Description

Technical Field

[0001] The present application relates to the technical field of flow storage racks, and in particular to a buffer device and a flow rack for flow racks. Background Art

[0002] The flow rack conveys the goods from the distribution end to the pickup end through the roller track. The goods slide down automatically with the help of gravity, which can realize the "first in, first out" operation. It has the characteristics of low cost, fast storage speed and high density. Commonly used sliding containers include turnover boxes, parts boxes and cartons, which are suitable for large quantities of goods and short-term storage and picking.

[0003] For a long flow channel, in order to prevent the goods from sliding down too fast and causing collision damage, in addition to adjusting the installation angle of the flow strip, a buffer device needs to be installed on the flow channel. The general form of buffering is to install metal covers on certain rollers so that the goods cannot touch the rollers when sliding to that place, increasing the friction resistance. This type of cover-type buffer device has poor adaptability to the box type, weight, and outer packaging material of the goods. For example, light-weight goods packaged in paper packaging will stagnate in the flow channel due to excessive friction resistance, and cannot be started again after stagnation.

[0004] Therefore, in some cases, such as applications where goods are packaged in a variety of ways in the same flow channel, or applications where goods have different weights in the same flow channel, the existing buffer mechanism cannot meet the normal operation of the flow rack, and therefore a buffer device that can meet the above conditions is needed.

Implementation

[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0033] The implementation environment described in the embodiments of the present application is intended to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can appreciate that the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems in different implementation environments.

[0034] For the convenience of describing the technical solution, the present application defines that after the buffer device is assembled on the flow strip, the side of the operating panel body 11 close to the flow strip is defined as the inner side, and the side away from the flow strip is defined as the outer side; the side of the mounting plate body 31 close to the operating panel body 11 is the outer side, and the side of the mounting plate body 31 away from the operating panel body 11 is the inner side.

[0035] Let's first combine Figure 1-Figure 5 This application introduces the buffer device. Please refer to Figure 1, which shows a structural schematic diagram of an embodiment of the present application. Specifically, the buffer device of the present application includes: an operating plate portion 1, a fixed plate portion 2, a buffer portion 3 and an operating mechanism 4.

[0036] The operation panel part 1 includes an operation panel body 11 and a first channel 12 arranged on the operation panel body 11, wherein a first section channel 121 of the first channel 12 is close to the inner side of the operation panel body 11, a second section channel 122 of the first channel 12 is close to the outer side of the operation panel body 11, and one end of the second section channel 122 smoothly transitions to the inner side of the operation panel body 11 and is connected to the first section channel 121. Specifically, the operation panel body 11 can be made of sheet material or groove material, such as sheet steel, sheet aluminum, sheet alloy, etc., and the groove material can be selected from steel, aluminum or alloy C-shaped groove, angle groove, etc. The first channel 12 can be opened on the operation panel body 11 at the corresponding position of the fixed plate body 21 and / or the installation plate body 31, or the first channel 12 can be opened on the operation panel body 11 at a fixed interval. When the first channel 12 is opened on the operation panel body 11 at a fixed interval, part or all of the first channel 12 can be selected and used as needed. In addition, it should be noted that in order to clearly and briefly describe the technical solution, the present application divides the first channel 12 into two sections for description, that is, the first channel 12 is composed of the first section channel 121 and the second section channel 122. A possible structure thereof can be referred to Figure 4 As shown in the schematic diagram, the second section of the channel 122 smoothly transitions to the inner side of the operation panel body 11 along one end of the first section of the channel 121 and is connected to the first section of the channel 121. The angle between the second section of the channel 122 and the first section of the channel 121 at the smooth transition point is an obtuse angle, and the preferred angle is 120°-160°. It should be noted that the first channel 12 of the present application has the functions of the first section of the channel 121 and the second section of the channel 122 mentioned above. Of course, the functions of the two sections of the first channel 12 of the present application can also be set separately, that is, the first channel 12 is composed of two independent sections of the channel, and the two sections of the channel are not connected.

