Description

Technical Field

[0001] This application relates to the technical field of cargo loading and stacking, and in particular to a stacking device and method at the end of a conveyor line for cargo loading. Background Technology

[0002] To reduce the labor intensity of loading boxed goods and improve the loading efficiency, such as loading whole cases of milk, a dispersing conveyor device is usually used in conjunction with a stacking device to automate the loading of boxed goods.

[0003] During the loading of boxed goods, since the width of the truck bed is fixed, it is necessary to calculate the number of boxed goods that the stacking device can stack each time based on the length and width of the boxed goods, so as to minimize the gap between the entire row of boxed goods stacked by the stacking device and the side wall of the truck bed.

[0004] In the above technical solution, the optimal stacking quantity is calculated based on the length and width of the boxed goods. Compared with stacking directly with a single size, it can achieve a smaller gap size. However, its combination flexibility is still poor, and the minimum gap size is still relatively large. Therefore, there is an urgent need for a stacking device that can more flexibly combine and arrange boxed goods. Summary of the Invention

The photoelectric sensors are mounted on the stacking platform and are used to output the position signal of the boxed goods. The controller is electrically connected to the photoelectric sensors and all the drive components respectively. Based on the flipping status of the boxed goods, the controller responds to the position signal and is used to control the action of the drive components.

[0011] Optionally, the controller can control the drive unit corresponding to the first flip roller and the drive unit corresponding to the second flip roller in a coordinated manner. When the controller controls the drive unit corresponding to the second flip roller to drive the second flip roller to rise, the controller simultaneously controls the drive unit corresponding to the first flip roller to drive the first flip roller to descend.

[0012] Optionally, a stabilizing mechanism is also included, which includes a stabilizing plate and a drive assembly. The stabilizing plate is mounted on the stacking platform via the drive assembly, which is used to drive the stabilizing plate to move up, down, and sideways. The original top surface of the boxed goods in the horizontal state can abut against the stabilizing plate after being flipped.

[0013] Optionally, the drive assembly includes a first slide, a sliding screw, a sliding motor, a lifting bracket, a second slide, a lifting screw, and a lifting motor. The first slide is slidably mounted on the stacking frame along the conveying direction of the discharge conveyor.

[0014] Optionally, a receiving conveyor and a stacking conveyor are also included. Both the receiving conveyor and the stacking conveyor are mounted on a stacking platform. The receiving conveyor is located near the feeding end of the discharging conveyor. The receiving conveyor is used to receive boxed goods and push them to the discharging conveyor. The stacking conveyor is located on one side of the conveying direction of the discharging conveyor. The discharging conveyor is used to push rows of boxed goods to the stacking conveyor with its own unloading end as a reference.

Container goods in the length direction parallel to the conveyor direction of the discharge conveyor are placed next to the container goods that were previously placed. Container goods in the width direction parallel to the conveyor direction of the discharge conveyor are placed next to the container goods that were previously placed.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. This application discloses a stacking device at the end of a conveyor line for loading goods, comprising a stacking platform, a discharge conveyor, and a box-turning mechanism. The discharge conveyor enables the boxed goods it receives to be arranged in rows with its discharge end as the reference. When it is necessary to turn the boxed goods, the first turning roller is raised to stop the boxed goods from being conveyed further, the third turning roller is raised to drive the boxed goods to turn, and then the second turning roller is raised to make the boxed goods stand up. The first turning roller descends synchronously to assist the boxed goods in being gradually placed on the conveyor roller during the turning process. This allows the height dimension of the boxed goods to be matched with the length and width dimensions of the boxed goods to be arranged in rows.

[0019] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0020] This application discloses an end-of-line stacking device for loading goods onto vehicles. (Refer to...) Figure 1 and Figure 2A stacking device at the end of a conveyor line for loading goods includes a stacking platform 1 and a discharge conveyor 2 set on the stacking platform 1. A box-flipping mechanism 3 is provided at the discharge conveyor 2, which is used to flip the boxed goods along the conveying direction of the discharge conveyor 2.

