Description

[Detailed Description of the Invention] [Industrial field of application] The present invention mounts a winding and feeding drum for winding and feeding a long body such as a rubber hose, and moves the drum while placing the drum. The present invention relates to a simple carriage used for winding or supplying a linear body to a drum mounted or placed.

[Conventional technology]

In the manufacturing process of rubber hoses and the like, for example, while forming an inner rubber layer on the outer periphery of a flexible long mandrel such as nylon with an extruder, the formed unvulcanized long body is wound on a plate or drum. In other words, in the next braiding step, the unvulcanized long body wound up is continuously supplied to the braiding machine.
Further, the unvulcanized long body after braiding is similarly wound around an empty drum or the like.

In the case of winding and feeding with a plate, since the winding capacity of the plate is very small, the length of a long body such as a rubber hose that can be wound or fed at once is limited. On the other hand, in the case of winding and supplying using a drum, since the winding capacity of the drum is large, there is an advantage that a long body such as a rubber hose that is much longer than a plate can be wound or supplied at one time.

However, moving the plates and drums requires the use of cranes, hawk lifts, etc., which is dangerous, time-consuming, and inefficient. Recently, a dolly is often used for moving the drum or winding or supplying the hose, but it is necessary to lift the drum by using a crane or the like for the work of putting the drum on or off the dolly. It was also accompanied by poor efficiency.

[Problems to be solved by the device]

In view of such conventional circumstances, the present invention provides a trolley capable of easily loading and unloading a drum without using a lifting device such as a crane, and further capable of moving with the drum loaded and winding or supplying a hose or the like. The purpose is to provide.

Side frames facing each other of the frame 5
A lever 9 is extended along the side frame 5a and supported by a pin 9 provided so as to face the pin 5a so that the pin 9 can be rotated about the pin 9.

At the end of each lever 8 on the drum entrance / exit 7 side from the pin 9,
The bearings 10 are fixed so as to face each other with their center lines orthogonal to the side frames 5a. A support shaft 11 is rotatably accommodated in each bearing 10, and a bearing handle 12 is separately mounted on the outside of the bearing 10.
By rotating (not shown in FIG. 1), the bearing 10 can be moved in and out of the side frame 5a. The support shaft 11 is adapted to be fitted into a central hole 4 opened in a shaft portion 3 connecting the two side wheels 2 of the drum 1, respectively.

When the drum 1 has a projecting central shaft, a cylindrical support shaft fitted to the outer periphery of the central shaft may be provided in the bearing 10 so that it can be taken in and out.

Also, the end of the lever 8 on the side of the central frame 5b with respect to the pin 9 has a connecting rod 13
The nut 14 is fixed to the center of the connecting rod 13. Further, a guiding screw rod 15 is inserted into the nut 14 and is provided so as to extend in a substantially vertical direction connecting the nut 14 and the center of the central frame 5b. As shown in FIG. 1, the lower end of the guiding screw rod 15 is connected to one side of the universal joint 16, and the other side of the universal joint 16 is rotatably supported by the central frame 5b in the vertical direction by a ball bearing or the like.

On the other hand, at the center of the central frame 5b, a lifting handle 17 having a rotary shaft extending horizontally is provided, and the rotary shaft is rotatably supported by the central frame 5b by a ball bearing or the like.
Further, as shown in FIG. 1, the rotating shaft of the lifting handle 17 is connected to the other end side of the universal joint 16 by a bevel gear 18, a worm gear or the like so that the lifting handle 17 can rotate. It can be transmitted to the guide screw rod 15 via.

[Action]

When the drum 1 is placed on the dolly, the guide screw rod 15 is first rotated by the rotation of the lifting handle 17, and the nut 14 inserted through this is raised. As a result, the lever entrance 8 on the side of the drum entrance / exit 7 descends, and the bearing 10 comes into contact with the stopper 19 adjusted to a predetermined height to stop. During this time, the nut 14 moves in an arc around the pin 9, but the guide screw rod 15 can be freely tilted and followed by the universal joint 16 at the lower end as shown in FIG. In this state, the carriage is moved, the drum 1 is inserted from the drum entrance / exit 7, and the carriage is stopped at a position where the center hole 4 of the drum 1 and the bearing 10 are aligned.

Next, the support handles 12 are respectively rotated so that the respective support shafts 11 are projected from the bearings 10 and fitted into the center holes 4 on both sides of the drum 1, respectively. In this specific example, the bearing handles 12 are provided separately on both sides, but one bearing handle 12 is provided on the central frame 5b so that an operator can operate it at the same place as the lifting handle 17, and the rotation thereof is performed. It is also possible to transmit these to the central shafts 11 on both sides using gears and bevel gears, and to take them in and out.

After the drum 1 is supported on the lever 8 by the support shaft 11, when the lifting handle 17 is rotated in the opposite direction, the guide screw rod 15 rotates in the opposite direction, and the nut 14 inserted through the guide screw rod 15 follows the guide screw rod 15. To descend. As a result, as shown by the alternate long and short dash line in FIG. 1, the lever rod 8 rotates about the pin 9 as a fulcrum, and the bearing 10 and the support shaft 11 rise, so that the drum 1 supported by this is lifted from the ground to the carriage. It will be in a loaded state. The drum 1 weighs several hundred kg when the rubber hose is wound up to the full capacity, but the lever 8
By this action, the drum 1 can be lifted relatively easily even manually.
