CLAIMS
1. A roll material handling arrangement comprisin a support for a plurality of rolls and circulating mean for circulating said rolls with respect to a rol transfer arrangement at which rolls can be transferre between the circulating arrangement and a utilisatio point.
2. An arrangement according to claim 1, in whic the circulating means comprise horizontal beams wit depending hangers for the ends of the rolls, the beam being mounted to endless belt, chain or like circulatin carriers trained on guides.
3. An arrangement according to claim 2, comprisin drive means for circulating the endless belt, chain o like carriers on the guides.
4. An arrangement according to claim 2 or claim 3 in which the transfer arrangement comprises track mean interposable with the circulating means to support roll to be transferred so that it can be freed of th hangers and moved on the track means away from th circulating means.
5. An arrangement according to claim 4, ' in which at a location on the track means remote from the circulating means are hangers to support a roll in readiness for transfer out of the arrangement.
Description:
ROLL MATERIAL HANDLINGARRANGEMENT

This invention relates to roll material handling arrangements, particularly to arrangements for handling rolls of textile material on centres, for example for loading on to cloth spreading machinery.

An example of a roll material handling machine for feeding roll material on to and removing empty centres from cloth spreading machinery is a Kuris (RTM) hoist, which comprises a pivoting arm arrangement which can be lowered, e.g. to ground level, so that the ends of a roll can be set into forks on the ends of the arm arrangement and lifted therein to be set into roll holding rollers of a movable carriage of the cloth spreading machine.

Such an arrangement is capable of handling onl one roll at a time and requires operator attention in order to remove an empty roll centre from the clot spreading machine and replace it with a full roll.

The present invention provides a more efficien arrangement and one which lends itself to automati operation.

The invention comprises a roll material handlin arrangement comprising a support for a plurality o

rolls and circulating means for circulating said rolls with respect to a roll transfer arrangement at which rolls can be transferred between the circulating arrangement and a utilisation point.

The circulating means may comprise horizontal beams with depending hangers for the ends of the rolls, the beams being mounted to endless belt, chain or like circulating carriers trained on guides. The arrangement may comprise drive means for circulating the endless belt, chain or like carriers on the guides. The transfer arrangement may comprise track means interposable with the circulating means to support a roll to be transferred so that it can be freed of the hangers and moved on the track means away from the circulating means.

At a location on the track means remote from the circulating means, hangers may be arranged to support a roll in readiness for transfer out of the arrangement.

One embodiment of a roll material handling arrangement according to the invention will now be described with reference to the accompanying drawings, in which :-

Figure 1 (prior art) is an elevation of a conventional Kuris (RTM) hoist;

Figure 2 (invention) is a side elevation o the embodiment;

and Figure 3 is a front elevation of th embodiment.

In the Kuris (RTM) hoist arrangement illustrate in Figure 1, a pair of arms 19 pivoted about horizontal axis 27 move between a loading positio (broken line) at which a roll of fabric 23 can be loade into the forks 22 on the ends of the arms 19 and transfer position (full line) in which the roll i transferred to roll support means 11 comprising roller 12 supporting he ends of the roll centre. The roller 12 are in a movable carriage 14, having a utilisin position 15 in which the roll is positioned fo threading up and use on the spreading machine, and firs and second transfer positions 16,17 in which rol transfer operations are carried out.

To change a roll, the arms 19 must be placed i the transfer position to receive the empty centre of th spent roll from the rollers 12, then pivoted down to th loading position for the centre to be removed from th

•" •# forks and taken away. A fresh roll of fabric is engage in the forks and the arms 19 pivoted back up to th transfer position.

The roll material handling arrangement according to the invention, illustrated in Figures 2 and 3, comprises a support 31 for a plurality of rolls 32 and circulating means 33 for circulating said rolls 32 with respect to a roll transfer arrangement 34 at which rolls can be transferred between the circulating means 33 and a utilisation point 35.

The circulating means 33 comprise horizontal beams 36 with depending hangers 37 for the ends of the rolls, the beams 36 being mounted to endless belt, chain or like circulating carriers 38 trained on guides 39. The hangers 37 are movable along the beams 36 to accom¬ modate different roll widths. The arrangement comprises drive means in the form of a motor 41 connected to one or more sprockets, pulley wheels or the like 42 by means of chain or belt transmission 43 for circulating the endless belt, chain or like carriers 38 on the guides 39.

The transfer arrangement 34 comprises track means 44 interposable with the circulating means 33 to support a roll 32 to be transferred so that it can be freed of the hangers 37 and moved on the track means away from the circulating means 33.

At the location 35 on the track means 44 remote from the circulating means 33 are hangers 37 to support a roll in readiness for transfer out of the arrangement,

for example on to the rollers 12 of the carrier 14 of spreading machine as illustrated in Figure 1.

The track means 44 may be movable towards an away from the circulating means 33 so that, for transfe of a roll, the ends 44a of the track means 44 are withi the paths of the ends of the roll centres and th circulating means 33 operated so as to lower a selecte roll so that its ends lie on the ends 44a of the trac means, the circulating means then moving the hangers 3 downwardly clear of the roll. The roll is then move along the track means 44 to the end location 35 wher the hangers 37 are on a beam 46 which is mounted o pivoted arms 47, these arms 47 pivoting to enable th hangers 37 to be located under the ends of the rol centre so as to lift up the roll from the track 44 whe the beam 46 is pivoted back up.

It will be appreciated that, as compared to t conventional roll handling arrangement of Figure 1, t arrangement according to the invention provides f substantially greater roll storage capacity, wi increased flexibility inasmuch as, in the embodime illustrated, eight roll carrying beams 36 are provide which can easily be loaded with rolls from ground leve or indeed from any other level, and which can be mov selectively to the transfer position. There is even t

possibility of utilising parts of rolls, retaining a part empty roll in the circulating system until needed again.

Operation of the system is fast because of the ready availability of rolls in the system and the ease of operation which reduces transfer time considerably as compared to the conventional hoist arrangement.

The motor can be under the control of a computer in a computer integrated manufacturing system, actuators, not shown, being provided to carry out the picking-up and roll releasing operations of the hangers 37.

The arrangement can be readily configured to spreading machines of different design as by adapting the height of the transfer arrangement 34 relative to the support 31.
