DETAILED DESCRIPTION

[0095] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0096] Please refer to Figures 1-4 The present application provides the following technical solutions:

[0097] A strip-shaped bagged product processing line comprises a tray 100 as a product carrier, the tray 100 is overall rectangular, and a plurality of slots for placing products are arranged on the tray 100. One end of the slot is an open end as a port for the products to enter, and the other end is a closed end.

[0098] This processing line includes a loading unit and an unloading unit. The loading unit, as the inlet section of the processing line, loads products into pallets 100. The unloading unit, as the outlet section of the processing line, unloads products from pallets 100 and discharges them in groups. An intermediate unit 6 is provided between the loading and unloading units. Unit 6 includes a first intermediate line 61 and a second intermediate line 62. The first intermediate line 61 transports pallets 100 containing products from the loading unit to the unloading unit, and a sterilization chamber 63 is provided on the first intermediate line 61. The second intermediate line 62 transports unloaded pallets 100 from the unloading unit back to the loading unit. Figure 1 As shown, the first intermediate line 61 and the second intermediate line 62 form a "D" shape.

[0099] Both the loading and unloading units include a chain conveyor mechanism 1, a loading and unloading mechanism 2, a pallet supply mechanism 3, a pallet conveying mechanism 4, and a pallet arrangement mechanism 5. In addition to the above mechanisms, the unloading unit also includes a grouping mechanism 7.

[0100] The layout structure of the loading unit is as follows:

[0101] The chain conveyor mechanism 1 serves as the product inlet of the palletizing unit, and its chain is equipped with several conveyor frames 131. The conveyor frames 131 are used to carry the products. The chain conveyor mechanism 1 transports the products to the loading and unloading mechanism 2, and the pallet supply mechanism 3 transports empty pallets 100 to the pallet conveying mechanism 4. The loading and unloading mechanism 2 pushes the products from the chain conveyor mechanism 1 into the pallets 100 on the pallet conveying mechanism 4. Then, the pallet conveying mechanism 4 pushes the pallets to the pallet arranging mechanism 5 for arrangement.

[0102] A tray-loading robot 64 is provided near the intermediate unit 6 in the tray-loading unit. The tray-loading robot 64 can pick up the tray 100 with products from the tray arrangement mechanism 5 and place it on the first intermediate line 61. It can also pick up the empty tray 100 on the second intermediate line 62 and place it on the tray supply mechanism 3 in the tray-loading unit.

[0103] The layout of the unloading unit is as follows:

[0104] The pallet supply mechanism 3 serves as the entry point for the entire unloading unit, and is located on one side of the exit end of the first intermediate line 61. Corresponding to the output end of the pallet supply mechanism 3 are a pallet conveying mechanism 4 and a loading / unloading mechanism 2. The pallet supply mechanism 3 transports pallets 100 containing products to the pallet conveying mechanism 4, where the loading / unloading mechanism 2 unloads the products and pushes them onto the corresponding chain conveyor mechanism 1. The pallet conveying mechanism 4 then pushes the empty pallets 100 to the pallet arranging mechanism 5, completing the unloading operation. The chain conveyor mechanism 1 then transports the products to the grouping mechanism 7, where they are grouped and output. It should be noted that the operation process of the loading / unloading mechanism 2 is reversed in the loading and unloading units.

[0105] The tray unloading robot 65 is arranged at one end of the intermediate unit 6 close to the tray unloading unit, and can grasp the tray 100 on the first intermediate line 61 to the tray feeding mechanism 3 of the tray unloading unit, and can grasp the empty tray on the tray feeding mechanism 5 of the tray unloading unit to the second intermediate line 62.

[0106] Through the structure of the scheme, the pipeline type small bagged product disinfection operation can be realized, and the processing line is a circulating line, the tray 100 on the processing line is in a circulating use state in the whole processing process, the whole processing line adopts an unattended operation mode, there is no manual operation link, and the working efficiency is very high.

[0107] On the basis of the above-mentioned embodiment, referring to Figures 2-4 , the tray 100 specifically comprises a tray base plate 101 in the shape of a rectangular plate body, the length direction of the tray base plate 101 is the longitudinal direction, the width direction is the transverse direction, and one side of the tray base plate 101 in the transverse direction is the feeding side of the tray 100; an upper groove is formed on the upper side of the plate body of the tray base plate 101, one side of the upper groove facing the feeding side is an open port, and the other side is a closed end. A plurality of tray partitions 102 are arranged in the upper groove, the tray partitions 102 are arranged in a straight line array, the distribution direction of the tray partitions 102 is the longitudinal direction of the tray base plate 101, and one end of the tray partition 102 extends to the edge of the feeding side of the upper groove.

[0108] The tray is used for placing a flexible long bag product, the product itself can be liquid or powder, etc., by placing the product on the tray, the product can be uniformly treated in the subsequent production link, such as product disinfection. Because the flexible bag product itself has a certain instability in shape and is difficult to clamp, the product can be effectively stored and placed by the tray, so that the product can be treated in the production link of the assembly line.

