Description

Technical Field

[0001] The present invention relates to the technical field of parcel sorting, and in particular to a sorting trolley and a sorting device. Background Art

[0002] There are many types of item sorting devices on the market at present. Among them, the slider sorting machine has a wide range of application scenarios due to its strong adaptability. The slider sorting machine is generally arranged in a straight line, and the upper and lower double layers are connected by arc segments at both ends. The sorting trolleys are connected end to end to form a loop (sorting trolley group).

[0003] Generally, the upper layer of the loop is the sorting outbound journey, and the lower layer of the loop is the sorting return journey. When the sorting trolley passes through the upper layer, the slider slides along the sorting direction and pushes the items on the upper end surface of the sorting trolley out of the sorting trolley to sort the items. Then the sorting trolley returns to the upper layer of the loop after passing through the sorting return journey of the lower layer in an empty state. The existing problem is that the sorting trolley is in an empty state during the return journey stage, resulting in that the sorting trolley can only achieve single-layer sorting, and the sorting efficiency is relatively low.

[0048] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0049] Embodiment 1

[0050] Generally, multiple sorting carts are connected end to end in sequence to form a sorting cart group. The sorting cart group is generally arranged in a loop shape. Each sorting cart moves in a loop along the loop, and completes the sorting operation of the items during the movement. Specifically, the sorting cart is a slider-type sorting cart. When the sorting cart runs along the loop track to a specified position, the slider moves along the sorting direction to unload the items.

[0051] As Figure 1 shown, the upper layer of the loop is defined as the sorting outbound journey, and the lower layer is defined as the sorting return journey. Figure 1 The clockwise direction of the middle loop is the conveying direction of the sorting cart. When the sorting cart passes through the upper layer, it can unload the items. Then the sorting cart passes through the sorting return journey empty, so that the sorting cart can only achieve single-layer sorting, and the sorting efficiency is relatively low.

[0052] To solve the above problems, as Figures 2 - 4 shown, this embodiment discloses a sorting cart. The sorting cart includes a frame 1 and a double-headed sorting block 3. A carrier 2 and a traveling assembly 11 are fixedly arranged on the frame 1. The carrier 2 has an upper side bearing surface 21 and a lower side bearing surface 22. The double-headed sorting block 3 includes an upper side sorting part 31 and a lower side sorting part 35. The upper side sorting part 31 is slidably arranged above the upper side bearing surface 21, and the lower side sorting part 35 can be slidably arranged below the lower side bearing surface 22. When the sorting cart travels along the conveying direction on the sorting outbound journey through the traveling assembly 11, the double-headed sorting block 3 can move along the sorting direction (the length direction of the frame 1) to push out the items located on the upper side bearing surface 21. When the sorting cart travels along the conveying direction on the sorting return journey through the traveling assembly 11, the double-headed sorting block 3 can move along the sorting direction to push out the items located on the lower side bearing surface 22.

[0053] The double-layer sorting process of the sorting trolley is as follows: When the sorting trolley travels to the sorting position during the sorting outbound journey, the double-headed sorting part 3 slides along the sorting direction, so that the upper sorting part 31 and the lower sorting part 35 move synchronously, and the upper sorting part 31 pushes the items on the upper bearing surface 21 out of the sorting trolley. When the sorting trolley travels to the sorting position during the sorting return journey, the sorting trolley rotates 180°. At this time, the lower bearing surface 22 and the lower sorting part 35 thereon face upward, and the items can be placed on the lower bearing surface 22. The double-headed sorting block 3 slides along the sorting direction, so that the lower sorting part 35 pushes the items on the lower bearing surface 22 out of the sorting trolley. The sorting trolley can achieve double-layer sorting during the sorting outbound journey and the sorting return journey through the double-headed sorting block 3, improving the sorting efficiency of the sorting trolley.

[0054] At both ends of the bottom of the vehicle frame 1 of this embodiment along its sorting direction, traveling components 11 are provided. Through the traveling components 11, the vehicle frame 1 can reciprocally move between the sorting outbound journey and the sorting return journey along the conveying direction.

[0055] Specifically, traveling components 11 are installed at both ends of the vehicle frame 1 through end support plates. The traveling components 11 include traveling wheels 111 and a traction component. Multiple sorting trolleys are connected by the traction component and the driving of the sorting trolleys is realized. Specifically, the traction component includes a driving sprocket, a driven sprocket, and a traction chain 112. The driving sprocket is driven by a driving device, and the sorting trolley is connected to the traction chain 112. In this embodiment, the chain shaft of the traction chain 112 is rotatably connected to the end support plate of the vehicle frame 1 of the sorting trolley, and the traveling wheels 111 are rotatably arranged on the chain shaft where the traction chain 112 is rotatably connected to the end support plate. When the driving device drives the driving sprocket to rotate, the sorting trolley is driven by the traction chain 112.

