Referring to fig. 1, fig. 1 is a schematic structural diagram of a sorting trolley driven by a linear motor in the prior art. As shown in fig. 1, a sorting trolley 1 is provided to a transfer rail 5 in the prior art. The lower end of the sorting trolley 1 is connected with a secondary plate 2. A plurality of linear motors 3 are provided at intervals throughout the lower end of the transfer rail 5. The linear motor 3 comprises an air gap (not shown in the figure), when the secondary plate 2 passes through the air gap, the linear motor 3 generates acting force on the secondary plate 2, so that the secondary plate 2 drives the sorting trolley 1 to move along the conveying track 5.

Generally, in order to improve the operation efficiency of the linear motor 3, the width of the secondary plate 2 is similar to the width of the air gap.

It is understood that when the secondary plate 2 is used over a period of time, a situation of deformation easily occurs. Therefore, the secondary plate 2 often scratches and scratches the linear motor 3, and the linear motor 3 is damaged.

To this end, some embodiments of the present disclosure provide a monitoring device of a secondary board. The following description will be made with reference to fig. 2. Fig. 2 is a schematic structural diagram of one embodiment of a monitoring device of a secondary board according to the present disclosure. As shown in fig. 2, the monitoring device comprises a base 4, a displacement mechanism 6 and a monitoring assembly (not shown in the figure). The base 4 is used to carry the displacement mechanism 6 and the monitoring assembly. The base 4 is connected to the inner side of the transfer rail 5.

In some embodiments, the base 4 may be attached to the inside of the transfer rail 5 in a variety of ways. For example, the monitoring device may be adjustably connected to the conveying rail 5 by means of bolts, screws, etc., so that the relative position of the monitoring device and the conveying rail 5 can be determined and firmly connected. And then for monitoring secondary plate 2 provides the guarantee, improve the monitoring precision.

Alternatively, the base 4 may be disposed in front of the linear motor 3 so that the secondary plate 2 may pass through the monitoring device first. The function of protecting the linear motor 3 is achieved.

In some alternative implementations of some embodiments, a jaw assembly may be provided to connect the base and the transfer rail. The following description will be made with reference to fig. 3. Fig. 3 is a schematic structural diagram of another embodiment of a monitoring device of a secondary board according to the present disclosure. As shown in fig. 3, the jaw assembly includes a connecting plate 71, a jaw 72, and an adjusting member 73. One end of the connecting plate 71 is fixedly connected to the base 4. The other end of the connecting plate 71 extends towards the conveyor track 5. One end of the claw 72 is connected to the connecting plate 71. The other end of the catch 72 is hook-shaped and snaps to the inner edge of the conveyor track 5. One end of the adjusting member 73 is connected to the connecting plate 71. The other end of the adjustment member 73 adjustably abuts against the outer edge of the conveying track 5. During the mounting process, the above-mentioned claws 72 may be first snapped to the inner edge of the conveying rail 5, and then the claws 72 are tightly and firmly engaged with the inner edge of the conveying rail 5 by adjusting the adjusting members 73. In this way, the connection of the base 4 to the conveyor track 5 is achieved by the jaws 72 and the adjustment members 73 at two points of action inside and outside the conveyor track 5. Therefore, the stability of the monitoring device can be improved when the sorting trolley 1 passes through the monitoring equipment. The monitoring device is prevented from shaking to cause errors of monitoring results. Alternatively, the jaws 72 may be provided as length-adjustable members. Thus, by adjusting the length of the claw 72, the position of the base 4 relative to the conveying rail 5 and the secondary plate 2 can be adjusted, and the flexibility of the monitoring device is improved.

It should be noted that fig. 3 illustrates four jaw assemblies as an example, but this is not exclusive, and the number of jaw assemblies may be plural. The number of jaw assemblies can be adjusted by those skilled in the art according to the actual situation. Such variations are not beyond the scope of the present disclosure.

The displacement mechanism of the present disclosure is provided to the base, which may include an adjustable monitoring gap. Alternatively, the monitoring gap may be set to a width that is adapted to the width of the secondary plate or the linear motor air gap in the initial state. When the secondary plate is deformed, the secondary plate acts on the monitoring gap when passing through the monitoring gap. Thereby causing the monitoring gap to change. And then gather the width in this monitoring clearance through the monitoring subassembly, alright acquire the deflection of this secondary plate. Therefore, the deformation of the secondary plate can be obtained under the condition that the work of the sorting trolley is not influenced. And further, the working efficiency of the sorting trolley is ensured, and the monitoring work can be completed on the deformation of the dynamic secondary plate.

