[0029] The palletizing device is used for composite processing of profiles, and is suitable for profiles of C-shaped and U-shaped structures, such as C-shaped steel and U-shaped steel. The opening of the profile facing upward is the positive profile 1, and the opening of the profile facing downward is the reverse profile 2. The palletizing device includes a feeding mechanism, a supporting mechanism, a receiving mechanism, a transport mechanism, and a discharging mechanism. The feeding mechanism is horizontally arranged and is used for feeding and conveying profiles. The supporting mechanism is located on the left side of the feeding mechanism to support the positive profile 1.

The transport mechanism is movably arranged above the supporting mechanism and the receiving mechanism to transport multiple profiles located at the supporting mechanism and the receiving mechanism in batches. The discharging mechanism is arranged side by side with the supporting mechanism and the receiving mechanism to receive the profiles from the transport mechanism for discharging and conveying the profiles.

[0030] The support mechanism includes a support plate 3 and a baffle 4. The support plate 3 is arranged horizontally, that is, placed in the left-right direction, and can be flush with the feed conveyor belt 8, and is arranged at intervals and evenly distributed in the front-back direction. The baffle 4 is located on the left side of the support plate 3, is arranged vertically, and extends upward from the surface of the support plate 3.

The receiving plate 5 is arranged horizontally, that is, placed in the left-right direction, and can be flush with the feed conveyor belt 8, and arranged at intervals and evenly distributed in the front-back direction. The vertical plate 6 is located on the right side of the receiving plate 5, is vertically arranged, and extends upward from the surface of the receiving plate 5.

[0032] The feeding mechanism includes a feeding conveyor belt 8, a limiting plate 9, a flap 10, and a clamping block 11. The feeding conveyor belt 8 is arranged longitudinally, that is, arranged along the front-to-back direction, with the rear side of the feeding conveyor belt 8 as the starting end and the front side as the end. The limiting plate 9 is located at the end of the feeding conveyor belt 8, and is arranged vertically, extending upward from the surface of the feeding conveyor belt 8, and the extending height is greater than or equal to the height of the profile, which plays a role in blocking and limiting the end of the profile.

The flap 10 is located on the right side of the feeding conveyor belt 8, and is arranged to rotate vertically. Each rotation stroke is 180 degrees, which plays a role in flipping the profile. The clamping block 11 is located on the right side of the feeding conveyor belt 8, and is arranged to slide along the left and right directions.

[0033] The profile is placed in the feed conveyor 8 in sequence with the opening facing upward. The feed conveyor 8 transports the individual profiles in sequence until the end of the profile contacts the limit plate 9. For ease of understanding, the profiles transported in sequence are referred to as the first profile, the second profile, and so on. First, the clamping block 11 slides to the left, and the first profile moves to the left under the push of the clamping block 11, enters the support plate 3 from the feed conveyor 8, until it contacts the baffle 4, and the feed conveyor 8 docks with the support plate 3. Then, the clamping block 11 is reset to the right, and the second profile moves to the right under the push of the clamping block 11, enters the flap 10 from the feed conveyor 8, and the flap 10 rotates vertically 180 degrees. The push block 7 slides to the right, and the second profile moves to the right under the push of the push block 7, and enters the receiving plate 5 from the flap 10, until it contacts the vertical plate 6, and the feed conveyor 8 docks with the support plate 3 through the flap 10.

The transport platform 12 moves to the top of the support plate 3 and the receiving plate 5, and the lifting plate 13 moves downward until the electromagnet 14 conflicts with the profile. After the electromagnet 14 is energized, it magnetically attracts the profile and transports it to a shelf, a conveyor belt, and other locations for storage.

[0035] The utility model is used for composite processing of profiles and for stacking profiles with C-shaped and U-shaped structures.

[0036] First, with the opening facing upward as the positive direction, multiple positive profiles 1 are sequentially placed into the feed conveyor 8 , and the feed conveyor 8 transports the individual profiles sequentially until the end of the profile contacts the limit plate 9 .

[0037] Then, the clamping block 11 moves to the left, pushing the first profile into the support plate 3 until it contacts the baffle plate 4, and the first profile is placed in the forward direction.

The profiles on the support plate 3 are all placed in the forward direction, and the profiles on the receiving plate 5 are all placed in the reverse direction. Through the movement of the transport platform 12, the lifting plate 13, and the adsorption of the electromagnet 14, the forward profile 1 is placed at the bottom, and the reverse profile 2 is stacked on the top, completing the profile stacking process.

[0039] During this process, it can achieve the effects of up and down placement, reverse stacking, and mutual interlocking, thereby improving space utilization and stacking stability. Moreover, the stacking process is automated and does not require manual intervention, effectively improving production efficiency.

The clamping block 21 is connected to a torsion spring that provides a reset function. The clamping block 21 corresponds to the opening position of the groove 16. After the flap 10 rotates 180 degrees, the profile is located in the groove 16 and docks with the receiving plate 5.
