The present invention relates to a cup feeding device provided in a cup vending machine. An apparatus for discharging the cups stacked in the vertical direction sequentially from the lowest one and discharging them. A plurality of cups freely rotated around the cup discharge hole as previously disclosed in Japanese Unexamined Patent Publication No. 2-35693 A cup dispensing apparatus is known in which a pinion gear is reciprocated by a rack gear reciprocating by a solenoid device to separate and maintain a cup by a blade formed on the pinion gear. .

When the remaining number of cups received by the cup dispensing apparatus is reduced, a predetermined number of cups fall from the cup column to the cup dispensing apparatus in the arrangement of the cups to be supplied.

By the way, the replenishment cup which falls at the time of replenishment does not overlap with the remaining cup in a cup delivery apparatus, but hangs over the edge of a residual cup, and it may become clogged and may interrupt the delivery of a cup.

In this case, a countermeasure can be considered in such a way that the replenishing cup, which is stopped over the edge of the cup, collides with the appropriate exclusion member from the rear side and falls to the normal position.

However, depending on which part of the cup's edge is spread, the cup's position or the inclined direction of the cup varies in various ways. It was impossible to make sure that the cup was clogged because the case of knocking and dropping it was dropped.

In addition to the usual cup dispensing mechanisms, there is a need for a mechanism for tapping the cups, resulting in a complicated configuration and an increase in cost.

An object of the present invention is to provide a cup feeding apparatus capable of replenishing a cup to be replenished in a normal state, and to eliminate clogging of the cup.

The present invention provides a cup storing portion for stacking and storing a plurality of cups in an up and down direction, a cup dispensing device provided in the lower portion of the cup storing portion, and having a plurality of cup separating cams arranged in a circumferential shape in the circumferential shape; In the cup supply apparatus provided with the drive apparatus which reciprocally rotates one cup separation cam, and delivers the lowest cup of said cup storage part,

Normally, the above drive is controlled to reciprocate the cam at a predetermined angle for separating the cup, while the cap is reciprocated at an angle narrower than the predetermined angle so as not to separate the cup at the time of refilling the cup. And a control device for controlling the drive device to reciprocally rotate the remaining cup in the cup delivery device.

The cup separating cam is controlled to be reciprocally rotated at a predetermined angle by a control device when a cup discharge command is issued, and performs a cup dispensing operation for separating the lowest cup from the stacked cups.

In addition, when the cup in the cup dispensing apparatus becomes small and the cup is refilled, the cup separating cam is reciprocated by the control device within a rotation range in which the cup is not separated, thereby producing a reciprocating rotation of the remaining cup.

Therefore, when the refill cup is clogged by the remaining cup, the bottom of the refill cup is shaken by the remaining cup, and the refill cup can be automatically dropped to a regular position where the cup is heated.

EXAMPLE

Next, the Example of this invention is described based on drawing.

1 receives a row of cups introduced from a cup column (not shown) disposed above and introduces a plurality of cups, which are rows of cups, into a cup separating cam 3 of a cup dispensing apparatus 2 disposed below. It is a guide box which becomes a cup storing part.

The guide cylinder 1 is mounted on the substrate 4, and an upper portion of the guide cylinder 1 is provided with a guide portion 1a diffused upward to reliably receive the heat of the cup introduced from the cup column. It is.

In addition, between the guide cylinder 1 and the cup dispensing apparatus 2, a separate guide tube 5 having a short length is provided so that the cup can be smoothly and reliably taken into the cup dispensing apparatus 2. .

7 is a drive device driven according to a cup delivery command from a control device of a microcomputer configuration to operate the cup delivery device 2, which is a gear motor 8 and this gear motor 8; Of the cam 9 attached to the rotary shaft 8a of the shaft, a link 11 having one end axially supported on the eccentric shaft 6 of the cam 9, and a sensor arranged around the cam 9 , For example, an optical sensor 12.

Here, the link 11 is rotatably connected to the gear ring 13 which is the one end part of the cup delivery apparatus 2 at the front end.

14 is the connecting shaft.

When the cam 9 rotates once, the gear ring 13 reciprocates as indicated by the arrow B by the reciprocating motion of the link 11, whereby the cup separating cam 3 has the first predetermined angle as described later. (E.g., approximately 180 degrees), that is, the cup 10 is ejected by rotating it at an angle sufficient to release one cup 10 separately.

Here, at the time of discharge of the cup, the gear motor 8 is stopped and controlled so that the cam 9 rotates one time whenever there is a cup discharge command.

This control is performed by the above-described cam 9, in which the above-described optical sensor 12 and the cutout portion 9a are formed in the outer circumferential portion, and the specific control thereof will be described with reference to FIG.

