Description

Technical Field

[0001] The present invention relates to the technical field of logistics machinery and equipment, in particular to an automatic palletizing device and a method for using the same. Background Art

[0002] In the field of industrial production, in order to facilitate the transportation and storage of goods, it is often necessary to first stack the goods neatly on pallets, and then circulate the whole stack of goods to improve the efficiency of cargo transportation and storage costs.

[0003] There are still some problems with the existing automatic palletizing equipment during actual use:

[0004] 1. During the palletizing process, when the robot grasps some smooth-surfaced products, the relatively low friction or increased clamping force can easily cause the product's appearance to deform. Furthermore, some special products require a bottom support, otherwise they are prone to slipping, highlighting the shortcomings of existing technologies.

[0005] 2. In this situation where palletizing is completely dependent on the robotic arm to adjust the direct stacking of products, the impact of environmental and other factors may cause the palletizing to shift or be misaligned, which can easily lead to a significant impact on the height and stability of the palletizing. Secondly, it may tip over during transportation, which is not conducive to safe production regulations. Summary of the Invention

[0010] As mentioned above, the stacking protection mechanism includes a stacking arm, an adjustment bar, an arcuate bar and a limit bar. The stacking arm is provided with two and both surfaces are provided with connecting grooves vertically. One end of the adjustment bar is bent and its bending part is movably connected to the inside of the connecting groove through a rotating shaft. The arcuate bar is movably connected to the end of the adjustment bar away from the connecting groove through a rotating shaft. The limit bar is movably connected to the other end of the limit bar through a limit hinge, and the end of the limit bar away from the arcuate bar passes through the bottom end of the stacking arm and is connected to the opposite side thereof.

[0011] As mentioned above, the top end of the stacking arm passes through the movable slot and extends to the top end of the mounting frame. The width of the connection between the stacking arm and the movable slot is adapted, and the widths of the upper and lower ends of the stacking arm are both greater than the connection slot.

[0012] As mentioned above, the stacking protection mechanism also includes a pull rope, a guide wheel, a conveying wheel and a bracket, the brackets are respectively fixedly connected to the two sides of the top of the movable groove, the guide wheels are respectively rotatably connected to the opposite sides of the brackets through torque springs, the conveying wheel is located obliquely below the guide wheel and is connected to the inside of the movable groove by rotation, one end of the pull rope is fixedly connected to the outer side of the top of the stacking arm, and the other end of the pull rope passes through the hub of the conveying wheel in sequence and is wrapped around the hub of the guide wheel.

[0013] As mentioned above, the stacking drive mechanism includes a servo motor, a drive disk, an arc-shaped pull rod and a pull rod. The output end of the servo motor is fixedly connected to the drive disk through a coupling. The arc-shaped pull rods are symmetrical about a circle and are movably connected to the outer side of the drive disk through a rotating shaft. The pull rods are movably connected to the end of the arc-shaped pull rod away from the drive disk through a rotating shaft.

[0014] As mentioned above, the servo motor is fixedly connected to the top surface of the mounting bracket, the arc strip is arranged in an arc shape and is adapted to the arc shape of the driving disk surface, and the end of the pull rod away from the arc strip is movably connected to the top of the stacking arm through a rotating shaft.

[0015] The above-mentioned controllable stacking anti-dumping mechanism includes a driving motor, a main gear, a driving gear, a driving bar, a displacement platform and a stacking frame. The main gear is fixedly connected to the output end of the driving motor. The driving gears are provided with two and are symmetrically arranged to engage with the two main gears. The driving bars are respectively fixedly connected to the axis of the driving gear through a connecting shaft. The displacement platforms are respectively fixedly connected to the end of the driving bar away from the driving gear. The stacking frames are symmetrically arranged and are respectively movably connected to the surface of the displacement platform through hinges.

