Description

Technical Field

[0001] The invention relates to the technical field of tire production, in particular to a speed regulating device based on pressure as a regulating method. Background Art

[0002] Tires are a general term for tires, which are circular elastic rubber products that are grounded and rolled on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. During the production and processing of tires, the tire half parts need to be transported. At present, roller conveyors are mostly used for the transportation of tire half parts.

[0003] The prior art generally uses a floating stick adjustment method to adjust the front and rear linkage line speeds, and lacks a corresponding detailed rear-stage linkage line speed adjustment scheme. The floating stick often deviates, the equipment failure rate is high, there is no corresponding early warning and error correction method, and the equipment does not have its own regular inspection function. In addition, the prior art solution measures the linkage line or motor speed, which is then represented as the actual speed of the half-component. However, due to the speed loss between the two, the actual half-component speed ≠ the linkage line speed or the motor speed.

The conveyor belt 205 is driven by the fifth motor 2053 to operate when working.

[0040] The operation method of the present invention:

[0041] The half-component speed detected by the front-end speed detector 18 is defined as — V1 half-component;

[0042] The half-component speed detected by the rear-stage speed detector 17 is defined as V2 half-component;

[0043] The set speed of the first motor 12 is defined as - V1 motor;

[0044] The set speed of the second motor 10 is defined as - V2 motor;

[0045] The set speed of the third motor 9 is defined as - V3 motor;

[0046] The set speed of the fourth motor 5 is defined as - V4 motor;

[0047] The half-component runs through the contact sheet 805, pressing the spring 802. The pressing force of the half-component at different speeds is different, and the pressing height of the corresponding telescopic rod 803 is also different, and the pressure measured by the pressure sensor 801 is also different. The front section detection roller 14 is driven by the second motor 10, and the speed matching setting of the first motor 12 and the second motor 10 is the same. The rear section detection roller 16 is driven by the third motor 9, and the speed matching setting of the third motor 9 and the fourth motor 5 is the same, that is, when the speed of the third motor 9 is determined, the speed matching of the fourth motor 5 is the same as that of the third motor 9, thereby achieving a stable state of the linkage line speed. The V1 half-component is measured by the front-end speed detector 18 and displayed on the front-end speed display panel 15. The V2 half-component is measured by the rear-end speed detector 17 and displayed on the rear-end speed display panel 6. Example of setting the preset range of the percentage difference of the front and rear linkage line speed: the percentage difference of the front and rear linkage line speed is 5%, the rear motor speed adjustment and display panel 7 of the third motor 9 is set, the third motor 9 is set, the V3 motor reading is displayed on the rear motor speed adjustment and display panel 7 of the third motor 9, and it drives the rear detection roller 16 of the rear linkage line to move. When the rear speed detector 17 of the rear linkage line measures the actual speed of the V2 half-component on the rear end speed display panel 6 to reach 95% V1, the V3 motor at this time is recorded (due to kinetic energy loss, V3 motor ≠ V2 half-component). That is, the lowest point of the half-component from the height of the telescopic rod height position sensor, the actual speed of the V2 half-component reaches 105% V1, and the V3 motor at this time is recorded (due to kinetic energy loss, V3 motor ≠ V2 half-component). That is, the lowest point of the telescopic rod, so that the preset control range of the telescopic rod height is determined.

[0048] Operation mechanism:

[0049] When the front and rear speed difference percentage exceeds the preset range requirement (at this time, the telescopic rod height operating range is also out of tolerance), the telescopic rod height position sensor gives feedback, and the third motor 9 adjusts the speed so that the telescopic rod height operating range reaches the previous height preset range (the front and rear speed difference percentage preset range can be set, such as the above 5%). The two-color alarm light 19 gives a red alarm and performs speed adjustment.

[0050] The realization of progressive tolerance requirements, that is, the higher requirements of the standard range of the percentage difference of the front and rear linkage line speed can also be achieved

[0051] When the front and rear speed difference percentage is within the preset requirement range, but does not meet the more stringent standard range requirements, the speed measuring instrument measures the speed and feeds it back to the motor, and the motor adjusts the speed to meet the more stringent standard requirement range (the more stringent standard requirement range can be set, for example 1%). The two-color alarm light 19 turns on the yellow light to alarm and the speed is adjusted.

[0052] The front and rear speed difference percentage reaches the more stringent standard range requirements, the two-color warning light 19 green lights pass, and no speed adjustment is performed

[0053] The speed measuring instrument continuously measures the front and rear speed difference in real time and records it, and calculates the percentage of the front and rear speed difference. If the telescopic rod height operating range exceeds the previous height preset range, the feedback method is the telescopic rod height position sensor feedback, because the telescopic rod height position sensor has sensitive feedback and responds quickly, but the accuracy is low. When it exceeds the preset range, it needs to respond quickly. However, when the front and rear speed difference percentage is within the preset requirement range, but does not meet the more stringent standard range requirements, the feedback method is the speed measuring instrument. The speed measuring instrument measures the speed and feeds it back to the motor, and the motor adjusts the speed to meet the more stringent standard requirement range. The feedback adjustment requires calculation, so the response speed is slow, but the accuracy is high.

[0054] The height position of the telescopic rod is detected by the first telescopic rod height position sensor 806, which checks the operating range of the telescopic rod at intervals (the inspection interval can be set). Self-checking is performed to eliminate external forces such as equipment.

[0055] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Although this specification is described in accordance with the implementation modes, not every implementation mode includes only one technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
