Description

Technical Field

[0001] This utility model relates to the field of steel coil gripping and feeding technology, and in particular to a steel coil gripping and feeding system and its gripping equipment. Background Technology

[0002] Steel coils are typically placed vertically or horizontally. The hoisting of steel coils requires the corresponding placement method to achieve better handling results. Vertical placement means that the axis of the steel coil is vertical, while horizontal placement means that the axis of the steel coil is horizontal.

[0003] Currently, the lifting of horizontally placed steel coils mainly uses specialized mechanical lifting equipment, and some companies also use electromagnets for lifting, such as the horizontal steel coil lifting electromagnet disclosed in patent 200720079553.6; the lifting of vertically placed steel coils is mainly done by electromagnets, such as a contactless electrically controlled lifting electromagnet device for vertical steel coils disclosed in patent 201420352662.0.

[0004] Patent 201420352662.0 uses a flat magnetic surface, which is only suitable for steel coils placed vertically; Patent 200720079553.6 uses an arc-shaped magnetic surface plus a flexible magnetic tape to improve adhesion, which is suitable for steel coils placed horizontally. However, for steel coils in the same batch or different batches that use different placement methods, or for steel coils that need to be changed from one placement method to another, it cannot be directly achieved by using only one gripping structure.

[0010] As an optional implementation, the flipping drive device is an electric motor, and the output shaft of the electric motor is a drive end that is connected to the rotating shaft for transmission.

[0011] As another optional implementation, the rotary drive device is a hollow rotary platform.

[0012] As another alternative implementation, the magnetic attraction device uses an electromagnet that is magnetic when de-energized and demagnetized when energized.

[0013] As another alternative implementation, the number of magnetic attraction devices is four, and they are arranged in a cross shape.

[0014] As another optional implementation, the lower frame is also provided with an electromagnet floating device, and each electromagnet is fixed to an electromagnet floating device.

The rotating shaft is also movably connected to the upper frame to be suspended on the upper frame. The upper frame has the ability to rotate in the horizontal direction through the rotating drive device, so that the magnetic suction device installed on the lower frame can have multiple orientations and can pick up steel coils with different placement methods.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] See Figures 1-3 This utility model discloses a steel coil gripping device, including an upper frame 1, a lower frame 2, a rotation drive device 3, and a flipping drive device 4.

[0029] A magnetic attraction device 5 is fixed on the lower frame 2, and the magnetic attraction device 5 is used to magnetically fix the steel coil.

[0030] Rotating shafts 21 extend from both ends of the lower frame 2, and the rotating shafts 21 are movably connected to the upper frame 1; the main body of the flipping drive device 4 is fixed on the upper frame 1, and the drive end of the flipping drive device 4 is connected to the rotating shafts 21 for driving the entire lower frame 2 to flip.

[0031] The drive end of the rotary drive device 3 is fixed to the top of the upper frame 1 and is used to drive the upper frame 1 to rotate in the horizontal direction.

[0032] In this embodiment, the main body of the flipping drive device 4 is fixed to the upper frame 1, the drive end of the flipping drive device 4 is connected to the rotating shaft 21, and the rotating shaft 21 is movably connected to the upper frame 1 (to... Figure 2 For example, the bottom of both ends of the upper frame is provided with a bushing structure, and the rotation shaft of the lower frame is movably connected to the bushing structure, so that the lower frame can be hung on the upper frame 1. In this way, the lower frame 2 can be driven by the flipping drive device 4 to achieve flipping.

[0033] The lower frame 2 of this utility model is provided with a rotating shaft 21, which is connected to the flipping drive device 4 through the rotating shaft 21 and has the ability to flip up and down. The rotating shaft 21 is also movably connected to the upper frame 1 to be suspended on the upper frame 1. The upper frame 1 has the ability to rotate in the horizontal direction through the rotating drive device 3, so that the magnetic suction device 5 installed on the lower frame 2 can have multiple orientations to adapt to the suction of steel coils with different placement methods. In addition, after suctioning a steel coil with one placement method, the orientation of the steel coil can be changed by the flipping drive device 4 and the rotating drive device 3 if there is enough space, such as changing from vertical placement to horizontal placement or from horizontal placement to vertical placement.

