In slide block 89 from the translational movement (Figure 12) of side standby position, the outside of substantial amounts of folding line band 11, as long as contrary operation At the end of, after crossing, cut it, folding line band 11, at whole length and the back side, is by the 6th motor via transmission belt 92 91 carrying out, the rotation of rotating blade 85, on the other hand makees to realize by the identical translational movement of slide block 89, via cingulum 93 Device, its head adheres to gate 82 and engages toothed little gear 95 (Figure 13).It is rotatably installed on slide block 89 coaxial Admittedly closing rotating blade 85.Two pony rolls 96, are also installed in rotation on slide block 89 and the both sides being arranged on toothed little gear 95, Parallel to it, it is configured at the back side of cingulum 93, so that it is guaranteed that cingulum 93 engages toothed little gear 95.

The aforesaid function of machine 10 institute is as follows.

First of all, it is necessary to it is emphasized that normal operation for machine 10 is it is important that the principal arm 21-24 of folding device 20 Angular velocity and folding line band 11 pace V synchronous, and also the position of the angle of principal arm 21-24 and horizontal impression 12 Regularly, it is that the upstream of feed unit 15 provides, via any of device, not shown in the accompanying drawings, and as also described above Principal arm 21-24 and auxiliary 31-34 between reciprocal timing.

When starting to fold in folding line band 11 method in a zigzag manner, machine 10 is with initial shown in Fig. 1 and Fig. 2 Operating position.Intercepting component 65 to intercept the head of folding line band 11, therefore, being closed and being entered into collection device 50 in operating position Below, with horizontal support member 70 when higher position and forward facing position, have flashboard 81 (in the left side of Fig. 2) forward, and and flashboard Retract in 82 (on the right sides of Fig. 2).

When the head of folding line band 11 reaches intercepting component 65, intercepting component 65 is to move to it by fluid dynamic piston 69 to treat During operating position, this corresponds to the folding position of the first operation, and shown in Fig. 3, it remains there, until folding process knot Bundle.Flashboard 81 is also retracted, and is maintained at position forward in horizontal support member 70, and starts to be gradually reduced, and transports by second The device of motivation structure 73, folding line band 11 gradually forms lamination (pre- stacking).

During the folding position of here first operation, principal arm 21 tilts one about 30 ° of angle beta, in advance with respect to described Short axle Y of track T, prepares to intercept, with corresponding folding rod 41, the horizontal impression 12 reaching from sliding end 18.

In the second operation folding position (Fig. 4), after 15 ° of folding device 20 of clockwise rotation, i.e. when Angle beta is about 15 ° of short axle Y of relatively described track T in advance, the folding line band 11 that folding rod 41 has just contacted, and starts corresponding to It is folded up horizontal impression 12 accordingly.

Folding device 20, continues to be rotated in the clockwise direction, using principal arm 21, in the sequence, by first to the 3rd Operation folding position (Fig. 5), with short axle Y being directed at described track T, operates folding position (Fig. 6) subsequently into the 4th, at this angle Degree β is after about 15 ° of short axles Y with respect to this track T, then become the 5th operation folding position (Fig. 7), this angle beta is about 30 ° Short axle Y later in relation to this track T, with final become the 6th operation folding position (Fig. 8), this angle beta be about 45 ° with respect to After short axle Y of this track T.It is noted that rolling over to the 6th operation from the described second operation folding position The adjacent folding device 20 being intercepted and do not folded by folding rod 41 of horizontal impression 12 of folded position (Fig. 4～Fig. 8) appoint What assembly, thus, because the special exercise of auxiliary 31-34, folding line band 11 is folded in contrary direction, thus being stacked itself is in it Font.

Principal arm 21 the 6th operation folding position, principal arm 24 adjacent to it be by 45 ° angle tilt in advance with respect to Short axle Y of described track T, prepares to intercept folding line band 11 close to another horizontal impression 12, after another 15 ° of rotation, this Will be as described above in the first operation folding position.

It should be noted that each folding rod 41-44, because the satellite-type motion of oneself, its pace of change phase For described folding line band 11, therefore, in one first area, it starts to tie after the first rotation operating folding position (Fig. 3) and 90 ° Bundle (folding rod 42 position is in Fig. 3), the speed of this folding rod 41～44 rotation is substantially equal to the advance speed of described folding line band 11 Degree V, is then progressively decrease to zero, as its horizontal level between first and second quadrants of track T, then folding rod 41- 44 speed is gradually increased, until it reaches the 3rd area (offseting 180 ° with respect to described firstth area).

By this way, each folding rod 41-44 contacts the horizontal impression 12 corresponding to it in described folding line band 11, it Along with it in same speed in all of firstth area, then slow down and zero setting relative velocity, then accelerate, allow folding line band to fall Fall, folding, to following stacking.

Because folding line band 11 is gradually folded in flexuose mode, and formed and be stacked in advance in horizontal support member 70, level Support member 70 is lowered, to be allowed to close to horizontal support plane 51, this start when be with maximum shown in dotted lines in Figure 10 Raised position, via the first motion 71, horizontal support member 70, when being taken into retracted position, therefore stacking formation is shelved in advance Below horizontal support plane 51, when being then moved down into lower position, on the basis of collection device 50, show It is shown with continuous lines as shown in Figure 10.During this period, for convenience of the formation of stacking, motor drive mechanism 60 is driven, so that side wall 58 and side wall 59 swing to the horizontal pin 61 corresponding to.

When the stacking of folding line band 11 is done, folding line band 11 is cut off, and do not stop its forward direction folding device 20 Advance.Carry out so-called " flying shear ".

This point to be accomplished, one makes two flashboards 81 and flashboard 82 march forward towards another, and takes to as Fig. 9 and 11 Shown operation cutting position.So that folding line band 11 keeps the end clamping of its wedge shape.

Cutter sweep 80 is subsequently activated, the particularly the 6th motor 91, makes slide block 89 transverse translation via transmission belt 92 In folding line band 11, such to keeping between roller 86 and rotating blade 85 and in seconds, amputated by rotating blade 85.Slide block 89, carry out complete moving out, and after cutting folding line band 11, be maintained at that position, the horizontal proliferation of folding line band 11, level Flashboard 81 and 82 return towards the position shown in Fig. 3, in order to make the proper flow of folding line band 11 immediately towards described collection Device 50, sliding part 89, then return to its initial position (Figure 12).The folding line band 11 of whole backstroke laterally dissipate for whole Beyond individual backstroke remaining.

Once the cutting operation of folding line band 11 has been done, the conveyer belt 56 of collection device 50 is driven (Fig. 1 and 10), To stack the conveyer device towards known type in discharge, and it is not shown.Discharge stacking, water during this operation When flat support member 70 returns to its initial position, in top and front (Fig. 3), i.e. folding line band 11 is just cut off below, so, Above-mentioned folding cycle can repeat.

When this heap has been completed by the discharge of conveyer belt 56, horizontal support plane 51 returns to the position of its rising, Being ready to receive the pre- storehouse of another folding line band 11, being during this period on being formed at horizontal support member 70, thus ensure that machine Continuously running of device 10, need not stop folding device 20.

It will be apparent that the modification of manufacture machine 10 part and/or interpolation can describe so far, without departing from the neck of the present invention Domain and scope.

It is also clear that although the present invention is with reference to some specific examples, those skilled in the art must Realize the folding of many other equivalents of automatic packaging machine and stacking by sufficiently rigid material make in word Shape folding line band 11, the characteristic having illustrates in the claims, and the field of therefore all protections, thus be defined.
