Description

Aseptic bonding equipment

The present invention relates to an aseptic joining apparatus for thermoplastic resin tubes, and in particular, for example, a tube on the patient's peritoneal catheter side used for peritoneal dialysis and a dialysate tube of a peritoneal dialysate bag are heated in a sterile state. The present invention relates to an aseptic joining apparatus for melt joining.

Peritoneal dialysis is a method in which approximately 2 liters (for adults) of dialysate is placed in the abdominal cavity using a tube embedded in the abdominal cavity of the patient, and water and waste products in the body are removed through the peritoneum. After a few hours, dialysate in the abdominal cavity is placed in a drain bag and discarded, and replaced with fresh dialysate. As a result, the dialysate was injected into the abdominal cavity surrounded by the peritoneum, and the dialysate was transferred to the dialysate through unnecessary waste and water in the peritoneal membrane while the dialysate was stored for a certain period of time. Thereafter, the dialysate can be taken out of the body to purify the blood.

The change-over switch 85 in FIG. 12 can connect the jack 84 and the battery BA, and the DC power source from the charger 86 is used for charging the battery BA. The DC power charged in the battery BA is supplied to the control unit 100.
As shown in FIG. 12, a temperature sensor 87 such as a thermistor is electrically connected to the control unit 100, and this temperature sensor 87 detects the ambient temperature (outside air temperature) around the housing 2, and controls the control unit 100. The outside air temperature information TF is supplied to 100. As a result, when the two tubes are heated based on the outside air temperature information TF and the outside air temperature is lower than a predetermined temperature, the control unit 100 lengthens the heating time of the two tubes. There is an advantage that can be processed. Further, the environmental temperature is notified to the patient by the speaker SP.

As shown in FIG. 12, the [Power switch] button 7B, [Join] button 7E, [Power] lamp 7C, [Charging] lamp 7D and [Join] on the operation panel unit 7 shown in FIG. The lamp 7F and the [wafer removal] lamp 7G are electrically connected to the control unit 100.
The speaker SP shown in FIG. 12 is electrically connected to the control unit 100 via the voice synthesis unit 88, and the speaker SP generates a voice guidance or the like that is determined in advance by a command from the control unit 100. The volume adjustment volume 22 and the voice message changeover switch 23 are electrically connected to the control unit 100. When the voice message selector switch 23 is “present”, voice guidance can be issued from the speaker SP, and when the voice message selector switch 23 is “none”, a buzzer (not shown) can be sounded.
[Close cover] lamp 8B, [Wafer cassette replacement] lamp 8C, [Wafer defective] lamp 8D, [Charge required] lamp 8E, [Inappropriate room temperature] lamp 8F, The apparatus failure] lamp 8G is lit or blinks according to a command from the control unit 100.

The solenoid 61 of the interlock 60 shown in FIG. 12 is illustrated in FIG. As illustrated in FIG. 8, for example, a photocoupler can be used as the solenoid detection sensor 89, and light 89L from the light emitting unit 89A is received by the light receiving unit 89B. When the interlock 60 of the solenoid 61 is at the lower end position 60L, the light receiving unit 89B prevents the light 89A from the light emitting unit 89A from blocking as shown by a broken line. A signal that the part 3 is not interlocked is supplied. On the other hand, when the interlock 60 of the solenoid 61 is at the upper end position 60H, the interlock 60 does not block the light 89L from the light emitting unit 89A as indicated by the solid line, so that the light receiving unit 89B includes the control unit 100. Is supplied with a “signal that the clamp lid 3 is interlocked”. Thereby, the control part 100 can grasp | ascertain the locked state or non-locking state of the clamp cover part 3. FIG.

