Description

Bag is tied the device that carries out segment

The present invention relates to a kind of by a blade moving up and down to especially by the device that bag bundle that fibrous material constitutes is carried out segment that is extruded resemble the tobacco, said blade bumps against on the cutting anvil after finishing once cutting off.

A kind of such device has been described in EP-A-0582139.At this, the bag bundle is shifted onto on the cutting position by a slide block, and in this position, bag bundle to be slit is compressed against on the locating surface.The cutting knife that can move vertically carries out segment to the bag bundle, and segment falls.This known devices is not cut anvil.

Described the sort of device when in US-A-4977907, having described another and beginning.At this, the segment of a bag bundle bumps against a cutting knife cutting on the cutting anvil by one, and segment drops on downwards on the band conveyor.After penult segment cutting, last segment is caught by a clamping device and is transported on the band conveyor by the swing of cutting anvil.

Any a kind of method of after the cutting of bag bundle, further carrying segment that is of the present invention.

Solution according to the present invention is a cutting anvil that basic horizontal is placed in cutting-off process or the swing or the mobile device of its parts, and purpose is after each the cut-out segment of cutting to be removed from its cutting position.

Aforementioned cutting knife mainly is vertically to move from the top down and on the contrary.It can carry out cutting movement with horizontal part in this case.Further planform of the present invention and further layout can be learnt from dependent claims.

Special benefits of the present invention is, the segment of cutting by the cutting anvil swing or move can be guided downward to conveyer, the segment of cutting be with an one big face lie low on conveyer and can side by side be transported away.

Further specify the present invention by means of embodiment.Wherein:

Fig. 1 to 6 is schematic diagrames of the motion process when a bag bundle is carried out segment,

Fig. 7 is a kind of mobile form of cutting anvil,

Fig. 8 be realize Fig. 1 to 6 motion process have the blade fallen and in a kind of structure of the cutting anvil of cutting position,

Fig. 9 is the cutting anvil under deflection state according to Fig. 8,

Figure 10 is the another kind of mobile form of cutting anvil.

Fig. 1 to 6 has described a kind of conveyer belt 1 that controllably drives of guiding on roller 2 and 3.This conveyer belt is driven by a drive unit of not describing out, and bag bundle 4 directions along arrow 6 are transported to cutting position A, and in this position, segment 7 is by blade 8 cuttings that can move vertically.Also can use other suitable cutting devices to replace shown blade 8.Cut-out is to finish along corresponding moving down in the process of arrow 9 at blade 8, and after this, blade moves up against arrow 9 once again, so that the distance of the width of a segment 7 can further be carried bag bundle 4 along corresponding arrow 6 by conveyer belt 1; Then move down to finish next time along corresponding arrow 9 again and cut off or the like.Bag bundle 4 is to be made of the tobacco leaf that is squeezed in that level is piled up.The drive unit of blade 8 is depicted in Fig. 8 and 9, as position 22.A cutting anvil 11 that is abutted against on the conveyer belt 1 is on the A of cutting position, and said cutting anvil has two

parts

11a, 11b and a notch 11c who is arranged on therebetween.Said blade 8 has a reinforcement 10.During the cutting of segment 7, a supporting surface 12 is arranged at apart from its scope of freedom 7a to be had on the position of a slight distance, so that on the one hand in cutting with support segment and do not hinder 8 pairs of bags of blade to tie 4 the discharges that enter and combine therewith on the other hand again in the moving process on the band conveyor 16 that drives along corresponding arrow 15 of

roller

13,14 guiding to one subsequently.Said band conveyor 16 is controllably driven by a drive unit that is not described.After once cutting off and after the segment 7 of cutting has been transported, said supporting surface 12 is pushed to position A by a drive unit that is not described along corresponding arrow 17 and goes up (Fig. 4) and next be open slightly above the distance (Fig. 5 and 6) of a segment width from position A on the direction of arrow 6 with aforementioned bag bundle face 7a.This just has such advantage, i.e. last segment 7 of a bag bundle can be clamped by subsequently bag bundle and said supporting surface and keep one's legs.When the common mobile end of bag bundle 4 and supporting surface 12, the distance that supporting surface moves from the bag bundle is slightly greater than the width of segment.

The lower end of cutter living 8 can enter into the notch 11c of cutting anvil 11 slightly when cutting off, after each cut-out is finished, a drive unit (position 22) of describing in Fig. 8 and 9 makes 11 swings of cutting anvil along corresponding arrow 18, this can easily be transported on the band conveyor 16 segment 7 of cutting as special shown in Fig. 3.The section 7 of cutting is cut anvil 11 supports and is guided like this in course of conveying, and they lie low on band conveyor with an one big face.After transporting, cutting anvil 11 is got back on the position shown in Figure 4 against the direction of arrow 18 pendulum.

