Dispensing station of a glass forming machine

The invention relates to a delivery station with a depositing plate for the simultaneous reception of at least two glass objects from a glass forming machine and with a pushing device pushing the glass objects from the depositing plate onto a conveyor belt.

In a known dispensing station of this type (DE-AS 27 46 675 of the applicant) the depositing plate is each Station of the glass forming machine arranged stationary on the machine. The pushing device of each station swings 90 ° back and forth during the pushing cycle back again.

The invention is based on the object of improving the dispensing station and its function.

According to the invention, this object is achieved by that the set-down plate between a take-over swiveling position taking over the glass objects from the glass forming machine and a sliding-over pivoting position which delivers the glass objects to the sliding-over device by means of a swivel drive around a vertical axis of the setting plate is pivotable. This pivoting of the shelf makes it possible to put the glass objects in a

to bring the optimal sliding-over pivoting position for the sliding-over process.

According to one embodiment of the invention, the swivel drive has a rotatably mounted in a housing, attached to the settling plate shaft and a drive motor connected to the shaft. this is a robust construction that requires relatively little effort. The drive motor can preferably be designed as an electric motor,

From the book "Glass Machines" by Giegerich and Trier, Springer-Verlag, 1964, pages 308 to 311, a delivery station is known per se from the Lynch 44 machine, at the set-down plate between a transfer height position that takes over the glass objects from the glass forming machine and a push-over height position that is lower than the takeover height position in the effective range of the pushing device can be moved by a linear actuator. The mouth shapes of the glass forming machine are in the range the delivery station cannot be moved in height. Therefore, the set-down plate must after the opening of the mouth molds (Fig. E 88f) drive down to the level of the conveyor belt to remove the mouths of the glass objects to bring the trajectory of the mouth shapes.

This delivery station, known per se, is improved according to one embodiment of the invention in that in addition to the linear actuator, the rotary actuator is provided. This training is always advantageous when on the one hand the mouths of the glass objects after opening the mouth shapes from the movement range of the mouth shapes removed and on the other hand, e.g. in a glass forming machine designed as a turntable, in an optimal one Slide-over pivot position must be brought before the slide-over process begins. The lifting movement the lowering plate is necessary because the glass counter

would still be in a partially plastic state after leaving the finished molds of the glass molding machine. If one would simply open the mouth shapes in this state in the area of the delivery station and the Dropping glass objects onto the set-down plate over a considerable height would have to entail undesirable changes in shape of the glass objects are expected. This is especially true when the glass objects after leaving the finished molds and before reaching the setting plate, the relatively high building elements of the Run over the glass forming machine, e.g. the sliding device have to. It is assumed that the mouth shapes at least in the area of the delivery station Cannot perform a lifting movement »The same applies if the glass objects are used as transport elements instead of the Muzzle shapes known per se gripper can be used.

From DE-AS 17 04 112 of the applicant it is known per se not to stop the mouth shapes in the area of the delivery station, but to let them continue to run. In the same direction as the mouth shapes, a conveyor belt moves up below the mouth shapes that the glass objects are dropped until their mouths are out of the path of movement of the mouth shapes.

According to one embodiment of the invention, the Swivel drive and the lifting drive combined to form a drive unit. This training saves space and structural Expenditure.

According to a further embodiment of the invention, the drive unit has a housing and one in the Housing rotatably and longitudinally displaceably mounted on the shaft attached to the setting plate, with on the housing a drive motor connected to the shaft via connecting elements is attached. Appropriately is the Drive motor _ *

as an electric motor. He is capable of both
to generate the lifting movement as well as the pivoting movement of the depositing plate.

According to one embodiment of the invention is a
Drive crank of the drive motor via a first uni | universal joint with a connecting rod and the connecting rod | via a second universal joint with one on the shaft | attached connector, with a link § on the one hand via a third universal joint with the an | final piece and on the other hand via a fourth universal | hinge is connected to the housing and wherein a zen | span of the third universal joint is arranged outside a plane running through f a center of the second universal joint and a longitudinal axis of the shaft. These S connecting elements between the drive motor and the
Shafts are simple and not prone to failure and are practically maintenance-free. The universal joints can be designed as simple ball joints. ;

According to a further embodiment of the invention ί the third universal joint is optionally on the one %

or the other side of the plane. This f can be with just a little effort, a pivoting movement
either in one direction or the other. For this purpose, the fourth universal joint is preferably also optionally on one or the other side of the
Arranged level.

According to another embodiment of the invention
is at least one circumferential area of the set-down plate crossed by the glass objects when it is pushed over
defined by a circular arc concentric with the shaft, one existing during the pushing-over

te guarantees in cooperation with the intermediate table, that there is always a constant permissible gap between the lowering plate and the intermediate table, which the Sliding over the glass objects is not hindered,

According to a particular embodiment of the invention, the settling plate is spaced around a longitudinal axis The pivot axis arranged on the shaft is out of alignment with the glass objects arriving from the glass forming machine pivotable. This pivoting is preferably done away from the conveyor belt, so that a previous one Lifting movement of the depositing plate is not required. This pivoting of the setting plate is especially important during when starting up the glass forming machine when the glass objects are not yet perfect. Such defective glass objects should not be pushed onto the conveyor belt or in any way hinder the operation of the machine or impair the faultless glass objects already on the conveyor belt. By swiveling away the shelf, the not yet perfect glass objects can be moved to the Open the mouth shapes in one below the other The cullet return located in the working position of the set-down plate will fall.

According to a further embodiment of the invention the pivot axis is the longitudinal axis of a pivot shaft mounted on the delivery station, with the pivot shaft on the one hand the housing and on the other hand a lever which can be actuated by a swivel motor are attached. The swivel motor is preferably designed as a manually controllable double-acting piston-cylinder unit.
