2 and 3, the stud feeder 200 includes a stud feeder 210, a stud aligner 220, a stud feeder 230, a controller 240, and a warning device 250. Here, the warning means 250 may not be used according to the embodiment.

The stud feeder 210 transmits the stored stud to the stud aligner 220 according to an instruction from the controller 240. Since it is common for an operator to directly insert the stud into the stud feeder 210, it is preferable that the outer body of the stud feeder 210 is made of a transparent or semitransparent material and the presence or absence of the stud is visually confirmed.

As another embodiment, it is also possible to include a sensor (not shown) for notifying the controller 240 whether the stud exists by using sensing means for sensing the presence and amount of the stud stored therein. At this time, the controller 240 may activate the warning means 250 when it is determined that the stud is not stored in the stud feeder 210 or the stored amount of the stud is insufficient. Here, the warning means 250 informs the operator in the vicinity of the stud feeder 200 that the amount of the stud stored in the stud feeder 210 is insufficient for the subsequent work, .

The stud aligning unit 220 aligns a plurality of studs fed from the stud feeder 210 in a predetermined state and transfers the aligned plurality of studs to the stud feeder 230. The stud transfer unit 230 transfers the stud transferred from the stud aligning unit 220 to the outside at predetermined time intervals. The controller 240 controls the operations of the stud feeder 210, the stud aligner 220, and the stud feeder 230.

The studs used in the present invention are formed at one end and are formed at the head part and the opposite end semi-permanently joined to the object and have a constant thickness and length. The cross-sectional area of the head part is larger than the cross- And is shown in Fig. 1B.

4, the stud feeder 210 includes a chamber body 410, a first conveying unit 420, a plate 430, a second conveying unit 440, a third conveying unit 445, (450).

The chamber body 410 is formed in a cylindrical shape and has a space for storing the inserted stud therein. The lower portion of the chamber body 410 has a feed passage 411 serving as a passage through which the studs stored in the chamber 410 move to the outside of the chamber body 410, Respectively.

The first conveying means 420 located at the upper portion of the plate 430 includes a first body 421 having a conical shape with a central portion projecting upwardly, a second body 421 disposed at an inner central portion of the lower portion of the first body 421, (Not shown) into which a rotary shaft (not shown) rotating at a predetermined angle is inserted according to an instruction of the user and a rolling prevention groove 422 provided on an inclined side of the upper portion of the first body 421. Preferably, the anti-rolling groove 422 is formed as a semicircular groove that is elongated in the lateral direction inclined at the center of the body 421.

As shown in FIG. 1B, a stud having a head portion has a property of being rotated without moving in a straight line when receiving a force from the outside or moving along an inclined surface. Because of this characteristic, the inclined plane in the planar state causes the stud to come in contact with the side wall, or to stop the movement while the stud having different rotational direction is entangled. The first body 421 having a conical shape does not have a wall surface having a flat inclined surface and provides a structure in which the stud naturally descends. The anti-rolling groove 422 provided on the inclined side of the upper portion of the first body 421 is formed in such a manner that when the first body 421 having a conical shape is rotated, the stud is rotated in place along the surface of the first body 421 .

The second conveying unit 440 moves the upper studs to the stud aligning unit 220 through the blocking wall 450 while moving up and down according to an instruction from the control unit 240. The vertical movement of the second transfer means 440 can be realized in various ways. For example, the vertical movement of the second transfer means 440 may be performed by rotating the bar 440 up and down at a predetermined angle, 2 conveying means 440. [0052] As shown in FIG. The control unit 240 controls the vertical movement of the bar and the rotation of the shaft. The basic position and the transfer position of the second transfer means 440 can be determined according to the height of the blocking wall 450 and the amount of the studs that cross the blocking wall 450 in one up-and-down motion.

The upper surface of the second conveying means 440 is formed to be inclined downward from the surface contacting the plate 430 toward the blocking wall 450 so that the stud located at the upper portion of the second conveying means 420 is blocked Will be biased towards wall 450. In order to prevent a space from being formed between the second conveying unit 440 and the plate 430 moved upward when the second conveying unit 440 moves upward so that the studs remaining on the plate 430 do not move, 2 The shape of the transfer means 440 should be determined.

The third conveying means 445 provided between the plate 430 and the first conveying means 420 moves horizontally and conveys the studs, which are gathered in the exposed plate 430, to the upper portion of the second conveying means 440 .

5B is a view illustrating a process of transferring the stud transferred from the chamber body to the upper portion of the plate and the second transfer means while the first transfer means rotates, FIG. 56D illustrates a process of transferring the stud located on the upper portion of the second conveying means to the stud aligning portion while moving the second conveying means upward, FIG. 56D shows a process of conveying the second conveying means Describing each new stud in the upper part of the means.

Referring to FIG. 5A, an operator can prepare for operation or maintain operation of the stud conveying apparatus 200 by visually inserting the stud into the chamber body 410 in accordance with a warning of the warning means 250 or the like.

Referring to FIG. 5B, it can be seen that the studs stored in the chamber body 410 are located above the first transfer means 420. At this time, when the first conveying means 420 rotates by a predetermined angle, the stud located on the upper surface of the first conveying means 420 is moved to the edge of the first conveying means 420 by the centrifugal force of the first conveying means 420 And the stud will be moved to the transfer passage 411, which is an open portion of the surface of the chamber body 410. It is a matter of course that the open conveyance passage 411 should be in the direction in which the second conveyance means 440 is installed. The open area of the transfer path 411 may be determined according to the amount of the stud to be transferred.

5C, the second conveying unit 440 moves up and down to the lowest position, the basic position and the conveying position, and the stud located on the upper surface of the second conveying unit 440 moves beyond the blocking wall 450 To be transferred to the stud alignment unit 220. FIG. 5B shows a state in which the second conveying means 440 is in the basic position, and FIG. 5C shows a state in which the second conveying means 440 is in the conveying position.

When the second conveying means 440 is moved from the basic position to the conveying position, the stud located on the upper surface of the second conveying means 440 is transferred to the stud aligning portion 220 beyond the blocking wall 450, The state shown in FIG. 5C indicates that the second conveying means 440 is in the conveying position.

5C, it can be easily understood that even when the stud passes over the blocking wall 450, the inclination of the upper surface of the second conveying means 440 plays a role.

Referring to FIG. 5D, the stud disposed on the upper surface of the second conveying unit 440 is transferred to the stud aligning unit 220 through the process of FIG. 5C, and then moved to the basic position. At this time, the third conveying means 445 provided between the plate 430 and the first conveying means 420 moves horizontally (leftward), and the studs, which are gathered in the exposed plate 430, are conveyed by the second conveying means 440 The stud remaining on the plate 430 is diffused to the upper surface of the second transfer means 440 and waits for the transfer to the stud alignment unit 220.
