Definitions

  • the invention relates to a display unit according to the preamble of claim 1.
  • a display unit of this type is already known from DE-OS 31 34 356.
  • this has the disadvantage that two conveyor belts are used, which must have a not inconsiderable elasticity in the region of the bend due to the transport rollers in order to be able to form the different bending radius.
  • elasticity must be avoided with long conveyor belts, otherwise they will sag and are not taut.
  • balls are used as display elements in the known display unit.
  • display units which have display elements which are rotatably arranged in a display area and which do not cause the display by presence or absence but by rotation by 180 °. You have e.g. a white area on one side and a black area on the other side.
  • the object of the invention is to overcome these disadvantages and to realize a display unit which is very cheap, thus avoiding both high material costs and high labor costs and can therefore find widespread use in areas where display units of these are used for cost reasons Art could not previously be used.
  • a display unit mentioned at the outset in that the display elements only partially punched out (or cut out or etched out) parts of a conveyor belt are connected to the conveyor belt in relation to the direction of movement to the side of these parts (e.g. when moving horizontally below or preferably above the parts) and which, depending on the character to be displayed, are either in front of or behind separating strips in the display area, which show the visible and invisible positions separate the display elements so that the setting device moves the display elements so that they come in front of or behind the separating strips when the transport belt is transported further and that the transport belt with the display elements has a contrasting color relative to the separating strips.
  • This arrangement according to the invention has the extremely important advantage for mass products that when the wear parts age and wear, any layperson can replace them and the wear parts are not expensive.
  • the replacement of the conveyor belt with the display elements in the display unit according to the invention is no more difficult than the replacement of an ink ribbon in a typewriter. Since the display elements and the conveyor belt form a unit, neither additional work nor costs are necessary to replace the display elements at the same time.
  • Another very important advantage of the display unit according to the invention is to make the displayed font visible on the front and on the back without the need for two setting devices.
  • Fig. 1a shows a section of a conveyor belt 1 according to the invention.
  • 2 are the transport holes for the transport through the spiked rollers.
  • 3 are the three-sided cut-out display elements, which remain connected to the conveyor belt with their fourth side (above) and form a unit with the latter.
  • the ratio of display element to environment is better here than in the variant shown in Fig. 1b.
  • 1b shows another variant in which the display elements are round and remain connected to the conveyor belt over a range of approximately 60 °.
  • the only advantage of this variant is that the punching tool is simpler.
  • Fig. 2 again shows a section of the conveyor belt 1 with two display elements 3, which are bent away to the rear.
  • FIG. 3 shows the representation of the area of a display element which lies behind its separating strip 4.
  • the separating strip has a contrast color relative to the conveyor belt 1.
  • Fig. 4 shows the side view of two display elements 3 and two separating strips 4, which are formed here by the front surfaces of two U-profiles 5 and a section of the conveyor belt 1.
  • the front surfaces of the U-profiles serving as separating strips are above by e.g. 30 ° ... 45 ° beveled to offer the display elements 3 a support with this angle.
  • Fig. 5 shows the right part of the front of a frame of the display unit without a conveyor belt.
  • 4 are the separating strips, namely the front sides of the U-profiles 5.
  • 6 is the right frame of the frame, to which the U-profiles 5 and the mounting brackets 11 are attached.
  • 7 is the right transport roller, which consists of spiked rollers 8 and 9 support discs. These support disks support the conveyor belt between the display elements.
  • 10 are the tip-shaped ends of the separating strips which engage between the support disks 9 of the right transport roller.
  • 11 are bearing brackets in which there are, for example, ball bearings for the transport roller.
  • FIG. 6 shows how a display element 3 is pushed inwards between the support disks 9 by a bolt 13 of a magnet 12.
  • the support disks 9 are separated from one another by spacer rings 18. Both are on the shaft 19 of the transport roller.
  • the support disks are drawn in section here. It can be seen that they have grooves 14 on the edge into which the display elements 3 are pushed with their lower edge.
  • the bolt shown when pushing
  • this display element is thus conveyed through the tips 10 behind the separating strips after a rotation of approximately 90 °.
  • the relevant display element remains in front of the front edge of the support disc and is guided through the tips 10 in front of the relevant separating strip during further transport.
  • An essential feature of this method of operation is that the upper edges of the support disks are higher than the lower edges of the display elements.
