Description

The invention relates to lifting and transport equipment, namely, stackers for servicing razons of height and frame racks with variable pitch of cells at a height.

The purpose of the invention is to improve the performance characteristics by providing a continuous process of vertical movement.

FIG. 1 shows the stacker, general view; in fig. 2 - the same, side view; in fig. 3 - the position of the carriage and the hoist when the hoist interacts with the vertical guides of the rack; in fig. 4 shows a cross section along the driving and driven sprockets and the expanding disc of the mechanism for vertical movement when they interact with the inner ends of the spring-loaded two-arm levers.

The device body is made integral and divided into a trolley 1 with a horizontal movement mechanism 2 and shortened guides 3 and a lift 4 with a vertical movement mechanism 5, made in the form of closed chain gears 6 and guide rollers 7 mounted on the sides of the vertical mechanism body 8 moving 5 at a distance equal to the horizontal step of the cell. A lifting device 9, a drive 10 and a gearbox 11 are mounted on the elevator 4. The gearbox 11 is kinematically connected with the mechanism 12 of the lifting device and the mechanisms of the vertical 5 and horizontal 2 movements. On the chain links of the closed chain gears 6 of the vertical movement mechanism 5, the supporting clamping mechanisms 13, made in the form of brackets 14 mounted on the chain links 15, are attached, on each base 14 spring-loaded two shoulders 16 are hinged and crosswise mounted. two shoulders 16 are provided with friction jaws 18 and have the ability to press against the shortened guides 3. The expanding discs 19 mounted on the driving 20 and the driven 21 sprockets have the ability to interact with internal shoulders 22 spring-loaded two-arm levers 16. FIG. Figure 3 shows the rack 213 and vertical rails 24.

The device works as follows.

In the initial position, the lift 4 is firmly held on the shortened directions 3 of the trolley 1 with friction jaws 18 on the outer shoulders 17 of the spring-loaded two shoulders 16 mounted on closed chain gears 6. On a command from a computer or from a control panel (not shown) the stacker executes the command to take the load 25 at the initial position. The actuator 10 is turned on and through the gearbox 11 and the mechanism 12 of the load gripping device the load gripping device 9 advances to receive the load 25. Next, the lift 4 moves to the height required to lift the load 25 from the initial position, and the load gripping device 9 returns to the initial position. The command "Put the load in the cell includes a drive 10 and through the gearbox 11 mechanism 2 horizontal

the movement moves the cart 1 to the specified address of the rack 23. After moving to the specified address, cart 1 on the command stops at the specified horizontal address of the rack 23. In this position, the shortened guides fall exactly

under the vertical guides 24 of the rack 23. The drive 10 is turned on and, through the gearbox 11, the rotation is transmitted to the vertical movement mechanism 5. In the upper part of the closed chain gears 6 spring-loaded two-armed levers 16

their inner shoulders 22 come out of interaction with expanding discs 19 and their outer shoulders 17 with friction jaws 18 interact with shortened guides, and in the lower

parts of closed chain gears 6 spring-loaded two shoulders levers 16 with their outer shoulders 17 emerge from interaction with shortened guides, interacting with expanding discs 19 mounted on leading 20 and followers 21

asterisks. The elevator 4 rises, and the guide rollers 7 provide a normal transition from shortened guides to vertical guides 24 of the racking 23. Having stopped at the vertical address, the load gripping mechanism 12 turns on and the load gripping device 9 lays the load 25. Putting the load 25, the load gripping device 9 returns to lift 4. Going to the shorter guides, the stacker is ready for a horizontal shift.
