Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an automatic corner protection device for a baler and a baler. Background Art

[0002] During the packaging process, the outer corners of the materials are easily damaged or damaged. When bundling materials, the strapping tape rubs against the corners of the materials due to its tightness, which may damage the outer packaging. Usually, in order to protect these corners, corner guards are placed at the corresponding positions of the materials before bundling.

[0003] With the development of automation technology, a variety of automation equipment has appeared in the market in recent years to realize the automatic loading and bundling of short corner guards. These existing balers' automatic corner guard devices usually include a loading assembly and a feeding assembly. The loading assembly consists of a silo assembly and a pushing assembly. The silo assembly is arranged vertically. The silo assembly is used to store the stacked short corner guards, while the pushing assembly is located below the silo assembly and is responsible for receiving the short corner guards at the bottom layer each time and moving them to the loading position. The feeding assembly is located between the loading assembly and the lifting member. Its function is to pick up the short corner guards at the loading position and place them at the corners of the material.

[0004] However, this automatic corner guard device has some design deficiencies. Since the silo is arranged vertically, the placement direction of the short corner guard does not match the actual position of the material corner, resulting in the feed assembly requiring an additional flipping mechanism to adjust the corner guard to a horizontal state. This not only increases the structural complexity of the feed assembly, but also, since the feed assembly only releases the short corner guard at the material corner, the corner guard may not be effectively attached to items with irregular shapes or non-standard angles, thus affecting the overall packaging effect. Utility Model Content

[0005] Based on this, it is necessary to provide a baler automatic corner protection device and a baler to address the problems that the automatic corner protection device has a complex structure and poor adaptability to irregular objects.

The corner guard moving assembly also includes a lifting assembly, which is used to drive the first adsorption assembly to move up and down.

[0010] The above-mentioned automatic corner guard device for the baler can store short corner guards in a manner that is closer to the corners of the materials due to the inclined storage chamber. This can reduce the need for rotation due to mismatch in the direction of the short corner guards and simplify the structure. Moreover, the corner guard moving assembly also includes a lifting assembly. When the corner guard is moved to the corner of the article to be packaged, the lifting assembly drives the corner guard to move downward so that it is in close contact with the corner of the material, making it easier to fit materials of various shapes and improving the packaging effect.

[0016] In one embodiment, the first sensor and the second sensor are contact sensors, and the first counterweight and the second counterweight are provided with a trigger part. When the first counterweight or the second counterweight moves to the bottom of the first storage chamber or the second storage chamber, the first counterweight or the second counterweight triggers the first sensor and the second sensor.

[0017] In one of the embodiments, a first stroke sensor and a second stroke sensor are further included, wherein the first stroke sensor and the second stroke sensor are spaced apart in front and back along the first direction, and are used to control the stroke of the pusher.

[0045] See also Figure 1 An embodiment of the utility model provides an automatic corner protection device for a baler, comprising a corner protection loading component 10 and a corner protection moving component 20.

[0046] Corner guard loading components

[0047] The corner guard feeding assembly 10 is used to feed the corner guard 30 ( Figure 5 ) to the loading position. Also refer to Figure 1-2 The corner guard loading assembly 10 includes a silo assembly 11 and a push assembly 12. The silo assembly 11 has a first direction ( Figure 1 The first storage chamber 111 and the second storage chamber 112 are arranged side by side in the first direction and the second direction ( Figure 1 The plane defined by the "Y" direction in the middle is inclined at a certain angle to facilitate the sliding and storage of the corner protector 30. A discharge port is provided at the lower end of each storage chamber for the smooth release of the corner protector 30.

[0048] In one embodiment, the silo assembly 11 further includes a first counterweight 113 and a second counterweight 114, which are respectively located in the first storage chamber 111 and the second storage chamber 112 and can be freely raised and lowered. The main function of the first counterweight 113 and the second counterweight 114 is to apply uniform and appropriate downward pressure on the stacked corner guards 30. The application of such pressure ensures that the corner guards 30 can stably and continuously slide to the load-bearing portion below, thereby avoiding jamming or blockage that may occur during the transportation of the corner guards 30. In this embodiment, the cross-section of the first counterweight 113 and the second counterweight 114 is a "∟" type ( Figure 5 ).

