Description

Technical Field

[0001] The present invention belongs to the technical field of article conveying, and in particular relates to an article conveying device and an automatic article sending and receiving device. Background Art

[0002] In the field of goods processing, assembly line production is a very common operation method, where goods are transported by the conveyor belt on the assembly line. Generally, the conveyor belt can only play the role of conveying goods during the conveying operation. Since the conveyor belt rotates to convey goods, it is necessary to set a material unloading mechanism at the conveying end of the conveyor belt to unload the goods conveyed by the conveyor belt, or a special operator is required to collect the materials.

[0003] In the actual production process, not all materials conveyed by the conveyor belt need to be unloaded. For example, a production line may be processed twice by using the forward and reverse rotation of the conveyor belt, and the items are processed once when the conveyor belt conveys the items forward, and the items are processed a second time based on the previous processing step when the conveyor belt conveys the items reversely. In this way, if the items can be temporarily stored on the conveyor belt, the loading operation of the items can be omitted during the second processing, and the conveyor belt can be directly started to convey the items in the reverse direction. However, the conveying mechanism of the existing assembly line with the conveyor belt generally only has the function of conveying, and it cannot keep the items on the conveyor belt. Summary of the invention

[0004] The object of the present invention is to provide an article conveying device and an automatic article sending and receiving device, aiming to solve the technical problem that the conveyor belt mechanism in the prior art can only convey articles but cannot store articles.

[0005] To achieve the above object, the technical solution adopted by the present invention is: an article conveying device, comprising:

[0006] Mounting frame,

[0007] A conveying assembly, mounted on the mounting frame and used to convey articles, the conveying assembly comprising a conveyor belt wound around the mounting frame, the conveyor belt having a placement plane for placing articles;

[0008] A plurality of inductive stopper assemblies are installed on the mounting frame at intervals, and an article storage area for storing articles is formed between two adjacent inductive stopper assemblies. Each of the inductive stopper assemblies includes a sensor for sensing articles and a telescopic stopper for preventing the movement of articles. The telescopic stopper has a stopper arm which is arranged opposite to the storage plane and can rise or fall relative to the storage plane. When the sensor senses that an article enters the adjacent article storage area along the article conveying direction, the stopper arm of the corresponding telescopic stopper rises relative to the storage plane to stop the article from continuing to move.

[0009] Furthermore, each of the inductive stopper components is evenly spaced and installed on the mounting frame along the object conveying direction, thereby dividing the storage plane into a plurality of object storage areas of equal length.

[0010] Furthermore, the telescopic stopper is a pneumatic cylinder or a hydraulic cylinder electrically connected to the sensor, and a piston rod of the pneumatic cylinder or the hydraulic cylinder forms the stop arm.

[0011] Further, the mounting frame includes a first mounting member and a second mounting member arranged in parallel and at intervals, the conveyor belt includes a first synchronous belt wound around the first mounting member and a second synchronous belt wound around the second mounting member, the top surface of the first synchronous belt and the top surface of the second synchronous belt pass through the same plane and the top surfaces of the two together form the storage plane;

[0012] The mounting frame also includes a central mounting member clamped between the first mounting member and the second mounting member, the central mounting member is located below the storage plane, the central mounting member is provided with a mounting groove with a notch arranged toward the storage plane along the direction of article conveying, the induction stop assembly is installed in the mounting groove, and the stop arms of each telescopic stop member are arranged in a straight line at intervals, and the two sides of the storage plane are symmetrically arranged about a straight line passing through each stop arm.

[0013] Furthermore, a plurality of connecting plates are detachably connected to the slot ends of the mounting slots, and an installation gap is formed between the connecting plates and the storage plane. Each of the connecting plates is provided with a through hole, and each of the connecting plates corresponds one-to-one to each of the inductive stop assemblies, so that the stop arm of each of the telescopic stop members can pass through the corresponding through hole to stop the items on the storage plane.

