Description

Logistics transmission roller control system with on-machine setting function

Technical Field

The present invention relates to a control system for a logistics transport roller, and more particularly, to a control system for a logistics transport roller with an on-machine setting function.

Background

With the vigorous development of logistics industry, the transportation technology of transporting goods by logistics operators determines the speed and efficiency of goods circulation in society. Today, most logistics operators use rollers as a medium for transporting goods.

Referring to fig. 10, a typical logistics belt 102 is provided with a plurality of rollers 103 to accelerate the flow of goods. Not every roller 103 of the plurality of rollers 103 is controlled, i.e. most of the plurality of rollers 103 only passively rotate, but only a small portion of the rollers 103 actively rotate under the control of a motor to advance goods and drive most of the plurality of rollers 103 to passively rotate. And wherein each motor includes a controller 104.

Referring to fig. 11-12, when one of the plurality of controllers 104 is inspected in focus, it can be seen that the controller 104 includes a housing 105 and a plurality of switches 106. The housing 105 includes an opening 110, and the opening 110 exposes the plurality of switches 106 within the housing 105. The switches 106 are disposed on a circuit board 101 in the housing 105, and the switches 106 are electrically connected to a processor 109 on the circuit board 101. Thus, a logistics worker can generate a plurality of switch signals by operating the switches 106 to control the operation of the rollers 103 through the processor 109.

However, as can be seen from a careful examination of FIG. 12, the plurality of switches 106 are very tiny and are closely spaced together. Even if the names 107 corresponding to the plurality of switches 106 are written on the housing 105, it is very difficult to confirm the contents of the plurality of names 107 on the housing 105 in a short time. In practice, when the practitioner needs to turn on or off one switch 106, he or she needs to spend heart blood looking for that switch 106 and take more heart blood to carefully touch the other switches 106 to operate the controller 104. Therefore, the present controller 104 for controlling the plurality of rollers 103 is difficult to be effectively controlled even though it has an on-board operation function.

Further, the present controller 104 has only a simple display light 108 to indicate how the plurality of rollers 103 are currently operating. Although the display light 108 may be an LED light, i.e., may change color to indicate different roller operating conditions, it is not so convenient to indicate the possible operating conditions of the plurality of rollers 103. In short, the plurality of switches 106 respectively correspond to two states, and thus the drum may have more than ten operating states. The present controller 104 is connected to an external device through an external port 111 to completely display the working status of all the rollers. The external port 111 is disposed on the circuit board 101, and the external port 111 is electrically connected to the processor 109. In practical use, this is very inconvenient, because the logistics operators cannot instantly grasp any working state content, and the external device needs to be connected first to confirm the working state content to continue the operation.

Therefore, it can be seen that the controller 104 for controlling the rollers 103 in the conventional logistics belt 102 has the function of on-board operation, but is not effectively and time-saving controlled by the logistics operators due to the dense arrangement of the switches 106 and the failure of the display lamp 108 to completely display all the working status. This, in turn, reduces the efficiency of the logistics provider and reduces the speed at which logistics goods are transported by the plurality of rollers.

Detailed Description

Referring to fig. 1 and 2, the present invention is a control system for a logistics transport roller with on-board configuration. The logistic transmission roller control system with the on-board setting function is arranged on a circuit board 1, and comprises a motor module 10, a driving module 20, a control module 30 and a man-machine interface module 40.

The driving module 20 is electrically connected to the motor module 10, and the control module 30 is electrically connected to the driving module 20 and the human-machine interface module 40. The control module 30 stores a plurality of control menus, and the human-machine interface module 40 has a screen unit 41. The screen unit 41 displays the control menus of the control module 30 so that a user can know the contents of the control menus. The content in the control menus includes at least one control mode for controlling the operation of the driving module 20. When the human-computer interface module 40 generates a selection signal, the control module 30 sets a corresponding control mode according to the selection signal, and controls the driving module 20 to drive the motor module 10 to operate according to the control mode.

Referring to fig. 2 and 3, in a first embodiment of the present invention, the hmi module 40 further includes a key unit 42. The screen unit 41 is a display screen of an Organic Light-emitting Diode (OLED), but not limited thereto. When the key unit 42 is activated, the key unit 42 generates the selection signal correspondingly, and the key unit 42 transmits the selection signal to the control module 30. When the control module 30 receives the selection signal, the control module 30 controls the screen unit 41 to display the control mode corresponding to the selection signal.

