Description

  The present invention relates to a packaging system in which two intermittently rotating bag filling and packaging machines are arranged adjacent to each other.

The intermittent rotary bagging and packaging machine holds both side edges of the bag with a pair of left and right grippers, intermittently transports the bag at an equal angle along the circular transfer path, and opens the bag mouth in the transfer process, The packaging process including the filling of the product, the sealing of the bag mouth and the removal of the product bag is sequentially performed. In response to this packaging process, the intermittently rotating bagging and packaging machine has a plurality of pairs of left and right grippers arranged around it and intermittently rotates to move the grippers intermittently at equal angles along a circular movement path. Rotary table, various packaging processing devices, that is, an empty bag supply device for supplying empty bags to the gripper, a bag opening device for opening a bag mouth of a bag held by the gripper, and a packaged item in a bag held by the gripper A package filling device for filling a bag, a bag mouth sealing device for sealing a bag mouth of a bag held by the gripper, and a product bag taking out device for receiving the sealed product bag from the gripper and taking it out of the transfer path. . Each of these packaging processing apparatuses is arranged in the vicinity of a stop position on the gripper moving path, and sequentially executes each of the packaging processing steps.
In addition, in the intermittent rotation type bag filling and packaging machine, the bag is held in a vertical posture with a pair of left and right grippers (see Patent Document 1) and the bag is held in a horizontal posture with a pair of left and right grippers. (See Patent Document 2).

The intermittent rotary bagging and packaging machine has the following advantages.
(1) Since each said packaging process process is performed with respect to the gripper stopped on the said movement path | route, or the bag stopped on the said transfer path | route, a packaging process can be performed reliably and stably.
(2) Since there is no need to provide a follow-up mechanism or a synchronization mechanism in each packaging processing apparatus as in the case of a continuous transfer type bag filling and packaging machine (see Patent Document 3), the structure of each packaging processing apparatus and the entire packaging machine is simplified. Therefore, it is possible to reduce the size and cost.
(3) Since the bag is generally transferred in the bag width direction on the circular transfer path, the intermittent transfer type bagging and packaging machine in which the bag is transferred in the thickness direction of the bag along the linear transfer path (Patent Document) 4)), the bag swaying accompanying the transfer is small, and various problems caused by the bag swaying, for example, a bag that has become heavier due to filling the package, falls down from the original holding position of the gripper. The problem that the liquid filled in the bag jumps out of the bag or adheres to the planned sealing portion on the inner surface of the bag mouth is less likely to occur.

(4) Since each packaging processing apparatus can be arranged around the rotary table, that is, in the vicinity of the outer peripheral edge of the packaging machine, it is possible to easily replace and adjust parts in accordance with the type change. For this reason, the intermittent rotary bagging and packaging machine is highly versatile and can be easily maintained and cleaned. On the other hand, in the intermittent transfer type bag filling and packaging machine (see Patent Document 4), since the packaging processing device is arranged near the center of the packaging machine, it is relatively difficult to replace, adjust, maintain, and clean the parts. is there.
(5) In the intermittent transfer type bagging and packaging machine (see Patent Document 4), the packaging process cannot be performed at the return part of the chain conveyor, but the intermittent rotation type bagging and packaging machine has a circular bag transfer path. Almost all of the transfer path can be effectively used for the packaging process, and a space-saving and efficient packaging process can be performed.

  The intermittent rotary bagging and packaging machine has the above-mentioned advantages, but due to its structure, there is a limit to speeding up, and the processing capability is inferior to that of the continuous transfer bagging and packaging machine. Moreover, since the intermittent rotation type bagging and packaging machine transfers the bag in the bag width direction, the transfer distance of one time (as compared to the intermittent transfer type bagging and packaging machine (see Patent Document 4) for transferring the bag in the thickness direction) The transfer distance between the intermittent stop positions) is long, and the processing capacity is inferior even compared to the intermittent transfer type bagging and packaging machine. Therefore, in order to improve the processing capacity while taking advantage of the intermittent rotary bagging and packaging machine, simultaneously supplying a plurality of empty bags to a plurality of pairs of grippers of the rotary table, and transferring the plurality of bags, There has been proposed a multiple-type intermittent rotary bagging and packaging machine (see Patent Documents 5 and 6) in which the same packaging process is simultaneously performed on the plurality of bags at the stop position.

