Description

The machine of production cardboard tube etc. has the cutter sweep that cuts the certain-length pipeline section

The present invention is with relevant with the machine of making pipe by usefulness list two or many overlapped staggered shape belts in the shape of a spiral of coiled on axle, have a wind continuously band coiled one spirality of the list on axle and pipe that above-mentioned material is made constantly advances and one the swinging tube cutting mechanism be housed and be provided with along the cutter sweep of a traverse motion of pipe direction of advance, when pipe advances, above-mentioned pipe is cut into the pipeline section of certain-length.

These machines generally are used for paper-making industry to produce pipe or to be called hardboard tube core or analog, and one deck paper is around thereon to produce reel subsequently.Also find to have similar application in other departments, for example must the plastic sheeting of strip material such as industry or family expenses, the metallic film base material that is used to pack etc. on the tubular core to produce reel.Similarly pipe also is used for producing the particularly container of food industry of solid or fluid product.

The machine of the type of saying is for example at italian patent No1 at the beginning, 204, institute is illustrated in 029, but only to be used to cut the device of pipe relevant with the machine exit place, in this known machine, cutting member is made up of the round cutter of little quality, when pipe is prepared cutting, cutting member enters axial and gyration with regard to resting on the revolution of self axis and the pipe that advances and by contact with pipe self, in other words, these cutting members are assembled on respective support arms and can freely turn round and stall.

In order to reach more effectively cutting, particularly when thickness of pipe wall, in some cases, adopted two round cutting-off tools to link to each other with motor, when cutting knife need cut pipe, these motor just make cutting knife make cutting movement, above-mentioned scheme has improved manufacturing cost and has increased the quality of device, must be reciprocating continuously because the cutting mechanism of revolution cutting member is housed along the direction of advance of production pipe, reduce to minimum so wish quality, so the inertia force that produces during the cutting mechanism traverse motion just reduces also.

The purpose of this invention is to provide a kind of machine that begins type described in the literary composition, can more effective cutting pipe for the cutting movement that makes cutting member, thereby having the cramped construction of simple and limited quality, cutting member also reduced machine manufacturing and maintenance cost to reduce its inertia force.

For this professional those of ordinary skill, when reading hereinafter, all purposes and the advantage that begins described the sort of machine just had clear understanding, it is characterized in that cutter sweep links to each other with the parts that drive the revolution cutter sweep, thereby pass to gyration of laterally back and forth doing more physical exercises and causing of above-mentioned revolution cutter sweep by cutting mechanism, thereby needn't provide independent driver to cutting member, otherwise can increase additional cost and weight, also inconvenient from safeguarding.

In the embodiment of a reality, obtain the gyration of cutter sweep for traverse motion by cutting mechanism, be provided with a belt or similar deflection part (or flexible piece) and link two fixing points in the above-mentioned machine construction, this point of contact be positioned at outside the stroke of cutting mechanism and with respect to one of the direction of advance of pipe preceding, one after, link the part of deflection part between two points of fixed structure round one by cutting mechanism with the belt pulley running, belt pulley is movably linked rotating cutter sweep, carry out cutting by a reciprocal transverse movement and when mobile when cutting mechanism like this, advance at the same rate and when having cut, get back to original position at every turn with the pipe in being shaped, because the effect of cutting mechanism motion, the deflection part rotates belt pulley, and this belt pulley passes to cutting member to its rotation again.

Above-mentioned deflection part can be to link an opening flex member on the machine construction with its two ends, but this flex member also can form by the belt of a sealing, wherein only used one section belt being delimited by 2 that link fixed structure.

The further feature of machine of the present invention and embodiment are by shown in the appended dependent claims.

The traverse motion of cutting mechanism can be drawn by the movable binding that fetches self-driven device always, this driver drives is twined the system that list forms pipe and pipe is advanced, but in a special most preferred embodiment, this cutting mechanism is driven by a Standalone Drives that provide for oneself and that controlled by central authorities' (control) device, these central authorities (control) device also is used for controlling the driver of being responsible for carrying strip material, be used for the strip material spirally-wound and the formed thereby pipe is advanced, so just might be when carrying out cutting operation, cutting mechanism is realized best motion with respect to the forward travel of pipe, and this can narrate hereinafter in more detail.

