Description

Technical Field

[0001] The utility model relates to an automatic counting bagged material conveying device, belonging to the technical field of material conveying equipment. Background Art

[0002] The loading and unloading work in the feed processing process mainly includes unloading the bagged raw materials from the transport truck and sending them to the warehouse, and loading the bagged feed products from the warehouse into the transport truck, etc. In the process of loading and unloading bagged materials, conveyor belt equipment (such as belt conveyor) is one of the indispensable equipment. The use of conveyor belt equipment can effectively improve labor efficiency and reduce labor intensity. However, the existing conveyor belt equipment has a relatively single function. In the process of conveying bagged materials, it is usually necessary to manually count the number of bagged materials transported, which is prone to inaccurate counting and affects work efficiency. In addition, the control switch of the conveyor belt equipment is usually installed at one end of the equipment (mostly installed at the head end of the conveyor belt equipment). In the process of loading and unloading bagged materials, when the equipment needs to be shut down due to reasons at the conveying end, the staff at the conveying head end often fail to shut down the equipment in time due to the delay in receiving the shutdown information from the conveying end, which poses a great work safety hazard.

[0034] The beneficial effects of the utility model are:

[0035] (1) Due to the installation of a photoelectric counter, the quantity information of the conveyed materials can be automatically obtained during the conveying process of the bagged materials, which is conducive to saving manpower or reducing labor intensity, and reducing or avoiding human errors;

[0036] (2) Since a counter photoelectric switch is provided, the photoelectric counter can be automatically started to count during the conveying process of the bagged materials (before being conveyed to the location of the photoelectric counter), which simplifies the counting operation process and reduces the complexity of the operation;

[0037] (3) Due to the provision of a bagged material posture adjustment mechanism, the posture of the bagged material can be automatically adjusted before the bagged material is transported to the location of the photoelectric counter, so that the bagged material is automatically arranged in an orderly manner along the trough structure with a gradually decreasing width (the bagged material gradually moves inward under the obstruction and guidance of the guardrail until its lateral span adapts to the width of the outlet end of the trough structure), ensuring that the number of bagged materials transported to the location of the photoelectric counter at the same time is only one and the posture is uniform, thereby ensuring the accuracy of the photoelectric counter counting and avoiding the photoelectric counter counting errors caused by two or more bagged materials being horizontally attached together during the transportation process;

[0038] (4) The vertical roller of the bag material posture adjustment mechanism is set. When the bag materials (with different postures) placed on the conveyor belt are transported to the bag material posture adjustment mechanism (between the two guardrails) and contact the vertical roller, the vertical roller rotates under the push of the bag materials, which can significantly reduce the friction between the bag materials and the guardrails. It not only reduces the resistance and avoids the occurrence of jamming, but also avoids the damage of the bag materials caused by friction. In addition, the rotation of the vertical roller helps to quickly adjust the conveying posture of the bag materials;

[0039] (5) Due to the provision of a bagged material deceleration and buffering structure, when the bagged material is output from the bagged material posture adjustment mechanism (from the groove structure), the bagged material deceleration and buffering structure will form a certain resistance to the bagged material, decelerate and buffer the bagged material, and ensure that there is a certain interval between the bagged materials output continuously from the bagged material posture adjustment mechanism, thereby ensuring the accuracy of the photoelectric counter counting and avoiding the photoelectric counter counting errors caused by two or more bagged materials sticking together in the transmission direction during the conveying process;

[0040] (6) The setting of the crossbar of the bagged material posture adjustment mechanism. When the bagged materials entering the bagged material posture adjustment mechanism overlap or stick together vertically, the crossbar can push down the bagged materials overlapping or sticking on the top, so as to ensure that the number of bagged materials entering or exiting the bagged material posture adjustment mechanism at the same time is only one, thereby ensuring the accuracy of the photoelectric counter counting and avoiding the photoelectric counter counting errors caused by two or more bagged materials overlapping or sticking together vertically during the conveying process;

[0041] (7) Since the bagged material upright detection sensor and the bagged material laying-down mechanism are provided, the bagged material upright detection sensor can detect whether the bagged materials on the conveyor belt are upright. When the bagged materials are upright, the control signal is output to control the bagged material laying-down mechanism to lay down the upright bagged materials, so that the bagged materials entering the bagged material posture adjustment mechanism are all in a flat posture, thereby ensuring the effect of the bagged material posture adjustment mechanism on the bagged material posture adjustment and ensuring the accuracy of the photoelectric counter counting;

