Description

The invention relates to a device for producing finished articles, such as containers or shells made of a band-shaped material.

Usually, finished articles, for example in the form of food packaging trays, are produced with the aid of presses operated by crankshaft drives. In this case, self-contained units, such as an unwinding unit for supplying a band-shaped material; a press unit for pressing the finished articles from the strip-shaped material and a stacking unit for collecting and stacking the manufactured finished articles along a production line placed one behind the other. For example, the band-shaped material is made of aluminum.

In the EP 2274159 B1 such a device is described. In essence, this device comprises a feed unit, in which the band-shaped material is unwound from a spool. The unwound strip-shaped material is subsequently supplied stepwise to a pressing unit, in which it is passed between an upper molding and a lower molding. The upper mold part and the lower mold part, when pressed against each other, form therebetween a cavity which corresponds in terms of its shape and size to the finished article to be produced. During the pressing process, the upper mold part is moved with the aid of a threaded mechanism operated by an electric motor in the direction of the stationary lower molded part. The pressed finished articles are then removed from the press unit by a removal device and subsequently fed to a stacking unit and stacked. The feed unit, the pressing unit, the removal device and the stacking unit are arranged as separate units along a production line in the order named in the longitudinal direction one behind the other.

The object of the present invention is to improve a known device of the aforementioned type so that it is relatively easy and inexpensive to handle.

To solve this problem, the device according to the invention comprises a feed region, a pressing region and a stack region, which are arranged next to one another in a common frame in the longitudinal direction. In the feed region, a winding of the band-shaped material in the frame is rotatably storable, wherein preferably mounted on an arm Abwickelrad on the surface of the roll can be arranged and driven by a drive to set the winding in rotation and tape-shaped material from the winding handle. The arm part is rotatably mounted in the frame about a pivot point spaced from the drive. The unwound from the winding material is fed to the gap between two arranged in the frame conveyor rollers and these directly to the pressing area. The pressing region comprises a first shape-retaining part movably arranged in the frame and a second shape-retaining part fixedly mounted in the frame, which are movable toward one another into a closing position and away from one another into a release position by a drive. The unwound strip-like material is moved by the conveyor rollers directly between molded parts for producing and releasing the finished article mounted on the mold holding parts, wherein the mold parts are successively moved between the closing and the releasing position. The manufactured finished articles are successively moved from the pressing area directly into the stacking area and stacked in this.

The essential advantage of the present invention is that the present device for producing finished articles from a strip-shaped material is formed as a compact unit, which has an unwinding area, in which the strip-shaped material is unwound from a reel, a press area in which the finished articles are pressed from the band-shaped material and comprises a stacking area, in which the finished articles produced successively in the pressing area are stacked. It is essential that the said areas are arranged in a common housing or frame immediately next to each other and are combined functionally and constructively to a narrow or small-sized, compact unit.

Advantageously, the fact that the unwinding area, the pressing area and the stacking area are arranged as a compact unit in a common frame substantially reduces the production costs of the device according to the invention.

Since the present invention is formed as a compact unit having a relatively small footprint, installation of the equipment in a factory floor or the like requires a much smaller area than the conventional apparatuses. This leads to significant cost savings.

Since the present unit has a relatively low weight, it can be relatively easily moved and transported inexpensively. A faster air transport compared to a ship transport is therefore also possible.

Another significant advantage of the present invention is that the present compact device for pressing finished articles can be easily controlled by a single operator, whereas in the above-described, known device in which stand-alone units for unwinding, pressing and stacking are arranged side by side along a production line, several Operator are required.

Because the unwinding wheel arranged on an arm part is arranged above the reel, a particularly space-saving arrangement of the individual parts (reel, arm part, unwinding wheel, drive, conveying rollers) of the unwinding area results in the longitudinal and transverse direction as well as in the height of the present device.

Advantageously, in a further development of the invention, the winding is arranged on a spool, the shaft of which is mounted in receiving parts which are opposite one another in the transverse direction and which are arranged on opposite regions of the frame. If necessary, therefore, different coils with different band-shaped materials for the production of different finished articles can be replaced quickly and easily.

In an advantageous development of the invention, the finished articles produced in the pressing area are successively fed to the stack area and stacked on a conveyor table arranged in the frame. Preferably, the conveyor table is designed to be height adjustable. Its position can therefore be adapted during the stacking process to the respective stacking height of the finished article.

The waste material arising from the web-shaped material during pressing is conveyed advantageously via a guide shaft into a waste collection container which is arranged in the stacking area below the conveyor table, wherein the guide shaft is formed in the frame between the pressing region and the stacking region and therefore occupies little space. In this way, the waste produced during pressing is ready for quick and easy disposal. In an advantageous embodiment of the invention, the guide shaft comprises a first leg region extending from the pressing region and a second leg region, which are connected to one another in a corner region, the first leg region starting from the pressing region and the second leg region ending above the waste collecting container. In the corner region, a nozzle arrangement is arranged such that it sucks the waste produced during pressing from the pressing area into the first leg area to the corner area and pushes it out of the corner area into the second leg area. In this way, a particularly rapid and effective transport of the waste from the pressing area to the waste container is achieved - integrated into the frame.

In order to make the present device particularly compact, the electronics for controlling the device in the frame, preferably arranged on a panel mounted in the frame under the pressing area panel.

Particularly advantageous, simple, lightweight and compact is in the pressing region of the device according to the invention, the upper mold holding part attached to each transversely opposite side of the frame on opposite sides of two spaced apart longitudinally spaced, parallel drive belt, the drive belts each between two pulleys, which are seen in the direction of movement of the upper mold holding member rotatably mounted one above the other in the frame or arranged and wherein the drive belt can be driven by at least one arranged on the frame drive motor. Particularly preferably, the respectively opposite in the transverse direction pulleys are arranged on a common, mounted in the frame shaft, wherein in each case a shaft of a belt pair is driven by a drive motor.
