Manufacturing method of rotary structure type sealing machine

The invention relates to a sealer of the rotary structure type for a container with a screw cap. The sealer comprises a load-bearing element fixedly assembled in the center, and at least one rotating loader having a plurality of seal assemblies can be surrounded by a first motor The carrier element is arranged in a rotary drive. The sealing assembly has a sealing tool which can be raised and lowered and can be rotated by a second motor, the sealing tool having a sealing head for receiving a screw cap on its lower side. Instead of a motor, for example an electric motor, all other types of drives can also be used.



Background technique:

Instead of a motor, only a driving pinion can be arranged on the sealing machine, the driving pinion is driven by a motor or a driving device that drives one sealing machine or multiple separate sealing machines at the same time. This machine also has a top plate connected to the load bearing element and a non-rotating control chute fitted on the carrier element and / or the top plate for raising and lowering the closing head when the seal assembly is swiveled around the load bearing element. The two motors can be controlled independently of each other, so that the speed of the sealing machine itself can be adjusted on the one hand, and the speed of the sealing tool can be adjusted independently of each other in the sealing assembly. The two motors each have a drive gear for interaction with a ring gear on the sealer. A sealing machine of this type is known, for example, from wo2012 / 163449a1.

Although the functioning of this sealing machine is satisfactory, disadvantages arise when the individual components are replaced and the sealing machine is therefore to be disassembled.



Technical realization elements:

The task of the present invention is therefore to further develop a sealing machine of this type, so that the sealing machine is of compact construction and can be easily disassembled from above. This sealing machine is described by the features of claim 1. Advantageous developments of the invention are the subject matter of the dependent claims. Advantageous developments of the invention are also described in the description and the drawings.

According to the invention, the task in a sealing machine of the type described above is solved in that the load-bearing element comprises a lower load-bearing element, which is connected at its upper end to an intermediate load-bearing element, which constitutes a bearing section and has At least one rotary bearing for rotating the carrier. The lower bearing element can be configured as a long column with a circular or polygonal cross section, which preferably carries a flange on its upper side, on which the intermediate bearing element forming the bearing section is screwed.

The intermediate load-bearing element is detachably connected to the upper load-bearing element, which in turn is detachably connected to the top plate. In this way, the sealing machine can be disassembled gradually from above, ie from the top plate, while the space above the sealing machine required for disassembly can be kept relatively small. For example, this space does not have to be much higher than the upper carrying element. The rotation axis of the drive gear of the first motor is oriented parallel to the machine axis and meshes with a ring gear formed on the rotating carrier. In this way, the driving force of the first motor or the first driving device can be easily transmitted to the rotating carrier.

The second drive gear of the second motor is also oriented parallel to the machine axis and meshes with a second ring gear formed on the control element. Therefore, the drive part runs parallel to the machine axis and can also be easily removed when the sealing machine is disassembled, which is also simplified by the following means: As a mutually-fitting drive element, a drive gear of a drive device or a motor is separately connected to the rotation load. A ring of gears or control elements work together. These drive parts can be easily completely separated from each other.

The sealing machine according to the invention is used in particular for the closure of screw-cap bottles made especially of glass and pet bottles. The sealing machine can be manufactured very compactly and can be easily disassembled and reassembled, wherein the drive components of the drive device which interact with one another can also be easily disassembled and connected to one another. As a result, individual components that are susceptible to wear can be easily and quickly replaced.

Preferably, the shaft guide of at least one of the two motors extends parallel to the machine axis, which automatically causes the mutually interacting drive components to be dismantled when the top plate or the upper carrier element is removed. In this case, the shaft guide protrudes to the height of the intermediate carrier element and drives the respective ring gear by a corresponding drive gear arranged at the end.

In an advantageous embodiment of the invention, the top plate is detachably connected to the upper carrying element, so that the sealing machine can be removed in a simple manner from above, ie from the top plate.

Preferably, the intermediate load-bearing element (that is, the bearing section for the rotating load) is detachably fixed to the lower load-bearing element, which is preferably configured as a longer load-bearing column. This has the advantage that the sealing machine can be disassembled from above, probably up to the vertical height of the rotating carrier or container carrier, without having to dismantle a relatively long load column corresponding to the lower load element. Therefore, the space for assembling and disassembling the sealing machine is significantly smaller than the prior art.

In an advantageous development of the invention, the upper, middle and lower load-bearing elements can be removed from the top plate by means of a detachable connection, such as a screw connection.

