Description

The invention relates to a transport system according to the preamble of the first claim.

From a large number of publications it is known to transport coils or bobbin tubes on independent individual carriers in closed transport systems. JP-OS 52-25 139 describes a transport system in which cops and sleeves are transported with their individual carriers in different transport levels. The respective horizontal transport takes place by means of frictional engagement through conveyor belts, the individual carriers being guided through guide slots along these transport routes. The transport levels are changed by means of elevators, which are formed by lifting and lowering transport track sections. Several individual carriers are combined in groups on these transport sections. These elevators work discontinuously and are not suitable for a high throughput of single girders.

A similar, discontinuously operating transport system for lifting and lowering individual carriers with coils or coil sleeves placed vertically on them is described in DE-PS 36 09 071 described. However, according to this variant, the individual carriers are not grouped together. Due to the discontinuous operation, the transport capacity is also severely limited with this solution.

The generic DE-OS 36 30 670 also describes a transport system for coils and bobbin sleeves placed on independent individual carriers, in which parts of the transport path leading obliquely upwards are provided to bridge the height differences. This transport system can be used advantageously for the formation of an operating aisle between connected machines. In order to ensure that the individual carriers are also carried along by the conveyor belt in the transport sections which run obliquely upwards or downwards, they must at the same time rest against the plates forming the guide slot on the top of their base plate. It must be ensured that the frictional force between the conveyor belt and the individual carrier is significantly greater than the frictional force between the individual carrier and the guide plates. For this purpose, the conveyor belt must be pressed resiliently against the individual carrier so that it is also taken along. Apart from the fact that the contact pressure of the conveyor belt must be kept constant over the entire transport route, the surface of the base plates of the individual carriers is exposed to the frictional forces with the guide plates over the entire transport section. A relatively rapid wear of the individual carriers cannot be avoided. The transport routes are only aligned approximately vertically, which results in an increased space requirement, which limits the width of the aisle. Due to the system, only a gradual change in the direction of transport is possible, which is also at the expense of the width of the aisle.

DE-OS 37 43 882 describes a similar system, but the guide plates are replaced by flexible, round guides, which also have this guide slot for the base of the Form single carrier. The solution described in this publication allows the individual carriers to tilt during their transport. The conveyor belts, which also transport the individual carriers by friction, must be very narrow, since they are folded by 90 degrees at deflection points. In this system too, such a pressing force of the transport belt against the individual carrier must be secured over the entire course of the route, with which a friction can be achieved which significantly exceeds the sliding friction between the top of the individual carrier base and the guides forming the guide slot. The system is therefore also subject to relatively high wear.

Based on this prior art, the object of the invention is to propose a simply constructed transport system which ensures high transport capacity, a small space requirement and constant functional reliability for single carriers with attached coils or bobbin sleeves between transport levels of different heights.

This object is achieved by the features of claim 1.

The drivers attached to the rotating means of transport ensure that the individual carriers are securely grasped at the transfer point and are transported without any frictional forces. This minimizes wear on the individual carriers and the entire transport system. In this way, the functionality of the entire system is extended considerably. The avoidance of the frictional forces also prevents the different wear of the individual carriers and the transport route sections. As a result, a problem of known systems does not arise, which consists in the fact that the different wear results in different frictional forces and thus a different entrainment of the individual carriers leads along the transport route. In known devices, this problem quickly increases to such an extent that it no longer functions.

In cooperation with the guiding surfaces arranged at the transfer point of the individual carriers, the drivers ensure that the individual carriers can be tilted into the new transport position without any significant space requirements. Due to the continuous operation of the system, a very high transport capacity is achieved. The simple structure ensures high functional reliability.

The invention is advantageously developed by the features of claims 2 to 20.

In all variants of the invention, a separation device of the pallets can be dispensed with at the delivery point of the individual carriers. In addition to simplifying the construction, this also increases the possible transport capacity. The invention also makes it possible to tilt horizontally delivered individual carriers at the delivery point by 90 degrees without the need for a bulky transport path curvature, as is known from the prior art.

