DESCRIPTION

Technical Field

The invention relates to a cardboard cutting and folding machine developed for use in the packaging industry.

The invention is in particular related to a cutting and folding machine, which turns all paper derivatives in sheet form that may be turned into boxes, into cardboard boxes for packaging purposes.

State of the Art

Corrugated cardboard material is formed by placing a paper based material rippled with threads, between two plain paper based sheets. It is often used in box production. Corrugated cardboard consists of sheets of paper usually above 0.25 mm thick. Corrugated Cardboard Box is a packaging material with the highest level of environmental compliance due to being a raw material that can be re-produced and re-recycled due to its raw material being paper. Corrugated cardboard is made of paper consisting of copper or converted cellulose fibers. The corrugated machine basically consists of two parts called wet end and dry end due to the performed operations. Corrugated cardboard production process starts with feeding liner and fluting paper of a suitable type and amount for the produced cardboard, to the corrugating machine after being picked up from the paper warehouse. In addition to these operations, in the corrugated machine, with optionally added units, it is possible to perform: coating, surface painting, tear taping and reinforce taping; preprinting with preprinted liner coils.

The box package consists of corrugated cardboard. Corrugated cardboard is manufactured before it becomes a box. During corrugated cardboard production, gear group is operated according to which quality the package will be. Corrugated cardboard is formed as a result of drying the paper in the form of rolls at high temperatures and combining it with glue. The rolled 2 paper is passed through the gear group, while humidity completely removed using high heat to create a dry ground for good adhesion. One of the papers is pressed through the gear part while the other paper receives starch glue from the bottom part and joined with the other one in the plane form. By joining two papers, one is pressed while the other is plane, the corrugated cardboard becomes curled. Today, corrugated cardboard, which is delivered in sheet form, becomes ready for use after folding and cutting operations are done manually. The manual folding and cutting operations increse the production time while creating increased workforce demand. In order to eliminate the problems experienced in manual production, various machines have been developed today. Although these machines have shortened the production time and reduced the labor demand, the space they cover is too high and the tracing, cutting and folding operations are carried out in separate sections. When box production is performed from a single corrugated cardboard sheet using the mentioned machines, the production is carried out as single corrugated cardboard by combining the outer surface paper with the glue again at the curling exit point leaving the group. When box production is performed from double corrugated cardboard, the same curling process should be carried out in a separate group. At the curling exit point leaving the second group, the production of double corrugated (dopel) cardboard is completed when combined with the other group and the outer surface paper. At the end point of the corrugated board, box cover traces are drawn while it is hot and after the edge cuts are completed, they are kept in the cooling unit for a while. The cooled corrugated cardboard can now be transferred to the box production unit. Corrugated cardboard with box cover traces pressed and edge cuts completed is completed on a slotter or a cutting machine depending on the demand. Slotter machine is a machine that can apply box edge traces, cover grooves and color printing to corrugated cardboard sheet simultaneously. After the corrugated cardboard passess through the slotter machine, it is transferred to the sewing machine or bonding machine for joining the edges of the cardboard and then the boxes that are stitched or glued are attached unopened and sent to the receiver in a bulk form.

Today, studies mostly focus on filling and taping boxes. However, the work carried out on the point of developing machines that can reduce production time and cost in order to make cardboard into boxes without the need for intensive labor was not sufficient to solve the existing problems. One of these studies is the invention of the patent no. TR201314355 titled “Box Preparation Machine”. The invention relates to a box preparation machine used for packaging products in production plants by opening all cardboard boxes and folding and gluing the lower covers.

Another study is the invention of the application no. CN20081037232. The invention describes a multi-layer winding block die-cutting folding layer blending machine. First, two layers of paper are collated and then this collated paper is sent to a transverse print line for transport through pressing and folding. The collating machine has the advantages of being compact. The equipment has a high degree of automation, the production and quality of various multi-chain printing papers, computer printing envelopes, and parcel detail lists.

