Sorting and pushing device for conveyor

Abstract

The utility model relates to a sorting and pushing device for a conveyor, which comprises a pushing mechanism arranged on one side of a temporary retention area of the conveyor and capable of selectively pushing a plurality of conveyed objects which are gathered in the temporary retention area of the conveyor and are linearly arranged; the movable guardrail mechanism is arranged on the other side of the temporary retention area of the conveyor; and the control module is electrically connected with the pushing mechanism and the movable guardrail mechanism. The control module not only can control the pushing mechanism to select one or more of the conveyed objects in the temporary retention area as selected objects and push the selected objects away from the conveyor, but also can control the movable guardrail mechanism to be converted into a local release state from a complete blocking state for preventing the conveyed objects from falling off from one side, far away from the pushing mechanism, of the conveyor; therefore, the movable guardrail mechanism only allows the selected object to be passively separated from the conveyor. The sorting and pushing device not only can smoothly push the conveyed object out of the conveyor, but also can effectively prevent the conveyed object from being accidentally separated from the conveyor due to out of control.

Description

Technical Field

[0001] The embodiments of the utility model relate to the field of material packaging, and more specifically, relate to a picking and pushing device for a conveyor. Background Art

[0002] In the field of material packaging, a picking and pushing device is usually used as an auxiliary device of a conveyor, which can temporarily stop multiple conveyed objects on the conveyor for picking and pushing, so as to realize operations such as material transfer or material sorting. The existing picking and pushing device usually consists of a pushing mechanism arranged on the side of the conveyor and a control module electrically connected to the pushing mechanism. The control module can control the pushing mechanism to select one or more conveyed objects passing through it and push it or them out of the conveyor.

[0003] However, the existing picking and pushing devices have the following defects: when the conveyor transports the conveyed objects, the conveyed objects tend to accidentally fall off the side of the conveyor away from the pushing mechanism; when the pushing mechanism pushes one or more selected conveyed objects away from the conveyor, the unselected conveyed objects are likely to accidentally leave the conveyor along with the selected conveyed objects, thereby affecting the normal progress of operations such as material transfer or material sorting. Utility Model Content

[0004] In order to solve one or more of the technical problems mentioned above, the utility model provides a picking and pushing device for a conveyor, which can not only push the conveyed objects out of the conveyor smoothly, but also effectively prevent the conveyed objects from accidentally leaving the conveyor due to loss of control.

[0005] The utility model provides a picking and pushing device for a conveyor, which includes: a pushing mechanism, which is arranged on one side of the temporary retention area of ​​the conveyor and can selectively push a plurality of conveyed objects gathered in the temporary retention area of ​​the conveyor and arranged linearly; a movable guardrail mechanism, which is arranged on the other side of the temporary retention area of ​​the conveyor and has a partial release state and a complete blocking state; a control module, which is electrically connected to the pushing mechanism and the movable guardrail mechanism. Wherein, the control module is configured to, on the one hand, control the pushing mechanism to select one or more conveyed objects from the conveyed objects staying in the temporary retention area as selected objects and push them away from the conveyor, and on the other hand, control the movable guardrail mechanism to convert from a complete blocking state that prevents each conveyed object from falling off from the side of the conveyor away from the pushing mechanism to a partial release state, so as to ensure that the movable guardrail mechanism only allows the selected objects to passively leave the conveyor.

