Description

Technical Field

[0001] The present application relates to the technical field of photo paper roll transportation, and in particular to a device for transporting photo paper rolls. Background Art

[0002] Photographic paper, also known as light-sensitive printing paper, photographic paper and printing paper, is divided into three categories according to the way it outputs images. They are traditional silver halide printing paper, inkjet printing paper and printing paper. The manufacturing process of photo paper rolls first produces photo paper, then wraps the photo paper onto a paper core tube through a rewinder to form a photo paper roll, which also needs to be packaged in plastic film.

[0003] The wrapped single photo paper roll needs to be wrapped as a whole in a plastic roll to prevent the photo paper from being contaminated or damaged during shipment, thereby reducing economic losses.

[0004] Most existing transfer devices use robotic arms to clamp the photo paper rolls or perform manual transportation. When using the robotic arm clamping method, the photo paper rolls usually need to be wrapped in plastic film. The plastic film is easy to wear and has a certain degree of stickiness. During transportation, the plastic film may fall off due to excessive force, causing the photo paper roll to be damaged or adhere to the clamping device, which is difficult to clean and affects the subsequent transportation of the photo paper rolls. Summary of the Invention

[0005] The present application provides a transfer device for a photo paper roll, which can solve the problem that during transportation of the existing photo paper roll, the plastic film on the outside of the photo paper roll may fall off due to the strong force of the clamping device, causing the photo paper roll to be damaged or adhere to the clamping device, making it difficult to clean.

[0006] The technical solution of the present application is as follows: A device for transferring a photo paper roll, comprising: A stand, the stand being placed vertically, the upper end of the stand being connected to a drive device, and a retractable carrying rod assembly being provided on one side of the lower end of the stand, the carrying rod assembly having one end that is expandable and deformable, the carrying rod assembly extending into a drum of a photo paper roll and expanding and deforming to grasp and fix the photo paper roll, and the carrying rod assembly retracting and disengaging from the drum of the photo paper roll to release the photo paper roll; A horizontal frame is horizontally arranged on the vertical frame and is arranged at 90 degrees to the vertical frame. One end of the horizontal frame is provided with a guard plate assembly that can be opened and closed and flipped. The guard plate assembly is used to protect the photo paper roll while keeping the photo paper roll stable on the carrying rod assembly.

[0007] By adopting the above solution, a vertical frame equipped with a carrying rod assembly is used. When the photo paper roll needs to be transported, one end of the carrying rod assembly can expand and press against the drum of the photo paper roll, so that the entire photo paper roll can move onto the carrying rod assembly as the carrying rod assembly retracts, thereby reducing damage to the photo paper roll. At the same time, a horizontal frame that can be flipped open and closed is provided. The guard plate assembly at one end of the horizontal frame can not only protect the photo paper roll from bumps during transportation, but also assist the carrying rod assembly to limit it on the carrying rod assembly. When the carrying rod assembly needs to be lowered, the expansion degree of one end of the carrying rod assembly is cancelled, so that the photo paper roll automatically falls, which improves the placement stability of the photo paper roll while reducing manpower input.

[0008] In one embodiment of the present application, the carrier bar assembly includes: A conical cylinder, one end of which is vertically mounted on the stand and the other end of which is provided with an opening; A telescopic rod is coaxially arranged inside the conical tube, and a cylinder is provided on the side of the stand facing away from the conical tube, wherein the drive shaft of the cylinder is fixedly connected to the telescopic rod; An inflatable shaft, one end of which is coaxially fixed to the telescopic rod, and the other end of which is driven by the telescopic rod to extend or retract into the conical cylinder.

[0009] By adopting the above solution, by providing the conical cylinder and the inflatable shaft, when it is necessary to grab the photo paper roll, the telescopic rod is used to drive one end of the inflatable shaft to extend into the photo paper roll, and the expansion of one end of the inflatable shaft is used to limit the photo paper roll in one direction, and the telescopic rod is used again to drive the inflatable shaft to retract, so that the photo paper roll can climb along the conical cylinder until the photo paper roll is stuck outside the conical cylinder and remains stable, thereby achieving stable assembly of the photo paper roll. At the same time, when unloading is required, it is only necessary to close the inflatable shaft so that one end of it no longer expands. Since the photo paper roll loses the cooperation limit with one end of the inflatable shaft, it can automatically slide down in the opposite direction along the conical cylinder under the action of its own gravity, without the need for human intervention, thereby achieving convenient unloading.

