Definitions

  • the invention relates to a punch for sheet and film-shaped material, which has a base in the form of an elongated rectangle and a slot for receiving the material to be punched, and which is provided with punch punches, which by means of a printing device by means of a one-armed to a pivoting pressure lever extending transversely to the connecting line of the punch punch can be pressed onto the material to be punched, and in which the pressure lever has a pressure point at a predetermined distance from its axis.
  • Punchers are special punches that can be used for a variety of purposes. Although one of their main areas of application is the perforation of sheets of paper, they are also used in the metal, plastic or leather processing industries for perforating sheet or sheet material.
  • the force required for punching can be applied by hand or by means of a motor drive. If the force is applied by hand, the known leverage is used for the operation of punch punches in order to punch even thicker sheets or several sheets at once.
  • the spatial arrangement of the lever arm or the lever arms to achieve the leverage is usually such that the holes are bulky and bulky. This in turn usually means that the material to be punched can only be inserted from one direction. Furthermore, most punches do not allow the number of holes to be made in the material to be varied.
  • a letter punch is already known which is suitable for punching hard cardboard, stapled stacks of documents or other materials which can be punched only with relatively great effort (DE-C-20 24 772).
  • This known letter punch has a pressure lever, the pivot axis of which runs transversely to the connecting line of the punch.
  • the disadvantage of this punch is that it does not have a switchover option to different numbers of holes, nor can it be fed vertically with perforated material without the punching process being significantly more difficult.
  • the punch can be actuated by an actuating lever which can be pivoted about an axis, this actuating lever being pivotably mounted on a narrow side of the device (DE-A-20 17 749, Fig. 1, 2).
  • the actuating lever acts on a component that serves for the simultaneous movement of two stamps.
  • a disadvantage of this known hand punch is that it does not have the option of switching to different numbers of holes.
  • an uneven pressure is exerted on the two punch punches.
  • the well-known hand punch also does not allow a pressure element that can be moved, because rod springs serve as the pressure element, which load the punch and support it axially at the same time. The springs thus form abutments for the stamp, which is incompatible with the displaceability of the springs.
  • Punchers are also known in which it is possible to switch from a first number of holes to a second number of holes and vice versa (DE-C-201 252, DE-C-420 124, DE-C-947 462, DE-C-14 36 200 ).
  • these punches have a very wide base area and have a lever which can be pivoted about an axis which coincides with the connecting line of the punch punches or is parallel thereto.
  • the invention has for its object to alternatively change the number of perforations in a punch of the generic type, the force with which the individual punch punches are actuated is approximately the same for all punch punches.
  • the printing device is displaceable parallel to the connecting line of the punch punches in at least two positions, the number of perforations which can be carried out differing from the number of perforations which can be carried out in the second position in the first position, and that the pressure point is arranged essentially symmetrically to the punch punches.
  • the advantage achieved by the invention is in particular that it is possible to vary the number of holes to be punched in a simple manner in a punch of the generic type.
  • the perforated material can be inserted into the perforated slot both horizontally and vertically due to the parallelepiped shape of the perforator. If the hole punch lies on a flat plate with its hole slot facing upwards, the operating lever can still be used because the operating lever itself does not rest on the plate and therefore does not drag on the plate during the operating process.
  • perforations according to a wide variety of standards can be made with the punch according to the invention. For example, it is possible to change from a 2/4 perforation to a 2/3 perforation and thus punch according to the DIN or USA standard.
  • the punch 1 according to the invention is shown in perspective. Its exterior essentially consists of a casing 2, a base 3, a pressure lever 4 and an adjusting lever 5.
  • the base 3 is provided on its underside with a cover 6 which is slightly pulled out in FIG. 1.
  • This cover 6 serves as a collecting container for the circular shredded paper that arises during a punching process.
  • This cover 6 serves as a collecting container for the circular shredded paper that arises during a punching process.
  • This cover 6 serves as a collecting container for the circular shredded paper that arises during a punching process.
  • This cover 6 serves as a collecting container for the circular shredded paper that arises during a punching process.
  • In the base 3 there is also a slot 7 for receiving the paper to be punched. 1, this slot 7 is directed to the side so that the material to be punched can be inserted and punched from the side as usual. But it is also possible to tilt the hole punch by 90 degrees around its longitudinal axis, so that the slot 7 is directed upwards
  • markings 8, 9, 10, 11 are provided on the sleeve 2, which indicate the positions of the punch punches.
  • Further markings 12, 13 are located in the vicinity of the adjusting lever 5. These markings 12, 13 indicate whether two or four perforations are made. 1 is carried out in such a way that the sheet to be punched is inserted into the slot 7 and one end is lightly pressed against a stop 14. This stop 14 is important for the correct perforation, since its distance from the individual punch punches must correspond to the respective standardization.
  • the adjusting lever 5 is used to set whether two or four perforations should be made.
