Technical Field

[0001] This utility model relates to palletizing equipment, and more particularly to a palletizing mechanism for greenhouse support profiles. Background Technology

[0002] With the development of automation, palletizing equipment has become a crucial component of automated production lines, especially for linear production lines. After linear profiles are formed, they often need to be stored in a specific order to save space. Currently, palletizing equipment needs to be used in conjunction with lifting equipment. The lifting equipment stacks the profiles, and finally, a packaging machine packs them. For a type of greenhouse support profile with an opening at the bottom, direct stacking not only occupies a large amount of space, resulting in a large pallet volume, but also makes packaging difficult. Summary of the Invention

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] like Figures 1 to 3 As shown, the greenhouse support profile stacking mechanism includes a feeding and turning device 100, a stacking transfer device 200 located on one side of the feeding and turning device 100, and a lifting device 300 located above the feeding and turning device 100 and the stacking transfer device 200. The feeding and turning device 100 is used to position and turn the fed profile 180°. The stacking transfer device 200 is used to assist in stacking and transferring. The lifting device 300 is used to clamp the profile and move it from the feeding and turning device 100 to the stacking transfer device 200.

[0019] After the profile is shaped and cut to the predetermined length, Figure 6 The material enters the feeding and turning device 100 in the state shown, where it is flipped 180° and inverted, with the opening of the profile facing upwards. Then, it is clamped and moved by the lifting device 300 to the stacking transfer device 200, with multiple profiles arranged in a row with their openings facing upwards. Next, the cut profiles are still... Figure 6 The state shown indicates that the material enters the feeding and turning device 100. At this time, the feeding and turning device 100 does not turn the material. The lifting device 300 directly clamps and moves the profile to the stacking transfer device 200 and inserts it into the opening of the inverted profile. Multiple profiles are inserted and arranged in a row. See the state below. Figure 7 Repeat the above two steps of inserting one row of inverted profiles and one row of upright profiles. Stop when the stacking reaches the required height. The stacking transfer device 200 moves the stacked multi-layer profiles away from the feeding and turning device 100 and transports them to the packaging device for packaging. After packaging, the profiles are transported to the designated area for stacking. The stacking transfer device 200 is reset and the stacking continues.

[0020] See Figures 1 to 4The feeding and turning device 100 includes a feeding rack 101 and a feeding conveying device disposed on the feeding rack 101. The feeding rack 101 is provided with a telescopic flat pushing device and a lifting blocking device on the left and right sides of the feeding conveying device. The lifting blocking device is close to the stacking transfer device 200. The feeding rack 101 is also provided with a rotary clamping device for turning the profile clamp outward by 180° between the lifting blocking device and the stacking transfer device 200. Before the profile enters the feeding conveyor, the lifting stop device rises to correspond to the height of the profile. After the profile enters the feeding conveyor, the telescopic pusher extends to push one side of the profile, so that the other side of the profile abuts against the lifting stop device. At this time, the lifting device 300 can directly clamp and move the upright profile with the opening facing downward. When the profile needs to be flipped, before the profile enters the feeding conveyor, the lifting stop device descends below the height of the profile. After the profile enters the feeding conveyor, the telescopic pusher extends to push one side of the profile, so that the other side of the profile abuts against the rotary clamping device. The rotary clamping device clamps the upright profile and flips it outward by 180°, turning it into an inverted profile. At this time, the lifting device 300 clamps and moves the inverted profile.

[0021] The feeding and conveying device includes multiple feeding rollers 102 arranged along the profile conveying direction. The feeding rollers 102 are driven by a chain, and the power transmission is achieved by a motor through a sprocket and the chain. This is existing technology and will not be described in detail here.

[0022] The telescopic pushing device includes multiple telescopic pushing cylinders 103 arranged along the length of the profile. The cylinder body of each telescopic pushing cylinder 103 is fixed to the feeding frame 101 by a bracket. The telescopic end of each telescopic pushing cylinder 103 is horizontally arranged and connected to a telescopic pushing block 104 that can push the profile on the feeding conveyor towards the rotary clamping device. The telescopic pushing block 104 is made of rubber. The extension and retraction of the telescopic pushing cylinder 103 drives the telescopic pushing block 104 to reciprocate, thereby pushing the profile to move horizontally.