[0049] In one embodiment, the silo assembly 11 further includes a first sensor 115 and a second sensor 116, which are respectively arranged on one side of the first storage chamber 111 and the second storage chamber 112. The main function of the first sensor 115 and the second sensor 116 is to detect the stock of the corner guard 30 in the respective storage chambers in real time, especially to identify whether the storage chambers are empty. This function is crucial to ensure the continuous operation of the automatic corner guard device. The sensor can send storage chamber status information to the control system in a timely manner, such as the presence or absence of the corner guard 30 in the storage chamber, so that the control system can make corresponding adjustments or instruct the operator to refill before the storage chamber is empty, so as to avoid the baler shutdown caused by the empty storage chamber. As an example, the first sensor 115 and the second sensor 116 are both contact sensors, and the first counterweight 113 and the second counterweight 114 are respectively provided with a first trigger part 113a and a second trigger part 114a. When the first counterweight 113 and the second counterweight 114 move to the bottom of the storage chamber, the first trigger part 113a or the second trigger part 114a triggers the first sensor 115 or the second sensor 116.

[0050] The pusher assembly 12 is a key part of the automatic corner protection device, which is responsible for accurately taking out the corner protector 30 from the silo assembly 11 and conveying it to the loading position. The assembly is located directly below the silo assembly 11 and includes a pusher 121 and a pusher drive assembly 122.

[0051] Also refer to Figure 3 and Figure 5 , the pushing piece 121 can effectively reciprocate between the material receiving position and the material loading position along the first direction. The pushing piece 121 is a strip extending along the first direction, and the pushing piece 121 has a first bearing portion 1211 and a second bearing portion 1212 arranged front and back on its length. The surface of the first bearing portion 1211 is designed to be slightly recessed downward relative to the surface of the second bearing portion 1212, forming a unique pushing step structure. This design enables the first bearing portion 1211 to accurately align with the discharge port of the first storage chamber 111 or the second storage chamber 112 when in the material receiving position, thereby effectively receiving and carrying the corner protector 30 located at the bottom layer of the storage chamber. When the pushing piece 121 moves to the material loading position, the first bearing portion 1211 will extend, making it easier for the corner protector 30 to be grasped by the corner protector moving assembly 20.

[0052] The driving end of the push drive assembly 122 is connected to the push piece 121, and is used to drive the push piece 121 to reciprocate between the material receiving position and the material loading position. As an example, the push drive assembly 122 is an electric cylinder, which includes a servo motor 122a and a slider 122b, and the slider 122b is connected to the push piece 121.

[0053] When the first material storage chamber 111 is in a non-empty state, that is, there are still corner protectors 30 inside, the push drive assembly 122 is activated to drive the first bearing portion 1211 to move to just below the discharge port of the first material storage chamber 111. At this position, the bottom corner protectors 30 in the first material storage chamber 111 naturally fall onto the surface 1211a of the first bearing portion due to gravity. Subsequently, the push drive assembly 122 moves the first bearing portion 1211 and the corner protectors 30 it carries to the loading position for further handling and processing. At the same time, the penultimate corner protectors 30 in the first material storage chamber 111 and the bottom corner protectors 30 in the second material storage chamber 112 fall onto the surface 1212a of the second bearing portion, preparing for the next round of operation.

[0054] When the first storage chamber 111 is empty, that is, no corner protector 30 is stored, the push drive assembly 122 moves the first bearing portion 1211 to just below the discharge port of the second storage chamber 112. At this new position, the bottom layer of corner protectors 30 in the second storage chamber 112 falls onto the surface 1211a of the first bearing portion, and is then sent to the loading position. In this process, the penultimate layer of corner protectors 30 in the second storage chamber 112 falls onto the surface 1212a of the second bearing portion, waiting for the next operation.

[0055] It should be particularly pointed out that the cross section of the corner protector 30 is designed to be "∟" shaped. This unique shape requires the surface of the bearing part of the pusher 121 to match the inner surface of the corner protector 30. Therefore, in this embodiment, the bearing part of the pusher 121, that is, the surface of the first bearing part 1211 and the second bearing part 1212, are designed to be a "∟" shaped structure that matches the cross section of the corner protector. This design ensures the stability of the corner protector 30 during movement and the adaptability to the shape of the corner protector 30, thereby effectively reducing the sliding or flipping of the corner protector 30 during movement.

[0056] In one embodiment, a suction port 1211b is provided on the first carrying portion 1211, and a second suction cup assembly 123 is installed in the suction port 1211b. When the corner protector 30 smoothly falls onto the surface of the first carrying portion 1211, the second suction cup assembly 123 in the suction port 1211b is activated, generating sufficient suction force to firmly attach the corner protector 30 to the carrying portion. This mechanism ensures the stability of the corner protector 30 during the entire handling process, especially when accelerating and changing direction, and effectively prevents the corner protector 30 from sliding or falling.

