Technical Field

[0001] This utility model belongs to the field of carton forming technology, and relates to a feeding device, particularly a feeding device with back-sweeping function. Background Technology

[0002] Packaging boxes are generally used to package items of various sizes, and their materials typically include cardboard and plastic. Usually, the design of the packaging box is printed onto the surface of the cardboard, creases are created by pressing the folds of the box, excess cardboard is trimmed, and then the boxes are assembled.

[0003] As is well known, to improve the appearance of packaging boxes, the design is usually printed on the outer surface of the cardboard, while the creases are located on the inner surface. After the cardboard is creased, it needs to be flipped 180° using a flipping mechanism so that the outer surface is facing up and the inner surface is facing down, thus preventing damage to the design during cutting. However, the flipped cardboard needs to be scanned and positioned again, which is not only time-consuming and inefficient, but also requires an additional flipping mechanism, increasing the complexity of the equipment and production costs. Utility Model Content

[0007] The back scanning module is located below the paperboard output end. The back scanning module includes a back scanning bracket connected to the frame, and a scanning camera that can reciprocate along the length of the back scanning bracket is set on the back scanning bracket. The scanning camera scans multiple scanning points to form the cutting area of ​​the paperboard.

[0008] In the aforementioned feeding device with back scanning function, a back scanning drive structure for driving the scanning camera to reciprocate is provided on the back scanning bracket. The back scanning drive structure includes a back scanning motor, a reducer connected to the output end of the back scanning motor, and a pulley structure connected to the reducer. The pulley structure includes a driving pulley, a driven pulley, and a synchronous belt connecting the driving pulley and the driven pulley. The scanning camera is connected to the synchronous belt through the back scanning bracket.

[0009] In the aforementioned feeding device with back-sweeping function, the two sides of the open end of the back-sweeping bracket are respectively connected to the two sides of the feeding frame.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] like Figures 1 to 4 As shown, the present invention provides a feeding device with a back-sweeping function, comprising:

[0032] The machine frame 100 is provided with a feeding channel, the two ends of which are a cardboard feeding end 110 and a cardboard discharging end 120, wherein the inner surface of the cardboard located in the feeding channel is exposed with its surface facing upwards and the outer surface of the cardboard is hidden with its surface facing downwards, and multiple scanning points are provided on the outer surface of the cardboard.

[0033] The back scan module 200 is located below the cardboard output end 120. The back scan module 200 includes a back scan bracket 210 connected to the frame 100, and a scanning camera 220 that can reciprocate along the length of the back scan bracket 210 is provided on the back scan bracket 210. The scanning camera 220 scans multiple scanning points to form the cutting area of ​​the cardboard.

[0034] It is worth mentioning that before the cardboard is fed, multiple scanning points are marked on the outer surface of the cardboard, and these scanning points are distributed at various corners of the cardboard. The distance between each scanning point and the adjacent two sides of the cardboard is a first preset distance and a second preset distance, respectively. When the cardboard is conveyed forward along the feeding channel, the front edge of the cardboard passes through the cardboard discharge end 120 and extends outward for a certain distance before stopping. The length of this distance is just enough to allow the scanning camera 220 to scan all the scanning points on the front end of the cardboard during its reciprocating movement. Then the cardboard continues to be conveyed forward and stops after moving a corresponding distance. The scanning camera 220 scans all the scanning points on the rear end of the cardboard through its reciprocating movement. Based on the coordinates of all the scanning points on the front end and the rear end of the cardboard, the cutting area of ​​the cardboard is drawn, which facilitates the precise cutting of the cardboard.

[0035] It is further pointed out that although the position of each scanning point on the cardboard is known in advance, when the cardboard is conveyed in the feeding channel, the position of the cardboard in the feeding channel is unpredictable, which makes the coordinates of each scanning point on the cardboard uncertain. However, the scanning module can accurately collect the position of each scanning point on the cardboard in the feeding channel and form the corresponding coordinates, which are then drawn into the cutting area of ​​the cardboard.

[0036] In addition, the reason for knowing the distance between each scanning point and its adjacent two edges is to control the distance the front end of the cardboard extends, and how far the cardboard should continue to move after the front end is scanned before it needs to stop again, so as to ensure that all scanning points on the front end and the back end of the cardboard can be scanned.

[0037] This utility model provides a feeding device with a back-scanning function, which can accurately locate the cutting area of ​​the cardboard without flipping it, thereby improving work efficiency and reducing production costs.