  However, the intermittent rotation type bag filling and packaging machine of the multiple type inevitably increases the diameter of the rotary table, that is, the diameter of the bag transfer path, and the transfer distance between the intermittent stop positions also increases. If the speed is the same, the bag transfer speed and the acceleration / deceleration speed are increased as compared with a general single bag type intermittent rotation type bag filling and packaging machine. As a result, the swaying of the bag accompanying the intermittent transfer becomes large, and various problems (see (3) above) due to this swaying may occur. For this reason, in the multiple-type intermittent rotary bagging and packaging machine, the rotational speed of the rotary table has to be slow compared to the single-bag type intermittent rotary bagging and packaging machine. There is a problem that it cannot be improved. Therefore, the multiple-type intermittent rotary bagging and packaging machine is designed so that the width of the supplied bag is limited to a relatively small width and the diameter of the rotary table is designed not to be too large, thereby improving the processing capacity. Realized.

On the other hand, in order to improve the processing capability while taking advantage of the intermittent rotary bagging and packaging machine, a plurality of intermittent rotary bagging and packaging machines have been conventionally installed (see Patent Document 7). However, when installing multiple intermittently rotating bagging and packaging machines, a large installation space is required at present, and an operator (mainly for refilling empty bags) must be placed in each packaging machine. is there. In addition, it is necessary to install a drive source for each intermittent rotation type bag filling and packaging machine. Also, when product bags transported from individual intermittent rotation type bag filling and packaging machines are merged, a dedicated device is installed for that purpose. This complicates the product bag unloading line.
The present invention has been made in view of the present situation of the intermittent rotary bagging and packaging machine as described above, and in the case of improving the processing capacity by installing two intermittent rotary bagging and packaging machines, The purpose of the present invention is to provide a packaging system that can save space and labor in comparison with, and can simplify the carry-out line for product bags in both packaging machines.

  The present invention holds both side edges of a bag with a pair of left and right grippers, intermittently conveys the bag at an equal angle along a circular transfer path, and opens the bag mouth, fills the package, Two intermittent rotary bagging and packaging machines that sequentially perform the same packaging process including mouth sealing and product bag removal are arranged adjacent to each other, and each intermittent rotary bagging and packaging machine has multiple pairs of left and right grippers around it. A rotary table that is arranged in pairs and intermittently rotates to intermittently move the gripper along the circular movement path at equal angles, an empty bag supply device that supplies an empty bag to the gripper, and a bag mouth of a bag held by the gripper A bag mouth opening device for opening a bag, a bag filling device for filling a bag held in the gripper with a material to be packaged, a bag mouth sealing device for sealing the bag mouth of the bag held by the gripper, and after sealing A product bag take-out device for receiving a product bag from the gripper and taking it out of the transfer path, the empty bag supply device, the bag mouth opening device, the package filling device, the bag mouth sealing device, and the product bag take-out device; The present invention relates to a packaging system arranged near the stop position on the movement path of In this packaging system, two rotary tables are arranged adjacent to each other on a common machine base, connected to a common drive source, and intermittently rotated in opposite directions in the same intermittent indexing mode, corresponding to each rotary table. An empty bag supply device, a bag mouth opening device, an article filling device, a bag mouth sealing device, and a product bag takeout device are arranged on the machine base, and among these, the empty bag supply device and the product bag takeout device are both rotary. Of the stop positions of the grippers disposed on the table, the grippers are disposed adjacent to each other in the vicinity of the stop positions closest to each other or the stop positions before and after the stop positions. The same intermittent indexing mode means that in the intermittent indexing movement of the rotary table, the time of one cycle of movement and stop, the distribution of the movement time and stop time in one cycle, and the indexing angle are the same. means.

