A dollie assembly for a vehicle wash includes a center link configured for attachment to a drive mechanism of the vehicle wash and having a throughhole with a first bushing extending therethrough along an axis between opposite ends with cylindrical bearing surfaces on opposite sides of the center link. A tire pushing roller is disposed on each of the bearing surfaces for rotation about the axis. A pair of track rollers are supported for rotation about the axis. The track rollers are disposed on an opposite side of the pair of tire pushing rollers from one another such that the pair of tire pushing rollers are between the pair of track rollers. The pair of track rollers are rotatable about the axis independently from pair of tire pushing rollers.

A system comprises a track surface and includes a plurality of motors. The system may further include a plurality of chains. Each chain may be coupled to a motor and may be disposed along a length of the track surface. A plurality of pushers may further be included, with each pusher coupled to a chain of the plurality of chains. In some examples, a controller may be coupled to the plurality of motors.

An automated food grade conveyor, placement and feeder device and system for singulating and placing rolls, egg, meat, or protein patties, and/or cheese and other foodstuffs to assemble and prepare a sandwich, the system being made of food grade materials that are easily cleanable and being made compact and on wheels which results in a system that significantly reduces time, labor, and waste while increasing productivity, quality and freshness; it includes bulk feeding specific food items through a food grade centrifugal feed system, placing the food items with a chain driven pick and place device, transferring food items to separate servo driven trains, automatically placing of a food pattie onto a sliced bun, wrapping of a completed sandwich, and placing the sandwich on a tray, box or container.

Various embodiments of the present disclosure provide a lumber handling and cutting apparatus, including an incoming material conveyor assembly, a material infeed assembly adjacent to the incoming material conveyor assembly, a cutting assembly adjacent to the material infeed assembly, a material outfeed assembly adjacent to the cutting assembly, an outgoing material conveyor assembly adjacent to the cutting assembly, and a printer assembly adjacent to the incoming material conveyor assembly and the material infeed assembly.

A wheel roller for a chain conveyor of an automated carwash has a more robust configuration due to a direction connection of the wheels to the carrier link. The wheel roller contains a carrier link forging having a main body with a carrier link formed as an unitary component, pins secured to the main body in a fixed, non-pivotable manner, and wheels attached to the pins.

A support portion includes: a first portion that is supported on a travel portion; a second portion that is coupled to a holding portion; and a damper portion that is provided between the first portion and the second portion. The damper portion includes: a guide portion that guides movement of the first portion relative to the second portion along a specific guiding direction; a link mechanism that is coupled to each of the first portion and the second portion, and that moves in conjunction with movement of the first portion relative to the second portion; and an elastic body. The elastic body is coupled to the link mechanism so as to dampen operation of the link mechanism.

A conveying device includes a conveyor and a carrying member. The conveyor is movable along a transporting path that sequentially defines an upstream segment and a downstream segment, and an outer surface of the conveyor includes a detecting region. The carrying member is mounted on the outer surface of the conveyor. A height of the carrying member with respect to the outer surface is larger than or equal to 3 mm.
