Abstract
Description
[0001] CARGO OR GIFT BAG PRODUCTION SYSTEM CONVERTIBLE INTO A CARRYING BAG
[0002] Technical Field
[0003] The present invention relates to a production system for cargo bags or gift bags used by cargo companies or for transporting products or goods from one point to another, more specifically to a system that allows such bags to be reused for extended periods by revealing hidden handles upon tearing a perforated section at the mouth of the package after delivery to the end user.
[0004] Prior Art
[0005] Cargo companies (or companies that directly ship products to customers, etc.) are known to package products of commercial seller firms and deliver them to customers. Cargo companies, as a general practice, place the products inside plastic-based materials, such as nylon-type bags and dispatch them to customers.
[0006] As is known, the cargo bags used today are made of nylon material. Packaging process is completed by creating an adhesive surface at the opening of this nylon material and removing the paper on the adhesive surface, causing the two ends to stick together, which completes the product packaging and thus, the product is dispatched to the customer. This material may sometimes be paper depending on the type of products or preference of the cargo company. Product is enabled to be revealed by tearing the perforated section of the paper, plastic or another material.
[0007] However, use of these applications today requires the presence of a single-use bag. This results in significant material waste and the existence of bags that do not decompose quickly in nature, leading to their eventual usage. Today, a substantial amount of raw materials is used in the production of plastic, paper and cardboard bags (such as totes, pouches, etc.), which are widely used in carrying various products or goods in the market.
[0008] Patent application code no. CN110281583A in Chinese patent literature relates to a bottom folding mechanism for bags, which is integrated into a three-dimensional bag manufacturing machine utilizing nonwoven fabric. Bag bottom folding mechanism is characterized by oppositely positioned cranks, a drive mechanism positioned at one end of said cranks and another drive mechanism positioned at the opposite end of the cranks, which is mounted on these cranks. The drive mechanism is equipped with a sliding arrangement capable of actuating the drive mechanism to move back and forth along a bag folding channel.
[0009] Patent application code no. FR2417275A1 in French patent literature relates to the manufacture of shopping bags with cut-out handles in reinforcement bands. The handles are affixed to the bag only at their lower ends and the handle shape is cut out from the upper outer part of the bag. Attachment of the handles and punching of the cut-out are performed simultaneously along a single production line. The base of the handle may be curved in such a manner that the top of an adjacent handle fits into it, thereby forming a continuous band.
[0010] In view of the above-described disadvantages and insufficiency of existing solutions, there exists a need for improvement in the relevant technical field.
[0011] Objective of the Invention
[0012] The objective of the invention is to introduce a different manufacturing technique that provides a new approach in this field, distinct from the existing applications in the prior art.
[0013] The objective of the invention is to provide a system that allows easy integration of different modular structures into the system according to customer demands. The most important objective of the invention is to provide an environmentally friendly product through the system presented, as it prevents material waste by ensuring correct use of resources, thereby contributing to the national economy.
[0014] Another objective of the invention is to advance the primary material, strip material and other components through a continuous flow, where they are processed by the automation system at time intervals determined by the system and subject them to different processes.
[0015] In order to achieve the above-mentioned objectives, the invention comprises;
[0016] - a main feeding unit configured to advance the aforementioned base material, strip material and adhesive strip simultaneously within the same unit of time,
[0017] - an adhesive unit configured to form an adhesive layer on the aforementioned adhesive strip,
[0018] - An ultrasonic welding unit configured to affix the strip material and the adhesive strip onto the aforementioned base material,
[0019] - a perforated cutting blade configured to form a tearable line in a region near the mouth edge of the bag after the aforementioned base material is folded by means of a folding unit,
[0020] - a method for creating a pocket for placing items such as envelopes, wherein two strip materials, which extend transversely across one side of the bag, are welded onto the body with their outer portions facing outward, one strip overlapping the other, either before or after the folding unit, thereby forming a central gap,
[0021] - a side welding unit configured to apply welding on both sides of the cutting line, with reference to the aforementioned cutting line and
[0022] - a cutting unit configured to cut the bag along the cutting line with reference to the aforementioned cutting line, where both sides of the cutting line are welded, thereby forming one side of one bag and the other side of another bag.

