Abstract

PURPOSE: To obtain a compact device having a small required space by forming a forming stamper as a cylinder opened to both upper and lower sides, and a filling pipe for filling a filler arranged continuously to the cylinder. CONSTITUTION: A flat cutout piece 2 provided with the bottom, the foldable side faces, and sticking pieces is supplied to a main device by a conveyor and accurately positioned and lowered on a set-up frame 5. A forming stamper 4 made of a cylinder 9 is inserted in the set-up frame 5. In this case, the side faces of the cutout piece 2 are set out. These side faces are brought into contact with the cylinder 9 in accordance with the advance of a pressing stamper 6 and further, mutually bonded by adhesive pieces bent at the same time. A filler 10 is charged into the cylinder 9 mounted on the bottom of the cutout piece 2 through a filling pipe 8 during the forming process. The folding box 1 is held by the pressing stamper 6 brought into contact with the side faces during the filling process. After the forming and filling processes, the pressing stamper 6 is returned to the initial position and the folding box 1 is lowered on a conveyor 13 arranged right thereunder if possible.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is provided with a set amplifier section having a horizontal seven-node amplifier frame and a hollow molded stamper that can move up and down. fitted to the bottom of the strip, and provided with a filling of the material to be packaged, in which the molded stamper is insertable into the set-up frame, and when the molded stamper is inserted into the set-up frame; Cenote Asopfre
A folding box consisting of flat shreds with a bottom, foldable sides and adhesive strips is set up with the sides of the shreds resting on a box and at the same time connected to each other by folded adhesive strips. Relating to equipment for setting up and filling.

Paper cut pieces are mainly used as cut pieces.

If high requirements are placed on the parallelism of the sides, the device may additionally have stampers arranged under the set-up frame, these stampers being movable towards the forming stamper. It's advantageous. If the filling is heavy, a counter-stamper is additionally used which acts from below towards the bottom of the folding box.

BACKGROUND OF THE INVENTION In a device of the type mentioned at the beginning, known from DE 15 86 034 A1, the upper side of the molding stamper is closed. The material to be packaged is inserted into the forming stamper through the side insertion openings and placed on the bottom of the flat strip. The forming stamper then moves downwards, and the folding box is set up. The known devices are only suitable for individual fillings. Furthermore, it is disadvantageous that the set amplifier process can only be started once the filling process has been completed. This limits the achievable device cycle speed.

For the packaging of droppable fillings and small granules (e.g. screws, sticks, candies), devices are used in which a set-up section and a filling section are arranged one after the other in the production line (German Patent Application No. 2060952) No. Specification).

Both parts have a positioning device for the cut pieces or folded sections and are connected to one another by means of a conveying device. Such devices require a large amount of space and are expensive in construction and control technology.

OBJECTS OF THE INVENTION The object of the invention is to process individual objects (e.g. bags) and droppable fillings and small particles (e.g. screws, nails, candies).
The aim is to improve the equipment mentioned at the outset so that it can be packaged at high cycle speeds.

Structure of the Invention In order to solve this problem, the present invention shows the following. That is, the molding stamper is formed as a cylinder that is open on both upper and lower sides, and a filling pipe for supplying the filling material continues to this cylinder.

The invention is based on the idea of structurally and functionally integrating the set-up part and the filling part.

The production time for setting and gluing the sides of the cut pieces is also used for filling the folding boxes.

The molded stamper, which is designed as a cylinder, then plays a dual role. This molding stamper serves as a support for the molding process during the production of folding boxes. At the same time, this tube-shaped stamper forms a receiving volume for the filling that has entered through the filling tube. In this case, it is also possible in particular to carry out filling with droppable fillings.

The tightness between the bottom of the folding box and the cylinder placed on this bottom is sufficient to prevent the spillable filling from escaping. Considerable advantages result from the inventive integration of the amplifier section and the fill section.

For example, it is only necessary to position the cut pieces in the centamp frame once. Synchronization of work progress, especially between sex-up and filling, can be done easily.

Since a buffer device between the set-up section and the filling section is omitted, a very compact device with an overall small space requirement is obtained.

It is essential to configure the filling tube and tube as one integral part, or to use a flexible filling tube that is fixedly connected to the tube and follows the reciprocating movement of the tube. It falls within the scope of the right of invention. It is advantageous to use a vertically arranged rigid filling tube, which is arranged movably within the cylinder. It is advantageous if the cylinder is inserted into a stamper plate that can be moved up and down. If the tube has a double jacket with an evacuable jacket space open to the folding box side,
The seal between the bottom of the folding box and the cylinder resting on this bottom can be further improved. It is clear that the well-known burping gas absorption systems can likewise be inserted into the filling tube.

Example Embodiments of the present invention will be described in detail below with reference to the drawings.

The illustrated device is used for centrifuging and filling folding boxes consisting of flat shreds 2. The device is suitable for individual and drippable fillings. The shredded pieces generally refer to shredded cardboard pieces. In its basic configuration, the device includes a set-up section 3 having a forming stamper 4 movable up and down, a horizontal set-up frame 5, a stamper 6 disposed under the stamper frame 5, and a filling material to be packaged. A filling section 7 having a filling tube 8 is included. As can be seen from the figures with respect to the movement sequence, the forming stamper 4 can be inserted into the set-up frame 5 and, when pressed, the stamper 6 can be moved towards the forming stamper 4 .

As can be seen in particular from FIG. 2, the molding stamper 4 is designed as a cylinder 9 open on both sides and having a cross section adapted to the bottom of the cut piece 2. A filling pipe 8 for supplying a filling material 10 is connected to the cylinder 9.

The filling tube 8 is designed as a vertical stand pipe and is movably arranged in the tube 9. The filling tube 8 has a hopper-like enlarged portion 11 on the inlet side.

The cylinder 9 is inserted into a stamper plate 12 that can move up and down.

The operation of the device will be clear from a comparative consideration of FIGS. 1 and 2. The flat cut pieces with a bottom, bendable sides and adhesive strips are fed to the device by means of a conveying device, not shown in detail, and are precisely positioned and lowered onto a set-up frame 5 in a known manner. It will be done. The molding stamper 4 formed from a tube 9 is inserted into a set-up frame 5, in which case the sides of the cut pieces 2 are set up. In pressing, these side surfaces are brought into contact with the tube 9 by the advance of the stamper 6, and are simultaneously bonded to each other by the bent adhesive pieces. During the forming process, the filling 10 is inserted through the filling tube 8 into the cylinder 9 which rests on the bottom of the cut piece 2 . During the filling process, the folding box 1 is held by the stamper 6 against the side pressure. After the shaping and filling process has been completed, the stamper 6 is returned to its initial position and the folding box 1 is lowered onto the transport device 13, which is preferably located directly below it.

The stamper located under the set-up frame may be omitted if this is only necessary for a particular box construction and no special requirements are placed on the parallelism of the sides. There is otherwise no change in the operation of the device.
