Abstract

A hold-transfer system for extraction containers has a main body and a cassette detachable from the main body. The cassette has holding devices for holding extraction containers in an upright position, an endless traveling member carrying the holding devices arranged in a row, and a driving rotor and a driven rotor engaging the endless traveling member about perimeters thereof. The endless traveling member has rotatable support member for rotatably supporting the holding devices with lower portions of the holding devices protruding below the rotatable support members and accessible from beneath the cassette. The main body has a driving motor for driving the driving rotor and an identifying device, installed at a reading position relative to a specified position for an extraction, for identifying an identification mark associated with one of the extraction containers. The identifying device includes a reading device for reading the identification mark and a rotating mechanism for engaging and rotating the lower portion of the holding device to rotate the extraction container to expose the identification mark to the reading device.

Claims

1. A hold-transfer system for extraction containers comprising:

a main body and a cassette detachable from said main body;

said cassette having holding means for holding extraction containers in an upright position, an endless traveling member carrying said holding means arranged in a row, a driving rotor and a driven rotor engaging said endless traveling member about perimeters thereof;

said endless traveling member having rotatable support means for rotatably supporting said holding means with a lower portion of said holding means protruding below said rotatable support means and accessible from beneath said cassette;

said main body having driving means for driving said driving rotor and an identifying means, installed at a reading position relative to a specified position for an extraction, for identifying an identification mark associated with one of said extraction containers; and

said identifying means including a reading means for reading said identification mark and a rotating means for engaging and rotating said lower portion of said holding means to rotate said extraction container to expose said identification mark to said reading means.

2. A hold-transfer system according to claim 1 wherein said container includes an adaptor insertable into said holding means and a container proper inserted into said adaptor.

3. A hold-transfer system for extraction containers according to claim 2, wherein there are a plurality of configurations of said adapters applicable to variously shaped container propers.

4. A hold-transfer system for extraction containers according to claim 2, wherein said identification marks are affixed on said adapter.

5. A hold-transfer system for extraction containers according to claim 1 or 2, further comprising at least another cassette identical to said first cassette for said main body.

6. A hold-transfer system for extraction containers according to claim 1 or 2, wherein said driving means drives intermittently so as to transfer and stop repeatedly for each one of said extraction containers held by said endless traveling member.

7. A hold-transfer system for extraction containers according to claim 6, wherein said identifying means operates while said intermittent driving means stops.

10. The hold-transfer system for extraction containers according claim 1 wherein one of said driving and driven rotors includes a detent means for providing a bias to retain said holding means at positions aligned with said reading position and said specified position, said positions being space apart by a one pitch distance equal to a center to center distance of said holding means.

11. The hold-transfer system for extraction containers according claim 10 wherein said detent means includes a ball plunger assembly and a dividing hole member functionally coupled to said one of said driving and said driven rotors and said cassette.

12. The hold-transfer system for extraction containers according to any one claims 1, 8 or 9 further comprising a base plate rotatable supporting said driving rotor and said driven rotor and said rotatable support means have a leg member with a roller engaging said base plate to support said rotatable support means.

8. A hold-transfer system for extraction containers comprising:

a main body and two or more cassettes detachable from said main body;

each of said two or more cassettes having holding means for holding extraction containers in an upright position, an endless traveling member carrying said holding means arranged in a row, a driving rotor and a driven rotor engaging said traveling member about perimeters thereof;

said endless traveling member having rotatable support means for rotatably supporting said holding means with a lower portion of said holding means protruding below said rotatable support means and accessible from beneath said cassette;

said main body having driving means for driving said driving rotor and an identifying means, installed at a reading position relative to a specified position for an extraction, for identifying an identification mark associate with one of said containers;

said identifying means including a reading means for reading said identification mark and a rotating means for engaging and rotating said lower portion of said holding means to rotate said extraction container to expose said identification mark to said reading means; and

said containers including variously shaped container propers and a plurality of types of adapters which are applicable to said variously shaped container propers and insertable into said holding means.

9. A hold-transfer system for extraction containers comprising:

holding means for holding extraction containers in an upright position, an endless traveling member carrying said holding means arranged in a row, a driving rotor and a driven rotor engaging said endless traveling member about perimeters thereof;

said endless traveling member having rotatable support means for rotatably supporting said holding means with a lower portion of said holding means protruding below said rotatable support means;

driving means for driving said driving rotor and an identifying means, installed at a reading position relative to a specified position for an extraction, for identifying an identification mark associated with one of said extraction containers; and

said identifying means including a reading means for reading said identification mark and a rotating means for engaging and rotating said lower portion of said holding means to rotate said extraction container to expose said identification mark to said reading means.
