[0039] Palletizers are mainly used to stack products in a certain arrangement to reduce labor and labor intensity. In some technologies, palletizers use clamping devices to clamp and carry products. When clamping products of different sizes, different clamping spaces need to be set. However, due to factors such as the size accuracy of the clamped products themselves and the movement accuracy of the palletizer, there are problems in the clamping process where products are not clamped tightly and fall off, or products are clamped too tightly and cause indentations.
[0040] Based on the above problems, the utility model proposes a clamping device that can be used in a palletizer, which can reduce the risk of product falling and the risk of product crushing. Figure 1 Figure 1 This is a schematic structural diagram of a first clamping device according to an embodiment of the first aspect of the utility model. The clamping device of this embodiment includes: a first clamping member 100, a second clamping member 200, a connecting member 300, a driving mechanism and a detection mechanism 500.
[0041] The second clamping member 200 and the first clamping member 100 are distributed along the first direction. The first direction is, for example, a vertical direction, but not limited thereto. It can also be a horizontal direction according to requirements. The first clamping member 100 and the second clamping member 200 are, for example, flat plate structures to increase the contact area between the first clamping member 100 and the second clamping member 200 and the product, thereby reducing the risk of the product being crushed. The connecting member 300 is connected to the first clamping member 100 and can move relative to the first clamping member 100 along the first direction. One end of the elastic member 400 is connected to the first clamping member 100, and the other end is connected to the connecting member 300, and is used to apply a force toward the second clamping member 200 to the first clamping member 100. The elastic member 400 is, for example, any elastic structural member such as a compression spring, a tension spring or a spring sheet, as long as it can apply a force toward the second clamping member 200 to the first clamping member 100 through elastic deformation. The driving mechanism is, for example, a cylinder, a hydraulic cylinder or a motor, and the driving mechanism is connected to the connecting member 300, and is used to drive the connecting member 300 to reciprocate in the first direction. For example, the driving mechanism includes a driving motor, a screw and a nut, the screw is arranged along the first direction, the connecting member 300 is connected to the nut, and the driving motor is connected to the screw through a transmission mechanism such as a belt, a coupling or a gear, and is used to drive the screw to rotate, so that the nut moves along the first direction and drives the connecting member 300 to move. The detection mechanism 500 includes a sensor 510 and a sensing member 520, and the sensor 510 is, for example, a mechanical limit sensor 510, a magnetic limit sensor 510 or a photoelectric sensor 510, etc. One of the sensor 510 and the sensing member 520 is connected to the connecting member 300, and the other is connected to the first clamping member 100. The detection mechanism 500 is configured such that: the sensor 510 moves to the position of the sensing member 520, and the sensor 510 detects a change in the signal to stop the driving mechanism.
[0042] Specifically, the driving mechanism is connected to the connecting member 300, the elastic member 400 is arranged between the connecting member 300 and the first clamping member 100, one of the sensor 510 and the inductive member 520 is connected to the connecting member 300, and the other is connected to the first clamping member 100. When the clamping device of this embodiment is used in a palletizer, during the palletizing process, the driving mechanism drives the first clamping member 100 to move toward the second clamping member 200 to clamp the product. When the first clamping member 100 contacts the product, the first clamping member 100 stops moving, and due to the deformation ability of the elastic member 400, the connecting member 300 will further move a distance toward the second clamping member 200 until the sensor 510 detects the inductive member 520, and the detection signal of the sensor 510 changes to stop the driving mechanism and stop the connecting member 300 from moving too much, thereby avoiding excessive pressure on the product due to excessive movement of the connecting member 300, thereby reducing the risk of product crushing. At the same time, the elastic member 400 is in a deformed state and continuously applies a thrust toward the second clamping member 200 to the first clamping member 100 , so that the first clamping member 100 continuously applies pressure toward the product to reduce the risk of the product falling.
[0043] It should be noted that the program used between the above-mentioned sensor 510 and the driving mechanism is a common feedback program in the production process, which can be easily obtained by those skilled in the art.
[0044] Reference Figure 1 Based on the above embodiment, the first direction is a vertical direction, the second clamping member 200 is arranged below the first clamping member 100, the clamping device further includes a clamping seat 600, the second clamping member 200 is fixed to the clamping seat 600, the clamping device includes a guide assembly 700, the guide assembly 700 includes a first guide structure 710, the first guide structure 710 is connected to the clamping seat 600, the second guide structure 720 is connected to the first clamping member 100, and the first guide structure 710 and the second guide structure 720 are slidably matched along the first direction. The first guide structure 710 and the second guide structure 720 are, for example, configured as a slide rail and a slider, a guide rod and a guide cylinder to improve the stability of the first clamping member 100. And when the second clamping member 200 is located below the first clamping member 100, during the clamping process, the second clamping member 200 is first extended to the bottom of the product, and the product is clamped by driving the first clamping member 100, so that when the product is not clamped, the product will not move upward, thereby improving the stability of the product during the clamping process. Specifically, if the second clamping member 200 is slidably connected to the clamping seat 600 and driven by a driving mechanism, during the clamping process, if the product has not been clamped by the first clamping member 100 and the second clamping member 200, the product will move upward with the second clamping member 200, and since the product is not clamped, the risk of the product falling will increase, and this embodiment can effectively improve this problem.
