CONSTITUTION:A roving carrying dolly 4 is arranged with creel dollies 40 and 40' vertically in two stages, and the lower creel dolly 40' is suspended movably and separatably from the upper creel dolly 40 via a coalescing rail 30. 20 bundles (5 bundles X 4 rows) of rovings 10 can be held by one creel dolly 40 as shown in the figure, 40 bundles of rovings 10 in all can be carried in package by a dolly bed, as a result, roving creels corresponding to 20 spindles on one face, or 40 spindles on both faces, are formed on a spinning frame with a two-face structure. The roving fitting and the pick finding of rovings 10 performed while both creel dollies 40 and 40' are separated can be easily performed, and very high-density roving creels are obtained when both of them are combined. The roving exchange time for the simultaneous exchange of rovings 10 is shortened, and the number of exchanges for large-package rovings is reduced.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a spinning machine that runs while being suspended from an overhead rail that connects the vicinity of a front spinning frame and a plurality of spinning machines, and carries a roving supply creel on top of a spinning frame. This invention relates to a roving carriage that is immediately formed.

(Prior art) The operating method uses a cart suspended on an overhead rail to transport the roving, thereby immediately forming a supply creel, which reduces the time required for changing the roving as the roving is replaced all at once. , which in turn improves the operating efficiency of the spinning machine as a whole (reducing downtime for changing roving, improving machine productivity)
This is an extremely advantageous mode of operation in that it leads to

On the other hand, from the perspective of labor saving in the spinning process, it is important to lengthen the roving change interval and reduce the number of times, and efforts have been made to increase the capacity of roving per ball, that is, to create large packages. .

As a roving transport trolley, see Utility Model Publication No. 57-6445.
A reel truck (one-tiered truck that forms one creel on the spinning machine) is used as shown in lJ, and a large number of such trucks equipped with roving are kept on standby to change the roving. If the required spinning frame is not available, the standby trolley is introduced onto the spinning frame and the roving supply creel is installed (only one stage).
was forming.

(Problem to be solved by the invention) However, if the capacity of the roving is increased, the winding diameter also increases (
Therefore, there is a limit to the formation of a roving supply creel within the spacing between the flanges of a spinning machine, and the above-mentioned one-stage reel system has become a bottleneck in large packaging of roving.

SUMMARY OF THE INVENTION An object of the present invention is to provide a roving transport cart that can realize large packaging of roving by taking advantage of the conventional method of exchanging roving all at once (criel exchange).

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration. That is, it is a roving transport cart that runs suspended from an overhead rail that connects the vicinity of the front spinning machine and a plurality of spinning machines, and immediately forms a roving supply creel on the spinning machine, and has wheels on its upper end. The bobbin holder is comprised of a support device that movably suspends the entire cart, a support plate that is fixed to the support plate, and a plurality of bobbin holders that are arranged on the lower surface of the support plate and that suspend and support the roving. Creel carts are arranged in two stages, upper and lower, and the upper creel cart is provided with a combining rail for suspending the lower creel cart, and the lower creel cart is connected to the upper creel cart via the combining rail. It is characterized by being suspended so that it can be moved and separated.

(Function) According to the configuration of the present invention, since the creel cart is stacked in two layers, upper and lower, it is possible to install roving yarn with a total capacity twice that of the conventional one.
When installing the same number of rovings on the entire cart as before, the capacity per ball of roving is twice as large, and the length is twice as long (twice the weight).
It is possible to create large packages up to.

In addition, the lower creel cart is movably suspended from the upper creel cart, and the upper and lower sections are configured to be separable. On the other hand, combining the two creates a very high-density roving creel, and if this is run as a roving transport cart with the top and bottom stacked in two layers, it can be easily pulled out on the spinning machine where the roving is to be changed. A two-stage roving feeding creel can be immediately formed.

Therefore, according to the present invention, it is possible to shorten the roving change time by changing the rovings all at once (to improve the operating efficiency of the spinning machine), and to reduce the number of roving changes by making large packages of the rovings (to improve the spinning machine operating efficiency). Both of these can be achieved (labor saving in the process).

Furthermore, the roving loading cart waiting area (6) is connected to the spinning machine (2) from the roving loading area (5) of the overhead rail fil.
It is formed by branching off from the middle of the route leading to the roving, and is used to transport the roving transport cart (4) loaded with full roving in preparation for changing the roving on the spinning machine (2). This is the waiting area. As mentioned above, if the roving is loaded and the empty bobbin is attached and removed within the time required for changing the roving, this roving loading cart waiting area (6) can be used as storage for one creel-simultaneous change. It is sufficient to have enough space to wait for 10 m-thread and i-carriers (4) required to form a creel for one spinning machine.

