Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a supply device for resin pins with compression springs for assembling articles. When resin pins 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 of articles. In view of this point, it is an object of the present invention to provide a supply device for resin pins 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 pin with a compression spring of the present invention includes an axial through hole through which the resin pin with a compression spring passes, and a through 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 movably up and down and left and right by a bracket.

Embodiments of the present invention will be described with reference to the drawings. 1st
The figure shows the overall configuration of the device of the present invention. In the same figure, 1 is a flexible feeder tube (nylon tube) that feeds the resin pin with a compression spring.
Its tip is connected to the supply tube 3 by the push-in joint 2.
It is detachably connected to. 4 is a bracket that holds the supply cylinder 3 and moves up and down. 5 is a jig, and 6 is an article into which a resin pin with a compression spring is inserted. The rear end of the feeder tube 1 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. 3 are inserted in an orderly manner with their heads facing in the same direction. The supply tube 3 is the fourth
As shown in the figure, there is a through hole 11 in the axial direction through which the resin pin 10 descends, and an escape shaft 12 is provided below the through hole 11 at right angles thereto so that it can freely move in and out. be.

Next, its effect will be explained. Article 6 on top of jig 5
After setting and positioning, the supply cylinder 3 descends into the resin pin insertion opening 6a of the article 6. (Figure 5)
Next, the escape shaft 12 is moved back to allow the resin pin 10 to descend freely. At this time, the solenoid valve 8 is opened, and the resin pin 10 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 pin 10 is completed, the solenoid valve 8 closes, the escape shaft 12 advances and presses the next resin pin to prevent it from falling, and (Fig. 4) the supply tube 3 rises. and wait for the next item to arrive. When the resin pin 10 in the feeder tube 1 is used up, the one-touch joint 2 is removed and a new feeder tube 1 with the resin pin inserted is installed.

〔Effect of the invention〕

Since the device of the present invention has the above-described structure and function, the compression spring-equipped resin pin 10 can be delivered in an orderly manner without the compression springs becoming entangled with each other, and can be reliably delivered to the article using a device with an extremely simple structure. It has an excellent effect when inserted.