The hall sensor 90 of the housing side clamp unit 50 illustrated in FIG. 12 is electrically connected to the control unit 100. As illustrated in FIG. 10, the distal end portion 75A of the tube detection pin 75 is a portion that receives two tubes T1 and T2, and a magnet 91 is attached to the rear end portion 75B of the tube detection pin 75. Between the rear end portion 75B of the tube detection pin 75 and the housing 2, a spring 92 for pushing up the tube detection pin 75 in the Z1 direction is disposed. When the tube T1 and the tube T2 are fitted in the fitting groove 52C between the first projection 52A and the second projection 52B in the order of the tube T1 and the tube T2, the tube T1 and the tube T2 resist the force of the spring 92 in the Z2 direction against the force of the spring 92. Since the tube detection pin 75 is lowered by pushing in, the Hall sensor 90 detects the magnetic force of the magnet 91.
Thereby, the Hall sensor 90 notifies the control unit 100 that “the two tubes T1 and T2 have been properly fitted”. If the tubes T1 and T2 are not sufficiently fitted in the fitting groove 52C, or if only one of the tubes is fitted, the Hall sensor 90 cannot detect the magnetic force of the magnet 91, The hall sensor 90 notifies the control unit 100 that “the two tubes T1 and T2 are not properly fitted”.

As illustrated in FIG. 12, the housing-side clamp unit 50 includes a micro switch 93, and the micro switch 93 is a sensor that detects the closed state of the clamp lid unit 3. As shown in FIG. 1, the micro switch 93 holds the clamp operation part 31 of the clamp lid part 3 with a finger as shown in FIG. 6 and rotates around the central axis CL in the direction of the arrow RS. 30 detects that the housing side clamp part 50 has been closed.
A wafer cassette storage unit 82 shown in FIG. 12 includes a wafer presence / absence sensor 101 and a wafer remaining amount detection sensor 102. The wafer presence / absence sensor 101 is a sensor that detects whether or not the wafer WF remains or remains in the wafer cassette WC shown in FIG. The remaining wafer detection sensor 102 is a sensor that detects how many wafers WF are left in the wafer cassette WC shown in FIG. 1, that is, the remaining number of wafers WF. For example, a photo sensor or the like can be adopted as the wafer presence / absence sensor 101 and the wafer remaining amount detection sensor 102. The tubes T1 and T2 are melted and cut by a high-temperature member, and a heating member for such use is used. As the heating member, for example, it is convenient to use a heated plate-like member, that is, a heating plate member. That is, in this embodiment, it is preferable to use a heated plate-like body in order to melt the tube, and in particular, a thin plate-like material such as a wafer WF is used.

The wafer feed unit 83 shown in FIG. 12 is a unit for linearly moving the wafer WF in the wafer cassette WC shown in FIG. 1 from the wafer cassette WC to the standby position PS1 shown in FIG. The wafer feed unit 83 shown in FIG. 12 includes a motor 103, a motor drive 104, a forward end sensor 105, an intermediate sensor 106, and a reverse end sensor 107. When the motor drive 102 receives a command from the control unit 100, the motor drive 102 drives the motor 103, so that the wafer WF moves linearly from the wafer cassette WC to the standby position PS1 shown in FIG. The forward end sensor 105, the intermediate sensor 106, and the reverse end sensor 107 detect the forward end position, the intermediate position, and the reverse end position of the wafer WF that moves linearly, and notify the control unit 100 of them.

As shown in FIG. 12, the control unit 100 is electrically connected to a wafer heater 110, a motor drive 111, a micro switch 114, a wafer current detection unit 115, a wafer voltage detection unit 116, and a fan FN. When the motor drive 111 receives a command from the control unit 100, the motor drive 111 drives the motor 500.
Wafer heater 110 heats the wafer by energization from control unit 100. During this energization, the wafer current detection unit 115 detects the wafer current value supplied to the wafer, and the wafer voltage detection unit 116 detects the wafer voltage value supplied to the wafer.

