Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component supply device for continuously supplying a component to a work member for assembling a circular shaft component in combination with another component.

[0002]

[Prior art]

 For example, in the case of forming a connecting nail by combining circular shaft-shaped parts such as a nail having a head at one end with a tape at regular intervals, a part supply that continuously conveys and supplies parts to the tape. Equipment is required.

FIG. 1 shows the structure of the above-described component supply device, which includes a parts feeder 1 for keeping the posture of the parts constant, and a rail part 2 arranged at the discharging part of the parts feeder 1 so as to be inclined downward toward the end. A work member 3 arranged at the same end as the rail unit 2 so as to rotate or slide at the terminal end of the rail unit 2, and a work member 3 located between the rail unit 2 and the work member 3 and from the rail unit 2. It is composed of a block 9 that guides to the work piece 3 and a block 8 that surrounds the work member 3 approximately halfway. When parts are randomly placed in the parts feeder 1, the parts are supplied to the rail part 2 in a fixed posture, Is moved to the end side while being held in a suspended state by the head by the two plate-shaped rail bodies 4 and 5 facing each other, and the axis of the component is attached to the outer periphery of the work member 3 via the guide path 10 of the block 9. Hold and store parts Parts are continuously supplied into the recessed groove 6 provided by the rotation of the work member 3.

The parts conveyed in the rotation direction of the work member 3 are combined with the tape at a position opposite to the part supply, for example, to form a connecting nail.

In the above component supply device, it is necessary to surely supply the components to the respective concave grooves 6 of the work member, and it is most important to transfer the components from the rail portion 2 to the work member 3. It will be a part. In addition, as the parts to be supplied to the work members, those with different diameters can be used within the allowable range, but the transition timing of the parts with respect to the diameter change is also an important point.

Conventionally, in a large-scale component supply device operated as an in-plant device, a nozzle for injecting compressed air toward the component is arranged near the end of the rail section to compress the component located at the end of the rail section. Forcibly supplying air into the concave groove of the work member by blowing air.

[0007]

[Problems to be solved by the device]

 However, in small, eg portable, component feeders, the use of compressors, which are heavy and require a large volume, is limited and it is practically impossible to install compressed air injection nozzles.

In a place or condition where the compressor cannot be used, when the component conveyed by the rail is not supplied to the concave groove of the rotating or sliding work member in a timely manner, or the component is weighted against the inclined work member. It is suspended almost vertically, descends the rail part and is supplied to the concave groove of the work member from the lower end side of the part, such as when part of the part is stored in the work member and part remains in the block, etc. The so-called "meshing" phenomenon occurs. As a result, there arises a problem that the end of the block, a part of the gear-shaped work member, or the parts are damaged.

Therefore, the problem of the present invention is that the parts can be reliably supplied from the rail part to the work member without using a compressor, and even if the diameter of the parts changes, the parts can be supplied at the timing, and the "meshing" is caused. It is to provide a component supply device that can avoid the occurrence of problems.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention forms a part passage for guiding a part from the rail part to the work member in a block provided between the end of the rail part and the work member, and the gap between the parts passages. It adopts a configuration that allows adjustment.

In the present invention, the component passage of the block may be formed of two elastic bodies facing each other, and at least one elastic body may be moved to adjust the interval of the component passages.

[0012]

[Action]

 Parts that reach the inside of the parts passage of the block from the end of the rail contact the outer circumference of the work member and stop, and when the groove of the outer circumference faces the rail due to the rotation of the work member, the parts are dented by the weight. It goes into the groove and is stored.

At this time, if the timing at which the part that has been temporarily stopped advances to the concave groove and the rotational speed of the work member do not match, for example, about half of the circular axis of the part advances to the concave groove and the rest passes through the gap and the part passes through. The condition of remaining in the passage occurs. If the work member continues to rotate in this state, the part is sandwiched between the concave groove and the block and is in a meshed state.

However, even in this state, since the component passages of the block are formed by the opposing elastic bodies, the sandwiched circular axis is softly held by the elastic body, and further, due to the restoring force of the elastic body. It is pushed into the groove.

Further, the component passage of the block changes the interval according to the diameter of the component, and finely adjusts the component supply timing to the concave groove of the work member.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the component supply device comprises a parts feeder 1, a rail portion 2, a work member 3 and blocks 8 and 9. As shown in FIG. The circular shaft-shaped component A is held by the plate-shaped rail bodies 4 and 5 in a suspended state at the head portion, and is moved by a downward inclination toward the end.

The work member 3 is formed in a gear shape in which a groove 6 and a protrusion 7 in which the shaft portion of the component A is housed are continuous in a circular shape, and the work member 3 has an inclination angle similar to that of the rail portion 2. It is arranged in front of the end portion of 2, and is given a rotation as shown by an arrow in FIG.

A block 9 is arranged between the work member 3 and the end of the rail portion 2. The block 9 is an extension of the rail portion 2 and has a component passage having an inclination angle equal to that of the rail 2. The part A, which has formed 10 and reaches the end of the rail portion 2, passes through the part passage 10 of the block 9 and is held by the work member 3.

The block 8 located on the downstream side of the rail member 2 in the rotation direction of the work member 3 encloses a substantially half circumference of the outer periphery of the work member 3 and works the part A supplied in the groove 6 as a work piece. It also serves to hold the member 3 along the rotation direction so as not to come off.