Can more easily understand the present invention from specification and accompanying drawing, accompanying drawing illustrates a non-limiting example of the present invention.

Two

swing arms

59 and 61 each

comfortable point

57 and 58 are pivot and rotate on cutting mechanism 33, each swing arm has cutter sweep with the form of

turning circle cutter

63 and 65 at the arm end,

label

67 and 69 two of expressions each have the backplate of perforation 67A and 69A revolution cutter, and lubricated felt then is inserted in 67A and the 69A hole.

Swing arm 59 with 61 by connecting together with the connecting rod 71 that arm 59 is connected with 61 with 75 places at pin joint 73 respectively.Like this,

arm

59 and 61 is dynamic interconnection, the result, and this two arm is swung simultaneously by the effect of a single hydraulic cylinder and actuator piston 77, and above-mentioned hydraulic cylinder is linked planker 87 at point 79 places, and bar 80 then is hinged on the extension 59A of swing arm 59 at point 81 places.The extension 5A of swing arm 59 then links to each other with machine construction 45 all-in-one-piece cam type surfaces 85 interactional driven pulleys 83.This cam type surface 85 has one to be parallel to therefore first also just parallel with the axle 1 axis direction straight line portion 85A of pipe T direction of advance; One second ramp portion 85B links the 3rd parallel with it straight line portion 85C to the first straight line portion 85A, and one the 4th ramp portion 85D partly links a last straight line portion 85E with 85A and 85C partial parallel to 85D, and 85A and 85E part are then roughly in same plane.

The running of cutting mechanism 5 is as mentioned below:

When winding mechanism 5 band shapes material N coiled one spirals and when pipe T in the shaping is advanced, cutting mechanism 33 is in standby position (dot among Fig. 1 and illustrate with 33A) within it, wherein cutting mechanism 33 is in the left hand end (asking for an interview Fig. 1) of its stroke, in this position, driven pulley 83 is positioned at the below of the 85a part of cam type surface 85.When cutting mechanism 33 is in standby position, driver 77 is positioned at the position that makes cutter 63 and opened in 65 minutes, so cutter just do not contact with pipe T, and driven pulley 83 is just removed from profile 85A.

In the outlet side (not shown) of machine the sensor of an optics or other type is arranged, have one and can detect the position adjustable that the initiating terminal of forming tube arrives.In Fig. 1, but sensor is only represented as representing for the information of understanding and not shown actual present position with S.Just make sensor send a signal in case detect the arrival of pipe, this signal makes bar 80 stretch out and start driver 53 from driver 77, driver 53 reaches the speed of service selected and control from beginning static moving to, by rack-and-pinion to 49 and 47, cutting mechanism 33 just obtain one be shaped by equaling of determining of motor 19 rotating speed ultimate analysis in the pace of pipe pace.The pace of CCU control driver 19,53 of representing with label 90 among Fig. 1 and the pace of the such pipe of sensor S and cutting mechanism 33 is as indicated above to be synchronous.

In the time of with driver 53 startings, actuator piston 77 also begins to move and the section of the stretching out 59a of swing arm 59 is swung along clockwise direction, and it causes

arm

59 and 61 mutual relative swings, and consequently

cutter

63,65 is approaching mutually thereupon.Because initially be close to the existence of the 85A driven pulley partly of cam type surface 85, the swing of above-mentioned arm is each self-reversal.(see figure 1) when cutting mechanism 33 beginnings are advanced from left to right, driven pulley 83 is along profile 85 operations, it partly moves on to 85B part and then moves on to the 85C part of higher position from 85A, take place above-mentioned when mobile, because cylinder and actuator piston 77 all are under the pressure, driven pulley 83 keeps contacting with cam type surface 85, and the shape of cam type surface 85 makes

swing arm

59 and 61 swings, thereby it is relative approaching that

cutter

63 and 65 is taken place thereupon.Make when driven pulley 83 is in this position 85C the position of the 85C part of cam type surface 85, and

cutter

63 and 65 is pressed to preceding inlet pipe.The 85A of cam type surface 85, the length of 85B part causes the lateral velocity of having only when cutting mechanism 33 forward to reach when being substantially equal to the pace that needs cutting pipe T, and driven pulley 83 just arrives the 85C part, and like this,

cutter

63 and 65 just carries out perfect cutting to managing T.

