Description

Technical Field

[0001] The present invention relates to the technical field of bulk material bag transfer, and particularly to a bulk material bag palletizing device. Background Art

[0002] Bulk materials, such as grains, fertilizers, cement, etc., are generally packed in bags for easy transportation. After the production process and before distribution and transportation, bulk materials are generally palletized and temporarily stored for easy loading. Taking grains as an example, after the harvested grains are bagged, the bagged grains need to be palletized and then loaded onto a vehicle.

[0003] In the prior art, when palletizing bulk materials, a conveyor belt is generally used to send the bulk material bags to the palletizing position, and then a forklift is used to lift the material bags. Workers standing at a high position remove the material bags from the forklift and then stack the material bags together. During the palletizing process, since the workers stand on the top of the palletized material bags and there are no protective measures on both sides, there are great safety hazards and a risk of falling and getting injured from a high place.

[0004] Therefore, it is necessary to provide a palletizing device with low safety hazards that can effectively prevent or eliminate the risk of workers getting injured. Summary of the Invention

[0035] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0036] As Figure 1 shown, the present invention provides a bulk material bag palletizing device, including a first support 1, a second support 2 and a palletizing device 3;

[0037] The first support 1 includes a vertical stand 11;

[0038] Combined with Figure 5 shown, the second support 2 includes a hollow frame 21, a partition beam 22 and a lifting drive mechanism 23. The hollow frame 21 is of a rectangular structure and is movably sleeved on the stand 11. The lifting drive mechanism 23 is installed on the first support 11 and is drivingly connected to the hollow frame 21 for driving the hollow frame 21 to lift. In a preferred embodiment of the present application, the lifting drive mechanism 23 includes a winch and a pulling rope. The winch is installed at the top of the stand, the upper end of the pulling rope is connected to the winch, and the lower end of the pulling rope is connected to the hollow frame 21. When the winch works, the pulling rope is retracted or released, so that the hollow frame 21 rises or falls. In order to ensure the stable lifting of the hollow frame, the number of winches is at least two.

[0039] The partition beam 22 is installed inside the hollow frame 21 and is arranged along its length direction. A palletizing area 2a is formed between the partition beam 22 and a side edge of the hollow frame 21. The width of the palletizing area is less than its length to ensure that the material bags in the palletizing area are arranged in a single row.

[0040] As Figure 1 And combined with Figure 2As shown, the palletizing device 3 is installed inside the hollow frame 21, which includes a material bag conveyor 31, a material bag reversing assembly 32, and a palletizing assembly 33. The material bag reversing assembly 32 includes two reversing pushers 321 and a transmission member 322. The transmission member 322 conveys the material bag A along the length direction of the palletizing area 2a. The material bag conveyor 31 is installed at one end of the palletizing area 2a and is used to place the material bag A to be palletized. The transmission member 322 is connected to the material bag conveyor 31. The two reversing pushers 321 are respectively installed on both sides of the palletizing area 2a and are arranged above the transmission member 322. The distance l between the two reversing pushers 321 along the length direction of the palletizing area 2a is greater than the width D of the material bag A and less than the length L of the material bag A. The pushing direction of the reversing pusher 321 is perpendicular to the length direction of the palletizing area 2a, that is, D < l < L. This can ensure that when the two reversing pushers 321 are pushed out simultaneously, the material bag A between the two reversing pushers 321 can be rotated to a placement angle such that the short side direction is consistent with the length direction of the palletizing area 2a, preventing all the material bags A from being placed in the same direction and causing unstable palletizing.

[0041] In a preferred embodiment of the present application, the transmission member 322 includes a plurality of transmission rollers. The plurality of transmission rollers are installed in the palletizing area 2a and are arranged at intervals along the length direction of the palletizing area 2a. All the transmission rollers 2a rotate synchronously. In some other embodiments, the transmission member can also be a conveyor belt. The reversing pusher 321 includes an electric push rod 3211 and a push cylinder 3212. The two electric push rods 3211 are respectively installed on the partition beam 22 and the hollow frame 22. The movable rod of each electric push rod 3211 faces the palletizing area 2a. The push cylinder 3212 is rotatably installed at the end of the movable rod. The rotation axis of the push cylinder 3212 is arranged vertically. The setting of the push cylinder can effectively increase the contact area when pushing the material bag and ensure the smoothness and accuracy of the pushing.

