  The support part 30 supports the receiver 1 from the lower side in a state where the engagement protrusion 34 is inserted into the engagement receiving part 1A of the receiver 1 placed on the conveyor device 5A. The conveyor device 5 </ b> A is a device that conveys the receiver 1 sent from the previous process to the vicinity of the lift-type transport device 100, and includes an engagement protrusion 1 </ b> A of the receiver 1 and an engagement protrusion of the support 30. The receiver 1 is transported to a position where 34 is engaged.

  The lift-type transfer device 100 includes a control device 6 on the outer side surface of the mast 20. The control device 6 is operated by an operator and controls the operation of the drive motor 26 that moves the slide base 40 up and down and the drive motor 11 that rotates the rotary cylinder 10.

  In the lift type transport apparatus 100 described above, the width of the rotary cylinder 10 is set larger than the width of the mast 20, and heavy objects such as the drive motors 11 and 26 are accommodated in the rotary cylinder 10, whereby the lift type transport apparatus 100. To lower the center of gravity. Therefore, even if an earthquake or the like occurs, it is possible to suppress the shaking of the upper part of the lift type transfer device 100.

  Next, with reference to FIG.3 and FIG.4, the conveyance of the receiver 1 by the lift type conveying apparatus 100 is demonstrated. 3 is a side view of the lift type transport apparatus 100, and FIG. 4 is a plan view of the lift type transport apparatus 100. As shown in FIG.

  As shown in FIG. 3, the lift type conveying apparatus 100 conveys the receiving device 1 placed on the conveyor apparatus 5A to another conveyor apparatus 5B.

  The support part 30 of the lift type conveying apparatus 100 stands by at a predetermined standby position above the conveyor apparatus 5A. After the receiver 1 is transported to the standby position of the support unit 30 by the conveyor device 5A and the engagement protrusion 1A of the receiver 1 and the engagement protrusion 34 of the support unit 30 are engaged, the drive motor of the lift type transport device 100 26 is driven forward. When the drive motor 26 is driven to rotate in the forward direction, the support portion 30 is raised as indicated by the solid line arrow in FIG. 3 while the pair of engaging protrusions 34 of the support portion 30 support the receiver 1.

  The operation of the drive motor 26 is stopped at a predetermined position where the lowermost surface of the receiver 1 is higher than the conveyor device 5B, and the raising of the support portion 30 is stopped. Thereafter, the drive motor 11 of the lift type conveying apparatus 100 is driven to rotate forward, and the support portion 30 rotates clockwise around the mast 20 as the rotating cylinder 10 rotates as shown by the broken line arrow in FIG. Turn.

  As shown in FIG. 3, when the receiver 1 supported by the support portion 30 moves to the upper position of the conveyor device 5B, the operation of the drive motor 11 is stopped and the turning of the support portion 30 is stopped. Thereafter, the drive motor 26 of the lift type transport apparatus 100 is driven in reverse, and the support portion 30 is lowered. When the receiver 1 supported by the support unit 30 is placed on the conveyor device 5B, the operation of the drive motor 26 is stopped and the lowering of the support unit 30 is stopped. The receiver 1 thus transferred is transported to the next process by the conveyor device 5B, and the support unit 30 returns to a predetermined standby position.

  By the way, in the above-mentioned lift type conveying apparatus 100, since the opening part 21 is formed in the mast 20, when the support part 30 raises / lowers or turns, there is a possibility that the dust or dust accumulated in the mast 20 may rise to the outside. There is.

  Therefore, the lift-type transfer device 100 includes an airflow control unit 50, and the airflow control unit 50 controls the airflow in front of the opening 21 of the mast 20, thereby suppressing dust generation from the mast 20.

  The airflow control unit 50 will be described with reference to FIGS. 2 and 5 to 7. FIG. 5 is a front view of the airflow control unit 50. FIG. 6 is a side view of the first passage 51 of the airflow control unit 50, and FIG. 7 is a side view of the second passage 52 of the airflow control unit 50.

  As shown in FIGS. 2 and 5, the airflow control unit 50 is disposed at a position corresponding to the opening 21, that is, in front of the opening 21 of the mast 20. The airflow control unit 50 includes a first passage 51 extending in the vertical direction, a second passage 52 disposed so as to face the first passage 51, and air (gas fluid) in the first passage 51. A supply pump (supply unit) 53 for supplying and a discharge pump (discharge unit) 54 for discharging the air in the second passage 52 are provided.