With the help of lifting profiles, the individual carriers can be transferred from the carriers to another conveyor belt just as easily and continuously. Different variants for fixing the position of the individual carriers on the carriers do not cause any significant additional friction. Their structure is very simple.

The transport system according to the invention also provides as a variant that the individual carriers remain on the carriers all the way through a cop bridge. It is also possible to do both To use trumes of the circulating means of transport for the transport of individual carriers, whereby a doubling of capacity is achieved without taking up additional space.

Since in particular machines for the production and further processing of cops have a considerable length and are set up head to head, it is usually desirable to provide an operating aisle between these machines. These are usually the Transport routes designed like a bridge, with an upper horizontal part is arranged at least at a height that allows free passage for people. In the case of a bridge of this type, it is particularly problematic to lift the individual carriers with attached cops or sleeves from the level of the transport routes provided near the ground in the respective machine area to the level of the upper horizontal bridge part or to lower them again.

As can be seen from FIG. 1, cops 2 placed on individual carriers 1 are fed along a transport path 3 to a vertical transport path. The individual carriers 1 have spokes 1 ', which connect a base 1' 'provided with the plug-on mandrel for the cop 2 to a casing ring 1' ''.

The conveyor track 3 has a conveyor belt 4, which feeds the individual carriers 1 with cops 2 to the transfer point on the vertical transport route. The conveyor belt 4 is deflected by a deflection roller 4 '. The drive of this conveyor belt 4 is not shown here. The individual carriers are guided on their jacket rings 1 '' 'by guide rails 5 which have an angled part 5' at the transfer point of the individual carriers. As a result, the individual carriers 1 are displaced transversely to the transport direction of the conveyor belt 4.

The foremost individual carrier 1 abuts a guide plate 10 or a stopper 10 'of this guide plate 10. In this position, it is gripped by a drive pin 13 attached to a chain 12, which first lifts the front part of the single carrier and then into one of the openings between the spokes 1 'penetrates with further tilting of the individual carrier. The single carrier tilts into a vertical position. In this vertical position, the individual carrier is then exclusively carried by the driver 13 held on which the outer ring 1 '''of the single carrier rests with its inside.

As can be clearly seen from FIG. 2, an upper guide plate 6 is arranged such that it completely pushes the individual carrier 1 onto the driving pin 13 after it has tilted. The guide plate 6 then merges into a guide plate 11, by means of which the individual carriers are prevented from tipping during transport from the vertical position together with an opposite guide plate which is also provided with the reference number 11. The guide plates 11 cooperate with guide plates 10, on which the individual carriers slide with their underside and between which the driver pins 13 pass.

For a better takeover of the individual carriers 1, the driver pins 13 contain notches 13 ', which are arranged so that they are at the front in the transport direction of the drivers 13. The notches 13 'are arranged at such a distance from the chain 12 that they grip the single carrier 1 ready for transfer on the inside of its casing ring 1' '' and form a fulcrum during the tilting movement of the single carrier. Depending on the arrangement of further guide plates, the individual carrier 1 is then pushed further onto the driving pin 13. This notch 13 'ensures that the individual carrier cannot slide off the carrier pin 13 when it is received.

On the side opposite the guide plate 6, a guide plate 7 is attached, which has hinges 8, about which it can be pivoted. This guide plate 7 is pulled by a tension spring 9 against one of the guide plates 11. This resilient attachment of the guide plate 7 prevents individual carriers from jamming during the takeover.

As can further be seen from FIG. 1, the circumferential chain carrying the driving pins 13 has a transport direction which laterally leads obliquely upwards from the stop position of the foremost single carrier to be taken over and then transitions into a vertical distance in order to achieve a transport direction component transverse to the tilting plane of the cop 2 on. For this purpose, the chain 12 has, in addition to chain wheels 14 to 17, a chain wheel 18 which conveys to the chain 12 the change in transport direction provided in this area. Due to this special design of the single carrier take-over, the tilting or tilted cop 2 is guided laterally away from the feed direction of the subsequent cop. As a result, a collision with the subsequent cop can be avoided very effectively without having to provide a special stopping and separating device.

