Description

Technical Field

[0001] The utility model relates to a material loading and caching technology and the field of logistics transportation, and in particular to a box body caching material loading and conveying equipment. Background Art

[0002] Box conveying can be used in the transportation, distribution, storage, circulation processing and other links in factory logistics. It can centrally summarize parts to avoid missing or misplaced parts during the conveying process.

[0003] When the boxes are transported and loaded, because the speed of the conveyor line 10 does not match the entire production line, or there is a time delay between the conveyor line 10 and the next process, the boxes on the conveyor line 10 need to wait, resulting in excessive accumulation of boxes and lack of corresponding buffer;

[0004] Some existing structures are to provide baffles on the conveyor line 10, and release the boxes one by one for conveyance by opening and closing the baffles. However, because the conveyor line 10 is always in a working state, the rear box will continue to squeeze the front box, and under the impact of conveying, the baffle needs to withstand a large force, and when opened, it cannot guarantee the conveyance of a single box. Summary of the invention

[0005] The utility model aims to provide a box caching and feeding conveying device with a simple and compact structure. It can realize the sequential caching and feeding of multiple boxes without affecting the box conveying, so as to avoid squeezing caused by the accumulation of multiple boxes.

[0006] To achieve the above purpose, the box buffer feeding and conveying equipment includes:

[0007] The support frame has a conveying component at the bottom for receiving the box on the conveyor line, and the longitudinal width of the conveying component is smaller than the width of the box;

[0008] The buffer fixed plates are a pair and are longitudinally symmetrically located on both sides of the conveying component. Each buffer fixed plate is provided with a plurality of buffer support plates on the side facing the conveying component.

[0009] Multiple buffer support plates are arranged in intervals up and down, and the interval height is greater than the height of the box body. The buffer support plates adjacent to each other in the longitudinal direction are on the same horizontal plane and are used to receive the box body.

[0010] The driving component is located at the upper end of the supporting frame, and the output end is connected to a pair of buffer fixed plates to make them move up and down synchronously.

[0011] Furthermore, the driving component includes:

[0012] The driving motor is fixed on the supporting frame, and the dual output ends are respectively connected to the screw rod;

[0013] The spiral rods are a pair, each of which has a vertical axis and is threadedly connected to an ear seat on a corresponding buffer fixing plate.

[0014] Furthermore, the driving component also includes:

[0015] A guide rod, the axis of which is vertically mounted on the support frame;

[0016] The guide block is fixed on the buffer plate and slides relative to the guide rod.

[0017] Furthermore, a buffer rod is provided at the upper end of the support frame, facing downward and capable of acting on the upper end of the buffer fixed plate;

[0018] The buffer rod is provided with a sensor, and the controller controls the action of the driving component after receiving the sensing signal.

[0019] In the preferred solution, each buffer support plate is provided with a limit block for blocking the box conveying;

[0020] The limit block is a wedge-shaped structure, and the upper end is inclined at a higher position toward the conveying side of the box body.

[0021] Furthermore, the limit blocks are a pair and are arranged laterally at intervals, and the interval is greater than the width of the box;

[0022] The limit block is rotated through the support shaft and is located in the groove of the buffer support plate;

[0023] The support shaft is located at a biased position of the limiting block, so that the lowest position of the upper end of the limiting block rotates downward and is limited by the fixed block.

[0024] Compared with the prior art, the box buffer loading and conveying device drives the buffer fixed plate to move upward through the driving component, so that the multi-layer buffer support plate sequentially receives the box located on the conveying component, and the buffering of multiple boxes is realized without affecting the conveying of the box. The driving component drives the buffer fixed plate to move downward, so that the multi-layer buffer support plate sequentially lowers the received box to the conveying component, and the single sequential loading and conveying of the buffer box is realized, avoiding squeezing caused by the accumulation of multiple boxes.

