Technical Field
[0001] The present invention relates to a triple drive system which is integrated on existing cutting machines used for cutting printed packaging papers.
[0002] In particular, the invention relates to three times more product cutting in the same work time by assembling the triple drive system, instead of the single drive, to the product feed and cutting parts for the printed packaging papers.
Prior Art
[0003] In the prior art, different types of cutting machines are used for cutting the printed packaging papers. A single drive system is used for cutting in existing cutting machines. Printed packaging paper passes through a single cylinder of the drive system and proceeds towards the blades and the cutting is thereby performed. As a single drive system is used in existing cutting machines, cutting speed is reduced and mass production capacity is reduced.
[0004] In the patent search, a system similar to the subject invention was not found. However, some patents made in the same field of art are described below.
[0005] European Patent No. EP2543504B1 relates to a device for processing packaging material for cigarette packets, which comprises a feed line for the packaging material, the latter having a longitudinal edge which is substantially parallel with the feed line, and also comprises a first cutting device comprising at least one cutter profile extending along a main longitudinal line) which is substantially parallel with the feed line; at a first operating station and with the packaging material stationary, the first cutting device brings its cutting profile into contact with the edge of the packaging material in a position such that the main longitudinal line of the selfsame profile lies, at the moment of cutting, in a plane which is substantially coplanar with the plane in which the packaging material lies so that the entire notch is made immediately and all at once.
[0006] Another document EP2537766B1 can be indicated as an example found in the literature search. The said invention relates to a completely cutting station and separating the packagings. It is related to completely cutting station to be separated cutting packages from a film composite by means of a movable, configured for severing the film composite completely cutting tool. The completely cutting station further comprises a transport system comprising a plurality of transport elements for transporting a respective one includes singulated package, wherein each transport member has a head portion for engaging the respective packing. The invention is characterized by the fact that the head portions of at least some transport elements are movable defined between a first position in which detected them packaging a through the film composite first distance from one another, and a second position, in of the packaging a second, smaller distance from one another or overlap at least in one direction in space at least partially.
[0007] Consequently, the existence of the above problems and the insufficiency of existing solutions necessitated an improvement in the relevant technical field.
Objects of the Invention
[0008] Based on the state of the art, the main object of the invention is to develop a triple drive system for printing printed wrapping paper, where disadvantages in the prior art are eliminated and thus the advantages are brought.
[0009] Another object of the invention is to provide three times more product cutting in the same work time by assembling the triple drive system instead of the single drive to the product feed and cutting parts for printed packaging papers.
[0010] Another object of the invention is to automatically control the entry of the packaging papers into the system, their movement within the system and all the parameters during their exiting from the system (desired distance, suitable cutting position, movement speed, etc.) according to the signals from the sensors and encoders via a control unit.

Detailed Description of the Invention
[0013] This invention relates to a triple drive system (A) which is integrated on the existing cutting machines used for cutting the printed packaging papers.
[0014] Figure 1 shows a general perspective view of the triple drive system (A) according to the invention.
[0015] The printed packaging paper moving on an existing machine enters a first edge control system (1). The first edge control system (1) ensures that the printed packaging paper enters the system properly and continues to be aligned in the system. The first edge control system (1) ensures that the product moves stably on the cylinders and enters the blades in the same position.
[0016] The printed packaging paper exits the first edge control system (1) and enters the first drive cylinder (4). During this transition, the product passes against a first encoder (2) and a first sensor (3). In this way, the position information of the product is obtained. The first drive cylinder (4) enables the product to be driven towards the blades in a distanced manner (the desired distance or the appropriate cutting position). The first drive cylinder (4), which performs the paper driving, manages the driving distance according to the information from the control unit. The control unit determines the current position of the paper according to the information from the first encoder (2) and the first sensor (3). The current position is interpreted in the PLC control unit and the driving distance is transferred to the motors each time in such a way that the printing on the product and the blades are aligned.
[0017] The motors rotate the first drive cylinder (4) at the same rate. The first drive cylinder (4) also feeds the product at the same rate in front of the blades. In this way, the stable cutting process is repeated continuously.
[0018] The printed packaging paper exits the second edge control system (5) and enters the second drive cylinder (8). The product passes through a second encoder (6) and a second sensor (7) during this transition. In this way, the position information of the product is obtained. The second drive cylinder (8) allows the product to be driven towards the blades in a distanced manner (the desired distance or the appropriate cutting position). The second drive cylinder (8), which performs the paper driving, manages the driving distance according to the information from the control unit.
[0019] Similarly, printed packaging paper exits the third edge control system (9) and enters the third drive cylinder (12). The product passes through a third encoder (10) and a third sensor (11) during this transition. In this way, the position information of the product is obtained. The third drive cylinder (12) allows the product to be driven towards the blades in a distanced manner (the desired distance or the appropriate cutting position). The third drive cylinder (12), which performs the paper driving, manages the driving distance according to the information from the control unit.
[0020] Also, the PLC control unit adjusts the positions of the products in the second drive cylinder (8) and the third drive cylinder (12) with respect to the position of the product in the first drive cylinder (4) and thereby align the products so that the printing patterns overlap one another. Thus, three layers of product can be cut with one blade unit at the same time. After the blade cutting, the products were obtained as being cut and prepared for use.
