Definitions
- the present invention relates to a storage arrangement for empty cores for the reel-up in a paper machine in which paper is manufactured in a continuous web which is wound onto said empty cores in the reel-up to form reels of paper, said storage arrangement comprising a stand including a container for empty cores and a feed-out ramp for said empty cores from the container, the container having a top, a bottom and four preferably vertical sides arranged in pairs opposite each other and comprising a front side facing the feed-out ramp, a rear side facing away from said ramp, and two parallel sides arranged in the feeding direction of the ramp, said four sides between them defining a space for empty cores, which container also comprises an upper inlet opening and a lower outlet opening in conjunction with the upstream end of the feed-out ramp.
- the first method uses an empty reeling drum, also termed core shaft, for production of coreless paper reels, while in the second alternative a hollow core is applied on said reeling drum in the form of a non-deformable cylindrical sleeve, preferably of cardboard.
- the core usually consists of a tube built up of a multi-layered wall of wound paper which has been laminated with a suitable binder such as water glass .
- the diameter may generally reach approximately 40-50 cm.
- the paper web is secured to the core, usually with the aid of a strip of adhesive or tape.
- new reeling drums are constantly supplied with empty cores from some type of store, also known as the core shaft stock.
- This stock is preferably arranged close to the surface winding drum at the upstream end of the reel-up, and suitably at a level just above the production line of the reel-up in order to save space. The stock must then be continuously replenished as the reeling drums with the cores are used up by the reel -up.
- the shearing member is usually arranged immediately downstream and immediately adjacent the drive side of the reel -handling section of the reel-up, i.e. on the side where the cores are fed in, so they can be returned as the finished reels are taken care of by a transport arrangement provided there, e.g. a sliding carriage or conveyor belt, and removed to the next work station which is generally some type of conversion equipment.
- the paper cores are also recovered from the paper reels, said cores being placed in an intermediate store consisting of some form of transport container so that they also are re-used, as return cores, in the production of paper reels.
- said return cores are then taken, manually or using a work vehicle, to a storage arrangement for empty cores where the cores are either emptied from the transport container directly down onto the feed-out ramp, or down into some form of substantially vertical storage container for cores, a core stock, fitted at the upstream side of the feed-out ramp.
- the storage arrangement for new empty cores is generally located at the end of the production line, in conjunction with said feed-back station and is thus easily accessible to the above-mentioned work vehicle.
- the empty cores are fed one at a time to a width corresponding to the width of the paper web, to a lifting table arranged between the two stand parts of the reel -up, after which the reeling drum last withdrawn is again introduced into the empty core(s), by the above-mentioned shearing device, and thus forms a reeling drum ready for reeling.
- the finished reeling drum is then moved to the above-mentioned stock of reels so that the process can start again and thus progress continuously.
- the truck driver after moving the transport container filled at the conversion equipment to the storage arrangement for empty cores, the truck driver must manually empty the empty cores from the transport container down onto the feed-out ramp or down into the storage arrangement above said vertical core store. To perform this tedious work, the driver is forced to get down from his truck and then activate the actuator for the container's outlet hatch. Due to the problem described above, of empty cores landing crookedly in the container and thus being clamped, the driver must carefully check the position of the empty cores inside the container after each delivery before activating the actuator for the outlet hatch.
- the object of the present invention is to provide an improved and simplified storage arrangement for empty cores for use in a reel-up in a paper machine in which paper is wound onto said empty cores to form paper reels, in which filling and feeding out the empty cores from the storage arrangement is greatly improved.
- Another object of the invention is to provide a storage arrangement which is self-emptying.
- a third object of the invention is to provide a storage arrangement having a magazine that ensures feed-out of the empty cores without risk of their being damaged, being clamped or jamming during said feed-out in the magazine itself or during transfer to the feed-out ramp.
- Another object of the invention is to provide a storage arrangement allowing a better ratio between the volume and height of the container and the maximum number of empty cores stored therein.
- Yet another object of the invention is to provide a storage arrangement having an empty core magazine that allows the contents to be inspected and checked from the outside .
- the arrangement according to the invention is characterized in that a plurality of downwardly inclined planes are arranged one beneath the other inside the container and are directed alternately from the front side and the rear side of the container, each plane having a downstream end located a predetermined distance from the adjacent rear side or front side to provide an opening therebetween so that each empty core rolling down an upstream plane continues freely to the next plane in a continuous path of moving empty cores from the inlet opening to the outlet opening, and that said stand also includes a stand table, at which the container is arranged in conjunction with the feed-out ramp in exchangeable manner to enable transport of the container to a filling station.