[0025] Since a pair of limit blocks are provided on the buffer support plate, the box body that is transported back and forth horizontally can be limited, which is suitable for different usage environments; through the weight and rotation setting of the limit blocks, the box body can smoothly transition through the limit blocks on one side until it is limited by the limit blocks on the other side, avoiding a certain impact caused by the box body falling.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The description is given by assuming that the box is transported horizontally on the conveyor line 10;

[0040] like Figures 1 to 4 As shown, the box-type buffer feeding and conveying equipment includes:

[0041] The support frame 20 has a conveying member 60 at the bottom for receiving the box on the conveyor line 10, and the longitudinal width of the conveying member 60 is smaller than the width of the box;

[0042] The buffer fixed plates 35 are a pair and are longitudinally symmetrically located on both sides of the conveying component 60. A plurality of buffer support plates 36 are provided on a side of each buffer fixed plate 35 facing the conveying component 60.

[0043] A plurality of buffer support plates 36 are arranged at intervals up and down, and the interval height is greater than the height of the box body, and the buffer support plates 36 adjacent in the longitudinal direction are on the same horizontal plane and are used to receive the box body;

[0044] The driving component is located at the upper end of the support frame 20, and the output end is connected to a pair of buffer fixed plates 35 and makes them move up and down synchronously;

[0045] Specifically, the support frame 20 is an integral support structure, and a rectangular tube can be used to form a frame by welding; the conveying component 60 is a plurality of rollers rotating in the same direction, and the width of the rollers is smaller than the width of the conveying box, so that the buffer support plate 36 can support the box. This is a traditional conveying structure and will not be further described here;

[0046] The buffer fixed plate 35 is a vertical plate structure, which is longitudinally symmetrically arranged on both sides of the conveying component 60; each buffer fixed plate 35 is provided with a plurality of buffer support plates 36, and the distance between the upper and lower buffer support plates 36 can ensure the entry of the box, that is, after the box enters the conveying component 60, the buffer support plates 36 can receive the box;

[0047] A driving component, used for driving the buffer fixing plate 35 to move up and down;

[0048] When the box buffer loading and conveying device is in use, multiple boxes are conveyed and loaded on the conveying line 10;

[0049] In the initial state, the driving component drives the buffer fixed plate 35 to move downward, so that the uppermost buffer support plate 36 is horizontal or slightly lower than the upper end section of the conveying component 60;

[0050] The buffer support plates 36 are defined as A, B, C, ... from top to bottom, and the corresponding boxes are defined as A, B, C, ... for illustration;

[0051] When multiple boxes are transported and piled up and need to be cached, box A moves to the cache fixed plate 35 on the conveying component 60, the driving component drives the cache fixed plate 35 to move upward, the uppermost cache support plate 36A receives box A, and the lower cache support plate 36B moves to the position of the cache support plate 36A at the initial position, waiting for box B; when box B moves to the cache fixed plate 35 on the conveying component 60, the driving component drives the cache fixed plate 35 to move upward at equal intervals, the cache support plate 36B receives box B, and the lower cache support plate 36C moves to the position of the cache support plate 36A at the initial position, waiting for box C;

[0052] The multiple layers of buffer support plates 36 are directly connected to the box body to complete the maximum buffering of the device. That is, the buffer fixed plate 35 is located at the top, and the bottom buffer support plate 36 is higher than the conveying component 60.

[0053] When the cache box is loaded, the driving component drives the cache fixed plate 35 to move downward, so that the box located on the cache support plate 36 is re-taken by the conveying component 60 to complete the corresponding conveying; it is explained that when the driving component drives the cache fixed plate 35 to move up and down, it is raised and lowered at equal intervals based on the initial position to complete the positioning of the multi-layer cache support plates 36.

[0054] The box caching and loading conveying equipment drives the cache fixing plate 35 to move upward through the driving component, so that the multi-layer cache support plate 36 successively receives the boxes located on the conveying component 60, and realizes the caching of multiple boxes without affecting the conveying of the boxes. The driving component drives the cache fixing plate 35 to move downward, so that the multi-layer cache support plate 36 successively lowers the received boxes to the conveying component 60, and realizes the loading and conveying of the cache boxes.