[0006] The picking and pushing device provided above includes, in addition to the pushing mechanism and the control module, a movable guardrail mechanism electrically connected to the control module. The movable guardrail mechanism can not only be controlled by the control module to prevent the objects being sent from falling from the side of the conveyor away from the pushing mechanism when the pushing mechanism does not push the objects, but can also be controlled by the control module to avoid by switching the state when the pushing mechanism pushes the objects, so as to ensure that each selected object can be pushed away from the conveyor smoothly, and at the same time prevent the unselected objects from leaving the conveyor along with the selected objects, effectively ensuring the normal operation of operations such as material transfer or material sorting. In other words, the picking and pushing device can not only push the objects being sent out of the conveyor smoothly, but also effectively prevent the objects being sent from accidentally leaving the conveyor due to loss of control.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0018] Figure 1 The present invention shows a first embodiment of a picking and pushing device for a conveyor. Figure 4 The present invention shows a second embodiment of a picking and pushing device for a conveyor. Figure 6 The figure shows a three-dimensional view of the use state of the picking and pushing device for the conveyor according to the third embodiment of the utility model. Figure 1 , Figure 4 and Figure 6 As shown, the first to third embodiments of the present invention all provide a picking and pushing device 100 for a conveyor 200. The picking and pushing device 100 is mainly used as an auxiliary device of the conveyor 200, which can pick and push a plurality of conveyed objects 300 temporarily staying on the conveyor 200, so as to realize operations such as material transfer or material sorting.

[0019] In a specific application scenario, the conveyor 200 and its picking and pushing device 100 are used in the packaging system of raw ingredients such as fruits, vegetables, seafood, etc., to assist its combined counterweight subsystem and / or grade sorting subsystem to complete the corresponding functions. Specifically, the conveyor 200 may include a conveyor body 200a with a temporary retention area and a blocking mechanism 200b provided on the conveyor body 200a and used to intercept the material tray and the raw ingredients carried by it. Among them, the conveyor body 200a can be selected as a conveying device including a belt conveyor or a roller conveyor suitable for conveying the material tray containing raw ingredients. The blocking mechanism 200b can be selected as a fixed blocking structure or a movable blocking structure, such as the blocking mechanism 200b is selected as a rotating baffle driven by a power source such as a cylinder or a control motor and rotatably provided on the conveyor body 200a. The temporary retention area starts at the location of the blocking mechanism 200b and extends to the input end of the conveyor body 200a. The temporary storage area is used to gather the trays containing raw food and arrange them linearly when the blocking mechanism 200b is in the intercepting state. The length of the temporary storage area can be determined according to the number of trays to be gathered, and the maximum value can be the same or similar to the length of the conveyor body 200a. Figure 1 or Figure 4 ), the blocking mechanism 200b is in the intercepting state, the rotating baffle can intercept the trays containing raw food and cause the trays containing raw food to begin to assemble and arrange into a linear array in the temporary storage area, so as to ensure that the picking and pushing device 100 can more accurately pick and push the multiple objects 300 to be delivered from the temporary storage area. When the rotating baffle is driven to a position parallel to the conveying direction of the conveyor 200, the blocking mechanism 200b is in the releasing state, and the trays containing raw food are unimpededly separated from the conveyor 200 under the conveying action of the conveyor 200.

[0020] In the first to third embodiments, the picking and pushing device 100 includes a pushing mechanism 1 which is arranged at one side of the temporary holding area of ​​the conveyor 200 and can selectively push a plurality of conveyed objects gathered in the temporary holding area of ​​the conveyor 200, a movable guardrail mechanism 2 which is arranged at the other side of the temporary holding area of ​​the conveyor 200 and has a partial release state and a complete blocking state, and a control module (not shown) which is electrically connected to the pushing mechanism 1 and the movable guardrail mechanism 2. The control module is configured to, on the one hand, control the pushing mechanism 1 to select one or more conveyed objects 300 staying in the temporary holding area as selected objects and push them away from the conveyor 200, and on the other hand, control the movable guardrail mechanism 2 to convert from a complete blocking state that prevents each conveyed object 300 from falling off from the side of the conveyor 200 away from the pushing mechanism 1 to a partial release state, so as to ensure that the movable guardrail mechanism 2 only allows the selected object to passively leave the conveyor 200.

[0021] Compared with the prior art, the aforementioned picking and pushing device 100, in addition to the pushing mechanism 1 and the control module, also includes a movable guardrail mechanism 2 electrically connected to the control module. The movable guardrail mechanism 2 can not only be controlled by the control module to prevent the conveyed object 300 from falling from the side of the conveyor 200 away from the pushing mechanism 1 when the pushing mechanism 1 does not push the conveyed object 300, but can also be controlled by the control module to implement avoidance by switching the state when the pushing mechanism 1 pushes the conveyed object 300, so as to ensure that each selected conveyed object 300 can be smoothly pushed away from the conveyor 200, and at the same time, it can also prevent the unselected conveyed objects 300 from leaving the conveyor 200 together with the selected conveyed objects 300, thereby effectively ensuring the normal progress of operations such as material transfer or material sorting.