As an example, the displacement mechanism may comprise two spaced apart stops. The stop is slidably coupled to the displacement mechanism. The above-described monitoring gap may be formed between the stoppers. While a return member, such as a spring, is provided between the two stops. Therefore, when the deformed secondary plate passes through the monitoring gap, the deformed secondary plate can act on the two stop blocks, so that the monitoring gap between the two stop blocks is changed. After the deformed secondary plate passes, the two stoppers are restored to the original positions by the restoring member. Ready for the next monitoring.

The monitoring assembly can be arranged inside one of the two stop blocks, so that the distance between the two stop blocks is monitored, and the deformation amount of the secondary plate is obtained. The monitoring component may be a variety of ranging sensors including, but not limited to, laser ranging sensors, infrared ranging sensors, and the like.

Some alternative implementations of some embodiments of the displacement mechanism are described next in connection with fig. 4. FIG. 4 is a schematic structural diagram of one embodiment of a displacement mechanism according to the present disclosure. As shown in fig. 4, the displacement mechanism includes a first stop assembly (not shown) and a second stop assembly (not shown). The first stop block assembly and the second stop block assembly are arranged at intervals to form the monitoring gap, and the first stop block assembly and the second stop block assembly can be slidably arranged on the base.

The first stopper assembly includes a first slider 63 and a first roller 61, and the first roller 61 is vertically and rotatably coupled to the first slider 63. The first roller 61 is rotatable about a vertical axis. The first slider 63 is slidably connected to the base 4 in a direction toward or away from the transfer rail 5. A rail may be provided on the base 4 for the first slider 63 to slide. The spacing between the first roller 61 and the second roller 62 forms a monitoring gap.

The second stopper assembly includes a second slider 64 and a second roller 62, and the second roller 62 is vertically and rotatably connected to the second slider 64. The second roller 62 is rotatable about a vertical axis. The second slider 64 is slidably connected to the base 4 in a direction toward or away from the transfer rail 5. As an example, a rail may be provided on the base 4 for the second slider to slide.

By providing the first roller 61 and the second roller 62, when the deformed secondary plate 2 (shown in fig. 3) passes through the monitoring gap, after the secondary plate 2 acts on the first roller 61 and the second roller 62, the friction force between the secondary plate 2 and the first roller 61 and the second roller 62 is reduced by the rotation of the first roller 61 and the second roller 62, and the monitoring precision is prevented from being influenced by the vibration caused by the excessive friction force. The first roller 61 and the second roller 62 may be made of rubber, so as to further reduce friction.

A plurality of rolling balls may be provided inside the first slider 63 and the second slider 64, and a function of reducing friction force may be achieved instead of the first roller 61 and the second roller 62.

With continued reference to fig. 4, the displacement mechanism may further include a first return member 65 and a second return member 66. The first return member 65 connects the first slider 63 and a first end (upper end in the drawing) of the base 5. A first baffle 67 may be provided at a first end of the base 4, the first return member 65 being connected to the first baffle 67. The first return member 65 is for applying a force to the first slider 63 toward the middle of the base 4.

The second return member 66 connects the second slider 64 to a second end (lower end as viewed in the figures) of the base plate 4, a second stop plate 68 may be provided at the second end of the base plate 4, and the second return member 66 is connected to the second stop plate 68. The first restoring member 65 and the second restoring member 66 are used for applying a force to the second slider 64 toward the middle of the base 4. As an example, the first and second return members 65 and 66 may be springs, cylinders, or the like.

In this way, after the deformed secondary plate passes through the displacement mechanism, the first slider 63 and the second slider 64, which are acted upon, can be restored to the original positions by the first restoring member 65 and the second restoring member 66.

Optionally, a limit member 69 may be further disposed between the first slider 63 and the second slider 64. The width of the limit member 69 is set so that the monitoring gap formed by the first roller 61 and the second roller 62 is adapted to the width of the air gap or the secondary plate 2 when the first slider 63 and the second slider 64 are in the rest state. Therefore, after the first sliding block 63 and the second sliding block 64 are displaced, the first restoring member 65 and the second restoring member 66 can restore to the initial position under the action of the limiting member 69, and the monitoring gap in the static state is ensured not to be changed. And then can reduce monitoring error, improve monitoring accuracy.

Referring next to fig. 5 with continued reference to fig. 4, fig. 5 is a schematic structural diagram of an embodiment of a monitoring assembly according to the present disclosure. As shown in fig. 4 and 5, the monitoring assembly may include a plurality of monitoring modules 8. The monitoring module 8 is provided to the first and second shutters 67 and 68 so that the amount of deformation of the secondary plate can be determined by monitoring the distance between the first shutter 67 and the first slider 63 and the distance between the second shutter 68 and the second slider 64. As an example, the monitoring module may be a ranging sensor.

