Description

[Detailed description of the invention] [Industrial application field] The present invention is a method for converting coin rolls (wrapped coins in which a predetermined number of coins of the same denomination are wrapped in wrapping paper) that are dropped and discharged from a coin packaging unit into a roll of coins. Regarding a coin wrapping machine that corrects the horizontal position by a discharge gutter and releases the coin roll from the coin roll discharge port of the gutter, it is particularly useful to open and close the coin roll discharge port to lock the coin roll. The present invention relates to a gate device including a gate member that performs discharge.

[Conventional technology and problems]

In conventional coin wrapping machines, the coin roll dropped from the coin packaging section is corrected to a horizontal position in the coin roll discharge gutter section, and then released from the coin roll discharge port of the gutter. It is ejected from the bar release port due to the rolling of the bar due to its own weight when changing direction. In some cases, a coin roll receiving box is placed in front of this coin release outlet.
In some cases, a conveyor or chute is installed to transport the bar to another location, but in the above-mentioned discharge due to its own weight rolling, the bar is often discharged to a receiving box conveyor, etc. in an unstable posture. There are disadvantages such as the wrapping paper that is wrapped in it is easy to tear, and it is also difficult to transport by conveyor etc.

By the way, this type of coin packaging machine is provided with a gate member that closes the coin roll discharge port in the gutter section to temporarily store loose coins in the gutter section when discharging fractional coins, misrolled coins, etc.

After locking the metal bar with this gate member, I decided to release the metal bar by opening the gate member, and when I experimented, I was able to determine the posture of the metal bar when it was released, so the above-mentioned drawbacks were resolved. However, it has been found that the following drawback occurs as another problem. That is, the gate member is formed with a closing surface that closes the coin roll outlet in the gutter to prevent loose coins from spilling out of the coin roll outlet, but the closing surface of this gate member is formed on the outer peripheral surface of the coin roll. This means that when the metal bar comes into line contact with the gate member and when the metal bar is locked by the gate member and when the metal bar is released by opening the gate member, the wrapping paper wrapped around the circumferential surface of the metal bar is torn. In particular, when the direction in which the wrapping paper is wrapped around the metal bar is the same as the direction of rotation when the metal bar rolls, and the metal bar locking of the gate member is in the direction in which the wrapping paper is torn off, the wrapping paper Crushing is likely to occur.

[Purpose of invention]

The present invention was developed in view of the above points, and includes forming a plurality of bulging protrusions on the closing surface of the gate member,
By locking the metal bar with these bulging protrusions, the contact between the outer circumferential surface of the metal bar and the gate member becomes point contact, and when the gate member locks the metal bar and the gate member. To provide a gate device for a coin wrapping machine in which there is no fear of tearing off wrapping paper wrapped around a coin roll whenever the coin roll is released by opening.

[Summary of the idea]

In order to achieve the above object, the present invention corrects the coin roll dropped and discharged from the coin packaging part into a horizontal position by means of the coin roll discharge gutter part, and moves the tip of the coin roll in the horizontal position in the axial direction to the front end of the gutter part. In a coin packaging machine, a coin roll is brought into contact with a contact part, and the coin roll that is in contact with the contact part rolls under its own weight in a direction substantially perpendicular to the axis of the coin packaging machine, and releases the coin roll from the coin roll discharge port of the gutter part. It is swingably provided to open or close the coin roll discharge port of the gold roll discharge gutter section, and when the coin roll falls from the coin packaging section, the coin roll discharge port is closed and the coin roll discharge port is moved to the abutting part of the coin roll discharge gutter section. A gate member that locks the outer peripheral surface of a metal bar that contacts and rolls under its own weight, and a gate member drive unit that swings this gate member in an opening direction at a predetermined time to roll and eject the metal bar from a metal bar discharge port. The gate member has a closing surface that closes the metal bar discharge port, and a surface that is tangential to the cylindrical outer circumferential surface of the metal bar in the circumferential direction of the metal bar to be locked by the gate member. A protrusion that bulges in a chevron shape and makes point contact with the outer peripheral surface of the metal bar in the axial direction of the metal bar, and is located at each position on the closed surface corresponding to a plurality of locations in the axial direction of the metal bar. The gate member has a plurality of bulging protrusions formed respectively, and the plurality of bulging protrusions of the gate member locks the outer circumferential surface of the metal bar at a plurality of points in a state of point contact, and the gate member It is characterized in that it is in temporary point contact with the outer circumferential surface of the metal bar that rolls under its own weight even when it is opened.

