摘要:
A method for sealing insulating glass blanks (1), in which a sealing compound (3) is introduced from a sealing nozzle (7) into the outwardly open edge joint (2) of the insulating glass blank (1). A material tongue (15) of the sealing compound (3) emerging from the sealing nozzle (7) forms in front of the sealing nozzle (7). The size of the material tongue (15) is proportional to the amount of the sealing compound (3) introduced into the edge joint (2) per unit of time. Sealing is controlled in accordance with the length of the material tongue (15) detected by a sensor (10). In particular the amount of sealing compound (3) introduced per unit of time to the sealing nozzle (7) and/or the relative speed between the insulating glass blank (1) and the sealing nozzle (7) is controlled in accordance with the length of the material tongue (15) detected by the sensor (10).

Modular devices for jetting a fluid material and components for modular jetting devices. The devices may include a pressurized air or positive displacement pump fluid supply module to supply a fluid module inlet. A syringe may feed material through a check valve to a positive displacement pump, which feeds material through another check valve to the fluid module. Inside the fluid module is a valve element moved to contact a valve seat and jet a droplet of material by contact between an external drive pin and a movable element of the fluid module. Either a piezoelectric actuator, a pneumatic actuator, or another actuator may move the drive pin. A controller may coordinate the supply of fluid from the positive displacement pump with the rate at which material is jetted. The fluid module and positive displacement pump are easily removable from the jetting device.

The present invention discloses a feed system with a constant pressure. The feed system comprises a feed container which has a depressurize port mounted on its top, a intake port mounted at its side, and a feed port mounted on its bottom, contains a liquid material being a medicine or a liquid glue mixture; a intake structure which comprises a throttle pipeline and a throttle valve; a opening controller which connects to the throttle valve and the pressure sensor, for controlling the intake structure. The advantage of the feed system is to control the feed flow rate so as to maintain a constant during the feed process, particularly in the hybrid feed system. By steadily controlling the output flow rate, the mixed proportion is controlled to generate the product with the stable quality when two or more liquid materials must be mixed according to the specific proportion.