In the first embodiment, the present invention further includes a communication module 50, and the communication module 50 is electrically connected to the control module 30. The control module 30 generates a synchronization signal according to the control mode, and the control module 30 sends the synchronization signal through the communication module 50. Further, the communication module 50 is a network module, and the communication module 50 sends the synchronization signal to another device connected to the communication module 50 through a network packet. The network is connected to another device of the communication module 50, namely another control system of the logistic transmission roller with on-board setting function, which is called as a number two system for short. The second system has another communication module 50, and the other communication module 50 is referred to herein as a second communication module. Therefore, a network connection is formed between the communication module 50 and the second communication module of the second system. In detail, the communication module 50 is electrically connected to a network port 51 disposed on the circuit board 1, so that the communication module 50 is connected to the second communication module through the network port 51, and exchanges messages between the two systems. The communication module 50 sends the synchronization signal and the second communication module confirms the reception of the synchronization signal.

When the second system receives the synchronization signal through the second communication module, the second system generates the control mode corresponding to the synchronization signal to control the other driving module 20 of the second system to drive and control the other motor module 10 of the second system to operate. In other words, the synchronous signal is sent out by the communication module 50, and the selection signal generated by the key unit 42 can be copied and applied to the second system connected to the communication module 50, so that the present invention operates as a first system and the second system synchronously.

In another embodiment, the communication module 50 can be further connected to a third system. The third system is another logistics transmission roller control system with an on-board setting function. The logistic transmission roller control system with the on-machine setting function, the second system and the third system form a series network connection. When the invention receives the synchronous signal transmitted by the third system, the invention also generates the control mode according to the synchronous signal, and the invention continuously transmits the synchronous signal to the second system to form the relay of the synchronous signal. Therefore, the first system, the second system and the third system can synchronously operate.

Referring also to fig. 4, the present invention can be implemented on a conveyor belt 2. The material flow conveyer belt 2 comprises a plurality of rollers 3, wherein a small part of the rollers 3 are controlled by the invention to actively rotate, and the rest of the rollers 3 only passively rotate when being stressed. The on-machine setting logistics transport roller control system, the second system and the third system of the present invention will be set along the logistics transport belt 2. The connections between the network ports 51 are made by network lines 5 between the present invention and the second and third systems along the logistics belt 2. Compared with the prior art that only a single signal is transmitted through a wire and is limited by the problem that the analog signal decreases along with the distance, the invention can more effectively maintain the communication between the communication modules 50 in a digital signal communication mode of network packets so as to prolong the number of systems which can be reached by the synchronous signal.

Referring to fig. 5 to 9 together, as shown in fig. 2, the key unit 42 further includes an upper key 42A, a lower key 42B, a left key 42C and a right key 42D in the first embodiment. In this embodiment, pressing any key of the key unit 42 for a long time causes the hmi module 40 to generate a power-on signal, and the hmi module 40 transmits the power-on signal to the control module 30 to enable the control module 30 to start operation. The control module 30 will display a startup picture through the screen unit 41, and the startup picture is shown in fig. 5.

In the first embodiment, the screen unit 41 displays one of the plurality of control menus and a cursor 40A. In addition, the control menus of the control module 30 in this embodiment further include a first control menu 30A, a second control menu 30B and a third control menu 30C. The second control menu 30B is the next-layer extension menu of the first control menu 30A, i.e., the first control menu 30A is the previous-layer menu of the second control menu 30B. The third level control menu is the next level extension menu of the second level control menu 30B, i.e., the second level control menu 30B is the previous level menu of the third level control menu.

Regardless of which layer of menu is displayed by the screen unit 41, when the up button 42A of the button unit 42 is actuated, the cursor 40A displayed by the screen unit 41 moves upward in the displayed control menu. When the key 42B of the key unit 42 is activated, the cursor 40A displayed by the screen unit 41 moves downward in the displayed control menu. When the right button 42D of the button unit 42 is activated, the button unit 42 correspondingly generates the selection signal, and the screen unit 41 makes a selection at the cursor 40A in the displayed control menu to set the corresponding control mode. When the left button 42C of the button unit 42 is activated, the button unit 42 generates a top-back signal, and when the button unit 42 generates the top-back signal, the control module 30 controls the screen unit 41 to display a top menu.

Further, when the key unit 42 generates the selection signal, the control module 30 determines whether the control mode set according to the selection signal further corresponds to the next layer of the extended menu. If the control mode set according to the selection signal further corresponds to the next-layer extension menu, the control module 30 controls the screen unit 41 to display the next-layer extension menu. If the control mode set according to the selection signal does not further correspond to the next level of extended menu, the control module 30 controls the screen unit 41 to display the previous level of menu.