[0037] A structure of the fixing plate portion 2 can be referred to Figure 2As shown in the schematic diagram, the fixed plate portion 2 includes a fixed plate body 21, and a first moving device 22 disposed at one end of the fixed plate body 21, and the end of the fixed plate body 21 away from the first moving device 22 is used to be fixed to the bottom of the flow strip device. The fixed plate body 21 can be made of sheet material or groove material, such as sheet steel, sheet aluminum, sheet alloy, etc. The groove material can be selected from steel, aluminum or alloy C-shaped groove, angle groove, flat rectangular groove, flat tube, etc. The fixed plate body 21 is fixed to the bottom of the flow strip device by a fixed connection method, and the fixing method can be fixed by welding, bolts, screw connection, spline, wedge pin, etc.

[0038] A structural diagram of the buffer portion 3 can be referred to Figure 1 and Figure 3 As shown in the schematic diagram, the buffer part 3 includes a mounting plate body 31, a second moving mechanism 32 arranged at one end of the mounting plate body 31, and a buffer member 33 arranged on the mounting plate body 31. The mounting plate body 31 can be made of sheet material or groove material, such as sheet steel, sheet aluminum, sheet alloy, etc. The groove material can be selected from steel, aluminum or alloy C-shaped groove, angle groove, flat rectangular groove, flat tube, etc. In addition, the type of the buffer member 33 can be set to blocking type and friction type, and the number of the buffer members 33 can also be installed according to the type, length, use and other requirements of the fluent strip.

[0039] The operating mechanism 4 is used to drive the operating panel body 11, so that the first moving device 22 moves in the first section channel 121, and the second moving mechanism 32 moves in the second section channel 122. When the second moving device 32 moves to the end of the second section channel 122 away from the first section channel 121, the buffer member 33 generates resistance to the roller in the smooth strip device. Figure 1A structural schematic diagram is shown for explanation. In order to facilitate the explanation of the technical solution, the present application also defines the upper side of the accompanying drawings as the front, the lower side as the rear, the left side as the left, and the right side as the right. The second section channel 122 in the same first section channel 12 is located in front of the operating panel body 11, and the first section channel 122 is located behind the operating panel body 11. One end of the operating mechanism 4 is fixedly connected to one end of the operating panel body 11. When the operating mechanism 4 drives the operating panel body 11 to move forward, the second section channel 122 forces the second moving device 32 to move to the left, so that the buffer member 33 is away from the roller in the smooth strip device, reducing or losing the resistance to the roller in the smooth strip device. When the operating mechanism 4 drives the operating panel body 11 to move backward, the second section channel 122 forces the second moving device 32 to move to the right, so that the buffer member 33 is close to the roller in the smooth strip device, strengthening the resistance to the roller in the smooth strip device.

[0040] Combined with the above description, it can be known that when the flow rate of the goods on the flow strip is too fast or the resistance is too large, the buffer device of the present application can control the operating mechanism 4 to drive the operating plate body 11 to move forward and backward, so as to adjust the force of buffering and decelerating the goods, thereby controlling the flow rate of the goods on the flow strip. It is particularly suitable for applications with long flow channels, various packaging methods of goods in the same flow channel, and / or various weights of goods in the same flow channel.

[0041] In an improved implementation, the device type of the first moving device 22 matches the channel type of the first section of the channel 121, the device type of the second moving device 32 matches the channel type of the second section of the channel 122, the movement mode between the first moving device 22 and the first section of the channel 121 is sliding or rolling, and the movement mode between the second moving device 32 and the second section of the channel 122 is sliding or rolling. Specifically, the first channel 12 is set as a first wheel groove, the first moving device 22 is configured as a first groove wheel, and the second moving mechanism 32 is configured as a second groove wheel. Or the first channel 12 is set as an inverted T-shaped groove, a C-shaped groove or an I-shaped groove, the first moving device 22 is configured as a first pulley assembly, and the second moving mechanism 32 is configured as a second pulley assembly.

