This invention was made in response to the above-mentioned demands, and the object is to provide a pouch feeder that can reliably and quickly feed out a large number of loose pouches one by one without damaging them. .

[Key points of the invention]

In order to achieve the above-mentioned object, this invention sequentially sends out a predetermined amount of sachets packed with contents such as an oxygen absorber, desiccant, and condiments from a delivery trough in response to vibrations of a vibrator. The small bags are received by the receiving part, and the received small bags are sucked one by one by a suction device and sent out.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of the pouch inserting machine. This pouch feeder is equipped with an equipment case 1 and an alignment device 2 and a delivery device 3.The arrangement device 2 is arranged to arrange and send out a large number of small bags one after another, and the delivery device 3 is an arrangement device. The small bags sent out from No. 2 are sent out one by one.

The feed hopper 4 is provided with a delivery trough 6 (and first, second, third, and fourth detectors 7,8,9,1o). The pouch is placed in the upper part of the equipment case 1 via a vibrator 11, and according to the vibration of this vibrator, the pouch is sent in the direction of the arrow (to the right of the equipment case 1), and the right end is guided. It is designed to be sent into chute 12.

In this case, the first detector 7 is arranged above the tip side (right end side in the figure) of the supply hopper 4. This detector 7 detects the amount of sachets in the supply hopper 4, and is equipped with a light emitter and a light receiver, and reflects the light from the light emitter on the upper surface of the supply hopper 4, and receives this reflected light with the light receiver. By doing so, the amount of sachets passing through the area is detected. Also,
The vibrator 11 that vibrates the supply hopper 4 is provided with a coil Ilb on a base member 11a and a leaf spring 1.
The core 11d is provided through 1c and 110,
The alternating magnetic field generated in the coil 11b causes the core 114 to quickly approach and separate, thereby vibrating the supply hopper 4. By controlling the alternating magnetic field generated in the coil 11b, the feed rate of the supply hopper 4 can be controlled. Note that the base member 11a is the equipment case 1.
It is attached to the upper part of the body via an i-member (not shown) such as a coil spring.

The small quantity supply trough 5 is to which small bags are fed from the supply hole '84 via the guide chute 12, and is arranged at the right end side in the equipment case l, and the small quantity supply trough 5 feeds the small bags in small amounts in the direction of the arrow according to the vibration of the vibrator 13. (5 locations in the diagram). A second detector 8 is arranged above this small supply trough 5 . This second detector 8
is constructed in the same manner as the first detector 7 described above, and is adapted to detect the amount of sachets on the small quantity supply trough 5 and to control the feeding of the supply hopper 4. In addition, the vibrator 13 that vibrates the small amount supply trough 5 has a coil 13b fixed to the base member 13a with bolts 130, and a trough mounting member 13 via the plate spring 13 (1% 13d).

That is, by preventing the small amount supply trough 5 from lateral vibration, the detection accuracy of the second detector 8 described above is improved.

The delivery trough 6 receives the small bags from the small quantity supply trough 5, and is placed in the center of the equipment case 1. The delivery trough 6 is arranged in the center of the equipment case 1, and is arranged in a line according to the vibration of the vibrator 14, and sequentially moves in the direction of the arrow (left side in the figure). ). In this case, the delivery trough 6 is integrally formed with a receiving part 6a that receives the small bags from the small R supply trough 5, and an alignment part 6b that arranges the small bags sent out from the receiving part 6 in a line and sequentially sends them out. be. That is, the receiving part 6a is shaped like a landing and is formed slightly larger than the tip of the small quantity supply trough 5, and regulates the amount and direction of the pouches sent to the alignment part 6b.
This makes it easier to line up the sachets. Further, the alignment section 6b is for arranging the pouches in a line, and has the shape of an elongated gutter, the bottom surface of which is inclined in the lateral direction, that is, in the direction perpendicular to the direction in which the pouches are fed. As a result, the pouches are fed out in a line along the lowermost part of the bottom surface of the alignment section 6b.

Note that the vibrator 14 that vibrates the delivery trough 6 is configured in exactly the same manner as the vibrator 13 of the small amount supply trough 5 described above, and is placed on the mounting base 15b.

