Description

Technical Field

[0001] This application relates to the technical field of metal part pallets, and particularly to a palletizing machine. Background Art

[0002] With the continuous improvement of industrial automation, the palletizing machine, as a key device for realizing automatic stacking and palletizing of products, is widely used in many industries such as metal part production and transportation. The current palletizing machine uses a moving mechanical claw to grab the metal parts on the conveyor belt and place them on the pallet, and uses positioning technology to stack the metal parts from left to right on the pallet. After finishing one layer, another conveyor belt at the bottom of the pallet drives the pallet to step one grid, and starts to stack the next layer. It not only has a complex structure, but also this structure requires a high-precision positioning sensor to be integrated on the mechanical claw. When the placement position of the pallet deviates from the predetermined position, the parts cannot be accurately placed at the predetermined position on the pallet. As a result, the pallet cannot hold the predetermined number of parts, or when the predetermined number of parts are placed on the pallet, some parts will fall out of the pallet. Therefore, although the existing palletizing machine has a relatively high degree of automation, it is not convenient to use.

[0003] Regarding the above related technologies, the inventor believes that there are defects in the complex structure and inconvenient use of the existing palletizing machine. Summary of the Invention

[0006] By adopting the above technical solutions, the metal parts placed on the carrier plate can be toggled to one side for storage by setting the lever structure, and the toggling angle of the lever structure can be adjusted by adjusting the rotation angle of the cam, so that the metal parts can be stored on the carrier plate in an orderly manner.

[0013] Preferably, the transmission ratio of the first gear to the second gear is 1:1 or 1:2.

[0014] By adopting the above technical solution, the relative movement speed of the cam and the carrier plate can be controlled by setting the transmission ratio of the first gear to the second gear.

[0015] Preferably, the toggle lever includes a fixed portion connected to the hinge shaft and a telescopic portion connected to the fixed portion. The telescopic portion is formed by a plurality of rods with gradually decreasing rod diameters sleeved with each other. The inner rod of the two sleeved rods slides inside the outer rod, and a driving member for driving each rod to expand and contract is provided inside the telescopic portion.

[0018] By adopting the above technical solution, the automatic telescopic adjustment of the toggle rod is achieved through the nut and the screw, and the nut and the screw are connected by a fixed structure, which controls whether the nut and the screw are screwed together or fixed to limit the movement of the nut, thereby achieving the telescopic adjustment of the rod.

[0019] Preferably, the fixing structure includes an iron core arranged in the screw and an electromagnetic coil respectively arranged on each of the nuts.

[0020] By adopting the above technical solution, the nut and the screw are fixed and separated by the iron core and the electromagnetic coil.

[0024] By adopting the above technical solution, the adjustable clamp can move on the transverse track and the longitudinal track respectively to place the grasped metal parts in the same position, that is, the transverse track drives the adjustable clamp to move to the same position each time, and there is no need to locate other positions to stack the metal parts in order.

Detailed Description of the Embodiment

[0031] The following further describes the present application in detail in conjunction with the attached Figures 1 - 3 drawings.

[0032] An embodiment of the present application discloses a palletizing machine. Referring to Figures 1 - 3 , it includes a frame 1. A palletizing assembly 2 is provided on the frame 1. A conveying assembly 3 for conveying metal parts is provided at the end of the palletizing assembly 2, and a mechanical claw assembly 4 is provided on the front side of the palletizing assembly 2; the palletizing assembly 2 includes a carrier plate 21, a cam 22 rotatably connected to the carrier plate 21, a lever structure 23 connected to the cam 22, and a driving motor 24 for driving the cam 22 to rotate. The lever structure 23 is used to push the metal parts. The driving motor 24 is provided on the frame 1 and is connected to the camshaft 25 through a coupling. The camshaft 25 passes through the carrier plate 21 and is connected to the cam 22.

[0033] In this embodiment, by setting the lever structure 23, the metal parts placed on the carrier plate 21 can be toggled to one side for storage. By adjusting the rotation angle of the cam 22, the toggling angle of the lever structure 23 can be adjusted, so that the metal parts can be stored on the carrier plate 21 in an orderly manner. On the basis of simplifying the structure, this setting reduces the positioning accuracy requirements for the carrier plate 21. Even if there are deviations, the metal parts can be toggled to the predetermined position by the lever structure 23.

