Description

Drive device for a sliding gate and method for its assembly

The invention relates to a drive device for a sliding gate according to the preamble of the attached claim 1 and a drive device according to the preamble of claim 10. Furthermore, the invention relates to a mounting method according to the preamble of the appended claim 12. Such a drive device, such a drive device and such a mounting method are known from DE 10 2005 058 939 B4.

Sliding gate driving devices - e.g. Schiebetorantriebe - usually have a motor rotatably driven gear, which meshes with an applied on the sliding gate to be driven rack.

In the following, a commonly used in the prior art method for mounting such a drive device is explained on a sliding gate. Here, above all, the mounting of the rack is difficult, since the rack must be positioned on the sliding gate such that it occupies a defined height position on the sliding gate. With exact positioning, the rack meshes with the teeth of the gear of the drive device with a predetermined play. This exact positioning of the rack must be done over its entire length. For this purpose, the rack is placed from above on the gear, wherein the gear is not connected to the motor during assembly and therefore is freely rotatable. First, the rack is fixed via a receptacle at a first attachment point. Subsequently, the sliding gate is moved with the rack so that the next shot of the sliding gate exactly above the gear comes to rest. However, for such a mounting method, a disengagement device must be provided between the gear and the motor. This is complex and can only be achieved with special constructions. On the other hand, there are available as mass-produced gear motors on the market, in which the gear via a self-locking gear and the motor is firmly connected. These favorable constructions can not be used with the common assembly method.

DE 10 2005 085 939 B4 discloses a drive device for a sliding gate which comprises a motor, a toothed wheel and a toothed rack fixed in a desired position on the sliding gate. For assembly, the gear is transferred to an adjustment position and then placed as a mounting aid a spacer on at least a portion of the teeth of the gear. The spacer has a sliding surface on its outer diameter, which allows sliding of the rack. In addition, the spacer is dimensioned such that the position difference between working position and mounting position is compensated. After placing the spacer, a rack is placed on the sliding surface of the spacer so as to obtain a target position of the rack. Finally, the rack is fixed to the desired positions on the sliding gate. After fixation, the spacer is removed from the gear and the gear is transferred to the working position, so that the previously fixed rack engages the gear. This method is problematic in checking the correct setting of the target position.

The invention has the object of developing a drive device according to the preamble of claim 1 such that in a simple and inexpensive design a more accurate check the correct setting of the desired position of the rack is possible. This object is achieved by a drive device with the features of claim 1. A drive device provided therewith is the subject matter of the independent claim 10. An assembly method which can be carried out with such a drive device is the subject matter of the further additional claim 12.

Advantageous embodiments of the invention are the subject of the dependent claims.

The invention proposes a drive device for a sliding gate with a drive unit having a motor-driven gear, which is designed for combing with a sliding gate to be fixed rack and is slidably mounted between a working position and a mounting position on a support means, and with an assembly aid for mounting and adjusting the rack on the sliding gate, wherein the mounting aid comprises at least one mounting roller element to be stored removably and rotatably on the carrier device.

The at least one mounting roller is in a preferred embodiment, a mounting gear; but also the use of a roller that can roll on the rack is possible.

The drive device is formed so advantageous that during assembly by means of the support means an exact positioning of the rack in the vertical direction and thus a review of the exact engagement of the rack in the gear is possible, the mounting roller, in particular the mounting gear takes over the role of the gear , The check can be done either by turning the gear or by moving the rack in the horizontal direction. Due to the advantageous embodiment of the drive device, there is no need to integrate a decoupling in the drive device - especially in the power train between engine and gear. The gear can z. B. be transferred via a simple lever mechanism in a working and a mounting position. As a result, cost-effective and mass-produced engines and transmissions can be used for the drive device.

In addition, the drive device has a rigid connection between the motor and the gear wheel. This rigid connection is realized in particular via a self-locking gear, which brings about the positive effect that the sliding gate can not be displaced by applying a force in the axial direction, so that in the closed state the sliding gate can not be opened manually.

Advantageously, the mounting aid for fixing the rack in the desired position at least two mounting rollers on. As a result, the rack can not tilt during assembly. In addition, a smooth running of the rack during positional changes carried out during assembly of the rack in the horizontal direction can be achieved by the use of two mounting roller elements.

As a result, no additional bearing elements must be made, which on the one hand brings a cost advantage and on the other hand allows faster mounting of the mounting roller in the hole or bag opening. In a further advantageous embodiment, it is provided that the gear is surrounded by a gear housing for protection against interference, wherein the mounting roller is attachable outside of the gear housing. This has, on the one hand, the advantage of a protective function during operation and assembly, and, on the other hand, no removal of the gear housing is required during assembly, since the mounting roller element can be introduced directly from the outside into the gear housing.

In a further embodiment, it is provided that the gear housing has laterally projecting housing wings. These serve to accommodate the at least one mounting roller, wherein the laterally projecting housing wings are formed so advantageous that the distance between the mounting roller and the gear is advantageously small. This allows any height differences between the mounting roller and the gear to be kept as low as possible. In addition, the laterally projecting housing wings represent a cost-effective possibility of forming bearing elements for the mounting roller element. The laterally projecting housing wings are designed so advantageous that they can be provided without major expenses with holes or blind holes. Also by the use of two mounting roller elements apply the advantages mentioned above.

Holes or blind openings are advantageously introduced into the laterally projecting housing wing, which serve to receive the mounting roller elements. The holes or blind openings are advantageously mounted so that the required nominal position of the rack, is maintained at correct insertion of the mounting roller elements.

