Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a baby-bulk-like article feeder that feeds baby-bulk-like articles such as rolled paper, and a device that packs a predetermined number of the articles into bags. The product is connected to the packaging machine via a transport line, and the products supplied from the supply machine are placed on the transport line and supplied directly to the packaging machine, allowing the process from supplying baby-shaped products to bagging the products to be carried out continuously. The present invention relates to a bagged article manufacturing apparatus and a control method thereof.

(Prior art) When bagging baby-bulk-shaped articles such as roll paper (hereinafter referred to as product logs), for example, 12 pieces (or 8 pieces, 16 pieces, etc., which are multiples of 4 of 8 or more), generally As shown in Figure 8, the product logs Q are arranged in 4 rows and in 3 stages in the log length direction (2 stages for 8 pieces, 4 stages for 16 pieces) to form a bag R.
The bagged article S is formed by being stored inside the container.

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 101 and a predetermined number (for example, 12
Packaging machine 1 that packs product logs Q (pieces) into bags
02 is connected by a product log conveyance line 103, and the product logs Q sequentially manufactured by the log cutting machine 101 are placed on the conveyance line +03 and supplied to the packaging machine 102 side, and the long logs P are cut and packed into bags. This is carried out using a bagging article manufacturing apparatus that can completely automate the metal process up to the manufacture of the article S (for example, Japanese Patent Application Laid-Open No. 134815/1983). In addition, in the manufacturing apparatus shown in FIG. 9, the log cutting machine 10
1, two rows of long logs P on the left and right are cut at the same time. In addition, a sorting device 106 is installed in the middle of the conveyance line 103 to sort the product logs Q conveyed in two rows on the left and right to the two upper and lower conveyors 105AS and 105B while maintaining the two rows. Packaging machine 10
A total of four product logs Q are lined up in a vertical plane at the second entrance (the exit of the two upper and lower conveyors 105A and 105B).

In addition, in the log cutting machine 101, since the log is cut with the cutting blade l12, there are problems such as generation of frictional heat and wear of the blade, and the upper limit of the cutting speed is limited (
For example, the processing capacity (packaging speed) for bagging product logs can be increased to a considerable speed (for example, up to 30 cutting times/minute) on the packaging machine 102 side. ), 1 log cutting JaIO
In a bagged article manufacturing apparatus that uses one packaging machine 102 for each bag, the packaging machine 102 currently has sufficient packaging capacity. 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.

In addition, in the conventional bagged goods manufacturing apparatus shown in FIG. 9, even though there is surplus capacity in the packaging speed on the packaging machine 102 side compared to the product log supply speed on the log cutting machine lot side, the surplus capacity is There was also the problem that it was not being used and was uneconomical.

In view of the problems of the conventional bagged article manufacturing apparatus mentioned in 1., the present invention connects two nodular article feeding machines to one packaging machine with a large capacity, and In addition to making effective use of excess packaging capacity, the packaging machine should continue to operate without stopping even if one of the two feeding machines is stopped as necessary. The purpose of the present invention is to propose an apparatus for manufacturing bagged articles and a method for controlling the same.

