Technical Field

The present invention relates to a device and a method for conveying cut and filled flexible tube segments in a machine for producing pouches filled with infusible material.

Background

A generic device is known from EP 2681119B 1. The device has a transfer wheel comprising a plurality of bag receptacles distributed over its circumference.

In this previously known device, cut and filled hose segments are inserted radially into a transfer wheel, so that a pouch is formed from the hose segments. In doing so, the flexible tube section is formed such that a pocket cavity is formed, which pocket cavity extends radially with respect to the transfer wheel, wherein the bottom of the pocket rests radially inside and the head of the pocket rests radially outside. In the description of the invention this station is also referred to as an insertion station. Thus, it is within the scope of the present invention that the cut and filled hose segments may also be configured as single or dual chamber pouches. In any case, after the insertion station, the initially flat pre-cut is formed such that the shape of the chamber and thus the pouch is substantially predetermined. The head is exposed in the area of the outer circumference of the transfer wheel. In the subsequent processing step, and when the transfer wheel rotates, the labels are fed to and connected to the head of the pouch according to the state of the art. The pouch is then wrapped in a length of packaging. The package is placed substantially in a U-shape around the pouch. The opposite edges of the package are then welded together to completely seal the pouch within the package. The package is formed of a film through which the pouch is hermetically sealed in the package by the fragrance.

When opening the resulting packaging unit consisting of the packaging and the pouch, the packaging is usually opened in the region of and along the transverse welded seam. The end consumer then wants to grip the pouch via the label and pull it out of the opened package. This requires that the transverse welded seam delimit the packaging at the location where the pouch with its label is placed.

In the state of the art mentioned above, the pouches are pushed radially out of the transfer wheel together with the labels, and a length of film of the wrapping is placed between the transfer wheel and the pushed-out pouch and then moved back into the transfer wheel together with the wrapping (which is placed around the pouch in a U-shape). In the next station, the sealing of the packages takes place. During this process, the packages are held together with the pouches in a transfer wheel in a predetermined position. The U-shaped sealing jaws grip the package from the outside and in one step create a longitudinal welded seam and said transverse welded seam, so that the pouch is received hermetically in the package.

It is complicated to push the pouch out to pack it in a package. Considerable mechanical components are required to safely and reliably control the process. Furthermore, sealing the packs on the transfer wheel results in a relatively long dwell time of the pouches on the transfer wheel, since the welded seams produced during sealing must first be cooled and held by the transfer wheel before the wrapping units can be radially discharged from the transfer wheel.

Disclosure of Invention

The problem on which the present invention is based is to provide an apparatus and a method of the type mentioned in the introduction which solves all or part of the problems mentioned above.

In order to solve this problem, the invention provides a device having the features according to claim 1. In this device, the support is pivotally mounted.

This configuration provides the possibility of producing the pockets in a generally known manner so that the bottom is leading in the transfer wheel and/or inserting them into the transfer wheel. Thus, it is within the scope of the present invention that the pouch be preferably produced as a dual-chamber pouch. In this case, the front and rear arms assigned to the support element grip the cut and filled tube section in the region of their respective free ends, while the middle region of the tube section is lowered radially into the transfer wheel. For this purpose, according to the invention, the transfer wheel preferably has a front arm and a rear arm of each support as is known, for example, from DE 3806386C 1, which interact with and grip the respective end regions, for example against the cover, and form the head of the pouch when the front and rear arms are moved together, so that the initially free ends are applied against one another (if there is also a need to fold them) in order to close the pouch at the end of the head. In this case, the transport wheel can be retracted onto known devices and measures can be taken to form a bag, in particular a two-chamber bag, closed at the top from the tube section which has been cut and filled.

The device according to the invention may therefore also have a profiled section which is provided between the respective arms of each support and which forms the bottom of the pocket in the region of the insertion station and which can be lowered so that it is radially inwards towards the axis of rotation of the transfer wheel.

The contoured portion is typically recessed into the support and may be part of the support. The support according to the invention is configured such that it can receive and retain within itself the chamber of the pouch. The support may hold and position the labels in a subsequent station, in which the labels are fed in a known general manner towards the head of the pouch to be formed.

