Definitions
- the invention relates to a fixed ha Itevorri device for a print carrier according to the preamble of claim 1.
- a Papi trained racing and holding equipment for preventing printing unit damage in the event of paper web tears or Fa Izappa rat damage.
- This device consists of a stationary Lei-shaped clamping piece and an axially parallel and displaceable in the direction of the stationary clamping piece Le s t enf-shaped clamping piece.
- the running paper web is guided through the spaced-apart clamping pieces.
- a control command to actuate cylinder-piston units is triggered by a corresponding control device.
- These cylinder co-planes move the sliding, bar-shaped clamping piece in the direction of the stationary clamping piece.
- the running paper web is held so that machine-damaging pap erbahnwickler are avoided.
- the invention has for its object a switchable holding device for a print carrier in To create printing press.
- the advantages that can be achieved with the invention consist in particular in the fact that a device for holding a printing medium made of paper or plastic from paper or film webs or sheets has been created, which works without sharp-edged or mechanically moving parts.
- the inflatable hose which can be moved in the direction of the paper web and a fixed terminal strip in the event of a malfunction, ensures that the paper web is held quickly and securely, so that damage to the printing or folding unit as a result of winders or stoppers is avoided.
- actuation time of the inflatable tube can be further shortened in that the tube is already biased with a certain air pressure.
- Figure 1 is a schematic representation of a cross section through a holding device in a first low working position and in an indicated intermediate working position.
- Fig. 2 is a schematic representation of a cross section through the holding device in a second higher work position as well as an associated circuit diagram.
- Rotary printing machine continuous print carrier web z. B. paper web 2.
- This crossbeam 4 carries on its lower side a pressure sensor with a clamp body, e.g. B. a gum ie last i see hose 6.
- This hose 6 has on its underside or on the side facing the cross member 4 a hose-fixed skirting board 7 extending over the entire length of the hose 6, the width b of which is greater than an outer one Diameter of the hose 6.
- ends 8, 9 protrude on both sides of the hose cross-section, which ends by means of clamping rails 11; 12 are attached to the cross member 4.
- the clamping rails 11; 12 can e.g. B. be fastened by means of screws 13 to the cross member 4.
- a work surface 14 is formed, which is provided with a friction-enhancing or non-slip material.
- This can also consist of a sc-resistant profile strip 17 with a corrugated clamping surface 20 which extends on the outer circumference in the axis-parallel direction of the hose 6.
- the hose 6 consists, for. B. made of rubber with a fabric insert and the baseboard made of rubber 7. By arranging the fabric insert, the hose 6 has a small height h in a state with a small cross-section together from a first low working position K (FIG. 1).
- the hose 6 has in the working position K is a profile which corresponds to that of a double U arranged in one another.
- the tube 6 has a length that corresponds at least to the width of the paper web 2. At one of the two ends of the hose 6 there is a connecting piece 18 for connecting a pipe 19 for the pressure medium, for. B. compressed air.
- the print medium can also consist of oil or a gel.
- a web break monitoring device 21 for the paper web 2 is arranged, which disturbs the paper transport, e.g. B. detected web break in the printing units or missing copy in the folding unit (Fig. 2).
- Web break control device 21 can, for. B. consist of buttons, photodiodes, sensors or the like ..
- a signal emitted by the web break monitoring device 21 in the event of a fault is sent to a solenoid valve 23 via an amplifier 22.
- the solenoid valve 23 then places between the hose 6 and a central compressed air supply 24, for. B. with a pressure of six bar, a connection.
- the hose 6 is in the shortest possible time, for. B. inflated in a few milliseconds, so that its cross section increases due to the pressure medium in a second higher working position L, that is inflated.
- the hose 6 has expanded in its radial direction, ie in the direction of the diameter d by the amount g + h, so that the profile strip 17 of the hose 6 against the paper web running between the terminal strip 3 and the hose 6 fastened to the crossmember 4 2 is pressed, which leads to the separation of the paper web 2.
- the hose 6 has a multiple of the cross-section previously found in the rest position, so that a second working position L removed from the first working position K is reached.
- a product i ons. B. each arranged behind the printing unit known capture roller then rolls up the separated paper web. The tube 6 turns after the completion of
- hose 6 with its underside or baseboard 7 to the cross member 4 in another way, e.g. B. by gluing.
- terminal block 3 on its side facing the paper web 2 with non-slip material, for. B. rubber to coat.
- the material must have a high coefficient of friction compared to paper or foil.
- clamping strip 3 on its side facing the paper web 2 with a hose 6, which can also be filled with air in its working position parallel to the hose 6 located on the crossmember 4.
- the hose 6 in a low working position K has the cross section of a flat oval.
- Another preferred embodiment variant is the hose 6 during its low first working position K by means of compressed air, for. B. 0.2 to 0.5 bar so that the higher second working position L is reached even faster in the event of damage.
- the solenoid valve 23 is connected in parallel with a pressure-adjustable check valve (FIG. 2).
- the preload of the hose 6 in the first working position K can be straight be so high that its elastic shape at rest does not change (Fig. 1).
- x is z.
- B a natural number between one and ten.
