Description

Technical Field

[0001] The present invention relates to the field of mechanical equipment manufacturing, and in particular to a photo paper dispensing device. Background Art

[0002] Currently, photo paper is shipped from the original manufacturer in bulk packages of tens of thousands or even hundreds of thousands of sheets. Dealers or distributors who receive these bulk packages are required to separate these packages into bags of ten or dozens of sheets for sale or to supply to downstream vendors. However, the existing method of sorting photo paper relies primarily on manual distribution, which is inefficient and prone to leaving stains (fingerprints) or scratches on the surface of the photo paper. Manual distribution is also costly and prone to miscounting. Furthermore, it is difficult to organize the paper after distribution, requiring it to be flipped and integrated before packaging. This process can easily damage the surface and edges of the photo paper, and can easily cause paper jams during the printing process.

[0003] In summary, the existing photo paper dispensing device needs to be further improved and enhanced. Summary of the Invention

[0016] Furthermore, the connecting sleeve is provided with an arc-shaped groove for adjusting the angle of the recessed portion, and the curvature of the arc-shaped groove is the same as the curvature of the outer circumference of the connecting sleeve.

[0017] Furthermore, the second driving mechanism includes at least two cylinders, and is respectively used to drive the receiving plate and the blocking plate to move toward the discharge port opened on the frame.

[0018] Furthermore, it also includes a guide plate with an inclined surface, which is detachably installed at the edge of the discharge port to guide the photo paper into the receiving tray or the blocking tray and to regularize photo papers of different sizes.

[0019] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention provides a photo paper dispensing device with a simple structure, simple manufacture, easy implementation and low cost, which solves the problems of low efficiency and easy damage to the surface of photo paper in existing manual dispensing. The present invention adopts a photo paper dispensing device composed of a storage mechanism, a rotating pickup mechanism and a stacking mechanism to realize automatic dispensing of photo paper, and takes the back of the photo paper by a vacuum adsorption component without damaging the photo paper. The stacking mechanism accurately receives the photo paper. The present invention adopts a double receiving structure of a receiving tray and a blocking tray to greatly improve the dispensing efficiency. After the receiving tray receives a set number of photo papers, when it runs to the packaging station for packaging, the blocking tray can first receive the photo paper to avoid mixing with new photo papers or stopping to wait for the photo papers to be displaced before the next receiving, which greatly improves the efficiency.

[0021] (2) The present invention adopts a storage mechanism formed by a combination of a material rack, a material stopper rod and a supporting member. This method maximizes the freedom of photo paper from being restricted, making it easier to remove photo paper when taking it out. The material rack supports the material rack and uses its own weight to press against the material stopper rod and the supporting member. The material stopper rod and the supporting member restrict two points and a line of the photo paper, leaving a larger paper removal space. That is, under the premise of being able to store material, the photo paper can be easily removed, and the contact points are minimized to avoid damage to the photo paper.

[0022] (3) The present invention also uses a first adjustment structure to achieve displacement of the blocking rod at the height of the material rack, so that photo papers of different sizes can be placed, thereby improving the scope of application of the photo paper dispensing mechanism; similarly, a second adjustment structure is also provided on the abutting member to achieve adjustment in different length directions of the photo paper, which not only improves the scope of application but also facilitates adjustment when taking out the photo paper, thereby preventing the situation where too much photo paper is pressed against the material rack, making it difficult to extract the photo paper. The second adjustment structure adjusts the position of the two abutting members to facilitate the removal of the photo paper;

[0023] (4) The first driving component of the present invention includes a motor, a driving gear and a plurality of linkage gears, and each of the linkage gears is connected to a corresponding connecting shaft and meshes with the driving gear respectively; the direction of rotation of the linkage gear is opposite to that of the driving gear, and the number of teeth of the driving gear is the number of teeth of the linkage gear multiplied by the number of connecting shafts; the connecting shaft is set to be rotatable and reverses when the mounting frame rotates forward. After the photo paper is adsorbed, there is a force in the opposite direction of the mounting frame to remove the photo paper from the material holder without causing interference. Moreover, a vacuum adsorption component with photo paper is already loaded on the mounting frame. When the connecting rod is vertically downward, the photo paper on the vacuum adsorption component also accurately corresponds to the receiving tray or the blocking tray. This structural design is ingenious. While solving the problem of not being able to remove the photo paper smoothly, it can also ensure that the movable vacuum adsorption component can accurately drive the photo paper to be positioned on the receiving tray.

