1 and 2, the flat inserter 10 according to this embodiment includes a supply unit 100, an input unit 200, a transfer unit 300, a conversion unit 400, and an outlet unit 500. include

The supply unit 100 is to supply a plurality of large troughs 20, the supply conveyor 102 extending in the first direction (X) is provided, on the supply conveyor 102, the plurality of large The cylinders 20 are supplied in the direction of the input unit 200 .

The input unit 200 is disposed adjacent to the supply unit 100, and the large bins 20 supplied from the supply unit 100 are divided one by one, that is, the transfer unit 300. provided as

In this case, the input unit 200 divides the large cylinders 20 supplied along the first direction (X) into individual pieces, in a second direction perpendicular to the first direction (X) ( It is provided to the transfer unit 300 along Y).

In addition, the transfer unit 300 transfers the large barrels 20 input from the input unit 200 one by one, and supplies them to the conversion unit 400 .

In this case, the transfer unit 300 may check again whether or not the large bins 20 are additionally supplied one by one so that the large bins 20 can be supplied one by one.

On the other hand, the transfer unit 300, as shown in Figure 2, may be provided with a transfer cover 301 forming a transfer space 302 in which the actual large barrels are transferred, and the transfer space 302 is on the ground. A separate transfer support 303 may be provided at the lower portion to be located at a predetermined height from the .

This transfer cover and transfer support part, the transfer unit 300, of course, the description is omitted, but may be provided to correspond to the supply unit 100, the input unit 200 and the conversion unit 400, It is obvious that the size of the transfer space 302 formed by the transfer cover or the height of the transfer support 303 can be variously designed and changed.

In this way, the direction of the large barrels 20 supplied through the transfer unit 300 is changed by the switching unit 400, and finally flows out through the outlet unit 500, although not shown. , can be supplied as a sorter.

That is, the conversion unit 400 converts the transfer direction so that the large cylinder 20 provided by standing up in the vertical direction through the transfer unit 300 is supplied in a state lying in the horizontal direction, the outlet unit ( 500) is provided.

Hereinafter, detailed configurations of the flat inserter 10 will be described in more detail with reference to the drawings.

Figure 3 is a plan view showing the inside of the input unit of Figure 1; Figure 4 is an image showing the inclined state of the large cylinder when the large cylinder is put using the flat inserter of Fig. 1 . 5 is an image illustrating the input roller unit of FIG. 3 .

3 to 5 , the input unit 200 includes a first input base 210 , a second input base 220 , an input roller part 230 , a pressure roller 240 , and a reverse roller part 250 . ), and a first conveying roller 260 and a second conveying roller 270 .

The first input base 210 and the second input base 220 constitute a predetermined base flame, respectively, and the components of the input unit 200 are the first input base 210 or the input unit 200, respectively. It may be positioned and fixed on the second input base 220 .

In this case, the first input base 210 may have a relatively long rectangular shape in the second direction (Y) as shown, and the second input base 220 is relatively long in the first direction (X). ) and may have a long rectangular shape.

Thus, along the first direction (X), the supply space 101 to which the large cylinders 20 are supplied may be formed.

In addition, the large cylinders 20 are transported one by one in the second direction Y along between the first input base 210 and the second input base 220 .

The input roller unit 230 classifies and transports the large cylinders 20 supplied to the supply space 101 in the first direction (X) in the second direction (Y) one by one, It includes a driving roll 231 , an input roller 232 , a suction unit 233 , and an input belt 234 .

The input driving roll 231 provides a rotational driving force, and the input roller 232 is positioned to be spaced apart from the input driving roll 231 by a predetermined distance, and is connected to each other by the input belt 234 and rotates.

In this case, the input drive roll 231 and the input roller 232 may rotate in a clockwise direction, and accordingly, the input belt 234 is also formed between the input drive roll 231 and the input roller 232 . It can be moved by rotating clockwise while being wound along the outer circumferential surface.

Thus, the large cylinder 20 supplied in the direction of the arrow from the supply space 101 is in close contact with the input belt 234 along the second direction Y according to the transfer of the input belt 234 . In the arrow direction shown, the first input base 210 and the second input base 220 is transported along the boundary.

