Description
Technical Field
The invention belongs to the technical field of tire feeding devices, and particularly relates to a tire carcass composite part nondestructive picking device and method.
Background
The tire body cylinder transfer ring is an important component of a tire building machine, and mainly comprises four components, namely a flaring ring, a left steel wire ring clamping ring, a middle ring and a right steel wire ring clamping ring (as shown in figure 1).
The main function and function of the tyre body cylinder transfer ring are to transfer the tyre body cylinder-shaped composite part which is jointed on the tyre body drum to the forming drum accurately without deformation, so as to complete the tyre body forming process. Because the cylindrical composite part of the tire body is mainly a cylindrical composite part of the tire body (as shown in figure 2) formed by attaching a tire side rubber, an inner lining layer, a tire body wirecord fabric, a steel wire ring apex rubber, a tire shoulder cushion rubber and the like on a tire body drum according to the process sequence, the cylindrical composite part of the tire body can collapse and deform once leaving the tire body drum, and a transfer ring of the tire body drum is required to be used as a transfer device in order to keep better roundness of the cylindrical composite part of the tire body in the transfer process and facilitate the subsequent forming process. The main function and function of the flaring ring are that one end of the tire body cylinder is spread to be cylindrical by using 10 cloth spreading claws around the ring body, so that the tire body cylinder is conveniently sleeved in the forming drum. And 6 clamping jaws are respectively arranged on the left and right bead ring clamping rings in the circumferential direction and are used for circumferentially clamping bead rings of the tire body cylinder. The middle ring is mainly used for clamping the carcass barrel between the left bead ring triangle rubber and the right bead ring triangle rubber.
The part clamped by the middle ring is irregular in shape due to the existence of the shoulder cushion rubber, so that the circumferential uniform clamping of the tire body cylinder can be ensured only by adopting a special mechanism and a special method when the part is clamped, otherwise, the middle part of the tire body cylinder can collapse, once the middle part of the tire body cylinder collapses, the tire body cylinder is clamped in the process of being transferred and sleeved into the forming drum, and the tire body cylinder composite part is directly extruded and scrapped when the middle part collapses. Even if slight collapse occurs, the positioning precision in the transfer process can be greatly influenced, the transfer of the tire body cylinder takes a laser marking as a positioning reference, if the middle part collapses and deforms, the laser positioning precision can be directly influenced, and the tire body cylinder can be directly inclined after the tire blank is formed if the tire body cylinder is inclined, so that the tire quality is seriously influenced.
At present, a common tire body composite member middle pickup device in the industry adopts a magnet adsorption and needling positioning mode (as shown in figure 3) in the middle ring circumferential direction, because the tire body cord fabric of the engineering tire is a steel wire cord fabric, the tire shoulder cushion rubber is very thick (the thickest place is about 27 mm), the tire body cylindrical composite member can be adsorbed by adopting a strong magnet in a mode of adsorbing the steel wire cord fabric, and the needling aims to keep the tire body cylindrical composite member from deforming in the transfer process by penetrating a needle body into the tire shoulder cushion rubber. But this approach does not work well in practical applications. As mentioned above, the shoulder wedge of the engineering tire is thicker and has irregular shape; moreover, the specification of the tire which can be produced by the same engineering tire forming machine is more, the tire manufacturer needs to adapt to the market order condition to change the specification frequently, once the specification is changed, the sizes of the two tire shoulders are changed, so that the adsorption force of the magnet adsorption type pick-up device can be changed along with the specification change of the tire at present; in addition, a needle body is punctured into a tire shoulder wedge to leave a needle hole, and air remained in the tire shoulder wedge can cause potential safety hazards to a finished tire. It is therefore necessary to design a pick-up device that is not damaging to the carcass composite.
