In the description of the following specific embodiment, referring to fig. 1, for convenience of explanation, a direction in which the tray 8 is conveyed along the transplanting conveying device is defined as a conveying direction X. The conveyance direction mentioned later refers to the X direction. In the horizontal plane, the direction perpendicular to the X direction is the Y direction, which is also the width direction of the transplanting conveying device. The Z direction is perpendicular to the XY plane, and the Z direction is the lifting direction of the elevating table 6 described later.

Referring to fig. 1, an embodiment of the present utility model provides a transplanting and conveying device for completing the transplanting of a pallet 8 between a forklift fork taking station and a stacker taking and placing station. The transplanting conveying device comprises a mounting frame 1, a protection assembly 3, a conveying roller assembly 4 and at least two conveying chains 2. The mounting frame 1 is fixedly arranged on the ground or a fixed object. Each conveyor chain 2 is rotatably mounted to the mounting frame 1. The guard assembly 3 is mounted to the mounting frame 1, the guard assembly 3 comprising at least two guard members 31, each conveyor chain 2 being located between two guard members 31. The conveying roller assembly 4 is mounted on the mounting frame 1 and is positioned in the middle of the two conveying chains 2.

The mounting frame 1 provides a mounting and carrying foundation for other components for supporting the entire transplanting conveyor. The mounting frame 1 comprises legs and mounting beams mounted on top of the legs. The landing leg and the mounting beam can be made of metal materials, so that the support strength is high, and the service life is long. The support leg is fixedly connected to the ground or other fixed objects through bolts and the like. The mounting beam is supported by the support legs and is used for mounting the conveying chain 2, the protection assembly 3 and the conveying roller assembly 4. The mounting beam is kept horizontal to ensure the level of the conveyor chain 2.

The conveyor chains 2 extend from one end of the mounting beam to the other end of the mounting beam, two conveyor chains 2 are arranged at intervals along the width direction of the transplanting conveying device, and the two conveyor chains 2 correspond to two edges of the width direction of the tray 8. The width direction of the tray 8 and the width direction of the transplanting conveyor are parallel. The tray 8 is placed above the conveying chain 2, and the tray 8 is driven to move from the upstream end to the downstream end of the mounting frame 1 by the rotation of the conveying chain 2. The upstream end of the mounting frame 1 corresponds to a forklift, and the downstream end of the mounting frame 1 is abutted against the lifting platform 6.

It should be noted that, in some embodiments, the number of the conveying chains 2 is larger, and a plurality of conveying chains 2 are arranged along the X direction, that is, the conveying direction. Therefore, the temporary storage station of the tray 8 can be increased, and the continuity of the warehouse-out and warehouse-in actions of the tray 8 is improved.

The complete moving process of the tray 8 is that the tray 8 is transferred onto the conveying chain 2 from a forklift, then is moved from the upstream end to the downstream end along the conveying chain 2, and then is transferred onto the lifting table 6, and the lifting table 6 drives the tray 8 to lift, so that the tray 8 can be in butt joint with the subsequent process.

The protective assembly 3 is used for preventing the tray 8 from deviating during the conveying process and guiding the tray 8 when the lifting platform 6 described later acts. The guard assembly 3 is located at the most edge in the width direction of the mounting frame 1, and the guard assembly 3 includes two guard members 31, for example, each guard member 31 has a plate-like structure. When the tray 8 is placed on the conveying chain 2, the protection component 3 plays a role in protecting the tray 8 from two sides, and prevents the tray 8 from falling from two sides of the width of the mounting frame 1. The height of the protection component 3 is higher than that of the conveying chain 2, the protection component 3 can block and protect the tray 8 and finished cigarettes placed on the tray 8, and the conveying stability and reliability of the tray 8 are improved. The length of the protection component 3 is greater than or equal to that of the conveying chain 2, and the protection component 3 can play a protection role on the tray 8 in the conveying direction of the whole conveying chain 2.