  The first passage 51 is composed of a hollow rectangular frame, and is disposed in front of the opening 21 of the mast 20 so as to pass between the pair of protrusions 43 formed on the slide base 40. The An air supply path 55 is connected to the upper portion of the first passage 51, and a supply pump 53 is installed in the air supply path 55. An open / close valve 55 </ b> A for opening and closing the air supply path 55 is installed in the air supply path 55 downstream of the supply pump 53.

  The second passage 52 is formed of a hollow rectangular frame, and includes two straight passages 52 </ b> A extending in the vertical direction on both sides of the first passage 51, and two straight passages below the first passage 51. And a communication path 52B communicating with the lower end of 52A.

  As shown in FIG. 2, the straight passage 52 </ b> A is disposed in front of the wall surface portion 27 on the mast side surface where the opening 21 is formed. The two straight passages 52 </ b> A are arranged in parallel to the outside of the protrusion 43 of the slide base 40. As shown in FIG. 5, an air discharge path 56 is connected to the upper part of the straight path 52 </ b> A, and a discharge pump 54 having a dust collecting function is installed in the air discharge path 56. An open / close valve 56 </ b> A that opens and closes the air discharge path 56 is installed in the air discharge path 56 upstream of the discharge pump 54.

  As shown in FIG. 6, the first passage 51 has an opening slit (first opening slit) 51A formed in the vertical direction on the side surface of the second passage 52 facing the linear passage 52A, and the opening width of the opening slit 51A. A pair of plate members 51B for adjustment. The opening width of the opening slit 51A can be adjusted by changing the installation interval of the pair of plate members 51B. In the present embodiment, the plate members 51B are arranged in parallel, and the opening width of the opening slit 51A is constant in the vertical direction.

  In FIG. 6, the side surface of one first passage 51 facing the straight passage 52 </ b> A of the second passage 52 is shown, but the side surface of the other first passage 51 has the same configuration. Further, the side surface of the straight passage 52A facing the first passage 51 has the same configuration, and the side surface of the straight passage 52A of the second passage 52 is formed in the vertical direction as shown in FIG. A pair of plate members 52D for adjusting the opening width of the opening slit (second opening slit) 52C and the opening slit 52C are provided.

  Next, airflow control by the airflow control unit 50 will be described with reference to FIG.

  When the transport of the receiver 1 is started by the lift type transport device 100, the control device 6 (see FIG. 1) drives the supply pump 53 and the discharge pump 54, and the on-off valves 55A and 56A are opened.

  When the supply pump 53 is driven, air is supplied into the first passage 51 through the air supply path 55. The air supplied into the first passage 51 is discharged to the outside through the opening slit 51A whose opening width is adjusted by the plate member 51B. At this time, since the discharge pump 54 is also driven, the air discharged from the first passage 51 and the outside air are straightened through the second passage 52 through the opening slit 52C whose opening width is adjusted by the plate member 52D. It is sucked into the passage 52A.

  As a result, an air flow is generated between the first passage 51 and the straight passage 52A of the second passage 52 across the front of the opening 21 of the mast 20 as shown by the arrow in FIG. Therefore, even if the slide base 40 moves up and down or the rotating cylinder 10 rotates and dust or dust rises in the mast 20, the passage of the opening 21 such as dust is blocked by the generated air flow. Dust and the like that have risen in the mast 20 are sucked into the linear passage 52A together with air, and are removed when passing through the discharge pump 54 having a dust collecting function.

  Moreover, in the lift type conveying apparatus 100, as shown in FIGS. 1 and 5, the upper sheet 61 that covers the opening 21 above the slide base 40 inside the mast 20 and the opening 21 below the slide base 40. A lower sheet 62 is provided to increase the dust generation suppressing effect during operation of the transport device.

  The upper sheet 61 can be wound and unwound by a winding roll 63 disposed on the upper portion of the mast 20, and the tip of the upper sheet 61 is attached to the upper surface of the protruding portion 43 of the slide base 40. The lower sheet 62 can be wound and unwound by a winding roll 64 disposed at the lower part of the mast 20, and the tip of the lower sheet 62 is attached to the lower surface of the protruding portion 43 of the slide base 40. Therefore, even if the slide base 40 moves up and down, the opening 21 above the slide base 40 can be covered with the upper sheet 61, and the opening 21 below the slide base 40 can be covered with the lower sheet 62. . Thus, since the opening part 21 of the mast 20 is covered with the upper sheet 61 and the lower sheet 62, it is possible to suppress dust and the like that has risen in the mast 20 from being scattered outside.

