| 81 | Variable stroke drive system for tufting machine | US14633851 | 2015-02-27 | US09644297B2 | 2017-05-09 | Ricky E. Mathews |
| A variable stroke drive system for a tufting machine includes a series of drive assemblies mounted along the frame of the tufting machine. Primary drive shafts extend through the drive assemblies and are each driven by a drive motor. A series of first drive members are mounted to the primary drive shafts and are linked to associated second drive members such that the driving of the first drive members by the primary drive shafts in turn drives the second drive members. Cam arms are connected to the second drive members and to rocker arms to which push rods are mounted, the cam arms being vertically reciprocated by the rotational movement of the second drive members so as to drive the reciprocation of the push rods, and thus the needle bar(s) connected thereto along a desired stroke or reciprocating path of travel. Controlling the rate at which the primary drive shafts are driven enables control of the stroke of the needle bar(s). | ||||||

| Techniques for controlling sewing machine stitch length based on thread usage are provided. The techniques include a sewing machine computer storing a stitch length setting and using a thread movement sensor to sense the movement of thread as the thread is drawn from a spool due to the user moving an object relative to a sewing machine needle and thereby drawing thread from the needle and the spool. The techniques also include a sewing machine computer receiving information from the thread movement sensor and determining a length of thread drawn from the spool after formation of a previous stitch, comparing the length of thread with the stitch length setting, and operating a sewing machine motor to create a stitch when the length of thread drawn from the spool after formation of the previous stitch corresponds to the stitch length setting. | ||||||

| A drive system for controlling and synchronizing the movement of two or more relatively movable members, one of which is to be driven with any desired amplitude and at any desired rate, and one or more others of which have the movement thereof determined by the movement of the first member. One relatively movable member typically comprises a non-magnetic, electrically conductive armature, such as a reciprocating metal slide operating axially in the air gap between an electromagnetic stator containing plural distributed multiphase windings and a return piece for the flux paths thus generated. Another relatively movable element typically comprises a permanent magnet armature driven by an associated linear actuator also having multiphase windings distributed therein and adapted to create a field of the character indicated by a control signal emanating from a unit detecting the movement of the first movable member. In a described embodiment, the first element includes a carrier for a magnetic sender moving in relation to the coils in a magnetic detector, while the driven or second member includes an amplifier for the signal supplied to it by the detector. As embodied in a sewing machine, for example, the first member or driving element is in the form of a vertically movable slide carrying the needle, and the second or driven member is a horizontally movable armature serving as the bobbin carrier. The needle holder carries the magnet, pickup coils are located adjacent the movement path of the magnet, and the amplifier furnishes amplified pulses of a characteristic type to the windings distributed in the bobbin carrier so as to cause synchronized or slaved movement of the bobbin carrier. Means are typically provided for changing the voltage, current and polarity of the signal applied to the first element stator so as to permit varied movement characteristics to be imparted thereto.
