The present invention relates to an improvement of a chip alignment apparatus for setting in advance.

  A chip (chip nozzle) that is used by being attached to a testing device for analyzing and processing samples such as blood and serum so as to act as a nozzle when aspirating and dispensing the sample is usually used once to prevent contamination. After the suction / dispensing operation is performed, it is removed and replaced with a new tip, and the removed tip is discarded and used.

  For this reason, in order to prepare a large number of new tips to be used for each suction / dispensing operation in the inspection device, the tip rack in which a large number of tips are set and held is mounted and removed. It is equipped freely and the chip is supplied to the inspection apparatus through this chip rack.

  The setting operation for inserting and setting the chips into the hole for holding the chip, which has been established vertically and horizontally in the chip rack, is usually performed manually by hand.

  However, the device that automatically sets the chips to the chip rack is also provided at the end of the chip transport rail by taking out the chips put into the chip tank one by one with the chip supply device and supplying them to the chip transport rail. 2. Description of the Related Art Conventionally, it is known as a chip aligning device for dropping and setting a chip rack from a chip dropping section.

  As shown in FIG. 1, this conventional apparatus forms a rectangular platform-like machine base a that is long in the front and rear direction and short in the left and right directions. A box-shaped chip tank c that accommodates the chip b is mounted on a portion that is biased to the side, and the floor of the box is mounted on an inclined wall that slopes downward from the front to the rear, and the rear end in the chip tank c As shown in FIG. 2, the flat belt 11 is wound endlessly on the upper and lower rollers 10, 10 with the axial direction being the left-right direction, and one chip is placed on the outer peripheral surface of the flat belt 11. a chip supply belt unit in which fins d having a width corresponding to the width of the chip b are mounted in parallel in the longitudinal direction of the flat belt 11 at a predetermined interval so as to be able to support b. e, its lower end side is connected to the inclined descending end of the floor plate of the chip tank c The upper end side of the chip tank c is arranged so as to protrude upward from the opening on the upper surface side of the chip tank c, and this is mounted, as shown by the arrow in FIG. The front side is made to rise and rotate. As a result, a large number of chips b placed in the chip tank c are picked up and fed one by one by the fin d that moves upward, It is made to discharge | release to back by the turning part of the flat belt 11. FIG.

  Then, a guide chute f that is inclined and lowered so as to receive the tip b discharged from the upper end of the unit e at the rear portion of the tip supply belt unit e and flow downward toward the left and right sides of the machine base a. A chip transport rail g for mounting and mounting on the machine base a, receiving the chip b flowing down at the inclined lower end of the guide chute f, and transporting the chip b toward the front side of the machine base a. Is mounted on the machine base a.

  As shown in FIGS. 3 and 4, the chip transport rail g is composed of a horizontally long side plate-like rail 12 having a vertical width corresponding to the vertical length of the chip b, and an enlarged diameter on the upper end side of the chip b. A pair of left and right sides are opposed to each other with a space slightly narrower than the diameter of the outer periphery of the part b ′, and are supported on the machine frame 13. The machine frame 13 is installed and fixed on the upper surface of the machine table a as shown in FIG. It is configured by being supported on the upper surface side of the provided vibration generator 14 that generates vibration from the magnet Mg via two leaf springs 15 inclined in the conveying direction (leftward in FIG. 4). However, the distance between the pair of opposing side plate-like rails 12 and 12 is slightly narrower than the diameter of the enlarged diameter portion on the base end side of the tip b. The tip b placed on the transport rail g has a tip having a smaller diameter than the interval. Falls within the interval between the rails 12 and 12, and the proximal end side having a diameter larger than the interval is caught without falling into the interval, so that the neck portion of the enlarged diameter portion b ′ on the proximal end side becomes a pair. It is hooked on the upper surface of the rails 12 and 12 and converted into a posture in which the tip end side of the small diameter hangs within the interval, and is supported by the rails 12 and 12 in the converted posture, and as shown in FIG. Are transported in parallel.

  As shown in FIG. 5, at the terminal end of the chip transport rail g in the transport direction, the tip b that is sent is received by the arc-shaped cutout portion 16 at the peripheral edge and sent to the chip dropping portion h. As shown in FIGS. 6 and 7, the pair of sandwiching arms 18 and 18 are opened and closed around the fulcrum shaft 19 so as to fall into the tip dropping portion h. A chip detection sensor j is provided for detecting the presence or absence of the held chip b when the chip holding chuck i for holding the coming chip b is assembled and the holding arms 18 and 18 are closed to hold the chip b. When the chip b falls on the chip dropping portion h, the chip holding chuck i is held in a closed state. When the chip b is detected by the chip detection sensor j, the chip holding chuck i is opened. Then, the chip b is dropped and set in the rack R to be disposed below, and when the chip detection sensor j determines that there is no chip b, the chip holding chuck i is closed and the rotating plate 17 moves by one frame, The operation is repeated.

