Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a feeding device. Background Art

[0002] Roller conveyor belts are composed of rollers, bearings and frames. They are essential equipment for conveying items in assembly lines, automation equipment and logistics equipment.

[0003] For example, Chinese patent CN214904292U discloses an adjustable roller conveyor belt, which rotatably connects the flat section support frame and the curved section support frame by setting a groove block and a rotating connecting piece. By setting a jack in the connecting groove of the first support column and the second support column, it is convenient to change the conveying height of the conveying roller in the curved section support frame, so that the roller conveyor belt can be adjusted according to the actual use site, making it more convenient to use and enhancing practicality.

[0004] However, when the weight of the conveyed object is relatively large, the inertia of the conveyed object is also relatively large. The traditional roller conveyor belt is prone to slippage with the conveyed object, resulting in slow start-up of the conveyor and failure to stop in time after the conveyor reaches the designated position, thereby reducing the conveying efficiency and conveying accuracy of the conveying device. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention lies in the roller conveyor belt in the prior art. When the weight of the conveyed object is relatively large, the inertia of the conveyed object is also relatively large. Slipping is likely to occur between the traditional roller conveyor belt and the conveyed object, resulting in slow start-up of the conveying and failure to stop in time after the conveying is in place, resulting in reduced conveying efficiency and conveying accuracy of the conveying device.

[0006] To this end, the utility model provides a feeding device, comprising:

[0007] scaffolding;

[0008] A conveying member is mounted on the upper end of the base frame and is suitable for carrying the member to be conveyed;

[0009] The positioning conveying assembly includes a guide member, a driving member, and a fixing member; the guide member is arranged on the base frame along the conveying direction of the conveying member, the fixing member and the guide member are slidably arranged, and the driving member is transmission-connected to the fixing member;

[0010] The fixing member is suitable for fixing or releasing the object to be conveyed, and the fixing member is driven by the driving member to drive the object to be conveyed to move along the conveying direction on the conveying member.

[0011] In the above structure, when transporting an object to be conveyed, the object to be conveyed is placed on the conveying member, specifically at the front end of the object to be conveyed. The object to be conveyed is then fixed by a fixing member at the front end of the object to be conveyed. The fixing member is then driven by a driving member to move along the guide member toward the rear end of the conveying member until the object to be conveyed is transported to a set position, after which the fixing member releases the object to be conveyed. By providing a fixing member to fix the object to be conveyed and drive the movement of the object to be conveyed, it is possible to prevent the object from slipping between the object to be conveyed and the conveying member when the object is heavy, resulting in slow start-up of the conveying and failure to stop in time after delivery, thereby reducing the conveying efficiency and conveying accuracy of the conveying device.

[0012] As an embodiment, the loading device further comprises a stopper, which is mounted on the base frame and located at the end side of the conveying member;

[0013] The stopper is configured to provide an escape space for the conveyed object to pass through when the conveyed object moves along the conveying direction;

[0014] The stopper is further configured to block the object to be conveyed when the object to be conveyed moves in a direction opposite to the conveying direction.

[0015] By setting a stopper installed on the base frame and located at the end side of the conveying member, when the member to be conveyed is moved along the conveying direction, the stopper can provide an avoidance space for the member to be conveyed to pass through, so as to avoid obstruction to the conveying of the member to be conveyed; and when the member to be conveyed moves in the opposite direction to the conveying direction, the stopper can block the member to be conveyed, so as to prevent the member to be conveyed from moving in the opposite direction.

[0016] As an embodiment, the stopper includes a telescopic member and an action member, wherein the fixed end of the telescopic member is fixedly connected to the base frame, and the action member is installed at the movable end of the telescopic member;

[0017] The telescopic member is configured to drive the actuating member downward to provide an escape space for the conveyed member to pass through;

[0018] The telescopic member is further configured to drive the acting member to rise so as to limit the reverse movement of the member to be transported.