[0016] As mentioned above, the stacking rack is composed of several rectangular racks spliced ​​together by limit hinges. The stacking rack is tilted to both sides due to the influence of the limit hinges. The connection points of the stacking racks are fixedly connected with straightening bars, and the straightening bars follow the stacking racks at a certain tilt angle. The bottom end of the displacement platform is provided with two slide grooves, and the slide grooves are arc-shaped and adapted to the guide rails. The displacement platform is slidably connected to the guide rails through the slide grooves.

[0017] The above-mentioned controllable stacking anti-dumping mechanism also includes a main bevel gear, a driving bevel gear, a driving rod and a pushing frame. The main bevel gear is fixedly connected to the top of the driving motor, and the main bevel gear is located directly above the main gear. The driving bevel gear is meshed with the main bevel gear, and the driving rod passes through the driving bevel gear and extends to one side of the guide rail. A thread is provided on the outer side of the driving rod near one end of the guide rail. One side of the pushing frame is movably connected to the driving rod through a thread, and the other side of the pushing frame is close to the stacking cart.

[0018] A method for using an automatic palletizing device comprises the following steps:

[0019] S1. Install both ends of the mounting bracket on the mobile lifting equipment at the top of the working environment for lifting and moving debugging. Then set the conveying end of the conveyor belt at the position where the product needs to be transported, and install the entire assembly line equipment on the opposite side.

[0020] S2. Before palletizing, start the drive motor to rotate the drive gear through the main gear. At the same time, the drive gear drives the translation table to slide to the opposite side through the drive bar until the drive bars are parallel to each other. As the drive bar moves, the main bevel gear drives the drive bevel gear to rotate. At this time, the push frame moves backward as a whole due to the threaded connection of the drive rod. After adjustment, push the stacking cart to the opposite side of the translation table.

[0021] S3. Start the conveyor belt to transport the product. The displacement lifting device controls the mounting frame to move to the top of the product and then controls it to descend so that the product is located on the opposite side of the stacking arm.

[0022] S4, the servo motor controls the drive disc to rotate. At this time, the arc-shaped pull bar moves closer to the surface of the drive disc and pulls the pull rod to move to the opposite side. At this time, the pull rod pulls the stacking arm to clamp the product.

[0023] S5. When clamping the product, the two sides of the product will push up against the adjustment bar, causing the bend to move outward. At the same time, the arc bar at the other end of the adjustment bar drives the limit bar to move to the inside of the stacking arm on the opposite side. When the bend of the adjustment bar is completely parallel to the stacking arm, the limit bar moves to the bottom of the product. When the adjustment bar moves, the pull rope is pulled downward. At this time, the hubs of the guide wheel and the conveyor wheel are pulled to slide, and the pull rope wrapped around the guide wheel is pulled to loosen.

[0024] S6. Control the clamped product to move to the top of the stacking cart until the bottom of the product contacts the stacking cart. Automatically control the servo motor to rotate counterclockwise. At this time, the arc-shaped pull bar slowly disengages from the drive disk. At the same time, its other end pushes the stacking arm to both sides to release the product. When the product is out of the clamping state, the adjustment bar 502 is subjected to the reaction force of the pull rope. At the same time, its bend slowly returns to its original position. Then the arc-shaped bar pulls the limit bar to return to its original position.

[0025] S7. When the product is out of contact with the palletizing cart, its bottom end presses down on the straightening bar, so that the connecting stacking frame is tilted. Secondly, the distance between the opposite sides of the straightening bars on this section is less than the width of the product. After the product is palletized, the driving motor drives the main gear, so that the translation table moves to both sides. At the same time, the driving rod drives the pushing frame to push the palletizing cart outward, pushing the palletized products away from the equipment.

