Description

Technical Field

[0001] This utility model relates to the field of frame flipping mechanism technology, specifically to a roller conveying mechanism and a frame flipping machine. Background Technology

[0002] In the field of automated logistics and production lines, the conveying and flipping of frame-type materials generally suffers from technical challenges such as low positioning accuracy and low operational efficiency. Traditional conveying mechanisms mostly adopt an open roller design, lacking precise guidance and automatic limit functions, which makes the frames prone to deviation during conveying. In addition, although existing frame flipping equipment has partially achieved automation, it still requires manual intervention and cannot achieve fully automated processing, thus making it difficult to improve work efficiency. Utility Model Content

[0003] In view of this, the present invention provides a roller conveying mechanism and a frame flipping machine to solve the technical problems of traditional conveying mechanisms, which mostly adopt open roller design, lack precise guidance and automatic limit function, causing the frame to easily deviate during the conveying process; in addition, although the existing frame flipping equipment has partially achieved automation, it still requires manual intervention and cannot achieve fully automated processing, thus making it difficult to improve work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Drum motor;

[0007] Several conveying rollers are provided with roller limiting plates on both sides of their inlet end for guiding the frame; the roller motor is used to drive the several conveying rollers to roll.

[0008] The front baffle mechanism and the rear baffle mechanism are spaced apart along the conveying path;

[0009] The first photoelectric sensor, the second photoelectric sensor, and the third photoelectric sensor are arranged sequentially and linked with the front baffle mechanism and the rear baffle mechanism;

[0010] The roller motor drives the frame to move along the route defined by the roller limit plate via the conveying roller.

[0011] Furthermore, the front baffle mechanism includes a fixedly installed front baffle base, on which a front baffle cylinder is disposed. The output end of the front baffle cylinder is connected to the front baffle, and both ends of the front baffle are slidably engaged with the front baffle base through a first optical axis.

[0012] Furthermore, the rear baffle mechanism includes a fixedly installed rear baffle base, on which a rear baffle cylinder is disposed. The output end of the rear baffle cylinder is connected to the rear baffle, and both ends of the rear baffle are slidably engaged with the rear baffle base through a second optical axis.

[0013] Furthermore, the roller limiting plates are symmetrically arranged on both sides of the inlet end of the conveying roller to form a guide channel for the frame. The first photoelectric sensor is linked with the front baffle mechanism, and the second photoelectric sensor and the third photoelectric sensor are linked with the rear baffle mechanism.

[0014] A frame-flipping machine includes a roller conveyor mechanism, and further includes: a frame-flipping bracket, a frame-flipping lifting mechanism, and a rotating mechanism, all mounted on a frame and controlled by an electrical control cabinet. The frame-flipping bracket includes an upper bracket and a lower bracket arranged symmetrically, connected by a bearing sleeve locking plate, and equipped with a drag bar and a limit bar.

[0015] Furthermore, the frame-flipping lifting mechanism includes a pair of lifting components, each including a frame-flipping lifting cylinder, a fourth optical axis, and a slider. The top of the fourth optical axis is provided with an upper bearing and a lower bearing, and the two frame-flipping lifting cylinders are connected by a crossbar.

[0016] Furthermore, the rotating mechanism includes a frame-flipping motor, a rotating frame, and four limiting plates. The rotating frame is connected to the frame-flipping motor via a rotating shaft and is equipped with a fourth photoelectric sensor for detecting the frame position.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0032] refer to Figures 1 to 3 ,like Figure 1, Figure 2 and Figure 3 As shown, this embodiment provides a roller conveyor mechanism 20, which mainly consists of a roller motor 23, several conveying rollers 21, a front baffle mechanism 24, and a rear baffle mechanism 25. The roller motor 23 can drive the several conveying rollers 21 to roll, allowing the frame 100 to move along the several conveying rollers 21. Two roller limiting plates 22 are arranged opposite each other on both sides of the entry end of the conveying rollers 21. Under the restriction and guidance of the two roller limiting plates 22, the frame 100 can travel along a predetermined route. The front baffle mechanism 24 and the rear baffle mechanism 25 are spaced apart. The front baffle mechanism 24 includes: a front baffle base 241, a front baffle cylinder 242, a first optical axis 243, and a front baffle 244. The front baffle base 241 is fixed, the front baffle cylinder 242 is mounted on the front baffle base 241, and the front baffle 244 is rigidly connected to the output end of the front baffle cylinder 242 through a floating joint to ensure synchronous operation. The front baffle 244 is provided with a first optical axis 243 at both ends, and the first optical axis 243 slides with the front baffle base 241. The rear baffle mechanism 25 includes a rear baffle base 251, a rear baffle cylinder 252, and a rear baffle 254. The rear baffle base 251 is fixed, the rear baffle cylinder 252 is mounted on the rear baffle base 251, and the rear baffle 254 is connected to the output end of the rear baffle cylinder 252. A second optical axis 253 is provided at both ends of the rear baffle 254, and the second optical axis 253 slides in cooperation with the rear baffle base 251. Additionally, the conveying mechanism 20 includes a first photoelectric sensor 26, a second photoelectric sensor 27, and a third photoelectric sensor 28 arranged sequentially. The first photoelectric sensor 26 works in conjunction with the front baffle mechanism 24 to control the lifting and lowering of the front baffle 244. The second photoelectric sensor 27 and the third photoelectric sensor 28 work in conjunction with the rear baffle mechanism 25 to control the lifting and lowering of the rear baffle 254.

