Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a labeling machine for packaging briquettes that applies a label to the packaging surface of 7 charcoal briquettes stacked in two stages.

As is well known, when charcoal briquettes stacked in two stacks of seven briquettes are packaged, they exhibit a substantially hexagonal packaging shape when viewed from above. The present invention provides a labeling machine for briquette packaging that automatically attaches a horizontally long label to such a briquette package, centering on one side corresponding to a hexagonal side of the briquette package, and extending to both adjacent sides thereof.

According to the invention, there is provided a pivot frame, a device for pivoting the frame between a vertical position and a horizontal position; a suction head for suctioning and holding the hexagonal briquettes; a device for applying adhesive to the label on the suction head while the rotating frame moves from a vertical position to a horizontal position; and a device for applying adhesive to the label on the side of the hexagonal briquette package. a device for moving the suction head towards the briquette pack in order to remove the suction head; A charcoal briquette package comprising stopped side blocks, the side blocks being configured to rotate toward the side portion adjacent to the side surface when the central block abuts the side surface of the briquette package. We provide labeling machines for

An embodiment of the apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.

Referring now to the drawing, the base 1 is installed at a position where a hexagonal briquette package A is carried when viewed from above,
A support frame 3 having a support stand 2 is attached to this base.
is fixed. A substantially U-shaped pivoting frame 4 is fixed to an axle 6 supported in a bracket 5 of the support frame 3 and is pivotable between a substantially vertical position and a substantially horizontal forward position.
A pinion 7 is fixed to one end of the shaft 6, and the base 1
A rack 9 on the piston rod of the upper hydraulic cylinder 8 meshes with this pinion 7. By operating the hydraulic cylinder 8 and moving the rack 9 in the front and back direction,
The pinion 7 rotates, which causes the pivoting frame 4 to pivot between vertical and horizontal positions.

The suction head 10 has a central block 11 having a length corresponding to one of the hexagonal sides of the briquette package A.
and a side block 12 which is hinged 12' on both sides, and has an exhaust system (not shown) inside.
The suction head 10 is connected to the perforated plate 13 of the suction head 10 so that the suction action is performed. The central block 11 has a pair of spaced apart support rods 14.
It is supported from the revolving frame 4 by inserting the support rod into a guide tube 15 fixed to the top of the revolving frame 4 in a removable manner. A hydraulic cylinder 17 is fixed to the top of the pivot frame 4, and a piston rod 18 of the hydraulic cylinder 17 extends inwardly through the pivot frame 4 and is connected to a pusher plate 19. A coil spring 20 is wound around the support rod 14 between the pusher plate 19 and the central block 11 of the suction head 10. Side block 12 and pusher plate 1
9 are interconnected by pivot links 21, and thus:
Pusher plate 19 for central block 11
Via the pivot links 21, the side blocks 12 can be pivoted relative to the central block 11 about the hinges 12' when the two blocks move toward each other.

In the vertical position of the rotating frame 4, directly below the suction head 10 is a magazine 22 for storing labels.
There is an adhesive tank 23 supported by a support stand 2 immediately in front of it. A coating roll 25 for applying the adhesive 24 in the tank 23 to the label suctioned and held by the suction head 10 is rotatably supported at both ends by a pair of support arms 26. A rod 28 whose lower end is pivotally connected to the pusher plate 27 extends upward through the frame 3 on the outside of both ends of the adhesive tank 23, and its upper end is inserted into the support arm 26. The rod 28 has a spring receiver collar 29 fixed thereto, and a coil spring 30 is wound around the rod 28 between the support arm 26 and the collar 29, and the coil spring 30 is wound around the rod 28 between the support arm 26 and the collar 29.
8. The hydraulic cylinder 31 is mounted vertically on the base and its piston rod 32
is connected to the pusher plate 27, and when the hydraulic cylinder 31 is in the retracted position, the applicator roll 25 is immersed in the adhesive 24 in the tank 23, and the hydraulic cylinder 31 is activated to push the pusher plate 27. When pushing up, the rising of the rod 28 pushes up the support arm 26 via the spring 30, thereby lifting the applicator roll 25 from the adhesive surface. In this raised position, the applicator roll 25 is in such a position that the label on the suction head contacts the roll surface of the applicator roll 25 during the pivoting of the pivoting frame 4 and applies the adhesive on the roll surface to the label.

It is assumed that the briquette pack A is now brought to the labeling position, one of the sides corresponding to the sides of the hexagon is facing forward, and the pivoting frame is in the vertical position. First, the hydraulic cylinder 17 is actuated to extend the piston rod 18, thereby causing the suction head 1 to extend.
0 toward the labels in the magazine 22, and one of the labels is attracted to the suction head 10 by the suction action of the suction head 10. Next, the hydraulic cylinder 17 is reversed to temporarily raise the suction head 10 to its original position. The hydraulic cylinder 31 is actuated to push the applicator roll 25 up from the adhesive 24 in the tank 23. Hydraulic cylinder 8 is then actuated to advance rack 9, thereby rotating pinion 7 and pivoting frame 4 from the vertical position to the horizontal position shown in dotted lines in FIG. During this rotational movement, the label suctioned and held by the suction head 10 comes into contact with the coating roll 25 in the raised position and is coated with adhesive. At this time, since the applicator roll 25 is elastically supported via the coil spring 30, the applicator roll 25 comes into close contact with the label and transfers and applies the adhesive adhered to the roll onto the label reliably and evenly. After application, the application roll 25 is lowered into the adhesive 24 in the tank 23 by the retraction actuation of the hydraulic cylinder 31. While the pivoting frame 4 is in a horizontal position, the hydraulic cylinder 17 is actuated to extend the piston rod 18. The suction head 10 then advances towards the flat side of the briquette pack A until the central block 11 of the suction head 10 comes to rest against this side. At this time, the center part of the label is attached to the side surface of the package. piston rod 18
continues to expand even after the central block 11 has stopped, so the pusher plate 19 moves forward with respect to the central block 11 while compressing the coil spring 20, and as a result, the side blocks 12 are moved through the links 21 to the hinges 12'. Rotate around to apply both ends of the label to a corner or adjacent flat side of the package. After pasting, when the piston rod 18 with the hydraulic cylinder 17 reversed is retracted, the pusher plate 19 first rotates the return side block 12 to its original position, and subsequently pulls the suction head 10 back to its original position. . The hydraulic cylinder 8 is then actuated to retract the rack 9, thereby returning the pivoting frame 4 to its vertical position in preparation for the next cycle.

Since the present invention is constructed as described above, a label can be automatically and efficiently attached to the side surface of a hexagonal briquette package when viewed from above. Also, since the suction head consists of three blocks, the side blocks being hinged to the central block, it is possible to apply the label widely and reliably over one of the sides of the package and the adjacent side part. can.
