Floating sheet article thickness detecting device

A sheet article processing mechanism comprising:

• a sheet article feeding channel;
• a frame having a hollow portion and disposed in front of an entrance of said sheet article feeding channel for allowing a sheet article to be fed into said sheet article feeding channel through said hollow portion;
• two glidable guide blocks respectively embedded into two guiding slots in two side plates of said frame;
• a stationary sustaining element penetrating through and fixed in corresponding fixing holes of said glidable guide blocks such that a sustaining part of said stationary sustaining element is sustained against a first surface of said sheet article;
• a movable sustaining element movably penetrating through corresponding transverse gliding holes of said glidable guide blocks such that another sustaining part of said movable sustaining element is sustained against a second surface of said sheet article;
• at least one elastic element arranged on the same surface of a side plate and between a first end of said stationary sustaining element and a second end of said movable sustaining element, wherein said movable sustaining element is subject to a thickness shift along said transverse gliding holes by said elastic element, thereby clamping said sheet article of different thickness;
• and
• at least one thickness sensing module disposed in the vicinity of said movable sustaining element, wherein said thickness sensing module is synchronously moved with said thickness shift of said movable sustaining element, thereby generating a thickness detecting signal,
• wherein a mobile gap is defined between each glidable guide block and the corresponding guiding slot, such that synchronous shift actions of said glidable guide blocks are allowable in said guiding slots when a processing operation is performed on a front edge of said sheet article transporting through said sheet article feeding channel and a rear edge of said sheet article is subject to a flapping effect, thereby alleviating the influence of said flapping effect, and enlargement of said flapping effect is limited by said guiding slots.

A sheet article processing mechanism comprising:

• a main body having a sheet article feeding channel allowing a sheet article to be fed thereinto, wherein two guiding slots are respectively formed in two side plates of said main body;
• a floating clamp member for clamping said sheet article and including two glidable guide blocks at bilateral sides thereof to be respectively embedded into said two guiding slots, wherein a mobile gap is defined between each glidable guide block and the corresponding guiding slot;
• at least one thickness sensing module disposed on a surface of one of said two glidable guide blocks and in the vicinity of said floating clamp member, wherein said thickness sensing module is synchronously moved with a thickness shift of said floating clamp member according to the thickness of said sheet article, thereby generating a thickness detecting signal, and
• wherein a clamp force by said floating clamp member is greater than a flapping force resulted from a flapping effect of said sheet article and said flapping force is greater than a friction force generated by said glidable guide block, such that said sheet article is stably clamped within said floating clamp member and said two glidable guide blocks of said floating clamp member are synchronously moved in said mobile gap in response to said flapping force.
