Description

Technical Field

[0001] This utility model relates to the field of tire production technology, specifically to an automatic rotational positioning and conveying device for tire blanks. Background Technology

[0002] Currently, in tire production, when sending the tire blank to the mold, it is necessary for manual labor to first take the tire blank off the shelf, scan the code for identification, and then move the tire blank into the mold. The whole process is manual, which is labor-intensive and inefficient.

[0003] To meet the demand for shifting from manual to mechanized assembly line production, the factory has added robotic arms to pick up tire blanks and transfer them to molds. However, since the robotic arms can only pick up tire blanks in fixed positions, manual adjustments are still required to position the tire blanks so that the robotic arms can pick them up.

[0004] In addition, since the wall thickness at the tire blank joint is relatively thick, the thicker part needs to correspond to the weaker part in the mold when it is placed into the mold. This is to ensure that the dynamic balance of the produced tire is stable. Since the robot arm can only be responsible for grasping and transporting, the alignment of the tire blank and the mold is still corrected by manual lifting. Therefore, it is necessary to develop a device that can rotate and position the tire blank before the robot arm grasps it. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic rotational positioning and conveying device for tire blanks, which can mechanically rotate the tire blank to a suitable angle, thereby facilitating the alignment of the tire blank with the mold after being grasped by a robotic arm.

[0006] The technical solution of this utility model is: an automatic rotation positioning and conveying device for tire blanks, including a conveyor, the top of the conveyor is provided with a conveying end face, the inlet end of the conveyor located on the conveying end face is provided with a gantry frame, and the outlet end is provided with a rotation positioning mechanism and a stand for mounting a barcode scanner.

[0007] The gantry frame is equipped with a telescopic mechanism that extends toward the rotary positioning mechanism;

[0008] The rotary positioning mechanism includes a pair of symmetrically arranged arc-shaped frames, forming a positioning space for clamping the tire blank between the pair of arc-shaped frames. The arc-shaped frame includes an upper arc-shaped plate and a lower arc-shaped plate arranged in parallel. A set of friction rollers for rolling contact with the outer peripheral surface of the tire blank are rotatably connected between the upper arc-shaped plate and the lower arc-shaped plate. A motor for driving one of the friction rollers to rotate is provided on one of the arc-shaped frames.

[0009] The ends of the pair of arc-shaped frames are respectively rotatably connected to the frame of the conveyor, and the other ends of the pair of arc-shaped frames are respectively provided with connecting rods connected to the telescopic mechanism. One end of the connecting rod is rotatably connected to the arc-shaped frame, and the other end is rotatably connected to the free end of the telescopic mechanism.

[0010] Preferably, the telescopic mechanism is a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod.

[0011] Preferably, the upright frame and the telescopic mechanism are both located on the centerline of the conveying end face, and the pair of arc-shaped frames are arranged symmetrically with the centerline of the conveying end face as the center.

[0012] Preferably, the conveyor is a roller conveyor.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This utility model controls the rotary positioning mechanism through a telescopic mechanism, which can move the tire blank to a position that the robot can grasp. The motor on the rotary positioning mechanism drives the friction roller to drive the tire blank to rotate. The tire blank can be rotated slowly, so that it can scan the barcode and also rotate the tire blank mechanically to rotate the joint to a suitable position, so that it can be grasped by the robot and placed into the mold to correspond to the correct position.

[0015] By using mechanized conveying, positioning, and angle calibration, the system significantly reduces manpower and increases work speed compared to traditional manual handling and calibration methods. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0020] An automatic rotational positioning and conveying device for tire blanks includes a conveyor 6, which is a roller conveyor 6, and the top of the conveyor 6 is provided with a conveying end face.

[0021] The conveyor 6 has a gantry 5 at the inlet end of the conveyor face and a rotary positioning mechanism 2 and a stand 1 for mounting a barcode scanner 13 at the outlet end. The barcode scanner 13 for scanning the tire blank barcode is mounted on the upper end of the stand 1.

[0022] The gantry frame 5 is equipped with a telescopic mechanism 4 extending toward the rotary positioning mechanism 2. The telescopic mechanism 4 is a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod.

