Description

Technical Field

[0001] The present invention belongs to the field of manipulators, and in particular relates to a palletizing robot and a palletizing method for wall cloth processing. Background Art

[0002] Palletizing is the process of placing items neatly and regularly into stacks. The emergence of palletizing robots has made the palletizing process more convenient and faster.

[0003] Chinese patent CN102729242B discloses a palletizing robot gripper, which includes a main frame structure mainly composed of a front side plate, a rear side plate, a left side plate, a right side plate and a top plate, and has gripping teeth arranged at the bottom ends of the front and rear side plates. When the front and rear side plates clamp and grasp items, the gripping teeth can be supported on the bottom ends of the items to improve the stability of the items when grasping and prevent the items from falling during the grasping and conveying process.

[0004] However, since the bottom surface of the side panel is provided with grabbing teeth, in order for the palletizing robot gripper to smoothly grab the items, a suspended portion needs to be left at the bottom of the items before grabbing, which limits the scope of use of the palletizing robot gripper and reduces the applicability of the equipment; on the other hand, when the above-mentioned palletizing robot gripper stacks the grabbed items, the side panel needs to be moved far enough away from the items to completely separate the grabbing teeth at the bottom of the side panel from the items, so that sufficient space needs to be left around the items during stacking, and it is impossible to stack the items densely, which reduces the space utilization rate during stacking. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a palletizing robot and a palletizing method for wall cloth processing to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0013] A plurality of reinforcing strips are fixedly mounted on the outer side surface of the splint.

A guide sleeve is slidably installed on the lower end of the limiting cylinder, and the auxiliary support claw is horizontally installed on one side of the lower end of the guide sleeve.

[0015] Furthermore, a lifting guide groove located on the inner ring of the guide sleeve is opened on the side wall of the lower end of the limit cylinder, and a rotating guide groove arranged along the circumferential direction of the limit cylinder is opened on one side of the bottom end of the lifting guide groove, and the inner ring of the guide sleeve is fixedly installed with a guide connecting block that can slide along the lifting guide groove and the rotating guide groove.

[0016] Furthermore, a rotating shaft is rotatably mounted on the inner ring of the limiting cylinder, an external thread is provided on the lower end of the rotating shaft, and a threaded sleeve is rotatably mounted on the lower end of the rotating shaft through the external thread, and the outer surface of the threaded sleeve is fixedly connected to the inner end of the guide connecting block.

[0017] Furthermore, the lifting and rotating assembly further comprises a motor and a transmission shaft, wherein the motor is fixedly mounted on the bottom surface of the lower slide seat, and a driving gear is fixedly mounted on the output shaft of the motor;

[0018] The transmission shaft is rotatably mounted on the bottom surface of the lower sliding seat and is located below the motor. A transmission gear and a transmission bevel gear are fixedly mounted on the transmission shaft. The transmission gear is meshed and transmission-connected with the driving gear. The top end of the rotating shaft extends to the bottom of the transmission shaft, and a driven bevel gear is fixedly mounted on the top end of the rotating shaft and meshed and transmission-connected with the transmission bevel gear.

[0019] Furthermore, the outer ring of the lower end of the guide sleeve is provided with an annular groove, the lower end of the annular groove is sleeved with a sliding sleeve, one end of the sliding sleeve is fixedly connected to the auxiliary support claw, the upper end of the annular groove is sleeved with a torsion spring, one end of the torsion spring is fixedly connected to the end wall of the annular groove, and the other end of the torsion spring is fixedly connected to the top surface of the sliding sleeve;

[0020] A fixed stopper is fixedly mounted on the outer surface of the guide sleeve, and a movable stopper abutting against the outer end of the fixed stopper is fixedly mounted on the top surface of the auxiliary support claw.

[0021] Furthermore, the top surface of the auxiliary support claw is provided with a plurality of equally spaced lifting slots, a lifting seat is slidably installed inside the lifting slot, a support spring is abutted against the bottom end of the lifting seat, and a ball is movably mounted on the top end of the lifting seat.

