Joint glue machine

Description

Joint glue machine The invention relates to a joint glue. Machine with opposing press beds, which from a number of adjacent and alternately moving back and forth rails are formed, which each other opposite press beds the material to be glued, z. B. veneer strips, grasp at the beginning of the forward movement and release at the end. The rails are preferably arranged such that a number of them move the material to be glued forward without interruption. The grout according to the invention thus has cooperating press beds, the rails of which are constant  Have conveyor speed and through a feed unit upstream of these press beds, the loading parts at least have a higher conveying speed than the rails of the press beds during part of the loading movement. This type is particularly recommended in cases where the material to be glued has to travel a long press path or if it already has existing transport devices are to be converted into grouting. The drawing shows two examples of embodiments of the subject matter of the invention. Fig. R is a section on the line 1-I in Fig. 2, showing a plan view of a first embodiment; Fig. 3 is a section along the line I. I 1-1I I in Fig. ¢, which is a plan view of a second embodiment. In both embodiments, the press beds and their drives are the same. The upper press bed consists of two groups of Rails z and 2 and the lower one from two groups of rails 3 and 4. The rails i .work with the rails 3 and the rails 2 with the rails 4 together. The rails i are on the box girders 5, the rails 3 on the box girders 6, the rails 2 on the box girders 7 and Rails 4 attached to the box girders 8. The pillars 9 of a carriage frame, not shown, engage in the box girders 5 and 6, to which the impellers are also attached. The columns i i of another car frame also engage in the box girders 7 and 8 which the wheels 12 are attached. Between the upper columns 9 and the box beams 5 are springs 13 and between the upper columns i i and Box girder 7 springs 14 are used, which strive to move the carrier 5 and 7 and with them the rails i and 2 upwards. Between the lower columns 9 and the box girders 6 are springs 15 and between the lower columns i i and the box girders 8 are springs 16 used, which strive to move the carriers 6 and 8 and with them the rails 3 and 4 down. The impellers io and 12 run in guides 17 of the machine frame. From the above it can be seen that the rails i and 3 with the carriers 5 and 6 and the wheels io a carriage A and the rails 2 and 4 with the carriers 7 and 8 and the wheels 12 form a nib B. These, vague A and B are in moved horizontally back and forth by the following drive device: On eyes 18 of the carriage A, rods 19 engage, which are operated by levers 2o are articulated. On the pivot pins connecting the rods 19 with the levers 20 i sit pushbutton rollers 22. These are by means of the Springs 23 pressed against the cams 24. At the eyes 25 of the car B attack the cranked rods 26 which are articulated to the levers 27. On the poles 26 with the pins 27 connecting the pivot pins 28 are seated roller 29. These are by means of the springs 30 against the cams 31 pressed. The cam discs 24 and 31 sit on a shaft 32 which is driven by a motor, not shown, via the chain wheel 33. On the box beams 5, 6, 7, 8 and against the springs 13, 14, 15, 16, the eccentrics 34, 35, 36,37. You cause them Vertical movement of the rails. The levers 39 sit on the eccentric pins 38 to drive them. The levers 39 belonging to the eccentrics 34 are by means of the rods 40, 4I with the rocking lever 142, the lifting parts 139 belonging to the eccentrics 35 by means of the rods 43, 44 with the rocking lever 45, the levers 39 belonging to the eccentrics 36 by means of the rods 46, 47 with the rocker arm 148 and the levers 39 of the eccentrics 37 by means of the rods 49, 50 connected to the lever lever51. The Schuringhebel42, 45, 48 and 51 carry stylus rollers 52, which are attached to the shafts 32 and 53 Cam discs 54 work together against which they are pressed by the springs 55. The shaft 53 is from the shaft 32 by means of Vertical shaft 56 and the bevel gears 57 driven. The shafts 32 and 53 and thus the cams - 4, 31 and 54 rotate counterclockwise. The disks 24 and 3 i rise clockwise from a to b with constant slope, d. H. the carriages A and B and thus the rails i, 2, 3, 4 move during their entire conveying movement (to the right in Fig. i and 3) at a constant speed. The cam discs 24 and 31 fall from b to a clockwise very quickly. That is, the backward movement of the carriages A and B and thus the rail (to the left in FIGS. I and 3) takes place very quickly. At the moment when the stylus rollers 22, 29 touch their cams 24, 31 at point a, or shortly after that moment the stylus rollers 52 are raised to the large radius of their cams 54, which causes the levers 39 and with them the associated eccentrics be pivoted that the opposite rails of the same car close and the to be transported and closed Take glue and take it with you. ZIf the button rollers 22, 29 touch their cams 24, 31 at point b, or shortly before, they attract attention the small radius of these disks, and the opposing rails of the same carriage move away under the influence of the Springs 13, 14, 15, 16 from each other. The cams are offset from each other so that always the rails of at least one car grasp the goods and forward move.  These press beds moving forward at a constant speed are now in the example according to FIGS. I and 2 Upstream insertion rollers 58 which grasp the material and feed it to the press beds and have a peripheral speed which is greater than the conveying speed of the press rails. It is thus these insertion rollers 58 that the newly introduced veneer strips through to the already bump the moving beds of moving veneer strips. The insertion rollers are grooved. In the grooves 59, the circular arc ends 6o come Connection strips 61 to lie, which engage between two adjacent rails of the beds. The rollers can by known means, e.g. B. Chain drives to be driven. 3 and 4, the press beds are exactly the same as in the first example and therefore also with the  referred to the same numbers. Here, too, the rails i, 2, 3, 4 move at a constant conveying speed. That these press beds  Upstream loading unit now no longer consists of insertion rollers, but also of j beds of back and forth rails  ia, 2a, 3a, 4a. The structure of these loading beds is the same as the structure of the press beds described above. Equivalent parts are therefore included  the same numbers as for the press beds, only that now an a is added to these numbers. The only difference is  that the on the Shaft cams 24a, 31a which are seated on the shaft 32a move the rails to 4a to the right at a speed which is greater than  that of the rails i to 4 in their rightward movement. So here it is the rails up to 4a that connect the newly introduced workpieces to those already in  knock the workpieces on the press beds. The rails of the press beds engage between the rails of the loading beds, and vice versa. Under certain circumstances, you can  Design cams 24a, 31a so that the rightward movement (Fig. 3) of the rails yes to 4a towards the end of the speed of the  right-hand rails slows down to 4. In this way, sliding between the workpieces and the left part of the rails i to 4 is the  Press bedg switched off. In this case, one will advantageously choose the eccentrics 34a to 37a so that the rails yes to 4a at the beginning of their  The right-hand movement immediately closes to the left (Fig. 3), while it only partially closes to the right and only fully later. From the moment  at the point where the loading rails of one of the wagons begin their forward movement until the moment when these rails are also attached to theirs  have closed completely on the right end, the rails of the other car advantageously also go to the right, but somewhat open. First  When the rails of one car are closed along their entire length, the rails of the other car open fully and continue  Left. It is understood that one as a drive means for the rails other than those shown here, for. B. those from the earlier applications of  Applicant, can use. Neither do the rails need to be arranged on trolleys in any case.
