Description

  The present invention relates to a syringe take-out device that can smoothly take out a large number of syringes housed in a resin sheet bag-like container.

  Before filling a syringe as a main body of a syringe with a chemical solution, it is necessary to take out an empty syringe transported in a state of being stored in a large number of containers for transfer and transfer it to a conveyor or the like, for example.

  When this transfer operation is performed manually, it is inefficient and cumbersome, and thus an apparatus for taking out the box regardless of the manual operation has been proposed.

  For example, Patent Document 1 discloses a supply means that can take out a large number of syringes from a container at a time and supply them to a supply position.

  However, this supply means inserts and holds empty syringes in advance in a large number of through-holes formed in a plate-shaped holder, and in advance, inserts them into the through-holes of the holder before storing them in a transport box. The pre-processing of inserting is necessary, and this pre-processing is an operation of taking out empty syringes stacked in the box by some means and inserting them one by one into the through hole of the plate-shaped holder. .

  Further, it is conceivable that the syringe is adsorbed and taken out by a negative pressure, but there is a possibility that the container itself is adsorbed. That is, in order to prevent dust and dust from adhering to the syringe, the container is often a bag made of a resin sheet such as vinyl. It will be adsorbed and it will be difficult to remove the syringe smoothly.

  As shown in FIG. 1, the syringe take-out device 10 according to the embodiment of the present invention includes a supply tray 20 and a suction head device 54.

  The supply tray 20 has a rectangular parallelepiped box shape having a bottom wall 27 and opened upward, and a pair of two parallel outer peripheries out of four outer peripheral walls surrounding the inner space 28. The walls 23 and 24 are composed of a pair of orthogonal outer peripheral walls 25 and 26 orthogonal to the walls 23 and 24.

  Further, as shown in FIG. 2, the size of the inner space 28 surrounded by the outer peripheral wall is such that the axis 12A of the syringe 12 is orthogonal to the parallel outer peripheral walls 23 and 24 (parallel to the orthogonal outer peripheral walls 25 and 26). A container 60 that is stacked in a posture and accommodated in a rectangular parallelepiped shape can be received from above.

  The parallel outer peripheral wall 23 is composed of a parallel outer wall 23A and a parallel inner wall 23B, the parallel outer peripheral wall 24 is composed of a parallel outer wall 24A and a parallel inner wall 24B, and the orthogonal outer peripheral wall 25 is an orthogonal outer wall 25A. The orthogonal outer peripheral wall 26 includes an orthogonal outer wall 26A and an orthogonal inner wall 26B. The parallel outer walls 23A, 24A and the orthogonal outer walls 25A, 26A continuously constitute a four-sided outer peripheral wall, and the parallel inner walls 23B, 24B and the 25 orthogonal inner walls 25B, 26B are separate from each other. Are disposed inside the continuous parallel outer walls 23A, 24A and the orthogonal outer walls 25A, 26A.

  A suction port 30 is formed at the center of the parallel outer wall 23A. In addition, lattice-shaped communication grooves 23C and 24C communicating with the suction port 30 are formed on the outer surfaces of the parallel inner side walls 23B and 24B, respectively (see FIGS. 1 and 2).

  At the intersections and upper and lower end positions of the grid-like communication grooves 23C and 24C, suction suction holes 32 (16 each in this embodiment) penetrating the parallel inner side walls 23B and 24B in the thickness direction are formed. . Further, notches 34 and 36 formed in the range in the width direction in FIG. 1 of the communication grooves 23C and 24C are provided in the lower end central portions of the parallel inner side walls 23B and 24B.

  The communication groove 23C of the parallel inner wall 23B, the notch 34, the upper surface of the bottom wall 27, the notch 36 and the communication groove 24C of the parallel inner wall 24B are negative from the suction port 30 to the suction suction hole 32 of the parallel inner wall 24B. A pressure transmission path 40 is configured.

  The parallel inner side walls 23B and 24B and the orthogonal inner side walls 25B and 26B are provided with a plurality of types having different thicknesses and sizes, and are thicknesses corresponding to the containers 60 having different dimensions to fill the gaps around them. The size type can be selected.

  Further, as shown in FIG. 2, the orthogonal inner side walls 25B and 26B protrude between the parallel inner side walls 23B and 24B, and have stopper portions 25C and 26C that prevent the inner side walls 25B and 26B from moving inward or falling down. I have.

  The supply tray 20 can be conveyed by a conveyor 62, and as shown in FIG. 3, the supply tray 20 overlaps with the suction port 30 and can apply a negative pressure to the suction port 30. A negative pressure port 64 is provided. A negative pressure is introduced into the negative pressure port 64 from a negative pressure source 68 (see FIG. 4) via a negative pressure line 66.

  The suction head 50 of the suction head device 54 is positioned directly above the supply tray 20 when the suction tray 30 and the negative pressure port 64 overlap each other.

  The suction head 50 is detachably attached to the lower end of the negative pressure hood 52, and constitutes a suction head device 54 together with the negative pressure hood 52.

  The lower ends of the suction head 50 and the negative pressure hood 52 are elongated in a direction parallel to the parallel outer peripheral walls 23 and 24, and the suction position for sucking the syringes 12 stacked and accommodated in the container 60 and the plurality of sucked syringes 12 are sucked. It is possible to move up and down between the supply tray 20 and the take-out position separated from the upper side.

  As shown in FIG. 1, the lower end surface of the suction head 50 has suction recesses 50A formed by arranging arc-shaped recesses corresponding to the circular arc of the syringe 12 to be sucked downward and at regular intervals in the horizontal direction. I have.