The suction part 233 is located between the input driving roll 231 and the input roller 232 , that is, inside the input belt 234 which is rotated.

The suction part 233 sucks air, and as the suction part 233 sucks air, the large cylinder 20 supplied to the supply space 101 is more than the input belt 234 . It can be easily adhered, and the adherence state can be better maintained.

In this case, as shown in FIG. 5 , a plurality of through-holes 236 are formed on the input belt 234 , and accordingly, the suction force of the air sucked in the suction unit 233 is applied to the through-holes ( 236 to the larger barrel 20 .

On the other hand, as shown in FIG. 4 , when a plurality of the large cylinders 20 supplied through the supply space 101 are located in the supply space 101 , the upper part is naturally the input unit 200 . It may be positioned so as to be inclined toward the

However, when the upper portion of the large cylinders 20 is inclined toward the input unit 200 in this way, the large cylinders 20 are not uniformly in close contact with the input belt 234 , and thus the input It becomes difficult to put the large cylinders one by one into the transfer unit 300 by the roller unit 230 .

Accordingly, in this embodiment, as shown in FIG. 5 , a protrusion 235 is formed on the upper side of the input roller 232 , and the protrusion 235 is formed to protrude in a direction toward the supply space 101 . do.

In this case, the protrusion 235 may be fixed to be positioned in a direction toward the supply space 101 regardless of the rotation of the input roller 232 .

Thus, when the upper portions of the large cylinders 20 are inclined toward the input unit 200 as in FIG. 4 , the upper portions of the large cylinders 20 stand vertically in the opposite direction to the inclining direction again. to assist in positioning.

On the other hand, the protrusion 235 is formed so that the degree of protrusion from the input roller 232 toward the input driving roll 231 naturally increases, so that the large cylinder 20 moves in the second direction (Y). so that the input can be induced more naturally.

The pressure roller 240 is disposed adjacent to the input roller part 230 and protrudes toward the supply space 101 to a degree similar to that of the input roller part 230 .

As shown, the pressure roller 240 may be arranged in plurality.

The pressure roller 240 determines whether the large cylinders 20 provided through the supply space 101 are in contact with the pressure roller 240 to press the pressure roller 240 .

That is, when the large cylinders 20 are in contact with the pressure roller 240 and a pressure signal is generated from the pressure roller 240, the large cylinders are pressed too much or, as shown in FIG. In a state where the degree of inclination of the normals is excessively severe, it may be a situation in which a large normal input operation by the input roller unit 230 cannot be easily performed.

Therefore, when a pressure signal is generated from the pressure roller 240, or when the pressure signal is generated larger than a preset value (that is, when the large cylinders press the pressure roller over a preset value) ), to stop the operation of the input roller unit 230 and to reconfirm the state of the large barrels located in the supply space 101 .

In this case, by reconfirming the state of the large cylinders, if necessary, the supply conveyor 102 for supplying the large cylinders may be transferred in the opposite direction, that is, in a direction away from the input roller unit 230 . Thus, in a state in which the large cylinders are positioned to stand more vertically, they can be re-transferred toward the input roller unit 230 .

On the other hand, the position confirmation sensor 241 may be provided on the pressure roller 240, and the position confirmation sensor 241 is in front of the pressure roller 240, that is, on the supply space 101, the large cylinder ( 20) is located or not, and when the large cylinder 20 is located, the driving for the transfer of the large cylinder 20 including the input roller 230 is started.

The reverse roller unit 250 is disposed to face the input roller unit 230 , and includes a reverse driving roll 251 , a reverse rotation roll 252 , a reverse belt 253 , and a support unit 254 .

The reverse roller unit 250 is positioned on the second input base 220 so as to face the input driving roll 231 of the input roller part 230 as a whole.

This is because the input belt 234 of the input roller unit 230 is partially exposed to the supply space 101 to be in contact with the large cylinder 20 .

