Description

Technical Field

[0001] The utility model generally relates to the technical field of high-altitude transportation, and more specifically relates to an aerial suspension conveyor line. Background Art

[0002] An overhead conveyor line, also known as a suspended conveyor line or overhead conveyor, is a device that continuously transports materials through space. Typically driven by a motor, an overhead conveyor line operates a trolley, hanger, and other components on an overhead track, completing the material transport process. It offers technical advantages such as high flexibility, a small footprint, a high load capacity, ease of maintenance, and high safety.

[0003] Most existing overhead conveyors are friction rod type, which utilizes a rotating friction rod to rub against the trolley's wheels to drive the trolley's movement. This type of system is typically used for cargo weighing over 150kg. For cargo weighing less than 150kg, the friction rod type results in significant resource waste, and belt type systems are generally preferred. Belt-type overhead conveyors require the trolley to switch tracks or turn to ensure operational flexibility. Existing overhead conveyors experience limited smooth trolley movement during these track changes or turns.

[0004] Therefore, it is necessary to provide an aerial suspension conveyor line to at least partially solve the above problems. Utility Model Content

[0062] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with embodiments of the present invention.

[0063] In order to fully understand the embodiments of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0064] The utility model provides an aerial suspension conveyor line.

[0065] See also Figures 1 to 5 The aerial suspension conveyor line 1 includes a first track 11 and a second track 12. The first track 11 is arranged along a first horizontal direction D1, and the second track 12 is arranged along a second horizontal direction D2, and the second horizontal direction D2 is inclined or perpendicular to the first horizontal direction D1. Furthermore, the aerial suspension conveyor line 1 also includes a traveling trolley 20 and a track-changing component 13. Specifically, the traveling trolley 20 is configured to be able to move between the first track 11 and the second track 12. The traveling trolley 20 includes a first wheel group 21 and a second wheel group 22, and the first wheel group 21 and the second wheel group 22 both have a pressing component 24 (see Figure 5 The track-changing member 13 is connected to the first track 11 and the second track 12 . The track-changing member 13 has an arc-shaped accommodating cavity 13 a , and the accommodating cavity 13 a is used for the traveling trolley 20 to pass through.

[0066] It should be noted that the overhead suspension conveyor line 1 further includes a drive assembly 30, which includes a transmission belt 31 configured in a closed shape (see FIG. Figure 5 ). The transmission belt 31 is located inside the first track 11 and the second track 12, and the driving assembly 30 is used to drive the traveling trolley 20 to move. Among them, the pressing member 24 is movable between a first position and a second position along the vertical direction DH. The pressing member 24 located at the first position abuts against the transmission belt 31 to move with the transmission belt 31, and the pressing member 24 located at the second position is disengaged from the transmission belt 31. When one of the first wheel group 21 and the second wheel group 22 is located in the accommodating cavity 13a, the other of the first wheel group 21 and the second wheel group 22 is located inside the first track 11 or the second track 12. In addition, the pressing member 24 at the other of the aforementioned is located in the first position to drive the traveling trolley 20 to pass through the accommodating cavity 13a.

[0067] According to the aerial suspension conveyor line 1 of the present invention, when the traveling trolley 20 switches tracks, the clamping member 24 at the first wheel group 21 or the second wheel group 22 can cooperate with the transmission belt 31, thereby ensuring that the traveling trolley 20 can pass through the accommodating cavity 13a of the track changing member 13, thereby improving the flexibility of the operation of the aerial suspension conveyor line 1.

[0068] Those skilled in the art will appreciate that the drive assembly 30 also includes a power component 32 and a driven component 33. For a single transmission belt 31, for example, located within the aforementioned first track 11, the driven components 33 are arranged in pairs, with adjacent driven components 33 spaced apart along the first horizontal direction D1 (i.e., the orientation of the first track). At least one driven component 33 is drivingly connected to the power component 32, which can be a motor. The power component 32 is mounted to one side of the first track 11.

[0069] The following describes how the traveling trolley 20 switches tracks or turns.

