  • Patent number: 10538048
    Abstract: Disclosed herein are an electric press and a method for calibrating the electric press, which can implement a rapid calibration operation. An electric press (10) includes a ram location information storage unit (63) and a load control unit (64). The ram location information storage unit (63) stores ram location information, corresponding to actual load values and representing locations to which a ram is moved, in advance. The load control unit (64) applies an actual load, corresponding to at least one location which belongs to the locations represented by the ram location information and to which the ram is moved, to a compression target by moving the ram to the location. Accordingly, the load value output by the detection unit is calibrated based on the actual load value applied to the compression target.

  • Patent number: 10513811
    Abstract: The present invention provides a sewing machine enabling to sew a high-quality pattern without using an embroidery frame. In a sewing machine 1, a pattern is sewn while a fabric 100 is fed in a sewing direction by a feed dog 2a. The sewing machine 1 has a fabric guide 14. The fabric guide 14 has a guide portion 16 which extends straight in a sewing direction to serve as a basis of a cloth feed in an amplitude direction of the needle. The carriage 10 makes the fabric guide 14 slide in the amplitude direction of the needle by a predetermined distance. Thus, the guide portion 16 serves as an index of the position of the fabric 100 to be located for sewing the next pattern line. Since the fabric 100 can be accurately located for sewing the next pattern line, high-quality pattern can be sewn.

  • Patent number: 10472755
    Abstract: A sewing machine includes an embroidery data memory unit, a suspension timing selecting unit, and a suspension control unit. The embroidery data memory unit stores embroidery data, and accepts a planned suspension timing, a sewing suspending instruction, and a sewing resuming instruction. The suspension timing selecting unit selects a discontinuous operation that breaks the continuity of seams within the predetermined range before and after the planned suspension timing from the embroidery data. The suspension control unit maintains the deactivation of a sewing-machine motor until the suspending instruction or the resuming instruction is input when the selected discontinuous operation by the suspension timing selecting unit comes during the sewing of embroidery pattern.

  • Patent number: 10391730
    Abstract: A number of pulses output from an encoder is counted, a number of pulses output from a command pulse output unit is counted, and a difference between the number of pulses that has been counted by the command pulse counting unit and the number of pulses from the encoder is calculated. Then, a condition is changed such that speed/acceleration of a pulse motor increases when a difference value between a deviation threshold and the difference is smaller than a predetermined range, and the speed/acceleration of the pulse motor decreases when the difference value is greater than the predetermined range, and whereby the pulse motor is controlled based on a position of a slider detected by a slider position detection unit, a position of the slider that has been set, and the pulse condition that has been changed.

  • Patent number: 10391729
    Abstract: There is provided a servo press capable of performing press working with high accuracy without an increased cost, for example, without any additional special component such as a linear encoder or the like even in a system in which deviation occurs due to disturbances, as well as a control method and a program disturbance. A sensing element is disposed at a stop position of a slide. A servomotor control unit performs: semi-closed loop control based on information detected by a first slide position detection unit disposed at a servomotor, before a signal detection unit detects a signal from the sensing element, and full-closed loop control based on information detected by a second slide position detection unit, after the signal detection unit detects the signal from the sensing element.

  • Patent number: 10392736
    Abstract: A sewing machine includes a first image acquisition unit, a second image acquisition unit, and a display unit. In the sewing machine, the first image acquisition performs image acquisition from the front face side of a cloth for a stitching pattern formed in the cloth. The second image acquisition unit performs image acquisition from the back face side of the cloth such that the center position of the acquired image matches the center position of the image of the stitching pattern acquired by the first image acquisition unit. The display unit displays, on the same screen, a first stitching pattern video image thus acquired by the first image acquisition unit and a second stitching pattern video image thus acquired by the second image acquisition unit.

  • Patent number: 10331456
    Abstract: A loading order according to which function modules are to be loaded from a storage unit is determined based on a predicted use situation of a user. The function modules are loaded according to the loading order thus determined. Subsequently, the function modules thus loaded are started up according to a start-up instruction. With such an arrangement, by determining the loading order based on a prediction of the user's desired function, such an arrangement enables a reduction in the length of a loading time that bothers the user.

  • Patent number: 10174449
    Abstract: A sewing machine moves a presser foot up and down through a presser-bar lifting lever to depress a cloth. The lever is moved down by a stepping motor at a constant move-down amount. A compression spring is present between the stepping motor and the presser foot. The compression spring is compressed by some of the constant move-down amount of the lever, and applies, to the presser foot, pushing force canceling repulsive force from the depressed cloth. The move-down amount of the presser foot is detected by an encoder, and a thickness of the cloth is calculated by a cloth-thickness calculator. The cloth-thickness calculator performs calculation based on the move-down amounts at two timings in a time period at which the presser foot depresses the cloth and attempts to further move down.