  • the material for the conveyor belt with its display elements is a glass fiber reinforced fabric, which is coated on both sides with thin plastic film is very suitable. This material is extremely tensile, can be easily punched, the tape itself and the display elements are very flexible and can be easily bent by the bolts so far that they jump into the grooves. Wear at the transport holes only occurs after very long use.
  • the ends of the tape can be permanently joined into a loop by sewing and gluing.
  • the color of the plastic layer makes it easy to choose the desired color.
  • the upper edges of the support disks for the left transport roller are also higher than the lower edges of the display elements.
  • the left ends of the separating strips owing to their beveled upper edges, guide the display elements behind them into the grooves of these support disks and the display elements in front of them in front of the front edge of the support disks.
  • the separating strips on the back have the same tips 10 on the left roller as the front separating strips have on the right. You again select the display elements (as on the front) in front of or behind the dividing strips on the back of the display unit.
  • the front separating strips with the separating strips on the back can be covered with separating strips in order to also display on the back circular curved sheets connect that engage between the support washers.
  • the upper edges of the support disks must be lower than the lower edges of the display elements.
  • Fig. 7 shows the right part of the frame of the display unit without a conveyor belt from above.
  • the same numbers as in the previous figures are used for the same parts.
  • the guide plate 15 is attached, which leads all display elements of the conveyor belt, not shown, to the front edges of the support disks, which have the same diameter as the spiked roller 8 and in this figure are covered by this.
  • the slot 21 of the bearing bracket 11 through which this bearing bracket is displaceable.
  • the threaded hole 30 in the frame frame is used to attach a large U-profile, not shown, which forms the upper part of the housing enclosing the frame.
  • the display unit works as a "passive display”, i.e. it does not shine itself, but must be illuminated with the ambient or daylight. If you want to use the display unit according to the invention as an "active display”, another type of design of the separating strips must be selected.
  • the dividing strips are now not the front of U-profiles, but the front of a solid display board that has grooves to accommodate the invisible display elements.
  • Fig. 8 shows the section through such a display board 24.
  • 1 is the conveyor belt.
  • the dividing strips 4 are here the parts of the front surface of the display board which are divided by the grooves 16.
  • a display element 3 of the conveyor belt 1 is located in the second groove from above. At this point, the display element is invisible when viewed from the front and the separating strip 4 there with its contrasting color is visible.
  • this display board must be made of diffuse, but translucent, bright plastic material. The lighting should preferably be from diagonally below.
  • 17 is a light source. Your light reaches the front surface of the display board. If, on the other hand, the display element is in front of the front surface, the area in question remains dark if the display elements are opaque. In daylight, the display unit of this type can still work as a passive display.
  • Fig. 6 is the setting device with the 7 magnets for setting the 7 display elements of a column (at 5 ⁇ 7 - matrix representation) to the right of the right transport roller.
  • This is a place where the space requirement is the least disruptive.
  • the alternative namely to place the setting device in front of the front or behind the rear display surface, is so impractical and spatially disturbing that this can hardly be considered.
  • the bolts have the opposite direction of impact. The display elements are pushed inside out.
  • Fig. 9 shows a section of the front view of the frame of such a display unit without a conveyor belt.
  • the separating surface 4 has a recess 20 where the bolts 13 meet from the inside out, the upper edge of which is again somewhat higher than the lower edge of the display elements, not shown.
  • this arrangement presupposes that all the display elements arriving from the right in the transport direction lie behind part 4a of the separating strip. This can be done, for example, by pressing all display elements in front of the tips 10 with springs into the grooves of the support disks.
  • the disadvantage is that the vertical webs between the display elements touched by these springs and can possibly be scratched.
  • spiked roller 31 presses all display elements with its spikes into the grooves of the support disks.
  • This spiked roller does not need to have its own drive (for example by means of gears on this and the transport roller), because the punched-out display elements themselves can drive this spiked roller.
  • Your storage should be in the housing, not shown, so that by pulling back the bearing bracket 11 between the two rollers 7 and 31 there is a space for removal or for loading the conveyor belt.
  • the magnets can be moved alternately in the horizontal direction by one display element.
  • the data processing device that controls the magnets must then restore the correct assignment by delaying the relevant line data. This is possible in a known manner.