[0070] See also Figure 1 and Figure 2 The first wheel set 21 and the second wheel set 22 are both located outside the accommodating cavity 13a. The track-changing component 13 is roughly in the shape of a quarter arc and has an accommodating cavity 13a opening downward. Figure 3 and Figure 4 One of the first wheel set 21 and the second wheel set 22 is located in the accommodating cavity 13a, and the other is located inside the first track 11 and the second track 12. Figure 4 In the embodiment, the first wheel group 21 is located in the accommodating cavity 13a, and the second wheel group 22 is located inside the first track 11. It can be understood that the traveling trolley 20 also includes a crossbeam 23, which is arranged in the horizontal direction, and the first wheel group 21 and the second wheel group 22 are pivotally connected to the crossbeam 23 around the vertical direction DH. The aerial suspension conveyor line 1 also includes a hanger 40, which is located below the crossbeam 23 and connected to the crossbeam 23, and the hanger 40 is used to carry goods. It can be understood that since the present application describes a belt-type aerial suspension conveyor line, the weight of the goods carried by the hanger 40 generally does not exceed 150 kg.

[0071] Please continue reading Figure 3 and Figure 4 When the first wheel set 21 enters the accommodating cavity 13a, since the accommodating cavity 13a has no power source, in other words, the first wheel set 21 loses power after entering the accommodating cavity 13a. However, the second wheel set 22 is still in contact with the transmission belt 31 inside the first track 11, so that the second wheel set 22 pulls or pushes the first wheel set 21 to move in the accommodating cavity 13a until it completely passes through the accommodating cavity 13a. During this process, the movement of the trolley 20 will not be interfered with or affected by other components, ensuring smooth movement. The track-changing component 13 only provides guidance for the trolley 20 to change direction and will not affect the movement of the trolley 20. Figure 4 In the embodiment, if the second wheel set 22 pulls the first wheel set 21 to move, after the first wheel set 21 completely passes through the accommodating cavity 13a, the first wheel set 21 will contact the transmission belt 31 in the first track 11, thereby regaining power. If the second wheel set 22 pushes the first wheel set 21 to move, the first wheel set 21 will enter the second track 12 after passing through the accommodating cavity 13a, thereby regaining power (see Figure 2 After that, the second wheel set 22 enters the accommodating cavity 13a and loses power. The first wheel set 21 pulls the second wheel set 22 through the accommodating cavity 13a, so that the second wheel set 22 enters the second track 12 and contacts the transmission belt 31 inside the second track 12 to obtain power.

[0072] See also Figure 5 The pressing member 24 has a travel direction along the traveling trolley 20 (see Figure 5 The first end 24a and the second end 24b are adjacent to each other (indicated by the arrow in the middle). The first end 24a is located in front of the second end 24b, and the clamping member 24 also has a guide surface 24c located at the first end 24a. It should be noted that, when the trolley 20 is completely located at the first track 11, the guide surface 24c is inclined relative to the first horizontal direction D1 and the vertical direction DH, and the guide surface 24c is connected to the top surface of the clamping member 24. When the moving path of the trolley 20 is confirmed, by setting the orientation of the guide surface 24c, when the trolley 20 moves from the accommodating cavity 13a to the inside of the first track 11 or the second track 12, the guide surface 24c preferentially contacts the transmission belt 31, so that the process of the trolley 20 obtaining power is smoother.

[0073] Furthermore, the first wheel assembly 21 and the second wheel assembly 22 each further include a bracket 25, a first connecting member 26 and a first elastic member 27. Figure 5 The second wheel assembly 22 is shown. Specifically, a first connecting member 26 is disposed along the vertical direction DH and is movably connected to the bracket 25 along the vertical direction DH. The pressing member 24 is detachably connected to the first connecting member 26 to facilitate assembly and maintenance. A first elastic member 27 is sleeved around the outer periphery of the first connecting member 26 and is located between the bracket 25 and the pressing member 24. The first elastic member 27 is used to drive the pressing member 24 from the second position to the first position. It will be appreciated that the first elastic member 27 can be configured as a spring.

[0074] See also Figure 2 and Figure 4 The track-changing member 13 has a first connecting end 131 and a second connecting end 132. The first connecting end 131 is connected to the first track 11, and the second connecting end 132 is connected to the second track 12. Figure 6 Alternatively, the first rails 11 are arranged in pairs, with adjacent first rails 11 spaced apart along the first horizontal direction D1. In other words, the number of first connecting ends 1131 of a single track-changing member 113 is two and they are respectively connected to adjacent first rails 11 along the first horizontal direction D1.

