[0031] The objects, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention, and any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

They are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0033] Example 1

[0034] The following describes the material jam detection device disclosed by the present invention in conjunction with the accompanying drawings. The material jam detection device is used in a linear narrow belt sorting system or a vertical cross belt sorting system. Figure 1 As shown, it includes a mounting frame, and also includes a detection rod 1, a stuck material signal trigger 2, a rotating shaft 3, an elastic component, and a detection sensor 4. The detection rod 1 is connected to two stuck material signal triggers 2, and each of the stuck material signal triggers 2 can rotate around the rotating shaft 3 set on the mounting frame and / or can move linearly relative to the rotating shaft 3 in a direction perpendicular to the axial direction of the rotating shaft 3. The elastic component maintains the stuck material signal trigger 2 in the first position, and at least one detection sensor 4 is set on the mounting frame to monitor whether the stuck material signal trigger 2 is maintained in the first position.

[0035] When testing after the mounting bracket is fixed in position, if pressure is applied to the top of the detection rod 1, the two material jam signal triggering members 2 will rotate about the rotating shaft 3 and / or slide downward along the rotating shaft 3. At this time, the detection sensor 4 can detect the position change of the abnormal triggering members, thereby detecting the material jam. When the material jam is resolved, the elastic component causes the material jam signal triggering members 2 to return to the first position, at which point the detection sensor 4 can emit a normal signal.

[0036] As attached Figure 1 As shown, the mounting frame includes two separate end plates 5. Of course, in other embodiments, the two end plates 5 can also be connected by a connecting structure. A rotating shaft 3 is mounted on each of the end plates 5. The rotating shaft 3 is a short shaft and is connected to the end plates 5 by means of screws or other means. The two rotating shafts 3 are coaxial. Of course, in other embodiments, the two rotating shafts 3 can also be a long shaft that connects the two end plates 5.

[0037] As attached Figure 1 -Attached Figure 3As shown, each of the rotating shafts 3 is connected to a material jamming signal trigger 2, and the material jamming signal trigger 2 includes a rod end joint bearing 21 and a movable arm 22. The inner ring of the rod end joint bearing 21 is connected to the end of the detection rod 1, and the screw of the rod end joint bearing 21 is connected to the movable arm 22. The movable arm 22 is connected to the rotating shaft 3, and the movable arm 22 is a long strip as a whole. A connecting portion 23 is formed at the upper end of the movable arm 22, and a screw hole for connecting the screw is formed at the connecting portion 23. A monitoring protrusion 24 is formed at the lower end of the movable arm 22, and a notch 25 is formed above the monitoring protrusion 24. When the material jamming signal trigger 2 is in the first position, the detection sensor 4 detects the monitoring protrusion 24 of the material jamming signal trigger 2. At this time, it can be determined that no material jam has occurred. When the monitoring protrusion of the movable arm 22 moves downward and / or rotates around the rotating shaft 3 in the direction away from the detection sensor 4, the detection sensor 4 is opposite to the notch 25 and cannot detect the monitoring protrusion. At this time, it is determined that a material jam has occurred. The detection sensor 4 can be a proximity sensor or a distance measuring device, which is also fixed on the inner side of the end plate.

[0038] As attached Figure 2 , Attachment Figure 3 As shown, in order to facilitate the connection between the movable arm 22 and the rotating shaft 3 and enable the movable arm 22 to rotate and slide at the same time, a waist-shaped hole 26 for mounting the rotating shaft 3 is formed on the movable arm 22. The waist-shaped hole 26 is located in the middle and upper position of the movable arm 22. The width of the waist-shaped hole 26 is equivalent to the outer diameter of the rotating shaft 3 or the roller 31 on the rotating shaft 3. At the same time, the length extension direction of the waist-shaped hole 26 is parallel to the axial direction of the screw, that is, the linear movement direction of the movable arm is the up and down direction.

[0039] As attached Figure 2 , Attachment Figure 3 As shown, the rotating shaft 3 is a bolt, which is screwed into the screw hole on the end plate 5. More preferably, a roller 31 is provided on the rotating shaft 3, for example, it can be a bearing, and the roller 31 is located in the waist-shaped hole 26, so that the rotation and sliding movement of the movable arm 22 can be converted into rolling movement to effectively reduce the wear of parts. At the same time, a limiting end plate 32 is screwed on the rotating shaft 3, and the movable arm 22 is limited between the limiting end plate 32 and the end plate 5.

[0040] As attached Figure 2As shown, a first connecting member 6 is provided on the movable arm 22, and the first connecting member 6 and the detection rod 1 are located on both sides of the rotating shaft 3. Specifically, the detection rod 1 is located above the rotating shaft 3, and the first connecting member 6 is located below the rotating shaft 3 and is directly opposite to the rotating shaft 3. The first connecting member 6 is also preferably a bolt, and the bolt is screwed onto the end plate 5.

[0041] As attached Figure 2 As shown, when the movable arm 22 can only move linearly along the rotating shaft 3, the elastic component includes a first spring 8 connected between the first connecting member 6 and the rotating shaft 3; and, under normal circumstances, the first spring 8 causes the rotating shaft 3 to be located at the lower end of the waist-shaped hole 26.

