Description

k) UI 533 'P51 As the width of the roll grows, so does the sleeve length. A sleeve less than four meters long is transported according to known technology with the axis of rotation in a horizontal position, generally in a gutter which is open in its upper part, from the lower to the upper floor. In this way, it has been possible to minimize the number of necessary movements / transport operations. Transport of a sleeve that is over five meters long in a similar way is often impossible. The load-bearing structures of the buildings are generally dimensioned so that a sufficiently long opening cannot be accommodated in the floor at reasonable costs, ie without reinforcements.

Wiring and cable ladders and other deadly equipment give rise to further restrictions. All changes give rise to costs.

The orientation of the sleeve in the horizontal plane on the lower floor is determined by the location of the cutting equipment and on the upper floor the sleeve / sleeve set must be allowed to reach the roller cutting machine in the orientation required by the roller cutting machine. Often there is also no room to change the orientation of a sleeve / a sleeve set that is over five meters long / long by known means.

They are also constantly trying to increase the factories' production capacity. If the same department for sleeve manufacturing serves your rolling cutters, in today's situation you often have to lift hundreds of sleeves per hour to the machine plane. The feed chute's feed chute is typically six, up to seven meters above the casing's feed conveyor. In order to achieve the required capacity, you must transport fl your sleeves at a time on the vertical conveyor as the so-called miniset. If the length of the mini-seat is, for example, half a movement, space problems can arise in situations with a change of direction.

When transporting sleeves, it is advantageous from the point of view of the control system to maintain the same order as that in which the sleeves have been cut. This can increase the number of turns that must be arranged in the transport path. For capacity reasons, the sleeves often have to be turned as a mini set.

UI 30 533? 5'l Transport of sleeves in a paper mill is described in the presentation www.corelink.se. Lifting solutions for elongated objects are described in the publications SU 870352, EP 1006330 A and WO 2004007336 A.

For the reasons described above, automatic movement of long sleeves and the miniset from one floor to another and turning with known methods give rise to great difficulties.

The object of the invention is to bring about improvements in these disadvantages. A transport system for sleeves between floors can be realized without large openings in the floor. The necessary turns of the conveyor can be performed even in tight spaces. Expensive structural engineering changes and replacements of existing equipment are avoided. The transport device as such is simple and advantageous in price.

Summary of the invention According to the invention, this object can be achieved by transporting the sleeve / sleeve set in the container of the transport member or held by its gripping means so that the order of the sleeves can not be mixed together during transport. The transport of the sleeve / sleeve set can be realized as a combination of cycles of linear movements, possibly also along a route in several steps to its destination. During the journey, grip changes can also be performed with the transport means.

More precisely, the invention is characterized by what is stated in the characterizing parts of the independent claims. In the following, the invention is described with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS In the automatic system according to Figure 1, the sleeve set consisting of the sleeves 1a, 1b, 1c is held by the conveyor means 3 of the conveyor 2 which is shown on the lower floor immediately after the loading of the sleeves. The sleeves have, for example, been conveyed to the transport means by rolling. When the gripper of the conveyor has been closed with the sleeves in its grip, the conveyor is turned to a substantially vertical position 3 ', which is shown in dotted lines. After this, the transport means is lifted up through the opening in the floor 4 to the upper plane.

The transport member 3 is connected to a carriage 5, advantageously via one or more of its turning units. The power unit 6 turns the transport means about the vertical axis via the shaft 7 which is mounted on the carriage. At the upper end of the shaft 7 there are loops 8 fixed in the bearing of which the intermediate part 11 is rotated about the shaft 9 by means of the force unit 10. The conveying means 3, which is connected either directly or via the wind unit to the intermediate part, is pivoted with the intermediate part in the vertical plane in the direction of the arrow R1. Between the intermediate part 11 and the transport member 3 there can also be a turning unit, most advantageously a pure power unit 12, which pivots the transport member about its longitudinal axis from the receiving position to the delivery position and vice versa. In the carriage 5 there are bearing units 13, with which the carriage moves substantially vertically under the control of guides 15 attached to the frame 14. The power unit 16 moves the carriage by means of a toothed belt 17 or corresponding power transmission.

