Definitions
- the present invention relates to a cutting machine for cutting stacked sheet material, for example paper, cardboard or the like.
- the cutting machine according to the invention is in particular a plane cutter, in particular a high-speed cutter.
- DE 31 01 911 C2 discloses a device for cutting paper, cardboard or the like and a method for operating the device.
- the cutting machine disclosed in DE 31 01 911 C2 is used for cutting stacked sheet material.
- the cutting machine has a table for receiving the material to be cut and a feed saddle for displacing the material to be cut in the direction of a cutting plane of a cutting blade of the cutting machine.
- the advancing of the item to be cut by means of the advancing saddle serves to ensure that the stack is cut by the cutting blade at the intended dividing lines. Even small displacements, for example dimensional deviations due to paper distortion, can result in the knife no longer making the cut on the desired dividing line, but rather being offset from it.
- the sheets are printed in such a way that the individual patterns do not lie directly next to one another, but between them distances remain. It is then necessary between the main cutting processes, i.e. those cutting processes in which a stack of blanks is separated from the rest of the material to be cut and insofar as no cut waste is produced, to provide interim cuts, with cut waste being produced in these intermediate cuts.
- edge cuts are also typically provided to trim the edge surfaces thereof prior to cutting the actual stack. The advantage of edge cuts can be seen in the fact that after the edge cuts have been made, the stack to be cut is in a defined shape or dimension, which has a decisive influence on the accuracy of the subsequent main cutting processes.
- the cutting machine disclosed in DE 31 01 911 C2 provides a two-part table, with a front table of the table holding the cut material, also as a Called benefit stack, picks up and a rear table of the table picks up the good to be cut.
- the front table and the rear table can be slid relative to one another to form a gap between them, with the front table and the rear table being displaced relative to one another during an intermediate cut, so that the gap is formed and, accordingly, when the cut is made, the cutting waste produced during the intermediate cut is direct pass through the gap formed between the front table and the rear table into a collection device for cutting waste without manual intervention.
- a disadvantage of a cutting machine of the aforementioned type is that the cutting waste produced during the cut is always fed to one and the same collection device, so that it is not possible to separate cutting waste of different quality, size or quality. This is particularly relevant when there is a need to collect different types of trimmings separately, for example separating trimmings that have printed areas from trimmings that are unprinted. This is particularly relevant to the extent that the disposal and/or recycling of trimmings that is printed involves higher costs or greater effort than is the case with trimmings that have no printed areas. It is an object of the present invention to provide a cutting machine which overcomes the aforementioned disadvantages.
- the cutting machine serves to cut stacked, sheet-like material, in particular stacked sheets of paper, cardboard or the like.
- the cutting machine has a table, the table having a front table and a rear table, the front table serving to receive the cut material and the rear table serving to receive the material to be cut.
- the front table typically faces the user of the cutting machine.
- the front table and the rear table are mutually slidable bar to form a gap between them.
- the cutting machine has a device that can be operated in at least two different operating modes, wherein in a first operating mode of the device, trimmings that have passed through the gap are fed to a first collection device by means of the device, and in a second operating mode of the device, trimmings that have passed through the gap are fed by a second collection device Collection device is supplied. Depending on the operating mode, the cutting waste produced during the cut is fed to the first collecting device or fed to the second collecting device. This makes it possible to separate printed cutting waste and unprinted cutting waste. For example, the first collecting device is used to collect unprinted cutting waste or cutting waste with only a small proportion of printed areas and the second collection device is used to collect printed offcuts.
- the cutting machine thus makes it possible in a simple manner to separate printed off-cuts from unprinted off-cuts or off-cuts with only a small proportion of printed areas, since typically either printed off-cuts or unprinted off-cuts are produced during a cut, since the patterns are usually are repeated on the sheet of blattför-shaped Goods, for example, in columns and rows of individual patterns are separated.