[0042] As attached Figure 2 As shown, when the movable arm 22 can only rotate around the rotating shaft 3, the elastic component includes a second spring 9, one end of the second spring 9 is connected to the first connecting member 6, and the other end of the second spring 9 is connected to a second connecting member 7, and the second spring 9 and the detection sensor 4 are located on the same side of the jam signal trigger 2.

[0043] As attached Figure 2 As shown, to facilitate connection with the conveyor, the two end plates 5 are formed with L-shaped protrusions 51 on their opposing end surfaces. This facilitates quick positioning of the end plates 5 when subsequently connected to other equipment. The rotating shaft 3, first connecting member 6, and second connecting member 7 are all disposed on the protrusions 51. The protrusions 51 increase the thickness of the end plates 5, thereby providing better support for the rotating shaft 3, first connecting member 6, and second connecting member 7. External connection holes 52 are formed on the portion of the end plates 5 located outside the protrusions 51. These external connection holes 52 are multiple, horizontally extending, waist-shaped connection holes.

[0044] Example 2

[0045] This embodiment discloses a conveyor, as shown in the attached Figure 4As shown, the card detection device 10 of the above embodiment is included. The conveyor can be a belt conveyor or a roller conveyor and other known conveying equipment, the card detection device 10 is arranged at the input end of the conveyor, and the top of the end plate 5 of the card detection device 10 and the vertex of the detection rod 1 are lower than the conveying surface of the conveyor, and the waist-shaped connecting hole formed on the end plate 5 can be connected with the end of the rack 20 of the conveyor, so that the two end plates 5 are detachably and adjustably connected with the rack of the conveyor, which facilitates the installation position debugging of the card detection device. The two side connecting plates of the rack 20 are connected with the two end plates 5 of the card detection device, and each side connecting plate has a right angle surface matched with the L-shaped convex part 51 on the inner side of the end plate 5. When assembled, the right angle surface of the side connecting plate can abut against the L-shaped surface of the convex part 51, so that the positioning of the end plate and the side connecting plate of the rack 20 can be quickly realized.

[0047] The present embodiment discloses a sorting device, at this time, the sorting device can directly adopt a linear narrow belt sorting machine or a vertical cross belt sorting machine, and the card detection device can be directly arranged at the turning position of one end of the linear narrow belt sorting machine or the vertical cross belt sorting machine, that is, in the present embodiment, the card detection device is assembled with the sorting device as a whole.

[0048] Of course, in another embodiment, as shown in the accompanying drawings, Figure 5 As shown, the sorting device includes the conveyor of the above embodiment 2 and a linear narrow belt sorting machine or a vertical cross belt sorting machine, and the conveyor is located at the turning position of one end of the linear narrow belt sorting machine or the vertical cross belt sorting machine, and the goods are conveyed to the conveyor by the linear narrow belt sorting machine or the vertical cross belt sorting machine. The conveying surface of the conveyor is lower than the conveying surface of the linear narrow belt sorting machine or the vertical cross belt sorting machine, and the card detection device 10 is located between the rack of the conveyor and the linear narrow belt sorting machine or the vertical cross belt sorting machine.

[0049] The linear narrow belt sorting machine can be the structure disclosed in the application No. 202210085573.3; the vertical cross belt sorting machine can be the structure disclosed in the application No. 202021761807.4.

[0050] In the present embodiment, the linear narrow belt sorting machine is used in cooperation with the conveyor. At the same time, in the present embodiment, the single narrow belt conveyor of the linear narrow belt sorting machine is improved.

[0051] As shown in the accompanying drawings, Figure 6As shown, the narrow belt conveyor of the present invention includes a frame 100, on which a conveying assembly 200 is provided, and a buffer bar 300 is provided on at least one side of the frame 100, wherein the buffer bar 300 is located at the top position of the side of the frame 100 and protrudes from the side of the frame 100, and the buffer bar 300 extends along the conveying direction of the conveying assembly 200 and the two ends of the buffer bar 300 are adjacent to the two ends of the frame 100.

[0052] As attached Figure 6 , Attachment Figure 7 As shown, in order to make the frame 100 as lightweight as possible and easy to assemble, the frame 100 includes a main frame 110 and roller mounting blocks 120 screwed to both ends of the main frame 110, and the main frame 110 includes a top plate 111 and side plates 112 located on both sides of the top plate 111, so that the main frame 110 is approximately U-shaped as a whole.

[0053] The roller mounting block 120 can be connected to the main frame 110 by screwing or welding.

[0054] As attached Figure 7 As shown, to facilitate installation of the roller mounting block 120, two straight connecting slots 113 extending to the ends of the side panels 112 are formed on each of the two side panels 112 of the main frame. To install the roller mounting block 120, a nut (not shown) is placed in the connecting slot 113. The connecting holes on the roller mounting block 120 are aligned with the screw holes on the nut in the connecting slot 113, and a bolt is passed through the connecting hole and screwed into the nut to secure the connection. Of course, the connecting slot 113 also facilitates the installation of other structures, such as busbars and drive card assemblies.

