Oct. 7,1975 Sheet 2 of 2 Pamnt APPARATUS FOR APPLYING TUBULAR I NECKBANDS TO CONTAINERS BACKGROUND OF THE INVENTION An existing apparatus for applying plastic bands to the capped necks of containers, such as apothecary bottles, is described in Food & Drug Packaging, V01. 25, Number 3, Aug. 5, 197 l It feeds shrinkable plastic tubing over a floating mandrel between the inner lips of a pair of invertedU-cup packing rings mounted within a feeding sleeveuThe lips of the packing rings are, however, liable to slip when they become coated with dust or wear. Another existing apparatus described in US. Pat. No. 3,523,052 intermittently applies a troublesome vacuum to gripping jaws. An object of this invention is to provide a simple dependable apparatus for feeding tubular band stock over the necks of containers, which is not prone to slip because of wear, dust accumulations or for any other reason.
SUMMARY In accordance with this invention a tubular diaphragm is secured inside the feeding sleeve between the inverted U-cup packing rings. Fluid pressure is admitted between the sleeve and the diaphragm in the downstroke of the sleeve to make the diaphragm positively grip the tubular band stock against the mandrel, which is provided with an antifriction surface, to facilitate feeding of the band stock material down over the capped necks of the containers.

DESCRIPTION OF THE PREFERRED i EMBODIMENT (not shown) in an automatic form of this invention similar to the conveyor" described in US. Pat. No.
O drel sleeve 26.
3,523,052, which utilizes vacuum gripping jaws to feed band stock material; Tubing 12" is advanced over capped neck 16. bya mandrel and sleeve assembly 20, which continuously reciprocates down and up on guide rods 22 through yoke 25 between upper supports 21- and lower supports 23 in response .to the reciprocating movement of prime mover 27 connected to yoke 25. Reciprocating prime mover 27 is, for example, a. reciprocating linkage 33 driven byanelectric motor.
Mandreland-sleeve assembly 20 includesa central mandrel 24and a rigid outer sleeve 26- which grip tubular band stock 12 between them. Stop pins 28 arrest the upward movement of mandrel 24 by engaging its tapered nose 30.- FIG. 1 alsoshows cut-off saw 32, such as a-jewelers saw, rotated by .a prime mover 34 (such as an electn'cmotor)- Saw 34 is inserted into and out of cutting position by prime mover- 35 (such as an air cylinder) to cut tubing stock 12 about capped neck 16 after it is fed' into place,as laterillustrated and'described. i
Details :of sleeve and floating mandrel assembly 20' are shown in FIG. 3. Mandrel 24 has stainless steel axial core 36 with tapered nose 30 mounted above and inverted cup 38 mounted below it. Nose 30 and tapered cup 38 are also both made, for'example, of stainlesssteel. A slippery antifriction polytetrafluoroethylene or polytrifluorochloro-ethylene sheath 40 is mounted about core 36 between nose 30 and inverted cup 38 to urethane rubber, having a hardness for. example of Shore. U-cup packing .rings 44 are also made of rubber, such as Buna-N. Tubular diaphragm 46- has enlarged flanges 48 at its upper and lower ends, which are secured in annular grooves'50 within sleeve 26 next to outer recesses 42 which receive U-cup packing rings" 44. Flanges 48 are sealed within recesses 50,"f0r example, by a cement such as an epoxy, cyano acrylate or anaerobic polyester to provide a sealed annular space 1 52jbetween diaphragm 46 and. the inner wall of man- Tube 54 is inserted through the wall of mandrel sleeve 26 into communicationwith annular chamber 52 through distributing ring 56 to provide a fluid pressure thereto from conduit 58such as compressed air of about four psi. The compressed air forces tubular diaphragm 46 into firm contact about tubular plastic stock 12 which is in turn forced against sheath 40 of mandrel 24. This in conjunction with the grasping action of inner lips 60 of U-cup packing;rings,44 feeds band stock 12 down over mandrel 24 with its lower cup 38, as shown in FIG. 3, over capped neck 16 of container 18 onto which the band stock 12 is applied. Downward feeding ofthe tubular band stock over they capped necks is accomplished after bottom end 38 .of mandrel 24 strikes capped neck 16.-Sleeve 26 thereafter continues mov'ing downwardly until reciprocating linkages. 33 is fully extended (shown in'FIG. 1)., This overtravel of sleeve 26 pulls band stock 12 down and extendsit past mandrel 24 over the capped neck 16 of container 18.
FIG. 4 shows mandrel 2 4 and its lower cup 38 moved upwardly a slight distance away from capped neck 16, with pressure still expanding diaphragm 46 against sheath 40 to provide a slight clearance 62 between the bottom of mandrel 24 and the top of capped neck 16 above which cut-off saw 32 is actuated to sever the extended tubular band material slightly above cap neck 16. As sleeve 26 is moved upwardly after cutting off band stock 12, air pressure through tube 58 is terminated by detector 29 which actuates valve 59, this permits sleeve 26 to slip upwardly relative to band stock 12 after mandrel nose 30 strikes stops 28 and grasp a new length of stock for installation over the next capped neck 16. After extended tubular band stock 12 is severed, the containers 18 are transported to a shrinking heater, such as an infrared heat shrink tunnel, where heat is applied to dry and shrink the severed bands around cap necks 16. Prior to shrinkage the severed pieces of band stock 12 fall or are tamped down to abut against shoulders 64 of containers 18 to make sure that they cover the exposed neck portions 66 of capped necks 16 after shrinking as shown in FIG. 5. This final downward tamping of the severed portions of tubular band stock 12, if necessary, can be manually performed or automatically by any suitable automatic tamping means (not shown). Final drying of the shrunk bands may occur during storage.
When perforated stock is used with this apparatus, disc 31 in FIG. 3, serves as a plow to separate the perforations.
While mandrel and sleeve assembly 20 are moving upwardly, air pressure is exhausted from annular chamber 52 via control air valve 59 connected to line 58 and actuated by the prime mover 27 through detector 29. This release of pressure from the tubular diaphragm 46 allows sleeve 26 to overtravel when mandrel 24 strikes its upper stops 28. The length of this overtravel determines the length of band stock 12 dispensed on cap 16.
At this upper travel point, air pressure is re-applied by detector 29 and control valve 59 to annular chamber 52 in back of tubular diaphragm 46 to maintain tubing 12 firmly gripped thereby to prevent any slippage between the tubular band stock 12 and the feeding sleeve 26, repeating the cycle. The air pressure is released by valve 59 actuated by detector 29 of a slight distance after the bottom of the down stroke of sleeve 26 and prime mover 27 (after band stock 12 has been severed). Diaphragm 46 is accordingly actuated to grasp on the down stroke and to release on the up stroke relative to band stock 12 and mandrel 24, after band stock 12 has been severed.
Although arrangements of this type without the tubular diaphragm start to slip because of dust deposits after a limited number of operating strokes, apparatus has operated effectively for as much as about fifty thousand cycles before it was'necessary to wipe dust accumulations off packing rings 44. Successful overall operation through many hundreds of thousands of operations has also been achieved.
For the larger diameters of tubing stock 12, axial core 36, FIG. 3, should be made for instance out of hollow aluminium tubing, thereby reducing the weight of mandrel 24. This weight reduction would prevent said mandrel from falling out of feeding sleeve 20, when air pressure is exhausted from diaphragm 46 on the upstroke.