[0045] Reference Figure 2 and Figure 3 , Figure 2 for Figure 1 A schematic diagram of the structure of the first clamping member, Figure 3 for Figure 1 Schematic diagram of the structure of the first clamping member, the connecting member and the elastic member, in some embodiments, the first clamping member 100 has a clamping portion 110 and a connecting portion 120, the clamping portion 110 is used to clamp the product, the connecting portion 120 is connected to the clamping portion 110, the connecting portion 120 and the clamping portion 110 can be an integrated structure or a split structure, and the connecting portion 120 has a mounting hole 121 (refer to Figure 2 ), the connector 300 is inserted into the mounting hole 121 (refer to Figure 3 ), in the first direction, the mounting hole 121 has a first inner wall 1211 facing the second clamping member 200. Exemplarily, the mounting hole 121 extends along the second direction, and the mounting hole 121 is, for example, a blind hole or a through hole, and the mounting hole 121 can be a circular hole or a square hole, and in the first direction, the size of the connecting member 300 is smaller than the size of the mounting hole 121, so that the connecting member 300 can move in the mounting hole 121 along the first direction. When the connecting member 300 is driven by the driving mechanism to move away from the second clamping member 200, the connecting member 300 can abut against the first inner wall 1211 and drive the first clamping member 100 to move away from the second clamping member 200 to release the clamped product. It can be understood that the first clamping member 100 is driven to move away from the second clamping member 200 by the abutment between the connecting member 300 and the first inner wall 1211. At this time, the movement of the connecting member 300 does not need to be transmitted to the first clamping member 100 through the elastic member 400. Therefore, in the process of the first clamping member 100 moving away from the second clamping member 200, the elastic member 400 does not need to resist the gravity of the first clamping member 100, thereby improving the service life of the first elastic member 400. In addition, when the clamping device does not clamp the product, the elastic member 400 does not need to resist the gravity of the first clamping member 100, thereby avoiding continuous external force when the clamping device is not working, further extending the service life of the elastic member 400.
[0046] Reference Figure 3 and Figure 4 , Figure 4 for Figure 1Schematic diagram of the structure of the first clamping member, the elastic member and the guide member in the embodiment Based on the above embodiment, the connecting member 300 has a guide hole penetrating along the first direction, and the guide member 800 can be slidably inserted into the guide hole. The clamping device also includes a guide member 800, which is connected to the inner wall of the mounting hole 121 and extends along the first direction. Exemplarily, both ends of the guide member 800 are connected to the first clamping member 100 by welding, threaded connection or clamping. Taking threaded connection as an example, in the first direction, one of the two inner walls of the mounting hole 121 facing each other is provided with a threaded hole extending along the first direction, and the other is provided with a through hole extending along the first direction and connected to the mounting hole 121. When installing, the guide member 800 is extended from the through hole into the mounting hole 121 and connected to the inner wall of the mounting hole 121 through the threaded hole. The connecting member 300 is sleeved on the outside of the guide member 800, thereby improving the stability of the connecting member 300 moving relative to the first clamping member 100. The guide member 800 is, for example, a cylinder, a triangular prism or a quadrangular prism, and correspondingly, the guide hole is set to a circular hole, a triangular hole or a square hole. As long as the guide member 800 can be slidably matched with the guide hole, the stability of the connecting member 300 relative to the first clamping member 100 can be improved.
[0047] Reference Figure 4 Based on the above embodiments, in some embodiments, the elastic member 400 is sleeved on the outside of the guide member 800, one end of the elastic member 400 is abutted against the connecting member 300, and the other end is abutted against the first clamping member 100, without the need to connect the elastic member 400 through other structures, thereby making the clamping device structure of this embodiment simpler and reducing the assembly cost and manufacturing cost of the clamping device.
[0048] Reference Figure 2In some embodiments, the connecting portion 120 includes a main body 122 and a first connecting portion 123. The main body 122 has a first groove 1221. The first groove 1221 has a first opening facing away from the second clamping member 200. The first connecting portion 123 is connected to the main body 122 and covers the first opening to form the mounting hole 121 in the above embodiment. The inner wall of the first groove 1221 has a first connecting hole 1222 facing the first connecting portion 123. The first connecting portion 123 has a second connecting hole facing the main body 122. The two ends of the guide member 800 are respectively inserted into the first connecting hole 1222 and the second connecting hole. Therefore, during installation, it is only necessary to insert the two ends of the guide member 800 into the first connecting hole 1222 and the second connecting hole, and the first connecting portion 123 is connected to the main body 122, so that the installation of the guide member 800 is simpler. Furthermore, in some embodiments, the first connecting portion 123 and the main body portion 122 are detachably connected by screws or bolts. When the clamping device is used for a long time and causes the guide member 800 or the connecting member 300 to wear, or the elastic member 400 is subjected to force for a long time and its elastic energy decreases, the guide member 800, the connecting member 300 or the elastic member 400 can be removed and replaced separately without replacing the entire clamping device, thereby saving maintenance costs.