[0021] In use, the discharge conveyor 2 picks up boxed goods and transports them one by one to its unloading end. The first boxed goods abuts against the side wall of the carriage, so that all the boxed goods are arranged in a row. When it is necessary to flip the boxed goods so that the height of the boxed goods matches the length and width of the boxed goods, the flipping mechanism 3 flips the required number of boxed goods one by one along the conveying direction of the discharge conveyor 2, so that the height of the boxed goods can match the length and width of the boxed goods to combine and arrange the boxed goods into a row. This minimizes the gap between the boxed goods and the side wall of the carriage when the whole row is stacked. Thus, this application can combine and arrange the whole row of boxed goods through three dimensional parameters, further improving the flexibility of the combination and arrangement of the whole row of boxed goods, and further reducing the gap value between the whole row of boxed goods and the side wall of the carriage.

[0022] Specifically, refer to Figure 2 and Figure 3 The discharge conveyor 2 includes multiple conveying rollers 21 rotatably mounted on the stacking platform 1, with a gap between adjacent conveying rollers 21. The box-turning mechanism 3 includes multiple turning rollers 31, which are arranged one-to-one between adjacent conveying rollers 21. A driving component 32 is provided between the turning rollers 31 and the stacking platform 1. The driving component 32 is used to drive the turning rollers 31 to rise and fall, so that the turning rollers 31 can be raised out of the conveying plane of the conveying rollers 21.

[0023] Reference Figure 3 In this device, at least three flipping rollers 31 are raised and lowered to flip the boxed goods. The first flipping roller 31 is located in front of the boxed goods in the conveying direction and is always in contact with the boxed goods during flipping. The second flipping roller 31 is located below the bottom surface of the boxed goods in the horizontal state before flipping and is in contact with the original bottom surface of the boxed goods in the vertical state after flipping. The third flipping roller 31 is located on the side of the second flipping roller 31 away from the first flipping roller 31 and is located below the bottom surface of the boxed goods in the horizontal state before flipping.

[0024] The first flipping roller 31 is determined by the distance between the boxed goods to be flipped and the side wall of the carriage or the boxed goods after the previous flipping. Sufficient space is left between the first flipping roller 31 and the side wall of the carriage or the boxed goods after the previous flipping.

[0025] To clearly illustrate the flipping process of the flipping roller 31 on the boxed goods, the first flipping roller 31 is referred to as flipping roller No. 1, the second flipping roller 31 as flipping roller No. 2, and the third flipping roller 31 as flipping roller No. 3. Flipping roller No. 1 and flipping roller No. 2 are arranged adjacent to each other, and flipping roller No. 1, flipping roller No. 2 and flipping roller No. 3 all conform to the characteristics of their respective flipping roller 31.

[0026] Reference Figures 4-7 First, the No. 1 flipping roller is driven by the drive unit 32 to lift it out of the conveying plane of the conveying roller 21. The No. 1 flipping roller blocks the continued conveying of the boxed goods. The No. 3 flipping roller is driven by the drive unit 32 to lift and push the boxed goods to move. Under the blocking action of the No. 1 flipping roller, the boxed goods can be flipped with the No. 1 flipping roller as support and pushed by the No. 3 flipping roller. During this process, other flipping rollers 31 that meet the characteristics of the third flipping roller 31 can be simultaneously driven by the drive unit 32 to lift them to assist the boxed goods in flipping.

[0027] When the original bottom surface of the boxed goods in a horizontal state comes into contact with the No. 2 flipping roller, the No. 2 flipping roller is driven by the drive unit 32 to lift and push the boxed goods to flip. At this time, the No. 1 flipping roller is driven by the drive unit 32 to descend to cooperate with the flipping of the boxed goods. The No. 3 flipping roller is driven by the drive unit 32 to continue to lift to assist the flipping of the boxed goods until the top of the No. 1 flipping roller descends to a position no higher than the conveying plane of the conveying roller 21. At this time, the boxed goods have completed the flipping.

[0028] By cooperating with at least three flipping rollers 31, the boxed goods can be stably flipped at any position on the discharge conveyor 2, and the boxed goods can occupy less space when flipping. After flipping, the boxed goods can be quickly placed to the side without long-distance transportation on the discharge conveyor 2, so that the boxed goods are not easy to tip over due to transportation after flipping. Thus, the corresponding number of boxed goods can be flipped on the discharge conveyor 2 as needed, and the flipped boxed goods are not easy to tip over.

