DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0039] As mentioned above, palletizing cargo boxes can facilitate the transportation and storage of cargo boxes. In the related art, cargo boxes of various specifications are usually stacked on pallets for palletizing. Since the specifications of cargo boxes on the pallet vary greatly, there is a risk of cargo boxes falling and being damaged, and the reliability of cargo box palletizing is low.

[0040] Based on this, the present invention provides a cargo box palletizing system, including a control device and a cargo box conveying device, a pallet conveying device and a palletizing device electrically connected to the control device. Since the pallet conveying device can convey pallets of various specifications, the cargo box information of the cargo box is detected by the first detection device of the cargo box conveying device, and the control device can determine the target sequence of the pallet conveying device conveying the pallets according to the cargo box information, so that the palletizing device can palletize cargo boxes of various specifications on pallets of appropriate specifications, thereby avoiding the problem of cargo boxes falling due to the mismatch between the pallet specifications and the cargo box specifications during the palletizing process, and improving the reliability of cargo box palletizing.

[0041] The cargo box palletizing system provided according to the present invention will be described in detail below with reference to the accompanying drawings.

[0042] An exemplary embodiment of the present invention provides a container palletizing system, such as Figure 1 As shown, the container palletizing system includes: a container conveying device 10, a pallet conveying device 20, a palletizing device 30 and a control device 40. The container conveying device 10 is used to convey containers of various specifications to the to-be-palletized station 50. The container conveying device 10 is provided with a first detection device, and the first detection device is used to detect the container information of the container before the container is conveyed to the to-be-palletized station 50. The pallet conveying device 20 is used to convey pallets of various specifications to the palletizing station 60. The palletizing device 30 is used to palletize the containers at the to-be-palletized station 50 on the pallet of the palletizing station 60. The control device 40 is electrically connected to the container conveying device 10, the first detection device, the pallet conveying device 20 and the palletizing device 30. The control device 40 is used to control the pallet conveying device 20 to convey the pallet to the palletizing station 60 in a target order, so that the container information of the container palletized by the palletizing device 30 matches the specifications of the pallet on the palletizing station 60.

[0043] In this embodiment, the cargo box palletizing system includes a control device and a cargo box conveying device, a pallet conveying device and a palletizing device electrically connected to the control device. Since the pallet conveying device can convey pallets of various specifications, the first detection device of the cargo box conveying device detects the cargo box information of the cargo box, and the control device can determine the target sequence of the pallet conveying device conveying the pallets according to the cargo box information, so that the palletizing device can palletize cargo boxes of various specifications on pallets of appropriate specifications, thereby avoiding the problem of cargo boxes falling due to the mismatch between the pallet specifications and the cargo box specifications during the palletizing process, and improving the reliability of cargo box palletizing.

[0044] Exemplarily, the cargo box palletizing system also includes a cargo box outbound device 70, one end of which is connected to a cargo box outbound conveying line (not shown in the figure), so that the cargo box transmitted by the cargo box outbound device 70 can land on the cargo box conveying device 10 for transportation. The cargo box can be a cargo box for storing carbon fiber materials, a cargo box for storing daily necessities, or a cargo box for storing other goods, which is not limited here. The palletizing device 30 can be a palletizing robot, or a device capable of grabbing cargo boxes. The control device 40 can be a PLC control device.

[0045] In one embodiment, if Figure 2 As shown, the cargo box conveying equipment 10 includes a first conveying roller 12. The first conveying roller 12 includes a first conveying station 121, a second conveying station 122, a third conveying station 123 and a fourth conveying station 124 connected in sequence. The fourth conveying station 124 is used to convey cargo boxes that do not meet the requirements of the warehouse to the manual processing station 80. A first detection device is arranged on the first conveying station 121, and a blocking device 90 is arranged between the second conveying station 122 and the third conveying station 123 and between the third conveying station 123 and the fourth conveying station 124. Among them, the length of the second conveying station 122 is greater than the length of the first conveying station 121. The third conveying station 123 is connected to the station to be stacked 60, and the third conveying station 123 has a first conveying direction and a second conveying direction. The first conveying direction is used to convey cargo boxes to the fourth conveying station 124, and the second conveying direction is used to convey cargo boxes to the station to be stacked 50. The first conveying direction is different from the second conveying direction.

