As shown in FIG. 1, the static eliminator 10 of the present embodiment causes air to flow to the discharge needles arranged in a line by sending air into a ventilation path that extends long in a predetermined direction. This is a so-called bar type static eliminator. Specifically, the static eliminator 10 includes an apparatus main body 10A having a discharge needle 30 and the like, and a fan unit 10B having a fan 60.

(1) Device Main Body The device main body 10A is of a so-called DC voltage application type including a discharge needle 30 to which a positive high voltage is applied and a discharge needle 30 to which a negative high voltage is applied. Specifically, as shown in FIGS. 2 and 3, the apparatus main body 10 </ b> A includes a main body case 11 having a rod shape, more specifically, a rectangular tube shape, and a static elimination object (not shown) (for example, a circuit conveyed on a production line). Chip etc.). In the main body case 11, a plurality of (in this embodiment, 12) discharge needles 30 are arranged in a line along the longitudinal direction (the x direction in each figure; an example of “the arrangement direction of the discharge needles”). ing. A corona discharge is generated by applying a high voltage to each discharge needle 30, and positive and negative ions generated by the corona discharge are passed through each ion emission port 15 formed in the vicinity of each discharge needle 30. The static electricity is discharged by being sprayed on. 2 and 3 show a state in which the upper surface cover of the apparatus main body 10A is removed.

  In the present embodiment, as described later, a positive ion discharge needle 31 that generates positive ions when a positive high voltage is applied, and a negative ion discharge needle that generates negative ions when a negative high voltage is applied. For example, a total of 12 discharge needles 30 are arranged so that 32 are alternately positioned. A pair of positive ion discharge needles 31 and negative ion discharge needles 32 that are adjacent to each other are held by a common holder 40, and this holder 40 is removed from the main body case 11 in each of the y-directions (“direction orthogonal to the arrangement direction”). Can be attached and detached individually (see FIG. 2).

a. Main Body Case The main body case 11 is a long box-shaped base portion 12 whose one side surface and both ends in the longitudinal direction are open, and a long box shape whose one side surface facing the base portion 12 and both ends in the longitudinal direction are open. The cover 13 and a pair of caps 14 and 14 fixed so as to close both ends of the base portion 12 and the cover 13 in the assembled state. The base part 12, the cover 13, and the cap 14 are all made of resin, and in particular, the cover 13 is made of, for example, a conductive resin (for example, polycarbonate).

  A plurality of (for example, six in this embodiment) ion emission ports 15 are formed at predetermined intervals on the side wall 13A opposite to the open side of the cover 13 along the longitudinal direction x. Yes. Each ion emission port 15 is a long hole extending long along the longitudinal direction x of the main body case 11. When the static eliminator 10 is used, the surface of the side wall 13 </ b> A is a static eliminator surface directed toward the static elimination object. Further, as shown in FIG. 4, a plurality of (six in this embodiment) insulating substrates 16 as insulating members are arranged on the back surface side of the side wall 13 </ b> A corresponding to each ion emission port 15. Specifically, each insulating substrate 16 has a rectangular shape extending in the longitudinal direction x as a whole, and a C-shaped notch 16A is formed along a part (approximately two-thirds) of each ion emission port 15. Has been.

  A conductive pattern 17 is formed on each insulating substrate 16 on the side facing the rear surface of the side wall 13A. Each insulating substrate 16 is formed with through holes at both ends in the longitudinal direction x, and screws 18 are screwed into the screw holes 13E of the cover 13 through the through holes. 13 is fixed to the back side. Insulating substrates 16 adjacent to each other are electrically connected to each other through conductive patterns 17 via a heat-shrinkable signal cable 19 (for example, cross-linked polyethylene). For example, the conductor pattern of the insulating substrate 16 positioned at one end in the longitudinal direction x is electrically connected to a ground line (not shown), whereby the conductor patterns on all the insulating substrates 16 are grounded to the ground level. Thus, each conductor pattern 17 serves as a “counter electrode”.

  Further, in the cover 13, one side wall 13B of the pair of side walls 13B and 13C sandwiching the side wall 13A has an L-shaped cross section, and is formed with a step portion 13D that is one step lower than the side wall 13A. As shown in FIG. 5, a plurality (six in this embodiment) of holder removal ports 20 for attaching and detaching the holder 40 are formed in the side wall portion connecting 13 </ b> A and the stepped portion 13 </ b> D. More specifically, the holder removal port 20 has a horizontally long rectangular shape as a whole, and has portions protruding to the side wall 13A side (hereinafter referred to as “projecting portions 20A”) at positions slightly inside from both ends. When the holder 40 is attached or detached, the pair of positive ion discharge needles 31 and negative ion discharge needles 32 protruding from the holder 40 pass through the protruding portions 20A.

