Description

Technical Field

[0001] The invention relates to the technical field of automatic packaging of aluminum plates, in particular to automatic packaging equipment for preventing aluminum plates for decoration from being damaged by collision. Background Art

[0002] As a multifunctional decoration material, decorative aluminum plates are widely used in many fields such as construction, transportation, and electronics. Its main function is to beautify the environment and improve the overall quality. Decorative aluminum plates have the advantages of light weight, high strength, corrosion resistance, easy processing and molding, beautiful and durable, and environmentally friendly and recyclable. Through surface treatment processes such as anodizing and painting, decorative aluminum plates can show rich colors and patterns to enhance the decorative effect. At the same time, the recyclability of aluminum also makes it an environmentally friendly material choice.

[0003] Aluminum plates need to be packaged with film before leaving the factory to prevent them from being bumped during transportation. At the same time, aluminum plates may be bumped during the production process. Therefore, they also need to be tested for bumps before leaving the factory. However, at present, most manufacturers use a semi-automatic method with manual cooperation for packaging. This method not only has low production efficiency, but the pre-shipment inspection also depends on the level of the inspectors. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic packaging device for aluminum plates for decoration to prevent them from being damaged by collision, so as to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic packaging device for preventing aluminum plates for decoration from being bumped and damaged, comprising a main bracket and a conveying support assembly, the conveying support assembly is located at the bottom of the main bracket, a first protective packaging device and a second protective packaging device are respectively installed on the main bracket, and a film sticking assembly is installed on the top of the main bracket; the conveying support assembly comprises a conveying bracket, and an electric conveying wheel and a material supporting device are respectively installed on the conveying bracket; the first protective packaging device comprises a first electric telescopic rod, the first electric telescopic rod is installed on the main bracket, a first connecting plate is installed on the output shaft of the first electric telescopic rod, a second electric telescopic rod is installed on the first connecting plate, a first protective shell is installed on the output shaft of the second electric telescopic rod, a first screw rod is rotatably installed on the first protective shell, a symmetrical thread is provided on the first screw rod, a first detection wheel group is slidably installed on the first protective shell, and the first screw rod is threadedly connected to the first detection wheel group.

[0006] The automatic packaging equipment is connected to a control cabinet, and a control system is arranged inside the control cabinet. The control system is used to control the operation of the entire automatic packaging equipment.

[0007] The electric transmission wheel transports the aluminum plate to the automatic packaging equipment, and the supporting device lifts the aluminum plate from the bottom of the aluminum plate and raises the aluminum plate to the height of the first protective packaging device and the second protective packaging device. The control system fine-adjusts the height of the first protective packaging device and the second protective packaging device through the second electric telescopic rod and the sixth electric telescopic rod respectively, so that the first detection wheel group and the second detection wheel group are aligned with the side of the aluminum plate. After that, the control system turns on the first electric telescopic rod, and the output shaft of the first electric telescopic rod extends, driving the first detection wheel group to extend forward until the detection roller fits the side of the aluminum plate. During the process of the detection roller and the aluminum plate fitting, the detection rollers on both sides apply the same pressure to the side of the aluminum plate. Under the joint action of the detection rollers, the two sides of the aluminum plate are displaced and located in the middle of the detection rollers on both sides. After that, the first electric telescopic rod is further extended, so that the spring telescopic rod contracts according to the preset value to fix the two sides of the aluminum plate. The control system synchronously controls the fifth electric telescopic rod to make the second detection wheel group fix the other two sides of the aluminum plate in the same way, thereby achieving the purpose of fixing and correcting the aluminum plate all around, so that the position of the aluminum plate corresponds to the position of the extrusion groove on the extrusion plate.

[0008] The first protective packaging device also includes a first output motor, which is installed on the first protective shell. The output shaft of the first output motor is connected to the first screw rod. A feed tooth belt is rotatably installed on the first protective shell, a transmission tooth is installed on the feed tooth belt, a card joint is installed on the feed tooth belt, a transmission card block is installed on the first detection wheel group, a sliding tooth block is slidably installed on the first protective shell, the feed tooth belt is meshed with the sliding tooth block through the transmission tooth, and a suction head is installed at one end of the sliding tooth block.

