Description

Technical Field

[0001] The present invention relates to the technical field of lifting transfer machines, and in particular, to a lifting transfer machine and a method for lifting and transferring plates. Background Art

[0002] In existing conveyor lines, it is often necessary to transport workpieces to different workstations for processing. Due to the different functions of different workstations, there will be a certain height difference between different workstations. Therefore, during the transportation of workpieces, equipment is required to move the workpieces to workstations at different heights. In some conveyor lines, swinging is often used for transportation, but this transportation method has certain technical defects, such as limited transportation capacity, high risk of workpiece damage, low transportation efficiency, and insufficient positioning accuracy.

[0003] To solve the problem of difficult docking of workpieces between different height lines during workpiece transportation, some lifting transfer mechanisms with lifting functions have emerged. For example, the patent application with the Chinese patent publication number CN221295262U discloses a lifting type automatic feeding device for plates. By setting a lifting control component and a lifting frame, the plates can be lifted. Although the simple lifting function can be achieved, it is difficult to quickly connect two different lines, and the working efficiency is not high.

[0004] To solve the efficiency problem of the lifting mechanism, the patent application with the Chinese patent publication number CN114030871A discloses a lifting transfer mechanism. The goods grabbing unit grabs the goods, and the lifting drive unit drives the lifting seat to rise. When the goods rise and move to align with the position corresponding to the downstream process, the goods are placed at the downstream process through the goods grabbing unit. Although this method can more efficiently achieve the lifting function, it requires the use of a mechanism with a grabbing function, which is difficult to apply to large-scale plate conveyor lines, has poor adaptability, and there is still a large room for improvement in the transportation accuracy.

[0005] Therefore, how to efficiently and accurately transport plates to conveyor lines at different heights is a technical problem that those skilled in the art need to solve urgently. Summary of the Invention

[0006] The first object of the present invention is to provide a lifting transfer machine that can efficiently and accurately transport plates to conveyor lines at different heights.

[0007] The second object of the present invention is to provide a method for lifting and transferring plates. By using the above-mentioned lifting transfer machine, plates can be efficiently and accurately transported to conveyor lines at different heights.

[0008] To achieve the above first object, the present invention provides the following technical solutions: Provide a lifting transfer machine, including: Transfer device, the transfer device includes a transfer rack, transfer rollers, a transfer conveyor belt, transfer baffles, and a belt lifting cylinder. The transfer rollers, the transfer conveyor belt, the transfer baffles, and the belt lifting cylinder are all arranged on the transfer rack.

[0009] Through the above solution, when conveying between conveyor lines at different heights, the conveyor line of the previous process conveys the sheet to one side of the transfer device. The part of the transfer conveyor belt that protrudes from the transfer rollers is used to receive the conveyed sheet, playing a connecting role, enabling the sheet to be conveyed to above the transfer rollers more smoothly and quickly, effectively improving the transfer efficiency. Then the transfer conveyor belt continues to convey the sheet until the edge of the sheet abuts against the transfer baffle, ensuring that the sheet completely leaves the conveyor line of the previous process and completely enters above the transfer rollers. The belt lifting cylinder drives the transfer conveyor belt to descend until the conveying plane of the transfer conveyor belt is lower than the conveying plane of the transfer rollers. The sheet is received by the transfer rollers. The lifting device drives the transfer rack to move so that the conveying plane of the transfer rollers is at the same horizontal plane as the conveying plane of the conveyor line of the next process. The transfer rollers convey the sheet to the conveyor line of the next process. The whole process is very efficient, and the sheet can be quickly transferred between conveyor lines at different heights. Moreover, transfer baffles are used to ensure that the sheet can completely enter the area of the transfer rollers, enabling the sheet to fall into the same area each time, ensuring accurate entry into the conveyor line of the next process, and the conveying accuracy is higher.

[0010] Optionally, the transfer device further includes a belt support frame. The belt lifting cylinder is connected to the belt support frame, and the transfer conveyor belt is arranged on the belt support frame.

