[0002] In traditional instruction sheet paper bagging machines, to achieve automatic bagging of instruction sheet papers, the instruction sheet papers need to be automatically conveyed. However, in traditional bagging machines, due to the relatively long transfer channel for the instruction sheet papers, the planar friction time between the instruction sheet papers and the transfer channel is relatively long, which will inevitably cause certain scratches or abrasions on the surface of the paper sheets, thereby affecting the product quality and failing to meet the quality requirements of customers.

[0065] For the realization of the object of the present invention, its functional features and excellent effects, further explanations will be given below in conjunction with specific embodiments and the drawings. Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0069] In a traditional instruction manual sheet bagging machine, to achieve automatic bagging of instruction manual sheets, the instruction manual sheets need to be automatically conveyed. In the traditional bagging machine, due to the long transfer channel of the instruction manual sheets, the planar friction time between the instruction manual sheets and the transfer channel is long, which will inevitably cause certain scratches or abrasions on the surface of the sheets, thus affecting the product quality and not meeting the quality requirements of customers. In view of this, the present invention provides a process and device for transferring instruction manual sheets. Figures 1 to 14 This is an embodiment of the process and device for transferring instruction manual sheets provided by the present invention.

[0070] Please refer to Figure 1 , and the first embodiment of the process for transferring instruction manual sheets is proposed, which specifically includes the following steps:

[0071] S1. Transfer the sheet to the shunt station 11;

[0072] In this embodiment, there are various forms of transferring the sheet, such as through a conveyor belt, conveyor rollers, etc., which are not limited herein. In one embodiment, for example, the instruction manual sheet 5 can be conveyed through a double pulley structure and transmitted through two spaced belts, so that the contact surface between the instruction manual sheet 5 and the belt is less, thereby reducing friction.

[0073] S2. The sheet clamping mechanism 3 clamps the sheet at the shunt station 11 to the corresponding sheet waiting station.

[0074] In this embodiment, when moving the sheet from the shunt station 11 to the sheet waiting station, it is mainly transferred by clamping, so that there is no relative movement between the sheet and the sheet clamping mechanism 3, thereby reducing the friction between the sheet and the sheet clamping mechanism 3 and preventing the sheet from being worn. The setting form of the sheet clamping mechanism 3 is not limited herein, and any setting form that can clamp the sheet and move the sheet from the shunt station 11 to the sheet waiting station should fall within the protection scope of the present invention.

[0075] In the technical solution provided by the present invention, after the sheet is transferred to the shunt station 11, the sheet can be transferred from the shunt station 11 to the sheet waiting station by clamping. Compared with the traditional method of moving the sheet by pushing, the technical solution provided by the present invention can ensure that there is no relative displacement between the sheet and the sheet clamping mechanism 3 during the shunting process, avoid friction between the sheet and the sheet clamping mechanism 3, thereby ensuring that the sheet is not worn and guaranteeing the quality of the sheet during the transfer process and improving the finished product quality.

[0076] Further, please refer to Figure 2 , and the second embodiment of the process for transferring instruction manual sheets is proposed.

[0077] When the sheet clamping mechanism 3 includes a clamping structure, the step S2 specifically includes:

[0078] S21. Clamp the sheet at the shunting station 11 in the up-and-down direction through the clamping structure, and align the sheet at the same time;

[0079] It should be noted that, for reference, Figure 4 , the instruction sheet 5 is generally square. To place the sheet neatly in the box bag, before placing it in the box bag, the sheet needs to be aligned to achieve a better bagging effect. Specifically, when the clamping structure clamps the sheet in the up-and-down direction, the sheet is limited in the up-and-down direction. Then, the sheet also needs to be limited in other directions for alignment. The alignment of the sheet also includes aligning the sheet in the left-and-right direction and aligning the sheet in the front-and-back direction, so that the instruction sheet 5 can be neatly placed in the box bag.

[0080] S22. Transfer the aligned sheet from the shunting station 11 to the sheet waiting station.

