Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to a tray non-return mechanism. Background Art

[0002] In mechanical manufacturing, pallets on the assembly line often stay at the loading or processing station, waiting to grab parts or other operations. If the pallet reflows at this time, the following problems may occur: the pallet reflow will disrupt the normal operation rhythm of the assembly line, causing the pallets of the subsequent processes to fail to arrive on time, thereby causing production interruptions. This may reduce production efficiency and increase production costs. If the pallet reflow occurs when the parts have been grabbed on the pallet but have not yet been fixed or installed, the parts may fall due to the reflow, resulting in damage or loss of the parts. This may require additional repair work or re-acquisition of parts, increasing production costs and time. The pallet reflow may cause the pallet to collide with the equipment, causing equipment damage or failure. This not only requires downtime for maintenance, but may also affect the execution of the production plan. In addition, if the pallet reflow occurs during the processing process, it may also cause the unfinished products to be mistakenly transferred to the next process, thereby affecting product quality. The existing technology adds sensors to the control system and uses algorithms to monitor and control the movement of the pallet. The initial investment cost is high and the production cost of a single product is increased, which is more troublesome for the production of small and medium-sized enterprises.

[0020] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0021] First, combine Figures 1 to 5 The tray non-return mechanism according to the embodiment of the utility model is described and is widely used in scenarios such as mechanical manufacturing.

[0022] like Figures 1 to 5 As shown, the pallet non-return mechanism of the embodiment of the utility model is used to prevent the pallet located at a processing station from returning. The processing station includes a base 1, preferably, a baffle body 2, a limit assembly 3, and a guide end 4.

[0023] Specifically, Figures 1 to 5 As shown, the baffle body 2 is arranged on the side of the base 1 close to the tray entering, and the position where the baffle body 2 is fixed to the side of the base 1 is the fixed position 21, and the fixed position 21 is not arranged at the center of gravity of the baffle body 2. The baffle body 2 can swing around the fixed position 21, and the baffle body 2 is in the flow path of the tray or away from the flow path by its own swinging, and the tray smoothly enters the base 1. By deviating from the fixed position 21 of the center of gravity, the baffle body 2 can be quickly reset, effectively preventing the reverse flow of subsequent trays, and the automatic control of the tray is realized only by the mechanical mechanism; the limit assembly 3 limits the swing of the baffle body 2 Angle, ensuring that the swing angle will not be too large, preventing the entire mechanism from running poorly, and ensuring the stability of the baffle body 2 during the swinging process; the guide end 4 is arranged on one side of the baffle body 2, and the pallet enters the processing station along the guide end 4, and the guide and the block are designed as an integrated whole, with a simple structure but ensuring the smooth blocking and flow, and the structure is simple and the effect is good; the technical solution has strong adaptability and scalability, whether it is for pallets of different specifications and weights, or for production lines with different processes and production requirements, it can meet actual needs through simple adjustments or modifications.

[0024] Preferably, if Figure 1 , 2 As shown, the barrier body 2 is a prism with a more stable structure and stronger impact resistance. The end of the barrier body 2 away from the guide end 4 is the pressing end 22. The distance from the guide end 4 to the fixed position 21 is smaller than the distance from the pressing end 22 to the fixed position 21. The eccentric fixed end ensures that when there is no tray pressing down, the pressing end 22 swings downward due to gravity, and the guide end 4 swings upward to block the tray.

[0025] Preferably, the mass density of the pressing end 22 is greater than that of the guiding end 4. Through density deviation or the provision of a counterweight, it can also be achieved that when there is no pallet pressing down, the pressing end 22 swings downward due to gravity and the guiding end 4 swings upward to block the pallet.

[0026] Preferably, if Figure 1 , 5 As shown, the guide end 4 includes a stopper 41 arranged at one end of the baffle body 2, and a slope 42 is provided on the stopper 41. After the slope 42 contacts the pallet, the guide end 4 is pressed down by the pallet, and the guide end 4 swings toward the base 1 together with the baffle body 2. After the slope 42 contacts the pallet, the pallet can be smoothly guided into the processing station. At the same time, after the guide end 4 is pressed down by the pallet, it swings toward the base 1 together with the baffle body 2, thereby ensuring the smooth flow of the pallet.

