Description

Technical fields:

[0001] This invention relates to a cigarette pack guiding and separating device. Background technology:

[0002] The inlet of the small-pack transparent packaging machine in the ZB47 and GD series cigarette packaging machinery basically adopts a rotary steering and positioning system. This system, which involves mechanical, electrical, and pneumatic components, is characterized by numerous mechanisms, complex structure, high precision requirements, and a cumbersome transmission system. These characteristics result in low reliability, frequent failures, cumbersome operation, and poor material adaptability. According to incomplete statistics, this part experiences more than 8 downtimes per shift, with maintenance and adjustment time exceeding 15 minutes, making it the most significant factor affecting equipment operation. Due to its structure and operating principle, the electrical requirements are particularly high. Its structure is overly complex compared to the clear and simple function of cigarette pack positioning and steering. Given its high failure rate and high electrical requirements, it is absolutely necessary and imperative to design a new mechanism with a simpler structure and more stable performance to replace it. Summary of the Invention:

[0003] The present invention provides a cigarette pack guiding and separating device to solve the problems existing in the prior art. The device can flexibly separate the longitudinally conveyed cigarette pack flow into individual packs and realize the right-angle turning function.

[0004] The technical solutions adopted in this invention are as follows:

[0005] A cigarette pack guiding and separating device includes a guide rail, a pressure plate, a separating plate, and a buffer plate. The separating plate is disposed on one side of the guide rail and has a separating hole. One end of the buffer plate is disposed above the guide rail, and the other end is floatingly supported on the separating plate. The buffer plate is arranged at an angle downward from the guide rail toward the separating plate. The pressure plate is disposed above the buffer plate and moves back and forth through the buffer plate toward the separating hole. The cigarette pack is fed between the separating plate and the buffer plate by the guide rail, and the reciprocating motion of the pressure plate presses the cigarette pack into the separating hole and causes it to fall away.

[0006] Furthermore, the end of the guide rail is provided with a hinge lug, and both the pressure plate and the buffer plate are hinged to the hinge lug.

[0007] Furthermore, a guide stud is provided on the separation plate, and a waist-shaped hole is provided on the buffer plate. The guide stud passes through the waist-shaped hole and is threaded onto the separation plate. A spring is fitted on the guide stud and is positioned above the buffer plate.

[0008] Furthermore, the separation plate is provided with a support platform, the bottom end of the buffer plate is supported on the support platform, and the guide stud is threadedly connected to the support platform.

[0009] Furthermore, the wall surface of the separation hole near the support platform is a downwardly sloping structure.

[0010] Furthermore, the buffer plate is provided with a rectangular hole, and the pressure plate reciprocates within the rectangular hole toward the separation hole.

[0011] Furthermore, two guide rods are provided on one side of the guide rail and below the buffer plate, and the inclination angle of the two guide rods is equal to the inclination angle of the buffer plate.

[0012] Furthermore, the pressure plate is driven by a crank mechanism or by the reciprocating motion of a cylinder shaft.

[0013] The present invention has the following beneficial effects:

[0014] This separation device can separate the longitudinally conveyed tobacco packages and then transport them laterally to the next process, ensuring product quality and significantly reducing contact rate during the tobacco package transport process. This invention features a simple structure, convenient operation, reliable use, long service life, and prevents tobacco packages from being squeezed and deformed during separation. It has a low failure rate, wide adaptability, requires no maintenance, is low-cost, easy to use, and readily promoted. The invention incorporates a buffer plate to reduce the impact of the tobacco package flow on the end packages. The buffer plate's inclination guides the tobacco packages, and the plate rotates arbitrarily around an axis at one end, with a spring at the other end allowing the forward-conveyed tobacco packages to adaptively achieve a buffering function. A pressure plate performs intermittent reciprocating rotation, pushing the tobacco packages onto the downstream conveyor belt while simultaneously stopping subsequent tobacco packages. When the pressure plate lifts and releases the subsequent tobacco package flow, further transport is achieved. Attached image description:

