Description

[Detailed Description of the Invention] The present invention relates to an automatic parts supply device to a parts feeder that automatically supplies an appropriate amount of parts to the parts feeder.

Conventionally, the reality is that parts feeders have to be manually monitored to feed the appropriate amount of parts to ensure smooth operation. When supplying parts, a certain amount of parts are often manually fed into the parts feeder, so the time that the parts are inserted into the parts feeder is inevitably long, which may have a negative impact on the type of parts. It had drawbacks such as:

In view of these drawbacks, the present invention is designed to feed an appropriate amount of parts to the parts feeder by connecting a detection device that detects the amount of parts in the parts feeder to a solenoid, and opening and closing the hopper with a lid moved by the solenoid. An example of an embodiment of the present invention will be described below based on the drawings, in order to solve the above-mentioned drawbacks.The device for supplying parts to a parts feeder according to the present invention includes a supply mechanism 1, It consists of a hopper part 2 that sequentially drops the hopper, and a support 3 that supports the supply mechanism 1 and the hopper part 2.

The above-mentioned support column 3 is erected on a mounting base 4, and a cylinder 6 fixed to the lower right end of the base plate 5 is fitted into the upper end of the mounting base 4 so as to be movable up and down, and a bolt 7 screwed into the cylinder 6 is inserted. A plastic circular box 8 with an open top end is fixed on the base plate 5, and a through hole 9.10 is formed in the center of the box 8 and the base plate 5. A hopper 11 whose upper end is in close contact with the box 8 is fitted into the through holes 9 and 10, and a small diameter supply cylinder 12 is integrally projected from the lower end of the hopper 11. A ring 13 made of an elastic material such as
It is fixed in a predetermined position.

Further, at the bottom of the base plate 5, a bracket 1 is attached to the supply tube 12.
The solenoid 16 installed in step 5 is provided,
A right end portion of an arm 19 whose center portion is pivotally supported by a support rod 18 is pivotally attached to the plunger 17 of the solenoid 16, and a discharge port 20 at the lower end of the ring 13 is attached to the left end portion of the arm 19.
A chevron-shaped lid body 21 made of an elastic body such as rubber that can be attached and detached from the discharge port 20 is fixed to the discharge port 20 by the action of the solenoid 16.
In contrast, the lid body 21 is made to be able to be opened and closed freely.

The solenoid 16 acts only when the plunger 17 is sucked to open the lid 21, and when the lid 21 is closed, it is activated by the action of a coil spring 22 that is loosely stretched between the left end of the arm 19 and the bracket 15. There is.

Further, a lower end portion of a swing line 23 made of piano wire or the like is fixed to the lid body 21, the upper end of which extends into the hopper 11.

A power source 24 is connected to a detection device 25 that detects the amount of parts in the parts feeder, and operates the solenoid 16 based on a signal from the detection device 25.

Next, to explain the operation of the feeding device according to the present invention, when the number of parts in the parts feeder decreases and a signal is sent from the detection device 25, the solenoid 16 is energized by the power supply section 24 and the plunger 17 is sucked. , which causes the arm 19 to tilt and the lid 21 to open the discharge port 20.
The parts in the box 8 pass through a hopper 11 and a supply cylinder 12, and are discharged and supplied from a discharge port 20 into a parts feeder mite.

When a predetermined amount of parts is fed into the parts feeder, the detection device 25 de-energizes the solenoid 16, so the arm 19 slowly returns to its original position due to the action of the coil spring 22, and the lid body 21 closes the discharge port 20. This will cause the supply of parts to stop.

When the lid 21 repeats the opening and closing operations in this manner, the swing line 23 fixed to the lid 21 moves from the supply cylinder 12 to the hopper 1.
1, so the parts are attached to the supply tube 12 and the hopper 1.
1 and falls smoothly into the discharge port 20 without clogging.

In addition, by loosening the fastener 14 and moving the ring 13 up and down, the gap between the lower end of the ring 13 and the lid 21 can be freely adjusted, and an appropriate gap can be determined depending on the size of the part and the required supply amount. It can be done.

In short, the present invention provides a hopper 11 on a plywood 5 inserted into a support column 3, and adjusts the vertical position of a ring 13 made of an elastic material such as rubber on a supply tube 12 that integrally projects from the lower end of the hopper 11. Since the ring 13 is inserted freely, the gap between the discharge port 20 at the lower end of the ring 13 and the lid 21 that opens and closes the discharge port 20 can be reduced by moving the ring 13 up and down depending on the size of the supplied parts and the required supply amount. In addition, since the discharge port 20 at the lower end of the ring 13 is operated by the action of the solenoid 16 and is opened and closed by the chevron-shaped lid 21 made of an elastic material such as rubber, parts can be removed by closing the lid 21. Even if it gets caught between the lid 21 and the discharge port 20 at the lower end of the ring 13, it will not damage the parts, and furthermore, due to the shape of the lid 21, no parts will remain on the lid 21, so other Rondo parts will not be damaged. This can prevent accidental mixing of

In addition, since the lid 21 that opens and closes the discharge port 20 of the hopper 11 is attached to an arm 19 that is swing-controlled by a solenoid 16 with a position eccentric to the axis of the discharge port 20 as a fulcrum, the lid 21 and the discharge port 20 can be opened and closed. Rather than opening and closing vertically along the axis, the lid 21 opens and closes obliquely along a circumferential trajectory centered on an eccentric fulcrum. reaches inside the hopper 11 and fixes the lower end of the swing line 23 made of piano wire or the like, so that the swing line 23 does not simply move up and down due to the opening/closing operation of the lid 21, but rather swings back and forth significantly. Hopper 11 every time 21 is opened and closed. This makes it possible to prevent components from clogging within the supply cylinder 12.

Therefore, according to the present invention, it is possible to always automatically feed the appropriate amount of parts to the parts feeder, which helps to save labor, and also reduces the time required to insert parts into the parts feeder, eliminating negative effects on the parts and making the process smoother. Its practical effects, such as being able to operate a parts feeder, are tremendous.
