Description

  The present invention relates to a transport apparatus, and more particularly to a novel improvement for transporting a transported object by a transport plate via a pulley disposed at a low position on a floor.

Examples of this type of conveying apparatus that have been used conventionally include the configurations of FIGS. 6 and 7 disclosed in Patent Document 1 and the configuration of the belt conveyor disclosed in FIG. 8.
That is, in the roller conveyor apparatus disclosed in FIGS. 6 and 7, what is indicated by reference numeral 1 is a roller conveyor apparatus having a configuration in which a plurality of rollers 2 are arranged along the longitudinal direction of the gantry 3. The gantry 3 is configured by connecting a plurality of first and second gantry units 3a and 3b in series.

First and second sensors 4 and 5 for detecting the transport (passage) position of the object W transported on each roller 2 are provided at positions downstream of the respective base units 3 a and 3 b of the base 3. Yes.
A plurality of drive motors 7 are provided on the outer surface 6 at the top of the gantry 3, and the drive motors 7 are configured to drive the rollers 2.

In some cases, the drive motors 7 may be attached to the respective rollers 2, but in FIG. 6, one roller 2 is skipped and driven every other roller.
The roller shaft 2 a of the roller 2 is configured to pass through the upper portion of the gantry 3 and be connected to the motor shaft 10 (shown in FIG. 7) of the drive motor 7.

A part of the gantry 3 is provided with a control unit 20 for inputting various signals from the drive motors 7 and the sensors 4 and outputting the drive signals.
As shown in FIG. 7, as an example, the drive motor 7 will be described as a two-phase step motor using a three-phase inverter output signal of an AC three-phase inverter as a synchronous motor (synchronous motor). As is well known, a two-phase step motor using this AC three-phase inverter power supply is provided with a rotor 13 having teeth on a motor shaft 10 provided on a case 12.

  Therefore, in the above-described configuration, when the object W is placed on the roller 2 and the drive motor 7 is driven, the object W is conveyed along the direction of the arrow by the rotation of each roller 2.

  Next, in the case of the belt conveyor of FIG. 8, a belt 21 is stretched endlessly between a pair of sprockets 2 and 2 that are driven by power of a motor or an engine (not shown), and is placed on the belt 21. The object W that is the object to be conveyed is configured to be conveyed in the direction of the arrow by the endless rotation of the belt 21.

JP 2005-104656 A

Since the conventional roller conveyor device and the belt conveyor are configured as described above, the following problems exist.
That is, in the case of the roller conveyor device shown in FIGS. 6 and 7, the long roller 2 must be suspended between the pair of bases 3 and 3, and the size of the object W that is the transported body is changed. In such a case, the size of the roller 2 must be changed, and the installation of each mount 3 must be changed, which requires installation work on the floor surface in the building.

In the case of the belt conveyor of FIG. 8, the most frequently used means for conveying the object W is the floor surface because the diameter of the sprocket 2 to which the belt 21 is applied is relatively large in the belt conveyor. It is difficult to reduce the height H from the belt 21 to the upper surface of the belt 21. For example, when an object W such as a vehicle is transported, the object W being transported is transported at a high position. It was in a dangerous state.
Therefore, it was necessary to dig a height groove on the floor and bury a belt conveyor, and the construction itself was not easy.
In the case of a belt conveyor, since the width of the belt 21 itself is fixed, when the width of the object W is changed, the floor must be dug up and replaced with another belt conveyor. The work required a great deal of effort.
In addition, when the weight of the object W to be transported is significantly increased, if the motor is insufficient in torque, it must be replaced with a torque-up motor, and the labor required for the replacement is also great. There was also a need to redesign.
Further, since the belt 21 is always driven, power is wasted when the number of objects W to be transported decreases.
