Description

[Detailed description of the invention]

r Industrial Field of Application Σ The present invention relates to a device for suctioning air and supplying compressed air necessary for a yarn #Ig placement and doffing device in a spinning machine. [Prior Art] A yarn splicing device, a doffing device, etc., which are supported by a guide member such as a guide rail provided over a plurality of rows of spinning units and move along the 1175 rows of spinning units, are installed. Only one work trolley is installed on each spinning machine stand so that it can be moved in the longitudinal direction of the machine stand, and when a spinning unit that requires them is moved, it is moved there for splicing or splicing. Make fried eggs. The yarn piecing and doffing operations carried out by these work carts (as is well known, are often performed using air suction or blowing out compressed air, but the above-mentioned methods are used to obtain the compressed air, etc. necessary for the work). The blower, etc. may have been placed on the work cart, or because the work cart is large in weight and shape, the blower, etc. may have been installed at the end of each spinning machine, and the valved end of the piping from these should be connected to each spinning machine. It is provided for each unit, and at the location of the spinning unit that has moved and stopped due to the need for work, the work trolley side support connects its mouth to the piping terminal and opens the valve to suck air and supply compressed air. The conventional air supply system as described above for the spinning machine work cart consists of WI complicated piping on the spinning machine body side and a terminal with an automatic on-off valve for each spinning unit. Not only does it require
A mechanism for connecting the pipes is also required on the work trolley side, and the overall mechanism is W! It was too sloppy, and there was a risk that problems would occur due to connection errors. K Problems to be Solved by the Invention] In view of the above points, the present invention aims to provide a simpler and more reliable air supply system to the work cart of a spinning machine, and also to reduce the weight of the work cart. purpose. Means for Solving Problem K] The present invention provides a work cart supported by a guide member provided along a row of spinning units arranged in parallel, and on which a yarn splicing device is mounted, and a work cart mounted at an end of the row of spinning units. A hose protected by a bendable protective device was directly connected to the installed pressure reduction device.

[For production]

By constantly connecting a work cart that moves on a guide member such as a guide rail to the pressure adjustment device of the blower, which is an air pressure Fi equipment installed on the machine side, with a hose for supplying air,
The piping on the spinning machine main body side and the piping connection mechanism on the work cart side are no longer required, and there is no need to reconnect the air supply piping every time the stopping position of the work cart relative to the spinning unit is changed. Furthermore, the weight of the work cart can be reduced to enable quick movement. Example: An example of the implementation of the device of the present invention will be described below with reference to the drawings. A plurality of spinning units 1 are arranged in a row between a gear 1 and an out-end box 3 at both ends, and are supported by a guide member 4 such as a guide rail along the row of spinning units 1, and a yarn splicing device and a doffing device are installed. A spinning device 6 is constituted by a work trolley 5 on which a g station (not shown) is placed so as to move back and forth. Inside the out end box 3, there is a thread splicer g@ of the work cart 5.
A blower 7 for generating suction airflow and an air compressor 8 for blowing out compressed air are provided for operations such as the following. The blower 7 has a dust box 9, and the air F:i compressor 8 has a compressed air tank 10. And the dust box 9. The compressed air tank 10 and the work trolley 5 are connected to each other by flexible air guide pipes 11.1.
Connect with 2. The air conduit 11.12 is shown enlarged in FIG.
It is held together by a flexible protector 13, one end of which is fixed to the frame of the work cart 5 by a movable end fitting 14, and the other end is fixed to the frame of the work cart 5 by a fixed end fitting 15. It is fixed to the out end hox 3 of. As shown in a plan view in FIG. 3, the flexible protector 13 is made by connecting a large number of links 16 with pins 17, and integrating two of them at regular intervals using supports 18 to form a bendable chain shape. This is what I did. The supporter 18 has an opening 19 (see Fig. 4) through which the air guide tubes 11 and 12 are inserted.
To enable the air guide pipe to be dragged together with a work cart 5 without applying excessive force. During operation of the spinning device 6, the blower 7 and the air compressor 8
is operated, and the valve 20 of the compressed air tank 10 is also opened so that the sudden suction through the air guide pipe 11 and the compressed air supply through the air guide pipe 12 reach the work cart 5 at all times. When the work cart 5 moves for thread splicing or doffing,
Two air guide tubes 11 and 12 held by the flexible protector 13
Move while refracting. During movement, the force with which the work trolley 5 pulls the air guide tube 2 moves mostly against the flexible protector 13 whose end is fixed to the work trolley 1. Furthermore, as the work cart 5 moves, the bending point A of the flexible air guide tube 11, 12 also moves, but the radius of curvature of the bending point is always kept at the maximum by the chain-shaped flexible protector 13, so that Two hoses are not forced to bend. Therefore, the work trolley 5
Even if you move frequently and drag the air guide pipes 11 and 12, there is no risk of damage to the hose in a short period of time. When the work trolley 5 is at the stop position, necessary valves are opened to perform work while receiving air supply. In the above embodiment, a cable carrier was used as a flexible protector for the hose, but in this defense, the protector is not limited to a cable carrier, and like a cable carrier, the hose can be easily bent without applying excessive force. Anything that can protect the hose so that it can be routed is fine. Also, as is clear from Figure 1, only the tip end 172 of the hose is routed as the work cart moves, and the remaining 1/2 of the fixed end is not moved. The use of protective equipment can be omitted. K Effects of the invention] The present invention, as shown in above) E, directly connects the pressurizing and depressurizing device installed at the end of the machine and the work trolley with a hose protected by a bendable protector, so that the work trolley can operate as described above. Since the hose is bent and moved to receive the air suction and pressurized air necessary for work, there is no need for piping on the spinning machine main body side and a piping connection mechanism on the work trolley side, which makes it easier to operate the work trolley each time the position of the work trolley is changed. There is no need to actuate the connection mechanism and reconnect the air supply piping, and as a whole, a significant reduction in R-lateral portions is achieved. Furthermore, the weight of the work trolley is reduced due to a reduction in the number of parts, making it possible to increase the traveling speed during transport, shorten the time required for acceleration and deceleration, etc., and improve the operating efficiency of the spinning TFA machine. be done.
