The stopper 103 is driven and controlled by the controller 190 at predetermined time intervals in consideration of the time required for the pouch detecting unit 140 to detect whether the pouch P is in a normal state.

As shown in FIG. 4, the stopper 103 has a left-right direction A between a blocking position capable of blocking movement of the pouch P and a withdrawn position withdrawn from the blocking position to allow movement of the pouch P. FIG. It may be provided to reciprocate). The stopper 103 shown in FIG. 4 is in the retracted position. When the detection of the normal state of the preceding pouch is completed by the control of the controller 190, the stopper 103 is moved to the retracted position. Thereby, the pouch may then be supplied to the pouch sensing unit 140.

Here, the stopper 103 may be installed in the main body frame 101 of the pouch automatic selection device 100 to reciprocate.

The pouch P may be disposed on the guide rail 131 such that the front surface P1a or the rear surface P1b of the pouch body P1 is parallel to the moving direction B of the pouch P. Can be. This is for arranging a plurality of pouches P on the guide rail 131.

In addition, the pouch detecting unit 140 may include a light source (not shown) and an optical system (not shown) of a lens and / or a mirror for focusing light emitted from the light source (not shown) on the mark M. ) May be further included.

As shown in FIG. 4, the posture of the pouch P whose movement is stopped by the stopper 103 is changed in the process of moving to the pouch detecting unit 140. In more detail, in the previous step of the stopper 103, the front (P1a) or the rear (P1b) of the pouch (P) is directed toward the pouch movement direction (B), the pouch detection unit 140 In order to recognize the marks H, N, and M formed on the front surface P1a or the rear surface P1b, the front surface P1a and the rear surface P1b of the pouch P face the pouch detection unit 140. It should be rotated by a predetermined angle so that Here, when the pouch detecting unit 140 is photographed at an angle of about 90 degrees with respect to the pouch movement direction B, the pouch P may rotate by 90 degrees correspondingly.

To this end, the pouch automatic sorting device 100 further includes a pouch contacting part 107 which rotates the pouch P in contact with one side of the pouch body P1 based on the inlet part P3. Can be.

Like the pouch indicated by a dotted line in FIG. 4, the pouch may rotate 90 degrees as one side of the pouch body contacts the pouch contacting part 107. As a result, the front surface P1a or the rear surface P1b of the pouch P faces the pouch detection unit 140. Accordingly, the pouch detecting unit 140 may detect the presence or absence of the mark formed on the pouch body P1.

The pouch blocking unit 150 is provided to selectively prevent the pouch P from moving along the pouch movement path.

The pouch blocking unit 150 may be provided similarly to the stopper 103 described above. In more detail, the pouch blocking unit 150 has a left and right direction between a blocking position capable of blocking movement of the pouch P and a retracted position withdrawn from the blocking position to allow movement of the pouch P. It may be provided to reciprocate to D).

The pouch blocking unit 150 may contact the inlet portion P3 of the pouch P to prevent movement of the pouch P.

The control unit 190 controls the pouch blocking unit 150 so that the pouch is loaded on the pouch loading unit 120 when the pouch is in a normal state as a result of the detection of the pouch detecting unit 140. That is, when the pouch is determined to be in a normal state, the pouch blocking part 150 is moved to the retracted position so that the pouch can be transferred to the pouch loading part 120. As a result, the pouch may be loaded into the pouch loading part 120.

In addition, the controller 190 controls the pouch blocking unit 150 so that the pouch is not loaded into the pouch loading part when the pouch is abnormal.

For example, it is assumed that the normal pouch P has a mark M formed on the front surface P1a of the pouch body P1, as shown in FIG. As shown in FIG. 4, in the case of the pouch PA2 positioned in front of the pouch sensing unit 140, the back surface P1b is photographed by the pouch sensing unit 140. As a result, the controller 190 determines that there is no mark M from the image captured by the pouch detector 140, and determines the pouch PA2 to be in an abnormal state.

Here, the abnormal state may be a case where the positions of the front surface P1a and the rear surface P1b of the pouch PA2 are reversed or the unidentified product, that is, the defective product, which has not been properly processed.

