Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1, an embodiment of the present invention includes:

a stacker hold down apparatus, the stacker hold down apparatus comprising: the detection frame 18 is fixed on the cargo carrying table 17, the pressing mechanism is installed on the upper portion of the detection frame 18, the pressing mechanism comprises a pressing plate 13 and a pressing plate support 7, the pressing plate 13 is installed on the pressing plate support 7, the pressing plate support 7 is installed on a pressing plate track laid in advance, the pressing plate track comprises a wire rail 3 and a wire rail installation plate 2, the wire rail installation plate 2 is installed on the cargo carrying table 17, the wire rail 3 is installed on the wire rail installation plate 2, and the wire rail installation plate 2 is continuously laid on the cargo carrying table 17 and the detection frame 18; the goods loading platform 17 and the detection frame 18 are provided with a chain wheel transmission mechanism, and the chain wheel transmission mechanism is connected with the pressing plate support 7 and can drive the whole pressing mechanism to move up and down along the linear rail 3.

The chain wheel transmission mechanism comprises a driving structure, a bottom chain wheel 1, a top chain wheel 12 and a transmission chain, the driving structure comprises a driving motor 9 and a transmission shaft 10, the driving motor 9 is fixed on the upper part of the detection frame 18, the driving motor 9 is connected with the transmission shaft 10 through a motor reducer, two ends of the transmission shaft 10 are fixed on the detection frame 18 through a bearing with a seat 8, the end position of the transmission shaft 10 is fixedly provided with a top chain wheel 12, the bottom chain wheel 1 is fixed on a cargo carrying platform, the transmission chain is connected with the bottom chain wheel 1 and the top chain wheel 12, the pressing plate bracket 7 is connected with the transmission chain together, when the driving motor 9 is started, the top chain wheel 12 and the bottom chain wheel 1 can be driven to synchronously rotate under the action of the transmission chain, and when the transmission chain moves, the pressing plate bracket 7 can be dragged to vertically move up and down along the linear rail 3.

The middle of the pressing plate 13 is provided with a position sensor 14, the goods carrying platform 18 is further provided with a drag chain mounting plate 4, one end of a drag chain 16 is installed on the drag chain mounting plate 4, one end of the drag chain is connected with the pressing plate support 7, a drag chain cable is installed in the drag chain 16, one end of the drag chain cable is connected with the position sensor 14 through the pressing support 7, and the other end of the drag chain cable is connected with a driving motor 9 of the chain wheel transmission mechanism. The position sensor 14 can position the top position of goods in advance when carrying out the action of compressing tightly, then according to the position control driving motor's of goods top stroke, prevents to compress tightly in-process clamp plate 13 motion range too big, leads to the too big damage clamp plate 13 of effort or goods between clamp plate and the goods surface. The clamp plate 13 is installed buffer 15 towards the one side of carrying cargo bed 17, buffer 15's effect mainly prevents that the too fast face that leads to clamp plate 13 when clamp plate 13 pushes down from directly colliding the goods of placing on the tray 19 of carrying cargo bed 17, leading to goods or clamp plate 13 damage. Still install tow chain overspeed device tensioner 6 between the chain head of compressing tightly support and tow chain, sensitivity and synchronization degree when improving the tow chain 16 and dragging prevent to lead to the tow chain cable to be injured when the tow chain motion. The detection frame 17 is also provided with a drag chain guide frame 5, the drag chain guide frame 5 is used for combing the drag chain 16, and the drag chain 16 is prevented from shaking left and right due to the flexibility of the drag chain when the pressing plate 13 moves up and down and being damaged due to the fact that the drag chain touches the pressing mechanism. Detect frame 17 top and still install sprocket safety cover 11, sprocket safety cover 11's effect prevents in dust debris gets into the top sprocket, influences the lubrication.

The operation principle of the technical scheme is as follows: when goods are placed on a tray 19 of a goods carrying table 17, firstly, the height of the top of the goods is determined by a position sensor 14, then, the height information is fed back to a controller of a driving motor 9, the driving motor 9 is controlled by the controller of the driving motor to start working, a transmission shaft 10 is driven to rotate through a speed reducer, then the transmission shaft 10 drives a whole top chain wheel 12 and a bottom chain wheel 1 to rotate simultaneously, the rotation of the chain wheels drives a transmission chain to move, and the transmission chain drags a pressing plate support to drive a pressing plate 13 to move downwards for a corresponding distance, so that the function of pressing the goods is realized.

In practical use, the height of the goods placed on the goods carrying platform 17 is detected through the detection frame 18, then the pressing plate 13 is pressed on the top of the goods through the action of the external control equipment for controlling the drag chain 16, and after the stacker reaches a specified position, the pressing plate 13 is quickly lifted, so that the loss of materials caused by the fact that the goods are scattered in the movement of the goods carrying platform 17 due to the fact that the operation speed is too high or the whole package of the goods is too loose is reduced.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
