Abstract

Web, drawn intermittently from roll A, e.g. by packaging apparatus D, is formed into a U-shape in suction device C, which includes a loop sensor 3a controlling a device i which feeds web to device C. The vertical extent of the U-shape is thus kept constant and web tension downstream of device G is controlled. Device C comprises a rectangular-section, open-topped box, suction being applied at port 2b. The distance between the box side walls, i.e. those which extend parallel with the web, is adjustable to match the width of the web. The packaging apparatus is stopped when a second loop sensor 3b detects an abnormally small U-shape.

But, in this apparatus for supplying web in the past, nutted rod is to swing with the cooresponding speed of the rate of delivery at intermittence of bag material, therefore, especially when bag material at high speed is intermittently sent, because the weight of this nutted rod and idler roller during the nutted rod swing, inertia works, therefore can swing to above necessary angle, for the bag material of thereupon sending, servo-actuated can take place and lag behind, simultaneously, because along with the bag material is sent, it is got over by frame by some driven idler rollers and guiding roller, therefore, and when especially bag material at high speed is sent off and on, then the phenomenon that the bag material is sent necessary above length can take place because of the revolution inertia of many driven vollers, as a result, it is loose that the bag material takes place easily, and making does not have tension force fully on bag material, be moved on the Width vertical with bag material transport direction, on the bag material, indicate symbol, when joining the pattern of bag material, the low problem of accuracy of positioning can take place according to this symbol location every a determining deviation.
Furtherly, because many driven vollers, make the extreme sweep of bag material many, thereby the body bone is arranged and the occasion of hardening in bag material material, existence is in bad order to the coiling of driven voller, can not give the problem of bag material integral body, but also exist the bag material frame pretty troublesome problem of operation on many driven vollers more with homogeneous tension force.
The present invention puts forward in view of the existing problem of conventional art, the present invention does not pass through coasting body, one side tails off extreme sweep, one side makes bag material frame more, often give tension force equably, bag material can not be moved at Width, the packaging and filling machinery that can form the bag that does not have offset is provided, with this as purpose of the present invention.
In order to solve above-mentioned problem, the technological means that packaging and filling machinery of the present invention is taked is: by the intermitten of delivering mechanism, the bag material of being supplied with by bag material cylinder is sent with preseting length, send the path midway at this, setting is with sending action the intermittence of this bag material, sending mechanism in advance from what bag material cylinder was pulled out bag material, attract the bag material to make the attraction mechanism of its loose one-tenth U font in the above-mentioned downstream configuration of sending mechanism in advance, according to this loose length of U font bag material and variation, drive controlling is sent mechanism in advance; It is characterized in that: make respectively relative configuration of spigot surface with the Width both side edges contact of U font bag material, to form tubular by the bag material that bag material cylinder is supplied with by tube shaped object one side simultaneously, one side hangs down it, by starting of horizontal sealer, the bag material is sealed, forms bag at Width, packed article is filled in this bag, delivering mechanism is configured in the downstream of a shaped object.
Again, above-mentioned attraction mechanism is offered peristome that band is embedded, is offered the case shape induction chamber that attracts mouthful in the other end and detect the detector that embeds the loose length of the U font bag material in the induction chamber from peristome and form by face at one end, output according to this detector, drive controlling is sent mechanism in advance, make the loose length of U font bag material keep certain, simultaneously, preferably make in the induction chamber vis-a-vis spigot surface form roughly width dimensions identical distance with the bag material.
If according to above-mentioned technological means, along with the action that attracts mechanism, by attracting the bag material, making it loose is the U font, gives the bag material with certain force of strain, send the intermittence that is accompanied by bag material, U font bag material is along vis-a-vis spigot surface, is positioned and pulls out at its Width, simultaneously, loose length variations by this U font bag material comes drive controlling to send mechanism in advance, makes the loose length of U font bag material keep certain.
Below, with reference to accompanying drawing, one embodiment of the invention are described.
Fig. 1 is the front elevation of expression one embodiment of the invention, and the induction chamber vertical profile is represented; Fig. 2 is along the part amplification view of Fig. 1 (II)-(II) line, and biopsy cavity marker devices is represented.
This embodiment as shown in Figure 1, tube shaped object D1 from bag material cylinder A to packaging and filling machinery D sends on the B of path, the C of attraction mechanism that setting is made up of induction chamber 2 and detector 3, to be positioned at the downstream of shaped object D1 is located at and the bag of the packaging and filling machinery D position vis-a-vis, surface with cylinder D2 as the band of sending of delivering mechanism E, by the intermitten of this delivering mechanism E, bag material W is sent preseting length towards the bag material W pull-out direction of being made up of for example outlet roller or the like of sending mechanism 1 in advance.
Induction chamber forms the case shape of lengthwise by some flat plate separation, is opening above it, form along each comfortable vertical section of transport direction pair of openings edge vis-a-vis of this peristome 2a circular-arc, along sending path B frame more at this two circular arcs edge 2a 1, 2a 1Between a bag material W embed into the U font.