The support of the device according to the invention is a part that receives the finished formed pouch (which has usually been closed at the top) and holds it while the pouch thus formed moves in the circumferential direction and thus in the conveying direction of the conveying wheel. An arm for forming a pouch from a flat cut flexible tube section filled with infusible material is arranged to the support. However, these arms are not part of the support. Instead, the formed pouch is fed to the support by means of an arm.

The pivotable support allows the pouch to pivot before it is removed from the transfer wheel so that the pouch is positioned with its bottom radially outward. In this way, the pouches can be removed from the transfer wheel and transferred to the sealing station, for example, decoupled from the rotational movement of the transfer wheel according to their time setting, so that the processing steps performed on the transfer wheel to complete the pouches are not prolonged by the holding and cooling times associated with the sealed packaging and production of the wrapping units. For example, the sealing station may include a separate sealing transfer wheel that receives the pouches and feeds the sealing jaws. In its path into the sealing conveyor wheel, the pouches are preferably connected to a packaging material, wherein the packaging material can guide the pouches with its folds which connect two opposite legs of the packages, wherein during the removal movement of the pouches from the conveyor wheel the pouches and the packages are moved relative to one another and brought into the sealing conveyor wheel in their final arrangement relative to one another and positioned there, and sealing is carried out in a generally known manner, wherein the legs are joined, typically sealed at the edges and ends around the pouches to produce aroma-tight packets. Thus, it is necessary that the film aroma hermetically seals the pouch.

Typically, the hose section is inserted into the support at the insertion station in a strictly radial direction, so that the chamber extends strictly radially with the bottom closest to the axis of rotation and the head furthest away from the axis of rotation. In view of this, according to a preferred further development of the invention, a removal station is proposed in which the support is pivoted by about 180 ° relative to the arrangement of the insertion station and the pouches are radially removed from the transfer wheel with the bottom in front. A removal station is usually associated with the pouch handling device and the packaging material handling device, which on the one hand removes the pouches radially from the transfer wheel and on the other hand grips the packaging material in a central region thereof in order to form folds there and insert them into the seal holding wheel in front of the pouches. The pouch handling device holds the pouch and inserts it into the sealing station.

According to another preferred configuration of the invention, a label supply station, in which labels are supplied to the heads, and a connection station, in which the thread is connected to the labels and/or the pouches, are provided between the insertion station and the removal station. In both stations, the pouch is held in the support so that the head is radially outward so that the label can be applied against the head and the label can then be attached to the pouch. The thread may be on a label or on a pouch. Preferably, the pouches are inserted into the transfer wheel together with the thread already in the insertion station.

According to a preferred further development of the invention, a thread-securing station is provided between the insertion station and the removal station, said thread-securing station being immediately upstream of the removal station in the conveying direction of the conveying wheel. The conveying direction corresponds to the direction of rotation of the conveying wheel. In the thread securing station, during further processing of the pouch, the thread already connected to the label is secured to the label such that the thread is secured in a predetermined position relative to the actual pouch and label. For this purpose, the labels usually have a slit into which the thread is pressed in a thread-fastening station. By suitable shaping of the label or pouch, the label itself can be secured in place relative to the pouch. The pouch and the corresponding support holding the pouch in place are pivoted about 90 +/-10 deg. relative to their position in the insertion or removal station. Contrary to the positioning of the support in the insertion or removal station, the position of the support and thus of the part of the device acting on the pouch (in this case the device for securing the thread to the label) is oriented to the extent required to pivot the support in the direction of the positioning already in the removal station in the path to the removal. This allows the removal station to be arranged as the last station in the conveying direction before the removal station and allows the device to be made more compact or the process to be performed on the conveying wheel for completing the pouches and threads together with the labels as a packaging unit contained in the packages to be made more rapid. According to a corresponding further development, the support rests in its main extension direction in the line fixing station, and therefore the insertion direction of the pouches is substantially tangential to the rotation axis of the transfer wheel.

According to another preferred configuration, which allows for the fastening of the supports and for the pivoting movement of the pockets or the supports for the pockets, the transfer wheel for each support has a hole in which the axle beam carrying the support is pivotally mounted. By attaching the support to the transfer wheel, the support is safely carried along with the transfer wheel. Bearings, for example ball bearings, can be assigned to the bore, which reliably guide the pivoting movement of the axle beam and thus the support relative to the transfer wheel with low friction.