One end of the universal coupling is connected to the belt transmission shaft, and the other end of the universal coupling is connected to the belt motor.

[0012] Optionally, the transfer device further includes a roller motor, a roller transmission shaft, and an endless belt. One end of the endless belt is connected to the transfer rollers, and the other end of the endless belt is connected to the roller transmission shaft. The roller motor is connected to the roller transmission shaft.

[0013] Optionally, the lifting device includes a lifting base, a lifting motor, a lifting transmission member, and a lifting support frame. The lifting support frame is movably connected to the lifting base. The lifting motor is connected to the lifting support frame through the lifting transmission member, and the lifting support frame is connected to the transfer rack.

[0014] Optionally, the lifting transmission member includes a lifting chain, a lifting sprocket, a lifting driving shaft, and a lifting driven shaft. The lifting driving shaft and the lifting driven shaft are both arranged on the lifting base. The lifting driving shaft and the lifting driven shaft are both provided with the lifting sprocket. The lifting chain is wound around the lifting sprocket, and the lifting support frame is connected to the lifting chain.

[0015] Optionally, the lifting device further includes a counterweight and a counterweight guide post. The counterweight is connected to the lifting chain. The counterweight and the lifting support frame are respectively located on both sides of the lifting chain. The counterweight guide post is arranged on the lifting base, and the counterweight is slidably connected to the counterweight guide post.

[0016] Optionally, the lifting device further includes a lifting guide rail and a lifting slider. The lifting guide rail is arranged on the lifting base. The lifting slider is slidably connected to the lifting guide rail, and the lifting support frame is connected to the lifting slider.

[0017] Optionally, the lifting device further includes a lifting limit block. The lifting limit block is arranged on the lifting base and is arranged on the lower side of the lifting support frame.

[0018] To achieve the above second object, the present invention provides the following technical solutions: Provide a method for lifting and transferring a sheet material, using the above-mentioned lifting and transfer machine, including the following steps: S1. The conveyor line of the previous process conveys the sheet material to one side of the transfer device; S2. The part of the transfer conveyor belt protruding from the transfer roller receives the sheet material, and the transfer conveyor belt continues to convey the sheet material until the edge of the sheet material abuts against the transfer baffle; S3. The belt lifting cylinder drives the transfer conveyor belt to descend until the sheet material is received by the transfer roller; S4. The lifting device drives the transfer rack to move so that the conveying plane of the transfer roller and the conveying plane of the conveyor line of the next process are on the same horizontal plane; S5. The transfer roller conveys the sheet material to the conveyor line of the next process.

[0019] Compared with the prior art, the solution of the present invention has the following advantages: 1. In the lifting and transfer machine of the present invention, when transporting between conveyor lines at different heights, the conveyor line of the previous process transports the sheet to one side of the transfer device. The part of the transfer conveyor belt protruding from the transfer roller is used to receive the transported sheet, playing a connecting role, enabling the sheet to be transported to above the transfer roller more smoothly and quickly, effectively improving the transfer efficiency. Then, the transfer conveyor belt continues to transport the sheet until the transport plane of the transfer conveyor belt is lower than the transport plane of the transfer roller, and the edge of the sheet abuts against the transfer baffle, ensuring that the sheet completely leaves the conveyor line of the previous process and completely enters above the transfer roller. The belt lifting cylinder drives the transfer conveyor belt to descend until the sheet is received by the transfer roller. The lifting device drives the transfer rack to move, so that the transport plane of the transfer roller is at the same horizontal plane as the transport plane of the conveyor line of the next process. The transfer roller transports the sheet to the conveyor line of the next process. The whole process is very efficient, capable of quickly transferring the sheet between conveyor lines at different heights. Moreover, the transfer baffle is adopted to ensure that the sheet can completely enter the area of the transfer roller, enabling the sheet to fall into the same area each time, ensuring accurate entry into the conveyor line of the next process, and having higher transport accuracy.

