Description

DESCRIPTION IMPROVED NEW GENERATION AUTOMATIC POLYPROPYLENE (PP) AND POLYETHYLENE (PE) BAG (SACK) INTESTING WEIGHTING MACHINE This invention; Transporting of Polypropylene (hereinafter abbreviated as PP) and Polyethylene (hereinafter abbreviated as PE) bags separately to the workstations with a triple bag carrying and stacking table (hereinafter abbreviated as conveyor belt) system, then automatically nesting the PP and PE bags It is about the automatic bonding (welding) of the mouth parts of the interlocking PP and PE bags. PP and PE bags; These are bags that are frequently used especially in the packaging, storage and/or transportation of fertilizer, sugar and animal feed, and generally in similar areas. When using these bags, a PE bag is placed inside the PP bag and thus the product is packaged. In the known state of the technique; First, a PE bag is manually attached to the loom, then a PP bag is manually placed on the PE bag attached to the loom, and then, while both bags are on the loom, the mouth parts of both bags are folded together (cuffs are made) and they are removed from the loom together without gluing, stacked and baled. patented technique; It describes an automatic machine for turning blown film rolls made of woven fabric from PP tapes and PE film into bags and then welding the bag mouths. The machine is already written in German as Garment Machine for the Automatic Production of Double Bags. This requested invention; Transporting Polypropylene (hereinafter abbreviated as PP) and Polyethylene (hereinafter abbreviated as PE) bags to the workstations separately by the conveyor belt system, then automatically nesting the PP and PE bags at the same station and placing the intertwined PP and PE bags. It is about automatically gluing (welding) the mouth parts and finally preparing them for baling by stacking them in the desired number. In the Claimed Invention, pre-produced PP and PE bags are used. And it explains how the bag mouths are welded with an ultrasonic welding device. But in the technique of the patent EP0140360 A2, HUEMER FRANZ X, 1985-05-08; He uses a sewing machine, not a welding machine, and cannot explain how the bags are "welded". Requested Invention; There are 4 independent workstations arranged around the platform (workstation no. 1 to obtain the first final bag, workstation no. 2 to obtain the second final bag, workstation no. 3 to obtain the third final bag and workstation no. 4 to obtain the fourth final bag). and also the lower and upper part welding applications are completed at the station and 1 bag is produced, but in the Requested Invention, each process is completed in 3 steps at the same workstation and 4 final bags are produced simultaneously. It is different from the machine in its technique and, even if desired, it cannot be considered as a machine that can be built by competent personnel by adding more workstations to the machine in the EP0140360 A2, HUEMER FRANZ X, 1985 -05-08 patent technique. There are. In this technique, the rotating platform consists of 6 workstations arranged around it (workstations no. 1, 2 and 3 for the first final bag; workstations no. 4, 5 and 6 for obtaining the second final bag) and workstation no. 1 and work no. 4. There must be simultaneous operation between workstations, between workstations 2 and 5, and between workstations 3 and 6. 2 final bags are produced simultaneously. There is a slave operation between workstations. This means; In case of an operational problem (malfunction) at any workstation, all other workstations must also stop and the machine cannot operate without solving the problem. In the current technique; There is a patent [(TR 2016 17083 B, BAKIR GÖKHAN, ], registered by the European Patent Office, which was also made by us. In this technique, there are 4 independent workstations arranged around the platform (work station no. 1 to obtain the first final bag, work no. 2 to obtain the first final bag). station no. 3 to obtain the second final bag, work station no. 4 to obtain the fourth final bag) in each workstation; In order for the PP bag to be installed, the triple conveyor belt in the group (bag carrying and stacking table) must be activated and the PE bag stacking part and the fixed bench are in the same line. In the second process, in order for the PP bag to be installed, the triple conveyor belt in the group must be activated again. It is mandatory for the bag stacking section to be aligned with the fixed bench on which the PE bag is previously attached. In the third process, the triple conveyor belt in the group should be activated again and the PP+PE bag stacking section should be aligned with the fixed bench where the PP and PE bags are previously attached. It is mandatory. For this reason, the triple conveyor belt as a whole must move continuously during the PE bag, PP bag and PP+PE bag processes and ensure that it is aligned with the bench in each process. In addition, a fixed shaftless pneumatic cylinder was used for the installation and removal of PE, PP and PP+PE bags on the loom. Since the group of three conveyor belts must constantly move forward and backward horizontally, there are three operations dependent on three separate points between the first operation, which is attaching the PE bag, and then the second operation, which is the installation of the PP bag, and finally the process of removing the PP+PE bag from the loom. This means; In case of alignment