[0109] Referring to Figure 3 , a lower groove is formed on the lower side of the tray base plate 101, the lower groove is upwardly recessed, and the lower groove is arranged opposite to the upper groove, a plurality of reinforcing plates in the longitudinal and transverse directions are arranged in the lower groove. A plurality of air holes are formed on the plate body of the tray base plate 101, and the air holes are arranged in a rectangular array.

[0110] Because the trays are placed and stacked in large quantities in the production line type processing process, in order to reduce the self weight of the tray as much as possible, the lower groove is arranged as a weight reduction structure. In addition, through the lower groove structure, the thickness of the tray base plate 100 is reduced, and the peripheral wall of the lower groove is in the shape of a complete ring, which is different from the upper groove. When the product is disinfected by using ozone or steam gas, the tray base plate 101 with smaller thickness is more conducive to the passage of the gas, and the ring-shaped groove structure can more easily converge the disinfection gas.

[0111] Referring to Figure 4 A tray end plate 103 is arranged on each of the upper sides of the longitudinal ends of the tray substrate 101, and the two tray end plates 103 extend to the longitudinal outer sides of the tray substrate 101. An arc-shaped notch is formed in the outer edge portion of the tray end plate 103. A tray gasket 105 is arranged on the tray end plate 103, the tray gasket 105 is made of rubber material, and a plurality of convex points are arranged on the upper surface of the tray gasket 105.

[0112] A tray positioning assembly 104 is arranged on each of the longitudinal ends of the tray substrate 101, and the tray positioning assembly 104 is used for positioning when the tray is vertically stacked and placed. The tray positioning assembly 104 includes a tray positioning column and a tray positioning hole. The tray positioning column is arranged on the upper side of the tray substrate 101, and the tray positioning hole is arranged on the lower side of the tray substrate 101 and coaxial with the tray positioning column. The tray positioning column can be inserted into the tray positioning hole.

[0113] The tray end plate 103 serves as an upper end limiting plate for the sliding of the tray during the pipeline operation, and forms a stepped structure together with the longitudinal ends of the tray substrate 101. On the other hand, the notches on the two sides of the tray end plate 103 can be used as the force points of the mechanical arm grabbing tool. The function of the tray positioning assembly 104 is to fix the position when the tray 100 is stacked and placed.

[0114] On the basis of the above-mentioned embodiments, referring to Figures 5-9 The chain conveying mechanism 1 includes an elongated conveying frame 11, which is a support structure of the chain conveying mechanism, and the length direction of the conveying frame 1 is the conveying direction thereof. A conveying chain 12 is arranged in the conveying frame 11, and the conveying chain 12 is a combination of a chain wheel and a chain. The chain 121 in the conveying chain 12 is arranged in a ring shape in the conveying frame 11. A conveying frame group 13 is arranged on the conveying chain 12, and the conveying frame group 13 includes a plurality of conveying frames 131, one of which is fixedly arranged on each section of the chain 121.

[0115] Each conveying frame 131 comprises a frame connecting portion 1311 which is a rectangular block, and the conveying frame 131 is fixedly connected with the conveying chain 12 through the frame connecting portion 1311. A plurality of frame partitions 1312 are arranged in parallel on the frame connecting portion 1311, and the frame partitions 1312 form placing slots therebetween. The placing slots are used for placing the long strip bagged products to be loaded. The height of the frame partitions 1312 is lower than the products thereon, for example, the bagged oral liquid products conveyed by the mechanism of the present scheme, when the products are placed in the placing slots, the length direction of the products is parallel to the length direction of the placing slots, the products are in a horizontal state, and the upper portions of the products are exposed on the upper side of the conveying frame 131. With the rotation of the chain 121 of the conveying chain 12, the conveying frame 131 and the products thereon are conveyed to the discharging position together, and by means of the push plate structure in the loading and unloading mechanism 2, the products are pushed out of the conveying mechanism by being pushed through above the conveying frame 131 and by pushing the exposed portion of the products on the conveying frame 131. As shown in Figure 6 , the conveying frame 131 has a rectangular structure, the length direction of the conveying frame 131 is perpendicular to the length direction of the conveying chain 121, and the discharging direction of the conveying mechanism is parallel to the length direction of the conveying frame 131.

[0116] Referring to Figure 6 , the conveying frame 131 of the present scheme adopts two different structural forms, both of which are the combination of the frame connecting portion 1311 and the frame partitions 1312, and the distribution structures of the frame partitions 1312 are different. One of them is a four-plate structure in which four frame partitions 1312 are arranged on the frame connecting portion 1311, and the other is a three-plate structure in which three frame partitions 1312 are arranged. One of the frame partitions 1312 of the four-plate structure is arranged on the edge portion of the frame connecting portion 1311, and the other three are arranged in sequence, and there is space left on the other edge portion of the frame connecting portion 1311. The conveying frame 131 of the three-plate structure is a group with the conveying frame 131 of the four-plate structure, and this group is provided with seven placing positions for placing products. The frame partitions 1312 of the three-plate structure leave a spacing on both sides of the frame connecting portion 1311, one of the spacings is equivalent to a complete placing slot, and the other spacing is combined with the adjacent four-plate structure conveying frame 131 to form a placing slot.