[0019] The rising and falling movements of the acting member are controlled by the telescopic member, so as to realize the blocking and avoiding functions of the acting member, and the structure is simple and the blocking effect is good.

[0020] As an embodiment, the active member includes a base and an abutment member, the first end of the abutment member is rotatably mounted on the base via a rotating shaft, the movable end of the telescopic member passes through the base and is connected to the second end of the abutment member, and the telescopic member is configured to drive the abutment member to rotate around the rotating shaft to control the abutment member to switch between high and low positions.

[0021] The telescopic member drives the abutment member to rotate around the rotation axis to switch between the high and low positions, which shortens the movement distance of the telescopic member and reduces the switching time of the abutment member between the high and low positions.

[0022] As an embodiment, the fixing member includes a main body portion and a moving portion, the main body portion and the guide member are slidably arranged, and the moving portion is movably connected to the main body portion;

[0024] The moving portion is further configured to be retracted relative to the main body portion so as to be separated from the object to be transported.

[0025] The sliding arrangement of the main body and the guide member enables the main body to run smoothly during movement; the design that the moving part can extend or retract relative to the main body enables rapid switching to ensure a fixed or separated state with the object to be transported.

[0026] As an embodiment, the loading device also includes a positioning component, the positioning component includes a lifting member and a first positioning member, the fixed end of the lifting member is installed on the base frame, the first positioning member is installed on the driving end of the lifting member, and a first positioning hole is opened at the bottom of the member to be conveyed. The lifting member is configured to drive the first positioning member to rise to cooperate with the first positioning hole to limit the member to be conveyed carried by the conveying member.

[0027] The positioning member is used to limit the position of the workpiece to be conveyed carried by the conveying member, thereby improving the conveying accuracy of the workpiece to be conveyed.

[0028] As an embodiment, the loading device further includes a lifting assembly, which is arranged at the end of the conveying member;

[0029] The lifting assembly is configured to receive the workpiece to be conveyed conveyed by the positioning and conveying assembly and drive the workpiece to be conveyed to rise and fall.

[0031] As an embodiment, the lifting assembly includes a lifting drive member, a lifting plate and a second positioning member. The second positioning member is fixedly mounted on the lifting plate. A second positioning hole is provided at the bottom of the member to be conveyed. The second positioning member cooperates with the second positioning hole to limit the member to be conveyed. The driving end of the lifting drive member is transmission-connected to the lifting plate. The lifting drive member is configured to drive the lifting plate and the member to be conveyed after being limited to move up and down.

[0034] The universal wheels can reduce the friction during the movement of the conveyed parts, so as to achieve the effect of smoother conveying of the conveyed parts.

[0035] As an embodiment, the positioning and conveying components and the conveying members are matched and arranged at opposite ends of the object to be conveyed, and the two sets of positioning and conveying components and the conveying members cooperate synchronously to convey the same object to be conveyed.

[0036] By using two sets of positioning and conveying components and conveying parts to synchronously convey the same piece to be conveyed, a more stable conveying effect of the piece to be conveyed is achieved, ensuring the conveying accuracy.

[0053] Example

[0054] This embodiment provides a feeding device, such as Figures 1 to 5 As shown, it includes a base frame 1, a conveying member 2, a positioning and conveying component 3, a stopper 4, a positioning component and a lifting component 5.

[0055] In this embodiment, the conveying member 2 is installed at the upper end of the base frame 1, and the conveying member 2 is suitable for carrying the member to be conveyed; the positioning conveying assembly 3 includes a guide member 31, a driving member 32 and a fixing member 33; the guide member 31 is arranged on the base frame 1 along the conveying direction of the conveying member 2, the fixing member 33 is slidingly arranged with the guide member 31, and the driving member 32 is transmission-connected with the fixing member 33; wherein, the fixing member 33 is suitable for fixing or releasing the member to be conveyed, and the fixing member 33 is driven by the driving member 32 to drive the member to be conveyed to move along the conveying direction on the conveying member 2.