The packaging system according to the present invention can take, for example, the following embodiments.
(1) The intermittent rotation stoppage and rotation timing of the two rotary tables are set almost opposite to each other.
(2) In the case of (1), a common carry-out conveyor is installed in the two intermittently rotating bag filling and packaging machines, and each product bag take-out device alternately discharges the product bags.
(3) In the two intermittently rotating bag filling and packaging machines, the empty bag supply device, the bag mouth opening device, the packing material filling device, the bag mouth sealing device, and the product bag takeout device are the rotary shafts of the two rotary tables. Are arranged in a line-symmetric position with a line perpendicular to the line connecting the lines as symmetry axes.
(4) Two pairs of grippers arranged on each rotary table are a pair of double type, and the two pairs of grippers of the same set each have a holding surface when holding a bag arranged on substantially the same plane. In the process of intermittently moving the two bags held by the two pairs of grippers in the same set along the movement path, the packaging process is simultaneously performed on the two bags.
(5) The bag held by the gripper is in a vertical posture with the bag mouth facing upward.

The packaging system according to the present invention rotates two rotary tables in the opposite direction, and sets each two empty bag supply devices and product bag take-out devices between two rotary tables on a common machine table. Adjacent to each other. With this arrangement structure, the interval between the two rotary tables can be narrowed to save the space of the entire packaging system.
In addition, this arrangement structure makes it possible to align the supply direction of empty bags to two adjacent empty bag supply devices in one direction, so that the burden on the operator for replenishing empty bags to the empty bag supply device is great. As a result, a single operator can take charge of the operation and management of the entire packaging system (two intermittently rotating bagging and packaging machines). Furthermore, since the two product take-out devices are arranged adjacent to each other, the product bags taken out from the two intermittent rotary bag filling and packaging machines can be collected in one place. For this reason, the product bag transport line for transporting product bags in the subsequent process can be shared and simplified by the two intermittently rotating bag filling and packaging machines, which leads to space saving.

It is a top view which shows an example of the packaging system which concerns on this invention. It is a top view which shows the other example of the packaging system which concerns on this invention. It is a top view which shows the further another example of the packaging system which concerns on this invention.

Hereinafter, with reference to FIGS. 1-3, the packaging system which concerns on this invention is demonstrated concretely.
The packaging system shown in FIG. 1 includes two intermittently rotating bagging and packaging machines 2 and 3 installed adjacent to each other on a common machine base 1. Each intermittently rotating bagging and packaging machine 2, 3 has a plurality of pairs (8 × 2 sets) of a pair of left and right grippers 4 arranged around it, intermittently rotating and intermittently gripping the grippers 4 at equal angles along a circular movement path. Rotary tables 5 and 6 to be moved are provided. In the rotary tables 5 and 6, the diameter of the moving path of the gripper 4 is set to be the same.
The intermittent rotary bagging and packaging machines 2 and 3 simultaneously supply two empty bags to the two pairs of grippers of the rotary tables 5 and 6 and transfer the two bags along a predetermined transfer path. However, it is a double-type intermittent rotation type bag filling and packaging machine (see Patent Document 5) in which various packaging processes are simultaneously performed on the two bags at each stop position.

A drive motor (not shown) that is a common drive source for rotating the rotary tables 5 and 6 is installed in the machine base 1. The driving force of the driving motor is transmitted to the index devices of the rotary tables 5 and 6 through a reduction gear (not shown) and further transmitted to the rotary tables 5 and 6. For example, the driving force can be individually transmitted to or cut off from the index devices of the rotary tables 5 and 6 via a clutch.
The intermittent indexing modes (time for one cycle of movement and stop, distribution of movement time and stop time in one cycle, and index angle) of the rotary tables 5 and 6 are set to be the same by the index device. The rotary tables 5 and 6 are intermittently rotated in opposite directions (the rotary table 5 is counterclockwise and the rotary table 6 is clockwise), and the timings of movement and stop are set almost opposite to each other. In FIG. 1, the rotary table 5 is stopped and the rotary table 6 is moving. In this manner, the load applied to the drive source is averaged by setting the movement and stop timings of the rotary tables 5 and 6 almost opposite to each other (shifting the movement and stop timings by 1/2 cycle). Thus, the drive source can be made compact and the durability can be improved without reducing the processing capacity of the packaging system.