  FIG. 6 is a perspective view of the static eliminator showing a state in which the cover 13 and a discharge unit 41 described later are removed. As shown in FIG. 3, a hollow portion 21 extending in the longitudinal direction x is provided at the bottom of the base portion 12, and an air flow is supplied from the outside through a supply port 22 formed in one cap 14. Will be sent. A discharge unit 41 described below is provided on the partition wall 23 that partitions the cavity 21 and the upper space. The partition wall 23 is formed with an insertion hole 23 </ b> A through which a rivet 55 for fixing the holder mounting member 42 is passed and a communication hole 23 </ b> B communicating with the air output unit 53.

b. FIG. 7 is a perspective view of the discharge unit 41 showing a state in which the holder 40 is mounted on the holder mounting member 42, and FIGS. 8 and 9 show a state in which the holder 40 is detached from the holder mounting member 42. 4 is a perspective view of a unit 41. FIG.

  Each holder 40 holds a pair of positive ion discharge needles 31 and negative ion discharge needles 32 as described above. Each holder 40 has an arm so that the proximal end side of the projecting portions 43 and 43 holding the discharge needles 31 and 32 is coupled to the distal end portion by a coupling portion 44 and is folded back to the distal end portion of each projecting portion 43 and 43. The portions 45, 45 are extended, and knobs 46, 46 are provided at the tips of the arm portions 45, 45, respectively. A coupling portion 44 is interposed between the pair of knob portions 46 and 46 via a gap, and the coupling portion 44 and the knob portion 46, as shown in FIGS. 11 is exposed to the outside in a state where it is mounted on 11, and constitutes a part of the outer surface of the static eliminator 10. A locking claw portion 47 that protrudes outward is integrally formed at a position near the bending portion 46 in each arm portion 45.

  Both the knobs 46 and 46 are formed with a recess 46A into which a human fingertip can be inserted. When, for example, a thumb and an index finger are inserted and sandwiched between the arm portions 45 and 45, the arms 45 and 45 are bent inward. Thus, the distance between the locking claws 47 is reduced. The holder 40 is, for example, integrally molded by pouring resin into a mold while holding the discharge needles 31 and 32, and the needle tips of the discharge needles 31 and 32 are upward (longitudinal). The base end portion is embedded in a state of projecting downward, and projecting in the direction x and the direction orthogonal to the mounting direction y.

  The holder mounting member 42 is fixed on the partition wall 23 in the main body case 11. The holder mounting member 42 has holder locking portions 51 and 51 extending from both ends of the mounting portion 50 mounted on the partition wall 23, respectively. Insertion grooves 51A and 51A into which the arm portions 45 of the holder 40 are inserted are formed. An engagement hole 52 that engages with the locking claw portion 47 of the arm portion 51 is formed through each insertion groove 51A.

  Further, an air output portion 53 is provided between the locking portions 51 and 51 so as to penetrate the mounting portion 50. More specifically, the air output portion 53 has a cylindrical shape, and in the present embodiment, one air output portion 53 is provided for each discharge needle 30 and is arranged along the longitudinal direction x. An O-ring 54 is attached to the lower side of the air output portion 53, and the mounting portion 50 is fixed to the partition wall 23 with rivets 55, 55, for example, so that the sealing performance is maintained by the O-ring 54. Thus, the air output portion 53 communicates with the cavity portion 21 (see FIG. 3). The air flow supplied into the cavity portion 21 passes through the vicinity of each discharge needle 30 via the air output portion 53, and the ions generated by the discharge needle 30 are transferred from the ion emission port 15 to the outside. Plays a role to release. Therefore, the path from the cavity 21 to the ion emission port 15 via the air output part 53 is an example of the “ventilation path”.

  In the main body case 11, a pair of power lines L 1 and L 2 extending in the longitudinal direction x are provided with the mounting portion 50 interposed therebetween. One of the power supply lines L1 is a power supply line for applying a positive high voltage to the positive ion discharge needle 31, and the power supply line L1 is in contact with the proximal end portion of the positive ion discharge needle 31. Is electrically connected to the leaf spring 56. The other power supply line L2 is a power supply line that applies a negative high voltage to the negative ion discharge needle 32, and this power supply line L2 serves as a contact terminal that contacts the proximal end portion of the negative ion discharge needle 32. The leaf spring 57 is electrically connected.