First, the relationship between the optical sensor 12 and the cam 9 is such that when the cam 9 rotates to shield the optical axis of the optical sensor 12 and reaches the cutout 9a of the cam 9, the shielding of the optical axis is released. The signal output from the optical sensor 12 changes.

And the signal of this optical sensor 12 is input into a control apparatus.

As shown in Fig. 4A, the cam 9 is placed in the standby position in the state where the optical sensor 12 is brought to the cutout portion 9a.

When the cup discharge command is issued, the motor output mo is output from the control device so that the gear motor 8 rotates forward, and the cam 9 rotates in the direction of the arrow shown.

As the cam 9 rotates, the signal So is output from the optical sensor 12 via the cutout portion 9a as shown.

Here, by detecting the fall of the sensor output when the optical sensor 12 reaches the cutting | disconnection part 9a again, a control apparatus stops an electric motor output and stops the gear motor 8.

As a result, the cam 9 rotates once and returns to the initial standby state as shown in (b) of the figure, and waits for the next cup discharge command.

In this case, the overall operation of the cup dispensing apparatus 2 returns to the atmosphere of a via states b and c, as shown in FIG.

Under such control, the cup separating cam 3 reciprocates to eject the cups 10 one by one.

By the way, the cup dispensing apparatus 2 corresponds to the lowest cup 10, and the several cup separation cam 3 and the cup separation cam 3 which rotated around it freely are arrange | positioned, and these cup separation cam 3 are rotating support shafts. The gear ring 13, which is provided for reciprocating movement as indicated by an arrow around the center 17, and the cup separation cam 3, are accommodated, and the gear ring 13 is freely rotated therein. It consists of a cylindrical outer case (18).

Here, the gearing 13 is provided with the tooth part continuously in the inner peripheral surface.

On the other hand, the cup separation cam 3 is provided with the tooth | gear 21 in the lower part, respectively, and the tooth | gear 21 is engaged with the tooth | gear part of the gear ring 13. As shown in FIG.

Therefore, when the gearing 13 makes one reciprocating motion by the drive device 7, the cup separating cam 3 reciprocates at a predetermined angle α in conjunction with it.

The cup separating cam 3 has a first toenail 19a and a second toenail 19b which are mutually different from the circumferential direction.

And in FIG. 3, when it rotates forward (clockwise), the 1st claw 19a will retract and the 2nd claw 19b will advance.

At this time, the second toenail 19b is squeezed in between the lowermost cup and each blade portion 22 of the next cup, thereby separating the lowermost cup 10 and maintaining the next cup.

When the first cup is rotated by the first predetermined angle and the lowest cup is released, the cup separating cam 3 is rotated counterclockwise to return to its original position.

In this reverse rotation, the second claw 19b retracts, the first claw 19a advances, and the next cup is held as the lowest cup.

The cup 19 is released by the operation of the first toenail 19a and the second toenail 19b of the cup separating cam 3, but in reality, the first toenails 19a and 19b are rotated together. Denoted by 10 by the movement to rotate slightly in the rotational direction thereof.

In this way, the cup 10 is discharged from the cup dispensing apparatus 2, and when the remaining cups become smaller, it is detected and shown, as shown in FIG. 1 from the cup storage column provided above the guide tube 1, although not shown. The cup is brought into the state of the row of the cups, and is dropped and replenished.

This replenishing cup 10A is normally stacked on the remaining cup 10B as shown in FIG. 2, and the cup 10 can be continuously discharged.

Here, as a configuration for replenishing the cup 10, for example, a microswitch for detecting the presence or absence of a cup in the guide cylinder 1 is arranged around the lower portion of the guide cylinder 1, and the actuator is guided. In the guide cylinder 1 through the window hole formed in the lower circumferential wall of (1), when the cup 10 is in the guide cylinder 1, the actuator is pushed by the cup and comes out of the guide cylinder. And the cup is lost in the guide cylinder 1, the actuator protrudes into the guide cylinder 1 and becomes "OFF". According to the "OFF" signal from this microswitch, the control unit operates the cup dispensing apparatus. What is necessary is to replenish 10A of replenishment cups.

By the way, as shown in FIG. 1, the replenishment cup 10A replenished in this way may be overwhelmed by the edge of the residual cup 10B, and may be clogged in the guide cylinder 1.

The present invention is characterized by dropping the hanging refill cup 10A to the normal position shown in FIG.

As described above, since the cup 10 rotates and falls when the cup separating cap 3 rotates at the time of discharging the cup, the cup 10 does not fall apart by using this operation. The remaining cup 10B is rotated forward / reversely by the control of forward / reverse rotation of the cup separation cam 3.

