[0002] In the packaging production of cigarette packs, the automatic feeding equipment for forming cigarette boxes is fed alternately by two paper trays on the left and right. During operation, workers transport the paper tray full of paper materials to the yellow line feeding area marked on the ground. However, since there is no limit detection device in the feeding area, workers sometimes do not control the force or distance properly when feeding, which may cause the full paper tray to collide with the guardrail of the equipment, which may cause damage to the paper material on the paper tray and shift its position, thereby affecting the processing quality of the product and the gripping of the paper material, and also causing certain damage to the guardrail. In addition, after the equipment loses power due to factory shutdown or other reasons, it is impossible to determine whether there is a paper tray in the feeding area. It is necessary to take pictures multiple times through the visual camera on the robotic arm to analyze and determine the situation in the feeding area, which will slow down the production rhythm. Summary of the invention

[0003] In view of the shortcomings of the prior art described above, the purpose of the utility model is to provide a paper tray limit detection device for solving the problems in the prior art that workers are prone to collision with loading equipment when transporting paper trays for feeding, and it is difficult to identify whether there are paper trays in the feeding area.

[0005] Preferably, the limit baffle is provided with two opening slots, which are respectively a first opening slot and a second opening slot, and the first opening slot and the second opening slot are respectively located at the left and right ends of the limit baffle; the trigger sensors are provided with two, which are respectively a first trigger sensor and a second trigger sensor, wherein the first trigger sensor is arranged at the first opening slot, and the second trigger sensor is arranged at the second opening slot.

[0006] Preferably, it also includes a hydraulic buffer, which is fixedly arranged on the limit baffle and located at the opening groove, and one end of the hydraulic buffer protrudes from the opening groove to a certain distance from the limit surface of the limit baffle.

[0007] Preferably, a protective cover is further provided on the limit baffle, and the trigger sensor and the hydraulic buffer are both located inside the protective cover, and the protective cover is used to protect the trigger sensor and the hydraulic buffer.

[0008] Preferably, the trigger sensor and the hydraulic buffer are fixedly arranged on the limit baffle via a mounting plate.

[0010] Preferably, the elastic element is a spring.

[0011] As described above, the paper support limit detection device of the utility model has the following beneficial effects: during feeding, when the paper support is transported to the set position of the feeding area, one side of the paper support will fit with the limit surface of the limit baffle, that is, the limit baffle can mechanically limit the paper support that has been transported to the position, thereby preventing the paper support from colliding with the feeding equipment due to improper force control by the worker; at the same time, since a trigger sensor is provided on the limit baffle, when the paper support is transported to the set position of the feeding area, that is, when it fits with the limit surface of the limit baffle, the paper support will compress the trigger probe of the trigger sensor, so that the trigger sensor will detect the existence of the paper support, and when the paper support is lifted out of the feeding area, the trigger probe of the trigger sensor returns to its original position, and the trigger sensor will detect that there is no paper support in the feeding area for feeding, so that the trigger sensor will send an alarm signal to the control system of the feeding equipment to remind the staff to feed in time. Therefore, compared with the prior art, the paper support limit detection device of the utility model avoids the problem of damage to materials and equipment caused by staff members' feeding errors, and also facilitates the rapid positioning of the paper support and the identification and detection of the paper support in the feeding area, thereby improving production operation efficiency.

In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0040] The utility model provides a paper support limit detection device, such as Figure 1 As shown, the paper support limit detection device includes a limit baffle 10 and a trigger sensor, wherein the limit baffle 10 is used to be set at a set position in the material feeding area, an opening groove is provided on the limit baffle 10, and the trigger sensor is fixedly set on the limit baffle 10 and is located at the opening groove. Specifically, the trigger sensor includes a detection module and a trigger probe communicatively connected to the detection module, and an elastic element is clamped between the trigger probe and the detection module, and the trigger probe protrudes from the opening groove on the limit baffle 10 by a certain distance from the limit surface 101 of the limit baffle 10.