[0026] Beneficial effects

[0027] Compared with the existing technology, this automatic palletizing equipment and its use method have the following beneficial effects:

[0028] 1. The present invention provides a palletizing protection mechanism. When clamping the product, its two sides will press the adjustment bar upward to both sides, so that the bending part of the adjustment bar moves outward. At the same time, the arc bar at the other end of the adjustment bar drives the limit bar to move relatively laterally toward the inside of the palletizing arm. When the bending part of the adjustment bar is completely parallel to the palletizing arm, the limit bar moves to the bottom end of the product. When the adjustment bar moves, the pull rope is pulled downward, so that it slides on the hub of the conveying wheel and the pull rope wrapped around the guide wheel is pulled to loosen. This is conducive to enhancing the vibration generated when the equipment moves and causing the product to slip from the clamped state. Secondly, it avoids excessive clamping force that may cause damage to the equipment packaging and support the bottom of the product, thereby enhancing the safety performance of the equipment.

[0029] 2. The present invention sets up a stacking drive mechanism, which uses a servo motor to control the rotation of the drive disk. At this time, the arc-shaped pull bar is close to the surface of the drive disk, and at the same time, the pull rod is pulled to the opposite side. At this time, the pull rod pulls the stacking arm to clamp the product. Conversely, the servo motor is used to rotate counterclockwise. At this time, the arc-shaped pull bar slowly breaks away from contact with the drive disk, and at the same time, its other end pushes the stacking arm to both sides to release the product, which is conducive to facilitating the clamping operation of the product. Secondly, it cooperates with the stacking protection mechanism to a certain extent.

[0030] After the palletizing of the products is completed, the driving motor drives the main gear to move the displacement table to both sides, and the driving rod drives the pushing frame to push the palletizing cart outwards, pushing the palletized products away from the equipment, which is beneficial to prevent the products from tipping over during the palletizing operation, and at the same time ensures that the palletizing is neat, which is convenient for collective stacking in the later stage.

[0031] Other advantages, objects and features of the present invention will be set forth in part in the description which follows and, in part, will be apparent to those skilled in the art upon examination of the following or may be learned from practice of the invention.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] As shown in Figures 1-8, the present invention provides a technical solution: an automatic palletizing device, comprising a conveyor belt 1 and a mounting frame 2, a palletizing drive mechanism 3 fixedly connected to the middle position of the surface of the mounting frame 2, a group of bilaterally symmetrical movable grooves 4 are opened on the surface of the mounting frame 2, and a palletizing protection mechanism 5 is movably connected inside the movable groove 4, two symmetrical guide rails 6 are arranged directly below the mounting frame 2, the guide rails 6 are close to each other and are semicircular, a controllable palletizing anti-dumping mechanism 7 is arranged on the opposite side of the rear end of the guide rails 6, a palletizing cart 8 is arranged opposite the front end of the guide rails 6, and the conveyor belt 1 is located on one side of one of the guide rails 6.

[0044] As shown in Figures 1, 2, 4, 5 and 6, the stacking protection mechanism 5 includes a stacking arm 501, an adjustment bar 502, an arcuate bar 503 and a limit bar 504. The stacking arm 501 is provided with two connecting grooves 9 vertically opened on the surface of both. One end of the adjustment bar 502 is bent and its bending part is movably connected to the inside of the connecting groove 9 through a rotating shaft. The arcuate bar 503 is movably connected to the end of the adjustment bar 502 away from the connecting groove 9 through a rotating shaft. The limit bar 504 is movably connected to the other end of the limit bar 504 through a limit hinge, and the end of the limit bar 504 away from the arcuate bar 503 passes through the bottom end of the stacking arm 501 and is connected to the opposite side thereof. The top end of the stacking arm 501 passes through the movable slot 4 and extends to the top end of the mounting frame 2. The stacking arm 501 and the movable slot 4 are connected. The width of the connection is adapted, and the width of the upper and lower ends of the stacking arm 501 is greater than the connecting groove 9. The stacking protection mechanism 5 further includes a pull rope 505, a guide wheel 506, a conveying wheel 507 and a bracket 508. The bracket 508 is fixedly connected to the two sides of the top of the movable groove 4, and the guide wheel 506 is rotatably connected to the opposite sides of the bracket 508 through a torque spring. The conveying wheel 507 is located obliquely below the guide wheel 506 and is rotatably connected to the inside of the movable groove 4. One end of the pull rope 505 is fixedly connected to the outer side of the top of the stacking arm 501, and the other end of the pull rope 505 passes through the hub of the conveying wheel 507 in sequence and is wrapped around the hub of the guide wheel 506.

