[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] 1 and 2 show a conveying system 10. The conveying system 10 conveys an object 11, and includes a first work table 12 and a second work table 13 arranged side by side, a conveying device 14 disposed on the side of the second work table 13 in a first direction X, and an unloading conveyor 15 that unloads the object 11 sent from the conveying device 14 in a second direction Y intersecting the first direction X.

[0011] The transported object 11 is, for example, a container, and an operator places an item inside or removes an item from the container on a first workbench 12, and then moves the item to a second workbench 13 and pushes it in a first direction X toward a transport device 14.

[0012] The second work table 13 is provided with a guide 17 which regulates the side position in the movement direction of the transported item 11 being moved from the first work table 12 to the second work table 13, and guides the transported item 11 being pushed from the second work table 13 into the transport device 14 into the transport area of ​​the transport device 14.

[0013] In a first conveying state in the first direction X, the conveying device 14 conveys the object 11 pushed out from the second worktable 13 to a predetermined conveying position in the first direction X, and then switches the conveying direction to a second conveying state in the second direction Y, and conveys the object 11 in the second direction Y to send it out to the discharge conveyor 15. The first conveying state in the first direction X becomes a standby state.

[0014] 1 to 5 show the conveying device 14. The conveying device 14 uses an orthogonal converter that can switch between a first conveying state in a first direction X and a second conveying state in a second direction Y. The conveying device 14 includes a pair of frames 20 facing each other in the second direction Y, a plurality of rollers 21 that are first direction rotating bodies arranged at a predetermined interval in the first direction X between the pair of frames 20, a plurality of belts 22 that are second direction rotating bodies arranged between adjacent rollers 21, and a mechanism unit 23 that connects the pair of frames 20 and raises and lowers the plurality of belts 22 relative to the rollers 21. Note that the second direction rotating bodies can be, in addition to belts, chains, rollers, etc.

[0015] The frame 20 is long and formed with a generally C-shaped cross section (lip groove shape) with the middle of the upper and lower edges of the outer surface being open.

[0016] A rotational force is transmitted from a motor to the rollers 21, which are rotated together to transport the article 11 in the first direction X.

[0017] The belts 22 are supported by a plurality of pulleys so as to be able to rotate, and are rotated together by the torque transmitted from a motor.

[0018] The mechanism 23 lowers the belt 22 below the rollers 21 in a first conveying state in which the transported object 11 is conveyed in a first direction X, and raises the belt 22 above the rollers 21 in a second conveying state in which the transported object 11 is conveyed in a second direction Y. The belt 22 is stopped from being driven when lowered, and can be driven when raised. In other words, the rollers 21 support and convey the transported object 11 in the first conveying state, and the belt 22 supports and conveys the transported object 11 in the second conveying state.

[0019] In addition, the conveying device 14 is provided with a plurality of sensors 30 for detecting the conveyed object 11, which is an object inside the conveying area of ​​the conveying device 14. The sensors 30 include a first sensor 30a for detecting the conveyed object 11 pushed from the conveying device 14 through the second worktable, a second sensor 30b for detecting the conveyed object 11 conveyed to a predetermined conveying position in the first direction X on the conveying device 14, and a third sensor 30c for detecting the conveyed object 11 sent out from the conveying device 14 to the discharge conveyor 15.

[0020] 7 and 8, the sensor 30 is provided in a rectangular parallelepiped shape and has a detection surface 31 on one side. The sensor 30 detects the transported object 11, for example, by emitting detection light from the detection surface 31 and receiving the reflected light reflected by the transported object 11. The sensor 30 is provided with a pair of mounting holes 32 penetrating a side surface intersecting the detection surface 31. The detection surface 31 of the sensor 30 has a detection unit that acts on an object such as the transported object 11 to enable object detection, and this detection unit corresponds to a light-projecting unit in a photoelectric sensor, an imaging unit in an optical sensor, or an irradiation unit such as ultrasonic wave, infrared light, or laser in a distance sensor.

[0021] 1 to 6, a sensor mounting device 40 is used to mount the sensor 30 on the transport device 14. The sensor mounting device 40 includes a first sensor mounting device 41 that mounts the first sensor 30a and the second sensor 30b on one side of the transport device 14 along the first direction X and on one frame 20 on the upstream side in the second direction Y, and a second sensor mounting device 42 that mounts the third sensor 30c on one side of the transport device 14 along the second direction Y, straddling the downstream ends of the pair of frames 20 in the first direction X. The first sensor mounting device 41 and the second sensor mounting device 42 have basically the same configuration, except that their lengths correspond to the lengths of the sides of the transport device 14.

