Abstract
Description
Technical Field
[0001] The utility model relates to the field of palletizers, in particular to a cantilever palletizer. Background Art
[0002] After some plates are processed, they need to be stacked and palletized. Generally, they are stacked by manual handling or using a palletizer. The current palletizer generally includes a base and a horizontal swing arm installed on the base that can move linearly, and a vertical swing arm is installed at the end of the horizontal swing arm. The vertical swing arm is a cylinder and a clamp is also connected to the bottom of the vertical swing arm. The clamp is connected to the telescopic rod of the cylinder. By adjusting the telescopic activity of the telescopic rod of the cylinder, the clamp can be moved in the vertical direction, and then the plates below can be grabbed and palletized. The overall height of the cylinder is fixed and cannot be adjusted in position. When palletizing needs to grab the workpiece at a lower position, the length of the entire cylinder also needs to be lengthened accordingly to match the height of the overall base. This makes the entire height of the palletizer higher, and the height space requirements are higher, which is not suitable for use in some low-height spaces. For this reason, we designed a cantilever palletizer. Utility Model Content
[0003] In order to solve the technical problem that the length of the cylinder needs to be lengthened when performing grabbing operations at a lower position, the entire height of the entire palletizer is relatively high, resulting in a high requirement for height space, the utility model provides a cantilever palletizer.
[0004] The utility model is implemented by the following technical scheme: a cantilever palletizer comprises a base, two symmetrically arranged frames are vertically installed on the front and rear sides above the base, a mounting plate is arranged between the two frames, a lifting mechanism is installed on the right surface of the mounting plate in an up-and-down lifting manner, and a telescopic mechanism is installed on both the front and rear ends of the lifting mechanism for sliding left and right, the telescopic mechanism comprises a transversely arranged telescopic arm, a longitudinal frame is installed below between the rightmost ends of the two telescopic arms, a plurality of equally spaced transverse frames are arranged below the longitudinal frame, and a plurality of evenly distributed suction cups are installed below the transverse frame.
[0005] As a further improvement of the above scheme, the lifting mechanism includes a longitudinally arranged lifting plate, and laterally distributed extension plates are installed at both front and rear ends of the right side surface of the lifting plate. Two guide frames are symmetrically arranged at the upper and lower ends of the outward side of the two extension plates, and a transverse slider is installed on the inward side of the guide frame. Transverse tracks are arranged on the upper and lower side surfaces of the telescopic arm, and the transverse tracks are slidably connected to the transverse slider to facilitate the telescopic arm to move left and right in a straight line along the transverse slider. The design of the transverse track and the transverse slider reduces overall wear, facilitates movement, and improves movement accuracy, making it less likely to shift its position.

The vertical sliders are slidably connected to the vertical tracks to facilitate the lift to move up and down along the racks. The maximum stroke of the lifting mechanism is slightly smaller than the height of the entire equipment, and it can be lowered to the minimum height, so that panels at any height position can be grabbed.
[0007] As a further improvement of the above scheme, a telescopic motor is installed on the left surface of the lifting platform, the output shaft of the telescopic motor is connected to a transmission box 1, and telescopic shafts are rotatably installed between the front and rear ends of the transmission box 1 and the two extension plates, the outward end of the telescopic shaft is placed outside the extension plate and is installed with a driving gear, and a moving rack is provided on the inward surface of the telescopic arm, and the moving rack is meshed with the driving gear for transmission. The telescopic motor can rotate the telescopic shaft through the transmission box 1, and then transmit the driving gears at both ends. The rotating driving gear can move the moving rack to the left or right, so as to facilitate the change of the position of the telescopic arm, thereby moving the panel from one place to another and stacking it neatly.
[0008] As a further improvement of the above solution, a vacuum pump is installed above the two extension plates through a longitudinal rod and a mounting plate, and the air inlet end of the vacuum pump is connected to the suction cup through a hose to facilitate the suction cup to absorb and grab the plate.
[0009] As a further improvement of the above scheme, a lifting motor is installed above the left surface of the mounting plate, and a transmission box 2 is installed on the output shaft of the lifting motor, and a lifting shaft is rotatably installed between the front and rear ends of the transmission box 2 and the two frames through bearings, and a transmission sprocket is installed at the outward end of the two lifting shafts, and guide sprockets are rotatably installed on the left and right sides of the outward ends of the two frames through bearings and shaft rods, and a lifting chain is installed on the guide sprocket and the transmission sprocket, the right end of the lifting chain is connected to the upper end of the lifting plate, and the other end of the lifting chain is connected to a counterweight block, and the lifting motor can rotate the transmission sprockets at the front and rear ends through the transmission box 2, thereby changing the length of the lifting chains at the left and right ends, so that the lifting mechanism can be lifted and lowered as needed, and one end of the lifting chain is connected to the lifting mechanism, and the other end is connected to the counterweight block, which can offset the increase in lifting torque caused by the length of the lifting chain, thereby reducing the load of the lifting motor.

