Description

Technical Field

[0001] This invention relates to the field of palletizing machine technology, and in particular to an automatic palletizing and spacer placement machine for channel steel. Background Technology

[0002] In industrial production, channel steel is an important structural material, and its storage and pre-transport palletizing process is essential. Traditional channel steel palletizing mainly relies on manual operation, where workers need to move each channel steel piece to a designated location and stack them in layers according to requirements. This manual palletizing method has obvious technical drawbacks and low palletizing efficiency.

[0003] While existing automated palletizing equipment has solved the efficiency problem to some extent, most of it is designed for standardized boxes or bagged materials. For special profiles like channel steel, which are long, narrow, and prone to rolling, it often suffers from the following technical shortcomings:

[0004] Limited functionality: Most equipment can only complete palletizing operations and cannot simultaneously achieve automatic placement of spacers, still requiring manual intervention to complete the spacer laying.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example: This example discloses an automatic palletizing and spacer placement machine for channel steel, including: a base 1, a palletizing mechanism 3, a spacer placement mechanism 5, and a palletizing frame 6. The palletizing mechanism 3 is used to stack channel steel on the palletizing frame 6. After each layer is stacked, the spacer placement mechanism 5 transports the spacers to be laid on the surface of the channel steel, so that spacers are placed between the upper and lower layers of channel steel. A pair of frames 2 are fixedly connected to the base 1. A drive mechanism for moving the palletizing mechanism 3 is installed on the frame 2. The drive mechanism drives the palletizing mechanism 3 to move back and forth to stack the channel steel.

[0033] Preferably, the driving mechanism includes a first drive motor 204, a first rotating rod 201, and a first transmission chain 203. The first drive motor 204 is mounted on the frame 2, and the first rotating rod 201 is rotatably connected between the two frames 2. The first drive motor 204 is used to drive the first rotating rod 201 to rotate, and a first transmission wheel 202 that is rotatably connected to the surface of the first rotating rod 201 is fixedly connected to the first transmission chain 203. The first transmission chain 203 can be a chain, and the first transmission wheel 202 can be a sprocket. The first drive motor 204 drives the two first rotating rods 201 to rotate, thereby driving the first transmission chain 203 to move. When the first transmission chain 203 moves, it drives the palletizing mechanism 3 to reciprocate.

[0034] like Figures 2-3 As shown, the palletizing mechanism 3 includes a movable frame 301 and a lifting frame 302. Both ends of the movable frame 301 are fixedly installed with first clamps 305 that are fixedly connected to the first transmission chain 203, so that the first transmission chain 203 drives the palletizing mechanism 3 to move when it moves. At the same time, the frame 2 is equipped with a slide rail 205 that is slidably connected to the movable frame 301. The movable frame 301 is equipped with a lifting cylinder 303 for driving the lifting frame 302 to move up and down. The lifting frame 302 is fixedly connected to the piston rod of the lifting cylinder 303, and the lifting frame 302 is fixedly connected with a guide rod 304 that is slidably connected to the movable frame 301 to ensure the stability of the lifting frame 302. The lifting frame 302 is equipped with multiple picking and placing mechanisms 4 for picking and placing channel steel. In this embodiment, the number of picking and placing mechanisms 4 is three to ensure the stability of picking and placing channel steel.

[0035] like Figure 5As shown, the pick-and-place mechanism 4 includes a connecting seat 41 fixedly connected to the movable frame 301. A rotating seat 42 is rotatably connected to the connecting seat 41. A top plate 44 and a bottom plate 45 are respectively installed on the upper and lower sides of the rotating seat 42. Multiple fixing rods 49 are fixedly connected between the top plate 44 and the bottom plate 45. The fixing rods 49 are movably connected to the rotating seat 42, and multiple compression springs 47 are connected to the surface of the fixing rods 49. The compression springs 47 are located between the rotating seat 42 and the top plate 44 and the bottom plate 45. An electromagnet 46 is fixedly connected to the surface of the bottom plate 45 for picking up the channel steel. A rotary motor 306 is fixedly installed on the lifting frame 302. A rotating shaft 307 is connected to the rotary motor 306 and is fixedly connected to the rotating seat 42. Multiple locking mechanisms 43 for locking the rotating seat 42 are installed on the surface of the rotating shaft 307. In practice: The moving frame 301, driven by the drive mechanism, moves the entire pick-and-place mechanism 4 to directly above the channel steel to be picked up; according to the stacking requirements, the rotary motor 306 starts, driving the rotating seat 42 via the rotating shaft 307, which in turn drives the entire adsorption unit composed of the top plate 44, bottom plate 45, and electromagnet 46 to rotate, thereby adsorbing the channel steel directly above or below to meet the requirements of staggered or specific placement in the stacking; the lifting cylinder 303 operates, pushing the lifting frame 302 to slide downwards along the guide rod 304, causing the electromagnet 46 on the bottom plate 45 to contact or rest against... Near the surface of the channel steel; the electromagnet 46 is energized, generating strong magnetism, firmly attracting multiple channel steels; during the descent and subsequent movement, the compression spring 47 between the top plate 44 and the bottom plate 45 provides elastic buffering through the fixing rod 49, which can effectively absorb the impact force at the moment of contact and prevent damage to the surface of the channel steel or the equipment; in the locked state, the lifting frame 302 is raised, and the moving frame 301 moves, transporting the channel steel to the target position above the stacking frame 6; the lifting frame 302 descends again, and after placing the channel steel in the designated position, the electromagnet 46 is de-energized, the magnetism disappears, and the channel steel is accurately released.

