Description

Technical Field

[0001] The present invention relates to the technical field of self-service equipment, and in particular to a self-service film-taking device for convenient film replacement and a method for using the device. Background Art

[0002] Self-service film retrieval machines are currently widely used in the imaging industry. They are mainly used to provide fast and convenient self-service retrieval services for photos, images, movies and other materials. Common application scenarios of self-service film retrieval machines include hospitals, imaging service centers, imaging studios, photo printing shops, etc.

[0003] The existing medical CT film self-service machine has a built-in film storage bin for placing films. A clamping structure is provided in the film storage bin for clamping the films and arranging and aligning the films. However, the existing clamping structure has poor aligning effect when replacing the films, and the films will be offset to a certain extent, resulting in jams. Therefore, the publication number CN209554401U discloses a stacked paper pile alignment device, which includes a base plate, a corner alignment reference plate, a side alignment reference plate and a paper pile combination pallet; the base plate is provided with a pallet sliding groove, and the pallet sliding groove is rectangular and two adjacent sides thereof coincide with two adjacent side walls of the base plate, the corner alignment reference plate and the side alignment reference plate are both located on the upper end surface of the base plate and are both located at the edge of the pallet sliding groove, the paper pile combination pallet is located in the pallet sliding groove, and the paper pile combination pallet includes a main pallet and a secondary pallet.

[0004] The above-mentioned alignment device can level the stacks of paper as a whole and facilitate the removal of the leveled paper stacks through the coordinated use of the base plate, the edge and corner alignment reference plate, the side alignment reference plate and the paper stack combination support plate. The leveling operation is simple and easy, reducing manual labor intensity. At the same time, it can greatly improve the flatness of the paper stack, which is conducive to ensuring printing accuracy and avoiding paper jams in the offset printing machine.

[0005] However, when the above-mentioned alignment device is used, the film needs to be placed accurately into the sliding groove of the support plate, which has high requirements on the placement position of the film and is inconvenient to replace the film. In addition, the film bin in the existing self-service film dispenser is located inside the self-service film dispenser. Due to the small internal space of the film bin, it is difficult to take out the film from the film bin if necessary.

[0020] The present invention also provides a film replacement method for a self-service film retrieval device, comprising the self-service film retrieval device for convenient film replacement, and further comprising the following steps:

[0021] S1. First, open the cover, pull the tray out of the film compartment, then open the outer cover, and then place the film on the placement tray, placing it between the side extrusion assembly, the front extrusion assembly, and the rear baffle;

[0022] S2. After placement is completed, the outer cover is closed so that the bottom of the outer cover is in contact with the bottom of the tray. As the outer cover is closed, the side squeezing components and the front squeezing components are triggered to operate. The side squeezing components are used to squeeze and align the two sides of the film, and the front squeezing components cooperate with the rear baffle to align the front and back of the film.

[0023] S3. After the films are aligned by the side extrusion components and the front extrusion components, they are aligned up and down. After the outer cover is closed, the upper extrusion component presses and smoothes the upper part of the films to prevent them from arching. After the films are aligned, the upper extrusion component is used to transport the films.

[0024] Compared with the existing technology, the advantages of the present invention are:

[0025] 1. When replacing films, the self-service film-taking device can align the films by providing a side squeezing assembly, a front squeezing assembly, and a rear baffle. A first pressing wedge and a second pressing wedge that cooperate with the side squeezing assembly and the front squeezing assembly are provided on the outer cover. The alignment operation can be automatically achieved when the outer cover is closed. The requirements for the position of the film placement are low, and no driving device is required, so the stability is higher.

[0026] 2. When replacing films, this self-service film retrieval device can pull out the placement tray from the film retrieval cabinet by setting up a slide rail yi8ji tray, and then replace and place the film. The operation space is large and the replacement is more convenient. In addition, pulling out the placement tray to replace the film can more accurately control the position of the film placement, reduce the probability of film deflection, and improve the efficiency of film replacement.

[0027] 3. When replacing the film, the self-service film retrieval device sets an upper squeezing component to press the top of the film to prevent the film from arching, which facilitates the film transportation. Combined with the use of a lifting top and a rotatable rubber wheel, it can ensure that the position of each film when it is transported from the placement tray is fixed, thereby reducing the probability of the film getting stuck during transportation.

[0028] 4. When replacing the film, the self-service film retrieval device fixes the position of the push wheel by setting a locking mechanism, and uses a pressure sensor to control the pressure between the push wheel and the film, which can effectively avoid the probability of the film being squeezed and deformed, ensure the normal shape of the film, and avoid the situation where the push wheel is worn out due to long-term use and the pressure is not tight, making the position of the film more fixed and reducing the probability of film deviation.

