A reel motor (1) for a driven conveyor roller has a stator (11) that is surrounded by a stator housing (10). A rotor (12) drives a rotor shaft (13). A tubular external housing (30) runs around the stator housing (10) at a distance in the circumferential direction. A cooling duct (20) is fluidically connected to an interior of the stator housing (10) holding the stator (11). The cooling duct 20 is formed between the external housing (30) and the stator housing (10). An impeller wheel (14) is secured to the rotor shaft (13). The impeller wheel generates a cooling air flow (K). The interior of the stator housing (10) and the cooling duct (20) determine a closed cooling circuit. The cooling air flow is guided through the closed cooling circuit.

The present disclosure illustrates an inspection apparatus for a display panel and a testing method for display panel. The inspection apparatus includes a platform, a feeding device, a rotatable bearing stage, an optical panel inspection device, a discharging device, a rotation driving device and a transfer device. The platform includes a support frame having a loading-and-unloading area and an inspection area. The feeding device transports the display panel along a feeding direction. The rotation driving device includes a rotation axe and a rotation driving mechanism. The rotation axe has an end fixed at a central part of a bottom surface of the rotatable bearing stage, and the rotation driving mechanism can rotate the rotation axe. The display panel placed on the rotatable bearing stage can be exchanged between the loading-and-unloading area and the inspection area when the rotatable bearing stage is rotated.

A link for a conveyor chain includes a first portion and a second portion laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin, and the second portion includes a second sprocket-engaging pin. The first sprocket-engaging pin and the second sprocket-engaging pin protrude laterally away from one another. The first sprocket-engaging pin and the second sprocket-engaging pin may each have an oblong cross-section. At least one retainer can secure a connecting pin against movement relative to at least one of the first portion and the second portion, and each retainer can be positioned substantially within one of the first portion and the second portion.

A conveyor roller includes a roller tube, a motor assembly comprising a motor and a motor shaft and a drive assembly engaged with the motor assembly and the roller tube. The drive assembly includes a drive member, a connector, and a sleeve. The drive member includes at least one first slot that axially extends from a front face of the drive member towards a rear face. The connector includes an axial opening and at least one first projection extending radially outwardly. A sleeve disposed at least partially between the connector and the drive member. The sleeve is configured to engage the at least one first slot of the drive member and the at least one first projection of the connector. A portion of the sleeve extends radially outwardly of the drive member, such that the portion of the sleeve is configured to engage an inner surface of the roller tube.

A control device (1) for a goods transport conveyor (100) has a processor (10) that generates control signals for at least one drive motor (350) of a transport section (110; 120; 130) of the goods transport conveyor (100). The motor operates in stop-and-go mode. The processor (10) is configured to control the drive motor (350) by means of a forward phase and/or reverse phase when the transport section (110; 120; 130) of the goods transport conveyor (100) stops such that the torque (M(t)) produced by the drive motor (350) is reduced according to an adjustable stopping function. The processor (10) sets the stopping function depending on detected process data of the transport section (110; 120; 130).

The present invention includes conveying and sorting systems utilizing a plurality of continuous rails which support a plurality of sliding pucks that are urged forward using a plurality of sprocket wheels, and which utilize magnetically operated activation components for causing produce to be selectively dropped from cups carried by the pucks into sorting bins. The structures for the conveying and actuating components of the systems have smooth external surfaces reducing potential contamination by bacteria, contaminants and debris, thereby making them easily accessible for cleaning, and allowing for longer continuous operation times and higher efficiency.

A method for state monitoring in a conveyor system, and also to a control unit, to a motorized roller, to a conveyor zone, to a conveyor section and to a conveyor system for carrying out this method. The method comprises checking for the presence of a reference operating state, determining a current of the motorized roller if the reference operating state is present, and comparing the determined current of the motorized roller with a reference value for the reference operating state.