[0056] In the above structure, when transporting the object to be conveyed, the object to be conveyed is placed on the conveying member 2, specifically at the front end of the object to be conveyed, and then the object to be conveyed can be fixed by the fixing member 33 at the front end of the object to be conveyed, and then the fixing member 33 is driven by the driving member 32 to move along the guide member 31 toward the rear end of the conveying member 2 until the object to be conveyed is transported to the set position and the fixing member 33 releases the object to be conveyed. By setting the fixing member 33 to fix the object to be conveyed and drive the object to be conveyed to move, it can be avoided that when the weight of the object to be conveyed is relatively large, the object to be conveyed and the conveying member 2 are prone to slipping, resulting in slow start of conveying and failure to stop in time after being delivered to the destination, resulting in reduced conveying efficiency and conveying accuracy of the conveying device. Among them, the direction from the front end to the rear end of the object to be conveyed is the conveying direction of the conveying member 2.

[0057] Specifically, such as Figure 1 As shown, Figure 1 Taking the right side of the middle base frame 1 as an example, there are two conveyor members 2, arranged side by side with a gap between them. During use, the conveyor members 2 are suitable for carrying the object to be conveyed, and the ends of the object to be conveyed can be placed on the two conveyor members 2 to carry and transport the object. In this embodiment, the conveyor members 2 are composed of a plurality of freely rotatable rollers to ensure that the object to be conveyed can be transported on the roller surface. In other embodiments, the conveyor members 2 can also use existing conveying devices such as transmission belts.

[0058] like Figures 1 to 3 As shown, a positioning conveying assembly 3 is provided on the side of any conveying member 2, and a guide member 31 is provided on the base frame 1 along the conveying direction of the conveying member 2. The guide member 31 is used to limit the direction of the conveying member moving on the conveying member 2 to ensure that the conveying member can move along the preset direction; the fixing member 33 is slidingly arranged with the guide member 31, and the driving member 32 is connected to the fixing member 33.

[0059] As an implementation of this embodiment, a positioning hole is opened on the side of the conveying component 3 relative to the positioning part to be conveyed, and the fixing part 33 is configured to be inserted into the positioning hole to fix the conveying part to be conveyed. The fixing part 33 is also configured to be disengaged from the positioning hole to release the conveying part to be conveyed.

[0060] In this embodiment, the fixing member 33 includes a main body and a moving part. The main body is slidably arranged with the guide member 31, and the moving part is movably connected to the main body; the moving part is configured to extend relative to the main body to be fixed to the member to be transported; the moving part is also configured to retract relative to the main body to separate from the member to be transported. Among them, the main body can adopt a driver such as a cylinder or a motor, and the moving part can adopt a positioning member such as a positioning pin that can cooperate with the main body to perform telescopic movement. The main body drives the moving part to telescopic movement, and cooperates with the positioning hole on the member to be transported to achieve the fixing and release of the member to be transported. Of course, the fixing member 33 can adopt other types of telescopic members, which are not limited here. In addition, the driving member 32 can also adopt a cylinder or a motor in combination with a transmission belt or a screw rod and other structures to drive the fixing member 33 to move back and forth on the guide member 31.

[0061] In this embodiment, the stop member 4 is installed on the base frame 1 and is located on the end side of the conveying member 2; the stop member 4 is configured to provide an avoidance space for the conveying member to pass when the conveying member to be conveyed moves along the conveying direction; the stop member 4 is also configured to block the conveying member to be conveyed when the conveying member to be conveyed moves in the opposite direction to the conveying direction.

[0062] By setting a stopper 4 installed on the base frame 1 and located at the end side of the conveying member 2, when the member to be conveyed is moved along the conveying direction, the stopper 4 can provide an escape space for the member to be conveyed to pass through, so as to avoid obstruction to the conveying of the member to be conveyed; and when the member to be conveyed moves in the opposite direction to the conveying direction, the member to be conveyed is blocked to prevent the member to be conveyed from moving in the opposite direction.

