Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a tire blank delivery and positioning detection device. Background Technology

[0002] Currently, in the vulcanization workshop, the tire blanks are delivered to the vulcanizing machine receiving platform by an automatic tire feeding trolley. The tire blanks are then automatically conveyed on the receiving platform. Photoelectric sensors are installed on the rear side of the receiving platform. When the photoelectric sensors detect the tire blanks, the conveying will automatically stop. Then, the centering device under the receiving platform rises to lift the tire blanks and opens the gripping plates for positioning. Finally, the robotic arm descends to grab the tire.

[0003] After prolonged use, oil stains, dust, and other contaminants can interfere with the normal operation of the photoelectric system, often causing the tire blank to be not delivered to the correct position or to the wrong position. This prevents the centering device from positioning and correcting the tire blank, seriously affecting the coordination accuracy between the robot and the tire blank, and can lead to problems such as tire blank damage and tire blank misalignment.

[0004] Therefore, there is an urgent need to develop a highly stable positioning detection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for detecting the delivery and positioning of embryos.

[0006] The technical solution of this utility model is: a tire blank conveying and positioning detection device, comprising a base, a movable seat, a bracket, a tire stop bar, and a mounting plate. The base is horizontally fixed to the rear end of the conveying platform frame, and a front-to-back guide rail is provided on the base. The movable seat is slidably mounted on the guide rail and is connected to a drive assembly. The bracket is fixed on the movable seat, and the tire stop bar is located on the center plane of the conveying platform and is rotatably mounted on the bracket via a left-to-right rotating shaft. The mounting plate is fixed on the movable seat and located behind the tire stop bar.

[0007] The lower end of the mounting plate is connected to the lower end of the tire stop bar by a tension spring, and the mounting plate is equipped with a detection switch and a lower limit bar corresponding to the tire stop bar on the lower side of the rotating shaft. When the tire stop bar is not in contact with the tire blank, its lower part is in contact with the end of the lower limit bar. When the tire blank touches the tire stop bar, the tire stop bar rotates, its lower part moves away and triggers the detection switch.

[0008] Preferably, the mounting plate is equipped with an upper limit rod corresponding to the tire stop rod on the upper side of the rotating shaft.

[0009] Preferably, both the upper limit rod and the lower limit rod are bolts, both of which penetrate the mounting plate and are threadedly connected to the mounting plate.

[0010] Preferably, the detection switch is a photoelectric switch.

[0011] Preferably, the detection switch is a limit switch. When the tire stop bar is not in contact with the tire blank, its lower part touches the limit switch contact; when the tire blank touches the tire stop bar, the tire stop bar rotates, and its lower part moves away from the limit switch contact.

[0012] Preferably, the drive assembly includes a screw arranged parallel to the guide rail, and the base has upright plates at both the front and rear ends. The screw is threadedly connected to the movable seat, rotatably connected to the two upright plates, and one end of the screw passes through the upright plate and is connected to a driver.

[0013] Preferably, the driver is a motor, and its output shaft and one end of the screw are driven by a belt.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This positioning detection device triggers a detection switch after the tire blank collides with the tire stop bar, making it simpler and more stable than traditional photoelectric detection devices. The drive assembly can move the movable seat back and forth, thereby adjusting the position of the tire stop bar and making the device suitable for tires of different sizes.

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

[0020] Reference Figure 1-2 As shown, a tire blank conveying positioning detection device includes a base 4, a movable seat 6, a bracket 7, a tire stop bar 8, and a mounting plate 10. The base 4 is horizontally fixed to the rear end of the conveying platform frame 1, and the base 4 is provided with front-to-back guide rails 5. The movable seat 6 is slidably mounted on the guide rails 5 and is connected to a drive assembly. The bracket 7 is fixed on the movable seat 6, and the tire stop bar 8 is located on the center surface of the conveying platform and is rotatably mounted on the bracket 7 via a left-to-right rotating shaft 9. The mounting plate 10 is fixed on the movable seat 6 and is located behind the tire stop bar 8.

[0021] The lower end of the mounting plate 10 is connected to the lower end of the tire stop bar 8 via a tension spring 14. The mounting plate 10 is also equipped with a detection switch 13 and a lower limit bar 12 corresponding to the tire stop bar 8 on the lower side of the rotating shaft 9. When the tire stop bar 8 is not in contact with the tire blank, its lower part is in contact with the end of the lower limit bar 12. When the tire blank touches the tire stop bar 8, the tire stop bar 8 rotates, its lower part moves away and triggers the detection switch 13.

[0022] In addition, to prevent the tire stop bar 8 from rotating excessively, the mounting plate 10 is also equipped with an upper limit bar 11 corresponding to the upper side of the tire stop bar 8 on the rotating shaft 9.

[0023] Both the upper limit rod 11 and the lower limit rod 12 are bolts, both of which pass through the mounting plate 10 and are threadedly connected to the mounting plate 10.

[0024] More specifically, in this embodiment, the detection switch 13 is a limit switch. When the tire stop bar 8 is not in contact with the tire blank, its lower part touches the limit switch contact. When the tire blank touches the tire stop bar 8, the tire stop bar 8 rotates, and its lower part moves away from the limit switch contact, triggering the limit switch.

[0025] In operation, the receiving belt 2 conveys the tire blank backward. When the tire blank touches the tire stop bar 8, the tire stop bar 8 rotates, and its lower part moves away from the limit switch contact, triggering the limit switch. After receiving the signal from the limit switch, the machine tool controls the receiving belt 2 to stop running. At this time, the tire blank is directly above the centering device 3. Then, the centering device 3 rises to lift the tire blank and opens its gripper to position it, preparing for the robot arm to grab the tire blank and load it into the cylinder. After the robot arm grabs the tire blank, the tire stop bar 8 returns to its original position under the action of the tension spring 14. Example 2

[0026] The difference between this embodiment and embodiment one is that the detection switch 13 in this embodiment is a photoelectric switch.

[0027] When the tire blank touches the tire stop bar 8, the tire stop bar 8 rotates, its lower part moves away and triggers the photoelectric switch. After the machine receives the signal from the photoelectric switch, it controls the receiving belt 2 to stop running. At this time, the tire blank is directly above the centering device 3. Example 3

[0028] As a preferred embodiment of this utility model, this embodiment designs the driving component based on Embodiment 1, specifically as follows:

[0029] The drive assembly includes a screw 15 arranged parallel to the guide rail 5, and upright plates 16 provided at both the front and rear ends of the base 4. The screw 15 is threadedly connected to the movable seat 6 and rotatably connected to the two upright plates 16. One end of the screw 15 passes through the upright plate 16 and is connected to a driver.

[0030] The driver is a motor, and its output shaft is connected to one end of the screw 15 by a belt drive.

[0031] When other specifications of tires need to be produced, the front and rear positions of the tire stop bar 8 need to be adjusted: start the motor, which drives the screw 15 to rotate through the belt, thereby driving the moving seat 6 to move along the guide rail 5.

[0032] In summary, this positioning detection device triggers the detection switch 13 after the tire blank collides with the tire stop bar 8, which is simpler and more stable than traditional photoelectric detection devices. The drive component can move the movable seat 6 back and forth, thereby adjusting the front and rear position of the tire stop bar 8, making this device applicable to tires of different specifications.

[0033] 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.
