The main body side planetary gear mechanisms 12 and 12 have a planetary gear 40 (main body side planetary gear) and an internal gear 41 (main body side internal gear) on the outer peripheral portions of the shaft portions 30 and 30 of the rotary shafts 27 and 27 functioning as sun gears. ). The internal gear 41 is arranged at a position adjacent to the closing members 15, 15 and is fixed to the inner peripheral wall of the cylindrical body 10. The planetary gear 40 is a gear that meshes with both the internal gear 41 and the rotating shaft 27. The planetary gear 40 can rotate (revolve) around the rotation shaft 27 along the inner periphery of the internal gear 41. The planetary gear 40 can be rotated (rotated) around a pin 45 inserted through a through hole 43 provided in the shaft center portion.

In the power transmission member 50, the support shaft 17 is inserted into the shaft insertion hole 53, and an end portion (side connection portion 54 side) opposite to the main body side connection portion 51 protrudes from the end portion of the cylindrical body 10 to the outside. ing. The power transmission member 50 is mounted so as to be relatively rotatable with respect to the cylindrical body 10 through bearings 57 and 57 attached to through holes 55 and 55 provided at axial positions of the closing members 15 and 15. Yes.

  The power transmission member 50 has an external gear shape in which a tooth portion 60 is formed on the outer peripheral surface of a portion (side connection portion 54) that protrudes toward the outside of the cylindrical body 10. The power transmission member 50 is aligned with the support shaft 17 and functions as a sun gear of the side planetary gear mechanism 70 built in the side rollers 3 and 3.

  As shown in FIG. 1, the side rollers 3, 3 are in a space formed by attaching blocking members 72, 73 to a cylinder 71 having a larger opening diameter than the cylinder 10 of the main body side roller 2. The side planetary gear mechanism 70 and the side carrier 74 are built in. The closing member 72 is a member that closes the opening portion of the cylindrical body 71 on the main body side roller 2 side, and has an insertion hole 75 through which the power transmission member 50 can be inserted. The closing member 73 is a member that closes the opening portion on the other end side of the cylindrical body 71, and an insertion hole 76 through which the support shaft 17 can be inserted is provided at the center. As shown in FIG. 1, the support shaft 17 crosses the cylindrical body 71, and both ends are supported by bearings 68 and 68 attached to the closing members 73 and 73, and from the insertion hole 76 to the outside of the cylindrical body 71. Protrusively toward. Thus, the side rollers 3 and 3 are supported so as to be rotatable relative to the support shaft 17.

  The side planetary gear mechanism 70 employs a power transmission member 50 inserted through the insertion hole 75 of the closing member 72 as a sun gear, as shown in FIGS. 1 and 2, and a planetary gear 77 (side Side planetary gears) and internal gears 78 (side side internal gears) are arranged. The internal gear 78 is fixed to a portion of the inner peripheral surface of the cylinder 71 that is unevenly distributed on the closing member 72 side. The planetary gear 77 is a gear that meshes with both the internal gear 78 and the tooth portion 60 provided on the outer periphery of the insertion hole 75. The planetary gear 77 can rotate (revolve) the outer periphery of the power transmission member 50 (sun gear) along the inner periphery of the internal gear 78.

The arm portion 83 is provided with a pin mounting hole 87 into which the pin 81 can be mounted, and the planetary gear 77 is rotatably mounted (rotatable) via the pin 81 inserted into the pin mounting hole 87. ing.

  On the other hand, the side carrier 74 has the support shaft 17 passing through the center of the carrier body 82, and is attached to the support shaft 17 so as not to rotate by a key 84 inserted into the boss portion 17b of the support shaft 17. ing. Therefore, the planetary gear 77 attached to the side carrier 74 is in a state in which the outer periphery of the tooth portion 60 of the power transmission member 50 that functions as the sun gear of the side planetary gear mechanism 70 cannot be rotated (revolved). ing. Therefore, the side planetary gear mechanism 70 constitutes a star-type gear mechanism with fixed arms.

  Next, the operation of the driving device 1 according to this embodiment will be described. In the driving device 1, the side carrier 74 is supported so as not to rotate relative to the support shaft 17, so that the side planetary gear mechanism 70 is always a star shape. In the driving device 1, a load (rotational load) necessary for rotating the cylinder body 10 with respect to the support shaft 17 by mounting an article on the cylinder body 10 of the main body side roller 2 is the side roller 3. When the rotational load of the three cylindrical bodies 71, 71 is larger, the main body side planetary gear mechanisms 12, 12 are of a planetary type.

  More specifically, the side planetary gear mechanism 70 has an arm of the planetary gear 77 as shown by a broken line in FIG. 3 even when the cylinder 71 of the side roller 3 is freely rotatable. Is in a fixed state. In this state, when an external force is applied to the main body side roller 2 so as to prevent the cylinder 10 from rotating, the main body side planetary gear mechanism 12 provided on the main body side roller 2 side as shown by a broken line in FIG. The 12 internal gears 41 are fixed. Here, the rotating shaft 27 and the planetary gear 40 constituting the sun gear of the main body side planetary gear mechanisms 12 and 12 are in a freely rotatable state. Therefore, in a state in which the cylindrical body 71 of the side roller 3 is freely rotatable, the main body side planetary gear mechanisms 12 and 12 constitute a planetary planetary gear mechanism as shown by a solid line in FIG. Therefore, when the motor 11 operates in this state, the output of the motor 11 is transmitted from the rotating shaft 27 to the side planetary gear mechanism 70 via the main body side planetary gear 40 and the power transmission member 50.