The coins are stacked on the protruding coin supports 12a, 12a at symmetrical positions, and the stacking operation of the coins is continued by lowering each stacking belt 12, 12 by a certain pitch each time a coin is introduced. The coin stacking section E further includes an opening/closing shutter 14 at its lower end, so that when the packaged unit number of coins is counted by the coin counting section D and fed into the coin stacking section E, the stacking belts 12, 12 face each other. After the coin support parts 12a, 12a are lowered, they are returned to the stacking start position from the opposing outer peripheral surfaces of the stacking belts 12, 12. As a result, the number of stacked coins placed on the coin supports 12a, 12a is placed on the opening/closing shutter 14. This opening/closing shutter 14 is located in the packaging section F.
is opened at a predetermined time after the packaging cycle starts (the rotation of the camshaft 29 starts from the fixed position, which will be described later).
The stacked coins of the packaging unit number are sent to the packaging section F, where the coins are packaged.

The packaging section F has a plurality of packaging rollers 15, 16, and 17, at least one of which is a movable roller, and a paper guide (not shown) is provided between these rollers so that the packaging rollers and The paper guide forms a substantially sealed packaging space. 18 holds the stacked coins at the wrapping position until the guide of the coins from the coin stacking section E and the tightening of the upper and lower ends of the wrapping paper wrapped around the periphery of the stacked coins by the winding hooks 19, 19 are completed. It is the supporting rod that supports it. 2
0 is the camshaft, and one rotation of the camshaft determines one packaging cycle, and it moves the packaging roller, the winding hook,
A group of cams that control the movement of the support rod are fixed.

The paper feed section G receives wrapping paper W from the wrapping paper roll 21.
The paper feed rollers 22, 22 that stretch and feed the coins, the arcuate guide plate 23, and the wrapping paper that is fed along the arcuate guide plate 23 and between the wrapping rollers 15, 16, 17 is wrapped around the periphery of the stacked coins. A chevron-shaped cutter 24 is provided which is tensioned when the paper is wrapped, and contacts the wrapping paper to cut it into a predetermined length when the wrapping paper is tensioned.

The bar chute section H includes packaging rollers 15, 16,
It is equipped with a bar gutter 25 which faces below the bar 17 and horizontalizes the falling gold bars, and faces the part of the gutter 25 in the area where the gold bars fall, and only during the release period of the bars, the bar is placed in the position indicated by the dashed line in Figure 2. A switching guide 26 is rotatably provided to allow release of the liquid. This switching guide 26 is
Normally, it is located in the solid line position, and serves to prevent coins that are misaligned during packaging, coins that are not wound, etc., from being discharged to the end side of the gutter 25.

A gate member 27 is installed at the coin roll outlet 25a of the gutter 25.
is provided.

This gate member 27 has a closing surface 27b that can close the coin roll outlet 25a of the coin roll gutter 25 to prevent loose coins from falling and retain the loose coins in the gutter 25. On the surface on the 25 side, two protruding protrusions 27a, 27a for locking the metal bar are formed on the left and right in a direction perpendicular to the axis of the metal bar.

The metal bar outlet 25a is formed by the closing surface 27b.
The closed state is maintained by operating a rounding button (a button for discharging fractional coins from the coin stacking section E through the coin wrapping section F to the gutter 25 without wrapping them). Further, even when coin stacking is detected in the coin stacking section E, the closed state is maintained in the same manner. After the closure, when coins are to be collected, the gate member 27 is opened by operating a button, and the coins are collected in the coin receiving box K.