For example, fig. 6 shows the first layer control menu 30A displayed on the screen unit 41, and fig. 7 to 9 show the second layer control menu 30B displayed on the screen unit 41. As can be seen in fig. 8, the cursor 40A is shown as a triangle in this embodiment, and the cursor 40A refers to a control mode of a rotation direction (Rotation Direction) in the second layer control menu 30B. The direction of rotation defines the direction in which the control module 30 controls the rotation of the motor module 10. When the cursor 40A is displayed in the second layer control menu 30B as shown in fig. 8, and when the left button 42C of the button unit 42 is activated, the screen unit 41 correspondingly displays the previous layer menu, i.e. the first layer control menu 30A of fig. 6. So at this point, the cursor 40A will point to the content in the first layer control menu 30A.

When the cursor 40A is displayed in the second layer control menu 30B as shown in fig. 8, and when the right button 42D of the button unit 42 is activated, the control mode set by the selection signal is that the cursor 40A indicates the rotation direction in the second layer control menu 30B. The screen unit 41 will display the next layer of extended menu, i.e. the third layer of control menu, extended from the control mode for the direction of rotation. At this point, the third level control menu provides for selection of the control mode including a Clockwise (Clockwise) rotation and a counter-Clockwise (counter Clockwise) rotation. Assuming that the cursor 40A indicates the clockwise rotation control mode in the screen unit 41 and the right button 42D of the button unit 42 is activated, the control mode set by the selection signal is the clockwise rotation control mode in the cursor 40A indicates the third layer control menu. Thus, the control module 30 starts to control the motor module 10 to rotate clockwise. And, since the control mode of the clockwise rotation does not further correspond to the next level of extended menu, the control module 30 causes the screen unit 41 to display the previous level of menu, i.e. the control module 30 causes the screen unit 41 to jump back to display the second level of control menu 30B.

In this embodiment, the second layer control menu 30B of fig. 7 is the next layer extension menu extended from a Normal Display (Normal Display) in the first layer control menu 30A of fig. 6. In addition, the second layer control menu 30B in fig. 8 is the next layer extension menu extended by an upper Zone Setting menu (U Zone Setting) or a lower Zone Setting menu (D Zone Setting) in the first layer control menu 30A in fig. 6. The second level control Menu 30B of FIG. 9 is the next level extension Menu extended by an Input/Output Menu (I/O) in the first level control Menu 30A of FIG. 6. The control modes shown in the second control menu 30B in fig. 9 are the technical details of controlling the driving module 20 to drive the motor module 10 in this embodiment, and are not directly related to the improvement of the present disclosure, so they will not be described herein.

In this embodiment, the present invention further includes an optical sensing module 60 and a power module 70, and the optical sensing module 60 and the power module 70 are electrically connected to the control module 30 respectively. The power module 70 provides power to the control module. In addition, the control module 30 further includes a power monitoring unit 31 and a motor control unit 32. The control module 30 further stores a normal power data, and the normal power data includes an operating voltage threshold.

The power monitoring unit 31 detects whether the voltage value of the power supplied by the power module 70 is smaller than the operating voltage threshold according to the normal power data. When the power monitoring unit 31 detects that the voltage value of the power supplied by the power module 70 is smaller than the operating voltage threshold, the power monitoring unit 31 determines that a power abnormality occurs, and the power monitoring unit 31 generates a power abnormality data. The control module 30 displays an error message through the screen unit 41 according to the power abnormality data.

The motor control unit 32 controls the driving module 20 to drive the motor module 10 according to the control mode, and the motor control unit 32 detects whether the motor module 10 is driven by the driving module 20. In other words, the motor control unit 32 detects whether the motor module 10 is jammed or encounters other external force obstruction, and cannot be driven by the driving module 20 as desired. When the motor control unit 32 detects that the motor module 10 is not driven by the driving module 20, the motor control unit 32 determines that an abnormal working state occurs, and the motor control unit 32 generates abnormal working state data. The control module 30 displays a warning message through the screen unit 41 according to the abnormal data of the working state.

The motor control unit 32 further detects the operation states of the motor module 10 and the driving module 20 to generate a signal state data. The control module 30 displays a signal status message through the screen unit 41 according to the signal status data.

