Sewing machine

A sewing machine including a detection portion that detects a movement amount of a workpiece, a sewing machine motor that serves as a driving source for vertical movement of a needle bar, and a control device that controls the sewing machine motor based on the detection result by the detection portion and performs control to maintain a constant stitch pitch. The control device lengthens a period for obtaining an output of the detection portion when the movement amount of the workpiece per unit time based on the detection result by the detection portion is decreased, and shortens the period for obtaining the output of the detection portion when the movement amount of the workpiece per unit time based on the detection result by the detection portion is increased.. ...

Bobbin thread winder of sewing machine and sewing machine

A bobbin thread winder of a sewing machine including a bobbin winder spindle holding a bobbin and a driving mechanism to apply a drive force to the bobbin winder spindle, comprises a time measuring unit to measure an bobbin-thread winding execution time with respect to the bobbin, and a bobbin-thread winding amount calculating unit which calculates a winding amount of the bobbin based on the bobbin-thread winding execution time with respect to the bobbin measured by the time measuring unit. In the bobbin thread winder, since the bobbin-thread winding execution time was measured by the time measuring unit, and the bobbin winding amount of the bobbin is calculated based on the bobbin-thread winding execution time by the bobbin-thread winding amount calculating unit, it is possible to detect the bobbin winding amount of the bobbin accurately regardless of the type and thickness of the bobbin thread.. ...

Sewing machine

A sewing machine includes a feed mechanism which feeds a workpiece by a feed dog partially protruding out upward from an upper surface of a throat plate and moving along a predetermined feeding direction; a presser foot which presses the workpiece on the upper surface of the throat plate from above; a feed guide which has an abutting surface along the feeding direction and guides feeding of the workpiece; and a control device. The feed mechanism includes a lateral feed mechanism which adds a moving component in a direction along the upper surface of the throat plate and orthogonal to the predetermined feeding direction, to the feed dog. ... Juki Corporation

Sewing system

A sewing system comprises a sewing machine, a camera that captures an image of a reference position for sewing, a robot arm that holds the sewing machine and the camera, and a controller. The controller controls operations of forming a first stitch position that results from stitching of the sewing machine, and forming a second stitch position that results from stitching of the sewing machine after rotating the sewing machine at a prescribed angle about a rotation axis that passes through a needle center position stored by the controller. ...

Sewing machine and sewing system

A sewing machine in which a base configured to support a throat plate, a shuttle or a looper, and an input shaft for a stitching operation to the shuttle or the looper with respect to a bed portion of a frame is supported to be movable along a direction of approaching or separating from a sewing needle is provided. The sewing machine includes a connecting member which changes to any one of a state in which the input shaft and a transmission shaft are aligned in the same straight line to be in a torque transmission state and a state in which the input shaft moves together with the base with respect to the transmission shaft, between the input shaft on the base side and the transmission shaft which transmits power to the input shaft.. ... Juki Corporation

Sewing machine

A sewing machine includes a sewing machine motor, a control device and a wearable sensor. The sewing machine motor is a vertical movement driving source of a needle bar. ... Juki Corporation

Sewing machine

A sewing machine includes a vertical shuttle and a middle shuttle presser disposed at a front side of the vertical shuttle. The sewing machine includes a presser frame, an optical upper thread detector and a stitch skipping detection processor. ... Juki Corporation

Sewing machine

A sewing machine includes a sewing machine motor serving as a drive source for driving the vertical movement of a needle bar, a control part for controlling the sewing machine motor such that a sewing pitch coincides with a set value, and imaging part for imaging a seam formed in a workpiece at a needle drop position. The control part obtains the length of the most recent seam from an image of the most recent seam imaged by the imaging part and also compares the length of the most recent seam with the set value of the sewing pitch to thereby correct the number of rotations of the sewing machine motor.. ... Juki Corporation

Managing apparatus

A main management software equipped on a managing apparatus determines electronic components to be mounted by each electronic components mounting machine on the basis of information relating to a board to be manufactured; sends information relating to the electronic components to be mounted to at least one piece of sub-management software or the main management software itself that has, as a management target, the electronic components mounting machine to mount the electronic components; acquires information relating to preset items extracted from calculation results obtained using a manufacturing program for mounting the electronic components and sent from each of the sub-management software and the main management software itself; and adjusts the electronic components to be mounted by each electronic components mounting machine on the basis of the acquired information relating to the items and the information relating to the board to be manufactured.. . ... Juki Corporation

Throat plate switching mechanism

A throat plate switching mechanism includes a first throat plate and a second throat plate. The first throat plate is formed with a first needle hole having an elongated hole shape at a stitch point. ... Juki Corporation

Presser lifting mechanism of a sewing machine

The presser lifting mechanism of a sewing machine includes a cloth presser, a pressing rod which holds the cloth presser by a bottom end portion thereof, a rod holder which is fixed to the pressing rod, a pressing spring a bottom end portion of which is in contact with a top end portion of the rod holder and which pushes the cloth presser downward via the rod holder, a push-up member through which the pressing rod is inserted so as to be movable in the vertical direction and which is in contact with the rod holder from below and can pushed it up, a link body which is in contact with a bottom surface of the rod holder and is connected to the push-up member, and a presser motor which is linked to the link body and serves as a drive source for elevation and lowering of the cloth presser.. . ...