[0014] Furthermore, the mounting frame also includes a first guide rail and a second guide rail, the first guide rail and the second guide rail are both provided with guide grooves parallel to the direction of article conveying, the first guide rail is installed on the first mounting member, the first synchronous belt is embedded in the guide groove of the first guide rail, the second guide rail is installed on the second mounting member, the second synchronous belt is embedded in the guide groove of the second guide rail, and the first guide rail and the second guide rail are both located below the storage plane.

[0015] Furthermore, the mounting frame also includes a first limit bar and a second limit bar which are arranged in parallel along the object conveying direction, the first limit bar is installed on the side of the first mounting member away from the central mounting member, and the second limit bar is installed on the side of the second mounting member away from the central mounting member, and the first limit bar and the second limit bar both protrude above the placement plane to correct the placement direction of the objects placed on the placement plane.

[0016] Furthermore, the transmission assembly also includes a first driving wheel, a second driving wheel, a first driven wheel, a second driven wheel and a driving motor, the first driving wheel and the first driven wheel are respectively rotatably mounted on two opposite ends of the first mounting member, the first synchronous belt transmission is connected between the first driving wheel and the first driven wheel, the second driving wheel and the second driven wheel are respectively rotatably mounted on two opposite ends of the second mounting member, the second synchronous belt transmission is connected between the second driving wheel and the second driven wheel, the driving motor is fixed to the side of the first mounting member / the second mounting member, and the first driving wheel and the second driving wheel are both connected to the driving motor.

[0017] Further, the transmission assembly further comprises a tension adjustment assembly, and the tension adjustment assembly comprises a first adjustment bolt, a second adjustment bolt and a tension shaft;

[0018] The end of the first mounting member connected to the first driven wheel is also connected to a first mounting plate, and the end of the second mounting member connected to the second driven wheel is also connected to a second mounting plate. The first mounting plate is provided with a first adjustment long hole extending along the article conveying direction, and the second mounting plate is provided with a second adjustment long hole extending along the article conveying direction. The two ends of the tensioning shaft are respectively inserted into the first adjustment long hole and the second adjustment long hole, and the first driven wheel and the second driven wheel are both rotatably mounted on the tensioning shaft.

[0019] The first adjusting bolt is screwed on the first mounting plate along the direction of article conveying, and the second adjusting bolt is screwed on the second mounting plate along the direction of article conveying. The ends of the first adjusting bolt and the second adjusting bolt are respectively connected to the two ends of the tensioning shaft. The first adjusting bolt and the second adjusting bolt can be screwed in or out relative to the corresponding first mounting plate and the second mounting plate, so that the two ends of the tensioning shaft move in the corresponding first adjusting long hole and the second adjusting long hole, thereby driving the first driven wheel and the second driven wheel to move along the direction of article conveying and adjusting the tension of the first synchronous belt and the second synchronous belt.

[0020] The above one or more technical solutions in the article conveying device provided by the present invention have at least one of the following technical effects: a plurality of inductive stop assemblies are installed on the mounting frame at intervals, and an article storage area is formed between two adjacent inductive stop assemblies; when in use, the articles are placed on the storage plane, and the conveyor belt moves while driving the articles to move; when the sensor of the inductive stop assembly at the end of the storage plane detects that the first article enters the article storage area in front of it, the stop arm of the corresponding telescopic stop member rises relative to the storage plane to block the first article, and the first article cannot continue to move due to being stopped by the stop arm and is limited to the article storage area at the end. In the storage area, similarly, when the sensor of the penultimate inductive stopper assembly detects that the second object has entered the object storage area in front of it, the stopper arm of the corresponding telescopic stopper also moves upward to stop the second object. In this way, the sensors of the inductive stopper assemblies on the mounting frame sequentially sense the third object, the fourth object to the nth object being transported in sequence along the object transmission direction, and the stopper arm of the corresponding telescopic stopper rises in sequence and limits the third object, the fourth object to the nth object in the corresponding object placement area. When all the object storage areas in the storage space have corresponding objects parked, the conveying assembly stops conveying the objects. In this way, the objects conveyed by the conveyor belt can be orderly limited and stored on the conveyor belt. The conveyor belt can also store objects while conveying. The functions of the conveyor belt are more diverse and flexible and convenient to use. In addition, the start and stop of the conveyor assembly can be controlled when switching the processing procedure, which can save the loading and unloading procedures when switching the processing procedure, and help reduce production costs and improve production efficiency.

