Printing Plate Textile Release Using A Gripper And Detachment Slide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In textile printing, particularly in direct and screen printing with multiple colors, the manual removal of textiles from printing plates is inconvenient and risky, as it can damage the print image due to uneven stress, and automatic removal is not feasible with existing adhesive film systems.
Innovation Solution
A device with a lifting gripper and detachment slide is used to grip and lift the textile, allowing even separation from the adhesive film, enabling both manual and automatic removal, and is integrated into a printing machine for seamless integration with multi-color printing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual removal of textile from printing plate is used, then the textile can be removed, but the print image may be damaged due to uneven stress and the process is time-consuming
Solution Approach 1:
A detachment slide is introduced as an intermediary tool between the textile and the operator. The slide is inserted between the printing plate and the textile, allowing the textile to be detached evenly from the adhesive film without direct manual handling that could cause uneven stress and damage to the print image
Solution Approach 2:
The detachment function is extracted from the manual removal process. The detachment slide performs the extraction of the textile from the printing plate by sliding between the adhesive film and the textile, separating the detaching action from direct manual manipulation
2Productivity
If automatic removal is implemented, then productivity increases, but the adhesive film system prevents feasible automatic removal
Solution Approach 1:
The detachment slide serves as a mediator that enables automatic removal systems to work with the adhesive film system. By inserting the slide between the printing plate and textile, it creates a mechanical interface that allows automated systems to detach textiles without directly interacting with the adhesive film
Solution Approach 2:
The removal process is segmented into two distinct phases: first, the detachment slide detaches the textile from the adhesive film on the printing plate, and second, the textile is automatically removed and transferred to the drying tunnel. This segmentation makes automatic removal feasible by separating the adhesive release function from the transfer function
3Stability of the object's composition
If double-sided adhesive film is applied to prevent textile slipping, then printing stability improves, but textile removal becomes difficult and time-consuming
Solution Approach 1:
The detachment slide acts as a mediator that interfaces with the adhesive film system. It is inserted between the printing plate and the textile, allowing the adhesive film to maintain its gripping function during printing while enabling controlled detachment during removal by sliding between the adhesive layers
Solution Approach 2:
The system transitions from a static adhesive bonding state during printing to a dynamic detachment state during removal. The detachment slide introduces dynamic motion between the printing plate and textile, allowing controlled separation while the adhesive film maintains its stability during the printing phase

AI summary
The present invention relates to a device for releasing a textile from a printing plate, in particular in direct printing and/or screen printing and/or with several colors, comprising a lifting device which has a gripper for gripping a first end of the textile and a first axis of movement for lifting the gripper; and a release slide which can be inserted via a second axis of movement between the printing plate and the first end of the textile lifted by the lifting device in order to release the textile from the printing plate.
