Definitions

  • the invention relates to a profile grinding machine for woodworking, with which profile strips and similar workpieces can be produced continuously.
  • the raw profile which is created by means of a milling machine, is refined in the surface by means of the profile grinding machine, so that it can subsequently be stained, primed or painted.
  • a correspondingly profiled grinding block which oscillates back and forth linearly, i.e. in the direction of the profile extension, or a rotating, appropriately profiled grinding wheel is used, along which the profile to be machined moves past.
  • the processed surface must also be processed using hard brushes, e.g. made of plastic, in order to e.g. to remove the soft wood parts from the sanded surface, which emphasizes the wood structure.
  • Rotating brushes are generally used for this, but linearly oscillating brush bodies would also be possible in this case.
  • Known profile grinding machines generally work in such a way that the profile strip to be machined is placed on rollers and transported on by these rollers, while the upper side of the profile strip to be processed is processed by a grinding block or a grinding wheel or another processing unit from above.
  • the invention relates to a machine for grinding linear profiles if they consist of softer materials such as plastic or wood etc.
  • a machine for grinding linear profiles if they consist of softer materials such as plastic or wood etc.
  • profiled floor baseboards, picture frame profiles and the like are finely sanded on the surface after the rough shaping was carried out by previous milling.
  • a sanding block the profile shape of which is matched to that of the workpiece to be sanded, i.e. the profile strip etc., and the sanding block oscillates back and forth in the longitudinal direction of the profile over a relatively short distance, while the workpiece is permanently moved by means of a transport device and is transported relatively slowly in one direction.
  • the workpiece must be firmly gripped by the transport device in order to prevent it from slipping, which leads to excessive material consumption at this point due to the stoppage of the workpiece.
  • the sanding block must also be pressed against the workpiece with sufficient and continuously adjustable pressure in order to achieve the desired degree of material removal and thus surface quality.
  • the workpiece to be machined has been placed with the surface to be ground down in the transport device for this purpose, and the grinding block or blocks also acted on the workpiece from below.
  • the holder has two adjacent, mutually perpendicular surfaces against which corresponding surfaces of the processing unit are directed. Of these contact surfaces of the holder, one lies essentially vertically and the other essentially horizontally, and both run transversely to the direction of passage of the profiled strip to be machined.
  • the processing unit also rests on the horizontal contact surface of the holder, the processing unit is also at the correct height above the profile strip, so that the correct amount is obtained material is removed or the brushes rub the wood to the desired depth.
  • Such an exact assignment of the contact surfaces of the holder to the corresponding counter surfaces of the processing unit is possible in that at least one threaded bolt and at least two centering devices are located on the horizontal contact surface of the holder.
  • the two centering devices prevent angular misalignment of the processing unit to the direction in which the profile rail runs.
  • the threaded bolts can be inserted through corresponding bores in the processing unit attached and tightened with a nut, whereby the processing unit is pressed against the holder from above. This assumes the desired altitude, but under certain circumstances an overdetermination can be given by creating two flat surfaces against each other. This is prevented by the fact that the processing unit is not seated on the entire surface of the holder, but on raised areas with a small surface area.
  • the centering device and the reduced contact surfaces are standardized in one object in that the threaded bolts have a conically widened, rotationally symmetrical base, against which the through holes of the processing unit which are correspondingly enlarged on the underside are pressed by means of the screwed-on nut. Due to the rotational symmetry, there is an automatic centering and with appropriate selection of the dimensions of the base of the threaded bolt on the one hand and the counter surface in the processing unit on the other, only the conical surfaces rest on one another, but not the entire horizontal contact surface of the holder on the corresponding counter surface of the processing unit.
  • a threaded pin protrudes from this vertical surface of the holder, which has a widened, rotationally symmetrical end with a trapezoidal cross-section, so that this threaded pin approximately has the shape of a Countersunk head screw. This threaded pin is partially screwed into a through hole in the holder.
  • the processing unit has a slot in the vertical contact surface facing the holder, which is open at the bottom, so that the processing unit can be pushed down along the holder from above, whereby the threaded pin slides with its widened head into the correspondingly shaped slot.
  • This slot is widened in the form of a dovetail at its base, so that the threaded pin cannot be pulled out of this slot to the front, that is to say in the longitudinal direction of the threaded pin.
  • the slot also has a semicircular end, so that when this end is in contact with the head of the threaded pin, a semicircular, conical surface is created.
  • the threaded pin described at its non-widened end which comes to rest in the threaded hole of the holder, has a transverse slot for inserting a screwdriver or an equivalent shape, and this threaded hole is also accessible on the profile grinding machine, the threaded pin can also be accessed from this rear side are still screwed when the processing unit is inserted, in order to enable increased or reduced contact pressure on the processing unit against the vertical contact surface of the holder.
