The fifth conveying device is used to convey the materials conveyed from the transfer structure and the materials conveyed from the fourth conveying device in a set state.

[0017] Furthermore, a first detection device, a second detection device and a control device are also provided on the machine body. The first detection device is used to detect whether there is material passing through the fourth conveying device, and the second detection device is used to detect whether there is material passing through the fifth conveying device.

[0018] Furthermore, at least two of the fourth conveying devices are arranged from back to front on the machine body, and each of the fourth conveying devices is provided with a first detection device. The first detection devices are used one by one to detect whether there is material passing through the fourth conveying devices.

Specific embodiments

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] See also Figure 1-Figure 5 , shows a material finishing machine according to a preferred embodiment of the present invention, including a body 10, on which are provided:

[0041] The material conveying device comprises a material conveying device for conveying a material in a first direction (i.e. Figure 1 A first conveying device 20 for conveying materials from back to front (in the A direction) and a ... Figure 1 A second conveying device 30 for conveying materials conveyed from the front end of the first conveying device 20 from back to front (in the B direction), the first conveying device 20 and the second conveying device 30 are arranged from top to bottom, and the first direction and the second direction are opposite;

[0042] The material turning device includes: a third conveying device 60, which is located in front of the second conveying device 30 and is used to convey the material conveyed from the second conveying device 30 from back to front; a visual detection device 70, which is used to detect whether the material passing through the third conveying device 60 is in a set state; a fourth conveying device 80, which is located in front of the third conveying device 60 and is used to convey the material conveyed from the third conveying device 60 and in a set state from back to front; the front end of the third conveying device 60 is movably arranged, and the front end of the third conveying device 60 can move to a distance from the rear end of the fourth conveying device 80 and form a material outlet when the visual detection device 70 detects that the material is not in the set state; a transfer structure 100 is provided with a guide surface 101, and the guide surface 101 is used to guide the material conveyed from the material outlet to turn it to make it in a set state and allow the material to be conveyed out in the set state; a fifth conveying device 90, which is used to receive the material conveyed from the transfer structure 100 and convey the material out in a set state.

[0043] The material sorting machine of the present invention makes full use of the space in the height direction of the machine body 10, avoids increasing the length dimension of the machine body 10, and has a more compact overall structure, occupies less space, and is more convenient for storage, transportation and installation. After the material is transported to the third conveying device 60, if the material is in a set state, the material is transported out through the third conveying device 60 and the fourth conveying device 80 in sequence. If the visual detection device 70 detects that the material is not in the set state, the front end of the third conveying device 60 is driven to move with the fourth conveying device 80. The rear end of the fourth conveying device 80 is separated by a distance and forms a material outlet. Then, under the action of inertia and its own gravity, the material makes a parabolic motion or other motion from the material outlet toward the transfer structure 100. When the material moves to the guide surface 101, it is blocked by the guide surface 101. The guide surface 101 is used to guide and flip the material to a set state. Finally, the material is received by the fifth conveying device 90 and conveyed out in a set state. This structure can realize material flipping, so that the material can always be conveyed out in a set state, which is convenient for the efficient operation of the next process. The structure is simple and practical, easy to manufacture and assemble, low cost, and high working reliability and operation stability, which is more convenient for promotion and application.

[0044] Specifically in this embodiment, the material is provided with a set mark (the set mark can be specifically the end of the material with an easy-tear opening or the end of the material with a hanging hole or the front end when in use), and the material passes through each conveying device in sequence with the set mark facing forward or backward. After the material is conveyed to the third conveying device 60, if the set mark of the material is in the set state facing forward, the material is conveyed out through the third conveying device 60 and the fourth conveying device 80 in sequence. If the visual detection device 70 detects that the set mark of the material is not in the set state facing forward (that is, the set mark of the material is facing backward at this time), the front end of the third conveying device 60 is driven to move and is connected with the fourth conveying device 80. The rear end of the conveying device 80 is separated by a distance and forms a material outlet. Then, under the action of inertia and its own gravity, the material makes a parabolic motion or other motion from the material outlet toward the transfer structure 100. When the material moves to the guide surface 101, it is blocked by the guide surface 101. The guide surface 101 is used to guide and flip the material to make its set target in a set state facing forward. Then, the material slides down to the fifth conveying device with the set target facing backward. Finally, the material is received by the fifth conveying device 90 and conveyed out with the set target facing forward, ensuring that the material can always be conveyed out with the set target facing forward.

