Problems solved by technology

However, it was found that the motion control of the door could not be coordinated tightly enough with the amount of movement of the robot, and as a result, the door of the moving hood compartment was occasionally opened too late or not at all, causing the manipulator to collide with the closed moving hood door, by This may damage the weighing system of the filter

Embodiment Construction

[0026] figure 1 A three-dimensional general view of a filter weighing system 1 equipped with a door opening device according to the invention is shown, wherein the entire system is arranged on a base plate 2 with height adjustment feet 3 . In the right part of the figure a robot 4 is shown with a carrying fork 5 which is movable in the x-y-z direction of a Cartesian coordinate system. Arranged opposite the robot is a holder 6 for a filter weighing receptacle 7 containing a filter 8 to be weighed (cf. Figure 1a ). A microbalance 11 oriented diagonally to the base plate 2 can be seen on the left in the foreground, with a mobile housing housing 12 and a vertically movable mobile housing door 13 . On the right side of the microbalance 11 is the transfer mechanism 15, which represents the Figures 2 to 5 The main part of the door opening device 14 shown in detail.

Abstract

A device (14) allows a door of a balance draft shield enclosure (12) to be activated by a carrier fork (4) of a robot (5). The vertically movable draft shield door (13) sets open an access opening in a raised position and closes the opening in a lowered position. A door-lifter with a force-application element (41) is connected to the draft shield door for application of an upward-directed vertical force. A transmitting mechanism (15), standing clear of the balance (11) includes a force-receiving element (20, 21, 26, 27) that is moved vertically by the carrier fork, between upper and lower end positions. It further includes at least one direction-reversing element (22, 23, 24, 25, 29), coupled to the force-receiving element for coupling to the force-application element, a return spring (28), and a spring-biased locking latch (30).

Description

technical field [0001] The present invention relates to an automatic mechanical actuation device for opening and closing the door of a mobile housing compartment of an analytical or microanalytical balance for use in an automated laboratory system. The invention also relates to a method for opening and closing a door of a mobile hood designed according to the invention. Background technique [0002] Automated laboratory systems in which weighing processes are carried out by means of robots are known from the prior art. Said systems are generally used in situations in which weighing operations are carried out continuously in large numbers, where automation brings savings in labor costs and increased reliability. [0003] A typical example of an automated continuous weighing process occurs in filter weighing for air pollution testing, eg for diesel engines. In said detection, the exhaust gas to be detected is passed through a filter which traps solid particles, in particular...
