Abstract

An apparatus for inspecting a pharmaceutical cylindrical container made of glass or polymer is provided. The apparatus includes an inspection area, a handling device, and a friction wheel. The handling device has a first holder configured to hold a lateral surface of the pharmaceutical cylindrical container. The first holder includes a first support wheel and a second support wheel. The handling device moves such that the pharmaceutical cylindrical container is transferred from a first transfer position to the inspection area and from the inspection area to a second transfer position. The first holder and/or the friction wheel bring the pharmaceutical cylindrical container into contact with the friction wheel such that the pharmaceutical cylindrical container is rotated around a container longitudinal axis by rotating the first and second support wheels and/or by rotating the friction wheel.

First claim

What is claimed is:

1. An apparatus for inspecting a pharmaceutical cylindrical container made of glass or polymer, the apparatus comprising:
an inspection area;
a handling device having a first holder configured to hold a lateral surface of the pharmaceutical cylindrical container, the first holder comprising a first support wheel and a second support wheel configured so that the lateral surface of the pharmaceutical cylindrical container is supported on the first support wheel and the second support wheel in a horizontal orientation during inspection, the handling device moves such that the pharmaceutical cylindrical container is transferred from a first transfer position to the inspection area and from the inspection area to a second transfer position; and
a friction wheel, wherein the handling device and/or the friction wheel are configured to move so that the pharmaceutical cylindrical container is in contact with the friction wheel and rotated around a container longitudinal axis by the first and second support wheels and/or by the friction wheel in the inspection area,
wherein the pharmaceutical cylindrical container can be fed sync with a clock frequency of the handling device by a transportation device.

2. The apparatus of claim 1 , wherein the first support wheel has a first rotational axis and the second support wheel has a second rotational axis, a first plane being defined through the first rotational axis and the container longitudinal axis, a second plane being defined through the second rotational axis and the container longitudinal axis, wherein the first and second planes intersect at an angle in a range of 45° to less than 120°.

3. The apparatus of claim 2 , wherein the range is 65° to 75°.

4. The apparatus of claim 1 , wherein the handling device further comprises a second holder and a third holder, and wherein the first, second, and third holders are arranged on a circle with an angle of 120° to each other.

5. The apparatus of claim 1 , wherein the a transportation device moves the pharmaceutical cylindrical container to the first transfer position and receives the pharmaceutical cylindrical container at the second transfer position.

6. The apparatus of claim 5 , wherein the transportation device is a conveyor belt.

7. The apparatus of claim 5 , further comprising a first transfer device and a second transfer device at the second transfer position, the first transfer device being configured to move the container from the transportation device to the first transfer position, and the second transfer device being configured to move the container from the second transfer position to the transportation device.

8. The apparatus of claim 7 , wherein the handling device and the first and second transfer devices are configured to move at least 60 containers per minute from the first transfer position to the inspection area and from the inspection area to the second transfer position.

9. The apparatus of claim 7 , wherein the handling device and the first and second transfer devices are configured to move 80 containers per minute from the first transfer position to the inspection area and from the inspection area to the second transfer position.

10. The apparatus of claim 7 , wherein the first transfer device comprises three holding arrangements arranged on a circle with an angle of 120° to each other, the first transfer device being rotatable so that the three holding arrangements move among positions at the transportation device, the first transfer position, and a free position.

11. The apparatus of claim 7 , wherein the second transfer device comprises three holding arrangements arranged on a circle with an angle of 120° to each other, the second transfer device being rotatable so that the three holding arrangements move among positions at the transportation device, the second transfer position, and a free position.

12. The apparatus of claim 7 , wherein the first and/or second transfer devices comprise holding arrangements that are suction elements.

13. The apparatus of claim 1 , wherein the first and second support wheels comprise a material selected from a group consisting of polymer, polyoxymethylene, polyacetale, steel, and ball bearing steel.

14. The apparatus of claim 1 , wherein the handling device moves along a first axis.

15. The apparatus of claim 14 , wherein the handling device further comprises a second holder and a third holder configured to move along the first axis.

16. The apparatus of claim 14 , wherein the second holder is configured to move along a second axis and the third holder is configured to move along a third axis.

17. The apparatus of claim 16 , further comprising a cam gear and/or an electromotor configured to move the handling device along the first, second, and third axes.

18. The apparatus of claim 1 , wherein the handling device is configured to move at least 60 containers per minute from the first transfer position to the inspection area and from the inspection area to the second transfer position.

19. The apparatus of claim 1 , wherein the handling device is configured to move 80 containers per minute from the first transfer position to the inspection area and from the inspection area to the second transfer position.

20. An apparatus for inspecting a pharmaceutical cylindrical container made of glass or polymer, the apparatus comprising:
an inspection area;
a handling device having a first holder configured to hold a lateral surface of the pharmaceutical cylindrical container, the first holder comprising a first support wheel and a second support wheel, the handling device moves such that the pharmaceutical cylindrical container is transferred from a first transfer position to the inspection area and from the inspection area to a second transfer position; and
a friction wheel, wherein the handling device and/or the friction wheel are configured to move so that the pharmaceutical cylindrical container is in contact with the friction wheel and rotated around a container longitudinal axis by the first and second support wheels and/or by the friction wheel in the inspection area, wherein the handling device moves along a first axis, wherein the handling device further comprises a second holder and a third holder, wherein the second holder is configured to move along a second axis and the third holder is configured to move along a third axis, and wherein the first axis and the second axis intersect at an angle in a range of 30° to 60°, and/or wherein the first axis and the third axis intersect at an angle in a range of 30° to 60°.
