Description

  The present invention relates to an apparatus for mounting rivets on a rivet holding band, in which a large number of rivets such as blind rivets and nails are successively mounted on a rivet holding band one by one.

For example, a blind rivet in a continuous rivet is attached to a rivet holding band, and the rivet holding band is stored in the continuous rivet so that the blind rivet is driven and caulked on an object. Normally, the user purchases and uses a rivet holding band with a blind rivet, but this is used only once, and the empty rivet holding band is discarded.
Therefore, the present applicant has provided an apparatus capable of continuously mounting rivets on a rivet holding band because it is uneconomical to discard after one use (see Patent Documents 1 and 2).
An apparatus for continuously loading the conventional rivets into the rivet holding band (hereinafter simply referred to as a conventional apparatus) includes a hopper for rivets, a rivet wheel, and a rivet in the hopper that is continuous with the hopper. A feeding path for guiding the rivet wheel to a delivery position, a rotating roll or an alignment feeder for dropping rivets into the feeding path, a rivet regulating member, a rivet pushing member, a rivet wheel and a rotating roll, Drive means for the alignment feeder.
This conventional apparatus is preferable because rivets can be automatically mounted on a rivet holding band, a rivet holding band loaded with rivets can be easily obtained, and a used rivet holding band can be used repeatedly. It is.

While engaging with a pushing member 42 to be pushed into the holding notch 37 and a locking hole 38 provided in the trunk portion 27 of the rivet wheel 15 and equally spaced along the length direction of the rivet holding band 36, And a sprocket 35 for feeding out the rivet holding band 36.

The rivet aligning and supplying apparatus including the hopper 11 and the aligning feeder 12 includes an elevating drive mechanism 13 that drives the aligning feeder 12 to move up and down, and is arranged between the aligning feeder 12 of the hopper 11 and the rivet wheel 15. Is provided with an inclined chute 14 that bridges the rivets 49.
The hopper 11 is formed in a box shape with an open top. The bottom plate of the hopper 11 has an outer portion in the width direction formed on a flat surface 16a, and a central portion formed on an inclined surface 16b, so that the rivets thrown in can naturally gather at the central portion. Further, a slit 17 (see FIG. 3) through which the alignment feeder 12 can be moved up and down is provided at the center of the bottom plate of the hopper 11.

  The alignment feeder 12 is formed in an elongated U-shape when viewed from above, and has an alignment slit 18 for rivets. The alignment slit 18 is formed with a width larger than the shaft portion 49b of the target rivet 49 and smaller than the head 49a. Therefore, as shown in FIG. 3, the head 49a of the rivets 49 is received on the upper surface of the alignment slit 18, and the shaft portion 49b of the rivets 49 is suspended in the alignment slit 18, and is supported substantially vertically by gravity. And are configured to be aligned. Further, the upper surface of the alignment feeder 12 is formed on a slope having a downward slope toward the delivery position with the rivet wheel 15 so that the aligned rivets can be naturally dropped by gravity.

  As shown in FIG. 3, the elevating drive mechanism 13 of the alignment feeder 12 uses a crank mechanism as a mechanism for converting the rotational movement of the motor 19 into the elevating movement. This crank mechanism is attached to the drive shaft 20 of the motor 19 and has a crank arm 22 having a follower 21 at the tip, a long guide groove 23 in the horizontal direction, and one side on the lower end side of the alignment feeder 12. And a transmission arm 24 attached to the section. A follower 21 is engaged in the guide groove 23. In the crank mechanism, when the drive shaft 20 is rotationally driven in the direction of arrow c, the crank arm 22 rotates in the same direction, and the follower 21 moves along the guide groove 23 while pushing up or pulling down the transmission arm 24. For this reason, the alignment feeder 12 can be moved up and down in the direction of the arrow d.

  The inclined chute 14 is provided with a slit 25 having the same width as the alignment slit 18 provided in the alignment feeder 12. This slit 25 is connected to the alignment slit 18 when the alignment feeder 12 is raised to the vicinity of the upper limit position, receives rivets from the alignment slit 18, and is received by the chute 14 having a downward slope similar to that of the alignment feeder 12. It is supplied to the delivery position with the rivet wheel 15 in the posture as it is. Since the chute 14 is composed of a slit 25 having a diameter larger than the shaft portion 49b of the rivet 49 and smaller than the head 49a, the chute 14 falls into the slit 25 received from the alignment feeder 12 even if the chute 14 is inclined. 2 and 4, the head portion is supported on the upper surface of the chute 14 and the shaft portion is suspended in the slit 25, so that the rivets 49 have a gravitational force. It works to maintain a vertical posture at all times. Accordingly, the rivets 49 of the chute 14 are aligned and supplied to the groove 29 of the rivet wheel 15 while maintaining a vertical posture.

