Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a confectionery piece supply method suitable for a packaging machine that packages a plurality of confectionery pieces at once.

Conventionally, confectionery pieces supplied to packaging machines, etc., are packed in single pieces, although various high-speed feeding methods using assembly line operations that do not involve intermittent movement have been developed. When feeding multiple confectionery pieces at equal intervals to a packaging machine that simultaneously packages confectionery pieces in bulk, it is possible to perform low-speed feeding with intermittent motion, but smooth feeding at high speed is not possible. This was impossible, and a decline in work efficiency was inevitable. The object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to feed confectionery pieces to a plurality of confectionery pieces one after another to a feeding section at high speed and in a smooth flowing state without any impactful movement that tends to damage the confectionery pieces. In order to provide a method for supplying confectionery pieces, the structure thereof will be described in detail with reference to the illustrated embodiment as follows.

In the figure, 1 is an inner disk that is pivoted on the machine frame 51 and rotates horizontally, 2 is an outer disk that rotates horizontally around the outer circumference of the inner disk 1 at a faster speed than the inner disk, and the inner disk 1 is a variable speed motor. 3 through chain rings 4, 5, 6 and chain band 7, and outer disk 2 is driven by chain ring 8 with chain ring 5 axis, chain band 9,
It rotates in conjunction with the chain ring 10. 11 is a driving belt vehicle 1
2 and the knife edge 13 via an intermediate belt pulley 1 and a tension roller 15, and is driven by a motor 16 via a chain ring 17, a chain belt 18, a chain ring 19, and a driving belt pulley 12. , the confectionery piece sending end faces the confectionery piece receiving position 20 along the radius line on the inner disk 1, 21 is designed to prevent the confectionery piece a on this belt 11 from falling over when it is sent out onto the disk 1. Installed confectionery piece receiving board, 2
2 and 22'' are light emitting and light receiving confectionery piece detectors installed on both sides of the confectionery piece sending end of the conveyor belt 11, and 23 is installed on one side of the confectionery piece receiving position 20 along the radius line on the inner disk 1. A confectionery piece detector 23 detects the confectionery pieces delivered from the conveyor belt 11 to the confectionery piece receiving position 20 on the disk 1, and at the same time detects the confectionery pieces at the confectionery piece delivery end of the belt 11. , 22'', the signal causes the conveyor belt 11 to be stopped via the motor 16, and the detector 22,
Detector 23 on disk 1 even if there is a candy piece a at 22''
The motor 16 continues to rotate if there is no piece of sweets at the position A, and the signal of this detector 23 is kept constant by a timer even after the piece of sweets a detected at the receiving position 20 on the disk moves. time, that is, the next horizontal row of confectionery pieces to be fed. The switching time of this timer is changed to long or short depending on the disc driving speed of the variable speed motor 3, and the timer is set so that the confectionery pieces 2 do not form two rows on the disc 1 with the previous row of confectionery pieces 2. If 3 is not fast enough, the timer of the detector 23 will shorten and the pieces of sweets will become yen. As the disk 1 rotates, more confectionery pieces enter the disk, and as the disk slows down, the timer also becomes longer so that pieces of sweets enter the disk at a slower tempo.

Next, at 25, the confectionery pieces sent from the conveyor belt 11 onto the inner disk 1 ride on the disk in one horizontal row along the radius line of the disk. It is a guide plate that guides the top of the disk 1 toward the outer circumference of the disk eccentrically with respect to the circumference and sends it out onto the outer disk 2 in a vertical line, and is attached to the mounting bracket 26 with a set screw 27. There is. Reference numerals 28 and 29 are mounting brackets 30 which respectively serve as alignment guide plates for confectionery pieces rotating on the outer disk 2.
, 31 with set screws. 32 is a distribution plate for distributing the confectionery traveling in a vertical line on the outer disk 2 to the left and right, and its base is attached to a mounting frame 34 by a support shaft 33. A motor 37 supports a cam roller 36 on a connecting rod 35 in the midsection.
The cam grooves 39, 39'' of the cam 38 driven by the cam 38 guide the cam 38 to swing from side to side.The timer 40, 41 sets the stopping time of the distribution plate 32 at the oscillating position. This is a detector that outputs a stop signal, and the relationship between this detector and the distribution plate 32 is such that the cam 38 normally stops the distribution plate 32 for 5 seconds on the cam groove 39 side and 5 seconds on the cam groove 39'' side.・The detector's timer works to rotate the motor intermittently so that the

42 and 43 are parallel conveyance paths for confectionery pieces, and the distribution plate 3
2. Transfer the divided confectionery pieces to the introduction section 42'', 4 on the outer disk 2.
It is designed to be fed through the 3".

