Description

Technical Field

[0001] This invention belongs to the field of tobacco machinery, specifically relating to a tobacco box clamping device and method. Background Technology

[0002] The existing mobile clamping machine used in tobacco processing workshops clamps the tobacco boxes by using a cylinder-driven clamping plate to apply pressure and tighten it. The box is then lifted, conveyed to a conveyor roller, and finally released, allowing it to be transported to the production line. However, this method has the following problems in actual production: 1. For saturated tobacco boxes, the clamping pressure needs to be high, which can easily deform the boxes and materials during the clamping process. 2. For unsaturated tobacco boxes, the friction between the clamping plate and the box surface is insufficient to ensure stability, leading to the boxes falling downwards. Increasing the pressure can easily deform the boxes during clamping. In both cases, controlling the clamping pressure is difficult, and deformation of the boxes and even the materials themselves frequently occurs. This not only affects production efficiency but also product quality.

[0003] This invention is proposed for this purpose. Summary of the Invention

[0004] The purpose of this invention is to provide a cigarette box clamping device and a method for clamping cigarette boxes using the cigarette box clamping device. In addition to the horizontal clamping force of the two clamping plates, this invention provides an outward suction force by adding retractable suction cups to the inner side of the two clamping plates to adhere to the surface of the cigarette box, increasing friction and preventing deformation of the cigarette box; thus fundamentally eliminating the problem of the cigarette box being squeezed and deformed, or even the material being squeezed and deformed, during the clamping and handling process.

[0005] The technical solution of the present invention is as follows:

[0006] The first aspect of the present invention discloses a cigarette box clamping device, the device comprising two symmetrically arranged clamping plates, each clamping plate having a plurality of suction cup holes 1 evenly distributed on its surface, each suction cup hole containing a suction cup X, the opening of the suction cup X facing the inside of the clamping plate.

[0007] Preferably, on the clamping plate surface, each of the four vertices of the rectangle outside each suction cup hole 1 is provided with a plate fixing hole 11; on the outer side of the clamping plate, each plate fixing hole 11 is fixedly connected to a connecting rod 12; the other ends of the four connecting rods 12 are fixedly connected to the four seat fixing holes 21 of the cylinder seat 2; a cylinder 3 is installed on the cylinder seat 2 through the cylinder fixing hole 23.

[0008] Preferably, the device further includes a rectangular slide 4; the slide 4 has four holes at its four corners, which are slide holes 41, and the inner diameter of the slide holes 41 is adapted to the outer diameter of the connecting rod 12.

[0009] Preferably, the bottom of the suction cup X is connected to a suction cup fixing rod 43, which is fixed in the rod hole 42 in the center of the slide block 4 and connected to the piston of the cylinder 3 through the seat hole 22.

[0010] Preferably, each suction cup X has an air tube at its bottom that is connected to a vacuum device.

[0011] Preferably, a distance sensor 5 is provided at the relative position of the inner sides of the two clamping plates.

[0012] A second aspect of this invention discloses a method for clamping a cigarette box, using the aforementioned cigarette box clamping device, comprising the following steps:

[0013] When the cigarette box clamping device needs to clamp the cigarette box, the two clamping plates close together horizontally. When the distance between the two clamping plates is detected by the distance sensor 5 as being close to the length of the cigarette box, some or all of the cylinders 3 act synchronously, pushing their respective slides 4 forward, thereby pushing the suction cups X out of the inner side of the clamping plates; the vacuum device is activated, and some or all of the suction cups X adhere to the surface of the cigarette box; at this time, the cigarette box clamping device picks up the cigarette box and can place the cigarette box in the target position.

[0014] At this time, the vacuum device stops working, and some or all of the suction cups X are released from the surface of the smoke box; and some or all of the cylinders 3 move synchronously, driving their respective slides 4 to move backward and return to their respective suction cup holes 1; at the same time, the two clamping plates move away from each other in the horizontal direction; ready to perform the next smoke box clamping action.