[0042] (8) Since the distance between the two guardrails of the bag material posture adjustment mechanism can be adjusted, the vertical distance between each detection component, each bag material adjustment component and the conveyor belt can also be adjusted, so that the above components or mechanisms can flexibly adjust the height or distance according to the size of the bag material, so that the conveying device can adapt to the conveying and counting of bag materials of various sizes, and ensure the accuracy of counting, and has a wide range of applications;

[0043] (9) Since the control switch of the belt conveyor adopts a double switch or a pull-rope switch, when an unexpected situation occurs during the transportation of bagged materials, the belt conveyor can be stopped at the end of the conveyor belt (or the rear end) or at any position on the conveying path. After the unexpected situation is eliminated, the belt conveyor can also be started at the end of the conveyor belt or at any position on the conveying path. This is convenient for control and can ensure the safety of material transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Figure 3 It is a top view schematic diagram of an implementation mode of the bagged material posture adjustment mechanism of the utility model. DETAILED DESCRIPTION

[0047] All directional indications in the implementation modes of the present invention (such as up, down, front, back, left, right, first, last, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings), and do not constitute a limitation on the actual use direction. If the specific posture changes, the directional indication will also change accordingly.

[0048] See also Figure 1 , Figure 2 and Figure 3 The utility model discloses an automatic counting bagged material conveying device, which adopts a belt conveyor as the conveying equipment for bagged materials. The belt conveyor is provided with a conveyor belt 1, and the width of the conveyor belt is usually greater than the length of the bagged materials 2 (the bagged materials are usually irregular rectangular parallelepiped, and the width of the conveyor belt is greater than the length of the bagged materials, which is also greater than the width and height of the bagged materials at the same time), so as to ensure that the bagged materials can be smoothly conveyed no matter in what posture they are placed on the conveyor belt. A photoelectric counter 3 is provided on the bagged material conveying path of the conveyor belt for recording the number of bagged materials conveyed by the conveyor belt. The photoelectric counter is provided with a counter photoelectric switch 4 for controlling its startup, and the counter photoelectric switch is located along the conveyor belt on the bagged material conveying path in the material incoming direction of the photoelectric counter (located in front of the photoelectric counter). During the conveying process of bagged materials (before conveying to the location of the photoelectric counter), when the bagged materials are conveyed to the location of the counter photoelectric switch, the counter photoelectric switch detects / sensing the bagged materials and sends a control signal to control the photoelectric counter to automatically start counting. When the photoelectric counter or the counter photoelectric switch does not detect / sensing the bagged materials for a long time (the time threshold for not detecting / sensing the bagged materials can be preset for the photoelectric counter or the counter photoelectric switch according to the prior art, which is used to automatically shut down the photoelectric counter), the photoelectric counter automatically shuts down. The setting of the counter photoelectric switch realizes the unmanned automatic start or automatic start and shut down of the photoelectric counter, simplifies the operation process of counting work, and reduces the complexity of operation.

[0049] The photoelectric counter and the counter photoelectric switch are usually arranged on one side of the conveyor belt (the side along the transmission direction of the conveyor belt), and can be fixedly mounted on the frame of the belt conveyor through respective fixing brackets.

[0050] The vertical distance between the photoelectric counter and the counter photoelectric switch (referring to the photoelectric elements of the two, such as the transmitter and the receiver) and the upper surface of the conveyor belt is less than the height of the bagged material and greater than zero, so that no matter in what posture the bagged material travels to the position where the photoelectric counter and the counter photoelectric switch are located, the photoelectric counter and the counter photoelectric switch (referring to the photoelectric elements of the two) can detect / sensing the bagged material to ensure the accuracy of the counting.

[0051] The fixed bracket of the photoelectric counter and the counter photoelectric switch preferably adopts a height-adjustable bracket, such as any suitable telescopic bracket in the prior art, so that the vertical spacing between the photoelectric counter and the counter photoelectric switch and the conveyor belt can be adjusted, which is suitable for detecting and counting bagged materials of different sizes.

[0052] The photoelectric counter is usually arranged in the middle or rear part of the conveyor belt along the transmission direction (or conveying direction) of the conveyor belt. A distance is usually left between the counter photoelectric switch and the photoelectric counter to allow sufficient control reaction time.

[0053] The photoelectric counter may be an infrared counter or other suitable types of photoelectric counters.

[0054] The photoelectric counter is preferably provided with a display screen for visually displaying the counting results.

