Description

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for arranging low (flat) cylindrical tin cans in a filled, sealed state and for dispensing into continuous canning industry, particularly sterilizing machines. A tin can is considered a small (flat) cylindrical box if the ratio of its height to its diameter is equal to or less than 0.5.

Canned food for small consumers is often packed in flat boxes, especially for packaging food items weighing 1/10, 1/5, 1/2 kg.

Until now, there is no known device for sorting flat boxes. It is known, however, to dispense flat tin cans, in which the cans are arranged in series on their circular motherboard, and in this position are dispensed at one or more levels, e.g. permeable cups, but suitable equipment for arranging flat boxes on their mantle and dispensing them into the canning industry, especially for sterilization, is unknown.

Many solutions are known for dispensing cylindrical sealed cans (tins) into the goblets of sterilizing machines having a height to diameter ratio greater than 0.6.

Such tin can dispensing equipment is described on page 222 in the Canned Food Pocket Book (Agricultural Publisher, Budapest, 1972) for a drum paste machine, in which the dispenser has a taxiway and a helical guide. On p. 233 and p. 234, the pocket book describes the dispensing and dispensing structure of the hydrostatic tower steriliser, in which the boxes arrive on a taxiway or footbed and leave the steriliser after heat treatment.

In the dispenser of the hydrostatic sterilization machine, which is the subject of Hungarian Patent Nos. 149,964, 151,610 and 158,292, high canisters (canisters) are delivered on conveyor soles, lay down one at a time, the bottles (boxes) close tightly to their axis before the goblet, and the dispenser puts the goggles (boxes) on the two sides of the sterilizer on two sides.

In the case of the loading and dispensing apparatus of Hungarian Patent No. 170,128, the cups have to be approached from two sides, so these dispensing devices are large and labor-intensive.

The metering device described in Hungarian Patent Application No. 179 084 is provided with feed tapes, a metering star, elements for positioning the cans (boxes) in their axial direction, and means for lifting the cans (boxes) to the orifices leading to the cup opening. it has bottoms (boxes) from the opening of the cup, conveyor belts attached thereto, and foot conveyors conveying them perpendicularly to the bottles (boxes).

Also known are Stork, made in the Netherlands, Amelioair in France, and Mitchell in England, which have inlet and outlet structures similar to those for hydrostatic tower sterilizers.

A common feature of all known box organizing and dispensing devices is that they arrange the boxes ('brain bottles') on their mantle as long cylindrical cylinders in the direction of transport, so that they are rolled into a box transport container capable of accommodating 1-2 rows or more. . The disadvantage of all these solutions is that they can only be used with boxes having a height to diameter ratio greater than 0.5, i.e. the box height is equal to or greater than half the diameter. Such cans are stable only when they are on their mantle. None of the prior art devices are capable of sorting and dispensing boxes having a height / diameter ratio of less than 0.5. Such flat boxes are not sufficiently stable when lying on their mantle and therefore cause malfunctions when tilted during handling.

British Patent No. 1,173,333 discloses an in-and-out dispensing structure for a pressurized hydrostatic sterilizing device, wherein the in-and-out dispensing is effected by a rotary sluice solution for overpressure of the sterilizing device and a conveyor suspended on the carrier chains. it consists of a rotatable outer cylindrical drum which is open along its creator and a coaxial inner rotatable drum, also rotatably mounted on its periphery. The pressure on this unit is low ^! The metering rotary-sluice solution requires expensive and complicated construction, but also the structure of the conveyor because the conveyor operation requires that both the upper F and the inner cylinders are properly rotated relative to each other for their intended purpose.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an airely capable unit for high-throughput sorting of flat cylindrical boxes or bottles (further in boxes) and for feeding a long lying cylinder formed from sheet boxes into the goblets of a continuous operation sterilizer used in the canning industry.

The invention is based on the discovery that flat cylindrical tin cans (height / diameter ratio equal to or less than 0.5) can advantageously be fed into the styrofoam cup over the entire width of the cup by inserting flat boxes into the dispenser through circular baseplate holes. first, by cascading through sliding rails, channeling them into the channels of roller coaster rails - box-widths, and then coaxially rolling the boxes into a sort of length, corresponding to the same number of boxes - it is also exposed - push it into the goblet with the help of a lifting box and a feeding table.

