Description

Roll Cutters

The invention relates to a roller plotter and a method for processing a sheet with this roller plotter according to the preamble of claims 1 and 10.

Roll plotters are used for editing flexible

textile or non-textile fabrics used. In this case, the fabric is moved by means of a cylindrical transport drum in a conveying direction and processed by means of at least one tool. Examples of such tools are in particular cutting devices with a cold knife or an ultrasonic knife. Other tools are e.g. Welding devices, in particular ultrasonic welding devices, which are designed to connect two layers of the fabric locally by supplying energy.

Roll plotters can be used in particular for editing

large area sheet such. Awning cloths or tarpaulins are used in the roll-to-roll process. Compared to flatbed plotters, where the sheet rests on a flat work surface during processing, roller plotters are compact and space efficient. Therefore, with roller plotters and large-area fabrics on relatively narrow

Room to be edited. Another advantage of roller plotters is that certain processing steps such as cutting of longitudinal edges in the conveying direction during transport of the fabric can take place. The productivity and efficiency of role plotters are therefore comparatively high.

For processing a fabric with a tool transversely to the conveying direction, this tool can e.g. be moved along a guide rail transversely to the conveying direction. The conveying speeds of the fabric in the conveying direction and the tool must be transverse to the conveying direction according to a predetermined

Machining contour to be coordinated. if the

Processing should be orthogonal to the conveying direction, for example, for separating a portion of the

Sheet, the sheet may not be moved in the conveying direction.

By reducing the conveying speed or the standstill of the fabric during processing with the tool transversely to the conveying direction also reduces the efficiency of machining.

If the sheet is being processed simultaneously with at least two tools, the modification of the

Conveying speed has a negative impact on the

Quality of the processing of the fabric with a or more of these tools. If the other tool eg for cutting and sealing the

Sheet is formed by energy supply, in particular along a longitudinal edge in the conveying direction can, for. a locally too high energy intake will decrease the quality of the seal or the affected one

Even destroying edge section.

From EP 0276027 an apparatus for cutting writing and characters in sheet material is known. In this case, the sheet together with a chuck, to which the sheet is glued, is moved by a transport drum in a first direction relative to a cutting tool. This first direction is orthogonal to the axis of rotation of the transport drum and corresponds to the direction of

Tangential speed of the transport drum at the processing point by the cutting tool.

The cutting tool is mounted on a carriage which is movable in a second direction orthogonal to the first direction. The transport drum and the carriage can be controlled by a controller simultaneously. This makes it possible to cut the sheet according to stored sectional contours, which have both components in the first direction and in the second direction. The conveying speed of the transport drum is adjusted according to the contour to be cut. For cutting orthogonal to the conveying direction must

Rotary movement of the transport drum are stopped.

The cutting tool, e.g. a knife may additionally be rotated about an axis of rotation that is orthogonal to the first and second directions. The knife can be aligned during cutting according to the respective cutting direction. This is also called a tangential knife.

An object of the present invention is to provide a roller plotter which enables efficient processing of fabrics with at least one tool

allows. Another task of the present

The invention is to provide a method for efficiently processing a sheet with such a roll plotter.

These objects are achieved by a roller plotter and by a method for processing a sheet with this plotter according to the features of

Claims 1 and 10.

The roller plotter comprises a transport drum, which is mounted rotatably about a drive axis on a machine frame, and with which a sheet can be transported in a conveying direction. The

The conveying direction is always orthogonal to the drive axis. at flexible and / or pliable fabrics, the conveying direction may have locally different directional components in the respective normal plane to the drive axis. This is particularly true when a portion of a sheet is wound around a portion of the lateral surface of the transport drum or rests against this.

The term "in the conveying direction" usually means "in or against the direction of conveyance", unless explicitly stated in another sense.

A guide rail is arranged parallel to the transport drum. The guide rail serves as a carrier on which at least one carriage with at least one tool can be moved transversely to the conveying direction. The guide rail can be moved around the transport drum at least within a movement sector. It is preferably mounted by means of two pivoting arms coaxially to the transport drum pivotally mounted on the machine frame.

