Referring to fig. 1-4, some embodiments of the present disclosure provide a conveyor apparatus for a carton packing machine for conveying cartons to different packing stations, including a conveyor belt and a clamping device.

The conveyor belt includes a belt body 11 and first clamping portions 12 provided to the belt body 11, and the plurality of first clamping portions 12 are provided at intervals on a conveying surface of the belt body 11 in a conveying direction of the conveyor belt. The clamping device comprises a mounting frame 21 and a second clamping part 22, wherein a plurality of second clamping parts 22 are arranged on the mounting frame 21 at intervals, the mounting frame 21 can be arranged in a reciprocating mode between a first position and a second position, the plurality of second clamping parts 22 avoid conveying spaces required by conveying the strip boxes, and the plurality of second clamping parts 22 and the plurality of first clamping parts 12 form clamping intervals required by clamping the strip boxes in a one-to-one correspondence mode along the conveying direction in the second position, and the size of the clamping intervals is adjustable.

Optionally, the conveyor belt is a synchronous belt. Alternatively, to facilitate rapid replacement of the strip, the head and tail ends of the body 11 of the conveyor belt may be disposed overlapping each other. Alternatively, the first clamping portion 12 is arranged convexly on the conveying surface, and the second clamping portion 22 is arranged convexly on the mounting frame 21, wherein, in the second position, the direction of the protrusion of the second clamping portion 22 is perpendicular to the conveying surface. Alternatively, the first clamping portion 12 and the second clamping portion 22 are plate-shaped, and the second clamping portion 22 is made of a metal material.

Referring to fig. 1 and 2, the conveying device of the carton packing machine of the embodiment of the present disclosure operates as follows.

In the packaging process of the cartons, the cartons are placed in the spaces between two adjacent first clamping portions 12, the cartons can be moved between different packaging stations along the conveying direction on the conveying belt, and different packaging stations are provided with different packaging mechanisms for carrying out different packaging procedures.

When the cartons are conveyed to a position corresponding to the packaging mechanism of a certain packaging station, the conveyor belt is stopped at the position, at this time, the mounting frame 21 moves from the first position to the second position, and the second clamping portions 22 move along with the mounting frame 21 to above the conveying surface and gradually approach the corresponding first clamping portions 12 so as to apply clamping force to the cartons together with the corresponding first clamping portions 12, so that the cartons are kept fixed relative to the packaging mechanism of the packaging station. In the second position, the first 12 and second 22 gripping portions are spaced apart in the conveying direction to a gripping distance, the carton being gripped and the carton being held stationary relative to the packaging station.

The packaging mechanism then performs the corresponding packaging procedure.

When the packaging process is completed, the conveyor belt is started to drive the strip box to move to the next station along the conveying direction, and the mounting frame 21 moves from the second position to the first position so as to avoid the strip box at the upstream from the conveying direction, so that the upstream strip box can smoothly move forward.

After the cartridge and the first clamping portion 12 move in the conveying direction to the next packaging station, the conveyor belt is stopped again, and the first clamping portion 12 and the second clamping portion 22 clamp the cartridge again, performing the next packaging process. And the like until all the packaging procedures are finished.

The spacing of the adjacent two first gripping portions 12 and the spacing of the adjacent two second gripping portions 22 may be determined based on the spacing of the adjacent two packaging stations.

For the adjacent two first holding portions 12, the positional relationship between one first holding portion 12 located upstream and one packaging station located upstream in the conveying direction and the positional relationship between the other first holding portion 12 located downstream and the other packaging station located downstream in the conveying direction may be made uniform. The same applies to two adjacent second clamping portions 22. When the conveyor belt is stopped, two adjacent upstream and downstream cassettes can simultaneously perform two adjacent packaging processes, respectively.

Alternatively, the number of the second clamping portions 22 is the same as the number of the packaging stations, and when the mounting frame 21 moves to the second position, the plurality of second clamping portions 22 correspond to the plurality of packaging stations in position, and the plurality of second clamping portions 22 correspond to the corresponding packaging stations in positional relationship in the conveying direction.

The size of the clamping interval can be determined according to the size of the special-shaped strip box to be clamped.

In the conveying device of the carton packaging machine of the embodiment of the disclosure, as the size of the clamping interval formed by the first clamping part 12 and the second clamping part 22 is adjustable, the conveying device can be used for clamping special-shaped cartons of different specifications, and meets the fixing requirements of the special-shaped cartons of different specifications on a packaging station.

