Description

[Detailed description of the invention] Industrial field of application The present application relates to a method of transporting roving bobbins between a roving frame and a fine spinning machine, which are connected by a transport means such as a transport rail, and is compatible with larger machines. At the same time, it aims to streamline continuous unmanned work.

Conventional technology and its problems In recent years, unmanned operation has become widespread due to labor-saving measures, and conveyance means such as transfer rails are installed between the roving frame and the spinning frame, and the doffing from the roving frame is carried out by this conveyance means. Full roving bobbins (hereinafter referred to as full bobbins) and empty bobbins from spinning machines are also transported automatically.

However, as is well known, a roving frame has a much smaller number of spindles than a spinning frame, and therefore a full bobbin unloaded from a roving frame may not be enough to carry out four conversions. When transporting full bobbins, it is difficult to sort them, and this tendency is further exacerbated with the multi-spindle long spinning machines that have been used in recent years. Means for Solving the Problems In view of the above, the present application sets the ratio of the number of spindles between the roving frame and the fine spinning frame to 8, and transfers two full bobbins doffed from the roving frame to the fine spinning frame. By conveying, a full bobbin necessary for one bobbin exchange (four exchanges) is conveyed.

EXAMPLES Next, the method of the present invention will be explained in detail with reference to drawings showing examples. In the drawing, RM is a roving frame, and the roving frame is the largest multi-spindle machine that can be manufactured at present in order to improve productivity.
Adopts a machine with 20 spindles.

Next, spinning machine SF1. SF2 is made to correspond to the roving frame RM, and has 960 spindles so that 4 exchanges of all the spindles can be performed with the eight balls i (hereinafter referred to as docks) of the roving frame RM.
The ratio of the number of spindles between M and spinning machines SFI and SF2 is 1:8
It becomes. As is well known, the spinning machines SFI and SF2 are equipped with a bobbin creel 1 on the top surface of the machine, and as shown in FIG. The bobbin row 3 in the - row is suspended from the bobbin hanger 5, and 4 conversions are performed as one work unit.
In the case of the present application, since there are 960 spindles, 240 full bobbins 2 for 240 spindles are suspended in one row, that is, 240 full bobbins 2 for two docks of the roving frame RM are suspended.

6 is 1. ffl spinning machine RM and spinning machine SF1. A conveying means arranged between the SF2, the main rail 7 and the dotting rail 8 which branches from the main rail and reaches the front of the spinning frame RM, and the dotting rail 8 which also branches from the main rail 7 and reaches the front of the spinning frame S.
It consists of a spare rail 9 located on the R and L sides of FI and SF2, and a bypass rail 10 that bypasses between the main rails 7 and is provided with automatic residue removal devices A, R, and S approximately in the middle thereof. Each of the rails is elevated and held at a predetermined height above the ground. Further, the above-mentioned transfer means 6 has an open circuit as a whole, so that the single main rail 7 can transfer full and empty bobbins 2.4. The full and empty bobbins 2.4 conveyed through the conveyance means 6 are one conveyance unit for one dock, and the bobbins of the bobbin carriage 11 shown in Japanese Patent Application Laid-Open No. 60-67368 previously filed by the present applicant are The conveyor is suspended from a hanger 5, and a drive device f12 is provided to move the conveyor such as a bobbin carriage along the conveyor means 6, and a drive device f12 is provided at a branch point of each rail to move the conveyor to a predetermined position. The switching device 13, etc., which switches the branching point to convey in the direction of As long as it is a unit and can be transported between fine and roving frames in a predetermined order, it can be appropriately selected from conventionally known ones.

Next, we will explain the transport cycle of full and empty bobbins 2.4 in the present application.6 It goes without saying that in the present application, multiple roving frames and multiple spinning frames are connected at a predetermined ratio to carry out work. I will do it.

In the detailed explanation of the conveyance cycle below, the smallest combination unit, the roving frame RM, is used for one spinning frame SFI.
, SF2 describes a combination of two units.

The conveyance of full and empty bobbins 2.4 by the conveyance means 6 is a continuous operation and the situation changes constantly, but as a reference for explanation, the spare rail 9 of the spinning frame SF2 in the figure is empty and the full bobbin 2.4 is conveyed in an empty state.
An empty bobbin 4 (an unprocessed bobbin with residual yarn wound around it) is suspended from the spare rail 9 of the spinning machine SF1.
The explanation begins with the bobbin carriage 11 being installed and requesting to take over the empty bobbin 4, and the bobbin carriage 11 with a full bobbin 4 suspended from the dotting rail 8 of the roving frame RM waiting. .

Request to pick up 4 empty bobbins from spinning machine SFI and spinning machine SF2
In response to a request for full bobbins, one bobbin carriage in which 120 empty bobbins 4 located on the main rail 7 side of the R-side bobbin carriage 11 of the spinning frame SFI are hung (corresponding to the number of spindles of the roving frame) The storage 11 is transported. This bobbin carriage 11 enters the bypass rail 10 from the spare rail 9 via the main rail 7, reaches A, R, and S, and starts stripping off the remaining yarn. Next, the bobbin carriage 11 suspending the full bobbin 4 and waiting on the dotting rail 8,
It is transported from the dotsfin rail 8 to the main rail 7,
The bobbin 2 is sent to the spare rail 9 on the R side of the spinning frame SF2, which is requesting a full bobbin 2.

During this time, residual yarn processing is performed by A, R, and S, and 120
When the processing of all the weights is completed, the bobbin carriage 11 suspending them passes through the bypass rail 10 and the remaining rail 7, and enters the dotting rail 8, and when the bobbin of the roving frame RM becomes full bobbin 2, the bobbin carriage 11 suspends the weight. The empty bobbin 2.4 is exchanged, that is, the doffing machine is carried out, and the full bobbin 2 is now suspended in the bobbin carriage 11, which had previously suspended the empty bobbin 4, and the state is the same as that at the start. Become. In this state, the spinning machines SF2 and SFI are still making full bobbin requests and empty bobbin take-back requests, so they take over the empty bobbin 4 from the spinning machine SFI in the same order as described above. By supplying full bobbins 2 to the spinning frame SF2 and repeating this four times in succession, all the empty bobbins 4 are taken up from the spare rail 9 of the spinning frame SFI, and the empty bobbins 4 are transferred to the spare rail 9 of the spinning frame SF2.
240 bobbins per side and 4SO0 full bobbins 2 are supplied to replace the bobbins. As mentioned above, in this application, the Rover RM
By setting the number of spindles between the spinning frame SFI and SF2 at a ratio of 1 = 8, it is possible to make 4 exchanges on one side with 2 full bobbins for 2 doffs unloaded from the roving frame RM. .

In the above embodiment, 120 full and empty bobbins 2 and 4 are transported at one time. The weight may be conveyed at one time, and in actual practice, taking into account the capabilities of the roving frame and fine spinning frame, more machines are connected, and each machine is controlled by a predetermined control means to carry out the above-mentioned conveyance. However, since this is not the gist of the present application, its explanation will be omitted. In the above example, the ratio of the number of weights is 1:8, which is 120:960 weights,
If the roving frame has 100 spindles, the spinning frame has 800 spindles and 100 spindles:
There will be 800 spindles, and 7,100 per door.

Effects of the Invention As detailed above, the present invention has been developed to meet the current manufacturing limit of 1.
Compatible with a large roving frame with 20 spindles, the roving frame is equipped with a multi-spindle stand with 960 spindles, and the ratio of the number of spindles is set to 8. This allows for one full bobbin of 2 doffs on the roving frame to convert 4 times. This makes it possible to streamline the work.
