A mechanism related to opening and closing, especially a mechanism that allows only one selected lid to be opened from a plurality of lids, prevents other lids that are not selected from being opened, and allows easy confirmation of the selected lid. Regarding.

[Prior art and its problems]

FIG. 5 is a publicly known configuration diagram of the above-mentioned change dispensing mechanism, in which 1, 2, and 3 are coin reservoirs for storing 10 yen, 50 yen, and 100 yen coins inputted in advance; 4, 5, and 6 are the lids of these coin reservoirs. Numerals 7, 8, and 9 are configured to take in the number of coins specified by the signal from a control device (not shown) from the coin reservoirs 1, 2, and 3, respectively. This is a coin counting machine that ejects from 8a and 9a, and 10 is the ejection port 7.
This is a conveyor belt configured to convey coins released from each of the coins a, 8a, and 9a to the outlet 11. The change dispensing mechanism is constructed as described above, and in this case, the lids 4, 5, and 6 can be opened individually. Therefore, in the conventional change dispensing mechanism, the coin reservoirs 1, 2, and 3 are arranged close to each other, so if you try to insert coins into the target coin reservoir with multiple lids open, There are problems in that a different denomination is inserted into a coin reservoir other than the coin reservoir into which coins are to be inserted, and coins of a different denomination may be thrown out of the coin reservoir. In addition, in Fig. 5, the lids 4, 5,
6 are independent from each other, so it is necessary to lock each of these lids.For this reason, in such a change dispenser, it is necessary to unlock and lock the lids 4, 5, and 6. Another problem is that replenishment work is troublesome.

[Purpose of invention]

The present invention solves the above-mentioned problems with the conventional change dispensing mechanism, and makes it possible to open only a selected one of the lids of a plurality of juxtaposed containers, while other lids that are not selected can be opened. It is an object of the present invention to provide a mechanism for preventing simultaneous opening of a plurality of lids, which prevents the opening of a plurality of lids from occurring at the same time and allows easy confirmation of a selected lid.

[Key points of the idea]

In order to achieve the above object, the present invention includes a plurality of lids each rotatably supported around a rotating shaft sequentially arranged on one axis, and each lid is provided with at least one protrusion; a lid rotation mechanism provided for each lid that opens the lid at a predetermined angle when a driving force is applied; a linear edge portion formed parallel to the axis; A stopper that prevents the lid from opening by coming into contact with the lid; and a stopper guide mechanism that allows the stopper to move in the axial direction; constitutes a mechanism for preventing the simultaneous opening of a plurality of lids; The stopper is provided with at least one cam that selectively applies the driving force to only one of the lid rotation mechanisms as the stopper moves in the axial direction, and a cam is provided on the edge of the stopper to apply the driving force selectively to only one of the lid rotation mechanisms as the stopper moves in the axial direction. A notch through which the protrusion can pass is provided for each cam at a position corresponding to the position of the cam. With this configuration, the stopper guide mechanism allows the stopper to be moved in the axial direction. When the lid is moved, one lid rotation mechanism is selectively driven by a cam to open the lid corresponding to the rotation mechanism at a predetermined angle, thereby making it easy to confirm the selected lid. At this time, the protruding body of the selected lid is allowed to pass through the notch of the stopper, so that only one of the plurality of lids can be selectively opened, and the other unselected lids can be opened selectively. A mechanism for preventing the simultaneous opening of a plurality of lids is provided, which prevents the lids from being opened and allows easy confirmation of a selected lid.

[Example of idea]

Figure 1 is a drawing that best expresses the features of the book. This figure is an enlarged view of the main part of the mechanism shown in Figure 4, viewed from the arrow R. Figure 2 is a cross-sectional view taken along the Y-Y line in Figure 1. The figure is a perspective view of the main parts in Figures 1 and 2, Figure 4 is a configuration diagram of an embodiment of the present invention, Figure 4A is a front view, and Figure 4B is a view taken from arrow P in Figure 4A. It is a diagram.

