Abstract

PURPOSE: To make a mandrel mounted in a turret type, rotatable only when it is in a specified position by providing a driving means for engaging and disengaging the mandrel in relation to driving force when the mandrel enters and is spaced from a specified position of a frame. CONSTITUTION: Before a mandrel is positioned into a web storage position, a driving pulley 40 corresponding to this mandrel is engaged with a driving belt 38 as a core approaches a specified position. The mandrel starts rotating with this engagement. After the core reaches the specified position, a bonding unit moves horizontally, and an applicator roller comes in contact with the core by one rotation portion of the core to apply an adhesive to the core. After this application, the bonding unit is retreated, and a cutting unit is advanced to cut off a label storage web. A turret is successively index-rotated to remove a core full of labels, from the turret, and the driving pulley 40 corresponding to the mandrel gripping the core is separated from the driving belt 38 to stop the rotation of the mandrel.

[5@Akira's Overview] The present invention is based on a type of plate or disc that protrudes from the shore side, is supported so as to rotate within a bearing in each disc, and has a driving pulley at the other end. An automatic label transfer turret rewinding device consisting of a large disc with a number of core supporting mandrels. Two or three mandrel drive pulleys are engaged on the drive bell at times ti and the remaining pulleys are undriven and in an "idle link" condition. A bonding unit is movable relative to the core of the mandrel and has a cooperating cutting blade or knife. The adhesive unit is then retracted and the knife blade passes through the area between the two cores on adjacent mandrels, cutting the web, if any, and forcing the web onto the newly applied adhesive core. do. The turret is positioned at a new location. The core is wrapped with a web of labels and the process is repeated until the core is filled with the desired number of labels. After positioning to the idler position, the wound core is f
and placed on an empty core or mandrel.

each core has a segmented friction core holder;
This halter grips the core as the mandrel rotates, and a simple manual operation by the operator releases this clip to the mandrel.

OBJECTS OF THE INVENTION The main object of this invention is to provide a method for rewinding label support webs into small rolls or cores with very high precision but with minimal personnel.

It is also an object of the invention to provide a method for rotating a mandrel mounted in turret fashion on a rotary plate by a certain amount when in position.

It is also an object of the invention to provide a device for rewinding webs of material, such as label support webs, which is safe and easy to handle.

Another object of the invention is to provide a means of holding the core securely on the mandrel, but also easy to remove.

EXAMPLES The above objectives will become readily apparent from the following detailed description and the accompanying drawings.

Referring to FIG. 1, a large disk lO is mounted for rotation on a frame or base 12 about an axis 13. Referring to FIG. There are eight label friction mandrels or spindles 14 on the disc 10, all of which protrude from one side of the disc IO and are driven from the other side.

Each mandrel 14 having a flat surface in the long f direction 6 has 1
It carries a core 18, typically made of cardboard, fiberboard, vinyl, plastic or other resilient material. The core 18 is held on the mandrel 14 by a pair of semi-circular plate-shaped pieces 20.22, each having a slightly offset center 24.26. Each plate 20 is the same as the plate 22, but the orientation is reversed when assembled. The mandrel 14 has a pair of longitudinally upper planar surfaces 16, as shown in FIG. 3, and is assembled so as not to rotate about the offset center. Each piece 20.22 may have an annular outer groove 30 that accommodates an elastic band or O-link 32 so that it can be held in place with the mating piece.

The back side of the taleud unwinding base 12 has drive means including a pulley 36 driven by a motor and a drive pulley structure that engages the drive belt 38 or at any time two or three of the mandrel drive pulleys 40. (See Figure 2). An idler pulley 42 is provided to create the proper tension on the belt 38 and the proper drive angle of the belt 38 with respect to each pulley 40 in the driven position.

The adhesive unit 44 includes an adhesive container or tank 46;
It includes an applicator roller 48 mounted in the reservoir such that a portion of the roller extends into the adhesive in the reservoir, and means for laterally moving the adhesive unit into and out of engagement with the core 18 on the spindle. The adhesive unit is mounted on a track 50 connected to the base 12 and reciprocated along the track by an air cylinder (not shown). This adhesive unit may support a lower adhesive carrier roll 52 that is partially submerged within the adhesive in the bath 46 and in contact with the applicator roller 48 , such that the carrier roll transfers the adhesive to the applicator roller 48 . The diameter of the applicator roller can be smaller than that required to coat the adhesive and thus extend into the adhesive in the bath. Additionally, the use of this carrier roll 52 prevents excess adhesive from getting onto the applicator roller and core.

