In the case of roll cutting machines of the back-up roll type, the winding devices are often so-called center winders, because the clamping heads receiving the winding sleeves for receiving the ends of the partial webs to be wound are driven in the winding direction. These known roll cutting machines deliver good winding results and have been used in industry for many years. The production capacity of these machines is severely limited by the time and effort involved in changing the roll / winding tube. This procedure lasts between five and eight minutes and requires up to four to five workers for a roll cutting machine with a corresponding number of stations. The average cutting and winding time is approximately 12 minutes. This means that the machine does not produce for 30 to 40% of the time (DE 38 00 703 AI).

Both for roll cutting machines with a back-up roll and for those with two back-up rolls, the web being fed from below into the winding station, it is known to feed the winding tubes from above the back-up roll (s) automated form. For this purpose, according to DE 38 00 702 AI, a feed bar is provided for each of the two winding stations arranged on the side of the support roller (s). watch that extend over the entire width of the machine, which can be eight to ten meters, and are carried on the front of the machine by swivel arms. Both feed bars each have a trough for receiving the winding tubes. When the two feed bars are swiveled towards each other and stand close to one another, the two channels lie so close to one another that there is only space for a single winding tube in each length section of the feed bar. As a result, the winding sleeves, which have already been cut to length, can be placed alternately from one end of the feed bar onto the trough of one or the other feed bar and pushed in their entirety along the two troughs into the transfer positions corresponding to the positions of the winding device by means of a slide. The winding sleeves are thus divided into the two channels belonging to one of the winding stations as soon as they are pushed into the channels. In this case, a reliable division is difficult. In order to equip the individual winding devices with new winding sleeves, the feed bars must be pivoted on a circular arc in the direction of the pairs of support arms of the winding devices. During this swiveling process, the winding tubes roll in the gutter receiving them from a first to a second stable position, where they are prevented from rolling out of the gutter by a stop which in turn is pivotable. The stoppers are pivotally attached to the feed bar under spring force, so that the stopper plate located in the area of the support arms of the winding devices can yield to the support arms. This known feeding device has three disadvantages in particular: first, there is the risk that when the winding tubes roll from one to the other the stable position (momentum) of the rolling winding tubes becomes so great that the surface-rounded stopper plate does not stop this rolling movement can. This danger exists especially in the case of winding cores with a relatively large diameter and / or a relatively large weight. Secondly, the adjustment of the winding sleeves in relation to the clamping heads of the winding devices is particularly complex when the winding sleeve diameter is to be changed and / or even Sleeves of different diameters are to be wound during a single winding operation. After all, it is difficult to move the winding cores exactly on their different positions in their transfer positions.

A certain simplification of the winding tube feed has been proposed in DE 37 37 503 AI for a reel cutting machine with two support rollers. With this machine, all the winding cores required for a winding process are pushed onto a single channel. The winding sleeves are not divided into the sides corresponding to the two winding stations until the winding sleeves are in their transfer positions corresponding to the winding devices. The division takes place by unfolding the channel downwards and transferring the winding tubes to mutually attached gripping arms which pull the winding tubes to the correct side and lay them down on an inclined plane which leads to the clamping position of the corresponding winding tube. In this known winding tube feed device, too, a stopper is required which prevents the winding tube from rolling further and stops it exactly in the clamping position. This known winding tube feed device requires a relatively large number of movable parts. In addition, the adjustment effort when changing the part web widths and / or the winding tube diameter is considerable. Finally, when changing the width of the partial web, the gripper arms must independently, i. H. readjusted separately from the winding devices. For this purpose, a box girder that extends across the entire width of the machine with side guide rails and slides that can be moved thereon must be provided.

Proceeding from this, the object of the invention is to create a method and a device of the type mentioned at the outset by which the automatic winding tube feed to the winding devices is simplified. To solve this problem, the method with the features of claim 1 and proposed the device with the features of claim 2.

The invention u. a. accomplished that

- The centering of the winding tubes on the Spannkσpfmitteπ as well as the winding tube transport from the transfer to the clamping position can be done precisely and quickly;

- The stopping point of the transport device in the clamping position can be adjusted simply and precisely, in particular programmably, so that sleeves with different diameters can be processed without problems, d. H. Both different sleeves on different winding devices and - fundamentally - different sleeves from winding operation to winding operation on the same winding device, this operation being able to run fully automatically.

