Description

Technical Field

[0001] The invention relates to the technical field of manipulators, and in particular to an automated production line for pultruded plates. Background Art

[0002] After being formed, the FRP pultruded sheet is in strip shape, and the subsequent unloading needs to go through a series of actions such as winding, bundling, coding, sorting, and palletizing. Among them, the inner diameter of FRP is 1650mm~1670mm, the outer diameter is 2270mm~2280mm, and the width is 75mm~150mm, resulting in a variety of sizes of rolls. In the face of mixed loading of multiple specifications, the rolls need to be stacked in a specific order during palletizing.

[0003] In this regard, the material strips coming out of different forming stations are required to be sorted after being rolled up and before arriving at the palletizing station, resulting in waiting time for the material rolls at different stations, affecting the flow efficiency between the stations and the overall production efficiency. If the waiting time is to be reduced, each material roll needs to be equipped with a separate transfer mechanism, which increases the complexity and cost of the production line and even limits the design layout of the production line.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] See also Figures 1 to 8 As shown, this preferred embodiment provides an automated production line for pultruded plates, including a coiler 1, a conveyor line 2, a winding and bundling machine 3, a coding and labeling machine, and a coil unloading truss manipulator 4, wherein:

[0047] Several winding machines 1 are arranged side by side and used to wind the formed material strip into a material roll 6;

[0048] The conveyor line 2 is arranged on one side of each winder 1. The conveyor line 2 is divided into a loading section 21, a transition section 22, a first lifting section 23, a storage and matching section 24, a second lifting section 25 and a unloading section 26 along its own conveying direction, and each section is provided with an independent conveying roller unit. The roller unit of the storage and matching section 24 is provided with multiple layers. The roller units of the first lifting section 23 and the second lifting section 25 can be lifted to dock with any layer of the roller unit of the storage and matching section 24, so as to adjust the order of the multiple material rolls 6 output by the unloading section 26;

[0049] The winding and bundling machine 3 is arranged at the loading section 21 and is used to perform multiple winding and bundling of the material roll 6;

[0050] The coding and labeling machine is arranged in the transition section 22, and is used to print labels containing information of the material roll 6, and attach the labels to the corresponding material roll 6;

[0051] The unloading truss robot 4 is used to take out the material roll 6 in the winder 1 and move it to the upper material section 21, and grab the material rolls 6 of the lower material section 26 one by one to the palletizing station for palletizing.

[0052] As a result, the pultruded sheet automated production line realizes a series of actions such as transferring, wrapping and bundling, coding and labeling, and palletizing of the coil 6 after winding. In particular, the conveyor line 2 has the optional functions of conveying and storage, and can adjust the order of the coils 6 entering the loading section 21 and then output them to meet the requirements of orderly palletizing. There is no need to consider the loading order and speed of different coils 6, which optimizes the flow path of the coil 6, simplifies the production line layout, and improves the overall production efficiency.

[0053] Specifically, see Figures 1 to 5 The unloading truss robot 4 includes a frame 41, a walking assembly 42, a lifting assembly 43 and a clamping assembly 44, wherein:

[0054] The frame 41 covers the winder 1, the conveyor line 2 and the palletizing station.

[0055] The traveling assembly 42 is arranged on the frame 41, and the traveling assembly 42 comprises a moving trolley 421 suspended above the winding machine 1, the conveying line 2 and the palletizing station and capable of translating in the horizontal direction;

[0056] The lifting assembly 43 is disposed on the moving trolley 421, and the lifting assembly 43 includes a lifting seat 431 that can translate along the vertical direction;

[0057] The clamping assembly 44 is installed on the lifting seat 431 and is used to clamp the material roll 6.

[0058] Therefore, the material roll 6 is reliably grasped by the clamping component 44, the material roll 6 is transferred in the X-axis direction and the Y-axis direction by the walking component 42, and the material roll 6 is transferred in the Z-axis direction by the lifting component 43, which meets the needs of multi-position transfer and ensures flexible, accurate and stable movements.