[0010] In one embodiment of the present application, one end of the cross frame is rotatably connected to the guard plate assembly via a rotating shaft, and a driving assembly is installed on the cross frame, which can push the guard plate assembly to flip over to move away from the carrying rod assembly and scratch the plastic film debris on the guard plate assembly. A torsion spring is provided on the outside of the rotating shaft for driving the guard plate assembly to return to the center position, and both ends of the torsion spring are respectively connected and fixed to the guard plate assembly and the cross frame.

[0011] By adopting the above solution, since the guard plate assembly can be flipped open and closed, when it is necessary to grab the photo paper roll, the guard plate assembly is pushed away from the carrying rod assembly by using the driving assembly. At this time, the driving assembly can push the guard plate assembly away and also scrape off the plastic film debris on the side of the guard plate assembly close to the carrying rod assembly, which is convenient for loading the photo paper roll and can also easily clean the plastic film debris remaining on the guard plate assembly. At the same time, the torsion spring can ensure that when the guard plate assembly is not pushed by the driving assembly, the carrying rod assembly can automatically return to the center and press against the photo paper roll to keep the photo paper roll stable on the carrying rod.

[0012] In one embodiment of the present application, the guard plate assembly includes: A plate body, wherein one end of the plate body is provided with a rectangular opening for the cross frame to pass through, and one end of the plate body is rotatably connected to the cross frame at the rectangular opening via a rotating shaft; The stopper is arranged on the other end of the plate body and is used for resisting the photo paper roll when the plate body is close to the carrying rod assembly.

[0013] By adopting the above solution, the flippable plate is used so that when the plate is rotated close to the carrying rod assembly, it can press against one side of the photo paper roll, thereby providing partial support when the photo paper roll is fixed on the carrying rod assembly.

[0014] In one embodiment of the present application, the blocking member includes: A connecting frame, wherein a cavity is provided inside the connecting frame, and a plurality of vertically arranged and mutually spaced cylindrical grooves are opened at one end of the plate body, and a rotating roller is rotatably connected to the inner wall of the bottom end of the cylindrical groove, and the upper end of the rotating roller extends into the cavity and is rotatably connected to the connecting frame; An annular ratchet groove is provided on the upper end of the rotating roller along its circumference, and a ratchet pawl adapted to the annular ratchet groove is provided on the inner wall of the cavity. The ratchet pawl is rotatably assembled on the inner wall of the cavity.

[0015] By adopting the above solution, using a rotating roller that can rotate in one direction, when grabbing the photo paper roll for loading, even if the rotating roller comes into contact with the photo paper roll, it will rotate inside the cylindrical groove, thereby reducing the friction between the photo paper roll and the rotating roller. When the auxiliary carrying rod assembly is needed to fix the photo paper roll later, the rotating roller cannot rotate in the opposite direction due to the engagement between the pawl and the annular ratchet groove, so that the stopper can provide a certain support force on the side of the photo paper roll.

[0016] In one embodiment of the present application, the driving assembly includes an electric push rod, which is fixedly assembled on the cross frame, and the driving shaft of the electric push rod is fixedly connected to a scraper.

[0017] By adopting the above solution, a scraper is set on the driving shaft of the electric push rod. When the electric push rod drives the guard plate assembly to flip, the scraper can scrape off the plastic film debris adhered to the plate body while pushing the guard plate assembly to flip.

[0018] In one embodiment of the present application, an arc segment is fixedly assembled at one end of the cross frame, the cross-section of the arc segment is semicircular, and rubber strips are arranged at intervals on the arc segment. A connecting strip is assembled on the side of one end of the plate body facing away from the baffle, and one end of the connecting strip extends to contact the surface of the arc segment.

[0019] By adopting the above solution, one end of the plate body is set to an arc segment with a semicircular cross-section, so that when the plate body is pushed and deflected by the driving component to avoid movement interference between the photo paper roll and the plate body, the connecting strip on the plate body can move circumferentially around the arc segment. When the connecting strip passes through the rubber strip, it squeezes the rubber strip. During the process of being squeezed and rebounding, the rubber strip vibrates continuously, and the vibration is transmitted to the carrying rod assembly, so that the photo paper roll can be quickly separated from the carrying rod assembly, thereby improving the unloading efficiency.

[0020] In one embodiment of the present application, a plurality of annular rubber rings are spaced apart on the outside of the inflatable shaft, and a plurality of annular grooves spaced apart are formed on the inner wall of the opening at one end of the conical cylinder.