[0024] (5) The present invention also includes several sets of transmission belts and auxiliary gears for driving the driving gear and the linkage gear, which not only realizes the synchronous movement of at least three linkage gears, but also reduces the driving force of the motor to simultaneously drive the three connecting shafts (loads) to move synchronously, and plays a good protective role;

[0025] (6) The present invention also has a vacuum breaking component, which realizes mechanical vacuum breaking through the cooperation of several vacuum breaking valves and the mounting sleeve. Compared with the vacuum breaking method of the sensor, the vacuum breaking component of the present invention has a faster response speed and is more accurate, avoiding the shutdown or alarm caused by untimely sensing; in addition, it is more flexible in the adjustment process;

[0026] (7) The present invention is also provided with an arc groove for adjusting the angle, which makes it more convenient and more accurate to adjust the vacuum breaking position;

[0027] (8) The present invention uses a cylinder as a driving member to drive the receiving plate and the blocking plate to move toward the discharge port in a switching manner, which has a simple structure and good response speed;

[0028] (9) The present invention also adds a guide plate with an inclined surface at the discharge port to simultaneously implement the introduction of photo paper, which can be adjusted to allow photo paper of different sizes to enter in an orderly manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] For specific implementation, see Figure 1-6 The photo paper dispensing device described in the present invention mainly includes the following components: a frame 1, a storage mechanism 2, a rotary pickup mechanism 3, a stacking mechanism 4, a material rack 21, a material blocking rod 22, a supporting member 23, a first rotary lock member 51, a bar hole 52, two slides 61, a slide rail 62, a second rotary lock member 63, a mounting frame 31, a first driving assembly 32, a motor 321, a driving gear 322, a plurality of linkage gears 323, a transmission toothed belt 324, a plurality of auxiliary gears 325, at least three groups of vacuum adsorption assemblies 33, a second driving mechanism 41, a material receiving tray 42, a material blocking tray 43, a guide plate 44, a mounting sleeve 81, a plurality of vacuum breaking valves 82, a recessed portion 811 and a counter 9.

[0057] During actual assembly:

[0058] (1) Assembling the material storage mechanism 2: first, assemble a material rack 21 through four connecting plates 211, and open strip holes 52 on the connecting plates on the left and right sides of the material rack 21 along the height direction. After the material blocking rod 22 passes through the strip holes 52, the two ends of the material blocking rod 22 are exposed outside the two connecting plates respectively, and are threadedly engaged through the first rotary lock member 51. The first rotary lock member 51 is tightly fitted on the outer periphery of the two connecting plates to limit the position of the material blocking rod 22 at the height of the material rack 21;

[0059] (2) A slide rail 62 is provided near the lower connecting plate 211. The slide rail 62 is provided parallel to the stop rod 22 and is provided for mounting the two slide seats 61. Abutment members 23 are detachably mounted on the two slide seats 61. It should be noted that a guide wheel 230 is mounted on the abutment member 23, and the abutment member 23 can be displaced relative to the slide seat 61 by threaded engagement, so that the abutment member 23 is displaced along the axial direction of the vertical stop rod 22.

[0060] (3) A plurality of fixing rods 24 are provided in a direction perpendicular to the plane formed by the blocking rod 22 and the abutting member 23 to form a hopper 25 for supporting the photo paper;

[0061] (4) The entire storage mechanism 2 is pushed to move by a pushing structure, which includes a mounting plate 26, a guide post 27, a screw 28 and a rotating wheel 29. The mounting plate is fixed to the frame 1 and is provided for mounting two guide posts 27. The material rack 21 of the discharging structure passes through the guide posts 27. One end of the screw 28 is fixed to the rotating wheel 29, and the other end is threadedly passed through the mounting plate 26 and connected to the material rack 21. The rotating wheel 29 is rotated to drive the screw 28 to push or pull the material rack 21 to move along the axis of the guide post 27. This design is used for subsequent adjustment of the alignment of the photo paper and the vacuum adsorption component 33, which is convenient for adjustment.

