Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for producing a plastically deformable bonbon mass strand from which a strand is conveyed at a constant speed and unit pieces are cut from the strand by a cutter. The present invention relates to a device for cutting unit pieces.

BACKGROUND OF THE INVENTION Devices are already known for cutting unit pieces from mass strands of soft plastics, which mass strands are conveyed continuously and the unit parts are cut therefrom by means of a rotary cutter.

The cutter has two segments that perform cutting and also serve conveying purposes. The void between these segments of the cutter allows the mass strand to be fed until the cut is made.

Such a method is described in Patent Application No. 3216 of the Federal Republic of Germany.
It is described in Publication No. 770. In this case,
Due to the stationary rotary cutter, a disadvantage is that nearly vertical and clean cut surfaces can only be obtained at low transport speeds of the mass strand. For this, a short ll
The range of use of such a machine is extremely limited, as it can only cut pieces of j length (length).

Another device of this type is described in German Democratic Republic Patent No. 2 ('16).
It is described in Publication No. 067. In this method, stripping drums are supported on both sides of the mass strand in the area of the cutting point, each of which is driven in the transport direction of the mass strand during the cutting process, and these stripping drums are formed with one side open. , the outer circumferential surface of which contacts the mass strand and has at least one slit-like transversely extending opening for a cutter provided at the free end of the connector. The cutter moves back through the opening of the stripping drum and the moving mass strand until it stops in the middle and slightly overlaps. This method suffers from the disadvantage that there is a speed difference between the coupled conveying movement of the strand and the incoming cutter. The speed difference pulls and crushes the unit pieces to be cut, which makes it impossible to obtain a flat cut surface and an accurate geometric shape of the cut unit pieces, which leads to folding. This has a disadvantageous effect on continuous work processes such as lap winding and bar wrapping.

A device for cutting toffee from a toffee strand and forcing it into a packaging machine is known and is described in German Democratic Republic Patent No. 99335. In this method, the cutter cuts the toffee strand in the vertical direction, which is located in the area of the cutting device.

This device has the disadvantage that the transport of the toffee strand is interrupted during the cutting process, and therefore only a limited output can be obtained.

(Problems to be Solved by the Invention) The objects of the present invention are to improve the quality of the cut surface, to obtain an accurate geometric shape of the cut piece at position 111,
The aim is to widen the size range and to significantly reduce the output of such machines.

The object of the invention is to cut a medium section from a constantly fed mass strand perpendicular to the conveying direction without any damming at the cutting point.

(Means for Solving the Problems) According to the present invention, a grooved cam is fixedly arranged on a shaft which is inclined with respect to the strand conveying gutter and fixed to the casing, and this grooved cam is fixed to the shaft. A cutter is attached to at least one cutter holder, which is surrounded by a cutter holding disc rotatably supported by the cutter holding disc and is swingably supported on the outer periphery of the cutter holding disc. This is achieved in that the cutter holder is fitted with a lever having a cam roller that cooperates with the cam track of the grooved cam. The cutter blade is arc-shaped and there is a spacing between the strand conveying trough and the vertical centerline of the cutter holding disc.

(Embodiments) The present invention will be described in detail below with reference to embodiments shown in the drawings.

The device essentially consists of a stationary strand transport trough 1 to which strand transport wheels 2, 3 are attached.

On the lower side of this strand conveying gutter 1, inside the casing 4,
A shaft 5, which is arranged obliquely with respect to the strand conveying gutter 1, is fixed.

A grooved cam 7 is fixedly mounted on this shaft 5 inside a cutter-holding disk 6, the cutter-holding disk 6 being rotatably supported on the shaft 5. A cutter holder 8 is swingably supported on the outer periphery of the cutter holder disk 6. A cutter 9 is fixed to a cutter holder 8 on the outside of the cutter holding disk 6, and a lever 10 with a cam roller 11 that acts in cooperation with the cam track of the grooved cam 7 is fixed inside the cutter holding disk 6. ing.

A drive element 12 of the cutter holding disk 6 is connected inside the casing 4 .

This device works as follows.

Strands S coming successively from a strand forming device (not shown) in a strand conveying trough 1 are conveyed by strand conveying wheels 2, 3 into the area of the cutting device. During the conveying movement, the strand S is cut into medium pieces by means of a rotary cutter holding disk 6, on the outer periphery of which a cutter holder 8 with a cutter 9 is fixed. The shaft 5 and thus the cutter holding disk 6 rotatably supported thereon are tilted with respect to the strand transport trough 1 and with respect to the oscillating movement of the cutter 9 in the strand transport direction carried out during the cutting process. By this arrangement, a lever 10 fixed to the cutter holder 8 acts in cooperation with a cam roller 11 that engages with the cam track of the fixed grooved cam 7 to move the unit piece E from the mass strand in the conveying direction. The cut surface is of high quality. The length of the cut unit piece E can be adjusted within a certain size range by changing the conveyance speed of the mass strand S or by changing the circumferential speed of the cutter holding disk 6.

〔Effect of the invention〕

According to the invention, precise geometric shapes of the cut unit pieces are obtained with high cutting surface quality, and the output of such machines can be significantly increased over a wide dimensional range.