- the advantage is gained that the driver of a truck, for instance a slat or fork-lift truck, can see right through the magazine container without obstruction from at least two of its sides and can thus see where he is driving.
- a truck for instance a slat or fork-lift truck
- the empty core magazine being designed in a manner described below so that it is at least partially see-throughable, which also offers the additional advantage of being able to inspect the empty cores.

- Figure 15 shows a side view of the storage arrangement according to Figure 1, with an alternative embodiment of the feed-out ramp where said ramp abuts the container on a level with its outlet opening.
- Figures 1 and 2 show schematically, in perspective and side view, respectively, a storage arrangement 1 for non-deformable cylindrical empty cores 2 intended for use in a reel-up 3, see Figure 3 , of a paper machine in which paper is manufactured in a continuous paper web.
- Paper reels 4 are wound continuously in the reel-up 3 on a body comprising a reeling drum 5 and a core applied thereon in the form of the above-mentioned non-deformable cylindrical empty core 2.
- the reel-up 3 comprises a stand member 6 having first and second identical, elongate, parallel stand parts 7, 8 along which the finished paper reels 4 roll on rails 9 arranged on each stand part 7 and 8, respectively.
- a reel-handling part 10 takes over the finished paper reels 4 and conveys them further to some form of transport means, not shown, such as a sliding carriage or conveyor, which receives the paper reel 4 and conveys it to a store or conversion equipment , not shown .
- a stock of drums is arranged upstream of the reel-up in Figure 3 and above the stand member 6, containing reeling drums 5 with empty cores 2 applied. New reeling drums 5 are lifted down from this stock by means of lowering arms, not shown, to the reel -up 3 where the process of reeling the paper web to a finished paper reel 4 commences .
- Said stock of drums is filled with new reeling drums 5 by means, not shown, located upstream of said stock.
- the finished paper reels 4 are tipped over to the transport device, after which a new empty core 2 is rolled down from a feed-out ramp 14 pertaining to said storage arrangement 1 to a lifting table 13 whereupon, after a sufficient number of cores 2 to achieve the requisite web width of the paper web have been applied on said reeling drum 5, it is again conveyed to said drum stock in a manner not shown.
- a stock 15 of empty cores is situated on said feed-out ramp 14 between two lengths of guide plates 29 arranged close to each long side of the ramp 14.
- the feed-out ramp 14 is given sufficient inclination to ensure that the empty cores 2 roll automatically and continuously down one after the other, along the inclined plane of the ramp 14 and the lowermost empty core 2 then rolls over to the lifting table 13 in the manner described below.
- one or more strips 28 are arranged on the feed-out ramp 14 (see Figure 6) extending from the upstream end of the ramp 14 to its downstream end, in order to effectively prevent the empty cores 2 from being impeded by any debris that may have accumulated on the ramp 14.
- a separation device 30 rotatable about a shaft, see Figure 2, which may be in the form of one or more elements 35 rotatable about said shaft by means of actuators 34, said elements 35 comprising one or more protrusions 31 such as spokes, against or between which each empty core 2 lowermost in the direction of feed of the ramp rests and after or during rotation of the element 35 is imparted a rolling movement downstream. Thanks to this separation device 30, as the lowermost empty core 2 rolls over to the lifting table 13, the next empty core 2 is retained by one or more of said protrusions 31.
- a barrier 32 is arranged comprising an upper restraining device 33, e.g. a metal sheet, acting as a stop to prevent the lowermost empty core 2 from rolling over the restraining element 35, and also preventing any similar climbing of the following empty cores 2.
- said restraining device 33 together with said separation device 30, effectively regulates feed-out of each individual empty core 2 and prevents more than one core 2 from being fed out at a time.
- the storage arrangement 1 includes control equipment, not shown or described in detail here, of pneumatic or electric type, including requisite sensors of some conventional type, at the inlet and outlet openings to the storage arrangement 1, e.g. at the inlet and outlet to the feed-out ramp 14.
- the storage arrangement 1 also comprises a stand 16 consisting of three parts, i.e. said feed-out ramp 14, a stand table 17, see Figure 14, and a container 18 for refilling with new empty cores 2.
