As shown in FIG. 1, the test tube rack 3 has a structure in which a column 12 is erected from each of the four corners of a rectangular lower frame 11 and a support plate 13 is horizontally attached to the upper end of the column 12. A spacer 14 is also provided between the columns 12 for reinforcement. The support plate 13 is formed with test tube holes 15 for accommodating a predetermined number of test tubes 5 in the vertical and horizontal directions. Each test tube hole 15 is fitted with an upper end portion of a test tube holder 16 made of an elastic material such as silicon rubber, for example.

  As shown in FIG. 2, the test tube holder 16 has a rack groove (circumferential groove) 17 formed on the outer periphery of the upper end thereof, and is elastically fitted into the test tube hole 15 formed in the support plate 13 of the test tube rack 3. The bottom of the test tube holder 16 is held in a suspended state that is a free end that can move freely. A test tube holding protrusion 18 is formed on the upper inner surface of the test tube holder 16 so as to be held in close contact with the upper portion of the test tube 5. The test tube holding projection 18 serves as a support point when the bottom of the test tube is vibrated. A hole 19 is provided in the lower bottom portion of the test tube holder 16. This hole 19 functions as an air vent hole through which air is circulated in order to make the inside of the holder have the same pressure as the outside air when the test tube 5 is taken in and out. The hole 19 also functions as a drainage hole for draining the liquid accumulated in the holder after the test tube rack 3 is put into the high-pressure steam sterilizer after use.

  As shown in FIG. 3, the test tube 5 is inserted and held in the test tube holder 16 mounted in each test tube hole 15 aligned in the vertical and horizontal directions of the test tube rack 3. As shown in FIG. 4, since the test tube 5 is inserted and held in the test tube holder 16 supported in the suspended state, the suspended state in which the bottom of the test tube 5 is also a free end that can move freely. Held in. In this way, a large number of test tubes 5 are held in a state where they are aligned vertically and horizontally with respect to the test tube rack 3, and the test tube rack 3 is installed on the test tube stirring mechanism portion 7.

  Next, the test tube stirring mechanism part 7 in the test tube stirring apparatus 1 of this Embodiment is demonstrated using FIGS. The test tube agitation mechanism unit 7 shown in FIG. 5 is installed on the fixed plate 31 and includes rack positioning pins 29 that protrude from the upper end surfaces of the columns 30 that stand on the four corners of the fixed plate 31. The test tube rack 3 is positioned directly above the test tube stirring mechanism portion 7 by inserting it into positioning holes (not shown) at the four corners of the lower frame 11 of the test tube rack 3.

  The test tube stirring mechanism unit 7 can move in the front-rear (vertical) direction on the fixed plate 31. The front-rear direction drive motor M1 rotates the pinion gear 32, and moves the rack 33 meshing with the pinion gear 32 and the stirring mechanism base 34 to which the rack 33 is fixed in the front-rear direction, thereby stirring the test tube. The entire mechanism unit 7 can be moved in the front-rear direction along the guide rail 35. These longitudinal drive motor M1, pinion gear 32, rack 33, and agitation mechanism base 34 constitute a longitudinal drive mechanism 27.

  As shown in FIGS. 5 and 7, two guide shafts 36 are fixed vertically on the stirring mechanism base 34, and are positioned at the apex of an isosceles triangle with respect to these two guide shafts 36. A rod screw 37 is raised. The lower end of the bar screw 37 is coupled to the output shaft of a vertical movement drive motor M2 disposed below the base 34, and is rotated. The guide shaft 36 is inserted into a slide short tube 39 fixed to the front right corner and the front left corner of the vibration mechanism base plate 38, and the bar screw 37 is connected to an inner screw tube 40 fixed to the rear center portion of the vibration mechanism base plate 38. The vibration mechanism base plate 38 is horizontally supported by the guide shaft 36 and the bar screw 37 and is moved up and down in a horizontal state by the rotation of the bar screw 37. The vertical movement drive mechanism 28 is constituted by the vertical movement drive motor M2, the bar screw 37, and the vibration mechanism base plate 38.

