Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tools for gas meter production, specifically relating to a batch transport tray for meter housings. Background Technology

[0002] The meter housing is one of the important components of a diaphragm gas meter. It is usually produced by stamping. The gas meter movement and the meter housing have sealing surfaces. After the main body is formed, a sealing strip is installed on the inside of the meter housing to further improve the sealing performance of the diaphragm cavity.

[0003] In the processing of metering shells, pallet loading and transportation are usually used. During the application process, the applicant found that traditional pallets are not conducive to stacking. That is, it is not easy to align the top and bottom when stacking, or it is easy to tilt and jam when taking them out. In addition, traditional pallets are not conducive to automated robotic arms to grasp and place, and are difficult to adapt to automated production lines. Utility Model Content

[0004] In view of this, the present invention provides a batch transport pallet for gas meter housings to solve the problems of inconvenience in stacking and picking up gas meter housings on pallets in the prior art, which is not conducive to automatic grasping.

[0005] The technical solution is as follows:

[0006] A batch transport pallet for metering shells includes a plate-shaped body with a plurality of spaced placement holes that are adapted to the recesses of the metering shells. The key feature is that the bottom of the plate-shaped body has at least three evenly distributed support columns, the height of which is greater than or equal to the depth of the recesses of the metering shells, and the outer edge of the bottom of the plate-shaped body is stepped inward.

[0007] The above solution, with its stepped bottom structure, facilitates rapid stacking and support, prevents misalignment, and makes removal easier. It also prevents or avoids situations where the upper and lower parts cannot be removed due to jamming. On the other hand, the support columns prevent the metering shells in the upper and lower trays from contacting each other, leaving sufficient space to avoid affecting the quality of adhesive application.

[0008] Preferably, the plate-shaped main body is rectangular, with an inwardly tapering ridge along its outer edge at the bottom. Each of the four corners of the plate-shaped main body has a positioning piece, located inside the inwardly tapering ridge, and its height is greater than or equal to the height of the support column. With this design, a first positioning step is formed between the inwardly tapering ridge and the plate-shaped main body, and a second positioning step is formed between the positioning piece and the inwardly tapering ridge. The two positioning steps work together to ensure the stability of the pallets during stacking. During stacking, the first positioning step of the upper pallet is supported on the flange of the lower pallet, while the positioning piece mainly serves to guide the pallet in, making it easier to stack them sequentially.

[0009] Preferably, the positioning piece is located at the corner of the plate-shaped main body and is horizontally arranged in an L-shape. This design achieves better positioning results without requiring a large volume.

[0010] To facilitate handling, the flange has opposing hand grips at both ends along its length.

[0011] Preferably, the flange has at least two sets of symmetrically arranged clamping openings on both sides along its length. This design facilitates direct lateral gripping and improves its adaptability.

[0012] Preferably, the plate-shaped main body has opposing positioning bosses on both sides of its top length, and a positioning groove at the bottom of the plate-shaped main body corresponding to the positioning bosses. With this design, during stacking, the positioning groove of the upper pallet engages with the positioning boss of the lower pallet, which helps to further improve stacking stability.

[0013] Preferably, the clamping openings are symmetrically arranged on both sides of the positioning boss. This design improves the stability of the clamping movement.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The metering shell batch transport pallet provided by this utility model facilitates stacking, quick removal, and mechanical gripping, while improving stacking stability and protection, and reducing the impact on products. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] refer to Figures 1 to 7 The batch transport pallet for metering shells shown mainly includes a plate-shaped body 610. The outer edge of the plate-shaped body 610 has an upwardly bent flange 620 along its thickness direction. The plate-shaped body 610 has a plurality of spaced placement holes 611, which allow the metering shells to be placed with their concave surfaces facing upwards. The outer edge of the metering shells is supported on the plate-shaped body 610. The bottom of the plate-shaped body 610 has at least three evenly distributed support pillars 612. The height of the support pillars 612 is greater than or equal to the depth of the concave portion of the metering shell. This ensures that when two pallets 600 are stacked, the metering shells in the upper pallet will not contact the metering shells in the lower pallet.

[0025] Furthermore, to further improve the stability of pallet stacking, the bottom outer edge of the plate-shaped body 610 has an overall inward-curving stepped structure. Specifically, the bottom of the plate-shaped body 610 has an inward-curving ridge 650 along its outer edge. The inward-curving ridge 650 is located inside the flange 620 above the plate-shaped body 610, forming a first positioning step between the inward-curving ridge 650 and the plate-shaped body 610. At the same time, the four corners of the plate-shaped body 610 have generally L-shaped positioning pieces 614. The positioning pieces 614 are located inside the inward-curving ridge 650, forming a second positioning step between them. The two positioning steps work together to fully ensure the stability of pallet stacking. In addition, the corners of the plate-shaped body 610, flange 620, inward-curving ridge 650, and positioning pieces 614 are all rounded. The stepped positioning structure also facilitates the quick alignment and stacking of pallets, as well as the removal of the upper pallet, improving ease of use.

[0026] In this embodiment, the plate-shaped main body 610 is generally rectangular plate-shaped structure, with hand grips 613 at both ends in the length direction, and at least two sets of clamping openings 621 symmetrically arranged in the width direction on the flange 620.

