[0002] As a dairy product that is deeply loved by consumers, the market demand for cheese is showing a trend of continuous growth. With the accelerated pace of modern life and the increasing requirements of consumers for food quality, convenience and hygiene, independently packaged cheese products are gradually gaining favor in the market.

[0003] When packaging individually packaged cheese, the cheese needs to be manually placed in the blister shell, and then the blister packaging machine covers the blister shell filled with cheese with a covering film, and then the roller-type heat sealing device or the flat-plate sealing device seals the covering film with the formed blister at a suitable temperature and pressure to seal the cheese in the blister. Finally, the punching device punches the continuous packaged finished product into independent products to obtain individual cheese products.

[0004] Because, during the loading process, workers are required to keep a synchronized speed with the blister packaging machine to place the cheese into the blister shell, which can easily lead to missing cheese. Also, as long as the blister packaging machine is started, workers are required to work all the time, without stopping the equipment or the workers, and the labor intensity and pressure on the workers are very high.

[0028] Job Description: 1. Preparation stage: When using this embodiment, a worker first places the produced cheese into the discharge trough 21 of the cheese discharge tray 2, and then pushes the cheese discharge tray 2 from the open end of the limit frame 31 into the limit frame 31, so that the cheese discharge tray 2 is in contact with the inner wall of the limit frame 31 relative to the open end. The in-place detection switch 35 detects that the cheese discharge tray 2 is in place, which triggers the controller 8 to start the tightening cylinder 33. Under the action of the tightening cylinder 33, the telescopic rod of the tightening cylinder 33 extends, driving the tightening block 34 to fit the cheese discharge tray 2 with the inner wall of the limit frame 31 opposite to the notch, thereby achieving the fixation of the cheese discharge tray 2.

[0029] 2. Material collection stage: The rotating motor 41 drives the rotating frame 42 to rotate in the horizontal direction, and then moves the material taking frame 51 to a position facing the cheese placing tray 2; then, the mechanical arm 43 is controlled to move the material taking frame 51 to the top of the cheese placing tray 2; the mechanical arm 43 is then controlled to adjust the material taking frame 51 to a horizontal state, so that the suction port of the vacuum suction cup 52 is vertically downward; then, the mechanical arm 43 is controlled to move the material taking frame 51 downward to a distance of 1 cm from the surface of the cheese placing tray 2, and the push cylinder 61 is started. The telescopic rod extends upward and drives the pushing plate 62 to move upward, so that the pushing block 63 passes through the through hole 23 at the bottom of the discharge trough 21. Under the pushing action of the pushing block 63, the cheese in the discharge trough 21 is pushed upward, and the distance between the cheese and the vacuum suction cup 52 can be further reduced; the suction valve 56 is opened and the vacuum pump 55 is started. Under the adsorption action of negative pressure, the cheese is firmly adsorbed on the vacuum suction cup 52, and then the telescopic rod of the pushing cylinder 61 is retracted to reset the pushing plate 62. At this point, the material taking work is completed.

[0030] 3. Material discharge stage: The robot arm 43 is controlled to move the material picking rack 51 up a certain distance, and then the rotating motor 41 drives the rotating rack 42 to rotate in the horizontal direction, thereby moving the material picking rack 51 to just above the cup mold frame 71 of the blister packaging machine 7; then, the robot arm 43 is controlled to move the material picking rack 51 down to a distance of 0.5 cm from the surface of the cup mold frame 71, and then the vacuum pump 55 and the suction valve 56 are turned off to release the negative pressure adsorption state, and the cheese naturally falls into the blister cup 72 on the cup mold frame 71 under the action of its own weight, and the material discharge work is completed.

[0031] In this embodiment, the number of the feeding slots 21 on the cheese feeding tray 2 is the number of the bubble cups 72 on the three cup mold frames 71. Therefore, one cheese feeding tray 2 can be divided into three feeding areas, and the number and position of the feeding slots 21 in each feeding area correspond to the number and position of the bubble cups 72 on one cup mold frame 71. The feeding mechanism 5 can be used to feed the material three times. Each time the material is fed, the rotating mechanism 4 moves the feeding rack 51 to the top of the corresponding feeding area, so that the vacuum suction cup 52 on the feeding rack 51 corresponds to the feeding slots 21 in the feeding area one by one, and the operation actions in the feeding stage are performed.

[0032] After completing the three material-taking operations, it is necessary to replace a new cheese discharge tray 2 filled with cheese. At this time, first retract the telescopic rod of the tightening cylinder 33, then pull the cheese discharge tray 2 out of the limit frame 31, and then push the new cheese discharge tray 2 into the limit frame 31, and follow the operating actions in the preparation stage.

[0033] Embodiment 2: On the basis of Example 1, this embodiment adds a material tray fixing mechanism 3, and the two material tray fixing mechanisms 3 are respectively arranged on the workbench 1 on both sides of the rotating mechanism 4.

[0034] When taking out the cheese, after all the cheese in the cheese placing tray 2 on one tray fixing mechanism 3 is taken out, the cheese in the cheese placing tray 2 on another tray fixing mechanism 3 is taken out.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
