Definitions

  • the invention relates to a piston-cylinder device with automatic shutdown, a vacuum holder and a vacuum support table.
  • pneumatic piston-cylinder devices for handling workpieces is generally known in the prior art. These can for example be designed with a blowing or suction function in order to hold workpieces or to convey them with compressed air.
  • the overpressure or underpressure provided by an external pressure device is usually controlled via a separate switching valve, which creates a correspondingly high pneumatic and control-related interconnection effort.
  • vacuum tables for temporarily holding flat workpieces in a stationary manner by means of negative pressure.
  • Such devices are used to temporarily fix the workpieces at individual processing stations as part of a manufacturing process, for example for machining steps such as grinding, drilling, sawing or milling or, for example, also for gluing or joining components.
  • Such vacuum tables usually consist of a central negative pressure source, for example a vacuum pump, and a support surface through which suction bores or suction holes are penetrated, which are in permanent fluid connection with the negative pressure source. Since the negative pressure is permanently available regardless of the function, the operation is relative energy consuming.
  • there is a technical challenge in adapting the active area of the vacuum table to the shape and dimensions of the workpiece to be held. In practice, it is known to cover bores or suction holes that remain free with adapter mats, which, however, have to be specially adapted to the shape of the workpiece to be machined and the desired machining geometry.
  • the GB 892,771 discloses a work table for handling workpieces, in which several vacuum holders are integrated, each of which is formed from a piston-cylinder device with a suction head.
  • the suction heads are arranged within holes in the plate of the work table and are arranged at the upper end of a hollow piston rod, which is formed at its lower end with a piston which is arranged axially movable in a cylinder housing.
  • the suction heads can each be extended via a pressure connection opening into the lower cylinder chamber and can be connected to a vacuum pump and subjected to a negative pressure via a separate pressure connection of the hollow piston rod.
  • the one from the GB 892,771 disclosed device does not disclose any means for controlling the pressurization with a negative pressure.
  • the hollow piston rods are permanently subjected to negative pressure during operation, regardless of the stress on their function. Since the hollow piston rod is firmly connected to the piston and can therefore only be moved together with it, the pressure connection of the hollow piston rod must be designed to be flexible and is subject to material wear due to the movable connection.
  • the DE 10 2004 025 781 B4 discloses a vacuum gripper with a mouthpiece which can be acted upon by a negative pressure source and which is connected via a hollow piston rod to a piston of a piston-cylinder device.
  • a control valve for controlling the energy provided by the vacuum source is integrated into the piston-cylinder device, which control valve controls a first action which moves the mouthpiece and a second action which applies a vacuum to the mouthpiece. That of the DE 10 2004 025 781 B4 disclosed in the piston-cylinder device
  • the integrated control valve is functionally built with a large number of individual parts, which is relatively expensive and complex.
  • D1 discloses a piston-cylinder device with a suction pipe which is statically arranged in the cylinder housing and a piston which is arranged axially movably thereon and which is formed with a suction head which is arranged outside the cylinder housing.
  • the suction function is controlled by a separate external control device.
  • the DE 22 49 412 A discloses a piston-cylinder device in which a suction pipe arranged axially movably in a cylinder is formed with a suction nozzle.
  • the device further comprises a lifting sleeve which is arranged axially movably on the cylinder.
  • the control of the travel path of the components of the piston-cylinder device and the provision of the suction air are carried out via an external connection.
  • the one from the DE 22 49 412 A disclosed piston-cylinder device with suction function is functionally built with a large number of individual parts relatively expensive and complex.

  • a piston-cylinder device with a blower or suction function that can be switched off is to be provided, which is constructed as simple and compact as possible in terms of design, can be produced simply and inexpensively and enables energy-efficient operation.
  • the essence of the invention is a piston-cylinder device with a dispensing means arranged outside the cylinder housing, in which a suction or pressure pipe which can be brought into fluid connection with a pressure device is provided, which is statically arranged in the cylinder space and on which an axially movable piston with a hollow piston rod is slidably mounted, wherein the hollow piston rod is arranged on the head side of the piston and formed or connected to the dispensing means, and wherein the hollow piston rod or a pipe section connected to it is formed below the dispensing means with an inner sealing plug which, in the retracted position of the hollow piston rod, closes a head-side opening of the suction or pressure tube in a form-fitting manner and releases it with the extension movement of the hollow piston rod, at the same time a fluid connection can be established between the delivery means and the suction or pressure pipe.
  • a pressure device for use with the piston-cylinder device, depending on the desired function (blowing or suction), a pressure device providing positive or negative pressure comes into consideration, as either a compressed air source, such as a compressor or compressed air reservoir, or a negative pressure source, for example a vacuum pump.

  • the delivery means is indirectly connected to the hollow piston rod via the separate pipe section, which is arranged between the delivery means and the hollow piston rod.
  • the dispensing means can likewise be screwed onto the pipe section or screwed into it with a threaded attachment.
  • the cross-sectional area of the stopper or of a projection formed by the stopper is designed to be smaller than the inside diameter of the hollow piston rod or the tube section, and the stopper closes the head-side opening of the suction or pressure tube in the retracted position of the hollow piston rod with a positive fit by engaging them either flush at the front, or by engaging flush with the periphery with a shoulder, or by being designed with a hollow cylindrical shoulder that engages flush around the head-side end of the suction or pressure pipe.
  • the sealing plug is arranged in the hollow piston rod in such a way that the operating fluid can flow around it within the hollow piston rod.

  • both pressure medium connections can be operated with the same pressure and the uncontrolled pressure medium connection can be operated permanently be acted upon.
  • the piston moves in this case against the simultaneous permanent pressurization of the other cylinder chamber due to the larger pressurizing surface of the piston that interacts with this cylinder chamber. This enables a considerable simplification of the pneumatic interconnection of the piston-cylinder unit.
  • both pressure medium connections can be controlled jointly via a 5/2-way valve, in whose switching positions the two cylinder chambers can alternately be acted upon and vented.