[0075] See also Figure 6 and Figure 7Furthermore, the overhead suspended conveyor line 2 also includes a guide member 14, which is pivotally connected to the track-changing member 13 around the vertical direction DH. The guide member 14 is located below the track-changing member 13, and the guide member 14 is used to control the traveling trolley 20 to switch tracks. Specifically, the guide member 14 is pivotally connected to the track-changing member 13 around the vertical direction DH between a third position and a fourth position. It should be noted that the guide member 14 at the third position closes the accommodating cavity 113a to prevent the traveling trolley 20 from passing through the accommodating cavity 113a, and the guide member 14 at the fourth position opens the accommodating cavity 113a to enable the traveling trolley 20 to pass through the accommodating cavity 113a. Figure 7 In the figure, the track-changing member 113 has a receiving cavity 113a. The number of first connecting ends 1131 of a single track-changing member 113 is two and they are spaced apart along the first horizontal direction D1. The track-changing member 113 also has a second connecting end 1132. It can be understood that the two first connecting ends 1131 are respectively connected to the first rails 11 adjacent to each other along the first horizontal direction D1, and the second connecting end 1132 is connected to the second rail 12. When the guide member 14 is in the third position, the receiving cavity 113a is closed, and the trolley 20 moves along the first horizontal direction D1, or in other words, the trolley 20 moves between the first rails 11 adjacent to each other along the first horizontal direction D1. When the guide member 14 is in the fourth position (see Figure 7 ), the passages between the adjacent first rails 11 along the first horizontal direction D1 are blocked, and the traveling trolley 20 can pass through the accommodating cavity 113a.

[0076] Please continue reading Figure 6 and Figure 7 The aerial suspension conveyor line 2 further includes a base 15, a driving member and a transmission member 17. Specifically, the base 15 is located above the track-changing member 13 and is connected to the first track 11 or the second track 12, for example Figure 6 In the figure, the cross-section of the base 15 is C-shaped, for example, it is made by cutting C-shaped steel. The base 15 is connected to the first track 11 and abuts against the track-changing member 113. A driving member (not shown) is connected to the base 15. The driving member has an actuator 16. The driving member can be constructed as a component with telescopic function such as an air cylinder, an oil cylinder, an electric cylinder, a telescopic rod, etc. The transmission member 17 is pivotally connected to the base 15 around the vertical direction DH. One end of the transmission member 17 is movably connected to the actuator 16, and the other end of the transmission member 17 is coaxially installed with the guide member 14, and the transmission member 17 is located above the guide member 14. For example, the driving member is constructed as a cylinder. After the actuator 16 is operated, it will drive the transmission member 17 to pivot relative to the base 15 around the vertical direction DH, thereby driving the guide member 14 coaxially installed therewith to pivot between the third position and the fourth position around the vertical direction DH relative to the base 15, so as to control the walking trolley 20 to switch tracks.

[0077] See also Figure 6 and Figure 8 Preferably, the second horizontal direction D2 is perpendicular to the first horizontal direction D1, and the second track 12 has the same structure as the first track 11. The aerial suspension conveyor line 1 further includes a retaining member 18, which is located inside the first track 11 and / or the second track 12 and abuts against the inner wall of the first track 11 and / or the second track 12 to prevent the first track 11 and / or the second track 12 from deforming. For example Figure 8 In the embodiment, the retaining member 18 is located inside the first rail 11, and the first rail 11 may be provided with a positioning hole suitable for the retaining member 18. Accordingly, the retaining member 18 may be constructed as a stepped shaft type. It can be understood that the outer diameter of the portion of the retaining member 18 located in the positioning hole is smaller than the outer diameter of the other portions. Furthermore, in order to reduce the difficulty of installing the retaining member 18 on the rail, the retaining member 18 may include a fixing portion and an adjusting portion. The adjusting portion is adjustably connected to the fixing portion along the axial direction of the retaining member 18 to control the size of the retaining member 18 along its own axial direction, thereby adapting to rails of different specifications. For example, the fixing portion and the adjusting portion are provided with internal and external threads that match each other. After the adjustment is completed, due to the self-locking of the internal and external threads, the adjusting portion and the fixing portion will not gather together or shrink, thereby maintaining the support state of the rail.

[0078] The present invention's overhead conveyor line controls the coordination of the compression members and the transmission belt at different wheel sets, preventing simultaneous power loss for both the first and second wheel sets. This ensures the trolley can smoothly pass through the accommodating cavity, completing track switching and effectively enhancing the operational flexibility of the belt-type overhead conveyor line. Furthermore, the guide members control the path of the wheel sets, further increasing the diversity of the trolley's operating paths.
