DD275650A1 - DEVICE FOR CLOSING CONTAINERS IN FUEL LINES - Google Patents

Abstract

The invention relates to an apparatus for closing containers with a push-in cover, with an unstacking unit (1-6), an inclined slide (15) arranged thereafter with a cover-allocation system (8-12) situated at its end, and a supporting roller (12) articulated on the inclined slide (15). The unstacking of the covers is carried out by means of rotatable catches (6) which can be operated by means of a linkage which is moved by the arriving containers. The stop (10) of the cover allocation, which engages laterally on the cover, is arranged, via a further linkage, to be releasable by the containers supplied. The supporting roller (12), which is vertically liftable above the containers transversely to the conveyor device and is arranged after the inclined slide (15), stabilises the sliding of the cover onto the container opening. <IMAGE>

Field of application of the invention The invention serves to close containers in FQIIinlen. Characteristic of the known state of the art In principle, among the two conceivable possibilities, lids are to be allocated to the containers to be closed, namely they are vertical

settle or top Schragen bring to the meeting point with moving containers, also known technical devices.

When placing lids vertically on containers, ζ. B. medium "allocation by screw ^ in which the container

under the lid stack anhllt and what only applies to round lid, the lid must at least two, usually three

Fixed points and released at the same time at the same time, so that he finally in free Faii on

Lower the container.

The disadvantage is that the so deposited lid on the containers only fluttering and therefore not in their final position

can be defined endlessly reproducible (see DE 2519183).

In any case, in order to rule out the misalignment of such lids on a container, the support for them will not be 'in advance'.

canceled, but operated until the top of the outgoing groove of the depositing spindle, the lid is pressed onto the container (see DE 2560141).

The disadvantage is that the lower support, lateral guidance and lying on the lid upper groove edge pressure not

can be solved at the same time and with little effort, because production-bound games can not be ruled out, so the precision required for functionality is not achieved.

The Nachtelle hinder in particular the safe achievement of the required for the closure lid-BohSIter content. This is also the most essential requirement for the subsequent closing process by means of a stamp im Stand or by driving under a pressing Verschließrollo. Therefore, it is essential to find another way To place the lid on their associated container, namely to align the ceiling supply so that the same safe

be guided on the containers and with the same in a reproducible proper engagement to him after this first station of the device on a second downstream, close to the described first finally "locked".

The lid is placed in contrast to the top of a moving on a conveyor container, what he out

fed to a magazine via a slant and the same exits after the release of the same, over the front

Slipped container edge and from the moving container out · or is used to itself. So that the lid does not "slippage", is located above it, acting in the direction of its line of movement,

directly at the point at which exits under the influence of gravity and after the slide trigger the lid from the slope and engages the container edge, either already the Deckeleindrückvorrichtung "talle" or an additional Deckelflxierung from above (see DE 2465900 and DD 90314).

The disadvantage here is that by means of this tight downstream of the pressure roller to the slide exit as a cover guide only

works for plastic lid.

The lid wfire while ready! Detecting the same through the container even before complete release from the chute with

loaded considerable pressure, which can lead to a lid deformation, which remains without consequences only in plastic lids.

Furthermore, it is disadvantageous that such a lid Behätterzusammenführung succeed only in slip-on lids. To the same

include plastic cover for pressing and screw cap. These are made against friction through the can from the

Oblique slide, where they are in readiness, in principle pulled out. Furthermore, the release of the lid according to DD 90314 is disadvantageous because here the mechanism of each lid on the Oblique chute locks twice and therefore no longer supplied to the container too dense conveyor sequence in time

can be. In principle, the lid sequence depends on this, albeit slightly behind the container sequence.

On the other hand, according to DE 24 55900 the lid when meeting with the container is not triggered in principle

but only pulled out of their spring-loaded locking by virtue of the mass of Andruckriemens stationary standing on the conveyor belt container. This means that each container takes its lid, so lid sequence and

In principle, cover bookings. Another disadvantage is also generally that in the manner described last impression lid containers for several reasons not

can be assigned.

Object of the invention

The invention has the goal to automatically close containers at high speed and reliable with Eindrückdeckeln.

Essence of the invention

The invention has for its object, containers Eindrückdeckel slip from a slope, which is preceded by a stowing Özu entstapelndes deck magazine, in the form that they coincide without free fall, without deforming influence on a Envelope in the can opening, with the same functionally reliable and form, by a further device, closable lid-container unit.