[0029] To sum up, the present invention pulls out the placement tray from the film retrieval cabinet when replacing the film, making the film replacement more convenient and the operation more convenient. In addition, the side extrusion assembly and the front extrusion assembly are operated by the rotation and closure of the outer cover to realize automatic film alignment. There is no need for a driving source to drive the alignment, the stability is higher, the film output position is constant, the probability of film jams is reduced, and the film transportation is more stable.

DETAILED DESCRIPTION

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] Example 1: Reference Figure 1-Figure 5 、 Figures 8-18 、 Figure 20 A self-service film retrieval device for convenient film replacement includes a film retrieval cabinet 1 and a control panel 3 installed on the film retrieval cabinet 1, and also includes a film compartment 4 arranged inside the film retrieval cabinet 1, and a cover plate 2 that is rotatably mounted on the film retrieval cabinet 1 and matches the film compartment 4;

[0054] A tray 5 is slidably installed in the film compartment 4 through a slide rail 6, and a placement plate 7 is installed on the tray 5 through a lifting assembly. Film 9 is placed on the placement plate 7, and an outer cover 8 that matches the film 9 is rotatably installed on the tray 5 (here, film 9 is a general term for a large number of films stacked together); the cover 2 can only be opened to ninety degrees, and two rows of support wheels are rotatably installed inside the cover 2 to support the slide rail 6 to prevent the slide rail 6 from protruding too much from the film retrieval cabinet 1 and causing the slide rail 6 to bend. The slide rail 6 is a common sliding rail in the existing market, and its specific operation and specific structure are not explained here.

[0055] The lifting assembly includes a first motor 26 and a lifting top 27 fixedly mounted on the tray 5 . The driving end of the first motor 26 and the lifting top 27 are connected via a telescopic universal shaft 28 .

[0056] The rotation of the driving end of the first motor 26 will drive the lifting top 27 to rise and fall through the telescopic universal shaft 28, thereby realizing the lifting and lowering of the placement tray 7. As the film 9 is used, the placement tray 7 will continue to move upward (the upward direction here is the side away from the tray 5), and the distance of each movement is the thickness of a single film 9.

[0057] The lifting top 27 is a common lifting device and will not be described in detail here;

[0058] The purpose of using the telescopic universal shaft 28 is that when the lifting top 27 is raised or lowered, the connection point with the driving shaft of the first motor 26 will change, so the telescopic universal shaft 28 is used to connect the lifting top 27 and the first motor 26 to ensure that the driving end of the first motor 26 always drives the lifting top 27 to operate.

[0059] The placement tray 7 is provided with a side extrusion assembly 10 and a front extrusion assembly 11 which match the film 9 .

[0060] The side extrusion assembly includes a plurality of fixed blocks 14 slidably mounted on the placement tray 7. The plurality of fixed blocks 14 are divided into two groups, and the two groups are located on both sides of the placement tray 7. The adjacent fixed blocks 14 are fixedly connected by a connecting rod. Two first elastic telescopic rods 17 are fixedly mounted on each fixed block 14. The telescopic ends of the two matching first elastic telescopic rods 17 are jointly fixedly mounted with a wheel frame, and a pushing wheel 15 that cooperates with the film 9 is rotatably mounted on the wheel frame. Two pushing mechanisms that cooperate with the corresponding fixed blocks 14 are installed on the placement tray 7.

[0061] Multiple fixed blocks 14 on the same side will move simultaneously toward the side close to the film 9 under the action of the pushing mechanism and the connecting rod. The movement of the fixed block 14 drives the first elastic telescopic rod 17 to move. The first elastic telescopic rod 17 will drive the wheel frame and the pushing wheel 15 rotatably mounted on the wheel frame to move, so that the pushing wheel 15 is against the side of the film 9. When the pushing wheel 15 is against the film 9, the fixed block 14 continues to move, compressing the first elastic telescopic rod 17, increasing the pressing force between the pushing wheel 15 and the film 9, and making the films 9 aligned.

[0062] The pushing mechanism includes a push rod 20 fixedly mounted on the fixed block 14, and a sleeve 19 is mounted on the push rod 20 through an adjustment structure;

[0063] The adjustment structure includes a screw 21 fixedly mounted on the push rod 20, a slide fixedly mounted on the screw 21, the slide being slidably connected to the sleeve 19, and a nut 22 rotatably mounted on the sleeve 19 and threadably connected to the screw 21;

[0064] Turn the nut 22 to make the screw 21 slide in the sleeve 19, thereby changing the distance between the sleeve 19 and the push rod 20, thereby changing the initial position of the fixed block 14. Since the initial position of the sleeve 19 remains unchanged, after the initial position of the fixed block 14 is changed, the distance between the push wheel 15 and the film 9 changes. At this time, the sleeve 19 moves the same distance, and the position of the fixed block 14 is different, so that films 9 of different widths can be aligned.

