Definitions

  • the present invention generally relates to a machine for attaching handles made of a heat sealable strip on a carrying bag.
  • the present invention particularly relates to an automatic handle sealing machine which is suitable for sealing more than two handles simultaneously on a bag.
  • the handle sealing machine according to the present invention saves labor, time and allows continuity of the production with safer manufacturing process.
  • Heat sealable materials such as non-woven bags are preferred nowadays for producing carrying bags because they are capable of being used many times and also being found environment friendly and resistant.
  • a non-woven fabric is made of polyolefin fibers, and particularly of polyester and rayon without knitting.
  • handles are generally attached to a bag mouth by ultrasonic sealing method. These machines which seal the handles on a bag mouth are well known in prior art. Attaching handles on a bag is the most time wasting step in a production line. Generally, the step involves manual positioning of the handles. An operator put a handle on the mouth of the bag where the handle is associated with said mouth portion by sealing or any other appropriate method.
  • the present invention is concerned with a handle sealing machine (100) for attaching more than two handles, more particularly four handles on a bag at one time, comprising a main unit (110) where handles are attached to a bag, and a supply unit (102) to continuously provide strips (16) in rectilinear form in order to form the handles (104, 105).
  • the sealing machine according to an embodiment of the present invention is shown as a whole in Fig. 1 .
  • the supply unit (102) according to an embodiment of the present invention is shown for instance in Figures 8 and 9 where the said strip (16) is winded on reels (27) employed therein. There may be plurality of reels (27), i.e. more than two, depending on the number of handles to be attached onto a particular bag.
  • the machine of the present invention further comprises a sealing mechanism (39) having two horns (22) to press and seal the handles on a bag mouth.
  • Said supply unit (102) on the other hand has a plurality of rollers (1) on a corresponding supporting bar (36) for guiding and positioning the strips (16) through the main unit (110).
  • Required tightness is adjusted by tensioning means (2) associated with the strip (16), and said tensioning means (2) moves on an elevator unit (29) moving along vertical direction (y) provided on each supporting bar (36) of the supply unit (102).
  • Strips (16) are cut in required length in the strip cutting station (103) of the main unit (110).
  • a strip stopping means (17) runs to immobilize at least two strips (16) so that these immobilized strips constitute the longer handles (104) while the moving strips by way of retraction of the tensioning means (2) will constitute shorter handles (105).
  • rotating arms (21) swiveled axially make the handles (104, 105) ready to be sealed on a bag mouth in U shaped form by turning and then the ends of the handles (104, 105) are drawn between the horns (22) which will press the handles (104, 105) on a bag mouth.
  • the operator of the machine (100) holds a bag in a proper position and presses the button to seal the handles (104, 105) and then the process is completed.
  • the main unit (110) comprises a claw element (33) for holding and delivering the strips (16) to the strip holders (25, 44).
  • the claw element (33) moves up by means of an elevator mechanism (34)
  • the strip holders (25, 44) move forth in direction (z) and the first strip holder (25) holds the strips (16).
  • the claw element (33) releases the ends of the strips (16), and the first strip holder (25) pulls the strips back (16) in direction (x) so as to move away from the claw element (33).
  • the strip stopping means (17) immobilizes at least two strips (16), the length of the remaining strips (e.g. two longer strips) stay constant (104), while the other two (105) are shortened.
  • the present invention aims at providing an advantageous assembly for sealing of more than two handles in situ as opposed to the prior art arrangements, although the assembly of the present invention is perfectly suited for attachment of four handles at once, two of which are longer than the remaining two such that two handles are formed for shoulder use, and the remaining shorter handles are designed for hand carriage. Therefore, in the most preferred embodiment of the present invention the handle sealing machine disclosed herein is designed for attachment of four handles at once to a bag, and in the following, this embodiment will be disclosed in detail with reference to the drawings.
  • a handle sealing machine (100) which is used for attaching handles on a bag mouth, particularly four handles, two of which being short and the remaining two being longer, the said handles can be attached to a bag simultaneously in a machine (100) comprising basically a main unit (110) and a supply unit (102) as shown in Fig. 1 .
  • the handle and the bag can be of any heat sealable material such as non-woven fabric and various plastics whereas the sealing method may involve heat and/or ultrasonic welding methods, all of which shall be referred to as a "sealing method" in the following explanations.
  • the main unit (110) of the machine (100) stands for operationally attaching of the handles onto a bag, and the supply unit (102) is configured to supply continuously a strip material (16) of the handles to be attached on the bags.
