Description

Technical Field

[0001] The utility model relates to the technical field of sports goods auxiliary equipment, in particular to a ball goods management device. Background Art

[0002] In school sports activities, balls are frequently used and varied, including basketball, football, volleyball, etc. Students actively participate in various ball games during recess or physical education classes, which provides a good platform for promoting physical health and teamwork. After the ball games, a collection cart similar to a supermarket shopping cart is usually used to collect and transport these ball supplies. The design of this collection cart is simple and convenient, and it can accommodate a variety of different types and sizes of balls, making it easy to move between the playing field and the storage area.

[0003] Although existing ball collection vehicles are relatively convenient to use, they have a significant problem: they cannot count the number of balls. Due to the lack of an effective counting mechanism, teachers and administrators cannot know the specific number of balls in a timely and accurate manner. This requires teachers or staff to manually count the number of ball supplies such as basketballs, footballs, volleyballs, etc. after each activity. This manual counting method is not only inefficient, but also prone to counting errors. Due to human factors such as distraction, fatigue or simple counting errors, it is easy to count wrong during the counting process, which leads to inaccurate records of the number of ball supplies. The loss of balls or mismatched quantities are therefore difficult to detect and correct in time. This inefficient and error-prone counting method is particularly inconvenient when managing large quantities of ball supplies, especially in schools and sports venues where ball supplies are frequently used.

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-6 The utility model provides a ball supplies management device, comprising a box body 1, a first blocking component 2, a second blocking component 3, a first photoelectric sensor 4, a second photoelectric sensor 5 and a display panel 9;

[0031] The upper part of the box body 1 is connected with a cover plate 11, and an addition port 12 is provided on the cover plate 11. The first photoelectric sensor 4 and the first blocking component 2 are respectively arranged on the lower surface of the cover plate 11. The first photoelectric sensor 4 is used to monitor the ball supplies falling from the addition port 12, and the first blocking component 2 is used to close the addition port 12.

[0032] The side wall of the box body 1 is provided with a discharge port 13, and the second blocking assembly 3 is provided on the inner wall of the box body 1 and is used to close the discharge port 13; a plate body 14 is further provided inside the box body 1, and the plate body 14 is obliquely provided inside the box body 1, and two guide plates 15 are provided on the upper surface of the plate body 14;

[0033] The display panel 9 is disposed on the upper surface of the cover plate 11 , the first photoelectric sensor 4 and the second photoelectric sensor 5 are both connected to the display panel 9 , and the display panel 9 is used to display the number of ball supplies inside the box 1 .

[0034] A controller (not shown in the figure) is provided in the display panel 9. After the first photoelectric sensor 4 and the second photoelectric sensor 5 detect the ball, an electrical signal is sent to the controller, and the controller controls the value on the display panel 9 to increase or decrease.

[0035] Furthermore, when in use, the first blocking component 2 is opened, and then the ball is placed through the addition port 12. During the falling process, the ball passes through the first photoelectric sensor 4. After the first photoelectric sensor 4 detects the ball, it sends an electrical signal to the controller. The controller controls the display panel 9 to increase the value by 1. Each time the first photoelectric sensor 4 detects a ball, the value of the display panel 9 increases by 1. When the balls are collected, the corresponding value on the display panel 9 is the number of balls in the box 1 at this time. When the ball needs to be taken out, the second blocking component 3 is controlled to be opened. After the second blocking component 3 is opened, the ball rolls down under the action of the inclined plate 14. At the same time, the two guide plates 15 guide the ball so that the balls in the box 1 are arranged in a straight line at the discharge port 13. Each time the second blocking component 3 is opened, a ball is discharged. When the ball is discharged from the discharge port 13, it passes through the second photoelectric sensor 5. After the second photoelectric sensor 5 detects the ball passing, it sends an electrical signal to the controller. The controller controls the display panel 9 to reduce the number of balls displayed by 1, so that the number of balls in the box 1 is controlled in real time. The display panel 9 monitors the number of balls in the box 1 in real time. After the balls are collected, the number of balls is directly known. After the balls are discharged, the discharge amount of balls can also be known according to the remaining number in the box 1. Thus, the management of balls is realized, and the problem that the existing ball collection device cannot count the number of balls is solved. The use of the ball supply management device also eliminates the need to count the number of ball supplies manually, effectively avoiding the problem of counting errors.

[0036] Among them, the first photoelectric sensor 5 and the second photoelectric sensor 6 can be but not limited to the existing reflective photoelectric sensors. The reflective sensor includes a transmitter (not shown in the figure) and a receiver (not shown in the figure), both of which are located in the same unit. When the ball enters their detection range, the light reflected by the object is captured by the receiver. When the ball passes through the first photoelectric sensor 4, the sensor detects the change in light and generates an electrical signal. The electrical signal is sent to the controller. After receiving the signal, the controller performs the corresponding operation according to the preset program-when the first photoelectric sensor 4 detects the ball, the value on the control display panel 9 increases by 1; similarly, when the second photoelectric sensor 5 detects the ball, the value on the control display panel 9 decreases by 1. The controller in this embodiment can be but not limited to the existing programmable logic controller (PLC), such as Siemens S7 series, Emerson ControlLogix or Schneider Modicon series. The specific working principle and use method of the controller are technical means well known to those skilled in the art, and will not be described in detail here.