[0009] An air pump is arranged in the sliding tooth block, and the air pump is connected to the suction head through a pipeline. The air pump sucks away the air between the suction head and the corner guard through the pipeline, so that the suction head generates suction force to adsorb the corner guard.

[0010] After the first inspection wheel group completes the inspection of the areas near the four corners of the aluminum plate, with further sliding, the transmission block on the inspection slide block is engaged with the card joint, and drives the unloading toothed belt to rotate, and the unloading toothed belt drives the sliding tooth block to slide linearly on the first protective shell through the transmission teeth, and the sliding tooth block drives the suction head forward, and the suction head adsorbs the fitted corner guard and drives the corner guard to extend forward. When the two first inspection wheel groups in the same group have just completed the inspection of the side of the aluminum plate, the two first inspection wheel groups are close and fitted, and the suction head just drives the corner guard to be installed on the four corners of the aluminum plate. Afterwards, the control system closes the suction head to achieve the purpose of simultaneously installing the corner guard while inspecting both sides of the aluminum plate. After the corner guard is installed, the control system controls the first protective packaging device and the second protective packaging device to retract until the first inspection wheel group and the second inspection wheel group are out of contact with the side of the aluminum plate.

[0011] The first protective packaging device also includes a third electric telescopic rod, which is installed on the first protective shell, and a material pusher is installed on the output shaft of the third electric telescopic rod. The first protective shell is filled with a plurality of neatly arranged corner protectors. The corner protectors are used to be installed at the four corners of the aluminum plate to prevent the four corners of the aluminum plate from being bumped.

[0012] The first detection wheel group includes a detection slider, which is slidably installed on the first protective shell, a spring telescopic rod is installed on the detection slider, a transmission block is installed on the detection slider, the detection slider is threadedly connected to the first screw rod, a detection connecting piece is installed on the output shaft of the spring telescopic rod, a detection bracket is rotatably installed on the detection connecting piece, a detection roller is rotatably installed on the detection bracket, a bending rod is installed on the detection bracket, a diaphragm is installed in the detection connecting piece, a piezoelectric element is installed between the diaphragms, one end of the bending rod corresponds to the position of the diaphragm, and a detection spring is installed between the detection bracket and the detection connecting piece.

[0013] A sliding curved groove is arranged on the detection connecting piece, a rotating column is arranged on the detection connecting piece, and a detection bracket is rotatably installed on the detection connecting piece through the rotating column.

[0014] The detection bracket is respectively provided with a wheel hole and a rotating hole, the detection bracket is provided with a rotating measuring rod, the rotating measuring rod is slidably connected with the sliding curved groove, a bending rod is installed on the rotating measuring rod, the detection bracket is rotatably installed on the rotating column through the rotating hole, and the detection bracket is rotatably installed with a detection roller through the wheel hole.

[0015] The control system starts the first output motor, and the output shaft of the first output motor drives the first screw rod to rotate, and the first screw rod drives the detection slider to slide on the first protective shell along the direction of the first screw rod. Since the thread on the first screw rod is symmetrically arranged, when the two detection sliders on the first screw rod slide, they move closer or farther away at the same time. The first screw rod drives the two detection sliders to slide and move closer. The detection slider drives the detection connecting piece to move through the spring telescopic rod, and the detection connecting piece drives the detection roller to slide along the side of the aluminum plate through the detection bracket. When the side of the aluminum plate is uneven due to bumps, the detection roller that contacts the bump will first be bumped along the uneven surface under the pressure of the spring telescopic rod. When the detection roller bumps, it will drive the detection bracket to move. The rotating column deflects, and when the detection bracket deflects, the bending rod is driven to squeeze the diaphragm by rotating the measuring rod. When the diaphragm is compressed, it squeezes the internal piezoelectric element. The piezoelectric element generates an electric charge when it is compressed, and the charge is transmitted to the control system through a wire. When the collision is serious, the detection roller produces a large bump, which drives the detection bracket to deflect at a larger angle, thereby making the piezoelectric element more compressed and generating more electric charge. The control system determines the severity of the collision based on the strength of the electrical signal. During this period, the control system controls the second detection wheel group to perform the same operation, thereby achieving the purpose of collision detection on all sides of the aluminum plate. When the control system detects a collision, it will issue an alarm to the staff, and the staff will repair the aluminum plate after receiving the alarm.