[0045] When clamping the product, its two sides will press upward and toward both sides of the adjustment bar 502, causing its bending part to move outward. At the same time, the arc-shaped bar 503 at the other end of the adjustment bar 502 drives the limiting bar 504 to move to the inside of the stacking arm 501 on the opposite side. When the bending part of the adjustment bar 502 is completely parallel to the stacking arm 501, the limiting bar 504 moves to the bottom of the product. When the adjustment bar 502 moves, the pull rope 505 is pulled downward at the same time, causing it to slide on the hub of the conveying wheel 507 and at the same time loosening the pull rope 505 wrapped around the guide wheel 506. This is conducive to enhancing the vibration generated when the equipment moves, which may cause the product to slip from the clamped state. Secondly, it avoids excessive clamping force, which may cause damage to the equipment packaging and support the bottom of the product, thereby enhancing the safety performance of the equipment.

[0046] As shown in Figures 1, 2, 4 and 5, the stacking drive mechanism 3 includes a servo motor 301, a drive disk 302, an arcuate pull bar 303 and a pull rod 304. The output end of the servo motor 301 is fixedly connected to the drive disk 302 through a coupling. The arcuate pull bar 303 is point-symmetrical and is movably connected to the outer side of the drive disk 302 through a rotating shaft. The pull rods 304 are all movably connected to the end of the arcuate pull bar 303 away from the drive disk 302 through a rotating shaft. The servo motor 301 is fixedly connected to the top surface of the mounting frame 2. The arcuate bar 503 is arranged in an arc shape and is adapted to the arc shape of the surface of the drive disk 302. The end of the pull rod 304 away from the arcuate pull bar 303 is movably connected to the top of the stacking arm 501 through a rotating shaft.

[0047] The servo motor 301 controls the rotation of the driving disk 302. At this time, the arc-shaped pull bar 303 approaches the surface of the driving disk 302 and pulls the pull rod 304 to move to the opposite side. At this time, the pull rod 304 pulls the stacking arm 501 to clamp the product. Conversely, the servo motor 301 rotates counterclockwise. At this time, the arc-shaped pull bar 303 slowly breaks away from contact with the driving disk 302. At the same time, its other end pushes the stacking arm 501 to both sides to release the product, which is conducive to facilitating the clamping operation of the product and secondly cooperates with the stacking protection mechanism 5 to a certain extent.

[0048] As shown in Figure 1, Figure 2, Figure 3, Figure 7 and Figure 8As shown, the controllable stacking anti-dumping mechanism 7 includes a driving motor 701, a main gear 702, a driving gear 703, a driving bar 704, a displacement platform 705 and a stacking rack 706. The main gear 702 is fixedly connected to the output end of the driving motor 701. Two driving gears 703 are symmetrically arranged and meshed with the two main gears 702. The driving bars 704 are respectively fixedly connected to the axis of the driving gear 703 through a connecting shaft. The displacement platforms 705 are respectively fixedly connected to the end of the driving bar 704 away from the driving gear 703. The stacking rack 706 is symmetrically arranged and movably connected to the surface of the displacement platform 705 through a hinge. The stacking rack 706 is composed of several rectangular frames spliced ​​together by limit hinges. The stacking rack 706 tilts to both sides under the influence of the limit hinges. The connection points of the stacking rack 706 are all fixedly connected with the straightening bars 10, and the straightening bars 10 follow the stacking rack 706. The palletizing anti-dumping mechanism 7 is controlled by a main bevel gear 707, a driving bevel gear 708, a driving rod 709 and a pushing frame 7010. The main bevel gear 707 is fixedly connected to the top of the driving motor 701, and the main bevel gear 707 is located directly above the main gear 702. The driving bevel gear 708 is engaged with the main bevel gear 707. The driving rod 709 passes through the driving bevel gear 708 and extends to one side of the guide rail 6. The outer side of the driving rod 709 near the end of the guide rail 6 is provided with a thread. One side of the pushing frame 7010 is movably connected to the driving rod 709 through a thread, and the other side of the pushing frame 7010 is close to the palletizing cart 8.