[0042] The palletizing assembly 33 includes a plurality of drive rollers 331 rotatably installed on both sides of the palletizing area and a plurality of swing drive mechanisms 332. The drive rollers 331 are installed at intervals along the length direction of the palletizing area 2a. The drive rollers 331 are arranged in one-to-one correspondence on both sides of the palletizing area 2a. One end of the drive roller 331 is swingably installed on the partition beam 22 or the hollow frame 21 on one side of the palletizing area 2a along the vertical direction. Each drive roller 331 has a horizontal working state and a folded state. The swing drive mechanisms 332 are installed in one-to-one correspondence on the drive rollers 331 and are used to drive the drive rollers 331 to swing between the horizontal working state and the folded state, such as Figure 1 and Figure 2As shown, when the driving roller 331 is in the horizontal working state, it can support the material bag A to ensure the stable placement of the material bag A. For example, Figure 3 As shown, when the driving roller 331 is in the folded state, the gap between the two corresponding driving rollers 331 on both sides becomes larger, and the material bag A falls from the gap between the driving rollers on both sides.

[0043] Specifically, for example, Figure 4 As shown, the driving roller 331 includes a rotating member 3311 and a driving roller body 3312. One end of the rotating member 3311 is vertically rotatably installed on the partition beam 22 or the hollow frame 21. An accommodation groove is formed in the upper part of one end of the rotating member 3311 close to the palletizing area 2a. The driving roller body 3312 is rotatably installed in the accommodation groove. The swing driving mechanism is an electric telescopic hydraulic cylinder, and all the electric telescopic hydraulic cylinders expand and contract synchronously to drive the rotating member 3311 to swing on the corresponding partition beam 22 or the hollow frame 21.

[0044] In order to facilitate the transportation of the material bag A on the ground to the material bag conveyor 31, the palletizing equipment further includes a lifting device 4 and a discharging device 5.

[0045] Among them, for example, Figure 5 As shown, the lifting device 4 includes a lifting mechanism 41 and a material tray 42. The lifting mechanism 41 is installed on the vertical frame 11. For example, Figure 7 As shown, the material tray 42 includes a base 421, a support plate 422, an elastic support member 423, and a plurality of rollers 424. The base 421 is installed on the lifting mechanism 41 and is lifted and lowered under the drive of the lifting mechanism 41. The upper end of the base 421 has an inclined end face 4211. The plurality of rollers 424 are distributed in at least one row on the inclined end face 4211 for guiding the material downward along the inclined end face 4211. The support plate 422 is rotatably installed on the top of the inclined end face 4211. A plurality of avoidance grooves 422a are formed on the support plate 422, and each avoidance groove 422a corresponds to each row of the rollers 424. The elastic support member 423 is installed between the support plate 422 and the base 421 for elastically supporting the support plate 422.

[0046] Among them, a plurality of support columns 4241 are installed on the inclined end face of the base 421. The plurality of support columns 4241 are distributed in at least one row on the inclined end face. The upper end of the support column 4241 is rotatably installed with a roller 424. The rotation axis of the roller 424 is parallel to the inclined end face and perpendicular to the rotation axis of the support plate 422. The elastic support member 423 is two compression springs installed between the inclined end face and the support plate 422. One end of each compression spring is installed on one side of the base 421, and the other end is installed on the corresponding side of the support plate 422.

[0047] Preferably, as Figure 6 shown, the lifting mechanism 41 includes a chain 411, a first driving motor 412, and two sprockets 413. The two sprockets 413 are respectively installed at the upper and lower ends of the vertical frame 11. The chain 411 is sleeved outside the two sprockets 413 and is in driving connection with the sprockets 413. The first driving motor 412 is used to drive the sprockets 413 to rotate. A plurality of mounting positions are evenly spaced along the circumference of the chain 411, and each mounting position is correspondingly installed with a material tray 42. More preferably, a locking ear 425 is formed on the side of the base 421 close to the chain 411, and a locking hole for cooperating with and locking the chain 411 is formed on the locking ear 425. The base 421 is connected to the mounting position of the chain through the locking ear 425.