The supporting surface of the conveying roller assembly 4 is 2 mm-4 mm lower than the supporting surface of the conveying chain 2, specifically, for example, 2mm, 3mm or 4mm lower. When the pallet 8 is bent downwards due to the fact that the gravity center of the pallet 8 is concentrated, the conveying roller assembly 4 can effectively support the pallet 8, and as each roller 42 of the conveying roller assembly 4 can rotate freely, the conveying roller assembly can rotate freely through bearings, rolling friction is adopted between the pallet 8 and the rollers 42, excessive friction force is not generated on the pallet 8, and the fact that the pallet 8 cannot be jammed in the conveying process is guaranteed.

The function of the conveyor roller assembly 4 is to support the widthwise middle region of the tray 8 so that the middle region of the tray 8 will not be depressed when the tray 8 is carrying a weight. The conveyor roller assembly 4 includes a plurality of rollers 42. Along the length of the mounting frame 1, a plurality of rollers 42 are arranged. When the tray 8 is conveyed along the conveying chain 2, the conveying roller assembly 4 always plays a role in supporting the middle area of the width direction of the tray 8, so that the edge and the middle area of the width direction of the tray 8 can be supported.

With continued reference to fig. 1, the feed roller assembly 4 includes a support frame 41 and a plurality of rollers 42. The roller 42 is free to rotate relative to the support 41. Each roller 42 is mounted to both side plates by respective mounting shafts. Specifically, the rollers 42 with phi 60 mm and 150mm are arranged on the side plates at intervals of 170mm, and after the rollers 42 are arranged, the upper surfaces of the rollers 42 are just lower than the chain conveying surface by 2 mm-4 mm in design size. The conveyor roller assembly 4 need not be provided with power means. Therefore, the number of parts can be simplified on the premise of ensuring the support of the tray 8, so that the transplanting and conveying device is more compact.

The support frame 41 is fixedly mounted on the mounting frame 1, the support frame 41 comprises a bottom plate and side plates which are arranged in pairs, each side plate is mounted on the bottom plate in parallel, two ends of the support frame 41 along the conveying direction are open, and the top of the support frame 41 is also open. A plurality of rollers 42 are mounted between the side plates in a dispersed manner along the conveying direction. The top surface of the rollers 42 protrudes from the side plate, and the top surface of each roller 42 is flush. The bottom intermediate area of the tray 8 is in contact with the top surface of the roller 42.

The conveying roller assembly 4 can effectively support the Chinese character 'Chuan' shaped tray, and the probability of buckling deformation of the tray 8 is reduced. And the statistics is carried out after the whole warehouse moving operation is operated for a period of time, the damage rate of the Chinese character 'Chuan' type tray is very low, and the number of broken months is less than or equal to 5 per month.

With continued reference to fig. 1, the transplanting conveyor further comprises a first weight detecting element 5, the first weight detecting element 5 being mounted to one of the side plates and being located between the two side plates. The first weight detecting element 5 is used to detect whether the pallet 8 carries goods. The first weight detecting element 5 may be a mechanical detecting element such as a float load detecting switch. The mechanical switch has the least factor of being interfered by the field environment, is one of the most stable detection switches for detecting the conveying system, has more reliable detection structure and is more suitable for tobacco workshops.

The conveying roller assembly 4 is matched with the first weight detecting element 5, and when the position of the tray 8 needs to be detected, a small roller 42 of the conveying roller assembly 4 is canceled, so that an installation space is provided for the first weight detecting element 5, and the supporting of the whole section of conveying roller assembly 4 on the tray 8 is not influenced.

In some embodiments, the number of first weight detecting elements 5 is plural, and each first weight detecting element 5 corresponds to one tray 8. In the embodiment shown in fig. 1, the number of the first weight detecting elements 5 is two, one of the first weight detecting elements 5 is mounted to the upstream end portion of the conveying roller assembly 4, and the other first weight detecting element 5 is mounted to the downstream end portion of the conveying roller assembly 4. The length of the mounting 1 shown in fig. 1 allows two trays 8 to be placed, one for each first weight detecting element 5.

With continued reference to fig. 1 and fig. 2, the embodiment of the present utility model further provides a transplanting conveying system, including a lifting platform 6, a tray 8, and a transplanting conveying device provided by any one of the technical schemes of the present utility model. The elevating table 6 is installed downstream of the transplanting conveyor, and the elevating table 6 includes two sets of elevating posts 61 and a support plate 62 installed to each elevating post 61. The tray 8 is configured to be transported between the transplanting conveyor and the lifting table 6. Wherein the support length of the support plate 62 is greater than 80% of the length of the tray 8.

