Description

The invention relates to the stacking of products, mainly fragile and thin, and can be used in enterprises of the electronics industry for laying thin, fragile, unbaked billets of ceramic capacitors into containers for carrying out group technological processes, mainly roasting, as well as during packaging. A device is known for laying fragile products into a container consisting of conveyors for feeding products and containers, a mechanism for forming a layer of products and a mechanism for transferring a layer of products into a container made in the form of a carriage mounted with the possibility of horizontal reciprocating movement and having a lifting and lowering vacuum. -grip 1. A disadvantage of this device is that a vacuum-grip, dropped by its own weight, damages fragile, thin ceramic products. The closest technical solution to the present invention is a device for placing hops products in a container containing a feeder with a level-keeping mechanism, a vacuum suction device installed with the possibility of horizontal and vertical movement, and a table for containers 2. A disadvantage of this device is the impossibility of providing stable oriented layered layering of thin brittle unfired ceramics fed to the feeder with sinkholes, since during the formation of a group of plate columns in the feeder, Lastin adjacent columns, when the plunger is slid, nalezayut each other. In the process of subsequent layering of plates into the container using a group of pneumatic grip plates of adjacent columns overlap each other, which leads to their curvature during the subsequent firing and marriage products. Moreover, due to the thickness tolerance of the products, as the products are removed from the feeder, the levels of adjacent product columns are in different planes, which leads to unstable operation of the group pneumatic grip. The purpose of the invention is to provide layer-by-layer stacking of fragile products supplied to the feeder in piles. The goal is achieved by the fact that, in a device for placing fragile products into a container containing a feeder with a product level support mechanism, a vacuum suction device installed with the possibility of horizontal and vertical movement, and a table for the container, the feeder is made in the form of a multi-section cassette includes spring-loaded pins installed with the possibility of vertical movement in the cassette sections, and horizontal plates with holes to accommodate the lower ends of the pins, one of the plates mounted with the possibility of horizontal movement and provided with fixers of rods fixed on it, and the table for the container is equipped with a vertical drive. displacement associated with the leveling mechanism and the suction cup via a sensor. FIG. 1 shows the kinematic diagram of the device; in fig. 2 - feeder; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a diagram of switching on the drive of the feeder. The device consists of a vacuum suction device 1 (Fig. 1), mounted on a brush 2, a vertical movement actuator of a vacuum suction device made in the form of a two-arm lever 3 rotatable in the vertical plane and interacting with a cam 4 mounted on a shaft 5 driven by a motor 6 through the gear 7. On the shaft 5 there is also installed a spatial cam 8, interacting with the brush 2 of the vacuum suction 1 by means of a lever 9 and a pinion gear 10. The feeder is made in the form of a multisection cassette 11, in the form of Dah which is located shtochki 12. In addition, the feeder contains plates 13 and 14. In the upper plate 13 (Fig. 2) installed sleeve 15, which serves as guides for the rods 12, spring loaded 16. The bottom plate 14 contains clamps 17, fixing the rods 12 under the action of the springs 18. The plate 14 is mounted. with the possibility of horizontal movement in the guide plates 13. The feeder body 19 (Fig. 3) contains the guides 20. The plate 13 contains slides 21 moving along the guides 20. The sliders 21 contain rollers 22, mounted on axle 23 with the possibility of interaction and a cam mechanism 24 to maintain the level established by the shaft 25. The shaft 25 receives rotation from elektrodaigatel 26 via a gear 27 (FIG. I). In addition, the leveling mechanism contains a pusher 28 (Fig. 2) mounted in a guide sleeve 29 mounted on the feeder housing 19, a lever 30 with a roller 31. The lever 30 is installed with the possibility of swing under the action of an electromagnet 32 and springs 33 in the bracket 34 mounted on the housing 19 of the feeder. The pusher 28 interacts with the bottom plate 14 by means of a roller 35 mounted on the bottom plate 14. The receiving container 36 for the container (Fig. 1) is mounted on the rod 37 mounted in the guides 38. The rod 37 is installed with the possibility of interaction with the cam 39 mounted on shaft 40,

