Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying eyebrow hair to a processing machine such as a hair flocking machine for manufacturing toothbrushes and other brushes.

In general, the hair replenishment in turtle hair machines is performed manually and is inferior.
In this manual operation, when inserting the bundle of hair bound with an elastic rubber band into the supply channel, the worker manually inserts it between the insertion rod and the supply guide and presses it down, taking care not to scatter the eyebrows. Then, gently tighten a rubber band with your fingertips, expand it with both hands, and remove it.Furthermore, while holding the eyebrows so that they do not stand up and fall down, press them from both sides with your fingers to loosen the eyebrows, and then tighten the glans. The method is to remove the close contact between the surrounding hairs by beating them with the palm of your hand, and then set them in the supply guide after forming the shape. This manual work is quite complicated and inefficient, and it is also difficult to use rubber bands. There was an inconvenience that the elasticity of the rubber caused the eyebrows to lose their upright position or cause hairs to scatter around the eyebrows due to poor sampling.

In particular, due to the demand for increasing the productivity of processing machines, there is a tendency for peripheral hair consumption to increase, and there are limits to conventional manual replenishment operations, resulting in relatively high production costs and problems in terms of quality control due to variations in the replenishment status. The present invention aims to accurately eliminate these conventional drawbacks, and automatically performs hair replenishment without manual intervention or using a replenishment cassette, greatly increasing productivity. The object of the present invention is to provide a device that can improve brush quality, reduce manufacturing costs, and simplify quality control of brushes.

The present invention relates to a conveying mechanism that holds the bundle of hair bundled with an elastic ring for binding and delivers it from a supply path to a supply guide of a processing machine such as a hair transplanter, and a conveyance mechanism that holds the bundle of hair bundled with an elastic ring for binding and delivers the bundle of hair to the supply guide of a processing machine such as a hair transplanter. A pusher mechanism that transports the bundle of hair to a predetermined position, a pushing mechanism that pushes the eyebrow group from which the elastic ring has been removed by the pusher mechanism into the processing machine along a supply guide, and an elastic band that binds the hair bundles held by the pusher mechanism. This automatic bristle supply device is characterized by comprising a ring extraction mechanism that hooks and pulls out the ring with a claw piece, and a removal mechanism that detaches the elastic ring removed from the bristle bundle by the extraction mechanism.

An embodiment of the present invention will be described based on the drawings.

At the upstream end of the introduction path 1 whose downstream end is connected to a processing machine such as a flocking machine, an input section 1' is provided continuously on the introduction path surface, and the input section 1'4 is bundled with an elastic ring R. A supply magazine 2 storing hair bundles M in a row is provided at an angle. The carry-in section 1' is provided with a conveyance mechanism A for conveying the hair bundles M, which have been transferred from the lower end opening of the magazine 2 onto the carry-in section 1', onto the introduction path 1 one by one.

An arc-shaped shutter 3'' approximately centered on the rotation axis of the arm plate 3 extends from the extrusion side arm end of the arm plate 3. Its length is such that the opening of the magazine 2 is always closed when the arm plate 3 is operated. The arm plate 3 should have a turning distance or more so as to be closed.

A guide plate ll' for regulating the hair bundle M is provided at an appropriate part of the carry-in section 1' within the rotation range of the arm plate 3, and is formed by the guide plate 1'' and the extrusion side arm. The bare skin part of the hair bundle M is gradually narrowed and the hair bundle M is discharged to a predetermined location ρ in the introduction path l.

The introduction path 1 is provided with a pusher mechanism B that pushes and slides the bristle bundle M discharged to a predetermined position of the introduction path a predetermined distance downstream. The introduction path 1 has side plates 4, 4 provided at appropriate intervals from the bottom plate, and at a predetermined position on the introduction path, the side plates 4, 4 and the front surface of the pusher mechanism B and the rear surface of the push-in/ridge structure described later are connected. The ring R shape of the bristle bundle M to be shaped is formed to be approximately circular or elliptical in a gentle continuous manner on the projection plane.

The bushing mechanism B is equipped with two bushing plates 5, an upper and a lower part, which are continuous between a pair of hands with a concave curved surface 5' and serve as a pressing surface for the hair bundle M. A protruding plate 6 having protruding claw pieces is attached so that a recess can be provided to the stripped hair bundle M along the curved surface 5'. The plate has a shape in which a curved surface 5' is gently continuous with the side plates 4, 4 on the projection plane at a predetermined position in the introduction path.

