Technical Field

The present invention relates to a conveyor bowl having the features of the preamble of claim 1. The invention also relates to a vibrating conveyor device with the conveyor bowl and a method for manufacturing the conveyor bowl.

Background

Vibratory conveyors move parts or materials by oscillations or vibrations that act on the conveyor structure on which the parts or materials are disposed. The oscillation or vibration is set such that the components or materials are transported with low friction in the transport direction and under frictional load when the vibrating conveyor moves in the opposite direction on return trip, so that the movement of the components or materials in the direction opposite to the transport direction is suppressed. Thus, in each stroke at least one component of the movement remains in the conveying direction, so that the components or material are transported in the conveying direction.

For example, document EP 0936162 a1 discloses a vibrating conveyor with a laterally mounted drive, which has a conveyor structure for transporting the material to be conveyed and which is made of metal.

Disclosure of Invention

It is an object of the present invention to propose a conveyor bowl for a vibrating conveyor device, which conveyor bowl has good functional properties and/or can be manufactured in a repeatable manner.

This object is achieved by a conveyor bowl having the features of claim 1, by a vibrating conveyor device having the features of claim 9 and by a method having the features of claim 10. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and the drawings.

The present invention relates to a conveyor bowl adapted and/or designed for use in a vibrating conveyor device. The function of the conveyor bowl is to collect the material to be conveyed and move it along the conveyor track. This movement takes place by means of oscillations or vibrations which are generated by a vibration unit of the vibrating conveyor device and which act on the conveyor bowl. In the most general form of the invention, the product being conveyed may be in the form of a material, in particular in the form of a bulk material, or as a component or as any object being conveyed. Particularly preferably, the products to be conveyed are formed such that each conveyed element of the conveyed products has a maximum dimension of less than 3 cm.

In addition to such a transport function, the conveyor bowl may also perform an alignment and/or sorting function for conveyed products, in particular for conveyed pieces, by aligning the conveyed products on the conveyor track such that they issue at the ends of the conveyor track in an aligned and/or ordered and/or position-defined manner. For this purpose, the conveyor bowl may have structural features and/or means that result in alignment of the conveyed product. Such measures are generally known from the prior art.

The conveyor bowl has a metal body with an engagement portion for coupling to a vibratory unit. The coupling can be performed directly; alternatively, an intermediate part, in particular an adapter part such as an intermediate plate, may be provided between the conveyor bowl and the vibration unit. The main body also has a conveyor section for conveying the products to be conveyed, in particular the conveyed pieces. In particular, the conveyor section forms a conveyor track of the conveyor bowl.

In the context of the present invention it is proposed that the body is made of stainless steel and is manufactured via one-shot forming. Stainless steel, in particular stainless steel according to EN 10020, means alloy or non-alloy steel of a specific purity, such as steel in which the sulphur and phosphorus content (so-called impurities) does not exceed 0.025% (mass fraction). Stainless steel is particularly preferably designed to be rust-proof.

An advantage of this embodiment is that the conveyor bowl has very good functional properties, since it is very wear resistant and therefore very resilient due to the stainless steel material. The conveyor bowl can be manufactured in a very repeatable way due to the manufacturing via one-shot forming. Furthermore, especially in the case of large numbers, cost advantages can be achieved compared to complex mechanical structures, for example made of steel sheet. Another advantage is that care is taken to ensure that no blind holes, gaps or similar dead spaces are formed, even during construction of the conveyor bowl, in which the conveyed product may become stuck or permanently stuck, or in which dust particles may accumulate.

In a preferred development of the invention, the stainless steel is realized as stainless austenite, in particular austenite without addition of sulfur (e.g. 1.4301 or 1.4307 or 1.4404 or 1.4571). The selection of stainless steel, which is stainless, ensures that the conveyor bowl is suitable for food and/or can be approved for use with food products. Particularly preferably, the conveyed product is provided as a food or as a conveyed piece which has to meet the requirements applicable to the food industry. The conveyed product particularly preferably forms part of a conveyor bowl and/or a vibrating conveyor device.

In a preferred embodiment of the invention, the body is designed as a casting, in particular as a precision casting. The first step in precision casting is to make a model of the subsequent mold. In a subsequent step, the pattern is immersed in a slurry, in particular a ceramic slurry, possibly several times, so that sand is sprinkled onto the resulting casting mould between the immersion process. This process is repeated until the mold has the desired stability. The casting process is particularly preferably carried out using the gravity method. This results in the conveyor bowl being formed with the bottom facing upwards and/or the bowl opening facing downwards. The precision casting process also makes it possible to create undercuts in the conveyor bowl. For example, the conveyor bowl can be manufactured in a very repeatable way, since the manufacturing of the model can be performed with CAD-CAM support. Precision casting has particular advantages due to the particular surface quality, in particular low roughness in the region of the conveyor track due to the process.

