Abstract: In an indoor air cleaner according to the present invention, shavings 10 generated when a copper material is cut with a lathe or milling machine are stored inside a breathable net 11. The copper material may be pure copper or various copper alloys. The net 11 may be formed into a spherical shape and hung, or the net may be formed into a container and placed on a desk or the like. When airborne bacteria and viruses in a room come into contact with the surfaces of the shavings 10, the antibacterial and antiviral effects of copper can reduce the activity of the bacteria and viruses.

The nozzle cleaner device is for removing spatter attached to a tip end of a nozzle of an electrode for arc welding, including a main body provided within an operation area of a robot arm which operates the electrode, the main body of the cleaner device includes a tub-shaped box body and a polishing part erected at a center part of the bottom surface of the box body; the polishing part is made of a material softer than a metal which constitutes the nozzle, and formed in a cylinder shape that can be inserted into the nozzle; and the nozzle onto which spatter is attached is carried to the main body of the cleaner device to remove the spatter by means of the polishing part inserted into the nozzle.

Abstract: The present invention relates to a cap tip detachment device capable of detaching cap tips which are fitted at the end of the shanks of a welding device. A pair of nail mounting boards, which mounts a fixed nail, a movable nail, and a slider, which is located between the nail mounting boards, are arranged on a linear rail. The movable nail of the pair of nail mounting boards includes a an arm extending toward an opposite side of a pivot shaft, and a spring that elastically urges the arm in a direction of separating from the nail mounting boards; and a distal end of each arm is abutted against the slider. When a shank is pushed against the fixed nail of one nail mounting board by a robot, the movable nails of both nail mounting boards open allowing the cap tip to be detached.

Abstract: A contact chip for welding, having a housing member with a tapered tip, an abrasion-resistant core member in the housing member, and an adapter member at the rear end of the housing member. The housing member has a first insertion hole as an outlet for a welding wire. The core member has a second insertion hole through which the welding wire is inserted. The adapter member has a third insertion hole through which the welding wire is inserted, and also has on the inner wall surface of its tip end part a taper surface whose diameter gradually decreases toward the tip end so that a space part is formed in the front of the core member. The welding wire is inserted through the first to third insertion holes and the space part so that the wire protrudes from the tip end of the contact chip.

Abstract: The present invention relates to a cap tip detachment device capable of detaching cap tips 60 which are fitted at the end of the shanks 50 of a welding device. A pair of nail mounting boards 3 and 4, which mounts a fixed nail 8 and a movable nail 12, and a slider 5, which is located between the nail mounting boards, are arranged on a linear rail 2. The movable nail 12 of the pair of nail mounting boards 3 and 4 includes an arm 14 extending toward an opposite side of a pivot shaft 11, and a spring 16 that elastically urges the arm 14 in a direction of separating from the nail mounting board 3 and 4; and a distal end of each arm is abutted against the slider 5. When a shank 50 is pushed against the fixed nail 8 of one nail mounting board 3 by a robot, the movable nails 12 of both nail mounting boards 3 and 4 open allowing the cap tip 60 to be detached.

Abstract: An electrode tip magazine for a spot welder that does not interfere with the welding gun is provided. The magazine includes a magazine body formed with a storage part slidably aligning and storing a plurality of electrode tips therein, one end of this storage part serving as an externally opened supply port, a push-out member disposed to be freely slidable between both ends inside the storage part, a pulley disposed at a position adjacent to the supply port of the magazine body, a spiral spring disposed at a position at the other end of the storage part of the magazine body, and a wire connecting a distal end of the spiral spring and the push-out member with an intermediate portion thereof being wound around the pulley so as to always pull the push-out member toward the supply port by a biasing force of the spiral spring.

Abstract: A magazine for spot welding electrodes that stores mini chips and can feed the mini chips one by one. A mini chip storage portion and a cap chip storage portion slidably aligning and storing a plurality of mini chips and a plurality of cap chips are formed such that the mini chip storage portion and cap chip storage portion communicate with each other at one of their ends, where they open to the outside to serve as a supply port. When an arm is inserted into the supply port, a cap chip is mounted to the arm, as well as the cap chip presses the mini chip so that the mini chip is also mounted to the chip base. When the mounting operation is complete, a push-out member pushes the mini chips and cap chips so that the mini chips and cap chips are automatically fed to the supply port.

Abstract: An electrode unit of a spot welding machine in which a recessed fitting portion having a circular shape in section is formed in a surface of a projecting portion of an electrode holder. A first groove is formed in an inner peripheral surface of the recessed fitting portion. A cooling water passage continuous to the recessed fitting portion is formed in the electrode holder. A columnar fitting portion is formed in a base end of the abutting portion of the electrode. A second groove is formed in an outer peripheral surface of the fitting portion. The fitting portion is inserted in the recessed fitting portion. An O ring is fitted in the first groove and the second groove. Then the electrode is attached to the projecting portion. A cooling water circulated in the cooling water passage cools down the electrode and the projecting portion.

Abstract: This invention provides a swing type electrode chip replacement apparatus which enables an electrode chip to be attached/detached without damaging a shank even if the shank is bent. The swing type electrode chip replacement apparatus comprises a fixed plate 20 located in the vicinity of a spot welding machine and a movable plate 21 slidable in the back-forth direction on the fixed plate 20, its front end being swingable in the right-left direction. An attaching unit 1 for attaching an electrode chip 95 to the tip of a shank 90 of a spot welding machine or a magazine of the electrode chip 60 for removing the electrode chip 95 is loaded on this movable plate 21, which is slidable in the back-forth direction and swingable in the right-left direction when the shank 90 comes into contact with the attaching unit 1 or the magazine of electrode chips 60.

Abstract: A cap tip detaching apparatus for a resistance welding machine that detaches a cap tip fitted to a shank of the resistance welding machine. The apparatus includes a pawl portion including a fixed pawl and a movable pawl. The fixed pawl extends in a direction orthogonal to the shank axis so as to be brought into close contact with a lower end portion of the shank. The movable pawl, forming a pair with the fixed pawl, is provided in a leading end of a leverage type lever and is brought into close contact with an upper end portion of the cap tip. A drive portion is included for moving the pawl portion to a portion between the shank and the cap tip. A rotating mechanism, working with the drive portion, rotates the lever to disconnect the cap tip from the shank by pushing down the movable pawl.
