[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] Reference Figure 1-5 As shown, a weighing system starting device of a weighing forklift includes a forklift body and a fork frame arranged on the forklift body, and a weighing system capable of weighing by the fork frame, wherein the forklift body is hinged with an outer mast, an inner mast slidably connected to the outer mast, a chain roller rotatably connected to the inner mast, and a forklift chain that passes around the chain roller and is respectively connected to the outer mast and the fork frame at both ends, and the fork frame is slidably connected to the inner mast; and the weighing system includes a weighing sensor capable of detecting the force of the forklift chain acting on the outer mast.

[0027] The forklift body is provided with a lifting drive mechanism for driving the fork frame to lift and lower, a lifting control unit for controlling the lifting drive mechanism, and a lifting operating rod 1 that can be used to control the lifting control unit, wherein the lifting drive mechanism includes a lifting cylinder that can drive the inner mast to slide on the outer mast, and the lifting cylinder can push the inner mast to slide upward on the outer mast through the piston rod, and can drive the forklift chain to pull the fork frame to slide upward on the inner mast by rotating the chain roller connected to the inner mast, so as to lift the items. When working, the staff can manually operate the lifting operating rod 1 and cooperate with the lifting control unit to adjust the working state of the lifting cylinder, wherein the lifting control unit is a multi-way valve 4.

[0028] The lifting operating rod 1 is hingedly connected to one end away from the lifting control unit with a lifting rod 11, and the middle part of the lifting rod 11 is hinged on the forklift body. Pulling the lifting rod 11 and rotating it around the hinge with the forklift body can drive the lifting operating rod 1 to move. The weighing system includes a weighing switch 3. The lifting operating rod 1 is provided with a starting operating member 31 which can start the weighing switch 3 when the fork frame is driven to rise. When the weighing switch 3 is started, the weighing system is turned on; when the lifting operating rod 1 stops or when the fork frame is driven to descend, the starting operating member 31 is separated from the weighing switch 3, and the weighing system is turned off.

[0029] The staff can put the lifting lever 1 in the following three working positions by operating the lifting lever 11. One is to press the lifting lever 11 to pull the lifting lever upward, and the lifting lever then drives the fork frame to rise through the lifting control unit. Another is to lift the lifting lever 11 to drive the lifting lever downward, and the lifting lever then drives the fork frame to descend through the lifting control unit. The last one is that the lifting lever 11 is in a natural state, and the lifting cylinder is also in a non-working state. When the lifting lever 11 is lifted and the lifting lever 11 is in a natural state, the starting operating member 31 is separated from the weighing switch 3, that is, the weighing switch 3 is not triggered, and the weighing system is in a closed state. After pressing the lifting lever 11, the starting operating member 31 on the lifting lever can turn on the weighing switch 3, and the weighing system is in an open state.

[0030] To sum up, when the staff performs weighing operation, they can drive the lifting operating rod 1 to be in the working position of raising the fork frame through the lifting rod 11, and the starting operating member 31 on the lifting operating rod 1 in this position can trigger the weighing switch 3, so that the weighing system is in the on state, so that the staff does not need to manually press the switch button to start the weighing system, and the weighing system can be started when the fork frame lifts the items, so that the handling and weighing of the goods can be completed at the same time, effectively overcoming the shortcomings of the existing weighing operation such as cumbersome operation, low operation continuity and low operation efficiency.

[0031] In addition, it should be noted that the weighing switch 3 can be a mechanical switch or an electronic switch, such as a proximity switch, etc., wherein the start operating member 31 is a carrier that can trigger various switches.

[0032] The forklift body is also provided with a tilting drive mechanism for driving the fork frame to tilt forward or backward, a tilting control unit for controlling the tilting drive mechanism, and a tilting operating rod 2 for controlling the tilting control unit, wherein the tilting drive mechanism includes a tilting cylinder capable of driving the outer mast to rotate around the hinge with the forklift body, and the tilting cylinder can push the outer mast to rotate around the hinge with the forklift body through the piston rod, and the outer mast can realize the tilting control of the fork frame during the rotation process. When working, the staff can manually operate the tilting operating rod 2 and cooperate with the tilting control unit to realize the working state of the tilting cylinder, wherein the lifting control unit is a multi-way valve 4.