In the present variant, the chain 12 is driven continuously by a motor 19 acting on the sprocket 17.

For the sake of clarity in FIG. 1, the guide plates 10 and 11 have broken off upper horizontal parts 10 'and 11' which are asymmetrical. This results from the fact that the individual carriers 1 are transported suspended from the driving pins 13, and in the horizontal part of the transport route the direction of transport is no longer counter to gravity.

Lifting profiles 20 are arranged at the transfer point of the individual carriers from the driver pins 13 to an upper horizontal transport path 24, by means of which the individual carriers are tilted back into their horizontal position and lifted off the driver pins 13. For a safe transfer, it is necessary that the lifting profiles 20, which allow the free passage of the driving pins 13, guide the individual carriers until they have almost reached their horizontal position again.

A guide profile 21 supports this, on which the cops 2 rest with their winding-free head tip 2 'during the tilting. This ensures an almost jerk-free change in the position of the cops 2 and changing their direction of transport.

The conveyor track 24 has a conveyor belt 23 which is deflected by a deflection roller 23 '. The drive of this conveyor belt 23 is not shown here. At least one guide rail 24 is also arranged along the transport path 22, which guides the individual carriers 1 to their casing ring 1 ″ ″. This guide rail 24 is particularly important in the area of the transfer of the individual carriers 1 onto the conveyor belt 23.

Fig. 3 shows a variant of the formation of a driver 26 on which a permanent magnet 27 is attached. In this case, the individual carriers 25 consist at least partially of ferromagnetic material. In this way it is possible to stabilize the position of the individual carriers 25 on the carriers 26. In this variant, the individual carriers 25 have a recess 25 'into which the drivers 26 engage. These individual carriers 25 also have a jacket ring 25 ″, which is, however, connected by a closed cover plate to the base 25 ″ ″ carrying the plug-on mandrel for the cop 2. When designing the magnet 27, it should be noted that its surface facing the individual carrier has at least such an extent that there is contact with the casing ring 25 ″ in all of the transport directions provided.

To ensure smooth takeover and transfer of the individual carriers 1, it is advantageous if their outer lower edge is slightly beveled.

4 and 5, a variant of the invention is shown, in which the transfer and delivery of the individual carriers is designed differently. One arranged in a lower level The conveyor track 28 has a conveyor belt 29 which is so entangled in its head area that the support surface formed by the upper run of the conveyor belt 29 is inclined by approximately 45 degrees for the individual carriers 25. This inclination is achieved by the deflection roller 29 'of the conveyor belt 29. In order to be able to restrict the entanglement of the conveyor belt 29 to an end section of this conveyor belt, conveyor rollers 30 are arranged not far from the deflection roller 29 ', which fix the lower run of the conveyor belt 29 and together with a guide profile 31 which is arranged so far above the conveyor track 28 That the free passage of the individual carrier 25 is possible, also fix the upper run so that the tilting of the tape in the head area does not propagate beyond this point. Guide profiles 32 and 33 ensure exact positioning of the individual carriers 25 with cops 2. The guide profile 32 is arranged at a height at which it can guide the cops 2 on the winding-free head tip 2 '. This guide profile is shaped and arranged in such a way that it guides the cops 2 such that they largely retain their position perpendicular to this transport surface with the increasing inclination of the transport surface formed by the conveyor belt 29. The guide profile 33 ensures that the individual carriers cannot leave the conveyor belt 29 in the direction of its inclination. In addition, the guide profile 33 is angled at its rear end 33 'located in the transport direction in such a way that it stops the individual carriers 25 in a position in which they are transferred to drive pins 35 of a chain 34.

