Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plaster sheet regular cutting device capable of continuously cutting a long plaster sheet into a convenient size.

Conventional technology: Compress therapy such as plaster is used for sprain, neuralgia, and sarcomatous wounds. This plaster is coated with an ointment on one side of a long fabric, a cover film is attached to the upper surface of this ointment to form a plaster sheet, and this plaster sheet is cut into a size convenient for use. It was

Various devices are disclosed for cutting this plaster sheet, but if one example is shown, a long rolled plaster sheet is fed to the cutting device via, for example, a line tuning device, and this plaster sheet is initially As shown in FIG. 7, a plurality of annular projections (61) protruding at equal intervals from the axial direction of the creasing roller (60) are used to perform creasing in the longitudinal direction, and the center of each streak The slitter unit cuts vertically. Next, the band-shaped plaster sheet is creased by another creasing roller, that is, a plurality of parallel projections protruding from the shaft center at an equal angle position, and the center of the streak is horizontally cut by a rotary cutter. The plaster, which has been cut into individual pieces, is transferred to the subsequent step.

Problems to be Solved by the Invention: When scoring the plaster sheet vertically and horizontally with each creasing roller by the above cutting device, as shown in FIG.
Since the cross-sectional shape of the protrusion provided in parallel with the (61) and the axial direction is a shape having an upright portion (62) at a right angle to the plaster sheet (41), the plaster pressed by the annular protrusion (61). The ointment (43) of the sheet (41) flows into the vicinity of the upright portion (62) of the protrusion (61) and rises, and in this state, the center of the muscle is vertically cut by a slitter unit. Next, the plaster sheet ointment pressed by the parallel protrusions protruding from another creasing roller flowed to the vicinity of the upright portions of the protrusions and was in a raised state in the same manner as above. Cross-cut with. Then, when the plaster sheet is pressed by the protrusions provided in parallel, the ointment also rises in the vicinity of the upright portion of the protrusion and some of the ointment protrudes from the cut end of the vertically cut plaster sheet. Also, the amount of ointment at the corners of the vertical and horizontal stripes is larger than that of other parts, and this ointment may stick out from the cut end of the plaster sheet and stick to the blade of the rotary cutter. The cutting ability was sometimes reduced. Then, in the plasters that are stacked in a bag of several sheets, the salve of the raised portion protrudes from the end of the plaster and the salves stick to each other due to the passage of time and the weight accumulated. Therefore, it takes a lot of time to separate each of the plasters when used, and when the separated plaster is used, there is a problem that the protruding ointment adheres to the underwear or clothes and is soiled.

In addition, the above cutting device performs scoring in the longitudinal direction of the plaster sheet with the annular projection of the creasing roller, and vertically cuts the center of this streak with a slitter unit, and a strip-shaped plaster sheet formed by cutting is provided separately. The parallel protrusions of the attachment roller make creases at right angles to the longitudinal direction, and the center of the creases is transversely cut by a rotary cutter. Therefore, it is inevitable that the work process from creasing to standard cutting becomes long and the device itself becomes large. Further, the relatively flexible plaster sheet often has a problem in that it is difficult to cut into a regular shape due to the improper timing of feeding the sheet to the cutter, resulting in many problems such as producing defective products.

Means for Solving the Problems: The present invention has been made to solve the above-mentioned problems, and it is possible to perform vertical and horizontal creasing of plaster sheets simultaneously with one ridge roller, The cutting device could be miniaturized by installing the slitter unit and the rotary cutter as close to the creasing roller as possible.

That is, in a continuous cutting device that cuts a long plaster sheet fed by appropriate means into a required shape and dimension, a ridge roller having a required diameter is provided at the center of the upper part of the base, and the surface of the ridge roller is a shaft. A plurality of annular protrusions are provided at equal intervals at right angles to the center direction, and a plurality of parallel protrusions are provided at equal angular positions from the axial center so as to be orthogonal to the annular protrusion.
The cross-sectional shape of each of the protrusions is a narrow top side and is formed into a sloping slope from both edges of the top side. A receiving roller for contacting and rotating with the protrusion roller is provided, and the protrusion roller is provided in the vicinity of the protrusion roller. Has a configuration in which a slitter unit having a required number of rotary blades in parallel, a rotary cutter having oblique blades, and a discharge conveyor are sequentially arranged.

On the surface of the ridge roller, the annular protrusion is the same as above, and a plurality of parallel protrusions provided at equal angular positions from the axis are provided orthogonal to the annular protrusion, and the parallel protrusion has a narrow cross-sectional shape. It may have a slight upright portion from the one edge of the apex toward the axis at the apex of the apex, with a gentle slope from the end of the upright portion and a gentle slope from the other edge, The mechanism arranged at the rear is similar to the above.

The distance between the center lines of the parallel protrusions provided at the equiangular position from the axis of each protrusion roller is equal to the length of one side of the plaster obtained by cutting the plaster sheet. Is the same as the length of the other side of the plaster, and the plaster produced by cutting the plaster sheet with a cutting device equipped with this ridge roller has no ointment protruding from the end of the plaster. It can be easy to use.

Action of the Invention: The creasing of the plaster sheet to the plaster sheet by the regular cutting device of the present invention was performed by pressing the cover film side of the plaster sheet with each apex and each inclined surface of the ridge roller, and with the apex. Part of the ointment flows to the other part and disappears, but it becomes minute. At the same time, the ointment pressed by the inclined surface and the ointment have an average flow distribution within a range that does not hinder the plaster ointment coating thickness while maintaining a gentle gradient from the four edges of the top edge along the inclined surface. To be done. Then, the center of the vertical and horizontal lines of the plaster sheet made by scoring is cut by a slitter unit and a rotary cutter, but at this time the ointment flows into the line,
It does not stick out from the cutting edge of the plaster sheet and can be cut to the correct size. That is, the plaster can be made equal to the distance between the center lines of the top sides of the annular protrusions and the distance between the center lines of the top sides of the parallel protrusions. In this way, the plasters obtained by cutting the plaster sheets into individual pieces are stacked, and the ointment does not stick out from the peripheral edge of the plaster even after a long time has passed.

Further, since the plaster sheet can be creased simultaneously in the vertical and horizontal directions, it becomes possible to dispose the slitter unit and the rotary cutter in the vicinity of the creasing roller. It can be cut to the desired size without slipping.
