Description

The star conveyer of container

The present invention relates to a kind of star conveyer (Transportstern) by the described container of claim 1 preamble.

Known a kind of this type of star conveyer, wherein, manipulator viscoelasticity plastic manufacturing, and be designed to integral type double lever (DE-GM 29501897.6).This possible elastic bending of manipulator, be needed on the one hand in order when catching container, to produce necessary gripping power, and also be the part that struts that is designed to rotating cam in order to make on the other hand, combine with incision-like groove on bearing surface, stably be self-locking in make position.Because what make is the one-piece plastic molded part, so the manipulator productive costs of known star conveyer is very low.Disadvantageously, their elasticity attenuation As time goes on, and because deformability is limited, so they can only be used for the little container diameter of completely specified error.

The objective of the invention is,, take simple measure for the star conveyer of the above-mentioned type, service life of prolonged mechanical hand significantly, and enlarge the diameter range of the container handling of wanting significantly.

Reach this purpose by the present invention by the feature described in claim 1 characteristic.

In pressing star conveyer of the present invention, manipulator itself or its parts needn't be out of shape when catching container.Distortion will be those elastic components, they can specific adaptation aspect long service life and big diameter range in its concrete application purpose.

Therefore, undoubtedly can be described by claim 2, be to have a bending rigidity with the part design of manipulator, so, elastic deformation and produce gripping power and finish by elastic component uniquely.

Other favourable improvement of the present invention are included in remaining dependent claims.

Below by means of the description of drawings embodiments of the invention.Wherein:

Fig. 1 star conveyer partial top view;

Fig. 2 presses the A-B section of Fig. 1;

The A-B section of the another kind of form of implementation of Fig. 3 star conveyer; And

Fig. 4 presses the Z of Fig. 3 to view.

Star conveyer 1 shown in Fig. 1 and 2 is used for upright the container of the bottle 2 on the delivery form.It is located at the inlet of bottle handler, and for example test machine enters the mouth, and has only represented the transport plane 14 and the transmission shaft 15 of star conveyer 1 in the drawings.

Star conveyer 1 has a pedestal 3, and it mainly is made up of two parallel annulus 16,17.These two

rings

16,17 have identical external diameter; Internal diameter but is different, wherein, on to encircle 16 internal diameter littler than the internal diameter of ring 17 down.These two are encircled 16,17 concentric arrangement, and couple together rigidly mutually by some paired pins 18 with circular cross sections along their circle distribution.Two screws of each pin 18 usefulness detachably are fixed between two

rings

16,17 one by one.

Last ring 16 side within it has manyly along circumference well-distributed hole, and these borehole jacks are on pin 19.Pin 19 itself is fixed on the end of many radial arms 20 of wheel hub 21, and wheel hub 21 is permanently connected with transmission shaft 15 rotations.By means of a plurality of hand operation fixing devices 22 that act on the ring 16, pedestal 3 detachably is clamped on the arm 20, and the line of centers of pedestal 3 and transmission shaft 15 are located with one heart.

A

manipulator

4,5 is housed on each pin 18 swingably.Two

manipulators

4,5 installing on the pin 18 that matches are designed to the pattern of double lever looking-glass symmetry, and have constituted a clamp jointly, and it can catch a bottle 2 by force-closed and shape sealing.

Each

manipulator

4,5 has two parts a and b, and they are for example made with high-strength rigid plastics or metal, and thereby itself has bending rigidity.Each

first parts

4a, 5a is designed to double lever, and they are end and bottom thereon, under the situation that constitutes a central gap, directly is contained in swingably on the pin 18.At the first parts 4a, the end that 5a radially outwards refers to is provided with the bowl-type clamping surface 6 that faces one another that is used for bottle 2.Each

manipulator

4,5 is along each two parts 4b, and 5b is designed to simple lever basically, and their central authorities' height part at the first parts 4a, in the breach of 5a, directly is contained on the pin 18 equally swingably.In the end that they radially refer to inwards, the second parts 4b, 5b are provided with the bearing surface that faces one another 7 that is used to strut part 8.Bearing surface 7 designs are being used on the plastic inserts 10 of highly abrasion-resistant, and inserts 10 is by means of the folding ground of dovetail shaped guide piece or be fixed on parts 4b replaceably, on the 5b.

Since the above supporting structure of introducing, the parts 4a of each

manipulator

4,5, b; 5a, b both can swing together, also can swing independently of one another.Pin 18 had both constituted the swinging mounting 13 of

whole manipulator

4,5, had constituted again to be used for parts 4a, b; The hinge 12 that 5a, b move relative to each other.This relative motion is subjected to design at the second parts 4b in a direction, the restriction of the backstop 23 on the 5b.

At parts 4a, 4b; 5a between the part of the substantially parallel extension that radially refers to inwards of 5b, on parts in the corresponding groove, packs into the elastoplast elastic component 9 of the pro forma microscler pad of silicone system for example.Elastic component 9 extends along the whole height of

manipulator

4,5, and attempts parts 4a, b; 5a, b presses off each other, until the restriction that is subjected to backstop 23.Elastic component 9 is directly arranged in inserts 10 back of band bearing surface 7, and can make parts 4a, b; 5a, flexibly relative motion between the b in this case, is located between bearing surface 7 and the clamping surface 6 by principle of work hinge 12, and is provided with one heart with respect to the swinging mounting 13 of manipulator 4,5.In addition, at two parts 4a that join double-

type manipulator

4,5, between the 5a, compressing the laminated spring 24 that rubs of V-arrangement with clamping surface 6, thin plate springs 24 is tried hard to manipulator 4 with being connected, 5 press off each other in the location of clamping surface 6, or give

manipulator

4,5 with predetermincd tension along opening direction.