  That is, when the rotational load acting on the main body side roller 2 is larger than the rotational load acting on the side rollers 3 and 3 as described above, a power transmission member corresponding to the sun gear of the side planetary gear mechanism 70. 50 rotates, and the power of the motor 11 is transmitted to the internal gear 78 fixed to the inner peripheral surface of the cylindrical body 71 via the planetary gear 77. Here, as described above, the side planetary gear mechanism 70 is always a star type, and when the side rollers 3 and 3 are rotated, the main body side planetary gear mechanisms 12 and 12 are planetary types. Therefore, the side roller 3 rotates in the direction opposite to the rotation direction of the rotation shaft 27 of the motor 11.

  On the other hand, when the rotational load for rotating the cylindrical body 10 of the main body side roller 2 is smaller than the rotational load of the cylindrical bodies 71, 71 of the side rollers 3, 3, the main body as shown by a broken line in FIG. The power transmission member 50 that functions as the arms of the side planetary gear mechanisms 12 and 12 becomes substantially unrotatable. Thereby, as shown by a solid line in FIG. 4, the main body side planetary gear mechanisms 12, 12 have a star shape. Thereby, the torque of the motor 11 is transmitted from the rotating shaft 27 to the internal gear 41 via the planetary gear 40, and the cylinder 10 of the main body side roller 2 rotates in the direction opposite to the rotating direction of the motor 11.

  As described above, the driving device 1 of the present embodiment can provide a power source for rotating the main body side roller 2 and a power source for rotating the side rollers 3 and 3 with a single motor 11. it can. Therefore, the drive device 1 has a compact device configuration and a low manufacturing cost.

  The drive device 1 can smoothly switch the power transmission system that transmits the power of the motor 11 according to the magnitude of the rotational load acting on the main body side roller 2 and the side side rollers 3 and 3. Therefore, the driving device 1 can operate the main body side roller 2 and the side side rollers 3 and 3 over a desired time.

  In the above embodiment, the shaft center of the main body side roller 2 and the side side rollers 3 and 3 coincides with the shaft center position of the support shaft 17, but the present invention is not limited to this. The side roller 2 and the side rollers 3 and 3 may be eccentrically rotated with respect to the support shaft 17.

  Moreover, in the said embodiment, although the cylinders 10 and 71 of the main body side roller 2 and the side side rollers 3 and 3 were cylindrical, this invention is not limited to this, For example, cross-sectional shape is an ellipse. You may be comprised by the shape and the polygonal cylinder.

  The motor 11 employed in the above embodiment is a so-called outer rotor type motor in which the rotor 21 rotates around the stator 20 attached to the support shaft 17. However, the present invention is not limited to this, and a motor in which a rotor arranged at the center portion of the stator rotates may be adopted.

  In the above embodiment, the driving device 1 has a configuration in which the side rollers 3 and 3 are arranged at positions adjacent to both ends of the main body side roller 2, but only at a position adjacent to one of the end portions. It is good also as a structure in which the side roller 3 was provided.

  Next, an embodiment of a transfer apparatus and a transport system configured by adopting the drive device 1 described above will be described in detail with reference to the drawings. In the following description, unless otherwise specified, the vertical positional relationship is based on a normal installation state as illustrated.

  As shown in FIGS. 5 and 7, the transport system 100 includes a main transport line 101, a transport path that includes a slave transport line 102 that transports the article W to be transported above the main transport line 101, and a main transport line 101. And a transfer device 103 that moves the article to be transported W between the secondary transport line 102 and the secondary transport line 102.

The cylindrical body 113 is closed at both ends by closing members 117 and 118. Fixed shafts 120 and 121 protrude from both ends of the cylindrical body 113. The cylindrical body 113 is supported so as to be rotatable relative to the fixed shafts 120 and 121 via bearings 122 and 123 mounted inside the closing members 117 and 118.

  The motor 115 and the speed reducer 116 are unitized as shown in FIG. 6 and are housed inside the cylinder 113 as the drive unit 124. The motor 115 is a brushless motor in which a plurality of stators 126 made of electromagnets, a rotor 127 having magnetic poles, and a position detector (not shown) are built in an inner cylindrical member 125. The stator 126 is a coil in which a conductive wire is wound around an iron core, and is integrally attached to the inner cylinder member 125. On the other hand, the rotor 127 is housed inside the inner cylinder member 125, and the axis coincides with the axis of the inner cylinder member 125. The rotor 127 is rotatably supported with respect to the fixed shaft 121 via the bearing 130. The other end of the rotor 127 is connected to the speed reducer 116 via a bearing 131. The position detector is configured by a Hall IC or the like in which all or part of the Hall element and the power switching circuit are integrated, and detects the magnetic pole position of the rotor 127.

  The speed reducer 116 is constituted by a triple planetary gear train, and reduces the rotational speed of the rotor 127 of the motor 115 at a predetermined reduction ratio and outputs it to the output shaft 132. In this embodiment, the speed reducer 116 has the above-described configuration. However, the present invention is not limited to this, and any type may be used as long as it has a mechanism that can reduce the rotational power of the motor 115. There may be.

  The output shaft 132 of the speed reducer 116 is connected to the closing member 117 via the connecting member 133. Therefore, the torque of the motor 115 is decelerated by the speed reducer 116 and transmitted to the closing member 117 via the connecting member 133. Since the closing member 117 is integrated with the cylinder 113, the cylinder 113 receives the torque transmitted to the closing member 117 and rotates around the fixed shafts 120 and 121.