[0023] The lifting mechanism 4 includes a longitudinally arranged lifting plate 41, and transversely distributed extension plates 42 are installed at both ends of the front and rear ends of the right side surface of the lifting plate 41. Two guide frames 43 are symmetrically arranged at the upper and lower ends of the two extension plates 42 facing outward, and a transverse slider 44 is installed on the inner side of the guide frame 43. Transverse rails 32 are arranged on the upper and lower side surfaces of the telescopic arm 31. The transverse rails 32 are slidably connected with the transverse slider 44 to facilitate the telescopic arm 31 to move left and right in a straight line along the transverse slider 44. The design of the transverse rails 32 and the transverse slider 44 reduces overall wear, facilitates movement, and improves movement accuracy, making it less likely to shift its position.
[0024] A vertical rail 21 is installed on the right side surface of the two racks 2, and two vertical sliders are symmetrically arranged at the front and rear ends of the left side surface of the lifting plate 41. The vertical sliders are slidably connected to the vertical rail 21 to facilitate the lifting mechanism 4 to move up and down along the rack 2. The maximum stroke of the lifting mechanism 4 is slightly smaller than the height of the entire equipment, and it can be lowered to the lowest height, and can grab panels at any height position.
[0025] A telescopic motor 45 is installed on the left side surface of the lifting plate 41, and the output shaft of the telescopic motor 45 is connected to a transmission box 46, and a telescopic shaft 47 is rotatably installed between the front and rear ends of the transmission box 46 and the two extension plates 42.

The rotating driving gear can make the moving rack 33 move to the left or right, so as to facilitate the change of the position of the telescopic arm 31, thereby moving the panels from one place to another and stacking them neatly.
[0026] A vacuum pump 6 is installed above the two extension plates 42 through a longitudinal rod and a mounting plate. The air inlet end of the vacuum pump 6 is connected to the suction cup 81 through a hose, so that the suction cup 81 can absorb and grab the plate.
[0027] A lifting motor 51 is installed above the left surface of the mounting plate 22, and a transmission box 2 is installed on the output shaft of the lifting motor 51.

When working, the lifting motor 51 rotates forward to move the lifting mechanism 4 downward, so that multiple suction cups 81 can be placed on the upper surface of the plate below, and then the vacuum pump 6 can make the suction cup 81 firmly fix the plate, and the lifting motor 51 rotates in the opposite direction, the counterweight block 9 moves downward, and the lifting mechanism 4 moves upward, so that the plate moves upward as a whole, and then the telescopic motor 45 rotates forward and makes the two telescopic arms 31 move to the right at the same time, so that the plate is in the desired placement position, and this can be repeated to stack multiple plates together;
[0029] By fixing the suction cup 81 below the telescopic arm 31, and the telescopic arm 31 is arranged on the lifting mechanism 4, the lifting mechanism 4 is moved up and down by the lifting motor 51, the lifting chain 5, and the counterweight 9, so that the maximum stroke of the lifting mechanism 4 is slightly less than the height of the entire device, and it can be lowered to the lowest height, and the plate at any height position can be grabbed, so that multiple plates can be quickly stacked;
