Description

Technical Field

[0001] The present invention relates to the technical field of transmission equipment, and in particular to a flexible transmission intelligent connection device. Background Art

[0002] Currently, factories mainly use flexible transmission lines to transport goods. However, the transmission lines are all long and fixed in structure, which is not conducive to warehouse storage and the ability to change the transmission length at any time according to the actual needs of the site. Although there are flexible transmission lines that can be bent, they are usually connected in series using a simple connection method of pins and sleeves. The bending angle has long been limited, and it is impossible to achieve more flexible, changeable and precise angle rotation control between the two sections. In other words, it is impossible to intelligently plan the path to adapt to the actual needs of cargo transportation and arrange it into various "S" shapes to achieve the purpose of truly flexible transmission and cleverly avoid obstacles. As a result, transportation efficiency is reduced and the cost of use is increased. Summary of the Invention

Under the control of a computer, the power device drives the shaft body to rotate, so that a precise angle is formed between the two transmission units, so that the multi-section connected transmission units form various "S"-shaped flexible transmission belts, so as to achieve the purpose of intelligent planning of the "S" shape according to the actual path requirements and flexible control to cleverly avoid obstacles, while improving the transportation efficiency and reducing the use cost of the transmission device.

The scope of protection of this application shall be as defined in the attached claims.

[0035] Reference Figure 1 — Figure 10 One embodiment of the present invention is a flexible transmission intelligent connection device, which is composed of multiple identical transmission units connected end to end in sequence. The transmission unit includes a semicircular rotating tray 7 located at the front and a rectangular transmission part 27 located at the rear. The movable connection part is fixedly connected to the lower end of the semicircular rotating tray 7, and the tail of the rectangular transmission part 27 is fixedly connected to the raised connection part.

[0036] The upper surface of the semicircular rotating tray 7 is mounted with an integrated balance wheel 8, which provides both rotational and steering power. Since the balance wheel is an existing product, its detailed description is omitted. The lower portion of the semicircular rotating tray 7 is fixedly connected to a co-axially positioned semicircular gear 16, which in turn is fixedly connected to the semicircular rotating shaft 5 of the movable connection.

[0037] The movable connection part includes a semicircular rotating shaft 5 and a cavity inside the semicircular rotating shaft. The cavity is divided into a second large cavity 20 and a second small cavity 21. The compression spring B13 is located in the second large cavity 20, and the compression spring B13 is vertically installed, with the upper end fixed on the inner wall of the chamber and the lower end connected to the semicircular wedge B6 located in the second small cavity 21; the front end of the rectangular transmission part 27 extends laterally to form a sleeve 12 that partially extends out of the front end of the semicircular rotating tray 7, and the movable connection part is located in the sleeve 12, wherein the inner circle area of ​​the sleeve 12 is larger than the cross-sectional area of ​​the movable connection part, and the semicircular rotating shaft 5 is provided with a semicircular rotating shaft plane 25 that is located in the center plane of the sleeve 12, and the semicircular wedge B6 in a free state partially extends out of the semicircular rotating shaft plane 25, that is, the semicircular wedge B plane 26 provided on the semicircular wedge B6 forms an angle with the semicircular rotating shaft plane 25.

[0038] The rectangular transmission part 27 includes a main body frame 9, a belt conveyor 10 installed on the main body frame 9, and a square fixed tray 11 for installing the balance wheel integration 8. The main body frame 9 is equidistant from the side length and the diameter of the semicircular rotating tray 7. The balance wheel has its own rotational power and steering power to ensure the accuracy of the balance wheel direction. Since the functions of the balance wheel product have been widely used, they will not be repeated here.

[0039] A swing leg 15 is movably mounted on the side of the main body frame 9. The swing leg 15 swings clockwise by 90° from a horizontal position to play an auxiliary supporting role.

[0040] An electric slide 18 is also installed on the main body frame 9. The electric slide 18 is connected to and drives the rack 17 to perform reciprocating motion. The rack 17 matches the semicircular gear 16 and drives the semicircular gear 16 to rotate forward or reverse.

[0041] The raised connecting portion includes a semicircular fixed shaft 4 and a cavity inside the semicircular fixed shaft 4. The cavity is divided into a first large cavity 19 and a first small cavity 22. The compression spring A14 is located in the first large cavity 19, and the compression spring A14 is installed vertically, with the lower end fixed on the inner wall of the chamber, and the upper end connected to one end of the semicircular wedge A3 located in the first small cavity 22. The semicircular wedge A3 in a free state partially extends out of the semicircular fixed shaft plane 24, that is, the semicircular wedge A plane 23 provided on the semicircular wedge A3 forms an angle with the semicircular fixed shaft plane 24.

