BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for separating and supplying rectangular parallelepiped block pieces such as confectionery pieces.

[0002]

2. Description of the Related Art As a method and apparatus for separating and supplying block pieces such as confectionery pieces that have been thrown in unevenly one by one, the one disclosed in Japanese Patent Publication No. 58-27164 has already been proposed. As shown in FIGS. 1 and 2, the confectionery pieces as block pieces (A) and (A) continuously and irregularly put on the disc (1) from a hopper (not shown) are Disc (1)
Each of the open parts (11) (11) provided on the peripheral edge of the disk is housed in a fixed posture one by one, and as the disc (1) rotates, the discharge part
The block pieces (A) and (A) transferred to the (12) and discharged from the discharge section (12) to the discharge path (2) are kept in a fixed position and in a predetermined position by the transfer means of the discharge path (2). It is transferred at a predetermined interval.

In this prior art, since the disc (1) is surrounded by the annular side wall (10) and the disc (1) is formed into a conical shape, the disc (1) is separated from the hopper. The block pieces (A) and (A) thrown into the center part unevenly and continuously are gradually moved to the peripheral part by the centrifugal force as the disc (1) rotates, and the open part (11) ) It is thrown into (11). At this time, it moves from the central part of the disc (1) to the peripheral part and the open part (11)
In this prior art, the rotation speed of the disk (1) is not uniform and the rotation speed is periodic so that the block pieces (A) and (A) can be housed separately and smoothly in (11).

It will rotate only 0/60). Next, when the data of the next addresses 60 to 119 are output, the speed change for one cycle of the sine curve (53) is executed while the disk (1) rotates by 6 ° C. again, and the speed change is 3599. Repeat the process until the address data is output to the variable speed motor (M).
As a result, the disc (1) continues to rotate while changing the speed as shown in FIG. In this case, the table (T) storing the data group showing the speed change shown in FIG. 7 corresponds to the output signal setting device (C) described in the section of the technical means.

When the start switch (64) is operated after the second pattern switch (62) is turned on, the data of addresses 10000 to 13599 of the table (T) are selected, and the disk (1) is a triangular wave. Change the speed as shown in (54). or,
If the start switch (64) is operated after the stop switch (65) is turned on, it will be 23599 from the address 20000 of the table (T).
The data up to the address is selected, and the disk (1) changes its speed like a microcomputer (5).

Further, as shown in FIG. 10, the high speed rotation range (T1
It is also possible to adopt a configuration in which the cycle S as the sum of the time of 1) and the low speed rotation range (T12) changes with time. In this case, after the value of the cycle S gradually increases from the first cycle S1 to the second cycle S2 to the third cycle S3, the value of the S cycle becomes the third cycle.
It is also possible to perform stable control in the cycle S3. To this end, a disk (52) in FIG.
It is only necessary to store the data group necessary for changing the swing rotation speed of (1) with time. That is, the table (T) of the ROM (52)
In the above, the number of addresses allocated to the high speed rotation range (T11) of the second cycle S2 is made larger than the number of addresses allocated to the high speed rotation range (T11) of the first cycle S1, and further the third cycle S
Set the high speed range (T11) of 3 to a large value. Furthermore, the number of addresses assigned to the low speed rotation range (T12) of the first cycle S1 is second
While increasing the number of addresses assigned to the low speed rotation range (T12) of the cycle S2, the low speed rotation range (T12) of the third cycle S3 is further increased.