The device according to the invention for sorting and dispensing the low, cylindrical, sealed tin cans into the goblets of a continuous sterilization machine is made of a box delivery device, sensors and cylinders, preferably an electropneumatic control system, preferably in the same plane as the sliding plate having a cascade connecting to roller coaster rails, each having a stepped slope, having a slope prior to joining and having sliding rails separated from each other, having a width greater than the height of the boxes; from a box organizer with a parallel rail receiving section and a dispensing section, comprises a feeding table attached to the section and has a sliding bar on the side of the conveyor belt further from the slides, a stop bar at the end of the thrusting runway, an inserting means from the receiving section to a feeding section, a loading device from the feeding table .

The drawings schematically illustrate an exemplary embodiment of the apparatus of the invention.

Figure 1 is a plan view of the apparatus according to the invention,

Fig. 2 is a vertical sectional view of a flat box received in a circular baseplate received by the apparatus on a roller coaster,

Figure 3 is a side view, partly in section, of a box rolling from a roller coaster to a box organizer bar;

Figure 4 is a partial sectional view of inserting the box from the box organizer into the cup.

Fig. 1 shows a top view of the apparatus according to the invention having, as in the example, a conveyor belt 1 for supplying the flat boxes 14 and a sliding plate 4 attached thereto, the latter of which fits snugly with the conveyor belt 1 parallel - to the forced rollers 7 so that each of the 5 steps fits into the different forced rollers 7. Figure 1 further illustrates that the downwardly sloping roller conveyor tracks 7 terminate at the bottom of the box organizer 17, from which the dispensing section 17b passes the boxes 14 forming the coaxially closed box series through the dispensing table 26 into the box 21 of the hydrostatic sterilizer.

The boxes 14 are moved by known electro-pneumatic control systems via sensors 2, 3, 20 and cylinders 11, 18, 2, 28,

To detect the arrival of the first box 14 at the end of the horizontal or downward conveyor belt 1, the sensor 2, the sensor 3 to transfer the entire box row from the conveyor belt 1 to the slide plate 4, to slide the conveyor belt 1 The slider 10 is actuated by a cylinder 11 on its side. The new boxes 14 arriving after the alignment of the conveyor boxes 14 between the sensors 2 and 3, at the width of the shuttle 10, are stopped by a stop member 10a perpendicular to the shuttle 10 on the side of the shuttle 10.

The slider 10 is moved by the cylinder 11 to indicate the sensors 2, 3 parallel to the plane of the sliding plate 4. The lower portion 13 of the sliding bar 10 deflected between the sensors 2, 3 can be tilted about the rotation axis 12, but not in the opposite direction, because this is prevented by the stop 13a attached to the sliding strip 10 (Fig. 2). The lower edge 13 of the lower part 13 of the sliding strip 10 is higher than the upper color of the rails 32 separating the sliding tracks 4a.

In the same plane as the transport plane of the conveyor belt 1, i.e. horizontally or downwardly in the direction of travel of the conveyor belt 1, the sliding plate 4 arranged by slides 4a separated from each other by the rails 32 is fitted to the conveyor belt.

The slideways 4a are preferably wider than the diameter of the flat boxes 14 so that the boxes 14 may just slip within the limits 32. The slides 4a, as seen from the top view in FIG. 1, are stepwise connected to a forced roller 7 so that the stairs 5 of the first slope 4a are furthest from the conveyor l and the last (lowest) stairs 5a of the slider 4a fits to a roller coaster.

Figure 2 illustrates that the slides 4a are connected by a slope 6 to the corresponding roller coaster 7, which is deeper than the radius of the box 14, consisting of vertical dividers 8 separating the paths and a bottom plate 9 inclined towards the box organizer 17. The width of the forced rollers 7 is only greater than the height of the box 14 so that the boxes 14 can slip unhindered from the slope 6 into the forced rollers 7. The alignment of the slides 4a with the corresponding thrusting tracks 7 is as shown in Fig. 2 so that the slides 14a slid on their circular baseplate 4a on the periphery of the thrusting tracks 7a.

