锯材指接自动涂胶设备的研制与应用

针对锯材指接涂胶过程中存在的涂胶不均、效率低、涂胶辊易磨损等问题,提出一种锯材指接自动涂胶的方法。基于PLC(programmable logic controller,可编程逻辑控制器),采用自动化检测技术,经过模块化设计,设计了一种新型自动涂胶设备,并进行了锯材指接自动涂胶试验。工厂化试验结果表明:自动涂料设备以200根/30 min的速度工作时,自动1次循环涂胶的合格率可达到97%及以上,且随时间逐渐提高,整个过程中设备无故障;自动2次循环涂胶时,在60—90 min、90—120 min内设备各出现1次故障,合格率均达95%及以上,无故障工作时间内自动2次循环涂胶的合格率可达到98%及以上,而人工涂胶合格率在90%以下。试验表明该自动涂胶设备能够实现快速自动涂胶,保证锯材指接涂胶质量,提高锯材指接涂胶的自动化程度,适合应用于锯材指接的工业化生产。

Development and application of automatic gluing equipment for finger-joint lumber

There are many problems in traditional methods of finger-joint lumber gluing, such as uneven glue, inefficiency and the friction damage of glue roller. In order to solve the problem, an automatic gluing method was proposed. Based on PLC (programmable logic controller), adopting automatic detection technology and modular design, a new automatic gluing equipment for finger-joint lumber was developed. The automatic gluing test for finger-joint lumber was carried out, and the factory test results showed that the gluing qualified rate of the automatic one-cycle gluing with the speed of 200/30 min could reach over 97%, and increase gradually with time, and the equipment had no failure. When using automatic two- cycles gluing, the qualified rate could reach over 95%, and the equipment had one failure respectivly in 60-90 min and 90-120 min. The qualified rate during the trouble-free working time could reach over 98%, while the qualified rate of manual gluing was below 90%. The test shows that the equipment can realize quick automatic gluing, ensure the quality of finger-joint lumber gluing, improve the automation degree of finger-joint lumber gluing, which is suitable for industrial production of finger-joint lumber.