  According to the lift type conveying apparatus 100 described above, the following effects can be obtained.

  The lift-type transfer device 100 includes a first passage 51 </ b> A including a first passage 51 having an opening slit 51 </ b> A and a second passage 52 having an opening slit 52 </ b> C in front of the mast side surface where the opening 21 is formed. By supplying air into the interior and discharging the air from the second passage 52, an air flow is generated across the front of the opening 21 between the first passage 51 and the straight passage 52A. Therefore, even if the slide base 40 moves up and down or the rotating cylinder 10 rotates and dust or dust rises in the mast 20, the generated air flow can block the passage of the dust and the like through the opening 21, and the dust And the like can be prevented from scattering to the outside.

  The straight passage 52A of the first passage 51 and the second passage 52 is provided with plate members 51B and 52D for adjusting the opening widths of the opening slits 51A and 52C. Since the opening widths of the opening slits 51A and 52C can be changed by adjusting the distance between the plate members 51B and 52D, it is possible to adjust the strength of the air flow generated between the first passage 51 and the straight passage 52A. it can. When the plate members 51B and 52D are arranged in parallel in the vertical direction as in this embodiment, the air discharged from the opening slit 51A of the first passage 51 is connected to the connection position of the air supply passage 55 and the first passage 51 (air supply position). ) And the air sucked from the opening slit 52C of the straight passage 52A of the second passage 52 decreases as the distance from the connection position (air discharge position) between the air discharge passage 56 and the straight passage 52A increases. For this reason, the air flow generated at the lower ends of the first passage 51 and the straight passage 52A becomes weaker, and the strength of the generated air flow becomes uneven in the vertical direction. In such a case, the distance between the plate members 51B is set so that the opening width of the opening slit 51A increases as the distance from the air supply position increases, and the opening width of the opening slit 52C increases as the distance from the air discharge position increases. By setting the interval between the plate members 52D, the strength of the generated air flow can be made uniform in the vertical direction. Thereby, scattering of dust etc. from the mast 20 can be further suppressed.

  Dust and the like that have risen in the mast 20 are sucked into the linear passage 52A together with air and removed when passing through the discharge pump 54 having a dust collecting function. Therefore, it is difficult for dust and dirt to accumulate in the mast 20, and it is possible to suppress the occurrence of dust and the like.

  Furthermore, the lift-type transport device 100 includes an upper sheet 61 that covers the opening 21 above the slide base 40 and a lower sheet 62 that covers the opening 21 below the slide base 40 inside the mast 20. Scattering of dust and the like from the mast 20 can be further suppressed.

(Second Embodiment)
With reference to FIG. 8, the lift type conveying apparatus 100 in 2nd Embodiment is demonstrated. FIG. 8 is a cross-sectional view of the mast 20 of the lift type transfer device 100.

  The lift type transport apparatus 100 of the second embodiment has substantially the same configuration as that of the first embodiment, but differs in that the support portion 30 is configured to be rotatable with respect to the slide base 40. Hereinafter, the difference will be mainly described.

  The mounting plate 44 of the slide base 40 is formed with a support portion 44A that penetrates in the horizontal direction and rotatably supports the shaft portion 31 of the support portion 30. The rear end of the shaft portion 31 supported by the support portion 44 </ b> A protrudes from the back surface of the mounting plate 44. A link 35 is attached to the rear end of the shaft portion 31.

  The link 35 is a crank-shaped connecting member. The front end 35A of the link 35 is fixed to the center of the rear end of the shaft portion 31, and the rear end 35B of the link 35 is slidably engaged with a guide groove (groove portion) 70 provided on the front surface of the first passage 51 of the airflow control unit 50. Match.

  The guide groove 70 will be described with reference to FIG. FIG. 9 is a front view of the first passage 51 of the airflow control unit 50.

  As shown in FIG. 9, the guide groove 70 extends upward from the upper end of the first linear groove 71 and the first linear groove 71 and the second linear groove 72 provided in the lower part and the upper part of the first passage 51. A first inclined groove 73; and a second inclined groove 74 connecting the upper end of the first inclined groove 73 and the lower end of the second linear groove 72.

  The first straight groove 71 and the second straight groove 72 are extended in the vertical direction so as to be orthogonal to the axis of the shaft portion 31 of the support portion 30.