[0022] As for the specific implementation method, the aforementioned control module of the present invention can be implemented in various suitable ways. For example, the control module can be implemented by a general-purpose processor ("CPU") or a dedicated processor, or a combination of the two. In some scenarios, the control module of the present invention can also be implemented by a programmable logic controller (Programmable Logic Controller, "PLC"). Therefore, the present invention does not impose any restrictions on the specific implementation method of the control module, and those skilled in the art can implement it in a reasonable manner as needed based on the teachings of the present invention, and these methods still fall within the scope of protection of the present invention.

[0023] Next, combine Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The above-mentioned movable guardrail mechanism 2 is exemplified. As an example, Figure 1 and Figure 2As shown, the movable guardrail mechanism 2 comprises a plurality of movable guardrail assemblies arranged in sequence along the conveying direction of the conveyor 200, each movable guardrail assembly comprises a first driver 21a fixedly arranged relative to the conveyor 200 and electrically connected to the control module, and a first guardrail body 22a arranged at the side of the conveyor 200 and capable of being driven by the first driver 21a to perform lifting and lowering motion. The first driver 21a may be a device capable of outputting linear motion, such as a pneumatic cylinder, an electric cylinder or a hydraulic cylinder. The first driver 21a can be fixedly arranged on the side or above the conveyor 200. When the first driver 21a is fixedly arranged on the side of the conveyor 200, if the first driver 21a drives the first guardrail body 22a to rise to the highest position, the movable guardrail mechanism 2 is in a blocking state, and the first guardrail body 22a can prevent the conveyed object 300 from falling from the side of the conveyor 200 away from the pushing mechanism 1. If the first driver 21a drives the first guardrail body 22a to drop to the lowest position, the movable guardrail mechanism 2 is in a released state, and the first guardrail body 22a allows the conveyed object 300 opposite thereto to be pushed away from the conveyor 200. When the first driver 21a is fixedly arranged above the conveyor 200, if the first driver 21a drives the first guardrail body 22a to rise to the highest position, the movable guardrail mechanism 2 is in a released state, and the first guardrail body 22a allows the conveyed object 300 opposite thereto to be pushed away from the conveyor 200. If the first driver 21a drives the first guardrail body 22a to descend to the lowest position, the movable guardrail mechanism 2 is in a blocking state, and the first guardrail body 22a can prevent the conveyed object 300 from falling from the side of the conveyor 200 away from the pushing mechanism 1. The specific structure of the first guardrail body 22a can be a fence structure, a plate structure or a structure similar to an angle steel.

[0024] As another example, Figure 4 and Figure 5 As shown, the aforementioned movable guardrail mechanism 2 includes a second driver 21b fixedly arranged relative to the conveyor 200 and connected to the control module, and a second guardrail body 22b rotatably arranged on the side of the conveyor 200 and driven to rotate by the second driver 21b. The second driver 21b can be selected as a linear drive device including a cylinder, an electric cylinder or a hydraulic cylinder, or can be selected as a rotation drive device that can directly output rotation and drive the second guardrail body 22b and its rotating shaft to rotate. It should be noted that when the second driver 21b is selected as a linear drive device, it needs to be connected to the rotating shaft of the second guardrail body 22b through a swing arm structure, so that the linear drive mechanism can drive the second guardrail body 22b to reciprocate within a certain range through the swing arm. When in use, when the second driver 21b drives the second guardrail body 22b to rotate so that it is higher than the conveying surface of the conveyor (see Figure 5), the movable guardrail mechanism 2 is in a blocking state, and the second guardrail body 22b can prevent the conveyed object 300 from falling from the side of the conveyor 200 away from the pushing mechanism 1, and when the second driver 21b drives the second guardrail body 22b to rotate so that it is lower than the conveying surface of the conveyor, the movable guardrail mechanism 2 is in a released state, and the second guardrail body 22b allows the conveyed object 300 opposite thereto to be pushed away from the conveyor 200. The specific structure of the first guardrail body 22a can be a fence structure, a plate structure, or a bent plate structure with a cross-section similar to a vertical fold stroke. It should be noted that when the width of the conveyor body 200a is smaller than the size of the material tray in this width direction, the first guardrail body 22a with a cross-section similar to a vertical fold stroke is more suitable for application on the conveyor body 200a so as to achieve a blocking function while taking into account a certain avoidance function.