[0055] The conveyor belt is preferably provided with a bag material posture adjustment mechanism 5 for adjusting the traveling posture of the bag material during the conveying process. The bag material posture adjustment mechanism is located along the conveyor belt in the material incoming direction of the photoelectric counter (located in front of the photoelectric counter) and has a spacing between the bag material posture adjustment mechanism and the photoelectric counter. Usually, the bag material posture adjustment mechanism is located along the conveyor belt in the material incoming direction of the counter photoelectric switch (located in front of the counter photoelectric switch).

[0056] The bagged material posture adjustment mechanism preferably includes two left and right guardrails symmetrically arranged on the conveyor belt, the two guardrails and the conveyor belt form a trough structure, the width of the trough structure gradually decreases along the conveying direction of the conveyor belt (gradually decreases from front to back), the inlet end width of the trough structure is the same as the width of the conveyor belt, and the outlet end width of the trough structure is the same as the width of the bagged material (or slightly larger than the width of the bagged material), so that when the bagged material passes through the bagged material posture adjustment mechanism, the two guardrails can adjust the traveling posture of the bagged material, so that the length direction of the bagged material is the same as the conveying direction of the conveyor belt, and the bagged material is automatically arranged in an orderly manner along the trough structure with a gradually decreasing width without manual intervention, ensuring that the number of bagged materials transported to the position of the photoelectric counter at the same time is only one and the posture is unified, thereby ensuring the accuracy of the photoelectric counter counting and avoiding the photoelectric counter counting errors caused by two or more bagged materials being horizontally attached together during the conveying process.

[0057] The inner side of the guardrail of the trough structure is preferably composed of a plurality of vertical rollers 51 arranged together, and the vertical rollers are rotatably mounted on corresponding mounting frames 52. The vertical rollers on the same guardrail are preferably arranged on the same vertical plane and arranged regularly and densely, and a gap is left between adjacent vertical rollers to allow relative rotation, and the width of the gap between any two adjacent vertical rollers is preferably the same. The setting of the gap can avoid the friction between the adjacent vertical rollers when rotating, and can also reduce the number of the vertical rollers used, thereby reducing costs.

[0058] The main part of the mounting frame can be located on the outside of the corresponding vertical roller, and is provided with a plurality of pairs of upper and lower corresponding mounting seats 53 extending inward, and the upper and lower axial extensions of the vertical roller (the central shaft extending from the upper and lower ends) are rotatably mounted on the same pair of upper and lower corresponding mounting seats through corresponding mounting bearings, or the upper and lower ends of the vertical roller are rotatably mounted on the central shaft fixedly connected to the same pair of upper and lower corresponding mounting seats at both ends through corresponding mounting bearings, thereby allowing the vertical roller to rotate freely around the vertical axis. When the bagged materials scattered (in different postures) on the conveyor belt pass through the bagged material posture adjustment mechanism (referring to the space between the two guardrails), they gradually move inward under the obstruction and guidance of the guardrails until their lateral span adapts to the width of the outlet end of the trough structure (that is, the length direction of the bagged materials is the same as the conveying direction of the conveyor belt). The vertical rollers rotate under the push of the bagged materials, which can significantly reduce the friction between the bagged materials and the guardrails, not only reducing the resistance and avoiding the occurrence of jamming, but also avoiding the damage of the bagged materials due to friction. The rotation of the vertical rollers also helps to quickly adjust the conveying posture of the bagged materials.

[0059] The mounting frame can be connected to the frame of the belt conveyor or fixed on the ground. When the mounting frame is connected to the frame of the belt conveyor, the mounting frame is rotatably connected to the frame of the belt conveyor and can be positioned after relative rotation. The rotatable connection method can adopt any suitable rotatable connection method under the existing technology, for example, connection through a turntable or connection through a rotating shaft. With such a configuration, the width between the two guardrails can be freely adjusted according to the size of the bagged material, that is, the width of the outlet end of the trough structure can be adjusted to be suitable for posture adjustment of bagged materials of different sizes. When the mounting frame is fixed on the ground, the width of the outlet end of the trough structure can be adjusted by first releasing the fixed connection between the mounting frame and the ground, adjusting the inclination angle of the guardrail, and then re-fixing the mounting frame to the ground.

[0060] The vertical height of the guardrail (including the vertical roller) relative to the conveyor belt is preferably the same as or similar to the height of the bagged material.

