Description

Technical Field

[0001] The present invention relates to the technical field of logistics mechanical equipment, and 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 in actual use:

[0004] 1. During the palletizing process, when the robot grabs some products with smooth surfaces, the relative friction is small, or the clamping force is increased, which can easily cause the appearance of the product to deform. Secondly, some special products need to be supported, otherwise they are prone to slipping, which highlights the shortcomings of the existing technology;

[0005] 2. In this situation where palletizing is completely dependent on the robot to adjust the direct stacking of products, the environment and other factors may cause the palletizing to be offset or misaligned, which can easily affect the height and stability of the palletizing. Secondly, it may topple over during transportation, which is not conducive to safety production standards. Summary of the invention

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

[0014] As mentioned above, the servo motor is fixedly connected to the top surface of the mounting frame, the arc strip is arranged in an arc shape and matches 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 controllable anti-dumping mechanism for stacking mentioned above 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 gear is provided with two and is symmetrically arranged to mesh with the two main gears. The driving bar is fixedly connected to the axis of the driving gear through a connecting shaft, and the displacement platform is fixedly connected to one end of the driving bar away from the driving gear. The stacking frame is symmetrically arranged and is movably connected to the surface of the displacement platform through hinges.

[0016] As mentioned above, the stacking rack is composed of several rectangular racks connected by limit hinges, and the stacking rack is tilted to both sides due to the influence of the limit hinges. The connection parts 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 compatible with 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. The driving rod penetrates 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 frame 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 at the opposite side.

[0020] S2. Before palletizing, start the drive motor to drive the drive gear to rotate 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. When 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 the descent so that the product is located on the opposite side of the stacking arm.

[0022] S4, the servo motor controls the driving disk to rotate. At this time, the arc-shaped pull bar is close to the surface of the driving disk, and at the same time, the pull rod is pulled 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 press the adjustment bar upwards to move the bending part outwards. 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 bending part 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 downwards. At this time, the wheel hubs of the guide wheel and the conveying 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, and automatically control the servo motor to rotate counterclockwise. At this time, the arc-shaped pull bar slowly disengages from the drive disk, and 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, and at the same time, its bend slowly returns to its original position, and 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 stacking cart, its bottom end presses down on the straightening bar, so that a section of the connected stacking frame is swayed. Secondly, the distance between the opposite sides of the straightening bars on this section is smaller than the width of the product. After the product stacking is completed, the driving motor drives the main gear to move the translation table to both sides. At the same time, the driving rod drives the pushing frame to push the stacking cart outward, pushing the stacked products away from the equipment.

[0026] Beneficial effects:

[0027] Compared with the prior art, the automatic palletizing equipment and the method of using the same have the following beneficial effects:

[0028] 1. The present invention provides a stacking protection mechanism. When clamping the product, the two sides of the device will press the adjustment bar upward to the two 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 to the inner side of the stacking arm. When the bending part 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 to slide on the hub of the conveying wheel and the pull rope wrapped around the guide wheel is pulled to loosen, which is conducive to enhancing the vibration generated when the equipment moves to cause the product to slip from the clamping 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.

[0029] Second, the present invention sets up a stacking drive mechanism, and uses a servo motor to control the rotation of the driving disk. At this time, the arc-shaped pull bar is close to the surface of the driving 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 the contact with the driving disk, and at the same time, its other end pushes the stacking arm to both sides to release the product, which is conducive to the convenience of clamping the product. Secondly, it cooperates with the stacking protection mechanism to a certain extent.