Detailed implementation manners

[0024] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0025] As Figures 1 to 7 shown, the present invention provides a lifting transfer machine capable of conveying workpieces. In this embodiment, the conveying of plates is mainly taken as an example for illustration. In some other embodiments, the lifting transfer machine provided by the present invention can also convey workpieces such as boxes and pallets.

[0026] The lifting transfer machine provided by the present invention includes a transfer device 1, a lifting device 2 and a control device. The transfer device 1 includes a transfer frame 101, transfer rollers 102, a transfer conveyor belt 103, a transfer baffle 104 and a belt lifting cylinder 105. The transfer rollers 102, the transfer conveyor belt 103, the transfer baffle 104 and the belt lifting cylinder 105 are all arranged on the transfer frame 101. The transfer conveyor belt 103 conveys workpieces in a first direction. One end of the transfer conveyor belt 103 protrudes from the transfer rollers 102 in the first direction. The transfer baffle 104 is located at the other end of the transfer conveyor belt 103. The belt lifting cylinder 105 is connected to the transfer conveyor belt 103. The lifting device 2 is connected to the transfer frame 101. The control device is electrically connected to the transfer device 1 and the lifting device 2 respectively.

[0027] For the convenience of explanation, in this embodiment, as Figure 1As shown, the first direction is the front-back direction.

[0028] Specifically, before transferring the board, the belt lifting cylinder 105 will drive the transfer conveyor belt 103 to move upward so that the transfer conveyor belt 103 is located above the transfer roller 102. Then the board can pass through the transfer conveyor belt 103 and enter above the transfer roller 102. The rotation axis of the transfer roller 102 extends along the front-back direction. The transfer roller 102 conveys the board along the left-right direction, and the transfer conveyor belt 103 conveys the board along the front-back direction. As Figure 4 shown, the front end of the transfer conveyor belt 103 protrudes from the transfer roller 102, and the transfer baffle 104 is located at the rear end of the transfer conveyor belt 103.

[0029] It should be noted that in this embodiment, the transfer conveyor belt 103 can convey the board from front to back above the transfer roller 102, and the transfer conveyor belt 103 can also convey the board from back to front from above the transfer roller 102 to the conveyor line of other processes. Similarly, the transfer roller 102 can convey the board from left or right from above the transfer roller 102 to the conveyor line of other processes. Therefore, in addition to being able to transfer the board between conveyor lines at different heights, it can also transfer the board between conveyor lines with different conveying directions, realizing a multi-station conveying mode of one input and multiple outputs, with better adaptability, stronger functionality, and multi-purpose use of one machine, which can save the floor space of the conveyor line, improve space utilization rate, and reduce production costs.

[0030] Taking the transfer from a lower conveyor line to a higher conveyor line as an example when the lifting transfer machine provided by the present invention conveys between conveyor lines at different heights, the conveyor line of the previous process conveys the board from front to back to the front side of the transfer device 1. The part of the transfer conveyor belt 103 that protrudes from the transfer roller 102 is used to receive the conveyed board, playing a connecting role to prevent the conveyor line of the previous process from not being able to completely push the board into the transfer device 1. The protruding part of the transfer conveyor belt 103 enables the board to be conveyed more smoothly and quickly above the transfer roller 102, effectively improving the transfer efficiency.

[0031] Further, the transfer conveyor belt 103 continues to convey the sheet until the edge of the sheet abuts against the transfer baffle 104, ensuring that the sheet completely leaves the conveyor line of the previous process and completely enters directly above the transfer roller 102. The belt lifting cylinder 105 drives the transfer conveyor belt 103 to descend until the conveying plane of the transfer conveyor belt 103 is lower than the conveying plane of the transfer roller 102. The sheet is then received by the transfer roller 102. The lifting device 2 drives the transfer rack 101 to move upward so that the conveying plane of the transfer roller 102 and the conveying plane of the conveyor line of the next process are at the same horizontal level. The transfer roller 102 conveys the sheet to the conveyor line of the next process. The whole process is very efficient, capable of quickly transferring the sheet between conveyor lines at different heights. Moreover, the transfer baffle 104 is adopted to ensure that the sheet can completely enter the area of the transfer roller 102, enabling the sheet to fall into the same area each time and ensuring accurate entry into the conveyor line of the next process, with higher conveying accuracy.