[0046] In this embodiment, by detecting the cargo box information through the first detection device, the cargo box that meets the requirements of the outbound delivery can be transported from the first conveying station, the second conveying station and the third conveying station to the waiting stacking station to wait for the grabbing of the stacking device. The cargo box that does not meet the requirements of the outbound delivery can also be transported from the first conveying station, the second conveying station and the third conveying station to the fourth conveying station to wait for manual processing. By detecting according to the first detection device, the cargo box that is outbound can be detected to avoid stacking the cargo box that is wrongly outbound or does not meet the requirements of the outbound delivery, thereby improving the reliability of cargo box stacking. Moreover, a blocking device is installed between the second conveying station and the third conveying station. When it is detected that there is a cargo box at the third conveying station, the blocking device is controlled to work and stop transporting the cargo box to the third conveying station. When it is detected that there is no cargo box at the third conveying station, the blocking device is controlled to stop working, so that the cargo box at the second conveying station can be transported through the third conveying station, so that the cargo box is transported in an orderly manner and the transportation efficiency of the cargo box is improved. Moreover, since the third conveying station is connected to both the station to be stacked and the fourth conveying station, by setting a blocking device between the third conveying station and the fourth conveying station, when it is detected that a cargo box that meets the requirements of the outbound delivery enters the third conveying station, the blocking station is controlled to work so that the cargo box can enter the station to be stacked. When it is detected that a cargo box that does not meet the requirements of the outbound delivery enters the third conveying station, the blocking station is controlled to stop working so that the cargo box can enter the fourth conveying station to wait for manual processing. Since the number of cargo boxes that do not meet the requirements of the outbound delivery is small, most cargo boxes will enter the station to be stacked. By setting a blocking device between the third conveying station and the fourth conveying station, the frequent operation and shutdown of the blocking device is avoided, the service life of the blocking device is improved, and the complexity of the first conveying roller is reduced. At the same time, since the first conveying station is used to detect the cargo box information of the cargo box, and the second conveying station is used to transport the cargo box that has been inspected, the length of the second conveying station is greater than the length of the first conveying station, and the second conveying station can store and transport multiple cargo boxes that have been inspected, thereby improving the conveying efficiency of the cargo box conveying equipment.

[0047] Exemplarily, the length of the second conveying station 122 is greater than the length of the third conveying station 123. The second conveying station 122 may be provided with a plurality of storage stations for storing a plurality of inspected cargo boxes.

[0048] Exemplarily, the first detection device can detect whether there is a cargo box on the first conveying station 121. The cargo box information detected by the first detection device includes the specifications of the cargo box, the type of goods in the cargo box, the production batch of the goods and other related information. When the first detection device detects that there is a cargo box at the first conveying station 121, the control device 40 controls the first conveying station 121 to stop conveying. After the first detection device detects the cargo box information, the control device 40 controls the first conveying station 121 to convey the inspected cargo box to the second conveying station 122.

[0049] Exemplarily, the first conveying roller 12 further includes a waiting conveying station 125. The waiting conveying station 125 is connected to the first conveying station 121, and the cargo box transported by the cargo box outbound device 70 can land on the waiting conveying station 125 and be conveyed to the first conveying station 121 through the waiting conveying station 125.

[0050] In one embodiment, if Figure 2 As shown, a first positioning device 51 is provided on the stacking station 50, and the first positioning device 51 is used to push the cargo box to a first preset position for positioning.

[0051] In this embodiment, the first positioning device can position the cargo box to facilitate the grabbing of the palletizing device, thereby reducing the risk of grabbing failure of the palletizing device and improving the working efficiency of the palletizing device.

[0052] Exemplarily, the first positioning device 51 may be a cylinder push rod mechanism.

[0053] In one embodiment, if Figure 3 As shown, the pallet conveying equipment 20 includes a second conveying roller 21, a first pallet warehouse 22, a second pallet warehouse 23 and a depalletizing device 24. The second conveying roller 21 includes a fifth conveying station 211, a sixth conveying station 212 and a palletizing station 60. The fifth conveying station 211 is connected to both the first pallet warehouse 22 and the second pallet warehouse 23. The fifth conveying station 211 is connected to the sixth conveying station 212 and the palletizing station 60 in sequence. The depalletizing device 24 is arranged at the fifth conveying station 211. Among them, the first pallet warehouse 22 is used to convey a plurality of first pallets to the fifth conveying station 211 along the third conveying direction. The second pallet warehouse 23 is used to convey a plurality of second pallets to the fifth conveying station 211 along the fourth conveying direction. The depalletizing device 24 is used to convey at least part of the first pallets and at least part of the second pallets of the fifth conveying station 211 to the sixth conveying station 212. The third conveying direction is different from the fourth conveying direction, and the specifications of the first pallet and the second pallet are different.

