Description

Technical Field

[0001] The utility model relates to the field of sorting equipment, in particular to a narrow belt sorter and a sorting system. Background Art

[0002] The linear narrow belt sorter is a commonly used sorting equipment.

[0003] There are mainly two ways to drive the narrow belt trolley to run in a loop in the existing linear narrow belt sorter:

[0004] One is to drive by a linear motor. For example, the invention patent application with the application publication number of CN 117049107 A is this driving method.

[0005] The other is to drive by the cooperation of a chain and a sprocket. For example, the utility model patent with the authorization publication number of CN 218574305 U is this driving method.

[0006] In the structure driven by a linear motor, when the narrow belt trolley runs to the turning section, the impact is large, which easily causes the walking wheels to be damaged, and then the secondary plate impacts the linear motor, resulting in destructive damage.

[0007] When adopting the structure of the cooperation of a chain and a sprocket, due to the deficiency of chain drive, the layout length of the linear narrow belt sorter is limited, and the use requirements of multiple compartments cannot be met. Summary of the Utility Model

[0008] The purpose of the utility model is to solve the above problems existing in the prior art, and provide a narrow belt sorter and a sorting system.

[0009] The purpose of the utility model is realized by the following technical solutions:

[0010] A narrow belt sorter includes a basic component and a circle of narrow belt trolleys movably arranged on the track of the basic component. Adjacent narrow belt trolleys are connected by chains located at their two ends. Each chain is sleeved on two support sprockets, and the support sprockets are rotatably arranged on the basic component. A linear motor secondary component is arranged on part or all of the narrow belt trolleys, and a linear motor primary component corresponding to the linear motor secondary component is arranged on the basic component.

[0011] Preferably, the basic component includes two parallel lower straight rails and upper straight rails corresponding to the two lower straight rails respectively. The lower straight rails and the upper straight rails are connected by a frame, and the linear motor primary component is arranged above and / or below the frame.

[0012] Preferably, there are three frames arranged at equal intervals, and there are two linear motor primary components. One linear motor primary component is arranged on the tops of the two frames near one end of the narrow-band sorter, and the other linear motor primary component is arranged at the bottoms of the two frames near the other end of the narrow-band sorter.

[0013] Preferably, the linear motor primary component is connected to the frame through a height-adjusting component.

[0014] Preferably, the height-adjusting component is arranged on the frame so as to be adjustable in position along the sorting direction of the narrow-band trolley.

[0015] Preferably, a first brush is arranged at one end of the linear motor primary component close to the upstream.

[0016] Preferably, a protection component is arranged on the basic component upstream of each linear motor primary component.

[0017] Preferably, the protection component includes a mounting plate. A detection plate that can rotate around an axis extending parallel to the sorting direction of the narrow-band trolley and a detection sensor for detecting the position of the detection plate are arranged on the mounting plate. The detection plate is connected to an energy storage component that drives it to rotate and then reset.

[0018] Preferably, the protection component includes a second brush arranged upstream of the detection plate.

[0019] A sorting system includes the narrow-band sorter as described in any one of the above.

[0020] The advantages of the technical solution of the present utility model are mainly reflected in:

[0021] The narrow-band sorter of the present utility model is driven by a linear motor, which can effectively ensure the power requirements, so that the length of the narrow-band sorter can be flexibly adjusted to meet the use needs of multiple compartments. At the same time, the narrow-band trolleys are connected by a chain and the chain is sleeved on the support sprockets at the turning positions, which can effectively reduce the impact on the running wheels of the narrow-band trolleys when turning, effectively extend the service life of the running wheels, reduce the impact vibration in the turning section, and greatly reduce the risk of collision between the linear motor primary component and the secondary component.

[0022] The structure of the basic component of the present utility model can flexibly adjust the installation position and installation height of the linear motor primary component, which can greatly facilitate the realization of equipment assembly.

[0023] The present utility model arranges a first brush at the upstream end of the linear motor primary component, which can remove the sundries adsorbed by the linear motor secondary component to a certain extent, so as to protect the linear motor primary component.

