Description

Detailed Description of the Invention (Industrial Application Field) The present invention includes a baby-bulk-like article feeding machine that feeds baby-bulk-like articles such as roll paper, and a method of packaging a predetermined number of the articles into bags. The packaging machine is connected to the packaging machine via a conveyance line, and the goods supplied from the supply machine are loaded onto the conveyance line and fed directly to the packaging machine, allowing the process from supplying baby-shaped goods to bagging the goods to be carried out continuously. The present invention relates to a bagged article manufacturing apparatus and a control method thereof.

(Prior art) When packing baby-bulk-shaped articles such as roll paper (hereinafter referred to as product logs) into bags, for example, 12 pieces (or 8 pieces, 16 pieces, etc., multiples of 4 or more), generally As shown in Figure 8, the product log Q is
3 rows along the length of the log (2 rows for 8 pieces, 16 rows)
In the case of 4 tiers), they are stored in the bag R to form a bagged article S.

In addition, in recent years, when manufacturing a bagged article S made by bagging a predetermined plurality of roll papers, for example, as shown in FIG. 9, a long log P is sequentially cut into article (log) dimensions. Log cutting machine 1
01 and a predetermined number (for example, 12) of product logs Q as 1
A log cutting machine 10 is connected to a packaging machine 102 for bulk packing into bags by a product log conveyance line 103.
The product logs Q that are sequentially manufactured in step 1 are directly placed on the conveyor line 103 and supplied to the packaging machine 102 side, so that the entire process from cutting the long logs P to manufacturing the bagged articles S can be completely automated. This is done using a bag-packed product manufacturing device (for example, Japanese Patent Application Laid-Open No. 1983
−134815). In the manufacturing apparatus shown in FIG. 9, the log cutting machine 101 is designed to simultaneously cut two rows of long logs P on the left and right. In addition, a sorting device 106 is interposed in the middle of the conveying line 103 to sort the product logs Q conveyed in two rows on the left and right to the two upper and lower conveyors 105A and 105B while maintaining the two rows. , the entrance of the packaging machine 102 (the upper and lower conveyors 105A, 1
05B exit), a total of four product logs Q are lined up in a vertical plane.

In addition, in the log cutting machine 101, the cutting blade 1
12, the upper limit of the cutting speed is limited (for example, a maximum of 140 cuts/min) due to problems such as the generation of frictional heat and the wear of the blades. , the processing capacity for bagging product logs (packaging speed) can be increased to a considerable degree (e.g. up to
In a bagging product manufacturing apparatus that uses one packaging machine 102 for one log cutting machine 101, the packaging machine 102 has sufficient surplus packaging capacity. That is the current situation. In particular, if a large number of product logs, such as 12 or 16, are packed in bags in one packaging operation, more surplus bagging processing capacity will be created.

(Problems to be Solved by the Invention) By the way, in the conventional bagged goods manufacturing apparatus shown in FIG. However, if the operation of the log cutting machine is stopped in this way, the supply of the product log Q to the packaging machine 102 will also be stopped, which will inevitably interrupt the bagging operation in the packaging machine 102. There was a problem that this resulted in a loss of time.

Furthermore, in the conventional bagged goods manufacturing apparatus shown in FIG. There was also the problem that it was not being used and was uneconomical.

In view of the problems of the conventional bagged product manufacturing apparatus described above, the present invention connects two nodular product supply machines to one packaging machine with a large capacity, thereby increasing the packaging capacity of the packaging machine. In addition to making it possible to effectively utilize the surplus capacity of the machine, even if one of the two feeding machines is to be stopped as necessary, the packaging machine can be operated continuously without having to stop. It is an object of the present invention to provide a manufacturing apparatus for bagged articles and a control method thereof.

