2. Description of the Related Art Conventionally, a tick sheet is provided on the floor of a chick-raising cage formed in a lattice shape so that the legs of the chick do not fall down from the gap of the lattice and the blades do not get caught on the lattice. I have.

The tic sheet is mainly formed of a paper material or a synthetic resin material such as plastic, and has a number of small holes provided at appropriate intervals so that chick droppings fall under the chick-raising cage. Have been. The chicks are placed on the floor of the nestling cage until about two weeks after birth.

[0004] In the case of manufacturing the tic sheet, a plurality of cuts 2 are formed continuously in the sheet material 1 in a shape of the small hole by a predetermined cutting tool. After the end of the cutting operation, the joint 3 adjacent to the gap 2 between the cuts 2 is pressed off by a finger to form a small hole 4, thereby forming the tick sheet 5 (FIGS. 6 (1) and (2)).
reference).

[0005] As described above, the reason why the small holes 4 are not directly punched during the cutting operation is that if the small holes 4 are punched out by the cutting operation, the cutting blade moves up and down or the sheet material moves laterally. For example, a large number of circular chips are scattered, and cleaning work afterward is troublesome, and the cutting chips are caught between the cutting blade and the sheet material, so that accurate cutting operation cannot be performed.

[0006]

In the conventional method of manufacturing a tic sheet, as described above, after the cutting operation is completed, a joint 3 adjacent between the cuts 2 is pressed with a finger to cut a large number of tic sheets. Since the small hole 4 is formed, the operation is complicated and the operation efficiency is extremely low.

Therefore, the conventional method of manufacturing a tick sheet has a problem that must be solved in order to efficiently punch out a large number of small holes.

[0008]

As a specific means for solving the problems of the prior art, the present invention is characterized in that a plurality of small holes are punched out in an aligned state by a cylindrical punching blade. A tic sheet is provided.

[0009] Further, a cutting device comprising a pressing plate having a plurality of cylindrical punching blades, elastic means provided near the punching blade, and a cradle located below the pressing plate is used, Place multiple stacked sheets on the cradle,
Another object of the present invention is to provide a method for manufacturing a tick sheet, characterized in that the pressing plate is lowered and a small hole is punched out by a punching blade while leaving a lowermost sheet material.

The elastic means may be a sheet-like elastic material provided on a pressing plate, and at least the elastic means provided in the punching blade may be a spring member. It was done.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. First, in FIG. 1, reference numeral 11 denotes a chick-raising cage in a poultry house of a poultry farm. The chick-raising cage 11 is formed in a lattice shape by a large number of wire members 11a in a horizontal direction and a vertical direction.

On the floor of the chick-raising cage 11,
The tic sheet 12 is provided so that the chick's legs do not fall down from the gap of the wire member 11a and the blades do not get caught on the lattice.

The tic sheet 12 is mainly formed of a thick paper material or a synthetic resin material such as plastic, and has a predetermined area for covering the floor of the chick cage 11. Further, the tic sheet 12 is provided with a number of small holes 13 so that various garbage such as bird droppings and hair growth may fall downward.

The plurality of small holes 13 are formed in an aligned state by a cylindrical punching blade described later.

Next, an apparatus for manufacturing the tick sheet 12 will be described. FIG. 2 shows a sheet material 1 made of paper.
2a shows a cutting device 14 for punching a large number of small holes 13. This cutting device 14 includes a pressing plate 16 having a plurality of cylindrical punching blades 15, and a receiving table 17 located below the pressing plate 16. It is composed of

The pressing plate 16 has a predetermined width and length, and a drive unit such as a motor or a hydraulic device (not shown) is provided at an upper portion thereof. The pressing plate 16 is configured to move up and down every predetermined time, for example, every several seconds by turning on an operation switch (not shown).

A plate-like support plate 15a is provided below the pressing plate 16, and a cylindrical punching blade 15 is provided below the support plate 15a at a predetermined interval. A plurality is provided. Note that the punching blade 15 is not necessarily limited to a cylindrical shape, and may be formed to have an appropriate punching shape such as an elliptical shape or a polygonal shape in some cases.

Further, a support plate 15 is provided near the punching blade 15.
Elastic means 18 is provided along the lower part of a.

The elastic means 18 is made of, for example, a rubber material having a sheet-like elasticity, and is formed to a thickness about the length of the punching blade 15. And the elastic means 18
Are disposed so that the punching blade 15 is substantially buried.

The receiving base 17 is formed of, for example, an iron plate, has a width substantially corresponding to the pressing plate 16 and a predetermined length, and has a predetermined width.

Next, a method of manufacturing the tic sheet 12 using the above-described cutting device 14 will be described.
First, as shown in FIG. 2, a plurality of paper sheets 12 a of about 0.3 to 2 mm, for example, about five sheets are stacked and placed on the receiving table 17. At this time, as the lowermost sheet material 12b, a mount having a different thickness or material from the other sheet materials 12a may be used.

When the operation switch of the cutting device 14 is turned on, as shown in FIG. 3, the pressing plate 16 is lowered, and the punching blade 15 removes each of the stacked sheet materials 12a. Punch out.

At this time, the lower end of the punching blade 15 is pressed by a pressing plate so as to punch out a small hole 13 in each sheet material 12a except for one sheet material 12b at the bottom of the stacked sheet materials 12a. The descending length of 16 has been adjusted.

