Description

The The invention relates to a cutting machine for loaf-shaped products, such as sausages, bacon sides, cheese sticks and the like according to the preamble of claim 1.

such Cutting machines are used in factories, the sausages, bacon sides, cheeses and the like cut and the separated slices or portions put together to sales units. Such sales units can one include single serving, z. B. a piece of hard cheese; You can also use a disk stack contained, which consists of a plurality of product slices. such Disk stacks can also be generated shingled.

Known market Cutting machines have cutting heads on which have spiral or eccentric blades, with a drive shaft rotate (orbital knife) while slicing the product loaf. Unless it is relatively thin and flexible product slices, produces the spiral knife when Cutting a smooth surface. When cutting massive portions, however, significant wedging forces occur, so that the rotating spiral knife on the cut surfaces unwanted scoring leaves.

task The present invention is a cutting machine according to the preamble of claim 1 so that they are easy for cutting from product slices to slices or in massive portions optimized can be.

These The object is achieved by a cutting machine having the features specified in claim 1.

According to the invention is on the cutting machine provided a cutting head frame, which makes it possible convert the cutting head quickly and easily for the required cutting function, by only the cutting units must be replaced. The Cutting units are optimized for the respective cutting function. Thus, a cutting unit may be provided, which the product loaf slices quickly, and another cutting unit can especially suitable for cutting massive portions.

advantageous Further developments of the invention are specified in the subclaims.

at an advantageous embodiment according to claim 2 may include one of the cutting units for cutting slices Imlaufmesser have, with the product loaf particularly fast and evenly sliced can be cut. The orbital can be easily turned on Drive shaft of the drive motor are mounted.

Further can according to claim 3 one of the cutting units for cutting portions of a linear knife having, with an eccentric drive for cutting the Produktlaibs is linear to the product loaf and to move away from it. A linear meter is particularly suitable for the smooth cutting of massive Product slices, with significant wedge forces occur. The eccentric drive allows easy the conversion of a rotary motion into a linear motion for the line armesser, making the cutting unit easy with that too for the spiral knife usable drive shaft of the drive motor connected and driven can be.

Especially advantageous may according to claim 4 the cutting unit for cutting portions one with the cutting head solvable fixed to the housing connectable guide unit include. A knife carrier, who wears the linear meter, can with the leadership unit linearly guided be. An eccentric drive is particularly easy with a circular disk feasible coaxially on the drive shaft of the drive motor is attachable and a drive rod, with one end articulated eccentric on the disc and hinged at the other end on the knife carrier is stored, such that when rotating the circular disk, the drive rod the knife carrier with the linear knife linearly on the product loaf and to this away emotional. With each movement on the Produktlaib to a portion the Produktlaibes cut between the cuts further cut off become.

Around to get a uniform cut surface, can according to claim 5 the linear knife plate-shaped be. In this way, also the required dimensional stability achieved to bend the linear blade when strong wedging forces occur and correspondingly uneven cut surfaces too avoid. Viewed from the cutting edge behind the cutting edge the linear knife a plurality of straight, continuous slots have, parallel to the direction of movement of the linear blade run. In this way, the area of the knife at which the Product loaf or the portions are applied and so is the friction of the linear blade on the product loaf or on the portions reduced. Furthermore, it reduces the risk that parts of the Products stick to the linear knife, causing unsightly breaks on the cut surfaces can arise.

According to claim 6, different work programs of the control unit are automatically set for the cutting machine, depending on which of the various cutting units is currently coupled. Thus, a work program can be optimized specifically for the cutting of portions, the product loaf is pushed with the feed device after each cut to a distance corresponding to the portion on the cutting head and before the cut the feed is stopped. Another program of work may be optimized for cutting slices, with the product slab constantly being pushed onto the cutting head.

The cutting machine described above works in the way "cut portions" as follows:
After cutting off a portion of the Produktlaib 15 (or the set of juxtaposed product loaves) by a distance corresponding to the portion size to the cutting head 14 delivered.

Possibly. is then with the control unit 40 the positioning jaw motor 68 controlled so that the positioning jaws 64 and 66 be pushed towards each other and the product loaf (set) is positioned transversely, if necessary, also clamped.

The drive motor 61 then drives caused by the control unit 40 over the transmission 59 and the drive shaft 55 the circular disk 110 at. This lowers over the drive rod 108 the knife carrier 92 with the linear meter 18 , The latter separates when lowering in cooperation with the counter knife 60 a portion of the product loaf (set) 15 from. The portion falls on the first belt conveyor 42 , goes to the second belt conveyor 44 handed over and transported by this to the packing station.

Then, if necessary, the positioning jaws 64 and 66 open.

Then, by further rotation of the circular disk 110 the linear meter 18 raised, and the feed device 20 via the control unit 40 triggered such that the product loaf again to the predetermined, a portion corresponding distance to the cutting head 14 is moved. Then the next portion is separated in the manner described above, etc.

In the "slicing" mode, the cutting machine described above operates as follows:
With continuously rotating spiral knife 16 the product loaf is delivered continuously. The on the belt conveyor 42 falling discs 17 make up a pile there. Does this include a given number of discs (the control unit 40 counts the revolutions of the drive shaft 57 ), the entire stack is quickly started by the belt conveyor 42 and the downstream of the belt conveyor carried away quickly, wherein by the control unit 40 if necessary, the delivery of the Produktlaibes 15 for one turn of the spiral knife 16 is suspended.

The conversion of the cutting machine from the work type "cut slices" to the working mode "cut portions" is done as follows:
The spiral knife 16 is from the open front of the cutting head frame 44 from the drive shaft 55 unscrewed and removed.

Subsequently, the linear knife unit 74 from the open front of the cutterhead frame 44 out with the base plate 76 introduced in advance. This will be the feet 90 the sliding bars 84 from below into the counter knife 60 hooked.

The spacers 80 be on the back wall 48 of the cutting head frame 44 screwed and so the base plate 76 on the cutting head frame 44 fixed.

The circular disk 110 is on the drive shaft 55 of the drive motor 61 screwed. For this purpose, the circular disk 110 turned into a position in which the knife carrier 92 is in its lower position and so is the circular disk 110 from the open side of the cutterhead frame 44 is accessible from.

Furthermore, the two mounting cylinders 88 on the upper ends of the slide bars 84 with the top wall of the cutterhead frame 44 screwed.

Replacing the linear blade unit 74 against the spiral knife 16 to change the cutting machine of the operation "cut portions" on the operation "slicing" is done in reverse order.
