Problems solved by technology

The existing failure rate calculation method ignores the parallel equipment process, the number of equipment in parallel is different, and the impact on the entire production line is different when the equipment fails. It has certain limitations and cannot truly reflect the actual operating status of the production line.

Embodiment Construction

[0027] Such as figure 1 As shown, in this embodiment, the schematic diagram of the process of the automated production line is as follows figure 2 As shown, the automated production line includes three processes a, b, and c, and process a includes a 1 One piece of equipment; process b is a parallel equipment process, including b 1 , b 2 , b 3 , b 4 and b 5 Five parallel equipment; process c is a serial equipment process, including c 1 and c 2 Two devices in series; device a 1 , equipment b 1 , b 2 , b 3 , b 4 and b 5 , equipment c 1 and c 2 downtime of image 3 shown;

[0028] The calculation method of automatic production line equipment failure shutdown rate includes the following steps:

[0029] Step 1: Obtain the failure weight ω of i equipment in the process of parallel equipment with n equipment connected in parallel i ;

[0030] ω i Indicates the influence degree of i equipment failure on the process of parallel equipment, 0≤i≤n, and i is an integer;...

Abstract

The invention discloses a method for calculating the failure downtime rate of equipment in an automated production line. Firstly, the failure weight ω of equipment i is obtained in the process of parallel equipment connecting n equipment in parallel. i ; via ω i Characterize the influence degree of the number of faulty equipment on its workload in the parallel equipment process, and then calculate the weighted fault downtime rate η of the parallel equipment process and the fault downtime rate η of the automated production line total ;Considering the influencing factors of the different number of equipment failures in the process of parallel equipment, the impact on the production capacity of the automated production line is also different, which more truly reflects the actual operation status of the automated production line.

Description

technical field [0001] The present invention relates to the technical field of failure rate calculation methods, in particular to a calculation method for automatic production line equipment failure downtime rates. Background technique [0002] At present, in order to understand the operation status of equipment, equipment managers need to count statistical data related to equipment operation, such as equipment failure downtime rate, to provide data support for better equipment preventive maintenance and spare parts planning. The traditional equipment failure statistical formula yes: [0003] Fault downtime rate = time when the machine is down due to failure / when the equipment should start the main machine × 100% [0004] This statistical method is only suitable for stand-alone equipment. In an automated production line, it is generally a complex production line composed of multiple processes connected back and forth. Some processes are connected back and forth by one d...
