Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, and in particular to a flipping conveyor device. Background Technology

[0002] In the automatic packing and labeling production line for antifreeze valves, the pre-folded cardboard boxes for holding 4 to 14-inch antifreeze valves need to be stacked on the production line with the box opening facing upwards, so as to facilitate uniform packing later.

[0003] Existing cardboard box flipping conveyors often employ a clamping device with a rotating component for flipping. This device mainly includes a lifting component, a clamping component fixed to the lifting component, and a rotating component fixed between the lifting and clamping components. When flipping is required, the lifting component lowers the clamping component, which then clamps the cardboard box. The lifting component then raises the clamping component holding the cardboard box, and the rotating component flips the cardboard box. Finally, the lifting component lowers the clamping component, and the clamping component releases the cardboard box, completing the flipping operation. However, this solution requires lifting and lowering the cardboard box before and after flipping to prevent collisions with the conveyor. This process is time-consuming and affects conveying efficiency. Furthermore, the clamping device with the rotating component is prone to vibration at the far end when flipping longer cardboard boxes, increasing the risk of the cardboard box detaching from the clamping component. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a flipping conveyor device that offers high conveying efficiency and avoids the risk of cardboard boxes detaching.

[0005] This utility model is achieved through the following technical solution:

[0006] A flipping conveyor for flipping and conveying a cardboard box, comprising:

[0007] At least one flipping component, the flipping component including a rotating shaft, a drive motor and at least one flipping frame, the rotating shaft being connected to the drive motor and rotating under the drive of the drive motor, and the flipping frame being coaxially and fixedly connected to the rotating shaft;

[0008] A conveyor table includes a table surface with an opening. A tilting frame is rotatably disposed within the opening. The tilting frame is cross-shaped and includes multiple first tilting surfaces. In the initial state, one of the first tilting surfaces is coplanar with the table surface.

[0009] Furthermore, in at least one of the flipping components, the flipping frames on two adjacent flipping components are arranged alternately in the same opening.

[0010] Furthermore, the flipping assembly also includes a fixing member, which is sleeved and fixed on the rotating shaft and fixedly connected to the flipping frame.

[0011] Furthermore, the flipping assembly also includes a sensor assembly for detecting whether there is a cardboard box to be flipped on the flipping frame.

[0012] Furthermore, the flipping assembly also includes at least one pair of bearings, through which the rotating shaft passes.

[0013] Furthermore, the conveyor table also has a first shaft hole for mounting the bearing.

[0014] Furthermore, the flipping conveyor also includes a pushing component for pushing the flipped cardboard box away along the conveyor table direction.

[0015] Furthermore, the pushing component includes a dual-axis motion module and a pusher plate, the dual-axis motion module being fixedly connected to the conveyor table, and the pusher plate being fixed on the dual-axis motion module.

[0016] Furthermore, the dual-axis motion module includes a single-axis motion module and a cylinder. The single-axis motion module is connected to the conveyor table, the cylinder is connected to the slider of the single-axis motion module, and the push plate is connected to the cylinder and reciprocates perpendicular to the single-axis motion module under the drive of the cylinder.

[0017] Furthermore, the push plate includes a second base plate, which is connected to the cylinder, and the second base plate has a slot at the position corresponding to the tilting frame.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. The flipping frame is set in the conveyor table. The flipping frame is driven by a motor to rotate and drive the paper box to complete the flipping and conveying.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figure 1 As shown, a flipping conveyor device according to an embodiment of the present invention is used to flip and convey a cardboard box 4, including at least one flipping component 1, a conveyor table 2, a pushing component 3, and a frame 5. The conveyor table 2 is fixed to the frame 5 by screws. The flipping component 1 is disposed in the conveyor table 2 to flip the cardboard box 4 located on the conveyor table 2. The pushing component 3 is fixed above the conveyor table 2 to push the flipped cardboard box 4 away along the direction of the conveyor table 2.

[0035] like Figures 2-6 As shown, the flipping assembly 1 includes a rotating shaft 10, a drive motor 11, and at least one flipping frame 12. The rotating shaft 10 is connected to the drive motor 11 and rotates under the drive of the drive motor 11. The flipping frame 12 is coaxially and fixedly connected to the rotating shaft 10.

[0036] The conveyor table 2 includes a table surface 212 with openings 211. A tilting frame 12 is rotatably disposed within each opening 211. The number of openings 211 is the same as the number of tilting frames 12 on a tilting assembly 1. Tilting frames 12 on adjacent tilting assemblies 1 are arranged alternately within the same opening 211. The tilting frame 12 is cross-shaped and includes multiple first tilting surfaces 121. In the initial state, one of the first tilting surfaces 121 is coplanar with the table surface 212.