[0022] The present invention also discloses a stacking method for wall cloth processing, and the specific steps are as follows:

[0023] During palletizing, the robot arm first drives the clamping mechanism to move, so that the two clamping plates in the clamping mechanism are respectively located on both sides of the wall cloth packaging box, and the bottom surfaces of the clamping plates are flush with the bottom surfaces of the wall cloth packaging box. Then, the telescopic drive components at both ends of the top support plate drive the two clamping plates to move toward each other and close together, so that the two clamping plates are respectively clamped on both sides of the wall cloth packaging box. Then, the robot arm drives the clamping mechanism to move upward, so that the wall cloth packaging box is grabbed and transported upward through the two clamping plates.

[0024] When the wall cloth packaging box is picked up, the auxiliary support claw is driven to move downward along the splint through the lifting and rotating assembly, and the auxiliary support claw is moved to the bottom of the splint, and then the auxiliary support claw is driven to rotate by the lifting and rotating assembly to rotate one end of the auxiliary support claw to the bottom of the inner side of the splint. At this time, the auxiliary support claw is located on the bottom surface of the wall cloth packaging box to provide auxiliary support for the wall cloth packaging box;

[0025] When the wall cloth packaging box is grabbed and transported to the top of the stacking position, the auxiliary support claw is first driven to rotate and reset through the lifting and rotating assembly, so that the auxiliary support claw is rotated and folded under the clamping plate, and then the auxiliary support claw is driven to rise and reset through the lifting and rotating assembly, so that the auxiliary support claw is moved to the outside of the clamping plate. Finally, the wall cloth packaging box is stacked at the stacking position, and the two clamping plates are driven to move in opposite directions and open through the telescopic driving assemblies at both ends of the top support plate, so that the two clamping plates release their clamping of the wall cloth packaging box, completing the stacking process of the wall cloth packaging box.

[0026] The present invention has the following beneficial effects:

[0027] 1. In the present invention, auxiliary support claws are provided on the bottom surface of the splint. When the splint clamps and grabs the article, the auxiliary support claws can be supported on the bottom surface of the article to provide auxiliary support for the article, thereby improving the stability of the stacking robot when grabbing and conveying articles and preventing the articles from falling during the grabbing and conveying process.

[0028] 2. The auxiliary support claws of the present invention are initially folded and mounted on the outer side surface of the lower part of the splint through the lifting and rotating assembly, which will not hinder the splint from clamping the items, so that there is no need to leave a suspended position at the bottom of the items when the splint clamps the items, thereby making the item clamping process more convenient and improving the applicability of the stacking robot; and after the splint clamps the items, the lifting and rotating assembly can first drive the auxiliary support claws to move downward along the splint, so that the auxiliary support claws move to the bottom of the splint, and then drive the auxiliary support claws to rotate, so that one end of the auxiliary support claws rotates and moves to the bottom of the inner side surface of the splint, so that the items can be clamped by the lifting and rotating assembly. The driving of the rotating assembly enables the auxiliary supporting claws to move quickly to the bottom surface of the clamped items to provide auxiliary support for the items, making the item support process more convenient and quick. When the items are grabbed and transported to the stacking position, the auxiliary supporting claws can be driven by the lifting and rotating assembly to reset and fold on the outer side surface of the lower end of the splint, thereby reducing the space occupied by the auxiliary supporting claws. After that, the splint only needs to be moved slightly outward to release the clamping of the splint on the items, and the items can be put down to complete the stacking process, thereby reducing the space required to be reserved for the stacking position during stacking, which is conducive to densely stacking items and improving space utilization during stacking.

