Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention consists of a central rotary distribution disk with ring parts rotating in the same direction and containing discs distributed equidistantly around the circumference of the ring part. The present invention relates to a device for dispensing small-sized products, especially bonbons, which are provided with pockets.

[Conventional technology]

Many feeding devices for bonbon packaging machines are already known which are constructed on the basis of rotary distribution discs.

These dispensing devices differ in their detailed construction aimed at increasing the dispensing capacity. UK patent no.
The system known from 829758 can only be operated intermittently. The bonbons are then placed into the pockets of the dispensing table by centrifugal force and, once stopped at the transfer point, are transferred together with the packaging material into the open holding element of the wrapping ring by means of a ram passing vertically through the pockets. handed over to.

This feeding device has the disadvantage that the production output is severely limited due to its intermittent operation.

DE 125 742 describes a distribution device consisting of a central rotating distribution disk, an intermediate ring rotating in the same direction, and an outer ring rotating in the same direction. The distribution disk is of conically raised design. The intermediate ring has a larger diameter than the distribution disk and supports a plurality of radial segments. These radial segments taper inward,
It has an entrance for Bonbon. These segments form grooves parallel to the width of the bonbon to be accommodated. Receiving pockets are arranged in the outer ring such that one receiving pocket coincides with a groove in the intermediate ring at a predetermined location of the circumference for each rotation of the outer ring. A disadvantage of this device is that the bongs stick to the grooves of the intermediate ring, which results in insufficient filling of the receiving pocket.

[Problem to be solved by the invention]

The object of the invention is to significantly increase the filling rate of the receiving pockets of the feeding device, thereby making it possible to receive a bonbon in each holding element of the gripping ring, and to increase the output of the packaging machine. .

The object of the invention is to place unaligned bonbons in a machine position in order to enable an unhindered transfer process with the holding elements of the gripping wheels.

[Means to solve the problem]

According to the invention, this object is achieved in that the upper ring part has on its inner periphery an edge which is interrupted by a plurality of inlet channels and has side walls of the same height extending radially outwards. , adjoining each of the introduction channels, this is achieved in that the side walls protrude through openings in the upper ring and are supported in a lowerable manner in pairs at the delivery position of the bonbons.

[Effect]

This makes it possible to significantly increase the filling rate of the feeder, in which case a blockage of the bonbons at the edge of the upper ring is prevented by the difference in circumferential speed between the distribution disk and the upper ring. Since the bonbon can only be removed by the holding element from the receiving pocket which has reached the transfer point for the second time,
It allows more time to introduce the bonbons into the storage pockets of the upper ring, so that the time between two rotations of the upper ring is utilized for the bonbon sorting process. By increasing the filling rate of the receiving pockets of the upper ring, the filling rate of the holding elements of the gripping wheels is also increased, so that the output of the packaging machine can be increased.

〔Example〕

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

The feeding device essentially consists of a central rotating distribution disk 1 with an upper ring 2 and a lower ring 2a rotating in the same direction. The upper ring 2 is provided with storage pockets 3 distributed at equal intervals around the circumference. These receiving pockets 3 are formed by the presence of an edge 4 on the inner periphery of the upper ring 2, which is interrupted by an inlet channel 5. These inlet channels 5 are adjoined by side walls 6 of the same height as the edges 4 which extend radially outwards. These side walls 6 project through openings 7 in the upper ring 2 and are each arranged in pairs on a square lever 8. A bias pressure is applied to the rectangular lever 8 by a spring 9. The rectangular lever 8 has at one end a cam roller 10 that rolls on an annular cam track 11. The cam trajectory 11
is fixedly provided within the housing 12.
A distribution disk 1 and an upper ring 2 are arranged in the housing 12 so as to be rotatable independently of one another. The distribution disk 1 is mounted on a vertical shaft 13 and is supported by a ball bearing 14 in a central fixed bearing sleeve 12a, to which the upper ring 2 is mounted concentrically inside the housing 12 in a ball bearing 15. It has been well supported. Lower ring 2a
A bevel gear 16 is fixed to the housing 12 and meshes with a bevel gear 18 on a horizontal drive shaft 18 supported within the housing 12 . A gear 19 is attached to the lower side of the bevel gear 17 on the lower ring 2a. This gear 19 meshes with a gear 20 of a countershaft 21 supported on its side. At the bottom of the secondary shaft 21,
Another gear 22 is mounted which meshes with the gear 23 on the shaft 13. These structural parts are for driving the distribution disk 1 and the ring parts 2, 2a.

