DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing and packaging apparatus for continuously measuring and packaging goods carried in, and further calculating a price and the like based on weighing data.

[0002]

2. Description of the Related Art In a weighing / packaging / pricing apparatus, the packaging of one product is completed in a plurality of packaging cycles (usually two packaging cycles) in order to improve the processing efficiency of the apparatus.
For example, in the case of two packaging cycles, the first half of one cycle pushes up the product by the elevator and the left and right folding plates,
The end of the film is folded into the bottom of the product by the front folding plate, and the film is pulled out and centered in the latter half of one cycle. Then, in parallel with these operations, the goods are conveyed onto the elevator head. Looking at this one product, in the first packaging cycle, the product is loaded onto the elevator head, the film is drawn out, and the centering of the film of a predetermined length is performed, and the second packaging cycle is performed. Then, the product is pushed up by the elevator, the end of the film is folded into the bottom of the product, and the product after packaging is carried out.

[0003]

Conventionally, in this type of apparatus, a product is placed on a weighing dish which also serves as a product placement table provided at the carry-in end, and when the weighing is stabilized, the packaging machine is activated. It is configured to perform the operation of one packaging cycle. For this reason, since the last product is not placed on the weighing pan, the last product remains loaded on the elevator head unless some means is taken.

Therefore, conventionally, in the case of the last product, the operating means is operated to input the fact. However, this method is troublesome because the operating means must be operated, and if you forget to operate it, the last product will not be carried out forever and will remain on the elevator head for a long time. (In this case, the film is also left in a centered state).

[0005] The present invention has been made in view of the above-mentioned problems of the prior art.
It is an object of the present invention to provide a weighing / packaging / pricing device that can pack the last product without any special operation by an operator.

[0006]

In order to achieve the above object, the technical measures taken by the present invention are as follows. At the end of the packaging cycle, the weighing of the next product is stable (first
), The operation of the next packaging cycle is started to perform the normal operation, and the next product is placed on the weighing pan but the weighing is not stable (second case). When the weighing is stabilized, the operation of the next packaging cycle is started to perform the normal operation, and when there is no product placed on the weighing pan and the product is present inside the device (No. 3), the operation of the next packaging cycle is started to package the product inside the apparatus. The determination as to which of the above-described first to third states corresponds to whether the product is placed on the weighing pan, that is, whether the weighing value is “0”, When a product is placed, it is determined whether the weighing value is stable. When the weighing value is not stable, the next operation is performed after the weighing value is stabilized. The weighing / packaging and pricing device includes a loading mechanism for moving a product on a weighing dish along a transport path and transporting the product into the inside of the device, a film transport mechanism for pulling out a film of a predetermined length from a film roll to a packaging unit, and a loading mechanism. The product carried into the apparatus is pushed up to the film stretched over the packaging part by an elevator mechanism for covering the upper surface of the product with the film, the folding mechanism for folding the film end to the bottom of the product, and the product being carried out from the packaging part. It is characterized by having an unloading mechanism. In the third case, the loading mechanism and the film transport mechanism are not activated.

[0007] A plurality of packaging cycles for packaging the above-mentioned one product include a form completed in two packaging cycles and a form completed in three packaging cycles. In the case of the form completed in two packaging cycles, the loading of the product by the loading mechanism and the stretching of the film to the packaging part by the film transport mechanism are performed in the first packaging cycle, and in the second packaging cycle, The product is pushed up by the elevator mechanism, the end of the film is folded into the bottom of the product by the folding mechanism, and the packaged product is carried out by the carry-out mechanism. In the case of the form completed in three packaging cycles, the goods are carried into a predetermined position on the carrying path by the carrying mechanism in the first packaging cycle,
In the second packaging cycle, the goods are loaded onto the elevator by the loading mechanism, and the film is stretched on the packaging part by the film transport mechanism. In the third packaging cycle, the goods are pushed up and folded by the elevator mechanism. The film end is folded into the bottom of the product by the mechanism, and the packaged product is carried out by the carry-out mechanism. Further, as a form to be completed in three packaging cycles, in the first packaging cycle, the loading of the product by the loading mechanism and stretching of the film to the packaging part by the film transport means are performed, and the second packaging cycle is performed. The product is pushed up by the elevator mechanism, the end of the film is folded into the bottom of the product by the folding mechanism, and the packaged product is unloaded by the unloading mechanism. The label is affixed to the packaged product in the third packaging cycle. In some cases, it is performed.

