Solution Overview
Problem
Existing transfer apparatuses for hollow glass articles from a stationary depositing plate to a moving belt conveyor are complex and require multiple rotary drives, leading to intricate control technology and high maintenance due to gear mechanisms, which are prone to reduced lifespan in a harsh environment.
Innovation Solution
A drive system with only two controlled axes and two rotary drives generates a transfer curve through the superposition of these movements, utilizing a rotary table and housing to achieve a safe and efficient transfer with reduced mechanical stress and maintenance, featuring a space-saving design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three rotary drives are used to generate the transfer curve through superposition of three rotational movements, then the transfer precision and control accuracy are improved, but the device complexity and maintenance requirements increase significantly
Solution Approach 1:
The patent extracts and eliminates one rotary drive from the system, reducing from three rotary drives to two. The transfer curve is still achieved through superposition of rotational movements, but now using only two drives (first rotary drive for first rotational movement, second rotary drive for second rotational movement), thereby simplifying the device structure and reducing maintenance requirements while maintaining transfer precision
Solution Approach 2:
The patent combines the functions of the eliminated rotary drive into the remaining two rotary drives. The housing integrates the support structure for both rotary drives, and the superposition of the two rotational movements achieves the same transfer curve that previously required three movements, effectively merging the functionality into a more compact system
2Manufacturing precision
If gear mechanisms are used to transmit rotational movements from stationarily arranged rotary drives, then the transfer curve can be accurately realized, but the reliability decreases due to reduced lifespan in harsh environment
Solution Approach 1:
The patent transitions from stationarily arranged rotary drives with gear mechanisms to a dynamic configuration where at least one rotary drive is arranged on a movable element that moves with the rotary table. This dynamic arrangement eliminates the need for gear mechanisms in the stationary configuration, reducing wear and increasing reliability in the harsh glass molding environment while maintaining transfer curve accuracy through coordinated rotational movements
3Manufacturing precision
If multiple stationarily arranged rotary drives are used, then the transfer curve can be precisely controlled, but the ease of manufacture decreases due to complex construction
Solution Approach 1:
The patent removes one rotary drive and the associated gear mechanism from the system, reducing the number of components that need to be manufactured and assembled. The transfer function is achieved with only two rotary drives, simplifying the manufacturing process and reducing construction complexity while maintaining the ability to precisely control the transfer curve through the superposition of two rotational movements
Solution Approach 2:
The patent makes the rotary table serve multiple functions: it supports the movable rotary drive, provides a reference for positional coordination, and enables the superposition of rotational movements. This multi-functionality reduces the need for separate dedicated components, thereby improving ease of manufacture while maintaining transfer curve control precision

AI summary
An apparatus for pushing hollow glass articles from a depositing plate of an IS glass molding machine onto a belt conveyor comprises a transfer pusher (11), one end of which is rigidly connected to a vertical shaft (10) and the other end of which carries an arrangement of pushing fingers for the glass articles. The shaft (10) is supported in a rotary table (6) and functionally connected to a first rotary drive (13) carried by the rotary table while the rotary plate (6) is mounted on a bell-shaped bearing (24) supported on a console (1) by means of a hollow shaft (22), namely such that it is functionally connected to a second rotary drive (15′). An approximately exponential transfer curve of the pushing fingers that begins at the depositing plate and ends on the belt conveyor and subjects the hollow glass articles to the least possible stress can be realized.
