Abstract

A conveying method of the invention comprises the following steps: flow carrying a running container (1) in a container flow manner within a carrying section (U.1), a suspended conveying process of a conveying section (FS) which is set flexibly in a workshop and a detaching process in a delivering section (U.2). As for carrying the container, independent clampings (5), which are equiped equally spaced and adjoining with each other, are transported to the carrying section (U.1) from upper along a winding track (7') and are guided into the container flow between each container (1), while the winding track tangentially goes into a transported container track (8) on end of the carrying section. The clampings has larger speed (v') than the speed (v) of the container in a starting position for guiding and can reduce speed to the container speed during guiding the container flow. Due to coordination of conveying of the container and conveying of the clampings with each other, the container will reach the speed (v) of the container only when each clamping (5) encloses the container running ahead, that is, the clamping is transported to at least a possible holding position relative to the container. Finally, in the delivering section (U.2), the clampings (5) can rotate about a vertical axis in 180 DEG., thus the clampings, in a manner similar to carrying in the winding track, make the container separate to an output position. The winding track of the clampings (5) in the carrying section and/or the delivering section can be achieved by independently swinging of the clampings (5).

Description

The device of the method for suspended conveying of containers and enforcement the method

The invention belongs to the conveying technology field, relate to a kind of by first independently claim the described carrying method of preorder and realize the device of the method.The method that meets invention is carried with the suspension that the device of implementing the method is used for container, this container has definite bottom that container can free-standing that makes, and with the container bottom opposite opening portion portions, particularly constitute by neck and head, simultaneously, the sectional area of neck is little than the sectional area of head.This kind container for example can be a bottle, and it is made by glass or plastics usually, is used for holding beverage and other liquid for retail and wholesale.

By bottle defined above and similar container, be full of and closed state at it, be transferred by travel line with erectility mostly, travel line is made up of a series of delivery elements usually.Delivery element for example moves along conveyor zones by chain, and delivery element is fixed on the chain.This free-standing state at the bottle that is transferred on the travel line just makes in this conveyor zones significant rising to be arranged, therefore conveyor zones almost is arranged on the operation height usually, and essentially horizontally extend through between production and oil well cracking acid pumping truck, therefore arrangement and the personnel's traffic to station all produces very big obstruction.

Another shortcoming of above-mentioned travel line is, though bottle keeps the single-row of rule by combination of side guides, in these row, the spacing on throughput direction is difficult to keep accurately.Particularly when bottle is put on this kind travel line, when a travel line was transferred to another travel line, delivery speed also may change simultaneously, may cause the obstruction of bottle and slippage each other so.

Not only when combination of side guides, and when above-mentioned stopping state, bottle contacts to each other and rubs.This does not wish to take place under many circumstances, and is particularly for the bottle that has adhesive label, in the time of especially on tag just is pasted, all the more so.

In order to overcome the shortcoming of the above-mentioned carrying method of transport box on load-transfer device or delivery track, carrying method is also in continuous development, and in these methods, each transports by a clamper clamping and in suspension status individually at certain position of container at least.Clamper is fixed on the conveyer chain with uniform spacing.For by the clamper bearing container, make the continuous and absolute synchronization ground conveying of container and clamper.In the process of synchronous transport, each clamper is made a lateral excursion with respect to throughput direction, and drops to the container of (for example describing) on the container of wanting clamping or (for example describing) from the side near wanting clamping from above in US-3944058 in US-3590982.At the terminal point of skew stroke, clamper can clamp container and locking on this position.

For container is transferred to next feedway from a feedway, these feedways for example can be the devices of rectilinear load-transfer device and/or similar rotation, known have transfer-slewing arrangement, and it is equipped with the clamper (for example describing) that rotates in EP-0005402 or DE-19512515 in a substantially horizontal circumference.This clamper moves on circumference, and the feedway of this circumference and bearing container and the feedway of out-put container have a common tangent line accepting the position and deliver on the position.Utilize this kind transfer-slewing arrangement to accept and disengagement does not require the skew of aforesaid clamper.