[0025] In the two examples of the movable guardrail mechanism 2 mentioned above, Figure 2 or Figure 5 As shown, a plurality of first guardrail bodies 22a or a plurality of second guardrail bodies 22b can be configured to be arranged in the reverse direction of the conveying direction of the conveyor 200 and start from the position where the blocking mechanism 200b is located on the conveyor 200 (also the starting position where the conveyed objects 300 begin to gather on the conveyor 20), and in the conveying direction of the conveyor 200, the center distance between adjacent first guardrail bodies 22a or second guardrail bodies 22b is equal to the shortest center distance between adjacent trays on the conveyor 200. It should be noted that the shortest center distance between adjacent trays on the conveyor 200 should be understood as the center distance between adjacent trays on the conveyor 200 when they are in contact with each other. For example, when the cross section of the outer contour of the tray in the horizontal direction is a circle, the shortest center distance between adjacent trays on the conveyor 200 is equal to the sum of the radii of the two circles. For another example, when the cross section of the outer contour of the tray in the horizontal direction is a square, the shortest center distance between adjacent trays on the conveyor 200 is equal to the sum of the radii of the inscribed circles of the two squares. In this way, each material tray assembled in the temporary holding area and filled with raw food ingredients can be blocked or released by a corresponding first guardrail body 22a or second guardrail body 22b. When the selected conveyed object 300 is pushed away from the conveyor 200 by the pushing mechanism 1, the first guardrail body 22a or the second guardrail body 22b opposite to the selected conveyed object 300 needs to be lowered or rotated to a position that does not block the conveyed object 300 from leaving the conveyor 200. At the same time, the first guardrail body 22a or the second guardrail body 22b opposite to the unselected conveyed object 300 needs to move to or remain in a position that prevents the conveyed object 300 from leaving the conveyor 200. This can effectively prevent the unselected conveyed object 300 from leaving the conveyor 200 along with the selected conveyed object 300, thereby ensuring the normal progress of operations such as material transfer or material sorting.

[0026] like Figure 2 or Figure 5 As shown, the spacing between the first guardrail body 22a or the second guardrail body 22b and the pushing mechanism 1 in the vertical direction of the conveying direction of the conveyor 200 is approximately equal to the maximum size of the tray in this direction. In this way, the tray containing raw food can be conveyed more smoothly by the conveyor 200, and the tray containing raw food can be pushed away from the conveyor 200 more accurately by the pushing mechanism 1. More importantly, when the trays containing raw food are assembled and arranged in a linear array on the conveyor 200, the above definition helps each tray to be accurately aligned with each first guardrail body 22a or second guardrail body 22b one by one, thereby ensuring that the first guardrail body 22a or the second guardrail body 22b can better cooperate with the pushing mechanism 1, so that the pushing mechanism 1 can push the conveyed object 300 away from the conveyor 200 more accurately.

