Description

TECHNICAL FIELD

[0001] The utility model relates to material transfer technical field, especially relates to a conveying steering correction device. BACKGROUND

[0002] When the consumer opens the commodity package, the front and back placement of the commodity should be consistent with the front and back of the packaging box, which not only helps to improve the identification, but also is convenient for the customer to scan the code after opening the package. However, during the transfer process of the packaging box before packaging, it is inevitable that the placement direction of individual packaging boxes is opposite to the direction required by the packaging. When the commodity reaches the packaging position, the operator needs to manually adjust the placement direction of the packaging box before starting the packaging. If the packaging box is large in size, not only is it laborious to manually move, but also it may cause damage to the packaging box, which not only reduces the production efficiency, but also increases the production cost.

The protruding end of the locking bolt 72 is screwed into the threaded hole, and the inner side wall of the nut of the locking bolt 72 abuts against the outer side wall of the guide sleeve 7, so as to adjust and position the connection between the support frame 10 and the guide sleeve 7.

[0040] The working principle of this utility model is as follows:

[0041] like Figures 1 to 4 As shown, a QR code is provided on one side of the material box. In this embodiment, the monitoring device includes barcode scanners located at four positions: front, back, left, and right of the feeding end of the conveying mechanism 1. Based on the barcode scanning response of the barcode scanner at the corresponding position, the placement status of the material box is automatically identified, and the placement status of the material box is sent to the PLC controller in the form of a digital signal. The PLC controller then sends corresponding operation commands to the limit mechanism 4, the lifting component 3, and the steering mechanism 5 based on the received digital signal, so as to realize the automatic linkage operation between the various mechanisms and components. That is, the direction of the material box and the required rotation angle are determined by scanning the barcode.

[0042] At the same time, the position sensor 43 has a counting function when receiving the cartridge arrival signal, and the PLC controller records the scanning order of the code scanner, and then, when the reversed cartridge is identified by the code scanner, the position sensor 43 detects the cartridge in place in sequence, and the position sensor 43 sends the corresponding counting value to the PLC controller, and when the counting value matches the sequence, the PLC controller sends a corresponding instruction to the limiting mechanism 4 to stop the reversed cartridge at the position of the turning mechanism 5; in this way, the placement direction of the error cartridge is corrected in time, and the normal placement of the cartridge is not affected.

[0043] In use, first, the PLC controller starts the driving motor 12 to drive the conveyor belt 14, the rotating wheel 13, the rotating roller 11 and the drum 110 to rotate synchronously, and then places the cartridge on the drum 110 to drive the cartridge to move on the support frame 10. When the monitor 2 identifies that the cartridge is reversed, the digital signal generated by the identification is sent to the PLC controller, and the position sensor 43 detects the cartridge at the preset time point and immediately sends a signal to the PLC controller, and then the PLC controller sends an instruction to the second air cylinder 42 to drive the baffle 41 to vertically extend the second gap part 112 and protrude out of the upper surface of the drum 110 to stop the reversed cartridge.

[0044] Subsequently, as shown in Figures 5 to 7 the PLC controller starts the first air cylinder 31 to drive the supporting plate 33, the mounting disc sleeve 50 and the bracket 6 to move upward synchronously, and the bracket 6 drives the cartridge to rise and separate from the upper surface of the drum 110, and then the PLC controller closes the first air cylinder 31 and simultaneously starts the second air cylinder 42 to drive the baffle 41 to move downward.

[0045] Then, the PLC controller starts the servo motor 51 to drive the meshing tooth disc 54 to rotate synchronously through the transmission teeth 55, and since the tooth disc 54 is sleeved on the roller bearing 53, and the flange plate 56 is connected to the upper end surface of the roller bearing 53, the flange plate 56, the bottom plate 57 connected to the flange plate 56 and the bracket 6 connected to the bottom plate 57 are driven to rotate synchronously; after the horizontal rotation is in place, the PLC controller closes the servo motor 51 and then starts the second air cylinder 42 to drive the bracket 6 to move downward, and when the cartridge contacts the drum 110, the normal transfer state is restored.

[0046] Among them, the material box is detected by the position sensor 43 and moves to abut against the baffle 41, and there is a time interval, which should be combined with the spacing between the adjacent two material boxes, so as to effectively preset the starting time point of the second cylinder 42 on the PLC controller, so as to effectively prevent the use interference with the normally placed material box; Similarly, the opening and closing switching interval between the first cylinder 31 and the second cylinder 42 also needs to be verified and preset, so that the baffle 41 does not constitute use interference when turning, Finally, the whole turning error correction period is set, and the moving interval period between two adjacent material boxes also needs to be met, so as to prevent the lifted material box from being knocked and falling or the exposed bracket 6 from scratching the material box.

[0047] Before use, in order to facilitate the adjustment of the height of the conveying position, a guide sleeve 7 is sleeved on the outer side of the lower end of the support frame 10, a locking bolt 72 is threaded at the strip-shaped groove 71, the threaded end of the locking bolt 72 is screwed with the threaded hole on the support frame 10, and the inner side wall of the nut of the locking bolt 72 abuts against the outer side wall of the guide sleeve 7, so that the support frame 10 and the guide sleeve 7 are fixedly connected after being positioned by lifting adjustment.

[0048] In this embodiment, the PLC controller is not involved in program adjustment, and can be directly used by adaptively presetting relevant parameters; Similarly, the code scanner used is also prior art, and the PLC controller only needs to judge which direction of the code scanner signal is received and then issue a corresponding instruction, and the connection form and specific working principle are not described here.
