Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a manufacturing line in which an article manufacturing machine (for example, a log cutting machine) and a packaging machine are continuous, for example, when manufacturing bagging roll paper. In particular, the present invention relates to an article storage device used for the purpose of temporarily storing articles sequentially manufactured by an article manufacturing machine before being supplied to the packaging machine side.

(Prior Art) In recent years, in the industry of manufacturing roll paper, a series of production lines in which all the processes from the base paper roll to the production of a bag product as a final product are automated have become widespread.
For example, as shown in FIG. 9, in the log winder P, a small-diameter long log W is manufactured from a base paper roll, and the long log W is placed on a conveyor Pa and supplied to a long log storage device Q. Therefore, after temporarily storing, the long log W is sequentially supplied from the long log storage device Q to the log cutting machine R, and the long log W is cut into product dimensions there, and the log X is conveyed by the conveyor T.
The product is placed on a, conveyed to the packaging machine T side, and packed into a final product in the packaging machine T. As shown in FIG. 10, the long log storage device Q interposed between the log winder P and the log cutting machine R stores the long log W supplied from the log winder side, 1 is sequentially applied to a large number of article receiving members Qb attached to the endless chain Qa which is circulated in a zigzag manner.
The long logs W held in the article receiving member Qb are sequentially supplied to the log cutting machine R side in synchronism with the operation of the log cutting machine R. Has become. As described above, in the production line in which the long log storage device Q is interposed between the log winder P and the log cutting machine R,
For example, even if the winding work is interrupted on the log winder P side due to a roll change of the base paper or a paper jam, the long logs W stocked in the long log storage device Q are sequentially transferred to the log cutting machine R side. Since it is supplied, it is possible to continue the operation without stopping the log cutting machine R until there is no long log W stocked in the long log storage device Q, and conversely, log cutting Even if the cutting operation is interrupted on the side of the machine R due to the change of the blade, the winding operation of the log winder P is not interrupted until the long log W is full in the long log storage device Q. The log winder can be operated continuously.

However, in the conventional production line for producing the rolled paper roll, as shown in FIG. 9, a product log storage device for storing the product log X is provided between the log cutting machine R and the packaging machine T. It is not installed, and the log cutting machine R and the packaging machine T are directly connected. Therefore, for example, when the log cutting operation is interrupted on the log cutting machine R side, the supply of articles to the packaging machine T side is stopped, and the bag packing operation on the packaging machine T side is inevitably stopped, or conversely, on the packaging machine T side. When a trouble occurs and the packaging work is stopped, the operation of the log cutting machine R must be interrupted to stop the supply of the article (product log), resulting in a time loss. In the production line shown in FIG. 9, the long log storage device Q installed between the log winder P and the log cutting machine R is
Since the handling target is the long log W, when the long log W is loaded into the storage device Q side or discharged from the storage device Q, one long log W is entirely loaded or Since it can be discharged and handled easily, it can be configured with a relatively simple mechanism. However, when installing the product log storage device between the log cutting machine R and the packaging machine T, Because the handled product is the short product log X,
It is inefficient to insert or discharge the product logs X one by one into or from the article receiving member, and a plurality of product logs X, X ...
(For example, the number of product logs taken per long log: 7-8
If you try to insert or eject each of these) into the article receiving member at the same time, some of them will fall off without being held by the article receiving member, and each product log will be ejected separately when ejecting the article. It is expected to occur, and currently there is no production line with a product log storage device installed between the log cutting machine and the packaging machine. It is also conceivable to store a product log by substituting a long log storage device Q as shown in FIGS. 9 and 10 between the log cutting machine R and the packaging machine T. In that case , The product logs held on each article receiving member of the product log storage device are in linear contact with each other, and are ejected onto the conveyor leading from the article receiving member side to the packaging machine side at the product log ejection position. When each product log falls with a time lag (for example, the product log located on the lower side in the conveyor running direction falls earlier than the product log located on the lower side in the conveyor running direction), or the dropped product log When the product bounces on the conveyor, product logs may overlap vertically on the conveyor, and the product logs may overlap each other on the packaging machine side. A problem that becomes impossible packaging in to be sent packing machine occurs.

(Object of the Invention) In view of the above-mentioned conventional problems, the present invention stores a large number of sets of articles at the same time in a state in which one unit of articles is arranged in a line between the article manufacturing machine and the packaging machine. It is possible to install an article storage device adapted to do so, and in such an article storage device, one unit of the number of articles discharged onto the conveyor leading from the article discharge position to the packaging machine side is the conveyor. The purpose is to prevent them from overlapping each other.

