Description

TECHNICAL FIELD The present invention relates to a perforated part assembling apparatus for assembling a plurality of perforated parts to a rod implanted in a work.

Problems to be Solved by Prior Art and Invention Recently, an automatic assembling apparatus using a pallet conveyor has been widely used in order to reduce the cost of products, stabilize the quality, and save labor. In this type of automatic assembling apparatus, a desired work is generally placed on a pallet and stopped at each station to assemble one part at each station. For this reason, the work has a rod in which it is planted upright, and when a plurality of perforated parts are installed on this rod, a station is required for each perforated part to be installed, and the number of stations is large. As a result, there are drawbacks such as an increase in the size of the device.

Means for Solving the Problems The present invention is intended to eliminate the above-mentioned drawbacks.A retractable elastically urged ball is provided at the bottom near a work table on which a work having an upright rod is arranged. Arrange a mounting table with its pilot rod standing upright and held so that it can be pulled out, and feed the perforated parts up to the tip so that the holes are upright as they approach the mounting table. At least one component supply device having a chute part having a hole is provided, and a space larger than the hole of the perforated part is cut at the tip of the chute part, while the pilot rod and the part are cut. At least one stack unit that moves between the tip of the chute of the supply device is provided, and this stack unit has a ball at the bottom that is elastically urged to be able to retract It consists of an extruding sleeve that moves along the lock pin and a small cylinder that advances this extruding sleeve.It also moves between the pilot rod and the work rod arranged on the workbench and opens and closes by the operation of the cylinder mechanism. There is provided a chuck unit having a chuck claw for holding the pilot rod, a guide sleeve located below the chuck claw for guiding the pilot rod, and a small cylinder for advancing the guide sleeve in a direction away from the chuck claw.

Action In the above device, a work having an upright rod is placed on a workbench, and then a perforated component is supplied to the tip of the chute portion of the component supply device. Then, the stack unit is positioned above the chute portion of at least one component supply device, its stack pin is lowered so as to pass through the hole portion of the perforated component, and then immediately raised. At this time, the ball under the stack pin is located below the perforated component, and the perforated component can be locked. In this state, the stack unit moves above the predetermined pilot rod of the mounting table to lower the stack pin. When the stack pin comes into contact with the upper end of the pilot rod, the small cylinder operates, the pushing sleeve descends, and at least one perforated part held by the stack pin is pushed down from the stack pin and transferred to the pilot rod. It

After the transfer is completed, when the small cylinder returns and the stack unit returns to the original position, the chuck unit moves above the pilot rod and descends toward the pilot rod. At this time, the guide sleeve at the tip of the chuck unit is lowered by a predetermined distance while inserting the upper part of the pilot rod, and the upper end of the pilot rod is positioned between the chuck claws. After that, when the small cylinder operates and the chuck jaws hold the pilot rod, the chuck unit rises and pulls out the pilot rod from the mounting table, and while holding a predetermined number of perforated parts on it, above the work on the work table. Move up to.

When the chuck unit reaches above the work, the chuck unit descends again, and lowers the tip of the pilot rod until it abuts on the upper end of the rod of the work. Then, the small cylinder is operated to advance only the guide sleeve, and the perforated part held by the pilot rod at the tip of the guide sleeve is transferred to the work rod. After the transfer is completed, the small cylinder moves back, the chuck unit also rises and returns to the original position, and the assembly of the perforated parts is completed.