[0015] The beneficial effects of this invention are:

[0016] The cigarette box clamping device of the present invention provides an outward adsorption force by setting multiple suction cups X on the two clamping plates to adsorb the surface of the cigarette box. Combined with the horizontal clamping force of the two clamping plates, the friction between the clamping plates and the surface of the cigarette box is increased, which completely solves the problem of cigarette boxes (whether empty or full of cigarettes) being squeezed and deformed or even the material being squeezed and deformed during the clamping and handling process in the prior art.

[0017] The cigarette box clamping device of the present invention features a retractable suction cup X, the height of which protrudes from the inner side of the clamping plate can be controlled, such as 5mm-20mm. Furthermore, the suction cup X can be partially or fully activated as needed, preventing deformation when subjected to vertical forces and allowing it to withstand larger loads. This significantly improves operational efficiency. Attached Figure Description

[0028] like Figure 1-4 As shown, a cigarette box clamping device of the present invention includes two symmetrically arranged clamping plates. Each clamping plate has a plurality of suction cup holes 1 evenly distributed on its surface. Each suction cup hole contains a suction cup X, and the opening of the suction cup X faces the inside of the clamping plate.

[0029] Among them, on the clamping plate surface, each of the four vertices of the rectangle outside each suction cup hole 1 is provided with a plate fixing hole 11; on the outer side of the clamping plate, each plate fixing hole 11 is fixedly connected to a connecting rod 12; the other ends of the four connecting rods 12 are fixedly connected to the four seat fixing holes 21 of the cylinder seat 2; the cylinder 3 is installed on the cylinder seat 2 through the cylinder fixing hole 23.

[0030] The device also includes a rectangular slide block 4; the slide block 4 has four holes at its four corners, which are slide block holes 41. The inner diameter of the slide block holes 41 is adapted to the outer diameter of the connecting rod 12, that is, the slide block holes 41 can slide along the connecting rod 12 through the slide block holes 41.

[0031] The suction cup X has a suction cup fixing rod 43 connected to its bottom. The suction cup fixing rod 43 is fixed in the rod hole 42 in the center of the slide block 4 and is connected to the piston of the cylinder 3 through the seat hole 22.

[0032] Each suction cup X has an air tube connected to a vacuum device at its bottom to ensure a vacuum inside the suction cup X for adsorption onto the surface of the smoke box; the air tube and vacuum device are not shown in the figure.

[0033] Among them, there is a distance sensor 5 at the relative position of the inner sides of the two clamping plates, which is used to sense the distance between the two clamping plates.

[0034] The process of clamping a cigarette box using the cigarette box clamping device of the present invention includes the following steps:

[0035] When the cigarette box clamping device needs to clamp the cigarette box, the two clamping plates close together horizontally. When the distance between the two clamping plates is detected by the distance sensor 5 as being close to the length of the cigarette box, some or all of the cylinders 3 act synchronously, pushing their respective slides 4 forward, thereby pushing the suction cups X out of the inner side of the clamping plates; the vacuum device is activated, and some or all of the suction cups X adhere to the surface of the cigarette box; at this time, the cigarette box clamping device picks up the cigarette box and can place the cigarette box in the target position.

[0036] At this time, the vacuum device stops working, and some or all of the suction cups X are released from the surface of the smoke box; and some or all of the cylinders 3 move synchronously, driving their respective slides 4 to move backward and return to their respective suction cup holes 1; at the same time, the two clamping plates move away from each other in the horizontal direction; ready to perform the next smoke box clamping action.

[0037] The cigarette box clamping device of this invention utilizes multiple suction cups X on the two clamping plates to provide an outward adsorption force to the cigarette box surface. Combined with the horizontal clamping force of the two clamping plates, this increases the friction between the clamping plates and the cigarette box surface, completely solving the problem of cigarette boxes (whether empty or full of cigarette packs) being squeezed and deformed, or even the material itself being squeezed and deformed, during the clamping and handling process in existing technologies. The suction cups X in this invention are retractable, and the height of the suction cups protruding from the inner side of the clamping plates can be controlled, such as 5mm-20mm. Furthermore, the suction cups X can be partially or fully activated as needed, preventing deformation when subjected to vertical forces and allowing them to withstand larger loads. This significantly improves operational efficiency.

[0038] The above embodiments are not intended to limit the present invention, nor is the present invention limited to the examples described above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
