Of the container 3 into the main conveyor 30 is stopped once.

When the charging of the container 3 is stopped as described above,
In the leveling machine 15 located on the downstream side of the sub-conveyor 17, the containers 3 randomly flowing from the direction regulating machine 14 and the bag feeding machine 13 upstream thereof become full at the inlet of the leveling machine 15. Therefore, in this case, during operation of the leveling device 15, for example, the time leveling device 15 exceeding 0.5 seconds (S) is used.
When the container fullness detection sensor 26 detects that the container 3 is stagnant at the entrance of the container 3, the container 3 is discharged to the outside of the transport system of the sub-conveyor 17 by the pushing plate 25b of the external discharger 25. I have. Therefore, the container 3 is continuously and smoothly produced by each filling mechanism 10.

The bucket-type main conveyor 30 as a transport mechanism has the above-mentioned filling mechanisms 10 connected alternately on the upstream side, and detects whether metal is mixed in the container 3 on the downstream side. A metal detector 32 is arranged.

A container charging mechanism 60 for charging the liquid is provided.

A control unit 104 connected to the control unit 103 is connected to the box cleaning mechanism 50 and the container loading mechanism 60. When the box cleaning mechanism 50 is stopped due to an operation standby state or failure, the control unit 104
Since there is no input reception signal at 3, the container input mechanism 60 is controlled to be in an operation standby state.

When the container loading mechanism 60 is on standby, the container loading mechanism 60 has only two dozen boxes of buffers. Therefore, after a predetermined time has elapsed, the container stacking mechanism 40 and the main conveyor 30 are controlled to stop. Have been. When the operation of the box cleaning mechanism 50 is restarted,
By operating the operation panel 110 or the like attached to the side, the operator manually restarts.

As shown in FIG. 1 and FIG.
A box sealing mechanism 70 for sealing the top flap of the box 4 into which dozens of containers 3 have been put by the container feeding mechanism 60 by means such as bonding. The box 4 sealed by the box sealing mechanism 70 is conveyed by a conveyor 71, and the number of containers 3 in the box 4 is checked by a weight checker 72. Then, a predetermined item such as an expiration date is stamped by a stamping mechanism 73. It has become. The box 4 stamped by the stamping mechanism 73 is wrapped by a wrapping mechanism 80 and a heat tunnel mechanism 81 arranged at the end of the conveyor 71.

As shown in FIG. 7, a control section 105 connected to the control section 104 is connected to the box sealing mechanism 70. If the operation of the box closing mechanism 70 is delayed, the operation completion signal is not sent from the control unit 105 to the control unit 104, so that the box closing mechanism 50 and the container loading mechanism 60 are controlled to be in the operation standby state. I have. After the release, automatic restart is performed.

If there is not enough product in the container loading mechanism 60, no control signal is sent from the control unit 104 to the control unit 105, so that the box sealing mechanism 70 is controlled to be in the operation standby state. I have.

Further, when the wrapping mechanism 80 continues to be stopped, the flow of the outlet to the marking mechanism 73 deteriorates, and the outlet fullness detection sensor 74 as a detection unit connected to the central control unit 100 operates. The box closing mechanism 50, the container loading mechanism 60, and the box closing mechanism 70 are controlled so as to be in an operation standby state. After the release, it will be restarted automatically.

As shown in FIGS. 1 and 8, the box 4 wrapped by the wrapping mechanism 80 and the heat tunnel mechanism 81 is switched from single-row conveyance to double-row conveyance by the two-row transfer mechanism 90, and the conveyor 91 is moved. The paper is then transported to the box stacking mechanism 92. The box stacking mechanism 92 cuts out a total of 6 boxes of 2 rows × 3 pieces in total, and the total of 6 boxes 4 cut out by the box stacking mechanism 92 is a larger carton box by the box packing mechanism 93. Packed in 5. The box 5 packed by the box packing mechanism 93 is a paper sealing mechanism 9.
After being sealed by the number 4, the number of products is confirmed by the weight checker 95. After the number of products is confirmed by the weight checker 95, predetermined items such as the expiration date are stamped by the stamping mechanism 96.