[0057] In one embodiment, a plurality of strip-shaped holes 1212b extending along the first direction are provided on the second bearing portion 1212. The main purpose of these strip-shaped holes 1212b is to reduce the contact area between the surface of the second bearing portion 1212 and the corner protector 30. By reducing the contact area, the friction resistance between the second bearing portion 1212 and the corner protector 30 when the second bearing portion 1212 is extended can be significantly reduced. This design allows the corner protector 30 to slide off or be moved from the second bearing portion 1212 more easily, thereby improving the fluency and efficiency of the entire handling process.

[0058] In one embodiment, a first stroke sensor 124 and a second stroke sensor 125 are further included. The first stroke sensor 124 and the second stroke sensor 125 are spaced apart in front and back along the first direction to control the stroke of the pusher.

[0059] In one embodiment, the corner guard loading assembly 10 further includes a bracket assembly 13, on which the corner guard loading assembly 10 and the corner guard moving assembly 20 are both mounted. The bracket assembly 13, as the skeleton of the entire device, not only provides a solid support for the corner guard loading assembly 10, but also provides necessary fixation and guidance for the operation of the corner guard moving assembly 20. The bracket assembly 13 is composed of a bottom plate 131, a vertical plate 132 and two side plates 133, which together form a solid support frame. The bottom plate 131 extends along a first direction, providing a basic platform for the device. The vertical plate 132 also extends along the first direction, and its lower end is tightly connected to one end of the bottom plate 131 along the second direction, forming the main vertical support of the device. The two side plates 133 are arranged opposite to each other along the first direction, and are fixedly connected to the bottom plate 131 and the vertical plate 132, and the lower end of the silo assembly 11 is fixedly connected to the two side plates 133 respectively. The two side plates 133 enhance the structural stability of the entire bracket. This design ensures that the corner guard loading assembly 10 and the corner guard moving assembly 20 can remain stable during operation, reducing displacement or error caused by mechanical vibration or load change. The lower end of the silo assembly 11 is fixedly connected to the two side plates 133, ensuring the accuracy and stability of the silo assembly 11 when carrying the corner guard 30.

[0060] In this embodiment, the silo assembly 11 of the automatic corner protection device adopts an innovative double silo structure design, which significantly improves the performance and efficiency of the strapping machine in corner protection processing.

[0061] 1. The storage chamber is tilted to ensure that the corner guards in the storage chamber are horizontal, so that the short corner guards can be stored closer to the corners of the materials. This can reduce the need to rotate the short corner guards due to mismatch in direction.

[0062] 2. Advantages of the double silo structure: By configuring the silo assembly 11 to include a first storage chamber 111 and a second storage chamber 112, the corner guard storage capacity of the device is significantly improved, specifically, the storage capacity is doubled. This design effectively avoids frequent shutdowns for refilling due to corner guard depletion, greatly reduces interruptions in the production process, and thus improves the overall working efficiency of the strapping machine.

[0063] 3. Function of the automatic feeding mechanism: In addition, the pushing mechanism in the device is carefully designed to automatically and efficiently feed the corner protectors 30 in the first storage chamber 111 and the second storage chamber 112. This automated feeding process not only improves the feeding speed and accuracy, but also further enhances the continuous operation capability of the production line.

[0064] 4. Compact structural design: Although the silo assembly 11 has a double silo structure, the overall design remains compact and occupies less space. This efficient and space-saving design allows the device to flexibly adapt to various working environments, especially in places with limited space, and still perform at its best.

[0065] Corner guard moving assembly

[0066] Also refer to Figure 6 and Figure 7 In this embodiment, the corner guard moving assembly 20 is a key part of the automatic corner guard device, which is responsible for accurately moving the corner guard 30 to the specified position. Figure 2 As shown, the corner guard moving assembly 20 includes a corner guard grabbing mechanism 21 , a lifting assembly 23 and a moving driving device 22 .

