摘要： PURPOSE:To avoid the unevenness of fusion power of a heat seal part by providing a heat sealer with two electric heaters at the upper and lower parts thereof in order that the temperature of the seal edge of a heat sealer for heat sealing the bag strip material consisting of thermoplastic film, tube, etc., may be made nearly uniform all through the operation time and the sealing length. CONSTITUTION:A heat sealer body 10 is provided with electric heaters in two tiers and a first heater 15 disposed close to a heat seal edge 11 is normally energized and a second heater 16 is turned on and off by a thermostat to minimize the unevenness of the temperature of the heat seal edge 11, whereby the fusion power of bag strip material can be imparted to each bag throughout the length of its heat seal part to attain a constant fusion of the heat seal parts.

摘要： PURPOSE:To ensure that more accurate and stable transport control is performed by reducing the frequency of changing the rotary angle of a servo motor to eliminate the generation of a hunching phenomenon using a method for aligning the operation of the servo motor to a mark pitch and adjusting the operation automatically in transport control and its device. CONSTITUTION:A servo motor 10 rotates and an approximate matching signal is connected near the end of each operation, if a mark M is attached to a bag material strip F. In this case, if a mark detection sensor 12 generates a detection signal, an AND signal becomes a count clear input signal and it is connected to an input terminal 13b. Finally the remaining value of a counter is cleared to 0. The counter 13 generates an output signal for completion of counting, and stops the servo motor 10 which is already at low speed and a transport roller 15 immediately. This mark detection signal is generated at three different timings, each of which causes varied action to occur.

摘要： PURPOSE:To form a sufficient air layer by slightly pulling back an internal packaging band right before the upstream side of an external film band is closed, for a packaging method for which an internal packaging body is packaged by an external packaging film, and air is encapsulated between the internal packaging web band and the external packaging film band at the time of sealing. CONSTITUTION:When an object to be packaged P is inserted between a pair of, top and bottom, internal packaging webs W, a vertical sealing means 13 and a lateral sealing means 14 are operated to seal the internal packaging webs W, in which the object to be packaged P is stored, and at the same time, the internal packaging webs W and an external packaging film band F, which are pinched by a pinching means 48, are carried by a specified dimension. Also, power is connected to a heating wire which is provided on an external packaging vertical sealing means 44, and at the same time, the valve of a low pressure air source is opened, and low pressure air is blown in the external packaging band F through a pipe 54. Then, only the external packaging film band F is pinched by closing a holding member 45, and under this condition, the internal packaging webs W are pulled back by driving the carrying- driving means slightly in the opposite direction, and the encapsulated air quantity in the external packaging film band F is sufficiently ensured.

摘要： PURPOSE:To smoothly deliver a bag material belt or the like after a bag presser plate is sufficiently retracted by a method wherein when the bag material belt is intermittently fed on a servo motor-driven conveyor with a small set cycle number for operating a heating sealer and the bag presser plate, every servo motor start timing is automatically delayed. CONSTITUTION:An inverse-number voltage of a specified voltage of a second motor M2 for vertically moving a heating sealer 11 and a bag presser plate 16 is compared with a rising voltage of a means 30 for increasing voltage with time by a comparison circuit 32. An output signal of the comparison circuit 32 serves as every start signal of a servo motor Ml. for intermittently driving a conveyor. Namely, when a set cycle number by the second motor M2 is small, a timing of generating an output signal from the comparison circuit 32 is delayed, whereby every start of the servo motor Ml is delayed. In this manner, a bag material belt or the like can be smoothly delivered after the bag presser plate 1.6 is sufficiently retracted.

摘要： PURPOSE:To steplessly vary the phase between two synchronous shafts during operation by providing a reciprocation source mechanism on each of both synchronous shafts, supporting both synchronous shafts in parallel to each other on a machine frame and fixing sprocket gears having the same number of teeth with which a common endless chain is engaged to both synchronous shafts respectively. CONSTITUTION:The operating phase of the cam 22 of a second synchronous shaft 20 is advanced with respect to the operating phase of the cam 12 of a first synchronous shaft 10, with the moving direction of an endless chain 30 between the sprocket gears 13, 23 of the two synchronous shafts 10, 20 as a reference. A slider 41 is moved in the direction of expanding or increasing the chain 30 of the loop portion (33a or 33b) in the portion where the shaft 10 side is positioned on the lower course of the shaft 20 side while reducing or contracting the chain of the loop portion on the other side, by rotating a feed screw. Thereupon, the chain 30 of the portion engaged with a gear 23 is moved in the rotating direction in line with the moving quantity of a slider 41 to draw in the chain 30 on the upper course side position of the gear 23 into the gear 23, advancing the phase of the shaft 20 with respect to the shaft 10.