In a preferred embodiment of the invention, the engaging part and the conveyor part are formed in one piece in the body, in particular from the same cast body part. This has the advantage that oscillations and/or vibrations can be transferred from the joint part to the conveyor part with little or no losses, without impedance transitions between the individual parts.

In principle, the conveyor bowl may have a straight conveyor section. However, it is preferred that the conveyor section has a helical conveyor track, in particular a conical helical, screw-like and/or spiral conveyor track. Alternatively or additionally, it is preferred that the rough shape of the conveyor bowl is designed as a shell, in particular the outer contour is designed as a rotationally symmetrical shell. The conveyor section may also have a plurality of such conveyor tracks.

The conveyor track particularly preferably extends from the bowl bottom to the bowl opening, the conveyor track preferably surrounds the main axis of the conveyor bowl several times, and the diameter of the conveyor track increases from the bowl bottom to the bowl opening, and the conveyor track can also be inclined outwards. The advantage of this configuration is that on the one hand conveyed products can be conveyed and on the other hand conveyor bowls with conveyor sections forming a conveyor track can be modeled particularly simply as castings, in particular precision castings, since undercuts are not present or at least reduced.

It is particularly preferred that the body has a wall portion which forms a lateral guide for the products to be conveyed along the conveyor track. In particular, the wall portion forms a guide extending radially outwards with respect to the main axis. It is provided that the wall portion is formed by the same cast body part as the engaging portion and/or the conveyor portion. The one-piece and/or integrated design as a casting further improves the mechanical stability of the conveyor bowl.

Another object of the invention relates to a vibrating conveyor device comprising a conveyor bowl and a vibrating unit, wherein the conveyor bowl is connected to the vibrating unit via a joint portion such that oscillations and/or vibrations can be transferred from the vibrating unit to the conveyor bowl.

The oscillating conveyor device is particularly preferably designed as a screw conveyor device, in particular as an oscillating screw conveyor device.

Another object of the invention relates to a method for manufacturing a conveyor bowl as described above or according to one of the preceding claims. The method comprises the step of manufacturing the body of the conveyor bowl via one-shot forming. In particular, the body is a casting, in particular a casting made by precision casting.

In a possible development of the invention, a functional prototype for the conveyor bowl is produced in a preparation step. This preparation step has the advantage that the correct operation of the functional prototype can be checked. The functional prototype is then captured in three dimensions and/or CAD modeled to generate a CAD model of the functional prototype. Starting from the CAD model, the CAD model for the conveyor bowl and/or body is then derived as a basis for the model for the precision casting. As an alternative to the preparation step, a CAD model of the conveyor bowl can be manufactured exclusively by construction and/or modeling. The advantage of the latter alternative is that the conveyor bowl can be designed specifically in a CAD program, so that no functional prototype has to be made.

Drawings

Further features, advantages and effects of the invention result from the following description of a preferred exemplary embodiment of the invention and from the drawings. In the drawings:

fig. 1 shows a schematic three-dimensional view of a conveyor bowl as a first exemplary embodiment of the invention, seen from below;

fig. 2 shows a schematic three-dimensional view of a vibrating conveyor device as another exemplary embodiment of the invention;

Fig. 3 shows a schematic three-dimensional view of a vibrating conveyor device as another exemplary embodiment of the invention;

fig. 4 shows a schematic three-dimensional view of a vibratory conveyor device as another exemplary embodiment of the invention.

Detailed Description

Fig. 1 shows a conveyor bowl 1 as an exemplary embodiment of the invention in a schematic three-dimensional view. The conveyor bowl 1 is designed as a circular housing. In this exemplary embodiment, the bowl bottom 2 is designed without a base or without a seat, so that a base opening 3 is formed.

The conveyor bowl 1 has a body 4, which body 4 is formed of a common part of material. In particular, the body 4 is formed in one piece and/or integrally.

From a constructional point of view, the body 4 has an engagement portion 5, which engagement portion 5 is used to couple the conveyor bowl 1 or the body 4 to a vibratory unit 6 which is part of a vibratory conveyor device 7, for example as shown in fig. 3 or 4. Vibrations and/or oscillations are introduced into the conveyor bowl 1 via the joint part 5 for transporting and orienting the conveyed products arranged in the conveyor bowl 1 along the conveyor track 8, as shown in fig. 2-4. The vibrating conveyor device 7 corresponds to a vibrating conveyor, in particular to a screw conveyor and in particular to a vibrating screw conveyor.

