After being laid flat, the rack connecting rod 4 can be connected with another rack cart (part stacking rack).

[0042] The working process of the utility model is as follows: ​​​​​

[0043] The parts storage rack is divided into several layers, and the parts of each layer are taken and placed one by one.

[0044] When placing the bottom layer of materials (parts 11), the support block mechanism 7 does not need to be provided with an empty position 7-1, and the lowermost support block mechanism 7 is maintained in the standby position 7-2 by the standby position limiting pin 10. At this time, all the bottom layer support block mechanisms 7 are in the standby position 7-2, and all the upper layer support block mechanisms 7 are in the empty position 7-1, reaching the condition for placing the second layer of parts;

[0045] After placing the bottom layer of parts 11, the bottom layer support block mechanism 7 is affected by the weight of the parts, at this time the support plate 74 is horizontal and drops to the lowest point, and the top hook 71 is inclined to the highest point. In the process of the bottom layer support block mechanism 7 reaching the placement position 7-3, the bottom layer top hook 71 gradually lifts the second last layer support block mechanism 7 to the standby position 7-2. At this time, all the bottom layer support block mechanisms 7 are in the placement position 7-3, all the second last layer support block mechanisms 7 are in the standby position 7-2, and all the upper layer support block mechanisms 7 are in the empty position 7-1, again reaching the condition for placing parts;

[0046] The above steps are continuously cycled until the uppermost layer of parts 11 is placed. At this time, all the uppermost layer support block mechanisms 7 are affected by the force of the next layer support block mechanism 7, and are in the standby position 7-2, and can place the uppermost layer of parts 11;

[0047] After placing the uppermost layer of parts 11, the uppermost layer support block mechanism 7 is affected by the weight of the parts and is in the placement position 7-3, and the part placement is completed, as shown in Figure 1 .

[0048] When taking the first layer of parts 11, the uppermost layer support block mechanism 7 is affected by the weight of the parts and is in the placement position 7-3, and after the parts 11 are taken away, the uppermost layer support block mechanism 7 is affected by the weight and returns to the standby position 7-2. At this time, all the uppermost layer support block mechanisms 7 are in the standby position 7-2, and all the lower layer support block mechanisms 7 are in the placement position 7-3, reaching the condition for taking parts;

[0049] When taking the second layer of parts 11, as the parts 11 are taken out, the second layer support block mechanism 7 gradually reduces the weight of the parts and gradually increases the weight of the self, and gradually swings from the placement position 7-3 to the standby position 7-2. While the second layer support block mechanism 7 swings, the second layer top hook 71 gradually falls, and the first layer support block mechanism 7 lifted by it is gradually affected by the weight and gradually falls, and gradually swings from the standby position 7-2 to the empty position 7-1. At this time, the first layer support block mechanism 7 is in the empty position 7-1, the second layer support block mechanism 7 is in the standby position 7-2, and all the lower layer support block mechanisms 7 are in the placement position 7-3, again reaching the condition for taking parts;

[0050] The above steps are continuously cycled until the lowest layer of parts 11 is grabbed. At this time, all the lowest layer of block mechanisms 7 are in the placement position 7-3, the next layer of block mechanisms 7 are in the standby position 7-2, and all the upper layer of block mechanisms 7 are in the empty position 7-1, so that the lowest layer of parts 11 can be grabbed;

[0051] After the lowest layer of parts 11 is taken away, the lowest layer of block mechanisms 7 is affected by gravity and gradually swings from the placement position 7-3 to the standby position 7-2. Due to the action of the bottom layer of standby position limiting pins 10, the lowest layer of block mechanisms 7 stops moving after reaching the standby position 7-2, and the taking part ends.

[0052] For different vehicle roof covers, the position of the rack stand 1 relative to the mounting plate 12 can be adjusted by the column adjusting mechanism 2, so as to adapt to the size of the roof cover of different vehicles.

[0053] For the automatic line, a sensor can be added to detect the position of the part, further increasing the reliability of the utility model, so that it can adapt to the robot gripper for taking and placing parts, and be flexibly introduced into the automatic line.

[0054] Further, this mechanism can be extended to other special-shaped products after size adjustment and cooperation with appropriate limiting mechanisms, and can be made into a rack of different products in the form of a universal self-return mechanism.

[0055] Compared with the prior art, the utility model can save the manual operation content of the rack mechanism return, and reduce the post demand. At the same time, the success rate and turnover efficiency of the mechanism are better than those of the background technology, and the production off-line rate is reduced. In addition, the utility model integrates the fragmented time of employees, so that the work of this post can be completed by the employees of the surrounding posts, and the utilization rate of employees is improved.

[0056] It can be understood that, for those skilled in the art, equivalent replacement or change of the technical scheme and utility model concept of the utility model should belong to the protection range of the claims attached to the utility model.
