Hand held twist tie apparatus

A hand held twist tie apparatus for securing products with twist tie material comprising;

• electromechanical mounting and drive means for, mounting, powering, controlling, and activating the apparatus,
• twisting means, contiguously energized by said drive means for twisting the tie material into a tight joint,
• said twisting means further comprise a set of combined hollow and solid shafts having a shaft gear thereon, said shafts having a bifurcated twister head disposed thereon with both shafts positioned adjacent to and simultaneously rotated by said drive means, with the twister head grasping and twisting the tie material when rotated a predetermined number of rotations by the drive means,
• encircling and tightening means attachably shuttled onto said twisting means surrounding the tie material on the product and urging the tie material into intimate contact thereupon,
• feeding, measuring and cutting means contiguously set in motion by said drive means, directing a predetermined amount of tie material into said encircling and tightening means and cutting to length therewith, and
• twist tie material storage and supply means juxtapositioned on said drive and mounting means accommodating a roll of tie material and introducing a free end of the material into said feeding, measuring, and cutting means for securement of a product with a length of tightly twisted tie material.

A hand held twist tie apparatus for securing products with twist tie material comprising;

• a) a mounting frame including an outwardly extending cam plate having opposed recessed grooves, also a product receiving throat,
• b) a drive motor having a shaft gear and motor control means mounted on said frame to supply electromotive force to operate the apparatus and control for the functional operation thereof,
• c) reduction drive gears revolvably affixed to said frame rotatably driven by said drive motor shaft gear for decreasing the motor output speed,
• d) a gear cluster and turntable revolvably affixed to said frame and rotatably driven by said reduction drive gears for providing rotational force and torque to the apparatus,
• e) a twister having a hollow shaft with a shaft gear thereon, a spring loaded solid twister shaft having a bifurcated twister head on one end with the solid shaft disposed within the hollow shaft, both rotatably connected on each end to the frame directly above the gear cluster with turntable also driven thereby, with the twister head grasping and twisting the tie material when rotated a predetermined number of rotations,
• f) a twister drive train rotatably disposed within the frame contiguous with the gear cluster and twister gear for transmitting rotation energy from the gear cluster directly to the twister,
• g) a spring loaded shuttling carriage slideably attached over the twister hollow shaft in communication with the turntable, when the carriage is released by rotation of the turntable, the carriage shuttles along the hollow shaft camming outwardly, as guided by the recessed grooves in the frame cam plate, around the product receiving a predetermined length of cut tie material across an open gap and camming back to surround and hold the product with tie material when the turntable completes a revolution, permitting the twister head to grasp the tie material and twist it therearound,
• h) a feed transport arm having rollers and cutters attached arcably to the frame, the rollers are rotated a predetermined number of revolutions by the gear cluster, advancing the tie material pinched between rollers into the shuttling carriage, also severing a continuous end of the tie material with the cutters at an appropriate time interval triggered by a cam on the gear cluster, and
• i) an enclosure having a handle and a reel holder, said handle connected to the frame structure for gripping said enclosure, encompassing said apparatus for protection from moving parts, said reel holder having a rotatable reel spindle and turn around roller integral therewith, mounted on top of the enclosure for storing a reel of tie material and providing a roller to change direction of the material for introduction into the feed transport arm.
