Description

Technical Field

[0001] The present application relates to the technical field of palletizing equipment, and in particular to an automatic palletizing device for container corner fittings. Background Art

[0002] Container corner fittings are also called box corners and lifting corners. They are mainly used at the corners of containers and play a key role in the lifting, handling, fixing, stacking and fastening of containers. Container corner fittings are generally hexahedral in structure and are usually made of high-strength steel to ensure that the corner fittings have sufficient strength and durability.

[0003] During the production process of container corner fittings, the finished container corner fittings will be placed on a conveyor belt, which will transport the container corner fittings. At this time, a stacking device is often used to transfer the container corner fittings from the conveyor belt to a pallet, and then stack the container corner fittings on the pallet.

[0004] At present, common palletizing devices mainly include a power mechanism and a gripping mechanism. The gripping mechanism is used to grip the corner pieces of containers, and the power mechanism is used to drive the gripping mechanism to reciprocate between the conveyor belt and the pallet, so as to palletize the corner pieces of containers on the conveyor belt onto the pallet. Among them, the power mechanism usually adopts a multi-axis drive platform or a six-axis robot composed of multiple linear modules, and the gripping mechanism usually adopts a pneumatic gripper or a vacuum suction cup or an electromagnetic suction cup.

[0005] With regard to the above-mentioned related technologies, since the conveyor belt realizes continuous transportation of container corner fittings, when the stacking device grabs the container corner fittings on the conveyor belt, the conveying speed of the conveyor belt is in a normal state. When the stacking device transfers the container corner fittings to the pallet, the conveyor belt often needs to reduce the conveying speed or suspend transportation to prevent the container corner fittings on the conveyor belt from missing the stacking device. This results in the speed at which the stacking device transfers the container corner fittings restricting the conveying speed of the conveyor belt. In order to ensure that there is no accumulation of container corner fittings on the conveyor belt, the production efficiency of the container corner fittings needs to be adjusted, which makes the transfer speed of the stacking device affect the production efficiency of the container corner fittings. Summary of the invention

[0006] The present application provides an automatic stacking device for container corner fittings, the purpose of which is to reduce the impact of the stacking device on the production efficiency of container corner fittings.

[0007] The automatic stacking device for container corner pieces provided in this application adopts the following technical solution:

[0008] A device for automatically stacking container corner fittings, comprising a conveyor belt; a pallet; a temporary storage mechanism, comprising an installation pipe rack, a material pushing assembly and a material storage assembly, wherein the material pushing assembly and the material storage assembly are both located in the installation pipe rack, the material pushing assembly is located on one side of the conveyor belt in the length direction, and the material storage assembly is located directly above the material pushing assembly, the conveyor belt is used to convey the container corner fittings to the material pushing assembly, the material pushing assembly is used to push the container corner fittings into the material storage assembly, and the material storage assembly is used to store the container corner fittings; a transfer mechanism, comprising a fixed frame, a grabbing manipulator and a power assembly, the conveyor belt, the pallet and the temporary storage mechanism are all located in the fixed frame, the power assembly is arranged on the fixed frame, the grabbing manipulator is connected to the power assembly, the grabbing manipulator is used to grab the container corner fittings, and the power assembly is used to drive the grabbing manipulator to reciprocate between the pallet and the material storage assembly.

[0009] By adopting the above technical solution, firstly, the conveyor belt realizes the conveyance of the container corner fittings. The pallet carries the container corner fittings. The transfer mechanism can grab the container corner fittings and transfer them to the pallet through the cooperation of the fixed frame, the grabbing manipulator and the power assembly, which can realize the stacking of the container corner fittings and thus meet the function of the stacking device. Secondly, the temporary storage mechanism cooperates with the mounting frame, the pushing assembly and the storage assembly. When the conveyor belt transports the container corner fittings to the mounting frame, the pushing assembly can push the container corner fittings into the storage assembly, which can realize the temporary storage of the container corner fittings.

[0010] Since the temporary storage mechanism can temporarily store the corner fittings of the container, when the transfer mechanism transfers the corner fittings of the container to the pallet, the temporary storage mechanism temporarily stores the corner fittings of the container transported on the conveyor belt, which enables the conveyor belt to maintain a normal conveying speed. After the transfer mechanism places the corner fittings of the container on the pallet, the transfer mechanism moves to the temporary storage mechanism, and the temporary storage mechanism can provide multiple corner fittings of the container to the transfer mechanism, so that the transfer mechanism can quickly obtain multiple corner fittings of the container at one time. On the one hand, the temporary storage mechanism realizes the rapid loading of the transfer mechanism, thereby improving the transfer efficiency of the transfer mechanism, and then improving the palletizing efficiency of the palletizing device. On the other hand, the temporary storage mechanism can be quickly emptied, so that the temporary storage mechanism can continue to work.

