Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to web handling apparatus, and more particularly to an apparatus for handling webs fed to a splicing station.

the web into an article, e.g. an article of elongated plastic;
In the use of a web from a feed roll that is fed to a production machine for making or forming, the trailing edge of the web fed from the roll can be removed from another roll without interrupting machine production. It is necessary to splice the ends of the webs used. When it comes to layered joint work!
, and relative to the web from the first roll such that the leading edge of the web from the new supply roll is located adjacent to the trailing edge of the web from the first roll that is feeding the web. Preferably, they are moved in an overlying relationship.

The object of the present invention is therefore to overcome: on the same side of the web that is being fed to the first station for splicing,
It is an object of the present invention to provide a web handling device for feeding the leading end of the web from a new roll; the device is simple, reliable, and does not cause interruptions in the web being fed to the production machine.

A web handling apparatus embodying the present invention includes a first roll support supporting a web roll for rotation about a horizontal axis and a first roll support extending longitudinally from the first web roll generally parallel to the first web roll. A first roll support supporting the entire web roll on spaced apart horizontal axes, and a splicing joint. The first roll support is aligned with the splicing station and the web from the first roll moves across the splicing station. /pairs of swivel bars are provided, seven of the swivel bars are positioned such that their axes make an acute angle with the longitudinal axis of the web coming from the second roll; converting the direction and moving it laterally towards the path of the web from the first roll;
The second pivot bar has an axis that is at an acute angle with respect to the longitudinal axis of the web coming from the first roll, and is configured to receive the web from the first roll and to change the direction of the web.
The web from the second roll then moves half way in the direction of the longitudinal axis of the web from the first roll towards a splicing station. The second pivot bar is pivoted on a vertical axis and is movable vertically along the vertical axis, such that the second bar moves the first web to the splicing station. As the first web moves from a position below the first web, it can be moved by pivoting the vertical axis swivel and vertically upwardly, and then pivoting the vertical axis swivel to move the vertical axis swivel. The i.g. is in a position overlying the first web as it moves toward the splicing station. This is the first web,
The web from the first roll is moved to a splicing station in overlying relation to the web from the first roll for overlying and splicing to the first web.

Referring to FIGS. 1 and 2, a web handling apparatus embodying the present invention feeds webs A and B horizontally from supply rolls 10 and/or, respectively, to a splicing station S.
Applied to selectively guide.

As shown in Figures 1 and 2, the supply roll 10 and/or are rotatably mounted on a stand /2.
, is mounted on a stand for rotation about concentric horizontal axes of /g. In the supply roll 10, the web A is guided between an inlet roller/j and an outlet roller/b,
It is aligned with the splicing station so that it is fed across the splicing station S. The web traveling across the station S then passes through a storage synutem or festoon of well-known construction and is sniffed so that the feed of the web is passed to the production machine/etc. is accumulated before. The hanging device/7 serves to accumulate the length of the web;
Any interruption in movement at the splicing station to allow for splicing does not impede production.

In order to feed the web Bi production machine and also move it across the splicing station, a horizontal cylindrical pivot bar 2.20 is located on the frame, 2/ supporting the splicing device. ing. The pivoting bar 79, whose axis is located at an angle to the longitudinal axis, serves to change the direction of the web B and to guide it through the guide rollers, 2.2. , the web B moves laterally. Swivel bar, 2
0 is normally positioned so that its axis is parallel to the par 79 and redirects the web B, which then passes through the splicing station st to the sag or storage device. move in one longitudinal direction.

As the web B is fed across the splicing station, the upper surface of the guiding pars .
(Fig. 1).

As web B is being fed, web A is manually passed through guide rollers/3 to splice the leading edge of web A from a new roll onto the trailing edge of web B. is pressed onto the top surface of web B, where it is in position to be spliced onto the top surface of web B.

When web A is fed through the splicing station S to the production machine and it is desired to bring the leading edge of web B into position for splicing, the device operates the pivot bar, ! 0 to a new position above the moving web A. This is accomplished by mounting the pivoting par, 20, on the shaft 2g for vertical movement along the axis of the shaft 2g and horizontal oscillatory movement about the axis of the shaft 2g. Lock Bin-2J-(
(Figure 2) typically extends through the opening in the swing bracket, 2θ, and the fixed bracket on the frame, thus holding it in the normal position shown in Figure 2. When web A moves across splicing station S and it is desired to bring the leading edge of web B from a new supply roll to the splicing position,
The lock bin is removed and the swing par, 20, is swung to the dashed line position shown in FIG. 2, that is, to the solid line position shown in FIGS. Returned and thus the lock bin 2 night bracket! Fixed bracket on the frame through the eye of the eye! It can be reinserted into the opening in 7. Web B can then be manually directed over the turning par 19.20f, so that the leading edge of web B is guided onto the upper surface of web A being fed so that a splice can be made. 3rd, Figure A A+ B). After the splicing is completed, the pivoting par, 20, is lowered to its normal position and the web B is subsequently fed to the production machine.

In order to facilitate the vertical movement of the swing par 20, an actuator is provided on the frame and includes an actuator arm, 29, which engages the lower end of the shaft 2≠ and is adapted to meet the demands of the cycle. The turning par, 20, is raised or lowered accordingly.

As shown in FIG. 1, the hanging device consists of rollers 30 mounted on a plurality of frames and rollers 3/ mounted on a par 32 pivoted on the frame, 2/. Accumulated web roller 30.3/f
Then, it passes over the fixed guide roller 33 and the nupling square load roller 3 t'i and is sent to the production machine. During the splicing operation, when the web being fed across the splicing station is interrupted, cylinder 3j progressively shakes the par in a counterclockwise direction as seen in Figure 1, causing the weds production machine to sag. The operation of the machine is thus not interrupted. Once the splicing operation is completed, the cylinder 3j is actuated to return the par 3.2 to the initial solid line position in Figure 1 and to release (storage) new web for use in the subsequent splicing operation. can be accumulated.

An air source (not shown) provides a rotating par/9. ．． Air is supplied to the openings in the surface of 20 to facilitate the passage of web B over the surface of the swirling par.

FIG. 7 shows a schematic diagram of the control circuit for the system. To begin splicing web B to the trailing end of web A, the operator manually moves the pivot par, 2Of, from its normal working position to a position where its axis extends parallel to web A. (Figures 3A and 3B). The operator then moved the actuator arm 3 to the raised position by moving the ffA Yahar 7''37 7-ial control to supply air to the vertically oriented actuator 2g, thus turning the 'fr: Raise.The operator then manually returns the swivel cooler web A to a position lying above it, and then manually moves the web B onto the fixed and movable swivel S-/9, 20. point (
3, Otsu A, Figure 68).

When the splicing is performed, the operator operates a control that operates the rev 39, supplying air to a valve that controls the operation of the spoolicer (splicing device) S, shown diagrammatically. /S) The rev 39 controls the exhaust air from the droop-intensive cylinder 3j, which causes the stored web A k to be progressively transferred to the production machine while the splicing is being performed. . The timer≠/ provides a time delay and after a predetermined period, fluid is supplied to return the cylinder 3j to its initial position. At the lap splicing station, after the lap splicing is performed manually and automatically 4h*, the -=r nial control 3 is returned to its initial position and the actuator arm! The web is automatically retracted and lowered by 20'x, allowing normal operation of the feed web B to the production machine.

to allow webs from separate rolls to be fed across the splicing station, and in which case the leading edge of the web from the new roll is used as the leading edge of the web from the roll that is feeding the web. It can be seen that a web handling device was provided which always feeds the same side stop of the web to the rear end.
