Abstract

PURPOSE:To make removal correct and improve working efficiency by sensing inappropriate chopsticks which are not placed in a predetermined direction on a transfer path and blowing them to a side by pressed air for removing. CONSTITUTION:An endless rubber belt with recessed grooves having a depth with disposable wooden chopsticks 2 slightly protruding arranged in parallel is hung between side plates 44 to form a transfer path 3. The rubber belt is equipped with a pressing plate 39 in contact with a surface of the chopsticks 2 which flaps with a pivotal shaft 40 as the center. In addition a protruding part 42 is fold-formed from a lower end of the plate 39 to the shaft 40 side, wherein a degree of the protrusion is set such that a rear face is not in contact with the surface of the chopsticks 2. Therefore, if inappropriate chopsticks are sensed by a sensor 5 of an inappropriate chopstick removing mechanism 6, the rubber belt stops when the inappropriate chopsticks stop at the protruding part 42 position, and pressed air is ejected from an air ejection tube 43 to an end face of the chopsticks so that the chopsticks are discharged from the recessed groove through a window hole 45 formed on the side plate 44 into a chute 46 to be removed. Thus inappropriate chopsticks can be easily and reliably removed.

If one is vertically inserted in the groove 32, the flexible piece 55
Is turned up and touches the sensor G, detects an abnormality, and the apparatus stops.

On the front side of the main body 7 of the endless rubber belt 33, a standby portion 52 is provided so as to be continuous with the endless rubber belt 33, and two guide rods 47 of two constitutions are provided on the left and right sides of the standby portion 52. The disposable chopsticks 2 that have been conveyed to the front side of the main body 7 by the endless rubber belt 33 are introduced into the standby portion 52, and the guide rod having a double structure.
An extended portion 53 which is inserted between 47 and extended on both sides by the guide rod 47 and on the separation prevention plate 54 and hung down.
It is guided in the center by and is made to fall to the lower end of the standby part 52, and the receiving plate 48 having a substantially V-shaped cross section provided at the lower end of the standby part 52.
The chopsticks 2 sequentially received by the endless rubber belt 33 are received by the receiving plate 48.
They will be stacked one by one on standby. At this time, since the tapered side of the disposable chopsticks 2 is located on the right side in FIG. 1, the laminated disposable chopsticks 2 are generally inclined from the left side to the right side in FIG.

On the outside of the receiving plate 48, the roller 15 described above is provided.
As a result, the wrapping paper 4 bent into a V-shaped cross section is continuously passing.

On the front side (the left side in FIG. 4) of the receiving plate 48, a locking portion 49 'is formed at the tip for delivering only the lowermost chopstick 2 on the receiving plate 48 to the left in FIG. A chopstick feeding section 50 having a feeding body 49 is provided.

The chopstick feeding section 50 is an endless transport mechanism in which the endless chain 51 is configured to rotate on a horizontal plane. The delivery body 49 is pivotally attached at a predetermined interval to the endless chain 51 at a predetermined interval, and when the endless chain 51 is rotated by an appropriate drive source, the delivery body 49 also tilts in a direction opposite to the rotation direction on a horizontal plane. In this state, the locking member 49 'of the feeding body 49 locks the tapered end surface of the disposable chopstick 2 on the lowermost stage stacked on the receiving plate 48, and feeds it forward. When pulled out from the receiving plate 48, the disposable chopsticks 2 are introduced from the base end side of the thick width onto the wrapping paper 4 which is continuously conveyed on the outer side (lower side) of the receiving plate 48. The disposable chopsticks 2 at the bottom of which the sending bodies 49 are laminated one after another
By engaging and transporting the chopsticks 2, the disposable chopsticks 2 are successively introduced onto the wrapping paper 4.

A projection is formed on the outlet side end of the receiving plate 48 so that the wrapping paper 4 and the receiving plate 48 do not contact each other on the entire surface. When the device is stopped, the glue attached to the wrapping paper 4 is attached to the outer surface of the receiving plate 48, and the wrapping paper 4 is prevented from being cut when the device is operated again. is there.

The standby portion 52 is structured so as to be swingable back and forth by an eccentric mechanism in order to arrange the plurality of split chopsticks 2 which are waiting to be stacked in order and drop them well downward. Some of the disposable chopsticks 2 are slightly warped and others are slightly curved, so that the disposable chopsticks 2 are carefully dropped so as not to be dropped downward.