The transport devices according to the invention can be used both in reel cutting machines with a single back-up roll and in reel cutting machines with two back-up rolls; Likewise, the partial webs can be fed to the support rolls both from below and from above. The rectilinear movement according to the invention, which is a lifting or lowering movement, does not have to be vertical, but can also be carried out obliquely, ie with a clear horizontal component; this is regularly necessary when the winding tubes are fed in a position above the one or both support rollers, that is to say that the partial webs are then usually fed to the support roller (s) from below. In these cases, the winding sleeves must be lowered from the transfer position into the clamping position by the transport devices. If, on the other hand, as is preferred (claim 3), the feed device for the winding sleeves is arranged below the, preferably single, or below the two support rollers, the winding sleeves are lifted from the transfer position into the clamping position by the transport devices and the angle of inclination can be adjusted the linear transport movement be kept small with respect to the preferred, pure vertical movement; Both measures (lifting and small angle of inclination) are advantageous for a calm and secure position of the winding tubes in the receiving elements on the transport devices.

It is essential for the invention that the transport devices consist of lifting or lowering devices, ie. H. from such transport devices which carry out a straight-line movement sequence, as is the case with the preferred piston / cylinder arrangements, spindle drives, linear motors and similar straight-line working sports devices. According to the invention, it is preferred that the transport movement takes place only in a straight line, ie. H. that the angular position of the transport devices with respect to the vertical direction remains constant during the entire lifting or lowering process. In principle, however, it is also possible to superimpose a certain pivoting movement of the transport device on the lifting or lowering movement.

Each of the winding devices of a slitter-winder is preferably assigned a specific transport device, it being particularly preferred that the winding device and the transport devices assigned to it are always movable together (claim 8). It is fundamentally possible to provide only a single lifting or lowering element for each transport device; it is preferred, however, that each side of each winding device, ie in particular each support arm, is assigned its own transport device, in particular is arranged to be movable together with it; then a transport device consists of two lifting or lowering devices arranged spatially separated from each other. In this case, when changing the partial web widths, there is no need to move and / or readjust the transport directions separately; Likewise, with such a facility - as will be explained further below - the process of taking over the Winding sleeves can be carried out particularly simply, that is with little effort and precisely, by the receiving elements of the lifting or lowering elements.

In principle, however, it is also conceivable for each winding station, ie. H. to provide only a single pair of lifting or lowering elements on each side of the support roller (s), and to arrange all of the receiving organs for the winding cores provided for the relevant machine side on a traverse moved jointly by the two lifting / lowering elements without the basic idea to leave the invention.

Under "gutters" for jointly receiving all of the winding tubes required for the unwinding devices of both winding stations, d. H. for the inclusion of a complete set of winding cores are, within the meaning of the invention, actual trays and gutter-like holding devices to be understood, which make it possible to accommodate all the winding cores of a set one after the other in their axial direction, in particular in such a way that the winding cores of one end of the machine can be pushed onto this "gutter" as it is e.g. B. is known from DE 38 00 702 AI. Such a channel is preferably - in contrast to DE 38 00 702 AI, where a double channel is provided - but "single-track", ie. that is, the axes of all the winding cores lie on a common straight line or, if the winding cores have different diameters, the winding cores are located in a common vertical plane; this is already the case with the "gutter" known from DE 37 37 503 A1 and has the advantage that when the winding tube is pushed into the "gutter" from one end of the machine, there is still no subdivision on the two sides of the machine, ie. H. on the two winding stations, as required by DE 38 00 702 AI.

The take-over of the winding tubes from the "groove" by the receiving elements of the lifting / lowering elements is now preferably carried out ( Claim 4) in that the winding tube receptacles of the individual transport devices in their winding tube receiving position are arranged laterally of the channel in such a way that they "catch" the "dropped" winding tubes. The "dropping" of the winding tubes on the "groove" is already known from DE 37 37 503 AI and includes that the winding tubes z. B at least one inclined plane is fed to each side of the machine, over which they roll due to their gravity, where they lose height and that the sleeves assigned to the two winding stations attain lateral spacing from one another. The "catching" of these winding cores by the receiving elements according to the invention therefore means that the winding cores, which move freely after the division into the two machine sides, return to a defined position.