[0029] 3. In the present invention, the auxiliary support claw is rotatably mounted on the guide sleeve through a torsion spring. When the guide sleeve rotates and drives the auxiliary support claw to rotate and support the bottom surface of the object, if the object slides down due to unstable clamping of the splint, causing the auxiliary support claw to rotate and abut against the side of the object, the auxiliary support claw can rotate in the opposite direction relative to the guide sleeve during the subsequent rotation of the guide sleeve, so that the auxiliary support claw abuts against the side of the object only under the torsional force of the torsion spring, and will not hard abut against the object due to the rotation of the guide sleeve, thereby preventing the auxiliary support claw from colliding with the object when the clamping and positioning of the object is inaccurate, causing damage to the object or the auxiliary support claw.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0045] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0046] Example 1: Please refer to Figures 1-4 As shown, the present invention is a palletizing robot, comprising a robotic arm 1 and a gripper mechanism 2 installed at the action end of the robotic arm 1, the gripper mechanism 2 comprising a top support plate 21 transmission-connected to the action end of the robotic arm 1, telescopic drive assemblies being installed at both ends of the top surface of the top support plate 21, and clamping plates 27 transmission-connected to the telescopic drive assemblies being installed at both ends of the bottom surface of the top support plate 21, the two sets of telescopic drive assemblies being able to drive the clamping plates 27 at both ends of the bottom surface of the top support plate 21 to move toward each other to close or move in the opposite direction to open; auxiliary support mechanisms 3 for supporting and positioning the clamped objects are installed on the clamping plates 27 at both ends of the bottom surface of the top support plate 21; the auxiliary support mechanism 3 comprises a lifting and rotating assembly and an auxiliary support claw 32, the auxiliary support claw 32 being folded and installed on the outer side surface of the lower part of the clamping plate 27 by the lifting and rotating assembly, and the lifting and rotating assembly being able to drive the auxiliary support claw 32 downward along the clamping plate 27 to move the auxiliary support claw 32 to the bottom of the clamping plate 27, and then drive the auxiliary support claw 32 to rotate to make one end of the auxiliary support claw 32 rotate and move to the bottom of the inner side surface of the clamping plate 27;

[0047] Specifically, when the palletizing robot is working, the robot arm 1 first drives the gripper mechanism 2 to move, so that the two clamps 27 in the gripper mechanism 2 are respectively located on both sides of the article, and the bottom surface of the clamps 27 is flush with the bottom surface of the article, and then the telescopic drive components at both ends of the top support plate 21 drive the two clamps 27 to move toward each other and close, so that the two clamps 27 are respectively clamped on both sides of the article, and then the robot arm 1 drives the gripper mechanism 2 to move upward, so that the article is grabbed and transported upward by the two clamps 27; while the article is being grabbed, the auxiliary support claw 32 is driven downward along the clamp 27 by the lifting and rotating component, and the auxiliary support claw 32 is moved to the bottom of the clamp 27, and then the auxiliary support claw is driven by the lifting and rotating component. The auxiliary support claw 32 is rotated and moved to the lower side of the inner side of the clamping plate 27 by the lifting and rotating assembly, and one end of the auxiliary support claw 32 is rotated and moved to the lower side of the inner side of the clamping plate 27. At this time, the auxiliary support claw 32 is located on the bottom surface of the article to provide auxiliary support for the article. When the article is grabbed and transported to the top of the stacking position, the auxiliary support claw 32 is first driven to rotate and reset by the lifting and rotating assembly, so that the auxiliary support claw 32 is rotated and folded under the clamping plate 27. The auxiliary support claw 32 is then driven to rise and reset by the lifting and rotating assembly, so that the auxiliary support claw 32 moves to the outer side of the clamping plate 27. Finally, the article is stacked in the stacking position, and the two clamping plates 27 are driven to move in opposite directions and open by the telescopic driving assemblies at both ends of the top support plate 21, so that the two clamping plates 27 release the clamping of the article, completing the stacking process of the article.

[0048] In this embodiment, when the splint 27 clamps and grabs the article, the auxiliary support claw 32 can be supported on the bottom surface of the article to provide auxiliary support for the article, thereby improving the stability of the stacking robot when grabbing and conveying the article and preventing the article from falling during the grabbing and conveying process; and the auxiliary support claw 32 is initially folded and installed on the outer side surface of the lower part of the splint 27 by the lifting and rotating assembly, which will not hinder the splint 27 from clamping the article, so that when the splint 27 clamps the article, there is no need to leave a suspended position at the bottom of the article, thereby making the article clamping process more convenient and improving the applicability of the stacking robot; and when the article is grabbed and conveyed to the stacking position, the auxiliary support claw 32 can be driven by the lifting and rotating assembly to reset and fold on the outer side surface of the lower end of the splint 27, thereby reducing the space occupied by the auxiliary support claw 32, and then the splint 27 only needs to be slightly moved outward to release the clamping of the splint 27 on the article, and the article can be put down to complete the stacking process, thereby reducing the space required for the stacking position during stacking, which is conducive to dense stacking of articles and improving space utilization during stacking.