A conveyor drive the transport drum, a

Rail drive, with which the guide rail around the

Transport drum is movable around, as well as a

Carriage drive, with which the at least one carriage is movable transversely to the conveying direction, are controlled by a common control.

When processing a sheet, the

Motors of these drives so controlled that the Sheet can be edited with the tool along a predetermined contour. The required information such as data describing the geometry of the machining contour and / or data from

Speed profiles of the drive motors are suitably stored in a memory.

In particular, for a sequence of points along the contour, e.g. the associated coordinate values in

Transport direction and be stored transversely to the conveying direction. These coordinate values can be e.g. as absolute values with respect to a reference position and / or relative values with respect to coordinates of one of

preceding points, in particular the immediately preceding point in the sequence of points. The sheet and the respective tool are positioned relative to each other prior to machining so that the position of the tool coincides with a reference point of the sheet. Thereafter, the sheet is processed according to the stored data from the reference position.

Additionally or alternatively, any contour along which the sheet is using a particular tool

be edited, be given by speed profiles of drive motors. Each speed profile defines the speed or speed of each of the motors in

Dependence of time. The relative speed between the respective tool and the one to be machined

Sheets are defined by the velocity profiles of those engines that support the tool and / or the tool

Moving fabrics. The relative movement of the tool and of the sheet comprises the following components of motion: a) movement of the sheet in or against the sheet

Conveying direction by a conveyor motor. This movement corresponds to the surface speed of the

Transport drum at the processing station,

b) movement of the guide rail in or against the

Conveying direction around the transport drum around by a rail motor,

c) Movement of the carriage, which carries the tool, along the guide rail transversely to the conveying direction through the carriage motor.

The relative movement of tool and sheet in or against the conveying direction results from the

Overlay or the difference of the speed proportions of the sheet and the tool in

Conveying direction. It is essentially through the

Speeds or speeds of the conveyor motor and the

Rail engine determined. With the same sign of both velocity components, the resulting velocity value decreases, with different sign it increases. When machining a fabric with one or more tools, the control of the motors takes place according to the specifications of a stored control program. Preferably, optimized speed profiles for the motors required during machining are stored in a memory accessible to the controller.

Optimized speed profiles ensure efficient processing of the fabric with one or more tools, taking into account quality specifications. The speed profiles of the involved

Engines are set so that the machining of the

Sheet with each tool involved along the given for this tool contour under

Taking into account further parameters or conditions in the shortest possible time, and that the processing of the fabric with each tool involved

meets minimum specified quality requirements.

Such parameters or conditions to be considered are in particular

a) usable speed ranges or maximum speeds of the motors and b) for each tool depending on one or more parameters predetermined maximum Bearbeitungsgeschwindig speeds at which the desired quality of processing is ensured. Such parameters are eg type of tool; Type of fabric; Machining contour, in particular coordinates of points along the

Machining contour and / or directions and / or

Radii of curvature at points along the machining contour; Position of the tool relative to the sheet (position and / or orientation); Pressure force and / or power or energy input of the tool into the fabric.

The values of the maximum processing speeds or the maximum permissible relative speeds between a tool and the fabric and / or their

Portions in the conveying direction and transversely thereto may e.g. be given as functions in dependence of one or more such parameters. Such functions may e.g. be defined by function values at several nodes, where these nodes by values of one of

Parameters or combinations of values of several parameters. For parameter values between these interpolation points, functional values may e.g. by

Interpolation be determined.

Preferably, in a memory of the controller

Tool-specific data from applicable tools such as For example, the maximum allowable relative speed stored in the processing of one or more types of fabrics. Alternatively, such data may be for one

Be stored reference sheet. For other types of fabrics, data of the reference sheet may be stored, for example, by stored

Correction factors or correction values are adjusted.

Preferably, the controller comprises a calculation module which is designed to calculate optimized speed profiles for controlling all required motors from stored contour data. It can be used for the processing of the fabric in compliance with

Constraints required time, e.g. by means of

Algorithms of variational calculus are minimized.

Secondary conditions are in particular values and functions which limit the usable maximum speed of at least one of the motors.

