The present invention relates to a component automatic transfer device for automatically transferring a small part to a predetermined assembly position, and in particular, the main focus is to provide a small size of the configuration and the accuracy of the operation.

In the past, various types of component conveying devices have been provided to provide a part of the production automation. Most of these components have a double assembly of a first cylinder for raising and lowering and a second cylinder for forward and reverse. It consists of a guide bar and a mounting bracket of each cylinder as a reference, the first cylinder holding the transfer object during the lowering operation, the second cylinder is advanced after the completion of the ascension, the first cylinder is lowered again to lower the parts After ascending, the second cylinder retracts to complete one cycle of product transfer.

However, such a configuration requires not only two cylinder driving sources to transfer the parts, but also the control of the related devices is complicated and causes a lot of malfunctions as the product transfer is performed in seven consecutive operations. There were various problems such as expensive people.

Accordingly, an object of the present invention is to provide a component automatic transfer device that performs a simpler, more compact, and accurate operation without the risk of malfunction, which can solve the conventional problems as described above, and will be described in detail based on the drawings. Is as follows.

As shown in FIGS. 1, 2, and 3, the rack 3 having the rod 21 of the cylinder 2 coupled to one side end is conveyed up and down by using the guide bar 4 inside the enclosure-shaped case 1. The rotating disk 6 is fixedly installed on the shaft front portion of the pinion 5 which is engaged with the rack 3 and idles on one side thereof, so that when the indentation operation of the cylinder 2 is performed, the rack ( While 3) moves up and down, the pinion (5) and the coaxial rotation disk (6) is to rotate in the forward and reverse directions.

In addition, a guide groove 81 having an arcuate surface 82 and a vertical surface 83 on both sides in the longitudinal direction of the bottom center portion in the transverse direction inside the case 1 in front of the rotating disc 6 is shown in FIG. A horizontal guide bar (7) through which one horizontal slider (8) is slidably coupled to the left and right is installed in a vertical form with the pinion shaft guide bar (4), and the same structure as in the prior art is located in the lower side of the horizontal slider (8). As a separate control device (not shown), a vertical guide bar 12 having a conveying product holder part 10 which is operated and controlled as a vertical slider 9 which protrudes the guide plate 91 on the upper side is installed up and down. Simultaneously with the sliding through the furnace, a compression spring body 11 for upward movement was provided between the vertical slider 9 and the horizontal slider 8 for ballistic movement.

In addition, while the cam follower 61 is firmly installed on one side of the upper side of the rotating disc 6, the upper end thereof is coupled with the guide groove 81 of the horizontal slider 8, and the cam follower 61 and Between the guide pins 91 of the vertical slider 9, the transfer lever 14 having the long hole 141 is hingedly installed at the upper side, and at the same time, the rear end portions of the guide pins 91 are left and right on both sides to be inserted and moved. Since the guide plate 13 having the vertical guide holes 131 and 133 and the horizontal guide hole 132 therebetween is installed at the rear side of the vertical slider 9, the rack 3 by the cylinder 2 is provided. When the rotating disc 6 is rotated by the action of the pinion 5 and the cam follower 61 fixed to one side of the vertical slider 9 is interlocked with the guide groove 81 and the transfer lever 14. The raising and lowering operation and the left and right conveying operation of the horizontal slider 8 are performed.

At this time, the circular arc surface 82 of the guide groove 81 has the same size as the radius of curvature of the cam follower 61 (see FIGS. 4 and 6), and the forward and reverse rotation angle of the rotating disc 6 is It is controlled by a separate limit switch (not shown) installed adjacent to both final positions.

Looking at the operation of the present invention configured as described above are as follows.

First, in order to hold the object to be conveyed to the holder part 10 of the conveying apparatus, the cylinder rod is protruded and the cam follower 61 of the rotation disc 6 as the rack 3 and the pinion 5 is shown in FIG. As shown in (a) and FIG. 5, it moves below the virtual horizontal center line (x-axis) to the right of a meteorological vertical center line (y-axis).

At this time, the cam follower 61 is adjacent to the circular arc surface 82 of the guide groove 81.

After completing the holding of the conveying object (not shown) in such a position, by pulling the cylinder rod to rotate the rotary disk 6 in the reverse direction, the cam follower 61 also rotates together, and the cam follower 61 Since the same radius of curvature is brought into contact with the circular arc surface 82 of the guide groove 81, only the feed lever 14 is moved upward by the distance "a" in FIGS. 5 and 6 without moving the horizontal slider 8. Will be moved.

Therefore, when the cam follower reaches the starting point of the vertical surface of the arcuate end, the vertical slider 9 pinned with the tip of the feed lever 14 and mounted as a compression spring body 11 protrudes upward from the vertical guide bar 12. It is positioned on the upper right of the vertical guide hole 131 of the guide plate 13 (see also Figure 4 (b)).

Subsequently, the rotating disk, that is, the cam follower 61, is rotated 180 degrees and is horizontally past the virtual vertical center line (y-axis) as shown in FIG. 4 (c) in a state of being joined to the vertical plane 83 of the guide groove 81. When moving to the point coinciding with the center line, the horizontal slider 8 is transported to the left side by the distance "c" of jet 5 degrees, and the transfer lever 14 moves the ascending distance by the distance "b" to the long hole 141 itself. While absorbing is transported to the left along the horizontal guide hole 132, when the camp lower 61 reaches the lower left dead center along the arc surface 82, only the vertical slider (9) by the feed lever 14 While descending by the distance "d", as a separate control device by operating the holder unit 10 is to hold the object to be placed on the floor (see Figure 3).

After the above operation is completed, the cylinder rod is protruded and the rotating disc is rotated in the forward direction. The vertical and horizontal sliders 9 and 8 return the opposite operation to their original positions, thereby completing one cycle operation.

The present invention is constructed and operated as described above. As one drive source (cylinder), the horizontal slider 8 and the vertical slider coupled to the inside thereof are combined to perform a position transfer operation of the product. By performing the transfer operation using the cylinder, the overall configuration is much simpler than the conventional transfer apparatus using two cylinders, while reducing the electrical control and wiring and piping work, improving the quality due to reducing the cause of malfunction during operation, By making the product small and light, it is easy to manufacture and has a special effect that can reduce the production cost.
