Abstract

To make welded joints in continuously moved package material, it is necessary to have appliances by which the welding tool, for example an ultrasonic device, is guided over a specific stage element parallel to and the same speed as the packaging material. Synchronism is achieved only incompletely with the conventional systems based, for example, on the principle of crank mechanisms in conjunction with non-uniformity drives. In the appliance according to the invention, in which the carrier plates (1,2) carrying the welding tool are respectively arranged below and above the web-like material, synchronism between these carrier plates and the said packaging material is achieved by fastening the carrier plates to crank arms mounted on the planet wheels of planetary gears designed specially for synchronous operation. In the embodiment, the fastening points of the crank arms are arranged outside the boundary lines of the planet wheels rotating respectively within sun wheels, and the planet wheels are driven in oscillation, to the effect that the otherwise elliptical spatial curve of the crank arms is straightened into the curve segments located on both sides of their long axes. A ... in relation to the continuously moved package material is thereby ... of a specific stage element ... Original abstract incomplete. <IMAGE>

Description

The invention relates to a device speaking the preamble of claim 1.

In the production of, for example, plastic, Paper bags and their combinations are usually from tubular or web-shaped material gone, which is wound on a roll and on which to produce individual plastic, paper sacks and their combinations a number of work plans corridors are to be performed. So this must be web-shaped Perforation or cutting material in individual sections, each to be assigned to a sack be divided, with the floor area of each Bags according to their geometry a number of folding,  Gluing or welding operations can be performed have to. To a in the manufacture of such bags To achieve the highest possible throughput is called web-shaped raw material during these operations continuously moving. The problem here is that for example for the introduction of weld seams in the web-like material takes a certain amount of time becomes during which the welding device becomes fast moved together with the material mentioned and must be handled. At the end of this time span must be determined by the welding device removed again from the sheet material, at least by the length of the path mentioned in the opposite direction to Moved the direction of conveyance of the material back to Be put into action.

DE-GM 36 01 019.0 is a device for one bring fold lines or welds in the floor area of folded bottom bags known in which the required Tool is held on support plates that are above and are arranged below the sheet material and on both sides in the crank arms of crank mechanisms are holding. Because of the crank guidance during one turn of the carrier plates along one closed curve, which is perpendicular to the plane of the sheet material extends. The crank mentioned gears in turn act with non-uniformity drove together, through which the support plates in the Movement phase in which the tool carried by them to act on the web-shaped material move at the same speed as the material. However, this approximation may be due to the circular Orbit of the crank arms is only imperfectly reached the.  

On the other hand, any relative movement between the web-shaped material and the on this during the tools to Un accuracies, for example in the area of the weld seam to lead.

It is the object of the invention to provide a device for to design the genre described at the outset in such a way that between the respective tool, or this supporting plates over a defined distance a synchronization with the web-like material as far as possible is achieved. The tool used here can be a be known ultrasonic welding device. It can also be perforating, cutting, or Act glueing tools. This task has been solved in a generic device by the features the labeling part of claim 1. As is known gives the curve of an ellipse as a special case one prolonged hypotrochoids or hypocycloids if the radii of the base circle and rolling circle are 2: 1 behavior. If you decrease the extent of the extension Hypocycloid, the ellipse goes in a straight line in the limit case about which, however, is not of interest here. These kinematic regularity is determined by a planetary simulated drives, in which in a sun gear Planet wheel rotates, the radius of which extends to the radius of the Sun gear behaves like 1: 2. Will the attachment points from the crank arms holding the support plates arranged half of the circumference of the planet gears, describe the end points of the crank arms in one revolution of the planet gear along the inner circumference of the sun rades the curve of an ellipse. Is used in the front lying case of the major axis of the ellipse ordered ellipse section, its geometric deviation from a straight line symmetrical on either side of the cut point with the small axis through oscillating drive  of the sun gear balanced in a certain area becomes. This results in a distorted one Ellipse, which has two sections that are not extend parallel to their major axis and which in the present case for synchronizing the support plates with regard to the movement of the web-shaped packaging materials are used, the latter between the Carrier plates is guided. That of the invention drive device associated with a uniform clock moderate output movement motor or a drives mechanical connection to the clock shaft of the device directly over the planetary cranks on the inside side of the sun gears revolving planet gears, where for, in a certain phase to the circulation of the Planetary gears an oscillating movement of the sun gears effecting drive a special motor may be provided can. The input wave of the Planetary gear can be understood, in the simplest case the planetary crank. It can be the oscillating motion the sun gears but also with the interposition of one corresponding gear directly from the uniform Rotational motion of the motor can be derived. Thereby, that according to the invention along a defined route element, the amount of which by the angle of rotation the sun gear is determined, a parallel guidance of the Support plates relative to the continuously moving web shaped material is given, along this Route element also a largely constant Ge is a synchronous drive system created by which relative movements between the Welding device and the web-shaped material during of the welding process are largely eliminated. This The advantage is not only with welding tools such as for example an ultrasonic welding device, son also with others, to influence the train  Shaped material reaching tools where Relative movements between the tool and the ge named material during the machining process must be prevented.

