Description

Technical Field

[0001] The invention relates to the technical field of palletizing clamps, in particular to a palletizing clamp for producing wooden boxes. Background Art

[0002] Wooden boxes are plastic rectangular packaging containers made of wood, bamboo or wood mixed materials. Wooden boxes are the oldest packaging containers and one of the important transportation packaging containers. They need to be transported and stacked during the production process.

[0003] In the prior art, wooden boxes are generally fixedly clamped by clamps, and are transported and stacked in conjunction with movable lifting equipment. However, since the wooden boxes themselves have a certain weight, a certain load will be generated each time the clamp is clamped and transported, resulting in a certain degree of wear and tear on the clamp itself, affecting the service life of the clamp. When the wear and tear of the clamp reaches a certain level, the wooden box cannot be effectively clamped. At this time, the wooden box is very likely to fall during the clamping process, posing a safety hazard to surrounding staff. Since different wooden boxes have different weights, staff cannot judge when the clamp has been worn out to the point of being unusable. Therefore, they can only replace the clamp at an approximate time, which poses a great safety hazard to the clamp during use. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that workers are unable to replace the fixture in time when the fixture is worn out to the point where it cannot be used, and to propose a stacking fixture for wooden box production.

[0042] 3. The present invention uses the inclined surface of the anti-falling plate and the inclined surface of the contact plate to guide the falling wooden box to slide inward under the action of gravity. This prevents the wooden box from falling from the anti-falling plate due to the displacement of the center of gravity caused by a violent collision with the anti-falling plate. This helps to ensure the anti-falling effect of the anti-falling plate.

[0043] 4. The present invention utilizes a shock-absorbing mechanism to buffer and protect the force generated when the wooden box contacts the anti-fall plate, and consumes the force generated by the fall of the wooden box through the mutual squeezing and friction of sand, and synchronously drives the driven rack to move upward and resist the anti-fall plate, thereby limiting the movement range of the anti-fall plate, which helps to reduce the impact force of the wooden box on the anti-fall plate.

[0061] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0062] The present invention provides the following preferred embodiments:

[0063] Embodiment 1

[0064] refer to Figure 2 and Figure 3 As shown, this embodiment provides a palletizing fixture for wooden box production, the palletizing fixture includes a horizontal displacement mechanism 1, a mounting plate 2 and a telescopic clamping plate 3, and the components are arranged as follows:

[0065] The mounting plate 2 is used to mount the horizontal displacement mechanism 1, and the telescopic clamping plate 3 is mounted on the horizontal displacement mechanism 1. The telescopic clamping plate 3 is driven by the horizontal displacement mechanism 1 to move horizontally toward each other, thereby achieving the purpose of fixing and clamping the wooden box.

[0066] A further implementation method is that the horizontal displacement mechanism 1 comprises:

[0067] The mounting groove 101 is opened on the mounting plate 2, the motor 102 is installed on the mounting plate 2, the bidirectional lead screw 103 is rotatably installed in the mounting groove 101, and the moving slider 104 is installed on the bidirectional lead screw 103. Two moving sliders 104 are provided. After the bidirectional lead screw 103 rotates, the two moving sliders 104 will move horizontally towards each other. A nut matched with the bidirectional lead screw 103 is provided in the moving slider 104, and the moving slider 104 is fixedly connected to the telescopic clamping plate 3.

[0068] The telescopic clamping plate 3 is used to fix and clamp the wooden box. The side of the telescopic clamping plate 3 that is against the wooden box is fixedly connected with memory foam. The memory foam refers to a polyether polyurethane foam sponge with slow rebound mechanical properties. The memory foam is used to contact the wooden box to achieve flexible clamping of the wooden box by the telescopic clamping plate 3, which helps to avoid damage to the surface of the wooden box. The telescopic clamping plate 3 is composed of a first hollow plate 301, a second hollow plate 302 and a driving cylinder 303. The driving cylinder 303 is installed in the first hollow plate 301, and the output end of the driving cylinder 303 is connected to the second hollow plate 302. The driving cylinder 303 makes the second hollow plate 302 have telescopic performance, so as to match wooden boxes of different specifications and different positions. The second hollow plate 302 is an L-shaped structure. Therefore, the telescopic clamping plate 3 is clamped on three sides when fixing and clamping the wooden box, which helps to increase the clamping area between the telescopic clamping plate 3 and the wooden box, thereby ensuring the clamping effect of the clamp.