[0022] The sensor mounting device 40 comprises a pair of support members 45 as supports attached to both longitudinal ends of the frame 20, a sensor mounting body 46 and a cover 47 supported above the frame 20 by the pair of support members 45, and a sensor bracket 48 for mounting the sensor 30 to the sensor mounting body 46.

[0023] The support member 45 supports the sensor mounting body 46 in the longitudinal direction along the conveying direction of the conveyed object 11. The support member 45 is elongated and longer than the vertical height dimension of the frame 20, and has a substantially U-shaped horizontal cross section. The support member 45 has a side portion 51 and both edge portions 52, 53 bent from both sides of the side portion 51, with an opening between the both edge portions 52, 53.

[0024] The support member 45 of the first sensor mounting device 41 is mounted by attaching one side edge 52 to a mounting plate 54 arranged inside the frame 20 with a plurality of bolts 55, thereby sandwiching the upper and lower edges of the frame 20 between the mounting plate 54 and the edge 52 of the support member 45. The pair of support members 45 are mounted to the frame 20 so that the openings between the edges 52, 53 on both sides face each other. The support members 45 can be mounted at any position in the longitudinal direction of the frame 20.

[0025] The support member 45 of the second sensor mounting device 42 is attached to the frame 20 via a spacer 56. The spacer 56 is fixed to an end of the frame 20 by a spacer bracket 57 attached to the inside of the frame 20. The support member 45 is attached to the spacer 56 by a bolt 55. Note that the support member 45 may be attached to the spacer bracket 57 without using the spacer 56.

[0026] The support member 45 may be attached to the middle of the frame 20 in the longitudinal direction, and may support the sensor mounting body 46 in the longitudinal direction along the conveying direction of the transported object 11. In this case, the support member 45 may have a structure different from the support structure described above, and the number of support members used may be multiple or one.

[0027] The sensor mounting body 46 is a square prism-shaped rail with dovetail grooves 59 on the four peripheral surfaces along the longitudinal direction. Both longitudinal ends of the sensor mounting body 46 are inserted into the upper sides of the pair of support members 45 from above, and a bolt 60 passing through an edge 52 on one side of the support member 45 is screwed into a nut member 61 (see FIG. 6) inserted into the groove 59 on one side of the sensor mounting body 46, so that the sensor mounting body 46 is mounted in a spanning state between the pair of support members 45. The sensor mounting body 46 has a length direction in the conveying direction of the conveyed object 11, and is supported in a horizontal position approximately parallel to the upper surface of the frame 20 at a height position spaced above the frame 20. The sensor 30 is attached to the lower surface side of the sensor mounting body 46 by a sensor bracket 48 and is disposed between the opposing surfaces of the pair of support members 45. In this state, the sensor 30 is located between the frame 20 and the sensor mounting body 46 and is attached so as to be suspended from the sensor mounting body 46.

[0028] The cover 47 is formed to have a length corresponding to the width between the pair of support members 45. The cover 47 integrally includes an upper surface portion 63 arranged on the upper surface side of the sensor mounting body 46, an outer side surface portion 64 arranged on the outside between the pair of support members 45 that are on the outside with respect to the transport device 14, and an inner side surface portion 65 arranged on the inside between the pair of support members 45 that are on the inside facing the transport area of ​​the transport device 14. Note that the outer side surface portion 64 and the inner side surface portion 65 are not in contact with the sensor 30 so that an impact on the outer side surface portion 64 or the inner side surface portion 65 does not directly act on the sensor 30.

[0029] The upper surface portion 63 covers the upper surface sides of the pair of support members 45 and the sensor mounting body 46. The upper surface portion 63 is attached to the sensor mounting body 46 by screwing bolts 66, which are inserted through both ends, into nut members 67 (see FIG. 6), which are inserted into grooves 59 on the upper surface side of the sensor mounting body 46. The upper surface portion 63 is indirectly supported by the pair of support members 45 via the sensor mounting body 46.

[0030] The outer surface portion 64 is bent downward from the outer edge of the upper surface portion 63, and covers the entire outer width area between the pair of support members 45. The outer surface portion 64 covers the outside of the upper sides of the pair of support members 45, the sensor mounting body 46, and the sensor 30 that is attached to the lower surface side of the sensor mounting body 46 and disposed between the opposing surfaces of the pair of support members 45.

