Description

Technical Field

[0001] The invention relates to the technical field of cargo depalletizing, and in particular to a depalletizing suction cup for a container trailer in an intelligent quick-loading system. Background Art

[0002] With the progress of society and the development of science and technology, automation equipment has been widely used. Automatic depalletizing robots are mainly a type of robots used for depalletizing. They are usually composed of a structure for transporting drag boxes and a structure for absorbing drag boxes. The structure for absorbing drag boxes usually uses a suction cup to complete the absorption of the drag boxes.

[0003] In order to improve the suction effect on the tow box, the automatic depalletizing robot in the existing quick-loading system generally adopts a sponge suction cup. The sponge suction cup is generally composed of a vacuum generator, a muffler, an electromagnetic valve and a sponge installed at the bottom of the shell. When it works, it needs to be equipped with compressed gas, because compressed gas is very convenient and economical. The compressed gas is introduced into the vacuum generator through the air source delivery pipeline to generate a vacuum, which can make the sponge suction cup form suction and fixation on both sides of the tow box. Since compressed gas is used as the air source, it is a high-pressure gas, which has a great impact on the air source delivery pipeline and various parts. There are very high requirements for the connection sealing of parts. In actual applications, air leakage problems often occur due to incorrect installation and connection methods, loose bolts at the connection, aging of equipment and other problems, resulting in gas leakage in the gas source transmission pipeline, and the compressed gas pressure and flow rate both decrease, which makes the vacuum degree of the sponge suction cup decrease, and the tow box cannot be adsorbed and fixed. The tow box will move downward in a free fall due to its own gravity, and the items in the tow box will be damaged, and even worse, a safety accident will occur. Therefore, the present application provides a tow box destacking suction cup for an intelligent quick-installation system to meet the needs. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0035] refer to Figure 1-6The suction cup for destacking boxes in an intelligent quick-loading system shown in the figure includes a mounting top frame 2 and a suction cup mounting frame 1 mounted at the lower end of the mounting top frame 2, and a sponge suction cup 5 is mounted on the suction cup mounting frame 1, and a lifting cylinder 3 is fixedly connected to the upper end of the mounting top frame 2, and the output end of the lifting cylinder 3 penetrates the mounting top frame 2 and is fixedly connected to the suction cup mounting frame 1, and a plurality of guide rods 6 that penetrate the mounting top frame 2 are fixedly connected to the upper end of the suction cup mounting frame 1, and also includes an anti-fall unit 7 for preventing the box from falling and a motion sensor 9 installed at the side end of the suction cup mounting frame 1, the motion sensor 9 is used to detect whether the clamped and adsorbed box moves downward, the anti-fall unit 7 and the motion sensor 9 are both connected to the computer control end, and the anti-fall unit 7 includes a telescopic rod fixed to the lower end of the suction cup mounting frame 1 72, a buffer spring 711 is sleeved on the outer periphery of the telescopic rod 72, a magnetic field shielding box 71 is fixedly connected to the lower end of the telescopic rod 72, an L-shaped support plate 73 is slidably provided in the inner cavity of the magnetic field shielding box 71, and the L-shaped support plate 73 includes a magnetic isolation vertical plate and a support horizontal plate, a ball 710 is provided at the bottom of the support horizontal plate, a plurality of repulsive electromagnets 76 are provided on the side ends of the L-shaped support plate 73 and the inner wall of the magnetic field shielding box 71, the opposite end magnetic poles of the plurality of repulsive electromagnets 76 on both sides are the same, and the two adjacent repulsive electromagnets 76 on the same side are separated by a magnetic isolation plate 77, and the plurality of repulsive electromagnets 76 on the same side are covered in a magnetic field shielding frame 74, and a magnetic field shielding frame 74 is provided with a magnetic opening corresponding to the repulsive electromagnet 76 78, also includes a reset component for resetting the L-shaped support plate 73. The mounting top frame 2 of the destacking suction cup is installed on the screw mechanism of the transportation system and is moved by a servo motor. The destacking suction cup is used in combination with two groups when in use, and two sponge suction cups 5 are used to adsorb and fix the two side ends of the tow box. For the upper tow boxes stacked together, the L-shaped support plate 73 is moved to the bottom of the upper tow boxes and then the sponge suction cups 5 are used for adsorption and transportation. For the tow boxes on the bottom layer, when the sponge suction cups 5 are driven to move upward by the lifting cylinder 3, the lower end of the magnetic field shielding box 71 will first form a conflict with the ground or support plate used to support the tow boxes, and squeeze the buffer spring 711. When the sponge suction cups 5 move to the adsorption position, they adsorb the tow boxes and make the tow boxes After being lifted off the ground, the buffer spring 711 is reset so that the L-shaped support plate 73 is located below the tow box. During the tow box transfer process, when the motion sensor 9 detects that there is a problem with the compressed gas supply pipeline (including the main air supply pipeline and the branch air supply pipeline) of the sponge suction cup 5, which makes it impossible to adsorb the tow box and causes the tow box to move downward, the computer control end will control the electromagnet 76 to be energized, and the L-shaped support plate 73 will move outward quickly based on the principle of like charges repel each other, so that the horizontal plate of the L-shaped support plate 73 catches the downward moving tow box and forms support for the bottom of the tow box, which can prevent the tow box from falling and form anti-fall protection for the tow box. The L-shaped support plate 73 is driven by magnetic force and has a fast reaction speed, so that the L-shaped support plate 73 can move quickly in a short time.