  • the adjustment of the threaded pin is only necessary if the parts lying against one another are worn or if the threaded pin is inadvertently adjusted.
  • This configuration of the processing unit and holder means that only the pressing nuts of the threaded bolts arranged on the top have to be loosened, whereupon the processing unit can be lifted up from the holder and a new one is inserted. Since this can be done in a few simple steps and no additional electrical plug connection has to be made, changeover times of less than one minute for the use of the next processing unit are the rule.
  • threaded pins and threaded bolts are preferably made of a material that is softer than the material of the opposing surfaces of the processing unit, that is to say, for example, of a brass alloy.
  • the advantage of the design of the linear grinding unit according to the invention is that the grinding block or blocks act on the workpiece from above. This enables the operator to control the work result optically and manually at any time.
  • the transport device consists in a manner known per se from a rotating conveyor belt against which the workpiece is pressed from above by pressure rollers.
  • pressure roller units that is to say carriers with at least one pressure roller in each case, in the front and rear region of the transport device, so that the grinding unit can act on the workpiece in the central region.
  • the grinding blocks are supported against the grinding unit by at least one resilient element.
  • This can be a spiral spring, for example.
  • These resilient elements not only ensure that the sanding blocks are pressed evenly against the workpiece, but also that the resilient element can be pretensioned by means of the stepless adjustment of the sanding unit towards and away from the workpiece, thereby varying the contact pressure when sanding .
  • the adjustment of the grinding unit to the workpiece takes place with the aid of a threaded spindle, on which there is a hand edge for adjustment, and by means of which a conventional spindle nut is displaced along the longitudinal direction of the spindle.
  • This adjustment is preferably used as a fine adjustment, while a rough adjustment is a displacement of the grinding unit relative to the tool holder in larger steps, for example screwing in predetermined holes.
  • two guide rods run at an approximately right angle skew to the longitudinal direction of the workpiece.
  • the tool carrier is not moved directly on these guide rods, which are firmly connected to the bed of the grinding machine. Rather, a slide is moved along these guide rods and fixed in the desired position, a bearing part being mounted on this slide by means of a bolt, the bolt extending parallel to the longitudinal direction of the profile.
  • the entire tool carrier can be pivoted relative to the slide about an axis parallel to the profile direction, depending on the optimal pressing direction of the grinding block against the workpiece, which does not always have to be the vertical.
  • profile strips with an approximately triangular cross-section are produced, in which the diagonal is to be profiled, then this profile strip rests with one smooth side on the conveyor belt and is pressed with the other smooth side against a stop arranged at right angles to the belt.
  • the ideal pressing direction of the grinding block is the diagonal between these two surfaces, i.e. an angle of approximately 45 degrees.
  • the optimum angle can be set and determined by clamping the bolt connection.
  • a graduation on the clamping device is advantageous for this purpose.
  • the grinding unit itself consists of a housing in which two grinding block holders are guided along linear guides, which run parallel to the profile direction and have a non-circular cross-section, so that pivoting out of the holder around the linear guides is not possible. Both grinding block holders are preferably guided on one and the same linear guide, the drive motor being located between the two grinding block holders on the top of the housing.
  • a connecting rod is eccentrically mounted on its output shaft for each grinding block holder, the eccentricity of which causes the oscillating linear movement of the grinding block holder.
  • the motor is preferably an electric motor, so that the profile grinding machine according to the invention manages completely without hydraulic supply.
  • the sanding block is not directly attached to the sanding block holder, but a sleeve protrudes downward from this sanding block holder, which sleeve extends outward through the housing of the sanding unit and with the Grinding block holder is firmly connected.
  • An extension of the grinding block base plate protrudes into the lower free end face of the sleeve, onto which the grinding block is directly attached.
  • At least one resilient element which generates the contact pressure of the grinding block against the workpiece, is located inside the sleeve between the grinding block holder and the extension of the grinding block base plate.
  • the resilient elements are compressed more and the grinding blocks are pressed more strongly against the workpiece due to the increased pretension, which increases the material removal.
  • the resilient element is preferably at least one spiral spring.
  • Such a purely mechanical solution to the contact pressure is not only simple and inexpensive to manufacture, but also easy to repair.
  • the pretension and thus the contact pressure can be increased or decreased, and a progressive or degressive change in the grinding pressure during delivery can be achieved by using several spiral springs arranged one inside the other.
  • a different contact pressure of the two grinding blocks can be achieved.
