Description

Technical Field

[0001] The utility model relates to the technical field of warehousing and logistics, in particular to a sorting system. Background Art

[0002] At present, the matrix one-to-four sorting system is widely used in sorting operation scenarios, such as Figure 1 and Figure 2 As shown, the one-to-four sorting system is mainly composed of an input conveyor line 10, four output conveyor lines, a personnel operation station, and an automatic sorting unit. The input conveyor line 10 is located at a high position, and the four output conveyor lines are grouped in pairs. The two groups of output conveyor lines are spaced along the conveying direction of the input conveyor line 10. Each group of conveyor lines includes an upper output conveyor line 20 and a lower output conveyor line 30 distributed up and down. The input conveyor line 10 is connected to the upper output conveyor line 20 through an upper slide 40, and the input conveyor line 10 is connected to the lower output conveyor line 30 through a lower slide 50. When the goods are transported through the input conveyor line 10 located at a high position, the operator at the personnel operation station or the automatic sorting unit will initially sort the goods according to the destination flow direction according to the destination information of the goods, and divide them into four flow directions. That is, the goods are manually sorted or automatically sorted by an automatic sorting unit to the slides of the upper output conveyor line 20 and the lower output conveyor line 30 on both sides, and the goods slide and converge to the corresponding upper output conveyor line 20 or the lower output conveyor line 30 on the slide surface by their own gravity without power intervention.

[0003] The existing one-to-four matrix system is difficult to meet the needs of fragile items such as wine and beverages. In particular, the lower slide 50 connecting the high-level input conveyor line 10 and the lower output conveyor line 30 is to bring the goods from the input conveyor line 10 at a height of 3100mm to the lower output conveyor line 30 at a height of 500mm in a certain space. The goods slide down the lower slide 50 with a large height difference. The goods roll and collide during the sliding process, and the impact force is large, which will cause damage to the goods, resulting in the need for additional offline personnel to sort and carry out these fragile items.

[0021] The upper slide and the lower slide corresponding to the same sorting work station are respectively located on both sides of the input conveying line along the width direction.

[0022] As a preferred technical solution of the sorting system, each of the sorting workstations is provided with an automatic sorting unit; and a manual sorting workstation is also provided between two of the sorting workstations.

[0023] Beneficial effects of the utility model:

[0024] The utility model provides a sorting system. Firstly, a lower slide connects a corresponding sorting workstation and a lower output conveying line in a group of output conveying lines far from the corresponding sorting workstation. Compared with the prior art in which the lower slide connects the corresponding sorting workstation and the lower output conveying line in a group of output conveying lines close to the corresponding sorting workstation, the length of the lower slide is increased and the slope is reduced. Secondly, the lower slide comprises an unpowered receiving section and a powered transmission section which are sequentially arranged along the direction from the input transmission line to the lower transmission line. The unpowered receiving section is used for receiving goods pushed to the entrance of the lower slide by an automatic sorting unit or manually. The goods can slide down along the unpowered receiving section to the powered transmission section. The powered transmission section is used for transmitting the goods to the lower output conveying line. The transmission speed of the powered transmission section can be adjusted, and the initial speed of the powered transmission section matches the speed of the goods when sliding out of the unpowered receiving section. By setting up an unpowered receiving section, it can be ensured that the goods slide smoothly from the sorting work station to the lower slideway. By setting up a powered transmission section and matching its initial speed with the speed of the goods when they slide out of the unpowered receiving section, the goods sliding out of the unpowered receiving section can be stably received, and then the goods can be sent to the lower output conveyor line at a certain speed. This can effectively alleviate the impact of the height difference between the input conveyor line and the lower output conveyor line on the goods, reduce the risk of damage to the goods, and at the same time save manual sorting and handling work, reduce labor intensity, and improve sorting efficiency.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] The utility model embodiment provides a sorting system, such as Figure 3 and Figure 4 As shown, the sorting system includes an input conveyor line 10, two groups of output conveyor lines and two groups of slideways, wherein the input conveyor line 10 is located at a high position, and its height is about 3100mm; the input conveyor line 10 extends along a first direction, and two sorting workstations spaced along the first direction are arranged on the input conveyor line 10. Both groups of output conveyor lines are located below the input conveyor line 10, and are spaced along the first direction, and the two sorting workstations are located between the two groups of output conveyor lines; each group of output conveyor lines includes an upper output conveyor line 20 and a lower output conveyor line 30 distributed up and down, the height of the upper output conveyor line 20 is about 1800mm, and the height of the lower output conveyor line 30 is about 500mm; the upper output conveyor line 20 and the lower output conveyor line 30 both extend along a second direction, and the first direction and the second direction are distributed at an angle. In this embodiment, the angle between the first direction and the second direction is 90°, but it is not limited to this, and can also be greater than 90° or less than 90°. The two groups of slides correspond to the two sorting workstations one by one, and each group of slides includes an upper slide 40 and a lower slide 50. The upper slide 40 is used to connect the corresponding sorting workstation and an upper output conveying line 20 in a group of output conveying lines closer to the corresponding sorting workstation, and the lower slide 50 is used to connect the corresponding sorting workstation and a lower output conveying line 30 in a group of output conveying lines farther from the corresponding sorting workstation; the upper slide 40 and the lower slide 50 in a group of slides are respectively located on both sides of the input conveying line 10 along the width direction.