[0021] Another technical solution of the present invention is an automatic article sending and receiving device, comprising the above-mentioned article conveying device.

[0022] The automatic article sending and receiving equipment of the present invention uses the above-mentioned article conveying device. When articles are received, the conveying component is started, and the conveyor belt transports the articles in sequence and stores each article in sequence in each article storage area. When feeding, the conveying component is restarted to sequentially convey each article stored on its upper part to the material taking mechanism. The receiving and sending of articles can be realized by starting and stopping the conveying component, and the use is flexible and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figures 1 to 4As shown, an embodiment of the present invention provides an article conveying device 100, which is suitable for conveying and storing articles 1. Article 1 can be, but is not limited to, a tray or box for holding knives or other rod-shaped materials. Specifically, the article conveying device 100 includes a mounting frame 10, a conveying assembly 20, and a plurality of inductive stop assemblies 30. The conveying assembly 20 is installed on the mounting frame 10 and is used to convey the article 1. The conveying assembly 20 includes a conveyor belt 21 wound around the mounting frame 10. The conveyor belt 21 has a placement plane (not shown) for placing the article 1. Specifically, the conveyor belt 21 is wound along the length direction of the mounting frame 10. The conveying assembly 20 is used to sequentially convey the article 1 from one end of the mounting frame 10 to the other end; each inductive stop assembly 30 is installed at intervals on the mounting frame 10. 0, and an article storage area 40 for storing articles 1 is formed between two adjacent inductive stopper assemblies 30, each inductive stopper assembly 30 includes a sensor 31 for sensing articles 1 and a telescopic stopper 32 for blocking the movement of articles 1, and the telescopic stopper 32 has a stopper arm 321 arranged opposite to the object placement plane and capable of rising or falling relative to the object placement plane, and when the sensor 31 senses that the article 1 enters the adjacent article storage area 40 along the conveying direction of the article 1, the stopper arm 321 of the corresponding telescopic stopper 32 rises relative to the object placement plane to stop the article 1 from continuing to move. It can be understood that, in this embodiment, a space capable of accommodating an article 1 is reserved between the inductive stopper assembly 30 closest to the front end of the conveyor belt 21 and the conveying start end of the conveyor belt 21, and although the space is not surrounded by two adjacent inductive stopper assemblies 30, it still belongs to the article storage area 40 and can be used to store the last article 1 placed on the conveyor belt 21.

