Description

Side pushes away material conveying mechanism of position adjustable

Technical Field

The utility model relates to a mechanism for conveying materials, in particular to a material conveying mechanism applied to a packaging machine.

Background

In a material conveying mechanism of a packaging machine, a stopping part for stopping the material from advancing is often required to be arranged at the tail end of a material conveying channel, an interruption part for interrupting the follow-up material from advancing towards the stopping part is arranged at the upstream of the stopping part, a side pushing part is arranged between the interruption part and the stopping part, and the material stopped between the interruption part and the stopping part is pushed out of the conveying channel laterally by the side pushing part.

In the material conveying mechanism of the existing packaging machine, the position of the side pushing piece away from the interruption piece is fixed. In the case of a defined material size, it is sufficient to fix the lateral thrust element in a defined position in order to determine its range of action. However, if the material is easily deformed by pressure, the material is compressed less by the compression of the material before and after the material is stopped by the stopping member. Each material is reduced a little, and finally, redundant materials enter the action range of the side pushing piece, and the side pushing piece can collide with the redundant materials in the process of pushing the materials. The resulting consequences are that the material is skewed, which brings adverse effects to the subsequent packaging process, and that the packaging machine is stopped because the skewed material blocks a certain component.

Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Fig. 1 to 7 show a top view of the material conveying mechanism. As shown in fig. 1, the material conveying mechanism with adjustable side pushing position comprises a conveying channel consisting of an endless belt 1 and a row of rollers 2 arranged side by side. The endless belt 1 receives the materials continuously fed from the upstream mechanism and drives the materials to move in sequence. The drum 2 is a freely rotatable drum that is not powered. After the materials are driven by the circulating belt 1 to move to the roller 2, the materials slide on the roller 2 one by means of the pushing force of the rear materials on the front materials.

Referring to fig. 1, a stop 3 is provided near the end of the conveyor channel to stop the travel of material. Upstream of the stop 3, a stop 4 is provided to stop further material from proceeding towards the stop 3. The interrupters 4 of the present embodiment are provided on the left and right sides of the endless belt 1, and the interrupters 4 are connected to the air cylinders 5. The interruption piece 4 is not activated when the material between the interruption piece 4 and the interruption piece 3 is not yet full. After the material stopped between the interruption piece 4 and the interruption piece 3 is fully squeezed, as shown in fig. 2, the cylinder 5 pushes the interruption piece 4, so that the interruption piece 4 clamps the material from the left and right sides of the material, and the subsequently sent material is blocked from continuing to advance towards the interruption piece 3.

Referring to fig. 1, a side push 6 is provided beside a row of rollers 2. The side pushing piece 6 is L-shaped as a whole. The side of the L shape directly contacting with the material is a telescopic rod 6a with adjustable length. The other side of the "L" shape is connected to a slide 8 by means of a screw 7. The slide member 8 is slidably connected to a guide rail (not shown) fixed to the frame. The side pusher 6 is moved by the slide 8, so that the material stopped between the stop 4 and the stop 3 is pushed laterally by the side pusher 6 away from the conveying channel in the direction indicated by the arrow in fig. 1. The mechanism for driving the sliding member 8 to move may be a transmission mechanism such as a timing belt or a chain.

Referring to fig. 1, the axis of the screw 7 is perpendicular to the direction in which the sliding member 8 moves the side pushing member 6, i.e. perpendicular to the direction indicated by the arrow in fig. 1. One end of the screw 7 is in threaded connection with the sliding part 8, and the other end is in axial fixed connection with the side pushing part 6 but can rotate circumferentially. The position of the side thrust piece 6 from the interruption 4 can be adjusted by turning the screw 7. As an equivalent structural variation, one end of the screw 7 may be screwed with the side pushing member 6, and the other end may be axially fixedly connected with the sliding member 8 but circumferentially rotatable.

The function of the side pushing part to adjust the position of the interrupting part is explained in detail below by combining the working principle of the material conveying mechanism.

Referring to fig. 2, material continuously fed from an upstream mechanism is received by the endless belt 1, and the endless belt 1 drives the material to sequentially advance toward the drum 2. After the materials move to the roller 2, the materials slide on the roller 2 one by means of the extrusion force of the materials at the rear part to the materials at the front part until the materials are finally stopped by the stopping part 3. When the material stopped between the stopper 4 and the stopper 3 is crowded, as shown in fig. 2, the stopper 4 grips the material from both the left and right sides of the material, thereby blocking the subsequently fed material from continuing to advance toward the stopper 3.

For materials that do not deform under pressure or that deform only to a small extent, the distance between the interruption 4 and the stop 3 determines the amount of material that is stopped between the interruption 4 and the stop 3. Taking fig. 2 as an example, the materials a-G are the materials intercepted between the interruption 4 and the interception 3. That is to say, in the ideal case of no deformation of the material, the side thrust pieces 6 only have an action range related to the materials a-G. The side push 6 will not collide with the material H blocked by the interruption during the process of pushing the materials a-G out of the conveying channel.