[0034] Specifically, the conveying assembly 3 adopts a conventional conveyor belt structure, including two rollers provided on the frame 1 and a conveyor belt connecting the two rollers. The two rollers are arranged at intervals and are rotatably connected to the frame 1. The shaft of one of the rollers is connected to the motor, and the other roller can be driven to rotate synchronously through the conveyor belt. One end of the conveyor belt is connected to the production mechanism of the metal parts, and the other end is provided with a parts prefabrication groove. After the conveyor belt conveys the metal parts to the prefabrication groove, the mechanical claw assembly 4 grabs the metal parts therein and moves them to the carrier plate 21. At this time, the mechanical claw assembly 4 only needs to move to a fixed position, without the need to use positioning technology to move the mechanical claw to the corresponding position above the carrier plate 21 to stack the metal parts on the carrier plate 21 in sequence.

[0035] In some embodiments, the lever structure 23 includes a toggling lever 231, a hinge shaft 232 rotatably connected to the carrier plate 21, and a spring 233 wound around the hinge shaft 232. One side of the toggling lever 231 close to the cam 22 is connected to the hinge shaft 232, and the end is in contact with the convex part of the cam 22. The hinge shaft 232 is rotatably connected to the carrier plate 21. One end of the spring 233 is connected to the hinge shaft 232, and the other end is connected to the carrier plate 21.

[0036] In this embodiment, the toggling lever 231 is used to toggle the metal parts. The toggling lever 231 is connected to the carrier plate 21 through the hinge shaft 232. When the cam 22 rotates, the toggling lever 231 can be driven to swing through contact with the cam 22. By its swing, the metal parts can be toggled to one side, and the swing angle of the toggling lever 231 can be controlled by adjusting the rotation angle of the cam 22, so as to toggle the metal parts to different positions for stacking. In addition, the cam 22 can rotate forward and backward alternately to toggle the metal parts to the left and right sides respectively, so that the metal parts can be stacked on the left and right sides of the carrier plate 21 respectively on the basis that the carrier plate 21 does not move.

[0037] Specifically, a spring 233 is provided on the hinge shaft 232 to reset the toggle lever 231. When the cam 22 drives the toggle lever 231 to swing, the spring 233 will be stretched. After the convex part of the cam 22 rotates past, that is, when the cam 22 is not in contact with the toggle lever 231, the elastic force of the spring 233 will drive the hinge shaft 232 to reverse, thereby realizing the reset of the toggle lever 231 and waiting for the stacking of the next metal part. In addition, a roller can also be provided at the end of the toggle lever 231. When the cam 22 rotates, the relative rolling between the roller and the edge position of the convex part drives the toggle lever 231 to swing.

[0038] In some embodiments, the carrier plate 21 is provided with positioning grooves 26 arranged in an array.

[0039] In this embodiment, the positioning grooves 26 are provided on the carrier plate 21 to place metal parts. By adjusting the rotation angle of the cam 22, the swing angle of the toggle lever 231 can be adjusted, so that the metal parts can be respectively toggled into the positioning grooves 26. Since the depth of the positioning grooves 26 is adapted to the thickness of the metal parts, after the metal parts enter the positioning grooves 26, their tops are flush with the end face of the carrier plate 21. In this way, the metal parts can slide over its surface. During operation, the toggle lever 231 first toggles the metal parts into the positioning groove 26 closest to it. Then, when toggling the metal parts to a slightly farther positioning groove 26, the metal parts can slide over its surface and then enter the predetermined positioning groove 26, avoiding falling into the slightly closer groove before moving to the slightly farther positioning groove 26.

[0040] In some embodiments, the code disc assembly 2 further includes a drive shaft 27 rotatably connected to the frame 1, a first gear 28 provided on the drive shaft 27, and a second gear 29 provided on the cam shaft 25. The first gear 28 meshes with the second gear 29, and the drive shaft 27 is connected to the carrier plate 21.

[0041] In this embodiment, by providing the mutually meshing first gear 28 and second gear 29, the synchronous rotation of the carrier plate 21 and the cam 22 can be realized. Since the cam 22 drives the toggle lever 231 to swing counterclockwise when rotating, the rotation direction of the carrier plate 21 is also opposite to the swing direction of the toggle lever 231. At this time, the positioning grooves 26 on the carrier plate 21 move towards each other, which is more conducive to toggling the metal parts into the positioning grooves 26.

