Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a material conveying device. Background Art

[0002] The packaging process of bagged materials mainly includes the steps of material metering - bagging - bagging of bagged materials. In order to improve the packing efficiency, before packing the bagged materials, it is often necessary to adjust the position of the bagged materials so that the bagged materials can be transported to the packing station one by one in an orderly manner with the set target facing forward (for example, the end of the bagged materials with an easy-tear opening or the end with a hanging hole facing forward or the front end of the bagged materials facing forward when in use).

[0003] At present, bagged materials are mainly turned over by a material turning device, which mainly includes a first conveying device, a second conveying device, a transfer structure and the first conveying device. The material is conveyed from the first conveying device. When the material is in a set state, the material is conveyed to the second conveying device and conveyed out through the first conveying device. When the material is not in a set state, the material is conveyed to the transfer structure, and the material output from the first conveying device is blocked by the transfer structure and guided to turn the material to the set state. Then the material is conveyed from the transfer structure to the first conveying device and conveyed out through the first conveying device in a manner of maintaining the set state. However, because the materials of the second conveying device and the transfer structure are both conveyed out through the first conveying device, the problem of material stacking will occur when the materials on the second conveying device and the transfer structure are conveyed to the connection between the first conveying device and the second conveying device at the same time. The materials are stacked together and affect the packing efficiency. Therefore, it is necessary to make structural improvements. Summary of the invention

Specific embodiments

[0042] 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.

[0043] See also Figure 1-Figure 5 , shows a material conveying device of a preferred embodiment of the present invention, including a body 10, on which are arranged: a first conveying device 20, used to convey materials from back to front; a second conveying device 30, located below the first conveying device 20, the front end of the second conveying device 30 extends to the front end of the first conveying device 20, and the second conveying device 30 and the front end of the first conveying device 20 are separated by a distance and form a gap for material to pass through, and are used to convey materials conveyed from the rear end thereof and materials conveyed from the first conveying device 20 from back to front; a first detection device 40, used to detect whether there is material passing on the first conveying device 20; a second detection device 50, used to detect whether there is material passing on the second conveying device 30; a control device, used to control the first detection device 40 to start according to the material passing information fed back by the second detection device 50, and to control the first conveying device 20 to stop according to the material passing information fed back by the first detection device 40.

[0044] In the material conveying device of the present invention, when material passes through the first conveying device 20 and no material passes through the second conveying device 30, the first conveying device 20 and the second conveying device 30 both operate normally, so that the material is conveyed out through the first conveying device 20 and the second conveying device 30 in sequence; when material passes through the second conveying device 30, the second detection device 50 is triggered and sends a control instruction to the control device, and the control device controls the first detection device 40 to start, and the first detection device 40 detects whether there is material passing through the first conveying device 20. If it is detected that there is material passing through the first conveying device 20, a control instruction is sent to the control device, and the control device controls the first detection device 40 to start. The conveying device 20 is shut down, so that the first conveying device 20 stops conveying materials. After the materials on the second conveying device 30 are conveyed out, the control device controls the first conveying device 20 to start and convey the materials out, so as to avoid the materials conveyed from the first conveying device 20 and the materials conveyed from the rear end of the second conveying device 30 arriving at the connection between the second conveying device 30 and the front end of the first conveying device 20 at the same time, thereby causing the materials to be stacked together, so that the materials can be conveyed one by one in an orderly manner, which is beneficial to improving efficiency. In addition, because the first conveying device 20 and the second conveying device 30 share the same conveying outlet, that is, the two-line-in-one setting, the structure is more compact and the cost is lower.

[0045] The first detection device 40 and the second detection device 50 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.