[0031] An attachment groove 68 having a downward groove opening is provided on the underside of both ends of the outer surface portion 64, and both ends of the outer surface portion 64 are attached to a pair of support members 45 by tightening a bolt 69 that passes through this attachment groove 68 and the outer edge portion 53 of the support member 45 and a nut 70 that screws onto the inserted bolt 69 (see Figure 6).

[0032] The lower end of the outer side surface portion 64 is disposed below the detection portion of the sensor 30 attached to the underside of the sensor mounting body 46 and above the frame 20. A folded portion 71 is provided from the lower portion of the outer side surface portion 64 so as to be parallel to the upper surface portion 63 and protruding into the area below the sensor 30.

[0033] The inner surface portion 65 is bent downward from the inner edge of the upper surface portion 63 and covers the entire inner width area between the pair of support members 45. The inner surface portion 65 covers the upper sides of the pair of support members 45, the sensor mounting body 46, and the inside of the bolts 60 that attach the sensor mounting body 46 to the pair of support members 45.

[0034] The inner surface portion 65 has a contact surface portion 72 provided in a flat shape along the conveying direction (first direction X or second direction Y) of the transported object 11, and inclined surface portions 73 provided at both longitudinal ends of this contact surface portion 72.

[0035] The contact surface portion 72 extends in the length direction of the sensor mounting body 46, and can guide the transported object 11 that comes into contact with the contact surface portion 72 in the transport direction. The lower end positions of the contact surface portion 72 and the inclined surface portion 73 are located above the detection portion of the sensor 30 attached to the underside of the sensor mounting body 46, at a height that does not impede detection by the sensor 30. A folded portion 74 is provided from the lower portion of the contact surface portion 72, which is folded back so as to be parallel to the upper surface portion 63. The inclined surface portion 73 is inclined from the contact surface portion 72 toward the outside of the transport area of ​​the transport device 14.

[0036] 6 to 8 show the sensor bracket 48. The sensor bracket 48 includes a mounting base 77 that is attached to the sensor mounting body 46, a sensor mounting portion 78 that is bent and protrudes from a first side of the mounting base 77 in a direction intersecting the mounting base 77, and a protruding portion 79 that is bent and protrudes from a second side opposite the first side of the mounting base 77 in a direction intersecting the mounting base 77 and faces the sensor mounting portion 78 in parallel.

[0037] The mounting base 77 is provided with a mounting hole 81 through which one bolt 80 for mounting to the sensor mounting body 46 is inserted. The mounting hole 81 is formed as an elongated hole that is long in a direction parallel to the surface of the sensor mounting part 78, and when the sensor bracket 48 is rotated in the horizontal direction, the sensor bracket 48 can be positioned within the width of the sensor mounting body 46 by adjusting the position of the elongated hole relative to the bolt 80 and shifting the position of the sensor bracket 48 relative to the bolt 80 so that the mounting base 77 does not protrude outside the sensor mounting body 46. The mounting hole 81 can also be a round hole instead of an elongated hole. The bolt 80 is screwed into a nut member 82 inserted and disposed in a groove portion 59 on the underside of the sensor mounting body 46, and fixes the sensor bracket 48 to the underside of the sensor mounting body 46.

[0038] When fixing the sensor bracket 48 to the sensor mounting body 46, the bolt 80 inserted through the sensor bracket 48 is screwed into the nut member 82 in the groove portion 59 of the sensor mounting body 46 but is not tightened, so that the sensor bracket 48 is moved to an arbitrary position in the longitudinal direction of the sensor mounting body 46 to adjust the horizontal orientation of the detection surface 31 (sensor optical axis) of the sensor 30. After the adjustment, the bolt 80 is tightened to fix the sensor bracket 48 to the sensor mounting body 46. When tightening the bolt 80, the sensor bracket 48 may rotate together with the bolt 80, which may cause the adjustment position of the horizontal orientation of the sensor 30 to shift; however, as shown in FIG. 8, a tool 83 such as a wrench can be engaged with the sensor mounting portion 78 and the protrusion 79 to prevent rotation. In other words, the protrusion 79 comes into contact with the back of the U-shaped opening of the wrench head and the sensor bracket 48 can be held with the wrench by clamping the mounting base 77 on both sides, so that the horizontal rotation angle of the sensor bracket 48 is maintained in the direction of the wrench head.Even if the bolt 80 is tightened in this state, the adjusted position of the horizontal orientation of the sensor 30 does not shift, and the sensor bracket 48 can be fixed to the sensor mounting body 46.

