Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a conveyance path for roving bobbins installed between a spinning frame and a roving frame, and a conveyance path for roving bobbins installed between a spinning frame and a roving frame. The roving bobbin is effectively transported by an open-circuit transport path consisting of a spare rail and a dotting rail that branch out at the same time as the main line, and a bypass rail that is further equipped with an automatic residue stripping device.

Conventional technology and its problems In recent years, the automation of spinning machines has progressed, and the roving bobbin, which is automatically doffed by the roving machine, is transported to the spinning machine via a predetermined conveyance path, and the spinning machine automatically exchanges the yarn. The empty bobbin taken out from the spinning machine is conveyed to the roving frame, and automatic continuous operation is widely carried out.
In addition, many conveyance tools have been proposed that run on the conveyance path and convey the roving bobbin, and the present applicant also previously proposed Japanese Patent Application Laid-Open No. 60-673.
No. 68 "Roving bobbin conveying device" has been filed.

Considering the conveyance route consisting of the main and branch rails of the device related to the above application, the main rail and the branch rails branching from it are all open circuits, and the cycle time is extended by the circular route. , the overall length of the rails becomes longer due to the use of two main rails for the outbound and return trips, and the complexity of the control is eliminated. However, with the above-mentioned conventional device, the next operation cannot be performed at all from the time the conveyor starts until it completely reaches the goal, such as when the conveyor from the spinning frame is transferred to the roving frame and vice versa. There is a loss in time, and this loss cannot be ignored as the main rail length increases. Furthermore, in the conventional device described above, the process of processing the remaining yarn, which takes the longest time during the cycle time, that is, the process of automatically stripping off the yarn remaining on the empty bobbin, is not carried out on the main rail 2, which further extends the cycle time. It has its drawbacks.

Means for Solving the Problems In view of the above-mentioned conventional devices, the present application provides automatic residue stripping devices (hereinafter referred to as A, R, and S) on the main rails from spinning machines to roving machines.
A bypass rail is installed to bypass the empty bobbins taken from the spinning frame to dispose of the remaining yarn, and also to act as a kind of gluing rail.During this time, the full bobbins doffed by the roving frame are transferred to the spinning frame. This eliminates the drawbacks of the conventional device described above.

The holding plate 11 is held in the width direction by the bobbin carriage 15.
This transfer device 16
is configured to rotate forward and backward by a drive device (not shown).

Next, a switching device 34 is attached to each branch point of the preliminary doffing and bypass rails 102 and 1.03104 branching from the main rail 101 to control the operation of the bobbin carriage 15.

Although the R, L, or lower direction of this switching device 34 is reversed in the drawings depending on its mounting position, the configuration and function are the same, so only the one mounted on the spinning machines SF1, SF2, and SFn will be explained. .

As shown in FIG. 7, this switching device 34 on the spinning machine side swings horizontally around a support shaft 38 that is vertically supported at the branch point between the main rail 101 and the spare rail 102 on the spinning machine side. An air cylinder 41 is connected to the tip of a swinging arm 40 attached to the upper end of the support shaft 38, and a connecting rod 42 is connected to the middle part of the swinging arm 40 with a pin.

The functions of the embodiments of the present invention constructed as described above will be explained below, but in two or more embodiments, the structures of the bobbin carriage 15, the transfer device 16, the switching device 34, etc., other than the structure of the conveyance path 100, were all made by the present applicant. The structure of Japanese Patent Application Laid-Open No. 60-67368, which was previously filed by JP-A-60-67368, is adopted. However, in the present application, these configurations are not limited to the above, and any conventionally known configurations may be used as long as the roving bobbin of the conveying unit can be conveyed between the fine and roving frames as detailed below. Any device may be used and its configuration does not matter.

The conveyance of the roving bobbin by the conveyance path 100 is a continuous operation and the situation always changes, but as a reference for explanation, the spare rail 102 of the spinning frame SFI in the figure is empty fm and full bobbin F.
A bobbin carriage 15 is mounted on the spare rail of the spinning frame SF2 and the bobbin carriage 15 suspends the empty bobbin EB (unprocessed with residual yarn wound around it) and takes over the empty bobbin. In addition, the bobbin carriage 15 with full bobbins FB suspended from the dotting rail 103 of the roving frame RMI (RM2 is also acceptable) is waiting, that is, the roving frame and the spinning frame are 1. The explanation will be based on the correspondence of =2.

In response to a full bobbin FB request from spinning frame SFI and a take-over request from spinning frame SF2, the bobbin carriages 15 on the R side of spinning frames S and F2 start to be transported by the action of the transfer device 16, and at this time, the bobbin carriages 15 on the R side of spinning frames S and F2 start to be conveyed. Spare rail 102 on the R side
All of the switching devices 34 from the branching point of the bypass rail 104 to the branching point of the bypass rail 104
5 to the bypass rail 104, and the main rail 101 during this time is entirely open. Therefore, the bobbin carriage 15 hanging the empty bobbin EB is sequentially relayed to the transfer device 16 provided on the way, enters the bypass rail 104, reaches A, R, and S, where the remaining yarn is processed and completely processed. When finished, bobbin carriage 15
moves to the right side of A, R, and S in Fig. 1, but since the bypass rail 104 is set to the above-mentioned dimensions, it does not protrude onto the main rail 101 and obstruct other conveyance regardless of whether before or after residual yarn processing. There is no.

