Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of buffer machines, in particular to a buffer machine. BACKGROUND

[0002] A buffer machine is a device for temporarily storing and adjusting articles. In a production line, the production speeds of various processes may not be consistent. A buffer machine can temporarily store products of faster production processes and then send them out one by one when the subsequent slower processes have sufficient processing capacity, thereby ensuring the continuity and smoothness of the entire production process and avoiding production stagnation or product accumulation due to speed differences between processes. A buffer machine realizes the temporary storage and circulation of articles through its internal storage structure and conveying mechanism. Common conveying methods include synchronous belt conveying and chain transmission.

[0003] A buffer machine is disclosed in the utility model patent with publication number CN220810821U. When a workpiece is finished processing, it is sent into the buffer machine by the rollers after being sent into the slide rails on both sides of the fixed seat by the assembly line. This achieves the purpose of stably and quickly sending the processed workpieces on the assembly line into the buffer machine. However, this buffer machine takes a long time and requires more processes to take out the materials, resulting in low work efficiency. SUMMARY

[0004] The present application provides a buffer machine to solve the problem of low work efficiency due to multiple processes when accessing materials in existing buffer machines.

The second feeding mechanism is arranged in the buffering box, and the first feeding mechanism and the third feeding mechanism are respectively located on the two sides of the buffering box along the second direction. The conveying direction of the material holding plate is from the first feeding mechanism, the second feeding mechanism to the third feeding mechanism.

[0013] The driven magnetic wheels are arranged on the support, the plurality of driven magnetic wheels are sequentially distributed along the second direction, the axis of each driven magnetic wheel is arranged along the first direction, and the driven magnetic wheel can rotate around the axis thereof. The driving magnetic wheels and the driven magnetic wheels are magnetically attracted to each other, and each driving magnetic wheel corresponds to one driven magnetic wheel. The second feeding mechanism is located at the lower part of the first screw rod and the second screw rod.

[0014] Further, the cache machine further comprises a waste mechanism, the waste mechanism comprising a waste box, the waste box being arranged on the base in a sliding manner, and the waste box and the cache box being sequentially distributed along the first direction.

[0019] The beneficial effects of the present application are: the buffer machine of the present application, when the material needs to be stored, the first screw rotates forward, the second screw rotates reversely, the first spiral blade, the second spiral blade and the material plate contact, and drive the material plate to move upward. When the material in the buffer box needs to be taken out, the first screw reversely rotates, the second screw rotates forward, and drives the material plate to move downward. The material is stored and taken out through the rotation of the first screw and the second screw, which is convenient and fast, and the working efficiency is higher.

[0020] The pitch of the first spiral blade and the second spiral blade is greater than the thickness of the material plate, so that one material plate can be placed between the adjacent two turns of the first spiral blade. However, when facing different materials, the thickness of the materials is different. When the thickness of the material is less than the pitch of the first spiral blade, one material plate is stored between the adjacent two turns of the first spiral blade, that is, the adjacent material plates are spaced one turn apart. When the thickness of the material is greater than the pitch of the first spiral blade, the adjacent material plates are spaced two turns apart. When the thickness of the material is different, the pitch of the first spiral blade and the second spiral blade does not need to be changed, and the material of different thicknesses can be adapted, and the adaptability is stronger.

[0021] However, when the pitch of the first spiral blade and the second spiral blade is constant, the spacing between the materials is too large, which reduces the space utilization rate in the buffer box. Therefore, the first screw and the second screw are inclined, which increases the space utilization rate in the buffer box while ensuring that the adjacent two materials do not interfere with each other. The thicker the material, the smaller the distance between the first screw and the second screw and the vertical plane through the sliding motor box. During the process of gradually moving the material plate upward, due to the inclined arrangement of the first screw and the second screw, the contact position of the material plate and the first spiral blade and the second spiral blade changes, that is, the wear position on the material plate changes, thereby prolonging the service life of the material plate.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1 to 9 As shown in the figure, an embodiment of the present invention provides a buffer machine for temporarily storing materials. The materials are placed on a material holding plate 400 and include a base 100, a buffer box 200 and a buffer mechanism. The buffer box 200 is fixedly disposed on the base 100.

[0035] The buffer mechanism comprises two buffer assemblies distributed along a first direction, each buffer assembly comprising a first screw rod 300 and a second screw rod 340 distributed along a second direction, the first direction and the second direction are both horizontal directions, and the first direction is perpendicular to the second direction. The first screw rod 300 and the second screw rod 340 are both arranged obliquely, and the first screw rod 300 and the second screw rod 340 gradually move away along a direction from bottom to top. The first screw rod 300 is fixedly provided with a first spiral vane, and the second screw rod 340 is fixedly provided with a second spiral vane. The lower ends of the first screw rod 300 and the second screw rod 340 are both rotatably arranged on the buffer box 200, and the angle between the first screw rod 300, the second screw rod 340 and a vertical plane is adjustable.

