Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Industrial Field of Application] The present invention is useful for rough finishing in the ceramics industry, especially when the surface of a pre-fabricated surface, such as a teacup handle or a lid knob, is used. This invention relates to a device for mechanically attaching hard parts to prevent them from slipping.

[Conventional technology]

Devices for supplying ceramic parts to be attached, in particular handles and bowls, are known. East German Economic Patent No. 2102
Such a device according to No. 30 comprises a vertically movable lifting unit with a non-self-locking adapter for carrying the dough profile receiver, a stopper unit, a special support plate, a negative pressure connection. A swiveling unit with a part and a distribution member, and a handle unit which can be swiveled by means of a stepping motor, are provided on a chain transport unit. The characteristics in this case are
The bowl holder and the handle holder are brought to a predetermined position.

Another device for transmitting mechanical vibrations for supplying ceramic parts to be installed and for carrying out the installation process is described in East German Economic Patent No. 146,414.

The green bodies to be applied are fed by means of a step-by-step rotary table into a grooved green body receptacle. In this case, the positioning of the groove in the dough profile receptacle is achieved by a lever-roller arrangement. An elastically formed vibrating rod fixed to an exciter movable vertically and horizontally is inserted into the groove of the dough forming body receiver positioned in this way, and the dough is formed by horizontal movement. Pressed against your body. In this case, at the same time, the unit presses the flat end of the handle receiver against the molded body.

Such a device is based on the following principle.

The principle is that the ceramic body to be mounted, in particular the teacup, is positioned by a feeding unit and excited at the mounting point by a vibration transmission unit.

Disadvantages of the known device are the high technical cost of the device, the number of cycles that can be achieved is too low, and the mounting However, the mounting parts have to be positioned dimensionally, and the proximity or contacting of the parts to be connected is inaccurate or requires the use of expensive sensor or adjustment techniques. . With known devices, it is not possible to securely mount components, such as the handle of the teacup, during the manufacturing process. Furthermore, in the case of known mounting flaps, when they are opened after the mounting process, the parts to be mounted, in particular the handles, may slip out of their normal position.

[Purpose of the invention]

The object of the invention is that a prefabricated ceramic part can be attached to a dough molding, in particular a handle in a non-slip manner on a teacup, and that the above-mentioned disadvantages can be eliminated, i.e. the technical costs of the equipment can be reduced. Another object of the present invention is to provide an apparatus in which the seating and position of parts to be attached are consistent and a reliable attachment process with a high number of cycles is guaranteed.

The problem underlying the invention is that, with low equipment technical outlay, the feeding and positioning of the dough profile and the vibration transmission are combined into one unit, and the contact between the prefabricated part and the dough profile is made possible. It is an object of the present invention to provide a device for performing slip-free installation by mechanical vibration, in which the installation process is guaranteed.

[Structure of the invention]

According to the present invention, the above-mentioned problem can be solved using a known cylinder,
In accordance with the invention, a vibration transmission unit is integrated in the stopper unit and in the non-self-locking adapter, so that the excitation bar of the exciter or its extension simultaneously
The solution is to provide an adapter that does not have a self-locking effect, which acts as a dough receiving IJ and thus also as a carrier for the dough molding. The upper region of the excitation bar is designed to be elastically bendable.

The mounting part receptacles for the prefabricated mounting parts are designed to be movable, especially in the case of handles. i.e. even after closing the mounting flap.
The mounting parts holder remains at 41 movable. In this case, the frequency range for excitation exceeds the conventionally known value, depending on the shape and material of the dough molding and mounting: y parts.
0 i1z to 800 fiz. In a preferred variant of the device according to the invention, an additional horizontal exciter is arranged at the height of the elastic range of the exciter bar.

〔Effect of the invention〕

By forming the upper range of the excitation protrusion elastically and restricting the movement of the attached parts receiver with a stopper,
The contact surfaces and connection surfaces between the prefabricated ceramic parts and the raw @kai form become uniform. When the pre-fabricated parts inside the mounting parts holder are brought close to the dough molded body by the mounting unit, the dough molded body is pushed out from the zero position, and the mounting parts holder and the pre-fabricated parts to be mounted are movable. In connection with this, even if the two ceramic parts do not fit together, this can be compensated for. The adaptation of the green body of ceramic material, the prefabricated parts, the contact surfaces and the connecting surfaces is made even better by the horizontal exciter which is additionally provided in the elastic region of the exciter bar.

Embodiment I An embodiment of the device of the invention will now be described with reference to the accompanying figures.

A special dough receptacle 2 is intermittently fed with dough moldings 1 by means of a suitable conveyor boulder 4, for example a chain or a rotary table. Combined lifting /
The contact/excitation unit is constructed as follows.

