Description

Technical Field

[0001] The utility model relates to a material pushing device, in particular to a material pushing device with high compatibility for a material inlet of a cartoning machine. Background Art

[0002] In order to improve the overall production efficiency and automation of production, robots, material pushing devices, etc. are usually used in the packaging process to achieve automatic packaging instead of traditional manual packaging. For smaller products, material pushing devices are more suitable than robots, and have higher operating efficiency and accuracy. Existing material pushing devices are commonly used in products with a single structure. Chinese patent CN212639088U discloses a sorting mechanism that can sort and arrange multiple bottled cosmetics at a time, replacing manual sorting. The sorting efficiency is high and it is convenient for the subsequent processing of bottled cosmetics. However, its disadvantage is that it cannot be applied to products of different sizes and large spans, such as gears.

[0003] Gear products need to be pushed into cartons for packaging. When the size of the product is within a certain range, a carton of fixed size can be used for compatibility. However, when the size span of the product is larger, cartons of different sizes need to be replaced. The discharge port of the carton facing the pushing device is open. In order to fix the position of the carton, one side of the carton is generally fixed at all times in the prior art, which is the fixed side, and the side opposite to the fixed side is the movable side. In order to ensure that the parts can enter the carton accurately, it is necessary to ensure that the movable side of the carton and the side corresponding to the parts are on the same reference plane. However, when replacing cartons of different sizes, the position of the movable side of the carton changes, so the position of the pushed parts needs to be adjusted synchronously.

[0046] like Figure 1 , Figure 3 As shown, the third driving mechanism includes a rodless cylinder 403 and a cylinder auxiliary guide rail 404 installed between two side plates 402. The rodless cylinder 403 is connected to the lower end surface of the bottom plate 401, and the cylinder auxiliary guide rail 404 is located below the rodless cylinder 403, and the cylinder auxiliary guide rail 404 is arranged perpendicular to the conveying direction of the conveyor belt 102; a slider 405 is sleeved on the cylinder auxiliary guide rail 404, and a pushing component is connected below the slider 405. Magnetic sensors are also installed at both ends of the rodless cylinder 403 to detect the moving position of the slider 405. When the slider 405 is not pushed into place or reset to the starting position, the magnetic sensor transmits a signal to the control system, and the control system notifies the rodless cylinder 403 to drive the slider 405 to move.

[0047] The push assembly includes a push arm 406 vertically connected to the bottom of the slider 405, and a push plate 407 vertically connected to the lower end of the push arm 406. The central axis of the push plate 407 along the pushing direction is used to coincide with the central axis of the paper box 5. A movement gap is left between the bottom of the push plate 407 and the conveyor belt 102 or the discharge channel 103. In this embodiment, the movement gap is 5-10mm. A push head fixing block 408 is vertically connected to one end of the push plate 407 close to the discharge channel 103, which is used to contact the product; a second reinforcement plate 409 is provided at the connection between the other end of the push plate 407 and the push arm 406.

[0048] The rodless cylinder 403, the position sensor and the magnetic sensor are connected to an external control system. The control system is used to receive the feedback signals from the position sensor and the magnetic sensor, and control the rodless cylinder 403 according to the feedback signals. A scale is also provided on the push mechanism and the reference mechanism, and the reference plate 204 and the push arm 406 can be adjusted to the corresponding scale position for parts of different sizes.

[0049] Working process: According to the size of the product to be packaged, place a paper box 5 of the corresponding size. The A side 51 of the paper box 5 is fixed to play a positioning role. Adjust the position of the reference plate 204 and the push assembly. Turn the first driving member 207 to adjust the reference plate 204 to the scale position corresponding to the current product, so that the reference plate 204 is flush with the B side 52 of the paper box 5. Turn the second driving member 308 to move the push assembly left and right along the cylinder guide rod 305, adjust the push arm 406 to the scale position corresponding to the current product, and align the push assembly with the position of the current product. The product to be packaged enters the conveyor belt 102 from the feed port. Before it is transferred to the reference plate 204, the position sensor senses the product and transmits the information to the external control system. The control system controls the rodless cylinder 403 to drive, so that the slider 405 drives the push arm 406 to move. The push head fixing block 408 of the push arm 406 contacts the product to be packaged, and the slider 405 moves along the cylinder guide rod 305 to push the product to be packaged into the paper box 5 along the discharge channel 103 .

[0050] like Figure 2 As shown, when the production line replaces a product with a larger size span, the paper box 5 of the corresponding size is replaced synchronously. The A side 51 of the paper box 5 always remains flush with one side of the discharge channel 103, and the B side 52 of the paper box 5 changes position as the size of the paper box 5 changes. Therefore, it is necessary to ensure that the side of the product to be packaged close to the reference plate 204 and the B side 52 of the paper box 5 are located on the same reference plane. The reference plate 204 and the rodless cylinder 403 can be adjusted to the scale position corresponding to the product produced after the replacement by the first drive member 207 and the second drive member 308. If the small-sized parts are replaced with large-sized parts, the reference plate 204 and the rodless cylinder 403 are moved to the side where the reference fixing plate 203 is located, so that a quick production change can be achieved.
