Abstract
A pneumatic fastener inserter and hopper for the same is disclosed for use in inserting fasteners into material being secured. The hopper comprises a rotatable drum which tumbles the fasteners therein into position so that the shanks thereof protrude outwardly between spaced-apart bars. The fasteners are discharged from a discharge opening formed in the hopper and are delivered to a magazine which is in communication with an entrapment apparatus which feeds the fasteners to a feed tube under pressure. The air pressure in the feed tube delivers the individual fasteners to the inserter with the fastener being positioned between pivotally movable head fingers which open to receive the fastener to position the same for subsequent insertion and which pivot to enable the fastener to be driven outwardly therefrom by a piston rod so that the fastener is driven into and through the material being secured.
Description
- This is a continuation application of Petitioners' earlier application Ser. No. 09/376,249 filed Aug. 18, 1999, entitled A PNEUMATIC FASTENER INSERTER AND HOPPER FOR SAME.
- 1. Field of the Invention
- This invention relates to a fastener inserter and more particularly to a pneumatically powered fastener inserter which includes a feed hopper adapted to contain a plurality of fasteners. The feed hopper supplies fasteners to the inserter which inserts individual fasteners into the material or object being secured.
- 2. Description of the Related Art
- T-shaped fasteners normally comprise an elongated shank having a pointed portion at one end thereof and an enlarged head portion at the other end thereof. In most cases, the fastener is provided with a retention means on the shank which resists the fastener being pulled from the material or object being secured. One type of such fastener is commonly referred to as a “Christmas tree” fastener and it includes a plurality of spaced-apart retention members in the form of ribs extending outwardly from the shank thereof. During insertion, the ribs on the shank normally deflect inwardly towards the shank, but the ribs prevent the fastener from being pulled from the material or object once the fastener has been inserted. In many cases, the ribs are swept back to facilitate the insertion thereof.
- In the past, it is believed that the most common method of installing the fasteners in the material being secured was to initially manually force the fastener into position and then use some type of pneumatic hammer or the like to drive the fastener into place. The requirement that the fastener be initially manually placed into position is obviously time-consuming and increases the time necessary to insert the fastener.
- A pneumatic fastener inserter for inserting fasteners, of the type having a shank and an enlarged head, into the material being secured comprising a hopper rotatably mounted on a support in an inclined position with respect to horizontal. The hopper includes an inclined, stationary, closed lower end with the closed lower end including a base plate and an upwardly extending flange at the periphery thereof. A first discharge slot is formed in the flange and a second discharge slot is formed in the base plate which are adapted to permit the discharge of fasteners from the hopper. The hopper also includes a rotatable drive shaft which rotatably extends upwardly and outwardly through the inclined base plate with first and second bar supports being secured to the drive shaft for rotation therewith. A plurality of flat bars are mounted on the first and second bar supports with the bars being spaced-apart from one another to define a gap between adjacent bars. The lower ends of the bars are partially received by the flange which extends from the base plate. The fasteners are placed in the interior of the hopper in a random bulk fashion with the hopper being rotated by a motor or the like as required. As the hopper rotates, some of the fasteners in the hopper position themselves so that the shanks thereof extend outwardly from the hopper between the bars. Eventually, the fasteners move, by gravity, to the lower ends of the bars upon which they are supported. When a protruding fastener is rotated into alignment with the first discharge slot in the base plate and the second discharge slot in the flange, the aligned fastener falls from the interior of the hopper into a pair of horizontally spaced and vertically disposed magazine members so that the fasteners are stacked one upon the other therein. The hopper is only rotated when the uppermost fastener in the magazine members has been lowered to a predetermined position. The hopper is then rotated to supply additional fasteners to the magazine members with the rotation of the hopper being discontinued when the stacked fasteners in the magazine members have reached a predetermined level. The lower ends of the magazine members are in communication with a conventional entrapment apparatus which supplies one fastener at a time, upon demand, to an elongated flexible tube or hose which extends to the pneumatic inserter. A fastener is delivered to the inserter by way of air pressure and passes downwardly therethrough to a position between first, second and third head fingers which are pivotally mounted in a head adapter selectively secured to the lower end of the inserter. The inserter is manipulated so that the protruding pointed end of the fastener is placed into position with the trigger of the inserter then being activated which causes an air driven piston rod to strike the head of the fastener to drive the fastener downwardly (outwardly) from the pivotal head fingers which pivot outwardly against the resiliency of an O-ring extending therearound. When the fastener has been inserted into the material or object being secured, the cycle may be repeated.
- It is therefore a principal object of the invention to provide a pneumatic fastener inserter and hopper for the same.
- It is a further object of the invention to provide a pneumatic fastener inserter for inserting fasteners into material being secured.
- Still another object of the invention is to provide a rotatable fastener hopper which permits fasteners to be placed therein in a bulk and random fashion and which includes means for supplying the individual fasteners to a pneumatic fastener inserter.
- Still another object of the invention is to provide a pneumatic fastener inserter which may be easily modified to accommodate various types and sizes of fasteners.
- Still another object of the invention is to provide a pneumatic fastener inserter which eliminates the need for manually placing the fastener into position prior to it being driven into the material being secured.
