The utility model adopts novel swinging briar dressing mode and the poking fork is capable of extending between the two rewinding rollers with the farthest extending range reaching the narrowest crack between the two rewinding rollers; thereby, even with very small diameter, the drum can still be poked out from between the two rewinding rollers.

Description

Rewinding machine falls to managing poking device automatically

Technical field

The utility model relates to and falls to managing poking device automatically in the structure of rewinding machine, particularly rewinding machine.

Background technology

Rewinding machine is mainly used in produces the drum product, as toilet roll etc.Rewinding machine all has two rewind roll side by side, and the tube seat that is used to place the core pipe, and its basic functional principle is: at first the core pipe is lowered between two rewind roll in tube seat, this process is called to fall pipe; Drive the core pipes by two rewind roll then and rotate, the film like material for the treatment of rewinding such as paper etc. are rolled twist on the core pipe, form reel; After the diameter of reel reaches requirement, again reel to be transferred between two rewind roll, this process is called material toggling, so far finishes the rewinding operation.In prior art, the action of the material toggling of rewinding machine all is the mode that adopts horizontal sliding, that is relies on a sliding part that reel is released between two rewind roll.Owing to cave in the position between two rewind roll, so the mode of this horizontal sliding material toggling is difficult to the reel that diameter is less and releases between two rewind roll.For this reason, ZL01209701.2 number, are called the utility model patent of " a kind of rewinding machine with automatic core tube feeding device " and have done improvement, its material toggling action is what to be finished by the push rod in one slide-plate the place ahead, but this push rod is also rotation in horizontal sliding, drive reel with this and roll, make that push rod is easier reel is released between two rewind roll.But this patent can not solve foregoing problems very effectively, when the diameter of made reel hour, push rod still is difficult to reel is released, even the generation reel is stuck in the situation between slide plate and the rewind roll, and when the diameter of made reel more hour, even push rod touches less than reel at all, and this has just limited the minimum diameter that rewinding machine can be made reel.On the other hand, this patent must adopt two cover actuating units, realizes the slip of slide plate and the rotation of push rod respectively, and mechanism's complexity has increased the manufacturing cost of rewinding machine.

Summary of the invention

The purpose of this utility model provides and a kind ofly can reliably the minor diameter reel be fallen to managing poking device automatically from the rewinding machine of transfering between two rewind roll.

The utility model is achieved in that rewinding machine falls to managing poking device automatically and comprises two rewind roll side by side, and the tube seat that is used to deposit the core pipe, especially, the mouth of pipe below that falls in tube seat is provided with the shift fork that can swing up and down, shift fork extends between two rewind roll, the condition that the amplitude of fluctuation of shift fork satisfies is: when shift fork is rocked to end position downwards, on serving as reasons down towards rewind roll bevelled form, when shift fork is swung from bottom to top through two rewind roll between, with this with reel from dialling between two rewind roll; With the coaxial projection that is fixed with of shift fork, projection and shift fork at the phase angle relationship on the swinging plane are: when shift fork is rocked to end position downwards, projection swings to the fall position of the mouth of pipe of tube seat, block the tube seat mouth of pipe that falls with this, when shift fork upwards was rocked to end position, projection swung to and departs from the fall position of the mouth of pipe of tube seat fully.Principle of work of the present utility model is such: at initial condition, shift fork is positioned at the position that is rocked to the limit downwards, and this moment, projection was just blocked the mouth of pipe that falls of tube seat, and the core Guan Buhui that leaves in the tube seat falls; When falling to managing, shift fork upwards is rocked to end position, this moment, projection just departed from the mouth of pipe that falls of tube seat fully, so the core pipe falls on the shift fork, the and then downward backswing of shift fork, the core pipe that the while projection will fall on the shift fork ejects, when shift fork to the bottom to the utmost point during extreme position, the core pipe just tumbles between two rewind roll along shift fork, and projection was got back to once more and blocked the fall position of the mouth of pipe of tube seat this moment, has guaranteed that the every swing of shift fork once has only a core pipe to fall; Fall behind the pipe, two rewind roll drive the core pipes and rotate, and the film like material for the treatment of rewinding such as paper etc. are rolled twist on the core pipe, form reel; After the diameter of reel reached requirement, two rewind roll stopped operating, and shift fork is upwards swung once more and reel is transferred between two rewind roll, finished the material toggling action; After shift fork upwards was rocked to end position, projection departed from the mouth of pipe that falls of tube seat once more, so there is a core pipe to fall on the shift fork again, so cycle event just can constantly finish the action of pipe and material toggling automatically.This shows, the utility model has been discarded the design philosophy that adopts horizontal sliding material toggling mode in the prior art fully, use brand new swing material toggling mode instead, because shift fork can extend between two rewind roll, and the longest crack position that extends distance minimum between two rewind roll, even therefore the diameter of reel is very little, also can reliably reel be transferred between two rewind roll.

The utility model has the advantages that the material toggling reliable in action, make rewinding machine rewinding go out the littler reel of diameter, expanded the fertile product specification kind of rewinding machine, in addition, the utility model only needs can drive shift fork and projection action simultaneously once the cover actuating unit, simple in structure, help reducing the manufacturing cost of rewinding machine.