Further, a price or the like is calculated based on the weighing of the product, and the label printed with the data is attached to the product automatically during or after the product is carried out, or It may be performed manually after unloading. With the above configuration, in the first and second cases, the packaging of one product is continuously performed in a plurality of packaging cycles, as in the related art. In the third case, that is, when the packaging cycle is completed (the operation of the packaging machine is completed), when there is no product on the weighing pan, and when the product is present inside the apparatus, the packaging is performed. The case in which the product inside the machine is the last product, and the case where the next product is not placed before the current packaging cycle is completed due to the work or the operator's convenience, which is not the last product. Therefore, in the case of the last product, the packaging process of the last product is executed without any special operation by the operator. If the product is not the last product, the next product is placed after or after the packaging process of the last product is completed. Then, the operation of the packaging machine is started. If a product is placed during the packaging process of the last product, the first or second case is reached, and the next packaging cycle is continued after the end of the packaging cycle.

Next, the outline of the packaging operation of the above-described apparatus will be briefly described. In the illustrated apparatus, as shown in FIG. 5, the product is configured so that the packaging is completed in two consecutive machine cycles. The machine cycle is a period from when the packaging machine is started to when a series of packaging operations are performed and each operating unit is again positioned at the time of starting.
゜ ～ 360 ゜ period (1 of cam 36 driving elevator 2)
Rotation). For example, in FIG.
The packaging is completed in the first half of two successive machine cycles, namely machine cycle 2 and machine cycle 3. Then, the product (b) is loaded onto the elevator 2 in the machine cycle 2 (period in the figure), and the film is pulled out and transported in the latter half of the machine cycle 2 (period in the figure). Also, in the first half (period in the figure) of the machine cycle 3, the product is lifted by the elevator 2 and the film ends are folded by the left and right folding plates A5 and the rear folding plate A6. Further, the products are discharged by the discharge pusher A7, and the labeling machine is used. The operation of attaching the label is performed. Now, paying attention to the machine cycle 2, the packaging of the product (a) is performed in parallel with the packaging of the product (b) described above. That is, the product (b) is carried in during the entire machine cycle 2 (period in the figure), and the film folding, discharging, and labeling of the product (a) are performed in the first half of the machine cycle 2 (period in the figure). Attachment is performed, and in the second half (period in the figure) of the machine cycle 2, the film is pulled out and transported for the product (b). (Refer to Fig. 4 for the operation timing of each unit within one machine cycle.)

FIG. 6 is a flowchart showing an outline of the start-up process, which is executed by the CPU 25. That is, 1 of the packaging machine
Immediately before the end of the packaging cycle, the following processing is executed. (SP1) Whether the product is placed on the weighing pan (product placement table). That is, it is determined whether the weighing value is “0”. (SP2) If the determination in (SP1) is "NO", that is, if a product is placed, it is determined whether the weighing value is stable. If the weighing value is not stable (if the determination in SP2 is "NO"), wait until the weighing value is stable. (SP3) ... If the determination in (SP2) is "YES", start the packaging machine. To start the operation of one packaging cycle to perform normal packaging processing. (SP4) On the other hand, if the determination in (SP1) is "YES", that is, if no product is placed on the weighing pan (product placement table), there is still unprocessed product inside the packaging machine. It is determined whether or not. That is, the operation of the previous packaging machine is the next S
It is determined whether or not the processing is for the final product in P5.
If the determination in (SP4) is "NO", that is, if there is no unprocessed product inside the packaging machine (SP1)
Return and wait for the product to be loaded. (SP5) If the determination of (SP4) is "YES", that is, if there is an unprocessed product inside the packaging machine, the packaging machine is activated to start the operation of one packaging cycle. The final product is packaged. In this case, the mechanism for carrying in the conveyor, extracting the film, and centering is not operated. (Because there is no product to be packed next, there is no need to operate the carry-in conveyor and pull out the film.)

In the above flowchart, the processing of (SP1) → (SP2) is “YES” → (SP3) in the first case of claim 1. The processing of (SP1) → (SP2) is “NO” → (SP3) Is the second case of claim 1 The processing of (SP1) → (SP4) → (SP5) is claim 1
This is the third case. FIG. 7 illustrates these cases. The first case [I] and the second case [II] are the same as the conventional case, but the third case [III] is different from the conventional case. That is, according to the present invention, when the product is not placed on the weighing pan (product placement table) at the end of the machine cycle and there is an unprocessed product inside the packaging machine, the next machine cycle is started immediately. You. On the other hand, conventional [IV]
If the product is not placed on the weighing pan (product placement table) at the end of the machine cycle, the next machine cycle is not started until the next product is placed and the weighing is stabilized.
Therefore, when the product conveyed in the machine cycle is the last product, it is necessary to start the machine cycle by operating the end switch (γ). As described above, according to the present invention, it is possible to automatically perform the packaging process of the last product without operating the end switch.