Task of the present invention is, point out a kind of method, utilize the method, can accept by anchor clamps independently and have a definite bottom and one and the bottom container of opening opposing position (opening opens wide or sealing) basically, anchor clamps make container keep suspension status thus, and carried continuously on the conveyor zones that can in the widest scope, very at random arrange on the space, and can throw off once again at the end of conveyor zones.Come bearing container to flow by anchor clamps, promptly container transport can be carried out continuously and do not produced interruption.Container is thrown off from anchor clamps should be able to easily satisfy various demand.For entire method, container is remained on and the corresponding hanging position of container stand up position, and irrelevant with the variation of conveyor zones.

Task of the present invention also is, makes the device of realizing the method.This device should simply and take up an area of few, should be than known devices small investment, and operating cost is low again, mentioning during as beginning.The device that meets invention in addition should adapt to the shape and the size of the required container that transports easily, for example is fit to the bottle of different sizes.

These tasks are accomplished by the method and apparatus of definition in the claims.

In order to accept according to method of the present invention, make transport box with marshalling on container-conveyor zones, the form of continuous container flow is carried to the section of accepting, in this way, container is with given delivery speed, and with given, the spacing of rule enters in the section of accepting.Container keeps a stand up position simultaneously and acts on the carrying capacity of container bottom.

Further from top, along the track of a bending, make and equidistantly follow mutually each other, independently anchor clamps transport to the section of accepting, and make each anchor clamps between the container all import container flow, tangentially import conveyor zones in the end rails of the section of accepting.Anchor clamps have the running velocity different with container speed in the incipient stage that imports, and during importing container flow, anchor clamps slow down or accelerate to the container running velocity, that is, container and anchor clamps are transferred by the section of accepting with nonsynchronous speed.At this moment, the conveying of container transport and anchor clamps is coordinated with each other by this way, makes each anchor clamps, when walking around leading or the container that lags behind, it just reaches the speed of container, in other words, with respect to this container, having brought anchor clamps into one is in the possible clip position at least.(in the end of the section of accepting)

Also may make container in marshalling before the section of accepting is carried and give given delivery speed, meanwhile, the container spacing keeps equating (regularization).

Also may in the end of the section of accepting or afterwards, anchor clamps move relative to each other, to guarantee to clamp container.

In order to realize carrying, hang the container of clamping by each anchor clamps, begin from the section of accepting, and be transferred by the conveyor zones of in the space, extending arbitrarily, this moment, the position of anchor clamps can change with respect to the position of conveyor zones, thus make the position of anchor clamps remain on the corresponding container position of stand up position on.

At the end of conveyor zones, the container of the section of delivering separates with anchor clamps, and container and anchor clamps all are output on independent output section simultaneously.For container is separated with anchor clamps, according to the structure of anchor clamps and container different scheme types can be arranged, this also will elaborate hereinafter.

A lot of parallel container-conveyor zones also can be set, the container that the configuration of anchor clamps simultaneously should be able to a lot of parallel conveyings of clamping.The more anchor clamps of container are delivered into and accept also is conceivable in the section, so only makes every n anchor clamps run into a container.Also may be equipped with more, the section of accepting and the section of delivering of joining each other for example along container-conveyor zones, simultaneously in each section of accepting or the section of delivering, with the order (for example per the 3rd container) of rule or control according to demand, make container accept or decontrol by anchor clamps.

The device that meets invention has following component part basically:

-a large amount of anchor clamps and the suitable feedways that can swing with respect to conveyor zones, utilize this feedway, anchor clamps can be equidistantly and with the speed fast or slow with respect to the container kinematic velocity, on the track of bending by the top section of accepting that enters, in the section of accepting, anchor clamps can slow down or accelerate to the speed of container; And can be transferred through conveyor zones with by the section of delivering; For example one has hinged and keeps the conveyer chain of the anchor clamps of spacing with it, and this moment, these anchor clamps had on the track of bending than chain kinematic velocity faster;

-one acts on the container transporting device that is transferred container bottom, utilizes it, makes container on a upright basically position, carries on container-conveyor zones to the section of accepting; Belt conveyor for example;

-also may be useful in the control setup of single anchor clamps relative motion, utilize it can make anchor clamps bring a definite clip position and/or special accepting the position or deliver position (ejected position) into; For example static slideway, it is arranged in the section of accepting and/or the section of delivering at least.

