Patent number: 10518435Abstract: A feeding system with numerically adjustable pneumatic cylinder speeds includes: a frame; an X-axis pneumatic cylinder; a Z-axis pneumatic cylinder; a feeding table connected to the pneumatic cylinders in order to be driven into motion in the X- and Z-axis directions; an X-axis detection module; a Z-axis detection module; a microcomputer; and a display screen electrically connected to the microcomputer. The microcomputer uses each detection module to determine the time interval between the instant at which the piston rod of the corresponding pneumatic cylinder passes the corresponding starting point and a subsequent instant at which the same piston rod passes the corresponding endpoint. The time intervals thus determined are defined as a duration of X-axis forward movement and a duration of Z-axis forward movement respectively. Both durations are displayed on the display screen.Type: GrantFiled: August 9, 2017Date of Patent: December 31, 2019Assignee: OAV EQUIPMENT AND TOOLS, INC.Inventors: Hsuan-Chu Liu, Long-Chang Jan

Patent number: 9486933Abstract: An emergency stop device for a band saw includes a brake member moveable between a standby position and an active position where the brake member firmly urges and stops a running wheel of the band saw, around which a band saw blade is looped. The brake member is held by a retainer at the standby position when the emergency stop device is inactive. When the emergency stop device is started, the retainer is separated apart from the brake member for enabling the brake member to move by an actuation of a spring member from the standby position to the active position so as to stop the cutting motion of the band saw blade.Type: GrantFiled: January 12, 2010Date of Patent: November 8, 2016Assignee: OAV EQUIPMENT & TOOLS, INC.Inventors: Long-Chang Jan, Hsuan-Chu Liu
