Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer direction changing device for a transfer device such as a belt conveyor or a roller conveyor.

Conventionally, in the case of transfer devices such as belt conveyors and roller conveyors used to transfer objects in factories and warehouses, when changing the direction of transfer of the objects, as shown in Figure 1, A curved conveyor 33 is installed between the linear conveyors 31 and 32, and the objects to be conveyed are conveyed along the curve by rotating a group of conveying rollers 34 provided thereon.

However, in the case of conventional equipment, the conveyor 33
Because it has a curved shape, it occupies wasted space, and the conveyance distance becomes correspondingly longer, so it takes time to change direction. Furthermore, since each roller needs to be installed in a fan shape at a curved part, not only is the configuration cumbersome, but the drive mechanism for driving each roller is also complex, and there are disadvantages such as the need for frequent maintenance and inspection. It was hot.

An object of the present invention is to provide a transfer direction changing device which eliminates the above-mentioned drawbacks of the conventional devices.

Below, the embodiments of the present invention are shown in Figures 2 to 6.
This will be explained based on the diagram.

Reference numeral 1 indicates the entire transfer direction changing device disposed between the terminal end 2a of the first conveyor 2 and the starting end 3a of the second conveyor 3, and 4 indicates two sides corresponding to the terminal end 2a and the starting end 3a, respectively. It is a square machine base with 1a and 1b. This machine base 4 is provided with a girder frame 4a diagonally to divide the machine base into two, and within the isosceles triangle there are a number of girders 4a corresponding to the first conveyor 2 and the second conveyor 3. A first conveyance roller group 5 and a second conveyance roller group 6 are arranged, respectively. In the embodiment, the number of rollers for each of the conveyance rollers 5a, 6a is eight, but there is of course no limit to the number, and the machine base 4 does not necessarily have to be formed into a square shape, and as shown in FIG. As shown, the conveyance rollers may be installed alternately.

7 is a driving mechanism for driving the first conveying roller group 5, 8 is a driving mechanism for driving the second conveying roller group 6, and the third
In the illustrated example, bevel gears 9 and 10 are used, and motors 11 and 12 move the first conveying roller group 5 in the same direction as the feeding direction of the first conveyor 2, and The conveying roller group 6 is adapted to be rotated in the same direction as the feeding direction of the second conveyor 3.

FIG. 4A shows an example using a worm gear mechanism 13, and FIG. 4B shows an example using a belt drive mechanism.

Note that, due to the relationship between the rollers and the objects to be transported, it is not necessary to drive all the rollers to rotate, and the intermediate roller may be used as an idle roller.

In the figure, 5b and 6b are shafts of the rollers 5a and 6a, 14 is a drive shaft, and 15 is a belt.

An example of the operation when actually transporting an object in the above configuration will be explained based on FIG. 6.
As shown in FIG. 6A, the first conveyor 2 is constantly driven, and when the transported object E reaches a predetermined position, the sensor S ₁ detects this and the transport roller group 5 starts, and the transported object E
is transferred to near the center of the transfer direction changing device 1. Note that in this state, the conveying roller group 6 is stopped. When the conveyed object E is located at the center as shown in B, the sensor _S2 stops the operation of the conveying roller group 5 and starts the conveying roller group 6, and as shown in C, the conveyed object E is moved to the second conveyor. Transferred to the 3rd side. When the conveyed object E passes a predetermined position as shown in D, the conveying roller group 6 is stopped by the sensor _S3 and becomes in a standby state.

In the above embodiment, independent drive mechanisms are provided for each of the first and second transport roller groups, and by operating these independently, it is possible to transport the object to be transported while keeping the orientation constant. This is how it was done.

According to the transfer direction changing device according to the present invention, the first
It is installed between the terminal end of the second conveyor and the start end of the second conveyor provided in the opposite direction, and the first and second conveyors are installed so as to correspond to the first and second conveyors, respectively. A group of conveying rollers are arranged on a square machine base so as to divide the machine base into two, and by driving these, the conveyance direction of the conveyed object is changed.
By using the sensor to sequentially operate the first and second conveying roller groups,
This allows the object to be transported while maintaining its orientation constant. In addition, the time required to change direction is short, and unlike conventional ones, the roller arrangement
Since the drive mechanisms and the like for this purpose can be arranged linearly, the structure is simple, and there are advantages such as no need for frequent maintenance and inspection.

Claims (1)

[Claims for Utility Model Registration] The objects transferred by the first conveyor are transferred to a second conveyor located in a direction different from that of the first conveyor.
A transfer direction changing device installed between the end of a first conveyor and the start of a second conveyor for loading and conveying on a conveyor, the device having two sides corresponding to the end and the start, respectively. The machine is arranged in a square shape so as to divide the machine into two parts, and on the first conveyor side there is a first group of conveying rollers which are driven to rotate in the same direction as the feeding direction of the first conveyor. On the second conveyor side, a second conveying roller group that rotates in the same direction as the feeding direction of the second conveyor is installed. 1. A second sensor is provided, and a third sensor is provided for detecting that the object to be transported is on the dividing line between the first transport roller group and the second transport roller group of the machine base, When the first sensor detects the object to be conveyed, the first conveyance roller group is activated, and when the third sensor detects the object to be conveyed, the first conveyance roller group is activated and the second conveyance roller group is activated. A transfer direction changing device characterized in that the second conveyance roller group is stopped when a second sensor detects an object to be conveyed.