[0032] In some embodiments, the control device is an industrial control computer. In some other embodiments, the control device can also be a single-chip microcomputer or other units integrated with control functions.

[0033] In some embodiments, as Figures 2 to 5 shown, the transfer device 1 further includes a belt support frame 106. The belt lifting cylinder 105 is connected to the belt support frame 106, and the transfer conveyor belt 103 is arranged on the belt support frame 106. Specifically, belt support frames 106 and belt lifting cylinders 105 are provided on both the front and rear sides of the transfer conveyor belt 103. The front end of the transfer conveyor belt 103 is connected to the front belt support frame 106, and the rear end of the transfer conveyor belt 103 is connected to the rear belt support frame 106. The belt lifting cylinder 105 drives the belt support frame 106 to move up and down, thereby driving the transfer conveyor belt 103 to move up and down, enabling the transfer conveyor belt 103 to move above the transfer roller 102 to connect with the sheet and also move below the transfer roller 102 to leave the sheet, so that the sheet can be received by the transfer roller 102. Through such a setting, the transfer conveyor belt 103 can be driven to move up and down more quickly, effectively improving the efficiency of sheet transfer.

[0034] In some embodiments, as Figures 2 to 5As shown, the transfer device 1 further includes a belt motor 107, a belt transmission shaft 108, and a universal coupling 109. The number of transfer conveyor belts 103 is multiple. The multiple transfer conveyor belts 103 are all connected to the belt transmission shaft 108. One end of the universal coupling 109 is connected to the belt transmission shaft 108, and the other end of the universal coupling 109 is connected to the belt motor 107. Specifically, the multiple transfer conveyor belts 103 are interspersed between the transfer rollers 102, which can effectively save the occupied space of the transfer device 1 and have a higher space utilization rate. By setting the universal coupling 109, it is ensured that even when the transfer conveyor belt 103 moves up and down, the power of the belt motor 107 can still be transmitted to the belt transmission shaft 108, and the transfer conveyor belt 103 can still be driven to convey the plates, effectively ensuring the conveying efficiency.

[0035] In some embodiments, as Figures 3 to 5 shown, the transfer device 1 further includes a belt tensioning frame 110. The transfer conveyor belt 103 is a synchronous belt. The transfer conveyor belt 103 is arranged on the belt tensioning frame 110. Synchronous pulleys are provided on the belt tensioning frame 110. The belt transmission shaft 108 transmits power to the transfer conveyor belt 103 through the synchronous pulleys, and the working efficiency is higher.

[0036] In some embodiments, as Figure 4 shown, the transfer device 1 further includes a roller motor 111, a roller transmission shaft 112, and an endless belt 113. One end of the endless belt 113 is connected to the transfer roller 102, and the other end of the endless belt 113 is connected to the roller transmission shaft 112. The roller motor 111 is connected to the roller transmission shaft 112, which can convey the plates more efficiently.

[0037] In some embodiments, the transfer roller 102 is a rubber-coated roller, which can avoid damaging the plates and also has anti-slip performance, and the conveying efficiency is higher.

[0038] In some embodiments, as Figures 1 to 5 shown, the front end of the transfer conveyor belt 103 is connected to the front belt support frame 106. The front belt support frame 106 is located below the part where the transfer conveyor belt 103 protrudes from the transfer roller 102. The transfer device 1 further includes a first detection unit 114. The first detection unit 114 is arranged on the front belt support frame 106. The first detection unit 114 is electrically connected to the control device. The first detection unit 114 is used to detect whether there are plates on the part where the transfer conveyor belt 103 protrudes from the transfer roller 102. Specifically, when the conveying line of the previous process conveys the plates and the plates start to enter the transfer conveyor belt 103, the plates will trigger the first detection unit 114. The first detection unit 114 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 2, and the lifting device 2 does not work, which can prevent the lifting device 2 from being accidentally triggered and causing the plates to fall, and improve the safety of the entire equipment.