The specific embodiment

Referring to Fig. 1, rewinding machine falls to managing poking device automatically and comprises two rewind roll 1,2 side by side, and the tube seat that is used to deposit the core pipe.The same with existing rewinding machine, tube seat comprises side plate 3, header board 4 and back plate 5, regulate the axial location of the whole core pipe of adjustable positions of side plate 3, regulating handle 6 can be adjusted the distance between the forward and backward

plate

4,5, the bottom of tube seat is the mouth of pipe that falls, the mouth of pipe place that falls is provided with regulating block 7, and plate 5 can be adjusted up and down behind regulating block 7 and the tube seat.Tube seat fall the mouth of pipe below be provided with the shift fork 8 that can swing up and down, the balance staff 9 of shift fork can be supported on the frame of rewinding machine.Along the axial direction of balance staff 9 a plurality of shift forks 8 that can be arranged side by side.Shift fork 8 extends between two rewind roll 1,2.Shift fork 8 among Fig. 1 is in the position that is rocked to the limit downwards, forms from top to bottom towards rewind roll bevelled form.Can be when shift fork 8 is upwards swung with reel 10 from dialling between two rewind roll.Present embodiment relies on cylinder 11 to drive shift fork 8 swings, when the piston rod of cylinder 11 is flexible, drives shift fork 8 by connecting rod 12 and swings up and down.In addition, also can adopt other routine techniques to realize the swing of shift fork 8, for example replace cylinder 11, rely on electromagnet that adhesive, the repulsive interaction of connecting rod are driven the shift fork swing with electromagnet.With the shift fork 8 coaxial projections 13 that are fixed with, projection 13 can be with shift fork 8 swings.Projection 13 with shift fork 8 at the phase angle relationship on the swinging plane is: when shift fork 8 is rocked to end position downwards, projection 13 swings to can block the fall position of the mouth of pipe of tube seat, that is state shown in Figure 1, when shift fork 8 upwards is rocked to end position, projection 13 swings to and departs from tube seat the fall position of the mouth of pipe that is state shown in Figure 2 fully.Present embodiment directly is fixed on projection 13 on the shift fork 8, in addition, also can projection 13 balance staffs 9 direct and shift fork are fixing, but must make the projection 13 and the phase relation of shift fork 8 satisfy aforementioned requirement, and projection 13 has the mouth of pipe that falls that enough height can be blocked tube seat.The principle of work of present embodiment is as follows: under initial condition shown in Figure 1, shift fork 8 is positioned at the position that is rocked to the limit downwards, projection 13 is just blocked the mouth of pipe that falls of tube seat, and the core pipe 14 that leaves in the tube seat can not fall, and still do not have reel 10 between two rewind roll this moment; When falling to managing, cylinder 11 drives shift fork 8 and upwards is rocked to end position, as shown in Figure 2, this moment, projection 13 just departed from the mouth of pipe that falls of tube seat fully, core pipe 14 falls on the shift fork 8, and then cylinder 11 drives shift fork 8 downward backswing, in the backswing process, the core pipe 14 that projection 13 will fall on the shift fork ejects, when shift fork backswing during to end position shown in Figure 1, core pipe 14 just tumbles between two rewind roll 1,2 along shift fork 8, and this moment, projection 13 was blocked the mouth of pipe that falls of tube seat once more, has guaranteed that shift fork 8 every swings once have only a core pipe to fall; Fall behind the pipe, two rewind roll 1,2 drive the core pipe by friction force and rotate, the film like material for the treatment of rewinding such as paper etc. are rolled to twist on the core pipe, form reel 10, the same with existing rewinding machine, all the time have a pressure roller 15 to be pressed on the reel 10 in rolling the process of volume, its effect is to guarantee between reel and two rewind roll enough friction force are arranged.After the diameter of reel 10 reaches requirement, two rewind roll 1,2 stop operating, and pressure roller 15 upwards returns back to original position under the drive of cylinder 16 simultaneously, and and then cylinder 11 drives shift fork 8 upwards swing once more, thereby reel 10 from transfering between two rewind roll 1,2, is finished the material toggling action; After shift fork 8 upwards was rocked to end position, projection 13 departed from the mouth of pipe that falls of tube seat once more, gets back to state shown in Figure 2, so there is a core pipe to fall on the shift fork again, so cycle event just can constantly finish the action of pipe and material toggling automatically.

As preferred forms, referring to Fig. 1, Fig. 3, the end that shift fork 8 stretches to rewind roll bends to circular-arc, and therein on rewind roll 1, the position relative with shift fork 8 is provided with all annular grooves 17, and the circular-arc position of shift fork 8 is hidden in this annular groove 17.The advantage of this structure is that the termination of shift fork 8 can extend the minimum crack position of distance between two rewind roll 1,2, thereby can transfer between two rewind roll by to greatest extent that diameter is very little reel.

As further improvement, as shown in Figure 1, the upper surface of the projection 13 of present embodiment is an arc surface, and the line of centers of arc surface overlaps with the axis of oscillation of shift fork 8, can make like this in projection 13 falls the process of the mouth of pipe through tube seats, the height of core pipe 14 that is bearing in the projection upper surface is constant all the time, thereby has avoided core pipe in the tube seat because of the vertical tremor that swings back and forth of projection.In addition, the projection 13 among Fig. 1 is precipitous wall towards an end side surface of rewind roll, and is more smooth and easy when so can make projection will fall to core pipe on the shift fork to eject.
