  As shown in FIG. 1, FIG. 2 and FIG. 4, the vibration exciter 4 is installed on an installation base 3 having four legs 2, and a base 4a, an electromagnet 4b, a vibration base 4c and two leaf springs 4d. The first transport unit 10 and the second transport unit 20 are vibrated at a frequency of 25 to 50 Hz in a direction parallel to the transport direction of the nozzle chip C (the left-right direction in FIGS. 2 and 3).

  The pedestal 4a is fixed on the installation table 3, the electromagnet 4b is placed on the upper surface, and front and rear end surfaces are formed obliquely. The vibration table 4c is provided with a movable iron core of the electromagnet 4b, and front and rear end surfaces are formed obliquely. The leaf spring 4d has a lower part attached to the end face of the base 4a and an upper part attached to the end face of the vibration table 4c. Thereby, the vibration table 4c is vibrated by the electromagnet 4b, and vibrates the connecting member 5 in the left-right direction in FIGS.

  Here, as shown in FIGS. 1, 2, and 4, the connecting member 5 is provided with a support plate 6 to which a support 7 and two supports 8 are attached in the front and rear. The support column 7 supports the first transport unit 10, and the two support columns 8 are provided with a second transport unit 20 on a pedestal 8 a formed at the top. On the other hand, the pedestal 8a is formed with a guide slope 8b for guiding the transfer of the nozzle chip C by dropping onto the lower transport rail 23 on the downstream side in the transport direction of the nozzle chip C. A guide member 9 is installed between the support column 7 and the one support column 8.

  The guide member 9 is a member that guides the discharge of the nozzle chip C having a poor posture that is stacked in a nested manner. The guide pieces 9 are attached to both the support column 7 and one support column 8 on both sides of the substantially box-shaped main body 9a. have. The main body 9a has wall surfaces on the front side and front and rear along the conveying direction of the nozzle chip C, and the back side is open. In the main body 9a, a guide plate 9d projecting obliquely upward and outward is formed at an upper portion on the front side, and a discharge guide plate 9e projecting obliquely downward and outward is formed at a lower portion on the back side. The discharge guide plate 9e guides the nozzle chip C discharged from between the pair of transport arms 12d and the pair of upper transport rails 21 while rotating around the central axis, and to the recovery unit Pr (see FIG. 13). And let it fall.

  The 1st conveyance part 10 has the conveyance member 12 and the supply guides 14 and 15 as shown in FIGS.

  As shown in FIGS. 3 and 6 to 8, the conveying member 12 is a longitudinal member having an end block 13 provided at one end, and is horizontally supported by a support block 11 attached to the column 7. . The conveying member 12 is formed with a conveying groove 12b over the entire length of the upper surface of the main body 12a formed of metal or synthetic resin, and a slit 12c provided along the conveying direction of the conveying groove 12b on the right half side of the main body 12a. Thus, a pair of transfer arms 12d is formed. The conveyance groove 12b is a groove that conveys a plurality of nozzle chips C to be supplied while being aligned in a row in a lying state by vibration. As shown in FIG. 9, the width of the bottom surface is a large-diameter portion at one end of the nozzle chip C. An inclined surface that is slightly wider than the diameter of the bottom surface and that increases toward the outside is formed on both sides of the bottom surface.

  At this time, the bottom surface of the conveyance groove 12b is arranged on the same straight line as the slit 12c when viewed in the conveyance direction of the nozzle chip C, as shown in FIGS. Further, as shown in FIG. 9, the inclined surface of the conveying groove 12b is formed such that the front side is higher than the back side. The pair of transport arms 12d support the stepped portion D, which is a lower support portion of the nozzle tip C, and transport the nozzle tip C by vibration applied by the vibration generating unit 4. Here, if each transfer arm 12d has a chamfer with a curved surface over its entire length at the inner upper part that contacts the step portion D, the nozzle tip C is smoothly transferred without being caught by the step portion D during transfer. can do.