[0016] The film sticking assembly includes an extrusion plate and a packaging connecting rod. The extrusion plate is installed on the main bracket through the packaging connecting rod. An electric slide rail is installed on the packaging connecting rod. A sliding block is slidably installed on the electric slide rail. An electric grabber is installed on the sliding block. A film fixing piece is installed on the packaging connecting rod. A film coil is rotatably installed between the film fixing pieces. An L-shaped pressure rod is installed between the film fixing pieces. An electric pressure wheel is rotatably installed on the bottom end of the L-shaped pressure rod through a connecting piece. A shearing device is provided on the side of the electric pressure wheel close to the extrusion plate. The shearing device is used to cut the film. An extrusion groove is provided at the bottom end of the extrusion plate. The size of the extrusion groove is larger than that of the aluminum plate.

[0017] The control system starts the electric pressure wheel, and the electric pressure wheel rotates, driving the end of the film coil between the electric pressure wheel and the L-shaped pressure rod to extend, and the extended end of the film coil just enters between the upper and lower claws of the electric gripper, and the control system starts the electric gripper, and the upper and lower claws of the electric gripper retract and clamp the end of the film coil, and the control system starts the electric slide rail, and the electric slide rail drives the electric gripper to slide along the electric slide rail to the preset position through the sliding block, and the electric gripper drives the film coil to spread out, and the control system starts the supporting device again, and the supporting device drives the aluminum plate with the corner guard installed to rise to the position of the film laminating component, so that the upper surface of the aluminum plate is fitted with the film coil, and then the control system starts the shearing device, and the shearing device cuts the film, and the control system controls the supporting device to drive the aluminum plate to rise into the extrusion groove, and the extrusion groove makes the film coil fit tightly with the upper surface of the aluminum plate. At the same time, the groove wall of the extrusion groove folds down the film that is longer than the surface size of the aluminum plate, and initially fits with the side of the aluminum plate, and the film wraps the corner guard on the aluminum plate.

[0018] Afterwards, the control system controls the supporting device to drive the aluminum plate to descend to the height of the first protective packaging device, and the control system repeats the previous steps to make the first detection wheel group on the first protective packaging device stick to and press against the side of the aluminum plate again. Afterwards, the control system reversely starts the first output motor, and the first output motor rotates in the opposite direction to drive the two first detection wheel groups in the same group to move away from each other and reset. In this process, the detection roller rolls the side of the aluminum plate. Since the size of the extrusion groove is larger than the aluminum plate, the film on the side of the aluminum plate is not properly extruded and does not fit tightly enough to the side of the aluminum plate. Under the rolling of the detection roller, the film fits tightly against the surface of the aluminum plate. Synchronously, the control system performs the same operation on the second protective packaging device. Afterwards, the control system resets the entire automatic packaging equipment, and the supporting device drives the packaged aluminum plate to move to the electric conveying wheel to complete the unloading, thereby realizing automatic packaging of the aluminum plate.

[0019] The second protective packaging device includes a fifth electric telescopic rod, a second output motor and a second connecting plate. The sixth electric telescopic rod is installed on the output shaft of the fifth electric telescopic rod through the second connecting plate. The second protective shell is installed on the output shaft of the sixth electric telescopic rod. The output shaft of the second output motor passes through the second protective shell and is connected to a second screw rod. The second screw rod is rotatably connected to the second protective shell. A second detection wheel group is slidably installed on the second protective shell. The second screw rod is provided with symmetrical threads. The second detection wheel group is threadedly connected to the second screw rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. Use the first electric telescopic rod and the fifth electric telescopic rod to drive the first detection wheel group and the second detection wheel group to apply pressure on the four sides of the aluminum plate, so that the aluminum plate is centered under uniform pressure, so as to achieve the purpose of fixing and correcting the deviation of the aluminum plate, and make the position of the aluminum plate correspond to the position of the extrusion groove on the extrusion plate.

[0021] 2. Use the first screw to drive the first detection wheel group in the same group to move relative to each other, so that the detection roller rolls along the side of the aluminum plate. When the side of the aluminum plate becomes uneven due to bumps, the first detection wheel group converts the bumps of the bump surface into the bumps of the detection roller, and then converts the bumps of the detection roller into the squeezing of the piezoelectric element in the diaphragm by the bent rod. The piezoelectric element generates an electric charge after being compressed, and the charge is transmitted to the control system through the wire. The control system determines the severity of the bump according to the strength of the electrical signal, thereby achieving the purpose of detecting bumps on the side of the aluminum plate. At the same time, in conjunction with the second detection wheel group, the purpose of detecting bumps all around the aluminum plate is achieved.

