[0002]

2. Description of the Related Art As an application example of a long object holding device, a long object
Paper holding device for positioning the cut paper on the base
A paper cutting machine having the following will be described. For example, in the paper cutting machine shown in FIG. 7, one end of a rail 3 is supported on a base 1 by a support portion 2, and a paper pressing plate 4 is integrally attached to the rail 3 so as to be separated from and accessible to the rail 3. ing. To cut the cutting paper using this cutting machine, the other end of the rail 3 is lifted with the base of the rail 3 supported by the support portion 2 as a base point, and the cutting paper is placed on the base 1. While pressing down the rail 3 with the base as a base point, the cut paper placed on the base 1 is pressed by the paper pressing plate 4, and the lock mechanism 6 attached to the end of the rail 3 is fixed to the base 1. Is held by the locking member 7 to maintain the cut paper by the paper pressing plate 4, and then the slider 5 (see Japanese Utility Model Application No. 63-26776) fitted to the rail 3 is slid. The cutting paper is cut by a rotary blade mounted on the slider 5. Then, the cutting position of the cut paper is determined with reference to the edge of the paper holding plate 4, and the cutting paper is cut while rotating so that the side surface of the rotary blade contacts the edge of the paper holding plate 4.

[0003] In this paper cutting machine, there is not much problem when the number of cut sheets placed on the surface plate is small, but when the number of cut sheets is large, the rail is moved from one end of the rail as a base point. When the paper is pressed down, the paper holding plate also moves together with the rail, so that a large number of cut sheets are first pressed by the paper holding plate from the base end side of the rail, and the stacked cut paper Is shifted by the pressing force of the paper pressing plate. If the paper is cut in such a displaced state, the cut paper becomes irregular and cannot be cut to an accurate size. When the cutting paper is placed on the surface plate when positioning the cutting position of the cutting paper, the leading end of the paper holding plate together with the rail is raised from the base end of the rail. It is difficult to position the cutting position based on the edge, and before starting cutting, the rail must be pressed down several times to confirm the cutting position and then cut. Also, the stacked cut papers are displaced, and the cut papers become irregular, so that the cut paper cannot be cut to an accurate size.

In order to prevent the slippage of the cut sheet and facilitate the positioning of the cut position, all of the problems can be solved by moving the paper holding plate or the rail in a direction parallel to and perpendicular to the surface plate. You. When the rail can be moved in the vertical direction while keeping the rail parallel to the surface plate in this way, since the slider presses the rail at any position on the rail, any slider on the rail or paper holding plate can be used. The rails must be lowered vertically parallel to the platen even when pressing on a position, for example the end of the rail.

[0005]

The above description has been made with reference to a paper cutting machine as an example. However, even if an arbitrary position of a pressing member such as a rail of a paper cutting machine or a paper press is pressed, the entire press member is kept in a horizontal state. Long objects that can be held and vertically moved up and down
There is a device that is required to hold the object , and the present invention has been made in order to respond to this requirement, and provides a long object holding device that satisfies the requirement.

An embodiment of the present invention will be described below with reference to the drawings. The following description is made by taking an example in which the present invention is applied to a paper cutting machine. As shown in FIG. 3, between the rail support members 10 (movable members) of the paper cutting machine, a parallel arrangement described later is provided.
Actuating rod 15 and 16 of the two that are location is provided, the inclined surface 151 and the end portion of the operating rod 15 and 16 of the two
161 is formed, and the inclined surface 151 is the corner 1 of the rail support member 10.
04 abuts on (contact portion), the bottom edge of the inclined surface 161 is recessed hole 101 bored in the side surface of the rail support member 10 of the other operating rod 16 (those
Contact part) . This will be described in more detail.

In FIG. 1 showing the operating rod 16 side and FIG. 2 showing the operating rod 15 side, the inclined surfaces 161 and 162 of the operating rod 16 are inclined parallel to each other, while the inclined surface 151 of the operating rod 15 is inclined.
And 152 also have a parallel slope. The operating rods 15 and 16 are arranged such that the inclined surfaces 161 of the adjacent operating rod 16 and the inclined surface 151 of the operating rod 15 are turned upside down. The inclination directions of the 16 inclined surfaces 162 and the inclined surface 152 of the operating rod 15 are also upside down .

Each of the operating rods 15 and 16 is inserted into a guide hole 114 formed in an end 113 of a support member (hereinafter referred to as a base) 11, and a distal end of an inclined surface 161 of the operating rod 16 is formed with a concave hole.
In a state where plugged in between the ceiling portion of the edge of the rim and the guide hole 114 of the 101 of the bottom 105, the other inclined surface 162 abuts a corner 104 of the rail support member 10 (contact portion), whereas, The inclined surface 151 of the operating rod 15 contacts the corner 104 (contact portion) of the rail support member 10, and the tip of the other inclined surface 152 is connected to the edge of the bottom 105 of the concave hole 101 and the edge of the ceiling of the guide hole 114. It is in a state inserted between. FIG. 5 shows the inclined surface 162 inserted into the guide hole 114.
152 has appeared.

