A pivot element (40) is spaced apart from the return roller in the running direction. A pivot bearing (22, 23) is arranged on the articulation region for mounting the pivot element for a pivoting movement of the pivot arm around a pivot axis between an operating position and an nonoperating position of the return roller. A bearing surface (24, 25), in a section perpendicular to the pivot axis, is formed as an open arc, with an opening (26, 27) having a center angle (φ) of less than 180°.

A conveyor belt cleaning assembly includes a first rail member, a second rail member, and a locking mechanism for removably securing the first rail member to the second rail member. The first rail member includes a first base wall, a first leg extending from a first end of the first base wall, a second leg extending from an opposite second end of the first base wall, a first bottom retaining wall, and a first side retaining wall defining a first inner taper portion extending inwardly toward the second leg. The second rail member includes a second base wall, an inner wall, an opposite outer wall, a second bottom retaining wall, and a second side retaining wall defining a second inner taper portion extending inwardly toward the inner wall. The second inner taper portion is a mirror image of the first inner taper portion.

An apparatus/method for a conveyor belt lifter apparatus that can be manually-configured to accommodate differently-sized conveyor belts of conveyor systems. The apparatus includes a pair of lifts in between which a trough-shaped adjustable conveyor belt support arm is releasably-secured. An adjustable shaft coupler connects the lifts to allow simultaneous activation and movement of both lifts by an operator engaging only one lift. An adjustable base also allows the apparatus to be adjusted for the conveyor system size. These adjustable components comprise segments that can be releasably secured using quick-release pins. The height of the ends of the conveyor belt support arm can also be manually adjusted to eliminate any gap between the conveyor belt and the support arm before lift activation. Each lift comprises a manually-controlled screw jack with an extender formed thereon to allow the lifter apparatus to raise or lower the particular conveyor belt once the lifter apparatus is installed.

A load handling device is disclosed for lifting and moving storage containers stacked in a grid framework structure having first and second sets of parallel rails or tracks. The load handling device includes: a body mounted on first and second sets of wheels arranged to engage with the tracks. A direction-change assembly is arranged to raise or lower the first set of wheels and or lower or raise the second set of wheels with respect to the body to engage and disengage the wheels with the tracks. The direction-change assembly includes a linkage-set having a series of members arranged between a traveller and a fixed brace, wherein the traveller is arranged to move under an applied force to cause the wheels to raise or lower.

A drive belt assembly for a load handling device includes a drive belt; a drive wheel; and one or more driven wheels. A first tensioning arm, having a fixed end above an elbow and a rotatable distal end pivotally attached at the elbow, is horizontally displaceable relative to the drive wheel and driven wheels. A second tensioning arm is provided wherein the drive belt is routed around the first and second tensioning arms, and the first and second tensioning arms are arranged to put pressure on the drive belt to tension the drive belt.

A storage system including a storage grid including vertical column profiles defining a plurality of grid columns. The grid columns include storage columns, in which storage containers can be stored one on top of another in vertical stacks. The storage grid including at least one rail grid at the upper ends of the column profiles, and a first container handling vehicle and a second container handling vehicle. The first and the second container handling vehicles each include at least one wheel base unit and a first container handling module or a second container handling module. Each wheel base unit having a wheel arrangement for movement of the wheel base unit in two perpendicular directions upon a rail grid of the storage system. The first container handling module is a different type of container handling module to the second container handling module.

Module (1) for a modular conveyor mat, comprising coupling elements (9) at the front and rear of a body part (4). The coupling elements (9) comprise a series of successive hinge parts (10) and receiving spaces (11), wherein hinge parts (10) and receiving spaces (11) can interdigitate with receiving spaces (11) and hinge parts (10) of a similar module (1) successive in convening direction, and successive modules are hingedly couplable using hinge pins extending transversely to the conveying direction, reaching through hinge bores (13) provided in the hinge parts (10). The body part (4) is provided in the middle with a dividing plane (D) which extends parallel to the sides and along which the module (1) is divisible into two module halves (1A, IB). The pairs of coupling elements (9z) located on the sides are, viewed in the direction of the main axis, implemented with a greater width (B) than neighboring coupling elements of the body part (4). Further, pairs of coupling elements (9d) located on both sides of the dividing plane (D) of the module (1) are also implemented with the same width (B) as the coupling elements (9z) with the greater width (B) located on the sides.

A conveyance device includes a slider, a conveyor including a plurality of conveyance modules to convey the slider, and a connecting member provided separately from the conveyance modules and configured to connect the conveyance modules adjacent to each other such that a signal is transmittable. The conveyance device further includes a first indicator provided so as to correspond to each of the plurality of conveyance modules and configured to indicate states of the conveyance modules.

A storage shelf includes: a main frame; a plurality of shelf modules each having a base plate detachably provided on the main frame, and a supply nozzle provided on the base plate; a main pipe through which purge gas supplied from a supply source flows, and a first branch provided in the main pipe and branches a flow path from the main pipe, in which the shelf modules are each provided with a mass flow controller configured to adjust the flow rate of the purge gas supplied to the supply nozzle, the first branch is connected to a module pipe via an open/close valve that opens/closes the flow path, and the mass flow controller is connected to the module pipe.

A split drive sprocket assembly includes: a first sprocket portion and a second sprocket portion configured to be joined along an opposing mating surface to form a cylindrical sprocket body; a series of teeth extending radially from a circumferential end of the first sprocket portion and the second sprocket portion; a first shoulder connected to the first sprocket portion and extending radially so as to extend from an axial further than the teeth extends from the axial and spaced axially apart from the teeth; a second shoulder connected to the second sprocket portion and extending radially so as to extend from the axial further than the teeth extends from the axial and spaced axially apart from the teeth.
