Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic component supply device used in an automatic manufacturing line, and more specifically, a component supply means, a support means having two support parts attached to the component supply means, A direction including a linear guide rail part for moving one support part of the support means linearly in the transport direction and a bending guide rail part for bending and moving the other support part in the transport direction from an intermediate part. It consists of a converting means and a pressing means which is fixed to the direction changing means and presses the member supplying means, and is configured such that the member supplying means performs a linear conveying operation and a direction changing operation by the operation of the pressing means. This invention relates to an automatic member feeding device.

Recently, automation in factories has progressed, and various automatic component feeding devices are being used. The operation of supplying this component usually consists of picking up the component, transporting it to the mounting position, and installing it.The operation of transporting this component to the mounting position may consist of a horizontal conveyance motion and a direction change motion. many. In order to perform such operations, conventional devices are equipped with separate moving means such as motors, air cylinders, and rotary cylinders, which are capable of carrying out conveyance operations and direction changing operations, respectively. As a result, the equipment becomes extremely large considering the parts to be supplied, uses a large amount of electrical energy, and requires complicated electrical circuits because the transport operation and direction change operation are performed sequentially in response to respective confirmation signals. This resulted in frequent failures.

The present invention has been developed in view of the above-mentioned points, and the device has a simple structure by allowing the device to carry out both the conveying operation and the direction changing operation using a single pressing means in one direction.

This invention will be explained in detail below with reference to the drawings,
This invention is not limited to the following examples.

FIGS. 1A and 1B show the plan and side shapes of the automatic member feeding device, respectively. The general structure of this device consists of a member supplying means A, a direction changing means B on which the member supplying means A is movably supported, and a pressing means C fixedly attached to the direction changing means B.

The member supply means A includes an upper supply cylinder 1
and the supply rod 2 of the supply cylinder 1,
A fixing member 3 with a T-shaped cross section to which the supply cylinder 1 is attached at its lower part, a guide member 4 whose lower part is also fixed to the T-shaped fixing member 3, and a guide that communicates and moves within this guide member 4. It consists of a rod 5, a guide rod 5 and a bracket 6 which is fixed to the lower end of the supply rod 2 and is pressed downward by the supply rod 2. On the underside of the bracket 6 are two component suction pads 7, 7 is provided.

The direction changing means B consists of leg plates 8, 8' provided opposite to each other and a vertical rail plate 9 provided above the leg plates 8, 8', and the rail 9 has two rail grooves. 10, 10' are provided.

The pressing means C consists of a pressing cylinder 11 and a pressing rod 12, and a nut 13 for adjusting the stroke width of the pressing cylinder 11 is provided at the end of the pressing rod 12.

The connection structure of each means will be explained below with reference to FIG. 2.

The member supplying means A and the direction changing means B are connected using two slide plates 14, 14'.
That is, the rail grooves 10 and 10' of the rail plate 9 of the direction changing means B are clamped by the two slide plates 14 and 14', and the above-mentioned parts of the member supply means A are attached to this single slide plate 14'. This is for attaching the T-shaped fixing member 3. Fixed with two fixing pins 1
5, 15', fixing pin 15, 1
5' are the fixing holes of the slide plate 14 on one side, the bearings 16, 16' (shown by dotted lines in FIG. It is fixed by inserting the fixing hole into the fixing hole of the T-shaped fixing member 3, and the fixing position is as shown in the figure on the slide plates 14, 1.
4', and the two slide plates 14, 14' are located near the corner located on one diagonal of the rail plate 9.
It is supported so that it can be slid freely against. Note that the fixing pin 15' on one side is attached to the slide plate 1 on one side.
4 and fix the connector 17 at the same time.

The two slide plates 14, 14' have a portion in which the fixed pins 15, 15' and the bearings 16, 16' constitute a supporting means, and the fixed pins 15, 15' and the bearings 16, 16' are integrated. serve as supporting parts.

The connection between the pressing means C and the direction changing means B is such that one end of the pressing cylinder 11 is fixed to the leg plate 8', and the pressing rod 12 is connected to the connector 17.
It is fixed and carried out.

The operation of this device will be explained below with reference to FIGS. 1 and 3 to 6.

The state shown in FIG. 3 is the state in which the supply rod 2 is extended downward by the operation of the supply cylinder 1 from the state shown in FIG.
7 holds component X by suction. Next, supply rod 2
is returned to its original position. After this operation is completed (the state shown in Fig. 1), the pressing cylinder 11 is operated, and the pressing rod 12 presses the connector 17, thereby pressing the member supplying means A (the state shown in Fig. 1). 4) in the direction shown by the solid arrow in Figure 4). Component supply means A
The bearings 16, 16' are in the rail grooves 10, 1.
The member supplying means A moves horizontally until the bearing 16 on the moving direction side reaches the bent part 10a of the upper rail groove 10 and picks it up. The pads 7, 7 perform a so-called horizontal transport operation. The bearing 16 on the moving direction side is located at the bent portion 1 of the rail groove 10.
When the member supplying means A is further pressed after reaching 0a, the bearing 16 follows the shape of the rail groove 10.
moves upward, whereas the bearing 16' on the opposite side moves horizontally along the lower rail groove 10'. Therefore, the member supplying means A rotates (as indicated by the dotted line in Fig. 4). (in the direction indicated by the arrow). Fourth
The figure shows the state after a slight rotation, and Figure 5 shows the state when the rotation is complete.
6' is moved to a position slightly advanced from the lower part of the vertical portion 10b of the upper rail groove 10, and the process is completed.
As the member supplying means A rotates, the suction pads 7, 7 perform a direction changing operation.

The state shown in FIG. 6 is a state in which the supply rod 2 is extended from the state shown in FIG. 5, and in this state, the part X is supplied to and attached to the part to be mounted. After supplying the parts, the member supplying means A is returned to the state shown in FIG. 1 and performs the same operation as described above in order to supply the next part.

In the above operation example, the member supplying means A rotates 90 degrees, and the suction pads 7, 7 also change direction by 90 degrees. If it is fixed at the position shown by the dotted line in Fig. 4, the stroke width of the pressing cylinder 11 is adjusted, and therefore the rotation operation is performed with the member supply means A rotated a little more than the state shown in Fig. 4. I can complete it. That is,
The structure is such that the mounting position of the nut 13 can be adjusted to accommodate any position of the part to be mounted from the bottom to the horizontal direction.

In the above embodiment, the linear conveyance direction of the member supplying means is horizontal, but of course this direction may be any suitable direction, and it is also of course possible to use this apparatus by incorporating it into an industrial robot.

This invention is constructed as described above, and the conveying operation and direction changing operation of the member supply means are performed by using one pressing means.
Both the mechanical structure and the electric circuit structure are simple and can be made smaller, and they also have an energy saving effect.