[0081] After the instruction sheet 5 is aligned in the front-and-back direction and the left-and-right direction, the instruction sheet 5 is clamped by the clamping structure in the up-and-down direction. The clamping structure moves from the shunting station 11 to the sheet waiting station, so as to transfer the instruction sheet 5 from the shunting station 11 to the sheet waiting station.

[0082] When transferring the instruction sheet 5, the instruction sheet 5 can also be aligned, so that the placement of the instruction sheet 5 is neater and the surface of the sheet can be protected from being worn.

[0083] Further, for reference, Figure 3 , a third embodiment of the instruction sheet transfer process is proposed.

[0084] In this embodiment, the sheet is transferred to the shunting station 11 through the sheet conveying mechanism 2; the clamping structure is movably arranged between the shunting station 11 and the waiting station, and includes a receiving plate 321 and a pressing plate 323 arranged above the receiving plate 321. When the clamping structure moves to the shunting station 11, the receiving plate 321 is located at the end of the sheet conveying mechanism 2 in the conveying direction, and has a front side close to the sheet conveying mechanism 2 and a rear side opposite to the front side; the initial height of the receiving plate 321 when receiving the material is not higher than the height of the conveying end of the sheet conveying mechanism 2. The step S21 specifically includes:

[0085] S211. The sheet transfer mechanism 2 transfers the sheet to the receiving plate 321, causing the sheet to align with the rear side of the receiving plate 321.

[0086] S212. Move the receiving plate 321 closer to the pressing plate 323, so that the sheet on the receiving plate 321 is clamped within the left - right limiting structure 324 of the pressing plate 323, enabling the sheet to be aligned in the left - right direction.

[0087] It should be noted that there are various ways to align the sheet of the specification in the front - rear direction and the left - right direction. For example, when the sheet is transferred to the shunting station 11 by the sheet transfer mechanism 2, the clamping structure is movably arranged between the shunting station 11 and the waiting station. The clamping structure includes a receiving plate 321 and a pressing plate 323 arranged above the receiving plate 321. When the clamping structure moves to the shunting station 11, the receiving plate 321 is located at the end of the sheet transfer mechanism 2 and has a front side close to the sheet transfer mechanism 2 and a rear side opposite to the front side. And when setting the initial height of the receiving plate 321 for receiving the sheet to be not higher than the height of the transfer end of the sheet transfer mechanism 2, the initial height is the height of the front side of the receiving plate 321 when the receiving plate 321 is at the transfer end of the sheet transfer mechanism 2 to prepare for receiving the sheet, so that the sheet can be transferred to the receiving plate 321 under the action of the transfer force of the sheet transfer mechanism 2.

[0088] For example, when the initial height of the receiving plate 321 is set to be lower than the height of the end of the sheet transfer mechanism 2, when the sheet falls from the sheet transfer mechanism 2 onto the receiving plate 321, it can fall in a parabolic shape. Under the action of the transfer inertia force and its own gravity of the sheet transfer mechanism 2, the sheet aligns with the rear side of the receiving and pressing plate, so as to avoid scattering onto the receiving plate 321. And the sheet can be further moved by an external mechanism or manually to align the sheet in the front - rear direction. Further, the sheet is aligned in the left - right direction by the limiting structure 324 on the pressing plate 323, so that the sheet is neatly arranged. When the sheet on the receiving plate 321 abuts against the pressing plate 323, the sheet is clamped between the receiving plate 321 and the pressing plate 323. Then, the receiving plate 321 and the pressing plate 323 clamp the sheet and move it, so that the sheet is aligned while being clamped, improving the bagging quality of the sheet.

[0089] Furthermore, a fourth embodiment of the sheet transfer process of the specification is proposed.

[0090] In this embodiment, a baffle 322 protrudes from the rear side of the receiving plate 321, and the receiving plate 321 is inclined downward in the direction from the front side to the rear side.

[0091] In the step of the sheet transfer mechanism 2 transferring the sheet onto the receiving plate 321 so that the sheet abuts against the rear side of the receiving plate 321, the sheet transferred from the sheet transfer mechanism 2 onto the receiving plate 321 moves and abuts against the baffle 322 under the action of its own gravity.

