- the preferred embodiment of the collection means 10 of the present invention is illustrated in the drawings attached to a bank 12 of knitting machines that knit ladies seamless hosiery or mens, womens and childrens socks or similar articles.
- the particular knitting machines 14 illustrated are circular knitting machines made by Singer- Fidelity, Inc., of Philadelphia, Pa., and referred to by the manufacturer as model LBMD.
- These knitting machines 14 are of conventional construction and include an air pump 16 from which air is forced through the vertical tube 18 to the knitting head 20 where the stockings are knit. The air from the vertical tube 18 blows the stockings downwardly through the interior tube 22 to an exterior tube 24 at the bottom of the machine 14.
- These machines are conventionally constructed with a collection box (not shown) at the upper end of the exterior tube 24 and the operator must move from machine to machine to remove the stockings accumulated in the collection box of each machine.
- the individual knitting machines 14 are modified by removing the collection box and cutting ofi the exterior tube 24 above the bottom elbow 26 that connects the exterior tube 24 with the interior tube 22.
- a delivery tube 28 is mounted adjacent each machine 14 and has an elbow 30 with a flared opening 32 posi-' tioned slightly above the end of the exterior tube 24.
- the delivery tube 28 extends horizontally from the elbow to carry stockings blown by the air pump 16 from the knitting machines 14.
- the flared opening 32 ofthe elbow 30 of the delivery tube 28 facilitates transfer of the stockings from the exterior tube 24 to the delivery tube 28 and the spacing of the elbow 30 above the exterior tube 24 permits excess air to escape.
- the delivery tubes 28 are mounted in brackets 34- on the sides of the knitting machines 14 and extend therefrom to a position above a main conveyor tube 36.
- An inclined elbow 38 is attached to the main tube end of the delivery tube 28 to direct the stockings downwardly and forwardly through an opening 40 in the top of the main conveyor tube 36.
- the main conveyor tube 36 is substantially larger in diameter than the delivery tubes 28 and has a narrow conveyor belt traveling forwardly in the direction of the arrows along the bottom of the tube so that stockings 44 deposited in the main conveyor tube 36 from the delivery tubes 28 will be carried by the conveyor belt to the collection end 46 of the tube.
- a material such as canvass and frictionally engages the stockings to pull them along the bottom of the tube, and, because of this frictional engagement, the conveyor belt 42 may be considerably narrower than the width of the stockings being carried thereon, With the overlapping portions of the stockings sliding along the interior of the tube.
- the conveyor belt 42 passes from the collection end 46 of the main tube 36 around a drive pulley 50, an idler pulley 48, and around an adjustable idler pulley 52 from which the conveyor belt 42 travels rearwardly through a lower chamber 54 beneath the main conveyor tube 36.
- the main conveyor tube 36 is circular in cross-section and the lower chamber 54 constitutes a portion of a circular tube secured to the bottom of the main tube with the main tube and associated lower chamber supported at intervals along the length thereof by Y-shaped supgoits 56. This is clearly illustrated in cross-section in At the rear of the main conveyor tube 36 the conveyor The conveyor belt isthe adjustable idler pulley 52 at the collection end '46 of the main tube 36 and-the movement of the conveyor belt 42 is controlled by the drive pulley 50 which is driven by an electric motor 60.
- the main conveyor tube tapers as at 62 and is connected by an elbow 64 to a vertical depositing tube 66 having a U-shaped upper end 68 that opens above a collection not 7 0.
- the stockings 44 are forced through the tapered portion 62 of the main tube 36 and through the depositing tube 66 into the collection net 70 by means of an air blast from a nozzle 72 in the side of the main conveyor tube 36 spaced a short distance back of the collection end 46 thereof and directed forwardly.
- the air is delivered to the nozzle 72 by a conduit 74 leading from a pump or other suitable supply (not shown).
- the diameter of the depositing tube 66 is substantially less than the diameter of the main conveyor tube 36 as seen from the tapered portion 62 that connects the two pipes. This reduction in diameter afiects a relative increase in the speed of the air blast and thereby facilitates the transportation of the stockings 44 upwardly through the vertical depositing tube 66.