(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. and one packaging machine that sequentially packs the articles supplied from each of the first supply machines into bags in a predetermined number at a time in two lower tiers; an upper conveyance line for conveying the articles to a side article input position; and a lower conveyance line for conveying the articles supplied from the second feeder to the first article input position of the packaging machine; The above-mentioned -1-stage conveyance line and the above-mentioned lower stage conveyor line are a 1J-, hand side conveyor whose starting end is connected to the article discharge section of each feeder, and an F side conveyor whose terminal end is connected to the packaging machine side. It has a conveyor and a sorting conveyor that can move vertically between the slave side conveyor and the lower side conveyor, and the sorting conveyor on the upper conveyance line side and the sorting conveyor on the lower conveyance line side. are installed in vertical overlapping positions with each other, and the upper tier distribution conveyor is disconnected from the upper tier conveyor and the upper tier lower conveyor by the upper tier distribution drive device. A three-way evacuation position where the goods are transferred from the upper stage -1 - small side conveyor to - the lower stage conveyor 1 - where the goods are transferred to the upper stage -1 - small side conveyor connection position and the upper stage -1 - small side conveyor. The conveyor "2" is driven to the -L downward direction 3 position of the connection position of the lower stage lower side conveyor "2" to transfer the article to the F-stage hand side conveyor "2", and then the lower stage side conveyor (the J conveyor is : The lower stage sorting conveyor is transferred from the lower stage to the lower retracted position where the connection between the lower stage conveyor and the lower stage downstream conveyor is disconnected and the lower stage conveyor is retracted downward. Three positions in the vertical direction: a lower lower conveyor connection position where the article is transferred to the lower lower conveyor 2 and an upper lower conveyor connection position where the article transferred on the lower upper conveyor is transferred onto the upper lower conveyor. It is characterized by being configured so that it is driven by.

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 stop signal from the first feeder is received and the first feeder stops.
While the upper sorting drive device belonging to the feeder side maintains the upper sorting conveyor at the three-way retracted position, the lower sorting drive device moves the lower sorting conveyor between the lower side conveyor connection position and the upper lower side. It repeatedly moves up and down between the two positions with the side conveyor connection position, and when the second of the two feeders stops, the second feeder receives a stop signal from the second feeder and moves up and down repeatedly. While the lower sorting drive device belonging to the feeder side maintains the lower sorting conveyor in the lower retracted position, the upper sorting drive device moves the upper sorting conveyor to connect the upper and lower conveyor connection position and the lower lower conveyor. By repeatedly moving up and down between two positions with respect to the connection position, the articles fed from either one of the two feeders are sorted into the upper lower conveyor and the lower lower conveyor. Furthermore, when the operation of the stopped feeder is restarted, the operation restart signal of the feeder is received, and the drive unit moves the upper side feeder (J conveyor to the upper side lower side conveyor connection position). , and the lower side swing 1'3'
: It is characterized in that it is controlled so that the position is set at the connection position of the J conveyor or the lower conveyor.

(Function) In the bagged article manufacturing apparatus of the invention of claim 1, two article supply machines and one packaging machine are connected by two upper and lower conveyor lines, so that each supply machine can be The supplied articles are each 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.

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 capacity of the packaging machine's horn can be reduced. You will be able to use it effectively. Furthermore, in the intermediate portions of the upper conveyance line and the lower conveyance line that connect each feeding machine and the packaging machine, there are sorting conveyors that are positioned at three positions in the vertical direction by means of a sorting drive device. Even if one of the feeders stops, the distribution conveyor of the conveyance line belonging to the stopped feeder should not be moved in the way of the vertical reciprocation of the other distribution IJ conveyor. By repeatedly moving up and down the sorting conveyor of the conveyance line belonging to the feeder in operation while the conveyor is evacuated to a safe evacuation position, the articles fed from one feeder in operation are divided into two stages, upper and lower. It is possible to continue supplying to the packaging machine while sorting. Note that when only one feeder is operated, the article feeding 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 either one of the two feeders stops, a stop signal from the feeder causes the stopped supply to be stopped. After the sorting conveyor belonging to the machine side is evacuated to the evacuation position, the sorting conveyor belonging to the feeding machine side which is in operation moves up and down repeatedly, and the articles fed from the feeding machine which is in operation are automatically The products are then distributed to the upper and lower conveyors and then supplied to the packaging machine. Also, when the operation of the stopped supply machine is resumed, upon receiving the operation restart signal,
Since each sorting conveyor is connected to the downstream conveyor on the conveyance line, automation of operation restart can be achieved.