If the conveyor belt 1 is inclined, it is preferable that the inclination angle 9 'of the sliding plate 9' of the pressing tracks 7 parallel to each other and preferably to the conveyor belt is preferably the same as the incline of the slab 5 It falls.

The number of thrust tracks 7 is equal to the number of boxes 14 which can be pushed by the sliding bar 10.

On the sloping thrusting tracks 7, the boxes 14 which roll down on their mantle collide with the impact bar 16 at the end (bottom) of the thrusting tracks 7, extending across the full width of the thrusting tracks 7 and movable in a vertical plane with the cylinder 15. The stop 16 of the cylinder 15, which is moved vertically, prevents the boxes 14 from rolling away from the thrust tracks 7 in their lower position. At the lower end of the roller conveyor tracks 7, the box organizer 17, which is provided with two parallel rails 17c, is preferably perpendicular to the force tracks. The boxes 14 are rolled onto the two parallel rails 17c when the rails 16 are lowered (Fig. 3).

The box organizer 17 is comprised of two interconnected sections, a long receiving section 17a at the end of the thrusting tracks 7 and a feed section 17b forming a continuation therewith.

In the box organizer 17, the boxes 14 located on the two parallel rails 17c can be moved from the receiving section 17a by the pusher 19 driven by the cylinder 18 to the feeding section 17b and locked up to the sensor 20 therein. The insertion member 19 is movable parallel to the rails 17c to the extent of the width of the thrust tracks 7. The cylinder 18 is movably supported on the stop 35 by the force exerted by the spring 33 (or weight) on the horizontal straight track. Depending on the position of the thrust member 19, the cylinder 18 may be displaced backwardly by the pneumatic internal force against the force exerted by the spring 33 (or weight). When this internal force is removed, the cylinder 18 moves forward and bumps against the stop.

In the feed section 17b of the box organizer 17, the closure of the boxes 14 over the entire width of the section is indicated by a sensor 20 at the end of the feed section 17b.

In parallel to the feed section 17b, the feeder 23 actuated by the cylinder 22, which is rotatable about the axis of rotation 24, is locked in the feed section 17b and is slightly lower than its level. The boxes 14 are lifted over the insertion bar 25 to a leveling table 26 facing the cup 21 and bordered by side plates 26a on both sides. From there, the insertion bar 25, which is pivotable about the axis of rotation 27 and actuated by the cylinder 28, conveys to the cup 21 (Fig. 4) by inserting a sliding strip 29 supported by a spring (cut) weight rotatable about the axis of rotation 30.

Berendezés The apparatus of the invention operates as follows.

On the conveyor belt 1, which is preferably inclined, the boxes 14 arriving in one or more rows form a closed queue, colliding with each other at the end of the belt and then locked together. The arrival of the first box 14 at the end of the conveyor 1 is indicated by the sensor 2, and the arrival of the last box 14 by the sensor 3. The simultaneous signaling of both sensors 2, 3 indicates that a closed box series of boxes 14 is formed on the conveyor 1. As a result of this marking, the cylinder 11 moves the sliding bar 10 perpendicularly to the row of boxes, thereby moving the boxes 14 on the sliding plate 4 in the slides 4a between the corridors 32 towards the thrusting tracks 7. The new boxes 14 arriving on the conveyor belt 1 collide with the stop element 10a fixed to the end of the slider 10, and as soon as the slats 10 move to the top of the sliding plate 4, the new boxes 14 pass between the slider sections 2 and 3. they create a series of boxes.

The boxes 14 advancing on the slides 4a are inclined on the slope 6, and then fall on the inclined bottom plate 9 between the vertical response plates 8 of the thrusting tracks 7. On the inclined bottom plate 9, the boxes 14 on their mantle roll forward due to gravity and then lined up behind each other in the face of the impact plate 16. It is irrelevant for operation that one or more rows of boxes are simultaneously present on the collision 16. If the slope of the conveyor belt 1 is the same, then at the end of the sliding plate 4, the boxes 14 are placed at the same circumference at each of the steps 5 (at the end of each sliding path 4a).