[0045] As a preferred embodiment of the material finishing machine of the present invention, it also has the following additional technical features:

[0046] In this embodiment, a connecting structure 50 is also provided on the body 10, and the connecting structure 50 is located between the front end of the first conveying device 20 and the rear end of the second conveying device 30. The connecting structure 50 is provided with an arc track 51, and the arc track 51 is used for the material to slide down from the front end of the first conveying device 20 to the rear end of the second conveying device 30. This structure allows the material to slide down smoothly and without damage along the trajectory direction of the arc track 51 to the second conveying device 30 by inertia and its own gravity. There is basically no collision and impact during the material conveying process, which avoids material damage, and the material conveying quality is high. The structure is simple and practical, and it is more convenient to promote and apply. In other embodiments, the first conveying device 20 and the second conveying device 30 are arranged as close as possible, and the rear end of the second conveying device 30 protrudes from the front end of the first conveying device 20, so that the material conveyed from the front end of the first conveying device 20 directly falls onto the second conveying device 30. This structure can also realize the conveying of materials through the first conveying device 20 and the second conveying device 30 in sequence, and can reduce the collision and impact on the materials, effectively avoiding material damage.

[0047] In this embodiment, the connecting structure 50 is an arc-shaped slide, which is simple, practical, compact, easy to manufacture and assemble, and has excellent reliability.

[0048] In this embodiment, the second conveying device 30 is a roller conveying device, and the machine body 10 is also provided with: a sixth conveying device 40, which is a belt conveying device or a chain conveying device, located between the connecting structure 50 and the rear end of the second conveying device 30, and is used to convey the material conveyed from the connecting structure 50 to the rear end of the second conveying device 30. Because the sixth conveying device 40 is a belt conveying device or a chain plate conveying device with no gaps or basically no gaps on the working surface, the material conveyed by the self-connecting structure 50 is first conveyed to the sixth conveying device 40, and then conveyed to the second conveying device 30 through the sixth conveying device 40, thereby avoiding the problem that the material conveyed by the self-connecting structure 50 is directly conveyed to the second conveying device 30 which is a roller conveying device, causing the material to be stuck in the gap between the two adjacent conveying rollers on the second conveying device 30, so that the material conveying is smoother and the conveying efficiency is higher. At the same time, because the second conveying device 30 is a roller conveying device, there is a distance between the two adjacent rollers in the roller conveying device. During the material conveying process, it can play a certain dispersing role on the stacked materials, avoid material stacking, and convey the materials to the third conveying device 60 one by one in an orderly manner, which is conducive to improving the subsequent detection accuracy and higher working reliability.

[0049] In this embodiment, the second conveying device 30 and the sixth conveying device 40 are parallel to the first conveying device 20, and the rear end of the sixth conveying device 40 is aligned with the front end of the first conveying device 20. This structure is more compact, with a smaller overall volume, and is more convenient for storage, transportation and installation. At the same time, it makes material transportation smoother and smoother, which is conducive to further improving the transportation efficiency.

[0050] In this embodiment, the rear end (i.e., the inlet end) of the first conveying device 20 and the front end (i.e., the outlet end) of the material turning device are both located on the same side of the machine body 10. This structure is more compact, occupies less space, and is more convenient to install.

[0051] In this embodiment, an inclined plane inclined inward from bottom to top is provided on the machine body 10, and the first conveying device 20, the second conveying device 30 and the sixth conveying device 40 are all vertically arranged on the inclined plane, that is, the inner side of the first conveying device 20, the second conveying device 30 and the sixth conveying device 40 connected to the machine body 10 is lower than the outer side away from the machine body 10, so that the material can be conveyed along the side close to the machine body 10 to prevent the material from falling, without the need to set up an additional baffle, the structure is simple and practical, more convenient to manufacture and assemble, and reduces the cost.

[0052] In this embodiment, the guide surface 101 is an arcuate surface for guiding the material delivered from the material outlet to flip to a set state and allow the material to slide down to the fifth conveying device 90. It can not only guide the material to flip, but also allow the material to slide down smoothly to avoid material jamming, thereby improving the material conveying efficiency. In other embodiments, the guide surface 101 can be an inclined surface, which can also guide the material to flip to a set state and allow the material to slide down to the fifth conveying device 90.

[0053] In this embodiment, the transfer structure 100 is specifically a curved slide with a curved surface. This structure is simple and practical, occupies a small space, is easy to manufacture and assemble, and has excellent working reliability.