- the delivery tubes 28, main conveyor tube 36 and depositing tube 66 are made of plastic material and are transparent to permit inspection during operation. Also, the smoothness of the plastic is advantageous as it does not snag or create a drag on the moving stocking that could prevent movement of the stockings through the tubes.
- the delivery tubes 28 are 3 /2" in diameter and the main conveyor tube 36 is 6" in diameter.
- the conveyor belt 42 moving along the bottom of the main tube 36 is driven at approximately 120 feet per minute.
- the tapered portion 62 reduces the diameter of the main tube 36 to the 3 /2" diameter Which is the diameter of the depositing tube 66.
- the air blast is obtained using a nozzle 72 having a Ms" opening through which the air passes from a supply wherein the air is under a pressure of approximately 25 to 35 pounds per square inch. This force of the air blast lifts the stockings 44 from the conveyor belt 42 and upwardly through the depositing tube 66.
- the conveyor belt 42 is 2" wide and 1 thick and the lower chamber 54 through which the belt returns constitutes half of a 3 /2 diameter tube.
- the stockings knit in the knitting machines are blown through the delivery tube 28 into the main conveyor tube 36 in which they are carried by the conveyor belt 42 until they are blown by air from the nozzle 72 through the depositing tube 66 and into the collection net 70 where the Worker inspects and turns the stockings.
- the stocking marking indicates the machine and the worker can simply press a switch in a panel of switches or other arrangement located at the collection point to turn olf the particular machine until the fixer can make the necessary machine corrections.
- a trigger 76 can be lowered 'into the delivery tube 28 at the top of the elbow 30.- As shown in FIG. 4, this trigger 76 is pivotally mounted on a pin 78 and is normallyheld outside of the elbow30 by a resilient stop finger 80 secured to the outside of the elbow 30 and extending into the path of the trigger 76.
- the trigger 76 is forced past the resilient stop finger 80 into the elbow 30 and as the trigger 76 is slightly longer than the inner diameter of the delivery tube 28, it will stop against the bottom of aaageer 4 the elbow 30 and permit removal of the stocking through the trigger opening in the tube.

No. 78,061 11 Claims. (Cl. 302- 12) The present invention relates to an article collection means and method, and more particularly to a method and means for collecting articles from a plurality of stations to a central collection position by means that deposit the articles from the individual stations onto a main conveyor from which the articles are collected at the central collection position.
In most processing and handling operations the transporting of the articles from one station to another is an important element and it is often required that the articles be transported from individual stations to a central location. The present invention is directed to a method and means that greatly facilitate this transportation and eliminate intermediate handling of the articles, thus reducing the cost of production and pro viding a continuous flow of articles without interruption.
The present invention is particularly adaptable to the collection of hosiery from individual circular knitting machines to a central collection area which has not heretofore been accomplished in a satisfactory and commercially suitable system without intermediate handling. Hosiery are usually accumulated at the individual knitting machines and an operator must move from machine to machine to pick up the hosiery for further handling or processing. This is time consuming and expensive and expensive and therefore undesirable from a commercial standpoint.
By the present invention means are provided to deliver the articles, such as hose, from individual stations onto a main conveyor means that transports the articles toward a central collection point and includes means for removing the articles from the conveyor to the collection point.
In the preferred embodiment of the present invention the collection system is connected to a bank of knitting machines from which knit hose are directed by an air blast through delivery tubes that open into a main conveyor tube running along the length of the bank of knitting machines. A conveyor belt runs along the bottom of the main conveyor tube and carries the hose as they are deposited in the tube from thedelivery tubes toward the collection end of the main tube. At the collection end of the main conveyor tube an air blast is directed to carry the hose from the conveyor belt through a depositing tube into a collection net or other container from which they are removed periodically by a worker.
The present collection system can collect hosiery or other articles in any desired number of individual machines and convey the articles in any desired direction to a preferred collection location for expeditious handling and resulting minimization of labor necessary to collect the articles.