FIG. 13 shows the vicinity of the wafer cassette insertion portion 20 and the wafer cassette takeout button 21 of the housing 2 and the wafer cassette WC. The wafer cassette insertion portion 20 and the wafer cassette takeout button 21 are arranged in the wafer cassette storage unit 82 shown in FIG.
As shown in FIG. 13A, the upper surface 120 of the wafer cassette WC is provided with an arrow 21Y indicating the insertion direction. The user inserts the wafer cassette WC into the wafer cassette insertion portion 20 as shown in FIG. 13B according to the arrow 21Y. After that, when the wafers are used up and there are no more wafers in the wafer cassette WC, the user presses the wafer cassette take-out button 21 with a finger as shown in FIG. 13C, so that the empty wafer cassette WC is removed. It can be taken out from the insertion portion 20.

Next, the tube setting auxiliary tool 4 will be described with reference to FIGS. 1 to 3.
The tube set auxiliary tool 4 can be attached to the housing 2 as needed by the user. As will be described later, the tube set auxiliary tool 4 reliably performs the work of sandwiching and fixing the two tubes T1 and T2 in the housing side clamp portion 50 as illustrated in FIG. 13C. Act as a guide so you can do it. Accordingly, as shown in FIG. 13C, when the user sandwiches and fixes the two tubes T1 and T2, the user can reliably perform the work without hesitation.

As shown in FIGS. 2 and 3, the tube setting assisting tool 4 has a first side portion 135, a second side portion 136, and a back surface connecting portion 137.
As shown in FIG. 2A, the first side portion 135 has a claw portion 135A and

branch portions

135B and 135C. The claw portion 135A meshes with the vicinity of the operation panel portion 7 of the housing 2. As shown in FIG. 2B, the second side portion 136 has a claw portion 136A,

branch portions

136B and 136C, and a U-shaped receiving portion 138 for receiving a tube. The claw portion 136 A is engaged with the vicinity of the operation panel portion 7 of the housing 2. The receiving part 138 receives two tubes T1 and T2 as shown in FIG. As shown in FIG. 2B, by providing a space between the

branch portions

136B and 136C, the volume adjustment volume 22 can be exposed, and the user can easily operate the volume adjustment volume 22.

As shown in FIG. 3, the back surface connection part 137 has a first connection part 137A and a second connection part 137B. An opening 137C through which the installation member 2G is passed is formed in the first connection portion 137A. The second connecting portion 137B is provided with a protrusion 137D that matches the height of the installation member 2G. Thereby, the housing | casing 2 can be installed in the state which floated only the predetermined space | interval, for example with respect to the desk surface etc. with the four installation members 2G and the two protrusion parts 137D.

Moreover, in order to expose the exhaust opening 5 and the sound opening 6 between the first connecting portion 137A and the second connecting portion 137B, the tube set auxiliary tool 4 includes a fan FN that is an exhaust device. An opening portion 144 that opens the exhaust opening 6 and the sound opening 5 for the speaker SP is formed. Thereby, the fan FN can reliably release the gas and heat inside the housing 2 to the outside of the housing 2 through the opening 6. Also, since the voice guidance, warning sound, etc. generated by the speaker SP can be reliably output to the outside of the housing 2 through the opening 5, it is easy to hear without voice guidance, warning sound, etc.

Next, with reference to FIG. 14, an example of the positional relationship between the fan FN and the two tubes T1, T2 and the wafer WF in the housing side clamp unit 50 will be described. FIG. 17 is a side view schematically illustrating an example of the positional relationship between the fan FN, the two tubes T1 and T2 in the housing-side clamp unit 50, and the wafer WF.
As shown in FIG. 14, the wafer WF in the wafer cassette WC is sent in the Y1 direction from the wafer cassette WC shown in FIG. 17 by operating the wafer feeding unit 83 shown in FIG. It can be located at position PS1. When the wafer WF is positioned at the standby position PS1, the two contact points 131 of the wafer WF are connected to the wafer heater 110, and the wafer heater 110 generates heat when energized by a command from the controller 100. WF is heated.