  To attach the holder 40 to the main body case 11, as shown in FIG. 1, the holder 40 is inserted through the holder removal port 20 along the attaching / detaching direction y while sandwiching both the knobs 46 and 46 with fingers. At this time, both arm portions 45 and 45 are guided to the back side of the main body case 11 along the insertion grooves 51 </ b> A of the both locking portions 51 and 51. Thereafter, when the fingers are released, both the arm portions 45, 45 are restored and deformed, and the respective locking claws 47 are engaged with the respective engagement holes 52, whereby the holder 40 is positioned and fixed in the main body case. . At this time, the discharge needle 31 for positive ions contacts the leaf spring 56 while elastically deforming the leaf spring 56, and the discharge needle 32 for negative ions contacts the leaf spring 57 while elastically deforming the leaf spring 57. Thereby, the electrical connection between the discharge needles 31 and 32 and the leaf springs 56 and 57 can be ensured.

(2) Fan Unit The fan unit 10B has a built-in fan 60 that sends air into the cavity 21 in the apparatus main body 10A. The fan unit 10B is disposed adjacent to the apparatus main body 10A on the one side of the apparatus main body 10A in the orthogonal direction y side. Further, the fan unit 10B is connected to the apparatus main body 10A while being rotatable around the apparatus main body 10A within a predetermined range.

  FIG. 10 is an enlarged perspective view of the fan unit 10B portion, FIG. 11 is a plan view showing the inside of the fan unit 10B, and FIG. 12 is a perspective view of each component constituting the connecting portion. As shown in FIG. 10, the fan unit 10B has a rectangular box shape as a whole, and is provided in a state in which a connecting portion 61 that is rotatably connected to the apparatus main body 10A protrudes from one side surface.

  The fan unit 10B includes a power switch 63, a connector 64 to which a power cable (not shown) is connected, and an indicator lamp 65 (an end face in the arrangement direction) that is flush with the connecting portion 61. An example of “notification unit” is provided. The connector 64 is provided at a stepped portion with a surface recessed inwardly by one step from the outer surface 62 provided with the switch 63, and the tip is directed in the orthogonal direction y. As a result, the connector 64 does not protrude from the outer surface 62.

  Further, a filter cover 67 provided with a plurality of slit-like vent holes 66 is detachably provided on the surface of the fan unit 10B by an engaging claw 70 or the like. The filter cover 67 is detachable by sliding along the longitudinal direction x. Then, when the filter cover 67 is removed, as shown in FIG. 13, the filter 69 accommodated in the accommodating portion 68 is exposed, whereby the filter 69 can be replaced. Furthermore, an insertion hole 71 into which a jig (not shown), for example, can be inserted is provided on the surface of the fan unit 10B, and an operating element 72 (an example of an “operation unit”) that is rotated by the jig is provided on the back side. Is provided.

  The fan 60 has a known configuration that employs a non-contact air moving body bearing. If such a fan 60 is used, the fan can be driven to rotate more efficiently than a fan employing a bearing. In addition, since the bearing portion is non-contact, the life of the fan is long and the product life of the static eliminator 10 is extended. A lead-out pipe 74 is led out to the fan 60, and an air flow is sent out therefrom. 11 and 12, an L-shaped tube 75 (an example of a “rotating portion”) connects the outlet tube 74 and the cavity 21 of the apparatus main body 10A. One end of the L-shaped tube 75 is connected to the outlet tube 74, while the other end is connected to one end of the apparatus main body 10A. The supply port 22 ( An example of a “hollow part” is rotatably connected. As a result, the fan unit 10B can rotate around the apparatus main body 10A around the L-shaped tube 75.

  The L-shaped tube 75 is connected to the supply port 22 of the cap 14 after being inserted into a rotation restricting tube 76 (an example of a “regulator”) as shown in FIG. The rotation restricting tube 76 is for restricting the rotation range of the fan unit 10B relative to the apparatus main body 10A to a predetermined range. Specifically, the rotation restricting tube 76 has a restricting projection 77 projecting from the end face of one end addressed to the cap 14 of the apparatus main body 10A. A tapered portion 78 is continuously formed on the one end side over the entire circumference, and an O-ring 79 is fitted to the tapered portion 78. Further, a U-shaped notch 80 is formed on the other end side of the rotation restricting tube 76, and the L-shaped tube 75 is inserted into the notch 80, and a tip portion thereof is in the rotation restricting tube 76. Inserted and connected to the cap 14. Therefore, the rotation restricting tube 76 rotates together with the L-shaped tube 75.