For details, FIG. 6a shows the shape seen from the front in FIG. 2, and FIG. 6b shows the shape seen from the top in FIG. 2. And the bulging protrusions 27a, 2
7a is a gate member 27 formed by pressing, for example.
A part of the surface is processed to protrude, and its shape is an arcuate chevron shape when viewed from the top, as shown in FIG. 6b. A metal bar falling vertically in the gutter 25 (indicated by the dashed dot line in Figure 6b) is converted from vertical to horizontal direction while moving in the direction of the two-dot chain arrow. (shown by the two-dot chain line in b). The tip of the metal bar in the axial direction comes into contact with the abutting part 25b at the front end of the gutter 25, and is guided by the abutting part 25b and moves along the bottom surface 25c of the gutter 25 in the direction of the dashed double-dashed line arrow. The bulging protrusions 27a, 27a make point contact with the circumferential surface of the bar (since the circumferential surface of the bar is a circle, the top line of the bulging protrusions 27a, 27a becomes a tangent, and the contact area is a point contact). to lock the bar (the bar position indicated by the solid line in FIG. 6b). At the time of changing the attitude of the metal bar to the horizontal attitude, the vertical metal bar (indicated by the dashed dot line in Fig. 6b) heads towards the surface of the gate member 27 in a horizontal attitude via the path indicated by the solid arrow, and as shown in Fig. 6b. Although it may be in the state shown by the solid line, even in that case, it will not come into point contact with the bulging protrusions 27a, 27a and tear the wrapping paper on the circumferential surface of the metal bar, as described above.

The bulging protrusion 2 of the gate member 27 that comes into contact with the metal bar
Since 7a and 27a are in point contact as described above, the wrapping end Wa of the wrapping paper W on the circumferential surface of the metal bar will not be peeled off, and the wrapping paper will not be torn.

In addition, after the two points are supported and positioned by the bulging protrusions 27a, 27a, as the gate member 27 is opened, the point contact portion with the metal bar changes to the bulging protrusions 27a, 27a on the lower side. Even if the bar is released, the bar is always released through two-point contact, so the bar is supported at two points until the bar releases point contact with the bulging protrusions 27a, 27a, and the rolling of the bar is prevented. The moving direction posture is maintained, and there are no problems such as the rolling direction being diagonal.

Furthermore, since the contact between the gate member 27 and the metal bar is point contact when the metal bar rolls while in contact with the gate member 27, the winding end Wa of the wrapping paper W will not be torn off. .

As described above, the bulging protrusions 27a, 27a serve to prevent the wrapping paper from tearing when the coin roll is locked and when the coin roll is released, and to serve as a rolling guide in the normal direction when the coin roll rolls. preside over. As a supplementary note regarding the illustrated state of the coin roll in Figure 6a, the dash-dot line, chain-double-dot line, and solid line illustrations in Figure 6b correspond to the coin rolls illustrated in the dash-dotted line, chain-double-dot line, and solid line in Figure 6a. .

The gate member 27 configured in this manner is allowed to swing around a shaft 28 supported by a machine frame (not shown). A fixing piece 29 is fixed to the right side of the gate member ₂₇ in FIG. 29
is connected to. A detection recess 31a is formed on the outer periphery of the cam plate 31 to position the gate member 27 in a fully closed position (normal position), and a gate member position detection switch is turned on and off by the outer periphery of the cam plate 31. SW ₁ is installed on the machine frame side.

A shoot plate 35 is provided between the coin roll discharge port 25a and the coin roll lift I, and a number of long holes 35b are formed in the bottom surface 35a of the shoot plate 35 toward the coin roll lift direction. When the switching guide 26 is in the state shown by the dashed line, loose coins such as miswound coins and odd number coins are discharged through the long holes 35b.
The coins are received in the loose coin receiving box K installed at the bottom of the coin counter 5, and only the properly wrapped coins are lifted onto the coin bar lift I.
The shot board 3 is also

c is formed, and its end is fixed to the trough 25. A metal bar receiving detector P1 (micro switch type) for detecting when a metal bar has been received in the carrier section is disposed on the lower right end of the bottom surface _35a of the shoot plate 35 in the drawing.

The metal bar lift I includes a shaft 37 supported by a lift frame 36, and a lower pulley 3 fixed to the shaft 37.
8, 38, a shaft 39 supported by the frame 36, an upper pulley 40, 40' fixed to the shaft 39;
It has belts 41, 41' wound around each pulley 38, 40 and 38', 40'. A carrier section 42 is fixed to these belts 41, 41'.

This carrier part 42 is connected to a contact plate 43 which is in contact with the back side of the belt (right side in the figure) of the right belt part of the belts 41, 41' (see FIGS. 2 and 3).
and a contact plate 44 with which the belt surface (left side in the figure) contacts and which clamps the belts 41, 41' between the belt surface 43 and the contact plate 43. It is located between the belts 41, 41' and has a width that contacts the opposing inner surfaces of the belts 41, 41' in order to determine the widthwise position of the belts 41, 41', and has a thickness that is slightly smaller than the belt thickness. A liner plate 45 is sandwiched and fixed between the contact plates 43 and 44.

