A stamping production line generally consists of 5 to 6 press machines in sequence. The presses are connected by mechanical automation devices to transfer the processed parts. These mechanical automation devices are typically composed of robotic arms. After the processed parts are stamped and formed in the first press, they are transferred by the robotic arm to the next press to complete the second stamping process. Similarly, the workpiece transported from the last press is the target formed product.
Application of Schmeisser safety products in automotive manufacturing robot assembly lines
This high-speed stamping production line has very high requirements for automation. Due to its high complexity, while ensuring the functionality of the process, it is also necessary to ensure the safety of the production line. Its safety is to ensure that the production line will not cause any harm to the workers during the production operation, debugging, cleaning, and maintenance process. Usually, machine manufacturers or system integrators adopt various safety protection functions to improve the safety of stamping production lines.

Emergency stop device
In order to eliminate direct or imminent danger, every workstation and on-site electrical box in the press production line must be equipped with an emergency stop function. The emergency stop function can be achieved through one or more emergency stop devices. In practical use, emergency stop devices can only be used as additional preventive measures for machinery and equipment, and cannot replace necessary safety protection devices, nor can they be used as automatic safety devices.

It should be noted that there is a special requirement for the emergency stop device, that is, after giving the command signal for emergency stop, the operating head of the control device must be able to automatically move to the cutting position through a pre-set internal mechanical structure. This means that only devices with internal spring structures that can automatically lock after the operating force reaches the pressure point can meet this requirement. However, devices that achieve locking function through internal lifting actions cannot meet this requirement.
The Schmeisser EDRRZ series emergency stop device adopts pure metal operating components, and the electrical contacts have a direct disconnection action structure, which complies with IEC 60947-5-1.

Electromagnetic safety lock
To prevent personnel from encountering danger inside the press, various methods can be used, and installing movable protective doors is a very common one. When designing the protective door for the press production line, it should be able to prevent workers from entering the hazardous area until the dangerous movement of the machine stops or other hazardous factors are eliminated.
Electromagnetic safety locks can be used to monitor and lock the position of movable protective doors. The biggest feature of an electromagnetic safety lock is that it has a separate and detachable actuator.

Advantages of AZM300:
Adopting innovative star shaped ratchet and rotating shaft operation method, the advantage of this operation method is that when the safety door is closed, it is pulled to the bottom while maintaining a locked state.

● Independent coding, compliant with ISO14119, suitable for Cat 4/PLe/SIL3.
Two handed control device
Two handed control device
Each press must use at least one set of dual hand control devices for manual stamping operations. The dual hand control device belongs to the electrically sensitive safety protection device. Its function is to force someone to use both hands at the same time when operating machinery and equipment, giving a signal of dangerous action, so that they must stay in one place to ensure safety.
The dual hand control device is a safety protection device that requires simultaneous movements of both hands. This means that when starting or maintaining the operation of the machine equipment, as long as the dangerous movements of the machine equipment do not stop, the operator’s hands will be constantly restricted within a range far away from the dangerous area.
Schmeisser offers two types of dual hand button control devices made of SEPK and SEPG materials. Not only does it follow ergonomic principles, but it also complies with ISO13851.

Safety light curtain/grating
In the stamping production line, safety light curtains/gratings must be used for safety protection in the mold changing area and press area. When changing molds automatically, it is necessary to ensure that personnel do not enter the hazardous area. Due to the mold being placed in an open area outside the press line, a safety grating can be used for safety protection. Safety light curtains must also be installed in the interface area between the press and the robotic arm. To ensure that the press cannot perform stamping operations while the robotic arm or personnel are inside the press.
