[specific embodiment]
As shown in Figure 1, 2, this automatic lap winding and changing mechanism of rolling bag, be provided with the identical volume bag group 1 and 1 of two groups of structures ', two groups of volume bag groups are symmetrical set the outlet of rolling up bag making machine connecting.
Shown in Fig. 3,4,5, every group of volume bag group comprises that (volume bag bar can divide core volume bag bar and coreless roll bag bar for rolling frame 4, rotating disk 2 (rotating disk 2 of left side volume bag group '), two volume bag tubes 7,13, two transmission shafts 22,23, two winding motors 26,27 and first, second volume bag bar 9,8, there is the end that batches of core volume bag bar to be the single body of rod, is used to batch core and connects the volume bag; The end that batches of coreless roll bag bar is two bodies of rod, be used to batch centreless and connect the volume bag, shown in the figure coreless roll bag bar), described rotating disk 2 is located on the described rolling frame 4 and is rotatably connected with the rolling frame, described volume bag tube 7,13 are rotatably connected with rotating disk 2, described two transmission shafts 22,23 coaxial settings, transmission shaft 22 is in transmission connection by belt 25 with winding motor 27, and by being with 20 to be in transmission connection synchronously with a volume bag tube 13, transmission shaft 23 is in transmission connection by belt 24 with winding motor 26, and by being with 19 to be in transmission connection synchronously with a volume bag tube 7, described first, the second volume bag bar is actively installed on respectively in the corresponding volume bag tube, can be in volume bag tube elastic and rotate described first with volume bag tube, the tail end of the second volume bag bar also is provided with volume bag bar retractor device; Described volume bag bar retractor device comprises circuit orbit, drives cylinder 18 and is connected described first, second rolls up the pulley 21,16 of bag bar 9,8 tail ends, described circuit orbit is divided into fixed track guidance tape 14 and active orbit plate 15 two parts, the pulley 21,16 of described first, second volume bag bar tail end is slidedly arranged on the interior and interchangeable position of rail groove of fixed track guidance tape 14 and active orbit plate 15 respectively, described driving cylinder 18 is connected with described active orbit plate 15, also be provided with guide piece 17 on the described active orbit plate 15, active orbit plate can slide on the guide pillar of guide piece.When fixed track guidance tape 14 and active orbit plate 15 are in the same plane, two volume bag bars expose volume bag tube, when fixed track guidance tape and active orbit plate stagger, the pulley that is positioned at the active orbit plate rail groove will drive the cooresponding volume bag of its bonded assembly volume bag bar withdrawal tube, and it is in running order that at this moment another exposes volume bag bar.
As shown in Figure 3, described about two volume bag groups a rotating disk 2 ', 2 connect by connection pipe 3, first, second volume bag bars of two volume bag groups are oppositely arranged respectively, the rotating disk 2 ' outer rim of described left side volume bag group is processed with the gear teeth; Described receipts change of lap mechanism also comprises control motor 5, cutting-off device sum counter (not drawing among the figure), and described control motor 5 is arranged on left side volume bag group 1 ' locate, and is in transmission connection by sprocket wheel and gear cluster 6 gear teeth with described rotating disk 2 ' outer rim; Described cutting-off device comprise fixedly be located at described about the cross bar 10 of rolling frame top of volume bag group, cross bar 10 is provided with and interrupts cylinder 12, interrupting cylinder 12 is connected with and interrupts arm 11, its course of action is, when the first or second volume bag bar furls polythene bag to predetermined quantity, counting machine notice interrupts the cylinder action, makes to interrupt arm and rotate and interrupt the bonded assembly polythene bag.
Shown in Fig. 6,7, be provided with paper tube between the two volume bag groups about described and place chamber 29, paper tube placement chamber 29 is positioned at described first volume bag bar 9, and (volume bag bar has herein been changed a core volume bag bar, be used to batch core and connect the volume bag) side, the paper tube outlet that described paper tube is placed the chamber is provided with paper tube clamper 30, and the axle head of paper tube clamper is provided with rotation cylinder 31.
Working process of the present utility model is such: when first volume bag bar 9 when batching polythene bag, winding motor 27 work, winding motor 26 is not worked, and this moment second, a volume bag bar 8 contracted in volume bag tube 7, active orbit plate 15 and fixed track guidance tape 14 positions stagger (seeing Fig. 3,4); When first volume bag bar 9 furls polythene bag to predetermined quantity, drive cylinder 18 actions, promoting active orbit plate 15 moves, make active orbit plate and fixed track guidance tape be in same plane (see figure 5), this moment second, volume bag bar 8 stretched out volume bag tube 7, next the start-up control motor 5, make rotating disk 2 ' rotation, rotating disk 2 rotates thereupon, make first volume bag bar 9 and the second volume bag bar, 8 transpositions, roll up also transposition of bag bar bonded assembly pulley 21 and 16 with first volume bag bar and second simultaneously, the pulley 21 of first volume bag bar 9 enters the rail groove of active orbit plate 15, and the pulley 16 of the second volume bag bar 8 enters the rail groove of fixed track guidance tape 14; At this moment; winding motor 27 quits work; winding motor 26 starts immediately starts working; drive 8 rotations of the second volume bag bar and furl polythene bag; simultaneously; interrupt cylinder 12 action, make and interrupt arm 11 and rotate and interrupt the bonded assembly polythene bag, next drive cylinder 18 to move once more; drive active orbit plate 15 returns; active orbit plate and trapped orbit Board position stagger, and in the first volume bag bar 9 withdrawal volume bag tubes 13, take off company's volume bag that rolling is finished; so that carry out the operation that furls of next time; so circulation realizes not counting automatically and the receipts change of lap under the stopped status, significantly improves plastic cement and connects volume bag make efficiency.
When batching the less polythene bag of size, about first or second volume bag bars of two volume bag groups can batch separately, when batching larger-size polythene bag, about first or second volume bag bars of two volume bag groups can batch jointly and (be the synchronous rotations of the first or second volume bag bar of two volume bag groups about guaranteeing, this machine is provided with power-transfer clutch, when throw-out-of clutch, about first or second volume bag bars of two volume bag groups batch separately, when power-transfer clutch merges, about first or second volume bag bars of two volume bag groups batch jointly).
When desiring to have furled core plastic cement company volume bag, will replace to core volume bag bar this moment with the first volume bag bar and the second volume bag bar, at first paper tube 28 is positioned over paper tube and places chamber 29, because it is to be the angle of inclination that paper tube is placed the chamber, so paper tube 28 can fall toward the paper tube exit one by one successively, when paper tube drops down onto the exit, paper tube clamper 30 is clamped paper tube, before driving cylinder 18 actions, rotation cylinder 31 is action earlier, paper tube clamper 30 certain angle that tilts, the position when making paper tube be positioned at volume bag bar to stretch out, startup drives cylinder then will have the volume bag bar of core to push (see figure 7) in the paper tube, and the so continuous successively core that has that furls fixed qty is even rolled up bag.
