Description

one

The invention relates to bag forming machines, in particular, to the design of a device for forming flat soft products, for example mineral wool plates, and can be used to form packages of flat products while further retracting stacks from one position in the direction coinciding with their supply.

The purpose of the invention is to reduce the size of the machine.

The bag forming machine for flat products contains an inclined ramny receiving conveyor 2 mounted on frame 1 and a feed roller table 3 containing rollers 4 and having a higher speed than the receiving conveyor 2. A roller table 5 containing rollers 6 is installed above the feed roller table 3. Receiving vehicle 2 , feeding rvlgang 3 and live rolls 5 form four stems of a non-consignment brook 7, 8, 9 and 10. On rollers 4 of the giving roll conveyors 3 of the most heavy load-carrying brook 7, rings 11 are mounted, increasing the diameter of the rollers 4 relative to the adjacent stream 8. Rollers 6 of roller table 5 are identical to rollers 4 and have similarly arranged rings 11. Rollers 2 and 3 are equipped with side guides 12 and 13. Side guide 13 near feed stream 7, roller table 3. Installed from the edge of this stream corresponding to the gap formed between the transported products along strands 7 and 8. The roller conveyor 3 is provided with a supporting wall 14 for restricting the movement of products during the formation of the stack 15 Lifting lowering mechanism for forming the stacks 15 from the lifting and lowering carriage 16 with forks 17, which have the ability to reciprocally move horizontally. The carriage 16 is installed in vertical guides 18 and connected to a drive 19. A rolling conveyor 20 is installed in the form of a chain conveyor 20, the section 21 of which is installed under the fork 17 and can be rotated around an axis 22. On a flat plane .

The bones with a chain conveyor 20 under the fork 17 are equipped with a two-speed accumulator roller table 23 intersecting with it at a right angle, at 5 than the frequency of rotation of the rollers 24 of the accumulating roller table 23 located under the forks 17 of the load-carrying stream 8, greater than the frequency of rotation of the other rollers 25. The height between the feed

10, roller table 3 and cumulative roller table 23 are larger than the height of pile 15. To stop piles 15 on cumulative roller table 23 while pulling the fork 17 out of piles 15, emphasis 26 is installed.

The bag forming machine works as follows.

Products, for example, mineral wool plates, flow along the receiving conveyor 2 chains in a continuous stream to supply roller table 3. The large speed of roller table 3, as compared to conveyor 2, distributes a continuous stream of mineral wool plates to transverse rows. On the receiving conveyor, the 2 plates move linearly. The inner side of the plates moving along the load-carrying creek 7 of the feed roller table 3 is accelerated by rings 11, and the plates are tilted to the side to rest on the side rail 13. The plates move along the m 8, 9 and 10 straight lines. Thus, the plates moving along the stream 7 are separated from the adjacent plates, forming a gap between them. The conveyor 5 facilitates the movement of the plates along the feeding roller table 3, facilitates the supply of the plates from the feeding roller table 3 to the forks 17 and serves to more reliably separate the plates moving along the outermost load-carrying creek 7. In the initial position of stacking, the carriage 16 with the forks 17 pushed in the upper position. The plates moving along the supply roller table 3 are superimposed on the forks 17 up to the stop in the wall 14 and are affected by a limit switch (not shown) which gives a signal to the actuator 19. The carriage 16 with the forks 17 is automatically lowered down by one step, equal to the thickness slabs. The rollgang 3 feeds another row of plates, which are lowered onto the previous row of plates already laid on the forks 17. In this way, the subsequent rows of plates are laid and form a stack 15 of a given

heights. When the required number is set in the stack 15, the carriage 16 is lowered to the lower position. In this position, the forks 17 are pulled out from under the stacks, slid into the carriage 16, together with it they rise up and again occupy the initial working position. A stack of 15 plates remains on the accumulation roller table 23 with the help of an abutment 26. The outermost stack of the stack of the stack 15 laid on the section 11 which is already separated by rings 11 acts on: a limit switch (not shown) including section 21, which rotates around axis 22 and rises above the accumulator roller conveyor 23. When raised, section 21 automatically turns on

chain conveyor 20 and the first pile 15, brook 7 leaves. Leaving section 21, stack 15 later acts on a limit switch (not shown),

from which the section 21 is lowered and includes the accumulating roller table 23. The next stack 15 of the stream 8 due to the high linear speed of the rollers 24 opens from the subsequent stack

The cycle of delivery of the stacks of 15 s of the additional roller table 23 automatically repeats until all the stacks have gone, for example, to the packaging. At the same time on the forks 17 form new piles.
