Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a continuous press cutting method for cutting out mail carpet from a long raw carpet.

[Conventional technology and problems]

There is a method of cutting a carpet into a predetermined size from a long raw carpet, and a press cutting method, in which the carpet is cut out using a knife that moves up and down.

By the way, the former rotary knife cutting method can only cut the carpet material in one direction, so two steps are required: vertical and horizontal cutting, which is inefficient and increases the cutting cost. There is a problem that thermal changes occur in the carpet cutting area due to contact with the rotary blade during cutting, making it impossible to obtain high-quality cuts.

The latter press cutting method is superior to the rotary knife method in terms of cutting efficiency and straight grain of the gJ cutting edge because it can cut in the vertical and horizontal directions at the same time.

By the way, in the conventional press cutting method, the original carpet is cut into a predetermined size in advance and then cut out using blades arranged in a lattice frame shape, which results in loss around the carpet.

Due to its structure, the original carpet has ears on both sides, and the loss that occurs when removing these is unavoidable, but when cutting out a standard length carpet, there are 15 to 30 ears on both sides along the length of the original carpet. It is uneconomical because a loss occurs due to a change in the process, and this loss is completely wasted.

This invention has been made in view of the above-mentioned points, and provides a continuous press cutting method for carpet that can cut the carpet as it is and eliminate loss in the longitudinal direction. is the purpose.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention combines a vertical cutter and a horizontal cutter at the rear of a positioning stopper that receives the leading end of the carpet in the feeding direction on the pedestal, and abuts the stopper. A press knife mechanism that simultaneously cuts out several carpet tiles of a predetermined size from the carpet based on the tip of the carpet, and a carpet holding member located in the area surrounded by each knife of the knife mechanism are arranged so that the tip of the carpet is positioned. After contacting the stopper, the carpet is first pressed onto the pedestal at different timings in order from the presser section near the positioning stopper to the rear presser member, and the slack of the carpet on the cradle is removed from the rear of the press blade mechanism. Then, a press knife mechanism is used to cut out a large number of tile carpets from the carpet.

For CfN] When the leading edge of the raw carpet fed onto the pedestal comes into contact with the positioning stopper and stops, the press knife noodle tank and the carpet holding member descend, starting from the holding member closest to the positioning stopper to the rear. The carpet is pressed down to the holding part A in order at different times, and the slack in the carpet is released in order to the rear.Next, the blade mechanism cuts out the carpet based on the tip edge that has come into contact with the stopper, and cuts out multiple pieces of carpet. Form carpet tiles at the same time.

After cutting, the blade <4 and the presser member rise, and the positioning stopper escapes upwards, and the carpet tile is sent forward from the pedestal, and the leading edge of the carpet material fed onto the pedestal falls down. When it returns to the first position, it comes into contact with the stopper and stops, and the next cut is made.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, a base 1 is installed 88 at the bottom of a conveyance line that sends the raw carpet A, and the carpet A is supported by a pedestal 2 made of a rubber plate or interlocking resin plate laid on its upper surface. .

A positioning stopper 3 is disposed above the pedestal 2 at a position in front of the carpet A in the moving direction, and furthermore, a press blade mechanism 4 and a carpet holding part support 5 are disposed on the pedestal 2 at a position behind the stopper 8. is provided.

The positioning stopper 3 has its upper end attached to a horizontal shaft 7 supported by a frame 6 on the base 1, and is able to swing freely around the horizontal shaft 7, and is brought into contact with the carpeller (A) with a hanging layer shown by a solid line in FIG. When the surface 3a becomes vertical and the tip of the carpet carpet (A) that has been fed on the pedestal 2 comes into contact with it, the tip of the carpet is positioned 1' and rotates immediately to the front upper part of the line '4' in the figure. When the carpet is moved, the positioning with respect to the carpet A is released, and the carpet A is free to move forward.

The driving source for vertically swinging the positioning stopper 3 is
For example, a cylinder or the like can be used, and a switch 8.8 for detecting the tip of the car propeller A is attached to the contact i3a of the stopper 3 at a position near both ends.

