Description

Technical Field

[0001] This application relates to the field of conveying technology, and in particular to a limiting conveying device. Background Technology

[0002] During the production process, the conveyor moves the pallet. The pallet needs to stop when it reaches the appropriate position. Existing technologies often use cylinders or other actuators to stop the pallet from moving. However, when there are a large number of pallets, an equal number of actuators are needed to cooperate with them, which leads to a high cost of the conveyor. Utility Model Content

[0003] To address the shortcomings of existing technologies, one objective of this application is to provide a limiting conveying device that uses the movement of the pallet to switch the state of the blocking facility to stop the pallet from moving, eliminating the need for an actuator and thus reducing the cost of the conveying device.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A limiting conveying device includes a frame, on which a conveying component, a braking component, and a baffle are provided. The conveying component is used to drive a pallet to move, the braking component is used to limit the position of the pallet, and the baffle is used to keep the pallet at a specified position. The braking component includes a blocking end and a control end. The blocking end is used to limit the movement of the pallet on its movement path, and the control end is used to adjust the position of the blocking end. When the control end contacts the pallet, the blocking end tilts up to prevent the movement of the next pallet.

[0006] By adopting the above technical solution, under the action of gravity, the control end is in a tilted state, and the blocking end is located below the pallet. When the conveying component drives the pallet to contact the control end, the control end moves downwards from the conveying plane, and the blocking end is in a tilted state. When the front pallet reaches the designated position, the baffle limits the position of the front pallet of the conveying component, so that the tilted blocking end no longer descends, thereby preventing the rear pallet from continuing to move. By cooperating with the blocking end and the control end, without setting up an execution structure, the movement of the pallet can be used to achieve the purpose of switching the state of the blocking end, so that the blocking end prevents the pallet from moving, making the cost of the conveying device lower.

[0007] In a preferred embodiment, the present application may be further configured such that: the braking assembly includes a connecting shaft and a rotating plate, with a stopping end and a control end located at both ends of the rotating plate, and the connecting shaft is used to rotatably connect with the rotating plate and to the frame.

[0008] By adopting the above technical solution, the rotating plate and the connecting shaft are rotatably connected, so that the blocking end and the control end are rotatably connected to the connecting shaft, thereby enabling the blocking end and the control end to switch states by rotation when the tray moves.

[0009] In a preferred embodiment, the present application may be further configured such that the braking assembly includes a connecting portion, and the connecting shaft is connected to the frame via the connecting portion.

[0010] In a preferred embodiment, this application can be further configured such that: the connecting part includes a connecting plate and a support plate, the connecting shaft is mounted on the support plate, the support plate is mounted on the connecting plate, and the connecting plate is connected to the frame.

[0011] In a preferred embodiment, this application can be further configured such that: the connecting plate is provided with an adjustment hole one, which is used to adjust the relative position between the connecting plate and the frame; and the support plate is provided with an adjustment hole two, which is used to adjust the position between the connecting plate and the support plate.

[0012] By adopting the above technical solution, adjusting hole one adjusts the relative position between the connecting plate and the frame, making the lateral position of the rotating plate more suitable, and adjusting hole two adjusts the position between the connecting plate and the support plate, making the vertical position of the rotating plate more suitable.

[0013] In a preferred embodiment, this application may be further configured such that the control terminal has a weight-reducing hole for reducing the weight of the control terminal.

[0014] By adopting the above technical solution, the weight reduction hole reduces the weight of the control end, allowing the control end to be in an extended state under the action of gravity, thereby placing the blocking end below.

[0015] In a preferred embodiment, this application may be further configured such that the control end has a guide surface for cooperating with the tray as it passes over the conveying assembly.

[0016] By adopting the above technical solution, the guide surface cooperates with the pallet to pass through the conveying component, making it easier for the control end to rotate when the pallet passes through the conveying component.

[0017] In a preferred embodiment, this application can be further configured such that the blocking end has a transition surface, which is used to reduce the contact area between the blocking end and the tray.

[0018] By adopting the above technical solution, the transition surface is used to reduce the contact area between the blocking end and the pallet, making it easier for the blocking end to rotate below the conveying plane. Attached Figure Description

Detailed Implementation

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 4 The present application discloses a limiting conveying device, which includes a frame 1. The frame 1 is provided with a conveying component 2, a baffle 8 and several sets of braking components 3. The conveying component 2 is used to drive the pallet 10 to move. In this embodiment, the conveying component 2 can be a belt conveyor. The plane in contact with the pallet 10 by the belt conveyor is the conveying plane 21. The braking components 3 are used to limit the position of the pallet 10 on the conveying plane 21. The baffle 8 is used to limit the position of the pallet 10 at the front end of the conveying component 2.

