Description

Technical Field

[0001] The present invention relates to the technical field of flexible conveyor lines, in particular to a flexible conveyor line and a method for producing PET bottles. Background Art

[0002] Flexible conveyor lines are key equipment in modern industrial production. With their highly flexible characteristics, they can quickly adjust the conveying path, speed and direction according to production needs, and adapt to small-batch, multi-variety production models. Types such as magnetic-driven flexible conveyor lines and planar magnetic levitation conveyor systems use advanced electromagnetic principles to achieve precise drive.

[0018] The PET bottles transported in the present invention are relatively short and thick in shape.

[0019] A method for producing a flexible conveyor line for PET bottles, comprising the following steps:

[0020] S1: First, the built-in conveying unit will store some PET bottles, and the robotic arm unit will convey the PET bottles to the first conveyor line;

[0021] S2: The first conveyor line drives the PET bottles to move, and after passing through the guide mechanism, they are transferred to the second conveyor line;

[0022] S3: The second conveyor line will drive the PET bottles to continue moving and eventually fall into the collection unit;

[0023] S4: The collection unit will control the front and back of the PET bottles to facilitate subsequent assembly.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention provides a robotic arm unit. Since the flexible conveyor belt 1 on the first conveyor line is always in operation, if a PET bottle is directly placed in, the PET bottle will instantly come into contact with the moving flexible conveyor belt 1. Since the PET bottle has no initial speed, the PET bottle may continuously flip, causing the PET bottle at the front and the PET bottle at the back to overlap, increasing the probability of subsequent blockage and also causing the PET bottles to be in different front positions. Therefore, when the built-in electric cylinder drives the extrusion plate to retract, the servo motor 1 drives the reciprocating screw to rotate, thereby driving the moving block and the overall placement mechanism to move, so that the PET bottle has the same speed as the flexible conveyor belt 1.

[0026] 2. The present invention provides an air pump device. After the PET bottles enter the flexible conveyor belt 1 on the curved plate, due to the transmission distance limitation, the PET bottles need to enter the second conveyor line for further transmission. An air pump device is provided at the connection between the first conveyor line and the second conveyor line to continuously supply gas upward, so that the friction force of the PET bottles at the connection is reduced, and the PET bottles can smoothly enter the flexible conveyor belt 2.

[0027] 3. The present invention sets a guide mechanism, and the servo motor 3 drives the rotating shaft to rotate, thereby driving the guide plate to rotate toward the second conveyor line. At this time, the triangular plate is at the bottom, and the accumulated PET bottles will be driven into the second conveyor line. After that, when the servo motor 3 drives the guide plate to reset, the power supply will energize the electromagnetic block, so that the electromagnetic block generates an attraction to the magnetic plate, thereby causing the triangular plate to move upward along the guide rod, so that the triangular plate will not hinder the movement of subsequent PET bottles during the reset process.

[0028] 4. The present invention provides a collection unit. Especially for the present invention's transmission of relatively short and thick PET bottles, after the PET bottles slide onto the ramp, they will slide downward along the ramp. To ensure that the PET bottles are always facing up, a rough layer is provided at the bottom of the flip plate. When the PET bottles face down, the friction between the front of the PET bottles and the rough layer is large, which will hinder the PET bottles from continuing to move downward. The visual sensor also monitors the front and back of the PET bottles. When a PET bottle stays on the rough layer, the servo motor 4 will drive the flip plate to rotate, thereby tossing the PET bottle and turning it over, and then falling back onto the ramp to continue falling.

DETAILED DESCRIPTION

[0044] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0045] Example 1: Use Figures 1-14 A flexible conveyor line and method for producing PET bottles according to one embodiment of the present invention are described below.

[0046] like Figure 1-Figure 2 As shown, the flexible conveyor line for PET bottle production of the present invention includes a box shell 1 with a support base 2 at the bottom, a rear inlet 8 at the back of the box shell 1, and a built-in conveying unit on the inner wall of the box shell 1, and further includes:

[0047] A first conveyor line 5 and a second conveyor line 6 for flexible transportation. The conveying route of the first conveyor line 5 is provided with an arc, a robotic arm unit 4 for transferring the PET bottles in the built-in conveying unit 3 to the first conveyor line 5, and a collecting unit 7 for facilitating manual picking and sorting.