[0036] The plurality of material holding plates 400 are distributed along a vertical direction, and the material holding plates 400 are placed on the first spiral vane and the second spiral vane. The first spiral vane and the second spiral vane are opposite in rotation direction, the pitch of the first spiral vane and the second spiral vane is the same, and is greater than the thickness of the material holding plate 400. The buffer mechanism has a first working state and a second working state, the first working state of the buffer mechanism is that the first screw rod 300 rotates forward and the second screw rod 340 rotates reversely to drive the material holding plate 400 to move upward. The second working state of the buffer mechanism is that the first screw rod 300 rotates reversely and the second screw rod 340 rotates forward to drive the material holding plate 400 to move downward. Wherein, the forward rotation and the reverse rotation are only to distinguish the rotation direction, and do not specify a particular rotation direction.

[0037] Since the first spiral vane and the second spiral vane are opposite in rotation direction, when the first screw rod 300 and the second screw rod 340 drive the material holding plate 400 to move upward or downward, the first screw rod 300 and the second screw rod 340 drive the material holding plate 400 to move in opposite directions along the second direction, so as to maintain the stability of the material holding plate 400.

[0038] When it is needed to store the material, the first screw rod 300 rotates forward, the second screw rod 340 rotates reversely, the first spiral vane, the second spiral vane and the material holding plate 400 are in contact, and the material holding plate 400 is driven to move upward. When it is needed to take out the material in the buffer box 200, the first screw rod 300 rotates reversely, the second screw rod 340 rotates forward, and the material holding plate 400 is driven to move downward. The material is stored and taken out through the rotation of the first screw rod 300 and the second screw rod 340, and the storage and taking out are both convenient and fast, and the working efficiency is higher.

[0039] The pitch of the first and second helical blades is greater than the thickness of the material containing plate 400, so that one pitch can accommodate one material containing plate 400. However, when facing different materials, the thickness of the materials is different. When the thickness of the material is less than the pitch of the first helical blade, one material containing plate 400 is stored in each pitch range, that is, the adjacent material containing plates 400 are spaced apart by one pitch. When the thickness of the material is greater than the pitch of the first helical blade, the adjacent material containing plates 400 are spaced apart by two pitches. When the thickness of the material is different, the pitch of the first and second helical blades does not need to be changed, and the material containing plate 400 can adapt to materials of different thicknesses, and the adaptability is stronger.

[0040] Since the pitch of the first and second helical blades is constant, if the spacing between the materials is too large, the space utilization in the cache box 200 will be reduced. Therefore, the first screw 300 and the second screw 340 are inclinedly arranged, which can increase the space utilization in the cache box 200 while ensuring that the adjacent two materials do not interfere with each other. Moreover, the thicker the material, the smaller the distance between the first screw 300 and the second screw 340 and the vertical plane through the sliding motor box 220. During the process of gradually moving the material containing plate 400 upward, since the first screw 300 and the second screw 340 are inclinedly arranged, the contact position between the material containing plate 400 and the first and second helical blades changes, that is, the wear position on the material containing plate 400 changes, thereby prolonging the service life of the material containing plate 400.

[0041] In the embodiment, each first screw 300 and each second screw 340 includes a static rod 310 and a dynamic rod 320. The lower end of the dynamic rod 320 is rotatably arranged on the cache box 200, and the upper end of the dynamic rod 320 is fixedly arranged with a connecting shaft 330, which is coaxially arranged with the dynamic rod 320. The static rod 310 is sleeved on the connecting shaft 330, and the connecting shaft 330 can rotate relative to the static rod 310.

[0042] The first and second helical blades each include a dynamic helical blade 321 and a static helical blade 311. The dynamic helical blade 321 is fixedly arranged on the dynamic rod 320, and the static helical blade 311 is fixedly arranged on the static rod 310. The dynamic helical blade 321 and the static helical blade 311 have the same rotation direction and pitch. In the initial state, the upper end of the dynamic helical blade 321 abuts against the lower end of the static helical blade 311.

[0043] When the number of material containing plates 400 on the static helical blade 311 exceeds the preset range value, the first motor 221 is turned off, the static rod 310 no longer rotates, and the material containing plate 400 on the static rod 310 no longer moves, so as to reduce the wear of the material containing plate 400. Then, the dynamic rod 320 rotates, the static rod 310 does not rotate, and the dynamic rod 320 continues to store the material containing plate 400.