[0049] Example 2: Please refer to Figure 2 、 Figure 4As shown, the difference between this embodiment and the above embodiment is that the telescopic drive assembly includes a hydraulic telescopic shaft 22 and a limiting guide groove 23. The hydraulic telescopic shaft 22 is fixedly installed on the top surface of the top support plate 21. An upper slide 24 is fixedly installed on the telescopic end of the outer side of the hydraulic telescopic shaft 22, and the upper slide 24 is slidably and tightly installed on the top surface of the top support plate 21; the limiting guide groove 23 is opened at the end of the top support plate 21, and a sliding connection block 25 is installed inside the limiting guide groove 23. The top end of the sliding connection block 25 is fixedly connected to the bottom surface of the upper slide 24, and the bottom end of the sliding connection block 25 is fixedly installed with a connecting support bar 26, which is fixedly installed on the outer side surface of the splint 27;

[0050] When clamping and grabbing items, the two upper slides 24 at both ends of the top surface of the top support plate 21 are driven to move toward each other by the contraction of the hydraulic telescopic shaft 22. At the same time, the upper slide 24 drives the lower clamping plate 27 to move synchronously through the sliding connecting block 25 and the connecting support bar 26, so that the two clamping plates 27 at both ends of the bottom of the top support plate 21 move toward each other and clamp the items; when the items are released for stacking, the two upper slides 24 at both ends of the top surface of the top support plate 21 are driven to move away in the opposite direction by the extension of the hydraulic telescopic shaft 22. At the same time, the upper slide 24 drives the lower clamping plate 27 to move synchronously through the sliding connecting block 25 and the connecting support bar 26, so that the two clamping plates 27 at both ends of the bottom of the top support plate 21 move in the opposite direction and open, thereby releasing the clamping of the items.

[0051] Furthermore, a lower sliding seat 28 is slidably installed on the bottom surface of the top support plate 21, and the lower sliding seat 28 is fixedly installed on the bottom end of the connecting support bar 26, and the bottom surface of the lower sliding seat 28 is fixedly installed with the connecting support bar 26; a plurality of reinforcing strips 29 are fixedly installed on the outer side surface of the splint 27; through the cooperation between the lower sliding seat 28 and the upper sliding seat 24, the stability of the installation of the sliding connecting block 25 and the connecting support bar 26 can be improved, thereby improving the stability of the splint 27 during installation and clamping. By setting the reinforcing strips 29, the rigidity of the splint 27 can be improved, and the splint 27 can be prevented from being abutted and deformed during the process of clamping and grasping objects, thereby improving the stability of the splint when clamping and grasping objects.

[0052] Example 3: Please refer to Figure 2 、 Figure 3 、 Figure 5-Figure 11As shown, the difference between this embodiment and the above embodiment is that the lifting and rotating assembly includes a limiting cylinder 31, which is fixedly mounted on the outer side of the reinforcing bar 29, and a guide sleeve 33 is slidably mounted on the lower end of the limiting cylinder 31, and a horizontally arranged auxiliary support claw 32 is mounted on one side of the lower end of the guide sleeve 33; a lifting guide groove 319 located on the inner ring of the guide sleeve 33 is opened on the side wall of the lower end of the limiting cylinder 31, and a rotation guide groove 320 arranged along the circumferential direction of the limiting cylinder 31 is opened on one side of the bottom end of the lifting guide groove 319, and a guide connecting block 318 that can slide along the lifting guide groove 319 and the rotation guide groove 320 is fixedly mounted on the inner ring of the guide sleeve 33; a rotating shaft 317 is rotatably mounted on the inner ring of the limiting cylinder 31, and the lower end of the rotating shaft 317 is provided with an external thread 321, and the lower end of the rotating shaft 317 is rotatably mounted with a threaded sleeve 322 through the external thread 321, and the outer surface of the threaded sleeve 322 is fixedly connected to the inner end of the guide connecting block 318;