On the other hand, the rivet wheel 15 has a wheel shaft 26 at the center. The wheel shaft 26 is arranged so as to be positioned substantially at right angles to the inclined chute 14, and the rivet wheel 15 is attached orthogonally to the top of the shaft 26 and is provided at an inclination corresponding to the inclination of the chute 14. ing. As a result, the rivets 49 that are sent while being aligned in a vertical posture by the chute 14 can be reliably delivered to the groove 29 of the rivet wheel 15.
As shown in FIGS. 2, 4, and 6, the rivet wheel 15 is formed by providing housings 28, 28 at the upper and lower ends of the boss-shaped body portion 27. Rivets locking grooves (holding grooves) 29 are provided at equal intervals on the periphery of each of the housings 28 at positions facing each other.

The wheel shaft 26 is rotatably supported by the bracket 30, and a worm gear 31 is attached to the lower end portion of the wheel shaft 26. A horizontal shaft 32 is rotatably supported by the bracket 30 so as to pass through the bracket 30, and a worm wheel 33 that meshes with the worm gear 31 is attached to a central portion of the horizontal shaft 32.
A handwheel handle 34 is attached to one end of the horizontal shaft 32 protruding from the side portion of the bracket 30. Therefore, the rotation of the handwheel 34 converts the rotation of the horizontal shaft 32 into the horizontal rotation of the rivet wheel 15 around the wheel shaft 26 that is the vertical shaft. Here, a motor may be used instead of the handwheel handle 34. The wheel shaft 26 and the horizontal shaft 32 are supported by bearings (not shown) that facilitate rotation.

  In addition, a sprocket 35 having teeth that are locked in the locking holes 38 of the rivet holding band 36 is provided at the central portion of the outer periphery of the body portion 27 of the rivet wheel 15, and this rivet holding band is rotated by the rotation of the rivet wheel 15. It functions to send out 36. FIG. 12 is a front view showing a part of the rivet holding band 36 in a developed state. The rivet holding band 36 has a plurality of upper and lower tabs 36b, 36c that can be bent in an L shape with respect to the band-like part 36a at both ends (upper and lower ends) of the band-like part 36a. A holding notch 37 is provided at a corresponding position at the end. Further, the belt-like portion 36a is provided with a locking hole 38 for feeding the belt-like portion 36a while being locked to the teeth at intervals of the teeth of the sprocket 35. The locking hole 38 is a hole for sending out a rivet holding band when used in a riveter.

  In the vicinity of the rivet wheel 15, as shown in FIG. 5, a guide post 39 that can be horizontally rotated around a shaft 39 a and a guide post 39 for introducing the rivet holding band 36 between the guide post 39. A guide bracket 40 having a U-shape and a rivet holding band 36 which is provided in the middle of the guide bracket 40 and is expanded as shown in FIG. 12 is replaced with a rivet holding band 36 having a U-shaped cross section as shown in FIG. And a rivet holding band 36 which is provided opposite to the body 27 and is pressed against the body 27 in a region extending from a portion for receiving rivets from the chute 14 to immediately before the pushing member 42 and a rivet wheel. The positioning regulating member 41 that supports and guides the head 49a of the rivets 49 as shown in FIG. A pushing member 42 for pushing the rivets located in the groove 29 of the reel 15 into the holding cutout 37 of the rivet holding band 36, a rivet guide 43 for pushing the received rivets 49 into the groove (holding groove) 29, A holding band removing bracket 44 that faces the outer periphery of the portion 27 as shown in FIGS. 4 and 5 is disposed.

  As shown in FIG. 7, the regulating member 41 is formed with a guide notch 41 a that supports the head 49 a of the rivets 49. This regulating member 41 regulates the position of the rivets 49 and makes the mounting position on the rivet holding band 36 constant. Even if the rivets 49 are stored in the groove 29 of the rivet wheel 15, the rivets 49 may move in the vertical direction in the groove 29 and cause a positional shift. In order to prevent this, as shown in FIG. 7 and FIG. 10, the rivet holding band 36 is positioned between the upper and lower tabs 36b, 36c, and the head 49a of the rivets 49 is locked by the guide notch 41a. The position of the class 49 is held constant.

  The pushing member 42 is a rotating member 46 that rotates about a shaft 45, and the rotating member 46 is used to appropriately attach the rivets 49 to the holding notches 37 of the rivet holding band 36. And a pressing amount adjusting member 47 to be adjusted.