The length of the 85C of cam type surface 85 part should be definite like this, and promptly this length can make pipe T realize complete cutting and also can adapt to when the vary in diameter of the pipe of production of machinery and need not change.The vary in diameter that adapts to forming tube can realize that for this purpose, driven pulley has an eccentric axis by the position that changes driven pulley 83, and the position of cutter is also regulated by elongation and shortening bar 71.

When pipe downcuts, cutting mechanism 33 is parked on the LAP with regard to deceleration, and at this moment, driven pulley 83 partly moves in the 85D of cam type surface 85 part and 85E.When advancing above stroke, cylinder and piston system 77 make

arm

59,61 be the rightabout swing,

cutter

63 and 65 takes place thereupon drop back from pipe T.Promptly detect when arriving the maximum position (the label 33B that is represented by dotted lines among Fig. 1) that advances by a position sensor (not shown), reverse by motor 53, this cutting mechanism 33 in the opposite direction quickens and gets back to its original standby position, in backstroke, driven pulley 83 does not interact with cam type surface 85, because driven pulley 83 is recalled by the effect of cylinder and

piston

77,63,65 maintenances of cutter simultaneously separate with the pipe that continues to advance with its speed of production.

Be provided a linear movement by the then

round cutter

63 and 65 of method hereinafter described and change the cutting movement of coming by cutting mechanism 33.

At two points 93 and 95 places one deflection part, 97 (see figure 1)s are linked on the fixed structure of machine, shown in example in, fasten a little and 93 be placed in the mechanism 36, fasten a little and 95 then be placed on the post 96, fastening a little of flex member 97 93 and 95 lays respectively at stroke the place ahead and the rear of cutting mechanism 33 with respect to the direction of advance of forming tube, especially please see Figure 3 and Fig. 4, flex member 97 around two by cutting mechanism 33 with the Returning wheel 98 that freely turns round and 99 and move.

Wheel

98,99 the mutual almost parallel of axis and perpendicular to the direction of advance of pipe T, therefore just perpendicular with the axis of axle 1.As shown in Figure 4 between two wheels that stagger mutually 98 and 99 deflection part 97 form a closed-loop path, the axis of the parallel axle 1 of the axis of above-mentioned cone pulley 101 around multistep cone pulley 101 runnings.

Shown in example in, groove 101A, 101B and 101C that multistep cone pulley 101 has three selective diameters to increase gradually.In Fig. 3, deflection part 97 is to turn round in the groove 101B of intermediate diameters.Will understand hereinafter, the multistep cone pulley that adopts the different-diameter groove is under the speed of identical pipe T pace and cutting mechanism 33, allow to change the rotating speed of

cutter

63 and 65, the rotating speed of cutter is such selections, makes its circumferential speed (peripheral speed) be equal to or greater than the circumferential speed (peripheral speed) of pipe T.

When cutting, the opposite side sleeve pipe in the pipe T among cutter and Fig. 1 shown in the label 102 interacts, and this operates in the italian patent No.1204029 that is quoted detailed description.

This multistep cone pulley 101 is installed on one 103, and this axle is also fixed a belt wheel 105 with key, and belt 107 is around belt wheel 105 runnings.Pass to

round cutter

63 and 65 with the torque of 107 belt wheels 105.For this purpose, this belt 107 is not only around belt wheel 105 but also around two coaxial and all-in-one-piece belt wheel 106,107 runnings with

cutter

63,65, and around by cutting mechanism 33 with the guide wheel that freely rotates 108 and 109 and turn round.

When cutting mechanism 33 under the effect of motor 53, when moving by the direction shown in the arrow 33, arrangement as indicated above, a deflection part (being the level and smooth open band of a circle cross section in the example shown) that fastenes on two fixing points of machine construction makes multistep cone pulley 101 revolutions, make belt wheel 105 revolutions thereupon, therefore also just make round

cutter

63 and 65 revolutions.Very clear, the gyratory directions of circle cutter depends on the direction of advance of cutting mechanism 33, and when cutting mechanism 33 has arrived the final position of its stroke and restarts when back mobile, above-mentioned cutter are counter-rotating just.When cutting mechanism 33 backhauls, the revolution of above-mentioned round cutter is inoperative and invalid, because above-mentioned cutter are dropped back from pipe T by method mentioned above already.
