For many years, fastener dispensing devices such as that shown in US Pat. No. 3,103,666 have been sold and widely used. Although such a device is satisfactory to a certain extent and has a certain degree of reliability, there is a demand for a device that is even more reliable and durable, that is, a device that is extremely unlikely to jam.

SUMMARY OF THE INVENTION A first object of the present invention is to provide an improved apparatus which is constructed so that the next fastener is not fed until one operation has been completely completed. This prevents the device from jamming and dramatically improves the reliability of the device.

Another object of the present invention is to provide an apparatus that includes a new and improved rack drive arrangement or slide drive for moving an ejector that forces a clasp through a needle. It is constructed so that there are no recesses that could collect or collect lint or other foreign matter that could ultimately lead to malfunction of the device.

Further objects and effects of the present invention will become clear from the following description. Therefore, the present invention has a characteristic structure, combination of elements, and arrangement of each component as exemplified in the embodiments described below.

The present invention and its embodiments will be described in detail below with reference to the drawings.

Figures 26 and 27 show an example of a fastener suitable for being dispensed by the apparatus of the present invention.

The clasp, indicated generally by the reference numeral 30, is formed by a filament having a filament 31 and heads 32, 33 at each end thereof. (This arrangement is well known in the above-mentioned U.S. patent, and its details will be omitted.) In order to connect the fastener 30 to the support 34, the support has a connecting member 3.
5 is provided. When dispensing the fastener 30 through the hollow needle, the fastener is separated from the support by cutting this connecting member, as described below.

Push the clasp into the needle slot 45 (Figure 28),
Alternatively, for feeding, the handle 42 has teeth 49a and 50 along the top surface, respectively, as shown in FIG. 4.6.
It is operatively connected via a member 48 to a gear system consisting of a pair of sector-shaped gears 49 and 50 having &.

Member 4B is pivotally attached to the gear at 51, as shown in FIG.

Gears 49 and 50 are also pivotally connected to the body of the apparatus, as shown in more detail in FIG.

The slide, designated 60 (see especially Figures 4.6.7.8), slides through guide slots 59.62 (Figure 6) formed within each of the body halves 40a, 40b. It is arranged to slide back and forth. The sliding body 60 has a gear 49
．． A plurality of holes 60a (FIG. 8) are provided which are shaped to receive 50 teeth 49a, 50a. This hole extends from the bottom surface 60b (FIG. 9) to the top surface 60c of the sliding body 60.
As shown in FIG. 8, it is formed in two rows so as to receive the teeth of gears 49 and 50. In this way, lint or other foreign matter can be removed by the teeth from the hole 60a.
Since the sliding body and the gear are pushed out from each other, the meshing operation between the sliding body and the gear is not hindered. As the gears rock back and forth,
The sliding body 60 moves back and forth.

The sliding body 60 also has holes, 60d and grooves 60e (No. 8.1

Thus, when the handle 42 is rotated, i.e. rotated closed towards the body and then released;
The τ handle is returned from the main body to the position shown in FIG. 4 by the return device TO.

The device also includes an indexing mechanism 80 (FIG. 4) for positioning one clasp at a time at a position behind the pattern needle for dispensing the clasps through the needle and into the ejector.

This indexing mechanism 80 has an indexing wheel (indexing gear) 81 rotatably supported by a shaft 82 (FIG. 14), and the shaft 82 is supported by a hole 83 in the main body. .

The indexing wheel is a shelf section 40C (
14) and the cover plate 90. Since there is a gap between the indexing wheel 81, the cover plate 90, and the shelf portion 40C, the indexing wheel 81 can rotate freely.

The indexing wheel 81 has a plurality of teeth 81a (FIG. 15) provided along its circumferential surface, and these teeth engage with and support the connecting member 35 between the fastener 30 and the support 34. It is adapted to move the body 34 and the clasp downwardly. The indexing wheel is rotated counterclockwise by a pawl 84 (Figs. 15.16.20-22). This claw 84 has a slot 84a (FIG. 16) formed therein, and is swingably supported by a shaft 82 as shown in FIG. 14. The pawl 84 is pivotally connected at 86 to an extension (link) 85 provided to the pattern, as will be explained in more detail below with respect to FIGS.
It is designed to swing back and forth around the

As shown in FIG. 16, the pawl 84 has a pointed tip 84 so as to engage one of the teeth of the indexing wheel and rotate it.
84b. The end portion 84b of the pawl preferably has a bend at a position 84d, as shown in FIG. ). The other portion is spaced apart from the cover plate 90 (placed on a different plane from the indexing wheel), so that the pawl slot 84a portion can swing freely relative to both the indexing wheel and the cover plate 90. It has been made possible. Therefore, the tip 84e of the pawl is located above the tooth 81a in substantially the same plane as the indexing wheel.

In order to prevent unnecessary rotation of the indexing wheel when the pawl 84 is swung clockwise and counterclockwise as described above, the cover plate 90 has a projection, that is, an articulating element 91g. 91 (No. 15.17.
Figure 19). The articulation element 91a is located in the space 92 (FIG. 19) between the teeth 81a to prevent unnecessary rotation of the indexing wheel. The articulating element 91a only slides relative to the side of the tooth 81a when a sufficient rotational force is applied to the indexing wheel, for example by the action of the pawl 84, thus ensuring control of the fastening into the device. can be done.

