Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to an automatic material receiving machine. Background Art

[0002] With the development of science and technology, the degree of automation in factories is getting higher and higher. Most automatic production lines use automatic material collection equipment installed at the end of the production line to automatically collect the finished products, so as to reduce the human resource costs of the factory workshop and improve the production efficiency of the workshop. However, in the actual production process, some production materials need to be placed in trays. The existing automatic material collection equipment can often only carry out product recycling and circulation, and cannot take into account the recycling of trays, and cannot be connected to AGV equipment, resulting in the need to add a variety of different material collection equipment after the production line, which greatly increases the floor space of the production line. At the same time, in some production lines, due to process requirements or efficiency requirements, there are often multiple side-by-side conveying mechanisms, and the existing automatic material collection equipment can often only collect products or trays from fixed positions, and cannot adapt to the automatic material collection of automated equipment with multiple conveying mechanisms.

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 empty trays from the previous device and place the empty trays on the empty tray stacking platform 220 for stacking.

[0026] This automatic material receiving machine can transfer products through the product transfer mechanism 100 while recovering empty trays, i.e., material trays, through the empty tray receiving mechanism 200, thereby avoiding the need for automatic material receiving equipment for products and material trays to be connected to the back of 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 driven by the product lifting mechanism 120 and the receiving lifting mechanism 230 to perform lifting movements, respectively, it is possible to recover products or trays on multiple conveyor mechanisms arranged vertically, thereby improving the flow efficiency of products and trays, thereby improving the production efficiency of the production line, and avoiding the phenomenon of products or trays being piled up on a conveyor 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 tray, the automatic material receiving machine also includes an AGV docking mechanism 300. The AGV docking mechanism 300 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 tray to the loading equipment for re-loading, thereby improving the efficiency of the empty tray flowing back into the production line for reuse.

[0028] In some embodiments, in order to further improve the recycling efficiency of the empty trays 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 trays 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 trays to the empty tray stacking platform 220, freeing up 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 understood that the product transfer platform 110 can utilize a conveyor belt, roller belt, or conveyor track to transfer products. Since the empty tray receiving mechanism 210 needs to move received trays to the empty tray stacking platform 220 for stacking, it can only receive trays using a conveyor track. After receiving a tray, the conveyor track must be opened to allow the tray on the conveyor track to 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 raised or lowered to prevent the product from slipping off the product transfer platform 110. A first in-and-out plate sensor 115 of the product transfer platform 110 for detecting whether there are products entering or exiting is provided on the transfer mechanism bracket 111 or the first conveying rail 112.

[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 set 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 is provided on the receiving mechanism bracket 211 or the second conveying rail 212 for detecting whether a tray enters or exits the empty tray receiving mechanism. The tray grabbing mechanism 214 is provided 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 slidingly arranged on the second spacing adjustment mechanism 213. The two opening drive mechanisms 215 are respectively arranged on the outside of the two second conveying rails 212. The opening drive mechanism 215 is 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 grabbing mechanism 214 can pass through the space between the two second conveying rails 212 and be placed on the empty tray stacking platform 220.

[0032] It is understood 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 conveyor track 112 as an example, it includes a conveyor mounting plate 1121, a synchronous belt mechanism 1122, and a synchronous belt drive motor 1124. The synchronous belt mechanism 1122 is located inside the conveyor mounting plate 1121 and comprises a synchronous belt and multiple synchronous pulleys. The synchronous pulleys are rotatably mounted inside the conveyor mounting plate 1121, around which the synchronous belt is wound, causing the synchronous belt to circulate along the product conveying direction. The synchronous belt drive motor 1124 is located outside the conveyor mounting plate 1121. The output shaft of the synchronous belt drive motor 1124 passes through the conveyor mounting plate 1121 and connects to the corresponding active synchronous pulley shaft in the synchronous belt mechanism 1122, thereby driving the synchronous belt. A synchronous belt support beam 1123 is located below the upper side of the synchronous belt. The synchronous belt support beam 1123 is positioned along the product conveying direction and supports the synchronous belt to prevent it from collapsing under the weight 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 slide rails 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 comprises two adjustment guide posts 1131 and two pairs of adjustment sliders 1132. The adjustment sliders 1132 are provided with guide slots through which the adjustment guide posts 1131 pass. Adjustment bolts are located at the openings of the guide slots, and adjustment handles 1133 are located at the free ends of the adjustment bolts. The width of the guide slots can be adjusted by loosening or tightening the adjustment nuts, thereby adjusting the friction between the guide slot walls and the surfaces of the adjustment guide posts 1131, thereby securing and releasing the adjustment sliders 1132. Both the transfer mechanism bracket 111 and the receiving mechanism bracket 211 are frame structures. The two adjustment guide posts 1131 of the first spacing adjustment mechanism 113 are located at the front and rear ends of the transfer mechanism bracket 111, along the width of the product. The two adjustment sliders 1132 in each pair of adjustment sliders 1132 are located at the front and rear ends of the corresponding conveyor mounting plate 1121. The front and rear ends of the conveyor mounting plate 1121 are slidably mounted on the two adjustment guide posts 1131 via the two adjustment sliders 1132. When the width between the two first conveying rails 112 needs to be adjusted, loosen the adjusting bolt through the adjusting 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 through the adjusting 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 movement of the second conveyor rail 212. 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 mounted on the corresponding conveyor mounting plate 1121 of the second conveyor rail 212. The ends of the conveyor mounting plate 1121 of the second conveyor rail 212 are slidably mounted on the adjustment guide posts 1131 of the second spacing adjustment mechanism 213 via the linear bearings 2153. The adjustment sliders 1132 of the second spacing adjustment mechanism 213 are mounted on the ends of the two opening mechanism mounting plates 2151. The opening mechanism mounting plates 2151 are slidably mounted on the outer sides of the corresponding conveyor mounting plates 1121 via the adjustment sliders 1132. The opening drive cylinder 2152 is disposed between the corresponding opening mechanism mounting plate 2151 and the conveyor mounting plate 1121. During use, with the piston of the open driving cylinder 2152 extended, the second spacing adjustment mechanism 213 is adjusted so that the spacing between the two second conveying tracks 212 matches 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, making it easier for the tray grabbing mechanism 214 to place the grabbed tray on the empty tray stacking platform 220.