[0027] The tray 600 has a positioning boss 630 symmetrically arranged along its length near the center. The bottom of the tray has a positioning groove 640 corresponding to the positioning boss 630. When the upper and lower trays 600 are stacked, the positioning boss 630 of the lower tray is just inserted into the positioning groove 640 of the upper tray. In specific implementation, there are two sets of clamping ports 621, which are symmetrically arranged on both sides of the positioning boss 630.

[0028] refer to Figures 1 to 7The batch transport pallet for metering shells shown is used in the gluing production line for metering shell processing. As shown in the figure, it includes a pallet supply unit 400 and a pallet transfer unit 500. The pallet supply unit 400 mainly includes an empty pallet stacking station 410, a pallet transfer line 420 and an empty pallet gripper assembly 430 corresponding to the empty pallet stacking station. The pallet transfer line 420 includes at least a pallet placement position and a pallet waiting position. The empty pallet gripper assembly 430 can grab the empty pallets in the empty pallet stacking station 410, place them in the pallet placement position, and transport them to the pallet waiting position.

[0029] The pallet transfer unit 500 mainly includes a pallet fixing station and a full-load pallet stacking station 540, as well as a pallet fixing component 510 and a metering shell gripper assembly (not shown) corresponding to the pallet fixing station, and a full-load pallet gripper assembly 530 for gripping and placing the pallet at the pallet fixing station to the full-load pallet stacking station, wherein the metering shell gripper assembly is used to grip and place the metering shell A, which has been glued on the glue applicator, into the pallet at the pallet fixing station.

[0030] Specifically, the pallet supply unit 400 and the pallet transfer unit 500 share a main frame beam structure, which is mainly composed of columns, beams and protective grilles. The pallet supply unit 400 includes a frame B440 fixed on the main frame. The frame B440 includes two horizontally aligned main beams 441 and multiple secondary beams 442 connecting the two main beams 441. The pallet transfer line 420 is fixed on the frame B440 and located between the two main beams 441. It includes two horizontally parallel straight belts. The main beams 441 have guide beams 444. The inner side of the guide beams 444 has vertically arranged rollers 443. The vertical distance between the two horizontally aligned rollers 443 is adapted to the width of the pallet.

[0031] The pallet fixing station is located above the pallet waiting area. The pallet fixing assembly 510 mainly includes two positioning cylinders 511 arranged opposite each other around the pallet fixing station, and a lifting cylinder 512 arranged below the pallet transfer line 420, as shown in the figure. The piston rods of the positioning cylinders 511 are all horizontally inward, and their ends are provided with abutment plates 513. The lifting cylinders 512 are fixed on the sub-beam 442, with their piston rods facing upward, and have horizontally arranged lifting positioning plates 514. Typically, the bottom of the pallet has reinforcing ribs, and the lifting positioning plate 514 has positioning grooves 5130 that are adapted to the position of the reinforcing ribs, ensuring that the position of the pallet in the width direction is not affected by the horizontal force after the pallet is lifted. Position 514 is located between two straight conveyor belts. During operation, when the pallet reaches this position (i.e., the pallet waiting position, detected by a positioning sensor), the pallet transfer line 420 stops working. The lifting cylinder 512 lifts the lifting positioning plate 514, simultaneously raising the pallet on the straight conveyor belt until it aligns with the position of the clamping plate 513. Then, the positioning cylinder 511 activates, fixing the pallet in place (in the pallet fixed position) via the clamping plate 513. In this embodiment, the end face of the clamping plate 513 abuts against the side of the pallet's inward-facing protrusion 650, while its upper surface contacts the plate-shaped body 610, providing support and ensuring the stability of the pallet's posture. Then, the lifting cylinder 512 resets, the lifting positioning plate 514 falls, and the pallet transfer line 420 resumes operation, transporting the pallet from the pallet placement position to the pallet waiting position, keeping one pallet in a waiting state, which helps improve production efficiency.

[0032] The fully loaded pallet gripper assembly 530 mainly includes a gripper base C531 and a gripper drive mechanism C for driving the gripper base C531 to move up and down and horizontally. The gripper base C531 includes a connecting beam C5310 and multiple gripper mounting beams C5311, as shown in the figure. The gripper mounting beams C5311 and the connecting beams C5310 are all horizontally arranged and perpendicular to each other. Gripper assemblies C are installed at both ends of the gripper mounting beams C5311. The gripper assembly C mainly includes a clamping cylinder 5312. The piston rod of the clamping cylinder 5312 faces... In addition, a clamping plate 5313 is connected, as shown in the figure. In this embodiment, the position of the gripper mounting beam C5311 is adapted to the position of the positioning groove 640 and the clamping opening 621 on the pallet. It should be noted that the inner side of the clamping plate 5313 corresponding to the clamping opening 621 has a clamping groove 5314, while the clamping plate 5313 corresponding to the positioning groove 640 only has an inwardly horizontally bent part at the bottom. In this way, when the fully loaded pallet gripper assembly 530 is working, the pallet can cooperate well with it, greatly improving the clamping stability effect.

[0033] During the production process, empty pallets are stacked at the empty pallet stacking station 410. The pallet gripper assembly 430 can then grab and place them onto the pallet transfer line 420. The pallet transfer line 420 will then send them to the pallet waiting position, or even further to the pallet fixing position, where they will be fixed by the pallet fixing component 510. Then, the metering shell gripper assembly can grab and place the metering shells that have been coated with glue into the pallet. When the pallet is full, the full-load pallet gripper assembly 530 can then transfer the entire pallet with the metering shells to the full-load pallet stacking station 540 for transport to the next production process.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