[0046] As a preferred embodiment of the material conveying device of the present invention, it may also have the following additional technical features:

[0047] In this embodiment, the machine body 10 is provided with three first conveying devices 20 arranged in sequence from back to front, and each first conveying device 20 is provided with a first detection device 40, and each first detection device 40 is used to detect whether there is material passing through each first conveying device 20. After the second detection device 50 detects that there is material passing through the second conveying device 30, the control device controls the three first detection devices 40 to start in sequence from front to back, and the control device shuts down each first conveying device 20 in sequence according to the control instructions of each first detection device 40. This structure can avoid the stacking of materials on the first conveying device 20 caused by the subsequent continuous incoming materials when the first conveying device 20 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 first conveying device 20 can be provided with one, two, or more than four, and those skilled in the art can flexibly select according to needs, and are not limited to this.

[0048] See also Figure 2 In this embodiment, the second conveying device 30 includes a first section 31 located below the first conveying device 20 and arranged obliquely, and a second section 32 located in front of the front end of the first conveying device 20 and arranged horizontally. The second section 32 is parallel to the first conveying device 20. In this way, the structure is more compact and the installation space is saved. At the same time, the material conveyed from the first conveying device 20 can be conveyed to the front end of the second conveying device 30 more smoothly and gently.

[0049] In this embodiment, the front end of the first conveying device 20 is located behind the connection between the first section 31 and the second section 32. A connecting plate 33 is provided on the first section 31. The connecting plate 33 is close to the front end of the first conveying device 20 and is inclined to the connection between the first section 31 and the second section 32. A gap is formed between the connecting plate 33 and the first section 31. The connecting plate 33 is used to transport the material transported from the first conveying device 20 to the second section 32. In this way, the material transported from the first conveying device 20 can be transported to the front end of the second conveying device 30 more smoothly.

[0050] In this embodiment, the body 10 is further provided with: a third conveying device 60, which is located behind the first conveying device 20 and is connected to the first conveying device 20, and is used to convey materials from back to front; a visual detection device 70, which is located above the third conveying device 60, and is used to detect whether the material passing through the third conveying device 60 is in a set state; 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 first conveying device 20 and form a material outlet when the visual detection device 70 detects that the material is not in the set state; a switching structure 80, which is located below the first conveying device 20 and is provided with a guide surface 81, and the guide surface 81 is used to guide the material conveyed from the material outlet to flip to the set state and provide the material for conveying to the second conveying device 30; the second conveying device 30 is used to convey the material conveyed from the switching structure 80 and the material conveyed from the first conveying device 20 in a set state.

[0051] When the material is in the set state, the material is conveyed out through the third conveying device 60 and the first conveying device 20 in sequence. When the visual inspection 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 and is separated from the rear end of the first conveying device 20 by a distance to form 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 80. When the material moves to the guide surface 81, it is blocked by the guide surface 81. The guide surface 81 is used to guide and flip the material to make it in the set state. Finally, the material is taken over by the second conveying device 30 and conveyed out in the set state. This structure can realize the material flipping, so that the material can always be conveyed out in the set state, which is convenient for the efficient operation of the next process. The structure is simple and practical, convenient to manufacture and assemble, low cost, and has high working reliability and operation stability, which is more convenient for promotion and application.

[0052] Specifically in this embodiment, the material is provided with a setting mark (the setting mark can be 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 the third conveying device 60 in sequence with the setting mark facing forward or backward. If the setting mark of the material is in the setting state facing forward, the material is conveyed out through the third conveying device 60 and the first conveying device 20 in sequence. If the visual detection device 70 detects that the setting mark of the material is not in the setting state facing forward (that is, the setting 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 first conveying device 2 0 is separated from the rear end by a distance and forms a material outlet. Then, the material makes a parabolic motion or other motion from the material outlet toward the transfer structure 80 under the action of inertia and its own gravity. When the material moves to the guide surface 81, it is blocked by the guide surface 81. The guide surface 81 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 second conveying device 30 with the set target facing backward. Finally, the material is received by the second conveying device 30 and conveyed out with the set target facing forward, ensuring that the material can always be conveyed out with the set target facing forward.

[0053] In this embodiment, the guide surface 81 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 second conveying device 30. 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 81 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 second conveying device 30.