[0063] Specifically, the stopper 4 includes a telescopic member and an actuator. The fixed end of the telescopic member is fixedly connected to the base frame 1, and the actuator is mounted on the movable end of the telescopic member. The telescopic member is configured to drive the actuator downward to provide a clearance space for the conveyed object to pass through. The telescopic member is also configured to drive the actuator upward to limit the reverse movement of the conveyed object. The telescopic member can use a component such as a cylinder to drive the actuator up and down.

[0064] In one embodiment, Figure 1 and Figure 4 As shown, the active member includes a base 41 and an abutment member 42. The first end of the abutment member 42 is rotatably mounted on the base 41 via a rotating shaft. The movable end of the telescopic member passes through the base 41 and is connected to the second end of the abutment member 42. The telescopic member is configured to drive the abutment member 42 to rotate around the rotating shaft to control the abutment member 42 to switch between high and low positions. For example, Figure 4In the embodiment, when the conveyed member moves in the conveying direction, the telescopic member drives the abutment 42 to rotate clockwise around the rotating shaft, and the abutment 42 enters a low position to provide a clearance space for the conveyed member to pass through. Conversely, when the conveyed member moves in the opposite direction of the conveying direction, the telescopic member drives the abutment 42 to rotate counterclockwise around the rotating shaft, and the abutment 42 enters a high position to block the conveyed member. Alternatively, when the conveyed member moves in the conveying direction, the conveyed member pushes the abutment 42 to rotate clockwise around the rotating shaft, and the abutment 42 enters a low position to provide a clearance space for the conveyed member to pass through. Conversely, when the conveyed member moves in the opposite direction of the conveying direction, the abutment 42 is driven by the return spring to rotate counterclockwise around the rotating shaft, and the abutment 42 enters a high position to block the conveyed member.

[0065] In other embodiments, the above-mentioned effect can also be achieved by directly using the telescopic member to drive the upward and downward movement of the actuating member. For example, when the object to be conveyed moves in the conveying direction, the telescopic member drives the actuating member downward, thereby providing a clearance space for the object to be conveyed to pass through; conversely, when the object to be conveyed moves in the opposite direction of the conveying direction, the telescopic member drives the actuating member upward, thereby blocking the object to be conveyed.

[0066] In this embodiment, the positioning assembly includes a lifting member and a first positioning member. The fixed end of the lifting member is installed on the base frame 1, and the first positioning member is installed at the driving end of the lifting member. A first positioning hole is opened at the bottom of the member to be conveyed. The lifting member is configured to drive the first positioning member to rise to cooperate with the first positioning hole to limit the member to be conveyed carried by the conveying member 2.

[0067] The positioning assembly is arranged at the front end of the conveying member 2, the fixed end of the lifting member is mounted on the base frame 1, and the first positioning member is mounted on the driving end of the lifting member, so that the lifting and lowering of the first positioning member can be controlled by the lifting member. When placing the member to be conveyed, the first positioning hole at the bottom of the member to be conveyed is aligned with the first positioning member to ensure that the first positioning member can be smoothly inserted into the first positioning hole. In this way, the placement position of the member to be conveyed is limited to ensure that the fixing member 33 can successfully complete the fixing of the member to be conveyed. Among them, before the member to be conveyed moves, the lifting member can control the first positioning member to be out of the first positioning hole. The lifting member can be a cylinder.

[0068] In this embodiment, if Figure 1 As shown, the lifting assembly 5 is arranged at the end of the conveying member 2 along the conveying direction of the conveying member 2. The lifting assembly 5 is configured to receive the object to be conveyed conveyed by the positioning conveying assembly 3 and drive the object to be conveyed to rise and fall.

[0069] When the object to be conveyed is delivered to the end of the conveying member 2 and reaches the set position, the lifting assembly 5 receives the object to be conveyed and drives the object to be conveyed to rise and fall.

