  As shown in FIG. 1, a control panel 100 is provided in the frame structure FLM2. The control panel 100 is provided with control means for receiving detection signals from various sensors and driving a motor or a cylinder actuator according to a predetermined sequence.

  The operation of the boxing device 20 configured as described above will be described with reference to the flowcharts of FIGS.

  First, FIG. 7 shows processing performed by the container transport unit 22 and the container rotation unit 24. When the empty container 4 is carried into the container conveyance unit 22 by another container conveyance unit or the like (not shown), the drive motor 32 is activated and conveyed by the chain conveyor 30 toward the container rotation unit 24 (S10). When the container 4 reaches a predetermined position, a sensor (not shown) detects it, sends a signal to the control means, the drive motor 43 of the container rotating unit 24 operates, and the container 4 is moved by the chain conveyor 42 of the container rotating unit 24. The container is transferred from the container transport unit 22 to the container rotating unit 24 (S11). At this time, the container rotating unit 24 is at a rotation angle of 0 degree so that the chain conveyor 42 and the chain conveyor 30 are aligned on a straight line.

  When the container 4 reaches a predetermined position by the chain conveyor 42, a sensor (not shown) detects it and sends a signal to the control means. Then, the fluid cylinder 41 of the container rotating unit 24 is activated, the container holder 40b is rotated to hold the corners of the container 4 (S12), and then the drive motor 60 of the container rotation driving unit 50 is activated to rotate. The shaft 46 is rotated to rotate the container holding assembly 40. Thus, the container 1 is inclined and the preform 1 is transferred to the container 4 (S13). The transfer of the preform 1 will be described later. When the transfer is completed, the rotation angle of the container holding assembly 40 becomes 0 degree, the fluid cylinder 41 operates, the container holder 40b rotates in the opposite direction to release the corner of the container 4 (S14). The actual container 4 packed with the preform 1 is transferred to the container rotating unit 24 by the chain conveyor 42 in the direction opposite to that in step S11 (S15), and in the container transporting unit 22, the chain is moved in the direction opposite to that in step S12. The conveyor 30 moves in the opposite direction (S16). And the next empty container 4 is carried in to the container conveyance part 22, and step S10-S16 are repeated.

  On the other hand, FIG. 8 shows processing performed by the workpiece supply unit 26. The preform 1 is sequentially conveyed from the preform conveyor 70 of the workpiece supply unit 26, and the chute 72 is dropped. The count sensor 73 controls the signal every time the preform 1 passes through the chute 72. (S21), the control means increments the count (S22). In the control means, it is determined whether or not the count number has reached a predetermined value (S23). Until the count value reaches the predetermined value, the stopper motor 78 of the stopper 74 rotates the rollers 76 and 76 to perform the preform. 1 is separated and the preform 1 is sent to the workpiece transfer section 28.

  When the count number of the preform 1 detected by the count sensor 73 reaches a predetermined value, the stopper motor 78 of the stopper 74 stops the rotation of the rollers 76, 76 to sandwich the next preform 1 and stop the supply. (S24). This predetermined value corresponds to a number suitable for stocking with the small capacity hopper 82. At the same time, a gate open signal is sent (S25). After a predetermined time has elapsed (S26), the stopper motor 78 of the stopper 74 is driven, the rotation of the roller 76 is restarted (S27), the count value is initialized to 0 (S20), and the steps are repeated.

  FIG. 9 shows processing performed by the workpiece transfer unit 28. When the gate open signal is sent, the swing chute 80 is swung to the uppermost position indicated by the phantom line in FIG. 4 (S31). Then, the fluid cylinder 83 is operated to open the slide gate 82a of the small capacity hopper 82 (S32), and the preform 1 accumulated in the small capacity hopper 82 is taken out and moved to the conveyor 84. At this time, since the swing chute 80 is at the uppermost position, the preform 1 from the workpiece supply unit 26 does not fall on the small capacity hopper 82 in the state where the slide gate 82a is opened, but on the swing chute 80. Accumulate. Thus, when the slide 1 is opened to the swing chute 80 when the slide gate 82a of the small capacity hopper 82 is opened, when the preform 1 is continuously supplied from the workpiece supply unit 26, The time for stopping the supply of the preform 1 by the stopper 74 in step S26 of FIG. 8 can be shortened. Therefore, when the supply of the preform 1 is stopped by the stopper 74, the preform 1 stays and is pressed and can be prevented from being scratched due to friction with the conveyor chain.