[0037] In this embodiment, the paper box 4 to be flipped is a square paper box. The paper box 4 is flipped 270° in the flipping conveyor so that the opening faces upward. Therefore, this embodiment is provided with 3 sets of flipping components 1. Optionally, if the paper box 4 is to be flipped 90° or 180°, it can be achieved by providing 1 or 2 sets of flipping components 1.

[0038] Further reference Figure 3 The flipping conveyor also includes a motor compartment 14. A first screw hole 111 is provided on the mounting base of the drive motor 11, and the drive motor 11 is fixed inside the motor compartment 14 by screws passing through the first screw hole 111. A second shaft hole 141 is provided on the side of the motor compartment 14, and one end of the rotating shaft 10 passes through the second shaft hole 141 and connects to the drive motor 11. To accommodate the length of the cardboard box 4, four flipping frames 12 are mounted on each rotating shaft 10. Optionally, the number of flipping frames 12 can be increased or decreased to accommodate cardboard boxes 4 of different lengths, ensuring that cardboard boxes 4 of different sizes can be flipped continuously and stably.

[0039] In addition, the flipping assembly 1 also includes a sensor assembly 13, which is fixedly mounted on one side of the conveyor table 2 to detect whether there is a cardboard box 4 to be flipped on the flipping frame 12. In this embodiment, the sensor assembly 13 includes a sensor 131 and a fixing bracket 132 for fixing the sensor 131. The fixing bracket 132 is an L-shaped bracket, and the sensor assembly 13 is fixed to one right-angled side of the fixing bracket 132 by screws. The other right-angled side of the fixing bracket 132 is fixed to the conveyor table 2 by screws. In this embodiment, three sets of flipping assemblies 1 are provided, and four sensors 131 are provided, with the four sensors 131 and the three sets of flipping assemblies 1 distributed alternately. Preferably, the type of sensor 131 is a photoelectric sensor.

[0040] The flipping assembly 1 also includes a fixing member 125 and at least a pair of bearings 124. The fixing member 125 is sleeved and fixed on the rotating shaft 10 and fixedly connected to the flipping frame 12. The two ends of the rotating shaft 10 are inserted into a pair of bearings 124.

[0041] Specifically, refer to Figure 5The tilting frame 12 has a central hole 123 at its geometric center for the rotating shaft 10 to pass through, and four third screw holes 127 are formed around the central hole 123. The fixing member 125 has an opening 129 along its axial direction, and three fourth screw holes 128 are provided on its end face corresponding to the third screw holes 127. The fixing member 125 also has a second screw hole 126 tangentially extending through the opening 129. The fixing member 125 and the tilting frame 12 are then fixedly connected by screws passing through the third screw holes 127 and the fourth screw holes 128. The fixing member 125 and the tilting frame 12 are then fitted together onto the rotating shaft 10, and the screws passing through the second screw holes 126 are tightened to make the fixing member 125 grip the rotating shaft 10, thus achieving the purpose of fixing the tilting frame 12 to the rotating shaft 10.

[0042] Further reference Figure 5 and Figure 6 In this embodiment, the flipping frame 12 includes four first flipping surfaces 121 and four second flipping surfaces 122. Initially, one of the first flipping surfaces 121 is horizontal and coplanar with the table surface 212. When a square cardboard box 4 enters the first flipping frame 12, the bottom surface of the cardboard box 4 adheres to the first flipping surface 121, and one side of the cardboard box 4 adheres to the second flipping surface 122. During flipping, the first flipping surfaces 121 and 122 together rotate the cardboard box 4 by 90°. After the flipping frame 12 completes its first flip, the next first flipping surface 121 of the flipping frame 12 enters a horizontal state to await the next cardboard box 4. The flipped cardboard box 4 presses onto the first flipping surface 121 of the next flipping frame 12, and subsequent flipping frames 12 repeat the above actions to achieve continuous flipping.

[0043] like Figure 7 As shown, the conveyor table 2 includes a first base plate 21, a pair of side plates 22 and a support plate 23. The table surface 212 is formed on the first base plate 21. The pair of side plates 22 are fixed to both sides of the first base plate 21 by welding. The two ends of the support plate 23 are respectively fixed to the pair of side plates 22 by screws and span across the top of the first base plate 21. The conveyor table 2 also has a first shaft hole 221 for installing the bearing 124.

