Description

The invention relates to a punching machine with a magnetic cylinder and a counter-punching cylinder and a method for producing such a punching machine from a printing press, in particular single-color printing machine, wherein the printing machine includes a frame with at least one printing part with at least one pressure roller and at least one counter-pressure roller.

Both printing presses and punching machines are basically known in the art. Such printing machines comprise a printing part with printing cylinder or pressure roller and counter-pressure roller. From the WO 2005/021265 A2 For example, a sheet-fed offset printing machine for printing individual sheets is known. This sheetfed offset printing press comprises, in addition to a printing or coating unit, a device for punching out cutouts in the sheets in the printing or coating unit of the printing press. The printing or coating unit comprises a rubber or varnish cloth cylinder and a counter-pressure cylinder, which limit a gap for the passage of the sheets. One of the cylinders is provided with a stamped sheet having over its outer surface protruding burrs. The printing or coating unit further comprises a suction device for sucking the punched out on passing through the gap from the cut-outs punching waste. In order to prevent lifting of the sheets from the other cylinder as a result of suction applied to the sheet negative pressure, the punching sheet is provided in the circumferential direction of the rubber or varnish cylinder with protruding Andruckleisten pressing the sheet in the region of the gap against an outer surface of the other cylinder ,

All printing and punching machines are expensive to buy. Furthermore, at least the printing presses must be retracted to achieve a consistent precision in the processing.

The present invention is based on the object to provide a cost-effective punching machine that allows a particularly precise punching already directly after the commissioning of the punching machine. Furthermore, the invention has for its object to provide a method for producing such a punching machine.

The object is achieved for a punching machine according to the preamble of claim 1, characterized in that an at least five years frame and a precision bearing are provided for the magnetic cylinder. For a method according to the preamble of claim 25, the object is achieved in that a printing machine with a frame with at least one printing part with at least one pressure roller and at least one counter-pressure roller is converted, wherein in the frame, the pressure roller through at least one magnetic cylinder and the counter-pressure roller at least one counter punch cylinder to be replaced and at least one precision bearing is provided for the magnetic cylinder. Further developments of the invention are defined in the dependent claims.

This creates a cost-effective way to provide a punching machine based on a printing press available, so that only individual parts of the printing press need to be replaced, but not the cost of recreating a punching machine must be spent. The further great advantage is that, by using a frame of the printing press which is aged under essentially constant operating conditions, this tension arm is thus able to achieve particularly good concentricity properties for the cylinders mounted in it. Instead of the printing cylinder or the pressure roller of the magnetic cylinder is now provided in conjunction with the counter-punching cylinder to make any type of punched paper and cardboard can. Since usually a normal storage of the pressure roller with a lower requirement for the precision of the storage is sufficient for a printing process, a precision bearing for the magnetic cylinder and the punching cylinder proves to be extremely advantageous because in punching a high precision is required, so that the punching result Such a precision storage can be optimized. Advantageously, a hydraulic bearing of the magnetic cylinder is selected as a precision bearing, as a result, a particularly precise storage can be achieved even when processing cardboard. Especially with the punching of cardboard boxes, spring loading can cause the cylinder to lift or jump when the magnetic cylinder is stored, so that the precision of the position of the magnetic cylinder can not or at least can hardly be ensured.

In order to ensure a precise execution of punching operations, the magnetic cylinder advantageously has a concentricity of ± 5 microns to its bearings. It also proves to be advantageous to provide the counter-punching cylinder with a concentricity of ± 5 microns to its bearings. As a result, a particularly precise punching design is possible.

Magnetic cylinder and counter-punching cylinders are advantageously designed so that can be performed with these punched, punched, perforated, grooving or creasing and window punching. Depending on what type of punching is to be made, Are a protector or punching sheet formed on the counter punch cylinder and at least one punched profile or punching element on the magnetic cylinder accordingly.

It proves to be further advantageous to provide at least one adjusting device for adjusting or adjusting the position of the magnetic cylinder. Hereby, the positioning of the magnetic cylinder is also possible with a high precision. In particular, counter-punching cylinders and magnetic cylinders can thereby be aligned precisely with one another in order to achieve an optimum punching result.