  The first inclined groove 73 is inclined with respect to the vertical direction so that the upper part is away from the axial center of the shaft part 31 of the support part 30 as the upper part is higher. In addition, the second inclined groove 74 is inclined with respect to the vertical direction so that the lower portion is away from the axis of the shaft portion 31 of the support portion 30.

  With reference to FIG. 9, the rotation of the support portion 30 when the receiver 1 is transported upward will be described.

  When the support portion 30 is at a predetermined standby position, the rear end 35 </ b> B of the link 35 is located at the lower end of the first linear groove 71. At this time, the shaft portion 31 of the support portion 30 to which the front end 35 </ b> A of the link 35 is fixed is located immediately below the rear end 35 </ b> B of the link 35.

  When the drive motor 26 is driven to raise the support portion 30, the rear end 35 </ b> B of the link 35 moves upward along the first linear groove 71 as the shaft portion 31 of the support portion 30 rises. When the first linear groove 71 is moving, the shaft portion 31 of the support portion 30 does not rotate.

  When the support portion 30 is raised and the rear end 35B of the link 35 starts to move from the first linear groove 71 along the first inclined groove 73, the rear end 35B of the link 35 is separated from the axis of the shaft portion 31. start. As a result, the shaft portion 31 fixed to the tip 35 </ b> A of the link 35 rotates clockwise, and the support portion 30 starts to rotate around the shaft portion 31. When the rear end 35B of the link 35 moves to the upper end of the first inclined groove 73, the rear end 35B of the link 35 is farthest from the axis of the shaft portion 31, and the link 35 is in a horizontal state. Thereby, the support part 30 rotates 90 degrees from the state which was in the standby position, and the receptacle 1 will be in a lying state. In addition, the engagement protrusion 34 of the support part 30 and the engagement receiving part 1A of the receiver 1 are engaged so that the support part 30 does not fall even if the support part 30 rotates and the receiver 1 falls sideways.

  When the support portion 30 is further raised and the rear end 35B of the link 35 starts to move from the first inclined groove 73 along the second inclined groove 74, the rear end 35B of the link 35 becomes lower than the shaft portion 31. Since it begins to approach the axial center of the shaft part 31, the shaft part 31 further rotates. When the rear end 35B of the link 35 reaches the upper end of the second inclined groove 74, the support portion 30 rotates 180 ° from the state where it is in the standby position, and the receiver 1 is in the inverted state.

  When the rear end 35B of the link 35 moves from the second inclined groove 74 to the second linear groove 72, the rear end 35B of the link 35 moves on a line orthogonal to the axis of the shaft portion 31 even if the support portion 30 is raised. Therefore, the support part 30 does not rotate. Therefore, the receiver 1 supported by the support part 30 rises in the inverted state.

  According to the lift type conveying apparatus 100 described above, the following effects can be obtained.

  In the lift-type transport device 100, the rear end 35 </ b> B of the link 35 moves along the guide groove 70 when the support unit 30 moves up and down, so that the shaft portion 31 fixed to the front end 35 </ b> A of the link 35 is moved with respect to the slide base 40. Can be rotated. Thereby, the support part 30 can be rotated without providing an actuator or the like, and the receiver 1 supported by the support part 30 can be rotated with a relatively simple configuration.

  Further, in the lift type transport device 100, the receiver 1 can be rotated 180 ° by moving the rear end 35B of the link 35 from the first linear groove 71 to the second linear groove 72 when the support portion 30 is raised. . Therefore, for example, when the medicine outlet of the receiver 1 is installed on the upper surface, the medicine outlet can be turned downward by turning the receiver 1 in an inverted state, and stored in the receiver 1 in the next step. It is possible to easily drop the supplied medicine.

  Note that the present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  The lift-type transport device 100 of the first and second embodiments is a device that transports the receiver 1 that stores the medicine, but transports the receiver in the food field and the chemical field in which scattering of dust and the like becomes a problem. It is good also as an apparatus to do.

  Moreover, in the lift type conveying apparatus 100 of 1st and 2nd embodiment, although it comprised so that the slide base 40 might be raised / lowered by the ball screw mechanism comprised from the screw shaft 23, the nut part 45, etc., inside the mast 20 A drive sprocket and a driven sprocket may be arranged, a chain or a belt provided with the slide base 40 may be wound around these sprockets, and the drive sprocket may be driven by the drive motor 26 so that the slide base 40 is moved up and down.

  The present invention can be applied to a transport device that transports a transported object.