Additionally, above the delivery trough 6 are third and fourth detectors 9.
．． 10 are provided. The third detector 9 detects the small device above the receiving part 6 of the delivery trough 6, and controls the feed amount of the small quantity supply trough 5 to regulate the pouches on the receiving part 6a to a certain level. It has the same configuration as the first detector 7 described above. Further, the fourth detector 10 detects the amount of pouches on the aligning section 6b and controls the feed amount of the delivery trough 6 to send the pouches on the aligning section 6b at regular intervals. It has a similar configuration.

On the other hand, the delivery device 3 that sends out the pouches one by one from the delivery trough 6 includes a receiving part 16, a suction device 17,

The receiving portion 16 receives the small bags sequentially fed from the delivery trough 6 in an inclined state, and is shaped like a gutter with a stepped portion 16a, and is arranged in the equipment case 1 in an inclined manner. Transparent windows (not shown) are formed on the upper and lower sides of the stepped portion 16a in the receiving portion 16, and fifth and sixth detectors 19. 20 are provided. The fifth detector 19 detects whether or not the pouch is received above the stepped portion 16a and controls the feed amount of the delivery trough 6.
A light receiving body 19b is disposed below the light receiving body 9a, and the light receiving body 19b receives the light from the light emitting body 191L through a transparent window, thereby detecting whether or not the pouch is received. Further, the sixth detector 20 detects whether or not a pouch is sent out from above the stepped portion 16a by a suction device 17, which will be described later. However, there is a photoreceptor 20 below.
b are arranged respectively, and by receiving the light from the light emitting body 20a through the light transmitting window with the light receiving body 20b, it is detected whether or not the pouch has passed through the light receiving body 20b.

The suction device 17 sucks one pouch received on the stepped portion 16a of the receiving portion 16 and sends it downward.
It includes a suction pipe 21, a vacuum pump 22, a motor 23, a detachment plate 24, and the like. The suction tube 21 reciprocates above the stepped portion 16a to absorb the pouch on the stepped portion 16a, and the vacuum pump 22 is connected to a vinyl hose 2.

The pouch is detached against the suction force, and the detached pouch falls below the stepped portion 16a of the receiving portion 16. Incidentally, the dropped pouch is sent into the chute section 18 through the receiving section 16.

The chute section 18 temporarily stores one pouch sent out from the receiving section 16 by the step device 17 and discharges it based on a discharge command signal, etc., which will be described later. It is disposed obliquely at the rightmost end inside the equipment case 1, and its lower end protrudes to the outside of the equipment case 1. The shirt top plate 31 opens and closes via a cam plate 33 and an arm 34 when a motor 32 rotates once based on a discharge command signal or the like, and discharges the pouch. Note that when the motor 32 rotates once, the micro switch 3

FIG. 3 is a block diagram showing the control state of the above-mentioned pouch inserting machine.

In the figure, reference numeral 40 denotes a power supply unit, and this power supply unit 4o is supplied with a power supply voltage from an external power supply, and is connected to each of the first to fifth control circuits 41.
42, 43, 44, and 45, respectively. The first control circuit 41 receives the detection signal A from the second detector 8 that detects the amount of pouches in the small quantity supply trough 5, and based on this, the vibrator 11 of the supply staff collar 4 is inputted.
A control signal B is outputted to control the vibration of the feed hopper 4, thereby controlling the feed amount of the supply hopper 4. That is, when there are only a few bags in the small quantity supply trough 5, the first control circuit 41 increases the vibration of the vibrator 11 in response to the detection signal A from the second detector 8, and reduces the feed of the supply hopper 4. Increase the amount. Conversely, when there are many small bags in the small quantity supply trough 5, the first control circuit 41 reduces the vibration of the vibrator 11 in response to the detection signal A, reduces the feed rate of the supply hopper 4, and
Depending on the situation, feeding of the supply hopper 4 may be stopped. Similarly, the second control circuit 42 receives the detection signal C from the third detector 9 that detects the amount of sachets on the receiving portion 6a of the delivery trough 6, and based on this, the second control circuit 42 controls the small amount supply trough 5. By outputting a control signal that controls the vibration of the vibrator 13 and controlling the feed amount of the small amount supply trough 5, the delivery trough 6
The amount of sachets is regulated to a certain amount. A third control circuit 43 detects a detection signal from a fourth detector 10 that detects the amount of pouches on the alignment section 6b of the delivery trough 6, and a fifth control circuit that detects whether or not there is a pouch on the receiving section 16. The detection signal F from the detector 19 of
A control signal G for controlling the vibration of the pipe rake 14 of No. 6 is output, and the feed amount of the delivery trough 6 is controlled. The fourth control circuit 44 receives the detection signal r from the detector 19 of the receiver 16 described above and the discharge signal from the fifth control circuit 45 described later, and inputs these signals F and I. Based on this, a drive signal J is output to the motor 23 of the suction device 17.