receiving rotation from the electric motor 41 of the type RD,

In addition, the device is equipped with a powder mechanism 42 driven by an electric vibrator and a sensor system 43-50, and the vacuum suction device 1 is equipped with a stop 51 interacting with sensor 43 by means of a flag 52 mounted on lever 53. Sensors 44-50 interact with flags 54-60 mounted on the shafts 5, 25 and 40. The suction cup 1 (Fig. 4) is equipped with spring-loaded springs 61 with suction cups 62, one of which is combined with the stop 51.

The device works as follows: Fragile ceramic plate blanks 63 stacked in stacks in a multisection cassette 11 (Fig. 1) are transferred to a stacking operation in a container mounted on a container table 36 (Figs. 1 and 3).

When the electric motor 6 is turned on through the gear train 7, the rotation is transmitted to the shaft 5. Under the action of the cam 4, the lever 3 rotates in a vertical plane, the vacuum pump 1 together with the stem 2 descends until it touches the suckers

62 blanks 63 (fig. 1-3) When the suction cup 1 is lowered into the lower position, the flag 54 interacts with the proximity sensor 44 and the electromagnet 32 is turned on using an electronic control circuit (FIGS. 1 and 2), which interacts with the lever 30 and roller 31 pusher 28 mounted

in the guide sleeve 29. The pusher 28, interacting with the roller 35 mounted on the bottom plate 14, overcomes the action of the springs 18 and retracts the plate 14 together with the fasteners 17 fixed on it. In doing so, the retainers 17 release the rods 12, which under the action of the springs 16 raise billet bars 63 before contact with suction cups 62 and thereby align the top level of the billet layer

63 in a multiple cassette 11.

When the electromagnet 32 is turned on, the plate 14 under the action of the springs 18 returns to its original position, while the latches 17 fix the rods 12 (Fig. 2). After leveling the upper layer of the blanks 63 in the multi-section cassette And the suction cup 1 (Fig. 1) with the layer of blanks 63 rises and using a rack and pinion gear 10, driven from the lever 9 and the spatial cam 8, rotates together with the brush 2 to the container table 36, lowered until the layer of the blanks 63 contacts the container. At the same time, the flag 55 interacts with the contactless sensor 45, which switches off the vacuum with the help of an electronic control circuit, the layer of blanks 63 remains in the container, and the suction cup 1 returns to the multi-compartment cassette 11 and lowers behind the next layer of blanks 63.

When the suction cup 1 is lowered, the interaction of the flag 54 with the sensor 44 by means of an electronic control circuit activates the filling mechanism 42, which pours the powder onto the layer of blanks 63 packed in the container.

The electromagnet 32 is switched on each time before laying the first layer of blanks 63 in the next container and after replacing the empty multi-section cassette 11 with the filled blanks 63. The electromagnet 32 is switched on at a certain moment by an electronic control circuit.

In the process of placing the blanks 63 into the container, their level in the cassette 11 is lowered. Maintaining a constant upper level of the blanks 63 in the multi-section cassette 11 is carried out by periodically raising the bars of the blanks 63 with the rods 12. This happens as follows.

During operation of the device, the lower level L (Fig. 4) of the suction cup 1 is always in the same plane, and the lower level h of the suction cups 62, as the blanks 63 are removed from the cassette 11, is lowered under the action of the springs 61 and at some point an interaction of the stop 51 occurs, combined with one of the suckers 62, with the lever 53. In this case, the flag 52 interacts with a contactless sensor 43, when triggered, the electric motor 26 is turned on. When the electric motor 26 is switched on (FIG. 1), rotation through the gear train 27 is transmitted to the shaft

25 with the cams 24 mounted thereon. The cams 24 interact with the rollers 22 of the sliders 21 attached to the top plate 13 and moving in the guides 20 of the feeder body 19, resulting in the plate 13 together with the rods 12 and the bottom plate 14 installed with clamps 17 The rods 12 are moved upwards, raising the columns of the blanks 63 in the multisection cassette 11.