[0044] In the embodiment, two chute assemblies are arranged in the buffer box 200, and the two chute assemblies are sequentially arranged along the first direction. Each chute assembly comprises two arc grooves 210, and the two arc grooves 210 are sequentially arranged along the second direction. The concave surface of the arc groove 210 faces downward. The upper end of each static rod 310 is provided with a motor box 220, and each motor box 220 is slidably arranged in an arc groove 210. The static rod 310 and the connecting shaft 330 are both rotatable relative to the motor box 220.

[0045] Each motor box 220 is slidably arranged in an arc groove 210, and the position of the motor box 220 in the arc groove 210 is adjustable. After the position of the motor box 220 is adjusted, the motor box 220 is fixed on the buffer box 200 by means of bolts. A first motor 221 and a second motor 222 are fixedly arranged in each motor box 220. The output shaft of the first motor 221 is fixedly connected with the static rod 310, and the output shaft of the second motor 222 is fixedly connected with the connecting shaft 330.

[0046] When it is necessary to adjust the angle between the first screw rod 300, the second screw rod 340 and the vertical plane, the bolts are removed, the motor box 220 is moved to a set position, and then the motor box 220 is fixed by means of bolts.

[0047] In the embodiment, two limiting plates 230 are fixedly arranged in the buffer box 200, and the two limiting plates 230 are sequentially arranged along the second direction. The limiting plate 230 is vertically arranged, and the first screw rod 300 and the second screw rod 340 are located between the two limiting plates 230. The limiting plate 230 is used to abut against the side surface of the material containing plate 400 along the second direction. The limiting plate 230 is used to limit the movement of the material containing plate 400 along the second direction.

[0048] In the embodiment, the buffer machine further comprises a first feeding mechanism 140, a second feeding mechanism 150 and a third feeding mechanism 160. The second feeding mechanism 150 is arranged in the buffer box 200, and the first feeding mechanism 140 and the third feeding mechanism 160 are respectively arranged on the two sides of the buffer box 200 along the second direction. The conveying direction of the material containing plate 400 is from the first feeding mechanism 140, the second feeding mechanism 150 to the third feeding mechanism 160.

[0049] The first feeding mechanism 140, the second feeding mechanism 150 and the third feeding mechanism 160 each comprise a support 540, a third motor 500, a rotating shaft 510, a plurality of driving magnetic wheels 520 and a plurality of driven magnetic wheels 530. The support 540 is arranged on the base 100, the third motor 500 is fixedly arranged on the support 540, the rotating shaft 510 is arranged along the second direction, and the output shaft of the third motor 500 is connected with the rotating shaft 510. The driving magnetic wheel 520 is fixedly arranged on the rotating shaft 510, and a plurality of driving magnetic wheels 520 are sequentially arranged along the second direction.

[0050] The driven magnetic wheels 530 are arranged on the support 540, and a plurality of the driven magnetic wheels 530 are sequentially arranged along the second direction, and the axis of each driven magnetic wheel 530 is arranged along the first direction, and the driven magnetic wheel 530 can rotate around its own axis. The driven magnetic wheels 530 and the driven magnetic wheels 530 are magnetically attracted, and each driven magnetic wheel 530 corresponds to one driven magnetic wheel 530. The second feeding mechanism 150 is arranged below the first screw rod 300 and the second screw rod 340.

[0051] In the embodiment, the waste mechanism further comprises a waste box 110, the waste box 110 is arranged on the base 100 in a sliding manner, and the waste box 110 and the buffer box 200 are sequentially arranged along the first direction. A plurality of clamping grooves are formed in the waste box 110, each clamping groove is arranged along the second direction, and the plurality of clamping grooves are arranged along the up-down direction. Each material plate 400 is placed in a clamping groove.

[0052] In the embodiment, the waste mechanism further comprises a hydraulic cylinder, the hydraulic cylinder is fixedly arranged on the base 100, and the hydraulic cylinder is fixedly connected with the waste box 110.

[0053] In the embodiment, the waste mechanism further comprises a reciprocating mechanism, the reciprocating mechanism comprises a conveying belt 120, a fourth motor and two transmission wheels, and the conveying belt 120 is arranged along the first direction. The transmission wheels are rotatably arranged on the base 100, and the two transmission wheels are respectively arranged on the two sides of the conveying belt 120 along the first direction, and the conveying belt 120 is rotatably arranged on the two transmission wheels. The fourth motor is fixedly arranged on the base 100, and the output shaft of the fourth motor is fixedly connected with one of the transmission wheels. The support 540 of the first feeding mechanism 140 is fixedly arranged on the conveying belt 120. The first feeding mechanism 140 has a first position and a second position, when the first feeding mechanism 140 is in the first position, the first feeding mechanism 140 can transport the material plate 400 to the second feeding mechanism 150, and when the first feeding mechanism 140 is in the second position, the first feeding mechanism 140 can transport the material plate 400 into the waste box 110. The conveying belt 120 is used to complete the conversion of the first feeding mechanism 140 between the first position and the second position.