The numerous features and advantages of the present invention are apparent from the following description and drawings in which:
FIG. 1 is a front perspective view of a bank of knitting machines with the preferred embodiment of the article collection means of the present invention;
FIG. 2 is a rear perspective view of the bank of knitting machines of FIG. 1;
FIG. 3 is a top plan view of the bank knitting: machines of FIG. 1;
FIG. 4 is a vertical sectional view taken along line 4-4 of FIG. 3; and
FIG. 5 is a vertical sectional view taken along line 4--4 of FIG. 3.
The preferred embodiment of the collection means 10 of the present invention is illustrated in the drawings attached to a bank 12 of knitting machines that knit ladies seamless hosiery or mens, womens and childrens socks or similar articles. The particular knitting machines 14 illustrated are circular knitting machines made by Singer- Fidelity, Inc., of Philadelphia, Pa., and referred to by the manufacturer as model LBMD. These knitting machines 14 are of conventional construction and include an air pump 16 from which air is forced through the vertical tube 18 to the knitting head 20 where the stockings are knit. The air from the vertical tube 18 blows the stockings downwardly through the interior tube 22 to an exterior tube 24 at the bottom of the machine 14. These machines are conventionally constructed with a collection box (not shown) at the upper end of the exterior tube 24 and the operator must move from machine to machine to remove the stockings accumulated in the collection box of each machine.
In the present invention the individual knitting machines 14 are modified by removing the collection box and cutting ofi the exterior tube 24 above the bottom elbow 26 that connects the exterior tube 24 with the interior tube 22.
A delivery tube 28 is mounted adjacent each machine 14 and has an elbow 30 with a flared opening 32 posi-' tioned slightly above the end of the exterior tube 24. The delivery tube 28 extends horizontally from the elbow to carry stockings blown by the air pump 16 from the knitting machines 14. The flared opening 32 ofthe elbow 30 of the delivery tube 28 facilitates transfer of the stockings from the exterior tube 24 to the delivery tube 28 and the spacing of the elbow 30 above the exterior tube 24 permits excess air to escape.
The delivery tubes 28 are mounted in brackets 34- on the sides of the knitting machines 14 and extend therefrom to a position above a main conveyor tube 36. An inclined elbow 38 is attached to the main tube end of the delivery tube 28 to direct the stockings downwardly and forwardly through an opening 40 in the top of the main conveyor tube 36.
The main conveyor tube 36 is substantially larger in diameter than the delivery tubes 28 and has a narrow conveyor belt traveling forwardly in the direction of the arrows along the bottom of the tube so that stockings 44 deposited in the main conveyor tube 36 from the delivery tubes 28 will be carried by the conveyor belt to the collection end 46 of the tube. made of a material such as canvass and frictionally engages the stockings to pull them along the bottom of the tube, and, because of this frictional engagement, the conveyor belt 42 may be considerably narrower than the width of the stockings being carried thereon, With the overlapping portions of the stockings sliding along the interior of the tube.
The conveyor belt 42 passes from the collection end 46 of the main tube 36 around a drive pulley 50, an idler pulley 48, and around an adjustable idler pulley 52 from which the conveyor belt 42 travels rearwardly through a lower chamber 54 beneath the main conveyor tube 36.
The main conveyor tube 36 is circular in cross-section and the lower chamber 54 constitutes a portion of a circular tube secured to the bottom of the main tube with the main tube and associated lower chamber supported at intervals along the length thereof by Y-shaped supgoits 56. This is clearly illustrated in cross-section in At the rear of the main conveyor tube 36 the conveyor The conveyor belt isthe adjustable idler pulley 52 at the collection end '46 of the main tube 36 and-the movement of the conveyor belt 42 is controlled by the drive pulley 50 which is driven by an electric motor 60.
At the collectionend 46 the main conveyor tube tapers as at 62 and is connected by an elbow 64 to a vertical depositing tube 66 having a U-shaped upper end 68 that opens above a collection not 7 0.
v The stockings 44 are forced through the tapered portion 62 of the main tube 36 and through the depositing tube 66 into the collection net 70 by means of an air blast from a nozzle 72 in the side of the main conveyor tube 36 spaced a short distance back of the collection end 46 thereof and directed forwardly. The air is delivered to the nozzle 72 by a conduit 74 leading from a pump or other suitable supply (not shown).
