Definitions

  • embossing blind, relief or hot foil embossing
  • creasing and / or punching operations are performed. It is also known to print, laminate, calender or cut with these devices. The machining process is carried out directly with the lateral surface of the machining cylinder, or the lateral surface is equipped with appropriate tools.
  • sleeve systems In machining tasks with frequently changing requirements such as printing, embossing, creasing or punching so-called sleeve systems are known.
  • sleeves are pushed onto a rotatably driven shaft mounted in the device and locked on this form-fitting or non-positive.
  • the sleeves are released from the shaft and withdrawn.
  • a new designed according to the new task sleeve is pushed.
  • the sleeve is rigidly mounted on the rotatably driven and mounted in the machine frame with bearings shaft.
  • the invention has for its object to provide a device for processing web or sheet material with a rotating drivable machining cylinder, which makes it possible to swap tools quickly and easily and at the same time works without problems at different temperatures.
  • the machining cylinder is designed as a sleeve and pushed onto a fixed axis, which has a supply for compressed air via a journal into the interior, which is connected to outlet openings in the lateral surface, and that a rotary drive is present to which the sleeve can be coupled.
  • the sleeve floats in operation without friction on an air cushion. There are no wear or play bearing bearings required. As a result, lubrication with oil or grease can be omitted without replacement.
  • Various types of machining with an identical basic construction are possible, whereby differently shaped sleeves can be easily replaced.
  • the invention offers particular advantages in machining operations that must be performed at higher temperatures. At a small caused by thermal expansion expansion of the sleeve, only the gap between the sleeve and the axis is slightly increased. Since this gap is filled with compressed air, the running properties of the air bearing are thereby changed negligible. Only the air consumption of the storage increases.
  • the insulating compressed air cushion between the sleeve and the axis prevents excessive heat transfer between these two components. This reduces both unwanted cooling of a heated sleeve and unwanted heating of the axle. The heat input into the machine frame is thereby minimized.
  • sleeve Various materials can be used for the sleeve, in particular metals, fiber composite materials and plastics such as elastomers. Also, heat resistant materials that are less subject to bending are useful, such as ceramics or glass.
  • Figure 1 shows an oblique view of a processing apparatus according to the invention.
  • FIG. 2 shows a view against the product running direction.
  • FIG. 3 shows a cross section through the device.
  • FIG. 4 shows a processing cylinder and its drive in an oblique view.
  • Figure 5 shows a section through the working cylinder
  • Figures 6 and 7 show in an oblique view and side view of the positions before changing a sleeve
  • Figures 8 and 9 show in a diagonal and sectional view a sleeve replacement.
  • the processing device shown in the figures is used for embossing (blind, relief or hot foil stamping) of web or sheet material.
  • Correspondingly designed apparatuses can also be used for the creasing and / or punching of sheets, as well as for calendering, printing, laminating, perforating, breaking and cutting of sheets or sheets.
  • the device includes a machine frame 1, which consists of two lateral uprights 1.1, 1.2 and crossbeams 1.3.
  • a rigid axis 2 is arranged horizontally fixed, which is immovably fixed in each case with their journal 2.1, 2.2 in a stand 1.1, 1.2.
  • a machining cylinder is pushed, which is designed as a sleeve 3 and has an inner diameter that it is frictionless rotatable with minimum gap to the axis 2 at each temperature occurring during operation. In its axial length, the sleeve 3 extends between the uprights 1.1 and 1.2 over the maximum working width of the device.
  • a rotary drive 4 is arranged, to which the sleeve 3 can be coupled to be rotated.
  • the rotary drive 4 consists of an electric motor 4.1, which is fastened to the outside of the stand 1.3 and drives a toothed belt 4.2 via a toothed wheel.
  • each of the two working cylinders 3, 5 is driven by its own engine 4.1.
  • the toothed belt 4.2 rotates via a pulley 4.3 an annular driver 4.4, which is mounted on a bearing, in particular a roller bearing 4.5, rotatably mounted on the drive side mounted axle journal 2.2.
  • the use of an air or plain bearing is also possible.
  • the driver 4.4 is mounted axially adjustable on the journal 2.1.
  • the axial position of the sleeve 3 can be changed without the fixed permanently screwed in the machine frame 1 journals 2.2 is adjusted.