[0029] Reference Figure 3 In order to ensure that the boxed goods can be stably and quickly placed to the side after being flipped, when there is no need to flip the boxed goods, the top of the flipping roller 31 is flush with the conveying plane of the conveying roller 21.

[0030] Since the top of the tilting roller 31 is flush with the conveying plane of the conveying roller 21, the portion of the boxed goods located between two adjacent conveying rollers 21 can be supported by the tilting roller 31. On the one hand, this allows the boxed goods in a horizontal state to be conveyed more stably on the discharge conveyor 2, and on the other hand, it allows the boxed goods in a vertical state to be conveyed stably on the discharge conveyor 2. This makes it less likely that the boxed goods in a vertical state will be difficult to convey due to the setting of the tilting roller and will stick to the side wall of the carriage or the boxed goods that have been tilted before.

[0031] Reference Figure 3 In order to facilitate the driving of the rotating roller 31 to rise and fall, the driving component 32 is an electric push rod. The fixed end of the driving component 32 is fixedly connected to the stacking platform 1, and the rotating roller 31 is rotatably connected to the movable end of the driving component 32.

[0032] The drive unit 32 can directly drive the tilting roller 31 to rise and fall by extending and retracting, making the lifting and lowering of the tilting roller 31 convenient and quick.

[0033] Reference Figure 2 and Figure 3 In order to facilitate the automatic control of the drive unit 32 to perform the action, the box-flipping mechanism 3 also includes a photoelectric sensor 33 and a controller 34.

[0034] Reference Figure 3 Multiple photoelectric sensors 33 are provided, and each one corresponds to a drive unit 32. A gap is left between the conveying roller 21 and the flipping roller 31 for the photoelectric sensor 33 to detect. The photoelectric sensor 33 is installed on the stacking frame 1 and is used to output the position signal of the boxed goods.

[0035] Reference Figure 2 and Figure 3 The controller 34 is electrically connected to the photoelectric sensor 33 and all the drive components 32 respectively. Based on the flipping of the cargo in the container, the controller 34 responds to the position signal and controls the action of the drive components 32.

[0036] Based on the calculation results, the corresponding first flip roller 31 is determined. When the cargo in the box blocks the detection light of the photoelectric sensor 33 corresponding to the second flip roller 31, the controller 34 controls the drive unit 32 corresponding to the first flip roller 31 to drive the first flip roller 31 to move. The third flip roller 31 and the second flip roller 31 then move, so that the movement of the flip roller 31 can be automatically performed based on the calculation results.

[0037] Reference Figure 2 and Figure 3 In order to make the flipping drive of the flipping roller 31 more reliable for flipping the goods in the box, the controller 34 controls the drive component 32 corresponding to the first flipping roller 31 and the drive component 32 corresponding to the second flipping roller 31 in a coordinated manner.

[0038] When the controller 34 controls the drive unit 32 corresponding to the second tilting roller 31 to drive the second tilting roller 31 to rise, the controller 34 synchronously controls the drive unit 32 corresponding to the first tilting roller 31 to drive the first tilting roller 31 to fall.

[0039] Under the linkage control of the controller 34, the lifting action of the second tilting roller 31 can be synchronized with the lowering action of the first tilting roller 31, reducing the probability of cargo tilting failure.

[0040] Reference Figure 2 In order to prevent the goods in the container from shaking after being turned over, the end stacking device of the conveyor line for loading goods in this application further includes a stabilizing mechanism 4, which includes a stabilizing plate 41 and a driving component 42.

[0041] The stabilizing plate 41 is mounted on the stacking frame 1 via the drive assembly 42. The drive assembly 42 is used to drive the stabilizing plate 41 to move up, down and sideways. The original top surface of the boxed goods in the horizontal state can abut against the stabilizing plate 41 after being flipped. After abutting against the boxed goods, the stabilizing plate 41 can detach from the boxed goods under the drive of the drive assembly 42.

