Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating block pieces such as confectionery pieces into individual pieces and supplying them to a downstream conveyor at equal intervals.

[0002]

2. Description of the Related Art A device for separating and supplying block pieces such as confectionery pieces that have been unevenly thrown into each piece is disclosed in JP-B-58-2.
The one disclosed in Japanese Patent No. 7164 has already been proposed. As shown in FIG. 1 and FIG. 2, this one has a flat bottomed cylindrical separation case (19), a rotating disc (1) which rotates inside thereof,
Further, it is composed of a conveyor (2) disposed close to the lower side of the separation case (19).

An opening (11) is provided on the peripheral edge of the rotating disk (1).
(11) is cut at regular intervals and the rotating disc
A block discharge port (12) facing the conveyor (2) from above is opened and cut in the outer peripheral portion of the separation case (19) accommodating (1). In this product, when block pieces (A) (A) such as confectionery pieces are continuously and irregularly put on the rotating disc (1) from a hopper (not shown), the block pieces (A) (A) are rotated. Disk
It is gradually moved to the peripheral edge portion by the centrifugal force accompanying the rotation of (1) and is accommodated in the open portions (11) and (11). Then, the open part (1
1) Block pieces (A) (A) housed in (11) are rotating discs.
With the rotation of (1), the block outlet (1
When it is carried to the part of 2), the block outlet (1
It is dropped from 2) to the conveyor (2) below and is supplied to the downstream side.

However, in the above-mentioned conventional one, the block pieces (A) (A) which are arranged and supplied on the conveyor (2).
However, there is a problem that the intervals are easily non-uniform and the smooth progress of the work such as the boxing process on the downstream side of the conveyor (2) is hindered. The above problems will be described in more detail. Conveyor
The rotating disk (2) and the rotating disk (1) are driven at a predetermined speed by a conveyor driving device (29) and a disk driving device (3) respectively corresponding to them. That is, the block outlet (12) formed in the separation case (19) has a specific opening (1) of the rotating disc (1).
The conveyor (2) travels a predetermined distance while the rotary disc (1) rotates by one pitch from the time when 1) matches until the time when the next open part 11 matches. It is configured like this.

However, when the power supply voltage supplied to the conveyor drive device (29) or the disc drive device (3) fluctuates, or when noise is mixed in these control circuits, the conveyor (2 ) And the relative speed of the rotating disk (1) change, and both do not operate properly in synchronization. That is, even if the conveyor (2) travels for a predetermined alignment interval of the block pieces (A) (A), the rotating disc (1) opens the opening (11) (1
In some cases, it does not rotate exactly by 1 pitch in 1). Then, when the power supply voltage continues to fluctuate, the block pieces (A) (A) are left in a state in which the alignment intervals of the block pieces are misaligned, which allows work such as box packing on the downstream side. Will not proceed smoothly.

The present invention has been made in view of the above-mentioned points. "The rotating disk (1) having open portions (11) (11) formed at regular intervals on the periphery, and the open portion (11) ) (11) is equipped with a block discharge port (12) provided between a specific point in the turning locus and the conveyor (2) located below it, and the block is put on the rotating disc (1). Separation and supply device for block pieces, in which the pieces (A) (A) are moved to the outer peripheral side by the centrifugal force of the rotating disk (1) and accommodated in the open parts (11) (11)
Even if the supply timing of the block piece (A) to the (2) is deviated, this can be corrected so that the work on the downstream side such as box packing can be smoothly performed.

[0007]

[Technical Means] The technical means of the present invention for solving the above problems will be described with reference to the conceptual diagram shown in FIG.
"Rotation amount measuring device (17) that outputs a signal corresponding to the rotation angle of the rotating disk (1), an odometer (21) that measures the mileage of the conveyor (2), and the odometer ( 21) Take the ratio of the output of the rotation amount measuring device (17) to the measured distance, and if it matches the predetermined reference ratio, output the standard speed request signal and the former ratio is larger than the reference ratio. In the case where the low speed request signal is output, conversely, when the former ratio is smaller than the reference ratio, a high speed request signal is output.
(18), and the above odometer (2) for a predetermined reference interval as the alignment interval of the block pieces (A) and (A) on the conveyor.
A conveyor monitoring device (25) that outputs a synchronization signal each time the conveyor travel distance measured in 1) is provided, and a speed signal output device (18) when the synchronization signal is output from the conveyor monitoring device (25).
Is operated to control the rotation speed of the rotating disk (1) according to the output of the speed signal output device (18). "

[0008]

The above technical means operates as follows. The mileage of the conveyor (2) is measured by the odometer (21),
The distance measured by the odometer (21) is a block piece on the conveyor.
(A) A synchronization signal is output from the conveyor monitoring device (25) every time the alignment interval of (A) is increased by a predetermined reference interval.

