Description

The invention relates to the packaging of ring-shaped objects, namely, wrapping them with steel tape, as well as with wire, and can be used in various sectors of the national economy, in particular, in the tire industry when wrapping tire packages. A device for wrapping a keta of ring-shaped objects, containing a frame, belt feeding and tensioning mechanisms, a fastening and tapping unit / and a rotary bar-ban 1 mounted on a horizontal hollow axis, is known. on and the unreliability of work. The purpose of the invention is to simplify the design and increase reliability. To achieve the goal, the device for wrapping a package of ring-shaped objects containing a frame, a feed mechanism and belt tension, a belt fastening and cutting unit, and a rotary drum mounted on a horizontal hollow axis are provided with a rod placed inside a hollow fixed axis which is equipped with a bag compression mechanism, and another is connected with a rod of a power cylinder mounted on the frame, the bag compression mechanism consisting of a drive housing and spring-mounted arcuate levers fixed on it, the free ends of which have rollers, while on the side surface of the rotary drum grooves for the passage of the rollers are made. FIG. 1 shows a device for dL wrapping a package of ring-shaped objects, a general view; in fig. 2 is a view along arrow AJ in FIG. one; in fig. 3 section BB in FIG. 1. A device for wrapping a package of ring-shaped objects comprises a frame 2 mounted on a frame 1, on which panel 3 is mounted with mechanisms 4 and 5 for feeding and tensioning the tape, mechanism 6 for fastening and cutting the tape, a fixed frame 7 moving on it a power cylinder 8, a movable frame 9, and a drum 11 rotatable relative to a horizontal fixed hollow axis 10 having a certain number of driving channels 12

with folding spring-loaded crimpers 13 for passing the tape 14, on the lateral cylindrical surface of which longitudinal grooves 15 are made, and located inside the fixed one. The hollow axis 10 has a rod 16, at one end of which a package 17 is pressed, the package is made in the form of arcuate levers 18, one end of which is fixed by means of axes 19 on the housing rotating relative to the rod 16. and interconnected with the longitudinal grooves 15 of the drum, while the other end of the rod is connected to the rod 21 of the power cylinder 22 ,. mounted on the frame 2 of the device.

The levers 18 rotate with respect to the axes 19, are released by the springs 23. The rear thrust disk 24 of the drum serves as a support surface for 20 of the package 25, and the front disk 26 has grooves in contact with the spring-loaded levers 18. The drum 11 has a toothed rim 27 located in the rear clinging with gear 28 drive ba .75 Abana.

The mechanism panel 3, movable 9 and fixed frame 7 have belt-feeding channels 29-31 with spring-loaded lids not shown, which together with one of the channels of the drum 11 form a tape passage closed around the package 25 of ring-shaped objects through their inner opening.

The device works as follows. in a way.

The movable frame 9 is in the open position. The bag 25 is put on the drum 11, the power cylinder 22 is triggered by moving the press mechanism 17 in the direction of the drum thrust disk 24 by means of a drill 40.

At the same time, the levers 18, slipping through the arcuate surface along the limiting-45 grooves of the disk 26, under the action of the springs 23 emerge from the grooves of the drum 15 and become in the extreme upper position.

 With further movement of the levers

18 abut the pack 25 and, pressing the latter against the stop disc 24, compress the interp to the desired value. To reduce friction between the levers 18 and the bag 25, the levers 18 have rollers 20. When the drive (not shown) of the tape feed mechanism 4 is turned on, the tape 14 is fed through a channel closed around the packet. As soon as the front end of the tape 14, having made a revolution around the package 25, enters the lock zone, the tape feed mechanism 4 stops, then the front end of the tape is clamped, the belt tension mechanism 5 and 65

it, pressing the spring-loaded lids, exits the closed channel and tightly fits the package 25. The belt tensioning mechanism 5 is turned off, and the belt fastening and cutting mechanism 6 performs the operation of locking and cutting the ribbon. The power cylinder 8 of the Movable frame 9 is turned on, raising it to the upper position, and the drum drive, turning it over the toothed rim 27 at a predetermined angle. In this case, the other channel of the drum 11 is aligned with the channels 30 and 31, and the wrapping process of the bag repeats with.

The number of possible packages per package depends on the number of channels 12 on the drum 11. After the wrapping process is completed, the cylinder 22 is actuated by moving the rod 16 to its original position. In doing so, the levers 18, resting against the front disc of the drum 26, are lowered into the grooves 15 of the drum and release the tied bag, which is then removed from the drum. Further, the whole process is repeated.

The proposed device makes it possible to simplify the design of the device due to the arrangement of the power drive of the pressing mechanism outside the drum and. eliminating the need to supply air (hydraulic fluid) to the rotating cylinder, as well as to increase its reliability due to the absence of the clamps sliding along the inclined guides.