[0054] In this embodiment, since the first pallet warehouse and the second pallet warehouse can transport the first pallet and the second pallet of different specifications, the control device can divide the cargo boxes of all specifications into the first specification cargo boxes and the second specification cargo boxes according to the cargo box information, and control the stacking device to stack the first specification cargo boxes and the second specification cargo boxes on the first pallet and the second pallet respectively. By setting two specifications of pallets, not only can the cargo boxes of different specifications be stacked on different pallets according to the size of the specifications, but also the specifications of the pallets are less, which reduces the cost of the pallet conveying equipment and the complexity of the stacking of the stacking device. Moreover, through the cargo box information detected by the first detection device, the control device can determine whether the first pallet or the second pallet should be added in the stacking station after the cargo box stacking in the stacking station is completed, and remove the pallet to be added from the fifth conveying station through the destacking device and transmit it to the sixth conveying station. When the cargo box stacking is completed, the pallet of the sixth conveying station will be transmitted to the stacking station.

[0055] For example, a third pallet warehouse, a fourth pallet warehouse, and a fifth pallet warehouse with different pallet specifications can also be set up to further improve the reliability of palletizing. The palletizing station 60 can be provided with a first pallet and a second pallet, or multiple first pallets and multiple second pallets.

[0056] Exemplarily, when it is detected that the palletizing station 60 lacks a pallet, the sixth conveying station 212 transfers the pallet to the palletizing station. A blocking device may also be provided between the sixth conveying station 212 and the palletizing station 60, and when it is detected that the palletizing station 60 does not lack a pallet, the blocking device operates. When it is detected that the palletizing station 60 lacks a pallet, the blocking device stops operating.

[0057] In an exemplary embodiment, the depalletizing device 24 can lift all of the first pallets and the second pallets of the fifth conveying station 211 except the bottom pallet, so that the bottom pallet is conveyed to the sixth conveying station 212. When the first pallets and the second pallets of the fifth conveying station 211 are consumed, the control device can control the first pallet warehouse 22 and the second pallet warehouse 23 to convey pallets to the fifth conveying station 211.

[0058] Exemplarily, after the first positioning device 51 positions the cargo box, the depalletizing device 24 starts to work, and the palletizing device 30 grabs the cargo box and places the cargo box on a pallet of matching specifications. The depalletizing device 24 may be an automatic depalletizing machine.

[0059] In one embodiment, if Figure 4As shown, the cargo box palletizing system also includes a packaging device 100, which includes a third conveyor roller 110, a film wrapping device 120 and a strapping device 130. The film wrapping device 120 is used to wrap the cargo box and the pallet as a whole, and the strapping device 130 is used to package the cargo box and the pallet as a whole. The third conveyor roller 110 includes a film wrapping station 111, a seventh conveying station 112, a strapping station 113, an eighth conveying station 114 and a material unloading station 115. The film wrapping station 111 is connected to the seventh conveying station 112, the strapping station 113, the eighth conveying station 114 and the material unloading station 115 in sequence. The film wrapping device 120 is arranged at the film wrapping station 111, and the strapping device 130 is arranged at the strapping station 113.

[0060] In this embodiment, since the palletized cargo boxes and pallets are matched, the palletized cargo boxes and pallets are transported to the packaging equipment for packaging, so that the stability of the packaged pallets and cargo boxes is better, which is convenient for subsequent transportation and storage, reduces the difficulty of packaging and improves the reliability of packaging. In addition, the packaging efficiency can be improved by the film wrapping device and the strapping device. The film wrapping device can wrap the goods (pallets and cargo boxes, hereinafter referred to as pallets and cargo boxes) located at the film wrapping station with a film as a whole to form a tight protective layer, which can not only prevent dust and moisture but also prevent damage during transportation and the cargo box from falling off due to force. After the film wrapping is completed, the goods are transported to the seventh conveying station. When there are goods at the strapping station, the seventh conveying station stops conveying goods to the strapping station. When there are no goods at the strapping station, the seventh conveying station conveys goods to the strapping station, making the packaging process of the goods more orderly. The strapping device can further package the goods at the strapping station to fix and seal the wrapped goods to avoid problems such as shaking and falling of the cargo box during transportation. The packaged goods can be transported to the unloading station through the eighth conveying station to wait for the staff to transport them to the storage warehouse and other areas.

[0061] Exemplarily, when there are goods at the unloading station 115, the goods on the eighth conveying station 114 stop being conveyed to the unloading station 115. When there are no goods at the unloading station 115, the eighth conveying station 114 conveys goods to the unloading station 115.