[0069] It should be noted that the specific models and specifications of the motor 102 and the driving cylinder 303 need to be selected and determined according to the actual specifications of the fixture, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0070] When using the palletizing fixture for wooden box production, follow the steps below:

[0071] Start the driving cylinder 303, which drives the second hollow plate 302 to move outward, so that the second hollow plate 302 moves to the two sides of the wooden box that needs to be clamped, and start the motor 102, which drives the bidirectional lead screw 103 to rotate. At this time, the two movable sliders 104 move horizontally toward each other on the bidirectional lead screw 103, and the two movable sliders 104 drive the telescopic clamping plate 3 to fix and clamp the wooden box.

[0072] Embodiment 2

[0073] refer to Figures 4 to 5 As shown, on the basis of the first embodiment, in order to prevent the wooden box from falling directly when the telescopic clamping plate 3 loses its fixing effect, the limiting plate 4, the support member 5 and the anti-falling plate 6 are introduced in the embodiment, and the anti-falling plate 6 is used to block and receive the wooden box when it falls. The specific implementation method is as follows:

[0074] The limit plate 4 is installed on the mounting plate 2 , the support member 5 is installed on the limit plate 4 , at least four support members 5 are provided, the anti-falling plate 6 is installed on the support member 5 , and a resistance plate 7 is provided at the lower end of the mounting plate 2 .

[0075] The upper surface of the anti-falling plate 6 is inclined toward the mounting plate 2, and the contact plate 7 is inclined close to the side of the anti-falling plate 6, and the inclined surface of the contact plate 7 is at a right angle to the inclined surface of the anti-falling plate 6, so that when the wooden box falls onto the anti-falling plate 6, it will move toward the contact plate 7 under the action of gravity, thereby preventing the wooden box from tipping forward.

[0076] When using the palletizing fixture for wooden box production, follow the steps below:

[0077] After the wooden box falls, it impacts the anti-falling plate 6 , and under the action of gravity, the wooden box is guided by the inclined surface of the anti-falling plate 6 and flexibly abuts against the abutment plate 7 .

[0078] Embodiment 3

[0079] refer to Figure 1 and Figures 6 to 8 As shown, on the basis of the second embodiment, in order to avoid the violent collision between the anti-falling plate 6 and the wooden box, which may cause the wooden box to be easily unstable and separated from the anti-falling plate 6, a shock absorbing mechanism 8 is introduced, and the support member 5 is further refined. The support member 5 is composed of a movable sleeve 501, a movable rod 502, a piston plate 503 and a support spring 504. The specific implementation method is as follows:

[0080] The movable sleeve 501 is installed on the limit plate 4, the movable rod 502 is slidably mounted in the movable sleeve 501, and the piston plate 503 is connected to one end of the movable rod 502 located in the movable sleeve 501. The sliding connection between the movable sleeve 501 and the movable rod 502 makes the support member 5 retractable. The support spring 504 is connected between the piston plate 503 and the movable sleeve 501. Through the elastic force of the support spring 504, the support member 5 will be reset under the elastic force of the support spring 504 after being stressed, and the anti-falling plate 6 is elastically supported by the movable rod 502 and the piston plate 503, so that the anti-falling plate 6 maintains a balanced state when not affected by external force. The shock absorbing mechanism 8 is arranged on the anti-falling plate 6.

[0081] The shock absorbing mechanism 8 is used to buffer the force generated by the falling of the wooden box and warn the staff to replace the telescopic clamping plate 3.

[0082] A further implementation method is that the shock absorbing mechanism 8 comprises:

[0083] The driving rack 801 installed on the anti-falling plate 6 extends to the position below the limiting plate 4. The anti-falling plate 6 is provided with a first movable opening for movable assembly of the driving rack 801. The first movable opening provides a movable space for the vertical movement of the driving rack 801, thereby limiting the movement trajectory of the driving rack 801, so that the movement trajectory of the driving rack 801 is single.

