Description

[Detailed description of the invention] This invention relates to a selvage machine for cutting off each edge of a synthetic resin board, for example.

Traditionally, in order to cut off each edge of an item, first
The article is moved along the conveyance path, and while the article is traveling, the ears on both sides of the article are cut off by cutting machines provided on both sides of the first conveyance path.

Next, the articles discharged from the first conveyance path are rotated 90 degrees on a flat surface, and then sent to the second conveyance path and run. The ears are cut off on both edges.

This method requires two conveyance paths and four cutting machines, which increases equipment costs, and
There was a problem with this being a large device with a large installation area.

In addition, it is necessary to have a large number of workers, as it requires workers to supply the items to the first conveyance path and the second conveyance path, and workers to process the items discharged from the second conveyance path. There were also problems that had to be solved.

This idea uses two cutting machines installed at one location to cut off the edges of each edge of the item.
The purpose is to solve the above-mentioned problems.

This device consists of a table, a pair of cutting machines installed on both sides of the table, and a feed plate installed on the table to move forward and backward in the direction of the cutting machines and rotate at a predetermined angle. Cut off the selvage on one side of the item using a cutting machine, then rotate the item 90 degrees as it moves, cut off the selvage on both edges of the item using both cutting machines, and then cut off the selvage on both edges of the item as it moves.
To provide a selvage cutting machine which is rotated by 90 degrees and cuts off the selvage on the other side of an article using one cutting machine.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, 1 is a table, and a pair of cutting machines 2 and 3 are provided on both sides of the table 1.

The above-mentioned cutting machines 2 and 3 are of a type in which the cutting blades are lowered toward the blade receiver, and the facing interval between the cutting blades of both cutting machines 2 and 3 is the dimension between the edges of both ends of the item A. Adjust freely to match (this is done by loosening the fasteners, sliding the cutting machine on the seat plate, and then tightening the fasteners after adjustment)
It is becoming possible to do so.

Furthermore, a through hole 4 is provided between both side edges of the center of the table 1, with the upper and lower surfaces of the table 1 being open.

Further, below the through hole 4, a slider 5 is provided which reciprocates within a predetermined range between the two cutting machines 2 and 3.

The slider 5 is guided by two parallel shafts 6, and a cylinder 7 is attached to the slider 5.
The piston shafts of the cylinder 7 are connected to each other so that the cylinder 7 can be slid back and forth within a predetermined range by the forward and backward movements of the cylinder 7.

Furthermore, an intermittent rotation drive device 9 is provided on the slider 5 to drive the rotation shaft 8 at a predetermined angle in one direction.

The intermittent rotation drive device 9 uses a pawl and ratchet driven by a cam, a gear, a Geneva stop, or the like.

Furthermore, a feed plate 10 is provided at the upper end of the rotating shaft 8 and is fitted into the through hole 4 and whose upper surface is substantially flush with the upper surface of the table 1.

Further, a horizontal swing arm 11 having a pivot point at the end is provided directly above the table 1, and a slider 16 that slides along the longitudinal direction of the swing arm 11 is provided at the tip of the swing arm 11. There is.

Further, the slider 16 is provided with an elevating body 13 that descends due to the expansion action of the cylinder 12, and a freely rotating pressurizing plate 14 that presses the article A against the feed plate 10 is provided below the elevating body 13.

In the illustrated case, a post 15 is provided outside one end of the table 1, and the end of the swing arm 11 is attached to the post 15 so as to freely rotate, but it may also be attached to a cutting machine or the like.

The slider 16 has two parallel cylindrical bodies 17 attached to the distal end of the swing arm 11, and a shaft 18 extending from the slider 16 passes through the cylindrical bodies 17 to guide the slider 16.

The ear cutting machine according to this invention has the above-mentioned configuration. Next, the method for cutting off ears will be explained. First, a plate-shaped article A such as a synthetic resin plate is fed onto a table 1 by an operator. together with one cutting machine 2
Insert one side edge of the item A into the container.

However, when the switch is turned on, cylinder 12
The elevating body 13 is lowered by the elongation action, and the article is sandwiched between the feed plate 10 and the pressure plate 14.

Next, the operation of one of the cutting machines 2 is started, and the edge of one side of the item A is cut off by the cutting blade 2' which descends.

After cutting off the ears, the cutting blade 2' of one of the cutting machines 2 is raised and the operation is stopped.

Thereafter, the slider 5 is slid in the direction of the remaining cutting machine 3 by the contraction action of the cylinder 7, and the item A is slid on the table 1, and the feed plate 10 is moved together with the rotating shaft 8 by the operation of the intermittent rotation drive device 9. Rotate 90 degrees.

At this time, the item A is connected to the feeder 10 and the pressure plate 1.
4, rotate the item A by 90 degrees and insert both ends of the item A into the cutting machines 2 and 3.

Therefore, after the rotation of item A is completed, both cutting machines 2,
Start operation 3 and lower the cutting blades 2' and 3',
The edges of both ends of the item A are cut off by the cutting blades 2' and 3'.

When the cutting blades 2' and 3' have finished rising, the intermittent rotation drive device 9 starts operating to rotate the item A by 90 degrees, and the slider 5 is moved toward one of the cutting machines 2 by the extension action of the cylinder 7. At the same time, the item A is moved, and the other side edge of the item A is fed into one of the cutting machines 2.

After that, one of the cutting machines 2 is started to operate, and the lowering cutting blade 2' cuts off the edge on the other side.

After the ears are cut off, the pressure plate 14 is raised by the contraction of the cylinder 12, and the item A is taken out.

Furthermore, even if item A is a polygon other than a square,
The edges of each edge can be cut off by changing the rotation angle of the intermittent rotation drive device 9.

As described above, according to the cutting machine according to this invention, a pair of cutting machines are arranged on both sides of the table,
In addition, the feeder fitted into the through-hole of the table,
An intermittent rotation drive device rotates a predetermined angle in one direction, and a slider that slides in the direction of the cutting machine reciprocates, and a slider that slides in the longitudinal direction of the swing arm is provided at the tip of the swing arm. There is a pressure plate that moves up and down, so when the product is fed onto the table and one side of the product is fed into one cutting machine, the other cutting machine cuts off the edge of one side of the product, and then the product is cut off. can be rotated to cut off the ears on both ends of the item using both cutting machines, and the item can be further rotated so that one cutting machine can cut off the ears on the other side of the item.

Therefore, the edges of each edge of the article can be cut off efficiently, and a large installation area is not required.

Moreover, the number of workers can also be reduced.
