Definitions
- Printing machine with a device for detecting the presence of an application form and a method for applying an application form
- the invention relates to a printing press with a device for detecting the presence of a printing form according to the preamble of claim 1 and a method for applying an application form according to the features of claim 19.
- the printing plates intended for printing are positioned in the automatic plate changing machines and, after a printed printing plate has been removed from the cylinder carrying the printing plate during the printing process, fed to the latter.
- a clamping unit that receives and fixes the front edge of the printing plate and a clamping / tensioning unit that receives and fixes the rear edge of the printing plate and subsequently tensioning the printing plate are provided.
- the clamping unit is assigned alignment pins which are arranged at a distance from one another and which correspond to alignment punchings provided in the front edge of the printing plate.
- the clamping unit and the clamping / tensioning unit are opened and the printing plate is placed against the locating pins with the fitting punching.
- the cylinder is rotated against the printing direction and the rear edge of the printing plate is brought to the clamping / tensioning unit, with means being provided which bring the printing plate closer to the jacket of the cylinder and position the free rear edge of the printing plate in the clamping / tensioning unit.
- the clamping / tensioning unit is then closed and tensioned on the cylinder by moving the pressure plate in the circumferential direction.
- the holding device has a front and a rear fastening device, with pneumatic means in particular often being arranged for clamping the application form.
- Application forms and / or printing forms and / or printing plates are used in various printing processes, such as, for example, planographic printing or letterpress printing, in particular flexographic printing, or gravure printing.
- planographic printing or letterpress printing in particular flexographic printing, or gravure printing.
- flexographic printing the printing form and / or the flexographic application form has several raised areas.
- Flexographic application forms usually consist of a flexible base body, for example a polymer film, which has a thickness that is between 0.2 mm and 1 mm, for example.
- a bar is preferably arranged, which consists of a plastic material, for example. This is used to fasten the application form in appropriate fastening devices.
- a covering is preferably applied to the base body at appropriate points, for example a rubber covering.
- a layer and / or a covering is removed so that a relief is created.
- the carrier material in such application forms is, for example, a plastic.
- a holding device for printing plates is known from EP 0308 799 B1, which has a clamping and tensioning device, two fastening devices being directly connected to one another via articulation levers.
- a device for detecting the position of a printing plate is known from DE 102008054811 A1.
- DE 102015200 148 A1 discloses a printing press and a method for correcting at least one length of a printing area.
- a fastening device with several tensioning elements for tensioning a cylinder elevator is arranged in a cylinder channel or the cylinder recess.
- the position of the clamping elements or of the cylinder elevator with respect to an axial direction can be changed by means of displacement means.
- the change in position of the clamping elements and / or the expansion of the cylinder elevator can be measured by a sensor designed as a camera.
- DE 102006056 831 A1 discloses a printing machine with forme cylinders with cylinder channels and holding devices for fastening / holding a printing plate. When the printing plate is placed, it is aligned in the page register by means of an alignment device. A contactless sensor checks whether a suspension leg of a pressure plate has actually come loose after actuation of a holding means of the holding device.
- the invention is based on the object of creating a printing press with a device for detecting the presence of an application form and a method for applying an application form.
- the advantages that can be achieved with the invention are in particular that the presence of an application form on a forme cylinder is detected by means of a sensor.
- the sensor designed as an optical sensor is in particular also able to detect the presence of non-conductive or poorly conductive materials.
- application forms can be recognized which, for example, are at least partially made of plastic.
- the sensor can also use transparent and / or shiny materials, for example through the use of polarized light and / or recognize surfaces.
- One advantage that can be achieved with the invention is that a plate changing device has been created for a coating unit in a printing press. In particular, this is possible through the use of an optical sensor. In particular, such a plate changing device increases the productivity of a printing machine and / or a painting machine.
- a method for applying an application form to a form cylinder can be operated more reliably and independently of the materials used by using the optical sensor.
- the senor is arranged in particular on the forme cylinder in such a way that little additional space and / or installation space is required.
- the sensor is preferably arranged in the cylinder channel and designed as a light scanner.
- the transmitter and receiver are preferably arranged and designed in parallel and in one piece, which means that less installation space is required.
- parallel refers in particular to an arrangement of transmitter and receiver lying next to one another in the fastening device or in the forme cylinder. Both are preferably at the same level and below a lateral surface.
- the transmitter and receiver can be inclined.
- the at least one sensor is preferably arranged and / or sunk in the front fastening device.
- countersunk is meant here, in particular, countersunk in the cylinder channel, as a result of which the sensor does not protrude from this. In particular, it does not protrude beyond the surface area of the forme cylinder. In particular, no additional installation space outside the forme cylinder is then necessary. There is no need for a sensor on the housing or outside the forme cylinder.
- no counterpart, in particular no receiver is required on the housing.
- the receiver is also arranged in the forme cylinder, more preferably on the front fastening device.
- Another advantage that can be achieved with the invention is that the at least one optical sensor is arranged close to the at least one alignment element. In particular, this ensures that the application form then rests against the at least one alignment element. In particular, it is then possible to dispense with contacts on the at least one alignment element.
- the position of the flexographic application form on the forme cylinder can also be recognized by the arrangement of the at least one sensor.
- this can be achieved, for example, in that the sensor, for example, scans an area and detects the position of the edge in the area.
- this signal can be used to readjust or readjust the fastening system, for example. Based on this signal, it is also possible, for example, to align the order form.
- the at least one reflex scanner is preferably arranged close to the alignment mark or the dowel pin. This means that the application form can be reliably identified.