-also may be useful in (side and/or in height) to adjust the setting device of container and be used to adjust given container spacing and given delivery speed, so that container transfers to the regularization device of the section of accepting; For example act on the regularization screw rod of vessel head or act on the braking of container bottom or quicken projection.

-also have another to make container output to the conveyer of container-output section from the section of delivering; Another belt conveyor for example.

The special advantage of the device of method according to the invention and implementation method is their simplicity (not skew of anchor clamps when accepting and throw off) and saves space (anchor clamps are from top importing container flow).Because avoided the skew of anchor clamps, the disadvantageous stressed relation that acts on the conveyer (for example conveyer chain) has also just been avoided.

According to following figure, the device to method according to the invention and realization the method is explained in more detail by different representative type forms of implementation.Diagramatic content is:

Fig. 1 and Fig. 2 are example to carry bottle, express two representational schemes that meet the inventive method;

Fig. 3 and Fig. 4 represent the simple representational form of implementation of of anchor clamps (not connecting with conveyer), and Fig. 3 is a upward view, and Fig. 4 is a cutaway view;

Fig. 5 and Fig. 6 represent another representational form of implementation (not connecting with conveyer) of anchor clamps, and Fig. 5 is for to accept/to deliver the upward view of position, and Fig. 6 is the upward view at clamping/perch;

Fig. 7 and Fig. 8 are illustrated in a representational form of implementation of the articulated lifting arm between anchor clamps and the conveyer, (Fig. 7) are the lateral plan perpendicular to throughput direction, and Fig. 8 is the cutaway view (Fig. 8) perpendicular to throughput direction;

Fig. 9 represents carrying and accepting a kind of representational form of implementation that realizes the equipment according to the invention of the method in the section by closing Fig. 1; (regularization equipment, container-feedway and anchor clamps-feedway)

Figure 10 represents to be used to carry by Fig. 9 the controllability of the device of differing heights container;

Figure 11 is illustrated in and carries and interior another form of implementation representational, device according to the invention of the section of accepting.

U.1 Fig. 1 has represented the section of accepting to meet first kind of pattern of inventive method, and conveyor zones very short one section and the section of delivering are U.2.Throughput direction generally illustrates with arrow F.The container 1 that is transferred is in graphic situation, the bottle that below opening seals in other words, has a flange 2, the flange 2 of bottle has maximum external diameter at the opening place, so just the retaining part below flange clamps bottle simply, is used for hanging carrying.

To the section of accepting U.1 container for example is transferred by load-transfer device 3 in succession with speed v and spacing d.

Anchor clamps 5 utilize connection 6 and feedway effect to be linked together, and are connected in upward motion of track 7 ' by this.Feedway is in the drawings by long and short dash line 7 expressions.May relate to simultaneously a conveyer chain that in corresponding guide piece, moves, anchor clamps 5 utilize connector 6, mode is fixed on this chain with a determining deviation as shown, so that anchor clamps are on the track scope of a bending, pass through with bigger orbit radius, so the speed of anchor clamps is faster than the speed of feedway.

Feedway is driven with identical speed v with belt conveyor 3, and U.1 anchor clamps 5 enter the section of accepting along track in the track scope of bending, its speed v ' specific rate v is fast.In the end of the section of accepting, the track 7 ' of anchor clamps 5 is with tangential remittance container-conveyor zones, and container-conveyor zones is essentially straight line and is catching by anchor clamps on the height of container, and container-conveyor zones is equally with long and short dash line 8 expressions.From importing some M, the speed of anchor clamps equals v.Between container-conveying and anchor clamps-conveying is so to guarantee synchronously, promptly in the end of the section of accepting, the joint M of anchor clamps-track 7 ' and container track 8 just, make each anchor clamps catch up with running container and clamp it at neck, as the anchor clamps that Fig. 1 shows, level is by joint M.Narrower than the clamping of flange by anchor clamps 5 in the clamping of neck, therefore when container leaves feedway, then continue hanging and transport by anchor clamps.

