Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an article supply device that automatically takes out electronic components from a stick-shaped storage container in which a series of electronic components are stored, for example.

(Prior Art) Electronic components such as IC chips are stored and packaged in a series in stick-shaped storage containers.

Conventionally, as a device for taking electronic components out of a storage container for inspection, secondary processing, or use, a method has been adopted in which the storage container is held vertically and the electronic components are taken out from the bottom of the container by falling under its own weight. ing.

For example, in a take-out device commonly referred to as a handler or mounter, the IC sticks are tilted vertically toward the take-out position, so that the IC chips can be taken out one by one by their own weight.

(Problems to be Solved by the Invention) However, with this structure, when setting the IC stick in the device, the working position is high, making it difficult to work.

Additionally, in order to increase the number of parts supplied per unit time, it is necessary to install the main parts of the mechanism in a high position, and the rigidity of the neck mounting body must be increased to support those limbs. Although the work efficiency was low, the equipment was large and heavy.

Furthermore, in this type of retrieval device, the position conversion ii
must be added, making the equipment more complicated and
There was a drawback that the conveyance speed was reduced due to the conversion work.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide an article feeding device that improves the workability of the device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the article supplying device of the present invention includes a container storage means in which a plurality of storage containers each containing a series of articles are loaded and stored. a moving means for moving the container storing means to a position where one of the storage containers stored in the container storing means faces the article take-out position; and a storage container moved to the article take-out position by driving the moving means. The present invention is characterized by comprising a holder for positioning and fixing an item, and a take-out means for taking out an article from a storage container positioned by the holder.

(Function) The storage containers stored in multiple stages in the storage means are taken out one by one and positioned at the removal position (oddly, the electronic components stored inside are sent one by one to the conveyance side in a separated state. After discharging the electronic components, the storage container is fed into the empty container discharge chute and the next storage container is located in the removal position.

(Embodiment) Hereinafter, an embodiment of the present invention will be explained in detail with reference to the drawings. Fig. 1 is a front view of the take-out device of the present invention, Fig. 2 is a plan view thereof, and Fig. 3 is a left side view thereof. be.

In the figure, this ejecting device includes a storage container, i.e., container storage means, i.e., a magazine 2, in which sticks 1 are stored vertically in multiple stacks in a horizontal state, and a moving means, i.e., a lift, for pushing up the sticks 1 to the component ejection position of the magazine 2. 3, and cylinders 48 for holders, which are arranged opposite to each other on both sides of the parts extraction position, that is, the top, and position and fix the stick 1. and a support cylinder 4b, and an extraction means for extruding a row of IC chips 5 from a fixed stick 1, that is, an extrusion cylinder 6;
An empty container discharge chute 11 is provided on the side of the device and accommodates an empty stick from which the IC chip 5 has been discharged.

This feeding device also includes a transport guide 8 that simultaneously and sequentially transports the extruded IC chips 5 to the component transport side along the transport rail 7, and a transport guide 8 that separates the rows of IC chips 5 one by one at the component transport standby position. A separating means, ie, a pair of separating rollers 10, is provided for releasing the paper into the conveying section 9 in a state in which the paper is separated.

The stick 1 is a rail-shaped container made of foamed plastic with a concave cross section, both ends of which are open, and a large number of IC chips 5 arranged in tandem inside.

The sticks 1 are stacked in multiple stages in a cassette-type holder 12 and set in the magazine 2. Then, by driving the drive motor 13 at the bottom of the device, the lift 3 is raised, and the stick 1 at the top is raised to the take-out position.

At the take-out position, the plungers of the holder cylinder 4a and the support cylinder 4b protrude from both sides to clamp and fix the stick 1.

Each of these cylinders 48, 4b also functions as a means for removing the stick 1.

In the fixed state, the plunger of the extrusion cylinder 6 is positioned opposite to the concave portion of the stick 1, so that the IC chips 5 can be extruded all at once onto the transport rail 7.

The conveyance guide 8 presses the top surface of the row of IC chips 5, and is connected to a support 15 movably arranged on a linear ball guide 14 fixed parallel to the lower side of the conveyance rail 7. There is.

The rack 15 is mounted on a pinion 17 that is connected to the output shaft of a moving motor 16.

The operation of each part of the automatic ejector for electronic components of Oke-sei described above is detected by a sensor V, etc., and it operates according to a predetermined program based on the detection result. explain.

FIG. 4 is a flowchart showing the operating order of the apparatus.

First, after making the device operational, initial processing such as turning on the switch is performed (step 1), and the lift 3
moves upward, and when the top stick 1 is located at the take-out position, the lift 3 stops (steps 2 and 3).

In the stopped state, the plungers of the holder cylinder 4a and the support cylinder 4b, which are located at the original position, protrude from both sides to position and fix the stick 1 (
Steps 4, 5).

Next, the plunger of the extrusion cylinder 6 protrudes into the recess of the stick 1 and extrudes the IC chips 5 all at once onto the transport rail 7 (steps 6 and 7).

Upon receiving the extrusion completion signal, the plunger of the cylinder 6 retreats to its home position (step 8), and now the pinion 17
rotates to sequentially move the racks 15 in the standby position to the front side, and the pair of separating rollers 10 rotates (
Steps 9, 10゜11).

As a result, the IC chips 5 are sequentially separated from the front side and delivered to the transport section 9.

When all this work is completed, the holder cylinder 4a retreats, and the plunger of the support cylinder 4b moves forward, causing the empty stick holder 1 to fall into the ejection chute 11, thus completing the ejection cycle. (step 12.13).

Thereafter, the plungers of the holder cylinder 4a and the support cylinder 4b are retreated to their original positions in step 14.15>, and the operations from step 2 are repeated again.

The automatic extraction operation is repeated in this manner, and when all the holders 12 are emptied, a termination signal is output, and all operations of the apparatus are terminated (steps 16, 17 and 18).

Therefore, in this case, the same operation can be repeated by performing the initial processing of step 1 again.

In the embodiment, a case where the present invention is applied to take out an IC chip is shown, but it goes without saying that it can also be applied to take out electronic components or other articles housed in a series.

(Effects) As explained above, according to the present invention, since the articles are taken out sequentially, the articles can be continuously supplied over a long period of time, and the workability of the apparatus can be improved.

Moreover, since the article can be taken out in a horizontal state, there is little change in the posture of the article after taking it out, and this is useful for downsizing and simplifying the coupling system.