(Means for Solving the Problems) The bagged article manufacturing apparatus of the first invention of the present application includes two baby-boom-like article feeders, a first and a second, which sequentially and continuously supply baby-boom-like articles. a packaging machine that sequentially packs a predetermined number of articles supplied from each of the supply machines into bags in upper and lower stages; an upper conveyance line for conveying to the loading position;

A lower conveyor whose terminal end is connected to the packaging machine side,
A sorting conveyor is provided that is movable in the vertical direction between the upper conveyor and the lower conveyor, while the sorting conveyor on the upper conveying line side and the sorting conveyor on the lower conveying line are vertically movable with respect to each other. The upper-stage sorting conveyor is installed in the overlapping position, and the upper-stage sorting conveyor disconnects the upper-stage upper-side conveyor and the upper-stage lower-side conveyor and retreats upward by the upper-stage sorting drive device. An upper lower conveyor connection position for transferring the articles transferred on the side conveyor onto the upper lower conveyor, and a lower lower conveyor connection position for transferring the articles transferred on the upper upper conveyor onto the lower lower conveyor. The lower tier sorting conveyor is driven to three positions in the vertical direction, and the lower tier sorting conveyor disconnects the lower tier upper conveyor from the lower tier lower conveyor and retreats downward by the lower tier sorting drive device. a lower tier lower conveyor connection position for transferring the articles transferred on the lower tier upper conveyor onto the lower tier lower conveyor; and an upper tier for transferring the articles transferred on the lower tier upper conveyor onto the upper tier lower conveyor. It is characterized in that it is configured to be driven in three positions in the vertical direction including the lower conveyor connection position.

Further, the method for controlling the bagged article manufacturing apparatus according to the second invention of the present application uses the bagged article manufacturing apparatus according to the first invention of the present application, and the two feeding machines are both in normal operation. When the system is in use, the upper tier sorting drive device and the lower tier sorting drive device are used to maintain the upper tier sorting conveyor at the upper tier lower side conveyor connection position and the lower tier side distribution conveyor at the lower tier lower side conveyor connection position, respectively. When the first of the two feeders stops, the upper sorting conveyor is activated by the upper sorting drive device belonging to the first feeder in response to the stop signal of the first feeder. is maintained in the upper retracted position, the lower sorting conveyor is moved up and down repeatedly between the two positions of the lower conveyor connecting position and the upper lower conveyor connecting position by the lower sorting drive device, and When the second feeder out of the two feeders stops, the lower-side sorting drive device belonging to the second feeder receives the stop signal from the second feeder and starts the lower-side sorting conveyor. While maintaining the lower evacuation position, the upper distributing drive device moves the upper distributing conveyor up and down repeatedly between two positions: the upper lower conveyor connection position and the lower lower conveyor connection position. The articles supplied from either one of the feeders are distributed to the upper and lower conveyors, and when the stopped feeder resumes operation, the operation of that feeder is changed. Upon receiving the restart signal, each sorting drive device moves the upper sorting conveyor to the connection position of the upper lower conveyor.
Further, the present invention is characterized in that the lower tier sorting conveyors are controlled to be positioned at the lower tier downstream conveyor connection positions, respectively.

(Function) In the bagged article manufacturing apparatus of the invention of claim 1, two article feeding machines and one packaging machine are arranged in upper and lower positions.
Since they are connected by conveyance lines in stages, the articles supplied from each feeder are conveyed to the packaging machine side by each conveyance line, and the articles are packed into bags in a predetermined number by the packaging machine. Ru. In addition, the product packaging capacity of the packaging machine is considerably larger than that of a single feeder, and by connecting two feeders to the packaging machine, the excess packaging capacity of the packaging machine can be utilized. Make effective use of it. moreover,

Even if one of the two feeders stops, the distribution conveyor of the conveyance line belonging to the stopped feeder should be evacuated if it gets in the way of the other distribution conveyor reciprocating up and down. By repeatedly moving up and down the sorting conveyor of the conveyor line belonging to the feeding machine in operation while the goods are being evacuated to the position, the goods fed from one feeding machine in operation are sorted into two stages, upper and lower. It is possible to continue supplying to the packaging machine. Note that when only one feeder is operated, the article supply speed is halved compared to when both feeders are operated, and the packaging machine's article packaging speed is reduced; however, the packaging machine continues to operate without interruption. be driven.

