Description

Technical Field

[0001] This utility model belongs to the field of logistics sorting technology, specifically relating to a accordion-style sorting cart connection structure. Background Technology

[0002] In the logistics sorting field, tipper sorters, as a highly efficient automated device, are widely used in parcel sorting operations in e-commerce warehousing and express delivery centers. Their core working principle is to achieve directional delivery of parcels through a tilting tray mechanism, featuring high sorting efficiency and wide adaptability to various goods. The sorting cart, as the core execution unit of the tipper sorter, directly affects sorting efficiency and reliability. Existing sorting carts typically consist of a chassis structure, drive system, positioning device, cart cover, and tilting unloading structure.

[0003] In the current operating conditions, the sorting trolleys in the tipping machine are driven by a synchronous motor directly below the track for linear motion, so each trolley has a secondary permanent magnet fixed at its bottom. However, during the operation of the sorting trolleys, if there are multiple packages on the trolley or the packages are not arranged in a standardized manner, the packages on the sorting trolley can easily fall between adjacent sorting trolleys, thus affecting the normal operation of the tipping machine.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1 , 2 As shown in Figures 1 and 3, an accordion-style sorting trolley connection structure is used to connect two adjacent sorting trolleys, including a dust cover 2 and a composite pull rod 3.

[0027] like Figure 4 As shown, the dust cover 2 adopts a triangular accordion-style telescopic structure, which can adaptively extend and retract and bend in different directions according to the relative position changes of two adjacent sorting carts. The dust cover 2 includes multiple telescopic units connected in sequence. The telescopic unit includes a frame 2-1 and two flexible layers 2-2; both the frame 2-1 and the flexible layers 2-2 are triangular strip structures, that is, formed by two straight structures connected at a certain angle. The width of the straight structure of the flexible layer 2-2 is greater than the width of the straight structure of the frame 2-1.

[0028] The outer edges of both flexible layers 2-2 are connected to the skeleton 2-1. The telescopic unit can extend or shorten through the opening and closing movement of the two flexible layers 2-2. The inner edges of the flexible layers 2-2 on adjacent sides of two adjacent telescopic units are connected.

[0029] The dust cover 2 has its pointed corners facing upwards, creating a wraparound, downward-sloping guide structure on its top surface. Specifically, the pointed corners of the dust cover 2 are the connecting points of the two straight structures of the frame 2-1. The bottom of the dust cover 2 is open, allowing the composite pull rod 3 to be inserted into its inner cavity through this opening.

[0030] The width of the bottom of the dust cover 2 is greater than the width of the top slot of the sorting machine track. Therefore, the dust cover 2 can completely cover the top slot of the sorting machine track. Thus, when a package falls between two sorting carts, it will slide out to both sides along the package sliding guide structure on the top surface of the dust cover 2, thereby preventing the package from continuously getting stuck between the two sorting carts or falling into the sorting track, and thus improving the stability of the sorting machine during continuous operation.

[0031] In some embodiments, the skeleton 2-1 adopts a rod-like structure.

[0032] In some embodiments, the flexible layer is made of elastic dustproof cloth.

[0033] like Figure 5 As shown, the composite pull rod 3 is located inside the dust cover 2 and can adaptively extend and retract as the relative positions of two adjacent sorting carts change, providing support for the dust cover 2. The composite pull rod includes multiple connecting rods 3-2 and multiple tension springs 3-1 connected alternately in sequence. The number of tension springs 3-1 is one more than the number of connecting rods 3-2; therefore, both ends of the composite pull rod are tension springs 3-1.

[0034] The tension spring 3-1 includes a spring body and two spring fixing discs 3-3. The two spring fixing discs 3-3 are respectively fixed to both ends of the spring body. The two ends of the connecting rod 3-2 are respectively fixed to the spring fixing discs 3-3 of the two tension springs 3-1 that are directly opposite each other. Multiple tension springs 3-1 and multiple connecting rods 3-2 are alternately connected along the length of the dust cover 2.

[0035] In some embodiments, the number of connecting rods 3-2 is two.

[0036] Threaded holes are provided on both sides of the connecting rod 3-2; screws are provided on both sides of the spring fixing plate 3-3. The spring body is connected to the connecting rod 3-2 through the spring fixing plate 3-3. The screws on both sides of the spring fixing plate 3-3, located between the tension spring 3-1 and the connecting rod 3-2, correspond to the threaded holes on the connecting rod 3-2 and the tension spring 3-1, respectively, thereby linearly connecting the multiple tension springs 3-1 in the composite tie rod 3.

[0037] In this embodiment, the wire diameter of the tension spring 3-1 is one of 1.5mm, 1.8mm, 2mm, or 2.2mm. The spring fixing plate 3-3 is hexagonal on the side opposite to the tension spring 3-1, with a side length of 15mm and a diameter of 27mm.

[0038] In this embodiment, each sorting trolley is equipped with a trolley cover plate 1. The trolley cover plate 1 is located above the frame of the sorting trolley and below the flip-down packaging structure. The trolley cover plate 1 includes a base plate 1-1 and vertically arranged end connecting plates 1-2 installed at both ends of the base plate 1-1 along its length. Multiple mounting holes 1-3 are provided at different positions on the top surface of the base plate 1-1. The mounting holes 1-3 are used to fix the loading trolley.

[0039] The two ends of the accordion-style sorting trolley connection structure are respectively connected to the opposite ends of the trolley cover plates 1 on the two adjacent sorting trolleys.

[0040] The specific connection method is as follows: the end connecting plate 1-2 is provided with two first through holes 1-4 and one second through hole 1-5. The second through hole 1-5 and the two first through holes 1-4 are arranged in an isosceles triangle, and the second through hole 1-5 is located above the middle position of the two first through holes 1-4.

[0041] Both ends of the dust cover 2 are provided with triangular connecting pieces; two third through holes 2-3 are opened on the triangular connecting pieces. The two first through holes 1-4 on the end connecting plate 1-2 correspond to the two third through holes 2-3 on the triangular connecting pieces and are fixed by bolts and nuts.

[0042] The second through hole 1-5 on the end connecting plate 1-2 corresponds to the screw position on the spring fixing plate 3-3 located at both ends of the composite tie rod 3, and is fixed by nuts.

[0043] The working principle of this embodiment is as follows:

[0044] When the sorting trolley reaches the uphill position, the trolley in front enters the ramp while the trolley behind has not yet entered the ramp. The distance between adjacent trolleys will decrease, which will cause the spring body in the composite tie rod to shorten.

[0045] When the sorting trolley reaches the downhill position, the trolley in front leaves the slope while the trolley behind has not yet left the slope. The distance between adjacent trolleys will increase, which will cause the spring body in the composite tie rod to extend.

[0046] Example 2

[0047] A flip-top sorting machine includes a circular track and a queue of sorting carts that circulate on the circular track. The queue of sorting carts includes multiple sorting carts connected sequentially. Adjacent sorting carts are connected by ball joints. Each sorting cart has a cart cover. The cart cover is located above the top slot of the circular track. The cart covers on adjacent sorting carts are connected by an accordion-type sorting cart connection structure provided in Embodiment 1.
