**执行摘要**
> Light, loose items such as rolls can shift or tip when a turntable starts turning and the film begins to pull on them.
> Our stretch wrapper solves this with a top press: a yellow arm lowers a plate onto the load and holds it down while the turntable turns and the film goes on.
> Film use follows from the **load perimeter** and its **height**. Both are set per project to your products.
目录
视频显示的内容
操作员将六个白色卷筒放在包装机的绿色转盘上，然后用透明薄膜覆盖。上方黄色机械臂将压机降下，压住卷筒并将其固定住。
转盘随后转动，胶片车沿着桅杆向下移动，胶片逐渐堆积在卷筒周围。临近结束时，操作员会再次上前整理胶片尾部。从始至终，卷筒始终保持直立并排列整齐。
顶压式包装机的工作原理
步骤 | 会发生什么 |
|---|---|
| Load | Items are grouped in the middle of the turntable |
| Film start | The film end is drawn across and held on the load |
| Press down | The top press lowers onto the load and holds it |
| Wrap | The turntable turns and the carriage travels the mast |
| Finish | The film is cut, the press lifts and the load is taken off |
随着薄膜张力的增加，压机可以阻止负载的抬起或移动。它还能保持顶层平整，使薄膜紧紧包裹在顶部边缘。
每卷胶卷的计划
示例：六卷胶卷以 3 × 2 组排列，每卷胶卷宽 120 毫米，高 250 毫米，胶卷长度为 250 毫米，重叠一半：
| 项目 | 金额 |
|---|---|
| Group footprint, 3 × 120 by 2 × 120 | 360 × 240 mm |
| Group perimeter, 2 × (360 + 240) | 1,200 mm |
| Advance per turn at half overlap | 125 mm |
| Spiral turns, 250 ÷ 125 | 2 |
| End turns, 2 at top and 2 at bottom | 4 |
| 薄膜铺设尺寸：6 × 1.2 米 | 约 7.2 米 |
短距离负载主要由末端转弯来处理。请在程序中根据需要进行设置。
当顶部按压有所帮助时
| Load | Why the press helps |
|---|---|
| Light rolls and cartons | They cannot lift or slide |
| Tall, narrow stacks | They do not tip as the table starts |
| Soft goods | The press keeps the top flat |
| Mixed groups | Items stay grouped as one pack |
重型、稳定的托盘货物通常不需要压机。
控制与安全
上压板向下压住货物，转盘随之转动。压板下降时，请勿将手放在货物顶部；转盘转动时，请勿靠近转盘。
适用的标准取决于目标市场。对于欧盟CE市场，ISO 12100规定了风险评估方法，EN 415-10规定了包装机械的通用要求。

工程常见问题解答
Q: What does the top press do?
A: It holds the load down on the turntable, so light or loose items cannot lift, shift or tip.
Q: What loads need a top press?
A: Light rolls, cartons, tall narrow stacks and soft goods.
Q: How much film per load?
A: Turns times perimeter. Our six-roll example lays about 7.2 m.
Q: Does it need a pallet?
A: No. The rolls in our video stand straight on the turntable.
Q: Do heavy pallets need a press?
A: Usually not. Heavy, stable loads stay put under film tension.
