Abstract

PURPOSE:To enable the operation of all the machines of succeeding steps except for the failure machines in a number of succeeding step machines, by placing a closed-loop bobbin transfer path between machines of preceding step and those of succeeding step and providing the loop path with a bobbin exchanger for exchanging full bobbin with empty bobbin. CONSTITUTION:A closed-loop bobbin-transfer path 3 is placed between a preceding step machine 14 such as fine spinning frame and a succeeding step machine 15 such as winder. A bobbin exchanger 16 for removing a full bobbin and mounting an empty bobbin is placed at a proper position of the transfer path 3. When a certain kind of machine in a number of winders 15 is out of order, the full bobbin to be transferred to that kind of winder 15 is removed by the bobbin exchanger 16 and an empty bobbin is mounted to the winder to enable the continuous operation of the other kinds of winders 15.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to the transportation of both empty and full bobbins between a front-process machine such as a spinning frame and a next-process machine such as a winder.

(Prior Art) In the past, a tube yarn produced by a spinning machine, that is, a full bobbin, was manually conveyed to a winder and finished into a product (cheese) by the machine. Recently, with the advent of tube changing machines that automatically remove full bobbins from the spindle rows of spinning machines, complex tube changing operations have become mechanized, and carts or conveyors are also used to transfer both air-conditioning bobbins. It is mechanized.

However, when we consider the mode of transport, we find that it is still a bulk transport of one spinning frame car, which is a far cry from the control of individual spindles, where each spindle is subject to management.

In Japanese Patent Application No. 100469/1982 (Japanese Patent Application Laid-Open No. 25189/1989), one of the applicants of the present invention proposed a bobbin conveying method suitable for separate spindle management. The invention described in the above proposal is not only useful in the field of synthetic fibers where the pirn weight is extremely heavy;
Even in the spinning field where the full bobbin weight is light, the spinning machine is a bobbin conveying method that meets the production pattern of small lots and a wide variety of products.
Auctions are often used in winders, and many related inventions have been proposed, such as in Japanese Patent Laid-Open No. 58-59167.

The transportation method between the spinning machine and the winder is shown in Figures 2 and 3.
To explain in detail with reference to the figure, the full bobbin (1) of the spinning mechanism is equipped with a tray (2) equipped with pegs as shown in Figure 2.
) are carried and transported one by one.

Thus, the M-age tray (2) is moved in the direction of the arrow in Fig. 3 by the main conveyor (3) connected to the spinning machine (not shown), but there is nothing on the main conveyor (3) to send it to the A-winder (4). Tray A (6) loaded with A 82 bobbin (5)
) and the B full bobbin (8) sent to the B'74 under (7).
) and the C tray opening loaded with C full bobbins to be sent to C winder Q0 are moving together, and the marks marked on tray (2), such as the tray The thickness, detection grooves, etc. are configured by category, and this is used as a sensor (
(not shown), the required branched conhair Q3 winder (2) is introduced so that it arrives at the required winder (problem to be solved by the invention). Normally, the conveyance path is configured in a closed loop, and if both the spinning machine that produces full bobbins and the winder that consumes them are operating normally, problems with spindle management and small-lot, high-mix production will be solved as described above. can be achieved in time.

However, with this conveyance method, certain winders, such as A
When winder (4) stopped, the supply and demand relationship of the entire system collapsed, and the spinning machine itself that corresponded to A-winder (4) had to be stopped as well. The present invention aims to eliminate such disadvantages that exist in the above-mentioned conveyance method.

(Means for Solving the Problems) The present invention has the following configuration to achieve the above object. In other words, a large number of independent carriers that support individual bobbins are circulated in a closed-loop conveyance path that connects a front-process machine such as a spinning frame and a next-process machine such as a winder, thereby transferring both empty and full bobbins between the front and rear processes. In the bobbin conveyance method to be carried out, a bobbin exchange device is installed at an appropriate position on the conveyance path of the independent carrier from the next process machine to the previous process machine, and this removes a full bobbin from the independent carrier and transfers it to the carrier. It is designed to insert an empty bobbin.

(Function) In the known bobbin conveying method, the present invention extracts a full bobbin loaded on an independent carrier, that is, a tray, on the way from the next process machine to the previous process machine, and then inserts an empty bobbin therein. Therefore, even if a particular next-processing machine stops and becomes impossible to consume full bobbins, the supply and demand balance of the entire system will not be disrupted, and only empty bobbins can be replenished and full bobbins stored. The method of the present invention will be explained in detail with reference to the example shown in the figure below.1. (Example) In Figure 1, there are a plurality of α 8) ring spinning machines, (to) the corresponding winder, and (3) the closed-loop main conveyor that connects the two.

The full bobbin (1) formed by the spinning machine α4 is transferred to the winder (
However, by specifying in advance the winder (g) to which the tray (2) follows and the spinning frame a4 from which the flow returns, the overall supply and demand balance is maintained as described above.

αQ indicates a bobbin changing device which is the core of the present invention, and as shown in the figure, it is installed near the main conveyor (3) from the winder to the spinning machine 04. The full bobbin removal gutter groove and the empty bobbin insertion mechanism built into the device αQ are known mechanisms, for example, Japanese Patent Publication No. 46-8701 for the former.
The tip extraction device described in Japanese Patent No. 5 can be used, and the tip insertion mechanism of a single-spindle doffing device can be used for the latter.

The present invention is carried out using the device as described above, and there is no need to operate the bobbin exchange device α0 under normal operating conditions. All the trays (2) passing near the exchanging device QQ have empty bobbins, and no full bobbins flow into the spinning machine α→ side.

When the winder (A) stops, the bobbin exchange device αQ
is operated to extract the unprocessed yarn, that is, the skin bobbin, on the passing tray (2), insert an empty bobbin into it, and cause the bobbin changing device aQ to perform the same process as a winder in terms of bobbin supply and demand.

At this time, supply of empty bobbins that match the predetermined tray,
Naturally, it is necessary to store the full bobbins that have been pulled out.

(Effects of the invention) In the conventional method in which an independent carrier supporting a single bobbin is circulated on a closed-loop conveyance path to connect the previous and succeeding processes, a spare machine stand is installed as a countermeasure against the stoppage of the next process machine. Only two effective methods have been found: to stop the machine or to actively stop the front-end machine, but by implementing the method of the present invention, countermeasures against machine stoppage can be easily implemented.