[0053] The lifting and rotating assembly also includes a motor 311 and a transmission shaft 313. The motor 311 is fixedly mounted on the bottom surface of the lower sliding seat 28. A driving gear 312 is fixedly mounted on the output shaft of the motor 311. The transmission shaft 313 is rotatably mounted on the bottom surface of the lower sliding seat 28 and is located below the motor 311. A transmission gear 314 and a transmission bevel gear 315 are fixedly mounted on the transmission shaft 313. The transmission gear 314 is meshed and connected to the driving gear 312. The top end of the rotating shaft 317 extends below the transmission shaft 313, and a driven bevel gear 316 is fixedly mounted on the top end of the rotating shaft 317 and is meshed and connected to the transmission bevel gear 315.

[0054] After the clamping plate 27 clamps and grabs the object, the motor 311 drives the driving gear 312 to rotate, and the driving gear 312 engages to drive the transmission gear 314 to rotate, thereby driving the transmission shaft 313 and the transmission bevel gear 315 to rotate, and the transmission bevel gear 315 then engages to drive the driven bevel gear 316 to rotate, thereby driving the rotating shaft 317 to rotate. When the rotating shaft 317 rotates, the outer thread 321 at the lower end drives the threaded sleeve 322 downward. At this time, the threaded sleeve 322 drives the guide connecting block 318 to move downward along the lifting guide groove 319. At the same time, the guide connecting block 318 drives the guide sleeve 33 and the auxiliary support When the claw 32 moves downward, and the guide connecting block 318 moves downward and abuts the bottom end of the lifting guide groove 319, the auxiliary support claw 32 moves to the bottom of the clamping plate 27. Then, as the rotating shaft 317 continues to rotate, the rotating shaft 317 is locked by the external thread 321 to drive the threaded sleeve 322 to rotate synchronously. At this time, the threaded sleeve 322 drives the guide connecting block 318 to make a circular motion along the rotating guide groove 320. At the same time, the guide connecting block 318 drives the guide sleeve 33 and the auxiliary support claw 32 to rotate, so that one end of the auxiliary support claw 32 rotates and moves to the bottom of the inner side of the clamping plate 27 to provide auxiliary support for the items clamped and grasped by the clamping plate 27.

[0055] When the items are grabbed and transported to the stacking position and are about to be released for stacking, the motor 311 first drives the driving gear 312 to rotate in the opposite direction, thereby driving the rotating shaft 317 to rotate in the opposite direction through the transmission gear 314, the transmission shaft 313, the transmission bevel gear 315 and the driven bevel gear 316. At this time, the rotating shaft 317 first drives the threaded sleeve 322, the guide connecting block 318, the guide sleeve 33 and the auxiliary support claw 32 to rotate in the opposite direction and reset synchronously through the external thread 321. When the guide connecting block 318 rotates and abuts against the bottom end of the lifting guide groove 319, the rotating shaft 317 is rotated in the opposite direction and resets synchronously. When the handle 317 is in the upright position, the guide sleeve 332 is in the upright position, and the guide sleeve 333 is in the upright position, so that the bottom end position of the auxiliary support claw 32 is higher than the bottom end position of the splint 27, so as to facilitate the subsequent opening of the splint 27 for stacking and re-clamping to grab objects.

[0056] Furthermore, an annular groove 34 is provided on the outer ring of the lower end of the guide sleeve 33. A sliding sleeve 35 is mounted on the lower end of the annular groove 34. One end of the sliding sleeve 35 is fixedly connected to the auxiliary support claw 32. A torsion spring 36 is mounted on the upper end of the annular groove 34. One end of the torsion spring 36 is fixedly connected to the end wall of the annular groove 34, and the other end of the torsion spring 36 is fixedly connected to the top surface of the sliding sleeve 35. A fixed stopper 37 is fixedly mounted on the outer surface of the guide sleeve 33, and a movable stopper 38 is fixedly mounted on the top surface of the auxiliary support claw 32, which abuts against the outer end of the fixed stopper 37.