Further, according to the method for controlling a bagged article manufacturing apparatus according to the second aspect of the invention, when one of the two feeders stops, the stop signal of the feeder causes the stop signal to stop. After the sorting conveyor belonging to the feeding machine side that has been moved has retreated to the evacuation position, the sorting conveyor belonging to the feeding machine side that is in operation moves up and down repeatedly, and the articles fed from the feeding machine that is in operation is automatically distributed to the upper and lower conveyor side and the lower and lower conveyor side, and is then supplied to the packaging machine. Furthermore, even when the stopped feeder resumes operation, each sorting conveyor is connected to the downstream conveyor on the corresponding transport line in response to the operation restart signal, achieving automation in restarting operation. can.

(Effects of the Invention) In the first invention of the present application, since two baby-boom-shaped article feeding machines are connected to one packaging machine, the excess packaging capacity of the packaging machine can be effectively utilized. It is possible to reduce equipment costs and improve the manufacturing speed of bagged articles. Further, in the first aspect of the present invention, the upper conveyance line and the lower conveyance line are driven to three positions in the vertical direction by an upper distribution drive device and a lower distribution drive device, respectively, at positions where the upper conveyance line and the lower conveyance line overlap each other in the vertical direction. Since an upper sorting conveyor and a lower sorting conveyor are installed, even if one of the two feeders stops, the goods fed from the feeder that is in operation will still be handled.
It is possible to distribute the product into two stages, upper and lower, using a sorting conveyor and supply it to the packaging machine, which has the advantage that the packaging machine can be operated continuously without interruption (time loss is eliminated).

Further, according to the second invention of the present application, when one of the two feeders stops, each of the above-mentioned sorting conveyors is operated by the sorting drive device in response to the stop signal. The system is designed so that the goods fed from the running feeders can be sorted into two levels, upper and lower, by the sorting conveyor, so if one of the two feeders stops, However, if each sorting conveyor is automatically activated, and if the stopped feeder restarts operation, each sorting conveyor receives the operation restart signal and starts each downstream conveyor of the conveyance line. Since the apparatus is connected to the apparatus, there is an effect that complete automation of this bagged article manufacturing apparatus can be achieved.

When any one of _A3 is in the OFF state (when the upper stage distribution cylinder 8A is in the maximum extension state or the intermediate extension state), it is contracted and the auxiliary roller 9A is maintained in the downward retracted state. , when both the second and third auto switches 81A ₂ , 81A ₃ are turned on at the same time (the upper stage distribution cylinder 8A is in the most contracted state), the signals are emitted from both the auto switches 81A ₂ , 81A ₃ . After a short period of time (for example, 0.5 seconds), the auxiliary roller 9A is extended (10A' in FIG. 7) and projected forward of the end of the upper sorting conveyor 7A' as indicated by 9A'. Operate. Incidentally, at the same time that the upper stage side distribution cylinder 8A starts the extension operation from the most contracted state, the second or third
The auto switch 81A ₂ or 81A ₃ is turned OFF, and the telescopic cylinder 10A is immediately retracted by the signal. On the other hand, the telescopic cylinder 10B (FIG. 6) on the side of the lower sorting conveyor 7B is also activated by either one of the first and fourth auto switches 81B ₁ and 81B ₄ on the side of the lower sorting cylinder 8B.
When in the OFF state (when the lower sorting cylinder 8B is in the most contracted state or in the intermediately extended state), it is contracted and maintains the auxiliary roller 9B in the downward retracted state, and the first and fourth automatic When both switches 81B ₁ and 81B ₄ are turned ON at the same time (lower stage distribution cylinder 8B is in the maximum extension state), both auto switches 81B ₁ and 81
After receiving the signal emitted from _B4 , the auxiliary roller 9B is extended (10B' in FIG. 6) after a short time (for example, 0.5 seconds) and moved to the end of the lower sorting conveyor 7B' as shown by 9B'. It works by projecting it forward. Incidentally, the telescopic cylinder 10B is also immediately reduced in size by the signal from the first or fourth auto switch 81B ₁ or 81B ₄ which is turned OFF at the same time as the lower distribution cylinder 8B starts its reduction operation.