For can cross gradient on the conveyor zones FS and transport box still can be kept upright state, connector 6 has one hinged 10.Be the state of being kept upright, it is free-moving making articulation piece, then may be latched in a definite position for other mode of movement.

In the section of delivering U.2, for example can hand on the belt conveyor 11, container 1 is so that through transmission and container is transported, and anchor clamps 5 are upwards removed once more.Belt conveyor 11 has for example same with the feedway of anchor clamps 5 speed v simultaneously.Can on the track of bending, upwards throw off once more in order to make anchor clamps, anchor clamps are at the section of delivering start-up portion or in the section of accepting U.1 and the Anywhere in this way rotation of the section of delivering between the U.2 axle of the container that is held (for example around) U.2, thereby make anchor clamps clamp container from the front after rotation.Anchor clamps 5 are then being similar to the mode accelerated movement of the section of accepting, and therefore separate with container 1 and upwards leave.

When output unit 11 was bigger than the speed of the feedway of anchor clamps, the rotation of anchor clamps was just unnecessary.Before anchor clamps made progress, container was with regard to the clamping of release clamp.

Do not shift to an earlier date the anchor clamps of rotary course, described at Fig. 1, should be with the speed identical with anchor clamps-feedway with container-output unit, on the track of a bending, upwards remove from the section of delivering, a position (ejected position) must deviate to advance into, on this position, it can be slightly to surpass the speed of vessel head, and the speed that just surpasses flange 2 is upwards thrown off.This kind ejected position can be set up by the relative motion to each other of anchor clamps each several part.(seeing Fig. 5 and Fig. 6)

Fig. 2 has showed another scheme of the inventive method in the same expression mode of Fig. 1.In this two width of cloth figure, used same citation numeral for same object.

Anchor clamps 5 also are to be transported into the section of accepting U.1 on a warp rail 7 ' herein.Warp rail 7 ' forms by the overlapping of feedway track 7, track 7 for example extends in parallel with container-transportation section 8 basically, anchor clamps 5 have hunting motion around an oscillating axle perpendicular to throughput direction, shown in the figure, be round hinged 10 oscillating axle on the connector between anchor clamps 5 and the feedway 6.

The swing of anchor clamps by on throughput direction F is with from a pendulum position 5.1 to one and accommodated clip position 5.2, and in this swing process, anchor clamps have the high speed of container kinematic velocity v and catch up with the container that is transferred from behind.Obviously, the shape of anchor clamps 5, and the track 7 of feedway will adapt with the shape of container in case of necessity, so that the swing of anchor clamps 5 can not exerted an influence to container.

The stub procedure of describing in Fig. 2 has been represented the swing of anchor clamps along throughput direction, by this swing, anchor clamps are quickened with respect to container transport and conveyer and slows down.It is contemplated that in a similar manner and realize the swing opposite with throughput direction, like this, anchor clamps at first slow down, and then acceleration so that each container from the front by the anchor clamps clamping.

The section of delivering U.2 anchor clamps can put back again in the mode similar to the section of accepting, and container 1 with output unit, for example belt conveyor 11 identical speed v are failed away.

As already mentioned above, the scheme of describing in Fig. 1 and Fig. 2 of accepting also can combination in any, thereby the conveying on the swing of anchor clamps and the bending delivery track is superimposed.

The two demonstration of comparing of Fig. 1 and Fig. 2, when anchor clamps 5 corresponding structure patterns, the section of accepting and the section of delivering also can otherwise make up, and concerning the described scheme of Fig. 2, can use the scheme of the deliver section relevant with Fig. 1 equally.The scheme that will implement at first depends on the shape of the container that will carry, depends on the pattern of the conveyor zones that container transport will be passed through, and meets from other aspects and send device and container-output unit requirement before for container.