  The free roller 111 has a configuration in which the drive unit 124 including the motor 115 and the speed reducer 116 is removed from the above-described motor built-in roller 110. That is, the free roller 111 is a roller that does not have a built-in power source in which the opening portions at both ends of the hollow cylinder 113 are closed by the closing members 117 and 118 having the fixed shafts 120 and 121 attached thereto via the bearings 122 and 123. In other words, the cylindrical body 113 is freely rotatable with respect to the fixed shafts 120 and 121.

  As shown in FIG. 5 and FIG. 7, the main transport line 101 hangs a belt 135 across the motor-incorporated roller 110 and one or a plurality of free rollers 111, and the rotational force of the motor-incorporated roller 110 is free roller It is configured to propagate to the 111 side. The main transport line 101 is divided into an upstream main transport line 101a and a downstream main transport line 101b by a branching portion 141 provided in the middle of the transport path. The branching portion 141 is a part for branching the article W to be transported flowing on the upstream main transport line 101a to the downstream main transport line 101b or the secondary transport line 102, and the transfer device 103 is arranged.

  The transfer device 103 is a device in which the transfer device 150 is mounted on the main body frame 140 so as to be movable up and down. The main body frame 140 is a frame configured by attaching beams 143 to the upper end side and the lower end side of the four columns 142, and functions as a guide for the transfer device 150.

  The transfer device 150 is configured such that two drive devices 1 described above are attached in parallel to two side frames 151 and 151 arranged in parallel, and two free rollers 111 are arranged therebetween. It is what is done. The transfer device 150 can prevent the side frames 151 and 151 from rotating the side rollers 3 and 3 of the driving device 1 and the rotation of the main body side roller 2. And a main body brake (not shown). As the main body brake and the side brake, conventionally known ones such as a belt brake and a disc brake can be employed. Further, the side brake is provided with an opening portion that opens outward in the closing members 73 and 73 of the side rollers 3 and 3, and a pin or the like is inserted into the opening portion to prevent rotation. Any configuration may be adopted as long as it can prevent the rotation of the side rollers 3 and 3 such as a configuration in which a wedge-shaped member can be inserted into the outer peripheral portion of the side rollers 3 and 3.

  One end of belts 152, 152 is attached to the side rollers 3, 3 of the driving device 1 constituting the transfer device 150. The other end side of the belt 152 is fixed to a beam 143 attached to the upper end side of the main body frame 140. The belt 152 is fixed so as to extend vertically in the vertical direction with respect to the main body frame 140. That is, the transfer device 150 has the structure in which the side rollers 3 of the drive device 1 are arranged at the four corners and is suspended from the upper end side of the main body frame 140 by the belt 152 attached to the side rollers 3. It has become. Therefore, the transfer device 150 can be raised to the upper end side of the main body frame 140 by rotating the side roller 3 in a predetermined direction and winding the belt 152, and by rotating in the reverse direction, the transfer of the main body frame 140 can be performed. It can be lowered to the lower end side.

  The secondary transport line 102 is arranged directly above the downstream main transport path 101b so as to be parallel to the downstream main transport path 101b. Similar to the main transport line 101, the secondary transport line 102 is configured by installing a motor built-in roller 110 and a free roller 111 at predetermined intervals between two side frames 112, 112 arranged in parallel. The secondary conveyance line 102 is arranged at a position where the conveyance surface is flush with the conveyance surface of the transfer device 150 when the transfer device 150 is raised to the upper end side of the main body frame 140.

  Subsequently, the operation of the transport system 100 of the present embodiment will be described in detail with reference to the drawings. When the article to be transported W is mounted on the upstream main transport line 101a as shown in FIG. 7, electric power is supplied to the motor built-in roller 110 constituting the upstream main transport line 101a based on control by a control device (not shown). The When electric power is supplied to the motor built-in roller 110, the motor built-in roller 110 starts rotating. In conjunction with this, the power of the motor built-in roller 110 is transmitted to the free roller 111 via the belt 135, and the free roller 111 also starts rotating. Thereby, the to-be-conveyed object W mounted on the main conveyance line 101 is conveyed toward the downstream side.

  When the article to be transported W that has flowed on the upstream main transport line 101a approaches the branching section 141 as described above, the control means performs a lateral brake (see FIG. 5) of the transfer device 150 disposed in the branching section 141. After applying a braking force to the side rollers 3 and 3 of the drive device 1 by a not-shown), the drive device 1 is energized.

  Here, in a state in which the side brake is operated with respect to the driving device 1, the rotational load of the cylindrical body 71 of the side rollers 3 and 3 is larger than the rotational load of the cylindrical body 10 of the main body side roller 2. The side planetary gear mechanisms 70 and 70 in the side rollers 3 and 3 are locked. Therefore, when a braking force is applied to the side rollers 3 and 3, the power transmission member 50 that functions as an arm of the main planetary gear mechanism 12 is fixed, and the side planetary gear mechanism is fixed. 70 and 70 are star-shaped. Accordingly, when the motor 11 is energized in this state, the power of the motor 11 is transmitted to the internal gear 41 and the main body side roller 2 starts to rotate. When the main body side roller 2 starts to rotate, the article W to be transported that has flowed on the upstream main transport line 101a is drawn into the branch portion 141.

