JPS6040320A - Feeder for plastic pins with compression spring - Google Patents

Abstract

PURPOSE:To provide secure feed of plastic pins with compression spring by putting them in alignment, supplying them to a feed cylinder by the use of compressed air through a flexible feeder tube, wherein the feed cylinder is movable in the directions up and down as well as to the left and right, and thereby preventing entanglement of springs. CONSTITUTION:When a feed cylinder 3 sinks to the plastic pin insert hole in an object placed on a jig 5, an escape shaft 12 will retract. At the same time, a solenoid valve 8 opens to push the plastic pins with spring retained in a feeder tube 1 in good alignment out to the pin insert hole in another object through the action of compressed air. Then the solenoid valve 8 is closed, and escape shaft 12 advanced to hold the pin, and then the feed cylinder 3 rises up to take stand-by position for subsequent supply. This will prevent entanglement of compression springs to provide sure parts feed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a feeding device for resin bottles with compression springs for assembling articles.

When resin bottles with compression springs used for assembling various articles are fed to an assembly line by a feeder, the compression springs become entangled and come off the pins, which may impede the assembly work of the articles. In view of this point, it is an object of the present invention to provide a supply device for resin bottles equipped with compression springs, which can feed compression springs in an orderly manner without entangling each other, and can reliably supply articles on an assembly line. That is.

[Structure of the Invention] The feeding device for a resin bottle with a compression spring of the present invention includes an axial through hole through which a resin pin with a compression spring passes, and a hole that enters and exits near the exit of the through hole in a direction perpendicular to the through hole. The tip of a flexible feeder tube, in which the resin pins with compression springs are inserted in an orderly manner with their heads facing in the same direction, is connected to the entrance of the through hole of the supply cylinder having an escape shaft by a joint, and the feeder tube The rear end is connected to a supply source of compressed air, and the supply tube is held by a bracket so as to be movable up and down and left and right.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the overall structure of the apparatus of the present invention.

In the figure, reference numeral 1 denotes a flexible feeder tube (nylon tube) for feeding a resin bottle with a compression spring, and its tip is detachably connected to a supply cylinder 8 by a push-in joint 2. 4 is a bracket that holds the supply tube 8, 05 is a jig that moves up and down, and 6 is an article into which a resin pin with a compression spring is inserted. The rear end of the feeder tube l is connected to a pressure reducing valve 7, the pressure reducing valve 7 is connected to a solenoid valve 8, and the solenoid valve 8 is connected to a pressurized air source 9. FIG. 2 shows a flexible feeder tube 1 in which resin pins 10 with compression springs as shown in FIG. 8 are inserted in an orderly manner with their heads facing in the same direction. As shown in FIG. 4, the supply cylinder 8 has an axial through hole 11 through which the resin bottle 1O descends, and below the through hole 11 is an escape shaft perpendicularly thereto that prevents the resin bottle 1O from descending. 12 are set up so that they can come in and out freely.

Next, its effect will be explained. When the article 6 is set on the jig 5 and positioned, the supply cylinder 8 is lowered into the resin bottle insertion opening 6a of the article 6. (Fig. 5) Next, escape axis 12
moves back to allow the resin pin 10 to descend freely. At this time, the solenoid valve 8 is opened, and the resin bottle 1O is pushed out by compressed air whose pressure is appropriately reduced and inserted into the article 6. (Fig. 6) When the insertion of the resin bottle 10 is completed, the solenoid valve 8 closes, the escape shaft 12 advances and presses the next resin bottle to prevent it from falling, and (Fig. 4) the supply tube 8 rises. and wait for the next item to arrive. When the resin bottle lO in the feeder tube l is used up, remove the one-touch fitting 2 and insert a new feeder tube l with the resin pin inserted.
Attach.

[Effects of the Invention] Since the device of the present invention has the above-described structure and function, it can feed the resin pins IO with compression springs in an orderly manner without the compression springs intertwining with each other, and can deliver the resin pins IO with compression springs in an orderly manner without the compression springs becoming entangled with each other. 0, which has an excellent effect of reliably inserting the