The contact plate 44 has bearing parts 44a, 44a formed at its lower end, and the liner plate 45 also has bearing parts 45a, 45a formed at its lower end.

The metal bar receiving plate 46 has bearing portions 46a, 46 at its right end.

Therefore, the carrier part 42 that receives and holds the metal bar is the metal bar receiving plate 46 and the contact plate 44, and the bent parts 46a, 46a are used to prevent the axial end surface of the metal bar from moving in the axial direction. It is also useful as a regulatory action in cases.

Bearings 49, 49 are fixed to the lower surface of this metal rod receiving plate 46, and a follower 50,

It is rotated by M ₃ (Figure 4).

FIG. 4 shows a control block diagram, and in particular, the operation command section indicated by 53 includes a start button, a wrapping paper cut detection switch (not shown), and the like. Reference numeral 58 denotes a rotation drive unit, which includes a motor for rotating the paper feed roller 22 and a motor for rotating the packaging rollers 15, 16, and 17. The time detector 54 measures the time after the camshaft 20 starts rotating from the fixed position, and at a predetermined time (when measuring 400 ms) rotates the motor M ₁ through the first control section 55 to fully open the gate member 27. position to the half-open position. Note that after the start command, the operation command section 53 inputs a normal signal to the first control section 55 unless an abnormality such as poor paper cutting occurs. Since this operation command section 53 is not directly related to the gist of the present invention, it will be assumed that a normal signal is output.

FIG. 5 is a timing table, which will be described later along with an explanation of the operation.

Next, the operation of the coin wrapping machine as a whole will be explained.

The coins stored in the storage hopper part A in FIG. The coins are delivered in a single layer in the thickness direction, and the coins are regulated and aligned in a line at the entrance of the coin passage C, and are forcibly transferred within the passage C by a transfer belt 9. While the coins are being conveyed, small-diameter coins mixed with the coins are removed into the sorting slot, and only coins of regular denominations are sent to the coin stacking section E after passing through the sensor 10 of the coin counting section D.
When feeding the coins, the stacking belts 12, 12 are driven by a predetermined pitch, and the coin supporting parts 12a, 12
Coins are stacked one after another on a. When the coin counter D counts the number of coins in a packaging unit, the stopper 11 moves forward to stop the next coin of that number, and also temporarily stops the rotary disk 3 and the conveyor belt 9. The counting signal of the number of packaging units from the sensor 10 is transmitted by continuously rotating the stacking belts 12, 12, lowering the opposing inner surfaces of the belts, raising the outer surfaces, and moving the coin supporting parts 12a, 12a upward again. Position it at the upper initial position on the front side. Coin support part 1
The stacked coins placed on 2a and 12a are then placed on the opening/closing shutter 14 and held there. Next, in FIG. 4, when a signal indicating that the coin counting unit D has finished counting the number of coins per package and a signal from the switch SW ₄ indicating that the camshaft 20 is in the normal position are input to the first control unit 55. Motor for camshaft 20
Rotate _M3 to rotate the camshaft 20 once. One rotation of the camshaft 20 completes one packaging cycle. After the camshaft 20 starts one rotation, the stacked coin support rod 18 is first moved radially from the lower side of the packaging space to be directly below the packaging space, and then ascends within the packaging space to open and close the opening/closing shutter. 14
to the bottom of. Immediately thereafter, a cam (not shown) of the camshaft 20 causes a cam switch (not shown) to switch to a rotation timing of a predetermined angle of the camshaft 20, actuating a shutter solenoid (not shown) and opening/closing the shutter 14. Let it open. By opening, the stacked coins are transferred onto the stacked coin support rod 20, and as the support rod 20 is lowered, the stacked coins are also lowered. When the upper end of the stacked coins moves below the opening/closing shutter 14, the cam switch is turned over and returned to its original position, deactivating the shutter solenoid and closing the opening/closing shutter 14. The coin counting section D is operated by a signal from a counting start switch (not shown) in the operation command section 53 operated by a cam (not shown) on the camshaft 20, and the stopper 11 is moved out of the course. At the same time, the rotating disk 3 and the transfer belt 9 are driven to restart counting and piling operations.

