(54) ВЕСОВОЙ ДОЗАТОР(54) WEIGHT DISPENSER

Изобретение относитс к весо дозирующей технике и может быть использовано в автоматических весовых дозаторах и весах непрерывного действи .The invention relates to a weight dosing technique and can be used in automatic weigh dispensers and continuous weights.

Известны весовые дозаторы дл кусковых материалов, содержащие питающее устройство, весовой транспортер , выполненный в виде рамы, с установленными на ней приводным и концевым барабанами, транспортерной лентой , приводом, одним концом шарнирно опирающимс на фундамент и другим на силойзмерительный датчик 13.Weight dispensers for lump materials are known, which contain a feeding device, a weighing conveyor, made in the form of a frame, with drive and end drums mounted on it, a conveyor belt, a drive, one end hinged on a foundation and the other on a force measuring sensor 13.

Однако в таких весовых дозаторах при дозировании кусковых и особенно крупнокусковых материалов при падении материала с питающего устройства на транспортер в зоне расположени силоизмерительного датчика возникает динамическое возмущение весовой системы, что приводит к снижению эксплуатационной надежности и точности дозировани .However, in such weighing dosing units, when dosing lumpy and especially lumpy materials, when the material falls from the feeding device onto the conveyor, dynamic disturbance of the weighing system occurs in the area of the load sensor, which leads to a decrease in operational reliability and dosing accuracy.

Известен весовой дозатор, содержащий весовой транспортер, выполненный в виде рамы с установленными на ней приводным и концевым барабанами и весовые рычаги123.A weight metering device is known that contains a weight conveyor, made in the form of a frame with drive and end drums mounted on it and weight levers123.

Однако известный весовой дозатор имеет невысокую точность дозировани .However, the known weight metering device has a low metering accuracy.

Целью изобретени вл етс увеличение точности дозировани и упрощение конструкции.The aim of the invention is to increase the metering accuracy and simplify the design.

Поставленна цель достигаетс тем, что оси приводного и концевого барабанов совмещены с ос ми весовых ры10 чагов .The goal is achieved by the fact that the axes of the drive and end drums are combined with the axes of the weight levers.

На фиг. 1 изображен весовой дозатор , вид с бок:у; на фиг. 2 - то же вид |сверху ; на фиг.З - разрез А-Л на фиг.2; на фиг.4 - разрез Б-Б на 15 фиг.1.FIG. 1 shows a weight batcher, side view: y; in fig. 2 - the same view from above; on fig.Z - section A-L in figure 2; figure 4 - section bb on 15 figure 1.

Бесовой дозатор состоит из питающего устройства 1, рычага 2, шарнирно закрепленного на оси 3 приводного барабана 4, установленной на опорных Beso dispenser consists of a power supply device 1, a lever 2, hinged on the axis 3 of the drive drum 4, mounted on the support

Claims

20 bearings 5 mounted on a foundation 6, a lever 7 hinged on an axis 8 of an end drum 9 mounted on support bearings 10 mounted on a foundation 11 of a conveyor belt 12 tensioned on a driving drum 4 and end drum 9 and supported by roller 13, 13 w in levers 2 and 7, connected by a jumper 14, supported by a strain gauge 15, a drive of a conveyor 16 connected to a water drum 4, a chain transmission 17, a setpoint 18, a performance regulator 19, a measurement system 20. The weight metering device operates as follows. The material to be dosed descends from the PI {telling device 1 onto the belt 12 and moves at a constant speed in the direction of the driving drum 4 on a stable weight area L, limited by the point of departure from the feeder and the axis of the driving drum, and is reset for him. The electrical signal of the strain gauge 15, proportional to the mass of the material on the belt 12, is fed to the controller and compared with the signal of the setting device 18. The absence of the difference of signals indicates that the dispenser works with a given capacity, defined as the product of the constant speed of the tracer's belt speed by the instantaneous mass of material on the tape and there is no need to affect the performance of the power supply device 1. When a disturbance occurs, t . when a material dispenser with different parameters (other humidity, volume weight, lumpiness, etc.) comes from the power supply device to the metering tape from the load cell 15, the regulator 19 transmits a signal different from the setpoint 18 signal. The difference of these signals affects the supply device in order to change its performance in the direction of decreasing increase. When the load cell signal 15 is less than the signal of the setting unit 18, the performance of the power supply device 1 is increased in order to achieve a given capacity by the metering device. When the signal of the load cell 15 is larger than the signal of the setting unit 18, the performance of the power supply device 1 is reduced in order to achieve a predetermined performance by the metering unit. The use of the proposed weight metering device allows to increase the metering accuracy. Claims The weight metering device containing a weight conveyor made in the form of a frame with drive and end drums mounted on it, weight levers, characterized in that, in order to increase metering accuracy and simplify the design, the drive and end drum axes are aligned with the axles of the weight levers .