[0068] Detailed Explanation of the Invention
[0069] Figure 1 shows the general perspective view of the bag (AB) production system subject to the invention and Figure 2 illustrates the general view of the progression and process stages of base material (A), tear-open strip material (B) and other components. In general, the system is a bag production system comprised of main feeding unit (10) that facilitates advancement of the base material (A), folding unit (50) that performs the folding operation on the base material (A) and cutting unit (90) that performs the cutting operation on the aforementioned base material (A). The bag production system, in terms of its novelty, comprises a main feeding unit (10) with the base material (A), strip material (B) and adhesive strip (D) that are advanced simultaneously and a glue unit (13) that forms an adhesive layer on the aforementioned adhesive strip (D). All materials are advanced from the main feeding unit (10) using rolls and advancing means. In the first stage, the tear-open strip material (B) is fixed to the side edges of the base material (A), which is advanced in a flat sheet form, using ultrasonic welding (15) or other bonding or sewing units. Immediately afterwards, the adhesive strip (D) is fixed onto the strip material (B). The glue unit (13) integrated into the system creates an adhesive surface on the adhesive strip (D) through at least one glue roller (11 ) and a glue reservoir (12) with the assistance of the gluing unit (13.1 ).
[0070] The ultrasonic welding (15) unit secures the tear-open strip material (B) and the adhesive strip (D) onto the base material (A) and after the aforementioned base material (A) is folded by the folding unit (50), a tearable line is formed near the mouth edge (A1) of the bag (AB) by means of the perforating cutting blade (14). Formation of this line is crucial as the strip material can be torn along the weakened surface of the cutting line and after the materials inside are removed and the hidden handles inside are pulled upward, the aforementioned handles can be attached either to the inner side or alternatively to the outer side of the bag. The bag may be used for carrying purposes while the perforated section remains closed and the product is still inside. Once converted into a bag structure, the cargo bag is configured to function as a reusable carrying bag suitable for multiple uses.
[0071] A hypothetical cutting line is formed on the bag. This line is essentially created through the welding operation of the side welding unit (91 ) as shown in Figure 9. Taking the cutting line (A2) as a reference, welding operations are performed by the side welding unit (91 ) on both sides of the cutting line (A2). The side welding unit (91 ) essentially performs the welding operation in a single step through a vertical pressing motion (hammer-anvil action). However, since it welds along two parallel paths, the central region remains unwelded. This unwelded region serves as the cutting area for the cutting unit (90) (see Figure 9’a). The cutting unit (90), which cuts the bag (AB) along the cutting line (A2) — where both sides of the line are welded — uses the cutting line (A2) as a reference such that one side of a bag forms the other side of the other bag.
[0072] In Figure 2.2, the close-up view of the modular unit that forms the handle on the bag is illustrated. The system includes a handle attaching unit (20), which enables fixation of handle strip materials (C) that are advanced along the Y-axis onto the base material (A) during continuous flow. The system is configured to allow attachment of two different types of handles. It is a handle material, wherein one of the handle types is the standard handle strip material (C) while the other is the quilted handle material (C1 ), which refers to a fabric-based handle with a hand-grip opening. Depending on the desired handle type to be applied on the bag, the handle attaching unit (20) — which has a modular structure — can be integrated into the system along the Y-axis, allowing fixation of either of the two handle types.
[0073] Figure 2 also comprises a sealing unit (25), which prevents the handles fixed onto the base material (A) from getting caught during the production process.
[0074] Figure 4 illustrates the adhesive strip (D), configured along the same laying axis (X) as the tear-open strip material (B). However, it is not a requirement for both to be aligned along the same axis. The production can be carried out by positioning them along a different axis or location as such positioning offers volumetric advantages. Figure 8 comprises a pleating formation unit (60), which is used to create pleats at the bottom of the bag (AB) if desired. Figure 8 illustrates the triangle cutting unit (70), which cuts in a triangular shape at the bottom edge (A3) of the bag (AB) from the intersection of the triangle's apex and the cutting line (A2), as well as the triangle welding unit (71), which performs triangular fixation at the bottom edge (A3) of the bag, with the fixation occurring at the same intersection point.
[0075] During the production process, a bubble layer can be formed on the inner surface of the base material (A), which corresponds to the inner surface of the final bag (AB). Depending on customer requirements, when carrying an object that may break inside the bag (AB), it is possible to prevent damage by fixing a bubble layer or protective material, which has impact-absorbing properties, onto the base material (A) during the production process using welding, sewing or adhesive techniques. Similarly, if it is desired to carry hot or cold materials (e.g., food) inside the bag, the base material (A) can be provided with insulating properties.
