Description

Technical Field

[0001] This invention relates to the field of cigarette box loading and unloading technology, and more specifically, to a cigarette box loading and unloading equipment with a position adjustment function. Background Technology

[0002] During the transportation and loading / unloading of cigarette boxes, various types of trucks, including box trucks and lorries, are used. These box trucks have different widths and lengths. Initially, manual loading, unloading, and stacking of the cigarette boxes is required during transport from the cigarette factory to the truck, or during unloading from the truck bed. This is time-consuming and labor-intensive. If mechanical stacking is used, the following problems arise: While a conveyor belt can transport cigarette boxes into the truck bed, it cannot stack them, especially for truck beds with varying widths and heights. If a traditional robotic arm is used for stacking, it is limited by the side and top walls of the truck bed, preventing stacking at the corners and top, resulting in empty spaces within the truck bed. Furthermore, positional and tilting angle deviations between the vehicle's parking position and the cigarette box conveying mechanism also contribute to stacking difficulties.

[0003] In summary, the current smoke box conveying device has the following shortcomings:

[0004] First, the current cigarette box conveying device cannot automatically load, stack, and unload cigarette boxes during loading and unloading. Manual stacking and manual handling of the stacked cigarette boxes in the car body to the surface of the conveyor belt are still required.

[0005] Secondly, current cigarette box conveying devices mostly use lever-type feeder belts to convey cigarette boxes, which cannot accurately align with the height of stacked cigarette boxes. Furthermore, lever-type feeder belts can only convey cigarette boxes and cannot stack them.

[0006] Third, the current smoke box conveying device is unable to stack cars of different widths and heights in a gradual, orderly and precise manner;

[0007] Fourth, the current cigarette box conveying device can only load and unload goods from the first car body at a specific location, and cannot load and unload goods from the second car body at a non-specific location, resulting in low loading and unloading efficiency.

[0008] Therefore, how to provide a cigarette box loading and unloading equipment with position adjustment function has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0051] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0052] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0053] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0054] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0055] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0056] according to Figures 1 to 9 As shown, the present invention provides a cigarette box loading and unloading device with a position adjustment function, comprising:

[0057] The equipment base plate 1 has universal casters 13 located below it.

[0058] The position adjustment mechanism 2 includes a moving table 21, which is located above the equipment base plate 1 and can move horizontally along the length of the equipment base plate 1.

[0059] The main lifting push rod 3 is fixed on the moving table 21, and the top of the main lifting push rod 3 is equipped with an indexing motor 15;

[0060] The horizontal rotating slot frame 4 is mounted on the indexing motor 15. The main lifting push rod 3 can adjust the height of the horizontal rotating slot frame 4, and the indexing motor 15 can drive the horizontal rotating slot frame 4 to rotate.

[0061] The main conveying mechanism 5 is embedded in the horizontal rotating slot 4, and the conveying direction of the main conveying mechanism 5 is consistent with the length direction of the horizontal rotating slot 4.

[0062] Before using the cigarette box loading and unloading equipment of the present invention, the equipment base plate 1 is moved to the car door and the front side wall of the equipment base plate 1 is aligned with the car door. Then the main conveying mechanism 5 is rotated to a position of exactly 90 degrees to the horizontal direction of the equipment base plate 1 through the horizontal rotating trough 4, so that the axial line of the main conveying mechanism 5 is perpendicular to the front and rear axial lines of the equipment base plate 1. At this time, the axial line of the main conveying mechanism 5 is parallel to the front and rear axial lines of the car, and the main conveying mechanism 5 can be moved to the inside of the car through the horizontal rotating trough 4.

[0063] During loading, the cigarette boxes are transferred from the ground or a manually accessible location to the main conveyor mechanism 5. The main conveyor mechanism 5 then transfers the cigarette boxes from the door of the carriage to the inside of the carriage. As the number of cigarette boxes stacked in the carriage gradually increases, the main conveyor mechanism 5 moves gradually from the inside of the carriage to the outside of the carriage along the horizontal rotating rack 4. During unloading, as the number of cigarette boxes stacked in the carriage gradually decreases, the main conveyor mechanism 5 moves gradually from the outside of the carriage to the inside of the carriage.

[0064] At the same time, the main lifting push rod 3 pushes the horizontal rotating trough frame 4 and the main conveying mechanism 5 to lift and lower. When the cigarette box at the bottom of the car needs to be loaded and unloaded, the main lifting push rod 3 pushes the horizontal rotating trough frame 4 and the main conveying mechanism 5 to the height at the bottom of the car. When the cigarette box at the top of the car needs to be loaded and unloaded, the main lifting push rod 3 pushes the horizontal rotating trough frame 4 and the main conveying mechanism 5 to the height at the top of the car.