In the fitting groove 52C between the first protrusion 52A and the second protrusion 52B shown in FIG. 14, two tubes T1 and T2 are stacked and fitted in the Z2 direction, and the position is substantially below the wafer WF that generates heat. Is provided with a fan FN.
When the wafer WF shown in FIG. 14 is raised from the standby position PS1 to the fusing position PS2, and the wafer WF is fusing and joining the two tubes T1 and T2, the gas of the plasticizer is supplied from the two tubes T1 and T2. Will occur. Even if the plasticizer gas is generated in this way, the plasticizer gas is opened from the exhaust opening 6 of the bottom surface portion 2A as indicated by the discharge path indicated by the thick arrow MY by the rotational drive of the fan FN. It can be reliably discharged to the outside of the body 2.

Next, the tube processing apparatus 600 will be described with reference to FIGS. 15 to 17.
FIG. 15 shows a preferred configuration example of the tube processing apparatus 600, and shows a state where the wafer WF is located at the standby position PS1 that is separated from the two tubes T1 and T2.
On the other hand, FIG. 16A shows a state in which the wafer WF is positioned at the fusing position PS2 where the wafer WF is raised toward the two tubes T1 and T2 and fusing the two tubes T1 and T2. ing. FIG. 16B shows a state in which the wafer WF is lowered after fusing the two tubes T1 and T2 and retracted to the standby position PS1. FIG. 17 is a perspective view showing a part of the mechanism of the tube processing apparatus 600.

A tube processing apparatus 600 shown in FIG. 15 includes a motor 500, a motor drive 111, a rotation operation unit 610, and a heating plate member moving unit 651. The motor drive 111 can rotate the output shaft 501 in the reverse direction from the normal rotation by driving the motor 500 according to a command from the control unit 100.
The tube processing apparatus 600 drives the motor 500 to raise the wafer WF in the Z1 direction from the standby position PS1 and position it in the fusing position PS2, or lowers the wafer WF in the Z2 direction and positions it in the standby position PS1. In order to change the function and the vertical positional relationship between the two tubes T1, T2, it has a function of rotating 180 degrees.

As shown in FIG. 15, the rotation operation unit 610 of the tube processing apparatus 600 has the following configuration.
The motor 500 is fixed to the fixing portion 502 of the housing 2. A drive gear 611 is provided on the output shaft 501 of the motor 500. The first rotation gear 621 and the second rotation gear 622 superimposed on the first rotation gear are held by bearings so that they can rotate independently of each other by the shaft portion 623. The shaft portion 623 is fixed to the fixed portion 502. The first rotation gear 621 and the second rotation gear 622 preferably have the same diameter dimension.

17A is a perspective view of the first rotating gear 621 and the second rotating gear 622 shown in FIG. 15 as viewed from the direction of the arrow V in FIG. 15, and FIG. 17B is an exploded perspective view. .
As shown in FIGS. 15 and 17, the first rotation gear 621 is engaged with the drive gear 611. As shown in FIG. 17B, the first rotating gear 621 has a columnar protruding member 630 on the side surface 621S facing the second rotating gear 622.
On the other hand, the second rotating gear 622 is formed with an arcuate guide hole 631 penetrating therethrough. As shown in FIG. 17A, the protruding member 630 is inserted into the guide hole 631 by overlapping the first rotating gear 621 and the second rotating gear 622. The projecting member 630 preferably uses a bearing, for example, so that it can move smoothly between the end 631A and the other end 631B in the guide hole 631.

As shown in FIG. 15, the second rotating gear 622 does not mesh with the drive gear 611 but meshes with the gear 55 on the outer periphery of the movable clamp unit 72. Although the structural example of the movable clamp unit 72 is also illustrated in FIG. 7, the first tube pressing member 35 and the second tube pressing member 53 each have a semi-cylindrical shape. As shown in FIG. 1, when the clamp lid 3 is closed, the second tube pressing member 53 shown in FIG. 7 and the first tube pressing member 35 on the clamp plate 30 side overlap. For this reason, the 1st tube pressing member 35 and the 2nd tube pressing member 53 comprise the cylindrical member which can accommodate and hold | maintain so that tube T1 and tube T2 may not move.

