Relate to the prior art of making shaped blanks, comprise industrial practice, set up well, and be well known that it is very uneconomical.Because the difficulty that the blank non-linear shape is brought, the cutting of blank and/or the normally all or part of craft of stacking are finished.Make the effort of blank cutting and/or stacking operation automation cause the cost of equipment expenditure in the past, a series of independent machines have been installed thus successively to finish: feed operation; Cutting operation; Move the blank that cuts down; The blank that stacking cuts down.This known manufacturing is arranged and is needed a large amount of funds, needs the auxiliary of a large amount of dust free room, floor area and operator, and be easy to take place serious remodeling difficulty inherently.

Therefore, first purpose of the present invention provides a kind of equipment, and this equipment can cut arc film automatically and stack the film that cuts down.Another object of the present invention provides a kind of equipment, and this equipment can be continuously and need not manually be cut and stack the cutting forming blank of circular contour automatically, substantially.Another object of the present invention is a kind of method that is used for making and stacking automatically continuously the cutting forming blank of design.Realize above and other objects of the present invention by a kind of machine, this machine comprises: a loading bay; One cutting device; With one division bench board (indexingtable).

Therefore, the present invention relates to automatic cutting and stacking adapter that arc blank is used, comprising:

(a) loading bay, it can supply with the arc film of specified length to cutter sweep;

(b) one formed film cut into the device of blank;

(c) one stacks device, and it comprises that one has the index table and a base plate of the slide plate that adheres to.

In a preferred embodiment, feeding mechanism is by 12 operations of charging wheel, and the charging wheel is shifted the film of specified length onto cutter sweep.Cutter sweep 2 can show as the fixedly bed plate 21 that combines with the rotating knife 22 of cross motion.Angle between bed plate and the charging wheel line of centers should be adjustable, thinks that the radius of any selection obtains perpendicular cuts.Index table 33 has base plate 3, its by with the basic corresponding increment of the thickness of cutting forming blank to descend with the synchronous mode of the operation of cutter sweep.The base plate of the cutting blank heap that support to form can slippage on index table, is suitable for any purposes and/or processing like this.

Below with reference to accompanying drawing the present invention is described, wherein:

Fig. 1 is the planar view of expression according to automatic cutting of the present invention and stacking adapter;

Fig. 2 a; 2b; 2c; 2d; 2e and 2f are the section-drawing of the present invention about cutting and stacking adapter operation order.What Fig. 2 a represented is the starting position, and base plate 3 is empty.What Fig. 2 b represented is first blank that cuts down 41.Fig. 2 c represents is the blank that a pile of piling up on slide plate 31 and base plate cuts down.Fig. 2 d represents is to move the base plate that has the blank that a pile cuts down.Fig. 2 e represents is blank heap on the base plate after slide plate is removed.Fig. 2 f represents is the automatic stacking adapter of removing after the base plate that is loaded with the blank that a pile cuts down.

Describe and explain the present invention with particular reference to accompanying drawing.The loading bay 1 of Fig. 1 has a system, and this system is placed into the front of advancing of formed film in the cutter sweep by this way, promptly makes cutting will produce the blank of wishing size.Charging wheel 12 is pushed into cutter sweep along guide piece 11 with the film of specified length.Pressure roller 13 is pressed in formed film on the charging wheel, skids to prevent, and skids to change the predetermined angular of blank.Every kind of radius should use independent guide piece.

Cutter sweep 2 can show as any type of cutting mechanism that plastic film is cut in known can being fit to usually automatically.Cutting mechanism generally includes fixedly a bed plate and a cutter, plug-in strip for example, or rotating knife preferably, and this cutter moves to shear along base plate.In a preferred embodiment, can use the fixedly bed plate 21 that combines with the rotating knife 22 of cross motion.Comprise the fixedly position, particularly rotation direction of the cutter unit of bed plate and secondary cutter, can by obtainable any suitable mechanism usually for example vertical axis be independent of loading bay and relatively loading bay adjust.Angle between bed plate and the charging wheel line of centers is adjustable, thereby allows can both carry out perpendicular cuts to all radiuses.In one of cutter unit preferred the adjustment, be 1 to 8 meter formed film for radius, the angle ranging from 0 ° to about 18 °.In other words, cutting angle should make cutting can produce perpendicular to the cutting that the profile film edge is arranged.Charging wheel 12 is positioned as close to bed plate in application, i.e. the outlet limit of loading bay 1.

After having the profile film to cut down, blank is collected on the base plate 3.In more detail, there is the profile film to pass cutter sweep and arrives base plate, up to reaching selected length to be cut by means of slide plate 31.Cutting cuts off blank from there being the profile film to divide.The blank that cuts down then is stacked on the base plate.The height of the blank that gets off for Cutting Control to be avoiding blocking new blank, and index table 33 is to descend with the synchronous mode of cutter sweep.The calibration increment corresponds essentially to the thickness of the film of cutting forming.Increment can be corresponding to the thickness of the blank of one or more cutting formings.Have found that the calibration increment corresponding to the blank thickness of two to ten times cutting forming is favourable.

Slide plate 31 is used to overcome the diff-H between bed plate 21 and the base plate 3.Slide plate is for good and all attached on the index table 33.The top of index table has roller 32, so that base plate, the manipulation of base plate that particularly is stacked with the blank that cuts down is easier.When moving when having the base plate of blank, rest on the motion that a bit of blank on the base plate is followed base plate, after leaving slide plate, to form vertical blank heap.

The existing base plate that is loaded with the blank heap that cuts down just is the application on laminated yarn or may sequenced any purposes gets ready.

Here very favorable loading bay can show as the treatment bench of the common unsettled European patent application EP-A-97870135.7 that submits to according on September 12nd, 1997.Can preferably show as plasticizing polyvinylbutyral interlayer film by the formed film that the automatic cutting here and stacking adapter are handled.This film can be by known manufacturing technology, preferably according to forming as two umbrella shaping machine technology of describing in EP-A-0.685.316.
