A product storage method is carried out by a product storage system comprising an intermediate storage yard, a product moving means capable of holding a product, of moving vertically, laterally and longitudinally and of placing the product at any place in the intermediate storage yard, a first conveying means for conveying products to the intermediate storage yard, a second conveying means for conveying the products out of the intermediate storage yard, and a control means for controlling the product moving means, the first conveying means and the second conveying means. The control means identifies the type of a product conveyed to the intermediate storage yard by the first conveying means and decides whether or not the product is to be sent to a terminal position, the tire moving means transfers the tire be sent to the terminal position to the second conveying means, the second conveying means carries the same product to the terminal position, and the product moving means carries products other than those to be sent to the terminal position to any places in the intermediate storage yard to store the products in groups of types at the places.

Method of storing products and storage system

A tire uniformity measurement and correction apparatus capable of carrying out measurement and correction of tire uniformity efficiently without causing stagnation of a transfer line due to correction of the tire uniformity is provided. The apparatus comprises right and left transfer conveyors arranged in two parallel files for transferring tires; rim shafts provided at each corresponding middle position of the right and left transfer conveyors for supporting and rotating the tire by upper and lower rims; a rotary drum arranged between the right and left rim shafts capable of moving in a right and left direction to be pressed against the tire supported by one of the rim shafts for detecting load condition while rotating together with the tire; grinder mechanism provided on each of the right and left transfer conveyors at a position opposite to the rotary drum with respect to the transfer conveyor; and control means for controlling uniformity measurement by the rotary drum and uniformity correction by the grinder mechanism so that when the uniformity correction of a tire supported by one of the rim shafts is carried out, the uniformity measurement of another tire supported by another rim shaft is carried out.

Apparatus for measuring and correcting uniformity of tires

An apparatus for winding a narrow belt-shaped member in zigzag around a drum. The apparatus includes a support base, and a reciprocative motion device for reciprocatively moving the support base substantially along an axis of the drum between both ends of a predetermined region to maintain the distance between the drum and the support base at a constant value. The apparatus further includes a rocking base supported by the support base rockably about a rocking axis which is a normal to the outer surface of the drum, a rocking device for rocking the rocking base, and an attaching roller supported on the rocking base rotatably about an axis substantially in parallel with the axis of the drum for urging and attaching the supplied belt-shaped member to the drum after being wound partially around the attaching roller. In winding the belt-shaped member around the drum, the rocking base and the attaching roller are rocked by means of the rocking device to cause the rotating axis of the attaching roller to intersect orthogonally a straight line in parallel with the winding direction of the member.
