Abstract

A middle position alignment system for alignment and attachment of two layers of paperboards. When an upper sensor senses that a front end of an upper layer paperboard arrives or a lower sensor senses that a front end of a lower layer paperboard arrives, a servo motor (4) is started and drives an upper lay gauge (31) and a lower lay gauge (32) to move at a same time, to enable the upper lay gauge (31) and the lower lay gauge (32) to move to a convergent location (1) at a same time. Since the paperboards are conveyed rapidly, the upper layer paperboard can catch up and stop against the upper lay gauge (31), the lower layer paperboard can also catch up and stop against the lower lay gauge (32), and therefore the front end of the upper layer paperboard and the front end of the lower layer paperboard can also meet at the convergent location (1) and attached to each other. According to the middle position alignment system, the same servo motor is used for driving the upper lay gauge (31) and the lower lay gauge (32) at the same time, so that alignment is more accurate, and the middle seat alignment system is simple in structure and convenient to install and maintain.

For example, the invention patent of the Chinese Patent No. 201520200754.1, which the applicant has previously applied for, discloses a mid-seat transmission alignment mechanism. However, the disadvantage of the middle seat transmission alignment mechanism is that after a period of use, the rotating shaft is easily worn, resulting in a gap between the rotating shaft and the chain transmission aligning component, thereby causing the left and right sides to be out of synchronization, that is, the alignment Inaccurate; also, because the long shaft is to pass through the left and right mechanisms, and many parts are connected, when the shaft is worn, it will cause the parts to be distracted, even jamming the parts, causing damage to other parts, and this structure is complicated. It is not convenient to install, maintain, etc.

detailed description

The mid-seat alignment system of the present invention can be applied as a single system. For example: an upper conveyor belt for conveying upper paperboard and a lower conveyor belt for conveying lower cardboard. An arrival position is provided before the intersection in the conveying direction of the upper conveyor belt and the lower conveyor belt. An upper stop gauge for blocking the front end of the upper cardboard is disposed between the arrival position and the intersection in the conveying direction of the upper conveyor belt, and the upper gauge is movable, and the moving direction of the upper gauge is consistent with the conveying direction of the upper conveyor belt. Further, the moving speed of the upper gauge is slower than the conveying speed of the upper conveyor belt, so that the front end of the upper cardboard can be pressed against the upper gauge before the upper gauge is moved to the intersection. A lower gauge for blocking the front end of the lower cardboard is disposed between the arrival position and the intersection in the conveying direction of the lower conveyor belt, and the lower gauge is movable, and the moving direction of the lower gauge is consistent with the conveying direction of the lower conveyor belt. Further, the moving speed of the lower gauge is slower than the conveying speed of the lower conveyor belt, so that the front end of the lower cardboard can withstand the lower gauge before moving the lower gauge to the intersection. The center seat alignment system further includes a servo motor for driving the upper and lower gauges, and the servo motor is connected to the upper and lower gauges through the transmission mechanism. An upper sensor for detecting whether the front end of the upper cardboard is reached is mounted at the arrival position of the upper conveyor, and a lower sensor for detecting whether the front end of the lower cardboard arrives is mounted at the arrival position of the lower conveyor.

When the upper sensor senses that the front end of the upper cardboard arrives or the lower sensor senses that the front end of the lower cardboard arrives (one of which arrives or arrives at the same time), the servo motor starts and drives The upper and lower gauges move at the same time, so that the upper and lower gauges move to the intersection at the same time. Because the conveying speed of the cardboard is faster, the upper cardboard can catch up and resist the upper gauge, and the lower cardboard can also catch up and resist the lower gauge, so that the front end of the upper cardboard and the front end of the lower cardboard are also at the same time. Hand over and fit.

Preferably, the transmission mechanism comprises a belt transmission device, an upper sprocket transmission for driving the upper gauge, a lower sprocket transmission for driving the lower gauge, and an upper sprocket transmission provided with an upper transmission shaft for driving, The lower sprocket transmission is provided with a lower drive shaft for driving, and the servo motor simultaneously drives the upper drive shaft and the lower drive shaft through a belt drive. The belt drive is used to decelerate the rotation of the servo motor output and synchronously drive the upper sprocket drive and the lower sprocket drive. This transmission mechanism is simple in structure and easy to install and maintain.

The mid-seat alignment system of the present invention can also be applied simultaneously in multiple systems. As shown in FIG. 1, the present invention also provides a mid-seat alignment device comprising two mid-seat alignment systems as described above. The two mid-seat alignment systems are respectively the left middle seat alignment system for supporting the left side of the cardboard, and the right middle seat alignment system for supporting the right side of the cardboard. Preferably, the left center seat alignment system is symmetrically disposed with the right center seat alignment system. The following is a description of the right center seat alignment system.

