Description

[0001] The present invention relates to an active carbon dropping device for VOCs,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for manufacturing a vapor collector for adsorbing vaporized vapor (VOCs) generated in a fuel tank of an automobile and supplying the vaporized vapor to a vaporizer in a saturated state, Activated carbon pellets were introduced into the container forming the trapping unit, the activated carbon powder was removed, only the pellets in the particle state were injected, and the activated carbon pellets were spread flat by generating vibration in the container. To the activated carbon inlet device for the vapor collector.

The fuel system of a vehicle includes a fuel tank for storing fuel by a device for storing and supplying fuel consumed in the engine, a fuel pump for supplying the fuel in the fuel tank to the vaporizer, a fuel filter for removing impurities of the fuel, And a vapor collector (canister) for collecting the fuel vaporized in the fuel tank.

The main component of the gasoline is hydrocarbon (HC). When the internal pressure rises due to the volume expansion due to the rise in the temperature in the fuel tank, a ventilator is required to prevent it from occurring as a negative pressure is generated. In addition, A vapor gas control device is also needed to prevent this. The vapor capture system is the evaporation gas control system in which activated carbon is embedded. Activated carbon has a characteristic of adsorbing fuel vapor well and releasing fuel vapor again when air is flowing. Therefore, when the engine is stopped, the gaseous fuel is collected in a canister filled with activated carbon. When the engine is operated, fresh air is injected from the outside of the canister to supply the fuel adsorbed by the activated carbon to the intake system of the engine.

Meanwhile, in the prior art, since the work of quantitatively inputting the activated carbon in the manufacturing process of the above-described vapor collector is dependent on the manual operation, not only the productivity is lowered, but also the working environment is poor due to dust generation during the charging process of the activated carbon, There is a possibility that the trapping efficiency of the vapor decreases due to the clogging of the voids between the activated carbons.

There is provided a dust removing unit 20 for removing activated carbon in powdery state, that is, activated carbon dust contained in activated carbon in pellet state stored in the dust collecting container 10 before putting it into a vapor collecting container.

As shown in the front view of FIG. 1, the dust removing unit 20 is disposed so as to intersect an inclined slope 22 so that activated carbon flows down along the slope 22, and the slope 22 The air is blown by the blower 23 installed in the inside of the slope 22 so that the dust can be sucked and removed from the dust suction port 24 provided on the outer side of the slope 22, , The slope (22) and the dust suction port (24) are covered with a mesh having a mesh capable of passing activated carbon in a powder state without passing through the activated carbon pellets in a steady state.

A level sensor 35 is provided on the upper side of the tune-up chute 33. The level sensor 35 is in contact with the activated carbon dropped through the dust removing unit 20, The operation of the bucket conveyor provided in the hopper 10 is stopped so as to stop the supply of activated carbon to be quantitatively measured 31 by the sensing operation (on operation).

In the drawing, reference numeral 36 denotes a shutter 36 which operates when the specification of the activated carbon is changed. The shutter is horizontally slid by the air cylinder 37.

The container input unit 40 includes a container cradle 42, a sliding air cylinder 44 for horizontally feeding the container cradle 42 in the forward and backward directions, And a lifting air cylinder 46 for supplying activated carbon in a state of being closely attached to the metering unit 30 and lowering it to the original position when the supply of activated carbon is completed.

The container input unit 40 is provided with a sensor (not shown) for detecting whether or not the vapor collecting container C is placed in the container placing table 42. In the absence of the container, 44 and 46 are not started. When the container is placed by the sensor, the safety door unit, which will be described later, descends to prevent the dust from being scattered to the outside in the process of injecting the activated carbon.

On the other hand, when the activated carbon is dropped, vibration is generated in the container C by the vibration generating unit 50 provided at the lower part of the container placing table 42, and the dropped activated carbon is flattened and spread.

Then, the level measuring unit 60 is operated to measure the height of the activated carbon contained in the vapor collection container C, thereby filling the activated carbon with a predetermined amount The safety door unit 80 is elevated. When the safety door unit 80 is not filled with a predetermined amount, an alarm sound is generated to the outside or a warning lamp is turned on as described above, so that the operator confirms the warning sound, When the operator fills the container C with the filter F, the operator removes the filter F from the charging device and transfers the filter F to the subsequent cover welding device.

As described above, in the apparatus for injecting activated carbon for a vapor collector according to an embodiment of the present invention, activated carbon in pellet form is charged into a vapor collecting container by a predetermined amount while being automatically metered without filling by hand, The amount of activated carbon can be prevented from being reduced by using the level measuring unit after flattening and spreading by the vibration generating unit even after the setting, The height of the filter can be measured by measuring the height of the filter, and if it is within the set range, the process is advanced to the next process. Therefore, the performance and quality of the vapor collector can be standardized. So that it can be inserted into Since there are advantages such as the speed up of work possible.
