Description

Device for cutting open, in particular canned food The invention relates to a device for slicing, in particular of cans, in which on a support plate hanging with a U-shaped head on the edge of the liner, by rolling a pulling wheel on the lower side of the can rim along the same is guided, a knife can be brought into the cutting position by pivoting, which cuts out the can cover with the movement of the support plate.

The invention is that the knife within the range of the liner edge rotatable on the inner leg of the U-profile head of the support shield is stored and its back in a slot in the crosspiece of the U-profile head is guided in such a way that the back of the knife at the front in the cutting direction. lying Edge of the slit in the cutting position of the knife AnschJag.

This has the advantage over the known devices, that the device can be made in the smallest dimensions and special, Support elements holding the knife in the cutting position can be dispensed with.

The invention can also be used with a corresponding design of the knife and the lid of the tin can. An automatic pivoting of the knife into the intersection too. In the drawings are embodiments of the device shown according to the invention, which is pointed out in more detail in the description will.

The support plate i is assumed to be known, in which the means Handle z rotatable pull wheel 3 is mounted, which is when working on the underside of the rim of the liner q. rolls off and thereby the carrying shield along the edge of the liner emotional. The carrying shield has a well-known U-profile head that sits on the edge of the can is attached.

According to the invention, the pivotable knife 6 is on the inner leg 5 of the U-profile head of the support shield i rotatably mounted, the angled to an Arm 7 formed knife back a slot 8 in the transverse web 9 of the U-profile head interspersed.

Fig. 1, z and 3 show in plan, in the interior and in the vertical Cut the device in the rest position attached to the edge of the can, while Figs. 4 and 5 in. Interior view and in vertical section the device in show the state in which by pivoting the knife this, against the Supports can cover and lifted the pulling wheel to engage against the edge of the can became.

If now, starting from this position, the handle z is turned further (Fig. 6), the knife tilts while piercing at the same time in the can lid until the back of the knife is at the front narrow edge of the slot 8 is applied, so that with continued rotation of the handle 2, the cover is cut out will.

As can be seen from the drawing, the mounting of the pivot pin can of the knife in the part 5 also a limited tilting of the knife in one plane perpendicular to the cutting direction in order to achieve the cutting position of the To enable the knife. For this purpose, the arm 7 of the knife is equipped with a wedge-like, Approach i o provided,. by hitting the edge of the slot facing it 8 causes the knife to tilt in the aforementioned manner, which also is made possible by a corresponding widening i i of the slot 8.

In the embodiment shown in Fig. I to 7 is the Bearing bolts attached to the knife are mounted in a transverse slot in the shield part 5. According to Fig. 8, however, the bearing bolts 12 of the knife are fastened in the shield part s and the knife is provided with a corresponding transverse slot.

In the embodiment according to Fig.9 and io, the one attached to the knife is located Bearing pin 13 in: an open edge recess 1q. of the shield part 5, which for has already been bent into the desired position of the angular position of the knife, so that the slot 8 is made only in the width of the. Knife back.

An expedient embodiment of the device is shown schematically in Fig. -Ii. The bearing pin 15 of the knife 16 is arranged here so that it lies behind the center of gravity of the knife in the cutting direction. As a result, the latter tends to protrude forward with its cutting edge in the cutting direction and so hit against a pressed-out boss 17 of the can cover. Upon rotation of the handle 2 of passing should therefore, according to the train wheel 3 continues to rotate on the sleeve edge, the knife about the bolt 1 5, pure cut into the liner lid and -at movement of the support plate cut out the box lid in this position.