[0026] The braking assembly 3 includes a blocking end 4, a control end 5, a connecting shaft 6, a rotating plate 7, a baffle 8, and a connecting part 9. The blocking end 4 and the control end 5 are located at both ends of the rotating plate 7. The blocking end 4 is heavier than the control end 5, so that the control end 5 is in a tilted state in its natural state. The control end 5 is used to adjust the position of the blocking end 4. When the control end 5 contacts the tray 10, the blocking end 4 tilts up to prevent the next tray 10 from moving forward. The connecting shaft 6 is used to rotatably connect with the rotating plate 7 and to the frame 1. The connecting shaft 6 is connected to the frame 1 through the connecting part 9. In this embodiment, the number of rotating plates 7 can be set to two sets. A bearing can be set between the connecting shaft 6 and the rotating plate 7. One set of the braking assembly 3 is provided with a baffle 8. The baffle 8 is installed on the connecting part 9 to limit the position of the foremost tray 10.

[0027] The connecting part 9 includes a connecting plate 91 and a support plate 92. The connecting shaft 6 is mounted on the support plate 92, and the support plate 92 is mounted on the connecting plate 91. The connecting plate 91 is connected to the frame 1. The connecting plate 91 is provided with an adjustment hole 93, which is used to adjust the relative position between the connecting plate 91 and the frame 1. The support plate 92 is provided with an adjustment hole 94, which is used to adjust the position between the connecting plate 91 and the support plate 92.

[0028] The control terminal 5 is provided with a weight reduction hole 51 and a guide surface 52. The weight reduction hole 51 is used to reduce the weight of the control terminal 5. In this embodiment, the number and specifications of the weight reduction hole 51 can be set according to actual needs. The guide surface 52 is used to cooperate with the tray 10 to pass through the conveying assembly.

[0029] The blocking end 4 is provided with a transition surface 41, which is used to reduce the contact area between the blocking end 4 and the tray 10. For example, the transition surface 41 makes the blocking end 4 and the tray 10 make point contact or line contact, thereby reducing the contact area between the blocking end 4 and the tray 10, making it easier for the blocking end 4 to rotate to the bottom of the conveying plane 21.

[0030] When the conveying assembly 2 moves several pallets 10, the control end 5 of the pallet 10 is not in the tilted state (the tilted state means that one end is higher than the conveying plane). When the pallet 10 moves to the control end 5, the guide surface 52 contacts the pallet 10 and guides the pallet 10 to cover the control end 5, causing the rotating plate 7 to rotate, so that the control end 5 is below the conveying plane 21 and the blocking end 4 is in the tilted state. When the pallet 10 leaves the control end 5, the rotating plate 7 rotates under the action of gravity, so that the control end 5 is in the extended state. The transition surface 41 reduces the contact area between the blocking end 4 and the pallet 10, making it easier for the blocking end 4 to rotate to the bottom of the conveying plane 21, so that the pallet 10 can continue to pass. When the first pallet 10 abuts against the baffle 8, the baffle 8 limits the position of the first pallet 10 on the conveying plane 21. At this time, the blocking ends 4 on all braking assemblies 3 are in the extended state and will not descend further, so that the blocking ends 4 prevent the pallet 10 from moving.

[0031] The implementation principle of this embodiment is as follows: Since the weight of the blocking end 4 is greater than that of the control end 5, the control end 5 is tilted up under the action of gravity, and the blocking end 4 is located below the tray 10. When the conveying component 2 drives the tray 10 to contact the control end 5, the control end 5 moves downward to the conveying plane 21, and the blocking end 4 is tilted up. When the front tray 10 reaches the designated position, the baffle 8 limits the position of the front tray 10 of the conveying component 2, so that the tilted blocking end 4 no longer falls down, thereby preventing the rear tray 10 from continuing to move. By cooperating with the blocking end 4 and the control end 5, without setting up an execution structure, the movement of the tray 10 can be used to achieve the purpose of switching the state of the blocking end 4, so that the blocking end 4 prevents the tray 10 from moving, making the cost of the conveying device lower.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