  • the machine frame 15 can be seen in which the transport path 18, consisting of a plurality of rollers 16, is mounted for the profile strips 17, of which at least one, but preferably several are driven, in order to further transport the strips under the Ensure processing unit 1 at the desired speed. It can also be seen the bracket 2 firmly connected to the frame 15, on the the respective processing unit 1 is hooked in, in order to then be connected to the power supply and the control unit of the machine via an electrical line 20 by means of plug connection 21.
  • Fig. 2 now shows a vertical side view of the holder 2, the later arrangement of the processing unit 1 is indicated by dashed lines.
  • the processing unit 1 faces a vertical surface 10 and a horizontal surface 11, which are adjacent and lie transversely to the direction of the profile strips.
  • the horizontal surface 11 is located on the top of the holder 2 and carries two threaded bolts 8, which are screwed into the holder 2, and have a rotationally symmetrical, conical foot 3, which sits with its broad side on the surface 11 of the holder 2.
  • the two threaded bolts 8 are arranged at the same distance from the vertical contact surface 10 of the holder 2, as the top view of the holder 2 according to FIG. 3 shows.
  • the widening 14 at the lower end of the threaded bore 13 is, however, dimensioned such that the machining unit 1 cannot come to a complete contact on the horizontal surface 11 of the holder 2, even if the widening 14 is pressed against the threaded bolts 8 by means of nuts the conical foot 3 of the threaded bolt 8 will be made.
  • the threaded bolt 8 together with the base 3 is made of a softer material than the counter surfaces of the processing unit 1, in this case brass.
  • the rotationally symmetrical, trapezoidally widened head of the threaded pin 4 can be seen, which is partially screwed into a continuous threaded bore 7, which passes through the holder 2 horizontally and also opens into the vertical contact surface 10 of the holder.
  • This threaded pin 4 has at its narrow rear end a transverse slot 6 for inserting a screwdriver, and this rear end of the threaded bore 7 of the holder 2 is also accessible at all times.
  • a slot 5 is incorporated into the vertical surface of the working unit 1 facing the holder 2, which is in the underside of the Working unit 1 opens and ends semicircular at such a height that this end abuts the holder 2 on the frustoconical head of the threaded pin 4 when the processing unit 1 is placed on it.
  • this slot is widened in the shape of a dovetail with a trapezoidal cross section, which has the same angles as the trapezoidal cross section of the threaded pin 4, but has a greater distance between the parallel cross-sectional areas. This has the effect that the end face of the threaded pin 4 facing the machining unit 1 does not abut the base surface 12 of the groove 5 when the machining unit 1 is placed on it.
  • the semicircular end of the slot 5, which can be seen particularly in Fig. 5, causes that by resting this semicircular end over about 180 ° of the outer surface of the head of the threaded pin 4 always the same height of the processing unit 1 is assumed above the profile bar.
  • the slot it is also easily possible to make the slot longer, so that the height is determined solely by the installation of the processing unit 1 on the frustoconical base 3 of the threaded bolt 8 on the top of the holder 2, and the threaded pin 4 in the slot 5 below whose semicircular end sits and only ensures that the vertical surface 10 of the holder 2 is as free from play as possible on the corresponding counter surface of the processing unit 1, because a small angle between these two surfaces would cause an incorrect height adjustment when using a grinding wheel and when using a grinding block, the only the end of the grinding block facing the holder 2 has a strong grinding effect, while the other areas have only poor contact with the surface of the eyelet, as a result of which the machining result would be greatly reduced.
  • FIG. 6 shows a side view of the transport device 3, in which a conveyor belt 18 runs over two deflection rollers 29 and a plurality of support rollers 30 located in between.
  • the workpiece 17 rests on the upper run and is transported further by the forward movement of the conveyor belt 18. In order to ensure sufficient pressure between the workpiece and the conveyor belt 18, the workpiece 17 is pressed against the conveyor belt 18 from above by the pressure rollers 31 of two pressure roller units 16.
  • These pressure roller units 19 are located in the front and rear area of the transport device 3, so that there is sufficient space in the central area for the grinding blocks 105 to act on the workpiece 17 from above.
  • the grinding blocks 105 are fastened to a grinding unit 104 which is supported by two guide rods 26 which run transversely above the workpiece 17, as also shown in FIG. 7.
  • a slide 24 is displaced along the guide rods 26 running transversely to the profile direction 25 by means of a spindle 32 in order to bring the grinding unit 104 into the correct position above the workpiece 17.
  • a bearing part 34 is pivotally fastened by means of a bolt 23 running parallel to the profile direction 25, to which the entire tool carrier 108 for receiving the grinding unit 104 is fastened.