[0039] In addition, arranging the first detection unit 114 on the front belt support frame 106 can save the occupied space of the entire equipment and improve the space utilization rate.

[0040] In some embodiments, the first detection unit 114 is a photoelectric switch, which can more accurately detect whether there is a plate on the portion of the transfer conveyor belt 103 protruding from the transfer roller 102 .

[0041] In some embodiments, Figures 1 to 5 As shown, the transfer device 1 also includes a second detection unit 115, which is arranged above the transfer baffle 104. The second detection unit 115 is electrically connected to the control device. The second detection unit 115 is used to detect whether the plate has abutted against the transfer baffle 104 to ensure that the plate has completely entered above the transfer roller 102. It has a higher degree of intelligence and can prevent the lifting device 2 from being accidentally triggered to cause the plate to fall, thereby improving the safety of the entire equipment.

[0042] In some embodiments, the second detection unit 115 is a distance sensor, which can detect the distance between the plate and the second detection unit 115, thereby confirming whether the plate has abutted against the transfer baffle 104, which is more intelligent.

[0043] It is worth noting that the first detection unit 114 and the second detection unit 115 can work together to improve the safety during lifting and transfer. Specifically, when the conveyor line of the previous process conveys the plate, when the plate begins to enter the transfer conveyor belt 103, the plate will trigger the first detection unit 114, and the first detection unit 114 will transmit the corresponding electrical signal to the control device, and the control device will transmit the corresponding electrical signal to the lifting device 2. When the lifting device 2 does not work and the plate completely enters the top of the transfer roller 102, the first detection unit 114 cannot detect the plate. At this time, if the second detection unit 115 also cannot detect the plate, it means that the plate has not reached the top of the transfer roller 102. Connected to the transfer baffle 104, the lifting device 2 still does not lift until the second detection unit 115 detects the plate. The second detection unit 115 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 2. The lifting device 2 transports the transfer rack 101 to the horizontal plane where the conveyor line of the next process is located. By setting the first detection unit 114 and the second detection unit 115 to be linked, it is possible to better detect whether the plate has entered the top of the transfer roller 102 and abutted against the transfer baffle 104, and then lift and transfer it, which further improves the safety and intelligence of the equipment.

[0044] Further, when the sheet is conveyed to the conveyor line of the next process and the second detection unit 115 detects the sheet, the second detection unit 115 transmits the corresponding electrical signal to the lifting device 2, and the lifting device 2 does not operate. After detecting that the sheet has completely left the transfer conveyor belt 103, the second detection unit 115 transmits the corresponding electrical signal to the lifting device 2. After an interval of time, such as 1 second later, the lifting device 2 operates to convey the transfer rack 101 to the horizontal plane where the conveyor line of the previous process is located, with higher automation and higher safety.

[0045] In some embodiments, as Figures 1 to 5 shown, the lifting transfer machine further includes a blocking device 3. Blocking devices 3 are provided on both the left and right sides of the transfer rack 101. For the convenience of description, the accompanying drawings only show the blocking device 3 on the left side. When the sheet is located on the upper surface of the transfer roller 102, sliding may occur. By providing the blocking device 3, the sheet can be prevented from leaving the transfer roller 102 from both the left and right sides, avoiding the sheet from falling, and further improving the safety of the equipment.

[0046] In some embodiments, as Figure 5 shown, the blocking device 3 includes a blocking cylinder 301 and a blocking plate 302. The blocking cylinder 301 is provided on the transfer rack 101. The blocking cylinder 301 is connected to the blocking plate 302 and drives the blocking plate 302 to move up and down, so as to block or release the sheet, with higher safety.

