Abstract
Description
Technical Field
[0001] This invention relates to the field of plastic bottle technology, and more specifically to an automatic plastic bottle picking device. Background Technology
[0002] When recycling plastic bottles, picking them up from the ground involves lifting them up and conveying them horizontally, and how to pick them up effectively is a major challenge. Most existing plastic bottle picking devices use robotic arms to grip each bottle individually. However, the overall movement speed of these arms is slow, and identifying the bottle's location and generating a path takes considerable time, making them unsuitable for large-scale picking. Therefore, there is a need to design an automated plastic bottle picking device capable of handling large quantities of plastic bottles at a faster speed. Summary of the Invention
[0003] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide an automatic plastic bottle picking device that can be applied to the picking of large quantities of plastic bottles and has a fast picking speed.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides an automatic plastic bottle picking device, including a mobile vehicle body, a swing arm, and a support guide frame installed at the front end of the mobile vehicle body. The support guide frame includes two connecting side plates and a guide sliding inclined plate connecting the two connecting side plates. The connecting side plates are fixedly connected to the mobile vehicle body. The bottom of the guide sliding inclined plate is provided with a rotatable support wheel. One end of the swing arm is rotatably connected to the connecting side plate, and a first rotating push rod that can rotate clockwise is provided on the rotation axis of the swing arm and the connecting side plate. The other end of the swing arm is provided with a second rotating push rod that can rotate clockwise. A third rotating push rod that can rotate is provided on the mobile vehicle body. The third rotating push rod is used to push the plastic bottle pushed out along the top of the guide sliding inclined plate downward. The mobile vehicle body is provided with a guide pushing mechanism for guiding the second rotating push rod inward. Each connecting side plate is provided with an arc-shaped groove coaxial with the rotation axis of the swing arm. A sliding column inserted into the arc-shaped groove is fixedly provided on the side of the swing arm.
[0005] Preferably, it also includes a pressing mechanism and a synchronous lifting mechanism. The pressing mechanism is fixedly installed on the top of the two connecting side plates, and the synchronous lifting mechanism is fixedly installed on the side of the connecting side plates. The pressing mechanism includes a pressing plate that can press down, and the synchronous lifting mechanism includes a hinge rod and a swing rod. The middle part of the swing rod is rotatably installed on the connecting side plate. One end of the hinge rod is hinged to the sliding column, and the other end of the hinge rod is hinged to the bottom of the swing rod. The top of the swing rod is drivenly connected to the pressing mechanism. When the swing arm is lifted by the plastic bottle, the sliding column pulls the swing rod to rotate counterclockwise, and the swing rod lifts the pressing plate on the pressing mechanism. When the swing arm is separated from the plastic bottle, the swing rod rotates clockwise, and the pressing plate presses down to the end of the plastic bottle.
[0006] Preferably, the pressing mechanism includes a pressing plate, a transmission frame, and two guide pillars. The guide pillars are vertically slidable on the guide slide via a guide slide block. The pressing plate is fixedly installed at the bottom of the two guide pillars, and the transmission frame is fixedly installed at the top of the two guide pillars. The top of the swing arm contacts the bottom of the transmission frame.
[0007] Preferably, it further includes a downward pushing mechanism, which is fixedly installed between the two connecting side plates. The downward pushing mechanism includes two single-sided pushing mechanisms, each of which includes a pushing plate, a triangular plate, an elastic telescopic rod, and a connecting shaft. The pushing plate is horizontally slidably installed between the two connecting side plates. The elastic telescopic rod is fixedly installed on the top of the pressing plate and provides an outward elastic force to the pushing plate. The connecting shaft is fixedly installed on the top of the pushing plate, and the end of the elastic telescopic rod is provided with a sleeve for the connecting shaft to be inserted. The triangular plate is fixedly installed on the bottom of the pressing plate, and the top of the pushing plate is provided with a ramp that contacts the triangular plate.
[0008] Preferably, the swing arm has a shaped structure, and the transmission frame is provided with a horizontal plate for contacting the swing arm.
[0009] Preferably, a slide block is fixedly provided at the bottom of each inner push plate, and a slide rail is fixedly provided between the two connecting side plates, with the slide block and the slide rail slidably connected.
