Description

Technical Field

[0001] The present invention belongs to the technical field of weighing equipment, and particularly relates to a multi-specification ton bag packaging device and a weighing method. Background Art

[0002] Ton bags belong to a type of powder packaging bag. With the rise of the dry powder industry market and the new energy market, the demand for mining and powder packaging in mines has also increased. According to different application scenarios of ton bags, the required specifications are also diversified, which is mainly reflected in different bag volumes, resulting in different lengths, widths, heights, and sizes of the bag packages and the cloth bags.

[0003] When traditional ton bag filling and weighing equipment is filling, it is generally fixed on the filling bracket through a hook, and then the filling operation is carried out. At the same time, the loading of the ton bag is measured in real time through the weighing equipment to control the loading weight of the ton bag; however, the existing hooks are generally fixed inside the filling bracket, resulting in the inability of the ton bag filling and weighing equipment to hang different specifications of ton bags, which will reduce the use range of the filling and weighing equipment. At the same time, when the weighing device weighs the ton bag, since the material directly falls into the ton bag during the filling process, the weighing device will be affected by the impact force when the material falls, resulting in a low measurement accuracy of the weighing device and making it inconvenient for manual addition or reduction of the material in the ton bag.

The hanging mechanism is slidably disposed on the first weighing mechanism and is slidably connected to the feeding mechanism. By sliding the position of the hanging mechanism on the first weighing mechanism and the feeding mechanism, the position of the hanging mechanism in the bracket 1 can be adjusted, so that the hanging mechanism can hang different models of bulk bags.

[0090] As Figures 1-18 shown, a multi-specification ton bag weighing device provided by the present invention includes a control device, and also includes a bracket 1, a first weighing mechanism arranged on the bracket 1, a feeding mechanism slidably arranged inside the bracket 1 and connected to the first weighing mechanism, several hanging mechanisms slidably arranged on the first weighing mechanism and slidably connected to the feeding mechanism, and a second weighing mechanism located directly below the feeding mechanism for transporting and secondarily weighing the ton bag; the first weighing mechanism, the hanging mechanism, and the second weighing mechanism are respectively connected to the control device.

[0091] The second weighing mechanism includes a weighing bracket 20 located directly below the feeding mechanism, a moving seat 21 slidably arranged on the weighing bracket 20, a weighing sensor B22 arranged inside the moving seat 21 and connected to the control device, a receiving plate 23 slidably arranged on the moving seat 21 and connected to the weighing sensor B22, and a driving mechanism arranged between the moving seat 21 and the weighing bracket 20 for driving the moving seat 21 to move.

[0092] In Embodiment 7, the weighing bracket 20 is located directly below the mounting bracket 15. The moving seat 21 is slidably arranged on the weighing bracket 20. The weighing sensor B22 is arranged in the moving seat 21 and is connected to the control device. The receiving plate 23 is slidably arranged in the moving seat 21 and is connected to the weighing sensor B22. The driving mechanism is arranged between the moving seat 21 and the weighing bracket 20. Specifically, when the weighing sensor A3 detects that the loading amount of the ton bag reaches the preset value, the cylinder A2 places the loaded ton bag on the receiving plate 23. Under the action of gravity, the receiving plate 23 slides in the moving seat 21 and simultaneously squeezes the weighing sensor B22, enabling the weighing sensor B22 to measure the loading amount of the ton bag. At the same time, the weighing sensor B22 transmits the loading amount result of the ton bag to the control device. The control device compares the loading amount result of the ton bag with the preset value. If the loading amount of the ton bag is less than the preset value, the loading amount of the ton bag is increased manually until the loading amount of the ton bag reaches the preset value. If the loading amount of the ton bag is greater than the preset value, the material in the ton bag is taken out manually until the loading amount of the ton bag reaches the preset value. Then, the control device controls the driving mechanism to operate. The driving mechanism drives the moving seat 21 to slide on the weighing bracket 20, so that the loaded ton bag is moved out of the bracket 1, facilitating the transfer of the ton bag.

[0093] If there is a large error between the measurement results of the weighing sensor A3 and the weighing sensor B22, the measurement result of the weighing sensor B22 shall be taken as the standard, so as to reduce the loading error of the ton bag.

[0094] In the present invention, an installation groove is formed on the moving seat 21. Six weighing sensors B22 are provided. The six weighing sensors B22 are installed in the installation groove and are connected to the control device. The receiving plate 23 is slidably installed in the installation groove and is connected to the weighing sensors B22.

When in use, the control device controls the operation of the motor 27, the motor 27 drives the gear 28 to rotate, so that the gear 28 moves on the rack 25. When the gear 28 moves, the gear 28 pushes the motor 27 to move, the motor 27 drives the motor mounting seat 26 to move, the motor mounting seat 26 drives the moving seat 21 to move on the weighing support 20, and the moving seat 21 drives the ton bag to move through the receiving plate 23, thus facilitating the transfer of the ton bag.

[0100] Embodiment 9.

[0101] As Figures 1-18 shown, a multi - specification ton bag weighing device provided by the present invention includes a control device, and also includes a support 1, a first weighing mechanism arranged on the support 1, a feeding mechanism slidably arranged inside the support 1 and connected to the first weighing mechanism, several hanging mechanisms slidably arranged on the first weighing mechanism and slidably connected to the feeding mechanism, and a second weighing mechanism located directly below the feeding mechanism for transferring and second - weighing the ton bag; the first weighing mechanism, the hanging mechanism and the second weighing mechanism are respectively connected to the control device.

[0103] On both inner walls of the weighing support 20, a guiding groove 29 is respectively provided. On both sides of the moving seat 21, a number of mounting shafts 30 are provided. On the mounting shafts 30, rollers 31 located in the guiding grooves 29 are rotatably arranged.