The press knife mechanism 4 has a horizontal lifting plate 10 fixed to a lifting shaft → supported by a frame 6, and a vertical blade 11 and a horizontal blade 12 attached to the lower surface of the lifting plate 10 in a lattice frame shape. A cylinder 1 is formed and connected to the lower end of the lifting shaft 9.
By pulling down the lifting shaft 9 at step 3, the vertical and horizontal blades 11, 12 cut out the carpeller (A) on the pedestal 2.

In the case shown in the figure, the press knife mechanism 4 is an example in which a total of six carpet tiles are cut out at the same time, two rows of three, with the tip of the carpet tile (A) in contact with the positioning stopper 3 as a reference. The vertical blades 11 and three rows of horizontal blades 12 are combined in a frame shape, and the tip that abuts the stopper 3 is not cut and is used as one side of the tile carpet. It has a planar size sufficient to accommodate the

The carpet holding member 5 has vertical cutters 11 and horizontal cutters 1.
It is formed by a plate that fits in the area surrounded by spring 1.
4 is attached to the lower surface of the elevating plate 10 in a suspended manner.

When the elevating plate 10 is in the raised position as shown in FIG. The protruding portions decrease in order from items 5a to 5C toward the rear, and are lined up in a stepped manner in the front-rear direction.

Therefore, during the cutting process in which the press knife mechanism 4 descends F, the presser member 5 first presses the carpet A onto the pedestal 2, and then the knife mechanism 4 cuts out the car vera l-A.

Since each of the presser parts f-5 is arranged in a stepwise manner,
Those closest to the positioning stopper 3 53 to 5b, 6c
In order to press the carpet A in order, if the carpet A whose tip and end are in contact with the stopper 3 is sagging at the pedestal 2F, the slack is pushed back sequentially, and as a result, the cradle 2 Carpet A on top
As shown in Fig. 1, the slack A of the carpeller A is released to the rear end of the pedestal 2.
The press knife mechanism 4 allows cutting with high dimensional precision.

In addition, feeding of the raw carpet A to the pedestal 2 is done using a chain 2 or a belt conveyor, and ends before the pedestal 2.Although not shown in the figure, the pedestal 2 is equipped with a press cutter mechanism. A tile carpet feed roller and a take-out conveyor are provided in front of the pedestal 2 in a position that does not interfere with the cutting of the tile carpet, and this feed roller and conveyor are three times faster than the original carpet feed conveyor. After being driven, the carpet tile is quickly discharged from the pedestal 2 after cutting, and a gap is formed between it and the next leading edge of the original carpet A to allow the positioning stopper 3 to return to the detection position. ing.

The press cutting method of this invention has the above configuration,
With the positioning stopper 3 hanging down, the original carpet (A) is fed onto the pedestal 2, its tip touches the stopper 3, and when switch 6° (1 detects this), the feeding of the original carpet stops. do.

In this state, the cylinder 13 contracts and the elevating plate 1° is lowered by F, and the presser member 5 first presses the car peller (A) in order from the one closest to the stopper 3, and prevents the car pella (A) from sagging on the pedestal 2. In the pressed state, next press cutlery mechanism 4.
(Carpet) Cut A and cut out the carpet tile.

After cutting is completed, the stopper 3 rotates upward, the blade mechanism 4 and the presser foot 5 return to the raised position, and the tile carpet is discharged forward at high speed, and the next carpet carpet (A)
is fed onto the pedestal 2, comes into contact with the stopper 3 which has returned to the hanging position, and stops, and thereafter cutting is performed in the same process as described above.

- [Effects] As described above, according to the present invention, the press blade mechanism cuts out the raw carpet whose tip is in contact with the positioning stopper, so when cutting out tile carpet from the raw carpet, the tip It is possible to cut out continuously based on the standard, and there is no loss in the longitudinal direction of the raw carpet, which is economically advantageous.

Furthermore, since the presser foot presses the carpet in order from the one closest to the stopper, the carpet head does not sag on the pedestal, and the dimensional accuracy of the mail carpet can be greatly improved.
