A pusher member 92 is provided to return to the receiving position A of the portion 32.
[0035]
Further, as shown by an arrow b from the carry-in conveyor 31 between the side opposite to the carry-in side of the small bag X at the upstream end of the carrying unit 32, that is, between the carrying unit 32 and the storage unit 33, the second article in the figure. A stopper member 93 that receives the small bag X supplied on the partition member 72 of the holding member 71 is provided so as to be movable between a receiving position indicated by a solid line and a retracted position indicated by a chain line. That is, the cylinder 95 supported by the bracket 94 attached to the main body frame 30a is rotated in the direction of the arrow j about the support shaft 96 as the rod 95a advances and retreats at the tip of the rod 95a. The stopper member 93 is fixed.
[0036]
Further, it moves up and down between a position shown by a solid line and a position shown by a thick chain line by a driving means (not shown) to a position slightly ahead of the second photoelectric sensor 58b, and when it moves up, it returns from the storage section 33 to the transport section 32. A shutter member 97 is provided to receive the small bag X and to carry the small bag X into the transport section 32 from the direction of the arrow b when it moves downward (see FIG. 7).
[0037]
A control system of the bag-packed product production line 1 is shown in FIG. The control system is provided with a control unit 100 that comprehensively controls the production line 1 and stores initial settings and various control parameters for each type of pouch X. The control unit 100 is connected to the packaging machine 10, the seal checker 20, the carry-in conveyor 31, the transport unit 32, the storage unit 33, the discharge unit 81, the bagging device 40, the pusher member 92, the stopper member 93, the shutter member 97, and the like. A control signal is output to control these drivings, and detection signals from the first and second photoelectric sensors 58a and 58b are input.
[0038]
Next, operation | movement of the bagging goods production line 1 is demonstrated.
[0039]
First, the basic operation will be described. The sachets X from the packaging machine 10 via the seal checker 20 are carried one by one from the carry-in conveyor 31 of the carrying device 30 to the carrying unit 32 in a lateral posture.
[0040]
For example, if the small bag X is carried into the second article holding member 71 that moves in the receiving position a, in this case, the second article holding member 71 includes the partition members 72 provided in the holding member 71. 72 partition surfaces 72a... 72a are once in a substantially horizontal state one by one by the intermittent travel of the pair of chains 65a and 65d that support the holding member 71, that is, the interval between adjacent partition members 72 and 72. Moving. Then, for example, based on the detection signal of the small bag X by the second photoelectric sensor 58b so that the small bag X is loaded onto the partition surface 72a from the carry-in conveyor 31 when each of the partition surfaces 72a. The travel of the chains 65a and 65d is controlled. In addition, normally, since the shutter member 97 is in the downward movement position and the stopper member 93 is in the receiving position, the carried pouch X is reliably received on the partition surface 72a by the stopper member 93, and the adjacent partition member It is held well in the holding space between 72 and 72.
[0041]
Next, the chains 65a and 65d travel after one pitch and then stop, and the next small bag X is carried onto the partition surface 72a, which is almost horizontal at that time. The above operations are repeated until the twelve small bags X ... X are held by the second article holding member 71. The loaded pouch X is changed from the horizontal posture to the vertical posture as the chains 65a and 65d travel, and the vertical posture is maintained until the discharge position a is reached.
[0042]
Further, the first article holding member 70 on the front side in the example holding the twelve sachets X is stopped at the discharge position a. The first article holding members 70 from which all of the small bags X ... X held by the discharging operation of the discharging unit 81 are discharged to the bagging device 40 side move at a high speed toward the receiving position A, while the predetermined 12 The second article holding member 71 into which the small bags X... X are carried moves at a high speed toward the discharge position A while holding the small bags X. The first article holding member 70 that has reached the receiving position A is loaded with the small bags X... X from the carry-in conveyor 31, while all the small bags X. Is discharged to the bagging device 40 by the discharge portion 81. By executing such an operation without interruption, high-speed processing of the sachets X ... X is realized.
[0043]
In addition, the transport device 30 according to the present embodiment has the following characteristics. About the control which the control unit 100 performs when operation | movement of the conveyance part 32 or the downstream bagging apparatus 40 stops for some reason, it demonstrates using FIG. As an example, a case will be described in which a small bag X... X is carried into the second article holding member 71 at the receiving position a.
[0044]
First, the control unit 100 determines whether or not a retraction request signal for the stopper member 93 is input in step S1. For example, when an operation stop signal of the transport unit 32, the bagging device 40, or the like is input, the evacuation request inputs an intentional storage request signal to the outside of the machine for the small bag X ... X by the operator of the production line 1. Or when the first and second article holding members 70 and 71 collide with each other.
[0045]
If NO is determined in step S1, it is determined in step S2 whether or not the second photoelectric sensor 58b has detected the pouch X. If NO is determined, the process returns to step S1, while if YES is determined, in step S3. Waiting for the elapse of a predetermined time, that is, after reliably receiving the pouch X from the carry-in conveyor 31, the second article holding member 71 is moved by one pitch in step S <b> 4 to wait for the next pouch X to be carried.
[0046]
Next, in step S5, waiting for the reception of the twelve sachets X ... X in the second article holding member 71 is completed, the process proceeds to step S6, and the second article holding member 71 is moved to the discharge position a. And after moving the other 1st article holding member 70 which discharge of small bag X ... X was completed at Step S7 to receiving position a, it returns to Step S1.