- this movable and exchangeable container is formed by a rectangular, box-shaped, open magazine basket 18.
- the term "open” is used here to indicate that the contents can be inspected from the outside of the container 18 which may be composed, as in the shown embodiment, of a frame of horizontal, vertical and diagonal connecting elements, stays or rods 19, preferably of metal, or may consist of a mesh or grid construction, preferably of steel, enabling free vision through said container 18.
- the magazine basket 18 comprises two suitably horizontal sides consisting of a top 38 and a bottom 39, and four preferably vertical sides arranged in pairs opposite each other and comprising a front side 20 facing the feed-out ramp 14 and a rear side 21 facing away from said ramp 14, and two parallel sides 22, 23 in the feeding direction of the ramp 14, said four sides between them defining an open space for empty cores 2, which container 18 also comprises an upper inlet opening 24 and a lower outlet opening 25 located preferably in the upper 38 and lower side 39, respectively, that latter opening 25 adjoins the upstream end of the feed-out ramp 14.
- the magazine basket 18 also comprises a plurality of level -forming, downwardly inclined planes arranged one beneath the other in the open space of the container 18 in a zig-zag pattern seen from the sides 22, 23, as described below.
- These planes are preferably made of flat sheets of thin sheet, metal, metal mesh, rods or grids.
- Said planes 26 commence from the front side 20 or the rear side 21 of the magazine basket 18, where they are firmly secured in suitable manner, e.g. by means of a welded joint or some other suitable connection such as screw or rivet joints.
- the inclined planes 26 extend across the open space of the magazine basket 18 in downward direction, extending alternately towards said front side 20 or rear side 21 of the container 18.
- the downstream ends of the alternately inclined planes 26 terminate a short distance from each opposing inner side of the container 18. Said short distance forms an opening 27 between the downstream end of the plane 26 and the inner wall of the container 18.
- the empty cores 2 lying horizontally and parallel to each other in the magazine basket roll down said planes and fall freely down from the downstream end of each plane 26 onto the next inclined plane 26 through said opening 27, which has been given somewhat greater dimension than the diameter of the empty cores 2.
- the diameter of this type of empty core 2, intended for paper reels may be as much as 40-50 cm.
- FIG. 13 An alternative embodiment of the exchangeable magazine basket 18 is shown in Figure 13 and includes spacers 47 arranged on each plane 26 along one or both sides 22, 23 so that the free distance between said sides 22, 23 can be adjusted to predetermined lengths of empty cores.
- Said spacers 47 are preferably made of sheet metal which is bent to suitable form, e.g. U-shaped as in the shown embodiment shown, so that said metal sheets provide a ridge or edge along which the empty cores 2 can roll.
- one or more opening devices 42 are arranged (see Figure 13 or Figure 1) which include a closing member 43 such as a gate, flap or hatch, arranged pivotably or slidingly by suitable journalling means or, as in the shown embodiments, or one or two blocking devices 44 which block (s) the outlet opening 25 and also an actuator 45 for said closing member 43, preferably arranged vertically.
- This actuator 45 may suitably consist of a cylinder 46, in the preferred embodiment a pneumatic cylinder 46, since there is then no risk of hydraulic oil leaking onto the empty cores 2.
- Figure 13 shows a vertically displaced closing member 43 comprising only one actuator 45, the member 43 in the embodiment shown being shaped as a curved plate at its lower end and its vertical sides running in vertical guides. If only one actuator 45 is used there is no need for synchronization with other actuators 45.
- the opening device (s) 42 for the container 18 is/are designed as described below so that the container 18 is automatically self-emptying when the empty cores 2 are placed correctly on the stand table 17.
- the arrangement of such automatic opening means 42 limits the number of work phases for the truck driver who no longer needs to get out of the truck to manually empty the container 18. This considerably simplifies the procedure of refilling with new empty cores 2.
- connectors 40 are arranged at the stand 16, comprising a number of guide means 41 and connection means for the closing members 43 of the container 18 so that, with the aid of the slat truck, for instance, the container can easily be mounted on the stand table 17 and, when the container 18 has been fitted onto the stand 17 with the aid of said guide means 41, see Figure 14, it is connected to the compressed air valve on the connection means, not shown, so that when the magazine basket 18 has assumed its correct position, the cylinders 46 and closing members 43 above said cylinders will be activated, whereupon the empty cores 2 can roll out through the outlet opening 25, down onto the feed-out ramp 14.
