Abstract: A control system configured to control a forklift to unload a transport pallet onto an unloading place includes a control device configured to control at least one of movement of the forklift and horizontal movement of a fork, the forklift including a load sensor configured to detect load of an item placed on the fork, and a lift height sensor configured to detect a lift height of the fork, control raising and lowering of the fork, acquire load information of the transport pallet placed on the fork and lift height range information, the lift height range information indicating a lift height range, the lift height range being a range of height in which the fork is able to be inserted when unloading onto the unloading place is successful, and determine whether an abnormality is present.

Abstract: An integrated control system for an automatic guided vehicle in a vehicle production line includes: a plurality of the automatic guided vehicles each conveying a conveyance object which is a vehicle; a map construction unit that acquires a map of the vehicle production line; a position information acquisition unit that acquires position information of the plurality of the automatic guided vehicles on the map; a production instruction acquisition unit that acquires vehicle information of each of the vehicles conveyed by the plurality of the automatic guided vehicles; and an operation control unit that controls movement of each of the plurality of the automatic guided vehicles on the map based on the position information and the vehicle information.

Abstract: A control device acquires a first two-dimensional position of a cam bolt and a locknut in a first direction based on a first actual image captured by a first camera, and based on the acquired first two-dimensional position, the control device moves an adjustment socket to a position where the adjustment socket is fittable to a head of the cam bolt and moves a tightening socket to a position where the tightening socket is fittable to the locknut. Then, the control device acquires a second two-dimensional position of the cam bolt and the locknut in a second direction based on a second actual image captured by a second camera, and corrects, based on the acquired second two-dimensional position, a position of the adjustment socket relative to the head of the cam bolt and a position of the tightening socket relative to the locknut.

Abstract: A conveyor system that transports a plurality of pallets includes: at least two driving devices that each have an engaging portion to be engaged with the pallet located at an upstream-side end portion in a pallet transport direction and that moves the engaging portion in a state where the engaging portion is engaged with the pallet to thereby simultaneously push the plurality of pallets; and a transport portion on which the plurality of pallets are mounted and that is able to transport the plurality of pallets pushed by the driving devices. The conveyor system is configured to transport the plurality of pallets at a constant speed by engaging the engaging portion of one of the driving devices with the pallet and causing the one of the driving devices to start pushing the plurality of pallets by the time when another one of the driving devices completes pushing the plurality of pallets.

Abstract: A work transfer device is capable of moving a carriage in any direction and easily changes processes even with a simple configuration. The work transfer device includes a frame having a slit in a transfer direction, a ribbon body stored in the frame such that an upper portion is guided by the slit, a carriage coupling part connected to an upper end of the ribbon body and protruding from an upper side of the frame, a driving part feeding power to move the ribbon body in the transfer direction, and a tool carriage, which has a support part supporting a work W and has a coupling part coupled to the carriage coupling part, travelling on the frame.

Abstract: A clamping mechanism includes a pair of contact portions facing each other which is capable of directly contacting a tie rod hexagonal portion, and an open-close drive mechanism that causes the both contact portions to move away from and approach the tie rod hexagonal portion. By appropriately changing the distance between surfaces of the mutually facing pair of contact portions, the tie rod hexagonal portion will be securely clamped by the pair of contact portions, regardless of the size of the diameter of the tie rod. Then, the tie rod hexagonal portion is rotated to adjust the toe angle, by rotating the clamping mechanism via the rotation drive mechanism.
