Wooden pallet conveyor

Abstract

The wooden pallet conveying device provided by the present invention controls the movement of the iron slide plate through the conveying line, so that the iron slide plate and the wooden pallet corresponding to the current coiled material move to the stacking station together. When the iron slide plate and the wooden pallet enter the stacking station, the centering device first detects the position of the iron slide plate and the wooden pallet, so that the coiled material packaging control system automatically calculates the placement error of the iron slide plate in the front and rear directions, so that the iron slide plate drives the wooden pallet to stay accurately at the stacking station, and finally the wooden pallet is pushed by the centering device to further correct the left and right placement of the wooden pallet, further ensuring that the wooden pallet is centered at the stacking station.

Description

Technical Field

[0001] The invention relates to the technical field of suspended film roll packaging, and in particular to a wooden pallet conveying device. Background Art

[0002] The coil is a cylindrical roll of plastic film. After the coil is produced, it needs to be transported to various places for sale. In order to protect the integrity of the coil during transportation, reduce wear and tear, and increase the transportation quantity, the coil needs to be suspended packaged. Suspended packaging can be understood as first independently packaging a single coil, the surface of the coil is covered with bubble film, and then the paper cover and foam pad are buckled at both ends and fixed with tape; then vertical plywood and plugs are installed at both ends of the coil, and then the two vertical plywood are bundled so that the coil is suspended between the two vertical plywood. After the suspension packaging is completed, the film roll needs to be moved from the bundling station to the stacking station. A wooden pallet is placed on the stacking station, and several film rolls are stacked on the wooden pallet so that the forklift can realize transportation and shipment.

[0003] Since there are many types of coils, each type of suspended packaging coil needs to be carried by a specific wooden pallet. After the suspended packaging coils are bundled and packaged, they will be flipped over by a handling robot and placed on a wooden pallet. If the position of the wooden pallet deviates, it will affect the placement and stacking of the suspended packaging coils.

DETAILED DESCRIPTION

[0030] The present invention provides a wooden pallet conveying device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0031] In this article, “before” means Figure 1 The direction indicated by the middle arrow is also one of the conveying directions of the wooden pallet, and "front" and "back" are opposite.

[0032] See also Figure 1-Figure 10 The present invention provides a wooden pallet conveying device, comprising a conveyor line 1 extending in a front-to-rear direction, a plurality of iron slides 214 arranged on the conveyor line 1, a stacking station 5 is arranged in the middle of the conveyor line 1, and a wooden pallet 3 is placed on each iron slide 214. The conveyor line 1 can transport the iron slides 214 and the wooden pallets 3 on the iron slides 214 to the stacking station 5. A centering component for centering the wooden pallet 3 is arranged next to the stacking station 5. The centering component and the conveyor line 1 are both controlled by a coil packaging control system.

[0033] The centering assembly includes two groups of wooden pallet 3 position detection devices and iron slide plate 214 stroke detection devices, and two push plate assemblies 43 arranged between the two groups of iron slide plate 214 stroke detection devices, and the two push plate assemblies 43 are arranged symmetrically on the left and right; one group of wooden pallet 3 position detection devices and iron slide plate 214 stroke detection devices are arranged at the front end of the stacking station 5, and the other group of wooden pallet 3 position detection devices and iron slide plate 214 stroke detection devices are arranged at the rear end of the stacking station 5. The wooden pallet 3 position detection devices, iron slide plate 214 stroke detection devices and push plate assemblies 43 are all electrically connected to the coil packaging control system. Before stacking, the wooden pallet 3 to be transported may be in front of or behind the stacking station 5. No matter whether the wooden pallet 3 enters the stacking station 5 from the front of the stacking station 5 or from the rear of the stacking station 5, the wooden pallet 3 position detection devices and iron slide plate 214 stroke detection devices are used to detect the stroke of the wooden pallet 3 and the iron slide plate 214 to ensure that the wooden pallet 3 is accurately moved to the stacking station 5.

[0034] The wooden pallet conveying device provided by the present invention controls the movement of the iron slide plate 214 through the conveying line 1, so that the iron slide plate 214 and the wooden pallet 3 corresponding to the current coil are moved to the stacking station 5 together. When the iron slide plate 214 and the wooden pallet 3 enter the stacking station 5, the travel detection device of the iron slide plate 214 detects the moving distance of the front end of the iron slide plate 214, and the trigger timing of the front end surface of the wooden pallet 3 is detected by the position detection device of the wooden pallet 3, so that the coil packaging control system automatically calculates the placement error of the iron slide plate 214 in the front and rear directions, so that the iron slide plate 214 drives the wooden pallet 3 to stay accurately at the stacking station 5, and the wooden pallet 3 is pushed synchronously by the two pushing plate assemblies 43, so as to further correct the left and right placement of the wooden pallet 3, and ensure that the wooden pallet 3 is accurately moved to the preset stacking station 5.