However, in the third case, there is a case where the product actually delivered in the machine cycle is really the last, and a case where the placement of the next product is not actually the last but is simply delayed. . FIG. 8 shows the relationship between the stability of placing and weighing the product and the machine cycle in this case. (A) The case of [III-] is the case of the last product, and the effects aimed at by the present invention can be obtained. (B) In the case of [III-] and [III-], the weighing is stabilized after the end of the machine cycle, and conventionally, after the end of the machine cycle, the apparatus is stopped until the weighing is stabilized. Therefore, executing the machine cycle has no adverse effect. (C) In the case of [III-], the time t until the machine cycle ends after the measurement stabilization β becomes a loss time as compared with the conventional case. Note that this time t itself is not so large, and in the case of [III-], there is a loss time t ′ from the end of the machine cycle to the time when the product is placed α, and Is not used at the maximum processing capacity, so that the influence of the existence of the loss time t on the performance of the apparatus can be substantially ignored. Therefore, in the case of [III-], the effect is obtained, and [III-]
], [III-], and [III-], there is no demerit, and according to the present invention, the desired effect can be obtained without sacrificing the performance of the device.

In the above embodiment, in the third case, the first
Unlike the second case and the second case, the product loading conveyor and the film centering-related mechanism are not operated (the last product packaging processing operation). However, it may be operated to perform idle operation. Further, in the embodiment, the goods are transported onto the elevator head in the first packaging cycle. With this configuration, it is necessary that the elevator head has completed lowering at least by the time the goods are loaded onto the elevator head, and if the processing speed is increased, the operating conditions of each operating unit may be severe. is there. In such a case, in the first packaging cycle, the commodities may be carried in just before the elevator, and then carried into the elevator head at the beginning of the second packaging cycle. Furthermore, in the embodiment, the packaging of one product is completed in two cycles (claim 4), but the present invention is not limited to this. For example, in the first time, the product is transported to the product standby position provided on the way of transport, and in the second time, the product is loaded onto the elevator head and the film is drawn out (the first time in the case of the embodiment), and the third is performed. The product may be pushed up, the end of the film folded, and discharged (the second time in the embodiment) at the third time, so that the packaging of one product may be completed in three cycles. (Case of Claim 5) In the embodiment, the label is attached while the product is being carried out by the discharge pusher. That is, labeling is performed in the second cycle. However, the film may be stuck in the third cycle after the product is carried out.
(Case of Claim 6) Furthermore, in the embodiment, the label is automatically attached while the product is being carried out by the discharge pusher, but the present invention is not limited to this. That is, a label may be manually affixed to the product after the product is carried out (after packaging is completed). (In the case of claim 8)

[0027]

In the first and second cases, the weighing / packaging apparatus according to the present invention continuously packs one product in a plurality of wrapping cycles as in the prior art. In the third case, that is, when the packaging cycle is completed (the operation of the packaging machine is completed), when there is no product on the weighing pan, and when the product is present inside the apparatus, the packaging is performed. The case in which the product inside the machine is the last product, and the case where the next product is not placed before the current packaging cycle is completed due to the work or the operator's convenience, which is not the last product. Therefore, in the case of the last product, the packaging process of the last product is executed without any special operation by the operator. If the product is not the last product, the next product is placed after or after the packaging process of the last product is completed. Then, the operation of the packaging machine is started. If a product is placed during the packaging process of the last product, the first or second case is reached, and the next packaging cycle is continued after the end of the packaging cycle. However, in this case, even if the weighing is stabilized, if the packaging cycle has not yet been completed, this period is a loss time compared to the conventional case, and the packaging capacity of the packaging machine is reduced. However, this period is generally a very short period, and when it does not normally correspond to the first and second cases, the packaging machine is not operated at the maximum processing capacity, so that the substantial effect can be ignored. Therefore, according to the present invention, it is possible to configure a weighing / packaging and pricing device that does not require the operator to perform any special operation even in the case of the last product without substantially affecting the processing capacity of the device. . For this reason, the work of the worker is simplified, and there is no possibility that the last product is left inside the apparatus for a long time due to forgetting the work.