  • the adjusting lever 5 is moved in the direction of the marking 13, while if there are four perforations, it is moved in the direction of the marking 12. In this way, even the less technically experienced can easily change the number of holes.
  • the circular scraps of paper that arise during the punching process fall into the cover 6 and are accumulated there.
  • the sheet can be removed again from the slot 7, because after the force exerted by hand on the pressure lever 4 subsides, the punch punches are brought back into their starting positions by a spring force.
  • motorized operation can also be provided instead of manual operation. For this there is z. B.
  • a touch sensor or an electrical switch when actuated, an electric motor or an electromagnet is activated.
  • This electric motor or electromagnet now pulls the pressure lever down - possibly via certain gears - and in this way effects the perforation.
  • the punch 1 again from one of its narrow sides.
  • the narrow side is formed without protruding edges or other irregularities, so that it offers good protection against injuries.
  • the back wall of the punch 1, i.e. the side opposite the slot 7 is not shown because it only shows the smooth cover, the smooth base 3 and the pressure lever 4.
  • FIG. 3 shows the narrow side of the punch 1, which is located opposite the adjusting lever 5.
  • the base 3 with the cover 6, the pressure lever 4 and the slot 7.
  • the adjusting lever 5 cannot be seen because the pressure lever 4 protrudes somewhat in comparison to the upper edge of the casing 2.
  • the pressure lever 4 is somewhat narrower as the removable cover 2.
  • the slot 7 is relatively wide at its outward end, so that the paper to be punched can be easily inserted. It then tapers so that the paper to be punched is held in a defined position during the punching process.
  • FIG. 4 shows the punch 1 from below, with the cover 6 removed.
  • This cover 6 is pushed from right to left over guide rails 15, 16 up to the stop 14.
  • In the bottom 17 of the punch 1 there are four bores 18, 19, 20, 21 similar to a truncated cone, in the center of which the punch ends 22, 23, 24, 25 can be seen. Due to the frustoconical design of the holes 18.19.20.21, the circular shredded paper is easily detached, i.e. the shredded paper does not jam and easily falls into the receiving space formed by the cover.
  • a screw 26 is provided in the guide rail 16, with which it is possible to firmly connect the casing 2 to the base 3. If you want to remove the cover 2, this screw 26 must first be loosened.
  • the punch 1 is shown from the side, with the casing 2 lifted off and the cover 6 removed.
  • a guide rail 15 and a groove 27 arranged above it can be seen.
  • the paper sheet to be punched slides and rests on this support 28.
  • a U-shaped pressure device 33 is arranged in the support body 29 and around a punch-punch guide 32, which can be displaced in the horizontal direction by a certain amount.
  • the punch-punch guide 32 can be designed as a continuous part with a few openings which assume the guiding function. However, it is also possible for the punch-punch guide to be essentially a hollow tube, in which there are some supporting elements which have through-bores and guide the punch-punches in these through-bores.
  • the adjustment lever 5 is shown above the actual punch.
  • This adjusting lever 5 protrudes through an opening from the casing 2 and carries - not visible from the outside and therefore shown in broken lines - a guide plate 36, which is provided with a guide groove 37 and carries a supporting part, on which a pin 39 is located.
  • This pin 39 engages in a hole in the pressure device 33 when the sleeve 2 is combined with the base 3. By moving the adjusting lever 5, the pin 39 and thus also the pressure device 33 are moved.
  • Fig. 6 corresponds to the representation of Fig. 2, but with the case 2 omitted and the pressure lever 4 is pivoted upwards.
  • the axis of rotation 30 which is designed as a cylindrical pin, one can see from this illustration the support body 29 with the pressure device 33 enclosed therein, as well as the punch-punch guide 32, which is provided in the base 3.
  • a punch 40 protrudes from the punch punch guide 32 and can be pressed down by means of the printing device 33. With 41 and 42, the contact edges for the underside of the shell 2 are designated.
  • FIG. 7 shows a view of the punch 1, which is rotated by 180 degrees compared to the illustration in FIG. 6.
  • the pressure lever 4 is hollow on the inside and has a plunger 43 with which the pressure device 33 can be pressed down. Another punch punch 44 protrudes from the punch punch guide 32.
  • the pressure lever 4 as well as most other parts of the punch 1 are preferably made of plastic.
  • FIG. 8 shows a view from above of the punch 1, with the sleeve 2 removed and the pressure lever 4 pivoted upward, as is indicated by the broken line in FIG. 5.
  • the pressure device 33 has three through holes 45, 46, 47, of which one through hole 45 is provided for receiving the pin 39 and the other through holes 46, 47 for pushing through the punch 40, 44 serve. If the printing device 33 is in the position shown in FIG. 8, the punch punches 40, 44 are not taken along when the printing device 33 is pressed down because they pass through the through holes 46, 47.
