Description

safety net manufacturing equipment

The present invention relates to an apparatus for manufacturing a safety net installed to prevent external exposure of dust generated at a construction site or to prevent safety accidents such as falling or falling, and more specifically, to a size required by unwinding from a provided roll of fabric. It relates to a safety net manufacturing device that can automatically cut to suit and perform processing and labeling, and maximize space utilization by minimizing equipment installation space.

In general, at the construction site of a building such as an apartment or building, a pedestrian or worker on the ground may be injured due to the fall of building materials, damage to others' property, or work at high altitude (高所作業; construction site, etc.) In order to prevent a safety accident due to a fall of a worker who does work from a high place, a safety net (fabric) is compulsorily installed and used on the outer wall of a building or the outside of a temporary structure.

In this way, the safety net installed on the temporary structure should be spread vertically or horizontally between the pipes of the temporary structure along the outer wall of the building and installed according to the site in a net method.

To this end, a band or ring is manually sewn along the rim of the safety net in the field, and the necessary cut of an appropriate width is manually provided to the site.

Although the size of safety nets currently installed at work sites varies, in general, rolls with fabrics of several tens to hundreds of meters are cut manually. is unwound from the fabric roll by a conventional fabric feeding roller, and two workers drag the unwound fabric on a wide table with a tape measure, straighten it according to the cut size, adjust the size, and then operate the circular rotating cutting blade directly. and cut by a conventional operation in the vertical direction to the length, and the operator directly operates a circular rotating cutting blade to cut by the conventional operation in the longitudinal direction. was attached using a zigzag zigzag, and the width of the long fabric was reduced so that the operator could transport the cut fabric, and transported to the next process and cut.

Therefore, in the prior art, there was a problem in that the work cost was delayed and the labor cost increased because the worker had to cut and sew the safety net one by one at the site to manufacture and install it.

In contrast, Patent Document 1 sews a vertical band to the safety net on the front side of the main body, sews a pair of horizontal bands on the rear side of the body, and at the same time cuts between both sides of the horizontal bands, so that vertical bands and horizontal bands are conveniently sewn to the safety net. By cutting between the two horizontal bands at the same time, we proposed a safety net manufacturing device for construction that can easily produce a safety net to the required size, shorten work time, increase production, and reduce labor costs.

However, there is no structure for applying all of the supplied fabric rolls of various widths, and no technology for cutting to the required width has been proposed, and the device of Patent Document 1 has a long overall length and requires sufficient space to install the equipment. Therefore, it can be seen that the space utilization decreases.

In other words, during the working time of three workers to produce a product, the worker has to produce the product without spare time, and the worker may be exposed to an unreasonable environment by the repeated repetitive motions of the worker.

Since the operator has to cut according to the specifications determined by the conventional process and the manual process by continuous manual work, there is a problem of quality deterioration due to the occurrence of defects in the product.

And, in the case of the conventional production method, since the fabric to be cut needs to be laid out and aligned on the table, a table of the size of the manufactured product is required to cut the fabric from several meters to several tens of meters, and the use of a wide working space reduces the space utilization. have.

A worker is exposed to an environment in which a safety accident may occur in the operation of a conventional facility, and there is a problem in that the efficiency of production decreases and the labor cost and manufacturing cost increase when the worker produces a product by the conventional process and the manual process.
