Description

Technical Field

[0001] The invention relates to an automatic ton bag material feeding device which applies the principle of gravity blanking and belongs to the field of intelligent manufacturing and logistics transportation. Background Art

[0002] At present, in production sites that use ton bags of granular materials, such as the communication cable manufacturing industry, the granular materials packaged in ton bags need to be continuously fed to the extruder to coat the liquid plastic melted at high temperature on the surface of the cable.

[0003] The continuous feeding of ton bags poses numerous limitations to material handling, conveying, and feeding, as each bag weighs approximately one ton. Two common feeding methods exist. The first involves hoisting the bag using a truss, allowing the granular material to drop from a drop opening below the bag into a hopper below the bag, from which it then enters the equipment. This method presents a problem: once the material drop begins, it cannot be stopped; the bag's contents will not stop falling until the hopper is completely filled. If a production line changes during feeding and the bag's contents remain unused, the bag's opening must be tied with a rope before the remaining material can be removed. However, manual tying is difficult because the lower drop opening is stretched and taut by the material. It requires multiple personnel, and the remaining material in the hopper is full, making it time-consuming to remove. The second method involves hoisting the ton bag onto a truss next to the hopper. The bag is then untied, a straw inserted into the bag, and a vacuum suction machine continuously draws the pellets from the ground into the hopper. This method of feeding with a vacuum suction machine is not only noisy but also relies on a constant supply of electricity. Furthermore, the position of the suction port must be manually adjusted based on the amount of material remaining in the bag, otherwise the feed may be interrupted.

[0004] In view of this, this patent application is hereby filed. Summary of the Invention

[0024] The present invention will be further described below with reference to the accompanying drawings and examples.

[0025] Example 1, as Figure 1 As shown, in an intelligent manufacturing site using the ton bag material feeding device described in this application, the ton bags and pallets 300 are transported to the feeding platform 200 using a cargo AGV trolley.

[0026] When material is needed, the cargo AGV transports the ton bag and pallet 300 and places them on top of the ton bag feeding device 400. The ton bag feeding device 400 is connected to the production equipment 100 at the bottom of the feeding platform 200 via the feeding platform 200. The tether is manually released, and the granular material in the ton bag falls into the silo by its own gravity.

[0027] When there is residual material in the ton bag during the production change, the material cutting and closing mechanism in the ton bag material feeding device 400 will cut off and close the bag.

[0028] Empty bags or ton bags with residual materials, together with the pallets carrying them, are unloaded from the ton bag material feeding device 400 by the cargo-carrying AGV vehicle for transshipment.

[0029] like Figure 2 and Figure 3 As shown, the ton bag material feeding device 400 includes a hopper bracket a mounted on the feeding platform 200 through a hopper bracket fixing plate f;

[0030] An array of pallet guide blocks d is provided on top of the hopper support a. Each pallet guide block d has an inclined surface inclined toward the inner center. When the cargo-carrying AGV places the pallet h and the tote bag g on top of the hopper support a, the array of pallet guide blocks d simultaneously provides horizontal guidance for the pallet h, thereby aligning the pallet h and the tote bag g on top of the hopper support a, thereby facilitating accurate docking of the tote bag g with the hopper e.

[0031] The bottom of the hopper e is connected to the pouring pipe i, and both are fixedly connected to the hopper bracket a;

[0032] At the top of the hopper e, a closing tie mechanism c and a material cutting mechanism b are arranged in sequence from top to bottom in the vertical direction. The material cutting mechanism b is connected to the feed port at the top of the hopper e.

[0033] A pneumatic vibrator j is provided on the hopper support a. When the ton bag material feeding device 400 completes feeding or changes production and there is still residual material in the ton bag g, the pneumatic vibrator j is powered on and starts to drive the hopper support a to vibrate, thereby causing the residual material scattered in the ton bag g to fall off, be collected and fall into the hopper e.

[0034] like Figure 4 and Figure 5 The closing tie mechanism c shown includes a frame 14 and a lifting cylinder 10 provided on the same side of the hopper support a. The lifting cylinder 10 drives the frame 14 to slide back and forth vertically along the hopper support a.