In a further development described herein, at least one guide arm extending transversely to the pivot axis of the axle beam is decoupled from the axle beam. The guide arm is fixedly connected to the axle beam. The free end of the guide arm is guided in the flapper guide. The guide is guided by a small gap. For this purpose, the guide arm usually has a roller, which is referred to as a cam roller and forms a rotationally symmetrical and freely rotatable outer circumferential surface of the free end. The cam roller is accommodated in the guide groove. The guide groove is formed generally circumferentially closed in the stationary guide disk. The engagement of the free end of the guide arm in the slotted guide thus determines the relative angular positioning of the axle beam and the transfer wheel. The slotted guide is used to characterize the pivotal movement of the support during rotation of the transfer wheel.

The slotted guide is thus configured circumferentially about the rotational axis of the transfer wheel. In the case of a 360 ° rotary movement of the transfer wheel, the support is positioned in the insertion station thanks to the slotted guide, so that the portion of the support that is configured to the bottom of the pouch rests radially inside, while this portion rests radially outside in the removal station.

The axle beam preferably has at least two and particularly preferably exactly two guide arms with free ends, each of which is guided individually in a slotted guide. If more than one guide arm is provided, the free ends of the guide arms usually project to different extents in the direction of the axle beam, so that one free end is guided in a guide groove which, with respect to the pivot axis of the axle beam corresponding to the axis of rotation of the transfer wheel, is lower than the other guide groove assigned to the other guide arm. By increasing the number of slotted guides, the positioning and furthermore the guiding of the support in the case of a rotational movement of the transfer wheel is improved and a pivoting movement of the support of more than 90 degrees can be achieved.

To secure the pouch in the support, a pouch clamp may be provided that may be pivoted to an open position to insert and remove the pouch from the support, but otherwise rest against and secure the pouch in the support. In the position of affixing the pouch, the pouch clamp may be applied against the pouch under spring preload of the clamping spring. The bag clamp may for example be attached to an actuating sleeve which is mounted relative to and on the axle beam such that the actuating sleeve can pivot. The actuating sleeve can have an actuating arm which in each case interacts in the region of the insertion and removal stations with an opening cam which is stationary relative to the rotational movement of the transfer wheel and which pivots the actuating sleeve and thus the bag gripper against the force of the gripper spring and thus releases the bag gripper for removing or inserting a bag from or into the support. To reduce friction, the opening cam usually interacts with a cam roller mounted freely rotatably on the free end of the actuating arm. The opening cam typically guides the actuator arm until the pouch clamp is closed so that the pouch clamp is guided and applied to the surface of the pouch or restraining support.

Detailed Description

Fig. 1 shows an embodiment of a packaging unit, designated by reference numeral 2, consisting of a package 4 in which a pouch 6 with a thread 8 attached to the head 7 of the pouch 6 and a label 10 attached to the head 7 of the pouch 6 and thus opposite the bottom 9 of the pouch 6 (this pouch is in the form of a dual-chamber pouch) are accommodated. The thread 8 is knotted to the tag 10 on one side and passes through the slit 12 of the tag 10 on the other side and is thus secured to the tag 10. The contents of the package are thus produced on a transfer wheel as described below.

The wrapper 4 consists of a length of flavour-occlusive film which is folded over the fold 14 to form two adjacent legs 16 and sealed by two parallel longitudinal welded seams 18 and one transverse welded seam 20.

The accomplishment of the accommodation of the pockets 6 together with the labels 10 in the packages 4 is carried out on a transfer wheel as described hereinafter with reference to fig. 2 and the following figures, which are identified in the figures by reference numeral 100. In the views according to fig. 2 and 3, the transfer wheel 100 rotates counterclockwise. The direction of rotation corresponds to the transport direction T. The various stations are disposed circumferentially around the transfer wheel 100, wherein the pouches 6 or threads 8 or labels 10 are processed in the stations. An insertion station is provided with reference numeral 102, in which the pouches 6 are inserted into the transfer wheel 100 together with the thread 8 to which they have been attached. To this end, the transfer wheel 100 has a support 104 as shown in detail in fig. 3 to 7, which support comprises a support tube 106 receiving the pouch 6, to which a pouch gripper 108 is assigned, which holds the pouch 6 in the support 104.