[0049] In the article conveying device 100 of the embodiment of the present invention, a plurality of inductive stopper assemblies 30 are installed on the mounting frame 10 at intervals, and an article storage area 40 is formed between two adjacent inductive stopper assemblies 30; Figure 4 As shown, when in use, the object 1 is placed on the storage plane from the starting end of the conveyor belt 21. Figure 4 As shown in (a), the conveyor belt 21 moves while driving the objects 1 to move. When the sensor 31 of the inductive stopper assembly 30 at the end of the storage plane detects that the first object 1 enters the front object storage area 40, the stopper arm 321 of the corresponding telescopic stopper 32 moves upward relative to the storage plane to block the first object 1. The first object 1 cannot continue to move due to being stopped by the stopper arm 321 of the telescopic stopper 32 and is limited in the end object storage area 40. Figure 4As shown in (b), similarly, when the sensor 31 of the penultimate sensing stop assembly 30 detects that the second object 1 enters the object storage area 40 in front of it, the stop arm 321 of the corresponding telescopic stop member 32 also moves upward to stop the second object 1. In this way, the sensors 31 of each sensing stop assembly 30 on the mounting frame 10 sequentially sense the third object 1, the fourth object 1 to the nth object 1 conveyed in sequence along the transmission direction of the object 1, and the stop arm 321 of the corresponding telescopic stop member 32 rises in sequence and sequentially limits the third object 1, the fourth object 1 to the nth object 1 in the corresponding object storage area 40, as shown in FIG. Figure 4 As shown in (c) to (e), when all the object storage areas 40 in the storage space have corresponding objects 1, the conveying assembly 20 stops conveying the objects 1. In this way, the objects 1 conveyed by the conveyor belt 21 can be orderly stored on the conveyor belt 21. The conveyor belt 21 can store objects 1 while conveying, and the functions of the conveyor belt 21 are more diverse and flexible and convenient to use. In addition, when switching the processing steps, the conveying assembly 20 can be controlled to start and stop, which can save the loading and unloading steps when switching the processing steps, which helps to reduce production costs and improve production efficiency.

[0050] Furthermore, in this embodiment, each induction stop assembly 30 is installed on the mounting frame 10 at uniform intervals along the conveying direction of the object 1, thereby dividing the storage plane into a number of object storage areas 40 of equal length. Each object 1 is stored in the object storage area 40 at uniform intervals along the conveying direction of the object 1, and the objects 1 are stored in a regular, orderly, and neatly arranged manner.

[0051] Specifically, in this embodiment, the telescopic stopper 32 is a hydraulic cylinder or a pneumatic cylinder electrically connected to the sensor 31, and the piston rod of the hydraulic cylinder or the pneumatic cylinder forms the above-mentioned stopper arm 321 for stopping the object 1. The hydraulic cylinder or the pneumatic cylinder has a simple structure and is easy to use. More specifically, the sensor 31 is a laser sensor, an infrared sensor, an ultrasonic sensor, etc.

[0052] Furthermore, each sensing stop assembly 30 can also be provided with a single-chip microcomputer, PLC or other control element with relatively mature technology at present to communicate and connect the sensor 31 and the telescopic stop 32, so as to realize the automatic opening and closing of the telescopic stop 32. Alternatively, a central control device can also be provided, and each electric component of the article conveying device 100 of this embodiment is electrically connected to the central controller, so as to realize the start and stop and motion control of each electric component. Specifically, the central control device can be a single-chip microcomputer, PLC control device or computer with relatively mature technology at present, and the specific control of each electric component can be carried out by installing a program set or edited according to the control and usage requirements.

[0053] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, the mounting frame 10 includes a first mounting member 11 and a second mounting member 12 which are arranged in parallel and spaced apart and move synchronously (in the same direction and at the same speed), and the conveyor belt 21 includes a first synchronous belt 211 wound around the first mounting member 11 and a second synchronous belt 212 wound around the second mounting member 12. The top surface of the first synchronous belt 211 and the top surface of the second synchronous belt 212 pass through the same plane and the top surfaces of the two together form a storage plane. When conveying an object 1, the first synchronous belt 211 and the second synchronous belt 212 respectively support the opposite two sides of the object 1. The mounting frame 10 also includes a central mounting member 13 sandwiched between the first mounting member 11 and the second mounting member 12. The central mounting member 13 is located below the storage plane. The central mounting member 13 is provided with a mounting groove 131 with a notch arranged toward the storage plane along the conveying direction of the article 1. The induction stop assembly 30 is installed in the mounting groove 131, and the stop arms 321 of each telescopic stop member 32 are arranged at intervals in a straight line. The two sides of the storage plane are symmetrically arranged about a straight line passing through each stop arm 321, that is, the stop arms 321 of each telescopic stop member 32 are arranged opposite to the center line of the storage plane. In this way, the telescopic stop member 32 stops the article 1 from the middle part of the article 1, and the force on both sides of the article 1 is uniform, so that the article 1 can stay better in the article storage area 40.