[0022] 3. Use the film laminating assembly to realize automatic spreading and shearing of the film coil. Through the support device and the extrusion groove, the film coil is closely attached to the upper surface of the aluminum plate. At the same time, the groove wall of the extrusion groove folds down the film that is longer than the surface size of the aluminum plate and initially fits with the side of the aluminum plate. The film wraps the corner protector on the aluminum plate to achieve the purpose of automatic film laminating.

[0023] 4. While using the first detection wheel group to detect both sides of the aluminum plate, the unloading toothed belt drives the sliding tooth block to move. The sliding tooth block drives the corner guard to move through the suction head to achieve synchronous installation of the corner guard. The corner guard is used to prevent the four corners of the aluminum plate from colliding during transportation.

[0024] 5. By utilizing the slippage of the first detection wheel group and the second detection wheel group when they are reset, the film that is not tightly attached to the side of the aluminum plate is rolled to make the film tightly attached to the surface of the aluminum plate.

[0035] The second protective packaging device 5 includes a fifth electric telescopic rod 51, a second output motor 57 and a second connecting plate 52. A sixth electric telescopic rod 53 is installed on the output shaft of the fifth electric telescopic rod 51 through the second connecting plate 52.

The second screw rod 56 is provided with symmetrical threads. The second detection wheel group 55 is threadedly connected to the second screw rod 56.

[0036] The working principle of the present invention is as follows: the electric conveying wheel 12 transports the aluminum plate to the automatic packaging equipment, the supporting device 13 lifts the aluminum plate from the bottom of the aluminum plate and raises the aluminum plate to the height of the first protective packaging device 4 and the second protective packaging device 5, and the control system fine-adjusts the height of the first protective packaging device 4 and the second protective packaging device 5 through the second electric telescopic rod 43 and the sixth electric telescopic rod 53 respectively, so that the first detection wheel group 45 and the second detection wheel group 55 are aligned with the side of the aluminum plate, and then the control system turns on the first electric telescopic rod 41, and the output shaft of the first electric telescopic rod 41 extends, driving the first detection wheel group 45 to extend forward until the detection roller 453 is fitted with the side of the aluminum plate. During the fitting process of the detection roller 453 and the aluminum plate, the detection rollers 453 on both sides apply the same pressure to the side of the aluminum plate. Under the joint action of the detection rollers 453, the two sides of the aluminum plate are displaced and located in the middle of the detection rollers 453 on both sides. Then, the first electric telescopic rod 41 is further extended to make the spring telescopic rod 452 contract according to the preset value to fix the two sides of the aluminum plate. The control system synchronously controls the fifth electric telescopic rod 51 to make the second detection wheel group 55 fix the other two sides of the aluminum plate in the same way, thereby achieving the purpose of fixing and correcting the aluminum plate all around, so that the position of the aluminum plate corresponds to the position of the extrusion groove on the extrusion plate 31.

[0037] The control system starts the first output motor 47. The output shaft of the first output motor 47 drives the first screw rod 46 to rotate. The first screw rod 46 drives the detection slider 451 to slide on the first protective shell 44 along the direction of the first screw rod 46. Since the thread on the first screw rod 46 is symmetrically arranged, when the two detection sliders 451 on the first screw rod 46 slide, they move closer or farther at the same time. The first screw rod 46 drives the two detection sliders 451 to slide and move closer. The detection slider 451 drives the detection connecting piece 455 to move through the spring telescopic rod 452. The detection connecting piece 455 drives the detection roller 453 to slide along the side of the aluminum plate through the detection bracket 454. When the side of the aluminum plate is uneven due to bumps, the detection roller 453 at the bump is first contacted. Under the pressure of the spring telescopic rod 452, it will bump along with the uneven surface. When the detection roller 453 bumps, it will bring The dynamic detection bracket 454 deflects around the rotating column 4552. When the detection bracket 454 deflects, the bending rod 457 is driven by the rotating measuring rod 4543 to squeeze the diaphragm 456. After the diaphragm 456 is compressed, it squeezes the internal piezoelectric element 459. After the piezoelectric element 459 is compressed, an electric charge is generated, and the charge is transmitted to the control system through a wire. When the collision is serious, the bumps generated by the detection roller 453 are large, which drives the deflection angle of the detection bracket 454 to be larger, so that the piezoelectric element 459 is compressed and squeezed more, and more charges are generated. The control system determines the severity of the collision according to the strength of the electrical signal. During this period, the control system controls the second detection wheel group 55 to perform the same operation, thereby achieving the purpose of collision detection around the aluminum plate. When the control system detects a collision, it will issue an alarm to the staff, and the staff will repair the aluminum plate after receiving the alarm.

