Device for bending and fastening the edges of a container for agricultural use Products

The invention relates to a device for bending and fastening the sides of a container for fruit or vegetables through Gluing.

Increasingly, containers for fruit or vegetables are made of cardboard in the trade used, which are delivered to the packaging company as blanks, so that they only require a very small amount of space; so they then have to be folded and shaped by the packer when the fruit and vegetable harvest is delivered. It However, it is necessary that such containers for fruit and vegetables be completed in large numbers and in a very short time

will. So this flat container must be folded or glued a considerable number of man-hours are used, which is very costly, so that it is practically possible to that the production costs for the individual container are doubled.

The invention is now based on the object of remedying this disadvantage by creating a machine with which it is possible to bend up the sides of the flat fruit or vegetable container after gluing and in this To hold position, these containers have transverse edges that are folded horizontally and reinforced Form ends so that a fan-shaped deformation of the flat container is possible without the risk that they are pressed together and hooked into one another.

If one can easily imagine the design of a machine with which it is possible to produce a flat container for To fold fruit with four vertical sides and to fix it in its shape by gluing, this does not apply to the The flat containers described above with reinforced transverse edges. The parts that form the inner forms with which the parts forming the vertical and horizontal transverse edges must actually be pressed again Can be pulled out if the flat container is completely is completed so that it is released and transported to the filling station for the fruit or vegetables can be.

This object is achieved according to the invention with a device solved the type mentioned in that it consists of a vertically movable table, which on his

upper section carries articulated arms, at the ends of which blocks or forms are attached that serve as a support for the various vertical and horizontal sides of a Flachbehäiters for fruit and vegetables when they are produced under pressure between the blocks, and that they furthermore consists of a frame which lies above the table and is articulated in a suitable manner.

According to a further feature of the invention is the inner

Part of the blocks beveled.

Various further features of the invention emerge from the following description of an exemplary embodiment the same with reference to the accompanying drawing.

Fig. 1 shows a preformed and pre-cut blank or blank for a flat container for fruit in Shape of the rectangular part 1, like it from the cardboard box factory to the packaging company in the unfolded condition is delivered. This blank is combined with many other identical blanks into one - mostly vertical - Inserted feed mechanism, to which a pneumatic gripping device 3 connects, which each blank detected individually and this feeds a glue station. Then by appropriately shaped guides 2,3 ensured that the lateral vertical parts of the blank are closed in such a way that they open a part 4 with two inner shapes come to rest.

Each element 4 consists of a lifting table 5, the vertical guide of which consists of organs 6, while the lifting or Lowering movement is brought about by the winches 6a.

The lifting table 5 carries on its upper one. Section a support 7, the opposite ends 8, 9 of which are equipped with bearings iO, in which axes can rotate which are fixed to arms 11 which carry the blocks forming the molds 12; the lower portion of the molds 12a is substantially at an angle of 20 abgeschrägtDie arms 11 rest on supports 13 _S which are integral with the upper surface of the lifting table. 5 From FIG. 4 it can be seen that the lifting table is surmounted at point 16 by a protruding frame 14 which is provided to facilitate the closing of the side and longitudinal edges of each blank, which is then intended to represent a flat container. The frame 14 consists of parts that can first be set vertically and then horizontally by being able to pivot along the axes 15.

are arranged, which are provided for this purpose on the machine frame, not shown. The machine according to the invention now works as follows:

The blank 1, the edges of which were glued accordingly, arrives at the top of the lift table 5. At this moment the blocks 12 are in a horizontal position, there the arms II rest on the supports 13. Once the cut is correctly positioned, the lifting table 5 is raised in the direction of arrow F. (Fig. 4) and through this Movement is brought about the pivoting movement of the longitudinal and transverse sides of the blank 1, with these edges be folded up into a vertical position, being between the parts of the frame 14 on the one hand and the blocks 12 on the other hand be wedged. As soon as the table 5 has reached its raised position (FIG. 5), the Parts of the frame 14 folded over and arranged horizontally with a corresponding control effect; from this moment on the transverse parts of the blank, which form the horizontal sections 101, 102 (see FIG. 7), rest on the transverse parts of the frame 14 and are thus also glued. This work is then ended by the fact that the Support table 5 on its way down (see. Fig. 6) in the direction of arrow F_ by means of the inclined edges 12a of Blocks 12 generated a pressure, whereby a correct gluing of the parts 101, 102 by pressure on the corresponding Dividing the frame 14 is ensured. At a certain moment, the blocks 12 slide out of the Interior of the flat container 1 (see. Fig. 6). As soon as the table 5 has reached its starting position again, can the flat container for fruit or vegetables produced in this way (see FIG. 7) can be moved manually or automatically

remove, the parts of the frame 14 being returned to their original position; then a new glued blank placed on top of the device described above. This machine is very simple built and their production costs are very cheap. In addition, it is completely safe and required no additional safety devices. It can thus be used in a simple manner and results in a careful quick work.

Even if the invention is described on the basis of a * - benen Ausführungsbexspieles was explained, so it is by no means limited to this, but it is Various changes and codifications are possible within the scope of the invention.

In summary, the invention relates to a device with which the edges of a flat container with Fold the horizontal sides to hold fruit, vegetables and other products and fix them with glue permit.

It consists essentially of a vertically movable table 5, the arms articulated on its upper portion 11 carries, at the ends of blocks or, forms 12 are attached, which serve as a support for the various vertical and horizontal edges of a flat fruit and vegetable container are used during its manufacture, the container itself by pressure between the aforementioned blocks 12 and a correspondingly articulated and arranged above the table 5 Frame 14, 16 is completed.

This device can be used for different packaging of different products.