[0054] Specifically, in this embodiment, Figures 1 to 3 As shown, the slot end of the mounting slot 131 is detachably connected to a plurality of connecting plates 132, and an installation gap (not shown) is formed between the connecting plates 132 and the storage plane. Each connecting plate 132 is provided with a through hole 1321, and each connecting plate 132 corresponds to each sensing stop assembly 30 one by one, so that the stop arm 321 of each telescopic stop member 32 can pass through the corresponding through hole 1321 to stop the object 1 on the storage plane, and each sensor 31 is respectively installed on the corresponding connecting plate 132 and is located in the installation gap.

[0055] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, a cover plate 133 is also provided in the installation gap, and the cover plate 133 is installed at the notch of the installation slot 131 to cover the installation slot 131. A clearance position (not shown) is provided on the cover plate 133 for avoiding the sensor 31 and the stop arm 321 of the telescopic stop member 32, so as to ensure that the sensor 31 can sense the object 1 quickly and accurately, and at the same time ensure that the stop arm 321 of the telescopic stop member 32 can pass through the cover plate 133 and stop the object 1.

[0056] In another embodiment of the present invention, Figures 1 to 3As shown, the mounting frame 10 also includes a first guide rail 14 and a second guide rail 15, both of which are provided with a guide groove 141 parallel to the conveying direction of the article 1, the first guide rail 14 is mounted on the first mounting member 11, the first synchronous belt 211 is embedded in the guide groove 141 of the first guide rail 14, the second guide rail 15 is mounted on the second mounting member 12, the second synchronous belt 212 is embedded in the guide groove 141 of the second guide rail 15, and the first guide rail 14 and the second guide rail 15 are both located below the storage plane. In this way, the first guide rail 14 and the second guide rail 15 are provided to guide and limit the first synchronous belt 211 and the second synchronous belt 212, so that the first synchronous belt 211 and the second synchronous belt 212 always move synchronously in the same direction, thereby ensuring the normal transportation of each article 1 on the storage plane.

[0057] In another embodiment of the present invention, Figures 1 to 3 As shown, the mounting frame 10 further includes a first limiting strip 16 and a second limiting strip 17 which are arranged in parallel along the conveying direction of the article 1. The first limiting strip 16 is installed on the side of the first mounting member 11 away from the central mounting member 13, and the second limiting strip 17 is installed on the side of the second mounting member 12 away from the central mounting member 13. The first limiting strip 16 and the second limiting strip 17 both protrude above the placement plane and are used to adapt and stop the opposite two sides of the article 1 located in the placement plane to correct the placement direction of the article 1 placed on the placement plane. When the article 1 is conveyed, its opposite two sides abut against the first limiting strip 16 and the second limiting strip 17 respectively. The first limiting strip 16 and the second limiting strip 17 work together to enable the article 1 to move only in a straight line along the conveying direction without displacement in other directions, thereby further ensuring that the article 1 can be conveyed to the designated position more accurately without positional displacement.

[0058] Preferably, in this embodiment, the first mounting member 11, the second mounting member 12, the central mounting member 13, the first limiting strip 16 and the second limiting strip 17 are all made of aluminum profiles, which are low in cost, light in weight and easy to use.

[0059] In another embodiment of the present invention, Figure 1 and Figure 2As shown, the transmission component 20 also includes a first driving wheel 22, a second driving wheel 23, a first driven wheel 24, a second driven wheel 25 and a driving motor 26. The first driving wheel 22 and the first driven wheel 24 are respectively rotatably mounted on the opposite ends of the first mounting member 11. The first synchronous belt 211 is transmission-connected between the first driving wheel 22 and the first driven wheel 24. The second driving wheel 23 and the second driven wheel 25 are respectively rotatably mounted on the opposite ends of the second mounting member 12. The second synchronous belt 212 is transmission-connected between the second driving wheel 23 and the second driven wheel 25. The driving motor 26 is fixed to the side of the first mounting member 11 / the second mounting member 12. The first driving wheel 22 and the second driving wheel 23 are both connected to the driving motor 26.

