The tooth transfer unit 130 is provided such that the first tooth transfer unit 131 and the second tooth transfer unit 132 having a height difference extend in series.

The first plaque transfer unit 131 is disposed lower than the plaque supply unit 110 to transfer the overturned plaque supplied from the plaque supply unit 110.

The first tooth transfer unit 131 forms a unit supply path 135 by a transfer guide plate 136 which is spaced apart from each other on the upper portion of the first transfer conveyor 133 which is rotated and extends upward.

Reference numeral 137 is an alignment bar support frame installed to be supported on the upper portion of the transfer guide plate 136 across the transfer direction, and reference numeral 138 is a plaque alignment bar for increasing alignment efficiency by interfering with the overturned teeth being transferred.

In order to avoid the complexity of the drawings, a structure in which three unit supply paths 135 are provided side by side is illustrated, and the number of applied unit supply paths 135 may be constructed to have a different number from the illustrated example. to be.

The second plaque conveying unit 132 is disposed lower than the first plaque supplying unit 131 to transport the overturned plaque that is supplied by falling from the first plaque transferring unit 131.

The second tooth conveying unit 131 also forms a unit supply path 135 by means of a conveying guide plate 136 which is spaced apart from each other on the upper part of the second conveying conveyor 139 which is also rotated to extend upward.

Unlike the illustrated example, the dental transfer unit may be constructed such that the structure extends in series in three or more stages or extends to the bottom without being stepped.

The second transfer conveyor 139 is formed of a color that can easily distinguish the abalone currency.

The cameras 151 are respectively provided corresponding to the unit supply paths 135 to image the rolled-out plaques moving along the unit supply paths 135 and will be described with reference to FIG. 4 together.

The camera 151 is mounted in the imaging housing 153 spaced apart from the upper portion of the unit supply path 135 to image the unit supply path 135 and provide the captured image information to the control unit.

The selection path adjustment unit 160 moves the movement path to move to any one of the first selection path 161 and the second selection path 162 according to the size of the overturned plaque that has passed through the imaging area of the camera 151. It will be adjusted and explained with reference to FIG. 3 together.

The screening path adjusting unit 160 includes a path adjusting guide plate 165 and a motor 167.

The path adjustment guide plate 165 extends along the transport direction from the center of the unit supply path 135 to divide the unit supply path 135 into a first selection path 161 and a second selection path 162 ( The tip of 163) guides the overturned plaque conveyed by the rotation to enter the first sorting path 161 or the second sorting path 162.

The route adjustment guide plate 160 is formed in a plate shape, and when it is rotated clockwise, the entrance to the second selection path 162 is closed to guide the entry to the first selection path 161, and it is rotated counterclockwise. At the same time, the entrance to the first selection path 161 is closed to guide the entrance to the second selection path 162.

The motor 167 is connected to a rotational shaft that is a rotational center of the path adjustment guide plate 165 and is applied as a rotational driving unit that rotates forward and backward based on the rotational axis.

The motor 167 is mounted to be supported on the path adjusting housing 168 which is spaced apart from the unit supply path 135 and extends in a direction transverse to the transport direction.

It is a matter of course that various driving methods such as a structure in which the rotation driving unit for rotating the path adjustment guide plate 160 is rotated by being interlocked with the advance and retreat of the cylinder instead of the motor 167 can be applied.

The discharge chute 170 is installed to correspond to each of the first selection path 161 and the second selection path 162, and the overturned plaque that has been dropped through the first selection path 161 and the second selection path 162 is introduced. Discharge through the discharge path (172).

The overturned plaque discharged through the outlet 174 of the discharge chute 170 is collected in the receiving container 10 as illustrated in FIG. 4.

Here, the receiving container 10 is a cylindrical collection container (not shown) having a receiving space with an open upper part and capable of permeating with a rigid material, or a collection network formed in a mesh form to be pitched with a flexible material as shown. Can be applied.

In the case of applying the collection network, it is preferable that a hanger opening 176 through which the collection network can be walked is formed at the end of the discharge chute 170.

The discharge opening/closing unit 180 is configured to close and open the discharge passage 172 of the discharge chute 170, and a detailed structure will be described with reference to FIG. 4.

The discharge path opening and closing unit 180 includes a rotating shaft 181, a shielding plate 183, an arm 185, and a cylinder 188.

The rotating shaft 181 is mounted to extend to the outside of the discharge chute 170 so as to be rotatable in a direction crossing the discharge passage 172 of the discharge chute 170.

The shielding plate 183 is integrally joined to the rotating shaft 181 so as to be freely rotatable to open or shield the discharge path 172 by the rotation of the rotating shaft 181. The shielding plate 183 is formed with a pitcher hole capable of permeating smaller than the size of the overturned bill.