The features of claim 2 represent a particular advantageous embodiment of the invention direction. However, it is also possible to agree other arranged support plates on both sides of the same to be stored in crank arms.

The features of claim 3 bring the advantage yourself that from the uniform output movement of a Motors don't just drive the planet wheels is derived, but also the drive energy for the oscillating drive of the sun gear. The Cam gear or the cam gear is stationary here in a fixed phase relation to the angle of rotation of the Planetary gear, so that from the oscillating movement correction function derived from the sun gear at defined waypoints of the route element and always takes effect to a defined extent.

The features of claims 4 and 5 bring the advantage one that can be predetermined with simple means Phase relationship of the angles of rotation of two superimposed ordered sun gears with it. A fixed phase relationship the angle of rotation of both sun gears is necessary in order to correction function derived therefrom evenly those above and below the sheet material exercise moving support plates. It is natural too possible by arranging appropriate intermediate gears the uniform rotary motion of a single motor of all planet gears as well as the oscillating movement derive all sun gears.  

The features of claim 6 bring the advantage of clear positioning of the tools with it, whereby in the case of a welding device, for example one Ultrasonic welding device, from which the Necessary prestressing force is derived from the welding process, which in a direction perpendicular thereto from the Vibration movements of the respective ultrasonic sensor is superimposed. The constructive design of one Spring preload with associated receiving devices for the tools can basically be pre-selected be taken.

The features of claim 7 bring the advantage themselves that the device according to the invention on below different formats or directions of weld seams is easily adjustable.

The features of claim 8 are ver in storage relatively large support plates useful for reasons mechanical stability. The drive devices are naturally of such a nature that all Crank arms in a fixed phase relationship to each other be moved. The features of claim 9 bring the Advantage with it that the clock intervals and thus the Synchronous range of the device can be changed. The distance along the Plastic sack track are understood, at the beginning and endpoints each the beginning of the influence of the Tool takes place, which in the following time along a certain route element essentially speed bleaching is performed with the plastic bag conveyor. The dimensions of this track element are due to the geometric dimensions of the drive according to the invention facility provided. Under the term "synchronism area "is intended to be the proportion of the routes mentioned  element on the line corresponding to the pitch be understood. According to the invention, there is now Possibility of driving the planetary cranks direction to drive non-uniformly, causing the clock distances are changeable. While the speed of the support plates during the synchronization phase of the Ge speed of the plastic bag conveyor essentially ent speaks, takes place outside the synchronous phase - in the frame a complete circulation of the supporting plates Crank arms - a deceleration or acceleration of the Circulation of the crank arms instead, so that the result in changes in the time interval, during which the support plates along their ellipses similar crank after the end of the synchronization phase "led back" and again to influence art be brought to the bag.

The features of claim 10 provide a practical very advantageous, especially inexpensive bare and very flexible use embodiment. In principle, any electric motor can be used as the motor be set, its speed depending on the rotation angle is controllable and the corresponding control facility is assigned.

The features of claims 10 to 12 represent a variant of the irregularity drive, in which an un uniform movement by superimposing an equal shaped and a non-uniform, for example oscillating movement is generated. The oscillating Movement can, for example, by a speed controllable motor are generated, whose speed as Function of the angle of rotation is controllable. According to the Gear ratios of the planetary gear can here at one of the speed control of the speed controllable Motor corresponding output speed change set  will. Instead of this electrical speed change can also be a uniformly rotating one Engine in connection with a speed change acting intermediate gear can be provided, the latter designed, for example, as a cam gear is. Particularly advantageous, especially with regard to the flexibility of hiring a particular Un uniformity here is the arrangement of a step loose gear variation enabling gear.

