Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a machine fitting calibration device. Background Technology

[0002] In the tire manufacturing industry, the rubber mixing process is a core element determining product quality, and automated dispensing of pharmaceutical ingredients plays a crucial role. The introduction of automated dispensing systems significantly reduces manual handling during transport, increases the accuracy of ingredient dispensing, and its high-efficiency conveyor cycle time increases the potential for improved production efficiency. Therefore, automated dispensing is being used more and more widely.

[0003] To ensure the accuracy of medicines, weighing before dispensing is of paramount importance. Current technology requires the use of 1 kg, 5 kg, 10 kg, and 20 kg weights for calibration. The scale body is located below the feeder and in a confined space. Personnel need to hold the weights and weigh the scale body one by one, which carries the risk of head injuries and requires a lot of physical strength. Utility Model Content

[0004] To address the shortcomings of existing technologies, a machine-mounted calibration device is proposed, which solves the problems in the background technology where the space below the weighing body is small, requiring personnel to hold weights to calibrate the weighing body one by one, which carries the risk of head injury and requires a lot of physical strength.

[0005] To achieve the above objectives, the present invention proposes the following technologies: A machine-mounted weighing device includes a rectangular conveying channel and a first conveying roller bed connected to the rectangular conveying channel. The rectangular conveying channel includes a first conveying chain located below a feeder. The first conveying roller bed is used for loading and unloading weight frames so that the weight frames can move onto the rectangular conveying channel via the first conveying roller bed and be conveyed along the rectangular conveying channel to the first conveying chain, thereby calibrating the weighing platform corresponding to the feeder.

[0006] Furthermore, the rectangular conveying channel also includes a second conveying chain arranged parallel to the first conveying chain, and a second conveying roller bed connecting the first conveying chain and the second conveying chain. There are two second conveying roller beds symmetrically arranged about the first conveying chain.

[0007] Furthermore, the second conveyor roller bed is located on the left and right sides of the rectangular conveyor channel, and transverse conveyor chains for connecting the first conveyor chain and the second conveyor roller bed are respectively provided at both ends of the second conveyor roller bed.

[0008] Furthermore, the first conveyor roller bed is arranged perpendicular to the second conveyor chain, one end of the first conveyor roller bed is provided with a transverse conveyor chain that connects to the second conveyor chain, and the other end is provided with a weight frame placement point.

[0009] Furthermore, the first conveyor chain includes conveyor chain units corresponding to the number of feeders. Each conveyor chain unit includes a lifting frame, with connecting chains on both sides of the lifting frame. A weighing platform is provided between the two chains. After the chain drives the weight frame to move above the weighing platform, the lifting frame descends, causing the weight frame to fall onto the weighing platform to achieve calibration.

[0010] Furthermore, a first photoelectric sensor is provided at each end of the second conveyor roller bed. The first photoelectric sensor signal is connected to a first drive mechanism for driving the second conveyor roller bed to run, thereby controlling the start and stop of the second conveyor roller bed according to the position of the weight frame.

[0011] Furthermore, the conveyor chain unit is equipped with a second photoelectric sensor, which is signal-connected to a second drive mechanism for driving the conveyor chain unit to operate, and simultaneously signal-connected to a cylinder for driving the lifting frame to rise and fall.

[0012] Furthermore, the second conveyor roller bed is provided with a plurality of rollers arranged at equal intervals, and the transverse conveyor chain includes two single chains arranged between two adjacent rollers, and the single chains are arranged to be raised and lowered.

[0013] Furthermore, the rectangular conveying channel is also equipped with a tare scale and a calibration scale for weighing the weight frame before and after calibration. The tare scale is located on the upstream side of the first conveying chain, and the calibration scale is located on the downstream side of the first conveying chain.

[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include: By setting up a rectangular conveyor channel and a first conveyor roller bed, a closed-loop conveyor path is constructed. The weight frames can be loaded and unloaded via the first conveyor roller bed and circulate within the channel. The first conveyor chain drives the weight frames to move sequentially to the weighing platform corresponding to each feeder, thereby completing the calibration operation of the weighing platform. This setup eliminates the need for manual handling, fundamentally removing the risk of personnel injury in high-density equipment and greatly improving operational safety. Simultaneously, the rectangular conveyor channel replaces heavy manual labor, reducing labor intensity and significantly improving calibration efficiency. Attached Figure Description

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 4 As shown, a machine-mounted weighing device includes a rectangular conveying channel and a first conveying roller bed 1 connected to the rectangular conveying channel. The rectangular conveying channel includes a first conveying chain 3 located below the feeder 2. The first conveying roller bed 1 is used for loading and unloading the weight frame 4 so that the weight frame 4 can move onto the rectangular conveying channel through the first conveying roller bed 1 and be conveyed along the rectangular conveying channel to the first conveying chain 3, thereby calibrating the weighing platform 5 corresponding to the feeder 2.