Further, as shown in FIG. 13, the standby section 52 is provided with reflection type sensors H and I (photoelectric tube type sensor in which the cathode and the anode are provided on the same side). When the disposable chopsticks 2 placed in the stack on 52 are above the position of the sensor H on the upper side, the endless rubber belt 33
Is stopped, and the endless rubber belt 33 is started to be conveyed when the position is below the position of the lower sensor I. Inappropriate chopsticks are removed from the endless rubber belt 33, and the endless rubber belt is removed from the hopper 1.
The disposable chopsticks 2 may not be fitted properly on the 33, and the concave groove 32 in which the disposable chopsticks 2 may not be fitted may continuously appear. In consideration of these points, the sensors H and I are provided in conjunction with the drive source 56 of the endless rubber belt 33 so that an appropriate amount of the disposable chopsticks 2 can be stacked and waited at all times.

Regarding the post-processing section 71 (see FIG. 2).

When the disposable chopsticks 2 are introduced one by one into the wrapping paper 4 continuously conveyed in the disposable chopsticks feeding / introducing section 31, the edges of the wrapping paper 4 glued by the gluing section 14 are sealed by the sealing section 72. Then, one set of chopsticks 2 is obtained, which is sealed by, and subsequently cut by the cutter portion 73 to a predetermined length and wrapped with the wrapping paper 4 as shown in FIG. S in FIG. 14 is a sealed portion.

A conveyor device 74 is installed side by side on one side of the cutter section 73. In this conveyor device 74, two endless belts 75, which are opposed to each other with a space between both ends of the packed chopsticks 2, are rotatably arranged, and a stopper 76 is provided between the endless belts 75. It is installed so that it can be sunk freely. Assuming that the sensor has a preset number, for example, 20, the stopper 76 is immersed until the number of packed chopsticks 2 is counted by 20, and when the number of sets is 20, the stopper 76 protrudes for a predetermined period of time and then retracts. Therefore, the disposable chopsticks 2 packed on the endless belt 75 are conveyed as a group of 20 sets. Therefore, if the packed chopsticks 2 on the endless belt 75 form a group of 20 sets, for example, if it is configured to produce a sound, an operator can pick up the group by hand and put the group of 20 sets in a plastic bag. Packed disposable chopsticks 2 can be packed.

Incidentally, the conveyor device 74 should have two disposable chopsticks.
When there is a wrapping paper 4 that does not contain, a blower unit is provided to blow off the empty wrapping paper 4.

Regarding the disposable chopsticks inserting section 91 (see FIG. 2).

An endless belt 92, which is intermittently conveyed, is provided on the left side in FIG. A guide plate 94 is erected on the left side of the endless belt 92 in FIG. 2, and a section plate 93 on which the inner surface and the end surface of the guide plate 94 contact and slide at a predetermined interval. The endless belt 92 is installed upright.
At the end (upper side in FIG. 2) of the
A slide body 96 that slides while being guided by 95 is provided.
At the end position of the sliding body 96 (on the right side in FIG. 2), the disposable chopsticks 2 on the sliding body 96 are dropped from the upper side to the lower side in FIG. A chopstick pusher 97 is provided. Reference numeral 101 is a cylinder device of the chopstick pusher 97.

Therefore, the chopsticks 2 with a plurality of sets placed on the endless belt 92 between the section plates 94 are conveyed to the end by the endless belt 92, and are introduced onto the slide body 96 which stands by at this position. Then, the sliding body 96 conveys the disposable chopsticks 2 to the end position, and then the chopstick pusher 97 projects to slide the sliding body.
The disposable chopsticks 2 on 96 are dropped into the hopper 1.

The hopper portion 1 is provided with a closing plate 98, and a window hole 99 is formed in the closing plate 98 so that the blade 37 of the blade body 38 hangs downward from the window hole 99. Has been done. This is because when the disposable chopsticks 2 are scraped off by the blades 37 of the blade body 38, the disposable chopsticks 2 are tapered and the disposable chopsticks 2 and the tip edges of the blades 37 are not parallel, and the disposable chopsticks 2 rise up and become vertical. However, the presence of the closing plate 98 prevents the disposable chopsticks 2 from standing up, and the closing plate 98 prevents the disposable chopsticks 2 from rising up.

Further, a concave curved surface 1 is provided on the bottom of the hopper 1.
The chopstick 2 formed in No. 02 has a pool 100 formed therein. Therefore, the concave curved surface 102 has a curved groove shape extending in the width direction of the endless rubber belt 33. Therefore,
The disposable chopsticks 2 accumulated in the pool 100 are the concave curved surfaces 1
In the vicinity of 02, the rubber is naturally fitted into the concave groove 32 of the endless rubber belt 33 which moves upward. Since the disposable chopsticks 2 are not forcibly fitted into the concave grooves 32 but are naturally fitted therein, the disposable chopsticks 2 are not cracked and fitted into the concave grooves 32. In particular, since the concave curved surface 102 is present, the split chopsticks 2 are significantly less likely to break. For example, when the bottom is not a concave curved surface 102 but a bent V-shaped groove, the load of the disposable chopsticks 2 on the upper part of the basin 100 is lower than the disposable chopsticks 2 on the lower part.
May be caught in the V-shaped groove and the split chopsticks 2 may be broken, but this does not occur in the case of the present embodiment.

