The Servo Pusher Type 2157 is part of the Heye Modular Servo Technology.
This Pusher is used at IS-Machines with up to 24 sections - preferably in double gob operation.
The design principle fulfills highest operational safety. There is no risk of squeeze and cut.
The Pusher has a very low weight as it only consists of few components. Hence, mounting and
demounting is simple and safe.
As the Pusher is operated without any pneumatic means to increase the speed there is no risk of
article deformation by compressed air or vacuum.
By the modular design both right-hand and left-hand operation of the Pusher is possible.
This minimizes the spare parts stocking.
Instead of the air cylinder used so far the Pusher is now driven by two independently operating
servo motors. The directly driven axes only need few operating elements. This reduces the
servicing considerably and simplifies repairs.

Motion Profile of the Pusher
Compared with air cylinders the advantage is that the push-out and retract motion of the pusher
fingers is carried out controlled and absolutely reproducible.
Advantages of the system
- Compact and flexible.
- Service reduced operation, minimum wear, long lifetime.
- Simple operation. Parameter setting via dialogue even during run.
- Motion and speed profiles can be adapted to the article geometry and transport speed even
during run.
- To support the bottle transport compressed air and vacuum is not needed. Accordingly the
articles will not be deformed.
- Minimization of danger spots as all driving parts are arranged below the machine conveyor
level.
- Exchangeability of components in a section without stopping the entire system.
- Quick and simple exchange of the entire finger arm.
- Robust and solid pusher fingers made of stainless steel (”soft touch” plating on request).
- No active electronics in the machine area.
- In case of failures the pusher always returns to its home position. This avoids that the pusher
stops in the article stream. Thus, no blockages on the machine conveyor.
- Automatic restart of the Pusher after a blockage.
- Switching output available to switch the gob off or to stop the section if the Pusher completely
failed.
- Coupling with any IS E-Timing possible.
- Also available for TG applications.

Heye Modular Servo Technology (HMST)
The HMST is a trend-setting drive concept to control servo drives in the IS-Machine and their periphery.
The modular system design allows a system-specific solution including the option to be upgraded.
The standard system consists of :
- an infeed cabinet and a module cabinet,
- a PC with process visualisation and the option to link all Heye Hot End Drives.
HMST Main Menu
You can reach the menu level of a section or of a peripheral device by clicking on the relevant display in the
main menu.
Menu of a Machine Section
The menus of the individual servo mechanisms can be opened by clicking on the corresponding display.
Advantages of the process visualization
- High availability by an independently operating visualization and real time control.
- Easy access on all parameters.
- Article administration for all process parameters allows short job change times.
- Error report for all systems connected.
- Option to link all Heye Hot End Equipments via CAN-Bus / Ethernet makes the entire system
easy-to-follow.
- Use of Windows XP / Windows 2000 as operating system on a standard PC
