  • Patent number: 9925713
    Abstract: A synchronous running safeguard for transfer stations or devices for handling containers, in particular for handling bottle-like containers made of glass or plastic, having a first and a second rotary element, which each have holding elements for the containers and each have a motor drive. The rotary elements are disposed in relation to one another such that the containers can be transferred in a transfer area from one of the first holding elements to one of the second holding elements. The rotary elements, each rotationally connected, have a control element having engagement elements, and the control elements are in meshing engagement with one another. The control elements are disposed in such a way that, during operation the control elements are interengaged without contact during the rotary movement of the rotary elements and that, in the event of a fault, the control elements are interengaged with contact.

  • Patent number: 8322288
    Abstract: The invention presented comprises an operation system in which items to be processed by an operator, such as a washer/dryer, bulk sterilizer, or kiln, are fed into and removed from the operator by a continuous conveyor. A microcontroller controls actuators in loading zones distributed along the conveyor that switch the individual loading zones from bypass to push mode to alternately allow the items to remain stationary on the moving conveyor or be moved to a downstream loading zone when in the push mode. In a preferred embodiment, at least one loading zone is located at least partly within the operator.

  • Patent number: 6659897
    Abstract: A chain drive assembly for elevating a load such as a vehicle carriage on a leisure ride. The assembly comprises an endless loop lift chain and a plurality of drive chains. The lift chain has a plurality of chain links comprising a pair of laterally spaced outer link plates pivotally connected to inner link members disposed at least in part between the outer link members. The inner or outer link members of each link have a row of teeth for engagement in openings between links of the drive chains. The drive chains being disposed so as to engage the teeth at a rectilinear stretch of the chain loop so as to drive the chain in a longitudinal direction. The inner and outer links of the lift chain being arranged to define an opening designed to receive a projection on the load. The assembly serves to spread the load between the drive chains and their drive systems. The conveyor chain does not articulate under load and can be reduced in weight.

  • Patent number: 6553916
    Abstract: The present invention provides a low clearance, compact guideway, train positioning system that can be installed in close quarters alongside an existing railroad track. The system is chain driven and features an improved over/under or vertical sprocket carriage drive system in which parts normally exposed to the elements are protected while, at the same time, horizontal space requirements alongside the track are reduced. The system employs a vertically oriented chain drive which employs enclosed vertically mounted drive and idler sprocket units and a chain tube enclosing the lower chain strand which further minimizes exposure of the mechanism chain to the elements by totally enclosing the lower chain path in the over/under arrangement.

  • Patent number: 6435099
    Abstract: A powered pushing unit transfers ads no greater than a predetermined magnitude in one direction along the length of a load transfer system. The pushing unit includes a frame and a source of power for moving the pushing unit back and forth along the length of the load transfer system. A dog for engaging a load is pivotally mounted with respect to the frame. A restricting mechanism applies a load engaging force to hold the dog at a load transfer range of positions until the load is greater than the predetermined magnitude. A toggle joint is mounted between the dog and the frame. The toggle joint forms an angle in a first angular direction to lock the dog in a load engaging position during engagement of a load under the predetermined magnitude. The toggle joint further shifts to form an angle in a second angular direction upon engagement of a load in excess of the predetermined magnitude, thereby allowing the dog to pivot away from the load which is in excess of the predetermined magnitude.

  • Patent number: 6367612
    Abstract: A retractable pusher dog for an overhead power and free conveyor system is provided. The retractable pusher dog comprises a body portion formed from a rectangular cylinder with a spring and pusher member disposed within the cylinder. When a force greater than the static spring force is applied to the pusher member, the pusher member retracts into the body portion thus reducing the overall height of the pusher dog. Due to its self-actuating retraction, the retractable pusher dog of the subject invention requires no modifications to the powered and free rails or to the load trolleys. The retractable pusher dog will prevent jamming of load trolleys by allowing the pusher dog to bypass an off-timed load carrier, introduced from a different powered rail, until it is properly aligned on the main rail. Also, the body plates of the pusher dog facilitates coupling the pusher dog to the drive chain without disassembling the drive chain thus reducing downtime of the conveyor system and labor costs.