As shown in FIG. 8, a control unit 106 connected to the central control unit 100 is connected to the wrapping mechanism 80, and a control unit connected to the central control unit 100 is connected to the box packing mechanism 93. The unit 107 is connected. And
When the operation standby state of the two-row transfer mechanism 90 continues, the flow of the outlet with respect to the wrapping mechanism 80 deteriorates. As a result, the exit fullness detection sensor 97 is operated to control the wrapping mechanism 80 to stop. After the release, the restart is manually performed by operating the operation panel 110.

When the flow at the outlet of the two-row transfer mechanism 90 is deteriorated due to the occurrence of an abnormality in the packing mechanism 93 or the like, the outlet fullness detection sensor 98 is activated. As a result, the two-row transfer mechanism 90 is in the operation standby state, and is automatically restarted after being released. It should be noted that when an abnormality occurs in the box packing mechanism 93, the box stacking mechanism 92 also waits for operation.

The sealing mechanism 94 is provided with a sensor for detecting an overload of the motor for transporting the box 5 and a sensor (not shown) for detecting a shortage of the tape for sealing. It is designed to issue an alarm. When the flow of the outlet with respect to the box packing mechanism 93 is deteriorated when an abnormality occurs in the paper sealing mechanism 94, the outlet fullness detection sensor 99 is operated to control the box packing mechanism 93 to the operation standby state via the control unit 107. It has become. After the release, it will be restarted automatically.

As described above, the central control unit 100 and the control units 101 to 107 control the mechanisms 10 to 90, 92
The operation status of each of the mechanisms 10 to 90, 92 to 94 is stopped, restarted, and bypass operation is controlled to an optimum state in accordance with the entire flow.

Next, the entire flow from the filling of the candy 2 of the work filling and packaging apparatus 1 to the packaging in the box 5 will be described. The candy 2 stored in the stocker 11 of each filling mechanism 10 is a counter 1
The number is counted to a predetermined number at 2, and the bag-like container 13 fills and seals the bag-like container. The direction of the container 3 discharged from the bag feeding machine 13 is reversed in each of the filling mechanisms 10 provided with the direction regulating machines 14 so as to match the direction of each of the filling mechanisms 10 without the direction regulating machines 14. Then, the candy 2 in the container 3 is transported to the main conveyor 30 by the sub-conveyor 17 in a state where the posture of the candy 2 in the container 3 is adjusted as shown in FIG.

In the leveling machine 15 on the downstream side of the sub-conveyor 17, when the containers 3 randomly flowing from the bag feeding machine 13 become full at the entrance of the leveling machine 15, this state is detected by an entrance full sensor 26. Is detected by the pusher plate 25b of the external discharger 25 and the container 3
Is discharged. Thereby, the container 3 is continuously and smoothly produced by each filling mechanism 10.

Next, when the container 3 is conveyed to the merger 16 by the sub-conveyor 17, the container 3 is stored on the sub-conveyor 17 by hitting the descending stopper 22 of the discharger 20. When the product position detection sensor 19 detects that the container 3 is present at the end of the sub-conveyor 17 and the loading timing proximity sensor 31 detects that the bucket position of the main conveyor 30 has reached the optimal position for loading, the merging machine The 16 extruding plates 16b connect the container 3 to the main conveyor 3
0, and merges with the container 3 from another filling mechanism 10 on the main conveyor 30. Thereby, one container 30 is placed in each bucket of the main conveyor 30.

In this manner, the containers 3 are placed on the main conveyor 30 at predetermined intervals, but the container stacking mechanism 40, the container loading mechanism 60, etc., which are located downstream of the entire apparatus, are stopped. As shown in FIG. 4, when the main conveyor 30 is stopped, the stopper 22 of the discharger 20 as a bypass mechanism is raised, and the sub-conveyor 17 is stopped.
The transported container 3 is stored in the primary stock box 24 via the chute 23. Thereby, the container 3 is continuously and smoothly produced by each filling mechanism 10.

