Title: Apparatus for automatic insertion of valved bags on bag-filling machines for materials in granular powder or like form
IPC: B65B43/26
Filed: 1977-03-29
Abstract: 1524170 Bag filling machines VENTOMATIC ITALIANA Srl 29 March 1977 [6 May 1976] 13139/77 Heading B8C Apparatus for automatically applying a valved bag 29 on to the nozzle 44 of a filling machine comprises a bag valve-testing probe 34 carrying a sensor 35, which, on failure of the probe to enter a defective bag valve, initiates actuation of a roller mechanism 45-49 to discard the faulty bag. Bags are sequentially fed form a roll or from a stack 9 by a reciprocating suction gripper 8 on to a feed conveyer 1. A pivotal element 10 grazing the conveyer deflects a bag, valve end uppermost, between a pair of continuously driven belts 13, 13<SP>1</SP> and movable presser rollers 15, 16 which carry the bag upwards until its top reaches a stop device 17, e.g. photocell. This device causes the pivotal element 10 to swing away from the feed conveyer the presser rolls to lift from the belts 13, 13<SP>1</SP> and the bag to be slidably-clamped between a pair of holder jaws 18 and 19. A further pair of vertically-movable jaws 24, 25 are actuated to grip the bag and pull it downwardly to spread its upper end against the holding jaws. A suction gripper 30 is reciprocated to partially open the bag valve. The probe 34 is then moved into the valve causing it to open completely. On entry of the probe, the sensor 35 is actuated by the upper lip of the valve to cause a pair of arcuate jaws 21 and 22 to grip the bag and carry it laterally on to the filling nozzle after the probe has been swung back to its inoperative position, Fig. 9 (not shown). Should a defective bag valve inhibit entry of the probe, the roller mechanism 45-49 is actuated to discharge the bag in a direction away from the nozzle. Several such bag-applying devices may be arranged above the feed conveyer, each associated with a respective one of several bag-filling nozzles. Instead of being disposed at a fixed location, the device(s) may be arranged to move in rectilinear or circular paths.
