Wire Feeding Mechanism With Load Relief for Easy Wire Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines face difficulties in securely mounting wires due to interference from the drive-side feeding member, which can cause collisions and improper wire mounting during the process of winding reinforcing bars with wire.
Innovation Solution
Incorporating a load reducing mechanism, such as a clutch, that allows the drive force to be transmitted only when necessary, enabling the first feeding gear to rotate independently and reducing interference, thus facilitating easier wire mounting between the feeding members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the drive-side feeding member is positioned on the wire feeding path to feed the wire, then the wire can be fed continuously, but the drive-side feeding member interferes with wire mounting and causes collisions
Solution Approach 1:
The drive-side feeding member is designed to be movable between a retracted position (where it does not interfere with wire mounting) and a feeding position (where it contacts the wire for feeding). This dynamic positioning allows the system to switch between mounting mode and feeding mode, resolving the contradiction between continuous feeding and easy mounting.
2Ease of operation
If the driven-side feeding member is moved away from the drive-side feeding member to secure mounting space, then wire mounting space is secured, but the feeding members cannot maintain proper engagement
Solution Approach 1:
The driven-side feeding member is made movable relative to the drive-side feeding member. During wire mounting, the driven-side member is retracted to create sufficient mounting space. During feeding operation, both members are positioned to maintain proper engagement and transmit driving force reliably, thus resolving the contradiction between mounting space and engagement reliability.

AI summary
A binding machine includes a wire feeding unit configured to feed a wire to be wound on an object to be bound and a binding unit configured to twist the wire wound on the object to be bound. The wire feeding unit includes a pair of feeding members configured to sandwich the wire between the pair of feeding members and to feed the wire by a rotating operation, a wire feeding drive unit connected to one feeding member and configured to rotatively drive the one feeding member, and a load reducing part configured to reduce or remove a load, which is to be applied to the wire via the one feeding member, of the wire feeding drive unit.