  • the sleeve 3 is coupled torsionally rigidly with one end to the annular driver 4.4.
  • the coupling takes place axially by means of magnetic force, it can also be done by means of vacuum or conventionally with a screw assembly.
  • the entrainment is preferably done by positive locking, which guarantees a positionally correct position and a secure torque transmission.
  • the annular driver 4.4 is axially adjustable with the coupled sleeve 3 in order to adjust the axial position of the sleeve 3 and the tools attached thereto the position of the sheet or web material can.
  • the driver 4.4 is screwed onto an external thread of the axis 2 and can be moved axially by turning.
  • the sleeve 3 rotates frictionless on a compressed air cushion between it and the axis 2, the axis 2 via one of its pins at least one supply 7 for compressed air in its interior, which is connected to outlet openings in the lateral surface, so that compressed air from the lateral surface can escape.
  • the axis 2 includes a plurality of micro-nozzle bores, which are supplied with compressed air and thus form an air bearing within the sleeve 3.
  • a gear drive or a direct drive for example with torque motors
  • a drive system is used which requires no lubrication because of the proximity to the product. So that a sleeve 3 can be replaced by a differently shaped sleeve without removing the axle 2, the stand is 1 .2 designed in two parts, the two parts have a distance from each other, which is slightly larger than the diameter of the sleeve 3. So needs for a sleeve change the journal 2.2 to be solved only by the stand 1.2.
  • the sleeve 3 can be subtracted from the axis 2 and moved between the two parts of the stator 1 .2 from the machine frame 1. Accordingly, a new sleeve 3 can be pushed onto the axis 2 from outside through the upright 1 .2 (FIGS. 5-7). After attachment to the driver 4 and the rigid attachment of the journal 2.2 on the stand 1 .2, the device can start their work.
  • a second working cylinder 5 is mounted in the machine frame 1, which in principle also consists of a rigidly mounted axle and an exchangeable pushed sleeve.
  • the second, in Figure 1 lower working cylinder 5 is driven by a common or its own rotary drive 4 with motor 4.1 in opposite directions to the working cylinder 3.
  • the web or sheets are moved for processing between the working cylinders 3, 5.
  • At least one of the working cylinder 3.5 is mounted vertically adjustable in the machine frame.
  • the upper working cylinder 3 can be fixed in different height positions.
  • the lower cylinder 5 is mounted in height adjustable.
  • the working cylinder 5 is a smooth counter-cylinder without its own tools. However, he can also wear on his outer surface own tools to edit a sheet or a web at the same time at the top and bottom.
  • the construction according to the invention makes it possible to work with very different tooling or machining systems.
  • changing the processing only needs the removable sleeve 3 or 5 to be changed in construction and diameter.
  • the functional basis (bearing of the journals, clamping, drive) can remain unchanged.
  • the sleeve 3 can also work together with a moving flat counter surface. Then, the sleeve 3 or the mating surface carries the tools, and the sheet or web to be processed is guided between the sleeve 3 and the mating surface.
  • the invention has the further advantage that the deflection under load is considerably reduced by the rigid, non-rotatable clamping of the axle 2 in comparison to conventional machining cylinders which are rotatably mounted via roller bearings
  • the deflections of the working cylinders can be substantially reduced compared to conventional systems, which is of particular advantage in applications which place very high demands on the axis parallelism of the two working cylinders 3, 5.
  • the axis 2 contains at least two rows of nozzles 7, which are individually controllable.
  • the individually controllable rows of nozzles make it possible to form different pressure zones in the axial direction in order to set the desired rigidity in the zones, in particular in the case of a thin-walled design of the sleeve 3. Since the axis 2, not the sleeve 3, is the bearing element, the rigidity of the sleeve has 3 hardly affects the system stiffness.
  • suction or compressed air can also be brought from inside to outside onto the sleeve 3 through the air ducts. With suction or compressed air, products or parts thereof can be sucked in or blown off for removal, feeding or application.
  • a great advantage is that devices according to the invention can be assembled into systems in which different processing methods are carried out successively.
  • a change of a machining process or the order of processing can be done simply by a change of the sleeves.
  • Such processing methods are, for example, printing followed by smoothing calendering, or hot foil stamping followed by blank stamping.
  • the device is particularly suitable for machining operations in which high temperatures of, for example, 300 ° C arise.
