Description

Technical Field

[0001] The invention relates to an automatic sorting and separation device for long strip fish products, belonging to the technical field of fish product sorting. Background Art

[0002] At present, in the process of processing fish products, the sorting of products of different lengths is mainly done manually, which requires a lot of labor and the degree of automation of production is relatively low. Manual long-term single and repetitive work not only has low production efficiency but also easily causes fatigue of workers, thus causing safety hazards. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic sorting and separation device for long strip fish products, which can replace manual sorting of fish.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] An automatic sorting and separation device for long fish products comprises a conveying device, a sorting device and a spacing device which are sequentially installed on a frame, and a separation device is installed at the tail end of the spacing device.

[0006] The conveying device conveys the long strips of fish; the sorting device sorts the long strips of fish; the spacing device separates each long strip of fish; and the separation device classifies and collects the long strips of fish of different lengths.

[0007] Furthermore, the conveying device includes a driving roller and a driven roller installed at the left and right ends of the frame, a conveyor belt is installed between the driving roller and the driven roller, the driving roller is controlled by a conveying motor installed on the frame, and a conveying limit plate is fixed vertically between the front and rear sides of the frame, the conveying limit plate is located above the conveyor belt, and the distance between the bottom end of the conveying limit plate and the upper surface of the conveyor belt is between the height of one long strip of fish and the height of two long strips of fish. The space between the conveying limit plate and the conveyor belt is used to lay the fish products flat on the conveyor belt.

[0008] Furthermore, there are three conveyor belts installed in parallel between the driving roller and the driven roller. A long strip of iron sheet installed on the frame is provided between adjacent conveyor belts. The long strip of iron sheet is the same height as the conveyor belt, and the width of the long strip of iron sheet is smaller than the width of the long strip of fish being transported.

[0009] Furthermore, in order to prevent the product from falling during the conveying process, the frame is fixedly provided with limit baffles on both sides of the working area of ​​the conveying device.

[0010] Further, the sorting device comprises two motors symmetrically mounted on the outside of the frame, two driving pulleys located on the outside and two passive pulleys located between the driving pulleys, the rotating shafts of the two motors are arranged vertically, the driving pulleys are mounted on the rotating shafts of the motors, and a belt is connected between the driving pulley and the non-adjacent passive pulleys.

[0011] The distance between adjacent active pulleys and passive pulleys is between one and two long fish widths, and the distance between two passive pulleys is less than the width of a long fish.

[0012] The installation height of the driving pulley and the passive pulley is less than the height of a long fish.

[0013] The principle of the sorting device is to control the rotation speed of the two motors so that the rotation speeds of the matching active pulley and passive pulley are different, thereby arranging long strip products with different postures and messy positions in an orderly manner.

[0014] Furthermore, the spacing device includes a plurality of accelerator rods arranged in parallel between the inner and outer sides of the frame and a plurality of spacing motors arranged below the accelerator rods. The ends of the accelerator rods are mounted on the frame through bearings. A plurality of plastic wheels are mounted at both ends of the accelerator rods near the frame. The rotating shaft of the spacing motor is parallel to the accelerator rods.

[0015] A driving gear is installed on the rotating shaft of each split-pitch motor. Several accelerator rods near each driving gear form a group. A driven gear corresponding to the position of the driving gear is installed on each accelerator rod. A chain is installed between the driving gear and the corresponding driven gear.

[0016] The frame is provided with a protective baffle in the area between the plastic wheels on both sides, and the protective baffle is located above the acceleration rod. Vertical limit baffles are fixedly connected to both sides of the frame and both sides of the protective baffle respectively. Adjacent limit baffles are grouped in two to form a transmission channel with the plastic wheels, and the distance between the two limit baffles in each group is between the width of one to two long fish strips.

[0017] In the above-mentioned spacing device, both sides of the protective partition are plastic wheel areas for spacing adjacent products. The width of the transmission channel limits the passage of only one product at a time, thus ensuring normal sorting while spacing.

[0018] Furthermore, each driving gear forms a group with three nearby acceleration rods, and the interval motors are staggeredly distributed below the acceleration rods.

[0019] Furthermore, the separation device includes two separation inclined frames corresponding to the transmission channels respectively, the separation inclined frames are installed on the ground, and long strip separation holes of different sizes are opened at the same position on the two separation inclined frames, and a separation storage box is placed on the ground under each long strip.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention realizes the automatic transportation, sorting, spacing and separation of fish products through the continuous operation of the connected conveying device, sorting device, spacing device and separation device in an assembly line manner. The high degree of automation greatly improves the work efficiency of fish classification and collection, and avoids the safety hazards of long-term manual work.

[0022] 2. The sorting device in the present invention can perform sorting based on the differential principle between pulleys, has a simple structure, and greatly saves operation time and labor costs.

[0023] 3. In the spacing device of the present invention, since the speeds of different groups of acceleration rods controlled by the spacing motor are different, the speed of the long strip products passing through the plastic wheels of the spacing device is gradually increased, so that a certain distance is maintained between the products for spacing.

[0024] 4. The separation device of the present invention adopts inclined gravity separation, and by setting the size of each separation hole, it can separate long strip products of different specifications and lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the purpose, technical solutions and advantages of the present invention will become clearer. It should be noted that the described embodiments are preferred embodiments of the present invention, rather than all embodiments.

[0032] The present invention provides an automatic sorting and separation device for long strip fish, which can automatically sort and separate long strip products, significantly reduce the dependence on manual work and labor costs, and improve production efficiency and automation level.