[0054] In this embodiment, the transfer structure 80 is an arc-shaped slide provided with the arc-shaped surface. This structure is simple and practical, occupies little space, and is convenient to manufacture and assemble.

[0055] In this embodiment, the second conveying device 30 is provided with a material blocking plate 34 located behind the transfer structure 80 , and the material blocking plate 34 is used to block the material conveyed from the transfer structure 80 to prevent the material from sliding down, so that the material can be smoothly conveyed through the second conveying device 30 .

[0056] In this embodiment, the third conveying device 60 is a retractable belt conveying device. When the visual inspection device 70 detects that the material is not in the set state, the front end of the retractable belt conveying device retracts in the direction away from the rear end of the first conveying device 20 and is separated from the first conveying device 20 by a distance and forms a material outlet, so that the material can be conveyed to the transfer structure 80 through the material outlet. After the set time, the front end of the retractable belt conveying device stretches in the direction close to the first conveying device 20 and resets to be connected with the first conveying device 20, so that the material can be conveyed out through the first conveying device 20 in the set state. In other embodiments, the third conveying device 60 is a swingable belt conveying device. When the visual inspection device 70 detects that the material is not in the set state, the front end of the swingable belt conveying device is driven to swing downward and is separated from the first conveying device 20 by a distance and forms a material outlet, so that the material can be conveyed to the transfer structure 80 through the material outlet. After the set time, the front end of the swingable belt conveying device is driven to swing upward and reset to be connected with the rear end of the first conveying device 20, so that the material can be conveyed out through the first conveying device 20 in the set state.

[0057] In this embodiment, the first conveying device 20, the second conveying device 30 and the third conveying device 60 are all belt conveying devices, which are simple and practical in structure, low in cost, and easy to maintain and repair. In other embodiments, the second conveying device 30 and the third conveying device 60 are all chain plate conveying devices or roller conveying devices.

[0058] The present invention also provides an application method of the material conveying device, comprising the following steps:

[0059] The second detection device 50 detects whether there is material passing through the second conveying device 30. If there is material passing through, the second detection device 50 sends a control instruction to the control device, and the control device controls the first detection device 40 to start according to the control instruction;

[0060] The first detection device 40 detects whether there is material passing through the first conveying device 20. If there is material passing through, the first detection device 40 sends a control instruction to the control device, and the control device controls the first conveying device 20 to shut down according to the control instruction.

[0061] More specifically, after the second detection device 50 detects that material has passed through the second conveying device 30 , the control device controls each first detection device 40 to start in sequence from front to back, and the control device shuts down each first conveying device 20 in sequence according to the control instructions of each first detection device 40 .

[0062] The activation and detection sequence of each first detection device 40 is as follows:

[0063] After the second detection device 50 detects that material has passed through the second conveying device 30, the control device first controls the first detection device 40 located at the front to start, and the first detection device 40 located at the front detects whether material has passed through the first conveying device 20 located at the front. If it is detected that material has passed through the first conveying device 20, a control instruction is sent to the control device, and the control device controls the first conveying device 20 to shut down;

[0064] After the first detection device 40 at the front has finished detecting, the control device controls the first detection device 40 in the middle to start, and the first detection device 40 in the middle detects whether there is material passing through the first conveying device 20 in the middle. If there is material passing through, the control device controls the corresponding first conveying device 20 to shut down;

[0065] After the first detection device 40 located in the middle completes the detection, the control device controls the first detection device 40 located at the rear to start, and the first detection device 40 located at the rear detects whether there is material passing through the first conveying device 20 located at the rear. If material passes through, the control device controls the corresponding first conveying device 20 to shut down, so that each first conveying device 20 with material passing through pauses in conveying the material, and after the material on the second conveying device 30 is conveyed out (that is, after the set time is reached), the control device controls each first conveying device 20 to start and convey the material out in sequence, which can avoid material stacking and enable efficient material conveying.

[0066] 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.