This calculation of velocity profiles may be e.g. in an initialization process before starting to process a sheet. Alternatively, the

Control also be designed to

Speed profiles while editing the

Calculate sheet. In particular, you can

Velocity profiles e.g. for given

Time intervals are calculated continuously during the processing of a fabric. A minimization of the processing time can be achieved in particular by maximizing the conveying speed or the average speed of the transport drum and / or by simultaneously processing the sheet with a plurality of tools. This ensures a high efficiency in the processing of the fabric. In tools which are arranged on a pivotable about the transport drum guide rail, the component of the relative velocity in the conveying direction is composed of the proportion with which the

Transport drum promotes the fabric and the

Share with which the tool in or against the

Conveying direction is moved. The relative movement of the

Tool and the fabric in the conveying direction can thus be effected by two independently controllable motors. In particular, the controller can control the rail drive coordinated with the rotational movement of the transport drum so that the tool moves in the conveying direction as fast as that

Sheets themselves. A treatment of the

Flat fabric transverse to the conveying direction is thus possible even if the fabric at the same time in

Transport direction is transported. As a rule, no reduction of the conveying speed is required. The relative speed in the conveying direction is zero when the rotational speed with which the guide rail is moved around with the tool around the transport drum, and the rotational speed of the transport drum have the same direction of rotation and amount to match.

By simultaneously moving the guide rail and

Turning the transport drum may be for tools on the guide rail one of the conveying speed

Deviating relative speed can be specified in the conveying direction. This is particularly advantageous if no or only a small relative speed in the conveying direction is possible for the processing of a sheet with a tool transversely to the conveying direction, otherwise the processing speed would be too high transverse to the conveying direction. In this case, the

Speed of the transport drum is not or only slightly reduced. Simultaneous editing of the

Sheet with other tools, e.g. are arranged on another guide rail is still possible.

On the pivotable guide rail, e.g. on

at least one transverse to the conveying direction carriage be arranged a cutting blade. With this

Tool can be a sheet during transport in Be separated along a cut line orthogonal to the conveying direction conveying direction.

Alternatively or additionally, e.g. at least one transverse to the conveying direction carriage a

Ultrasonic sonotrode or another tool may be arranged. With this tool, a sheet can be processed without significant reduction of the conveying speed along contour sections, the one

lower relative speed in the conveying direction

require.

In particular, the sheet without changing the direction of rotation of the transport drum along along

Contour sections are processed, which are aligned opposite to the conveying direction. The share of

Relative speed in the conveying direction is negative in these contour sections.

The pivoting of the guide rail can be used not only during the processing of a sheet. Preferably, the guide rail can also be pivoted to a maintenance position, e.g. allows easy attachment and removal of tools.

The invention will be explained in more detail below with reference to some figures. Show Figure 1 is a simplified representation of a

Roll plotter in a front view,

Figure 2 is a simplified cross-section of a

Rollenplotters, with a swivel arm with

Tools are shown in different pivotal positions,

FIG. 3 shows a cross-section of the roller plotter in FIG

Area of a swivel arm

Figure 4 shows a sheet with machining contours.

The roller plotter shown by way of example in FIG. 1 comprises an electronic control 1 and a transport drum 3 controlled by the control 1, which

horizontally lying on two mutually opposite bearings of a machine frame 5 is rotatably mounted about a drive axis Al, and which is intended for conveying a fabric to be machined 13. In each of these bearings, so in the region of the two ends of the transport drum 3, a respective pivot arm 10 is mounted coaxially to the transport drum 3 about the drive axis Al pivotally mounted on the machine frame 5. Each of the pivot arms 10 comprises a leg which projects radially beyond the transport drum 3. A guide rail 7 extends spaced and parallel to the transport drum 3 between the two legs of the pivot arms 10. The two ends of the guide rail 7 are connected to the legs of the pivot arms 10. The guide rail 7 can be at a constant distance from Transport drum 3 are pivoted about the drive axis Al.