[0092] By setting the receiving plate 321 to be inclined, automatic alignment of the sheet in the front-back direction can be achieved. The alignment method is simple and easy to implement.

[0093] Further, a fifth embodiment of the sheet transfer process of the specification is proposed.

[0094] The difference between this embodiment and the fourth embodiment lies in the different methods of aligning the sheet in the front-back direction.

[0095] In this embodiment, when a baffle 322 protrudes from the rear side of the receiving plate 321 and the receiving plate 321 is horizontally arranged; the steps of S211 specifically include:

[0096] The sheet is transferred from the sheet transfer mechanism 2 onto the receiving plate 321 at the splitting station 11.

[0097] The receiving plate 321 is rotated so that the front side of the receiving plate 321 is higher than the rear side, causing the sheet to move backward to abut against the baffle 322, so that the sheet is aligned in the front-back direction.

[0098] In this embodiment, for example, when the receiving plate 321 is at the same height as the end of the sheet transfer mechanism 2, the sheet is directly translated onto the receiving plate 321 and cannot be automatically aligned to the rear side of the receiving plate 321. Therefore, the receiving plate 321 can be rotatably arranged, and by rotating the receiving plate 321, the front end of the receiving plate 321 is lifted, so that the sheet on the receiving plate 321 abuts against the rear side of the receiving plate 321. The alignment method and clamping method of the sheet in the left-right direction are the same as those in the previous embodiment and will not be repeated here.

[0099] Further, a sixth embodiment of the sheet transfer process of the specification is proposed.

[0100] In this embodiment, the splitting of the specification sheet 5 is achieved by the transfer method in the above embodiment.

[0101] In this embodiment, the steps of S2 specifically include:

[0102] The sheet clamping mechanism 3 moves towards the first waiting station 12, and one of the two clamping structures clamps the sheet from the sheet waiting station, and the other places the sheet at the first waiting station 12;

[0103] The sheet clamping mechanism 3 moves towards the second waiting station 13, and one of the two clamping structures places the sheet at the second waiting station 13, and the other clamps the sheet from the sheet waiting station.

[0104] It should be noted that the method of transferring the specification sheet 5 by clamping can be applied to various places with high requirements for the surface quality of the sheet. Specifically, refer to Figure 5 , when diverting the specification sheet 5, due to the relatively long traditional diversion channel, the surface friction time of the specification sheet 5 with the channel is relatively long. In the present invention, when the sheet waiting station includes a first waiting station 12 and a second waiting station 13, and the first waiting station 12 and the second waiting station 13 are respectively arranged on both sides of the diversion station 11, the sheet clamping mechanism 3 can include two clamping structures; thus, when the sheet clamping mechanism 3 moves towards the first waiting station 12, one of the clamping structures moves to the first waiting station 12, and at the same time the other clamping structure moves to the diversion station 11 to clamp the sheet; similarly, when the sheet clamping mechanism 3 moves towards the second waiting station 13, when one of the clamping structures moves to the second waiting station 13, the other clamping structure moves to the diversion station 11 to clamp the sheet, and the two clamping structures sequentially transfer the specification sheet 5 from the diversion station 11 to the first waiting station 12 and the second waiting station 13 to divert the specification sheet 5, which can accelerate the bagging speed of the specification sheet 5 and improve work efficiency.

[0105] The specification sheet transfer process provided by the present invention transfers the specification sheet 5 from the diversion station 11 to the sheet waiting station by clamping, so that the sheet can be clamped between the receiving plate 321 and the pressing plate 323, so that there is no relative movement between the sheet and the receiving plate 321 and the pressing plate 323, no friction is generated, the surface of the sheet is not worn, and the quality of the specification sheet 5 is ensured.

[0106] The following describes the specification sheet transfer process in conjunction with a specific device.