The diameter of the depositing tube 66 is substantially less than the diameter of the main conveyor tube 36 as seen from the tapered portion 62 that connects the two pipes. This reduction in diameter afiects a relative increase in the speed of the air blast and thereby facilitates the transportation of the stockings 44 upwardly through the vertical depositing tube 66. In the preferred embodiment of the collection means illustrated in the drawings the delivery tubes 28, main conveyor tube 36 and depositing tube 66 are made of plastic material and are transparent to permit inspection during operation. Also, the smoothness of the plastic is advantageous as it does not snag or create a drag on the moving stocking that could prevent movement of the stockings through the tubes. In one particular commercial embodiment the delivery tubes 28 are 3 /2" in diameter and the main conveyor tube 36 is 6" in diameter. The conveyor belt 42 moving along the bottom of the main tube 36 is driven at approximately 120 feet per minute. The tapered portion 62 reduces the diameter of the main tube 36 to the 3 /2" diameter Which is the diameter of the depositing tube 66. The air blast is obtained using a nozzle 72 having a Ms" opening through which the air passes from a supply wherein the air is under a pressure of approximately 25 to 35 pounds per square inch. This force of the air blast lifts the stockings 44 from the conveyor belt 42 and upwardly through the depositing tube 66.
The conveyor belt 42 is 2" wide and 1 thick and the lower chamber 54 through which the belt returns constitutes half of a 3 /2 diameter tube.
In operation, the stockings knit in the knitting machines are blown through the delivery tube 28 into the main conveyor tube 36 in which they are carried by the conveyor belt 42 until they are blown by air from the nozzle 72 through the depositing tube 66 and into the collection net 70 where the Worker inspects and turns the stockings. When a defect is noted in a stocking the stocking marking indicates the machine and the worker can simply press a switch in a panel of switches or other arrangement located at the collection point to turn olf the particular machine until the fixer can make the necessary machine corrections. V
If for any reason it is desired to retain stockings at the individual knitting machines, rather than allowing them to be collected, a trigger 76 can be lowered 'into the delivery tube 28 at the top of the elbow 30.- As shown in FIG. 4, this trigger 76 is pivotally mounted on a pin 78 and is normallyheld outside of the elbow30 by a resilient stop finger 80 secured to the outside of the elbow 30 and extending into the path of the trigger 76. When it is desired to stop a stocking, the trigger 76 is forced past the resilient stop finger 80 into the elbow 30 and as the trigger 76 is slightly longer than the inner diameter of the delivery tube 28, it will stop against the bottom of aaageer 4 the elbow 30 and permit removal of the stocking through the trigger opening in the tube.
Although the preferred embodiment illustrated in the drawings is adapted for use with a Singer-Fidelity machine, it can also be adapted for use with other machines such as a Scott & Williams, Model KN, which includes a grab mechanism and an air jet to deliver the stockings from the machine, or a Bentley Model KL'rnachine, which.
drops the stockings from the knitting head, or anyof numerous other knittingmachines which automatically deliver knitted stockings at each machine.
Also it should 'be understood that the particular shapes and paths of the various elements of the present invention can be variedfrom that'illustrated in the drawings a central collection station, said means comprising a main conveyor tube extending along said plurality of machines or the like to a central collection station and having openings therein adjacent said knitting machines or the like, delivery tubes extending from said machines to said main conveyor tube and having outer ends aligned with said main conveyor tubes openings for delivery of said hosiery or the like from the machines into the main conveyor tube, means for blowing air through said delivery tubes to transport said hosiery or the like therethrough, the ends of said delivery tubes being spaced from the peripheries of the main delivery tube openings to provide a space for the passage of air to dissipate the excess of air blown from the delivery tubes into the main conveyor tube and minimize turbulence in the main conveyor tube, and means for moving said hosiery or the like through said main conveyor tube.
