Description

Technical Field

[0001] This utility model relates to the field of automatic transfer device technology, specifically an automatic transfer and circulation device for palletizing trays. Background Technology

[0002] Palletizing trays are used for batch installation and transfer of workpieces. The transfer process is as follows: 1. A pallet filled with workpieces is placed on the pallet rack at the unloading station; 2. A cylinder pushes the pallet, causing it to enter the gripping station; 3. The robotic arm at the gripping station transfers the workpieces one by one into the processing equipment; 4. After all the workpieces in the pallet have been gripped, they enter the waiting-to-recovery station; 5. A cylinder at the recovery station grips the pallet on the waiting-to-recovery station and places it onto the pallet rack at the recovery station.

[0003] Because the palletizing tray needs to move in two directions, two structures are required: one for pushing the palletizing tray and the other for gripping the palletizing tray. This results in a complex structure and high cost.

[0004] Therefore, how to overcome the above-mentioned defects has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses an automatic transfer and circulation device for palletizing trays.

[0006] This utility model provides an automatic transfer and circulation device for palletizing trays. Two horizontally and symmetrically arranged transfer cylinders are installed at both the unloading station and the recycling station, and gripping plates are installed at their drive ends.

[0007] A gripping cylinder is installed on the gripping plate, and its driving direction is horizontal and perpendicular to the driving direction of the transfer cylinder.

[0008] The drive end of the gripping cylinder is equipped with a claw plate, and the claw plate has a U-shaped groove; the openings of the U-shaped grooves on the two claw plates at the same station are opposite to each other;

[0009] The pallet is connected to gripping columns at both ends in the direction of the transfer cylinder drive, and the outer ends of the gripping columns are connected to radially protruding limiting plates.

[0010] U-shaped slot clamps the gripping column.

[0011] When the cylinder extends to push the pallet, the limiting plate becomes the force point of the claw plate, enabling the pallet to be pushed stably; when the cylinder retracts to pull the pallet, the side of the pallet connected to the gripping column becomes the force point of the claw plate, enabling the pallet to be pulled stably. With the above configuration, the pallet can be pushed and pulled by the same gripping component at the drive end of the transfer cylinder, which not only simplifies the structure but also reduces the cost.

[0012] To facilitate the assembly and disassembly of the gripping column, the following design is implemented: the gripping column includes a stud, a locking plate, a locking post, and a limiting plate connected in sequence; the stud is threadedly connected to the palletizing plate; the locking plate is close to the palletizing plate to achieve locking and fixation; and the U-shaped groove engages with the locking post.

[0013] Since the palletizing trays are stacked vertically on the palletizing frame, if the transfer cylinder is driven to rise and fall, the air pipes connecting the transfer cylinder and the gripping cylinder must also rise and fall simultaneously. This would make the structure more complex and the air pipes more prone to damage. Based on this, a further improvement is made: both the unloading station and the recycling station are equipped with lifting plates, and the palletizing frame is set at the top of the lifting plate; both the unloading station and the recycling station are equipped with lifting components to drive the lifting plate to rise and fall.

[0014] Furthermore, this utility model includes a feeding station, a gripping station, a recycling station, and a recycling station arranged sequentially.

[0015] The gripping station and the recycling station are set on a horizontally arranged pallet base; by moving the pallet base horizontally, it switches between the gripping station and the recycling station, and the pallet on the gripping station is transferred to the recycling station.

[0016] Because the palletizing tray is unstable and prone to shifting after entering the gripping station, the following improvements are made: the base of the pallet is equipped with upward-protruding positioning posts; the palletizing tray is equipped with positioning holes for engaging the positioning posts.

[0017] Because the palletizing tray is obstructed by the positioning posts during movement, making it difficult to accurately engage the posts, a further improvement is made: a bracket driven by a lifting cylinder is installed on the pallet base; the bracket supports the pallet. With this configuration, before the pallet enters the gripping station, the lifting cylinder drives the bracket upwards; when the pallet is pushed onto the bracket, the lifting cylinder descends, allowing the pallet to engage with the positioning posts.

[0018] Since the palletizing tray slides along the bracket when it moves, it is prone to wear. Therefore, a further improvement is made by installing pulleys on the bracket; the pulleys are in rolling connection with the lower end face of the palletizing tray.

[0019] The beneficial effects of this utility model are: the U-shaped groove engages with the gripping column, and when the cylinder extends to push the pallet, the limiting plate becomes the force point of the claw plate, enabling the pallet to be pushed stably; when the cylinder retracts to pull the pallet, the side of the pallet connected to the gripping column becomes the force point of the claw plate, enabling the pallet to be pulled stably; with the above configuration, the drive end of the transfer cylinder can use the same gripping component to realize the pushing and pulling of the pallet, which not only simplifies the structure but also reduces the cost.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] like Figure 1 and Figure 2 As shown, this utility model discloses an automatic transfer and circulation device for palletizing trays 6, which includes a feeding station, a gripping station, a waiting-to-recycle station, and a recycling station arranged in sequence.

