At present, a carton stacker has been developed to assist operators in stacking. The carton stacker automatically stacks the packed cartons. After stacking to multiple layers, it is pushed out and transported to the warehouse for storage by forklift. At present, a grating sensor is used to detect the position of the stacked cartons. For example, Chinese patent announcement number CN217147815U discloses a carton stacking device. The specific scheme is: the cache mechanism includes a rectangular bracket, a bottom plate is fixed on the upper part of the rectangular bracket, and a fixed baffle and an adjustable baffle are installed on opposite sides above the bottom plate. A pair of slide rails are installed between the fixed baffle and the adjustable baffle, and the adjustable baffle can be moved on the slide rail. A grating sensor is installed on the adjustable baffle, wherein the grating sensor has the purpose of detecting the position of the box.

[0003] However, in practical applications and in the appendix to the above patent documents Figure 4 It is known that grating sensors are usually in the shape of long strips, which have the disadvantages of bulky structure and high cost. When used in palletizers, they will take up too much space and increase the price of the whole machine, which is not conducive to application and promotion. Based on this, it is necessary for this application to disclose a palletizer cargo height detection device to overcome the above-mentioned disadvantages. Utility Model Content

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] like Figures 1 to 6 As shown, a palletizer cargo stack height detection device comprises a palletizer 1, wherein the palletizer 1 has a palletizing station, and one of the diagonals of the palletizing station is provided with a beam sensing component 2 (that is, two beam sensing components 2 are installed); specifically, the palletizer 1 comprises a palletizer frame 101, and the beam sensing component 2 is fixed on the palletizer frame 101; the beam sensing component 2 comprises a mounting plate 201 and an infrared sensor 202, wherein the mounting plate 201 is fixed on the palletizer frame 101, and the infrared sensor 202 is fixed on the mounting plate 201; therefore, in the present application, mainly by providing an infrared sensor 202 on the diagonal of the palletizing station, the height of the stacked cartons at the palletizing station can be detected, which solves the defects of the traditional need to install a grating sensor, which has high cost and bulky structure.

[0030] Specifically, the mounting plate 201 includes a first plate 2011 and a second plate 2012 which are perpendicular to each other. The first plate 2011 and the second plate 2012 are welded and fixed or formed by bending after being integrally formed as in the present embodiment. The infrared sensor 202 is fixed on the first plate 2011, and the second plate 2012 is fixedly connected to the palletizing machine frame 101. The connection structure between the infrared sensor 202 and the second plate 2012 is: the infrared sensor 202 is provided with a third connecting hole, which is an internal threaded hole. A longitudinal groove 20121 is longitudinally opened on the second plate 2012. The screw passes through the longitudinal groove 20121 and is connected to the third connecting hole and tightened, thereby locking the infrared sensor 202 on the second plate 2012. The longitudinal groove 20121 is designed to adjust the fixing height of the infrared sensor 202 on the second plate 2012.

[0031] The second plate 2012 is provided with an opening 20111 and a slot 20112; the palletizing frame 101 is provided with a first connecting hole 1011 and a second connecting hole 1012 corresponding to the opening 20111 and the slot 20112 respectively; the first connecting hole 1011 and the second connecting hole 1012 are also internal threaded holes, and further include a first bolt 3 and a second bolt 4, the first bolt 3 passes through the opening 20111 and is connected to the first connecting hole 1011, and the second bolt 4 passes through the slot 20112 and is connected to the second connecting hole 1012, so that the first plate 2011 is fixed to the palletizing frame 101, by Figures 2 to 5 It can be seen that the slot 20112 is an arc shaped with the first connecting hole 1011 as the center and the straight distance between the first connecting hole 1011 and the second connecting hole 1012 as the radius. The slot 20112 is to facilitate the plane rotation of the first plate 2011 (that is, the plane rotation of the radiation sensing component 2), and to facilitate the adjustment of the two infrared sensors 202 on the diagonal line for radiation sensing. When adjusting, loosen the first bolt 3 and the second bolt 4, rotate the first plate 2011 with the first bolt 3 as the center to adjust the angle, and then tighten the first bolt 3 and the second bolt 4.

[0032] The first plate 2011 and the second plate 2012 form an operation area 2013, and the first bolt 3, the second bolt 4, and the infrared sensor 202 are all located in the operation area 2013. The operation area 2013 refers to the area formed by the first plate 2011 and the second plate 2012, which is open and has no shielding, which is conducive to the tightening operation of the first bolt 3 and the second bolt 4 and the installation of the infrared sensor 202.

[0033] The first bolt 3 and the second bolt 4 are both sleeved with a flat washer 5, and a spring washer 6 is arranged above the flat washer 5. The flat washer 5 can disperse the pressure and disperse the tightening pressure of the first bolt 3 and the second bolt 4 directly on the first plate 2011; the spring washer 6 can prevent loosening and increase the pre-tightening force to make up for the defects of the flat washer 5.

[0034] The lower surface of the second plate 2012 is flat, and the mounting surface of the palletizer rack 101 is also flat, which helps to enhance the installation and fixing effect of the second plate 2012 on the palletizer rack 101; and the corners between the first plate 2011 and the second plate 2012 are rounded, which also avoids the corners being too sharp and causing harm to the operator during installation and disassembly.

[0035] The palletizing machine frame 101 is connected with a semi-enclosed protective cover 7. Figure 6 It can be seen that the semi-enclosed protective cover 7 has a top cover and a side cover. When the semi-enclosed protective cover 7 is installed on the palletizer frame 101, the opening formed by the top cover and the side cover is facing inward, and the semi-enclosed protective cover 7 covers the opposite-radiation sensing component 2 without blocking the opposite-radiation sensing component 2, thereby achieving the dust-proof and protective effects.

[0036] The semi-enclosed protective cover 7 is detachably connected to the palletizer frame 101 by means of screw connection, and since the mounting plate 201 is also detachably connected to the palletizer frame 101 by means of the first bolt 3 and the second bolt 4, it is convenient for assembly and disassembly and is also beneficial for later maintenance.

[0037] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
