Abstract

PURPOSE: To provide a small press-moving device which has excellent handling performance and moves a large heavy object such as a wound coil by journaling front and rear rollers to both lower side plates, mounting driving rollers onto both upper side plates, and liftably-jointing both the upper and lower side plates through an inclined parallel link. CONSTITUTION: The middle parts of right and left lower side plates are integrally-jointed through two lower front and rear connecting rods 2, 2', and a front roller 3 and a rear roller 4 are journaled 5 so as to rotate loosely between the lower side plates 1, 1'. A bottom plate 13 is provided on the rear part of the rear connecting rod 2', and one caster 14 is mounted at the lower surface of its middle part. Just above the lower side plates 1, 1', upper side plates 6, 6' are disposed at an interval (s), and a part between both the upper and lower side plates 1, 6 is jointed by forward and downward inclining parallel links 11, 11. A driving roller 8 is rotated through an endless chain 22 engaged between a small gear 20 and a large gear 21 for reduction by the power of a reduction motor 10, and a wound coil or the like which is brought into contact with the driving roller 8 is rolled for movement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material such as a large automobile, a large airplane, a train on a rail or a winding coil such as kraft paper, which is supported by wheels and which is extremely heavy and cannot be rolled by human power. The present invention relates to a pressing movement device (roll pusher) for easily moving.

[0002]

2. Description of the Related Art In a conventional roll pusher, a drive roll and an idle roll are provided on a machine frame, and a base plate is provided so as to project from the middle of both side plates for supporting both rolls. Since it is provided, it is difficult to form the driving roll and the floating roll in a wide lateral width (horizontal width).

Therefore, the casters are suitable for loadless movement, but the pressure contact width between the drive roll and the pressed heavy wheel or the outer peripheral surface of the coil is narrow, and the drive transmission force is poor.

That is, in the above-mentioned prior art, while the drive roll is sufficiently in parallel contact with the outer peripheral surface of the heavy wheel to be pressed, the heavy wheel must be manually pressed while holding the operating rod while rotating the drive roll. It was necessary to move the machine frame not only forward and backward but also left and right by the casters.

[0005]

SUMMARY OF THE INVENTION According to the present invention, even if the outer peripheral surface of the weighted wheel or coil to be pressed and the drive roller are slightly oblique to each other, the operation lever pushes the drive roller shaft and the weight wheel shaft. The driving roller and the rear idler wheel are in pressure contact with each other, and the heavy wheel or coil is easily pressed and rolled strongly, and when moving without load, the front roller can be easily moved by lifting it with the operating rod. Aim to get a roll pusher.

[0006]

In order to achieve the above object, the present invention connects the middle of two lower side plates with a lower connecting rod,
Before and after the connecting rod, front and rear rollers are supported by both lower side plates by a horizontal shaft, and two upper side plates are arranged directly above the lower side plates with a space therebetween. The middle part is connected by an upper connecting rod, a drive roller is installed on both upper side plates by a horizontal rotation shaft in a portion surrounded by the connecting rod and both upper side plates, and a reduction motor for a driving roller is provided at a rear part of the upper connecting rod. Is supported between both upper side plates, the upper and lower side plates are connected by a front downward inclined parallel link so as to be able to move up and down, the drive roller is supported in contact with the front roller, and the drive roller is lifted from the rear roller with the above-mentioned interval And a lower plate provided between the lower side plates with one caster, and an operating rod extending upward on the bottom plate.

[0007]

In the present invention, when the switch lever provided on the upper end handle of the operating rod is grasped and the switch is turned on, the deceleration motor operates, the drive roller is rotated in the direction of arrow a, and the front roller contacting this is rotated by the arrow b. To move in the direction of arrow A on the floor. In this state, the rear portion is lifted by the force of the spring and the drive roller and the rear roller are not in contact with each other. The state is shown in FIGS. 2, 5 and 6.

The aircraft can be moved forward with the front roller in contact with the floor surface (FIG. 5), and by tilting the operating rod rearward, the rear roller and the caster are brought into contact with the floor surface to direct the aircraft. The conversion can be done. In that case, the rear roller is separated from the drive roller and is in an idle state,
The front rollers are elevated above the floor (Fig. 6).

The rear roller and the caster are brought into contact with the floor surface to move the machine body, and in this state, the drive roller is brought into contact with the heavy wheel to be pressed, and when the heavy weight wheel is pressed by the operating rod, the drive roller is parallel-linked by the reaction force. Tilts slightly backward and presses against the rear roller against the force of the spring. Then, the rear roller is rotated in the direction of arrow c.

In this state, the front roller floats above the floor surface, the drive roller rotates in the direction of arrow a, and the rear roller rotates in the direction of arrow c to push the heavy wheel in the direction of arrow A. Since the heavy wheel is rotated in the direction of arrow a,
Can be moved in any direction.

When the drive roller is pressed against the heavy wheel in an obliquely intersecting state, the caster can be moved to the left and right to correct the caster in parallel.

[0017]

As described above, according to the present invention, a horizontally long drive roller and front and rear rollers can be provided between the upper and lower both side plates, and the drive roller comes into contact with the pressed weight wheel or coil or the like and the rear roller. The heavy wheel or coil is rotated forward, and the drive roller rotates the rear roller in contact with the floor forward to advance the machine body. Therefore, the heavy wheel or coil can be rolled forward without any movement. Instead, when the rear caster is brought into contact with the floor surface under no-load operation, the drive roller separates from the rear roller by the force of the spring, the rear roller becomes free, and the front roller floats above the floor surface. There is an effect that the direction of the machine body can be easily changed by operating the operating rod and swinging the casters left and right.