[0062] For example, after palletizing is completed, the pallet conveyor 20 can convey the goods to the film wrapping station 111 of the packaging device 100 through the second conveyor roller 21. After detecting the presence of goods at the film wrapping station 111, the film wrapping device 120 turns its head to approach the goods and starts film wrapping. After film wrapping is completed, the head of the film wrapping device 120 turns in the opposite direction and leaves the goods. The film wrapping device 120 can be an automatic film wrapping machine.

[0063] For example, the packaged goods can be transported to a storage warehouse by forking with the forking device 140 .

[0064] In one embodiment, the film wrapping station 111 is further provided with a second detection device to detect whether there is a cargo box on the film wrapping station 111 .

[0065] In this embodiment, since the second detection device has a simple structure, the second detection device is used to detect whether a cargo box exists, thereby reducing the complexity of the packaging equipment.

[0066] Exemplarily, the second detection device may be a photoelectric sensor device.

[0067] In one embodiment, the strapping device 130 includes a strapping machine 131 and an automatic corner protecting machine 132 .

[0068] In this embodiment, when the goods are transported to the strapping station, the automatic corner protector can detect the position of the pallet and place the corner protector on the edge of the cargo box on top of the goods for the first time. After the placement is completed, the strapping machine starts to operate and straps the goods for the first time. After the first strapping is completed, the automatic corner protector retracts the corner protector, and the strapping station 113 rotates to rotate the goods 90 degrees. The automatic corner protector places the corner protector for the second time until the automatic strapping machine completes the second strapping. The strapping machine and the automatic corner protector cooperate with each other to improve the reliability of packaging the goods.

[0069] Exemplarily, there are two automatic corner protection machines 132, which are respectively arranged on both sides of the strapping station 113. The strapping device 130 also includes a strapping tape storage 133, which is connected to the strapping machine 131 and is used to provide strapping tape.

[0070] Exemplarily, the packaging equipment 100 is further provided with a maintenance platform 160 , which is arranged at the strapping station 113 for maintaining the strapping machine 131 and the automatic corner protecting machine 132 .

[0071] In one embodiment, a second positioning device is provided on the palletizing station 60, and the second positioning device is used to push the pallet to a second preset position for positioning.

[0072] In this embodiment, the pallet can be positioned by the second positioning device to facilitate the stacking device to place the cargo box, thereby reducing the risk of failure of the stacking device to place the cargo box, thereby improving the working efficiency of the stacking device.

[0073] Exemplarily, the second positioning device is used to push the first tray and the second tray to the second preset position and the third preset position respectively for positioning.

[0074] In one embodiment, the first detection device includes a camera and / or a photoelectric detection device.

[0075] In this embodiment, the photoelectric detection device can detect whether there is a cargo box at the first conveying station, and the camera can obtain cargo box information of the cargo box. Due to the simple structure of the photoelectric detection device and the camera, the complexity of the cargo box conveying equipment is reduced.

[0076] Exemplarily, the cargo box has cargo box information. After the camera captures the cargo box information, it is transmitted to the control device 40. The control device 40 reads the cargo box information and determines whether the cargo box meets the outbound requirements based on the cargo box information, so as to avoid stacking the cargo boxes that are shipped out incorrectly or do not meet the outbound requirements.

[0077] For example, the control system can also print out the number of the palletized cargo box according to the cargo box information obtained by the control device 40, and affix the number to the packaged cargo for easy identification. The control system can be an Enterprise Resource Planning (ERP) system.

[0078] For example, Figures 1 to 5 As shown, the cargo box outbound device 70 lands the cargo box on the waiting conveying station 125. When the cargo box is transmitted to the first conveying station 121, the first detection device detects the cargo box information of the cargo box. When the control device 40 determines that the cargo box meets the outbound requirements, it is conveyed to the waiting stacking station 50 through the second conveying station 122 and the third conveying station 123, and the first positioning device 51 positions the cargo box at the waiting stacking station 50. At the same time, the control device 40 determines the stacking sequence of the stacking device 30 and the sequence of the pallet conveying device 20 according to the cargo box information. When the control device 40 determines that the cargo box does not meet the outbound requirements, it is conveyed to the fourth conveying station 124 through the second conveying station 122 and the third conveying station 123. The first pallet warehouse 22 and the second pallet warehouse 23 transport the first pallet and the second pallet to the fifth conveying station 211, the depalletizing device 24 transports part of the first pallet and the second pallet to the palletizing station 60, the second positioning device positions the pallets of the palletizing station 60, and the palletizing device 30 palletizes the cargo boxes of different specifications to be palletized at the palletizing station 50 on the pallets of matching specifications in the palletizing sequence.
