Belt conveyors 1 of the feeder (see Fig. 6) are driven by a common drum 13. Above the end of each conveyor pushers 14 are placed, the side walls of which are a continuation of the lateral guides 15 with covers 16. In addition, each pusher has a bar 17, perpendicular guides 15. The hubs of all the pushers are freely mounted on the rod 18 and pressed against the stops 19 by the springs 20. The hub of the pusher has a shoulder with teeth 21 against which a fixed toothed fence 22 is mounted on the frame, with the tooth 21 placed against the gaps between the teeth It is time 22. In the initial position, in the gap between the stop 22 and the teeth 21, there is a valve 23, which is a blocking member. The spring 24 presses the rod 18 to the cam 25. Above the end of each conveyor / a signal flag is set 26. Communication between the flag and the locking flap 23 can be effected by electromagnetic or mechanical means. Between the conveyors / transporter nests in the form of forks with curved nodes at right angle teeth formed by the bottoms 27, walls and lateral stops 28. The bottoms are flush with the conveyors 1; the side width stops 28 are positioned against the pushers 14, and the distance between the stops corresponds to the size of the candy. Each nest is provided with a clamp 29 with pressure ends 30 and 31, respectively, lower and upper, freely mounted on the horizontal axis. Iod by the action of the spring 32 is pressed down and in the raised (open) position is held by fixed stops 33. The graver's sockets are attached to the traverse by 3 brackets 34. The rover with vertical rolling pins 35 and straightener 36 forms the graver's vertical frame. The rolling pins slide freely in the guides 3 /, forming a horizontal frame of the graver with the rod 38 and tensioner. On the dronestein 34 there is fixed a copier ski 39. The bar 38 can slide in fixed supports. The spring 40 presses the rod through the lever 41 to the cam 42, telling it to reciprocate in the horizontal direction. The vertical frame of the transporter is supported by the ends of the rollers 35 on the guide 43 under the action of the springs 44. The guide 43 with the levers 41z and the shaft 46 form a pivoting frame pusher actuated by the lever 47 supported on the end cam 48, telling the yoke 3 reciprocating vertical movement. The cams 42 and 48 are mounted on the shaft 49. The feeder is driven from the electric motor 50 through a chain drive with sprockets 51, 52, shaft 53, bevel gears 54 and 55 and shaft 49. The shaft 49 is connected to the shaft 56 by means of a chain gear 56. drive pushers 14. From the shaft 56 through the bevel gears, the drum 13 of the conveyor 1 is driven. At the links of the chain conveyor 2, there are bushings 57 (see Fig. 3), in which rods 58 with springs 59 are seated freely. At the upper end of each stem installed media containing site 60 with slits mi, corresponding E m the fork teeth forming neresadchika socket, the side walls 67 and a protrusion 62, wherein the axis rotatably mounted on the tension plate 63, performs the capture moiety role for holding the blank of wrapping material, and fixing the article in the carrier. The bar is provided with a cantilever pin 64 for engaging with the transporter copier ski 39 and a spring 65 for returning it to its original position and pressing it against the wearer. A pad 66 with gaps between the teeth, the width of which is equal to the width of the platform grooves, adjoins the carrier 60. The comb is mounted on the sleeve 57 of the chain conveyor 2, the sprocket 67 of which is mounted on a vertical shaft 63, which is driven into rotation from the shaft 53 through bevel gears. Tension sprocket 69 is integral with housing 12 of control rotor and rotates freely on fixed axis 70. On the bed under the lower ends of the rods (in place

passing the chain along an asterisk) a copier 71 is fixed, and a copier 72 is fixed at the upper end of the axis 70. The probes 73 are passed through the vertical holes in the housing 12 in the form of stepped rods bearing at the ends of the pad 74 located above the heads of the carriers. Probes 73 are located above all conveyor carriers enveloping sprocket 67.

In the second stage of the probe 73, the flap 75 slides freely against the walls of the housing 12. The tongs and the flap are pressed down by the springs. The rods 76, pressed against the copier 72 by springs 77, are passed through the radial holes in the housing 12. At the 72 ends of the rods 76 removed from the copier, sector cams 78 with stop teeth 79 are fixed. When the damper 76 is at the bottom (see Fig. 3, pos. D ) the tooth of the pie cam 79 is placed with it in the same horizontal plane. If the rod 76 is against the minimum radius of the copier 72, then a gap is formed between the copier and the end of the rod (see Fig. 1, pos. E). In the upper position, the flap is located above the horizontal plane of the placement of the tooth 79 (see Fig. 3, pos. E). Spring 77 presses the rod 76 to the copier 72, both at its maximum and at its minimum radius (see Fig. 1, pos. G. I).

