Definitions
- the present invention relates to a method for covering boxes according to the preamble of claim 1 and a device according to the preamble of claim 8 for carrying out the method.
- Document US2009 / 0156380A1 shows a system for the production of boxes with a device for obtaining the raw boxes.
- the raw boxes and the reference material provided with adhesive the blank blanks are fed to a joining device by transport devices from the respective upstream devices. This places the raw box with its bottom on the glued side of the blank.
- the blank is rolled onto all four box walls. Any overhang of the blank is folded inwards.
- a drawing device is assigned to each wall.
- the four retrieval devices are arranged opposite one another in pairs. They each have a drive roller and a slider. The panels are joined to the outer walls by rolling the grinding rollers on the outer sides of the box.
- the box is passed vertically between the stationary first pair of referring devices.
- the box then remains in a rest position and the tuck-in slides of the first pair hit the overhangs of the blank inwards.
- the second pair of pulling devices then rolls the product onto the remaining walls in a vertical movement of its drive rollers, before their push-in slides knock in the remaining protrusions.
- a form stamp is lowered into the related
- Such a reference device allows a compact design.
- the disadvantage is the poor accessibility of the components as a result. especially the It is more difficult to clean the elements that come into contact with the reference sheet.
- the arrangement of the extraction devices to one another means that only one couple can process the box at a time. The other pair must wait until this processing has been completed or the box has been transported out of the device. The performance of the system must therefore remain limited.
- the forming die In order to securely glue the impacts of the panel on the one hand to the inner surfaces of the raw box and on the other hand to avoid damage to the box, the forming die must be manufactured to be extremely dimensionally accurate. This requires a separate molding die for each internal dimension of a box to be manufactured. Format deviations in the raw boxes, for example due to manufacturing tolerances or climatic influences, lead to a corresponding loss of quality in the finished box and even to scrap.
- the invention achieves the object by a method with the features of patent claim 1 and by a device with the features of patent claim 8.
- Advantageous further developments of the invention are characterized by the features specified in the subclaims.
- the box lamination machine comprises various processing devices and transport devices. These processing devices are arranged on the transport paths of the transport devices.
- the respective box blank to be obtained is brought one after the other to different processing stations of the box laminating machine for processing by a transport system.
- the box blank to be obtained is transported in a plane parallel to the bottom of the box blank.
- the laminating machine comprises at least one transport device and two side rolling devices.
- the side rolling device is arranged on the transport path of the transport device. It has at least one driver and a counter holder assigned to this driver.
- the counter holder is immersed in the raw box.
- the scraper rubs the corresponding wall area of the blank on the assigned wall of the raw box against the counter holder.
- the device has a first guide system of the grinder, which defines the trajectory of the grinder.
- a second guide system of the counter holder defines the movement path of the counter holder.
- This movement path of the counter holder comprises at least one section which is oriented parallel to the transport path of the raw box. The rubbing during the continuous transport of the box allows a temporal overlap of movements, so that an increased throughput is possible.
- the two opposing side rolling devices act one after the other on the same box blank in order to rub one area of the panel in each case.
- an optimal flow of forces can be achieved through the panel and the wall. Likewise, losses in quality or even damage to the boxes resulting from format deviations in the individual box blanks are avoided.
- the counter holder is mounted pivotably about an axis. This pivot axis runs parallel to the respective wall to be covered. It lies above the boxes in such a way that the movement of the counter holder in the area of the box wall runs approximately transversely to the transport direction of the boxes.
- the rubbing device comprises a linear guide transverse to the transport direction in which the counter-holder is guided.
- Another alternative embodiment provides a pivot axis for the grinder. This runs parallel to the wall to be covered.
- the pivot axis is spaced from the contact surface of the scraper in such a way that this contact surface experiences a significant proportion of movement perpendicular to the wall to be covered.
- the grinder is received in a linear guide of the grating device. This linear guide is oriented perpendicular to the box wall to be covered.
- This transverse movement is preferably generated by a controllable drive.
- This controllable drive exchanges signals with the control of the box laminating machine. In this way, the transverse movement can be optimized for the materials used and the current machine speed.
- the device preferably has fixed end positions with respect to the movement perpendicular to the wall to be covered. In this way, the movement of the rubbing device or the counter-holder can be reproduced, and consistent quality can be ensured.
- a mechanical stop is particularly suitable for this purpose, which prevents leaving the permissible range regardless of possible malfunctions in the control system. Rubbing is particularly advantageous when the transport movement is ongoing.