This drive signal J drives the motor 23 to attract and pull up the pouch in the receiving section 16 with the suction tube 21, and send the pouch detached by the detachment plate 24 to the chute section 18. Further, the fifth control circuit 45 inputs a detection signal from the sixth detector 20 that detects the pouch being fed into the chute section 18 and a discharge signal from the control section 46, which will be described later.
In addition to outputting an ejection signal to the fourth control circuit 44 described above based on each of these signals, and outputting a detection signal M to the control section 46, an ejection completion signal N and an ejection error signal P are also output. Output. The detection signal M is detected by the sixth detector 20
It is output in response to a detection signal K from. The ejection completion signal N is output when the pouch is reliably ejected from the chute section 18. The discharge error signal P is sent to the chute section 18.
Output when the pouch is not ejected from the . This is output when the shirt cover plate 31 is opened when there is no pouch in the chute section 18. The control unit 46 also receives a detection signal M from the sixth control circuit 45 and a discharge command signal R, which will be described later, and outputs a drive signal Q to the motor 32 of the chute unit 18 based on this. 6 control circuit 4
Outputs the discharge signal to 5. For example, when the pouch dispensing machine is used in conjunction with a food packaging machine, the discharge error signal is given by the packaging machine, or when the pouch dispensing machine is used alone, it is given by a push button switch or foot pedal switch. It is given from etc. The drive signal Q drives the motor 32 to open and close the shirt plate 31 of the chute section 18 and discharge the pouch.

Note that the first detector 7 that detects the amount of sachets in the supply hopper 4 outputs a detection signal S to the controller 47.

This controller 47 uses the alarm 48 based on the detection signal S.
It outputs an alarm signal T to a packet conveyor, and also outputs an external output signal U to a packet conveyor or the like.

Next, the operation of the pouch inserting machine configured as described above will be explained.

First, a large amount of small bags are put into the supply hopper 4.

Then, the small bag is sent from the supply hopper 4 to the small quantity supply trough 5 via the guide chute 12 in response to the vibration of the vibrator 11. At this time, the amount of sachets on the small amount supply trough 5 is detected by the second detector 8, and the detection signal A is input to the first control circuit 41. Based on this, the control circuit 4
1 controls the vibration of the pipe rake 11 of the supply hopper 4, so that the amount of pouches sent out from the supply hopper 4 is controlled.

That is, when the amount of sachets on the small amount supply trough 5 is small, a large amount is sent out, and as the amount gradually increases, the amount sent out decreases, and when a certain amount is reached, the supply hopper 4 stops. The pouches are fed from the small supply trough 5 to the delivery trough 76 in response to the vibrations of the vibrator 13. At this time, the third detector 9 detects the amount of pouches sent into the receiving part 6a of the delivery trough 6, and this detection signal C is input to the second control circuit 42, and the control circuit 42 is activated based on this. Since the vibration of the vibrator 13 of the small quantity supply trough 5 is controlled, the amount of pouches delivered from the small quantity supply trough 5 is controlled. In this way,
When the small bags sent into the receiving part 6a of the delivery trough 6 are sent from the receiving part 6a to the alignment part 6b in response to the vibration of the vibrator 14, the small bags are kept in the alignment part by a regulating part (not shown) of the receiving part 6a. 6b so that they are lined up in a line, and after being aligned in a line at the alignment part 6b, they are sent into the receiving part 16 one after another.