In addition, the reverse roller unit 250 is to be rotated or transported in the opposite direction to the rotation or transport direction of the input roller unit 230, thereby preventing the large cylinder 20 from overlapping a plurality of input. do.

Specifically, the reverse driving roll 251 provides the rotation driving force of the reverse roller unit 250 , and the reverse driving roll 251 and the reverse rotation roll are provided by the rotation driving force of the reverse driving roll 251 . (252), rotation or transfer of the reverse belt 253 connected along the support unit 254 is performed.

In this case, the reverse belt 253, and the input belt 234, at a position facing each other, should be transferred in opposite directions. Accordingly, the reverse belt 253 must also rotate in a clockwise direction as a whole.

To this end, the reverse driving roll 251 should also rotate clockwise, and the reverse rotation roll 252 controlling the tension of the reverse belt 253 should rotate counterclockwise.

In addition, the support rollers 255 included on the support unit 254 may rotate clockwise in the same manner as the transfer direction of the reverse belt 253 .

That is, the reverse belt 253 is rotated in a clockwise direction, so that the actual large cylinder 20 is transferred in a direction that prevents it from being transferred in the second direction Y indicated by the arrow. When a plurality of large cylinders overlap and are transferred in the second direction (Y), this may be blocked.

For example, when two first and second large cylinders overlap and are fed into the transfer unit 300 through the input roller unit 230 , one side of the first large cylinder is the input belt 234 . The conveying force is provided in the direction (positive second direction (+Y)) toward the conveying unit 300 by close contact with, but the other side of the second large cylinder in close contact with the first large cylinder is the reverse belt ( 253), the feed force is provided in the opposite direction, that is, in the direction toward the supply space 101, which is the negative second direction (-Y).

Thus, only the first large cylinder is provided toward the transfer unit 300 , the second large cylinder may be blocked from being provided to the transfer unit 300 .

Meanwhile, the support unit 254 includes a plurality of support rollers 255 and a support frame 256 to which the support rollers 255 are fixed.

In this case, the support frame 256 is a frame rotatable with respect to the center, and when the support frame 256 rotates counterclockwise, for example, the input belt 234 and the reverse belt 253 are The gap between them increases, and when the support frame 256 rotates clockwise, the gap between the input belt 234 and the reverse belt 253 decreases.

Through this, it is possible to adjust a gap between the input belt 234 and the reverse belt 253, so that even if the large normal sizes input through the input roller unit 230 are different from each other, the large It is possible to provide an appropriate adhesive force with respect to normal.

The first transfer roller 260 is positioned on the first input base 210 and is disposed adjacent to the input roller unit 230 in the second direction (Y).

Similarly, the second conveying roller 270 is positioned on the second input base 220 and is disposed adjacent to the reverse roller unit 250 in the second direction (Y). In this case, the second transfer roller 270 may be disposed to face the first transfer roller 260 .

Thus, the first and second transfer rollers 260 and 270 additionally transfer the large cylinder 20 that is input through the input roller unit 230 to induce the input of the transfer unit 300 . will do

In this case, the number or arrangement of the first and second transfer rollers 260 and 270 is a design change that can be variously changed.

As described above, the large cylinders 20 are put into the transfer unit 300 through the input unit 200 , and the transfer state in the transfer unit 300 will be described below.

Figure 6 is a plan view showing the inside of the transfer unit, the switching unit and the outlet unit of Figure 1; 7 is a plan view illustrating the inside of the transfer unit of FIG. 6 in detail. FIG. 8 is a plan view showing the inside of the switching unit and the outlet unit of FIG. 6 in detail.

6 and 7, the transfer unit 300 transfers the large cylinders 20 introduced through the input unit 200 in the second direction (Y), the conversion unit 400 provided as

The transfer unit 300 includes a first acceleration unit 310 and a second acceleration unit 320 continuous to the first acceleration unit 310 .

In addition, the transfer unit 300, the first front end sensor 311 located at the front end of the first acceleration unit 310, the first rear end sensor 312 located at the rear end of the first acceleration unit 310, It further includes a second front end sensor 321 located at the front end of the second acceleration unit 320 , and a second rear end sensor 322 located at the rear end of the second acceleration unit 320 .