[0042] In some embodiments, the transmission ratio of the first gear 28 to the second gear 29 is 1:1 or 1:2.

[0043] In this embodiment, the relative movement speed of the cam 22 and the carrier plate 21 can be controlled by setting the transmission ratio of the first gear 28 and the second gear 29. For example, when the transmission ratio is 1:2, the cam 22 rotates twice when the carrier plate 21 rotates one circle, that is, the toggle lever 231 can be toggled twice when the carrier plate 21 rotates one circle, thereby improving the stacking rate.

[0044] Specifically, the driving shaft 27 and the carrier plate 21 are detachably connected, and the cam shaft 22 and the carrier plate 21 are also detachably connected, so that it is easy to replace a new carrier plate 21 after the metal parts are fully stacked.

[0045] Specifically, a lifting mechanism can be set under the carrying plate 21, and a weight sensor is set on the lifting mechanism to detect whether the carrying plate 21 is full of metal parts. After it is full, the lifting mechanism drives the carrying plate 21 to descend, and then the staff removes the carrying plate 21 and the lifting mechanism rises to its original position again, and a conveyor belt structure is set on the side of the lifting mechanism away from the mechanical claw assembly 4. When the carrying plate 21 descends, the conveyor belt structure transports an empty carrying plate 21 to the lifting structure, and connects the carrying plate 21 to the drive shaft 27 and the cam 22 shaft through a detachable structure.

[0046] In some embodiments, the toggle rod 231 includes a fixed portion 2311 connected to the hinge shaft 232 and a telescopic portion connected to the fixed portion 2311. The telescopic portion is formed by a plurality of rod members 2312 with successively decreasing rod diameters being nested with each other. The inner rod of the two nested rod members 2312 is slidably connected to the outer rod, and a driving member is provided inside the telescopic portion to drive each rod member 2312 to telescope.

[0047] In this embodiment, a retractable toggle rod 231 is provided to achieve the stacking of metal parts into different circles / layers. If the carrier plate is circular, a circular path with different radii is drawn with the center of the circle as the center, and a plurality of positioning grooves 26 are arranged in an array on each path. The toggle rod 231 of the same length can push the metal parts into the positioning grooves 26 located in the same circle, while the positioning grooves 26 located in different layers require toggle rods 231 of different lengths. If the carrier plate is rectangular, the same principle is used, and thus the toggle rod 231 is provided as a structure with multiple rods 2312 interconnected to adjust its length.

[0048] In some embodiments, the driving member includes a rotating motor 2313 disposed inside the rod 2312 and close to the fixed portion 2311, a screw 2314 connected to the output shaft of the rotating motor 2313, and a plurality of nuts 2315 screwed onto the screw 2314, each nut 2315 being connected to the inner wall of each of the remaining rods 2312, and a fixing structure being provided between the nut 2315 and the screw 2314.

[0049] In this embodiment, a screw 2314 and a nut 2315 are provided to realize the automatic extension and retraction of the toggle rod 231, and the rod 2312 close to the fixed portion 2311 is set as the control end, and the remaining rods 2312 are used as the extension end. Therefore, a rotating motor 2313 and a screw 2314 connected to the rotating motor 2313 are provided in the control end. The screw 2314 can be connected to the inner wall of the control end through a bearing, and the inner walls of the remaining rods 2312 are respectively screwed to the screw 2314 through nuts 2315. At this time, the screw 2314 is screwed to the inner wall of the control end. The rotation of 314 can be converted into linear motion of the nut 2315. Therefore, the movement of the nut 2315, that is, the automatic extension and retraction of each rod 2312, can be controlled by controlling the rotation of the rotating motor 2313. In addition, the rods 2312 at the telescopic ends need to move in sequence. Therefore, a fixed structure is set between the nut 2315 and the screw 2314. When the rod 2312 is extended or retracted, the nut 2315 and the screw 2314 are screwed together, and the corresponding rod 2312 begins to extend and retract, and the remaining rods 2312 do not move.

[0050] In some embodiments, the fixing structure includes an iron core 2316 disposed in the screw 2314 and an electromagnetic coil 2317 respectively disposed on each nut 2315.