[0042] The tail end of the first transmission unit 1 is fixedly connected with a raised connection part, which is matched with the head end of the second transmission unit 2 and provided with a movable connection part containing a sleeve 12, forming a circular shaft body whose outer diameter fits the inner diameter of the sleeve 12. The electric slide 18 drives the rack 17 to reciprocate, and the rack 17 drives the semicircular gear 16 to rotate forward or reverse. The semicircular gear 16 drives the fixed semicircular rotating shaft 5 to rotate, thereby driving the entire circular shaft body pressed together to rotate, driving the first transmission unit 1 to rotate and form an angle with the second transmission unit 2. The angle range is plus or minus 90°. Within this angle range, the computer can intelligently control the precise change of the angle according to the actual path.

[0043] The size and direction of the angle are intelligently controlled by a computer software system (not shown). The specific process is as follows:

[0044] The raised connection part of the first transmission unit 1 is stationary, and the movable connection part of the second transmission unit 2 moves upward from the lower end under the intelligent control of the computer so that the semicircular fixed shaft 4 gradually enters the sleeve 12, and the semicircular fixed shaft plane 24 of the semicircular fixed shaft 4 gradually fits with the semicircular rotating shaft plane 25 of the semicircular rotating shaft 5, and the semicircular wedge A3 contacts the semicircular rotating shaft plane 25. Under the action of the semicircular rotating shaft 5, the semicircular wedge A plane 23 of the semicircular wedge A3 gradually changes from inclined to vertical until it completely coincides with the semicircular rotating shaft plane 25. At this time, the semicircular wedge A3 further compresses the compression spring A14. Under the action of the spring force, the semicircular wedge A plane 23 of the first transmission unit 1 and the semicircular rotating shaft of the second transmission unit 2 are The axis planes 25 fit tightly together. Finally, the semicircular wedge A plane 23 and the semicircular wedge B plane 26 are in the same plane. Under the elastic force of the compression spring A14 and the compression spring B13, the semicircular wedge plane and the semicircular axis body plane are not in the same plane, forming an angle a, 20°≤ɑ≤45°, and the arc-shaped outer walls of the semicircular wedge A and the semicircular wedge B6 fit with the arc-shaped inner wall of the chamber, so that the semicircular rotating axis plane 25 and the semicircular fixed axis plane 24 fit tightly to form a complete circular axis body, which is in a locked connection state, and the outer diameter of the circular axis fits against the inner wall of the sleeve and is precisely limited by the sleeve, effectively preventing the two from moving with each other, thus completing the connection between the first section transmission unit 1 and the second section transmission unit 2.

[0045] When, through the intelligent control of the controller (not shown), the compression spring A14 and the compression spring B13 move so that the planes of the semicircular wedge A and the semicircular wedge B rotate and are in the same plane as the planes of the two semicircular shafts, the semicircular fixed shaft 4 and the semicircular rotating shaft 5 are in a loosened state, and the second section transmission unit 2 descends under the intelligent control of the computer, driving the movable connection part to move downward so that the semicircular fixed shaft 4 gradually detaches from the sleeve 12, thereby realizing the separation of the first section transmission unit 1 and the second section transmission unit 2.

[0046] Preferably, the rectangular transmission portion 27 is further provided with a belt conveyor 10 for conveying goods.

[0047] Preferably, a swing leg 15 is rotatably mounted on the side of the rectangular transmission part 27. The swing leg 15 swings clockwise by 90° from a horizontal position, and plays an auxiliary support role when the transmission unit stops moving to load goods.

[0048] It should be noted that the compression spring and semicircular wedge are in a free state, and the other end of the compression spring is fixed on the inner wall of the chamber, while part of the semicircular wedge extends out of the plane of the shaft body, and the plane of the semicircular wedge forms an angle with the plane of the shaft body. When the two semicircular shaft body planes contact and gradually advance to increase the fitting area, the semicircular wedge gradually changes from inclined to vertical, and the compression spring is gradually compressed. Under the action of the spring force, the two semicircular wedges form a tightly fitting whole, and the plane of the semicircular wedge and the plane of the semicircular shaft body are not in the same plane. The arc-shaped outer walls of the semicircular wedges are in fit with the arc-shaped inner wall of the chamber, so that the two semicircular shaft body planes are tightly attached to form a complete circular shaft body, and the outer diameter of the circular shaft body is in fit with the inner wall of the sleeve and is precisely limited by the sleeve.

[0049] It should be noted that the first section transmission unit and the second section transmission unit are both transmission units with the same structure. The tail end of the transmission unit is fixedly connected with a protruding connection part, and the head end of the transmission unit is provided with a movable connection part placed in the sleeve. When the protruding connection part and the movable connection part are matched and connected in the sleeve, the outer diameter of the circular shaft formed is the same as the nominal size of the inner diameter of the sleeve.

[0050] The above description shows and describes several preferred embodiments of the present application. However, as previously mentioned, it should be understood that the present application is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present application can be used in various other combinations, modifications, and environments and can be modified within the scope of the application concept described herein through the above teachings or technology or knowledge in the relevant field.
