Zigzag cutter for sugar confectionery. Patented in the German Empire on April 1, 1923.

The invention relates to a. Device for cutting sheets of sugar confectionery, ζ. B. caramel, in square, rhombic or other shaped pieces.

One has such plates either with the help of a system of two sets of parallel Knives that crossed each other at a right or other angle, cut or first cut the plate into strips by successive cuts.

th by means of a rotating drum with individual knives in a certain arrangement was occupied, and then rotated the table carrying the plate so that the strips were cut again at right angles or diagonally into individual pieces.

According to the invention, a knife which is zigzag in plan is used, wherein the knife plate runs in a zigzag so that each knife blade is zigzag-shaped Cutting line across the plate, in which two adjacent straight stretches of the cut form two edges for each piece to be separated. Will be expedient ! 5 this zigzag knife made from a set of separate, straight, short knives, which are lined up with their ends at an angle to each other, so that they are in their Together form a knife in the shape of a zigzag.

With such a knife after every cut in relation to the plate or the Plate in retraction on the knife by a certain amount alternately in this or the is shifted in another direction, the next cut causes pieces the shape you want can be cut out after of course after each Cut the plate has also been moved forward by the required amount.

The knife does not necessarily have to be arranged in such a way that its longitudinal direction is at right angles to the direction of advance of the plate and can be moved back and forth to the side must, but the knife can also be askew above the plate, so that the direction of advance the plate is convergent every other straight line segment of the knife. Then there is a sideways shift of the deep knife unnecessary after each cut.

Embodiments of the invention are illustrated in the drawing.

Fig. Ι is a vertical cross-section through an embodiment of the i Schneideinrich-: tion, in which the plate with respect to the j or the knives wiird moved. Fig. 2 is a side view thereof, Fig. 3 is a plan view.

Fig. 4 is part of an end view of another embodiment of the device, in which the knife or knives are moved with respect to the plate.

Fig. 5, 6 and 7 are individual representations of the knife arrangements in the diagram in horizontal cut or in a vertical cut.

In the machine shown in FIGS. 1, 2 and 3, a table b is arranged so as to be longitudinally displaceable between the two side frames α and is communicated with a step-by-step movement ^{by means of an endless chain for 1.}

The table is with. connected to the chain by a chain tensioning device b ' ^2. The chain runs over sprockets c, which are fixed on shafts i ' ¹ l). On one shaft c * , ratchet wheels c ² are also attached, with which ratchets c ³ interact. The pawl on one side is used to move the chain and thus also the table in one direction, the pawl on the other side of the corresponding movement in the opposite direction. Depending on the movement required, one or the other pawl is inserted into the associated ratchet wheel. Each of the ratchet wheels is provided with an toothless circumferential section c ⁴ , which the forward movement of the table in the one l> ezw. the other direction is limited. The pawls c ³ are moved by means of rods c ' , which in turn are driven by eccentrics c ″ on the main drive shaft. This drive shaft also moves the knives up and down by means of those eccentrics and the lateral tie rods d ² an Ouerstück d "' 1> which slides in approaches o ^{1 of} the side frame. This crosspiece also carries a stripping plate tf ⁴ , which is subject to the action of a deflector, as is customary in such machines.

The plate to be cut lies on a board on the table of the machine between side rails e, which are alternately moved laterally in opposite directions, since those side ^{rails are supported by angle helmets c 1} , which are at e ² . the side frames are mounted and brought to uniform movement by means of coupling rods e '. A lever f serves to bring about the movement of the rails, which on the one hand engages the elongated pin of one of the angular heels c ¹ and has its support point at f ¹ , but on the other hand is influenced by a thrust curve / ² in the drum / ^:> a shaft f * , which is rotated from the main drive shaft d by means of the spur gears / ⁵ , / ". A hand lever g is used to put the machine in and out of operation with the aid of the clutch g ^1. This shows that while the table is moving forward no is moved, the plate to be cut gradually receives a series of zigzag cuts from the knife group .1-, and that between every two cuts with the knife raised the plate a lateral movement in one direction or the other - is given of such a size that it for a further cut so that two edges of squares or rhombuses have been cut out of the material each time, when the table has reached the end of its stroke and the plate is finished cut, so the other one hears

Forward movement of the table because of the toothless surface of the effective Ratchet wheel on. Now the plate is removed and replaced by another plate; seats carrying a fresh blackboard. Then I becomes the direction of movement of the table through this! conversely, that the one that has just been effective! Pawl disengaged and the other j Ratchet is inserted into your ratchet. J

ίο In Fig. 4 the essential parts of a machine according to the invention are shown, in which the knives perform a string movement with respect to the panel to be cut. The reciprocating movement of the table in the longitudinal direction and the up and down movement of the knives can be effected by the same or similar means as described above; however, rails e movable to and fro laterally are not necessary.

On the other hand, the knives χ are attached to a beam h which can be moved in the transverse direction of the machine by being slidably mounted in dovetail guides on the crosspiece e " . The lateral movement of this beam to one side and then to the other side winds this through a group of levers 'granted by a central lever Ii ^1, the shaft of h ² in jerky movement offset is. that lever h ¹ is by means of rods ^s h with the angle levers h ⁴ coupled by. one each located on each side of the machine. This angle lever are coupled by means of push rods h ^s with levers h ″ , the inwardly protruding ends of which alternately ^{grip under an edge or a shoulder / t 7 of} the beam h and are designed in such a way that they produce a locking effect that shifts the beam and the knife laterally. This effect occurs alternately on one or the other side when the knives are moved upwards.

The construction of the knife is illustrated in Figs. 5 to 7. Each individual knife i is bent at a right or otherwise desired 4-5 angle, so that it has two cutting edges at that angle to one another. Screws i ¹ and spacers i *, which press the knives against the support bar i " , which expediently protrudes over the knife back ^{to form a support shoulder for the knives at i 3} 'and the connecting parts of the cutting edges, serve to fasten the individual knife" to relieve occurring forces.

At the joints i ⁿ , the knives are ground so that they lie tightly against one another and are sharpened on their inside at i " .

Claims (4)

Patent Claims: 1. Zigzag cutter for sugar confectionery, characterized by a knife group with a zigzag-shaped cutting edge and a device for moving the Knife to the cutting plate in such a way that the successive Cuts join one another in such a way that pieces of the desired one between them Shape to be cut out. 2. Machine according to claim r, characterized in that after each cut a displacement of knife and plate to each other alternately to one or the other side in the longitudinal direction of the knife takes place. 3. Machine according to claim 1, characterized in that the individual knives with two cutting edges abutting each other at an angle (i) are fastened in a holder (i ² , i ⁴ ) in such a way that they together form a zigzag cutting edge. 4. Machine according to claim 1, characterized in that the knife holder (P) opposes the knife back with a stop shoulder (i ³ ) which relieves the fastening parts of the knife from the cutting pressure.
