Description

(54) DEVICE FOR LAYING PRODUCTS IN PACKAGES

one

This invention relates to bag forming machines.

A device for stacking products in packages is known, which contains a frame with vertical guides, in which a platform with a carriage for the product as well as a rail mounted for the carriage 1 mounted on the frame and installed on the frame with rails installed on it is installed.

The disadvantage of this device is its low reliability when forming stacks of large sizes.

The purpose of the invention is to improve the operating conditions and reliability of operation.

This goal is achieved by the fact that the lifting and lowering platform is made in the form of a plate on which up to additional trolley rails are installed, and the cable-block system is equipped with movable vertical rods having stops interacting with the cart and freely passing through the platform. vertical holes. At the same time, the length of the shtangi is greater than the height of the vertical holes of the platform by the amount of free running.

Such an embodiment of the device increases the reliability of its operation when forming large stacks and improves the operating conditions.

FIG. 1 shows the proposed device; in fig. 2 is a view A of FIG. 1. The device comprises a frame 1 with vertical guides 2 in which a lifting and lowering platform 3 is installed,

made in the form of a plate. The platform is fitted with rails 4 for the trolley 5. The lifting and lowering platform 3 receives movement from the actuator 6 by means of a traction element, preferably chain 7,

envelope asterisks 8-13. The cable-blocking system is equipped with suspended vertical rods 14 with stops 15 interacting with the carriage.

The rod is freely placed in vertical holes 16, made in

platform 3, the rod length being greater than the height of the platform vertical holes 16 by an amount a equal to the free stroke of the thermal element connected to it, which is determined by the drive braking time. Rails 17 are also mounted on the frame, along which the carriage 5 moves to the lifting and lowering platform. For installation of the platform in the lowest position on the frame, the supports 18 are fixed.

The device works as follows.

In order to form the package, the platform 3, with the trolley 5 installed on its rails 4, rises to the extreme upper position. On the cart 5, a row of boards is laid, after which the drive device is turned on, which, by rotating the drive sprockets 8 by means of chains 7, spanning the sprockets 9-13 and fixed to the fixed supports by their ends, lowers the platform 3 by an amount equal to the height of the laid row of boards . After that, the next row of boards is laid on the package.

As the bag size increases, the platform goes down on the rods 14. In this case, the stops 15 of the bolts enter the recesses of the carriage 5, fixing it relative to the platform 3.

After the formation of the package has been completed, the drive 6 is turned on, and the platform 3 is lowered down until it stands on the supports 18. In this case, the rails 17 are aligned with the rails 4. After installing the platform 1 on the supports 18, the drive 6 is turned off, but the chain 7 The arms 14 continue to move in the vertical holes 16 of the platform 3 by an amount a determined by the drive braking time. In this case, the stops 15 come out of the depressions of the carriage 5 and release it for free movement along the rails 4. Then the carriage 5 is carried out from the platform 3, and in its place the free carriage rolls on its other side.

After installation on the platform 3 of a free truck, the drive 6 is turned on to lift the platform using an asterisk 11

the rod 14 begins to move upward relative to platform 1 by the value of a.

The stops 15 enter the recesses of the carriage 5, locking it against movement relative to the platform 3.

With further movement shtang

platform 3 is removed from supports 18 and moves to the highest position where the formation of the bag begins.

The device makes it possible to form large, shtabel without reducing its reliability and improves the conditions of operation.