[0051] In this embodiment, since the electromagnetic coil 2317 and the iron core 2316 are used to fix and separate the screw 2314 and the nut 2315, when each rod 2312 at the telescopic end needs to be extended, the electromagnetic coil 2317 on the nut 2315 located at the rightmost end (i.e., the end away from the fixed part 2311) is powered off, and the electromagnetic coils 2317 on the remaining nuts 2315 are energized, and the corresponding nuts 2315 are separated from the screw 2314. The nut 2315 can move with the rotation of the screw 2314, and the rod 2312 is extended. When it reaches the maximum length, its adjacent rod 2312 repeats the above action and starts to extend. When it needs to be shortened, the above action is repeated in the reverse direction.

[0052] Specifically, a displacement sensor is provided at the fixed part 2311 to monitor the length of the telescopic part in real time, and control the rotating motor 2313 to stop working when the predetermined length is reached, and contact switches are provided at the left and right ends of each rod 2312. When the rod 2312 is extended to the maximum length, the nut 2315 contacts the contact switch, and the contact switch sends a power-off signal. The electromagnetic coil 2317 on the nut 2315 is energized, and the nut 2315 is fixed to the screw 2314 and rotates as the screw 2314 rotates.

[0053] In some embodiments, a shift rod 234 is provided at one end of the toggle rod 231 away from the hinge shaft 232 , and the axial direction of the shift rod 234 is perpendicular to the axial direction of the toggle rod 231 .

[0054] In this embodiment, the shift rod 234 is provided to change the moving route of the metal parts on the carrier plate. Since the mechanical claw assembly 4 places the metal parts near the edge of the carrier plate, it is convenient to move the toggle rod 231 to move the metal parts into the positioning groove 26 of the outermost circle. For the positioning groove 26 of the inner circle, the shift rod 234 is needed to change the direction. When in use, the toggle rod 231 is extended so that the end face of the shift rod 234 close to the center of the circle contacts the end face of the metal parts away from the center of the circle. Then, the cam 22 rotates while controlling the toggle rod 231 to shorten, thereby controlling the metal parts to move toward the center of the circle while moving them.

[0055] In some embodiments, the mechanical claw assembly 4 includes a transverse rail 41 provided on the frame 1, a longitudinal rail 42 slidably connected to the transverse rail 41, a slider 44 slidably connected to the longitudinal rail 42, and an adjustable clamp 43 provided on the slider 44. The two ends of the transverse rail 41 extend to the end of the conveying assembly 3 and the middle position of the supporting plate 21 respectively.

[0056] In this embodiment, the mechanical claw assembly 4 uses an adjustable jaw to grasp the metal parts. The adjustable jaw 43 uses a pneumatic method to adjust the distance between the two claws. For example, the cylinder is used to control the claws to move toward or away from each other. Then, the adjustable jaw 43 drives the metal parts to move on the horizontal track 41 to the top of the carrier plate, and then starts to move on the longitudinal track 42 until the metal parts are placed on the carrier plate. This structure no longer needs to control the adjustable jaw 43 to move to different positions of the carrier plate to stack the metal parts, making the structure simpler and more convenient to use.

[0057] The working principle of a coding machine in the present application is as follows: after the conveyor belt conveys the metal parts to the prefabricated groove on it, the adjustable clamping claw 43 drives the metal parts to move on the transverse track 41 to the top of the carrier plate, and then starts to move on the longitudinal track 42 until the metal parts are placed on the carrier plate. Then, the drive motor 24 is started, driving the cam 22 and the carrier plate to start rotating, and the raised part of the cam 22 drives the toggle rod 231 to swing, and the metal parts are toggled into the corresponding positioning groove 26. The swing angle of the toggle rod 231 is controlled by adjusting the rotation angle of the cam 22, so that the metal parts are The parts are moved to different positions for stacking. After the metal parts are moved, the toggle rod 231 is reset under the drive of the spring 233 and waits for the next metal part. In order to stack the metal parts in different positioning grooves 26 of different circle layers, the toggle rod 231 is set to a telescopic structure, and a gear rod 234 is set at the end. When in use, the toggle rod 231 is extended so that the end face of the gear rod 234 close to the center of the circle contacts the end face of the metal part away from the center of the circle. Then, the cam 22 rotates while controlling the toggle rod 231 to shorten, and control it to move toward the center of the circle while toggling the metal parts.

[0058] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
