將標(biāo)簽放卷、牽引、送出、裁切的機(jī)構(gòu)構(gòu)成，可以由多種類型的標(biāo)站，采用收放卷的高速運(yùn)動(dòng)控制技術(shù)來保障穩(wěn)定的張力，以為精準(zhǔn)送標(biāo)、切標(biāo)提供保障。標(biāo)簽的收放卷機(jī)構(gòu)，其放卷必須確保與大盤同步，并能夠進(jìn)行補(bǔ)充調(diào)整，而收卷則采用扭矩控制模式，帶擺輥的方式。通常送標(biāo)帶色標(biāo)的方式，送標(biāo)控制由電子凸輪控制及鎖標(biāo)（LATCH）功能配合完成，確保能夠精準(zhǔn)而又平穩(wěn)的送標(biāo)過程。在這個(gè)過程中，必須對(duì)色標(biāo)、主軸編碼器信號(hào)進(jìn)行微秒級(jí)的預(yù)測(cè)和延時(shí)處理，以確保高速中的信號(hào)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