First, FIG. 4 will be explained. In FIG. 4, 12 connects the three coin counters 7 to 9 through struts 13, 14, 15, each one end of which is fixed on each side of the coin counters 7, 8, 9. The frame 12 is a rectangular plate-shaped frame to which the other ends of the pillars 13, 14, and 15 are fixed, and the frame 12 is arranged substantially vertically. Numerals 16, 17, and 18 are lids with a key-shaped cross section that cover the upper openings of the coin reservoirs 1, 2, and 3, and these lids have the key-shaped bent portions 16.
a, 17a, 18a are opposed to the upper end surface of the frame 12, and the bent portions 16a, 17a, 1
8a and the frame 12.
It is rotatably attached to the frame 12 by a, 19b, 20a, 20b, 21a, and 21b. In this case, the respective axes of the hinges 19a to 21b are arranged so as to substantially lie on an imaginary linear axis XX in space. 22, 23, 24
are rectangular parallelepiped projecting ends provided on the outer surfaces of the bent portions 16a, 17a, and 18a of the lid so as to project from the respective outer surfaces, and 25 and 26 are pins each having one end fixed to the frame 12. 27 has upper edge 27a with upper rectangular notches 28a, 28b,
This stopper 27 is a rectangular plate-shaped stopper provided with a stopper 28c, and pins 25 and 26 are inserted into groove-like through holes 29a and 30 provided in the stopper, respectively, and the stopper 27 is supported by the frame 12 by these pins. There is. 25a and 26a are pins 25 and 26, respectively.
This is a pin installed on the head of the machine to prevent it from falling out. The main part of the stopper 27 is formed so as to be supported in a posture parallel to the frame 12, and the stopper 27 is
In Figure A, pins 25, 26 and through holes 29, 30 are formed so that when the stopper is pushed or pulled in the left-right direction, it moves approximately parallel to the axis XX, and furthermore, the stopper 27 has an upper edge 27a. It is arranged so as to be parallel to the axis XX. 31 is the pin 25, 26 and the retainer 25a, 2
6a and through holes 29 and 30, the stopper 2
This is a stopper guide mechanism that allows movement of the stopper 7 in the direction of the axis XX.

In FIG. 4, each part is configured as described above, so for example, the lid 16 is attached to the hinges 19a, 19
Q shown in Figure 4B by rotating around the axis of b.
When opening in the direction of the arrow, when the lid 16 is closed, the surface of the protrusion 22 and the notch 28a
~ Upper edge 27 of the stopper where 28c is not provided
Since the main part is configured so that it faces the part a across the narrow diameter 32, the stopper 27 is moved in the direction of the axis XX and the narrow
32 is formed, when the lid 16 rotates, the side surface of the protrusion 22 comes into contact with the upper edge 27a.
Therefore, in this case, the lid 16 cannot be opened. However, when the stopper 27 is moved in the axis XX direction so that the side surface of the protrusion 22 faces the notch 28a, the protrusion 22, which rotates as the lid 16 is opened, does not touch any part of the stopper 27. The waist portion is configured to cross the notch 28a without contacting the cutout 28a. Therefore, in this case, lid 1
6 can be opened. Also, in Figure 4,
Like the lid 16, the lids 17 and 18 have protrusions 23,
When the protrusions 23 and 24 are not facing the notches 28b and 28c, respectively, the opening is prevented by the upper edge 27a of the stopper, and when the protrusions 23 and 24 are facing the notches 28b and 28c, respectively, the lid 17 , 18 are constructed so that the opening of the lid 16 is not prevented.
The spacing between adjacent notches is set relative to the spacing between adjacent protrusions so that only one of the protrusions can be opened. Therefore, according to the mechanism shown in FIG.
By moving in the X direction, only one lid selected can be opened.