[0042] In another improved embodiment, the buffer member 33 includes a base 331 and a blocking device 332, wherein the blocking device 332 is disposed on the top of the base 331, and the blocking device 332 is configured as one of a shift fork, a pawl, and a friction plate. The base 331 and the blocking device 332 may be integrally formed, or may be connected together in a detachable manner, for example, the base 331 and the blocking device 332 are connected by means of threads, wedge keys, splines, pins, etc. Therefore, the type of the blocking device 332 can be replaced according to demand, and individual worn or damaged blocking devices 332 can also be replaced, which is convenient for use and maintenance.

[0043] In another improved embodiment, the blocking device 332 can be configured as a shift fork, and the fork arm of the shift fork is in the shape of a triangular pyramid, a cone, or a cylinder with an excessively pointed tip. Since a plurality of ribs are provided in the roller of the smooth strip, the front end of the fork arm is configured to be pointed, which facilitates the fork arm to extend between the ribs of the roller. In addition, the shift fork is provided with at least two fork arms arranged in sequence, and the preferred number of fork arms is set to 3-8. When more than three fork arms are provided, the preferred plurality of fork arms can be arranged at equal intervals, and at this time the distance between two adjacent fork arms is at least the distance between the center axes of two adjacent rollers.

[0044] The blocking device 332 can also be configured as a pawl, the pawl body of which is in the shape of a triangular pyramid, a cone, or a cylinder with an excessive tip, and preferably the pawl has at least two pawl bodies arranged in sequence. The principle of the blocking device 332 being configured as a pawl is the same as that of being configured as a fork, which will not be repeated.

[0045] When the blocking device 332 can also be set as a friction plate, the shape of the friction plate is annular, plate, cone or brake shoe. When the blocking device 332 is set as annular or plate friction plate, the ribs of the rollers in the smooth strip are axially or transversely arranged. When the operating mechanism 4 is used to drive the operating plate body 11, the friction end of the annular or plate friction plate can be close to the cylinder wall and / or ribs at the end of the roller, so that the speed of the roller at this place is slowed down or stopped. When the blocking device 332 is set as a conical friction plate, the ribs in the roller are set axially or transversely. There is a section of no ribs on the inner wall of the roller on the side of the blocking device 332. The operating mechanism 4 is used to drive the operating plate body 11 so that the conical friction plate can be close to the inner wall of the roller on the side of the blocking device 332.

[0046] In another improved embodiment, at least two long strip-shaped fixing slots 3311 are provided on the bottom plate of the base 331, and the position of the base 331 on the mounting plate body 31 is adjusted by adjusting the positions of the fixing slots 3311 and the fixing bolts. Preferably, three fixing slots 3311 are provided, which are arranged in a triangular shape in the middle of the base 331, and the length of the long strip-shaped fixing slots 3311 is greater than the diameter of the fixing bolts. The position of the buffer member relative to the roller can be adjusted according to the type or specification of the blocking device 332, so that the blocking device can better interact with the roller.

[0047] In another improved embodiment, when the smooth shelf is wider, more blocking devices 332 need to be used. In order to prevent the mounting plate body 31 from being too long, the end away from the operating plate body 11 moves downward under the action of gravity, which may cause the blocking device 332 to lose its function. Therefore, the mounting plate body 31 is also provided with a second channel 311 and a second moving device 312. A possible implementation method thereof can be referred to in the attached Figure 5 As shown in the schematic diagram, the second channel 311 is set as a second wheel groove, and the second moving device 312 is configured as a second groove wheel. When the second channel 311 is set as the second wheel groove, the second channel 311 is composed of a combination of a long strip slot and a circular slot, the margin between the two sides of the long strip slot is larger than the inner diameter of the second groove wheel, and smaller than the outer diameter of the second groove wheel, and the diameter of the circular slot is slightly larger than the outer diameter of the second groove wheel. When in use, the second groove wheel can be fixed to the bottom of the fluent strip by bolts, etc., and the groove body of the second groove wheel slides into the long strip slot through the circular slot, so that the mounting plate body 31 can be close to the fluent strip shelf, and the mounting plate body 31 can be moved relative to the fluent strip shelf, so that even if the mounting plate body 31 is long, the blocking device 332 installed on the mounting plate body 31 can also play a better role.

