Description

Technical Field

[0001] The present invention relates to a flap unfolding device with an anti-scratch function, and more particularly to a flap unfolding device with an anti-scratch function. The device can form a gap by adsorbing a cover integrally formed with a flap to one side through an adsorption device, so that the remaining printed matter except the cover integrally formed with the flap can be lifted to a certain height, thereby forming a space for the flap to be unfolded. The flap can be unfolded by inserting a flap unfolding rod into the gap between the cover and the flap. The device can also prevent the quality of the printed matter from being deteriorated due to scratches on the surface by reducing friction when the printed matter moves. Background Art

[0002] Generally speaking, a packaging machine refers to a machine that automatically packages various products such as packaging objects with a transparent film, namely, packaging vinyl. As described above, the packaging vinyl can cover the entire packaging object, so its packaging efficiency is high, but when the packaging object is used, the packaging vinyl must be removed and discarded, which may cause environmental pollution.

[0053] Next, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it should be understood that the present invention can be implemented in many different forms and is not limited to the described embodiments.

[0054] Figure 1a This is a front view showing the overall structure of the cuff expansion device to which the present invention is applicable. Figure 1bThis is a plan view illustrating the overall structure of a flap unfolding device applicable to the technology of the present invention. The flap unfolding device 1 of the present invention generally comprises: a transfer tray assembly 40, which stands upright a printed matter integrally formed with a flap at a certain angle and moves it; an adsorption device 30, which forms a gap (space) between the printed matter and the cover by adsorbing the cover of the printed matter moved from the transfer tray assembly 40; a space forming assembly 10, which moves the printed matter further to one side by introducing the gap (space) between the printed matter and the cover to further expand the gap (space); and a flap unfolding assembly 20, which is used to unfold the flap integrally formed with the cover and folded.

[0055] The transfer tray assembly 40 is as follows Figure 2a As shown, it is formed in a circular cross-sectional shape. When the printed matter transferred from the saddle stitching machine is supplied, one side will contact the transfer assembly 43 and the other side will be placed on the transfer tray component 41, thereby moving to one side on the desktop.

[0056] When the printed matter moves horizontally instead of at a certain tilt angle as in the present invention, a large number of scratches will be formed on the printed matter cover due to friction, resulting in a problem of reduced product quality. By preventing the above-mentioned problems, the quality of the product can be maintained.

[0057] The structure of the transfer tray assembly 40 is as follows Figure 2a as well as Figure 2b As shown, a transfer tray component 41 composed of a print position adjustment portion 41-2 which is integrally formed with a linear moving portion 41-1 which stands upright and moves linearly at a certain angle and whose angle is gradually reduced so that the printed matter is horizontal is fixedly installed on the outer side of the desktop. In the front part of the transfer tray component 41, a holding component P installed at a certain interval is connected to a chain, and the chain is rotated by a driving motor not shown in the figure.

[0058] When the chain is rotated and moved by the rotation of the driving motor, Figure 2b As shown in FIG. 1 , one side supplied from the saddle stitching machine will be clamped on the holding member P, so that the printed matter on one side of the transfer tray member 41 moves along the transfer tray member 41. At this time, the angle of the transfer tray member 41 is in the range of 5 to 30 degrees. In the initial stage, it stands upright and moves at 5 to 30 degrees, and then as shown in FIG. Figure 2b As shown, the angle of the printed matter gradually decreases until it lies horizontally during the process of passing through the printed matter position adjusting unit 41 - 2 .

[0059] More specifically, when the printed material moves from the saddle stitching machine, it will be placed in position ① as shown in the accompanying drawing. At this time, one end of the printed material will rest on the linear moving portion 41-1 and form a certain angle, while the hem will remain folded to the inside of the printed material.

[0060] When the transfer assembly 43 formed by installing the holding part P on the chain is working, the printed matter will move from the above-mentioned position ① to the above-mentioned position ②, and when the adsorption device 30 inhales air, the cover will move to the side of the adsorption device 30 together with the air and be adsorbed to the surface of the adsorption device 30, thereby forming a gap between it and the printed matter.

[0061] The suction device 30 sucks air through holes formed on the surface of a cylindrical suction roller that rotates by the rotational force of a driving motor, thereby sucking the cover through the holes, and the suction device is connected to a vacuum device (not shown). Figure 2b As shown, one side of the printed matter moving on the linear moving portion 41-1 can be sucked in, thereby stretching it open and thereby forming a gap between the printed matter and the cover.