Next, to explain the manufacturing method of the illustrated bagged article manufacturing apparatus, when both log cutting machines 1A and 1B are operating normally, both log cutting machines 1A and 1B are operated normally.
In response to operation signals (for example, motor rotation signals) from A and 1B, the upper sorting cylinder 8A is maintained in an intermediately extended state, and the upper sorting conveyor 7
A is maintained in a state connected to the upper stage lower side conveyor 5A side, and the lower stage side distribution cylinder 8B is also maintained in an intermediate extended state to maintain the lower stage side distribution conveyor 7B in a state connected to the lower stage lower side conveyor 5B side. Do it like this. In this state, the first
The product log Q cut by the log cutting machine 1A is sequentially conveyed to a position immediately before the upper article loading position 21 of the packaging machine 2 by an upper upper conveyor 4A, an upper sorting conveyor 7A, and an upper lower conveyor 5A. (stopped by a stopper _51A1 ), and the product log Q cut by the second log cutting machine 1B is similarly sequentially transferred to the lower upper conveyor 4B, the lower sorting conveyor 7B, and the lower lower side. It is conveyed by the conveyor 5B to a position immediately before the lower article input position 22 of the packaging machine 2 (symbol 5
1B ₁ stopper). At this time, each phototube 42A ₁ , 4 of the upper conveyance line 3A
The phototubes 2A ₂ , 72A and the phototubes 42B ₁ , 42B ₂ , 72B on the lower conveyance line 3B side detect the passage of the product log Q and are maintained in the ON state.

A predetermined number of product logs Q are stored at each terminal end portion 5Ab, 5Bb of each of the upper and lower lower conveyors 5A, 5B (for example, a number 52
A, 52B photocells turn on) and code 51
While the stoppers A ₂ and 51B ₂ (4 in total) are restricting the passage of the fourth product log Q from the front, the stoppers 51A ₁ and 51B ₁ are released and the product log Q is the third from the front. A total of 12 product logs Q are supplied to the packaging machine 2, where they are packaged as 1 as shown in FIG. after that,
After the stoppers with codes 51A ₁ and 51B ₁ return to the traffic restriction state, the stoppers with codes 51A ₂ and 51B ₂ are released, and in the same way, the product log Q
is controlled so that a predetermined number (12 pieces) of the pieces are packaged on the packaging machine 2 side. In the normal operating state, the total product log supply speed on the two log cutting machines 1A and 1B is set so as not to exceed the packaging processing capacity on the packaging machine 2 side.

Next, for example, when the operation of the first log cutting machine 1A is stopped, such as when the blade 12 is replaced, no new product logs Q are supplied to the upper transport line 3A side, and the product logs Q are placed on the upper transport line 3A side. The phototubes 42A ₁ , 42A ₂ , and 72A are turned OFF, and the OFF signal from each phototube causes the stopper 4 at the end of the upper conveyor 4A to be turned off.
1A and the stopper 71A at the end of the upper sorting conveyor 7A are activated in the traffic regulation direction, and furthermore, those signals (phototube OFF signal and stopper activation signal) and the first log cutting machine 1 are activated.
Due to the stop signal of A, the upper stage distribution cylinder 8
A is extended to the maximum extent, and the upper sorting conveyor 7A is maintained at the upper retracted position _A1 as shown in FIG. In this state, the lower sorting conveyor 7B is connected to the lower downstream conveyor 5B, and the product logs Q sequentially supplied by the second log cutting machine 1A are supplied as they are to the lower downstream conveyor 5B. Upper stage lower side conveyor 5
No new product log Q is supplied to the A side, and as the packaging machine 2 progresses with the packaging work, the product log Q stored on the upper and lower conveyor 5A side decreases, and the phototube 52A is supplied with the product log Q. When it enters the non-detection state (turns OFF), the OFF signal causes the lower distribution cylinder 8B to be extended to the maximum (at this time, the phototube 52B on the lower side conveyor 5B is maintained in the ON state). , the lower sorting conveyor 7B is moved upward as shown by the chain line 7B' in FIG. 4, and the lower sorting conveyor 7B is connected to the upper and lower conveyor 5A. Then, the product logs Q supplied by the second log cutting machine 1B are sequentially transferred to the lower sorting conveyor 7.
It is supplied to the lower conveyor 5A side of the upper stage via B, and is stored at the terminal end 5Ab side. On the other hand, since no new product log Q is supplied to the lower downstream conveyor 5B, the stock number decreases and the phototube 52B is turned OFF (the upper downstream conveyor 5B).
The phototube 52A on the A side is in the ON state) and the lower sorting cylinder 8B are contracted from the most extended state to the intermediate extended state, and the sorting conveyor 7B is moved from the upper lower hand conveyor 5A side to the lower lower hand conveyor 5B.
Begins to switch to the other side. First log cutting machine 1
While A is stopped, the above operation is repeated, and the product logs Q supplied from the second log cutting machine 1B are distributed between the upper and lower conveyor 5A side and the lower stage by the sorting operation of the lower sorting cylinder 8B. It is then alternately distributed and supplied to the lower conveyor 5B side. Immediately after the lower sorting conveyor 7B is connected to the upper lower conveyor 5A, the auxiliary roller 9 is moved by the telescopic cylinder 10B (Fig. 6).
B is projected forward to fill the gap formed between the terminal end 7Bb of the lower sorting conveyor 7B and the starting end 5Aa of the upper lower side conveyor 5A,
Further, when the lower sorting conveyor 7B starts its downward movement, the telescopic cylinder 10B immediately contracts to move the auxiliary roller 9B to the downward retracted position.

