Description

Technical Field

[0001] The utility model belongs to the technical field of stacking, and particularly relates to a weighing platform for goods stacking. Background Art

[0002] Application No. 202021529156.6 provides a weighing structure for the load-carrying platform of a stacker. When this device is in use, after receiving a task instruction, the aisle stacker moves to a specified position and stops stably. The telescopic fork system connected to the weighing sensor extends the forks to the bottom of the goods and lifts the goods. At this time, since the forks are in the extended state and the overall forks are in a lever state, one of the two weighing sensors is under positive pressure and the other is under negative pressure, and the weighing sensors do not measure the goods at this time. When the goods are taken out by the forks in the telescopic fork system and returned to the load-carrying platform frame and stop stably, the weight of the telescopic fork system and the goods on the forks is completely applied to the two weighing sensors. By adding and subtracting the weight values measured by the two weighing sensors respectively, the measured value of the goods weight can be obtained. Then, the aisle stacker automatically compares the measured value with its own set parameters. If the measured value is correct, the aisle stacker will operate normally; if the measured value does not match the system parameter value, the aisle stacker will stop running and issue a fault alarm, and subsequent maintenance will be carried out manually.

[0003] However, when the weight of the goods measured by this device does not match, it can only issue a fault alarm to notify the staff to come and operate, so that the staff can remove the overweight goods, which undoubtedly increases the transportation time of the goods; because it takes a certain amount of time to notify the staff to come and operate, and it takes a long time for the staff to unload the goods and readjust the device again. When overweight goods appear, the entire stacking and transportation process needs to stop, and the overweight goods cannot be automatically separated and transported from the normal goods, so the practicability is poor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following combines specific implementation cases and the attached Figures 1 - 3The present utility model will be further described, but the present utility model is not limited to these embodiments. The present utility model provides a technical solution: a weighing platform for stacking goods, including: a mounting frame 1, a conveying mechanism 2 is installed on one side of the mounting frame 1, two weighing sensors 5 are symmetrically installed on the inner wall of the bottom of the mounting frame 1, a telescopic fork system 3 is installed on the top of the two weighing sensors 5. After the telescopic fork system 3 takes out the goods, the fork moves the goods to the top of the telescopic fork system 3, and the weighing sensor 5 measures the goods; two lifting and transferring mechanisms 4 are installed at the bottom of the mounting frame 1, and the two lifting and transferring mechanisms 4 are symmetrically located on the front and rear sides of the telescopic fork system 3. The weighing sensor 5 feeds back the information to an external controller. After receiving the information, the controller controls the lifting and transferring mechanism 4 to work, and the heights at which the goods with qualified weight and unqualified weight are lifted are different;

[0018] The conveying mechanism 2 includes: a conveying outer shell one 21 and a conveying outer shell two 22. The conveying outer shell two 22 is installed on one side of the mounting frame 1, and the conveying outer shell one 21 is installed on the top of the conveying outer shell two 22. The conveying outer shell one 21 and the conveying outer shell two 22 are at different heights. The goods with qualified measurement are transported into the conveying outer shell one 21, and the overweight goods are transported into the conveying outer shell two 22. The overweight goods are moved into the relatively lower conveying outer shell two 22 to reduce the work done by the lifting and transferring mechanism 4 to overcome the gravity of the goods.

[0019] As a preferred solution, furthermore, the lifting and transferring mechanism 4 includes: a hydraulic cylinder 41 and a conveyor belt 42. Two hydraulic cylinders 41 are symmetrically installed at the bottom of the conveyor belt 42, and the bottom of the hydraulic cylinder 41 is installed at the bottom of the mounting frame 1. The two conveyor belts 42 are arranged in parallel on the front and rear sides of the telescopic fork system 3. The conveyor belt 42 is perpendicular to the conveying outer shell one 21 and the conveying outer shell two 22. The initial position of the conveyor belt 42 is below the fork of the telescopic fork system 3 and does not interfere with each other.

[0020] As a preferred solution, furthermore, a plurality of conveying rollers one 6 are rotatably installed at equal intervals inside the conveying outer shell one 21. A plurality of support rods one 8 are installed on the outer walls of both sides of the conveying outer shell one 21. The tops of the plurality of support rods one 8 on the same side are installed with a retaining rod one 9. The two retaining rods one 9 are parallel to each other. The retaining rod one 9 prevents the goods from falling out of the conveying outer shell one 21 during the movement of the goods.

