Description

Reel Handling Device
The present invention relates to a reel-handling device, according to the preamble of Claim 1, for facilitating the transfer of reels over the gap between two consecutively arranged conveyors.
In paper mills, conveyors used for transporting reels are generally of an endless type, which is implemented as either a belt or a lamel conveyor. A gap is formed between two consecutively arranged conveyors, in which neither conveyor properly supports a narrow reel travelling from one conveyor to the next. The width of the gap depends on the radius of the curvature, which is used to turn the belt or chain over at the return or drive end of the conveyor. The radius of curvature of a belt conveyor is less than that of a lamel conveyor, but due to its other properties, it is not advantageous to apply a belt conveyor, particularly for transporting unpackaged paper reels. The radius of curvature of the more usually used lamel conveyor depends on the size of the lamels; a lamel with a short link will also have a small radius of curvature. However, short-link lamel conveyors are expensive, and the types presently in use are not able to satisfactorily transfer reels less than 400-mm wide over the gap between two conveyors. In addition, the surface layers of the reels may be damaged at the gap, due to the angular acceleration arising when the conveyors curve and to the jerking movement acting on the reels. At the gap between the conveyors, the surface pressure acting on the reels is distributed unevenly, which can also damage the surface layers of the reels.
A solution is known from FI patent 108221, in which a three-roller changeover conveyor equipped with a belt is used. In practice, the belt solution in a three-roller form has not shown itself to be wear-resistant.
The present invention is intended to create a new type of device, by means of which the problems described above do not appear.
The invention is based on a changeover conveyor, which comprises at least one conveyor roll and a lamel chain surrounding it, being located in the gap between the conveyors. According to one preferred embodiment of the invention, the conveyor roll is situated on the supper surface of the device.
According to a second preferred embodiment, the conveyor roll is located on the lower surface of the device and is equipped with sprockets for driving the lamel chain. It is preferable to use two support rolls carrying the lamel chain at the turnover ends of this solution. The support rolls can be fixed or rotating.
More specifically, the device according to the invention is characterized by what is stated in the characterizing portion of Claim 1.
Considerable advantages are gained with the aid of the invention.
The device according to the invention can be used to transfer narrower reels over the gap between two conveyors than when using the solutions presently in use. In addition, reels can be transferred over the gap using a finer loading than previously, so that the surface layers of the reel will not be damaged.
A lamel chain is more practical and durable than the belt solution according to the prior art.
According to one preferred embodiment of the invention, by placing the conveyor roll in the lower part of the device, the apparatus is made more reliable, when the forces acting on the drive roll are reduced. By implementing the power transmission with a sprocket, the power transmission too is made more reliable, especially with narrow reels.
hi the following, the invention is examined in greater detail with the aid of the accompanying drawings.
Figure 1 shows a top view of one embodiment of the device according to the invention.
Figure 2 shows a side cross-section of the embodiment according to Figure 1.
Figure 3 shows a side cross-section of an alternative embodiment according to Figure 1. According to Figure 1, a lamel chain 2 surrounds the conveyor roller 1. The roller 1 is rotated by means of a chain attached to a sprocket 3 at the end of its shaft 11, or a similar power-transmission element. The sprocket 3 receives its drive power from the preceding or following proper conveyor. The sprocket 3 typically receives its drive power from the preceding proper conveyor. The roller 1 is supported at both ends by bearings 5 in the device frame 4. A normal type of bearing housing can be used in the bearing of the roller
1. Installed around the lamel chain 2 is a guide plate 6 attached to the frame 4, in the middle of which is a rectangular hole, which is slightly larger than the lamel chain 2 and the edges of which position the lamel chain 2 in its direction of travel.
As can be see from Figure 2, the conveyor roller 1 is in contact with the lamel chain 2, when the piece being transported presses down with its mass on the conveyor chain 2. The piece being transported then presses against the conveyor roller 1 through the lamel chain 2, which connects the drive, on the basis of the friction arising in the lamel chain
2. Once the drive is connected, the lamel chain 2 moves along its track, driven by the conveyor roller 1, so that the lamel chain 2 is in contact with the turnover ends 7 and moves relative to them. The turnover ends 7 are made from steel or a material with corresponding properties, which will withstand the wear caused by the sliding of the lamel chain 2.
As can be seen from Figure 3, the drive between the conveyor roller 1 and the lamel chain 2 can also be implemented by means of sprocket contact, in which case there is a ' sprocket 8 in the conveyor roller 1, the teeth of which penetrate between the joints of the lamel chain 2 and transmit drive to it. In this case too, only the conveyor roll 1, and more specifically its sprockets 8 transmit drive to the lamel chain 2, so that this moves relative to the carrier rollers 12, the purpose of which carrier rollers 12 being to give an advantageous shape to the lamel chain 2. A support plate 13, against which the lamel chain 2 presses, is located between the carrier rolls 12. As an alternative to the fixed carrier rollers 12, they can be made to rotate, in order to reduce friction. In this embodiment, the conveyor roller 1 is located in the lower part of the device, at a distance from the lamel chain, so that it is thus not in a direct force contact with the paper, pulp, or board reels being moved. Alternatively, the sprocket 8 can be in the upper part of the changeover conveyor and can be in toothed contact with the lamel chain 2, in which case the support plate 13, is located at the lower end of the changeover conveyor, whereby it also acts as a tensioning plate.
The present device can also be used for separating reels. When the first reel of a group of reels coming from the slitter-winder arrives from the preceding proper conveyor 9 on top of the lamel chain 2 of the changeover conveyor located between the proper conveyors 9, 10, the preceding proper conveyor 9 is stopped, whereby the reel on top of the lamel chain 2 continues to travel to the following proper conveyor 10, while the other reels remain on the preceding proper conveyor 9. After this, the preceding proper conveyor 9 is restarted, whereby the next reel in the group moves onto the lamel chain 2. After this, the preceding proper conveyor 9 is stopped again, whereby the reel on the lamel chain 2 continues to travel onto the following proper conveyor. The same procedure is repeated for each reel in the group of reels.
The invention can also have embodiments differing from those described above.