Next, the operation of the apparatus having the above configuration will be described. First, a large number of rivets 49 such as blind rivets and nails are randomly placed in the hopper 11. The rivets 49 gather at the central portion as they descend the slope 16b in the hopper 11. Here, when the motor 19 is driven, the crank arm 22 of the elevating drive mechanism 13 is rotated, and the follower 21 at the tip thereof moves up and down while moving in the guide groove 23 of the transmission arm 24.
For this reason, the alignment feeder 12 to which the transmission arm 24 is attached moves up and down through the slit 17 of the hopper 11 in the direction of arrow d. By this operation, the rivets 49 near the center of the hopper 11 are scooped up by the alignment slit 18. At this time, as shown in FIG. 3, the rivets 49 that have fallen into the alignment slit 18 are supported by the top surface 49a of the rivets 49 on the upper surface of the alignment feeder 12, and the shaft portion 49b is suspended in the slit. Become.

The rivets 49 aligned in this manner slide downward on the inclined upper surface of the alignment feeder 12 due to their own weight, and transfer to the slit 25 of the chute 14. The rivets 49 transferred to the chute 14 are continuously supplied to the delivery position with the rivet wheel 15 as shown in FIGS.
Near the exit of the chute 14, a rivet wheel 15 is approaching. By rotating the handwheel handle 34 provided independently of the motor 19 with the rivet wheel 2, rivets 49 delivered from the chute 14 are stored one by one in the groove 29 of the rivet wheel 15.

  On the other hand, when the rivet holding band 36 in the unfolded state as shown in FIG. 12 is guided and supplied along the guide post 39 and the guide bracket 40, as shown in FIGS. In the state where the rivet wheel 15 is bent in a U-shape as shown in FIG. 7, the upper and lower tabs 36b, 36c are directed outwardly between the upper and lower housings 28, 28 of the rivet wheel 15. Moving. This is schematically shown in FIG.

At this time, since the restricting member 41 extends against the body portion 27 of the rivet wheel 15, the rivet moves between the upper and lower housings 28, 28 of the rivet wheel 15 with the upper and lower tabs 36b, 36c facing outward. As shown in FIG. 7, the holding band 36 moves in such a manner that the regulating member 41 is positioned between the upper and lower tabs 36 b and 36 c so that the band-like portion 36 a is pressed. Accordingly, the rivets 49 housed in the groove 29 of the rivet wheel 15 are restrained in position by the head 49a of the rivets 49 being locked to the guide notch 41a of the restricting member 41 as shown in FIGS. Guided.
Further, since the band-like portion 36 a of the rivet holding band 36 is provided with a locking hole 38, the rivet holding band 36 moves by contacting the band-like portion 36 a with the trunk portion 27 of the rivet wheel 15. The locking hole 38 is locked to each tooth of the sprocket 35. For this reason, the rivet wheel 15 and the rivet holding band 36 are automatically aligned. Therefore, the rotation of the rivet wheel 15 is directly and reliably transmitted to the rivet holding band 36, and no slip occurs between them.

  When the rivet holding band 36 is further moved along with the rotation of the sprocket 35, the rivets 49 on the rivet wheel 15 are guided to the rivet holding band 36 side by the rivet guide 43, and then the rotation in which the rotation amount is set by the pushing member 42. By the member 46, the rivets 49 are pushed into the holding notches 37 of the rivet holding band 36 and attached. Since the pushing member 42 has the pressing amount adjusting member 47, the turning angle of the turning member 46 about the shaft 45 can be adjusted by operating the pushing member 42. By this adjustment, the pressing pressure and the pressing amount of the rivets 49 with respect to the holding notches 37 can be arbitrarily adjusted according to the size and shape of the rivets 49.

The manner in which the rivets 49 at this time are attached to the rivet holding band 36 is shown in FIGS. FIG. 8 is a partial perspective view immediately before the rivets reach the rotating member as the pushing member, and FIG. 9 is a partial perspective view in a state where the rivets are pushed into the rivet holding band by the rotating member as the pushing member. In both cases, the regulating member is omitted. FIG. 10 is a cross-sectional view showing a state where rivets are pushed into a rivet holding band by a rotating member as a pushing member.
As shown in FIGS. 7 and 8, the rivets 49 housed in the grooves 29 and 29 of the rivet wheel 15 and positioned at the entrance of the holding notch 37 of the rivet holding band 36 and regulated by the regulating member 41 are rivet wheels. The rivet holding band 36 moves with the rotation of 15. At this time, as shown in FIGS. 8 to 9, the rivets 49 that have moved to the rotating member 46 as the pushing member 42 are pushed into the holding notch 37 of the rivet holding band 36 by the inclined surface of the rotating member 46. In this way, the rivets 49 are sequentially attached to the rivet holding band 36, and the rivet holding band 36 to which the rivets 49 are attached can be obtained.
