[0013]

According to the opening device of the present invention, the pair of rollers is driven to rotate in a predetermined direction, and when the pair of rollers sandwiches the tip of the package, the pair of rollers is stopped. The nearby space is partially cut to form an opening in the package. Thereafter, the roller pair is displaced, and the transport path of the package is changed to another transport path different from the predetermined transport path. Then, when the roller pair is driven to rotate in the predetermined direction after the change of the transport path, the packaging material is nipped by the roller pair and transported along the other transport path, but the packaged object is nipped by the roller pair. The packaging material cannot be moved along the other transport path, and the packaging material is torn from the opening. When the roller pair is further driven to rotate, the packaging material is further transported along the other transport path described above, and the tear in the opening is widened, the packaged object is taken out of the package, and the packaged material and the packaging material are separated. You. For this reason, if the opening device of the present invention is used, the package can be automatically opened and the packaging material and the packaged object can be separated.

Next, the operation of this embodiment will be described. FIG. 9 shows the slide pack 3 in the sorting and opening device 1.
3 is a flowchart showing an operation until the device 2 is moved to the opening device 10. First, it is determined whether or not the suction cup 51 is at the initial position (step S1). If not, the pulse motor 55 and the pulse motors 58A, 58B are driven by the third and fourth motor driving units 71, 72. The suction cup 51 is driven to move to the initial position (Step S)
2). Next, it is determined whether or not an input for selecting the slide pack 32 has been made (step S3). When the operator operates the instruction button 5 of the instruction unit 4 to input a desired instruction for selecting the slide pack 32, step S3 is performed. Are affirmed, and the third and fourth motor driving units 71 and 72
The pulse motor 55 and the pulse motors 58A, 5
8B is driven to move the suction cup 51 from the initial position to the position of the desired package cartridge 2 in which the specified slide pack 32 is stored (step S).
4). This movement is performed by, for example, the package cartridge 2.
A coordinate position is set for each pulse, and a pulse necessary to move the suction cup 51 from the initial position to the coordinate position is transmitted from the third and fourth motor driving units 71 and 72 to the pulse motor 55 and the pulse motor 58A, 58B.

When the suction cup 51 moves to a desired position of the package cartridge 2, the suction cup driving section 73 drives the suction cup supporting section 52 to move the suction cup 51 upward (step S5). At the same time, the suction drive unit 74 drives the suction means 59 to apply a negative pressure to the suction cup 51 (step S6). Here, when the slide pack 32 is sucked by the suction cup 51, the negative pressure in the suction means 59 rises. Therefore, the pressure acting on the suction means 59 is detected by the suction drive unit 74, and whether the negative pressure has risen is determined. Is determined (step S7). When step S7 is denied, suction is further continued, and when step S7 is affirmed, the suction cup driving section 73 moves the suction cup supporting section 52 downward (step S8). Thereby, the slide pack 32 is taken out of the package 42 in the package cartridge 2.

Next, in a state where the slide pack 32 is attracted to the suction cup 51, the third and fourth motor driving sections 7 are moved.
1, 72, the pulse motor 55 and the pulse motor 5
8A and 58B are driven to move the suction cup 51 to the position of the insertion opening 10A of the opening device 10 (step S9). After the movement, the suction drive unit 74 reduces the suction force of the suction unit 59 (step S10), and the third motor drive unit 71
Drives only the pulse motor 55 to insert the slide pack 32 into the insertion slot 10A (step S11).
When the slide pack 32 is nipped by the roller pair 12 of the opening device 10 and the slide pack 32 is drawn into the opening device 10, the slide pack 32 separates from the suction cup 51. Here, when the slide pack 32 is separated from the suction cup 51, the negative pressure in the suction means 59 decreases. Therefore, the pressure acting on the suction means 59 is detected by the suction drive unit 74, and it is determined whether or not the negative pressure has decreased. (Step S1
2). If step S12 is negative, step S1
Returning to step 1, the slide pack 32 is further inserted into the opening device 10 from the insertion opening 10A, and if step S12 is affirmed, it is determined that the slide pack 32 has been drawn into the opening device 10 and suction by the suction means 59 is stopped (step S12). S
13), and third and fourth motor drive units 71, 7
2, the pulse motor 55 and the pulse motor 58A,
58B is driven to move the suction cup 51 to the initial position (step S14), and the process ends. The above is the operation until the slide pack 32 is inserted into the opening device 10.