[0104] In this Embodiment 9, the guiding grooves 29 are arranged on both inner walls of the weighing support 20. Six mounting shafts 30 are respectively and mirror-symmetrically arranged on both sides of the moving seat 21 (as Figure 18 shown). Bearings are provided on the mounting shafts 30. The rollers 31 are rotatably mounted on the bearings. The rollers 31 are located in the guiding grooves 29 and move along the length direction of the guiding grooves 29, so that the friction force when the moving seat 21 moves can be effectively reduced.

[0105] A weighing method for a multi-specification ton bag weighing device includes the following steps:

[0106] S1. The sliding hanging mechanism adjusts the position of the hanging mechanism, hangs the ton bag lifting lugs on the hanging mechanism, and at the same time, the bag clamping mechanism clamps the ton bag feeding port on the feeding mechanism; specifically, four hanging mounting seats 6 are slid simultaneously, so that the hanging mounting seats 6 slide on the ear plates 5 and the mounting frames 15 at the same time. The hanging mounting seats 6 drive the elastic retaining pieces 11, the hooks 12 and the cylinder B13 to move synchronously, so as to adjust the position of the hooks 12, place the ton bag lifting lugs on the hooks 12, the control device controls the operation of the cylinder B13, and the cylinder B13 drives the hooks 12 to rotate, so that the hooks 12 cooperate with the elastic retaining pieces 11, thereby fixing the ton bag lifting lugs between the hooks 12 and the elastic retaining pieces 11. At the same time, the discharge pipe 16 is placed into the ton bag feeding port, and the control device controls the operation of the cylinder C19. The cylinder C19 drives the two bag clamping plates 18 to close, so as to clamp the ton bag feeding port and fix it on the discharge pipe 16, thus completing the hanging of the ton bag.

[0107] S2. Start the first weighing mechanism. The first weighing mechanism drives the feeding mechanism and the hanging mechanism to move upward simultaneously, so that the ton bag is suspended; specifically, the control device controls the operation of the cylinder A2. The cylinder A2 drives the ear plate 5 to move through the connecting seat 4. The ear plate 5 drives the hanging mounting seats 6 and the mounting frames 15 to move synchronously at the same time. The mounting frame 15 drives the discharge pipe 16 to move, and the hose 17 contracts. The hanging mounting seats 6 drive the elastic retaining pieces 11, the hooks 12 and the cylinder B13 to move at the same time. The hooks 12 drive the ton bag to move, so that the ton bag is separated from the ground, and the value of the weighing sensor A3 is cleared.

[0108] S3. The control device controls the discharging of the material bin. The material enters the ton bag through the feeding mechanism. At the same time, the first weighing mechanism detects the loading amount of the ton bag in real time until the loading amount of the ton bag reaches the preset value. Specifically, the control device controls the discharging of the material bin. The material in the material bin sequentially enters the ton bag through the feeding pipe 14, the hose 17, and the discharging pipe 16. At the same time, the weighing sensor A3 measures the loading amount of the ton bag in real time and transmits the measurement result to the control device. When the measurement result of the ton bag reaches the preset value, the control device controls the material bin to stop discharging.

[0109] S4. Start the first weighing mechanism. The first weighing mechanism drives the feeding mechanism and the hanging mechanism to move downward simultaneously to place the ton bag on the second weighing mechanism and separate the ton bag from the hanging mechanism. Specifically, the control device controls the operation of the cylinder A2. The cylinder A2 drives the weighing sensor A3 to move downward. The weighing sensor A3 moves downward through the ear plate 5. The ear plate 5 drives the hanging mounting seat 6 and the mounting frame 15 to move synchronously at the same time. The mounting frame 15 drives the discharging pipe 16 to move. The hanging mounting seat 6 drives the elastic retaining piece 11, the hook 12, and the cylinder B13 to move synchronously, so as to place the ton bag on the receiving plate 23. Then the control device controls the operation of the cylinder C19. The cylinder C19 drives the two bag clamping plates 18 to open, so that the feeding port of the ton bag is separated from the discharging pipe 16. The control device controls the operation of the cylinder B13. The cylinder B13 drives the hook 12 to rotate, so that the hook 12 is separated from the elastic retaining piece 11, thereby separating the ton bag from the hook 12.

[0110] S5. The second weighing mechanism measures the loading amount of the ton bag for the second time. If the measurement result reaches the preset value, the second weighing mechanism transfers the ton bag outside the bracket. Specifically, after the ton bag is filled with materials, the ton bag is located on the receiving plate 23. Under the action of gravity, the receiving plate 23 presses the weighing sensor B22, so that the weighing sensor B22 detects the gravity on the receiving plate 23 and transmits the detection result to the control device. The control device compares the detection result of the weighing sensor B22 with the preset value. When the detection result of the weighing sensor B22 reaches the preset value, the control device controls the operation of the motor 27. The motor 27 drives the gear 28 to rotate, so that the gear 28 moves on the rack 25. When the gear 28 moves, the gear 28 pushes the motor 27 to move. The motor 27 drives the motor mounting seat 26 to move. The motor mounting seat 26 drives the moving seat 21 to move on the weighing bracket 20. The moving seat 21 drives the ton bag to move through the receiving plate 23.

[0111] The cylinder A2, weighing sensor A3, cylinder B13, cylinder C19, weighing sensor B22, motor 27, material bin, dust removal equipment and control device used in the present invention are all existing designs and can be directly purchased and used on the market. Therefore, the structures, circuits and principles of the cylinder A2, weighing sensor A3, cylinder B13, cylinder C19, weighing sensor B22, motor 27, material bin, dust removal equipment and control device will not be elaborated here.
