Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a scrap container for a sheet stencil type marking device.

This sheet stencil type marking device is a sheet stencil with a predetermined mark content punched out and pressed onto the material to be treated such as a steel plate, and paint is sprayed from above. The marking work is performed continuously by feeding the sheet stencil and the sheet stencil at different angles from each other at right angles to each other.

This type of marking device therefore requires equipment for processing used sheet stencils.

Therefore, conventionally, as shown in FIGS. 1 to 3, a scrap container 23 has been used which is placed adjacent to the marking device 22 via a temporary storage section 21.

The temporary storage section 21 includes a box-shaped main body 24 whose surface that contacts the marking device 22 and the scrap container 23 and whose top surface are openings, and a first cylinder 2.
5, which rotates to open and close the top opening; and a push-in plate, which has approximately the same shape as the vertical cross section of the main body 24 and moves forward and backward by the drive of a second cylinder 27 installed on the floor. It consists of 28.

Then, leave the lid plate 26 in an open state,
Used sheet stencils 29 blown from the marking device 22 by a blower (not shown) are dropped into the main body 24 and accumulated. Sheet stencil 29 inside the main body 24
When 5 to 6 sheets of stencils are accumulated, the second cylinder 27 is extended and the pushing plate 28 is moved to the left, thereby pushing all the sheet stencils 29 in the main body 24 into the scrap container 23 side. At this time, in order to prevent the sheet stencil 29 from protruding outside the temporary storage portion 21, the above-mentioned pushing may be performed with the cover plate 26 closed.

The scrap container 23 is a box-shaped cart, and the side surface and bottom of the main body 30 on the side of the temporary storage section 21 are opened to form separate inlet ports 31 and discharge ports 32, each of which has a double door. 33,3
4 so that it can be opened and closed. Among these, the outer surface on both sides of the push-in opening 31 and the double door 3
First and second guide rails 35 and 36 are provided on both end surfaces of the first and second guide rails 35 and 34, and the first and second guide rails 35 and 36 are provided so as to be able to roll freely along each of the first and second guide rails 35 and 36, respectively.
Second guide members 37, 38 are provided. Further, while the first and second guide members 37 and 38 are connected by a connecting member 39 whose both ends are connected with a pin,
An eye bolt 40 is attached to the upper surface of the main body 30 to be used when suspending the main body 30.

Then, after lifting the scrap container 23 by suspending the first guide member 37 together with the eye bolt 40 by a crane, when the suspension force of the first guide member 37 is released, the double door 34 opens downward under its own weight and reverses. When closing the double door 34, the first guide member 37 is suspended and moved upward relative to the first guide rail 35.

Therefore, first, the scrap container 23 is directly connected to the temporary storage part 21 with the car empty and the double door 33 of the push-in port 31 open, and the sheet stencils 29 are accumulated and pushed in repeatedly as described above. , the sheet stencil 29 is accumulated in the body 30 in a compressed state to fill it.

Then, the scrap container 23 is placed in the temporary storage section 2.
After the scrap container 23 is separated from the container 1 and the double door 33 is closed, the scrap container 23 is transported by a crane to a predetermined discharge location as described above, the double door 34 is opened, and the sheet stencils 29 in a compressed and accumulated state are discharged. It was designed to do so.

However, in this scrap container 23, the first guide member 37 as well as the eye bolt 40
Since the discharge port 32 is opened and closed by suspending the sheet stencil 29 and operating the first guide member 37, a special hanger or a double crane is required for the discharge operation of the sheet stencil 29. Nakatsuta.

Further, since the discharge port 32 is formed by opening only the bottom surface of the main body 30, the compressed and accumulated elastic sheet stencil 29 forms an arch within the main body 30 when being discharged, and becomes unable to fall. It had disadvantages such as being prone to

The present invention was developed in view of the above-mentioned drawbacks of the conventional art, and while the inlet is formed on one side of the box shape, the outlet is formed continuously between the side and bottom of the box shape, which is different from the side. The side plate is formed to be open and is rotatably attached to the upper end of the other side, and the bottom plate is rotatably attached to the lower end of this side plate. By providing manual locking means for releasably locking the bottom plate and a discharge hanger installed slightly eccentrically from the center of the box-shaped ceiling surface, sheets can be handled and stacked using a normal single-layer crane. It is an object of the present invention to provide a scrap container for a sheet stencil type marking device that enables smooth discharge of stencils.

