Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material supporting device capable of supporting a printed or painted plate material without damaging the printed / painted surface, a magazine for accommodating the plate material, and a carrying rail. Etc. can be applied.

[0002]

2. Description of the Related Art Conventionally, for example, when printing or painting a relatively thin plate made of synthetic resin, a fixed number of plates are placed in a magazine having shelf-like support members on both sides as shown in FIG. Then, the process of storing and transporting to each processing step in the state of being stored in the magazine, taking out each plate material from the magazine, performing each processing, and again storing in the magazine and transporting, was carried out.

[0003]

However, as shown in FIG. 5, the shelf-shaped support member 31 for supporting the end portion of the plate material B in the magazine 30 is formed in a U-shape in longitudinal section. If the plate material B is relatively thin and the center portion of the plate material B supported at both ends in a horizontal state is bent by its own weight,
Since the lower surface of the plate material B contacts and is supported by the corners of the supporting member 31, there is a problem that the plate material or the printed / painted surface on the surface of the plate material is easily scratched when the magazine is transported.

The present invention has been made in view of the above points, and an object of the present invention is to provide a plate material supporting apparatus capable of supporting a plate material without damaging the end surface of the plate material.

[0005]

In order to achieve the above object, a plate material supporting device of the present invention is a plate material supporting device that horizontally supports a plate material by supporting both ends of the plate material by supporting members. In the supporting member of the above, a recess for inserting the end portion of the plate material is formed at a portion facing each other, and a supporting surface on the lower side of the recess is formed to be inclined downward, and the inclination angle of the supporting surface is Is formed to be larger than the bending angle at the time of supporting.

[0006]

In the supporting device having such a structure, the plate member is inserted into and supported by the recesses of the supporting member whose both ends are opposed to each other, but the supporting surface of the supporting member is downward. Since the plate material is formed to be inclined, and the inclination angle is formed to be larger than the bending angle at the time of supporting the plate material, the plate material is supported by applying only the lower corners of both ends to the inclined support surface of the support member. To be done. Therefore, as in the past,
The surface (upper surface or lower surface) of the end portion of the plate material does not hit the corner portion of the support member, and thus even if vibration or the like is applied, it is possible to prevent the end surface of the plate material from being scratched.

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

FIG. 1 shows a perspective view of a plate material magazine 1 to which a supporting device is applied, and FIG. 2 shows a sectional view of a plate material B housed in the magazine 1. The plate material B is made of, for example, a thin synthetic resin plate, and is printed or painted on both surfaces or the upper surface thereof, and is housed and conveyed in the magazine 1 in the printing process, the drying process, or the like.

The magazine 1 is formed in a box-like shape with a rectangular front frame 2 and a lower frame 3 connected by a plurality of vertical frames 4 and is open at the front and back sides, and has a pair of plate-shaped supports inside. The members 5, 6 are arranged vertically, facing each other. This support member 5, 6
Has a plurality of recesses 5a, 6a for inserting the ends of the plate material B, which are formed in a multi-stepped shape having a constant horizontal direction. The recesses 5a and 6b have a substantially triangular cross section, and in particular, the lower support surfaces 5b and 6b that support the ends of the plate material B are formed to be inclined downward. Further, the recesses 5a, 6a of the support members 5, 6 on both sides are arranged such that the facing recesses are at the same height position.

When both ends of the plate material B are supported in a horizontal state, the plate material B is thin so that it bends so that its central portion hangs down by its own weight. However, as shown in FIG. 2, the supporting surfaces 5 of the supporting members 5 and 6 are bent.
The inclination angle β of b and 6b is formed to be larger than the deflection angle α when the plate material B is supported.

Further, the support members 5 and 6 on both sides are movably arranged so that the distance between them, that is, the width for accommodating the plate material B can be changed. Two pairs of screw rods 7 having a right-hand screw and a left-hand screw are rotatably supported on the upper frame 2 and the lower frame 3, and these screw rods 7 are pierced at corresponding positions of the support members 5, 6. By screwing into the provided screw holes and rotating the two pairs of screw rods 7, it is possible to arbitrarily change the distance between the two side supporting members 5 and 6, that is, the storage width, and to store plate materials of different sizes.

At the front and rear ends of the magazine 1, rods 8 are vertically inserted into the upper frame 2 and the lower frame 3 in order to prevent the stored plate materials B from falling.

In the magazine 1 thus constructed, the rectangular thin plate material B is formed into the concave portions 5a, 6 of the respective steps of the supporting members 5, 6.
Both ends are supported by the supporting surfaces 5b and 6b.

At this time, the supporting surfaces 5b of the supporting members 5 and 6,
Since the inclination angle β of 6b is formed to be larger than the deflection angle α of the plate material B when it is supported, the plate material B is supported by being supported by the inclined support surfaces 5b and 6b only at the lower corners of its both ends. It

Therefore, unlike the prior art, the surface (upper surface or lower surface) of the end portion of the plate material does not hit the corner portion of the support member, and the surface of the end portion of the plate material is damaged even when vibration or the like is applied. Is prevented.

FIG. 3 shows another embodiment of the support member. Each support surface 15b of the support member 15 is formed so as to be inclined downward and have a convex curved surface.
The curvature of the convex curved surface is set to be substantially the same as the curvature of the plate material B at the time of supporting.

Thus, the supporting surface 15b having the convex curved surface
When the end portion of the plate material B is supported by, it is possible to reduce the lowering of the support position of the plate material B while supporting the corner portions of the plate material B. That is, when the support surface of the support member is tilted downward, the support position of the plate material B is lowered from the center of the recess, but the support surface 15b is formed into a convex curved surface, so that the support position is lowered. If the curvature of the convex curved surface is set to be substantially the same as the curvature of the plate material B at the time of supporting, the surface other than the corners of the plate material B will not contact the supporting surface 15b.

FIG. 4 shows a perspective view of a rail for carrying a plate material to which the supporting device of the present invention is applied. This rail 2
5, 26 are recesses 25a having a triangular cross section on one side surface of a square bar,
26a is formed in the longitudinal direction, and the recesses 25a and 26 are arranged so as to face each other at regular intervals. Further, similarly to the above, the support surface 2 formed below the recesses 25a and 26 is formed.
5b and 26b are formed so as to be inclined downward, and support surface 25
The inclination angles of b and 26b are formed to be larger than the bending angle of the plate material B when it is supported.

Even in such a transportation rail, since the inclination angles of the supporting surfaces 25b and 26b are formed to be larger than the bending angle of the plate material B when it is supported, the plate material B has lower corner portions at both ends thereof. Support surfaces 25b, 26b with only slant
Since the surface (upper surface or lower surface) other than the corners of the plate material does not hit the corners of the rail or the like, the plate material B can be favorably supported and transported without being damaged.

In addition to the above-mentioned magazines and transport rails, the supporting device of the present invention can also be used for a buffer device and a stock device for holding a plate material so as to horizontally support both ends of a thin and flexible plate material. You can
