Abstract

PURPOSE:To eliminate any empty bag by supplementing a product to an empty attachment part when the empty attachment part is generated caused by mis- supply in a packing device for packing small articles like candies, gums, chocolates, crakers, cookies and fishing weights. CONSTITUTION:The presence or absence of an article to be packed is detected on an attachment 31 of a chain conveyor 3 by a photoelectric sensor 61 provided on a conveying process B, and the signal is input into a computer 6. Only when the article to be packed is not placed on the attachment 31, a product supplement device 2 is operated by the output from the computer. The article to be packed, in a through hole 26 of a slide board 22 positioned in the lower end of a magazine 21 in which the article to be packed is previously contained is dropped on the attachment 31 from an input port provided just above the attachment 31 by its own weight by the transfer of the slide board 22 connected to a drive device. Therefore, the articles to be packed are loaded on the whole of the attachments 31 to be moved to the packing process, so that the generation of the empty bag can be eliminated.

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is an apparatus for packaging small items such as candy, gum, biscuits, chocolates, and weights for fishing, which can eliminate mistakes in supply of packaged items to the packaging process. The present invention relates to a product replenishing device for a bucket with insufficient quantity supplied to a packaging machine.

2. Description of the Related Art Conventionally, a syrup-like bag-like product such as a candy contains a plurality of individually-packaged candy in the bag. For this individual wrapping, in the horizontal pillow wrapping machine which is a series of three processes including supply process, transfer process, wrapping process,
First, a large number of items to be packaged, candy, are manually supplied onto the supply disc. As shown in FIG. 4 (a), the candy 5 is inserted into a large number of holes 11 provided on the outer periphery of the disk 1 while rotating the disk 1, and the shoot 12 is ejected from the hole 11 at a predetermined position by its own weight. It slides up, is placed on the attachment 31 part of the chain conveyor 3 which is a carrying process, and is carried to the packaging process by the chain drive as it is, and then individually packaged.

A large number of holes 11 provided in the disk 1
And the attach 31 part of the chain conveyor 3 are synchronized, and the candy 5 inserted into the hole 11 is continuously and sequentially supplied to the attach 31 part of the chain conveyor 3 which is continuously operating. However, if the candy 5 is not inserted into the hole 11 while the disk 1 rotates once, the hole 11
The candy 5 is not sent to the attach 31 part of the chain conveyor 3 synchronized with the above, and the attach 31 part of the chain conveyor 3 moves to the packaging step in a state where the candy 5 is not placed. Also, in the packaging process, the wrapping paper is continuously fed out, and even if the chain conveyor with no candy is attached, the wrapping paper is fed out as it is, and thus the three-sided seal and cutting are performed without the candy. , Empty bags will be sent to the next process.

Furthermore, in order to pack a plurality of individually packaged candy as described above into a bag and to commercialize the candy, it is necessary to remove the empty bag. As a means for removing the empty bag, a bag containing a candy is used. A device that sucks up and removes a light empty bag with a vacuum by using the difference in weight from a bag that does not contain a bag, and a wind separator that drops individual packages and blows air in the middle to blow away the empty bag. Only the empty bag was removed from the group of individual packages. Then, only the individual packaged product containing the candy was weighed by a target weight, and the measured individual packaged product was bag-packed in a packaging machine to be commercialized.

[0005]

However, although the above-described vacuum device and wind-powered separating machine are used as a method for removing this empty bag, generally, in the production of candy and the like, the number of revolutions of the packaging machine is one. Since it was a very high speed of about 500 revolutions per minute, the vacuum device could not keep up with the processing capacity of the individual packaged product and the empty bag could not be completely removed.
Also, in wind-powered delivery machines, it is often the case that empty bags are sandwiched between candy-containing individually packaged products, and it is difficult to blow empty bags in this state. It had gone inside. Furthermore, since these devices are selected by wind pressure and suction force, it is extremely difficult to adjust, especially for lightweight ones, so empty bags may be included in bagged products, leading to consumer complaints. It was Therefore, removing the empty bag has been an important issue in production.

The present invention has been made in view of the above-mentioned problems, and in a continuous packaging machine, by replenishing empty buckets and insufficient quantity buckets with products, individual packaged goods with insufficient quantity It is also an object of the present invention to provide a product replenishing device for a shortage-of-measuring bucket that supplies a packaging machine capable of eliminating the occurrence of empty bags.

[0007]

SUMMARY OF THE INVENTION The above-mentioned object is an apparatus for replenishing a bucket conveyor for supplying a product in units of the packaging machine pitch of a packaging machine with a product which is insufficient in quantity. A product detector for detecting the presence or absence of the product, a product replenishment device provided downstream of the product detector for supplying the same product prepared in advance to the bucket by the quantity shortage, and the product quantity of the product detector. After counting the synchronization signal according to the interval between the product detector and the product replenishing device by the shortage detection signal and the synchronization signal generated for each packaging pitch of the packaging machine, the product replenishing device is driven to replenish the bucket with the required amount of product. It is achieved by a product replenishing device for the insufficient quantity bucket to supply to the packaging machine.

[0008]

In the product replenishing device according to the present invention, in the continuous packaging machine, the article to be packaged on the supply disc is not inserted into the hole on the outer peripheral portion of the supply disc and is not supplied to the attaching part on the chain conveyor. In this case, the detection means for determining the presence or absence of the article to be packaged inputs a signal to the computer that the article to be packaged does not exist in the attached portion, and the computer sends an output to the solenoid valve for operating the product replenishing device.
Then, the slide plate having the through hole of the product replenishing device accommodates one article to be packaged dropped from the magazine in which several articles to be packaged are loaded and accommodated in the through hole, and is directly above the attaching portion on the chain conveyor. The slide plate is moved to the insertion port of the slide stand provided in the above, and both holes are aligned so that they communicate with each other. Drop it by its own weight into the attachment part. Then, the slide plate returns to the original position.