[0021] By adopting the above solution, a plurality of annular rubber rings are arranged at intervals on the outside of the inflatable shaft. When the inflatable shaft retracts into the inside of the conical cylinder, the photo paper roll can slide along the carrying rod assembly for unloading. When the rubber rings on the outside of the inflatable shaft pass through the annular groove at the opening, they can be continuously squeezed and rebounded, thereby causing the carrying rod assembly to vibrate further and increasing the speed of sliding and unloading of the photo paper roll.

[0022] In one embodiment of the present application, a plurality of triangular reinforcement rings are fixedly installed inside the conical cylinder along its own length direction, the telescopic rod passes through the triangular reinforcement rings, and a plurality of elastic rings are sleeved on the outside of the telescopic rod, and the diameter of the elastic ring is larger than the diameter of the inscribed circle of the triangular reinforcement ring.

[0023] By adopting the above solution, by arranging multiple tripod reinforcement rings inside the conical tube, the structural strength of the conical tube can be further improved. At the same time, when the telescopic rod drives the inflatable shaft to retract, the elastic ring outside the telescopic rod is continuously squeezed by the triangular reinforcement ring and elastically deformed when following the movement of the telescopic rod, thereby further intensifying the vibration effect of the entire carrying rod assembly and facilitating the unloading of photo paper rolls.

[0024] In one embodiment of the present application, the stand comprises: A connecting plate, the upper end of which is connected and fixed to the driving device, and the lower end of which is provided with a connecting column; The frame body has a connecting piece at its upper end, a columnar cavity is provided inside the connecting piece, the connecting piece is hinged to the connecting piece at the columnar cavity, and a fastening bolt is screwed on the connecting piece.

[0025] By adopting the above solution, by setting up a stand that can deflect an angle, when it is necessary to adjust the deflection angle of the carrying rod in the vertical direction, the angle between the frame and the connecting plate is adjusted, and the angle is fixed with fastening bolts. When the carrying rod assembly undergoes slight deformation due to long-term use, the angle can be fine-tuned to make it easier to insert the photo paper roll and grab it for transportation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a conical tube and a telescopic rod, the telescopic rod drives the air shaft to expand and contract inside the conical tube, and at the same time controls the expansion and deformation of the air shaft, so that it can drive the photo paper roll to move. Utilizing the shape characteristics of the outer surface of the conical tube, the photo paper roll is automatically limited and fixed to the conical tube after being subjected to traction on one side. When the air shaft releases the photo paper roll, due to the lower height of one end of the conical tube, the photo paper roll will automatically slide down along the conical tube, thereby achieving the purpose of automatic unloading.

[0027] 2. By setting up a guard plate assembly and a driving device, the driving device can drive the scraper bar to push the guard plate assembly to flip, thereby avoiding spatial interference between the guard plate assembly and the photo paper roll. At the same time, the scraper bar can also scratch the plastic film debris on the plate body, causing the plastic film debris to fall off the plate surface, avoiding the trouble of manual cleaning of the guard plate assembly. At the same time, the guard plate assembly can also be used to assist in clamping the photo paper roll, thereby improving the stability of the photo paper roll on the carrying rod assembly.

[0028] 3. By configuring one end of the plate as an arc segment with a semicircular cross-section, and providing a connecting strip on one side of the plate that can rotate around the arc segment as the plate flips, the connecting strip sequentially squeezes the rubber strips during rotation. The vibration generated by the rebound of the rubber sleeve can be transmitted to the carrying rod assembly, allowing the photo paper roll to be detached from the conical cylinder more quickly during unloading without affecting the flipping and opening of the plate.

[0029] 4. Multiple elastic rings are installed on the telescopic rod through the triangular reinforcement ring. As the elastic ring on the outside of the telescopic rod moves within the triangular reinforcement ring, it is continuously squeezed by the triangular reinforcement ring, causing itself to deform. The vibration generated by the rebound after deformation is transmitted to the conical tube, which also speeds up the unloading of photo paper rolls and improves the structural strength of the conical tube without affecting the retraction of the inflation shaft.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-10 The transfer device for a photo paper roll provided in the present application is described in further detail.

[0033] A device for transferring a photo paper roll provided in an embodiment of the present application includes a vertical frame 1 and a horizontal frame 3 .