- the cutting machine is preferably operated in such a way that following a main cut, in which a stack of blanks is formed, several intermediate cuts are provided, in which cutting waste is produced, with the first intermediate cut producing printed cutting waste, which is collected in the second collection device , and during the subsequent second intermediate cut, unprinted cutting waste is produced, which is collected in the first collection device.
- the device preferably has a deflector device that can be adjusted between a first position and a second position, the adjustable deflector device being in the first position in the first operating mode of the device and deflecting the trimmings in a first direction, and the adjustable deflector device being in the second mode of operation of the device is in the second position and diverts the trimmings in a second direction, which is not identical to the first direction.
- the deflection device can be, for example, a baffle plate or the like.
- the device consists exclusively of the adjustable discharge device.
- the diverting device is located below the formable gap in the area of the separating surface from the front table to the rear table is arranged and passing through the gap cutting waste gravitationally derives with support.
- the discharge device is made in particular for the discharge device to form an inclined plane in the manner of a chute for the cutting waste.
- the cut waste that passes through the gap is fed directly to the respective collection device by means of the discharge device.
- the cutting machine has a control device for controlling the device in order to change the operating mode.
- the cutting machine has means for adjusting the discharge device and the preferably electronic control device is set up to control the means for adjusting the discharge device.
- the user of the device knows whether cutting waste with printed areas is produced during the cut to be carried out or not. The user can then switch the device to the appropriate operating mode by operating the control device.
- the cutting machine includes a classification device which is designed to classify the trimmings produced during the cut before the cut is carried out on the basis of the proportion of printed surfaces in the total area of the trimmings and/or to classify them accordingly classify whether the trimmings are free of printed areas.
- the classification of the trimmings occurring during the cut thus takes place before the actual cut, so that the trimmings are not classified as such, but before the trimmings are even produced, the trimmings arising during the cut are classified by the classification device.
- This is technically not particularly complex and is simpler than an assessment or classification of the trimming waste that has already accumulated, since the trimming waste that has accrued is generally present in a disorderly manner, and in particular a possibly printed area is not necessarily visible.
- the cutting machine has a sensor device for the optical inspection of an upper side of the item to be cut, with an evaluation device being set up to detect printed areas based on the output data of the sensor device.
- the output data output by the evaluation device preferably serve as input data for the classification device.
- the evaluation device can definitely be part of the sensor device or the classification device. Since the cutting edge or cutting plane of the cutting knife is well known, the sensor device and the evaluation device can be used to determine very precisely whether the cutting waste produced during the corresponding cut has printed areas or not. As a result, it is not necessary to have prior knowledge of the type of cutting waste that occurs during the corresponding cut, since the cutting machine is set up by means of the sensor device and the evaluation device to classify the cutting waste that occurs.
- the cutting machine to have a memory unit instead or in addition, the memory unit comprising data, these data relating to cuts to be made on the item to be cut and the cutting waste produced during the respective cut being stored in the memory unit whether the trimmings are free of printed areas and/or the proportion of printed areas in the total area of the trimmings is stored, the classification device being designed to access the data stored in the storage unit.
- the data stored in the storage unit are thus the basis for determining which collection device is supplied with the cutting waste produced during the corresponding cut.
- the control device is set up in particular to control the device in particular the means of the diverting device to control depending on the classification of the trimmings.
- the cutting machine has display means for displaying the operating mode of the device and/or the classification of the cutting waste produced during the cut. This makes it possible for an operator of the cutting machine to check whether the correct operating mode has been selected and/or whether the classification of the waste produced during the cut is correct and/or to select the operating mode in accordance with the classification.
- control device is set up to prioritize a setting made by the operator over a setting made automatically by the classification and/or the control device.
- the adjustability of the discharge device can follow in different ways.
- the discharge device can be displaced and/or parts of the discharge device can be displaced in relation to one another.
- the diverting device has two mutually displaceable sections in a similar manner to the front table and the rear table, with a gap being formed between the two sections in the first operating mode and the cutting waste occurring during the cut passing through this gap enters the first collection device, and in the second operating mode the gap between these two sections is closed and in this way the cutting waste produced during the cut reaches the second collection device.