Next, the heating plate member moving portion 651 of the tube processing apparatus 600 has the following configuration.
Another shaft portion 650 is rotatably held by the fixing portion 502 shown in FIG. A moving part 651 of a heating plate member is fixed to the tip part of the shaft part 650. The heating plate member moving portion 651 includes a moving gear 652, a cam 653 fixed to the moving gear 652, and a wafer holder 660.
The moving gear 652 meshes with the drive gear 611. The cam 653 is fixed to the moving gear 652. The cam 653 is fixed to one side surface of the movement gear 652 so that the center axis 653L of the cam 653 is eccentric with respect to the rotation center axis 652L of the movement gear 652. Thereby, the copying surface 670 of the cam 653 moves eccentrically in the Z1 and Z2 directions when the moving gear 652 rotates. Wafer WF is held by wafer holder 660.

The wafer holder 660 is a holding member for a heating plate member for holding the wafer WF upright along the Z direction. The wafer holder 660 has a bearing 661 as a driven member or a copying member. The bearing 661 is placed on the copying surface 670 of the cam 653. In FIG. 15, the wafer WF held by the wafer holder 660 is positioned at the standby position PS1 shown in FIG. On the other hand, in the state shown in FIG. 16A, the wafer WF held by the wafer holder 660 is positioned at the fusing position PS2 at the uppermost end position shown in FIG.

The shape of the copying surface 670 of the cam 653 is a shape that can be operated as follows. When the moving gear 652 and the cam 653 of the moving part 651 of the heating plate member rotate forward about the rotation center shaft 652L, the wafer WF held by the wafer holder 660 is moved from the standby position PS1 shown in FIG. Ascending stroke SL can be raised to fusing position PS2 at the uppermost end position shown in FIG. Thereafter, when the moving gear 652 and the cam 653 of the moving part 651 of the heating plate member rotate in the reverse direction about the rotation center shaft 652L, the wafer WF held by the wafer holder 660 is shown in FIG. From the fusing position PS2, it is possible to move down to the standby position PS1 shown in FIG.

Next, using the above-described aseptic joining apparatus 1, the operations of heating and melting the two tubes T1 and T2 shown in FIG. 5 and pressurizing and joining are mainly shown in FIGS. 15 to 17 and 18 to 18. This will be described with reference to FIG.
FIG. 18 is a diagram showing how the tube T1 and the tube T2 are fitted to the housing side clamp portion 50 side, and FIG. 19 shows the joint portion formed by the previous joining of the tube T2 at the tip of the positioning projection 140. It is a figure which shows a mode that it pushes together. FIG. 20 is an explanatory diagram showing the procedure of aseptic heating joining of the two tubes T1 and T2.
As shown in FIG. 1, the interlock 60 has already been retracted into the housing 2. When the user grasps the clamp operation part 31 of the aseptic joining apparatus 1 shown in FIG. 1 and lifts it in the direction of the arrow RT, the clamp lid part 3 is separated from the case side clamp part 50 as shown in FIG. The clamp part 50 can be opened.

Next, a tube T1 shown in FIG. 18A is prepared, and a joining portion C1 of the tube T1 is a portion to be joined. As shown in FIG. 18B, the tube T1 is fitted in the fitting groove 51C of the first tube sandwiching portion 51 and the fitting groove 52C of the second tube sandwiching portion 52 in the X1 direction. . In this case, the portion of the tube T1 on the connector CT side is disposed on the U-shaped receiving portion 138 of the tube setting auxiliary tool 4, and the connector CT is positioned outside the receiving portion 138.
In FIG. 18C, another tube T2 is arranged in the X2 direction in a state of being stacked on the upper side of the tube T1. The tube T2 has a joint portion 141 formed at the time of the previous joint, and the cross section of the joint portion 141 is circular.

In FIG. 19A, the tube T2 is fitted in the fitting groove 51C of the first tube sandwiching portion 51 in the X2 direction so that the previous joining portion 141 of the tube T2 is aligned with the tip of the protrusion 140. The second tube sandwiching portion 52 is fitted into the fitting groove 52C.
Accordingly, as shown in FIG. 19B, the tube T2 is stacked on the tube T1 along the Z1 direction, and the tubes T1 and T2 are securely fitted in the

fitting grooves

51C and 52C in the direction of the arrow RZ. Can be pushed into and fixed.