  Moreover, the negative pressure in the negative pressure hood 52 is applied to the upper end of each suction recess 50A, and when the suction head 50 approaches the syringe 12 stacked in the container 60 from above, When the syringe 12 at the uppermost position is sucked up by negative pressure and sucked up, one syringe 12 is adsorbed to one arcuate recess.

  The suction head 50 is replaced corresponding to the outer diameter of the syringe to be sucked. Therefore, when adsorbing a syringe having a large outer diameter, the arrangement pitch of the arc-shaped recesses is increased.

  The negative pressure hood 52 and the suction head 50 are integrally moved up and down by an elevating device 56 (see FIG. 6).

  As shown in FIG. 2, the container 60 accommodates the syringes 12 in a state where they are stacked in a direction perpendicular to the parallel outer peripheral walls 23, 24, and has a rectangular parallelepiped shape that is approximately equal to the inner space of the supply tray 20. It is made of a bag-like container made of a resin (synthetic resin, natural resin) sheet such as a vinyl sheet. The upper end can be opened outward.

  While the supply tray 20 is being conveyed by the conveyor 62, the container 60 containing the syringe 12 is placed in the inner space 28 from above, and the suction port 30 is further moved by the conveyor 62 to the negative pressure port 64. To the position where it overlaps, and stops here.

  Next, a process of taking out the syringe 12 accommodated in the container 60 in the supply tray 20 will be described.

  As described above, the container 60 containing the syringe 12 is placed in the inner space 28 of the supply tray 20 on the conveyor 62, and at this time or thereafter, the upper end of the container 60 is opened as shown in FIG. The hanging-down portion 60A is lowered to the outside of the container 60 and is accommodated in the supply tray 20 in this state.

  When the supply tray 20 comes to the take-out position, that is, the position where the suction port 30 coincides with the negative pressure port 64, this is detected by the position sensor 72 shown in FIG. 4, and the controller 70 controls the supply tray 20 by the conveyor 62. The transportation is stopped.

  Next, based on the signal from the position sensor 72, the control device 70 opens the valve 66 </ b> A of the negative pressure line 66, and negative pressure is applied from the negative pressure port 64 to the suction port 30. The negative pressure applied to the suction port 30 is transmitted to the suction suction holes 32 of the parallel inner side walls 23B and 24B via the negative pressure transmission path 40.

  Thereby, the container 60 will be in the state adsorb | sucked by the parallel inner side walls 23B and 24B.

  Next, the lifting device 56 is driven by the control device 70, the suction head 50 is lowered together with the negative pressure hood 52, and the suction head 50 approaches the syringe 12 stacked in the container 60. When this is detected by the sensor 74, a negative pressure is applied to the negative pressure hood 52 by the control device 70, and the suction head 50 sucks air from the suction recess 50A and sucks the syringe 12 at an approaching position (see FIG. 3).

  At this time, since the curvature of the circumference of the syringe 12 and the arc-shaped recess in the suction recess 50A are substantially equal, one syringe 12 is sucked into one suction recess 50A. Further, since the syringe 12 is disposed in a direction orthogonal to the parallel inner side walls 23B and 24B, the plurality of syringes 12 are simultaneously adsorbed by the adsorption recess 50A in parallel.

  In this state, the suction head 50 is pulled up together with the negative pressure hood 52 by the lifting device 56. At this time, since the container 60 is sucked by the parallel inner side walls 23B and 24B, the container 60 is constituted by a vinyl sheet or the like. Even in this case, the suction head 50 is not sucked, including the lowering portion 60A. Further, when the remaining amount of the syringe 12 in the container 60 decreases, the peripheral wall of the container 60 tends to fall inside, but this is suppressed by the parallel inner walls 23B and 24B.

  The suction head 50 is separated from the inner space 28 and the container 60 in a state where the syringe 12 is sucked, and further moved to the side to block the negative pressure of the negative pressure hood 52, so that the syringe is moved to the next step. 12 will be supplied.

  In the above embodiment, the parallel outer peripheral walls 23 and 24 and the orthogonal outer peripheral walls 25 and 26 are respectively composed of a parallel outer wall, a parallel inner wall, an orthogonal outer wall, and an orthogonal inner wall, but the present invention is limited to this. Instead, the parallel outer peripheral walls 23 and 24 and the orthogonal outer peripheral walls 25 and 26 may have a single-layer structure.

  In this embodiment, when the size of the container 60 is changed, the parallel inner side walls 23B, 24B and the orthogonal inner side having a thickness that fills the gaps between the outer periphery and the parallel outer walls 23A, 24A and the orthogonal outer walls 25A, 26A. The walls 25B and 26B are selected and replaced.

  When the material of the container 60 is a thin resin film or the like, the container 60 may be easily deformed even if the syringes 12 are stacked and accommodated therein.

  In this case, as shown in FIG. 6, it is a quadrangular cylindrical shape composed of four plate-like bodies, with the upper and lower surfaces opened, and the four plate-like bodies surround the outer periphery of the container 60. A detachable load preventing cylinder 80 may be attached to the container 60.

  When the parallel outer peripheral walls 23 and 24 of the load collapse prevention cylinder 80 and the parallel plate-like bodies 80A and 80B are accommodated in the supply tray 20 together with the container 60, the negative pressure from the suction holes 32 for suction is absorbed. A plurality of inner suction ports 82 are formed at a position where is transmitted.

  It can be used in the step of taking out a boxed syringe in a line for sucking an injection solution into the syringe.