Anchor clamps keep equidistant and adopt hinged securement conveyer chain thereon, also can substitute with this anchor clamps, this moment, anchor clamps were arranged on the delivery unit that runs on independently of one another in the guide piece, and form one by flex link to each other " chain link " link, its spacing can change like this.When use this kind have between the chain link flexible connect and changeable anchor clamps of spacing between anchor clamps-during chain link, the container that is transferred for example can access buffering on conveyor zones.

For this kind form of implementation of anchor clamps-feedway and anchor clamps, before the section of accepting, be provided with the regularization device, it invests anchor clamps and gives determining deviation d and given speed v.Be used to make to each other the flexible chain link that connects to keep the device of regularization, (or US-4887809 describes in F245) for example, therefore no longer relates to its details herein in publication EP-309702.

Fig. 3 to Fig. 6 has represented two anchor clamps forms of implementation of giving an example, and it is suitable for according to scheme illustrated in figures 1 and 2.

Fig. 3 and Fig. 4 have represented a kind of very simple anchor clamps scheme with upward view (Fig. 3) and cutaway view (Fig. 4 analyses and observe figure line according to IV-IV among Fig. 3).Anchor clamps are a simple clamping fork 20, and it is transported with the arm that is parallel to throughput direction (arrow F or Rotate 180 °).Two yokes have spacing to each other, and the external diameter of this gap ratio neck is big, and the container that is transferred should be held on neck, but this spacing is less than its external diameter more than the neck (for example flange diameter).Neck and the flange of in Fig. 3, representing containers with long and short

dash line circle

22 and 23.

At the upside of clamping fork 20, the inner edge of yoke is made the conical surface 21 of part annular, and its top and bigger diameter are bigger than the lip diameter (circle 23) of transport box.As providing in Fig. 4, this conical surface is used for stable and centering.When accepting, the flange 2 of container 1 is arranged on the clamping fork 20 (container 1 is in the long and short dash line position of Fig. 4), pitches 20 besieged and by corresponding anchor clamps guide piece and/or at the guide piece of the section of accepting end container is fallen into to stablize the conical surface 21 by clamping.Container for needn't very meticulous disposal when it leaves feedway, can make container fall into the stable conical surface simply.For disconnecting process, with before anchor clamps separate, then for example make container rise to top position (representing) again with long and short dash line by output unit at container.

Stablize the nethermost part of the conical surface and also can make resilient lips.

Fig. 5 and Fig. 6 have represented another embodiment of anchor clamps once more with upward view.With regard to clamper 40, its two

pawl pincers

41 and 42 can enter an open position (Fig. 5: accept and deliver the position) and an off position (Fig. 6: stable or transfer position) by relative motion.Clamper 40 also has a control stalk 50 except two pawl pincers are arranged.

Pawl pincers can be distinguished 43 and 44 rotations around the shaft, be fixed on the phase clamper do not expressed on the connector of feedway, and each pawl pincers all have size and the bottleneck and the matched inner edge 41 ' of flange and 42 ' that are held.In addition,

pawl pincers

41 and 42 respectively have engaging tooth 45, and these teeth are engaged with each other together, make

pawl pincers

41 and 42 at least to 42 and 43 partial rotation around the shaft, and keeping each other, effect connects.

Control stalk 50 has two grooves 51 and 52, has in the

pawl pincers

41 and 42 of the bearing pin 53 that links to each other with

control stalk

50 and 54 any, can be movable in groove.By groove 51 and 52, two extreme positions of control stalk 50 and two corresponding extreme positions of

pawl pincers

41 and 42 have been stipulated: an open position (Fig. 5), on this position, control stalk 50 is horizontal basically perpendicular to throughput direction F, also has a locked position of coupler (Fig. 6), on this position, control stalk 50 is leading along throughput direction F in a side at pawl pincers 41.

