Description

Description:

Device for filling shipping boxes Technical area:

The invention relates to devices for filling shipping boxes with bundles of printed products provided by a bundling machine, according to the preamble of claim 1. Prior art:

Printed matter, such as magazines, leaflets, flyers, etc., are bundled for shipment by package. This is done in so-called Kreuzlegern in conjunction with banding machines. Subsequently, the bundles are filled in layers in shipping boxes. The individual bundles can have very different formats; However, the formats are standardized, so it is possible to put the bundles together so that the base of the shipping box is well utilized. Once a shipping box is completely filled, it is sealed and shipped. Then a new shipping carton will be provided.

In order to make optimum use of the base area of the shipping cartons, the bundles belonging to a consignment must be inserted in a suitable manner. This means that some bundles have to be inserted longitudinally, others transversely, one layer may consist of one bundle, the next of several bundles of different format, etc. Due to the complexity of the layer formation, the filling of the shipping boxes is currently done by hand. That is unsatisfactory.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device by means of which it is possible to machine shipping cartons, ie. H. without the intervention of a human to fill optimally.

This object is achieved by a device having the features of claim 1.

CONFIRMATION COPY An essential element of the present invention is a grouper, ie the

Combination of device elements resulting from an incoming stream of

Bundles each forms a complete layer and several layers stacked on each other until the correct height for the respective shipping box is reached and the shipping box can be closed.

Thanks to the combination of lifting device, lifting stop device and stop, whose dimensions and position are matched to the bundle formats to be processed, with two slides, a swiveling platform and an extension, it is possible to fully automatically create a complete layer and also to position the layers fully automatically to stack.

According to one embodiment of the invention, the conveyor belt is divided into sections. In this way it is possible that the individual bundles start at the stops in the correct chronological order.

Advantageously, the platform has a pivot axis which is adjacent to the

Conveyor belt is mounted. In this way, the path that the bundles between

Cover conveyor belt and shipping carton, minimal.

According to one embodiment of the invention, the conveyor belt comprises parallel endless conveyor belts, the stops being positioned between the conveyor belts.

An important function also has the offshoot. He takes those on the platform

collapsed bundle layer on and gives it to the underlying lift from him by his two parts diverge synchronously, the bundle layer is delivered to the underneath lift.

Equally important is the function of the lift. This can be designed as a lifting fork according to an embodiment of the invention.

Advantageously, the lifting fork on a traverse and the traverse on

Leadership led. As soon as the lifting fork is filled, it will be down in the underneath

Shipping carton and then pulled out of the open front of the shipping box. In order to prevent the bundle layer from being pulled out as well, a retaining fork can be attached in front of the open front of the shipping carton.

Advantageously, the entire process is controlled and monitored by a control device.

Brief description of the drawings:

Reference to the drawing, the invention will be explained in more detail in the form of an embodiment. They each show purely schematically

1 is a plan view of a device for filling shipping boxes with bundles of printed products,

2 shows a side view of the device according to FIG. 1

Fig. 3 to Fig. 8 variants of the combination of bundles to a layer and

Fig. 9 is an illustration of the lifting and stopping devices that allow to form a layer of a bundle stream.

Ways to carry out the invention and commercial usability:

Fig. 1 as a plan view and Fig. 2 as a side view show an apparatus for filling shipping boxes 50 with bundles P1, P2, P3, P4, So of printed products, which were provided by a stacker in conjunction with a banding machine. Shown are only the elements important to the understanding of the invention. All other elements such as frame, drive motors, sensors, control devices, etc. are not shown here for the sake of clarity.

One recognizes a piece of a conveyor belt 1, which is divided into several sections in practice. The speed at which each section is driven can then be adjusted individually to ensure that the bundles arrive at the correct mutual distance.

On the conveyor belt 1 four bundles P1 ... P4 are shown with different dimensions by way of example. All bundles have the property that they can be assembled into a so-called layer with a base that fits a shipping box 50 (Fig.2).