[0010] Preferably, it further includes a rotary drive mechanism for simultaneously driving rotary pusher one, rotary pusher two, and rotary pusher three to rotate at the same speed. The rotary drive mechanism is fixedly installed on the mobile vehicle body. The rotary drive mechanism includes a pulley group one, a pulley group two, and a rotary driver. The rotary driver is drivenly connected to rotary pusher three. Pulley group two is drivenly connected to rotary pusher one and rotary pusher three. Pulley group one is drivenly connected to rotary pusher one and rotary pusher two.
[0011] Preferably, a guide pushing mechanism is also fixedly installed on the mobile vehicle body. The guide pushing mechanism includes two single-sided pushing mechanisms. Each single-sided pushing mechanism includes a rotary motor, a pushing wheel, a guide wheel one, a guide wheel two, a guide wheel three, and a base plate. The rotary motor drives the guide wheel one, the pushing wheel, the guide wheel two, and the guide wheel three in series through multiple pulley sets. The pushing wheels on the two single-sided pushing mechanisms are used to push the plastic bottle to move inward. The base plate is installed between the two single-sided pushing mechanisms.
[0012] Preferably, multiple star-shaped wheels are fixedly installed on rotating push rod one, rotating push rod two, and rotating push rod three, and the star-shaped wheels on rotating push rod one and rotating push rod two are staggered.
[0013] The beneficial effects of the present invention are as follows: the automatic plastic bottle picking device uses rotating pusher one, rotating pusher two and rotating pusher three to transport plastic bottles, which can quickly pick up plastic bottles from the ground and transport them to a horizontal position, and is suitable for picking up large quantities of plastic bottles.
[0014] During the conveying process, when the second rotating pusher is lifted upwards by the plastic bottle, the pressing plate will automatically rise upwards, allowing the plastic bottle to be positioned below the pressing plate. When the second rotating pusher separates from the plastic bottle, the pressing plate will automatically press the second rotating pusher downwards, ensuring that the plastic bottle can move to the area below the third rotating pusher, preventing the third rotating pusher from being unable to convey the plastic bottle.
[0015] In addition, the device can automatically adjust the height of the pressing plate according to the different lengths of plastic bottles, ensuring that the plastic bottles can be squeezed downwards. Attached Figure Description

Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example: This invention provides an automatic plastic bottle picking device, such as... Figure 1-10As shown, the device includes a mobile vehicle body 1, a swing arm 8, and a support guide 2 installed at the front end of the mobile vehicle body 1. The support guide 2 includes two connecting side plates 2c and a guide ramp 2b connecting the two connecting side plates 2c. The connecting side plates 2c are fixedly connected to the mobile vehicle body 1. The bottom of the guide ramp 2b is provided with a rotatable support wheel 2a. The distance between the support wheel 2a and the ground is less than half the thickness of a single plastic bottle. One end of the swing arm 8 is rotatably connected to the connecting side plate 2c, and a clockwise rotation axis is provided on the axis of rotation of the swing arm 8 and the connecting side plate 2c. A rotating pusher 9 is mounted on the first rotating rod, and a rotating pusher 10, capable of clockwise rotation, is mounted on the other end of the swing arm 8. A rotating pusher 3, capable of rotation, is mounted on the moving vehicle 1. The rotating pusher 3, 11, is used to push the plastic bottle 12, which is pushed downwards along the top of the guide ramp 2b. The moving vehicle 1 is equipped with a guide pushing mechanism 7 for guiding the rotating pusher 2, 10, inwards. Each connecting side plate 2c has an arc-shaped groove 2d coaxial with the rotation axis of the swing arm 8. A sliding column 8a, inserted into the arc-shaped groove 2d, is fixedly mounted on the side of the swing arm 8. As the moving vehicle 1 moves closer to the plastic bottle 12, the plastic bottle is pulled under the rotating pusher 2, 10, by the inward rotational thrust of the rotating pusher 2, 10, and the impact force between the rotating pusher 2, 10, and the plastic bottle 12. The support wheel 2a then blocks the plastic bottle 12, while the rotating pusher 2, 10, by its own restoring thrust, allows the plastic bottle 12 to slide upwards along the guide ramp 2b.