[0020] By setting up a rectangular conveyor channel and a first conveyor roller bed 1, a closed-loop conveyor path is constructed. The weight frame 4 can be loaded and unloaded through the first conveyor roller bed 1 and circulate within the channel. The first conveyor chain 3 drives the weight frame 4 to move sequentially to the weighing platform 5 corresponding to each feeder 2, thereby completing the calibration operation of the weighing platform 5. The above setup eliminates the need for manual handling, fundamentally eliminating the risk of personnel injury in high-density equipment and greatly improving operational safety. At the same time, the rectangular conveyor channel replaces heavy manual labor, reducing labor intensity and significantly improving calibration efficiency.

[0021] In the machine fitting calibration device of this embodiment, the rectangular conveying channel further includes a second conveying chain 6 arranged parallel to the first conveying chain 3, and a second conveying roller bed 7 connecting the first conveying chain 3 and the second conveying chain 6. There are two second conveying roller beds 7 symmetrically arranged about the first conveying chain 3.

[0022] The first conveyor chain 3 and the second conveyor chain 6 are connected by the second conveyor roller bed 7 to form a complete rectangular loop. The second conveyor roller beds 7 on both sides are used to realize the transfer of the weight frame 4 between the two long side chains.

[0023] The above layout allows the weight frame 4 to smoothly transition to the conveyor chain on the other side via the second conveyor roller bed 7 after completing the calibration of all weighing platforms 5 on one side, and return to the starting point via the first conveyor roller bed 1. This achieves seamless connection and continuous operation of the calibration process, facilitates automation, and optimizes equipment space utilization and operation flow.

[0024] In the machine fitting calibration device of this embodiment, the second conveying roller bed 7 is located on the left and right sides of the rectangular conveying channel, and the two ends of the second conveying roller bed 7 are respectively provided with transverse conveying chains 8 for connecting the first conveying chain 3 and the second conveying roller bed 7.

[0025] By setting up a transverse conveyor chain 8 to connect the first conveyor chain 3 and the second conveyor chain 6 with the second conveyor roller beds 7 on both sides, it is ensured that the weight frame 4 can be transferred smoothly and accurately between different conveyor sections.

[0026] Specifically, a transverse conveyor chain 8 is also provided at the junction of the first conveyor roller bed 1 and the second conveyor chain 6. The first conveyor roller bed 1 is set perpendicular to the second conveyor chain 6, with one end connected to the second conveyor chain 6 via the transverse conveyor chain 8, and the other end extending to the weight frame placement point 9.

[0027] The transverse conveyor chain 8 plays a crucial "transportation hub" role, ensuring the smoothness and positioning accuracy of the weight frame 4 when switching between longitudinal conveying (second conveyor roller bed, first conveyor roller bed) and transverse transfer (first / second conveyor chain), thereby improving the reliability and ease of maintenance of the system.

[0028] The placement point 9 of the weight box makes it easy for staff to place the weight box 4 at a fixed point for feeding or to retrieve the weight box at a fixed point, thus reducing the workload of the staff.

[0029] In the machine-fitted weighing device of this embodiment, the first conveyor chain 3 includes a conveyor chain unit 10 corresponding to the number of feeders 2. The conveyor chain unit 10 includes a lifting frame 11. The lifting frame 11 is connected to two connecting chains 12 on both sides. A weighing platform 5 is arranged between the two chains 12. After the chain 12 drives the weight frame 4 to move above the weighing platform 5, the lifting frame 11 descends so that the weight frame 4 falls onto the weighing platform 5 to achieve weighing.

[0030] Specifically, multiple conveyor chain units 10 are arranged adjacently and in a straight line. The lifting frame 11 drives the weight frame 4 to move through the chains 12 on both sides and transmits the weight between each conveyor chain unit 10 to achieve transmission.

[0031] The working process is as follows: The chain 12 moves, conveying the weight frame 4 directly above the target weighing platform 5. After the weight frame 4 is in place, the lifting frame 11 descends, and the weight frame 4 smoothly falls onto the weighing platform 5 located in the middle of the conveyor chain unit 10. At this time, weighing calibration can be performed. After calibration, the lifting frame 11 rises, and the chain 12 continues to operate, sending the weight frame 4 away for calibration on the next weighing platform 5.

[0032] When the weight box 4 falls onto the weighing platform 5 and the measured weight is different from the weight after tare, the weighing platform 5 will issue an alarm to remind the staff to intervene manually.

[0033] In the machine fitting calibration device of this embodiment, a first photoelectric sensor is provided at each end of the second conveyor roller bed 7. The first photoelectric sensor signal is connected to a first drive mechanism for driving the second conveyor roller bed 7 to run, and then controls the start and stop of the second conveyor roller bed 7 according to the position of the weight frame 4.

[0034] Specifically, the conveyor chain unit 10 is equipped with a second photoelectric sensor. The second photoelectric sensor is signal-connected to a second drive mechanism for driving the conveyor chain unit 10 to operate, and is also signal-connected to a cylinder 13 for driving the lifting frame 11 to rise and fall.

