Abstract
Description
- The invention relates to a screw driving machine for screwing down roofing material on a roof of a building, comprising a screwing device, a washer holder for washers, a moveable carrier for a washer that is to be screwed down, a means of placing for taking a washer from the washer holder and placing it on the carrier, a screw feeding device, and a means of moving for moving the carrier between a first position under the screwing device and a second position under the means of placing.
- The washers are provided with a hole and are placed under the screw heads in order to distribute the force and to prevent the screws from damaging the roofing material. Such screw driving machines are usually provided with wheels with which they can be moved over the building's roof.
- Such a screw driving machine is known from the American patent US 6.064.189. With the known screw driving machine the washers are stacked and a washer is slid out each time from under the stack by a movable carrier. The carrier brings the washer over an opening in the bottom of the screw driving machine, after which the washer falls through the opening onto the roofing material. Then a screw is inserted in a hole situated in the washer, after which the roofing material is screwed down by means of a screwing device. The washers should be flat, because otherwise they will be held back by the washers lying above and it will not be possible to slide them from the stack.
- An objective of the invention is to provide a screw driving machine of the type described in the preamble in which washers of all shapes can be used. To this end, the screw driving machine according to the invention is characterized in that the means of placing comprises a means of gripping for gripping a washer, as well as an additional means of moving for moving the means of gripping. Because the washers are not slid from a stack, but are gripped one by one from the stack by the means of gripping, it is possible for them to be any shape desired. The washers can, for example, be corrugated.
- An embodiment of the screw driving machine according to the invention is characterized in that the washer holder is attached to the carrier. Because of this, the washer holder can be moved between a position under the means of gripping and a position at a distance from it, as a result of which the means of gripping only has to move in a vertical direction. Preferably, the means of moving can move mainly in a horizontal direction and the additional means of moving can move mainly in a vertical direction.
- Furthermore, the screw driving machine comprises a frame, which is provided with a mainly horizontal first guide, along which the carrier can be moved, and a mainly vertical second guide, along which the screwing device can be moved.
- A further embodiment of the screw driving machine according to the invention is characterized in that the means of gripping comprises a magnet, preferably, an electromagnet. By means of a magnet a washer can be gripped in a simple way. If the magnet is executed as an electromagnet, the washer can also simply be released again. Instead of or in combination with the magnet, the means of gripping may also comprise suction cups, as a result of which washers made of a material not attracted by a magnet can also be used. The disadvantage with this, however, is that the screw driving machine in that case must have a means of producing a vacuum.
- Preferably, the additional means of moving is also a cylinder with a piston which can move in it. In this embodiment, the means of gripping is preferably attached to the piston's free end.
- The invention will be elucidated more fully below on the basis of drawings in which an embodiment of the screw driving machine according to the invention is shown. In these drawings:
- Figure 1 shows a front view of an embodiment ofthe screw driving machine according to the invention;
- Figure 2 shows a view from above of the screw driving machine shown in figure 1;
- Figure 3 shows a side view of the screw driving machine shown in figure 1; and
- Figure 4 shows a side view of the screw driving machine shown in figure 1 during a different stage of the screwing process.
-
- In figures 1, 2 and 3 an embodiment of the screw driving machine according to the invention is shown in a front view, a view from above and a side view respectively. The
screw driving machine 1 is designed for screwing downroofing material 3 on a building's roof. Theroofing material 3 is screwed down at thetops 7 of acorrugated roofing sheet 5, in which washers are placed under the screw heads. - The
screw driving machine 1 is provided withwheels 9 and is moved manually over theroofing material 3 while driving the screws. To this end, thescrew driving machine 1 is provided with ahandgrip 11. Thewheels 9 are attached to aframe 13 on which there is amovable carrier 15 for washers. Thiscarrier 15 can be moved along a horizontalfirst guide 17 situated on the frame, and is provided with astop 19 against which awasher 21 can be positioned (see figure 2). There is aslot 23 in the carrier 15 (see figure 2) through which ascrew 25 is inserted during the process. There is also awasher holder 27 on thecarrier 15. This washer holder is made up of four vertical strips between which astack 29 of washers is situated. - The
screw driving machine 1, furthermore, has ascrewing device 31 that can be moved along asecond guide 33, situated vertically on theframe 13. Moreover, there is a means of placing 3 5 attached to theframe 13, for taking a washer from thewasher holder 27 and placing it on thecarrier 15. In order to move thecarrier 15, thescrew driving machine 1 is provided with a means of moving 37 that is a cylinder with a movable piston in it. Thecarrier 15 can be moved between a first position, in which the washer lying on the carrier is situated under the screwing device, see figure 3, and a second position, in which the washer lying on the carrier is situated under the means of placing, see figure 4. - The means of placing 35 is a means of gripping 39, for gripping a washer, and an additional means of moving 41, in order to move the means of gripping. This additional means of moving 41 is also a cylinder with a movable piston in it and the means of gripping 39 in this embodiment is an electromagnet, which is attached to the piston's free end.
- Furthermore, the
screw driving machine 1 has ascrew feeding device 43. This has a generally known double ratchet mechanism (not visible in the figures) in order to move two discs, provided with teeth, gradually one tooth at a time. These discs take a strip along with them on which the screws are fastened. Thescrew feeding device 43, furthermore, has ascrew guide 45, which guides the screws to a position under a screw head of thescrewing device 31. When the discs are revolved the screws are released from the strip one by one in the known way and fall into thescrew guide 45. There is aclamping device 47 under in thescrew guide 45 that clamps the screw. - In figures 3 and 4 the screw driving machine is shown during different stages of the screwing process. In the first position of the
carrier 15 shown in figure 3, a washer is gripped by theelectromagnet 39. Thecarrier 15 is then moved to a second position shown in figure 4. In this position thewasher 21 is placed on thecarrier 15 against thestop 19. Thecarrier 15 is then moved again to the first position, see figure 3. Ascrew 25 is now inserted in awasher 21 by thescrewing device 31 and partially screwed into theroofing material 3. Here, theclamp 47 releases thescrew 25. At the same time the next washer is taken from thestack 29. Thecarrier 15 is then moved again to the second position, see figure 4. Here, thewasher 21 is stopped by thescrew 25 and thecarrier 15 slides out from under the washer. Thescrew 25 can now be screwed further into theroofing material 3, and the next washer is laid on thecarrier 15. - Moreover, the screw driving machine can be equipped with sensors (not shown in the figures) in order to be able to detect the
tops 7 of theroofing sheets 5. - Although in the above the invention is explained on the basis of the drawings, it should be noted that the invention is in no way limited to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the context defined by the claims.
