Description

This invention relates to a warehouse, in particular, to automated warehouses. An automated warehouse is known that contains multi-bay cell racks located with a passage in which a transfer carriage is movably mounted with a cargo cart mounted for movement along load-carrying rails fixed inside each cell 1. However, this warehouse requires additional funds to transfer the load carrier to each cell of the rack. An automated warehouse is known that contains multi-bay cell racks arranged with a passage in which a transfer carriage is movably mounted with a cargo cart mounted for movement along load-carrying rails fixed inside each cell, lifted for the transfer and cargo carts and control systems including sensors 2. However, this warehouse is unreliable in operation if it is located in fire-hazardous premises: because NOT a load trolley has an electric drive that is powered from cable The purpose of the present invention is to increase the reliability of the warehouse in fire-hazardous premises. This is achieved by driving the load carriage inertial, containing a flywheel that interacts with the drive of the transfer car and is connected via gears and clutches to the drive wheels, and each clutch is equipped with a switch mechanism connected by means of a flexible member with a corresponding sensor, which is made in the form of a stop rotating in a vertical plane, mounted on a cargo trolley and fitted with a spring-loaded pawl mounted on its tailor with a finger stop and interacting with the rider ohm attached to the trolley, with one end of said flexible body is secured on the palm and the other associated with a mechanism vklyuchetsh bullshit. The clutch engagement mechanism may include a fork mounted by a helix pododiom of the truck zone, a profile cam movably mounted on the same shaft ratchet with a pawl and screw screw to control the clutch fixedly mounted on the shaft, while the fork is connected with a flexible sensor body and with the profile cam interacting with the ratchet dog.

The automated warehouse (figs. I and 2) consists of many brown racks 1, arranged with flat blocks on the sides of the aisle, on each floor of which rail tracks 2 are reinforced. The transfer carriage 3 is moved along this route, lifted by the right one, with a lift 4, located at the beginning of the passage. On the transfer carriage 3, a load is installed in the carriage 5, equipped with a lifting platform, by means of which the removal or installation of the load in the racks is ensured. The trolley 5 has the ability to move from the transfer trolley 3 to the inside of the racks in the form of guides, the upper shelf of which is a support for the load 6. The receiving storage 7 is installed in front of the elevator 4. The elevator 4 and transfer 1 trolley 3 are equipped with electric drives. The drive of the trolley 5 is filled with inertia, which represents a flywheel connected to the drive wheels by a system of gears and clutches with switching mechanisms. An electric motor 8 is installed on the transfer car to accelerate the flywheel 9 and the drive car 10 of the transfer carriage and the electric motor 11 to accelerate the flywheel 12 of the drive 13 of the cargo carriage. The transfer trolley 3 is equipped with current collectors (not shown), with 4 help of which it automatically connects to the electric socket when entering the platform 4 and in the initial position at the receiving drive 7. The acceleration of the flywheel 12 is carried out from the electric motor 11 by means of a V-belt transmission 14 and rubberized roller 15 mounted on a parallelogram lever mechanism 16, equipped with an electromagnet and a spring to control the pressing of roller 15 to the flywheel 12. On the transfer carriage 3 are also placed the control} cargo trolley 5: mechanisms 17 for turning the probes, mechanisms 18 for activating the mechanisms for complex control of the platform of the cargo trolley 5 and its movement and mechanisms 19 for turning the stop bars 20. The truck consists of a frame 21 on which the flywheel of the drive and control mechanisms are located carts and lifting platform. The platform consists of two skids 22 located on the sides of the frame 21 with the possibility of synchronous shifting up or down by means of a lever mechanism (not shown in the drawing) fixed on the cross-bars 23, rigidly connected to the frame 21. On one of the skids there are four mechanisms of integrated control 24 (FIG. 3), which, when interacting with the pusher of the mechanism 18, includes one of four programs for controlling the load trolley. Side slides 23, side rollers 25, groups of sensors interacting with the cargo package, and probes 26 with sensors 27 and 28 are mounted on the traverse to command a speed reduction when the loads are installed in a cell in the right or left rack and when the cart is returned to its original position (not transfer carriage); The group of sensors that control the movement of the cargo carriage and platform lifting in the left direction, enters (Fig. 3): - sensor 29 for giving the command to stop the carriage when cells are loaded; sensor 30 for giving the command to stop the cart when returning it to its original position; a sensor 31 for commanding a reduction in speed when taking a load; - sensor 32 for giving a command to stop the trolley when the load is taken. The group of sensors, each of which controls the movement of the load trolley and the lifting of the gas head in the right direction, includes sensors for the intended purpose corresponding to the first group in order of priority 33, 34, 35, 36.