[0056] As Figure 2 shown, a first connection part 201 is provided at one end of the upper bearing surface 21 in the conveying direction, and a second connection part 202 is provided at the other end of the upper bearing surface 21 in the conveying direction. A first connection part 201 is provided at one end of the lower bearing surface 22 in the conveying direction, and a second connection part 202 is provided at the other end of the lower bearing surface 22 in the conveying direction.

[0057] The first connection part 201 on the upper side of one sorting trolley can be connected and cooperated with the second connection part 202 on the upper side of another sorting trolley, so that the upper bearing surfaces 21 of two adjacent sorting trolleys are connected and flush. The first connection part 201 on the lower side of one sorting trolley can be connected and cooperated with the second connection part 202 on the lower side of another sorting trolley, so that the lower bearing surfaces 22 of two adjacent sorting trolleys are connected and flush.

[0058] In this embodiment, the upper bearing surfaces 21 of two adjacent sorting trolleys are connected and flush, and the lower bearing surfaces 22 are also connected and flush. This can prevent small-sized items from falling between two adjacent sorting trolleys during double-layer sorting. Thus, the sorting trolley can be used for sorting both large-sized and small-sized items, with strong versatility and a wide range of applications.

[0059] Specifically, as Figure 2 shown, the upper bearing surface 21 and the lower bearing surface 22 are respectively provided with plate-shaped first connecting parts 201 extending outwards. The second connecting part 202 is in a stepped shape. The first connecting part 201 of the upper bearing surface 21 of one sorting trolley can be stacked above the second connecting part 202 of the upper bearing surface 21 of another sorting trolley, and the first connecting part 201 of the lower bearing surface 22 of one sorting trolley can be stacked above the second connecting part 202 of the lower bearing surface 22 of another sorting trolley.

[0060] As Figures 3 - 5 shown, the double-headed double-slider 3 is an integral structure, enabling the upper sorting part 31 and the lower sorting part 35 to simultaneously move synchronously along the sorting direction relative to the carrier 2. The double-headed sorting block 3 of this embodiment further includes a first connecting part 32, a first guiding part 33, and a second connecting part 34 that are connected in sequence. The upper sorting part 31 is connected to the first connecting part 32, and the lower sorting part 35 is connected to the second connecting part 34. The first guiding part 33 is slidably engaged with the carrier 2, and the first connecting part 32 and the second connecting part 34 are wrapped around the side surface of the carrier 2. The double-headed sorting block 3 can wrap around the vehicle frame 1 in an open-loop manner, improving the installation stability of the double-headed sorting block 3 on the vehicle frame 1 and facilitating the stable sliding of the double-headed sorting block 3 along the sorting direction on the carrier 2.

[0061] Specifically, the part where the first connecting part 32 and the second connecting part 34 are connected is recessed inwards towards the carrier 2 to form a U-shaped structure, namely the first guiding part 33. The side surface of the carrier 2 correspondingly has an inwardly concave third sliding groove 203, and the first guiding part 33 is slidably engaged with the third sliding groove 203, further improving the installation stability of the double-headed sorting block 3 on the vehicle frame 1 and facilitating the stable sliding of the double-headed sorting block 3 along the sorting direction on the carrier 2.

[0062] Furthermore, as Figure 5As shown, a first slider 311 is provided on the upper sorting part 31, and a first chute 211 which is slidably engaged with the first slider 311 is provided on the upper bearing surface 21. The first chute 211 extends along the sorting direction to prevent the upper sorting part 31 from separating from the upper bearing surface 21 of the bearing member 2. A second slider 351 is provided on the lower sorting part 35, and a second chute 221 which is slidably engaged with the second slider 351 is provided on the lower bearing surface 22. The second chute 221 extends along the sorting direction to prevent the lower sorting part 35 from separating from the lower bearing surface 22 of the bearing member 2.

[0063] Preferably, the first chute 211 and the second chute 221 have the same structure and are both T-shaped chutes. Correspondingly, the first slider 311 and the second slider 351 are both T-shaped sliders. Through the sliding fit of the T-shaped chute and the T-shaped slider, not only can the stable movement of the double-headed sorting block 3 relative to the bearing member 2 be ensured, but also the derailment of the first slider 311 and the first chute 211 and the second slider 351 and the second chute 221 can be prevented, ensuring the stability of the sliding structure.

