An object of the present invention is to easily regulate mistracking of a belt revolving between multiple pulleys in a conveyor device. Another object of the present invention is to save the space of a mechanism for regulating mistracking in the conveyor device. A non-driving pulley 36 included in the conveyor device has an adjustment collar 40 between a bearing 38 and a shaft 32 of the non-driving pulley 36. The adjustment collar 40 has an adjustment outer surface 44 inclined relative to a reference axis X_(B) of the shaft 32. The adjustment collar 40 rotated relative to the shaft 32 changes the state of inclination of the adjustment outer surface 44 supporting the bearing 38, thereby changing the orientation of the non-driving pulley 36 having the wrapped belt 14.

In a container raising/lowering conveyance apparatus according to the present invention, pairs of secondary movable bases (pair 30a and 30b and pair 31a and 31b) capable of being moved closer to and away from each other in the Y direction are provided to a pair of main movable bases (21 a and 21b) provided so as to be capable of being moved closer to and away from each other in the X direction. Four gripping raising/lowering bodies (45a to 46b) are respectively and separately supported by the four secondary movable bases so as to be capable of being raised and lowered. Vertical rod-shaped main bodies (66), which are supported by the respective main movable bases so as to be capable of being raised and lowered and which are raised and lowered by being driven by raising/lowering drive means, are disposed at intermediate positions between the Y-direction pairs of gripping raising/lowering bodies. Upper end portions of the vertical rod-shaped main bodies (66) and upper end portions of the gripping raising/lowering bodies at both sides of the vertical rod-shaped main bodies (66) in the Y direction are coupled by coupling means (51A and 51B), which allow the gripping raising/lowering bodies to be moved closer to and away from each other in the Y direction.

In a container raising/lowering conveyance apparatus according to the present invention, a supporting structure (a secondary traveling body (3)), which supports four gripping raising/lowering bodies (45a to 46b) such that the gripping raising/lowering bodies are capable of being raised and lowered, has, provided thereto: an X-direction drive means (22) 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 (YL), among the Y-direction center line (YL) and an X-direction center line (XL), passing through a center position (P) of a right-angled parallelogram surrounded by the four gripping raising/lowering bodies and being parallel to respective side edges of said right-angled parallelogram; and a Y-direction drive means (36) by which the four gripping raising/lowering bodies are moved closer to and away from each other synchronously and symmetrically with respect to the X-direction center line (XL). Both the X-direction drive means (22) and the Y-direction drive means (36) are used to enlarge and shrink the right-angled parallelogram surrounded by the four gripping raising/lowering bodies (45a to 46b), without changing the center position (P) and the orientation of the right-angled parallelogram.

A transport conveyor and a transport unit including such a transport conveyor are provided in which the transport conveyor can be made compact in the lateral direction while being compatible with a downstream conveyor whose transport direction is different from that of the transport conveyor. A second transport winding member (9), a first relaying winding member (10), and a second relaying winding member are supported to be swingable about a vertical axis (X1) extending along the vertical direction and located on the other side end portion, along a transport direction, of the transport conveyor (5). An operatively connecting mechanism is provided for causing the second transport winding member (9), the first relaying winding member (10), and the second relaying winding member to swing in an operatively connected manner, to cause the second transport winding member (9) and the second relaying winding member to swing integrally about a vertical axis (X1) and to cause the first relaying winding member (10) to swing about the vertical axis (X1) in the direction in which the second transport winding member (9) and the second relaying winding member swing and by an amount of swing that is greater than the amount of swing of the second transport winding member (9) and the second relaying winding member.

In a container raising/lowering conveyance apparatus according to the present invention, at least two lifting raising/lowering bodies (65A and 65B) corresponding respectively to two parallel side surfaces of an article-conveyance container (C) having a planar shape which is a right-angled parallelogram are supported so as to be capable of being raised and lowered, and capable of being moved closer to and away from each other. Support units (67a) which respectively face the two parallel side surfaces of the container (C) are attached to each of the lifting raising/lowering bodies. In each of the support units (67a), pairs of pin-shaped supporting implements (76a and 76b) which protrude towards the container (C) side at symmetrical positions at both sides of a vertical center line of each of the two parallel side surfaces of the container (C) are arranged and supported at suitable intervals in a vertical direction. Each of the pin-shaped supporting implements 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 (76a) having a narrow interval therebetween and pairs of pin-shaped supporting implements (76b) having a broad interval therebetween are arranged alternately in the vertical direction.

When an external force applied condition is satisfied while the actuation controller is performing a first control for continuously performing a process of providing the electric motor with a command value that depends on an error between an actual rotational speed of the electric motor and a first target rotational speed so as to cause the actual rotational speed to approach the first target rotational speed, then the actuation controller, subsequent to the first control, performs a second control.