[0044] In this embodiment, there are four flipping frames 12 on each rotating shaft 10, therefore, there are four openings 211 on the first base plate 21. The side plate 22 includes a first side portion 222 and a second side portion 223. The first side portion 222 is fixed to the first base plate 21 by welding. The first side portion 222 has three first shaft holes 221 and four observation holes 224. The first shaft holes 221 are lower than the table surface 212 in the vertical direction. A pair of bearings 124 are respectively set in the first shaft holes 221 on both sides of the base plate. The rotating shaft 10 is fixed in the conveyor table 2 by passing through the pair of bearings 124. The observation holes 224 correspond to the position and number of sensors 131 and are used to detect whether there are paper boxes 4 passing in front of or behind the flipping frames 12. The second side portion 223 is a rectangular frame, and the second side portion 223 is connected to the first side portion 222 by screws.

[0045] like Figure 8 and Figure 9 As shown, the pushing component 3 is fixed on the support plate 23 and is used to push the flipped cardboard box 4 away along the conveyor table 2. The pushing component 3 includes a dual-axis motion module 31 and a push plate 32. The dual-axis motion module 31 is fixedly connected to the conveyor table 2, and the push plate 32 is fixed on the dual-axis motion module 31. Specifically, the dual-axis motion module 31 includes a single-axis motion module 311 and a cylinder 312. The single-axis motion module 311 is fixed to the support plate 23 of the conveyor table 2 by screws, and the cylinder 312 is fixed to the slider 313 of the single-axis motion module 311 by screws. The push plate 32 is fixedly connected to the cylinder 312 by screws and reciprocates perpendicular to the single-axis motion module 311 under the drive of the cylinder 312. Preferably, the cylinder 312 in this embodiment is a dual-axis cylinder. The push plate 32 includes a second base plate 321, which is connected to the cylinder 312, and the second base plate 321 has a slot 322 at the position corresponding to the flipping frame 12. The push plate 32 also includes a pressure plate 323, which is fixedly connected to the second base plate 321 and is used to press the paper box 4.

[0046] Furthermore, to avoid motion interference between the second base plate 321 and the flipping bracket 222, the number of slots 322 is determined by the specific length of the second base plate 321. The longer the second base plate 321 is, the more flipping brackets 12 it intersects with, and the more slots 322 there are. In this embodiment, there are 3 slots 322. In addition, the second base plate 321 is also provided with a sixth screw hole 324 for fixing to the cylinder 312 and a seventh screw hole 325 for fixing to the pressure plate 323. The pressure plate 323 has an L-shaped structure, and a long slot 326 is provided on the right-angled side that is fixed to the second base plate 321. Screws and other fasteners can be passed through the long slot 326 and the seventh screw hole 325 to fix the pressure plate 323 to the second base plate 321.

[0047] like Figure 10 as well as Figure 11 As shown, a thicker arrow is marked on the side of the cardboard box 4. This thicker arrow is only a schematic marker indicating the state of the cardboard box 4 itself and does not represent that the cardboard box 4 actually has this mark. The thinner arrow indicates the displacement direction and flipping direction of the cardboard box 4 on the table 212. When the flipping conveyor device corresponding to this embodiment is working, the cardboard box 4 enters the left side of the first flipping frame 12. At this time, the thicker arrow points to the right, corresponding to the initial state of the cardboard box 4. When the first sensor 131a, located to the left of the first flipping frame 12, detects the cardboard box 4, it sends a signal to the controller 6. The controller 6 then controls the first drive motor 11 to operate, driving the first flipping frame 12 to rotate clockwise, rotating the cardboard box 4 between the first and second flipping frames 12. At this point, the thicker arrow points downwards. After the second sensor 131b, located at this point, detects the presence of the cardboard box 4, it sends a signal to the controller 6. The controller 6 then controls the second drive motor 11 to operate, driving the second flipping frame 12 to rotate clockwise, rotating the cardboard box 4 between the second and third flipping frames 12. At this point, the thicker arrow points to the left. After the third sensor 131c detects the cardboard box 4, the above process is repeated until the cardboard box 4 reaches the right side of the third flipping frame 12. At this point, the thicker arrow points upwards, corresponding to the final state of the cardboard box 4.

[0048] Initially, the pusher plate 32 is positioned above the third flipper 12. When the fourth sensor 131d, located to the right of the third flipper 12, detects the presence of the paper tray 4, it sends a signal to the controller 6. The controller 6 then controls the cylinder 312 to actuate, causing the pusher plate 32 to fall and engage the paper tray 4. The single-axis motion module 311 then drives the pusher plate 32 to move to the right, pushing the paper tray 4 away from the conveyor table 2. Once the paper tray 4 reaches the preset position, the pusher assembly 3 resets and awaits the next action.

[0049] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