44 is a conveyor belt that receives the confectionery pieces fed into parallel conveyance paths 42 and 43 and conveys them along the conveyance path, and is stretched between belt wheels 45 and 46 and is driven by a motor 47.
is driven by a chain ring 48, a chain band 49, a chain ring 50, and a belt pulley 45.

Denoted at 52 and 53 are confectionery piece detectors installed in the intermediate portions of the conveyance paths 42 and 43, respectively, and when there is no confectionery piece a in one of the conveyance paths, for example, the conveyance path 43, the detector 5
3 sends the detection signal to the timer of the detector 41 of the distribution plate 32 to lengthen the stop time of the distribution plate on the detector 41 side (for example, the operation of the motor 37, which has been repeated at 5 second intervals, is increased). , the distribution plate 32 is 108 on the detector 41 side.
When there are no more confectionery pieces in the conveyance path 42, the signal from the detector 52 is sent to the cam of the sorting plate 32 via the timer of the detector 40. The stop time on the groove 39'' side is lengthened to feed more confectionery pieces into the conveyance path 42, and when there are no confectionery pieces on both conveyance paths, a signal indicating the shortage of confectionery pieces is sent to the variable speed motor 3.
The information is then sent to the timer of the detector 23 to speed up the rotation of the disks 1 and 2 and feed more confectionery pieces on the conveyor belt 11 onto the inner disk 1.

54 is a confectionery piece feeding path for supplying confectionery pieces to a confectionery piece supply unit (not shown) such as a packaging machine, and is parallel to the parallel conveyance path 4.
The parallel confectionery pieces delivered from the delivery ends of Nos. 2 and 43 on the conveyor belt 44 are received by the side wall 55 of this feeding path, and are pulled out laterally by a pushing rod 56 that advances along the feeding path and supplied. It is sent in bulk to the department.

