對于筷子，大家都熟悉不過，我們中國人講究趁熱吃，因此平時吃飯、吃面、特別是吃火鍋都離不開它。

筷子是怎么來的，聽過一個很有趣的民間故事：

相傳商朝的紂王，在用飯的時候，飯熱一點不行，湯冷一點也不行，如果不合商紂王的胃口，廚子的小命就不保了。而妲己作為與他朝夕相處的人，有一次，有人端上來一碗肉湯，十分燙嘴，想要端下去已經來不及，于是她拔下頭上的兩根簪子，撈起肉片，吹了一下，喂紂王吃下去。不曾想，紂王認為這是一件極其享受的事情，于是，為了討好紂王，妲己特制了一雙玉筷。事情流傳開來，從這以后，就有了各種各樣的筷子。

今天，小合要介紹的就是對筷子進行自動分類包裝的筷子包裝機控制系統

筷子包裝機-機型介紹

筷子包裝機是對餐具公司筷、竹木分體一次性衛生筷進行自動分類包裝的小型設備。

1、自動包裝功能。

2、薄膜自動封邊切割功能。應用自動化控制系統的筷子包裝機可以有效包裝工序及印刷貼標等造成的誤差，節省人力并降低能耗。并實現包裝機運行穩定、適用于任何薄膜連續包裝，保證包裝后的筷子密封、防潮、防污染、防破損。

本次H32-01控制方案應用于全自動筷子包裝機。全自動筷子包裝機，采用三邊壓專封口，通過制袋成型，筷子可自動送料、封口、切斷，是目前國內市場上一種集高科技、率的全自動筷子包裝機。

全自動筷子包裝機-控制原理筷子包裝機分追標模式與定長模式。

定長模式：

拉膜軸與刀軸按照凸輪表走，切出設定長度的筷子包裝膜。不追標。

追標模式：

根據包裝膜的色標，剪切規定位置，切233.5mm的筷子時，大速度可達800雙每分鐘。

控制難點

尋標與糾偏。需要不停的糾正當前位置，在主軸變速時，也需要定位準確。

全自動筷子包裝機-合信控制方案本設備采用H32薄型EtehrCAT總線PLC控制，搭配A3N伺服驅動，配備TP07觸摸屏操作的整套合信控制系統。采用電子凸輪追飛剪，整體速度穩定，快速度達到800雙/分鐘，線速度可達3145mm/S；同步運行，平衡可靠，適用于任何薄膜連續包裝。

的H32 （EtherCAT總線型）筷子包裝機對于速度迅捷，位置精準要求很高，運用合信CTH300系列H32PLC，走EtherCAT總線，通過飛剪模式快速，精準切膜，且穩定。快速度每一刀都在70ms內完成精準切膜。

H32-01支持PLCopen標準運動控制指令

可以直接以軸控方式進行配置、電子凸輪、電子齒輪、軸組插補等高階運動控制。output is a function of the input (in other words, when there are no state variables, such as Boolean feedback, set / reset coils, or flags). When using both stateless and state based functions, use CFC and SFC together.

Because connectivity is represented by lines between function blocks, it's easy to understａnd the flow of information and how it is modified along its path. If the function begins to become complex, it should be divided into smaller, more manageable sub blocks. If there are a large number of connections between blocks, these wires can be connected to pins of the data structure type.

The structure pin has three advantages

1. In the hierarchical structure design, unnecessary details are eliminated in each level, which makes it clearer and easier to understand;

2. Keep the function block small, you can view the whole information flow on one page;

3. Allow information to flow upstream and downstream to further reduce unnecessary details.

CFC provides a more concise and flexible method for PLC programmers who used LD to implement block based or hierarchical functions. CFC is faster to develop and easier to understａnd for future engineers who are responsible for maintaining or improving code.

·Layered design

Layered design is a practice of layer by layer design from many simple building blocks. Compared with the traditional flat design, layered design has many advantages

1. Customization;

2;

3. Testing and improvement;

4. Understanding and maintenance;

5. Easy to reuse.

Building block technology supports and encourages the same level of detail at each level of the hierarchy, which makes block technology easier to design and understand.