[0084] The bracket 802 is installed on the lower surface of the anti-falling plate 6, and the driven gear 803 installed on the bracket 802 is rotatable, so that the driving rack 801 is meshed with the driven gear 803, and the driven rack 804 is slidably installed on the limit plate 4. The driven rack 804 is meshed and connected with the driven gear 803. The anti-falling plate 6 is provided with a second movable opening for movably fitting the driven rack 804, and the second movable opening is used to provide a movable space for the vertical movement of the driven rack 804, thereby limiting the movement trajectory of the driven rack 804, so that the movement trajectory of the driven rack 804 is single, and the driven rack 804 is provided with a guide groove 8041, and the guide groove 8041 is slidably fitted with a guide slider 8042 fixedly connected to the second movable opening, through the guide groove 8041 The sliding connection with the guide slider 8042 ensures that the driven rack 804 will not be suspended in the air, and a friction plate is provided between the guide slot 8041 and the guide slider 8042, and a return spring 8043 is fixedly connected between the guide slider 8042 and the guide slot 8041. The friction plate increases the friction resistance between the guide slot 8041 and the guide slider 8042, and the return spring 8043 provides elastic support for the driven rack 804, so as to prevent the driven rack 804 from moving when it is not affected by external force. At least three rubber balls are provided at the top of the driven rack 804, so that the top of the driven rack 804 is in flexible contact with the anti-fall plate 6, which helps to avoid greater wear caused by the meshing connection between the driven rack 804 and the driven gear 803.

[0085] The buffer box 805 is installed at the bottom end of the limiting plate 4. The buffer box 805 is filled with sand. The resistance ball 806 is movably mounted on the limiting plate 4. The lower end of the resistance ball 806 is located in the buffer box 805. The anti-falling plate 6 squeezes the resistance ball 806, so that the force generated between the wooden box and the anti-falling plate 6 will indirectly act on the resistance ball 806, and at this time the resistance ball 806 will squeeze the sand, and the sand particles will rub and collide with each other, thereby consuming the force transmitted by the resistance ball 806.

[0086] The installation cavity 807 is opened on the top of the contact ball 806, the squeezing ball 808 is embedded in the upper end of the installation cavity 807, the pressure sensor 809 is fixedly installed on the bottom of the installation cavity 807, and the alarm 810 is installed on the limit plate 4. The alarm 810 is electrically connected to the pressure sensor 809, and the alarm 810 is equipped with a buzzer. The squeezing ball 808 will come into contact with the anti-fall plate 6 before the contact ball 806. The squeezing ball 808 will move downward under the force and exert a force on the pressure sensor 809. At this time, by monitoring the output signal change of the pressure sensor 809, the alarm 810 is started, flashing a red light and making a sharp sound through the buzzer, thereby alerting the surrounding staff that the wooden boxes have fallen during the stacking process, so that the staff can find the problem in time and take corresponding measures.

[0087] When using the palletizing fixture for wooden box production, follow the steps below:

[0088] During the falling process of the wooden box, the anti-fall plate 6 drives the movable rod 502 to move downward, and the movable rod 502 drives the piston plate 503 to move downward, and the piston plate 503 squeezes the support spring 504;

[0089] The anti-falling plate 6 drives the driving rack 801 to move vertically downward, the driving rack 801 drives the driven gear 803 to rotate, and the driven gear 803 drives the driven rack 804 to move upward, so that the rubber ball on the driven rack 804 conflicts with the anti-falling plate 6, thereby preventing the anti-falling plate 6 from moving further downward, thereby limiting the falling range of the anti-falling plate 6;

[0090] At the same time, the anti-fall plate 6 drives the squeezing ball 808 to move downward, and the squeezing ball 808 squeezes the pressure sensor 809. At this time, the alarm 810 starts to warn the staff. The anti-fall plate 6 drives the resistance ball 806 to move downward, and the resistance ball 806 will squeeze the sand in the buffer box 805.

[0091] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
