  • Patent number: 8678169
    Abstract: A checkpoint system, wheeled bins for a checkpoint system, and methods for conveying articles in wheeled bins through a checkpoint system. Each bin has four wheels that do not extend below the bin's flat bottom. In this way, the bin can be slid on its bottom along a shallow, troughed divesting table while it is being filled and conveyed on its bottom through a checkpoint and rolled on its wheels along a deeper troughed discharge lane. A bin return beneath the discharge lane returns bins to a bin storage queue beneath the divesting table. A sorter at the output of the checkpoint selectively diverts bins to one or more discharge lanes, such as individual lanes for cleared and for suspect bin contents.

  • Patent number: 6460684
    Abstract: A buffer/brake system is provided for carriers used in an automated assembly system. The rear ends of the carriers are each equipped with a flexible ring that is compressed when an upstream carrier strikes the flexible ring. Compression of the flexible ring causes it to expand and thereby engage the sidewalls of the track and the frictional engagement of the ring against the sidewalls of the track act as a brake for the struck carrier. The ring acts to absorb the shock resulting from the collision between the queued carrier and the oncoming carrier, thereby limiting the transfer of impact forces from pallet to pallet along the track. The ring is carried by a rotatable support which has a laterally extended ring abutment surface. The rotatable ring support is able to swivel, relative to the carrier to which it is attached, as the track makes turns in the assembly system.

  • Patent number: 5409103
    Abstract: A conveyance device is disclosed having a line of members which are held by guide rails, and which include end faces located next to adjacent members. Each member has grooves disposed on opposite sides that extend in the longitudinal direction of transportation for receiving the guide rails and a drive source. Each member includes a bore that passes through the member in the transverse direction to receive an entrainment pin. Each member also includes at least one metal piece extending in the longitudinal direction of transportation that is fixed to at least one plastic part such that an end face of the plastic part projects over the metal piece in the longitudinal direction of transportation, the total length of the member being greater than the total length of the metal piece.

  • Patent number: 5372240
    Abstract: A buffer/brake system is provided for carriers used in an automated assembly system. The rear ends of the carriers are equipped with a flexible ring that is compressed when the queued carrier is struck by an oncoming carrier. Compression of the flexible ring engages the sidewalls of the track support that accommodates the conveyor and the frictional engagement of the ring against the sidewalls of the track support act as a brake for the queued carrier. The ring also acts to absorb the shock resulting from the collision between the queued carrier and the oncoming carrier. The buffer/brake system is fully incorporated in and fixedly attached to the carrier and is not placed on the conveyor separately.

  • Patent number: 5320210
    Abstract: A product-carrying tray 1 has longitudinally slotted end members 3 for sliding engagement on guide rails in a conveyor installation or storage unit. Transverse edges 2 of the tray are provided with coupling members 5 for interengagement with other like units also accommodated on the guide rails. In the illustrated embodiment, the coupling members 5 are defined by interengaging hook structures consisting of projecting portions 7 and laterally extending end portions 6. The tray of the invention is especially suited to accommodating food products within a storage or treatment chamber. The tray may however also serve as a product-carrying element in a conveyor installation. Apart from the hook-type interconnection illustrated, a multiplicity of other interconnecting arrangements may be provided, including, inter alia, alternative mechanical structures and magnetic coupling.

  • Patent number: 5141100
    Abstract: Disclosed is a device to convey parts towards one or more processing stations and to remove them therefrom. This device includes a rail forming a continuous closed circuit and supporting a series of supports which are in contact with the rail by rollers, at least one of which is elastically biased against the rail. Each support is provided, at least at one of its ends, with a ball bearing or roller bearing, by which each support comes into contact with the support that precedes it or follows it. Preferably, the rail has a section with two opposite cants, and it is elastically gripped between rollers having a groove with a shape that matches the cants. Thus, precise positioning is obtained in the transversal direction of each support with respect to the rail, and the ball bearings provide precise contact, with low wear and tear, between two successive supports. This provides for accurate positioning also in the longitudinal direction.

  • Patent number: 5139131
    Abstract: A conveyor installation has a track (3) driven to run endlessly about two deflector wheels (100, 101) and supported by guide rails (1, 1', 2), for the conveyance of workpiece carriers which are designed for instance as boxes to accommodate packagings for liquids. The track (3) has two straight portions (3a, 3b). So that it is possible without any cumbersome dismantling work to clean such an installation thoroughly while at the same time providing accurate guidance for the workpieces being conveyed, positioning them precisely at the processing stations, it is according to the invention proposed that the track (3) comprise, closed in itself, a row of links (4) which have their end faces (16) bearing one on another and in which there are recesses for engagement with the guide rails (1, 1', 2) which support the links (4) in the straight portions (3a, 3b) from opposite sides and in the curved portions (3c, 3d) from outside and in that one workpiece carrier is inseparably mounted on each link (4).

    Abstract: This invention concerns a device for continuous adjustment of a set of workpiece mounts from a number of such mounts in defined work positions whereby the workpiece mounts are arranged with a certain spacing on an endless conveyor device that moves in rotation by increments such that the spacing corresponds to the length of one increment of movement of the conveyor device. Through additional simple adjustment means, the effect is acheived that the set of workpiece mounts in the working position can be adjusted to spacing that differ from the length of one increment of conveyor movement. Then the ork positions thus set are always maintained again in revolution of the endless conveyor device.

  • Patent number: 4710122
    Abstract: The invention relates to a machine for manufacturing flat bodies in a continuous linear process. This is attained by the intermittent forward movement of the moulds on a closed circuit static runway, passing through the various operative steps for forming the pieces. The runway defines a rectangular trajectory and the moulds are square with bevelled vertices forming vertical channels for the actuation of centering elements. The moulds cover the totality of the circuit with the exception of two spaces at the diagonally opposed angles. Each straight section is provided with a pusher facing a buffer for the simultaneous and combined action until each mould reaches the end of the circuit. At a point of the circuit there is a fixed hopper beneath which there reciprocally moves a carriage bearing a metering hopper. Once the pieces have been formed they are removed by a pneumatic extractor having a multiple suction head.
