Provided is a drip-proof device for a passenger conveyer, which is capable of improving working efficiency of maintenance work performed in a machine room. The drip-proof device for a passenger conveyor includes gutters, which are provided to a floor plate for opening and closing an opening portion of a machine room, and are each configured to receive water passing through a gap between wall surfaces of the opening portion and the floor plate, and a gutter displacement device configured to displace the gutters. Each of the gutters is displaced between a water-receiving position for receiving the water passing through the gap and a receiving position for allowing removal of the floor plate through the opening portion. The gutter displacement device includes a rotary member configured to rotate through an operation of the rotary member- and rods configured to displace the gutters through the rotation of the rotary member.

A trolley assembly for overhead track testing is provided. In one example embodiment, a trolley assembly includes an idle roller that rotates about a first axis, a first top roller coupled to a first end of the idle roller via a first trolley upright support, and a second top roller coupled to a second end of the idle roller via a second trolley upright support. The trolley assembly includes a cantilever coupled to the idle roller. The trolley assembly includes a driveshaft coupled to a first end of the cantilever. The trolley assembly includes at least one motor coupled to the drive shaft.

An apparatus having an automatically adjustable pot seedling feed rate and a method therefor are provided. In some embodiments, the apparatus comprises a pot seedling scooper, a conveyance unit, a detection sensor, a controller, a seedling sorting unit, side panels, and brackets. The conveyance unit comprises a servomotor, a transmission shaft, a conveyor belt, a tension shaft, and a bearing. The seedling sorting unit comprises a seedling sorting rod, a reset spring, a guide post and a support seat.

Disclosed is a chain disk corner. In certain embodiments, the chain disk corner includes a bi-directional orientation independent chain disk corner wheel. In particular, the wheel is molded and devoid of moving parts. In certain embodiments, the chain disk corner includes a window portion. In particular, a bottom housing subassembly includes a bottom body of an opaque material and a hingedly attached window portion. In certain embodiments, the chain disk corner includes a reinforcing washer. In particular, a top washer is attached by injection molding to an interior of the top body, and/or a bottom washer is attached by injection molding to an interior of the bottom body. In certain embodiments, the chain disk corner includes a top surface devoid of pockets. In particular, a top body includes a plurality of ribs positioned at an interior surface of the top body.

A continuous conveyor such as, for example, a conveyor belt for transporting heavy bulk materials or unit loads comprises an endless tractive transport mechanism that revolves between a driving roller and a return roller. The driving roller is driven by a permanently excited multi-pole synchronous motor that delivers a very high torque at a comparatively slow nominal speed. The synchronous motor can drive the driving roller directly or alternatively via a single-stage step-down gear with low reduction factor. The drive is characterized by a mass moment of inertia that is up to 10-times lower than in conventional drive systems. In this way, the risk of damaging or even tearing the belt during disruptions is substantially reduced such that the operational reliability significantly increases.

A tensioning system for a conveyor element of a conveyor is provided. The tensioning system includes an obstruction. A base is movable relative to the obstruction. The tensioning system further includes a plurality of spacers. At least one spacer of the plurality of spacers is movable from a resting position to an engagement position by only the influence of gravity. The at least one spacer rests on the obstruction in the resting position. The at least one spacer is disposed between the base and the obstruction in the engagement position.

A friction-type drive apparatus and a carousel comprising the same are disclosed. A friction-type drive apparatus, according to one embodiment, comprises: a motor; a drive pulley rotated by the motor; a belt connected to the drive pulley; a driven pulley rotating in accordance with the drive of the belt; a pressing unit contacting the inner surface of the belt; and an elastic unit for pressing the pressing unit toward the belt.

According to the present disclosure, a conveyor apparatus includes a conveyor frame, a belt provided on the conveyor frame, a motor configured to drive the belt, and a control device configured to control the motor. The control device includes a servo control device configured to control the motor based on a command from a controller, and an inverter control device configured to control the speed of the motor based on an input signal from a speed variable volume.

A transfer device for introducing and/or removing articles to a process device includes a basic frame and a conveying unit, which is supported by the basic frame and transfers or receives articles to or from the process device. The conveying unit is designed to be movably positionable in order for the transfer device to be reversibly advanced up to the process device. The conveying unit includes an output element of a magnetic coupling and is designed for reversibly coupling the transfer device to a corresponding drive element of the magnetic coupling, the drive element being provided on the process device. When the drive element and the output element are coupled to one another, the magnetic coupling effectuates a force transmission from a drive unit of the process device to the conveying unit.
