Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a device in which a carrier traveling on a rail receives a work having a directivity from a predetermined direction and transfers the work in a constant direction. The present invention relates to a transport device in which a traveling direction of a transport machine when viewed from a workpiece loading direction at the time of receiving a load is reversed from a normal traveling direction so that a workpiece can be unloaded in any direction.

2. Description of the Related Art As an example of a conventional transfer device, particularly a transfer device for receiving a directional work from a predetermined direction and transferring the work in a fixed direction, a transfer device used in a car body assembly line of a passenger car is shown in FIG. It will be described based on. According to the figure, the carrier swivels in the fixed direction of arrow 3 on the two rails 1 and 2 which are arranged in independent rings, respectively, and the four steps of load receiving, carrying, unloading and forwarding are performed in one step. An apparatus for conveying a work is shown as a cycle. This transfer device is used in a line where left and right side panels 4 and 5 assembled in their own lines are joined to a floor panel and sent out. That is, the left side panel 4 supplied to the load receiving step 8 from the loading direction of the white arrow 10 and the left side panel 5 supplied to the load receiving step 11 from the loading direction of the white arrow 12 are
Each of them is carried to the unloading process 9 by being placed on a carrier machine in a substantially horizontal state with the vehicle interior side facing upward. In the unloading process 9, after joining the side panels 4 and 5 which have risen substantially vertically from the above-mentioned loaded state to the floor panel loaded from another line not shown, in the direction of the white arrow 13. It is configured to be shipped.

Therefore, the left and right side panels 4 transferred to the unloading process 9,
The orientation of 5 is important, and if it is transported in the orientation in which it is received for the sake of layout, it may be unloaded in the opposite direction to the desired one, that is, in a direction in which the desired joining cannot be achieved only by standing up almost vertically. In such a case, a mechanical swivel device 14 has been provided in the middle of the transfer process, and the device is used to rotate 180 degrees on a horizontal plane to move the work forward and backward with respect to the transfer (transport device traveling) direction. I needed to change the direction.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the above-mentioned conventional example, a turning device including a drive unit and a control unit having a mechanically and electrically complex structure is used, and a workpiece once loaded is placed on a horizontal plane. Above
It was necessary to rotate 180 degrees to align the workpieces. However, such a swivel device is liable to cause a defect due to its complicated structure, and thus has a disadvantage that the swivel device causes a line stop.

Means for Solving the Problems The present invention is to solve the above-mentioned problems, and in a device in which a carrier traveling on a rail receives a directional work from a predetermined direction and conveys the work in a certain direction, A swinging part was provided in which a rail for transporting from a point intersecting with the work loading path to the work loading position was turned 180 degrees in a U shape on a horizontal plane, and the load receiving position was viewed from the work loading direction. The carrier device is characterized in that the direction of travel of the carrier is set to a position opposite to the intersection with the carry-in route.

Action According to the above-mentioned means, since the rail for transporting from the point intersecting the work-carrying-in path to the load receiving position of the work is provided with the turning portion which is turned 180 degrees in a U shape on the horizontal plane, The traveling direction of the carrier seen from the loading direction is
The left and right sides are opposite to each other before and after the turning portion. That is, when the carrier receives a directional work from a predetermined carry-in direction, the carry-in direction at the intersection of the carry-in path located in front of the swivel and the cross-in of the carry-in path located after the swivel. As the traveling direction of the transport machine is right and left as viewed from above, it is necessary to receive the work supplied from the predetermined direction at the intersection located after the transport machine traveling in a certain direction has passed the turning part. According to this configuration, the direction of the work placed on the carrier is reversed in the front-rear direction of the traveling direction, as in the case where the workpiece is loaded before passing through the swivel unit and turned 180 degrees on the horizontal plane.

Embodiment An embodiment of the work revolving structure of a transfer device according to the present invention will be described below with reference to FIG.

FIG. 1 shows a transfer device applied to a car body assembly line of a passenger car, and receives and transfers a load on two rails 1 and 2 each of which is formed by forming an independent ring-shaped circuit. , The unloading and forwarding are set as one cycle, and the transporting machine turns in the fixed direction of arrow 3. This transporter transports a directional work, for example, the left and right side panels 4 and 5 placed in a substantially horizontal state. Then, on the rail 1 that conveys the left side panel 4, U on the horizontal plane
There are two swivel parts 6 and 7 that make a 180-degree turn in a letter shape, and the side panel 4 is located at the position where the first swivel part 6 is passed.
Is arranged so that the side panel 4 received in the step 8 is conveyed to the unloading step 9 arranged at the position passing through the next swivel unit 7. That is, the first turning unit 6 purposely turns the rail 1 from the point A intersecting the work loading path (work loading direction 10) to the work loading position (load receiving step 8) in a U shape on the horizontal plane by 180 degrees. It was made to be provided.

In the loading step 8, the left side panel 4 is supplied from the carrying-in direction of the white arrow 10, and the right side panel 5 is supplied.
In the cargo receiving step 11 for receiving the cargo, the supply from the carry-in direction of the white arrow 12 is received. The white arrow 13 indicates the unloading process 9
It shows the direction in which the left and right side panels 4,5 that have been unloaded in step 1 are joined to a floor panel (not shown) and then carried out to the next step.

In the vehicle body assembly line for passenger cars described above, the orientation of the left and right side panels 4 and 5 at the position where they are carried into the unloading process 9 is important. Therefore, the left side panel 4 supplied from the carrying-in direction of the white arrow 10 is configured to be received at the intersection with the work-carrying-in direction 10 located after passing through the swivel unit 6, so that the front side of the swivel unit 6 is received. In comparison with the state in which the workpiece is received at the point A intersecting the workpiece loading direction 10, the workpiece is transported in a state in which the front and back are reversed with the direction changed by 180 degrees on the horizontal plane. That is, the side panel 4
At the point A as viewed from the carrying-in direction, the carrier machine travels from the left to the right (the same direction as arrow 3), while the cargo receiving step 8
Since the transport machine travels from right to left, when the side panel 4 having the same directional plan view at both points is placed on the transport machine, the front and back of the work in the traveling direction are in the opposite direction, The end result is similar to using a swivel device.

Then, by providing the next turning portion 7, the rail 3 which has become closer to the rail 2 at the turning portion 6 can be returned to the original route and directed to the target unloading step 9.
As a result, the left and right side panels 4 and 5 are both conveyed in a desired direction to the unloading step 9, and in the unloading step, the passenger compartment side at the time of loading is lower than the floor panel loaded from another line. 90 from an upward horizontal state to a vertical direction
It can be joined by rotating it once it has been rotated. The body parts thus assembled are carried out in the direction of the white arrow 13 and supplied to the next step.

Advantageous Effects of Invention According to the above-mentioned present invention, a turning device having a mechanically and electrically complicated structure is not required, and a work can be turned on a horizontal plane (reversal of a conveying direction) only by devising a rail arrangement. It will be possible. Therefore, as compared with the conventional swivel device having a drive section and a control section, the possibility of occurrence of a problem is extremely low, and there is a great effect in improving the reliability of the line.
If this is applied to a monorail carrier device, its reliability is further improved.