[0011] Since the temporary storage mechanism serves as a buffer between the conveyor belt and the transfer mechanism, the restriction of the transfer speed of the transfer mechanism on the conveying speed of the conveyor belt can be reduced, and the influence of the stacking device on the production efficiency of the container corner fittings can be reduced, thereby ensuring the production efficiency of the container corner fittings.

[0012] In addition, since the grabbing robot reciprocates between the storage assembly and the pallet, the position where the grabbing robot grabs the container corner pieces and the position where the container corner pieces are placed are fixed, which can improve the accuracy and reliability of palletizing.

[0013] Optionally, the material pushing assembly includes a storage plate, which is slidably connected to the mounting pipe rack in a vertical direction, and a material pushing drive is arranged under the storage plate, and the material pushing drive is used to drive the storage plate to move in the vertical direction; the material storage assembly includes a material guide tube, which is connected to the mounting pipe rack, the material guide tube is vertically arranged, the storage plate and the material guide tube are spaced apart in the vertical direction, the material guide tube is located directly above the storage plate, and the storage plate is plugged and matched with the material guide tube in the vertical direction; a plurality of support members are arranged on the inner side wall of the material guide tube, and the support members include a support block, a support groove is opened on the inner side wall of the material guide tube, the support block is plugged and matched with the support groove, and an introduction drive member is arranged on the support block, and the introduction drive member is used to drive the support block to move in the depth direction of the support groove.

[0014] By adopting the above technical solution, the material pushing assembly enables the material placing plate to move in the vertical direction through the arrangement of the material placing plate and the material pushing driving member, which satisfies the function of the material pushing assembly. The material storage assembly enables the conveyor belt to convey the container corner fittings to the material placing plate through the arrangement of the material guide pipe, because the material placing plate and the material guide pipe are arranged at intervals in the vertical direction, and the material placing plate and the material guide pipe are plugged and matched in the vertical direction, which enables the material placing plate to push the container corner fittings into the material guide pipe. The support piece in the material guide pipe cooperates with the support block and the introduction driving member, and when the material placing plate pushes the container corner fittings into the material guide pipe, the support block retracts into the support groove, and at this time, the material placing plate can push the container corner fittings to the top of the support block, and then the support block extends out of the support groove, the support plate descends and resets, and the container corner fittings will descend to contact the support block, and a number of support blocks support the container corner fittings, which enables the container corner fittings to be stored in the material guide pipe. With such a structure, when the pushing assembly pushes a plurality of container corner fittings into the material guide tube in sequence, the plurality of container corner fittings will be stacked in the material guide tube, thus enabling the storage of container corner fittings.

[0015] Optionally, the support block is slidably connected to the inner side wall of the support groove along the depth direction of the support groove; the introduction drive member includes a return spring, the return spring is located in the support groove, the return spring is axially arranged along the depth direction of the support groove, one end of the return spring is connected to the inner side wall of the support groove, and the other end is connected to the support block; an introduction slope is arranged on the lower side of the support block, and the introduction slope is arranged to extend downwardly and inclined toward a side corresponding to the return spring.

[0016] By adopting the above technical solution, the introduction drive member is provided with an introduction slope. Since the introduction slope is provided at the lower side of the support block, when the storage plate pushes the container corner piece into the guide tube, the container corner piece will first contact the introduction slopes of several support blocks. At this time, under the action of the introduction slope, the support blocks will all retract into the corresponding support grooves, which enables the storage plate to push the container corner piece to the top of several support blocks. The introduction drive member is provided with a reset spring. When the support block retracts into the corresponding support groove, the reset spring is compressed. After the container corner piece moves to the top of the support block, the reset spring drives the support block to reset, and the support block pops out of the corresponding support groove, which enables the support block to automatically support the container corner piece. Therefore, the introduction drive member is provided with the introduction slope and the reset spring, so that the support block can automatically respond to the storage of the container corner piece, which can improve the working efficiency of the temporary storage mechanism.