The rotary tables 5 and 6 stop eight times at equal angular intervals during one rotation. The position at which the moving path of the gripper 4 of the rotary table 5 and the moving path of the gripper 4 of the rotary table 6 are closest is selected as one of the stop positions (stop positions H, h) of the gripper 4 on the moving path. The other seven stop positions (A to G, a to g) are set on the moving path at an angular interval of 45 ° from the stop position.
Out of the stop positions A to H and the stop positions a to h, product bag take-out devices 8 and 9 for taking the product bag 7A out of the transfer path are adjacent on the machine base 1 in the vicinity of the stop positions H and h closest to each other. An empty bag supply device 10 that is disposed and supplies a bag 7 (sometimes referred to as an empty bag 7) to the gripper 4 on the machine base 1 in the vicinity of the next stop position A, a (on the front side in the rotational direction), 11 are arranged adjacent to each other.

In addition, on the machine table 1 around the rotary tables 5 and 6, bag height detection devices 12 and 13 for detecting the height of the bag 7 held by the gripper 4 in the vicinity of the stop positions B and b, stop In the vicinity of the positions C and c, the bag mouth opening devices 14 and 15 for opening the bag mouth of the bag 7 held by the gripper 4, and in the vicinity of the stop positions D and d, an article to be packaged (solid matter) is placed in the bag 7. In the vicinity of the to-be-packaged filling devices 16 and 17 and the stop positions E and e, in the vicinity of the to-be-packaged filling devices 18 and 19 and the stop positions F and f for filling the bag 7 with the to-be-packaged (liquid material). In addition, steam deaerators 20 and 21 for blowing steam into the bag 7 to deaerate the inside of the bag, and ultrasonic sealing devices 22 and 23 for sealing the bag mouth of the bag 7 are disposed in the vicinity of the stop positions G and g. ing.
Product bag take-out devices 8 and 9, Empty bag supply devices 10 and 11, Bag height detection devices 12 and 13, Bag opening devices 14 and 15, Package filling devices 16 and 17, Package filling devices 18 and 19 The steam degassing devices 20 and 21, and the ultrasonic sealing devices 22 and 23 are arranged at substantially line-symmetrical positions with a line Z perpendicular to the line connecting the rotation axes (X, Y) of the rotary tables 5 and 6, respectively. Has been.
The drive source for intermittently rotating the rotary tables 5 and 6 is also a drive source for operating the various packaging processing devices mentioned above. As with the rotary tables 5 and 6, the driving force to the various packaging processing devices is transmitted or cut off by the clutch.

  Further, on the machine base 1, a quadruple-type conveyor magazine type empty bag supply device 24 is arranged in front of the adjacent empty bag supply devices 10 and 11, and the rear end is outside the device (front side). It extends. A product bag discharge conveyor 25 is disposed at the lower central portion of the adjacent product bag take-out devices 8 and 9, and the tip extends outward (the other side). Both the conveyor magazine type empty bag supply device 24 and the product bag discharge conveyor 25 are common to the intermittent rotation type bag filling and packaging machines 2 and 3, and only one each is required. The conveyor magazine type empty bag supply device 24 includes four conveyors 24a to 24d arranged in parallel on the left and right, and two empty bags 7 in total from the two right conveyors 24a and 24b. And a total of two empty bags 7 are simultaneously supplied to the empty bag supply device 11 from the two left-hand conveyors 24c and 24d. The product carry-out conveyor 25 receives the product bags 7A that the product bag take-out devices 8 and 9 alternately discharge two by two, and carries them out for a subsequent process (for example, disinfection or boxing). The conveyance direction of the bag 7 on the conveyor magazine type empty bag supply device 24 and the unloading direction of the product bag 7A on the product bag unloading conveyor 25 are the same, and the direction perpendicular to the line connecting the rotation axes of the rotary tables 5 and 6 (see FIG. 1 from the near side to the other side).