The counter-punching cylinder is or is advantageously provided with the protector sheet, which is advantageously designed as a hardened sheet. To accommodate the protector sheet of the counter-punching cylinder is advantageously provided with a clamping device or a tensioning rail system for releasably securing the protector sheet. It is also possible to provide another fastening system for securing the protector sheet. For receiving the clamping device, the counter-punching cylinder may advantageously be provided with at least one recess and / or recess. This can be arranged in particular in the region of the counter-punching cylinder, which lies remote from the processing region, ie the region which comes into contact with the paper sheets or cardboard to be punched. Likewise, the protector sheet is advantageously provided with at least one fastening device for fastening to the counter-punching cylinder, in particular with openings, recesses or cut-outs for the engagement of fastening means, such as screws or bolts. This is a particularly stable and at the same time precise arrangement of the protector plate on the counter punch cylinder possible. Alternatively, the protector sheet could be glued to the surface of the counter-punching cylinder, but then usually no longer the required hardness can be guaranteed, since the adhesive layer is compliant which, so that it can lead to inaccuracies during the punching process. Further, replacement of the protector sheet is less easily possible than providing releasable fasteners such as screws or bolts. An exchange of a worn protector sheet is thus much worse possible with the provision of an adhesive layer than when releasable fastening devices are provided. The provision of an adhesive layer also has the disadvantage that it would have to be removed by solvents, which in turn, however, attack the adhesion of the magnets of the magnetic cylinder and thus could damage or at least partially render it useless.

By completely removing the printing part, the dimensions of the punching machine in height compared to the printing press can be reduced, which increases the ease of use and thus reduces set-up times.

It is also possible to convert the counter-pressure roller itself to the counter-punch cylinder, so do not remove it and replace it with a new counter-punching cylinder. The counter-punching cylinder can be surface-treated in each case, in particular chromed and ground according to the requirements and provided with the protector sheet.

Furthermore, safety devices for protecting users are also advantageously provided in particular in the region of the magnetic cylinder and / or the counter-punching cylinder. In particular, at least one light grid may be provided as a safety device against unintentional engagement in a boom chain for a single sheet removal. In addition to these safety devices further operating means may further be provided, such as means for manually or automatically advancing the magnetic cylinder and / or the counter-punching cylinder or a jogging control means for stepwise forward and / or backward movement of the magnetic cylinder for providing this with a punched profile or Punching element or for dressing of this. Not only in the first commissioning, but also below, it proves to be advantageous to position the magnetic cylinder easily accessible for a change of stamped sheet metal or punching elements and for later trimming the cylinder to consistently provide the same concentricity as possible to ensure a precise punching image can. In particular, a calibrated dressing device can be provided for trimming the magnetic cylinder in the μm range.

Furthermore, it is possible to provide sensors in the punching machine, which regularly monitor the state of the magnetic cylinder and possibly also of the counter-punching cylinder in terms of their concentricity and other state. Furthermore, a measuring device and a display device for measuring, setting and displaying the position of the magnetic cylinder and / or the counter-punch cylinder can be installed or provided to each other. Advantageously, the measuring or interrogation device is digitally designed for determining the position of the magnetic cylinder and / or the counter-punching cylinder. Also, a digital display device for indicating the cylinder position and / or the cylinder provision between the magnetic and counter-punching cylinders can be provided.

Advantageously, the magnetic cylinder is provided with a number of pockets for engagement of grippers for fixing holding sheets.

The object is also achieved by the use of a cast steel frame of an at least five-year-old offset printing machine for producing a punching machine. Especially when using a steel cast frame of an at least five-year-old offset printing press ensures that this is aged with low voltage at constant operating conditions, so that there are particularly good long-term constant concentricity properties for the punching machine. As a result, the desired precision can be achieved particularly well in punching operations.

