[0002] With the development of industry and the prevalence of assembly lines, palletizing devices are often used in assembly lines to place the produced items in a certain format.

[0003] In the freezer production line, it is necessary to palletize the freezer bottom package side linings. Usually, a robot is used to palletize the freezer bottom package side linings layer by layer. Since the freezer bottom package side linings (especially the embossed aluminum plates of large models) have poor strength, manual assistance is required to right them when using the robot for automatic palletizing. Otherwise, they are prone to fall inward, which affects the palletizing efficiency and poses a safety hazard. Summary of the Utility Model

[0022] After the robot 5 grabs the U-shaped inner liner of the bottom and side of the freezer and automatically transfers it to the palletizing truck 1, the progressive pulling-back mechanism 4 drives the pneumatic material supporting mechanism 3 to straighten the inner liner of the bottom and side of the freezer placed on the palletizing truck 1, preventing the inner liner of the bottom and side of the freezer from tipping over after palletizing, enabling the robot 5 to continuously load and palletize, with the whole process being fully automated and without manual assistance.

[0023] Please refer to Figure 3 As shown, in this embodiment, the position adjustment mechanism 2 at least includes a base 21, a first servo motor 22, a ball screw pair 23, a first linear guide pair 24, and a support plate 25.

A first linear guide pair 24 is fixedly installed between the two bases 21 through the support plate 25. The ball screw pair 23 is rotatably installed above the first linear guide pair 24 through bearing seats at both ends. The rotating shaft of the first servo motor 22 is fixedly connected to one end of the ball screw pair 23. The first servo motor 22 is used to drive the ball screw pair 23 to rotate, and the front and rear positions of the progressive pulling-back mechanism 4 and the pneumatic material supporting mechanism 3 on the palletizing truck 1 are adjusted by the rotation of the ball screw pair 23.

[0024] Please refer to Figure 3 As shown, in this embodiment, the progressive pulling-back mechanism 4 includes a machine base 41, a cross plate 42, a driving component, and a bracket 43. Among them, the bottom end of the machine base 41 is threadedly sleeved on the outer periphery of the ball screw pair 23, and the machine base 41 is slidably engaged with the first linear guide pair 24, so that when the ball screw pair 23 rotates, it can drive the machine base 41 to reciprocate on the first linear guide pair 24. The cross plate 42 is fixedly installed at one end of the machine base 41 away from the ball screw pair 23. The driving component is arranged on the cross plate 42. The bracket 43 is arranged on the driving component. The pneumatic material supporting mechanism 3 is arranged on the bracket 43, so that the driving component, the bracket 43, and the pneumatic material supporting mechanism 3 all reciprocate synchronously with the machine base 41. The driving component is used to drive the bracket 43 to drive the pneumatic material supporting mechanism 3 to reciprocate on the cross plate 42.

[0025] Please refer to Figure 4 As shown, in this embodiment, the driving component includes a second linear guide pair 44, a mounting plate 45, a second servo motor 46, a gear 47, and a rack 48.

The output shaft of the second servo motor 46 drives the gear 47 to rotate. The rotation of the gear 47 drives the mounting plate 45 to slide along the second linear guide pair 44 in cooperation with the rack 48. The bracket 43 and the pneumatic material supporting mechanism 3 move synchronously with the mounting plate 45.

[0026] Each time the robot 5 places the lining on the side of the bottom bag of the freezer, the progressive pull-back mechanism 4 completes a forward and pull-back cycle action once.

[0027] See also Figure 3 As shown, in this embodiment, the pneumatic material supporting mechanism 3 includes a lifting cylinder 31 fixedly mounted on a bracket 43, the piston rod of the lifting cylinder 31 is fixedly mounted with a connecting block 32, a guide column 33 is fixedly inserted on the connecting block 32, and a straightening block 34 is fixedly connected to the bottom end of the guide column 33. The piston rod of the lifting cylinder 31 drives the connecting block 32 to move up and down, and the connecting block 32 drives the guide column 33 and the straightening block 34 to move up and down synchronously.

[0028] Furthermore, the pneumatic material supporting mechanism 3 also includes a support seat 35 and a guide sleeve 36. The support seat 35 is fixedly mounted on the bracket 43, the guide sleeve 36 is integrally arranged on the support seat 35, and the guide sleeve 36 is movably sleeved on the outer periphery of the guide column 33. Under the limitation of the guide sleeve 36, the lifting and lowering movement of the guide column 33 is smoother and does not shake.

[0029] Each time the robot 5 places the lining on the side of the bottom bag of the freezer, the pneumatic material supporting mechanism 3 completes a lifting and lowering cycle.

[0030] In summary, the utility model provides an automatic stacking and straightening device for the lining of a freezer, which combines a position adjustment mechanism 2, a pneumatic material supporting mechanism 3 and a progressive pull-back mechanism 4 into one device. The position adjustment mechanism 2 can adjust the positions of the pneumatic material supporting mechanism 3 and the progressive pull-back mechanism 4 according to the different sizes of the lining on the bottom bag side of the freezer. Each time the robot 5 puts the lining on the bottom bag side of the freezer, the pneumatic material supporting mechanism 3 completes a lifting and lowering cycle, and then the progressive pull-back mechanism 4 completes a forward and pull-back cycle. With the joint cooperation of the pneumatic material supporting mechanism 3 and the progressive pull-back mechanism 4, the lining on the bottom bag side of the freezer can be assisted in straightening when the robot 5 automatically stacks, so that the lining on the bottom bag side of the freezer does not fall over when the robot 5 automatically stacks, so that the robot 5 can continuously put out materials and stack, and the whole process is automated without manual assistance, thereby improving stacking efficiency and reducing safety risks.
