Description

Technical Field

[0001] The invention relates to the technical field of strip bag processing equipment, and in particular to a strip bag horizontal material sorting machine. Background Art

[0002] At present, some products on the market are packaged in strips (such as instant coffee, cat strips, pregnancy test kits, and medicines). In the packaging line, the cartoning machine has certain requirements for the quantity and direction of the strips. If there are too many strips, the subsequent stations will not be able to handle them. If the directions of the strips are different, it will greatly increase the difficulty of handling at the subsequent stations, affecting work efficiency.

[0003] Therefore, for the production, processing and packaging lines of strip bags, most of them use manual equipment or semi-automatic equipment, which greatly limits the production efficiency. At the same time, the equipment cost and labor cost are both high, which greatly restricts the development of the enterprise.

[0004] Therefore, there is an urgent need for a device that is specifically designed to sort strip packages (or strip-shaped packaging) products to ensure the one-time delivery quantity of strip packages and the direction of the strip packages during the delivery process, providing convenience for subsequent workstations.

[0039] refer to Figure 1 A horizontal material sorting machine for strip bags according to a preferred embodiment of the present invention will be described in detail below, wherein the horizontal material sorting machine for strip bags includes a frame 10 and a storage bin 20, a loading mechanism 30, a horizontal conveying mechanism 40, a detection and material sorting mechanism 50, a return mechanism 60 and a control cabinet 70 arranged on the frame 10.

[0040] The storage bin 20 is arranged on one side of the length direction of the frame 10, and the storage bin 20 has an opening 201 vertically upward, and the opening 201 is slightly lower than the top surface of the frame 10;

[0041] Among them, combined Figure 2 and Figure 3 The feeding mechanism 30 includes a feeding conveyor frame 31, a feeding belt 32 and a feeding motor 33, wherein the feeding conveyor frame 31 extends obliquely and extends into the storage bin 20 at a relatively low end and extends to the top of the frame 10 at a relatively high end. At the same time, the feeding conveyor frame 31 includes two symmetrically distributed feeding baffles 311 and a feeding connecting frame connected between the two feeding baffles 311, and the feeding belt 32 is wound around the feeding connecting frame in a manner that it can be driven by the feeding motor 33 to rotate in a directional manner, and is arranged side by side on the surface along the movement direction. A material stopper 321 is provided, so that when the feeding motor 33 arranged on the frame 10 drives the feeding belt 32 to rotate in a directional manner through the cooperation of the rotating shaft and the synchronous wheel 331, the synchronous belt 332, the active roller 333 and the driven roller 334, based on the friction between the feeding belt 32 and the material and the blocking effect of the material stopper 321 on the material, the material in the storage bin 20 will be driven to be transported and moved along the feeding belt 32 in a directional manner until it reaches the high end of the feeding mechanism 30, wherein a belt cover 335 is provided on the outer side of the synchronous belt 332;

[0042] Among them, combined Figure 5 and Figure 6 The horizontal conveying mechanism 40 includes a horizontal conveying frame 41, a limiting telescopic member, a conveying belt 42 and a conveying motor 43, wherein the horizontal conveying frame 41 extends horizontally and extends at one end to below the high end of the loading conveying frame 31 to receive the material conveyed by the loading belt 32. In addition, the horizontal conveying frame 41 includes a base frame 411 and a first conveying baffle 412 and a second conveying baffle 413 located on both sides of the base frame 411, and the limiting telescopic member is close to the other end of the horizontal conveying frame 41 and is connected to the outer side wall of the first conveying baffle 412 at the telescopic end, so as to be able to push the The first conveying baffle 412 moves toward or away from the second conveying baffle 413 to change the placement position or placement direction of the material on the conveyor belt 42, thereby forming a pre-adjustment of the material placement direction. Generally, the limit telescopic member is timed to extend and retract, and it is sufficient to ensure that the material between the first conveying baffle 412 and the second conveying baffle 413 can be squeezed and pushed to the side close to the second conveying baffle 413. In addition, the conveyor belt 42 is wound around the base frame 411 in a manner that it can be driven by the conveying motor 43 to rotate in a directional manner to convey the material in a directional manner.