[0061] The outlet end of the trough structure is preferably provided with a bagged material deceleration and buffering structure 6, which includes vertical flexible baffles respectively arranged at the ends (or rear ends) of the two guardrails, and the baffles are arranged inwardly along the conveying direction of the conveyor belt, and a spacing is left between the ends (or rear ends) of the two baffles. The spacing between the ends of the two baffles is preferably greater than 4 / 5 of the width of the bagged material and less than the width of the bagged material. In this way, when the bagged material is output from the bagged material posture adjustment mechanism (from the trough structure), the two baffles will form a certain resistance to the bagged material (the movement of the bagged material will push the two baffles outward, thereby generating a certain travel resistance), decelerate and buffer the bagged material (after the bagged material passes, the two baffles automatically reset), and ensure that there is a certain interval between the bagged materials continuously output from the bagged material posture adjustment mechanism, thereby ensuring the accuracy of the photoelectric counter counting, and avoiding the photoelectric counter counting errors caused by two or more bagged materials being attached together in the transmission direction during the conveying process.

[0062] The blocking piece can be a plastic piece or a rubber piece.

[0063] The bagged material posture adjustment mechanism is preferably also provided with a cross bar 7, which is located above the conveyor belt and perpendicular to the conveyor belt, and is installed on a corresponding cross bar bracket. The distance between the cross bar and the upper surface of the conveyor belt is greater than the height of the bagged material and less than 1.5 times the height of the bagged material, and the distance between the cross bar and the upper surface of the conveyor belt is preferably less than 1.2 times the height of the bagged material. With such a configuration, when the bagged materials entering the bagged material posture adjustment mechanism are vertically overlapped or attached, the cross bar can push down the bagged materials that are overlapped or attached above, ensuring that the number of bagged materials entering or outputting the bagged material posture adjustment mechanism at the same time is only one, thereby ensuring the accuracy of the photoelectric counter counting and avoiding the photoelectric counter counting errors caused by two or more bagged materials being vertically overlapped or attached together during the conveying process.

[0064] The cross bar is preferably arranged at the front end of the bag material posture adjustment mechanism. Since the width of the front end of the bag material posture adjustment mechanism is larger than the width of the rear end, it can ensure that the bag material that is vertically overlapped or attached to the top and is knocked off by the cross bar can fall onto the conveyor belt and smoothly enter the trough structure, avoiding falling outside the trough structure.

[0065] The cross bar and the cross bar bracket are preferably rotatably connected. When the cross bar pushes down the bagged materials, it can rotate relative to the cross bar bracket under the thrust of the bagged materials, so as to avoid jamming or damage to the bagged materials when the bagged materials are pushed down.

[0066] The cross bar bracket can be connected to the frame of the belt conveyor. The cross bar bracket is preferably provided with a height adjustment mechanism. The height adjustment mechanism can adopt any suitable height adjustment mechanism under the existing technology, such as a telescopic rod mechanism, and a telescopic cylinder mechanism, so that the vertical height of the cross bar relative to the conveyor belt can be adjusted to be suitable for adjustment operations on bagged materials of different sizes.

[0067] The automatic counting bagged material conveying device is preferably provided with a bagged material standing detection sensor 8 for detecting whether the bagged material is standing upright during the conveying process. The bagged material standing detection sensor is located along the conveyor belt in the material incoming direction of the bagged material posture adjustment mechanism (located in front of the bagged material posture adjustment mechanism), and has a spacing between it and the bagged material posture adjustment mechanism. The bagged material standing detection sensor includes a first standing detection photoelectric switch 81 and a second standing detection photoelectric switch 82. The detection light beams of the first standing detection photoelectric switch and the second standing detection photoelectric switch are both transverse (horizontally and perpendicular to the conveying direction of the conveyor belt) light beams, and have the same position in the longitudinal direction (the conveying direction of the conveyor belt), so as to facilitate the detection of the placement state of the bagged material passing through the two standing detection photoelectric switches on the conveyor belt. The vertical spacing between the first standing detection photoelectric switch and the conveyor belt is less than the width of the bagged material and greater than the height of the bagged material, and the vertical spacing between the second standing detection photoelectric switch and the conveyor belt is less than the height of the bagged material and greater than zero. So that when an upright bagged material (whether it is upright along the length direction or along the width direction) passes the position where the two upright detection photoelectric switches are located, the first upright detection photoelectric switch and the second upright detection photoelectric switch can both detect changes in light signals; when a bagged material placed flat on the conveyor belt passes the position where the two upright detection photoelectric switches are located, the second upright detection photoelectric switch can detect changes in light signals, while the first upright detection photoelectric switch cannot detect changes in light signals, thereby determining whether the bagged material passing the position where the two upright detection photoelectric switches are located is in an upright state.

