Abstract: A stowage system includes: a lock detection sensor detecting an unlocked state where a package can be taken in and out of a second package room which is separated from both an interior space of a vehicle and a first package room formed above the horizontal plane extending along a floor of the interior space, and allows the package to be taken in and out from an outside of the vehicle, or a locked state; an air conditioning device; and a microprocessor. The air conditioning device forms a flow of air in the second package room by a fan. The microprocessor is configured to perform outputting an operation signal to the air conditioning device so that the fan operates when the lock detection sensor detects locking of the second package room in a state where the second package room stows the package.

Abstract: A holding part of a welding gun holds a held part that is provided to an arm having resistance welding electrodes. A first facing part and second facing part of the holding part face each other with the held part therebetween, so as to form a layered part. A connecting part fixes the relative positions of the first facing part and the second facing part. A collar is inserted into a through hole of the first facing part so as to be movable in the layering direction. When a pressing mechanism presses the second facing part, the held part, and the collar in the layering direction, the held part is sandwiched between the second facing part and the collar.

Abstract: Provided are a projection welding device and an electrode cleaning method for the same with which it is possible to keep a stud holding hole formed in a welding electrode clean. A projection welding device welds a stud to a workpiece by holding the stud using a second electrode, bringing the stud into contact with the workpiece, and causing a welding current to flow through the second electrode, wherein the second electrode includes a stud holding hole which extends from a cap opening formed in the distal end, to a bottom portion formed on the base end side, and at least one lateral hole which extends from a side wall opening formed in a side wall to the bottom portion, and the projection welding device is provided with a stud supply device which ejects air into the stud holding hole from the cap opening of the second electrode.

Abstract: Provided are a stud supply device and a stud supply method with which a stud can be supplied to a welding electrode in the correct orientation. The stud supply device comprises: a magazine in which a predetermined number of studs can be aligned and stored in series inside a magazine hole from a stop part to one end side; switching mechanisms having a plurality of balls that can move between a position contacting the studs and a position not contacting the studs, and a reciprocating member that restricts the movement of the plurality of balls, the switching mechanisms switching between a state in which the studs are stopped at the stop part and a state in which the studs are allowed to pass; and a first air injection part that is provided more on the one end side than the stop part, and that injects air from the one end side to the stud stopped at the stop part.

Abstract: A component filling device and a component filling method are provided which, with a configuration that does not involve contact with the workpiece during a stud gun welding operation, can fill a component supply device with a prescribed number of components from a component feeding device. The component filling device (a stud filling device) is provided with: a component storage unit (a tube) which, inside of a component storage hole (the tube hole), can store a prescribed number of components (studs) aligned from a stopping unit towards the top; and a switching mechanism which comprises multiple moving bodies (balls), which can move between a position contacting a component and a position not contacting the component, and a lock unit (a rotation member), which restricts the moving bodies from moving, wherein the switching mechanism can switch between a state in which the stopping unit stops the components and a state in which the components are allowed to pass.

Abstract: A welding gun includes a proximity restricting mechanism that is provided between a shaft and a cover member in a manner to surround the shaft and to be displaceable relative to the shaft in an axial direction in accordance with expansion and contraction of the cover member, and that restricts the cover member from approaching too closely the shaft.

Abstract: A connecting device 1 of a towing vehicle 2 includes a connecting pin 13, a locking arm 22, and an actuator 23. The connecting pin 13 is provided to be rotatable between a connection position where the connecting pin 13 is brought into fitting engagement with a connecting plate 3a of a wheeled platform 3 and a disconnection position where the connecting pin 13 is taken out of the fitting engagement with the connecting plate 3a. The locking arm 22 is driven by the actuator 23 between a locking position where locking arm 22 is locked with the connecting pin 13 such that the connecting pin 13 cannot rotate out of the connection position toward the disconnection position and an unlocking position where the connecting pin 13 is unlocked in the connection position.

Abstract: A welding gun includes: a moving mechanism portion (ball screw mechanism) for moving a movable electrode back and forth; a motor that includes a rotor and drives the moving mechanism portion to move the movable electrode back and forth; and a brake mechanism that prevents rotation of the rotor during a braking operation, wherein the brake mechanism includes an annular brake disc that is attached to an outer peripheral surface of the rotor and rotates integrally with the rotor, and a clamping portion that prevents rotation of the brake disc by clamping the brake disc during the braking operation.

Abstract: The present invention relates to a resistance welding device, a hollow arm, and a method of manufacturing a hollow arm. A welding gun is provided with the hollow arm for holding a movable electrode. The hollow arm includes an arm body having a cavity portion that is opened on one side, and a cover attached to an opening end surface of the arm body so as to cover an opening of the cavity portion. The arm body and the cover are secured by a friction stir welding portion extending along a peripheral part of the cover.

Abstract: The guidepath includes: a magnet guide tape which carries S pole, and guides a carrier vehicle in a first direction by the S pole by being arranged on a floor so as to extend in the first direction; a magnet guide tape which carries S pole, and guides the carrier vehicle in a second direction by the S pole by being arranged on the floor so as to extend in a second direction which intersects the first direction; and a magnetic body tape which is arranged at a side of the magnet guide tape at a position above which a marker sensor passes upon the carrier vehicle being guided by the magnet guide tape, and suppresses N pole.

Abstract: An electrode moving mechanism of a welding gun includes a first mechanism portion that has a shaft, a second mechanism portion that has a housing capable of housing at least a portion of the shaft, and supports the shaft in a manner to be relatively movable in an axial direction, and a cover member that covers at least a portion of the shaft and is capable of expanding and contracting in accordance with relative displacement between the first mechanism portion and the second mechanism portion, wherein a communication path is formed that enables communication between an internal space, which is between the shaft and the cover member, and an internal space of the housing.
