Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a bobbin and / or a bobbin tube, wherein the bobbin and / or the bobbin tube are respectively fitted on spindles of a pallet, and the pallet is continuously mounted. Are driven by means of a transportable means which can be driven in a linear manner and are slidably guided along guide rails during ascending and descending transports, the guide rails having a spindle on the side opposite to the transporting means. The present invention relates to a type that is arranged corresponding to the upper surface of a pallet base plate.

[0002]

In a corresponding device known from EP 0 455 989, a circulating transport means, in particular a chain, is equipped with a driving spindle. The entraining spindle engages between the spokes of the base plate of the transport pallet, thereby transporting the pallet substantially depending on such an entraining spindle also in the vertical section by means of a form connection. This ensures a very reliable entrainment without having to clamp the pallet between the guide means. However, if the entraining spindle is introduced between the spokes in the pallet, for example during the deflection of the pallet to a vertical transport section, the pallets are partially severely damaged by the jamming and consequently the transport system of the transport means of the pallet. All stop.

A further device of the type mentioned at the outset is known from US Pat. No. 5,097,943. In this device, guide rails load the pallets in the direction of the conveying means, which is formed as a circular or substantially circular belt. The conveying means entrains the pallet using friction. The transport means is supported on the side of the transport means opposite the pallet. This device has the advantage that a pallet with a bobbin or a winding tube or possibly a pallet with no load can be guided almost arbitrarily in the guide space, for example to form a bridge. ing. The transport belt is guided along a predetermined route using a driving / deflecting roller. The pallets are guided such that the spindle is oriented perpendicular to the conveyor belt. In this case, during horizontal transport, the spindle is oriented vertically upward. Transport of the pallets in order to be able to deflect the conveyor belt from above in the horizontal direction by means of deflecting rollers or to be arriving from above and to be deflectable in the horizontal direction by means of deflecting rollers, and nevertheless In order to hold the belt in contact, the guide rails are deflected, at least in the area of the deflection rollers, such that the pallet is tilted by 90 °.
The tilting of the pallet is carried out in such a way that the spindle of the pallet is oriented parallel to the axis of the deflecting roller in the area of the deflecting roller, so that the base plate of the pallet can be held in contact with the transport belt. it can. A problem arises when such an apparatus is actually realized. On the one hand, in order to be able to reliably transport pallets with possibly heavy bobbins in the vertical direction,
On the other hand, there must be sufficient frictional action between the base plate of the pallet and the conveyor belt, while on the other hand the friction between the conveyor belt and the guides of this conveyor belt and the upper surface of the base plate of the pallet and the guide I want to minimize the friction between the rails. It is difficult to find a practically satisfactory compromise between conflicting demands on frictional action.

[0004]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve a device for transporting bobbins and / or winding tubes of the type mentioned at the outset, in which the pallets are clamped or acted upon by a very high frictional action. The goal is to not be damaged.

[0005]

SUMMARY OF THE INVENTION In order to solve this problem, according to the configuration of the present invention, the entraining element of the conveying means protrudes from the slideway for the lower surface of the base plate of the pallet. When the continuous transport is blocked, the pallet can pass through the lower surface of the base plate, and at least one of the entraining element and the pallet is shifted in the lateral direction with respect to the transport direction.

[0006] Advantageous configurations of the invention are set out in the dependent claims.

[0007]

It is an object of the present invention to minimize the friction between the pallet and the guide rail on the one hand and the pallet and the runway on the other hand. Since the conveying means mainly entrains the pallet based on the shape connection between the entraining element and the pallet, the frictional action of the conveying means or the frictional action of the entraining element can be kept relatively small. In this case, however, it is also ensured that the device or the pallet or other components are not damaged during the blocking.

If the vertical distance between the entraining element of the conveying means and the guide rail corresponds approximately to the thickness of the base plate of the pallet, the following advantages are obtained. In the unlikely event that the pallet collides with an obstacle and cannot be moved further in the transport direction, the entraining element lifts the pallet and moves under the pallet without entraining the pallet. In the area of the transport section, which is directed upwards or downwards, as far as the spacing between the guide rail and the runway allows,
Pallet tilts. As a result, the pallet is held by the entraining element at the edge of the base plate, so that the pallet is entrained during the upward movement and does not drop during the downward movement. Additionally or alternatively, the guide rail can be configured to be flexible, so that the guide rail can be retracted when lifting the pallet.

A similar advantage is obtained if the entraining element is elastically deformable. In connection with the elastic deformability, the distance between the guide rail and the runway can be reduced, so that the possible tilting of the pallet is reduced. In the event of an obstruction, the entrainment element can be elastically deformed and move under the base plate of the pallet concerned without fear of damage to the pallet and / or part of the device. The lateral displacement of the entrainment element can also be achieved or increased by the fact that the groove-shaped recesses in which the transport means and the entrainment element slide are configured to be elastic or flexible. Can be.