[0036] like Figures 6-7As shown, the locking mechanism 43 includes a rotating seat 431, a sliding seat 432, and a fixed seat 433. The sliding seat 432 is located between the rotating seat 431 and the fixed seat 433. The rotating seat 431 is rotatably connected to the rotating shaft 307, and a hinge seat 4313 is provided on the surface of the rotating seat 431. A connecting rod 48 is hinged between the hinge seat 4313 and the top plate 44. The sliding seat 432 is slidably connected to the surface of the rotating shaft 307, and the rotating shaft 307 rotates, causing the sliding seat 432 to rotate together. The fixed seat 433 is fixedly installed on the inner side of the connecting seat 41, and the fixed seat 433 remains stationary when the rotating shaft 307 rotates. A pair of slots 4332 are symmetrically provided on the surface of the fixed seat 433, and a locking block 4322 that engages with the slots 4332 is provided on the surface of the sliding seat 432. A pressing block 4311 is provided on the surface of the rotating seat 431 for pressing the sliding seat 432 to slide. Both ends of the pressing block 4311 are provided with inclined surface structures 4312. The sliding seat 432 has an extrusion groove 4321 on its surface that matches the shape of the extrusion block 4311. When the electromagnet 46 attracts the channel steel, the channel steel is located below the electromagnet 46. The top plate 44 is lowered by the gravity of the channel steel, causing the rotating seat 431 to rotate. When the rotating seat 431 rotates, it causes the extrusion block 4311 to slide in the extrusion groove 4321, thereby extruding the sliding seat 432 and causing the sliding seat 432 to move closer to the fixed seat 433. The locking block 4322 engages in the slot 4332, thereby locking the rotating shaft 307 and the rotating seat 42, ensuring that the electromagnet 46 can remain stable after attracting the channel steel. Similarly, when the rotating seat 42 rotates 180° and the electromagnet 46 attracts the channel steel directly below it, the channel steel is above the electromagnet 46, and the top plate 44 is also lowered by the gravity of the channel steel, causing the locking block 4322 to engage in the slot 4332, locking the rotating shaft 307 and the rotating seat 42.

[0037] Preferably, a plurality of reset elastic elements 4331 are fixedly installed on the surface of the fixed seat 433 for resetting the sliding seat 432. When the channel steel is separated from the electromagnet 46, the top plate 44 and the bottom plate 45 return to their original positions, causing the rotating seat 431 to rotate in the opposite direction to its original position. Under the elastic force of the reset elastic elements 4331, the sliding seat 432 slides to a position close to the rotating seat 431, so that the locking block 4322 separates from the locking groove 4332. At this time, the pressing block 4311 is in the pressing groove 4321.

[0038] Preferably, a lifting motor 206 is installed on the frame 2, and a lead screw 207 is installed on the shaft of the lifting motor 206 to drive the spacer placement mechanism 5 to lift. A guide rail 101 that is slidably connected to the spacer placement mechanism 5 is fixedly installed on the base 1. As the channel steel is stacked, the spacer placement mechanism 5 is driven to rise synchronously by the lifting motor 206, so that the spacer can be laid on the channel steel.

[0039] like Figures 8-9As shown, the spacer placement mechanism 5 includes a base frame 51 and a lifting bracket 53. The base frame 51 is slidably connected to the guide rail 101. The spacer is placed on the lifting bracket 53. A pair of fixed brackets 510 are symmetrically fixedly connected to the base frame 51. A pair of second rotating rods 54 are rotatably connected between the two fixed brackets 510. The two second rotating rods 54 can be connected by a pulley and a belt drive. A second drive motor 512 for driving the second rotating rods 54 is mounted on the surface of the fixed brackets 510. A drive wheel 55 is fixedly mounted on the second rotating rod 54. The surface of the drive wheel 55 is provided with The structure has a rubber layer for better movement of the partition. A second drive motor 512 drives two second rotating rods 54 to rotate synchronously, which in turn drives the uppermost partition to the upper surface of the channel steel via drive wheels 55, separating the upper and lower layers of channel steel. A baffle 52 is fixedly installed on the base frame 51 to block the second layer of partition. A lifting mechanism is installed on the fixed frame 510 to drive the lifting bracket 53 to rise and fall. The lifting mechanism includes a first gear 56 coaxially fixedly connected to the second rotating rods 54, a second gear 57 meshing with the first gear 56, and two second transmissions. The second drive wheel 58 and the second drive chain 59 rotatably connected to the second drive wheel 58 are provided. A second clamp 511, fixedly connected to the second drive chain 59, is fixedly connected to the lifting bracket 53. One of the second drive wheels 58 is coaxially fixedly connected to the second gear 57, and the other second drive wheel 58 is rotatably connected to the base frame 51. In specific implementation: the second drive motor 512 starts, driving the two second rotating rods 54 to rotate synchronously. The drive wheel 55 (surface rubber layer) frictionally pushes the uppermost diaphragm towards the channel steel until the diaphragm completely covers the upper surface of the channel steel; baffle 52... The movement of the second layer of spacers is restricted to ensure that only a single layer of spacers is transported at a time. When the second rotating rod 54 rotates, the coaxial first gear 56 drives the meshing second gear 57 to rotate, which in turn drives the second transmission wheel 58 to rotate. The second transmission chain 59 moves under the traction of the second transmission wheel 58, and pulls the lifting bracket 53 vertically up and down along the guide rail 101 through the second clamp 511, so as to realize the automatic adjustment of the spacer layer height and facilitate the transport of the next spacer. After the spacer is placed, the drive wheel 55 rotates in the opposite direction to reset, and the lifting bracket 53 descends to the initial position to prepare for the transport of the next group.
