Description

Technical Field

[0001] The utility model relates to the technical field of palletizing, in particular to an automatic palletizer. Background Art

[0002] An automatic palletizer is an automated device mainly used for stacking cartons or other packaging materials that have been loaded into containers onto pallets or skids in a certain arrangement to achieve automatic stacking. It can stack multiple layers, facilitating transportation to the warehouse for storage using a forklift. This device is easy to operate and master, and can greatly reduce labor and labor intensity.

[0003] In the prior art, one type of grasping structure for an automatic palletizer to grasp goods such as cartons is to use a horizontally moving support plate that horizontally extends and retracts to reach under the edges of the carton on both sides to achieve grasping of the carton; another type is to use gripper arms that vertically flip on both sides of the carton to flip and clamp the carton on both sides to achieve grasping of the carton. The above grasping structures of the automatic palletizer both require a relatively large space on both sides of the carton for the grasping structure to move, which limits the application of the palletizer. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above problems in the prior art and provide an automatic palletizer.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic palletizer includes a grasping structure for grasping goods; the grasping structure includes a top plate, and vertical plates are connected to the lower sides of both ends of the top plate; two vertical shafts are rotatably connected to both ends of the grasping structure, the vertical shafts pass through the top plate and the vertical plates, and a support plate for supporting goods is connected to the lower ends of the vertical shafts; drive assemblies are arranged at both ends of the grasping structure, and the drive assemblies drive the two vertical shafts at the same end to rotate synchronously and reversely within a certain angle.

[0007] Further, the drive assembly includes a motor, a gear set, a horizontal shaft, and a bevel gear set. The motor is installed on the upper side of the end of the top plate, the horizontal shaft is rotatably installed on the upper side of the end of the top plate, the motor drives the horizontal shaft to rotate through the gear set, and bevel gear sets are arranged between both ends of the horizontal shaft and the two vertical shafts.

[0008] Further, the gear set includes a driving gear and a driven gear that mesh with each other. The driving gear is connected to the output shaft of the motor, the middle of the horizontal shaft passes through the driven gear and is connected to the driven gear; the bevel gear sets both include a driving bevel gear and a driven bevel gear that mesh with each other. The driving bevel gear is connected to the end of the horizontal shaft, and the driven bevel gear is connected to the upper end of the vertical shaft.

[0009] Further, protective covers are provided on the upper sides of both ends of the top plate, and the drive assembly is located inside the protective covers.

[0010] Furthermore, the rotation range of the vertical shaft is 90 degrees; one end of the support plate is connected to the vertical shaft, and the support plate has a first state parallel to the vertical plate and a second state perpendicular to the vertical plate.

[0011] Furthermore, a vertical through hole matching with the vertical shaft is arranged at the end of the grasping structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] In the utility model, the support plate rotates horizontally following the vertical shaft and can be hidden under the vertical plate. When the grasping structure moves vertically, the vertical plate and the support plate occupy less space on the side of the goods, improving the application range of the palletizer; when the support plate swings out, it can extend to the lower side of the edge of the goods to realize the grasping of the goods; the two vertical shafts and the support plates at the same end swing synchronously and in opposite directions, providing multi-point support to ensure the stability of the goods support.

[0014] In the utility model, the motor and the gear set can make the horizontal shaft reciprocate. The horizontal shaft realizes the synchronous and reverse rotation of the two vertical shafts at the same end through the bevel gear sets at both ends, and further makes the two support plates at the same end swing synchronously and in opposite directions, reasonably utilizing the space under the vertical plate, ensuring the length and spacing of the support plates, and making the support of the support plates to the goods stable after grasping; the driving assembly is protected by the protective cover.

[0027] Specific embodiments of the automatic palletizer provided by the present utility model:

[0028] Please refer to Figure 1-6 , an automatic palletizer, including a grasping structure 5 for grasping goods; in some embodiments, the automatic palletizer includes a track 1, gantries 2 for supporting the ends of the track 1 are arranged on the lower sides of both ends of the track 1, a translation seat 3 that translates along the track 1 is arranged on the track 1, a vertically lifting lifting column 4 is installed on the translation seat 3, a gear and a driving device for driving the gear to rotate are arranged on the translation seat 3, the lifting column 4 is vertically slidably connected to the translation seat 3, and a vertical rack for cooperating with the gear is arranged on one side of the lifting column 4; the grasping structure 5 is installed at the lower end of the lifting column 4.