Next, each packaging processing step sequentially performed by the intermittent rotary bagging and packaging machines 2 and 3 will be described.
(1) The empty bag 7 positioned at the tip of the conveyor magazine type empty bag supply device 24 is sucked by a suction cup (not shown) and taken up from the conveyors 24a to 24d, and converted into a vertical posture with the bag mouth facing up. (This vertically oriented bag is indicated by 7a in FIG. 1). Subsequently, a gripper (not shown) of the empty bag supply devices 10 and 11 holds the empty bag 7 (7a), changes the direction of the predetermined angle while transferring the empty bag 7 in a horizontal plane, and stops at the stop positions A and a. 4 (refer to the supply device described in Japanese Patent No. 3123709, the packaging bag supply device S described in Japanese Patent No. 5044484). The chuck member of the empty bag supply device 10 and the chuck member of the empty bag supply device 11 operate in opposite directions (axisymmetric).

Supply of the bag 7 to the gripper 4 of the intermittent rotary bagging and packaging machine 2 by the empty bag supply device 10 (two sheets at the same time), and the bag to the gripper 4 of the intermittent rotation bagging and packaging machine 3 by the empty bag supply device 11 The supply of 7 (two sheets at the same time) is performed alternately.
Since the supply of the bags 7 to the two intermittently rotating bag filling and packaging machines 2 and 3 (empty bag supply devices 10 and 11) can be performed by one conveyor magazine type empty bag supply device 24, The packaging system can be made compact and space-saving, and the operator can easily refill empty bags on the conveyors 24a to 24d. Moreover, since two conveyor magazine type empty bag supply devices are not required, the entire packaging system can be simplified and the space can be saved.

(2) At the stop positions B and b, the bag height detection devices 12 and 13 perform the height inspection of the bag 7 held by the gripper 4, and the inspection result is transmitted to a control device (not shown). When the height of the bag 7 deviates from the reference height by a predetermined value or more, the control device determines that the bag 7 is a defective bag, and does not perform each packaging process on the bag 7 at the subsequent stop position. For example, the gripper 4 is opened at the stop positions G and g, and the bag 7 is discharged out of the machine through a chute or the like. Alternatively, after each packaging process is performed on the bag 7 at the subsequent stop position, the ultrasonic horn and anvil (not shown) of the ultrasonic sealing devices 22 and 23 are provided corresponding to the deviation from the reference height. It is also possible to control to adjust the height position).
(3) At the stop positions C and c, the bag mouth of the bag 7 held by the gripper 4 is opened by the bag mouth opening devices 14 and 15.
(4) At the stop positions D and d, the packaging material (solid matter) is filled into the bag 7 held by the gripper 4 by the packaging material filling devices 16 and 17.

(5) At the stop positions E and e, the packaging material filling devices 18 and 19 fill the packaging material (liquid material) into the bag 7 held by the gripper 4.
(6) At the stop positions F and f, steam is blown into the bag 7 held by the gripper 4 by the steam deaerators 20 and 21, and the bag is deaerated.
(7) At the stop positions G and g, the bag mouth of the bag 7 held by the gripper 4 is sealed by the ultrasonic sealing devices 22 and 23.