The support length of the support plate 62 refers to the maximum distance of both ends of the support plate 62 in the X direction, as illustrated by X1 and X2 in fig. 2. X1 and X2 may be equal or substantially equal. X1 and X2 are 80% or more of the width of the tray 8, for example, the width of the tray 8 is 1000mm, and then the length of X1 and X2 is 800mm or more, specifically, for example, about 810 mm. This dimension is the maximum length that ensures that the lifting platform 6 can be lowered normally. The distance between the inner side of the conveying chain 2 is 820mm, so that when the lifting platform 6 descends to the low position, a 5mm gap is reserved between the supporting plate 62 of the lifting platform 6 and two sides of the chain, and the supporting plate 62 of the lifting platform 6 is ensured not to scrape the chain.

When the Chinese character Chuan-shaped tray is placed on the lifting table 6, the width 810mm of the supporting plate 62 of the lifting table 6 is larger than 760mm of the inner distance between the cross beams at the two sides of the tray 8, and the left side and the right side are contacted by 25mm respectively. In the lifting action process, the two sides can support the tray 8, and the risk of side turning of the goods space is avoided. Likewise, when the field tray is placed on the lift table 6, the new support plate 62 does not affect the support of the field tray 8.

According to the scheme, the risk of rollover of the tray 8 is reduced, the reliability of supporting the tray 8 is improved, the support on two sides of the tray 8 is guaranteed not to rollover during lifting, when the lifting table 6 descends to a low position, the supporting plate 62 is still in the range of the inner side of the chain, the supporting plate 62 does not scrape the chain, and the lifting operation is not affected.

The trays 8 are divided into a Chuan-shaped tray and a Tian-shaped tray. For the Sichuan-shaped tray, three beams are arranged at the bottom of the Sichuan-shaped tray and are distributed along the width direction Y of the tray 8, and the supporting plate 62 can support the three beams at the bottom of the Sichuan-shaped tray without requiring uninterrupted support, so long as the three beams can be placed on the supporting plate 62. The three beams are supported, so that the probability of bending deformation of the middle part of the tray 8 can be reduced. The bottom of the letter-in-field tray is relatively flat, and the bottom of the letter-in-field tray can be certainly supported as long as the supporting plate 62 can support the bottom of the letter-in-field tray.

The lifting table 6 can lift and finish the lifting and transplanting of the pallet 8 between the height difference of the fork height of the conveying chain 2 and the stacker. When the lifting table 6 is lowered to the low position, the height of the supporting plate 62 is lower than the surface of the conveying chain 2, so that the transplanting of the tray 8 on the conveying chain 2 is not affected. The elevating platform 6 includes two sets of elevating posts 61, each set of elevating posts 61 being mounted with a support plate 62. Two positions in the length direction of the tray 8 are supported by the two sets of support plates 62 so that the tray 8 can be stably lifted.

Referring to fig. 6, the tray 8 is one of a channel tray and a field tray, as described above. The size of the tray is 1000 x 1250 x 150mm, and the bottom and the top of the tray are the same. The size of the III-shaped tray is 1000 x 1250 x 150mm, and the bottom of the III-shaped tray is provided with three beams, so that the novel forklift can adapt to an artificial forklift.

The bottom of the III-shaped tray is provided with three beams which are distributed along the width direction Y of the tray 8, two beams positioned at the edge are supported by the conveying chain 2, and the beam positioned in the middle is supported by the conveying roller assembly 4.

The first weight detecting element 5 is located upstream of the conveyor roller assembly 4, and the intermediate beam of the tray 8 may also press against the first weight detecting element 5, by means of which first weight detecting element 5 it is detected whether the tray 8 carries finished cigarettes.

With continued reference to fig. 1 and 2, the lift table 6 includes two lift posts 61, each lift post 61 having a support plate 62 mounted thereto. Each lifting column 61 is of a lifting structure, two lifting columns 61 can synchronously lift, and the lifting of the lifting columns is controlled by a set of components. The support plate 62 on which one of the lifting columns 61 is mounted is a single plate, and the support plate 62 on which the other lifting column 61 is mounted is two plate pieces 621 with a gap P between the two plate pieces 621. The elevating platform 6 further includes a second weight detecting element 7, and the second weight detecting element 7 is installed in the gap P between the two plate pieces 621. The second weight detecting element 7 is used to detect whether the tray 8 carries finished cigarettes. The second weight detecting element 7 can also adopt a floating ball load detecting switch, a mechanical detecting element and more stable detecting performance.