[0057] The auxiliary support claw 32 is initially stably installed on the lower end of the guide sleeve 33 under the torsional elastic force of the torsion spring 36 and the limiting action of the fixed stop block 37 and the movable stop block 38, so that when the guide sleeve 33 rotates, it can drive the auxiliary support claw 32 to rotate normally; and when the object slides down due to the unstable clamping of the splint 27, causing the auxiliary support claw 32 to rotate and abut against the side of the object, the auxiliary support claw 32 can rotate in the opposite direction relative to the guide sleeve 33 during the subsequent rotation of the guide sleeve 33, so that the auxiliary support claw 32 only abuts against the side of the object under the torsional force of the torsion spring 36 and remains motionless, and will not hard abut against the object due to the rotation of the guide sleeve 33, thereby preventing the auxiliary support claw 32 from colliding with the object when the object clamping positioning is inaccurate, causing damage to the object or the auxiliary support claw 32.

[0058] Furthermore, the top surface of the auxiliary support claw 32 is provided with a plurality of lifting grooves 323 arranged at equal intervals, and a lifting seat 39 is slidably installed inside the lifting groove 323, and a support spring 324 is installed at the bottom end of the lifting seat 39. The top of the lifting seat 39 is movably mounted with a ball 310. By arranging the ball 310 to support the bottom surface of the object in rolling contact, the friction resistance of the auxiliary support claw 32 when rotating and supporting on the bottom surface of the object can be increased, making the auxiliary support claw 32 more labor-saving when rotating. By arranging the support spring 324 and the lifting seat 39 to perform lifting and lowering buffering on the ball 310, the lifting and lowering support margin of the ball 310 can be increased, the fault tolerance of the auxiliary support claw 32 during support is increased, and the stable support work of the auxiliary support claw 32 is ensured.

[0059] Example 4: Please refer to Figures 1-11 As shown, this embodiment discloses a palletizing method for wall cloth processing. Taking the palletizing of packaging boxes loaded with wall cloth during the wall cloth processing process as an example, the specific palletizing steps are as follows:

[0060] First, the robot arm 1 drives the clamping mechanism 2 to move, so that the two clamping plates 27 in the clamping mechanism 2 are respectively located on both sides of the wall cloth packaging box, and the bottom surfaces of the clamping plates 27 are flush with the bottom surface of the wall cloth packaging box. Then, the telescopic drive components at both ends of the top support plate 21 drive the two clamping plates 27 to move toward each other and close, so that the two clamping plates 27 are respectively clamped on both sides of the wall cloth packaging box. Then, the robot arm 1 drives the clamping mechanism 2 to move upward, so that the wall cloth packaging box is grabbed and transported upward through the two clamping plates 27.

[0061] When the wall cloth packaging box is picked up, the auxiliary support claw 32 is driven by the lifting and rotating assembly to move downward along the clamping plate 27, and the auxiliary support claw 32 is moved to the bottom of the clamping plate 27. Then, the auxiliary support claw 32 is driven by the lifting and rotating assembly to rotate, and one end of the auxiliary support claw 32 is rotated and moved to the bottom of the inner side of the clamping plate 27. At this time, the auxiliary support claw 32 is located on the bottom surface of the wall cloth packaging box to provide auxiliary support for the wall cloth packaging box;

[0062] When the wall cloth packaging box is grabbed and transported to the top of the stacking position, the auxiliary support claw 32 is first driven to rotate and reset by the lifting and rotating assembly, so that the auxiliary support claw 32 is rotated and folded under the clamping plate 27, and then the auxiliary support claw 32 is driven to rise and reset by the lifting and rotating assembly, so that the auxiliary support claw 32 moves to the outside of the clamping plate 27. Finally, the wall cloth packaging box is stacked at the stacking position, and the two clamping plates 27 are driven to move in the opposite direction and open by the telescopic driving assembly at both ends of the top support plate 21, so that the two clamping plates 27 release the clamping of the wall cloth packaging box, completing the stacking process of the wall cloth packaging box.