Preferably, the guide rail 7 is additionally mounted pivotably about a parallel to the drive axis Al aligned rail axis A2 on the pivot arms 10 so that they can take at least two different pivot positions. Such pivotal positions are e.g. at least one

Working pivotal position for machining a fabric 7 with a tool 21 arranged on the guide rail 7 and / or a maintenance pivoting position, which is e.g. for easier attachment and / or removal of a

Tool can be used. The rail axis A2 may be e.g. be arranged in cross section within the guide rail 7 and / or in the region of the center of mass of the guide rail. 7

Additionally or alternatively, the pivot arms 10 guides for at the ends of the guide rail. 7

arranged slide 7a include. This allows a guided displacement of the guide rail 7 along the legs of the pivot arms 10 and thus radially with respect to the transport drum 3. As a result, the distance between the transport drum 3 and the guide rail 7 can be changed. The guide rail 7 always remains parallel to the transport drum 3 aligned. One or more carriages 9 are on the guide rail 7 in the direction of the rail axis A2, ie parallel to

Transport drum 3 and transversely to the conveying direction of a processed sheet 13, guided slidably guided.

At least one tool 21 by means of a tool holder 19 is preferably detachably or exchangeably attached to each carriage 9.

The alignment of the tools 21 at the respective

Tool holder 19 and / or the tool holder 19 on the respective carriage 9 may be fixed.

Preferably, however, the tools 21 or the tool holders 19 are rotatably mounted about an associated axis of rotation A3, A3 '. This axis of rotation A3, A3 'is preferably

aligned orthogonally to the rail axis A2 or

alignable.

Figure 2 shows a cross section of a part of such a roller plotter, the arrangement in a first

Swivel position of the swing arm 10 is shown by solid lines and in a second pivot position by dotted lines. In the second pivotal position are the

Reference number supplemented by an apostrophe (').

In the lower front region, a supply roll 11 of a sheet 13 is rotatably mounted. The conveying direction of the sheet 13 is represented by arrows PI.

A front strip section of the fabric 13 is guided around the transport drum 3 from below in such a way that it wraps around it over an angular range of preferably more than 180 °. As a result, a precise, slip-free conveying of the fabric 13 is favored. This can be ensured for example by means of guide drums 15a, 15b, the input side and

on the output side adjacent to the transport drum 3 or at a small distance parallel to the transport drum. 3

are arranged. These guide drums 15a, 15b may be passively rotatably mounted on the machine frame 5.

Alternatively, one or both of these guide drums 15a, 15b can be actively driven by the controller 1 in a controlled manner. By specifying the rotational speed of at least one of the guide drums 15a, 15b in function of

Rotational speed of the transport drum 3, the

Stress of the sheet 13 are influenced during its processing. The fabric 13 is fed to the transport drum 3. As a result, the slippage during transport can be minimized and a high quality of processing by the at least one tool 21 can be ensured.

The distance of the tools 21, 21 'to the transport drum 3 can be changed between a further from the transport drum 3 remote position and a working position for processing the sheet 13. If the guide rail 7, 1 is mounted on the machine frame 5, that their distance to the transport drum 3 can be changed, all can at this

Guide rail 7, 7 'arranged tools 21, 21' are moved simultaneously in the working position or in the rest position.

Alternatively or additionally, tool holders 19, 19 'can be attached to the respective carriages 9, 9', e.g. by means of the

Control 1 controllable drives, in particular by means of spindle drives so arranged to be movable so that they are attached to the tools 21, 21 'to

Transport drum 3 can move away or from the transport drum 3. In the illustration in Figure 2, the tool holder 19 in the solid lines

shown illustrated first pivot position of the pivot arm 10 in the rest position. In the illustrated by dotted lines second pivotal position of the pivot arm 10 ', the tool carrier 19' is shown in the working position.

On such a movable tool holder 19, 19 '

arranged tools 21, 21 'can be independent of

Tools 21, 21 'to other tool holders 19, 19' adjusted or brought into positions with predetermined radial positions with respect to the drive axis Al.

If a tool 21, 21 'such as a pinch roller is resiliently held on such a tool holder 19, 19', in this way, for example, the pressing force can be set, controlled or regulated, with which the pressure roller the fabric 13 against the

Transport drum 3 presses.