[0048] As Figure 6 and in combination with Figure 9 shown, the discharging device 5 includes a blocking member 51 and a guiding plate 52. The blocking member 51 is installed on the hollow frame 21 and is located on one side of the top of the base 421 away from the inclined end face 4211. The blocking member 51 is used to push the support plate 422 to rotate towards the side close to the base 421. The guiding plate 52 is inclinedly installed on one side of the blocking member 51 and is used to guide the material bag A unloaded from the material tray 42. The lower end of the guiding plate 52 faces the material bag conveyor 31.

[0049] In order to make more reasonable use of the internal space of the hollow frame 21, as Figure 2 shown, the material belt conveyor 31 includes a straight conveyor belt 311 and a right-angle turning conveyor belt 312. The straight conveyor belt 311 is installed corresponding to the lower end of the guiding plate. One end of the right-angle turning conveyor belt 312 is connected to the straight conveyor belt 311, and the other end is connected to the transmission member 322. The lifting mechanism 41 is arranged on the side of the partition beam away from the stacking area.

[0050] The mutual cooperation and pushing between the blocking member 51 and the support plate 422 are specifically as follows. At both ends of one side of the support plate 422 away from the top of the inclined end face, limiting wheels 426 are respectively rotatably installed. The blocking member 51 includes two vertical bar-shaped members respectively installed on both sides of the support plate 422. The distance between the two bar-shaped members is greater than the width of the base 421 and less than the width of the support plate 422. The bar-shaped members sequentially include an extrusion section 511, a maintaining section 512, and a release section 513 from bottom to top. Taking the distance that the bar-shaped member extends towards the material tray 42 as its thickness, the bar-shaped member satisfies that the thickness of the extrusion section 511 gradually increases from bottom to top, the thickness of the maintaining section 512 remains unchanged, the thickness of the release section 513 gradually decreases from bottom to top, and the projection of the maintaining section 512 in the vertical direction partially coincides with the limiting wheel 426 but does not intersect with the base 421.

[0051] The limiting wheel 426 first abuts against the extrusion section 511. Since the thickness of the extrusion section 511 gradually increases from bottom to top, if the support plate 422 needs to move upward, it will inevitably press down the limiting wheel 426, thereby causing the support plate 422 to rotate towards the base 421. When the avoidance groove 422a on the support plate 422 cooperates with the roller 424, the roller 424 contacts the material bag, and the material bag slides down. At this time, the limiting wheel 426 abuts against the maintaining section 512 of the bar-shaped member. After the material tray 42 finishes discharging the material, the limiting wheel 426 continues to move upward and passes through the release section 513. Since the thickness of the release section 513 gradually decreases from bottom to top, under the elastic force of the spring, the support plate 422 resets.

[0052] In order to more conveniently send the material bag onto the material tray 42, further liberate human labor, and make the workload of the loading and unloading workers less and lighter, the palletizing equipment further includes a guide rail 6 and a feeding device 7.

[0053] Among them, in order to facilitate the installation of the feeding device 7, the first bracket 1 further includes a chassis 12 and a support platform 13. The vertical bracket 11 is installed on the chassis 12. The guide rail 6 is laid on the ground. The chassis 12 is slidably installed on the guide rail 6. The support platform 13 is horizontally installed on the chassis 11 and is arranged close to the guide rail 6.

[0054] The feeding device 7 includes a first conveyor belt 71, a second conveyor belt assembly 72 and a third conveyor belt 73. The first conveyor belt 71 is horizontally installed on the chassis 12. The second conveyor belt assembly 72 includes a support rod 721, a second conveyor belt 722, a connecting member 723 and a moving wheel 724. The support rod 721 is inclined and arranged on one side of the chassis 11, and the upper end of the support rod 721 is hinged to the chassis 11. The connecting member 723 is installed at the lower end of the support rod 721. The moving wheel 724 is installed at one end of the connecting member 723 away from the support rod 721. The moving wheel 724 is placed on the support platform 13. The two ends of the second conveyor belt 722 are respectively installed corresponding to the two ends of the support rod 13; The third conveyor belt 73 is horizontally arranged at the upper end of the second conveyor belt 722. The third conveyor belt 73 is arranged end to end with the second conveyor belt 722, and the third conveyor belt 73 faces the chain 411.