[0048] In another improved embodiment, the second channel 311 is provided with an inverted T-shaped groove, a C-shaped groove or an I-shaped groove, and the second moving device 312 is configured as a third pulley assembly. The pulley of the third pulley assembly moves in the groove of the second channel 311. When used in the same way, the second channel 311 and the third pulley assembly cooperate to bring the mounting plate body 31 close to the smooth shelf, and the mounting plate body 31 can move relative to the smooth shelf, so that even if the mounting plate body 31 is long, the blocking device 332 installed on the mounting plate body 31 can also play a better role.

[0049] In another improved implementation scheme, the operating mechanism 4 is configured as a hand lever, an electric telescopic rod or a hydraulic rod, and is fixed to one end of the operating panel body 11, and is used for the operating panel body 11 to move along its axial direction. For the sake of convenience, simple structure and low cost, the present application preferably configures the operating mechanism 4 as a hand lever. The specific structure of the hand lever can be referred to Figure 1 As shown in the schematic diagram, its structure specifically includes a rod body 41, a fixed connecting plate 42 and a handle 43. The fixed connecting plate 42 is in a Z shape and is used to fix one end of the rod body 41 to the end of the operating plate body 11. The handle 43 is arranged at the end of the rod body 41 on the side away from the operating plate body 11. When in use, the operator holds the handle 43, and then drives the rod body 41 to move forward or backward by pushing the handle 43, thereby controlling the operating plate body 11 to move forward or backward, so that the second section channel 122 forces the second moving device 32 to move leftward or rightward, so that the buffer member 33 is away from or close to the roller in the smooth strip device, and the state of the roller in the smooth strip device is controlled.

[0050] The second aspect of the present application provides a flow rack, comprising any of the buffer devices described above, and a flow strip 5, the structure of which can be referred to as Figures 6 to 9 As shown in the schematic diagram, the flow strip 5 includes a plurality of flow paths, each flow path includes an outer frame 51 and a roller 52, a fixing through hole 23 is provided on the side of the fixed plate body 21 away from the operating plate body 11, and is used to fix the fixed plate body 21 to the bottom of the outer frame 51, the operating plate body 11 is located at the bottom of the outer frame 51 and is arranged axially along the roller 52, the base 331 of the buffer member 33 is located in the gap between the flow paths, the blocking device 332 of the buffer member 33 is located at the upper part of the outer frame 51 and close to the roller 52, and the height of the blocking device 332 is lower than the highest position of the roller 52. Since the height of the blocking device 332 is higher than the highest position of the roller 52, the goods may be blocked.

[0051] In another improved implementation, the mounting plate body 31 is arranged perpendicular to the rotation direction of the roller 52, that is, the mounting direction of the mounting plate body 31 is perpendicular to the flow direction of the goods. There are two main considerations: When the blocking device 332 is configured as a fork or a pawl, the ribs of the roller 52 are axially arranged, and the operating mechanism 4 is used to drive the operating plate body 11 so that the end of the fork or the pawl can extend between the ribs of the roller 52. The end of the fork or the pawl is parallel to the axial direction of the roller 52, which not only has a good buffering effect, but also can prevent the end of the fork or the pawl from damaging the ribs or the wall of the roller 52. A possible structure in this case can be referred to Figure 7 and Figure 8 Schematic diagram shown.

