ENDED CLAMP

The present invention relates to a press of an outer end press on the ends of a roll of material wrapped in a wrapper, e.g. n has an end tag inserted before pressing.

10

Accordingly, the invention is particularly directed to an apparatus for attaching outer end caps to the ends of a roll of web material wrapped in a wrapper, hereinafter referred to as a paper roll in this specification. The wrapping and attachment of the outer end tag can be done on the same or different workstation.

It is known in the prior art to have an end-plate press having an end-plate press plate for attaching the end-tag to the end of the shaft. When the press plates of the press are in their initial position, circular cardboard end tags are inserted into the press plates either manually or automatically. In this known end-press press, the puris-20 tin plate is attached to a pivoting end of the arm, which is supported at one end to the machine frame. The press plate pivots for this purpose by means of a pivoting motion j * to the end of the roll, where the press fastening of the end tags is performed in a known manner.

• # · ♦ ** '·. 25 A problem with this known end-plate press is the large mass of the press plate * * * | e. This problem is particularly accentuated by the large diameter paper rolls. Due to the high forces required to move the press plate, the machine structures must be '· * ·' strong. Implementing sufficiently strong structures is economically costly.

A further problem with this known end-press press is through the press. safety at work for people who work affectionately. Swivel clamp [···. there is a risk of pinching or injury to the person (s) operating the machine. When the known end-to-end press operates, the body of the machine and the pivot arm of the pivoting disc and the press disc form a function similar to a tongue, in which the elimination of danger requires separate security arrangements. This, of course, increases the cost of the hardware. As an example of such an endprint press 2 117196, the apparatus shown in Fig. 2 of FI / EP 1044882 T3 may be mentioned.

In addition, the known end-tag press has the problem of accurately positioning the end-tag on the surface of the press plate, since the press plate and the alignment point or line thereon are in a starting position different from the operating position. The alignment point or line causes the end tag to be positioned at the correct position on the end of the paper roll. With the press plate in its initial position, the alignment point is at about 0 ° (3 o'clock) or about 180 ° (9 o'clock). In its operating position 10, the press plate has turned about 90 ° (6 o'clock) from its initial position.

A further problem is that in the articulated pivot movement, a hydraulic cylinder is typically used to provide the press plate and the high force required to move this arm. Operation of the hydraulic cylinder 15 can result in environmentally damaging and environmentally polluted oil leaks, generally due to hose and connector failures and wear of cylinder seals due to high working pressure.

It is an object of the invention to provide an end patch press which avoids rotating movement of press discs requiring high forces and the risk of crushing endangering occupational safety and wherein the end tag alignment point or line is the same in all operating positions. These objects have been achieved by: an end patch press according to the invention, characterized in that:

Another advantageous embodiment of an end-tip press according to the invention is the following. the shape is characterized by the fact that the opposite end of the paper roll • •. ···. the end plate clamping plate is fixed in place.

···: .i .: 35 Another preferred embodiment of the V ·: end-press press according to the invention is characterized in that the press plate securing the outer end of the paper roll is mounted in a direction movable in a direction transverse to the axial direction of the paper roll.

The invention provides an end-tag press that avoids a high force 5 turning movement and a risk of crushing affecting occupational safety, and in which the end-tag press point or line is the same in all operating positions.

In the end-assist press according to the invention, the press plate and the arm 10 connected thereto move linearly, preferably horizontally, whereby less force is required to move a large mass than in a pivoting movement. Due to the lower force requirement, structures can also be lighter and hence more cost effective. In addition, linear motion is simpler and cheaper to execute.

15

Hydraulics are not required in the end-assist press of the invention to achieve linear motion. The benefit of avoiding hydraulics is environmental friendliness and cost savings. A further advantage is that the high maintenance of the press due to the hydraulic system is eliminated.