As shown in fig. 2, the support conduit 106 in the insertion station 102 is positioned fully radially such that the pouch 6 may be inserted into the support conduit 106 by being radially tucked into the support 104.

Fig. 2 shows arcuate insertion sections 110 that move alternately to insert the pouches 6 into the respective supports 104. In each case, the rotation of the transfer wheel 100 is intermittent. Thus, during further processing of the pockets 6, the transfer wheel 100 is driven to rotate cyclically, wherein the transfer wheel 100 is stationary during the respective processing step.

Adjacent to the insertion station 102, in the transport direction T, there is a label feeding station 112 in which the cut labels 10 provided with holes and slits for the passage of the thread 8 are fed to the head 7 of the pouch 6. The support 104 has a radial orientation that is unchanged from the orientation in the insertion station 102. The same applies to the joining station 114 joined in the conveying direction T, in which the thread 8 is knotted to the label 10 in this embodiment, as substantially described in EP 1731295B 1.

After the connecting station 114, the support 104 is pivoted such that this support 104 is pivoted by 90 ° in the line consolidation station identified by reference numeral 116 and thus extends tangentially with respect to the axis of rotation D of the transfer wheel 100. In the thread affixing station 116, the thread 8 is inserted into the slit 12 of the label 10. In this way, thread 8 is configured to label 10 and then to pouch 6, so as to prevent the thread from interfering with the sealing of the edges of the wrapping material during the wrapping of the subsequent pouch, or even from being caught on parts of the device during the handling of pouch 4 together with label 10 and thread 8.

The removal station is identified by reference numeral 118. In said removal station 118, the pouch 6 is rotated by about 180 ° with respect to its orientation in the insertion station 102. Although the pouch 6 in the insertion station 102 is inserted into the support 104 with its bottom 9 leading, the pouch 6 is pushed out with the bottom 9 leading as the pouch 6 is pushed out radially in the removal station 118.

Between the removal station 118 and the insertion station 102, a pivoting station 120 is located downstream of the removal station 118 in the conveying direction, in which the support 104 is pivoted through approximately 180 ° so that it is positioned sufficiently for receiving a new pouch 6 in the insertion station 102.

As can be seen in fig. 3, the pouch 6 in the removal station is gripped in the support 104 by the pouch handling device 122 and pulled radially out of the support 104. For this purpose, the bag handling device 122 has front and rear arms 124 which grip the bag in the region of the base 9 and pull it radially out of the support 104 (see fig. 2). The front and rear arms (not shown in fig. 3) of the packaging material handling device 126 are placed in front of said arm 124, which grip the packaging material passing through the conveyor wheel 100 cut at the packaging material guide 130 to form and discharge the folds 14 radially. In fig. 3, in addition to the transfer wheel 100, a sealing transfer wheel 132 of the sealing station is shown, which receives the packages 4 together with the pouches 6, the thread 8 and the labels 10, wherein the material of the packages 4 has been provided with a fold 14 and a transverse edge opposite the fold 14, and two longitudinal edges are provided by sealing means which are substantially opposite the transfer wheel 100 with respect to the axis of rotation D of the sealing transfer wheel 132, and correspondingly the pouches 6 are hermetically sealed together with the labels 10 and the thread 8.

Fig. 2 and 3 show the cyclically pivoted radially inward opening cam 134 pivoting the pouch gripper 108 to an open position for insertion of a pouch 6 in the insertion station 102. At the removal station 118, an outer opening cam 136 is shown, which also does not rotate with the transfer wheel 100, and which is attached to a pivotally operated lever and lifts the pouch gripper 108 from the pouch 6 for removal of the pouch in the removal station 118.

Fig. 4 to 7 show details of the support 104.