This simplifies the disassembly of the different load-bearing elements of the sealer and therefore simplifies the disassembly of the individual drive components, such as drive shafts, shaft guides, drive gears or ring gears that interact with drive gears of motors or drive units, which are usually There is wear and tear. By arranging the rotary bearing for the rotary carrier and preferably the control element on the intermediate carrier element, the intermediate carrier element is preferably detachably held on the lower carrier element, and the equally worn rotary bearings for these components can also be easily made. Ground replacement.

Preferably, the control element is rotatably supported on the upper carrier element and / or on the rotary carrier, whereby it can be supported in an efficient manner without a large lever force. In this case, the control element is preferably supported on a rotary carrier, which has the advantage that only the intermediate carrier element must carry the first rotary bearing for the rotary carrier, and no further rotation must be supported by the lower, middle or upper carrier element Bearings. Thus, the entire support is provided on the intermediate load bearing element or bearing section, whereby both rotating bearings (for the rotating load bearing and for the control element) can be arranged on one component and can therefore be easily replaced .

Preferably, the upper load-bearing element surrounds an internal space containing the machine axis, and at least most of the drive gear of the first motor is arranged in the internal space. Therefore, the drive shaft or shaft guide of the first motor can extend in the internal space, and thus, the entire vertical section, that is, the vertical section including the mechanical axis, can be provided with a driving member, so that the sealing machine can be integrated. The structure is very compact. The drive shaft of the first motor can be arranged in the internal space, so the two drive shafts of the two motors for rotating the carrier and the control elements can be easily separated, wherein the drive gear of the first motor is preferably arranged at In the internal space, and the drive gear of the second motor is preferably arranged in an annular space between the upper bearing element and the outer toothed ring of the control element, which outer toothed ring interacts with the outer toothed portion of the sealing tool.

What is to be implemented in this case is that the rotary drive of the sealing tool is preferably achieved by the following: the drive gear of the second motor interacts with the ring gear of the control element, and the control element has an external ring gear / external tooth portion, which The ring gear / outer teeth mesh with the outer teeth of the sealing tool on the sealing assembly. In this way, the rotational speed of the sealing head held on the sealing tool can be adjusted independently of the rotational speed of the sealing machine, ie the rotary carrier.

Preferably, the upper carrying element is open on a machine sector in which the drive gear of the first motor meshes with the ring gear of the rotating carrier. Because the driving gear of the first motor is arranged in the internal space of the upper bearing element, that is, surrounded by the internal space, it is required that the upper bearing element is open at least in one sector, so that the first motor's The drive gear can interact with a ring gear on the rotating carrier. This is possible in particular when the upper load-bearing element is formed by a plurality of parallel load-bearing struts, which are preferably arranged at the same distance from the machine axis and around the machine axis. Accordingly, the shaft guide of the first motor preferably also extends in the internal space surrounded by the upper carrier element.

As already described, the rotational drive of the sealing tool is preferably ensured by a control element, which is rotated by a second motor, and which interacts with the external teeth of the sealing tool.

The up and down movement of the sealing tool that finally carries the sealing head with the screw cap is preferably achieved by a rotor on the upper side of the sealing tool, which rotor runs along the control chute of the sealing machine and deflects upward or downward corresponding to the control curve. Therefore, the sealing tool and thus the sealing head can be moved up and down in any way and can be rotated.

In an advantageous development of the invention, the lower carrier element is connected to the bearing section in particular in the area of 0 to 40 cm, in particular 5 to 30 cm, below the rotary carrier or below the container carrier, in particular by means of a screw flange. This has the advantage that the detachable height of the sealing machine only extends on the vertical section from the top plate to the rotating carrier or container carrier, and does not include the usually very long load-bearing columns that constitute the load-bearing element. Thus, the lower load-bearing element can be, for example, a column having a circular or polygonal cross section.

In an advantageous embodiment of the invention, both motors are fixed on the top plate, from which the shaft guides of the motors extend vertically and axially parallel to the machine axis downwards to the corresponding drive gear. This allows the drive components of the two motors or drives to run parallel to the machine axis and therefore can be easily disassembled together from above when disassembling the sealing machine.

Preferably, the shaft guide or drive gear of the second motor extends into the annular area between the upper load bearing element and the sealing assembly, so that the driving members of the first motor and the second motor cooperate with different diameters relative to the machine axis They are arranged at a distance and can thus be easily disassembled.

It is clear to a person skilled in the art that the above embodiments can be combined with each other in any desired manner.