  The supply guides 14 and 15 guide the dropping of the plurality of nozzle chips C supplied to the conveying member 12 so as to cover the periphery of the conveying member 12 into the conveying groove 12b, and also regulate the dropping from the conveying groove 12b. The supply guide 14 covers the front surface and the left side surface of the conveying member 12, and as shown in FIGS. 1 to 4, the side plate 14a screwed to the front surface of the conveying member 12 and the inclination inclined obliquely toward the conveying groove 12b. An end face plate 14c attached to the end face of the plate 14b and the end block 13 and extending upward from the end block 13 is integrally formed by bending. The supply guide 15 covers the back surface of the conveying member 12, and a side plate 15a screwed to the back surface of the conveying member 12 and an inclined plate 15b inclined obliquely toward the conveying groove 12b are integrally formed by bending.

  Here, the nozzle tip C is a disposable nozzle used in the dispensing device of the automatic analyzer, and as shown in FIG. 5, both ends are open and the cross-sectional area at one end is larger than the cross-sectional area at the other end. In addition, a flange F is formed on the outer periphery of one end, and a step portion D serving as a lower support portion is formed on the outer periphery of the one end side. In the nozzle tip C, the lower portion of the flange F serves as an upper support portion, and the center of gravity G1 exists between the center point Ct and the step portion D. For this reason, the nozzle chip C supplied to the conveying groove 12b falls on the bottom surface of the conveying groove 12b and is returned by the inclined surfaces on both sides even if it rolls left and right as shown by the arrows in FIG. 9 due to vibration. At the same time, the side plates 14a and 15a are controlled to fall and are transported in a lying state in the transport groove 12b.

  As shown in FIGS. 1 to 4 and FIGS. 6 to 8, the second transport unit 20 includes a pair of upper transport rails 21 and lower transport rails 23 each molded from metal or synthetic resin. Yes.

  As shown in FIGS. 6 and 7, the upper transport rail 21 is disposed on the upper surface of the base 8 a of the support column 8 with one end disposed above the end of the transport arm 12 d, and transports the nozzle chip C of the first transport unit 10. Adjacent to each other along the direction. The upper transport rail 21 is formed with a support flange 21b that abuts the lower portion of the flange F on the lower side surface of the main body 21a to support the nozzle chip C, and the support flange 21b extends to the first transport unit 10 side. It has a piece 21c. The pair of upper transport rails 21 are held in parallel to each other so that the space between the support flanges 21b and 21b is slightly larger than the diameter of the lower portion of the flange F of the nozzle tip C by spacers 22 provided at two positions on the upper portion of the main body 21a. As shown in FIG. 10, the nozzle tip C is supported at the lower part of the flange F by the support flanges 21b and 21b and conveyed. Here, the distance between the bottom surface of the conveying groove 12b and the upper surface of the support flange 21b is set slightly shorter than the distance between the lower surface of the flange F of the nozzle tip C and the step portion D.

  Further, as shown in FIG. 10, the support flange 21b is chamfered with a curved surface on the upper support portion of the nozzle tip C, that is, the upper inner side supporting the lower portion of the flange F, as shown in FIG. For this reason, the upper conveyance rail 21 can convey the nozzle chip C smoothly, without the lower part of the flange F used as an upper support part catching at the time of conveyance. In particular, when this chamfer is applied to the upper inner side of the pair of transfer arms 12d formed by the slits 12c, the nozzle tip C supplied to the transfer member 12 in various postures is supplied in a lying state, for example, There is an advantage that the nozzle tip C can be smoothly transported without the upper portion of the flange F being caught inside the upper portion of the transport arm 12d.

  As shown in FIGS. 6 and 7, the lower transport rail 23 is installed on the lower surface of the base 8 a of the support column 8 along the transport direction of the nozzle chip C. The lower conveyance rail 23 is formed with a support flange 23b that abuts the lower portion of the flange F and supports the nozzle chip C on the lower side surface of the main body 23a. The pair of lower transport rails 23 are held in parallel with each other so that the space between the support flanges 23b and 23b is slightly wider than the diameter of the lower portion of the flange F of the nozzle tip C by spacers 24 provided at two positions on the upper portion of the main body 23a. The The pair of lower transport rails 23 is transported by the pair of upper transport rails 21, and supports the nozzle chip C carried in through the guide inclined surface 8b of the base 8a by supporting flanges 23b and 23b below the flange F. To do.