There are now various possibilities for designing the means for throwing off the winding tubes. The alternative embodiments according to claims 5 or 6 are preferred. In both cases, which can also be used sensibly and advantageously independently of the features of claims 1 and 2, only a single channel is required to accommodate an entire set of winding tubes. In the embodiment according to claim 5, at least one lifting element is required for each winding tube, while in the embodiment according to claim 6, at least one retaining element, preferably two retaining elements, which are preferably designed according to claim 7, should be provided for each winding tube. The organs for "ejecting" the winding cores from the "groove" therefore also divide the winding cores over the two sides of the machine, ie over the associated winding stations. In principle, however, it is also conceivable for the lifting / lowering elements according to the invention to divide the winding cores over the two sides of the machine. This would be e.g. B. possible in that the receiving members of the lifting / lowering members are moved exactly or roughly into the positions of the winding sleeve, in which the winding sleeves are located in the "groove" in order to directly, there, the respective winding sleeve. B. by lifting the Take over the winding tube from the gutter. In such a case, a pivoting process of the lifting / lowering elements, in particular about their base point, could pivot them into the angular position (relative to the vertical direction) that corresponds to the angular position for the transfer of the winding tubes into their clamping position; in particular, all lifting / lowering elements of one machine side could be pivoted together, while the lifting / lowering movement of each transport device and possibly also a method transverse to the direction of movement of the partial webs could be carried out separately, in particular programmed, for each lifting / lowering element.

The size, shape, material selection and technical conception or process conditions of the above-mentioned components as well as those claimed and described in the exemplary embodiments and to be used according to the invention are not subject to any special exceptional conditions, so that the selection criteria known in the respective field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention will become apparent from the following description of the accompanying drawing, in which — by way of example — two preferred embodiments of a winding tube feed device according to the invention are shown. The drawing shows:

1 of a reel cutting machine, the rewinder in frontal view (view A according to FIG. 8) and - schematically and on a smaller scale - the other assemblies of the reel cutting machine;

2 to 7 show a sequence of the working cycle of the winding tube feed and the partial web winding in a schematic representation and otherwise in the same view as in FIG. 1; 8 to 10 of the roll cutting machine according to FIGS. 1 to 7 with the back-up roll and roll cutting station omitted in a view from above (corresponding to the view in the direction of the arrows BB according to FIG. 6) a sequence of the winding tube transfer from the Channel to the lifting / lowering elements;

11 to 16 for a roll cutting machine as in FIG. 1, an alternative embodiment of the winding tube feed device in the same view as in FIGS. 1 to 7 as a sequence of a winding tube feed cycle.

In the roll cutting machine according to FIG. 1, 10 as a whole denotes an unwinding station for at least one wide roll 11 of a web 12 of paper or the like. The unwound, but still undivided web 12 becomes a cutting station designated as a whole with 20, which u. a. a plurality of rolls x) 21, 22, ... has at least one longitudinal cutting device 23 and other known organs.

The partial webs 24,... Created in the cutting station 20 by longitudinal division of the web 12 are fed to a support roller 30 which extends over the entire machine width and which, if appropriate, can have a vacuum suction facility for holding partial web ends.

On each side of the (at least) one support roller 30 there is a winding station 40, 50, each of which consists of at least one, preferably a plurality of winding devices 41, 51.

Each winding device 41 and 51 consists (in the core) of a pair of support arms 42 and 52, which are provided with clamping devices 43 and 53 at their free ends. The clamping devices 43 and 53 can engage in tubular winding sleeves 44 and 54 from the ends of the winding sleeves, are non-rotatably braced with the winding sleeves and driven in the direction of rotation (center winders) - see also FIGS. 7 to 10. x) (rollers) The support arms 42 and 52 are pivotally mounted in their lower end regions about axes 45, 55. The pivoting path of the winding axis is shown as a dash-dotted line 46 or 56.

The pivoting action of the support arms 42 and 52 takes place by means of piston / cylinder devices 47 and 57, which in turn are pivotably mounted about axes 48 and 58, respectively. The pivot bearings for the axes 45 and 48 or 55 and 58 are each located on a common support member 49 or 59, with which each of the previously described assemblies 41 ', 41 ", 51', 51" forming one half of a winding device as a whole and independent of the other corresponding modules along the machine width, d. H. can be moved along the at least one support roller 30, so that partial webs of different widths can be wound up to partial web rolls 25. The support roller 30 is supported by a frame formed from sections 31 shown in detail and a crossbeam not shown. The components described above are known per se in the case of roll cutting machines and therefore do not require any further detailed explanation.