The first shear sensor 311 is a sensor for measuring the length of the large cylinder 20 transferred to the first acceleration unit 310 , and the second shear sensor 321 is the second acceleration unit 320 . It is a sensor for measuring the length of the large barrel 20 transported to the

For example, the first and second front end sensors 311 and 321 may acquire information on the moving speed and moving time of the large barrel to obtain information on the length of the large barrel.

In the present embodiment, by obtaining the length information of the large cylinder 20 from the first front end sensor 311 and the second front end sensor 321, respectively, in the two different sensors 311 and 321 When the obtained length information of the large cylinder 20 is different from each other, the transfer of the transfer unit 300 is stopped.

That is, if the length information of the large cylinder 20 obtained from the two different sensors 311 and 321 is different from each other, as will be described later, the large cylinders transported through the transfer unit 300 are one by one. Since it may be regarded as a state in which a plurality of pieces are transferred to each other overlapping each other instead of being transferred individually, the transfer of the transfer unit 300 must be stopped.

The first rear end sensor 312 and the second rear end sensor 322 are sensors for stopping the transfer of the transfer unit 300 , and the first acceleration unit through the first rear end sensor 312 . Feedback control for recognizing the operation of 310, that is, the transfer and stopping the transfer of the first acceleration unit 310 may be performed, and similarly, the second acceleration unit through the second rear end sensor 322 Feedback control for recognizing the operation of 320 , that is, the transfer, and stopping the transfer of the second acceleration unit 320 may be performed.

Hereinafter, with reference to FIG. 7 , when the large cylinders 20 overlap and are transported, the large normal length information obtained by the first and second shear sensors 311 and 321 changes. Explain why.

First, the first acceleration unit 310 includes a first right transfer unit 330 and a first left transfer unit 340 , and the second acceleration unit 320 includes a second right transfer unit 350 and a second left transfer unit 340 . It includes a transfer unit 360 .

Furthermore, the transfer unit 300 includes a first transfer base 304 in which the first and second right transfer units 330 and 340 are located, and the first and second left transfer units 340 and 360 . It further comprises a second transfer base 305 on which it is located.

Although not shown, the large cylinder 20 is transferred along between the first transfer base 304 and the second transfer base 305 . That is, through the first acceleration unit 310, the large cylinder 20 is transferred between the first right transfer unit 330 and the first left transfer unit 340, and similarly, the second acceleration Through the unit 320 , the large cylinder 20 is transferred between the second right transfer unit 350 and the second left transfer unit 360 .

Meanwhile, the first right transfer unit 330 rotates with a driving roll 331 that generates a rotational driving force, the rotational rolls 332 that transmit the driving force and maintain the tension of the transfer belt, and the driving roll 331 . and a first right conveying belt 333 conveyed along the rolls 332 .

Similarly, the first left transfer unit 340 rotates with the driving roll 341 that generates a rotational driving force, the rotational rolls 342 that transmit the driving force and maintain the tension of the transfer belt, and the driving roll 341 . and a first left conveying belt 343 conveyed along the rolls 342 .

In the case of this embodiment, the first right transfer belt 333 and the first left transfer belt 343 have a transfer direction controlled to transfer the large cylinder 20 in the second direction (Y). .

That is, the first right conveying belt 333 is rotated in the clockwise direction as a whole and provides a conveying force in the second direction Y to the large cylinder 20 , and similarly the first left conveying belt 343 . is rotated in a counterclockwise direction as a whole and provides a feeding force in the second direction (Y) to the large cylinder ( 20 ).

However, the transport speed or rotation speed of the first right transport belt 333 and the first left transport belt 343 are different from each other.