[0029] Both the unloading station and the recycling station are equipped with two horizontally and symmetrically arranged transfer cylinders 1. The specific installation structure is as follows: the unloading station and the recycling station are set on both sides of the same bracket 18. The upper end face of the bracket 18 is provided with a vertically upward extending mounting frame, and the transfer cylinder 1 is mounted on the mounting frame.

[0030] like Figure 3 As shown, a gripping plate 2 is installed on the drive end of the transfer cylinder 1, and a gripping cylinder 3 is installed on the gripping plate 2. Its driving direction is horizontal and perpendicular to the driving direction of the transfer cylinder 1. A connecting plate 22 is installed on the drive end of the gripping cylinder 3, and a claw plate 4 is vertically arranged on the outer side of the connecting plate 22. The claw plate 4 has a U-shaped groove 5, and the openings of the U-shaped grooves 5 on the two claw plates 4 at the same station are opposite each other.

[0031] The palletizing tray 6 is connected to gripping columns 7 at both ends in the driving direction of the transfer cylinder 1. The outer ends of the gripping columns 7 are connected to radially protruding limiting plates 8, and U-shaped grooves 5 are used to engage the gripping columns 7.

[0032] To facilitate the disassembly and assembly of the gripping column 7, such as Figure 5 As shown, the gripping column 7 includes a stud 71, a locking plate 72, a locking plate 73, and a limiting plate 8 connected in sequence; the stud 71 is threadedly connected to the pallet 6; the locking plate 72 is close to the pallet 6 to achieve locking and fixing; the U-shaped groove 5 engages with the locking plate 73.

[0033] Since the palletizing trays 6 are stacked vertically on the palletizing frame 10, both the unloading station and the recycling station are equipped with lifting plates 9 mounted on the bracket 18, with the palletizing frame 10 positioned above the lifting plates 9. Both the unloading station and the recycling station are equipped with lifting components 24 mounted on the bracket 18 to drive the lifting plates 9 to move up and down. In this embodiment, the lifting component 24 is an electric cylinder; in other embodiments, it can also be a pneumatic cylinder or other linearly moving components. With this configuration, by lifting the lifting plates 9, the palletizing trays 6 on the palletizing frame 10 at the unloading station can be pushed one by one into the gripping station, and the palletizing trays 6 at the recycling station can be pulled one by one into the palletizing frame 10 at the recycling station.

[0034] The gripping station is equipped with a robotic arm 20, which sequentially transfers the workpieces on the gripping station into the processing equipment 19 for processing.

[0035] The gripping station and the recycling station are set on a horizontally arranged pallet base 12. The pallet base 12 moves horizontally, switching between the gripping station and the recycling station, and transferring the pallet 6 from the gripping station to the recycling station. The specific structure for the horizontally movable pallet base 12 is as follows: a connecting frame 21 is connected to the processing equipment 19, and a horizontally arranged mounting base 23 is installed on the upper surface of the connecting frame 21. A lead screw pair and a linear guide are installed on the upper surface of the mounting base 23. One end of the lead screw in the lead screw pair is driven to rotate by a motor. The lower end of the pallet base 12 is fixedly connected to the lead screw nut in the lead screw pair and also fixedly connected to the slider in the linear guide.

[0036] The base 12 of the pallet is provided with an upwardly protruding positioning post 13; the pallet 6 is provided with a positioning hole 14 for engaging the positioning post 13, so that the position of the pallet 6 is more stable and will not move, and the robot arm 20 can grasp the workpiece more accurately.

[0037] Because the palletizing tray 6 is obstructed by the positioning post 13 when it moves, it is difficult to accurately engage the positioning post 13. Therefore, as Figure 4As shown, a bracket 16, driven to rise and fall by a lifting cylinder 15, is also installed on the pallet base 12; the bracket 16 is used to support the pallet 6. With this configuration, before the pallet 6 enters the gripping station, the lifting cylinder 15 drives the bracket 16 to rise, and when the pallet 6 is pushed onto the bracket 16, the lifting cylinder 15 descends, so that the pallet 6 can engage with the positioning post 13.

[0038] The bracket 16 is equipped with a pulley 17; the pulley 17 is in rolling connection with the lower end face of the pallet 6 to prevent wear on the pallet 6.

[0039] The working principle of this embodiment is as follows: the U-shaped groove 5 engages with the gripping column 7. When the cylinder extends to push the pallet 6, the limiting plate 8 becomes the force point of the claw plate 4, so that the pallet 6 can be pushed stably. When the cylinder retracts to pull the pallet 6, the side of the pallet 6 connected to the gripping column 7 becomes the force point of the claw plate 4, so that the pallet 6 can be pulled stably.

[0040] Compared with the prior art, the beneficial effect of this embodiment is that the drive end of the transfer cylinder 1 can realize the pushing and pulling of the palletizing tray 6 by using the same gripping component, which not only simplifies the structure but also reduces the cost.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
