Implementación de una máquina con control automático de temperatura para la reactivación del adhesivo para plantas de calzado.

Abstract

A reactivator with temperature control was designed and implemented to glue the adhesive in footwear plants based on robust automation elements, with a man machine interface made on a touch screen where the control is carried out. This prototype was carried out in several phases, the first one being the adjustments and design of the grill-type reactivation oven that performs electric heating with the ability to reactivate three pairs of soles at the same time. In a second phase, the devices used according to the design made by software were established, trying to reduce costs so that the machine is accessible to artisans. Without diminishing the technology in relation to the existing machinery in the market that is totally of import and of high cost. The elimination of the risk of using an oven that works with liquefied petroleum gas (LPG) was also determined. In addition, the TP 100 sensor was determined as appropriate according to its characteristics and the implementation of the control panel and power was performed by calculating the cable sizes and circuit protections. The programmable logic controller (PLC) inserted performs temperature control according to the type of material of the plants, generating a single productive process for the final phase of the bonding of the plant, which in the footwear industry increases the quality of production without increasing operating costs. It was determined that the cost of manufacturing the reactivator is reduced by more than 100% in relation to its counterparts without decreasing in technology and in many cases even higher; In addition, the operating cost in relation to gas furnaces does not change, while decreasing production times by 40%, it generates security and creates a manufacturing process, which is established as standard and normalizes the production of footwear.