[0062] At this time, the space forming component 10 will be introduced into the gap formed by the adsorption device 30 and further move the printed matter, thereby further stretching the space between the printed matter and the cover and thereby forming a larger gap.

[0063] In addition, if Figure 2b As shown, when the cuff is unfolded to an angle greater than 90° but less than 180° by the cuff unfolding assembly 20, the cuff unfolded to a certain angle will be embedded in the lower part of the anti-reset guide 44 installed at a staggered angle greater than 90° but less than 180°, thereby preventing the cuff from being reset.

[0064] The structure of the space forming component 10 is as follows Figure 6a as well as Figure 6b As shown, the fixed frame 12 is mounted on a height adjustment handle 11 which is rotatably mounted on the space forming member 10 so as to adjust the distance from the printed matter moving on the desk by adjusting the height of the space forming member 10 in the rotation direction.

[0065] The height adjustment handle 11 is connected with a screw member 13 that rotates in the same direction as the rotation direction of the height adjustment handle and is rotatably axially mounted to the fixed frame 12. It is preferable to install a handle locking device 11-1 between the height adjustment handle 11 and the screw member 13 to prevent the height adjustment handle 11 from loosening.

[0066] The handle locking device 11-1 of the height adjustment handle 11 can make the height adjustment handle rotate freely when the rod is rotated in one direction, and keep the height adjustment handle in a non-rotatable state when the rod is rotated in the opposite direction. The structure of the handle locking device 11-1 is a general locking device, so the description related to its structure will be omitted.

[0067] In addition, a height adjusting component 14 that moves up and down along the rotation direction of the screw component 13 is installed in the screw component 13, a connecting component for adjusting the angle of the space forming component 10 is installed in the height adjusting component 14, and a space forming component 15 that forms a space for the cuff to be expanded by expanding the gap formed between the printed matter and the cuff is installed in the space forming connecting component 16.

[0068] The space forming connecting component 16 includes: a bracket 16-1, which is formed with a fixing hole fixed to the height adjustment component 14; and an angle adjustment component 16-2, which is equipped with a long hole whose center is consistent with the fixing hole of the bracket 16-1, and is equipped with a combining hole for the retaining part 15-3 to be combined; so that the screw passing through the long hole can be screwed into the fixing hole.

[0069] At this time, the space forming member 15 is as follows Figure 5 As shown, when a space forming rod 15-2 having a sharp needle at the end inserted between the printed matter and the hem is inserted into the gap, the printed matter can be lifted by the space forming rod 15-2 to a height corresponding to the diameter of the space forming rod 15-2, thereby supporting the printed matter lifted upward by the support plate 15-1 equipped on the space forming rod 15-2.

[0070] Furthermore, it further includes a holding portion 15 - 3 that fixes the space forming rod 15 - 2 and performs fine angle adjustment by connecting with the angle adjustment member 16 - 2 .

[0071] In addition, the mounting structure of the support plate 15-1 for supporting the printed matter is as follows: Figure 1a as well as Figure 5 As shown, the effect of lifting the printed matter is provided by the wider portion of the flat plate shape, and the support plate 15-1 is installed in a manner such that the wider plate portion can be seen when observed from a plane. In addition, in order to allow the printed matter lifted by the needle to be slowly unfolded to a certain angle, the support plate 15-1 is also installed at a certain tilt angle.

[0072] In addition, when the space forming component 10 is introduced into the gap formed by the adsorption device 30 and further moves the printed matter, thereby further stretching the printed matter and the cover to form a larger gap, the folded flap will be unfolded by the flap unfolding component 20.

[0073] The cuff expansion assembly 20 is as follows Figure 3a as well as Figure 3b As shown, the fixing frame 22 is mounted on the height adjustment handle 21 which is rotatably mounted on the height adjustment member 25 to adjust the distance from the printed matter moved on the desk by adjusting the height of the flap expansion member 25 along the rotation direction.

[0074] The height adjustment handle 21 is connected with a screw member 23 that rotates in the same direction as the rotation direction of the height adjustment handle 21 and is rotatably axially mounted to the fixed frame 22. It is preferable to install a handle locking device 21-1 between the height adjustment handle 21 and the screw member 23 to prevent the height adjustment handle 21 from loosening.

[0075] The handle locking device 21-1 can make the handle 21 rotate freely when the rod is rotated in one direction, and keep the height adjustment handle 21 in a non-rotatable state when the rod is rotated in the opposite direction. The structure of the handle locking device 21-1 is a general locking device, so the description related to its structure will be omitted.

