Description

The invention relates to equipment for packing bulk materials, namely, automatic devices and manipulators for feeding and putting on valve MeiiJKOB on the horns of a carousel packaging machine in various industries, for example, cement, chemical, food, etc.

The purpose of the invention is to simplify the design and increase reliability.

FIG. 1 shows a device for putting valve bags on the horns of a carousel packaging machine; in fig. 2 is a view A of FIG. G; in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. 3; in fig. 5 is a view of FIG. four.

The device comprises a frame (housing) 1, a conveyor 2, which together with the frame also performs the role of a magazine for empty valve bags 3 and a ratchet mechanism 4 for transmitting movement to the conveyor 2. On the frame is fixed a lifting mechanism 5 of slides 6 for lifting empty bags 3 from the conveyor at iiOMou.i, H of the knot 7 on the carriage 6 and the cut-off device 8 for pressing the front bag on the conveyor to the knife 7 in order to guarantee gripping and lifting the bag to the valve with a knife. The frame is equipped with a 9 dl drive for transmitting the rotation to the fixed roller 10 and guides 1 I for guiding the movement of the bag 3 when it is put on the horn 2 of the carousel packing machine 13. Next to the fixed roller 10, a movable wave 15 is fixed on the lever 14, which, together with roller iO, serves for feeding (putting on) mep. 3 on the horns of the 12th packaging machine.

A drive unit 16 is mounted on the frame for transmitting movement through ball transmission mechanisms 17-21, respectively, to the ratchet mechanism 4 of the conveyor 2, the mechanism 5 for raising the carriage 6, the lever 14 of the rolling roller 15 and two identical slam-shut devices 8.

The drive unit 16 has a cam distribution mechanism 22, which controls, through ball transfer mechanisms, the operation of these mechanisms and devices, the aiming gear 23 for transmitting movement from the packaging machine 13 to the drive unit.

The device contains a locking device for automatically passing the horn (i.e., avoiding putting on the bag) occupied by another bag.

The locking device consists of a rotatable spring-loaded lever 24 with a profile cam 25 (Fig. 3), having an axis of rotation 26 in the bearing support of the base 27, fastening above the direction 11 of the device. A spring 28 is attached to the lever 24 to return the lever to its original position. For fix

Nor does the initial position of the lever 24 serve as a stop 29.

The cam 25 is all the time in contact with the roller 30 fixed at the end of the pusher 3 mounted in the supports 32 with the possibility of mixing along its axis in the horizontal plane. The supports 32 are fixed on the base 27. On the pusher, the stop 33 is fixed, which at one end can interact with the lever 14 of the movable roller through the bar 34 (Fig. 4 n 5).

A safety spring 36 is installed between the pusher 35 of the ball gear 19 and the lever 14 of the rolling roller, on which the pusher 35 acts through the gasket 37 (Fig. 5).

The device works as follows.

In the case of a carousel packing mill 13, movement from it through the pin drive 23 of the drive device 6 is transmitted to the cam distribution mechanism 22 of this device. From the cam mechanism 22, the movement is distributed to the ball transfer fur l: H; rg.y17-21. First, from the ball mechanism 17, through the ratchet mechanism 4, the conveyor 2 moves m: another 3 to the mechanism 5 for lifting the cam 6. 6. Next from the ball mechanisms 20 and 21, two intercepting devices 8 are activated, which cut off the bag part from the whole pack on the conveyor in order to press the front bag to the fire 7 of the carriage 6. At this time, the carriage 6 starts to lift from the ball mechanism 18, which press 7 picks up before MeuJOK 3 by the valve and lifts it from conveyor 2 into the mai i direction. in this case, the bag is mounted between the fixed roller 0 and the movable roller 15 (Figs. 4 and 5).

From the ball mechanism 19 through the lever 14, the movable roller 15 presses the bag 3 to the rotating wheel 9 from the drive 9 by means of the fixed roller 10. Due to the rotation, the rollers 10 and 15 eject and put the bag 3 on the horn 12 of the packaging machine 13. After this, due to the spring return, ratchet rellechanism 4 , the cut-off devices 8 and the lever 14 with the movable roller 15 are brought to their original initial position, and the lifting mechanism 5. The driving wheel returns to its original position due to the weight of the carriage 6. Later on, to put the new bag on the next horn, the work cycle repeats .

After putting on rollers 10 and 5 of the bag 3 on the horn 12 of the packing mashina as wrap; en1; This machine from the horn is filled with cement bag. Making an incomplete turn, the machine automatically drops the bag from the horn onto a conveyor (not shown), if the bag is completely filled with cement to the required weight. Upon further rotation of the packaging machine, the empty horn approaches the device and an empty bag is put on it again. Depending on the different inclusions in the cement grades and the properties of these grades, part of the bags may be filled to the required weight through the horns not for one revolution of the packaging machine, but for two or even three turns. In this case, to automatically pass the horn, i.e., to prevent the bag from being put on by the other bag, the locking device is activated.

The locking device works as follows.

At the moment of occurrence before the device of the horn, taken up with the bag 38, the bag rests with its valve 24 onto the lever 24 (fig. 3), rotates it together with the profile cam 25 around the axis 26. The cam 25 through the roller 30 informs the plunger 31 through the roller 30 D, while the stop 33 (FIGS. 4 and 5) rests on the bar 34 on the lever 14 and does not allow the lever 14 to rotate around the axis 39B in the direction of pressing the movable roller 15 to the next bag 3 and the fixed drive roller 10 to feed this bag on the horn due to the rotation of the rollers.

At the same time, through the pusher 35 of the ball transmission mechanism 19, the lever 14 of the movable roller 15 communicates stroke E (FIG. 5) to press the roller 15 to the bag 3 and the roller 10 to feed the bag to the horn. This move E is compensated by

compressing the spring 36, and the lever 14 remains in place, as the stop 33 rests against it through the bar 34. Thus, part of the device is prevented from overloads and breakdowns by the spring 36.

As the packaging machine rotates,

after the horn with the bag 38 leaves the device’s donning zone and the lever 24 (Fig. 3), this lever returns to its original state with the spring 28.

Thus, simple in design

the locking device allows you to increase the operation of the device and eliminate the emergency situation.
