OcTaHOB ka of all three elevators gives a signal to turn on the horizontal movement devices inside the heat-insulated chamber I; the loading and unloading 4 and the overload 5. At the same time, they are moved from the rightmost polysun to the leftmost (Fig L). Reloading device 5 idles, and loading and unloading 4 moves empty

pallets 71 from copier 3 to guides 142, along guides 142 and from guides to the copier 30. When they reach the leftmost position, the unloading lift 29 is unlocked and, under the action of gravitational force, the pallet 71 with the frozen product is lifted on the elevator. The packs 134 are placed on 1 section 35 of the copier, and the pad is lowered into the grooves between the sections. After this, the trans: porter 113 of the unloading mechanism 33 is turned on and the packaging is removed from the machine. The end of the unloading mechanism is a signal to reverse the movement of the horizontal pallet moving devices: the loading and unloading device moves the pallets from the loading elevator to the lifting and lowering elevators to the unloading Loading device 5 at the same time, it does not move the pallet from the lift elevator 2 to the lowering lift 3. This operation ends the full cycle of the apparatus,

Further, a detailed description of the operation of the apparatus is carried out according to the node method. All operations are linked and synchronized in time.

A cover 134 with the product is individually supplied to the cover 124 of the table Ii 2 between the last two pushers 131 of the conveyor 113; after filling one row of packages, the 1I7 electric motor is turned on and, through a reduction gear, 1165 sprockets 118 and 9 9 with a chain 120, rotates a P4 shaft with gears 115, which move the rack bars 128.

When loading the packages, they were installed correctly on the copier 30, the arrows 151 are installed on the plate 124 of the table 112. Their functions are to move apart

10 of the pack 134 at a distance m from each other, corresponding to the placement of the sections 135 of the copier. The movement is carried out one step - distance 1 between the axes of two adjacent shovels. After the conveyor is stopped, its reverse movement occurs: the carriage 122 returns to the initial

position on frame 121, while raising in reverse order

earrings 132 with pushers 131. After the pushers are fully raised and the rollers 133 have reached the upper edges of the slots in the eyes 127, the frame 121 returns to its original position.

There is an accumulation of the second row of packages and the turn 1 of the PZ conveyor is repeated, with the difference that two rows of packages move. Perpendicular movement of the packages is carried out in order to prevent the packages from running over each other, their tilting and jamming in the process of movement. The number of moves depends on the number of series of IDs installed

on-baking packages. It is equal to n -1. After filling the last row of packages, the two tracks of the conveyor 113e are repeated, but the frame continues to move forward.

The front edge of the conveyor 13 presses on the lid cover 34 of the loading window 24, and it is rotated on the hinge ax 36. Transporter 113 - enters the packaging in the open window 24

heat-insulated camera 1 and installs it on section 135 of copier 30, on which pallet 71 stands. On return movement of conveyor 113, first, pushers 131 are raised

by reverse movement of the carriage 122, the frame 121 returns to its original position, while krippku 34 boot window 24,

The closing of the loading window 24 is a signal for starting the next loading stage — raising the pallet 71 on the guides 69 of the loading elevator 28. In this case, the partitions 138 of the pallet 71, which were in par 7

The cracks between sections 135 of copier 30 pass between the packages and lift them by the flanges. Thus, the packages 34 are suspended on a pallet. Lift 28 raises the pallet to the upper level of the device 4.

The horizontal displacement devices and elevators located in the heat-insulated chamber 1 are driven from the drive mechanism 38. After the loading window 24 is closed, the gear motor 40 is turned on. At the same time, the brake clutch 47 is turned on and the drive clutch 45 is turned on. Through the safety clutch 41, the gear 42 the coupling 45, the shaft 49, the gear 43, the coil 51, the shaft 12, the gear 8 and the shaft 13 are transmitted to the gear 9, from which the upper shafts 61 of the conveyors 55 and 56 are driven by shafts 14 and 15 and gears 10 and 11 raising th elevator 2 .. After carrying chains 67 and 68 for sprockets 63 and 64 and sprockets 65, 66 rotate shafts 62 raising the elevator. From shafts 62, sprockets 74, 75 and chains 76 are driven by conveyors 53 and 54 of loading lift 28. Upper shafts of conveyors 57 and 58 of lowering lift 3 are driven from upper shafts of conveyors of lift lift 2 via gearboxes 73. operation of elevators 2,3 and 28 is synchronized.

