Description

Technical Field

[0001] The utility model relates to the technical field of sorting devices, in particular to a walking system of a mobile sorting device. Background Art

[0002] Cargo sorting is a core part of the logistics industry. During the shipping process, sorting devices need to be operated according to sorting tasks such as orders. To improve sorting efficiency, the sorting devices need to be able to deliver goods to two-dimensionally arranged grids. For example, patent CN 211282386 U discloses a turntable stacking lift sorting machine, which uses multiple cargo lifts that rotate with the turntable to perform cargo sorting operations. In this solution, due to structural limitations, the height of the cargo lifts is limited, and only limited cargo collection devices can be graded. If the structure is too high, the turntable will cause significant shaking when rotating, resulting in poor structural reliability and stability. Utility Model Content

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a walking system for a mobile sorting device that operates stably and can meet the needs of lifting and sorting in a large height range.

[0004] Technical Solution: To achieve the above-mentioned purpose, the utility model provides a traveling system for a mobile sorting device, wherein the mobile sorting device comprises a frame and a belt mechanism capable of being raised and lowered along the frame. The belt mechanism can carry the goods to be sorted and deliver the goods to the target delivery location. The belt mechanism comprises an upper traveling wheel mechanism and a lower traveling wheel mechanism respectively mounted on the upper and lower sides of the frame of the mobile sorting device; and further comprises upper and lower guide rails of a fixed layout.

[0005] The upper traveling wheel mechanism includes an upper wheel frame, on which an upper supporting wheel with a horizontal rotating shaft and an upper side wheel with a vertical rotating shaft are mounted; the upper supporting wheel contacts the top surface or the bottom surface of the upper guide rail; the upper side wheel contacts the side surface of the upper guide rail;

[0006] The lower walking wheel mechanism includes a lower wheel frame, on which a lower supporting wheel with a horizontal lower rotating shaft and a lower side wheel with a vertical rotating shaft are installed; the lower supporting wheel contacts the top surface or bottom surface of the lower guide rail; and the lower side wheel contacts the side surface of the lower guide rail.

[0007] The upper wheel frame and the lower wheel frame can be manufactured separately and fixed relative to the frame, or can be formed integrally with the frame.

[0008] Furthermore, the upper support wheel is located above the upper guide rail, and the lower support wheel is located above the lower guide rail. Thus, both the upper and lower travel wheel mechanisms can be detached from their respective guide rails from above, facilitating loading and unloading of the mobile sorting device. The mobile sorting device relies on its own weight to maintain contact with the upper and lower support wheels.

[0009] Furthermore, there is one upper guide rail; there are two upper side wheels, which are respectively placed on both sides of the upper guide rail.

[0010] Furthermore, the number of the lower guide rails is two; the lower wheel frame is provided with two lower support wheels respectively corresponding to the two lower guide rails;

[0011] There are two lower side wheels, both of which are placed between the two lower guide rails, and the two lower side wheels are in one-to-one contact with the two lower guide rails.

[0012] Furthermore, a plurality of upper running wheel mechanisms and / or lower running wheel mechanisms are mounted on the frame. This situation is applicable to the situation where the mobile sorting device is used alone.

[0013] Furthermore, multiple mobile sorting devices can be used in series, each equipped with only one set of upper and lower running wheel mechanisms. Since multiple mobile sorting devices are connected in series, all of them form a moving assembly that moves as a whole. This assembly, equipped with multiple upper and lower running wheel mechanisms, ensures stable movement while reducing the number of running wheel mechanisms used.

[0014] Furthermore, the upper guide rail and the lower guide rail are both closed circular rails, so that the mobile sorting device can move in a circular motion, and sorting grids can be set along the circular rails, so that the mobile sorting device can handle the sorting tasks of many orders.

[0015] Furthermore, the upper support wheel is connected to the upper wheel frame via a first wheel frame, and the first wheel frame is connected to the upper wheel frame via a first pin shaft, so that the first wheel frame can rotate along a vertical axis relative to the upper wheel frame.

[0016] Furthermore, the lower support wheel is connected to the lower wheel frame via a second wheel frame, and the second wheel frame is connected to the lower wheel frame via a second pin shaft, so that the second wheel frame can rotate along the vertical axis relative to the lower wheel frame.

[0017] Furthermore, the cross-sections of the upper wheel frame and the lower wheel frame are both U-shaped, that is, the upper wheel frame and the lower wheel frame respectively have a groove body, one end of the above-mentioned first wheel frame is placed in the groove body of the upper wheel frame, and one end of the above-mentioned second wheel frame is placed in the groove body of the lower wheel frame, so that the reliability of the connection can be guaranteed.