The arm 185 extends from the outside of the discharge chute 170 in a direction orthogonal to the extending direction of the rotating shaft 181.

The cylinder 188 rotates the rotating shaft 181 by the retraction of the rod 188a coupled to the arm 185. Reference numeral 103 is a support frame on which the cylinder is mounted.

Alternatively, when the shield plate 183 is closed for opening in the state where the discharge path 172 is closed, the cylinder 188 of the cylinder 188 when an overturned plaque is caught between the shield plate 183 and the inner wall of the discharge chute 170 It can be constructed to suppress damage due to the forced rotation operation, and an example thereof will be described with reference to FIGS. 5 and 6.

5 and 6, the shielding plate 283 is rotatably inserted into the rotating shaft 181 and is configured to open or shield the discharge path 172 by rotation.

That is, the shielding plate 283 is formed so that the rectangular shielding area 283b for shielding the discharge path 172 from the ring portion 283a surrounding the rotating shaft 181 so as to be relatively rotatable.

Here, the ring portion 283a is formed in a ring shape so as to completely surround the rotating shaft 181, and unlike the illustrated example, separation is suppressed in a direction orthogonal to the extending direction of the rotating shaft 181, and insertion into the rotating shaft 181 is prevented. Possibly a part can be formed in an open arc shape.

The rising interfering plate 286 is integrally coupled to the rotating shaft 181 and is linked to the rotation of the rotating shaft 181 so that the shielding plate 283 is raised to a position to close the discharge path 272, and the bottom of the shielding plate 283. It is formed in a plate shape of a size smaller than the shield plate 283 to interfere with.

According to this structure, when the rod of the cylinder 188 is retracted to open the discharge path 172 in a state where the shielding plate 283 is raised to a position to close the discharge path 172, the rising interference plate 286 This will descend. At this time, if the rolled-up plaque is not caught between the gaps of the shielding plate 283, the shielding plate 283 is rotated to the open position and descends with the rising interference plate 286. Unlike this, if the rolled-up plaque is sandwiched between the gaps of the shielding plate 283, unlike the rising interference plate 286, the shielding plate 283 is not lowered in the closed position.

Accordingly, damage due to forced rotation can be suppressed when an overturned plaque is caught between the shield plate 183 and the inner wall of the discharge chute 170.

The rotational position detection sensor 189 is installed to detect when the shield plate 183 is lowered to the open position and provide it to the control unit.

The rotational position detection sensor 189 is a proximity sensor that outputs a detection signal when the shielding plate 183 is detected within a certain distance, and unlike the illustrated example, outputs a signal in response to the presence or absence of contact of the shielding plate 183. Various sensors such as contact switches can be applied.

On the other hand, a weight piece 287 is installed at the bottom of the opposite side of the portion inserted into the rotation shaft 181 of the shielding plate 283 to induce a drop due to its own weight.

In addition, when the shield plate 283 is rotated to an open position to open the discharge path 272, the weight piece 287 is repelled when the weight piece 287 contacts the inner wall of the discharge chute 170 corresponding to the turning path of the weight piece 283. A rebound spring 288 mounted to provide elastic force is provided.

Reference numeral 289 is a seating pad coupled in a plate shape to disperse the amount of impact by widening the contact area on the upper surface of the repelling spring 288.

According to this structure, in the process of opening the discharge path 172 by the shield plate 283, when the rollover tooth is weakly between the edge of the shield plate 283 and the discharge chute 170, the reaction by the spring 288 again It can be induced to escape easily by process and vibration.

On the other hand, the control unit for controlling the selection process of the abalone plaque will be described with reference to FIG. 7 together.

The control unit 190 includes an operation unit 191, a display unit 192, an audio output unit 193 and a control unit 195.

The operation unit 191 is configured to set a supported function including a setting of a target quantity to be a packaging unit and an instruction to complete the storage container installation.

Reference numeral 191a denotes an installation completion instruction provided in correspondence with each discharge chute 170 so as to notify the completion of the installation when the storage container 10 is replaced with the discharge chute 170.

The display unit 192 is controlled by the control unit 195 to display display information. Reference numeral 192a is a packaging instruction indicator indicating that the target amount of the overturned plaque has been received in the storage container 10 to correspond to each discharge chute 170.

The sound output unit 193 is controlled by the control unit 195 to output sound.

The control unit 195 receives the image information captured by the camera 151 and determines the size of the rollover. If it is determined that there is an overturned plaque in the background information of the second transfer conveyor 139 for the image information captured by the camera 151, the control unit 195 grasps and grasps the size of the pixel area occupied by the overturned plaque The rollover size corresponding to the pixel area is calculated by referring to the look-up table, the calculated rollover size is compared with the reference size, and if it is less than the reference size, it is transferred to the first selection path 161, and according to the determined rollover size The selection path adjusting unit 160 is controlled to be transferred to the second selection path 162 when the selection path is, for example, a reference size or more.

