Definitions
- the invention relates to a device for erecting flat folding box blanks or the like, with a lower mold and a stamp, the walls of the folding box blank arranged between the stamp and the lower mold being folded up when the mold is immersed, as well as the stamp and the lower mold when folded up of the walls are moved synchronously in the conveying direction of the folding box blanks.
- Such a device for erecting flat folding box blanks or the like is known from DE 43 22 224 C2.
- This has an approximately U-shaped lower mold, which is fastened to a transport chain, and an upper mold plunging into the lower mold, which is fastened to an upper transport chain.
- the lower mold and the stamp are moved synchronously in the direction of transport, whereby the stamp dips into the lower mold and the walls of the folding box are folded up.
- the transport chain for the form stamp is longer than that for the lower mold and a transport belt connects to the transport chain of the lower mold.
- the device for erecting Folding boxes have, in particular, a multiplicity of shaped dies or sub-forms connected to the respective transport chain.
- a disadvantage of the known device for erecting the flat folding box blanks is the arrangement of the stamps and the lower molds on circulating transport chains.
- a large transport length is therefore required, within which the plunging movement of the stamp takes place in the assigned lower mold.
- special guide elements for the shaping stamp and the lower molds are required.
- the large length means high construction costs of the device. Since it is necessary for economic reasons to equip the device with a large number of stamps and sub-molds, the conversion of the device to other folding box formats is associated with a considerable amount of time and work.
- the object of the invention is to develop a device of the type mentioned at the outset in such a way that it is structurally very simple and can be produced inexpensively, and further that it can be converted in a short time.
- This object is achieved in a device of the type mentioned at the outset in that the shaping die and the lower mold are each mounted in a crank mechanism, the cranks of the crank mechanisms being driven in opposite directions in the direction of rotation.
- the invention thus frees itself from the principles of operation of the devices described for erecting flat folding box blanks and, instead of a stamp which is attached to the transport chain and which rotates with the transport chain, which is in a lower mold, which in turn is fastened with a circulating transport chain, a mold stamp and a lower mold before, which are each mounted in a crank mechanism, the cranks of the crank mechanisms being driven in opposite directions in the direction of rotation.
- the operating principle of the crank mechanism means that when the crank mechanisms pivot, the form punch and the lower mold both perform a movement towards and away from one another as well as a movement with a movement component in the conveying direction of the folding box blanks.
- the form punch or the lower mold executes the movement sections which lead to the immersion of the form punch in the lower form, the further transport in the conveying direction and the extension of the form punch from the lower form. Consequently, with this operating principle, the folding box blank is deformed in the sense of the erection of the folding box and at the same time the folding box blank or the erected folding box is transported further in the conveying direction, so that a continuous erection of folding boxes which are fed in the conveying direction of the device according to the invention is ensured.
- the particular advantage of the device according to the invention can be seen in the fact that it manages with a single die and a single sub-mold. As a result, the device can be made very compact and it is only necessary to change over to other folding box formats to set up the single form stamp and the only lower mold. This is the great advantage of the device according to the invention over the prior art discussed.
- a particularly advantageous development of the invention is characterized in that it has a rotating transport unit for transporting the folding box blanks to the device and the erected folding box away from it.
- the respective folding box blank therefore does not have to be placed on the lower mold, but the folding of the folding box blank takes place by means of the rotating transport unit to the pre Direction for erecting the folding box blanks.
- a very big advantage can be seen in the fact that only a single rotating transport unit is required. This thus serves both to promote the folding of the carton blanks to the erecting device and to remove the erected carton. If the folding box blanks rest during transport to the erecting device, for example on guide rails, the folding or folding of the folding box blanks is advantageously carried out by means of carriers.
- the transport unit is provided with the drivers for the folding box blanks or erected folding boxes, in particular with the drivers placed directly behind them.