[0033] The end of the tilt operating rod 2 away from the tilt control unit is hinged with a tilt pull rod 21, and the middle part of the tilt pull rod 21 is hinged on the forklift body. Pulling the tilt pull rod 21 around the hinge with the forklift body can drive the tilt operating rod 2 to move. The weighing switch 3 is fixedly set on the tilt operating rod 2, and the starting operating member 31 on the lifting operating rod 1 is correspondingly set to the weighing switch 3 on the tilt operating rod 2.

[0034] The staff can put the tilt operating lever 2 in the following three working positions by operating the tilt lever 21. One is to press the tilt lever 21 to pull the tilt operating lever 2 upward, and the tilt operating lever 2 then drives the front end of the fork frame to tilt upward through the tilt control unit. At this time, the weighing switch 3 set on the tilt operating lever 2 can move away from the starting operating member 31, that is, the weighing switch 3 is not triggered, and the weighing system is in the off state;

[0035] Another is that the tilting rod 21 is in a natural state, and the tilting cylinder is also in a non-working state, and the weighing switch 3 arranged on the tilting operating rod 2 can be kept separated from the starting operating member 31, that is, the weighing switch 3 is not triggered, and the weighing system is in a closed state;

[0036] The last method is to lift the tilting rod 21 to drive the tilting operating rod 2 to move downward, and the tilting operating rod 2 then drives the front end of the fork frame to tilt downward through the tilting control unit. In this process, since the lifting operating rod 1 needs to be driven by the lifting rod 11 to move upward so that the starting operating member 31 can trigger the weighing switch 3, when the distance between the starting operating member 31 and the weighing switch 3 remains the same, the tilting operating rod 2 moves downward, which can also make the weighing switch 3 touch the starting operating member 31 to start the weighing system.

[0037] Lifting the tilting rod 21 can realize the downward tilting of the front end of the fork frame, that is, in this operating state, either the fork frame has not yet loaded, and the downward tilting of the front end of the fork frame is to prepare for loading; or the forklift has completed the handling and weighing of the goods and is unloading the goods from the fork frame. At this time, the downward tilting of the front end of the fork frame is to facilitate the separation of the fork frame from the goods. This shows that lifting the tilting rod 21 is not in the weighing state, and the time taken to lift the tilting rod 21 to drive the front end of the fork frame to tilt downward is relatively short. It can be set that the starting operating part 31 needs to continuously trigger the weighing switch for 3S seconds before the weighing system gives a weighing value. If the starting operating part 31 needs to trigger the weighing switch 3 for less than S seconds, the weighing system can immediately stop the weighing program. In this process, it can avoid the weighing system making useless calculations when the tilting rod 21 is lifted to drive the front end of the fork frame to tilt downward, and it can also avoid the fork frame giving an inaccurate value when the goods are lifted for less than S seconds.

[0038] In addition, it should be noted that: in the actual operation process, the operator usually presses the tilting rod 21 and the lifting rod 11 at the same time during the weighing operation to synchronously control the two operating states of the front end of the fork frame to tilt upward and lift upward, so as to prevent the objects from slipping off the fork frame during the lifting process. Tilt the front end of the fork frame upward so that even if the objects slip, they will lean against the forklift mast, which is beneficial to improve the safety of the operation. In this process, since the tilting operating rod 2 and the lifting operating rod 1 move in the same direction at the same time, the weighing switch 3 set on the tilting operating rod 2 and the starting operating member 31 set on the lifting operating rod 1 remain separated, that is, the weighing The weight switch 3 is not triggered and the weighing system is in the off state; when the fork frame remains parallel or the front end is tilted upward, the operator will release the tilting rod 21, and the tilting operating rod 2 will be reset, so that the weighing switch 3 touches the starting operating member 31 to start the weighing system. Therefore, when the tilting rod 21 and the lifting rod 11 are pressed at the same time, the tilting cylinder will drive the front end of the fork frame to tilt upward. In order to avoid the fork frame affecting the weighing accuracy of the weighing system when it is tilted, the weighing system will start the calculation after the operator releases the tilting rod 21, which is beneficial to improve the weighing accuracy of the weighing system. The design is ingenious and reasonable, and can meet the operating habits and weighing accuracy requirements of the operators.