[0047] Further, the thickness of the blocking plate 302 is 1 cm to 3 cm, such as 2 cm. While ensuring the blocking effect, it will not occupy too much space and avoid affecting the connection with the conveyor line of the next process.

[0048] In some embodiments, as Figure 5 shown, the blocking device 3 further includes a blocking guide rail 303 and a blocking slider 304. The blocking guide rail 303 is provided on the transfer rack 101. The blocking slider 304 is connected to the blocking plate 302, and the blocking slider 304 is slidably connected to the blocking guide rail 303, which can provide a guiding function for the movement of the blocking plate 302 and improve the safety of the equipment.

[0049] In some embodiments, as Figure 6 and Figure 7As shown, the lifting device 2 includes a lifting base 201, a lifting motor 202, a lifting transmission member, and a lifting support frame 203. The lifting support frame 203 is movably connected to the lifting base 201. The lifting motor 202 is connected to the lifting support frame 203 through the lifting transmission member. The lifting support frame 203 is connected to the transfer rack 101. Specifically, the lifting motor 202 transmits power to the lifting transmission member, and the lifting transmission member transmits power to the lifting support frame 203, thereby driving the lifting support frame 203 to move up and down, and further driving the transfer rack 101 to move up and down. The action is rapid and the working efficiency is high.

[0050] In some embodiments, as Figure 6 and Figure 7 shown, the lifting transmission member includes a lifting chain 204, a lifting sprocket 205, a lifting driving shaft 206, and a lifting driven shaft 207. The lifting driving shaft 206 and the lifting driven shaft 207 are both arranged on the lifting base 201. The lifting driving shaft 206 and the lifting driven shaft 207 are both provided with lifting sprockets 205. The lifting chain 204 is wound around the lifting sprockets 205. The lifting support frame 203 is connected to the lifting chain 204. Specifically, the lifting driving shaft 206 is arranged on the upper side of the lifting base 201, the lifting driven shaft 207 is arranged on the lower side of the lifting base 201, the lifting motor 202 is arranged on the upper side of the lifting base 201, the lifting motor 202 transmits power to the lifting driving shaft 206, and the lifting driving shaft 206, the lifting driven shaft 207, and the lifting sprockets 205 cooperate together to drive the lifting chain 204 to move. When the lifting chain 204 moves, it drives the lifting support frame 203 to move up and down, and further drives the transfer rack 101 to move up and down. The whole moving process is more stable and the safety is higher.

[0051] In some embodiments, as Figure 7 shown, the lifting device 2 further includes a counterweight 208 and a counterweight guide post 209. The counterweight 208 is connected to the lifting chain 204. The counterweight 208 and the lifting support frame 203 are respectively located on both sides of the lifting chain 204. The counterweight guide post 209 is arranged on the lifting base 201. The counterweight 208 is slidably connected to the counterweight guide post 209. Specifically, the lifting support frame 203 is located on the front side of the lifting chain 204, and the counterweight 208 is located on the rear side of the lifting chain 204. By setting the counterweight 208, the stability of the lifting support frame 203 when moving up and down can be improved, thereby improving the safety of the whole device.

[0052] In some embodiments, as Figure 6 and Figure 7As shown, the lifting device 2 further includes a lifting guide rail 210 and a lifting slider 211. The lifting guide rail 210 is provided on the lifting base 201. The lifting slider 211 is slidably connected to the lifting guide rail 210. The lifting support frame 203 is connected to the lifting slider 211. Specifically, the lifting guide rail 210 extends in the up and down direction. The lifting slider 211 is fixedly connected to the lifting support frame 203, for example, fixed by bolts. By providing the lifting guide rail 210 and the lifting slider 211, it can play a guiding role in the movement of the lifting support frame 203. While ensuring the safety of the movement of the lifting support frame 203, it can also prevent the lifting support frame 203 from shifting, improve the accuracy of conveying, and enable the lifting support frame 203 to move efficiently and with high precision.

