Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bobbin conveying device. For example, the pipe yarn produced by a spinning machine is transported to the winder area, or the empty bobbins that have been rewound by the winder are transported to the spinning machine area by randomly storing them in boxes. Various conveying means are used, such as a type in which the bobbins are placed on a conveyor and conveyed one by one, and a type in which the bobbins are placed upright on an independent conveyance medium and conveyed.

Among the above methods, in the type in which the bobbin is placed directly on the belt conveyor for conveyance, in order to make effective use of the space, it is necessary to place the bobbin at least a certain distance above the machine, that is, from the floor, at least the height of the worker. A conveyor is disposed horizontally or inclined at the above height position and conveys the bobbin to a desired bobbin processing area.

In this case, it is necessary to raise the bobbin to the conveyor at a high place, and for this purpose, a conveyor that rotates vertically is installed, or a chuck device that grips each bobbin is moved along a vertical guide rail. It is also used to raise the temperature.
Therefore, a conveying device that rotates in the upper horizontal direction and a device for vertically conveying the bobbin are required, and a driving source for each conveying device must also be provided, resulting in multiple structures or Even in the transfer section from conveyance to horizontal conveyance, care had to be taken to ensure smooth conveyance.

The present invention focuses on the above points and provides a device that enables lifting and horizontal conveyance of articles such as bobbins with an extremely simple structure. Applicable to transportation.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows the layout of a spinning winder in which a spinning machine and a winder are directly connected.A spinning machine 1 and a winder 2 are installed side by side, and a real bobbin 3 on which yarn produced by the spinning machine is wound is, for example. A real bobbin conveying means is inserted and supported by a peg on a transport band 4 that moves along the front side of the spinning machine in the longitudinal direction, is transported in the direction of arrow 5, is fed into a real bobbin supply device 6, and waits below. For example, the disk is inserted upright into a peg tray having a protrusion for inserting a bobbin in the center, which is transported on a belt conveyor, and is supplied to each winding unit 7 of the winder. Reference numeral 8 denotes a preparation device having a yarn end pulling device for releasing the bunch winding of a real bobbin coming out of the spinning machine, a device for detecting the presence or absence of yarn on the bobbin, and the like.

Empty bobbins or bobbins with residual yarn that have been completely wound in each winding unit of the winder are transported on an empty bobbin transport conveyor that is laid along the winding unit while being inserted into a peg tray.

When the bobbin processing device reaches the 9th position, an empty bobbin is found.
The bobbins with remaining yarn are sorted, and the empty bobbins are extracted from the peg tray and transferred to the empty bobbin conveying device 10, which will be described later.
It is then transferred horizontally above the spinning machine.
The empty bobbins transported to the end of the spinning frame 1 are stored in the lower transport band 4 or the empty bobbin storage box via the chute 11 at appropriate timing.

In this way, the spinning machine 1 and the winder 2 are directly connected through the full bobbin conveyance path and the empty bobbin conveyance path.

The empty bobbin conveying device described above will be explained with reference to FIGS. 1 to 3.

The empty bobbin conveying device 10 has a vertical conveying path 12, a curved conveying path 13, and a horizontal conveying path 14.

For the conveyor support material 15 extending over the entire conveyance path, a molded member having a cross-sectional shape shown in FIG. 3 is used, for example. That is, the supporting member 15 has belt guide portions 18 and 19 and a recess 21 for fixing the mounting member 20 when attaching the supporting member to the column on the side surface, and the cover 22 is integrally formed with the supporting member 15. The belt guide portions 18 and 19 have cutout portions 23 and 24 for passing the belt through. The cover 22 has a circular cross section or a deformed surface, and the passage space 25 formed by the cover 22 has a cross-sectional area at least larger than the maximum diameter D of the empty bobbin 26 in the case of empty bobbin transfer. It has a large width W and height H, and is large enough to prevent two empty bobbins from being transferred in parallel, and one empty bobbin from being pinched between the other empty bobbin and the inner surface of the cover. It is.