  • the other two punch punches which are not under a hole, are pressed down. If the printing device 33 is displaced horizontally, the punch 40, 44 also go outside the area of the through holes 46, 47, and they are taken away during a punching process, i.e. four holes are punched instead of two.
  • FIG. 9 shows a sectional drawing of the punch 1.
  • the two punch punches 48, 49 can be seen here, which - like the two other punch punches 40, 44 - are guided in guide bushings 50, 51, 52, 53.
  • the spring force is applied to the punch punches 49, 44 with a leaf spring 54 which rests on a pin 55 and the ends of which are inserted into bores 56, 57 of the punch punches 49, 48.
  • a gamma-shaped spring 58 is provided, which sits in a bushing 59 and likewise has the ends of the punch punches 40, 61 through bores 60, 61. 48 grab.
  • the same spring type for all four punch punches instead of the two different types of spring.
  • the gamma-shaped spring has proven to be particularly advantageous.
  • FIG. 10 shows a section across the hole 9, seen from right to left.
  • the casing 2 the inner part of the pressure lever 4, the paired support body 29 and the pressure device 33, which rests on the punch 44.
  • a hole is provided in the punch 44, which receives one end of the spring 54.
  • FIG. 11 shows a punch 100 in a sectional drawing which corresponds approximately to the sectional drawing in FIG. 9.
  • This punch 100 differs from the punch 1 according to FIG. 9 in some details. So there is no rail on the punch punches 101-104, but the rail 105 engages in guide notches 106-109 of the punch punch 101-104.
  • These guide notches 106-109 are formed in that the punch 101-104 each have an upper cylindrical and thick shaft 110-113, which is opposed by a flat disc 114-117.
  • the mentioned guide notch 106-109 is provided between the shaft 110-113 and the disc 114-117, which slides in each case in an elongated guide groove 118-121 of the rail 105.
  • Two of the guide grooves, namely the guide grooves 118 and 121 extend obliquely upwards starting from the guide notches 106, 109.
  • the guide grooves 118, 121 take the disks 114-117 with them on their inclined planes as they move from right to left; on the other hand, the disks 115, 116 are not raised because the guide grooves 119, 120 are flat and thus leave the disks 115, 116 at their normal height.
  • the effect of the displacement of the rail 105 is that the two outer punches 101, 104 are excluded from the punching process, because in the raised position they can no longer bridge the spaces 123-126, i.e. a sheet that is pushed into the punch slot is not punched by the outer punch punches 101, 104: the punch 100 works as a 2 punch. In the position shown in FIG. 11, that is to say with a rail 105 shifted to the left, the punch 100 works as a punch of four because the punch punches 101 and 104 have assumed their lower position and can therefore bridge the gaps 123, 126.
  • the spaces 123-126 are expediently provided on both sides with reinforcements 127-132, for example made of a special metal.
  • the punch 100 shown in FIG. 11 is shown in cross section, specifically in a view from left to right. Here one can see the casing 2, the slot 7 and the cover 6.
  • the pressure lever 4 arranged at the other end of the punch 100 can be seen above the casing 2.
  • the disk 114, the shaft 110 and the notch 118 of the punch punch 101 are shown, the punch punch 101 being guided through the bushing 137.
  • the U-shaped rail 105 is suspended in the notch 118 of the punch 101.
  • a reinforcement 141, 142 which corresponds functionally to the reinforcement 127-132, is provided between the socket 137 and a support plate 143.
  • the legs 144, 145 of the pressure lever 4 are pivotable about the bearing pin 30.
  • FIG. 13 shows the punch 100 from above, in a view which corresponds approximately to the view in FIG. 8.
  • the rail 105 can be seen here with its four guide grooves 118-121, the outer guide grooves 118, 121 being provided with the shoulders 146, 147.
  • the guide grooves 118-121 are all constructed in a similar manner. They each have a longitudinal slot 148-151, which at one end merges into a circular hole 152, 154, 156, 157.
  • the discs 114, 115, 117 can be seen at the other end of the longitudinal slots 148-151.
  • a further hole 159 is provided in the rail 105 and serves to receive a pin 122.
  • the two pins 135, 136 with the springs 133, 134 wrapped around them and a screw 160 for screwing the upper and lower parts of the hole punch 100 together can be seen with dashed lines.
  • This screw 160 corresponds functionally to the screw 26 in FIG. 4 .
  • the reinforcement 129 can be seen in the broken piece of FIG. 13.
  • FIG. 14 shows a partial view of the punch 100 from below, with the cover 6 removed. With 183, 184 the folds for this cover 6 are designated, while the reference number 185 indicates a perforation for a pressure stamp.
  • the rail 105 is shown again in isolation and from the side in section. Above the visible side leg 170, the cross section 171 of the crossbar of the rail 105 with the guide grooves 118-121 can be seen.