Next, the present invention will be explained with reference to the drawings which are one embodiment.

Figure 4 and below show a scrap container according to the present invention, in which one side of the box-shaped main body 1 of the box-shaped cart is opened to form a push-in port 2, and another side and the bottom are continuously opened. A discharge port 3 is formed by opening.

The push-in opening 2 has a shape in which a lower part projects outward from an upper part, and is configured to be openable and closable by a presser frame 4 rotatably attached to a horizontal axis at the upper end thereof. This presser frame 4 is made by combining pipes in a lattice shape and has an L-shaped cross section as a whole, and when the push-in port 2 is closed as shown in FIG.
It is formed so as to come into contact with the lower end of the push-in port 2 and to form a gap 5 at the upper end of the push-in port 2 . and,
Even if the sheet stencil pressed into the main body 1 in a compressed state protrudes outside the main body 1 due to its spring back, the protrusion is absorbed by the gap 5, and the protrusion is absorbed from above by the protrusion of the lower part of the insertion opening 2 and the presser frame 4. The presser foot prevents this protruding portion from collapsing onto the floor.

The discharge port 3 is formed by a side plate 6 rotatably attached to the upper end of the side plate 6 and a bottom plate 7 rotatably attached to the lower end of the side plate 6. There are two locking protrusions 8 on the end surface.
and two guide rollers 9 are provided so as to be rotatable about a support shaft parallel to the rotation center axis.

On the other hand, two hooks 10 are rotatably attached to the side surface of the main body 1, and the hooks 10 are connected to each other so as to be integrally operable by a first connecting rod 11 connected to each other by a pin. In addition, an L-shaped handle 13 is rotatably mounted on the same side, and
A second connecting rod 12 which is pin-coupled to the middle part of the handle 13 and the middle part of one hook 10 (on the left side in FIG. 4) connects them so that they can operate as one unit.

When the outlet 3 is closed by the side plate 6 and the bottom plate 7, the hook 1 is closed as shown by the solid line in FIG.
0 is hooked on the locking protrusion 8 to restrict the downward movement of the bottom plate 7, thereby locking the discharge port 3 in the closed state. Further, as shown by the two-dot chain line in FIG. 4, the handle 13 is rotated counterclockwise, and the hook 10 is rotated clockwise via the first and second connecting rods 11 and 12, thereby engaging The discharge port 3 can be opened by removing it from the stopper projection 8 and unlocking it. Note that the guide roller 9 is connected to this discharge port 3.
This is provided to allow the bottom plate 7 to move smoothly on the floor surface as described below when opening.

Further, in this unlocked state, the fulcrum of the second connecting rod 12 on the handle 13 side is at the dead center, the hook 10 is kept in the unlocked state, and then the locking protrusion is pressed to close the discharge port 3. When the hook 8 returns to its original position, the hook 10 and the locking protrusion 8 are prevented from colliding with each other and damaging each other.

Further, a protrusion 14 is provided on the lower front part of the main body 1 (on the right side in FIG. 4), and by engaging the L-shaped hook 15 protruding from the lower part of the temporary storage part 21, the sheet stencil can be attached. The main body 1 is held in an immovable state when the parts 29 are assembled.

Furthermore, as shown in FIG. 7, the side plate 6a of the main body 1 is
(The same applies to the side plate 6).The sheet stencil 2 is divided into small widths in the vertical direction, and each divided piece 20 is appropriately bent inward from the entrance of the push-in port 2.
This prevents the sheet stencil 29 from springing back once it has been pushed in, without interfering with the pushing in of the sheet stencil 9. Furthermore, since the amount of springback is larger on the entrance side than on the back of the main body 1, the pitch of the divided pieces 20 is made smaller toward the entrance to effectively prevent springback.