[0034] In an optional embodiment, the flipping drive device 4 is an electric motor, the output shaft of which is connected to the rotating shaft 21 via a drive end; preferably, a reduction mechanism is provided between the electric motor and the rotating shaft 21. The electric motor can be a hardened gear reducer, such as a KAZ87 model.

[0035] In another optional embodiment, the rotary drive device 3 is a hollow rotary platform, and the model of the hollow rotary platform may be AF142.

[0036] In another optional embodiment, the magnetic attraction device 5 is an electromagnet that is magnetic when the power is off and demagnetized when the power is on; in this way, the steel coil can be guaranteed not to fall after a sudden power outage, and can be lowered only when the power is on, which can greatly ensure safety.

[0037] In another optional embodiment, the number of magnetic suction devices 5 is four, arranged in a cross shape. A clearance space is provided between the four magnetic suction devices 5 for the central shaft of the steel coil unloading mechanism to pass through.

[0038] In another optional embodiment, the lower frame 2 is further provided with an electromagnet floating device 6, and each electromagnet 5 is fixed to an electromagnet floating device 6; the electromagnet floating device 6 includes a sliding rod 61, a spring 62 and a base 63; the base 63 is provided with a channel 631 for the sliding rod 61 to slide, and the entrance of the channel 631 is located on the surface of the base 63; one end of the sliding rod 61 is fixed to the bottom surface of the electromagnet 5, and the other end of the sliding rod 61 is provided with a limiting part 611, which is limited and cooperates with the exit of the channel 631; the spring 62 is sleeved on the sliding rod 61, and both ends of the spring 62 abut against the surface of the base 63 and the bottom surface of the electromagnet 5, respectively.

[0039] In this embodiment, the electromagnet floating device 6 can improve the adhesion between the electromagnet and the surface of the steel coil, avoiding the situation where multiple electromagnets cannot fully adhere to the steel coil at the same time if the steel coil is not laid flat.

[0040] In another optional embodiment, a plurality of slidable limiting members 7 are also included; the limiting members 7 are disposed on the lower frame 2 and are used to abut against the steel coil to restrict its movement, thereby improving the stability and reliability of the gripping device during movement.

[0041] In another optional embodiment, a cylinder 8 is further included for driving the movement of the limiting member 7, the piston rod of the cylinder 8 having its rod head fixed to the limiting member 7; a guide rail 9 is provided on the lower frame 2, and the limiting member 7 is slidably connected to the guide rail 9. In use, the center point of the limiting members 7 (at least three) in the attached drawings can be determined first. The limiting members 7 in the attached drawings move towards this center point, so that the center of the circle determined by the positions of all the limiting members 7 coincides with this center point. Since the steel coil is cylindrical and basically symmetrical about its axis, the axis of the steel coil can intersect with this center point, thus achieving the positioning of the steel coil's axis. This facilitates the subsequent mounting of the steel coil onto fixed posts at various angles, requiring only a corresponding adjustment of the angle of the steel coil's axis.

[0042] In another optional embodiment, a protective cover 10 is also included, which is disposed on the lower frame 2 and is used for dust protection.

[0043] For example, to transport a vertically placed steel coil (i.e., the axis of the steel coil is vertical) from position one to the horizontal workpiece processing axis at position two, the steel coil needs to be picked up and then converted to a horizontal placement orientation: the lower frame 2 rotates to the horizontal direction, the magnetic suction device 5 picks up the steel coil, and the limiting part 7 slides to abut and fix the steel coil. Then, the lower frame 2 rotates 90 degrees to make the axis of the steel coil horizontal. After reaching position two, the axis of the steel coil is adjusted to face the workpiece processing axis at position two by the rotation drive device 3, so that it can be easily sent to the workpiece processing axis.

[0044] Example 2

[0045] This utility model discloses a steel coil gripping and feeding system, including a crane and the gripping device described in Embodiment 1. The main body of the rotation drive device of the gripping device is connected to the crane. The crane is used to move the gripping device to the feeding position in both horizontal and vertical directions. The gripping device is used to grip the steel coil and adjust the axial orientation of the steel coil to the feeding direction. Through the crane, the gripping device can be moved, and after being lifted, there is sufficient space to flip the frame. Simultaneously, the gripping device can adjust the axial orientation of the steel coil for convenient feeding.