[0038] More preferably, the back scan bracket 210 is provided with a back scan drive structure 230 for driving the scanning camera 220 to reciprocate. The back scan drive structure 230 includes a back scan motor 231, a reducer 232 connected to the output end of the back scan motor 231, and a pulley structure connected to the reducer 232. The pulley structure includes a driving pulley 233, a driven pulley 234, and a synchronous belt 235 connecting the driving pulley 233 and the driven pulley 234. The scanning camera 220 is connected to the synchronous belt 235 through the back scan support 260.

[0039] It is worth mentioning that the back sweeping bracket 210 is arranged in a C-shape. The two sides of the open end of the back sweeping bracket 210 are respectively connected to the two sides of the feed frame 100. The back sweeping drive structure 230 is connected to the closed end of the back sweeping bracket 210. Two wheel seats are respectively provided at both ends of the closed end of the back sweeping bracket 210, namely the active pulley seat 236 and the driven pulley seat 237. The active pulley 233 is installed in the active pulley seat 236 through the active pulley shaft 238, and the driven pulley 234 is installed in the driven pulley seat 237 through the driven pulley shaft 239.

[0040] More preferably, the driven pulley seat 237 is provided with an adjustment structure 240, and the adjustment structure 240 includes adjustment blocks 241 disposed on both sides of the driven pulley seat 237, and an adjustment rod 242 connected to the corresponding end of the driven pulley shaft 239 is inserted into each adjustment block 241, and an adjustment nut 243 is screwed onto the adjustment rod 242. By rotating the adjustment nut 243, the driven pulley shaft 239 is moved along the axial direction of the adjustment rod 242, changing the relative distance between the driven pulley shaft 239 and the driving pulley shaft 238, thereby achieving the tensioning of the synchronous belt 235.

[0041] Preferably, a sliding structure 250 is provided between the back scan support 260 and the closed end of the back scan bracket 210, and the sliding structure 250 includes a slide rail 251 connected to the closed end of the back scan bracket 210 and a slider 252 connected to the back scan support 260. The sliding cooperation between the slider 252 and the slide rail 251 ensures the straightness of the scanning camera 220 during the reciprocating movement.

[0042] More preferably, an anti-collision block 253 is provided at each end of the slide rail 251, and the anti-collision block 253 is connected to the closed end of the back scan bracket 210 by fasteners.

[0043] It is worth mentioning that the anti-collision block 253 is made of flexible material. By setting an anti-collision block 253 at each end of the slide rail 251, the movement stroke of the back sweeper support 260 is controlled to avoid collision between the back sweeper support 260 and the active pulley seat 236 or the driven pulley seat 237. Moreover, since the anti-collision block 253 is made of flexible material, it can offset the impact force generated when the back sweeper support 260 collides with the anti-collision block 253 during movement, thus protecting the back sweeper support 260.

[0044] Preferably, the back scan support 260 includes a back scan lower support 261 and a back scan upper support 262 stacked on each other, and a timing belt fixing block 263 connected to the timing belt 235 is provided on the back scan lower support 261, and a camera fixing seat 264 for fixing the scanning camera 220 is provided on the back scan upper support 262. The slider 252 is connected to the back scan lower support 261, and the camera fixing seat 264 is L-shaped.

[0045] Furthermore, the scanning camera 220 is movably connected to the camera mounting base 264 via the housing 265, and the housing 265 can move vertically in a direction close to or away from the cardboard output end 120. An adjustment hole 2641 is provided on the camera mounting base 264, and the adjustment hole 2641 is an elongated hole.

[0046] In this embodiment, by providing an adjustment hole 2641 in the camera mounting base 264, the scanning camera 220 can move up and down in the vertical direction, so that the scanning camera 220 can clearly scan the scanning points on the cardboard, thereby drawing a precise cutting area.

[0047] Preferably, an optical coupler assembly 266 is provided on the back scan support 261, and a support plate 211 is provided on the back scan bracket 210. When the optical coupler assembly 266 and the support plate 211 are aligned, the scanning camera 220 returns to the origin.

[0048] Preferably, a power module 270 is also provided between the camera mount 264 and the back scan upper support 262, and the power module 270 is mounted on the back scan upper support 262, wherein the camera mount 264 is connected to the output end of the power module 270.

[0049] It is worth mentioning that the scanning camera 220 moves along the Y-axis through the back scan drive structure 230 and moves along the X-axis through the power module 270. The movement of the scanning camera 220 along the X-axis is suitable for the debugging stage. When the debugging is completed and the camera enters the working state, the scanning camera 220 only moves back and forth along the Y-axis.