In the mechanism shown in FIG. 4, for example, the lid 16
When opened, after the protrusion 22 crosses the notch 28a, the side surface of the protrusion 22 that was initially facing the notch 28a comes into contact with the frame 12, preventing further rotation of the protrusion 22. With the frame 12 blocking the protruding body 22 and the rotation of the protruding body 22 being thus prevented, the protruding body 22 is still in the notch 28a.
The main parts are arranged so that they are located inside. Therefore, when the lid 16 is open, the stopper 27 cannot be moved in the direction of the axis X-X, and as a result, when the lid 16 is in the open state, it is impossible to open the lids 17, 18. Similarly, in FIG.
When one of the 8 lids is opened, it is impossible to open the remaining two lids.

In FIG. 4, cutouts 28a, 28b, 28c
If the stopper 27 is positioned such that none of the lids 16 to 18 correspond to the corresponding protrusions 22, 23, 24, all of the lids 16 to 18 cannot be opened. Therefore, if the stopper 27 is provided with a locking mechanism for fixing the stopper at such a position, the same effect as that provided by locking mechanisms provided individually on the lids 16 to 18 can be achieved. That is, when the mechanism as shown in FIG. 4 is used in the change dispenser described above, the operations of unlocking and locking the lids 16 to 18 are simple, so that the work of replenishing coins, etc. becomes easy.

Next, FIGS. 1 to 3 will be explained. In these figures, 33 is an L-shaped metal fitting with a through hole 34 provided at the corner, and a monopod 33a of this metal 33
A leaf spring 35 is attached to the upper surface 33b of the leg 33a at the end of the leg 33a.
In the L-shaped fitting 33 provided with a leaf spring 35, which is fixed in a cantilever shape, one leg 33a opposes the lower surface of the lid 18 with a gap 36 in between, and the other leg 33c of the L-shaped fitting 33 The frame 12 is disposed opposite to the side surface of the coin reservoir 3 with a gap 37 interposed therebetween;
It is rotatably supported by a mounting bracket 38 fixed to the frame 12 via a shaft 39 fitted into the through hole 34 and fixed thereto. 40 is fixed at one end to the stopper 27 so as to protrude in the direction of the frame 12 from the stopper 27, and the other end is fixed to the frame 12.
The cam 40 is a cantilever-shaped cam configured to pass through a slit 41 provided in the cam 40, and the cam 40 has a plate shape with a free end formed in the shape of an isosceles trapezoid. Further, the stopper 41 is formed to be elongated so that when the stopper 27 is moved via the stopper guide mechanism 31, the cam 40 also moves without any trouble.

In FIGS. 1 to 3, each part is configured as described above, so if the stopper 27 is now moved and the cam 40 is approached from the L-shaped fitting 33 side to the coin reservoir 3, the cam 40 As the free end of the cam 40 enters the gap 37 between the L-shaped fitting 33 and the frame 12, the free end of the cam 40 pushes out the other leg 33c of the L-shaped fitting 33, and as a result, the fitting 33
9 in the clockwise direction, the free end of the leaf spring 35 pushes up the lid 18. Therefore, the lid 18 is slightly opened. However, at this point, the notch 28c of the stopper 27 is still in the lid 1.
Since the cover 18 is not configured to sufficiently oppose the protrusion 24 at 8, the protrusion 24 comes into contact with the upper edge 27a of the stopper, preventing the lid 18 from opening.
Therefore, in this case, as the cam 40 moves, the metal fitting 33
is rotated, but since the leaf spring 35 is curved, the protrusions 24 and the upper edge 27a that abut each other are not damaged. When the stopper 27 moves further, the notch 28c and the protrusion 24 are finally in a state where they are opposed to each other. Therefore, the lid 18 can be opened,
The deflection of the leaf spring 35 is restored. The metal fitting 33 and the leaf spring 3 are connected so that the lid 18 is opened at a predetermined angle when the leaf spring 35 has recovered its deflection.
5. Main parts such as the lid 18 and a cam 40 are configured, that is, these main parts constitute a lid rotation mechanism 42 that opens the lid 18 by a predetermined angle when driving force is applied by the cam 40. .