[0065] In addition, since the width of the carriage is five times the width of the cigarette boxes, five cigarette boxes can be placed in the width direction of the carriage at the same time. When the main conveying mechanism 5 conveys the cigarette boxes, the position adjustment mechanism 2 can drive the main conveying mechanism 5 to move in the width direction of the carriage in sequence through the main lifting push rod 3 and the horizontal rotating slot frame 4, so that the cigarette boxes are gradually arranged in the width direction of the carriage until the cigarette boxes are filled in the width direction of the carriage, without wasting the carriage space.

[0066] When the equipment is not in use or needs to be moved, the horizontal rotating rack 4 can be rotated to drive the main conveying mechanism 5 to rotate to a position parallel to the equipment base plate 1. At this time, the main conveying mechanism 5 is located directly above the auxiliary conveying mechanism 6.

[0067] In addition, the main conveying mechanism 5 can also rotate negative 90 degrees horizontally through the horizontal rotating trough frame 4. At this time, the axial line of the main conveying mechanism 5 is also perpendicular to the axial line of the equipment base plate 1. Then the rear side wall of the equipment base plate 1 can be connected to the door of another car. Then, by repeating the above-mentioned work process, loading and unloading operations can be performed on another car. Therefore, loading and unloading of two or more cars can be performed with little or no movement, which greatly improves work efficiency.

[0068] Furthermore, the main conveying mechanism 5 includes a rectangular frame 51, a main drive motor 57, and a friction belt 56. The horizontal rotating slot frame 4 has inwardly bent openings on both sides to form inner slots, which are movably fitted into the two outer sides of the rectangular frame 51.

[0069] The rectangular frame 51 is provided with a belt drive shaft 52 rotatably connected at one end near the horizontal rotating slot frame 4, and a tilting shaft 53 rotatably connected at the other end. Multiple drive pulleys 54 are fixedly connected to the belt drive shaft 52, and multiple driven pulleys 55 are rotatably connected to the tilting shaft 53 through bearings. The friction belt 56 is respectively sleeved on the corresponding drive pulleys 54 and driven pulleys 55.

[0070] The main drive motor 57 is fixed to the outer wall of the rectangular frame 51 and is connected to the belt drive shaft 52 for transmission.

[0071] As described above, when the main drive motor 57 rotates, it drives the four drive pulleys 54 to rotate via the belt drive shaft 52. The four drive pulleys 54 drive the driven pulleys 55 to rotate together via the friction belt 56, thus transferring the cigarette box from the front end of the rectangular frame 51 to the rear end for loading, or transferring the cigarette box from the rear end of the rectangular frame 51 to the front end for unloading. During this process, the flip shaft 53 is used as a fixed shaft and does not rotate.

[0072] Furthermore, multiple flip arms 58 are fixedly connected to the flip shaft 53. The flip arms 58 are staggered with the driven pulleys 55. A flip motor 59 connected to the flip shaft 53 is provided on one side of the rectangular frame 51. The flip motor 59 drives the flip shaft 53 and the flip arms 58 to rotate, so as to push the cigarette box on the friction belt 56 out of the rectangular frame 51.

[0073] like Figure 8 As shown, during loading, when the cigarette box is conveyed from the front end to the rear end of the rectangular frame 51, due to the functional limitation of the friction belt 56, the rear side of the bottom of the currently conveyed cigarette box can only rest on the front side of the top of the stacked cigarette boxes and cannot continue to move forward. At this time, the flip motor 59 can be turned forward, and the flip motor 59 drives the three flip arms 58 to rotate positive 90 degrees through the flip shaft 53, pushing the cigarette box that cannot be positioned to the top of the stack. Then, the flip motor 59 is turned in reverse, driving the three flip arms 58 to rotate negative 90 degrees, so that the three flip arms 58 are below the horizontal plane of the friction belt 56. In this way, the cigarette box can continue to be conveyed from the front end to the rear end of the rectangular frame 51.

[0074] During unloading, a mechanism, such as a vacuum suction cup, is installed at the top of the three tilting arms 58 to grip the outer shell of the cigarette box. This grips the side wall of the cigarette box, and then the tilting motor 59 reverses to drive the three tilting arms 58 to rotate negative 90 degrees, pulling the cigarette box out of the stack onto the friction belt 56. The cigarette box is then conveyed from the rear end of the rectangular frame 51 to the front end along the friction belt 56, that is, from the inside of the carriage to the door of the carriage.