1 and 2 are in Fig. 1, the bottom and top half of a plastic bag web 3 , or plastic-coated paper web or of tube sections made of plastic or several paper webs with embedded plastic layers, for example the so-called pinch tubes, - in the following only as Plastic sack conveyor called - arranged, to be described in relation to these movable support plates of the device according to the invention referred to, which extend parallel to the plastic sack conveyor.

There are the support plates 1, 2 - as can be seen in detail from FIG. 2 - each on two, horizontally and parallel to each other extending crank arms 4, 5 , which protrude laterally from the housing 6 of a drive device 7 to be described. The Antriebseinrich device 7 includes, in addition to a motor, a transmission to be written in more detail, through which the drive energy of the motor is transmitted to the two pairs of the crank arms 4, 5 arranged one above the other.

The plastic sack track 3 is either unwound as a tubular material from a roll, not shown, or is also passed in sections horizontally, ie in the direction of arrow 8, between the support plates 1, 2 .

The support plates 1, 2 are used in the embodiment shown, for example, for receiving and guiding two ultrasonic welding devices 9 arranged one behind the other in the direction of flow of the paper bag web. Each of the two ultrasonic welding devices 9 consists of a vibration generator 10 fastened to the upper support plate 1 and a sonotrode 11 and a reflector or anvil part 12 fastened to the lower support plate 2 . The mutually facing surfaces of sonotrode 11 and anvil part 12 are designed in a manner known per se such that a linear weld seam can be produced. This will be discussed in more detail below. The anvil part 12 and / or the sonotrode 11 are resiliently mounted and are pressed against each other in the direction of the arrows 13 under tension during the execution of the welding process. The structural design of the spring-loaded receptacle of these parts in the support plates 1, 2 can be designed in any way, so that a related graphic representation has been dispensed with.

The anvil part 12 and the sonotrode 11 of the two ultrasonic welding devices 9 are - as indicated in Fig. 2 by the arrows 14 - arranged about their longitudinal axes 15 so that the direction of the weld to be adjusted is also adjustable. There are two ultrasonic welding devices 9 in the other direction in the direction of arrows 16 slidably arranged in the support plates 1, 2 , the displacement for example via an elongated hole 17 he can follow, the lateral limits serve as a guide for the ultrasonic welding devices 9 . The con structive design of the displaceability of the ultrasonic welding devices 9 can, however, also be formed as desired. In practice, this setting described the availability of the ultrasonic welding devices 9 to adapt to different formats of the plastic bags to be produced, or paper bags with plastic inserts, both in terms of the dimensions and also visually the position and direction of the weld seams.

A plastic sack is shown in FIG. 3 only by way of example, the weld seams 18 of which each run at angles to the lateral boundaries.

In practical operation of the device, the plastic sack track 3 is continuously moved at a certain speed in the direction of arrow 8 . For the implementation of the welding process, a certain time interval is necessary so that over a minimum distance - seen in the direction of arrow 8 - the support plates 1, 2 with the ultrasonic welding devices 9 must be moved at the same speed parallel to the plastic bag path 3 . This synchronism between the ultrasonic welding devices 9 and the plastic bag web is achieved according to the invention over a certain distance by a special gear adapted to this purpose, to be described below, through which the uniform drive movement in an elliptical path of the support plates 1, 2 carrying crank arms 4, 5 is implemented.

With 19 in Fig. 1 elliptical space curves are referred to, which extend perpendicular to the plane of the plastic bag path 3 and each describe the circumferential path of a crank arm 4, 5 . Here, the curve section of the space curves 19 between the dash-dotted lines 20, 21 is used as the synchronous area, this synchronous area characterized by the arrows 22 essentially representing the track element which is available for the welding process during the passage of the plastic bag path 3 .

First of all the kinematic principle of the transmission of the invention is to be explained with reference to Fig. 4. Be known results in an elliptical shape curve as a special case of a hypotrochoid when the radius of the rolling circle rolling on the inside of a base circle corresponds to exactly half of the base circle. In Fig. 4, 23 is the base circle, 24 the rolling circle and 25 a point P , which lies on the extension of the diameter line 26 of the rolling circle 24 . Regarding the radii r, R of rolling circle 24 and base circle 23 , the relationship r = R / 2. If the rolling circle 24 starts from the starting position shown in the direction of arrow 27 on the inner circumference of the base circle 23 , the point P describes the elliptical space curve 28 , of which only half is shown for reasons of clarity in the drawing. The center point M of the rolling circle 24 moves here on the circular orbit 29th