[0076] In addition, a height adjustment member 24 is installed in the screw member 23 so as to move up and down along the rotation direction of the screw member 23 , and because the height adjustment member 24 moves along the guide rod installed on the fixed frame 22 , it can be prevented from shaking.

[0077] A flap connecting component 26 for adjusting the angle of the flap unfolding component 25 is installed in the height adjusting component 24, and a flap folding component 25 for unfolding the flap integrally formed with the cover and folded is installed in the flap connecting component 26.

[0078] The cuff connecting component 26 includes: an angle adjustment component 26-2, equipped with a center and a Figure 6b The bracket 26 - 1 having a fixing hole is formed with a fixing hole that is consistent with the long hole, and is equipped with a coupling hole for coupling with the holding portion 25 - 3 ; thus, a screw passing through the long hole can be screwed into the fixing hole.

[0079] At this time, the cuff expansion member 25 is as shown in FIG. Figure 4 As shown, an anti-reset plate is fixedly installed to prevent the opened flap from resetting to the side of the printed matter by elastic force and maintain a certain angle after the flap is opened by a flap opening rod 25-2 formed with a sharp needle at the end inserted between the flaps formed integrally with the cover and folded, and also includes: a retaining portion 25-3, which performs fine angle adjustment by connecting with the angle adjustment component 26-2 while fixing the flap opening rod.

[0080] Regarding the installation structure of the anti-reset plate 25-1, the wider portion of the flat plate is upright in the vertical direction, and is installed in a manner of forming a certain angle so that the cuff 90 can be expanded to more than 90 degrees.

[0081] The flap unfolding device 1 of the present invention structured as described above can work with two functions, namely, a flap unfolding function of unfolding the flap folded and formed integrally with the cover, and a space forming function of forming a space for the flap to be unfolded by lifting the printed matter from the flap before unfolding the flap.

[0082] First, when the printed material transferred from the saddle stitching machine is moved horizontally, a large number of scratches are formed on the cover of the printed material due to friction, resulting in a problem of reduced product quality. In order to maintain the quality of the product by preventing the above-mentioned problem, the printed material is supplied in a tilted " / " state when viewed from the side of the transfer tray assembly.

[0083] When the printed matter is supplied in the " / " shape as described above, the upper end of the printed matter is supported by the transfer tray assembly, and the holding members installed at a certain interval are installed to the transfer assembly rotated by the drive motor, so that the printed matter supplied from the saddle stitching machine is stuck between the holding members, so that the printed matter is moved by the holding members during the chain drive process.

[0084] That is, although the printed matter moves by means of the holding member installed on the chain at the lower end, since one side of the upper end is placed on the transfer tray member, the other side of the printed matter will move with the transfer tray member.

[0085] During the movement on the linear moving portion of the transfer tray component fixedly mounted on the outer side of the desktop, when air is sucked in through the through hole of the adsorption device, the cover will be adsorbed to the surface of the adsorption roller, and a gap will be formed between the cover and the printed matter.

[0086] First, as a method of forming a space between the cuff and the printed matter, as shown in Figure 6, after the height adjustment handle 11 of the space forming component 10 is released from the locked state of the handle locking device 11-1 so that the height adjustment handle 11 can rotate freely, the height adjustment handle 11 can be rotated to rotate the screw component 13 connected to the height adjustment handle 11.

[0087] When the screw component 13 rotates, the height adjustment component 14 screwed with the screw component 13 will also move in the up and down directions. The reason for adjusting the height of the height adjustment component 14 is to move the needle of the space forming component 15 to a position where it can be inserted into the gap between the flap and the printed matter formed by adsorbing the cover with an integral flap by using an adsorption device and sucking it downward.

[0088] In addition, after completing the height adjustment as described above, the needle of the space forming component 15 will lift the remaining printed matter except the cover with an integral flap to a certain height while the printed matter moves, thereby forming a space for the flap to be unfolded, and move a distance equivalent to the diameter or width of the space forming rod 15-2. At this time, because the support plate 15-1 is fixedly mounted on the space forming rod 152, the printed matter can be supported.

[0089] The angle adjustment method of the space forming component 15 is as follows Figure 7 As shown, when the bolts passing through the fixing holes and the long holes and screwed into the bracket 16-1 are loosened, the angle adjustment component 16-2 can be freely moved, thereby rotating the angle adjustment component 16-2 with the bolts as the center point, and after the angle is adjusted, the bolts are re-engaged to fix the angle adjustment component 16-2.