[0062] (5) Assemble the stacking mechanism 4, which is arranged at the lower part of the frame 1, and is used to receive and stack the set number of photo papers and then put them down to the conveyor chain; during assembly, the cylinder body of each cylinder 411 is fixed to the frame 1, and the upper receiving plate 42 and the blocking plate 43 are fixed to the piston rod of each cylinder 411. It should be noted that the present invention symmetrically arranges two blocking plates 43 and the receiving plate 42, which can shorten the movement stroke, time and corresponding lifting speed of the blocking plate 43 and the receiving plate 42, and the blocking plate 43 is located above the receiving plate 42, and is used to receive the newly fallen photo papers when the receiving plate 42 is full and the set number of photo papers are transferred to the next process. The blocking plate 43 pre-receives the newly fallen photo papers, and when the photo papers on the receiving plate 42 are emptied, the blocking plate 43 opens and drops the received photo papers onto the receiving plate 42;

[0063] (6) A guide plate 44 having an inclined surface is fixed by screw threads at the edge of the discharge port B. The guide plate 44 not only guides the photo paper to enter the retaining plate 43 or the receiving plate 42 smoothly and regularly through its inclined surface, but also can adjust the position of the guide plate 44 so that photo paper of different sizes can be stacked smoothly and regularly;

[0064] (7) A counter 9 is installed on the frame 1 near the discharge port B. The counter can be realized by a photosensor, a distance sensor, etc.; as long as it can sense the photo paper, and the counter is incremented by 1 after sensing;

[0065] (8) Assemble the rotating pickup mechanism 3. First, the mounting frame 31 includes two discs 311 and a main shaft 312. The two discs 311 and the main shaft 312 are arranged coaxially, while the connecting shaft 7 is arranged eccentrically relative to the main shaft 312. Each connecting shaft 7 is first sleeved with a vacuum adsorption component 33 and then the two ends are connected to the bearings on the disc 311, so that the connecting shaft 7 can rotate relative to the disc 311. Secondly, the two ends of the main shaft 312 pass through the disc 311 respectively, and one end is sleeved with a driving gear 322 to prevent rotation, and the end of the main shaft 312 is connected to the motor 321. Then, a linkage gear 323, a transmission toothed belt 324, and various auxiliary gears 325 are installed on the disk 311 at this end. It should be noted that the linkage gears 323 are respectively mounted on the ends of each connecting shaft 7 in a rotationally fixed manner; four auxiliary gears 325 are installed near each connecting shaft 7, and the transmission toothed belt 324 is wrapped around the outer circumference of the auxiliary gears 325 and meshes with the driving gear 322 and the linkage gear 323. When the main shaft 312 rotates, the driving gear 322 rotates with the disk 311, driving the linkage gears 323 to rotate in the opposite direction.

[0066] (9) A mounting sleeve 81 is sleeved on the other end of the main shaft 312, and the mounting sleeve 81 is fixed to the frame 1; it should be noted that a recessed portion 811 is formed on the outer wall of the mounting sleeve 81, and the recessed portion 811 smoothly transitions with the outer wall; the installation of the mounting sleeve 81 is adjustable, that is, an arcuate groove 812 is provided on the mounting sleeve 81, and the mounting sleeve 81 is mounted on the frame 1 by screws to achieve a rotation angle of the recessed portion 811 on the mounting sleeve 81;

[0067] (10) A vacuum breaking valve 82 is provided on the disc 311 at the other end of the main shaft 312. The ends of each vacuum breaking valve 82 respectively abut against the outer periphery of the mounting sleeve 81. Each vacuum breaking valve 82 is used to connect with the vacuum adsorption assembly 33. After the vacuum adsorption assembly 33 adsorbs the photo paper, it moves with the disc 311 to the corresponding discharge port B. At this time, the vacuum breaking valve 82 rotates with the disc 311 to the position of the recessed portion 811 of the mounting sleeve 81. The vacuum breaking valve 82 is mechanically triggered, causing the vacuum adsorption assembly 33 to break the vacuum, and the photo paper adsorbed thereon falls to the discharge port B.

