Abstract

A plastic clip in two parts is used for closing sausage casings, bags or the like. The first part (1) holds the end of the casing gathered together into a plait in a U-shaped cavity formed by side faces and cross-bars. The second part (2) bridges the cavity (4) of the first part and is lockingly secured to the first part. The second part (2) is linked at one of its transverse ends to the first part (1) by means of a film hinge (3) and has a locking arm (16) at its other transverse end that may engage a locking projection (22) on the other cross-bar (6) of the first part for closing the clip. A traverse (8) spaced apart from the cross-bar (6) next to the hinge interconnects the side faces (5) and is gripped in the closed state by an arm on the second part, so that a high closing pressure is exercised at the same time as the required elasticity is maintained. A device for closing such a plastic clip has two cavities (37, 39) for receiving both clip parts (33, 34). One cavity (37) is fixed and the other (39) may swivel around an axis (40) aligned with the hinge axis (35) of the clip parts (33, 34). The second reception cavity (39) is swivelled into the closed position of the clip by a mechanical drive (38, 41, 42). In an improvement of the closing device, a positioning arrangement (50) feeds the clip to be closed from a supply channel (32) to the reception cavities (37, 39) of the closing mechanism by means of a cam-controlled driver (56).

Description

Plastic clip consists of two parts and device for its closing

The invention relates to a ursthüllen for closing, bags o. The like. certain plastic clip consists of two parts which comprise the gathered into a braid sheath end and are connected verrast- bar, wherein a first part with one of side walls and Quer¬ webs formed receiving space comprises the braid part and a second part of the transverse webs of the first part bridged, and wherein the second part is articulated with its one transversal end on the corresponding lateral end of the first part by a film hinge, with a projection engages beneath a portion of the first part in the closed state and in the region of its other transverse end has a locking member which with a complementary locking element on first part zu¬ sammenwirkt. The invention further relates to a device for closing of such clips or its multiple, are connected to form a chain. A well-known from the US-A-4,275,485 plastic clip of this type has not shared in the closed condition the form of a (largely hollow) cylinder and along an axially parallel plane. Aufnahme¬ against the space in the larger first part projects a rib in the second (lid) - Part, but achieve only disposed thereon 'spikes' the top side bounded by the end-face side walls for the passage Zopfmaterial. A to the film hinge toward directed projection on the rib of the second part pivots on closing the clip in a recess which is internally provided in the receiving space limiting the manner of a transverse web between the side cheeks cylindrical outer wall, and in this way leads to a schar¬ niernahen locking Of the parts. Opposite engages a trained on the second part latching hooks in a latch opening in the cylindrical outer wall which forms an opposite transverse web there.

By the in the closed position - over the process known from EP-A-356850 plastic clip additionally - taking place locking the two parts in the region of the film hinge above all, a higher clamping force may be applied to the braid of the sausage casing or the like... However, it is unsatisfactory that the locking is very rigid and for example no elastic yielding of the clips allows, if pressure peaks occur, for example due to heat treatment of the package contents on the clip and must be removed by venting. The same applies to the adaptation to different Zopfdicken.

The problem mentioned above meets the invention in that a parallel but spaced extending to hinge near the transverse web cross-member connects the side cheeks of the first part ver¬ and a benach¬ at a corresponding distance the film hinge barter arm on the second part in the closed state between the transverse web and the Traverse and reaches under the crossbar. Here gewähr¬ the arm makes in cooperation with the traverse both reliable guidance of the two clip parts during the closing process as well - by the positive locking in the closed position - a high clamping force transmission in the hinge area. Above all, the clip has ge connected due to the distance from the locking Aufnahme¬ space despite the high clamping force-transferability sufficient elasticity to different and / or changing Be¬ anspruchungen.

Particularly advantageous is the formation of the new plastic clips is such that the first part is arranged extending transversely to the Zopflängserstreckung side panels with the center having depressions aligned Ver¬, while the second, the receiving space in wesent¬ union overlapping part a projection in the form of a parallel to the side walls extending and projecting into the receiving space rib is integrally formed, so that in the locked closed condition of the clip the plait is wavy deflected and is under closing pressure.

Such a clip construction is known in principle from WO 93/10012. Here, one embodiment of two identical parts, the - rotated through 180 ° - can be latched to one another, another of two different parts, where instead of a bottom-closed receiving chamber, an open frame is provided. Both embodiments of this known plastic clips fulfill their task to adapt automatically different volumes of Hüllenzopfes and optionally vent an overpressure occurring for example in the production of sausages inside the envelope without subsequent leakage loss due to elastic yielding, but can - without the connection of the two parts - the processability in something to be desired fast-acting sealing machines.

