Definitions
- the invention relates to a device according to the preamble of claim 1.
- Suction belt tables consist of a box-shaped cavity over which the Suction belts are guided. Suction belts are provided with openings Flat ribbons.
- a suction air supply is arranged on the underside of the belt table. This can be as simple fan or fan connection.
- the suction belts of a wave driven and held in a straight position by a clamping device are usually on a suction belt tables.
- the suction belts are, for example, suction belt tables at the known ones tensioned by means of spring tensioned rollers. This facility is below the Suction belt table arranged and difficult to reach for operation.
- the aim of the invention is therefore to improve the suction belt table so that the Sheet transport can be designed safely in a simple manner.
- the object of the invention is a generic suction belt table such to further develop that the sheet transport is designed safely in any operating situation and can be readjusted, in particular an automatic setting the suction air requirement of the front chamber is desired.
- the device according to the invention has great advantages in relation to the Regulating and influencing the transport safety of sheets on the Suction belt tables, especially when the sheets run off from Suction belt table have advantages in that an excessive Vacuum is avoided by stopping the suction belts on the suction belt table can leave.
- FIG. 1 part of a suction belt table is shown.
- the suction belt table contains a main suction box 1 over which suction belts 7 are guided.
- the Main suction box 1 has a suction chamber 2, the top side of which by perforated cover plate 3 is limited.
- openings 4 are Passage of suction air provided.
- the suction air acts through the openings 4 Print sheets that are guided on the suction belts 7.
- a suction chamber 9 is provided, which has more Openings 4 is also connected to the suction belts 7.
- the suction belts 7 are moved over pulleys 8 at the end of the table, i.e. beyond the main suction box 1 guided.
- the suction chamber 2 is also with a suction nozzle 5 and with this connected to a fan 6.
- auxiliary suction pipe 12 continues to connect in the suction nozzle 5.
- the auxiliary suction pipe 12 acts as an injector nozzle for additional suction. Functionally, the mode of operation is comparable to a jet pump. Therefore, the auxiliary suction pipe 12 opens into a bend, the suction opening of which faces the fan 6. When pressure is relieved by the suction belt table running free, an increased flow arises in the area of the auxiliary suction pipe 12, which builds up a negative pressure in the auxiliary suction pipe 12.
- the auxiliary suction pipe 12 is connected to the suction chamber 9 via a pipe 10 with a connection 11 and the suction chamber 16. Additional ventilation is provided in the area of the pipe 10.
- the additional ventilation is formed by a ring 13, which is provided with openings 14, which in turn correspond to openings 15 in the tube 10.
- a ring 13 which is provided with openings 14, which in turn correspond to openings 15 in the tube 10.
- FIG 2 the entire arrangement is shown from the top.
- the suction nozzle 5 is shown, into which the suction pipe 12 projects.
- the pipe 10 connects the suction nozzle 5 to the suction chamber 16 in the suction belt table via the Pipe connection 11.
- the auxiliary ventilation is not shown in this case. about the top of the suction belt table, which is formed by the cover plate 3 and is pierced by openings 4, the suction belts 7 with their Suction openings led.
- the suction belt table with its main suction box is 1 in Shown top view and has a first arrangement of cavities 2. in the front area of the suction belt table, i.e. in the area where the arches from Suction belt table run, an additional suction chamber 9 is provided.
- the Suction chamber 9 is connected to suction chamber 16. Furthermore, the suction chamber 9 via openings 17 with the suction space 2, i.e. the main suction box 1 connected.
- the suction belts are placed on the front of the suction belt table Deflection rollers 8 out.
- FIG 3 is a detail of the connection between the suction chamber 9 and the Suction chamber 2 shown in more detail.
- an opening 17 in the Wall between the two cavities 2, 9 closed with a ball 9 become.
- the ball 9 settles in the manner of a check valve for example under spring force in the seat of the opening 17.
- the Ball 9 also have a seat on both sides, so that overpressure regulation can take place between the two cavities 9 and 2.
- the ball 9 can do this against the respective seat by means of a weak spring, which additionally according to a desired overpressure in its preload can be adjustable.
- FIG 4 is a variation of the closure previously described shown between the two cavities 9 and 2.
- the opening 17 is shown between the cover plate 3 and the main suction box 1.
- the opening 17 can through a flap 18 can be closed.
- This flap can be sprung in such a way that they are under an overpressure effect from the side of the suction chamber 9 can be opened. This also applies to an increased vacuum on the Side of the suction room 2.
- the arrangement thus ensures that, for example, when the suction belt table runs empty and there is a pressure increase in the main suction box 1, an undesirable pressure increase or vacuum reduction in the suction space 9 takes place. This could, if necessary, jeopardize the operational safety of the suction belt table when the last sheets run off, which could then no longer be conveyed properly.
- the suction space 16 as a common suction chamber, the air duct to the suction chambers 9 in the end area the suction belt table takes over, the openings 17 of the respective a suction space 9 assigned to a suction belt 7 also directly with the suction space 2 be connected via the pressure compensation devices.
- the Pressure equalization processes can then even be page by page independent run from each other and improve the functionality of the Suction belt table additionally.
