Abstract

PURPOSE:To enable works involved to be simplified so as to highly augment a work efficiency by configurating a device in such a manner that articles which form roughly a line, are stuck by vacuum closely at their center of gravity and then are transferred to a magazine which is excited through a guide mask equipped with a taper guide surface. CONSTITUTION:A table 1, on which an article 2 to be transferred is placed, is set just underneath a transfer starting point of a base 15 allowing the article to be stuck to a pad 10 closely at the center of gravity of the article 2 with both a cylinder 16 and a vacuum source 13 activated. Then, the pad 10 is elevated, and is moved onto a magazine 3 by means of a ball screw 18. Subsequently, the pad 10 is lowered onto a guide mask 24, then the vacuum is released. Accordingly, this casues the article 2 to fall down into a housing groove 4. Then, the magazine 3 is excited to the X direction by a feeder 21. This allows the article 2 to be guided and housed in the housing groove 4 of the magazine 3 along a taper guide surface 23. This configuration enables the simple configuration of a device to be employed associated with a highly augmented work efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an article transfer device for transferring articles that have been aligned to some extent into storage grooves of a magazine that have been perfectly aligned.

[Prior art and problems of this invention]

As shown in FIG. 7, when the articles 2 arranged on the table 1 or in the tray in a certain shaded position are transferred into the aligned storage grooves 4 of the magazine 3, depending on the shape of the transferred articles, the The method used is to manually transfer items one by one. As shown in the figure, in a case where the shape of the article 2 and the storage groove 4 are the same, if a general transfer device is used, the article before being transferred is slightly misaligned and cannot be properly placed in the groove 4. On the other hand, as a countermeasure to this problem, if a sensor for detecting the position of the storage groove and a position adjustment mechanism for the transfer means are added to the transfer device, since the positions of multiple articles are irregularly shifted before being transferred, each article is transferred to the destination one by one. This is because manual work is actually more efficient.

However, manual transfer is complicated and there are limits to improving efficiency.

The second invention is an article transfer device that has been made for the purpose of simplifying such work and increasing efficiency.

[Means to solve the problem]

The transfer device of the present invention includes a plurality of vacuum pads that individually and simultaneously adsorb the vicinity of the center of gravity of transferred articles aligned to some extent, a means for lifting and lowering the vacuum pads, and a means for horizontally moving the articles;
It has a plurality of sets of opposing tapered guide surfaces in the horizontal uniaxial direction whose upper ends are widened, and the lower ends of each guide surfaces are aligned with the opening edge of the article storage groove provided on the top surface of the magazine to form a vacuum pad movement path. It consists of a guide mask that is set on the magazine placed below, and a feeder that vibrates the magazine horizontally in two axes perpendicular to the horizontal l-axis.

[For production]

According to the apparatus of the present invention having such a configuration, a plurality of articles are transferred onto a magazine by a plurality of vacuum pads,
It is guided by the guide surface of the guide mask and falls into the storage groove of the magazine.

In addition, since the guide surface of the guide mask only has a guiding function in the l-axis direction, some of the articles misaligned in the two horizontal axes will get caught on the edge of the storage groove, resulting in incomplete storage. Since vibration is applied in two horizontal axes directions, it is finally stored reliably in the storage groove.

In addition, the reason why the position of the article is corrected in two horizontal axes by vibration is that when a guide surface in two horizontal axes is added to the guide mask, correction forces in one and two axes act simultaneously, causing unexpected This is to avoid such inconveniences, since a component force in the direction may occur and the position correction may become uncertain.

〔Example〕

Embodiments of the present invention are shown in the attached FIGS. 1 to 6.

Reference numeral 10 in FIG. 1 denotes a vacuum pad attached to the support plate 11 in a manner that matches the arrangement pitch of the storage grooves 4 attached to the magazine 3, and each pad is connected to a vacuum source 13 via a flexible hose 12. has been done.

Further, the support plate 11 is supported by a transfer base 15 via a guide rod 14 so as to be able to move up and down, and is raised and lowered by a cylinder 16 on the transfer base.

Further, the transfer base 15 is supported by a ball screw 18 suspended between opposing stands 17 and 17 and a guide rod (not shown) parallel to the ball screw 18, and a ball screw 1 screwed onto the side.
8 is rotated by a motor 119 to horizontally move it in the X-axis direction shown by the arrow.

On the other hand, a feeder 22 is provided directly below the end of the movement path of the base 15, and a drive source 20 vibrates the table 21 in the y-axis direction, which is horizontally orthogonal to the Retained. Furthermore, as shown in FIGS. 3 and 4, a guide mask 24 is fixed on the magazine 3, which has opposing taber guide surfaces 23 in the X-axis direction that expand upward and are provided in correspondence with each storage groove 4. Set. Opposed guide surface 2 of this guide mask
3 is a size that matches the width of a part of the storage groove 4 at the lower end.

The apparatus consisting of the above is used as follows.

That is, after setting the table 1 or tray on which the transferred article 2 is placed directly below the movement start point of the base 15, the cylinder 16
Then, the vacuum source 13 is activated, and the lowered vacuum pad 10 attracts the center of gravity side of the article 2 (FIG. 2). Next, raise the vacuum pad 10 and press the button.

- Transfer the vacuum pad holding the article onto the magazine 3 by rotating the screw 18. After that, when the pad comes down and the article 2 comes close to the mask 24 shown in FIG. 3, suction is stopped and the article 2 is dropped toward the storage groove 4. At this time, when the article 2 is displaced in the X-axis direction with respect to the groove 4, the article hits the inclined guide surface 23 of the mask as shown in FIG. 4, and falls into the groove 4 guided by this surface.

On the other hand, the position of the article 2 has not been corrected at all in the y-axis direction, so that the article whose position has shifted in the y-axis direction is partially caught on the opening edge of the groove 4, as shown in FIG. It will be in an incomplete storage state. Therefore, the feeder 22 is then driven to give the article 2 vibration in the y-axis direction. As a result, the article 2 is gradually displaced in the y-axis direction and completely fits within the groove 4.

At this time, since the vibration of the feeder does not include a vertical component, an article that is completely accommodated in the groove 4 or an article that is incompletely accommodated as shown in Fig. 5 will not be pulled out of the groove. Not at all.

Note that the horizontal movement of the vacuum pad 10 is not limited to the X-axis direction.

Furthermore, the means for raising and lowering the pad and the means for horizontally transporting it are not particularly limited. For example, as shown in Figure 6,
It is also possible to provide a cylinder 16' that rotates around a vertical axis using a motor 19' and a gear mechanism 25, and to attach an arm 26 to the tip of the rod so that the support plate 11 can be directly held by this arm.

In short, any mechanism may be used as long as it can raise and lower the vacuum pad and move it horizontally.

In addition, the guide mask 24 can be operated manually or manually against the magazine.
It can be attached or detached automatically.

〔effect〕

As described above, according to the transfer device of the present invention, a plurality of articles are simultaneously transferred onto the magazine by the vacuum pad, and are reliably stored in the aligned storage grooves of the magazine by the functions of the guide mask and the feeder.

Therefore, the hassle of work is eliminated and work efficiency is dramatically improved.