[0035] In the non-stacking state, all the iron slides 214 are away from the stacking station 5, that is, the stacking station 5 does not have an iron slide 214 and a wooden pallet 3. In this embodiment, four iron slides 214 are provided, each of which is numbered, and a numbered iron slide 214 corresponds to a wooden pallet of a specific model. When it is found that a certain numbered iron slide 214 does not have a wooden pallet, the staff immediately places the wooden pallet 3 of the corresponding model on the numbered iron slide 214, that is, before stacking, each numbered iron slide 214 is manually placed with a wooden pallet 3 of the corresponding model. The coil packaging control system can obtain the coil model to be stacked according to the upstream equipment located in the wooden pallet conveying device, and then obtain the iron slide 214 and wooden pallet that need to be transported to the stacking station 5. It can be understood that since the wooden pallet 3 is manually placed on the iron slide 214, the wooden pallet 3 is not accurately positioned at this time, and it is impossible to determine whether the wooden pallet 3 is placed in the center, so there will generally be a placement error.

[0036] When considering the placement position of the wooden pallet in the front-rear direction, the following three situations will occur: First, set the length of the iron slide plate 214 as \(a\) mm. If the wooden pallet 3 is just placed in the middle of the iron slide plate 214 without any placement error, the position of the front end face of the wooden pallet 3 is the standard position at this time, and the distance between the front end face of the wooden pallet 3 and the front edge of the iron slide plate 214 is \(s\) mm. The iron slide plate 214 carries the wooden pallet 3 and moves towards the palletizing station 5. When the iron slide plate 214 travel detection device senses the front end of the iron slide plate 214, the iron slide plate 214 travel detection device feeds back a signal to the coil packaging control system, records it as the first point, and the iron slide plate 214 travel detection device starts to monitor the moving stroke of the iron slide plate 214 in real time. As the iron slide plate 214 continues to move forward, the wooden pallet 3 position detection device senses the front end face of the wooden pallet 3 and feeds back a signal to the coil packaging control system, records it as the second point, and the coil packaging control system immediately obtains the moving stroke \(\Delta b1\) of the iron slide plate 214 during the time from the first point to the second point.

[0037] (1) If \(\Delta b1 = s\) mm, it means that the wooden pallet 3 has no placement error. After the palletizing conveyor line 1 drives the iron slide plate 214 to move another \((a - \Delta b1)\) mm, the wooden pallet 3 can accurately stop at the palletizing station 5. That is, when the iron slide plate 214 travel detection device monitors the moving stroke \(\Delta b2\) of the iron slide plate 214 from the first point to the current point, and when \(\Delta b2 = a\) mm, a signal is fed back to the coil packaging control system, and the coil packaging control system controls the palletizing conveyor line 1 to stop moving.

[0038] (2) If \(\Delta b1 < s\) mm, it means that the wooden pallet 3 is shifted forward after being placed on the iron slide plate 214. At this time, the position of the front end face of the wooden pallet 3 is in front of the standard position. After the palletizing conveyor line 1 drives the iron slide plate 214 to move another \([(a - s) - (s - \Delta b1)]\) mm, the wooden pallet 3 can accurately stop at the palletizing station 5 to make up for the placement error. That is, when the iron slide plate 214 travel detection device monitors the moving stroke \(\Delta b2\) of the iron slide plate 214 from the first point to the current point, and when \(\Delta b2 = (a - s + \Delta b1)\) mm, a signal is fed back to the coil packaging control system, and the coil packaging control system controls the palletizing conveyor line 1 to stop moving.

[0039] (3) If \(\Delta b1 > s\) mm, it means that the wooden pallet 3 is shifted backward after being placed on the iron slide plate 214. At this time, the position of the front end face of the wooden pallet 3 is behind the standard position. After the palletizing conveyor line 1 drives the iron slide plate 214 to move another \([(a - s) + (s - \Delta b1)]\) mm, the wooden pallet 3 can accurately stop at the palletizing station 5 to make up for the placement error. That is, when the iron slide plate 214 travel detection device monitors the moving stroke \(\Delta b2\) of the iron slide plate 214 from the first point to the current point, and when \(\Delta b2 = (a + s - \Delta b1)\) mm, a signal is fed back to the coil packaging control system, and the coil packaging control system controls the palletizing conveyor line 1 to stop moving.