  The control means is configured to transfer the transported object that has arrived at the branching part 141 before the transported object W that has flowed on the main transporting line 101 reaches the branching part 141 or when the transported object W141 reaches the branching part 141. It is confirmed whether the article W should be transported to the downstream main transport line 101b or to the slave transport line 102 positioned above.

  Here, when the transported object W present in the branching portion 141 is allowed to flow as it is to the downstream main transport line 101b, the control unit keeps the side brake of the transfer device 150 operated, thereby driving the driving device 1. As a result, the article to be conveyed W is moved, and energization to the motor built-in roller 110 arranged in the downstream main conveyance line 101b is started. Thereby, the to-be-conveyed object W which flowed from the upstream main conveyance line 101a passes the branch part 141, and is withdrawn to the downstream main conveyance line 101b.

  On the other hand, when the transferred object W that has reached the branching portion 141 is paid out to the secondary transfer line 102, the control device causes a lateral brake of the transfer device 150 when the transferred object W is mounted on the transfer device 150. Is released. When the braking force acting on the side rollers 3 and 3 is released, the side rollers 3 and 3 can be freely rotated, and the power transmission mechanism in the driving device 1 is switched. More specifically, in this state, the side rollers 3 and 3 can freely rotate, while the main body side roller 2 is subjected to a rotational load due to the weight of the conveyed object W that has arrived at the branch portion 141. ing. That is, when the lateral brake is released in a state where the conveyed object W has arrived at the branching portion 141, the rotational load of the main body side roller 2 becomes larger than the rotational load of the side side rollers 3 and 3.

  Here, as described above, in the driving device 1, the main body side planetary gear mechanism 12 is of a planetary type on condition that the rotation load of the main body side roller 2 is larger than the rotation load of the side rollers 3 and 3. . Therefore, when the control means releases the side brake of the transfer device 150, the power of the motor 11 is transmitted to the side rollers 3 and 3.

  When power is transmitted to the side rollers 3 and 3, the belt 152 attached to the outer periphery of the side rollers 3 and 3 is wound around the cylindrical body 71. Thereby, the transfer device 150 climbs upward along the main body frame 140.

  When the transfer device 150 reaches the upper end of the main body frame 140, the control means activates a lateral brake of the transfer device 150. Thereby, the power transmission mechanism of the drive device 1 is switched again, and the main body side roller 2 starts to rotate. That is, when the lateral brake of the transfer device 150 is operated, the rotational load of the side rollers 3 and 3 becomes larger than the rotational load of the main body side roller 2, and the main body side planetary gear mechanism 12 of the driving device 1 is It changes to a type | mold and the main body side roller 2 starts rotation.

  When the main body side roller 2 starts to rotate, the control means also starts energization to the motor built-in roller 110 of the secondary conveyance line 102. As a result, the article to be transported W existing in the branching section 141 is paid out from the branching section 141 to the secondary transport line 102.

  When the payout of the transported object W is completed, the control means operates the main body brake of the transfer device 150. When the brake for the main body is operated, the rotational load of the main body side roller 2 becomes larger than the rotational load of the side side roller 3, and the main body side planetary gear mechanism 12 becomes a planetary type.

  The control means reverses the motor 11 at the same time as operating the main body brake. Thereby, the torque of the motor 11 is transmitted to the cylindrical body 10 of the main body side roller 2 via the rotary shaft 27, the planetary gear 40 and the internal gear 41, and the cylindrical body 10 is rotated in the rotational direction when the transfer device 150 is raised. On the other hand, it starts to rotate in the opposite direction.

  When the cylinder 10 of the side rollers 3 and 3 is reversed as described above, the belt 152 wound around the outer periphery of the cylinder 10 is unwound. As a result, the transfer device 150 gradually descends and eventually returns to the height of the main transport line 101. When the transfer device 150 returns to the height of the main transport line 101, the control unit stops energizing the motor 11 and waits for the next transported object W to arrive at the branching unit 141.

  As described above, the transport system 100 according to the present embodiment employs the transfer device 150 configured using the driving device 1 illustrated in the above embodiment, and transports the article W to be transported by the main body side roller 2. In addition, the transfer device 150 is moved up and down by the side rollers 3 and 3. In other words, in the transport system 100, the transfer device 150 is configured to cover the drive source for transporting the article W to be transported and the drive source for raising and lowering by the drive device 1. Therefore, the transport system 100 and the transfer device 150 have a very simple device configuration.

  In this embodiment, the main transport line 101, the secondary transport line 102, and the transfer device 150 are roller conveyors each including a plurality of motor-equipped rollers 110 and the drive device 1 as drive sources and these free rollers 111. However, the present invention is not limited to this, and may be a belt conveyor using the motor built-in roller 110 or the driving device 1 as a driving source.

  Further, in the above embodiment, the transfer device 150 is configured such that the two drive devices 1 are arranged so that the side rollers 3 are at the four corners, and the belt 152 is attached to each of them. It is not limited to. More specifically, for example, as shown in FIG. 8, the driving device 1 is arranged on one end side of the transfer device 150, and the side rollers 3 and 3 of the driving device 1 and the other end side of the transfer device 150 are arranged. A belt 152 may be attached to the arranged free rollers 111, and the belt 152 may be suspended on a pulley 153 installed on the upper end side of the main body frame 140. According to such a configuration, the transfer device 150 can be operated by the single drive device 1, and the device configuration of the transport system 100 can be further simplified.