The stacked coin support rod 18 continues to descend within the packaging space, descends to the packaging position, and is temporarily stopped. Immediately after that, the wrapping rollers 15, 16, and 17 that rotate pick up the stacked coins and rotate them. Immediately after that, the tip of the wrapping paper W is fed between the circumferential surface of the stacked coins and the wrapping roller 15 by the paper feed rollers 22, 22, and is wound around the circumferential surface of the stacked coins, and the subsequent part of the wrapping paper W is tensed, pressed against the cutting blade 24, and cut. The tip of the wrapping paper, which has a newly formed protruding V shape by cutting, is transferred to the wrapping roller 1 by the paper feed rollers 22, 22 at a predetermined time of the wrapping cycle.
It is located at the start position near No. 5 in preparation for the paper feeding operation of the next packaging cycle.

The pieces of wrapping paper that have been cut and are being wrapped around the circumferential surface of the stacked coins are moved as the winding hooks 19, 19 advance in the radial direction from between the wrapping rollers 15, 16, and then move toward each other. tightened by
When the crimping operation is completed, the winding hooks 19, 19 move away from each other, and then move away in the radial direction and move away from between the packaging rollers 15, 16. Immediately after that, the support rod 18 moves downward from the bottom surface of the stacked coins, then moves in the radial direction, returns to a position where it does not interfere with the falling of the coin bars, and waits. Immediately after that, the camshaft 20 returns to its normal position, and the first control section 55 is activated by a signal from the switch SW4 shown in FIG. ₄ to stop the motor _M3 for the camshaft 20. However, when the camshaft 20 returns to its normal position, that is, when the signal from the switch SW ₄ is input to the first control section 55, the coin counter D has finished counting the next packaging unit. , the camshaft 20 continues one revolution without stopping (and without stopping the motor _M3 ), and the next cycle of packaging continues.

Gate member 2 for such a packaging cycle
7 and the operation of the metal bar lift I will be explained with reference to FIGS. 4 and 5.

To explain the normal operation a of the motors M ₁ , M ₂ , and M ₃ in FIG. 5, the motor M 1 for the gate member 27 starts at the time T _{1 (ta time) after the camshaft 20 starts one rotation, and after the lapse of time T 1} , the motor M ₁ for the gate member 27 Start rotating. When time t _b has elapsed after the rotation of the motor M ₁ , the motor M ₁ is stopped by a signal from the elapsed time detector 54 shown in FIG. 4 .
At this time, the gate member 27 stops at the half-open position indicated by the dashed line in FIG. 3, leaving the metal bar in a locked state. On the other hand, the carrier part 42 is in its home position at the top in FIG. 3, and the motor _M2 for raising and lowering the carrier part 42 lowers the carrier part 42 by rotating in the normal direction, and raises it by rotating in the reverse direction. be. and the fifth
In the figure, motor M ₂ is the time detector 54 in Figure 4.
When the signal is input to the first control section 55 when detecting the elapsed time ta after the start of rotation of the camshaft 20, a corresponding signal is input from the first control section 55 to the second control section 56, and the signal and , detector P ₂ indicates that there is no bar (in the case of a packaging cycle immediately after the packaging starts, check whether a bar is blocking detector P ₂ ) or that the bar has passed (in the case of the second and subsequent packaging cycles). In this case, when a signal indicating whether the coin roll passes through the detector P ₂ after the roll blocks the detector P ₂ is detected, both signals are input to the second control unit 56. , rotate the lift motor _M2 forward for td time. td
After time has elapsed, switch SW ₂ detects the lowering of carrier section 42 to the coin roll receiving position, and motor M ₂
to stop. On the other hand, the detection by the switch SW ₂ causes the gate member motor M ₁ to rotate for a time tc, and then the switch SW ₁ detects the fully closed position of the gate member 27 and stops the motor M ₁ . When the motor _M1 rotates during this time tc, the gate member 27 moves from the half-open position to the fully open position and then to the fully closed position (the cam plate 31 in FIG. 3 rotates in the direction of the arrow), and from the half open position to the fully open position. When moving the metal bar and the gate member 27
It is released from the lock, rolls on the bottom surface 35a, and is ejected into the carrier section 42. Motor for gate parts
M ₁ is stopped by switch SW ₁ when the tc time has elapsed, but the camshaft 20 is rotated 360° after one rotation and continues the next rotation to continue the next packaging cycle.
When ta time elapses from T ₄ time, rotate again for tb time,
The gate member 27 is stopped at the half-open position.

