Description

[Detailed Description of the Invention] Field of Industrial Application This invention relates to a spinning device, and particularly to a spinning device in which a can is arranged in a specific position relative to the spinning machine.

〓Conventional technology〓 The can arrangement for conventional spinning machines is such that the cans are placed on the back side of the spinning machine across a passage, and the sliver is drawn out from the back side of the spinning machine to the front side and supplied to the spinning unit of the spinning machine. There are known systems in which the sliver is wound up, and in which a can is placed directly below each spinning unit of a spinning machine, and the sliver is drawn upwards from directly below, supplied to the spinning unit, and then wound.

With the configuration where the can is placed on the back side of the spinning machine, the worker keeps an eye on the front of the spinning machine while it is in operation, and when it becomes necessary to replace the can or supply new sliver, he moves to the end of the spinning machine. After going around the spinning machine to the back of the spinning unit and performing operations such as replacing the can and pulling out the sliver and feeding it to the spinning unit, return to the front of the spinning machine to ensure that the sliver is properly fed. It was necessary to check whether the information was correct, which was a waste of effort.

Furthermore, if the spinning machine is constructed so that the cans are placed directly below each spinning unit, it is not possible to use tall cans due to the position of the spinning units, even if the above-mentioned unnecessary labor is not expended. Also, if the can protrudes too far in front of the spinning unit, it will get in the way of work, and the size of the can and space to place it will be limited.In particular, as speeds have increased recently, the amount of sliver consumed has increased, making it difficult to replace the can. As this process became more frequent and as cans became larger, a large space was required to place the cans, making it difficult to carry out.

Therefore, cans are placed on both sides of a spinning machine with a plurality of spinning units arranged back to back, with a working path separated, and the upper part of the spinning machine is arranged so that the working path extends directly above the can for each spinning unit. It has come to be considered that an arm rod is provided and a sliver guide roller is provided on the arm rod.

〓Problems to be solved by the invention〓 The above-mentioned spinning machine, in which multiple spinning units are arranged back-to-back, and cans are placed in front of both sides of the spinning machine, with a working passageway in between, has the above-mentioned spinning machines and working machines placed on the floor of the factory. Since passages and can arrangement areas are provided, there are problems in that the number of spinning machines installed is limited and productivity is reduced.

This invention was made for the purpose of solving the above-mentioned problems by studying the arrangement of cans with respect to a spinning machine.

〓Means for solving the problem〓 This invention provides an upper floor above the lower floor where the spinning machine is arranged, and the upper floor is used as a can arrangement area, and on the floor surface there is a space directly above the spinning unit of the spinning machine. An opening extending over the entire length of the spinning machine is provided in the spinning machine, and the upper floor is provided with a sliver conveying device that can move up and down to sandwich the end of the sliver pulled out from the can and make the end of the sliver face the opening by a sliver pulling mechanism. .

〓Operation〓 Since the spinning device of this invention has the arrangement of the can with respect to the spinning machine as described above, the sliver pulled out from the can placed on the upper floor is held by the sliver end by the sliver pulling mechanism of the sliver conveying device. It faces an opening provided in the floor surface of the upper floor, and is supplied through the opening to a spinning unit of a spinning machine arranged on the lower floor.

〓Example〓 The spinning device of this invention will be described below with reference to the drawings, taking as an example a spinning machine equipped with each section for stretching, false twisting, and winding as a spinning unit.

and sliver guide roller 21a on shaft 17
and a can 22a on the shaft 20 and a position corresponding to the sliver guide roller 21b, respectively.
As a result, the space between the cans 22a and 22b arranged in two rows forms a working passage 23.

Therefore, workers on the upper floor have traditionally
Slivers 24a, 24b were pulled out from 2a, 22b, suspended on sliver guide rollers 21a, 21b of a sliver conveying device 14, and the tips of the slivers were exposed to the opening 12 of the upper floor 11. However, when using this method, the work must be carried out one by one. Therefore, it is appropriate to divide the spinning units 9 on the spinning machine 1 into a plurality of groups, provide a sliver conveying device 14 for each group, and draw out the sliver for each groove. A sliver conveying device 14 is shown in which units are grouped into one group and configured accordingly.