[0117] This structural form of the present scheme considers the optimal utilization rate of the product placing space. Under this structure, when the chain 121 rotates to the end portion, the position of the conveying frame 131 on the chain 121 rotates from the upper side to the lower side, and the conveying frame 131 of the present scheme is more likely to make the products thereon fall off.

[0118] The conveyor frame 11 includes a rectangular conveyor belt compartment 111, which is hollow inside and open at the top. A conveyor chain 12 is disposed in the upper region of the conveyor belt compartment 111. A conveyor support 112 is provided below the conveyor belt compartment 111 to support it. The conveyor support 112 includes several support rods, such as... Figure 5 As shown, the lower part of the conveyor support 112 is equipped with rollers and height-adjustable support blocks.

The discharging and tray loading of the products on the chain transmission mechanism 1 are realized by means of the poking mechanism 22. The working directions of the loading and unloading mechanism 2 in the tray loading unit and the tray unloading unit are opposite.

[0130] On the basis of the above-mentioned embodiments, the loading and unloading rack 21 includes a loading and unloading base 214 and a loading and unloading cover 215.

In addition, warning lights can be arranged on the loading and unloading cover 215, corresponding sensing equipment is installed according to actual needs, and the working state of the equipment is warned in combination with the warning lights.

[0131] On the basis of the above-mentioned embodiments, referring to Figures 12-14 The unloading and loading poking mechanism 22 comprises an unloading and loading guide frame 221 fixedly arranged on the upper side of the unloading and loading base 214, and a plurality of parallel guide grooves are formed in the unloading and loading guide frame 221, the width of the guide grooves corresponds to the product to be unloaded and loaded, and the length direction of the guide grooves is parallel to the discharging direction of the first material port 212. An unloading and loading poking assembly is arranged corresponding to the unloading and loading guide frame 221, and the unloading and loading poking assembly can poke the product at the product channel to the first material port 212, and when the unloading and loading poking assembly pokes the product, the product moves in the guide groove of the unloading and loading guide frame 221.

[0132] The unloading and loading poking assembly specifically comprises an unloading and loading poking frame 222 and a plurality of unloading and loading poking plates 223, wherein the unloading and loading poking frame 222 is arranged above the unloading and loading guide frame 221; the unloading and loading poking plates 223 are arranged in a distributed manner on the unloading and loading poking frame 222, and the length direction of the unloading and loading poking plates 223 is perpendicular to the discharging direction of the first material port 212; and the distribution direction of the unloading and loading poking plates 223 on the unloading and loading poking frame 222 is parallel to the discharging direction of the first material port 212.

[0133] The unloading and loading poking frame 222 and the unloading and loading poking plate 223 are combined to realize the pushing of the product. For the realization of this function, various structures can be adopted, as long as the product at the product channel position can be poked as a whole into the unloading and loading guide frame 221, and then pushed for a distance into the subsequent tray 100.

[0134] On the basis of the above-mentioned embodiments, the unloading and loading poking frame 222 is slidably connected with the unloading and loading base 214, and the sliding direction is the discharging direction of the first material port 212; the unloading and loading poking frame 222 is powered to slide by the poking frame driving mechanism 224, and the poking frame driving mechanism 224 is arranged on the unloading and loading base 214.

[0135] The unloading and loading poking frame 222 comprises an upper frame and a lower frame, wherein the upper frame is arranged above the unloading and loading guide frame 221, and the unloading and loading poking plates 223 are connected with the upper frame; the lower frame is fixedly connected with both ends of the upper frame, and the lower frame is located below the unloading and loading guide frame 221; and the poking frame driving mechanism 224 is connected with the lower frame.

[0136] As shown in Figure 14 The poking frame driving mechanism 224 comprises a poking frame sliding rail 2241 and a poking frame lead screw 2242. The poking frame sliding rail 2241 is fixedly arranged on the unloading and loading base 214, and the lower frame is slidably connected with the poking frame sliding rail 2241. The poking frame lead screw 2242 is rotatably arranged on the unloading and loading base 214 and is threadedly connected with the lower frame, and the poking frame lead screw 2242 is connected with the motor arranged in the unloading and loading base 214 through a belt wheel combination.

[0137] The present scheme considers the problem of the upper frame setting the loading and unloading stirring plate 223, the upper frame itself will vibrate when stirring, resulting in reduced stability. The sliding connection position and power position of the loading and unloading stirring frame 222 are set on the lower frame, and the stable lower structure support force is provided by the combination of the slide rail and the screw rod, so that the upper frame can obtain stable support force from the lower frame. With the action of the stirring frame driving mechanism 224, the loading and unloading stirring frame 222 is reciprocated by the reciprocating movement of the stirring frame screw rod 2242, and a batch of products, that is, long bagged products, can be pushed out each time the loading and unloading stirring frame 222 moves horizontally towards the first material port 212.