  Then, after the predetermined period has elapsed (S33), the fluid cylinder 83 is operated, the slide gate 82a of the small capacity hopper 82 is closed (S34), and the swing chute 80 is swung to the lower position (S35). Begins to accumulate in the small capacity hopper 82. Until the gate open signal is sent, the swing chute 80 of the workpiece transfer section 28 swings at the lower position (S36), and the preform 1 slides on the swing chute 80 and is stored in the small capacity hopper 82. It is done. Since the preform 1 falls on the small-capacity hopper 82 while sliding on the swing chute 80, the fall distance is small and is not damaged. In addition, since the swing chute 80 is swinging, the preform 1 is averaged and stored in the small capacity hopper 82 without being collected in one place.

  Next, FIG. 10 shows the transfer process of the container rotating unit 24 and the process performed by the workpiece transfer unit 28.

  After step S12 of FIG. 7, the container rotation unit 24 is rotated (S40), the drive motor 60 of the container rotation drive unit 50 is operated, the rotation shaft 46 is rotated, and the container holding assembly 40 is rotated at a predetermined angle. For example, it is rotated up to 80 degrees. Then, N = 0 is set (S41), and when the gate open signal is sent (S42), the take-out conveyor 84 is moved and the belt conveyor 84d is moved for a predetermined time (S43). The preform 1 in the small capacity hopper 82 is smoothly moved onto the take-out conveyor 84 by the inching of the take-out conveyor 84.

Then, the take-out conveyor 84 is activated to rotate the belt conveyor 84d (S44). Further, the angle from the angle sensor 54 representing the rotation angle of the rotary shaft 46 is taken in (S45), and the forward stroke of the input conveyor 86 is determined according to this angle and the value of N (S46). This is because, as shown in FIG. 6, the stroke at which the input conveyor 86 enters the container 4 varies depending on the inclination angle of the container 4. Further, N is the entry, put the conveyor 86, a number of already enters the container 4 at the same rotational stop position of each container 4, a first time, in a · · · N _0-th, on what time of entry It is counted to change the stroke.

  The drive motor 96 is actuated to drive the input conveyor slide mechanism 90 for the determined forward stroke, and the input conveyor 86 is advanced (S47). The preform 1 on the belt conveyor 84d of the take-out conveyor 84 moves thinly and widely from the chute 84e to the input conveyor 86, and at the same time, the input conveyor 86 enters the inside through the opening of the inclined container 4 (FIG. 6 (a). )). Further, air from the blower is blown out from the air blow nozzle 98.

  Next, the drive motor of the input conveyor 86 is operated to rotate the belt conveyor 86d (S48), and the drive motor 96 is operated in the opposite direction to retract the input conveyor 86 (S49). Thereby, the preform 1 on the belt conveyor 86d of the input conveyor 86 can be transferred to the container 4 thinly and widely. At this time, since the container 4 is sufficiently inclined, the preform 1 does not fall into the container 4 and can be transferred with little impact.

Increments the entry number N (S50), when N does not reach the predetermined value N ₀ of a predetermined frequency of entrance, the process returns to step S42, and repeats the steps. At this time, the forward stroke of the input conveyor 86 changes, and the preform 1 is transferred from the position where the preform 1 was transferred to the container 4 last time (see FIG. 6B). The predetermined value N ₀ of frequency of entrance, it is also possible to change depending on the container inclination angle.

The approach number N reaches a predetermined value N ₀ (yes in S51), the driving motor 60 of the container rotation drive unit 50 is operated to rotate the rotary shaft 46 above and opposite direction a predetermined angle, to return the inclination (S52).

  Next, returning to step S41, the steps are repeated (see FIGS. 6C to 6H), and the inclination angle of the container 4 is gradually reduced. After loading, the transfer process for the container 4 ends.

  As shown in FIG. 6, the container 4 tilts and the input conveyor 86 enters from the opening of the container 4 to transfer the preform 1, so that the fall distance can be reduced. It is possible to prevent the occurrence of scratches, cracks, etc. Further, since only the input conveyor 86 having a simple configuration enters the container 4, it is possible to prevent foreign matter from entering the container 4.

  In addition, since the apparatus has a simple configuration, the apparatus can be downsized and configured at low cost. It is also possible to process at high speed. Furthermore, the boxing process to the container 4 including the exchange of an actual container and an empty container can be smoothly performed on the preform 1 continuously supplied by a small capacity hopper or the like.
