Description

Fie. 17

The invention relates to packaging equipment and is intended for packaging piece products, e.g. devices, in cardboard boxes.

A machine for boxing piece products, for example medical bandages, is known, comprising a box-by-box feeding mechanism, a box conveyor, a product feeder, a box pusher device, valves for closing and opening valves, and an gluing device, a product collection mechanism. The products are fed by a feeder to a conveyor belt, where the collection mechanism groups the products into several rows. The flat-layered box blank of the inclined guides is then fed by suction cups to the conveyor, where the box is molded and the valves open. The grouped products are fed into boxes, then, using the devices, the valves of the box are closed and the box is ready to be pushed out onto an inclined tray guide for further feeding to the box 1.

A disadvantage of the known device is its low productivity, as well as the packaging of the product in an adhesive box.

Also known is an automatic line for packing cylindrical objects, comprising a conveyor, a chain conveyor parallel to it, a box forming and feeding device, a liner forming device, a hopper with feeders, a pusher for feeding the liner with articles into the box, a device for folding box valves and a device to remove the boxes from the conveyor. The line is also equipped with a device for monitoring the presence and integrity of products and a device for sticker parcel 2.

The flat blanks of the liner a are fed into the forming device and then stacked in conveyor carriers that move into the product stacking area (ampoules) therein. At the same time, boxes are formed from flat blanks.

The carriers with inserts and ampoules are placed in alignment with the boxes, are pushed into boxes with a pusher, then the side and front valves of the box are closed and the box is wrapped with paper tape. Packed and parcels are removed from the conveyor and fed to the stacker.

The disadvantages of the known line include low productivity due to the need to place the ampoules in the liner and place the latter in the box, as well as applying glue to the side flaps of the box.

5 Closest to the claimed

the object is a machine for packing groups of pieces of goods, for example small fish, containing a carton for cardboard blanks, an apparatus for dispensing them individually, guiding and feeding rollers, a box forming die, a guiding funnel, a conveyor for moving boxes; mechanisms for sealing valves of boxes; and mechanisms for closing the upper valve with heat-sealing tape 3.

Intermediate rails 75 are provided for moving the packs from the grouping mechanism 62 to the collision mechanism 71.

The automatic line is controlled by a microprocessor (not shown).

- Lini works as follows. The cardboard blank 7 from the cassette 6 is fed under the punch 8 and the matrix 9 of the mechanism for forming picture packs 5, where it is formed and with the open top and bottom valves mounted on the conveyor 2 mounted on the frame 1, where it is caught by the stop 3 of the moving conveyor 2 from the drive 4 .

All operations are carried out with the conveyor stopped.

The formed pack 10 is moved by the conveyor 2 to the stacking mechanism 11, where the packaged product by means of a vacuum gripper 12, mounted with the possibility of rotation on the axis 14, is captured by the suction cup 13 from the feed conveyor (not shown) and using the movable rod 15 of the pneumatic cylinder 16 of the horizontal reciprocating the movement and the vertical return drive 17 of the reciprocating movement is stacked in the stack 10. The vacuum pickup 12 with the suction cup 13 is returned to its original position.

Upon subsequent movement of the conveyor 2, the bundle with the product is fed to the marking mechanism 18, where

applying paint to the front surface of the top of the pack 10. For marking, the rod 24 of the pneumatic cylinder 25 of the horizontal actuator moves the plate 22 fixed on it, which interacts by means of the springs 23 on the housing 20 with the cliché 19 to the upper valve moving on the guides 21 in the holes of the plate 22. cardboard pack 10

for marking. Before marking, the cliche 19, together with the horizontal displacement drive, is rotated 90 ° with the help of the rotation device 26 to the stamp pad

27, interacting with it, wetted with paint and returned to its original position for marking on the subsequent pack.

With further movement of the conveyor 2, the cardboard bundle 10 is supplied to the end flap mechanism 28 by 90 °. In this case, the binder 31, mounted cantilever on the axis 30, when it is rotated using the two shoulders lever 33,

connected by an axis 34 to the rod 35 of the pneumatic cylinder 36, contacts the curved plate 32 fixed thereon with the valve of the packet, bending it by 90 °, and then returns to its original position.

At the same time, the front end valve bends by 90 ° 37 with the help of the guide 38 and the spring plate 39, mounted on the brackets 49.

a guide 38 and a plate 39 will fix both end valves. Next, the bundle 10 moves to the bending mechanism of the tab of the upper valve 41, the passage between the two fixed guides 42 and

43. In this case, the L-shaped plate 44 hinged on the axes 45 and 46 when it is turned from the rod 47 of the pneumatic cylinder 48 is in contact with the tab of the valve, bending it on the guide 43, and then returning to its original position.

Subsequently, when moving the pack 10 to the mechanism 49 of closing the top of the pack, the plate 50 is cantileverly fixed on the hinged axes 51 and 54 during its rotation

down from the rod 55 of the pneumatic cylinder 56 presses on the top of the pack, bends it down, and the tab of the valve at this time is in contact with the surface of the curved guide 53.

At the end of the rotation, the plate 50 mounted on the bracket 52 acts on the end of the lever 61 of the device 57, which during its angular rotation moves forward the spring-loaded spring

60 threaded stop 59, which

when moving, presses on the front wall of the pack 10, allowing the lock to enter the notches of the tongue of the upper valve. The top of the pack 10 is locked into the lock. After this, the plate 50 with the bracket 52 is returned by the rod 55 of the pneumatic cylinder 56 upwards, and the threaded stop 59 with the lever 61 is returned to its original position by the action of the spring 60.

The product-filled and closed pack 10 is conveyed by conveyor 2 to a grouping mechanism 62, where the finished packs coming down from the conveyor, abutting against one another, are moved by conveyor 2 on table 66 to the guide 69 and abut against it. The row width is set using rails 69 and 70, mounted on axles 68, mounted in struts 67. After a predetermined row has been set, the pneumatic cylinder 63 with the rod 64 moves the group of packs pusher 65 one step equal to the row width.

Subsequently, grouped rows of packs of two lines are fed in rows to intermediate rails 75 and then to collision mechanism 71, where they are grouped into a predetermined number of rows and are pushed by pusher 72 using rod 73 of pneumatic cylinder 74 into a container (not shown).

The cycle repeats.

Line operation is controlled by a microprocessor (not shown).

The proposed design is simple, it allows to increase productivity, reliability of the line, improve the appearance of packaging, and switch to a new type of organization of packaging production.
