Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A coil-like article supply device comprising a base, a delivery mechanism mounted on the base, for sequentially delivering a large number of coil-like articles and a rope inserted through the coil-like articles, a separation mechanism for receiving by a prescribed number said coil-like articles delivered from said delivery mechanism along said rope and separating and releasing said prescribed number of coil-like articles one by one with a prescribed timing, a supply mechanism provided facing said separation mechanism and movable for receiving said coil-like articles released from said separation mechanism to supply them to a proper place, a feed mechanism so provided as to be reciprocatingly moved between said supply mechanism and said separation mechanism, for pulling with a prescribed timing said rope inserted into said separation mechanism, and a cutting mechanism provided facing said supply mechanism, for cutting with a prescribed timing said rope pulled by said feed mechanism.
Claim 2
Dependent Claim
149 words
A coil-like article supply device comprising a base, a delivery mechanism mounted on the base, for sequentially delivering a large number of coil-like articles and a rope inserted through the coil-like articles, a separation mechanism for receiving by a prescribed number said coil-like articles delivered from said delivery mechanism along said rope and separating and releasing said prescribed number of coil-like articles one by one with a prescribed timing, a supply mechanism provided facing said separation mechanism and movable for receiving said coil-like articles released from said separation mechanism to supply them to a proper place, a feed mechanism so provided as to be reciprocatingly moved between said supply mechanism and said separation mechanism, for pulling with a prescribed timing said rope inserted into said separation mechanism, and a cutting mechanism provided facing said supply mechanism, for cutting with a prescribed timing said rope pulled by said feed mechanism.
Claim 3
Dependent Claim
38 words
A coil-like article supply device according to claim 1 further comprising means provided between said delivery mechanism and said separation mechanism, for detecting the degree of tension of said rope to control the operation of said delivery mechanism.
Claim 4
Dependent Claim
67 words
A coil-like article supply device according to claim 1 wherein said separation mechanism includes detecting means for detecting whether or not said prescribed number of coil-like articles are received in said separation mechanism, thereby controlling the operation of said feed mechanism in accordance with the detected condition of said detecting means to permit said prescribed number of coil-like articles to be always received in said separation mechanism.
Claim 5
Dependent Claim
37 words
A coil-like article supply device according to claim 1 wherein said delivery mechanism includes a rotary drum wound with said rope carrying a large number of said coil-like articles, and driving means for rotating said rotary drum.
Claim 6
Dependent Claim
87 words
A coil-like article supply device according to claim 1 wherein said separation mechanism includes a slide member, a guide member attached to the slide member, said guide member having a guide hole for passing said coil-like articles and said rope therethrough, a stop piece movably provided on the underside of said guide member so as to permit said guide hole to be opened and closed, and a member for preventing a drop of said coil-like articles disposed in said guide hole other than the lowest coil-like article.
Claim 7
Dependent Claim
41 words
A coil-like article supply device according to claim 1 wherein said supply mechanism includes a pair of moving plates for cooperatively holding said coil-like articles one by one when closed and releasing the held condition of said coil-like articles when opened.
Claim 8
Dependent Claim
28 words
A coil-like article supply device according to claim 1 wherein said feed mechanism includes a pair of feed members for cooperatively sandwiching said rope and pulling it downward.
Claim 9
Dependent Claim
38 words
A coil-like article supply device according to claim 1 wherein said cutting mechanism includes a pair of movable blades attached on the lower side of said feed mechanism, for cutting said rope in cooperation with said feed mechanism.
