Description

The present invention relates to a parts taking-out device for taking out parts from a storage unit in which a plurality of parts are stacked and stored.

In the product assembly line, for example, when taking out parts, workers take out the parts piled up in the parts storage area one by one from above and place them on the temporary stand, and the parts placed on the temporary stand are placed. It is grasped by an assembly robot and attached to the attachment target. The reason why the worker takes out the parts from the parts storage place is that the parts to be piled up are taken out in order from the top, so that the taking-out position changes each time and it is difficult for the work robot to take out the parts. Therefore, the man-hours for setting the parts including walking of the worker will increase, and the parts stacked in the lower part in the parts storage area will stay in the parts storage area for a long time, which may cause quality defects such as rust. was there.

Therefore, for example, a device for taking out stacked parts in order from the bottom has been proposed (see, for example, Patent Document 1). In this device, for example, as shown in FIG. 4, thin plate parts M100 are horizontally stacked and stored in the magazine 111, and a slit 111A capable of taking out one part is provided in the lower part of the magazine 111. , An extrusion mechanism 112 for pushing out the component M100 from the opposite side of the slit 111A is provided. According to this device, the extrusion mechanism 112 can extrude and take out the component M100 at the bottom of the magazine 111. However, in this device, for example, as shown in FIG. 4, even if the component M100 remains at the position extruded by the extrusion mechanism 112, the next component M100 can be extruded by the extrusion mechanism 112, so that the components M100 can be extruded from each other. There is a problem that the parts may collide with each other or the order of the parts M100 may be changed in some cases. Therefore, it is necessary to perform electrical control to confirm by a sensor or the like that the component M100 does not remain at the extruded position.

It is provided with a drawer means 12 movably arranged at the lower part. In addition, in FIGS. 1 to 3, the component M is represented by a rectangular shape with a satin finish. As the parts to be stored in the component taking-out device 10, it is preferable that the components do not overlap in the stacking direction when stacked. Specifically, for example, when the parts M are stacked, it is preferable that the uppermost position of the lower part M is not higher than the lowest position of the upper part M.

The storage portion 11 is fixedly arranged, for example, with respect to the gantry 13. At the lower part of the storage unit 11, an outlet 11A for taking out one take-out part M1 located at the lowest position among the parts M housed inside is provided. In the lower part of the storage portion 11, for example, an extrusion port 11B for pushing out the extraction means 12 in the direction opposite to the extraction direction is provided at a position facing the outlet 11A. At the upper part of the storage unit 11, for example, a supply port 11C for supplying the component M is provided inside the storage unit 11.

The withdrawal means 12 makes it possible to take out the take-out part M1 by placing the take-out part M1 and pulling it out from the take-out port 11A. The withdrawal means 12 is arranged on the back side in the withdrawal direction with respect to the take-out / mounting unit 12A on which the take-out part M1 is placed and the take-out / take-out part 12A. It has a support portion 12B that supports the stacked component M2 stacked on the ejected component M1 so that at least a part of the stacked component M2 is higher than the outlet 11A when pulled out from the outlet. This is to support the stacked component M2 by the support portion 12B when the take-out / mounting portion 12A is pulled out from the outlet 11A so that the take-out / mounting portion 12A is not pulled out from the take-out outlet 11A.

That is, the support surface of the support portion 12B is formed at a position higher than the mounting surface of the take-out mounting portion 12A, and the difference in height H1 between the support surface and the mounting surface is the height H2 of the component M. It is preferable that they are the same. When the take-out and mounting unit 12A is pulled out, the stacking component M2 can be stably supported by the support portion 12B, and the take-out part M1 pulled out by the take-out and mounting unit 12A is taken out and placed in a state where it remains without being removed. This is because even if the portion 12A is moved under the storage portion 11, the stacked component M2 can be placed on the ejected component M1 without causing the ejected component M1 and the stacked component M2 to collide with each other.

The drawer means 12 is formed, for example, in a plate shape, and a take-out mounting portion 12A is provided on the drawer side of the drawer means 12, and a support portion 12B is provided on the push-out side. Further, on the front side in the drawer direction with respect to the drawer mounting portion 12A, for example, a fixed convex portion 12C for preventing the movement of the take-out component M1 is provided. The take-out / mounting portion 12A is, for example, concave with respect to the support portion 12B and the fixed convex portion 12C. The drawer means 12 is, for example, movably arranged with respect to the gantry 13, and a part thereof is located at the lower part of the storage portion 11 so as to be movable in the direction opposite to the outlet 11A and the extrusion port 11B. There is. As a result, the take-out and mounting portion 12A is pulled out of the storage portion 11 from the take-out outlet 11A, and the support portion 12B is pushed out of the storage portion 11 from the extrusion port 11B.