[0052] When the blocking device 332 is configured as a friction plate, the operating mechanism 4 is used to drive the operating plate body 11 so that the friction plate can be closely attached to the inner wall of the roller 52 on one side of the blocking device 332. The mounting plate body 31 is arranged perpendicular to the rotation direction of the roller 52, and the friction force between the blocking device 332 and the roller 52 is large, so that the friction force on the blocking device 332 is uniform and the effect is the best.

[0053] In another improved embodiment, when the blocking device 332 is configured as a circular ring or plate friction plate, the ribs of the roller 52 are arranged axially or transversely, and the operating mechanism 4 is used to drive the operating plate body 11 so that the friction end of the friction plate can be in close contact with the cylinder wall and / or ribs at the end of the roller 52. It should be noted that each blocking device 332 is configured as a circular ring or plate friction plate, that is, one blocking device 332 has a buffering effect on one roller 52; of course, the blocking device 332 can also be a plurality of friction components arranged in sequence, so that one blocking device 332 can have a buffering effect on a plurality of rollers 52 at the same time; in addition, the blocking device 332 can also be a whole long plate friction plate, which can also have a buffering effect on a plurality of rollers 52 at the same time.

[0054] When the blocking device 332 is configured as a conical friction plate, the operating mechanism 4 is used to drive the operating plate body 11 so that the conical friction plate can be closely attached to the inner wall of the roller 52 located on one side of the blocking device 332. When the blocking device 332 is configured as a conical friction plate, the inner wall of the roller 52 located on one side of the blocking device 332 can also be configured with a certain taper, which matches the taper of the conical friction plate.

[0055] In another improved embodiment, the operating panel body 11 is provided with a plurality of first channels 12, the buffer portion 3 is provided with a plurality of mounting panel bodies 31, and each mounting panel body 31 is sequentially provided with a plurality of blocking devices 332. When the length of the flow strip is longer, the buffering distance required for the goods is longer. In this case, the buffer device needs more blocking devices 332, that is, more mounting panel bodies 31 need to be connected to the operating panel body 11, and each mounting panel body 31 is provided with a plurality of blocking devices 332. A possible structure can be specifically referred to in Fig. 9 Schematic diagram shown. In addition, according to the number of flow strips and actual conditions, the flow strip shelves can also be divided into flow channels, and the blocking devices 332 can also be modularly distributed and arranged according to the divided flow channels. For example, the flow strip shelves are divided into the first flow channel, the second flow channel, the third flow channel, etc., and the type of goods transported by each flow channel and the flow channel width may be different. Therefore, the type, quantity and arrangement of the blocking devices 332 can be set according to the flow channel conditions. For example, the blocking device 332 of the first flow channel is set to a fork or pawl type, and the blocking device 332 of the second flow channel is set to a friction plate type; for another example, the first flow channel has low requirements for deceleration, and the blocking devices 332 on the two adjacent mounting plate bodies 31 can be set at intervals; for another example, there is almost no cargo flowing between the two flow channels, and the blocking device 332 may not be set between the two flow channels.

[0056] In another improved embodiment, a groove is provided at the bottom of the outer frame 51, and the second moving device 312 is fixed by bolts. Preferably, the groove at the bottom of the outer frame 51 is continuous along the direction of the goods being transported in the smooth strip, that is, the groove is continuous from the front end of the bottom of the outer frame 51 to the rear end of the bottom of the outer frame 51. When in use, according to the number of second moving devices 312 to be fixed, the required fixing devices such as bolts are moved from the rear end or front end of the bottom of the outer frame 51 to a suitable position, and the second moving device 312 is fixed.

[0057] In summary, the buffer device of the present application can adjust the force of buffering and decelerating goods, and is particularly suitable for applications with long flow channels, various packaging methods of goods in the same flow channel, and / or various weights of goods in the same flow channel. In addition, the number and position of the first channel, the fixed plate body, the mounting plate body, and the blocking device can be set according to the length and width of the flow strip, and it can be applied to flow strips of various specifications, with strong applicability and practicality. Finally, the base of the present application and the blocking device can be set in a detachable manner for easy use and maintenance.