A safe and above all non-interacting with the force exerted on the braid closing force locking is obtained if the side walls extended in accordance with another advantageous embodiment of the invention also on the latching side and are connected by a second traverse and the latching arm between the second beam and is guided to their adjacent other transverse web, wherein the locking projection at the other transverse web is advantageously part of a tongue, which starts at the free edge of the transverse web, extends back to outside of the trough and is biased away from the transverse web away resiliently.

Finally, it will facilitate the automatic processing of the new clip, in general, characterized in that integrally formed, separable webs connect the free end of the second part with the free end of the first part of a similar clip to loadable chains. These webs can be cut easily located during the closure, as is known from the processing of conventional metal clips ago.

The inventive device for closing plastic clips of the type described above has, in its most general form:

a) a stationary first holder for the one clip part; b) a pivotable about the hinge axis of the clip parts second support for the other clip part; and c) a pivotal movement of the second bracket from an open leading to a closed clip position drive.

Typically, the holders from receiving depressions which are adapted in their configuration to the outer shape of the two clip parts, so that the clamping force uniformly introduced into the clip and a locking of the two clip parts is achieved in a pigtail firmly um¬ closing position. While the first holder for the one clip part is fixed and this clip member such positio¬ ned that the plait - arranged accordingly by one and formed feed slot - can be inserted in this clip part is (once this has been done) of the other clip part by means of the movable second bracket pivoted to the hinged connection of the two clip parts and made the latching.

Advantageously, the second bracket leading driving a gear, which by means of a meshingly engaging driving member (rack, pinion o. The like.) By a certain angle from the open to the closed position of the clip is rotatable. operating as a source of An¬ can serve, for example, a pneumatic cylinder, which reciprocates the drive member back and.

Preferably, a perpendicular to the pivot axis (of the holder and thus the hinge axis of the clip parts) is provided in the brackets opening out feeding channel for a sequence of clips and a separating said to be closed clips of a clip chain during pivoting of the second holder favoring abutment. In this way, the removal of the clips being processed by the fed through the feed strand takes place automatically, so to speak during the closing process.

According to a further embodiment of the invention is a Positionier¬ device is provided which feeds each of the clip to be closed into the holders. In particular, it has a driver, which is engaged by in each feed cycle is a part of the channel-held ready in Zuführ¬ clips, moves it in the first Halte¬ tion and then moved back out of the clip out and on an arcuate path in the starting position. Over the feed portion of the carrier movement, which effectively extends tangentially from the mouth of the feed channel, so there is a positive connection between the driver and the one clip part, until the latter is positioned in its holder. Then shall the driver - perpendicular to Länαserstreckung this Clip¬ part - moved so that it makes the space free for the ein¬ feeding Beutelzopf and on his way back to the development Ausgangsstel¬ the clip can not be affected.

Preferably, the feed cycle of the cam is cam-controlled, advantageously in such a way that the driver sits on the piston of a pivotally mounted pressure fluid cylinder and also engaged by a guide pin mounted on the piston in a Mitnehmerbewegung be¬ the tuning setting.

The first part 1 and the second part 2 of the in Fig. Clip shown be¬ projecting from a sufficiently hard, but still elastic plastic material 1 are connected by a film hinge 3 hinged together. The first part 1 consists essentially of a U-shaped wall which is formed of parallel transverse webs 6 and a bottom 7 and serves as a receiving space 4 of the Hüllenzopfes. On both sides put on the transverse webs 6 side walls 5 and are connected near the hinge 3 by a cross member 8 and at the opposite end by a cross member 9 to each other; the cross members 8, 9 extending parallel to the transverse webs. 6

The second part 2 has an arcuate lid portion 11, which merges at its one end in the film hinge 3, which attaches the other hand on the cross member 8 of the first part. The width of the lid portion 11 is slightly smaller than the clear width between the side walls 5 of the first part 1 (Fig. 2).