In another embodiment of the invention, the conveying means is a wire rope to which the entraining element is attached.
This entraining element can be made of plastic, for example, and can be cast into a wire rope.

In another embodiment, the conveying means is a belt, in particular a circular belt, provided with bulges as entraining elements.

In another configuration of the present invention, a driving roller provided with a concave portion is arranged in the conveying means in a corresponding manner.
The spacing of the recesses in the circumferential direction corresponds to the distance of the entrainment element of the transport means. In this way, a gear-shaped drive roller is provided which is sufficiently shape-connectable and enables the drive of the transport means. Advantageously, the deflecting rollers are configured accordingly.

Further features and advantages of the invention are described in the following description of an embodiment shown in the drawings.

[0014]

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

A transfer device is also provided between the automatic winder and a supply station for the bobbin or between a bobbin forming machine such as a ring spinning machine, and the pallet 10 is used by the transfer device. The pallet 10 is transported while holding a bobbin or an empty winding tube, or even in an empty state, that is, a state where nothing is placed. Such a pallet 10 is shown, for example, in FIGS. The pallet 10 has a generally circular base plate 11, from which a spindle 12 protrudes from the top surface of which a bobbin tube or an empty tube can be inserted. . The winding tube is supported on the annular collar 13 in the vertical direction. The base plate 11 may be a closed circular disc or a ring connected via spokes to a hub supporting a spindle 12. Edge 1 on the lower surface of base plate 11 of pallet 10
4 is advantageously chamfered.

In most areas, the pallet 10 is transported in the horizontal direction. In this case, as shown in FIG. 1, the base plate 11 is oriented horizontally and the spindle 12 projects vertically. However, it is necessary to provide a transport path between the automatic winder and the supply station for the bobbin or the bobbin forming machine. To provide such a transport path, US Pat. No. 5,097,943 or EP 045
A so-called Kopsbrücke is formed, as is known from U.S. Pat. Conventionally, such a cup bridge is a special transport device having special driving means. The cup bridge is
A horizontal supply section, an upwardly directed, preferably vertical section following this supply section, an upper horizontal section bridging the passageway, and a downwardly directed, preferably vertical, subsequent to this section And a horizontal delivery section following this section.

It is possible to operate only one transport means, which transports over the entire area of the cup bridge, over all sections. However, dividing the transport means, i.e. the first transport means for the supply section and the first upward guiding section, the second transport means for the horizontal section bridging the passage, It is also possible to provide a third transport means for the guidance section and the subsequent delivery section.

The pallet 10 is guided in the device according to the invention in a manner analogous to that described in US Pat. No. 5,097,943. The pallet arrives with the spindle upright, and is then rotated in the area of the lower diverting roller by 90 ° so that the pallet spindle extends parallel to the axis of the diverting roller. Thereafter, in this state, the pallet is transported upward and guided through the upper deflecting roller. The pallet is then guided in this state, too, via the section bridging the passage, to the downward guide section. The pallet is then pivoted again by 90 ° in the area of the lower deflecting roller and returned to its original position, which then passes through the transfer section again with the spindle oriented vertically. However, the pallet may be pivoted again in the first vertical guide section upward and returned to its original state, so that the pallet turns the spindle radially with respect to the next deflecting roller. In this state, the sheet is guided through the deflection roller. In this state, the pallet may subsequently be guided to the lower deflecting roller, after which the pallet is again first turned by 90 ° in the area of this deflecting roller and then leveled again. However, as shown in FIG. 3 of U.S. Pat. No. 5,097,943, the pallet remains tilted until it reaches the upper diverting roller, and is only leveled again after passing the deflecting roller. It is also possible. The lower surface of the base plate 11 of the pallet 10 is guided along the slideway 15.
Guide rails 16 and 17 are arranged correspondingly on the upper surface,
The guide rails 16 and 17 are made of, for example, a round rod made of metal or round steel. The runway 15 is advantageously formed from a thin plate. The runway 15 and the guide rails 16, 17 fixed to the runway 15 via U-shaped members 18, 19, as known from US Pat. No. 5,097,943 for guide rails, The pallet 10 is deflected or twisted corresponding to a desired tilting movement (rotational movement). The U-shaped members 18, 19 can also be limited and resiliently formed, if necessary, with some flexing.

The transfer of the pallet 10 is performed by using a transfer means 20. The transfer means 20 mainly includes the pallet 1
0 is moved by Formschluss. In the embodiment, the transport means 20 is the rope 2
1, in particular a wire rope, on which a spherical entraining element 22 is mounted at regular intervals. The entraining element 22 is guided and supported in a groove-shaped recess 23 of the slideway 15. Since the entraining element 22 protrudes somewhat from the runway 15, the entraining element 22 hits the chamfered lower edge 14 of the base plate 11 of the pallet 10. As a result, the pallet 10 is entrained and moved in the transport direction along the slideway 15. Usually, the transport means does not protrude from the slideway 15. This is because the transfer of the pallets by the shape connection is performed via the entrainment element. However, it is not always necessary to sink the transport means into the slideway 15.