What therefore, Fig. 1 to 6 showed one by one is following motion state:

Fig. 1 is before once cutting off, and is in bag bundle 4, blade 8 and the supporting surface 12 of initial position,

Fig. 2 enters into bag bundle 4 up to cutting anvil 11 and arriving the blade 8 of its notch 11c and supported segment 7.

Fig. 3 carries the segment 7 of cutting and be directed on the band conveyor 16 along the cutting anvil 11 of corresponding arrow 18 swings,

To be supporting surface 12 move to process on the face 7a along arrow 17 directions to Fig. 4,

Fig. 5 is the supporting surface of coming before said the 7a 12, and next this supporting surface carries out such moving with bag bundle 4 along the direction of arrow 6, and promptly when mobile end, the distance that it moves from the bag bundle is slightly greater than the width of segment,

Fig. 6 is new cut-out when beginning, and also sheet 8 enters into the situation of bag bundle 4.

According to Fig. 7, after once cutting off, can not swing whole cutting anvil 11, but only parts 11b is moved horizontally it along the swing of arrow 18 directions or by a drive unit 23 along arrow 21 directions by a drive unit 2, said drive unit 22 for example is made of a cylinder-piston system, and said drive unit 23 can be made of a cylinder-piston system too.After the segment 7 of cutting was transported, this segment was supported by a spigot surface 24, and then, the direction that the parts 11b another mistake of cutting anvil 11 arrow 18 or 21 is moved back into its initial position.

The motion sequence of blade 8, cutting anvil 11 and supporting surface 12 will guarantee that blade 8 can enter in the bag bundle 4 easily, because tobacco is squeezed in cutting off passage and segment 7 supported and guiding in cutting and ensuing downward conveying moving process.

What Fig. 8 showed is a kind of vertical structure of cutting off that is used for realizing.For this reason, a blade 8 is moved by being directed downwards of arrow 9 so that finish the cut-out of once passing the bag of not retouching out the bundle (position 4 among Fig. 1) that is introduced on the conveyer belt 1 by the drive unit of cylinder-piston system 26 forms, and next move up in opposite direction, do not have reinforcement 10 (Fig. 1) at this blade of sweeping 8, yet this reinforcement can be arranged yet.Be used for making the drive unit 22 of cutting anvil 11 swings to constitute by cylinder-piston system too.27 expressions be a frame, the

drive unit

22 and 26 that is used to cut anvil or blade is installed to this frame.After each cut-out of blade 8, the piston in drive unit 22 cylinders moves up along corresponding arrow 28.It is upwards moving that piston rod 29 drives a bar 31, cuts anvil 11 like this and just swing around axle 30 in mode shown in Figure 9.In this position shown in Figure 9, the segment 7 from 4 cutting-outs of bag bundle that does not show can arrive on the band conveyor 16 and can be transported further processing.After this, piston rod 29 moves down against the direction of arrow 28, and bar 31 and cutting anvil 11 are just put again and got back to it on the cutting position shown in Fig. 8 like this.

What Figure 10 described is another kind of form of the present invention, and to lower swing, and the parts 11a on opposite maintains static at movable member 11b of this cutting anvil 11.11c represents still cuts a notch in the anvil 11, and blade 8 is not brought on conveyer belt passing the tobacco bag bundle of not describing out, but push away by the direction of a push rod that is not described 36 upper edge arrows 6 on the plane.In cutting the fixed guide face of slight bending inclined-plane 37 forms is arranged below the anvil, simultaneously be provided with on the inclined-plane driven, through the band conveyors 16 of

roller

13 and 14 guiding.

The movable member 11b of cutting anvil 11 has a support plate 39 that is fixed on two rectangular tubes 38, and this support plate is fixed on the end of band steel 41.Band steel 41 and support plate 39 therefore can be around 42 swings of a balance staff.A pneumatic manipulation cylinder 40 can be used as the dynamical element of swing, and its piston rod 43 that is promoted by invisible piston is to be connected in band steel 41 centres with a connecting rod 44.At piston rod 43 when the direction of arrow 46 moves, piston rod 43, connecting rod 44,

band steel

41 and 39 directions along arrow 47 of support plate move, the cutting position of describing from solid line moves on to the position that with dashed lines is depicted, and on this position, the segment of having cut off (not depicting) is cast.The advantage of this form of implementation is that the segment of having cut off just can be fully by the gravity of himself and promptly arrived on the band conveyor 16, and they are transported this band conveyor so that further processing.

After transporting, the parts 11b of cutting anvil 11 comes back to its initial position by piston rod 43 skew in the opposite direction, and on this position, blade 8 can be proceeded cutting.

Movable supporting surface 12 is positioned in the centre of band steel 41, and it has a lower knuckle 12a towards the careless segment direction of giving up smoking to be cut as feature.