  • the data processing device must also be supplied with start pulses from the display unit when the next display elements have reached the setting position during transport, at which the pushing pins are intended to strike. This is the case if the push pins are approximately in the middle in front of the display elements.
  • start impulses are generated in that a line grid is attached either on a spiked roller or on one of the support disks, which is scanned by a reflection light barrier and the lines are arranged so that the respective impulse is emitted when the setting position is reached.
  • the material of the conveyor belt is made of less flexible material, there is still a much better option.
  • punching the display elements it can be ensured that they get a kink when connected to the conveyor belt at the top and thus have an internal tension that they have from the plane of the conveyor belt at an angle of e.g. Let it protrude 30 ° ... 45 °.
  • a setting device has the great advantage that it can work faster.
  • Fig. 10 shows the section of the side view of such a setting device for two lines of the display unit.
  • the location in the frame of the display unit for this type of setting device is, for example, the same as that shown in FIG. 9. In a slightly modified form, it can also work in the transport roller area.
  • the tongue 35 in Fig. 10 corresponds to the upper edge of the recess 20 of Fig. 9.
  • Fig. 10 it can be seen that due to the internal tension, the display element 3 bends out of the plane of the conveyor belt 1, although it is from the tongue 35 of the spring 36 is prevented from bending further out of the plane. If the magnetic winding 37 is now excited with current, the tongue 36 is pulled downward with its tongue 35 by the magnetic opposite pole 38 and the display element is thus released.
  • the conveyor belt must run from bottom to top.
  • the setting device for the lower roller is the setting device for the lower roller.
  • both bearing brackets can be moved completely parallel above and below by rotating this shaft and thus tensioning the conveyor belt smoothly. This can even be done from one side only, e.g. from above. By fixing the eccentric roller both bearing brackets are then determined.
  • a further development according to the invention is concerned with a setting device which has a setting roller 50, the surface speed of which is equal to the speed of the conveyor belt 1 and which has several (e.g. 8 to 12) electromagnetically influenceable setting pins 51 per row or column, the spacing of which is horizontal and vertical Direction correspond to the distances between the display elements 3 of the conveyor belt 1 and which, depending on the character to be set, protrude from the setting roller 51 or do not protrude (or only slightly) and that the protruding setting pins 51 press the relevant display elements 3 of the conveyor belt 1 into a previous position, which leads behind the dividing strips during further transport.
  • a setting roller 50 the surface speed of which is equal to the speed of the conveyor belt 1 and which has several (e.g. 8 to 12) electromagnetically influenceable setting pins 51 per row or column, the spacing of which is horizontal and vertical Direction correspond to the distances between the display elements 3 of the conveyor belt 1 and which, depending on the character to be set, protrude from the setting roller 51 or do not protrude (
  • this setting device has the great advantage that the setting pins 51 in the setting area have the same speed as the display elements 3. If the setting pins 51 are inadvertently incorrectly controlled, the conveyor belt 1 cannot be torn or damaged because the relative speed is zero or almost zero.
  • the force with which the setting pins set the display elements does not have to be applied by the control magnets, but by the transport motor. As a result, the current consumption of the setting magnets is at least one order of magnitude smaller than if they had to exert the setting force.
  • the movement of the setting pins in the arrangement according to the invention is much slower due to their large number (for example 12 per line) than if only one setting pin were used per line, with the result that the noise generation is considerably lower. This in turn has the consequence that this type of display can also be used in rooms that do not allow a greater noise level.
  • Fig. 11a shows a section A ... A perpendicular through the lower part (for the two lowest lines of characters) of the setting device according to the invention.
  • 11b shows the horizontal section B ... B through this setting device.
  • 50 is the rotating setting roller, in the side holes of which the setting pins 51 are slidably inserted.
  • 52 is the co-rotating bottom of the setting roller, it is supported by the ball bearing 53.
  • the upper cover (not shown) of the setting roller is also mounted.
  • the inner ring of this ball bearing is e.g. connected to the stationary axis 54 with nuts, not shown.
  • a centrally directed line grid is plotted, which is scanned by the reflex light barrier 55.
  • the number of dashes is equal to the number of setting pins per line. As will be shown later, they must form a certain phase angle relative to the setting pins.