[0037] Specifically, the side wall of the box 1 is provided with an observation glass 16. The setting of the observation glass 16 facilitates the observation of the state of the balls in the box 1. Furthermore, a color-changing light can be provided inside the box 1. When the number of balls in the box 1 is zero, the light is controlled by a controller to present a first color, and when balls are installed in the box, the light is controlled to present a second color. The first color is different from the second color.

[0038] Specifically, it also includes a vibration mechanism 6, which is arranged on the lower surface of the plate body 14; the vibration mechanism 6 includes a motor 61, an eccentric wheel 62 and a motor seat 63; the motor 61 is connected to the lower surface of the plate body 14 through the motor seat 63, and the eccentric wheel 62 is connected to the motor 61; the inner wall of the box body 1 is provided with two support plates 17, the two support plates 17 are at different heights, and two vertical plates 171 are respectively provided on the two support plates 17, and the plate body 14 is provided with a slide groove 141 matching the vertical plate 171, and the plate body 14 is arranged on the two support plates 17, and the vertical plate 171 is in the slide groove 141.

[0039] The setting of the vertical plate 171 and the slide groove 141 of the plate body 14 allows the plate body 14 to move in the box body 1. The two support plates 17 with different horizontal heights support the plate body 14 and also ensure that the plate body 14 is in an inclined state.

[0040] During use, due to the friction between the balls, there is friction between the balls and the plate body 14. Then the ball may get stuck at the entrance of the rolling channel formed by the two guide plates 15. When the "ball stuck" situation occurs, the motor 61 is started, and the output end of the motor 61 drives the eccentric wheel 62 to rotate. The eccentric wheel 62 is a wheel-shaped component, and its mass center is not at the geometric center, so centrifugal force is generated during rotation; due to the uneven mass distribution of the eccentric wheel 62, the rotation of the eccentric wheel 62 will generate periodic centrifugal force, and the motor 61 drives the plate body 14 to vibrate through the motor seat 63. The centrifugal force causes the motor 61 to vibrate. The motor 61 is firmly attached to the lower surface of the plate body 14 through the motor seat 63, so when the motor 61 vibrates, the vibration will be transmitted to the plate body 14. Since the plate body 14 is provided with a slide groove 141, which cooperates with the vertical plate 171, the plate body 14 can perform a small movement on the support plate 17. When the motor 61 vibrates, the plate body 14 will also vibrate. The stuck ball is displaced under the vibration of the plate 14 to solve the problem of the stuck ball, ensuring that the ball can roll normally. In addition, when the ball is released, the vibration mechanism 6 can be controlled to be in a working state, which can directly avoid the occurrence of the stuck ball situation.

[0041] Specifically, the first blocking assembly 2 includes a first steering gear 21 and a first blocking plate 22. The first steering gear 21 is installed on the lower surface of the cover plate 11. The first blocking plate 22 is connected to the output end of the first steering gear 21. The first steering gear 21 is used to drive the first blocking plate 22 to rotate; the first blocking plate 22 is used to close or open the addition port 12; the first steering gear 21 is started, and the output end of the first steering gear 21 drives the first blocking plate 22 to rotate. When the first blocking plate 22 is at the addition port 12, the addition port 12 is in a closed state. Due to the blocking effect of the first blocking plate 22, the ball cannot pass through the addition port. When the addition port 12 needs to be opened, the first steering gear 21 is controlled to drive the first blocking plate 22 so that the first blocking plate 22 cancels the blocking effect on the addition port 12, so that the ball can pass through the addition port 12 smoothly.

[0042] The second blocking assembly 3 includes a second servo 31 and a second blocking plate 32. The second servo 31 is installed on the inner wall of the box 1. The second blocking plate 32 is connected to the output end of the second servo 31. The second servo 31 is used to drive the second blocking plate 32 to rotate. The second blocking plate 32 is used to close or open the discharge port 13. When the second blocking plate 32 is at the discharge port 13, the ball is blocked by the second blocking plate 32 and cannot pass through the discharge port 13. When the ball needs to be discharged, the first servo 31 is controlled to drive the second blocking plate 32 to rotate. The movement of the second blocking plate 32 cancels the blocking of the discharge port 13, and the ball is discharged through the discharge port. Furthermore, after the second blocking plate 32 rotates a certain angle, the second servo 31 controls the second blocking plate 32 to return to its original position. That is, the second servo 31 drives the second blocking plate 32 to reciprocate.