(Means for Achieving the Object) The present invention provides an endless article receiving member having a length capable of holding a plurality of articles in a line between a pair of endless chains horizontally arranged at a predetermined interval. A large number of the endless chains are provided at predetermined equal intervals in the chain length direction, and the endless chain is driven by an article receiving side driving device and an article discharging side driving device to continuously supply the respective article receiving members from the article manufacturing machine. Between an article loading position at which an article group having a predetermined number of articles as one unit is loaded into the article receiving member and an article discharging position at which the article group held in the article receiving member is discharged from the article receiving member Further, the length range from the article input position in the endless chain to the article discharge position around the lower side in the endless chain running direction is defined as the article storage section and from the article discharge position in the endless chain. On the other hand, the length range from the endless chain running direction to the article loading position is set as the article empty portion, and the lengths of the article storage section and the article empty section can be relatively changed by the length adjusting mechanism. The article groups supplied to the article loading position by the article feeding apparatus are sequentially loaded by the article loading apparatus into the empty article receiving members, and the article groups are held in the respective article receiving members located in the article storage section. Further, in an article storage device capable of sequentially ejecting the article group held in each of the article receiving members onto a conveyor leading to the packaging machine side by the article ejection device at the article ejection position, directly below the article ejection position. An article guide passage for guiding the article group discharged from the article receiving member onto the conveyor in a state parallel to the traveling direction of the conveyor, and one article guide passage A plurality of shutter members that are individually opened and closed by dividing them into length ranges, and a plurality of operating devices that individually operate each shutter member, and are discharged from the article receiving member when the shutter members are closed. A plurality of opening / closing devices, each of which supports a unit number of articles by each shutter member and allows the articles supported on the shutter member to drop onto the conveyor when the shutter member is opened, and each opening / closing device. Is provided with an article temporary receiving device provided with a control device for sequentially opening the conveyors on the lower side in the traveling direction of the conveyor with a time lag.

(Operation) The article storage device of the present invention is interposed between the article manufacturing machine and the packaging machine, and supplies a predetermined number of articles conveyed on the conveyor from the article manufacturing machine side to the article loading position. ,
An article group including a predetermined number of articles supplied to the article loading position as one unit is loaded by the article loading device into the article receiving member waiting at the article loading position. When a group of articles is loaded into the article receiving member waiting at the article loading position, the article receiving side driving device is actuated next, and the endless chain on the article empty portion side travels by the distance between two adjacent article receiving members. Then, each of the article receiving members on the empty side of the article is moved by one pitch, and the next group of articles is conveyed onto the conveyor at the article loading position. A group is held and a large number of article groups are stored on the side of the article storage section. On the other hand, at the article discharge position side, when the article discharge side drive device is operated, the endless chain on the article storage section side is caused to run, and at that time, it is held in the article receiving member at the article discharge position by the article discharge device. The article group is discharged from the article receiving member. An article temporary receiving device is provided immediately below the article discharge position,
The articles ejected in a line from the article receiving member at the article ejecting position are supported one by one on each shutter member of the article temporary receiving device. Then, when one unit of articles is temporarily held on each shutter member of the article temporary receiving device, each opening / closing device that individually opens / closes each shutter member according to a command from the control device is directly below the article discharge passage. The shutter member opening operation direction is sequentially operated with a predetermined time difference (for example, 0.4 to 0.5 seconds difference) from the one located on the lower side of the traveling direction of the conveyor. Then, each article held on each shutter member comes to fall on the conveyor with a time lag sequentially from the one located on the lower side in the conveyor traveling direction, at which time the conveyor travels toward the packaging machine side. Therefore, the article that has dropped onto the conveyor first has already advanced a predetermined distance to the lower side of the conveyor running direction when the article that follows it has dropped onto the conveyor, and therefore the article that will fall onto the conveyor later will come first. It does not overlap with the items that have fallen into the area. Then, the group of articles discharged onto the conveyor at the article discharge position is transferred to the packaging machine side by riding on the conveyor. Further, when the chain pulling speed on the article receiving side driving device side is faster than the chain pulling speed on the article discharging side driving device side, the length of the chain on the article storing part side is increased by the length adjusting mechanism, and the article storing part When the number of articles stored on the side increases, and conversely the chain pulling speed on the article discharge side drive unit is faster than the chain pulling speed on the article receiving side drive unit side, the chain length on the article storage unit side Becomes shorter and the number of articles stored in the article storage section decreases, and the processing speed of each apparatus of the article manufacturing machine in the pre-process and the packaging machine in the post-process of this article storage device. According to the above, there is an effect that the speed of loading the article group into the article storage section or the speed of discharging the article group from the article storage section can be adjusted.