[0027] Preferably, if Figure 3 , 4 As shown, a bracket 6 is provided on one side of the base 1, and the baffle body 2 is provided on the bracket 6. The bracket 6 supports the baffle body 2, thereby increasing the stability and reliability of the structure.

[0028] Preferably, the baffle body 2 is arranged on the bracket 6 by means of a fixing member 61, the fixing member 61 is located at the fixing position 21 and is located on the outside away from the base 1, and the baffle body 2 is fixed to the bracket 6 by means of the fixing member 61, the fixing member 61 is located on the outside of the fixing position 21. This design enables the baffle body 2 to swing smoothly around the fixing position 21, and the fixing member 61 will not interfere with the swinging of the inner baffle body 2.

[0029] Preferably, if Figure 3 , 4 As shown, the limit assembly 3 includes a first limit column 31 and a second limit column 32. The first limit column 31 and the second limit column 32 are both arranged on the bracket 6 and located near the inner side of the base 1, ensuring the stability and accuracy of the partition body 2 during the swinging process and preventing the mechanism from operating poorly or malfunctioning due to excessive swinging.

[0030] Preferably, if Figure 2 , 4 As shown, when the pallet passes through the guide end 4, the guide end 4 swings to the first limit column 31, and when the pallet enters the base 1, the lower pressure end 22 swings to the second limit column 32, which respectively correspond to the angles when the partition body 2 swings to different sides. At the same time, the position can be adjusted according to the model of the pallet, etc., and it has strong adaptability.

[0031] Preferably, if Figure 5As shown, the limiting assembly 3 also includes a third limiting column 33, which is arranged on the side of the pressing end 22 away from the base 1. When the pressing end 22 swings toward the second limiting column 32, the third limiting column 33 swings toward the bracket 6, which is used to further limit the swing of the pressing end 22, thereby enhancing the safety and stability of the mechanism.

[0032] Preferably, if Figure 1 , 3 As shown, a locking piece 5 is provided on the side of the base 1 away from the baffle body 2, and a recess 51 is provided on the locking piece 5. When the pallet enters the base 1, the locking piece 5 is pushed, and the recess 51 fixes the edge of the pallet, further increasing the limitation on the position of the pallet, preventing the pallet from moving or sliding during the processing, and improving the processing accuracy and stability.

[0033] During use, when the pallet enters along the slope 42 of the guide end 4, the guide end 4 is pressed down by the pallet and swings, thereby driving the barrier body 2 to swing as a whole toward the base 1, allowing the pallet to smoothly enter the processing station. At the same time, the limit assembly 3 ensures that the swing angle of the barrier body 2 is within a reasonable range to avoid excessive swinging. After the pallet enters the base 1, the recess 51 on the locking member 5 fixes the edge of the pallet to prevent it from moving. At this time, the downward pressing end 22 is subject to gravity, causing the barrier body 2 to reset, preventing the pallet from flowing back while waiting for the next pallet. After the processing of this station is completed, the cylinder under the locking member 5 drives the lock to descend, and the pallet on the base can enter the next process. At this time, the cylinder drives the locking member 5 to reset and wait for the next pallet.

[0034] Above, refer to Figures 1 to 5 The invention describes a pallet non-return mechanism according to an embodiment of the utility model. By designing a baffle structure, the pallet can smoothly enter the processing station along the guide end, and the baffle can reliably block the backflow of the pallet, thereby ensuring the continuity and stability of the processing process. The pallet smoothly enters the base by swinging the baffle in the flow path of the pallet or away from the flow path. The baffle can quickly reset by deviating from the fixed position of the center of gravity, effectively preventing the reverse flow of the pallet, and realizing automatic control of the pallet only through the mechanical mechanism. The design of the guide end enables the pallet to easily enter the processing station without complicated operations or additional auxiliary equipment. This not only improves work efficiency, but also reduces the labor intensity of operators. The entire structure is simple, easy to maintain and very low cost, and has strong adaptability and scalability. It achieves the reduction of production interruptions and waste caused by pallet backflow without investing a lot of cost, thereby bringing higher economic benefits to the enterprise.