For the conveying device of the carton packing machine in the embodiment of the disclosure, the adjustment of the clamping interval can be realized by adjusting the driving mode of the conveying belt and the clamping device, and also can be realized by a mechanical structure, which is further described in detail below.

In some embodiments, the conveying device further comprises a first motor 3, a second motor 4 and a control device. The first motor 3 is in driving connection with the belt body 11 and is configured to drive the belt body 11 and the first clamping part 12 to move in the conveying direction. The second motor 4 is in driving connection with the mounting frame 21 and is configured to drive the mounting frame 21 to reciprocate between a first position and a second position. The control device is in communication with the first motor 3 and the second motor 4, and is configured to periodically start and stop the first motor 3 and the second motor 4, and adjust the position of the first clamping portion 12 along the conveying direction when the first motor 3 stops, so as to adjust the size of the clamping interval.

Alternatively, referring to fig. 1 and 2, the output shaft of the first motor 3 is in driving connection with the driving wheel of the conveyor belt as a speed change mechanism through another timing belt transmission mechanism. By adjusting the reduction ratio of the speed change mechanism and configuring a corresponding control program in the control device, the distance of the belt 11 moving along the conveying direction is equal to the distance between two adjacent packaging stations for each rotation of the first motor 3.

Alternatively, the control means is configured to start and stop the first motor 3 and the second motor 4 simultaneously.

In the above-described embodiment, the control device is capable of periodically starting and stopping the first motor 3 and the second motor 4. In each period, the displacement time relation of the first motor 3 and the second motor 4 can be determined by a control instruction sent by the control device, and the first motor 3 and the second motor 4 can drive the belt body 11 and the mounting frame 21 to act according to corresponding movement tracks, so that the first clamping part 12 and the second clamping part 22 act in a matched mode. And, by changing the steering of the first motor 3 and the second motor 4, the reversing of the conveyor belt and the clamping device can also be realized.

One of the first motor 3 and the second motor 4 can be regarded as a main shaft of the electronic cam, the other can be regarded as an auxiliary shaft of the electronic cam, and the control device can change the displacement time relation of the first motor 3 and the second motor 4 by drawing different electronic cam curves, so that the position of the first clamping part 12 along the conveying direction when the first motor 3 stops is changed. When the mounting bracket 21 moves to the second position, since the position of the first clamping portion 12 in the conveying direction changes when the first motor 3 is stopped, the positional relationship between the first clamping portion 12 and the second clamping portion 22 in the conveying direction also changes, so that the first clamping portion 12 and the second clamping portion 22 have different clamping intervals.

In the above embodiment, the conveying device can adapt to the packaging procedures of the special-shaped cans with different specifications based on different electronic cam curves by adopting an electronic cam driving mode. Because the adopted mechanical transmission structure is less, the conveying equipment of the embodiment not only occupies less space, can save the internal space of the carton packing machine, but also can reduce vibration and friction and reduce noise generated during operation.

In some embodiments, the first motor 3 is a servo motor, and/or the second motor 4 is a servo motor.

Alternatively, the first motor 3 and the second motor 4 are both servo motors. In the above embodiment, by adopting the servo motor as the driving device of the belt body 11 and the mounting frame 21, the movement of the belt body 11 and the mounting frame 21 can be accurately controlled, not only can the higher rotation speed be achieved, but also the multistage speed change can be realized, and the requirements of different production vehicle speeds can be met.

In some embodiments, the conveying apparatus further comprises a nip detection device disposed on the conveying path of the conveying belt and configured to detect whether the first nip 12 is present at the location. The first motor 3 is a servo motor, and the control device is in communication connection with the clamping part detection device and is configured to determine whether to adjust the zero position of the encoder of the first motor 3 according to the time interval when the clamping part detection device detects that the first clamping part 12 and the first motor 3 are switched from the start state to the stop state.

Optionally, the clamping portion detecting device is a photodetector. Optionally, the clamping part detection device is arranged at the side of the conveying belt.

The conveying device of the above embodiment can eliminate the accumulated error of the encoder based on the detection signal of the nip detecting device, as follows.