  In the above embodiment, the amount of winding of the belt 152 attached to the side rollers 3 and 3 is adjusted by rotating the side rollers 3 and 3, and the height of the transfer device 150 is adjusted. However, the present invention is not limited to this. More specifically, for example, as shown in FIG. 9, an external gear 155 is attached to the outer periphery of the side rollers 3 and 3, and a rack 156a (guide member) and a pinion 156b (tooth member) are attached to the external gear 155. It is good also as a structure which couple | bonded the raising / lowering mechanism 156 comprised from the raising / lowering mechanism 156 comprised, and the sprocket 157a (tooth member) and the chain 157b (guide member). Even in such a configuration, the transfer device 150 can be raised and lowered smoothly using the torque of the side rollers 3 and 3.

  Further, as described above, in the case of providing a guide structure constituted by the combination of the rack 156a and the pinion 156b or the combination of the sprocket 157a and the chain 157b, there is a conveyance path configured to move the transfer device 150 on a predetermined horizontal plane. Even in the case where it is constructed, even if the transport path in which the transfer device 150 moves in the vertical direction or moves along the inclined surface is constructed as shown in FIG. A transfer system that can be transferred can be provided.

  As described above, in the transport system 100, the main body brake for braking the main body side roller 2 of the driving device 1 and the side brake for braking the side rollers 3, 3 are provided. A mechanical brake, an electromagnetic brake, or the like can be used for the brake for the side and the brake for the side.

  Further, when the transfer apparatus 150 is configured to move up and down like the above-described transfer system 100, acceleration at the time of lowering due to the weight of the transfer apparatus 150 and the weight of the object W to be transferred mounted thereon is performed. In order to reduce this, it is desirable to have a configuration provided with a counter balancer or the like. According to such a configuration, the vertical movement of the transfer device 150 can be made even smoother and more stable.

  Moreover, although the conveyance system 100 was the structure which raises / lowers the transfer apparatus 150 using rotation of the side side rollers 3 and 3, this invention is not limited to this, The main body side roller 2 of It is good also as a structure which raises / lowers the transfer apparatus 150 using rotation, and conveys the to-be-conveyed object W using rotation of the side side rollers 3 and 3. FIG.

  Further, in the above-described embodiment, the configuration in which the slave transport line 102 is arranged in parallel above the downstream main transport line 101b is illustrated, but the present invention is not limited to this, and the slave transport line 102 is inclined. It may be arranged with the posture. In addition, the sub-conveying line 102 is configured to convey the article W to be conveyed in the same direction as the downstream main conveying line 101b. However, the sub-conveying line 102 conveys the article W to be conveyed by the downstream main conveying line 101b. It is good also as a structure which conveys the to-be-conveyed object W in the direction which cross | intersects with a direction. Moreover, although the main conveyance line 101 and the subordinate conveyance line 102 which comprise the above-mentioned conveyance system 100 comprised all the linear conveyance paths, they comprise the conveyance path bent in the middle. Also good.

  Further, since the transfer device 150 described above is provided with a main body brake and a side brake for rotation braking of the main body side roller 2 and the side side rollers 3 and 3, the rotation direction of the motor 11 is adjusted. By doing so, the delivery direction of the transported object W by the transfer device 150 can be changed. Therefore, as shown in FIG. 9, a transport line 102 is provided according to the raised position of the transfer device 150, and a slave transport line 158 that transports the transported object W in the opposite direction. , 158 may be selected and the conveyed object W may be paid out.

  The transport system 100 described above has a three-dimensional transport path that vertically moves the transfer device 150 by rotating the side rollers 3 and 3, but the present invention is not limited to this. It may be moved up and down along an inclined surface, or may be configured like a transport system 170 shown in FIG.

  More specifically, the transport system 170 moves horizontally between two transport lines 171 and 172 for transporting articles as shown in FIG. 11, and transfers a transferred object W (transfer apparatus 175). ). The conveyance lines 171 and 172 are configured by a conventionally known conveyance device such as a roller conveyor such as the main conveyance line 101 and the secondary conveyance line 102 or a belt conveyor.

  The transfer device 175 pulls the object to be transferred onto the transfer device 175 or pays out the object to be transferred existing on the transfer device 175 by the power of the driving device 1 attached between the side frames 176 and 176. In addition to the operation, it is configured to be movable along rails 177a and 177b laid in parallel at a predetermined interval on a predetermined plane.

  More specifically, as shown in FIG. 11 and the like, the transfer device 175 has a bulging portion 179 that is bent and bulged in a step shape on one end side, and has a protruding portion 174 on the other end side. The side frames 176 and 176 are arranged in parallel, and the drive device 1 and the driven roller 180 are attached therebetween. More specifically, the side frame 176 includes a parallel portion 178, and a bulging portion 179 and an overhanging portion 174 that are bent stepwise with respect to the parallel portion 178. The bulging portion 179 is continuous with one end side of the parallel portion 178, and is vertically bent with respect to the vertical bulging portion 181a. It is comprised from the horizontal bulging part 181b extended. The overhang portion 174 is a portion that is continuous with the other end side of the parallel portion 178 and is bent perpendicularly thereto. In the side frames 176 and 176, the parallel portions 178 and 178 and the horizontal bulge portions 181 a and 181 a are parallel to each other, and the overhang portion 174 and the bulge portion 179 bulge toward the outside of the transfer device 175. Is arranged.

