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. It is composed of the work member 3 arranged at the same inclination as the rail part 2 so as to rotate or slide on the terminal end of the rail part 2, and when the parts are put into the random with respect to the parts feeder 1, the parts have a fixed posture. Is supplied to the rail section 2 by the two parts, and the parts are held by the two plate-shaped rail bodies 4 and 5 facing each other while being suspended by the head and moved to the end side, and the shaft part of the parts is held on the outer periphery of the work member 3. The components are continuously supplied into the recessed groove 6 provided so as to be housed by the rotation of the work member 3.

The parts conveyed in the rotation direction of the work member 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.

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 weight of the component increases with respect to the inclined work member. When a part of a part is accommodated in the work member and part is left on the rail part, such as being suspended almost vertically, descending the rail part and being supplied from the lower end side of the part to the concave groove of the work member first. The so-called "meshing" phenomenon occurs. As a result, there arises a problem that the end of the rail portion or a part of the gear-shaped work member is damaged or parts are damaged.

Therefore, an object of the present invention is to provide a component supply device capable of surely supplying a component from a rail portion to a work member without using a compressor and avoiding a problem due to “meshing”. is there.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a rail portion by two plate-shaped rail bodies facing each other, and at least one end of the rail body or a plate-shaped elastic body on a block constituting the end. Is adopted.

[0011]

[Action]

 The parts that reach the end of the rail contact the outer circumference of the work member and stop, and when the work member rotates and the groove on the outer circumference faces the rail, the part moves into the groove due to its weight and is stored. .

[0012] At this time, if the timing at which the part that has been temporarily stopped moves to the concave groove and the rotation speed of the work member do not match, for example, about half of the circular axis of the part moves to the concave groove and the rest goes through the gap and the rail passes. The state that it remains at the end of the section occurs. If the work member continues to rotate in this state, the part is sandwiched between the concave groove and the end of the rail part and is in a meshed state.

However, even in this state, since the elastic body is provided at the end of one rail body positioned in the traveling direction of the work member, the sandwiched circular shaft is softly held by the elastic body, Furthermore, it is pushed into the concave groove by the restoring force of the elastic body.

[0014]

【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 part feeder 1, a rail portion 2 and a work member 3. As shown in FIG. 2, the rail portion 2 has two plate-shaped rails facing each other. The body 4 and 5 hold the circular shaft-shaped component A in a suspended state at the head portion and move it by a downward inclination toward the end.

The work member 3 is formed in a gear shape in which a groove 6 and a projection 7 in which the shaft portion of the part 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.

Between the work member 3 and the end of the rail portion 2, a pair of blocks 8 and 9 which are extensions of the rail portion 2 are arranged at an inclination angle equal to that of the rail portion 2. The component A that has reached the end of the above-mentioned section passes between the facing surfaces of the blocks 8 and 9 and is held by the work member 3.

One block 8 located on the downstream side in the rotation direction of the work member 3 with respect to the rail member 2 surrounds a substantially half circumference of the outer circumference of the work member 3 and is supplied to the groove A in the part A. Is also held along the rotation direction of the work member 3 so as not to come off.

The plate-shaped elastic body 10 is attached to the surface of one of the blocks 8 located downstream of the work member 3 in the rotational direction so as to face the mating block 9 and guide the component A. It is attached.

The elastic body 10 has elasticity that bends in the rotation direction of the work member 3.

The first example of the elastic body 10 shown in FIG. 2 and FIG. 3A is a plane L including a mounting portion 12 having a screw hole 11 and a spring plate portion 13 using a metal plate or a synthetic resin plate. The mounting portion 12 is formed in a letter shape, the mounting portion 12 is fixed to the block 8 with a screw 14, and a gap 15 that allows the spring plate portion 13 to bend is formed between the spring plate portion 13 and the end surface of the block 8.

A second example of the elastic body 10 shown in FIG. 3B is the same as the first example except that the spring plate portion 13 is divided into a plurality of slits 16 and the meshing of the parts is made flexible according to the meshing parts. It is intended to be softly received.

A third example of the elastic body 10 shown in FIG. 3C is the same as the second example, except that the tip of the spring plate portion 13 has a central portion slightly protruding from the upper and lower ends.

In a fourth example of the elastic body 10 shown in FIG. 3D, a plate 17 made of a metal plate or a synthetic resin plate is attached to the end surface of the block 8 via an elastic member 18 such as a spring. It has a structure for mounting.

The fifth example of the elastic body 10 shown in FIG. 3 (E) is one in which the plate 17 of the fourth example is divided into upper and lower parts, and each is attached to the block 8 by elastic members 18. is there .

A sixth example of the elastic body 10 shown in FIG. 3 (F) is formed into a prismatic block shape using an elastic material such as rubber or synthetic resin, and is attached to the end surface of the block 8.

Although each of the above examples of the elastic body 10 is attached to the end of the block 8, the elastic body 10 is directly attached to the end of the rail body 4 located on the downstream side in the rotation direction of the work member 3 in the rail portion 2. Alternatively, this may be exposed to the outer circumference of the work member 3.

Further, although the elastic body 10 is provided at the end of the one rail body 4 in the illustrated case, the elastic body 10 may be provided at the end of both rail bodies 4 and 5 so as to face each other. In this case, the work member 3 is used. The elastic body located on the upstream side in the rotation direction serves as a safety measure when the work member 3 is reversed.

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.

The part A conveyed between the blocks 8 and 7 from the end of the rail part 2 rotates in the direction of the arrow shown in FIG. Due to the weight, the component advances into the groove 6 and is accommodated.

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, approximately half of the circular axis of the part A advances to the concave groove 6 and remains unremoved. A state occurs in which the blocks 8 and 9 remain through the gap. If the work member 3 continues to rotate as it is, the parts are sandwiched between the concave groove 6 and the terminal end of the block 8 to be in a meshed state.

However, even in this state, the elastic body 10 positioned in the rotation advancing direction of the work member 3 softly holds the circular axis between which the component A is sandwiched, and is further caused by the bending of the elastic body 10. Due to the restoring force, the circular shaft is pushed into the concave groove 6, and the occurrence of inconvenience due to meshing can be prevented.

By providing the elastic body so that it can be replaced, even if the end portion is worn, it is not necessary to replace the entire rail portion 2 or the blocks 8 and 9 at the end, and the elastic body can be replaced. Supply can be continued with only 10 replacements.

[0034]

[Effect of device]

 As described above, according to the present invention, since the plate-shaped elastic body is provided on one of the ends of the rail body or the block forming the end of the rail body, the circular shaft-shaped part generated between the rail end and the work member is The meshing can be released by the elastic body, and the inconvenience caused by the meshing can be eliminated.