In the block 9 located between the rail portion 2 and the work member 3, the surface facing the work member 3 is an arc-shaped surface extending along the outer periphery of the work member 3, and the arc-shaped surface and the surface facing the rail portion 2 are A kerf 11 having a width approximately equal to the outer width of the rail portion 2 and longer than the part A is formed in an inclined shape in the same direction as the rail portion 2 from below the upper surface between the rails 2. A pair of elastic bodies 12 and 13 are mounted so as to face each other between the opposing surfaces of the both sides, and the component passage 10 is formed by the opposing surfaces of the elastic bodies 12 and 13.

The elastic body 12 located on the downstream side with respect to the rotation direction of the work member 3 is formed into an L-shaped plane by the elastic piece 14 located in the cut groove 11 and the mounting piece 15 overlapping the outer surface of the block 9. The mounting piece 15 is formed in the upper and lower sides of the mounting piece 15 in the lateral direction, and the mounting piece 15 is fixed to the block 9 by the bolts 18 screwed from the long hole 16 to the block 9 via the holding plate 17. There is.

As shown in FIG. 4, the elastic body 12 is fixed to the block 9 so that a gap 19 is formed between the elastic piece 14 and the side surface of the cut groove 11 so that the elastic piece 14 has elasticity. I am

The elastic body 13 located on the upstream side in the rotation direction of the work member 3 is formed in a plane L shape by the elastic piece 20 located in the cut groove 11 and the mounting piece 21 overlapping the outer surface of the block 9. , The elastic body 13 is fixed to the block 9 by screwing the bolts 24 inserted through the holding plate 23 into the lateral long holes 22 provided at the top and bottom of the mounting piece 21 into the screw holes 25 of the block 9. It has become.

The elongated plate 26 provided at the rear end of the mounting piece 21 is provided with a vertically elongated hole 27, and an adjusting bolt 29 is screwed into a screw hole 28 provided on the side surface of the block 9, The head 30 of the bolt 29 is fitted in the elongated hole 27.

With the bolt 29 loosened, the elastic body 13 becomes movable along the elongated hole 22, and the adjusting bolt 29 moves in and out in parallel with this, and is connected by the head 30 and the elongated hole 27. The adjusting bolt 29 and the elastic body 13 move together as the bolt 29 moves back and forth.

In the elastic bodies 12 and 13, the part passages 10 are formed between the elastic pieces 14 and 20 facing each other in the cut groove 11, and the interval between the part passages 10 is freely adjusted by operating the adjusting bolt 29. The elastic piece 20 of the elastic body 13 has elasticity due to the gap 31 generated between the elastic piece 20 and the side wall of the cut groove 11.

The component supply device of the present invention has the above-mentioned configuration, and the circular shaft-shaped component A is discharged from the supply source such as the part feeder 1 by electromagnetic vibration or the like, and the rail inclined downward due to the weight of the component itself. It is conveyed via the section 2.

In the component A conveyed from the end of the rail portion 2 into the component passage 10 of the block 9, the work member 3 rotates in the direction of the arrow shown in FIG. When it comes, the weight of the component A advances the component A into the groove 6 and is accommodated therein.

At this time, if the timing at which the part A, which has been temporarily stopped, advances to the concave groove 6 and the rotation speed of the work member 3 do not match, for example, about half of the circular axis of the part A has advanced to the concave groove 6 and remains unremoved. A state occurs where the material remains in the component passage 10 of the block 9 through the gap. When the work member 3 continues to rotate in this state, the parts are sandwiched between the concave groove 6 and the terminal end of the block 8 and brought into a meshed state.

However, even in this state, the elastic piece 14 of the elastic body 12 positioned in the rotation advancing direction of the work member 3 softly holds the circular axis sandwiched by the component A, and the elastic piece Due to the restoring force generated by the bending of the circular shaft 14, the circular shaft is pushed into the concave groove 6, and the occurrence of inconvenience due to the meshing can be prevented.

By the way, the interval between the facing surfaces of the rail portion 2 is set to the maximum diameter within the range that can be transferred by the work member 3, and even if the diameter of the component changes within the range, the transportation of the component is not hindered. You can do it.

However, in supplying components from the component passage of the block 9 to the concave groove 6 of the work member 3, the positional relationship between the posture of the component A held in the passage 10 and the concave portion 6 of the work member 3 is extremely important. Therefore, when a small-diameter component is supplied with the component passage 10 set to the maximum interval, the posture of the component becomes unstable with respect to the rotation direction of the work member 3, which hinders the migration of the component to the concave groove 6. Occurs.

Therefore, the interval between the component passages 10 of the block 9 is set so as to match the diameter of the component A by the movement of the elastic body 13 caused by the rotatable adjustment bolt 29.

In this way, when the distance between the component passages 10 is adjusted to the diameter of the component A, the posture of the component A held in the passage 10 and the concave groove 6 of the work member 3 are aligned, The component A can be reliably supplied to the concave groove 6 of the work member 3.

[0036]

[Effect of device]

 As described above, according to the present invention, the component passage is provided in the block arranged between the end of the rail portion and the work member, and the distance between the component passages can be adjusted. By adjusting in accordance with the above, it is possible to stabilize the posture of the component in the component passage, and it is possible to always stably supply the component to the work member even if the diameter of the component changes.

Further, since the component passage is formed of the elastic body, the meshing of the circular shaft-shaped components generated between the block and the work member can be released by the elastic body, and the disadvantage caused by the meshing can be eliminated.
