  • Patent number: 8631924
    Abstract: The invention relates to a conveying device for objects. The device comprises a frame provided with a series of carriers (1) that are movable in a conveying direction, the carriers being aligned parallel to each other with a certain gap and transverse to the conveying direction (A), wherein at least some of the carriers bear pusher shoes (3) that are shiftable along said carriers through the gap. The device is characterized in that the gap between successive carriers is at least partly bridged by gap closure means (50), designed such that a pusher shoe can run through the gap relatively unhindered, while an object other than a pusher shoe is prevented from falling into the gap. The conveying device has less down-time than the known device. The invention also relates to a pusher shoe for use in the device.

  • Patent number: 8069969
    Abstract: A transport device for objects comprises a frame with a series of carriers that run mutually parallel and are pivotally coupled to an endless drivable moving track so as to enable displacement in a direction of displacement. At least some of the carriers comprise pusher shoes with guiding construction that are shiftable along the relevant carriers transversely of the direction of displacement using guide means arranged on the frame. The guiding construction comprises a guide pin with a guide body arranged thereon, wherein the guide pin comprises at least two portions of differing diameter, that the guide means comprise a guide channel in which the guide pin can engage, and that the depth of the guide channel progresses such that, at first engagement, the portion of the guide pin with the largest diameter engages in the guide channel, and with further engagement a portion with a smaller diameter.