  • the reflex light barrier 55 sits on a printed circuit board 56 which is connected to the fixed axis. All of the parts 57 to 64 mentioned below are also fixed on the axis (ie not rotating). 57 are cams, which push the setting pins into the protruding position as they rotate immediately before reaching the setting position. 58 are the axially displaceable supplementary disks, which - if they are in the same plane as the cam disks 57 - supplement the cam disks 57, depending on the character to be set, in such a way that the setting pins remain in the outstanding position.
  • Fig. 11a this is the case with the lower pins.
  • the supplementary disk 58 touches the cam disk 57 and the left set pin cannot be pressed in from the outside.
  • the setting pin above on the other hand, can be pressed inwards in the setting position, because with it the supplementary disk 58 is in a different plane, which lies below the setting pin.
  • they can be moved in the axial direction between the cam disks 57 and the stop disks 64.
  • a brass ring 59 serves as an axial guide.
  • 60 are electrically excitable Magnetic coils which, when excited, lift the respective iron supplementary disks 58 upwards and press them against the brass cam disks 57.
  • iron sleeves 61 on the axis.
  • the coils are surrounded by sheet iron pots 62, which close the magnetic flux on the outside.
  • the axis itself is e.g. also made of brass to prevent magnetic coupling of the electromagnetic systems arranged one above the other.
  • the coils are self-supporting wound on brass sleeves 63.
  • the stop washers 64 are also made of brass or aluminum because of the magnetic decoupling.
  • FIG. 11b shows the upper of the cam disks 57 shown in FIG. 11a and the additional disk 58 underneath which projects with its protruding nose. 62
  • the sheet iron pot is seen from above. Only two set pins are shown in this figure. In reality, e.g. 12 setting pins in each setting line. The number of setting pins per line depends on the distance between the display elements and the diameter of the setting roller.
  • 13b shows it alone in a side view.
  • the coils can be soldered on the inside to the brass sleeves (63) on which they are wound.
  • Their outer wire ends can be led out through side holes in the iron sheet pots 62 and from there through holes 68 in the lugs of the immovable cams 57 vertically downwards and finally soldered to support points on the printed circuit board 56.
  • Continuing thin wires can be soldered to these bases, which lead to the outside through an axial slot in the axis 54. The connection to the light barrier is obtained in the same way.
  • This wire guide hole 68 in the cam plate 57 is shown in FIG. 13.
  • 14a shows separately the sheet iron pot 62, the coil 60, which is wound on the brass sleeve 63 in a self-supporting manner.
  • 14b shows the brass sleeve 59, which is used for the central guidance of the axially displaceable supplementary disk (58).
  • 14c shows the stop disk 64, which decouples the magnet systems and is made of brass or aluminum.
  • the conveyor belt with its display elements is 1.
  • two alternatives of the conveyor belt are shown in FIGS. 1a and 1b.
  • 2 are the transport holes and 3 are the display elements.
  • Fig. 15 19 is the rotating axis of the transport roller
  • 9 is one of the support discs of the transport roller, which are arranged in height so that their front edge 9a is slightly, e.g. lie 1/2 mm above the lower edge of a display element and thus push the display element into an outer position.
  • 14 is a deep groove in the support disc. When they protrude, the setting pins 51 of the setting device can push the display elements into this groove and thus move them into the previous position, which leads behind the separating strips of the display unit during further transport.
  • the section through the transport roller in Fig. 15 is at the same height as the section B ... B through the setting device in Fig. 11. In both parts of Fig. 15 only two of 12 setting pins are shown.
  • the supplementary disk 58 and the cam disk 57 have an angle ⁇ with the axis of the transport roller (in contrast to FIG. 11b). This is the optimal "setting angle" in this example.
  • the direction of movement of the belt and the setting drum are indicated by arrows.
  • the setting pin which is close to contact with the conveyor belt 1 in FIG. 15a and which takes up the angle ⁇ , has just left the nose of the cam plate 57 at its other end.
  • the setting pin can be used a leaf spring 69, but even if this is not used, when in contact with the conveyor belt or more precisely in contact with the indicator element of the conveyor belt located there, it is pushed inwards because the indicator element rests on the outer edge 9a of the support disk.
  • the supplementary disk 58 is in its upper position, it supplements the cam disk 57 and the setting pin cannot be pressed inwards. He then presses the display element over the front edge 9a of the support disc in its groove 14. In this way, the display element in question is "set".