  As shown in FIG. 10, a moving roller 184 is attached to the overhang portion 174. The moving roller 184 is a wheel that is attached so that the axle protrudes outward in the vertical direction with respect to the overhang portion 174 and is freely rotatable. As shown in FIG. 10, the roller 184 is fitted into the rail 177a, and the moving direction is restricted. The driving device 1 is mounted between the horizontal bulging portions 181a and 181a. Bevel gears 182 and 182 are fixed to the outer peripheral portions of the side rollers 3 and 3 of the driving device 1 so as to be rotatable integrally with the side rollers 3 and 3.

  Further, the rotary shafts 183 and 183 are mounted on the vertical bulging portions 180b and 180b of the side frames 176 and 176 so as to protrude toward the driving device 1 side. Bevel gears 185 and 185 are attached to the front end portions of the rotating shafts 183 and 183, that is, on the driving device 1 side so as not to rotate relative to the rotating shafts 183 and 183. The bevel gears 185 and 185 mesh with the bevel gears 182 and 182 mounted on the side rollers 3 and 3 of the driving device 1, respectively. Therefore, when the side rollers 3 and 3 rotate, this torque is transmitted to the rotary shafts 183 and 183 via the bevel gears 182 and 185.

  Moving rollers 186 and 186 are attached to portions of the rotary shafts 183 and 183 on the vertical bulging portions 180 and 180 side so that they cannot rotate relative to the rotary shafts 183 and 183. The moving rollers 186 and 186 are fitted in the rails 177b described above. Therefore, when torque is transmitted to the rotating shafts 183 and 183 as the side rollers 3 and 3 are rotated, the moving rollers 186 and 186 are rotated together with the rotating shafts 183 and 183, and the transfer device 175 is translated in the lateral direction. Can be made.

  A mechanical or electromagnetic brake (not shown) capable of applying a braking force to the moving rollers 186 and 186 as necessary is provided in the vicinity of the moving rollers 186 and 186. Therefore, the transfer device 175 can apply a rotational load (braking force) to the side rollers 3 and 3 by applying this brake.

  As shown in FIG. 10, the driven roller 180 is disposed between the parallel portions 178 and 178 of the side frames 176 and 176. The driven rollers 180 and 180 are rotatable relative to a support shaft 190 supported by bearings 188 and 188 disposed at both ends of a hollow cylindrical cylinder 187.

  The driven roller 180 includes a rotation amount adjusting mechanism 191 inside the cylindrical body 187. The rotation amount adjusting mechanism 191 is roughly composed of a nut 192 (cylinder side member), a cylindrical screw 193 (moving member), and stoppers 195a and 195b (blocking members). The nut 192 has an outer shape that is substantially the same as the outer shape of the cylindrical body 187, and a screw that can be screwed with a cylindrical screw 193 is formed on the inner peripheral surface thereof. The nut 192 is fixed to a substantially central portion of the cylindrical body 187 in the axial direction.

  The cylindrical screw 193 is a member having a through-hole 193a in the center and a screw that can be screwed with a screw formed inside the nut 192 on the outer periphery. The cylindrical screw 193 is attached to the nut 192 in a state where the support shaft 190 is inserted into the through hole 193a. Further, the rotation of the cylindrical screw 193 is restricted by the needle 200 disposed along the support shaft 190. Therefore, the cylindrical screw 193 slides along the support shaft 188 when the cylindrical body 187 rotates. More specifically, the cylindrical screw 193 advances in the direction of arrow a (right side in FIG. 11) when the driven roller 180 rotates in a direction indicated by an arrow A in FIG. 11 (hereinafter referred to as a positive direction as necessary) When rotating in the direction indicated by the arrow B (hereinafter referred to as the reverse direction if necessary), the process proceeds in the direction of the arrow b (left side in FIG. 11).

  When the cylindrical body 187 advances until the cylindrical screw 193 comes into contact with the right stopper 195b, the cylindrical body 187 can no longer rotate in the direction of arrow A (the direction in which the article W is pulled toward the transfer device 175). Conversely, when the cylindrical body 187 advances until the cylindrical screw 193 hits the left stopper 195a, the cylindrical body 187 can no longer rotate in the direction of arrow B (the direction of paying out the article W to be transferred from the transfer device 175).

  The stoppers 195a and 195b are for preventing the cylindrical screw 193 from moving in the axial direction of the support shaft 188. Each of the stoppers 195a and 195b has a predetermined interval at a position adjacent to the cylindrical screw 193 in the extending direction of the support shaft 188. Is fixed so that it cannot move relative to the support shaft 188. The stoppers 195a and 195b are configured such that the fixing position with respect to the support shaft 188 can be appropriately adjusted from the opening (not shown) of the cylindrical body 187. Therefore, the cylindrical screw 193 can slide in the region sandwiched between the stoppers 195a and 195b. Accordingly, the cylindrical body 187 can slide freely until the end of the cylindrical screw 193 hits one of the stoppers 195a and 195b as it rotates. No more sliding.

  Two belts 196 and 196 are suspended between the driven roller 180 and the main body side roller 2 of the driving device 1. The belts 196 and 196 function as a power transmission member that transmits power between the driven roller 180 and the main body roller 2, and the conveyance object W between the transfer lines 171 and 172 and the transfer device 175. A transfer surface for delivery is configured.

