The invention relates to equipment for the mechanization of loading and unloading operations, namely, devices for stacking products in a package and single-piece delivery of products from the package.

The purpose of the invention is higher productivity.

FIG. 1 shows the device, a general view; in fig. 2 - the same, front view; in fig. 3 - kinematic diagram of the device; in fig. 4 - drive mechanisms of the device; in fig. 5 shows section A-A in FIG. four; FIG. 6 is a section BB in FIG. four; in fig. 7 is a section bb of FIG. four.

A device for stacking products in a package and piece-by-piece products from a package contains a frame 1 with a chain conveyor 2 mounted on it, which can be rotated 180 around a drive shaft, on which parallel chains a scraper 3 is installed. 4. Under the horizontal casing), the lift-and-bridging mechanism is installed, made in the form of two vertical conveyors 5, on opposite branches of which the shelves 6 are horizontally fixed, for the pallet 7. Conveyors 2 and 5 have a common od comprising the motor 8, the sleeve 9 and the worm gear 10 having two output ends of the shafts 11 and 12, one end of the shaft 11 which via a conical transmission 13

At the same time, the pin 34 is displaced into the adjacent parallel groove of the bushing, so that the displacement and interaction of the cam 39 with the cranks 21 and 23 at the exit of the interplay of the disks 25 and 40 are heatsink. from the package, the vertical conveyors are lifted when the crank 21 interacts by singing with the cam 39, and lowering when interacting with the cam 39 of the cranks cranks 21 and 23, for which the sleeve interacts with another pair of op with the pin 35. 7 ill.

drives the horizontal conveyors 2, and the second 12 - through the transmission mechanism vertical conveyors 5.

5 The transfer mechanism includes a Maltese gear 14, a gear cylindrical gear, the changeable gears 15 and 16 of which allow the optimum step size of the conveyors 5 to be selected, and the clutch 17. The movement of the vertical conveyors 5 is transmitted through bevel gears 18 and 19 and the intermediate shaft 20.

Maltese Mechanism 14

two links: master and slave. The drive link contains a crank with a pin 21, rigidly mounted on the shaft 22 and 12 and a crimp pin 23 with a pin, fixed on the sleeve 24 mounted with the possibility of axial movement. The sleeve 24 has a locking disk with a gap 25 and is spring-loaded on both sides by springs 26 and 27, and four ring parallel grooves 28-3 are made on the surface of the sleeve 24. Adjacent grooves 28 and 29, 30 and 31 are pairwise C (i.e., are dinnee to each other by oblique grooves 32 and 33, and mutually (5, act with one of the twin pins 34 and 35.

package, and in the IT position corresponding to the mode of the piece-by-piece delivery of products from the package. The oblique grooves 32 and 33 are located at an angle to the adjacent grooves 28 and 29, 30 and 31 and are directed in the direction corresponding to the direction of rotation of the drive shaft 22.

The follower link contains a shaft 38 with two IQ cam 39 rigidly mounted on it, made in the form of a Maltese cross, and a locking disk 40. The latter is made with four notches 4 1 and serves for fixing the driven shaft 38 when the crank is idling 15 21. The notches 41 of the disc 40 is made concentrically to the outer surface of the disk 25, and the notch 42 of the disk 25 is concentric to the outer surface of the disk 40. Cutting out 42 contributes to the rotation of the home motor of the shaft 38 at the time of the interaction of the crank pin 43 43 and the cam 39.

On the follower link shaft 38, a pinion gear 15 of a cylindrical 25 gear is mounted, which, paired with the pinion gear 16, is selected depending on the height of the product layer and determines the size of the step of lowering or raising the conveyor 5.30

The device works as follows.

When placing the products in the package in the initial position, the scraper 3 occupies the leftmost position, the pallet is located in the extreme upper position, the products are laid on the roller table 4, and the lever 36 is in the IB position, this moment the crank 21 is in the uncoupled position 39, and about the pin 34 placed in groove 28.

When the drive is switched on the working stroke, the scraper 3 moves to the lower branches of the conveyor 2, ensuring the transportation of the product layer along the roller table 45, the conveyor 2 is installed 4 and placed on the pallet 7. At the same time, ticking by turning the crank 21 turns-270. The same angle is turned by cranks 23 and disc 25, the outer surface of which slides 50 along cutout 41 of disc 40, thereby fixing it. Due to the direction of the transition groove 32 in the direction corresponding to the rotation of the shaft

35

When the nepexo / ic of the scraper 3 on the branch of the conveyor 2 degrades the product layer onto the pallet, this moment the crank 21 enters the clutch with the cam 39 and turns it through 90. At the same time, the crank is rotated at this angle, with the surface of the disk 40 ck along the notch 42 of the disk 25.

The rotation of the cam 39 ensures the rotation of the shaft 38, as a result of the gear 15 and 16 through the couplings, they lower the needles on the honeycomb 6 with the don 7 laid on it.

After the filling of the pallet 7 6, the impact on the final cutter (not shown) is disconnected after which it is suspended by any of the loading points.

The electric motor 8 after the ci of the new pallet is switched on in a conventional mode.

When the shaft 22 is rotated opposite the arrow, the pin 34, the edge of the oblique groove 32, fits towards it, under the action of the gum 27 moves into the grooves 2 with the working position of the crooked curve 23. At the same time, the cranks 23 move to the left and interact with the cam 39, which are used by cranks 21 and 23, in the pitch of which it is not rotated, and therefore the stepwise raising of the pallet 7 is the starting position, in which the limit switch (not engaged) ensures that the electric motor 8 is turned on in the operating mode.

The device can be used for single delivery of the product package. For this horizontal

With the nepexo / ic of the scraper 3 on the upper branches of the conveyor 2, the product layer is laid on the pallet 7. At this point, the crank 21 engages with the cam 39 and turns it through 90. At the same time, cranks 23 are rotated at the same angle, with the surface of the disk 40 sliding along the notch 42 of the disk 25.

The rotation of the Cam 39 provides rotation of the shaft 38, in which the gears 15 and 16 through the coupling 17 provide lowering to the desired height of the shelves 6 with the pallet 7 laid on them.

After filling up the pallet 7 of the shelf 6, by acting on a limit switch (not shown), the electrolysis is turned off and the pallet 7 is removed by any of the loading means.

The motor 8 after the installation of the new pallet is turned on in the reverse mode.

When the shaft 22 rotates counterclockwise, the pin 34 moves to the upper edge of the oblique groove 32, due to its direction, moves to the grooves 29 under the action of the spring 27 and locks the working position of the curved bolts 23. At the same time, the cranks 23 move to the left and interact with the cam 39 cranks 21 and 23 interact with, as a result of which it is continuously rotated and, consequently, the stepless raising of the pallet 7 to the initial position, at which the upper limit switch (not shown) ensures that the elec The motor 8 is in operation.

The device can be used for single delivery of products from the package. For this horizontal

For the stepless lowering of the empty pallet, the electric motor 8 is switched on in an operating mode in which the pin 35 under the action of the rod 26 moves through the oblique groove 33 into the groove 31, fixing the non-working position relative to the cam 39.