Referring to fig. 3, when a certain first clamping portion 12 moves to a position where a clamping portion detecting device is located along the conveying direction, the first clamping portion 12 triggers the clamping portion detecting device, the clamping portion detecting device detects that the first clamping portion 12 exists to generate signal change, and the clamping portion detecting device sends a switching value to the control device. In an ideal state where the encoder of the first motor 3 does not generate an error, the time interval between the timing at which the clamp detection device is triggered, that is, the timing at which the switching value rising edge is located, and the timing at which the first clamp 12 is switched to the stopped state with the belt 11 should be a fixed value. For example, if the position of the clamping portion detecting device coincides with the stop position of the first clamping portion 12 in each operation cycle in the conveying direction, after the first motor 3 operates for one cycle, the clamping portion detecting device is triggered by the first clamping portion 12, and at the same time, the first clamping portion 12 is switched to the stop state along with the belt 11, that is, the time interval is 0.

If the actual time interval does not deviate from the fixed value by more than the allowable range, it is indicated that the accumulated error of the encoder of the first motor 3 does not exceed the allowable range. If the deviation between the actual time interval and the fixed value exceeds the allowable range, which indicates that the accumulated error of the encoder of the first motor 3 also exceeds the allowable range, the control device needs to adjust the zero position of the encoder, and can eliminate the accumulated error of the encoder of the first motor 3 by sending a control command for reacquiring the zero position to the encoder and taking the encoder value corresponding to the moment when the clamping part detecting device is triggered as the zero position of the encoder.

In some embodiments, the mounting bracket 21 is swingably disposed between a first position and a second position.

In some embodiments, referring to fig. 1 and 2, the conveying apparatus further includes a second motor 4 and a screw pair 5, the second motor 4 is in driving connection with the screw portion of the screw pair 5 and configured to drive the screw portion to rotate, the clamping device further includes a link 23 and at least two cranks 24, the link 23 is mounted to the nut portion of the screw pair 5, and the mounting bracket 21, the link 23 and the at least two cranks 24 constitute a parallelogram mechanism so that the mounting bracket 21 swings with the rotation of the second motor 4.

In the above embodiment, two ends of each crank 24 are hinged to the mounting frame 21 and the connecting rod 23 respectively, the second motor 4 can drive the screw rod portion of the screw rod pair 5 to rotate, the connecting rod 23 moves linearly along with the nut portion of the screw rod pair 5, and the connecting rod 23 drives the two cranks 24 to swing, so that the mounting frame 21 is driven to swing between the first position and the second position.

Alternatively, the nut portion of the screw pair 5 is reciprocatingly provided in the conveying direction, so that the link 23 can reciprocate in the conveying direction, and further the mount 21 and the second clamp portion 22 can swing up and down with respect to the conveying surface of the conveying belt.

In some embodiments, the mounting position of the second clamping portion 22 on the mounting frame 21 is adjustable to adjust the size of the clamping interval.

The conveying device of the above embodiment can adjust the size of the clamping interval by adjusting the position of the second clamping portion 22 relative to the mounting frame 21, that is, the size of the clamping interval is adjusted by the mechanical structure of the second clamping portion 22.

In some embodiments, referring to fig. 4, the second clamping portion 22 is provided with a connection hole 220, the clamping device includes a threaded connection member 25, and the threaded connection member 25 is cooperatively connected with the mounting frame 21 through the connection hole 220 to fasten the second clamping portion 22 to the mounting frame 21, and the connection hole 220 is a long hole.

Alternatively, the length direction of the connection hole 220 is perpendicular to the clamping surface of the second clamping portion 22.

In the above embodiment, the second clamping portion 22 is detachably connected to the mounting bracket 21 through the screw connector 25, and by providing the connecting hole 220 as a long hole, the fastening position of the second clamping portion 22 with respect to the mounting bracket 21 can be adjusted along the length direction of the connecting hole 220, thereby functioning to adjust the size of the clamping interval.

In some embodiments, referring to fig. 1, the conveyor comprises two synchronously movable conveyor belts arranged side by side at a distance from each other perpendicular to the conveying direction, and in the second position the mounting 21 is located between the two conveyor belts and forms a clamping distance together with the first clamping portions 12 of the two conveyor belts.

In the above embodiment, when the cans are conveyed to the position corresponding to the packaging mechanism of a certain packaging station, the two first clamping portions 12 of the two conveying belts and the second clamping portion 22 can act on the cans together, so as to facilitate more stable clamping of the cans.
