[0002] For some industrial products, such as electrical appliances like refrigerators and air conditioners, instruction manuals need to be placed in the boxes before the boxes are sealed. This process requires manual picking of the instruction manuals and putting them into the boxes. Each production line of the product produces about 4,000 products per day on average, and at least 400 products per hour. Each production line requires workers to complete the action of putting the instruction manuals more than 400 times per hour. One putting action requires picking and placing actions. This process requires employees to reach out and turn around to pick up the instruction manuals and put them into the product boxes on the conveyor belt. High-frequency and high-intensity repetitive work causes strain on the employees' arms and waists. Instruction manuals belong to a kind of sheet material with a certain flexibility. At present, there are also some existing technologies that use automated equipment such as robotic arms to replace manual labor for putting the instruction manuals, but this not only results in high equipment costs but also low putting efficiency, and can only pick and place one by one. Summary of the Utility Model

[0003] To solve the problem of inconvenient putting of sheet-like items at present, the utility model proposes a sheet conveying device, which can realize the simultaneous conveying of two sheets, convey two sheets at different positions to the same position, thereby improving the conveying efficiency, and further provides an instruction manual dispenser.

Two grippers for gripping sheets are arranged on the transverse movement module and face both sides of the moving direction respectively. The grippers are controlled by a rotating mechanism to rotate relative to the transverse movement module, so that the grippers face one side of the guide rail or downward.

[0005] In some embodiments, the transverse movement module includes a vertical column, and the rotating mechanism includes a swing rod and a telescopic rod. The gripper is arranged on the swing rod. One end of the swing rod is rotatably connected to the column, the other end of the swing rod is rotatably connected to one end of the telescopic rod, and the other end of the telescopic rod is rotatably connected to the column.

[0006] In some embodiments, the swing rod is a bent rod with a bent portion at the end, and the gripper is fixed on the bent portion of the swing rod.

[0007] In some embodiments, the column is slidably arranged on the guide rail, and the column is controlled by a telescopic cylinder to move along the guide rail.

[0008] In some embodiments, it further includes bins located at both ends of the guide rail for placing the sheets. The lower end of the bin has a discharge port. The sheets are stacked vertically in the bin. A lifting suction cup corresponding to the discharge port is arranged below the bin.

[0009] In some embodiments, several guide wheels for supporting the edge of the sheet are arranged at the edge of the discharge port.

[0010] In some embodiments, the number of the lifting suction cups is multiple, and the lifting suction cups are arranged corresponding to different corners of the sheet.

[0011] In some embodiments, the lifting suction cup is provided with a pressure sensor.

[0012] The instruction sheet dispenser includes the above-mentioned sheet conveying device, and the sheet is a product instruction sheet.

[0013] In some embodiments, a conveying track for conveying the packing box and a level sensor for detecting whether the packing box is located below the clamping jaw are arranged below the guide rail.

[0023] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment

[0025] As Figure 1 、 2 shown in Figures 1, 2, 3, and 4, the sheet 4 conveying device applied to the instruction manual dispenser includes a guide rail 1 and a transverse movement module moving along the guide rail 1. Two clamping jaws for clamping the sheet 4 are arranged on the transverse movement module and face both sides of the moving direction respectively. The two clamping jaws are the left clamping jaw 2 and the right clamping jaw 3 respectively, so that the sheet 4 can be clamped from both ends of the guide rail 1. The clamping jaws are controlled by a rotating mechanism to rotate relative to the transverse movement module, so that the clamping jaws face one side of the guide rail 1 or downward, so as to place the sheet 4 clamped from both ends of the guide rail 1 below. The sheet 4 in this embodiment is the instruction manual to be put into the product packing box 14. The clamping jaw only needs to be a device that can realize the basic clamping action of simple opening and closing. The clamping jaw in this embodiment is controlled by the expansion and contraction of a clamping jaw cylinder.

[0026] The technical effects of adopting the above design are as follows: Since there are two grippers for gripping the sheet 4 on the transverse movement module, which are respectively oriented towards both sides of the movement direction, and the grippers are controlled by a rotating mechanism to rotate relative to the transverse movement module, the transverse movement module can move towards the left and right ends, so as to respectively grip the sheet 4 placed at the left and right ends or conveyed by other equipment. When the transverse movement module moves towards the left end and uses the left gripper 2 to grip the sheet 4 at the left end, the right gripper 3 is located above the product packaging box 14. The rotating mechanism can be used to make the right gripper 3 face down and open, so that the sheet 4 gripped by the right gripper 3 from the right end falls into the product packaging box 14 below. Similarly, when the transverse movement module moves towards the right end and uses the right gripper 3 to grip the sheet 4 at the right end, the left gripper 2 is located above the product packaging box 14. The rotating mechanism can be used to make the left gripper 2 face down and open, so that the sheet 4 gripped by the left gripper 2 from the left end falls into the product packaging box 14 below.

[0027] The transverse movement module includes a vertical column 5. The rotating mechanism includes a swing rod 7 and a telescopic rod 6. The gripper is arranged on the swing rod 7. One end of the swing rod 7 is rotatably connected to the column 5, the other end of the swing rod 7 is rotatably connected to one end of the telescopic rod 6, and the other end of the telescopic rod 6 is rotatably connected to the column 5. The telescopic rod 6 can be a cylinder.

