Description

The invention relates to the packaging of products in boxes and can be used in the food, light and other industries.

The purpose of the invention is to increase the reliability of the device and expand its technological capabilities - after opening the flat-laid blank of the carton box and in the process of giving it a three-dimensional shape, it is transferred from the horizontal plane to the vertical one and after closing the bottom valves it can be transferred - Least operations without a special carrier.

FIG. 1 schematically shows a device for single-piece feeding from the stack of cardboard flat billets of boxes and their volumetric formation; in fig. 2 and 3 - the device of the swinging stops; in fig. 4 - formed box.

The device comprises a magazine 1 for blanks, a mechanism for their single submission, containing a carriage 2 and an anvil 3 mounted on it. A magazine is provided with a device for opening the blanks in the form of swinging stops to form a gap between the upper and lower longitudinal valves. On the conveying mechanism 4, a gripper is installed, made in the form of two U-shaped plates 5 with the possibility of placing them in a slot formed by tilting lugs and holding the drawer 6. To give a volumetric shape to the workpiece and close the transverse valves, a pusher 7 serves as a feeder for the guide 8 to close the front cross flap, and the flexor 9 serves to close the rear flap.

The guides 10 hold the box when moving it to the figured guides 11 closing the longitudinal flaps. The swinging stop 3 comprises a bracket 12, a swinging bar 13 mounted obliquely, a return spring 14 and a screw 15 regulating the swinging of the stop.

The device works as follows.

The magazine 1 is filled with flat billets of cardboard boxes 6, laid horizontally between the vertical guides. The carriage 2, moving, seizes the support 3 from the bottom of the bottom blank and feeds it to the swinging stops.

The swing stops in the initial position are inclined to the plane of movement of the workpiece at an angle of 30-45 °, so that the workpiece, moving, abuts against the inclined plane of the bar 13 and causes it to rotate. As a result of the rotation, the bar 13 descends below and squeezes the transverse flaps 16 and 17 together with the longitudinal flaps 18 and 19. And since the flaps 20 and 21 are still clamped at this time

between the carriage 2 and the stack of blanks in the store 1 and remain horizontal, then between the valves 20 and 19, as well as 19 and 21, slots are formed, in which the bars 13 and the lower flanges behind them

R. U-shaped plates 5.

The carriage 2 with the workpiece is moved until the workpiece leaves the planks 13, which are returned to their original position by the action of the spring 14. Then, the transport mechanism 4 lifts the workpiece from a horizontal to a vertical plane. At the end of the stroke, the billet box rests against the wall with the valves 16 and 17 into the curved part of the flap of the pusher 7 and obtains a three-dimensional shape.

The next step is to close the valves.

0 The pusher 7 pushes the box 6 out of the U-shaped plates 5 onto the front valve bend-on valve 22 for a length of 100–200 mm.

Then, the bend-in knob 9 closes the rear flap 17. Next, moving simultaneously, the plunger 7 and the bender 9 push the drawer onto the guide 8 between the guides 10. During this movement, the figured guides 11 close the longitudinal valves 20 and 21. At the end of the cycle the crate can be transferred.

0, for gluing into a device for gluing the bottom or for filling it with a product, and the mechanisms return to their original position, and the cycle is repeated.
