Description

HEADER PRESS
The object of this invention is a header press for pressing outer headers to the heads of a web material reel, for example, a paper, a cardboard or a pulp reel, packaged in a wrapping, into which press the reel is brought and/or transferred forwards in the axial direction of the reel, and which header press comprises press plates for both heads of the reel, in which case a header is placed on both press plates before pressing.
Thus, the invention is especially aimed at an apparatus with which one fastens outer headers to the heads of a web material reel packaged in a wrapping, which is called a paper reel herein in this specification. The wrapping and fastening of an outer header may be done in the same or a different work station.
Previously is known a header press which has a header press plate at the end of an arm for fastening a header. When the press plates of the press are in their initial position, round headers of cardboard are placed on the press plates either manually or automatically. In this known header press, the press plate is fastened to the end of a turning arm, which arm is bearing-mounted from its other end to the machine frame. The press plate turns through its arm with a turning motion to the area of the reel head, where the press fastening of headers is performed in a known manner.
A problem of this known header press is the great mass of the press plate. This problem is especially emphasised with large-diameter paper reels. Because of forces required for moving the great mass of the press plate, the machine structures have to be strong. Implementing strong enough structures is economically expensive.
In addition, a problem of this known header press is the work safety of persons working in its vicinity. The operation of a press plate with a turning motion poses a pinching or an injury risk for the person/persons operating the machine. When the known header press operates, the machine frame, the arm of the turning press plate and the press plate form a clamp-like operation in which eliminating danger requires separate protection measures. Naturally, this increases the costs of the apparatus. As an example of such a header press may be mentioned the apparatus shown in figure 2 of the specification FI/EP 1044882 T3.
A problem in the known header press is also the placing of the header in a precise manner on the surface of the press plate, because the press plate and the alignment point or line in it is in a different position in the initial position than it is in the operating position. By means of the alignment point or line, one may align the header to the right place in the head of the paper reel. When the press plate is in its initial position, the alignment point is in position appr. 0° (3 o'clock) or appr. 180° (9 o'clock). In its operating position, the press plate has turned appr. 90° (6 o'clock) from its initial position.
Furthermore, a problem is that in the turning motion provided with prior-art a hydraulic cylinder is typically used in order to achieve the required great force to move the press plate and its arm. The use of the hydraulic cylinder may cause oil leaks which are harmful to the environment and cause untidiness of the environment which oil leaks are commonly caused by tube and connector faults and the wear and tear of cylinder seals caused by high working pressure.
The aim of the invention is to achieve a header press with which one avoids the press plate turning motion requiring great strengths and the pinching risk endangering work safety, and in which header press the alignment point or line of the header is the same in all operating positions. These aims are accomplished with a header press according to the invention to which is characteristic that at least one press plate is mounted to an arm linearly movable in the transverse direction towards the axial direction of the paper reel.
It is characteristic to an advantageous embodiment of the header press according to the invention that the arm of said one press plate is mounted to a carriage movable in the axial direction of the paper reel.
It is characteristic to another advantageous embodiment of the header press according to the invention that the press plate fastening the outer header to the opposite head of the paper reel is fixedly mounted to its place.
It is characteristic to a further advantageous embodiment of the header press according to the invention that the press plate fastening the outer header to the opposite head of the paper reel is mounted to an arm linearly movable in the transverse direction towards the axial direction of the paper reel.
The invention accomplishes a header press with which one avoids the press plate turning motion requiring great strengths and the pinching risk affecting work safety and in which header press the alignment point or line of the header is the same in all operating positions. In a header press according to the invention, the press plate and the arm connected to it move linearly, advantageously in horizontal plane, in which case less force is required for moving the great mass than in the turning motion. Because of lessened force requirement, also the structures may be lighter and thus more cost-effective. In addition, linear motion is simpler and cheaper to implement.
In a header press according to the invention, no hydraulics is required to achieve linear motion. An advantage of avoiding the hydraulics is friendliness to the environment and cost savings. A further advantage is that the extensive service need of the press caused by the hydraulics system is removed.
Next, the invention is described in more detail by referring to the accompanying drawings in which
Figure 1 shows a top view of a header press according to an embodiment of the invention.
Figure 2 shows a top view of a header press according to a second embodiment of the invention.