[0054] In this embodiment, the third conveying device 60 is Figure 6-Figure 7 The retractable belt conveyor device shown in FIG. 1 , when the visual detection device 70 detects that the material is not in the set state, the front end of the retractable belt conveyor device retracts in the direction away from the rear end of the fourth conveyor device 80 and is separated from the fourth conveyor device 80 by a distance and forms a material outlet, so that the material can be conveyed to the transfer structure 100 through the material outlet. After the set time, the front end of the retractable belt conveyor device extends in the direction close to the fourth conveyor device 80 and resets to communicate with the fourth conveyor device 80, so that the material can be conveyed out through the fourth conveyor device 80 in the set state. In other embodiments, the third conveyor device 60 is as follows Figure 8-Figure 9The swingable belt conveyor device shown in the figure, when the visual detection device 70 detects that the material is not in the set state, the front end of the swingable belt conveyor device is driven to swing downward and is separated from the fourth conveying device 80 by a distance and forms a material outlet, so that the material can be conveyed to the transfer structure 100 through the material outlet. After the set time, the front end of the swingable belt conveyor device is driven to swing upward and reset to be connected with the rear end of the fourth conveying device 80, so that the material can be conveyed out through the fourth conveying device 80 in the set state.

[0055] See also Figure 6-Figure 7 In the present embodiment, the retractable belt conveyor device comprises a frame 61, a retractable conveyor belt device 62 and a retractable driving device; the rear end of the retractable conveyor belt device 62 is arranged on the frame 61; the retractable driving device is arranged on the frame 61, and the retractable driving device comprises a servo motor 63 and a transmission device, one end of the transmission device is connected to the servo motor 63, and the other end of the transmission device is connected to the front end of the retractable conveyor belt device 62. Since the power source of the retractable driving device is the servo motor 63, the stroke and speed of the retractable driving device can be adjusted, so that the distance between the front end of the retractable conveyor belt device 62 and the rear end of the fourth conveying device 80 can be adjusted, which can be suitable for conveying materials of different sizes, and is more flexible and convenient.

[0056] In this embodiment, the transmission device includes a belt transmission device 64, a slide rail structure 65 and a connecting frame 66. The belt transmission device 64 is rotatably arranged on the frame 61. The input end of the belt transmission device 64 is transmission-connected to the servo motor 63. The slide rail of the slide rail structure 65 is fixed on the frame 61. The slider of the slide rail structure 65 is fixed to the transmission belt of the belt transmission device 64. The connecting frame 66 is arranged on the slider. The front end of the retractable conveyor belt device 62 is connected to the connecting frame 66. When the servo motor 63 is started, the belt transmission device 64 rotates to drive the slider to slide, thereby driving the front end of the retractable conveyor belt device 62 to perform a telescopic movement.

[0057] like Figure 8-Figure 9 The swingable belt conveyor device includes a base, a swingable conveyor belt device 67 and a swinging driving device 68. The rear end of the swingable conveyor belt device 67 is arranged on the base, and the swinging driving device 68 is arranged on the base. The swinging driving device 68 is transmission-connected with the front end of the swingable conveyor belt device 67 to drive the front end of the swingable conveyor belt device 67 to swing up and down.

[0058] In this embodiment, baffles are provided on opposite sides of a working surface of the third conveying device 60 to limit the materials within the field of view of the visual inspection device 70, thereby avoiding missed inspections and improving the inspection accuracy.

[0059] In this embodiment, the fifth conveying device 90 is located below the transfer structure 100, the rear end of the fifth conveying device 90 extends to behind the transfer structure 100, and the front end of the fifth conveying device 90 extends to before the front end of the fourth conveying device 80. A gap for material to pass through is formed between the fifth conveying device 90 and the front end of the fourth conveying device 80, so that the material conveyed from the transfer structure 100 can be conveyed out through the fifth conveying device 90. The fifth conveying device 90 is used to convey the material conveyed from the transfer structure 100 and the material conveyed from the fourth conveying device 80 in a set state. This structure allows the materials conveyed from the transfer structure 100 and the fourth conveying device 80 to be collected and conveyed out through the same conveying outlet, which is a two-line-in-one setting, which can make the structure more compact and simple, and lower the cost.