- the diverting device can be moved together with the front table, so that it is not necessary to provide a separate mechanism or means for moving the diverting device, but rather to adjust the position of the diverting device by moving the front table change. According to the mode of operation, the front table is more or shifted less far to the back table.
- a front part of the deflection device is connected to the front table and can be displaced together with it. Accordingly, in the first operating mode, provision is made for the front table and the rear table 4 to be pushed further apart than is the case in the second operating mode, or vice versa.
- the adjustability of the diverting device is formed by a pivoting ability of the diverting device and/or parts of the diverting device.
- the device is combined with an adjustability of the first collecting device and/or the second collecting device or includes such adjustability, in particular such that in the first operating mode the first collecting device is arranged below the gap between the front table and the rear table and in the second mode of operation, the second collection means is located below the gap between the front table and the rear table.
- the cutting machine preferably has a feed saddle for displacing the material to be cut in the direction of a cutting plane of a cutting blade of the cutting machine.
- the back table is fixed and the front table is slidable to form the gap.
- the adjustable diverting device extends over the entire width of the table, the width of the table running perpendicular to the feed direction of a feed saddle of the cutting machine and parallel to the cutting plane of the cutting machine. It is considered to be particularly advantageous if the device has a conveyor belt, in particular an arrangement of several conveyor belts, for feeding the cut waste that has passed through the gap to the respective collecting device.
- the conveyor belt or one of the conveyor belts is arranged below the gap that can be formed in the area of the separating surface from the front table to the rear table and the cutting waste passes through the gap onto the conveyor belt.
- the conveyor belt conveys the cuttings coming through the gap in a first direction and in the second operating mode conveys the cuttings coming through the gap in the opposite direction, i.e. the conveying direction when changing the operating mode is reversed.
- the discharge device can be arranged in the region of the conveyor belt in order to discharge the cutting waste conveyed on the conveyor belt.
- the conveyor belt can always be operated in one and the same direction, with the cutting waste transported on the conveyor belt being fed to the respective collection device by means of the diverting device, for example the diverting device being designed as a pivotable wedge or pivotable guide plate.
- the diverting device has a stripping device that rests against the conveyor belt, in order to achieve reliable diverting of the trimmings by means of the diverting device.
- a scraping device can be designed, for example, as a felt or brush or elastic lip.
- the diverting device is connected to the conveyor belt in the conveying direction of the conveyor belt.
- the diversion device can be designed in a similar way to that of a device designed directly below the gap between the front table and the rear table discharge device is the case.
- the device has an adjustable covering device, the covering device covering the second collecting device in the first operating mode and covering the first collecting device in the second operating mode. It is quite conceivable that the diverting device or a part of the diverting device forms the covering device. This prevents cutting waste from getting into the first collection device or the second collection device by mistake.
- the first and the second collection device are components of a common waste collection device, for example the collection devices are formed by different compartments of the waste collection device.
- the method comprises the following method steps:
- step a
- step b
- step c
- step c. performed cut is an edge cut or an intermediate cut.
- process step a. and/or process step b. computer-assisted, in particular using a cutting program stored in the memory device.

- a first edge cut is made, with the cutting blade 7 of the cutting machine 1 penetrating the material 2 to be cut in the unprinted area 23 between the first printed area 22.1 and the edge.
- This first edge cut is identified by the dotted line 32.1.
- the material 2 to be cut is then shifted by means of the feed saddle 5 in the direction of the cutting plane 6 and then a second edge cut is carried out, in which the cutting blade 7 penetrates the material 2 to be cut in the first printed area 22.1.
- This second edge cut is identified by the dotted line 32.2.
- the second edge cut produces cutting waste 11 which has printed areas.
- the first edge cut produces cutting waste 10 that is free of printed areas.
- the trimmings 10 having no printed portions are collected separately from the trimmings 11 having printed portions.