[0035] A lifting plate 4 extends horizontally from the inside of the frame 14. A set of aperture valves 1 are mounted on the lifting plate 4 via an aperture valve mounting plate 2 and a spacer block 3. The opening and closing states of the aperture valves are regulated by a control assembly (not shown). When the cargo-carrying AGV places the ton bag and pallet 300 on top of the ton bag material feeding device 400, the ton bag g containing the granular material passes downward through the inner diameter of the aperture valve 1.

[0036] The aperture valve 1 is a diaphragm valve with a smooth, unobstructed inner diameter that allows for unrestricted flow of materials. The aperture valve 1 comprises an array of interconnected valve discs that open and close the inner diameter. The aperture valve 1 employed in this application is controlled by a control component. When the control component receives a production change signal, it sends a signal to the aperture valve 1, causing the valve disc of the aperture valve 1 to close, thereby tightening the opening of the ton bag G. Conversely, the control component sends a signal to the aperture valve 1, causing the valve disc of the aperture valve 1 to open, thereby loosening the opening of the ton bag G.

[0037] Furthermore, the side of the frame 14 is engaged with at least one set of guide rails 5 through a plurality of sliders 15, and the guide rails 5 are fixedly mounted on the hopper bracket a;

[0038] The lifting cylinder 10 is installed and fixed along the hopper bracket a through the lifting cylinder mounting base 9. The driving rod of the lifting cylinder 10 is vertically connected to the lifting floating joint 13, and the lifting floating joint 13 is connected to the lifting cylinder connecting block 8 installed on the frame 14; when the lifting cylinder 10 is started, the driving rod extends or retracts to drive the frame 14 to rise and fall vertically along the guide rail 5, thereby driving the aperture valve 1 to rise and fall to adjust its vertical position relative to the ton bag g.

[0039] Furthermore, on one side of the hopper bracket a, two groups of limit blocks 6 are symmetrically fixed along the vertical direction through stop screws 12, and a hydraulic buffer 11 is provided on each group of limit blocks 6. Correspondingly, a stop block 7 is provided on the frame 14, and the stop block 7 is vertically arranged between the hydraulic buffers 11 on the two groups of limit blocks 6.

[0040] When the lifting cylinder 10 drives the aperture valve 1 to lift vertically through the frame 14, the stop block 7 can contact the hydraulic buffers 11 at both ends of the vertical direction and stop at a limit position, thereby limiting the lifting height of the aperture valve 1 to prevent it from colliding with the hopper bracket a and the cutting mechanism b.

[0041] like Figure 6 The cutting mechanism b shown includes a cutting cylinder 21 and a bag-opening docking cylinder 27 provided on the top of the hopper e, and the bag-opening docking cylinder 27 is connected to the inner cavity of the hopper e;

[0042] The driving rod of the cutting cylinder 21 is connected to the cutting plate 26 through the cutting floating joint 24. The cutting plate 26 is radially inserted into the bag mouth docking cylinder 27. The cutting cylinder 21 drives the cutting plate 26 to move back and forth in the horizontal direction through the driving rod to open or close the material channel at the top of the hopper e.

[0043] Furthermore, a flange mounting seat 28 is fixedly mounted on the hopper upper cover 29 at the top of the hopper e, and a bag opening docking cylinder 27 is vertically sleeved on the flange mounting seat 28 and the inner circle of the hopper upper cover 29, and the bag opening docking cylinder 27 is vertically downwardly connected to the inner cavity of the hopper e;

[0044] The cutting cylinder 21 is fixed to one end of a set of connecting shafts 23 through a cutting cylinder mounting base 22, and the other end of the connecting shaft 23 is mounted on a flange mounting base 28 through a fixing base 25, so that the cutting cylinder 21 is indirectly mounted on the hopper cover 29;

[0045] The driving rod of the cutting cylinder 21 is connected to the cutting plate 26 through the cutting floating joint 24. The cutting plate 26 is radially inserted into the bag opening docking cylinder 27 and vertically between the flange mounting seat 28 and the hopper cover 29.