All of the winding sleeves 44 and 54 forming a set, which are required for a winding operation, are fed to the winding machine and there to the individual winding devices 41 and 51 via a feed device 60 which is known with regard to their general function. For this purpose, an elongated support element designated as a channel 61 is provided, which extends over the entire machine width below the support roller 30 and parallel to it. The winding sleeves 44 and 54 can be pushed onto the trough 61 from an end of the machine through an opening 32 in one of the supports 31. There are known means for this process, such as. B. according to DE 38 00 702 AI. The feed device 60 furthermore consists of training devices 70 which take over the winding cores 44 and 54 from the trough 61 and move in a straight line into the clamping position (shown on the left in FIG. 1), ie the position of the clamping devices 53 shown there . The transport devices 70 are lifting / locking elements with a - in the exemplary embodiment, double-armed receiving element 71, which is attached to the upper end of each lifting / locking element and a positionally accurate mounting and storage during transport into the clamping position enables along the dash-dotted line 72. 1, the winding station 50 is shown in the tensioning position and the winding station 40 in the winding position. As a rule, however, all the winding devices are in the same working position.

The training devices 70 can e.g. B. as an electro-mechanical lifting cylinder - with or without drive 70 '- configured. Such lifting / lowering organs are available in various forms on the market and are therefore to be regarded as known, so that they require no further explanation. They allow u. a. an exact method in end positions which can be set by means of pre-programming. The alignment of the transport devices to the clamping positions only needs to be carried out once if adjustable holding means 73 are provided, which allow the transport devices to be fixed in a specific direction and these holding devices 73 are attached to the associated support device 49 or 59 of the respective one Winding half can be fastened.

The winding sleeves 44 and 54 are transferred from the trough 61 to the receiving members 71 by "throwing" out of the trough 61 and "catching" by the receiving members 71. For this purpose, the trough 61 is pivoted about an axis 62 about its longitudinal direction, wherein the pivoting movement to one or the other side of the rim is carried out by means of at least one pivoting device 63. As a result, the trough 61 can be as far as one or the other the other side are pivoted so that the winding sleeves 44 and 54 laterally roll out of the trough 61 and reach the receiving organs 71 directly via inclined planes 64. Retaining organs 65 prevent the winding cores 54 and 44 intended for the respectively opposite winding station 50 or 40 from getting into the wrong winding station.

The structural details and sequences of movements result from the following description of a complete working cycle of the rewinding device with reference to FIGS. 2 to 10 and - for an alternative embodiment - with reference to FIGS. 11 to 16:

FIG. 2 shows the work phase in which the partial web rolls 25 are located shortly before their completion. The winding sleeves 44 and 54 provided for the next rewinding process are already in the channel 61 of the feed device 60. These winding sleeves have different diameters, while the two recognizable partial web rolls 25 are wound on winding sleeves of identical diameter, with underlying and therefore not recognizable Part web rolls can of course also be equipped with winding cores of different diameters.

From Fig. 3 it can be seen how the partial web rolls 25 have been placed on the floor 33 by pivoting the support arms 42 and 52 after completion of a rewinding process. The partial webs are then cut so that the partial web rolls 25 can be transported away and the next winding process can be prepared. However, this is not shown in detail since it is not part of the subject matter of the invention and - in principle - is already known.

After the partial web rolls 25 have been placed on the floor 33, the tensioning devices 43 and 53 of the winding devices gene 41 and 51 are still relaxed and removed from the winding tubes in the axial direction. This happens e.g. B. in the working phase shown in Fig. 3 and can - in principle - also take place later. The point in time at which the finished partial web rolls 25 are laterally rolled out of the winding stations 40 and 50 is essentially independent of this. 5 shows the situation after rolling out. The support arms 42 and 52 then move into the clamping position shown in FIG. 6 (and in the left half of the figure in FIG. 1), in which the new winding tubes are to be clamped into the respective winding device.

In the meantime, the process runs - largely independently of the work processes of rewinding partial webs, severing the partial webs, depositing the partial web rolls, removing the tensioning devices and removing the finished partial web rolls, as well as swiveling the support arms back into the tensioned position feeding a new set of bobbins. This is described below:

First, as already mentioned, a complete set of winding tubes is introduced into the channel 61. For this purpose, the winding tubes are preferably already cut to length and are pushed into the channel 61 from one end of the machine, sorted according to diameter and length. Then the winding sleeves have to be pushed into the take-over position, ie the position in which the winding devices 41 and 51 are to take over the winding sleeves 44 and 54 later. If the widths of the desired partial web rolls are sufficiently large, the winding tubes located one behind the other in the trough can abut one another. However, are the desired partial web widths so narrow that it is no longer possible to move the tensioning devices 43 and 53 on both sides apart sufficiently because then the assemblies 41 ', 41 "or 51', 51" of adjacent winding devices If there were collisions with one another, it is particularly advantageous to move the winding-up devices of each winding-up station apart along the extension of the at least one support roller 30 after the partial webs have been cut off. This creates a sufficient lateral distance for the subsequent moving apart of the associated assemblies 41 'and 41 "or 51' and 51" and for taking over the new winding sleeves 44 and 54. This transfer position is shown in FIGS. 8 to 10. This, preferred, procedure requires the winding sleeves 44 and 54 to be initially positioned at an axial distance from one another (FIG. 8) and, after taking over and clamping these new winding sleeves, the winding devices 41 and 51 of each winding station must be moved towards each other again in such a way that between the adjacent partial webs 24 or partial web rollers 25 do not have any spacing gaps in the axial direction.