[0036] It should be noted that: first, the L-shaped support plate is installed below the sponge suction cup 5; second, considering that the cylinder uses compressed gas when in use, in order to save costs and facilitate maintenance, the compressed gas of the general factory is generally the same gas source as the compressed gas of the sponge suction cup 5. When there is a leak in the main air supply pipeline of the air source, it will affect the suction force of the sponge suction cup 5 and also affect the normal movement of the cylinder. The cylinder has high requirements for the air tightness of the pipeline connection, which is easy to cause air leakage and thus affect the operation of the cylinder. Therefore, it is not considered to use the cylinder as the power source for the movement of the L-shaped support plate 73; third, after the sponge suction cup 5 adsorbs the tow box, its motion sensor 9 should be opposite to the side end of the tow box, and the movement The height of the sensor 9 is lower than the height of the tow box so that the motion sensor 9 can detect the movement of the tow box; fourth, the magnetic field shielding frame 74 protects the internal electromagnet to prevent collision with the electromagnet at the opposite end during resetting, which may cause damage to the electromagnet; fifth, the arrangement of the magnetic field shielding frame 74 and the magnetic isolation vertical plate can ensure that the magnetic field of the internal electromagnet does not cause magnetic field influence on external equipment; sixth, the arrangement of the magnetic field shielding frame 74 and the magnetic isolation plate 77 ensures that the electromagnets on the same side are independent of each other and are not affected by each other's magnetic fields during operation, so that the L-shaped support plate 73 is only subjected to the magnetic force consistent with its movement direction, which is beneficial to the instantaneous rapid movement of the L-shaped support plate 73.

[0037] As a preferred implementation in this embodiment, Figure 3 As shown, the reset component is a reset spring 75, and the reset spring 75 is fixedly connected between the magnetic field shielding box 71 and the L-shaped support plate 73. The repulsion electromagnet 76 can be powered off by controlling the computer control end. At this time, the L-shaped support plate 73 moves back to the magnetic field shielding box 71 through the elastic force of the reset spring 75.

[0038] As a preferred implementation method in this embodiment, elastic buffer pads 79 are fixed on the impact end surface of the L-shaped support plate 73 and the end surfaces of the opposite ends of the two magnetic field shielding frames 74. Since the magnetic force is used to drive the L-shaped support plate 73 to move rapidly, it will form a violent collision with the inner wall of the magnetic field shielding and generate collision noise. Therefore, elastic buffer pads 79 are provided to buffer the collision and reduce noise.

