摘要:
A conveying system has access to a first supply means (11) for supplying a plurality of types of first automobile body components (10a) having different shapes, a second supply means (13) for supplying a single type of second automobile body component (12), and conveys the automobile body components in a combined manner to a next processing station. With the conveying system, a fourth lift (16) receives first body components (10a) of a first type and second body components (12) of a single type from a first carrier (18) and delivers them via a second fork lift (23) to a transfer area near the next processing station, or receives the second components (12) via the second fork lift (23) and the first components (10c) of a second type via a third lift (40), and delivers them to the transfer area when only the second component arrives via the second fork lift (23).
摘要:
This invention relates to an overhead work suspension conveyor for conveying a piece of work, for example, a tailgate to a main body in an assembly line of a vehicle main body. An object of this invention is to efficiently and surely hold plural kinds of work pieces of different configurations in a suspended position and to permit their easy loading on a work conveyance mechanism. This invention therefore provides an overhead work suspension conveyor comprising a traverser main body, plural spindles turnably supported relative to the traverser main body, plural work support members fixed at upper ends thereof on the spindles and having work supports at lower ends thereof, said work supports being turnable responsive to turning of the corresponding spindles to support a piece of work at an outer periphery thereof, and a spindle drive mechanism arranged on the traverser main body and adapted to selectively turn the spindle depending on the kind of the work piece.

In order to suppress ammonia from flowing out during regeneration treatment of a filter carrying an SCR catalyst, the prevent invention provides an exhaust emission control system of an internal combustion engine, including a first stage catalyst having an oxidation function, a fuel supply device configured to supply fuel to the first stage catalyst, a filter provided in the exhaust passage downstream of the first stage catalyst and carrying a selective redaction type NOx catalyst, an ammonia supply device configured to supply ammonia to the filter, a filter-regeneration-treatment executing unit configured to execute filter regeneration treatment, and a control unit configured to supply, when the filter regeneration treatment is not executed, the ammonia in an amount corresponding to an amount of the NOx emitted from the internal combustion engine, and to supply, when the filter regeneration treatment is executed, the ammonia in an amount corresponding to an amount of the NOx obtained by subtracting, from the amount of the NOx emitted from the internal combustion engine, an amount of the NOx reduced by the fuel which passes through the first stage catalyst.
摘要:
In an exhaust gas purification system for an internal combustion engine provided with a filter supporting an SCR catalyst, the present invention is intended to suppress HC and CO from being discharged to the outside at the time of the execution of filter regeneration processing, and to carry out the filter regeneration processing in an efficient manner. In the present invention, a post-catalyst having an oxidation function is arranged in an exhaust passage at the downstream side of the filter. Then, when the temperature of the post-catalyst is lower than a predetermined activation temperature at the time the execution of the filter regeneration processing is requested, the temperature of the post-catalyst is raised by carrying out control of raising the temperature of the exhaust gas discharged from the internal combustion engine, and control increasing the flow rate of the exhaust gas, before the execution of the filter regeneration processing.
摘要:
An object of the present invention is to suppress HC, CO, and NOx from being discharged to the outside when a filter regeneration process is executed in an exhaust gas purification system for an internal combustion engine provided with a filter including an SCR catalyst carried thereon. In the present invention, a post-catalyst is provided for an exhaust gas passage disposed on a downstream side from the filter. The post-catalyst has an oxidizing function, and the post-catalyst has such a function that the production of N2 based on the oxidation of ammonia is facilitated in a predetermined first temperature area. Further, when the filter regeneration process is executed, the temperature of the post-catalyst is adjusted to be in the first temperature area while adjusting the temperature of the filter to be in a predetermined second temperature area lower than a filter regeneration temperature during a certain period of time.

The pair of cutting blades are pin joined to each other at their terminal webs which are joined to bow handles. A ball bearing is mounted to the pivot pin by way of an antifriction spacer for providing a permanent spacing between the terminal webs in order to prevent the same from abrasion and consequent uneven wear. A clamp is coupled at one end to the pivot pin projecting from one of the terminal webs, and anchored at another end to the other terminal web, in order to bear the component of cutting resistance which tends to spread the pair of blades in opposite directions away from their parallel planes of motion.

An exhaust gas purification device of an engine comprising a particulate filter arranged in an exhaust passage. An electric motor able to impart a vehicle drive power separate from the engine and able to generate electric power from the engine is provided. After the particulate filter finishes being warmed up, when the temperature of the particulate filter is low, the output torque of the engine is increased and the amount of increase of the output torque is consumed by the power generating action of the electric motor.

An exhaust gas purifier includes a particulate filter for oxidizing collected particulates, a reversing device that reverses an exhaust gas upstream side and an exhaust gas downstream side of the particulate filter. The particulate filter includes a collecting wall for collecting the particulates, which includes a first collecting surface and a second collecting surface. The first and the second collecting surfaces are alternately used for collecting the particulates by the reversing device. The catalyst device is arranged adjacent to the particulate filter at a position always being at the downstream side of the particulate filter.

A pair of vertical guide rails of a workpiece transporting system are comprised of upper and lower rail portions, the upper rail portions being movable into axial alignment with the lower rail portions, the upper and lower rail portions being supported from a ceiling member of a building, and thus movable in unison with each other in the event of movement of the ceiling member of the building. A joint between the upper and lower rail portions of one guide rail is arranged at a vertical height different from that of the joint between the upper and lower rail portions of the other guide rail.

This invention is directed to a method and a device for positioning a body transported on a conveyer as a transporting path at a longitudinal predetermined positioned or a lateral predetermined position on the path. The method positively positions the body at a plurality of positions by way of selectively shifting and holding a longitudinal positioning member or a lateral position restricting plate, which slideably contacts with a vertical projecting wall of the body, at the longitudinal predetermined position depending on the configuration of each body, prior to the arrival of the body at either predetermined position on the path. The device comprises a structure mechanism including longitudinal positioning apparatus which enables selectively shifting and holding the longitudinal position of the body at a plurality of positions in contact with a tip reference portion of the body transported on the conveyor; lateral positioning apparatus which enables selectively shifting and holding the lateral position of the body at a plurality of left and right locations using the lateral position restricting plate slidable in contact with the vertical projecting wall of the body; and control apparatus for supplying a shifting signal to such positioning apparatuses on setting thereof, the control apparatus being implemented so that the body is selectively shifted to and controlled at either predetermined position depending on the configuration of each body.
