Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a spinning bobbin conveying device for conveying spinning bobbins between an automatic winder and a spinning machine.

[Prior Art] Generally, in factories that employ a system that connects an automatic winder and a spinning machine, a spinning bobbin conveying device is installed to transfer the spinning bobbins to each other. ing.

This conveyor is designed to convey trays with spinning bobbins placed on them by a conveyor installed between an automatic winder and a spinning machine, and to convey the actual bobbins produced in the spinning machine. [Problem to be Solved by the Invention 1] However, in recent years, the empty bobbin that has been wound up as a pad gauge in the automatic winder and discharged is transported to the spinning machine. In order to allow workers, trolleys, etc. to pass between the automatic winder and the spinning machine, that is, to cross the conveyor, the conveyor is raised into a gate shape. .

However, in such a gate conveyor, the bend in the section where the direction changes is made gentle so that the spinning bobbins of the trays conveyed in a row do not interfere with each other and so that the direction can be changed smoothly. This creates an issue in terms of space saving, as this requires a lot of wasted space.

Furthermore, there is a height difference in the bobbin conveying surface between the spinning machine stand and the winder machine stand, and there is also a width difference in the position of the bobbin conveying path, which complicates the route and drive mechanism of the conveyor. For this reason, in addition to increasing equipment costs and complicating maintenance, if the distance between machines is increased or the layout is changed, the transport equipment may need to be changed, such as extending the transport distance or changing the route. The problem was that it was difficult to deal with.

In view of the above-mentioned circumstances, the present invention was devised to provide a spinning bobbin conveying device that can secure a passage in a space-saving manner and can accommodate changes in arrangement with a simple mechanism.

[Means for Solving the Problems] The present invention provides an automatic winder, a spinning machine, etc., in which a tray in which spinning bobbins to be transferred are placed is tilted in the transverse conveyance direction on the outbound and return trips, and An elevating conveyor is provided for conveying the material, and an intermediate conveyor is provided between these elevating conveyors to connect the mutual conveyance routes.

[Operation] With the above configuration, the elevating conveyor changes the attitude of the trays 1 to 1 in a twisting manner, detours them in the vertical direction, conveys the trays in a line with each other, and lowers the other tray via the intermediate conveyor. Pass it to a conveyor or an ascending conveyor to secure a passage space between an automatic winder and a spinning machine.

[Example] Hereinafter, an 8m example of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show an embodiment of a spinning bobbin conveying device according to the present invention, and show a state where it is installed between an automatic winder 1 and a spinning bobbin 1112. FIG.

This conveyance device relays the conveyance between elevating conveyors 3.4 provided in the automatic winder 1 and the spinning machine 2, respectively, in order to convey the tray T in which the spinning bobbin B is inserted. In this embodiment, the transport path is formed in the form of a gate that detours upward.

That is, a rising path 7, which is the outgoing path of the lifting conveyor 3, is connected to the output end of the carrying-out conveyor 6 of the spinning machine 2, and a descending path 9, which is the returning path of the lifting conveyor 4, is connected to the loading end of the loading conveyor 8 of the automatic winder 1. and these lifting conveyors 3.4
An intermediate conveyor 5 is interposed therebetween to form a real bobbin conveyance path 10 for conveying the real bobbin B.

On the other hand, the empty bobbin transport path 11 that transports the empty bobbins B is connected to a rising path 13 that is the outgoing path of the lifting conveyor 4 connected to the discharge end of the discharge conveyor 12 of the automatic winder l, and a spinning machine 2.
It is formed by a descending path 15 which is the return path of the elevating conveyor 3 connected to the incoming end of the incoming conveyor 14, and an intermediate conveyor 5 connecting these.

As shown in FIG. 1, these lifting conveyors 3.4 are connected to carry-out/carry-in conveyors 6.8.12.
14, and the difference between the conveyor dark path ML of the automatic winder 1 and the conveyor dark path MM (M>L) of the spinning machine 2 is eliminated by using the loop path of the intermediate conveyor 5. It has become. Furthermore, as shown in FIG. 2, the difference between the height H of the bobbin conveying surface of the automatic winder l and the height G (H>G) of the bobbin conveying surface of the spinning machine 2 is the difference between the height H of the bobbin conveying surface of the automatic winder 1 and the height G (H>G) of the bobbin conveying surface of the spinning machine 2.
This problem can be solved by changing the overall length and height of 4.

The passage 16 for workers, carts, etc. is located below the intermediate conveyor 5, which is the ceiling part of the gate, and in the space sandwiched between the elevator conveyor 3.4, which is erected in opposition to it.
It will be secured.