A web cutting assembly 56, including a cutting blade 58, is attached to the frame 12.
It is mounted on a track 60-L fixed to and moves horizontally. A solenoid actuated pneumatic cylinder 2 is connected to this assembly to move the water along track 60. Other solenoid actuated pneumatic cylinders control the vertical movement of the blades. The cutting FfrM1 volume includes a sea urchin roll 66 that controls the angle and path of the web as it is cut.

If desired, the blade 58 can be set to cut at an angle of 45° from overlapping.

Positioning of the mandrel containing each core to the next position is automatically controlled. A counter may be provided to accurately count the number of labels on the core, so that when a predetermined number is reached, the cutting assembly and blade are actuated to rotate the disk to a new orientation and remove the mandrel. to the next position and generates a signal that activates the adhesive unit to apply adhesive to the newly positioned core at the preliminary position.

A detector with a photocell 70 is focused at the location indicated by reflector 72, and the detector beam is adjusted to just miss the mandrel if not cored to the mandrel. The detector has an audible alarm which also prescribes an emergency stop and prevents further north of the turret device until the label or web receiving roll can be removed from the mandrel in the focused position shown at 75. Prevents positioning.

In operation, core 18 is placed on mandrel 14 before the mandrel is positioned in position for web accumulation. As the core position 11 BA is approached, the mandrel begins to rotate as it engages the drive pulley 40 or drive belt 38 associated with that mandrel. After the core reaches the position shown at 18A, the adhesive unit moves horizontally and the applicator roller 48 contacts the core for one revolution, and the applicator applies one revolution of adhesive to the core. ,
The exact time of its application is computer controlled. Adhesive unit or retract. Once the active core is filled, the cutting unit moves forward to cut the label containing web, the turret is positioned, and the gluing unit applies adhesive to the next core.

The action of lowering the blade and cutting off the web actually acts to push the web down against the adhesive-applied core, so that immediately after retraction of the blade, the core has already accumulated a label. Thereafter, the turret IO will be positioned to the next station icon, ie the disk will rotate 1/8. On the label-・
The cupped core 18 is disengaged after the turret has been positioned twice and is no longer engaged by the drive pulley or drive belt 38 associated with the mandrel gripping the core and the mandrel no longer rotates. The empty core is rotated before the adhesive is applied and continues to rotate while the label is being filled. The core can then be removed for positioning to the next station.

The extended flat side of each of the seventeen mandrels fits into the semi-disc-shaped sections for the core when they are deflected to form a non-circular center gap.

As the spindle 14 rotates in the actuating direction, it exerts a force on the separate centers of the plates, tending to force them into a rounded shape rather than a slightly offset semicircular shape.

This opposing pressure on the core releases external forces from the mandrel, allowing the core to easily detach from the mandrel.

Normally, the first winding of the rewinding device takes twice as long as the rewinding device. For labeling devices such as portable label applicators, rewinding devices are used to rewind large rollers onto smaller, easily handled rollers. Using this invention, the manpower requirement is reduced by at least two to three rewinding workers, as well as a dramatic reduction in label production costs.

Alternatively, the half-disc shaped pieces could be made wider than shown, so that only one pair of pieces would be needed to support the core. When two pairs of pieces are used, each opposing pair can be connected by a spacer 80 or a pair of spacers 82, such as dowel rods, as shown in FIG. A safety guard 86 may be provided to prevent the cutting blade from coming into contact with people.

[Effects] From the foregoing, we have developed a method and apparatus for rewinding the label support web onto a small roller or core with very high precision and with a minimum of total available personnel, and which is mounted in the form of a turret on a rotating plate when in position. It is easy to see that he invented a method for rotating only selected mandrels. It provides a means for firmly holding the core in the Mannl='Lerch, but for easy removal, as well as a device for rewinding webs of material, such as label support webs, that is safe and easy to handle. Although a preferred embodiment of the invention has been described, it should be understood that the invention is not limited to this embodiment, but that any modifications within the scope of the claims may be included in the invention.