[0039] As a preferred implementation in this embodiment, Figure 7As shown, it also includes a limiting unit 8 for preventing the L-shaped support plate 73 from rebounding and causing a secondary impact. The limiting unit 8 includes a magnetic field shielding tube 81 that is sealed and passes through the magnetic field shielding box 71. A limiting electromagnet 83 is installed in the magnetic field shielding tube 81. A mounting ring 85 is fixed to the right end of the limiting electromagnet 83, and the mounting ring 85 is fixedly connected to a sliding limiting block 82 through a lifting spring 84, and the outer end of the limiting block 82 slides against the side end of the horizontal plate, and the limiting electromagnet 83 is electrically connected to the computer control end. This is to prevent the vertical plate of the L-shaped support plate 73 from rebounding after colliding with the magnetic field shielding box 71 and colliding with the magnetic field shielding box 71 again under the action of magnetic force, that is, to avoid the L-shaped support plate 73 from rebounding. And a secondary collision is generated, so a limit unit 8 is set. When the vertical plate of the L-shaped support plate 73 collides with the magnetic field shielding box 71 for the first time, the vertical plate of the L-shaped support plate 73 just leaks out the blocked limit block 82. At this time, the limit block 82 is pushed out by the elastic force of the lifting spring 84, and the side end of the limit block 82 will contact the side end of the L-shaped support plate 73 to form a limit to prevent the L-shaped support plate 73 from rebounding and generating a secondary collision. The limit electromagnet 83 can be energized by the computer control end, so that the metal limit block 82 can move toward the magnetic field shielding tube 81, thereby releasing the obstruction to the L-shaped support plate 73. At this time, the L-shaped support plate 73 is reset by the elastic force of the reset spring 75.

[0040] As a preferred implementation in this embodiment, Figure 7 As shown, sound absorbing panels 10 are provided on the top and bottom of the inner cavity of the magnetic field shielding box 71, and the sound absorbing panels 10 are used to reduce collision noise.

[0041] As a preferred implementation in this embodiment, Figure 7 As shown, a vacuum chamber 11 is provided in the magnetic field shielding box 71, and a plurality of structural support columns 12 are installed in the vacuum chamber 11. The vacuum chamber 11 can isolate noise from propagating outward, which is helpful to reduce noise.

[0042] As a preferred implementation mode in this embodiment, an alarm connected to the computer control terminal is also provided, which is not shown in the figure. Two alarms are provided, one alarm is installed in the monitoring room, and the other alarm is fixedly installed on the suction cup mounting frame 1, which is used to alarm and remind the staff.

[0043] As a preferred implementation in this embodiment, Figure 1 As shown, the suction cup mounting frame 1 is movably connected to the sponge suction cup 5 through a plurality of universal ball hinges 4 fixedly connected to the side ends thereof. When sucking on the tow boxes placed in different directions, the sponge suction cup 5 can be driven to adjust the angle through the rotation of the universal ball hinge 4, so that the tow boxes placed in different directions are subjected to more uniform force.

[0044] As a preferred implementation in this embodiment, Figure 3 As shown, a plurality of shock-absorbing holes 13 are provided on the supporting transverse plate, which can reduce the vibration caused by the collision of the L-shaped supporting plate 73, thereby reducing the noise caused by the vibration and collision. Example

[0045] refer to Figure 8 and Fig. 9 , which is different from the first embodiment, is that the reset component includes a first attraction magnetic group 14 and a second attraction magnetic group 15 composed of a plurality of attraction electromagnets, the first attraction magnetic group 14 is mounted on the L-shaped support plate 73, and the second attraction magnetic group 15 is mounted on the magnetic field shielding box 71, and the magnetic poles of the attraction electromagnets at the opposite ends of the first attraction magnetic group 14 and the second attraction magnetic group 15 are opposite, and the repulsion electromagnet 76 can be controlled to be powered off, and after the limit block 82 blocks the L-shaped support plate 73, the plurality of attraction electromagnets at the two opposite ends can be controlled to be powered on at the same time, so that the L-shaped support plate 73 moves into the magnetic field shielding box 71.