Next, with particular reference to FIGS. 4.20 to 22, the claw 84
The mechanism for swinging back and forth will be explained. In the illustrated embodiment, a link (extension part) 85 is provided that is supported so as to be able to swing back and forth, and the link 85 has a groove 85d that defines two engaging parts 85a and 85b that are spaced apart from each other. CH3I diagram). These retaining portions 85a and 85b are configured such that when the sliding body 60 is swung back and forth, the protrusions 60f extending downward from the sliding body 60 engage with them alternately. (Extension part) 85 swings back and forth to swing the pawl 84 and drive the indexing wheel. The rear end of the link (extension) 85 is connected to a member 95 located within a cavity 96 (see Figure 4.7) formed in the main body.
This member 95 is supported by a spring 9
7 is elastically biased towards the syringe (extension) 85. The upward movement of the link (extension) 85 is restrained by a protrusion 98 extending from the main body (Fig. 4.7), and the movement of the link (extension) 85 to one side is restrained. It is restricted by a pin 99 connected to the body (see FIG. 7). The protrusion 98 can also act as a rear stop for the retaining part 85b if desired (alternative configurations of the retaining part 85b and the protruding part 98 are discussed in FIG. 37 and in the description below). ).

The link (extension portion) 85 also includes the links shown in FIGS.
As shown in the figures, a laterally extending protrusion 85c is provided, which is coupled to a release control member 10 (1 (Figs. 23-25 and Fig. 1) having a hole 100a, i.e. , the protrusion 85c enters the hole 100a and is fixed by the chain hole.The member 100 is provided with a finger-like protrusion 100b, which passes through the window 101 formed in the main body. (See Fig. 1).Therefore, when the protrusion 100b is pressed downward and sideways (to the right in Fig. 1) and the link (extension) 85 is moved to the position shown in Fig. 22, the claw 84 is disengaged from the teeth of the indexing wheel 81, the indexing wheel 81 can freely rotate while being subjected to the articulating action by the articulating means 91. ) and the fastener 30 connected thereto can be pulled out from within the device.

Next, the operation of the apparatus of the present invention will be explained with reference to FIGS. 4, 20, and 21.

First, the fastener is introduced into the support 34 (inside the device).
The plurality of fasteners 30 connected to the fasteners 30 (Fig. 27) are inserted into the guides 41m, 41b, 41c (Fig. 3) provided at the distal end portion 41 of the main body 40, and the first fastener is inserted into the fastener injection (Fig. 3). distribution).

When the handle 42 is closed, the fan-shaped gear 49.50
The ejector 61 moves to the left in FIG. 4 via the sliding body 60 and the like, presses the head 32 of the first fastener (FIG. 26) to the left, and releases the fastener and the support 34. Connecting member 35 between
The clasp is injected by cutting the needle with a cutting blade 45b (FIG. 28) provided at the rear end of the needle, and then pushing the head 32 out through the needle. Therefore, in the illustrated embodiment, the handle 42, gears 49, 50, slide 60, etc. constitute actuating means for actuating the ejector 61.

The drive of the pawl 84 with respect to the indexing wheel 81 for sending the next fastener to the fastener ejection (dispensing) position will be explained as follows.
As shown in FIG. 20, the protrusion 60 of the sliding body 60

It engages with the retaining part 85a at the front (left side in FIG. 20) of the link (extension part) 85, and moves the link (extension part) 85 to the left. With this, the claw 8 pivoted on the link (extension part)
4 swings clockwise, the tip 84c (FIG. 16) of the pawl 84 disengages from the indexing wheel 81 and becomes ready for indexing single drive. Next, when the handle 42 is released, the handle 42 rotates clockwise in FIG. 4 due to the action of the elastic return device 70, and the slide body 60 and the ejector 61 move to the right. When the ejector 61 is pulled back from the needle, the protrusion 6°f of the slider 60 becomes a link (extension).

With conventional models, even if the handle is closed slightly,
means for driving the indexing wheel; the indexing wheel is positioned in a state ready to be driven; therefore, when the nodle is released, the next fastener is sent to the injection (dispensing) position by driving the indexing wheel; During the next clasp ejection operation, the ejector must simultaneously eject two clasps, the one remaining in the needle and the new one, which causes jams and the like. Also, in devices where the indexing drive means is positioned in the indexing wheel ready state before the clasp is fully pushed into the needle, the handle may be slightly closed and then released). Upon release of the handle, the indexer single drive drives the indexing wheel to advance the next clasp to the ejection (dispensing) position, which is completely disposed within the needle. or fully), the indexing wheel is unable to rotate due to the uninserted clasp remaining;
The device could become inoperable.

According to the present invention, as described above, the pawl 84 is positioned at the end of the movement of the ejector into the needle in a ready state for driving the indexing wheel. It is possible to achieve a coordinated operation of the feeding of fasteners into and the ejection of fasteners from the device.

28-32, a preferred construction of needle 45 shown in FIG. 4 is shown. The needle consists of two parts mechanically secured to each other, one part designated 45e and the attachment part designated 45f. This mounting portion is preferably constructed from hard or rigid plastic, while portion 45e is preferably constructed from metal. The needle is inserted into the cutting edge 45 at the rear of the slot 45a1.
