Description

Technical Field

[0001] The utility model relates to the technical field of tire production, and particularly relates to a tire blank weighing device. Background Art

[0002] During the production process of tires, tire blanks are produced by a forming machine. After the forming machine finishes producing the tire blanks, the tire blanks need to be taken out of the forming machine for the next process. However, for large-sized tires, the weight of a single tire blank can often reach more than 30 kg. In the traditional production process, it is necessary to manually carry the tire blank out of the forming machine, which requires a large amount of labor input. To solve the above problems, a tire unloader is used for the above tire blank handling work in the prior art.

[0003] Currently, after the tire blank is formed and manually repaired, it is necessary to weigh the tire blank to check whether the tire blank meets the specifications. The existing weighing process is to unload the tire blank onto the tire blank scale by a tire unloader for weighing, and then grab the tire blank and unload it onto the tooling cart or the tray on the logistics line. The above operation has a low weighing efficiency and cannot well meet the production requirements. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, a tire blank weighing device is proposed, which solves the problem of low weighing efficiency in the above background art, that is, first unload the tire blank onto the tire blank scale by a tire unloader for weighing, and then grab the tire blank and unload it onto the tooling cart or the tray on the logistics line.

[0005] To achieve the above object, the present utility model proposes the following technical solutions for implementation:

[0006] A tire blank weighing device includes a weighing mechanism and an expansion and contraction mechanism. The weighing mechanism is fixedly installed on the expansion and contraction mechanism. After the expansion and contraction mechanism expands and presses against the tire blank to complete tire unloading, the expansion and contraction mechanism contracts to drive the tire blank to gradually approach the weighing mechanism until it abuts against the weighing mechanism to realize tire blank weighing.

[0007] Further, the expansion and contraction mechanism includes a fixed rod, and the weighing mechanism is fixedly connected to the fixed rod. The fixed rod supports the weighing mechanism to facilitate weighing the tire blank on the weighing mechanism.

[0008] Further, the weighing mechanism includes a bearing plate for bearing the tire blank. A detection component is arranged between the bearing plate and the fixed rod. The bearing plate is arranged along the extending direction of the fixed rod.

[0009] Further, the detection component includes a sensor. The sensor is signal-connected to a display component. The sensor transmits the detection value to the display component according to the pressure-bearing condition of the bearing plate to display the weight of the tire blank.

[0010] Further, the detection component further includes a first mounting plate and a second mounting plate. The first mounting plate is fixedly connected to the fixed rod, the second mounting plate is fixedly connected to the bearing plate, and the sensor is located between the second mounting plate and the bearing plate.

[0011] Further, the expansion and contraction mechanism further includes a fixing plate. The fixed rod is perpendicular to the fixing plate and fixedly connected to the fixing plate. The fixing plate is installed on the robotic arm and drives the transport tire blank through the robotic arm.

[0012] Further, the expansion and contraction mechanism further includes a plurality of support frames slidably connected to the fixing plate. The plurality of support frames are symmetrically distributed about the center of the fixed rod, and the support frames are perpendicular to the fixing plate.

[0013] Further, a roller is provided on a side of the support frame away from the fixed rod. The roller is rotatably connected to the support frame. The roller supports the tire blank and rolls along the inner side of the tire blank to adjust the height of the tire blank.

[0014] Further, the bearing plate and the sensor are respectively arranged horizontally. A side of the bearing plate away from the sensor is convexly arc-shaped, and the arc shape matches the inner shape of the tire blank.

[0015] Compared with the prior art, the comprehensive effects brought by the present utility model include:

[0016] By providing a weighing mechanism and an expansion and contraction mechanism fixedly connected thereto, the expansion and contraction mechanism opens to receive the wound and shaped tire blank, and then contracts to reduce the overall size of the expansion and contraction mechanism, driving the tire blank to gradually descend until it falls onto the weighing mechanism. The weighing structure weighs the tire blank. After weighing, the expansion and contraction mechanism opens again to support the tire blank and transfer the tire blank, combining the tire unloading structure with the tire weighing structure to realize that the tire blank can be directly weighed on the tire unloading structure, which can effectively reduce the time-consuming of single tire production and improve the production efficiency of the tire blank.

