ジャーナル フリーThe ever-intensifying struggle for survival by every industry stimulates keener efforts at modernization and cost-paring. Efforts along these lines have been and are still being made in the textile industry also. Such efforts by the textile industry must be pushed with the following major points in mind:
1. Raising of productivity by improving the performance and efficiency of each and every machine.
2. Smooth conveyance of materials and finished products through each frame.
3. Arrangement of machines with the distance between them reduced to a minimum.
4. Productive capacity of each machine not only at present but in the near future should be carefully borne in mind.
5. Simplifying the operating condition of machines and quality control.
6. Elimination of all causes for machine trouble and, especially, devising a perfect method of oiling and cleaning frames.
7. Simplifying the maintenance of each machine and equipment.
8. The frame and equipment modernized should be low in cost and yield a high profit.
9. Devising an easy method to connect each machine in one stage of operation with that in the next stage, due consideration being paid to the quantity of production and the amount of consumption.
10. Diversification and mass-production.抄録全体を表示PDF形式でダウンロード (1015K) -

ジャーナル フリーCAS-TAD is built in two general types. Type A uses Auto-carrier motor-driven from one spinning frame to another. Type B is subdivided into two types. Type B1 is man-driven. Type B2 uses a man-driven carriage.
TAD, again, is divided into two types: the bobbin type which doffs bobbins; and the tube type which doffs paper tubes.
Any type of TAD, once installed on a spinning frame, automatically doffs the spinning frame and then returns to its original position. AD (auto-doffer) uses a 220-V alternate current. AC (auto-carrier) of TAD type A uses a 24-V direct current by battery or an alternate current. TAD travels and doffs intermittently, doffing 8 or 10 cops in one doffing cycle. The time required for TAD to do doffing on the right or left side of a spinning frame and return to its original place is 1/2 minutes for the bobbin type and 4 minutes for the tube type.
The rate of yarn breakage after a spinning frame has been doffed and when it is started is a maximum of 3%. The number of operatives needed to run a TAD is 1 for type A, 1 for type B2 and 2 for type B1. Tne number of spinning frames a TAD doffs is calculable by the following equation: A=ts/td A: number of spinning frames ts: time for making full bobbins of a spinning frame td: time for doffing a spinning frame TAD is equipped with many devices for safety to man and machine.抄録全体を表示PDF形式でダウンロード (1336K) -

ジャーナル フリーThis automatic cop doffer (A.C.D.) can be used directly on the conventional ring spinning frame with only very few modifications of the frame. Its major features are:
(1) The distance from the center line of the spindle to the outside of the A.C.D. is 320mm. The breadth of the carriage of A.C.D. is 945mm, which leaves enough floor space for the locomotion of the carriage on the other side.
(2) Use of a gravity shooting system for cop-arranging and feeding of bare bobbins simplifies mechanisms and conduces to accurate operations.
(3) A double elastic holder system being used to grip both cops and bobbins, lack of uniformity in the outer diameter of the bobbin does not affect doffing.
(4) Despite variations in the relative height of the spindle rail to the floor or floor rail, the body frame of A.C.D, can be held in the same fixed relative position to the spindle rails by adjusting the bottom wheel's fixed position.
(5) Use of friction wheels to drive A.C.D. along the frame side simplifies mechanisms and reduces operating costs. No rail connection from the carriage of A.C.D. is needed.抄録全体を表示PDF形式でダウンロード (736K) -

ジャーナル フリーTo trace the development of a full-automatic auto-doffer simple in mechanism and usuable in conventional spinning mills.
The Doffer
(1)The mechanism used is of an intermittent-movement and multi-spindle doffing system.
(2) The width of the doffer is 189mm.
(3) Conventional ring frames and buildings may be used if there is a space of more than 300mm between the gear-end side (or out-end side) of a ring frame and a pillar.
(4) One person can move the auto-doffer if an auto-doffer carrier is used.
(5) The rails for the auto-doffer carrier need not be laid on the floor.
(6) The doffing time per cycle is about 8sec/10sps.
(7) The end-breakage rate for 10 ring frames as of June 1965 is about 2.5%.抄録全体を表示PDF形式でダウンロード (661K) -

ジャーナル フリーThe Fujibo-type auto-doffer is an automatic doffing machine designed for use with existing ring spinning frames in service in ordinary spinning mills.
It is of the continuous multi-cop doffing type and usuable anywhere if the present arrangement of the spinning frames in a mill leaves a space of not less than 330 millimeters from the nearest pillar to either side of a ring spinning frame in a straight line with one side of its gear-end and out-end frames.
The auto-doffer, specifically built in two symmetrical types for use on either the right or left side of the spinning frame, must be carried separately to one end of each ring spinning frame. Once placed on a pair of rails laid along the sides of the spinning frame, it automatically moves back and forth, doffing cops and donning bobbins in its forward movement at a speed of two per second and returning at four times the speed of its forward movement. The time required for the whole doffing operation is about 2 1/2 minutes.
End-breakage caused by the operation of this machine, including that caused by starting the spinning frame, is about 2.5% öf the total number of spindles, according to experimental data obtained by using this type of auto-doffers on 30 spinning frames. This gives us the assurance that the doffer can be used in any existing mills with complete facility of spinning operations.抄録全体を表示PDF形式でダウンロード (1559K) -