[0048] The first conveyor line 5 and the second conveyor line 6 are connected end to end and will transport the PET bottles to the collection unit 7;

[0049] When the present invention is working, the robotic arm unit 4 will drive the PET bottles on the built-in conveying unit to move and place them on the first conveyor line 5. After being transmitted by the first conveyor line 5, the PET bottles will enter the second conveyor line 6 and finally be transmitted to the collection unit 7 for subsequent operators to assemble the PET bottles.

[0050] like Figure 3-Figure 4 As shown, the robotic arm unit 4 includes a support plate 41, the outer surface of the support plate 41 is fixedly connected to a placing table 42, the top of the placing table 42 is fixedly connected to a multi-axis robotic arm 43 with multiple degrees of freedom, the top of the multi-axis robotic arm 43 is fixedly connected to a fixed block 44, and support frames 45 are symmetrically arranged on both sides of the fixed block 44. The support frames 45, one side of the support frame 45 is provided with a servo motor 46, the output end of the servo motor 46 is fixedly connected to a reciprocating screw 47, the outer surface of the reciprocating screw 47 is threadedly connected to a moving block 48, and the outer surface of the moving block 48 is provided with a placement mechanism 49 for temporarily storing PET bottles.

[0051] After the PET bottle enters the placement mechanism 49, the multi-axis robotic arm 43 will drive the entire placement mechanism 49 to move to the top of the first conveyor line 5. Since the flexible conveyor belt 57 on the first conveyor line 5 is always in operation, if the PET bottle is directly placed, the PET bottle will instantly come into contact with the moving flexible conveyor belt 57. Since the PET bottle has no initial speed, the PET bottle may continue to flip, causing the PET bottle at the front end to be stacked with the PET bottle at the rear end, increasing the probability of subsequent blockage and causing the PET bottles to not be on the same front. Therefore, in the process of the built-in electric cylinder 498 driving the extrusion plate 499 to retract, the servo motor 46 drives the reciprocating screw 47 to rotate, thereby driving the moving block 48 and the overall placement mechanism 49 to move, so that the PET bottle has the same speed as the flexible conveyor belt 57.

[0052] like Figure 5-Figure 6As shown, the placement mechanism 49 includes side plates 491 arranged on both sides of the moving block 48, and telescopic rods 492 are evenly arranged on the side plates 491. The output end of the telescopic rod 492 is provided with a flexible plate 493, and the side of the flexible plate 493 away from the telescopic rod 492 is fixedly connected to a placement bin 494. A support column 495 is also provided on the flexible plate 493. The outer surface of the placement bin 494 is fixedly connected to a support rod 496, and one end of the support rod 496 is fixedly connected to a ring 497. The inner wall of the placement bin 494 is evenly provided with built-in electric cylinders 498, and the output end of the built-in electric cylinder 498 is fixedly connected to an extrusion plate 499.

[0053] When the PET bottle enters the placement mechanism 49 from the built-in conveying unit 3, the telescopic rod 492 will extend to different lengths, so that the flexible plate 493 is in the same shape as the arc of the rotating disk 35, making it easier for the PET bottle to enter the placement bin 494 and be clamped by the squeezing plate 499.

[0054] The support plate 41 is arranged on the outer surface of the support seat 2, and the inner wall of the ring 497 is rotatably connected to the outer surface of the support column 495.

[0055] like Figure 7-Figure 8 As shown, the built-in transmission unit includes a hydraulic device 31 arranged on the top of the box shell 1, a telescopic rod 2 32 is provided at the bottom of the hydraulic device 31, the output end of the telescopic rod 2 32 is fixedly connected to a support block 1 33, the inner wall of the support block 1 33 is fixedly connected to a servo motor 2 34, the output end of the servo motor 2 34 is fixedly connected to a rotating disk 35, the outer surface of the rotating disk 35 is evenly provided with through-holes 36, the bottom of the rotating disk 35 is provided with a placement bin 2 37 aligned with the through-holes 36, the outer surface of the support block 1 33 is fixedly connected to a connecting plate 38, one end of the connecting plate 38 is fixedly connected to a support plate 2 39, the top of the support plate 2 39 is fixedly connected to a hydraulic press 310, the output port of the hydraulic press 310 is provided with a lower pressure plate 311, and the bottom of the lower pressure plate 311 is provided with a poking column 312 that can pass through the through-hole 36;

[0056] When the built-in conveying unit is working, the hydraulic device 31 will first control the telescopic rod 2 32 to drive the overall support block 1 33 to move downward, so that the placement bin 2 37 is aligned with the placement bin 1 494. Then the servo motor will drive the rotating disk 35 to rotate, and the placement bin 2 37 with the PET bottles will move to the placement mechanism 49. Then the hydraulic machine 310 will control the lower pressure plate 311 to move downward, and drive the poking column 312 to move the PET bottles in the placement bin 2 37 into the placement bin 1 494.