[0060] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the first driving wheel 22 and the second driving wheel 23 are located at the same end of the mounting frame 10, the first driving wheel 22 and the second driving wheel 23 are sleeved side by side on the rotating shaft 263 of the driving motor 26, the first driven wheel 24 and the second driven wheel 25 are installed at the other end of the mounting frame 10, the first side plate 261 is fixed to the side of the first mounting member 11, the second side plate 262 is fixed to the side of the second mounting member 12, the driving motor 26 is installed on the first side plate 261, and the rotating shaft 263 of the driving motor 26 passes through the first driving wheel 22 and the second driving wheel 23 and is rotatably connected to the second side plate 262. More specifically, in this embodiment, the driving motor 26 is preferably a right-angle reduction motor, which is flexible and convenient to install and can save installation space.

[0061] In another embodiment of the present invention, Figure 1 and Figure 2As shown, the transmission component 20 also includes a tension adjustment component 27 for adjusting the tension of the first synchronous belt 211 and the second synchronous belt 212. The tension adjustment component 27 includes a first adjustment bolt 271, a second adjustment bolt 272 and a tensioning shaft 273. Specifically, the end of the first mounting member 11 connected to the first driven wheel 24 is also connected to the first mounting plate 111, and the end of the second mounting member 12 connected to the second driven wheel 25 is also connected to the second mounting plate 121. The first mounting plate 111 is provided with a first adjustment long hole 1111 extending along the conveying direction of the article 1, and the second mounting plate 121 is provided with a second adjustment long hole 1211 extending along the conveying direction of the article 1. The two ends of the tensioning shaft 273 are respectively penetrated in the first adjustment long hole 1111 and the second adjustment long hole 1211. The first driven wheel 24 The first and second driven wheels 25 are both rotatably mounted on the tensioning shaft 273; the first adjusting bolt 271 is screwed on the first mounting plate 111 along the conveying direction of the article 1, and the second adjusting bolt 272 is screwed on the second mounting plate 121 along the conveying direction of the article 1. The ends of the first adjusting bolt 271 and the second adjusting bolt 272 are respectively connected to the two ends of the tensioning shaft 273. The first adjusting bolt 271 and the second adjusting bolt 272 can be screwed in or out relative to the corresponding first mounting plate 111 and the second mounting plate 121, so that the two ends of the tensioning shaft 273 move in the corresponding first adjusting long hole 1111 and the second adjusting long hole 1211, thereby driving the first driven wheel 24 and the second driven wheel 25 to move along the conveying direction of the article 1, and adjusting the tension of the first synchronous belt 211 and the second synchronous belt 212. In this way, when the first synchronous belt 211 or the second synchronous belt 212 becomes loose after long-term use, its tension can be adjusted by rotating the first adjusting bolt 271 and the second adjusting bolt 272. The adjustment structure is simple and easy to operate.

[0062] In addition, when the first adjusting bolt 271 and the second adjusting bolt 272 are synchronously adjusted to the same distance, the tensioning shaft 273 can be moved in a direction perpendicular to the transmission direction, so that the parallelism between the first driving wheel 22 and the first driven wheel 24, and the second driving wheel 23 and the second driven wheel 25 can be adjusted, ensuring that the first synchronous belt 211 and the second synchronous belt 212 are stable during rotation without left and right swing problems.

[0063] In another embodiment of the present invention, Figure 1 and Figure 2As shown, the mounting frame 10 is also equipped with an air pipe joint 18 and a terminal block 19. The air pipe joint 18 is used to adapt and plug in an external power supply cable. The telescopic stopper 32 and the drive motor 26 are electrically connected to the power supply cable through the terminal block 19.
