[Detailed description of the invention] [Industrial field of application] The invention is an insertion device for inserting at least one heat-insulating rod into a receiving groove of a metal molded body to form a heat-insulated composite molded body. , at least one guide device consisting of lower and upper guide rails for the insulating rod and a drive device are provided by which the insulating rod can be pushed through the guide device. relating to a certain form of thing.

[Prior Art] The insertion of a heat-insulating rod into a receiving groove of a metal molded body to form a heat-insulated composite molded body has heretofore been carried out entirely manually.

The metal moldings, usually about 6 m long, are placed on an assembly table, the insulating rod is first inserted into the receiving groove of the first metal molding, and then the second metal molding is inserted into the first metal molding. is fitted over the insulating rod already bonded to the insulating rod.

In composite moldings having two or more insulation rods, a corresponding number of insulation rods are first fitted onto a first metal molding, and then a second metal molding is fitted over the latter.

The assembly time required for this is quite long and the insertion of the insulation rod requires considerable skill. This is because such long insulating rods are unstable and the operator can only grasp each insulating rod to be inserted at a short distance from the insertion end of the metal molding. be.

[Problems to be solved by the invention] An object of the invention is to improve an insertion device for inserting at least one heat-insulating rod into a receiving groove of a metal molded body to form a heat-insulated composite molded body. The aim is to enable quick and problem-free assembly.

[Means for Solving the Problems] The gist of the present invention for solving the above problems is that the length of the guide device is several times the height of the heat insulating rod, and
A drive roller is provided as the drive, which can be pressed against the heat-insulating rod at the recess in the lower guide rail.

Such an insertion device results in a significant reduction in assembly time in the formation of thermally insulated composite moldings. This is because the insulating rod, which is inserted into the guide device and which is inserted with its front end into the receiving groove of the metal profile, is inserted into the receiving groove of both metal profiles by the drive device without any other manual intervention. This is because it will be done.

If it is desired to assemble a composite profile with two or more insulation rods, a corresponding number of guide devices are provided, so that the assembly of such a composite profile can likewise be carried out in a single operation step. .

According to a particularly advantageous embodiment of the invention, this guide device is arranged on one end side of an assembly table which receives the metal profile and has a corresponding support on the other end side.

In this way, the metal profiles to be joined simply need to be placed on the assembly table, after which the front end of the insulating rod is inserted into the corresponding receiving groove of the metal profiles and the drive is switched on. Since this insulating rod is inserted into the metal profile without any other means, the device of the invention either positions both metal profiles or fixes them at right angles to the longitudinal direction of the metal profile. No other means are needed to do so.

The insulating rod is correctly guided in the guide device and the distance between the guide device and the end face of the metal profile is selected such that the insulating rod does not break in this area and is therefore ultimately considered rigid. There is.

Embodiment The device 20 shown in FIGS. 1 and 2 is for inserting an insulating rod 3 into a metal molding 1, 2. The device 20 shown in FIGS.

The metal molded bodies 1, 2 and the heat insulating rod 3 form a thermally insulated composite molded body, as is clear from FIG. 4, for example.

The device 20 has two guide devices 21 and one drive device 22 for one insulating rod 3 in each case.

The guide devices 21 each have a lower guide rail 2
3 and an upper guide rail 24.

The two guide rails 23, 24 of each guide device 21 each guide one insulating rod 3 exactly along its longitudinal axis.

The length of this guiding device 21 is several times the height of the insulating rods 3, so that precise guidance in the longitudinal direction of each insulating rod 3 is guaranteed.

The lower guide rail 23 has a recess 25 approximately in its central region, the depth of which is such that the lower edge of each insulating rod 3 is free, as is particularly clear from FIG. given to be accessible. A driving roller 26 is located in the range of this notch 25.
A drive device 22 is provided which is configured as a.

This drive roller 26 is mounted between two pivot levers 27 and is driven via an electric motor 28 and a timing belt transmission 29.

The two pivot levers 27, which are connected to each other by a shaft 30, can be pivoted by a manually operated lever 31 by a certain limit.

