Litho Laminating Machine Motor Mounting for Accelerator Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Litho laminating machines face a challenge in balancing the need for powerful acceleration of printed sheets onto corrugated cardboard while maintaining a lightweight accelerator table that can be easily moved between operating and maintenance positions.
Innovation Solution
The motor is mounted on the frame with a rotatable transmission element, allowing drive power to be transmitted to the accelerator rollers via a rotating element coaxial with the pivot axis, enabling the table to pivot without disconnecting the drive, and using a belt drive system with a toothed carbon belt for quick acceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the motor is mounted on the accelerator table to provide powerful acceleration, then the acceleration capability is improved, but the weight of the accelerator table increases making it difficult to move
Solution Approach 1:
The drive system is segmented into two parts: the motor remains stationary on the frame while only the lightweight transmission element (pulley) rotates with the accelerator table. This separation allows the table to be moved easily for maintenance while the motor continues to provide powerful acceleration through the rotating transmission element.
Solution Approach 2:
A rotating transmission element (pulley) mounted coaxially with the pivot axis acts as an intermediary between the stationary motor and the accelerator rollers. This intermediary transmits drive power while allowing the table to pivot freely between operating and maintenance positions without disconnecting the drive.
2Device complexity
If the motor is mounted on the accelerator table, then the drive connection is simplified, but the motor must be lifted during position changes causing downtime
Solution Approach 1:
The drive system is divided so that the motor remains fixed on the frame while only the lightweight transmission element rotates with the table. This allows the table to be quickly lifted and repositioned during maintenance without moving the heavy motor, significantly reducing downtime.
Solution Approach 2:
The transmission element is pre-configured to rotate coaxially with the pivot axis, so that when the table needs to be moved to maintenance position, the drive connection is already arranged to remain intact during the lifting operation, eliminating the need for disconnection and reconnection procedures.
3Power
If a heavy motor is mounted on the accelerator table, then the acceleration power is sufficient, but the table becomes difficult to pivot between positions
Solution Approach 1:
The system is segmented into the stationary motor providing acceleration power and the lightweight rotating transmission element that pivots with the table. This segmentation maintains sufficient acceleration power while making the table easy to pivot between operating and maintenance positions.
Solution Approach 2:
The rotating transmission element serves as a lightweight intermediary that transmits the motor's acceleration power to the rollers while being light enough to allow easy pivoting of the table. The intermediary maintains the power transmission function without adding significant weight to the movable table.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for efficient and quick acceleration of the sheets while keeping the motor stationary during position changes, reducing the weight of the accelerator table and maintaining a stable drive connection.
Implementation Method 1
A belt, for example a toothed belt, in particular a carbon belt, is particularly suitable for connecting the accelerator rollers to the drive pulley.
Implementation Method 2
At the accelerator table, at least one tension roller is provided for maintaining the desired tension of the belt drive.
Implementation Method 3
The motor can in particular be an electric motor which can be easily controlled in a very precise manner regarding the speed of rotation.
