A feed device for a conveyor system for preforms which transports the preforms coming in an ordered manner from an upstream module of the conveyor system to a downstream module of the conveyor system in which the preforms are separated into singles, wherein the feed device has at least two oppositely arranged transport rails, on which the preforms rest in each case with a support ring. The feed device additionally includes at least two oppositely arranged belt transport units which preferably engage with a threaded portion of the preforms and transport them in a transport direction to the downstream module of the conveyor system, wherein the belt transport units each have a drive which applies a torque to the preforms accumulated in front of the downstream module, which torque the individual preforms are able to be transferred in a more reliable manner from the feed device into the downstream module.

A conveyor belt drive system comprises an axial flux motor. The axial flux motor comprises a stator and rotor bearing mounted on a stationary shaft. The stator drives a toothed rotor mounted on the rotor bearing. The rotor has a tubular shaft extension that mates with a drive shaft that can accommodate standard sprockets. Rotation of the rotor causes rotation of the drive shaft and sprockets to drive a conveyor belt.

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 time the pitch distance).

A linear fixed shaft drive assembly for use in a self-stacking industrial/commercial-grade spiral/gyro oven or freezer that includes a fixed, non-rotatable shaft having a cylindrical mounting portion, a bearing cup supported by the mounting portion, and a hub and shaft base that includes a shaft portion and flange portion. The flange portion is configured to couple to a first side of a flange extending from the bearing cup. A sprocket is mounted to an opposite second side of the flange extending from the bearing cup. The sprocket includes teeth configured to engage with a ball chain assembly of the oven or freezer. The bearing cup includes at least two permanently lubricated bearings. Rotation of the shaft portion of the hub and shaft base causes the bearing cup and sprocket to rotate on the mounting portion of the fixed, non-rotatable shaft. Also a method for retrofitting an oven or freezer having an existing shaft assembly mounted within a thermal chamber of the oven or freezer, and a method for servicing an oven or freezer having an existing linear fixed shaft drive assembly.

Described is a checkout station with an adjustable height conveyor belt, and a motorized height adjustor that is used to level and adjust the height of the conveyor belt. The motorized height adjustor includes an adjustable height leg and a motor drive. The motor drive uses a motor to rotate a foot sleeve of the adjustable height leg. Rotating the foot sleeve adjusts the height of the adjustable height leg. Adjusting the height of the adjustable height leg adjusts the height of the conveyor belt of the checkout station. The motorized height adjustor can be coupled to sensors to automatically adjust the height of the conveyor belt.

A boom assembly for conveying material includes a main boom assembly and a distal boom section. The main boom assembly is mounted at one end, and at the distal end of the main boom assembly there is a distal boom section. The main boom assembly can be a telescoping boom assembly having a fixed section and the telescoping section that extends from and retracts into the fixed section. A main conveyor belt transits the main boom assembly and drives a pulley at the distal end of the main boom section, which in turn is used to drive the distal boom section, in particular the distal section conveyor belt. Other equipment can also be powered using electrical or hydraulic means.

A driver includes: a first motor located so as to rotate a driving shaft; a second motor located so as to rotate the driving shaft; and circuitry. The circuitry performs control while switching between a dual mode and a single mode. In the dual mode, the circuitry drives the first motor and the second motor together. In the single mode, the circuitry drives a drive target motor that is one of the first motor and the second motor and performs such control as to set one or more among a rotational speed, rotation acceleration, and rotation deceleration of the drive target motor to be lower than that or those in the dual mode.

The disclosure relates to a product conveying device for food products, comprising a product conveyor unit which is designed to receive at least one food product on a receiving section thereof and to convey it substantially along a conveying direction from a product receiving side of the product conveying device to a product discharge side of the product conveying device, and a drive unit having a drive element rotatable about a drive axis. The drive element is operatively connected to a driven element of the product conveying unit and is arranged to drive the driven element in rotation about a driven axis thereof in order to move the receiving section of the product conveyor unit in or against the conveying direction, wherein the drive axis of the drive element is substantially parallel, preferably coaxial, to the driven axis of the driven element.
