  • Patent number: 7950896
    Abstract: A handling apparatus can be used to transfer objects from a first location to a second location along a defined path, without the need for a conveyor along the path. Instead, the handling apparatus can be moved along the path by a controllable transport device, such as a robot arm. The handling apparatus can comprise a plurality of unpowered rollers which are selectively rotated by way of a transfer assist mechanism during loading and/or unloading of the objects to be transferred. The transfer assist mechanism can comprise a separate component that can power the rollers directly or indirectly. The transfer assist mechanism can comprise a belt which imparts rotational force to the support rollers via contact in some embodiments, with the amount of force controlled by varying the relative inclination of the support rollers and the transfer assist mechanism.

  • Patent number: 7509789
    Abstract: A machine (1) for erecting open topped cartons or trays from a substantially flat blank of varying height and footprint dimensions, comprising a magazine 3 adapted to support a supply of flat blanks of predetermined dimensions, a vacuum transfer means for transferring blanks one at a time from the supply to adjustable transfer rails (4)(62)(63) for transferring the blanks to a tray forming section 5, means G for applying glue to the blanks at predetermined locations, the tray forming section 5 including a variable well 6 defined by wall means 11 to 18 which are moveable in two directions to adjust the size of the well and a mandrel 7 having portions 40 to 43 which are moveable in two directions to adjust the size of the mandrel, and a cylinder 45 for pushing the mandrel into the well to fold the blank into a tray, the well being open at the bottom to allow the formed tray to be pushed through the well and onto a conveyor 8 for conveying the formed tray away from the machine.

  • Publication number: 20040005977
    Abstract: A carton forming machine having a blank feeding section (1) which receives blanks from stacked supplies of blanks (10, 11) means (2) for gluing folding and compressing side wall of the blank to form reinforced side walls and end flaps, mandrel means (3) about which the blanks are folded, glued and held to form an open topped carton, the mandrel means including first and second mandrels mounted on a rotating turret (15) and having associated blank holding means (17, 18) the machine being operable to rotate the mandrels when a carton has been formed while the carton is held by the holding means to ensure that the glue sets and to present an empty mandrel about which the next blank is to be folded, thereby ensuring that the throughput of the machine is not compromised while the glue sets.