  • the bearing part 34 On the side facing the tool carrier 108, the bearing part 34 has an approximately vertical dovetail guide, in which a correspondingly extending counterpart of the tool carrier 108 engages. Furthermore, a threaded spindle 120 is mounted on the bearing part 34 parallel to the dovetail guide 35, by the rotation of which the tool carrier 108 is displaced via the spindle nut 121 along the dovetail guide, that is to say with respect to the height of the workpiece 17. For this purpose, a handwheel 22 is attached to the upper end face of the threaded spindle 120, which serves to feed the grinding unit 104.
  • the grinding unit 4 can be adjusted by moving the slide 24 above and across the workpiece 17 possible in the direction of arrow 26.
  • the grinding unit 4 can be pivoted about an axis parallel to the profile direction 25 in accordance with the arrow 37 in FIG.
  • the height adjustment of the grinding unit 104 with respect to the workpiece 17 in accordance with the arrow 28 in FIG. 7 is possible by turning the handwheel 22, the self-locking design of the threaded spindle 120 and the spindle nut 121 preventing an automatic height adjustment.
  • Arrow 39 in FIG. 7 shows the adjustment of the pressure roller unit 19 along a guide rod 47 also transversely to the profile direction 25, that is to say parallel to the guide rods 26 of the grinding unit 104, in order to allow the pressure rollers 16 to act at the desired locations on the top of the workpiece 17, which is not shown in Figure 7.
  • the housing 27 of the grinding unit 104 is located on the tool carrier 108 and contains mainly the drive necessary for the linear oscillation of the grinding blocks 105: Within this housing 27, two grinding block holders 109 are guided on a linear guide 110, which runs parallel above the workpiece 17.
  • an electric motor 113 is arranged above the housing 27, on the output shaft 112 of which projects into the housing, two connecting rods 111 are eccentrically mounted, each of which drives one of the grinding block holders 109. Due to their linear guidance, this leads to an oscillation of twice the eccentricity of the connecting rod bearing 111 on the output shaft 112, so in the present case to a stroke of about 5 mm.
  • a sleeve 114 protrudes downward from the grinding block holders 109, which sleeve is firmly connected to the grinding block holder 109.
  • An extension 115 of the grinding block base plate 116 projects into the downwardly open free end of the sleeve 114, the maximum distance of the extension 115 from the grinding block holder 109 being limited by a stop 117 in the sleeve 114.
  • a compression spring 119 is arranged between the grinding block holder 109 and the extension 115, which exerts the necessary contact pressure on the grinding block base plate 116 and thus the grinding block 105.
  • the grinding block 105 is fixedly mounted on the underside of the grinding block base plate 116 and received in a form-fitting manner in a circumferential sleeve 41.
  • the grinding unit 4 and thus also the grinding blocks 105 are adjusted downwards by means of the handwheel 22 until they rest on the workpiece 17 and beyond, the grinding blocks 105 press against the workpiece 17 with increasing force during the oscillating grinding process, since in which the helical springs 119 are compressed by the adjustment by means of the handwheel 22, the preload of which increases, which essentially corresponds to the applied grinding pressure.
  • the profile grinding machine according to the invention can thus be set precisely and reproducibly in all respects by simple mechanical-manual adjustments without the need for additional hydraulic equipment.
  • the machining result visible on the top of the workpiece 17 and the machine can be checked during the machining process can be adjusted accordingly by increasing the contact pressure, changing the inclined position, etc.
  • the entire drive mechanism of the grinding unit 104 including the device for applying the contact pressure, is simple and easy to maintain and repair.
  • the contact pressure changes not only as a function of the adjustment of the handwheel, but also as a function of the spring characteristic of the spring 119. If this spring characteristic is designed to be flat, a very precise change in the contact pressure is possible.
  • the relative position of the sleeve 114 and the grinding block base plate 116 makes it possible at any time to read off the current pressing force with the aid of a scale if the spring characteristic of the spring used is known.
  • this eliminates the need for complex hydraulic equipment on the machine and, on the other hand, not only determines how finely the setting of the contact pressure can be changed by using springs with different characteristics, but also by using several springs that run into one another within a sleeve 114
  • any connection between the feed path and the change in the contact pressure can be set by using a progressive or degressive spring behavior, which can be achieved most simply by using several springs within a sleeve 114.
  • a different spring 119 can be used in the two sanding block holders 109, so that the contact pressure of one sanding block 105 differs from that of the other sanding block 105, which is particularly useful when the two sanding blocks are equipped with different grain sizes.