Close to the hinge-side end of the lid portion 11, an arcuate arm 13 is formed at the second clip part 2 which bears in the closed state of the clip with its concave inner side 14 according to the curved surface 15 of the cross member. 8

At the opposite free end of the lid portion 11, a locking arm 16 is integrally formed on its inside with locking projections in the form of detent steps 17, 18 is provided and 19th In the closed state engages at least one of the latching steps 17 - 19 via corresponding latch stages 20, 21 on a tongue 22, which attaches 9 notify hard crosspiece 6 on the upper edge of the crossbar and extends in the passage 23 between this transverse web 6 and the cross member. 9 The (filmscharnier- like) link 24 between the tongue 22 and the crosspiece 6 of the receiving space 4 biases the tongue 22 elastically into the passage 23 into front and gives it the function of a ratchet which elastically during the closing of the locking arm 16 on the second part 2 for adjacent transverse web 6 can be pivoted until the suitable for the respective Zopfdicke latching steps 17 - 19 engage the latching arm 16 behind the detent steps 20, 21 on the tongue 22nd The traverse 9 supports the latch arm 16 to the other side from back.

In the second embodiment of FIGS. 3 et seq., The first part 1 a trough-shaped receiving space 4 with parallel verlaufen¬ the side walls 5 and transverse thereto, but among themselves also parallel cross-members 6 and a bottom 7. The Seiten¬ cheeks 5 are provided on both ends extended beyond the transverse webs 6 and also connected close to the film hinge 3 by a cross member 8 and at the other end against ent by a cross member 9 to each other; the cross members 8, 9 extending parallel to the transverse webs 6. In the region of the receiving space 4 are formed ausge¬ in the side panels 5 mutually aligned, not reaching to the bottom 7 recesses 10 into which (not shown) during the closing of the Hüllenzopf is inserted ,

On the second part 2 along the longitudinal center line of the Deckelab¬ section 11 and over a central part of its length a rib 12 is formed, which in the closed state of the clip in the center between the side walls 5 and parallel to these in the receiving space 4 er¬ stretches and in the wavy depressions 10 deflects inserted Hüllenzopf in the receiving chamber 4 into and fixed clamps. The arcuate arm 13 is effectively formed as an extension of the rib 12th

While Fig. 5, the engagement of the ratchet steps 18, 19 on latch arm 16 is behind the locking steps 20, 21 on the tongue 22, the latching steps are shown in FIG. 8 latches 17 and 18 with the locking steps 20, 21. Referring to FIG. 7, there is - in a very thick braid - the latching only between the locking steps 17 and 20.

In Figs 9 and 10 shown concatenation of similar plastic clips to a loadable -. For example, roll-up cash - band is formed by severable webs 25 which may be of integrally formed during the manufacturing process of the clips and the respective free transverse edge of a second part 2 ( combine close to the latch arm 16) with the free edge of the first part 1 in the region of the traverse. 9

In the housing 31 of the device shown in Fig. 11 is a Zuführ¬ is channel 32 is provided for plastic clips in chain or strand-like Anein¬ other ranking, as shown in FIGS. 9 and 10. . In the illustration in Figures 12 and 13, such a (partial) strand located in the feed channel 32; each clip consists of the part 33 and the other part 34, which are at 35 connected by a hinge Film¬ hinged together. Easily separable webs 36 connect adjacent plastic clips together.

. Further below to be¬ writing positioning - - In the illustration in Figure 12 which has the front plastic clip of the strand inserted into the lock mechanism, which trough a fixedly arranged in the housing bracket in the form of a Aufnahme¬ 37 for the one clip part 33 and a having on a gear 38 (see FIG. also FIG. 14) disposed second support also in the form of a receptacle cavity 39 for the other clip part 34. The articulated connection between the two clip parts 33, 34 is in the form of the film hinge 35 while in the rotational axis 40 of the gear 38th

A longitudinally displaceably mounted in the housing 31 rack 41 can be made of their in Fig. Inoperative position shown 12 are moved to the shown in FIG. 13 working position, with the aid of a indicated in Fig. 11 only by the dot-dash line 42 the pneumatic cylinder (there is also the rack 41 with only a schematic outline indicated).

Upon actuation of the pneumatic cylinder 42, the rack 41 rotates the gear 18 about the rotational axis 40 in the clockwise direction. 39 thereby receives the second receiving recess with the other clip portion 34 until it is connected to the one clip part 33, which remains firmly in its first ver¬ receiving trough 37 is locked; This state is shown in Fig. 13.