[0068] The erection detection sensor is usually arranged on one side of the conveyor belt (the side along the transmission direction of the conveyor belt), and can be fixedly installed on the frame of the belt conveyor through a corresponding bracket. The vertical spacing between the erection detection sensor (including the first erection detection photoelectric switch and the second erection detection photoelectric switch) and the conveyor belt is preferably adjustable, which can be adjusted by providing a height adjustment mechanism on the mounting bracket, or by sliding the erection detection sensor up and down on its mounting bracket, so that the vertical height of the first erection detection photoelectric switch and the second erection detection photoelectric switch relative to the conveyor belt can be flexibly adjusted according to the size of the bagged material, so as to be suitable for judging whether bagged materials of different sizes are transported in an upright state.

[0069] The automatic counting bagged material conveying device is also preferably provided with an upright bagged material laying down mechanism 9, which is located between the bagged material upright detection sensor and the bagged material posture adjustment mechanism, and is used to lay down (lay flat) the bagged material conveyed in an upright state. The upright bagged material laying down mechanism can adopt a manipulator that can grab the upright bagged material and lay it down, and the manipulator grabs the bagged material conveyed in an upright state on the conveyor belt and lays it down. The upright bagged material laying-down mechanism may also adopt a push plate mechanism, which is arranged on one side of the conveyor belt and above the conveyor belt, and is provided with a push plate and an air cylinder or oil cylinder for driving the push plate to move, and the push plate is installed at the outer end of the piston rod of the air cylinder or oil cylinder, and the moving direction of the piston rod is horizontal and perpendicular to the conveyor belt, and its moving trajectory corresponds to the middle or upper part of the upright bagged material (the vertical distance between the moving trajectory and the upper surface of the conveyor belt is less than the width of the bagged material, usually not more than 3 / 4 of the width of the bagged material). When the bagged material being transported in an upright state moves to the position of the push plate mechanism, the piston rod of the air cylinder or oil cylinder drives the push plate to move, pushes down and lays the upright bagged material flat, and then the air cylinder or oil cylinder drives the push plate to reset. At a position of the belt conveyor corresponding to the setting position of the push plate mechanism, an upright baffle plate may be provided on one side of the conveyor belt (the side opposite to the side where the push plate mechanism is located) to prevent the bagged materials from falling off the conveyor belt when the push plate pushes down the bagged materials being conveyed in an upright state.

[0070] The signal output of the bagged material upright detection sensor is connected to the control end of the upright bagged material laying mechanism, so as to control the action of the upright bagged material laying mechanism according to the judgment result of the bagged material upright detection sensor. When the bagged material upright detection sensor controls the action of the upright bagged material laying mechanism, the existing technology can be used to appropriately delay the conveying speed of the conveyor belt and the distance between the bagged material upright detection sensor and the upright bagged material laying mechanism, so as to ensure that the upright bagged material laying mechanism can accurately lay down the bagged materials conveyed in an upright state.

[0071] When the upright bagged material laying-down mechanism adopts a push plate mechanism, the push plate mechanism can be installed on the frame of the belt conveyor through a corresponding mounting frame, or can be fixed on the ground. The push plate mechanism is preferably provided with a height adjustment mechanism so that the vertical height relative to the conveyor belt can be flexibly adjusted according to the size of the bagged material, so as to be suitable for operating bagged materials of different sizes.

[0072] The control switch of the belt conveyor adopts a double switch, and the two switches of the double switch are respectively arranged at the head end and the end of the conveyor belt, or the control switch of the belt conveyor adopts a pull rope switch, and the pull rope of the pull rope switch is arranged along the extension direction of the conveyor belt, and the two ends of the pull rope are respectively located at the head end and the end of the conveyor belt. In this way, when an unexpected situation occurs during the conveying of bagged materials, the belt conveyor can be controlled to stop at the end (or rear end) of the conveyor belt or at any position on the conveying path. After the unexpected situation is eliminated, the belt conveyor can also be controlled to start at the end of the conveyor belt or at any position on the conveying path, which is convenient for control and can ensure the safety of material transportation.

[0073] The conveying device is not only suitable for conveying and counting bagged materials, but also suitable for conveying and counting boxed materials or other objects with the same or substantially the same appearance.

[0074] Unless otherwise specified or one preferred or optional technical means is a further limitation of another technical means, all preferred and optional technical means disclosed in the present utility model can be arbitrarily combined to form several different technical solutions.