[0046] In Example 1, a reset spring 75 is used for reset. Its disadvantage is that when the L-shaped support plate 73 is driven by magnetic force, the reset spring 75 has a pulling force on the L-shaped support plate 73 when extending, which is opposite to the movement direction of the L-shaped support plate 73, and the pulling force becomes larger and larger, which reduces the movement speed of the L-shaped support plate 73, so that the reaction speed of the anti-fall unit 7 decreases. At that time, due to the reduction in the movement speed of the L-shaped support plate 73, the degree of collision between it and the magnetic field sheet shielding box 71 is reduced, which is beneficial to reducing noise; in Example 2, it uses the first attraction magnetic group 14 and the second attraction magnetic group 15 as the reset parts of the L-shaped support plate 73, which will not hinder the movement of the L-shaped support plate 73, and can make the L-shaped support plate 73 move quickly under the action of the magnetic field of the repulsive electromagnet 76, but its cost is more expensive than the reset spring 75 in the embodiment, and the collision is fierce, generating a large noise, and it can be selected according to actual production needs.

[0047] It should be noted that: 1. The attraction electromagnet 76 and the repulsion electromagnet 76 of the first attraction magnetic group 14 and the second attraction magnetic group 15 are spaced apart and separated by a magnetic isolation plate 77, and the first attraction magnetic group 14 and the second attraction magnetic group 15 are both located in the corresponding magnetic field shielding frame 74; 2. The magnetic attraction force generated between the first attraction magnetic group 14 and the second attraction magnetic group 15 is smaller than the repulsion electromagnet generated between the opposite sides, thereby reducing the collision effect between the two magnetic field shielding frames 74.

[0048] Working principle of the utility model: the destacking suction cup is used in two groups, and two sponge suction cups 5 are used to absorb and fix the two side ends of the tow box. For the upper tow boxes stacked together, the L-shaped support plate 73 is moved to the bottom of the upper tow box and then the sponge suction cup 5 is used for absorption and transportation. For the tow boxes on the bottom layer, when the sponge suction cup 5 is driven to move upward by the lifting cylinder 3, the lower end of the magnetic field shielding box 71 will first form a conflict with the ground or support plate used to support the tow box, and squeeze the buffer spring 711. When the sponge suction cup 5 moves to the absorption position, it absorbs the tow box and lifts the tow box off the ground, and the buffer spring 711 is reset to make the L-shaped support plate 73 in the position Under the tow box, during the tow box transfer process, when the motion sensor 9 detects that there is a problem with the compressed gas air supply pipeline (including the main air supply pipeline and the branch air supply pipeline) of the sponge suction cup 5, which makes it impossible to adsorb the tow box and causes the tow box to move downward, the computer control end will control the electromagnet 76 to be energized, and the L-shaped support plate 73 will move outward quickly based on the principle of like charges repelling each other, so that the horizontal plate of the L-shaped support plate 73 catches the tow box moving downward and supports the bottom of the tow box, which can prevent the tow box from falling and form an anti-fall protection for the tow box. The magnetic force is used to drive the L-shaped support plate 73, and its reaction speed is fast, so that the L-shaped support plate 73 can move quickly in a short time.

[0049] The reset component 73 is also included for resetting the L-shaped support plate 73. The reset component can be a reset spring 75 or a first attraction magnetic group 14 and a second attraction magnetic group 15. The reset spring 75 is cheap, reduces the degree of collision, and reduces noise. The first attraction magnetic group 14 and the second attraction magnetic group 15 are used, which is conducive to the rapid extension movement of the L-shaped support plate 73, thereby improving the anti-falling effect of the anti-falling unit 7. It can be selected according to actual needs.

[0050] It also includes a limiting unit 8 for preventing the L-shaped support plate 73 from rebounding and causing a secondary collision. When the vertical plate of the L-shaped support plate 73 collides with the magnetic field shielding box 71 for the first time, the vertical plate of the L-shaped support plate 73 just leaks out the blocked limiting block 82. At this time, the limiting block 82 is pushed out by the elastic force of the lifting spring 84, and the side end of the limiting block 82 will contact the side end of the L-shaped support plate 73 to form a limit to prevent the L-shaped support plate 73 from rebounding and causing a secondary collision.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
