## Abstract

A method for stopping a discrete product that is fed by a continuous conveyor along a feed path in a feed direction to a stop location, the method including the steps: initially moving a stop at the stop location from a reset position outside of the feed path into the feed path so that the discrete product contacts the stop and moves the stop in the feed direction by a damping length wherein an impulse of the discrete product is dissipated by a fluid flowing through a throttle element; subsequently removing the stop from the feed path and moving the stop by the damping length against the feed direction back into the reset position; and pivoting the stop from the reset position into the feed path and pivoting the stop from the feed path into the reset position about the feed direction.

## Claims

### Claim 1

A method for stopping a discrete product that is fed by a continuous conveyor along a feed path in a feed direction to a stop location, the method comprising the steps:
initially moving a stop at the stop location from a reset position outside of the feed path into the feed path so that the discrete product contacts the stop and moves the stop in the feed direction by a damping length wherein an impulse of the discrete product is dissipated by a fluid flowing through a throttle element;
subsequently removing the stop from the feed path and moving the stop by the damping length against the feed direction back into the reset position; and
pivoting the stop from the reset position into the feed path and pivoting the stop from the feed path into the reset position about the feed direction.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the stop is pivoted in one direction of rotation from the reset position into the feed path and in an opposite direction of rotation from the feed path into the reset position about the feed direction.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the stop is pivoted by a pivot angle from the reset position into the feed path.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the stop is moved back by the damping length after being removed from the feed path by the discrete product traveling over the stop location.

### Claim 5

A pallet stopper for stopping a discrete product at stop location of a feed path along which the discrete product is fed by a continuous conveyor in a feed direction, the pallet stopper comprising:
a stop;
a drive by which the stop is movable from a reset position outside of the feed path into the feed path and removable from the feed path;
a throttle element wherein an impulse of the discrete product that impacts the stop and displaces the stop in the feed direction by a damping length is dissipated by a fluid flowing through a throttle element; and
a reset drive by which the stop is movable about the damping length against the feed direction back into the reset position,
wherein the stop is pivotable by the drive about the feed direction.

### Claim 6 (depends on 5)

The pallet stopper according to claim 5, wherein the drive is a motor.

### Claim 7 (depends on 5)

The pallet stopper according to claim 5, wherein a damping element includes a piston that is movable in a damping cylinder that is filled with a fluid.

### Claim 8 (depends on 7)

The pallet stopper according to claim 7, wherein the piston is mechanically connected with the stop so that the piston is moved against the feed direction when the stop is moved in the feed direction.

### Claim 9 (depends on 5)

The pallet stopper according to claim 5, wherein the stop is made from steel.

### Claim 10 (depends on 5)

The pallet stopper according to claim 5, wherein the reset drive includes a reset stop that is actuated when the discrete products runs over the stop location.