[0059] Specifically, see Figure 6 The clamping assembly 44 includes a base plate 441, and a plurality of rotary cylinders 442 are evenly distributed in a ring shape on the front of the base plate 441. A baffle 443 is provided at the output end of the rotary cylinder 442. The baffle 443 is parallel to the base plate 441 and the spacing is greater than the width of the material roll 6. Each baffle 443 is driven by the corresponding rotary cylinder 442 to switch between a state of contracting toward the center and a state of opening outward.

[0060] When each rotary cylinder 442 is located in the inner circle of the material roll 6 and each baffle 443 is in an outwardly opened state, the material roll 6 is confined between the base plate 441 and the baffle 443;

[0061] When each baffle 443 is in a state of being retracted toward the center, the clamping assembly 44 can be convenient for loading an upright material roll 6 or releasing a flat material roll 6, thereby realizing the actions of vertically grabbing and horizontally releasing the material roll 6, and facilitating the adjustment of the posture of the material roll 6 during winding and bundling.

[0062] Optionally, the front side of the substrate 441 is further provided with a plurality of first electric cylinders 444 evenly distributed in a ring shape, the output direction of the first electric cylinders 444 is parallel to the substrate 441, and the output end of the first electric cylinder 444 is provided with a top plate 445, the top plate 445 is used to press the inner ring surface of the material roll 6, and the back side of the substrate 441 is provided with a plurality of second electric cylinders 446 evenly distributed in a ring shape, the output direction of the second electric cylinders 446 is parallel to the substrate 441, and the output end of the second electric cylinders 446 is provided with a pressure plate 447 opposite to the top plate 445, the pressure plate 447 is used to press the outer ring surface of the material roll 6, the top plate 445 and the pressure plate 447 cooperate to clamp the material roll 6, so as to effectively prevent the material roll 6 from spreading out during the transfer process.

[0063] Furthermore, the baffle 443 , the top plate 445 and the pressure plate 447 are all made of polyurethane or are coated with a polyurethane layer to avoid damaging the surface of the material roll 6 during contact and pressure application with the material roll 6 .

[0064] Preferably, there are four rotary cylinders 442, four first electric cylinders 444, and four second electric cylinders 446, and the base plate 441 is cross-shaped. A gap may be left between the cross-shaped base plate 441 and the material roll 6, so that the material roll 6 can be wrapped and bundled in the gap without loosening the clamping assembly 44.

[0065] In particular, the material roll 6 in the winder 1 is in an axially horizontal state, and the material roll 6 on the conveyor line 2 is in an axially vertical state. The unloading truss robot 4 also includes a flipping mechanism 45, which is arranged on the lifting seat 431 and is used to drive the clamping assembly 44 to switch between a horizontal posture and a vertical posture.

[0066] Specifically, the flipping mechanism 45 includes a connecting rod 451 and a third electric cylinder 452. The two connecting rods 451 are correspondingly installed on both sides of the lifting seat 431 and are hinged to the clamping assembly 44. The two ends of the third electric cylinder 452 are respectively connected to the lifting seat 431 and the clamping assembly 44. The third electric cylinder 452 is used to drive the clamping assembly 44 to rotate relative to the lifting seat 431 under the action of the connecting rod 451, thereby realizing a 90° flip of the clamping assembly 44 with the material roll 6.

[0067] Specifically, the lifting assembly 43 also includes a sleeve 432, which is installed on the moving trolley 421 along the Z-axis direction. The lifting seat 431 is inserted into the sleeve 432. A reduction motor 433 is arranged at the top of the sleeve 432. A Z-direction screw rod 434 is arranged on the output shaft of the reduction motor 433. A nut 435 that cooperates with the Z-direction screw rod 434 is arranged on the sleeve 432.