[0138] On the basis of the above-mentioned embodiment, the loading and unloading stirring plate 223 is rotationally connected with the upper frame, the rotation axis direction is parallel to the length direction of the loading and unloading stirring plate 223, and four loading and unloading stirring plates 223 are arranged in total. The loading and unloading stirring plate 223 closest to the product channel extends above the product channel, and the other end of the loading and unloading stirring plate 223 extends above the tray conveying mechanism 4. The products in the product channel position are stirred to the loading and unloading guide frame 221 by the loading and unloading stirring plate 223 at this position. The loading and unloading stirring plate 223 is driven by the stirring plate driving mechanism 225. The stirring plate driving mechanism 225 is linked with the rotation axis of the loading and unloading stirring plate 223, and drives the loading and unloading stirring plate 223 to reciprocate about its own rotation axis.

[0139] Through the swinging of the loading and unloading stirring plate 223 and the horizontal movement of the aforementioned loading and unloading stirring frame 222, the two actions are combined to realize continuous loading and unloading. The following is an explanation of the action flow of the device:

[0140] The swinging of the loading and unloading stirring plate 223 towards the first material port 212 is action A; the swinging of the loading and unloading stirring plate 223 towards the product channel for resetting is action B; the horizontal movement of the loading and unloading stirring frame 222 towards the first material port 212 is action C; and the horizontal movement of the loading and unloading stirring frame 222 towards the product channel for resetting is action D. The initial state is that the loading and unloading stirring plate 223 is twisted and raised towards the product channel direction, and the loading and unloading stirring plate 223 leaves a gap with the upper end surface of the loading and unloading guide frame 221, and at this time the loading and unloading stirring frame 222 is close to the product channel. The action sequence of the stirring mechanism 22 is:

[0141] 1. The loading and unloading stirring plate 223 performs action A to stir the products on the product channel to the loading and unloading guide frame 221, and the lower end of the plate body of the loading and unloading stirring plate 223 is attached to one end of the products, that is, the end close to the product channel.

[0142] 2. The loading and unloading stirring frame 222 performs action C, the loading and unloading stirring plate 223 keeps the posture unchanged, and the loading and unloading stirring frame 222 moves horizontally to drive the loading and unloading stirring plate 223 to push the products on the loading and unloading guide frame 221 by a distance.

[0143] 3, the loading and unloading of the dial 223 to perform action B, loading and unloading of the dial 223 to lift the reset.

[0144] 4, the loading and unloading of the dial 222 to perform action D, loading and unloading of the dial 222 to move the reset.

[0145] Repeat the process, you can push the next batch of products.

[0146] On the basis of the above embodiments, see Figure 14 and Figure 15 , the loading and unloading of the dial 222 is provided with four dial 223, through the cooperation of four dial 223, the products are pushed in several times of horizontal displacement through the rack body of the loading and unloading guide frame 221, and are sent into the corresponding tray. Dial drive mechanism 225 includes dial drive 2251, dial drive 2251 can be selected by cylinder, one end of dial drive 2251 is rotatably connected with the loading and unloading dial 222; the other end is rotatably connected with the dial connecting piece 2252, and the dial connecting piece 2252 is fixedly connected with the rotating shaft of the loading and unloading dial 223. The dial connecting piece 2252 can be selected by block structure.

[0147] Considering the linkage of four loading and unloading dial 223, the rod structure of dial linkage 2253 is provided, the dial linkage 2253 is selected by telescopic rod structure, the inner rod and the outer rod are threadedly connected, and the both ends of the rod body are connected with the rotating shafts of the adjacent two loading and unloading dial 223 through a dial connecting piece 2252 respectively. As shown in Figure 13 and Figure 15 As shown in the drawings, two dial drive 2251 are arranged on one side of the loading and unloading dial 222, and two groups of dial linkage 2253 and dial connecting piece 2252 are arranged on the other side, so as to realize the linkage of four loading and unloading dial 223.

[0148] The application mode of the loading and unloading mechanism 2 in the tray loading unit and the tray unloading unit is different, and the difference mainly lies in that the pushing direction is opposite due to the swing direction of the loading and unloading dial 223 and the movement direction of the loading and unloading dial 222. The overall working principle is the same, and adaptive adjustment can be made to the driving mechanism.

[0149] On the basis of the above embodiments, see Figures 16-21, the tray supply mechanism 3 comprises a tray rack 31 of a rectangular frame structure, and the tray rack 31 is provided with a tray slide 311 corresponding to a tray, and the tray can slide on the tray rack 31 through the tray slide 311; one end of the tray 311 extends to the feeding side of the tray rack 31, and the other end extends to the discharging side of the tray rack 31. The first supply mechanism 32 and the second supply mechanism 33 are respectively arranged on the tray rack 31, and the supply paths of the two are straight paths. The first supply mechanism 32 takes the feeding side of the tray rack 31 as the starting point, and can supply the tray to the middle position of the tray rack 31; the second supply mechanism 33 takes the discharging side of the tray rack 31 as the end point, and the supply starting point is close to the starting point of the first supply mechanism 32.