[0034] See also Figure 1 The stand 1 is placed vertically, the upper end of the stand 1 is connected to the driving device, and a retractable carrying rod assembly 2 is provided on one side of the lower end of the stand 1. One end of the carrying rod assembly 2 can expand and deform. One end of the carrying rod assembly 2 extends into the winding drum 51 of the photo paper roll 5 and expands and deforms to grab and fix the photo paper roll 5. One end of the carrying rod assembly 2 retracts and detaches from the winding drum 51 of the photo paper roll 5 to release the photo paper roll 5. The horizontal frame 3 is horizontally arranged on the vertical frame 1 and is arranged at 90 degrees to the vertical frame 1. A reversible guard plate assembly 4 is provided at one end of the horizontal frame 3. The guard plate assembly 4 is used to protect the photo paper roll 5 while stabilizing the photo paper roll 5 on the carrying rod assembly 2. The carrying rod assembly 2 that can expand and deform is inserted into the winding drum 51 of the photo paper roll 5, so that the photo paper roll 5 can be grasped and unloaded quickly and efficiently, and the reversible guard plate assembly 4 is used to protect the photo paper roll 5 during its movement.

[0035] The driving device may be a combination of multiple sets of linear motion modules in different directions, and the specific assembly and combination method thereof is a conventional technology in this field, so it will not be described in detail here.

[0036] See also Figure 2 The carrying rod assembly 2 includes: a conical cylinder 21, a telescopic rod 22 and an inflatable shaft 23. One end of the conical cylinder 21 is vertically assembled on the stand 1, and the other end is provided with an opening. The telescopic rod 22 is coaxially arranged inside the conical cylinder 21. The stand 1 is provided with a cylinder 24 on the side away from the conical cylinder 21. The driving shaft of the cylinder 24 is connected and fixed to the telescopic rod 22. One end of the inflatable shaft 23 is coaxially fixed to the telescopic rod 22, and the other end is extended or retracted into the conical cylinder 21 under the drive of the telescopic rod 22. One end of the inflatable shaft 23 expands to perform a one-way limit engagement on the photo paper roll 5 and cooperates with the conical cylinder 21 until the photo paper roll 5 is stuck on the outside of the conical cylinder 21 and remains stable, thereby achieving stable assembly of the photo paper roll 5. At the same time, when unloading is required, the inflatable shaft 23 releases the photo paper roll 5, and the photo paper roll 5 can automatically slide down along the conical cylinder 21 in the opposite direction, without human intervention, thereby achieving convenient unloading.

[0037] Please continue reading Figure 1One end of the cross frame 3 is rotatably connected to the guard plate assembly 4 through a rotating shaft 31. The cross frame 3 is equipped with a driving assembly 32, which can push the guard plate assembly 4 to flip over to move away from the carrying rod assembly 2 and scratch the plastic film debris on the guard plate assembly 4. The outer sleeve of the rotating shaft 31 is provided with a torsion spring for driving the guard plate assembly 4 to return to the center. The two ends of the torsion spring are respectively connected and fixed to the guard plate assembly 4 and the cross frame 3. When the driving assembly 32 pushes the guard plate assembly 4 away, it can also scratch and drop the plastic film debris on the side of the guard plate assembly 4 close to the carrying rod assembly 2, which is convenient for loading the photo paper roll 5 and can also conveniently clean the plastic film debris remaining on the guard plate assembly 4, avoiding the trouble of manual cleaning of the plate body 41.

[0038] See also Figure 3 The guard plate assembly 4 includes: a plate body 41 and a stopper 42. A rectangular opening 411 is provided at one end of the plate body 41 for the cross frame 3 to pass through. One end of the plate body 41 is rotatably connected to the cross frame 3 at the rectangular opening 411 through the rotating shaft 31. The stopper 42 is provided on the other end of the plate body 41 and is used to press against the photo paper roll 5 when the plate body 41 approaches the carrying rod assembly 2. The flippable plate body 41 is used to press against one side of the photo paper roll 5 when the plate body 41 rotates close to the carrying rod assembly 2, thereby providing partial support when the photo paper roll 5 is fixed on the carrying rod assembly 2.