Next, a predetermined number of containers 3 conveyed by the main conveyor 30 to a position short of the container stacking mechanism 40.
The metal detector 32 checks whether or not metal is mixed in the container 3 and is transported to the container stacking mechanism 40.

Next, in the container stacking mechanism 40, the containers 3 conveyed by the main conveyor 30 are stored in the storage sections 41a of the rotary table 41 by the stacking means 42 in a quantity of a dozen units. Then, the containers 3 are put into the boxes cleaned by the box cleaning mechanism 50 by the container loading mechanism 60 in a quantity of a dozen units.

When the box cleaning mechanism 50 is stopped due to an operation standby state or failure, the container loading mechanism 60 is in an operation standby state. During standby of the container loading mechanism 60, since the container loading mechanism 60 has only two dozen boxes of buffers, the container accumulation mechanism 40 and the main conveyor 30 stop after a predetermined time has elapsed. When the operator manually restarts the operation of the box cleaning mechanism 50 by operating the operation panel 110 or the like, the container stacking mechanism 40, the main conveyor 30 and the like are automatically activated.

Next, when the box 4 in which a dozen units of the containers 3 have been loaded by the container loading mechanism 60 is conveyed to the box closing mechanism 70 via the conveyor 43, the box closing mechanism 7
0, the top flap of the box 4 is sealed by means such as bonding. If the operation of the box closing mechanism 70 is delayed, the box closing mechanism 50 enters an operation standby state. Also, the container input mechanism 60
When the product is insufficient, the box sealing mechanism 70 enters an operation standby state.

Next, the box 4 sealed by the box sealing mechanism 70 is conveyed by the conveyor 71 and the number of containers 3 in the box 4 is checked by the weight checker 72. Is stamped. The box 4 stamped by the stamping mechanism 73 is wrapped by a wrapping mechanism 80 and a heat tunnel mechanism 81 arranged at the end of the conveyor 71. If the stop state of the wrapping mechanism 80 continues, the flow of the outlet with respect to the stamping mechanism 73 deteriorates, and the outlet fullness detection sensor 74 operates. Thereby, the box closing mechanism 70 and the box closing mechanism 50 are in an operation standby state.

Next, the boxes 4 wrapped by the wrapping mechanism 80 and the heat tunnel mechanism 81 are switched from single-row conveyance to double-row conveyance by the two-row transfer mechanism 90 and passed through the conveyor 91 to the box stacking mechanism 92. Conveyed. A total of six boxes 4 cut out by the box stacking mechanism 92
Are packed in a larger carton box 5 by a box packing mechanism 93.

When the operation of the two-row transfer mechanism 90 in the operation standby state continues and the flow of the outlet with respect to the wrapping mechanism 80 deteriorates, the outlet fullness detection sensor 97 is activated, and the wrapping mechanism 80 is stopped. Further, when the flow at the outlet of the two-row transfer mechanism 90 is deteriorated due to the occurrence of an abnormality in the box packing mechanism 93 or the like, the outlet fullness detection sensor 98 is activated. As a result, the two-row transfer mechanism 90 enters an operation standby state.

Next, the number of products is checked by the weight checker 95 after the box 5 packed by the box packing mechanism 93 is sealed by the paper sealing mechanism 94. After the number of products is confirmed by the weight checker 95, predetermined items such as an expiration date are stamped by the stamping mechanism 96, and a series of operations is completed.

As described above, the mechanisms 10 to 90, 92
The operation status of the central control unit 100 and each control unit 10
Since monitoring is performed by 1 to 107, when a trouble occurs, the stop, restart, bypass operation, and the like of each of the mechanisms 10 to 90 and 92 to 94 are controlled to an optimum state according to the overall flow. As a result, the operation time from the filling of the candy 2 into the container to the packaging in the box is greatly reduced, and the operation efficiency is further improved.