  The transport device 1 configured as described above vibrates the first transport unit 10 and the second transport unit 20 by the vibration generating unit 4 when transporting a plurality of nozzle chips C to a dispensing device of an automatic analyzer, for example. The plurality of nozzle chips C are supplied from the supply guides 14 and 15 to the conveying member 12. Then, the plurality of nozzle chips C are guided by the supply guides 14 and 15 and dropped onto the transport groove 12b, and after the first transport unit 10 is transported in one row by vibration, the pair of transport chips 12d It is sequentially transferred to a set of upper transport rails 21. Then, each nozzle chip C transferred to the upper transport rail 21 is transported on the upper transport rail 21 by vibration, and then guided to the guide slope 8b of the base 8a and carried into the set of lower transport rails 23. It is transported to the end by the lower transport rail 23.

  At this time, in the first transport unit 10, a pair of transport arms 12d is formed on the transport member 12 by the slits 12c. Further, the nozzle tip C has a center of gravity G1 between the center point Ct in the longitudinal direction and the step portion D. For this reason, when the nozzle chip C is dropped onto the conveying groove 12b, all of the nozzle chips C fall down. And the several nozzle chip C conveyed by the 1st conveyance part 10 by vibration is conveyed in the row on the conveyance groove | channel 12b in a lying state.

  After that, the nozzle chip C transported in the lying down state stands up due to the difference in the position of the center of gravity G1 and the stepped portion D which is the lower support portion when moving from the transport groove 12b to the pair of transport arms 12d. In the state, it is transported along a pair of transport arms 12d. For this reason, the conveying device 1 utilizes the difference in the position of the center of gravity G1 of the nozzle tip C, and the posture of the nozzle tip C is determined by the simple structure of the conveying member 12 in which a pair of conveying arms 12d are formed by the slits 12c. Can be controlled from the lying state to the standing state.

  Further, the nozzle tip C is formed in a long conical cylinder shape having both ends opened and having a cross-sectional area at one end larger than that at the other end. For this reason, when a plurality of nozzle chips C are supplied from the supply guides 14 and 15 to the transport member 12, a plurality of nozzle chips C overlap, for example, as shown in FIG. When viewed from the longitudinal direction, the overlapping nozzle chip C shifts to the flange F side of one end having a larger cross-sectional area and becomes the center of gravity G2.

  For this reason, the nozzle chip C overlapped in a nested manner becomes a top heavy with the center of gravity positioned above. Accordingly, as shown in FIGS. 12 and 13, such a nozzle chip C is conveyed on the conveying groove 12b in a lying state, and the position of the center of gravity G2 remains at one end even when the nozzle chip C moves to the pair of conveying arms 12d. Since it exists on the flange F side, the lying state is maintained, and it does not stand up like a single nozzle tip C. For this reason, since the nozzle chip C with a poor posture superimposed in a nested manner is conveyed on the set of transfer arms 12d in a lying state, the set of transfer arms 12d from the set of transfer arms 12d is set like a single nozzle chip C. The upper transfer rail 21 is not transferred.

  Then, as shown in FIGS. 12 and 14, the nozzle chip C with a poor posture superimposed in a nested manner is transported on a pair of transport arms 12 d, and then the first transport unit 10 and the second transport unit 20. Are ejected from between the pair of transport arms 12 d and the pair of upper transport rails 21 that are the boundaries of, and fall to the guide member 9. As shown in FIGS. 12 and 13, the poorly positioned nozzle chip C that has fallen into the guide member 9 and is nested is guided by a discharge guide plate 9 e that protrudes obliquely downward toward the back side, and is thus rotated around the central axis. It will fall to the collection part Pr while rotating at the same time. In this way, the nozzle chips C with poor posture that are collected in the collecting portion Pr in a nested manner are drawn to the individual nozzle chips C and then supplied again from the supply guides 14 and 15 for use.

  As described above, the transport device 1 can easily control the posture of the nozzle chip C by the transport member 12 having a simple structure, and the first transport unit 10 and the second transport unit 20 including the transport member 12. By using this, it is possible to easily discharge the nozzle chip C having a poor posture that is nested. In addition, since the transport device 1 uses a simple mechanical configuration of the first transport unit 10 and the second transport unit 20 that transports the nozzle chips C, the transport device 1 has an advantage that the number of components is small and the size is small. is doing.