The upper plate 51 is positioned at a position lower than the height of the ring R of the hair bundle M when it is moved on the introduction path 1, and at a position higher than the side plate 4. The curved surface 5' of the upper plate 51 is further provided with a notch 5'', and the protruding plate 6 is located below this notch 5'' so that when the protruding plate 6 enters the hair bundle M, the ring R is Space upholstery R

．． It is attached to one part via a bracket 7 to form a button mechanism B. When going forward or backward in the introduction path 1, the lower part J of the ring extraction mechanism C, which will be described later, is fixed to the base plate 8 with the extrusion surface facing the turning direction, and when outside the introduction path, it is fixed in the direction of the turning radius. It is rotatably supported by a bracket 7 so as to escape from the lower area of the ring puller section C, and is appropriately provided with swinging means 9 for the hand section.

A ring extraction mechanism C consisting of fixed claws 11, 114 and a movable claw 12 is further attached to the rotating base plate 8 via a plastic fitting 1G, which also serves as a ring removal mechanism.

Fixed claws 11, 11. The movable claw 12 has the upper end of the winter melon fixed to a claw plate 14 connected to the cylinder 13 so that the space tensioning portion R' of the ring R can be moved up and down when the rings are brought into contact with each other. It has approximately the same length. The movable claw 12 is made of a spring material, and its lower end is bent toward the fixed claw 11, 11 and has a bare rubber sheath. The movable claw 12 is bent 12' so that the distance from the fixed claw 11.degree.11 is different.

A claw opening/closing plate 15 is provided which inserts the three claws 11, 11, 12 into three fitting holes provided in the plate and slides vertically along the claws.

That is, regardless of the bending of the movable claw 12, the claw opening/closing plate 15 connected to the cylinder 16 moves up and down while regulating the three claws to a predetermined position on the plate through the predetermined holes. The claws 12 are configured to move their free ends to open or close the lower ends of the three claws.

The bushing mechanism B and the hair bundle M are provided downstream of the introduction path l.
A pushing mechanism is provided for holding the ring R and pushing out the peripheral hair group M' from which the ring R has been removed toward the processing machine.

The push-in mechanism is a pair of push-in plates 1-17 and 17 provided on both sides of the introduction path 1 in the width direction, and can be freely projected into and retracted into the introduction path 1 from the width direction, and can also move forward and backward along the direction of movement of the introduction path 1. It is formed freely.

Each plate 17 has a length approximately half the width of the introduction path 1 as an action part, the downstream side is a plane 17' that becomes the extrusion surface of the eyebrow group M'6D, and the upstream side becomes a clamping surface for the hair bundle M. Said curved surface 5'
The curved surface divided into two in the width direction of the introduction passage 1 has a substantially symmetrical curved surface 17'', and both plates advance simultaneously to form an extrusion surface on the downstream side and a clamping surface on the upstream side.

The base of the plate 17.17 is bent upward and connected to the bracket 18.18I, which forms the bracket 1g.

18 is connected by a transmission mechanism such as a pinion or a rack at 19', and by driving a cylinder 19 connected to one of the brackets 18, advance into and retreat from the introduction path 1 is controlled at the same time. The bracket 1-18.degree. 18 is provided on the rotating base plate 20 so that the plate 17.degree. 17 moves within the introduction path 1 downstream or outside the introduction path 1 downstream over a predetermined range. plate 17.17
must have a flatness at least lower than the ring R of the bristle bundle M and a height that does not collide with the upper plate 51 of the bushing mechanism B. It's like it's going to die.

By the way, the hair bundle M is bundled with a ring R at approximately the middle height. Therefore, in order to set the height of the upper plate 51 and the play 1' 17.17 relative to the hair bundle M to the surrounding hair group to a height that can suppress the surrounding hair more accurately, the introduction path extends over the range transferred by the bushing mechanism B. A space 21 of an appropriate height is provided on one surface.A presser roller 22 rotates while pressing the head of the circumferential hair group M' so that the circumferential hair group M' moves along the slope or step created by the spacer 21.
Placket 18. , 18. This pressing roller 22 is always located at the center of the bracket 18.18, that is, directly above the peripheral bristles group l, regardless of the displacement of the bracket 18.18.
It is centered by a piano wire 23 or the like led out from the rotating board 20.

