Description

Technical Field

[0001] The present application relates to the technical field of cigarette production, and more specifically, to a detection device for the door switch of a case turnover machine. Background Art

[0002] During the case turnover process of the case turnover machine, a door opening and closing device is used to control the turnover of materials in the case. The door opening and closing device includes an electrical detection element. The electrical detection element controls the opening angle of the case door according to the demand for the supply of different materials during the production process, and determines the opening and closing states of the case door through the in-place signal of the electrical detection element.

[0003] Currently, the case turnover machine mainly uses a motor to drive a push rod to perform the door opening and closing actions in a push-pull manner. Specifically, a magnetic detection element is provided outside the push rod, and a ferromagnetic element is provided inside the push rod. When the magnetic detection element recognizes the ferromagnetic element, the case door reaches the open or closed state. However, such a structure requires the magnetic detection element and the ferromagnetic element to maintain effective magnetism and not have relative displacement to meet the working requirements. However, the ferromagnetic element is prone to demagnetization during use.

[0004] An improved solution is to replace the magnetic detection element with a U-shaped phototube. The U-shaped phototube is fixed on the central axis of the door opening and closing, and a detection blocker is installed at the corresponding position of the door opening and closing. The opening and closing of the case door are detected and controlled by whether the blocker blocks the U-shaped phototube.

[0005] However, the blocker is prone to deformation, and the U-shaped phototube may be blocked by materials and cause false triggering, which easily damages the detection element and affects production efficiency. Summary of the Invention

[0006] The present application provides a detection device for the door switch of a case turnover machine.

[0029] The present application provides a door switch detection device for a turnover box machine. The door opening trigger and the door closing trigger are arranged outside the trajectory of the material. The door opening control is achieved by detecting the door opening trigger by the door opening proximity switch, and the door closing control is achieved by detecting the door closing trigger by the door closing proximity switch, avoiding the phenomenon of false triggering caused by material occlusion. At the same time, the split detection ensures the control accuracy of the box door.

[0030] As Figures 1 - 3 shown, a box door (shown as two box doors in the figure) is rotatably provided on the first side surface 101 of the turnover box machine. Taking the left box door 104 as an example, the door shaft of the box door 104 is rotatably provided on the edges of the first side surface 101 and the second side surface 102. The door switch detection device of the turnover box machine provided by the present application includes a door opening trigger 9, a door closing trigger 4, a door opening proximity switch 2, and a door closing proximity switch 1.

[0031] The door opening trigger 9 and the door closing trigger 4 respectively protrude from the edge of the box door 104 and are detachably connected to the box door 104. The movement planes of the door opening trigger 9 and the door closing trigger 4 are parallel to the third side surface 103 of the box door 104, and the third side surface 103 is perpendicular to the door shaft.

[0032] Specifically, an L-shaped bracket 8 is fixed on the box door 104. The first right-angled side of the L-shaped bracket 8 is fixed on the outer side surface of the box door 104, and the second right-angled side of the L-shaped bracket 8 protrudes from the edge of the box door 104 and is parallel to the third side surface 103 of the turnover machine (as Figure 2 shown), and the door-opening trigger 9 and the door-closing trigger 4 are respectively detachably connected to the second right-angled side of the L-shaped bracket 8.

[0033] As Figure 1 shown, the door-closing trigger 4 is L-shaped. The first right-angled side of the door-closing trigger 4 is perpendicular to the box door and is fixedly connected to the second right-angled side of the L-shaped bracket 8 through the third bolt 7. The second right-angled side of the door-closing trigger 4 is parallel to the box door and faces the second side surface 102, and the plane where the door-closing trigger 4 is located is parallel to the third side surface 103.

[0034] The plane where the door-opening trigger 9 is located is parallel to the third side surface 103, and the door-opening trigger 9 is rectangular.

[0035] Preferably, the included angle between the door-opening trigger 9 and the box door 104 is adjustable.

[0036] Specifically, as Figure 1 shown, the first corner of the door-opening trigger 9 is fixedly connected to the second right-angled side of the L-shaped bracket 8 through the first bolt 5, and the second corner of the door-opening trigger 9 is fixedly connected to the second right-angled side of the L-shaped bracket 8 through the second bolt 6. The first corner and the second corner are adjacent. An arc-shaped chute is provided on the second right-angled side of the L-shaped bracket 8. The center of the arc-shaped chute is the installation point of the first bolt 5, and the second bolt 6 is fixed on the arc-shaped chute. By loosening the second bolt 6, the second bolt 6 can move within the arc-shaped chute, that is, the position movement range of the second bolt 6 is the arc-shaped chute. By changing the position of the second bolt 6 on the arc-shaped chute, the included angle between the door-opening trigger 9 and the box door 104 can be changed, so as to change the maximum opening angle of the box door 104.

[0037] The door-opening proximity switch 2 and the door-closing proximity switch 1 are fixedly spaced on the second side surface 102 of the turnover machine, and the detection heads of both face the third side surface 103 of the box door. As Figure 1 shown, the arrangement direction of the door-opening proximity switch 2 and the door-closing proximity switch 1 is perpendicular to the door shaft.

[0038] Specifically, as Figure 3As shown, a switch bracket 3 is fixedly provided on the second side surface 102, and the switch bracket 3 includes two L-shaped bases that are fixedly connected and parallel to each other, and the first right-angled sides of the two L-shaped bases are fixedly connected to each other and to the second side surface 102 (for example, by welding), and the door opening proximity switch and the door closing proximity switch are respectively fixed in the right-angle space formed by the two L-shaped bases. The second right-angled sides of the two L-shaped bases are respectively fixedly connected to the junction boxes of the door opening proximity switch and the door closing proximity switch by bolts.

[0039] Preferably, the switch bracket 3 is made of steel plate.

[0040] As an embodiment, the door opening proximity switch and the door closing proximity switch are Pepperl+Fuchs square proximity switches, which are non-contact switches.

[0041] like Figure 1 and 3 As shown, compared with the door closing proximity switch 1, the door opening proximity switch 2 is closer to the door axis.

[0042] When in use, when the box door 104 is closed, the door closing trigger shields the door closing proximity switch 1, and at this time, the box door of the box turning machine faces upwards. Figure 1 As shown. When there is a need for materials, the box flipper turns over so that the box door faces downward, and then the box door opens. During the process of the box door 104 being opened, the door closing trigger 4 moves away from the door closing proximity switch 1 as the box door 104 rotates, and the door opening trigger gradually approaches the door opening proximity switch 2. When the door opening trigger 9 blocks the door opening proximity switch 2, the box door stops moving. During this process, the material falls from the box flipper. After completing the unloading task, the box door 104 is closed. During the process of the box door 104 being closed, the door closing trigger 4 gradually moves toward the door closing proximity switch 1 as the box door 104 rotates, and the door opening trigger gradually moves away from the door opening proximity switch 2. When the door closing trigger 4 blocks the door closing proximity switch 1, the box door reaches a closed state.

[0043] The door opening trigger and door closing trigger settings of the present application can prevent debris and other factors from affecting the door opening and closing detection, solve the problem of high failure rate of door opening and closing detection of the carton tipper, improve the stability and reliability of the carton tipper operation, and solve the problem of the door opening and closing angle not being adjustable, and can achieve stable detection of the door opening and closing of the carton tipper under complex working conditions.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