The slide 5 "is shown with dotted lines in the upper position. The conveyor gear 3" is shown with solid lines, in section, facing the direction of observation. The sleeve 1 'is still held by the jaws 18 of the gripper of the conveyor, but the conveyor has already been pivoted to the unloading position 1 \ J Un DJ' Jl 533? 5 '| nen. The transport means and the receiving position on the lower floor, the position before the vertical transport and the delivery position on the upper floor can be located anywhere in the horizontal plane within the framework of a sector of 180 degrees. During the transport distance from the lower to the upper floor, the sleeve / sleeve set is lifted in a substantially vertical direction while the sleeve / sleeve set is in a substantially vertical position. By substantially vertical is meant that the angle between "substantially vertical" and vertical is less than the angle between "substantially vertical" and horizontal.

In the embodiments of both Figure 1 and Figure 2, the orientation of the sleeve / sleeve set in the horizontal plane of the receiving station on the lower floor may be different than in the delivery station on the upper floor. In the embodiments according to Figure 2, the orientation of the transport means in the horizontal plane can be any. The transport means 3 pivots around an entire circle in the horizontal plane, if necessary even more, in the direction of the arrow R2. Also in this embodiment the carriage 5 of the conveyor 2 slides substantially vertically under the control of the guides 15 attached to the frame 14. Via the turning circle 19 a bracket 20 is connected to the carriage 5, to which bracket a slide 22 is connected, most advantageously via a turning unit 22.

The turning unit can advantageously consist of a pure power unit 21. The guides 24 which are attached to the side of the transport means slide under the control of the bearing units 23 of the slide 22 in the direction of the arrow L1. In this way, the transport means 3 moves horizontally in relation to the carriage 5. The power unit 21 pivots the slide and with this the transport means 3 in the vertical plane according to the arrow R1.

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

The versatile movement alternatives as well as the possibility to link and / or make movements simultaneously make it possible to transport the transport body to its destination, even past many obstacles.

Figures 3, 4 and 5 show an advantageous embodiment of the transport member in different phases in cross-section in the transverse direction. The transport member 3 in question which transports the sleeve / sleeve set is loaded from above, straight or obliquely from above, and unloaded from below, straight or obliquely downwards. In Figure 3, the conveyor means is in the receiving position. The dispenser has just fed a sleeve 1 or a sleeve set from the roller table into the storage means of the transport means. Upper locking means 22 mounted in loops 21 attached to the frame 20 are pivoted to the open position. Lower locking means 23 located on the opposite side of the transport means are in closed position.

Figure 4 shows the transport means in the transport position. All locking means are in the closed position. The same figure shows the location of a small-diameter sleeve in the conveyor with dotted lines.

Figure 5 shows the transport means with the lower locking means in the open position. After the lower locking means have opened, the sleeve 1 has fallen down into the groove 24, along which the pusher 25 pushes the sleeve forward to the next station.

Figure 6 shows an embodiment of the invention which enables a change of grip. The sleeve set 1a, 1b has been pushed along the chute 24 by means of the pusher 25 and threaded over the hand transport member 26. A transverse representation of the chute and the pusher is shown in figure 5. The ejection member 27 is retracted to the left in the retracted position. After this, the force unit 29 attached to the frame pivots the male transport means about the shaft 30 to the position 26 ', in the direction of the arrow R1.

Thereafter, the ejection means extends to the position 27 'while pushing the sleeve set in front of it into the female transport means 31. Thereafter, the stop means 32 rotates the clone / claws in front of the sleeve 1a' and the male transport means 31 continues to transport the sleeve set. The hand transport means 26 is most advantageously a commercial linear module, the angular connection points of which, when needed, are covered to enable the sleeve to slide unhindered. The l-lon conveyor 31 is most advantageously a tube which opens helically around the longitudinal axis. The embodiment shown enables a very fast transport of sleeves in the vertical direction, since the weights to be set in motion are minimal in addition to the sleeves.

Within the framework of the reinforcement tank, it is also possible with many other embodiments to automatically move sleeves / sleeve sets from a lower to an upper floor. In addition to the single conveyor shown in Figure 1, or the transport device alternative shown in Figure 6, formed by two successive conveyors, the transport can for instance also be realized as a transport device formed by your interconnected conveyors.