One of the straight sections of the chain conveyor with carriers is located under the feeder (top in Fig. 1), the other is under the device for feeding the wrapping material from the rolls with the cutting mechanism and the wrapping device.

The device for feeding the wrapping material from the rolls with the cutting mechanism into individual blanks consists of roll holders 4 (see Fig. 2) for the spools of the wrapping material, levers 80 with band brakes 8}, a pair of feed rollers 5 and 5 n rotating knives 7. Roller 5 is mounted on a shaft 82 driven by a shaft 53 through an intermediate roller 83 and a chain drive with sprockets and conical shchestren. The roller 6 is mounted on a carriage 84, which sits freely on a fixed axis 85 and is equipped with a spring 86. The roller 6 and the knives 7 are driven from the shaft 82 through gears. In the upper part of the carriage 84, a spring-loaded clamp 87 is fixed, against which the table 88 is mounted. In addition, the carriage is equipped with a pusher 89 interacting with a lever 92, which is freely mounted on the axis 91. The profile of the elongated lever 92 of the shoulder 90 approaches the control radius of the sector cams 78 the rotor.

From the end of the chain conveyor, the sprocket 69 to the beginning of the core section of the lever 92 on the control rotor contains as many sector cams as there are carrier steps on the straight section of the chain conveyor from the control rotor to that position of the carrier, which precedes its alignment with the plane to the wrapper feed. material (see Fig. 2). A stationary cam 93 is mounted in the area of the plane K on the level of the cantilevered finger 64 of the carrier. Behind this feed plane is a clamping device in the form of a ski 94 passing into a patterned brush 9, the profile of which repeats the profile of a copier 95 fixedly mounted under the lower ends rods 58. Behind a device for feeding wrapping material with a cutting mechanism above the chain conveyor 2 there is a device for wrapping sweets - a chain conveyor 8,

on the fingers of the chain links of which, carriers are mounted in the form of a lalock 96 and 97, interconnected by the toothed sectors and stretched by a spring. The grab pitch is equal to the pitch of the carriers. Foot 96 has

shank 98. The speeds of movement of the conveyors 2 and 5 on the straight line are equal.

Tensioning sprocket 99 is loosely mounted on the tensioning axis, on which the copier 100 is fixed. When the shank 98 slides along

likes 96 and 97 are copied (see FIG. 2, pos. L). When the tail comes off the copier, the legs are closed (see Fig. 2, pos. M).

The drive sprocket 101 (see FIG. 5) rotates with the shaft 102 driven in

rotation from shaft 68 through bevel gears. On the shaft 102, rotors 103 are mounted on both sides of the conveyor belt of the wrapping device. These include rotating spindles 104 with twisting tongs 11. The pitch of the tongs on the rotor is equal to the pitch of the candies in the legs 96 and 97 when the chain conveyor 8 sprockets 101.

In the zone corresponding to the section of the lower profile of the copier 95, at the level of the fingers

64, similar to copier 93, mounted copier

105. Further, there is a bend-out consisting of two flat counter-rotating rotors 10 with profiled blades. The upper plane of the rotors coincides with the lower plane of the candy, clamped in the feet 96 and 97. The rotors are mounted on vertical shafts.

106, driven in rotation from the shaft 53 through bevel gears 54 and 107, the transverse shaft 108 and a pair of bevel gears. Behind

The rotors 10 have a fixed ski skirt 109 with a rounded section, concentric to the shaft 102 bordering the candy with its lower part. A tensioning sprocket mounted profile bar 110 with holes for the passage of legs 96 and 97, which ends with a bypass tray 111.