On the lifting cylinder II, there is an exciter equipped with an excitation rod 5 containing a swallower 3! 0 and a sleeve 9 with a guide bearing 7 for the excitation rod 5 are fixedly arranged. The casing 8 and the stopper part 6 accommodate a sleeve 9.

The dough moldings 1 together with the dough molding receiver 2 are in the transport holder 4 at the start of the process, said unit being lowered in such a way that the adapter 3 is located below the transport holder 4. Above the unit, a mounting holder 18 coated with an elastic soft material is centrally arranged in a known manner in a vertically adjustable and lockable manner.

Horizontally movable mounting unit with stroke limited by adjustable stop 16! 5 is a mounting flap 1 which can be opened in particular by 90°;
4, this mounting flap also carries a mounting part receptacle 13. In this case, after receiving the prefabricated single part of ceramic material and closing the mounting flap 14, the mounting part receptacle 13 is rotatable, limited by the adjustable stop I7. In FIG. 1, the mounting flap 14 is in the open position and the prefabricated part 12 is in the positioned position. That is, the attachment flap 14 is closed. The excitation protrusion rod 5 is formed as follows. That is, the lower end between the clamping part of the exciter 10 and the guide bearing 7 of the sleeve 9 is rigid, and the upper end between the guide bearing 7 and the swallower 3 is elastic.

This is achieved by means of a different material, for example glass fiber/steel, or, as in the exemplary embodiment, by means of a cast material, for example by means of a cast material with a cross-sectional area of 5 d. The normal state is that the excitation rod is in a relaxed state, that is, in a vertical state.

The operation of the device is as follows.

From its lower end position, the lifting cylinder 11 lifts the exciter 10
upwards, thereby lifting the sleeve 9 containing the guide bearing 7 and the excitation rod 5 containing the adapter 3;
Therefore, the dough molded body 2 is transferred together with the dough molded body L to the boulder.
Push out from 4. The lifting process is limited by a stop 6, thereby completing the positioning of the dough profile l.

During the vibration process, the mating holder 18 ensures a positive contact between the dough molding 11, the dough molding support 2, the adapter 3 and the excitation rod 5.

The prefabricated part 12 is, as is well known, a dough molded body l.
Parallel to the transport and positioning of the mounting parts receiver! Part 12 inserted into 3 and made P
is inserted so that the end thereof protrudes from the attachment part receiver 13. At that time, the mounting flap 14 is opened and the 1
5, preferably in the water shell position. By moving the installation l 4'l'7(71'f), the preparation of the prefabricated part 12 is completed and the installation process can begin.

For this purpose, the mounting unit 15 is moved up to the adjustable stop 16. The stopper 16 is adjusted as follows. That is, the end of the prefabricated part 12 is adjusted in such a way that, together with the green body 2, the adapter 3 and the excitation rod 5, the green body 1 is pushed out of its normal position. The spring force generated in this case and the movement of the mounting part receiver I3 between the stops 17 ensure abutment of the ends of the prefabricated parts 12. Mounting unit 15
The exciter 10 starts operating at the same time or a little later when it hits the stopper 16, whereby the prefabricated part 12 is attached and fixed to the dough molded body l. By adjusting the stopper 16, the difference in position between the normal position and the dough molded body 1 can be adjusted as desired at the start of the attachment process. As a result, the dimensional and shape differences between the prefabricated part 12 and the dough molded body ■ are compensated for,
The necessary clamping forces of the ceramic parts during the mounting process are compensated.

After finishing the mounting process, the mounting flap 14 and the mounting unit I5 return to their initial position. As a result, the lifting sill 11 lowers the vertical unit to its initial position. In this case, the dough profile I, together with the attached prefabricated part 12 and the dough profile carrier 2, is placed again in the transport holder 4, and this transport boulder is advanced by one pitch, whereby the next dough Molded body 1
supply. Therefore, the cycle begins anew.

Embodiment 2 In a preferred variant, a horizontal exciter unit 19 is additionally arranged. This exciter unit consists of a cylinder equipped with an exciter and a boulder for the excitation rod, and is provided at a height within the elastic range of the excitation rod 5 in the apparatus shown in Embodiment I. The horizontal exciter unit 19 is then moved up to the adjustable stop 20 . This stopper can be adjusted as follows. That is, the horizontal excitation protrusion can be adjusted so as to contact the excitation protrusion 5 at the rest position, or alternatively to be biased and brought into contact with the excitation protrusion 5 at the rest position. With both structures, the excitation for the mounting process can be performed horizontally and vertically, i.e. in combination, with separately adjustable frequency and amplitude to assist in a slip-free mounting process.