In the above-described example, when the pouch PA2 is determined to be in an abnormal state, the controller 190 controls the pouch blocking unit 150 such that the pouch blocking unit 150 is in a blocking position. The pouch PA2 may be moved to a defective pouch loading unit (not shown) along the pouch recovery path not shown. In some cases, the pouch PA2 may be adsorbed and separated from the pouch movement path. In addition, when it is determined that the front and rear surfaces of the pouch PA2 are changed as necessary, the pouch PA2 may be re-transmitted to the pouch supply unit 110.

On the other hand, the pouch automatic selection device 100, in consideration of the detection time of the pouch detection unit 140 and the downstream pouch detection unit 140 further disposed downstream along the pouch movement direction (B). A posture disposed between the stopper 103 for controlling the movement of the pouch, the upstream pouch detecting unit 140 and the downstream pouch detecting unit 140, and inverting the posture of the pouch to a normal state. A changer 160; It may further include a pouch blocking unit 150 disposed downstream. Of course, if necessary, the downstream pouch detecting unit 140 and the posture changing unit 160 may be omitted.

In some cases, the pouch automatic sorting device 100 is disposed in the upstream and downstream sides of the pair of pouch detection unit 140 along the pouch movement direction (B), respectively, as shown in FIGS. Instead, the front surface P1a and the rear surface P1b of the pouch PA2 may be simultaneously photographed by being disposed opposite to each other on both sides of the pouch PA2. In this case, the posture change unit 160 may be omitted.

When it is determined that the pouch PA2 is in an abnormal state, the controller 190 may control the posture changing unit 160 to change the posture of the pouch PA2. In more detail, the posture change unit 160 may allow the inlet portion P3 of the pouch PA2 to be rotated by 180 degrees. As a result, the opposite surface P1a which is not photographed by the upstream side pouch detection unit 140 may be exposed toward the downstream side pouch detection unit 140. Here, in the pouch PA1 disposed in front of the downstream side pouch detection unit 140, the pouch PA2 detected by the upstream side pouch detection unit 140 has a posture by the posture changing unit 160. Has changed.

The downstream pouch detecting unit 140 photographs the front surface P1a of the pouch PA1 whose posture is changed. The controller 190 checks whether the mark M is on the front surface of the pouch PA1 based on the result detected by the downstream pouch detector 140, that is, the captured image. If the mark M is present, the pouch PA1 is determined to be in a normal state, and the pouch blocking part 150 disposed at the downstream side is controlled to be in the retracted position. As a result, the pouch PA1 may be moved toward the pouch loading part 120.

If it is determined that the mark M is not present on the front surface of the pouch PA1 whose posture is changed, the controller 190 determines the pouch PA1 as a defective product even in the above-described abnormal state. Thus, the control unit 190 prevents the defective pouch PA1 from being transferred to the pouch loading unit 120 by keeping the pouch blocking unit 150 in the blocking position. Here, the defective pouch PA1 may be transferred to the defective pouch loading unit (not shown) along a recovery path not shown.

The pouch loading part 120 may include the normal pouch loading rails 121, 123, and 125 formed with guide grooves 121a, 123a, and 125a corresponding to the guide grooves 131a of the guide rail 131. have.

Here, the pouch loading part 120 is to temporarily store the selected normal state pouch. When the pouch automatic sorting apparatus 100 is directly connected to the apparatus for filling the normal pouch, the pouch loading part 120 may be a guide rail for transferring the steady state pouch to the contents filling apparatus.

When the pouch in the normal state passing through the pouch blocking unit 150 reaches the entry position F of the pouch loading unit 120, the pusher 170 is driven to drive the pouch in the entry position to the normal pouch loading rail. Can be moved to (121, 123, 125).

Here, the pusher 170 may include a cylinder driven by hydraulic pressure or pneumatic pressure.

In addition, the pouch automatic sorting device 100, if the normal pouch loading rails (121, 123, 125) are all filled with the pouch, the normal pouch loading rails (121, 123, 125) to a different position and new It may further include a cassette replacement unit 180 for moving the empty loading rail to the entry position (F).

Here, when the pouch automatic sorting apparatus 100 is directly connected to the contents filling apparatus for filling the contents of the pouch body of the normal pouch, the cassette replacement unit 180 may be omitted.