[0023] The rotary positioning mechanism 2 includes a pair of symmetrically arranged arc-shaped frames 10, with a positioning space for clamping the tire blank formed between the pair of arc-shaped frames 10.

[0024] The arc frame 10 includes an upper arc plate 7 and a lower arc plate 8 arranged in parallel, and a set of friction rollers 9 for rolling contact with the outer peripheral surface of the tire blank are rotatably connected between the upper arc plate 7 and the lower arc plate 8.

[0025] One of the arc-shaped frames 10 is equipped with a motor 12 that drives one of the friction rollers 9 to rotate. The motor 12 is fixed to the arc-shaped frame 10 by a bracket 11. The motor 12 is a slow-speed motor 12 or a motor 12 with a reducer.

[0026] The ends of a pair of arc-shaped frames 10 are rotatably connected to the frame of the conveyor 6, and the other ends of the pair of arc-shaped frames 10 are respectively provided with connecting rods 3 connected to the telescopic mechanism 4. One end of the connecting rod 3 is rotatably connected to the arc-shaped frame 10, and the other end is rotatably connected to the free end of the telescopic mechanism 4.

[0027] When the telescopic mechanism 4 extends, it drives a pair of arc-shaped frames 10 to rotate and unfold outward; when the telescopic mechanism 4 shortens, it drives a pair of arc-shaped frames 10 to close inward.

[0028] The upright frame 1 and the telescopic mechanism 4 are both located on the center line of the conveying end face, and a pair of arc-shaped frames 10 are arranged symmetrically with the center line of the conveying end face as the center.

[0029] Working principle:

[0030] When the tire blank is conveyed to the conveyor 6, it moves along the conveying end face to the telescopic mechanism 4. When the tire blank enters the positioning space used by the rotary positioning mechanism 2 to hold the tire blank, the conveying stops. Then, the telescopic mechanism 4 is controlled to shorten. The telescopic mechanism 4 pulls the arc-shaped frames 10 on both sides to close in the middle. At this time, the tire blank is in a position that the robot can grasp.

[0031] Then start the motor 12 to drive the friction roller 9 to rotate, and the friction roller 9 will drive the tire blank to rotate. When the barcode scanner 13 recognizes the barcode, stop the motor 12 to rotate, and then extend through the telescopic mechanism 4 to drive the arc frame 10 on both sides to open. At this time, the robot arm can grab the tire blank.

[0032] The rotating positioning mechanism 2 is controlled by the telescopic mechanism 4, which moves the tire blank to a position that the robot arm can grasp. The motor 12 on the rotating positioning mechanism 2 drives the friction roller 9 to drive the tire blank to rotate. This allows the tire blank to rotate slowly, which can both scan the barcode and mechanically rotate the tire blank so that the joint is rotated to a suitable position. This makes it easy for the robot arm to grasp the tire blank and place it into the mold so that it is in the correct position. Through mechanized conveying, position and angle calibration, the robot arm can greatly save manpower and improve the operation speed compared to the traditional manual handling and calibration method.

[0033] In addition, this utility model can also add a control mechanism, which can use a computer as a carrier to control the conveyor 6, telescopic mechanism 4 and motor 12 through software automated programming.

[0034] For example, a position sensor is added to the positioning space of the rotary positioning mechanism 2 to detect the position of the tire blank, to obtain signals for starting and stopping the conveyor 6, and to connect the control mechanism with the mechanical, motor 12, and barcode scanner 13 system for data connection.

[0035] When the position sensor detects the tire blank, it transmits a signal to the control mechanism. The control mechanism then controls the telescopic mechanism 4 to drive the rotary positioning mechanism 2 to correct the position of the tire blank. Finally, the control mechanism controls the motor 12 to drive the tire blank to rotate and scan the code.

[0036] When the tire blank rotates and the barcode scanner 13 successfully scans the code, it transmits the signal to the control mechanism. The control mechanism then controls the motor 12 to stop rotating, so that all the tire blanks that have been scanned can rotate to the same angle. The next step is for the control mechanism to send an instruction to the robot to transfer the tire blank to the mold. This computer control process can use the mechanical automation control computer currently used in the factory.

[0037] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