[0039] The sensor mounting portion 78 is provided with a pair of mounting holes 84 for mounting the sensor 30. The pair of mounting holes 84 are formed as arc-shaped elongated holes at the same pitch as the pair of mounting holes 32 of the sensor 30, and the sensor 30 can be mounted by adjusting the vertical orientation of the detection surface 31 (sensor optical axis).

[0040] The assembly procedure for the sensor mounting device 40 will be described below. First, the support member 45 is fixed to the frame 20. For the second sensor mounting device 42, the support member 45 is fixed to the frame 20 via a spacer 56.

[0041] Next, the sensor mounting body 46 is fixed in a spanning state between the upper portions of the pair of support members 45 .

[0042] Next, the sensor bracket 48 to which the sensor 30 is attached is fixed to the underside of the sensor mounting body 46. At this time, as described above, in a provisionally fixed state in which the bolt 80 inserted through the sensor bracket 48 is screwed into the nut member 82 in the groove portion 59 of the sensor mounting body 46 but is not tightened, the position of the sensor bracket 48 in the longitudinal direction of the sensor mounting body 46 is adjusted, the horizontal direction of the detection surface 31 of the sensor 30 is adjusted, and after the adjustment, the bolt 80 is tightened to fix the sensor bracket 48 to the sensor mounting body 46. Note that the sensor mounting body 46 may be fixed between the upper portions of the pair of support members 45 in a state in which the sensor bracket 48 is provisionally fixed to the sensor mounting body 46 in advance.

[0043] Next, with the bolts fixing the sensor 30 to the sensor bracket 48 loosened, the vertical orientation of the detection surface 31 of the sensor 30 is adjusted, and after adjustment, the bolts are tightened to fix the sensor 30 to the sensor bracket 48.

[0044] Next, the cover 47 is placed over the sensor mounting body 46 , and both ends of the upper surface portion 63 are fixed to the sensor mounting body 46 by bolts 66 , and both ends of the outer surface portion 64 are fixed to the support member 45 by bolts 69 .

[0045] In the sensor mounting device 40 assembled in this manner, the sensor 30 is disposed between and covered by the opposing surfaces of the pair of support members 45, the upper side of the sensor 30 is covered by the sensor mounting body 46 and the upper surface portion 63 of the cover 47, and the outside of the sensor 30 is covered by the outer surface portion 64 of the cover 47. Since the lower end of the inner surface portion 65 (contact surface portion 72, inclined surface portion 73 and folded portion 74) of the cover 47 is disposed above the sensor 30, the detection surface 31 on the inside of the sensor 30 faces the conveying area of ​​the conveying device 14 without being covered by the cover 47, enabling detection of the conveyed object 11.

[0046] Next, the operation of the transport system 10 will be described.

[0047] After an operator places contents in the transported object 11, which is a container, the object is pushed from the second work table 13 in the first direction X toward the transport device 14. Note that the movement of the transported object 11 from the second work table 13 toward the transport device 14 may be performed using a pusher that moves in the first direction X, or the second work table 13 may be configured as a conveyor and driven to transport the object.

[0048] During standby, the conveying device 14 is in a first conveying state in a first direction X in which the belt 22 is lowered below the rollers 21, and the rollers 21 are rotating or stopped.

[0049] When the transported object 11 is pushed out from the second worktable 13 toward the transport device 14, the first sensor 30a detects the transported object 11, and if the rollers 21 are stopped, they rotate to transport the transported object 11 in the first direction X. At this time, the contact surface 72 of the inner side surface 65 of the cover 47 of the first sensor mounting device 41 functions as a guide to guide the transport of the transported object 11 in the first direction X.

[0050] When the transported object 11 is transported to a predetermined transport position on the transport device 14 and the second sensor 30b detects the transported object 11, the rotation of the rollers 21 is stopped. At this time, the transported object 11 may be stopped by abutting against the contact surface 72 of the inner side surface 65 of the cover 47 of the second sensor mounting device 42, or may be stopped at a predetermined transport position where it does not abut against the contact surface 72 of the inner side surface 65 of the cover 47 of the second sensor mounting device 42, and when it overruns the predetermined transport position, it may be stopped by abutting against the contact surface 72 of the inner side surface 65 of the cover 47 of the second sensor mounting device 42, with the contact surface 72 of the inner side surface 65 of the cover 47 of the second sensor mounting device 42 functioning as a stopper.

