Abstract

The invention relates to packaging products in containers and can be used in the food industry. The purpose of the invention is to increase the reliability of work. The device for single-piece submission from the stack of cardboard flat-laid boxes and their formation includes a magazine 1, a vacuum gripper 3 located on the carriage 4, fixed benders 6.7 valves, a pusher 12, a spring-loaded stop 15. The vacuum gripper 3 grips the flat-folded box and retracts, when this is the formation of the box, after which the pusher 12 moves the box along the guide rails 18. 2 Cp f-crystals, 2 Il.

Description

The invention relates to packaging products in containers and can be used in the food industry.

The purpose of the invention is to improve the reliability of the work by eliminating the possibility of skewing, jamming and deforming the workpiece during feeding and shaping.

Figure 1 shows a diagram of the device, figure 2 - braking device.

A device for single-piece feeding and forming of cardboard flat boxes from a stack contains a magazine 1, a device 2 for opening the boxes, a vacuum gripper 3 located on the carriage 4, fixed guides 5 for the carriage 4,

mounted with the possibility of moving in the horizontal plane, fixed benders 6 and 7 valves, a device for closing the rear valve, containing a plate 8 with a groove rigidly mounted on the carriage 4, kinematically connected by means of the rod 9 with a roller 10, mounted with the possibility of movement in the groove of the plate 8 with a movable beater 11, a mechanism for moving the opened boxes, made in the form of a horizontal pusher 12 with a direction 13, a pneumatic cylinder 14 and an anvil 15 opposite to it, springs springs 16 on rods 17 with guides 18, not st - 3aHFforo with horizontal pusher

12-. The device can be equipped with a mechanism for fixing the spring-loaded abutment in the extreme position, comparing from the trigger bar 19, spring-loaded spring 20, connecting rod 21 pivotally connected to the retaining bar 22 with the stop 23, spring-loaded rod 24, and a mechanism for smoothing supplying a spring-loaded stop 15 from the extreme position to the initial position, consisting of a shaft 25 with blades 26 placed in a cylinder 27 with brake fluid, a rack and pinion gear whose gear 28 is fixed on the shaft 25 and connected with a cam clutch 29. For retracting the box to the table 30 th oic product pusher can be applied 31 mounted on the conveyor 32.

A device for single-piece feeding from the stack of cardboard flat-laid boxes and their formation works as follows.

The vacuum gripper 3 on the carriage 4 moves along the guides 5 until it is in contact with the front flat-laid box in the magazine 1. After its gripping, the carriage 4 is retracted and, in contact with the opening device, the box is formed, i.e. acquires cross-sectional shape of a rectangle. Upon contact with the sub-bend 6, the front valve closes. At the same time, the bending mechanism 11 closes the rear valve by means of a pull 9 with a roller 10, which moves in the plate 8 with a groove rigidly connected to the carriage 4. The side flaps close when in contact with the figure bend 7. The formed box enters the corners that serve as the pusher 12 and an anvil 15, then the pneumatic cylinder 14 moves the pusher 12 in the direction of the 1M 13, moving the box along the rails 18 and expanding the spring 16 rods 17. In the extreme position the rods 17 are fixed with a locking plate 22. The pusher 12 returns to its initial position presses against the trigger bar 19, which, by means of the pulley 21, releases the rods 17 from the locking bar 22, and the anvil 15 begins to move, and the gear, rigidly connected with one half coupling of the cam clutch 29, begins

to rotate, the second half-coupling is rigidly fixed with the shaft 25 with the blades 26 placed in a cylinder with brake fluid. Due to the resistance of the brake fluid, the rotation of the shaft slows down, i.e. the movement of the rods 17 is slowed down. Then the pusher 31, installed on the conveyor 32, pushes the t-gun onto the finished product table.

After shearing the crate with the pusher 12, the carriage 4 begins the next cycle.