Further, the mounting member 20 of the support member 15 is carried into the block 27 inserted into the recess 21 on the side surface, and the mounting member 20 is fixed to the support column 29 by the fixing fitting 28.

It constitutes a horizontal conveyance path 14, and is appropriately fixed to a support.

FIG. 4 shows how the horizontal conveyance path 14 is installed above the spinning frame 1, and is installed at an appropriate position on the support 29 that stands upright in the center of the spinning frame 1, that is, above the feeder 31. There is.

Further, in FIG. 2, in the bobbin input section 32 of the above-mentioned conveyance device, the support member 15 is fixed vertically, a part of the cover 22 is cut off, a bobbin chute 33 is attached to the cut section, and the bobbin processing device 9 As a result, the empty bobbin 26a in the raised position is thrown into the chute 33, whereby the empty bobbin is placed via the chute 33 on a pin protruding from the conveyor surface in the vertical position.

In the case of FIG. 2, a chute 35 for dropping the bobbin into the bobbin storage box 34 below is continuous at the end of the horizontal conveyance path 14.

36 is a rubber plate that cushions the impact of the bobbin.

5 to 7 show a driving device for the conveyor belt 16 passing through the conveyance path.

Brackets 3 fixed to both sides of support member 15
The motor 3 is attached to the bracket 37 on one side of 7, 38.
9 is fixed, and a drive pulley 41 is fixed to a shaft 40 of the motor 39. At the center of the outer peripheral surface of the pulley 41, there is an annular groove 44 through which the screw head 43a of the screw 43 for fixing the pin 42 to the belt 16 passes.
is formed. At the other end of the endless belt 16, which is placed around the pulley 41,
It is placed on a driven pulley 45.

Furthermore, the tension pulley 4 of the belt 16
6 and 47 are the shafts 4 supported on the brackets 37 and 38.
8 and 49 so as to be freely rotatable, and press against the belt 16 near both sides thereof to apply appropriate tension to the belt. Tension pulley 46, 47
The distance l1 between them is set to a size that allows the pin 42 on the belt to pass through without any hindrance. A pulley 50 similar to the tension pulley is provided at the other belt end, as shown in FIG.

Moreover, since the belt 16 passing through the conveyance paths 12, 13, and 14 rotates along the curved support material shown in FIGS. 1 and 2, the belt guide surface (third 18, 19), the drive pulley 41
Since there is a risk of dry slipping if only the nip roller 5 presses the belt of the drive pulley 41.
1,52 are provided.

That is, the nip rollers 51, 52 are supported by pivots 57, 58 at intermediate portions of levers 55, 56 which are pivoted by shafts 53, 54 fixed to brackets 37, 38.
Tension springs 61, 62 are connected between the ends of the levers 55, 56 and fixing pins 59, 60 on the brackets 37, 38.
Therefore, the nip rollers 51, 52 are pressed against the belt 16 on the drive pulley 41 by the spring force.

Note that the nip rollers 51 and 52 are in pressure contact with the belt at a certain distance from both side edges of the belt 16, similar to the tension rollers 46 and 47, and there are also holes between the nip rollers 51 and 52 for passing pins on the belt.
A gap l1 is provided.

Note that the nip rollers 51 and 52 may be one roller. That is, in the case of a large-diameter roller, for example, a roller whose radius is larger than the length of the pin 42, the nip rollers 51, 52 are formed by forming an annular groove deep enough to allow the pin to pass through the center of the outer periphery of the roller. It can exert the same effect.

Therefore, belt slippage at the driving pulley 41 portion, which may occur due to resistance at the curved portion of the belt 16, can be avoided by the nip rollers 51 and 52.
This can be prevented by pressing 6 onto the surface of the drive pulley 41.

FIG. 8 shows the relationship between the empty bobbin 26 in the curved portion 13 of the conveyance path 10 and the radius of curvature of the curved portion,
If the radius r is smaller than the length L of the bobbin as in the curved portion 13a, the bobbin may tilt at the curved portion and separate from the pin 42, causing the cover 2
2a is provided, the cover 22a and the belt 16
There is a risk that the bobbin may get caught between the a sides.

