Description

Cutter with a circumferential seal

The invention relates to a cutter with a rotating bowl and a non-moving part, between which a seal is provided. Furthermore, the present invention relates to the replacement of such a seal.

Cutters are well known in the art. With these machines, food, especially meat and cheese, for example, crushed, mixed and / or emulsified. The cutter has a rotating bowl, which is often substantially toroidal in shape, with a motor driven knife shaft approximately tangential to the vertical torus axis of rotation carrying a knife head equipped with knives which chop the food in the cutter bowl and / crush and / or mix. Between the rotating bowl and a stationary part of the cutter, for example the frame, there is provided a gap provided with a seal

is completed. This seal is subject to wear and must therefore be replaced regularly, which was often time-consuming in the past.

The present invention therefore an object of the invention, a cutter and a

To provide a method which does not have the disadvantages of the prior art.

The object is achieved with a cutter with a rotating bowl and a non-moving part, between which a one- or multi-part seal is provided, wherein the seal has a connection, the at least two ends of the seal

connects with each other.

The statements made on this subject of the present invention apply equally to the other objects of the present invention and vice versa.

The present invention relates to a cutter, with the food, especially meat and cheese, for example, crushed, mixed and / or emulsified. The cutter has a rotating about a preferably vertical axis bowl, the

Foods takes and often has essentially the shape of a torus and on the outer periphery usually a substantially horizontal edge is arranged. Preferably, approximately tangentially to the torus axis, a motor-driven knife shaft is provided, which carries a fitted with knives or other tools cutter head, for example, chopping up the food in the cutter bowl. Between the rotating bowl and a stationary part of the cutter, for example, the frame, a gap is provided, which is closed with a seal, in particular so that no food gets under the bowl.

According to the invention, the seal has at least one connection which connects two ends of the seal. This allows the seal to be initially placed around the bowl without the ends being connected together. Then the ends are connected together. The seal can thus be mounted without removing the bowl from the frame, which greatly simplifies the replacement of the seal. Nevertheless, the seal is sufficiently dense and / or sufficiently stable in its shape and position.

Preferably, the connection between the two ends of the gasket is in a freely accessible area around the periphery of the bowl, which is outside the range in which the food is loaded or unloaded into the cutter and / or in which, as is typically the case, food with the gasket in Contact can come.

Preferably, the seal is made of a plastic material, such as a

rubber-like plastic material, in particular made of a rubber and / or silicone plastic material. Preferably, the seal has an elastic lip, which is particularly preferably applied to the rotating bowl and most preferably integrally with a base member, the foot of the seal,

is provided. Preferably, the seal is extruded.

The Width of this gap is preferably equal to or greater than or even smaller than the width that can take the seal minimally, and it can be reversibly compressed especially with a small gap. Thereby, the seal can be mounted through the gap, without a cover or the like must be dismantled, which facilitates the manufacture of the cutter, but in particular also the replacement of the seal. In very cramped places of the cutter, it may also be necessary to use, for example, spoon-like auxiliary tools for mounting support.

According to a further preferred embodiment of the cutter, the gap between the rotating bowl and the fixed part of the bowl drive, preferably the transmission, which is preferably arranged at the lower end of the bowl, sealed.

Another object of the present invention is a method for changing a seal of a cutter, wherein the seal between the bowl of the cutter and a non-moving part of the cutter, for example, the frame is arranged, in which the ends of the seal are joined together.

The connection of the two ends together takes place in particular after the seal has been wrapped around the bowl and has taken its final position.

For example, the ends are firmly bonded together.

Alternatively or additionally, the ends are positively and / or non-positively connected with each other, whereby the positive and / or non-positive connection takes place in particular reversibly.

Preferably, the seal is tensioned prior to joining the two ends.

Preferably, the seal is shortened prior to connection from the ends thereof. As a result, a unit seal can be made available for different cutter sizes, which is then adapted on site to the respective cutter.

Preferably, a recess is provided for mounting the seal in this then a fastening means is introduced. Preferably, the seal for the assembly is reversibly compressed.

In particular, for the assembly of the seal, the lip of the seal is applied to the foot of the seal. Particularly preferably, the lip of the seal after its assembly does not assume its original position, but is biased against the bowl.

