[0002] Nowadays, automated control of production lines has become a trend. Existing automated production lines are generally composed of automatic conveyor tracks and automatic processing stations. In order to improve production efficiency and reduce labor costs, automatic conveyor lines are often used to transport and load trays. At present, there is a rectangular plastic pallet that can be stacked. In order to prevent the plastic pallet from being placed in the wrong direction, one of the four corners of the plastic pallet will be different from the others, such as Figure 1 As shown, one corner of the plastic pallet a is provided with a notch b, and the other three corners are rounded. When the above plastic pallets are transported by a traditional conveyor line, the following problems may occur:

[0003] 1. When the traditional conveyor line transports multiple stacked plastic pallets, the upper cover will shake due to inertia and easily collapse.

[0004] 2. During the manual loading step of the traditional conveyor line, the plastic pallet may be placed in the wrong direction, resulting in the need for reloading and conveying, which reduces efficiency.

[0005] 3. The traditional conveyor line can only convey one plate at a time, which is inefficient. Summary of the invention

[0017] like Figures 2 to 5 As shown, in this embodiment, the present invention includes a conveyor line 1, and guide baffles 2 are provided on both sides of the conveyor line 1. The guide baffles 2 on both sides include a first baffle 3, a second baffle 4 and a third baffle 5. The first baffle 3 is located at the input end of the conveyor line 1, the second baffle 4 is located in the middle section of the conveyor line 1, and the third baffle 5 is located at the output end of the conveyor line 1. The heights of the first baffle 3, the second baffle 4 and the third baffle 5 gradually increase, and the first baffle 3 and the second baffle 4 are provided with a discharge gap 6. The tops of the first baffle 3, the second baffle 4 and the third baffle 5 are all provided with outwardly bent bevels. The height of the second baffle 4 is the same as the height of the plastic pallet a to be transported stacked on the conveyor line 1, ensuring that the plastic pallet a will not shake and collapse during manual loading and transportation. The design that the first baffle 3 is lower than the second baffle 4 combined with the discharge gap 6 can facilitate manual loading. The design of the third baffle plate 5 being higher than the second baffle plate 4 can keep the plastic pallets a in order when discharging. We have found in practice that the plastic pallet a on the top layer is prone to dragging one or more of the plastic pallets a behind it when discharging. After the plastic pallet a on the top layer is extracted to a certain height, the multiple plastic pallets a can be forced to separate by swinging up and down.

[0018] In this embodiment, a front baffle 7 for preventing the plastic pallet from sliding out is provided just in front of the input end of the conveyor line 1. In this embodiment, the front baffle 7 is connected to the first baffle 3 as a whole, and the connection between the front baffle 7 and the first baffle 3 is a folded angle 8. The front baffle 7 can prevent the plastic pallet a from sliding out of the conveyor line 1, and also helps to align the plastic pallet a during loading. In this embodiment, the third baffle 5 is provided with a folded edge 21 on one side of the output end of the conveyor line 1, and the folded edge 21 is used to prevent the plastic pallet from tipping forward.

[0019] In this embodiment, a foolproof module 9 is provided at the lower part of the folded corner 8, and the foolproof module 9 includes a support plate 10 connected to the folded corner 8, a foolproof detection cylinder 11 provided on the support plate 10, a bayonet 12 provided at the output end of the foolproof detection cylinder 11 and adapted to the bottom of the foolproof corner of the plastic pallet, and a foolproof sensor 13 provided on the bayonet 12. When the plastic pallet a is placed at the entrance of the conveyor line 1, the foolproof detection cylinder 11 drives the bayonet 12 to move, and the bayonet 12 slowly approaches a corner of the plastic pallet a until the bayonet 12 is completely stuck in the rounded corner of a corner of the plastic pallet a. If the position of the plastic pallet a is correctly placed, the contact of the foolproof sensor 13 is just located at the notch b, and no alarm will occur; if the position of the plastic pallet a is incorrectly placed, the contact of the foolproof sensor 13 will touch the plastic pallet a, thereby issuing an alarm.

[0020] In this embodiment, the conveyor line 1 includes two parallel conveyor belts 14 and a motor 15 for driving the conveyor belts 14. The two conveyor belts 14 respectively support the bottoms of the two ends of the plastic pallet and convey it forward. In this embodiment, the two conveyor belts 14 are uniformly driven by the motor 15 to ensure the consistency of the movement speed of the two conveyor belts 14.

[0021] In this embodiment, a support plate 16 is provided between the two conveyor belts 14, the upper surface of the support plate 16 is not higher than the conveying surfaces of the two conveyor belts 14, a blocking cylinder 17 is provided on the bottom surface of the support plate 16, and a blocking block 18 is provided at the output end of the blocking cylinder 17, and the blocking block 18 passes through or descends from the support plate 16 under the action of the blocking cylinder 17. The design of the blocking block 18 can ensure the accuracy of the position where the plastic pallet a is conveyed.

[0022] In this embodiment, a first sensor 19 for detecting the bottommost plastic pallet is provided at the bottom of the first baffle plate 3, and a second sensor 20 for detecting the topmost plastic pallet is provided at the top of the second baffle plate 4. Through the staggered design of the first sensor 19 and the second sensor 20, it can be ensured that the stacked plastic pallets a at the feeding end will not be misjudged, thereby providing working stability.

[0023] The working principle of the present invention is as follows: Figure 6 As shown, a plastic pallet a is first placed at the feeding end of the conveyor line 1. The foolproof detection cylinder 11 drives the bayonet 12 to move, and the bayonet 12 slowly approaches a corner of the plastic pallet a until the bayonet 12 is completely stuck in the rounded corner of the corner of the plastic pallet a. If the position of the plastic pallet a is correctly placed, the contact of the foolproof sensor 13 is just located at the notch b, and no alarm will occur; if the position of the plastic pallet a is incorrectly placed, the contact of the foolproof sensor 13 will touch the plastic pallet a, thereby sounding an alarm. When the position of the plastic pallet a is correctly placed, nine more plastic pallets a are stacked. When the first sensor 19 and the second sensor 20 both sense the material, the stacking of the plastic pallets a is stopped. Then the blocking block 18 is lowered, the conveyor line 1 is started, and ten plastic pallets a are transported by the conveyor line 1 to the discharge end to be extracted. During the transportation process, the ten plastic pallets a can be effectively prevented from shaking under the action of inertia due to the action of the guide baffle 2. The present invention realizes the function of material tray transportation and preventing the plastic pallets from being placed in the wrong direction through an automated mechanism, thereby improving the automation level of the assembly line and reducing the use of personnel.

[0024] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