In the figure, 24 is a rotation axis of the arm plate 3, 25 is a motor capable of forward and reverse rotation, 26 is a transmission mechanism, 27 is a rotation axis of the rotating base plate 8, 28 is a guide rod, and 29 is a rotation axis of the rotating base plate 20. .

Thus, the bristle bundle M bound at the center by the ring R is transferred from the magazine 2 onto the loading section 1' with the peripheral hair standing up. The arm plate 3, which was waiting at the magazine outlet, locks the hair bundle M, rotates, and transfers the hair bundle M to the introduction path 1.
Release inside. The arm plate 3 rotates in the opposite direction and waits again at the magazine outlet.

Next, the bushing plate 5 locks the hair bundle M in the introduction path l and pushes it out and slides downstream. At this time, push play)
17.17 is waiting at a predetermined position on the downstream side of the introduction path 1 by overlapping the protruding ends to form a curved surface 17''.Then, the hair bundle M is pressed against the clamping surface of the pushing plate 17.17, Further, the bushing plate 5 is advanced until the projection plate 6 enters into the eyebrow bundle M and a space stretching portion R' is generated in the ring R.

After that, fixing claw 11. The pawl plate 1-14 is lowered with the lower ends of the movable pawl 11 and the movable pawl 12 open, and the space stretching portion R' of the ring that has spilled out is positioned between the fixed pawls ii and it and the movable pawl 12. The movable claws 12 are closed by the movement of the claw opening/closing plate 15, and with the ring R locked between the three claws, the claw plate 14 is raised to remove the ring R from the hair bundle M.

At this time, if the hair bundle is supported in a state where a corner is formed in the ring R shape, the hair around the corner may fall out and scatter.
Since the hair bundle M is held in a substantially cylindrical or elliptical shape, there is no possibility that the surrounding hair will be disturbed and follow the ring R and be pulled out.

Next, the push plate 17.17 is retracted from the introduction path 1 (
At this time, it is preferable that the bushing plate 5 is advanced simultaneously until the head of the eyebrow group M' merges with the tail and end of the eyebrow group M' supplied previously so that the eyebrow group M' from which the ring R has been removed does not fall. ) Retract the outside of the introduction path l.

Then, instead of the bushing mechanism B, the peripheral hair group M' supplied this time is inserted into the introduction path 1 from the lower part of the upper plate 51 so as to be pressed from behind until the protruding ends overlap, and then it is moved forward on the introduction path 1. Then, the peripheral hair group M' is sent out to the processing machine side on a plane 17' which becomes a skewer surface.

The pusher plate 5, which has relayed the circumferential bristles M' to the pusher plates 17 and 17, returns to the standby position.

The ring R removed by the claw returns to the standby position while being picked up upwards, and after the button plate 5 shakes its head and escapes from the lower area of the ring R, the claw opening/closing plate 16 is moved up and down to remove the ring R. to fall.

Thereafter, the head of the butcher plate 5 is returned to standby for the next operation.

Said loading mechanism A1 Butsusha Isoki B1'l ring extraction mechanism C
1 The movement of the push-in mechanism along the introduction path l to introduction path 1' is shown as being connected to a rotating shaft so that it can freely rotate.
A cylinder may be connected to the base plate of each mechanism provided so that the fixed shaft is swingable, and the cylinder may be moved back and forth. In any case, each mechanism may be provided so as to be able to reciprocate on the introduction path 1sfa and entry path 1' by appropriate known means, or the magazine 2 may be connected directly to the introduction path 1 or may be placed manually.

Further, the transfer action and the clamping action of the pusher/holding mechanism B and the pushing mechanism may be performed by independent mechanisms, and the pushing action D is the advancement and introduction of the clamping surface into the introduction path l. , @1 is divided into two parts to make it easier to retreat, but it is also possible to do so without dividing it, or it can be provided above the introduction path l so as to be movable up and down, so that the hair bundle M can be held.

In the present invention, any configuration may be adopted as long as the hair bundle M can be supported so that no corners are formed in the ring shape, and the ring R can be removed from the hair bundle M in this state. It is preferable to take care so that each mechanism can keep the locking and pressing heights of the eyebrow clasp M to the eyebrow group M' optimally.

Non-invention ζ Therefore, to provide a device that can automatically and accurately transfer and supply only open hair to a processing machine such as a hair transplanter with the ring removed, as long as the open hair bundled with an elastic ring is supplied. It has a practical effect similar to that of fire.