[0107] Please refer to Figures 6 to 9, the present invention provides a specification sheet transfer device 100 for transferring sheets according to the above-mentioned specification sheet transfer process. Specifically, the specification sheet transfer device 100 includes a base 1, a sheet transfer mechanism 2, and a sheet clamping mechanism 3. The base 1 is provided with a loading station, a shunting station 11, and a sheet waiting station. The arrangement directions of each station can be reasonably arranged according to the specific production line layout, which is not limited herein; the sheet transfer mechanism 2 is arranged on the base 1 and is used to transfer the sheet from the loading station to the shunting station 11; the sheet clamping mechanism 3 includes a clamping structure movably arranged on the base 1, and the clamping structure is used to clamp the sheet transferred to the shunting station 11 and transfer it to the sheet waiting station.

[0108] It should be noted that the sheets are mainly the specification sheets 5 of 3C products, such as the specification sheets 5 of products such as mobile phones and computers. In the following description, the specification sheets 5 of mobile phones will be mainly used as an example for illustration, and other types can be referred to for implementation. Refer to Figure 4 , the specification of a mobile phone is generally composed of a piece of paper folded into multiple layers of stacked papers, and a SIM card pin fixing piece is provided on the outermost side. The SIM card pin is fixed on the fixing piece, and the SIM card pin is very likely to scratch the sheet transfer mechanism during the movement.

[0109] In the technical solution provided by the present invention, the sheet transfer mechanism 2 transfers the sheet from the loading station to the shunting station 11 to prepare for shunting. By providing the sheet clamping mechanism 3, the sheet can be clamped and transferred from the shunting station 11 to the sheet waiting station to prepare for bagging. During the shunting process, the sheet is clamped and moved by the clamping structure, so that there is no relative movement between the sheets and between the sheet and the clamping structure, thereby avoiding wear of the sheet during the movement and effectively ensuring the quality of the sheet.

[0110] There are various setting forms of the sheet transfer mechanism 2, such as conveyor belt transfer, roller transfer, etc., which are all prior arts and will not be specifically described herein. In this embodiment, since the SIM card pin is very likely to scratch the sheet transfer mechanism during the movement, the sheet transfer mechanism 2 can be set as a double conveyor belt transfer with an intermediate interval, so that the SIM card pin is located between the intervals of the double conveyor belts, so as to prevent the SIM card pin from scratching the conveyor belt and also reduce the friction between the conveyor belt and the sheet.

[0111] There are various setting forms of the clamping structure. In one embodiment, the clamping structure can be set as a clamping jaw to clamp and transfer the sheet on the sheet transfer mechanism 2.

[0112] To ensure the flatness of the sheet, in another embodiment, it can be combined with Figure 7 and Figure 9, the clamping structure may include a material receiving plate 321 and a material pressing plate 323. The material receiving plate 321 is movably arranged on the base 1 and has a moving stroke for reciprocating movement between the shunting station 11 and the material sheet waiting station; the material pressing plate 323 is movably arranged on the base 1 and is located above the material receiving plate 321. The material pressing plate 323 has a moving stroke for reciprocating movement between the shunting station 11 and the material sheet waiting station; wherein, the material receiving plate 321 further has a vertical moving stroke to have a clamping position for moving upward to cooperate with the material pressing plate 323 to clamp the material sheet in the vertical direction, and a separating position for moving downward to separate from the material pressing plate 323.

[0113] In this embodiment, the material receiving plate 321 may be provided with a hollow structure so that when the material sheet falls onto the material receiving plate 321, the pin on the material sheet can correspond to the hollow part to prevent the pin from scratching the material receiving plate 321. Specifically, the material receiving plate 321 may include a main material receiving board, a first material receiving fork and a second material receiving fork located on one side of the main material receiving board close to the material sheet conveying mechanism 2. The first material receiving fork and the second material receiving fork are arranged in parallel at intervals. When the material sheet falls onto the material receiving plate 321, the pin on the material sheet can be accommodated between the intervals of the first material receiving fork and the second material receiving fork.