- Still another object of the invention is to provide a pneumatic fastener inserter which is convenient to use.
- Still another object of the invention is to provide a pneumatic fastener inserter which greatly decreases the amount of time required to insert fasteners into material or objects being secured.
- These and other objects of the invention will be apparent to those skilled in the art.

When thehead fingers head adapter 126, the O-ring 140 resiliently or yieldably maintains thehead fingers ring 140 permitting thehead fingers - FIG. 18 illustrates a typical fastener which may be used with the system of this invention. It should be understood, however, that many different types of fasteners may be used with the system and the
fastener 156 is only shown for illustrative purposes.Fastener 156 includes ashank 158 having a point 160 at one end thereof. At the other end ofshank 158 is anenlarged head 172.Shank 158 normally will have some form of retaining means thereon to resist the removal of the fastener once it has been inserted. In this case,shank 158 includes a plurality offlexible ribs 174. Thefastener 156 is sometimes referred to as a “Christmas tree” fastener. - In operation, a plurality of the
fasteners 156 are placed into the hopper through one of the openings inwheel 50. Thefasteners 156 are placed into the hopper in a random, bulk fashion. Thedrive motor assembly 28 is then activated to cause theshaft 30,wheels bars 54 positioned onwheels bars 54 are being rotated, thefasteners 156 tumble with theshanks 158 of many of thefasteners 156 protruding outwardly through the spaces 56 between thebars 54. Such protrusion generally occurs when thebars 54 are in the four o'clock to eight o'clock position relative tobase plate 38. Once theshank 158 of afastener 156 has been extended outwardly through a space 56, continued rotation of thebars 54 causes the fastener so positioned to gradually work downwardly on thebars 54, as the hopper is rotated, until theshank 158 comes into contact with the upper edge of theflange 40 with a portion ofhead 172 of thefastener 156 being positioned between the outer periphery ofwheel 49 and the inner surface offlange 40 and a portion of thehead 172 being positioned between the outer periphery ofwheel 49 and the inside surface of a pair ofbars 54 which prevents thefastener 156 from falling inwardly from its supporting bars as the same rotates the fastener from the nine o'clock position to the three o'clock position. When thefastener 156 so positioned has come into communication with thedischarge slots head 172 of thefastener 156 and theshank 158 of thefastener 156 will move downwardly through thedischarge slots inner end 62 of thearm 60 and theflexible sheet member 68 engage protruding portions of fasteners, except for those fasteners which are positioned at the outer end offlange 40, to cause the fasteners not properly positioned to fall back into the basket. - As the
fastener 156 is discharged from the hopper by way of theslots head 172 will be received by theslots magazine members sensor 78 senses that the level of thefasteners 156 stacked in themagazine members sensor 78. The hopper is continued to be rotated until thesensor 80 senses that the stack of fasteners in the magazine has reached the level of thesensor 80. - The entrapment means82 is conventional in fashion and is controlled so as to deliver one
fastener 156 at a time to thetube 20 as demanded by theinserter 14. Assuming that theinserter 14 has just been activated and it is necessary to provide another fastener to theinserter 14, the entrapment apparatus 82 supplies a fastener to the inlet end of thetube 20 with pressurized air forcing the fastener, point first, down the length of thetube 20 to theinserter 14. The discharge end of thetube 20 is received by the recessedareas tube bracket 98. Pressurized air deliversindividual fasteners 156 to thehead fingers tube 20 causes the periphery of thehead 172 of thefastener 156 to come into contact with thetapered surfaces 152 on each of thefingers ring 140 until the periphery of thehead 172 is received in thegroove 148 in each of thehead fingers fingers head 172 to be positioned in thegroove 148, the air behind the fastener is exhausted through the fingers which causes thefingers ring 140 so that thefastener 156 is positioned in thefingers shank 158 will protrude from the outer ends of thehead fingers - When it is desired to insert a
fastener 156 into or through the material being secured, the point of the fastener is properly positioned and the inserter is actuated in conventional fashion which causes the air in theair accumulation chamber 96 to drive thepiston rod 102 outwardly or downwardly so that thepiston rod 102 strikes thehead 172 of thefastener 156 to drive thefastener 156 outwardly with respect to thehead fingers ring 140. The force of thepiston rod 102 striking thehead 172 of thefastener 156 drives the fastener into the material and through the material being secured. - It should be noted that the feed hopper of this invention, while being ideally suited for use with the
particular inserter 14 described herein, may be adapted for use with other types of inserters. It should also be noted that although theinserter 14 of this invention is ideally suited for use with a feed hopper such as described herein, other types of feed hoppers will function satisfactorily with the inserter of this invention. For example, the fasteners could be supplied to the head fingers by a magazine, strip, etc. - The pivotal head fingers are an extremely important aspect of the inserter. The pivotal movement of the head fingers enables the head fingers to pivot open so that a fastener may be properly be positioned therebetween. The head fingers, by way of their pivotal action, also permit the fasteners to be driven outwardly therefrom by the piston rod. The fact that the head fingers are removably secured to the head adapter enables different sizes and shapes of the fingers to be utilized to accommodate various types of fasteners.
- Thus can be seen that the invention accomplishes at least all of its stated objectives.