Elevating conveyors 3 and 4 are loading/unloading conveyors 6°8.1
2.14 or close to the intermediate conveyor 5, and a vertical portion 18 extending in the vertical direction, which is connected to each other by a smooth curve.

As shown in FIGS. 3 and 4, the elevating conveyor 3.4 engages with a guide plate 19 partitioned to surround the bottom, side, and top of the tray T, respectively, and the bottom of the tray T. It is mainly composed of a conveyor belt 20 that is moved in the conveying direction A by the contact friction force.

The conveyor belt 20 has a side edge 21 serving as a conveying surface, and is shaped such that its width direction always intersects with the conveying direction A. And on the side edge 21 opposite to the conveying surface,
A spring 22 is provided that urges the conveyance surface side.
The conveyor belt 20 is always in contact with the bottom of the tray T.

The springs 22 are arranged at appropriate intervals along the longitudinal direction of the elevating conveyors 3 and 4, and between the springs 22 and the conveyor belt 20, there is a support plate 23 that supports the conveyor belt 20 while transmitting an urging force. is interposed.

Further, at the bottom of the guide plate 19, there is a slit portion 24 that guides the conveyor belt 20 so as to sandwich the conveyor belt 20 therebetween.
4 along the longitudinal direction.

One guide plate and the conveyor belt 20 have a bent portion 25 that smoothly connects the horizontal connecting portion 17 and the vertical portion 18.
, the tray T is formed so as to change its posture.

That is, the lifting conveyor 4 of the automatic winder 1 circle shown in FIG.
In terms of the ascending passage 13, it is formed so as to change direction while being twisted at an angle of 90 degrees with the conveyance direction A as an axis at the bending part 25, and the spinning bobbin B is erected at the horizontal connection part 17. The tray 1', which is in this position, is tilted in the transport transverse direction C at the vertical portion 18, so that the spinning bobbin B is made horizontal.

In this embodiment, the lifting conveyor 3.4 is tilted (twisted) at its upper and lower bent portions 25, and the spinning bobbins B being raised and lowered are arranged to face each other at their vertical portions 18. It is designed to be centered between the two.

As shown in FIG. 5, the intermediate conveyor 5, like the elevating conveyors 3 and 4, has a conveyor belt 27 that contacts and drives the trays T at its side edges 26, and a conveyor belt 27 that guides the trays 1 to 1 in an upright state. The guide plate 28 (only a part of which is shown in the figure) is formed to circulate in a substantially rectangular loop shape. Then, in the middle of the real bobbin conveyance path 10 on the - side and a part of both sides sandwiching this,
Further, on the opposite side, an intermediate portion of the empty bobbin conveyance path it is formed.

As shown in FIG. 6, the drive system of the conveyor belts 20 and 27 consists of drive pulleys (motors) 29 provided on each conveyor belt.
and a guide 1- provided at the bending portion 24 and the direction change position.
30, each of which is independently driven in circulation. Especially the elevating conveyor 3
．． The one located at the bending part 25 of No. 4 is formed to change direction and give a 90 degree twist to the conveyor belt 20.

Further, at both ends of the elevator conveyor 3.4, twisting is similarly prevented by a diversion goury 31 in order to ensure a smooth transition from the outward route to the return route.

Next, the operation of this embodiment will be explained.

The tray T of the real bobbin B produced by the spinning machine 2 is
From the unloading conveyor 6, the bobbin is sent to the ascending path 7 of the elevating conveyor 3, which is the actual bobbin transport path 10. The conveyor bell 1-20 of the elevating conveyor 3 is driven in circulation by a drive pulley 29 and is biased by a spring 22 to contact drive the tray T and move it in the conveying direction A.

Then, the tray T to be transported is twisted at the bending part 25 before entering the vertical part 18 from the horizontal connection part 17, and is sequentially changed from an upright position and tilted in the transport transverse direction C.

Due to this attitude change, the continuously aligned trays T are smoothly turned upward and transported to the top of the vertical section 18, and then changed in attitude at the upper bending part 25, and then moved to the upper horizontal connecting part. At step 17, the user is placed in a standing position again.

Further, this tray T is moved from the end of the horizontal connection part 17 to the intermediate conveyor 5, and is conveyed horizontally while moving in the width direction of the machine along the loop, and is then transported to the lowering path of the elevator conveyor 4 for automatic wind mite detection. Enter 9. Then, from the horizontal connecting part 17 of the descending path 9, the posture is changed to the inclined position n41 at the bending part 25, and then conveyed downward at the vertical part 18, and after being changed to the upright position at the bending part 25 at the lower end, the horizontal connecting part 17 It is delivered to the carry-in conveyor 8 of the automatic winder 1 via .