Next, the user grasps the clamp operation part 31 shown in FIG. 6, rotates the clamp lid part 3 in the closing direction along the RS direction, and closes the casing-side clamp part 50 by the clamp lid part 3. As a result, as shown in FIG. 20A, the two tubes T1 and T2 having the same thickness are sandwiched between the first tube sandwiching portion 51 and the accommodating member 37, and the second tube is sandwiched. It is sandwiched between the portion 52 and the accommodating member 36. Moreover, the wafer WF is moved from the wafer cassette WC of FIG. 14 to the standby position PS1 below the tubes T1 and T2, as shown in FIGS. 15 and 20B. For this reason, the wafer WF shown in FIG. 14 is heated to, for example, about 300 ° C. by the heating of the wafer heater 110.

Here, as shown in FIG. 15, in the state where the wafer WF is positioned at the standby position PS1, the tubes T1 and T2 are overlapped so that the tube T1 is below the tube T2 in the movable clamp unit 72. Is held. That is, the tube T1 is on the lower side and the tube T2 is on the upper side. Moreover, the columnar protruding member 630 of the first rotating gear 621 is positioned at one end 631A of the arcuate guide hole 631 of the second rotating gear 622.

When the control unit 100 shown in FIG. 15 gives a command to the motor drive 111 and drives the motor 500, the drive gear 611 of the output shaft 501 is used to move the first rotation gear 621 and the heating plate member moving unit 651. The rotational force is transmitted to the gear 652 at the same time.
As a result, the first rotation gear 621 starts rotating, but the second rotation gear 622 does not rotate. That is, the columnar projection member 630 of the first rotation gear 621 moves from the end 631A of the guide hole 631 of the second rotation gear 622 toward the end 631B, and therefore the first rotation gear 621 starts to rotate. However, the second rotation gear 622 does not start rotating.
As described above, during the period TS1 in which the cylindrical projection member 630 of the first rotation gear 621 is moving from the end 631A of the guide hole 631 of the second rotation gear 622 toward the end 631B, the first Since no rotational force is transmitted from the rotary gear 621 to the second rotary gear 622, the second rotary gear 622 and the movable clamp unit 72 do not rotate.

On the other hand, since the rotational force is also transmitted to the first rotating gear 621 and the moving gear 652 of the heating plate member moving portion 651 shown in FIG. 15, the cam 653 rotates eccentrically with respect to the rotation center shaft 652L. Since the bearing 661 of the wafer holder 660 is placed on the copying surface 670 of the cam 653, the wafer WF held by the wafer holder 660 is moved from the standby position PS1 shown in FIG. Ascending stroke SL rises to fusing position PS2 at the upper end position. Accordingly, as shown in FIG. 20C, the heated wafer WF can be melted by passing through the two tubes T1, T2 having the same thickness upward from the lower side.

As described above, the period TS2 until the wafer WF reaches the fusing position PS2 at the uppermost end position shown in FIG. 16A from the standby position PS1 shown in FIG. 15 is the cylindrical shape of the first rotating gear 621 already described. The protruding member 630 is set to be the same or slightly shorter than the period TS1 in which the protruding member 630 moves from the end 631A of the guide hole 631 of the second rotation gear 622 toward the end 631B. Thereby, when the wafer WF is positioned at the fusing position PS2, or after being positioned, the movable clamp unit 72 is always rotated by 180 degrees.

Further, when the drive gear 611 shown in FIG. 16A further rotates the first rotation gear 621, the columnar protruding member 630 of the first rotation gear 621 becomes the end of the guide hole 631 of the second rotation gear 622. It hits part 631B. For this reason, since the rotational force is transmitted from the first rotation gear 621 to the second rotation gear 622, the second rotation gear 622 and the movable clamp unit 72 start to rotate.
Accordingly, when the first tube pressing member 35 and the second tube pressing member 53 of the movable clamp unit 72 in FIG. 16A are rotated 180 degrees while holding the tubes T1 and T2, the lower tube becomes a tube. T2 and the upper tube becomes the tube T1. At this time, the wafer WF is still in the fusing position PS2 as shown in FIGS. 20 (C) and 16 (A).