- the strips on which the folding box blanks or the erected folding boxes lie are preferably guide strips for circumferential chains to which the drivers are attached. So that the folding box blanks or erected folding boxes can be transported precisely, several strips with chains and carriers arranged parallel to each other should be provided. If possible, the blanks or erected folding boxes should be supported over a large part of their width, in particular lying on the strips.
- side guides can be provided, which in particular guide the folding box blanks laterally, since it is essential in the device according to the invention that the folding box blanks are fed to the working area of the punch and the lower mold with dimensional accuracy.
- the transport unit passes through the area of the device for erecting the flat folding box blanks.
- the transport unit is thus not interrupted and the transport unit is not stopped when the device according to the invention is active, thus erecting the respective folding box.
- This can be accomplished, for example, in that the lower mold is of divided design and the transport unit is carried out between the parts of the lower mold.
- the lower mold is expedient, essentially U-shaped in a projection transverse to the conveying direction of the folding box blanks / erected folding boxes.
- the U-shaped parts of the lower mold ensure that the bottom of the box and the walls of the box form a defined counter surface when the box is erected.
- the development of the invention thus dispenses with the formation of a box-shaped or similar lower mold, but only requires that Edge areas that are necessary for the storage and reshaping of the individual sections of the respective folding box blank when the lower mold and the die stamp interact.
- the strips receiving the bottom section of the blank are also carried out between the parts of the lower mold.
- the transport level of the strips receiving the blank and the transport unit should be placed higher than the lowest level of the upper end of the lower mold and lower than the highest level of the upper end of the lower mold. This means that the lower mold only contacts and lifts the folded carton blank conveyed into its area when it is raised from its lowest position, and that the folding box is then erected by raising the lower mold with its upper end above the transport level of the transport unit, during which time the lowering die dipped into the lower mold. It is essential that the transport level of the transport unit or the strips is placed lower than the lowest level of the lower end of the stamp. This ensures that the stamp cannot contact the transport unit or the strips.
- the stamp and the lower mold are controlled in such a way that they are arranged vertically during the entire rotation of the crank drives. Imagined vertical axes through the stamp and the lower mold are therefore basically parallel. This sequence of movements is realized in a particularly simple manner by the respective crank mechanism being designed as a double rocker.
- the deformation work for erecting the respective folding box is thus performed only over a certain pivoting range of the respective crank drive.
- the folding of the folding box blank takes place in particular via a crank angle of the respective crank mechanism of 50 to 70 °.
- the pre-stroke of the folding box blank by means of the lower mold before the interaction of lower mold and punch takes place in particular via a crank angle of the crank mechanism assigned to the lower mold of 20 to 40 °. It is essential that the movements of the stamp, bottom mold and transport unit are synchronized. If the folding box blanks are placed on the transport unit by means of a rotary depository, the movement of the rotary depository should also be exactly coordinated with respect to the movements of the die and the lower mold as well as the transport unit.
- servo drives are particularly advantageous because, due to the crank geometry, the folding box blank is lifted off the transport unit along a curve and thereby comes out of contact with the previously assigned driver, which is therefore preferably tracked.
- the punch has one or more suction elements on its underside, in particular pneumatically active suction elements. The raised folding box blank is therefore fixed by means of the die before erection.
- the folding box After the folding box has been erected, it must be ensured that it detaches from the form stamp as soon as it is moved out of the lower mold. This is guaranteed by the fact that the stamp is provided on its underside with one or more ejectors, in particular with mechanically effective ejectors. Due to the mechanical actuation of the ejectors by means of mechanical components of the crank mechanism, the erected folding box can be detached from the forming die immediately when the forming die and lower die move apart or when the forming die emerges from the underforming die, so that it underneath during the downward movement of the upper end of the lower die the level of the transport unit is placed gently on the transport unit, so it does not fall on it. This is an essential prerequisite for the erected folding box to be transported precisely.
- the transport unit and / or lateral guides of the folding box blank or the erected folding box should be adjustable in width.
- the folding box blank used in the device according to the invention has broken in particular in the area of the folded edges.
- the lower mold is additionally provided with baffles in order to be able to deform the cut in a simple manner.