  Thus, a large number of chips b put into the chip tank c are picked up one by one by the fins d of the chip supply belt unit e and supplied to the chip transport rail g. It was controlled to move in two directions, vertical and horizontal, on the machine table a below the chip dropping part h by being transported to the end in the transporting direction and falling after reaching the chip dropping part h provided at the end. This is a chip aligning device that is sequentially set in each chip holding hole of a chip rack R that is mounted on the abutment.

  In this conventional chip aligning apparatus, when the chip b in the chip tank c is scooped up by the chip supply unit e and supplied to the chip transport rail g, the bottom side of the rotating flat belt 11 is thick in FIG. As indicated by the arrows, the chip b can be formed by constantly stirring a large number of chips b in the chip tank c and thereby changing the posture of the chip b in the chip tank c in a complicated manner. As shown in FIG. 8, there are two or three bamboo shoots that are connected and connected to each other. Since the number increases in proportion to the time, it is necessary to periodically stop the operation of the apparatus and disassemble the chips b fitted manually, which deteriorates the work efficiency.

  Further, since the tip b is tapered toward the tip, the tip b is in a posture in which the tip end side of the tip is lowered by stirring by the tip supply belt unit e, as shown in FIG. When the tip supply belt unit e flows to the circulating portion at the bottom, the thin tip side comes to bite between the rotating fin d and the floor surface of the tip tank c, or The chip b is chipped, bent, or cracked at the tip of the metal plate on the wall of the chip tank c, so that the chip b set in the chip rack R supplied to the chip transport rail g is defective. As a matter of fact, there is a problem that causes an error in the inspection result.

  A problem to be solved by the present invention is that in a chip aligning apparatus that automatically sets chips in a chip rack, the chips placed in the chip tank are not damaged and are fitted in a bamboo shoot shape. Therefore, a supply means capable of reliably and speedily supplying the chip transport rail is provided.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 10 is a partially broken perspective view of the chip aligning apparatus W that implements the chip supply means according to the present invention. In the same figure, a is a machine base formed in the shape of a long board in the front-rear direction, 2 is a chip tank mounted on the machine base a, g is a chip transport rail for transporting chips b taken out from the chip tank 2, h denotes a chip dropping portion provided at the end portion of the chip transport rail g, and R denotes a chip rack that is arranged below the chip dropping portion h and can be placed on the upper surface of the machine base a.

  As shown in FIG. 13, the chip tank 2 has a rectangular box shape in which the horizontal width substantially corresponds to the length dimension of the chip b and the vertical width is longer than the horizontal width in plan view. The longitudinal direction in the plan view (vertical direction in FIG. 13) is in the front-rear direction (diagonal left-right direction in FIG. 10) with respect to the machine base a formed in a long base shape in the front-rear direction. As a state and posture substantially orthogonal to each other, it is mounted via a support machine frame at a predetermined height position at a portion biased to the left and right sides on the rear end side of the machine base a.

  The chip tank 2 formed in a long rectangular box shape in the plan view has a floor plate 20 in one direction along the longitudinal direction in the plan view (in a diagonally forward direction in FIG. 10 and indicated by an arrow in FIG. 11). It is formed into an inclined plate that is gently inclined downward (to the left direction), and is thus placed in the chip tank 2 so that the axial direction is perpendicular to the longitudinal direction of the floor plate 20 described above. As shown in FIGS. 11 and 12, the chip b is made to flow and move toward the left end of the floor plate 20 on the inclined downward side.

  The inclination of the floor plate 20 of the chip tank 2 is for allowing the chip b introduced into the chip tank 2 to flow toward the inclined downward side, and in the illustrated example, it is formed in a box shape. The floor 20 is inclined by mounting the chip tank 2 in an inclined posture, but the chip tank 2 may be mounted horizontally and only the floor 20 may be inclined.

  In addition, as shown by a chain line in FIG. 11, a conveyor device K in which the belt rotates endlessly is provided on the floor surface of the chip tank 2. You may make it move sequentially.

  An opening 21 having a narrow width and extending over almost the entire area in the width direction of the floor board 20 is formed at the end of the floor board 20 on the descending slope side. The opening 21 has a narrow width in the inclination direction of the floor plate 20 substantially corresponding to the outer diameter of the chip b, and a length in the width direction of the floor plate 20 substantially corresponding to the length of the chip b. It is.

  Then, an end face 30 at the top is formed in the opening 21 in a shape and area corresponding to the opening face of the opening 21, and one chip b is placed on the end face 30 in a lying posture. Sometimes, the chip supply bar 3 that can support the chip b in its posture is arranged so as to go up and down through the opening 21.

