Abstract

The pallet separation device provided by the present invention is provided with a separation mechanism located on the left and right sides of the pallet, and the separation mechanism includes a bottom plate, a separation plate slidably arranged on the bottom plate and a cylinder for driving the separation plate to slide. When the separation plate slides left and right relative to the bottom plate, a part of the separation plate extends into the gap between the two stacked pallets, so that when the upper pallet moves upward, the technical effect of blocking the lower pallet from following the movement is achieved. By providing a guide slope that is at an acute angle to the sliding direction of the separation plate on the separation plate, and providing a connecting block on the cylinder rod, the end of the connecting block away from the cylinder rod is in contact with the guiding slope. When the cylinder rod is extended and retracted in the front-rear direction, the contact between the connecting block and the guiding slope can drive the separation plate to slide left and right, so that the pallet separation device provided by the present invention has a compact structure and occupies a small area, and is suitable for promotion and use in automated production lines.

Description

Technical Field

[0001] The invention relates to the field of tray separation, and in particular to a tray separation device. Background Art

[0002] Pallets are essential load-bearing components in industrial production. They are used to support products. By moving the pallets, products can be moved to a specific location without contacting the products. Pallets are widely used in the manufacturing or packaging process of products.

[0003] In order to reduce the floor space and increase the number of pallets that can be stored, pallets are generally stacked in an overlapping manner. When they are taken out, the two stacked pallets are prone to adhesion. When the upper pallet moves upward, the lower pallet will follow and move upward, which is very inconvenient. Especially in the automated production line of the product, the sticky pallets will cause the production line to malfunction, and in severe cases, it will cause damage to the production line. There are also separation devices for separating pallets on the market, but most of them have complex structures and occupy a large area. When using this separation device, the distance between two adjacent stacked pallets is large, resulting in serious waste of space. Summary of the invention

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] The left and right directions described in the present invention refer to Figure 1 The left and right directions in the present invention refer to the front and rear directions. Figure 1 The downward and upward directions in the .

[0031] Embodiment 1

[0032] like Figure 1-3As shown, the present invention provides a tray separation device, including a separation mechanism 100, the separation mechanism 100 is arranged in pairs, in this embodiment, the separation mechanism 100 is arranged on the left and right sides of the tray 600, the separation mechanism 100 on the left and right sides of the tray 600 has the same structure, and the separation mechanism 100 located on the right side of the tray 600 is described below, the separation mechanism 100 includes a bottom plate 200, a separation plate 300, a cylinder 400 and a connecting block 500, wherein the separation plate 300 is slidably arranged on the upper surface of the bottom plate 200, specifically, the upper surface of the bottom plate 200 A slide rail 201 extending in the left-right direction is provided, and a slider 301 matching the slide rail 201 is provided on the lower surface of the separation plate 300. The slider 301 can be slidably mounted on the slide rail 201, so that the separation plate 300 can slide in the left-right direction relative to the bottom plate 200. When the tray separation device separates the tray 600, a part of the separation plate 300 can extend into the gap between the two stacked trays, and when the upper tray moves upward, the lower tray is blocked from following the movement, thereby achieving the technical effect of separating the trays; the cylinder 400 is used to drive the separation plate 300. The cylinder 400 slides left and right relative to the bottom plate 200, and a connecting block 500 is arranged on the upper surface of the bottom plate 200. The cylinder rod 401 of the cylinder 400 is provided with a connecting block 500; the separation plate 300 is also provided with a guide inclined surface 3021, and the angle between the guide inclined surface 3021 and the sliding direction of the separation plate 300 is an acute angle. Specifically, a guide groove 302 is opened on the upper surface of the separation plate 300 and runs through the upper and lower surfaces of the separation plate 300. The angle between the extension direction of the guide groove 302 and the sliding direction of the separation plate 300 is an acute angle. The guide groove 302 is parallel to the guide groove 302. The side wall in the extension direction forms a guiding slope 3021; ​​a connecting column 501 is provided at the end of the connecting block 500 away from the cylinder rod 401, and the cross-section of the connecting column 501 is circular. The connecting column 501 extends into the guide groove 302, and the outer circumferential surface of the connecting column 501 contacts the guiding slope 3021. The cylinder rod 401 extends and retracts along the front-to-back direction. When the cylinder rod 401 extends and retracts, the cylinder rod 401 drives the connecting block 500 to move forward and backward, and drives the separation plate 300 to slide left and right relative to the bottom plate 200 through the guiding slope 3021 in contact with the end of the connecting block 500.