[0022] As Figures 1 to 2 shown, a green tire weighing device includes a weighing mechanism and an expansion and contraction mechanism. The weighing mechanism is fixedly installed on the expansion and contraction mechanism. After the expansion and contraction mechanism expands and presses against the green tire to complete tire unloading, the expansion and contraction mechanism contracts to drive the green tire to gradually approach the weighing mechanism until it abuts against the weighing mechanism to achieve weighing of the green tire.

[0023] By providing a weighing mechanism and an expansion and contraction mechanism fixedly connected thereto, the expansion and contraction mechanism expands to receive the wound and shaped green tire, and then contracts to reduce the overall size of the expansion and contraction mechanism, driving the green tire to gradually descend until it falls onto the weighing mechanism, and the weighing structure weighs the green tire. After weighing, the expansion and contraction mechanism expands again to support the green tire and transfer the green tire, combining the tire unloading structure with the green tire weighing structure to enable the green tire to be directly weighed on the tire unloading structure, which can effectively reduce the time-consuming of single-tire production and improve the production efficiency of green tires.

[0024] In the green tire weighing device of this embodiment, the expansion and contraction mechanism includes a fixed rod 1, and the weighing mechanism is fixedly connected to the fixed rod 1. The fixed rod 1 supports the weighing mechanism to facilitate weighing of the green tire on the weighing mechanism.

[0025] Specifically, the fixed rod 1 provides support for the weighing mechanism and the green tire, limits the weighing mechanism, and when the expansion and contraction mechanism contracts, the green tire falls onto the weighing mechanism above the fixed rod 1 for weighing.

[0026] Preferably, the weighing mechanism is located directly above the fixed rod 1 to ensure the support stability of the fixed rod 1 for the weighing structure, thereby improving the weighing accuracy.

[0027] In the tire blank weighing device of this embodiment, the weighing mechanism includes a bearing plate 2 for bearing the tire blank, a detection assembly is arranged between the bearing plate 2 and the fixing rod 1, and the bearing plate 2 is arranged along the extending direction of the fixing rod 1.

[0028] Specifically, the bearing plate 2 is arranged to contact the inner side of the tire blank to receive the tire blank that gradually descends when the expansion and contraction mechanism contracts. The bearing plate 2 has a certain length to adapt to tire blanks of different specifications and ensure the bearing effect and stability.

[0029] Specifically, the distance between the carrying plate 2 and the fixing rod 1 is not greater than the stroke of the expansion and contraction mechanism for opening and contracting, thereby ensuring that the expansion and contraction mechanism can drive the tire blank to fall onto the carrying plate 2 during the expansion and contraction process.

[0030] In the tire blank weighing device of this embodiment, the detection component includes a sensor 3, the sensor 3 signal is connected to the display component, and the sensor 3 transmits the detection value to the display component according to the pressure condition of the bearing plate 2 to display the weight of the tire blank.

[0031] Specifically, the sensor 3 is a pressure sensor, and a calculation module is arranged in the display component, which can convert the pressure applied to the supporting plate 2 by the tire blank detected by the pressure sensor into weight. The display component also includes a display module to display the weight value. The above conversion process and related modules can refer to the existing technology and will not be repeated here.

[0032] Preferably, the detection component has a calibration function to exclude the pressure value caused by the weight of the carrier plate 2 itself, and only detect and display the value change caused by the weight of the embryo, thereby improving the detection accuracy.

[0033] In the tire blank weighing device of this embodiment, the detection component also includes a first mounting plate 4 and a second mounting plate 5, the first mounting plate 4 is fixedly connected to the fixing rod 1, the second mounting plate 5 is fixedly connected to the supporting plate 2, and the sensor 3 is located between the second mounting plate 5 and the supporting plate 2.