  FIG. 14 is a front view of the cap 14 on the side to which the fan unit 10B is connected as viewed from the fan unit 10B side. The cap 14 is formed with a feed port 22 through which the tip of the L-shaped tube 75 is rotatably connected. In addition, the cap 14 has a recessed portion 83 that sinks one step around the supply port 22, and an arc-shaped regulating groove 82 is formed here. The rotation restricting tube 76 is fitted into the recess 83 at the tip while the restricting projection 77 is inserted into the restricting groove 82. At this time, the rotation restricting tube 76 is sandwiched between the cap 14 and the L-shaped tube 75 that are connected to each other. As a result, the O-ring 79 is sandwiched between the concave portion 83 of the cap 14 and the tapered portion 78 of the rotation restricting tube 76, so that the cap 14 and the L-shaped tube 75 can be rotated in a sealed state by the O-ring 79. Connected.

  Further, the rotation range of the fan unit 10 </ b> B with respect to the apparatus main body 10 </ b> A is restricted by the restriction protrusion 77 and the restriction groove 82. Specifically, in this embodiment, the rotation range is restricted so that the fan unit 10B is not positioned in front of the charge removal surface. This is to prevent the fan unit 10B from obstructing the ion emission from the ion emission port 15.

  As shown in FIG. 10, an insertion hole 84 is formed on the outer surface 62 side of the connecting portion 61, and the rotation restriction tube 76 projects from the insertion hole 84. Then, the rotation preventing cap 85 is tightened to the protruding end of the rotation restricting tube 76, whereby the connecting portion 61 is pressed more strongly against the cap 14. Thereby, the fan unit 10B can be fixed to the apparatus main body 10A at a predetermined rotation position.

  Furthermore, the electric power supplied from the connector 64 is supplied to the control board 86 in the fan unit 10B, and the apparatus main body 10A is supplied from the control board 86 via a cable 87 (only FIG. 11 is shown and is not shown in other drawings). It is supplied to a circuit board (not shown). Specifically, as shown in FIG. 11, the cable 87 is routed along the shape of the fan 60. In the fan unit 10B, an insertion hole 88 is formed through the portion facing the apparatus main body 10A, from which the tip of the cable 87 is led out and guided into the apparatus main body 10A.

  Here, a spring 89 (an example of an “urging member”) is provided in the fan unit 10B. One end of the spring 89 is fixed at a predetermined position in the fan unit 10B, and the other end is fixed to the cable 87. Has been. With such a configuration, the cable 87 is subjected to a pulling force into the fan unit 10B due to the biasing force of the spring 89, so that the pullout length of the cable 87 expands and contracts depending on the rotational position of the fan unit 10B. For example, it is possible to prevent 87 from being greatly bent outward and becoming an obstacle to ion emission from the ion emission port 15.

2. FIG. 15 is a block diagram schematically showing the electrical configuration of the fan unit 10B. The fan 60 is rotated by a drive motor 90, and the drive motor 90 outputs a pulse signal corresponding to the number of rotations per predetermined time, and this is detected by a rotation number detection circuit 91. The detection result of the rotation speed detection circuit 91 is given to the comparator 92 and also to the control circuit 93. The comparator 92 compares the detection result with the target value and feeds back a signal corresponding to the difference to the control circuit 93. Then, the control circuit 93 controls the rotation speed of the drive motor 90 so that the difference between the detection result and the target value becomes small. The volume 94 plays a role of changing the target value in accordance with the rotation of the operation element 72. Thereby, the rotational speed of the fan 60 can be adjusted. At this time, the volume 94, the comparator 92, and the control circuit 93 function as an example of the “adjustment unit”.

  Further, the control circuit 93 (an example of the “detection unit”) considers that a rotation abnormality has occurred when the rotation speed of the fan 60 falls below a predetermined threshold based on the detection result from the rotation speed detection circuit 91. The display lamp 65 is caused to execute a predetermined lighting pattern. Thereby, the operator can know that rotation abnormality has occurred.

3. Effects of the present embodiment According to the present embodiment, the fan unit 10B is provided on the side of the apparatus main body 10A in the orthogonal direction y so that the fan unit 10B does not protrude significantly in the longitudinal direction x. Further, since the fan unit 10B is configured to send air into the cavity 21 via the connecting portion 61 to one end side of the apparatus main body 10A, the fan unit 10B increases in size as the number of discharge needles 30 increases. This can be suppressed.

  The fan unit 10B is rotatable about the apparatus main body 10A. Therefore, the position of the fan unit 10B can be changed according to the installation location of the static eliminator 10. In addition, a connector 64, a switch 63, an indicator lamp 65, and an operator 72 are provided on the fan unit 10B side.