Fig. 2 is a schematic structural diagram of a pallet in a shape like a Chinese character 'Chuan' placed on a transplanting and conveying device provided by an embodiment of the present utility model, and fig. 3 is a schematic structural diagram of a pallet in a shape like a Chinese character 'Chuan' placed on a lifting table provided by an embodiment of the present utility model. The warehouse-in and warehouse-out processes of the Chinese character Chuan-shaped trays are described below.

The tray 8 presses the first weight detecting element 5 to complete the action of the travel switch, so that the purpose of detecting the goods space is achieved. The conveying chain 2 drives the chain to rotate positively and negatively through a motor, so that the tray 8 can be conveyed in two directions.

The pallet 8 warehouse-in process is that when the first weight detecting element 5 is not loaded and the lifting table 6 is at a low position, a forklift worker places the loaded pallet in a Chinese character 'Chuan' shape on the transplanting conveying equipment, then the first weight detecting element 5 detects the pallet 8 to generate corresponding material information and warehouse-in task information, the conveying chain 2 is driven to rotate positively, and the pallet 8 is moved towards the lifting table 6. When sagging is generated in the middle of the tray in the shape of a Chinese character Chuan, and the sagging height is more than 2mm, the conveying roller assembly 4 supports the beam in the middle of the tray 8, so that the tray 8 is prevented from continuing sagging. When the pallet 8 arrives at the stacker pickup position and the load is detected, the pallet 8 stops, which indicates that the pallet 8 is conveyed to the warehouse-in platform, the lifting platform 6 starts to lift to the stacker pickup height through the hydraulic system, the second weight detecting element 7 on the lifting platform 6 detects the load, and the corresponding task information is transmitted to the lifting platform 6. The supporting plate 62 of the lifting platform 6 can form a support for 3 beams at the bottom of the Chinese character 'Chuan' shaped tray, so that the tray 8 is prevented from turning sideways. At the same time, the second weight detecting element 7 of the elevating table 6 detects the tray 8. After the lifting platform 6 is lifted up, the warehouse-in task information is transmitted to the lifting platform 6, and the stacker is applied to pick up goods. After the stacker is operated to the picking position, the fork starts to extend to take away the tray 8 of the lifting table 6. After the pallet 8 is removed by waiting for the stacker forks to extend, the lift table 6 is lowered back again to the lowered position and relevant information is cleared.

The warehouse-out process comprises the steps that the lifting table 6 is automatically lifted to a high position to wait for the stacker to put goods, the stacker takes a plate of tray 8 from the high-frame warehouse and puts the plate of tray 8 on the lifting table 6, the second weight detection element 7 of the lifting table 6 detects the tray 8, task information is generated and then starts to descend, the first weight detection element 5 of the transplanting conveying device detects the tray 8 after the lifting table is lowered to a low position, the task information is transmitted to the conveying chain 2, and the conveying chain 2 starts to reversely rotate to convey the tray 8 to a forklift taking and putting platform. When the pallet 8 reaches the picking station, the first weight detecting element 5 is activated and the task information is transferred to the picking station. After the forklift recognizes that the pallet 8 is in place and stops conveying, the pallet 8 on the platform is forked away, and the warehouse-out task flow is finished.

Fig. 4 is a schematic structural diagram of a transplanting and conveying device in which a field-shaped tray is placed, and fig. 5 is a schematic structural diagram of a lifting platform in which a field-shaped tray is placed. The field-shaped pallet warehousing and ex-warehouse processes are the same as the Chuan-shaped pallet warehousing and ex-warehouse processes, and are not repeated here.

The transplanting conveying device provided by the technical scheme can be simultaneously suitable for the Chinese character 'Chuan' type tray and the Chinese character 'Tian' type tray, all processes are automatically completed, the operation of manually replacing the tray 8 is not needed, and the warehouse moving operation efficiency is greatly improved.
