  • Patent number: 11970348
    Abstract: A palletizing elevator is provided that lowers gradually a pallet thereon from an upper level as it is filled with products, and by providing an empty pallet infeed system that moves empty pallets towards the palletizing elevator simultaneously to the palletizing of products thereon. The empty pallet infeed system includes an empty pallet elevator for raising empty pallets to the upper level and a conveying system between the empty pallet elevator and the palletizing elevator for moving the empty pallets of from the empty pallet elevator at the upper level to the palletizing elevator while a pallet is moved by the palletizing elevator during its filling.

  • Publication number: 20240132304
    Abstract: A vision-assisted robotized depalletizer receives at a pallet station a pallet loaded with products and outputs on a conveyor unitized products aligned in a desired orientation. Such depalletizers include a vision system having one or more image acquisition sensors that are positioned relative to the pallet station so as to have a field of view covering a top portion of the pallet. The sensors send to a controller one or more image of the top portion of the pallet that the controller uses along to determine the position of each product in the top portion of the pallet. The depalletizer further includes a robot equipped with a depalletizing tool that is coupled to the vision system controller for receiving information indicative of the position of each product from the top portion and uses that information to pick and position on the output conveyor each product from the top portion.

  • Publication number: 20240116723
    Abstract: The problem of potentially damaging a pallet layer that is gripped by clamps of a depalletizing tool is solved i) by detecting the real position of the layer using a pad on the tool that is movable with the clamps towards the pallet layer and whose detected stopping position determines the real position of the layer, and ii) while the layer is gripped by the clamp, by inserting under the layer curtains; the pressure on the layer by the clamps being adapted to the ease to go underneath the layer.

  • Publication number: 20230010402
    Abstract: A method of inspecting cased goods includes advancing at least one case of goods on a conveyor, generating an illumination sheet of parallel illuminating rays with at least one electromagnetic source, and capturing an image, formed by the illumination sheet passing through a diffuser with at least one camera located so as to capture illumination from diffused parallel rays of the light sheet, where the image case embodies a goods image that is generated by the case goods moving between the light source and the at least one camera, where part of the parallel sheet of light is at least partially blocked by the case of goods, thus generating a gray level image.

  • Publication number: 20220388163
    Abstract: A tool, for palletizing mixed load products, includes a frame for mounting the tool to a robot, a support assembly having a support member forming a support surface disposed in a predetermined reference orientation so as to support product, and a gripping assembly, mounted to the frame, with an actuator and a grip press operably coupled to the actuator so as to move the grip press relative to the frame in an actuation direction opposite the support surface so as to clamp the product between the support surface in the predetermined reference orientation and the grip press. The support assembly coupling to the frame has a configuration fixing the support member relative to the frame in the actuation direction with the support surface in the predetermined reference orientation, and is movably released in at least another direction so that the support member is movable away from the predetermined reference orientation.