[0040] After the iron slide 214 transports the wooden pallet 3 to the stacking station 5, the coil packaging control system controls the two push plate assemblies 43 to push the wooden pallet 3 synchronously, so that the wooden pallet 3 is centered between the two push plate assemblies 43, and the deviation of the wooden pallet 3 in the left and right directions is corrected. The position of the wooden pallet 3 after positioning is the same as the preset placement setting, which assists the upstream handling equipment to accurately place the suspended packaging film roll on the wooden pallet 3, and then the stacking fixing placement robot installs the stacking fixing on the top of the vertical clamping plate of the suspended packaging film roll, so that the two suspended packaging film rolls can be stacked stably.

[0041] Specifically, the travel detection device of the iron slide plate 214 includes a first bracket 421, a touch pressure detection head 422 arranged above the first bracket 421, and an elastic push rod 4232 assembly 423 arranged on the top of the first bracket 421; the elastic push rod 4232 assembly 423 is used to push the touch pressure detection head 422 to touch the iron slide plate 214. Under normal conditions, the elastic push rod 4232 assembly 423 provides elastic thrust for the touch pressure detection head 422, so that the touch pressure detection head 422 extends and waits for the iron slide plate 214 to trigger. When the front end of the iron slide plate 214 passes the touch pressure detection head 422, the front end of the iron slide plate 214 pushes the touch pressure detection head 422 to retract, thereby triggering the touch pressure detection head 422. Under the action of the elastic push rod 4232 assembly 423, the touch pressure detection head 422 always presses against the side of the iron slide plate 214 and monitors the moving stroke of the iron slide plate 214 in real time as the iron slide plate 214 moves.

[0042] Further, the touch pressure detection head 422 includes a push wheel 4222 bracket 4221, a push wheel 4222, and a rotary encoder 4223 arranged above the push wheel 4222. The axis of the push wheel 4222 is arranged vertically and is rotatably connected to the push wheel 4222 bracket 4221 through a rotating shaft, and the rotary encoder 4223 is connected to the rotating shaft on the push wheel 4222. The push wheel 4222 is pressed against the side of the iron slide 214 by the elastic push rod 4232 assembly 423, and under the action of friction, the push wheel 4222 rotates with the movement of the iron slide 214. Since the rotating shaft rotates synchronously with the push wheel 4222, the rotary encoder 4223 can detect the angular displacement variable of the rotating shaft and the push wheel 4222, so that the coil packaging control system can calculate the rotation amount of the push wheel 4222 according to the circumference of the push wheel 4222, and the rotation amount of the push wheel 4222 is the travel distance of the iron slide 214.

[0043] Specifically, the elastic push rod 4232 assembly 423 includes a hollow sleeve 4231, a push rod 4232 passing through the inner cavity of the sleeve 4231, and a spring 4234 sleeved on the push rod 4232. The sleeve 4231 is provided with a stopper 4235 at one end facing the push wheel 4222 bracket 4221. One end of the push rod 4232 is fixedly connected to the push wheel 4222 bracket 4221, and the other end is provided with a limit head 4236 for limiting the push rod 4232 from being separated from the sleeve 4231. The spring 4234 is located between the stopper 4235 and the push wheel 4222 bracket 4221. Through such a configuration, the push wheel 4222 can, on the one hand, be compressed by the spring 4234 to buffer the movement impact of the iron slide 214, and on the other hand, the elastic force of the spring 4234 can ensure that the push wheel 4222 is always pressed against the side of the iron slide 214, thereby ensuring the effectiveness of the stroke detection of the iron slide 214.

[0044] Preferably, the wooden pallet 3 position detection device includes a group of through-beam sensors, and the transmitter 411 and the receiver 412 of the through-beam sensor are respectively arranged on the left and right sides of the palletizing station 5. The transmitter 411 emits infrared light to the receiver 412, and when the infrared light is blocked by the wooden pallet 3, it means that the through-beam sensor detects the front end surface of the wooden pallet 3.

[0045] The push plate assembly 43 includes a second bracket 431, a slide 432 slidably disposed on the bracket, a push plate 433 fixed on the slide 432, and a cylinder 434 for driving the slide 432 to reciprocate left and right, and the push plate 433 extends in the horizontal direction. The cylinders 434 on the two push plate assemblies 43 move synchronously, and the two cylinders 434 drive the corresponding push plates 433 to move toward the center of the stacking station 5. The two push plates 433 push toward the side of the wooden pallet 3 to correct the deviation of the wooden pallet 3 in the left and right directions.

[0046] Preferably, a guide rail (not visible in the figure) extending in the left-right direction is provided on the second bracket 431, and the bottom of the slide 432 is slidably connected to the guide rail through a slider. By providing the guide rail and the slider, the moving direction of the push plate 433 is ensured to be accurate, smooth and reliable.

