Plant "UZGK-6M" for filling and sealing of capsules

Description

The UZGK-6M plant for the filling of capsules with granules, compacting of granules and sealing capsules

Detailed information PDF
The UZGK-6M unit is designed to fill capsules with granules, vibratory compaction of granules, thermal degassing and sealing of granules in capsules by subsequent welding of the capsule neck with an electron beam. The UZGK-6M unit is a chamber unit consisting of the following complexes: mechanical, vacuum, energy, automatic control system, gas supply system and cooling system.

Capsules are filled with granules in the intra-chamber space from a transport container through a granule pipeline under vacuum and heating conditions. Degassing of granules and the filled capsule is carried out with simultaneous pumping out of desorbed gases by vacuum pumps of the unit. Granules are heated in a "flying" flow, i.e. a thin layer of powder. The capsule is heated before the filling operation. The capsule with equipment is moved into and out of the chamber by a mechanized trolley along a rail track. The equipment with the capsule is installed using a loader mounted with a trolley on a vibrating rotary table-manipulator and positioned in such a way as to ensure that granules are poured into the capsule neck using the rotary manipulator of the equipment. During the filling process, the capsule with granules is vibrated to achieve the required density and uniformity of granule filling.
The powder is poured from the transport bin through a metal granule pipeline into the granule feed device installed next to the electron beam gun on the movable plate of the gun movement mechanism.
Then the capsule neck is welded with an electron beam. Before removing the capsule from the chamber, inert argon gas is pumped into the chamber to excess pressure, and to accelerate the cooling of the sealed capsule with granules, forced circulation and cooling of the filled gas is carried out through a heat exchanger and a fan heater.

Chamber.
The chamber is designed to accommodate filled and welded capsules, a heating system, create a deep vacuum atmosphere, and create a gas environment for subsequent cooling of the product after welding, input of a granule pipeline with a manipulator, movement by an electron beam gun.
The chamber consists of the main components - a chamber, a heating unit, a tool manipulator, a video device, a granule feed device, a rear cover, a chamber door, an inspection device, a current lead, a lamp, a thermocouple lead.

Forevacuum chamber.
The forevacuum chamber is designed to reinstall the transport container with granules during the process. The unit includes a set of flexible pipelines connected to vacuum pipeline branches, manual powder valves, a pneumatic valve, a cyclone for holding the powder in replaceable filters and control and shut-off devices.

Capsule loading/unloading mechanism.
The mechanism is designed to load/unload the capsule into the working chamber of the unit. Consists of a trolley and a stacker.
The trolley is moved by an electromechanical drive. The stacker lifts and lowers the load.

Vibration unit.
The vibration unit is designed to generate vibration oscillations that are transmitted through the internal rod of the lifting table to the capsule fastening device in the working chamber.

Vibration unit frame.
The frame serves as a supporting structure for the lifting vibrating table and is welded from standard steel sections. The table lifting drive is attached to it and consists of four screws driven by an electric motor through couplings, shafts and a gearbox.

Lifting table.
The unit includes two tables, one of which is the lower, lifting and rotating table, and the other is the upper table, which can move in a vertical plane together with the internal rod, ensuring contact between the vibration motor and the capsule fastening device in the working chamber.