[0023] The lifting and stopping device includes multiple telescopic cylinders 105 arranged along the length of the profile. The cylinder body of each telescopic cylinder 105 is fixed to the feeding frame 101 by a bracket. The telescopic end of each telescopic cylinder 105 is vertically arranged and rotatably connected to a lifting and stopping roller 106. The rotation axis of the lifting and stopping roller 106 is vertically arranged. The extension and retraction of the telescopic cylinders 105 drive the lifting and stopping roller 106 to rise and fall. After rising, the height of the lifting and stopping roller 106 corresponds to the height of the profile, which can limit and abut the profile. After falling, the height of the lifting and stopping roller 106 is lower than the height of the profile, which can avoid the profile and allow it to move to the rotary clamping device.

[0024] The rotary clamping device includes a flipping shaft 107 parallel to the length direction of the profile and a flipping power structure that drives the flipping shaft 107 to rotate. The flipping shaft 107 is rotatably mounted on the feed rack 101 via a bearing seat. Multiple flipping frames 108 are fixed on the flipping shaft 107. Each flipping frame 108 is correspondingly provided with a rotary clamping cylinder 109. The cylinder body of the rotary clamping cylinder 109 is located below the profile. The feed rack 101 is correspondingly provided with a profile shelf 110 at the flipped position. The flipping power structure can drive the flipping shaft 107 to rotate so that the rotary clamping cylinder 109 flips the clamped profile 180° into the profile shelf 110. When the profile is pushed against the flipping frame 108 by the telescopic pushing device, it stops. The bottom surface of the profile is supported on the cylinder body of the rotary clamping cylinder 109. The rotary clamping cylinder 109 clamps the stopped profile. Then the flipping power structure is activated, driving the flipping shaft 107 to rotate, so that the rotary clamping cylinder 109 drives the clamped profile to flip outward by 180°. The profile is placed on the profile shelf 110, waiting for the lifting device 300 to move to the stacking transfer device 200. Then the rotary clamping cylinder 109 releases the profile, and the flipping power structure rotates 180° in the opposite direction to reset, waiting for the next profile to be flipped.

[0025] The flipping power structure includes a motor. Both the output end of the motor and the flipping shaft 107 are equipped with sprockets. The two sprockets are connected by a chain for power transmission. The operation of the motor controls the rotation of the flipping shaft 107, thereby driving the flipping frame 108, the rotary clamping cylinder 109 and the profile clamped thereon to flip 180°.

[0026] The cylinder body of the rotary clamping cylinder 109 is fixed to the tilting frame 108, and the surface of the cylinder body of the rotary clamping cylinder 109 is at the same height as the feed roller 102, allowing the profile to be directly pushed onto the surface of the rotary clamping cylinder 109. The telescopic end pressure arm 111 of the rotary clamping cylinder 109 can be laid flat to release the profile or placed vertically to clamp the profile. The telescopic end of the rotary clamping cylinder 109 can extend and retract. When extended, the telescopic end pressure arm 111 rotates to lay flat to release the profile; when retracted, the telescopic end pressure arm 111 rotates to stand vertically to clamp the profile. The rotary clamping cylinder 109 is prior art, and its specific working principle will not be described in detail.

[0027] See Figure 1 , Figure 2 , Figure 3 and Figure 5 The palletizing transfer device 200 includes a discharge bracket 201 and a palletizing transfer trolley 202 slidably mounted on the discharge bracket 201, which can be close to or away from the feeding and turning device 100. The discharge bracket 201 has multiple fixed pallets 203 located above the palletizing transfer trolley 202 on the side closest to the feeding and turning device 100. The palletizing transfer trolley 202 is equipped with a lifting pallet device that can be higher or lower than the fixed pallets 203. The palletizing transfer trolley 202 also has a rotation limiting device that can place the profile horizontally or vertically on the left and right sides. When the profile is palletized, the palletizing transfer trolley 202 is located on one side of the feeding and turning device 100, and the lifting pallet device is lowered while the rotation limiting device is upright. At this time, the profile is transported by the lifting device 300, placed on the fixed pallets 203, and positioned between the rotation limiting devices, thus being limited by the rotation limiting devices. (See attached diagram). Figure 1 Once the profiles are stacked to the required height, the lifting pallet device rises, lifting the profiles from the fixed pallet 203. Then, the palletizing transfer trolley 202 moves to the other side, moving the stacked profiles closer to the packaging device. After packaging, the rotating limiting device rotates and lays flat to avoid obstruction, and the profiles are transported to a designated area for stacking. Then, the lifting pallet device descends below the fixed pallet 203, while the rotating limiting device remains flat. The palletizing transfer trolley 202 moves towards the feeding and turning device 100. During this process, the lifting device 300 continues to transport the profiles towards the fixed pallet 203. After the lifting pallet device and the rotating limiting device pass under the fixed pallet 203, the rotating limiting device switches from flat to upright to assist in the stacking of profiles. This cycle repeats, facilitating the smooth stacking and packaging process.

