Device for dispensing material
(57) Abstract:The device (10) for dispensing finely dispersed material (T) can be used for charging of the toner in the photocopier devices and laser printers. The device comprises a hopper (23) for storing fine material (T), an outlet (12), having a distributing nozzle (13), and means of submission (25) designed to transfer the fine material (T) from the hopper to the discharge port (12). The supply of fine material regulate the means of measuring the fine material (T) to regulate the amount of the fine material (T), transmitted by means of submission (25) into the outlet pipe (12). Material (T) is transferred into a refillable container (S), setting it at the dispensing nozzle, so that the tool feed (25) transfers a predetermined amount of fine material (T) from the hopper (23) into the outlet pipe (12). Displaced from the container (C) airflow due to fine material, comes in precipitating pipe (15), where the material contained in the displaced air, settles and falls under gravity into the container (S). This avoids polluting the atmosphere fine with the General invention relates to a device for dispensing and, more specifically, to a device for dispensing fine material, such as toner for Photocopying devices and laser printers.The term "toner" is used in the field of reproduction to denote electrostatic mixture acting as "ink" when forming the image on a flat paper copies.It is known that fine material is difficult to transport when automated processes. This is particularly true in cases when it is necessary to move the material from one container to another. When moving material from one container to another displaced air carries with it a certain amount of fine material. Such an arrangement is often unsatisfactory, because it creates clogged by particles in the atmosphere, which can be dangerous for breathing. In addition, the accumulated material can have a negative impact on the equipment, and cleaning can be difficult.In the famous semi-automated process such, an example of which is implemented in the device Per-Phil (firm "Prefil industries, Inc. (Per-Fil Inductries, Inc.), Riverside, 08075 the state of new Jersey, USA), the fine material is metered from Bouroullec devices, etc. and is used for refilling cartridges that are inserted into specific equipment. Device for dispensing want it otmeryala a predetermined amount of toner in a range of sizes cartridge toner, and it comprises a hopper, a vertically positioned screw and holding the nozzle. This process of filling the empty cartridge hold under the dispense nozzle and rotate the screw to the specified number of revolutions to supply the required quantity of material in the nozzle. It also displaced the air carries with it a certain amount of toner. In addition, because the flow of fine material, similar to the fluid flow, the amount of toner supplied from the screw, may undergo undesirable changes.The present invention is to attempt to overcome the above disadvantages and to develop improved device for dispensing fine material, such as toner.Therefore, the present invention relates to a device for dispensing fine material containing:
a hopper for storage of the dosed material;
the discharge port with transfer of nasasa material from the hopper to the discharge port;
A measure of fine material designed for controlling the amount of material transmitted by means of supply into the exhaust pipe, and
deflecting means, actuated to force the introduction of a container filled with a material in sealed contact with the dispense nozzle
resulting in operation, the sealed container at the dispensing nozzle, means for supplying transfers a predetermined amount of material from the hopper into the exhaust pipe, and displaced air, clogged material from the container comes in precipitating the pipe, where the material contained in the displaced air, settles and falls under gravity into the container.Preferably, the means for supplying includes, essentially, a horizontally positioned screw.Mainly, the auger is positioned so that the fine material, portable, offset, remaining in the auger or returning to the bunker, resulting in the flow of material stops when the auger stops.Typically, the measurement tool includes switching means on the basis of the timer for regulating the number of revolutions šnē the tx2">In a preferred specific embodiment, the outlet and the inlet of the deposition form part of a vertically positioned pipes, flow in which the auger through the connection, remote from the upper end of the pipe. The material falls through the connection in the dispenser nozzle at the lower end of the pipe, and the displaced air escapes up the outlet in the nozzle deposition, where material, portable displaced air, gets the opportunity deposition and fall under gravity into the container, located directly under the dispense nozzle.Mainly, the sealed container at the dispensing nozzle plate having a deflecting means.Typically, a distributing nozzle has a tapered profile to facilitate hermetic contact with the holes for filling containers in a range of sizes.Preferably, there are means to move the material in the bunker.Mainly, the mixing tool is driven by means of submission.The device preferably contains one bunker, a few money supply and the corresponding exhaust pipes.
