Description

The invention relates to the food industry, and in particular to food packaging technology, and can be used to supply paper packaging tape for sealing cardboard boxes (corrugated boxes) with refined sugar.

A device for enveloping cardboard boxes is known, comprising a frame, upper and lower cassettes located one above the other for wrapping mechanisms with knives, each of which consists of an endless flexible tape placed on drums mounted to adjust their position along the frame, and at least three spring-loaded rails mounted on the tape, in which the knives are installed. A disadvantage of this device is the need to stop it when reloading cassettes, which leads to a decrease in water drainage.

A device for supplying packaging tape for sealing boxes is known, comprising a main and an auxiliary bobbin onto which packaging tapes are wound, and at the place where the ends of the tapes are joined, a feeding mechanism for the connecting tape and a knife are cut.

The disadvantage of this device is the need to stop the device when introducing the main reel, which also leads to a decrease in productivity.

The aim of the invention is to increase the productivity of the device due to the possibility of replacing the bobbin during operation of the device without stopping it.

This is achieved by the fact that in the device containing the base, the vertical rack, the reels for packaging tapes mounted thereon and the mechanism for gluing the ends of the tapes, the gluing mechanism includes a vacuum-gripping end of the tape, mounted on a carriage mounted with a reciprocating movement

along the guides along the tape feed direction, and an adhesive nozzle disposed between the bobbins.

In FIG. 1 shows a device; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section BB in FIG. 1;. In fig. 4 is a section bb in FIG. 1; in FIG. 5 / green I in FIG. 1.

The packaging tape supplying device for sealing boxes contains a flat base 1 (Fig. 1, 2, 3) with a vertical stand 2, on which, through the axis 3, the main reel 4 with the tape 5 is mounted, and through the axis 6, an additional reel 7 with the tape 8. In addition, the guide rollers 9, 10, 11, the nozzle 12 for supplying glue, located between the reels 4, 7, the stop 13, the support 14 of the tape 5 and the support 15 of the tape 8 are fixed on the rack 2 with brackets (Fig. 1, 4 ) with a spring-loaded movable clamp 16, consisting of a rod body inside it with vertical plates minutes with a bevel in the upper part and a horizontal roller at the bottom for holding the strip end 8.

Under the bobbins 4 and 7, tape recorders are attached to the bobbins, which are spring-loaded levers 17, 18 with one end of the lever touching the roller of the corresponding bobbin in the presence of tape, and the other sensor in the absence of tape.

At the top between the reels 4 and 7 there is a mechanism for gluing the ends of the tapes, including a vacuum grip 19 (Figs. 1, 2, 3, 5) of the end of the tape, mounted on the carriage 20, mounted with the possibility of reciprocating movement using the side rack 21 and gear 22 along the guides 23 along the tape feed direction.

The vertical movement of the vacuum capture 19 is carried out by means of a pneumatic cylinder 24 along the guides 25 with a connecting bar 26. A sliding slider 27 is installed from one end of the vacuum capture housing 19, which is in contact with the stop 13 of the rack 2 in the extreme position. using the washer 28 and the seal 29 is connected to the spring 30.

Two vertical holes 31 and horizontal channels 32 connected to channel 33 are drilled in the slider. The housing below has eight vertical holes 34 and horizontal channels 35 connected to the central channel 36 with hole 37 and outlet 38 to a vacuum pump hose (not shown), on the side of the case there is a bar 39 with a bevel at the bottom, which acts when the carriage 20 is moved near the reel 7 to the vertical clamp plate 16.

The device operates as follows. The main reel 4 with a tape 5, which is passed through the guide rollers 9, is manually mounted on the rack axis 3.

the gap between the support 14 and the vacuum gripper body 19 with the slider 27 to the rollers 11 and further to the sealing mechanism is not shown). An additional bobbin 7 is installed on the second axis 6 with a tape 8 passing through the guide rollers 10, a gap between the support 15 and the horizontal roller of the vertical plate of the spring-loaded clamp 16.

After starting the sealing mechanism 5, the tape 5 is unwound from the reel 4, while the spring-loaded lever 17 rotates around the horizontal axis of the bracket and touches the sensor in the extreme position when the ribbon is used up

0 5. Next, a command is given to the intermediate relays and, upon reaching the end of the tape 5 of the rollers 9, the vacuum pump drive is turned on, which sucks air through the hose, exhaust 38, central channel 36. channels 35, vertical hole 34, and by creating a vacuum tape 5, pressed against the holes 34, is held by the vacuum gripper body 19. A gear drive 22 is connected in series with the rack 21,

0 and the carriage 20, together with the pneumatic cylinder 24 and the vacuum gripper body 19, moves along the guides 23 to the additional reel 7, releasing the spring-loaded slider 27 from the stop 13, while the hole 37 of the central channel of the housing coincides with the channel 33 of the slider, channels 32 and vertical holes 31, and by creating a vacuum, the end of the tape 5 is pressed against the holes 31,

0 held by slider 27,

At the same time, compressed air and adhesive are supplied to the nozzle 12, which lubricates the tape 5. After moving the housing with the vacuum gripper slider with tape 5

5 near the nozzle 12, and the speed of movement of the carriage 20 is the same as the speed of passage of the tape 5 in the sealing mechanism, the supply of compressed air and glue to it is stopped.

0 When moving the carriage 20 near the clamp 16, compressed air is supplied to the pneumatic cylinder 24, which lowers the vacuum gripper 19 with the slider 27 and the tape 5 to

5 in contact with the tape 8 located on the support 15, and with the help of the strap 39 of the vacuum gripping body 19, the vertical plate of the clamp rod 16 is moved together with the roller and releases the beginning of the tape 8, which is glued to the tape 5.

Then, the vacuum pump is turned off, the rod of the pneumatic cylinder 24 lifts the vacuum gripper body 19 with the slider 27 to its previous position, the carriage 20 is moved to the initial position until the slide 27 contacts the stop 13 with the help of the pinion gear 22.

The sealing mechanism continues to unwind the tape 8 from the bobbin 7, the clamp 1 b spring returns to its original position.

The reel 4 is manually manually mounted on the axis 3 with a tape 5, which is passed through the rollers 9 into the gap between the support 14 and the vacuum housing 19 by the slider 27.

Moreover, when unwinding the tape 8, the spring-loaded lever 18 rotates around the horizontal axis of the bracket and touches the second sensor in the extreme position when the ribbon 8 is used up.

In this case, the above technological operations are repeated, and the switching on time of the intermediate relay is determined from the condition of finding the carriage 20 with the vacuum gripper body 19 with the slider 27 when moving near the rollers 10 only with the end of the tape 8.