[0039] A weighing method using the weighing system starting device of the weighing forklift, in which the weighing sensor continuously detects the force of the fork frame lifting the object while the fork frame drives the object to rise, and the weighing signal measured by the weighing sensor is collected by the acquisition module to form a set of weighing data, and then the weighing data is analyzed and calculated to calculate the actual weight;

[0040] The weighing data analysis and calculation method is as follows: each time a value is taken, N consecutive original sampling values ​​are taken forward as a queue, and the arithmetic average operation is performed on the queue values, and the highest value in the average dynamic weighing data is taken as the final actual weight value.

[0041] In this precise weighing method, the fork frame can continuously and evenly drive the items to rise, so that the inertia of the items can effectively reduce the influence of various interference factors of the forklift on the weighing accuracy when lifting the items, and by performing arithmetic averaging on the values ​​of each queue, the highest value in each average dynamic weighing data is infinitely close to the true value, so that this precise weighing method effectively improves the accuracy of forklift weighing. Evidence is: in the weighing data curve graph measured during the test, it is found that during the forklift operation, the signal curves of each weighing sensor are very similar. Figure 4 and 5 As shown, by performing a certain averaging algorithm on the dynamic fluctuation stage of the curve, the conclusion is very ideal. The maximum fluctuation range is basically between 5‰-1%, which can fully meet the weighing requirements of heavy goods in logistics and transportation.

[0042] The precise weighing method can realize dynamic weighing in the process of lifting the object, and the value range of the original sampling value can be selected from multiple stages, such as the value range of the original sampling value in the process of weighing the object: including the stage from the fork frame not yet weighing the object to the stage from the fork frame lifting the object off the ground. Or the value range of the original sampling value is the process of continuing to lift the object after it is fully weighed: including the stage from the fork frame lifting the object off the ground and continuing to lift it. Or the value range of the original sampling value is the process of continuously lifting the object for S seconds: including the stage from the fork frame not yet weighing the object to the stage from the fork frame lifting the object off the ground and continuing to lift it, or the stage from the fork frame lifting the object off the ground and continuing to lift it. The value range of the original sampling value in each of the above stages can meet the weighing requirements in the above weighing data analysis and calculation method, and when the value range of the original sampling value is in the process of weighing the object, the value range can complete the value average calculation and value judgment extremely quickly, and almost no delay is felt during use, which has a great advantage over the existing weighing efficiency.

[0043] The weighing data analysis and calculation method is as follows: each time the value is taken, N consecutive original sampling values ​​are taken forward as a queue, and the arithmetic average operation is performed on the queue values, and the results of multiple value taking are recorded as an average dynamic weighing data, wherein the frequency of value taking operation is 1-100 Hz; each time the value is taken, N1 consecutive average dynamic weighing values ​​are taken forward as a queue, and the arithmetic average operation is performed on the queue values, and the results of multiple value taking are recorded as multiple average dynamic weighing data, wherein the frequency of value taking operation is 1-100 Hz; the highest value among the multiple average dynamic weighing data is the final actual weight value.

[0044] The results of multiple value taking can be calculated by secondary value taking or multiple arithmetic average calculation, which is manifested as follows: each time the value is taken, N1 consecutive primary average dynamic weighing values ​​are taken forward as a queue, and the arithmetic average calculation is performed on the queue values, and the secondary value taking result is recorded as the secondary average dynamic weighing data, wherein the final actual weight value is the highest value of the secondary average dynamic weighing data; or, each time the value is taken forward, N1 consecutive primary average dynamic weighing values ​​are taken forward as a queue, and the arithmetic average calculation is performed on the queue values, and the secondary value taking result is recorded as the secondary average dynamic weighing data, and when the value is taken again, N2 consecutive secondary average dynamic weighing values ​​are taken forward as a queue, and the arithmetic average calculation is performed on the queue values, and the thrice value taking results are recorded as the thrice average dynamic weighing data, wherein the final actual weight value is the highest value of the thrice average dynamic weighing data; even when the third average dynamic weighing data still has a large fluctuation range, the fourth average dynamic weighing data can be performed to make the fluctuation range of the final average dynamic weighing data tend to be smooth. The number of values ​​N, N1, and N2 can be the same or different. That is, when N is 10, N1 can be 8 or 10, and N2 can be 10 or 12.

[0045] The purpose of performing multiple averaging operations is to reduce the fluctuation range of the weighing data curve and avoid peaks and troughs in a short period of time, which is beneficial for value judgment. The more times the averaging operation is performed, the smaller the fluctuation range of the weighing data curve is, which is more beneficial for value judgment.

[0046] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
