Various shuttle conveyor designs are disclosed. The conveyors are suitable for conveying objects along a transport direction. The shuttle conveyors may include a track extending along a conveying path, the track defining a length, and a plurality of shuttle elements independently movable along the track. Each shuttle element may define mating structure for following the track along the conveying path. Each shuttle element may include at least one movable gripping member for selectively gripping conveyed objects. The shuttle elements may define a collective length less than the length of the track. A drive mechanism moves the shuttle elements along the track. The shuttle elements may include a plurality of links. The shuttle elements may be driven faster on at least a portion of a return portion of the track than on the conveying portion of the track, and the shuttle element flow along the track may be modulated in various ways.

Shuttle conveyor

A conveyor belt for transporting objects is provided. The conveyor belt includes a plurality of body members. Also included in the conveyor belt are a plurality of surface platform members that are disposed at one side of the body members. An outside surface of the surface platform member is sloped from a first location of higher elevation to a second location of lower elevation. A rail member is located on the surface platform member and is proximate to the second point of lower elevation. The surface platform member is adapted to support an object that is transported by the conveyor belt.

An apparatus for controlling the flow of articles includes a first article moving device and second article moving device spaced apart from the first device to define a space therebetween. A movable transport member is disposed across and movable along the space. The transport member includes a rotatable member drivingly engaged by the first and second article moving devices so as to rotate as either of the devices moves. The transport member travels along the space if a relative speed difference exists between the devices. An article transfer member is carried by the transport member and is disposed between the article moving devices to transfer articles between the devices as the rotatable member rotates.

Apparatus for controlling the flow of articles

A movable transport member used in an article conveying system is disposed across and movable along a space between oppositely running conveyors. The transport member has a drive member that continuously rotates as either conveyor moves. An article transfer member carried by the transport member includes an endless drive belt disposed along a transfer path so as to contact and move articles therealong. The article transfer member further comprises a driven rotatable member having an article contacting surface, the transfer path defined between the drive belt and a circumferential portion of the driven rotatable member.

Article guide for an apparatus for controlling the flow of articles

Sloped surface conveyor belt

An article transfer member including a resiliently mounted guide for aligning articles being transferred onto an outfeed conveyor from an infeed conveyor. The resiliently mounted guide includes an arcuate guide plate that is spring biased so as to flex responsive to variations in the dimensions of the packages being transferred normally as a result of a damaged package and maintaining the packages in alignment on the outfeed conveyor.

An apparatus for controlling the flow of articles includes an infeed conveyor and an outfeed conveyor spaced apart from the infeed conveyor to define a space therebetween. A movable transport member is disposed across and movable along the space. Transport member includes a rotatable member drivingly engaged by the infeed and outfeed conveyors so as to rotate as either of the infeed and outfeed conveyors move. The transport member travels along the space if a relative speed difference exists between the infeed and outfeed conveyors. An article transfer member is carried by the transport member and is disposed between the infeed and outfeed conveyors to transfer articles between the conveyors as the rotatable member rotates.

An apparatus for controlling the flow of articles between a first conveyor driven in a first direction and a second conveyor driven in a second direction includes a movable transport member disposed across and movable along a space between the conveyors. The transport member includes a drive member drivingly engaged simultaneously by the first and second conveyors so as to rotate if either of the conveyors is moving and to travel linearly along the space between the conveyors if a relative speed difference exists between the conveyors. The transport member includes an article transfer device or member disposed so as to contact and transfer articles from the first conveyor to the second conveyor along a transfer path. The article transfer member includes an endless drive belt disposed along the transfer path so as to contact and move the articles therealong. The drive belt runs in an endless path between the drive member and the article transfer member and is drivingly engaged by a belt drive wheel that is driven by the drive member.

This invention provides integrated knuckle drive link conveyor belt systems with improved long wear-high load bearing link coupling joints of a universal joint nature for permitting the belts to travel on straight or curvaceous paths which also feature expedited insertion of spindle rods extending through the knuckles, diverse sprocket drive capabilities and replaceable load conveying platform accessories of the plug-in or snap-in variety. A cylindrical knuckle, when the loaded belt is under tension, has a substantially semi-cylindrical high wear contact surface that handles heavy peak loads. That knuckle is installed expeditiously at a joint between end-to-end connected links constituting a special interfitted jig comprising a seat in the nose end of a link resting the knuckle in a registered operational position to receive the connecting spindle rod through trailing edge bifurcated arms of a leading modular link without a concurrent manual orientation of the knuckle. Diverse sprocket drive structure permits the belt to be driven from beneath or on either lateral side. The knuckle and surrounding seat provides three dimensional moving tolerances to provide the universal joint type operation at each link joint. Other features include side rollers to reduce friction on inner curve radii, and hold down flanges that keep the belt from fluttering off a base support surface. The rugged molded resulting plastic links are long wearing and resist catastrophic failure. The versatility and ruggedness of the system is significantly enhanced by the removable platform structure for heavy industrial use.

Knuckle drive link conveyor belt systems with removable load conveying surface members

An apparatus for controlling the flow of articles from an upstream delivery station to a downstream receiving station and for temporarily storing the articles on a pair of parallel conveyors with a substantial run of the conveyors being in a vertically extending spiral made up of an incoming conveyor and an outgoing conveyor. A movable transport member is used for transferring the articles from the incoming conveyor and the outgoing conveyor at a rate dependent upon the relative speed of the two conveyors.
