Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a relatively small corner drive roller conveyor used for transporting small and light conveyed objects.

[Prior Art] A corner drive conveyor is used to convey an object by bending the conveyance direction at right angles, and is often used in combination with a small linear roller conveyor. By the way, this corner conveyor has a relatively complicated structure because it requires combining a large number of rollers with different directions (arranging directions) to form a conveying surface and driving each of them. For example, if you install a separate motor for each group of rollers with different orientations (total of 3 motors are used), or if you use a platform with one motor, bevel gears or flexible gears 3 (3) etc. The rollers are used to transmit the power of the motor to each of the roller groups.

[Problems to be Solved by the Invention] Since the conventional type of conveyor had the above-mentioned configuration, the mechanism was complicated, and as a result, maintenance and inspection were difficult.
Moreover, the cost had to be high. Furthermore, since the mechanism was complex, it could cause failures, and there were problems with durability. Here, the present invention uses only one driving motor, and can smoothly transmit the motor power without using a complicated transmission mechanism using bevel gears etc. as in the conventional type. It has a new configuration.

[Means for Solving the Problems of the Invention] The present invention includes an intermediate roller group disposed obliquely with respect to the traveling direction of the conveyed object between the first roller group and the second roller group disposed at right angles to each other. In the corner drive roller conveyor, only one prime mover such as an electric motor is provided below the roller group, and at least two transmission shafts are installed parallel to one sleeve line of the intermediate roller group, and the transmission shaft is At the same time as being driven by the motor, at least one of a group of intermediate rollers disposed parallel to the transmission shaft is driven via an appropriate conduction band, and at the same time, either of the two transmission shafts is driven in close proximity to the transmission shaft. All or part of the first roller group or the second roller group is driven by a conduction band that can be twisted, such as a round belt, through the transmission shaft of the second roller group, thereby achieving a simpler configuration than before. Each roller group can be driven separately and smoothly under the roller.

[Example] In the attached drawings, 1 is a frame constituting the base frame of the conveyor, 2 is a group of drive ports provided on the upper surface of the base frame, and the roller axis is in the direction of arrow A in FIG. For,
arranged at right angles. 3 is a middle gate roller group mounted at an angle of 45° with respect to the axis of the roller group 2;
A second roller group 4 is arranged so that its axis is perpendicular to the axis of the first roller group, and the conveyed object is moved in the direction 1. indicated by the arrow. : Has the function of carrying out. As shown in FIGS. 2 and 3, two wooden transmission shafts designated by reference numeral 5.6 are arranged parallel to the axis of J5 on the lower surface of the intermediate roller group 3, and each of these shafts is provided with a chain boiling shaft. 5a
, 6a are fixed, and a chain coil 7a is also attached to the output shaft of the electric motor 7 installed below the shaft 5.6, and a common endless chain 8 is suspended from these three chain wheels. . It goes without saying that an appropriate transmission mechanism such as a belt or a bobbin can be used in place of the chain and chain wheel.

On the other hand, between the transmission shaft 5 and a pulley 10 installed at the end of the shaft 2a of the intermediate roller 2, as shown in FIG. The bell 1-9 is tensioned to transmit the movement of the transmission shaft 5. Incidentally, in the illustrated embodiment, the pulley 1
The rotational force transmitted by the roller 0 is transmitted to another intermediate roller adjacent thereto via another pulley 11 attached to the shaft 2a and a belt 12 suspended from the pulley. That is, the pulley 13 is also attached to the adjacent intermediate roller 31, and the belt 1 is inserted between this pulley and the pulley 11.
2 so that the rotation of the transmission shaft 5 is transmitted to all of the grouped roller groups. The details of this point are clear from FIG. 4, and the figure shows each roller constituting the intermediate roller group 3 (general reference numeral) as an example, but the configuration of this part is different from that of the other roller groups 2. and 4
The same applies to In addition, in Figure 4,
A plurality of rollers 2b divided in the axial direction with respect to the roller shaft 2a
, 2c, 2d, etc. are shown, and the roller 2b disposed at the end is fixed to the shaft 2a via the uneven part 14, while the other rollers 2c, 2d, etc. are fixed to the shaft 2a. Although it is in a loosely fitted state, it is not necessarily necessary to have such a configuration. That is, the rollers other than the roller 2b fixed to the shaft 2a may be configured as a single roller without being divided, or all the divided rollers may be connected to the shaft 2a.
It may be fixed to a. Further, the electric motor serving as the power source may be replaced with another prime mover such as an internal combustion engine.

Furthermore, although the illustrated example shows a round belt 15 as a conduction band that requires twisting, a flat belt may also be used.

Next, a mechanism for transmitting the rotational force of the transmission shaft 5 to the first drive roller will be explained. When a part of the individual rollers constituting the first drive row 52 is shown enlarged in FIG. A round belt 15 is twisted and passed between the wire 4@5. After driving the first drive roller 21 in this way, the driving force of this roller is transferred to another pulley 11 attached adjacent to the pulley 10 and the adjacent second drive roller 21 via the belt 12 passed around this pulley. It is transmitted to the roller 22. That is, a driven pulley 13 corresponding to the pulley 11 is attached to the shaft end of the drive roller 22, and this pulley and the drive pulley 11
A belt 12 is placed between the two and the two to transmit power. Note that, without providing the above-mentioned transmission mechanism, all of the individual rollers constituting the first roller group may be directly driven via the transmission shaft 5 and the round belt 15 suspended from the transmission shaft. This applies not only to the first drive roller group but also to the second roller group.

The transmission mechanism for the second drive roller is also the same as described above, and the transmission shaft 5 in the part explained based on FIGS. 2 and 5 can be read as transmission: N+6. The explanation will be omitted.

Since the configuration of the present invention is as described above, when the single electric motor 7 installed on the bottom surface of each roller group forming the conveying surface is operated, the chain wheel 7a attached to the output shaft of the single electric motor 7 is activated. The driving force of the motor is transmitted via the chain 8 to a pair of transmission shafts 5.6 shown in FIG.

The rotation of the shafts 5 and 6 is transmitted via belts 9 and 15 to the intermediate roller group 3, the first drive roller group 2 and the second drive J roller group 4, and drives each of these roller groups at a preset speed. It acts to move the conveyed object in a predetermined direction.

[Effects] As described above, according to the present invention, each of the roller groups having different directions can be driven by a single prime mover, and in this case, a complicated transmission mechanism such as a bevel gear or a flexible joint can be used. Since it is possible to transmit rotational force with a simple configuration by simply hanging a belt, it not only contributes to reducing the weight of the entire device, but also
Maintenance and inspection will also become easier. Furthermore, the entire structure can be made compact, and in this respect as well, it is useful as a corner conveyor used in combination with a small-sized drive roller conveyor.
