Description

Device for application of wrapping sheets
This invention relates to a device at the application of wrapping sheets on bales. The device comprises an upper contact means and a bottom conveyor.
At the wrapping of bales, for example pulp bales, by means of two wrapping sheets, today pre-cut sheets or rolls are used, from which the sheets are cut in connection with the wrapping. One sheet is transported to a lower folding position in a lower sheet pocket, and the other sheet is transported to an upper folding position in an upper sheet pocket. The sheets are placed in such a manner, that at the transport of the pulp bale via a feed conveyor in between an upper contact means and a bottom conveyor the pulp bale gets into contact with the two sheets, of which one on the upper side and one on the lower side of the bale shall follow along with the bale in between the contact means and bottom conveyor.
The bale height, however, can vary. In order yet to be sure that also the upper wrapping sheet is clamped up, in this case between the bale and contact means, various auxiliary means are provided. One such auxiliary means is that the height of the bale is measured in connection with the transport in between the contact means and bottom conveyor, and that the valve of the measurement controls the distance between the contact means and bottom conveyor by adjusting the position of the contact means.
While the bale together with the applied wrapping sheets is located between the upper contact means and bottom conveyor, the wrapping sheet sides in parallel with the transport direction are folded inward to the bale, whereafter the bale via a discharge conveyor is transported to a folding machine.
The problems at the present state of art are that the upper and the lower wrapping sheet, when the folding is to commence, in certain cases can be displaced in relation to each other in the transport direction. The point where the bale height is measured, possibly is not representative of the entire bale. The bale can be slightly oblique or uneven. When the bale height is measured in a point where the height of the bale is slightly higher than the remaining bale, the contact means will be positioned to such a position that the upper wrapping sheet will not follow along with the bale before the measured point gets into contact with the upper wrapping sheet.
If one side of the bale is some millimeters lower than its other side, this will be sufficient that the upper wrapping sheet will not be clamped up satisfactorily between the contact means and bale. This can result in that the upper wrapping sheet does not follow along with the bale at its transport in between the contact means and bottom conveyor. The sheet can be turned in relation to the lower wrapping sheet or be displaced in relation to the lower wrapping sheet.
In the case when the upper wrapping sheet follows along with the bale in between the contact means and bottom conveyor, the problem with the displacement of the upper wrapping sheet in relation to the lower wrapping sheet still can arise later. This can take place, for example, when the wrapping sheets are folded inward to the bale. While the bale is located between the contact means and bottom conveyor, the wrapping sheet sides in parallel with the transport direction, namely, are folded inward to the bale by means of folding plates. If the frictional force between the folding plates and wrapping sheet exceeds the force between the wrapping sheet and bale, the wrapping sheet will not follow along with the bale as it should.
The displacement of the wrapping sheets can create problems in the subsequent folding machine.
The present invention offers a device, which solves the aforesaid problems.
The contact means according to the invention comprises a plurality of pressure means, which are individually movable in vertical direction. The pressure means permit movements in vertical direction with a certain resistance at upward movements. A pressure means suitably can be des gned as a spring-loaded wheel or a spring-loaded roll. The pressure means can move independently of each other in vertical direction, so that each pressure means can abut the bale even if the bale is oblique or uneven. It is thereby ensured that the upper wrapping sheet is pressed against the bale so that the sheet follows along with the bale at its transport between the contact means and bottom conveyor.
Another advantage of the invention is that the pressure means ensure that the force between the contact means and bale will not become too great even if the bale swells while it is located between the contact means and bottom conveyor.
The characterizing features of the invention are apparent from the attached claims.
A preferred embodiment of the invention is described in the following with reference to the accompanying drawings, where
Fig. 1 shows a sheet application device according to the invention,
Figs. 2 and 3 show two different variants of sheet stoppers, and
Fig. 4 shows a pressure means.
From a stack of pre-cut wrapping sheets one wrapping sheet is fed into a waiting position 1. A sheet stopper 2 is provided to ensure that the wrapping sheet is located correctly and does not bounce back outward a distance or bounces obliquely when it is being fed into waiting position 1. The sheet stopper 2 as shown in Fig. 2 is designed as a shock absorber, which damps the impact arising when the sheet meets the side in the waiting position 1 opposed to the direction from which the sheet is fed in. A lip 20 is articulated on a swinging link 21, for example a hinge, so that the lip 20 in resting position suspends downward from the hinge 21. The hinge 21 is arranged so that when the wrapping sheet meets the lip 20, the lip 20 swings away from the wrapping sheet and this dampens the impact which otherwise could have caused the sheet to bounce back. A spring 22 dampens the swinging motion of the lip. The lip 20 can swing back to its resting position, but not out in the waiting position 1 of the wrapping sheet.
A damper 26 dampens the return movement of the lip 20.
From the waiting position 1 the wrapping sheet is transported to a lower folding position 3 in a lower sheet pocket 4. A new wrapping sheet is fed to the waiting position 1. This sheet is then fed to an upper folding position 5 in an upper sheet pocket 6. As soon as a wrapping sheet has been transported from the waiting position 1 , the sheet is replaced by a new one.