[0043] Among them, combined Figure 1 , Figure 7 and Figure 8 The material detection and sorting mechanism 50 includes a speed-changing roller group 51 extending along the extension direction of the horizontal conveying frame 41, a plurality of photoelectric detection sensors 52 distributed along the extension direction of the speed-changing roller group 51, and a conveying motor 53 driving the speed-changing roller group 51 to rotate, wherein the speed-changing roller group 51 includes a plurality of active rollers 511 distributed at intervals and a driven roller 512 arranged between two adjacent active rollers 511, wherein the rotating end of each of the conveying motors 53 is respectively connected to each of the active rollers 511, wherein the detection end of the photoelectric detection sensor 52 is facing the speed-changing roller group 51, and is used to detect the material on the speed-changing roller group 51, and at the same time, the plurality of photoelectric detection sensors 52 and the plurality of conveying motors 53 are correspondingly arranged, and the distance between two adjacent photoelectric detection sensors 52 is 1 to 2 times the length of the material, such as 1.2 times, 1.4 times, 1.5 times or 1.7 times, etc., so that the gap between the materials can be detected, and then The sensing signal can be transmitted to the control cabinet 70, and then the rotation speed of each of the conveying motors 53 can be controlled by the control cabinet 70 to flexibly adjust the travel speed of the material, or the conveying quantity. It is also worth noting that the control cabinet 70 can synchronously control and adjust the rotation speed of all the conveying motors 53, so as to control the conveying speed of the material as a whole, and can also separately control the rotation speed of each conveying motor 53, so as to locally adjust the conveying speed of the material. In addition, the length of the active roller 511 and the driven roller 512 near the middle of the variable speed roller group 51 is 1 to 1.49 times the width of the material. In this way, a return material gap 501 can be formed at the shorter active roller 511 and the driven roller 512. Under the action of gravity, the material that does not move along the shorter active roller 511 and the driven roller 512 will fall from the return material gap 501, thereby ensuring the travel and placement direction of the material on the material sorting machine, which is convenient for the subsequent workstations to quickly and efficiently process the material.

[0044] Among them, combined Fig. 9 The return mechanism 60 includes a horizontal return frame 61, a return belt 62 and a return motor 63, wherein one end of the horizontal return frame 61 is located below the return gap 501, and the other end thereof extends to above the opening 201 of the storage bin 20. At the same time, the return belt 62 is wound around the horizontal return frame 61 in a manner that it can be driven by the return motor 63 to rotate in a directional manner, thereby being able to transport the material falling from the return gap 501 back to the storage bin 20, forming a circular transportation of the material, realizing the full-process automated material sorting of the material sorting machine, without wasting raw materials, and effectively ensuring high work efficiency.

[0045] Considering that in the early stage, if a large amount of materials are transported at one time, a higher material baffle plate needs to be set up to prevent the materials from spilling. At the same time, each power mechanism needs to pay more kinetic energy, and the subsequent stations of the material sorting machine cannot process a lot of materials at the same time. This will cause two problems: one is the serious waste of resources, and the other is the risk of materials spilling, which is not convenient for the full-process automatic management of the material sorting machine. Therefore, in one embodiment, combined with Figure 2 The loading conveyor frame 31 is provided with a material baffle 312 at the lower end, wherein the material baffle 312 is connected between the two loading baffles 311 and maintains a predetermined distance from the loading belt 32, so that the amount of material taken out of the storage bin 20 at one time can be properly controlled.

[0046] As a preferred embodiment, Figure 4 The feeding mechanism 30 also includes an auxiliary feeding frame 34, an auxiliary feeding belt 35 and an auxiliary feeding motor 36, wherein the auxiliary feeding frame 34 extends obliquely and is perpendicular to the extension direction of the feeding conveying frame 31 and the horizontal conveying frame 41. In addition, the auxiliary feeding frame 34 includes two auxiliary side baffles 341, a bottom baffle 342 connected between the two auxiliary side baffles 341 and located at the lower end, and an auxiliary connecting frame 343 that simultaneously connects the auxiliary side baffles 341 and the bottom baffle 342, wherein one of the auxiliary side baffles 341 is provided with a feed notch 301 suitable for accommodating the feeding conveying frame 31, and the auxiliary feeding belt 35 is wound around the auxiliary connecting frame 343 in a manner that it can be driven by the auxiliary feeding motor 36 to rotate in a directional manner, and the high end of the auxiliary feeding frame 34 extends to above the conveyor belt 42. In this way, the material carried by the feeding belt 32 automatically falls into the auxiliary feeding rack 34, and automatically falls onto the conveyor belt 42 under the action of the auxiliary feeding belt 35, thereby realizing the auxiliary transfer of materials from the storage bin 20 to the horizontal conveying mechanism 40. Since the auxiliary feeding rack 34 is perpendicular to the feeding conveyor rack 31 and the horizontal conveyor rack 41 at the same time, the feeding conveyor rack 31 and the horizontal conveyor rack 41 can extend in the same direction of the length direction of the frame 10, so that the overall structure of the material sorting machine is more compact. More importantly, this can also provide many conveniences for the setting of the return mechanism 60. For example, the overall structure of the return mechanism 60 can be simpler and the cost is lower.