Therefore, in the process in which the articles to be packaged are sequentially supplied from the supply disc to the attach section on the chain conveyor, even if the article to be packaged is not supplied to the attach section for some reason, the product is replenished. The device can be operated to supply the object to be packaged to the attach portion on the chain conveyor where the object to be packaged is not placed, and all the object to be packaged is attached to the attach part after the product replenishing device. Therefore, the mistake of supplying the packaged product to the packaging process is eliminated, and the empty bag is never generated, so that the empty bag does not enter the bagged product.

[0010]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a schematic configuration diagram of a packaging line incorporating a product replenishing device 2 according to the present invention. This product replenishing device 2
Is a supply step A for supplying the candy 5 as the object to be packaged to the attach 31 part on the chain conveyor 3 by the supply disc 1.
And the candy 5 at an interval synchronized with the packaging pitch of the subsequent packaging machine.
Is provided in the conveying step B in a packaging line including a conveying step B for continuously supplying the candy 5 on the attachment 31 part on the endless chain conveyor 3 and a packaging step C for packaging the supplied candy 5. In the supplying step A, if the candy 5 cannot be supplied to the attach 31 part for some reason, the candy 5 is replenished to the empty attach 31 part. That is, the product replenishing device 2 includes a photoelectric sensor 61, which is provided on the carrying process B, for determining whether or not the candy 5 is loaded on the attach 31 part, and the computer 6.
, A solenoid valve 64, and the product replenishing device 2 operated by the solenoid valve 64.

The computer 6 is a photoelectric sensor 6
When the signal indicating that there is no candy 5 is received from 1, the product replenishing device 2 provided on the downstream side of the photoelectric sensor 61 is operated and the candy 5 is replenished to the empty attachment 31 part. The logic is such that after counting the synchronization signal 63 from the packaging machine for the packaging pitch from the input to the product replenishing device 2, the signal is output to the solenoid valve 64.

2 and 3, the product replenishing device 2 is shown.
2 shows an external view 2 and a partially cutaway side view 3. In these figures, reference numeral 4 is a carrier that serves as a guide for the attach 31 part on the chain conveyor 3 when the candy 5 is transported. Reference numeral 23 denotes a slide mount of the product replenishing device 2, which is a long body having a slide plate 22 attached to a sliding portion, and is horizontally mounted on the attach conveyor 3 and the carrier 21. A candy 5 is placed on the slide base 23 and the slide plate 22.
There is one square hole that can hold one.
The candy 5 is a guide hole 2 which is an insertion port of the slide mount 23.
After passing through 7, the candy 5 is dropped into the attached portion 31 where the candy 5 is not placed. Reference numeral 28 denotes a slide cover, which is provided to cover the upper surface of a slide plate 22 described later so that the slide plate 22 can slide smoothly. Reference numeral 21 is a magazine that can accommodate several candy 5 in a stacked state, and is attached to a slide base 23 so that a slide plate 22 can freely move in and out below the magazine 21. Reference numeral 22 denotes the above-mentioned slide plate, which is composed of a through hole 26 that can accommodate one candy 5 at its tip and an elongated body having that thickness. The telescopic rod 25 of the air cylinder 24 for reciprocating the slide mount 23 is fixedly connected to the rear end of the slide plate 22. The present invention is configured as described above.

Next, the operation will be described. When the candy 5 is mistakenly supplied in the supplying step A and the candy 5 is conveyed to the packaging step C without being loaded in the attach 31 part, the photoelectric sensor 61 provided during the conveyance detects the absence of the candy. 62 is input to the computer 6, and an output is sent from the computer 6 to the solenoid valve 64 to operate the product replenishing device 2. That is, by driving the air cylinder 24 connected to the slide plate 22, the through hole 26 of the slide plate 22 located at the lower end of the magazine 21 in which the candy 5 is previously stored is stored in the magazine 21. The candy 5 at the lowermost end is accommodated in the through hole 26 and moved to the left in the drawing, and the through hole 26 of the slide plate 22 is slid to a position coinciding with the guide hole 27 of the slide base 23. Then, when the holes 26 and 27 coincide with each other, the candy 5 housed in the through hole 26 passes through the guide hole 27 and is dropped onto the attach 31 by its own weight. In this case, since the candy 5 is housed in the through hole 26 even when the slide plate 22 is operated at high speed, the candy 5 does not jump out of the slide plate during the slide, and the candy 5 is driven by the air cylinder 24 when driven. Even if the kinetic energy is applied, the energy is horizontal, so that the energy disappears by colliding with the inner wall of the through hole 26, and the weight drop quickly without becoming unstable. Although the embodiment describes the attachment as a product to be individually conveyed, the present invention is not limited to this, and a bucket conveyor, a flanged conveyor, or the like may be used. Further, when the processing capacity of the packaging machine is high, a plurality of product replenishing devices may be provided side by side and alternately controlled.

[0014]

As described in detail above, according to the present invention, since all the candy is loaded on the attachment of the chain conveyor which conveys to the packaging machine, empty bags are not generated in the packaging machine. Therefore, empty bags were not mixed in the packaged product, and there were no consumer complaints.