[0065] The sleeve 19 is fixedly mounted with a frame 18, on which two side pressing wheels 13 are rotatably mounted. The outer cover 8 is fixedly mounted with two first pressing wedges 34 that cooperate with the two corresponding sets of side pressing wheels 13. The outer cover 8 is mounted with a pressure control structure that cooperates with a plurality of pushing wheels 15.

[0066] When the outer cover 8 is closed, the first pressing wedge 34 on the outer cover 8 will abut against the side pressing wheel 13. Since the first pressing wedge 34 is triangular, as the first pressing wedge 34 moves, it will generate a pressing force on the side pressing wheel 13. Under the action of this pressing force, the push rod 20 moves on the placement plate 7, thereby driving the fixed block 14 to move.

[0067] Since the low pressure on both sides required to align the films 9 is relatively large, the pressure strength between the first pressure wedge 34 and the side pressure wheel 13 is required to be relatively high. In order to ensure that the pressure strength meets the standard and no external force is applied by hand, the weight of the outer cover 8 itself needs to meet the pressure strength between the first pressure wedge 34 and the side pressure wheel 13.

[0068] The pressure control structure includes a third motor fixedly mounted on the outside of the outer cover 8, a pressure sensor fixedly mounted on the driving end of the third motor, a toothed disc 23 fixedly mounted on the pressure sensor, two racks 24 meshing with the toothed disc 23 are slidably mounted on the outer cover 8, and a fixing plate is fixedly mounted on the two racks 24. The fixing plate passes through the outer cover 8 and extends into the interior of the outer cover 8. A groove body that cooperates with the fixing plate is opened on the outer cover 8. A magnetic plate 32 is fixedly mounted on each of the two fixing plates, and a telescopic magnetic rod 16 that cooperates with the corresponding magnetic plate 32 is rotatably mounted on each push wheel 15.

[0069] Under the action of the lifting assembly, the placement tray 7 will continue to move up. Since the first pressing wedge 34 is triangular, when the pushing wheel 15 contacts the film 9, the side pressing wheel 13 moves to the middle position of the first pressing wedge 34 (the purpose of this design is: since each time the film 9 is transported out of the placement tray 7, the overall thickness of the film 9 will change. If the pushing wheels 15 on both sides remain stationary at this time, the adhesion between the films 9 will cause the film 9 at the top and the film 9 below it to be taken out at the same time, thereby causing a jam. The first pressing wedge 34 is used, and after the clamping is aligned, the side pressing wheel 13 is located in the middle of the first pressing wedge 34). As the placement tray 7 moves upward, the side pressure wheel 13 will continue to drive the pushing wheel 15 to move, increasing the pressure on the film 9 and reducing the probability of the lower film 9 being brought out. Generally, the effect is obvious when the last few films 9 are being put out, because the last few films 9 are light and easier to be brought out). As the pressure between the pushing wheel 15 and the film 9 increases, when the film 9 is thicker, the pressure increase each time is not large, so the effect is not great. Once there are only a few films 9 left, the pressure at this time is very likely to cause the side of the film 9 to deform. Therefore, it is necessary to use a pressure control structure to regulate the pressure between the pushing wheel 15 and the film 9. The specific regulation method is as follows:

[0070] The pressure sensor on the driving end of the third motor will sense the torque from the toothed disc 23, which is the pressing force of the rack 24 on the toothed disc 23. When the rack 24 is fixed, suction will be generated between the magnetic plate 32 and the telescopic magnetic rod 16. The suction will be transmitted to the pressure sensor through the fixed plate, the rack 24 and the toothed disc 23. Then the pressure sensor controls the operation of the third motor to change the suction between the magnetic plate 32 and the telescopic magnetic rod 16. The change in suction will change the pressure between the pushing wheel 15 and the film 9, thereby maintaining the pressure balance between the pushing wheel 15 and the film 9, which can effectively prevent the probability of the film 9 below being brought out, and can also reduce the probability of the film 9 being squeezed and deformed.

[0071] The front end extrusion assembly 11 includes a sliding frame 43 slidably mounted on the placement plate 7, a plurality of third elastic telescopic rods 42 are fixedly mounted on the sliding frame 43, and a push plate 41 that cooperates with the film 9 is fixedly mounted at the telescopic ends of the plurality of third elastic telescopic rods 42. Two front pressure wheels 40 are rotatably mounted on the sliding frame 43, and a second pressure wedge that cooperates with the two front pressure wheels 40 is fixedly mounted on the outer cover 8.

[0072] As the outer cover 8 is closed, the second pressing wedge abuts against the front pressing wheel 40, and the sliding frame 43 moves on the placement tray 7. The sliding frame 43 drives the third elastic telescopic rod 42 to move, thereby driving the push plate 41 to move, so that the push plate 41 abuts against the film 9. During the pressing process, the rear side baffle 12 always abuts against the other end of the film 9 to prevent the film 9 from moving to the other side, thereby aligning the front and back of the film 9.

