For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figures 1 to 9 , Figure 1 The invention discloses an automatic turning and alignment mechanism for a sling. Figure 2What is disclosed is a schematic diagram of the top view of the structure of the sling body 1 when it is not turned over. Figures 3 to 9 What is disclosed is a schematic diagram of a top view of the structure of the sling body 1 in different states when it is flipped. The automatic flipping and alignment mechanism of the sling includes a sling body 1, a displacement driving structure (not shown), a detection structure (not shown), a centripetal force structure 2, a fixed guide structure (not marked) and a movable guide structure 4. The centripetal force structure 2 is arranged on the sling body 1 and generates a centripetal force, which causes the sling body 1 to flip around its center. A flip position 32 is arranged on the guide track between the two ends of the fixed guide structure. When the detection structure detects that the direction of the sling body 1 is forward or reverse, the sling body 1 moves to the flip position 32. When the movable guide structure 4 is located at or away from the flip position 32, the sling body 1 does not flip or flips.

[0028] The hanger body 1 is used to suspend workpieces, such as the inner tank of a water heater, or other types of workpieces, which will not be illustrated here. When it is detected that the direction of the hanger body 1 is reverse, that is, the direction of the workpiece suspended on the hanger body 1 is reverse, the hanger body 1 is automatically flipped so that the direction of the hanger body 1 is forward, and the hanger body 1 with the forward direction is transported out, that is, the workpiece with the forward direction is transported out. It should be noted that when the direction of the suspended workpiece is reverse, the direction of the hanger body 1 is also reverse; when the direction of the suspended workpiece is forward, the direction of the hanger body 1 is also forward.

[0029] In this embodiment, the displacement drive structure may be a transmission chain structure or a transmission belt structure, and at least one of the sling bodies 1 is arranged on the displacement drive structure. When the displacement drive structure is working, the sling body 1 will move accordingly, and the sling body 1 moves along its moving trajectory, which may be a straight line or may not be a straight line, such as a curve, an arc, etc. It should be noted that the displacement drive structure is a prior art, and the present invention does not improve its structure, and the displacement drive structure in the prior art can be directly used, so its structure is not described in detail.

[0030] In this embodiment, the sling body 1 includes a rotating member 11, a suspension rod 12 and a sling 14. The upper end and the lower end of the rotating member 11 are respectively connected to the displacement drive structure and the upper end of the suspension rod 12, and the lower end of the suspension rod 12 is connected to the sling 14. The sling 14 includes two ends (not marked) and a hook 13. The hook 13 is arranged between the two ends. A plurality of perforations (not marked) can be arranged on the two ends. These perforations can be used to assist in fixing the workpiece. The lower end of the suspension rod 12 is connected to the flip center of the sling 14, and the two ends are distributed on both sides of the flip center. It should be noted that the rotating member 11 is a prior art. The present invention does not improve its structure. The rotating member 11 in the prior art can be directly used, so its structure is not described in detail.

[0031] In this embodiment, the centripetal force structure 2 is a guide wheel, and the guide wheel is arranged on one end of the sling body 1. It also includes a connecting piece (not marked), and the connecting piece is arranged on a side surface of one end of the sling body 1, and the guide wheel is arranged on the connecting piece. The centripetal force structure 2 can be replaced by other structures, as long as such structure generates a centripetal force, and the centripetal force causes the sling body 1 to flip, and the structures that meet these requirements are all within the protection scope of the present invention. It should be noted that the sling 14 is centrally symmetrical, and the shapes and weights of the two ends of the sling 14 are the same. However, since the connecting piece is arranged on a side surface of one end of the sling 14, and the guide wheel is arranged on the connecting piece, the shapes of the two ends of the sling 14 are different, and the weights of the two ends of the sling 14 are also different. Therefore, the guide wheel causes the sling 14 to generate a centripetal force, and the centripetal force causes the sling 14 to flip around its center.

[0032] In this embodiment, the detection structure is used to detect whether the direction of the sling body 1 is forward or reverse. The detection structure can detect the direction of the sling 14 by detecting the centripetal force structure 2, or the detection structure can detect the direction of the sling 14 through other structures. The detection structure can use image detection technology or related sensing technology. When the detection structure detects that the image of the sling body 1 is different from the image in the forward direction, it proves that the direction of the sling body 1 is reverse, and the sling body 1 needs to be flipped. When the detection structure detects that the image of the sling body 1 is the same as the image in the forward direction, it proves that the direction of the sling body 1 is forward, and the sling body 1 does not need to be flipped. Alternatively, when the sensor cannot detect the structure of the sling body 1, it proves that the direction of the sling body 1 is reverse, and the sling body 1 needs to be flipped. When the sensor detects the structure of the sling body 1, it proves that the direction of the sling body 1 is forward, and the sling body 1 does not need to be flipped. It should be noted that the detection structure is a prior art, and the present invention does not improve its structure. The detection structure in the prior art can be directly used, so its structure is not described in detail.

