Definitions

• the present invention relates to a method for the production of blanks from cardboard or cardboard-like materials with the features of the main claim and to an apparatus for carrying out the method according to the preamble of claim 4.
• longitudinal direction of the workpiece or carton blank that direction is meant which is defined by the direction of movement of the transfer drive, with the aid of which the workpieces, starting from the catchment area in the machine, are conveyed through the individual processing stages. If the longitudinal directions of all processing modules to be traversed one after another are on a single continuous straight line, this is referred to as a so-called inline machine (see catalog Klett, for example).
• the processing modules include all the individual assemblies required in the production of such carton blanks, within which the blanks are each subjected to a special type of processing.
• a device suitable for this purpose results from the features of claim 4.
• the invention is based on the basic concept of designing the plotter module or the plotter module such that the respective machining tool can only be moved transversely on the plotter module, while the necessary longitudinal direction of the machining is not effected by the plotter module itself but by a correspondingly redesigned transfer device for transporting the plotter module Carton blank is realized by the processing machine through.
• the transfer device is designed for this purpose so that, preferably via a control electronics, both forward and backward in the longitudinal direction is movable, if possible with variable speed.
• the carton blank taken along by the transfer drive is therefore moved under the processing head of the plotting device solely by the transfer drive of the processing machine, while the processing head of the plotter device is movable exclusively transversely to the longitudinal direction.
• the advantage of the invention lies in particular in the savings of an additional longitudinal drive in the plotter module, because the carton blank is guided in any case by the transfer drive of the machine in the longitudinal direction through the plotter.
• the plotting device only allows a drive movement of the processing head in the transverse direction, while the longitudinal direction, in which the workpiece must move, is realized by the transfer drive of the machine tool.
• the plotting device can even create longitudinal machining lines in the case of a machining head which is stationary in the transverse direction, or machining lines running in the transverse direction in the longitudinal direction of the stationary transfer drive.
• the plotter device according to the invention is also able to carry out the numerous processing lines produced by flat bed punching or rotary punching.
• Preferred is a development in which the transfer drive of the workpieces, starting behind the feeder station and preferably up to a downstream stacking device is located exclusively on a single straight line.
• the processing tool of the plotting device is rotatable into any desired rotational position resulting from the vector addition of the velocities in the longitudinal and transverse directions at each point in time of the machining.
• the machining tool is always exactly parallel to the processing line that has to be produced, so that in accordance with fine digital processing of the control data and optically circular contours can be cut or the like.
• the invention has recognized to the extent that it depends solely on the Relativbewe- movement between the machining head and workpiece for the processing of such workpieces and thus saves on the plotter a separate longitudinal drive, which, however, is replaced by the correspondingly redesigned transfer drive.
• At least the speeds of the upstream processing modules can be reduced in such a way that sufficient time is available for processing in the plotter module.
• the reduction of the speeds can go to a standstill.
• processing head on the plotter module has a vertical axis of rotation about which it can be stored by means of a separate drive in any desired rotational position.
• the respectively required rotational position results from the vectorial addition of the speeds in the longitudinal direction and transverse direction.
• the machining tool is always exactly parallel to the respective oblique direction, in which the processing line points at the point of processing.
• Fig.l a first embodiment of the machine; 2 detail view of a suitable transfer drive; Unless otherwise stated below, the following description applies to all figures.
• Starting material for the present process are workpieces 2 of originally arbitrary starting form.
• the processing lines are cuts, slits, cracks, grooves, perforations or even fold lines.
• 1 processing lines 5 can occur in such blanks, which extend neither exclusively in the longitudinal nor in the transverse direction.
• the longitudinal direction is defined by the so-called transfer drive direction 6, in which direction the workpieces 2 are guided through the individual processing stages 7a, 7b, 7c.
• inline machine in which all transfer drive directions of the individual processing stages 7a-c lie on a single straight line. It is essential that those processing lines 5, which run neither exclusively longitudinally nor exclusively in the transverse direction, are produced by a plotting device 8, which has a working head 9 movable in parallel above and relative to the plane of the workpiece to be machined Distance to the workpiece only in the transverse direction to each point of the respective processing line is movable, is activated for processing at each point of the workpiece and then driven in the activated state along the respective inclined processing line 5 with controlled feed only in the transverse direction 10, while the workpiece simultaneously is positioned in the longitudinal direction by means of the transfer drive 11 of the machine processing relative to the working head 9 of the plotter 8.
• the machining head 9 which also serves as a tool carrier, can only be moved transversely to the workpiece via a suitable electromotive drive device, while the workpiece is positioned for processing by the combined activation of the above-mentioned motor drive device and the drive device for the transfer drive 11 becomes.
• the longitudinal direction 12 of the plotter movement is therefore realized by appropriate control of the transfer drive 11.
• the machining head with its tool carrier has a rotary head 13, so that the machining tool or the tool carrier of the plotting device 8 is rotatable during the machining of the respective workpiece 2 into any rotational position resulting from the vectorial addition of the speeds in the longitudinal direction 12 and transverse direction 10 results.
• the rotary head 13 has a rotary drive 14 suitable for this purpose, which, just like the transfer drive 11 and the drive for the transverse direction 10, is acted upon by control signals by an electrical control 15 in order to attach the desired obliquely extending processing line to the processing machine.
• the electric control 15 for the plotter device has as input the geometric data of the finished section 1, so that the respective positioning of the workpiece 2 can take place via corresponding position sensors while at the same time the necessary movements in oblique direction of the respective processing lines by simultaneous control of the motors Longitudinal and transverse drive.
• processing modules 17a, b, c are arranged directly one after the other.
• the plotting device depending on the time required for processing, can cause a backwater in that area of the machine, which is passed in front of her from the workpieces, a further electronic control 16 is provided, with the help of at least the speeds of the upstream processing modules here only 17a can be slowed down so that the plotter module 19 receives the time necessary for the respective machining of the workpiece 2.
• the reduction of the transfer speeds in front of the plotter module 19 relates in particular to all drive units which are arranged between the feed station 18 and the input to the plotter module.
• Fig.l shows in the lower part different stages of production of an originally rectangular piece of work 2, in which initially round holes are introduced (first processing step), further oblique cuts or perforation (further processing step) and then a corresponding outer contour, like him the carton blank must have (third processing step).
• Fig.l shows a development in which the machining tool 20 is rotatable on the plotting device 8 about a vertical axis in any rotational position.
• a rotary drive 14 acting on the rotary head 13 which is controllable in such a way via the electric control 15 for the plotter module during the machining of the respective workpiece that the respective rotational position from the vectorial addition of velocities in the longitudinal and transverse directions.
• Fig.l shows a further development in which the machining tool 20 of the plotter module 19 is seated on a transverse bridge 25 rigidly connected to the machine frame and can only be moved in this direction in the transverse direction 10.
• this bridge is rigidly connected to the machine frame on both sides.
• transport rollers 21a, b and 22a, b are provided.