As described above, since the punching blade 15 does not punch out only the lowermost sheet material 12b, even if the sheet material 12a overlapped during each punching operation process is laterally moved or lifted, The circular cutting waste 12c does not fall from below the material 12a.
As described above, when the punching shape of the punching blade 15 is set to be an elliptical shape, a polygonal shape, or the like, the cutting waste 12
It goes without saying that c is also elliptical or polygonal.

Further, when the pressing plate 16 is in the lowered state, the elastic means 18 presses the sheet material 12a, and the elastic means 18 is in a compressed state.

When the pressing plate 16 rises, the cutting waste 12c which is in contact with the inner peripheral surface of the punching blade 15 with a predetermined frictional force tends to lift up together with the punching blade 15, The elastic means 18 in the compressed state expands the cutting waste 12c and pushes it down against the frictional force.

Therefore, when the punching blade 15 is raised, as shown in FIG. 4, the cutting waste 12c remains in the sheet material 12a, so that the cutting waste 12c is scattered on the work table during the work. No punching blade 15 and sheet material 12a
This does not cause the inconvenience that the cutting waste 12c is caught between them.

When the pressing plate 16 is raised (FIG. 4), the sheet material 12a is moved by a predetermined length in the direction of arrow A by a predetermined sheet material feeding mechanism (not shown), and the above operation is performed. By repeating sequentially, a large number of small holes 13 are punched in an aligned state in the superposed sheet material 12a.

After the punching operation is completed, the stacked sheet materials 12a are moved to a predetermined garbage disposal place, and the sheet materials 12a are turned upside down. And the manufacture of the tick sheet 12 is completed.

The lowermost sheet material 12b in which the small holes 13 have not been punched out may be obtained by combining a plurality of sheets and then superimposing them again and punching out the small holes 13 as described above. If the sheet material is not wasted.

Next, another embodiment of the cutting device 14 will be described. In the other embodiments, the same parts as those in the above embodiment are denoted by the same reference numerals, and the details are omitted. As shown in FIG. 5, a cutting device 19 of another embodiment has a spring member 20 provided in a punching blade 15.

When the pressing plate 16 is lowered, the spring member 20 presses the sheet material 12a, and the spring member 20 is in a compressed state.

Next, when the pressing plate 16 rises, the punching blade 1
The cutting waste 12c that is in contact with the inner peripheral surface of 5 by a predetermined frictional force tries to lift up together with the punching blade 15,
The spring member 20 in a compressed state expands the cutting waste 12c and pushes it down against the frictional force.

Therefore, when the punching blade 15 is raised, the cutting waste 12c remains in the sheet material 12a, so that the cutting waste is not scattered on the work table or the like during the work.
There is no inconvenience that the cutting waste 12c is caught between the punching blade 15 and the sheet material 12a.

Although the present invention has been described with respect to a tic sheet and a method for producing a tic sheet, the use of the sheet is not necessarily limited to the tic sheet, and the sheet used for various other uses is not limited to the tic sheet. Of course, it can be applied to

[0036]

As described above, the tic sheet according to the present invention is formed by punching a plurality of small holes in an aligned state with a cylindrical punching blade, so that many small holes are directly formed in the sheet material. Since punching is performed, there is no need to perform a complicated drilling operation after the cutting operation as in the conventional example, and an excellent effect that the efficiency of the manufacturing operation is high is exhibited.

Further, in the method for producing a tick sheet according to the present invention, a pressing plate having a plurality of cylindrical punching blades, an elastic means provided near the punching blade, and a pressing plate located below the pressing plate. Using a cutting device consisting of a pedestal, place a plurality of stacked sheet materials on the pedestal, lower the pressing plate and leave a small hole with a punching blade leaving the lowermost sheet material. By punching, in particular, by providing elastic means in the vicinity of the punching blade of the cutting device, immediately after the punching blade descends and punches the sheet material, a predetermined friction is applied to the inner peripheral surface of the punching blade. The cutting waste coming into contact with the force tends to be lifted together with the rise of the punching blade, but the elastic waste expands and pushes the cutting waste, so that the cutting waste remains in the sheet material. Therefore, there is an excellent effect that the cutting waste is not scattered on the work table or the like during the operation, and the disadvantage that the cutting waste is not sandwiched between the punching blade and the sheet material does not occur.

Further, the punching blade punches out the small holes while leaving the lowermost sheet material, so that the sheet material can be moved from side to side or lifted during each punching operation step, so that the circular shape is formed from below the sheet material. No cutting chips will fall. Therefore, in combination with the use of the cutting device provided with the elastic means in the vicinity of the punching blade, there is an excellent effect that the cutting waste is not scattered on the work table or the like.

Since the elastic means is a sheet-like elastic material provided on the pressing plate, immediately after the punching blade descends and punches the sheet material, it is lifted together with the rise of the punching blade. Since the sheet-like elastic material expands and pushes down the circular cutting waste to be shaved and the sheet material in the vicinity of the cutting waste, the cutting waste remains in the sheet material, and the cutting waste is placed on the work table during the operation. It has an excellent effect of not being scattered.

Furthermore, by using at least a spring member for the elastic means provided in the punching blade, immediately after the punching blade descends and punches out the sheet material, the lifting together with the lifting of the punching blade is performed. Since the spring member pushes down the circular cutting waste to be cut, the cutting waste remains in the sheet material, and there is an excellent effect that the cutting waste is not scattered on the work table or the like during the operation.