FIG. 3 shows a cross section of a part of a

Rollenplotters, wherein at least one tool 21 on a pivotable about the transport drum 3 first

Guide rail 7 and arranged on an associated carriage 9 transversely to the conveying direction of the fabric 13 is displaceable.

The guide rail 7 is in turn pivotable about the transport drum 3 by means of pivoting arms 10 around

Machine frame 5 stored. Parallel to the guide rail 7 and the transport drum 3, a rotatable about a rotational axis A4 brush roller 23 is arranged. The brush roller 25 preferably extends over the entire width of the transport drum 3. The brush roller 23 may e.g. be rotatably mounted on at least two lateral roller supports 25, which are connected to the guide rail 7.

Preferably, the roll supports 25 are motorized

slidably mounted on the guide rail 7. Thereby, the position or the distance of the brush roller 23 relative to the guide rail 7 and relative to the transport drum 3 can be changed. In particular, by specifying a specific working position of the brush roller 23, the controller 1 can determine its effect on a fabric 13 to be processed. Parallel to the guide rail 7 and the transport drum 3, a terminal block 27 is arranged. The clamping strip 27 preferably extends over the entire width of the transport drum 3. Alternatively, the terminal strip 27 may comprise one or more sections which extend over only a respective portion of the width of the transport drum 3. The terminal strip 27 is held by means of at least one strip carrier 29 on the guide rail 7. The rail carrier 29 is mounted on the guide rail 7 in a motor-displaceable or electromagnetically displaceable manner.

Preferably, the strip carrier 29 is resiliently formed.

This allows the position or the distance of the terminal block 27 relative to the guide rail 7 and relative to

Transport drum 3 can be changed. In particular, the controller 1 can pretend at least one position of the terminal block 27, in which the sheet 13 of the terminal block 27 with a certain clamping force against the

Transport drum 3 is pressed, and at least one further layer in which the terminal strip 27 is arranged spaced from the fabric 13 and thus exerts no force on the fabric 13.

The at least one tool 21 is arranged in the conveying direction between the brush roller 23 and the terminal block 27. If a sheet 13 is to be processed orthogonal to the conveying direction with the tool 21, the

Speeds of the pivot arms 10 and the transport drum 3 equal. This includes the special situation in which the transport drum 3 and the

Do not move the swivel arms 10.

Preferably, the sheet 13 during the

Processing with the at least one tool 21

held orthogonal to the conveying direction by the terminal block 27 pressed against the transport drum 3. Additionally or alternatively, the rotating brush roller 23 can ensure that the sheet 13 at the

Transport drum 3 is applied, and that the

Processing point of the fabric 13 is as free as possible of tensile forces.

This is particularly advantageous if at least temporarily weak points in the fabric 13 are created by the processing of the fabric 13 with the tool 21, in particular when the fabric 13 is separated with the tool 21 transversely to the conveying direction.

After processing with the tool 21 is the

Terminal block 27 withdrawn. The fabric 13 or the two separate sections of the fabric 13 can be further promoted by rotating the transport drum 3. Preferably, the advancing portion of the sheet 13 by the opposite direction of rotation to the transport drum 3 further rotating brush roller 23 held on the transport drum 3. Once this section is available without additional support from the

Transport drum 3 is taken, the brush roller 23 can be withdrawn.

At least one of the two pivot arms 10 may comprise a toothed drive wheel or pinion 31, which meshes with an adjacent sprocket 33 on the respective side of the machine frame 5. Preferably, both pivot arms 10 each comprise a pinion gear 31. The toothing of

Sprockets 33 is preferably formed on the inside.

The sprockets 33 preferably extend only over a portion of a full circle, as shown in FIG. This allows a more compact structure of the role plotter. Preferably, at each of

Swivel arms 10 each arranged a motor for driving the associated pinion 31. These motors are operated synchronously. Due to the two-sided drive can

torsion-free movement of the guide rail. 7

be ensured.