The movement of the pallets 71 on elevators 2 and 3 is carried out to a height equal to the distance between two adjacent tracks 69-on the elevator. At the end of the movement, the gear motor 40 is disconnected, at the same time the brake clutch 47 is turned on and the drive clutch 45 is turned on.

At the end of the movement of the elevators, the gearmotor 40 is turned on, the brake clutch 48 is simultaneously disconnected and the drive clutch 46 is engaged. Through the safety clutch 41, gearbox 42, clutch 46, shaft 50, gearbox 44, coil 52, shaft 18, gearbox 16, shaft 20s with gears 22, the movement is transmitted to the toothed racks 84 of the loading and unloading device 4, and through the shaft 19, the gearbox 17, the shaft 21 with the gears 23 to the toothed bars 87 of the overload 7 330427 V.

device 5, thus synchronized operation of horizontal movement devices.

Before the movement of the devices for horizontal movement of the frame of both devices, they are in the extreme right position (Fig. 1). those. shifted to the side of the discharge window.

10 The movement of the loading and unloading device 4 begins with the movement of the carriages 78 with toothed racks 84 on the rollers 83 across the frame 77. In this case, the fingers 85, mounted on 15 rebars, run onto the cables 82, mounted on the frame 77, and twist them. The second shoulder ryya-. gi 82 press on pushers 81: pushers 81 mounted from the upper

20, the sides of the frame 77 are lowered and installed in the slots of the frame, and the pushers mounted on the underside are pulled out. After the carriage 78 reaches the stop,

25, the frame 77 begins to move along the rollers 79 to the left, moving the lower pushers 81 to empty pallets 71 from the discharge window to the loading box, from copier 31 to guides 142, along

30 guides 142 and guides 142 to the copier 30. The pushers 81 abut against the edges of the pallets 71 located on the copier 31, on the guides 142 under the lowering 3 and elevator 2 elevators. When moving the loading and unloading device 4, the rear edge of the pallet 71 located on the cam 31 attacks the beveled edge of the sections 135 of the copier 31

40 and the front edge of the pallet 71, located on the guides 142 under the elevator lift 2, runs over the beveled edge of the section 135 of the copier 30 and slides, repeating their configuration,

45 on the surface of the sections of the copier. At the end of the movement of the conveyor; an empty pallet is installed on the copier 30. The upper surface of the frame 137 and the partitions 138 of the pallet

50 71 is located in the same plane with the surface of the sections 135 of the copier, occupying the grooves between the sections 135.

The reloading device 5 is moved when the VII gears 23 interdamer moves with gear rails 87 mounted on frame 86. Frame 86 with gear rails 87 rolls onto rollers 88. At the time of ramming the pusher 91 onto the grippers 98 pusher

rotates on axis 90 and engages clips 96 in an upward position. In the left extreme position of the device, the latches 96 overlap with the copiers 97 and get out of the engagement with the pusher. Under its own weight, the pusher turns on the axis 90 5 returning to the initial position, fixed by chime 92.

When horizontal devices reach the leftmost position, the geared motor stops the brake clutch 48. The reverse of the devices is secured by disengaging the brake muff 48, changing the direction of rotation of the geared motor to the reverse (reverse).

The reverse movement of the loading and unloading device 4 begins with the movement of the carriages 78 to the right on the rollers 83 on the frame 77, and with the fingers 85 on the carriages 78 the levers 82 run: 1 in the opposite direction, the holders 8, located on the lower side of the frame 77, and vshchvig pushers on the upper side of the frame. After the carriage 78 has reached the stop, the frame 77 begins to move to the right along the rollers 78. The pushers 81 on the upper side of the frame move the loaded pallets; from the guides of the loading elevator 28 to the guides of the elevator 2, and from the lowering elevator 3 to the unloading elevator 29

When moving to the right (FIG. I, the reloading device 5, the frame 86 rolls along the rollers 88., the rods 94 of the pusher 91 abut against the pallet 71, which is located on the upper wheel of the elevator lift 2, and move it to the lowering guide lifts 3, the passage grips 98, the pusher 91 deflects them forward on the axes 100. After passing through, with the gripper of the grippers 98, the latter, under the action of the springs 99, return to their original position (ora 101,

In the proposed freezer, a constructive solution is provided for eliminating the example of pallets 71 to guides 69 in the freezing process. With this

np-1 and properties, such as fluoroplastic. In a way, the contact of the pallet with the guides is carried out not over the entire area of the guides, but by points. In this case, freezing is excluded.