(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 conveying line and the lower conveying line are driven to three positions in the vertical direction by an upper sorting drive device and a lower sorting drive device, respectively, at positions where the upper conveying line and the lower conveying 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 running feeder will still be transferred to the sorting conveyor. It can be distributed to two stages, upper and lower, and supplied to the packaging machine, allowing continuous operation without interrupting the operation of the packaging machine (
This has the effect of eliminating time loss.

Further, according to the second invention of the present application, when one of the two feeders stops, upon receiving the stop signal, the sorting drive device operates the two sorting conveyors. is activated so that the goods fed from the running feeder can be sorted into two upper and lower stages 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, it is possible to achieve complete automation of the bag-packed article manufacturing apparatus.

Next, to explain the control method of the illustrated bagged goods manufacturing apparatus, when both log cutting machines 1A and 1B are operating normally, operation signals from both log cutting machines 1A and 1B (for example, motor rotation In response to the signal), the upper sorting cylinder 8A is maintained in an intermediately extended state to maintain the upper sorting conveyor 7A connected to the upper lower conveyor 5A, and the lower sorting cylinder 8B is also maintained in an intermediately extended state. Thus, the lower sorting conveyor 7B is maintained in a state connected to the lower lower conveyor 5B. In this state, the product logs Q cut by the first log cutting machine 18 are sequentially transferred to the upper conveyor 4A1.
The logs are transported by the upper sorting conveyor 7A and the bifurcated lower conveyor 5A to a position immediately before the upper article loading position 21 of the packaging machine 2 (stopped by a stopper 51A1), and are cut by the log cutting machine 1B of the other box 2. Similarly, the product log Q is sequentially transferred to the lower upper conveyor 4B, the lower sorting conveyor 7B, and the lower lower conveyor 5B.
The product is transported to a position just before the lower product loading position 22 of the packaging machine 2 (it is stopped by a stopper 51B+). At this time, each phototube 42A, 42A2, 72A of the upper transport line 3A and each phototube 42B of the lower transport line 3B.

42B, 72B detect the passing of the product log Q and are maintained in the ON state.

A predetermined number of product logs Q at each terminal end 5Ab, 5Bb of the upper and lower lower conveyors 5A, 5B.
is stocked (for example, the phototubes with symbols 52A and 52B are turned on), the symbols 51A and 51B2 (total 4
The stoppers 51A and 51B are used to restrict the passage of the fourth and subsequent product logs Q from the front, and the stoppers 51A and 51B are released, resulting in a total of 12 product logs, including the third product logs from the front. Q is supplied to the packaging machine 2, where it is packaged together with 1 as shown in FIG. Thereafter, after the stoppers 51A and 51B+ return to the traffic restriction state, the stoppers 51A2 and 51B are released, and in the same way, the product logs Q are placed in the packaging machine 2 in a predetermined number (12 pieces). ). In the normal operating state, the total product log supply speed of the two log cutting machines 1A and 1B is set so as not to exceed the packaging processing capacity of the packaging machine 2.

