Abstract: A container raising/lowering conveyance apparatus has a supporting structure (a secondary traveling body) which supports four gripping raising/lowering bodies capable of being raised and lowered, and has an X-direction drive means by which the four gripping raising/lowering bodies are moved closer to and away from each other synchronously and symmetrically with respect to a Y-direction center line and a Y-direction drive means by which the four gripping raising/lowering bodies are moved closer to and away from each other synchronously and symmetrically with respect to an X-direction center line. Both the X-direction drive means and the Y-direction drive means are used to enlarge and shrink a right-angled parallelogram surrounded by the four gripping raising/lowering bodies, without changing the center position and the orientation of the right-angled parallelogram.

Abstract: A container raising/lowering conveyance apparatus is provided with: rod-shaped gripping raising/lowering bodies which are long in a raising/lowering direction, and which are supported so as to be capable of being horizontally fitted to and detached from corners of a container; and lifting raising/lowering bodies in which supporting implements protruding towards two parallel side surfaces of the container are provided to rod-shaped main bodies which are long in the raising/lowering direction and are capable of being moved closer to and away from the two parallel side surfaces of the container. When the supporting implements are moved closer to the two parallel side surfaces of the container, the supporting implements are inserted underneath a flange portion at the two parallel side surfaces of the container, and when the rod-shaped main bodies are raised, the supporting implements lift the container via the flange portion.

Abstract: A container raising/lowering conveyance apparatus including four gripping raising/lowering bodies capable of being respectively horizontally fitted to and detached from four corners of an article-conveyance container is configured such that, in a planar view, central raising/lowering link members capable of being raised and lowered are disposed at central positions of respective edges of a right-angled parallelogram surrounded by the four gripping raising/lowering bodies, and each of the central raising/lowering link members and the gripping raising/lowering bodies at both sides thereof are coupled to each other by at least one pair of upper and lower rocking parallel links capable of rocking in the vertical direction.

Abstract: A container raising/lowering conveyance apparatus has a pair of main movable bases relatively movable in the X direction, and on each main movable base, a pair of secondary movable bases relatively movable in the Y direction. Four gripping raising/lowering bodies are supported by the four secondary movable bases so as to be capable of being raised and lowered. Vertical rod-shaped main bodies supported by the main movable bases are raised and lowered by a raising/lowering drive and are disposed at intermediate positions between the Y-direction pairs of the gripping raising/lowering bodies. Upper end portions of the vertical rod-shaped main bodies and gripping raising/lowering bodies at both sides of the vertical rod-shaped main bodies in the Y direction are coupled, allowing the gripping raising/lowering bodies to be relatively movable in the Y direction.

Abstract: A container raising/lowering conveyance apparatus has at least two lifting raising/lowering bodies corresponding respectively to two parallel side surfaces of an article-conveyance container are capable of being raised and lowered, and moved closer to and away from each other. Support units are attached to each of the lifting raising/lowering bodies and pairs of pin-shaped supporting implements in the support units protrude towards the container side at symmetrical positions at both sides of a vertical center line of each of the two parallel side surfaces of the container are arranged and supported at suitable intervals in a vertical direction. Each pin-shaped supporting implement is capable of extending and retracting, and is impelled into and held in a protruded position by a spring. Pairs of pin-shaped supporting implements having a narrow interval therebetween and pairs of pin-shaped supporting implements having a broad interval therebetween are arranged alternately in the vertical direction.

Abstract: A conveying device has interlockingly coupled, rectilinear screw shafts which are driven by a motor. The screw shafts are juxtaposed to an inclined rectilinear portion of a gradient portion in a traveling route of a conveying traveling body and to at least fixed regions adjacent to the gradient portion of respective upper and lower horizontal route portions connected to respective ends of the gradient portion. The conveying traveling body has a pair of front and rear driven rollers engaging with the screw shafts, and an interval between the pair of front and rear driven rollers is set to a length not shorter than a rectilinear distance between end portions of the screw shafts positioned at respective sides of each of arcuate portions at respective upper and lower ends of the gradient portion to make the conveying traveling body travel continuously between the respective upper and lower horizontal route portions.

Abstract: A suspension conveying device according to the present invention includes screw shafts of two suspension line pulling-up/feeding mechanisms in a conveying traveling body 1. The screw shafts have low-speed drive regions, in which feed pitches for driven bodies are small, and high-speed drive regions, in which feed pitches for the driven bodies are large. The screw shafts are installed so that the low-speed drive regions and the high-speed drive regions are disposed mutually oppositely as viewed from the driven bodies when a conveyed object supporter is at one end of an elevation/lowering stroke, and the conveyed object supporter is tilted in a middle of the elevation/lowering stroke when the screw shafts are driven to undergo forward/reverse rotation at a fixed speed by a motor.