[0038] After the first detection wheel group 45 completes the detection of the area near the four corners of the aluminum plate, with further sliding, the transmission block 414 on the detection slider 451 is engaged with the clamping joint 492, and drives the unloading toothed belt 49 to rotate, and the unloading toothed belt 49 drives the sliding tooth block 411 to slide linearly on the first protective shell 44 through the transmission tooth 491, and the sliding tooth block 411 drives the suction head 412 to move forward, and the suction head 412 absorbs the fitted corner protector 410 and drives the corner protector 410 to extend forward. When the two first detection wheel groups 45 of the same group have just completed the detection of the side of the aluminum plate, the two first detection wheel groups 45 are close to and fitted, and the suction head 412 just drives the corner protector 410 to be sleeved on the four corners of the aluminum plate. After that, the control system closes the suction head 412 to achieve the purpose of detecting both sides of the aluminum plate and installing the corner protector 410 simultaneously. After the corner protector 410 is installed, the control system controls the first protective packaging device 4 and the second protective packaging device 5 to retract until the first detection wheel group 45 and the second detection wheel group 55 are out of contact with the side of the aluminum plate.

[0039] The control system starts the electric pressure wheel 37, and the electric pressure wheel 37 rotates, driving the end of the film coil between the electric pressure wheel 37 and the L-shaped pressure rod 36 to extend, and the extended end of the film coil just enters between the upper and lower claws of the electric gripper 35, and the control system starts the electric gripper 35, and the upper and lower claws of the electric gripper 35 are retracted to clamp the end of the film coil, and the control system starts the electric slide rail 33, and the electric slide rail 33 drives the electric gripper 35 to slide to a preset position along the electric slide rail 33 through the sliding block 34, and the electric gripper 35 drives the film coil to be spread out, and the control system starts the electric gripper 35, and the upper and lower claws of the electric gripper 35 are retracted to clamp the end of the film coil. The system starts the supporting device 13 again, and the supporting device 13 drives the aluminum plate with the corner guard 410 installed to rise to the position of the film assembly 3, so that the upper surface of the aluminum plate is fitted with the film coil. Then the control system starts the shearing device, and the shearing device cuts the film. The control system controls the supporting device 13 to drive the aluminum plate to rise into the extrusion groove. The extrusion groove makes the film coil fit tightly with the upper surface of the aluminum plate. At the same time, the groove wall of the extrusion groove folds down the film that is longer than the surface size of the aluminum plate and initially fits with the side of the aluminum plate. The film wraps the corner guard 410 on the aluminum plate.

[0040] Afterwards, the control system controls the supporting device 13 to drive the aluminum plate to descend to the height of the first protective packaging device 4, and the control system repeats the previous steps to make the first detection wheel group 45 on the first protective packaging device 4 again fit and press against the side of the aluminum plate, and then the control system reversely starts the first output motor 47, and the first output motor 47 rotates in the opposite direction to drive the two first detection wheel groups 45 in the same group to move away from each other and reset, during this process, the detection roller 453 rolls the side of the aluminum plate, and since the size of the extrusion groove is larger than the aluminum plate, the film on the side of the aluminum plate is not fully extruded and is not tightly fitted to the side of the aluminum plate, and under the rolling of the detection roller 453, the film is tightly fitted to the surface of the aluminum plate, and synchronously, the control system performs the same operation on the second protective packaging device 5, and then the control system resets the entire automatic packaging equipment, and the supporting device 13 drives the packaged aluminum plate to move to the electric conveying wheel 12 to complete the unloading, thereby realizing the automatic packaging of the aluminum plate.
