Description

Technical Field

[0001] This utility model belongs to the field of equipment for producing tires with steel wire rings, and specifically relates to a steel wire ring conveying device for a cold bonding machine. Background Technology

[0002] In existing tire manufacturing processes with steel wire rings, the initial bead requires attaching triangular rubber strips around the steel wire ring. If the production quantity of tires in a batch is small, cold bonding is typically used. The existing cold bonding process includes the following steps: the steel wire ring is placed in the center of the forming plate; triangular rubber strips are placed on the forming drum; the forming drum is moved forward; when the forming drum reaches the center of the forming plate, it expands, the triangular rubber strips are flipped up, and their inner diameter is increased, thus fitting around the steel wire ring to form the initial bead; the forming drum returns to its initial position and is removed from the center of the forming plate, completing the initial bead production. The removed initial bead usually needs to be laid flat and stacked to prevent deformation. In the existing cold bonding process, placing the steel wire ring, unloading the initial bead from the forming plate, and stacking the initial bead all require manual labor. To reduce the labor intensity of operators, designing an automated cold bonding machine that automatically places, unloads, and stacks the initial bead has become the goal of technological innovation in this field. To achieve automatic wire ring assembly, the wire rings must be placed one by one into a fixed position (preparatory station) so that the robot arm can repeatedly grab the wire rings at that position and transfer them to the forming plate. Utility Model Content

[0003] The purpose of this utility model is to provide a wire ring conveying device for a cold bonding machine, so as to realize the conveying of stacked wire rings one by one to the preparation station, and solve the technical problem of wire ring conveying and positioning in the design of automatic cold bonding machine.

[0004] The technical solutions for achieving the above objectives include the following:

[0005] A wire ring conveying device for a cold bonding machine includes a base, a vertical sprocket conveyor, a wire ring stacking bin, a horizontal conveying device, and a standby horizontal plate.

[0006] The steel ring stacked bins include left and right conveying bins mounted on a base and spaced apart on the left and right. Two sprocket conveyors, one on the left and one on the right, are symmetrically installed within the left and right conveying bins. Several steel ring support plates are evenly spaced along the vertical direction on the adjacent conveying surfaces of the left and right sprocket conveyors. These steel ring support plates are arranged along the front-to-back direction. Every two steel ring support plates of equal height on the left and right sprocket conveyors form a steel ring bearing platform. Limiting rods are provided at the front end of each of the left and right conveying bins, facing inwards. During operation, the left and right sprocket conveyors move synchronously downwards intermittently.

[0007] The horizontal conveying device includes a horizontal cylinder and a sliding plate driven by the horizontal cylinder. The sliding plate is equipped with a vertical lever. The horizontal cylinder drives the sliding plate to move back and forth. The front stop position of the sliding plate is a preparatory position, and the rear stop position of the sliding plate is below the left and right conveying chambers.

[0008] The standby horizontal plate is set in the preparation position, and the rear part of the standby horizontal plate is provided with a clearance groove along the front-back direction.

[0009] Furthermore, the steel ring stacking chamber also includes a spacing adjustment device mounted on a base. A guide rail is provided on the base along the left-right direction, and the left and right conveying chambers are movably mounted on the guide rails and connected to the spacing adjustment device. Adjusting the spacing between the left and right conveying chambers allows for adjustment of the width of the steel ring carrying platform, thereby enabling the conveying of steel wire rings of different diameters.

[0010] Furthermore, the spacing adjustment device includes a double-ended screw, which is arranged parallel to the guide rail and rotatably mounted on the base. The two ends of the double-ended screw are respectively screwed into the bottom of the left and right conveying chambers. Rotating the double-ended screw can drive the left and right conveying chambers to move on the guide rail, thereby realizing the separation and closing of the left and right conveying chambers.

[0011] Furthermore, the double-headed screw has an adjustment wheel at its center, which can be driven by a power source to rotate the double-headed screw.

[0012] Furthermore, the horizontal cylinder is a rodless cylinder.

[0013] When the above-mentioned wire ring conveying device is in use, wire rings are first filled between the left and right conveying bins behind the wire ring stacking bins, so that each wire ring bearing platform supports one wire ring. The sprocket conveyor moves intermittently downwards in rhythm with the working rhythm of the forming drum. When the lowest wire ring is lower than the top of the lever, the sprocket conveyor stops moving downwards. The horizontal cylinder drives the slide plate forward. After the lever abuts against the inner wall of the wire ring, it moves the wire ring forward. The lever passes through the clearance slot, and the wire ring is supported by the standby horizontal plate and gradually detaches from the wire ring bearing platform. The slide plate stops moving after reaching the front stop point. At this time, the wire ring arrives at the preparatory position and waits for the robot to grab it. After the wire ring is transferred by the robot, the horizontal cylinder drives the slide plate to move backwards. The lever passes through the clearance slot, and the slide plate stops moving after reaching the rear stop point. The sprocket conveyor moves downwards, and the wire ring supported on the wire ring bearing platform moves downwards. When the wire ring is lower than the top of the lever, the sprocket conveyor stops moving downwards, and the horizontal cylinder drives the slide plate forward, thus starting the horizontal conveying of another wire ring.

[0014] The steel wire ring conveying device of this utility model can meet the needs of automatic cold bonding machine, realize the automatic one-by-one conveying of multiple stacked steel rings to the preparation station, so as to facilitate the positioning, gripping and transfer of the robot arm.

[0015] It should be noted that the vertical and horizontal conveying and positioning of the steel wire rings mentioned above require the use of a controller circuit that works in conjunction with other components of the cold bonding machine. Those skilled in the art can design the relevant circuits based on the mechanism operation principle provided in this case, which will not be elaborated here. Attached Figure Description

Two sprocket conveyors 1-1-1 are provided, left and right, and symmetrically installed in the left and right conveying silos 1-2. The adjacent conveying surfaces of the left and right sprocket conveyors 1-1-1 are uniformly arranged along the vertical direction. Several steel ring support plates 1-1-2 are installed at intervals. The steel ring support plates 1-1-2 are arranged in the front-to-back direction. Every two steel ring support plates of equal height on the left and right sprocket conveyors form a steel ring bearing platform. The front end of the left and right conveying bins is provided with a limit rod 1-1-3 facing inward.