[0054] The fourth motor drives the conveying belt to rotate in the forward direction, and the conveying belt transports the first feeding mechanism 140 to the waste box 110. Under the action of the first feeding mechanism 140, the material plate 400 is moved into the clamping groove. The hydraulic cylinder is started to drive the waste box 110 to continuously move upward to hold a plurality of material plates 400. Then the fourth motor is reversed to move the first feeding mechanism 140 to correspond to the second feeding mechanism 150 again.

[0055] In the embodiment, the buffer machine further comprises a sensing mechanism, the sensing mechanism comprising a sensor 130 and a controller, the sensor 130 being arranged on the base 100 and used for detecting whether the material on the first feeding mechanism 140 is qualified. The controller is arranged on the motor, and when the sensor 130 detects that the material is unqualified, the fourth motor is started through the controller, and the first feeding mechanism 140 is conveyed from the first position to the second position through the conveying belt 120.

[0056] In the embodiment, the buffer box 200 is provided with an observation window 201.

[0057] Working process: in the initial state, the first feeding mechanism 140 and the second feeding mechanism 150 correspond, and the upper end of the moving spiral blade 321 and the lower end of the static spiral blade 311 abut. The third motor 500 is started, the third motor 500 drives the rotating shaft 510 to rotate, and the driven magnetic wheel 530 is driven to rotate through the driving magnetic wheel 520. The material is placed on the material holding plate 400, and the material holding plate 400 is placed on the driven magnetic wheel 530 on the first feeding mechanism 140. The sensor 130 detects whether the material is qualified, and when the material is qualified, the material holding plate 400 is conveyed to the second feeding mechanism 150 under the driving of the driven magnetic wheel 530 on the first feeding mechanism 140.

[0058] When it is needed to store the material, the first motor 221 and the second motor 222 are started, so that the static rod 310 and the moving rod 320 rotate synchronously, the first screw rod 300 rotates in the positive direction, and the second screw rod 340 rotates in the reverse direction. After the moving spiral blade 321 contacts the material holding plate 400, the material holding plate 400 is driven to move upward. The material holding plate 400 moves from the moving spiral blade 321 to the static spiral blade 311.

[0059] Since the thickness of the material holding plate 400 is less than the pitch of the moving spiral blade 321, one material holding plate 400 can be placed between the adjacent two turns of the first spiral blade. However, when facing different materials, the thickness of the material is different. When the thickness of the material is less than the pitch of the moving spiral blade 321, one material holding plate 400 is placed between the adjacent two turns of the first spiral blade, that is, the adjacent material holding plates 400 are spaced by one turn. When the thickness of the material is greater than the pitch of the moving spiral blade 321, the adjacent material holding plates 400 are spaced by two turns. When the thickness of the material is different, the pitch of the first spiral blade and the second spiral blade does not need to be changed, and different thicknesses of the material can be adapted, and the adaptability is stronger.

[0060] And because the pitch of the spiral blade is certain, the spacing between the materials is too large to reduce the space utilization in the buffer box 200, so the first screw 300 and the second screw 340 are inclined to set, which increases the space utilization in the buffer box 200 while ensuring that the two adjacent materials do not interfere. And the thicker the material is, the smaller the spacing between the first screw 300, the second screw 340 and the vertical surface is through the sliding motor box 220. In the process of gradually moving the material plate 400 upward, because the first screw 300 and the second screw 340 are inclined to set, the contact position of the material plate 400 and the spiral blade changes, that is, the wear position on the material plate 400 changes, thereby prolonging the service life of the material plate 400.

[0061] When the number of the material plate 400 on the static spiral blade 311 exceeds the preset range value through observation of the observation chamber, the first motor 221 is turned off, the static rod 310 no longer rotates, and the material plate 400 on the static rod 310 no longer moves, so as to reduce the wear of the material plate 400.

[0062] When the material is unqualified, the fourth motor is started by the controller, the fourth motor drives the transmission belt to rotate forward, and the transmission belt transports the first feeding mechanism 140 to the waste box 110. Under the action of the first feeding mechanism 140, the material plate 400 is moved into the clamping groove. The hydraulic cylinder is started to drive the waste box 110 to move upward continuously to hold a plurality of material plates 400. Then the fourth motor reverses to move the first feeding mechanism 140 to correspond to the second feeding mechanism 150 again.

[0063] When the material in the buffer box 200 needs to be taken out, the first screw 300 reverses and the second screw 340 rotates forward, the first screw 300 and the second screw 340 drive the material plate 400 to move downward, and the material plate 400 is transported to the third feeding mechanism 160 under the action of the second feeding mechanism 150. The material is stored and taken out through the rotation of the first screw 300 and the second screw 340, which is convenient and efficient.
