Description

Technical Field

[0001] This utility model relates to the field of plate-stacking machine components, and in particular to a plate-stacking machine clutch device. Background Technology

[0002] Existing tray-loading machines include an empty tray area, a working area, and a tray-loading area. When the tray moves to the working area, its movement needs to stop to allow workers sufficient time to process the workpieces. Current tray-loading machines primarily control this part in two ways: one is by adding a clutch to the motor, which is costly, complex, and prone to frequent starts and stops, resulting in a high failure rate; the other is by installing a drive cylinder at the tray frame to lift the tray, detaching it from the continuously moving conveyor belt. However, the trays carrying workpieces are generally heavy, and the frequent lifting causes significant energy consumption. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a clutch device for a swivel plate machine. The specific design scheme is as follows:

[0004] A disc swivel machine clutch device includes a conveyor belt, which has a ring structure. A pressure roller is provided above the conveyor belt, and a tension roller is provided in the middle of the ring structure of the conveyor belt. The conveyor belt is mounted on a base frame. The conveyor belt, pressure roller, and tension roller are all mounted on the base frame, and a support frame is provided in the middle of the base frame.

[0005] The number of conveyor belts is two, which are distributed left and right and fixed on the two sides of the rectangular frame structure of the base frame. Each conveyor belt is a ring structure and is equipped with a pressure roller and a tension roller. The two conveyor belts are driven by the same motor and are driven by a transmission shaft. The left and right ends of the material tray are mounted on the two conveyor belts.

[0006] The pressure roller moves up and down via a drive cylinder, which is fixedly connected to the roller frame of the pressure roller via a mounting plate at the end of its cylinder shaft.

[0007] The pressure roller is mounted on the base frame via a first angle steel. Specifically, the cylinder body of the drive cylinder is fixed to the first angle steel, which is mounted on the base frame.

[0008] The height of the pressure roller when it is raised is higher than the height of the material tray when it is on the conveyor belt. This structure ensures that the pressure roller does not obstruct the normal conveying of the material tray on the conveyor belt, and the return spring of the tension roller is in a relaxed state.

[0009] When the pressure roller presses down, the bottom surface of the material tray located on the conveyor belt is mounted on the pallet frame. This structure ensures that the material tray and the conveyor belt can be engaged and disengaged without starting or stopping the motor, and the return spring of the tension roller is in a compressed state.

[0010] The tensioning roller is connected to the base frame via a second angle steel. Specifically, the roller seat of the tensioning roller is connected to the second angle steel, and the second angle steel is fixedly connected to the base frame.

[0011] There are multiple pressure rollers and tension rollers, which are arranged in a straight array in the conveying direction of the conveyor belt. However, no pressure rollers are installed on the conveyor belt on the left and right sides of the pallet frame to avoid the pressure rollers pressing on the material tray during operation.

[0012] A position sensor is installed on the base frame. The position sensor is used to confirm the position of the material tray, thereby confirming the timing of the drive cylinder driving the pressure roller to perform the clutch function.

[0013] The beneficial effects of the swivel plate machine clutch device obtained by the above-described technical solution of this utility model are as follows:

[0014] It does not require stopping the conveyor belt or lifting heavy pallets, resulting in a low failure rate, low modification costs, and energy savings. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] A disc swivel machine clutch device includes a conveyor belt 1, which has a ring structure. A pressure roller 2 is provided above the conveyor belt 1, and a tension roller 3 is provided in the middle of the ring structure of the conveyor belt 1. The conveyor belt 1 is mounted on a base frame 5. The conveyor belt 1, the pressure roller 2, and the tension roller 3 are all mounted on the base frame 5. A tray frame 6 is provided in the middle of the base frame 5.

[0023] There are two conveyor belts 1, which are distributed left and right and fixed on the two sides of the rectangular frame structure of the base frame 5 respectively. Each conveyor belt 1 has a ring structure and each conveyor belt is equipped with a pressure roller 2 and a tension roller 3. The two conveyor belts are driven by the same motor 7 and the transmission is realized through the transmission shaft 8. The left and right ends of the material tray 9 are mounted on the two conveyor belts 1.