If you interpret the system of basic circle 23 and rolling circle 24 as a planetary gear, with an internally toothed sun gear with an externally toothed planet gear in hand, the movement of point P can be technically simulated by a crank arm that is firmly connected to the planet gear. In order to compensate for the deviations still existing due to the elliptical shape with regard to a straight-line movement, he now moves according to the invention the base circle 23 corresponding to the sun gear about its axis of rotation 30 in accordance with the rotation of the rolling circle 24 or the planet gear, oscillating clockwise or counterclockwise so that the corrected one elliptical-like space curve 31 results, of which in turn only half is shown. In this way, the deviation of the movement path of the point P from a straight-line movement in the direction of the arrow 32 is corrected in a region which is delimited by the lines 20, 21 shown in broken lines. By appropriate choice of the rotational speed of the rolling circle 24 or the planet wheel corresponding to this there is thus the possibility of achieving a largely uniform speed in the direction of arrow 32 within the area between the lines 20, 21 . In theory, there would also be the possibility, by reducing the distance between the point P and the rotation axis 30 , of still stretching the shape of the elliptical space curve, so that it degenerates into a straight line in the limit case. However, since a minimum stroke in the vertical direction between the support plates 1, 2 is required, a minimum distance between the point P and the axis of rotation 30 of the sun gear cannot be exceeded. According to the invention, a planetary gear mechanism based on this mechanical principle is now used to design a synchronous drive, the movements of the crank arms 4, 5 being simulated according to the space curves of point P , in particular the corrected space curve 31 .

The structural design of the drive device 7 is explained below with reference to FIGS. 5 and 6, in which functional elements that correspond to those of FIGS. 1 to 4 are also numbered in accordance. Since - based on the drawing of FIG. 1, the drive systems of the left-hand crank arms 4 can be identical to those of the right-hand crank arms 5 , the following illustration can be limited to one of these drive systems.

Within the housing 6 , a motor 33 or a mechanical connection to the clock shaft of the Antriebseinrich device 7 is arranged, the output shaft 34 of the motor 33 via a gear branching stage 35 with the plane cranks 36, 37 of two planetary gears 38, 39 in connection. The transmission branching stage 35 is designed in such a way that the output speed of the motor 33 is transmitted uniformly to both planetary gear cranks 36, 37 .

The ends of the planet gear cranks 36, 37 each lead a planet gear 40, 41 , which is in each case with the internal toothing of a sun gear 42, 43 in engagement. Here, the radii of the sun gears 42, 43 to those of the planet gears 40, 41 are 2: 1.

The external toothings 44, 45 of the two sun gears 42, 43 are in engagement with one another. The planetary cranks 36, 37 are rotatably supported in the hollow sun gear shafts 46, 47 .

On the planetary crank 37 or the output shaft 34 , rotating with this, a cam 48 is arranged, which is equipped on the circumferential side with a positive guide 49 for the roller 50 of a roller lever 51 , which roller lever is fixedly attached to the sun gear shaft 46 . The structural design of the positive guide 49 can be of any desired design. It is used in conjunction with the roller lever 51 , as can be seen in particular in FIG. 5, only for the purpose of correspondingly, in accordance with the curve contour of the positive guide 49, the sun gear 42 and, due to its linkage with the sun gear 43 , this also in oscillating movements in opposite directions to the sun gear 42 offset, which are in a fixed phase relation to the angular position of the crank arms 4, 5 . Naturally, instead of the positive guide 49 and the roller lever 51 , a spring-loaded cam mechanism or a spring-loaded roller lever can also be provided, which rolls on the outer contour of the cam plate 48 .

The drive system which is different on the left or right in relation to FIG. 1 can be constructed identically to that described in FIGS. 6 and 7. However, it is also possible to distribute the output speed uniformly over a total of four planetary gear cranks 36, 73 - corresponding to the two drive systems - from a single motor via corresponding gear branching stages. However, the latter variant is not reproduced in the drawing.

It is the cam with respect to the profiling of its peripheral surface or the positive guide 49 be such that arms 4, 5 a largely uniform speed in the horizontal direction, that is parallel to the arrow 32 , which is achieved in the modification, over a certain angle of rotation of the crank the otherwise elliptical space curve, which falls out as a special hypotrochoid curve, is expressed in relation to the corrected space curve 31 . It is the angular range of the crank arms 4, 5 , over which a synchronism is achieved, in connection with the rotational speed of the crank arms 4, 5 and the throughput speed of the plastic bag path 3 such that a reliable weld seam formation is possible in the synchronous range.