Thus, Fig. 1 shows an end patch press according to an embodiment of the invention, in which reference numeral 9 denotes a roll of paper which is conveyed by a ribbon conveyor 10 in the axial 11 direction when viewed from right to left in the end patch press. the possibility of ketones is that the paper roll is brought in the direction of the arrow 18a to indicate the end-shield press. In the example shown, the roll of paper is already wrapped in a wrapping wrapper 8 and the edges of the wrapping wrapper over the end are folded against the end. It is equally possible that the wrapping and / or folding of the edges takes place in the same position as pressing the end tags. The invention thus relates to an apparatus for pressing outer end tags onto a paper roll. Each end roll press includes a separate press plate 6, 7 for each end of the paper roll, each having its own arm 4, 5 for moving the press tabs 10 in a direction transverse to the direction of the paper roll axis. Preferably, therefore, in the horizontal direction. This direction is indicated by arrows 12, 13 in Fig. 1. In Fig. 1, the initial position of the press plates 6, 7 and their arms 4, 5 is indicated by a spinner A and solid lines. The press plate 6 moves from this initial position A into operating position B 12 in the direction arrow 15, through the shaft 4. The paper roll 9 is moved axially 11 in contact with or close to the press plate 6 by the deflector 10. Prior to this, the attachable end tags 17 are manually or automatically placed on the press plates 6, 7, for example by the robot itself and aligned with the synchronization points or lines R (Fig. 4). The end plates 17 can be placed in position 20 with the press plates in either position A or B.

: · '; Correspondingly, the press plate 7 moves from its initial position A via the stem 5 to the function · # *:. to position B in the direction of the arrow 13, i.e. in the direction of the axis of the paper roll 11 seen the transverse direction. In addition, the press plate 7 and the arm 5 move the carriage 3 [· * ·. 25, transported in the axial direction of the paper roll (arrow 14) to position C to contact * the paper roll 9 and squeeze the paper roll between the press plates 6, 7, whereby the end tags 17 attach to the ends of the paper roll 9 in a known manner; eg with glue or heat attachment. The press plates 6, 7, the arms 4, 5 and the carriage 3 are then returned to their initial positions A. The paper roll is moved forward either * · !: in the direction of the axis 11 by the sticker 10 or transversely by scrolling in the direction of 18. If the paper roll is moved end plate press station 1 transversely 18, 18a, the press plate 6 may be fixedly mounted · * ·. In this case, the end-press clamp is inexpensive in design, since there is no need for • · arm 4 and its moving members.

• «* • *

Fig. 2 shows a substantially similar end-press as in Fig. 1. The only difference is that the movement path 15 of the press plate 6 and the arm 4 is oblique and 35 5 117196 runs in the direction 15. This ensures that the return plate 6 is immediately detached from the paper roll end in the initial phase of the movement and thus does not drag along the end of the roll.

Figure 3 shows another embodiment in which both press plates 6, 7 and their arms 4, 5 are also made movable in the direction 11 of the paper roll axis. Therein, a roll of paper 9 is moved to the end-press station 1 and transported 10 in the direction of the shaft 11. The press plates 6, 7 move through the arms 4, 5 from the starting position A to the operating position B in the direction of the arrows 12, 13. The carriages 2, 3, 10 to which the arms 4, 5 are attached move in the direction of the arrows 14,16, whereby the press plates 6, 7 move to position C. Prior to this, glued end tags 17 are placed on press plates 6, 7 and aligned 4). The press plates 6, 7 come into contact with the paper roll 9 and squeeze the paper roll between them, whereby the end tags 17 engage the ends of the paper roll 15. The other half of the arm 4 and the carriage 2 can be moved at the same time or different time as the opposite side of the carriage 3 and the shaft 5. Then, the press plates, arms and carriages return to their initial positions A. The paper roll 9 is moved forward header press station either the shaft 11 in one direction or by rolling to the transverse direction 18.

20

The paper roll may also enter the end-press station in transverse direction 18a and exit in the axial direction 11.