As shown in Figures 2 to 4, the right center seat alignment system includes an upper conveyor belt for conveying the upper paperboard and a lower conveyor belt for conveying the lower cardboard. Arrival 2 is provided before the intersection 1 in the conveying direction of the upper conveyor belt and the lower conveyor belt.

An upper stop 31 for blocking the front end of the upper cardboard is disposed between the arrival position 2 in the conveying direction of the upper conveyor belt and the intersection 1, and the upper gauge 31 is movable and the moving direction of the upper gauge 31 and the upper conveyance are provided. The conveying direction of the belt is uniform. Further, the moving speed of the upper gauge 31 is slower than the conveying speed of the upper conveyor belt, so that the front end of the upper cardboard can be pressed against the upper gauge 31 before the upper gauge 31 is moved to the junction 2, The blocking of the upper gauge 31, therefore, even if the conveying speed of the upper conveyor belt is fast, the upper cardboard can only move with the upper gauge 31 at this distance (between the upper gauge and the intersection).

Between the arrival position 2 in the conveying direction of the lower conveyor belt and the intersection 1 is provided for blocking The lower stop 32 of the lower cardboard front end is movable, and the movement direction of the lower gauge 32 is consistent with the conveying direction of the lower conveyor belt. Further, the movement speed of the lower gauge 32 is higher than that of the lower conveyor belt. The speed is slow, so that the front end of the lower cardboard can be pressed against the lower gauge 32 before moving to the intersection 1. Due to the blocking of the lower gauge 32, even if the conveying speed of the lower conveyor is faster, the lower cardboard At this distance (between the lower gauge and the junction), it can only move with the lower gauge 32.

The right center seat alignment system B further includes a servo motor 4 for driving the upper gauge 31 and the lower gauge 32. The servomotor 4 is drivingly coupled to the upper gauge 31 and the lower gauge 32 via a transmission mechanism. The arrival position 2 of the upper conveyor belt is mounted with an upper sensor for detecting whether the front end of the upper cardboard is reached, and the arrival position 2 of the lower conveyor belt is mounted with a lower sensor for detecting whether or not the front end of the lower cardboard arrives.

As shown in FIGS. 5 and 6, when the upper sensor senses that the front end of the upper cardboard 51 arrives or the lower sensor senses that the front end of the lower cardboard 52 arrives (one of which arrives or arrives at the same time) (see FIG. 5). The servo motor 4 starts and drives the upper gauge 31 and the lower gauge 32 to move at the same time. Since the conveying speed of the cardboard is relatively fast, the upper cardboard 51 can catch up against the upper gauge 31, and the lower cardboard 52 can also catch up and abut the lower gauge 32, so that the front end of the upper cardboard 51 and the lower cardboard 52 The front end is also handed over at the intersection 1 and fits together (Figure 6).

This structure makes the upper cardboard and the lower cardboard that need to be fitted together. No matter who arrives at the respective arrival position or arrives at the same time, the upper cardboard can be caught up before the upper and lower gauges move to the intersection. Resist the upper gauge and the lower cardboard to catch up and resist the lower gauge. For example, if the upper cardboard reaches the arrival position of the upper conveyor belt, the servo motor starts and drives the upper and lower gauges to move at the same time. Thus, the upper cardboard will catch up and resist the upper gauge, and the lower cardboard will be slower. Only after catching up and resisting the lower gauge, but because of the blockage of the upper gauge, the upper cardboard will not arrive at the junction first, but the upper cardboard and the lower cardboard will arrive at the junction at the same time with the upper and lower gauges. Achieve accurate alignment.

Preferably, as shown in FIGS. 2 to 4, the transmission mechanism includes a belt transmission 61 for driving The upper sprocket transmission 62 of the upper gauge 31 and the lower sprocket transmission 63 for driving the lower gauge 32. The upper sprocket transmission 62 is provided with an upper transmission shaft 621 for driving, and the lower sprocket transmission 63 is provided with a lower transmission shaft 631 for driving, and the servo motor 4 simultaneously drives the upper transmission shaft 621 and the lower transmission shaft through the belt transmission 61 631. Specifically, the operation of the lower sprocket transmission 63 is such that the lower drive shaft 631 drives the chain through the sprocket, the chain is mounted on the inner side of the lower conveyor belt, and the lower gauge 32 (which may be a plurality of) is mounted on the chain. The lower stop 32 can be circulated at a distance before the intersection 1 to block the lower layer of cardboard continuously conveyed by the lower conveyor belt. Similarly, the working process of the upper sprocket transmission 62 is the same and will not be described herein. This transmission mechanism is simple in structure and easy to install and maintain.

Preferably, the upper sensor and the lower sensor are photoelectric sensors, and the photoelectric sensor is sensitive and accurate, so that the alignment of the present invention is more accurate; the upper conveyor belt is inclined, and the lower conveyor belt is horizontal. Conveyed for production and so on.