In order to selectively lock the square lever 8 at the transfer point of the grip ring 32 to the holding element 24,
Structural components described below are utilized. Fixed cam trajectory 1
1 , a horizontal locking disk 25 whose outer circumferential surface is provided with a radial cam projection is supported concentrically in a ball bearing 26 . Its radial cam projection is dimensioned, depending on its rotational position, in such a way that it abuts the other cam roller 27 in the swung state of the square lever 8. A gear 28 is attached to the locking disc 25 and meshes with a gear 29 of the countershaft 21.

In order to prevent the bonbons from radially exiting the receiving pocket 3, a restriction pin 30 is mounted in each case on the upper ring 2 radially outward and behind the receiving pocket 3. To prevent unsized bongs and debris from getting caught between the two limiting pins 30 as shown in FIG. It can also be formed with an inwardly curved end.
A cover ring 31 is arranged at the height of the protruding side wall 6 to improve the alignment of the bongs and to prevent them from bouncing upwards.

Next, the operation of the device based on the present invention will be explained.

Driving power is introduced via a horizontal drive shaft 18.
Ring parts 2, 2a are driven via bevel gears 17 and 16. The driving force is the lower ring 2a
The signal is transmitted to a gear 20 on a countershaft 21 by a gear 19 provided on the countershaft 21 . The gears 22, 2 are connected by the countershaft 21.
3, a shaft 31 with distribution disk 1 is driven. This causes the distribution disk 1 and the upper ring 2 to rotate at different rotational speeds, so that the bonbons on the distribution disk 1 are forced outwardly in the direction of the receiving pocket 3 by centrifugal force, Fill with high filling rate. At first, the side wall 6 of the storage pocket 3 is such that the rectangular lever 8 moves along the cam roller 10 due to the course of the cam track 11.
so that it is in the extended position as shown on the left side of the drawing. The cam track 11 is recessed at the transfer point U of the holding element 24, so that the side wall 6 descends below the bottom of the introduction channel 5, as shown on the right side of the drawing. This allows the holding element 24 to grip the bong evenly without any hindrance.

This working step is carried out without the locking disc 25 acting on it. The operation of the locking disc 25 will be explained below. The locking discs 25 are used to alternately lock the lowering of the side walls 6 of the storage pocket 3 at the transfer point U in order to increase the filling rate in the storage pocket 3. The locking disc 25 is driven by the countershaft 21 via a gearwheel 29 . This gear 29 meshes with a gear 28 on the locking disc 25. In that case, the circumferential speed of the locking disc 25 is such that the cam roller 27 of the rectangular lever 8 of every other storage pocket 3 at the delivery point U
is designed to contact a cam projection on the locking disc 25. This prevents the side wall 6 from descending. The resulting alternate removal presupposes that an odd number of storage pockets 3 are arranged in the upper ring 2. The advantage of this procedure is that since removal is performed for the first time during the second rotation of the ring parts 2, 2a, more time is available for arranging the bonbons. While the bonbon is arranged in the receiving pocket 3, the cover ring 31 prevents the bonbon from entering that position. In that case, the cover ring 31
2 is interrupted at the transfer point U. The exit of the bong radially outwardly from the receiving pocket 3 is prevented by the restriction pin 30, but debris can pass through.