The conveyor track 8 is formed by a conveyor part 9, which conveyor part 9 is designed as a spiral rising from the bowl bottom 2 in the direction of the bowl opening 10. The course and extension of the conveyor track 8 can be formed by a radial vector which rotates about the main axis H and at the same time rises along the main axis H in the direction of the bowl opening 10, in particular also sloping outwards.

Furthermore, the conveyor bowl 1 and/or the body 4 has a wall portion 11, which wall portion 11 forms a radial boundary towards the outside for the conveyor track 8. From a constructional point of view, the wall portions 11 connect the respective helical regions of the conveyor section 9 in the vertical direction of the conveyor bowl 1 and/or the body 4.

The body has an axial rib 12 moulded thereon extending in an axial direction relative to the main axis H. The axial ribs 12 serve to increase the mechanical stability and/or rigidity of the conveyor bowl 1 and/or the body 4 and support the casting action.

The body 4 of the conveyor bowl 1 is made of stainless steel and can therefore be used for the transport of conveyed products in accordance with the regulations of the food industry. In particular, the steel is a stainless steel without added sulphur, such as 1.4301 or 1.4307 or 1.4404 or 1.4571 stainless steel. The body 4 is manufactured via a one-shot forming process, i.e. via casting. More precisely, this is a precision casting process. The melt is injected into the mold under gravity. For better mold release, the body 4 is positioned in the mold with the bowl opening 10 facing downward.

Fig. 2 shows the conveyor bowl 1 of fig. 1 or a similar conveyor bowl 1, in each case with the same reference numerals indicating the same parts, components, etc., as in the following figures.

In fig. 2, a spiral conveyor track 8 can be seen, which is formed as a surface on a conveyor part 9. The wall portion 11 can also be seen. In principle, the bowl bottom 2 may be integrally closed in the body 4 by a base part (not shown). For weight reasons, however, it is advantageous if the bowl bottom 2 is formed by a base 13 made of plastic.

In fig. 2, there can also be seen an intermediate plate 14, also made of plastic, which forms an adapter between the vibration unit 6 and the conveyor bowl 1. As an alternative thereto, the conveyor bowl 1 may also be directly connected to a vibration unit 6 for transmitting vibrations and/or oscillations. In terms of the operating mode, the products to be conveyed are transported along the conveyor track 8 to the output 15 as a result of the vibration and/or oscillation.

Fig. 3 shows an alternative embodiment of the vibrating conveyor device 7, which differs in particular in the dimensions of the conveyor part 9 and the wall part 11. Furthermore, the base 13 is designed to be larger than in fig. 2, and the intermediate plate 14 is also realized in a different manner. In the same way as before, the conveyor part 9 forms a conveyor track 8, which conveyor track 8 conveys the conveyed products from the base 13 to an output end 15 to which a material guide 16 is connected.

Fig. 4 shows another exemplary embodiment of a vibrating conveyor device 7, which in turn has a different conveyor bowl 1, which conveyor bowl 1 differs in the dimensions of the conveyor part 9 and the wall part 11. In the exemplary embodiment in fig. 4, the output 15 is connected to a material guide 16 which is designed as a linear conveyor and transports and/or orients the conveyed products.

Thus, a conveyor bowl 1 designed as a vibrating conveyor bowl and made of cast stainless steel is proposed, which is manufactured using a precision casting process. Advantageously, precision casting achieves precisely an average roughness depth Rz of less than Rz 6.5, in particular less than Rz 6.4, in particular according to DIN EN ISO1302, which results in that conveyed products, in particular conveyor bowls (felts, silicones, plastics, metals, etc.), can be conveyed more easily. In particular, the conveyor bowl is used to provide the feed of the conveyed element to machines and systems having the desired performance and/or in the correct position throughout the value creation chain. In particular, the vibration unit 6 and/or the oscillating conveyor device 7 are designed as a rotary oscillating conveyor. The conveyor bowl 1 is firmly connected as a drive to the vibration unit 6 so that the oscillations and/or vibrations can be transferred directly or indirectly to the conveyor bowl 1. The oscillation and/or vibration causes the conveyor bowl to move and enable its conveyance. It is also possible to manipulate the transport behavior entirely by means of a partial coating or lining. For example, attached, connected sorting means, such as grooves, may optionally be moulded on the body 4 or connected to the body 4 as an additional component. These sorting devices enable the conveyed articles to be transferred to subsequent machines or assemblies thereof having the required properties and/or being in the correct position.