The object is also achieved by a punching machine in which at least one numbering device and / or an impression device is provided for numbering. By such a numbering device or imprinting a numbering of sheets or individual parts can be done on a sheet. By combining with a punching machine, it is thus possible in particular to delimit areas on a sheet of material by perforations and / or punched holes and to provide them with separate numbering, which in particular are continuous. As a result, for example, not only labels, but also stamps, etc. or security prints can be produced with a consecutive numbering on sheets.

Advantageously, at least one numbering shaft and switching curves can be provided and / or a book printing unit. It is also possible to provide at least a sheath cylinder and a nylon plate, in each of which it is possible to apply numbers to the sheets processed in the machine.

In order to transfer color from one rubber roller to the next, a transfer roller is advantageously provided. This is integrated into the punching machine instead of a plate cylinder. Also, at least one distributor roller may be provided for rubbing paint. It proves to be particularly advantageous to provide an oscillating device for laterally oscillating the distributor roller for triturating the ink. As a result, the color is particularly well evened.

As it proves to be advantageous to provide at least one ink fountain and a squeegee roller in the field of punching machine, so that these helpful for numbering facilities can be arranged to save space in the punching machine.

A numbering shaft can be inserted instead of a rubber cylinder otherwise provided in a printing press in this for forming the punching and numbering machine. A plate cylinder present on a regular printing machine can either be removed or bypassed. Due to the relatively large diameter whose fundamental wave is very stable, so that it can be used very well for the individual elements of the punching and numbering machine. When bridging the plate cylinder, its bearing can be designed as a flange bearing and a roller bearing can be arranged on the flange bearing, so that only one piece needs to be screwed in and thus the printing press can be converted in a simple manner. When converting the printing press into a punching and numbering machine, the numbering station can be designed either as a first station or as a second station and, correspondingly, as a second station or as a first station. The order can be made dependent on the respective punched and numbered sheet or the finally resulting stamped objects.

For a more detailed explanation of the invention, an embodiment of this will be described in more detail below with reference to the drawings. These show in:

1 a schematic diagram of a printing machine with a pressure roller and a counter-pressure roller and indicated magnetic cylinder and counter-punching cylinder for conversion into a punching machine,

2 a side view of a magnetic cylinder for installation in the printing machine according to 1 instead of the pressure roller there,

3 a side view of a counter-punching cylinder according to the invention without protector sheet,

4 a sectional view of the counter-punching cylinder according to 3 along the line AA, without protective sheet,

5 a sectional view of the counter-punching cylinder according to 3 along the line AA with attached protector sheet,

6 a detailed view of the 5 in the area of a clamping rail receptacle for clamping the protector sheet,

7 a plan view of the protector plate and its fastening device with additionally enlarged details of the fastening device and the clamping rail, and

8th a schematic diagram of a punching and numbering machine, manufactured on the basis of a printing press.

1 shows a schematic diagram of a printing press 1 with a pressure roller 2 and a counter pressure roller 3 , The printing press 1 also has a housing 4 and at least one frame 9 on, are arranged in the pressure roller and counter-pressure roller and other components of the printing press.

As by the arrows 5 . 6 indicated, are used to retool the printing press 1 in a punching machine 1' the pressure roller 2 and the counter-pressure roller 3 taken and instead a magnetic cylinder 20 as well as a counter punch cylinder 30 in the case 4 inserted into the machine. This is through the arrows 7 . 8th indicated. The resulting punching machine is denoted by the reference numeral 1' indicated.

It thus becomes the frame 9 the used printing press continues to be used for the new punching machine, which has the advantage that due to the use of the printing press at substantially constant operating conditions, the frame has a low stress, so that a precise storage of the magnetic cylinder in particular, but also the counter-punching cylinder is possible. For example, the press may have run 40 to 50 million presses before being converted to the punch press. It is thus a very precise storage and guarantee constant concentricity properties for magnetic cylinder and counter punch cylinder possible.

Instead of replacing the counter pressure roller against the counter punch cylinder 30 can the counterpressure roller 3 also removed and converted into the counter punch cylinder. This can in particular be worked up, chrome-plated and ground in order to achieve the desired concentricity required for punching machine utilization. Here, the counter-punching cylinder is also provided with a clamping or clamping rail system for receiving a punching plate, which further down to the 3 to 7 is explained in more detail.