[0073] The third elastic telescopic rod 42 has an inflatable spring inside, which can be adjusted in length according to the length of the film 9. A limit block that cooperates with the sliding frame 43 is installed on the placement tray 7 to limit the position of the sliding frame 43 and prevent a large pressure from being generated between the push plate 41 and the film 9. Since the front part of the film 9 does not require any thrust during the transportation of the film 9, the push plate 41 only serves to align the film 9.

[0074] Example 2: This example differs from the example 1 in that: Figure 1-Figure 4 、 Figure 6-Figure 7 、 Figures 9-11 、 Figure 18-19 The outer cover 8 is equipped with an upper extrusion assembly 35 that cooperates with the film 9; the upper extrusion assembly 35 includes a plurality of second elastic telescopic rods 36 fixedly mounted on the top of the inner part of the outer cover 8, and the telescopic ends of the plurality of second elastic telescopic rods 36 are fixedly mounted with a support plate 37, and two shafts are rotatably mounted on the support plate 37, and a rubber wheel 38 that cooperates with the film 9 is fixedly mounted on the two shafts. A second motor 39 with two drive shafts is fixedly mounted on the support plate 37, and the two drive ends of the second motor 39 are respectively fixedly connected to the corresponding shafts.

[0075] When the outer cover 8 is closed, the rubber wheel 38 will be against the upper part of the film 9, and the second elastic telescopic rod 36 will be compressed. When the film 9 needs to be conveyed, the second motor 39 is started, and the driving end of the second motor 39 rotates to drive the two rubber wheels 38 to rotate, thereby sending the top film 9 out of the film pile.

[0076] Cooperating with the lifting assembly, it can be ensured that the position where each film 9 is delivered from the film stack is at the same position.

[0077] The tray 5 is provided with a rear baffle 12 by a movable assembly, and the placement plate 7 is provided with a through hole that matches the rear baffle 12 for passage of the rear baffle 12;

[0078] The moving assembly includes a limit frame fixedly mounted on the tray 5, a rear baffle 12 and a limit frame being slidably connected, two connecting rods 25 fixedly mounted on the rear baffle 12, a tooth plate 29 fixedly mounted on each of the two connecting rods 25, a gear 30 meshing with the corresponding tooth plate 29 being rotatably mounted on both sides of the tray 5, and two incomplete tooth plates 31 matching the corresponding gears 30 being fixedly mounted on the outer cover 8.

[0079] When the outer cover 8 just starts to close, the rear baffle 12 always extends out of the placement tray 7 and is flush with the upper part of the film 9. At this time, all films 9 can be blocked. As the outer cover 8 closes, the rear baffle 12 always remains stationary. When the outer cover 8 is close to closing, the front, back, left, and right sides of the films 9 have been aligned. The incomplete tooth piece 31 just meshes with the gear 30. The outer cover 8 continues to rotate and close. The incomplete tooth piece 31 drives the gear 30 to rotate, thereby driving the tooth plate 29 to move. The tooth plate 29 drives the connecting rod 25 to move, thereby driving the rear baffle 12 moves toward the side close to the tray 5, and a visual inspection module is fixedly installed on the rear baffle 12. As the rear baffle 12 moves, the visual inspection module will detect the alignment of the films 9, and a prompt will appear after the detection meets the standard; when the outer cover 8 is closed, the incomplete tooth piece 31 is separated from the gear 30. At this time, the rear baffle 12 is reset under the action of the reset spring 33, and the rear baffle 12 continues to block the rear of the film 9. When conveying the film 9, under the action of the rear baffle 12, only one film 9 can be conveyed at a time.

[0080] The specific operating steps of this device are as follows:

[0081] First, open the cover 2, pull the tray 5 out of the film compartment 4, then open the outer cover 8, and then place the film 9 on the placement tray 7, and place it between the side extrusion assembly 10, the front extrusion assembly 11 and the rear baffle 12;

[0082] After placement is completed, the outer cover 8 is closed so that the bottom of the outer cover 8 is in contact with the bottom of the tray 5. As the outer cover 8 is closed, the side squeezing components 10 and the front squeezing components 11 are triggered to operate. The side squeezing components 10 squeeze and align the two sides of the film 9, and the front squeezing components 11 cooperate with the rear baffle 12 to align the front and back of the film 9.

[0083] After being aligned by the side extrusion assembly 10 and the front extrusion assembly 11, the film 9 is aligned up and down, and after the outer cover 8 is closed, the upper extrusion assembly 35 presses and smoothes the upper part of the film 9 to prevent the film 9 from arching, and after the film 9 is aligned, the film 9 is transported by the upper extrusion assembly 35.

[0084] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