Figure 3 shows a top view of a header press according to a third embodiment of the invention.
Figure 4 shows a view of a header press according to the invention in the axial direction of the paper reel.
Figure 1 shows thus a header press according to an embodiment of the invention, in which reference designation 9 means a paper reel which is transported with a conveyor 10 in the direction of an axis 11 when the drawing is viewed from right to left to the header press. Another possibility is that the paper reel is brought in the direction showed by an arrow 18a to the header press. In the presented example, the paper reel is already wrapped in a wrapping 8 and the edges going over the wrapping are folded across the head. Similarly, it is possible that the wrapping and/or folding of the edges is performed in the same station as the pressing of the headers. The invention is thus aimed at an apparatus for pressing outer headers to a paper reel. The header press comprises their own press plates 6, 7 for both paper reel heads, which both press plates have their own arms 4, 5 for moving the press plates in the transverse direction towards the axial direction of the paper reel linearly. That is, advantageously in horizontal direction. This direction is marked with arrows 12, 13 in figure 1. In figure 1, the initial position of the press plates 6, 7 and their arms 4, 5 is designated with the letter A and unbroken lines. The press plate 6 moves through the arm 4 from this initial position A to the operating position B in the direction of the arrow 12. The paper reel 9 is transferred in the direction of the axis 11 with the conveyor 10 to be in contact with or in vicinity of the press plate 6. Before this, the headers 17 to be fastened have been placed on the press plates 6, 7 manually or automatically, for example, with a robot in a method known perse, and they are aligned according to the alignment points or lines R (figure 4) in the press plates. The headers 17 may be placed to their place when the press plates are either in the position A or B.
Correspondingly, the press plate 7 moves through the arm 5 from its initial position A to the operating position B in the direction of the arrow 13, that is, in the transverse direction towards the axial direction 11 of the paper reel. In addition, the press plate 7 and the arm 5 move transported by the carriage 3 in the axial direction of the paper reel (arrow 14) into position C in contact with the paper reel 9 and press the paper reel between the press plates 6, 7, in which case the headers 17 are fastened to the heads of the paper reel 9 in a manner known per se, for example, by glue or thermal attachment. After this, the press plates 6, 7, the arms 4, 5 and the carriage 3 return to their initial positions A. The paper reel is transferred forwards either parallel with the axis 11 on the conveyor 10 or transversely by rolling to a direction 18. If the paper reel is transferred forwards or brought to the header press station 1 transversely 18, 18a, the press plate 6 may be fixedly in position B. Then, the header press is of advantageous structure, because no arm 4 or its moving elements are required.
Figure 2 shows an essentially similar header press to figure 1. The only difference is that the path 15 of the press plate 6 and the arm 4 is inclined and runs in direction 15. With this, one achieves that in the return phase the press plate 6 unfastens from the paper reel head (from the fastened header) immediately in an early stage of movement, and does not, thus, drag along the reel head.
Figure 3 shows a further embodiment in which both press plates 6, 7 and their arms 4, 5 are arranged movable also in the direction of the axis 11 of the paper reel. In it, the paper reel 9 is transferred to the header press station 1 with the conveyor 10 in the direction of the axis 11. The press plates 6, 7 are transferred through the arms 4, 5 from the initial position A to the operating position B in the direction of the arrows 12, 13. The carriages 2, 3, into which the arms 4, 5 are fastened, move in the direction of arrows 14, 16 when the press plates 6, 7 move to a position C. Before this, headers 17 to be glued have been placed on the press plates 6, 7 and they have been aligned according to the alignment points R (figure 4). The press plates 6, 7 come in contact with the paper reel 9 and press the paper reel between them, when the headers 17 are fastened to the heads of the paper reel. The arm 4 and the carriage 2 of the other side may move at the same time or at a different time as the carriage 3 and the arm 5 of the opposite side. After this, the press plates, arms and carriages return to their initial positions A. The paper reel 9 is transferred forwards from the header press station either to the direction of the axis 11 or by rolling to the transverse direction 18.
The paper reel may also come to the header press station in the transverse direction 18a and leave in the direction of the axis 11.
It is well known by those skilled in the art that the invention does not limit to the embodiment examples described above, but it may vary within the scope of the enclosed patent claims.
