Each protruding plate 116 is formed with a concave portion 117 that is detachably engaged with a part of the outer peripheral surface of the operating body 32 and holds the operating body 32 from above and below.

  Then, the operation body 32 is fixed to the right frame body 11 by the two fixing operation means 101 as described above, so that the driving body 31 is maintained in a desired first state.

  In order to release the fixing by the fixing operation means 101, the operator picks the knob 113 and moves the rotating operation body 111 with respect to the moving body 102 in a predetermined direction around the shaft 112 (in FIG. 9, the arrow The rotating operation body 111 is moved in a direction away from the operation body 32 together with the moving body 102. That is, the operator can release the holding of the operating body 32 by the holding portion 114 of the rotating operation body 111 by performing a pulling operation while rotating the rotating operation body 111 a little.

  When the fixing by the fixing operation means 101 is released in this way, the operating body 32 moves downward about the rotation center axis X due to the weight of the driving body 31 and the operating body 32 as shown by a two-dot chain line in FIG. To change its posture from a horizontal posture to an inclined posture. As a result, the driving body 31 is changed from the first state to the second state, and the belt 51 is separated from the conveying roller 23 and is in a non-contact state. At this time, the operator prevents the operating body 32 from falling and rotating by its own weight, for example, by gripping the grip portion 91 of the operating body 32.

  In addition, a stopper means 120 is provided between the right frame body 11 and the operation body 32 to restrict the downward rotation of the operation body 32 and maintain the operation body 32 in an inclined posture. The stopper means 120 has, for example, one end portion attached to the lower horizontal plate portion 14 of the frame body 11 via the attachment ring 121 and the other end portion located in the center in the longitudinal direction of the grip portion 91 of the operating body 32 via the attachment ring 122.

Further, the tilt angle α with respect to the horizontal direction when the operating body 32 is tilted is approximately 15 degrees, for example.

  When the drive body 31 is returned from the second state to the first state, the operator rotates the operation body 32 upward about the rotation center axis X so as to lift the operation body 32, and then performs the rotation operation. It is only necessary to turn the body 111 a little while pushing the body 111 toward the operation body 32 side.

  Next, the operation of the roller conveyor 1 will be described.

  When the roller conveyor 1 is used as a driving conveyor, the operating body 32 is set in a horizontal posture and the driving body 31 is set to the first state.

  When electric power is supplied from the battery means 4 to the electric motor 36 of the driving body 31, the electric motor 36 is actuated to rotate the belt 51, and the belt 51 forcibly causes the roller portion 25 of the conveying roller 23 to rotate. Driven by rotation. As a result, the article W is transported in the transport direction by the roller portion 25 of the transport roller 23.

  Here, for example, when the power supply to the electric motor 36 of the driving body 31 becomes impossible due to the occurrence of a power failure or the battery exhaustion, that is, when the power source is lost, the electric motor 36 becomes inoperable and the roller conveyor 1 cannot be used as a drive conveyor.

  Even in such a case, the roller conveyor 1 can be used as a free conveyor.

  In this case, the operator who is the user releases the fixing of the operating body 32 with respect to the frame body 11 by operating the fixing operation means 101, and then drives the operating body 32 by rotating the operating body 32 downward to the inclined posture. The body 31 is set to the second state.

  In the second state of the driving body 31, the belt 51 is separated from the roller portion 25 of the transport roller 23, so that the roller portion 25 of the transport roller 23 is free to rotate with respect to the support shaft portion 24. Yes.

  For this reason, the article W can be conveyed in the conveyance direction by using the roller portion 25 of the conveyance roller 23 in the free state. Note that the driving body 31 may be set to the second state by removing the operating body 32 together with the driving body 31 from the frame body 11.

  According to the roller conveyor 1, the article W can be conveyed by the conveying means 3 in the driven state when power can be supplied, and the article W can be conveyed by the conveying means 3 in the free state when electric power cannot be supplied. Therefore, one roller conveyor 1 can be used as a driving roller conveyor or a free roller conveyor.

  Further, the drive body 31 can be appropriately switched to the first state for bringing the transport means 3 into the drive state by the upward movement of the operation body 32 with respect to the frame body 11, and is driven by the downward movement of the operation body 32 with respect to the frame body 11. The body 31 can be appropriately switched to the second state for bringing the transport means 3 into the free state.

  Furthermore, by fixing the operating body 32 to the frame body 11 by the fixing operation means 101, the driving body 31 can be appropriately maintained in the first state.

  Further, by gripping the long grip portion 91 of the operation body 32, the state of the drive body 31 can be easily switched manually using the operation body 32.

  Further, since the long grip portion 91 of the operation body 32 is located on the outer side of the frame body 11 in a plan view, the frame body 11 does not get in the way when the grip portion 91 of the operation body 32 is gripped. A person can easily grip the grip portion 91 and has good operability.

  Further, even in any place where there is no commercial power supply, the electric motor 36 is operated based on the power supply from the battery means 4 to bring the conveying roller 23 into a driving state, and the article W is appropriately placed by the conveying roller 23 in this driving state. Can be transported.

  Furthermore, since the drive means 5 can be attached to and detached from the frame means 2, maintenance of the drive means 5 can be facilitated.

  In addition, the drive body 31 has a configuration including the attachment portion 61 and the drive main body portion 62 attached to the attachment portion 61 so that the height position of the drive body 31 can be adjusted. Therefore, by adjusting the height position of the drive main body portion 62, For example, it is possible to easily cope with the vertical dimension of the frame body 11 and the diameter of the transport roller 23.

  Furthermore, it can be used as a drive roller conveyor by, for example, retrofitting the drive means 5 to an existing free roller conveyor. For example, if the free roller conveyor and the driving means 5 are mounted on a truck that performs cargo handling, the driving roller conveyor can be obtained at any place where the unloading operation is performed.

  Further, the length of the drive body 31 can be easily changed and set according to the required drive length, and can easily correspond to the length of the conveyor device.

  The battery means 4 is not limited to, for example, a commercially available portable power source, and may be an on-board battery, a lithium ion battery pack, or the like, and is arbitrary.

  Further, the power source that supplies power to the driving body 31 may be a commercial power source instead of a battery power source, and may be configured to supply power using, for example, a car cigarette socket. Further, for example, a manual power generator You may make it supply the electric power generated by.

  Further, the operation body 32 is not limited to the configuration in which the operation body 32 is rotated in the vertical direction with respect to the frame means 2. In other words, it may be configured such that it can only be detached.

  Further, the conveying means 3 is not limited to the one composed of the conveying roller 23, and may be composed of, for example, an endless conveying belt or a large number of conveying rollers. That is, the conveying device may be a conveyor device other than the roller conveyor.

  Further, the operating body 32 is not limited to one that is operated when the driving body 31 is manually switched between the first state and the second state. For example, when the driving body is manually switched from the second state to the first state. It may be an operating body that is operated only when the driver is operated, or an operating body that is operated only when the drive body is manually switched from the first state to the second state.
