DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below. Figure 1 and Figure 2 , an embodiment of the present invention provides an automatic material receiving machine, including a product transfer mechanism 100 and an empty tray receiving mechanism 200 arranged side by side. The product transfer mechanism 100 includes a product transfer platform 110 and a product lifting mechanism 120. The product transfer platform 110 is used to move the processed products from the production line of the previous process to the production line of the next process. The product transfer mechanism 100 can be lifted and lowered under the drive of the product lifting mechanism 120. The empty tray receiving mechanism 200 includes an empty tray receiving mechanism 210, an empty tray stacking platform 220 and a receiving lifting mechanism 230. The empty tray receiving mechanism 210 can be lifted and lowered under the drive of the receiving lifting mechanism 230. The empty tray receiving mechanism 210 is used to recover the empty tray from the previous device and place the empty tray on the empty tray stacking platform 220 for stacking.

[0026] The automatic material receiving machine can transfer products through the product transfer mechanism 100, and recycle empty trays, i.e. material trays, through the empty tray receiving mechanism 200, thereby avoiding the need to connect automatic material receiving equipment for products and material trays to the production line, shortening the length of the production line and reducing the floor space of the production line. In addition, since the product transfer platform 110 and the empty tray receiving mechanism 210 can be lifted and lowered under the drive of the product lifting mechanism 120 and the receiving lifting mechanism 230, respectively, it is possible to recycle products or trays on multiple conveying mechanisms arranged vertically, thereby improving the circulation efficiency of products and trays, thereby improving the production efficiency of the production line, and avoiding the phenomenon that products or trays are piled up on a conveying mechanism due to the low production efficiency of a single device.

[0027] In some embodiments, in order to further improve the return efficiency of the trays, the automatic material receiving machine also includes an AGV docking mechanism 300, which is arranged on one side of the empty tray receiving mechanism 200. The AGV docking mechanism 300 is used to move the tray stack on the empty tray stacking platform 220 to the AGV robot, so as to facilitate the AGV robot to send the recycled trays to the loading equipment for reloading, thereby improving the efficiency of the empty trays flowing back into the production line for reuse.

[0028] In some embodiments, in order to further improve the recycling efficiency of the empty tray of the automatic material receiving machine, the empty tray receiving mechanism 200 also includes a stacking and lifting mechanism 240. The empty tray stacking platform 220 can be lifted and lowered under the drive of the stacking and lifting mechanism 240, so that when the empty tray receiving mechanism 210 is lifted to receive the tray from the higher conveying mechanism, the empty tray stacking platform 220 can be lifted synchronously, thereby shortening the distance that the empty tray receiving mechanism 210 moves when moving the received tray to the empty tray stacking platform 220, freeing the empty tray receiving mechanism 210 as soon as possible to receive and recycle other empty trays, thereby improving the recycling efficiency of the empty trays.

[0029] It is understandable that the product transfer platform 110 can use a conveyor belt, a roller belt or a conveyor track to achieve product transfer. Since the empty tray receiving mechanism 210 needs to move the received tray to the empty tray stacking platform 220 for stacking, the empty tray receiving mechanism 210 can only use a conveyor track to receive the tray. After receiving the tray, the conveyor track needs to be opened so that the tray on the conveyor track can fall onto the empty tray stacking platform 220.

[0030] Reference Figure 3In this embodiment, the product transfer platform 110 includes a transfer mechanism bracket 111, a pair of first conveying rails 112 and a first spacing adjustment mechanism 113. The transfer mechanism bracket 111 is connected to the product lifting mechanism 120, and the two first conveying rails 112 are slidably arranged on the transfer mechanism bracket 111 through the first spacing adjustment mechanism 113. The first spacing adjustment mechanism 113 is used to adjust the spacing between the two first conveying rails 112 to adapt to products of different widths. The feeding side and the discharging side of the transfer mechanism bracket 111 are both provided with a blocking mechanism 114, which is used to block the product when the product transfer platform 110 is lifted or lowered to prevent the product from sliding off the product transfer platform 110. The transfer mechanism bracket 111 or the first conveying rail 112 is provided with a first in-and-out plate sensor 115 of the product transfer platform 110 for detecting whether there are products entering or exiting.

