[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please refer to Figures 1-5. This embodiment discloses a machine-based control system, including a frame 1 and several sets of high-speed book-splitting devices 3 spaced apart on the frame 1 for dispensing individual books. The frame 1 also has a book-stacking channel 2 for stacking the individual books dispensed by the high-speed book-splitting devices 3 into sets of books. Each high-speed book-splitting device 3 includes a hopper 32 and a servo motor 31 for pushing the books out of the hopper 32. The system is characterized by further including a control cabinet 4 disposed within the frame 1. The control cabinet 4 includes a power supply circuit 409, a PLC controller 401, and several sets of servo control units for individually controlling each set of high-speed book-splitting devices 3. The power supply circuit 409 supplies power to the equipment. Each servo control unit includes a servo control driver 402, and each servo control driver 402 is electrically connected to a corresponding servo motor 31. The PLC controller 401 is electrically connected to several servo control units for individually controlling each set of high-speed book-splitting devices 3. The system includes a book dispensing counter 403 for counting the number of books dispensed by the high-speed book dispensing device 3, several shortage sensors 404 for individually detecting shortages of books on each high-speed book dispensing device 3, several dispensing switches 407 for individually controlling the start of each group of servo motors 31, and several stop switches 408 for individually controlling the stop of each group of servo motors 31. The shortage sensors 404 are located at the bottom of the hopper 32. The PLC controller 401 is an Easy521 model. The driver 402 is model SV630P. In this embodiment, the power supply circuit 409 includes a 220V power supply input line 4041, a first switching power supply 4042 electrically connected to the 220V power supply input line 4041 and used to convert 220V to DC 48V, and a second switching power supply 4043 electrically connected to the 220V power supply input line 4041 and used to convert 220V to DC 24V. The 220V power supply input line 4041 includes an L line, an N line, and a PE line.

[0025] Preferably, to facilitate users' timely and intuitive understanding of which high-speed book sorting device 3 is in normal operation, fault, or material handling status, the high-speed book sorting device 3 also includes a red fault alarm light 33, a green normal operation reminder light 34, and a yellow material shortage alarm reminder light 35 located on the side of the hopper 32. The red fault alarm light 33, the green normal operation reminder light 34, and the yellow material shortage alarm reminder light 35 are all electrically connected to the PLC controller 401. In this embodiment, the power supply for the PLC controller 401, the red fault alarm light 33, the green normal operation reminder light 34, and the yellow material shortage alarm reminder light 35 is a 24V voltage output from a switching power supply 4042. Each servo control driver 402 is directly connected to the L and N terminals of the 220V power supply input line 4041.

[0026] As shown in Figure 6, preferably, the circuit breaker switch 407 is a relay switch. Taking one set of circuit breaker switches 407 as an example, the relay switch includes a relay coil Z1 and a normally open contact K1. One end of the relay coil Z1 is connected to the emitter C of an NPN transistor Q1, and the collector C of the NPN transistor Q1 is connected to a 24V voltage. The other end of the relay coil Z1 is connected to the ground terminal GND. The base of the NPN transistor Q1 is connected to the PLC controller 401. The normally open contact K1 is connected between a corresponding servo control driver 402 and the L line of the 220V power supply input line 4041. This enables the PLC controller 401 to stop working when the servo control driver 402 needs to be stopped. When the NPN transistor Q1 is cut off, the relay coil Z1 is de-energized and opens. At this time, the normally open contact K1 is open, so the L line of the 220V power input line 4041 cannot transmit the current signal to the servo control driver 402. The servo control driver 402 stops working, and the corresponding servo motor 31 also stops working. When the servo motor 31 needs to be activated, the PLC controller 401 drives the NPN transistor Q1 to amplify the signal, energizing the relay coil Z1. At this time, the normally open contact K1 changes from normally open to normally closed, so the L line of the 220V power input line 4041 transmits the current signal to the servo control driver 402. The servo control driver 402 then operates, and the corresponding servo motor... 31 also works. The connection structure of the relay switches of the other circuits refers to the connection structure of the relay switch of this circuit. The stop switch 408 is also a relay switch. The relay switch used in stop switch 408 includes a relay coil Z2 and a normally closed contact K2. Taking one set of stop switches 408 as an example, one end of the relay coil Z2 is connected to the emitter C of an NPN transistor Q2. The collector C of the NPN transistor Q2 is connected to a 24V voltage. The other end of the relay coil Z2 is connected to the ground terminal GND. The base of the NPN transistor Q2 is connected to the PLC controller 401. The normally closed contact K2 and the normally open contact K1 of the same circuit are connected in series in a corresponding servo control driver 402 and a 220V power supply. Between the L lines of input line 4041, when it is necessary to stop the servo control driver 402, the PLC controller 401 drives the NPN transistor Q2 to conduct, energizing the relay coil Z2. At this time, the normally closed contact K2 changes from normally closed to normally open. Therefore, the L line of the 220V power supply input line 4041 cannot transmit the current signal to the servo control driver 402, and the servo control driver 402 stops working. The corresponding servo motor 31 also stops working. When it is necessary to start the servo motor 31, the PLC controller 401 drives the NPN transistor Q2 to cut off, de-energizing the relay coil Z2 and opening it. At this time, the normally closed contact K2 resets to normally closed. If the normally open contact K1 connected in series with it changes from normally open to normally closed at this time...Therefore, the L line of the 220V power input line 4041 transmits the current signal to the servo control driver 402 of that channel. At this time, the servo control driver 402 of that channel operates, and the corresponding servo motor 31 also operates. The connection structure of the stop switches 408 of the other channels is the same as that of the stop switch 408 of that channel.

[0027] Preferably, the PLC controller 401 is also electrically connected to an emergency stop button 406. Preferably, when the entire equipment fails, the emergency stop button 406 can be pressed manually to stop the equipment from working. The PLC controller 401 is also electrically connected to an audible and visual alarm 405 for alarm reminder when the equipment fails. This structure achieves audible and visual alarm reminder when the equipment fails by adding the audible and visual alarm 405.

[0028] The working principle of this structure is as follows: The user pre-sets the program according to the customer's packaging requirements for the notebooks. For example, if only two colors of notebooks are used, only two sets of high-speed book sorting devices 3 can be used, while the other two sets of high-speed book sorting devices 3 are stopped. Three notebooks of each color are sent out, for a total of six notebooks in one package. If four colors of notebooks are required, the packaging requirements, such as the spacing between each color, can be set according to the actual situation. Once the program is set, the required notebooks of each color are placed in the hopper 32 of the corresponding high-speed book sorting device 3. Then, the PLC controller 401 controls the corresponding servo control driver 402 to work independently according to the set program, and finally controls the corresponding servo motor 31 to work, so that the notebooks in the corresponding hopper 32 are sorted. The books are conveyed into the book stacking channel 2, and after being stacked at the output port, they are then sealed in plastic using a packaging machine. During operation, the book counter 403 counts the number of books conveyed by each group of high-speed book sorting devices 3. Once the required quantity is reached, the corresponding group of high-speed book sorting devices 3 stops working. Therefore, this structure uses a PLC controller 401 to individually control the servo motor 31, achieving precise book dispensing (i.e., book pushing) according to the packaging quantity and packaging requirements. Ultimately, this allows merchants to freely combine and package books according to the buyer's packaging requirements, enabling the stacking of different colored books according to the buyer's requirements and quantities, thereby improving the versatility of the equipment.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