Below this induction chamber 2, offer and attract a mouthful 2b, the inside that makes induction chamber 2 by this attractions mouthful 2b be arranged on that induction chamber is 2 exterior, the big attraction source 2c of for example multi blade fan or the like attraction flow connects.
This attraction mouthful 2b is arranged in around it ventilation body 2b of sponge for example etc., and is outstanding to the inside of induction chamber 2, by being horizontally set with net 2b in the above 2, prevent from bag material W suck is attracted in mouthful 2b, simultaneously,, make that it also can aspirated air even when sucking bag material W because of misoperation; And, by adjusting the air outlet 2c that for example attracts source 2c 1Aperture area, make the width dimensions conversion that it can corresponding bag material W, adjust attractive force.
In addition, the direction vertical with the transport direction of induction chamber 2 a pair of spigot surface 2d, 2d vis-a-vis along to the transport direction downstream, forms respectively gradually to induction chamber 2 inner outstanding rake 2d 1, 2d 1, from these rakes 2d 1, 2d 1, the inner width size W that makes the downstream is roughly the same with the width dimensions of bag material W and since make each spigot surface 2d, 2d respectively with the U font bag material W that pulls out from bag material cylinder A 1Width both side edges W2, W2 the contact, thereby can correct the skew of bag material W at Width, simultaneously, move at the Width of bag material W and to support two flat boards that constitute spigot surface 2d, 2d or either party's flat board freely, for example adjust means 2d by manual handle 2, two spigot surface 2d, 2d or a side's side is moved, make it can be corresponding to the conversion of the width dimensions of bag material W.
To the side that attracts mouthful 2b, detector 3 is set from above-mentioned peristome 2a, it can detect the relaxed length that is embedded in the U font bag material W1 in the induction chamber 2, controls the above-mentioned action of sending mechanism 1 in advance.
This detector 3 is in the present embodiment occasion, is positioned at the pars intermedia of upper and lower sides of the spigot surface 2e in transport direction downstream, and two detectors separate appropriate intervals at above-below direction, in the face of U font bag material W 1Bury underground, as U font bag material W 1Lower end position along with the intermitten of above-mentioned delivering mechanism E to than desired location also the direction of top move and be in when not detecting, lower detector 3a makes and sends mechanism 1 in advance and begin action; Simultaneously, when to than desired location also the direction of below move and be in when detecting, it stops action that to send mechanism 1 in advance; And the detector 3b of top detects as the anomalous behavior that the action that makes delivering mechanism E when not detecting stops.
In addition, 4 is sensors of detected symbol among the figure, and F, F are horizontal sealers.
Apparatus for supplying web is inhaled air in this induction chamber 2 from attracting a mouthful 2b, and negative pressure takes place thereupon, and bag material W is inhaled into induction chamber 2 inside and is the U font, gives bag material W with certain force of strain.
In this state, because the intermitten of delivering mechanism E, bag material W is drawn out to the transport direction downstream with preseting length, is embedded in the U font bag material W in the induction chamber 2 thereupon 1Lower end position be moved upward, relaxed length shoals, then lower detector detects this situation, makes to send mechanism 1 in advance and begin action, a bag material W3 who pulls out from bag material cylinder A is sent to induction chamber 2 sides, this U font bag material W 1Lower end position move down, relaxed length deepens gradually.
And, U font bag material W 1Relaxed length reach lower detector 3a, this detector 3a detects this state, and the action of sending mechanism 1 is in advance stopped, and makes U font bag material W 1Relaxed length keep certain.
After this, whenever delivering mechanism E intermitten, above-mentioned action repeats.
In addition, the structure of above-mentioned induction chamber 2 is not limited to schematic structure, for example to two relative circular arc edge 2a of transport direction 1, 2a 1By diagram is to form at same height and position, but also can form the circular arc edge 2a of transport direction upstream side 1Circular arc 2a than the downstream 1The position low, become easily the side 2e and the U font bag material W in while downstream by the introducing to induction chamber 2 in of sending the bag material W that mechanism 1 supplies with in advance like this 1Area of contact broaden, friction increases, and prevents U font bag material W 1Get ahead, utilize as drg.
The present invention is owing to said structure, so following advantage is arranged.
1. along with attracting mechanism action, it is the U font that the suction bag material makes it lax, give bag material certain tension force, along with send the intermittence of bag material, U font bag material is located and is drawn out along spigot surface direction vis-a-vis, simultaneously, the relaxed length of this U font bag material changes, mechanism action is sent in control in advance, it is certain that the relaxed length of U font bag material keeps, so can one side not make extreme bent part few by coasting body, one side makes bag material frame more, give the often tension force of homogeneous, it can not be moved at bag material width.
Therefore, more compared with the in the past device that gives tension force by frame with, a bag material many by the coasting bodies such as nutted rod and some driven vollers, extreme sweep, even apparatus of the present invention particularly bag material are interrupted at a high speed to send and can be prevented fully that also bag material from the relaxation of tension force taking place not have fully, therefore, the movement of width can not take place in the bag material, and in bag material figure case occasion, the location Precision is improved, and simultaneously, the occasion of hardening even bag material material has the body bone also can give bag material integral body with homogeneous tension force, and it is also simple that bag material frame is got over operation.