For making clamper enter make position (Fig. 6) by open position (Fig. 5), clamper must clamp 42 sides at pawl, leans against on the slideway (slip plane 60 in Fig. 5) to slip over, and slideway is then braked the control stalk of this side of clamper.By this kind mode, control stalk 50 is with respect to 41 and 42 rotations of pawl pincers, and bearing

53 and 54 move in groove 51 and 52, obtains pawl by engaging tooth 45 thus and clamps 43 and 44 synchronous rotation around the shaft.If clamper changes open position over to by its make position, it slips on slideway (among Fig. 6, slip plane 61), and this moment, slideway just clamped 41 side brake control rods 50 at pawl.

For on unlimited and make position, fixing clamper, be equipped with a blocking device.For example be a ball 63, on the side that its close pawl that flexibly is placed on control stalk 50 clamps, also in pawl pincers 42 is provided with two corresponding location concave point (not shown)s for this reason.

Anchor clamps shown in Fig. 3 to Fig. 6 have been represented form of implementation for example, and its structural shape is used for the clamping and the conveying of regulation container.For using other containers, particularly there is not the container of neck, anchor clamps should adapt to these situations in the corresponding way.In each case, all clamp and make container being held when accepting by the back or by front (not being the side) at the opening of container.

Fig. 7 and Fig. 8 represented one exemplary, the articulated lifting arm spare 6 between clamper 40 and feedway is perpendicular to the lateral plan (Fig. 7) of throughput direction F with perpendicular to (Fig. 8 analyses and observe figure line VIII-VIII gained by Fig. 7) in the analysing and observe of throughput direction.Clamper 40 is described as the example of anchor clamps attaching parts 6.With the same manner, clamping fork 20 or other suitable anchor clamps of meeting Fig. 3 and Fig. 4 can be fixed on the connector 6.Clamper 40 is expressed out on its make position, clamps the neck that is transferred container 1 that has flange 2.Represent with same label at the clamper part described in Fig. 5 and Fig. 6.

Connector 6 has a swing component 70 and a connecting element 72, and the two links each other by articulated lifting arm 71.

Swing component 70 is a both arms shape.The structure of arm 73 is for parallel with 42 with pawl pincers 41 basically, and by bearing pin 74 and connecting element 72 hinged linking.Another arm 75 is vertical with 42 with pawl pincers 41 basically, and supporting can be around the pawls pincers of rotating

shaft

43 and 44 rotations, and in this way, the pawl pincers can rotate in the plane parallel with arm 73 basically.

The arm 73 that is parallel to

pawl pincers

41 and 42 of swing component for example also has 4 control bearing pins (76,77), and for controlling the swing that swing component 70 pulls to connection seat 72 relatively, they can be pulled.If these bearing pins are led by corresponding slideway (control plane that for example has long and short dash line 78 expressions), the swing position shown in swing component 70 remains on so, this has stoped swing freely in other words.If lack this kind or corresponding slideway, the swing of swing component 70 then is freely and is on the swing position corresponding to the gravity on bottle that acts on clamping and the clamper, in this way, bottle 1 always vertical hanging and be orientated along throughput direction substantially.The location independent of connecting element 72.

Also be provided with corresponding slideway, be used to control and accept or the swing position of anchor clamps when throwing off, as shown in Figure 2.

Fig. 9 represented one representational, realize the form of implementation of the device of the inventive method, device delivery part that has feeder (3 ') particularly, a regularization device (81/82), a container-feedway (3) and an anchor clamps-feedway (5/7/88), the section of accepting (U.1) of device and install the beginning part of transportation section (FS), and enumerate at last all corresponding to process program by Fig. 1.

Container 1 promptly is full of sends into first delivery track 3 ' (feeder) with the osed top bottle by a given traffic capacity (feeder-speed v .1 and bottle spacing are d.1) and go up guide piece 81 by being arranged on the bottle neck that is transferred, bottle is slightly raise by delivery track 3 ', in this way, the part of bottle weight is born by guide piece 81 at least.