The machine works as follows. Candies from a multi-line production line, for example an enrobing machine, are fed to belt conveyors /, are moved along them all the way into the control flag 26 and fall into the pusher 14 (see Fig. 6 and 7). When the cam 25 rotates, the rod 18; moves 24. At the same time, the pushers,

crushed by springs 20 to stops 19, follow rod 18, shifting the candy from conveyors 1 to the bottom of the 27 nests of the transplant. If on the KaiKOM conveyor the candy doesn’t click on the flag 26, then the A-switch will raise the flap that closes the gaps between the teeth of the fixed stop 22. As a result, the teeth 21 of the pusher 14 will not pass between the teeth of the stop 22, the pusher will remain in the initial position, the rod 18 moved by the spring 24 will move, the stop 19 will move away from the hub of the pusher, the spring 20 will grow. If the candy presses the flag 26, then the flap 23 remains in the lower position, not preventing the pusher from moving, pushing its candy into the slot. In this way, the plank 17 blocks access to the next, to her Candy. In the pusher (Fig. 7, pos. P).

Then, the end cam 48 rotates the shaft 46 with the levers 45 through the lever 47. The firing guide 43 of the rotate 35 with the crossbeam 3 and the sweeper hooks attached to it 35 is lowered. Here, the candies are brought out of the pushers, and the pushers return to their original position. The pressure ends 31 of the clamps 29 descend from the stops 33, and the candies are pressed against the bottoms of the sockets {Fig. 7, pos. Iii)

The slots are lowered into the gaps between the continuously moving carriers of the chain conveyor 2. Simultaneously, the cam 42, pressing the lever 41, moves the rod 38 in the horizontal direction. The guides 37 and, consequently, the traverse 3 move together with the rod. When the carriers moving at a constant speed catch the nests, the speed of the latter in the horizontal direction becomes close to the speed of the carriers.

When the carriers are approaching the sockets, the fingers of the -64 of the slats 63 interact with the ski 39, thereby opening up access to the sockets in the carriers (Fig. 7, pos. IV). The clips 29, the slip bottom ends 30 on the tank walls 61 of the carriers, are opened, releasing the candies in the nests. At the same time, the fingers 64, going out from under the ski 39, release the slats 63, which are closed by the action of the springs 65, limiting the shift of the candies in the carriers (fit. 7, pos. V). Since the speed of the carriers is higher than that of the nests, they overtake them, removing candies from them. The difference in the speeds of nests and carriers is insignificant; therefore, the candies are removed almost without strikes. After the sockets exit the carriers, the clamps 29 close. The nests under the action of the cam 42 receive a speed equal to the speed of the carrier movement, and under the action of the cam 48 they rise by the bottoms above the upper plane of the candy (Fig. 7, pos. VI). After this, the sockets, together with the crossmember 3, return to the initial position (see Fig. 7, pos. VII).

The transfer of candies from all conveyor belts 1 into carriers occurs simultaneously, therefore the number of candies transported per unit of time by a chain conveyor with carriers is equal to the sum of candies accepted at the same time by nests from all conveyor belts. During the movement of the chain conveyor by the number of carrier steps equal to the number of the graver's nests, the nests perform a full cycle: returning to the starting position, receiving candies from the pushers, lowering the carriers into the zone and transferring the candies to them. In this case, the first nest transplants candy to the carrier, following the one that received candy from the last nest during the previous cycle.

The candies installed on carriers by a chain conveyor are supplied under the control

rotor (see Fig. 8, pos. VIII). When the conveyor bears an asterisk 69, the candies are arranged on the carriers coaxially with the probes 73. The rods 58 of the carriers under the action of the copier 71 rise to a level at which the platform 60 of the carrier does not touch the platform 74 of the probe. If there is a candy on the floor, it raises the probe 73 along with the flap 75.

With further rotation of the rotor rods 76 transition t with the maximum radius of the copier

72 at the minimum and under the action of the springs 77 move to the axis 70. When the candy lifts the probe with the flap, then the corresponding stem together with the pie cam 78 moves up to the stop to the minimum radius of the copier 72 (see Fig. 1, pos. G) . In the absence of candy, the sector cam 78 abuts the tooth 79 into the flap 75 and a gap is formed between the cam 72 and the stem (see Fig. 1, pos. E). Copier 71

the stock 55 with the carrier and the candy descends and takes its original position. At the same time, the probe 73 is lowered by the action of the spring, pressing the candy to the carrier pad 60. In this case, the flap 75, raised by the probe, is above the sector cam 78 and rests upon it when the probe is lowered.