Advantageously, the (entire) drive unit by means of a lever mechanism between the mounting and the working position can be pivoted. The Ausges- As a lever mechanism is a particularly simple design that allows cost-effective production. Furthermore, it can be checked at any time by operating the lever mechanism during assembly, whether the rack has an exact engagement with the gear.

Advantageously, the at least one mounting roller is a mounting gear for engaging in the rack or a mounting roller for rolling when attacking the rack.

In addition to the drive device according to the invention, the drive device according to the invention also has the toothed rack which is thus advantageously to be positioned.

In a particularly preferred embodiment it is provided that the mounting roller element is mounted on the support means such that the target position of the rack is predetermined even when mounted in the mounting position gear that engages the mounting roller element in the rack for fixing the rack, and rotatably mounted the mounting roller is to ensure a displacement of the rack during assembly, and wherein the mounting roller is positioned so that the gear engages in its working position with a predetermined play in the positioning means of the mounting roller rack.

In a further advantageous embodiment, a method for mounting a rack and a sliding door drive device having a cooperating drive device on a sliding gate to be driven by means of a mounting aid, which serves to position the rack in a desired position on the sliding gate, by using a mounting roller, as an assembly aid , In an advantageous embodiment of the method, wherein the drive unit has a gear which can be transferred between a drive position and a mounting position, the following steps are advantageous. First, the gear is transferred to the mounting position, which is below the working position of the gear. Thereafter, at least one mounting roller element, which holds the rack in its required for mounting target position, provided. Subsequently, the target position of the rack is set on the sliding gate on the attack of the rack on the mounting roller elements. Thereafter, the rack is fixed in the target position on the sliding gate and finally the at least one mounting roller is removed and the gear is returned from the mounting position to the working position such that the gear is in engagement with the rack.

Advantageously, the sliding gate is moved to different positions for mounting the rack, in which attack different portions of the rack on the mounting roller. Thus, it can be checked at any time whether an exact setpoint position of the rack is present or any changes in the position of the rack must be made.

Advantageously, the method is applicable to a drive device of the aforementioned type. As a result, an exact assembly is achieved on a sliding gate for a drive device of the aforementioned type.

In a further advantageous embodiment, the mounting roller is inserted into a drive housing. The insertion of the mounting roller element is easier to handle than when this has to be pressed or screwed. By turning the mounting roller element can be advantageously checked whether the rack is in its desired position.

If the mounting roller element is not turned while checking the setpoint position of the toothed rack, it may be necessary to lower the rack until the rack engages the mounting roller element in such a way that the mounting roller element rotates when it is checked again.

Preferably, the at least one mounting roller element is a mounting gear, with which the correct engagement is simulated better than with a roller. In particular, a pair of mounting gears are provided, which are arranged on both sides of the gear.

In the example shown in FIGS. 10 and 11, two rolling elements are shown, wherein the rolling elements are designed here as mounting gears 62. The mounting gears 62 are made of plastic, in particular injection molding and as disposable parts. The mounting gears 62 have horizontally starting from their center via a rearwardly formed bearing shaft, which is not apparent from Figs. 10 and 11. The bearing shaft is designed as a simple pin. With the aid of the bearing shafts, the mounting gears 62 are inserted into the bores or blind openings 50 of the laterally sloping housing wings 56.

With reference to FIGS. 12 and 13, an exemplary embodiment of a mounting method for mounting the drive device 10 to a sliding gate, not shown, will be explained below.

The drive device 12, more precisely the lower housing part 18, is fixed in place at a suitable location close to the sliding gate. The gear 30 is transferred by means of the lever mechanism 28 from its working position to the mounting position. For assembly at least one rolling element is inserted into the gear housing 22. In the embodiment explained in more detail here For example, the two mounting gears 62 are used as rolling elements, which are inserted via their bearing shafts in the holes or blind holes 50 of the laterally projecting housing wing 46. By using two mounting gears 62, tilting of the rack 14 during assembly can be prevented. In addition, a more smooth running of the rack 14 during the displacement of the rack 14 for the required position change during assembly of the rack 14 is ensured by the use of two mounting gears 62. The rack 14 is brought into engagement with the mounting gears 62, as shown in Fig. 12. To check whether there is an exact engagement between the mounting gears 62 and the rack 14, either the mounting gears 62 can be rotated or the rack 14 can be moved horizontally. With exact positioning, the rack 14 moves in the first case or rotate the mounting gears 62 in the second case. If there is no exact engagement between the rack 14 and the mounting gears 62, the rack 14 is repositioned in the vertical direction.

If the rack 14 is in the required position required for the assembly, the rack 14 can be fixed to the sliding gate, not shown. For this purpose, 16 fastening means are introduced via the elongated holes, which produce a connection of the rack 14 with the sliding gate. After a first slot 16 is connected to the sliding gate, the sliding gate with the rack is displaced by a certain portion such that a nearest slot 16 exactly between the two mounting gears 62 comes to a standstill. The slot located between the two mounting gears 62 is also fixed with a fastener with a sliding gate. This process is repeated until all the slots 16 are connected to the sliding gate via fastening means. 14 shows the drive device 10 in the working position with a toothed rod 14 fixed to the sliding gate. For this purpose, the mounting toothed wheels 62 are removed from the bores or blind openings 50. The gear 30 is transferred via the lever mechanism 28 in the working position, wherein the rack 14 has been fixed by means of the mounting gears 62 so exactly on the sliding gate, not shown, that an exact engagement between the gear 30 and the rack 14 is present.

Fig. 15 shows a further embodiment of the drive device 10, wherein the mounting gears 62 are replaced by mounting rollers 64. The mounting rollers 64 also allow exact positioning of the rack 14 in the vertical direction. A horizontal displacement of the rack 14 is effected by horizontal rolling of the rack 14 on the rolling surface of the mounting rollers 64th
