In order to minimize the risk of the sorting carriages coming into contact with the infeed conveyor 2, the small rollers 25 are at a height comparable to the bottom of the large rollers 24 when the first conveying section 221 is parallel to the horizontal plane (the output end of the infeed conveyor 2 is at the lowest level). At this time, the lower portion 281 of the conveyor belt 28 has a small gap with the sorting cell of the upper straight and turning sections, and thus, the contact is easily made, and at the same time, the tightness of the conveyor belt 28 needs to be adjusted.

As shown in fig. 4, a tension roller 220 is further disposed between the two risers 232, the tension roller 220 is located below the direction-changing rollers 26 and is attached to the bottom surface of the lower portion 281 of the conveyor belt, and the lower portion 281 is in an upwardly convex state, and when the output end of the introducing conveyor 2 is at the lowest position, the bottom of the tension roller 220 is not lower than the bottoms of the small and large rollers.

The shaft 3 is provided on the holder 6 so as to be rotatable with respect to the holder 6, and in this case, the shaft 3 is fixed to the bottom or the side of the introducing conveyor 2. Or, the shaft 3 is fixed on the bracket 6 and cannot rotate relative to the bracket 6, at this time, the introducing conveyor 2 is pivoted with the shaft 3, the shaft 3 is connected with bearing seats 250 at the bottom of the introducing conveyor 2 through bearings 7 at two ends of the shaft 3, and the bearing seats 250 are fixed at the bottoms of the two profiles 231. Of course, the shaft 3 may be a single shaft body, or may be two coaxial shaft bodies.

In the above embodiment, the output end of the introducing conveyor 2 has a problem of being tilted up due to the gravity of the heavy object, and therefore, in a more preferable structure, as shown in fig. 2, the introducing conveyor 2 is kept in a normal state by the floating mechanism 4, and in the normal state, the first conveying section is parallel or approximately parallel to the horizontal plane. Of course, the first conveying section may be in other inclined states.

When both sides of the introducing conveyor 2 protrude out of both sides of the vertical sorting machine, the floating mechanism 4 may be provided at the bottom or side of the introducing conveyor 2, and in this case, the floating mechanism 4 may be provided on a support structure at the outside of the vertical sorting machine or on a side frame 121 of the vertical sorting machine.

The spring 43 is located below the mounting part 42, the upper end of the spring 43 is fixed, and is specifically connected to the bottom of the mounting part 42, the lower end of the spring 43 is connected to the blocking part 44 at the lower end of the connecting shaft, and when the lower section of the connecting shaft 41 is provided with threads, the blocking part 44 can be a nut coaxially connected below the connecting shaft 41; thus, the spring 43 applies a pulling force to the support 234, keeping it in the low position.

Alternatively, the spring 43 is located above the mounting member 42, and has a lower end fixed in position and an upper end connected to the connecting member 44 at the upper end of the connecting shaft 41, so that the spring 43 also applies a tensile force to the supporting member 234.

Alternatively, the spring 43 is positioned above the mounting member 42, has its lower end connected to the mounting member and its upper end fixed, and thus presses the support member 234.

Of course, in another embodiment, the universal joint or the ball joint 5 may be the structure of the floating mechanism, and in this case, the floating mechanism is pivotally connected to the supporting member, i.e. the floating mechanism is rotatable relative to the supporting member.

As shown in fig. 7, a limiting plate 45 is further disposed on the connecting shaft, the limiting plate 45 is disposed coaxially on the connecting shaft and above the mounting member 42, and in a normal state, the spring 43 makes the limiting plate 45 abut against the mounting member to limit the lowest position of the supporting member 234, and at this time, the supporting member 234 may contact with the top surface of the side frame 121 and may also maintain a certain distance, preferably, the supporting member 234 maintains a certain distance from the side frame 121.

In view of the fact that after the outer end of the introducing conveyor 2 rotates due to the abnormal operation of the equipment, the equipment is preferably checked after the shutdown to discharge the abnormal condition, the sorting apparatus further includes a control device (not shown in the figure), which may be any known control system, and is not described herein for the sake of brevity. The control device is connected with a detection mechanism 9 and at least controls the vertical sorting machine 1 to stop according to a detection signal of the detection mechanism 9, and the detection mechanism 9 is used for detecting the rotation action of the guide-in conveyor.

One of the sensor 91 and the trigger 92 is fixed in position, and the other is provided on the introducing conveyor. For example, the sensor 91 is fixed to the top surface of the side frame 121, and the trigger 92 is fixed to the support member 234. When the import conveyor 2 is in a normal state, the sensor 91 can sense the supporting piece 234, and when the output end of the import conveyor 2 is tilted upwards until the sensor 91 cannot sense the supporting piece 234, the signal of the sensor 91 is sent to the control device, and the control device controls the vertical sorting machine 1 to stop working. Of course, in another embodiment, the sensor 91 cannot sense the trigger 13 when the introducing conveyor 2 is in a normal state, and when the introducing conveyor 2 rotates until the trigger 13 triggers the sensor 91, a signal of the sensor 91 is sent to a control device to control the vertical sorting machine 1 to stop.

Of course, the triggering element or sensor can also be arranged at another location, for example, they can be arranged at the input of the insertion conveyor 2, or the sensor 91 can also be fixed to the insertion conveyor, the triggering element being fixed in position.

In another embodiment, the sensor may not be matched with the trigger, and the detecting mechanism may be a distance measuring sensor, such as a distance measuring device like a laser distance meter, which detects the distance between the distance measuring sensor and the introducing conveyor to determine whether the introducing conveyor has abnormal rotation, and the distance measuring sensor may be arranged at any feasible position above or below the introducing conveyor.

Example 2