[0031] Reference Figure 4 and Figure 5 The empty tray receiving mechanism 210 includes a receiving mechanism bracket 211, a pair of second conveying rails 212, a second spacing adjustment mechanism 213 and a tray grabbing mechanism 214. The receiving mechanism bracket 211 is connected to the receiving lifting mechanism 230, and the two second conveying rails 212 are slidably arranged on the receiving mechanism bracket 211 through the second spacing adjustment mechanism 213. The second spacing adjustment mechanism 213 is used to adjust the spacing between the two second conveying rails 212 to accommodate trays of different widths. A second in-and-out plate sensor 216 for detecting whether a tray enters or exits the empty tray receiving mechanism is provided on the receiving mechanism bracket 211 or the second conveying rail 212. The tray grabbing mechanism 214 is arranged above the receiving mechanism bracket 211, and the tray grabbing mechanism 214 is used to grab the tray on the second conveying rail 212 and lift it to a certain height. A pair of opening drive mechanisms 215 are slidably arranged on the second spacing adjustment mechanism 213. The two opening drive mechanisms 215 are respectively arranged on the outer sides of the two second conveying rails 212. The opening drive mechanisms 215 are used to drive the second conveying rails 212 to move in the width direction of the Tray, so that the spacing between the two second conveying rails 212 is slightly wider than the width of the Tray, so that the Tray grasping mechanism 214 can grasp the Tray through the space between the two second conveying rails 212 and be placed on the empty Tray stacking platform 220.

[0032] It is understandable that the first conveying track 112 and the second conveying track 212 can use a synchronous belt or a conveying chain to receive and transport the product or tray. In this embodiment, the structures of the first conveying track 112 and the second conveying track 212 are similar. Figure 3Taking the first conveying track 112 as an example, the first conveying track 112 includes a conveying mounting plate 1121, a synchronous belt mechanism 1122 and a synchronous belt driving motor 1124. The synchronous belt mechanism 1122 is arranged on the inner side of the conveying mounting plate 1121. The synchronous belt mechanism 1122 includes a synchronous belt and a plurality of synchronous wheels. The plurality of synchronous wheels are rotatably arranged on the inner side of the conveying mounting plate 1121. The synchronous belt is wound around the plurality of synchronous wheels. The plurality of synchronous wheels make the synchronous belt circulate along the conveying direction of the product. The synchronous belt driving motor 1124 is arranged on the outer side of the conveying mounting plate 1121. The output shaft of the synchronous belt driving motor 1124 passes through the conveying mounting plate 1121 and is connected to the corresponding active synchronous wheel shaft in the synchronous belt mechanism 1122, thereby realizing the driving of the synchronous belt. A synchronous belt supporting beam 1123 is arranged below the upper side of the synchronous belt. The synchronous belt supporting beam 1123 is arranged along the conveying direction of the product. The synchronous belt supporting beam 1123 is used to support the synchronous belt to prevent the synchronous belt from collapsing under the action of the gravity of the product.

[0033] It is understandable that the first spacing adjustment mechanism 113 and the second spacing adjustment mechanism 213 can be implemented by means of a slide rail or the like. In this embodiment, the structures of the first spacing adjustment mechanism 113 and the second spacing adjustment mechanism 213 are similar. Figure 3 Taking the first spacing adjustment mechanism 113 as an example, the first spacing adjustment mechanism 113 includes two adjustment guide columns 1131 and two pairs of adjustment sliders 1132. The adjustment sliders 1132 are provided with guide grooves for the adjustment guide columns 1131 to pass through. The opening of the guide grooves is provided with adjustment bolts. The free ends of the adjustment bolts are provided with adjustment handles 1133. The width of the guide grooves can be adjusted by loosening and tightening the adjustment nuts, thereby adjusting the friction between the groove wall of the guide groove and the surface of the adjustment guide columns 1131 to achieve the fixing and release of the adjustment sliders 1132. The transfer mechanism bracket 111 and the receiving mechanism bracket 211 are both frame structures. The two adjustment guide columns 1131 of the first spacing adjustment mechanism 113 are respectively arranged at the front and rear ends of the transfer mechanism bracket 111 along the width direction of the product. The two adjustment sliders 1132 in each pair of adjustment sliders 1132 are respectively arranged at the front and rear ends of the corresponding transmission mounting plate 1121. The front and rear ends of the transmission mounting plate 1121 are respectively slidably arranged on the two adjustment guide columns 1131 through the two adjustment sliders 1132. When the width between the two first conveying rails 112 needs to be adjusted, loosen the adjusting bolt by adjusting the handle 1133, unlock the sliding of the adjusting slider 1132, slide the first conveying rail 112 according to the size of the product, so that the spacing between the two first conveying rails 112 matches the width of the product, and then tighten the adjusting bolt by adjusting the bolt to lock the position of the adjusting slider 1132 again.