Preferably, the seal is mounted by a freely accessible area between the cutter edge and the frame. This area preferably extends around the entire circumference of the bowl and is not covered by a sheet or other means. The distance between the frame and the bowl in this area is preferably greater than the width of the seal, in particular the width to which the seal is minimally compressible. Thereby, the seal can be mounted in this area, without the bowl, a cover or the like must be dismantled.

Preferably, one end of the seal is fixed to the frame of the cutter and the seal is then placed piece by piece around the cutter bowl until a complete circle is laid. Subsequently, the two ends of the seal are connected together.

The invention will be explained below with reference to the figures. These explanations are merely exemplary and do not limit the general inventive concept. The explanations apply equally to all articles of the present invention.

Figures 1-3 show a first embodiment of the cutter according to the invention. FIG. 4 shows a further embodiment of the cutter according to the invention. FIGS. 5-8 each show an embodiment of the connection of the two ends of the seal 4, 5.

FIG. 9 shows yet another embodiment of the cutter according to the invention.

FIGS. 10 to 11 each show an embodiment of the connection of the two ends of the seal 4, 5.

Figures 12-13 show yet another embodiment of the seal according to the invention, in which the ends of the sealing lip are connected to each other. FIGS. 1 to 3 each show a section of the cutter 1 according to the invention. The cutter has a bowl 2, which is designed, for example, torus-shaped. The bowl is rotatably driven about a vertical axis mounted on a frame 3. That too

product to be crushed and / or emulsified (not shown) is in the bowl 2. The product, in particular meat cheese or other food, is through

Cutting knife (not shown) comminuted and / or emulsified, which are located on a motor-driven cutter head. Between the frame 3 and the bowl 2, here the edge 2.1 of the bowl is provided around the entire circumference of the bowl extending gap 13, which is sealed by a seal 4, to avoid that product or cleaning liquid between the frame and the

Bottom of the bowl passes. The gasket 4 is arranged in the present case on a circumferential base 8, which is optional. The seal has in the present case a foot which rests against the frame 3 and here the base 8, to which an integral elastic lip 4.1 is provided, which is connected to the underside of the

Bowl edge and here with the bowl edge 2.1 sealingly cooperates. At the bottom, i. The side facing the frame, the bowl preferably has a circumferential projection 2.2, on which the lip can abut 4.1 and / or can protect the lip from mechanical influences. The lip 4.1 is preferably biased against the bowl. The optional base 8 is connected to the frame by means of the fastening means 9. In the present example, the freely accessible width B (see Figure 2) of the gap 13 is selected so that the seal 4 can be mounted by him. For this, the seal either has a width b which is smaller than the width B of the gap, or the shape of the seal is reversibly changeable so that the width of the seal is less than or equal to the width of the gap B, for example, by the lip 4.1 is pressed in the direction of the foot of the seal. As soon as the gasket is in the correct position, it at least partially reforms again into its original shape. Due to the design of the gap 13, the bowl for changing the gasket 4 does not have to be disassembled from the frame. The gap 13 is not covered by an apron or the like.

FIG. 4 shows a preferred embodiment of the cutter according to the invention. In the present case, the cutter has an internal seal 5, which is also provided between the bowl 2 and the frame 3. The seal 5 in the present case has a foot and a lip, with the foot resting on an optional base, which is arranged on the frame 3, supported. The seal 5 is particularly suitable for so-called cooking cutters, in which the bowl, for example, with a

Water bath, which is located below the bowl, is heated. The seal 5 Prevents water vapor from leaking between the frame and the bowl.

According to an embodiment of the present invention, the seal 4 or 5 is not provided as an endless seal, but has a connection 6, at which the two ends of the seal are assembled after the assembly of the seal. The connection 6 between the two ends of the seal can be positive and / or cohesive. It can be provided in the region of the connection 6 connecting means 7, for example in the form of a positive and / or non-positive means to accomplish the connection of the two ends and / or support. In the event that the seal has a foot 4.2 and a lip 4.1 arranged thereon, the connecting means 7 preferably extends only in the area of the foot 4.2.

