  • the belt (which may be of circular cross-section) may extend along the path of the holding device and may be resiliently biased against the spindles such that horizontal translating movement of the holding device relative to the belt effects rotation of the spindle. Additionally or alternatively, the belt may be driven to rotate the spindle at a speed independently of the speed of the conveyor chain. Of course, other means may be provided to rotate the spindle.
  • the spindle may be equipped with a sprocket for engaging a chain in a manner similar to that just described above with respect to the spindle groove and belt. Accordingly, various means may be employed to rotate the spindle within the broad scope of the present invention.
  • the gripping device 68 is in the form of a chuck that is mounted on the spindle 66 for telescoping sliding movement between upper and lower positions.
  • the lowermost position is determined by the head of a plug 75 threaded into the lower end of the spindle.
  • the head of the plug also herein referred to as a plunger, protrudes radially beyond the spindle and forms a stop shelf that limits axial downward movement of the chuck relative to the spindle.
  • the maximum upper range of movement of the chuck relative to the spindle is limited by engagement of a set pin (or dog) 76 against the upper end of a slot 77 in which the radially inner end of the set pin moves.
  • the chuck normally will not be raised to such uppermost position, as the chuck need only be raised sufficiently to discharge a bottle therefrom in the hereinafter described manner.
  • the set pin 76 which functions as a key, cooperates with the slot to key the chuck to the spindle for common rotation.
  • the chuck may be replaced with different sizes and/or types of chucks by simply removing (unscrewing) the plug 75 from the spindle which allows the chuck to slip off the end of the spindle. A new chuck or other gripping device may then be reassembled to the spindle as may be desired.
  • the chuck 68 has a main body portion 80 from which a circumferential arrangement of gripping fingers 81 depend axialiy to define therebetween a socket for receiving the neck of a bottle.
  • the neck of the bottle has an externally threaded upper portion that terminates at its lower end at an annular flange or bead 83.
  • annular neck flange 84 Axialiy spaced below the annular bead 83 is an annular neck flange 84 having a flat underside, as of the type commonly provided on bottles and the like for use in conjunction with air conveyors.

  • an annular band such as an O-ring has been used to resiliently bias the gripping fingers radially inwardly into engagement with the article being gripped.
  • the fingers are provided at their radially outward sides with a retaining groove like that shown at 87 in Fig. 4.
  • this arrangement has been suitable for many applications, problems arise when the O-ring and/or gripping fingers become coated by overspray or otherwise with material being sprayed or otherwise applied onto the exterior of the bottle or other article. Such coating of the chuck may adversely affect its performance, thereby necessitating cleaning and/or replacement of the chucks which heretofore has been a somewhat tedious and time consuming task.
  • a tubular shield or masking sleeve to prevent the gripping fingers from becoming coated by overspray or otherwise with material being sprayed or otherwise applied onto the exterior of the bottle or other article.
  • the masking sleeve 90 that is telescoped over the gripping fingers, preferably is a tubular flexible thin walled body that closely circumscribes the gripping fingers preferably over the entire axial length thereof.
  • the sleeve may extend to the bottom of main body portion 80 to completely cover the exterior surfaces of the fingers. However, as shown, the sleeve may terminate short of the main body portion and an O- ring 92 is provided to fill the gap and form a continuation as part of the sleeve.
  • the elastomeric masking sleeve which preferably is made of an elastomeric material, resiliently urges the gripping fingers radially inwardly for engaging the neck of the bottle.
  • the masking sleeve preferably has formed integrally therewith a radially thickened annular portion 91 that functions as an elastomeric band much like the O-rings previously used in similar prior art chucks.
  • the radially inwardly protruding annular band is captured in the grooves 87 formed at the radially outer sides of the gripping fingers for retaining the sleeve on the chuck, i.e., to prevent the chuck from telescopically slipping off the chuck.
  • the masking sleeve 90 will protect against overspray from accumulating on the gripping fingers. Instead, any overspray will accumulate on the exterior surface of the masking sleeve.
  • the masking sleeve may be slipped off of the chuck and manipulated by squeezing, flexing and/or twisting to cause the built-up and hardened layer of spray material to crack and fall away (or otherwise separate) from the masking sleeve.
  • the masking sleeve may then be reinstalled on the same or another chuck.
  • the sleeve should be made of a material compatible with the particular spray material being utilized to coat the bottle or other article.
  • the main body 80 of the chuck has a transverse dimension greater than the circumferential arrangement of gripping fingers 81 . Accordingly, there is formed at the bottom of the main body a shoulder or abutment surface 93 that extends radially outwardly beyond the gripping fingers. The main body also has an upper abutment surface 94 that extends radially outwardly from the spindle. As is preferred, the main body may be generally cylindrical to form an annular abutment surface for engagement by an actuating cam or cams that control the position of the chuck on the spindle in the hereinafter described manner.
  • a bottle B is telescopically inserted at its neck and into the socket formed by the gripping fingers when the chuck is in its lowermost or axialiy outer position.
  • the fingers 81 will be cammed radially outwardly against the resilient restoring force exerted thereon by the masking sleeve including, in particular, the radially thickened band portion 91 thereof, as well as against the resilient restoring force of the fingers themselves.
  • the chuck, including the gripping fingers is made of a material such as polytetrafluoroethylene (PTFE) which has some inherent flexibility that is supplemented by the elastomeric masking sleeve and/or band.
  • PTFE polytetrafluoroethylene