In addition, the ceiling surface 18 of the main body 1 is made of expanded metal to reduce weight, and an inverted U-shaped discharge hanger 16 is installed on the top surface slightly from the center in order to hang the main body 1 in an inclined state by a crane. It is mounted eccentrically, and a transport hanger 17 similar to that described above is mounted in the central position for transport by means of traction.

Next, a method of using the scrap container having the above configuration will be explained.

First, as shown by the two-dot chain line in FIG. 4, rotate the presser frame 4 upward to open the push-in opening 2.
As in the case of FIGS. 2 and 2, the scrap container is brought close to the temporary storage part 21, and the hook 15 is hooked onto the protrusion 14 to fix it.

Then, the push plate 28 and the cover plate 26 are operated appropriately to accumulate the used sheet stencils 29 in the main body 1 in a compressed state. Here, the pushing by the pushing plate 28 is performed up to the upper end of the pushing opening 2, as shown by the two-dot chain line A in FIG. However, for example, due to spring back, the sheet stencil 29
Even if it protrudes to the right in the figure, push inlet 2
The protruding lower end of the bottle prevents it from spilling.

Then, when the inside of the main body 1 is filled with the sheet stencil 29, the presser frame 4 is rotated downward to close the push-in opening 2. At this time, the presser frame 4 leaves a gap 5 and presses the sheet stencil 29 in a substantially horizontal direction to close the push-in port 2, so that the push-in port 2 is easier to close than a double-door type.

Further, since the push-in port 2 can be closed without being separated from the temporary storage section 21, the sheet stencil 29 will not be scattered on the floor.

After closing the push-in port 29, attach the hook 15 to the protrusion 1.
4, the sheet stencil is hooked to the transportation hanger 17 by an appropriate traction means (not shown), and transported to a predetermined discharge point, for example, near a truck bed. Then, the wire 19 of the crane is hooked onto the discharge hanger 16, and the handle 13 is operated to remove the hook 10 from the locking protrusion 8 (FIG. 8).
Thereafter, as the wire 19 is gradually wound up, the main body 1 separates from the side plates 6 and the bottom plate 7, and rises in an inclined state, leaving these at the bottom.
The opening of the discharge port 3 consisting of a surface expands (Fig. 9,
(Fig. 10) The sheet stencil 29 in the laminated state falls smoothly (Fig. 11).

When the sheet stencil 29 is completely ejected from the main body 1, the wire 19 is rewound and lowered (FIGS. 12 and 13), and the bottom plate 7 is lowered onto the floor without any manual intervention. The side plate 6 and the bottom plate 7 are bent at right angles, and the main body 1 is brought back into contact with them (Fig. 14,
Figure 15). At this time, since the hook 10 is held in the unlocked state as described above, it can return to its original position without interfering with the locking protrusion 8, and therefore the bottom plate 7 cannot return to its original position. can.

Then, after operating the handle 13 and hooking the hook 10 onto the locking protrusion 8 to lock the discharge port 3 in the closed state, the discharge port 3 is returned to the temporary storage section 21 again, and the same operation as described above is repeated.

In addition, in the state (not shown) between FIG. 10 and FIG. 11 and in the state shown in FIG. 12, the bottom plate 7 can be smoothly moved on the floor surface by the guide rollers 9.

As is clear from the above description, according to the present invention, the side plate is formed by continuously opening the side and bottom of a box shape, and is rotatably attached to the upper part of the side. A bottom plate rotatably attached to the lower part of the side plate is configured to be openable and closable, and a manual locking means for releasably locking the bottom plate to the main body is provided, as well as a bottom plate slightly eccentric from the center of the box-shaped ceiling surface. A discharge hanger is provided.

For this reason, since the ejection port is formed with two sides open, the sheet stencils are compressed and accumulated inside the main body, and even if an attempt is made to form an arch within the main body during ejection, the sheet stencils tend to collapse, and gravity overcomes the frictional force. , it is possible to prevent the occurrence of a situation in which it is impossible to fall, and it is possible to carry out a smooth discharge operation.

In addition, since the bottom plate is manually locked, it is possible to carry out the evacuation operation using a normal single-layer crane.

Furthermore, as shown in the embodiment, by making the lower part of the inlet protrude from the upper part, it is possible to prevent the sheet stencil from falling onto the floor due to spring back.
