Description

Technical Field

[0001] The present invention belongs to the field of automatic painting lines, and particularly relates to a two-way positioning rotary hanger mechanism for an automatic painting line. Background Art

[0002] In the painting production line, there are various types of hangers, which are generally divided into fixed type and rotary type. The fixed rotary hanger is generally used for hanging workpieces such as flat plates or workpieces with left and right spraying surfaces, and it is difficult to ensure the spraying quality of the front and back surfaces. The rotary hanger can well solve the spraying quality of each surface. However, because the rotary hanger has no positioning device, when the manipulator picks up and places the workpieces to be sprayed, due to the rotation of the rotary hanger, it is easy to collide with the hanging plate for hanging the workpieces to be sprayed, and it is not convenient for loading and unloading.

[0032] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0033] As Figure 1 、 Figure 2 、 Figure 3 shown, a two-way positioning rotary hanger mechanism for an automated painting line includes a rotary hanger, a guiding track 4 for guiding the rotary hanger. The upper end of the rotary hanger is cooperatively installed with a chain conveyor line. A guiding plate 22 is vertically fixed on the outside of the rotary hanger, and a channel corresponding to the width of the guiding plate 22 is provided inside the guiding track.

[0034] As Figure 1 shown, the guiding track 4 includes a guiding member one 41 and a guiding member two 42. The distance between the guiding member one 41 and the guiding member two 42 corresponds to the width of the guiding plate 22, and the guiding plate 22 is an oblong plate;

[0035] One end of both the guiding member one 41 and the guiding member two 42 is turned outward to form an asymmetric inlet. The guiding member one 41 is turned outward to form an arc-shaped plate one 43, and the guiding member two 42 extends outward for a certain distance and then is turned outward to form an arc-shaped plate two 44.

[0036] The arc plate 1-43 and the arc plate 2-44 cooperate with the guide plate 22 to guide the rotary hanger to smoothly enter the guide track 4; the guide plate 22 enters from the side close to the arc plate 1-43, rotates after hitting the arc plate 2-44, and finally the arc at the end of the guide member 1-41 enters between the guide member 1-41 and the guide member 2-42 along the guide track 4, finally positioning the starting position of the hanging member 5 hung at the lower end of the rotary hanger.

[0037] As Figure 1 , Figure 2 , Figure 3 As shown, the rotary hanger includes a rotating shaft 1 and a hanging member 2 sleeved outside the rotating shaft 1. The hanging member 2 is rotatably connected to the rotating shaft 1, and a suspension plate 21 is arranged on the lower side of the hanging member 2;

[0038] The hanging member 2 includes a sleeve 23 sleeved outside the rotating shaft 1. A turntable 24 is coaxially fixed at the lower end of the sleeve 23. The turntable 24 is provided with a circular hole corresponding to the rotating shaft 1, and the diameter of the circular hole corresponds to the diameter of the rotating shaft 1.

[0039] A cylinder 11 is coaxially fixed at the lower end of the rotating shaft 1. The diameter of the cylinder 11 is larger than the diameter of the rotating shaft 1.

The upper part direction of the hanging member 5 corresponding to the suspension plate 21 is perpendicular to the upper part direction of the manipulator. Three suspension plates 21 are arranged in parallel and at equal distances.

[0043] The fact that the upper part direction of the hanging member 5 corresponding to the suspension plate 21 is perpendicular to the upper part direction of the manipulator is to ensure that when multiple rotary hangers are conveyed along the direction of the guide track 4, the upper part direction of the manipulator corresponds to the upper part direction of the suspension plate 21 and is perpendicular to the direction of the guide track 4, reducing the collision interference with other rotary hangers.

[0044] As Figure 1 , Figure 2 , Figure 3 shown, a support rod 25 is fixedly provided on the upper side of the receiving plate 213 on the same side at the lower end of the turntable 24. The support rod 25 is perpendicular to the receiving plate 213. Positioning rods 251 are perpendicularly fixedly provided at both ends of the support rod 25, and the diameter of the positioning rod 251 gradually decreases from bottom to top.

[0045] Four positioning rods are provided on the lower side of the turntable 24. The workpiece to be sprayed includes a cylindrical rod 11 and a ring fixedly provided on the outer side of the upper end of the cylindrical rod 11.

[0047] A cylinder 261 is coaxially provided at the upper end face near the inner ring of the sprocket 26. A dust-proof cover 27 is sleeved on the outer side of the upper end of the cylinder 261. The lower end of the dust-proof cover 27 is open. A through hole is provided on the upper end face of the dust-proof cover 27 corresponding to the rotating shaft 1. A limit retaining ring 28 is provided on the rotating shaft 1 corresponding to the upper end face of the dust-proof cover 27.

[0048] As Figure 1 The chain conveyor line includes a slide rail 3 that is slidably matched with the upper end of the rotating hanger, and a conveyor chain 9 that drives the rotating hanger to move along the direction of the slide rail. The guiding track 4 is parallel to the slide rail 3. A hanging roller 811 is provided at the upper end of the rotating shaft 1, and the hanging roller 811 is in rolling fit with the slide rail 3.

[0049] As Figure 1 shown, a connecting piece 8 is provided after the upper end of the rotating shaft 1 passes through the dust-proof cover 27. The upper end of the rotating shaft 1 is hinged to the connecting piece 8. The upper end of the connecting piece is fixedly connected with a U-shaped steel 81. Hanging rollers 811 are rotatably connected to the inner sides of the two vertical walls of the U-shaped steel 81. The slide rail 3 is an I-shaped steel, and the two hanging rollers 811 on the inner side of the U-shaped steel 81 are respectively arranged corresponding to the grooves on both sides of the slide rail 3.

[0050] As Figure 1As shown, the conveyor chain 9 is arranged on the lower side of the slide rail. The conveyor chain 9 moves along the direction of the slide rail. A plurality of conveying holes 91 are equidistantly arranged on the conveyor chain 9. The upper end of the connecting piece 8 passes through the conveying hole 91 and is fixedly connected to the U-shaped steel 81.

[0051] The conveyor chain drives the movement of the rotating hanger along the direction of the slide rail. When the rotating hanger passes through the guiding track 4, due to the guiding effect of the guiding track 4, the opening direction of the lower side hanger plate of the rotating hanger faces one side, so that it is ensured that the manipulator can accurately hang the hanging part on the hanger plate after grasping it.

[0052] And it can rotate freely 360 degrees where there is no guiding constraint, ensuring the uniformity of powder spraying.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