[0114] The clamping structure can not only transfer the material sheet, but also align the material sheet at the same time to make the material sheet neater for bagging. Specifically, the material receiving plate 321 has a front side arranged close to the material sheet conveying mechanism 2 and a rear side opposite to the front side. A baffle 322 protrudes upward from the rear side of the material receiving plate 321, and the material receiving plate 321 is arranged to be inclined downward in the direction from the front side to the rear side. After the material sheet falls onto the material receiving plate 321, it can slide from the front side to the rear side under the action of its own gravity and thus lean against the baffle 322 to align the material sheet in the front-rear direction.

[0115] Furthermore, for the alignment of the material sheet in the left-right direction, reference can be made to Figure 9, a limiting structure 324 is formed on one side of the pressure plate 323 facing the material receiving plate 321. The limiting structure 324 includes a first limiting protrusion 3241 and a second limiting protrusion 3242 protruding from the bottom of the material receiving plate 321. The first limiting protrusion 3241 and the second limiting protrusion 3242 are arranged oppositely along the left-right direction of the base 1. After the sheet is abutted against the baffle 322, the first driving structure drives the material receiving plate 321 to move upward along the base 1 to approach the pressure plate 323, and at the same time, the sheet is inserted into the space between the first limiting protrusion 3241 and the second limiting protrusion 3242, so as to align the sheet in the left-right direction by the first limiting protrusion 3241 and the second limiting protrusion 3242.

[0116] The setting form of the limiting structure 324 is not limited to the above one. To make the alignment of the sheet smoother, reference can be made to Figure 14 , the distance between the opposite side walls of the first limiting protrusion 3241 and the second limiting protrusion 3242 along the left-right direction can be set to gradually expand in the up-down direction, so that during the upward movement of the material receiving plate 321, the sheet on the material receiving plate 321 can be gradually aligned in the left-right direction.

[0117] The setting form of the pressure plate 323 is not limited to the above one. In another embodiment, reference can be made to Figure 12 , the pressure plate 323 can be set as a limiting groove, and the bottom of the limiting groove can be used to clamp the sheet with the material receiving plate 321. The first limiting protrusion 3241 and the second limiting protrusion 3242 can be formed on the two side walls of the limiting groove along the left-right direction to limit the sheet in the left-right direction.

[0118] In another embodiment, reference can be made to Figure 13 , the pressure plate 323 can also be provided with a plurality of limiting blocks arranged at intervals along the left-right direction of the base 1, and the material receiving plate 321 cooperates with the plurality of limiting blocks to clamp the sheet.

[0119] And according to the different positions of the material receiving plate 321, the setting method of the material receiving plate 321 can also be different.

[0120] In one embodiment, it can be combined with Figure 8 and Figure 10, when the set height of the receiving plate 321 is lower than the set height of the transfer end of the sheet transfer mechanism 2, the sheet drops from the sheet transfer mechanism 2. Due to a certain height difference and the sheet transfer mechanism 2 having a certain transfer speed, when the sheet drops from the sheet transfer mechanism 2, it will fall onto the receiving plate 321 in a parabolic shape. And when the front side of the receiving plate 321 is set higher than the rear side, the sheet will move towards the rear side under the action of inertia and its own gravity to align with the baffle 322.

[0121] In another embodiment, reference may be made to Figure 11 , when the set height of the receiving plate 321 is flush with the set height of the transfer end of the sheet transfer mechanism 2, the sheet will be transferred from the sheet transfer mechanism 2 to the receiving plate 321 in a translation manner. At this time, the receiving plate 321 can be rotatably arranged on the base 1. The sheet clamping mechanism 3 further includes a rotation driving structure connected to the receiving plate 321. The rotation driving structure is used to drive the receiving plate 321 to rotate by a certain angle so that the height of the front side of the receiving plate 321 is higher than the height of the rear side of the receiving plate 321, so that the sheet on the receiving plate 321 can be aligned with the baffle 322 to regularize the sheet in the front-rear direction.