In this way, the hanging bottom cup 10A is shaken by the bottom and falls to a normal position.

Next, a control is performed to control the drive device 7 so that the cup separating cam 3 rotates at a second predetermined angle which is smaller than the first predetermined angle at which the cup separation cam 3 is normally rotated. A description with reference to FIG. 6 and FIG.

The cup release signal is output when the cup is replenished and the cup is clogged, and the gear motor 8 is rotated forward.

The drive output to the gear motor 8 is output via a control device.

When the cam 9 rotates forward in the direction of the arrow shown in FIG. 5, the sensor signal rises when a. Standby → b. Stop I in FIG.

The rise of this signal S1 is detected, and the control device stops the output m1 to the gear motor 8.

After the gear motor 8 is stopped once, a predetermined time t0 is set. This time, the inversion output m2 of the motor is output from the control device, and the gear motor 8 is rotated in reverse. When the cam 9 is slightly reversed in the direction of the arrow from the state of b. Midway stop I, the sensor signal is lowered, but the motor reverse output m2 is continued, and the cam 9 continues to rotate in reverse c. When the stop II occurs, the sensor output goes up again.

The rise of this signal S2 is detected and the control device stops the inversion output m2 to the gear motor 8.

After a fixed time t0 after the temporary stop of the gear motor 8, the forward rotation output m1 is again output from the control device to the gear motor 8 to rotate the gear motor 8 forward.

Then, when the cam 9 rotates slightly forward and reaches the d. Standby position where the light sensor 12 reaches the cutout portion 9a, the sensor signal goes down, and at the same time, the output m1 from the control device is stopped. d. Maintain the state of the atmosphere (a.

Here, in order to rotate the cam 9 from the stop I to the stop II, for example, a timer is operated by raising the signal S1 through the control device using a timer, and the motor reverse output (t0) is passed through (t0) time. It is sufficient to output the m2), stop the timer by raising the signal S2, and stop the motor inversion output m2.

In the same manner, even when the cam 9 is slightly rotated from the stop II to the atmosphere, the timer is operated by raising the signal S2, and after the time t0, the motor forward rotation output m1 is output. A short time operation timer may be used, such as stopping the timer by stopping the timer at S2).

Therefore, in FIG. 5, the forward rotation / reverse rotation operation of the cam 9 performed from a. Stand-by b. Midway stop I → c. Midway stop II rotates the cup separation cam 3 in the first clockwise direction. As shown in FIG. 6, a. Stand-by b. Stop midway I becomes, and the cup separation cam 3 then rotates back, and returns to b. Midway stop a.

At this time, the cup separating cam 3 is rotated at a rotational angle smaller than the first predetermined angle of rotation at the time of separating the cup, that is, the second predetermined angle, so that the remaining cup 10B is not separated from the cup 10B. I'm just reciprocating).

In addition, when the clogging release operation of the cup is operated when the cup is clogged, an optical sensor is disposed at the position shown by the dotted line above the guide tube 1 in FIG. It can be operated by using the output of the optical sensor until the refill cup 10A falls.

On the other hand, in the case where the cup 10 is made of plastic or plastic coated on the surface, the static electricity is easily charged, and therefore, when the cup 10 is separated, it is not easily released by sticking to the cup on it. If the cup activator, which is introduced into the product take-out hole, is also made of plastic, there is a problem that the cup 10 is caught by the glider during the fall.

Here, as shown in FIG. 3, two static electricity removal brushes 31 are mutually opposed and provided in light contact or proximity to the circumferential surface of the cup 10. As shown in FIG. As described above, the cup unblocking operation is performed, and the brush 31 and the cup 10 come into contact with each other to easily remove static electricity.

Here, conventionally, the brush is provided at an appropriate position, but the contact between the cup and the brush is only the longitudinal contact at the time of refilling the cup and the horizontal contact at the time of removing the cup, and the contact time is short.

On the other hand, according to this structure, by performing the above operation at the time of refilling the cup, the number of times of contact and the time of contact can be increased, and effective static electricity removal is performed. According to the present invention as described above, the remaining cup on the cam is rotated by rotating the cup separating cam of the cup dispensing device forward / reversely in a range irrelevant to the separation of the cup when the cup is refilled and the cup is refilled. Is rotated forward / reverse by the operation of the cam.

Therefore, the bottom surface of the refill cup which is stopped over the edges of these remaining cups is shaken, and the refill cup can be dropped to a regular position, and the clogging of the cup can be easily solved.

Moreover, the effect of unblocking a cup is performed using a normal cup delivery mechanism as it is, even if a part or mechanism which drops the clogged cup is not provided separately.