[0028] The discharge tray 201 is provided with at least two travel guide rails 204, and the bottom end of the palletizing transfer trolley 202 is provided with multiple travel wheels that slide in cooperation with the travel guide rails 204. A travel power structure for driving the palletizing transfer trolley 202 to reciprocate is also provided between the discharge tray 201 and the palletizing transfer trolley 202. The travel power structure can be a gear and rack combination or a sprocket and chain combination.

[0029] See Figure 4 The lifting pallet device includes multiple pallet telescopic cylinders 205 arranged along the length of the profile. The cylinder body of each pallet telescopic cylinder 205 is fixed to the stacking transfer trolley 202 by a bracket. The telescopic end of each pallet telescopic cylinder 205 is vertically arranged and fixed with a lifting pallet 206. By extending and retracting the pallet telescopic cylinders 205, the lifting pallet 206 is driven to rise and fall. When the lifting pallet 206 falls below the height of the fixed pallet 203, the profile is placed on the fixed pallet 203 for stacking. After stacking is completed, the lifting pallet 206 rises above the fixed pallet 203, lifting the profile away from the fixed pallet 203, facilitating the movement of the stacking transfer trolley 202.

[0030] See Figure 4 The rotation limiting device includes a horizontal rotating shaft 207 perpendicular to the length direction of the profile and a rotational power structure that drives the horizontal rotating shaft 207 to rotate. The horizontal rotating shaft 207 is rotatably connected to the palletizing transfer trolley 202. Limiting rods 208 are fixed to both ends of the horizontal rotating shaft 207. The rotational power structure can drive the horizontal rotating shaft 207 to rotate, allowing the limiting rods 208 to switch 90° between flat and upright positions. The width between the two limiting rods 208 is slightly larger than the required width for palletizing, facilitating left and right width positioning during palletizing. The height of the horizontal rotating shaft 207 is lower than the minimum height of the lifting pallet 206 to avoid interference. When palletizing is required, the rotational power structure activates, driving the horizontal rotating shaft 207 to rotate, causing the two limiting rods 208 to rotate to an upright position, i.e. Figure 5 In the middle state, the left and right limit bars 208 work together to stack the profiles between the two limit bars 208; after the profiles are packaged, the rotary power structure is activated, driving the horizontal rotating shaft 207 to rotate 90° in the opposite direction, so that the two limit bars 208 rotate to a flat position to avoid collision.

[0031] See Figure 4The rotating power structure includes a rotating support 209 fixed to the surface of the horizontal rotating shaft 207. A rotating telescopic cylinder 210 is provided between the rotating support 209 and the palletizing transfer trolley 202. One end of the rotating telescopic cylinder 210 is connected to the palletizing transfer trolley 202 through a hinge support, and the other end of the rotating telescopic cylinder 210 is connected to the rotating support 209 through a hinge support. By extending and shortening the rotating telescopic cylinder 210, the rotating support 209 is pushed and pulled, causing the horizontal rotating shaft 207 to rotate.

[0032] The lifting device 300 includes a multi-axis truss and lifting claws installed on the multi-axis truss. The lifting claws can be magnetic claws or opening and closing claws. The lifting claws can be lifted, moved, and translated under the drive of the multi-axis truss. This is existing technology, and its specific structure is not shown in the figure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