FIG. 10 is a flowchart showing the operation of the opening device. In the initial state, the roller pair 12 is in a state in which the rollers 12A and 12B are arranged in the vertical direction on the paper as shown in FIG.
It is assumed that she has been evacuated. First, the tip detection sensor 1
It is determined whether or not the leading end of the slide pack 32 has been detected by 6A (step S21). When the leading end is detected as shown in FIG. 11, the first motor driving unit 61 drives the motor 23 to drive the motor 23 in FIG. Roller pair 12 in the direction of arrow C
Is rotated (step S22). At the same time, the ironing member 13 is advanced to the transport path 11 by the ironing member drive unit 63 (step S23).

Here, the slide pack 32 is conveyed in the direction of arrow A while being sucked by the suction cup 51. When the tip of the slide pack 32 is pinched by the roller pair 12, the suction cup 51 comes off, as shown in FIG. The slide pack 32 is transported along the transport path 11 by the roller pair 12 (step S24). At this time, since the squeezing member 13 has advanced to the conveyance path 11, if the conveyance by the roller pair 12 is continued, the slide 30 in the slide pack 32 is squeezed by the squeezing member 13, and as shown in FIG. The slide pack 32 moves in the space portion 34 in a direction opposite to the transport direction of the slide pack 32, and a cutting margin is formed on the slide pack 32 in the transport direction. When the slide 30 comes into contact with the rear end portion 34A of the space portion 34, the slide pack 3
Since the roller 2 is no longer conveyed in the direction of arrow A, the rotational load of the roller pair 12 increases, and the supply current to the motor 23 that rotates the roller pair 12 increases. Therefore, the supply current to the motor 23 is monitored by the ammeter 24 to determine whether the supply current has increased (Step S).
25) If step S25 is affirmed, the driving of the motor 23 is stopped by the first motor drive unit 61 to stop the roller pair 12 (step S26), and the ironing member 13 is driven by the ironing member drive unit 63. The transport path 1
1 (step S27). If step S25 is denied, the process returns to step S24 to continue the transport.

Next, the motor 23 is driven in the reverse direction by the first motor drive section 61 to rotate the roller pair 12 in the reverse direction.
That is, the slide pack 32 is transported along the transport path 11 in the direction opposite to the previous direction by rotating the slide pack 32 in the direction of arrow D in FIG. 14 (step S28). Then, it is determined whether or not the rear end of the slide pack 32 is detected by the rear end detection sensor 16B (step S29). If step S29 is denied, the process returns to step S28, and the conveyance in the reverse direction is continued. If step S29 is affirmative, the driving of the motor 23 is stopped by the first motor driving unit 61 to stop the roller pair 12 (step S30), and the cutter 14 is moved by the cutter driving unit 64 in the direction of arrow B in FIG. And the slide pack 32 is partially cut (step S31).

Here, the rear end detection sensor 16B is configured such that the cutting position by the cutter 14 is the space portion 34 of the slide pack 32.
It is positioned so that it is located in. Thereby, as shown in FIG. 15, the slide pack 32 is cut, and an opening 80 is formed in the vicinity of the sticking portion 35 on the side sandwiched by the roller pair 12.

