Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an apparatus for manufacturing individual shoulder pads from a strip-shaped material, which shoulder pads are folded in a subsequent step and placed in a hinge-shaped cigarette packet. be.

As is well known, the shoulder rest designated by reference numeral 1 is attached to the central panel 2.
and a lateral flap 3 having the same shape.

Between each flap 3 and the central panel 2 there are provided score lines 4 and cut-outs 5 which weaken the paperboard to make it easier to fold.

Such a shoulder pad 1 is manufactured in a cigarette packaging machine for forming rigid packets of cigarettes, and such a shoulder pad 1 is obtained from a continuous thin paperboard strip N.

According to Japanese Patent Application No. 49-146253 filed by the same applicant, a strip of paperboard is cut into individual shoulder pads 1 by moving the paperboard forward along a horizontal feeding path. Sent.

Along this supply path, a device for forming the notches 4 and incisions 5 and a strip drive device are arranged.

Both devices include cutting rollers rotating in opposite directions, working at two separate locations along the feed path, and driven by the same source of intermittent motion via a gear train.

According to the description in said application, in order to accurately form the longitudinal dimensions of the shoulder pad incisions 5 along the folding or folding lines, contact loss or slippage between the drive roller and the paperboard must be minimized. It is necessary to carefully reduce and avoid even the slightest play between the multiple gears of the gear chest.

The device according to said patent application therefore comprises a device for manually adjusting the pressure of the drive roller on the strip, and a known device arranged to provide constant meshing between the gears of the gear train.

Although these methods of correction are extremely effective in terms of the results obtained, when manual adjustments are made, they use a large number of gears, resulting in expensive equipment and lack of practicality and accuracy. There are many drawbacks that can be attributed to this.

OBJECTS OF THE INVENTION It is an object of the invention to provide a device in which the pressure of the drive roller on the paperboard of the strip can be automatically adjusted.

Another object of the invention is to provide a device which eliminates or reduces many of the disadvantages resulting from the use of multiple gears.

Another object of the invention is to provide a device which is smaller in construction, simpler and more economical than the known devices mentioned above.

The purpose of the above is to provide a device for manufacturing individual shoulder pads from a strip of material which are folded and placed in hinge-lid cigarette packets in the next step, the device being connected to a cigarette packaging machine. , a roller device in combination with a first back roller device for intermittently feeding the strip; the roller device in combination with a second back roller device offset-cuts the strip into the strip; The strip is fed on a path extending between two scoring/cutting roller devices that make two rows of notches parallel to the direction, and is further disposed near the path downstream of the roller device to cut the strip. In an apparatus for manufacturing individual shoulder pads, which is equipped with a cutting device for cutting in the transverse direction to obtain shoulder pads of the same shape, a roller device that intermittently feeds the strip and a first back roller device are connected to a second back roller device, respectively. coaxial with a back-roller device and a scoring and cutting roller device, and wherein said roller device or first back-roller device has a resilient flexible material between a metal shaft and a corresponding metal outer ring; This is achieved by means of an apparatus for producing individual shoulder pads from a strip of material, characterized in that it has an inner ring of.

(Example) A detailed description of the invention is provided with reference to the accompanying drawings.

1 and 2, reference numeral 6 designates the casing of the device according to the invention, which casing is attached by means not shown to a machine for forming rigid hinge-lid cigarette packets. .

A horizontal shaft 8 provided on the side wall of the casing 6 via the eccentric bushing 1 is intermittently rotated counterclockwise by means not shown.

Two identical gears 9, 9' are arranged next to each other on the outside of the casing 6 and are fixed to the left end of the shaft 8, the gears 9, 9' being arranged parallel to and below the shaft 8. The gear 10 that drives the shaft 11 is rotated.

On the shaft 11 inside the casing 6 there are two discs 12 and 13, each disc being located close to two opposite inner walls of the casing.

Two integral back rollers 14 and 15 are connected to the disk 12.
and 13.

The shaft 8 is also provided with two further back rollers 16 and 11, which contact the disks 12 and 13, respectively.

The shaft 8 is also provided with two integral rollers 18 and 19, which abut the rollers 14 and 15, respectively.

An important feature of the invention is that the inner rings 20 of the two rollers 18, 19 are made of rubber or other elastic material, and the outer rings 21 are made of metal.

Conversely, the back roller may be formed of an inner ring of resilient material and an outer ring of metal.

In either case, the outer surface of the metal outer ring is provided with a number of parallel grooves that function as an annular band for dragging the strip.

The metal dragging band is connected to the shaft 8 or 11 via the respective elastic inner ring.

A continuous paperboard strip N is unwound from a coil (not shown) and is fed along a horizontal plane by two sets of rollers 14, 18 and 15, 19 acting at the center of the paperboard strip.

The two discs 12 and 13 have respective rollers 16 and 11.
It has a cutter part having two series of parallel and longitudinal notches cut out over its entire periphery in cooperation with the cutter part, and cutouts 5 are provided at regular intervals between the notches 4 of each series. ing.

The strip N is then fed to a cutting device described in the aforementioned patent, but not shown, and cut into individual shoulder pads.

In order to completely cut the shoulder pad material 1, use the back roller 1.
A length that brings 6 and 11 into close contact with the edge of the cutter on the outer periphery of the respective disc 12,13 is sufficient.

This action can be easily carried out by setting the device by rotating the eccentric bushings to assume their respective positions.

A bundle 20 fixed to the bushing 1 is provided for this purpose.

A long hole is formed in the bundle 22, and a bolt can be passed through the long hole and fixed to the side wall of the casing 6.

The presence of an inner ring 20 of elastic material as part of the rollers 18 and 19 makes it possible to maintain an even, slip-free contact between the feed device and the paperboard strip N during the entire operating time of the device. .

Finally, the gears 9 and 9' have through holes, and the gears 9, 9'
It is designed to eliminate any possible play between ' and 10' by a slight relative rotation between the gears.