[0017] Optionally, the temporary storage mechanism also includes a stacking assembly, which includes a plurality of stacking guide rods, the stacking guide rods are located above the material guide pipe, the stacking guide rods are vertically arranged, the lower ends of the stacking guide rods are connected to the material guide pipe, the plurality of the stacking guide rods are arranged in a matrix, and stacking channels are formed between the plurality of the stacking guide rods, and the lower ends of the stacking channels are connected to the material guide pipe.

[0018] By adopting the above technical solution, the stacking assembly can establish a stacking channel above the guide pipe by setting a plurality of stacking guide rods, and the stacking channel is connected to the guide pipe, so that the container corner pieces stored in the guide pipe can be stored in the stacking channel, so that the temporary storage mechanism can store more container corner pieces. In addition, the stacking guide rods limit and guide the stacked container corner pieces to prevent the stacked container corner pieces from tipping over, thereby enhancing the stability and safety of the temporary storage mechanism.

[0020] By adopting the above technical solution, the discharging assembly is arranged by the coordination of the discharging ring, the discharging electromagnet and the discharging driving part. The discharging ring surrounds the outside of the stacking channel. When the container corner pieces are stacked in the stacking channel, the container corner pieces are located in the discharging ring. The discharging ring can magnetically fix the corresponding container corner pieces through the discharging electromagnet. At this time, under the drive of the discharging driving part, the discharging ring can transport the container corner pieces upward along the stacking channel. When the grabbing manipulator needs to grab the container corner pieces, the discharging assembly can transport the container corner pieces in the stacking channel upward, and then transport the container corner pieces to the grabbing manipulator, which can realize automatic loading of the grabbing manipulator.

The connecting frame realizes the connection between the mounting plate and the power assembly, and the mounting plate is used to fix the grabbing electromagnet. Since there are several grabbing electromagnets, each grabbing electromagnet can magnetically fix a container corner piece, which enables the grabbing robot to grab multiple container corner pieces, which can improve the transfer efficiency of the stacking device.

[0023] Optionally, the grasping robot includes a connecting frame, a mounting plate and a plurality of grasping electromagnets, the connecting frame is connected to the power assembly, the mounting plate is connected to the connecting frame, the mounting plate is vertically arranged, a plurality of the grasping electromagnets are arranged on one side of the mounting plate, and the plurality of the grasping electromagnets are arranged in sequence and spaced apart in the vertical direction.

[0024] By adopting the above technical solution, the grabbing manipulator cooperates with the vertically arranged mounting plate and a plurality of grabbing electromagnets. Since the plurality of grabbing electromagnets are arranged in sequence and at intervals along the vertical direction, when the power component drives the mounting plate to approach the stacking channel, the plurality of container corner fittings stacked in the stacking channel and the plurality of grabbing electromagnets on the mounting plate are arranged one by one in correspondence. When the grabbing electromagnets are energized, each grabbing electromagnet can synchronously magnetically fix the corresponding container corner fitting, which enables the grabbing manipulator to grab multiple container corner fittings at the same time, thereby increasing the speed at which the grabbing manipulator grabs the container corner fittings, thereby further improving the transfer efficiency of the stacking device.

When the placement plate 321 is located in the material guide tube 331, the placement plate 321 and the inner side wall of the material guide tube 331 are spaced apart.

[0051] Through the cooperation of the pushing assembly 32 and the storing assembly 33, when the conveyor belt 1 transports the container corner fitting 100 to the installation pipe rack 31, the container corner fitting 100 enters the feed cavity 313 through the feed port 312, and the container corner fitting 100 moves to the placement plate 321.

The driving direction of the switching driving member 433 is arranged in the vertical direction. The switching driving member 433 is arranged on the base frame 431, and the driving end of the switching driving member 433 is connected to the ring frame 432. In this embodiment, the switching driving member 433 adopts a cylinder or a hydraulic cylinder.

[0064] By switching the drive of the driving member 433, when the grabbing manipulator 41 needs to grab the container corner fitting 100, the ring frame 432 rises, which can increase the height of the grabbing manipulator 41 and the power assembly 42, thereby facilitating the grabbing manipulator 41 to grab the container corner fitting 100. When the grabbing manipulator 41 needs to stack the container corner fitting 100 on the pallet 2, the ring frame 432 descends, which can reduce the height of the grabbing manipulator 41 and the power assembly 42, thereby making the grabbing manipulator 41 close to the pallet 2, thereby facilitating the stacking of the container corner fitting 100.