[0033] In this embodiment, the fixed guide structure includes a first fixed guide member 31, the flip position 32, and a second fixed guide member 33 which are sequentially arranged according to a guide track. The guide tracks of the first fixed guide member 31 and the second fixed guide member 33 are respectively the same as the moving tracks of the sling body 1, and the first fixed guide member 31 and the second fixed guide member 33 can effectively prevent the sling body 1 from flipping, and the function of the flip position 32 is to flip the sling body 1 by 180 degrees, that is, to flip the sling body 1 which is in the reverse direction to the forward direction.

[0034] The flipping position 32 includes a first flipping member 321 and a second flipping member 322 located on the same side of the moving track of the sling body 1, the first flipping member 321 and the second flipping member 322 form a flipping space, one end of the first flipping member 321 is connected to the first fixed guide member 31, and the other end of the first flipping member 321 is bent and extended in a direction away from the moving track of the sling body 1; one end of the second flipping member 322 is connected to the second fixed guide member 33, and the other end of the second flipping member 322 is bent and extended in a direction away from the moving track of the sling body 1; the other end of the first flipping member 321 and the other end of the second flipping member 322 are arranged opposite to each other. The first flipping member 321 can be curved or arc-shaped; the second flipping member 322 can be curved or arc-shaped.

[0035] In the turning space, the sling 14 turns over 180 degrees, the first turning member 321 forms a first turning track, and the second turning member 322 forms a second turning track. On the first turning track, the sling 14 turns over from zero degrees to ninety degrees; on the second turning track, the sling 14 turns over from ninety degrees to 180 degrees, so that the sling 14 turns over 180 degrees, that is, the sling body 1 with a reverse direction is turned over to a forward direction.

[0036] The other end of the first flip member 321 and the other end of the second flip member 322 are separated by a predetermined distance, that is, the other end of the first flip member 321 and the other end of the second flip member 322 form a flip gap, and the flip gap is preferably located at a position where the sling 14 is flipped 90 degrees. The structures of the other end of the first flip member 321 and the other end of the second flip member 322 can be improved, and the other end of the first flip member 321 and the other end of the second flip member 322 are connected (not shown), and the distance from the connection position to the moving track of the sling body 1 is greater than or equal to the flip radius of the sling 14.

[0037] The flip position 32 may also be improved (not shown), the flip position 32 is a gap, the gap is greater than or equal to the flip radius of the sling body 1, and less than or equal to the flip diameter of the sling body 1. The gap forms a flipping space, in which the sling 14 flips 180 degrees, that is, flips the sling body 1 in the reverse direction to the forward direction.

[0038] In this embodiment, the mobile guide structure 4 includes a driving structure 41 and a mobile guide member 42. The driving end of the driving structure 41 is connected to the mobile guide member 42. The mobile guide member 42 is located at or away from the flip position 32 under the action of the driving structure 41. The first flip member 321 and the second flip member 322 are located on one side of the moving track of the sling body 1, and the mobile guide member 42 is located on the other side of the moving track of the sling body 1. It also includes a rotating seat 43, one end of the mobile guide member 42 is hinged to the rotating seat 43, and the driving end of the driving structure 41 is hinged to the mobile guide member 42.

[0039] When the driving end of the driving structure 41 is extended, the other end of the movable guide 42 rotates around the rotating seat 43, and the movable guide 42 is located on the flip position 32, the movable guide 42 seals the flip position 32, and the movable guide 42 prevents the spreader body 1 from flipping. When the driving end of the driving structure 41 is retracted, the other end of the movable guide 42 rotates around the rotating seat 43, and the movable guide 42 is away from the flip position 32, the movable guide 42 opens the flip position 32, and the spreader body 1 flips on the flip position 32, flipping 180 degrees, that is, flipping the spreader body 1 in the reverse direction to the forward direction.

[0040] The working principle of the present invention is: the displacement driving structure drives the sling body 1 to move along its moving track (see Figures 3 to 9 ), during the movement, the first fixed guide member 31 guides the sling 14 to prevent the sling 14 from turning over. The detection structure detects that the direction of the sling 14 is reverse. When the sling body 1 moves to the turning position 32, the driving end of the driving structure 41 contracts, and the moving guide member 42 moves away from the turning position 32. Under the action of the centripetal force, the sling body 1 turns 180 degrees at the turning position 32, turning the sling body 1 in the reverse direction into the forward direction. Then the sling body 1 moves to the position of the second fixed guide member 33, and the second fixed guide member 33 guides the sling 14 to prevent the sling 14 from rotating, and the displacement drive structure transports the sling body 1 out.

[0041] The detection structure detects that the direction of the spreader 14 is positive (see Figure 2 ), when the sling body 1 moves to the flip position 32, the driving end of the driving structure 41 extends, and the moving guide 42 is located on the flip position 32. The moving guide 42 seals the flip position 32, and the moving guide 42 prevents the sling body 1 from flipping. Then the sling body 1 moves to the position of the second fixed guide 33, and the second fixed guide 33 guides the sling 14 to prevent the sling 14 from rotating, and the displacement driving structure transports the sling body 1 out.

[0042] The present invention adopts the detection structure, the centripetal force structure, the fixed guide structure and the movable guide structure. When the detection structure detects that the direction of the sling body is reverse, the sling body moves to the flipping position, the movable guide structure moves away from the flipping position, and the sling body flips at the flipping position. The present invention has the advantages of low production cost, high work efficiency and low safety hazards.
