Definitions

• the invention refers to a system for the corner stitching of a wooden strip on boxes. Its prin ciple of operation is based on drive transmission by two shafts resulting in the movement plates, so that two of these plates drive wire to a suitable position for initial cutting, forming in a “P” shape and final placement for stapling.
• the invention refers to a system for corner stitching of a wooden strip on a box made of wood or compressed paperboard box, where shafts drive a set of parts, to achieve cutting and final shaping of wire so that it can be stapled.
• the transmission ratio between plates is a measure of paramount importance, in order to achieve the proper position of the wire before cutting and forming, and ensures that the wire is ready for stapling.
• Figure 1 shows a front view of the mecha nism.
• Figure 2 shows a plan view and isometric sectional view of the mechanism.
• Figure 3 shows the individual parts of the stitching head subsystem.
• Figure 4 shows a front view and transverse sectional view of the stitching head with the cap removed.
• the shaft (1) provides movement through a splined hub to part (2); in turn, this drives the eccentric perforated part (3).
• Part (3) rotates, thus transmitting motion to part (4) located around it; the latter, in turn propels and sends part (5), located above, in elliptical orbit.
• Part (5) is using pins (7) and (9) to link to arms (6) and (10), respectively.
• the arm (6) is con nected by articulated joint to pin (8) and drives the stitching head via the chain lock (23).
• the arm (10) utilizes the pin (11) to drive part (12); the latter, via the pin (14) transmits drive to part (46).
• the movement of part (19) is also determined by part (15), which can be adjusted manually during the setup of the whole system.
• part (15) due to its eccentric structure can be rotated within its allowed angle, causing displacement of part (19).
• Part (17) travels independently through (18), between these two parts (19).
• Part (17) holds and forces the work piece to be stapled, at the appropriate moment.
• Chain sprocket (50), supported on part (2), utilizes a chain to transmit movement to sprocket (51). This, in turn, thanks to its position on the shaft (21) forces the latter to rotate.
• the movement of part (17) is transmitted through the shaft (21).
• the latter has been specifically formed, which allows part (22), which is indirectly coupled to (17), to slide on its guide curvature (21).
• the tension spring (56), through parts (54), is coupled to shafts (55) & (57).
• Shaft (55), drawn by spring (56), is coupled to part (22).
• spring (56) instantaneously pulls shaft (55).
• the result of the latter is that part (17), indirectly linked to shaft (55) travels very rapidly and forcefully, so as to get in sync with the stitching rate.
• the chain lock (23) is mated to part (24), which is coupled to part (25), screwed on plate (26).
• Plate (26) supports the articulated attachment of parts (36) & (37); these are designated as “staplers” by the manufacturer, thanks to their ability to staple the wire on the wood pieces in order to join them together.
• Drive is transmitted to plates (32) & (33) through parts (28) & (30) which are joined with pins (29) & (31) respectively.
• pins (29) & (31) are embedded in the mount of the head (45).
• parts (27) follow the contoured guiding paths of the grooves made on the plates (26), (32) & (33), thus ensuring their synchronized motion and achieving the required effect.
• Wire is fed through part (52) at a specific position, while plates are returning to their original position, before the stitching movement has started.
• Part (53) is used for wire retention and guidance.
• part (42) refers to part (42) as the “former”, due to its purpose of forming the wire into the shape of a "P”, so that the wire can follow its path and obtain its final shape through parts (38), (39) & (41).
• Parts (41) & (42) are under constant pressure applied by the elastic metal sheet plates (44) & (43) respectively, to develop the force to allow their rebound to the initial position.
• the manufacturer refers to part (35) as the “cutter” since its purpose is wire cutting.
• the cutter (35) is coupled to plate (33) through part (34).
