The size, type and other properties of known caps can then optionally be determined using a table and the device can be controlled accordingly.
  • the light source is a laser and the deflection means is a rotating polygon mirror during operation, which pivots the light beam during operation by an angular range ⁇ , particularly precise detection of the objects is possible.
  • the optical system has a basic body made of a refracting material, which has a lens-shaped, in particular aspherical, curved region facing the measuring path, into which the light beam can enter the deflecting means and at least from part of the angular region ⁇ the sensor means is steered.
  • the sensor means can then be a photodiode, an avalanche photodiode or the like.
  • the cuddle area can also be sensed by a CCD line.
  • the sensor means is arranged inside the base body or directly on an outer surface of the base body, there is good optical contact with the optical system.

  • the device in practice if, during operation, the light beam initially falls on the second sensor means at the beginning of the winding area, as a result of which the electrical signal receives a start pulse, then the light beam is pivoted over the measuring path and is deflected by the deflection means onto the first sensor means , whereby the electrical signal receives a light pulse that lasts for the duration of the pivoting, and an object possibly present on the measurement path superimposes a light pulse on the light pulse by a light interruption corresponding to the deflected region of the worm.

  • FIG. 1 shows a detection unit for an automatic sample opening device in a perspective view obliquely from above.
  • the detection unit comprises a light source 1, a polygon mirror 2, a drive motor 3 and a housing 4. These components are shown in an exploded view in the direction of an axis of rotation 5 of the drive motor 3.
  • the model 22BT-6A from PORTESCAP SA, Switzerland, is suitable as the drive motor 3.
  • a receiver unit with a base body 6, an aspherical lens section 7, a first sensor means 8 and a second sensor means 9 is illustrated.
  • the sensor means 8 and 9 each lie in the end section of a channel 10, which is provided for the laying of connecting lines, not shown, of the sensor means 8 and 9.
  • the polygon mirror 2 is seated with a central inner bore 11 on a hub section 12 of the motor 3.
  • the polygon mirror 2, the drive motor 3 and the light source 1 are fixedly arranged in a mounting space 13 of the mounting device 4.
  • the light source 1 is arranged in such a way that when the polygon mirror 2 rotates about its longitudinal axis 5, which coincides with the axis of rotation of the motor 3, it first forms a first light beam 15 which falls directly on the second sensor means 9. Then, as a result of the rotation of the polygon mirror 2, the light beam is pivoted through an angle in total, a light beam 16 first falling on a lateral region of the cylindrical lens 7 and being deflected from there onto the first sensor means 8.
  • the light beam 17 is reflected onto the opposite end of the cylindrical lens 7, from where it is also deflected onto the first sensor means 8.
  • the cylindrical lens 7 is designed such that the incident light falls on the first sensor means 8 in all angular ranges between the light beam 16 and the light beam 17, so that it is continuously illuminated during the pivoting by the angle enclosed by the light beams 16 and 17.
  • the light coming from the light source 1 falls on an adjacent polygon surface of the polygon mirror 2, so that the angle from the light beam 15 to the light beam 17 is pivoted again, again briefly the second sensor means 9 and continuously the first sensor means 8 is exposed to light.
  • the sensor means thus first emit a short light pulse from the second sensor means 9 at the start of the swiveling process via the angle ⁇ via their connecting lines, whereupon a continuous signal from the first sensor means 8 is present for the entire swiveling period between the light beams 16 and 17 .
  • the pulse of the second sensor means 9 is used both as a start pulse for the signal and for speed control of the drive motor 3.
  • a measuring path 20 is formed in the angular region ⁇ and is arranged between the light beams 16 and 17.
  • the detection device described so far is used in automatic opening devices for sample containers, in particular for blood samples and the like.
  • the swivel range ⁇ of the light beam and in particular the measuring path 20 is built into the path of the sample container from a conveying device to an opening device in the form of a cap twister or the like.
  • a container to be opened is then moved in a first direction I from below through the measuring path 20 to the cap extractor.
  • the upper region of the container is swept by the light beam along the measuring path 20 and the signal, which is usually continuously bright and is present at the first sensor means 8, is interrupted for the time required for the light beam to pass over the container.
  • the angular velocity of the light beam over the angular range ⁇ is known. From the angular velocity and the distance of the measuring path 20 from the axis 5, the duration of the signal interruption of the first can Sensor means 8, the width of the object in the area of the measurement path 20 can be determined. With a known number of possible variants of the sample container, the type of object can then be determined on the basis of the interruption period of the signal and a corresponding table.
  • the cap of the container to be opened can be swept several times by the light beam 16, 17, so that in addition to the unique width determination, a kind of height profile of the object can be created in a second dimension.
  • the type can then be determined more reliably.
  • Knowledge of the type of container can be used, for example, to control the end position of the lifting movement I as a function of the vertical length of the container. It is not necessary to determine the end position of the stroke movement in the direction I as a stop.
  • the control of the subsequent cap twister can be controlled depending on the type of container so that the cap identified in each case can be turned off particularly well.
  • the device works with relatively few components and is therefore simple and reliable in operation. Also the structure of the receiving unit with the two sensor means 8 and 9 is relatively simple and requires little maintenance. In addition, generated signals are of a relatively simple structure and can be reliably analyzed without great expenditure on equipment.
  • this detection unit in a device according to the invention results in great reliability, great flexibility in the design of the control and, last but not least, an inexpensive solution.
