Abstract

As in any industry, in soft drink manufacturing demand, customer service and production are of great importance, which forces this production to have its equipment and production machinery in optimal conditions so that the product is in the hands of the consumer without delays. Therefore, it is important to have the established times for each process, from when the syrup is made, packaged, distributed, until it is purchased by the consumer.

After a stopwatch analysis, the most common failures in each analyzed process are known. In the filling machine, the most frequent failures are: accumulation of bottles in the processes before and after the filling machine, which is usually caused by failures in the other equipment in the production line. In the unloading process, the most common failures are: boxes stuck in the tipping stop and in the box pusher; boxes fallen on rollers and pallet conveyor. According to what was observed in each machine, the actions to be followed are proposed to solve the problems that arise.

The description of the methodology that is followed to obtain results, analyze them and make decisions is presented. First, an analysis of operations is made to know each machine, supported by the machine manuals and the operators themselves, a study of times with a stopwatch is carried out to determine the standard time of the process, where the most common failures are also presented, then observations are made in the machines according to the determined sample size, thus obtaining the necessary information to take measures and carry out the optimization study of the production processes. An analysis of the predetermined times of the process is also carried out using the MTM and MOST time analysis methods.

The results of operators with MTM are:

Filler with failures = 0.846 minutes, Filler without failures =

0.61 minutes, Unstacker with failures = 0.74 minutes and

Unstacker without failures = 0.45 minutes.

The results of operators with MOST are:

Filler with failures = 2.58 minutes, Filler without failures =

2.35 minutes, Unstacker with failures = 2.15 minutes, Unstacker without failures = 1.68 minutes.

It is concluded that time analysis is an adequate tool

to determine the time of the processes and make recommendations for improvement, to minimize or avoid lost time and optimize the operating conditions in the process.