However, for materials that are susceptible to crush, the situation shown in FIG. 3 occurs. As shown in fig. 3, the materials a-G stopped between the stopper 4 and the stopper 3 are compressed less by the squeezing action of the front and rear materials, so that the materials H that should not enter the action range of the side pusher also enter the action range of the side pusher 6. In this case, if the side push 6 pushes the materials a-G in the direction indicated by the arrow in fig. 3, the side push 6 will hit the excess material H, with undesirable consequences. It should be added that the interruption piece 4 is designed to clamp the material H after it has been filled with the materials a-G, which have already been compressed and deformed during the successive filling of the materials a-G. Therefore, although the interruption piece 4 clamps the material H, it is not possible to avoid the material a-G from being crushed to be small, and the material H cannot be prevented from entering the action range of the side pushing piece 6.

In order to prevent the side pusher 6 from colliding with the excess material H during the pushing of the materials a-G, as shown in fig. 3, the position of the side pusher 6 from the breaker 4 may be adjusted in advance, as shown in fig. 4. The distance between the side pushing piece 6 and the interruption piece 4 is increased by rotating the screw 7, so that the material H cannot enter the action range of the side pushing piece 6, the side pushing piece 6 is prevented from colliding with the material H in the process of pushing the materials A-G, and adverse consequences caused by the fact that the side pushing piece collides with redundant materials are avoided. Fig. 4 shows the state of the side pushing member 6 after the sliding member 8 pushes the materials a-G away from the conveying channel.

As a further development, see fig. 5, the stop 3 is connected to a displacement mechanism 9. Whenever the material stopped between the interruption 4 and the interruption 3 is full and the interruption 4 blocks the travel of the subsequent material, the moving mechanism 9, as shown in fig. 6, drives the interruption 3 to retract away from the interruption 4, so that the distance between the interruption 3 and the interruption 4 increases, thereby releasing the pressure on the material a-G which was originally squeezed between the interruption 4 and the interruption 3, and also the squeezing force between the material H which was blocked by the interruption and which is closest to the interruption and the material G which is not blocked by the interruption and which is closest to the interruption. Therefore, the materials A-G which are originally compressed and reduced can be automatically restored to the original size, and when the side pushing piece 6 pushes the materials A-G away from the conveying channel, the friction force between the materials H and the materials G can be greatly reduced because the pressure between the materials H and the materials G is released, so that various adverse effects such as material deformation and even abrasion caused by the friction force are avoided. The moving mechanism 9 can be selected as an air cylinder, a servo motor or other driving structures. The moving mechanism 9 of the embodiment shown in fig. 5 uses a pneumatic cylinder, which drives the retraction and resetting of the break 4.

In a preferred embodiment, the transfer passage is divided into a powered upstream section and a non-powered downstream section, the downstream section having a beginning adjacent the end of the upstream section and the downstream section being separated from the upstream section by a boundary downstream of the interrupter and upstream of the stop. For example, as shown in fig. 5, the upstream section of the conveying channel is a power-driven endless belt 1, the downstream section of the conveying channel is a row of rollers 2 which are not power-driven, and the boundary 10 between the endless belt 1 and the rollers 2 is located downstream of the interruption part 4 and upstream of the stopping part 3. The advantage of this arrangement is that after the interruption 4 has blocked the travel of the following material as shown in fig. 6, the upstream section of the conveying channel can still maintain the driving force for moving the material, i.e. the endless belt 1 can still be running, so that the endless belt 1 still has a pushing force on the part G, F of the material captured between the interruption and the interception close to the interruption 4, so that after the retraction of the interception 3, as shown in fig. 7, the material a-G captured between the interruption 4 and the interception 3 remains always tightly aligned under this pushing force and is not affected by the retraction of the interception 3. Furthermore, as shown in fig. 7, the pushing force pulls the material H blocked by the blocking member from the first material row to the next material G not blocked by the blocking member, so that when the side pushing member 6 pushes the material a-G blocked between the blocking member and the blocking member laterally away from the conveying passage, the pushed-away material G is not in contact with the material H remaining in the conveying passage at all, and no friction exists between the two materials, thereby more thoroughly avoiding adverse effects caused by the friction.

It should be noted that the powered upstream section is not limited to an endless belt, and may be, for example, a row of powered rollers. The unpowered downstream section is not limited to rollers and may be, for example, a smooth plate along which the material is caused to slide.

It should be noted that the interrupting member according to the present invention is not limited to the illustrated embodiment, and may be, for example, a flap that moves up and down, and that blocks the flap when the flap moves down to the lowest position.

It should be noted that each drawing is a schematic diagram of the conveying mechanism, and some configurations not related to the object of the present invention are omitted. For example, the conveying mechanism is also usually provided with a guide member driven by a cylinder and moving synchronously with the side pushing member, and the guide member leans beside the material and moves along with the material while the side pushing member pushes the material away from the conveying passage, and plays a role of preventing the material from deviating from the moving route.

It should be noted that a packaging machine may be provided with a plurality of conveying channels, the plurality of conveying channels are arranged side by side, and each conveying channel is provided with the interrupting piece, the side pushing piece, the sliding piece, the stopping piece and the moving mechanism connected with the stopping piece.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the utility model. The protection scope of the present invention should be subject to the appended claims.
