Embodiment:
The safety method of last knuckle temperature booster is increased in the bottle placer last knuckle unit that the present embodiment is commonly used at home.This technical scheme efficiently solves and causes because compressed air pressure reduces the phenomenon that last knuckle temperature booster burns due to during last knuckle temperature booster work.Have that reliability is high, structure is simple, economical and practical, reduce the break down maintenance time, improve the advantages such as operation rate.
The present embodiment increases by a pressure switch in the loop of the last knuckle unit of bottle placer, efficiently solves bottle placer and cause owing to being reduced by last knuckle temperature booster compressed air pressure the phenomenon that last knuckle temperature booster burns when intensification, production, maintenance.
As shown in Figure 5, be the improved control circuit figure of last knuckle unit in the bottle placer of the present embodiment.As shown in Figure 6, be the improved control pneumatic diagram of last knuckle unit in the bottle placer of the present embodiment.In bottle placer temperature-rise period, when performing to drift angle, base angle heating step: pressure is that 100 kPas ~ 200 kPas pressurized airs all arrive electromagnetic valve place through the first pressure regulating valve T4200, the second electromagnetic valve T4210, the 3rd electromagnetic valve T4220 and the 4th electromagnetic valve T4230.First electromagnetic valve Y4200, the second electromagnetic valve Y4210, the 3rd electromagnetic valve Y4220 and the 4th electromagnetic valve Y4230 power-off release; Pressurized air arrives last knuckle temperature booster by the first electromagnetic valve Y4200, the second electromagnetic valve Y4210, the 3rd electromagnetic valve Y4220 and the 4th electromagnetic valve Y4230.Simultaneously first often open pressure switch P-AIR211, second and often open pressure switch P-AIR210, the 3rd and often open pressure switch P-AIR209 and the 4th and often open pressure switch P-AIR208 and close because compressed air pressure increases it; Now, if according to the operating temperature of the last knuckle temperature booster reality that temperature controller detects, PLC exports a 24V DC voltage, the path often opening pressure switch conducting after closed powers to the first solid-state relay K211, the second solid-state relay K209, the 3rd solid-state relay K208 and the 4th solid-state relay K207, and relay just gives knuckle heating installation power supply heated compressed air and operation.In the present embodiment, the first knuckle temperature booster R5307 and the second knuckle temperature booster R5308 carries out drift angle heating to the packing of product, and the 3rd knuckle temperature booster R5309 and the 4th knuckle temperature booster R5310 carries out base angle heating to the packing of product.In the present embodiment, electromagnetic valve is for adjusting compressed-air actuated direction, flow and speed.
In bottle placer production process, drift angle, base angle actual work temperature is detected by temperature sensor, and pass to PLC, PLC detects temperature according to temperature sensor, interrupted output 24V DC voltage gives the first solid-state relay K211, the second solid-state relay K209, the 3rd solid-state relay K208 and the 4th solid-state relay K207, solid-state relay controls the operation of last knuckle temperature booster, thus reaches control drift angle, base angle actual work temperature in setting range.Now as arrived the first knuckle temperature booster R5307, second knuckle temperature booster R5308, the compressed air pressure of the 3rd knuckle temperature booster R5309 and the 4th knuckle temperature booster R5310 diminishes, first often opens pressure switch P-AIR211, second often opens pressure switch P-AIR210, 3rd often opens pressure switch P-AIR209 and the 4th often opens pressure switch P-AIR208 and all changes into off-state because compressed-air actuated pressure diminishes by closure state, now, the path Yin Changkai pressure switch of powering for solid-state relay disconnects and is in off state, control the control terminal 3 of the first solid-state relay K211 of last knuckle temperature booster work, the control terminal 3 of the second solid-state relay K209, the control terminal 3 of the 3rd solid-state relay K208 and control terminal 3 pin of the 4th solid-state relay K207 lose the 24V DC voltage of PLC output and cannot work, first knuckle temperature booster R5307, second knuckle temperature booster R5308, 3rd knuckle temperature booster R5309 and the 4th knuckle temperature booster R5310 stops heating because of come out of action voltage, reach last knuckle temperature booster when compressed air pressure diminishes without the order ground that operating voltage is connected.Thus, avoid because compressed air pressure reduces and cause the phenomenon that last knuckle temperature booster burns.
In sum, often pressure switch is opened because in the end knuckle temperature booster pneumatic circuit is set up, when compressed air pressure diminishes or pressure is zero, often open pressure switch and be in off-state, the solid-state relay controlling the work of last knuckle temperature booster accesses without control signal, and therefore last knuckle temperature booster can not be energized.When stopping because being diminished by last knuckle temperature booster compressed air pressure or be zero time, cause last knuckle temperature booster to burn the generation of phenomenon instantaneously.Protect last knuckle temperature booster, add the service life of spare part, improve the running efficiency of equipment.
Above-described specific embodiment party journey; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the invention equation; the protection domain be not intended to limit the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