The conveyor belt 1 are assigned one behind the other in the conveying direction

Lifting device 6 lifting stopped bundles, a lifting stop device 7 lifting or stopping incoming bundles, and a stopper 8 stopping incoming bundles. Some bundles, z. As the bundles P1 and P3 are stopped at the stop 8. So that they can be correctly deported from the slider 10, the platform 20 is pivoted to the position 20.2. Other bundles, eg. B. the bundles P2 and P4 are stopped at the lifting stop device 7. So that they can be correctly deported from the slider 10, the platform 20 is pivoted to the home position

The composition of a layer of the various bundles will be explained in more detail with reference to Figures 3 to 8. When a bundle is stopped, it is lifted to separate it from the conveyor belt 1. Then it is pushed by a slider 10 on a positioned next to the conveyor belt 1 platform 20. Then the next bundle is moved up and stopped. This is repeated until the platform 20 is filled. Once the platform 20 is sufficiently filled, it is pivoted about its attached next to the conveyor belt 1 pivot axis 22 by 90 °. Item 20.1 shows the platform in an intermediate position. Position 20.2 shows the platform in its end position. Here she is adjacent to an offshoot 30. Once the platform 20 has reached the offshoot 30, the bundles thereon are pushed by a second slider 21 on the offshoot 30. Thereafter, the bundle ply is deposited, the slider 21 retracts and the platform 20 pivots to the home position to receive the next bundles. Then the platform 20 can pick up the next bundles. Once a bundle is transported on the conveyor belt 1 whose dimensions are unsuitable for machine processing, all stops 7, 8 are deactivated so that this bundle is transported to a collection point (not shown) where the packing can be done by hand.

The offshoot 30 consists of two parts 30.1, 30.2, which can be moved apart synchronously and again together. Once a complete bundle layer is on the offshoot 30, the two parts 30.1, 30.2 are moved apart and the situation reaches an underlying lift 43 in the form of a lifting fork. This is guided on a crossbar 42. The Traverse 42 itself is in turn on guide posts 41 up and down mobile.

Once the desired amount of bundle plies is on the lift 43, it is lowered down to where the shipping carton 50 is with its front face open. Once there, the lifting fork is pulled forward. To prevent the bundles from being pulled out as well, it is in front of the open one

The lift 43 is then moved back up under the shelf 30 to receive the next bundle layers.

Once the shipping box 50 is completely filled, it is closed by means of a known and therefore not shown closure device and transported to the shipping. Then an empty shipping box is provided. Fig. 9 shows in an enlarged scale a perspective view of lifting device 6, lifting stop device 7 and stop 8. For lifting and lowering cylinders 6 ', 7' and 8 'are provided. Lifting device 6, lifting stop device 7 and stop 8 are slotted longitudinally. Through these slots run conveyor belt 9 of the conveyor belt 1. Figs. 3 to 8 show variants of the combination of bundles to a layer.

In Fig. 3 it can be seen how four layers P1 a layer is formed. Active is the stop 8, at the first two bundles P1 stopped and together on the

pivoted platform 20.2 be deported. The next two bundles will be P1 also stopped at stop 8 and deported together. They push the already existing bundles into the final position. Now the slider 21 can push the position on the offshoot 30.

FIG. 4 shows how four layers P2 form a layer. Active is the lifting stop device 7, stopped at the first two bundles P2 and deported together on the platform 20. The next two bundles P2 are also stopped at the lifting stop device 7 and deported together. They push the already existing bundles into the final position. Subsequently, the platform 20 is pivoted to the position 20.2. Now the slider 21 can push the position on the offshoot 30.

In Fig. 5 it can be seen how a bundle P3 comes to the offshoot 30. Active is the

Stop 8, platform 20 is in position 20.2. Once the slider 10 has the bundle P3 deported to the platform 20.2, it can be deported from the slider 21 to the offshoot 30.

In Fig. 6 it can be seen how a bundle P4 comes to the offshoot 30. Active is the lifting stop device 7, at which the bundle P4 is stopped, to then be pushed onto the platform 20. Subsequently, the platform 20 is pivoted to the position 20.2. Now the slider 21 can push the position on the offshoot 30.

FIG. 7 shows how a layer is formed from three bundles So1 with a non-standard special variable. Active is the lifting stop device 7, at the first a bunch So1 stopped and deported to the platform 20. Subsequently, the platform 20 is pivoted to the position 20.2. Now the stop 8 is activated, stopped on the two bundles So1 and together on the pivoted platform 20.2

be deported, taking the bundle already there in the

Slide end position. Now, the slider 21, the position on the offshoot 30th

deport.

FIG. 8 shows how a layer is formed from three bundles So2 with a non-standard special variable. Active is first the lifting stop device 7, at the succession two bundles So2 stopped and deported to the platform 20. Subsequently, the platform 20 is pivoted to the position 20.2. Now the Stop 8 is activated at which the third bundle So2 is stopped. The slider 10 pushes the third bundle onto the pivoted platform 20.2, pushing the bundles already there into the end position. Now the slider 21 can push the position on the offshoot 30.