  As shown in FIGS. 5, 8, and 9, the vibration mechanism unit 50 is provided on the vibration mechanism base plate 38. The vibration mechanism section 50 includes a vibrating body 52 in which the same number of test tubes 5 arranged in a horizontal row on the test tube rack 3, in this embodiment, five joint portions 51 are formed in a horizontal row, A vibration mechanism 53 that causes the vibration body 52 to vibrate is configured.

  Each joint 51 of the vibrating body 52 is a recess having a diameter that can receive the bottom of each horizontal row of test tube holders 16. The front and rear width of the vibrating body 52 itself is bonded to a certain horizontal row of test tube holders 16. The shape and size do not collide with the adjacent test tube holders 16 when vibration is applied. The vibrating body 52 may be made of resin or metal. However, when the vibrating body 52 is made of metal, it is desirable to treat the inner surface of each joint portion 51 with rubber or the like so as to prevent metal contact.

  The vibration mechanism 53 includes a vibration motor base plate 38 at positions of the vibration motor M3, the main pulley 54 coupled to the output shaft of the vibration motor M3, and the left and right ends of the bottom of the vibration body 52. Are coupled to each of the left and right driven pulleys 55 in an eccentric state and are rotated by the driven pulley 55 in an eccentric manner. Counterweight 57, a vibration plate 58 that pivotally supports the center axis of each of the left and right counterweights 57, and a vibrating body 52 on the vibration plate 58, and vibrates due to eccentric rotation of the left and right counterweights 57. The plate 58 performs a fine circular motion with a radius corresponding to the eccentric distance to vibrate the vibrating body 52 thereon.

  Next, operation | movement of the test stirring mechanism part 7 is demonstrated. This operation is controlled by the control system shown in FIG. That is, if there is an input such as a column designation input or a front row designation input to the control unit CTR, the control unit CTR controls the longitudinal movement drive motor M1 to determine the front / rear position of the vibrating body 52, and moves up and down. The driving motor M2 is driven to control the vertical movement of the vibrating body 52, and the vibration generating motor M3 is driven to control the vibrating body 52 to generate vibration.

  That is, as shown in FIG. 6, in the test tube stirring mechanism portion 7 located below the test tube rack 3, the vibrating body 52 is aligned with the row of the test tube holder 16 in the front row as the first position. In the front-rear direction alignment, the front-rear direction driving motor M1 is driven to move the stirring mechanism base 35 by an appropriate amount in the front-rear direction.

  After positioning in the front-rear direction, as shown in FIG. 7, the vertical movement drive motor M2 is activated to rotate the rod screw 37, and the inner screw tube 40 screwed to the rod screw 37 is driven up. Thereby, the vibration mechanism base plate 38 to which the inner screw tube 40 is fixed is raised horizontally. At this time, the guide shafts 36 inserted through the front left and right of the vibration mechanism base plate 38 guide the ascent of the vibration mechanism base plate 38.

  If the vibrating body 52 reaches the lower end of the frontmost test tube holder row by the ascent of the vibration mechanism base plate 38 and the bottom of each test tube holder 16 is inserted into each joint portion 51, the vertical drive motor M2 Stop. Subsequently, the operation proceeds to the vibration operation.

  8 and 9, the vibration generating motor M3 is driven to rotate the main pulley 54, and the main pulley 54 and the driven pulley 55 are rotated by the belt 56. As a result, the left and right counterweights 57 simultaneously perform the same eccentric rotation, and the vibration plate 58 pivotally supporting these counterweights 57 performs a fine circular motion with the radius corresponding to the eccentric distance. Then, the vibrating body 52 is vibrated. Due to the vibration of the vibrating body 52, horizontal vibration is applied in units of rows to the bottom portion which is the free end of the front row of horizontal test tube holders 16 inserted into the horizontal row of joint portions 51 of the vibrating body 52. . For this reason, horizontal vibration is similarly applied to the bottom of each test tube 5 mounted in each test tube holder 16, and the liquid inside is stirred.