[0051] After the rotation of the rollers 21 is stopped, the conveying device 14 switches from a first conveying state in the first direction X to a second conveying state in the second direction Y. The multiple belts 22 rise from between the rollers 21, and the multiple belts 22 lift the conveyed object 11 upward from the rollers 21. The belts 22 then rotate, conveying the conveyed object 11 in the second direction Y and sending it out to the discharge conveyor 15, which then conveys it downstream.

[0052] When the third sensor 30c detects that the transported object 11 has been sent from the transport device 14 to the discharge conveyor 15, the belt 22 stops rotating and is lowered below the rollers 21, returning to the first transport state during standby.

[0053] Furthermore, when a worker passes along the side of the conveying device 14 of the conveying system 10 and the worker or an item being moved by the worker approaches the conveying device 14, the worker or the item may come into contact with the outer surface portion 64 of the cover 47, but will not come into contact with the sensor 30 which is positioned between the opposing surfaces of a pair of support members 45 and covered by the cover 47, and there will be no misalignment of the sensor 30.

[0054] As described above, in the sensor mounting device 40, the sensor mounting body 46 is positioned along the length in the conveying direction of the transported object 11 by the support member 45 attached to the frame 20 of the conveying device 14, the sensor 30 is installed on this sensor mounting body 46, and the sensor 30 installed on the sensor mounting body 46 is covered by the outer surface portion 64 of the cover 47 arranged on the outside of the conveying device 14, so that workers or objects passing by the side of the conveying device 14 can be prevented from coming into contact with the sensor 30 and the orientation of the sensor 30 can be prevented from shifting due to external forces.

[0055] Furthermore, in the sensor mounting device 40, the sensor 30 is positioned between the opposing surfaces of a pair of support members 45 attached to the frame 20 of the conveying device 14, and the outside between the pair of support members 45 is covered by the outer surface portion 64 of the cover 47, thereby reliably preventing contact with the sensor 30 from outside.

[0056] In addition, the cover 47 has an inner surface portion 65 that is positioned inward toward the conveying area of ​​the conveying device 14, and is provided with a contact surface portion 72 that can be contacted by the conveyed object 11 while enabling object detection by the sensor 30.Therefore, the cover 47 can serve as both a guide member and a stopper member, guiding the movement of the conveyed object 11 being conveyed by the conveying device 14 or stopping the conveyance of the conveyed object 11.

[0057] The contact surface portion 72 extends in the length direction of the sensor mounting body 46, and therefore can guide the transported article 11 that comes into contact with the contact surface portion 72 in the transport direction.

[0058] In addition, since the cover 47 is integrally provided with the upper surface portion 63, the outer surface portion 64 and the contact surface portion 72 (the inner surface portion 65), it can be easily attached by simply placing the cover 47 over the sensor mounting body 46 attached between a pair of support members 45 from above, and it is possible to prevent the sensor 30 from shifting in direction, and to ensure a guide function and a stopper function.

[0059] Furthermore, since the lower portion of the outer surface portion 64 of the cover 47 is disposed below the detection portion of the sensor 30, contact between the sensor 30 and an operator, an object, or the like can be reliably prevented.

[0060] In addition, since the inner surface portion 65 of the cover 47 is positioned above the detection portion of the sensor 30, the detection of the sensor 30 is not hindered, and since the contact surface portion 72 of the inner surface portion 65 contacts the side of the transported object 11 at a position above the transport surface of the transport device 14, the movement of the transported object 11 can be guided or stopped in a stable posture.

[0061] Furthermore, even in a structure in which sensor bracket 48 is attached to sensor mounting body 46 with a single bolt 80, by providing a protrusion 79 on sensor bracket 48, a tool 83 such as a wrench can be engaged with sensor mounting portion 78 and protrusion 79 of sensor bracket 48 to prevent rotation. Therefore, even if bolt 80 is tightened in this state, the horizontal orientation adjustment position of sensor 30 will not shift, and sensor bracket 48 can be fixed to sensor mounting body 46.

[0062] Incidentally, as long as cover 47 has at least outer surface portion 64, it is possible to prevent sensor 30 from being displaced due to external forces, and therefore cover 47 does not need to have top surface portion 63 and inner surface portion 65.

[0063] Further, the sensor mounting device 40 is not limited to an orthogonal changeover machine, but can also be applied to a conveying device such as an accumulation conveyor that detects the conveyed object 11 and controls the conveying.

[0064] Although the embodiment of the present invention and its modified examples have been described above, various combinations of configurations, partial omissions, substitutions and modifications are also possible. [Explanation of symbols]