[0047] The conveyor line 1 is formed by connecting multiple transport components 10, each of which includes a base frame 11, multiple groups of transmission components 12 arranged on the base frame 11 and arranged along the conveying direction, a driving component 13 drivingly connected to one of the transmission components 12, and an iron slide 214 placed on the transmission component 12; two adjacent transmission components 12 are connected in transmission, and the transmission component 12 is used to support and drive the iron slide 214 to move forward and backward.

[0048] Each group of the transmission components 12 includes a first support wheel 121 and a second support wheel 122 rotatably arranged on one side of the base frame 11, and a third support wheel 123 and a fourth support wheel 124 rotatably arranged on the other side of the base frame 11. The axes of the first support wheel 121, the second support wheel 122, the third support wheel 123 and the fourth support wheel 124 all extend left and right. The first support wheel 121 and the third support wheel 123 are coaxially arranged and connected by a first transmission shaft 125. The second support wheel 122 and the fourth support wheel 124 are coaxially arranged and connected by a second transmission shaft 126. The first transmission shaft 125 and the second transmission shaft 126 are connected by a first transmission component 15, and two adjacent transmission components 12 are connected by a second transmission component 16. The first transmission component 15 and the second transmission component 16 can specifically adopt transmission methods such as chain transmission and synchronous belt transmission.

[0049] Specifically, the iron slide plate 214 includes a horizontally arranged panel body 141 and two L-shaped legs 142 symmetrically arranged on both sides of the panel body 141. The panel body 141 and the L-shaped legs 142 are integrally formed, and the iron slide plate 214 has good supporting capacity. A wooden pallet 3 will be placed on the upper surface of the iron slide plate 214, and then several suspended packaged film rolls will be stacked on the wooden pallet 3, and finally the wooden pallet 3 and the film rolls will be moved away from the iron slide plate 214 by a forklift.

[0050] Both ends of the first supporting wheel 121, the second supporting wheel 122, the third supporting wheel 123 and the fourth supporting wheel 124 are arranged on the bottom frame 11 through the bearing seat 17. The first supporting wheel 121 and the second supporting wheel 122 are rollers with two convex rings 1211, and the third supporting wheel 123 and the fourth supporting wheel 124 are flat rollers. One of the L-shaped legs 142 of the iron slide 214 is inserted between the two convex rings 1211, so that the iron slide 214 cannot move left and right, thereby positioning the L-shaped legs 142 of the iron slide 214, and improving the moving stability of the iron slide 214. Of course, the third supporting wheel 123 and the fourth supporting wheel 124 can also be rollers with two convex rings 1211.

[0051] Specifically, the driving assembly 13 includes a double-headed reducer 131 fixed on the base frame 11, a driving motor 132 connected to the double-headed reducer 131, and the transmission assembly 12 connected to the double-headed reducer 131 does not need to be provided with a first transmission shaft 125. The double-headed reducer 131 is arranged between the first supporting wheel 121 and the third supporting wheel 123. One end of the double-headed reducer 131 is connected to the first supporting wheel 121 through a coupling 133 and a third transmission shaft 134, and the other end of the double-headed reducer 131 is connected to the third supporting wheel 123 through a coupling 133 and a third transmission shaft 134. The third transmission shaft 134 connected to the first supporting wheel 121 is connected to the second transmission shaft 126 located in front of it through the first transmission assembly 15. That is, the driving motor 132 drives the first supporting wheel 121 and the third supporting wheel 123 to rotate synchronously through the double-headed reducer 131, and under the drive of the first transmission assembly 15 and the second transmission shaft 126, the second supporting wheel 122 and the fourth supporting wheel 124 are driven to rotate synchronously, thereby driving all the transmission assemblies 12 to rotate synchronously. The driving motor 132 adjusts the forward and reverse power output to make the transmission assembly 12 move forward and reverse, thereby driving the iron slide plate 214 forward or backward.

[0052] In order to better support the iron slide 214 and make the iron slide 214 move more smoothly, at least one auxiliary roller 18 is provided between the first roller 121 and the second roller 122 of each group of the conveying components 12, and at least one auxiliary roller 18 is provided between the third roller 123 and the fourth roller 124 of each group of the conveying components 12.

[0053] Preferably, a cover plate 111 for capping the driving assembly, the first transmission assembly 15 and the second transmission assembly 16 is provided on the base frame 11. The cover plate 111 can reduce the dust and foreign matter from contaminating the first transmission assembly 15 and the second transmission assembly 16 to cause abnormal noise and jamming, thereby ensuring the smooth movement of the first transmission assembly 15 and the second transmission assembly 16.
