Description

[0001] The invention relates to a machine bed for a glass forming machine, in particular for an IS or an ISX glass forming machine, on which stations of the glass forming machine are arranged.

[0002] Such a machine bed typically serves to accommodate a large number of stations, each with a pre-forming and a finishing side, which can be arranged in any number on the machine bed. When installing a glass forming machine, its machine bed is designed and built according to the desired number of stations.

[0003] Based on the prior art described above, the invention aims to further develop a machine bed for a glass forming machine in such a way that it can be manufactured with significantly less technical and design effort for glass forming machines with a wide variety of station numbers.

[0004] This problem is solved according to the invention by constructing the machine bed of the glass forming machine from at least two separate machine bed modules, which can be brought into a fixed engagement with one another to form the machine bed of the glass forming machine. Such machine bed modules can be arranged in any number and brought into a fixed engagement with one another. Thus, machine beds for glass forming machines with any number of stations, e.g., with 2, 4, 6, 8, 10, or 12 stations, can be built with comparatively little effort, without having to produce a special machine bed as a unit with the corresponding predefined dimensions for each station. This makes the installation of machine beds for glass forming machines considerably more flexible. Depending on the requirements, it is possible to assemble the respective machine bed directly on-site at the customer's or customer's premises.This is particularly important when there are restrictions regarding the transport routes to the installation site of the machine bed.

[0005] Conveniently, each machine bed module can accommodate two stations of the glass forming machine. Accordingly, these machine bed modules can be used to assemble or construct machine beds for glass forming machines with any even number of stations.

[0006] A firm connection between adjacent machine bed modules is achieved with minimal effort if the machine bed modules preferably have two T-nut receptacles on their side surfaces facing adjacent machine bed modules, wherein a T-nut can be positively inserted into each recess formed by two T-nut receptacles of adjacent machine bed modules, by means of which these two adjacent machine bed modules can be firmly connected to each other.

[0007] To prevent a T-nut from slipping out of the T-nut receptacle into which it has been positively inserted, it is advantageous if the T-nut receptacles of the machine bed modules have a stop wall on their underside that holds the T-nut in the T-nut receptacle.

[0008] To further enhance the strength and stability of the connection between adjacent machine bed modules, each module can be positively connected at each of its four corners to the corresponding corners of adjacent modules by means of a connecting plate, preferably designed as a double-T plate, using screw connections. Ultimately, this allows for a virtually one-piece design of the machine bed constructed from the machine bed modules.

[0009] If at least one, preferably each, machine bed module has a storage device for an interchangeable station of the glass forming machine, which is adjustable between a rest position in which the interchangeable station can be fixed in its operating position on the machine bed module and a lifting position in which the interchangeable station can be lifted from its operating position and led out of the glass forming machine on the storage device, defective stations of the glass forming machine can be replaced with a small expenditure of time.

[0010] Bearing elements of the bearing assembly of the machine bed module can advantageously be designed as roller, cylinder or journal bearings.

[0011] The storage elements of the storage facility assigned to a station can advantageously be arranged in two rows, with each row being assigned to an edge area of ​​the station.

[0012] A further simplification is achieved if each storage device can be adjusted between its rest position and its lifting position by means of an adjusting device, whereby the adjusting device can be driven manually, electrically, pneumatically or hydraulically.

[0013] If each machine bed module has a separately controllable operating air connection for each preform and each finished form side of the stations arranged on the machine bed module, each preform and each finished form side of each station of the glass forming machine can be supplied with adapted air volumes and air pressures according to the requirement profile, resulting in significant improvements in the production of glass articles.

[0014] Precise positioning of the machine bed is achieved if at least one, preferably each, machine bed module has a vertically adjustable machine foot at each of its corners.

[0015] The invention will now be explained in more detail with reference to one embodiment and the drawing, the only feature of which is... Fig. Figure 1 shows a perspective view of a machine bed module of the machine bed according to the invention.

[0016] A machine bed according to the invention, described in more detail below, comprises at least two machine bed modules 1. Such a machine bed module 1 is in Fig. Figure 1 shows one embodiment. In the illustrated embodiment, such a machine bed module 1 can accommodate two stations of an IS or an ISX glass forming machine. In principle, such a machine bed module can be designed for any number of stations.

[0017] Machine beds for glass forming machines of any size or number of stations can be assembled from such machine bed modules.