Omit the bottle that lifting is got up through guiding and by first delivery track 3 ', next pass through screw rod 82 by regularization and acceleration, screw rod 82 has spiral, and around the groove 84 that cylindric screw rod body 83 is arranged, bottle continues to be led from the side and in height by guide piece 81 therebetween.Helical pitch from the entrance side 85 of regularization screw rod 82 to outlet side 86 grooves 84 increases, and in this way, at entrance side 85, d.1 the spacing of the bottle that helical pitch equals to be transported and at outlet side 86, then equals the conveying-spacing d of bottle 1 and feedway.Regularization screw rod 82 is driven with certain revolution by actuating device 87, the beat that this revolution is sent into corresponding to bottle and the beat of conveying.

The opening of the bottle that is transferred is the scope of input rule screw rod 82 by guide piece 81 guiding, location and pass through it by regularization and acceleration groove 84 in.Because this moment, bottle omited lifting from delivery track 3 ', so track also makes bottle be stabilized in stand up position, but it can be accelerated with respect to this delivery track 3 ' by regularization screw rod 82.Reach at bottle before the outlet position 86 of regularization screw rod 82, it is transferred on second delivery track 3 (feedway).The speed of this second delivery track 3 is given delivery speed v, and its speed with the bottle that detaches from the groove 84 of regularization screw rod 82 is identical.

On this ensuing delivery track 3, bottle leaves the groove 84 of guide piece 81 and regularization screw rod 82 and enters the section of accepting U.1.U.1 anchor clamps 5 are admitted to the section of accepting also in the mode as having described among Fig. 1.The feedway of anchor clamps is a conveyer chain (by long and short dash line 7 signals), and it is on the track of 90 ° of bendings of guide piece 88 interior about one-tenth, from the top importing section of accepting U.1.

Second delivery track 3 (feedway) the actv. section of accepting U.1 after termination so that it can and be used as stabilizing device when anchor clamps and bottle engage in stub procedure.

As seen from Figure 9, anchor clamps 5 can be swung (anchor clamps of going up most and other compare in different swing position) with respect to conveyer chain, and particularly for the accepting of bottle, the guiding of anchor clamps (slideway 78) can not freely be rotated it.

Figure 10 has represented to be used to carry differing heights bottle 1.1 and 1.2, meets the controllability of the device of Fig. 9.This device is drawn to be regulated for less bottle, and the adjustment that is used for bigger bottle 1.2 is with the long and short dash line sign.Simple in order to adjust, the guide piece 88 of regularization device 81/82/87 and conveyer chain rigid attachment each other also can be adjusted its height.

Less bottle 1.1 equally is transferred with anchor clamps towards the section of accepting is U.1 interior with same spacing, and each anchor clamps is accepted a bottle.Bigger bottle 1.2 is carried with double spacing in anchor clamps, thereby only is bottles of per two anchor clamps clampings.By this way, how many loads of feedway is able to balance when carrying the container of different sizes, and when the conveyor zones of steeply inclined, can avoid colliding of larger container.

For making the described two kinds of mode of movements of Figure 10 possible, the regularization screw rod must have the groove (double-threaded screw) of two parallel runnings, perhaps when accepting mode conversion, changes the regularization screw rod equally.In Figure 10,, only represented to carry the regularization screw rod and the groove of big required necessity of bottle in order to show clearlyer.

Figure 11 has shown that in the zone of carrying by 5 pairs of transport boxs 1 of anchor clamps and accepting another of device of the present invention implemented pattern.This embodiment is consistent with the device that meets Fig. 9 basically.The difference of two kinds of enforcement patterns is the structure of regularization device 82 '.Mainly constitute and act on the opening part of bottle by a regularization screw rod by the regularization device of Fig. 9, the regularization device 82 ' of Figure 11 then is made of a plurality of equidistant conveying projections, projection is for example by a space first and second delivery track 3 ' and 3, arriving uprightly has on the transporting flat of bottle, and acts on the bottom of bottle.Regularization projection 30 for example is installed on the electrodeless conveyer chain with the given conveying spacing d corresponding to bottle, and chain is driven corresponding to given delivery speed v.Implement pattern for this kind, the speed v .1 of feeder 3 ' is faster than delivery speed, thereby regularization projection 30 moves before bottle and it is played brake action.