As a result, the article receiving member 14 can be tilted on the spot (fixed position), and the article group Y on the tray 17 can always be dropped to the fixed position. When discharging a group of articles on the tray, on the contrary, the article receiving member side is moved continuously to abut the rocking piece against the fixed abutting member. If the product is tilted, there may be a difference in the time when the article group is rolled out for each article receiving member, and the falling position of the article group cannot be determined due to the continuous movement of the article receiving member. In addition, in the case of discharging a group of articles including a plurality of product logs as described above, there is a problem that the transfer time may be different for each product log and the drop position may be different for each product log. . When the drop position of each article group or the drop position of each product log is deviated as described above, it is necessary to widen the width of the article receiving port that receives the deviation, which increases the installation space of the article receiving material.

Immediately below the article discharge position B, as shown in FIGS. 7 and 8, a conveyor 71 that communicates each of the article groups Y, Y discharged from the two article receiving members 14, 14 to the packaging machine T side.
Article temporary receiving devices 6 and 6 are provided for temporarily temporarily receiving the product logs X, X, ... Of the article group Y before dropping them upward and sequentially dropping them with a time lag.
Each of the article temporary receiving devices 6 and 6 includes an article receiving member 61 which is an article guiding passage 60 provided immediately below the dropping position of each of the article groups Y and Y, and a bottom opening 62 of the article receiving member 61. A plurality of division opening / closing devices (the same number as the number of product logs of one unit discharged from the article receiving member 14) that can be opened and closed by dividing the product logs X, X ... Switchgear) 63A to 63H and each of the switchgear 6
It has a control device (controller) 10 for sequentially operating 3A to 63H individually. Each of the first to eighth opening / closing devices 63A to 63H has a shutter plate (which serves as a shutter member within the scope of the utility model registration claim) 65A to 65H having an area capable of supporting one product log X, respectively. The cylinders 64A to 64H project and retract in the bottom opening 62 of the article receiving member 61 so that the bottom opening 62 can be divided into the length ranges of one product log X and individually opened and closed. Further, the first to eighth opening / closing devices 63A to 63H are arranged on the lower side (the arrow L side in FIG. 8) in the traveling direction of the conveyor 71 stretched below the article receiving member 61 in response to a signal from the controller 10. A slight time difference from what is located (for example, 0.
The shutter plate is operated to open sequentially with a difference of 4 to 0.5 seconds. That is, in this embodiment, as shown in FIG. 8, the expansion / contraction operation switching solenoid valve 66 is provided in each of the air cylinders 64A-64H of the opening / closing devices 63A-63H.
A to 66H are provided, and each of the solenoid valves 66A to 66H is controlled by a signal from the controller 10 so that the solenoid valves 66A to 66H are operated so as to be sequentially reduced with a slight time difference from the side of the air cylinder 64A located on the lower side in the traveling direction of the conveyor 71. ing. Two left and right article temporary receiving devices 6 and 6
The switchgear is adapted to operate simultaneously with one another. In FIGS. 7 and 8, reference numeral 67 is a guide roller for moving the shutter plates (65A to 65H) forward and backward in a horizontal posture.

The temporary article receiving devices 6 and 6 have the following actions. That is, when the air cylinder 41 of the article ejecting device 4 is expanded and contracted, the article groups Y, Y held by the two article receiving members 14, 14 at the article ejecting position B are respectively moved to the article temporary receiving device 6 , 6 article receptacle members 61, 61
The product logs X, X.
. Is placed on the shutter plates 65A to 65H of the opening / closing devices 63A to 63H, respectively.
Is placed on each of the shutter plates 65A to 65H,
The temporary article receiving device 6,
Each of the opening / closing devices 63A to 63H of No. 6 sequentially opens the shutter plate with a slight time difference from the opening / closing device 63A side located on the lower side (arrow L side) in the traveling direction of the conveyor 71. In this way, when the shutter plate 65A on the opening / closing device 63A side located on the arrow L side on the conveyor 71 is sequentially opened, the arrow Y side of the article group Y temporarily held in the article receiving member 61 is opened. The product logs X that are positioned are sequentially dropped onto the conveyor 71, and the product logs X that have dropped onto the conveyor are placed on the conveyor 71 by the time difference until the opening / closing device is opened next, and the product log X is moved downward in the traveling direction. When the next product log X is dropped on the conveyor 71, the preceding product log X has been moved to the lower side by the distance H in FIG. When falling onto 71, the product log X that has dropped first has moved by the distance H, so that the product logs X, X, ... Do not overlap each other on the conveyor 71. If the temporary article receiving device 6 is not provided, the product logs X, X ... Of the article group Y discharged from the article receiving member 14 are directly conveyed with a time difference between them in a continuous row. 71. At this time, for example, if an article located on the upper side in the conveyor running direction falls faster than an article located on the lower side in the conveyor running direction, or the dropped product log X bounces on the conveyor. , Part of adjacent product logs X, X may overlap each other. When the product logs X, X are conveyed to the packaging machine T side as they are polymerized in this way, there arises a problem that the packaging machine T cannot be bagged and the bagging operation is interrupted. As in the example, by providing the article temporary receiving device 6, such a trouble can be solved in advance.

