Description

(54) DEVICE FOR SUBMITTING PLATES

one

The invention relates to the construction, in particular, to the stone processing industry and is intended as ancillary equipment for the mass production of cladding products in the form of flat plates of natural and artificial 5 stone.

A device for loading plates onto a transport body is known, which provides continuous and automatic feeding of products from packages, including a packaged feeder mounted on a bed, performed in the form of a fixed cassette with side cheeks, in the guide windows of which the sliders of the auxiliary package pushers mounted are mounted on vertical axes fixed in the tides of the sliders, and the main package pusher is mounted on the hydraulic cylinder rod mounted on the base of the cartridge, and intermediate accelerator conveyor 1.20

The disadvantage of such a device is the possibility of destroying the plates being processed at the time of their fall on the intermediate accelerator conveyor.

The closest technical solution to the invention is a plate feeding device comprising a frame, a rack for a plate pack, a roller table and a hinge / billet frame containing a grip for plates 2.

However, when using this device, manual operations are used and, moreover, it cannot be used in continuous production with a given rhythm in automatic mode.

The purpose of the invention is to increase productivity.

This is achieved by the fact that the plate supplying device, which includes a frame, a rack for the plate package, a roller table and an articulated swivel frame containing the gripper for the plates, is equipped with a driving carriage on which the articulated swivel frame is installed, and the rack for the plate package is removable, moreover, the gripping plate contains fixed and movable stops.

FIG. 1 shows the proposed plate feeder, general view; in fig. 2 - the same, the fork on top in the initial position; in fig. 3 shows the installation of sensors for automatically forming a predetermined interval between the plates. The plate feeding device, which feeds and stacks pieces by piece in automatic mode into the receiving roller table 1 of the production line, consists of a bed 2 installed perpendicular to the longitudinal axis of the production line, a drive carriage 3 that can be moved along the track 4, perpendicular to The axis of the production line. The trolley drive is made from hydraulic cylinder 5. On the trolley there is mounted a swivel frame 6 with a rotary drive from hydraulic cylinder 7, the upper 8 and lower 9 stops are mounted on the rotary frame, between which the workpiece plate 10 is clamped. The upper stops 8 are fixed, but have a set-up installation depending from the width of the slab-blank. The lower stops 9 are movable and press the plates against the upper stops. The movement of the lower stops and the clamping are carried out by two hydraulic cylinders 11. On the bed 2 there are latches, along which a removable rack 12 with a pack of plates is installed and fixed. The rotary frame 6 of the stacker in its original (horizontal) position with its longitudinal beams is placed in the openings 13 of the bed of the receiving roller table 14 in such a way that the bearing surface of the rotary frame that is in contact with the lower plane of the slab-blank, is below the level of the upper forming rollers of the roller table ( about 10-12 mm). To ensure the automatic switching of the speeds of the intermediate role of Gang 14, the formation of a predetermined nominal interval between the blank plates on the production line, three sensors are installed on the intermediate roller table, limit switches 15, 16 and 17 that are affected by the plate moving along the roller table and on the receiving roller table are installed the limit switch 18, which gives a preliminary command to turn on the conveyors 1 and 14. The device for feeding plates in the automatic mode works as follows. Plate-blank (plate number 2), laid with a rotating frame of the device on the rollers of the receiving roller table 1 (see Appendix 1) affects the limit switch 18 installed on the receiving roller table, which gives the command to turn on the drive of the receiving roller table. At the same time, a command is given to connect the drive shaft of the intermediate roller table to the drive of the receiving roller table so that the speed of the intermediate roller table is equal to the speed of the receiving roller table. At the same time, switching on the end switch 18 is possible only if the previous plate (plate No. 1) has completely transferred from intermediate roller table 14 to the conveyor 19 of the coarse grinding machine, i.e. if limit switch 15 is released from pressure by plate No. 1. The plate the workpiece begins to move and moves from the receiving roller table to the intermediate roller table (see position II). In this case, the turning frame of the device is in the initial (horizontal) position, i.e., the frame beams are recessed in the openings of the receiving roller table bed, and the supporting surface of the frame on which the slab is laid is below the upper forming rollers of the roller table. During its further movement along the intermediate roller table of PLKT No. 2, its front edge acts on the limit switch 16, which gives a command to stop the drive of the direct roller table, i.e., the receiving and intermediate roller tables stop. At the same time, the previous plate (plate No. 1, position III), moving from the intermediate roller table to the conveyor 19 of the coarse grinding machine, continues to move with this conveyor and when its rear edge leaves the limit switch 17, the distance A between the rear edge of plate No. 1 and the front edge of plate No. 2 (position III) will correspond to the specified interval. In this case, the limit switch 17 commands the connection of the drive shaft of the intermediate roller table to the conveyor drive of the coarse grinding machine, i.e. the intermediate roller table receives a speed equal to that of the coarse grinding machine 19 and the plates No. 1 and No. 2 continue to move at the same speed and interval A between them. When the stacker's frame turns from its original position by 90 °, it acts on the limit switch mounted on the device trolley, which gives a command to move the cart towards the rack with the plate pack installed on the frame and stop the frame turning. When a rotating frame trolley approaches a plate pack, the limit switch mounted at the bottom of the swing frame touches the front plate of the bag and gives a command to stop the cart and turn the swing frame to a position where its supporting surface will touch the plane of the front (first) plate package. For the final stop of the rotary frame, two pins are installed in its upper part, which, resting against the blank plate, act on the limit switches that command the stopper of the rotary frame to stop and simultaneously move the lower stops 9. At the same time, the lower stops engage the front plate package and move it up until it rests against the upper stops 8 and is clamped between the stops. When it moves up, the plate at the end of the stroke presses on the pins located in the upper stops, which act on the limit switches, giving the command to end the clamp and move the cart with the swivel frame and the slab-plate clamped in its stops in the opposite direction, i.e. roll table.

At the end of the return stroke of the trolley, when it approaches the receiving roller table, it acts on the limit switch that commands the rotation of the stacker's pivoting frame with the clamped slab in the initial (horizontal) position. Prior to the final approach of the pivot frame to the initial position, 10-15 °, it acts on the limit switch, which gives the command to withdraw the bottom stops and unclamp (release) the slab-blank. With further rotation of the swing frame to the horizontal position

it is embedded in the openings of the receiving roller bed, and the plate is laid on the rollers of the roller table and acts on the limit switch 18. The next cycle of the stacker operation begins.