[0024] The present utility model provides a protection component upstream of the primary component of the linear motor, which can promptly detect abnormal situations such as whether the secondary of the linear motor has dropped abnormally or adsorbed sundries, and stop the machine and give an alarm in case of abnormal situations, thus minimizing the risk of collision between the secondary component of the linear motor and the primary component of the linear motor. And a second brush is arranged upstream of the detection plate to minimize misjudgment caused by sundries adsorbed by the secondary component of the linear motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The narrow-band sorting machine disclosed by the present utility model will be described below with reference to the accompanying drawings, as shown in the attached Figure 1 - attached Figure 3As shown in the figure, it includes a basic component 100 and a circle of narrow belt trolleys 200 movably arranged on the track of the basic component 100. Adjacent narrow belt trolleys 200 are connected by chains 300 located at their two ends. Each of the chains 300 is sleeved on two support sprockets 400, and the support sprockets 400 are rotatably arranged on the basic component 100. A linear motor secondary component 210 is arranged on part or all of the narrow belt trolleys 200, and a linear motor primary component 500 corresponding to the linear motor secondary component 210 is arranged on the basic component 100.

[0033] As shown in the attached Figure 2 As shown in the figure, the basic component 100 includes an intermediate component 110 and end components 120 at both ends. The intermediate component 110 includes two parallel lower straight rails 111 and upper straight rails 112 corresponding to the two lower straight rails 111 respectively. The two ends of the lower straight rail 111 and the upper straight rail 112 corresponding thereto are respectively connected to the turning rails at the end components 120, so as to form a waist-shaped track for the narrow belt trolley 200 to move. The shapes of the lower straight rail 111 and the upper straight rail 112 can be designed according to needs. For example, in this embodiment, the upper straight rail 112 is in a stepped shape, and the lower straight rail 111 is generally in a shape like a "J". The structure of the end component 120 can be designed according to needs. For example, it can refer to the structure disclosed in the authorized announcement number CN217806946U, and the support sprockets 400 are arranged at the two end components 120.

[0034] As shown in the attached Figure 1 - attached Figure 3 As shown in the figure, the lower straight rail 111 and the upper straight rail 112 are connected by a frame 130, and the linear motor primary component 500 is arranged above and / or below the frame 130. Preferably, there are three frames 130 arranged at equal intervals along the extension direction of the lower straight rail 111, and there are two linear motor primary components 500. One linear motor primary component 500 is arranged on the tops of the two frames 130 near one end of the narrow belt sorter, and the other linear motor primary component 500 is arranged on the bottoms of the two frames 130 near the other end of the narrow belt sorter. And each frame 130 includes columns 131 at both ends, and the columns 131 are movably connected up and down to a fixed seat 132. The fixed seat 132 includes insertion holes corresponding to the columns 131. An operation hole 133 is opened on the side plate of the fixed seat 132, and a connection screw (not shown in the figure) corresponding to the operation hole is arranged on the bottom plate of the fixed seat 132. The adjusting screw passes through a through hole on the bottom plate of the column 131, and an adjusting nut (not shown in the figure) located below the column 131 is screwed on the connection screw.

[0035] As shown in the attached Figure 3As shown in the figure, the linear motor primary component 500 is connected to the frame 130 through a height adjustment component 600. The height adjustment component 600 is connected to both ends close to the linear motor primary component 500. The height adjustment component 600 includes a U-shaped connecting plate 610. The connecting plate 610 is fixed on the frame 130. A height adjustment bolt 620 is vertically arranged on the horizontal bending plate of the connecting plate 610. The height adjustment bolt 620 is connected to the side plate of the linear motor primary component 500. The height adjustment bolt 620 is fixed to the side plate through a height adjustment nut 630 and a fastening nut 640.

