Description

The present invention relates to an apparatus in which the containers which arrive in a straight line perpendicular to the main movement of the machine, are preferably arranged in a so-called loading head into multiple rows and then transferred to the carton by transferring the layers over a so-called drop tool.

Each layer is formed, moved or delayed by a full automatic cycle.

Below the loading head is a discontinuous carton conveyor track, actuated by a pneumatic cylinder, with open-lid carton boxes moved there.

The drilling tool, which receives the formed layers, is a flat plate 90 ° downwardly open in a controlled position and controlled by pneumatic actuation in two positions rotated on two rotary axes.

The optimum position between the carton and the drop tool is provided by a sensor-controlled carton transport path, which forms an integral unit for the consistency of their control with the above-mentioned loading head.

Other devices known for stacking bottles, cartons in cartons are known, which are generally suitable for similar purposes, such as placing containers in a carton or by holding the containers / glass, bottle, box, etc. / from the top, horizontally it is pulled out of the containers and placed in an open cardboard box already on site. Alternatively, the containers have a truss frame underneath the base of the containers, which, after the containers have been formed, are pulled by half the diameter of the container and are generally dropped into 4 cartons per container. Any known solution applies one of the above principles. The arrangement of the containers, whether it is a drop or a top catch, is similar in solution.

-3 Similarities, eg, that one-liners / glass, box, etc. / are either inflated by pneumatic or geared mediated paths for multi-line transmission. In some embodiments, dropping the containers is completed by raising and lowering the carton at the same time. Structurally, such machines are more complex, more expensive, and have more failure points, but do not increase their performance.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the drawbacks of known carton-laying machines, namely to reduce the degree of complexity by more expedient solutions, to provide novel structural elements, e.g., cardboard dropping, carton transfer, in a complementary manner. the advantageous design of the loading head and the carton conveyor, and the special design of the drop tool, may allow for a lower layer formation than any known device. This fact makes it possible to transport containers at the technological level, which simplifies the alignment of the equipment.

The present invention is based on the discovery that when the container feeder conveyor elements / solder chains are self-vibrated in the row distribution zone and the uniform container row is transported long enough from the conveyor to a flat sheet and a desired amount of flat sheet arrival receipt controls the lowering of the answer sheets and controls the container stack from here

- a transverse sliding plate from 4 receiving locations pushes the containers across the entire stack width and then, in a second step, pushes the stack of containers onto the downward-opening pair of knives where the presence of the stack is detected and partly against the first stack of containers fixed and thereafter the so far horizontal door-like dropping device is opened about 90 ° above the open carton of the carton transport path to drop the containers into the carton, then a container-controlled L / D> 1 container working.

Further advantages of the carton laying apparatus according to the invention are as follows:

Once the number of rows per row corresponding to the load number has been reached, the path of the rows of rows towards the drop tool is started only when the row sensors controlled by the first rows of rows pick up their position pulls a pneumatic cylinder vertically below the plane of the table. This construction of the railing also results in the necessary transverse loosening of the container loads.

Controlling the unit is simple as each stroke is controlled by a vessel.

The space requirement of the equipment is less than 6o-7o% of the known equipment.

Figures 1 and 2 show that the apparatus of the present invention consists of two stacked units with conventional belt feeds, the container organizing and dropping unit, such as a loading head and a cardboard transport path beneath.

The carton transport track 9 is located below the drop head 6 of the loading head such that their geometric axis is in the same plane. Part of the carton conveyor track 9 is an endless twin roller chain 14 connected to sprockets wedged on bearings. The distance between the even chains 14 is such that it is more than the width of the carton to be filled. The chain members 14 are provided with cardboard conveyor crossbars 15 at intervals greater than the length of the cartons.

The carton conveyor rods 15 run above the slide 17 of the conveyor 9 so as to provide thrust at the optimum point for conveying the carton. Out of the gap in the sliding plate 17 is a hanger for positioning the cardboard box 16 which can be tilted with a pneumatic cylinder. The carton is positioned interposed between the transverse rod 15 and the cardboard overhang hook 16, and the conveyor 9 moves intermittently along the conveyor 9 as follows. In one of the transverse rods 15 in the lower limb of the pair of endless roller chains 14 The roller chain 14 moves with the pivot 15 through the air cylinder 12, and then the air cylinder 12 can reset the conveyor belt 11 to a new position. The electromagnetic brake 13 and the positioning hook 16 in front of the carton are used to prevent the cardboard passage through the crossbar 15, and there is an adjustable limit on both sides of the carton adjusting track 9 for the relative clearance of the carton. The runway 9 is equipped with a so-called sensor light barrier 10 to detect the positioned arrival of the carton and then indirectly initiate the dropping of the containers. The so-called loading head is used to receive pots sorted by the answer sheets on the organizer tape,

The first part of the container head for the flow of the container is the container hanging device. The purpose of the container hook 2 is to catch the tamping pressure of the organizing belt 1. This structure is configured to have lower, upper pivoting pivots, numbered by a number of rows, and moved by a pneumatic cylinder driven by a top-mounted, flattened push rod and fork-like arms. If the pages are approx. Rotate 30-45 ° to seal the path of the vessel and prevent the vessel from entering.

The second important part of the loading head is the movable rail 3 which alternately moves up and down in the slit table 25. The function of these movable rails 3 is to enable the slots 25 on the table, i.e. the passive section, to allow for vessel arrangement and layer formation. The moving barrier 3 is a suitably designed structure which is moved on guide rollers and has a separating plate corresponding to the layer to be formed. Its up and down movement corresponds to the state of the container rack for layering or preparation for insertion. In the lateral part of the moving railing unit 3 there is provided a sloping guide track which is intended to operate the tilting barrier 24 described below.