[0035] This embodiment adds an automatic control system to achieve fully intelligent operation. First photoelectric sensors (not shown in the figure) are installed at both ends of the second conveyor roller bed 7. When the weight frame 4 moves to the end of the second conveyor roller bed 7 and blocks the first photoelectric sensor, the sensor will send a signal to the control system. The control system will then control the first drive mechanism used to drive the second conveyor roller bed 7 to start and stop, thereby realizing the precise positioning and automatic transfer of the weight frame 4 on the roller bed.

[0036] Meanwhile, the second photoelectric sensor installed on the conveyor chain unit 10 not only controls the start and stop of the second drive mechanism to position the weight frame 4, but also controls the lifting and lowering action of the cylinder 13. Furthermore, magnetic switches can be installed on the upper and lower ends of the cylinder 13 to detect the extension and retraction status of the cylinder piston rod, ensuring that the lifting and lowering action is completed before proceeding to the next step. This integrated design is compact and particularly suitable for applications where the space below the feeder is limited. By linking photoelectric sensors with signals from the drive and actuator mechanisms, a complete closed-loop control system is constructed. Through an integrated conveying system and automatic control logic, automatic and cyclic calibration of the weight frame across multiple weighing platforms is achieved, significantly improving the automation level and safety of the weighing operation. The system can sense the position of the weight frame 4 in real time and precisely control its conveying, stopping, and lifting actions, realizing full automation from loading the weight frame 4, cyclic conveying, weighing one platform at a time, to final return to its original position. This not only greatly reduces manual intervention but also ensures the standardization and repeatability of the weighing process, improving the reliability and efficiency of the weighing results.

[0037] In the machine fitting calibration device of this embodiment, the second conveying roller bed 7 is provided with a plurality of rollers arranged at equal intervals, and the transverse conveying chain 8 includes two single chains arranged between two adjacent rollers, and the single chains are arranged to be raised and lowered.

[0038] The transverse conveyor chain 8 can adopt a lifting design. When transverse transfer is required, the transverse conveyor chain 8 can be raised to a position slightly above the roller surface to support the weight frame 4 and complete the transverse transfer. After the transfer is completed, it is lowered below the roller to avoid interfering with the rolling transfer of the roller itself.

[0039] The lifting-type horizontal conveyor chain 8 solves the problem of interference between different conveying components in the same space. It is hidden when not in use and rises when in use, making the equipment layout more reasonable, the operation process smoother, reducing wear between components, and improving the long-term stability of the equipment.

[0040] In the machine-fitted weighing device of this embodiment, the rectangular conveying channel is also provided with a tare scale 14 and a weighing scale 15 for weighing the weight frame 4 before and after weighing. The tare scale 14 is located on the upstream side of the first conveying chain 3, and the weighing scale 15 is located on the downstream side of the first conveying chain 3.

[0041] This embodiment further introduces a weight verification mechanism based on the automated control system to ensure the absolute reliability of the calibration process. The tare scale 14 is located upstream of the first conveyor chain 3, i.e., the weighing platform the weight frame 4 passes through before entering the calibration cycle. Its primary function is to perform the "tare" operation: when the weight frame 4 is first placed on the tare scale 14, the system weighs its total weight. If this weight is within the preset range of empty weight frame weights, the system records this weight as the tare weight and automatically deducts it from all subsequent calibration readings, ensuring that the subsequent weighing platform 5 calibrates the net weight of the pure weights. Secondly, if the weighed weight is significantly greater than the empty frame weight, the tare scale 14 can also be used as the first calibration station.

[0042] The weighing scale 15 is located downstream of the first conveyor chain 3, specifically the last weighing platform that the weight box 4 passes through after completing calibration at all weighing stations and before returning to the starting point. Its function is to perform final verification. After completing one round of calibration, the weight box 4 (containing weights) should maintain its weight. The weighing scale 15 will weigh the total weight again and compare it with the initial weight record. If the weight is within the allowable error range, the calibration is considered successful and valid; if the weight deviation exceeds the threshold (possibly due to missing weights, weighing platform malfunction, etc.), the system will issue an alarm indicating calibration failure, requiring manual intervention to prevent the use of an inaccurate weighing platform in production.

[0043] By setting up a tare scale 14 and a calibration scale 15, this device constructs a complete closed-loop quality control system with self-verification capabilities: the tare scale 14 ensures that the calibration benchmark is the net weight of the weights, eliminating errors caused by weight fluctuations in the weight frame itself, and fundamentally improving the accuracy of the calibration data; the calibration scale 15, as the "final gatekeeper," verifies the overall result of a complete round of calibration operations. It can effectively identify abnormal situations that may occur during the cycle, such as weight loss, weighing platform drift, or mechanical failure, promptly interrupting the process and issuing an alarm, thus avoiding quality risks caused by production under unreliable equipment conditions.

[0044] The above settings not only further reduce labor costs, but also enable the entire calibration process to have self-verification capabilities, greatly improving the intelligence and reliability of the system.