[0070] Specifically, such as Figure 5As shown, the lifting assembly 5 includes a lifting drive member (not shown in the figure), a lifting plate 51 and a second positioning member 52. The second positioning member 52 is fixedly mounted on the lifting plate 51. A second positioning hole is provided at the bottom of the piece to be conveyed. The second positioning member 52 cooperates with the second positioning hole to limit the piece to be conveyed. The driving end of the lifting drive member is transmission-connected to the lifting plate 51. The lifting drive member is configured to drive the lifting plate 51 and the piece to be conveyed after being limited to move up and down.

[0071] By providing a second positioning member 52 on the lifting plate 51, after the workpiece is placed on the lifting plate 51, the second positioning member 52 is inserted into the second positioning hole to limit the position of the workpiece, ensuring that the workpiece enters the next process in the correct posture. Optionally, the second positioning member 52 can be a positioning pin or other positioning member; the lifting plate 51 is raised and lowered by the cooperation between the motor and the transmission chain, or the lifting drive member is a drive device such as a cylinder.

[0072] Furthermore, the lifting assembly 5 also includes a plurality of sets of universal wheels, which are installed on the lifting plate 51 along the conveying direction to facilitate the movement of the objects to be conveyed on the lifting plate 51.

[0073] In this embodiment, the positioning conveying assembly 3 and the conveying member 2 are matched and arranged at opposite ends of the object to be conveyed, and the two sets of positioning conveying assembly 3 and the conveying member 2 cooperate to convey the same object to be conveyed synchronously. Figure 1 In the figure, the conveying member 2 on the right is used to convey the workpiece to be conveyed toward the lifting assembly 5. After the lifting assembly 5 sends the workpiece to be conveyed to the processing station for completion of processing, the conveying member 2 on the left is used to send the processed workpiece out of the lifting assembly 5.

[0074] In other embodiments, the base frame 1, the conveying member 2 and the positioning conveying assembly 3 are symmetrically arranged on both sides of the lifting assembly 5, and the conveying members 2 on both sides cooperate with the corresponding positioning conveying assemblies 3 to convey the parts to be conveyed to the lifting assembly 5 respectively. Optionally, the parts to be conveyed conveyed by the conveying members 2 on both sides can be different materials.

[0075] The working process of the feeding device provided in this embodiment is as follows:

[0076] First, the workpiece to be conveyed is placed on the conveying member 2. At the same time, the positioning assembly limits the workpiece to be conveyed. Then, the fixing member 33 fixes the workpiece to be conveyed. The driving member 32 drives the fixing member 33 to move along the conveying direction on the conveying member 2. The stopper 4 provides a clearance space for the workpiece to be conveyed until the fixing member 33 conveys the workpiece to be conveyed to the lifting plate 51. The fixing member 33 releases the workpiece to be conveyed. Then, the second positioning member 52 precisely positions the workpiece to be conveyed on the lifting plate 51. The lifting driving member drives the lifting plate 51 upward and delivers the workpiece to be conveyed to the processing station. After the workpiece to be conveyed is processed, it is placed back on the lifting plate 51. The lifting driving member drives the lifting plate 51 downward. Then, the fixing member 33 fixes the processed workpiece to be conveyed. The driving member 32 drives the fixing member 33 to move along the discharge direction on the conveying member 2. The stopper 4 provides a clearance space for the processed workpiece to be conveyed until the fixing member 33 conveys the processed workpiece to be conveyed to the discharge position. The fixing member 33 releases the processed workpiece to be conveyed.

[0077] In one possible embodiment, the base frame, conveying parts and positioning conveying components are symmetrically arranged on both sides of the lifting component, and the conveying parts and positioning conveying components on both sides respectively convey different types of parts to be conveyed to the middle lifting component, and the two types of parts to be conveyed are successively conveyed to the processing station through the lifting component. The processed parts to be conveyed return to the lifting plate of the lifting component, and then the positioning conveying component on one side cooperates with the corresponding conveying parts to convey the processed parts to the next station.

[0078] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