- The third important part of the loading head is the tilt bar which also performs row sensing 24. This unit performs a collision of the vessel flow as well as an accurate detection of each line. Its function is to signal the insertion of the formed layer and to loosen the pre-insertion layer. The swinging bar 24 is pivotable on a shaft by means of a bearing. Its fixed position is defined by the position of the moving rail 3 as defined by the slope of the slope 28, and its relaxed state by the slope 28 of the moving rail 3 as follows:

The pivot bar 24 is moved or locked by a lever mechanism 29 by holding one leg of the arm on the pivot bar and the other leg being rolled against the forced path 28 of the movable bar 3. The lever mechanism may be actuated by a spring if the movable rail 3 moves downward and reduces its tension by the downwardly sloping forced path 28. Thus, the position of the moving rail 3 below results in the displacement of the tilting rail 24, i.e. loosening of the underlying layer. This condition corresponds to the stress-free insertion of the layer.

The fourth important unit of the loading head is the dropping tool 6. It carries out the container layer in a cardboard box with the following structural solution:

The dropping tool 6 consists of two opposing plates, the ends of which are circularly delimited from one side to the other and partly rotated about their axes.

The dropping tool 6 occupies a pair of horizontal positions in its basic position, allowing it to be moved over the container layer. The droplet number 6 may be displaced by 90 ° from its base position when actuated by the air cylinders 19, which is the so-called opening position.

The main advantage of the dropping tool 6 is that, as illustrated in Figure 6, it solves the problem of dropping the container into cardboard at the moment of dropping. Thus, from the side, the circular articles, and in the longitudinal axis, the tilting plate itself, leads the container to the container.

This fact, in turn, makes it possible to reduce the level of layer formation, which is one of the most advantageous aspects of linearizing an equipment.

Functional description of carton-laying equipment:

By way of example according to the invention! an apparatus for preferably dropping / filling a filled container into a carton of L / D > 1 operates as follows.

After commissioning of the device, all functional units of the carton transport path 9 and the loading head 6 are reset, namely, the hopper hook 2 in the line of the handrails, the movable handrails 3 in the rear position, the hopper depressor 7 in the upper position and a couple of horizontal planes.

The sorting belt 1 feeding the apparatus is moved by its gear in the direction of the arrow. Containers from the filling or labeling machine are congested on the belt 1 and then arranged in several rows between the boundaries of the belt 1 and a sufficient number of containers formed by the belt movement creates a pulling force such that the containers move beyond the container rack 25 within the movable limits 3 towards the inductive line sensor 4. When each of the vessel rows reaches all the sensors of the inductive row sensor 4, this means that the desired amount of vessel, according to the row and the number of pieces per row, is ready for the first operation cycle of the loading head 6.

-10 The operations of the first cycle are as follows:

The row sensors 4 triggered by the pots provide a signal to the air cylinder 20 which operates the pots 2 and pivot the vertical pivot pins with the pivoting pin 3o-4o, thus reducing the width of the tracks to the half-diameter of the pits. Following the control, the movable rails 3 protruding from the slots 25 from the table are pulled by the pneumatic cylinder 26 below the plane of the table 25 and at the same time tilted the row sensors 4 by mechanical constraints to release the row of vessels as stacks. Following the tilt of the row sensors 4, the liner 5 pushes the container stack at a value perpendicular to the arrivals of the containers, namely toward the drop tool 6, by means of the air cylinder 18, and the liner 5 moves back to its home position. Upon return of the insertion plate 5, the row sensor 4 tilts back to its original position, the movable rails return to their original position above the slotted table 25, and the pot racks 2 recline to the line of the guide strip 1. This completes the first cycle. The baseline described above corresponds to the initial baseline of the first cycle and begins with the second cycle of repeating the same cycles as in the first cycle.

The stack of containers moved by the liner 5 pushes the container / stack / container in the intermediate position to the tilting faces of the drop head 6.

-11 The infra-barrier 8 over the drop tool senses the pushed row of vessels and controls the air cylinders 21 operating on the hopper level 7 to move downwardly to secure the first row of containers following the hopper load above the drop tool 6 against the tilt. 8 Infra-barrier above the drop tool does not act as a control for dropping containers unless the following conditions are met, which are:

The transverse rods 15 between the pair of endless roller chains 14 under the dropping tool 6 and perpendicular to the main movement of the carton conveyor 9 are divided by more than the length / manual control of the carton or by the step 6 . By placing an open carton box on top of the slide 17 of the conveyor 9, the step / step / movement of the carton is repeated until the first blade of the carton reaches the carton sensor infra barrier 10. The position of the barrier 10 is such that it stops moving the box at the optimum position below the drop tool 6 and activates the carton box positioning hook 16 to prevent the box from overheating,

By actuating the carton conveyor path 9 as described above, a position is created such that the simultaneous control position of the carton sensor 10 and the infra barrier 8 above the dropping tool actuates the air cylinders 19 of the dropping tool 6.

The two horizontal plates of the dropping tool 6 are tilted downward by about 90 ° and the containers thereon fall into the open carton and then the plates are tilted to a horizontal position by the air cylinders 19. The carton transport path 9 moves forward with the loaded carton and another empty carton is placed in the filling position. The carton conveyor track 9 stops its incremental movement until the loading head 6 has completed the cycles already described, namely, the container stack is not formed above the drop tool 6 and is not dropped into the new empty carton box. The repetition of newer cycles is described above.

In principle, if there is no cardboard box under the dropping tool 6; no drop operations ·

The automatic mode can be adjusted manually per cycle. For example, in case of tilting of containers, possible folding of cardboard box covers etc.