The control unit 195 counts the number of roll-over plaques entering the discharge chute 170, and when the set target number is reached, the discharge route opening portion 172 of the discharge chute 170 is opened or closed to correspond to the set opening and closing conditions. (180) is controlled.

Preferably, the control unit 195 counts the number of roll-over plaques respectively introduced into the discharge chute 170 by using the image information captured by the camera 151 and the path adjustment information of the selection path adjustment unit 160.

That is, the overturned plaque is imaged by the camera 151 for one single supply path 135, and then the size of the overturned plaque is determined from the captured image information, and then screened to be transferred to the first selection path 161. When the path adjusting unit 160 is adjusted, the number of roll-over plaques that flows into the discharge chute 170 corresponding to the first sorting path 161 is counted so as to be accumulated one by one. The control unit 195 counts each discharge chute 170 while managing it as unique identification information. In this way, the control unit 195 controls the discharge path opening and closing unit 180 so that the discharge path 172 is closed for the discharge chute reaching the set target number among the discharge chutes 170, and resets the counting value to count again. And, when the waiting time set corresponding to the replacement time of the receiving container 10 accommodating the overturned plaque discharged from the outlet 174 of the discharge chute 170 passes, the discharge path opening and closing unit 180 is controlled to open the discharge path. do.

Here, the target number may be appropriately set, such as 500, and the waiting time may be appropriately set.

The control unit 195 processes the output chute to reach the target number through the sound output unit 193 and outputs voice guidance information that guides the replacement of the receiving container 10, and corresponds to the display unit 192 The packaging instruction indicator 192a is displayed.

Alternatively, the control unit 195 controls the discharge path opening and closing unit 180 so that the discharge path 172 is closed for the discharge chute 170 that has reached the target number, and then stops the installation of the operation unit 191 (191a) ) Can be rescued to control the discharge path opening and closing unit 180 so that the discharge path 172 is opened when the operation signal of) is received.

Alternatively, the operation unit 191 automatically switches the discharge path opening and closing unit 180 so that the discharge path is opened when the waiting time has elapsed, and when the operation signal of the completion of the installation unit 191a of the operation unit 191 is received, the discharge path ( 172) supports to select any one of the manual mode to control the discharge opening and closing unit 180 to be opened, the control unit 195 may be configured to process corresponding to the selected mode.

In addition, the control unit 195 controls the discharge path opening and closing unit 180 so that the discharge path 172 is opened, and then the shielding plate 283 is lowered to the open position from the rotational position detection sensor 189 for a set detection time. If it is not received, it can be constructed to output an action message corresponding to the occurrence of a failure of the shielding plate 283 through the sound output unit 193 by determining that it is not lowered by being caught in an overturned lung.

On the other hand, if a plurality of unit supply paths 135 are provided side by side, the adjacent sorting paths for the overturned money sorted and transferred by the sorting path adjusting unit 160 join the overturned money of the size classified under the same conditions. It can be constructed to reduce the number of discharge chutes 170 applied by being transported, and an example thereof will be described with reference to FIGS. 8 and 9.

Referring to FIGS. 8 and 9, for the sorting paths formed inside the rest of the screens except for the sorting paths formed on the outermost side of the overturned coins that have passed through the sorting path adjusting unit 160, the direction perpendicular to the transfer direction of the overturned teeth Constructed so that adjacent sorting paths are formed in the order of the first sorting path, the second sorting path, the second sorting path, the first sorting path, the first sorting path, and the second sorting path so that the overturned lungs selected by the same size condition are transferred. It is done.

In addition, when the adjacent selection paths are the same selection path, they are formed to be collected in one discharge chute in a confluence state.

That is, as compared with the structure of FIGS. 1 and 2, the outermost transport guide plate 136 corresponding to the single supply path 135 and the divided bulkhead 163 are still maintained, and the two internal transfer guide plates 136 are Is removed.

In this case, from left to right, the first selection path, the second selection path, the second selection path, the first selection path, the first selection path, the second selection path, and the central adjacent second selection path and second The transfer guide plate 136 between the two selection paths is removed and transferred through a single path by confluence, and the transfer guide plate 136 between the central adjacent first selection path and the first selection path is removed to join. By one single path. Therefore, compared to the structure illustrated above, the two discharge chutes 170 are reduced, so that the four discharge chutes 170 can be selected.

In this case, the control unit 195 is provided in each unit supply path 135 for the forward/reverse rotation of each motor 167 that adjusts the sorting path for the path selection direction between the adjacent motors 167 according to the sorting path described above. It should be constructed to control the rotational directions to be opposite to each other.
