Gripping device for bottles or similar objects

Field of application of the invention

The invention relates to a gripping device for packing and unpacking of articles, inabesondere bottles. The gripper can be used both as individual elements as well as in association, for. For example, packing heads are used.

Characteristic of the known technical solutions

There are packing and unpacking machines for bottles are known in which the gripping device is pneumatically driven «, This must be applied during the entire transport energy to maintain a pressure or, vacuum. Known mechanical gripper consist of a gripping bell or gripper fingers, which are pressed against the spring pressure of the article when placing the device on the object. By a locking device this position is fixed. For special elements outside the gripper are arranged, which are also driven separately.

In 03 1111501 a plate with specially shaped through holes is used for this purpose, which extends over the entire gripper. For locking and unlocking a special drive is required. These additional ^{Δ Ί} entente require not only power and a longer j ^J rozeßablauf. The pressing together of the gripping bell takes place by means of force by means of a slanted plane, which causes not only high wear but also large force introduction,

Object of the invention

The aim of the invention is ea, to reduce the consumption of energy, to allow short switching times and easy replacement of individual grippers »

Essence of the invention

The object of the invention is to reduce in mechanical grippers for the gripping of ^ 'tabs and the locking of the gripper forces required and no auxiliary drives to use.

According to the invention the object is achieved, depending on a locking device with a gripping device as a self-acting. Unit is formed. Preferably, the locking device consists of two opposite switching crowns with a crown profile for ·. switching stages and an intermediate switching unit. Each lowering of the gripper head is a switching operation and the gripper is fixed or released in its position.

The gripping device consists of unilaterally mounted clamping levers which are pressed together by a compression spring on the outer circumference «,

The training allows small holding or spring forces. The lifting movement can additionally drive the locking device. Both modules form an autonomous unit that is easy to replace and has short switching times

embodiment

In the following, the invention will be explained by way of example.

Figure 1 shows the locking device and the gripper in side view in the open state

Figure 2 shows the same view with the gripper in the closed state and locked «

The entire system lowers, powered by an electric motor-gear unit, over the provided full or empty bottle. The stamp 001, provided with a centering 017, sits on the bottle head.

With the placement of the punch 001 at the same time the movement of all 'associated with him rigid elements is interrupted. These are the axis 003, the switching crown OO4, the connecting element 005, the guide cylinder 006, the spacer pin 007 and the locking plate 008, the drive unit now pushes the cover plate 016 relative to the locking plate 008 down. The same movement carry out all the elements associated with the cover plate 016. These are the piston 015, the shift rod OH, the switching unit 013, the compression spring 012, the outer cylinder 011, the connecting spokes 010 and the hub 009. The spring 012 presses on the clamping lever 002 and presses against the bottle neck, to a relatively safe and at the same time to ensure elastic gripping, the fog ^ 002 are on the terminal points of rubber or plastic _o elements 019 provided. During this movement phase sets switching unit 013, coming from the top layer Ά, on the inclined tracks of the switching 004. The unit 013 Fühifc according to the path inclination from a rotational movement until it encounters the position C against a stop of the switching crown OO4. Now the cover plate

016 moved back in the opposite direction and thus all the above moving parts. However, there is only a very small return movement, since the switching unit 013 is locked by the FUhrungszylinder 006 in the B position. In this case, the unit 013 undergoes a certain rotation β from C to B through the design of the PührZylinders 006

By this low jerk stroke of all moving parts, it is ensured that the compression spring 012 is still under tension and press the clamping lever 002 with sufficient force against the bottleneck. Further lifting of the cover plate 016 causes the entire system, including the full or empty bottle detected by the ^ri ebel 002, to follow this lifting movement by the locking of the unit 013. (018 - backrest spring for clamping lever 002)

The settling and releasing the moving bottles takes place in principle opposite order;

After placing the full or empty bottle (in the bottle crate or on a Tran3port table), the main drive pushes the cover plate 016 and thus all related moving parts down. In doing so, I lower the switching unit 013 from the position B and set on the inclined surfaces of the switching crown 004 on. As a result of the acting compressive force, the unit 013 makes a rotational movement on the tracks of the shift crown 004 until it is stopped by corresponding stops.

During the subsequent return movement (lifting) of the movable elements, the unit 013, guided by the guide cylinder 006, returns to the starting position A. The compression spring 012 relaxes completely and is lifted off the clamping levers 002. By means of small return springs 018 the levers 002 move into their starting position and release the bottle. The return movement of the movable

Finally, elements causes the piston 015 abuts against the locking plate 008 and these are raised with da Da on the locking plate 008 all rigid elements ** are connected, now lifts the entire gripper mechanism of the bottle and releases it for the following transport process.