On the other hand, the rotation amount measuring device (17) outputs a signal corresponding to the rotation angle of the rotating disc (1).
The speed signal output device (18) calculates the ratio between the rotation amount of (1) and the traveling distance of the conveyor (2) measured by the odometer (21). Then, the speed signal output device (18) outputs a synchronization signal from the conveyor monitoring device (25) and each time it is determined that the conveyor (2) has traveled by the alignment interval of the block pieces (A) (A). Be driven by.

Then, the speed signal output device (18) causes the rotation amount (rotation amount measuring device (17) of the rotary disc (1) with respect to the travel distance of the conveyor (2) measured by the odometer (21). (Measured quantity)
To determine the ratio of. Then, when the ratio matches the predetermined reference ratio, the conveyor (2) is a block piece.
(A) The conveyor while traveling for the alignment interval of (A)
Since the traveling distance of (2) and the rotation amount of the rotating disk (1) maintain an appropriate relationship, the speed signal output device (18) outputs a standard speed request signal and the rotating disk (1) outputs Maintain the current speed of rotation. If the ratio of the rotation amount of the rotating disk (1) to the above-mentioned travel distance of the conveyor (2) (measurement distance of the odometer (21)) is larger than the above-mentioned reference ratio, the conveyor (2)
On the other hand, since the operation of the rotating disk (1) is ahead of the proper value, the speed signal output device (18) outputs a low speed request signal.
That is, the rotation speed of the rotating disk (1) is slightly lowered. As a result, the ratio of the rotation amount of the rotating disk (1) to the traveling distance of the conveyor (2) approaches the above-mentioned reference ratio. Further, when the ratio of the rotation amount of the rotating disc (1) to the traveling distance of the conveyor (2) is smaller than the above-mentioned reference ratio, the operation of the rotating disc (1) is appropriate for the conveyor (2). Since it is behind the value, the speed signal output device (18) outputs a high speed request signal to slightly increase the rotation speed of the rotating disk (1). As a result, also in this case, the rotation disc (1) is moving so that the rotation amount of the rotation disc (1) with respect to the traveling distance of the conveyor (2) approaches the reference ratio as in the above case. Adjust the speed of the disc (1). Then, as described above, the adjusting operation is executed every time the conveyor (2) travels by the alignment interval of the bus block pieces (A) (A) by the synchronization signal output from the conveyor monitoring device (25).

As described above, according to the above technical means, when the rotating operation of the rotating disk (1) with respect to the traveling operation of the conveyor (2) is slowed, the rotating disk ( The speed of the rotating disk (1) is adjusted so that the ratio of the rotation amount of 1) is kept at the reference ratio.

[0012]

[Effect] The present invention has the following unique effects. Block piece
(A) The rotating disc (1) is arranged so that the rotation amount of the rotating disc (1) becomes constant every time the conveyor (2) runs for the alignment interval of (A).
Since the rotation speed of the rotating disk is adjusted, even if the operation amount of the rotating disk (1) or conveyor (2) fluctuates temporarily due to fluctuations in the power supply voltage, the block pieces (A (A) The alignment interval in (A) is immediately corrected and the interval returns to a constant value.