- the counter holder moves in the transport direction synchronously with the respective box as long as it is inside the box.
- the receptacle of the counter holder has a guide running in the direction of transport and a corresponding drive. Rubbing devices opposite one another with respect to the transport path are also arranged one behind the other in the transport direction.
- the counterholder preferably experiences a circumferential movement with a pronounced linear movement section which runs parallel to the transport direction. During the rubbing, the respective wall to be covered experiences a relative movement relative to the components of the device that are in contact with it.
- FIG. 1 shows a schematic representation of the product flow and the associated transport devices of a device for referring to boxes
- FIG. 2 shows a schematic representation of a side rolling device; 3 counter holder of a side rolling device; FIG. 4 a movement diagram of a side rolling device; FIG. Fig. 5 scraper of a side rolling device.
- Fig. 1 the product flow when drawing boxes is shown schematically.
- the raw boxes 2 are each made available by a feeder 7 in a ready position.
- the box feed 7 has a transport device with first transport belts 31.
- the raw boxes 2 are brought into the readiness position with their bottom 21 pointing downwards and oriented horizontally.
- the end walls 22 of the raw box 2 are oriented parallel to the feed direction, while the side walls 23 are oriented transversely to the feed direction.
- the feed direction is transverse to the Transport track 1000 on which the processing devices 100, 200 are arranged.
- the readiness position of the raw boxes 2 is arranged adjacent to a conveyor belt 30 of the sheet feeder 8 that supplies the sheet blanks 1.
- the panel blanks 1 are individually glued and taken over by the conveyor belt 30 and moved along a linear conveyor track 1000. Suitable devices for applying adhesive to the panel 1 are well known, are not shown in the figures and are not explained further.
- a robot also not shown, takes over the provided raw box 2 and places it in a curved placement movement 1010 precisely on the bottom area 11 of the reference product 1.
- the unit 3 now connected from the raw box 2 with the blank 1 glued to its bottom 21 is attached to a Conveyor belt 30 transferred subsequent conveyor 9 with the same transport direction 1000.
- the transport belts 32 of this conveying device 9 transport the box units 3 through the processing devices 100, 200 arranged along the transport path 1000 to completely cover the box units 3.
- the elements 101, 102, 103, 105 of a left-hand side roll-up device 100 and one opposite one of these interacting with the box unit 3 and right-hand side roll-on device 200 arranged downstream are shown in FIG. 2.
- the side rolling devices 100, 200 are constructed in a mirror-inverted manner with regard to the transport path. In the following, therefore, only the left-hand side roll-on device 100 will be explained.
- a first pressure roller 105 of the left-hand side roller device 100 is shown in its starting position below the path of movement of the box units 3.
- the grinder roller 105 is substantially cylindrical. Its axis of rotation runs parallel to the transport direction 1000 of the box units 3. Coming from its starting position, the grinder roller 105 rolls in a vertical movement part 1004 on the side wall 23 and thereby rolls the assigned outer area 13 of the blank 1 on the side wall 23.
- a counter holder 101 is provided in order to support the side wall 23 when it is rolled against the grinder roller 105.
- This counter holder 101 is formed by a pair of punches 102, 103.
- a support plate 104 is attached between the punches 102, 103 for full-surface support. Together, a pair of dies 102, 103 with the associated support plate 104 form a support surface 115, shown in FIG. 3, which is parallel to the associated box wall 23.
- a circumferential movement 1005 of the counter holder 101 is made possible by the linear guide systems 109, 111 shown in FIG. 3.
- a horizontally oriented linear guide 111 is arranged parallel to the transport path 1000 of the box units 3. It accommodates a vertically aligned linear guide 109 in the manner of a coordinate table.
- the punches 102, 103 of the counter holder 101 are received in the vertical linear guide 109.
- the vertical guide 109 is connected to a drive 112 in such a way that it can be moved along the horizontal guide 111.
- the vertical movement portion 1002 of the counter-holder 101 is generated by a further drive 110 acting on the punches 102, 103.
- This drive 110 for the vertical movement portion 1002 of the counter-holder 101 comprises a motor-driven, vertically movable guide track 114. This runs parallel to the transport direction 1000 of the box units 3 In the guide track 114, a roller 113 attached to a punch 103 of the counterholder runs in order to transfer its vertical movement 1002 to the counterholder 101.
- the counter holder 101 While the box 3 is continuously transported in the predetermined direction 1000 by the belt 32, the counter holder 101, coming from its starting position 1100 above the box unit 3, plunges into the raw box 1 during a closed circulating movement 1005 on the side wall 23.