[0036] As shown in the attached Figure 3 figure, the height adjustment component 600 is arranged on the frame 130 in a position-adjustable manner along the sorting direction of the narrow belt trolley 200. Specifically, the frame 130 includes an upper connecting beam 133 and a lower connecting beam 134 that are vertically distributed between the upper straight rail 112 and the lower straight rail 111. Strip-shaped holes 135 or strip-shaped grooves extending along their extension directions are provided at the top and both sides of the upper connecting beam 133 and the lower connecting beam 134. Preferably, two rows of the strip-shaped holes 135 are respectively provided on both sides of the upper connecting beam 133 and the lower connecting beam 134. Connecting holes matching the height of the two rows of strip-shaped holes 135 are provided on the two vertical plates of the connecting plate 610 of the height adjustment component 600. Thus, the connecting plate 610 and the frame 130 can be connected through bolts and nuts passing through the connecting holes and the strip-shaped holes 135, and the position adjustment of the height adjustment component 600 can be achieved by adjusting the position of the bolts in the strip-shaped holes 135 or the strip-shaped holes where the bolts are located.

[0037] As shown in the attached Figure 1 figure, in order to prevent metal debris and the like adsorbed on the linear motor secondary component 210 from colliding when the metal debris moves towards the linear motor primary component 500, a first brush 510 is provided at one end of the linear motor primary component 500 close to the upstream. The upstream refers to the position that the narrow belt trolley 200 passes through first during the movement process. The bristles of the first brush 510 protrude above or below the top of the linear motor primary component 500. Specifically, when the linear motor primary component 500 is arranged above the frame 130, the bristles of the first brush 510 protrude above the top of the linear motor primary component 500 and are slightly higher than the bottom of the linear motor secondary component of the narrow belt trolley at the upper straight rail. On the contrary, when the linear motor primary component 500 is arranged at the bottom of the lower connecting beam 134 of the frame 130, the bristles of the first brush 510 protrude below the linear motor primary component 500 and are slightly lower than the top of the linear motor secondary component of the narrow belt trolley at the lower straight rail.

[0038] As shown in the attached Figure 1As shown, a protection component 700 is provided on the base component 100 upstream of each linear motor primary component 500, and the protection component 700 is arranged on a frame.

[0039] As shown in the attached Figure 4 , the attached Figure 5 As shown, the protection component 700 includes a mounting plate 710. A detection plate 720 that can rotate about an axis extending parallel to the sorting direction of the narrow-band trolley 200 and a detection sensor 730 for detecting the position of the detection plate 720 are provided on the mounting plate 710. The detection plate 720 is connected to an energy storage member 740 that drives it to rotate and then reset. The top of the detection plate 720 is located at the gap between the linear motor primary component 500 and the linear motor secondary component 210. When there are sundries adsorbed on the surface of the linear motor secondary component 210 or the linear motor secondary component 210 sags, when the linear motor secondary component 210 moves to the detection plate 720, it drives the detection plate 720 to rotate, and the detection sensor 730 switches from being able to detect the detection plate 720 to being unable to detect the detection plate 720 or from being unable to detect the detection plate 720 to being able to detect the detection plate 720. Thus, it is possible to determine whether there is an abnormal situation based on the signal of the detection sensor 730, and when an abnormality is detected, the sorting loop formed by the narrow-band trolley 200 can be controlled to stop running and an alarm can be issued.

[0040] Specifically, the mounting plate 710 is fixed on a frame 130. It includes a U-shaped groove plate. A hinge block is provided on one side of the detection plate 720 facing the U-shaped groove plate. The hinge block is connected to the U-shaped groove plate through a rotating shaft 760. Under normal conditions, the detection plate 720 maintains a vertical state. The detection sensor 730 can be a known proximity sensor, which is arranged on the side of the detection plate 720 facing away from the U-shaped groove plate. Under normal conditions, the proximity sensor can detect the detection plate 720. The energy storage member 740 is also connected to the lower part of the side of the detection plate 720 facing away from the U-shaped groove plate. The energy storage member 740 is a tension spring, and the other end of the tension spring is fixed on the mounting plate 710. At the same time, at least one limiting rod 750 abuts against the side of the detection plate 720 facing the U-shaped groove plate. The limiting rod 750 is fixed on the U-shaped groove plate, and the limiting rod 750 cooperates with the energy storage member 740 to keep the detection plate 720 in a vertical state.

[0041] As shown in the attached Figure 4 , the attached Figure 5 As shown, the protection component 700 includes a second brush 770 provided upstream of the detection plate 720, and the installation height of the second brush 770 matches the installation height of the first brush 510.