[0049] Reference Figure 2 and Figure 5 , Figure 5 for Figure 4 , based on the above embodiment, the first connection part 123 has a protrusion 1231 protruding away from the main body 122, the first connection part 123 has a third groove 1232 facing the clamping part 110, the third groove 1232 extends to the protrusion 1231, and the inner wall of the first groove 1221 and the third groove 1232 defines the mounting hole 121. Specifically, the first connection part 123 is partially protruding, and the third groove 1232 is formed on the first connection part 123 by processing, therefore, under the premise that the size of the mounting hole 121 along the first direction is constant, the size of the first groove 1221 can be reduced, thereby improving the strength of the main body 122, and further improving the service life of the clamping device of this embodiment.
[0050] Reference Figure 2 and Figure 5In some embodiments, the main body 122 includes a second connection portion 1223 and a third connection portion 1224, the third connection portion 1224 has a second groove 12241 facing the first connection portion 123, the second connection portion 1223 is arranged in the second groove 12241 by welding, screw connection or clamping, and the surface of the second connection portion 1223 facing the first connection portion 123 and the inner wall of the second groove 12241 define the first groove 1221, and the second connection portion 1223 has a first connection hole 1222. Specifically, it can be understood that the guide member 800 is plugged into the second connection portion 1223, so the size of the second connection portion 1223 in the second direction (perpendicular to the first direction) needs to be larger than the size of the guide member 800. In the present embodiment, the second connection part 1223 and the main body part 122 are split structures. Therefore, the second connection part 1223 and the third connection part 1224 can be formed by processing raw materials of different sizes. It is only necessary to make the size of the second connection part 1223 larger than the size of the guide member 800, and there is no need for the overall size of the main body part 122 to be larger than the size of the guide member 800. This not only saves the manufacturing cost of the first clamping member 100, but also reduces the mass of the first clamping member 100, thereby reducing the energy consumption of the driving mechanism when it is working, thereby saving the use cost.
[0051] Reference Figure 2 and Figure 6 , Figure 6 for Figure 2 Enlarged view of the middle A area, in some embodiments, the first connection hole 1222 is set as a blind hole on the second connection part 1223, the second connection part 1223 has a slot 12231 opposite to the first connection hole, and the third connection part 1224 is snapped into the slot 12231, so that the connection of the second connection part 1223 is simpler and the assembly cost is reduced. Specifically, the first connection hole 1222 is a blind hole, so that in the first direction, the second connection part 1223 can be clamped by the guide member 800 and the third connection part 1224, and at the same time, the second connection part 1223 can be prevented from being separated from the second groove 12241 by the setting of the slot 12231, so that the second connection part 1223 is firmly restricted in the second groove 12241, and it is not necessary to connect with the third connection part 1224 by screw connection or welding, thereby saving assembly steps. At the same time, it is not necessary to form a through hole for screw connection on the second connection part 1223, so that the structure of the second connection part 1223 is more compact.
[0052] Reference Figure 1In some embodiments, the clamping device further includes an anti-slip member 900, and at least one of the two surfaces of the first clamping member 100 and the second clamping member 200 facing each other is provided with an anti-slip member 900. The anti-slip member 900 is made of, for example, rubber, silicone, or nylon. For example, the surface of the first clamping member 100 facing the second clamping member 200 is connected with the anti-slip member 900, thereby increasing the friction between the clamping device and the product, thereby increasing the stability of the product when being clamped, and reducing the risk of the product falling. Similarly, in some embodiments, the surface of the second clamping member 200 facing the first clamping member 100 is connected with a protective anti-slip member 900, or the two surfaces of the first clamping member 100 and the second clamping member 200 facing each other are connected with anti-slip members 900.
[0053] The palletizer of the second embodiment of the utility model comprises the clamping device of the first embodiment, wherein the driving mechanism in the clamping device is connected to the connecting member 300, the elastic member 400 is arranged between the connecting member 300 and the first clamping member 100, and one of the sensor 510 and the inductive member 520 is connected to the connecting member 300, and the other is connected to the first clamping member 100. During the palletizing process, the driving mechanism drives the first clamping member 100 to move toward the second clamping member 200 to clamp the product, and when the first clamping member 100 contacts the product, the first clamping member 100 stops moving, and due to the deformation ability of the elastic member 400, the connecting member 300 will further move a distance toward the second clamping member 200 until the sensor 510 detects the inductive member 520, and the detection signal of the sensor 510 changes to stop the driving mechanism and stop the connecting member 300 from moving, thereby avoiding excessive pressure on the product due to excessive movement of the connecting member 300, thereby reducing the risk of product damage. At the same time, the elastic member 400 is in a deformed state and continuously applies a thrust toward the second clamping member 200 to the first clamping member 100 , so that the first clamping member 100 continuously applies pressure toward the product to reduce the risk of the product falling.