Simultaneously with the activation of the electric motor 26, the motor 41 of the RD type 41 is activated, which drives the shaft 40 with the cam 39. When the cam 39 rotates, the table 36 for the container, which is mounted on the rod 37, is lowered (under its own weight).

The amount of lift of the billet posts 63 in the cassette 11 to simultaneously lower the table 36 for tare by the same amount is determined by the time of engine operation.

26 and 6 and is controlled by an electronic control circuit. The interconnection of raising the bars of the blanks 63 and simultaneously lowering the table 36 for the container

with the layers of blanks 63 stacked in it, the suction cup 1 ensures stable operation when gripping blanks 63 from the multisection cassette 11 and smooth, unstressed laying of the layer of blanks 63 into the container. After stacking a specified number of layers of blanks 63 into the container of suction cup 1, it automatically (using an electronic control circuit) stops in the upper position above the container when the proximity sensor 46 triggers from interacting with the flag 56. At the same time, the table drive motor 36 is activated by a signal from the sensor 46 for the container, returning the table 36 to the upper position and stopping in the upper position of the table 36 when the proximity sensor 50 is triggered by the interaction of the flag 60 with it. iodically, the columns of the blanks 63 are raised by means of rods 12 from the sockets of the multisection cassette 11. At the same time, the springs 16 are elongated due to their periodic release by retraction of the bottom plate 14 with clamps 17. When the plate 13 approaches with the rods 12 to the upper position, the sensor 47 from interacting with the flag 57 and turning on the electromagnet 32 and the motor 26. Under the action of the electromagnet 32 (Fig. 1 and 2) through the lever 30 with the roller 31, the pusher 28, interacting with the roller 35, pushes the bottom plate 14, the latches 17 release the pieces ki 12, which under the action of the springs 16 bear against shoulders in the bottom of the I.S. cassette 11. The cams 24 interacting with rollers 22 of slides 21, plate 13 and raised. 14 to the highest position. When this occurs, the springs 16 are compressed. At the extreme upper position of the plates 13 and 14, the sensor 48 is coupled from interacting with the flag 58, the electromagnet 32 is turned off by means of an electronic control circuit, and the plate 14 together with the latches 17 is returned to its original position by the action of the springs 18 rods 12 clamps 17. The engine 26 continues to rotate the shaft 25 with the cams 24 in the same direction. The plates 13 and 14, together with the rods 12, interact through the slides 21 and the rollers 22 with the cams 24, under the action of their own weight are moved to the lower position. In the lowest position when the flag 59 interacts with the proximity sensor 49, the signal from the sensor 49 causes the motor 26 to stop. Thus, the mechanism for maintaining the level of the blanks 63 in the multi-compartment cassette 11 is prepared for operation with a new multi-compartment cassette 11. The empty multi-compartment cassette 11 is replaced with a new one filled with the blanks 63, and the stacking cycle is repeated. The execution of the feeder in the form of a multi-compartment cassette facilitates a clear orientation of the Tock plate blanks at the positions of the gripper from the feeder by means of multi-position pneumatic gripping and packing into the container. The implementation of a level support mechanism in the form of spring-loaded rods installed with the possibility of vertical movement in cassette sections and placed in plate holes, one of which is equipped with rod locks, and also providing a table for container with a vertical movement mechanism associated with a level supporting mechanism and vacuum suction through the sensor, provide a stable, smooth and unstressed vacuum suction, which is of great importance when transferring a layer of plates from the feeder, made in the form of m ogosektsionnoy stacked cassettes therein columns thin, fragile, have a certain thickness tolerance, plates and packing it into a container for Nachod schuyus table. The automatic mode of operation of the proposed device is provided by means of sensors and an electronic control circuit.