In this way, as the transport speeds or rotation speeds of the first right transport belt 333 and the first left transport belt 343 are controlled differently from each other, the first right transport belt 333 and the first left transport belt 333 are controlled differently. If a plurality of large cylinders conveyed between the conveying belts 343 overlap each other, the distance is increased as the plurality of large cylinders are conveyed between the first right conveying belt 333 and the first left conveying belt 343 . it will happen

For example, when two first and second large cylinders are transported, one side of the first large cylinder is in close contact with the first right conveying belt 333 and conveyed at a first speed, but the second large cylinder The other side is in close contact with the first left conveying belt 343 and conveyed at a second speed slower than the first speed, and by this difference in conveying speed, the first and second large barrels overlapping each other in the same size are, As the transfer progresses, the interval increases.

Therefore, the length of the large cylinder measured by the first shear sensor 311 is, when a plurality of the large cylinders overlap, after being transferred along the first acceleration unit 310, the second acceleration unit 320 ), the length is increased and thus the length of the large normal measured by the second shear sensor 321 is changed.

That is, through the difference between the measurement length in the first shear sensor 311 and the measurement length in the second shear sensor 321, it can be determined whether a plurality of the large barrels are transported in an overlapping state with each other. be able to

Thus, when a plurality of large barrels are transported in an overlapping state with each other, it is possible to stop the transport of the transport unit 300 and perform sorting or thinning operations such that the overlapping large barrels are transported one by one, through which Finally, the large cylinders provided to the conversion unit 400 may be maintained one by one.

On the other hand, maintaining the difference in the transport speed of the first right transfer unit 330 and the first left transfer unit 340 in the first acceleration unit 310 may be implemented in the same manner in the second acceleration unit 320 . have.

The second right transfer unit 350 also includes a driving roll 351 that generates a rotational driving force, the rotational rolls 352 that transmit the driving force and maintain the tension of the transfer belt, and the driving roll 351 and the rotational rolls. It includes a second right conveying belt 353 conveyed along the 352 , and similarly, the second left conveying unit 360 also generates a rotational driving force.

On the other hand, although not shown, the outlet unit 500 is further provided with a distance sensor for measuring the distance to the falling position of the large barrel, and by measuring the distance sensor, the large barrel is dropped from the falling position. It can be determined whether the large bin is located in a stopped state for reasons such as not being additionally provided as a sorter.

Thus, if the large barrel is not provided as a sorter and is positioned in a stopped state, the operation of the flat inserter 10 may be stopped.

According to the embodiments of the present invention as described above, by repeatedly measuring the length of the large cylinder to be transported with a plurality of acceleration units, it is possible to easily determine whether a plurality of large cylinders are transported overlapping each other, and this Through this, it is possible to provide the large bins individually as a sorter, making it possible to accurately supply large bins.

In this case, in the transfer unit for transporting the large cylinder, by controlling the conveying speed of the belt conveying the large cylinder in contact with both sides of the large cylinder differently, when a plurality of large cylinders are overlapped and transferred, the entire large cylinder Since the length is induced to increase, it can be easily determined whether a plurality of large barrels are conveyed overlappingly through the length measurement.

In addition, even when a large cylinder is fed from the supply unit to the conveying unit, by controlling the conveying direction of the belt of the input roller part and the conveying direction of the belt of the reverse roller part facing the input roller part differently from each other, a plurality of large cylinders overlap It is possible to easily determine the case of being transported and induce the large barrels to be accurately transported one by one.

In addition, a suction unit is provided to more effectively attach the large barrel to the input roller belt, that is, the input belt, and the suction efficiency sucked through the suction part can be further improved through the through holes formed in the input belt.

In addition, by forming a protrusion on the upper portion of the input roller to support the upper portion of the large cylinder to guide the large cylinder to a standing state, it is possible to solve the problem of effective input or transfer in a tilted state of the large cylinder. In this case, by providing a pressure roller to induce the interruption of the input when the large barrel is pressed, it is possible to effectively process the interruption of the input by sensing that the large barrel is too inclined or the amount is too large to be pushed.

On the other hand, a positioning sensor for sensing the position of the large barrel on the supply space is additionally provided, it is possible to accurately control the operation of the input unit.

Furthermore, it is possible to induce a stable supply to the sorter, while converting the large cylinders transferred vertically through the conversion unit to be conveyed horizontally, and thereby preventing the relatively heavy large cylinders from escaping to the outside due to inertia.