[0067] The corner guard grabbing mechanism 21 includes a first adsorption component 211, which is mounted on a mounting seat 212. When the corner guard 30 moves to the loading position, the first adsorption component 211 adsorbs the corner guard 30 on the first bearing part 1211 by the negative pressure generated, and then smoothly moves it to the discharge position, and releases the corner guard 30 at this position, so that it is accurately placed at the corner of the object to be packaged. Preferably, it includes two mounting seats 212 and two lifting components 23, and a gap 312 is left between the two mounting seats 212 for the strapping belt to pass through. Each mounting seat 212 is equipped with a first adsorption component 211, and the two mounting seats 212 are respectively connected to the output ends of the two lifting components 23, and the two lifting components 23 are mounted on the base 214. As an example, the lifting component 23 is a cylinder. When the corner guard is moved to the corner of the object to be packaged, the lifting component 23 drives the corner guard to move downward, so that the corner guard is closely attached to the corner of the material, making it easier to fit materials of various shapes and improving the packaging effect. Then, the strapping belt passes through the gap 312 between the two mounting seats 212, and moves downward during the tightening process, driving the corner protector to be closely attached to the corner of the object to be packed. This design ensures that the strapping belt can fix the corner protector in the correct position while tightening the object, thereby improving the stability and reliability of the packing.

[0068] The output end of the mobile drive device 22 is directly connected to the base 214 of the corner guard grabbing mechanism 21. The mobile drive device 22 is designed to control the corner guard grabbing mechanism 21 to move along a predetermined path between the material receiving position and the material discharge position. This action ensures that the corner guard can be accurately picked up from the first bearing part 1211 and correctly placed at the corner of the object to be packaged at the material discharge position. As an example, the mobile drive device 22 is a linear module with high precision and reliability.

[0069] Packing machine

[0070] refer to Figure 1 As shown, in another embodiment of the utility model, a baling machine is disclosed, including a vertical frame (not shown in the figure), a horizontal frame (not shown in the figure), a strapping head assembly (not shown in the figure) and the automatic corner protection device in the above embodiment, both ends of the horizontal frame are installed on the vertical frame and can be driven to move up and down, the strapping head assembly is installed on the horizontal frame, and the automatic corner protection device is installed on the horizontal frame.

[0071] In one embodiment, there are four automatic corner protection devices, and the four automatic corner protection devices are distributed in a rectangular shape.

[0072] The working principle of the automatic corner protection device for the baler of the utility model is as follows:

[0073] 1. Preparation stage: Before the operation begins, the staff needs to ensure that the first storage chamber 111 and the second storage chamber 112 are filled with stacked corner protectors to prepare for the subsequent automatic corner protection process.

[0074] 2. Loading stage: The pushing component 12 first loads the corner guards in the first storage chamber 111. During this process, the first sensing component controls the pushing drive component 122, so that the first bearing part 1211 moves accurately to just below the discharge port of the first storage chamber 111. Due to the action of the first counterweight 113, the bottom layer of corner guards falls to the surface 1211a of the first bearing part due to their own weight and the pressure of the counterweight. At the same time, the second suction cup component 123 starts and fixes these corner guards 30 by vacuum adsorption. Similarly, the bottom layer of corner guards 30 in the second storage chamber 112 will also fall onto the surface 1212a of the second bearing part. Then, the pushing drive component 122 drives the pushing member 121 to move and move the corner guards 30 to the material receiving position.

[0075] 3. Moving and unloading stage: The lifting assembly 23 extends to lower the first adsorption assembly 211 and fix the corner protector 30 on the first bearing part 1211 by vacuum adsorption. Then, the lifting assembly 23 is retracted to drive the first adsorption assembly 211 and the corner protector 30 to rise. At this time, the moving drive device 22 is started to move the corner protector 30 along the second direction ( Figure 1 The corner guard 30 is moved to the material discharging position (in the Y direction) and ensures that it is aligned with the corners of the object to be packaged. The lifting assembly 23 is lowered to make the corner guard close to the corner of the material. Then, the strapping head assembly is activated to place the corner guard 30 on the object to be packaged and perform vertical strapping.

[0076] 4. Repeat the operation and refill: The operator needs to repeat steps 1-3 until the first storage chamber 111 becomes empty. At this time, the pusher assembly 12 switches to the second storage chamber 112 for a similar loading process. When the second storage chamber 112 also becomes empty, manual refilling is performed. After refilling, the corner guard loading assembly 10 continues to repeat the above loading process.

[0077] By adopting a dual storage chamber design of a first storage chamber 111 and a second storage chamber 112, the device effectively increases the storage capacity of the corner protector 30, reduces the need for frequent shutdowns for refilling due to lack of the corner protector 30, and significantly improves the working efficiency of the strapping machine.

[0078] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