In the above example, the cam 40 is inserted into the coin reservoir 3 from the side of the metal fitting 33.
The explanation was about the operation of each part when the stopper 27 is moved so as to approach it, but in Figs. In order to operate as shown in FIG. That is, in this case, when the stopper 27 is moved, the lid 18 first opens a little, and then the rear lid 18 becomes openable, so that the lid 18 is already opened at a predetermined angle.
The cam 40 and the notch 28c are provided at corresponding positions.

Now, the above has been an explanation of each mechanism related to the lid 18, but as shown in FIG.
Lid rotation mechanisms 43 and 44 having the same function as cam 40 are provided on the stopper 27, and although not shown, cams having the same function as the cam 40 correspond to the notches 28b and 28a, respectively. It is provided. Therefore, in FIG. 4, for example, if you want to open the lid 17, move the stopper 27 to bring the cam corresponding to the notch 28b closer to the lid rotation mechanism 43, the lid 17 will open a little, and eventually the notch 28b will open. The lid 17 can be opened when the protrusion 23 faces the lid 17, and the lid 17 is opened at a predetermined angle. If the lid rotation mechanism 43 and the cam that drives it are not provided, the lid 17 will not open even if the lid 17 is in the openable state.
Although it is difficult to identify visually from among the lids 16 to 18, as mentioned above, in FIG. 4, the lid 17 that can be opened is in a half-open state, so it is easy to confirm. . That is, the mechanism shown in FIG. 4 allows only one selected lid of a plurality of juxtaposed containers to be opened, and prevents other unselected lids from being opened.
This is a mechanism that prevents multiple lids from being opened simultaneously, allowing easy confirmation of a selected lid.

In the above-described embodiment, the stopper 27 is provided with three notches 28a, 28b, and 28c, but in the present invention, the number of such notches may be more than three, or may be one. be. Further, in the present invention, when a plurality of notches are provided in the stopper 27, the notches are provided in correspondence with the intervals between the protrusions so that only one of the protrusions provided on the lid can selectively pass through the notch. It is sufficient if the interval is set. In the present invention, the cam provided on the stopper is arranged at a position corresponding to each notch provided in the stopper. Furthermore, the present invention is not limited to the mechanism for the three lids 16, 17, 18 as described above, and the above-described leaf spring 35 may not be provided, and the present invention It is obvious that it is possible to automatically open the lid by increasing the elasticity of the leaf spring 35.

[Effect of idea]

As described above, the present invention includes a plurality of lids, each of which is rotatably supported around a rotation shaft sequentially arranged on one axis, and each of which is provided with at least one protrusion; A lid rotation mechanism provided for each lid that opens the lid by a predetermined angle when a driving force is applied; a linear edge formed parallel to the axis; the protruding body rotates around the edge when the lid opens a stopper that prevents the opening of the lid by being attached to the part; a stopper guide mechanism that allows the stopper to move in the axial direction; and a stopper guide mechanism that prevents the simultaneous opening of a plurality of lids; Further, the stopper is provided with at least one cam that selectively applies the driving force to only one of the lid rotation mechanisms as the stopper moves in the axial direction, and the lid is provided with an opening operation at the edge of the stopper. Since a notch through which the protrusion can pass is provided for each cam at a position corresponding to the position of the cam, with this configuration, the stopper guide mechanism allows the stopper to be moved in the axial direction. When the lid is moved, one lid rotation mechanism is selectively driven by a cam to open the lid corresponding to the rotation mechanism at a predetermined angle, thereby easily confirming the selected lid. At this time, the protruding body of the selected lid can pass through the notch of the stopper, so that only one of the plurality of lids can be selectively opened. This has the effect of providing a mechanism for preventing the simultaneous opening of a plurality of lids, which prevents unselected lids from being opened and also allows easy confirmation of the selected lid.