However, during operation of the apparatus, such a situation is possible in which the samples of the c on the guides 69 ice on the crust in height exceed the heads of the screws 70 and may freeze the pallet to the guides. The greatest likelihood of a freezing elevator elevator 2 is 2. In this case, on the transshipment device 5, there is an undershot wedge-shaped rail. Its effect is as follows. The pallet, frozen to the guides, resists the pusher 91, and the rods 94 when moving the device 5, compressing the spring 95, are installed in the holes of the pusher 91. The blasting wedge 93 with an angle at the bottom of the bottom of the pallet 5 lifts its edge with a sharp edge. Ice breaks out, pripa on the contact surface and the pallet is released. Thereafter, the resistance of the pallet to movement decreases and under the action of the springs 95 the rods 94 return to their original position.

Thereafter, as the horizontal devices stop in the leftmost position, the unloading elevator 29 lowers, withdrawing the package 134 from the grooves of the pallet, turns on the electric motor 117. The unloading mechanism 33 and drives the conveyor 113 (similarly to the loading mechanism 32). With the raised pushers 131, the conveyor 113 opens the discharge window 25 by turning the hinge 35 on the hinges 37, and stops in the leftmost position above the cam 31. When the conveyor moves backward, the pushers 131 are lowered and the packaging 134 with the frozen product is removed from the heat-insulated contour. In this case, the discharge opening 25 is closed by the cover 35. The removal of the packages from the table 112 is carried out similarly to their accumulation in rows, but in reverse order.

Air coolers 6 and 7, installed at the ends of the apparatus, work in an uninterrupted manner. The fans 105 are turned off only for defrost time. Freezing occurs mainly when the product moves on lift 2 and lowers 3 elevators in the air flow passing through the cargo volume in the gaps formed by pallets 71 with packages 134 and plates 72 on chains elevators.

The fan 105 of the air cooler 6 draws air from the lower evaporative battery 103 through the air duct 107. This ensures the removal of heat and moisture inflow to the air during its interaction with the product. Through the air duct 108, air is injected into the upper evaporative battery, where heat from the fan is removed and air is cooled again.

In the air cooler 7, the air is sucked through the top and injected through the lower evaporator batteries,

The defrosting of the air coolers is carried out in a combined manner.

supplying the coolant vapor to the evaporating batteries and irrigating them outside with warm water. Since the freezing of the snow coat occurs mainly at the air inlet entrance, i.e. In battery 103, the defrost duration is reduced due to the intensive irrigation of sections of this battery. For defrosting the air cooler 7, irrigation is used in exceptional cases. In order to prevent moisture condensation on the parts of the insulated chamber 1, during de-icing, the louvered grilles 109 are closed. The software sprinklers are installed above the sections through which air from the chamber is supplied to the air cooler, i.e. in the air cooler 6 - above the bottom battery, and in the air cooler 7 - above the top. The pallets 111 are installed in the frame 102 of each air cooler, the condensate is drained beyond the limits of the heat-insulated circuit,

The implementation of loading and unloading and reloading devices in the form of frames mounted on rollers inside a thermally insulated casing ensures the rigidity of the structures and maintaining the same temperature of all parts of the devices, which eliminates the temperature deformations of the parts and the proportionality of the connections. This ensures the reliability of the design in operation. The presence of pushers on the upper and lower horizontal surfaces of the frame of the loading and unloading conveyor ensures that the loaded baking trays of the loading device move to the elevator lift, from the lowering lift to the unloading device and empty trays from the unloading device to the loading ; embedding the pushers in the grooves of the frame makes it possible to provide a contactless passage (rolling) of the conveyor frame over (under) the opposites at its reverse (idle) course. This ensures reliability and ease of use.

The installation of a folding pusher with eg locks and stops on the reloading device ensures its free movement at idle, and the installation of a wedge-shaped strap and spring-loaded rods guarantees