At a further guide rail 7 "at least one further tool 21" is arranged. This can, as shown in Figure 3, be arranged on a further carriage 9 ", which also transverse to the conveying direction of

Sheet 13 is displaced. Alternatively, the Further tools 21 "may also be arranged on a tool carrier 19", which is connected directly to the guide rail 7 "or the machine frame 5. Preferably, this tool carrier 19" can be mounted on the

Drive drum 3 is moved radially in the direction of the axis A3 "between a rest position and a working position and / or rotated about the axis A3". The further guide rail 7 "is arranged stationarily on the machine frame 5. Alternatively, the second guide rail 7" could be movably connected to the machine frame 5 analogously to the first guide rail 7. Preferably, a guide drum 15b, 15c is arranged upstream of and downstream of the tool 21 ", these guide drums 15b, 15c being drivable, for example

Pressure rollers that press the fabric 13 against the transport drum 3 before and after the processing point. The guide drums 15b, 15c may be relative to

Transport drum 3 controlled by the controller 1 to be motorized displaced. Thereby, the distance between the guide drums 15b, 15c and the

Transport drum 3 is changed and adjusted, for example, according to the thickness of the sheet 13 to be processed. In addition, the pressing force with which the fabric 13 is pressed by the guide drums 15b, 15c against the transport drum 3 can thus be changed. As a result, the arrangement and guidance of the fabric 13 at the processing site can be improved. at Demand, the sheet 13 at the

Processing location e.g. by specifying appropriate positive or negative values for the speeds of the

Guide drums 15a, 15b defined depending on the speed of the transport drum 3 are tightened. This is particularly advantageous in multilayer and / or

elastically deformable sheets 13 such as e.g.

Quilts or foams. When cutting the

Sheet 13 transverse to the conveying direction prevent the guide drums 15b, 15c from sliding away portions of the sheet 13. Separated sections are securely held in contact with the transport drum 3.

FIG. 4 shows, by way of example, a fabric 13 that can be used with a roll plotter during transport in

Conveying direction is processed by a plurality of tools 21, 21 ", in which case the following work steps are carried out: a) Creation of three parallel wave-shaped

Welding seams 37

b) cutting along two longitudinal edges in the conveying direction 39

c) cutting along transverse edges 41

This can be done with different configurations of the

Rolleplotters be effected. In a preferred

Configuration are on the pivoting guide rail 7 three carriages 9, each with an ultrasonic sonotrode and at least one other carriage 9 is arranged with a cross cutter as tools 21. At the fixed further guide rail 7 "two slitters are arranged as additional tools 21" to the required for the preparation of the longitudinal sections positions.

The processing of the sheet 13 may e.g. The following process steps include:

The transport drum 3 conveys the fabric 13 at a constant rotational speed in the conveying direction indicated by the arrow PI. The laterally arranged slitters continuously cut the

Long edges 39. Optional could be at each of these

Slitter in addition a Rollsonotrode be arranged as another tool 21 "

Cutting edge immediately after cutting.

The guide rail 7 is pivoted at the same speed as that of the transport drum 3. The cross cutter cuts the fabric 13 along the front transverse edge 41. Optionally, an ultrasonic sonotrode for sealing the cut edge could also be arranged in the cross cutter. Thereafter, the carriage 9 with the ultrasonic sonotrodes transversely to the conveying direction and optionally the pivotable guide rail 7 in

Direction of conveying positioned so that the ultrasonic sonotrodes are arranged at the initial positions of the wave-shaped welds 37. Coordinated with the proportion of the relative speed of the fabric 13 and the ultrasonic sonotrodes in the conveying direction, the carriage 9 according to the predetermined contours of

Weld seams 37 moved back and forth transversely to the conveying direction. In synchronism with this, the relative speed of the fabric 13 and the ultrasonic sonotrodes is determined by alternately pivoting the guide rail 7 in and against the conveying direction corresponding to the local

Alignment of the welds 37 reduced and

increased. In places where the welds 37 in the

Are aligned substantially transversely to the conveying direction, the speed of rotation of the guide rail 7 in

The largest and thus the share of

Relative speed of ultrasonic sonotrode and

Sheet 13 in the conveying direction smallest. This ensures that the carriage 9 when out and

Do not exceed preset maximum speeds.