Then, when the operation of the first log cutting machine 1A which had been stopped is restarted, the lower stage side distribution cylinder 8B is maintained in the intermediate extended state in response to the operation restart signal (the lower stage side distribution conveyor 7B is 5B), the upper sorting cylinder 8A returns from the most extended state to the intermediate extended state (the upper sorting conveyor 7A returns to the upper retracted position).
(returns from A ₁ to upper/lower conveyor connection position A ₂ )
Then, the stopper 41A at the end of the upper upper conveyor 4A and the upper sorting conveyor 7
The stopper 71A at the end of A is released, the upper conveyance line 3A and the lower conveyance line 3B are completely passed through, and each log cutting machine 1A,
Each product log Q supplied from 1B is supplied to the packaging machine 2 side through its respective conveyance line.

Further, when the operation of the second log cutting machine 1B is stopped, the lower stage distribution cylinder 8B is minimized in response to the stop signal of the second log cutting machine 1B (the lower stage distribution conveyor 7B is retracted downward). After _that , the upper sorting cylinder 8A is repeatedly expanded and contracted between the intermediate extended state and the most contracted state, and the upper sorting conveyor 7A is connected to the upper lower conveyor 5A. It operates so as to repeatedly swing between the upper stage lower side conveyor connection position _A2 and the lower stage lower side conveyor connection position _A3 . When the operation of the stopped lower log cutting machine 1B is resumed, the operation restart signal causes the upper sorting cylinder 8A to be in an intermediate extended state (the upper sorting conveyor 7A is connected to the upper lower conveyor 5A). After this, the lower sorting cylinder 8B is extended from the most contracted state to the intermediate extended state (the lower sorting conveyor 7B is connected to the lower lower conveyor 5B), and the two log cutting machines 1A and 1B are operated normally. be done.

As described above, according to the bagged product manufacturing apparatus of this embodiment, when one of the two log cutting machines 1A and 1B is stopped,
Since the product log Q supplied from the other log cutting machine that continues to operate can be distributed and supplied to the lower conveyors 5A and 5B of the upper and lower tiers, for example, when changing blades, etc. Even when the operation of one log cutting machine is interrupted, the other log cutting machine can be operated as is, and the packaging machine can also be operated continuously.
Also, according to this control method, when the operation of one of the log cutting machines is stopped, or when the operation of the stopped log cutting machine is restarted, those signals (operation stop signal, operation restart signal) are activated. Since the sorting conveyors 7A and 7B are operated by the operator, switching of the sorting conveyors can be automated.