error (position error) between the conveyor belt and the machine, which may occur due to the horizontal movement of the moving triple conveyor belt, the workstation will have to stop and the machine will not be able to operate without solving the problem. This three-point operating principle is equally valid for each of the other workstations (no. 1, no. 2, no. 3, no. 4). However, the Requested Invention; It consists of 4 independent workstations fixed around the fixed platform and an industrial robot movement mechanism working on six axes with a fixed triple conveyor belt at each workstation. This means; The triple conveyor belt (PE bag stacking part, PP bag stacking part, PP+PE bag stacking part) will remain stationary as a group, and the industrial robot movement mechanism working on six axes will activate and first attach the PE bag to the counter, then attach the PP bag to the previously PE-attached counter. Finally, the welded PP+PE bag will be removed from the loom. In this way, no alignment error (position error) will occur between the triple conveyor belt and the bench at any workstation, and the system will continue to operate without the processes of PE bag, PP bag and PP+PE bag being dependent on each other. Due to the independent operation of PE bags, PP bags and PP+PE bags at the workstations, downtime in the Requested Invention will be reduced and thus production can be increased. Moreover, 4 final bags (nested and welded) are obtained per unit time by the Requested Invention. Therefore; Requested Invention, TR 2013 02136 B, BAKIR GÖKHAN, , (AT 521187 B1 cannot be considered as a possible machine that can be made by competent personnel by adding more workstations to the machine in this patent and the independent working principle between the conveyor belt and the fixed bench. In current practice, PP and PE Failure to nest the bag properly or the cuff being damaged during transportation and the PE bag slipping into the PP bag causes the product (fertilizer, sugar, animal feed, etc.) to flow and fill between the PP and PE bags during filling. This causes the bags filled in this way to burst or the product ( fertilizer, sugar, animal feed, etc.) loses its properties when in contact with air/moisture or water and cannot be used. With the product of the invention developed to overcome these problems, PP and PE bags are automatically intertwined and PP and PE bags are intertwined. It is aimed to automatically glue (weld) the mouth parts of the bags, allowing the product (fertilizer, sugar, animal feed, etc.) to be properly filled in the filling unit and then safely transported. and therefore the automatic bag nesting (placement) machine developed to achieve the mentioned purposes of the product is given in the attached figures, and the explanation of the figures is given below: Figure 1: Isometric view of the Improved New Generation Automatic bag nesting machine Figure 2: Triple Bag carrying and stacking table (PE bag part, PP bag part, PP+PE bag part) Figure 3: Upper Vacuum and Six-Axis Industrial Robot movement mechanism Figure 4: Lower vacuum and vertical-horizontal movement mechanism Figure 5: Bag nesting Figure 6: Upper and lower ultrasonic bag welding machine and movement mechanism Figure 7: Bag nesting platform. The parts in the figures are numbered one by one, and the corresponding numbers are given below; 1- Triple Bag carrying and stacking table (PE bag part, PP bag part, PP+PE bag part) 2- Vacuum System (Upper Part) 3- Sensor 4- Six-axis industrial robot movement mechanism - Vacuum System (Bottom Part) 6 - Shaftless Pneumatic Cylinder (Vertical Positioning) 7- Shaftless Pneumatic Cylinder (Horizontal Positioning) 8- Support Part for Ultrasonic Welding 9- Bag Nesting Machine - Lower and Upper Ultrasonic Welding Machine 11- Bag Nesting Machine Platform Subject of the invention The machine consists of a triple bag carrying and stacking table (l) with conveyor belts (PE bag, PP bag, PP+PE bag) (Figure-2), vacuum system on the upper part (2), sensor (3 six-axis industrial robots) movement mechanism (4) (Figure-3), sub-vacuum and vertical-horizontal movement mechanism (Figure-4) on which there is a vacuum system (5), shaftless pneumatic cylinder (6), shaftless pneumatic cylinder (7); bag nesting machine (9) (Figure-5) with a support piece (8) for it; ultrasonic bag welding machine with upper and lower ultrasonic welding machine (10) and its movement mechanism (Figure-6); It consists of a combination of 4 workstations consisting of a bag nesting bench platform (11) (Figure-7). 4 workstations are coordinated and connected to each other by the bag sighing bench platform (11) for automatic nesting of PP and PE bags, automatic gluing of the mouth parts of the nested PP and PE bags, and stacking and baling in the desired number at the final station ( Figure 1). As a result of this coordination; The 17th, 27th, 37th and 47th workstations operate simultaneously and completely independently of each other. Therefore, while only the 17th workstation is operated to nest the 17th bag, only the 27th workstation is operated to nest the 27th bag simultaneously and independently, only the 37th workstation is operated to nest the 37th bag simultaneously and independently, and only the 37th workstation is operated to nest the 47th bag simultaneously and independently. For nesting, only the 47th workstation is operated. In this way, 4 final bags are nested per unit time. The operation