Reducing production costs, shortening the production cycle, reducing resource consumption, and improving product quality, especially the ability to quickly respond to small orders, have become the key for enterprises to gain an active position in the fierce market competition.
[0003] At present, there are generally three production management methods for clothing production lines. The first is traditional package flow production, with a chaotic process and difficult control of personnel, efficiency, and quality. The second is lean beat single-piece flow management, which can be well controlled in terms of process, personnel, efficiency, and quality, and is also a very successful management model at present. However, due to the current unstable personnel and a large number of styles with small quantities in orders, the management ability cannot keep up, resulting in the difficulty for the vast majority of small and medium-sized enterprises to operate successfully. The third is the hanging intelligent dispatching production line, which can be freely dispatched to flexibly respond to the problems of unstable personnel and many styles with small quantities.

[0007] In a specific embodiment of the present invention, a power supply circuit is further included.

[0020] Please refer to Figure 3, the scheduling extension device 3 further includes a power supply circuit, and the power supply circuit includes a voltage regulator U3, capacitors C2 to C4, a diode D5, and a resistor R17. The voltage regulator U3 uses an L7805 to convert a 24V DC power supply into a 5V DC voltage to supply power to this device.
[0021] Furthermore, the production line has a signal recognition circuit board and a main control circuit board. The signal recognition circuit board is respectively connected to the RFID reader 12, interface J1, interface J2, and interface J3. When the RFID reader 12 recognizes that the turnover basket 11 carrying the RFID card 111 arrives at station 2, the signal recognition circuit board outputs an air valve signal to interface J2 and a card reading signal to interface J3. The single-chip microcomputer U2 controls the light-emitting diode LED of the big button KEY1 to light up and controls the buzzer U1 to sound, warning the staff that there is a turnover basket 11 arriving at station 2, realizing the refined management of station 2 and quickly transmitting the status information of station 2.
[0022] When the relay K1 is normally closed, it is connected in series to the entire production line, that is, the power supply circuit of the motor of the conveying device 1 is connected. When there are air valve signals and card reading signals input to the circuit, the relay K1 disconnects from the normally closed state, causing the motor of the conveying device 1 to pause. When the turnover basket 11 is removed, the card reading signal disappears, and the relay K1 returns to the normally closed state, and the production line motor continues to run. The main control circuit board is connected to interface J4 and interface J5, and controls the motor of the conveying device 1 to stop or continue running according to the opening and closing of the relay K1. The main control circuit board is the control system main board of the existing production line; the signal recognition circuit board is used to recognize the card reading signal. There are many boards with this function in the prior art, and no further description will be given here.
[0023] When the big button KEY1 is long-pressed, interface J1 continuously outputs a full station signal, and the signal recognition circuit board prohibits the RFID reader 12 from outputting an air valve signal and a card reading signal, and the current station 2 enters the shielding mode. Pressing the big button KEY1 again will exit the shielding mode.
[0024] Furthermore, in the shielding mode, short-pressing the big button KEY1 can be used as a semi-automatic beat mode. The semi-automatic beat mode means that the motor runs according to the beat, for example, runs once every 30 seconds, and transfers the turnover basket 11 to one station 2. If the big button KEY1 is short-pressed in the shielding mode, then the conveying device 1 will not run after 30 seconds until the big button KEY1 is short-pressed again.
[0025] See Figure 4 , P2, P3, P5, P6, P8, P9, P12 respectively correspond to pins 2, 3, 5, 6, 8, 9, 12 of the single-chip microcomputer U2. The working process of this device is as follows:
[0026] At the initial stage of the normal mode, P3, P8, P9, and P12 do not work.
[0027] Continuously detect the P5 air valve. At this time, P5 will have a low level for about half a second. P5 is triggered as long as it changes from high level to low level.
[0028] When P5 becomes low level, the P8 relay K1 outputs high level to make the relay K1 work, the P9 buzzer U1 outputs a signal to make the buzzer U1 work, the P3 large button KEY1 lights up, and P12 full station does not work. At this time, the large button KEY1 cannot be long-pressed.
[0029] Then continuously detect the P6 card reading signal. P6 should be at low level. If it becomes high level (lasting at least 1 second), then P8, P9, and P3 do not output at all. Then start to continuously detect P5 again. At this time, long-pressing the large button KEY1 is allowed.
[0030] When full station, long-pressing the P2 large button KEY1 switches to the shielding mode, records the variable, and the light-emitting diode LED of the P3 large button KEY1 stays on. The P8 relay K1 does not work, the P9 buzzer U1 does not work, and the P12 full station signal remains at high level.
[0031] At this time, short-pressing the large button KEY1, the light-emitting diode LED of the P3 large button KEY1 flashes quickly, the P8 relay K1 works, the P9 buzzer U1 sounds, and the P12 full station signal still remains at high level. Short-pressing the large button KEY1 again returns to the state where the light-emitting diode LED of P3 makes the large button KEY1 stay on, P8 does not work, P9 does not work, and P12 remains at high level.
[0032] The present invention combines the respective advantages of the second lean beat production and the third hanging intelligent scheduling mentioned in the background technology, runs in a ground loop, solves potential hazards such as visual safety, and the operation control system optimizes the hanging intelligent scheduling system. It uses plastic frames to replace the hanging clothes hanger clips to convey cut pieces, avoiding damage to the cut pieces by the clothes clips. The plastic frames are not limited by fabrics and styles, and can handle any fabric and any style. It can also freely choose between small batch flow and single-piece flow, and can handle component small batch flow and single-piece flow assembly.
[0033] This case is to optimize and match the scheduling of the difficulty and workload of all clothing processes and the production capacity of employees in real time during the production and manufacturing process, so as to make the best use of production resources to the greatest extent, improve production efficiency and the flexibility of the production line, which not only has profound theoretical significance but also has greater practical value.
