Description

[Detailed Description of the Invention] The present invention relates to a belt conveyor that is driven not by a motor pulley but by a motor fixed to a motor base.

Some belt conveyors are relatively small and have a small capacity, and are used to convey, for example, mechanical parts for assembly several tens of centimeters or 1 to 2 meters.

In such a case, since the motor A is placed in a relatively narrow space between machines, the motor A is placed below the belt B as shown in Fig. 5, so as not to waste space in the width. ing.

However, this kind of conveyor always requires space for the motor below the belt, which can get in the way, and when using multiple conveyors in succession, at least the bottom of the drive pulley (head pulley) The belt surface of the next conveyor that enters the belt must be located further below the motor, etc., which has the disadvantage of increasing the level difference.

In view of these points, the present invention makes it possible to freely rotate one end of the motor base that fixes the motor on the same axis as the drive shaft of the drive pulley. For example, when the motor is located above the belt, The motor base can be fixed at any position, such as at the lower position or at the lower position, thereby solving the above-mentioned drawbacks.

Hereinafter, embodiments of the belt conveyor of the present invention will be described with reference to the accompanying drawings.

The belt conveyor shown in Figs. 1 and 2 is a small one with a distance of several tens of centimeters between the drive pulley 1 and the tail pulley 2, a motor 3 with a capacity of several tens of watts, and is made of light alloy such as aluminum. Telescopic legs 5 are fixed to a frame 4 made of aluminum, so that it can be easily installed at any location. Motor 3 that drives drive pulley 1
is fixed on a rotatable arm-shaped motor base 6 that is mounted on the same axis as the drive shaft 1a of the drive pulley, and is connected between sprockets 7 and 8 attached to the drive shaft 1a of the pulley and the motor shaft 3a. The chain 9 is wound so that it can be driven. The arm-shaped motor base 6 can be fixed at any rotational position.

For example, as shown in FIG. 4, a large number of screw holes 10, 10 or long holes are drilled in the motor base 6 on a circular trajectory centered on the drive shaft 1a, and the set bolts 11 are inserted through the screw holes 10. screw it into place on the frame 4 of the conveyor. That is, screw holes 10, 10 are drilled at 30 degree intervals, and the screw hole 10 corresponding to the desired rotation position of the motor base is
Screw the set bolt 11 on.

In other drawings, 12 is a conveyor belt wound between pulleys, 13 is a motor base 6
14 is a switch box for the motor 3.

In the belt conveyor of the present invention, the motor 3 is normally positioned below the conveyor belt 12 or the frame 4, as shown in FIG. Then, depending on the circumstances of the installation location, etc., frame 4
If space is required below the motor base, or if multiple conveyors are used to transfer the article C, the motor base can be unlocked and moved to any rotation position, for example, as shown in Figure 3, the motor base Fix this so that it is directly above the drive pulley.

As a result, it is possible to minimize the height difference between the belt conveyor and the next belt conveyor, and to use the drive pulley protruding directly above the table.

In other words, in this invention, the motor base is rotatably supported on the same axis as the drive shaft of the drive pulley, so the distance between the axes remains unchanged at any rotational position, and it can be fixed at any desired rotational position. can be driven.

In addition, in the illustrated embodiment, the drive pulley 1
The shaft of the drive pulley is the drive shaft 1a that drives it, but it is also possible, for example, to fix a gear to the shaft of the drive pulley and drive another shaft with a gear that meshes with the drive pulley using a motor. In this case, the motor base 6 will be pivoted on the axis of another shaft provided with gears. The point is that the motor base should be rotatable on the same axis as the drive shaft that is directly transmitted from the motor.

As described above, according to the belt conveyor of the present invention, the three motor positions can be freely rotated depending on the installation location and usage conditions of the conveyor, compared to the conventional belt conveyor in which the motor is fixed at a predetermined position. It can be made extremely versatile compared to the previous one.