On the other hand, the tray T of the empty bobbin B after being wound up by the automatic winder 1 is also lifted up from the unloading conveyor 12 of the automatic winder 1 by the elevating conveyor 4 while changing its position halfway, and is sequentially raised from the unloading conveyor 12 of the automatic winder 1 to the intermediate position: I It is conveyed to the carrying-in conveyor 14 of the spinning machine 2 via the belt conveyor 5 and the lifting conveyor 3.

In this way, the elevating conveyor 3.4 is provided to change the posture of the trays T as appropriate and convey them, and the trays T are arranged in a row and detoured upwards. Even if it is formed, spinning bobbin B or tray T
They can be transported smoothly without any interference between them, and the passage of workers etc. can be secured in the minimum necessary space.

That is, space saving in the system for connecting the automatic winder 1 and the spinning fi 2 is achieved.

Also, the conveyance path 10.1 between the automatic winder 1 and the spinning machine 2
1 to the lifting conveyors 3 and 4 and the intermediate conveyor 5, respectively.
Since it is divided into three parts and operated by separate drive systems, each part has a simple route, making maintenance easier.

In particular, between the solid lines, the vertical conveyor 3.4 is formed in a straight line and the phase difference in the machine width direction is eliminated by the intermediate conveyor 5, so that the horizontal bending of the vertical conveyor 3.4 is eliminated. This prevents an increase in driving force and the number of parts and a decrease in durability, thereby preventing an increase in equipment costs and frequent maintenance.

By further dividing the machine, even when the distance between the automatic winder 1 and the spinning frame 2 is long, it can be easily handled.

In other words, when the conveyance path 10.11 is operated with a single drive system, there is a natural limit to its conveyance force (conveyance amount), and when the machine arrangement is such that the conveyance distance becomes long, the installation of the conveyance device was difficult. In the present invention, since the conveyance force of the conveyor is substantially increased, direct connection through the gate-like conveyance path can be realized even in lines where the automatic winder 1 and the spinning frame 2 are separated.

The present invention can be applied without changing the elevating conveyor, no matter what the positional relationship between the automatic winder 1 and the spinning frame 2 is, if the intermediate conveyor is formed to match this. For example, even when the automatic winder 1 and the spinning machine 2 are arranged in parallel or at right angles, if the elevating conveyor is connected to the loop of the intermediate conveyor, the predetermined can form a transport path.

Therefore, the lifting conveyor 3.4 may be formed as a unit, which is very practical in terms of manufacturing the device and keeping it in a spinning factory or the like.

Furthermore, not only the 1:1 delivery as shown in the figure, but also when there are two or more spinning machines 2 and one automatic winder 1, each lifting conveyor can be connected to the intermediate conveyor as appropriate. Applicable.

In this case, it is desirable to provide a distribution mechanism at the upper end of the elevating conveyor so that the spinning bobbins can be equally loaded and unloaded into each spinning spinning R2.

Furthermore, in addition to forming the conveyance path into a gate shape as in the above embodiment, it is also possible to form it so as to detour downward.

That is, as shown in FIG. 7, the hoistway of the elevating conveyor is reversed to that of the previous embodiment, and the spinning bobbins B coming out of the unloading conveyor 12 of the automatic winder 1 are as follows: Lifting =? After being conveyed downward while being tilted by a conveyor 42, and conveyed horizontally by an intermediate conveyor 43 along the bottom surface of a trench 44 formed under the floor,
It is lifted up by the lifting conveyor 45 on the spinning machine 2 side and delivered to the carry-in conveyor 14 thereof. And aisle 16 is
The mark is formed on the upper surface of the cover plate 47 provided to cover the trench 44.

According to this configuration, there is no limit to the space above the passage 46 compared to the case where the conveyance path is formed in a gate shape, and it is extremely versatile.

Although the intermediate conveyor is shown as being circulated by four pulleys in the drawings of the above embodiment, it may be circularly driven by two large-diameter pulleys.

Moreover, although the elevating conveyor tilts the tray inward, it may be tilted toward an outer lock.

Furthermore, although the intermediate conveyor is formed in a loop shape, even if two independent conveyors are used for the actual bobbin measurement and the empty bobbin side, there is no loop.

The present invention is not limited to the transportation between the automatic winder and the spinning machine shown in the above embodiments, but is widely applicable to systems that transfer spinning bobbins.

"Effects of the Invention" In summary, according to the present invention, the following excellent effects are achieved.

Elevating conveyors are provided to transport the trays vertically by tilting them in the transverse transport direction on their outward and return journeys, and an intermediate conveyor is provided between them to connect the mutual transport routes. This allows for space-saving passageways for workers, etc., and allows for appropriate arrangement of all types of machine bases, greatly improving versatility.
