Methods and apparatus for cleaning a mat are disclosed. The disclosed process receives a user identifier, such as a phone number and/or PIN, at a mat cleaner from a user. The mat cleaner then accepts a mat, such as a yoga mat, form the user and conveys the mat through the mat cleaner. Various guides and sensors are employed to facilitate straight insertion and smooth conveyance of the mat through the mat cleaner. As the mat is conveyed, the mat is illuminated with ultraviolet light and sprayed with a recirculated cleaning solution. The mat cleaner includes a sensor, such as a float switch, to facilitate determination of the circulated cleaning solution level.

A method and a device are provided for replacing individual idler rollers for conveyors, with which a web belt can be lifted and worn-out or damaged idler rollers in upper and lower runs can be individually replaced. The device includes, separately for replacing the idler rollers in the upper run and in the lower run, a subframe (1) for lifting the web belt (7) and for holding the web belt (7), such that a sufficient clearance is formed for replacing worn-out idler rollers (53) by means of a changing frame (2). A service vehicle is equipped with a lifting apparatus for moving dividing devices. The process steps include lifting the web belt (7), removing the old idler roller (53.sup.old), inserting the new idler roller (53.sup.new) and lowering the web belt (7). The drawing shows the use of two dividing devices in the replacing of idler rollers in the upper run.

A transport system (S) comprises a guide path (1) and at least one mobile carriage (2) movable along the guide path (1). The guide path (1) comprises a first guide profile (11) and a second guide profile (12). A single pair of rollers (31, 32) are mounted rotatably in an independent way to one another on a first rotation shaft (51) borne by the mobile carriage (2) so as to be in contact with the first guide profile (11). A first pair of rollers (41, 42) and a second pair of rollers (43, 44) are mounted rotatably in an independent way to one another on a second rotation shaft (52) and on a third rotation shaft (53) borne by the mobile carriage (2) so as to be in contact with the second guide profile (12).

In an aspect, a wear plate for use with a conveyor system is provided. The wear plate has a plate mount, having a fastener retainer having a retention hole extending through the wear plate, and a retainer support being defined by at least one cut in the wear plate adjacent to and at least partially defining the fastener retainer, the retainer support connecting the fastener retainer to a main portion of the wear plate and enabling the fastener support to be depressed relative to a top surface of the wear plate.

A secure roller controller of a roller conveyor system for logistics services includes a monitoring circuit, a controller module and a driving circuit and is electrically connected to a motor. The monitoring circuit is electrically connected to the controller module and the driving circuit to receive a power signal from the driving circuit. The controller module is electrically connected to the driving circuit to receive the power signal and instruct the driving circuit to drive the motor for speed adjustment according to the power signal. When instantly detecting that the power signal is irregular, the monitoring circuit transmits an irregularity signal to the controller module for the controller module to instantly decelerate a rotation speed of the motor to a safe rotation speed through the driving circuit. Accordingly, burn-down of the motor and the secure roller controller can be avoided to enhance operational stability and safety.