- the rotational movement 1005 of the counter holder 101 takes place essentially in a plane parallel to its support surface 115. In FIG. 2, this is spanned by the transport path 1000 of the box units 3, which runs in a horizontal x-direction, and a vertical y-direction.
- the orbital movement 1005 is composed of several sections.
- the sinking 1006 into the box 3 begins in the starting position 1100 above the box unit 3 and ends within the box unit 3 at or something above to its bottom 21.
- the sinking 1006 is described by a vertical downward movement relative to the box.
- the countersinking 1006 is followed by a holding section 1007, during which the counter holder 101 maintains a fixed position relative to the box unit 3.
- the counterholder 101 moves synchronously with the box unit 3 in its transport direction 1000.
- the actual rubbing of an outer area 13 of the blank 1 against the outer surface of the associated box wall 23 takes place by the pressure roller 105.
- the subsequent lifting 1007 corresponds to the sinking 1006 with reversed vertical movement component 1002.
- the counter holder 101 returns to its starting position 1100 in a horizontal return movement 1009.
- FIG. 2 shows the pivot axis 1200 of the counter holder 101.
- the punches 102, 103 with the associated support plate 104 are rotatably mounted about this.
- the pivoting 1011a is carried out by pneumatic cylinders 116, which are controlled by the box lamination machine.
- the circumferential movement 1013 of the grinder 105 is described in a simplified manner by three successive linear movement segments.
- the actual rubbing movement 1014 can be subdivided into a portion parallel to the transport direction 1000 and a vertical portion 1004.
- FIG. 5 shows the structure of a grinder, which additionally carries out a linear movement 1011b transversely to the transport direction 1000 of the boxes 3.
- the grinder roller 105 is accommodated in a cross table analogous to the counter holder 101.
- This comprises a vertically running linear guide 17, the carriage of which carries a horizontal linear guide 122 which runs perpendicular to the transport direction 1000.
- a pneumatic cylinder 121 is provided for the infeed 1011b transversely to the transport direction 1000.
- the drive 118 of the vertical movement 1004 is generated by means of an electric motor with a rotating toothed belt 119.
- the receptacle has a roller 124 which rolls on a curve 123 which runs essentially vertically and serves as a stop.
- FIG. 4 shows a movement diagram. All movements 1000, 1001, 1002, 1004, 1011a, 1011b are shown in simplified form composed of linear components of different gradients.
- the transport movement 1000 of the box units 3 is shown in dotted lines. It runs as a rising straight line in the x direction over time t.
- the horizontal movement 1001 of the counter-holder 101 shown in dashed lines is divided into the folding section 1007 and the return movement 1009.
- the vertical movement component 1002 of the counter bracket 101 is shown with a solid line. From FIG. 4 it becomes clear that the section of the horizontal movement 1001 synchronous with the transport movement 1000 includes the movement sections sinking 1006, folding 1007 and digging 1008 in terms of time.
- the vertical movement component 1004 of the drive roller 105 is also shown with a solid line.
- the drive takes place during the upward movement. This coincides in time with the folding section 1007 of the counter holder 101.
- the horizontal movement portion of the pressure roller 105 ensures a rolling movement on the box unit 3 only perpendicular to the bottom 21. One Relative movement of the pressure roller 105 to the box 3 parallel to the transport movement 1000 is prevented.
- the movement 1011a of the counter holder 101 perpendicular to the wall 23 to be covered and the alternative movement 1011b of the pressure roller 105 perpendicular to the wall 23 to be covered are shown in a common curve. It has a detent 1003 during the actual rubbing 1004.
- the horizontal movement portion of the drive roller 105 in the transport direction 1000 is not shown. It is in a simple manner identical to the horizontal movement component 1001 of the counter holder.
- the movement diagram from FIG. 4 shows the movement sequences in a schematically simplified manner. Instead of the incline jumps, curved transitions can be chosen.
- the machine dynamics can be favorably influenced in this way.
- the movement segments and movement components shown can shift or overlap with one another. In this way, the loads caused by the machine dynamics can be further reduced and process times improved.
- the transverse movement 1011a, 1011b of the counter holder 101 and / or the rubbing device 105 can also take place when the box 3 to be obtained is at a standstill. It is then possible to dispense with the movement components 1001 of the counter holder 101 or of the rubbing device 105 that are parallel to the transport direction 1000.
- the structure is simplified, but is not shown in the figures.
