A raising/lowering conveyance device for a container for conveying an article has container supports that can move toward or away from a container in the horizontal direction and up and down with respect to the container. The container supports have a plurality of container support pins that can advance/retreat in the horizontal direction from the container and that are forcibly held at a position protruding from a front surface of the container support. The container supports are configured to lift the container by the container support pins which protrude under a downward step surface formed on the outside of the container. A pin main body of the container support pins protrudes from the front surface and has a flat tip perpendicular to the center axis of the pin main body, and has a tapered shape that increases in diameter toward the flat tip and is thicker toward the end.

Raising/lowering conveyance device for container for conveying article

A raising/lowering conveyance device for a container for conveying an article includes a container gripping mechanism having multiple container support pins which are arranged so as to be capable of freely protruding and retracting. A spring for biasing the container gripping mechanism upward is interposed between the container gripping mechanism and a columnar support member for supporting the container gripping mechanism such that the container gripping mechanism can be freely raised and lowered. As a result of the upward biasing force of the spring, the container gripping mechanism is held at an equilibrium height in equilibrium with the weight thereof and is capable of movement vertically with the equilibrium height serving as the center of the movement. When the container gripping mechanism lifts a container, the mechanism receives the weight of the container, descends from the equilibrium height, and is supported at the fixed height of the columnar support member.

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.

Container raising/lowering conveyance apparatus

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.

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.

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.

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.