[0034] Through the above arrangement, a stable connection between the sensor 3 and the supporting plate 2 and the fixing rod 1 is achieved. Specifically, the first mounting plate 4 and the second mounting plate 5 are respectively in the shape of a rectangular parallelepiped, and the sizes of the surfaces where the two are fitted to each other are the same, thereby providing a stable plane support for the sensor 3 and facilitating accurate readings; the sensor 3 is square, and its upper and lower surfaces are respectively fixedly connected to the supporting plate 2 and the second mounting plate 5.

[0035] Preferably, the support plate 2 and the sensor 3 are respectively arranged horizontally, and the side of the support plate 2 away from the sensor 3 is arranged in a convex arc shape, and the arc shape matches the inner shape of the tire blank. The above arrangement prevents the support plate 2 from squeezing and deforming the tire blank, thereby affecting the quality of the tire blank molding.

[0036] Preferably, an installation groove is formed in the fixing column 1. The installation groove is horizontal, and the first mounting plate 4 is installed in the installation groove, which facilitates the stable connection between the cylindrical fixing column 1 and the first mounting plate 4, further ensures flatness, and avoids the inclination of the sensor 3 affecting the reading.

[0037] In the embryo weighing device of this embodiment, the expansion and contraction mechanism further includes a fixing plate 6. The fixing rod 1 is perpendicular to the fixing plate 6 and fixedly connected to the fixing plate 6. The fixing plate 6 is installed on the robotic arm and drives the transported embryo through the robotic arm.

[0038] Setting the fixing plate 6 facilitates the installation of the fixing rod 1 to provide support for the expansion and contraction mechanism, and at the same time facilitates the connection of the robotic arm to drive the expansion and contraction mechanism to transfer the embryo through the robotic arm.

[0039] In the embryo weighing device of this embodiment, the expansion and contraction mechanism further includes a plurality of support frames 7 slidably connected to the fixing plate 6. The plurality of support frames 7 are symmetrically distributed about the center of the fixing rod 1, and the support frames 7 are perpendicular to the fixing plate 6.

[0040] Specifically, the support frame 7 is set to slide on the surface of the fixing plate 6 to achieve expansion and contraction, so as to open and support the embryo for tire removal, and contract to release the tire or drive the embryo to move down to contact the bearing plate 2 for weighing.

[0041] Preferably, four support frames 7 are provided. The fixing plate 6 is provided with symmetrically distributed slide rails. The support frames 7 are guided and slid through the slide rails to improve stability.

[0042] In the embryo weighing device of this embodiment, a roller 8 is provided on the side of the support frame 7 away from the fixing rod 1. The roller 8 is rotatably connected to the support frame 7. The roller 8 supports the embryo and rolls along the inner side of the embryo to adjust the height of the embryo.

[0043] Specifically, when the support frame 7 contracts, the upper two support frames 7 support the embryo. At the same time, during the telescopic process, the two support frames 7 gradually approach and their heights decrease synchronously. At this time, the roller 8 rolls along the inner side of the embryo to avoid friction with the embryo, affecting the quality of the embryo, and gradually drives the embryo to fall onto the bearing plate 2 to achieve weighing.

[0044] Preferably, the expansion and contraction mechanism in this application adopts a tire remover in the prior art, which includes a driving component to drive the support frame 7 to slide on the fixing plate 6. Its specific structure and principle will not be elaborated here.

[0045] Preferably, the weighing device in the present application is used in conjunction with the embryo clamping ring in the embryo forming process to further improve the degree of automation. After the embryo is wound and formed, the embryo clamping ring drives the embryo to move through the robotic arm and slews it at the set position of the expansion and contraction mechanism, so that the sensor 3 and the embryo are in the same plane, that is, the embryo is driven directly above the sensor 3, thus ensuring the detection accuracy of the sensor 3 and reducing errors. Then the expansion and contraction mechanism opens to unload the embryo from the clamping ring, and then contracts to make the embryo fall onto the sensor 3 and the bearing plate 2 to complete weighing. Finally, the support frame 7 opens again to drive the embryo to move to other workstations after the transport vehicle.