[0047] More preferably, in combination Figure 6, the first conveying baffle 412 includes a primary baffle 4121 and a secondary baffle 4122, and at the same time, the limiting telescopic member includes a primary cylinder 44 and a secondary cylinder 45, which are respectively connected to the outer side walls of the primary baffle 4121 and the secondary baffle 4122, wherein the primary baffle 4121 is composed of a first vertical portion and a first curved portion, and the first curved portion is connected to the rear end of the first vertical portion and gradually extends toward the direction close to the second conveying baffle 413, and at the same time, the primary cylinder 44 is close to the first curved portion, wherein the secondary baffle 4122 includes a second curved portion and a second vertical portion, wherein the second curved portion is close to the outer side of the first curved portion and is opposite to the inclination direction of the first curved portion, and the distance between the second vertical portion and the second conveying baffle is 1 to 2 times the width of the material, so that the material can be squeezed sequentially by the primary baffle 4121 and the secondary baffle 4122, so that the material can finally only flow out from the second vertical portion in a space that can only accommodate the width of a single material. It should be pointed out that this embodiment is different from the situation of squeezing into place at one time, because squeezing into place at one time will violently squeeze the material within approximately the same spatial range, which may damage the material. There is also a situation where more material is piled up in the height direction, which is not conducive to the work of subsequent workstations. There is also a risk of material spilling out of the material sorting machine under the impact force.

[0048] More preferably, in combination Figure 7, the material detection and sorting mechanism 50 also includes a first rejecting mechanism 54 and a material sorting baffle 55 arranged on both sides of the variable speed roller group 51, wherein the first rejecting mechanism 54 includes a first rejecting motor 541, a first rejecting shaft 542 and a first rejecting blade 544, wherein the first rejecting motor 541 is fixedly installed on the material sorting baffle 55 close to the inner side, close to the front end of the return material gap 501, and is coaxially connected to the first rejecting shaft 542 through the output end, wherein the first rejecting blade 544 is evenly sleeved on the first rejecting shaft 542, and the distance between the first rejecting blade 544 and the variable speed roller group 51 in the height direction is 1.1 to 1.9 times the thickness of the material, so that the first rejecting shaft 542 can be driven to rotate by the first rejecting motor 541, thereby driving the first rejecting blade 544 to rotate, and the material near the upper The materials are rejected and knocked down to the return material gap 501, and then circulated into the storage bin 20 through the return material gap 501. In this way, when the materials on the variable speed roller group 51 are conveyed to the first rejection blade 544, the first rejection blade 544 can only allow a layer of materials close to the variable speed roller group 51, or the bottom layer of materials to be conveyed to the downstream station. In this way, on the basis of limiting the conveying speed (provided by the variable speed roller group 51) and limiting the conveying width range, or the amount of materials in the width direction (provided by the first baffle 4121 and the second baffle 4122) in the previous process, the amount of conveyed materials can be restricted again in the height direction, so that the subsequent stations can obtain single-piece materials that are basically conveyed at a uniform speed and have a roughly determined placement direction, and the material sorting efficiency and quality are significantly improved.

[0049] More preferably, in combination Figure 7 The first rejecting mechanism 54 also includes a stopper 543, wherein the stopper 543 is installed on the material sorting baffle 55 close to the inner side, is located above the return material notch 501, and is located on the rear side of the first rejecting blade. At the same time, the stopper 543 is provided with an arc structure, wherein the arc structure gradually extends toward the rear side from one side close to the material sorting baffle 55 to the other side away from the material sorting baffle 55, thereby being able to block part of the material blown away by the first rejecting blade to a certain extent, avoiding the material from running around, making the workstation tidier, and avoiding the waste of raw materials.