Be parallel to each to pin 18 and at the parts 4b of the

manipulator

4,5 of two pairings, the central authorities between 5b, each rotatably is equipped with a control lever shaft 25 in ring 16,17.In the altitude range of ring between 16,17, what this control lever shaft 25 had that a cam-like has oval cross-section basically struts part 8, and it directly constitutes by the correspondingly local face that scabbles that extends in parallel on the control lever shaft 25.Be in its parallel side substantially along star conveyer 1 rotation axis position radially if strut part 8, then strut part 8 and determined the deployed position of

manipulator

4,5, because in this case, bearing surface 7 relies on recently mutually, and clamping surface 6 is each other from getting (Fig. 1 is right-hand) farthest.In this case, bearing surface 7 is pressed against on the side that struts part 8 under thin plate springs 24 effects, and bottle 2 can enter between the

open manipulator

4,5 in the clear.Elastic component 9 acts on parts 4a with thin plate springs 24, and the power on the 5a is passed to parts 4b, 5b.

Be in tangent with the rotation axis of star conveyer 1 substantially position, its parallel side if strut part 8, then strut part 8 and determined the make position of

manipulator

4,5, because in this case, bearing surface 7 each other from farthest, and clamping surface 6 relies on recently (Fig. 1 left) mutually.If there is not bottle 2, bearing surface 7 just under 24 effects of compacted thin plate springs, is pressed against on the narrow end face that struts part 8 so, at this moment, by the projection on one of two bearing surfaces 7 11, make to strut part 8 and slightly live in the dead point upper fixed, and thereby self-locking ground be in settling position.In this case, also transmitted by elastic component 9 by the power that thin plate springs 24 produces, elastic component 9 at this moment may be by compression.Distance between the clamping surface 6 is slightly less than the bottle diameter of minimum to be processed.

If in the make position that struts part 8 or

manipulator

4,5, bottle 2 is arranged between

manipulator

4,5, then have the parts 4b of

bearing surface

7,5b occupies identical position.But

parts

4a, 5a further separates in the location of clamping surface 6 each other, can accomplish this point by hinge 12.Elastic component 9 is compressed strongly, so elastic component 9 generations are used for fixing bottle 2 needed gripping powers reliably.Design parameters is for example selected like this, that is,

manipulator

4,5 can be caught the bottle 2 of from 60 to 70 centimetres of diameter ranges firmly, and meanwhile the amount of compression of elastic component 9 is no more than 1/3rd.The result who does like this is that the service life of elastic component 9 almost without limits.However, can be transmitted smoothly, need not repacking or change star conveyer 1 than the bottle 2 of major diameter scope.Because the gripping power that the compression of elastic component 9 produces produces additional stabilization to strutting part 8, therefore, strutting part 8 all is stable in make position still in deployed position, without any need for other fixed mechanism.

The lower end of every control lever shaft 25 under encircle 17 and slightly stretch out.On this overhanging end, be fixed with horn shape bar 26.It and locating

dowel pin

27,28 co-operation that are contained in star conveyer 1 below regularly.First locating dowel pin 27 is arranged in the inboard of control lever shaft 25 circular orbits.It spends part 8 revolutions about 90 that strut of passing by with star conveyer 1 along the direction of arrow, makes it to be turned back to make position from deployed position.Second locating dowel pin 28 is arranged in the outside of control lever shaft 25 circular orbits.It with one from the side process strut about 90 degree of part 8 revolution, be turned back to deployed position from make position.By other rigidity or adjustable for height locating dowel pin are set, can open reliably or closed

manipulator

4,5 in any one position of star conveyer 1 circular orbit.Therefore bottle 2 can be under the situation of the guiding bow that not have to add etc., target is transferred on the turntable that does not have expression the figure from transport plane 14 exactly, or transmit or be sorted into a plurality of different output machines, or be sent to from turntable on the star conveyer of a same-type with adjustable for height manipulator from turntable.

Can only be equipped with the manipulator of a door assembly with hinge and glass in right hand and left 12 and elastic component 9, another manipulator does not have hinge yet, that is be designed to rigidity and/or rotation is contained on the pedestal regularly and/or by driving device with opposite turning to and the coupling of elastomeric manipulator.In addition, it is also conceivable that to each manipulator and set a suitable part that struts.

Difference by star conveyer 1 shown in the star conveyer 1a shown in Fig. 3 and 4 and Fig. 1 and 2 is, the double lever type parts 4a of each

manipulator

4,5,5a, the section E perpendicular to the extension of

manipulator

4,5 oscillating axles along a level in central authorities highly distinguish separates continuously.Therefore each

manipulator

4,5 has two double

lever type parts

4a, 5a, and they can be swung toward each other.Single lever type parts 4b, 5b are different with it, are indiscrete.

Join double-type parts 4a for these two, 5a is by elastic component 9a, and the single parts 4b under being bearing in is on the 5b.As shown in Figure 4, each elastic component 9a has 4 elastic cylindrical pads, and they are connected to each other together by a thin elasticity contact pin.Per two cushions and upper-

part

4a, 5a co-operation, and two other cushion and

lower member

4a, 5a cooperating.Therefore, when acting on parts 4b, strut part 8 when being in its make position on the 5b, two parts 4a of each

manipulator

4,5,5a is adapted to the profile of the bottle of catching 2 respectively.In this case, the cushion of elastic component 9a may be subjected to diverse compression, as shown in Figure 4.Therefore, also can catch reliably and fixedly have so-called special-shaped bottle or a fancy bottle that is different from cylindrical surface.