  Moreover, since the conveying apparatus 1 comprises the conveying member 12 of the first conveying unit 10 and the upper conveying rail 21 and the lower conveying rail 23 of the second conveying unit 20 from block-shaped rails, these are constituted by metal plates. The generated vibration noise can be suppressed to a lower level than that of the conventional transfer device. Further, since the transport device 1 defines the distance between the upper transport rail 21 and the lower transport rail 23 of the second transport unit 20 by the spacers 22 and 24 arranged at the upper part, the distance between the rails can be determined by determining the length of the spacer. Are uniformly determined, and adjustment work is unnecessary, and the spacer is arranged on the upper part of the rail, so that the assembling work is facilitated.

  Here, the conveyance groove 12b is not limited to the above-described shape composed of three planes as long as the nozzle chip C is conveyed to the position of the slit 12c forming the pair of conveyance arms 12d. For example, as shown in FIG. 15, it may be formed by a curved surface.

  Moreover, although the exciting part 4 used the electromagnet as a drive means, if the goods can be conveyed by vibrating the 1st conveyance part 10 and the 2nd conveyance part 20, it will not be limited to an electromagnet.

  Further, the article conveyed by the conveying device 1 is not limited to the disposable nozzle tip C used in the dispensing device of the automatic analyzer, and at least one end is open and the cross-sectional area of one end is the other end. 16 may be a reagent container or a beverage cup, for example, a beverage cup 30 shown in FIG. 16.

  As shown in FIG. 16, the cup 30 has an opening 30a at the upper end of one end, a bottom surface 30b is formed at the other end, and the side wall 30c is inclined so as to expand in the radial direction from below to above. Yes. As shown in FIGS. 16 and 17, the cup 30 has a center of gravity G3 substantially in the middle in the vertical direction, and a point PL in the middle of the inclined side wall 30c between the opening 30a and the center of gravity G3 serves as a lower support portion. It is supported by a pair of transport arms 12d of the transport unit 10. Further, as shown in FIG. 18, the cup 30 has a point PU between the opening 30a of the side wall 30c and the point PL as an upper support portion, and a pair of the upper transport rail 21 and the lower transport rail 23 of the second transport portion 20. Supported by.

  For this reason, when two cups 30 are nested, as shown in FIG. 19, the position of the center of gravity shifts to the opening 30a side of one end having a larger cross-sectional area and becomes the center of gravity G4. For this reason, the two cups 30 nested in a nested manner will fall down because the position of the center of gravity G4 is located above the side wall 30c with which the transport arm 12d contacts, even if it is supported by the pair of transport arms 12d. It is discharged from between the pair of transport arms 12d and the pair of upper transport rails 21 at the boundary between the first transport unit 10 and the second transport unit 20.

  The second transport unit 20 according to the embodiment includes an upper transport rail 21 and a lower transport rail 23. However, the second transfer unit 20 transfers the set of transfer arms 12d from the set of transfer arms 12d to a set of parallel upper transfer rails 21 to a desired position, or sets a set of nozzle chips C nested in one end. The lower transfer rail 23 may not be provided as long as it can be discharged from between the transfer arm 12d and the pair of upper transfer rails 21.

  In addition, the conveying member 12 that constitutes the first conveying unit 10 includes a conveying groove 12b that conveys a plurality of articles supplied to the main body 12a in a line in a lying state by vibration, and a conveying groove 12b in the conveying direction of the conveying groove 12b. It is only necessary to have a pair of transfer arms 12d that are formed by slits 12c provided along and support and convey a lower support portion between one end of the article and the center of gravity. Therefore, the conveying member 12 is different from the embodiment in which the slit 12c is formed from the middle of the conveying groove 12b, the slit 12c is formed over the entire length of the conveying groove 12b, and the nozzle chip C is formed by a pair of conveying arms 12d. The lower support portion (step D) and the lower support portion (point PL) of the cup 30 may be supported and conveyed.