[0018] The in Fig. The machine bed module 1 shown in Figure 1 has a right-hand side surface 2 and a left-hand side surface 3. In the illustrated embodiment, two T-nut receptacles 4 are formed on or in each of the two side surfaces 2 and 3. The right-hand side surface 2 faces the left-hand side surface of the machine bed module 1 to its right, and the left-hand side surface 3 faces the right-hand side surface of the machine bed module 1 to its left. The corresponding T-nut receptacles 4 of adjacent machine bed modules 1 form recesses into which a T-nut 5 can be positively inserted, as indicated on the right-hand side surface 2 of the machine bed module 1. By means of the T-nuts 5 inserted into the recesses formed by the corresponding T-nut receptacles 4, adjacent machine bed modules 1 can be firmly connected to one another – virtually as a single piece.

[0019] At their lower ends are the T-nut receptacles 4, as can best be seen from the illustration of the left side surface 3 of the machine bed module 1 in Fig. 1 is closed by means of a stop wall 6. This ensures that the T-nuts 5 cannot slip out of the recesses formed by the T-nut receptacles 4. The secure – virtually one-piece – connection between adjacent machine bed modules 1 can thus be permanently guaranteed even under high operational loads.

[0020] The connection between adjacent machine bed modules 1 can be further enhanced by connection plates 7, of which in Fig. 1. The connection plate 7, shown at the front right corner of the machine bed module 1, is reinforced and secured. The connection plate 7 is designed as a double-T plate. Accordingly, it is secured by means of Fig. 1 merely indicated two screw connections 8, 9 with the in Fig. The front side 10 shown in Figure 1 is screwed to the machine bed module 1 at its right end. Similarly, the connection plate 7 is screwed to the left end of the front side of the adjacent machine bed module 1 by means of two further screws. After mounting the connection plates 7 at its four corners, the Fig. The machine bed module 1 shown is rigidly and almost in one piece joined with the adjacent machine bed modules 1.

[0021] On its surface section 11, which is assigned to a station of the glass forming machine, the machine bed module 1 is designed with recesses 12 to 19 arranged in two rows. The four in Fig. The recesses 12, 13, 14, 15 provided in the right-hand row are assigned to a right-hand longitudinal edge area of ​​the underside of the station, which are located in Fig. The recesses 16, 17, 18, 19 arranged in the left row are in Fig. 1 assigned to the left longitudinal edge area of ​​the underside of the station.

[0022] In each of these recesses 12 to 19, a bearing element 20 is arranged, which can be designed, for example, as a roller, cylinder, and / or journal bearing element. Each of these bearing elements 20 is adjustable within its assigned recess 12 to 19 by means of an adjusting device 21 between a rest position of the bearing element 20, in which the station is in its operating position, and an operating position of the bearing element 20, in which the station is slidable on the bearing elements 20. During the adjustment movement from its rest position to the operating position, the bearing elements 20 are raised by means of the adjusting device 21 until they protrude approximately 15 mm above the surface of the machine bed module 1, thereby raising the station relative to the machine bed module 1. The station can then be easily pulled out of the glass forming machine on the bearing elements 20. As soon as a new orOnce a replacement station has been moved into its correct position on the machine bed module 1 on the bearing elements 20 which are in their operating position, the bearing elements 20 can be moved from their operating position to their rest position by means of the adjusting device 21, in which the station is lowered onto the machine bed module 1 of the glass forming machine and can be fixed in its operating position on the machine bed module 1 of the glass forming machine.

[0023] The adjusting device 21 for raising and lowering the bearing elements 20 located in the recesses 12 to 19 can be operated manually, but an electric, pneumatic and hydraulic drive is also possible. Automatic operation is preferable.

[0024] The in Fig. The machine bed module 1 shown can accommodate two stations. On its surface section 11 assigned to one station, the preform side of the station is located on the section closest to the front, and the finished mold side of the station is located on the section furthest from the front. The machine bed module 1 is equipped with an operating air connection 22 on the preform side and an operating air connection 23 on the finished mold side. Each operating air connection 22, 23 is separately controllable.

[0025] At its four corners, the machine bed module 1 is provided on its underside with a height-adjustable machine foot 24, of which in Fig. Only the two machine feet 24 located near the front 10 and one of the two rear machine feet 24 are visible. This allows each machine bed module 1, and thus the machine bed of the glass forming machine, to be positioned exactly horizontally and plumb.