[0150] The scheme combines two supply mechanisms to form the overall supply path of the tray rack 31, and the combination of the two supply mechanisms can reduce the manufacturing cost of a single supply structure due to the excessively long path length, and can also reduce the maintenance difficulty of the equipment in use and reduce the maintenance cost.

[0151] On the basis of the above-mentioned embodiment, referring to Figure 16 and Figure 17 , the first supply mechanism 32 comprises a first supply push rack 321 and a first supply driving mechanism 322. The rack body of the first supply push rack 321 can be moved to the lower side of the tray, the first supply push rack 321 comprises a first rack plate, which is a "Y" shaped plate body, a plurality of mounting holes are formed in the plate body, the rack plate is connected with the first supply driving mechanism 322, and the two branch ends of the rack plate on the same side are respectively provided with push blocks. The push blocks are arranged at positions of the first rack plate facing the feeding side of the tray rack 31, and when the first supply push rack 321 moves, the push blocks abut against the edge positions of the trays close to them. The first supply driving mechanism 322 selects a rodless cylinder to drive the first supply push rack 321 to translate towards the middle area of the tray rack 311.

[0152] On the basis of the above-mentioned embodiment, referring to Figures 18-20 , the second supply mechanism 33 comprises a second supply push rack 331 and a second supply driving mechanism 332. The upper part of the rack body of the second supply push rack 331 can extend to the side position of the tray facing the feeding side of the tray rack 31; the second supply driving mechanism 332 is linked with the second supply push rack 331, and can drive the second supply push rack 331 to translate towards the discharging side of the tray rack 311.

[0153] The second supply pusher 331 consists of a second frame plate 3311, a second upright 3312, and a second push rod 3313. The second frame plate 3311 is an isosceles trapezoidal plate, and its plate body is linked with the second supply drive mechanism 332. Two second uprights 3312 are symmetrically arranged on both sides of the long side of the second frame plate 3311, and the second uprights 3312 extend upward. A second push rod 3313 is rotatably mounted on the upper end of each second upright 3312, and the rod body of the second push rod 3313 is rotatably connected to the upper part of the second upright 3312; in its natural state, the second push rod 3313 remains in an inclined state, with its end facing the feed side of the pallet frame 31 in a low horizontal position, that is... Figure 18 , Figure 19 and Figure 20 In the state shown, the lower edge of the second push rod 3313 is in contact with the upper structure of the second upright 3312. When the second supply pusher 331 moves toward the discharge side, the second push rod 3313 will not rotate further due to the limitation of the second upright 3312, so the pallet can be moved. When the first supply pusher 321 pushes the pallet to the position of the second supply pusher 331, the pallet first pushes the second push rod 3313, causing it to rotate. As the second push rod 3313 is pushed to a near-horizontal state, the pallet can continue to move forward past the upper side of the second push rod 3313. After the pallet leaves the position of the second push rod 3313, the second push rod 3313 returns to its tilted state under the action of its own weight.

[0154] Unlike the first supply drive mechanism 322, the second supply drive mechanism 332 uses a lead screw structure as its drive structure, including a second drive seat 3321 fixedly installed inside the pallet frame 31. The second drive seat 3321 is located below the first supply mechanism 32 and has a long track structure, such as... Figure 21 As shown, the second drive seat 3321 has a hollow interior, within which a second lead screw is rotatably connected. A second motor 3322 is fixedly connected to one end of the second drive seat 3321, with its motor shaft linked to the second lead screw. A second sliding seat 3323 is also slidably connected within the cavity. Both sides of the second drive seat 3321 extend outside the cavity, with the lower part of the second sliding seat 3323 located inside the second drive seat 3321 and threadedly connected to the second lead screw. The upper part is fixedly connected to the second support plate 3311 in the second supply pusher 331. Because the second supply pusher 331 needs to ensure docking with the pallet conveying mechanism 4, a lead screw-driven structure is adopted. Compared to cylinder-driven actions, the lead screw structure offers more precise position adjustment and is easier to debug.

[0155] On the basis of the above-mentioned embodiments, the displacement of the second feeding mechanism 332 is controlled. The present embodiment provides a design of the control mechanism, and the second feeding driving mechanism 332 further comprises a second sensor group 3324, which comprises a plurality of second sensors arranged outside the second driving seat 3321, and the second sensors are photoelectric sensors. The second triggering piece is fixedly connected with the second sliding seat 3323, and the second triggering piece is a bent plate structure. When the second sliding seat 3323 moves to the position of the second sensor, the second triggering piece triggers the second sensor to make an electrical signal feedback.

