Description

Technical Field

[0001] The utility model relates to the field of palletizers, in particular to a clamping structure for mattress palletizing and a mattress palletizer. Background Art

[0002] With the development of technology, mattress palletizers are essential equipment in the mattress production process. The clamping structure of existing mattress palletizers usually clamps mattresses in two directions by rotating, and the existing clamping structure is usually bent. When unloading mattresses, it is necessary to first expand the clamping width in the horizontal direction to release the mattresses, thereby occupying the stacking space. Therefore, the clamping structure of the existing mattress palletizer cannot store mattresses tightly, and the existing clamping structure can only stack mattresses independently. However, the independently arranged mattress stacks require workers to perform secondary handling, so that the stacks are arranged tightly to reduce the occupation of storage space; but the secondary handling process requires more workers and machinery, consuming more labor costs.

DETAILED DESCRIPTION

[0027] In order to make the technical purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0029] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] The embodiment of the utility model provides a clamping structure for mattress stacking.

[0031] See also Figure 1 , In one embodiment, the mattress stacking clamping structure includes a clamping assembly;

[0032] The clamping assembly comprises: a mounting plate, a first guide rail, two symmetrically arranged first clamping plates, a first driving member, a first suction cup, a second driving member, a second guide rail, two symmetrically arranged second clamping plates and a fourth driving member;

[0033] The first guide rail, the first driving member, the second driving member and the second guide rail are all fixed to the mounting plate; the first clamping plate is slidably connected to the first guide rail; the first driving member is used to drive the two first clamping plates to move closer to or away from each other; the second guide rail is vertically arranged relative to the first guide rail; the second clamping plate is slidably connected to the second guide rail; the fourth driving member is fixed to the second guide rail, and is used to drive the two second clamping plates to move closer to or away from each other; the second driving member is used to drive the first suction cup to move towards or away from the clamped object; the first suction cup is located between the two first clamping plates and can absorb the clamped object.

[0034] It can be understood that the technical solution of the utility model is to set the first clamping plate 133, the second clamping plate 138 and the first suction cup 135 on the robot arm 120. The first clamping plate 133 and the second clamping plate 138 respectively assist in fixing the clamped objects in two directions. The first suction cup 135 is set to absorb the clamped objects and serve as the main force for the clamped objects to overcome gravity. When the clamping structure for mattress stacking releases the clamped objects, it only needs to release the adsorption force of the first suction cup 135 to easily stack the clamped objects, avoiding the occupation of the stacking area in the horizontal direction, so that the stacking is more compact, the space occupied by the stacking is reduced, and there is no need for secondary handling at the same time, which improves work efficiency and reduces labor costs.

[0035] It should also be noted that the first driving member 134, the second driving member 136, and the fourth driving member 139 can be electric push rods, hydraulic push rods, or pneumatic push rods, with the ability to achieve movement being the main focus, and there is no restriction on the specific types of the first driving member 134, the second driving member 136, and the fourth driving member 139.

[0036] The enclosed objects are not limited to mattresses or mattress packaging.

[0037] Specifically, the second driving member 136 is mainly provided to bring the first suction cup 135 close to the clamped object. The number of the first suction cup 135 can be multiple or single, and the suction cup is connected to an air source device capable of controlling the suction force.

[0038] It should also be noted that the second clamping plate 138 is provided to assist in fixing the clamped object, so as to prevent the clamped object from shaking during the moving process, thereby rendering the suction function of the first suction cup 135 ineffective, thereby reducing the occurrence of handling accidents.

[0039] Optionally, in another embodiment, the first suction cup 135 is also magnetic and can absorb objects containing iron, cobalt, and nickel.

[0040] In one embodiment, when releasing the clamped object, the first driving member 134, the second driving member 136, and the fourth driving member 139 only drive the first clamping plate 133, the first suction cup 135, and the first clamping plate 138 to move slightly. Before clamping the clamped object, the first driving member 134, the second driving member 136, and the fourth driving member 139 are in an initial state.

[0041] See also Figure 1 In a preferred embodiment, the mattress stacking clamping structure further includes a third driving member 140, which is disposed above the mounting plate 131 of the clamping assembly and connected to the mounting plate 131 to drive the mounting plate 131 to move. It can be understood that the third driving member 140 can be an electric push rod, a hydraulic push rod, or a pneumatic push rod, and the third driving member 140 is mainly used to drive the clamping assembly 130 to move quickly, so that the clamped object can be separated from the clamping assembly 130 under the action of inertia.

[0042] Furthermore, in a specific embodiment, the first driving member 134 is located on a side of the first clamping plate 133 away from the first suction cup 135 ; the second driving member 136 is located on a side of the second clamping plate 138 close to the first suction cup 135 .

[0043] It is understandable that the lengths of the first guide rail 132 and the second guide rail 137 are usually set to be similar in consideration of the rationality and aesthetics of the design. When the mattress stacking clamping structure is only used for clamping mattresses, the mattress is usually rectangular, and the first driving member 134 is arranged on the side of the first clamping plate 133 away from the first suction cup 135, and the second driving member 136 is arranged on the side of the second clamping plate 138 close to the first suction cup 135, the distance between the two first clamping plates 133 will be smaller than the distance between the two second clamping plates 138, thereby adapting to the length-width ratio of the mattress and reducing the space occupied by the second guide rail 137.

[0044] Please continue reading Figure 1 and Figure 2 In one embodiment, the first clamping plate 133 and / or the second clamping plate 138 are provided with ribs 130a on a side close to the suction cup.

[0045] It is understandable that the provision of the ribs 130 a can increase the friction between the clamped object and the first clamping plate 133 or the second clamping plate 138 , thereby enhancing the auxiliary clamping effect of the first clamping plate 133 or the second clamping plate 138 .

[0046] Specifically, in one embodiment, the rib 130a is a wedge-shaped piece that is small at the top and large at the bottom. It can be understood that the wedge-shaped piece that is small at the top and large at the bottom can reduce the wear of the clamped object when it is separated from the first clamping plate 133 or the second clamping plate 138. On the other hand, the provision of the wedge-shaped piece can overcome a part of the gravity brought by the clamped object, and improve the reliability of the clamping and fixing of the clamped object by the first clamping plate 133 or the second clamping plate 138.

[0047] like Figure 3 and Figure 4 As shown, the technical solution of the utility model further proposes a mattress palletizer 100 , which includes a first transport structure 120 and a clamping structure for mattress palletizing as described above, and the first transport structure 120 is fixedly connected to the mounting plate 131 .

[0048] Optionally, the first transport structure 120 is a gantry crane.

[0049] Alternatively, if Figure 3 As shown, the first handling structure is a four-axis robotic arm or a six-axis robotic arm.

[0050] In a specific embodiment, the mattress palletizer 100 further includes a second mobile chassis;

[0051] Optionally, the mobile chassis is a crawler-type mobile chassis.

[0052] See also Figure 4 In a specific embodiment, the mobile chassis includes a third guide rail 151 and a third driving member 140, and the third guide rail 151 is fixed to the ground; the third driving member 140 is a rail trolley 152, and the chassis is arranged above the rail trolley 152.

[0053] Furthermore, the third guide rail 151 includes a first guide portion 1511 , an arc-shaped guide portion 1512 , and a second guide portion 1513 that are sequentially connected; the first guide portion 1511 and the second guide portion 1513 are arranged at an angle.

[0054] It is understandable that this design enables the rail trolley 152 to move in different directions, which facilitates the switching of the mattress palletizer 100 on different production lines, and is conducive to adjusting the working scene at any time and improving working efficiency.

[0055] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