[0075] Furthermore, a front and rear motor 42 is provided on one side of the horizontal rotating slot frame 4. The output shaft of the front and rear motor 42 extends into the inner slot and is fixedly connected to a drive gear 43. A transmission rack 510 is fixedly connected to one bottom surface of the rectangular frame 51. The drive gear 43 and the transmission rack 510 mesh with each other so that the rectangular frame 51 can be moved along the length direction of the horizontal rotating slot frame 4 by the front and rear motors 42.

[0076] When the main conveying mechanism 5 needs to move back and forth within the horizontal rotating trough 4, the front and rear motors 42 can be started. The front and rear motors 42 drive the rectangular frame 51 to move along the inner side of the horizontal rotating trough 4 through the meshing of the drive gear 43 and the transmission rack 510. When loading, the cigarette box is gradually moved from the inner end of the carriage to the outer end of the carriage, and when unloading, it is gradually moved from the outer end of the carriage to the inner end of the carriage.

[0077] Furthermore, an auxiliary conveying mechanism 6 is provided on one side of the horizontal rotating trough frame 4. The auxiliary conveying mechanism 6 includes an auxiliary conveyor belt 63, a left lifting rod 61 and a right lifting rod 62. The left lifting rod 61 and the right lifting rod 62 are both mounted on the moving platform 21. A straight groove 64 is provided in the middle of the auxiliary conveyor belt 63.

[0078] The top of the left lifting rod 61 is rotatably connected to one end of the auxiliary conveyor belt 63 near the horizontal rotating trough frame 4; the top of the right lifting rod 62 is provided with a connecting rod, which is located at the straight trough opening 64. The left lifting rod 61 and the right lifting rod 62 are independent of each other, so that the auxiliary conveyor belt 63 is flush with or tilted and raised with the rectangular frame 51.

[0079] like Figure 7 As shown, the auxiliary conveyor mechanism 6 has two working states when performing auxiliary conveying: The first state is that the left lifting rod 61 and the right lifting rod 62 rise and fall synchronously. At this time, the auxiliary conveyor belt 63 rises and falls horizontally. This state is suitable when the main conveyor mechanism 5 is at the height of the carriage floor. At this time, the auxiliary conveyor belt 63 is also at the height of the carriage floor. The staff can manually place the cigarette box at the right end of the auxiliary conveyor belt 63. The second state is that the left lifting rod 61 rises and falls together with the main lifting push rod 3, while the right lifting rod 62 remains stationary or descends. This state is suitable when the main conveyor mechanism 5 is at the height of the carriage roof. At this time, the left end of the auxiliary conveyor belt 63 rises and its right end descends. After the manual cigarette box is put in from the right end of the auxiliary conveyor belt 63, it gradually climbs with the auxiliary conveyor belt 63 to the current height of the main conveyor mechanism 5, and then enters the front end of the main conveyor mechanism 5.

[0080] When the auxiliary conveyor 6 and the main conveyor 5 are transferring the smoke box, the top surface of the auxiliary conveyor belt 63 is higher than the top surface of the main conveyor 5, so that the smoke box can smoothly enter the front end of the main conveyor 5 from the left end of the auxiliary conveyor belt 63.

[0081] Among them, the main lifting push rod 3, the left lifting rod 61 and the right lifting rod 62 are multi-layer lifting rods. Their structure is widely used in the telescopic boom of cranes or screw jacks. It belongs to mature and reliable existing technology. Therefore, in this embodiment of the invention, the main lifting push rod 3 can drive a series of components on the horizontal rotating trough frame 4 and the main conveying mechanism 5, as well as the goods such as cigarette boxes supported by them, to lift and lower. The left lifting rod 61 and the right lifting rod 62 can carry the auxiliary conveyor belt 63 to perform the above-mentioned overall lifting and angle deflection lifting.

[0082] Furthermore, multiple rows of dome support rods 41 are movably connected to the inner slot of the horizontal rotating trough frame 4 through a perforated plate. The dome support rods 41 and the friction belt 56 are arranged alternately, and the height of the top of the dome support rods 41 rises and falls between above and below the vertical height of the top surface of the friction belt 56. The dome support rods 41 are used to roll and support the cigarette boxes conveyed on the auxiliary conveyor belt 63.

[0083] When the cigarette box moves from the top of the left end of the auxiliary conveyor belt 63 to the top front end of the main conveyor mechanism 5, the top of the three rows of ball-top support rods 41 is above the horizontal level of the top surface of the friction belt 56. The bottom surface of the cigarette box will first contact the top of the three rows of ball-top support rods 41. At this time, the three rows of ball-top support rods 41 provide rolling support for the bottom surface of the cigarette box, allowing the cigarette box to be smoothly transported from the auxiliary conveyor belt 63 to the front end of the main conveyor mechanism 5. Then, the top of the three rows of ball-top support rods 41 drops to below the horizontal level of the top surface of the friction belt 56, and the bottom surface of the cigarette box contacts the top surface of the friction belt 56. Then, it is moved by the friction belt 56 to the rear end of the main conveyor mechanism 5.