During the passage of the plastic sack track 3 , the sonotrodes 11 and the anvil parts 12 associated therewith are moved towards one another in the synchronization area and are then horizontally in the mentioned synchronization area at the same speed as the plastic sack track 3 in the direction of arrow 8 ( FIG. 1). In this synchronous range, the sonotrodes 11 and the anvil parts 12 are under spring preload, the welding being achieved by superimposing oscillating movements which are triggered by the ultrasound transmitter or oscillation generator 10 . The welding process can thus be carried out with great reliability on a continuously moving plastic bag web. After completion of the welding process, the crank arms 4, 5 are removed due to the associated space curves 31 from the plastic bag track, are moved in the opposite direction to the arrow 8 and then again interact with the plastic bag track to create further welds.

Instead of the ultrasonic welding device 9 , other tools or tool systems can naturally also be attached to the support plates 1, 2 , which are used in the production of packaging materials and are used on continuously moving paper or plastic bag webs. These can be perfo or cutting devices, glue application devices and the like. In all of these cases, the tool system interacts with the plastic bag web in a certain time interval, the tool system being moved in the same way during this time interval, ie largely without any difference in speed to the plastic bag web.

The device described above is characterized by a drive device 7 , the essence of which is a special gearbox which produces a uniformly uniform speed over a limited range on the output side, the uniform rotational movement of the output shaft of a motor acting as the input variable of this gearbox. The cycle distances, namely the distances on the uniformly linearly moving plastic bag path 3 , at the respective start and end points of the welding, cutting, perforating or other tool for acting on the plastic bag path, lie in accordance with the dimensioning of the cranks of the gearbox described above.

In the following two variants of the above-mentioned device will be explained with reference to the illustrations of FIGS. 7 and 8, the pitch of which are variable.

In Fig. 7, 7 ' denotes a drive device, which corresponds in structure to that of FIGS. 1 to 6 substantially. It only contains no motor 33 and it is the planetary gear crank 37 ( Fig. 6) now set as an input shaft 37 'of the drive device. 4, 5 in turn designate the crank arms to which the support plates 1, 2 are attached in the manner described above.

The input shaft 37 ' is connected to the output shaft 52 of a superposition gear 53 in mechanical connection, which in turn two input shafts 54, 55 are assigned. While the input shaft 54 is used to transmit a uniform rotational movement, a transmission angle, dependent on the transmission characteristic of the superposition gear 53 , is transmitted via the input shaft 55 , dependent on the non-uniform rotational movement. The introduced via the input shafts 54, 55 , under different rotational movements are summarized in the overlay gear 53 , whereby on the output side, ie in the output shaft 52 a rotary movement is generated, the speed of which slows relative to a nominal speed over a definable angle of rotation and accelerates over the rest of the angle of rotation takes place, with the proviso that, based on a full revolution, the deviations in the angle of rotation compared to the rotational speed reached with the nominal speed are balanced. The reduced or increased speed in this sense compared to the nominal speed is selected in accordance with the transmission characteristic of the drive device 7 ' and the uniformly linear speed of the plastic bag conveyor 3 . The cycle distance is determined by this nominal speed.

The superposition gear 53 can be a planetary gear, for example, the input shaft 55 of which is connected to a speed-controllable motor, the speed of which can be controlled as a function of the angle of rotation. The non-uniform rotational movement of the input shaft 55 as a function of the angle of rotation can also be achieved via a cam mechanism, which in turn transmits a uniform rotary movement on the input side, with different control curves corresponding to the gradations of the angle of rotation, by means of which the output-side speed of the superposition gear 53 is to be reduced come individually to the intervention, must be provided.

In Fig. 8, the input shaft 37 'of the Antriebsein direction 7' is directly coupled to a motor 56 , the output shaft 57 is precisely controlled in the above sense with respect to a nominal speed. The motor 56 interacts with a control device, not shown in the drawing, which is freely programmable with regard to the assignment of the angle of rotation and speed, so that any speed-angle of rotation characteristics can be set in the simplest way.

If the speed of the output shafts 52, 57 is thus reduced in the synchronizing phase of the crank arms 4, 5 in the superposition gear 53 or the motor 56 , which is synonymous with another increase in this speed, the synchronous range, namely the distance between two successive works, can intervene , during which a synchronization of the support plates 1, 2 and the plastic bag conveyor 3 takes place, and vice versa.
