A roller conveyor device including a three-line conveyor for conveying objects that form at least three lines extending in a conveying direction. The three-line conveyor includes first conveyor rollers for conveying ones of the objects that form at least one central line of the at least three lines, second conveyor rollers for conveying ones of the objects that form at least one non-central line of the at least three lines, and third conveyor rollers for conveying ones of the objects that form another at least one non-central line of the at least three lines. A rotary shaft of each of the first, second and third conveyor rollers includes a shaft end portion having a projection portion that projects out from a conveying path in a widthwise direction of the conveying path, and the projection portion is to be driven so as to convey the objects in the conveying direction.

A support frame for a conveyor system, the support frame comprising: an upright longitudinally extending between an operative lower end and an operative upper end; a cross member extending outwardly from the upright between an upright end and a trolley end, the cross member including a trolley located towards the trolley end of the cross member and which trolley is operatively adapted to suspend the upright from an overhead rail; and an idler assembly attached to the upright and operatively adapted to support a carry belt portion and a return belt portion of a conveyor belt.

A method of recognizing consecutive objects on a conveying path in a detection zone arranged on the conveying path comprises the following steps: generating an electromagnetic radio frequency field radiating into the detection zone by way of a radio frequency sensor; measuring a time curve of a dielectric conductivity in the detection zone by using of the radio frequency field of the radio frequency sensor; and determining contour information of the consecutive objects from the time curve of the dielectric conductivity.

A production method and system performing the production method, the method includes detecting integrity of a hermetic seal of a container that is being transported by a conveyor, the container including an elastically deformable cup containing a product and a fluid, and having an open mouth and a deformable lid attached around the open mouth of the cup, the detecting including squeezing the cup to pressurize the fluid contained in the container; and determining with a detector whether the squeezing caused the lid to deform; and when it is determined that the squeezing failed to deform the lid, removing the container from the conveyor.

A trough-belt conveyor with adjustable bearing support wings and methods for operating the conveyor to sort or destack articles. The conveyor includes a flexible conveyor belt supported in a series of support beds. Adjustable support beds have a base bearing member flanked by a pair of bearing wings. One or both of the wings are adjustable to raise or lower the sides of the belt above and below the plane of the center of the belt supported atop the base member.

Disclosed herein are systems and devices which transport and stack flexible textile workpieces (e.g., clothing) in a processing line. A proposed stacking device includes a conveyor belt wound through a series of rollers which permit horizontal extension of the conveyor path toward a downstream workstation. The extendable conveyor path allows for easy transferring and stacking of the workpieces at the downstream workstation.