[0156] On the basis of the above-mentioned embodiments, the lower part of the tray rack 31 is provided with a roller set and a cushion block set; the cushion block is a bolt structure with adjustable height. The roller set and the cushion block set are combined to facilitate the turnover of the mechanism and the positioning in use. The tray rack 31 further comprises a tray guide plate 312 arranged on the upper side of the tray slide 311, and the end of the tray guide plate 312 towards the feeding side of the tray rack 31 is a trumpet structure. The position of the tray is adjusted by the tray guide plates 312 on both sides to facilitate cooperation with the tray conveying mechanism 4. The tray guide plate 312 is fixedly connected with the outer side wall of the tray rack 31 through a tray guide mounting piece 313, and the upper part of the tray guide mounting piece 313 is provided with a plug rod towards the middle part of the tray rack 31, and the tray guide plate 312 is inserted with the plug rod of the tray guide mounting piece 313. As shown in Figure 19 , the plug rod is transversely arranged, and a locking rod is threadedly connected with the upper side of the plug rod to fix the plug rod. The tray guide plate 312 is provided with a sliding groove corresponding to the plug rod to facilitate the position adjustment of the tray guide plate 312.

[0157] On the basis of the above-mentioned embodiments, referring to Figures 22-25 , the tray conveying mechanism 4 comprises a conveying rack 41 which is the main support structure of the conveying mechanism, and a conveying tray rack 42 is arranged on the conveying rack 41, which is used to carry the tray 100 to be conveyed. The conveying rack 41 is further provided with a first conveying mechanism 43 and a second conveying mechanism 44. The first conveying mechanism 43 is connected with the conveying tray rack 42 and can drive the conveying tray rack 42 to translate in the first direction; the second conveying mechanism 44 is arranged on the moving path of the conveying tray rack 42 and can drive the conveying tray rack 42 to translate in the second direction, and the second direction intersects with the extension line of the first direction moving path. The present embodiment is used to change the transmission path of the tray 100, and serves as the node of the tray conveying route change at the connection position of the loading and unloading mechanism 2 and the tray arrangement mechanism 5.

[0158] On the basis of the above-mentioned embodiments, the conveying frame 41 comprises a rectangular long shell-shaped conveying shell 411, and main structural components of the first conveying mechanism 43 are arranged inside the conveying shell 411; a conveying support frame 412 is arranged below the conveying shell 411, and the conveying support frame 412 can be reformed according to actual needs, as long as it can stably support the conveying shell 411. As shown in Figure 22 The lower end of the conveying support frame 412 of the present scheme is provided with a roller set and a support block set, the support block set is selected to have a block body with a screw structure, and the height position of the support block is adjusted by rotating the support block with the aid of the screw.

[0159] On the basis of the above-mentioned embodiments, the conveying tray frame 42 comprises a conveying frame body 421 and a conveying frame positioning member 422. The length direction of the conveying frame body 421 is parallel to the movement direction of the first conveying mechanism, and the conveying frame body 421 can be linked with the first conveying mechanism 43. The conveying frame body 421 comprises a bottom plate and side plates located at both ends of the length direction of the bottom plate, and the conveying frame positioning member 422 is arranged at the upper end of each side plate, and the conveying frame positioning member 422 and the upper end of the side plate form a stepped structure. The conveying frame positioning member 422 is symmetrically arranged at the upper part of the conveying frame body 421, and the spacing between the two conveying frame positioning members 422 corresponds to the length direction of the tray. The end of the two conveying frame positioning members 422 facing the second conveying mechanism 44 forms a horn structure. The conveying frame body 421 is used as the main bearing structure of the tray during conveying. The conveying frame positioning member 422 is used as a guide and adjustment structure, so that the tray is clamped between the two conveying frame positioning members 422 when it is located on the conveying frame body 421. Thus, it is ensured that the tray will not be separated when the first conveying mechanism 43 drives the whole conveying tray frame 42 to move. The present application is not limited to the specific structure of the conveying frame positioning member 422, and any structure that can achieve the above-mentioned functions can be used. Figure 22 As shown in the accompanying drawings, the conveying tray frame 42 is located at the conveying position of the first conveying mechanism 43 corresponding to the second conveying mechanism 44. The conveying tray frame 42 is located at the conveying position of the first conveying mechanism 43 corresponding to the second conveying mechanism 44. Figure 22 The right end of the conveying frame 41 in Figure 22 is the entrance position of the tray into the mechanism, and the conveying tray frame 42 waits for the tray to be placed in it at this position. How to place the tray on the conveying tray frame 42 is not the key point of the present scheme, and various structural forms can be used to achieve it, such as using an external pushing structure to push the tray onto the conveying tray frame 2, or using a robot to grasp and place the tray.

[0160] Based on the above implementation scheme, the first conveying mechanism 43 includes a first transmission assembly 431 and a first guide assembly 432. The first transmission assembly 431 is disposed inside the conveyor housing 411 and is a conveyor belt structure, including a driving pulley, a driven pulley, and a conveyor belt sleeved on both. A block structure with a connecting hole is fixedly disposed on the conveyor belt as a connecting block, which also serves as the moving end of the first transmission assembly 431. This moving end is fixedly connected to the conveyor pallet frame 42. The first guide assembly 432 includes two guide rods, which are disposed on both sides of the belt of the first transmission assembly 431.

