Description

Making method of pre-opening zipper bag

The present invention relates to a zipper bag, especially in the manufacturing process, the male and female buckles of the zipper part are pre-expanded and then the segments are pressed together, so that the zipper part of the finished product is open in segments, so as to save time and effort for packaging. A method of making pre-opening zipper bags.

Press, the zipper bag is a kind of packaging bag with a zipper part at the open end, and the zipper part includes a male buckle clip chain and a female buckle clip chain. When it is closed, dust and water cannot penetrate the clip chain part, so it can achieve an excellent protective effect on the objects in the bag; and it is not difficult to open the closed male and female buckle clip chain. At the same time, the clip The chain can be opened and closed repeatedly without damaging its structure, so the zipper bag has been widely used in the industry.

Press again, the production of zipper bags adopts mass production mode. Most zipper bag semi-products are first produced and then cut and fused to complete the zipper bag finished products; and the manufacturing method of zipper bag semi-products can refer to the figure. As shown in 1, it uses a bag body extrusion mechanism to extrude a continuous tubular bag body 901, and then uses a zipper extrusion mechanism to extrude two male and female buckle clip chains Z1/ on the surface of the bag body along the production line. Z2 is attached to the bag body 902~903, and a cutting mechanism is used to cut out a sheet-shaped bag body 904 with an open edge Z3, and then a turning mechanism is used to turn the bag body over, and the male and female buckles are The zipper Z1/Z2 are buckled with each other and are located at the lower end of the opening edge Z3 to complete the production of the zipper bag semi-product 905. Since the zipper bag semi-product 905 has male and female buckle zipper chains Z1/Z2 buckled with each other, the zipper part Z of the zipper bag finished product 906 that has been cut and fused will also be in a closed state, as shown in FIG. 2.

When the industry uses the zipper bag for the packaging of objects, the male and female zipper Z1/Z2 of the finished zipper bag 906 must be separated from the closed state before the opening Z3 can be opened to insert the object, as shown in the figure 3; but check, the two diaphragms of the opening side Z3 are closely attached, and because of the thin thickness, the operator is very It is difficult to find the gap between the diaphragms and apply force to open the male and female buckle zipper Z1/Z2. Therefore, opening the opening edge Z3 of the finished zipper bag 906 is a troublesome task for packaging operations. In the past, there were those who used a zipper bag opener to open the zipper, such as Taiwan Patent No. M584297; there was also a layer of frosted particles on the outside of the two diaphragms at the open end of the zipper bag, and then applied fingers to push and rub the two diaphragms to stagger them. For opening the mouth of the bag, such as Taiwan Patent No. I644836. However, the use of the zipper bag opening machine requires investment in equipment, and arranging a layer of frosted particles on the outside of the two diaphragms of the zipper bag needs to increase the manufacturing cost, and the bigger problem is that the above two methods will cause the zipper part After being opened, the two male and female buckle clip chains are prone to misalignment. This phenomenon not only makes it difficult to close the clip chain, but also the failure of the male and female buckle clip chains will cause the inside of the bag. The object cannot be effectively protected by security. Press, the aforementioned dislocation phenomenon means that the male buckle clip chain and the female buckle clip chain are not in the corresponding positions, so that the male buckle clip chain cannot be smoothly inserted into the slot of the female buckle clip chain at the moment of the buckling action. As a result, the operator must laboriously adjust the corresponding position, which affects the packaging efficiency. The misalignment phenomenon often makes the operator fail to detect and make adjustments, which in turn causes the clamping chain to not be tightly closed and affects the effectiveness of the packaging.

It can be seen from the description of the prior art that in the production process of the zipper bag semi-product, the two male and female buckle zipper chains of the zipper part are extruded, formed synchronously and attached to the surface of the bag body. At the same time, in order to avoid In the finished product stage, the phenomenon that the male and female buckle zipper is not easy to buckle due to the misalignment of the male and female buckle chains. During the manufacturing process, the bag body must be turned over and the male and female buckle zipper chains must be buckled with each other; the zipper bag is a semi-finished product As the raw material, the male and female buckle clip chains that are close to each other become an established feature, and the zipper bag must face the problem that the clip chain part is not easy to open when the object is packaged; therefore, the inventor is thinking , If the zipper bag is not tightly closed when the zipper bag is shipped from the factory, the operator does not need to bother to open it; however, if the zipper bag is opened at the factory, how to overcome the male and female The phenomenon that the clasp chain is misaligned; accordingly, the pre-opening of the clasp part during the process of making the zipper bag while avoiding the misalignment of the male and female clasp chains has become the creative goal established by the inventor.

The reason is that the main purpose of the present invention is to provide a way that the male and female buckle clips of the clip chain part are separated during the process of making the finished zipper bag, and the two ends are pressed together to make it The zipper part of the finished product is open at the center and closed at both ends to avoid the misalignment of the male and female buckle zipper, thereby achieving a pre-opening zipper bag manufacturing method that is labor-saving and convenient for packaging objects.