  After the vibration operation for the test tube 5 in the horizontal row in the front row is continued for a predetermined time, the vibration generating motor M3 is stopped and the vibration operation is stopped. Then, the vertical drive motor M2 is reversely rotated to reversely rotate the rod screw 37, and the vibration mechanism base plate 38 is lowered by a certain amount until the bottom of the test tube holder 16 comes out of the joint portion 51 of the vibrating body 52. Thereafter, the vertical movement drive motor M2 is temporarily stopped, then the front-rear direction drive motor M1 is reversely rotated, the pinion gear 32 is also reversely rotated, and the rack 33 engaged therewith is moved backward, The stirring mechanism base 34 to which the rack 33 is fixed is moved backward. This moving distance is the row pitch of the test tube holder 16 in a row, and when the vibrating body 52 reaches the lower part of the test tube holder 16 in the second row from the front, the longitudinal driving motor M1 is stopped. Then, the backward movement of the stirring mechanism base 34 is stopped.

  After the alignment in the front-rear direction with respect to the second row, the vertical movement drive motor M2 is again activated in the upward rotation direction to rotate the rod screw 37 and raise the vibration mechanism base plate 38 horizontally. If the vibrating body 52 reaches the lower end of the second row of test tube holder rows by the ascent of the vibration mechanism base plate 38 and the bottom of each test tube holder 16 is inserted into each joint portion 51, it is used for vertical movement drive. The motor M2 is stopped. Subsequently, the operation proceeds to the vibration operation.

  The vibration operation is the same as that performed on the test tube holder 16 in the front row. By driving the vibration generating motor M3, the counterweight 57 is eccentrically rotated, and the vibrating body 52 is similarly horizontally oscillated. . As a result, horizontal vibration is applied to the bottom of the test tube holder 16 in the horizontal row of the second row, and the internal liquid is stirred by horizontally vibrating the bottom of each test tube 5 in each test tube holder 16.

  The vibration operation is continued for the predetermined time for the test tubes 5 in the horizontal row of the second row, and then the vibration generating motor M3 is stopped to stop the vibration operation. Thereafter, the control sequence similar to the back-and-forth movement, lifting and lowering operation, and the vibration operation for the second row is also used to move back and forth, the lifting and lowering operation, and the horizontal movement of each test tube holder row after the third row. Is repeated, and all of the many test tubes 5 arranged in the vertical and horizontal directions on the test tube rack 3 are stirred.

  As described above, according to the test tube agitation apparatus 1 of the present embodiment, each test tube is arranged in a horizontal row with respect to a large number of test tubes 5 arranged vertically and horizontally on the test tube rack 3. The bottom of the free end 5 can be vibrated to stir the liquid inside, and can be stirred efficiently and effectively. And the test tube 5 can be protected by the test tube holder 16 made of an elastic material, and high-speed vibration can be applied without being damaged.

  In addition, according to the present embodiment, the test tube can be agitated in units of one row at a time in order from the test tube row of the first row, such as the first row, the second row, the third row, etc. For example, by inputting a command of stirring in the second row or stirring in the fourth row to the control unit CTR, the motors M1, M2, M3 can be driven to perform the stirring operation in units of rows. The tube can be stirred.

  Furthermore, as shown in FIG. 18, after the nozzles of the dispensing head 6 that are also aligned vertically and horizontally are positioned up and down with respect to the chips 2 that are aligned vertically and horizontally, the tips 2 are mounted at once by being lowered. If the test tube stirring device 1 of this embodiment is incorporated into the dispensing device 100 that dispenses reagents and the like through the chip 2, a series of operations from dispensing work to chemical solution stirring is continuously performed. And can be done efficiently. As a result, it is particularly effective in an examination center where a large number of specimens gather.