The chain 34 carrying the driving pins 35 at intervals is deflected by chain wheels 38 and 39. The sprocket 38 is continuously driven by a motor 40.

As can be seen in particular from FIG. 5, the single carrier stopped in the delivery position by the driving pins 35 at the rear end 33 'of the guide profile 33 projects above the conveyor belt 29 in the direction of the chain 34. In this way, on the one hand, the free passage of the driving pins 35 on the conveyor belt 29 or the deflection roller 29 'is ensured. On the other hand, this foremost single carrier 25 can be securely gripped and taken along by the driver pin. The guide profile 32 ensures that the tip of the head 2 'is supported until the tilting process of the individual carrier 25 is completed. Guide plates 36 and 37 arranged in pairs along the vertical transport path ensure that the individual carriers 25 remain securely on the driver pins 35 while maintaining the orientation of cops and individual carriers. In the area of the upper sprocket 39, sections 36 'and 37' of the guide surface are also asymmetrical, as was already described in the first variant.

At the transfer point of the individual carriers with cops on a transport path 41 arranged in an upper level, lifting profiles 47 are assigned, with the aid of which the individual carriers are tilted until they assume a position in space which corresponds to the inclination of the conveyor belt 42 in its head region. Analogous to the lower transfer point, the conveyor belt 42 is likewise folded at approximately 45 degrees by the inclined arrangement of a deflection roller 42 'at the upper discharge point. Tape rolls 43 and a guide profile 44 also prevent this tape entanglement from continuing to run. Guide profiles 45 and 46 are also provided at this point for the safe guiding of the individual carriers 25 and the cops 2 at their head tips 2 '. The guide profile 45 stabilizes the tip of the head 2 'during the tilting when the cop 2 is released, as was already described during the transfer.

Only after the individual carrier 25 has been gripped by a driver pin 35 during the transfer and has been pivoted in the vertical direction by at least a certain amount does the subsequent individual carrier 25 lose contact with this front carrier Single carrier. Only then can the subsequent individual carrier 25 be transported further in the direction of the transfer position. The period of time until this subsequent individual carrier arrives directly at the transfer position is long enough to move the preceding individual carrier so far in the vertical direction that the inclined subsequent individual carrier 25 cannot collide with the preceding cop 2. It is advantageous that the vertical extent of the cops 2 arriving in the transfer position is correspondingly reduced by their inclination. As a result, a stop and separation device can also be dispensed with in this variant.

In the variant of the invention shown in FIGS. 6 and 7, a chain 48 carrying the carriers 49 runs over the entire area of a cop bridge. In addition, in the area of the lower level, transfer and delivery points are arranged opposite each other, so that both trumes and thus transport directions of the chain 48 are used for the transport of individual carriers 65 with cops 2 or sleeves 66. Compared to the first variants, it is also demonstrated here that the direction of feeding or discharging the individual carriers is not rigidly predetermined. The arrangement of the transport system according to the invention is thus extremely flexible.

The individual carriers 65 are transported along a transport path 58 on a transport belt 59 to the transfer point. The conveyor belt 59 is deflected by a deflection roller 59 '. The drive of the conveyor belt is not shown here. A guide plate 60 is designed such that it stops the foremost individual carrier 65 with its edge arranged slightly above the upper run of the conveyor belt 59 and holds it ready for engagement by drivers 49 of the chain 48. The guide plate 60 and the opposite guide plate 61 then form upper guide surfaces for the individual carriers 65 during of the tipping process. The respective individual carrier 65 slides from the stop position through a groove 60 'of the guide plate 60 behind this guide plate. The two guide plates 60 and 61 are shaped so that the gap width tapers towards the chain 48 upwards. As a result, the individual carrier 65 gripped by the carrier 49 is completely pushed onto this carrier 49. Support plates 50 for the individual supports 65 are connected to the drivers 49. The drivers 49 themselves carry a stamp-like thickening 49 'at their end facing away from the chain 48. This stamp-like thickening 49 ′ prevents the respective individual carrier 65 from sliding off the driver 49 or ensures that the individual carrier 65 is well supported on the support plate 50 during the entire transport.