On the frame 21 (Fig.7) is the drive of the cargo truck. It consists of a flywheel 12 mounted on a vertical shaft 37 (Fig. 7), connected by bevel gears 38 and 39 with central shafts 40 and 41 of the opposite 5 rotation. The central shafts are connected via a hydraulic transmission 42 and 43 to the shaft 44 by means of turn-on sleeves 45 and 46, which provide a change in the direction of rotation of the travel wheels 47 of the load carriage 5. (

On the shaft of the shaft 44, there is a brake clutch 48, which provides braking for the trolley.

Shaft 44 is connected to shaft 49 through either a cylindrical gear 50 or through. two-sided, five-gear transmissions 51 and 52 through a two-way clutch 53, which enables the main speed to be turned on via gear 50 and micro-speeds through gears 51 and 52. Shaft 49 is connected to shaft 55, 20 on which the running wheels 47 are located. To increase the grip of the trolley with the guides, the shaft 55 is connected to the shaft 56, on which the driving wheels 47 are also located, with a chain drive 57.15

The central shaft 41 is connected via a cylindrical gear 58 to the shaft 59 by means of an actuating clutch 60, which enables the lifting platform mechanism to be activated. .

On the shaft 59 are placed: a brake clutch 61, which provides for the platform to stop and fix in the lower or upper position, and the mechanisms for controlling the platform 62, 63 and 64.

The mechanism 62 provides a platform stop at the extreme positions.

The mechanism 63 provides for switching on sensors 28 and 34 and driving the trolley to return it to its original position from the left direction of the 40 track.

The mechanism 64 enables sensors 27, 30 and the trolley drive to be turned on to return it to its original position from the right direction.

The shaft 59 through a cylindrical gear 65 45 is connected to the shaft 66, at the ends of which crank mechanisms 67 are installed, by means of which the sliders 22..50 are raised and lowered through lever mechanisms (not shown in the drawing).

Each of the sleeves 45, 46, 48, 53, 60, and 61 is equipped with an engagement mechanism (Fig. 8). It consists of a plug 68 connected on the one hand to the movable part of the coupling 69 and on the other, with the help of the leash 70 and roller 71, to the 55th cam 72. The cam 72 through the spring-loaded dog 73, mounted on its flange, can be in engagement with the ratchet 74, mounted on the control shaft 75, provided that the roller 76 of the coaxial 73 deprives of the support of the flat cam 77, the hub of which is freely supported on the shaft 75. On the hub of the cam 77 symmetrically arranged at an angle of 180 for the stst1, on which generators are mounted restrictive shtyfty 78, both Squeezing the cam 72 by 180 ° with one switch on.

The cam 77 is associated with a spring-loaded plug 79, telling it to move along the axis of the shaft 75 when its opposite end interacts with a spring-loaded stop 80 located on the axis 81 in the groove of the rod 82. that when moving to the left, the stop 80 is fixed by the back wall of the groove, and when moving in the opposite direction, it turns freely around the axis 81 as it passes over the ends of the plug 79.

The rod 82 is connected to the cable 83, which transmits the displacement of the sensor to the rod, which moves freely in the side cheeks of the housing 84. The end of the cable is fixed on the lever 85, deflected under the action of the spring 86 and imparting tension to the cable. In the housing 84, there must be as many cables and rods with stops as the sensors must transmit to the forks 79 and 68. The control shaft 75 is coupled to the transmission 87 with the centrifugal shaft 40.

