Abstract
Air brake classifying apparatus for the impurities in the fiber flow. The fiber compacts a baffle plate and blown out in a reverse direction of the fine-fiber by the air nozzle therein.
Description
Technical field
About detecting and take out impurity and the impure fiber in the textile fiber stream by gate system, existing in recent years many schemes.DE4131188 discloses the very simple sorting mode of the gate system of a kind of utilization in the rectangle transfer passage.If it is to impurity, just jet in the respective point in downstream across the valve that the transfer passage width is provided with in upstream detection.Valve nozzle is jet perpendicular to the direction of fiber-air mixture flow, so that impurity is blown and penetrates and by accurately being arranged on the slit on nozzle opposite.
Although this set is in the first impression work, yet there is shortcoming in practice really in it.To enter air mass flow and pressure that the opposite slit needs very high for bath in order to force impurity break away to flow.Because the air mass flow height, impurity is around the collecting chamber rotation and often return air flow in undesirable mode.The objective of the invention is to invent a kind of device, this installs with simple and reliable mechanical system, guarantees that impurity optionally is removed from fiber-air flow by gate mechanism.
According to the present invention, this will realize by the deflection of fiber transmission channel.This will describe on the basis of Fig. 1.Fiber is separated by at least one opening roller, and enters transfer passage, and this passage is preferably rectangular, and for example it is of a size of the wide and 30mm height of 1600mm.In this fiber transmission channel Z, or be positioned at this separate roller place, by video camera K or a series of sensor, fibre stream is monitored at an observation window S place.In case sensor system senses is to impurity, one or more valves will be activated in respective point, and the ejection air.
Optionally blow out the effect that impure fiber is subjected to the baffle plate of fiber bump.Fiber is advanced in a passage, is subjected to the detection of sensing system therein.The suction sorting is in another direct of travel, but not the detected direction of fiber.Turn from its direct of travel in order to help fiber, establish a baffle plate in this path of travel, this baffle plate helps fiber to be deflected new direct of travel.For example, if the direct of travel between detection period or before the deflection is a level, fiber will be extracted out vertically upward.The position of this baffle plate needs and the about angle at 45 of suction sorting direction.Fiber clashes into this baffle plate, and is under normal circumstances upwards extracted out.If impurity is gone out by the sensor of reference point, a valve is activated above baffle plate, and this valve ejects the air flow of shaping downwards along baffle surface by a nozzle.The impurity that is clashing into is pullled by under the air flow, enters collection container by a slit.Impurity is transported to container handling or aspirates separation system by one from collection container by a brood of eye wheel.
Characteristics of the present invention are that compressed air consumption is very low, the reliability height of air-lock sorting.
The present invention will be illustrated on the basis of accompanying drawing 1.
Fiber is inhaled into via suction channel A.This passage is made of window S at two places, and video camera K is by this windows detecting fiber.Fiber is advanced with 4 to 15m/s speed, by inlet suction passage A.Fiber impingement baffles P, and be deflected and enter suction sorting part B, the position of this baffle plate becomes an a angle with suction passage A.
If sensor is to impurity, at least one the valve V among the valve row blows, and by sending shaping air jet towards slot H along the nozzle of the baffle surface that turns to fiber to fiber.This slit is made of the end of baffle plate P and suction inlet passage A.
Fiber and impure fiber are braked by bump, so can be deflected into slot H under the low relatively air flow of pressure.Impurity enters transfer container Z.This transfer container is by nest eye wheel W and isolated from atmosphere.Impurity enters collection container L by the unit wheel of carrying the gate form subsequently.