[0055] like Figure 3 , Figure 4 As shown, in the preferred embodiment, the driving component includes:

[0056] The driving motor 31 is fixed on the supporting frame 20, and the dual output ends are connected to the screw rod 33 respectively;

[0057] The spiral rods 33 are a pair, each spiral rod 33 has a vertical axis and is threadedly connected to an ear seat 34 on a corresponding buffer fixing plate 35;

[0058] Furthermore, the driving component also includes:

[0059] A guide rod 37, the axis of which is vertically mounted on the support frame 20;

[0060] A guide block 38 is fixed on the buffer plate 35 and slides relative to the guide rod 37;

[0061] Specifically, a support plate 21 may be provided at the upper end of the support frame 20 for supporting the driving component;

[0062] The driving motor 31 can be a servo motor and connected to the controller. The output end of the driving motor 31 can be connected to the reducer 32. The reducer 32 is a dual-output structure and is correspondingly connected to the screw rod 33. The upper and lower parts of the screw rod 33 can be rotatably mounted on the fixed seat through bearings.

[0063] After the driving motor 31 is started, it drives the screw rod 33 to rotate, so that a pair of buffer fixing plates 35 threadedly connected to the screw rod 33 move up and down synchronously;

[0064] The guide rod 37 is used for guiding, and the guide block 38 is equivalent to a slider, that is, the guide block 38 is installed on the cache fixing plate 35 and can be connected to the guide rod 37 through a linear bearing; the guide block 38 cooperates with the guide rod 37 to ensure the stability of the up and down movement of the cache fixing plate 35.

[0065] like Figures 1 to 4 As shown, in the preferred embodiment, a buffer rod 40 is provided at the upper end of the support frame 20 and is downwardly directed and can act on the upper end of the buffer fixing plate 35;

[0066] The buffer rod 40 is provided with a sensor, and the controller controls the action of the driving component after receiving the sensing signal;

[0067] Specifically, the buffer rod 40 is used to buffer and limit the upward movement of the cache fixing plate 35; that is, when the cache fixing plate 35 moves upward to the highest position, the buffer rod 40 can elastically contact the cache fixing plate 35, and the sensor on the buffer rod 40 can be a pressure sensor. When the pressure sensing reaches a set range, it indicates that the cache fixing plate 35 has reached the highest position, and the controller controls the driving component (driving motor 31) to stop working.

[0068] like Figure 5 As shown, in the preferred embodiment, each buffer support plate 36 is provided with a limit block 51 for blocking the box conveying;

[0069] The limit block 51 is a wedge-shaped structure, with the upper end inclined at a higher position toward the conveying side of the box body;

[0070] Specifically, the limit block 51 is used to limit the box body, that is, when the box body is transported horizontally on the conveying member 60 and the buffer support plate 36 moves upward to receive the box body, the box body may not be fixed on the buffer support plate 36 due to the inertia of the box body, and may even slide off the buffer support plate 36;

[0071] The wedge-shaped limit block 51 can limit the box in the conveying state;

[0072] As explained, in the initial stage, the limit block 51 on the buffer support plate 36 for receiving the box body must meet the following requirements: the highest point of the upper end surface of the limit block 51 is higher than the upper end section of the conveying component 60 .

[0073] like Figure 5 , Figure 6 As shown, further, the limit blocks 51 are a pair and are arranged laterally at intervals, and the interval is greater than the width of the box;

[0074] The limit block 51 is rotated through the support shaft 53 and is located in the groove of the buffer support plate 36;

[0075] The support shaft 53 is located at a biased position of the limiting block 51 , so that the limiting block 51 is rotated downward at the lowest position of the upper end and is limited by the fixing block 52 .