  In this embodiment, the chip supply bar 3 has a cross-sectional shape substantially corresponding to the opening surface of the opening 21 described above, and is formed in a square plate shape that is continuous to a height corresponding to the range in which the lifting and lowering operation is performed. As shown in FIGS. 11 and 12, on the lower end side thereof, an operating rod 31 is arranged below the chip tank 2 and linked to the lifting operation mechanism 4 assembled and supported on the support machine frame 1 described above. Are connected.

  The lifting / lowering operation mechanism 4 includes a motor M, a crank arm 41 that rotates while being connected to an output shaft of the motor M via a speed reduction mechanism 40, and the operating rod 31 that has a lower end connected to the rotation end of the arm 41. And a guide cylinder 43 which is inserted into the outer periphery of the operating rod 31 and supported on the frame 42 so as to regulate the operating direction of the operating rod 31, and the crank arm 41 is rotated by the operation of the motor M, thereby It is a normal one that reciprocates the working rod 31 up and down along the direction regulated by the cylinder 43.

  The tip supply bar 3 reciprocates up and down by the operation of the operating rod 31 that moves up and down by the operation of the elevating operation mechanism 4, and when the upper and lower operations are in the descending operation, the top end surface 30 is opened 21. In the ascending operation, the position where the top end face 30 penetrates the deposited layer of the chip b put in the chip tank 2 and is exposed upward is raised. It is set to be the end of operation. Thereby, when the lowering operation reaches the end and the end surface 30 at the top occupies a position aligned with the opening surface of the opening 21, the chip tank 2 flows toward the opening 21 along the upper surface of the floor plate 20, As shown in FIG. 11, the chip b that has been dammed to the chip supply bar 3 is placed on the end surface 30 at the top of the chip supply bar 3 and is supported by the end surface 30. When the supply bar 3 moves up and moves up, the chip b placed on the end face 30 is pushed up as shown in FIG.

  In order to prevent the chip b mounted on and supported by the end surface 30 from falling into the chip tank 2 when the chip b is pushed up by the end surface 30 at the top of the chip supply bar 3. The end face 30 is formed on an inclined surface that is inclined downward to the opposite side of the chip tank 2 so that the chip b to be placed can move to the opposite side of the chip tank 2 by flow or rolling due to its own weight. Further, at the front position of the chip supply bar 3 located on the side opposite to the chip tank 2 of the chip supply bar 3, the chip moves on the inclined lower side on the inclined end surface 30. A guide wall 5 for blocking the movement of b and positioning the chip b on the end face 30 is installed along the locus of the chip supply bar 3 ascending / descending operation.

  Thus, the chip b placed on the end surface 30 at the top of the chip supply bar 3 is held on the end surface 30 by the inclined surface of the end surface 30 and the guide wall 5 provided along the operation locus of the chip supply bar 3. It will be pushed up. At this time, the chip b that has laid over the chip b directly mounted on the end surface 30 is formed in a cylindrical shape and the peripheral surface is formed in a curved surface having an arc shape. Since the chip is placed in an unstable state on the chip b directly placed on the chip b, the chip supply bar 3 is spilled on the chip tank 2 side during the raising operation of the chip supply bar 3, and only one chip b placed directly on the end face 30 is present. The tip supply bar 3 is pushed up to the end position of the lifting operation.

  The above-mentioned guide wall 5 is set so that the height position of the upper edge of the guide wall 5 occupies a height position substantially aligned with the position of the top end face 30 at the end of the ascent operation of the chip supply bar 3. The tip b pushed up by the tip supply bar 3 is discharged to the inclined downward side of the end surface 30 by the inclined surface of the end surface 30 when the contact with the guide wall 5 is lost.

  From this, the upper part of the upper edge of the guide wall 5 is used as a discharge port for the chips b pushed up one by one from the chip tank 2 by the chip supply bar 3, and the discharged chips b are transported here. By providing a chute for guiding to the rail g or by providing a chip transport rail so as to directly receive the released chip b, the chips b in the chip tank 2 are taken out one by one to transport the chips. A chip supply device for supplying the rail is configured.

  In this embodiment, the chip transport rail g is placed in the transport direction in the outer position of the upper end edge of the guide wall 5 serving as the discharge port of the chip b (the outer position on the inclined lower side of the end face 30). The continuous direction of the rails 12 and 12 is arranged so as to be orthogonal to the inclination direction of the floor surface 20 of the chip tank 2, and thereby, the tip supply bar 3 can be laid down from the top end face 30. As shown by a chain line in FIG. 13, the chip b released in the posture is received by the two rails 12 and 12 that are parallel to each other while being in the sideways posture.

