Background of the Invention

Today, there is a protective stretch on the coil used as raw material in classical chart manufacturing process. The protective stretch on the coil used during production is sized as a coil layer by peeling off. Printing and cutting cannot be performed because there is a rotation problem in the last remained 50-60 meters of the coil products as a result of sizing.
In the chart printing machines used in the present technique, printing is carried out by offset printing technique. After printing process, cutting process is performed in a separate machine with a sheet blade. The lifetime of sheet blade used in cutting process is 70-80 thousand charts even under the best conditions and then it blunts, thereby causes additional blade cost.
In the known art, cut products are sorted out by manpower. During sorting out, cutting precision of the cutting machine is not regular. Therefore, the sorted products can drift away or are not separated from the cut; this causes large amounts of wastage. The bores of the sorted products are dropped and pin holes are opened, then color chart is formed by blending technique. This extra process for opening pin holes of the sorted products leads to loss of time. Approximately 15% of the total production time is required.
In the present technique, a minimum of 5%-7%, 30% in total, product loss occurs in each station during these processes and additionally, use of the 50-60 meters at the end of the coil is quite difficult, generally impossible. Daily cut amount of chart is only 50-60,000 units when printing and cutting amounts are calculated over 8 hours.

Figure-1 shows the perspective view of the chart printing machine (100) of the invention. The invention allows the chart production process on a single line in a continuous manner.
Figure-2 shows the detailed perspective view of the chart printing machine (100) of the invention. In the invention, there is a main body (110), to which components are connected. There is an inlet unit (101) to which the roll-shaped coil, which is the raw material of the charts to be produced, is connected. Softening and peeling of the stretch on the surface of the raw material are provided by a peel heater (102). After peeling of the protective stretch on the surface of the product, the wrapping shaft (103) allows reusing the stretch. There is a printing unit (104) on which the chart is printed. In the charts produced in the said printing unit (104), flexo printing technique, which is the most suitable technique to make it easier to hold the print on the raw material printing surface, is used. During printing, ultraviolet based paint is used. There is a printing UV drying oven (105) used for drying printed areas on the printed products. An ultraviolet-printing UV drying oven is selected as the drying oven (105), which is suitable for drying prints made with ultraviolet-based paint. There are heating cylinders (106) which allow the printed charts to be heated for easy cutting.

The cut PVC coil that will be used as a raw material for the production of the chart is connected to the inlet unit (101). The PVC coil in roll is opened and the protective stretch thereon is easily peeled off by heating via a peel heater (102). The stretch separated from the PVC is wrapped onto the wrapping shaft (103) in order to be reused later. The print-ready PVC enters code printing in the flexo printing unit (104) and printing is performed. The drying of the printed surfaces is provided by ultraviolet drying via the drying oven (105) at the outlet of the printing unit (104). Before cutting process, heating cylinders (106) heat the PVC for easy cutting. Cutting of the PVC in the cutting unit (107) is performed by the cutting element (107.1). After cutting, the edge burrs are separated via the deburring member (108) by wrapping. Thus, deburring process is performed. The charts with the burrs removed accumulate on the product discharge conveyor (109). The products are collected from the product discharge conveyor (109) and coupled by collating and attaching pins.