Each support 104 has an axle beam 150 which is freely rotatably held on the transfer wheel 100 by means of ball bearings 152 which are placed in holes 154 (see fig. 3) of the transfer wheel 100 and mounted there. At the free end of the axle beam 150 there is a support tube 106 in which the bag holder 108 is pivotally mounted. The pivot axis for the pivotal movement of the bag clamp 108 is identified by reference numeral 156. The bag clamp 108 is non-rotatably connected to an actuating sleeve 158 which is held pre-tensioned against the axle beam 150 by a clamping spring 160. A retainer 162 is provided which is non-rotatably connected to the actuating sleeve 158 and carries at its free end an air knotting block 164 which projects partially beyond the opening of the support conduit 106 and in any case partially blocks the opening of the support conduit 106. In the closed position according to fig. 6, a hold-down spring 166 can be seen, which interacts with the free end of the pouch clamp 108 to keep it pre-tensioned against the pouch 6. In the open position according to fig. 4, the hold-down spring 166 is inside the receiving cylinder 168. In the open position according to fig. 4, the bag holder 108 abuts against the upper wall of the support tube 106 in fig. 4. Opposite the pouch clamp, a guide projection 170 projects from the opening of the support tube 106, the guide projection being outwardly inclined in a funnel shape.

An actuating arm 172, which is firmly connected to the actuating sleeve 158, projects radially from the actuating sleeve 158 and is provided at its free end with a cam roller 174. The cam roller 74 interacts with the guide surfaces of the inner and outer opening cams 134, 136. Thus, the pouch clamp pivots into the open position against the force of the clamp spring 160 and the hold down spring 166. Without the interaction between the cam roller 174 and the cam profile of the opening cam 134 or 136, the pouch clamp 108 pivots into the closed position shown in fig. 6. One end of the clamping spring 160 is supported on an actuator arm 172 (see fig. 5, 7).

At the end of the axle beam 150 opposite the support guide tube 106, two guide arms 176, 178 are provided, which extend radially with respect to the central longitudinal axis of the axle beam 150 and project in the axial direction through guide pins 180, 182 (each carrying a cam roller 184). Thus, the guide pin 182 has a greater axial extension than the guide pin 180.

Each guide pin 180, 182 engages in a respective guide groove, which is recessed in a guide disc, which is arranged in a fixed position behind the transfer wheel 100, according to the top view in fig. 2 and 3. The guide groove configured to the guide pin 182 is deeper than the guide groove configured to the guide pin 180. The grooves cross each other. They receive the cam rollers 184 of the guide pins 180, 182 through a small gap. Like the cam roller 174, the cam roller 184 also has a freely rotatable annular surface which is guided in the corresponding guide groove and can be brought into contact with the side wall of the groove with little friction.

Due to the rotatable mounting of the axle beam 150 via the ball bearing 152 opposite the rotating transfer wheel 100 and the two guide pins 180, 182 arranged eccentrically to the pivot axis of the support 104 (formed by the central longitudinal axis of the axle beam 150), a pivoting movement of the support 104 relative to the stationary guide disc within the range of the rotating movement of the transfer wheel 100 can be generated and precisely specified.

The configuration with two guide pins 180, 182 allows for a close and precise active guidance of the pivoting movement of the support 104. According to the top views shown in fig. 2 and 3, a total of six stations are provided in the circumferential direction of the transfer wheel 100. Thus, each support 104 is offset by 60 ° in the circumferential direction. Thus, the support 104 may be pivoted about 180 ° on a 120 ° conveying path, or just about 90 ° on a conveying path corresponding to 60 °.

In this embodiment, the rotational movement of the transfer wheel 105, together with the cyclical movement of the inner opening cam 134, causes the opening and closing of the bag gripper 108 in the area of the insertion station 102. In the removal station 118, opening and closing of the bag gripper 108 is effected by pivoting the outer opening cam 136 while the transfer wheel 100 is stationary. Thus, as shown in FIG. 3, the pouch clamp 108 is applied to the pouch 6. The holder 162 is held in a central position so that the continuously fed material forming the label 10 can be cut in the region of the label supply station 112 without colliding with the holder 162. When the transfer wheel 100 is stationary, the inner opening cam 134 pivots relative to the transfer wheel 100. However, as the transfer wheel 100 rotates, it also pivots against that direction of rotation.

The labels fed in the label feeding station 112 are placed against the outer surface of the air knotting block 164 which, together with the equipping section of the connection station 114, forms an air channel to guide the free end of the thread 8 to knot the thread 8 to the label 10, as described in EP 1731295B 1.
