Description

one

The invention relates to devices for disassembling packages of lengthy products, in particular products of open box section, and can also be used for pairwise assembly of products, for example, with a view to their subsequent welding.

Devices are known for separating a package of articles, mainly of a cylindrical shape, by applying a pushing force at the end of the billet, which contains driving colliders. However, they do not provide layering products 1.

It is also known a device for disassembling and layer-by-layer dispensing from a package of non-circular profile products, comprising a lifting platform for laying the package, a pusher mounted on guides with the possibility of movement along the package, having a plate-shaped working surface with a straight lower edge oriented across the package, and a wall cutter with a straight upper edge located under the edge of the pusher parallel to the latter, rolling the end of the bag on the delivery side 2.

In the process of work, the pushing device, pressing on the ends of all products of the upper layer of the package, advances them above the upper edge of the cutter.

on the receiving conveyor. In this case, the ends of the products of the underlying layer abut against the slam-shutter, which prevents their possible mixing due to the friction of the adjacent layers. Then the pusher returns to its original position, the lifting platform sets the next layer of products to the removal level and the cycle repeats.

This device can only be used for layer-by-layer disassembly of packages with a straight line across the bundle by a layer of connector layers and does not provide for disassembling packages of products of open box section, for example, a trough-shaped (equal and unequal-serving), C-shaped, in the form of channel bars, since in these packages the lines connector broken due to the mutual overlap along the height of the elements of the profile of products located in different layers.

The purpose of the invention is to extend the technological capabilities of the device.

For this, the pusher is made in the form of a cantilever beam on which the teeth are fixed and a two-stage roller located on the iodine side to control the vertical position of the packages, the axis of which is parallel to the beam, and the cut-off device is in the form of a comb, the teeth of which are located with a gap under the teeth of the pusher.

FIG. 1 shows the proposed model Cii30, general view; in fig. 2 - section A-A of FIG. I; in fig. 3 - the position of the package of products-channel relative to the slider when removing the first upper row; in fig. 4 - the same as pa FIG. 3, when renting a second row; in fig. 5 shows an example of stacking various types of open box sections into a bag.

The OcHoeaiiHe device consists of a frame 1 and a rack 2. A lia frame 1 is mounted a lift. The platform 3 for stacking the bag. A support 4 is fixed on the rack 2, the axis of which is parallel to the direction of delivery of products. A movable pusher 5 is mounted on guide 4 in the form of a cantilever beam oriented across the bag, on which teeth 6 are fixed. Their number is equal to the number of products in the layer. The two-stage roller 7, mounted on axis 8, is connected to the collider beam 5 by the console 9. It is intended to control the vertical position of the bag by interacting with the surfaces of the products located on top and is axially positioned so that the cylindrical surface of the patient with dia The meter was located against the hollows of the profile of the products, and the smaller diameter was against the vertical shelves of the product, 1i (see Fig. 3 and 4). The distance from the lower edge of the teeth 6 to the lower edge of the beam of the collider 5, the difference in the diameter of the steps of roller 7, as well as its height in relation to the collider, are chosen so that when the cylindrical surface of the larger roller interacts with the horizontal wall of the product, from the top layer the edge teeth b from the end of the product overlap the thickness of this wall (see Fig. 3), and when a lower stage interacts with vertical shelves of products from the next layer, the lower edge of the collider beam I went below the edges of these threads (cf. Fig. 4).

The push rod 5 is provided with a reciprocating drive, and the platform 3 is equipped with a lifting drive (not shown). Both of these drives, together with roller 7, are associated with a control circuit (not shown in the drawing), which automatically stops lifting when the articles come into contact with the roller and the specified sequence of operation of the drives during the entire disassembly process.

The cutter 10, installed at the end, the package from the side of iodachi products, made in the form of a comb, the tooth 11 of which is located under the teeth of the collider with a gap greater than the thickness of the horizontal wall of the product (see Fig. 3 and 4).

The device works as follows.

Long products 12 open box-shaped profile is usually placed in packages, as shown in the fi | -. five.

Such a package with the help of workshops; the crane is mounted on platform 3, at the moment of loading platform 3 is in its lowest position, and push-button 5 is in its original position, at the rear end of the bag.

When the lift drive is turned on, the platform 3 moves upward until the upper row of products (see Fig. 3) touches the large diameter stage on the roller 7. In this case, a signal is given to the control circuit to stop the platform 3 and then turn on the movement pusher 5 in the direction of the packet. The tooth 6 pushes the upper layer of the products into the end of their horizontal walls, and the lower layer, abutting the tooth of the cutter 10, remains stationary. After removal of the upper layer of products, the Push-off 5 returns to its original position and turns on the lifting of the platform 3, which occurs until the vertical shelves of the products of the next layer touch the smaller diameter steps on roller 7 (see Fig. 4). In this position, the push-off beam 5 itself has a pushing effect on the ends of the product shelves, and the tooth 6 is freely placed in the cavity of the product.

In this way, the staggered implementation of the roller 7 provides automatic installation of the package on two different relative to the collider levels for the layer-by-layer removal of oppositely oriented products. With the help of a proposed device, it is also possible to carry out a pair-wise assembly of blanks from the upper and lower villages of the adjacent layers, for example, with the aim of welding them.
