fan. Between the inner and outer wrappers are sometimes embedded liner made of thin cardboard. On the front sides of packs podvertka wrapped pleated envelope with a lock, and the bottom edge of the paper stack labels are glued together.

The machine consists of the following main components: the frame 2, a feeder for a packaging material 1, feeder for 8 products chain conveyor 7, 6 feeders products for wrapping, forming 4 device system of longitudinal and transverse podgibateley 5, conveyor 3, discharging packaged products.

The diagram of the semiautomatic operation is shown in Fig. 10.15. Products are placed manually in the loading shafts 8 product feeder. The bottom of each shaft is the pusher plate 16, reciprocating in the horizontal plane. Moving to the center of the chain conveyor 9 (working stroke), during its stopping, the pushrod pushes several items out of the shaft, placing them in the nests of the chain conveyor. Then the conveyor moves to the next position, where a few more pieces are moved from the other shaft and are located above those already in the conveyor's nest. From the third shaft, a few more products are also delivered in the same way.Process automaton circuit K-467

Thus, in the nest formed by the conveyor stack of articles.

Three other shafts disposed on the other side of the conveyor, likewise filled with the second row of the conveyor slots.

The thickness of each plate-pusher 16 is equal to the height of the stack of articles fed into the carrier cavity. So, if the stack consists of five articles, then the first plate of a thickness equal to the height of the two cookies, feeds two items to the conveyor cavity. The second plate likewise feeds two more products, the height of the plate being such that the products fed by it are located above the articles supplied by the first plate. The third plate supplies one more product, placing it over four already placed in the nest of the conveyor. The collected stack of products, located in two adjacent nests of the conveyor, is fed to the wrapper.

Initially, the product is applied preform packaging materials. Labels are stacked in 14 store. Vacuum suction cup bends the edge of the bottom label and cutter separates it from the stack. Last wherein the weight is held in toothed blade. Then 12 forceps grip end of the tape 13 podvertki and separated from the foot of the label, and transferred them to the product.

On the way of the label movement, there is an adhesive roller that applies a strip of glue to the edge of the label. When the forceps 12 pass a distance equal to the length of the cutting of the swivel, they stop and the 15 shears cut the swath blank from the 13 tape. At the same time, the stamping mechanism punctures the date of the wrapping on the label. Continuing the movement, the 12 forceps apply the wrapper blank to the products, which are then lowered by the upper clamp 6. Clamped between the lifting table 7 and the upper clamp 6, the wrapper products rise up through the fixed forming matrix 5. In this case, the free wrapping fields on the four sides of the product with the plates of the 5 matrix are bent downwards, and then the wrapped valves formed from the wrapper by the 11 shaped guide 5 arrays are pressed against the ends of the article. A box with an open bottom forms around the product.

When the article is stopped in an upper position, the side podgibateli 10, operating sequentially laying wrapper with two sides of a base product. Further rear podgibatel 4 produces a similar operation on the downstream side of the article.
