[0001] The invention relates to the technical field of workpiece conveying, and in particular to a workpiece reversing device and a workpiece swinging device having the device. Background Art

[0002] In the process of workpiece processing, it is usually necessary to place the workpieces according to certain rules and order before conveying them to the processing station. When the workpieces are conveyed to the storage tray for swinging, the workpieces are piled together in the storage box during feeding. Therefore, during the conveying process, the conveying direction of the workpiece may not meet the swinging standard. Therefore, it is necessary to adjust the workpieces that do not meet the swinging direction standard before conveying them to the storage tray. At present, the following methods are used for the processing of workpiece reversing: 1. A clamping device is set during the conveying process of the workpiece, and the direction of the workpiece is adjusted by clamping and steering. Since the clamping device needs to clamp the workpiece firmly, a large force will be used, which will cause a certain degree of wear on the surface of the workpiece, reducing the product quality; 2. The direction of the workpiece that does not meet the swinging requirements is manually adjusted during the conveying process. When there are many swinging materials, the manual adjustment method takes a long time and does not meet the production capacity requirements.

[0016] A workpiece swinging device comprises a workpiece reversing device, wherein the workpiece reversing device is the workpiece reversing device described above.

[0018] 1. The present invention provides a workpiece reversing device, comprising: a transmission unit for conveying the workpiece; an output mechanism, arranged on the transmission unit, the output mechanism comprising a plurality of output channels and a reversing unit arranged on each of the output channel paths, the reversing unit adjusting the output direction of the workpiece. By arranging the output mechanism on the transmission unit, when the workpiece is conveyed on the output channel, the direction can be adjusted during the conveying process by arranging the reversing unit, and the conveying in the output channel is not delayed, thus overcoming the defect of using an external clamping device to clamp the workpiece and causing the surface to wear, and avoiding the quality reduction of the workpiece due to clamping; a reversing unit is arranged on the conveying path of each output channel, avoiding manual adjustment of the direction of the workpiece, and improving the production capacity of the workpiece.

[0019] 2. In a workpiece reversing device provided by the present invention, the output mechanism further comprises a reversing channel bypassing the output channel, and the reversing unit is arranged at the intersection of the reversing channel and the output channel. The reversing unit is arranged at the intersection of the output channel and the reversing channel, and the direction of the workpiece is adjusted by the reversing unit at the intersection, which is simple to operate.

[0020] 3. In a workpiece reversing device provided by the present invention, the reversing unit includes a pair of limit members located at the intersection, a pair of the limit members are arranged at the entrance of the reversing channel, and the opening between the pair of limit members limits the entry of the second end of the workpiece.

[0046] Example

[0047] This embodiment provides a workpiece swinging device, such as Figure 1 As shown, the workpiece swinging equipment includes a base 5 and a workpiece feeding device, a workpiece reversing device and a workpiece picking device 6 arranged on the base 5. The workpiece feeding device includes a plurality of feeding troughs. The workpiece is conveyed to the workpiece reversing device in the feeding trough, reversed in the reversing device and continued to be conveyed to the storage tray. The workpiece picking device 6 includes a picking arm 61. The picking arm 61 is used to take the workpiece from the storage tray and place the workpiece in the swinging tray according to the prescribed workpiece placement order, so that the output workpieces all meet the requirements of the swinging direction and are smoothly conveyed to the next workstation.

[0048] like Figure 1 and Figure 2 As shown, the workpiece reversing device in this embodiment is now described, including a transmission unit 1 for conveying the workpiece, and an output mechanism 2 arranged in sequence along the transmission direction of the workpiece, the output mechanism is arranged on the above-mentioned transmission unit 1, see the attached Figure 2-Figure 4 The output mechanism 2 includes a plurality of output channels 22 and a reversing unit 21 arranged in the path of each output channel 22. The reversing unit 21 is used to adjust the output direction of the workpiece. The transmission unit 1 includes a plurality of parallel conveying channels. The outlet end of the conveying channel is arranged one-to-one with the inlet end of the output channel 22. The workpiece enters the inlet end of the output channel 22 from the outlet end of the conveying channel, and enters the output channel 22 along the inlet end for conveyance. Specifically, the output mechanism 2 in this embodiment includes a plurality of reversing bases 3 arranged at intervals, and an output channel 22 is formed between the opposite end faces of adjacent reversing bases 3.

[0049] In this embodiment, the output mechanism 2 also includes a reversing channel 23, and the reversing channel 23 and the output channel 22 are arranged in a bypass manner. The reversing unit 21 is arranged at the intersection of the reversing channel 23 and the output channel 22. Each output channel 22 includes a feed channel 221 and a discharge channel 222. The discharge channel 222 is located downstream of the feed channel 221. The reversing channel 23 is located at the intersection of the discharge channel 222 and the feed channel 221. The workpiece is input from the feed channel 221 and then output to the storage tray along the discharge channel 222. The reversing unit 21 includes a pair of limit members 211 located at the intersection. The pair of limit members 211 are arranged at the entrance of the reversing channel 23. The limit member 211 in this embodiment is a limit plate, wherein the limit plate is perpendicular to the inner wall of the channel and fixed on the inner wall of the channel, and the opening between the pair of limit plates limits the entry of the second end of the workpiece.