[0021] As a preferred solution, furthermore, a plurality of feeding ports one 10 are opened in the retaining rod one 9 close to one side of the mounting frame 1; each feeding port one 10 corresponds to the goods at one place. When the mounting frame 1 moves to the designated place to stack the goods, the lifting and transferring mechanism 4 is aligned with the feeding port one 10 at that place, and the opening of the feeding port one 10 is larger than the distance between the outermost walls of the two conveyor belts 42.

[0022] As a preferred solution, further, a plurality of second conveying rollers 7 are rotatably connected at equal intervals inside the second conveying housing 22. The conveying direction of the second conveying rollers 7 is opposite to that of the first conveying rollers 6. A plurality of second support rods 11 are installed on both outer side walls of the second conveying housing 22. At the tops of the plurality of second support rods 11 on the same side, a second retaining rod 12 is installed. The two second retaining rods 12 are parallel to each other. The second retaining rod 12 prevents the goods from falling off the second conveying housing 22 during the movement process.

[0023] As a preferred solution, further, a plurality of second feeding ports 13 are formed in the first retaining rod 9 close to the mounting frame 1. The openings of the second feeding ports 13 are equal in size to the openings of the first feeding ports 10. The second feeding ports 13 correspond to the first feeding ports 10 one by one. The second feeding ports 13 and the first feeding ports 10 are arranged in the vertical direction. One end of the conveyor belt 42 close to the conveying mechanism 2 and the first feeding ports 10 and the second feeding ports 13 are located in the same vertical plane.

[0024] As a preferred solution, further, at least two connecting columns 14 are installed at equal intervals between the first conveying housing 21 and the second conveying housing 22. At least two support columns 15 are installed at equal intervals at the bottom of the second conveying housing 22.

[0025] The telescopic fork system, weighing sensor, conveying roller, hydraulic cylinder and conveyor belt in this case are prior arts. The telescopic fork system and the weighing sensor have the same structures and connection manners as those in the cited documents. As long as the telescopic fork system, weighing sensor, conveying roller, hydraulic cylinder and conveyor belt meet the requirements of this case, they are acceptable.

[0026] Working principle: All the electrical components appearing in this application are externally connected to a power supply and a control switch during use. After this utility model is installed, first check the installation and fixation as well as the safety protection of this utility model, and then it can be used. When in use, the mounting frame 1 moves to a designated ground and stops stably. The telescopic fork system 3 controls the forks to extend outwards, extends the forks to the bottom of the goods and lifts the goods. The forks drive the goods to move back, so that the goods move to the center at the top of the telescopic fork system 3 and stop stably. The weighing sensor 5 at the bottom of the telescopic fork system 3 measures the weight of the goods. By adding and subtracting the weight values measured by the two weighing sensors 5 respectively, the measured weight value of the goods can be obtained.

[0027] When the weight of the goods meets the measurement standard, the hydraulic cylinder 41 drives the conveyor belt 42 to rise, so that the two conveyor belts 42 lift the goods. The conveyor belt 42 drives the goods to be lifted until it is flush with the first conveying housing 21 and then stops moving. The conveyor belt 42 drives the goods to move towards the first conveying housing 21. The goods pass through the first feeding port 10, so that the goods move from the top of the conveyor belt 42 to the top of the first conveying roller 6. The goods are transported outwards by the first conveying roller 6. Then the hydraulic cylinder 41 drives the conveyor belt 42 to descend, so that the top of the conveyor belt 42 descends to below the forks of the telescopic fork system 3.

[0028] When the weight of the goods does not meet the measurement standard, the hydraulic cylinder 41 drives the conveyor belt 42 to rise, so that the two conveyor belts 42 lift the goods. The conveyor belt 42 drives the goods to rise until they are flush with the second conveying housing 22 and then stops moving. The conveyor belt 42 drives the goods to move towards the second conveying housing 22. The goods pass through the second feeding port 13, so that the goods move from the top of the conveyor belt 42 to the top of the second conveying roller 7. The second conveying roller 7 transports the goods outwards. The conveying direction of the first conveying roller 6 is opposite to that of the second conveying roller 7, so that the qualified goods and the overweight goods move to different positions. Then, the hydraulic cylinder 41 drives the conveyor belt 42 to descend, so that the top of the conveyor belt 42 descends to below the forks of the telescopic fork system 3.