The process of this sleeve positioning can be automated with sliders or the like which are known per se and are therefore not specifically shown in the drawing.

From the sequence of FIGS. 3 to 5, which correspond to the sequence of FIGS. 8 to 10, it can now be seen how the process of "dropping" the winding cores out of the trough 61 and "catching" the winding cores by the receiving members 71 takes place :

First, all the winding sleeves 44 and 54 rest in the single groove 61 in the takeover positions shown in FIG. 8. If - as preferred - and as can be seen in FIGS. 1 and 8 to 10 ^" , the transport devices 70, the inclined planes 64 and the retaining members 65 of each assembly 41 ', 41" are firmly connected to it and can be moved laterally with it the "ejection" from the trough 61 does not take place until the aforementioned assemblies are in their takeover position, as shown in FIGS. 8 to 10. If, as can be seen from FIG. 4 (corresponding to FIG. 9), the channel 61 is pivoted to the winding station 50 (shown on the left in the picture), the winding sleeves 54 provided for this winding station roll over the oblique ones assigned to the assemblies 51 'and 51 " Levels 64 directly into the receiving members 71 of this winding station, while the winding sleeves 44 intended for the winding station 40 are retained by the retaining members 65 of the assemblies 51 'and 51 "in such a way that they remain in or in when the channel 61 is swung back these come back so that they can subsequently be “thrown” onto the other side — towards the winding station 40. For this purpose, the retaining members 65 can have curved stop surfaces 66.

During this “throwing off process” and “catching process”, the carrying arms 42 and 52 can still be in a position other than the clamping position (see FIGS. 4 and 5). In order to take over the winding cores from the transport devices 70 through the clamping devices 43 and 53, the support arms 42 and 52 must be pivoted into the clamping position shown in FIGS. 6 and 15, respectively. Because the curved lines of movement of the winding axes of the support arms 42, 52 are cut in the clamping position by the straight lines of movement of the winding tube axes, the transport devices only need to stop at predetermined points, so that tubes of different thicknesses are centered precisely in the tensioning position can be driven. This is followed by the tensioning process, possibly the lateral movement of the winding devices into the required winding position and the approach of the new winding sleeves 44 and 54 to the support roller 30, where they come to rest and are connected to the associated partial web in a manner known per se , so that the next winding process can begin (Fig. 7).

In the embodiment according to FIGS. 11 to 16, the main difference to the aforementioned embodiment (according to FIGS. 1 to 10) is that the channel 61 does not extend around its longitudinal Axis is pivoted, but that, in each case to the side of the center of the gutter, along the gutter 61, a plurality of small lifting members 67 are provided, which with z. B. fluidically or magnetically driven plungers 68 are able to laterally raise the winding tube 44 or 54 lying in the respective longitudinal section of the channel so that the winding tube in question has one of the lateral top dead centers 69 formed by the channel 61 'or 69 "are raised.

The work situation in FIG. 11 roughly corresponds to that of FIG. 2.

FIG. 12 corresponds - analogously - to FIG. 3.

14 corresponds - analogously - to FIGS. 4 and 5.

FIG. 15 corresponds - analogously - to FIG. 6, but with the difference that in FIG. 15 the tensioning position coincides with the winding position (corresponding to FIG. 7). For the sake of completeness, FIG. 16 also shows how the transport devices moved back into the take-over position at the start of the winding process.

According to FIG. 13, a further special feature is provided in this exemplary embodiment: the inclined planes 64 are assigned to the assembly containing the channel 61 and not - as is the case according to FIGS. 1 to 10 - to the individual assemblies of the winding devices. The inclined planes 64 are formed by plate-shaped elements which are arranged one behind the other in the machine direction (parallel to the support roller axis) with more or less small distances and whose length is less than half the width of the minimally expected part web width. These plates 64 'can be pivoted about an axis 64 "in the direction of the arrows shown in FIG. 13, so that they can be pivoted at least when they are in the position of the support arms 42 or 52.
