METHOD AND EQUIPMENT FOR TRANSPORTATION OF SHELLS

The invention relates to a method for conveying cores which function as a reel core of a paper or board reel in substantially 5 vertical directions. The invention also relates to apparatus for carrying out the method.

The cores are conveyed from the core preparation area to the winders manually in the wagons or automatically by a system formed by several successive conveyors 10. The winders are generally located at the upper, so-called machine plane. Socket preparation is generally, for space reasons, placed at a lower level. In this way, up to ten meters long parent sleeve bundles can be moved from the truck to the warehouse and cut off without the parent sleeves having to be transported over different layers.

Paper mill buildings and mill logistics have been planned in due course, without taking into account any changes that may occur in the distant future. Forecasting is therefore difficult, as the paper mill • · * · can have a life span of over one hundred years. The need for change has been created in particular by t · · / ": the development of 20 printing presses, which has recently accelerated.

In order to improve printing efficiency, printing machines that use an increasingly wide web • · · * ··· are constantly being developed. Of course, paper mills must be able to produce a sufficiently wide paper web. For example, • · • ·· I ···. The paper mills that were built 40 years ago are • · • * *. 25 production machinery still modern and efficient. However, they are • · ·. ···. for post-winder roller logistics and core system φ · ·. ] ·. dimensioned by a roll up to four meters wide.

• · · • · · · 118892 2

The current width of the so-called jumbo roll is about 4.35 m, and a generation of printing press is being developed, which already requires a paper web about 4.85 m wide. Presumably, at least one additional step S of equal size proceeds further from here. Indeed, new mills are currently planned for a roll width of approximately 5.4 meters. The same goal is often set for modem projects in existing factories.

As the roll width increases, the length of the sleeve increases accordingly. A sleeve less than 10 meters in length is conveyed by a known technique in a horizontal position with the axis of rotation, usually in an open trough of the upper half, from the lower to the upper layer. This has minimized the number of movements / transfer operations required. It is often impossible to carry the cores longer than five meters in a similar manner. The supporting structures of the buildings 15 are generally dimensioned such that a sufficiently long opening cannot be opened at a reasonable cost, i.e. without reinforcement.

Additional restrictions include pipe and cable racks and other existing: * · *: existing equipment. Any changes will incur costs.

• 20 · The orientation of the sleeve down in the horizontal plane is determined by the position of the cutting equipment • · · *. * "*, And the sleeve / sleeve set at the top must be brought to the winder. To change the orientation of a sleeve / sleeve set more than five · * ·,. meters by well known means of rotation, there is often no space.

Efforts are also being made to continuously increase the production capacity of the mills.

m: If several winders are served by the same core preparation department, • · 3 118892 nowadays often has to raise hundreds of cores per hour at the machine level. The winder feeder trough is typically six, up to seven meters above the core cutter feeder conveyor. In order to reach the required capacity, the vertical conveyor has to transport 5 multiple cores at a time in so-called mini-sets. For example, if the length of the minisettle is half the length of the move, space problems may arise in the case of reversal situations.

When transporting the sleeves, it is advantageous for the control system to maintain 10 the same order in which the sleeves have been cut. This can increase the number of turns to be tracked along the route. Capacities often have to be turned in miniature sets.

Carriage of cores at the paper mill is described in presentation 15 www.corelink.se. Lifting solutions for elongated objects are described in SU 870352, EP 1006330 A and WO 2004007336 A.

The object of the invention is to bring improvements to these disadvantages.

The interlayer core transfer system can be implemented without: 1 · .. large openings in the midsole. Necessary turns of the transfer device can be carried out in tight spaces. Avoid expensive construction engineering changes m j, · 1: 25 and reorganization of existing installations. Transfer equipment is ·· 1 simple in itself and inexpensive.

This object can be achieved in accordance with the invention by transporting the sleeve / sleeve set in the container of the transport member or in the grip of its gripping member so that the stiffness of the sleeves cannot be disturbed during transport. As a combination of straight-line movements, transportation of 5 cores / cores can be accomplished, possibly in a multi-step route to its destination. Alterations of the transport member can also be made along the way.

More particularly, the invention is characterized by what is set forth in the characterizing parts of the independent claims.

In the automatic system of Figure 1, the core set consisting of the sleeves 1a, Ib, le is located in the grip of the conveying member 3 of the transfer device 2, immediately below loading of the sleeves. For example, the sleeves are introduced by scrolling into the transport member. When the gripper S of the conveying member is closed, the conveyor member is rotated to a substantially vertical position 3 ', which is represented by a dotted line. The conveying member is then raised through the opening in the midsole 4 to an upper level.

Preferably, the conveying member 3 engages the carriage S via one or more pivoting units. The power unit 6 pivots the conveying member about the vertical axis via the shaft 7 mounted on the carriage. At the upper end of the shaft 7 are mounted lugs 8, in the bearing of which the spacer 11 pivots about the shaft 9 by the power unit 10.

Not all power units and transmissions known per se have been described.

Versatile turnover conditions and the possibility of chaining and / or 5 simultaneous movements make it possible to transport the transport body through many obstacles to its destination.

Figures 3,4 and 5 illustrate a preferred embodiment of the conveying member in various transverse sections. 10 The conveyor body 3 carrying said sleeve / cartridge set is filled from above, directly or top-notched and unloaded from below, directly or downwards. In Figure 3, the transport member is in the receiving position. The dispenser has just fed from the scroll table the sleeve 1 or sleeve set into the cradle of the transport member. The upper closing members 22 of the IS mounted on the lugs 21 attached to the body 20 are in the open position. The lower closing members 23 on the opposite side of the conveying member are in the closed position.

In Fig. 4, the transport member is illustrated in the transport position. All closing members ··· • · '···' 20 are in the closed position. In the same figure, a dashed line depicts the position of the small diameter sleeve in the transport member.

Figure 6 illustrates an embodiment of the invention that enables the handgrip to be changed. The sleeve set 1a, Ib is threaded down the trough 24 by the pusher 25 over the male transport member 26. A transverse view of the trough and the pusher is shown in Fig. 5. The discharge member 27 is 5 retracted to the left in the interior position. After this, the frame 28 secured to the power unit 29 to turn the male member transport position 26'akselin 30 at the arrow R direction. Next, the ejector member moves to position 27 ', pushing forward into the female set of conveyor 31. Thereafter, the blocking member 32 pivots the nail (s) into the socket, and the female transport member 10 continues to carry the socket set. Most preferably, the male transport member 26 is a commercial linear module whose angular junctions are cross-linked as necessary to allow the sleeve to slide freely. Preferably, the female conveying member 31 is a tube that pivots about a longitudinal axis. The illustrated IS embodiment allows for very rapid vertical transport of the sleeves, since the displaceable masses in addition to the sleeves are minimal.