[0057] The poking pin 312 can push out the PET bottle placed in the placement bin 2 37 , causing it to fall into the placement bin 1 494 .

[0058] The specific workflow is as follows:

[0059] During operation, the hydraulic device 31 will first control the telescopic rod 2 32 to drive the overall support block 1 33 to move downward, so that the placement bin 2 37 is aligned with the placement bin 1 494, and then the servo motor will drive the rotating disk 35 to rotate, and the placement bin 2 37 with the PET bottle appropriately moves to the placement mechanism 49, and then the hydraulic device 310 will control the lower pressure plate 311 to move downward, and drive the poking column 312 to move the PET bottle in the placement bin 2 37 into the placement bin 1 494, and then the multi-axis robotic arm 43 will drive the placement mechanism 49 to move to the top of the flexible conveyor belt 1 57, and then the servo motor 1 46 will drive the reciprocating screw 47 to rotate, thereby driving the moving block 48 and the overall placement mechanism 49 to move, so that the PET bottle has the same speed as the flexible conveyor belt 1 57, and finally the built-in electric cylinder 498 drives the extrusion plate 499 to retract, so that the PET bottle falls onto the flexible conveyor belt 1 57.

[0060] Example 2: Use Figures 1-14 A flexible conveyor line and method for producing PET bottles according to one embodiment of the present invention are described below.

[0061] like Figure 9 As shown, a flexible conveyor line for PET bottle production of the present invention is based on the first embodiment. The first conveyor line 5 includes a curved plate 51 with supporting feet 52 evenly arranged on the bottom, the outer surface of the curved plate 51 is provided with a supporting block 53, the top of the supporting block 53 is fixedly connected with a partition 54 for placing dropped PET bottles, one end of the curved plate 51 is fixedly connected with a controller 55 of a driving device 56, the output end of the driving device 56 is provided with a flexible conveyor belt 57, and the end of the curved plate 51 close to the second conveyor line 6 is provided with an air pump device 58 to avoid accumulation and blockage of PET bottles at the connection between the first conveyor line 5 and the second conveyor line 6. The top of the air pump device 58 is fixedly connected with a guide mechanism 59.

[0062] The driving device 56 drives the flexible conveyor belt 57 to operate, thereby driving the PET bottles on the top of the flexible conveyor belt 57 to be transported. After the PET bottles enter the flexible conveyor belt 57 on the curved plate 51, due to the distance limitation of the transmission, the PET bottles need to enter the second conveyor line 6 to continue to be transported. An air pump device 58 is set at the connection between the first conveyor line 5 and the second conveyor line 6 to continuously supply gas upward, so that the friction force of the PET bottles at the connection is reduced, and they can smoothly enter the flexible conveyor belt 2 67.

[0063] like Figure 10As shown, the guide mechanism 59 includes an inclined plate 591 disposed on the top of the air pump device 58. The top of the inclined plate 591 is fixedly connected to a third support plate 592. The top of the third support plate 592 is fixedly connected to a third servo motor 593. The output end of the third servo motor 593 is fixedly connected to a rotating shaft 594. The bottom of the rotating shaft 594 is fixedly connected to a guide plate 595. The inner wall of the guide plate 595 is symmetrically provided with guide rods 596. The outer surface of the guide rod 596 is slidably connected to a triangular plate 597. The top of the triangular plate 597 is fixedly connected to a magnetic plate 598. The top of the guide plate 595 is fixedly connected to an electromagnetic block 599 connected to a power supply 5910.

[0064] When the electromagnetic block 599 is energized, it will attract the magnetic plate 598.