[0027] As another example, Figure 6As shown, the movable guardrail mechanism 2 includes a third driver 21c fixedly arranged relative to the conveyor 200, a third guardrail body 22c arranged on the third driver 21c and arranged along the conveying direction of the conveyor 200, a first linear slide 23c arranged on the side of the third guardrail body 22c away from the conveyor 200, and a fourth guardrail body 24c arranged on the first linear slide 23c and having a discharge opening. Among them, the third driver 21c can be selected to include a device that can output linear motion such as a cylinder, an electric cylinder or a hydraulic cylinder. The specific structure of the third guardrail body 22c can be a fence structure, a slat structure, etc., which is suitable for blocking materials. The first linear slide 23c can be selected as a screw-type electric linear slide mainly composed of a control motor (such as a servo motor or a stepping motor), a screw assembly and a slide rail assembly, or a belt-type electric linear slide mainly composed of a control motor, a synchronous belt assembly and a slide rail assembly. The fourth guardrail body 24c may optionally have a fence structure or a plate structure with a discharge opening, and the discharge opening should be selected to be a shape suitable for releasing the material tray. For example, when the material tray is selected to be a structure approximately cylindrical or cubic, the discharge opening may be selected to be rectangular. The control module is electrically connected to the third driver 21c and the first linear slide 23c. When the pushing mechanism 1 is about to push the selected object away from the conveyor 200, the control module can control the third driver 21c to drive the third guardrail body 22c to descend from a position that prevents the conveyed object 300 from leaving the conveyor 200 to a position that allows the conveyed object 300 to leave the conveyor 200, and then control the first linear slide 23c to drive the fourth guardrail body 24c to translate to a position where its discharge opening is aligned with the selected object. In this way, each material tray assembled in the temporary holding area and containing raw food ingredients can be selectively aligned and released by the discharge opening of the fourth guardrail body 24c. When the selected conveyed object 300 is pushed away from the conveyor 200 by the pushing mechanism 1, the part of the fourth guardrail body 24c except the discharge opening can effectively prevent the unselected conveyed object 300 from leaving the conveyor 200 along with the selected conveyed object 300 (i.e., the selected object), thereby ensuring the normal progress of operations such as material transfer or material sorting.

[0028] Next, combine Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The above-mentioned pushing mechanism 1 is described. As an example, Figure 1 and Figure 3As shown, the aforementioned pushing mechanism 1 includes a second linear slide 12a fixedly arranged relative to the conveyor 200 and electrically connected to the control module, and at least one pushing module 11a fixedly arranged on the second linear slide 12a. The second linear slide 12a can be optionally a screw-type electric linear slide mainly composed of a control motor (such as a servo motor or a stepper motor), a screw assembly and a slide rail assembly, or a belt-type electric linear slide mainly composed of a control motor, a synchronous belt assembly and a slide rail assembly. The second linear slide 12a is used to drive each pushing module 11a to perform linear reciprocating motion along the conveying direction of the conveyor 200, so that each pushing module 11a can selectively push the conveyed object 300 that enters the temporary retention area and stops at any position.

[0029] like Figure 1 and Figure 3 As shown, the picking and pushing device 100 may further include a fixed guardrail 3 disposed on one side of the temporary storage area of ​​the conveyor 200 and opposite to each movable guardrail mechanism 2. The fixed guardrail 3 is disposed to be lower than the lowest position of the pushing mechanism 1 and is located on the same side of the conveyor 200 together with the pushing mechanism 1. Therefore, the fixed guardrail 3 not only does not interfere with the pushing action of the pushing mechanism 1, but also can effectively prevent the conveyed object 300 from escaping from the side of the conveyor 200 close to the pushing mechanism 1.

[0030] As another example, Figure 4 As shown, the aforementioned pushing mechanism 1 includes a plurality of pushing modules 11b arranged along the conveying direction of the conveyor 200 and controlled by a control module, and each pushing module 11b can push the passing or opposite material tray and make it separate from the conveyor 200. Specifically, the plurality of pushing modules 11b are arranged in the opposite direction of the conveying direction of the conveyor 200 and start from the location of the blocking mechanism 200b of the conveyor 200. At the same time, in the conveying direction of the conveyor 200, the center distance between adjacent pushing modules 11b is equal to the shortest center distance between adjacent material trays on the conveyor 200. In this way, each material tray assembled in the temporary storage area and filled with raw food can be locked in a physical position by a corresponding pushing module 11b, ensuring that each pushing module 11b can push the passing or opposite material tray and make it separate from the conveyor 200.