[0030] 3. The present invention sets a controllable stacking anti-dumping mechanism, which uses a motor to drive the driving gear to rotate through the main gear, and at the same time, the driving gear drives the displacement table to slide to the opposite side through the driving bar until the driving bars are parallel to each other. When the driving bar moves, the main bevel gear drives the driving bevel gear to rotate. At this time, the pushing frame is moved backward as a whole due to the threaded connection of the driving rod. After the adjustment is completed, the stacking cart is pushed to the opposite side of the displacement table. Subsequently, when the product is out of contact with the stacking cart, its bottom end presses down the straightening bar, so that a section of the connected stacking frame is swayed, and then the distance between the opposite sides of the swaying bar on this section is less than the width of the product. After the product stacking is completed, the driving motor drives the main gear, so that the displacement table moves to both sides, and at the same time, the driving rod drives the pushing frame to push the stacking cart outward, pushing the stacked products away from the equipment, which is beneficial to prevent the products from tipping over during the stacking operation, and at the same time ensures that the stacking is neat, which is convenient for collective stacking in the later stage.

[0031] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0042] like Figure 1-8 As shown, the present invention provides a technical solution: an automatic palletizing device, comprising a conveyor belt 1 and a mounting frame 2, a palletizing driving mechanism 3 is fixedly connected to the middle position of the surface of the mounting frame 2, a group of left-right symmetrical moving grooves 4 are opened on the surface of the mounting frame 2, and a palletizing protection mechanism 5 is movably connected inside the moving grooves 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 rail 6, a palletizing cart 8 is arranged opposite to the front end of the guide rail 6, and the conveyor belt 1 is located on one side of one of the guide rails 6.

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, 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. 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 groove 4 and extends to the mounting frame 2. The top end, the width of the connection between the stacking arm 501 and the moving groove 4 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 also includes a pull rope 505, a guide wheel 506, a conveying wheel 507 and a bracket 508. The bracket 508 is respectively fixedly connected to the two sides of the top of the moving groove 4, and the guide wheel 506 is respectively rotatably connected to the opposite side of the bracket 508 through a torque spring. The conveying wheel 507 is located obliquely below the guide wheel 506 and is connected to the inside of the moving groove 4 by rotation. 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 wound around the hub of the guide wheel 506.

[0044] When clamping the product, its two sides will press upward to both sides of the adjustment bar 502, so that the bending part of the adjustment bar 502 moves outward, and at the same time, the arc bar 503 at the other end of the adjustment bar 502 drives the limit bar 504 to move laterally to 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 limit 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, so that it slides on the hub of the conveying wheel 507 and the pull rope 505 wrapped around the guide wheel 506 is pulled to loosen, which is conducive to enhancing the vibration generated when the equipment moves to cause the product to slip from the clamped state, and secondly to avoid 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.

[0045] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the stacking drive mechanism 3 includes a servo motor 301, a driving disk 302, an arc-shaped pull rod 303 and a pull rod 304. The output end of the servo motor 301 is fixedly connected to the driving disk 302 through a coupling. The arc-shaped pull rod 303 is point-symmetrical and is movably connected to the outer side of the driving disk 302 through a rotating shaft. The pull rods 304 are movably connected to one end of the arc-shaped pull rod 303 away from the driving disk 302 through a rotating shaft. The servo motor 301 is fixedly connected to the top surface of the mounting frame 2. The arc-shaped strip 503 is arranged in an arc shape and is adapted to the arc shape of the surface of the driving disk 302. The end of the pull rod 304 away from the arc-shaped pull rod 303 is movably connected to the top of the stacking arm 501 through a rotating shaft.

[0046] The driving disk 302 is controlled to rotate by the servo motor 301, at which 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 is used to rotate counterclockwise, at which time the arc-shaped pull bar 303 slowly breaks away from the contact with the driving disk 302, and 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. Secondly, it cooperates with the stacking protection mechanism 5 to a certain extent.

[0047] like 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. The driving gear 703 is provided with two and is symmetrically arranged to mesh 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 platform 705 is respectively fixedly connected to one end of the driving bar 704 away from the driving gear 703. The stacking rack 706 is symmetrically arranged and is respectively movably connected to the surface of the displacement platform 705 through a hinge. The stacking rack 706 is composed of several rectangular frames spliced ​​by limit hinges. The stacking rack 706 tilts to both sides due to the influence of the limit hinge. The connection of the stacking rack 706 is fixedly connected with a straightening bar 10, and the straightening bar 10 follows The stacking frame 706 is at a certain inclination angle, and two slide grooves 11 are provided at the bottom of the displacement platform 705, and the slide grooves 11 are arc-shaped and compatible with the guide rail 6. The displacement platform 705 is slidably connected to the guide rail 6 through the slide grooves 11, and the stacking anti-dumping mechanism 7 that can be controlled also includes 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 meshed with the main bevel gear 707, and the driving rod 709 penetrates the driving bevel gear 708 and extends to one side of the guide rail 6. The driving rod 709 is provided with a thread on the outer side near one end of the guide rail 6, and 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 stacking cart 8.