The sensor 27, which interacts with the cargo package (Fig. 9), is a stop 88, which rotates from interacting with the load around the axis 89 fixed on the bracket 90. The stop 88 is connected to the control roller via a spring loaded dog 91 by means of a groove with a lever 92 also pivoting about axis 89. To the end of lever 92, a cable 83 is attached connecting the support 88 to the rod 82.

Stop 88 has two fixed positions. Fixation is realized by means of a spring 93, which, unclenching, in one case deflects the stop 88 up until the axis 94 is pressed against the kronilein 90 (in this case, the spring axis passes below the center of the axis of the turn of the stop) down until pressed to the axis with a rubber damper 95 (in this case, the spring axis passes above the center of rotation of the stop).

On axis 94, cable 96 is reinforced, by means of which movement of the stop 88 is transmitted, leading it to the operating position, with the sensor becoming enabled.

The clutch engagement mechanism - the fork 79 is transmitted commands by moving the cables from the fur {shm 62, 63, 64 of the lifting platform mounted on the shaft 59.

They are made of an eccentric 97 (FIG. 10), interacting with a lever 9S, on a pile

the cable 99 is fixed, which transmits movement either to the plug 79 of the clutch engagement mechanism, or to the stop 88 through the cable 96.

Eccentric 97 through spring-loaded dog 100, mounted on its flange,. may be in engagement with the ratchet 101 reinforced on the shaft 59, provided that the roller 102 of the dog 100 loses the support of the cam 103, the hub of which is loosely supported on the shaft 59. On the hub of the cam 10.3 there is one protrusion on which the limiting pin 104 is installed, which provides turning the eccentric 97 by one turn with one switch on, and the shaft 66 will turn half a turn (either the platform is raised or lowered).

The cam 103 is connected with a spring-loaded plug 105, which tells it to move along the axis of view 59 when the opposite end of the end interacts with the spring-loaded stop 106. placed on the axis 107 in the groove of the rod 108 so that when moved to the left, the stop 106 is fixed by the back wall of the groove, and when moving in the opposite direction freely, it rotates around the axis 107 as it passes over the end of the fork 105.

The rod 108 is connected to a cable 109 that transmits the displacement from the complex control mechanism to the rod 108, which freely moves in the side cheeks of the housing 110. The end of the cable is fixed on the lever 111, which is deflected under the action of the spring 112 (Fig. 7) and tends to tension the cable. In the housing 110 there are four cables and rods with an Mii, transmitting the movement to the plug 105 from the four mechanisms of the integrated control.

Mechanisms of comlex control of sensors and mechanisms. The cargo carriage (Fig. II, 12) interacts with the push rods of the transfer carriage. The mechanism consists of two rollers 113 arranged one below the other and secured in brackets 114. Grooves of different diameters are machined on the rollers, and the cables 115 and 116 are laid and fixed.

The cable 115 transmits movement through the cable 83 to the clutch coupling mechanism 79 (Fig. 8), and the cable 116 through the cable 109 to the fork 105 of the lifting platform control mechanism (Fig. 10). The diameters of the grooves provide the necessary movement of the cables at the same time and the same angle of rotation of the rollers.

Sleeves 117 are also placed on the edge of the rollers, also with a groove for laying and fastening the cables, connected to the roller by means of a sector groove on the pin 118, which allow the pallet 113 to return to its original position under the action of the helical spring without the sleeve 117 returning. The shaft 117 is also provided with spiral springs 120 , returning the sleeves to the initial position and providing the necessary tension of the cables 121, which transmit the movement to the stops 88 through the cable 96.

The roller 113 in the middle part has a fork in which roller 122 is fixed on the axis 123.

The interaction of the pusher 124 of the mechanism 18 mounted on the carriage 3 with the roller 113 is guided through the roller 122. The distance between the axes of the rollers 113 is equal to the height of the lifting of the slides 22, in the result that in the lower position of the slider the plunger interacts with the upper roller, top position - with the bottom.