In FIG. 4, both ends of the rail 9 are supported by a rail support member 10.
Is mounted on the base 11 so as to be vertically movable along a guide surface 112 as shown by an arrow Y. Therefore, the rail 9 can be separated and approached in parallel to the cut sheet mounting surface 111 of the base 11 via the rail support member 10. Further, the rail 9 has two rail surfaces 901 and a paper pressing portion 902 (pressing member) is provided integrally. Reference numeral 8 denotes a slider which moves while being guided by the rail surface 901. The slider 8 is provided with a rotary blade (Japanese Utility Model Application No. 63-2).
No. 6776).

As shown in FIGS. 5 and 6, the rail support member 10 is constantly pushed up by the elastic force of a spring 12, and the pushing force is generated by a tongue piece 13 formed integrally with the rail support member 10. The rail support member 10 is stopped at a predetermined height and is stopped between the paper holding portion 902 and the cut paper placement surface 111 by being locked to the ceiling portion of the concave hole 113 formed in 11. A gap 14 into which the cut paper is inserted is formed.

Next, the assembly will be described. 1 and 2, the operating rods 15 and 16 are inserted into guide holes 114 formed in the base 11, and the rail support members 10 are fitted to guide surfaces 112 (FIG. 4) formed on the base 11. As a result, the inclined surface 152 of the operating rod 15 and the inclined surfaces 161 and 162 and 151 of the operating rod 16 have the positional relationship shown in FIGS. 1 and 2 with respect to the base 11 and the rail support member 10. Next, in FIG. 3, a positioning protrusion 102 provided on the rail support member 10 is inserted into a positioning hole 903 formed in the rail 9, and is fixed with a screw 17. As a result, the end surface of the rail 9 is fixed in a state of being in contact with the wall surface 106 of the rail support member 10, and the assembly is completed.

The operation of the embodiment constructed as described above will be described below. 1 and 2, the corners 104 of the rail support member 10 depressing the rail 9 moves the actuating rod 16 by pressing the inclined surface 162 in the direction of arrow X _1. Due to the movement of the operating rod 16, the tip of the inclined surface 161 becomes the bottom 105 of the concave hole 101.
Is pushed in a wedge shape between the bottom edge of the guide hole 114 and the ceiling edge of the guide hole 114, so that the other end of the rail 9 is pulled down along the inclined surface of the inclined surface 161. The lowering force of the inclined surface 161 causes the inclined surface 151 of the operating rod 15 to
Acts as a force to depress at 104 and moves the operating rod 15 by the arrow X ₂
It pushed like a wedge between the ceiling edge of the bottom edge and the guide hole 114 of the bottom 105 of the tip recessed hole 101 of the inclined surface 152 moves in the direction of (the direction opposite to the arrow X _1), the inclined surface 152 The other end of the rail 9 will be pulled down along the inclined surface.

The downward force acting on the end of the rail 9 due to the inclined surface 152 also simultaneously acts as a downward force due to the angle 104 of the rail support member 10 on the inclined surface 162 of the operating rod 16. Due to such an organic relationship between the operating rods 15 and 16, any part of the rail 9, for example, one end of the rail 9 (rail support member 10) may be pushed down to operate the operating rods 15 and 16.
Move in the X ₁ X ₂ direction, and the other end of the rail 9 is also lowered by the same amount, so that both ends of the rail 9 always descend by the same distance, and the rail 9 does not shift with respect to the base 11. It descends in the direction perpendicular to the paper placing surface 111.

Thus, even if the slider 8 shown in FIG. 4 is slid and a desired position of the rail 9 is pushed down, the rail 9 is always pushed down in parallel to the paper placing surface 111 of the base 11. Therefore, by setting a cut sheet in the gap portion 14 and cutting the rail 9 while pushing down the rail 9 with the slider 8, the sheet pressing portion 90 formed integrally with the rail 9 is formed.
The vertical force is applied to the cut paper by 2 and the paper loading surface 111
Can be pressed and held.

Next, when the pressing force of the slider 8 is released after the cutting is completed, both ends of the rail 9 are pushed up by the elastic force of the spring 12. The inclined surfaces 161 and 152 inserted in a wedge shape between the edge of the bottom 105 of the concave hole 101 and the ceiling edge of the guide hole 114 by the pushing force of the spring 12
Pushed by the edge of 105, actuating rod 15 and 16 arrows X ₁
And the X ₂ to return to the state of the moved origin in the opposite direction.
Since both ends of the rail are supported by the rail support member 10 and are parallel to the paper placement surface 111, the paper holding portion 9
It is easy to determine the cutting position by the edge of 02, and the rail 9 moves in the vertical direction with respect to the paper mounting surface 111. Therefore, even if the rail 9 is pushed down to determine the cutting position, the paper mounting surface Since the paper placed on 111 will not be shifted,
Positioning of the cutting position can be performed accurately.