Next, a control program having the contents shown in the flow chart of FIG. 7 is stored in the microcomputer 68, and the operation of the apparatus of this embodiment will be described below with reference to FIG. The conveyor (2) is independently driven by a driving device (not shown). (A). In the steps indicated by reference numerals (71) to (73), the first
~ Which of the third pattern switches (63) to (65) has been operated is determined. Then, when the first pattern switch (63) is operated, the value of the first variable I is set to "0" in the step of the drawing symbol (74), and when the second pattern switch (64) is operated. When the value of the first variable I is set to "1000" in the step of the drawing code (75) and the third pattern switch (65) is operated, the drawing code (76)
In the step of, the value of the first variable I is set to "2000". (I). Next, the operation shifts to the step of the drawing symbol (77) and the closing of the start switch (66) is monitored, and the start switch (6
When 6) is input, execute the step of drawing code (78),
The slit (40) formed in the positioning disc (4) is the sensor (41).
Rotate the rotating disc (1) until it faces to adjust the zero point. That is, in this state, each memory in the microcomputer 68 is cleared. Also, the conveyor counter (26) is reset. (C). Next, in step 79 of the drawing code, both the second variable K and the third variable L are set to "0". The second variable K is the number of pulses output by the pulse generator (23) while the conveyor (2) travels for a predetermined alignment interval of the block pieces (A) (A) on the conveyor. It has the function to show. In this embodiment, the pulse generator (2) is moved while the conveyor (2) is running for the alignment interval of the block pieces (A) (A).
3) is set to output a pulse of "60", and 60 is output while the conveyor (2) travels for the above-mentioned alignment interval.
The control signal is output to the pulse motor (M) only once. Then, in this embodiment, the second variable K
The function unit in the microcomputer for determining that the number has increased to "60" is the conveyor monitoring device (2
It corresponds to 5). Further, the third variable L is a positioning disc
After "0 point adjustment" by (4), block outlet (12)
It has a function of indicating the number of passages through the opening (11). (D). The control operation is moved to the step of drawing code (80),
Conveyor counter (26) showing the distance traveled by the conveyor (2)
Is compared with the output of the pulse motor counter (28) that measures the rotation angle of the pulse motor (M) that drives the rotating disk (1). In the step, the fifth variable M is set to "0". In this embodiment, the pulse motor (M) is "360
The number of pulses of "0" is output, and this is measured by the pulse motor counter (28). In this embodiment, the rotating disc (1) is also configured to rotate once while the pulse motor (M) makes one revolution, and the rotating disc (1) is formed on the outer periphery of the rotating disc (1). 60 open parts (11) (1
When it is moved by 1 pitch of 1), the count number of the pulse motor counter (28) is increased by 60. (E). Next, the step of drawing code (82) is executed to store the output of the conveyor counter (26) indicating the current traveling distance of the conveyor (2) in the belt traveling distance memory A, and to display "4th variable J = A-60 × L ”. That is, since "L = 0" until the first opening (11) coincides with the block outlet (12), the fourth variable J in such a case is the conveyor counter at the present time.
The count number of (26) (the number of pulses output by the pulse generator (23) along with the traveling of the conveyor (2)), that is, the stored value of the belt traveling distance memory A, coincides. Therefore, the first pattern switch (63) is operated to set the first variable I to "0", but the output of the conveyor counter (26) indicating the traveling distance of the conveyor (2) and the pulse motor When the output of the pulse motor counter (28) that indicates the rotation angle of (M) matches and the fifth variable M is "0", "I + J"
"+ M" is "output of conveyor counter (26) (value of A)"
Is equal to That is, the pulse generator (2
Every time (3) outputs one pulse and the measured value of the conveyor counter (26) increases by "1", the above "I + J + M" increases by "1".