On the transfer carriage, there are two mechanisms 18 with pushers 124, including either a left-hand block of complex control mechanisms, or a right one.

The operation of the warehouse is as follows.

The automated warehouse runs four programs:

-Putting cargo in the left rack;

- putting the load in the right rack;

-vzie cargo from the left rack;

-vzie cargo from the right rack. Description of the operation of the lift 4

and the transfer carriage 3 is not produced, since it is not the subject of the present invention.

In the initial position, the transfer carriage 3 is located on the rail tracks of the boot drives 7, while its current collectors are in contact with the trolls and the flywheel 9 accelerates from the electric motor 8 and the flywheel 12 accelerates from the electric motor 11 through the V-belt drive 14 and mounted on a parallelogram lever mechanism 16 a roller 15 which is pressed against the flywheel 12 by an electromagnet.

In the initial position, the load carriage 5 is located on the transfer carriage 3. At the end of the first position, all sensors are disconnected, and the clutch brakes are turned on.

Claims (2)

After switching on the desired program, for example, taking the load from the left rack, the automation unit according to the address provides control of the transfer trolley 3 and the lift 4; at the same time, the transfer carriage 3 enters the lift 4. The lifting to the predetermined tusk takes place, and the flywheels accelerate. After the rail tracks of the elevator with the rail tracks 2 racks 1, the transfer car enters the passage of the rack and follows to the specified cell. After docking the transfer carriage guides with the guides of the rack 1, the mechanisms 17 turn on the probes 26, the sensor mounted on the probe does not work, the left side mechanism 18, the pusher of which interacts with the upper roller 113 of the integrated control mechanism, and mechanism 19 the right side of the retracting stop bar 20. The integrated control mechanism incorporates the movement of the trolley and the lifting of its haatform, includes sensors 31 and 32, control mechanisms of the lifting platform 62 and 63 and coupling 46 and 48 of the trolley 5, which simultaneously disconnects the brake of the trolley and activates the drive of the traveling wheels 47. Through the gear 50, activated by the clutch 53, in the initial position of the trolley 5, it moves at the main speed. The inclusion of sensors. 31 and 32 is produced by rotating the roller FROM from the interaction with the pusher 124 of the mechanism 18, while through the puff 118 the sleeves 117, turn, in the grooves of which the cables 121 are transferred and reinforced, transmitting the movement of the cables 96 fixed to the axles 94, which, in their turn, brings the stops 88 to the operating, position. The mechanisms 62 and 63 of controlling the lifting platform are turned on by transferring the movement of the cable 116 through the cable 109 to the fork 105 of the mechanism, as a result of which the cam 103 moves along the axis of the shaft 59, the roller 102 loses its support and the dog 100 engages the ratchet 101. most subsequent cycle. Couplings 46 and 48 are engaged by transmitting the movement of the cable 115 through the cable 83 to the plug 79 of the engaging mechanism (Fig. 8), as a result of which the cam 77 moves along the axis of the roll 75. In this case, the roller TB loses the support and the dog 73 engages with the rotating ratchet 74, the screw cam 72 rotates, moving the leash 70 with the roller 71 and the fork 68 connected to under the living part of the coupling 69. The trolley 5 is displaced until the sensor 31 interacts with the load package 6, resulting in a rotation stop 88 around axis 94 .. Under the action of the spring 93, the stop 88 takes a fixed position, resting the axis 94 against the bracket 90. At the same time, the stop 88 rotates the lever 92 around the axis 89. Turning the lever 92 tells the movement of the cable 83, which through the stop 80 of the rod 82 of the coupling mechanisms 74 ..10 (Fig. 8) rotates the fork 79, telling the movement of the cam 77 along the axis of the roll 75. In this case, the roller 76 of the dog 73 loses its support and the dog 73 engages with the rotating ratchet ohm 74, the screw cam 72 rotates until the roller 76, hitting the opposite lip of the cam 77 , does not bring out the dog 73 and does not stop at the restrictive pin 78. At the end of the turn of the