Apparatus and method for pneumatic or gaseous catapulting of items in bulk and production method thereof

Abstract

The following describes a device for the pneumatic or gas-operated catapulting of loose objects, in particular objects attached to a rope, in particular a cloth bag, with an accelerating tube, a pressure chamber, an initial operable expansion valve and a second load valve, whereby the accelerating tube is attached to one end of a fluid line from the expansion valve as an extension and the pressure chamber is designed on the opposite end of the fluid line as an extension, the load valve is designed in the direct fluid connection with the pressure chamber, whereby the catapultable object can be placed and/or inserted loosely into the barrel of the accelerating tube, in front of the expansion valve.

1 . Device for the pneumatic or gas-operated catapulting of loose objects, in particular of an object attached to a rope, in particular a cloth bag, with an accelerating tube, a pressure chamber, an initial operable expansion valve and a second load valve, whereby the accelerating tube is attached as an extension to the end of a fluid line from the expansion valve and the pressure chamber attached to the opposite end of the fluid line as an extension, the load valve is designed with a direct fluid connection to the pressure chamber, whereby the catapultable object can be inserted and/or placed loosely in the barrel of the accelerating tube in front of the expansion valve. 
     
     
         2 . Device according to  claim 1 , characterised in that the pressure chamber is designed as a metal tube with a sealable lid, in particular with a sealing tape. 
     
     
         3 . Device according to  claim 1 , characterised in that the operable expansion valve is designed as a ball tap-ball valve, in particular electrically activated, or more preferably manually controllable. 
     
     
         4 . Device according to  claim 1 , characterised in that the accelerating tube and the pressure chamber are identical tubes, in particular the device is manufactured wholly of plastic materials, in particular PVC, or more preferably wholly of metal. 
     
     
         5 . Device according to  claim 1 , characterised in that the ball tap-ball valve is manufactured with an opening for the load valve preferably designed as a thread. 
     
     
         6 . Device according to  claim 1 , characterised in that the load valve is an auto valve, which can preferably be screwed onto the fluid line adapter of the expansion valve. 
     
     
         7 . Device according to  claim 1 , characterised in that the expansion valve is integrated as a fluid line adapter with a T-shape with two openings, one for the pressure chamber and the other for the accelerating tube and the load valve can be screwed into the fluid line adapter between the accelerating tube and pressure chamber. 
     
     
         8 . Method for manufacturing a device, in particular according to  claim 1 , for the pneumatic or gas-operated catapulting of loose objects, preferably manufactured from plastic materials, in particular metal, whereby a sealing lid being a pressure chamber, impermeable to fluids, is screwed onto a tube, in particular with standardised threads on both sides, on the opposite side an integrated ball tap-ball valve is mounted, whereby the ball tap-ball valve is mounted with a direct line to the pressure chamber and an accelerating tube is mounted opposite in the extension of the ball tap-ball valve and a load valve, in particular an auto valve, impermeable to fluids,is mounted on the pressure chamber. 
     
     
         9 . Method for catapulting a loose object with a controllable force, in particular with a rope attached, in particular by means of a device according to  claim 1 , whereby, in a pressure chamber, a fluid, in particular air, is filled and compressed by a load valve manually or more preferably by means of a compressor, in an accelerating tube, a loose object for catapulting is placed or inserted in front of an expansion valve and, by opening the expansion valve manually or electrically, the object is catapulted by expansion of the fluid, whereby the acceleration force is controlled by the opening angle and the opening speed of the expansion valve, in particular a ball tap-ball valve. 
     
     
         10 . Method according to  claim 9 , whereby the pressure chamber g-is subjected to a pressure of at least 10 bar, more preferably 15 bar, still more preferably 20 bar, in particular using a conventional bicycle pump and/or a conventional auto valve compressor.