[0046] When the control component receives the signal that the hopper e is full or the production is changed, the control component sends a signal to the shut-off cylinder 21. The shut-off cylinder 21 drives the shut-off plate 26 to move horizontally inward through the driving rod. At this time, the shut-off plate 26 moves along the radial direction of the bag opening docking cylinder 27 and closes the inner circle of the hopper cover 29 (such as the inner circle diameter can be 200mm), thereby closing the material falling channel to control the stop of feeding; conversely, the control component sends a signal to the shut-off cylinder 21, and the shut-off plate 26 moves horizontally outward. The shut-off plate 26 is able to open the feeding channel between the bag opening docking cylinder 27, the flange mounting seat 28 and the hopper cover 29 vertically, and the material is able to fall from the ton bag g and enter the hopper e.

[0047] By using the above-mentioned ton bag material feeding device 400, the present application realizes the following automated and intelligent ton bag material feeding process, such as Figure 7 As shown:

[0048] A steel frame is built vertically above the production equipment 100 as a feeding platform 200. To facilitate transportation and cope with the irregular shape of ton bags, pallets are used as carriers during the transfer of ton bags to facilitate insertion and transportation by manual forklifts and cargo AGV carts.

[0049] When the ton bag g is transported to the hopper support a, the lifting cylinder 10 of the closing tie mechanism c drives the frame 14 to rise vertically along the guide rail 5, thereby driving the open aperture valve 1 to rise above the tie rope of the ton bag g. At this time, the bag mouth of the ton bag g is manually guided into the bag mouth docking cylinder 27 of the cutting mechanism b;

[0050] Then, the control component closes the aperture valve 1 and manually unties the tie rope of the big bag g;

[0051] During feeding, the control component opens the valve plate of the aperture valve 1 to loosen the bag opening of the big bag g, and the material can be continuously fed from the big bag g into the hopper e;

[0052] When the material reaches the upper level switch 31, the control component receives a signal that the hopper e is full, and the control component sends a signal to the shut-off cylinder 21, which drives the shut-off plate 26 to move horizontally inward to close the inner circle of the hopper cover 29, stopping the feeding;

[0053] As the production progresses, the material inside the hopper e continues to drop until it reaches the lower material level switch 32. At this time, the control component receives a signal that the hopper e is empty, and the control component sends a signal to the material shut-off cylinder 21. The material shut-off cylinder 21 drives the cut-off plate 26 to move horizontally outward to open the inner ring of the hopper cover 29, allowing the material to continue to fall from the big bag g into the hopper e.

[0054] The material continues to fall until the material level reaches the upper level switch 31 again. The control component sends a signal to the material cut-off cylinder 21 again, and the material cut-off cylinder 21 drives the cut-off plate 26 to close the inner circle of the hopper cover 29, and the cycle is repeated.

[0055] If a production change is required and there is still residual material in the ton bag g, the control component receives a switching signal, and the control component sends a signal to the material-cutting cylinder 21. The material-cutting cylinder 21 finally drives the shut-off plate 26 to close the inner ring of the hopper cover 29 and stop feeding. At the same time, after receiving the production change signal, the valve plate of the aperture valve 1 is closed to tighten the bag opening of the ton bag g. Then a rope is manually tied above the bag opening docking cylinder 27. After the rope is tied, the valve plate of the aperture valve 1 is opened to loosen the bag opening of the ton bag g. Then the lifting cylinder 10 of the closing tie mechanism c drives the frame 14 to descend vertically along the guide rail 5 to make way for the AGV's transport fork, and then the cargo-carrying AGV trolley inserts and transports the ton bag and pallet 300 out.

[0056] This application realizes a digital material management model through the combined use of a centralized feeding platform and an intelligent ton bag material feeding device, thereby improving production efficiency and saving energy while minimizing the use of manpower.

Any modifications, equivalent variations, and modifications to the shapes, sizes, connection methods, and mounting structures of the components described above, as well as minor adjustments to the positions and structures of the components, made in accordance with the technical essence of the present invention, without departing from the structural content of the present invention, shall remain within the scope of the technical solution of the present invention.