[0084] Furthermore, a docking auxiliary motor 44 is also provided inside one side of the horizontal rotating slot frame 4, and the output shaft of the docking auxiliary motor 44 is fixedly connected to a docking auxiliary lead screw 46; a wedge-shaped lifting plate 45 is also provided inside the horizontal rotating slot frame 4, the top surface of the wedge-shaped lifting plate 45 supports the bottom end of the dome support rod 41, and a docking auxiliary screw hole 47 is provided on the side facing the wedge-shaped lifting plate 45, and the docking auxiliary lead screw 46 is adapted to screw into the docking auxiliary screw hole 47.

[0085] like Figure 9As shown, when the docking auxiliary motor 44 rotates forward, it causes the wedge-shaped lifting plate 45 to move from the front end to the rear end of the horizontal rotating slot frame 4 via the docking auxiliary lead screw 46 and docking auxiliary screw hole 47. At this time, the wedge-shaped lifting plate 45 pushes the three rows of spherical support rods 41 upward to above the horizontal position of the top surface of the friction belt 56, so that the cigarette box can be smoothly transferred from the auxiliary conveyor belt 63 to the top surface of the four friction belts 56. When the docking auxiliary motor 44 rotates in reverse, it causes the wedge-shaped lifting plate 45 to move from the rear end to the front end of the horizontal rotating slot frame 4 via the docking auxiliary lead screw 46 and docking auxiliary screw hole 47. At this time, the wedge-shaped lifting plate 45 no longer supports the bottom surface of the three rows of spherical support rods 41, and the three rows of spherical support rods 41 fall below the horizontal position of the top surface of the friction belt 56. Then, the bottom surface of the cigarette box contacts the top surface of the four friction belts 56, and then moves back and forth under the movement of the four friction belts 56.

[0086] Furthermore, the position adjustment mechanism 2 also includes an adjustment motor 22, which is fixed to one end of the equipment base plate 1. The output shaft of the adjustment motor 22 is fixedly connected to an adjustment screw 23. An adjustment nut 24 is fixed to the bottom side of the moving table 21 near the adjustment motor 22. The adjustment screw 23 and the adjustment nut 24 are fitted together to drive the moving table 21 to move horizontally through the adjustment motor 22.

[0087] As described above, when the position adjustment mechanism 2 needs to move the main lifting push rod 3, the horizontal rotating slot frame 4, the main conveying mechanism 5 and the auxiliary conveying mechanism 6 in the width direction of the carriage, the adjustment motor 22 can be started. The adjustment motor 22 then drives the above components to reciprocate along the top surface of the equipment base plate 1 through the adjustment screw 23 and the adjustment nut 24 so as to stack the cigarette boxes in the width direction of the carriage.

[0088] Furthermore, four omnidirectional casters 13 and four electric support feet 14 are fixedly connected to the corners of the bottom surface of the equipment base plate 1, with the four omnidirectional casters 13 and the four electric support feet 14 being staggered.

[0089] When the bottom ends of the four electric support feet 14 retract to the equipment base plate 1, the four omnidirectional casters 13 can support the equipment base plate 1 and other components on its top to move flexibly, so as to move and adjust their position in the working area; when the equipment base plate 1 moves to align with the carriage door frame and is adjusted to the correct position, the four electric support feet 14 can be extended forward to the bottom surface of the omnidirectional casters 13, at which point the four electric support feet 14 provide stable support for the equipment base plate 1 and other components on its top.

[0090] Furthermore, a front vertical side plate 11 is fixedly connected to the front side of the equipment base plate 1, and a rear vertical side plate 12 is fixedly connected to the rear side. Electromagnets are fixedly connected to both ends of the outer walls of the front vertical side plate 11 and the rear vertical side plate 12.

[0091] As described above, when the front side of the equipment base plate 1 is aligned with the first car door frame, the front vertical side plate 11 is magnetically attracted to the first car door frame by the electromagnet at its top. At this time, the equipment base plate 1 and other components can be fixed at the first car door frame. The indexing motor 15 causes the horizontal rotating slot frame 4 and the main conveying mechanism 5 to rotate positive ninety degrees. Then, the above-mentioned cigarette box loading and unloading operation can be performed on the first car.

[0092] When the rear side of the equipment base plate 1 aligns with the door frame of the second car, the rear vertical side plate 12 magnetically attracts the door frame of the second car through the electromagnet at its top.