Another study is the invention of the application no. CN201810589384. The invention relates to an automatic cutting and stacking machine and a working method of it. Automatic cutting and stacking machine is used for cutting and stacking metal cartons into boxes. Labor requirement is high for manual stacking. Automatic cutting and stacking machine comprises a cutting mechanism and a stacking mechanism, where the cutting mechanism and the stacking mechanism are adjacent; the cutting mechanism comprises a machine body, a support mechanism, a pushing mechanism, a cutting mechanism, a support rack, an induced air equipment and pushing arms and it is used for cutting metal cardboard; the stacking mechanism comprises a carrier device, a support device and a lifting device and it is used for automatically carrying the cut metal cardboard to a designated location to be stacked. Integration of cutting and stacking operation of metal cardboards into automation is convenient due to the automatic cutting and folding machine and operation method.

As a result, the requirement for a cardboard cutting and folding machine, which eliminates the disadvantages of the existing technique, and the lack of existing solutions made it necessary to make an improvement in the related technical field.

Herein detailed description discloses the paperboard a cutting and folding machine (10), developed for use in the product packaging sector, only for exemplary purposes for better understanding the subject, without any limiting effect.

The cardboard cutting and folding machine (10), shown in Figure-1 , has been developed to turn corrugated cardboard (20) into cardboard boxes for packaging purposes without the need for manpower. The design of the said cardboard cutting and folding machine (10) allows savings of space occuppied inside the facility by reducing the volume. In the said cardboard cutting and folding machine (10), an automatic feeding unit (11 ) is positioned to hold the sheet cardboard (20) and to lower one sheet cardboard (20) by measuring it. An automatic measuring device

(12) positioned in the said cardboard cutting and folding machine (10) measures the dimensions of the sheet cardboard (20) and transfers the information of width, height and length. In order to fix the sheet cardboard (20) delivered into the cardboard cutting and folding machine (10) onto the cutting surface, a moving vacuum plate

(13) is introduced. A piston (14), which provides the movement of the mentioned vacuum plate (13), allows the cardboard (20) in the automatic feeding unit (11 ) to be lowered to the cutting surface by means of its downward and upward movement. A carrier (17), which is introduced on the x-axis of the mentioned cardboard cutting and folding machine (10), comprises cutting and tracing units (15), waste disposal units (16), glue applying unit (18) and vacuum holder unit (19) and carry them to the point where the operation will be performed. The mentioned cutting and tracing units (15) provide the tracing of the folding points of the sheet cardboard (20) and allows various cuttings to form the box volume and box form. After the said sheet cardboard (20) is cut, the waste products that are left outside are removed by means of the waste disposal units (16). The mentioned glue applying unit (18) applies glue to the junction points so that the edges of the boxes are adhered together before folding. The mentioned vacuum holder unit (19) ensures that the glued region is folded to be adhered, by lifting the area to be folded.

After the loading by placing an amount of sheet cardboard (20) to the automatic feeding unit located at the upper part of the mentioned paperboard cutting and folding machine (10) located at the top of the auto feed unit (11 ), width, length, and height information delivered from the automatic measuring device (12) located on the belt, and the process of forming the boxs from the sheet cardboard (20) commences. 1 sheet cardboard (20) is received from the feeding unit (11) when the moving vacuum plate (13) located at the middle surface of the cardboard cutting and folding machine (19) is moved up by the piston (14), and the vacuum plate (13) is pushed back down to vacuum the entire sheet cardboard (20) to fix it on the cutting surface. The shape of the box is determined with the help of the cutting and tracing units (15) on the front side of the carrier (17) on the x-axis and the waste disposal units (16), based on the width, height and length information received from the automatic measuring device (12). For determining the shape of the box, by means of the carrier (17) located on the x-axis and the glue applying unit (17) located on its back side, the open part at the bottom of the box is folded and made ready with the top open for use/loading to allow placing the products. After manually filling the boxes that come out of the said cardboard cutting and folding machine (10) with one surface open, the shipment becomes ready for delivery once the top part is closed and taped.