Thereafter, as shown in FIGS. 16A to 16B, when the output shaft 501 of the motor 500 is reversed, the wafer WF is lowered in the Z2 direction from the fusing position PS2 and returned to the standby position PS1. At this time, the projecting member 630 of the first rotating gear 621 returns from the end 631B toward the end 631A in the guide hole 631, so that even if the first rotating gear 621 rotates, the second rotating gear 621 rotates. 622 does not rotate. Thereby, the movable clamp unit 72 does not rotate any more and can maintain the state shown in FIG.
Then, as shown in FIG. 20D, the portions of the tubes T1 and T2 on the side rotated 180 degrees are pushed in the X2 direction. As a result, as shown in FIG. 16B, one end 811 of the upper tube T1 fused and rotated 180 degrees by the wafer WF and one end 911 of the lower tube T2 are completely rotated. The other end portion 912 of the upper tube T2 that is not connected and the other end portion 812 of the lower tube T1 are respectively pressure-bonded to form a joint portion 950. Thereafter, when the tubes T1 and T2 are cooled, the aseptic joining is completed.

The used wafer WF is discharged to the used wafer W take-out section 58 as shown in FIG. 1 by the operation of the wafer feeding unit 83 shown in FIG. Thereby, the user can pick up the used wafer WF with a finger and take it out.
After that, when the user grasps the clamp operation unit 31 shown in FIG. 1 again and lifts it in the direction of the arrow RT, the clamp lid 3 is separated from the housing side clamp unit 50 as shown in FIG. The user removes and separates the tubes T1 and T2 after being joined as shown in FIGS. 20E and 20F from the housing-side clamp 50. As described above, as shown in FIG. 20 (F), the tube T1 on the dialysate bag BL side shown in FIG. 5 and the tube T2 on the user M side can be joined aseptically and simply. it can.
As described above, when the wafer WF in the wafer cassette WC shown in FIG. 1 moves in the Y1 direction from the wafer cassette WC as shown in FIG. 17 and is positioned at the standby position PS1 shown in FIG. The two contact points 131 of the WF are connected to the wafer heater 110, and the wafer WF generates heat when the wafer heater 110 generates heat according to a command from the control unit 100.

As described above, as shown in FIGS. 15 to 16A, when the wafer WF starts to rise in the Z1 direction from the standby position PS1 to the fusing position PS2, the second rotating gear 622 is in the first position. Since it does not rotate regardless of the rotation of the one-rotation gear 621, the tubes T1 and T2 of the movable clamp unit 72 do not rotate. That is, the tubes T1 and T2 cannot be rotated until the wafer WF completely reaches the highest fusing position PS2. When the wafer WF completely reaches the highest fusing position PS2, the second rotating gear 622 rotates together with the first rotating gear 621, so that the movable clamp unit 72 can rotate the tubes T1 and T2 by 180 degrees. .

Incidentally, as shown in FIG. 10, two tubes T1 and T2 are fitted in the fitting groove 52C between the first projection 52A and the second projection 52B, and a fan is formed below the heat generating wafer WF. FN is arranged. When the wafer WF shown in FIG. 14 is raised from the standby position PS1 to the fusing position PS2, and the wafer WF is fusing and joining the two tubes T1 and T2, the gas of the plasticizer is supplied from the two tubes T1 and T2. Will occur. This plasticizer gas can be reliably discharged from the opening 6 of the bottom surface 2A to the outside of the housing 2 by the rotation of the fan FN, as indicated by the thick arrow MY. Since the fan FN and the opening portion 6 for the fan FN are arranged not on the side surface portion of the housing 2 but on the bottom surface portion of the housing 2, the fan FN and the opening portion on the side surface portion of the housing 2 are provided. Thus, the plasticizer gas is not directly ejected to the side. For this reason, even if a plastic product is placed in the vicinity of the housing 2, the plasticizer gas is not directly blown against the plastic product, so that the plastic product is not adversely affected such as a partial melting.

