Abstract

PURPOSE:To secure cutting in a device tearing off and cutting the edge of a belt-like raw material by providing a curl removing roller, a roller moving mechanism, a pair of roller-like strainers, and a strainer operating mechanism between a separation point and a cutter. CONSTITUTION:The operation of a device is performed by curving the edge section 14 torn off from a raw material 11 with a curl removing roller 21 in the opposite direction to the winding direction of a separation roller 13 then pinching and pressing and correcting it in a straight line with a pair of roller- like strainers 25. Thereby, no curl is generated at the tip of the edge section 14, and it is reliably fed to a cutter 18. In setting, the curl removing roller 21 and the strainers 25 are operated to the setting position, and the edge section 14 separated from the separation roller 13 is inserted into the cutter 18 below in a straight line. Accordingly, the setting at the start of the operation is easy and reliable, and the edge section 14 can be reliably cut.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a system for incorporating into a cathode ray tube! ! The present invention relates to an edging device that is used in flat mask etching processes for dough masks, etc., and which strips and cuts edges provided in the length direction of a strip-shaped material.

[Technical background of the invention and its problems]

In the flat mask etching process for shadow masks, after a strip-shaped material is etched, unnecessary edges (half-etched portions) that occur on both sides of the material in the length direction are peeled off. As a edging device for this purpose, a structure shown in FIGS. 3 and 4 has conventionally been used.

That is, in the figure, reference numeral 11 denotes a band-shaped material made of an iron plate, which is moved in the horizontal direction by conveyance rollers 12. 13
A separation roller is used to peel off the edges 14 that are continuously formed along the length on both sides of the material 11 from the material 11. The edge 14 peeled off by the separation roller 13 is guided downward by guide plates 15a and 15b (not shown in FIG. 4). Reference numeral 16 denotes a driving roller, and two pressing rollers 17 are in pressure contact with the outer periphery of the lower part of the driving roller. It is guided to the right in the figure and wound in the same direction. The edge portion 14 wound and fed by the driving roller 16 and the pressing roller 17 is guided downward by a guide plate 15d, and cut into pieces by a horizontal cutter 18 located below.

However, in the above-mentioned conventional @ placement, the tip of the edge 14 sent from the driving roller 16 and the pressing roller 17 curls so as to wrap around the pressing roller 11 side. A phenomenon occurs in which the edge 14 does not reach the cutter 18 and the edge 14 accumulates at the entrance of the cutter 18.
Therefore, a problem arises in that the yield is reduced.

Also, during initial setting of operation, the edge 14 is connected to the drive IJ.
Since the portion between the o-roller 16 and the pressing roller 17 has to be bent significantly, the edge 14 often does not reach the cutter 18 and gets jammed in the middle. -Therefore, there are problems in that manual labor is required for setting and operability is poor. Furthermore, the structure? It also had the problem of being sloppy and having poor maintainability.

[Purpose of the invention]

It is an object of the present invention to provide an edging device in which the peeled edges reliably reach the cutter, the initial setting can be easily performed, and the yield, operability, and maintainability are improved. be.

[Summary of the invention]

The edging device according to the present invention includes a separating roller that downwardly strips an edge provided in the longitudinal direction from a strip-shaped material that is transferred in a horizontal direction; a cutter for cutting the edges; a decurling roller located below the material and behind the separation point of the separation roller in the direction of its movement, over which the stripped edge is passed around; and above the cutter. a pair of roller-shaped strainers located at the edge of the material that have passed through the curl removing roller and supplying the material toward the cutter; and a pair of roller-shaped strainers located at It is equipped with a curl removal roller moving mechanism that moves the roller, and a strainer operation mechanism that operates the pair of roller-shaped strainers to a setting state that releases the pinching pressure on the edge, and the curl removal roller prevents curling of the edge. By preventing this, the strainer reliably feeds the edge to a part of the cutter, and by setting the strainer to the specified setting state, the setting at the initial stage of operation can be performed easily and reliably. This is what I did.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, a strip-shaped material 11 made of an iron plate is transferred in the horizontal direction by a conveying roller 512 as in the past, and separated by separation rollers 13 provided on both sides of the material 11 in the longitudinal direction. The removed edge 14 is peeled off.

A curl removing row 21 is provided below the material 11 and behind the separation point 13a of the separation roller 13 (to the left in the figure) with respect to the direction of movement of the material 11. Reference numeral 22 denotes a moving mechanism for the curl removal roller 521, which uses a cylinder mechanism, for example, and moves the curl removal roller 21 to a setting position (indicated by a broken line) in front of the separation point 13a of the separation roller 13 (to the right in the figure). move it to This curl removing row 5
At the setting position 21, a guide plate 23a is provided along the vertical direction at the E section and the lower part.

23b is provided.

A pair of roller strainers 25 are installed above the cutter 18, pinch the edge 14 that has passed through the curl removal roller 21, and supply the strainer toward the cutter 18 below.

Reference numeral 26 denotes a strainer operation vi mechanism, which uses, for example, a cylinder mechanism, and operates the strainer 25 to a setting state (indicated by a broken line) in which the clamping pressure on the edge 14 is released. In addition, these strainer 25 and cutter 1
8, a guide plate 23C in the vertical direction is provided.

In the above configuration, the edge 14 peeled off from the material 11
is formed into a curve by the curl removal roller 21 in the opposite direction to the winding direction of the separation roller 13, and is further compressed by a pair of roller-shaped strainers 25 to straighten it into a straight shape.

Therefore, the tip of the edge 14 does not curl as in the conventional case, and the edge 14 is reliably supplied to the cutter 18. Further, during setting, both the curl removal roller 21 and the strainer 25 are operated to the setting position shown by the broken line, so that the edge 14 separated from the separation roller 13 is not exposed to any obstruction as shown by the broken line. It can be inserted in a straight line toward the cutter 18 below without moving. Therefore, setting is easier than in the conventional cutter having a large bend, and the edge 14 can be inserted and set into the cutter 18 reliably.

〔Effect of the invention〕

As described above, according to the present invention, the setting at the start of operation can be easily and reliably carried out, and during operation, curling does not occur at the cutter center unlike in the conventional case, and the edges can be cut reliably. It is possible to obtain a stable conveyance state of the material.