[0029] By translating the seat 3 and the lifting column 4, the grasping structure 5 can be translated and lifted, and goods such as the cargo box on the conveyor can be grasped onto the pallet beside the conveyor for stacking. In some other embodiments, other structures can be provided to drive the grasping structure 5 of this embodiment to perform translations, liftings and other movements.

[0030] In this embodiment, the grasping structure 5 includes a top plate 501. The middle of the top plate 501 is connected to the lifting column 4. Vertical plates 502 are connected to the lower sides of both ends of the top plate 501. Two vertical shaft sleeves 503 are rotatably connected to both ends of the grasping structure 5. The shaft sleeves 503 pass through the top plate 501 and the vertical plates 502. Vertical through holes 512 are provided at the ends of the grasping structure 5 for cooperating with the shaft sleeves 503. Two through holes 512 are provided on each vertical plate 502. The two through holes 512 vertically penetrate the vertical plate 502 from both ends of the vertical plate 502 and extend to the upper side of the top plate 501, so that the shaft sleeves 503 can rotate in the through holes 512. In some embodiments, a vertical limiting structure for the shaft sleeves 503 can be provided in the through holes 512, or bearings can be provided to support the rotation of the shaft sleeves 503.

[0031] The lower ends of the shaft sleeves 503 are connected with support plates 504 for supporting goods. Driving components are provided at both ends of the grasping structure 5, and the driving components drive the two shaft sleeves 503 at the same end to rotate synchronously and reversely within a certain angle. In this embodiment, the rotation range of the shaft sleeves 503 is 90 degrees. One end of the support plate 504 is connected to the shaft sleeve 503. The support plate 504 has a first state parallel to the vertical plate 502 and a second state perpendicular to the vertical plate 502.

[0032] In the first state, the two support plates 504 are located below the vertical plate 502 between the shaft sleeves 503 and are hidden below the vertical plate 502. When the grasping structure 5 is lifted or lowered, the vertical plate 502 and the support plates 504 occupy a smaller lateral space on the side of the goods, and it is suitable for grasping goods in an environment where the reserved gap between goods is small. When the support plate 504 corresponds to the lower side of the goods, the support plate 504 swings to the second state, and the support plate 504 swings to extend below the edge of the goods. There are a total of four support plates 504 at both ends of the grasping structure 5, forming four support points, which can stably grasp and move the goods.

[0033] It should be noted that: Figure 1 The two states of the support plate 504 are shown simultaneously only for demonstration purposes; in actual use, the states of the support plates 504 at both ends of the grasping structure 5 need to be synchronized, that is, the four support plates 504 are simultaneously in the first state or the second state.

[0034] In this embodiment, the driving assembly includes a motor 505, a gear set, a horizontal shaft 508, and a bevel gear set. The motor 505 is installed on the upper side of the end of the top plate 501. The horizontal shaft 508 is rotatably installed on the upper side of the end of the top plate 501. A shaft seat for supporting the rotation of the horizontal shaft 508 is installed on the upper side of the top plate 501. The motor 505 drives the horizontal shaft 508 to rotate through the gear set. Bevel gear sets are provided between both ends of the horizontal shaft 508 and two vertical shafts 503.

[0035] Specifically, the gear set includes a driving gear 506 and a driven gear 507 that mesh with each other. The driving gear 506 is connected to the output shaft of the motor 505. The middle of the horizontal shaft 508 passes through the driven gear 507 and is connected to the driven gear 507. Each bevel gear set includes a driving bevel gear 509 and a driven bevel gear 510 that mesh with each other. The driving bevel gear 509 is connected to the end of the horizontal shaft 508, and the driven bevel gear 510 is connected to the upper end of the vertical shaft 503.

[0036] The motors 505 at both ends of the grasping structure 5 operate synchronously. The motor 505 rotates reciprocally within a certain angle, enabling the gear set and the bevel gear set to rotate reciprocally within a certain angle, which can achieve the reciprocating rotation of the vertical shaft 503 and the support plate 504 within 90 degrees, and further enable the support plate 504 to switch between the first state and the second state.

[0037] In this embodiment, shields 511 are provided on the upper sides of both ends of the top plate 501. The driving assembly is located inside the shields 511. In some embodiments, the shields 511 can be connected to the top plate 501 by means of bolt connection. The shields 511 can effectively protect the driving assembly.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