[0053] In some embodiments, as Figure 6 shown, the lifting device 2 further includes a lifting limit block 212. The lifting limit block 212 is provided on the lifting base 201. The lifting limit block 212 is provided on the lower side of the lifting support frame 203. The lifting limit block 212 is fixedly connected to the lifting base 201, for example, fixed by bolts. The lifting limit block 212 can limit the movement range of the lifting support frame 203 and prevent the lifting support frame 203 from detaching from the lifting base 201, with higher safety.

[0054] In some embodiments, a lifting limit block 212 is also provided on the upper side of the lifting support frame 203, which can further limit the movement range of the lifting support frame 203 and prevent the lifting support frame 203 from detaching from the lifting base 201, with higher safety A method for lifting and transferring sheets provided by an embodiment of the present invention uses the above-mentioned lifting and transfer machine, including the following steps: S1. The conveyor line of the previous process conveys the sheets to one side of the transfer device 1; S2. The part of the transfer conveyor belt 103 protruding from the transfer roller 102 receives the sheets, and the transfer conveyor belt 103 continues to convey the sheets until the edge of the sheets abuts against the transfer baffle 104; S3. The belt lifting cylinder 105 drives the transfer conveyor belt 103 to descend until the sheets are received by the transfer roller 102; S4. The lifting device 2 drives the transfer frame 101 to move so that the conveying plane of the transfer roller 102 is at the same horizontal plane as the conveying plane of the conveyor line of the next process; S5. The transfer roller 102 conveys the sheets to the conveyor line of the next process.

[0055] In some embodiments, in step S2, when the transfer conveyor belt 103 receives the sheets, the conveying plane of the transfer conveyor belt 103 is slightly higher than the conveying surface of the transfer roller 102, for example, 1 centimeter to 3 centimeters, and the structural design is more reasonable.

[0056] In some embodiments, in step S3, when the sheet completely enters above the transfer roller 102, the belt lifting cylinder 105 drives the transfer conveyor belt 103 to descend until the sheet is received by the transfer roller 102, avoiding damage to the sheet.

[0057] Further, in step S3, when the conveyor line of the previous process conveys the sheet and the sheet starts to enter the transfer conveyor belt 103, the sheet will trigger the first detection unit 114. The first detection unit 114 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the belt lifting cylinder 105. The belt lifting cylinder 105 maintains the lifted state. When the sheet completely enters above the transfer roller 102, the first detection unit 114 cannot detect the sheet. At this time, if the second detection unit 115 also cannot detect the sheet, it means that the sheet does not abut against the transfer baffle 104, and the belt lifting cylinder 105 still maintains the lifted state until the second detection unit 115 detects the sheet. The second detection unit 115 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the belt lifting cylinder 105. The belt lifting cylinder 105 lowers the transfer conveyor belt 103 until the sheet is received by the transfer roller 102, avoiding damage to the sheet.

[0058] Similarly, in step S4, when the conveyor line of the previous process conveys the sheet and the sheet starts to enter the transfer conveyor belt 103, the sheet will trigger the first detection unit 114. The first detection unit 114 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 2. The lifting device 2 does not operate. When the sheet completely enters above the transfer roller 102, the first detection unit 114 cannot detect the sheet. At this time, if the second detection unit 115 also cannot detect the sheet, it means that the sheet does not abut against the transfer baffle 104, and the lifting device 2 still does not perform lifting until the second detection unit 115 detects the sheet. The second detection unit 115 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 2. The lifting device 2 transports the transfer rack 101 to the horizontal plane where the conveyor line of the next process is located. By setting the first detection unit 114 and the second detection unit 115 to be linked, it is possible to better detect whether the sheet has entered above the transfer roller 102 and abutted against the transfer baffle 104, and then perform lifting and transfer, further improving the safety and intelligence level of the equipment.

[0059] The above are only some embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