In this application, the following terms are used as synonyms: motor-drive; drive gear-drive pinion; container-bottle; control element-drive element for the closure assembly.

detailed description

The sealing machine 10 is composed of a lower load-bearing element 12 in the form of a polygonal load-bearing post at its center containing the machine axis, and a spiral flange 14 is arranged at the upper end of the load-bearing post. An intermediate load bearing element 16 is screwed on the spiral flange 14, and a first rotation bearing 38 for rotating a load bearing element 32 is arranged on an outer peripheral surface of the intermediate load bearing element. The rotating load bearing element bears a plurality of sealing components on its outer circumference. 56. An upper load-bearing element 18 is screwed onto the intermediate load-bearing element 16. The upper load-bearing element is composed of a plurality of vertical load-bearing pillars 20, which are arranged at equal intervals around the machine axis. These load-bearing struts 20 form an internal space 64 on the side they point towards the machine axis. On the upper side of the supporting pillar, the supporting pillar 20 is screwed with the top plate 22 by means of fixing bolts 23. The top plate 22 carries a first motor 24, and the shaft guide 26 of the first motor runs in the internal space 64 between the supporting pillars 20. A drive gear 40 is arranged on the lower side of the shaft guide 26 and meshes with a ring gear 42 which is connected in a rotationally fixed manner to a rotating carrier 32. In this way, the rotary carrier 32 and the sealing assembly 56 thus arranged on its periphery are rotated by the first motor 24 at an adjustable speed.

The top plate 22 also carries a second motor 28. From this second motor, the shaft guide 30 is guided downward to the drive gear 48 of the second motor 28. The drive gear meshes with the ring gear 50 on the control element 46. The ring gear 50 shown is an internal ring gear, but can also be configured similarly as an external ring gear, wherein the shaft guide and the drive gear must accordingly be arranged radially outside, as shown in FIG. 3.

The control element 46 is supported on the rotary carrier 32 by means of a second rotary bearing 44. Thus, the control element 46 can be rotated independently of the rotary carrier 32, however, the control element is supported on or at the rotary carrier. The control element 46 has an external toothed portion or ring gear 54 which meshes with an external toothed portion 60 on the sealing tool 58 of the sealing assembly 56. In this manner, the sealing tool 58 of the sealing assembly 56 is controllably rotated by the second motor 28, whereby the rotation is transmitted to the sealing head 58 disposed on the lower end portion of the sealing tool 58, which sealing head The section carries the screw cap. The rotary carrier 32 is connected to the container carrier 34 by a connecting element 67 in the form of a vertical strut, which container carrier has a container receiving portion 35 for the container 66 on its outer periphery, so that these container receiving portions are by means of the container carrier 34 is held below the sealing assembly 56, that is, below the sealing head 59.

The sealing tool 58 is connected on its upper side to a rotor 62 which runs along a control curve of a control chute 52 which is connected in a rotationally fixed manner to the top plate 22 and / or the bearing strut 20. In this manner, the sealing tool 58 and the sealing head 59 are moved up and down with the sealing tool in a defined manner so as to thereby place the screw cap on the container 66 during the sealing process and securely screw it.

As a result, the sealing machine 10 according to the present invention can be easily disassembled from its top plate 22, and with the top plate 22 and the upper carrying member 18 or 20 removed, the first motor 24 and the rotating carrier can also be easily disassembled. 32 drive components 26, 30, 40, 48 that interact with one another and with the control element 46 that interact with the second motor 28. Therefore, the sealing machine 10 according to the present invention can be easily disassembled, and various components of the sealing machine can be replaced in a simple manner. The above embodiments of the present invention should not limit the protection scope of the present invention in any way. Instead, the invention can be implemented within the scope of protection of the following claims.

The helical flange 14 at the upper end of the lower load-bearing element 12 is located approximately vertically in the region of the rotating carrier 32, ie within a vertical distance of a maximum of 30 cm. This makes it unnecessary to take into account the generally relatively large length of the load-bearing elements for the space when disassembling the machine 10. Through the present invention, all the main components of the sealing machine 10 can be removed from the top plate 22 to the flange 14, wherein it is not necessary to remove the long lower load-bearing element 12 in the form of a bearing column to access all the important parts of the sealing machine 10 component.

A sealing machine is shown in detail in FIG. 3, which is largely similar to the construction according to the variant of FIGS. 1 and 2. The main difference is the drive implemented by the motor 28.

According to FIG. 3, the top plate 22 carries a similar second motor 28 (not shown) from which the shaft guide 30 extends downward to a drive gear 48 which meshes with the ring gear 50 at the control element 46 . The ring gear 50 shown is an outer ring gear, wherein the shaft guide 30 and the drive gear 48 are arranged radially outside for this purpose.