In order to achieve the above-mentioned purpose, the present invention is a roll-shaped zipper bag semi-product made into a zipper bag finished product, and the center of the zipper part is open, and both ends are closed; its production steps include: a. Unfold zipper bag semi-products: the conveyor unit is used to continuously expand the roll zipper bag semi-products into film-shaped zipper bag semi-products, and make the sections to be processed into the work area; b. Keep away from the male and female Buckle clip chain: In the work area, a long tongue stick is used to extend into the clip chain part of the film-shaped clip chain bag semi-product, and keep the long tongue stick in the clip chain part that is continuously conveyed, so that the original closed state of the male The buckle clip chain and the female buckle clip chain are separated from each other; c. Move the zipper bag semi-product: use the clamping displacement unit to move the film-shaped zipper bag semi-product in the work area to move the zipper bag semi-product The distance reaches the width of the desired zipper bag finished product; d. Pressing zipper part: adjacent to the back of the long tongue bar, use a press jig to separate the male and female buckle zipper chains in a separated state Press and fit to make the male buckle clip chain and female buckle clip chain close again at the pressing position; e. Cutting and heat sealing the cut end: cut and heat sealing unit at the midline position of the pressing position. Fuse to make the cut at the cut to form a sealed edge, and separate the finished zipper bag from the semi-product of the zipper bag; f. Shaped sealing edge: press the fused sealing edge with a certain type unit to seal the two The sides are shaped and tightly sealed; g. Packaging zipper bag finished products: Pack the rated number of zipper bag finished products in a packaging bag.

According to the features disclosed above, in the present invention, the incision, the heat-sealing unit and the shaping unit are operated synchronously, so that the cutting part is formed with two sealing edges at the same time, that is, it is pressurized and shaped so that the sealing edge is shaped tightly.

According to the features of the foregoing disclosure, in the present invention, the pressing jig further operates synchronously with the incision, heat-sealing unit, and the shaping unit, that is, one side of the work area performs pressing operation to make the male buckle at the pressing position The zipper and the female buckle zipper are re-closed together, and at the same time, the steps of cutting, heat sealing and shaping and sealing the edge are carried out at the pressing place on the other side of the work area, so that the finished zipper bag is separated from the half product of the zipper bag and at the same time Complete the shape and close sealing of the sealing edge.

In the present invention, the long tongue bar is extended into the continuous conveying clip chain part, and the male buckle clip chain and the female buckle clip chain, which were originally in a close state, are stretched apart by the long tongue bar when they pass through the long tongue bar. Separate; and then use a pressing jig to press on the back side adjacent to the long tongue bar, then the male buckle clip chain and the female buckle clip chain in the separated state will re-close together, and the clip chain part will be covered by the long tongue bar. The stretched and pressed segment will form a closed state, while the unpressed segment stretched by the long tongue bar will form an open state; therefore, the zipper bag semi-finished product that enters the work area will be pulled away by step b. After the male and female buckle clip chain and the pressing and clamping chain part of step d. are operated, the clip chain part forms a state of closed and opened segments; secondly, the semi-finished film-shaped zipper bag is cut and heated The sealing unit cuts and fuses at the midline position of the pressing position, and the two slits form a sealed edge at the same time. Among them, one of the slits forms the outer end of the film-shaped zipper bag semi-finished product, and the second of the slits is formed with the film Where the semi-finished product of the sheet zipper bag is separated; the present invention uses a certain type unit to press the two sealed edges to form a tight fit, and make the cuts one and two respectively form the first side sealing edge and the first side of the zipper bag finished product. Edge sealing on the second side.

Furthermore, the pressing step of the present invention is to form the clip chain part into a closed state, and the incision, heat-sealing unit and shaping unit are cut, fused and shaped tightly at the midline position where the clip chain part is pressed. , Since the closed section of the pressing place is divided into two evenly, the zipper part adjacent to the first side sealing edge and the second side sealing edge is a closed section; the zipper bag semi-product of the present invention undergoes steps After step b and step d are separated and pressed together, the clip chain part is formed into a state of closed segment and open segment, and then after the cutting, fusion, and shaping close cooperation of step e and step f, the finished product For the zipper bag finished product, the open section is located at the center of the zipper part, and the zipper parts at both ends adjacent to the first side sealing and the second side sealing are respectively closed sections; Since the zipper bag made by the present invention has an open section at the center of the zipper part, the operator does not need to open the clip separately during packaging operations. The chain part, the object can be directly opened and disposed into the bag, and then the male buckle clip chain is pressed into the groove of the female buckle clip chain by closing the ends of the two ends toward the center. With the guide of the male and female buckle clip chains at the closed ends of both sides, the male buckle clip chain can be easily inserted into the groove of the female buckle clip chain without any misalignment. Therefore, the invention is made The pre-opening zipper bag has an opening at the center of the zipper part and closed at both ends, which will make the zipper part 100% closed and save time and effort for packaging.
