One end of each palletizing transfer mechanism is distributed on one side of the palletizing manipulator, and the other end of each palletizing transfer mechanism extends from a corresponding conveying door to the loading area; the gantry crane hoisting mechanism is installed in the loading area.

[0006] Furthermore, the number of the palletizing and transferring mechanisms is at least two, and each of the palletizing and transferring mechanisms includes two tracks, a loading platform and a traveling mechanism; the two tracks are arranged in parallel on the ground, and the two tracks pass through a corresponding conveying door; the traveling mechanism is installed at the bottom of the loading platform and moves along the two tracks to enter and exit the conveying door.

[0007] Furthermore, the automatic rolling door is installed on one side of the conveying door, and a hot air curtain is provided on the other side of the conveying door.

[0008] Furthermore, the main sugar bag conveying line includes a plurality of straight belt conveyors, a plurality of slow-down belt conveyors and a plurality of turning belt conveyors; the straight belt conveyors, the slow-down belt conveyors and the turning belt conveyors are assembled in series end to end according to the conveying direction requirements.

[0009] Furthermore, the end of the main sugar bag conveying line is a straight belt conveyor, and a slow-down belt conveyor is provided upstream of the straight belt conveyor on the side opposite to the palletizing manipulator.

[0028] Refer to Figures 1 to 3As shown in the figure, a sugar packet transfer automatic palletizing and loading system includes several sugar bag packaging machines 1, a main sugar packet conveying line 2, a sugar packet shaping mechanism 3, a palletizing manipulator 4, several palletizing transfer mechanisms 5, and a gantry crane hoisting mechanism 6. The discharge ports of several sugar bag packaging machines 1 are docked with the main sugar packet conveying line 2, and the sugar packets coming out of the sugar bag packaging machines 1 can be directly sent onto the main sugar packet conveying line 2. A heat preservation room 7 is provided at the end of the main sugar packet conveying line 2. The palletizing manipulator 4 is installed inside the heat preservation room 7, on one side of the end of the main sugar packet conveying line 2. After being conveyed by the main sugar packet conveying line 2, the sugar packets are conveyed to one side of the palletizing manipulator 4 waiting for palletizing. In order to enable the palletizing manipulator 4 to grasp the sugar packets more precisely, a sugar packet shaping mechanism 3 is also provided on the main sugar packet conveying line 2, located upstream of the palletizing manipulator 4, to level and unify the shapes of the conveyed sugar packets in advance. One side outside the heat preservation room 7 is set as a loading area 8. The loading area is outdoors. Therefore, several conveying doors 9 are provided between the heat preservation room 7 and the loading area 8. An automatic rolling door 10 is provided at each conveying door 9. One end of each palletizing transfer mechanism 5 is distributed on one side of the palletizing manipulator 4, and the other end of each palletizing transfer mechanism 5 extends from a corresponding conveying door 9 to the loading area 8. The gantry crane hoisting mechanism 6 is installed in the loading area 8. The gantry crane hoisting mechanism has been publicly disclosed in the prior art and will not be elaborated here. The working principle of the present utility model is that the main sugar packet conveying line 2 receives the sugar packets coming out of the sugar bag packaging machines 1 and conveys them to the palletizing position. The palletizing manipulator 4 transfers the sugar packets into the ton bags on the palletizing transfer mechanism 5. The palletizing transfer mechanism 5 conveys the palletized sugar packets from the conveying window 99 to below the gantry crane hoisting mechanism 6 in the loading area. Manual bag hanging is adopted. The gantry crane hoisting mechanism 6 hoists and loads the palletized sugar packets. The automatic rolling door 10 automatically opens during conveying and automatically closes after conveying is completed, which can reduce the influence on the temperature and humidity inside the heat preservation room 7 and also reduce the influence of sand, dust, etc. on the cleanliness of the heat preservation room 7. By combining the sugar bag packaging machines 1, the main sugar packet conveying line 2, the sugar packet shaping mechanism 3, the palletizing manipulator 4, several palletizing transfer mechanisms 5, and the gantry crane hoisting mechanism 6, the present utility model forms a conveying system that can automatically convey, automatically level and shape, automatically palletize, automatically transfer, and load. Using the belt conveying and gantry crane scheme for loading is more convenient and faster than using a forklift, with strong practicability. There is no safety risk to personnel during hoisting, the equipment maintenance cost is extremely low, and it is more economical compared with a forklift. It can solve the disadvantages of the existing mainstream forklift transfer and loading methods, such as large floor space occupation, low operating efficiency, high operating cost, and pollution to the site environment and products. It has a more efficient and safer operation effect, and manual handling and forklift consignment are avoided during the conveying process, preventing the sugar packets from being damaged artificially or mechanically during the transfer and transportation process, ensuring the integrity of the packaging and the cleanliness of the sugar packet appearance.

