Description

Technical Field

[0001] The utility model relates to the technical field of transfer machines, and particularly relates to a clamping device for a roller assembly line transfer machine. Background Art

[0002] A transfer machine is an efficient automatic handling device. It uses a transfer cart to slide on a guide rail, and can quickly transport a load from one station to another. At the same time, according to actual needs, it can also conveniently flip the load. It is an important device on an automated production line.

[0003] In industrial production, a roller assembly line is a commonly used, efficient, and mature device. Product turnover often requires moving positions, or the packaged goods need to be moved to a transfer pallet. In actual production, it often requires two or more people to carry. In order to reduce labor costs and labor intensity, it is necessary to provide a semi-automatic transplanting device that is easy to operate and economically applicable in the case of not using fully automated production. Summary of the Utility Model

[0004] Purpose of the utility model: In order to overcome the above deficiencies, the purpose of the present utility model is to provide a clamping device for a roller assembly line transfer machine, which has a simple structure, is convenient to operate, is reasonably designed, no longer requires manual handling, and reduces labor costs and labor intensity.

[0005] Technical solution: In order to achieve the above purpose, the present utility model provides a clamping device for a roller assembly line transfer machine, including a lifting rod and a clamping device. The lifting rod is connected to the clamping device. The clamping device includes a frame, a fixed clamping plate, and a movable clamping device. The fixed clamping plate is fixedly installed on the frame. The movable clamping device is slidably installed on the frame and can move closer to or away from the fixed clamping plate in a direction parallel to the axis of the roller. A pallet claw is provided at the free end of the movable clamping device away from the frame. The pallet claw also has a yielding recess that allows it to sink into the gap between adjacent rollers.

[0006] Furthermore, the movable clamping device further includes a set of parallel clamping rods. The lower part of the clamping rods is connected to the pallet claw. The pallet claw is L-shaped; there are multiple teeth between the yielding recesses; the yielding recesses are covered with an elastic material, and the teeth are inclined upward. The L-shaped pallet claw can play a role in lifting the goods, and the setting of the yielding recess allows the pallet claw to extend into the gap between the rollers and lift the goods from the bottom. The elastic material is provided at the yielding recess to prevent the clamping device from damaging the rollers when moving downward, and also to use the friction of the buffer material to keep the rollers stationary.

[0007] Further, the fixed clamping plate is bent. The upper part of the fixed clamping plate is fixedly connected to the frame, and the lower part is elastically bent inward. The fixed clamping plate is made of spring steel sheet. The fixed clamping plate cooperates with the movable clamping device to elastically clamp the goods, ensuring the firmness of the goods clamping and not damaging the goods. On the other hand, when unloading, the clamping device will not be stuck by the goods when the goods on the pallet are placed in multiple rows.

[0008] Further, a clearance tooth is provided at the bottom of the fixed clamping plate. The clearance tooth can extend into the clearance between the rollers. An anti-slip damping plate is provided on the inner side of the fixed clamping plate. The anti-slip damping plate increases the frictional resistance and prevents the goods from falling off.

[0009] Further, a driving device and a slide rail are provided on the frame. A group of parallel cross beams are slidably arranged on the slide rail. The driving device is connected to the two cross beams. The upper part of the clamping rod is slidably connected between the two cross beams. Under the action of the driving device, the cross beam can move back and forth on the slide rail, thereby driving the clamping rod. The clamping rod is arranged between the cross beams, and the position of the clamping rod on the cross beam can be changed. By selecting a pallet claw of a suitable size and installing it on the clamping rod, its clamping range can be adjusted.

[0010] Furthermore, the other end of the lifting rod is connected to a traveling electric hoist. The driving device is a cylinder. The cylinder is installed on the frame and is connected to the upper part of the movable clamping device.

[0011] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0012] 1. A clamping device for a roller conveyor line transfer machine disclosed by the present utility model has a simple structure and a simple and efficient operation method. The goods are clamped and transferred by the cooperation of the movable clamping rod and the fixed clamping plate, reducing labor costs and labor intensity, and being suitable for fully automated production.

[0013] 2. The clamping device disclosed in the present utility model, wherein the movable clamping rod can change its clamping range, with a wider application range. The fixed clamping plate is made of spring steel and is bent inward, which can not only ensure the firmness of the goods clamping but also not damage the goods. At the same time, when the goods are placed in multiple rows, the slightly bent shape can prevent the clamping device from being unable to take out the goods after placement.