[0055] As attached Figure 6 , Attachment Figure 8 As shown, the conveying assembly 200 is a belt conveying assembly, which includes two rollers 210 and a belt 220 mounted on the two rollers 210. One of the two rollers 210 is an electric roller, and the two rollers 210 are respectively arranged on the roller mounting blocks 120 at both ends. The diameter of the roller 210 is greater than the height of the main frame.

[0056] As attached Figure 7 , Attachment Figure 8As shown, a belt limiting groove 114 for the belt 220 to be embedded in is formed on the top surface of the top plate 111 of the main frame. The depth of the belt limiting groove 114 is less than the thickness of the belt 220, and its width is equivalent to the width of the belt 220. Therefore, when the belt 220 rotates, it can prevent the belt 220 from running off the track and reduce the thickness of the portion of the belt 220 protruding from the upper surface of the main frame, which is beneficial to reducing the risk of damage caused by contact between the belt 220 and the goods when the sorting device is stuck at the tail and when the goods fall from the end of the sorting device.

[0057] As attached Figure 7 , Attachment Figure 8 As shown, similar to the conventional anti-deviation structure of the belt 220 , a guide bar 221 is formed on the inner side of the belt 220 , and a guide bar groove 115 matching the guide bar 221 is formed in the limiting groove.

[0058] As attached Figure 6 As shown, in order to facilitate the tensioning of the belt 220, waist-shaped mounting holes 121 for mounting the roller 210 are formed on the two roller mounting blocks 120 located at the same end of the main frame 110, and the roller installed at the waist-shaped mounting hole 121 is not an electric roller. The waist-shaped mounting hole 121 extends along the conveying direction of the conveying assembly 200, and the waist-shaped mounting hole 121 is connected to an adjusting screw hole 122. The adjusting screw hole 122 is parallel to the extension direction of the waist-shaped mounting hole 121 and extends to the outer end of the roller mounting block 120. An adjusting bolt 230 is screwed into the adjusting screw hole 122 and connected to one end of the support shaft 211 of the roller 210. By rotating the adjusting bolt 230 to adjust its position in the adjusting screw hole 122, the support shaft 211 connected thereto can be synchronously driven to move to adjust its position, thereby achieving tensioning of the belt 220. Such a structure can achieve tensioning of the belt 220 at the end of the narrow belt conveyor, which is more convenient for belt tensioning operation after the sorting equipment is assembled in place.

[0059] As attached Figure 8As shown, the frame 100 is provided with the buffer strip 300 on both sides. By providing the buffer strip 300 on both sides of the frame 100, when an article falls from above by the end, the buffer strip 300 can effectively protect the narrow belt conveyor below the falling article, reduce the impact on the upper side of the narrow belt conveyor at the turning, at the same time, the buffer strip 300 can reduce the damage of the goods, and can provide a certain reaction force to the goods, reduce the probability of material jamming, and reduce the risk of equipment and goods damage. In addition, when the sorting equipment end appears material jamming, the lower side of the narrow belt conveyor at the turning is most likely to contact the jammed goods, thereby reducing the damage of the narrow belt conveyor. Further, when the narrow belt conveyor runs in a straight line, the buffer strip 300 can effectively close the space between the narrow belt conveyors, avoid dust, sundries and other things from entering the inside of the sorting equipment to affect the stable use of the equipment, and avoid hard contact between the narrow belt conveyors, reduce the running noise.

[0060] The buffer strip 300 can adopt various feasible soft materials, for example, rubber strips, silica gel strips, soft plastics, etc. The buffer strip 300 is a rubber strip. The buffer strip 300 can be connected with the frame 100 in a known feasible manner, for example, by using a glue sticking manner or a screw fixing manner. Preferably, the buffer strip 300 is clamped on the frame 100.

[0061] As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. Figure 7 , as shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. Figure 9 As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. The buffer strip 300 includes an embedded part 310 and a buffer part 320. When installing, the tip of the embedded part 310 is directed to the entrance part 131 and inserted into the clamping part 132, so that the arrow part of the embedded part 310 is clamped at the clamping part 132.

[0062] As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. Figure 8 , as shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. Figure 9 As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides. The buffer part 320 of the buffer strip 300 protruding outside the frame 100 is hollow, that is, the buffer part 320 is a hollow pipe, and the embedded part 310 is also hollow. Such a structure can reduce the installation difficulty when the buffer strip 300 is installed into the clamping groove 130 by deforming the buffer strip 300 itself, and can better deform and buffer when a collision occurs subsequently.

[0063] As shown in FIG. 1 and FIG. 2, the frame 100 is provided with the buffer strip 300 on both sides.Figure 6 As shown, walking wheels 400 and limiting wheels 500 are respectively arranged at both ends of the frame, and the rollers and the limiting wheels are arranged to roll on the track, so that the narrow belt conveyor can move more smoothly when rotating and the position of the narrow belt conveyor on the track is limited. The ends of the frame are also connected with chains, so that the narrow belt conveyor can be driven to rotate by a chain driving mechanism.