(8) At the stop positions H and h, the product bag 7A held by the gripper 4 is sandwiched by chuck members (not shown) of the product bag take-out devices 8 and 9, and after the gripper 4 is opened, the product bag 7A is placed in a horizontal plane. The product bag 7A is released when it reaches the product bag carrying conveyor 25. The product bag 7A turns 90 ° in the horizontal plane while being transferred. The product bag take-out devices 8 and 9 are basically the same devices as the empty bag supply devices 10 and 11. The chuck member of the product bag take-out device 8 and the chuck member of the product bag take-out device 9 operate in opposite directions (in line symmetry).
The timing at which the gripper 4 of the rotary table 5 stops at the stop position H and the timing at which the gripper 4 of the rotary table 6 stops at the stop position h are shifted by 1/2 cycle. 7A is taken out alternately. Accordingly, the product bags 7A are carried out of the machine by the product bag carry-out conveyor 25 in a state of being aligned in two rows, and sent to the next process (disinfection, boxing, etc.).
Since the product bag take-out devices 8 and 9 are disposed adjacent to each other and the product bag 7A is discharged onto the common product bag carry-out conveyor 25, the product bag carrying line is simplified and space saving can be achieved.

The packaging system shown in FIG. 2 makes the movement and stop timings of the rotary tables 5 and 6 coincide with each other, and instead of the product take-out devices 8 and 9 as a product take-out device, a general chute (not shown) Unlike the packaging system shown in FIG. 1, it is substantially the same as the packaging system shown in FIG. 1 in that the product discharge sheet 14 described below is disposed adjacent to the stop positions H and h. . In FIG. 2, the same reference numerals are assigned to substantially the same parts as the parts of the packaging system shown in FIG.
In the packaging system shown in FIG. 2, a total of four product bags 7A are released simultaneously from the grippers 4 stopped at the stop positions H and h, and dropped onto the product bag carry-out conveyor 25 through the chute, Product bags 7A are carried out of the machine in a state of being arranged in two rows, and sent to the next process (disinfection, boxing, etc.). In this packaging system, the direction of the product bag 7A conveyed on the product bag carry-out conveyor 25 is 90 ° different from the direction of conveyance in the packaging system shown in FIG. 1, and the product bag 7A is conveyed in its width direction. The

The packaging system shown in FIG. 3 has the same timing as the movement of the rotary tables 5 and 6 and the timing of the rotary tables 5 and 6 is slightly increased, and the width of the product bag carry-out conveyor 25 is increased. 1 is substantially the same as the packaging system shown in FIG. 1 in other respects. In FIG. 3, the same reference numerals are assigned to substantially the same parts as the parts of the packaging system shown in FIG.
In the packaging system shown in FIG. 3, two product bags 7A held by the gripper 4 stopped at the stop position H are sandwiched between chuck members (not shown) of the product bag take-out device 8 and simultaneously stopped at the stop position h. The two product bags 7A held by the gripper 4 are clamped by a chuck member (not shown) of the product bag take-out device 9, and after the gripper 4 is opened, the product bag 7A is transferred in a horizontal plane, and the product bag carrying conveyor 25 When reaching the top, the product bag 7A is released. The four product bags 7A were turned 90 ° in the horizontal plane while being transferred, arranged in a line in the bag width direction on the product bag carry-out conveyor 25, and held between the chuck members of the product bag take-out device 8 2 The individual product bags 7A fall from the center of the product bag carry-out conveyor 25 to the right side, and the two product bags 7A sandwiched between the chuck members of the product bag take-out device 9 fall simultaneously from the center of the product bag carry-out conveyor 25 to the left side. To do. Accordingly, the product bags 7A are carried out of the machine by the product bag carry-out conveyor 25 in a state of being arranged in four rows, and sent to the next process (disinfection, boxing, etc.).

In the packaging system described above, the two intermittently rotating bagging and packaging machines 2 and 3 are operated together, but only one of them can be operated.
Further, in the packaging system described above, the intermittent rotation type bag filling and packaging machine is a type that holds the bag in a vertical posture with the bag mouth facing upward by a pair of left and right grippers. The present invention can also be applied to a type in which a bag is held in a horizontal posture by a gripper (see Patent Document 2).