[0060] In this embodiment, a first detection device 110, a second detection device 120 and a control device are also provided on the body 10. The first detection device 110 is used to detect whether there is material passing through the fourth conveying device 80, and the second detection device 120 is used to detect whether there is material passing through the fifth conveying device 90. The control device is used to control the start of the first detection device 110 according to the material passing information fed back by the second detection device 120, and control the shutdown of the fourth conveying device 80 according to the material passing information fed back by the first detection device 110. When materials pass through the fourth conveying device 80 and no materials pass through the fifth conveying device 90, the fourth conveying device 80 and the fifth conveying device 90 both operate normally, so that the materials are sequentially conveyed through the fourth conveying device 80 and the fifth conveying device 90; when materials pass through the fifth conveying device 90, the second detection device 120 is triggered and sends a control instruction to the control device, and the control device controls the first detection device 110 to start, and the first detection device 110 detects whether there is material passing through the fourth conveying device 80. If it is detected that there is material passing through the fourth conveying device 80, a control instruction is sent to the control device, and the control device controls the fourth conveying device 80 to shut down, so that the fourth conveying device 80 suspends conveying materials. After the materials on the fifth conveying device 90 are conveyed out, the control device controls the fourth conveying device 80 to start and convey the materials out, so as to avoid the materials conveyed from the fourth conveying device 80 and the materials conveyed from the rear end of the fifth conveying device 90 simultaneously reaching the connection between the fifth conveying device 90 and the front end of the fourth conveying device 80, thereby causing the materials to be stacked together, so that the materials can be conveyed one by one in an orderly manner, which is conducive to improving efficiency.

[0061] The first detection device 110 and the second detection device 120 can both be photoelectric sensors or cameras, and those skilled in the art can flexibly select them according to needs, and are not limited thereto.

[0062] In this embodiment, three fourth conveying devices 80 are arranged from back to front on the machine body 10, and each fourth conveying device 80 is provided with a first detection device 110. Each first detection device 110 is used to detect whether there is material passing through each fourth conveying device 80. After the second detection device 120 detects that there is material passing through the fifth conveying device 90, the control device controls each first detection device 110 to start in sequence from front to back. After the second detection device 120 detects that there is material passing through the fifth conveying device 90, the control device controls the three first detection devices 110 to start in sequence from front to back. The control device shuts down each fourth conveying device 80 in sequence according to the control instructions of each first detection device 110. This structure can avoid the stacking of materials on the fourth conveying device 80 caused by the subsequent continuous incoming materials when the fourth conveying device 80 located at the front is shut down, and the working reliability is higher, which can further improve the material conveying efficiency, and at the same time, the cost can be controlled at a low level. In other embodiments, the fourth conveying device 80 can be provided with one, two, or more than four, and those skilled in the art can flexibly select according to their needs, and are not limited to this.

[0063] More specifically, the activation and detection sequence of each first detection device 110 is as follows:

[0064] After the second detection device 120 detects that material has passed through the fifth conveying device 90, the control device first controls the first detection device 110 located at the front to start, and the first detection device 110 located at the front detects whether material has passed through the fourth conveying device 80 located at the front. If it is detected that material has passed through the fourth conveying device 80, a control instruction is sent to the control device, and the control device controls the fourth conveying device 80 to be shut down;

[0065] After the first detection device 110 at the front has finished detecting, the control device controls the first detection device 110 in the middle to start, and the first detection device 110 in the middle detects whether there is material passing through the fourth conveying device 80 in the middle. If there is material passing through, the control device controls the corresponding fourth conveying device 80 to shut down;

[0066] After the first detection device 110 located in the middle completes the detection, the control device controls the first detection device 110 located at the rear to start, and the first detection device 110 located at the rear detects whether there is material passing through the fourth conveying device 80 located at the rear. If material passes through, the control device controls the corresponding fourth conveying device 80 to shut down, so that each fourth conveying device 80 with material passing through pauses in conveying the material. After the material on the fifth conveying device 90 is conveyed out (that is, after the set time is reached), the control device controls each fourth conveying device 80 to start and convey the material out in sequence, which can avoid material stacking and ensure efficient material conveying.

[0067] In this embodiment, the fifth conveying device 90 includes a first section 91 located below the fourth conveying device 80 and arranged obliquely, and a second section 92 located in front of the front end of the fourth conveying device 80 and arranged horizontally. The first section 91 is provided with a material baffle plate 94 located behind the transfer structure 100. The material baffle plate 94 is used to block the material conveyed from the transfer structure 100 to prevent the material from sliding down, so that the material can be smoothly conveyed out through the fifth conveying device 90.

[0068] A connecting plate 93 is provided on the first section 91. The connecting plate 93 is close to the front end of the fourth conveying device 80 and is inclined toward the connection between the first section 91 and the second section 92. A gap is formed between the connecting plate 93 and the first section 91. The connecting plate 93 is used to transport the material transported from the fourth conveying device 80 to the fifth conveying device 90. In this way, the material transported from the fourth conveying device 80 can be transported to the front end of the fifth conveying device 90 more smoothly.

[0069] In this embodiment, the fourth conveying device 80 and the fifth conveying device 90 can both be belt conveying devices, chain plate conveying devices, or roller conveying devices, and those skilled in the art can flexibly select them according to needs, and are not limited thereto.

[0070] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