Now, the confectionery pieces a arranged randomly on the conveyor belt 11 as shown in FIG.
They are sent out in a substantially single row horizontally on the disk 1 and rotate in the rotational direction of the disk while remaining in a single horizontal row. During this time, when the detector 23 detects a confectionery piece at the receiving position on the disk 1, and at the same time a confectionery piece is detected by the detectors 22, 22'' at the delivery end of the conveyor belt 11, the signal of the detector 23 is activated by a timer. Since the saw motor 16 is stopped for a fixed period of time, the conveyor belt 11
The upper confectionery pieces do not need to be lined up neatly, and even if there is a distance between them and the next confectionery piece, they will catch up with each other at the end of the belt, and the confectionery pieces will be delivered onto the disk 1 at regular intervals. be done. Next, the horizontal rows of confectionery pieces that rotate on the inner disk 1 are guided by the guide plate 25 during their rotation, so that each confectionery piece eccentrically moves along the disk in the outer circumferential direction by 1 vertical direction with respect to the direction of rotation.
The confectionery pieces are fed from the outer periphery of the disk 1 onto the outer disk 2 while moving into rows, but since the disk 2 rotates faster than the disk 1, the confectionery pieces are elongated from front to back and placed onto the outer disk 2. The confectionery pieces are transferred and rotated at regular intervals on the disk 2, and in the case of long confectionery pieces, they are guided by guide plates 28 and 29 and transferred in a single vertical line with their orientation aligned in the longitudinal direction. However, on the way, the vertical confectionery pieces of the lever are distributed equally to the left and right by the distribution plate 32, and are transferred to the parallel conveyance paths 42, 43 at the introduction portions 42'', 43.
The confectionery pieces are introduced through the conveyor belt 44 and translated into two rows in front and behind each other in the conveyance path, and then are sent out from the delivery end to the feed path 54.The confectionery pieces sent out at this time are transferred to The conveyor belt 44, which is being driven by
At the same time as the next confectionery piece is pulled out to the side by Road 42,4
The confectionery pieces in 3 are passed from the side wall 55 of the feeding path to the detector 52,
If the confectionery pieces do not extend into two rows after paralleling until around 53, the process will not be carried out smoothly. Therefore, when the confectionery pieces on either the conveyance path 42 or 43 run out, the detection signal from the detector 52 or 53 will be transmitted to the distribution plate 32. This signal is sent to the timer of the detector 40 or 41, and the movement of the motor 37 changes, causing the distribution board to stop for a longer time on the side that sends the confectionery pieces to the conveyance path where the confectionery pieces are missing. The number of confectionery pieces sent to the conveyance path increases, and the two rows of confectionery pieces in the conveyance paths 42 and 43 are balanced. When there are no confectionery pieces left on both conveyance paths, a signal indicating the shortage of confectionery pieces is sent to the variable speed motor 3 and the timer of the detector 23 on the disk 1, and the motor drives the disk 1,
2 becomes faster, and more confectionery pieces on the conveyor belt 11 are sent onto the inner disk 1. Thus, the amount of confectionery pieces increases and the confectionery pieces accumulate up to the detectors 52, 53 on the conveying paths 42, 43. and the speed of discs 1 and 2 and conveyor belt 1
The frequency of sending out confectionery pieces in No. 1 becomes lower. Furthermore, the detectors 52,5
If the confectionery piece does not come even after 3 sends a signal that there is no confectionery piece, the operation will stop after a few seconds. The present invention uses a variable speed motor to drive the inner disk that rotates horizontally as described above and the outer disk that rotates its outer periphery in conjunction with the same direction at a faster speed than the inner disk. The confectionery pieces are sent out one after another in approximately one horizontal row from the delivery end of the conveyor belt to the confectionery piece feeding position along the conveyor belt, and the confectionery pieces of this row are rotated on a disk by a guide plate eccentrically with respect to the circumference of the rotation. While guiding and sending out the disk in a vertical line in the direction of the outer circumference, it is transferred from the outer circumferential edge of the inner disk to the outer disk at equal intervals, and then it rides on the outer disk and rotates in a vertical line. The confectionery pieces are distributed into equal parts by a distribution plate whose distribution operation is controlled by a timer set in a detector.The confectionery pieces are introduced from the disk into multiple rows of parallel conveyance paths, and then transferred to each conveyance path. A plurality of parallel confectionery pieces simultaneously delivered to the confectionery piece feeding path from the delivery end of the confectionery piece feeding section are sequentially fed along the feeding path to the confectionery piece supply section, and during this time, the confectionery piece delivery position on the reto in the conveyor tray; A detector detects the presence or absence of a confectionery piece at the confectionery piece receiving position on the inner disk, and if a confectionery piece is detected at both positions simultaneously, the signal is transmitted for a predetermined time corresponding to the disk drive speed of the variable speed motor. By stopping the drive motor of the conveyor belt while being maintained by a timer, a fixed amount of confectionery pieces are delivered from the conveyor belt onto the inner disk at regular intervals, and also at an intermediate position of the parallel conveyance path. detects the presence or absence of confectionery pieces in each conveyance path, and if there is no confectionery piece in any of the conveyance paths, the signal is sent to the timer of the detector on the sorting plate, and the side opposite to the conveyance path with no confectionery pieces is sent. The amount of confectionery pieces on each conveyance path is balanced by increasing the stopping time of the sorting plate, and if there are no confectionery pieces on each conveyance path, the signal is sent to the variable speed motor and the timer of the detector on the inner disk. Since the conveyor disk rotates quickly and the amount of confectionery pieces sent onto the disk is increased, the confectionery pieces randomly arranged on the conveyor belt can be quickly and reliably moved in a smooth flowing state without shocking movement. It is now possible to align and separate confectionery pieces into multiple rows of parallel flow and supply confectionery pieces destined for multiple pieces to the confectionery piece supply unit at equal intervals, thereby simultaneously packaging confectionery pieces destined for multiple pieces. If used to supply confectionery pieces to packaging machines, etc., it will not only improve the work efficiency, but also enable smooth feeding operations at high speed even for confectionery pieces whose surfaces are easily damaged, such as chocolate and cream. It is something that can be learned.