[0065] The implementation principle of the embodiment of the present application is: the conveyor belt 1 inputs the container corner fittings 100 onto the storage plate 321, and under the drive of the pushing drive 322, the container corner fittings 100 rise into the guide pipe 331, and at this time, a number of container corner fittings 100 are stacked in the guide pipe 331 and the stacking channel 342.

[0066] When the transfer mechanism 4 grabs the container corner fitting 100, the grabbing manipulator 41 moves to the top of the stacking channel 342, and a grabbing electromagnet 413 on the grabbing manipulator 41 is arranged opposite to the stacking channel 342. The discharge ring 351 conveys the corresponding container corner fitting 100 upward, and when the top container corner fitting 100 contacts the corresponding grabbing electromagnet 413, the grabbing electromagnet 413 is magnetically fixed to the corresponding container corner fitting 100. Then, under the action of the power component 42, the grabbing manipulator 41 moves, and at this time another grabbing electromagnet 413 is switched to face the stacking channel 342, and then the above steps are repeated. In this way, the multiple grabbing electromagnets 413 on the grabbing manipulator 41 are magnetically fixed to one container corner fitting 100, which enables the grabbing manipulator 41 to transfer multiple container corner fittings 100 each time the container corner fitting 100 is transferred.

[0067] When the transfer mechanism 4 stacks the container corner fittings 100 onto the pallet 2, the power assembly 42 moves the grabbing robot 41 above the pallet 2, and the grabbing electromagnet 413 on the grabbing robot 41 is powered off. At this time, the several container corner fittings 100 on the grabbing robot 41 are all placed on the pallet 2, realizing the stacking of the container corner fittings 100.

[0068] Embodiment 2: An automatic stacking device for container corner fittings, referring to Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that a rotary drive assembly 44 is arranged between the Z-axis drive member 423 and the connecting frame 411, the connecting frame 411 is rotatably connected to the Z-axis drive member 423, the rotary drive assembly 44 is arranged on the Z-axis drive member 423, and the driving end of the rotary drive assembly 44 is connected to the connecting frame 411. In this embodiment, the rotary drive assembly 44 adopts a rotary cylinder or a motor. Under the drive of the rotary drive assembly 44, the mounting plate 412 can be switched from a horizontal state to a vertical state.

[0069] Reference Figure 7 A clearance gap 354 is formed on the side wall of the discharge ring 351 , and the clearance gap 354 penetrates the discharge ring 351 in the vertical direction, and the clearance gap 354 is communicated with the stacking channel 342 .

[0070] Reference Figure 7 and Figure 8 The mounting plate 412 is plugged into and matched with the clearance gap 354 along the vertical direction, and a plurality of grabbing electromagnets 413 on the mounting plate 412 are arranged in sequence at intervals along the vertical direction, and a plurality of grabbing electromagnets 413 are located on the side of the mounting plate 412 facing the stacking channel 342, and the mounting plate 412 is slidably connected to the inner side wall of the clearance gap 354 along the vertical direction.

[0071] When the mounting plate 412 is inserted into the clearance gap 354, the grabbing electromagnet 413 on the mounting plate 412 is located in the clearance gap 354. With the cooperation of the discharge ring 351, the discharge ring 351 can push several container corner fittings 100 to rise, which enables several grabbing electromagnets 413 to magnetically fix a container corner fitting 100 at the same time, which enables the grabbing robot 41 to quickly grab the container corner fitting 100.

[0072] The implementation principle of the embodiment of the present application is as follows: when the transfer mechanism 4 grabs the container corner fittings 100, the rotary drive assembly 44 rotates the mounting plate 412 to a vertical state, and at this time the power assembly 42 inserts the mounting plate 412 into the clearance gap 354. Under the action of the discharge ring 351 and the discharge drive member 352, the discharge ring 351 pushes a number of container corner fittings 100 upward, and the grabbing electromagnets 413 located in the clearance gap 354 are arranged one by one with the container corner fittings 100. At this time, the grabbing electromagnets 413 are all magnetically fixed to the corresponding container corner fittings 100. This enables the grabbing manipulator 41 to grab multiple container corner fittings 100 at a time, thereby increasing the speed at which the grabbing manipulator 41 grabs the container corner fittings 100, and further increasing the stacking speed of the stacking device of the present application.