[0034] Reference Figure 4 and Figure 5In this embodiment, the opening drive mechanism 215 preferably uses a cylinder to drive the second conveying track 212 to move. The opening drive mechanism 215 includes an opening mechanism mounting plate 2151, an opening drive cylinder 2152 and two pairs of linear bearings 2153. The two linear bearings 2153 in each pair of linear bearings 2153 are respectively arranged on the corresponding conveying mounting plate 1121 of the second conveying track 212, and the two ends of the conveying mounting plate 1121 of the second conveying track 212 are slidably arranged on the adjustment guide column 1131 of the second spacing adjustment mechanism 213 through the linear bearings 2153. The adjustment slider 1132 of the second spacing adjustment mechanism 213 is arranged at the two ends of the two opening mechanism mounting plates 2151, and the opening mechanism mounting plates 2151 are slidably arranged on the outer side of the corresponding conveying mounting plate 1121 through the adjustment slider 1132, and the opening drive cylinder 2152 is arranged between the corresponding opening mechanism mounting plate 2151 and the conveying mounting plate 1121. When in use, with the piston of the open driving cylinder 2152 extended, the second spacing adjustment mechanism 213 is adjusted to make the spacing between the two second conveying tracks 212 match the width of the Tray. When the Tray received by the Tray needs to be placed on the empty Tray stacking platform 220, the piston of the open driving cylinder 2152 is controlled to retract, so that the spacing between the two second conveying tracks 212 can be slightly wider than the width of the Tray, which is convenient for the Tray grabbing mechanism 214 to place the grabbed Tray on the empty Tray stacking platform 220.

[0035] It is understandable that the tray grabbing mechanism 214 can grab the tray from the second conveying track 212 by clamping or sucking. Figure 5 In this embodiment, the tray grabbing mechanism 214 includes a tray suction cup and a suction cup lifting drive mechanism 2144. The tray suction cup is provided with a plurality of position-adjustable suction nozzles 2143. The suction cup lifting drive mechanism 2144 is provided on the receiving mechanism bracket 211. The tray suction cup is provided above the receiving mechanism bracket 211. The tray suction cup can be lifted and lowered under the drive of the suction cup lifting drive mechanism 2144. The tray suction cup includes a suction cup bracket 2141 and a suction cup mounting plate 2142. The suction cup bracket 2141 is straddled on the receiving mechanism bracket 211 along the width of the tray. The suction cup bracket 2141 is provided with a long strip hole. The suction cup mounting plate 2142 is installed on the suction cup bracket 2141 by bolts passing through the long strip hole, so as to adjust the spacing and number between the suction cup mounting plates 2142. The suction nozzle 2143 is detachably mounted on the lower surface of the suction cup mounting plate 2142 by magnetic attraction, so as to adjust the position of the suction nozzle 2143 to adapt to the size of trays of different sizes. The suction cup lifting drive mechanism 2144 preferably uses a cylinder to drive the lifting of the tray suction cup.

[0036] Reference Figure 1 and Figure 2 In this embodiment, the empty tray stacking platform 220 is disposed directly below the empty tray receiving mechanism 200. Figure 6 The empty tray stacking platform 220 includes a stacking platform support 221 and at least two ribs 222, the two ribs 222 are vertically arranged on the stacking platform support 221, and the stacking platform support 221 is connected to the stacking lifting mechanism 240. A support plate 2221 for supporting the tray stack is arranged at the bottom of the rib 222, and the rib 222 supports the edge of the bottommost tray through the support plate 2221 to realize the bearing of the tray stack, and at the same time, the vertical rib 222 can block the side of the tray stack to prevent the tray stack from tipping over.