On the other hand, when the detector P ₁ detects the receipt of the coin roll into the carrier section 42, the motor M ₂ starts to reverse the rotation time td, and when the carrier section 42 reaches the coin roll release position, the switch SW ₃ is turned off. Instead, the second control unit 56 stops the motor _M2 . Also this motor _M2
The next forward rotation of is a signal corresponding to the signal of ta time elapsed from the time of T ₄ (signal from 54 → 55 → 56),
Detector P ₂ coin passing signal (number of coins after 2nd roll)
is started when input to the second control unit 56 (FIG. 4).

In the case of recovery delay b, that is, when dealing with the movement delay of the carrier section 42 without temporarily stopping the camshaft 20, the rotation of the camshaft 20 by motor M ₃ is the same as in normal a, and the rotation of motor M ₁ is The process remains the same until the gate member 27 is moved to the half-open position. However, the normal rotation of motor M ₂ (lowering of the carrier section 42) is detected by detector P ₂ , which indicates that there is no rotation (first one).
Or, the detection time of the passage of coins (second and subsequent ones) is T ₁
Since it is later than the time, the detection time of switch SW ₂ is also delayed, and the start time of rotation of motor M ₁ during the tc time for ejecting the metal bar is also delayed.

Abnormal delay c (when the camshaft 20 is temporarily stopped at a position of 115°, the camshaft 20 that is temporarily stopped
The angular position of the stacked coin wrapping rollers 15, 16,
17 is immediately after being clamped, and the leading edge of the wrapping paper has not yet been fed between the wrapping roller 15 and the circumferential surface of the stacked coins).

The camshaft 20 rotates up to 115° in FIG. 5, and the _switch SW ₅ in FIG. Detector P ₂ → Second control unit 56 → First control unit 5
Since the signal to the camshaft 5 is not input to the first control unit 55, the camshaft 2 rotated by the motor _M3
Rotation is temporarily interrupted when the rotation angle reaches 0 to 115°.
This rotation of the camshaft 20 (resuming rotation from an angle of 115°) can be restarted within the time period te from time T ₂ , and the detector P ₂ detects no bar (first bar). ) or the time T ₃ after tf time has elapsed since the passing of the coin roll (the second and subsequent coin rolls) is (T ₂ + te)
If the time has elapsed, the rotation of the camshaft 20 is restarted. Note that if the time T ₃ is later than the time (T ₂ +tf), the entire packaging machine is stopped. Motor _M1 , _M2
The command to drive or stop is carried out by the elapsed time detector 54, detectors P ₁ and P ₂ , switches SW ₂ and SW _3, etc. in the same way as in the case of normal a and delayed recovery b.

Note that the control section 57 of the present invention is composed of a first control section 55 and a second control section 56, but it is composed of one microcomputer, and both 55, 5
6 may be combined. Also, in the illustrated embodiment, the detector for the arrival of a predetermined period in the configuration is a switch.
Although SW ₅ may be performed using a time elapsed detector 54. In other words, it is possible to measure the time up to the angle of 115° with the time elapsed detector 54 and emit a signal at that point.

Furthermore, the command to start driving the motor _M1 for the gate member 27 at time _T1 in FIG. .

[Effect of idea]

As explained above, according to the present invention, a plurality of protruding protrusions are formed on the closing surface of the gate member, and the metal bar is retained by these protruding protrusions, so that the bar The contact between the outer circumferential surface of the metal and the gate member is point contact, and the metal bar is wrapped around the metal bar both when the outer peripheral surface of the metal bar is locked by the gate member and when the metal bar rolls and is released by opening the gate member. This has the excellent effect of eliminating the risk of tearing off the wrapping paper.

In the illustrated embodiment, the gate member 27 is temporarily stopped at a half-open position in order to release the bar from a position as close to the bar lift I as possible, and this is particularly effective. Of course, the same effect can be obtained even if the opening is not necessarily in the half-open position but in the fully closed-fully open position.