The monitoring module 8 may also be disposed between the first restoring member 65 and the first baffle 67 and between the second restoring member 66 and the second baffle 68. The monitoring module determines the displacements of the first and second slides 63, 64 by acquiring the forces generated by the secondary plate 2 when it passes through the displacement mechanism, and the damping coefficients of the first and second return members 65, 66.

It should be noted that, although fig. 4 illustrates the monitoring device including two displacement mechanisms, this is not exclusive, and those skilled in the art can adjust the number of displacement mechanisms according to actual situations.

The above embodiments of the present disclosure have the following advantages: monitoring accuracy may be improved by the monitoring device of the secondary board of some embodiments of the present disclosure. Specifically, the reason for the decrease in monitoring accuracy is: the secondary plate and the displacement mechanism in operation generate vibration caused by friction, the accuracy of data acquisition of the monitoring assembly is easily influenced, and the monitoring precision is also influenced by the change of the initial monitoring clearance. Based on this, the monitoring devices of the secondary plate of some embodiments of the present disclosure include a first roller and a second roller, when the deformed secondary plate passes through the monitoring gap, after the secondary plate acts on the first roller and the second roller, through the rotation of the first roller and the second roller, the friction force between the secondary plate and the secondary plate is reduced, and the influence of the vibration caused by the excessive friction force on the monitoring precision is avoided. The monitoring device of the secondary plate of some embodiments of the present disclosure further includes a first return member, a second return member, and a stop member. The width of the limiting component is set to enable the monitoring gap formed by the first sliding block and the second sliding block to be matched with the width of the air gap or the secondary plate in a standing state. In addition, after the first sliding block and the second sliding block are displaced, the first sliding block and the second sliding block can be restored to the initial positions under the action of the first restoring member and the second restoring member and the limitation of the limiting member, and the monitoring gap in the static state is ensured not to be changed. And then can reduce monitoring error, improve monitoring accuracy.

Some embodiments of the present disclosure also provide a monitoring system of a secondary board. The system includes a controller and a monitoring device of the secondary board. The monitoring device of the secondary board is the monitoring device of the secondary board of each embodiment. The controller is in communication connection with a monitoring component of a monitoring device of the secondary board. The operation of the monitoring system will be described with reference to fig. 6. Fig. 6 is a schematic flow 600 of the operation of a monitoring system of a secondary board according to the present disclosure. The workflow of the monitoring system comprises the following steps:

and 601, the controller is in communication connection with the monitoring assembly, and the monitoring assembly acquires width information of the monitoring gap and transmits the width information to the controller.

In some embodiments, the controllers may be connected by various connections, such as wire, wireless communication links, or fiber optic cables, among others. The monitoring component can be a sensor with information transmission function. The Controller may be a processor, a system, or the like having a data processing function, for example, a Programmable Logic Controller (PLC) system. The person skilled in the art can make the selection on the basis of common general knowledge.

And step 602, the controller responds to the fact that the numerical value represented by the width information exceeds a preset threshold value, and the controller determines the deformed secondary plate according to the running speed of the secondary plate and the acquisition time of the monitoring assembly.

In some embodiments, first, a notch may be provided in the secondary plate of any sorting cart, which is determined to be the first cart by the sensors.

Next, the controller may filter the width information collected by the monitoring component. And determining the width information exceeding a preset threshold value and the transmission time of the width information.

And finally, calculating the running distance of the first vehicle according to the transmission time and the running speed of the sorting trolley, and determining the number of the sorting trolley of the deformation secondary plate according to the length of the sorting trolley.

The controller can also be connected with an alarm or a linear motor. When the monitored width information of a certain sorting trolley secondary plate exceeds a preset threshold value, the deformation quantity of the secondary plate is over large, and the secondary plate is easy to scratch and rub a linear motor. The controller can control the alarm to warn or stop the operation of the linear motor.

The monitoring system of the secondary plate can monitor the width information of the secondary plate of the sorting trolley in the working process of the sorting trolley, and further determine whether the deformation amount of the sorting trolley exceeds the safety range. And then through controlling linear electric motor or alarm, can avoid sorting dolly to cut the condition emergence of rubbing linear electric motor to pieces, improved this monitoring system's reliability. Meanwhile, the controller can determine the sorting trolley corresponding to the secondary plate with the overlarge deformation amount, and therefore maintenance efficiency is improved.

Finally, the present disclosure also provides a cross-belt sorter. The cross-belt sorter includes a controller and a monitoring system for a secondary board. The monitoring system of the secondary board is the monitoring system of the secondary board of each embodiment.
