(54) DEVICE FOR DAILY FEEDING FROM THE FOOT

CARDBOARD FLAT PREPARATIONS OF BOXES

and their formation

one

The invention relates to the field of packaging products in containers and can be used in the food, light, chemical and pharmaceutical industry industries.

A device is known for the direct feeding from the stacks of cardboard flat-laid boxes and their molding, which contains a blank magazine, a conveyor with a gripper for the blank and a device for opening it 1.

The closest solution to the invention by technical essence is the device d, I пош single feed from the stack of cardboard flat billets of boxes and their formation, containing a magazine for billets, a mechanism for single feed 3ai-OTOBOK, a conveyor with a grip for the billet and a device for opening it 2 .

However, the known device does not provide the possibility of reliable operation, since it has a complex kinematics.

The purpose of the invention is to increase the reliability of the device by simplifying its kinematics.

This goal is achieved by the fact that in the device for the individual supply from the stack of cardboard boxes, 110 folded billets and their formation, containing a magazine for blanks, a mechanism for the continuous supply of blanks, a conveyor with a gripper for the blank and an opening device according to the invention uncover the workpiece consists of mounted obliquely

e, the magazine for blanks of paired plates for bending the valves of the blanks, as well as from along the movement of the blanks and fortified oblique guides to open the blanks and horizontally installed guides for fixing the valves and the opened blanks, while the figured guides parallel to the last guides; not to close the valves of the opposite end of the workpiece, one of which is fixed on the grab of the conveyor. FIG. 1 shows schematically a device for the single-step feeding from the foot of cardboard and flat-folded blanks of boxes and their formation, general view; in fig. 2 - molded cardboard box.

The device comprises a billet magazine 1, made of a bottom 2, supporting guides 3 and a plate 4 regulating the clearance for passage of a single billet 5. A mechanism 6 for single-piece feeding of billets includes a gripper 7 driven by, for example, a chain conveyor 8 or pneumatic cylinder. The conveyor 9 is a chain conveyor 10 provided with a claw 11 with a figured impaler 12 fixed on it to close the valve 13.

The workpiece opening device {r1 consists of obliquely installed in front of the magazine for blanks of paired plates 14, bending the valve 15, and paired plates 16, bending the valve 17 arranged along the movement of the workpiece and horizontally installed directions 18 for fixing the valve 19 in the bent position, fixed oblique guides 20 and 21 to give the blank a volumetric shape, horizontally mounted guides 22 for fixing the valve 23 in a bent position, arranged parallel to the last figure hydrochloric guide 24 for closing valve 25, shaped guide 26 for closing valve 27, shaped guide 28 for closing the valve 29 and the confining plates 30.

The device works as follows.

The magazine 1 is filled with flat-laid workpieces 5. The first from the bottom, the workpiece 5 under the action of the gripper 7 moves in the direction of the tool for opening the workpiece and slides over the paired plates 14 and 16. Falling between the paired plates 14, the valve 15 is folded down, causing the valve 19 to bend down with itself The valve 17 is folded upward under the action of the paired plates 16, causing the valve 23 to bend together with itself. After the workpiece 5 has been completely pulled out of the magazine 1 and the valves 15, 17, 19 and 20 are bent, the conveyor 9 with grip 11 moves the workpiece 5 along a fixed horizontal and oblique guides. In this case, the valve 19 enters the gap between the two fixing guides 18. The valve 17 comes out of contact with the paired plates 16, and the valve 23 continues to be held by them. Then the valves 15 and 19 come out of contact with the paired plate. 14.

Upon further movement of the workpiece, the plane of the guide 20 falls between the flaps 17 and 23.

the inner surface of the valve 23, the guide 20 causes the blank 5 to acquire a three-dimensional form. In this case, the valve 23 with its external surface abuts against the guide 21, which limits the bending of the valve and contributes to the opening of the box. Further, the valve 23 enters the gap between the guides 22, which fix it bent upwards. In the process of purchasing the bulk-shaped billet 5, the valve 13 closes as a result of interaction with the figured guide 12. At the same time, the valve 25 closes, moving along the figured guide 24. After that, the valves 27 and 29 are closed, interacting with the figured guides, respectively and 28. At the same time, the upper surface of the crate is fixed by the limiting plate 30. The crate is prepared for filling. A device for single-piece feeding from the stack of cardboard flat billets of boxes and their formation ensures an increase in the reliability of the device operation by simplifying the kinematics of this device.
