Description

Technical Field

[0001] The present application relates to an automated production line, and more particularly to an automatic sorting and unloading device. Background Art

[0002] Unloading materials without stopping is a criterion for judging the degree of automation of equipment in automated production. In some equipment, the automated sorting step is usually carried out simultaneously with the unloading step. Due to the mismatch between the sorting speed and the unloading speed, it is inevitable that the mechanism responsible for sorting or unloading will be in a standby waiting state.

[0003] This is especially reflected in some unloading equipment with storage trays. Materials need to be sorted and classified and placed in different storage trays. Therefore, the storage trays are constantly replaced, resulting in low efficiency in replacing storage trays between multiple sorting stations. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] refer to Figures 1 to 6 In one embodiment of the present application, an automatic sorting and unloading device is disclosed, which is used for sorting and unloading products that have been marked as qualified products or defective products, including a frame 1, on which a first silo 2 for placing qualified products and a second silo 3 for placing defective products are provided, and also includes: a product conveyor line 4 for transmitting marked products, a first sorting robot arm 5 for transporting marked qualified products, a second sorting robot arm 6 for transporting marked defective products, and a tray transmission mechanism 7 for transmitting a storage tray 8.

[0035] Among them, the transmission storage tray 7 has a first lifting platform 71 corresponding to the first material bin 2, a second lifting platform 72 corresponding to the second material bin 3, a third lifting platform 73, and a material transfer platform 74. The material transfer platform 74 is located above the first lifting platform 71, the second lifting platform 72, and the third lifting platform 73, and is used for transferring the storage tray.

[0036] Furthermore, the first sorting robot arm 5 and the second sorting robot arm 6 are arranged upstream and downstream along the transmission direction of the product conveyor line 4, and the two work independently without interfering with each other, thereby improving the sorting efficiency.

[0037] In the present application, the material transfer platform is responsible for transferring the storage trays between the first lifting platform in the first material bin and the second lifting platform in the second material bin, thereby solving the problem of replacing storage trays between multiple workstations; at the same time, a first sorting robot arm and a second sorting robot arm are provided to transport qualified products or defective products respectively, and the first sorting robot arm and the second sorting robot arm complement each other. When one of the first material bin and the second material bin is in the process of replacing the storage tray, it will not affect the normal operation of the other, thereby improving the sorting efficiency.

[0038] For further reference, Figure 4 and Figure 5 The first lifting platform 71 includes a clamping device 711 and a lifting device 712 . The clamping device 711 is used to clamp the material storage tray 8 and moves synchronously with the lifting device 712 .

[0039] Among them, Figure 5As shown, the clamping device 711 is located on both sides of the storage tray 8, and is retracted inward to cooperate with the bottom of the storage tray 8 to play a supporting role. When the lifting device 712 moves upward or downward, the clamping device 711 drives the support to move synchronously with the storage tray 8 above it.

[0040] Furthermore, the first lifting platform 71 also includes a fixing device 713 and a feeding drawer 714 . The fixing device 713 is located at the upper limit of the movement of the lifting device 712 , and the feeding drawer 714 is located at the lower limit of the movement of the lifting device 712 .

[0041] Among them, Figure 4 As shown, there are at least three fixing devices 713, which are used to push the sides of the storage tray 8 from three directions respectively, so as to fix the storage tray 8, so that the storage tray 8 can remain in the current position to carry the materials transported by the first sorting robot arm 5.

[0042] Furthermore, the first lifting platform 71, the second lifting platform 72, and the third lifting platform 73 have the same structure. The feeding drawer 714 can be used to carry the storage tray 8. When the first lifting platform 71, the second lifting platform 72, and the third lifting platform 73 are fully loaded or empty, the feeding drawer 714 can be pulled out to perform material replenishment or unloading operations.

[0043] For further reference, Figure 6 The material transfer platform 74 includes a grabbing device 741 and a pair of sliding frames 744. The two opposite ends of the grabbing device 741 are respectively slidably connected to the sliding frames 744. The sliding frames 744 are provided with a driving motor 745 for driving the grabbing device to move. In addition, at least four groups of supporting hooks 742 are provided on the grabbing device 741. The supporting hooks 742 are L-shaped, one end of which is connected to the cylinder 743 and is driven by the cylinder 743 to move closer to or away from the storage tray 8, and the other end of which acts on the lower surface of the storage tray 8. The four groups of supporting hooks 742 are respectively provided corresponding to the four corners of the storage tray 8.

[0044] Furthermore, in order to optimize the material transfer platform 74, when transferring the material storage tray 8 to one of the first lifting platform 71 or the second lifting platform 72, the other one does not affect normal operation. The grabbing device 741 moves along a straight line on the sliding frame 744, the first lifting platform 71 is located on one side of the third lifting platform 73, and the second lifting platform 72 is located on the other side of the third lifting platform 72.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0046] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