[0076] Specifically, a pair of limit blocks 51 are arranged at intervals in the transverse direction, and the distance between them is greater than the width of the box body. The purpose is to be applicable to the transverse reciprocating limit of the box body, that is, it can be used to limit the box body when it is conveyed from left to right, or when it is conveyed from right to left. After the limit, the box body is located between the pair of limit blocks 51, which is applicable to different feeding and conveying environments of the box body.

[0077] In the initial state, when the limiting block 51 is arranged eccentrically, the lowest position of the upper end of the limiting block 51 rotates downward and is limited by the fixing block 52, that is, the high positions of a pair of limiting blocks 51 are arranged facing each other;

[0078] When the limit block 51 is fixedly arranged, the following problems exist: 1. When the box is transported by the conveying member 60 and passes through the upper inclined surface of the limit block 51, one end of the box will be lifted and then fall, which will cause a certain impact on the box, especially when fragile items are placed in the box, which is prone to damage; 2. For example, when the box is transported horizontally from left to right, when the inclination angle of the upper end surface of the limit block 51 is too large, although the right limit block 51 has a better limiting effect on the box, there is a problem that the box cannot pass through the left limit block 51 smoothly;

[0079] This solution uses the biased and rotating setting of the limit block 51 to allow the box to smoothly transition through the limit block 51 on one side until it is limited by the limit block 51 on the other side. For example, when the box is transported horizontally from left to right, it first passes through the limit block 51 on the left side, that is, the box moves along the upper end surface of the limit block 51, and as the moving position changes, it will drive the limit block 51 to rotate on the support shaft 53, so that the box passes through the limit block 51 smoothly, continues to be transported and is limited by the limit block 51 on the right side, and at the same time, the limit block 51 on the left side is restored to its initial state when it is biased; similarly, when the box is transported horizontally from right to left, the box first passes through the limit block 51 on the right side for a smooth transition, continues to be transported and is limited by the limit block 51 on the left side, and the limit block 51 on the right side is restored to its initial position.

[0080] Example

[0081] In the initial state, the uppermost buffer support plate 36 is horizontal or slightly lower than the upper end section of the conveying member 60, and the upper end surface of the uppermost stopper 51 is lower than the conveying member 60. At this time, the box body normally transitions from the conveying line 10 to the conveying member 60 and then performs the loading process;

[0082] When the boxes are piled up and need to be cached during transportation, the driving component drives the cache fixed plate 35 to move upward, so that the upper end surface of the uppermost limit block 51 is higher than the upper end section of the conveying component 60. At this time, the box transitions from the conveying line 10 to the conveying component 60, and then passes through the limit block 51 on one side that is biased and rotated, and smoothly transitions, and then resists the limit through the limit block 51 on the other side. Finally, the box is located between a pair of limit blocks 51, and the driving component drives the cache fixed plate 35 to move upward, so that the uppermost cache support plate 36 receives the box and separates from the conveying component 60, and the second-layer cache support plate 36 is located at the position of the uppermost cache support plate 36 in the initial state;

[0083] When multiple boxes are stacked and need to be cached, the above steps are performed in sequence, so that the multi-layer cache support plate 36 sequentially receives the boxes until the maximum cache capacity is reached;

[0084] When the buffer box is loaded, the driving component drives the buffer fixed plate 35 to move downward, so that the box on the buffer support plate 36 is received by the conveying component 60 again, and the upper end surface of the limit block 51 is lower than the upper end section of the conveying component 60, and the box is completely out of the limit of the limit block 51, completing the corresponding conveying;

[0085] As explained, a sensor for monitoring the position of the buffer support plate 36 or the limit block 51 may be provided on the support frame 20. The sensor may be a photoelectric sensor, a laser sensor, etc. The sensor is connected to the controller to control the action of the driving component, which includes starting, stopping, and forward and reverse rotation, thereby realizing automatic buffering and conveying of the box buffer feeding and conveying device;

[0086] In addition, since a pair of limit blocks 51 are provided on the buffer support plate 36, when the box is transported back and forth, the box buffer loading and conveying equipment can realize the buffer transportation of the box back and forth.
