Definitions
- Device for applying seals to doors, in particular vehicle doors and method for applying seals to doors, in particular vehicle doors
- the present invention relates to a device for applying seals to doors, in particular vehicle doors, according to the preamble of claim 1, and a method for applying seals to doors, in particular vehicle doors, according to the preamble of claim 4.
- a device for applying seals to vehicle doors are known. These devices are designed to automatically apply, in particular to glue, a seal in the form of a theoretically infinite sealing tape at a predetermined location on a vehicle door. For seals for doors, especially vehicle doors, water drainage holes must also be provided at predetermined locations.
- a device is known, in particular a stationary rolling system, in which a punching unit, i.e. a unit for introducing holes in the seal, is fixedly arranged between a roller buffer and a stationary cutting and application head.
- the roller buffer stores and dispenses the seal buffered as an endless belt, while the cutting and application head applies and cuts the seal onto the door.
- the system cannot be used or can only be used insufficiently for applying door seals with a significantly shorter length, e.g. for frameless doors, since the geometrically predetermined distance between the punching unit and the cutting knife located in the head with which the endless strip of seal is cut off is: The seal end or the beginning of a new seal is determined is too large for these seals. In other words, for the seal currently to be applied, the water drainage holes cannot be made by the upstream punching unit, since the sealing tape to be applied is already in the cutting and application head.
- this object is achieved by a device with the characterizing features of claim 1.
- the device is equipped with a marking device for marking the sealing start and sealing end of the sealing tape to be applied, an intermediate buffer being provided between the punching unit and the cutting and application head, which is used to buffer sealing tape provided with water drainage holes in front of the cutting and application head is set up, the device can be adapted more flexibly to the length of the seal to be applied, in particular comparatively short seal lengths can be processed, which can be accommodated in the intermediate buffer.
- a marking device preferably the already existing punching device.
- an intermediate buffer in particular a length compensation device, e.g. lifting frame with roller and distance measurement, is provided, which creates a reproducible distance between the start of the seal and the (water drainage) holes.
- the seal start marking can then be detected on the head using a sensor and the signal for the punching unit can be generated.
- the distance between the cutting knife and the punching unit should not be longer than the shortest seal length, especially without intermediate buffer storage.
- the punching unit is designed as a marking device.
- the punching unit fulfills a dual function.
- FIG. 1 shows a schematic representation of a device for applying seals to doors, in particular vehicle doors, according to the prior art
- FIG. 2 shows a schematic representation of a device according to the invention for applying seals to doors, in particular vehicle doors;
- Fig. 3 is a schematic representation of a sealing tape with a hole position and a seal joint.
- the device essentially comprises a roller buffer 1, a punching unit 2, and a cutting and application head 3 with a cutting knife 31.
- the (endless) seal or sealing tape D (hereinafter referred to as sealing tape) is fed to the device via the roller buffer.
- the roller buffer 1 is set up to buffer a predetermined length of the sealing tape D, ie a predetermined length is stored in the roller buffer 1 and can be retrieved from there.
- the roller buffer has, for example, two rollers spaced apart from one another in the direction of gravity, around which the sealing tape is placed in a loop.
- the length to be buffered can be determined accordingly depending on the vertical distance between the rollers and the number of rollers or loops.
- the sealing tape D is transferred from the roller buffer 1 to the punching unit 2.
- the punching unit 2 is set up to punch holes, in particular water drainage holes W, into the sealing tape D.
- the sealing tape D is transferred from the punching unit 2 to the cutting and application head 3. A distance S between the punching unit 2 and the cutting and application head 3 is indicated.
- the cutting and application head 3 is set up to apply the sealing tape D to the door at a predetermined location.
- the cutting and application head 3 is also set up to cut the sealing tape D with the help of its cutting knife 31. Accordingly, the sealing tape D, which is equipped with water drainage holes, is attached using the Cutting and application head 3 is applied to the door and cut off at the appropriate point using the cutting knife 31.
- the result is a sealing strip that runs around the door contour, the ends of which are brought together at a sealing joint.
- the water drainage holes W are made in the sealing tape D at the appropriate location.
- the disadvantage in this context is that the distance S between the punching unit 2 and the cutting and application head 3 can be too long for short sealing tape lengths.
- FIG. 2 shows a schematic representation of a device according to the invention for applying seals to doors, in particular vehicle doors.
- the device according to the invention essentially comprises a roller buffer 1, a punching unit 2, and a cutting and application head 3 with a cutting knife 31. According to the invention it is also provided that the device is equipped with an intermediate buffer 4 and a marking device 5.
- roller buffer 1 With regard to the basic properties of roller buffer 1 and punching unit 2, reference can essentially be made to the statements made above.
- the sealing tape D is transferred from the roller buffer 1 to the punching unit 2.
- the punching unit 2 is set up to punch holes, in particular water drainage holes, into the sealing tape D.
- a marking device 5 is provided for marking the start and end of the sealing tape to be applied.
- the cutting head 31 of the cutting and application head 3 can in turn be controlled from these markings.
- an intermediate buffer 4 is provided between the punching unit 2 and the cutting and application head 3.
- an arrangement between the punching unit 2 and the cutting and application head 3 is that the punched Sealing tape D is first fed to the intermediate buffer 4 and then to the cutting and application head 3.
- the intermediate buffer 4 is basically a buffer that works according to the roller principle. To distinguish it from the already existing roller buffer 1, the intermediate buffer 4 present here is referred to as an intermediate buffer according to its position.
- the intermediate buffer 4 makes it possible for the sealing tape D required for the application to be accommodated in the intermediate buffer 4 with the water drainage holes in the correct position. It is provided here that at least one length to be applied is always buffered in the intermediate buffer, preferably even more than one length to be applied. In other words, the intermediate buffer buffers the sealing tape that is already provided with water drainage holes in the right places and is required for application to the door.
- the method according to the invention for applying seals to doors, in particular vehicle doors, with a device according to at least one of the preceding claims, is therefore characterized by the following method steps: a) transferring a sealing tape D to the roller buffer 1 and buffering a length of sealing tape; b) transferring the buffered sealing tape D from the roller buffer 1 to the punching unit 2 and punching water drainage holes W in the sealing tape D, as well as introducing markings for the beginning and the end of the seal to be applied by the marking device 5; c) transfer of at least one, preferably several, lengths of sealing tape D with water drainage holes W punched for a door application to the intermediate buffer 4; d) transferring the at least one, preferably several, length of sealing tape D with water drainage holes W punched for a door application from the intermediate buffer 4 to the cutting and application head 3; e) applying the supplied sealing tape D with water drainage holes W to a door, in particular a vehicle door; f) Cutting off the sealing tape D with water drainage holes W at the marked point
- a sealing tape applied to a door is shown schematically in FIG. In particular, the position of a water drain hole W and a seal joint A can be seen.
- the seal joint A marks the point at which the sealing tape D is brought together again after a cycle around the door.