lever 92, the control roller of the dog 91 rolls on the stool 90 and removes the dog 91 from engagement with the lever 92, while under the tension of the tension of the cable 83 the lever 92 returns to its original position. The rod 82 moves with the cable 83 in the opposite direction, while the stop 80, turning around the axis 81, passes over the end of the VSHKI 79 and also the initial position. The cam 77 is moved until the stop VO is in the sheaton with the fork 79. With further movement of the stop 80 it is disengaged from the fork 79, as a result of which it returns to its initial position under the action of ifiy KH they move the cam 77 76. The rotation of the leash 70 with the roller 7 and the fork 68 connected to the movable part of the coupling 69 takes place from the rotation of the Wi-Fi cam 72, while 1troi: there will be a disconnection of the coupling disks 53, which disconnect the G1ersdach 50, and the clutch of the disks of the same coupling, including two steps transfer 51 and 52, reducing the speed of movement of the trolley to fine-tuning. Then, the trojan 1ET interaction of the sensor 32 with the same package of cargo 6, as a result of which the following occur: those: ice operads and in the same sequence as with the credits of the sensor31. From the sensor 32 prog.ZoZoZhet clutch brake discs 48, razb.yk; 1nee disks of the coupling 53, disabling the two-speed gear} 51 and 52, and scattering the disks of the same clutch, including transmission 50, clutch of the clutch discs YO, including the platform lifting mechanism transmissions 58 and 65 and the opening of the discs of the brake coupling 61, which releases the drive for lifting the platform. As a result of switching on the mechanism, the shaft 59 begins to rotate with the ratchets 101, transmitting the rotation through co6atu y 100 m to the centric 97. The eccentric 97 rotates until the roller 102, running over the protrusion of the cam 103, does not unlatch the dog 100 and stop at the restrictive pin 104. One mouth will occur, at the end of which, under the action of the eccentric 97, the lever 98 will inform the movement of the cable 99 of the mechanism 62 transferred to the rod 82, which will turn the plug 79 through the stop 80 of the clutch engaging mechanism, resulting in opening of the discs, brake coupling 48, opening the clutch discs 60 and the clutch of the brake clutch discs 61. In this case, the lifting platform will stop in the upper position, and take off the load package from the shelves of the rack 1. Moving the cables 99 of the mechanism 63 is transmitted through the rod 82 to the support mechanism 80 plugs 79, as a result of which clutch discs 45 will clutch and transferred to cables 96 fixed on axles 94 (Fig.9), which in turn will push the stops 88 of the dates 34 and .28 to the operating position. In this case, the trolley 5 will start to move in the opposite direction at the main speed with the sensors turned on, which are necessary for stopping it in the initial position. When the sensor 28 interacts with the stop bar 20, the clutch discs 53 are disconnected, disengaging the gear 50 and clutching the discs of the same clutch, including a two-stage gear 51 and 52, thus reducing the speed of the load carriage to dope. When the sensor 34 interacts with the stop bar 20, clutch discs 48 clutch, clutch disc 45 opening discs and clutch disc 53 uncoupling discs, disabling the two-stage 5 gear 51 and 52, and clutch discs of the same clutch, including gear 50, come in. After the load trolley 5 stops, the initial position is turned on mechanism 19, unfolding the stop bar 20 and mechanisms 17, turning the probes to the initial position. After that, the drive 10 of the transfer car 3 is turned on, returning it to its original position on the elevator, where the automatic connection to the power supply and acceleration of the flywheels 9 and 12 are made. When the load is installed in the rack cell, the shu is also turned by mechanism 17 and sensor 27 or probe 28 is turned on. When approaching the previously installed package, the sensor 27 or 28 interacts with this package, thereby reducing the speed of movement of the cargo carriage 5. Then one of the sensors 30-31 or 34-35, 12 interacts with the package 6, after which the carriage 5 stops and turns on lifting drive through the clutch 60 of the trolley 5. The cargo package is removed from the rack and the trolley 5 returns to its original position on the transfer trolley 3. Invention 1.