[0068] Therefore, a reduction motor 433 is used to drive the Z-direction screw rod 434 to drive the nut 435 and the lifting seat 431 to move up and down, with high transmission accuracy and precise movement; the Z-direction screw rod 434 is made of 45# steel, and is subjected to tempering and quenching heat treatment to effectively ensure the wear resistance of the transmission; the nut 435 is made of 94 bronze, which has good tensile strength, load-bearing and wear resistance; the nut 435 and the Z-direction screw rod 434 transmission have a mechanical self-locking function, and when the material roll 6 is grabbed and operated in the air, accidents such as sudden falling will not occur; the structure of the sleeve 432 and the lifting seat 431 sleeve can stabilize the structure and reduce the height, and the sleeve 432 and the lifting seat 431 are made of wear-resistant ductile iron, which can have good relative sliding performance.

[0069] Optionally, a slewing bearing 46 is installed between the moving trolley 421 and the sleeve 432, so that the lifting assembly 43 can rotate relative to the moving trolley 421, thereby driving the material roll 6 to rotate. The slewing bearing 46 can control the relative rotation of the inner and outer rings through an absolute value servo reducer to achieve multi-angle grabbing and winding and bundling actions.

[0070] Specifically, the walking assembly 42 also includes an X-guide rail 422 arranged on the frame 41, and a walking frame 423 capable of translating along the X-axis direction is arranged on the X-guide rail 422, and a Y-guide rail 424 is arranged on the walking frame 423. The moving trolley 421 is arranged on the Y-guide rail 424 and can translate along the Y-axis direction, thereby realizing the displacement adjustment of the clamping assembly 44 in the X-axis direction and the Y-axis direction to adapt to the position of the material roll 6.

[0071] Optionally, see Figure 7 A first rack 425 and a first guide bar 426 parallel to the X-guide rail 422 are provided on the frame 41, a first drive motor 427 and a first guide wheel 428 are provided on the walking frame 423, a first gear 429 is provided on the output shaft of the first drive motor 427, the first gear 429 is meshed with the first rack 425, and the first guide wheel 428 is in rolling contact with the first guide bar 426.

[0072] Similarly, the walking frame 423 is provided with a second rack and a second guide bar parallel to the Y guide rail 424, the moving trolley 421 is provided with a second drive motor and a second guide wheel, the output shaft of the second drive motor is provided with a second gear, the second gear is meshed with the second rack, and the second guide wheel is in rolling contact with the second guide bar.

[0073] Among them, the contact form of the guide wheel and guide bar further improves the translation stability; the gear rack is made of 45# steel and is processed and manufactured through tempering and quenching heat treatment to effectively ensure transmission stability.

[0074] In addition, the pultruded board automated production line also includes a wood block placing mechanism 5, which is used to place wooden boards for isolation and protection between the stacked material rolls 6.

[0075] Specifically, see Figure 8 The wood block placing mechanism 5 includes an X-direction slide rail 51 arranged above the stacking station, a movable seat 52 which can translate along the X-axis direction is arranged on the X-direction slide rail 51, a Z-direction slide rail 53 is arranged on the movable seat 52, a support arm 54 which can translate along the Z-axis direction is arranged on the Z-direction slide rail 53, a Y-direction slide rail 55 is arranged on the support arm 54, a wooden board bin 56 which can translate along the Y-axis direction is arranged on the Y-direction slide rail 55, and a wooden board release port is arranged at the bottom of the wooden board bin 56.

[0076] It should be noted that, according to the winding rhythm, only one unloading truss robot 4 is set here. One unloading truss robot 4 is between the winder 1 and the conveyor line 2 to complete the transfer action. The number of unloading truss robots 4 can also be increased as needed. In addition, scrapped products can also be unloaded to the designated position through the unloading truss robot 4.

[0077] In addition, the winder 1, the wrapping and bundling machine 3 and the coding and labeling machine all adopt existing technologies and are not the focus of protection, so they will not be described in detail here.