The aseptic joining apparatus 1 of the embodiment of the present invention melts the first tube and the second tube with the wafer WF as a heating plate member in a state where the first tube T1 and the second tube T2 are fixed, It is an aseptic joining apparatus that replaces and joins the melted end of the first tube and the melted end of the second tube. The aseptic joining apparatus 1 includes a motor 500 having a drive gear on an output shaft, a control unit 100 that commands driving of the motor, a movable clamp unit 72 that holds the first tube and the second tube in an overlapping manner, and driving of the motor. By rotating the gear, the heating plate member is moved between the standby position PS1 separated from the first tube and the second tube, and the fusing position PS2 for fusing the first tube and the second tube, whereby the first tube By rotating the movable clamp unit 72 in a state where the heating plate member is positioned at the fusing position by rotating the heating plate member moving portion 651 for fusing the second tube and the driving gear of the motor, It has the rotation operation part 610 which replaces the melted end part of the first tube and the melted end part of the second tube.
Thus, if one motor is used, the fusing of the first tube and the second tube due to the movement of the heating plate member and the end of the fused first tube and the end of the second tube can be interchanged. It is possible to reduce weight and size, and promote cost reduction.

The moving part 651 of the heating plate member has a moving gear that meshes with the driving gear of the motor, and a cam that rotates with the moving gear to move the heating plate member between the standby position and the fusing position. Thereby, the heating plate member can be reliably moved between the standby position and the fusing position by using the moving gear and the cam.

A wafer holder 660 is provided as a holding member for holding the heating plate member. This holding member has a bearing 661 that is a copying member that follows the copying surface 670 on the outer periphery of the cam 653, and the cam member that rotates the copying member. The plate member for heating is moved between the standby position PS1 and the fusing position PS2 by linearly moving along the copying surface. Thereby, the heating plate member can be smoothly linearly moved between the standby position and the fusing position by using the copying member while the heating plate member is held by the holding member.

The rotation operation unit 610 is integrated with the first rotation gear with the first rotation gear 621 meshed with the drive gear of the motor and the first rotation gear being held coaxially with the heating plate member positioned at the fusing position. By rotating and rotating the movable clamp unit, it has the 2nd rotation gear 622 which replaces the melted end part of the 1st tube, and the melted end part of the 2nd tube. Thereby, in a state where the heating plate member is positioned at the fusing position, the melted end portion of the first tube and the melted end portion of the second tube can be switched, so that the first tube is blown in a sterile state. The end and the melted end of the second tube can be interchanged.

The first rotating gear 621 has a protruding member 630, and the second rotating gear 622 has a guide hole 631 for guiding the protruding member, and the first rotating gear rotates relative to the second rotating gear. Thus, when the protruding member is guided along the guide hole and hits the end of the guide hole, the second rotating gear rotates in the same direction together with the first rotating gear, and the heating plate member is positioned at the fusing position. By rotating the movable clamp unit in a state where the first tube is melted, the melted end of the first tube and the melted end of the second tube are exchanged. As a result, the heating plate member is positioned at the fusing position by delaying the start of rotation of the second rotating gear with respect to the rotating operation of the first rotating gear of the rotation operation unit, so that the first tube was blown in a sterile state. The end and the melted end of the second tube can be interchanged.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims. A part of each configuration of the above embodiment can be omitted, or can be arbitrarily combined so as to be different from the above.
The aseptic joining device of the present invention is not only used for aseptic joining of two equal-sized tubes for exchanging peritoneal dialysate. The aseptic joining apparatus of the present invention can also be used to automatically join two tubes of the same diameter used for blood transfusion in aseptic conditions, for example, and contaminate bacteria when joining the two tubes. Therefore, the sterility of the blood components in the tube and bag can be maintained.