As soon as each box 14 has fallen into its own compression path of the pond 7, the slide bar 10 returns to its original position to actuate the cylinder 11. During this movement, the lower part 13 of the sliding bar 10, striking the boxes 14, pivots over the boxes 14 and rotates about the axis of rotation 12, and then tumbles freely over the boxes 14, allowing the next row of boxes to be pushed.

Simultaneously with the retraction of the sliding bar 10, the cylinder 15 moves downwardly the stop bar 16, whereupon the recess on the lower end of the thrust stroke 7 rolls onto the parallel rail 17c of the receiving section 17a of the box organizer 17, and then moves upwardly - an upper position of the box 14 to prevent rolling. Arriving at the upper position of the bar 16, the cylinder 18 is actuated which, by means of the insert member 19, completely closes the boxes 14 and pushes the row of boxes forward to the feed section 17b of the box organizer 17.

It is important that the design of the thrusting tracks 7 and the trolley organizer 7 ensure that the unstable boxes 14 on their rolling mantle are supported so that the boxes 14 are not at risk of falling. Namely, the boxes 14 move on both sides of the thrust tracks 7 so that their position is therefore stable and the boxes 14 which roll on the rails 17c of the box organizer 17 are prevented from tilting by the other boxes next to them. The boxes 14 are thus also in a stable position on the rails 17c.

The boxes 14 advanced from the receiving section 7a move forward to catch each other until they stop at the end of the feeding section 17b, where the sensor 20 is actuated.

If, at this moment, the insertion member 19 is fully extended, so that the row of boxes in front thereof can be moved unhindered, the cylinder 18 will be immobilized on the stop 35 (Fig. 1), but with the insertion member 19 on the boxes impeded, it is unable to extend the entire row of boxes from the full width of the receiving section 17a, i.e. the number of boxes 14 on the feeding section 17b is an absolute multiple of the number of thrust tracks 7, the cylinder 18 on the guide 34 by force of spring 33 facing backwards. If the entire row of boxes from the receiving section 17a can be moved to the dispensing section 17b, then the roller 18 moves forward to the stop 35 as a result of the force exerted by the spring 33 (or weight). When the cylinder 18 is tilted backward, it is pneumatically prevented by its own operation and by the cylinder 15 of the bar 16.

When the sensor 20 detects that the entire row of boxes in the feed section 17b is closed, the actuator cylinder 22 actuates the lifting device 23 by rotating the closed box row from the dispensing section 17b to the dispensing table 26 rotating about the rotation axis 24. The side panel 26a serves to support the two extreme boxes 14 on both sides of the dispensing table 26. A possible adversely moving movement of the boxes 14 is prevented by the bar 29.

After the boxes 14 have been lifted, the lifting device 23 returns to its original position and allows the insertion member 19 to push the box row on the receiving section 17a back into the feeding section 17b,

It is important for the operation of the apparatus that

196 571

The Ion box box is delimited by a push bar 25 at the back, a crash bar 29 at the front and the side panels 26a from the side. The advantage of this solution is that although the flat boxes 14 on their sheaths are not individually stable, they are supported on all sides by such a closed row to form a perfectly stable finite length cylinder which can be considered as uniform. It is also important that the sensor 20 detects the presence of the boxes 14 only in the case of a completely closed row, so that the feeding is only possible in the case of a closed row.

When the bucket 21 reaches the feed position, preferably a pneumatic sensor activates the cylinder 28, which pivots the insertion bar 25 around the axis of rotation 27, thereby pushing the box row into the bucket 21. As the boxes 14 move as they move forward, the strut 29 moves about the axis of rotation 30 which, after passing through the row of boxes, is brought into its original position by the force exerted by the spring 31 (or weight). At this stage of the dispensing, the boxes 14 are positioned between the side guides 26a delimiting the feed table 26 on both sides and the insertion bar 25 pushes the box row upwardly against the gravity of the tray dispensing table 26 to ensure that the box row all members should be placed in the 21 goblets at the same time. As the row of boxes fills the known cup 21 across its entire width, there is no risk of the boxes 14 being disorganized (e.g., box tilting).
