Abstract

PURPOSE:To allow the piled and stored thin parts to be separated and supplied one by one from the upper part by constituting the captioned apparatus from an adsorbing pad part for vacuum adsorption and a pressing pin part urged by a spring. CONSTITUTION:An adsorbing pad part 5 is constituted of an elastic adsorbing pad 7 and a holder 8, and a tube 9 connected to a vacuum apparatus is inserted into one edge of the holder 8. A pressing pin part 6 is constituted of a pin 10, a spring 11 for always urging the pin 10 downward, holder 12 for holding the pin 10 in slidable ways, and a stop ring 13 for preventing the slip-off of the pin 10. A separating feeding chuck part 3 lowers to adsorb a retainer 1, and the adsorbing pad 7 contacts with the retainer 1, and the pin 10 is set at the height equal to that of the adsorbing pad 7 through the deflection of a spring 11. When the adsorbing pad 7 vacuum-adsorbs the retainer 1, and the chuck part 3 rises, the pin 10 is returned by the spring 11, and the retainer 1 is put into bent state. Because of said bending, the succeeding retainers 1 are separated, and only one retainer can be adsorbed certainly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to stacking stocked thin parts from the top.
This relates to a device that separates and supplies sheets one by one.

Structure of the conventional example and its problems The conventional chuck 1 simply has suction pads 1a of the same height, as shown in a specific example in FIG.

With such a configuration, when thin parts are attracted, there is a problem that two or more thin parts are attracted due to the dust, static electricity, and adhesion of the objects to be attracted.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned conventional drawbacks and increases the reliability of separated supply.

Structure of the Invention The present invention comprises a suction pad section that vacuum-suctions thin parts, a presser bottle section that is placed at an appropriate position and is biased by a spring to bend the attracted thin parts, and a chuck that holds them. It consists of a main body and increases the reliability of separate supply of thin parts.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

One embodiment is an apparatus for separating and supplying retainers of an 8-track cartridge one by one.

In FIG. 2, retainers 1b are stacked in a magazine 2, and are inserted one by one into an 8-track cartridge by a separate supply chuck section 3.

FIG. 3 is a plan view of the separation supply chuck section 3, and FIG. 4 is a developed cross-sectional view taken along the line A-B.

6 is a suction pad portion, and 6 is a presser pin portion. The suction pad section 5 is composed of an elastic suction pad 7 and a holder 8, and a tube e connected to a vacuum device is inserted into one end of the holder 8. The holding pin section 6 is composed of a pin 10, a spring 11 that always urges it downward, a holder 12 that slidably holds the pin 1o, and a retaining ring 13 that prevents the pin 10 from slipping out. . Reference numeral 14 denotes a chuck body, which holds four suction pads 6 and four presser pins 6 in a 900 distribution. Regarding the height relationship between the suction pad section 5 and the presser pin section 6, the lower surface of the presser pin section 6 is held at a slightly lower position than the lower surface of the suction bow section 6.

Next, the operation will be explained.

The separation supply chuck section 3 descends to attract the retainer 1, the suction pad 7 contacts the retainer 1 as shown in FIG. 5, and the pin 10 becomes at the same height as the suction pad 7 as the spring 11 is bent. Next, when the suction pad 7 vacuum-chucks the retainer 1 and the chuck portion 3 rises, the pin 10 is returned by the spring 11 and the retainer 1 is brought into a bent state, as shown in FIG. Due to this bending, the second and subsequent retainers 1 are separated, and only one retainer 1 can be reliably attracted.

Effects of the Invention As described above, the present invention securely separates thin parts by adsorbing them and bending them.
