Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor line mechanisms, and particularly relates to a double-chain roller conveyor with a stop-and-check mechanism. Background Art

[0002] The double-chain roller conveyor is a kind of logistics machinery and equipment, which is mainly suitable for transporting various types of boxes, bags, pallets, etc. Bulk materials, small items or irregular items need to be placed in pallets or turnover boxes for transportation. It adopts double-chain series drive, which has the characteristics of easy installation, stable performance, and large torque. The maximum conveying speed can reach 16m / min, which can meet the needs of fast transportation. The roller line is easy to connect and filter. Multiple rollers and other conveyors or special machines can be used to form a complex logistics transportation system. In situations where the weight of a single item is large, the conveying speed is fast, the conveying distance is required, and there are various complex process flows, the double-chain roller conveyor is the preferred model. The double-chain roller conveyor plays an important role in the field of logistics transportation due to its high efficiency and stability.

[0003] During use, in order to obtain the stop inspection time, the double-chain roller conveyor needs to pause to adapt to the output frequency of the previous device. The current conventional stopping method is to use mirror reflection photoelectricity, but this may not be able to stop normally due to photoelectric damage or dust, so optimization and improvement are needed. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a double-chain roller conveyor with a stop and inspection mechanism.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A double-chain roller conveyor with a stop-and-check mechanism comprises a machine body, side plates are symmetrically provided on both sides of the machine body, a plurality of rollers with sprockets are installed between the two side plates, the machine body drives all the rollers with sprockets to rotate to achieve the purpose of transfer, the two side plates are provided with curved waist-shaped holes corresponding to each other, the curved waist-shaped holes are located at the input end of the machine body, and rollers are placed together in the two curved waist-shaped holes, and the rollers are rotatably installed with stop-and-check rollers, and the diameter of the stop-and-check rollers is larger than the diameter of the rollers with sprockets;

[0007] Support plates are installed on the lower sides of the two side panels, contact strips are installed at both ends of the roller, a hinge shaft is installed in the middle section of the contact strip, the hinge shaft is installed on the side panel, a tension spring is installed between the contact strip and the support plate, a mounting frame is installed on the lower side of the side panel, a roller proximity switch is installed on the mounting frame, and the signal input end of the roller proximity switch is located within the moving range of the contact strip.

[0008] It is further defined that the diameter of the inspection stop roller is two centimeters larger than the diameter of the sprocket roller. This design ensures that it can contact the material before the sprocket roller and has a descending distance.

[0009] It is further defined that a reinforcement plate is installed at the position where the side panel is installed with the hinge shaft. Such a design ensures the load-bearing effect of the hinge shaft position and thus ensures the service life.

[0010] The beneficial effects of adopting the utility model are:

[0011] With the structural design of the utility model, when the machine body receives the material, the stop inspection roller contacts the material before the sprocket roller and moves downward under the gravity of the material. During the movement, the roller is guided by the curved waist-shaped hole, so that the contact bar rotates with an angle offset around the hinge shaft. During the rotation of the contact bar, physical contact is achieved with the roller proximity switch, and then a signal is given to the roller proximity switch, causing the machine body to start running. When the material moves away from the upper side of the stop inspection roller due to the rotation of the sprocket roller driven by the machine body, the stop inspection roller will return to its original position under the effect of the tension spring, causing the contact bar to leave the roller proximity switch, and the machine body stops running, thereby achieving the purpose of stop inspection.

[0012] With the structural design of the utility model, physical contact signal transmission does not have the problem of being stopped due to photoelectric damage or dust factors, thus ensuring the use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown, the utility model is a double-chain roller conveyor with a stop and inspection mechanism, comprising a machine body 1, with side plates 2 symmetrically provided on both sides of the machine body 1, a plurality of rollers with sprockets 3 installed between the two side plates 2, the machine body 1 drives all the rollers with sprockets 3 to rotate to achieve the purpose of transfer, the two side plates 2 are provided with curved waist-shaped holes 4 corresponding to each other, the curved waist-shaped holes 4 are located at the input end of the machine body 1, and rollers 5 are placed together with the curved waist-shaped holes 4, and the rollers 5 are rotatably installed with stop and inspection rollers 6, and the diameter of the stop and inspection rollers 6 is larger than the diameter of the rollers with sprockets 3;

[0022] Support plates 7 are installed on the lower sides of the two side panels 2, contact strips 8 are installed at both ends of the roller 5, a hinge shaft 9 is installed in the middle section of the contact strip 8, the hinge shaft 9 is installed on the side panel 2, a tension spring 10 is installed between the contact strip 8 and the support plate 7, a mounting frame 11 is installed on the lower side of the side panel 2, a roller proximity switch 12 is installed on the mounting frame 11, and the signal input end of the roller proximity switch 12 is located within the moving range of the contact strip 8.

[0023] In this embodiment, when a double-chain roller conveyor with a stop-check mechanism is used, the material enters the machine body 1 from one end of the machine body 1 where the stop-check roller 6 is installed. When the material enters, because the diameter of the stop-check roller 6 is larger than the diameter of the roller with sprocket 3, the stop-check roller 6 contacts the material before the roller with sprocket 6. Under the contact of the material and the weight of the material, the material will press the stop-check roller 6 to move downward, and under the effect of the curved waist-shaped hole 4, the roller 5 will perform an arc-shaped movement. Under this movement, the contact strip 8 installed on the roller 5 rotates with the hinge shaft 9 as the axis, and the other end of the contact strip 8 approaches the direction of the roller-type proximity switch 12 and contacts the roller-type proximity switch 12, giving the roller-type proximity switch 12 a signal, and the machine body 1 runs, controlling the rotation of the sprocket roller 3 to transfer the material.

[0024] When the material moves away from the upper side of the stop-inspection roller 6, the upper side of the stop-inspection roller 6 is no longer subjected to force. Under the effect of the tension spring 10, the contact bar 8 is pulled away from the roller proximity switch 12 and moves toward the support plate 7. Then, the machine body 1 is no longer affected by the signal transmitted by the roller proximity switch 12, and the rotation of the sprocket roller 3 is stopped, thereby stopping the conveying of the material and achieving the purpose of stopping the inspection.

[0025] Preferably, the diameter of the inspection roller 6 is two centimeters larger than the diameter of the sprocket roller 3. This design ensures that it can contact the material before the sprocket roller 3 and has a descending distance. In fact, the diameter of the inspection roller 6 can also be considered according to specific circumstances.

[0026] Preferably, a reinforcement plate 13 is installed at the position where the hinge shaft 9 is installed on the side panel 2. Such a design ensures the load-bearing effect of the hinge shaft 9 position and thus ensures the service life. In fact, the installation structure of the hinge shaft 9 can also be considered according to specific circumstances.

[0027] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
