  • Patent number: 7748514
    Abstract: A conveyance device suitable for an automobile assembling plant has an object loading and unloading conveyance device between a hanging conveyance line, in which a pallet supporting a door is conveyed while being supported by a hanging hanger, and an object loading and unloading position on the floor side. The conveyance device also has a pallet transferring position set above the object loading and unloading position, a horizontal conveyance device, which conveys a pallet between the pallet transferring position and a hanger stop position, and an elevating conveyance device which conveys the pallet vertically between the object loading and unloading position and the pallet transferring position. The elevating conveyance device rotates a plurality of pallet mounting bases in an endless cyclic elevating path while holding these in erect postures, and the pallet mounting bases are arranged at even intervals equal to the distance between the upper and lower positions.

  • Patent number: 7077620
    Abstract: The present invention provides a carrier elevating apparatus suitable for a low floor type conveying apparatus with carriers. A cam rail 36 extends along a horizontal running track, along which a carriage runs. The carriage includes a deck 1, on which an erectable cross-linking mechanism 3 is mounted. The cross-linking mechanism 3 supports and vertically moves a carrier 2A. The cross-linking mechanism 3 includes a link 14a and a link 14b. The link 14a is supported at its lower end pivotably by the deck 1 through a fixed horizontal pivot shaft 16. The links 14a and 14b are connected together at their middle points by a fulcrum shaft 15, which is parallel with the pivot shaft 16. The link 14a is fitted with a driven member 25 between the shafts 15 and 16. An elevator 27 is supported vertically movably by the deck 1. The elevator 27 includes a bearing member 32 fixed to its top and a cam follower 34 supported by its bottom.

  • Patent number: 6978873
    Abstract: An induction line cover includes a cylinder-shaped section into which an induction line can be fitted, plate-shaped sections continuously connected outwardly from a pair of ends created by cutting a slit longitudinally in the cylinder-shaped section at a circumferential position of the cylinder-shaped section, and engaging sections formed adjacent outer faces of the plate-shaped sections and being engageable toward the movement track. A cover joining member for connecting the induction line cover has a receiving section which can receive the engaging sections, and is configured to be accommodated within the extent of the outer diameter of the cylinder-shaped section when the engaging sections are engaged toward the movement track. By this, connection between induction line covers can be performed firmly with stability using the cover joining member, and sufficient clearance can be secured between the cover joining member and a pickup coil.