In order to provide a particularly precise storage for the magnetic cylinder, but also for the counter-punching cylinder, the bearings of pressure roller and counter-pressure roller are renewed or by a precision bearing 26 replaced as they are in 2 is indicated. In particular, a hydraulic bearing is suitable here.

Furthermore, side cheeks of the housing 4 the printing press 1 removed and replaced with smaller side panels, since when removing the printing part an upper part of the printing press can be removed. All other cylinders of the printing machine, in particular a plate cylinder, which are arranged above the counter-pressure roller can be removed. This results in a lower height of the punching machine compared to the printing press, thus a smaller footprint, and a lower power consumption, thus lower energy costs. Various safety devices to protect the user and the punching machine can also be installed, these being in 1 not shown. Furthermore, electrical safety circuits are adapted to the new use as a punching machine and a possibly existing safety control is extended or renewed. For trimming the magnetic cylinder and possibly also the counter-punching cylinder, a jogging control can be provided, which allows a stepwise forward and backward movement of the magnetic cylinder and possibly also of the counter-punching cylinder. As a result, adjustments for the desired concentricity of particular ± 5 microns of magnetic cylinder and counter-punch cylinder can be guaranteed at any time.

In order to adjust the magnetic cylinder and the counter-punching cylinder with respect to their position exactly, an electronic digital display, if necessary, on both sides of the punching machine, is provided. Such is in 1 but not shown. Furthermore, sensors for sensing the respective position of magnetic cylinder and counter punch cylinder can be integrated into the machine. These too are in 1 but not shown.

2 shows a partially broken side view of the magnetic cylinder 20 in an exemplary embodiment. The magnetic cylinder 20 has a number of pocket-like recesses 21 on, in the gripper can engage for fixing sheets to be punched. In the area of the gripper edge are additional magnets 22 provided to keep the die safe.

The magnetic cylinder 20 is ground with high precision and has a runout accuracy of +/- 5 μm. This, in combination with the high-precision storage, makes an optimal punching possible. In the bow area 25 of the magnetic cylinder 20 can be recorded in different shapes or individual punch segments to produce the desired stamping images depending on the application. In this case, in particular complete punching, stamping, as for example for labels, perforations, stamped cuts or creases or grooving in any version are possible. The respective shape of the punched pictures as well as the type of punching can be varied as desired.

The 3 to 7 show an exemplary embodiment of the counter-punching cylinder 30 , This one is with a protector sheet 31 provided, which is connected in a special way with this. The connection is made via a clamping rail 32 as they are in 5 is particularly good to see, as well as in the enlarged view in 7 , The clamping rail 32 is in a recess 33 attached to the counter-punching cylinder via a number of screws. Except the recess 33 the counter punch cylinder still has an inner channel 34 in the longitudinal direction, so it is not designed as a solid solid body. This channel 34 is particularly good at the sectional views along the line AA 3 in 4 and 5 refer to. The clamping rail 32 is enlarged in 7 shown. The assembly of both is in 5 to see. The clamping rail 32 has a number of through holes 35 on to these on the body of the counter punch cylinder 30 to be releasably fastened by means of screws. Furthermore, the protector sheet with or without locking screws on the counter-punching cylinder 30 be attached, so only between clamping rail 32 and counter punch cylinder clamped or additionally held there by screws. Without securing screws, replacement of the protector plate is easier and faster.

As 7 can be further removed, has the protector sheet 31 in its edge area 36 recesses 37 on. With the recesses 37 grips the protector plate over the screws for attaching gripper pads 44 time. The protector sheet may further on the lateral surface of the counter-punching cylinder 30 be aligned with the plan.