Figure 5 shows a first preferred embodiment of such a connecting means 7. In the present case, the connecting means is designed in two parts, wherein in each case a part with one end of the seal, in particular with its foot, is connected. Each part of the connecting element is here made of a metal sheet, for example a perforated plate, one end of which is connected to the seal in a material-positive and / or non-positive manner. In this example, one end of the connecting means is provided in a T-shape and is connected to the gasket 4, in particular to its foot 4.2, for example by enclosing the respective end of the respective part of the material from which the gasket is made. At the opposite end, each part of the connection has a positive and / or frictional connection, each of which is complementary to one another.

For example, each end has a hook that can be hooked together for connection. To. Mounting the seal is placed around the bowl, with the ends of the seal are unconnected. After this process step is completed, the connecting means 7 are connected to each other, wherein the seal can be stretched. In addition, the connection of the two ends can be improved by a material bond in the region of the material from which the seal is made. This material connection then preferably extends to the foot and / or the lip of the seal.

Figure 6 shows yet another embodiment of the connecting means 7, which are preferably made of a perforated plate. In the present case, the ends of the parts connected to the gasket are not T-shaped, but they may be. One end of a part of the connecting element 7, in the present case at least one, here two, hook 1 1, which engages in a recess 10 of the other part and so creates a positive and / or positive connection between the two. In the embodiments according to FIGS. 7 and 8, the connecting element 7 is provided in one piece, wherein in the example according to FIG. 7 it is a bent part, in particular a U-shaped bent part. The connecting element may be made of metal or another, relatively rigid material. In each case one leg of the U is connected to the seal. For this purpose, the two ends of the seal each have a recess into which the leg is inserted after the seal has been placed around the bowl. In the embodiment according to FIG. 8, this is

Connecting means a pin whose ends are each inserted into one end of the seal. The ends of the pin may include means which improve the positive and / or frictional connection between the connecting means and the seal.

FIG. 9 shows a further embodiment of the cutter according to the invention. In the present case, a seal 4 is provided between the cutter bowl 2 and the transmission 14, which is provided on the frame 3 and forms part of the rotary drive of the cutter bowl. The foot of the seal is attached to the frame of the cutter. The sealing lip 4.2 is located on the cutter bowl 2, in particular on a projection 2.2 of the annular ring at the bottom of the cutter bowl is provided at. The gap 13 between the cutter bowl and the frame is in turn provided so that the seal 4 can be mounted by him. The gasket is again preferably a gasket with a joint connecting the two ends of the gasket together. Thus, the seal can be mounted without the cutter bowl 2 is lifted from the frame, which greatly simplifies this work. The seal is replaced by removing the old seal, preferably separating it, and then placing a new seal around the frame. Once the two ends of the seal are opposite, they are connected together. If necessary, the seal is shortened beforehand. The entire assembly takes place through the gap 13, so that the cutter bowl does not have to be raised.

Figures 10 a - c show yet another embodiment of the seal 4, 5, which has a connection point 6 in the mounted state. In the present case, the seal optionally has a thickening in the connection region. As can be seen in particular from FIGS. B and c, one end of the seal has a pin which can be positively and / or materially connected to the seal. This pin has a locking means 18 which preferably extends fully around the pin. To connect the two ends of the seal of the pin is inserted into a sleeve which is positively and / or cohesively connected to the other end of the seal 4, 5. During insertion, the locking means engages a corresponding forward or return in the sleeve. These Compound is preferably irreversible. For disassembly, the seal is cut, for example.

FIG. 11 shows yet another embodiment of the gasket 4, 5. In particular, FIG. can be removed, the seal also has a pin which has an extension of its circumference at one end, which is latched to a corresponding recess in the other end of the seal. For assembly, the two ends of the seal are brought together, but slightly offset from each other, so that the two ends are side by side. Then, the two ends are moved parallel to the connecting surface or parallel to the longitudinal extent of the pin until the pin is locked in the corresponding recess. Also this connection is irreversible.

In the embodiment according to FIGS. 12 and 13, reference can essentially be made to the statements relating to the above figures. The

Connecting element is preferably made of plastic, in particular of an elastic, preferably soft plastic. The special feature of the present embodiment is that the lips 4.1 of the two ends of the seal are also connected to each other. This can be done by a material connection and / or via a connection by means of

Connecting element 7.
