Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for automatically supplying a ball for processing and producing a ball-incorporated member that serves as the nib of a ballpoint pen.

[Prior art] Generally, when attaching or attaching an accessory to a workpiece, the timing of supplying the accessory and the accuracy of the work determine the quality of the finished product. It is known to provide a structure in which balls are supplied to the tube material to caulk it.

[The problem that the idea aims to solve]

However, the balls of ballpoint pens are small parts that roll easily, making them difficult to handle. There is a risk of all of the liquid being released, and it is necessary to safely feed the liquid one by one at all times, which is inconvenient because the feeding mechanism and control mechanism are complicated and expensive.

In order to improve these conventional problems, the present invention is a simple and easy-to-configure safe and accurate device that feeds balls to the pipe material of the workpiece without erroneous operation, and does not feed balls when there is no pipe material to feed the balls. The purpose is to provide it in an inexpensive format.

[Means to solve the problem]

The present invention has a movable base 1 which is disposed so as to be able to approach and separate from a chucked pipe M with one end open, and a hopper 2 in which a ball can be accommodated on the movable base 1. The open end 4 of the ball outlet path 3 is arranged facing the open end of the tube M, and the movable shutter 5 for opening and closing the open end 4 is biased by a spring member 6 to move the movable base 1. At the same time, the ball remaining in the ball outlet path 3 is received on the movable shutter 5, and as the movable base 1 moves forward, the edge of the movable shutter 5 is brought into contact with the circumferential side of the tube M, and the spring member 6
This is a ball supply device characterized in that it is configured to compress the ball outlet passage 3 so that the open end 4 of the ball outlet path 3 communicates with the open end of the tube member M.

〔Example〕

An example of the present invention will be explained using examples of FIGS. 1 to 5.
The movable base 1 includes a member 1 ₁ having an inverted U-shaped cross section, a hopper mounting portion 1 ₂ having an extended top plate portion of the member 1 ₁ ,
Consisting of a bottom plate member ₁₃ , a spring receiving member ₁₄ fitted into a space surrounded by the inverted U-shaped cross-sectional member ₁₁ and the bottom plate member ₁₃ , and a frame-shaped movable shutter 5,
The hopper mounting portion ₁₂ is equipped with a hopper 2 that accommodates balls, and the hopper 2 has an open end 4 through which a lead-out passage 3 for accommodating the balls in a line is passed through, and this open end 4 is movable. It abuts on the shutter 5 and is closed by the movable shutter 5 except when balls are being supplied.

That is, the movable shutter 5 is arranged such that the spring receiving member ₁₄ is positioned in the hollow part of its frame, and the upper surface of the movable shutter 5 and the lower surface of the hopper mounting portion ₁₂ are slidably inserted in contact with each other. A spring member 6 is disposed between the spring receiving member ₁₄ and is biased to close the open end 4.

The top of the inverted U-shaped member ₁₁ is connected to the end of an operating rod 8, and the movable base 1 slides on the fixed base 10 and moves forward and backward by horizontal reciprocation of the operating rod 8. .

The fixed base 10 is provided with a convex portion 10 ₁ , and the bottom surface of the convex portion 10 ₁ abuts against a positioning member, such as a bolt 7 , protruding from the base so that the height can be adjusted as appropriate. installed. A pair of guide members 18 for guiding the sliding movement of the movable base 1 are protruded from the upper surface of the fixed base 10 so as to sandwich the movable base 1 therebetween.

The operating rod 8 is supported by stays 9 and 11, and is connected via a lever 13 to a drive rod 12 which is moved up and down by a cam (not shown), and the lever 13 converts the up and down movement of the drive rod 12 into horizontal movement. The power is then transmitted to the operating rod 8.

That is, both ends of the lever 13 are connected to the rods 12, 8 through slidable ring parts 13', 13'', respectively, and the ring parts 13'' are connected to the collars 21, 21' fixed to the operating rod 8. The ring portion 13' is biased in the direction of the collar 21 by a spring 15 between the two, and a spring 14 is disposed between the ring portion 13' and the collar 19 fixed to the drive rod 12, and a locking nut adjustably provided at the end of the rod. 20 side, and is designed to buffer and transmit the vertical movement of the drive rod 12.

In the figure, 16 is an adjustable stopper for regulating the movement of the operating rod 8 in one direction, and 17 is a ball toucher for confirming the supply of balls to the tube M. The contact height of the ball above the path of the tube M after receiving the ball is It is being deployed.

In addition, the sliding surfaces of the hopper mounting part ₁₂ and the movable shutter 5 and the sliding surfaces of the movable base 1 and the fixed base 10 are processed to have smooth surfaces or have gaps formed to enable smooth sliding. It can also be formed.

[Effect]

As a result, the ball can be accurately fed between the receiving hole at the open end of the pipe M, which is chucked with the receiving hole for one ball open at the top, and the open end 4 of the hopper 2, and the ball can be fed smoothly after being fed. The ball supply device and the tube material M are arranged at a height position separated by a distance d that allows for backward movement. When the movable base 1 moves and the tube M waits to receive the ball at a position where the two communicate with each other, the synchronized drive rod 12 is lowered, the lever 13 is rotated by the locking nut 20, and the operating rod is rotated. 8 collar 21' with spring 1
5, the operating rod 8 moves forward, moving the movable base 1 onto the fixed base 10 and moving the hopper 2 forward, but this movement
6 and the stay 11 are in contact with each other, the hopper 2
The opening end 4 of the ball outlet path 3 and the receiving hole of the tube M are set to communicate with each other.

When the movable shutter 5 comes into contact with the tube M while the movable base is moving forward, the movable shutter 5 is held stopped with respect to the tube M. When the movable base 1 moves further forward (toward the right in Fig. 1), the spring member 6 is compressed and the movable shutter 5 remains in the stopped position, and the open end 4 of the hopper 2 communicates with the ball receiving hole of the tube M to drop one ball. (Figure 1A). Next, when the movable base 1 begins to retreat, the movable shutter 5 is returned by the spring member 6 to a position where the movable shutter 5 closes the opening end 4, thereby preventing the ball from falling.
When a further backward movement is performed, the movable shutter 5 also separates from the pipe M and waits until the next movement (Fig. 1).
The ball inside Botupa 2 will not fall to the outside.

In the embodiment described above, the operating rod 8 is moved forward and backward by the drive rod 12 in order to be synchronized with other devices, but a horizontal drive section for the operating rod 8 may also be provided directly.

[Effect of idea]

In the present invention, the open end of the ball guideway formed in the hopper is disposed facing the open end of the pipe material, and a movable shutter for opening and closing the open end is biased by a spring member to create a movable base. Along with preparing,
The ball remaining in the ball outlet path is received on the movable shutter, and as the movable base moves forward, the edge of the movable shutter contacts the circumferential side of the tube, compresses the spring member, and closes the open end to the open end of the tube. This is an efficient feeding device that efficiently and accurately supplies extremely fine balls that roll easily to the pipe material that is being processed, and that no balls leak outside and become wasted. In addition, the ball can be fed to the workpiece without erroneous operation, and the ball will not be fed if there is no workpiece to feed the ball.It has a great practical effect and has a high degree of safety. It is simple and easy to maintain and maintain, and the operating efficiency can be greatly increased through continuous operation.