[0049] The motor drives the driving gear 703 to rotate through the main gear 702. At the same time, the driving gear 703 drives the translation platform 705 to slide to the opposite side through the driving bar 704 until the driving bars 704 are parallel to each other. When the driving bar 704 moves, the main bevel gear 707 drives the driving bevel gear 708 to rotate. At this time, the pushing frame 7010 is moved backward as a whole due to the threaded connection of the driving rod 709. After the adjustment is completed, the stacking trolley 8 is pushed to the opposite side of the translation platform 705. Then, when the product is out of contact with the stacking trolley 8, its bottom end presses down the straightening bar 10, so that the connected stacking frame 706 is swung. Secondly, the distance between the opposite sides of the swaying bars on this section is less than the width of the product. After the product palletizing is completed, the driving motor 701 drives the main gear 702, so that the translation platform 705 is displaced to both sides. At the same time, the driving rod 709 drives the pushing frame 7010 Pushing the stacking trolley 8 outwards to push the stacked products away from the equipment is beneficial to prevent the products from tipping over during the stacking operation, while ensuring that the stacking is neat and convenient for collective stacking in the later stage.

[0050] Working principle: Install both ends of the mounting frame 2 on the mobile lifting equipment at the top of the working environment for lifting and moving debugging, then set the conveying end of the conveyor belt 1 at the position where the product needs to be transported, and install the entire assembly line equipment on the opposite side. Before palletizing, start the drive motor 701 to drive the drive gear 703 to rotate through the main gear 702. At the same time, the drive gear 703 drives the displacement table 705 to slide to the opposite side through the drive bar 704 until the drive bars 704 are parallel to each other. When the drive bar 704 moves, the main bevel gear 707 drives the drive bevel gear 708 to rotate. At this time, the push frame 7010 is moved backward as a whole due to the threaded connection of the drive rod 709. After the adjustment is completed, push the stacking cart 8 to the opposite side of the displacement table 705, start the conveyor belt 1 for product transportation, and the displacement lifting equipment controls the mounting frame 2 to move to the top position of the product, and then controls it to descend, so that the product is located on the opposite side of the stacking arm 501. The servo motor 301 controls the drive disk 302 to rotate. At this time, the arc pull bar 303 The pull rod 304 is pulled close to the surface of the driving disk 302 and moved to the opposite side at the same time. At this time, the pull rod 304 pulls the stacking arm 501 to clamp the product. When clamping the product, the two sides of the product will press the adjustment bar 502 upward to the sides, causing the bending part to move outward. At the same time, the arc-shaped bar 503 at the other end of the adjustment bar 502 drives the limiting bar 504 to move to the opposite side toward the inside of the stacking arm 501. When the bending part of the adjustment bar 502 is completely parallel to the stacking arm 501, the limiting bar 504 moves to the bottom of the product. When the adjustment bar 502 moves, the pull rope 505 is pulled downward, causing it to slide on the hub of the conveying wheel 507 and at the same time, the pull rope 505 wrapped around the guide wheel 506 is loosened, controlling the clamped product to move to the top of the stacking cart 8 until the bottom of the product contacts the stacking cart 8. The servo motor 301 is automatically controlled to rotate counterclockwise. At this time, the arc-shaped pull bar 303 slowly disengages from the contact with the drive disk 302. At the same time, its other end pushes the stacking arm 501 to both sides to release the product. When the product is out of the clamping state, the adjustment bar 502 is subjected to the reaction force of the pull rope 505. At the same time, its bend slowly returns to its original position. Then the arc-shaped bar 503 pulls the limit bar 504 to return to its original position. When the product is out of contact with the stacking cart 8, its bottom end presses down on the straightening bar 10, thereby causing the connecting stacking frame 706 to be swung in one section. Secondly, the distance between the opposite sides of the swaying bars on this section is less than the width of the product. After the product stacking is completed, the drive motor 701 drives the main gear 702, thereby causing the displacement table 705 to move to both sides. At the same time, the drive rod 709 drives the push frame 7010 to push the stacking cart 8 outward, pushing the stacked products away from the equipment.

