Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to an automatic straightening device for cigarette flow of a cigarette conveying line. Background Art

[0002] In the production process of tobacco cigarette products, the cigarettes produced by the cigarette making machine are transported to the packaging machine through the cigarette conveyor line to realize the packaging of the cigarettes. Since the production speed of the cigarette making machine and the packaging machine cannot be completely synchronized, there will be a flow difference of the cigarette flow. In order to make up for the flow difference, a tray unloading machine will be set up on the cigarette conveyor line to add the pre-stored cigarettes to the cigarette conveyor line. When the equipment is operating normally, most of the qualified cigarettes produced by the cigarette making machine are transported to the packaging machine through the cigarette conveyor line, and a small number of cigarettes are added to the cigarette conveyor line cigarette flow through the tray unloading machine; when the cigarette making machine is stopped, the tray unloading machine alone completes the supply of cigarettes to the packaging machine.

[0003] During the unloading process of the tray unloader, the unloading conveyor belt of the tray unloader is tilted, and the cigarettes tend to slide outward, causing the cigarettes to be misaligned at the confluence of the tray unloader and the cigarette conveyor line. Misaligned cigarettes are easily blocked by shields during transportation, which can easily lead to horizontal cigarettes, cigarette extrusion and deformation, or conveyor line blockage, which in turn causes frequent shutdowns of the packaging machine's cigarette warehouse, resulting in reduced equipment efficiency and increased material consumption.

[0012] Furthermore, the cylinder is installed on a cylinder mounting box, and the cylinder mounting box is a semi-enclosed structure; the cylinder is fixedly connected to the cylinder mounting box.

[0013] Furthermore, a first long waist hole is opened on the bottom surface of the cylinder mounting box, and the cylinder mounting box is connected to the fixing seat bolts through the first waist hole, so that the horizontal position of the cigarette clapper can be adjusted.

[0014] Furthermore, a second long waist hole is opened in the vertical direction of the fixing seat, and the fixing seat is connected to the protective cover bolts through the second waist hole, so that the cigarette beater can be adjusted up and down.

[0015] Furthermore, two parallel baffles are arranged on the U-shaped mounting plate, and a certain interval is formed between the parallel baffles to form an accommodating cavity. The cylinder is arranged in the accommodating cavity and fixedly connected to the U-shaped mounting plate, which is convenient for positioning the cylinder during installation. At the same time, the cylinder can be limited to prevent horizontal movement of the cylinder from affecting the beating effect.

[0016] Furthermore, the cylinder is controlled by an electromagnetic valve, and the signal of the electromagnetic valve is given by a pulse signal of a rotating shaft of a cigarette conveying line, so that the clapping action can be automatically controlled as the cigarette conveying line runs.

[0017] Furthermore, one end of the cigarette beating plate is configured as an arc-shaped plate, which protrudes toward a direction close to a tray unloading machine or a cigarette conveying line, and is used to gather the cigarettes inward to obtain a better deviation correction effect.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the utility model. Unless otherwise specified, all technical and scientific terms used in the utility model have the same meanings as those commonly understood by ordinary technicians in the technical field to which the utility model belongs. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] In a typical embodiment of the present application, a device for automatically straightening cigarette flow on a cigarette conveyor line is provided, such as Figure 1-5 As shown, it includes a cigarette clapper 1, which is designed in a Y shape and is used to contact and clapper the horizontal cigarettes and other cigarettes that are deviated outward in the conveying channel, so that the cigarettes are arranged neatly at the confluence of the tray unloading machine and the cigarette conveying line; a cylinder 3, which is connected to the cigarette clapper and controls the movement of the cigarette clapper; a fixing seat 5, which is used to be installed on the protective cover and is fixedly connected to the cylinder 3.

[0032] like Figure 1As shown, the Y-shaped cigarette beater 1 is arranged horizontally, and the branch plate extended at the upper end corresponds to the height of the cigarettes on the unloader, and the lower branch plate corresponds to the height of the cigarette conveyor line. It can block the cigarettes on the two conveying branches respectively and arrange them neatly at the confluence to avoid squeezing and deformation of the cigarettes or blockage of the conveyor line.

[0033] To better block and align the cigarette, Figure 2 As shown, at one end of the cigarette slapping plate 1 near the cigarette source, the ends of the upper and lower branch plates are both set as arc-shaped plates 7 that are concave inward and convex outward, and the outer convexity of the arc-shaped plates 7 is used to gather the cigarettes that deviate to the outside into the conveyor line, and then the flat plate part of the cigarette slapping plate is used to align them. Preferably, the curvature of the arc-shaped plate is set to 15° to achieve efficient deviation correction of cigarettes in the tray unloader.

