Abstract
Description
- Universal Equipment for Filling Valve Bags.
- The invention relates to universal equipment for erecting, filling and sealing valve bags, consisting of a bag storage magazine, a bag supply device, a device provided with a beak for opening and forming the valve, an erecting device for transferring the empty bag off the beak to a filling tube of a filling device, and a sealing device for sealing the valve.
- The explicit aim is to render equipment for completely automatically filling and sealing both paper and plastic valve bags in various embodiments, i.e. sealed, as well as glued, block bottom and sowed, and with various filling systems, both induced by gravity (filling tube), with air transport or mechanical transport (e.g. a propeller). By applying single or multi-walled sealed plastic valve bags, so-called sole-bags or pinch-bottom valve bags respectively, a completely sealed packing is obtained, complying with Bundesbahn, UN specifications respectively, for granular or powdered products up to hazard class 8 (Caustic soda NaOH and the like).
- Particularly the fact that during filling no personnel has to come near the machine is an important advantage of the present invention. One of the main characteristics of the invented equipment is, that the filling device is providedwith a turntable which can be rotated by a a filling tube position-changing device about a centre line enclosing an angle in the order of 45° to the horizontal in a filling tube perpendicular plane of the equipment, said turntable carrying two or a multiple of two filling tubes, each fillng tube extending substantially horizontally in the erected 'position and substantially vertically in the filling position.
- With said measure, a gain of time is obtained in the working of the equipment, since it is as if an interim station has been put between erecting and filling. In view of processing substances which are health-hazardous, it is also of major importance that the filling opening is as good as only open if a bag is suspended from the filling tube. In the invented equipment, this moment only occurs when the bag is released and the moment when the turntable rotates, during which it is of major importance that the filling opening is sealed by the disc.
- Preferably the turntable and a substantially equally large stationary disc are rollingly associated and adjacent to a supply tube a seal has been applied in the stationary disc which frictionally engages the turntable.
- The beak of the erecting device in plan view is adapted to follow a substantially rectangular path, wherein it remains constantly parallel to itself. This can be attained due to the fact that the beak has been mounted in a beak frame and is displaceable in three mutually perpendicular planes in order to transfer the bag to the erection clamp which is reciprocable in the erection clamp perpendicular plane.
- Preferably the sealing device is provided with a sealing member having a discharge valve. The filling device can also be provided with a bag seat, the bottom of which encloses an angle to the horizontal, and if the discharge valve slopes downwardly towards a bag discharge chute, a shunting hill-resembling device is obtained which causes the filled bags to come out on account of the gravity.
- In an efficient embodiment the filling tube perpendicular plane encloses an angle of about 30° to an erection clamp perpendicular plane of the erecting device. With this measure, space-saving of the entire equipment is obtained.