  Since the tip b is formed in a shape having an enlarged diameter portion b ′ on the base end side as shown in FIG. 15, only this enlarged diameter portion b ′ is placed on the rails 12 and 12 and has a small diameter. When the tip end side of the arm 12 falls into the interval between the rails 12 and 12, the neck portion of the enlarged-diameter portion b ′ rotates around the fulcrum, and as shown in FIG. It is supported by the rails 12 and 12 and is conveyed in this state.

  The chip transport rail g has the same configuration as the chip transport rail g described as the chip supply means of the conventional chip alignment apparatus W in FIGS. 3 and 4, and is a vibrator type that transports in one direction by vibration. Of the configuration.

  FIG. 13 shows only the start end side in the transfer direction of the chip transfer rail g having the configuration shown in FIGS. 3 and 4 and omits the end side. Therefore, as shown in FIG. 13, the tip b released on the pair of parallel rails 12, 12 in a lying position is leftward as shown by the alternate long and short dash line in FIG. 13. In the posture in which the enlarged-diameter portion b ′ is positioned at the right and the tip end side tapering to the right is released, when released, it is swung in a vertical posture around the enlarged-diameter portion b ′, thereby It is held at the position and is transported from this position toward the end side as indicated by the double-lined arrow. Further, as shown by the dotted line in FIG. 13, the released tip b has a posture in which the enlarged diameter portion b ′ is positioned on the right side and the tapered tip side is positioned on the left side. When held, it is held at the position indicated by the dotted line B in FIG. 13 and transferred from this position toward the end side.

  From this, the tip b of the rails 12 and 12 in which the tip b held and transferred by the rails 12 and 12 is transferred to the front side in the inclined direction of the end surface 30 at the top of the tip supply bar 3 is provided. The next chip b is moved by the chip supply bar 3 that moves up in a predetermined cycle set in the lifting / lowering operation mechanism 4 while still in the range A facing the supply bar 3. There is a case where it is pushed up and discharged onto the rails 12 and 12.

  At this time, as shown in FIG. 16, when the tip b pushed up rolls the inclined surface of the end surface 30 to the inclined downward side, the peripheral surface thereof is held by the rails 12 and 12. The tip b is held on the end surface 30 of the tip supply bar 3 by being prevented from being released by hitting the enlarged diameter portion b ′ of the tip b, and the end surface is lowered by the lowering operation of the tip supply bar 3. It moves down while being supported by 30 and rises again to the discharge position by the raising operation, and this operation is repeated while the tip b exists in the range A on the rails 12 and 12. And when it rises to the discharge position, it will be discharged to the rails 12 and 12 when the tip b does not exist in the aforementioned range A.

  Accordingly, the chips b are not supplied in duplicate on the chip transport rail g, but are supplied one by one, and are transferred in a row on the rails 12 and 12 to the end side. . Then, at the end part of the chip transport rail g, the chip dropping part h provided as described with reference to FIGS. 5, 6 and 7 is taken out one by one and arranged below the chip dropping part h. It is set in the chip hole of the rack R.

  17 and 18 show another embodiment. In this example, the tip end surface 30 of the tip supply bar 3 that moves up and down is an inclined surface that slopes downward toward the opposite side of the chip tank 2, but the chip supply bar 3 moves up and down along the vertical direction. Thus, the lifting operation mechanism 4 is configured, and the top end surface 30 is an inclined surface that obliquely crosses the perpendicular direction.

  In the first embodiment, the tip supply bar 3 is formed in a rectangular shape in which the end face 30 at the top and the end face at the bottom are parallel to each other in a side view, whereas the end face at the bottom is aligned with a horizontal surface. The top end surface 30 is formed into a trapezoidal shape with an inclined surface.

  Further, the guide wall 5 provided on the front side in the inclination direction of the top end surface 30 at the adjacent position along the locus of the chip supply bar 3 ascending / descending operation is arranged along the vertical direction of the chip supply bar 3. Since this is performed, the chip supply bar 3 is vertically installed along the vertical operation locus of the chip supply bar 3.

  As a result, the chip b that has moved on the floor plate 20 of the chip tank 2, transferred to the end surface 30 at the top of the chip supply bar 3, and moved to the inclined downward side due to the inclination of the end surface 30 is transferred to the vertical guide wall 5. When the tip supply bar 3 rises in this state, the end surface 30 abuts against the wall surface of the guide wall 5 by the movement of the end surface 30 being stopped. It is pushed up while being held in a supported state, reaches the upper edge of the guide wall 5, and disengages from the guide wall 5, so that it rolls to the inclined downward side of the end face 30 and is released. It is made to do.