[0050] More preferably, in combination Figure 7The material detection and sorting mechanism 50 also includes a second rejecting mechanism 56, wherein the second rejecting mechanism 56 includes a second rejecting motor 561, a second rejecting shaft 562 and a second rejecting brush 563, wherein the second rejecting motor 561 is installed on the material sorting baffle 55 close to the inner side, and close to the rear end of the return material gap 501, and is coaxially connected to the second rejecting shaft 562 through the output end, and at the same time, the second rejecting brush 563 is sleeved on the second rejecting shaft 562, and maintains a predetermined gap with the speed change roller group 51 and the material sorting baffle 55 close to the inner side at the return material gap 501, so that only one piece of material is allowed to pass on the speed change roller group 51 in the width direction. Through the continuous rolling of the second rejecting brush 563, the material flowing through the second rejecting brush 563 will be rolled to the return material gap 501. At the same time, for the material close to the inside, the continuous rolling action of the second rejecting brush 563 will make it closer to the inner material sorting baffle 55, that is, the placement direction of the material is more consistent, extending toward the extension direction of the variable speed roller group 51, thereby further improving the material sorting effect and quality of the material sorting machine.

[0051] Preferably, combined Fig. 9 The material sorting baffle 55 close to the outside is connected to the horizontal reflux rack 61 at the bottom, so that the material sorting baffle 55 close to the outside forms a limit for the material on the outside of the variable speed roller group 51 and the horizontal reflux rack 61 at the same time, saving costs.

[0052] More preferably, in combination Figure 7 and Fig.10The horizontal strip bag sorting machine also includes an inclination adjustment mechanism, wherein the inclination adjustment mechanism includes a rotating shaft 81, a driving shaft 82 and a plurality of eccentric wheels 83 sleeved on the driving shaft 82, wherein the rotating shaft 81 is also equipped with a hand wheel 811 or a motor at the front end to realize manual rotation or automatic rotation of the rotating shaft 81, wherein the extension direction of the rotating shaft 81 is perpendicular to the extension direction of the speed change roller group 51, and is generally located below the speed change roller group 51, and at the same time, the rotating shaft 81 is connected to the end of the driving shaft 82 through a meshing bevel gear 812 at the end to realize a rotational connection relationship between the driving shaft 82 and the end of the detection and sorting mechanism 50, wherein the driving shaft 82 has the same extension direction as the speed change roller group 51, is located at the rear side of the detection and sorting mechanism 50, and abuts against the fixed plate 57 on the rear side of the detection and sorting mechanism 50 through the eccentric wheel 83, and at the same time, the detection and sorting mechanism 50 is hinged to the frame 10 through the fixed plate 57, wherein the eccentric wheel 83 is close to the lower end of the hinge of the fixed plate 57. When the rotating shaft 81 rotates, under the meshing action of the two bevel gears 812, the driving shaft 82 on the rear side drives the multiple eccentric wheels 83 to rotate synchronously. Based on the abutment relationship between the eccentric wheel 83 and the fixed plate 57, the hinge relationship between the detection and material sorting mechanism 50 and the frame 10, and the lever principle, the detection and material sorting mechanism 50 is driven to rotate directional with the hinge shaft 571 in the fixed plate 57 as the axis, so that the speed change roller group 51 can be tilted at a certain angle, thereby ensuring that the material is conveyed and moved close to the inner material sorting baffle 55, thereby improving the material conveying efficiency. At the same time, it also ensures that the material is close to the predetermined placement direction due to the action of gravity due to the proximity to the inner material sorting baffle 55. The predetermined placement direction is the placement direction that the first baffle 4121 and the second baffle 4122 want the material to maintain, and it is also the placement direction that the second removal brush 563 wants the material to maintain. Generally, the speed-changing roller set 51 is higher on the outside and lower on the inside, that is, the end close to the outside is higher than the end close to the inside, and generally maintains an angle of 3°-7° relative to the horizontal direction.

[0053] Further preferably, the material storage bin 20, the feeding structure 30, the horizontal conveying mechanism 40, the material detection and sorting mechanism 50 and the material return mechanism 60 are all arranged in a mirror-symmetrical manner on both sides of the length direction of the frame 10, so that double stations can operate simultaneously, greatly reducing the site space occupied by the material sorting machine and improving work efficiency.