[0033] The angle between the guide slope 3021 and the sliding direction of the separation plate 300 will affect the sliding distance of the separation plate 300 when the cylinder rod 401 is extended or retracted, and at the same time affect the load when the cylinder rod 401 is extended or retracted. When the angle becomes larger, the distance that the cylinder rod 401 extends or retracts the separation plate 300 to slide becomes smaller, and it is difficult to accurately control the sliding distance of the separation plate 300, but the load when the cylinder rod 401 is extended or retracted will be reduced; when the angle becomes smaller, the distance that the cylinder rod 401 extends or retracts the separation plate 300 to slide becomes larger, and the sliding distance of the separation plate 300 can be accurately controlled, but the load when the cylinder rod 401 is extended or retracted will be larger; preferably, the angle range of the angle is 20°-70°. In the present embodiment, the angle is 65°.

[0034] The end of the connecting block 500 away from the cylinder rod 401 also has a first branch plate 504 and a second branch plate 505, wherein the first branch plate 504 is located above the separation plate 300, the upper end of the connecting column 501 is connected to the first branch plate 504, the second branch plate 505 is located below the separation plate 300, and the lower end of the connecting column 501 is connected to the second branch plate 505. The advantage of such an arrangement is that both ends of the connecting column 501 are connected to the connecting block 500, which can significantly improve the stability and service life of the connecting column 501 during use compared to the connecting column 501 with one end connected to the connecting block 500.

[0035] The separation plate 300 is provided with a claw portion 305 extending toward the direction close to the tray 600 and protruding from the side wall of the separation plate 300. When the tray separation device separates the tray, as shown in FIG. Figure 2 As shown, the claw portion 305 extends into the gap between two stacked trays.

[0036] Embodiment 2

[0037] like Figure 4-6As shown, the second embodiment is substantially the same as the first embodiment, except that there are two guide grooves in the second embodiment, namely the first guide groove 303 and the second guide groove 304, the two guide grooves are arranged in parallel and spaced apart, the first guide groove 303 forms a first guide slope 3031 and a second guide slope 3032 on the side wall along the extension direction of the first guide groove 303, and the second guide groove 304 forms a third guide slope 3041 and a fourth guide slope 3042 on the side wall along the extension direction of the second guide groove 304; there are also two connecting columns, namely the first connecting column 502 and the second connecting column 503, the first connecting column 502 is sleeved with a first bearing 5021, the second connecting column 503 is sleeved with a second bearing 5031, the first bearing 5021 is located in the first guide groove 303, the second bearing 5031 is located in the second guide groove 304, the first bearing 5021 The outer circumferential surface of the second bearing 5031 contacts the third guide inclined surface 3041 in the second guide groove 304 close to the cylinder 400, and the advantage of such an arrangement is that, on the one hand, the sliding friction between the connecting column and the guiding inclined surface is changed into rolling friction, thereby reducing friction loss and increasing the service life of the connecting column; on the other hand, the gap between the separation plate 300 and the connecting column in the sliding direction is eliminated, thereby reducing the shaking of the separation plate 300 in the left and right directions when the cylinder rod 401 drives the separation plate 300 to slide to the end point, thereby ensuring that the separation plate 300 is in the same position relative to the bottom plate 200 at the sliding end point; it can be imagined that this technical effect can also be achieved by rotatably arranging the connecting column on the connecting block so that the outer wall of the connecting column contacts the guiding inclined surface.

[0038] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0039] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