The height of the take-out port 11A is higher than the height at which the take-out component M1 is placed on the take-out / mounting portion 12A, that is, the total height of the mounting surface of the take-out / mounting portion 12A and the height of the take-out part M1. , The height at which the take-out part M1 and one stacking part M2 are placed on the take-out mounting part 12A, that is, the height of the mounting surface of the take-out mounting part 12A, the height of the take-out part M1, and one stacking part. It is preferably lower than the total height with the height of M2. Further, the height of the extrusion port 11B is higher than the height of the support portion 12B, and the height at which one stacking component M2 is placed on the support portion 12B, that is, the height of the support surface of the support portion 12B and one. It is preferably lower than the total height with the height of the stacked component M2.

The component taking-out device 10 may also have, for example, a driving means (not shown) for moving the drawing means 12.

The component extraction device 10 can be used, for example, as follows. First, for example, as shown in FIG. 1, a plurality of parts M are placed in the storage unit 11 from the supply port 11C, stacked and stored. Then, for example, as shown in FIG. 2A, the take-out / mounting portion 12A of the pull-out means 12 is moved so as to be located below the storage portion 11. In the example shown in FIG. 2A, the pull-out means 12 is moved to the side opposite to the pull-out direction, the support portion 12B is pushed out from the extrusion port 11B, and the take-out / loading portion 12A is moved under the storage portion 11.

When the entire take-out / mounting part 12A is located under the storage part 11, for example, as shown in FIG. 2B, the part M moves downward, and one take-out part M1 located at the lowest position is taken out. It is placed in contact with the mounting portion 12A. Subsequently, for example, as shown in FIG. 2C, the extraction means 12 is moved in the extraction direction, and the extraction component M1 mounted on the extraction / loading unit 12A is pulled out and shown in FIG. 2D. As described above, the entire take-out mounting portion 12A and the take-out component M1 are pulled out from the storage portion 11. The pulled-out part M1 is removed by, for example, a working robot (not shown). By repeating this, one take-out component M1 located at the lowest position can be sequentially taken out from the storage unit 11.

Further, in the component extraction device 10, for example, as shown in FIG. 3A, the extraction component M1 pulled out by the extraction / mounting unit 12A remains without being removed, as shown in FIG. 3B. As described above, even if the take-out and mounting portion 12A is moved under the storage portion 11, the stacking component M2 is supported by the support portion 12B, so that the take-out component M1 and the stacking component M2 are taken out without colliding with each other. The stacked component M2 can be placed on the component M1. Further, for example, as shown in FIG. 3C, even if the entire take-out / mounting portion 12A moves under the storage portion 11, the take-out component M1 is placed on the take-out / mounting portion 12A. Therefore, the stacked component M2 does not move downward, and as shown in FIG. 3D, the ejected component M1 is taken out again by pulling out the take-out mounting portion 12A.

As described above, according to the present embodiment, the take-out mounting portion 12A on which the take-out component M1 is placed and the support portion 12B that supports the stacked component M2 so that at least a part thereof is higher than the outlet 11A. Since the pull-out means 12 provided with the above is movablely arranged, the take-out / mounting section 12A is moved under the storage section 11 to mount the take-out component M1, and then the take-out / loading section 12A is taken out from the outlet 11A. By pulling it out, the take-out part M1 can be taken out of the storage unit 11. Further, when the take-out and mounting portion 12A is pulled out, the support portion 12B supports the stacked component M2 so that at least a part thereof is higher than the outlet 11A, so that the stacked component M2 can be taken out. No. Therefore, it is not necessary to provide an electrical control means such as a sensor, and the components M can be reliably taken out one by one with a simple configuration.

Further, since the support surface of the support portion 12B is made higher than the mounting surface of the take-out mounting portion 12A by the height of the component M, when the take-out mounting portion 12A is pulled out, the support portion 12B is piled up. The component M2 can be stably supported. Further, even if the take-out part M1 pulled out by the take-out / mounting part 12A remains without being removed, the take-out / placing part 12A is placed under the storage part 11 as it is while avoiding a collision between the take-out part M1 and the stacked part M2. Can be moved to. Further, when the take-out part M1 remains in the take-out / loading part 12A, the stacked part M2 is not placed in the take-out / placing part 12A. Therefore, when the take-out / placing part 12A is pulled out, the take-out part M1 is pulled out again. , It is possible to prevent the order of the parts M from being changed.

Although the present invention has been described above with reference to embodiments, the present invention is not limited to the above embodiments and can be variously modified. For example, in the above embodiment, each component has been specifically described, but the specific configuration of each component may be different. In addition, it may not have all of the above-mentioned components, or may have other components.