Even if the pallet 10 collides with an obstacle, or the pallet 10 is blocked from continuing movement for some reason, the transporting means 20 can continue to travel without danger of breakage. It has become. Different means can be provided individually or in combination with one another in order to enable the continued running of the entraining element 22 without the entrainment of the pallet 10. If a sufficiently rigid, non-deformable or non-deflectable entrainment element 22 is provided, the pallet is moved so that the entrainment element 22 can travel under the base plate.
It must be movable away from the runway 15. In this case, the guide rails 16 and 17 and the entraining element 22
Of the base plate 11 of the pallet 10 must at least correspond to the thickness or height of the base plate 11 of the pallet 10. However, if the entraining element 22 is elastically deformable, in particular if it is made of a rubber-elastic material, the distance is reduced and the distance between the guide rails 16, 17 and the sliding guide is reduced. , Approximately corresponding to the thickness or height of the base plate 11 of the pallet 10. Guide rail 1
The small spacing between the slideways 6, 17 and the slideway 15 is, as already mentioned above, held so that the guide rails 16, 17 resiliently flex away from the slideway 15 when a predetermined force is generated. It is also possible in cases. Another means for setting a small distance and still allowing the passage of the entraining element 22 is, for example, as shown in FIGS. 4a and 4b, a groove-like recess 23 of the runway 15 In the form of a spring-resilient construction or holding. In this case, FIG. 4a shows a "normal" state, which is the case without blocking. FIG. 4 b shows a state in which the groove-shaped recess 23 has fully or completely accommodated the entraining element 22.

In this case, however, the guide rails 16, 17 are additionally provided in a spring-like manner in order to permit the passage of the entraining element 22, at least in the region of the deflecting rollers, in which the pallet 10 is tilted (turned). It must be able to flex.

FIGS. 5a and 5b show FIGS.
Similarly to b, a “normal” state and a blocking state are shown. However, in this embodiment, each of the entraining elements 22 itself is elastically bent, as described above, instead of the groove-shaped concave portion 23.

The spacing between successive entraining elements 22 is
It is adjusted to the shape and / or size of the base plate 11 of the pallet 10. That is, it is desirable to prevent the base plate 11 of the pallet 10 from being placed on the two entraining elements 22 or the plurality of entraining elements 22. If the base plate 11 consists of a closed disc, it is desirable to make the spacing of the entraining elements 22 somewhat larger than the diameter of the closed disc. However, if the base plate 11 consists of a ring which is held on the hub by spokes, the entraining elements 22 can be arranged at a distance corresponding to the thickness of the ring. Base plate 1
If the underside of one is provided with a circumferential annular collar, the entraining elements 22 may be arranged at intervals corresponding to the thickness of the annular collar.

The conveying means 20 may be constituted by a belt. The belt is reinforced with a fabric, and has a bulge formed into a spherical shape or a barrel shape.

A vertical section or simply an inclined section,
Since the pallet 10 is inclined in a direction away from the slideway 15 with one entrainment element 22 as a starting point, as shown in FIG. 2, the edges of the upper surface are formed on the guide rails 16 and 17 at positions substantially diagonally located. It is guided along. Even in such a state, the entrainment element 22 carries the pallet 10 sufficiently based on the shape connection. If the distance between the entraining element 22 and the guide rails 16, 17 is relatively large, there is a risk that the pallet 10 will slide undesirably and will not be entrained upward or fall downward. The danger is that the guide rails 16,1
The smaller the distance between the runway 7 and the runway 15 is, the smaller it is, and nevertheless, the entrainment element 2
The greater the force required to pass 2 underneath the lower surface of base plate 11 of pallet 10, the lower the force.

FIG. 3 shows a driving roller or a deflection roller 2.
Four embodiments are shown. A concave portion 26 is provided on the running surface 25 of the deflecting roller 24, and the interval between the concave portions 26 in the circumferential direction is determined by the entrainment element 2 of the conveying means 20.
Corresponds to an interval of 2. Further, the runway 15 and the guide rails 16 and 17 are defined by U.S. Pat. No. 5,097,943.
As described in the specification, the pallet 10 is appropriately bent to guide the pallet 10 along a curved track.
The pallet 10 rests on the end face of the deflection roller 24 in the area of the deflection roller 24. On the side of the conveying means 20 opposite to the pallet 10, since the outer portion of the slideway 15 is arranged at the height of the deflection roller 24, the pallet 10
In contrast, a consistent support is formed along the straight transport section. The inner part of the runway 15 is a deflection roller 24
Has been suspended in the area. When the transporting means 20 is sufficiently tensed, the support portions along the groove-shaped recessed portions 23 are limited to a minimum. This is because the transport of the pallet 10 is mainly performed by the shape connection, not the friction connection. Thereby, the friction of the conveying means 20 or the friction of the entraining element 22 in the groove-shaped concave portion 23 is also minimized.
