Distance travelled by the stop to clear and lock (lower or raise) the pallet.
Component that stops the pallet.
Available in a number of designs (plastic stop, steel stop, tilt stop, various dimensions). The combination of pallet and stop materials is an important factor determining the achievable lowering force.
Similar basic products form a product group.
Basic products differ in their scope of application, usually in terms of the maximum pallet weight they can stop.
The order code reflects the composition of a product variant and uniquely identifies this. It is possible to order directly from Wörner using this code.
Working pressure of the pneumatic system. Specifications in data sheets (for the lowering force, for example) usually refer to a operating pressure of 6 bar.
Distance travelled by the stop when decelerating the pallet. The length of the damping stroke is important for the stopper‘s damping capacity.
For stopping with change of direction. Preferred solution for changes of direction during the conveying of shock-sensitive or fragile parts.
Scope of application
Identifies a stopper‘s damping capacity. Table specifying the maximum pallet weight that can be stopped at different conveyor speeds.
Lowering is a pneumatically or electrically driven movement. By contrast, the stop is raised into the locking position by spring force. Benefits: Easier to control because, for example, only one pneumatic connection is needed. When no compressed air is supplied, the stopper always moves to the locked position (safety feature).
Electronic, non-contact sensor system for the detection of certain stop positions.
Speed at which the pallet is transported.
For raising and positioning. Guarantees precise positioning and vertical lifting of the pallet and is ideal for rapid positioning tasks. The workpiece can be processed without vibration.
Inductive, non-contact sensor system for the detection of certain stop positions.
A unit‘s compressed air consumption expressed in litres per work cycle, usually at a working pressure of 6 bar.
Weight of the pallet and/or the workpiece.
Accessory available for many stopper models. Can be used to determine the position of the stop. For full functionality, further accessories are required (proximity switch, for example).
Variant derived from a basic product (for example in terms of lowering stroke, function, temperature range or stop design). The name of the product variant corresponds to the order code that can be used to order the unit from Wörner.
Force required to set a stationary body in motion or to continue to move a moving body in a constant way. Is a function of the coefficient of friction and weight of the body.
Coefficient of friction
Designates the friction between the conveyor equipment and pallet. Important for the design of the stopping point because both the damping and the lowering capacity depend on the friction.
For preventing rebound. Holds the pallet loaded with individual parts in position with absolute precision to prevent any rebound. Used in particular in combination with undamped stoppers.
Separating stop, undamped
For stopping and clearing pallets. Tough, economical basic design. Suitable for use wherever one or more pallets are to be accumulated at a defined position.
Separating stop, damped
For stopping and clearing pallets. For shock-sensitive, fragile parts. Pallets are gently decelerated as they arrive so that workpieces reach their final position without rebound. The forces transferred to the conveyor system are considerably reduced.
Required to slow the pallet down to a halt and dissipate the kinetic energy stored in the pallet. It consists of the damping force and the propelling force, which continues to have an effect even during the damping operation.
Friction force between the conveyor equipment and pallet. Is a function of the coefficient of friction, pallet weight and acceleration due to gravity.