After the cutting, the motor 22 is driven by the second motor drive unit 62 to rotate the gear 20 by 90 degrees in the counterclockwise direction on the paper as shown in FIG. 16 to displace the roller pair 12 (step S32). ). Then, the motor 23 is driven by the first motor drive unit 61 to rotate the roller pair 12 in the direction of arrow C in FIG. 16 (step S33). Here, since the slide 30 is not pinched by the roller pair 12, when the distal end side sticking portion 35 of the slide pack 32 is pulled downward, a tear 81 is formed in the slide pack 32 as shown in FIG. Further, when the tip side adhering portion 35 is pulled by the roller pair 12, the tear 81 expands, and the slide 30 jumps out of the opening 80 as shown in FIG. Here, since the guide plate 15 is provided in the transport path 11, even if the distal end side sticking portion 35 of the slide pack 32 is pulled downward, the slide pack 32 does not tilt upward.

When the roller pair 12 is further rotated, FIG.
As shown in (2), the packaging sheet 33 and the slide 30 are completely separated. Then, as shown in FIG.
Are stored in the cartridge 7 in a line, and the packaging sheet 33 is
Are discarded in a waste box 17.

When the packaging sheet 33 separated from the slide 30 comes off the roller pair 12, the load on the roller pair 12 is reduced, and the motor 23 that rotates the roller pair 12 is rotated.
Supply current to the motor becomes smaller. Therefore, when it is detected that the supply current to the motor 23 has decreased (step S34), the first motor driving unit 61
By stopping the driving of the roller pair 12, the roller pair 12 is stopped (step S35), and the process ends.

As described above, by using the opening device according to the present embodiment, the slide pack 32 can be automatically opened and the slide 30 and the packaging sheet 33 can be separated.
In addition, since the cutting of the slide pack 32 is partially performed as shown in FIG. 15, the packaging sheet 33 does not separate after the cutting, and the processing of the packaging sheet 33 after the slide 30 is taken out is facilitated. Furthermore, since the separated packaging sheet 33 is transported by the roller pair 12,
It is pressed by the roller pair 12 and does not become bulky, so that the packaging material can be easily disposed of.

In the above-described embodiment, the ironing member 13 is provided to move the slide 30 to the rear end 34A in the space 34 of the slide pack 32.
The slide pack 32 may be hardened only by the roller pair 12 without providing the ironing member 13.

Further, in the above embodiment, the slide 30 in the slide pack 32 is attached to the rear end 3 of the space 34.
4A is detected in step S25 in FIG.
In FIG. 20, the detection is performed by detecting that the supply current to the motor 23 has increased. As shown in FIG. 20, a reflection-type detection that detects the tip of the slide pack 32 at a predetermined position on the downstream side of the roller pair 12 is performed.

41), when the tip is detected, the first motor driving unit 61
Drives the motor 23 to rotate the roller pair 12 similarly to the above embodiment (step S42).

Here, the slide pack 32 is conveyed while being sucked by the suction cup 51, and the suction cup 51 comes off when the leading end of the slide pack 32 is sandwiched by the roller pair 12. Then, it is determined whether or not the tip of the slide pack 32 is nipped by the roller pair 12 (step S43), and step S43 is performed.
If the result in Step 43 is affirmative, the roller pair 12 is stopped (Step S44). Here, when the leading end of the slide pack 32 is sandwiched between the roller pair 12, the load on the roller pair 12 increases, and the supply current to the motor 23 that rotates the roller pair 12 increases. Therefore, the determination in step S43 may be made by monitoring the supply current to the motor 23 with the ammeter 24 and determining whether the supply current has increased. Alternatively, the determination in step S43 may be performed by providing a sensor that detects the rear end of the slide pack 32 and detecting the position of the rear end of the slide pack 32 using this sensor.

Then, the cutter 1 is driven by the cutter driving section 64.
4 in the direction of arrow B in FIG.
2 is partially cut (step S45). After the cutting, in steps S46 to S49, the same processing as steps S32 to S35 in FIG. 10 is performed to separate the packaging sheet 33 from the slide 30.

In each of the embodiments described above, the apparatus for opening the slide pack 32 in which the slides 30 for chemical analysis are packaged is described. If it is, it can be applied to anything.
