  As shown in the drawings, the movable long object reel is a movable long object reel in which a reel part is provided on a carriage part, and the reel part winds a hose, a cord or other long object. A take-up drum 8 for taking-up and a passive wheel 2 fixed coaxially with the take-up drum 8 on the outer side thereof, and the carriage unit is continuous with the gantry 3 provided with wheels 1 and the gantry 3. The carriage portion is provided with a reel shaft support portion 4 that supports the shaft 7 of the reel portion, and the reel shaft support portion 4 is provided on the reel portion. A rail structure 5 for directly supporting the shaft 7 in a state in which the shaft 7 is stretched and making it movable in the front-rear direction is provided so that the passive wheel 2 and the wheel 1 are within the movable range of the shaft 7. The main configuration is to be able to contact.

  In the movable long reel, the reel unit is configured such that the wheel 1 is provided on the front side of the gantry 3 and the grip arm arm 6 is inclined forward to be supported by the reel shaft support unit 4. The passive wheel 2 is brought into contact with the wheel 1 by moving the shaft 7 forward, so that the rotation of the wheel 1 can be transmitted to the passive wheel 2.

With this configuration, in the movable long reel, the gripping arm rod 6 is tilted forward so that the shaft 7 of the reel portion supported on the rail structure 5 is moved on the rail structure 5. Moving forward, thereby the passive wheel 2 of the reel portion contacts the wheel 1, so that the rotation of the wheel 1 is transmitted to the passive wheel 2. Rotation that is transmitted to the receiving wheel 2 becomes the rotation of the winding drum 8 as it is, to which the set hose, cord and other long object is that is taken either wound on the winding drum 8 by the rotation direction.

  On the other hand, when the gripping arm rod 6 is tilted rearward, the shaft 7 of the reel portion supported on the rail structure 5 moves rearward on the rail structure 5, thereby the reel Since the passive wheel 2 of the part is separated from the wheel 1, the rotation of the wheel 1 is not transmitted to the passive wheel 2. Therefore, regardless of the rotation of the wheel 1, that is, the movement of the carriage, the rotation of the wheel 1 is not transmitted to the reel portion, and the hose, cord and other long lengths set on the winding drum 8 are not transmitted. The object is not taken up by the take-up drum 8 by the movement of the carriage, and is not unwound and pulled out.

Further, when the shaft 7 of the reel portion is moved forward and positioned on the rail structure 5, the wheel 1 can be moved by adjusting the inclination of the grip arm 6 or moving it up and down. It is also possible to increase or decrease the contact pressure of the passive wheel 2, whereby the degree of contact of the passive wheel 2 with the wheel 1 can be controlled. Accordingly, the transmission amount to the receiving wheel 2 rotation of the wheel 1 that could be controlled.

  In other words, the movable long object reel of the present invention is continuously provided by moving the shaft 7 of the reel portion supported on the rail structure 5 freely forward and backward on the rail structure 5. Further, the intermittent transmission state of the passive wheel 2 and the wheel 1 is controlled to control the interlocking of the carriage movement and the reel unit rotation.

  As shown in the above figures, the reel shaft support portion 4 of the movable long reel is fixed to the pedestal portion at two or more points or can be fixed. . That is, as shown in the example of the figure, the frame 3 and the gripping arm rod 6 are fixed at a total of two points, or such a fixing is possible. The present invention is not limited to such a configuration, and includes, for example, a configuration in which the reel unit is supported only on the gantry 3 side or only on the gripping arm rod 6 side. From the viewpoint of the function of the reel shaft support portion 4, it can be said that stronger fixation at a plurality of points is desirable.

Further, examples of smooth movement method of the axis 7 of the reel unit in the rail structure on 5, axis 7 of the reel unit, have to have desired to the rolling or slidable up the rail structure 5.

  FIG. 4 is an explanatory view in a side view showing a state where the forward movement of the reel portion is stopped while the gripping arm rod の of the movable long object reel shown in FIG. 2 is swung forward. is there. That is, the present apparatus is in a movable state with the wheel and the passive wheel being separated. As shown in the figure, the movable long reel can be configured such that the rail structure 5 is provided with a restraining structure 9 that can restrain the movement of the shaft 7 of the reel portion.

In the drawing, the shaft 7 of the reel portion is hooked on a restraining structure 9 forming the hook-like portion, so that the forward movement of the gripping arm rod 6 can be restrained even when the gripping arm rod 6 is tilted forward. .

  Thereby, the shaft 7 of the reel portion does not enter the main line portion of the rail structure 5, and therefore the reel portion does not move forward, so that the state in which the wheel 1 and the passive wheel 2 remain separated is maintained. However, the movable reel for long objects can be moved. Therefore, it is convenient when it is not necessary to wind up or pull out a long object in conjunction with the rotation of the wheel 1 due to movement, or when it is desired to avoid the winding up associated with the movement. Of course, even in this state, manual drawing and winding are possible.

  Although not shown in the drawings, at least one of the wheel 1 and the passive wheel 2 has a configuration in which a concavo-convex structure or a meshing structure is provided on the surface thereof in order to prevent or suppress transmission loss between the both 1 and 2. be able to. With this configuration, the stability of transmission control between the wheel 1 and the passive wheel 2 can be enhanced.
