Definitions

  • the invention relates to production of bags made of polypropylene (PP), polyethylene (PE), non-woven fabrics and used for keeping and carrying post-sale products.
  • the present invention relates to a ultrasound welded automated manufacture system wherein wastes occurring in bag manufacturing is minimized at a high rate and where less materials are used when compared to present productions.
  • bellow form is provided on both edges of the fabric of pipe form by bellow mechanism.
  • the forming process consists of an extra process stage. Extra fabric use is also seen in process step of forming bottom surface of the bag.
  • These extra process steps of the related art have negative effects on production process and cost. Such difference in unit cost causes high costs in total cost.
  • the invention numbered TR2012/02108 described above relates to a bag (carrier bag) made from polypropylene (pp), polyethylene (pe), laminated and non-laminated fabrics, manufactured in quick way by means of ultrasonic welding without use of seams and generally used for keeping and carrying of post-sale products in retail sector (clothing, shoes, food etc.) and method for production of the bag.
  • the invention numbered TR2009/04531 relates to a sack used for packing and conserving agricultural products such as potatoes, onions and legume products such as flour, sugar, fodder etc. and any industrial products such as coal and fertilizer, granules, chemicals and limestone and containing sack bottom in the lower part, sack bottom seams made on the said sack bottom by means of seaming string and sack mouth formed in upper part and it is characterized in that it consists of a folding part formed in the said sack mouth and ultrasonic binding part providing binding of the sack mouth with heating, accordion part formed on side parts of the sack and increasing sack volume and keeping the sack in straight position when full.
  • the primary purpose of the invention is to minimize the production process and cost of bags consisting of polypropylene (PP), polyethylene (PE) non-woven fabrics in production.
  • Other purposes of the invention are:
  • Figure 1 is general schematic top view of automated manufacture system disclosed hereunder.
  • FIG. 2 is schematic view of process phases of the fabric exposed to processing by automated manufacture system disclosed hereunder. Description of Part References
  • the Figure 1 is a general schematic view of automated manufacture system (100) for bags (A3) of bellow free structure wherein polypropylene (PP), polyethylene (PE), non-woven fabrics are joined by ultrasonic welding method, material saving is provided and production process are minimized.
  • the automated manufacture system (100) consists of moving means (1 17) advancing the fabric (A) in roll (A1 ) by means of roll loading section (101 ) along production line and a braking mechanism (102) in located in the roll loading section (101 ) and providing stop and proceed motion to the embodiment on production line. It also consists of an edge folding station (103) where edges (A2) of the fabric (A) are folded and a mid-axis folding station (104) enables folding the fabric (A), which has folded edges (A2), from the middle.
  • a side edge welding station (105) fixing the folded edges (A2) of the fabric (A) and a sensor (106) adjusting cutting of the fabric (A) moves along production line in the preset bag size and adjusting the required size distance by an encoder or distance measuring system are integrated onto photocell system. It also contains a pulling-driving mechanism (107) providing movement of the fabric (A) in production line after side edge welding station (105). It has a bottom cutting station (1 10) cutting closed and folded bottom edge (A5) of the fabric (A) and a handle fitting station (1 12) fixing the strip form handles on folded edges (A2).
  • the automated manufacture system also contains a cutting station (1 15) applying cutting procedure at vertical x-axis to the fabric ready for strip handle fitting (A6) in the measurement steps determined by the said photocell (106), a handle preparation station (1 1 1 ) wherein handles in strip form are prepared and a length adjustment station (1 14).
  • conveyor (1 16) providing conveyance of the fabric with fixed handles (A7) is integrated onto the system.
  • a bottom fixing station (1 18) making ultrasonic welding or seaming as preferred with a second bottom fabric (A8.1 ) in order to close the open bottom edge (A7) of the fabric with handle (A7) in pipe form.
  • the automated manufacture system (100) is working as follows:
  • Figure 1 shows schematic view of mechanical structure of the system while figure 2 shows manufacturing stages of the product that is produced with the system and the mechanical structure.
  • the fabric (A) in roll (A1 ) is moved along production line by means of roll loading section (101 ).
  • both edges (A2) of the fabric (A) are folded and seaming is made onto these edges (A2) by ultrasonic welding.
  • the mid-axis mentioned in figure 2 is folded at folding station (104).
  • the fabric (A) is in the form where the folded bottom edge (A5) is closed and other upper edges are open.
  • the fabric (A) moved along line is cut in bag size and cutting measurement is conducted by means of photocell (106) for desired size distance adjustment.
  • Cutting the closed folded bottom edge (A5) of the folded fabric (A) is made by bottom cutting station (1 10). However, before or after bottom cutting, strip form handles are fixed onto folded edges (A2). The said strip handles are fixed at handle fitting station (1 12). The handle preparation station (1 1 1 ) transferring the strips cut in desired width to handle fitting station (1 12) is integrated onto the system. After this production stage, fabric ready for strip handle fitting (A6) is obtained. The fabric (A) is not in the bag (A3) form in this stage yet. After the cutting operation made in the length adjustment station (1 14) and the applying cutting station (1 15), the structure where bottom edge (A8) is open is obtained.
  • the bottom fabric (A8.1 ) is sewed or welded onto the bottom edge (A8) after the product whose bottom edge (A8) is open is sent to ultrasonic bottom fixing station (1 18).
  • the bag (A3) is obtained in final stage.
  • the fabrics (A) are put onto each other in cut form without need for mid-axis folding station (104) and conveyed in parallel is also possible.
  • the fabric (A) can be fed directly to the system in cut form without need of folding and then cutting. For that reason, use of mid-axis folding station (104) may not be necessary.