[0042] Based on the calculation results, the drive component 42 drives the stabilizing plate 41 to a position where the boxed goods can abut after being flipped by lifting and lateral movement. This allows the boxed goods to abut against the stabilizing plate 41 after being flipped, making it less likely for the boxed goods to shake after being flipped. This helps the boxed goods to stick to the side wall of the carriage or the previous flipped boxed goods after short-distance transportation.

[0043] Specifically, refer to Figure 2 The drive assembly 42 includes a first slide 421, a sliding screw 422, a sliding motor 423, a lifting bracket 424, a second slide 425, a lifting screw 426, and a lifting motor 427.

[0044] The first slide table 421 is slidably mounted on the stacking frame 1 along the conveying direction of the discharge conveyor 2. The sliding screw 422 is threaded through the first slide table 421 and rotatably connected to the stacking frame 1. The sliding motor 423 is fixedly connected to the stacking frame 1, and the output shaft of the sliding motor 423 is fixedly connected to the sliding screw 422.

[0045] The lifting bracket 424 is fixedly connected to the first slide 421. The second slide 425 is slidably mounted on the lifting bracket 424 in the vertical direction. The second slide 425 is fixedly connected to the stabilizing plate 41. The lifting screw 426 is threaded through the second slide 425 and rotatably connected to the lifting bracket 424. The lifting motor 427 is fixedly connected to the lifting bracket 424. The output shaft of the lifting motor 427 is fixedly connected to the lifting screw 426.

[0046] The sliding motor 423 can drive the first slide 421 to slide through the sliding screw 422 to adjust the horizontal position of the stabilizing plate 41. The lifting motor 427 can drive the second slide 425 to slide through the lifting screw 426 to adjust the vertical position of the stabilizing plate 41, so that the stabilizing plate 41 can flexibly adjust its position according to the position of the box cargo to be flipped.

[0047] Reference Figure 8 In order to facilitate the quick and easy stacking of boxed goods, the present application provides a stacking device at the end of a conveyor line for loading goods, which also includes a receiving conveyor 5 and a stacking conveyor 6.

[0048] Both the receiving conveyor 5 and the stacking conveyor 6 are mounted on the stacking platform 1. The receiving conveyor 5 is located near the loading end of the discharging conveyor 2. The receiving conveyor 5 is used to receive the boxed goods and push them to the discharging conveyor 2.

[0049] Reference Figure 8 and Figure 9 The stacking conveyor 6 is located on one side of the conveying direction of the discharge conveyor 2. The discharge conveyor 2 is used to push rows of boxed goods to the stacking conveyor 6 with its own discharge end as the reference. The stacking conveyor 6 is used to stack the entire row of boxed goods with its own discharge end as the reference. The stacking conveyor 6 stacks the entire row of boxed goods once for every two rows of boxed goods pushed by the discharge conveyor 2.

[0050] Reference Figure 2 and Figure 8 In this embodiment, a push plate 22 is provided on the side of the discharge conveyor 2 away from the stacking conveyor 6. The push plate 22 is slidably connected to the stacking frame 1. The push plate 22 is used to push the boxed goods on the discharge conveyor 2 onto the stacking conveyor 6 through a motor, lead screw and slider. The receiving conveyor 5 and the stacking conveyor 6 are both existing technologies and will not be described in detail in this embodiment. In order to stack all the boxed goods flat when they are placed vertically, the length or width of the boxed goods is an integer multiple of its own height.

[0051] The receiving conveyor 5 receives the boxed goods conveyed by the dispersing conveyor and pushes them onto the discharge conveyor 2. The discharge conveyor 2 conveys the boxed goods and arranges them in rows. The discharge conveyor 2 pushes the first row of boxed goods to the stacking conveyor 6. The stacking conveyor 6 conveys the row of boxed goods to its own unloading end. During the second rowing on the discharge conveyor 2, the box-flipping mechanism 3 flips the required number of boxed goods based on the calculation results. The discharge conveyor 2 then arranges the flipped boxed goods and the horizontal boxed goods into rows again and pushes the second row of boxed goods onto the stacking conveyor 6. The stacking conveyor 6 pushes the two rows of boxed goods into the carriage as a whole row, making it easy to stack the boxed goods in the carriage.