Previously -. While the parts still in their in Figure 12 darge set relative position were - in Figures 11 - bag 13 shown with a black circle braid 43 of a Verpackungs¬, a sausage casing or the like through the slot 44... been guided in the housing 31 and in the receptive opening in the clip portion 33rd Thus, the braid 43 and the subsequent in its longitudinal direction package portions during insertion of the braid do not collide into the plastic clip with the gear 38 and also its pivotal movement during closing are not in the way of a correspondingly shaped recess 45 is provided in the gear wheel 38 (Fig. 14 a and c). Fig. 14b illustrates that the actual gear 38 laterally offset relative to the feed channel 32 is disposed and projects only with a lateral projection 46 approximately in the form of a circular quadrant in the feed path of the plastic clip, it being understood that in this feed direction of the tab 46 with the second receiving well 39 for the clip member 34 for a clip in alignment part 33 with the receiving depression 37th

The positioning means for the plastic clip in the Aufnahme¬ troughs 37, 39 is a total of Fig. 11 can be seen. It comprises a pneumatic cylinder 50 which is mounted in a pivot bearing 51 on the housing 31 about a longitudinal axis perpendicular to its axis extending pivot. The piston 52 continues into a slide 53 whose formation is apparent in detail from Fig. 15. On the slider 53 (kolbennah) is a guide pin 54 projecting laterally heraus¬ fixed and engages (by means of a ball bearing on its role) in a slide 55 a, which is shown in detail in Fig. 16. At its opposite end the cylinder 50, the slide 53 carries a laterally projecting in the same direction as the guide pin driver 56, the discrimination, the actual Positio¬ the clip into the receiving troughs 37, 39 performs.

The configuration of the slider 53 is shown in Fig. 15. In the threaded hole 53a of the piston 52 is attached. In the blind hole 53b the guide pin 54 is to be inserted, while the blind bore 53c is used to accommodate the driver 56th

With the piston 52 of the pneumatic cylinder 50 in its retracted starting position, which is shown in Fig. 11, the guide pin engages 54 (the slider 53) in the slide 55 in its lower left corner (Fig. 11, 16). When the piston 52 driving ausge¬, so the spool 53 moves to the right (in Figs. 11, 16), and the guide pin 54 moves in the lower, substantially horizontal branch of the connecting link 55 in the lower right corner. During the subsequent retraction of the piston 52 in the cylinder 50 acting as a baffle partial depression 55a of the connecting link 55 provides (which for the horizontal branch of the connecting link 55 towards has a shoulder 55b for the episode) outward spring bias arranged in connection with a side of the guide pin 54 roll (not shown) ensure that the guide pin 54 can not return to the issue in the wesent¬ horizontal branch of the slide 55, but the upper, arc-shaped branch passes, wherein a kind of ramp 55c returns to the initial depth of the gate 55 (FIG. 16b ). The guide pin 54 of the slider 53 and has the piston 52 and the cylinder 50 to follow in that it pivots about its pivot 51st When the piston 52 has been completely withdrawn into its starting position (Fig. 11), then the cylinder 50 has assumed its essential borrowed in the horizontal position again; at the last, starting weitge¬ vertical piece of the connecting link 55, the return movement is facilitated by the in FIG. 11 right of the pivot bearing 51 acting greater weight.

The above-described movement of the guide pin 54 in the connecting link 55 during a working stroke of the piston 52 (and therefore the spool 53) must necessarily also the driver 56 join. In the initial position it engages with a - the one portion 33 of the clip adapted - mandrel 56 a positive fit in those clip members; this position of the follower 56 in Fig. 11 as "A" gekennzeich¬ net. Upon extension of the piston 52 and the corresponding movement of the guide pin 52 in the horizontal (substantially) branch of the connecting link 55, the carrier 56 moves correspondingly to the right in Fig. 11 and takes the clip part 33 and the hinged thereto other Clip¬ part 34. Because the recessed receiving trough must pass 39 in this way of a clip member 33, in the connecting link 55, a entspre¬ sponding recess 55d (Fig. 16a and c) is provided, due to which the cylinder 52 and to pivot slightly downward in accordance with the slider 53 and no risk of lost the positive connection between the driver 56 and a clip part 33 that goes. In the further course of the outward movement of the piston 52, the driver 56 finally presses the one clip part 33 in the stationary receiving trough 37 so that then the plastic clip has a total reaches its initial position for the closing operation; the driver is located in the position "B". During the subsequent return stroke of the piston 52, the carrier 56 is moved due to the forced by the connecting link 55 Schwen¬ effect of the cylinder 50 to the slider 53 through the passage 57 formed in the housing 31; (Only) of the participants is Mit¬ 56 shown therein in various intermediate positions for illustrative purposes. Finally, the follower 56 comes back to its in Fig. 11 dargestell¬ th initial position, while the latch mechanism performs its closing operation described above. Insofar as not engaging the next clip driver 56 forms the required abutment for the separating of the clip located in the closing operation, this object is achieved by the abutment 58 on the channel 57 surrounded by the heart.