[0041] When the paper support limit detection device of the utility model is used, Figure 3As shown, when a worker pushes a paper tray 100 full of paper materials to feed the material to the feeding area, since a limit baffle 10 is provided at the setting position of the feeding area, the limit baffle 10 can mechanically limit the paper tray 100 that has been delivered to the position, that is, when the paper tray 100 is delivered to the setting position of the feeding area, one side of the paper tray 100 will fit with the limit surface 101 of the limit baffle 10, thereby preventing the worker from colliding with the feeding equipment due to improper force control; at the same time, since a trigger sensor is provided on the limit baffle 10 (the trigger sensor can be When the paper tray 100 is delivered to the set position of the feeding area, that is, it is in contact with the limit surface 101 of the limit baffle 100, the paper tray 100 will compress the trigger probe of the trigger sensor, so that the trigger sensor will detect the existence of the paper tray 100. When the paper tray 100 is lifted out of the feeding area, the trigger probe of the trigger sensor returns to its original position, and the trigger sensor will detect that there is no paper tray in the feeding area for feeding, so that the trigger sensor will send an alarm signal to the control system of the feeding equipment to remind the staff to feed in time. Therefore, compared with the prior art, the paper tray limit detection device of the utility model avoids the problem of damage to materials and equipment caused by staff when feeding errors occur, and also facilitates the rapid positioning of the paper tray and the identification and detection of the paper tray in the feeding area, thereby improving the production and operation efficiency.

[0042] Specifically, in this embodiment, the elastic element between the trigger probe and the detection module is a spring.

[0043] Furthermore, in order to make the position of the paper tray 100 placed in the feeding area more accurate, so that the feeding device can grab the paper on the paper tray 100 more efficiently, that is, easier to grab, preferably, as Figure 1 and Figure 2As shown, in the present embodiment, the limit baffle 10 is provided with two opening grooves, namely, the two opening grooves are respectively a first opening groove 11 and a second opening groove 12, and the first opening groove 11 and the second opening groove 12 are respectively located at the left and right ends of the limit baffle 10; correspondingly, in the present embodiment, two trigger sensors are provided, and the two trigger sensors are respectively a first trigger sensor 21 and a second trigger sensor 22, wherein the first trigger sensor 21 is arranged at the first opening groove 11, and the second trigger sensor 22 is arranged at the second opening groove 12. That is, the first trigger sensor 21 includes a first detection module 212 and a first trigger probe 211, and a first elastic element (not shown in the figure) is arranged between the first trigger probe 211 and the first detection module 212, and the first trigger probe 211 protrudes outward from the first opening groove 11 by a certain distance from the limiting surface 101 of the limiting baffle 10; the second trigger sensor 22 includes a second detection module 222 and a second trigger probe 221, and a second elastic element is arranged between the second trigger probe 221 and the second detection module 222, and the second trigger probe 221 protrudes outward from the second opening groove 12 by a certain distance from the limiting surface 101 of the limiting baffle 10. Through this structural design, that is, the first trigger sensor 21 and the second trigger sensor 22 are respectively arranged at the left and right ends of the limit baffle 10. When the paper tray 100 is transported to the feeding area, if only the first trigger sensor 21 or the second trigger sensor 22 detects the trigger signal, it means that there is a deviation in the placement of the paper tray 100 in the left and right directions, thereby reminding the staff to put the paper tray 100 in place in the left and right directions again, so as to facilitate the feeding equipment to grab the paper material on the paper tray.

[0044] Furthermore, in order to prevent the impact force generated by the rigid collision between the paper support 100 and the limiting baffle 10 from causing the paper materials on the paper support 100 to shake when the limiting baffle 10 is limiting the paper support 100, thereby causing the position of the paper materials stacked on the paper support 100 to shift, thereby affecting the feeding device's grasping of the paper materials. Preferably, in this embodiment, a hydraulic buffer is also provided on the limiting baffle 10, and the hydraulic buffer is also provided at the opening groove of the limiting baffle 10, and one end of the hydraulic buffer protrudes from the opening groove to a certain distance from the limiting surface 101 of the limiting baffle.

Through this structural design, that is, through the setting of the first long hole 4120, the installation position of the first mounting plate 41 on the limiting baffle 10 can be adjusted, that is, the setting position of the first trigger sensor 21 and the first hydraulic buffer 31 relative to the limiting baffle can be adjusted, so as to be suitable for different incoming material requirements.

[0047] Specifically, in this embodiment, the structure of the second mounting plate 42 is the same as that of the first mounting plate 41 , so it will not be described in detail herein.

[0048] Furthermore, in order to prevent the trigger sensor and the hydraulic buffer from being squeezed and collided during the operation and to increase the service life of the two, preferably, a protective cover is also provided on the limit baffle, and the trigger sensor and the hydraulic buffer are both located in the protective cover, and the protective cover is used to protect the trigger sensor and the hydraulic buffer. Figure 1As shown, a first protective cover 51 is provided at the position of the first opening groove 11 of the limit baffle 10, and the first protective cover 51 is used to protect the first trigger sensor 21 and the first hydraulic buffer 31. A second protective cover 52 is provided at the position of the second opening groove 12 on the limit baffle 10, and the second protective cover 52 is used to protect the second trigger sensor 22 and the second hydraulic buffer 32.