Therefore, in the step of the drawing code (83), the number of pulses indicated by the data stored in the memory at the address "I + J + M" in the table (T) is applied to the pulse motor.
When outputting to (M), the address corresponding to the count number of the conveyor counter (26) is specified, and the number of pulses indicated by the data stored in the memory of the specified address is the pulse motor.
It will be output to (M). That is, 0 of table (T)
The data stored in the memory from the address to the address 59 is sequentially read by the CPU, and the number of pulses indicated by each data is sequentially output to the pulse motor (M).
Then, as shown in the step of the drawing code (84), each designated address (address for designating each memory of the table (T))
Increases every time the pulse generator (23) generates a pulse and the output of the conveyor counter (26) increases by "1", and the operation becomes 60 by increasing the second variable K by one. (See steps in drawing code (84) (85)). As a result, the rotary disc is rotated by one pitch of the open parts (11) (11).
The speed control of the rotating disk (1) is executed while the (1) is rotating, and the speed change of the rotating disk (1) is controlled by the table.
The speed indicated by the data stored at addresses 0 to 59 of (T), that is, the speed change of the rotating disk (1) is changed like a sine wave curve (53) in the above case. Then, when the specific opening portion (11) coincides with the block discharging portion (12), the block piece (A) accommodated in the opening portion (11).
Is dropped onto the conveyor (2) via the block discharge section (12) and is sent to the downstream side. (F). Next, at the step of the drawing code (86), it can be confirmed that the value of the second variable K has become "60", and the open part (1
1) If it can be determined that the rotary disk (1) has rotated by one pitch of (11), the second variable K is entered in the step of drawing code (87).
The value of is set to "0" and the block outlet (12)
In order to recollect the number of open parts (11) that have passed through
1 ”is calculated. (Ki). Then, when the value of the third variable L has not reached 60, which is the number of the open parts (11), that is, the drawing symbol (88).
When "3rd variable L = 60" is not reached when the step of step 1 is executed, the output of the conveyor counter (26) and the pulse motor counter (28) indicating the rotation angle of the pulse motor (M) are displayed again. The control operation is transferred to the step of drawing code (80) for comparing with the output. And conveyor counter (26)
If the output of the pulse motor counter (28) is smaller than that of the pulse motor and the rotation of the rotating disk (1) is behind the schedule, the value of the fifth variable M is executed after the step of drawing code (90) is executed. Is set to 60. As a result, as shown in FIG.
The high speed data (57) stored in the table (T) of the OM (62) can be designated. That is, when the step of drawing code (83) is executed, the address "I + J + M" of the table (T)
Is specified in the range of "addresses 60 to 119 (when I = 0)". Then, since the data for increasing the rotation speed of the pulse motor (M), that is, the rotating disk (1) is stored in the memory of the adrel range as compared with the standard speed data (56), the conveyor (2) The amount of rotation of the pulse motor (M), that is, the amount of rotation of the rotating disk (1), increases during the movement of the block pieces (A) (A) by a predetermined alignment interval. As a result, when the rotating operation of the rotating disk (1) is behind the traveling operation of the conveyor (2), the delay can be corrected, and the rotating disk (1) and the conveyor are
The operation of (2) can be synchronized.

Further, when the rotating operation of the rotating disk (1) is ahead of the traveling operation of the conveyor (2) when the steps of the drawing codes (80) and (90) are executed, the drawing code (92) ) Step, the fifth variable M is set to "120", and the low speed data (58) that stores the data for reducing the rotation speed of the pulse motor (M), that is, the rotation speed of the rotating disk (1). To be specified.

Thus, according to the above embodiment, the opening portion
(11) Every time the rotating disk (1) rotates by one chipp of (11), it is judged whether or not the rotating disk (1) and the conveyor (2) are in synchronization with each other. I try to take. (H). Finally, when the content of the third variable L is "60" which is the number of the open parts (11) and (11) when the step of the drawing symbol (88) is executed, that is, the rotating disc ( When it is confirmed that 1) has completed one rotation, the third variable L is reset to 0 in the step of drawing code (89) and the control operation is returned to the step of drawing code (80) again. Then, the output of the conveyor counter (26) that counts the number of pulses of the pulse generator (23) for the conveyor (2) and the output of the pulse motor counter (28) that indicates the rotation angle of the pulse motor (M) Again, it starts to increase sequentially from "0" to "3599", and the same operation as above is executed.

In the above embodiment, the second variable K
The value of "60" and the predetermined block piece (A)
Each time the conveyor (2) travels for the alignment interval of (A), the rotation amount of the pulse motor (M), that is, the rotary disk (1) is changed by the conveyor (2).
The functional unit in the microcomputer to be compared with the traveled distance corresponds to the speed signal output device (18) described in the technical means section.

In the above embodiment, the conveyor counter (2
Both 6) and the pulse motor counter (28) count up to 3599, but the maximum values that can be counted by both do not necessarily match. That is, the counter for the pulse motor when the rotating disc (1) makes one revolution
The output of (28) is a constant multiple of the output of the conveyor counter (26), and the output value of the conveyor counter (26) is multiplied by a constant value, whereby the roller for the conveyor (2) ( 2
The number of pulses input into the microcomputer when 4) makes one rotation may be equal to the number of pulses input into the microcomputer when the pulse motor (M) makes one rotation.
