Description of drawings
Fig. 1 is the instruction diagram from the formation of the sheet stock feedway of sheet stock reel that an embodiment of the present invention is shown.
The specific embodiment
Below, specifically describe sheet stock supply method of the present invention and device according to diagram one form of implementation.
Below Shuo Ming form of implementation can be suitable for the present invention in such occasion, promptly, in this occasion, after being filled to article in the box, sheet stock in the peristome covered with plastic film system of this box, the edge of box and the coincidence part of this sheet stock are sealed, supply with by under predetermined tension state, the sheet stock of plastic sheeting system being pulled out from the propulsive effort of box packing device side from the sheet stock reel.
In Fig. 1, symbol 1 is annular belt conveyor, sets up around sprocket wheel 2,3, and this belt conveyor 1 carries the box 4 that keeps the filling article to pack under the state of peristome above being in by predetermined space continuously.
At the box of being carried by belt conveyor 14, the sheet stock 6 of the plastic sheeting system of uncoiling covers on the peristome of box 4 after will pulling out from sheet stock reel 5, in the edge part sealing of box 4, makes box-packed commodity.
The sheet stock 6 of pulling out from sheet stock reel 5 covers through a plurality of guiding rollers 7 on the peristome of box 4 and is guided.
Edge part sealing sheet stock 6 at box 4 can adopt suitable means known in the art, so for the purpose of simplifying the description, its sealing mechanism etc. has omitted diagram, omits its explanation.
The power of the belt conveyor 1 origin self-powered moving axis 8 of annular by chain 9, drive wheel 10, and sprocket wheel 3 drive, pull out from sheet stock reel 5 by propulsive effort at the sheet stock 6 of the edge part leak free plastic sheeting system of box 4 from this axle drive shaft 8.
On the other hand, at the spool of supporting sheet stock reel 5 brake wheel 11 is installed, making becomes tensioning state ground from the sheet stock of sheet stock reel 5 uncoilings and passes through the coaxial spool brake activation power of 11 pairs of brake wheels and brake wheel 11, thereby to sheet stock reel 5 brake activation power.
That is, brake wheel 11 is connected to type variable drg 12 by chain 13, its rotation is applied application force ground constitute.
This type variable drg 12 passes through to change the electric weight of supplying with (voltage or electric current) thereby changes magnetic force, correspondingly changes its braking force with it, sells on market with titles such as powder brake, hysteresis brakes, can be adopted by suitable selection.
At the spool that axle drive shaft 8 and brake wheel 11 are installed revolution detector (not shown)s such as rotary encoder are installed respectively.By the rotating speed generation pulse of these rotary encoders corresponding to axle drive shaft 8 and spool, the pulse totalizer 14 that is transported to like that shown in dotted line.At pulse totalizer 14, calculate from the pulse of the revolution detectors such as rotary encoder that are installed on spool and ratio from the pulse of the revolution detectors such as rotary encoder that are installed on axle drive shaft 8.
The axle drive shaft 8 that is calculated by the ratio of pulse at pulse totalizer 14 is delivered to digital-to-analog converter 15 with the ratio of the rotating speed of spool, produces voltage with the corresponding size of this revolution ratio at digital-to-analog converter 15.The voltage output that is produced by digital-to-analog converter 15 is delivered to changer 16, is delivered to type variable drg 12 with the corresponding electric weight of its output, is taken place by type variable drg 12 with the corresponding big or small braking force of this electric weight.

Like this, type variable drg 12 produces the braking force with the corresponding size of variation of the ratio of the pulse of the revolution detectors such as rotary encoder that are installed on axle drive shaft 8 and spool respectively, so, when the rotating speed of spool diminishes along with the diameter of sheet stock consumption, sheet stock reel 5 and increases, the braking force that is applied to spool from type variable drg 12 diminishes, and the tension force that the sheet stock of supplying with from 5 uncoilings of sheet stock reel is applied becomes predetermined certain value ground control.
As described above, type variable drg 12 produces the braking force with the cooresponding size of variation of the ratio of the rotating speed of axle drive shaft 8 and spool, so, even the package speed of box changes the delivery speed that makes sheet stock 6 and changes, and the rotating speed of axle drive shaft 8 and spool all changes, the ratio of the rotating speed of axle drive shaft 8 and spool is not influenced by this rotation speed change yet, the braking that the variation of the revolution ratio that causes corresponding to the vary in diameter of sheet stock reel 5 changes is produced by type variable drg 12, and the sheet stock of pulling out relatively thus applies certain braking force.
Therefore, when changing package speed, not needing to pull out after 5 uncoilings of sheet stock reel tension force that the sheet stock of supply applies becomes predetermined certain value ground and adjusts the braking force that is applied to sheet stock reel 5.
In the box packing device of the form of implementation of above explanation, the package speed of establishing like that as shown in table 1 is for after per hour 1200, tension force that the sheet stock (film) of pulling out is applied are 0.6184/kgf, make this package speed per hour be changed to 2200 and 3600 s' occasion, respectively in the measured value of tension force that is applied to sheet stock shown in table 2, the table 3 etc.
As can finding out from these tables 1～table 3, pull out speed even change, also apply predetermined certain tension force at sheet stock.