[0037] Reference Figure 6 In this embodiment, a stacking platform lifting drive mechanism 223 is provided on the stacking platform bracket 221. The stacking platform lifting drive mechanism 223 is used to drive the sidewall 222 to perform lifting movement within a certain range, so that the sidewall 222 extends into the empty tray receiving mechanism 210 to receive the tray, and the tray stack is placed on the AGV docking mechanism 300. The stacking platform bracket 221 includes a horizontal plate 2211 and a pair of side plates 2212. The horizontal plate 2211 is connected to the stacking lifting mechanism 240. The two side plates 2212 are vertically arranged at both ends of the horizontal plate 2211, and form a U-shaped frame with the horizontal plate 2211, so that the tray stack is placed on the AGV docking mechanism 300. Adjustment slots 22111 are provided at both ends of the horizontal plate 2211. The side plates 2212 are slidably arranged in the adjustment slots 22111, so as to adjust the spacing between the sidewalls 222 on both sides to adapt to the lengths of different trays. A scale 22212 is provided above the slide 22111, and a step is provided to facilitate the adjustment of the spacing between the side guards 222 on both sides. Two side guards 222 are provided on each side plate 2212, and the side guards 222 are provided on the side plate 2212 through the stacking platform lifting drive mechanism 223. Figure 6 In this embodiment, the stacking platform lifting drive mechanism 223 preferably uses a cylinder to drive the lifting of the side guard 222. The stacking platform lifting drive mechanism 223 includes a movable bracket, which is vertically slidably set on the corresponding side plate 2212. The movable bracket is provided with a slide groove along the width direction of the Tray. The outer side guard 222 is slidably set in the slide groove of the movable bracket by adjusting the slide plate 2222, so as to adjust the distance between the two side guards 222 on the same side to adapt to the width of Trays of different widths.

[0038] Reference Figure 4In this embodiment, a plurality of tray stack detection sensors 217 are provided at the bottom of the receiving mechanism. The tray stack detection sensors 217 are used to detect whether the tray stack is inserted into the empty tray receiving mechanism 210, so as to avoid the second conveying track 212 contracting when the upper end of the tray stack extends into the empty tray receiving mechanism 210, resulting in a collision between the second conveying track 212 and the retaining edge 222 or the tray stack. It is understandable that the first in-and-out plate sensor 115, the second in-and-out plate sensor 216 and the tray stack detection sensor 217 are preferably photoelectric sensors, and the blocking mechanism 114 is preferably a blocking cylinder. Figure 2 and Figure 6 The product lifting mechanism 120, the receiving lifting mechanism 230 and the stacking lifting mechanism 240 can be composed of a lead screw pair and a slide rail, wherein the slide rails of the receiving lifting mechanism 230 and the stacking lifting mechanism 240 can be shared.

[0039] Reference Figure 1 and Figure 7 The AGV docking mechanism 300 includes a docking channel 310 and a docking conveying mechanism 320. The docking conveying mechanism 320 is arranged in the docking channel 310. The entrance of the docking channel 310 is arranged on one side of the empty Tray receiving mechanism 200. The exit of the docking channel 310 is used for docking with the AGV robot. The docking conveying mechanism 320 transports the Tray disk stack on the empty Tray receiving mechanism 200 through the docking channel 310 and transports it to the bearing platform of the AGV robot. It can be understood that the docking conveying mechanism 320 can adopt a roller belt or a conveyor belt. In this embodiment, the docking conveying mechanism 320 adopts a conveyor belt. Guide baffles 321 are arranged on both sides of the docking conveying mechanism 320. The guide baffles 321 are arranged along the transporting direction of the docking conveying mechanism 320 to prevent the Tray disk stack from tilting and collapsing during the movement.

[0040] In the automatic material receiving machine of the embodiment of the present invention, the product transfer mechanism 100 is driven by the product lifting mechanism 120 to be flush with the conveying mechanism to which the product needs to be transferred, receives the product, and is driven by the product lifting mechanism 120 to move it to the conveying mechanism with fewer products in the next production line to realize product scheduling and avoid blockage caused by too many products on the conveying mechanism. After the empty tray receiving mechanism 210 receives the tray, the tray suction cup grabs the tray on the second conveying track 212, and then opens the driving mechanism 215 to drive the second conveying track 212 to open. The empty tray receiving mechanism 210 and the empty tray stacking platform 220 move toward each other under the drive of the receiving lifting mechanism 230 and the stacking lifting mechanism 240 respectively, so that the top of the tray stack on the empty tray stacking platform 220 extends into the empty tray receiving mechanism 210, and the tray suction cup descends and releases its grip on the tray, so that the tray falls on the tray stack, and then the empty tray receiving mechanism 210 is separated from the empty tray stacking platform 220, and the driving mechanism 215 is opened to drive the second conveying track 212 to recover. When the trays on the empty tray receiving mechanism 210 are full, the automatic material receiving machine calls the AGV robot. After the AGV robot docks with the exit of the docking channel 310, the empty tray stacking platform 220 lowers the tray stack to the docking conveying mechanism 320. The docking conveying mechanism 320 transports the tray stack to the AGV robot, thereby improving the return efficiency of the trays.