of the system is as follows: At the first workstation, the six-axis industrial robot movement mechanism (4) is activated by the vacuum group (2) with the help of the sensor (3) to hold the PE bag on the conveyor belt (l) and the PE bag is lowered towards the stack. The upper layer of the PE bag is vacuumed by the vacuum group (2) approaching the PE bag. With the help of the sensor (3), the six-axis industrial robot movement mechanism (4) is activated and the vacuum group (2) holding the PE bag is started to move upwards until the bag reaches the height of the nesting bench (9). When the vacuum group (2) and the bag nesting bench (9) are reached to the same height, the six-axis industrial robot movement mechanism (4) is moved horizontally towards the bag nesting bench (9). When the vacuum group (2) in the upper part is started to move horizontally, the vacuum group (5) in the lower part works simultaneously with the vacuum group (2) in the upper part with the help of the sensor (3), in order for the bag mouth to be fully opened and installed on the counter without any problems, and holds the bottom layer of the PE bag and removes the inside of the bag. By continuing the simultaneous horizontal movement towards the stuffing bench (9) for a short distance, the PE bag can be attached to the stuffing bench without any problems. Then the vacuum group (5) at the bottom returns to its initial position. Then, the six-axis industrial robot movement mechanism (4) is activated by the vacuum group (2) with the help of the sensor (3) to hold the PP bag on the conveyor belt (l) and the PP bag is lowered towards the stack. The upper layer of the PP bag is vacuumed by the vacuum group (2) approaching the PP bag. With the help of the sensor (3), the six-axis industrial robot movement mechanism (4) is activated and the vacuum group (2) holding the PP bag is started to move upwards until the bag reaches the height of the nesting bench (9). When the vacuum group (2) and the bag nesting bench (9) are reached to the same height, the six-axis industrial robot movement mechanism (4) is moved horizontally towards the bag nesting bench (9). When the vacuum group (2) in the upper part is started to move horizontally, the vacuum group (5) in the lower part works simultaneously with the vacuum group (2) in the upper part with the help of the sensor (3) to hold the bottom layer of the PP bag and hold the bottom layer of the PE bag in order for the bag mouth to be fully opened and mounted on the bench without any problems. By continuing the simultaneous horizontal movement towards the attached bag nesting bench (9) for a short distance, the PP bag is placed on the PE bag on the bench (9) without any problems. Then the vacuum group (5) at the bottom returns to its initial position. Then, the upper and lower layers of the bag with a PE bag inserted into the PP bag are activated simultaneously by the upper and lower ultrasonic welding machine (10) with the help of the sensor (3) to perform the bonding process and welding is performed. After the PP and PE bag layers are bonded, the six-axis industrial robot movement mechanism (4) is activated downwards with the help of the sensor (3) so that the upper vacuum group (2) holds the final bag and the upper part of the bag is vacuumed. Then, with the help of the sensor (3), the six-axis industrial robot movement mechanism (4) begins to move horizontally towards the conveyor belt (l) to remove the final bag from the bag nesting bench. When the horizontal movement starts, the lower vacuum group (5) is simultaneously vacuumed from the bottom of the bag with the help of the sensor (3) so that the bag can be removed from the bench (9) without any problems, and the vacuum is terminated by moving a certain distance towards the conveyor belt (l). After the bag leaves the bench (9), the upper vacuum group (2) continues to move and when the conveyor belt (l) is reached, the six-axis industrial robot movement mechanism (4) is activated with the help of the sensor (3) and moves downwards, terminating the vacuum. The bag is placed on the PP+PE bag part on the conveyor belt (l). Then, to nest the new bag, the upper vacuum group (2), which is moved horizontally with the help of the six-axis industrial robot movement mechanism (4) and the sensor (3), is positioned on the PE bag stack section of the conveyor belt (l). In this way, 1 final bag is obtained, with the mouth part welded by being nested in one station. At the 27th, 37th and 47th stations, which have the same working principle, operations are carried out simultaneously and independently of each other, and a total of 4 final bags are obtained in the same time. Thanks to the system, PP and PE bags are automatically nested and the mouth parts of the nested PP and PE bags are automatically glued. Bags with glued mouths allow the product (fertilizer, sugar, animal feed, etc.) to be filled properly in the filling unit and then transported safely, preventing the bag and therefore the product from being wasted. Additionally, 7 cm of PP bag is used to make cuffs. Savings are also achieved from the longer length of the PE bag produced and the expense paid for the bag sighing service. In order to facilitate explanation without restricting the usage area of the product, the machine and coordinated system described for fertilizer bagging can also be used in packaging similar products (sugar, animal feed, etc.) other than fertilizer.TR TR TR