As is clear from Fig. 2, this turning lever 2
7, the drive roller 26 is pressed against the insulation rod 3 in the area of the recess 25 or pulled away from it.

When the drive roller 26 is pressed against and driven by the heat insulating rod 3, it rotates in the direction of rotation shown by the arrow in FIG. 2 and conveys the heat insulating rod 3 through the guide device 21 in the direction of arrow A.

As shown in FIG. 1, this drive roller 26 is provided with a cross knurl 32 on its outer peripheral surface. This cross-shaped knurl 32 ensures perfect forwarding of the insulation rod 3.

Naturally, it is also conceivable to provide another means for increasing the friction value on the outer peripheral surface of the drive roller 26.

To facilitate the transport of the insulation rod 3, the upper guide rail 24 can be provided with rollers, needles or similar means in the area of its contact with the insulation rod 3.

The insulation rod 3 has a metal molded body 1 at its front end.
It is inserted into the receiving groove 8 of No. 2. In order to facilitate this insertion, the insulating rod 3 is designed, in accordance with earlier proposals by the applicant, without a fixing web at its front end. This allows effortless insertion into the receiving groove 8.

Once this insertion into the receiving groove 8 has taken place, the drive roller 26 is pressed against the insulating rod 3 and the previously described forwarding of the insulating rod 3 takes place.

The insulating rod 3 is now inserted into the receiving groove 8 of the metal profile 1, 2 without further manual intervention.

As clearly shown in FIG. 3, the metal moldings 1, 2 are placed on an assembly table 33. This assembly table 33 is provided with a corresponding receiver 34 on its end surface side, and this corresponding receiver 3

The device 20 is arranged on the other end side of the assembly table 33. As shown particularly clearly in FIG.
5, this device 20 can be moved parallel to the front end face of the assembly table 33.

The operator first brings this device 20 to a suitable position in front of two metal moldings 1, 2 located one above the other. Both insulating rods 3 are then inserted into the device 20, as clearly shown in FIG.
Following this, the metal molded bodies 1 and 2 to be assembled are inserted into the receiving groove 8 as described above.
Thereafter, the electric motor 28 is switched on simultaneously with the pressing of the drive roller 26 against the insulation rod 3. The insulation rod 3 is now automatically inserted into the end-supported metal profiles 1, 2.

Advantageously, the upper guide rail 24 of the guide device 21 is arranged to be movable in the vertical direction.
This is because the guide device 21 can thus be easily adapted to insulation rods 3 of different sizes. It is likewise advantageous to arrange at least one of the guide devices 21 so that it can be moved horizontally.

As is clear from Fig. 2, the drive roller 2
The swivel lever 27, which bears 6, is at an angle of 45 DEG to the longitudinal axis of the guide device 21. The shaft 30 of this pivot lever 27 is located behind the drive roller 26 in the transport direction of the insulation rod 3.

[Effect of the invention] With this configuration, self-retention of the pivotably supported drive roller 26 is provided with a frictional connection being obtained between the drive roller 26 and the heat insulating rod 3. In addition, metal molded bodies 1 and 2
With a high resistance to the insertion of the insulating rod 3 into the receiving groove 8 of the insulating rod 3, a fairly strong automatic pressing of the drive roller 26 and thus also a fairly high forwarding force for the insulating rod 3 is produced. Summer.

Furthermore, as is clear from FIG. 2, a limit switch 36 is provided in the swivel range of the swivel lever 27, and as soon as the drive roller 26 is disengaged from the insulation rod 3, this limit switch 36 is activated.
The electric motor 28 is switched off via 6. On the other hand, when the drive roller 26 is swiveled in the height direction via the lever 31 and pressed against the heat-insulating rod 3, the electric motor 28 is switched on via the limit switch 36.

In contrast to the illustrated embodiment, the device 20 can also be provided with only one guide device 21;
It is also conceivable to provide more than two guide devices 21, depending on the respective desired purpose of use. The device 20 may be assembled to the assembly table as shown in FIG. 3, or it may be provided as a stationary unit immediately adjacent to the end face of the assembly table 33.
