Abstract

PURPOSE:To transfer/load tires having different inside diameters consecutively by means of mechanical operation by arranging a pair of locking members in a mobile member so as to be projected downward, enabling them to swing mutually under linearly symmetrical conditions to its center line, and arranging mutually outward facing locking projections on its tips. CONSTITUTION:A board 6 and a member arranged on this board correspond to a mobile member, and are arranged so as to make a pair, and carry out reciprocating motion in the horizontal direction along guide rails 42 and 43. U shape locking pestles 7 and 7 are a locking member, and fix its edge parts onto swing shafts 64 and 64, and pass loosely through windows 621 and 621 of the board 6, and project downward. Locking projections 71 and 71 are formed by being bent outward in the tip parts of the locking pestles 7 and 7. These locking projections 71 and 71 are hooked/locked on the inner peripheral edge lines 81 of a tire T. Furthermore, a support member 4 descends, and the tip of a sensor H senses that it is brought into contact with the upper surface of the tire T, so that pneumatic cylinder piston mechanisms 631 and 631 are operated, and when the swing shafts 64 and 64 are rotated outward, the locking projections 71 and 71 are locked on the inner peripheral edge lines of the tire T.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire transfer device, which is used to transfer tires from one conveyor to another.

0002

2. Description of the Related Art Conventionally, when tires are transferred from one conveyor to another, it has been done manually by an operator.

0003

[Problems to be Solved by the Invention] However, such conventional transfer work has been disadvantageous in that it is difficult to improve work efficiency because it has relied on human labor.

[0004] An object of the present invention is to eliminate such inconveniences.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the inventor conducted intensive research and realized that the inner circumferential edge of a tire is largely curved inward, and completed the present invention.

The structure of the present invention is such that a movable member is installed in a base frame so as to be able to reciprocate vertically and horizontally, and a pair of locking members are attached to the movable member in a swingable manner downwardly. A locking protrusion is provided at the tip of the locking member, and a locking protrusion is installed at the tip of the locking member, and the pair of locking members are provided to be able to swing in line symmetry with respect to their center lines. This is a tire transfer device with protrusions facing outward.

[0007]

[Operation] Since the tire transfer device according to the present invention is constructed as described above, by inserting the pair of locking members into the ring of the tire and swinging each other outward, the locking members can be locked. A locking protrusion locks onto the inner circumferential edge of the tire. In this state, if the movable member is appropriately moved vertically and horizontally, stopped at a predetermined position, and the pair of locking members are swung inwardly, the locking protrusion of the locking member will move against the tire. The tire can be moved to a predetermined position by removing the pair of locking members from the inner peripheral edge of the tire and then pulling out the pair of locking members from within the ring of the tire.

[0008] If the pair of locking members are oscillated by a rack and pinion mechanism, the locking members can be oscillated by a simple mechanism.

Next, H is a height detection sensor, which is installed on the horizontal portion 62 of the substrate 6. This sensor H is for controlling the swinging of the locking rod 7. The protruding length means that when the tip of the locking rod 7 comes into contact with the tire T, the locking protrusion 71 of the locking rod 7 is attached to the inner peripheral edge 8 of the tire T.
This is the distance that can be locked to 1. Therefore, when the support member 4 is lowered and the tip of the sensor H comes into contact with the upper surface of the tire T, the pneumatic cylinder/piston mechanisms 63, 6 are activated.
31 is activated and the swing shafts 64, 64 are rotated outward, the locking protrusions 71, 71 of the locking rods 7, 7 can be locked to the inner peripheral edge of the tire T.

Next, 9 is a nozzle pipe, which is protruded from the horizontal portion 62 of the substrate 6 so as to be rotatable around its axis. This nozzle pipe 9 protrudes downward between the pair of locking rods 7, 7, and is inserted into the inner peripheral edge of the tire T when the locking rods 7, 7 lock the tire T.