[0039] See also Figure 4 The stopper 42 includes: a connecting frame 421, a cavity 4211 is provided inside the connecting frame 421, a plurality of vertically arranged and mutually spaced columnar grooves 412 are opened at one end of the plate body 41, a rotating roller 422 is rotatably connected to the inner wall of the bottom end of the columnar groove 412, the upper end of the rotating roller 422 extends into the cavity 4211 and is rotatably connected to the connecting frame 421, an annular ratchet groove 4221 is provided on the upper end of the rotating roller 422 along its own circumference, and the inner wall of the cavity 4211 is provided with The pawl 4212 is adapted to the annular ratchet groove 4221 and is rotatably assembled on the inner wall of the cavity 4211. By utilizing the unidirectionally rotatable rotating roller 422, the friction generated by the rotating roller 422 and the photo paper roll 5 when the photo paper roll 5 is loaded is reduced. When the photo paper roll 5 is subsequently fixed, the rotating roller 422 cannot rotate in the opposite direction due to the engagement between the pawl 4212 and the annular ratchet groove 4221, thereby providing a certain support force on the side of the photo paper roll 5.

[0040] See also Figure 5The driving assembly 32 includes an electric push rod 321, which is fixedly assembled on the horizontal frame 3. The driving shaft of the electric push rod 321 is fixedly connected to a scraper 322. By arranging the scraper 322 on the driving shaft of the electric push rod 321, the scraper 322 can push the guard plate assembly 4 to flip over, and at the same time, it can scrape off the plastic film debris adhering to the plate body 41.

[0041] See also Figure 6 The cross frame 3 is fixedly equipped with an arc segment 33 at one end, and the cross section of the arc segment 33 is semicircular. The arc segment 33 is provided with spaced rubber strips 331. A connecting strip 413 is equipped on the side of one end of the plate body 41 away from the stopper 42. One end of the connecting strip 413 extends to contact the surface of the arc segment 33. One end of the plate body 41 is set to an arc segment 33 with a semicircular cross-section, so that when the plate body 41 is pushed and deflected by the driving assembly 32, the rubber strip 331 is squeezed and rebounded by the connecting strip 413, and vibration is generated. The vibration is transmitted to the carrying rod assembly 2, so that the photo paper roll 5 can quickly detach from the carrying rod assembly 2.

[0042] See also Figure 7 A plurality of annular rubber rings 231 are arranged at intervals on the outside of the inflatable shaft 23, and a plurality of annular grooves 211 are opened at intervals on the inner wall of the opening at one end of the conical cylinder 21. When the inflatable shaft 23 retracts into the interior of the conical cylinder 21, the rubber rings 231 can be continuously squeezed and rebounded through the annular grooves 211, thereby further vibrating the carrying rod assembly 2 and increasing the speed of sliding and unloading the photo paper roll 5.

[0043] See also Figure 8 and Figure 9 The inside of the conical tube 21 is fixedly equipped with a plurality of triangular reinforcement rings 212 along its own length direction. The telescopic rod 22 passes through the triangular reinforcement ring 212. The outside of the telescopic rod 22 is sleeved with a plurality of elastic rings 221. The diameter of the elastic ring 221 is larger than the diameter of the inscribed circle of the triangular reinforcement ring 212. When the telescopic rod 22 drives the inflatable shaft 23 to retract, the elastic ring 221 is continuously squeezed by the triangular reinforcement ring 212 and elastically deformed when following the movement of the telescopic rod 22, further intensifying the vibration effect of the entire carrying rod assembly 2, making it convenient to unload the photo paper roll 5.

[0044] See also Figure 10The stand 1 includes: a connecting disk 11 and a frame body 12. The upper end of the connecting disk 11 is connected and fixed to the driving device. The lower end of the connecting disk 11 is provided with a connecting column 111. The upper end of the frame body 12 is provided with a connecting piece 121. A cylindrical cavity is provided inside the connecting piece 121. The connecting piece 121 is hinged to the connecting piece 121 at the cylindrical cavity. A fastening bolt 122 is screwed on the connecting piece 121. When the carrying rod assembly 2 undergoes slight deformation due to long-term use, the angle between the frame body 12 and the connecting disk 11 is adjusted to make it easier for the carrying rod assembly 2 to insert the photo paper roll 5 and grab it for transportation.

[0045] When the paper roll 5 is to be taken out of the container 20, the container 20 is moved to the location of the container 20. When the paper roll 5 is to be taken out of the container 20, the container 20 is moved to the location of the container 20. When the paper roll 5 is to be taken out of the container 20, the container 20 is moved to the location of the container 20. When the paper roll 5 is to be taken out of the container 20, the container 20 is moved to the location of the container 20. When transported to the unloading location, by loosening the inflatable shaft 23, the reel 51 of the photo paper roll 5 loses the interference effect with the inflatable shaft 23, and the reel 51 automatically slides down along the outside of the conical cylinder 21, thereby achieving rapid unloading of the photo paper roll 5.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
