將標簽放卷、牽引、送出、裁切的機構構成，可以由多種類(lèi)型的標站，采用收放卷的高速運動(dòng)控制技術(shù)來(lái)保障穩定的張力，以為精準送標、切標提供保障。標簽的收放卷機構，其放卷必須確保與大盤(pán)同步，并能夠進(jìn)行補充調整，而收卷則采用扭矩控制模式，帶擺輥的方式。通常送標帶色標的方式，送標控制由電子凸輪控制及鎖標（LATCH）功能配合完成，確保能夠精準而又平穩的送標過(guò)程。在這個(gè)過(guò)程中，必須對色標、主軸編碼器信號進(jìn)行微秒級的預測和延時(shí)處理，以確保高速中的信號實(shí)時(shí)同步。

bidirectional thyristor and transistor. Therefore, for the output end of the circuit, there are corresponding types of "relay output, transistor output, bidirectional thyristor output". Relay output and transistor output are the most common in PLC. Although they are both control devices, they are different. Transistor input and output are not electrically isolated, while relay is electrically isolated. When the volume is limited and the response time is very short, transistor control is often used; When the voltage is relatively high and the current is relatively large, and personal safety should be paid attention to, relays are often used. The relay output is generally strong current controlled by weak current. The output current and voltage are written on the shell of the relay. The specific differences between the two are as follows:
1. Different types of load voltage and current
Load type: transistors can only carry DC loads, while relays can carry AC and DC loads. Current: the maximum transistor current is 0.75a, and the maximum relay current is 2A. Voltage: the transistor can be connected to DC 24V (generally the maximum is about DC 30V, and the relay can be connected to DC 24V, maximum 30V or AC 220V).
2. The load carrying capacity of transistors is less than that of relays. The load carrying capacity of transistors is less than that of relays. When using transistors, sometimes other things need to be added to drive large loads (such as relays, solid-state relays, etc.).
3. The overload capacity of transistor is less than that of relay. Generally speaking, when there is a large impulse