As described above, when the bobbin carriage 15 with the empty bobbin EB suspended from the R side of the spinning frame SF2 starts and reaches A, R, and S, it first moves to the dotting rail 103 of the spinning frame RMI.
Bobbin carriage 15 with full bobbin FB hanging there, which was waiting at the top, first issued a full bobbin request in spinning machine SF.
It faces the spare rail 102 on the R side of I, and is sequentially relayed to the transfer device 16 provided on the way as described above to carry out the transfer, and all the switching devices 34 provided at this special number branch point are connected to the main rail 101. The bobbin carriage 15 that has been opened and started from the roving frame RM1 is transported so as to be guided to the spare rail 102 on the R side of the spinning frame SFI. During this time, A
Remaining yarn processing is performed by R and S, and when all processing is completed, the bobbin carriage 15 suspends the processed empty bobbin EB.
exits the bypass rail 104 and is conveyed to the dotting rail 103 of the roving frame RMI, but naturally at this time the switching device 34 opens the main rail 101 between the bypass rail 104 and the dotting rail 103 of the roving frame RMI. It is working to do so.

With the above, the supply of full bobbins FB to the R side of spinning machines SFI and SF2, and the taking back of empty bobbins EB, have been completed.
When the bobbin carriage 15 on which doffing is performed on the roving frame RM2 and a full bobbin FB is suspended is waiting on the doffing rail 103 of the roving frame RM2 (in this case, the winding speed of the roving frame is set to the roving speed of the spinning frame). It is much faster than the usage speed of R.
Even if the roving frame RMI does not use M2 until it performs the next doffing, it is sufficient in terms of capacity. ).

In the same order as above, take the empty bobbin EB from the L side of the spinning frame SF2, and transfer the full bobbin F to the L side of the spinning frame SFI.
B is supplied, and the -cycle conveyance work is completed. Then, in the spinning machine SFI to which the full bobbin FB was supplied, a replacement is performed, and the empty bobbin EB is transferred to the spare rail 10.
When the bobbin is taken out onto the bobbin 2, the spinning machine SFI issues an empty bobbin take-up request, and the spinning frame SF2 issues a full bobbin request, conversely to the above, and the full bobbin is taken and supplied.

Next, the dotting rail 103 of the roving machine RMI, RM2
I will explain about it. Dotfin rail 1 in the drawing
03 branches from the main rail 101, passes through the rear side of the roving frame, bends into a U-shape, and reaches the front of the machine frame. , the empty bobbins EB carried by the bobbin carriage 15 are transferred to the simultaneous transfer device by the lifter, and - when the simultaneous transfer device attaches the full bobbins FB taken out from the roving frame to the bobbin hanger 12 of the bobbin carriage 15. In the case of a wagon-type group lift, it is only necessary to branch out so that it is located directly in front of the machine.

In the above description of the embodiment, the roving frame and the fine spinning frame are 1=2.
Although we have explained the minimum unit of work that corresponds to the ratio of Although the work is controlled by means, this is not the gist of the present application and will therefore be omitted.

Next, another embodiment shown in FIG. 8 will be described. In the embodiment shown in FIG. 8, a storage rail 104a is provided parallel to the bypass rail 104, and an empty bobbin EB that has been processed with residual yarn is placed on standby on this rail, and an empty bobbin EB taken from the spinning frame SF as described above is placed on standby. EB is bypass rail 1
04, when the full bobbin FB is started from the roving frame RM, the empty bobbin EB waiting on the storage rail 104a is sent to the roving frame without waiting for the remaining yarn processing of the empty bobbin EB on the bypass rail 104. As a result, cycle time can be shortened.

Furthermore, in the above embodiment, the bypass rail 104 and the AR8
Although there is only one set of these, by providing multiple sets, it is possible not only to shorten the cycle time, but also to transfer empty bobbins taken from a specific spinning machine to a specific bypass rail when spinning products using different raw cotton. After conveying the yarn to a machine and processing the remaining yarn, the empty bobbin is sent to a specific roving frame, and then the full bobbin is sent from the roving frame to a specific spinning frame, thereby improving quality in the case of high-mix, low-volume production. To facilitate management and increase the utilization of stripped yarn.

Effects of the Invention As described in detail above, the present application has a simple structure in which a spare rail and a dosing rail are branched from one main rail, a bypass rail is provided, and the entire conveyance path is open, so that full and empty bobbins can be handled easily. Not only can the conveyance efficiency be greatly improved, but also
This is an extremely significant invention that contributes to automated work by eliminating the shortcomings of conventional equipment, such as making it possible to transport large-scale spinning and spinning machines between groups at low equipment costs, and responding to the diversification of manufactured products. It is.
