Description

I

The invention relates to devices for putting safety corners onto a bag when wrapped with a metal tape. It can be used in the woodworking, paper and other industries.

A device is known for applying safety corners to a bag. products for ILJ.,

This device is not entirely reliable in operation and has a complex structure.

Another similar device is also known, comprising a conveyor for feeding a package of articles, cassettes with upper and lower guides for the angles and pushers.

This device is difficult overlapping corners on the package of products.

The purpose of this invention is to facilitate the overlapping of the safety corners on the product package.

To achieve this goal in a safety device

corners on a package of products containing a conveyor for supplying a package of products, cassettes with upper and lower guides for angles and pushers, two rods along the conveyor are attached to each guide and two grooves for rods are formed on the corners. At THIS, the guides are mounted on the fingers with the possibility of rotation in the horizontal plane, the upper ones of which are reinforced with the POSSIBILITY of rotation in the vertical PLANE, and the lower guides and rods have a helical shape.

FIG. 1 shows a general view of the device; in fig. 2 - top view; in fig; 3 on a larger scale, partly view A of FIG. one; in fig. 4 - view B of FIG. 2; in fig. 5 - section BB of FIG. four; in fig. 6 a section of the GGD FIG. five; in fig. 7 is shown on an enlarged scale with the safety corners and elastic ends of the landmarks installed; in fig. 8 shows a section of DD-D. 7; in fig. 9 shows the angle setting mechanism. The device consists of a lamellar conveyor 1 with a star, 2, 3 (Fig. 1), two mechanisms for placing the upper safety corners and two mechanisms for laying the lower right angles of preservation. Each of the first mechanisms consists of the cassette 4 and the upper guides 5 (Fig. 2), and each of the second mechanisms is from the Cassette 6 and the lower guides J7. Any of the mechanisms is equipped with a core 9 mounted on the housing S, the piston rod 10 of which has a pusher 11 that moves freely in the groove a between the cartridge 4 or 6 and guides 5 or 7. The dimensions of the groove a are adjusted by screws 12 (Fig. 3). Landmarks 13 and 14 (Fig. 2, 7) in the form of rods are attached to the corners 15 (Fig. 3), which are rigidly connected to the housings 8 (Fig. 1). The free ends of the landmarks 13 and 14 are made of elastic, with a reduced diameter. To tighten the safety corners 16 (Fig. 7), spring-loaded strips 17 (Fig. 3) serve. Guides 5 (Fig. 2) for overlapping the upper safety corners 16 are attached to the fingers 18 sharnshzno, and guides 7 for fastening the lower safety corners 16 are rigidly connected to the fingers 19. The fingers 18 and 19 are inserted into the clips 2O (Fig. 2), which have the ability to rotate in a limited horizontal plane due to the support 21 and the screw 22 (Fig. 5). To limit the rotation, there are stops 23, installed in harnesses 24 (Figs. 2, 4, 5). The guides 5 and 7 are constantly pressed against the stops 23 by springs 25 (Fig. 5), which ensures the whole device is springy through the width of the package 26. Each of the housings 24 (Fig. 3) is hinged on the cup 27 with internal thread, The screw is mounted on the screw 28. When the arms are turned to -29, the guides 5 and 7 are raised or lowered. The ZO column prevents the spontaneous displacement of the housing 24. The pins 3 are pressed into the fan 18 (Fig. 6), which enter the guides 32 5, which provides the oscillating aviation of the latter in a vertical plane bones to compensate for deviations of packages 26 in height. The constant covering of the valves of the package 26 is carried out by the rollers 33 (Figs. 1, 3), which are suspended on plate springs 34, mounted on rods 35 (Fig. 1-3) attached to the housings 36, and the housings 36 are rigidly connected with cups 37 (Fig. 3), having internal thread, and mounted on screws 38. Rotate the handle 39 to set the rollers 33 relative to the height of the bag 26 .. To prevent the boom 35 from turning, there are columns 4O. The device is mounted on a fixed | Noy crossmember 41 (Fig. 2) and a movable 42 with screws 43. The euddies 2 and 3 can be moved along shafts 44 and 45 (Fig. 2), which allows changing the width of the conveyor 1 and adjust the position (Mechanisms for installing the corners 15 across the width of the packages 26. Limit switches 46 and 47 serve as a signal for the actuation of the pneumatic cylinders 9 and movement of the conveyor 1 (Fig. 2). The binding material is tape 48. All four mechanisms for installing safety corners work on the same principle. Protect The corners 16 enter the guides 5 and 7. In the initial position, the angles 16 should fill the guides 5 and 7 along the entire length. At that, the landmarks 13 and 14 are located in the recesses b (Fig. 7) of the corners 16. When the next the package 26, moving together with the conveyor 1, presses the limit switch 46 (Fig. 2), the signal stops the conveyor 1 and all the pneumatic cylinders 9 simultaneously operate, the rods 10COTO: are pulled in and the next safety corners are knocked out of the cartridges 4 and 6 16. Forward corners 16 move to one n step forward. Extreme corners are soskal, zayvay with guide%; x 5 and 7 and fall on loose with reduced diameters ends of landmarks 13 and 14, which allow you to tie the package 26 with tape 48. After the first tie, the conveyor 1 moves the package 26 further up to the contact | with the limit switch 47. The described process is repeated. The finished package is removed from the conveyor 1. The dressing is performed by a belt-forming machine (not shown). The lower safety corners 16 move in a helical path and rotate 90. The limited rotation of the directions 5 and 7 in the horizontal plane and the rocking movement of the guides 5 in the vertical plane compensate for the effect of permissible variations in the width and height of the package on the operation of the device. The mechanization of placing the safety corners on the packages before their i-wrapping with a metal tape allows eliminating manual labor and providing safety measures, since manual overlapping of the corners presents the danger of workers' fingers getting under the tape at the time of the package binding. Forms of the invention 1. Device for putting safety corners on a package of E1 products to binding machines, containing trans. a spider for feeding a package of products, cassettes with upper and lower guides for the angles and pushers, which are designed so that, in order to make it easier to apply safety locks to 986 angles of the bundle, the npyTiea are attached to each rail. , - dispersed along the conveyor, and at the corners are formed vectors for bars. 2. Device by. l, differing from Eo e e with the fact that the letters are mounted on the fingers with the possibility of rotation in the horizontal plane. 3. The device according to claim 1, in respect of the fact that the upper guides are installed with the possibility of rotation in a vertical plane. 4. The device according to claim 1, in accordance with which the lower guides and rods are helical. Sources of information taken into account during the examination 1.