Furthermore, the control module 30 also has a built-in data. The built-in data includes a plurality of indicators related to the operation states of the motor module 10 and the driving module 20, and each of the indicators includes at least one threshold value. Thus, the control module 30 can detect whether the plurality of indicators related to the operation states of the motor module 10 and the driving module 20 are wrong or abnormal. For example, according to the built-in data, the motor module 10 should normally maintain a rotational speed of 60 revolutions per minute (Revolutions Per Minute; RPM), so that a rotational speed index of the motor module 10 includes a threshold of 60 RPM. When the rotation speed of the motor module 10 is 67RPM, the control module 30 detects that the rotation speed of the motor module 10 exceeds the threshold value of 60RPM, so that the control module 30 determines that an abnormal state with too high rotation speed occurs, and the control module 30 displays the abnormal state in the form of a code through the screen unit 41.

As shown in FIG. 7, the error message, the warning message, the signal status message, and various abnormal or error status are displayed in the form of codes through the screen unit 41. In this embodiment, the meaning of each code is as shown in the following table one:

list one

In the first table, the code UV corresponds to the power supply module 70 providing the power with a voltage value smaller than the operating voltage threshold, and the power monitoring unit 31 determines that the power abnormality occurs. The error message is the code UV. In addition, the code ULock corresponds to the situation that the motor module 10 cannot be driven by the driving module 20 as expected, and the motor control unit 32 determines that the abnormal working state occurs. The warning message is the code ULock. The code USpeed corresponds to the motor control unit 32 detecting the working state of the motor module 10 to generate the signal state data of a rotation speed of the motor module 10. The control module 30 displays the signal status message as display data corresponding to the code USpeed through the screen unit 41 according to the signal status data.

Since the exception or error meaning of each code is not directly related to the improvement of the present invention, the corresponding details of each code are not explained in detail. The display list is for illustration only, and the screen unit 41 of the present invention is shown to fully display rich operation message content that cannot be displayed in real time by conventional drum controllers.

In this embodiment, the power module 70 further includes a power supply voltage conversion circuit, which provides 24 volts of power for the present invention. The optical sensing module 60 is disposed on the logistics belt 2, and the optical sensing module 60 further comprises an infrared sensor. When the infrared sensor detects dynamic motion, it is determined that the goods flowing on the logistics belt 2 begin to appear. At this time, the optical sensing module 60 generates a start signal to the control module 30, so that the control module 30 starts to start the motor module 10 to operate after receiving the start signal, so as to convey the goods on the logistics conveyer 2.

In addition, the motor control unit 32 of the control module 30 performs conversion between a digital control signal and an analog signal of the control module 30 in a Pulse-width modulation (PWM) manner to control the driving module 20 to drive the motor module 10 to rotate. In detail, the driving module 20 includes a first driving unit 21 and a second driving unit 22, and the motor module 10 includes a first motor unit 11 and a second motor unit 12. The first driving unit 21 is electrically connected to the first motor unit 11 to drive the first motor unit 11 to operate, and the second driving unit 22 is electrically connected to the second motor unit 12 to drive the second motor unit 12 to operate. The first motor unit 11 and the second motor unit 12 each further include a Hall sensor (Hall sensor) and a temperature sensor. The hall sensors of the first motor unit 11 and the second motor unit 12 respectively and correspondingly sense the rotation speeds of the first motor unit 11 and the second motor unit 12, and respectively transmit a rotation speed signal to the motor control unit 32 of the control module 30, so that the motor control unit 32 respectively controls the operation of the first motor unit 11 and the second motor unit 12. The temperature sensors of the first motor unit 11 and the second motor unit 12 respectively and correspondingly sense the temperatures of the first motor unit 11 and the second motor unit 12, and respectively transmit a temperature signal to the motor control unit 32 of the control module 30, so that the motor control unit 32 respectively controls the operation of the first motor unit 11 and the second motor unit 12.

The upper region and the upstream indicated in the above table are intended to electrically connect the states of the first driving unit 21 and the first motor unit 11 of the present invention. The lower zone and downstream referred to in Table I are intended to electrically connect the states associated with the second drive unit 22 and the second motor unit 12 of the present invention.

In the logistic transmission roller control system with the on-machine setting function, the screen unit 41 of the man-machine interface module 40 is used for displaying the plurality of control menus, and the man-machine interface module 40 is used for generating the selection signal, so that the difficulty of the user in operating the roller controller is simplified. The user can easily set the control mode by generating the selection signal through the man-machine interface module 40 having an on-board operation function and viewing the contents of the plurality of control menus through the screen unit 41, so as to efficiently set how the motor module 10 rotates the plurality of rollers 3. Moreover, compared to the prior art light signal, the man-machine interface module 40 can more efficiently present the status data of the motor module 10 running the plurality of rollers 3 through the screen unit 41, so as to assist the user in improving the efficiency of maintaining the plurality of rollers 3.
