Abstract

The severed end of a continuous, traveling web (11), such as paper, being wound into a wound web roll (12) is attached to the web roll, without requiring human touch, by a pair of adhesive applicators (23, 24) which are mounted on guides (19, 29) to travel longitudinally parallel with the axis of the roll being wound. The applicators may apply either a stripe of glue (21, 22) or an adhesive tape to the circumference of the wound paper roll during the last revolution of the wound web roll, preferably at two locations intermediate the end arm supports (13, 14) of the wound web roll. The applicators are moved radially inwardly to a working position and outwardly to a stand-by position relative to the axis of the rotation of the wound web roll so as to be retracted in the stand-by position when the last wrap of the web on the roll is made to attach the severed end of the web onto the finished wound web roll.

Description

[Detailed description of the invention] A device for applying adhesive to a web roll wound on a winder. Industrial application field The present invention provides a paper-like winding of a predetermined diameter from a moving substantially continuous web. It relates to forming successive web rolls one after another. In particular, the invention , slightly downstream of the length of the web to produce a wound web roll of the desired diameter. Adhesive to the area of the web that has been cut or is about to be cut to give it a The present invention relates to a device for attaching. More specifically, the present invention provides The circumference of the web roll is wound up so that the last ramp of the web is pasted around it. Relating to a device for automatically applying an adhesive band or adhesive tape circumferentially around a surface . The equipment that performs this task operates without the need for human intervention.

Vagina I sword load In conventional machines that wind the moving web onto take-up rolls, the web The severed tail end of the Place the double-sided adhesive tape under the final layer of the web or towards the outer edge of the cut web. They are artificially attached to the winding roll, either because they are used for one or the other. . Several application devices are commercially available for artificially applying adhesive or tape in this way. Available at.

These methods require physical proximity of a human operator to the machine; This has exposed them to the inherent dangers of accessing moving machinery. most Applying adhesive to the winding roll to seal the final roll is This inevitably introduces undesirable variations in both the amount of adhesive used and the location of the adhesive. both of which reduce the desired uniformity and quality of the finished rolled product. The result is that

Secure the outer layers of the web using a means such as a stapler to form the final web layer. It is also conceivable to press it into a wound roll so as to keep it in the roll.

An advantage of the present invention is that in order to adhere the end portion of the web to the wound web roll, the final winding of the roll (e.g., before the last turn of the web) By providing a device that evenly applies adhesive to the web near the edge of the strip, Yes, this entire process involves a worker working on a running machine and a rotating hoisted web. Stops the roll during winding so that there is no need to approach and the web at the end is fixed. This can be achieved without the need to do so.

Main type Ω overview In a preferred use of the invention, the adhesive band or double-sided adhesive tape is One of the final turns of the web as it is wound into a winding web roll Attached to the outer surface of the lower front. In this method, the final turn of the web is its inner On the top, the adhesive vanodnu comes into contact with the adhesive tape, but not on its outer surface.

Preferably, the adhesive application is rolled to give an uninterrupted adhesive deposit. It is better to do this along the entire circumference of the web roll; however, if desired In some cases, a dotted or chain line of adhesive is applied along the circumference of the rolled roll. It is also quite possible.

In a preferred embodiment, adhesive adhesion of the web to the wound web roll is Along two spaced apart parallel lines extending around the circumference of the web roll Given. Cover by placing these adhesive lines on the side edges of the web. The overlying web can be fixed to act as a firm cover. , the adhesive adhesion supports the core or spool onto which the web is wound. It is easier to synchronize with the supporting arm. In particular, the adhesive application device along with the machine, i.e. longitudinally with respect to the wound roll. It can be mounted so that it can move in either direction.

The solution provided by the invention is that the rolls are spaced axially along the length of the roll. The web is wound onto a winding roll at multiple locations located at The idea lies in positioning the actuating head for applying adhesive.

The structural idea is that an actuating head is provided in the device for the purpose of This arrangement The positioning is carried out by means of a lifting movement or pivoting lateral movement device extending across the machine. Thus, the insertion of the core shaft is done by means of a channel that can be moved, or each A core that is wound around a web roll, movable together with the support arm of the core chuck. Insertion of the core shaft is carried out by means of a device that makes two lifting or pivoting movements each time. Both of these things can be achieved.

The present invention is arranged in two rows 180° apart around the support roll and arranged horizontally in a qualitative manner. A central support for supporting multiple axially aligned web rolls in a row. Particularly suitable for use with paper winding machines that utilize rolls, the present invention also provides It allows the use of so-called central training of roles. Also, use a central support roll In this so-called duplex winding arrangement, the wafer being wound The roll pivots so that it moves outward as the diameter of the wound roll increases. each supported by a pair of spaced apart parallel arms that act It is. The end of the support arm is often called a tube or reel spool Equipped with a core chuck that is inserted into the end of the core, the core chuck holds the wound web roll. When the core is rotated by the rotating keyaki, the core is activated. core The chuck is powered by a DC motor attached to support arms on either side of the roll. It is driven by a motor like a motor. Such a drive arrangement is DE 380 It is known from 0703 Al. In addition, a core chuck with a power source is installed. Equipped with an adhesive applicator on each pivoted support arm, The adhesive applicator is attached to the inside of the outer edge of the web for each wound web roll. can always be positioned at the desired spacing on the side and directly on the wound web roll. As the diameter increases, it moves radially outward with the core axis. This allows the winding A circumferentially arranged line of adhesive is applied to a given web roll at a predetermined axis.
