The invention relates to a tire unloading device for a tire building machine and a method for unloading the same, belonging to the field of rubber machinery.

Background technique

At present, the rubber tires that are matched with various types of carriers are mainly made of a bead by using a molding machine to pass the wire bead, the carcass assembly and the belt tread assembly by pressing and reverse wrapping.

Existing tire building machines generally adopt a two-drum or three-drum mainframe structure, such as preparing a carcass assembly on a carcass drum in a three-drum forming machine, and then transporting the carcass assembly to the forming drum to complete the anti-bun of the green tire. After molding, the prepared green embryo is transferred from the forming drum to the unloading embryo device by the belt transfer ring, and finally the embryo blank is removed from the main body by the unloading embryo device, and the entire fetal embryo manufacturing process is completed.

The following is a patent disclosed in the prior art, the application number is ZL200710016571. 4 , a three-drum forming machine for manufacturing a tire blank and a method thereof, the technical solution of which is to form a carcass drum, a belt drum and a forming drum which constitute a main body. Above the bottom rail of the same horizontal axis. A carcass transfer ring assembly for transporting the prepared carcass assembly to the forming drum is slidably coupled to the bottom rail for transporting the prepared belt-tread assembly to the belt transfer ring of the forming drum. Above the bottom rail. The unloading mechanism that intersects the axial centerline of the main body adopts a suspended embryo transfer method, that is, a guide rail along the top cross member of the unloading mechanism, and the tire is transferred from the belt transfer ring and unloaded to the tire loading trolley.

The problems with the above-described green tire manufacturing equipment and unloading embryo apparatus are:

1. The tire blank is manufactured by the bottom rail for reciprocating transmission, and the tire unloading mechanism adopts the top rail hanging unloading method.

Such cross-aligned equipment installation structure is easy to cause a safety accident caused by collision between personnel and equipment, and also has high requirements for ground leveling and transmission component installation accuracy, and is also disadvantageous for installation and maintenance of the tire discharge mechanism.

2. During the unloading process of the tire loading trolley, a sufficient advance and retreat stroke is required for the tire roller assembly carrying the green tire. This is the original intention of the above-mentioned mainframe and the unloading mechanism to adopt the cross-arrangement installation method, that is, to save the tire unloading The travel distance occupied by the superimposed area is reused by the space occupied by the mechanism. However, this type of structure is limited to the main frame structure for the production of the bottom rail of the green tire. If the production of the green tire is also carried out by the top rail, it is impossible to adopt the cross arrangement of the above-mentioned unloading mechanism and the main body.

In view of this, the patent application is filed.

Summary of the invention The tire forming machine unloading tire device and the method thereof according to the present invention have the purpose of solving the shortcomings of the prior art, and combining the transfer method of the top rail in the manufacture of the green tire, and integrally disposing the unloading embryo device on the host side . In order to meet the advance and retreat stroke required when the tire roller assembly is unloaded, and to save the space occupied by the tire discharge mechanism separately, the horizontal rotation structure and mode from the initial station to the unloading station are adopted to fully utilize the space above the ground.

Another object of the invention is to effectively reduce the installation accuracy of the transmission components between the unloading embryo device and the main machine, and to facilitate installation and overhaul of the unloading mechanism, thereby avoiding safety accidents such as collisions between on-site operators and equipment.

In order to achieve the above object, the tire building machine unloading apparatus has a tire loading cart and a support frame provided with at least one tire loading station. among them,

a carriage is vertically connected to the top cross member of the support frame;

a cantilever is horizontally connected to the carriage, and a tire roller assembly for carrying the green tire is connected at the end of the suspension wall; at the initial station of the unloading embryo device, the central axis of the tire roller assembly and the tire molding machine main body The center axes coincide. The difference from the prior art is:

A more refined and improved structure is that the tire loading trolley can be placed as follows, that is, the axial center line of the tire loading trolley is perpendicular to the axial centerline of the molding machine main body or the tire roller assembly at the initial working position. In order to smoothly and accurately unload the green tire into the tire loading station, the tire roller assembly is pivotally connected to the end of the cantilever, and a second cylinder is connected between the tire roller assembly and the cantilever, and the second cylinder is driven. The tire roller assembly swings horizontally around the end of the cantilever.

Based on the improvement of the overall installation and transfer structure of the above-described unloading embryo device, the present invention also realizes the following method for unloading the embryo: The embryos that have completed the reverse-wrapping molding are unloaded from the forming drum and are transferred axially to the tire roller assembly by the belt transfer ring. The difference from the prior art is that

During the unloading of the green tire to the tire-carrying station of the tire-carrying trolley, the first driving device drives the green tire through the rotating shaft and the cantilever to rotate 180 ° along the horizontal plane.

On the basis of the above method, in the process of unloading the green tire from the belt transfer ring to the tire loading station, the support frame is integrally connected to one side of the gantry of the top of the tire molding machine main body, the support frame and the gantry The frame is at 90 °; the second driving device is driven along the top beam of the support frame, and the tire beam is driven to the vertical direction of the tire-loading station by the transverse beam and the carriage;