In this variant, it is necessary that either the support plate 50 is rotatably mounted on the driver 49 or the driver 49 on the chain 48. This necessity arises from the fact that, in the case of changing transport directions, it must be ensured that the respective individual carrier 65 lies fully on the support plate 50.

The chain is additionally deflected by chain wheels 51 to 56 and in the transfer areas of chain wheels 51 ', 57 and 71 and in a delivery area by chain wheels 54' and 71 '. The sprocket 54 is continuously driven by a motor 75.

In the present example, an operating aisle 76 is to be bridged between a spinning machine, to which the transport routes 58 and 63 belong, and a winding machine, to which the transport routes 67 and 73 belong. Copes 2 delivered by the spinning machine are transported over the cop bridge to the winding machine side and transferred to the transport path 73. Copes, sleeves 66, which are unwound from the winding machine, become the drivers 49 of the chain 48 on the winding machine side fed. These sleeves 66 are transferred with their individual carriers 65 through the lower run of the chain 48 to the spinning machine side and thus to the transport path 63.

According to the previous examples, lifting profiles 62 and 62a are arranged on the delivery side of the sleeves 66 to the spinning machine, which lift the individual carriers 65 with the sleeves 66 attached by 90 degrees and transfer them to the upper run of the conveyor belt 64. The lifting profile 62a has an oblique side edge through which the individual carriers 65 are additionally displaced laterally during their tilting movement. It is also advantageous if the base formed by the lifting profiles 62 and 62a for the base plates of the individual carriers are increasingly inclined downwards towards the transport path 63, which additionally supports the lateral offset. This measure is particularly necessary when the distance between the drivers 49 is chosen to be small to increase the transport capacity. Particularly when dispensing sleeves 66, a particularly large time offset is not necessary since the sleeves do not have a large diameter.

In this example, the conveyor belt 64 transports out of the image plane. This avoids an additional change in transport direction and it is also possible to dispense with further guide elements along the belt 64. The conveyor belt 64 is deflected by a deflection roller 64 '. The drive of the conveyor belt is not shown here. The transfer and delivery of the individual carriers 65 on the winding machine side takes place analogously. The transport path 67 is formed by a conveyor belt 68, which is deflected by a deflecting roller 68 '. Guide plates 69 and 70 are provided here, the guide plate 70 having a groove 70 '. Lifting profiles 72 and 72a are arranged on the delivery side of the cops 2 at the transport path 73. The transport path 73 is essentially formed by a conveyor belt 74, which by a Deflection roller 74 'is deflected. The drives of the conveyor belts 68 and 74 are also not shown in detail.

Since the drivers 49 are fastened on the chain 48 at a relatively short distance from one another, a lateral offset during the tilting is also required at the delivery point of the individual carriers 65, which are covered with cops 2. Since at this delivery point cops 2, which have a larger diameter than the sleeves 66, are tilted, a greater lateral offset must take place. This is done here analogously to the transfer side by means of a lateral movement component of the chain 48, which is conveyed by additional chain wheels 54 ″ and 71 ′. It is also advantageous here if the lifting profiles 72 and 72a, with their surface forming the bearing surface for the individual carriers 65, have an increasing inclination towards the transport path 73. If necessary, the lifting profile 72a can also have an additional vertical edge 72a ', which further improves the guidance of the individual carrier 65.

The pallets 65 have a base 65 'which carries the arbor for the cops 2 or sleeves 66. The base 65 'is connected to a casing ring 65' '' via spokes 65 ''. In this example, only three spokes 65 '' are arranged.

When forming the spokes of the individual carriers, it is necessary to chamfer them from the bottom so that the respective driver can easily enter the opening formed between the spokes.