[0031] In the two examples of the pushing mechanism 1 mentioned above, Figure 7 and Figure 8As shown, the pushing mechanism 1 includes a pushing module 11a or a pushing module 11b, and either of them includes a fourth driver 112 fixedly arranged on one side of the temporary storage area of ​​the conveyor 200 or arranged on the second linear slide 12a, and a pushing member 111 arranged on the fourth driver 112 and driven by the fourth driver 112 to move forward and backward. The fourth driver 112 can be selected to include a device that can output linear motion, such as a cylinder, an electric cylinder or a hydraulic cylinder. When the fourth driver 112 drives the pushing member 111 to move forward, the pushing member 111 can push the object 300 to be conveyed away from the conveyor 200, and when the fourth driver 112 drives the pushing member 111 to move backward, the pushing member 111 can return to the initial position before pushing the object 300 to prepare for the next object 300 to be conveyed.

[0032] like Figure 7 and Figure 8 As shown, the pushing member 111 at least includes a pushing portion 1111 for contacting and pushing the object 300. The surface of the pushing portion 1111 for contacting and pushing the object 300 can be a plane or an arc surface, wherein the arc surface can ensure that the pushing portion 1111 pushes the object 300 more smoothly.

[0033] As a preferred mode, the pushing member 111 may also include a first limiting tail 1112 connected to one side of the pushing portion 1111 and extending backward, and a second limiting tail 1113 connected to the other side of the pushing portion 1111 and extending backward, wherein the first limiting tail 1112 is away from the outer surface of the second limiting tail 1113 and the second limiting tail 1113 is away from the outer surface of the first limiting tail 1112 and parallel, and the distance between the two is substantially equal to the maximum size of the conveyed object 300 in the conveying direction of the conveyor 200. When the pushing member 111 pushes the conveyed object 300 directly opposite to it away from the conveyor 200, the first limiting tail 1112 and the second limiting tail 1113 can prevent the conveyed object 300 obliquely opposite to it from entering its own pushing range, thereby reducing the risk of adverse situations such as pushing the wrong object or pushing too much.

[0034] As a more preferred method, Figure 8As shown, the pushing member 111 may also include a first positioning angle portion 1114 connected to one side of the pushing portion 1111 and extending forward, and a second positioning angle portion 1115 connected to the other side of the pushing portion 1111 and also extending forward. Among them, the end of the first positioning angle portion 1114 away from the pushing portion 1111 and the end of the second limiting tail portion 1113 away from the pushing portion 1111 are parallel to each other, and the distance between the two is roughly equal to the size of the conveyed object 300 in the conveying direction of the conveyor 200. When the pushing member 111 is about to push the conveyed object 300 facing it, the first positioning angle portion 1114 and the second positioning angle portion 1115 not only improve the ability of the pushing member 111 to accurately push the conveyed object 300 facing it, but also ensure that the pushing mechanism 1 can accurately push the conveyed object 300 when the conveyor 200 is continuously running.

[0035] It should be noted that the fixed guardrail 3 mentioned above is not only suitable for Figure 1 In addition to the embodiment 1 shown, it is also applicable to Figure 4 In the second embodiment shown, the fixed guardrail 3 not only does not interfere with the pushing action of the pushing mechanism 1, but also can effectively prevent the conveyed object 300 from escaping from the side of the conveyor 200 close to the pushing mechanism 1. More preferably, when the pushing member 111 includes the first positioning angle 1114 and the second positioning angle 1115, the fixed guardrail 3 is arranged closer to the movable guardrail mechanism 2 than the pushing member 111, and the fixed guardrail 3 can prevent the conveyed object 300 from accidentally entering between the first positioning angle 1114 and the second positioning angle 1115 of the pushing member 111, which is conducive to ensuring that the conveyed objects 300 are neatly assembled in the temporary retention area of ​​the conveyor 200.

[0036] In summary, the picking and pushing device 100 mentioned in Embodiments 1 to 3 can not only smoothly push the conveyed object 300 out of the conveyor 200, but also effectively prevent the conveyed object 300 from accidentally leaving the conveyor 200 due to loss of control.