Going out from under the control rotor, the carrier of the chain conveyor moves along a straight line section to the device for feeding

wrapping material from the rolls with mechanisms for cutting the material into separate blanks, and the sector cam 78 corresponding to this carrier - to the profile section of the lever 92. If there is candy on the carrier, then

sector cam 78 passes by the lever 92, I will not influence it. In the absence of candy, the sector cam, pushed to a larger radius, pushes the lever 92 at a time when the carrier without candy is from the plane / C of the supply of blanks of wrapping material (see Fig. 2) at a distance of one step.

The lever 92 is held by the cam 78 in the depressed position for the time that the carrier without candy is moved one step. After that, the copier 72, pressing the rods 76, pushes them with the cams 7S to the position of the maximum distance from the axis 70, which leads to the lowering of the flaps 75 under the action of the springs to the initial position.

When the carrier approaches the plane / S (see FIG. 2), the finger 64 interacts with the cam 93, as a result of which the bar

63 is opened, the wrapping material is fed by the rollers 5 and 5 into the gap between the front plane of the carrier and its open bar 63 (see FIG. 8, pos. IX). When the front plane of the carrier coincides with the plane K, the knives cut the workpiece from the tape. Simultaneously copier 93 frees finger

64 and the strap 63 is closed by the action of the spring 65, clamping the workpiece on the carrier. Thereafter, the carrier with the candy and the preform is moved under the ski 94, which bends the wrapper over the top surface of the carrier and the candy.

If there is no candy on the carrier, then when the lever 92 is turned, its shoulder 90, pressing the pusher 89, rotates about the axis 55. The cage 84, compressing the spring 86. In this case, the roller 6 moves away from the roller 5 and the ribbon feed stops, and the clamp 87 slows down the ribbon , pressing it to the table 88. In this case, after the corresponding sector cam 78 leaves the limits of the lever 92, the spring 86 returns the carriage and the lever to its original position and the tape feed is resumed.

With further movement of the chain conveyor, the brushes 58, slippers on the copier 95, raise the carriers with candies and blanks (wrappers) clamped by the bars 63. Brush 9, slippers on the blank, smooths it over the candy, simultaneously fixing the candy in the direction opposite to the movement of the conveyor, its rise beyond the comb 66 (Fig. 8, pos. X).

By the end of the Ascent, the candy, along with the binder, lies between the open legs 96 and 97, which move parallel to the carrier at the same speed. After that, the interaction of the shank 98 with the cam 100 is stopped and the tabs 96 and 97 converge under the action of a spring, clamping the candy with the billet. Then, as a result of the interaction of the finger 64 with the copy 105, the bar 63 opens, releasing the clamped workpiece. The stock-58 with the carrier under the action of the spring 59 is lowered, and its strap is held in the open position by the copier 105. The carriers of the chain conveyor, rounding the drive sprocket 67, return under the transporter, from which candies again fall into them. The candy in the billet forming the semi-tube is moved, clamped by the legs of the chain conveyor 5, to the rotors W. The blades of these rotors are shaped in such a way that they let the leading edge of the semi-tube pass, and its rear edge is bent under the lower edge of the candy (see Fig. 8, pos. Xi). Following this, the leading edge of the half pipe is encountered with the bending ski 109, and this happens even before the longitudinal rotors 10 stop holding the edge that they have tucked in. In this case, the front edge is superimposed on the rear edge, the blades extend beyond the billet and the candy appears in the tube. Upon further movement, the candy in the tube is placed between the twisting tongs 11. During the bending of the chain conveyor sprocket 101, it is stationary relative to the axes of rotation of the shredders 104. At the same time, the twist tongs close, clamp the ends of the tube, and during the passage of the candy half of the rotor's circumference twist it (see FIG. . eight,

pos. Xii).

When the candy is in the up position, the forceps open, releasing the twisted ends of the wrapper and return when the rotors 103 are rotated to the lower position, grasping the ends of the next tube. The candy, clamped in the paws, moves to the tension sprocket 99. The profile strip of the software comes under the candy, and as a result of the interaction of the shank 98 with the copier 100 (Fig. 8).

pos. Ch1P) legs open up and the candy gets into the side tray ///. While holding the copier 100 in the open position, the legs return to the lower position to receive the candy.