This object is achieved in that starting from a present in the Schrickrut Eindrückdeckel which is locked in a form-fitting manner at the delivery point, the device successively following steps are performed:

- Disconnecting the bottom lid of the lid stack, which falls into the chute and unlocks the already existing lid;

- Release the locking of the ready lying first lid by the delivered container;

- Sliding this lid against the inner front edge of the insertion opening of the container;

- Supporting this cover by a support roller, which passes over its rocker lid of the envelope, which follows the lid when sliding onto the can, correspondingly from above by low pressure and wide guide;

- Completely sliding de lid ι from the oblique slide by virtue of its weight and the weight of the upcoming second cover on the Endki / ite of the inclined chute and slipping of the second lid against the re-closed lock, in which position the subsequent lid the slipped, folded lid In overlapping the moment;

- Further transport of the lid-container unit for closing by pressing the Deckenis and simultaneous repetition of the process, starting with the new unstacking of a lid, the container sequence can be arbitrary, so also close to tight.

These functions of lid destacking and allocation, handover and transfer, and functional lid-bin unit formation, including its fluid sequence, are effected by the following subdevices, which will be described individually below, one by one:

1. destacking device

For destacking two rotatable pawls are used, on the lower segments of the lid stack is seated in rest position and perform a small rotational movement detected by a supplied by zoomed container rocker while pushing off the bottom lid of these segments and by means of the penultimate cover cross-olber segments Support the lid stack. When released drag lever takes place by means of recovery by spring force the implementation of the stack of lids from the upper to the lower segment. Further details can be found in the embodiment with the corresponding representation.

2. Lid lock in the slide chute

A mounted on a vertical shaft with return spring side lock, which performs a horizontal rotational movement in their solution, the cover web narrows in locking position so that the lid leading edge is locked a few millimeters above the can opening. The drag lever on this shaft, when it is detected by the passing through filled container, the unlocking of the bottom lid by horizontally turning away in the transport direction of the can. Further details are also reproduced in the exemplary embodiment.

3. Swinging support roller

The support roller is fixed to a rocker, which is oriented in the direction of travel and can be lifted in the vertical direction, strengthened. It is locked in the lower position so that it does not affect the sliding of the lid when it is unlocked in the container opening, but only counteracts a jumping out of the same from the opening. The envelope of the lid, which is produced during the further transport of the container, follows the supporting roller blind and acts thereby stabilizing on the cover layer. details

Details are also to be taken from the Ausfährungsbeisplel. The mass of the support roller, its storage and arrangement ensure that act on the lid only small KrSfte and deformation is excluded. This lid-container unit is then fed to a push-in device.

exemplary On the basis of the sketches, the function and mode of operation of the device will be explained n & her. 1 shows the overall view

the device, Fig. 2 a and 2 b the Destacklerklinken.

On the base plate 1, the guides for cover stack and the journals of the pawls 6 are attached. A filled container transported on the conveyor belt detects the drag lever 2 and rotates the shaft with return spring 3

about 16 *, thereby lead the rocker 4, which are connected via coupling 6 with the pawls 6, same direction rotational movements and the lower segments 13 of the pawls 6 unlock the bottom lid of Decketstapels. At the same time push the upper segments 14 of the pawls β under the penultimate cover and lock.

When the container leaves the operating range of the drag lever 2, the return spring of the shaft 3 rotates due to the Bias of the return spring back to the starting position, thereby giving the upper segments 14 of the pawls β Cover stack free and the lower segment 13 of the pawl 6 locks. The released bottom lid falls into the chute 15, which has a tilt angle to the container transport path of 30-35 "

has and closes for standing in the lid. The container has already destacked a lid for this subsequent catfish. By the further transport of the container this detects the drag lever 8 of the shaft

Return spring 9, thereby the hinged on the shaft 9 lock 10 is opened. Since the opening track of the barrier 10 is parallel to the container transport path and the chute 15 to both an angle of

30-35 'form, the lid is released after a very small angle of rotation of the lock, so that the lid immediately supported by the mass of the digested lid additionally supported in the small distance under the lid

Container, safely guided by the chute 15, slips against the front edge of the container opening. Upon further transport of the container, the inclination of the lid to Behälterß.Vnung of about 30-35 'decreases continuously

to approximately 0 ° and works when reaching the end edge of the chute 15, the slide center corresponds to the container opening.

At this time, the drag lever 8 is effected from the sphere of action of the container and the shaft with return spring 9

a reset of the lock 10 in the locked position for the subsequent cover.

The unlocked lid lays down after folding down its predecessor a way of about 6 mm before he locks Thus, the lid is already in handover takeover condition before the next cans take the lid takeover position

to reach. This catfish is secured so as to cover a Dicht_-an-dense sequence of containers for the following container

Always a lid is in readiness before a container reaches the takeover position.

During the sliding of the lid against the inner front edge of the Eindrücköffnung of the container, the lid is through

the support roller 11, whose axis is guided parallel to the container opening by the rocker 12, normally not touched. you

Is adjusted so that only possible jumping out of the lid is prevented from the can opening. Upon further transport of the container, the support roller 11 follows the envelope of the sliding lid and prevents tipping

of the lid.