The product logs X, X, ... Dropped from the temporary article receiving devices 6 and 6 onto the conveyor 71 are sequentially conveyed to the packaging machine T side and are packed into a predetermined number of bags there to form a final product.

The product log storage device S is installed between the log cutting machine R and the packaging machine T that form a continuous production line, but when the log cutting machine R and the packaging machine T are normally operating (log cutting). The product log production speed of the machine and the product log bagging processing speed of the packaging machine are the same), the number of product logs received from the log cutting machine R side to the product log storage device S and the product log storage device S to the packaging machine T side. In order that the number of product logs to be discharged to the same is the same, the driving speed of the article receiving side driving device 11 (running speed of the article receiving side endless chain) and the driving speed of the article discharging side endless drive device (running of the article discharging side endless chain) Speeds) are set to be equal to each other. Since the article group is discharged simultaneously from the two article receiving members 14, 14 on the article discharge side, the article discharge device 4 operates once every time the endless chain 13 on the article discharge side travels two pitches. You can do it. By the way, when operating for a long time, it may be necessary to interrupt the operation of either the log cutting machine R or the packaging machine T. When the operation is interrupted, the drive of the article receiving side drive device 11 is interrupted while the article discharge side drive device 12 is being driven (note that
The article receiving side drive device 11 does not automatically operate when the supply of the product log X is stopped). Then, although the storage device S side does not newly receive the product log, the operation of the packaging machine T is stopped by discharging the product logs X, X ... Stored in the receiving member circulation device 1 as they are as usual. It can be operated continuously without. When the operation of the log cutting machine R is restarted after the repair of the log cutting machine R, the article receiving side drive device 11 is also restarted, and the article group Y is received in the receiving member circulating device 1. At the beginning of the resumption of acceptance of the article group Y, the article group Y stocked in the receiving member circulating apparatus 1 has decreased, and a predetermined standard number of article groups in the receiving member circulating apparatus 1 have been reduced. Until Y is stored, the amount of articles received may be larger than the amount of articles discharged. (For example, the log cutting speed of the log cutting machine R is temporarily increased to increase the product log supply amount to the product log storage device side). On the contrary, when the operation of the packaging machine T is interrupted, the drive of the article discharge side drive device 12 is stopped, and the log cutting machine R can be continuously operated until the excess storage portion in the receiving member circulation device 1 is filled. . still,
When the operation of the packaging machine T is interrupted, the amount of articles received into the receiving member circulation device 1 increases, but if the bagging speed of the packaging machine is made faster than the normal speed at the beginning of the restart of the operation of the packaging machine, the receiving member The stock amount of articles in the circulation device 1 can be returned to an appropriate level.

In this way, if the product log storage device S is provided between the log cutting machine R and the packaging machine T, even if the operation of either the log cutting machine R or the packaging machine T is interrupted, the product log storage device S Since the loading and unloading of articles can be adjusted at a part, the other machine can be continuously operated as it is, and the manufacturing efficiency is improved.

(Effect of the Invention) The article storage device of the present invention is provided with the shutter members 65A to 65H of the article temporary receiving device 6 provided immediately below the article discharge position B.
The shutters are placed on the lower side in the traveling direction of the conveyor 71 installed therebelow, so that the shutters can be sequentially opened with a time lag. Therefore, when the shutter release operation signal is issued from the control device 10, each shutter is released. The articles X, X, which are temporarily held on the members 65A to 65H.
· Indicates that the items falling on the conveyor 71 on the lower side in the traveling direction of the conveyor 71 are sequentially dropped on the conveyor 71 with a time lag. The articles X, X discharged from the article discharge position B onto the conveyor 71 because the articles are sequentially moved onto the conveyor 71 and then fall onto the conveyor 71.
・ ・ No longer overlaps with each other. As described above, according to the present invention, even if a plurality of articles X, X, ... .. are not superposed on the conveyor 71, and the articles X, X are conveyed in the superposed state to the packaging machine T side (the packaging machine T side cannot be bagged). There is an effect that can be solved in advance.