The wrapping sheets are placed so that the upper sheet has a substantially free portion suspending downward from the upper sheet pocket 6, and the lower sheet has a substantially free portion standing up from the lower sheet pocket 4. The free portions of the sheets are arranged so that they partially overlap one another. A pulp bale 7 is transported by means of a feed conveyor 8 against the wrapping sheets. The lower sheet is clamped between a driving bottom conveyor 10 and bale 7. The upper sheet is clamped between the bale 7 and an upper contact means 9. The wrapping sheets thus follow along with the pulp bale 7, one on the upper side and one on the lower side thereof, in between the contact means 9 and bottom conveyor 10. Before the pulp bale 7 is transported in between the contact means 9 and bottom conveyor 10, its height is measured by a measuring means 27, suitably an ultrasonic sensor or an analogue transmitter.
The position of the contact means 9 in vertical direction in relation to the bottom conveyor 10 is adjusted on the basis of the measured height of the bale 7. The positioning of the contact means 9 is made by a positioning means 1 1, which can be, for example, a pneumatic alternatively hydraulic lifting means or a mechanical gear means driven by a motor. The contact means 9 comprises a plurality of pressure members 12, which are individually movable in vertical direction and arranged so that the contact means 9 permits against its lower side limited movements in vertical direction. Due to the fact that the pressure members 12 are movable independently of each other, the movement against the contact means 9 can be of different size in different portions. A certain resistance exists against movements upward from a lowest possible level for each pressure member 12. A force, thus, acts downward from each pressure member against in this case the pulp bale 7. The size of movements possible in vertical direction is decided by the design of the pressure members 12.
The contact means 9 at the embodiment shown comprises two rows, each with six pressure members 12. Every pressure member comprises a wheel 13 for abutment to the pulp bale 7. The movability in vertical direction is effected in that every wheel 13 is located on a wheel axle 14, which is connected to an arm 15, which is rotary about an arm axle 16. An arm support 17 is provided to prevent the arm 15 from falling down beneath a lowest permissible level, which at the embodiment shown is a horizontal position for the arm 15. Thereby a lowest possible level for the pressure members 12 is obtained and, thus, the contact means 9 can come into contact with the bale 7. In order to receive a contact force between the bale 7 and wheel 13, a spring 18 is provided against the arm 15, so that a certain resistance is obtained when the wheel 13 moves upward.
The contact means 9 described is dimensioned to manage about 10 cm great movements in vertical direction from its lowest level and upward.
At the positioning of the contact means 9 it is to be observed that the distance beween the contact means 9 and bottom conveyor 10 is such that the bale 7 surely get into contact with the wheels 13 when it is transported in between the contact means 9 and bottom conveyor 10. Thereby the upper wrapping sheet is clamped between the bale 7 and wheels 13. The wheels 13 are pressed by the bale 7 upward, and a contact force between the bale 7 and wheels 13 is achieved, so that the wrapping sheet follows along with the bale 7 when it is transported through the sheet application device.
While the bale 7 together with the applied wrapping sheets is located between the contact means 9 and bottom conveyor 10, the wrapping sheet sides in parallel with the transport direction are folded inward against the bale 7.
A discharge conveyor 19 transports the bale 7 from the sheet application device to a subsequent folding machine.
The contact means, of course, can be designed in many different ways. The contact means described in the example can e.g. comprise a greater or smaller number of pressure members, which can be distributed in a way other than in two rows.
Every pressure member can comprise more than one wheel.
Every pressure member can be arranged so that the wheel is suspended on a vertical spring-suspended arm.
The pressure members can also, for example, be designed as balls in a holder, where the holder is movably suspended in vertical direction and rests against a flexible material so that movability with resistance in vertical direction is obtained.
The force between a pressure member and the bale, of course, must not become so great that the bale gets stuck or is subjected to shearing when it is transported between the contact means and bottom conveyor. In the case when the pressure members have the appearance as in the example described, the spring, thus, must be adjusted to create the resistance desired.
A pressure member can also be formed so that its dead weight produces the desired force against the bale. In the case when the variation between the heights of various bales is smaller than what the pressure members permit in vertical direction, no positioning of the contact means is required. In a plant for baling pulp bales the variation between the heights of the bales usually is smaller than 5 cm. A contact means with pressure members formed so that they manage movements in vertical direction of up to about 10 cm (as in the example described), thus, is fully sufficient to ensure that the wrapping sheets follow along with the bale when it is transported between the contact means and bottom conveyor.
A contact means for use in a device for the application of wrapping sheets on pulp bales should comprise pressure members designed to manage movements in vertical direction of preferably up to 20 cm, but at least 10 cm, and in any case 5 cm.
At the embodiment shown, the bottom conveyor is driving. The sheet application device can be designed so that the bottom conveyor and/or contact means are driving.
The sheet stopper 2 can be formed in several different ways. It can, for example, when it acts as a shock absorber be formed so that the impacts are taken up by an elastic material, such as foamed plastic. The sheet stopper 2 can also be formed so that it prevents the wrapping sheet from bouncing back. An example of such a stopper is shown in Fig. 3. The wrapping sheet is introduced into the waiting position 1 through a barrier means, which in this case comprises a spring-loaded entrance. A catch spring 23 abuts a shoulder 24. The catch spring 23 and shoulder 24 are formed so that a converging space 25 is formed, which guides the wrapping sheet in between the catch spring 23 and shoulder 24 and furher into the waiting position 1. The force between the catch spring 23 and shoulder 24 must be adjusted so that the wrapping sheet does not get stuck. Facing the waiting position 1 , the catch spring 23 and shoulder 24 have substantially horizontal surfaces in order to prevent the wrapping sheet to be guided back outward between the catch spring 23 and shoulder 24.
The barrier means can, for example, also comprise a pivoted barrier. The invention, of course, is not restricted to the embodiment shown, but can be varied within the scope of the claims with reference to description and Figures.
