Abstract

A device and a corresponding method for discharging products, particularly product containers such as bottles from a transport path by means of one or more discharge segments, wherein the or each discharge segment comprises a carriage and a discharger, and the discharger can effect discharge of the product by a deflection. The or each discharge segment includes a second carriage, each of the two carriages mounted on a guide, and the discharger and the carriages are mechanically connected to one another such that the relative distance of the carriages from one another determines the deflection of the discharger.

Claims

1. A device for discharging products, from a transport path by means of one or more discharge segments, wherein the or each discharge segment comprises a carriage and a discharger, and said discharger can effect a discharge of the product by way of a deflection,

the or each discharge segment comprising a second carriage, wherein each of the two carriages is mounted on a guide to be movably supported and the discharger and the carriages are mechanically connected to one another such that the relative distance of the carriages from one another determines the deflection of the discharger, wherein the guide has a closed geometry.

2. The device according to claim 1, the carriages and the guide forming a linear motor.

3. The device according to claim 1, and a plurality of discharge segments are provided that are movable independently of one another.

4. The device according to claim 1, and the two carriages of the or each discharge segment are mounted on one and the same guide or on different guides.

5. The device according to claim 1, the or each discharge segment having a mechanical connection of the discharger and of the two carriages such that at least one rigid connection rod is respectively connected via hinges to both the discharger and a respective one of the two carriages.

6. The device according to claim 1, the or each discharge segment having a mechanical connection of the discharger and of the carriages via a scissor arm.

7. The device according to claim 1, the or each discharge segment having a mechanical connection of the discharger and of the two carriages such that the discharger and the two carriages are connected by non-rigid connection elements, for instance by a chain, which translate the changes in the relative position of the two carriages relative to one another into a change in the deflection of the discharger.

8. The device according to claim 1, the or each discharge segment having a mechanical connection of the discharger and of the two carriages such that:

a movement of the discharger relative to one of the two carriages takes place only in a direction perpendicular to the movement direction of the products of the transport path,

or a movement of the discharger relative to the center of the two carriages takes place only in a direction perpendicular to the movement direction of the products of the transport path.

9. The device according to claim 1, the guide comprising:

a discharge path which is arranged along the movement direction of the products in the transport path and on which at any place the product to be discharged can be discharged by the discharge segment;

a return path on which the carriages are decelerated and on which the movement of the carriages can be opposite to the movement direction of the products in the transport path; and

a rest position at which discharge segments can be arranged one after the other.

10. The device according to claim 1, and a proximity switch that commands provision of a discharge segment;

and

a control device that determines the acceleration and speed of the carriages on the discharge path from the speed of the product to be discharged in the transport path.

11. The device according to claim 1, the one or plural discharge segments are:

able to move on the discharge path at the same speed as the products in the transport path.

12. The device according to claim 1, the products to be discharged being product containers.

13. The device to according to claim 12, the product containers being bottles.

14. A method for discharging products from a transport path by means of one or plural discharge segments, wherein the or each discharge segment comprises a carriage and a discharger, and the discharger can effect the discharge of the product by a deflection comprising effecting the deflection of the discharger by way of a mechanical connection by changing the relative position of a second carriage with respect to the first carriage, wherein the first and second carriages are moved along a guide having a closed geometry.

15. The method according to claim 14, including one or more of the following:

effecting the discharge by discharge segments which are movable independently of one another;

driving the discharge segments by linear motors;

effecting the discharge of a respective product by exactly one discharge segment;

carrying out the discharge from the transport path onto one or plural discharge paths;

effecting the provision of one or plural discharge segments by a proximity switch; and

effecting the control of the discharge segment(s) by a control device.