5. The method for using the automatic palletizing equipment according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1. Install both ends of the mounting frame (2) on the mobile lifting device at the top of the working environment for lifting and moving debugging, then set the conveying end of the conveyor belt (1) at the position where the product needs to be transported, and at the same time install the entire assembly line equipment at the opposite side; S2. Before palletizing, the driving motor (701) is started to drive the driving gear (703) to rotate through the main gear (702). At the same time, the driving gear (703) drives the translation platform (705) to slide to the opposite side through the driving bar (704) until the driving bars (704) are parallel to each other. When the driving bar (704) moves, the main bevel gear (707) drives the driving bevel gear (708) to rotate. At this time, the pushing frame (7010) is moved backward as a whole due to the threaded connection of the driving rod (709). After the adjustment is completed, the palletizing cart (8) is pushed to the opposite side of the translation platform (705); S3, starting the conveyor belt (1) to convey the product, the displacement lifting device controls the mounting frame (2) to move to the top position of the product, and then controls it to descend, so that the product is located on the opposite side of the stacking arm (501); S4, the servo motor (301) controls the driving disk (302) to rotate, at which time the arc-shaped pull bar (303) approaches the surface of the driving disk (302) and simultaneously pulls the pull rod (304) to move to the opposite side, at which time the pull rod (304) pulls the stacking arm (501) to clamp the product; S5. When the product is clamped, the two sides of the product will press upward against the adjusting bar (502) to move the bending part outward. At the same time, the arc-shaped bar (503) at the other end of the adjusting bar (502) drives the limiting bar (504) to move relatively laterally to the inside of the stacking arm (501). When the bending part of the adjusting bar (502) is completely parallel to the stacking arm (501), the limiting bar (504) moves to the bottom of the product. When the adjusting bar (502) moves, the pull rope (505) is pulled downward. At this time, the pull rope slides on the hubs of the guide wheel (506) and the conveying wheel (507) and pulls the pull rope (505) wrapped around the guide wheel (506) to loosen. S6, control the clamped product to move to the top of the stacking cart (8) until the bottom of the product contacts the stacking cart (8), and automatically control the servo motor (301) to rotate counterclockwise. At this time, the arc-shaped pull bar (303) slowly breaks away from the contact with the drive disk (302), and at the same time, its other end pushes the stacking arm (501) to both sides to release the product. When the product is out of the clamping state, the adjustment bar (502) is subjected to the reaction force of the pull rope (505), and at the same time, its bend slowly returns to its original position, and then the arc-shaped bar (503) pulls the limit bar (504) to return to its original position; S7. When the product is out of contact with the stacking trolley (8), its bottom end presses down the straightening bar (10), thereby straightening a section of the connected stacking frame (706). Secondly, the distance between the opposite sides of the straightening bar on this section is less than the width of the product. After the product stacking is completed, the driving motor (701) drives the main gear (702), thereby causing the displacement table (705) to move to both sides. At the same time, the driving rod (709) drives the pushing frame (7010) to push the stacking trolley (8) outward, pushing the stacked products away from the equipment.