[0030] It should be noted that during the process of the plastic bottle 12 being rolled under the rotating pusher 2 10 and sliding upward along the guide slide 2b, the rotating pusher 2 10 will be lifted by the plastic bottle 12, and the rotating pusher 2 10 will drive the swing arm 8 to rotate, and the slide column 8a will rotate counterclockwise along the arc groove 2d.
[0031] As the plastic bottle 12 slides downwards, it comes into contact with the rotating push rod 9. The pushing force of the rotating push rod 9 then pushes the plastic bottle 12 to continue sliding upwards, eventually coming into contact with the rotating push rod 11. The rotating push rod 11 pushes the end of the plastic bottle 12 downwards and into the storage mechanism.
[0032] The pressing mechanism 3 includes a pressing plate 3a, a transmission frame 3b, and two guide pillars 3d. The guide pillars 3d are vertically slidably mounted on the guide slide 3c via a guide slide 3c. The pressing plate 3a is fixedly mounted on the bottom of the two guide pillars 3d, and the transmission frame 3b is fixedly mounted on the top of the two guide pillars 3d. The top of the swing rod 5b contacts the bottom of the transmission frame 3b. When the swing rod 5b is pushed to rotate, it pushes the transmission frame 3b upward, causing the transmission frame 3b to pull the pressing plate 3a upward via the guide pillars 3d. When the swing rod 5b rotates downward, the pressing plate 3a can instantly press down on the plastic bottle 12. Because the rotating pusher 10 rotates downward at a very fast speed, the pressing speed is also relatively fast.
[0033] Because the plastic bottle 12 always deviates slightly from the center during each upward conveying process, a downward pushing mechanism 4 is included to ensure that the plastic bottle 12 is conveyed to the center. The downward pushing mechanism 4 is fixedly installed between the two connecting side plates 2c and includes two single-sided pushing mechanisms. Each single-sided pushing mechanism includes a pushing plate 4a, a triangular plate 4b, an elastic telescopic rod 4c, and a connecting shaft 4d. The pushing plate 4a is horizontally slidable between the two connecting side plates 2c. The elastic telescopic rod 4c is fixedly installed on the top of the pressing plate 3a and provides an outward elastic force to the pushing plate 4a. The connecting shaft 4d is fixedly installed on the top of the pushing plate 4a, and the end of the elastic telescopic rod 4c is provided with a sleeve for the connecting shaft 4d to be inserted. The triangular plate 4b is fixedly installed on the bottom of the pressing plate 3a, and the top of the pushing plate 4a has a ramp 4e that contacts the triangular plate 4b. Figure 5 As shown, this state is the position after the pressure plate 3a is pressed down, and Figure 7 The image shows the state of the pressing plate 3a before it is pressed down. When the pressing plate 3a is pressed down, the triangular plate 4b generates an inward pushing force, which pushes the inner push plates 4a on the two single-sided inward pushing mechanisms inward. Furthermore, the inward pressing of the inner push plates 4a is synchronized with the downward pressing of the pressing plate 3a, allowing the plastic bottle 12 to be adjusted towards the center during the conveying process. When the pressing plate 3a moves upward, the elastic telescopic rod 4c pushes the inner push plates 4a outward, preparing for the next inward pushing operation of the inner push plates 4a.
[0034] The swing arm 5b has an L-shaped structure, and the transmission frame 3b is equipped with a horizontal plate 3e for contacting the swing arm 5b. Through the structural design of the swing arm 5b and the horizontal plate 3e, during the rotation of the swing arm 5b, it can be ensured that the swing arm 5b remains in contact with the horizontal plate 3e throughout the entire rotation, thereby pushing the horizontal plate 3e upward.
[0035] Each inner push plate 4a has a fixed slide block 4f at its bottom, and a slide rail 4h is fixed between the two connecting side plates 2c. The slide block 4f and the slide rail 4h are slidably connected. The slide block 4f and the slide rail 4h provide sliding guidance for the movement of the inner push plate 4a, ensuring that the two inner push plates 4a can slide horizontally.
