Flat Workpiece Transport System with Height-Adjustable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag manufacturing devices face limitations due to the design of transport systems, which cause hose pieces to be compressed and potentially damaged during the transition from longitudinal to transverse transport, leading to reduced efficiency and performance.
Innovation Solution
The solution involves advancing the subsequent hose piece by a certain distance while the preceding piece is moved in a shorter distance than its width, allowing for immediate transport of the next piece without waiting for the previous one to clear the support surface, and using height-adjustable support surfaces to guide the hose over interfering edges without contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hose piece is advanced in the longitudinal direction using a support surface, then the hose can be transported to the transverse transport level, but the hose piece is compressed and potentially damaged by interfering edges
Solution Approach 1:
The patent introduces a height dimension to the support surface, making it height-adjustable relative to the transport level. This allows the support surface to be positioned at different heights during the transport process, enabling the hose to be guided over interfering edges without contact while avoiding compression damage.
2Ease of operation
If the support surface is designed with interfering edges to guide the hose, then the hose can be directed to the transverse transport level, but the hose bumps or is pushed causing compression
Solution Approach 1:
The support surface is made height-adjustable, allowing its position to be dynamically changed during the transport process. This dynamic adjustment enables the support surface to adapt to different stages of hose transport, providing guidance when needed while avoiding compression by adjusting its height relative to the hose and transport level.
3Productivity
If the hose piece is completely removed from the support surface before the next piece is advanced, then the next piece can be transported immediately, but the distance between hose pieces increases
Solution Approach 1:
The patent enables preliminary action by allowing the next hose piece to be advanced while the previous piece is still partially on the support surface. The height-adjustable support surface allows the leading end of the next hose to be positioned without waiting for the previous hose to completely clear the support, thereby reducing the distance between hose pieces and increasing throughput.
4Ease of operation
If the support surface is lowered to allow hose transport, then the hose can be moved to the transverse level, but the hose receives no support during transport
Solution Approach 1:
The support surface is made height-adjustable, allowing it to be dynamically positioned during the transport process. This enables the support surface to provide stability when needed while allowing the hose to be moved to the transverse transport level, combining both support and transport capabilities.

AI summary
The invention describes a method for changing the transporting direction of successive flat workpieces in a device for transporting flat workpieces (2, 22) with a workpiece width (B), in particular of hose sections (2, 22) - in which flat workpieces (2, 22) are advanced onto a supporting surface (13) in a first transporting direction (z) by means of an advancing device (19),-in which in each case a flat workpiece (2, 22) is conveyed from the supporting surface (13) by means of a transfer device (20, 24-27) in a second transporting direction (x) which is parallel to the plane of the flat workpiece (2, 22) and extends orthogonally with respect to the first transporting direction (z), wherein, directly before and/or during the transport in this transporting direction (x), the flat workpiece (2, 22) bears, at least with its side regions on a transport plane (20) of the transfer device (20, 24 - 27). A following flat workpiece (2, 22) is advanced at least by a certain distance (?z), while the workpiece running ahead is transported on in the second transporting direction (x) by a distance (?x) which is shorter than the workpiece width (B).