The hopper unit 1 is provided with a sensor J, and the amount of the disposable chopsticks 2 carried by the endless belt 92 and the sliding body 96 is controlled by the remaining amount of the disposable chopsticks 2 in the hopper unit 1. There is.

Since this embodiment has the above-mentioned structure, the following operational effects are exhibited.

First, a predetermined number of disposable chopsticks 2 placed on the endless belt 92 between the section plates 93 are sequentially conveyed by the endless belt 92 and transferred onto the sliding body 96 which is waiting to stop at the end position. . The sliding body 96 slides to a position above the hopper unit 1, and the chopstick pusher 97 projects to drop the disposable chopsticks 2 on the sliding body 96 into the hopper unit 1. Empty sliding body
96 slides back, and similarly receives the disposable chopsticks 2 on the endless belt 92.

Since the conveying path 3 moving upward is disposed near the concave curved surface 102 at the bottom of the hopper section 1,
The disposable chopsticks 2 in the hopper 1 are sequentially inserted into the concave grooves 32 of the conveying path 3 and conveyed. The insertion direction of the disposable chopsticks 2 in the groove 32 is set so that the tapered side is located on the left side in FIG.

When the disposable chopsticks 2 are not properly fitted in the concave grooves 32, the disposable chopsticks 2 are scraped off by the blades 37 of the blade body 38 provided above the pool 100.

Even if there is a disposable chopstick 2 which is not scraped off by the operation of the blade 38 and is not properly fitted in the concave groove 32, the disposable chopstick 2 fitted in the rear surface of the pressing plate 39 and the concave groove 32 is present. Since there is a slight clearance from the surface of the disposable chopsticks 2, the disposable chopsticks 2 which were not properly fitted in the recessed grooves 32 are slidably fitted into the recessed grooves 32 by sliding on the back surface of the pressing plate 39.

Although the chopsticks are properly fitted in the groove 32, the improper chopsticks are detected by the sensor shown in FIGS. 6, 7, 8 and 9, and the endless rubber belt 33 is placed at a predetermined position.
When the air 33 is stopped, pressurized air is jetted from the air jet pipe 43 and removed to the side of the endless rubber belt 33.

For example, a means for injecting pressurized air from below the endless rubber belt 33 and removing the unsuitable chopsticks to the upper part of the endless rubber belt 33 makes it difficult to collect the removed unsuitable chopsticks. In this respect, in this embodiment, since the endless rubber belt 33 having a predetermined width is removed laterally, the inappropriate chopsticks can be removed very efficiently.

While the endless rubber belt 33 conveys the split chopsticks 2 to the front side of the main body 7, the split chopsticks 2 are held by the detachment prevention plate 54, and one set of chopsticks and one set of chopsticks are placed in one groove 32. If it is inserted, it is detected by the flexible piece 55 and the sensor.

At the end position of the endless rubber belt 33, the split chopsticks 2 are guided by the guide rod 47 and the extended portion 53 of the separation prevention plate 54 and dropped onto the receiving plate 48 at the lower end of the standby portion 52.
Since the standby portion 52 is configured to be swingable by the eccentric mechanism, the disposable chopsticks 2 are properly dropped.

Of the disposable chopsticks 2 stacked on the receiving plate 48, the lowermost disposable chopstick 2 is locked by the sending-out body 49 of the rotating chopstick sending-out unit 50 and slides on the receiving plate 48 to receive it. It is introduced onto the wrapping paper 4 that is continuously conveyed below the plate 48.

In the wrapping paper processing unit 11, this wrapping paper 4 is
Printing and gluing have been completed.

When the disposable chopsticks 2 are introduced onto the wrapping paper 4 one by one, the disposable chopsticks 2 are sealed by the seal portion 72 and cut into a predetermined length by the cutter portion 73 to obtain the packaged disposable chopsticks 2.

The packed disposable chopsticks 2 are sequentially provided with a conveyor device.
Transported on 74. On the conveyor device 74, the stoppers 76 are projected and retracted so that a predetermined number of them are collected and conveyed on the conveyor device 74.

[0069]

Since the present invention is configured as described above, it is possible to automatically detect and remove inappropriate chopsticks existing in the transport path, instead of visually checking and removing the inappropriate chopsticks. Since the structure is not blown away by mechanical means but blown off by air, it is possible to easily and reliably remove the incorrect chopsticks. Since the chopsticks are blown away by the air from one side, the improper chopsticks can be efficiently led out of the conveyance path, and thus the excellent chopstick chopstick packaging device can prevent the improper chopstick chopsticks from being packaged.