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] like Figures 1 to 4This invention discloses a cigarette pack guiding and separating device, comprising a guide rail 1, a pressure plate 2, a separating plate 3, and a buffer plate 4. The separating plate 3 is disposed on one side of the guide rail 1 and has a separating hole 31. One end of the buffer plate 4 is hinged above the guide rail 1, and the other end is floatingly supported on the separating plate 3. The buffer plate 4 is arranged at an angle downward from the guide rail 1 toward the separating plate 3. The pressure plate 2 is placed above the buffer plate 4 and has a rectangular hole 41. The pressure plate 2 reciprocates within the rectangular hole 41 toward the separating hole 31. A cigarette pack 10 is fed between the separating plate 3 and the buffer plate 4 by the guide rail 1, and the reciprocating motion of the pressure plate 2 presses the cigarette pack into the separating hole 31 and causes it to fall away.

[0021] Two hinge ears 11 are provided at the end of the guide rail 1, and a pin is inserted between the two hinge ears 11. The pressure plate 2 and the buffer plate 4 both rotate on the pin.

[0022] To enable the buffer plate 4 to float and be supported on the separation plate 3, a guide stud 31 is provided on the separation plate 3, and a waist-shaped hole is provided on the buffer plate 4. The guide stud 31 passes through the waist-shaped hole and is threaded onto the separation plate 3. A spring 5 is sleeved on the guide stud 31 and is positioned above the buffer plate 4.

[0023] A support platform 32 is provided on the separation plate 3. The buffer plate 4 is tilted under its own weight. The bottom end of the buffer plate 4 is supported on the support platform 32. The guide stud 31 is threadedly connected to the support platform 32.

[0024] When the pressure plate 2 presses against the cigarette pack 10 and causes the cigarette pack 10 to fall into the separation hole 31, in order to avoid scratching the cigarette pack 10 and to facilitate the flipping of the cigarette pack 10, the wall surface of the separation hole 31 on the side near the support platform 32 is a downward inclined slope structure.

[0025] When the cigarette pack enters between the separating plate 3 and the buffer plate 4, two guide rods 6 are provided on one side of the guide rail 1 and below the buffer plate 4 to guide the movement of the cigarette pack 10. The inclination angle of the two guide rods 6 is equal to the inclination angle of the buffer plate 4. The guide rods 6 can guide the direction of the cigarette pack, ensuring that the conveyed cigarette pack is always below the buffer plate 4 and that the cigarette pack does not tilt.

[0026] In this invention, the reciprocating motion of the pressure plate 2 is achieved by a crank mechanism (eccentric crank disc) or by the reciprocating motion of the cylinder shaft of a cylinder.

[0027] In use, when the upstream cigarette pack 10 is supplied to the downstream small transparent paper packaging machine, the buffer plate 4 on the cigarette pack conveying guide rail 1 is lifted. The spring 5 above the buffer plate 4 offsets the impact force when the upstream cigarette pack is conveyed. After the cigarette pack passes the buffer plate 4, it enters the separation plate 3. The guide rods 6 on both sides of the separation plate 3 guide the cigarette pack to be sent onto the separation plate 3 below the buffer plate 4. Finally, the reciprocating pressure plate 2 separates the cigarette pack from the original conveying line, and at the same time prepares for the next process flow (cigarette pack stepping lateral conveying).

[0028] This separation device can separate the longitudinally conveyed tobacco packages and then transport them laterally to the next process, ensuring product quality during the tobacco package conveying process and significantly reducing the contact rate. This invention features a simple structure, convenient operation, reliable use, long service life, and prevents tobacco packages from being squeezed and deformed during separation. It has a low failure rate, wide adaptability, requires no maintenance, is low in cost, and is easy to use and promote. This device solves many defects such as frequent failures, cumbersome operation, and high maintenance rates. Its simple structure and transmission require no manual operation, and it has wide adaptability and requires no maintenance.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