[0033] Example

[0034] Combination Figure 1 As shown, an automatic sorting and separation device for long strip fish products comprises a conveying device 1, a sorting device 2 and a spacing device 3 which are sequentially mounted on a frame 12, and a separation device 4 is mounted at the tail end of the spacing device 3. The conveying device 1 conveys the long strip fish; the sorting device 2 sorts the long strip fish; the spacing device 3 separates each long strip fish; and the separation device 4 classifies and collects the long strip fish of different lengths.

[0035] like Figure 2 As shown, the conveying device 1 includes a driving roller 5 and a driven roller 7 installed at the left and right ends of a frame 12, a conveyor belt 13 is installed between the driving roller 5 and the driven roller 7, and the driving roller 5 is controlled by a conveying motor 11 installed on the frame. A conveying limit plate 8 is fixed vertically between the front and rear sides of the frame, and the conveying limit plate 8 is located above the conveyor belt 13. The distance between the bottom end of the conveying limit plate 8 and the upper surface of the conveyor belt is between the height of one long strip of fish and the height of two long strips of fish. The fish products are spread on the conveyor belt by using the space between the conveying limit plate 8 and the conveyor belt.

[0036] As a preferred solution, there are three conveyor belts, which are installed in parallel between the driving roller 5 and the driven roller 7. A long iron sheet 6 installed on the frame 12 is provided between adjacent conveyor belts 13. The long iron sheet 6 is at the same height as the conveyor belt 13. The width of the long iron sheet 6 is smaller than the width of the long fish being transported, so as to prevent the fish products from being stranded on the conveyor belt.

[0037] In order to prevent the product from falling off the conveyor belt during transportation, the frame 12 is fixedly provided with limit baffles 9 on both sides of the working area of ​​the conveying device.

[0038] Combination Figure 3As shown, the sorting device 2 includes two motors 14 symmetrically mounted on the outside of the frame, two driving pulleys 17 located on the outside, and two passive pulleys 18 located between the driving pulleys 17, and the passive pulleys 18 are mounted on the frame 12 through passive pulley bearings 15. The rotating shafts 14a of the two motors 14 are vertically arranged, the driving pulleys 17 are mounted on the rotating shafts of the motors 14, and a belt 16 is connected between the driving pulleys 17 and the non-adjacent passive pulleys 18.

[0039] The distance between adjacent active pulleys 17 and passive pulleys 18 is between the width of one to two long strips of fish, and the distance between two passive pulleys 18 is less than the width of a long strip of fish, so that the products can only pass between the active pulley and the passive pulley 18. The installation height of the active pulley 17 and the passive pulley 18 is less than the height of a long strip of fish to ensure that all long strips of fish products can be sorted through the active pulley 17 and the passive pulley 18. A certain distance should be maintained between the belts 16 to ensure that the two sorting ports do not affect each other.

[0040] By controlling the rotation speed of the two motors 14, the rotation speeds of the active pulley and the passive pulley that cooperate with each other are made different, so that the long strip products with different postures and disordered positions can be arranged in an orderly manner.

[0041] Combination Figure 4 and Figure 5 As shown, the spacing device 3 includes a plurality of accelerator rods 25 arranged in parallel between the inner and outer sides of the frame 12 and a plurality of spacing motors 21 arranged below the accelerator rods. The ends of the accelerator rods 25 are mounted on the frame 12 through bearings 26. A plurality of plastic wheels 27 are installed at both ends of the accelerator rods 25 near the frame. The rotating shaft of the spacing motor 21 is parallel to the accelerator rods 25.

[0042] A driving gear 22 is installed on the rotating shaft of each spacing motor 21. Every three accelerator rods 25 near each driving gear 22 form a group. A driven gear 23 corresponding to the position of the driving gear 22 is installed on each group of accelerator rods 25. A chain 24 is installed between the driving gear 22 and the corresponding driven gear 23. The driving gear 22 drives the rotation of the same group of driven gears 23 through the chain 24, so that the rotation speed of each group of three accelerator rods 25 is the same. By controlling the rotation speed of the spacing motor 21, the rotation speed of the accelerator rod 25 is controlled, and the rotation speed of the next group of accelerator rods is made greater than the rotation speed of the previous group of accelerator rods along the transmission direction of the spacing device, so that the distance between products is gradually increased.

[0043] The frame 12 is provided with a protective baffle 20 in the area between the plastic wheels on both sides, and the protective baffle 20 is located above the accelerator rod 25. The two sides of the frame 12 and the two sides of the protective baffle 20 are respectively fixed with vertical limiting baffles 19. Two adjacent limiting baffles 19 are grouped together with the plastic wheels to form a transmission channel 19a, and the distance between the two limiting baffles 19 in each group is between the width of one to two long strips of fish. The width of the transmission channel is only suitable for one long strip of fish to pass through.

[0044] refer to Figure 6 The separation device 4 includes two Figure 4 The separation inclined racks 28 corresponding to the middle transmission channel 19a are installed on the ground, and the same position of the two separation inclined racks 28 is provided with long strip separation holes 29 of different sizes, and a separation storage box 30 is placed on the ground below each long strip 29. The separation holes 29 should be set according to the length requirements of the long strip products to be separated.

[0045] The above is only a description of the preferred embodiment of the present invention, and is not intended to limit the scope of protection of the present invention. Obviously, any technician familiar with the field can easily think of replacements or changes to obtain other embodiments based on the above embodiments, which should all be included in the scope of protection of the present invention.