[0161] Corresponding to the first conveying mechanism 43, such as Figure 25 As shown, the conveyor pallet frame 42 includes a conveyor connecting seat 423, which is located at the lower part of the conveyor frame body 421 of the conveyor pallet frame 42. In this design, two conveyor connecting seats 423 are provided. One conveyor connecting seat 423 is fixedly connected to the moving end of the first transmission assembly 431 in the middle, and slidably connected to two guide rods on both sides. The other conveyor connecting seat 423 is slidably connected to guide rods on both sides.

[0162] This structure enables the first conveying mechanism 43 to drive the conveying pallet frame 42. The first conveying mechanism 43 drives the conveying pallet frame 42 to reciprocate, transferring the position of one pallet 100 each time.

[0163] Based on the above implementation scheme, the second conveying mechanism 44 includes a second transmission assembly 441 and a second pusher 442. The second transmission assembly 441 is disposed on the belt side of the first transmission assembly 431, and is a cylinder assembly, with the movement direction of the movable end of the cylinder perpendicular to the movement direction of the first transmission assembly 431. The second pusher 442 is fixedly connected to the movable end of the second transmission assembly 441 and can push the pallet on the conveying pallet frame 42. Figure 23 As shown, the lower part of the second pusher 442 is fixedly connected to the moving end of the second transmission assembly 441, and the upper part is provided with a long strip-shaped horizontal plate. The length direction of the horizontal plate is parallel to the length direction of the conveying pallet frame 42, and a pad is provided on the side of the horizontal plate facing the conveying pallet frame 42.

[0164] When the pallet frame 42 moves to the position of the second conveying mechanism 44 under the drive of the first conveying mechanism 43, the cylinder in the second transmission assembly 441 pushes the second pusher 442 to move, pushing the pallet to the second direction. The activation time of the second conveying mechanism 44 can be achieved using existing technology, such as setting up a photoelectric sensor, proximity sensor, contact switch, or other structure that can provide position feedback for the pallet frame 42, which serves as the activation signal for the second transmission assembly 441.

[0165] On the basis of the above-mentioned embodiments, the conveying tray frame 42 can be further divided into an upper frame and a lower frame structure, the lower frame is connected with the first conveying mechanism 43 and can move horizontally, the upper frame is rotationally connected with the lower frame, and a servo motor is arranged at the rotation position of the two frames as a driving power source for rotation. In this structure, the second conveying mechanism 44 can be arranged at more angles in combination with the first conveying mechanism 43, instead of the straight conveying in the above-mentioned embodiments. Only the first conveying mechanism 43 needs to convey the conveying tray frame 42 to the position of the second conveying mechanism 44, and then the upper frame of the second tray frame 42 is correspondingly rotated to match the angle of the second conveying mechanism 44.

[0166] On the basis of the above-mentioned embodiments, referring to Figure 26 , the tray arrangement mechanism 5 comprises an arrangement support 51 of a rectangular frame type support structure, an arrangement slide 52 is arranged at the upper end of the arrangement support 51, the arrangement slide 52 is horizontally arranged, one end thereof is an open end as an entering end of the tray 100, and the internal spacing of the arrangement slide 52 corresponds to the longitudinal length of the tray 100. The arrangement slide 52 comprises two symmetrically arranged slide rails, and the longitudinal section of the slide rail is in the shape of “L”.

[0167] In combination with the transfer equipment corresponding to the tray 100, such as a horizontal pushing equipment corresponding to the tray 100, a plurality of trays 100 can be placed side by side on the arrangement frame to ensure that they are placed in order to form a tray group, thereby facilitating subsequent transfer and production and processing.

[0168] A buffer 53 is arranged at the other end of the arrangement slide 52 away from the entering end, the buffer 53 is a spring rod, and the arrangement of the buffer 53 can avoid damage to the tray when the tray is pushed and reduce the impact on the arrangement frame. Opposite to the buffer 53, a reverse sending prevention assembly 54, also called a check assembly, is arranged at the entering end of the arrangement slide 52, which can avoid the possibility that the tray 100 slides out of the entering end due to improper horizontal angle adjustment of the arrangement frame.

[0169] On the basis of the above-mentioned embodiments, referring to Figure 27 and Figure 28 ​The grouping mechanism 7 comprises a grouping rack 71, and a grouping inlet 711 and a grouping outlet 712 are arranged on the grouping rack 71. The grouping inlet 711 is arranged corresponding to the chain conveying mechanism 1 and can be connected to the chain conveying mechanism 1; the grouping outlet 712 is arranged corresponding to external equipment and receives the grouped product groups. A grouping discharge outlet 713 is further arranged on the grouping rack 71, and the grouping discharge outlet 713 is used for discharging the products that do not normally enter the grouping outlet 712. The grouping inlet 711 and the grouping discharge outlet 713 are arranged in the same straight line direction, forming a product channel for the products to enter and discharge, and the grouping outlet 712 is arranged on one side of the product channel, and the discharge direction of the grouping outlet 712 is perpendicular to the direction of the product channel. The grouping mechanism 72 is arranged inside the grouping rack 71, and the grouping mechanism 72 can push the products from the product channel to the grouping outlet 712.