Moreover, the degree of curvature of the belt becomes steeper, and the bending stress of the belt increases, so that the life of the belt may be shortened. Therefore, the radius of curvature R of the curved portion 13 is set to an appropriate value based on the space, the length of the bobbin, the life of the belt, and the height of the horizontal phase portion.

For example, if the height of the horizontal conveyance path 14 is 2 m and the length of the bobbin to be conveyed is 21 cm, the appropriate radius of curvature R is about 1 m. 9 and 10 show an example of the bobbin loading portion of the vertical conveyance path 12, in which the cover portion 22 of the support material 15 is removed,
A guide chute 33 is fixed to a support member. The guide chute 33 has an upper surface 70 and a front portion 7.
1 is open for entering the bobbin, and the side plates 72, 73
A bobbin passage 75 is formed by the bottom plate 74 and the conveyor belt 16.

Further, a flapper 77 is swingably supported on a shaft 76 fixed between the side plates 72 and 73, and the flapper 77 is normally positioned at a slight inclination to the solid line position in FIG. 9 due to its own weight. The lower plate 78 of the chute 33 serves as a bobbin mounting surface having a gap 79 through which the pin 42 of the belt can pass.

Therefore, as shown in FIG. 9, the empty bobbin 26 inserted into the tray 80 on the empty bobbin transport path is moved up and down from the tray 80 in the bobbin processing apparatus 10 previously filed by the present applicant. 81
When the grip is released, it falls inside the chute 33 and is placed on the lower plate 78 while pushing the flapper 77 to the position 77a indicated by the two-dot chain line. be done. In this state, as the conveyor belt 16 rotates, the pin 4 on the belt
2 is locked to the bottom of the bobbin 26b, and the bobbin 26b
rises along the vertical conveyance path, and the curved conveyance path 13,
It is conveyed along the horizontal conveyance path 14. Note that when rising from the bobbin mounting surface 79 in the chute 33,
Even if the bobbin tends to tilt to the left in FIG. 9, it rises while being guided by the side surface 77b of the flapper 77, so that the bobbin is vertically conveyed without falling over.

Note that 45 is a driven pulley of the conveyor belt 16, and depending on the situation, it is also possible to bias the tension roller 46 against the belt 16 as shown in FIG.

In the above-described bobbin conveying device, when the bobbin is dropped into the chute 33 at the input section 32 as shown in FIGS.
The bottom of the bobbin is engaged with the bobbin, and the bobbin is transferred continuously through the vertical conveyance path 12, the curved conveyance path 13, and the horizontal conveyance path 14, that is, during this time, the bobbin is not transferred to another conveyor or conveyance means. It is transported and supplied from the horizontal end to a peg on the transport band on the spinning machine side, or stored in a bobbin storage box.

In the above example, the empty bobbin was transported to the spinning machine side, but it is also possible to collect it at the winder side.Also, the spinning machine shown in Fig. 1 has spinning spindles arranged back to back. If so, it is also possible to provide a movable guide for distributing bobbins at the end of the horizontal transfer section so that the bobbins can be fed into the chute corresponding to each spindle example.

As described above, in the present invention, when only the empty bobbins among the various bobbins discharged from the winder are transported to the spinning machine, the empty bobbins can be placed one by one on the conveyor and transported, and the inside of the cover can be transported. This prevents air lint, dust, etc. from adhering to the empty bobbin, and allows it to be transported smoothly along the inner surface of the cover, allowing efficient bobbin transport between the winder and spinning machine without any stagnation. A curved conveyance path is provided between the paths, and the above-mentioned vertical conveyance path, curved conveyance path,
Since a conveyor belt is installed that passes continuously between the horizontal conveyance paths, only one drive source is required, which is more economical than when the vertical and horizontal conveyance paths are separated. Since there is no transfer during the route, smooth conveyance is possible, and in the case of transferring a tube yarn with a yarn layer, damage to the surface of the yarn layer during transfer can be prevented. can.