Next, when the operation of the first log cutting machine 1A is stopped, such as when the blade 12 is replaced, a new product log Q is no longer supplied to the upper transport line 3A side, and the product log Q is no longer supplied to the upper transport line 3A side. Photocell located 42 A+, 42
When Ax, 72A is turned off, the OFF signal from each phototube turns off the stopper 41A at the end of the upper upper conveyor 4A and the upper sorting conveyor 7A.
The stoppers 71A are actuated in the traffic regulation direction at the ends of the logs, and the upper sorting cylinder 8A is actuated by these signals (phototube OF'F signal and stopper actuation signal) and the stop signal of the first log cutting machine IA. When it is fully extended, the upper sorting conveyor 7A is maintained at the upper retracted position A 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. New product logs Q are not supplied to the upper and lower conveyor 5A side, and as the packaging work by the packaging machine 2 progresses, the product logs Q that have been stocked on the upper and lower conveyor 5A side decrease, and the phototube 5
When 2A enters the product log non-detection state (turns OFF), the OFF signal causes the phototube 52B on the lower conveyor 5B to remain in the ON state.
The lower sorting cylinder 8B is fully extended, and the lower sorting conveyor 7B is moved along the chain line 7E' in FIG.
Move it upward as shown in the lower stage sorting conveyor 7.
B is connected to the upper lower stage conveyor 5A side. Then,
The product logs Q supplied by the second log cutting machine 1B are sequentially supplied to the upper lower conveyor 5A via the lower sorting conveyor 7B and are stocked at the terminal end SAb. On the other hand, since no new product logs Q are supplied to the lower conveyor 5B side, the stock number decreases, and the phototube 52B turns OFF (the phototube 52A on the upper downstream conveyor 5A side is in the ON state) and the lower distribution cylinder 8B.
is reduced from the most extended state to the intermediate extended state, and the sorting conveyor 7B is transferred from the upper lower stage conveyor 5A side to the lower lower stage conveyor 5B side. While the first log cutting machine 1A is stopped, the above operation is repeated, and the product logs Q supplied from the second log cutting machine 1B are distributed to the upper and lower stages by the distribution operation of the lower stage distribution cylinder 8B. It is then alternately distributed and supplied to the side conveyor 5A side and the lower stage downstream side conveyor 5B side. Immediately after the lower sorting conveyor 7B is connected to the upper lower conveyor 5A, the auxiliary roller 9B is projected forward by the telescopic cylinder 10B (Fig. 6), and the terminal end 7Bb of the lower sorting conveyor 7B and the upper tier are extended. The gap formed between the starting ends 5Aa of the lower conveyor 5A is filled, and when the lower conveyor 7B starts its downward movement, the telescopic cylinder IOB immediately contracts and the auxiliary roller 9B
is moved to the downward retracted position.

Then, when the operation of the first log cutting machine lΔ that had been stopped is restarted, the lower tier side distribution cylinder 8B is maintained in the intermediate extended state in response to the operation restart signal (the lower tier side distribution conveyor 7B is 5B side), the upper stage sorting cylinder 8A returns from the most extended state to the intermediate extended state (the upper stage sorting conveyor 7A returns from the retracted position A to the upper lower conveyor connection position A). Then, the stopper 41A at the end of the upper-stage upper conveyor 4A and the stopper 71Δ at the end of the upper-stage sorting conveyor 7A are released, and the upper-stage conveyance line 3A and the lower-stage conveyance line 3B are completely passed through, and each log is cut. Machine 1A.

Each product log Q supplied from 1B passes through each conveyance line and is supplied to the packaging machine 2 side.

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 111B (the lower stage distribution conveyor 7B is moved to the downward retracted position). evacuate to B3),
Thereafter, the upper stage distribution cylinder 8A is repeatedly expanded and contracted between the intermediate extended state and the most contracted state, and the upper stage lower side conveyor connection position A connects the upper stage side distribution conveyor 7A to the upper stage lower side conveyor 5A side; and the lower conveyor connection position A3. When the operation of the lower log cutting machine 1B that had been stopped is restarted, the operation restart signal causes the upper stage distribution (J cylinder 8A to be in the intermediate extended state (the upper stage distribution conveyor 7A is switched to the upper stage lower side conveyor 5A). connection), then extend the lower sorting cylinder 8B from the most contracted state to the intermediate extended state (the lower sorting conveyor 7B
is connected to the lower stage conveyor 5B), and is normally operated by the two log cutting machines 1A and 1B.

As described above, according to the bagged goods manufacturing apparatus of this embodiment, when one of the two log cutting machines 1Δ and 1B is stopped, the other log cutting machine, which continues to operate, Since the product log Q supplied from the log cutting machine can be distributed and supplied to the upper and lower conveyors 5A and 5B, it is possible to feed the product logs Q to the lower conveyors 5A and 5B in the upper and lower tiers. Even if the operation of the 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.
