Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to a three-channel automatic gate trimming, classification and palletizing device. Background Art

[0002] At present, the workstations beside injection molding machines all use an automatic gate trimming workbench to process the gates of products. The existing methods all use a one-in-one-out gate trimming method and use the manipulator configured by the injection molding machine for palletizing. However, many products are completed by the cooperation of an upper cover and a lower cover (or a left housing and a right housing), and a two-cavity mold is required. After injection molding, the injection molding manipulator needs to grab the products and move them to the gate trimming device for processing, and at the same time, classify and place different products on different blister trays. However, the manipulator configured on the current injection molding machine cannot meet the requirements of classification and placement due to travel limitations, and there is no equipment that meets the requirements on the market, which requires manual cooperation, seriously affecting production efficiency and resulting in high labor costs. Therefore, a set of equipment for automatic gate trimming and automatic classification and palletizing is needed to improve work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defect that the prior art cannot perform gate trimming and automatic classification and palletizing at the same time, and provide a three-channel automatic gate trimming and classification palletizing device that can automatically trim the gate and automatically classify and palletize, improving production efficiency and reducing labor costs.

[0004] To achieve the above object, the solution of the present invention is:

[0005] A three-channel automatic gate trimming and classification palletizing device, which includes a frame, a palletizing moving module, a gate trimming mechanism, a first palletizing mechanism, a second palletizing mechanism and a transfer and adjustment module; the gate trimming mechanism, the first palletizing mechanism and the second palletizing mechanism are arranged side by side in front of the frame, the palletizing moving module is arranged on the frame and is located above the gate trimming mechanism, the first palletizing mechanism and the second palletizing mechanism, and the palletizing moving module can move between the gate trimming, the first palletizing mechanism and the second palletizing mechanism.

[0031] like Figure 8 As shown, the first swing plate mechanism 4 includes a second bracket 41, a discharging mechanism 42, a lifting module 43 and a positioning mechanism 44 (cooperating with Figure 1 and Figure 2 As shown), the second bracket 41 is arranged side by side with the first bracket 31, and the discharge mechanism 42 is arranged on the second bracket 41. The structure of the discharge mechanism 42 is the same as that of the feed mechanism 32 and will not be described in detail. The lifting module 43 is arranged on the second bracket 41 corresponding to the rear end of the discharge mechanism 42. The structure of the lifting module 43 is the same as that of the lifting mechanism 33 and will not be described in detail. The top of the second bracket 41 is provided with the positioning mechanism 44, and the positioning mechanism 44 includes a horizontal transverse adjustment cylinder 441 and a horizontal longitudinal adjustment cylinder 442. The horizontal transverse adjustment cylinder 441 is fixedly arranged at the front end of the second frame 41, and the horizontal longitudinal adjustment cylinder 442 is arranged on one of the left and right ends of the second frame 41, so as to fix the blister plate A, so as to facilitate the plate moving module 2 to place the product on the blister plate A.

[0032] See also Figure 8The second tray arranging mechanism 5 is arranged side by side with the first tray arranging mechanism 4, and the structure of the second tray arranging mechanism 5 is the same as that of the first tray arranging mechanism 4, so it will not be described in detail.

[0033] As Figure 9 shown, the transfer and adjustment module 6 includes a horizontal guide rail 61, a horizontal slider 62, a guide rail mounting plate 63, a connecting arm 64, a suction cup cylinder 65 and a plastic suction tray suction cup 66. The guide rail mounting plates 63 are arranged at intervals on the horizontal guide rail 62. There are at least two guide rail mounting plates 63, and multiple guide rail mounting plates 63 are horizontally and transversely mounted on the inner sides of the first bracket of the shearing and milling gate mechanism 3, the second bracket of the first tray arranging mechanism 4 and the second bracket of the second tray arranging mechanism 5.

The push rod of the suction cup cylinder 65 is connected to the plastic suction tray suction cup 66.

[0034] When the present invention is in use, empty plastic suction trays are placed on the conveyor belt 332 of the feeding mechanism 32 of the shearing and milling gate mechanism 3. The injection molding machine injects two kinds of products at the same time (such as the upper cover and the lower cover). If the size differences of the products are small, the same plastic suction trays can be used for arranging the two kinds of products. If the products have different sizes and different specifications of plastic suction trays are needed, the two different plastic suction trays are placed vertically and staggered on the feeding mechanism 32. The plastic suction trays to be arranged are placed on the first tray arranging mechanism 4. The plastic suction trays to be arranged are sucked from the feeding mechanism 32 by the transfer and adjustment module 6 and then moved to the lifting plate of the lifting module 43 at a preset position. The plastic suction trays to be arranged are placed on the third tray arranging mechanism 5. The plastic suction trays on the third tray arranging mechanism 5 are also sucked from the feeding mechanism 32 by the transfer and adjustment module 6 and then moved to the lifting plate of the lifting module of the third tray arranging mechanism 5. The second lifting modules 43 of the first tray arranging mechanism 4 and the second tray arranging mechanism 5 respectively lift their corresponding plastic suction trays upwards to the positions of the corresponding positioning mechanisms 44. The horizontal transverse cylinder 441 and the horizontal longitudinal cylinder 442 of the positioning mechanism 44 are respectively pushed out to fix the plastic suction trays at the preset positions and prepare to receive the products. After the injection molding machine completes the injection of the products, the manipulator of the injection molding machine sequentially places the two products on the two positioning parts 342 of the shearing and milling gate mechanism 3, and the gate is sheared and milled by the milling cutter 343. After the gate treatment is completed, the tray arranging and moving module 2 moves the two different products to the corresponding first tray arranging mechanism 4 or the second tray arranging mechanism 5. When the plastic suction tray A is full of products, the lifting plate of the second lifting module 43 moves downwards, and the empty plastic suction tray on the shearing and milling gate mechanism 3 is stacked on the plastic suction tray already full of products through the transfer and adjustment module 6. This is repeated, and finally the whole stack of plastic suction trays full of products is conveyed out from the conveyor belts of the first tray arranging mechanism and the second tray arranging mechanism and docked with the AGV to complete the transfer of the products.

[0035] The present invention provides a processing station with three channels. In addition to performing operations such as trimming and milling the gates of products, the first processing station can also place empty plastic trays. Through a transfer and adjustment module, the empty plastic trays can be moved to the first tray arranging mechanism and the second tray arranging mechanism, thereby completing the automatic feeding and discharging of products. The second processing station is used for arranging one type of product, and the third processing station is used for arranging another type of product. The present invention can be placed beside an injection molding machine, facilitating the automatic trimming and milling of gates and automatic sorting and tray arranging of products in an injection molding machine with two cavities per mold.

[0036] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present invention.