  As shown in FIG. 11, the rails 177a and 177b extend in a direction substantially orthogonal to the conveyance direction of the article W to be conveyed by the conveyance lines 171 and 172, respectively. The rails 177a and 177b are fitted with the moving rollers 184 and 184 and the moving rollers 186 and 186 of the transfer device 175, and the transfer device 175 is transported in the horizontal direction, that is, the transported object W is transported by the transport lines 171 and 172. It guides in a direction that intersects the direction. The rails 177a and 177b are provided with roller stoppers 197a and 197b and roller stoppers 198a and 198b. The roller stoppers 197a and 197b and the roller stoppers 198a and 198b are positions where the moving roller 186 strikes when the transfer device 175 arrives at a position adjacent to the conveying lines 171 and 172 as shown by a solid line or a two-dotted line in FIG. Is provided. Therefore, the transfer device 175 can travel in a straight line between the region adjacent to the downstream end of the transport line 171 and the position adjacent to the upstream end of the transport line 172.

  The transfer system 170 pulls the transfer object W conveyed by the transfer line 171 to the transfer device 175 as indicated by an arrow in FIG. 10, and then horizontally moves the transfer device 175 to the transfer line 172 side, The operation of paying out the conveyed product W to the conveying line 172 side is performed. Hereinafter, the operation of the transport system 170 will be described in detail. As described above, the driving device 1 has a relationship in which the rotation direction of the rotation shaft 27 of the motor 11 and the rotation direction of the main body side roller 2 and the side roller 3 are reversed. For convenience, when the braking force is applied to the side roller 3, the main body side roller 2 rotates in the direction indicated by the arrow A in FIG. 11 and the like, and when the braking force is applied to the main body side roller 2, the arrow B indicates The state in which the side roller 3 rotates in the direction is defined as normal rotation, and the energized state of the motor 11 at that time is defined as the positive direction. On the other hand, when the braking force is applied to the side roller 3, the main body side roller 2 rotates in the direction indicated by the arrow B in FIG. 12, and when the braking force is applied to the main body side roller 2, the arrow A indicates. The state in which the side roller 3 rotates in the direction is defined as reverse rotation, and the energized state of the motor 11 at that time is defined as the reverse direction.

  In the transport system 170, as shown by a solid line in FIG. 12, in the initial state, the transfer device 175 is arranged at a position adjacent to the downstream end of the transport line 171, and the transported object W is paid out from the transport line 171. waiting.

  Here, when the transfer device 175 is stopped at a position adjacent to the conveyance line 171 and before the main body side roller 2 starts to rotate (hereinafter referred to as a mounting standby state if necessary), FIG. As shown by a solid line, the cylindrical screw 193 in the driven roller 180 is in contact with the left stopper 195a. When the driven roller 180 rotates in the forward direction (direction of arrow A in FIG. 12) as described above, the cylindrical screw 193 advances to the right side (in the direction of arrow a in FIG. 12) and reverse (in the direction of arrow B in FIG. 12). Rotate to the left (arrow b direction in FIG. 12). Therefore, in the mounting standby state, the driven roller 180 and the main body side roller 2 connected to the driven roller 180 via the belt 196 can be freely rotated in the forward direction (arrow A direction).

  When it is detected that the article W has reached the downstream end of the transfer line 171 while the transfer device 175 is in the transfer standby state, the control means of the transfer system 170 controls the motor 11 of the drive device 1 to be correct. Start energizing in the direction. At the same time, the control means applies a braking force that does not exceed the torque of the motor 11 by applying a brake installed in the vicinity of the moving rollers 186 and 186. More specifically, in the control means, the rotational load Fs applied to each of the side rollers 3 and 3 of the driving device 1 is larger than the rotational load Fm acting on the main body side roller 2, and the rotational load Fs is increased. The brake is applied to the extent that the torque of the motor 11 is not exceeded.

  As described above, when the motor 11 is energized in the forward direction and the brake is applied, the driving device 1 is in a state in which the side planetary gear mechanism 70 is fixed, and the main body planetary gear mechanism 12 is The main body side roller 2 begins to rotate. Thereby, the belt 196 suspended over the main body side roller 2 and the driven roller 180 starts to move in the direction indicated by the arrow Y1 in FIG. 12, and the conveyed object W starts to move toward the transfer device 175.

  Here, the interval between the stoppers 195a and 195b is adjusted in advance according to the operating time and operating distance of the belt 196 required to transfer the transported object W to the transfer device 175. Therefore, when the main body side roller 2 of the driving device 1 is rotated forward until the cylindrical screw 193 comes into contact with the stopper 195b, the article W to be conveyed discharged from the conveying line 171 is drawn onto the transfer device 175.

  When the cylindrical screw 193 comes into contact with the stopper 195b, the driven roller 180 cannot rotate in the forward direction. As a result, a large braking force acts on the main body side roller 2 of the driving device 1 connected via the belt 196, and the rotational load Fs acting on each of the side rollers 3 and 3 of the driving device 1 becomes the main body side. The rotational load Fm acting on the roller 2 becomes larger.

  When the rotational load Fm acting on the main body side roller 2 becomes larger than the rotational load Fs acting on the side rollers 3 and 3, the main body side planetary gear mechanism 12 becomes a planetary type, and the side planetary gear mechanism 70 becomes a star type. It becomes. For this reason, when the transfer of the article W to be transferred to the transfer device 175 is completed, the main body side roller 2 stops and the side rollers 3 and 3 start to rotate. When the control means detects that the side rollers 3 and 3 have started rotating, it releases the brake for the moving roller 186. Along with this, the transfer device 175 starts to move toward the transfer line 172 side (left side in FIG. 12) as indicated by an arrow X1 in FIG.

