Abstract: A door-type automatic material-taking device includes a feed table for holding workpieces and a material-taking mechanism having a lifting unit, a linear displacement unit and a robotic arm. The lifting unit has a fixed member, a sliding member and a positioning member. The fixed member is fixed to the feed table. The sliding member moves vertically with respect to the fixed member. The positioning member is deposited between the fixed member and the sliding member, for positioning the sliding member with respect to the fixed member. The linear displacement unit is attached to the sliding member, for moving the robotic arm along X, V and Z axes to take and place workpieces. The automatic material-taking device is adaptive to machine tools of various specifications, making it suitable for standardized and mass production, and helpful to reduce costs for development and installation, thereby providing economic benefits.

Abstract: A front door-type automatic material-taking device includes a feed table, a material-taking mechanism and a sliding mechanism. The feed table is positioned in front of a machine tool and serves to hold workpieces. The material-taking mechanism includes a linear displacement unit and a robotic arm. The linear displacement unit is fixed to the feed table, and drives the robotic arm to move along a first axis, a second axis, and a third axis and to rotate against the first axis up to a specific angle. The material-taking mechanism is slidably attached to the sliding mechanism for sliding away from the front of the machine tool. The disclosed feed table has good stability, thereby enabling the material-taking mechanism to take and place workpieces with enhanced precision, and the sliding mechanism allows the feed table to perform prompt movement, thereby improving working efficiency.

Abstract: A bilateral door-type automatic material-taking device includes a feed table located between two machine tools and a material-taking mechanism having a lifting unit, a linear displacement unit and a robotic arm. The lifting unit has a fixed member, a sliding member and a positioning member. The fixed member is fixed to the feed table. The sliding member is configured to move vertically with respect to the fixed member. The positioning member is deposited between the fixed member and the sliding member position the sliding member with respect to the fixed member. The linear displacement unit is attached to the sliding member, for moving the robotic arm along X, Y and Z axes to take and place workpieces between the feed table and the machine tools. Thereby, the automatic material-taking device helps to reduce costs for equipment deployment, and is suitable for standardized and mass production, thereby providing economic benefits.

Abstract: An indicator device is used in a machine for indicating the operation status of the machine. The indicator device includes a body detachably mounted to the machine, a plurality of circuit boards, which are detachably electrically coupled together, mounted inside the body and each provided with a plurality of light emitting elements arranged in a line, and a controller electrically connected to the circuit boards for controlling on/off status of the light emitting elements subject to the operation status of the machine.

Abstract: A bar feeder includes a feeder tube mounted on a machine base, a transmission mechanism, a driving mechanism having a rotary shaft, a projecting rod connected to the driving mechanism and rotatable with the rotary shaft to engage or disengage from the transmission mechanism, a pushing rod, and a driven mechanism rotatable with the rotary shaft to move the pushing rod into engagement or away from the transmission mechanism. When the pushing rod and the transmission mechanism are coupled together, the pushing rod is movable along the feeder tube, and the projecting rod is disengaged from the transmission mechanism and moved away from the feeder tube. When the pushing rod and the transmission mechanism are disconnected, the pushing rod is not movable along the feeder tube, and the projecting rod is coupled to the transmission mechanism and movable along the feeder tube.

Abstract: For use in a bar feeder, a feeder tube is disclosed to include a holder base and a plurality of support members. The holder base has two hinged holder members each having retaining portions. Each support member has positioning portions respectively detachably engaged with the retaining portions of the holder members, and a bearing portion. The bearing portions of the support members define a cylindrical accommodation space for receiving a bar material therein when the two holder members are close.