[0018] Furthermore, among the two upper wheels, one of the upper wheels is directly hinged to the upper wheel frame, and the other upper wheel is installed on a floating wheel frame. An elastic mechanism for applying elastic force to the floating wheel frame is connected between the floating wheel frame and the upper wheel frame.

[0019] Furthermore, the number of the upper guide rail and the number of the lower guide rail are both one, and the structure of the upper running wheel mechanism and the lower running wheel mechanism are the same.

[0020] Beneficial effects: The walking system of the mobile sorting device of the present invention has the following beneficial effects:

[0021] (1) By setting up upper and lower guide rails and installing upper and lower walking wheel mechanisms on the frame, stable support for the frame can be achieved, so that the frame can be set very high and not easy to shake. Each walking wheel mechanism contacts the corresponding guide rail through a rotatable wheel, which can effectively reduce the running resistance, so that the movement of the frame will not be stuck and the operation is smooth.

[0022] (2) The layout of single upper guide rail and double lower guide rail can improve the support stability of the mobile sorting device. The two lower support wheels are placed between the two lower guide rails, which can reduce the movement space occupied by the lower support wheels and make it difficult for foreign objects to be drawn into the lower support wheels.

[0023] (3) At the turning position of the guide rail, the upper support wheel and the lower support wheel respectively rotate adaptively relative to the upper wheel frame and the lower wheel frame to reduce turning resistance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] like Figure 1 The traveling system of the mobile sorting device shown in the figure comprises a frame 1 and a belt mechanism 6 that can be raised and lowered along the frame 1. The belt mechanism 6 can carry the goods to be sorted and deliver the goods to the target delivery location. The belt mechanism 6 comprises an upper traveling wheel mechanism 2 and a lower traveling wheel mechanism 3 respectively mounted on the upper and lower sides of the frame 1 of the mobile sorting device; and further comprises an upper guide rail 4 and a lower guide rail 5 of a fixed layout.

[0036] like Figure 2 、 4 As shown, the upper walking wheel mechanism 2 includes an upper wheel frame 21, on which an upper support wheel 22 with a horizontal rotating shaft and an upper side wheel 23 with a vertical rotating shaft are installed; the upper support wheel 22 contacts the top surface or bottom surface of the upper guide rail 4; the upper side wheel 23 contacts the side surface of the upper guide rail 4.

[0037] like Figure 3 、 5 As shown, the lower walking wheel mechanism 3 includes a lower wheel frame 31, on which a lower support wheel 32 with a horizontal lower shaft and a lower side wheel 33 with a vertical shaft are installed; the lower support wheel 32 contacts the top surface or bottom surface of the lower guide rail 5; and the lower side wheel 33 contacts the side surface of the lower guide rail 5.

[0038] The upper wheel frame 21 and the lower wheel frame 31 can be manufactured separately and fixed relative to the frame 1, or can be integrally formed with the frame 1.

[0039] In the above structure, by setting upper and lower guide rails and installing upper and lower walking wheel mechanisms on the frame 1, stable support of the frame 1 can be achieved, so that the frame 1 can be set very high and not easy to shake. Each walking wheel mechanism contacts the corresponding guide rail through a rotatable wheel, which can effectively reduce the running resistance, so that the movement of the frame 1 will not be stuck and the operation is smooth.

[0040] Preferably, the upper support wheel 22 is located above the upper guide rail 4; the lower support wheel 32 is located above the lower guide rail 5. In this way, both the upper and lower travel wheel mechanisms 2 and 3 can be detached from their respective guide rails from the upper side, making it easy to load and unload the mobile sorting device. The mobile sorting device relies on its own weight to maintain contact with the upper and lower support wheels 22 and 32.

[0041] In this embodiment, there is one upper guide rail 4; there are two upper side wheels 23, which are respectively placed on either side of the upper guide rail 4. There are two lower guide rails 5; the lower wheel frame 31 is mounted with two lower support wheels 32, which are respectively arranged corresponding to the two lower guide rails 5; correspondingly, there are two lower side wheels 33, which are both placed between the two lower guide rails 5, and the two lower side wheels 33 are in one-to-one contact with the two lower guide rails 5.

[0042] The above-mentioned layout of single upper guide rail and double lower guide rail can improve the support stability of the mobile sorting device. The two lower support wheels 32 are placed between the two lower guide rails 5, which can reduce the movement space occupied by the lower support wheels 32 and make it difficult for foreign objects to be drawn into the lower support wheels 32.