[0043] The first steering gear 21 and the second steering gear 31 are existing servo motors. When the second blocking plate 32 is opened, the ball passes through the discharge port 13. After passing through the discharge port 13, the second photoelectric sensor 5 sends an electrical signal to the controller, and then the controller controls the second steering gear 31 to reversely drive the second blocking plate 32, so that the second blocking plate 32 is reset and continues to block the discharge port 13, that is, to ensure the smooth discharge of the ball, and quickly close the discharge port 13 after the discharge is completed.

[0044] Specifically, the lower surface of the cover plate 11 is provided with a first mounting seat 23 for mounting the first steering gear 21, and the first steering gear 21 is connected to the first mounting seat 23; the inner wall of the box body 1 is provided with a second mounting seat 33 for mounting the second steering gear 31, and the second steering gear 31 is connected to the second mounting seat 33. The first mounting seat 23 is used to carry the first steering gear 21, so that the first steering gear 21 is in a stable state. The second mounting seat 33 is used to carry the second steering gear 31, so that the second steering gear 31 is in a stable state.

[0045] Specifically, it also includes a third photoelectric sensor 7, which is arranged on the upper surface of the cover plate 11 and connected to the display panel 9. Specifically, the third photoelectric sensor 7 is used to monitor whether the ball is at the addition port 12. When the ball is at the addition port 12, the third photoelectric sensor 7 detects the ball, and then the third photoelectric sensor 7 produces an electrical signal and transmits the electrical signal to the controller. The controller controls the first steering gear 21 to start, and the first steering gear 21 drives the first blocking plate 22. The first blocking plate 22 cancels the blocking of the addition port 12. After the ball falls, the controller controls the first steering gear 21 to drive the first blocking plate 22 to rotate in the opposite direction to block the addition port 12 again.

[0046] More specifically, when the ball is located at the addition port 12, the third photoelectric sensor 7 detects the ball and generates an electrical signal, which is then transmitted to the controller. The controller receives the electrical signal from the third photoelectric sensor 7, and based on the received signal, the controller sends an instruction to the first servo 21, thereby driving the first blocking plate 22 to move to open the addition port 12. After the ball passes through, the controller sends a new instruction to the first servo 21, instructing it to rotate the first blocking plate 22 in the opposite direction to re-block the addition port 12. The controller has a delay mechanism, and a timing module is configured in the controller. Based on the estimated time required for the ball to pass through the addition port 12, the controller automatically sends an instruction to close the addition port 12 to the first servo 21 after a period of time after sending the instruction to open the addition port 12.

[0047] Specifically, a guide sleeve 18 is provided on the lower surface of the cover plate 11, and an extension portion 181 is provided on the guide sleeve 18. The extension portion 181 and the guide sleeve 18 are respectively provided with a plurality of connection portions 182. The guide sleeve 18 is connected to the lower surface of the cover plate 11 through the connection portions 182, and there is a gap between the guide sleeve 18 and the lower surface of the cover plate 11 for the first blocking plate 22 to move. A through hole is also provided on the guide sleeve 18 for the light beam of the first photoelectric sensor 4 to pass through, so as to ensure the actual use of the first photoelectric sensor 4. At the same time, the guide sleeve 18 also ensures that the ball falls vertically downward in the guide sleeve 18. When the ball interrupts the light beam, the sensor can detect and generate a corresponding signal, so as to ensure that the first photoelectric sensor 4 monitors the falling of the ball for accurate counting. Among them, a gap is designed between the guide sleeve 18 and the cover plate 11, and the gap allows the first blocking plate 22 to move smoothly therein.

[0048] Specifically, a conical guide portion 111 is provided on the upper surface of the cover plate 11. The setting of the conical guide portion 111 makes it easier for the ball to accurately enter the adding port 12.

[0049] Specifically, the box body 1 is also provided with a handle 19. The setting of the handle 19 is convenient for pushing or pulling the box body 1. In actual use, rollers can be selected to be provided at the bottom of the box body 1 to facilitate the transportation of the box body 1.

[0050] Specifically, the cover plate 11 is provided with a control button 8 for controlling the second blocking assembly 3. When the user presses this button, it sends an activation signal to the controller, and after receiving the signal from the control button 8, the controller interprets it as an instruction to start the second servo 31. Once the discharge port 13 is opened, the ball can be discharged smoothly through the discharge port 13. After the ball is discharged, the controller again sends an instruction to the second servo 31 to make it rotate in the opposite direction, so that the second blocking plate 32 returns to the initial position and closes the discharge port 13 again.

[0051] When the controller receives the instruction through the control button 8, the controller first activates the second servo 31 to rotate the second baffle 32, thereby opening the discharge port 13. In this process, the controller uses the built-in timing module to start the delay mechanism. The delay mechanism is based on the pre-set or calculated time required for the ball to pass through the discharge port 13 and roll out completely. For example, if it is estimated that it takes 1.5 seconds for a ball to be discharged, the controller will delay for 1.5 seconds after opening the second baffle 32, and then issue an instruction to let the second servo 31 drive the second baffle 32 to rotate in the opposite direction to close the discharge port 13. It is ensured that each ball has enough time to roll out of the discharge port 13, and the discharge port 13 can be closed in time.

[0052] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
