Description

Parcel position tracking device and conveying equipment comprising same

Technical Field

The utility model relates to a package position tracking device and conveying equipment comprising the same, belonging to the technical field of logistics automatic conveying.

Background

With the development of society, people have higher and higher requirements on logistics speed, and logistics industry becomes more and more automatic to meet social demands. On an automatic logistics package sorting assembly line, a conveyor belt is generally adopted to transport packages, and two-dimensional codes on the packages are scanned through scanning equipment, so that package information is obtained, and various packages are classified based on the package information. However, if the interval between packages is too small, the scanning device may fail to detect, and the gates of the partitions may not respond enough, so that package sorting errors occur. Thus, there is a need for a device that can detect and control the package spacing.

The current control method of the parcel spacing in the logistics conveying system is to detect the arrival time difference of the parcel by a photoelectric sensor, calculate the distance between the parcel by combining the speed of a conveyor belt of conveying equipment, and then control the speed of the conveying equipment to adjust the parcel spacing. Or, the code wheel and the velometer are arranged on the power motor, so that the actual rotating speed of the motor is fed back in real time, and the moving distance of the conveyor belt is converted.

However, for the mode of detecting the package spacing through the photoelectric sensor, the belt conveying speed is changed frequently due to frequent acceleration and deceleration of the conveying equipment, the actual spacing between the packages is in error with the theory, and the situation that the package spacing is smaller occurs in practical application, so that the accurate detection and real-time control of the package position are not facilitated. However, for the way of installing the code wheel on the motor, the assembly space of the code wheel needs to be arranged at the time of design, but for some conveying equipment which is already put into operation and needs to be added with a wrapping position detection function later, the refitting of the motor part is time-consuming and labor-consuming.

An embodiment of the first aspect of the present utility model provides a package position tracking device, which is installed at the bottom of a conveying apparatus, and mainly includes a bracket 100, a swing arm 200, a speed measuring assembly 300, and an elastic member 400. By the acting force of the elastic member 400, the end of the swing arm 200 approaches to the conveyor belt 800 in the conveying device, so that the pinch roller 310 at the end of the swing arm 200 is attached to the conveyor belt 800 and can be driven by the conveyor belt 800, and the code wheel 320 coaxially fixed with the pinch roller 310 also rotates. The sensor 340 can acquire the rotation speed of the code wheel 320, so as to calculate the moving distance of the conveyor belt 800, and provide data support for determining the package position. Compared with the traditional mode of adopting photoelectric sensor to measure distance, the mode of adopting the code wheel 320 to measure speed and then measure distance has higher accuracy, and the detection result can be fed back in real time in the application scene that the moving speed of the conveyor belt 800 is changed frequently. Compared with the traditional mode of installing the code wheel on the motor output shaft, the wrapping position tracking device does not need to refit the motor, so that the improvement cost is reduced, the installation is simpler and more convenient, and more application scenes can be applied.

An embodiment of the second aspect of the present utility model provides a conveying apparatus, including the above package position tracking device.

Referring to fig. 1 to 2, a package position tracking device according to an embodiment of the first aspect of the present utility model includes a bracket 100, a swing arm 200, a speed measuring assembly 300, and an elastic member 400, wherein the bracket 100 is a main body structure of the package position tracking device and is used for supporting other components. The bracket 100 is formed in a plate shape and is made of a metal material for being mounted on the bottom of the conveyor belt 800 (refer to fig. 6).

The swing arm 200 is a movable member hinged to the bracket 100 so as to be capable of being turned around the hinge shaft. A through hole is provided at an end of the swing arm 200 for installing the speed measuring assembly 300.

The tachometer assembly 300 is a means for detecting the linear velocity of movement of the conveyor belt 800, and includes a pinch roller 310, a code wheel 320, a rotation shaft 330, and a sensor 340. Wherein the rotation shaft 330 is inserted into the through hole of the swing arm 200 and can rotate therein, and both ends thereof are fixedly connected to the pressing wheel 310 and the code wheel 320, respectively, such that the pressing wheel 310 and the code wheel 320 coaxially rotate, and the angular velocities of both are maintained to be identical. Referring to fig. 4, the code wheel 320 is provided with a circumferential array of sensing teeth 321 distributed about its central axis. The sensor 340 is mounted on the swing arm 200 and faces the code wheel 320, and when the code wheel 320 rotates, the sensor 340 can be triggered by the detection teeth 321 on the sensor 340 when passing the sensor 340, so that a speed measuring effect is achieved.

Further, to reduce slippage between puck 310 and conveyor 800, puck 310 is embodied as a rubber wheel, thereby increasing friction with conveyor 800.

In some embodiments, the elastic member 400 is a compression spring, both ends of which are connected to the bracket 100 and the swing arm 200, respectively, and always maintain a compressed state. Specifically, the connection point between the compression spring and the swing arm 200 is a first connection point, and the hinge point between the swing arm 200 and the bracket 100 is a hinge point, and the hinge point is located between the first connection point and the through hole, so that when the first connection point receives downward force of the compression spring, the end of the swing arm 200 rises with the hinge point as a fulcrum, and then drives the pinch roller 310 to rise to be attached to the conveyor belt 800.

In the present embodiment, the elastic member 400 is a tension spring, both ends of which are connected to the bracket 100 and the swing arm 200, respectively, and always maintains a stretched state. Specifically, the connection point of the tension spring and the swing arm 200 is a second connection point, the hinge point of the swing arm 200 and the bracket 100 is a hinge point, and the second connection point is located between the hinge point and the through hole, so that when the second connection point pulls the upward acting force of the tension spring, the end of the swing arm 200 rises with the hinge point as a fulcrum, and then the pinch roller 310 is driven to rise to be attached to the conveyor belt 800.

Further, the package position tracking device further comprises a limiting plate 500 which is in a shape of a C, two ends of the limiting plate are connected with the bracket 100, and the swing arm 200 passes through the limiting plate. When the falling range of the swing arm 200 is too large, the bottom of the swing arm 200 is contacted with the limiting plate 500, so that the lower limit of movement of the swing arm 200 can be limited by the limiting plate 500, and the swing arm 200 is prevented from falling to cause injury.

Further, referring to fig. 2 to 4, the middle parts of the swing arm 200, the pressing wheel 310 and the code wheel 320 are hollowed out, so that the weight of the device can be reduced, the total weight of the device is reduced, and the device is convenient to assemble.

Referring to fig. 5 to 6, a second aspect of the present utility model provides a conveying apparatus including the above-mentioned wrapping position tracking device, further including a driving roller 600, a driven roller 700, and a conveyor belt 800, the conveyor belt 800 being wound around the driving roller 600 and the driven roller 700, the driving roller 600 being adapted to be connected to an output shaft of a motor, so that the driving roller 600 can drive the conveyor belt 800 to move.