In his the edge area 36 opposite edge area 38 the protector sheet is replaced by another releasable fastening device 39 held clamped. This includes a screw 40 as well as a nut part 41 , The nut part 41 is with a towards the inner channel 34 the counter punch cylinder extending blind hole 42 Mistake. The blind holes 42 serve for tensioning the protector sheet. In the outer ring or Schmitzring 45 of the counter-punch cylinder 30 are right and left or at both ends tapped holes 46 provided for receiving pivot pins, not shown, in the blind holes 42 intervention.

In particular 4 can be removed, is the counter punch cylinder 30 not always provided with a uniformly shaped lateral surface, but has a remote area 43 on. In 5 is the counter punch cylinder 30 with attached protector sheet 31 shown. The counter-punching cylinder is thus milled and trimmed accordingly for a particularly secure recording of the protector sheet.

For the punching process are on the magnetic cylinder 20 Sheets with punched profile or punching elements applied. These can have a line height of 1 mm in order to be able to punch cardboard up to 350 g / m ² . The respective punched profiles or individual punched segments can be mounted on the surface of the magnetic cylinder without the aid of further tools, so that here an application-specific easy-to-handle change of these is possible. Due to the good accessibility of the magnetic cylinder, such a change is also facilitated.

Magnetic and counter-punching cylinders are ground in particular with a concentricity of +/- 5 microns to their bearings. In combination with the particularly precisely calibrated protector plates on the counter-punching cylinder or laser-cut punched metal sheets on the magnet cylinder, the smallest tolerances for punching, perforating, grooves or grooves etc. can be achieved.

For mutual alignment or addition of magnet and counter punch cylinder sensors are placed in the machine and in particular a digital display to work with a very high accuracy can. For a protector, punching plate change or change of the sheets with the punched profile on the magnetic cylinder, the magnetic cylinder and the counter-punching cylinder can be manually moved forward and backward continuously. This also makes it easy to trim the cylinder to ensure high concentricity. Any necessary trimming by means of calibrated trimming material is easily possible in the μ range. By using the components of a printing machine, combined with a precision bearing, such as a hydraulic bearing, the magnetic cylinder can work with a high force, so that also very good punching results can be achieved. Especially by the use of a hydraulic bearing jumping of the cylinder can be avoided when punching cardboard, which can not be guaranteed at a spring force bearing of the magnetic cylinder. In particular, when grooving and punching of larger cardboard weight weights, therefore, the use of hydraulic cylinders with corresponding hydraulic units or a hydraulic storage of the magnetic cylinder proves to be particularly advantageous.

Basically, it is not only possible to build a punching machine from the printing press, but also, in the printing press while maintaining the printing unit, the magnetic cylinder and the counter-punching cylinder with the corresponding integrate additional components. It is also possible to integrate these two cylinders and the additional components in the printing unit of the printing press. Such an integration of the stamping components into the printing press results in a so-called inline stamping machine.

8th shows a punching and numbering machine 1' , This includes next to the magnetic cylinder 20 and the counter punch cylinder 30 are in the punching and numbering machine 1' a numbering wave 47 as well as an impression cylinder 48 intended. Furthermore, a color box 49 and a squeegee roller 50 in the punching and numbering machine 1' arranged. Between the lifting roller and the numbering shaft, a number of transfer rollers are provided. The numbering shaft is arranged on the bearing thereof instead of a rubber cylinder provided in the former printing machine. An otherwise provided in a printing press plate cylinder is removed or bridged, as this in the punching and Zahliermaschine 1' is not needed.

According to the in 8th shown embodiment of the punching and numbering machine 1' takes place at an imported into the machine sheet first numbering and then only the punching process, the machining direction by the end-side arrow 51 is indicated. In principle, it is also possible first to provide the stamping station as the first station and the numbering or impression station as the second station. Concerning. the punching station is referred to the above remarks for converting a printing press in a punching machine.

In addition to the above-described and shown in the figures embodiments of stamping machines made of printing presses and magnetic cylinders and counter-punching cylinders for this many more can be provided in each of which an at least five years aged frame and a precision bearing are provided for the magnetic cylinder. In the case of the corresponding counter-punching cylinders, protector sheets can be fastened to the counter-punching cylinder by a clamping device.