[0090] After the space forming component 10 is set up as described above, when the operator drives the unspecified adsorption device and transfer device installed on the desktop, the cover with an integral flap will be deformed toward the side of the adsorption device and a gap will be formed between the cover with an integral flap and the printed matter. When the space forming rod 15-2 is inserted into the gap, the remaining printed matter except the cover with an integral flap will move a distance corresponding to the diameter or width. At this time, because the support plate 15-1 is fixedly mounted on the space forming rod 15-2, the printed matter can be supported and a space for the flap to be unfolded can be formed.

[0091] In addition, the opening function of the cuff can eliminate the weight of the printed matter stacked on the upper part of the cuff by the space forming component 15, and at the same time, a space is formed between the printed matter and the cuff, such as Figure 7 as well as Figure 8 As shown, the height-adjusting handle 21 can be unlocked to allow the height-adjusting handle 21 to rotate freely, and then the height-adjusting handle can be rotated to rotate the screw member 23 connected to the height-adjusting handle 21 together.

[0092] When the screw component 23 rotates, the height adjustment component 24 screwed with the screw component 23 will also move in the up and down direction. The reason for adjusting the height of the height adjustment component 24 is to quickly move the needle of the cuff expansion component 25 to a lower position compared to the lower end cover of the printed material moving along the desktop.

[0093] The reason why the needle of the cuff expansion component 25 is quickly moved to a lower position compared to the lower cover of the printed matter is that after a mounting hole for mounting the adsorption device is punched on the desktop surface, the adsorption device is installed at a lower position compared to the mounting hole.

[0094] By locating the adsorption device at a lower position compared with the desktop surface, the printed matter cover will be adsorbed and moved in a downward direction by the adsorption device, so that the needle moves to a position maximally close to the adsorption device.

[0095] As another height adjustment method, the operator can directly adjust the cuff expansion rod 25-2 fixed to the holding portion 25-3 by intuition, but this operation method has the problem of requiring high proficiency and excessive installation time. After the height adjustment of the cuff expansion component 25 is completed, the cuff connection component 26 connected to the height adjustment component 24 is used to adjust the angle of the needle entering the space (gap) between the cover and the cuff.

[0096] As a method for adjusting the angle of the needle after the height adjustment is completed as described above, the flap expansion component is allowed to enter the gap formed between the cover and the flap, such as Figure 3b As shown, when the bolts passing through the fixing hole and the long hole and screwed into the bracket 26-1 are loosened, the angle adjustment component 26-2 can be freely moved, so that the angle adjustment component 26-2 is rotated with the bolt as the center point, and after the angle is adjusted, the bolts are re-engaged to fix the angle adjustment component 26-2.

[0097] After the installation of the cuff expansion assembly 20 is completed as described above, when the operator drives the suction device and the unexplained transfer device installed on the table, the overlapping printed matter will be transferred on the table, and then the suction device equipped on the table will be driven to form a printed matter. Figure 2b The method shown enables the cover with the flap formed integrally therewith to be bent toward one side of the adsorption device and adsorbed thereon.

[0098] At this time, because the cover is sucked and moved downward, the flap formed integrally with the cover will also be pulled downward, thereby forming a space between the cover and the flap and allowing the needle of the flap expansion rod 25-2 to enter the space.

[0099] When the needle enters the space between the cover and the flap, the space will be further expanded, so that the flap folded by the anti-reset plate 25-1 installed on the flap unfolding rod 25-2 is separated from the printed matter and unfolded.

[0100] As stated Figure 2bAs shown, when moving from position ② to position ③, the cuff will be unfolded in the process of passing through the adsorption device 30, the space forming component 10 and the cuff unfolding component installed between the two positions.

[0101] When the cuffs are unfolded, Figure 8 As shown, the anti-reset plate 25-1 having a flat plate-shaped wider portion standing upright in the vertical direction is guided and slowly erected, so that the cuff is expanded to more than 90 degrees.

[0102] In the process of the print position adjustment section 41 - 2 , that is, from the above position ③ to positions ④ and ⑤, the angle of the print will gradually decrease until it reaches the horizontal level.

[0103] The reason why the position of the printed matter is adjusted to be horizontal is that in subsequent processes, the printed matter needs to be spread apart and thicker paper inserts in a flat plate-like form need to be introduced therein, and this horizontal state facilitates the execution of subsequent processes.

[0104] The present invention as described above is a very useful invention which can unfold the cuff formed integrally with the cover of the printed matter while preventing the unfolded cuff from being reset toward the printed matter by elastic force and maintaining a certain angle, and has the advantages of being easy to use and having a simple structure.