[0064] As Figure 5 shown, the upper sorting part 31 and the first connecting part 32 form a first connecting groove 310 at the second connecting part 202 of the upper bearing surface 21. The first connecting part 201 of one sorting trolley can extend into the first connecting groove 310 of another sorting trolley. The lower sorting part 35 and the second connecting part 34 form a second connecting groove 320 at the second connecting part 202 of the lower bearing surface 22. The first connecting part 201 of one sorting trolley can extend into the second connecting groove 320 of another sorting trolley. This method can ensure that the upper bearing surfaces 21 of the bearing members 2 on two sorting trolleys are connected, the lower bearing surfaces 22 of the bearing members 2 on two sorting trolleys are connected, and also ensure that the upper sorting parts 31 of two sorting trolleys are in close contact and the lower sorting parts 35 of two sorting trolleys are in close contact.

[0065] Preferably, sorting slopes 30 are provided at both ends of the upper sorting part 31 and the lower sorting part 35 along the sorting direction. The sorting slopes 30 can form a surface push when pushing and sorting articles, improving the pushing force.

[0066] When the sorting trolley is used for sorting thin or soft-packaged articles, in order to prevent the thin articles from being stuck between the upper sorting part 31 and the upper bearing surface 21 or between the lower sorting part 35 and the lower bearing surface 22, as Figure 2 、 Figure 3 and Figure 5As shown, a plurality of first protrusions 20 are respectively provided on the upper bearing surface 21 and the lower bearing surface 22, and the plurality of first protrusions 20 are arranged at intervals in the conveying direction. A plurality of second protrusions 330 are arranged at intervals in the conveying direction on the bottom surfaces of the upper sorting part 31 and the lower sorting part 35, and the second protrusions 330 are arranged staggered with the corresponding first protrusions 20. That is, during the upper-layer sorting process, the first protrusions 20 and the second protrusions 330 between the upper sorting part 31 and the upper bearing surface 21 are embedded with each other, avoiding thin parts being stuck between the upper sorting part 31 and the upper bearing surface 21. During the lower-layer sorting process, the first protrusions 20 and the second protrusions 330 between the lower sorting part 35 and the lower bearing surface 22 are embedded with each other, avoiding thin parts being stuck between the lower sorting part 35 and the lower bearing surface 22.

[0067] Specifically, the first protrusion 20 can be a rib running across the upper bearing surface 21 or the lower bearing surface 22 in the sorting direction, and multiple ribs on the upper bearing surface 21 and the lower bearing surface 22 are arranged at intervals in the conveying direction. In other embodiments, the first protrusion 20 can also be formed by arranging a plurality of convex blocks at intervals in the sorting direction. The second protrusion 330 can be a rib or a convex block, as long as it can prevent thin parts from being stuck under the sorting block 3, and no further examples will be given here.

[0068] As Figures 2 - 5 shown, the sorting trolley further includes a driving assembly 4, and the driving assembly 4 is a dial wheel assembly, specifically including an unloading lever 41 and an unloading dial wheel 42. One ends of the two unloading levers 41 are respectively fixedly arranged on the upper sorting part 31 and the lower sorting part 35, and the other ends respectively extend out of the corresponding upper sorting part 31 and the lower sorting part 35. The unloading dial wheel 42 is rotatably arranged at the other end of the unloading lever 41 and is located above the corresponding upper sorting part 31 or the lower sorting part 35. The unloading dial wheel 42 can cooperate with the unloading track 400 of the sorting device (refer to Figure 6 ) to drive the double-headed sorting block 3 to slide in the sorting direction.

[0069] It should be noted that there are two dial wheel assemblies in this embodiment, which are respectively installed on the upper sorting part 31 and the lower sorting part 35. When the sorting trolley moves in the sorting outgoing journey in the conveying direction, the unloading dial wheel 42 on the lower sorting part 35 will roll and contact with the upper-layer track. When the sorting trolley moves in the sorting return journey in the conveying direction, the unloading dial wheel 42 on the upper sorting part 31 will roll and contact with the lower-layer track, thereby driving the double-headed sorting block 3 to move and pushing the item out of the sorting trolley, thus completing the double-layer sorting of the item.

[0070] As Figure 6 and Figure 7As shown in the figure, this embodiment also provides a sorting device, which includes a track and the above sorting cart. A plurality of sorting carts are connected in sequence to form a sorting cart group 100, and the sorting cart group 100 can move along the track. By applying the above sorting cart, this sorting device can not only adapt to items of different sizes, but also is suitable for sorting thin or soft-packaged items, with strong versatility and a wide range of applications. At the same time, it can achieve double-layer sorting during the sorting outbound and inbound trips, improving the sorting efficiency of the sorting device.