[0029] The number of the palletizing and transferring mechanisms 5 is at least two. Each palletizing and transferring mechanism 5 includes two tracks 51, a loading platform 52 and a traveling mechanism 53; the two tracks 51 are arranged in parallel on the ground, and the two tracks 51 pass through a corresponding conveying door 9; the traveling mechanism 53 is installed at the bottom of the loading platform 52 and moves along the two tracks 51 to enter and exit the conveying door 9. Through two palletizing and transferring mechanisms 5, the transfer work of the palletized sugar bags can be alternately completed, and the continuous transfer and transportation work can be realized in cooperation with the palletizing manipulator 4 and the gantry crane hoisting mechanism 6, improving the operation efficiency.

[0030] The palletizing manipulator 4 usually needs to operate in an environment with appropriate temperature and humidity. Temperature and humidity may affect its accuracy and reliability. Especially in winter in the north or northwest of China, the temperature difference between indoors and outdoors is relatively large. Therefore, the present utility model arranges the palletizing manipulator 4 in the heat preservation room 7. A conveying door 9 is opened between the heat preservation room 7 and the loading area 8. An automatic rolling door 10 and a hot air curtain 11 are respectively installed on both sides of the conveying door 9. When the automatic rolling door 10 is opened, the hot air curtain 11 is synchronously opened to block the cold air outside from entering, so as to ensure that the temperature and humidity in the heat preservation room 7 are not affected and provide the best working environment for the palletizing manipulator 4.

[0031] The main sugar bag conveying line 2 includes a plurality of straight belt conveyors 21, a plurality of slow-down belt conveyors 22 and a plurality of turning belt conveyors 23; the straight belt conveyors 21, the slow-down belt conveyors 22 and the turning belt conveyors 23 are serially assembled and spliced end to end according to the conveying direction requirements. The end of the main sugar bag conveying line 2 is a straight belt conveyor 21, and there is a slow-down belt conveyor 22 upstream of the straight belt conveyor 21 on the side opposite to the palletizing manipulator 4. A plurality of photoelectric sensors are arranged on the slow-down belt conveyor 22, and a retractable blocking block is further arranged at its end. Whether there is material on the slow-down belt conveyor 22 is sensed by the photoelectric sensors, and then the conveying speed is controlled to achieve a buffering effect. An additional photoelectric sensor needs to be installed on the blocking block at the end to sense whether there is still material remaining in the subsequent process, so as to judge whether to release the blocking block. The slow-down belt conveyor 22 can slow down the conveying speed of the sugar bags and can realize material buffering for some special processes such as palletizing work, inspection work, leveling work, etc.

[0032] An emergency belt conveyor 24 is further arranged at the end of the main sugar bag conveying line 2. The function of the emergency belt conveyor 24 is to prevent special situations and can be used as a temporary storage area for abnormal sugar bags.

[0033] The sugar bag shaping mechanism 3 is a double-belt shaping conveyor line, and the double-belt shaping conveyor line is connected in series in the main sugar bag conveying line. The double-belt shaping conveyor line is a prior art and will not be elaborated here.

[0034] The sugar packet transfer automatic palletizing and loading system further includes a detection mechanism 25 and a defective product rejection mechanism 26 that are sequentially installed on the main sugar packet conveying line 2. The detection mechanism 25 is erected above one of the linear belt conveyors 21. The defective product rejection mechanism 26 is installed downstream of the detection mechanism 25.