[0065] Although an air pump device 58 is provided to reduce the accumulation of PET bottles at the connection between the first conveyor line 5 and the second conveyor line 6, the air pump device 58 may fail as the device works for a long time, and the air outlet of the air pump device 58 may also be blocked by dust and impurities, causing PET bottles to accumulate here. At this time, the rotating shaft 594 is driven to rotate by the servo motor three 593, thereby driving the guide plate 595 to rotate toward the second conveyor line 6. At this time, the triangular plate 597 is at the bottom, and the accumulated PET bottles will be driven into the second conveyor line 6. After that, when the servo motor three 593 drives the guide plate 595 to reset, the power supply 5910 will energize the electromagnetic block 599, so that the electromagnetic block 599 generates an attraction to the magnetic plate 598, so that the triangular plate 597 moves upward along the guide rod 596, so that the triangular plate 597 will not hinder the movement of subsequent PET bottles during the reset process.

[0066] like Figure 11 As shown, the second conveyor line 6 includes a straight plate 61 with a second supporting foot 62 at the bottom, a third supporting block 63 is provided on the outer surface of the straight plate 61, a partition 64 is fixedly connected to the top of the third supporting block 63, and a controller 65 with a second driving device 66 is also provided on the outer surface of the straight plate 61, and a flexible transmission belt 67 is provided at the output end of the second driving device 66.

[0067] The working process of the second conveyor line 6 is the same as that of the first conveyor line 5 .

[0068] One end of the straight plate 61 close to the controller 2 65 is fixedly connected to one end of the arc plate 51 close to the air pump device 58 .

[0069] like Figure 12-13As shown, the collecting unit 7 includes an operating platform 71, a storage slot 72 is provided on the operating platform 71, a ramp 73 is fixedly connected to the top of the operating platform 71, a servo motor 4 74 is fixedly connected to the middle section of the ramp 73, a flip plate 75 is fixedly connected to the output end of the servo motor 4 74, a rough layer 76 is provided at the bottom of the flip plate 75, a support rod 2 77 is fixedly connected to the top of the ramp 73, a visual sensor 78 is fixedly connected to one end of the support rod 2 77, and a camera 79 is evenly provided at the bottom of the visual sensor 78.

[0070] After the PET bottle slides onto the inclined platform 73, it will slide downward along the inclined platform 73. In order to ensure that the PET bottles are always facing up, a rough layer 76 is set at the bottom of the flip plate. When the front of the PET bottle is facing down, the friction between the front of the PET bottle and the rough layer 76 is relatively large, which will hinder the PET bottle from continuing to move downward. The visual sensor 78 will also monitor the front and back conditions of the PET bottle. When a PET bottle stays on the rough layer 76, the servo motor 74 will drive the flip plate 75 to rotate, thereby tossing the PET bottle and turning it over, and then falling back onto the inclined platform 73 to continue falling.

[0071] like Figure 14 As shown, a method for producing a flexible conveyor line for PET bottles includes the following steps:

[0072] S1: First, the built-in conveying unit 3 stores some PET bottles, and the robotic arm unit 4 conveys the PET bottles to the first conveying line 5;

[0073] S2: The first conveyor line 5 drives the PET bottles to move, and after passing through the guide mechanism 59, they are transferred to the second conveyor line 6;

[0074] S3: The second conveyor line 6 drives the PET bottles to continue moving and eventually fall into the collection unit 7;

[0075] S4: The collecting unit 7 controls the front and back of the PET bottle to facilitate subsequent assembly.

[0076] The specific workflow is as follows:

[0077] During operation, the driving device 56 will drive the flexible conveyor belt 57 to operate, so that the PET bottles on the top of the flexible conveyor belt 57 are driven and transported, and then enter the second conveyor line 6 through the guiding mechanism 59 and finally fall onto the inclined platform 73, and then slide downward along the inclined platform 73. In order to ensure that the PET bottles are all in a front-facing state, a rough layer 76 is provided at the bottom of the flip plate. When the front of the PET bottle is facing down, the friction between the front of the PET bottle and the rough layer 76 is large, which will hinder the PET bottle from continuing to move downward. The visual sensor 78 will also monitor the front and back conditions of the PET bottle. When a PET bottle stays on the rough layer 76, the servo motor 4 74 will drive the flip plate 75 to rotate, thereby tossing the PET bottle and turning it over, and then falling onto the inclined platform 73 again to continue falling.

[0078] The PET bottles transported in the present invention are relatively short and thick in shape.

[0079] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