In this case, the spacing between the pouches aligned in the alignment section 6b is detected by the fourth detector 10, and this detection signal l is input to the third control circuit 43, and based on this, the control circuit 4
3 controls the vibration of the vibrator 14, so the alignment section 6
The spacing between the pouches on b is always constant. In addition, the alignment section 6b
The small bag fed into the receiving part 16 is sent to the fifth detector 19.
It is detected whether or not the vibrator is in the receiving part 16, and this detection signal F is input to the third control circuit 43, and the control circuit 43 also controls the vibration of the vibrator 14 by this.
The alignment section 6b controls feeding of the pouches to the receiving section 16.

In this way, when the drive signal J output from the fourth control circuit 44 is input to the motor 23 of the suction device 17, the suction tube 21 is operated, and the pouch sent into the receiving part 16 is The pieces are fed into the chute section 8 one by one. That is, the fourth
The control circuit 44 receives the detection signal F from the fifth detector 19 that detects whether there is a pouch in the receiving part 16 and the discharge signal from the fifth control circuit 45. , outputs a drive signal J. Then, the motor 23 of the suction device 17 is rotated by the drive signal J, and the cam plate 26 and the arm 2 are rotated.
7, the suction tube 21 reciprocates along a guide rod (not shown). As a result, since the suction tube 21 is connected to the vacuum pump 22 by the vinyl hose 25, when it is pushed out, it attracts one pouch that is received by the receiving part 16, and when it is pulled in, it pulls up the pouch. , forcibly by the detachment plate 24 (against the suction force of the suction tube 21)
Then, the pouch is removed and sent into the chute section 18.

In this case, even if there are two or more pouches in the receiving part 16, the suction tube 21 not only suctions only one pouch, but also when it comes into contact with the uppermost pouch, the coil spring 28 causes the suction tube to 21 extrusions can be absorbed to prevent damage to the sachet and its contents. Further, the motor 23 is automatically stopped by the microswitch 29 after one revolution.

Furthermore, the pouch sent out from the receiving part 16 by the suction device 17 is detected by the sixth detector 20 as it passes through the chute part 18 or not.

The pouch sent into the chute section 18 is temporarily stored by the shirt plate 31, and the discharge command signal R is input to the control section 46, and the detection signal K from the sixth detector 20 is sent to the fifth control circuit. When the detection signal M is inputted to the control unit 46 via the signal line 45, the shirt cover plate 31 opens,
It is discharged from the chute section 18. That is, when the discharge command signal R and the detection signal are input, the control section 46 outputs the drive signal Q.
is output to the motor 32. As a result, the motor 32 rotates, and the shutter plate 31 opens and closes via the cam plate 33 and the arm 34. In this case as well, the motor 32 is automatically stopped by the microphone switch 35 after one rotation.

In this way, the small bags are sequentially discharged from the chute section 18 one by one, and when the number of small bags in the supply hopper 4 decreases, a detection signal S is output from the first detector 7 to the controller 47.
Based on this, an alarm signal T is sent from the controller 47 to the alarm 48.
At the same time, an external output signal U is outputted to a packet conveyor or the like, and as a result, a large number of small bags are fed into the supply hopper 4 again.

However, according to the above-mentioned sachet insertion machine, does it require any manual labor? , it is possible to reliably and quickly send out individual sachets one by one without damaging the individual sachets. Incidentally, the pouch feeder has the ability to feed out approximately 50 to 60 pouches one by one per minute.

In the above-described embodiment, the delivery truck 76 that sequentially sends out the pouches in response to the vibrations of the vibrator 14 is provided with the alignment section 6b that arranges the pouches in a line, but the present invention is not limited to this and is not necessarily limited to this. There is no need to line up the pouches, and any method may be used as long as the pouches are simply fed into the receiver s16.

Further, in the embodiment described above, the suction pipe 21 is connected to the vacuum pump 22.
Although the air is sucked in by connecting the suction tube 21 to the compressor through an adapter, the present invention is not limited to this, and air may be sucked in by connecting the suction pipe 21 to the compressor via an adapter, for example.

〔Effect of the invention〕

As explained above, according to the pouch dispensing machine according to the present invention, the delivery trough sequentially sends out the pouches in response to the vibration of the vibrator, receives the delivered pouches at the receiving part, and absorbs the received pouches. σ (Because the device sends out one bag at a time, it has the excellent advantage of not requiring any manpower, without damaging the separate sachets, and being able to send out one bag at a time reliably and quickly.) .
