The stock bin 60 in this embodiment includes a three-dimensional material rack 61, a transfer mechanism 62 and a second height adjusting mechanism 63, wherein the three-dimensional material rack 61 forms a plurality of layers of stock spaces distributed from top to bottom by a material supporting unit 612, and each layer of stock space is capable of storing one or more aluminum profiles 70.

The following describes the working principle of the stock house 60 during feeding and discharging, respectively:
As shown in fig. 7, when the aluminum profile 70 is required to be fed, the second height adjusting mechanism 63 drives the transfer mechanism 62 to rise, so that the loading surface of the transfer mechanism 62 is higher than the loading surface of the feeding shaft 12. Then the lowest material supporting unit 612 descends to enable the aluminum profile 70 to fall to the feeding end (the end adjacent to the material supporting rod) of the transferring mechanism 62, and the transferring mechanism 62 is started to drive the aluminum profile 70 to move towards the feeding rotating shaft 12. When the aluminum profile 70 moves to the position right above the feeding rotating shaft 12, the second height adjusting mechanism 63 drives the transferring mechanism 62 to descend again, so that the aluminum profile 70 falls onto the feeding rotating shaft 12, and the feeding rotating shaft 12 drives the aluminum profile 70 to move towards the processing table 20, so that feeding is completed. After the aluminum profiles 70 are completely stacked on the lower material supporting unit 612, the lifting mechanism 613 drives the material supporting unit 612 to descend by one material level, so that the material supporting unit 612 positioned on the upper layer can perform the discharging of the aluminum profiles 70.
As shown in fig. 8, when the blanking of the aluminum profile 70 is required, the blanking assembly 50 conveys the aluminum profile 70 to the feeding end (the end adjacent to the blanking rotary shaft 52) of the transfer mechanism 62, and then the second height adjusting mechanism 63 drives the transfer mechanism 62 to ascend, and the transfer mechanism 62 can lift the aluminum profile 70. Then the transfer mechanism 62 conveys the aluminum profile 70 to the material supporting unit 612, and when the aluminum profile 70 reaches a proper position above the material supporting unit 612, the second height adjusting mechanism 63 drives the transfer mechanism 62 to descend so that the aluminum profile 70 falls onto the material supporting rod. When the upper material supporting unit 612 is fully stacked with the aluminum profiles 70, the lifting mechanism 613 drives the material supporting unit 612 to lift a material level, so that the lower material supporting unit 612 can stack the aluminum profiles 70. The second height adjusting mechanism 63 may be a vertically arranged hydraulic cylinder, and the transferring mechanism 62 is disposed at a lifting end of the hydraulic cylinder.
The transfer mechanism 62 may be a belt conveyor, a chain conveyor, or other conveying devices, and a plurality of aluminum profiles 70 may be simultaneously conveyed on the transfer mechanism 62. During the feeding or discharging of the aluminum profile 70, the height of the material supporting unit 612 can be finely adjusted through the lifting mechanism 613 so as to be matched with the transferring assembly to enable the aluminum profile 70 to be transferred smoothly.
In this embodiment, by providing two stock bins 60, the delivery and storage stacking of the aluminum profiles 70 can be completed, and the automation degree is higher.

In this embodiment, the transferring mechanism 62 includes a first inclined transferring unit 621 and a second horizontal transferring unit 622, where the first transferring unit 621 and the second transferring unit 622 may be a belt conveyor integrally connected to each other, or may be two independent conveying structures, and a discharging end of the first transferring unit 621 is connected to a feeding end of the second transferring unit 622. When a plurality of aluminum profiles 70 are stacked on the material supporting unit 612, the inclined first transfer unit 621 can be preferentially contacted with the aluminum profile 70 positioned at the outermost side (i.e., the side adjacent to the material loading assembly 10), so that the first transfer unit 621 only conveys one aluminum profile 70 at a time, thereby facilitating the realization of one-by-one delivery and one-by-one storage of the aluminum profiles 70.