[0068] When using:

[0069] (1) A batch of photo papers is placed on the fixed rod 24. The photo papers will lean against the blocking rod 22 and the abutment member 23 by their own weight, and the position between the blocking rod 22 and the abutment member 23 forms a paper taking area A. It should be noted that the blocking rod 22 and the abutment member 23 are adjustable in position to accommodate photo papers of different sizes. In addition, a guide wheel 230 is provided on the abutment member 23 to facilitate the removal of photo papers. In addition, the present invention also provides an adjustable overall height push-up structure for corresponding adjustment of the storage mechanism 2 and the vacuum adsorption component 33.

[0070] (2) The motor 321 works, driving the main shaft 312 to rotate. At this time, the driving gear 322, the disc 311, the connecting shaft 7 on the disc 311, the vacuum breaking valve 82 and other components that are fixed with the main shaft 312 rotate synchronously; as they rotate, the vacuum adsorption component 33 on the connecting shaft 7 corresponds to the photo paper and adsorbs the photo paper; during the rotation process, since the connecting shaft 7 is rotatable and has a rotation direction opposite to that of the main shaft 312, that is, the driving gear 322 is used as the power source, the transmission belt 324 cooperates with the auxiliary gear to drive the linkage gear 323 on the connecting shaft 7 to rotate in the opposite direction, and the connecting shaft 7 rotates in the opposite direction when the disc 311 rotates forward, thereby smoothly peeling the photo paper off from the material blocking rod 22 and the abutment member 23 without damaging the photo paper; the present invention takes three connecting shafts 7 as an example, so the number of teeth of the linkage gear 323 is one-third of that of the driving gear 322, that is, the driving gear 322 rotates one circle and the linkage gear 323 rotates three circles;

[0071] (3) When the vacuum adsorption component 33 carries the photo paper and rotates along with the main shaft 312 to the position of the discharge port B, it is sensed by the counter 9 and the number of photo papers is increased by 1. At this time, the vacuum breaking valve 82 corresponding to the connecting shaft 7 also falls into the recessed portion 811, so the corresponding vacuum adsorption component 33 breaks the vacuum, so that the photo paper falls on the blocking plate 43 or the receiving plate 42. It should be noted that the present invention adopts this mechanical vacuum breaking method, firstly, to improve the stability of the vacuum breaking, and secondly, in the process of rapid operation of adsorption and paper taking, breaking the vacuum and placing the paper, the existing electric control vacuum breaking method cannot respond quickly, and is prone to problems of timely response, and the angle is difficult to adjust. In order to make the photo paper fall into the discharge port B when the vacuum adsorption structure breaks the vacuum, it is necessary to break the vacuum a little in advance. At this time, the time and angle of the vacuum breaking need to be adjusted. The present invention can easily achieve adjustment by angle setting, and the response speed is fast.

[0072] (4) The receiving tray 42 receives the falling photo papers and limits the photo papers to the corresponding size in the receiving tray 42 through the guide plate 44, so that the photo papers are easy to stack and are regular. When the number of photo papers set by the human is reached, the cylinder 411 of the receiving tray is activated to drop the photo papers and transfer them to the packaging machine through the transmission chain for packaging. It should be noted that after the receiving tray 42 receives the corresponding number of photo papers, it needs to fall to the next process, and the newly fallen photo papers cannot be received during this period. , it is easy to have procedural or quality problems, so when the receiving tray 42 is doing its corresponding process work, that is, after obtaining the corresponding number of photo papers, the cylinder 411 of the blocking tray 43 is actuated to push the blocking tray 43 out, and the blocking tray 43 first receives the fallen photo papers, and after the receiving tray 42 is reset, the blocking tray 43 is opened, and the stacked photo papers fall into the receiving tray 42 to receive them, until the number of sheets set by humans is reached, the blocking tray 43 is actuated, and this cycle is repeated.