[0040] The sorting station is provided with an automatic sorting unit 60, and a manual sorting station is also provided between the two sorting stations. When the goods arrive at the sorting station along the input conveying line 10, the automatic sorting unit 60 or the manual sorting unit pushes the goods to the entrance of the corresponding upper slide 40 or the entrance of the lower slide 50 according to the goods information, and the goods slide along the upper slide 40 to the corresponding upper output conveying line 20 or slide along the lower slide 50 to the corresponding lower output conveying line 30. The goods can be diverted from the input conveying line 10 to the upper output conveying line 20 and the lower output conveying line 30 in one group of output conveying lines and the upper output conveying line 20 and the lower output conveying line 30 in another group of output conveying lines, that is, the sorting system of this embodiment is a one-to-four sorting system.

[0041] In this embodiment, the lower slide 50 connects the corresponding sorting workstation and the lower output conveyor line 30 in a group of output conveyor lines that is far away from the corresponding sorting workstation. Compared with the prior art in which the lower slide 50 connects the corresponding sorting workstation and the lower output conveyor line 30 in a group of output conveyor lines that is close to the corresponding sorting workstation, the length of the lower slide 50 is increased and the slope is reduced.

[0042] Furthermore, in this embodiment, the lower slide 50 includes an unpowered receiving section 51 and a powered transmission section 52 which are arranged in sequence along the direction from the input conveyor line 10 to the lower conveyor line. The unpowered receiving section 51 is used to receive the goods pushed to the entrance of the lower slide 50 by the automatic sorting unit 60 or manually. The goods can slide down along the unpowered receiving section 51 to the powered transmission section 52. The powered transmission section 52 is used to transmit the goods to the lower output conveyor line 30. The transmission speed of the powered transmission section 52 can be adjusted, and the initial speed of the powered transmission section 52 matches the speed of the goods when they slide out of the unpowered receiving section 51. By providing an unpowered receiving section 51, it can be ensured that the goods can slide smoothly from the sorting work station to the lower slide 50. By providing a powered transmission section 52 and matching its initial speed with the speed of the goods when they slide out of the unpowered receiving section 51, the goods sliding out of the unpowered receiving section 51 can be stably received and then sent to the lower output conveyor line 30 at a certain speed. This can effectively alleviate the impact of the height difference between the input conveyor line 10 and the lower output conveyor line 30 on the goods, reduce the risk of damage to the goods, and at the same time save manual sorting and handling work, reduce labor intensity, and improve sorting efficiency.

[0043] like Figure 5 and Figure 6As shown, the unpowered receiving section 51 is an unpowered roller conveyor, including a plurality of rollers 511 arranged at intervals along the conveying direction of the lower slideway 50. The unpowered roller conveyor can not only stably receive the goods and avoid the impact of the goods, but also ensure that the goods slide down smoothly on it. In this embodiment, the spacing between two adjacent rollers 511 is 50mm-60mm, preferably 55mm; the outer diameter of the roller 511 is 50mm-51mm, preferably 50.8mm. In this embodiment, the slope reduction angle β of the unpowered receiving section 51 is 18°-21°, preferably 20°; the slope reduction drop of the unpowered receiving section 51 is 600mm-800mm, preferably 700mm. Through the above arrangement, it can be ensured that the goods slide down smoothly and steadily. In this embodiment, there is an angle α between the roller 511 and the first direction to ensure that the goods are located in the center when sliding down along the unpowered receiving section 51 and will not collide with the side plate of the unpowered roller conveyor.

[0044] like Figure 3 As shown, the powered transmission section 52 includes a descending spiral turning machine 521 and a descending conveyor 522. One end of the descending spiral turning machine 521 is docked with the unpowered receiving section 51, and the other end of the descending spiral turning machine 521 is docked with one end of the descending conveyor 522. The other end of the descending conveyor 522 is docked with the lower output conveyor line 30. The initial speed of the descending spiral turning machine 521 matches the speed of the goods when they slide out of the unpowered receiving section 51, and the initial speed of the descending conveyor 522 matches the speed of the descending spiral turning machine 521 when the goods are output. This ensures that the goods are smoothly docked between the unpowered receiving section 51, the descending spiral turning machine 521 and the descending conveyor 522.

[0045] like Figure 7 As shown, the turning angle of the descending spiral turning machine 521 is 90°, so as to change the flow direction of the goods from being perpendicular to the input conveyor line 10 to being perpendicular to the lower output conveyor line 30, so that the goods can be smoothly conveyed to the lower output conveyor line 30. The descending slope height of the descending spiral turning machine 521 is 500mm-700mm, preferably 600mm. The speed range of the descending spiral turning machine 521 is 0.6-1.5m / s, and the speed is adjustable. The initial speed matches the speed when the goods slide out of the unpowered receiving section 51. The descending spiral turning machine 521 is a belt conveyor, and the descending spiral turning machine 521 is a prior art, and its specific structure will not be described here.

[0046] like Figure 8As shown, the slope angle γ of the slope-down conveyor 522 is 15°-18°, preferably 16°. The slope drop of the slope-down conveyor 522 is 900mm-1100mm, preferably 1000mm. The speed range of the slope-down conveyor 522 is 0.6-1.5m / s, and the speed is adjustable. The initial speed matches the speed of the slope-down spiral turning machine 521 when the goods are output. The slope-down conveyor 522 is a belt conveyor, and the slope-down conveyor 522 is a prior art, and its specific structure is not repeated here.

[0047] By setting the slope angle and slope drop of the unpowered roller conveyor, the slope-drop spiral turning machine 521 and the slope-drop conveyor 522, the total slope drop and the total slope angle can be divided into each section, so that each section is relatively flat, effectively avoiding the problem of goods rolling over during the sliding process and damage to the goods caused by the large impact force of the sliding.

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