[0122] In this embodiment, the sheet transfer device 100 of the specification is mainly used to divert the sheets so that the sheets can be quickly bagged to save bagging time. Specifically, in combination with Figures 5 to 7 , the sheet waiting stations include a first waiting station 12 and a second waiting station 13 arranged along the left-right direction of the base 1, and the first waiting station 12 and the second waiting station 13 are respectively located on both sides of the diversion station 11; the clamping structures include a first clamping structure 31 and a second clamping structure 32. The first clamping structure 31 is arranged corresponding to the first waiting station 12, and the second clamping structure 32 is arranged corresponding to the second waiting station 13. The two clamping structures can transfer the sheets in sequence. When the receiving plate 321 of the first clamping structure 31 transfers the sheet from the diversion station 11 to the first waiting station 12, the receiving plate 321 of the second clamping structure 32 moves from the second waiting station 13 to the diversion station 11. When the receiving plate 321 of the first clamping structure 31 is reset from the first waiting station 12 to the diversion station 11, the receiving plate 321 of the second clamping structure 32 moves from the diversion station 11 to the second waiting station 13. The two clamping structures cooperate to pick up the sheets to respectively transfer the sheets at the diversion station 11, and the working efficiency is higher.

[0123] Furthermore, the sheet clamping mechanism 3 further includes an up-and-down driver 33 and a left-and-right driver 34; there are two up-and-down drivers 33, and the two up-and-down drivers 33 are respectively drivingly connected to the receiving plates 321 of the first clamping structure 31 and the receiving plates 321 of the second clamping structure 32 in a one-to-one correspondence; the instruction sheet transfer device 100 further includes a connecting plate 4, the connecting plate 4 connects the receiving plates 321 of the first clamping structure 31 and the receiving plates 321 of the second clamping structure 32, and the left-and-right driver 34 is drivingly connected to the connecting plate 4, so that one left-and-right driver 34 can be saved, and it can be ensured that the receiving plates 321 of the first clamping structure 31 and the receiving plates 321 of the second clamping structure 32 can move synchronously, and the stability is better.

[0124] Moreover, in order to ensure the stability of sheet clamping, the pressing plate 323 and the receiving plate 321 should maintain the synchronization of movement. Specifically, the clamping structure further includes a support seat 35 provided on the connecting plate 4, and the pressing plate 323 is provided on the support seat 35, so as to drive the connecting plate 4 to move left and right along the base 1 through the left-and-right driver 34, so that the two receiving plates 321 and the pressing plate 323 located on the connecting plate 4 can move left and right synchronously, making the transfer of the sheet more stable.

[0125] In this embodiment, the specific working principle of the specification sheet transfer device 100 is as follows: The sheet is transferred to the shunting station 11 through the sheet transfer mechanism 2. The sheet transfer mechanism 2 can be provided with a conveyor belt for transfer. When the height of the receiving plate 321 is set to be not higher than the height of the conveyor belt, the height of the front side of the receiving plate 321 is higher than that of the rear side. After the sheet is dropped from the conveyor belt onto the receiving plate 321 of the first clamping structure 31 provided corresponding to the shunting station 11, the sheet leans against the rear baffle 322 under the action of inertia and its own gravity. The up-down driver 33 drives the receiving plate 321 of the first clamping structure 31 to move upward to approach the pressing plate 323, and at the same time, under the action of the limiting structure 324, the sheet is aligned in the left-right direction during the upward movement. Then, the left-right driver 34 drives the connecting plate 4 to move, so that the receiving plate 321 of the first clamping structure 31 moves to the first waiting station 12. At the same time, the receiving plate 321 of the second clamping structure 32 moves from the second waiting station 13 to the shunting station 11. At this time, the sheet falls from the conveyor belt onto the receiving plate 321 of the second clamping structure 32. The receiving plate 321 of the second clamping structure 32 repeats the above actions of the receiving plate 321 of the first clamping structure 31 and resets from the shunting station 11 to the second waiting station 13. At the same time, the receiving plate 321 of the first clamping structure 31 resets from the first waiting station 12 to the shunting station 11 to complete one shunting. By repeating the above process, the sheet can be shunted to save the time for bagging the sheet.