[0036] It also includes a rotary drive mechanism 6 for simultaneously driving rotary pusher 9, rotary pusher 10, and rotary pusher 31 to rotate at the same speed. The rotary drive mechanism 6 is fixedly mounted on the mobile vehicle body 1. The rotary drive mechanism 6 includes a pulley assembly 6a, a pulley assembly 6b, and a rotary driver 6c. The rotary driver 6c is driven by rotary pusher 31. Pulley assembly 6b is driven by rotary pusher 9 and rotary pusher 31. Pulley assembly 6a is driven by rotary pusher 9 and rotary pusher 20. With the help of pulley assembly 6a, even when the swing arm 8 is in a swinging state, rotary pusher 210 can still be driven to rotate through the power transmission of pulley assembly 6a. In addition, when rotary pusher 31 rotates, it will drive rotary pusher 9 to rotate through pulley assembly 6b, so that rotary pusher 9, rotary pusher 21, and rotary pusher 31 can all rotate at the same speed.
[0037] The mobile vehicle body 1 is also fixedly equipped with a guide pushing mechanism 7, which includes two single-sided pushing mechanisms. Each single-sided pushing mechanism includes a rotary motor 7a, a pushing wheel 7b, a first guide wheel 7c, a second guide wheel 7d, a third guide wheel 7e, and a base plate 7f. The rotary motor 7a drives the first guide wheel 7c, the pushing wheel 7b, the second guide wheel 7d, and the third guide wheel 7e in series through multiple pulley sets. The pushing wheel 7b on the two single-sided pushing mechanisms is used to push the plastic bottle 12 inward. The base plate 7f is installed between the two single-sided pushing mechanisms. The plastic bottle 12 delivered to the base plate 7f is certainly not located at the center of the base plate 7f. By pushing the plastic bottle 12 inward by the pushing wheel 7b, the plastic bottle 12 can be inserted between the third guide wheel 7e and the second guide wheel 7d, that is, the plastic bottle 12 is limited and ensured that the plastic bottle 12 is in the center, which facilitates better control of the center position of the plastic bottle 12 in the future.
[0038] Multiple star-shaped wheels 9a are fixedly installed on rotating pusher 1 (9), rotating pusher 2 (10), and rotating pusher 3 (11), and the star-shaped wheels 9a on rotating pusher 1 (9) and rotating pusher 2 (10) are staggered. The star-shaped wheels 9a can compress and convey the plastic bottle 12, and different types can be replaced according to the different diameters of the plastic bottle 12.
[0039] In use, the rotating pusher 2 10 contacts the plastic bottle 12. During the contact movement, the rotating pusher 2 10 is lifted upward and eventually fed between the rotating pusher 1 9 and the guide slide 2b, and is pushed upward along the guide slide 2b.
[0040] Meanwhile, because the plastic bottles 12 have different lengths, the plastic bottles 12 will lift the rotating pusher 2 10 to different heights, that is, the pressing plate 3a will also rise to different heights. The higher the pressing plate 3a rises, the longer the plastic bottle 12 is.
[0041] When the plastic bottle 12 is removed from the rotating pusher 10, it will be positioned below the pressing plate 3a. The downward pressure of the pressing plate 3a then presses the end of the plastic bottle 12 under the rotating pusher 11. Simultaneously, the pressing plate 3a moves downward, pushing the two inner push plates 4a inward, thus centering the plastic bottle 12. The plastic bottle 12, conveyed by the rotating pusher 11, will then enter the guide pusher mechanism 7.
[0042] The automatic plastic bottle picking device uses rotating pusher 19, rotating pusher 210 and rotating pusher 311 to transport plastic bottles 12, which can quickly pick up plastic bottles 12 from the ground and transport them to a horizontal position. It is suitable for picking up large quantities of plastic bottles.
[0043] During the conveying process, when the rotating pusher 2 10 is lifted upward by the plastic bottle 12, the pressing plate 3a will automatically lift upward, allowing the plastic bottle 12 to be positioned below the pressing plate 3a. When the rotating pusher 2 10 separates from the plastic bottle 12, the pressing plate 3a will automatically press down on the rotating pusher 2 10, ensuring that the plastic bottle 12 can move to the area below the rotating pusher 3 11, thus preventing the rotating pusher 3 11 from failing to convey the plastic bottle 12.
[0044] In addition, the device can automatically adjust the height of the pressing plate 3a according to the different lengths of plastic bottles, ensuring that the plastic bottle 12 can be squeezed downwards.
[0045] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