[0034] The cylinder 3 is arranged on one side of the cigarette clapper 1. In order to make the cigarette clapper be evenly stressed during the clapping process, the cylinder 3 is bolted to the cigarette clapper 1 through the U-shaped mounting plate 2. The opening side of the U-shaped mounting plate 2 faces the cylinder, and one end of the cylinder 3 is embedded in the U-shaped opening of the U-shaped mounting plate. In order to facilitate observation of the arrangement of cigarettes on the cigarette conveyor line, the cigarette clapper is made of a transparent acrylic plate. Bolt holes are provided on the connecting surface of the U-shaped mounting plate for connecting and fixing the cylinder and the cigarette clapper.

[0035] like Figure 3 As shown, two parallel baffles are arranged on the U-shaped mounting plate 2, and a certain interval is provided between the parallel baffles to form an accommodating cavity. The cylinder 3 is arranged in the accommodating cavity and fixedly connected to the U-shaped mounting plate 2, so as to facilitate the positioning of the cylinder during installation. At the same time, the cylinder can be limited to prevent the horizontal movement of the cylinder from affecting the beating effect.

[0036] The action of the cylinder is controlled by the solenoid valve, and the action of the solenoid valve is controlled by the pulse signal and the logic controller sent from the rotating shaft of the cigarette conveyor line, so as to realize the automatic control of the clapper action as the cigarette conveyor line runs. Specifically, a pulse trigger is installed next to the conveyor roller of the conveyor belt. Every time the rotating shaft of the conveyor roller rotates one circle, it triggers a detection pulse input, and then the edge-triggered pulse width trigger relay of the intelligent logic controller is used for logic control. The specific control method can be realized by the existing technology. For example, the intelligent logic controller can be realized by SI EMENS LOGO! 12 / 24RC6ED1052-1MD00-0BA model. This logic controller has 8 digital inputs and 4 relay outputs. It is cheap and fully meets the needs.

[0037] In a preferred embodiment, the production speed of the cigarette making machine can be set to 6000 cigarettes / minute. At the converging and lifting part of the conveyor line, the conveyor roller shaft is set to rotate once in about 6.1 seconds, that is, the input detection pulse is reset once every 6.1 seconds; the relay TH is set to 0.5 seconds, and the TL is set to 1 second. During the TH period, the relay outputs a high level to control the solenoid valve to operate. The solenoid valve operates, and then controls the cylinder on the straightening device to start, and the cigarette clapboard moves forward to process the cigarettes neatly. In this way, within one detection cycle, the clapboard hits the cigarettes 4 times in total. When the conveyor belt stops, the clapboard stops and stays away from the cigarettes.

[0038] In order to reset the cigarette clapper after it is struck, a tension spring 6 is installed in the concave surface of the U-shaped mounting plate 2. After the cylinder drives the cigarette clapper to be struck outward, the tension spring 6 contracts and drives the clapper to reset and wait for the next pulse signal. At the same time, the tension spring is also helpful to ensure the smooth movement of the clapper when the cylinder is started.

[0039] Specifically, the cylinder 3 is mounted on the cylinder mounting box 4, as shown in FIG. Figure 4 As shown, the cylinder mounting box 4 is a semi-enclosed structure, and the cylinder 3 is mounted on the back of the cylinder mounting box, that is, on the side away from the opening, and is fixedly connected. A long first waist hole is formed on the bottom surface of the cylinder mounting box 4, and the first waist hole extends horizontally toward the side close to the cigarette clapper. The cylinder mounting box 4 is bolted to the fixing seat 5 through the first waist hole, so that the cigarette clapper can be adjusted inward and outward in the horizontal direction.

[0040] like Figure 5 As shown, a second long waist hole is opened in the vertical direction of the fixing seat 5, and the fixing seat is connected with the protective cover bolts through the second waist hole, so that the cigarette beater can be adjusted up and down.

[0041] In this embodiment, the U-shaped mounting plate 2, the cylinder mounting box 4 and the fixing seat 5 are all made of stainless steel and have sufficient rigidity.

[0042] The utility model realizes the neat beating of the cigarette flow in the conveying channel of the online equipment, reduces the probability of horizontal cigarettes and cigarette squeezing and deformation during cigarette conveying, effectively reduces the shutdown rate of the cigarette warehouse of the packaging machine, provides a guarantee for the appearance quality of the cigarettes, and improves the production efficiency of the equipment.

[0043] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