  • phase position ⁇ of the setting pins when the setting first pin has reached the end of the nose of the supplementary disk. Now it could be pushed inwards, but this does not happen because the display element is already in the groove 14. With this phase position, the point in time at which the excitation of the coil in question may be switched off is reached if the next display element is not to be set. In this phase position, the subsequent setting pin is still so far from the edge of the nose of the cam disk 57 that the supplementary disk has sufficient time to fall into its lower position. The angle ⁇ characterizes this phase position. It is the "firing angle" for switching the excitation of the solenoids. At this "firing angle", the switching command is given by the reflex light barrier to the data processing device. The lines on the bottom of the setting roller, which are scanned by the light barrier, must therefore be arranged in their phase relation to the setting pins so that this condition is fulfilled.
  • This angle is referred to as the "ignition angle” because it has a similar function to the ignition angle in the gasoline engine. As with this, it also makes sense here to use an “early ignition”, that is to say an advanced ignition angle, in order to take into account the inertia of the supplementary disc at higher transport speeds.
  • Fig. 15a is additionally a kinked leaf spring 69 (one per line), which - if possible - presses the setting pin inwards. This leaf spring is only necessary if the display elements do not always apply the necessary pressure.
  • 16 shows the right part of the front of the display unit without the conveyor belt and with the setting device according to the invention.
  • 4 are the separating strips, namely in this case the front sides of the U-profiles 5.
  • 6 is the right frame of the frame, to which the U-profiles 5 and the mounting brackets 11 are attached.
  • 7 is the right transport roller, which has spiked rollers 8 and support disks 9. These support disks support the conveyor belt between the display elements.
  • 10 are the tip-shaped ends of the separating strips which engage between the support disks 9 of the right transport roller.
  • 11 are bearing brackets in which there are, for example, ball bearings for the transport roller.
  • 50 is the setting roller with its setting pins 51. In this example, the rotational movement of the setting roller 50 is achieved in that the spikes of the spiked roller 8, which in the transport holes of the conveyor belt, not shown, also engage in the transport holes 70 of the setting roller 50.
  • the fixed axis of the setting device is fastened in the bearing brackets 11 with a view to a simple representation. It is more service-friendly to make the lower fastening of this axis tiltable in order to be able to tilt the setting device to the side when one wants to change the conveyor belt.
  • the upper attachment can then e.g. consist of a snap lock on the upper bearing bracket 11.
  • the drive motor which is not shown here, is a geared motor, the speed-reduced axis of which is connected to the axis of one of the two transport rollers 7.
  • the set pins 51 have inner ends 51a with a larger diameter.
  • the cam discs 57 are arranged here in such a way that the setting pins 51 are pressed outward earlier than in FIG. 15 during their radial movement.
  • the nose of the supplementary disc 58 This is followed by the additional supplementary disc 81 in the radial direction of movement, which may take up a larger angular range than the nose of the supplementary disc 58 because it is no longer involved in the decision "to set or not to set".
  • Its main surface 81a lies in a plane below or above the setting pins. In FIG. 17 it lies below the pin plane and partially replaces the disk 64 in FIG. 11a with its material thickness.
  • the conveyor belt can be guided in such a way that in a part of this angular range the conveyor belt wraps around the setting device with the opposite bending direction relative to the bend around the transport roller.
  • those display elements that are to be set are pressed inwards before they come into the area of the support disks. They are e.g. bent upwards by 45 ° when they reach the front edge of the supporting disc in question and it is not necessary to jump over due to internal bending of the display element. Then even the grooves 14 in the support disks can be omitted.
  • the setting roller 50 is here between the two transport rollers 7 in the immediate vicinity of the right transport roller and no longer to the right of this.
  • the conveyor belt 1 is partially wrapped around the setting roller with an inverted bending radius.
  • the second supplementary disk 81 inside the setting device.
  • the set display elements are lifted over the front edges of the support disks without touching them beforehand.
  • the set pressure is considerably lower and the wear and tear the display elements much lower.
  • the enclosing housing 90 is shorter than if the setting roller were to the right of the transport roller. In this case, in order to be able to remove the tape easily, it is expedient to make the setting roller bendable to the rear. With this tape guide, of course, only the one-sided display is possible, not the display on the back.
