CONSTITUTION: An epicyclic reduction gear 81 is direct-coupled to the extension of the shaft 13 of a motor 1, and the outer shell of this epicyclic reduction gear 81 is formed into a gear case (driving roller) 82 having an internal tooth gear to perform reduction driving. A conveyor belt 4 is wound around the driving roller 82.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, transporting powdered medicines (single package) on a conveyor at a pharmacy of a hospital, or at a bank teller, passing and delivering a cash card, and supermarket. The present invention relates to a mini-belt conveyor used for so-called small article transportation such as article transportation for automatic bar code reading at a cash register, and a geared roller device used therefor.

2. Description of the Related Art FIGS. 3 and 4 are schematic layout diagrams showing an example of a conventional device of this type. In FIG. 3, 1 is a motor, 2 is a speed reducer directly connected to the motor 1, and 3 is an outer periphery. A drive roller (drive roller) 5 on which the conveyor belt 4 is suspended is a conduction belt or chain that is hung between the drive roller shaft 6 and the motor side shaft 7 via a pulley (not shown). is there. Further, FIG. 4 shows another conventional example, in which 1 is a motor, 2 is a speed reducing unit, and 10 is a pulley.

In the apparatus shown in FIG. 3 as described above, the motor 1 is driven to rotate the shaft 7 via the speed reducer 2, and this rotation is transferred to the roller via the transmission belt 5 and the pulley (not shown). It is used as a mini-belt conveyer for the small articles described above by transmitting it to the shaft 6 and rotating the roller 3 fixed to the shaft 6 as shown by the arrow A, and driving the belt 4 hung on the roller 3. Alternatively, the drive roller 3 may be positioned above and used as a mini roller conveyor. Moreover, in the manufacturing of FIG.
→ Deceleration unit 2 → Belt 4 is driven via pulley 10.

[0004]

However, in the above-mentioned device, since the speed reducing portion is directly connected to the motor, the size of the entire device is restricted by the size of these driving parts, and the overall size becomes large. Therefore, there is a drawback that it does not meet the demand for space saving and compactness.

The present invention has been made in order to solve the above problems, and provides a geared roller device and a mini-belt conveyor which are compact in space and compact in size.

[0006]

In the geared roller according to the present invention, a planetary gear speed reducer is directly connected to an extension of a motor shaft, and the planetary gear speed reducer is built in a gear case. It is a drive roller.

In the mini-belt conveyor according to the present invention, the planetary gear speed reducer is directly connected to the extension of the motor shaft, the planetary gear speed reducer is built in the gear case, and the gear case serves as a drive roller. A belt is hung on a driving roller.

[0008]

According to the present invention, the drive roller having the built-in reduction gear portion is directly connected to the extension of the motor portion, so that the rotation of the motor is transmitted through the reduction gear portion connected to the shaft thereof to the gear case on the outer periphery thereof. (Roller) is driven,
Provides a small and efficient geared roller.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1 and FIG. 2, reference numeral 1 is a motor portion, and 8 is a drive roller portion provided on the extension of the motor portion and incorporated with a speed reducer. That is, in the present invention, the driving roller and the speed reducing portion are integrally formed on the inner and outer circumferences, and the conveyor belt 4 is hung on the driving roller. The details will be described below with reference to the drawings. 1 and 2, 1 is a motor unit, 11 is a stator, 12 is a rotor, 13 is a shaft,
14a, 14b and 14c are bearings, and 15a and 15b are brackets on both sides. 8 is a shaft 13 of the motor section
Is a drive roller portion in which a planetary gear speed reducer 81 connected to the extension of the planetary gear speed reducer 8 is incorporated.
1 is a gear case that is directly connected to the outer periphery of the motor 1 and serves as a drive roller that is driven to rotate by decelerating the rotation of the motor shaft 13 via the planetary gear speed reducer. The conveyor belt 4 is hung on the gear case 82. In the figure, 83a and 83b are side plates, and 84a and 84b.
Is a support frame for the motor unit 1 and the drive roller unit 8,
Reference numeral 85 is a bearing, 86 is a fixed shaft, and 9 is a guide roller for the conveyor belt 4.

In the above-described device, when the motor 1 is rotated, the outer gear case (drive roller) 82 is decelerated via the planetary gear speed reducer 81 which is a speed reducing mechanism connected to the shaft 13. By rotating and driving the conveyor belt 4 hung on it, the article placed thereon is conveyed.

[0011]

As described above, according to the present invention, the planetary gear speed reducer is integrally incorporated in the gear case, and the gear case itself is decelerated and rotated to be used as a drive roller. As a result, it has many excellent effects as shown below. (a) No need for a transmission belt or pulley as in conventional equipment, (b) Therefore, there is no slip due to a belt, etc., and transmission of reduction gear output is reliable, (c) Reduction gear is assembled in the drive roller. Since it is complicated, space saving and compactness can be achieved. (d) As it is an integral type, it is easy to remove,
Easy to install on the conveyor body.
