Abstract
Abstract A cop supplying apparatus in an automatic winder includes a full cop delivery conveyor belt and an empty cop delivery conveyor belt arranged along each of a plurality of winding units of the winder. A cop fitted on an individual cop deliverying carrier is travelled on the conveyor belt and a passage for receiving the carrier from the conveyor belt is formed in each winding unit. The cops are located at predetermined position of the passage and after a predetermined number of carriers have been stored on the passage, subsequent cops are blocked by the last carrier stored in the passage. The device for delivering the cop to the yarn feed position from the conveyor belt is constructed by a rotary disc and guide plates which are forming the passage for the carrier on the disc.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
In an automatic winder, for winding yarn from a cop to a package wherein said cop comprises yarn wound upon a bobbin, having a plurality of winding units, the improvement comprising a cop supply system consisting of: a device for carrying the cop, said device supporting the cop thereon by engaging said bobbin; conveyor means for transferring said device to each winding unit of the automatic winder; means for supplying the cop to the winding unit and for feeding a yarn from said cop to be wound, while retaining said cop on said device; and means for transferring said device carrying the unwound empty bobbin from the winding unit.
Claim 2
Dependent Claim
109 words
In an automatic winder, for winding yarn from a cop to a package wherein said cop comprises yarn wound upon a bobbin, having a plurality of winding units, the improvement comprising a cop supply system consisting of: a device for carrying the cop, said device supporting the cop thereon by engaging said bobbin; conveyor means for transferring said device to each winding unit of the automatic winder; means for supplying the cop to the winding unit and for feeding a yarn from said cop to be wound, while retaining said cop on said device; and means for transferring said device carrying the unwound empty bobbin from the winding unit.
Claim 3
Dependent Claim
60 words
A cop supplying system as claimed in claim 1, wherein said device for carrying said cop is a tray comprising a disc-like base to be placed on the conveyor means, a disc-like stand mounted on the top face of said base, and a peg vertically projected from said stand; said peg being configured so as to support said cop thereon.
Claim 4
Dependent Claim
65 words
A device for carrying a cop as claimed in claim 2, wherein an opening is communicated from a hollow interior portion of said peg through said stand and said base, forming an opening on the face of said base resting upon the conveyor, and wherein an air jet hole, communicated to said hollow interior portion, is formed on the top face of the said peg.
Claim 5
Dependent Claim
107 words
A cop supplying system as claimed in claim 1, wherein said conveyor means comprises a full cop delivery conveyor belt; said means for transferring said empty bobbin from said winding unit comprises an empty bobbin delivery conveyor belt; said conveyor belts being arranged along each of the plurality of winding unit of the winder; and said means for supplying a cop to the winding unit includes cop delivery passages, comprising a first passage and a second passage, formed to pass through said winding unit between said conveyor belts; said passages being defined by a first guide plate, and a second guide plate confronting said first guide plate.
Claim 6
Dependent Claim
81 words
A cop supplying system as claimed in claim 4, further including a third cop delivery passage for guiding said device, formed between a guide face of a third guide plate, secured to the winding unit at the side portion of the full cop delivery conveyor belt, and a guide face of the second guide plate confronting the third guide plate so that said device is guided by said third passage from said full cop delivery conveyor belt to said first passage.
Claim 7
Dependent Claim
188 words
A cop supplying system as claimed in claim 5, wherein said device for carrying said cop is a tray comprising a disc-like base to be placed on said conveyor, a disc-like stand mounted on the top face of said base, and a peg vertically projected from said stand; said peg being configured so as to support said cop thereon; and wherein the width of said passages is slightly larger than the diameter of said stand of said tray, the lower surface of said first passage being formed into a freely rotatable disc, and the lower surface of said second passage being formed into a plain plate, said plain plate and said disc being coplanar but having a clearance formed therebetween, said clearance being further formed at a position whereat said cop is placed for taking out the yarn during winding, and said clearance further serving as a passage for jetting air from a nozzle through an opening in the bottom surface of said base communicating with a hollow interior portion of said peg and thence through an air jet hole formed on the top face of said peg.
Claim 8
Dependent Claim
138 words
A cop supplying system as claimed in claim 6, wherein a turning lever, for positioning the cop and discharging the bobbin supported on the peg of the tray, is provided swingably about a shaft supported on the plain plate; said turning lever having a first position wherein it falls in abutting contact with the disc-like stand of the tray, said turning lever including a curved guide face means for inhibiting delivery of a subsequent tray having a fresh cop fitted thereon, and a second guide face means for pushing out the tray bearing said bobbin and discharging it along said second passage; and a second position wherein a hook portion formed thereon is able to project into said first passage and contact the stand of the tray bearing the cop to set said cop at the winding position.
Claim 9
Dependent Claim
123 words
A cop supplying system as claimed in claim 1, further comprising: cop passage and bobbin passage detecting switches disposed adjacent said conveyor means and said means for transferring the device carrying the empty bobbin, respectively, to count full cops entering and empty bobbins exiting said automatic winder; counter means for calculating the total number of full cops present within said winder based on signals from said detecting switches; and means for admitting to said winder additional of said devices carrying full cops when said counter means indicates that less than a predetermined capacity of full cops are within said winder so that the same number of full cops are supplied to the winder as the number of empty bobbins discharged from the winder.