[0028] The technical effects of adopting the above design are as follows: The column 5, the swing rod 7 and the telescopic rod 6 form a triangular mechanism. By the telescopic movement of the telescopic rod 6, the swing rod 7 rotates relative to the column 5 to adjust the orientation of the gripper. In this way, as long as the telescopic movement of the telescopic rod 6 realizes the rotation of the gripper, the structure is simple and the control is convenient. One column 5 serves as the common side of two triangular mechanisms, thus simplifying the equipment structure. By moving the column 5 left and right, the left and right movement of the two grippers is realized.

[0029] The swing rod 7 is a bent rod with a bent portion 701 at the end, and the gripper is fixed on the bent portion 701 of the swing rod 7.

[0030] The technical effects of adopting the above design are as follows: The gripper is fixed on the bent portion 701 of the swing rod 7, which does not affect the rotation of the swing rod 7, and is also conducive to the disassembly, replacement and other operations of the gripper, so as to adopt different grippers according to needs.

[0031] The column 5 is slidably arranged on the guide rail 1, and the column 5 is controlled by a telescopic cylinder 8 to move along the guide rail 1. The telescopic cylinder 8 is a cylinder.

[0032] The technical effect of adopting the above design is as follows: the telescopic cylinder 8 is used to control the sliding of the column 5 on the guide rail 1, and by moving the column 5 left and right, the left and right movement of the two jaws can be realized, with a simple structure and convenient control.

[0033] It further includes a magazine 9 for placing the sheet 4 at both ends of the guide rail 1. The lower end of the magazine 9 has a discharge port 901. The sheets 4 are stacked vertically in the magazine 9. A lifting suction cup 10 corresponding to the discharge port 901 is arranged below the magazine 9. The lifting suction cup 10 is controlled by a lifting cylinder 11 to move up and down.

[0034] The technical effect of adopting the above design is as follows: the lifting suction cup 10 rises to contact the sheet 4 at the discharge port 901, and then the lifting suction cup 10 generates negative pressure to adsorb the sheet 4. Then, the lifting cylinder 11 causes the lifting suction cup 10 to descend to pull out the adsorbed sheet 4 from the discharge port 901. Since the sheet 4 is flexible, that is, it has a certain deformation ability, and it is a sheet, it can be pulled out from the discharge port 901 of the sheet 4.

[0035] A plurality of guide wheels 902 for supporting the edge of the sheet 4 are arranged at the edge of the discharge port 901, so that the sheet 4 is supported by the guide wheels 902.

[0036] The technical effect of adopting the above design is as follows: since the sheet 4 is supported by the guide wheels 902, when the suction cup pulls the sheet 4 downward, the friction between the guide wheels 902 and the sheet 4 is rolling friction, thereby reducing the resistance between the guide wheels 902 and the sheet 4, facilitating the smooth pulling out of the sheet 4, and avoiding the sheet 4 from being damaged by pulling.

[0037] The number of the lifting suction cups 10 is multiple, and the lifting suction cups 10 are arranged corresponding to different corners of the sheet 4. In this embodiment, the sheet 4 is rectangular, so four lifting suction cups 10 are arranged corresponding to the four rectangular corners.

[0038] The technical effect of adopting the above design is as follows: the suction cups are arranged corresponding to different corners of the sheet 4, so that the position of the suction force of the suction cup is closer to the edge of the sheet 4, resulting in a smaller area where stress exists on the sheet 4, avoiding the sheet 4 from being damaged by pulling, and at the same time facilitating the rapid pulling out of the sheet 4.

[0039] The lifting suction cup 10 is provided with a pressure sensor.

[0040] The technical effects of the above design are as follows: The pressure sensor is used to detect the magnitude of the negative pressure generated by the suction cup. When the lifting suction cup 10 sucks the sheet 4, negative pressure will be generated. If the pressure sensor does not sense negative pressure, it means there is no sheet 4 in the storage bin 9. If negative pressure is sensed, it indicates that the sheet 4 has been sucked.

[0041] A specification dispenser with a sheet 4 conveying device. A conveying track 12 for conveying the packaging box 14 and a level sensor for detecting whether the packaging box 14 is located below the clamping jaw are provided below the guide rail 1. The level sensor is an optoelectronic level sensor.

[0042] The technical effects of the above design are as follows: During production, the packaging box 14 passes sequentially below the guide rail 1 along the conveying track 12. When the level sensor detects that the packaging box 14 is located below the clamping jaw, the clamping jaw opens, and thus the specifications clamped by the clamping jaw are placed into the lower packaging box 14.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0044] Although more terms are used in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model. For the execution order of actions, steps, etc. in the devices and methods shown in the specification and drawings, as long as there is no specific order limitation, and as long as the output of the previous process is not used in the subsequent process, they can be implemented in any order. The similar sequential terms (such as "first", "then", "second", "again", "then", etc.) used for convenience of description do not mean that implementation must be in such an order.

[0045] Those of ordinary skill in the art should understand that all directional references (such as above, below, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are descriptively used in the drawings to assist the reader's understanding and do not represent (such as for position, orientation, or use, etc.) a limitation on the scope of the present utility model defined by the appended claims. They are only for the convenience of describing this application and simplifying the description. Without contrary description, these directional terms do not indicate and imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. The directional terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0046] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0047] In addition, some ambiguous terms (e.g., substantially, certain, generally, etc.) may refer to a slight imprecision or slight deviation in conditions, quantities, values, dimensions, etc., some of which are within the manufacturing tolerances or variances. It should be noted that the use of terms such as "first", "second", etc. to define components is only for the convenience of differentiating the corresponding components. Without further statement, the above terms have no special meaning and thus should not be construed as limiting the scope of protection of this application.
