Abstract

An apparatus for transporting a bobbin between a winder and spinning frame. A curved transporting path is provided contiguously between a vertical transporting path and a horizontal transporting path, and a conveyor belt is disposed to extend along these paths. A cover which covers the bobbin transporting paths along a length thereof is provided.

Claims

1. A bobbin transporting apparatus in which a spinning frame and a winder are interconnected directly to each other by means of a cop transporting path and a bobbin transporting path, comprising:

a transporting conveyor belt for conveying said bobbins in a substantially vertical direction along a first portion of said bobbin transporting path and in a substantially horizontal direction along a second portion of said bobbin transporting path;

a support member on which said conveyor belt is supported;

a cover which covers over said conveyor belt;

a support rod; and

a mounting member for mounting said support member on said support rod, said support member having two guide sections for guiding said conveyor belt, and having recessed grooves formed in opposite sides thereof and adapted to be engaged by said mounting member to mount said support member on said mounting member.

2. A bobbin transporting apparatus according to claim 1, wherein said cover has a substantially arcuate cross section defining a passage having a diameter greater than the maximum diameter of an empty bobbin.

3. A bobbin transporting apparatus according to claim 1, wherein said cover has a polygonal cross section defining a passage having a cross sectional area greater than the maximum cross sectional area of an empty bobbin.

4. A bobbin transporting apparatus according to claim 1, wherein said mounting member further comprises a block member slidably inserted in one of said recessed grooves, said block member being secured to said support rod by means of a fastening screw.

5. A bobbin transporting apparatus according to claim 1, wherein said mounting member further comprises a pair of substantially channel-shaped hanger metal members which are fitted on said support rod, each of said metal members having a lower bent section, said lower bent section being configured to fit in one of said recessed grooves.

6. A bobbin transporting apparatus according to claim 1, wherein said mounting member further comprises a support metal member having an interior opening shaped to complement the exterior shape of said cover and to thereby hang on to said cover.

7. A bobbin transporting apparatus according to claim 1, wherein said mounting member further comprises a metal member in the form of a spring plate which has opposite ends, each of said ends being engaged in one of said recessed grooves of said support member, said metal member being securely mounted on said support rod.

8. A bobbin transporting apparatus according to claim 1, wherein said mounting member further comprises a substantially u-shaped spring plate having bent portions formed at opposite ends thereof, each of said bent portions being engaged in one of said recessed grooves of said support member, said spring plate being secured to said support rod.

9. A bobbin transporting apparatus in which a spinning frame and a winder are interconnected directly to each other by means of a cop transporting path and a bobbin transporting path, comprising:

a unitary, continuous conveyor belt for conveying said bobbins in a substantially vertical direction along a first portion of said path and in a substantially horizontal direction along a second portion of said path;

a continuous conveyor support member, said conveyor belt extending through and traveling within said support member;

a conveyor drive device provided adjacent to said belt, said conveyor drive device including;

a motor secured to said support member;

a drive pulley driven by said motor around which said belt is extended; and

at least one tension pulley engaged under pressure with said belt, said belt further including at least one pin extending therefrom upon which said bobbin may be supported; and

nip rollers which are contacted under pressure with said belt and which are spaced to allow passage of said pin therethrough.

10. A bobbin transporting apparatus in which a spinning frame and a winder are interconnected directly to each other by means of a cop transporting path and a bobbin transporting path comprising:

a unitary, continuous conveyor belt for conveying said bobbins in a substantially vertical direction along a first portion of said path and in a substantially horizontal direction along a second portion of said path;

a continuous conveyor support member, said conveyor belt extending through and traveling within said support member;

a conveyor drive device provided adjacent to said belt, said conveyor drive device including;

a motor secured to said support member;

a drive pulley driven by said motor around which said belt is extended; and

at least one tension pulley engaged under pressure with said belt, said belt further including at least one pin extending therefrom upon which said bobbin may be supported; and

a nip roller having a radius greater than the length of said pin and having an annular recessed groove to allow passage of said pin in the center of an outer periphery thereof, said nip roller contacted under pressure with said belt.

11. A bobbin transporting apparatus in which a spinning frame and a winder are interconnected directly to each other by means of a cop transporting path and a bobbin transporting path, comprising:

a unitary, continuous conveyor belt for conveying said bobbins in a substantially vertical direction along a first portion of said path and in a substantially horizontal direction along a second portion of said path,

a continuous conveyor support member, said conveyor belt extending through and traveling within said support member;

at least one pin fixed on said conveyor belt; and

a bobbin throw-in station adjacent said first portion of said path, said station including a guide chute which is secured to said support member, said guide chute having a front portion configured so as to allow a bobbin to be admitted into said guide chute, and a bobbin receiving gap formed by a lower plate of said chute and said conveyor belt and being arranged so as to position said bobbin on said pin fixed on said conveyor belt.

12. The bobbin transporting apparatus according to claim 11, wherein a flapper is provided within said guide chute, said flapper being supported for pivotal rocking moliser on a shafe-lo guide a bobbin into said bobbin receiving gap.