[0052] The implementation principle of a conveyor line end stacking device for loading goods in this application embodiment is as follows: During use, the discharge conveyor 2 receives boxed goods and transports them to its unloading end. When it is necessary to flip the boxed goods, based on calculation results, when the boxed goods block the detection light emitted by the photoelectric sensor 33 corresponding to the second flipping roller 31, the drive unit 32 drives the first flipping roller 31 to rise and block the continued transport of the boxed goods. Subsequently, the third flipping roller 31 and the second flipping roller 31 rise successively to push the boxed goods to flip. When the second flipping roller 31 rises... At that time, the first turning roller 31 descends until the boxed goods are turned over. After the required number of boxed goods are turned over, the remaining boxed goods are conveyed one by one on the discharge conveyor 2 to form rows. This allows the boxed goods to be arranged in rows by relying on their length, width and height parameters to minimize the gap between the boxed goods and the side wall of the carriage when the whole row is stacked. Thus, this application can arrange the whole row of boxed goods by using three dimensional parameters, which further improves the flexibility of the whole row of boxed goods arrangement and further reduces the gap between the whole row of boxed goods and the side wall of the carriage.

[0053] This application also discloses a method for stacking goods at the end of a conveyor line.

[0054] A method for stacking goods at the end of a conveyor line, based on the aforementioned stacking device for loading goods at the end of a conveyor line, includes the following steps: Calculate the quantity: Based on the width of the truck bed, combined with the length, width and height of the box cargo, calculate the quantity of box cargo that needs to be flipped, the quantity of box cargo in the length direction parallel to the conveying direction of the parallel discharge conveyor 2, and the quantity of box cargo in the width direction parallel to the conveying direction of the parallel discharge conveyor 2. Adjusting direction: The dispersing conveyor can adjust the number of boxed goods parallel to the conveying direction in both length and width as needed. Receiving goods: The dispersing conveyor transports the horizontally placed boxed goods to the receiving conveyor 5, and the receiving conveyor 5 pushes the boxed goods to the discharging conveyor 2 at its own discharge end; One-time push: The discharge conveyor 2 picks up the boxed goods and rows them up with its own unloading end as the reference. The discharge conveyor 2 pushes the rowed boxed goods onto the stacking conveyor 6. The stacking conveyor 6 transports the boxed goods to its own unloading end, which is the first half of the whole row stacking. Flipping the goods: Flipping the required number of boxed goods, starting with the boxed goods first conveyed to the discharge conveyor 2. The controller 34 controls the corresponding drive unit 32 to drive the first flipping roller 31 to rise according to the position signal output by the photoelectric sensor 33. The first flipping roller 31 blocks the boxed goods. The third flipping roller 31 rises and drives the boxed goods to flip. When the original bottom surface of the boxed goods abuts against the second flipping roller 31, the second flipping roller 31 rises and drives the boxed goods to continue flipping. The first flipping roller 31 descends synchronously until the boxed goods are completely flipped. All flipping rollers 31 are reset. Row of goods: The first boxed goods to be overturned are transported to a position close to the truck bed. The boxed goods that are overturned later are placed close to the previous boxed goods. The boxed goods in the length direction parallel to the conveying direction of the parallel conveying conveyor 2 are placed close to the previous boxed goods. The boxed goods in the width direction parallel to the conveying direction of the parallel conveying conveyor 2 are placed close to the previous boxed goods. Secondary pushing: The discharge conveyor 2 pushes the boxed goods that are arranged in a second row onto the stacking conveyor 6. The stacking conveyor 6 then conveys the boxed goods to its own discharge end as the second half of the entire row of goods. Row stacking: The stacking conveyor 6 pushes the entire row of boxed goods into the truck bed to complete the stacking of the boxed goods.

[0055] By using the above method, and combining the length, width, and height of the cargo in the box according to the width of the truck bed, the gap between the entire row of cargo and the side wall of the truck bed can be minimized, further improving the flexibility of the cargo arrangement and thus further reducing the gap between the entire row of cargo and the side wall of the truck bed.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