[0033] Working principle: The roller motor 23 drives the conveyor roller 21 to move forward. When the first photoelectric sensor 26 detects the frame 100, the front baffle cylinder 242 drives the front baffle 244 to descend. Conversely, when the first photoelectric sensor 26 does not detect the frame 100, the front baffle cylinder 242 drives the front baffle 244 to rise. When the second photoelectric sensor 27 and the third photoelectric sensor 28 detect the frame 100, the frame flipping action is performed. After the frame flipping action is completed, the rear baffle cylinder 252 drives the rear baffle 254 to descend. When the third photoelectric sensor 28 does not detect the frame 100, the rear baffle cylinder 252 drives the rear baffle 254 to rise.

[0034] refer to Figures 4 to 7 ,like Figure 4 and Figure 5As shown, this embodiment provides a frame-flipping machine, mainly composed of: a conveying mechanism 20, a frame-flipping bracket 30, a frame-flipping lifting mechanism 40, and a rotating mechanism 50, all mounted on a frame 10. The conveying mechanism 20, the frame-flipping lifting mechanism 40, and the rotating mechanism 50 are all controlled by an electrical control cabinet 11 mounted on the frame 10. The frame-flipping lifting mechanism 40 is located below the rotating mechanism 50, and the rotating mechanism 50 is mounted on the frame-flipping bracket 30. The frame-flipping bracket 30 includes a pair of upper brackets 37, a pair of lower brackets 38, and two pairs of drag bars 34. The brackets 37 and 38 are symmetrically arranged. The upper bracket 37 and the lower bracket 38 on the same side are connected by a bearing sleeve locking plate 311. A bearing sleeve 31 is installed on the bearing sleeve locking plate 311. A bearing sleeve locking plate 36 is installed on both the upper bracket 37 and the lower bracket 38. Two pairs of drag rods 34 are arranged vertically at intervals. The upper pair of drag rods 34 and the lower pair of drag rods 34 are installed at intervals between the corresponding pair of bracket locking plates 33. The bracket locking plates 33 are installed on the corresponding upper bracket 37 / lower bracket 38 through the bearing sleeve locking plates 36. A limit rod 35 is also provided on the bearing sleeve locking plate 36. The upper bracket 37 and the lower bracket 38 are independently driven by the flip-frame cylinders on the corresponding sides.

[0035] like Figure 6 As shown, the frame-flipping lifting mechanism 40 comprises a pair of lifting components and a crossbar 46. The lifting components include a frame-flipping lifting cylinder 43, a fourth optical shaft 44, and a slider 45. The frame-flipping lifting cylinder 43 is pivotally connected to a cylinder seat. The crossbar 46 is connected to the lower end of the pair of frame-flipping lifting cylinders 43. The lower end of the fourth optical shaft 44 is fixed to the crossbar 46.

The top of the fourth optical shaft 44 is provided with an upper bearing 41 and a lower bearing 42 that are spaced apart vertically. The upper bearing 41 is mounted on an upper bearing seat 411, and the lower bearing 42 is mounted on a lower bearing seat 421.

[0036] like Figure 7 As shown, the rotating mechanism 50 includes: a frame-flipping motor 51, a rotating frame 55, and four limiting plates 56. The frame-flipping motor 51 is connected to a rotating shaft 52 via a reducer. The rotating shaft 52 is fixedly connected to the rotating frame 55. A connecting shaft is provided on the side of the rotating frame 55 opposite to the rotating shaft 52. A fourth photoelectric sensor 58 is mounted above the connecting shaft via a photoelectric mounting base 57. Two third optical axes 54 are fixed between the rotating shaft 52 and the connecting shaft. The upper and lower ends of the two third optical axes 54 on the same side are fixed together by an optical axis connecting plate 53. The frame 100 can be placed between the four limiting plates 56.

[0037] Working principle of frame flipping: The upper frame flipping cylinder rises and drives the lower support 38 to rise to the position. Then, the frame flipping motor 51 drives the rotating frame 55 to rotate 180 degrees. The lower frame flipping cylinder descends and drives the upper support 37 to descend to the position. The conveying mechanism 20 then operates to convey the frame.