[0024] The pressure roller 2 moves up and down through a drive cylinder 10, which is fixedly connected to the wheel frame 11 of the pressure roller 2 via a mounting plate 12 at the end of its cylinder shaft.

[0025] The pressure roller 2 is mounted on the base frame 5 via the first angle steel 13. Specifically, the cylinder body of the drive cylinder 10 is fixed on the first angle steel 13, and the first angle steel 13 is mounted on the base frame 5.

[0026] The height of the pressure roller 2 when it is raised is higher than the height of the material tray 9 when it is on the conveyor belt 1. This structure ensures that the pressure roller 2 does not obstruct the normal conveying of the material tray 9 on the conveyor belt 1, and the return spring of the tension roller 3 is in a relaxed state.

[0027] When the pressure roller 2 presses down, the bottom surface of the material tray 9 located on the conveyor belt 1 is mounted on the pallet frame 6. This structure ensures that the material tray 9 can be engaged or disengaged from the conveyor belt 1 without starting or stopping the motor 7, and the return spring of the tension roller 3 is in a compressed state.

[0028] The tensioning roller 3 is connected to the base frame 5 via the second angle steel 14. Specifically, the roller seat 15 of the tensioning roller 3 is connected to the second angle steel 14, and the second angle steel 14 is fixedly connected to the base frame 5.

[0029] There are multiple pressure rollers 2 and tension rollers 3. The multiple pressure rollers 2 and tension rollers 3 are arranged in a straight array in the conveying direction of the conveyor belt 1. However, pressure rollers 2 are not set on the conveyor belt 1 on the left and right sides of the pallet frame 6 to avoid the pressure rollers 2 pressing on the material tray 9 during operation.

[0030] A position sensor 4 is installed on the base frame 5. The position sensor 4 is used to confirm the position of the material tray 9, thereby confirming the timing of the drive cylinder 10 driving the pressure roller 2 to perform the clutch function.

[0031] To ensure the clutch function is realized, the length of the conveyor belt 1 is greater than the length of the conveyor belt 1 that the swivel machine should have, and it is tensioned by multiple tension rollers 3 to ensure the flatness of the conveyor belt when the material tray 9 is loaded.

[0032] When the material tray 9 moves from the control area or the tray area to above the unloading rack 6, the drive cylinder 10 is activated. The cylinder shaft of the drive cylinder 10 pushes the pressure roller 2 downward. After the pressure roller 2 reaches the conveyor belt 1, it continues to press down, causing the conveyor belt 1 to deform. At this time, the material tray 9 will also move down with the deformation of the conveyor belt 1 and be mounted on the pallet rack 6. During the deformation process, the lower part of the annular structure of the conveyor belt 1 will also deform. At the same time, the tension roller 3 is pressed and contracted. At this time, the operator can start working on the material tray 9. Meanwhile, the conveyor belt does not stop, but continues to rotate under the drive of the motor 7. The wheel body of the pressure roller 2 and the roller body of the tension roller 3 will also rotate.

[0033] After the workpiece operation is completed, the cylinder shaft of the drive cylinder 10 is reset, the pressure roller 2 moves upward, the tension roller 3 is reset based on the spring force of the torsion spring, the conveyor belt 1 is reloaded and lifts the material tray 9, and the material tray 9 is transported. At this time, the material tray 9 is transported through the gap between the pressure roller 2 and the conveyor belt 1, completing one tray-swing operation.

[0034] Based on the existing plate-slab machine, prepare readily available accessories such as angle steel, pressure roller 2, tension roller 3, and mounting plate. Without changing the existing plate-slab machine structure, the modification can be directly installed and modified, resulting in low modification costs and even eliminating the need to remove the original clutch device of the plate-slab machine.

[0035] The mounting holes on the base frame 5 for mounting the second angle steel 14 and the mounting holes on the first angle steel 13 for mounting the drive cylinder 10 are preferably long holes in the vertical direction, which facilitates the adjustment of the height of the pressure roller 2 and the tension roller 3.

[0036] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