The roving carriage (4) suspended from the overhead rail (3) moves along the arrows shown in Fig. 2 (outward route: solid line, return route: broken line).
3) A switching device (not shown) is installed at the upper branching point and confluence point so that the roving transport cart (4) can run smoothly and safely.
Appropriate measures are being taken, such as the installation of In addition, a stopper (not shown) is provided at the creel section on each spinning frame (2) of the overhead rail (3) and at the end of the roving loading cart waiting area (6). Consideration has been taken in terms of operation and safety, such as ensuring the appropriate position of each spinning machine for thread (1).

The roving feeding device according to this embodiment has the above-mentioned configuration, and its usage will now be explained.

The roving (10) obtained from the front spinning machine (1) is conveyed to the roving attachment area (6) by an appropriate means such as a belt conveyor (not shown), and then the roving attachment area (6) as described above is transferred to the roving attachment area (6). Using this method, a total of 40 balls are attached to the roving carriage (4) in two batches of 20 balls each.Once the roving carriage (4) has been attached, it is pulled forward from the roving attachment area (5). The roving transport trolley (4) has now finished attaching (removing) the empty bobbin.

At this time, the overhead rail (
3) Return route above (route indicated by the dashed arrow in Figure 2)
Although it depends on the usage status (crowding) and the weight of the loaded roving (10) (the weight of the entire roving loading cart), in this embodiment, each roving cart is run one by one.

If a spinning frame (2) has completed its operation for a predetermined period of time, that is, a spinning frame whose bobbin is empty after the feeding of a prescribed length of roving has been completed, the roving transport trolley is removed from the spinning frame (2). (4) in order and run it along the return path (broken line arrow) shown in Figure 2 to the empty bobbin removal area (7), where the empty bobbin is removed using the empty bobbin removal means Q■ as described above. This is to attach/detach (remove).

In this way, when more than 10 empty roving transport carts (4) have been pulled out from the spinning machine (2) that requires new roving (Go), the roving carts (4) are pulled out from the above-mentioned roving loading cart waiting area (6). Pull out the roving transport cart (4) loaded with 0■ of full rovings,
They are carried into the creel section above the spinning frame (2) one after another along the travel route (solid arrow) leading to the spinning frame (2). Once the delivery of 10 roving carts is completed, or 1
Immediately after the roving is installed, the ends (ends n) of each roving (10), which have been completely taken out, are placed in the thread path of each spindle of the spinning frame (2) in the order in which they are brought in one by one, and the operation can be restarted. The various operations from the start of pulling out the empty roving transport cart (4) to the completion of splicing of all the spindles of the spinning frame (2) are called "roving change". After this, the spinning machine (2
) resume operation.

By repeating the operations described above, all (1 in this example)
Formation and replacement of roving supply creels for six (6) spinning frames (2) are carried out using one roving loading cart waiting area (6), which has the roving storage capacity of one spinning frame, as a waiting area.
Since this can be achieved simply by using series, it saves space and allows effective use of the remaining site space.

The operation start (resumption) time of each spinning frame (2) is programmed in advance so as not to overlap, taking into consideration the size of the supplied roving (1) (that is, the winding length of the roving). There is.

Regarding the running system of the trolley, in this embodiment, the roving transport trolley (4) is manually pulled using an appropriate jig, but a self-propelled trolley with a built-in drive source,
It may be a chain running type trolley or the like.

In the present invention, unless otherwise specified, "roving" refers to
It refers to the roving wound around a bobbin, and is used in this sense throughout the text.

(Effects of the Invention) According to the configuration of the present invention, since the creel cart is stacked in two layers, upper and lower, it is possible to install roving yarn with a total capacity twice that of the conventional one.
When the same number of rovings are attached to the entire cart as before, the capacity per ball of roving can be doubled, and large packages up to twice the length (double the weight) can be achieved.

In addition, the lower creel cart is movably suspended from the upper creel cart, and the upper and lower sections are configured to be separable. On the other hand, combining the two creates a very high-density roving creel, and if this is run as a roving transport cart with the top and bottom stacked in two layers, it can be easily pulled out on the spinning machine where the roving is to be changed. A two-stage roving feeding creel can be immediately formed.

Therefore, according to the present invention, it is possible to shorten the roving change time by exchanging the rovings all at once (improving spinning machine operating efficiency), and reduce the number of roving changes by large-packaging the rovings (improving the spinning process). Labor saving) can be achieved.