[0073] The present invention provides a photo paper dispensing device with a simple structure, simple production, easy implementation and low cost, which solves the problems of low efficiency and easy damage to the surface of photo paper in existing manual dispensing. The present invention adopts a photo paper dispensing device composed of a storage mechanism, a rotating pickup mechanism and a stacking mechanism to realize automatic dispensing of photo paper, and takes the back of the photo paper by a vacuum adsorption component without damaging the photo paper. The stacking mechanism accurately receives the photo paper. The present invention adopts a double receiving structure of a receiving tray and a blocking tray to greatly improve the dispensing efficiency. After the receiving tray receives a set number of photo papers, when it runs to the packaging station for packaging, the blocking tray can first receive the photo papers to avoid mixing with new photo papers or stopping the machine to wait for the photo papers of the completed number to be displaced before proceeding. The next takeover can be carried out, which greatly improves efficiency; the present invention adopts a storage mechanism formed by a material rack, a material stop rod and a supporting member. This method maximizes the liberation of restrictions on photo paper, making it easier to take out photo paper when taking it out, supported by the material rack, and with its own weight against the material stop rod and the supporting member, and the material stop rod and the supporting member limit two points and a line of the photo paper, retaining a larger paper taking space, that is, while maintaining the ability to store material, the photo paper can be easily taken out, with as few contact points as possible to avoid damage to the photo paper; the present invention also uses a first adjustment structure on the material stop rod to achieve the displacement of the material stop rod on the material rack height, so that photo papers of different sizes can be placed, thereby improving the applicability of the photo paper dispensing mechanism; similarly, on the supporting member A second adjustment structure is also provided to achieve adjustment of the photo paper in different length directions, which not only improves the scope of application, but also can be adjusted for convenience when taking out the photo paper, to prevent the situation where too much photo paper is pressed against the material rack and it is difficult to pull out the photo paper. The position of the two abutting members is adjusted by the second adjustment structure to facilitate the removal of the photo paper; the first driving component of the present invention includes a motor, a driving gear and a plurality of linkage gears, and each of the linkage gears is respectively connected to the corresponding connecting shaft and meshes with the driving gear respectively; the direction of rotation of the linkage gear is opposite to that of the driving gear, and the number of teeth of the driving gear is the number of teeth of the linkage gear multiplied by the number of connecting shafts; the connecting shaft is set to be rotatable, and when the mounting frame rotates forward After the photo paper is sucked in reverse, a force in the opposite direction of the mounting frame is generated to remove the photo paper from the material holder without causing interference. Moreover, the mounting frame already has a vacuum suction component loaded with photo paper. When the connecting rod is vertically downward, the photo paper on the vacuum suction component is also accurately aligned with the receiving tray or the retaining tray. This ingenious structural design solves the problem of not being able to remove the photo paper smoothly while ensuring that the movable vacuum suction component can accurately drive the photo paper to align with the receiving tray. The present invention also includes several sets of transmission toothed belts and auxiliary gears for driving the driving gear and the linkage gear. This not only realizes the synchronous movement of at least three linkage gears, but also reduces the driving force of the motor to simultaneously drive the three connecting shafts (loads) to move synchronously, thereby playing a good protective role.The present invention also includes a vacuum breaker assembly, which achieves mechanical vacuum breaker by cooperating with several vacuum breaker valves and a mounting sleeve. Compared with the sensor vacuum breaker method, the vacuum breaker assembly of the present invention has a faster and more accurate response speed, avoiding shutdowns or alarms caused by untimely sensing. In addition, it is more flexible during the adjustment process. The present invention also includes an arc groove for adjusting the angle, which is more convenient and more accurate when adjusting the vacuum breaker position. The present invention uses a cylinder as a driving member to drive the receiving tray and the material blocking tray to move toward the discharge port in a switching manner, which has a simple structure and good response speed. The present invention also adds a guide plate with an inclined surface at the discharge port to simultaneously guide photo paper, which can be adjusted to ensure that photo paper of different sizes enters in a regular manner.
