Abstract
A buckle pivotally arranged in a movable clamp 12 of a first tube holder 1 is attached with play to a buckle 120 pivotally arranged in a movable clamp 82 of a second tube holder 2. When tubes are held in the first and second tube holders 1 and 2, release of the tubes from the holders 1 and 2 is prevented by a movement of a plunger 203 in correspondence of excitation and demagnetization of a solenoid 202 for a predetermined period of operation of the apparatus after holding the tubes (i.e., for a period required from the locking of the buckle 120 until the completion of moving-down of a wafer holder).
Claims6
A tube connecting apparatus including:
- a first tube holder provided with a pair of holding members for holding a plurality of flexible tubes, the holding members including a fixed member and a movable member;
- a second tube holder provided with a pair of holding members for holding the plurality of flexible tubes, the holding members including a fixed member and a movable member;
- cutting and connecting means for heating and melting the plurality of flexible tubes held in the first tube holder and the second tube holder to cut the tubes by a heated cutting plate which is moved between the first tube holder and the second tube holder and to connect the tubes cut by the cutting plate by contacting cut end faces of the cut tubes held in the first tube holder with those of the cut tubes held in the second tube holder, the cut tubes to be connected being parts of originally different tubes;
- and
- joining members for integrally supporting the movable member of the first tube holder and the movable member of the second tube holder so that the movable members are moved together and connected to the corresponding fixed members,
- the joining members being arranged so that one of the tube holders is movable with respect to the other tube holder when the movable members are connected to the corresponding fixed members of the tube holders.