[0047]
On the other hand, if YES is determined in step S1, the stopper member 93 is received from the receiving position and moved to the retracted position in step S8, and air is injected from the air nozzle 57, so that the partition member 72 of the second article holding member 71 is ejected. The supplied sachet X is further sent to the front storage part 33.
[0048]
Next, in step S9, the storage unit 33 is moved forward by one pitch, and after waiting for the next storage of the small bag X in the storage unit 33, whether or not a retraction request release signal for the stopper member 93 is input in step S10. If NO is determined, the process returns to step S8. If YES is determined, the process proceeds to step S11.
[0049]
And when it determines with the space | interval between the small bags X and X on the carrying-in conveyor 31 being more than a predetermined space | interval in step S11, the small bag X nearest to the receiving position A reaches | attains the receiving position A in step S12. After waiting, the shutter member 97 is moved up in step S13, and in step S14, the storage section 33 is moved backward by one pitch and the pusher member 92 is advanced to transfer the small bag X of the storage section 33 to the second article of the transport section 32. Return to the holding member 71. Thereafter, after the shutter member 97 is moved down in step S15, the process returns to step S11. Note that the interval between the pouches X and X is determined based on the detection signals of the first and second photoelectric sensors 58a and 58b, and the operation is performed from the storage unit 33 by using the opportunity that the interval is more than a predetermined interval. This is to return the small bag X to the transport unit 32.
[0050]
If NO is determined in step S11, this means that there is not enough time to return the pouch X of the storage unit 33 to the transport unit 32. In this case, the process proceeds to step S16. When a predetermined time elapses from the detection by the two photoelectric sensors 58b, the stopper member 93 is moved to the receiving position in step S17 and the injection of air from the air nozzle 57 is stopped, and the small bag X is transferred from the carry-in conveyor 31 to the second article holding member 71. To carry in. The predetermined time is, for example, the time required for the sachet X to move a distance that is approximately half of its length.
[0051]
In step S18, it is determined whether or not an end button for ending the process in the bag-packed product production line 1 has been turned ON. If NO is determined, the process returns to step S1, while if YES is determined, all processes are ended. To do.
[0052]
In this way, the sachets X that are normally carried into the upstream end portion of the carrying section 32 by the carry-in conveyor 31 are received by the stopper member 93, and then carried by the carrying section 32, and the downstream bagging device 40. Will be supplied.
[0053]
On the other hand, when the operation of the conveyance device 30, that is, the conveyance unit 32 and the downstream bagging device 40 is stopped, the cylinder 95 is driven to move the stopper member 93 to the retracted position, and the conveyance device 31 is loaded. The small pouch X passes through the upstream end of the transport unit 32 and is supplied to the storage unit 33 while maintaining the posture at the time of carrying in. In that case, the air sprayed from the air nozzle 57 positively sends out the small bag X carried into the second article holding member 71 to the storage unit 33. More specifically, the sachet X passes through the partition surface 72a of the partition member 72 of the second article holding member 71 in a substantially horizontal state with the help of the injected air so as to slide reliably. To reach. Therefore, even if the upstream packaging machine 10 or the like is not stopped, a situation where the sachets X ... X overflow on the conveying device 30 or the like is avoided.
[0054]
Further, when the transport device 30 or the like starts operating, the small bag X can be returned from the storage unit 33 to the transport unit 32 in a state where the posture is held by the pusher member 92. Accordingly, the sachets X returned from the storage unit 33 can be transported downstream and processed in the same manner as the sachets X carried in from the carry-in conveyor 31, for example, a temporary stop period of the upstream packaging machine 10 The processing operation of the sachets X can be continued by using the temporary expansion timing of the interval between the sachets X and X before and after the supply, and the productivity is reduced without requiring any work by the operator. Will be avoided.
[0055]
Further, since the transport unit 32 transports a predetermined number of the small bags X... X sequentially carried into the upstream end to the downstream side while maintaining the posture at the time of carrying in, the small bags X. When a packing device such as a boxing device including a bagging device 40 that packs a predetermined number of bags is provided, a reduction in workability when the packing device stops as described above is avoided. become.
[0056]
In addition, it can replace with the storage part 33 shown in FIG. 7, and can use the storage part 33 'shown in FIG. 10 as a storage part which concerns on other embodiment. In this case, the same reference numerals are used for components common to the above-described embodiment unless confusing.
[0057]
The storage portion 33 'is a vertical storage type shelf-like shape, for example, as indicated by an arrow by a pinion connected to a motor (not shown) and a rack meshed with the pinion and fixed to the storage portion 33'. It is configured to be vertically movable. The storage section 33 ′ is provided with a plurality of holding sections S... S, and the pouch X is stored in each holding section S. In addition, the pusher member 92 receives the small bag X that has passed through the conveyance unit 32 and the position of the stopper member 93 set to the retracted position, and the pusher member 92 is advanced to convey the stored small bags X ... X one by one. It can return to the part 32. By doing so, a plurality of small bags X ... X can be stored. Furthermore, by allowing the storage portion 33 'to move horizontally, the number of small bags X ... X that can be held per holding section S can be increased, and the small bags X ... X can be stored more efficiently. It becomes possible.
[0059]
In the above-described embodiment, the transport unit 32 has the two article holding members 70 and 71. However, when further high-speed processing is desired, the number of article holding members can be increased to, for example, four. .
[0060]