[0043] In one embodiment, the frame 1 is equipped with multiple upper running wheel mechanisms 2 and / or lower running wheel mechanisms 3. This configuration is applicable when the mobile sorting device is used alone. When there are multiple upper running wheel mechanisms 2, all upper running wheel mechanisms 2 are arranged along the extension direction of the upper guide rail 4. The same applies when there are multiple lower running wheel mechanisms 3.

[0044] In another embodiment, Figure 6 As shown, multiple mobile sorting devices can be used in series, each equipped with only one set of upper running wheel mechanisms 2 and one set of lower running wheel mechanisms 3. Since multiple mobile sorting devices are connected in series, all of them can form a moving assembly that moves as a whole. This entire assembly is equipped with multiple upper running wheel mechanisms 2 and lower running wheel mechanisms 3, which can ensure stable movement and reduce the number of running wheel mechanisms used.

[0045] Preferably, the upper guide rail 4 and the lower guide rail 5 are both closed circular rails, so that the mobile sorting device can move in a circular motion, and sorting grids can be set along the circular rails, so that the mobile sorting device can handle the sorting tasks of many orders.

[0046] Preferably, the upper support wheel 22 is connected to the upper wheel frame 21 via a first wheel frame 24, which is connected to the upper wheel frame 21 via a first pin 25, allowing the first wheel frame 24 to rotate along a vertical axis relative to the upper wheel frame 21. Similarly, the lower support wheel 32 is connected to the lower wheel frame 31 via a second wheel frame 34, which is connected to the lower wheel frame 31 via a second pin 35, allowing the second wheel frame 34 to rotate along a vertical axis relative to the lower wheel frame 31. The upper wheel frame 21 and the lower wheel frame 31 both have U-shaped cross-sections, meaning that each has a slot. One end of the first wheel frame 24 is positioned within the slot of the upper wheel frame 21, and one end of the second wheel frame 34 is positioned within the slot of the lower wheel frame 31, thereby ensuring reliable connection.

[0047] By adopting the above structure, the upper support wheel 22 and the lower support wheel 32 can be adaptively rotated relative to the upper wheel frame 21 and the lower wheel frame 31 respectively at the turning position of the guide rail, thereby reducing turning resistance.

[0048] Example 2

[0049] like Figure 7 The traveling system of the mobile sorting device shown in the figure comprises a frame 1 and a belt mechanism 6 that can be raised and lowered along the frame 1. The belt mechanism 6 can carry the goods to be sorted and deliver the goods to the target delivery location. The belt mechanism 6 comprises an upper traveling wheel mechanism 2 and a lower traveling wheel mechanism 3 respectively mounted on the upper and lower sides of the frame 1 of the mobile sorting device; and further comprises an upper guide rail 4 and a lower guide rail 5 of a fixed layout.

[0050] The upper walking wheel mechanism 2 includes an upper wheel frame 21, on which an upper support wheel 22 with a horizontal rotating shaft and an upper side wheel 23 with a vertical rotating shaft are installed; the upper support wheel 22 contacts the top surface or bottom surface of the upper guide rail 4; the upper side wheel 23 contacts the side surface of the upper guide rail 4.

[0051] The lower walking wheel mechanism 3 includes a lower wheel frame 31, on which a lower support wheel 32 with a horizontal lower shaft and a lower side wheel 33 with a vertical shaft are installed; the lower support wheel 32 contacts the top surface or bottom surface of the lower guide rail 5; the lower side wheel 33 contacts the side surface of the lower guide rail 5.

[0052] In this embodiment, the number of the upper guide rail 4 and the number of the lower guide rail 5 are both one, and the upper running wheel mechanism 2 and the lower running wheel mechanism 3 have the same structure. The structure of the upper running wheel mechanism 2 is described below.

[0053] In the upper walking wheel mechanism 2, the upper support wheel 22 is connected to the upper wheel frame 21 via a first wheel frame 24. The first wheel frame 24 is connected to the upper wheel frame 21 via a first pin shaft 25, so that the first wheel frame 24 can rotate along the vertical axis relative to the upper wheel frame 21. In addition, one of the upper side wheels 23 is directly hinged on the upper wheel frame 21, and the other upper side wheel 23 is installed on a floating wheel frame 26. The floating wheel frame 26 can rotate relative to the upper wheel frame 21, and an elastic mechanism 27 is provided between the upper wheel frame 21 and the floating wheel frame 26. The elastic mechanism 27 applies a force to the floating wheel frame 26, so that the two upper support wheels 22 have a tendency to move closer to each other. In this way, the two upper support wheels 22 can be tightly attached to the two sides of the upper guide rail 4 under the force of the elastic mechanism 27. When the width of the upper guide rail 4 changes, the distance between the two upper support wheels 22 can change adaptively.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