[0055] The moving wheel 724 is placed on the support platform 13. When the chassis 12 moves along the guide rail 6, the arrangement of the moving wheel 724 can effectively prevent the support rod 721 from directly dragging on the support platform 13, and can also facilitate the installation of the second conveyor belt 722.

[0056] Furthermore, the feeding device 7 further includes a telescopic adjustment assembly 74. The telescopic adjustment assembly 74 includes a cross beam 741 and a telescopic mechanism 742. The cross beam 741 is horizontally installed on the side of the chassis 12 close to the second conveyor belt 722. The horizontal height of the cross beam 741 is not less than the height of the lower end of the support rod 721. One end of the telescopic mechanism 742 is installed on the cross beam 741, and the other end is installed on the support rod 721. The telescopic mechanism 742 telescopes to drive the support rod 721 to swing.

[0057] When there are obstacles on the support platform 13, such as bulk materials spilling or other foreign objects falling, it may be difficult for the moving wheel 724 to roll directly or cause damage to foreign objects. At this time, the telescopic mechanism 742 can be contracted to lift the support rod 721 together with the second conveyor belt 722 upward to achieve avoidance.

[0058] Since the first conveyor belt 71 and the second conveyor belt 722 are not on the same horizontal plane, there will be an obvious height difference at the docking place between the second conveyor belt 722 and the first conveyor belt 71, which will cause the material bag to not smoothly reach the second conveyor belt 722 from the first conveyor belt 71. Therefore, a number of guide rollers 725 with gradually increasing diameters are arranged at the front end of the second conveyor belt 722. Under the guiding action of the guide rollers 725, the height difference at the connection is reduced, and a smooth transition between the two conveyor belts is achieved.

[0059] To understand the specific working principle of the embodiments of the present application more accurately, the following describes its working process in detail:

[0060] The overall palletizing work includes a feeding process and a palletizing process. In the feeding process, first, the first bracket 1 is moved to the corresponding area according to the palletizing position of the material bags. The winch is started to make the height of the hollow frame 21 close to the ground. Then, three conveyor belts and the first drive motor 412 are started. Then, the staff sequentially place the material bags A filled with bulk materials at the front end of the first conveyor belt 71. Driven by the first conveyor belt 71, the material bags A move backward and reach the second conveyor belt 722 through the guide roller 725. After the material bags A move to the top along the second conveyor belt 722, they reach the third conveyor belt 73. Since the third conveyor belt 73 is arranged towards the chain 411, the first drive motor 412 drives the sprocket 413 to rotate, and the material tray 42 makes a reciprocating circular motion with the chain 411. The material bags A transported through the third conveyor belt 73 fall on the support plate 422 of the material tray 42. During the upward movement of the material tray 42, the discharging action of the above-mentioned contact process is generated in cooperation with the blocking member 51. The material bags on the material tray 42 smoothly reach the linear conveyor belt 311 of the material bag conveyor 31, and the palletizing work enters the palletizing process;

[0061] The material bags A on the linear conveyor belt 311 reach above the driving roller through the right-angle turning conveyor belt 312. The reversing pusher 321 is preset to perform a pushing action periodically to adjust the placement direction of a row of material bags. The material bags A with the adjusted placement direction continue to move to the driving roller 331. At this time, the driving roller 331 is in a horizontal working state. When a single row of material bags A fills the palletizing area, the swing driving mechanism drives the driving roller 331 to swing downward to a folded state, and the material bags A on the driving roller 331 fall downward to achieve one-layer palletizing. Then, the winch is started to drive the hollow frame 21 to rise a certain height. Since the palletizing device 3 is installed in the hollow frame 21, when the hollow frame 21 rises, it drives the palletizing device 3 to lift and lower, thereby realizing palletizing at different height positions. Repeating the above steps sequentially realizes layer-by-layer palletizing of the material bags, and thus completes the overall palletizing work.

[0062] The palletizing equipment provided by the present application realizes the palletizing work of material bags one layer at a time by the cooperation of the hollow frame and the palletizing device, without the need for personnel to stand on the material bags that have been palletized to a certain height to place the material bags, and there is no risk of personnel falling from a height.

[0063] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
