Definitions
- the invention relates to an arrangement for emptying and filling a hose to which working fluid can be applied in accordance with the preamble of claim 1.
- GB 2 283 062 A shows a device for filling and emptying a cushion with a pressure medium. The discharge takes place via a throttle using the ejector principle.
- the invention has for its object to provide an arrangement for emptying and filling a hose to which working fluid can be applied.
- a hose used to hold or clamp objects can be completely emptied in a very short time.
- This is advantageous e.g. B. when supplying folded printing plates to a forme cylinder through a feed shaft of a feed device, in which the bent ends of the printing plate are temporarily clamped to the shaft wall by filled hoses.
- the hoses lie completely flat after emptying the filling medium or the working fluid. This increases the length of the possible working stroke.
- This is particularly advantageous for dimensioning the clear width Transport shaft for conveying pressure plates that are folded at the end, in which hoses are arranged as clamping elements that can be actuated by pressure medium.
- Fig. 1 shows the schematic diagram of a circuit arrangement for quickly emptying hoses filled with working fluid in the filling position of the hose.
- Fig. 2 shows a schematic diagram analogous to Fig. 1, but in the emptying position of the hose.
- An actuator 01 e.g. a shape-changeable hose 01 is connected via a feed line 02 to a pressure source 03 for a working fluid, e.g. B. gas, especially compressed air.
- a working fluid e.g. B. gas, especially compressed air.
- a first directional valve 04 z. B. a three-way valve
- a second directional valve 06 z. B. a five-way valve arranged.
- the second directional valve 06 has a connection for a line 07, which expediently ends in a throttle valve 08 with a downstream silencer 09.
- the second directional valve 06 is connected to the first directional valve via the feed line 02.
- the first directional valve 04 has a connection for a first line 11, which in turn is connected directly to the throttle valve 08.
- a pneumatically actuable control line 12 branches off from the outlet line 07 leading from the second directional valve 06 and switches the first directional valve 04 against the force of a return spring when compressed air is applied.
- hose 01 and the directional control valves 04; 06 in filling position A ie hose 01 is filled with compressed air coming from pressure source 03.
- the cross section of the tube 01 changes and becomes approximately circular or oval, depending on how much space in a channel z.
- the second directional control valve 06 switches to the emptying position B (FIG. 2).
- the compressed air coming from the pressure source 03 is fed through the valve position of the second directional valve 06 to the second line 07, the compressed air being blown off into the open via the throttle valve 08 and the silencer 09.
- the control line 12 branching off from the outlet line 07 is pressurized with compressed air, so that the first directional valve 04 switches to the emptying position B.
- the hose 01 is sucked empty via the first line 11, which is activated by the first directional valve 04, in that the air to be extracted is supplied to the throttle valve 08, which is pressurized with compressed air by the pressure source 03, for inflation via the silencer 09.
- the working fluid from the pressure source 03 has a positive differential speed compared to the working fluid from the hose 01.
- Positive differential speed means that the working fluid from the pressure source 03 has a higher flow speed than the working fluid from the discharge line 11 (ejector principle).
- the hose 01 is therefore emptied via the throttle valve 08 and when the hose 01 is filled, the throttle valve 08 is bypassed, ie. H. line 02, bridged.
- a liquid can also be used as the working fluid, such as e.g. B. oil and the like, which is then collected after the escape from the throttle valve 08 or from the silencer 09.
- high pressure e.g. B. three to six bar
- flowing through the feed line 02 pressure medium for. B. compressed air is able to entrain the compressed air escaping through the discharge line 11 in the direction of the Dall damper 06 or air outlet.
- Both versions are understood to mean a device 08 operating according to the ejector principle.
