Definitions

  • the present invention relates to a bag sealing apparatus such as a bag sealing apparatus in a bag-making machine or a bag mouth sealing apparatus in a bag-filling packaging machine, etc.
  • a bag sealing apparatus in bag-making machines and a bag mouth sealing apparatus in bag-filling packaging machines perform sealing by holding specified locations on the bag (for example, both side portions and the bottom in the case of a bag-making machine, or the bag mouth in the case of a bag-filling packaging machine) using a pair of sealing means (sealing member and receiving member) that are disposed facing each other.
  • the sealing systems used include a heat sealing system in which bags are held by a pair of heating plates which contain heaters and are disposed to face each other, an impulse sealing system in which bags are held by a heater block that contains heater wires and a receiving block which is disposed facing the heater block, and an ultrasonic sealing system in which bags are held by a horn that vibrates ultrasonically and an anvil that is disposed facing this horn.
  • a means that uses an air cylinder and a means that uses a cam are commonly employed as the driving means used to cause the sealing member and receiving member to approach and separate from each other.
  • air cylinders are used in Japanese Utility Model Registration Nos. 2600077 and 2607484, while in Japanese Utility Model Registration No. 2605892, the raising-and-lowering device that raises and lowers the driving shaft 11 (paragraph 0011 in the same reference) appears to be a cam that is rotated by the driving source of the bag-filling packaging machine.
  • the present invention is to solve such problems encountered in conventional sealing apparatuses used in bag-making machines or bag-filling packaging machines.
  • the main object of the present invention is: to make it possible to slow the operating speed at the instant of closing of the sealing means compared to the operating speed in the stroke up to this point, even in cases where the overall operating speed of the sealing means is large, to prevent a drop in performance and decrease in useful life caused by wear of the sealing means, and a deterioration in the working environment caused by the generation of impact noise, and to make it possible to maintain the sealing time at a constant time even if the production rate of the bag-making machine or bag-filling packaging machine varies, so that a high sealing quality is obtained.
  • the apparatus comprises a sealing member and receiving member that can open and close (or can be separated from and come into contact with each other) and that are constantly urged in the direction to open (or opposing directions), and a driving means that closes (or contacts) the sealing member and receiving member; and the above driving means comprises rubber tubes which expand in the radial direction and contract in length when compressed air is supplied, and which recover to its original state when this compressed air is discharged, and the rubber tubes are connected to the sealing member and receiving member so that the sealing member and receiving member close (or come into contact with each other) when the length of the rubber tubes contracts.
  • the rate at which the length of the rubber tubes contracts is large while the pressure difference between the pressure inside the tubes and the pressure of the supplied compressed air is large and decreases as this pressure difference decreases (i.e., in the final stage of pressurization). Accordingly, by appropriately controlling the pressure of the compressed air, it is possible to obtain operating characteristics in which the opening-and-closing speed of the sealing member and receiving member is increased, and this speed is decreased at the instant of closing.
  • the sealing time can be maintained at a constant time even when the operating speed is altered in accordance with changes in the production rate of the bag-making machine or bag-filling packaging machine.