[0048] The motor drives the driving gear 703 to rotate through the main gear 702, and the driving gear 703 drives the displacement 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 cart 8 is pushed to the opposite side of the displacement platform 705, and then the product is separated from the contact with the stacking cart 8. When the product is palletized, the driving motor 701 drives the main gear 702, so that the displacement table 705 moves to both sides, and at the same time, the driving rod 709 drives the pushing frame 7010 to push the palletizing cart 8 outward, 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 ensure the neatness of the palletizing, which is convenient for collective stacking in the later stage.

[0049] Working principle: Install both ends of the mounting frame 2 to 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 at the opposite side. Start the drive motor 701 before palletizing 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 driven by the drive rod 709 due to the threaded connection. After the adjustment is completed, the stacking cart 8 is pushed to the opposite side of the displacement platform 705, the conveyor belt 1 is started to transport 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, and the servo motor 301 controls the driving disk 302 to rotate. At this time, the arc-shaped pull bar 303 is close to the surface of the driving disk 302, and the pull rod 304 is pulled to move to the opposite side. 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 both sides, so that the bending part moves outward, and the adjustment bar 50 The arc strip 503 at the other end drives the limit strip 504 to move to the inside of the stacking arm 501 on the opposite side. When the bending part of the adjustment strip 502 is completely parallel to the stacking arm 501, the limit strip 504 moves to the bottom of the product. When the adjustment strip 502 moves, the pull rope 505 is pulled downward to slide on the hub of the conveying wheel 507 and the pull rope 505 wound on the guide wheel 506 is pulled loose, and the clamped product is controlled 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 strip 303 slowly breaks away from the contact with the driving disk 302, and the other end thereof pushes to both sides. The stacking arm 501 releases 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 its bend slowly returns to its original position. Then the arc 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, so that a section of the connected stacking frame 706 is swayed. 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 driving motor 701 drives the main gear 702, so that the displacement table 705 moves to both sides. At the same time, the driving rod 709 drives the pushing frame 7010 to push the stacking cart 8 outward, pushing the stacked products away from the equipment.

10. A method for using the automatic palletizing equipment according to any one of claims 1 to 9, 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 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 displacement 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 cart (8) is pushed to the opposite side of the displacement 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 of the product, and then controls the mounting frame (2) 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, and the arc-shaped pull bar (303) is close to the surface of the driving disk (302), and at the same time pulls the pull rod (304) to move to the opposite side, and the pull rod (304) pulls the stacking arm (501) to clamp the product; S5. When clamping the product, the two sides of the product will press the adjusting bar (502) upwards and toward the two sides, so that the bending part of the adjusting bar (502) moves outwards, and 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 inner side 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 end of the product, and the pull rope (505) is pulled downwards while the adjusting bar (502) moves. At this time, the hubs of the guide wheel (506) and the conveying wheel (507) are pulled to slide, and at the same time, the pull rope (505) wrapped around the guide wheel (506) is pulled to be loosened; 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 which time the arc-shaped pull bar (303) slowly disengages from 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 clamped 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 cart (8), its bottom end presses down on the aligning bar (10), so that a section of the connected stacking frame (706) is swayed, and the distance between the opposite sides of the swaying bars on this section is smaller than the width of the product. After the product stacking is completed, the driving motor (701) drives the main gear (702), so that the displacement table (705) moves to both sides, and at the same time the driving rod (709) drives the pushing frame (7010) to push the stacking cart (8) outward, so that the stacked products are pushed away from the equipment.