  When the transfer device 175 moves until the moving rollers 184 and 186 abut against the roller stoppers 197a and 198a installed on the rails 177a and 177b, the control means once energizes the motor 12 of the drive device 1 in the positive direction. At the same time, the brake for the moving roller 186 is operated, and a braking force that does not exceed the torque of the motor 11 is applied to the moving rollers 186 and 186. As a result, the transfer device 175 stops at a position adjacent to the left conveyance line 172.

  Here, when the transfer device 175 is stopped at a position adjacent to the conveyance line 172 and before the main body side roller 2 starts to rotate (hereinafter referred to as a payout waiting state if necessary), FIG. As shown, the cylindrical screw 193 in the driven roller 180 is in contact with the right stopper 195b. Therefore, in the payout waiting state, the driven roller 180 and the main body side roller 2 connected thereto via the belt 196 can freely rotate in the reverse direction (the direction of arrow B in FIG. 13). .

  When the transfer device 175 enters the payout standby state, the control unit starts energization in the reverse direction to the motor 12 of the drive device 1. Here, as described above, since the rotation load Fs (Fs> Fm) larger than the rotation load Fm acting on the main body side roller 2 is acting on the side rollers 3 and 3, the side planetary gears. 70 becomes a fixed state, and the main body side planetary gear mechanism 12 becomes a star shape. As a result, the main body side roller 2 and the driven side roller 180 connected thereto via the belt 196 start to rotate in the reverse direction, and the belt 196 starts to move in the direction indicated by the arrow X2 in FIG. The object W starts to move to the transfer device 175 side.

  When the delivery of the transported object W to the transport line 172 is started, the driven roller 180 rotates in the forward direction. As a result, the cylindrical screw 193 accommodated in the driven roller 180 starts to move toward the stopper 195a, and the left end of the cylindrical screw 193 hits the stopper 195a when the discharge of the conveyed object W is completed, and the driven roller 180 Becomes impossible to rotate in the reverse direction (the direction of arrow B in FIG. 12). Accordingly, a large braking force acts on the main body side roller 2 of the driving device 1, and the rotational load Fm acting on the main body side roller 2 of the driving device 1 is larger than the rotational load Fs acting on the side side rollers 3 and 3. Become. (Fm> Fs)

  As described above, when the rotational load Fm becomes larger than the rotational load Fs, the main body side planetary gear mechanism 12 of the driving device 1 becomes a planetary type, and the side planetary gear mechanism 70 becomes a star type. For this reason, when the delivery of the article W to be conveyed to the conveyance line 172 is completed, the side rollers 3 and 3 start to rotate in the reverse direction instead of the main body roller 2. When the control means detects the start of rotation of the side rollers 3 and 3, it releases the brake for the moving roller 186. As a result, the power of the driving device 1 is transmitted to the moving roller 186 via the side rollers 3 and 3 and the bevel gears 182 and 185, and the transfer device 175 moves to the conveying line 171 side (shown by an arrow X2 in FIG. In FIG. 13, it starts to move horizontally (to the right).

  When the transfer device 175 moves horizontally to the right and the moving rollers 184 and 186 come into contact with the roller stoppers 197a and 198a installed on the rails 177a and 177b, the control unit stops energizing the motor 12. Then, the brake for the moving roller 186 is operated. Thereby, the transfer device 175 returns to the mounting standby state, and a series of transfer operations of the transported object W is completed.

  The transfer device 175 employed in the above-described transfer system 170 serves as a drive source for transferring the object W to be transferred only by the drive device 1 and a drive source for moving the transfer device 175. Can do. Therefore, the transport system 170 has a very simple device configuration.

  As described above, the transfer device 175 adjusts the distance between the stoppers 195a and 195b constituting the rotation amount adjusting mechanism 191 and the cylindrical screw 193, that is, the distance between the stoppers 195a and 195b, thereby allowing the main body side roller 2 and the driven device to move. The rotation limit of the roller 180 can be adjusted. Therefore, the transfer device 175 adjusts the distance between the stoppers 195a and 195b in accordance with the distance between the transfer device 175 and the ends of the transfer lines 171 and 172, so that the object to be transferred W can be provided without providing a sensor or the like. Can be moved accurately.

  Further, when the main body side roller 2 and the driven roller 180 rotate by a predetermined amount and the cylindrical screw 193 comes into contact with the stopper 195a and the stopper 195b and the movement is prevented and prevented, the transfer device 175 The driven roller 180 can no longer rotate, and a large rotational load acts on the cylinder 10 of the main body side roller 2. Therefore, the transfer device 175 switches the power transmission system in the drive device 1 when the main body side roller 2 and the driven roller 180 are rotated by a predetermined amount, and the transfer of the transported object W is completed. The move starts. Therefore, the transfer device 175 according to the present embodiment can smoothly perform the transfer operation of the transported object W and the movement between the transport lines 171 and 172.

  The transfer device 175 includes rotation direction conversion means 199 configured by a bevel gear 185 mounted on the side rollers 3 and 3 and a bevel gear 182 mounted on the side frame 176 and a movable roller 186. The conveyed object W can be linearly moved between the conveying lines 171 and 172 arranged in parallel. Therefore, the transfer system 170 has a small installation space.

  In the above-described embodiment, an example in which the main body side roller 2 is used as a drive source for moving the article W to be conveyed and the side roller 3 is used as a drive source for moving the transfer device 175 is illustrated. The present invention is not limited to this, and these roles may be reversed.