[0035] It is understood 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 gripping mechanism 214 includes a tray suction cup and a suction cup lifting drive mechanism 2144. The tray suction cup is provided with multiple 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 provided on the receiving mechanism bracket 211 along the width of the tray. The suction cup bracket 2141 is provided with an elongated hole. The suction cup mounting plate 2142 is mounted on the suction cup bracket 2141 by bolts passing through the elongated hole, so that the spacing and number of the suction cup mounting plates 2142 can be adjusted. The suction nozzle 2143 is detachably mounted on the lower surface of the suction cup mounting plate 2142 by magnetic attraction, so that the position of the suction nozzle 2143 can be adjusted to accommodate different sizes of trays. 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 sidewalls 222. The two sidewalls 222 are vertically mounted on the stacking platform support 221, which is connected to the stacking lifting mechanism 240. A support plate 2221 is provided at the bottom of the sidewalls 222 for supporting the tray stack. The sidewalls 222 support the edge of the bottom tray through the support plate 2221, thus supporting the tray stack. At the same time, the vertical sidewalls 222 block the sides of the tray stack to prevent it from tipping over.

[0037] Reference Figure 6 In this embodiment, the stacking platform support 221 is provided with a stacking platform lifting drive mechanism 223. The stacking platform lifting drive mechanism 223 is used to drive the sidewalls 222 to move upward and downward within a certain range, so that the sidewalls 222 extend into the empty tray receiving mechanism 210 to receive the trays and place the stacked trays on the AGV docking mechanism 300. The stacking platform support 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 perpendicularly arranged at both ends of the horizontal plate 2211, forming a U-shaped frame with the horizontal plate 2211 to facilitate the placement of the stacked trays on the AGV docking mechanism 300. Adjustment slots 22111 are provided at both ends of the horizontal plate 2211. The side plates 2212 slide within the adjustment slots 22111 to adjust the spacing between the sidewalls 222 to accommodate different tray lengths. A scale 22212 is provided above the slide 22111, and a step is provided to facilitate the adjustment of the spacing between the ribs 222 on both sides. Two ribs 222 are provided on each side plate 2212, and the ribs 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 rib 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 rib 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 ribs 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 should preferably be photoelectric sensors, and the blocking mechanism 114 should preferably be 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 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 conveyor mechanism 320. The docking conveyor mechanism 320 is disposed within the docking channel 310. The entrance of the docking channel 310 is disposed 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 conveyor mechanism 320 transports the tray stack on the empty tray receiving mechanism 200 through the docking channel 310 and delivers it to the AGV robot's carrying platform. It is understood that the docking conveyor mechanism 320 can utilize a roller belt or a conveyor belt. In this embodiment, the docking conveyor mechanism 320 utilizes a conveyor belt. Guide baffles 321 are disposed on both sides of the docking conveyor mechanism 320. The guide baffles 321 are disposed along the transport direction of the docking conveyor mechanism 320 to prevent the tray stack from tipping over and collapsing during movement.

[0040] In the automatic material receiving machine of an 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 moved to the conveying mechanism with fewer products in the next production line under the drive of the product lifting mechanism 120 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. 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 conveyor mechanism 320. The docking conveyor mechanism 320 transports the tray stack to the AGV robot, thereby improving the return efficiency of the trays.