[0170] The grouping mechanism 72 comprises a grouping guide rack 721 and a grouping material shifting assembly. The grouping guide rack 721 is fixedly arranged inside the grouping rack 71.

The number of the guide grooves decreases along the direction of the guide grooves. Figure 30 and Figure 31 As shown in FIGS. 1 and 2, the grouping guide rack 721 has 60 groove positions at the inlet end and 6 groove positions at the outlet end, so that the products are grouped into groups of ten. The grouping material shifting assembly is arranged corresponding to the grouping guide rack 721. The grouping material shifting assembly can shift the products in the product channel to the grouping outlet 712, and the products move in the guide grooves of the grouping guide rack 721 when the grouping material shifting assembly shifts the products. The grouping material shifting assembly can have a structure similar to the aforementioned tray shifting assembly.

[0171] When different grouping requirements need to be met, the corresponding grouping guide rack 721 can be manufactured and replaced.

[0172] On the basis of the above-mentioned embodiments, the grouping material shifting assembly comprises a grouping material shifting rack 722 and a grouping material shifting plate 723. The upper part of the grouping material shifting rack 723 is arranged above the grouping guide rack 721, and the grouping material shifting plate 723 is rotatably connected to the grouping material shifting rack 722. The lower part of the grouping material shifting rack 723 is arranged below the grouping guide rack 721, and the lower part of the grouping material shifting rack 723 is connected to the screw rod driving mechanism. The screw rod is rotatably connected to the grouping rack 71 and is threadedly connected to the lower part of the grouping guide rack 721. A motor is arranged to drive the screw rod to rotate in the forward and reverse directions. The screw rod is driven to reciprocate by the motor, so that the grouping material shifting rack 722 is driven to reciprocate horizontally. The grouping material shifting plate 723 is driven to swing in cooperation with the reciprocating movement of the grouping material shifting rack 722. The swinging movement of the grouping material shifting plate 723 can be achieved by means of a cylinder. Figure 29As shown, one end of the air cylinder is rotationally connected with the group pushing frame 722, the other end is rotationally connected with one end of a connecting block, and the other end of the connecting block is rotationally connected with the rotating shaft of the group pushing plate 723. When the air cylinder extends and retracts, the rotating shaft of the group pushing plate 723 rotates accordingly. One group pushing plate 723 on the group pushing frame 722 extends above the chain conveying mechanism 1, and through its swing, the product is pushed off the chain conveying mechanism 1, so that the product enters the group guide frame 721, and then through the translation of the group pushing frame 722, the product is moved a distance, so that the product moves along the guide groove of the group guide frame 721.

[0173] On the basis of the above-mentioned embodiments, referring to Figure 30 and Figure 31 , the group guide frame 721 includes an inlet guide part 7211, which is arranged near the product channel, and the number of guide grooves on the inlet guide part 7211 is equal to the total number of products discharged by the grouping mechanism 7 at one time. In this scheme, the number of guide grooves on the inlet guide part 7211 is 60. A plurality of intermediate guide parts 7212 are arranged opposite to the inlet guide part 7211, and the number of intermediate guide parts 7212 is adjusted according to the actual required conveying distance. In this scheme, two intermediate guide parts 7212 are arranged, and the number of guide grooves of the intermediate guide part 7212 is consistent with the number of guide grooves of the inlet guide part 7211. A first converging part 7213 is arranged opposite to the intermediate guide part 7212, the number of guide grooves at the inlet end of the first converging part 7213 is equal to the number of guide grooves of the intermediate guide part 7212, the number of guide grooves of the first converging part 7213 is reduced at the middle position and extends to the outlet end. The number of guide grooves at the outlet of the first converging part 7213 is reduced by half. A second converging part 7214 is arranged opposite to the first converging part 7213, and the number of guide grooves of the second converging part 7214 is equal to the number of groups of products discharged at one time. The guide groove at the outlet position of the first converging part 7213 corresponds to the inside of the guide groove of the second converging part 7214, which is no longer separated, and is a groove body. As shown in Figure 31 , the second converging part 7214 of this scheme is provided with six guide grooves.

[0174] According to the actual situation, if the number of guide grooves at the inlet guide part 7211 is larger, an intermediate structure similar to the first converging part 7213 can be additionally arranged between the first converging part 7213 and the second converging part 7214, so that the number of guide grooves is gradually reduced. This kind of decreasing transmission and convergence can make the product movement more orderly and less likely to be stuck in the guide groove.
