[0002] The tire unloading device of the traditional heavy-duty truck engineering tire shaping and vulcanizing machine is in the form of a robot, which is installed at the rear of the vulcanizer. The robot unloading method is as follows: the robot places the vulcanized tire on the tire rolling device at the rear of the vulcanizer, and slides the tire to the tire conveyor line along its roller device. Due to the heavy weight of heavy-duty truck engineering tires, there is a certain impact force after the tire slides down, which often causes the conveyor line belt or its accessories to be damaged by impact; when the robot grabs, the claw of the robot extends into the gap between the tire bead and the bladder clamp to grab, so the claw is designed to be relatively thin, with a low safety factor and is very easy to damage. At the same time, when the robot is used for a long time, it needs to be adjusted regularly to ensure the accuracy of the robot to prevent the robot from having low stability in tire unloading.

DETAILED DESCRIPTION

[0019] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0020] like Figure 1 and Figure 2 As shown, a fully automatic forward tire unloading device for a heavy truck engineering tire vulcanizer is mainly composed of a tire unloading arm 1, a forward tire unloading disc 2, a tire unloading support frame 3, a moving assembly, a conveying assembly and a supporting assembly. Among them, the tire unloading arm 1 is arranged on the tire unloading support frame 3 through the moving assembly, and is located between the vulcanizer and the forward tire unloading disc 2. The tire unloading arm 1 can move up and down and move parallel to the vulcanizer and the forward tire unloading disc under the action of the moving assembly. In order to realize automatic demoulding, an open groove that can pass through the central axis of the vulcanizer is arranged on the side of the tire unloading arm 1 facing the vulcanizer, and a conveying assembly that can realize the parallel movement of the tire on the tire unloading arm 1 is arranged on the tire unloading arm 1.

[0021] Preferably, the tire unloading arm 1 includes a tire unloading arm bracket, and two tire unloading conveyor lines extending between the vulcanizer and the forward tire unloading disc are arranged on the tire unloading arm bracket at intervals, wherein the transport component is the tire unloading conveyor line, and the tire unloading conveyor line can adopt a roller conveyor line, which can effectively reduce the friction generated when the tire moves.

[0022] The specific structure of the moving assembly includes a lifting assembly and a translation assembly, the translation assembly is arranged on the tire unloading support frame, and the lifting assembly is arranged on the translation assembly. The translation assembly includes a translation motor 5 arranged on the tire unloading support frame 3, a translation screw rod 6 is arranged at the output end of the translation motor 5, and both ends of the translation screw rod 6 are arranged on the tire unloading support frame 3 through corresponding screw rod seats 7, a screw nut 8 is screwed on the translation screw rod 6, a connecting block 9 is arranged on the outer sleeve of the screw nut 8, and a translation block 10 located above the tire unloading support frame 3 is arranged at the upper end of the connecting block 9, that is, the translation assembly is driven by the screw nut, and of course, a linear motor, a telescopic cylinder and other mechanisms can also be used. For the convenience of guiding, a guide rail slider assembly is arranged between the translation block 10 and the tire unloading support frame 3, and of course, the guiding structure can also adopt a guide rod and other mechanisms. For the convenience of confirming the position of the tire unloading arm, a first detection assembly for detecting the distance between the tire unloading arms is arranged on the translation block 10 and the tire unloading support frame 3.

[0023] The lifting assembly specifically includes a lifting cylinder 11 disposed on the translation block 10, and the output shaft of the lifting cylinder 11 is disposed on the bottom surface of the tire unloading arm 1, that is, the lifting is achieved by a telescopic cylinder, and of course, the lifting can also be achieved by a screw nut or a linear motor. For the convenience of guidance, a guide rod 12 for ensuring vertical lifting is provided between the tire unloading arm 1 and the translation block 10, and guidance during lifting can also be achieved by a guide rail slider and other mechanisms.

[0024] The forward tire unloading plate 2 is arranged between the tire unloading arm 1 and the tire conveying line 4 through a support assembly, and is located in the moving direction of the tire conveying line 4. The support assembly can realize the tilting of the forward tire unloading plate 2 toward the moving direction of the tire conveying line 4. The specific structure of the support assembly includes four tilting assemblies distributed in a rectangular shape, and the tilting assembly includes a tilting bracket 13, and a tilting cylinder 14 is hinged on the tilting bracket 13, and the output end of the tilting cylinder 14 is hinged on the forward tire unloading plate 2. When the tilting cylinder on the side facing the tire conveying line 4 is retracted or the tilting cylinder on the side away from the tire conveying line 4 is raised, the forward tire unloading plate 2 can be tilted toward the tire conveying line 4.

[0025] Preferably, at least two blocking frames 15 for preventing the tire from falling are arranged at intervals on the side of the forward tire unloading tray 2 away from the tire conveying line 4. Of course, blocking frames can also be arranged on the four sides of the forward tire unloading tray, front, back, left, and right, and only the blocking frame on the side facing the tire conveying line can allow the tire to pass. In order to facilitate the tire to slide from the forward tire unloading tray to the tire conveying line, a plurality of rollers are hingedly arranged on the forward tire unloading tray, and the rollers can not only realize the forward tire unloading tray to roll in the direction of the tire conveying line, but also realize the tire unloading arm to roll in the direction of the forward tire unloading tray, such as a heavy-duty universal ball. Preferably, the universal balls are arranged in a matrix on the forward tire unloading tray, and the distance between the universal ball matrix and the edge of the forward tire unloading tray is less than the radius of the tire.

[0026] A second detection assembly for detecting whether a tire is located on the forward tire unloading tray 2 is provided on the forward tire unloading tray. The first detection assembly and the second detection assembly have the same structure, both comprising a detection sensor and a detection bracket. The detection sensor is arranged at a corresponding position through a corresponding sensor bracket. To facilitate the detection of the translation block, a detection block for detection by the corresponding detection sensor may also be arranged on the translation block.

[0027] When the device works, it includes the following two steps:

[0028] The first step is demoulding. When the vulcanizer opens the mold, the tire unloading arm moves toward the center axis of the vulcanizer under the action of the moving assembly. At the same time, the center axis drives the tire upward, so that the tire unloading arm moves to the bottom of the tire. Then the tire unloading arm rises, and the center axis and lower ring of the vulcanizer fall (preferably, the upper ring of the vulcanizer also rises at the same time to leave space on the tire unloading arm to drive the tire up), so that the tire falls on the tire unloading arm to achieve demoulding.

[0029] The second step is tire unloading. The tire unloading arm moves toward the forward tire unloading tray. When the tire unloading arm approaches the forward tire unloading tray, the conveying assembly drives the tire on the tire unloading arm to move toward the forward tire unloading tray until all the tires are moved to the forward tire unloading tray. Then, the forward tire unloading tray tilts toward the tire conveying line under the action of the supporting assembly, so that the tire can smoothly enter the tire conveying line. The conveying assembly can start working when the distance between the tire unloading arm and the forward tire unloading tray is less than the radius of the tire, or it can start working after the tire unloading arm contacts the forward tire unloading tray.