[0071] Specifically, the track includes a traveling track (not shown in the figure) and an unloading track 400. There are two unloading tracks 400, and the two unloading tracks 400 are respectively installed on the lower end surfaces of the upper layer and the lower layer of the loop line. When the sorting cart group 100 runs to the unloading track 400 on the upper layer of the loop line, the unloading track 400 can cooperate with the dial wheel assembly on the lower side of the sorting cart and provide sorting power for the double-headed sorting block 3, so that the upper sorting part 31 slides along the sorting direction and pushes the items on the upper bearing surface 21 out of the sorting cart. Similarly, when the sorting cart group 100 runs to the unloading track 400 on the lower layer of the loop line, the unloading track 400 can cooperate with the dial wheel assembly on the upper side of the sorting cart and provide sorting power for the double-headed sorting block 3, so that the lower sorting part 35 slides along the sorting direction and pushes the items on the lower bearing surface 22 out of the sorting cart.

[0072] As Figure 6 shown, the unloading track 400 includes a mounting seat 401, a turnout 402, a sorting track 403, and a transition track 404. The four sorting tracks 403 are fixed on the mounting seat 401 in an X shape through a transition track 404, and turnouts 402 that can be rotated and adjusted are provided at both sorting tracks 403 at the front end of the conveying direction.

[0073] When sorting items are needed, the turnout 402 rotates and is connected to the sorting track 403. Specifically, the unloading dial 42 of the dial wheel assembly can slide relative to the vehicle frame 1 under the guidance of the turnout 402 and the sorting track 403, so as to push the items on the upper bearing surface 21 or the lower bearing surface 22 of the carrier 2 out of the vehicle frame 1, completing the sorting of the items.

[0074] When sorting items are not needed, the turnout 402 remains straight and is not connected to the sorting track 403, and the unloading dial 42 walks along the turnout 402 and remains stationary relative to the vehicle frame 1.

[0075] Embodiment Two

[0076] As Figure 8 shown, the main difference between this embodiment and Embodiment One is that the structures of the first connection part 201 and the second connection part 202 are different, specifically as follows:

[0077] The first connecting part 201 is a first inclined surface, and the second connecting part 202 is a second inclined surface that can cooperate with the first inclined surface. The first connecting part 201 of the upper bearing surface 21 of one sorting trolley can be stacked above the second connecting part 202 of the upper bearing surface 21 of another sorting trolley, and the first connecting part 201 of the lower bearing surface 22 of one sorting trolley can be stacked above the second connecting part 202 of the lower bearing surface 22 of another sorting trolley.

[0078] In this embodiment, the double-headed sorting block 3 further includes a third connecting part 36, a second guiding part 37, and a fourth connecting part 38 that are connected in sequence. One end of the third connecting part 36 is connected to the lower sorting part 35, and the other end is connected to the second guiding part 37. The second guiding part 37 is slidably matched with the other side surface of the bearing part 2. The third connecting part 36 and the fourth connecting part 38 are covered on the other side of the bearing part 2, so that the double-headed sorting block 3 can be closed-loop wrapped on the vehicle frame 1, improving the installation stability of the double-headed sorting block 3 on the vehicle frame 1, and at the same time facilitating the stable sliding of the double-headed sorting block 3 on the bearing part 2 along the sorting direction.

[0079] Specifically, the upper sorting part 31 and the first connecting part 32 form a second inclined surface at the second connecting part 202 of the upper bearing surface 21, and the upper sorting part 31 and the fourth connecting part 38 form a first inclined surface at the first connecting part 201 of the upper bearing surface 21. The lower sorting part 35 and the second connecting part 34 form a second inclined surface at the second connecting part 202 of the lower bearing surface 22, and the lower sorting part 35 and the third connecting part 36 form a first inclined surface at the first connecting part 201 of the lower bearing surface 22.

[0080] When two sorting trolleys are connected, the first inclined surface on the upper side of one sorting trolley can be stacked on the second inclined surface on the upper side of another sorting trolley, and the first inclined surface on the lower side of one sorting trolley can be stacked on the second inclined surface on the lower side of another sorting trolley, so as to minimize the distance between the two sorting trolleys on the upper bearing surface 21 and between the two sorting trolleys on the lower bearing surface 22, and prevent items from falling between the two sorting trolleys during double-layer sorting.

[0081] In addition, the part where the third connecting part 36 is connected to the fourth connecting part 38 is recessed inward towards the bearing part 2 to form a U-shaped structure, that is, the second guiding part 37. The other side surface of the bearing part 2 correspondingly has an inwardly concave fourth sliding groove 204, and the second guiding part 37 is slidably matched with the fourth sliding groove 204, further improving the installation stability of the double-headed sorting block 3 on the vehicle frame 1, and at the same time facilitating the stable sliding of the double-headed sorting block 3 on the bearing part 2 along the sorting direction.

[0082] The above embodiments only illustrate the basic principles and features of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed.