[0050] The workpiece of this embodiment includes a first end and a second end, and the first end and the second end have different sizes. Fig.11 As shown, in this embodiment, the size of the first end of the workpiece is smaller than the size of the second end. When the workpiece is conveyed to the position of the limit plate of the reversing channel 23, the reversing channel 23 allows the first end to enter and restricts the second end from entering. During the conveying process of the workpiece, when the workpiece is in a state where the first end of the workpiece is conveyed downward into the feed channel, the workpiece in this state does not meet the requirements of the swinging direction. At this time, when the workpiece moves into the reversing channel 23, the first end of the workpiece will enter the reversing channel 23, and the second end will not enter the reversing channel 23 due to the blocking effect of the limit plate. Due to the effect of gravity, the second end is heavier than the first end , so the second end will flip relative to the first end, thereby reversing the direction, and the second end will enter the first end of the discharge channel first and then the discharge channel, realizing the reversing effect of the workpiece. After the reversal, the second end of the workpiece is located in front of the first end and is transported in the discharge channel 222 and output to the storage tray; during the conveying process of the workpiece, when the workpiece is in the second end facing downward to enter the feed channel, the workpiece in this state meets the requirements of the swinging direction. When the workpiece is conveyed to the limit plate, the second end will not enter the reversing channel 23, so no reversing action will occur, and it will continue to be conveyed to the discharge channel 222 to complete the conveying of the workpiece. As a convertible embodiment, it is also possible to set the reversing channel 23 to an open type, so that the first end can enter its body, and the second end cannot enter its body.

[0051] like Figure 4-Figure 5 As shown, in order to control the moving speed of the workpiece in the output channel 22, as shown in FIG. Figure 1As shown, the reversing unit 21 also includes an auxiliary part 212 and a driving assembly 213. A moving cavity 31 is opened at the same position on each reversing base 3 for the auxiliary part 212 to reciprocate therein. In this embodiment, the auxiliary part 212 is located at the upper end of the limit plate, and the power output end of the driving assembly 213 is connected to the auxiliary part 212 to drive the auxiliary part 212 to move closer to and away from the limit plate. Specifically, the auxiliary part 212 can be set as an auxiliary plate, and the moving cavity 31 is a cavity suitable for inserting the auxiliary plate. The driving assembly 213 is fixed on the frame, which can be a driving cylinder. The power output end of the driving cylinder is fixedly connected to one end of the auxiliary plate. The auxiliary plate is driven to move up and down in the moving cavity 31 through the power output end to achieve the effect of the auxiliary plate moving closer to and away from the limit plate. When the workpiece is transported to the position of the limit plate, the auxiliary plate blocks the workpiece, and then when the power output end of the driving cylinder is retracted, the workpiece slides along the auxiliary plate into the discharge channel 222.

[0052] Avoid the problem that two workpieces are transported to the storage tray closely and continuously, resulting in the storage tray being unable to provide empty storage trays for workpieces to enter, such as 1. Figure 2 , Figure 7 , Figure 8 , Fig. 9 As shown, the workpiece reversing device also includes a material blocking mechanism 4, which is correspondingly arranged along the outlet end of the output channel 22, and includes a material blocking body 42 and a material blocking drive assembly 43. A accommodating cavity 41 is formed on the material blocking body 42, and the accommodating cavity 41 is used to receive the workpiece output from the outlet end of the output channel 22. In this embodiment, the outlet end of the output channel 22 is the outlet end of the discharge channel 222, and the workpiece enters the accommodating cavity 41 of the material blocking body 42 after being output from the discharge channel 222. The material blocking drive assembly 43 includes a material blocking member 431 and a material blocking drive member 432. The material blocking member 431 can be a material blocking plate, and a material blocking portion 433 adapted to the accommodating cavity 41 is provided on the plate body of the material blocking plate. The material blocking drive member 432 can be a driving cylinder, and its power output end is connected to one end of the material blocking plate to drive the material blocking plate relative to the material blocking body. The material baffle plate 433 moves with the material baffle body 42. Specifically, the material baffle plate can be attached to the material baffle body 42. When the workpiece is conveyed to the accommodating cavity 41 of the material baffle body 42, the driving cylinder drives the material baffle plate to move, so that the material baffle portion 433 completely covers the accommodating cavity 41. When an empty material storage tray is provided to the corresponding position of the accommodating cavity 41, the driving cylinder retracts the material baffle plate, so that the material baffle portion 433 is completely moved away from the accommodating cavity 41, and the workpiece is output from the accommodating cavity 41 and enters the material storage tray. The conveying process is more reasonable, the structure is simple, and the practicality is stronger.

[0053] In this embodiment, the workpiece is a special-shaped workpiece, for example, a column with a mass center and a gravity center at different points.

[0054] The working process of this embodiment:

[0055] A plurality of workpieces are placed into the feeding trough of the feeding device, and enter the output channel 22 of the reversing device one by one from the feeding trough, wherein the workpieces pass through the feeding channel 221, the reversing channel 23 and the discharging channel 222 in sequence to complete the reversing and conveying work. The workpieces are reversing in the reversing channel 23. During the conveying process of the workpieces, when the workpieces are in a state where the first end is conveyed in front of the second end, the workpieces in this state do not meet the requirements of the swinging direction. When the workpieces are conveyed into the reversing channel 23, the first end of the workpieces will enter the reversing channel 23, and the second end will be moved due to the limit. The blocking effect of the plate will prevent it from entering the reversing channel 23, and then the second end will flip relative to the first end, realizing the reversing effect of the workpiece, and after the reversing, the second end of the workpiece is located in front of the first end and is transported in the discharge channel 222 and output to the storage tray; in the conveying process of the workpiece, when the workpiece is in a state where the second end is transported in front of the first end, the workpiece in this state meets the requirements of the swinging direction, and when the workpiece is conveyed to the limit plate, the second end will not enter the reversing channel 23, so no reversing action will occur, and it will continue to be transported to the discharge channel 222 to complete the conveying of the workpiece.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
