摘要:
Method and system (10) for transporting products (2). A conveyor surface (1) is moving at a conveyor velocity (VI). Products (2) are provided on the conveyor surface (1) in a measurement zone (M). The products (2) move through the measurement zone (M) with a product velocity (V2) that is at least initially different than the conveyor velocity (VI). A contact between the products (2) and the relatively moving conveyor surface (1) causes the products (2) to accelerate or decelerate (a) in the measurement zone (M) depending on a kinetic friction coefficient (μk) there between. A control signal (S) is indicative of the acceleration or deceleration (a) of the products (2) in the measurement zone (M). The kinetic friction coefficient (μk) is controlled based on the control signal (S) to keep the acceleration or deceleration (a) within a predetermined threshold range.

摘要:
An automobile factory planning system and method for controlling a cycle time. The system comprises a conveyor belt configured to transport a plurality of automobiles at a controlled displacement velocity along a manufacturing path through the automobile factory. A feedback device is configured to provide a visual indicator of a designated position at which a next automobile is to be placed on the conveyor belt relative to the position of a previous automobile. The designated position is calculated as a function of the cycle time and the displacement velocity of the conveyor belt.
摘要:
A modular conveyor (1) comprising a conveyor mat or chain (2) constructed of a series of links (3) hingedly connected together into an endless loop arranged to be circulated around two spaced diverting wheel units (4, 5). Each link is positioned at a pitch distance from an adjacent link, which pitch distance is at least substantially the same throughout the conveyor mar or chain. At least one of the diverting wheel units (5) comprises a drive shaft (9), a drive wheel (10) mounted on the drive shaft and drivingly engaging the conveyor mat or chain and further an upper idler wheel (12) mounted on an idler wheel shaft. The upper idler wheel shaft is positioned above the drive wheel shaft, such that intermediate distance between said upper idler wheel shaft and drive shaft equals a distance of (n times the pitch distance+substantially a ½ time the pitch distance).

Coupling of conveyor belt modules A module (2) for a modular conveyor chain, comprising a link portion (3) made of sheet metal that includes a substantially elongate conveying body (4), the conveying body having a central hinge loop (5A) on one longitudinal side thereof and a pair of offset hinge loops (5B) on an opposite longitudinal side thereof that are interspaced to receive the central hinge loop of a link portion of a consecutive module therebetween. The central hinge loop and/or or the offset hinge loops are distanced with their free end(s) from a bottom face of the conveying body to form a through pass aperture (16) through which a hinge pin (12) held in the hinge receiving space(s) of the hinge loops of other module may pass transversely to its axis into or out of its hinge receiving space.

A module (1) for a modular conveyor chain (8), comprising a link portion (2) made of sheet metal that includes a substantially elongate conveying body (3), having a centrally located coupling piece (4) on one longitudinal side thereof and a pair of coupling pieces (4) on an opposite longitudinal side thereof, that are inter-spaced to receive the centrally located coupling piece of a link portion of a consecutive module therebetween, wherein the coupling pieces extend from the body part to loop around a receiving space (5) for a hinge pin (7), wherein the coupling pieces form less then a three quarter loop relative to a plane defined by the conveying body.
摘要:
A transfer device (19), comprising a carrier (21) including a number of mutually spaced-apart, substantially parallel extending transfer fingers (22) that in use reach into grooves (14) between ribs (13) on a conveying surface of a grooved conveyor belt (2). Back parts (23) of the fingers form a comb shaped part (24) of a substantially planar slide-over surface (25) of the transfer device. The carrier further includes a conveyor guide track (26) that is lowered with respect to the slide over surface and that extends transversely to the fingers, and that in use is provided with a cross conveyor belt (6) movable in a conveying direction transversely to the fingers, so that a conveying surface (9) of the cross conveyor belt forms a conveying part (27) of the slide-over surface that is substantially contiguous to and flush with the comb shaped part (24). At a side opposite to the fingers the carrier further includes a hinge connection (29) extending transversely to the fingers, and being spaced apart from the fingers. Further, the carrier includes support surfaces that in is use are supported on the grooved conveyor belt.

Module (1) for a modular conveyor mat, comprising a body part (2) extending transversely to a conveying direction with a top (3) and a bottom (4), which bottom is provided with a tooth chamber (6) for receiving a driving tooth of a sprocket wheel. The body part, at a front (7) and rear (8), is provided with a series of hinge parts (9) and receiving spaces (10) alternately successive transversely to the conveying direction, so that successive modules (1) are hingedly couplable using hinge pins (11) extending through hinge bores (13) provided in the hinge parts. The front is part of a front body part (2A) of the module and the rear is part of a rear body part (2B) of the module. The front and rear body parts are hingedly connected with each other relative to a pivoting axis (Z), which traverses the tooth chamber (6).

End drive for a conveyor, comprising a conveying track (6) for, during use, guiding a conveying part of a straight-running modular conveyor mat (2), a return guide (10) extending at a distance along the conveying part for return guidance of a return part of the conveyor mat, and a gear drive (16) located between the conveying track and the return guide for, through engagement of the conveyor mat, drivingly having the conveyor mat round from the conveying track to the return guide. The return guide comprises a guiding envelope (E), linking up with the gear drive and extending along successive rows of modules, in which movement of the return part of the conveyor mat both sideways in the plane of the conveyor mat and transversely to the conveying plane is limited.
摘要:
Modular conveyor chain, comprising a number of successive, mutually hingedly connected modules. The modules each comprise a link portion made of sheet metal that has a body part that forms a conveying surface. The body part is provided with a centrally located coupling piece on one side thereof, and a pair of interspaced coupling pieces on an opposite side thereof that include an interspace in between. The coupling pieces of successive modules cooperate to form a hinge assembly because the centrally located coupling piece of a link portion is received in the interspace between the interspaced coupling pieces of a link portion of a successive module, and because a hinge pin extends through aligned receiving spaces of the cooperating coupling pieces. The modular conveyor chain further includes a plastic bearing element received between the centrally located coupling piece and the hinge pin. The hinge pin has a substantially constant cross section, and a central portion of the hinge pin is provided with a bearing element that has a closed cross section and extends along the hinge pin at the location of the central coupling element only. Opposing ends of the hinge pins are each provided with an end cap that includes a mantle portion that extends along the hinge pin at the location of an interspaced coupling piece only, and a radially inwardly extending flange portion that cooperates with an end face of the hinge pin.
