[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0036] Embodiment 1
[0037] See also Figures 1 to 4 The present embodiment provides a barrel mouth correcting device for correcting the barrel mouth 910 of the packaging barrel 900 to a preset position. The barrel mouth correcting device includes: a first lifting actuator 100, a barrel mouth correcting mechanism 200, a base 300, a top surface barrel pressing mechanism 400, a barrel blocking mechanism 600, a barrel pushing mechanism 700 and a detection device 800.
[0038] The first lifting actuator 100 is installed through a stand 110 arranged next to the base 300. In this embodiment, a cylinder is used as the first lifting actuator 100. The cylinder body of the cylinder is vertically installed on the stand 110, and the piston rod of the cylinder extends and retracts up and down in the vertical direction.
[0039] The barrel mouth correcting mechanism 200 is connected to the piston rod of the above-mentioned cylinder, and the up and down telescopic movement of the piston rod of the above-mentioned cylinder can drive the barrel mouth correcting mechanism 200 to move up and down; the barrel mouth correcting mechanism 200 has a pair of barrel mouth conformable clamps 210 that can be controlled to open and clamp by pneumatic fingers 220, and the pneumatic fingers 220 adopt parallel pneumatic fingers, which are connected to the piston rod of the above-mentioned cylinder. The ends of the barrel mouth conformable clamps 210 are provided with clamping parts 211 that are arranged in accordance with the outer contour shape of the raised part of the barrel mouth 910 of the packaging barrel 900. When a pair of the barrel mouth conformable clamps 210 are clamped, the clamping parts 211 at the ends of the barrel mouth conformable clamps 210 can clamp the raised part of the barrel mouth 910, and the clamping process is the correcting process of the barrel mouth 910. After the clamping is completed, the barrel mouth 910 is corrected to the preset position.
[0040] The base 300 is used to carry the packaging barrel 900. The top surface of the base 300 is provided with four rollers 310 spaced apart along the circumferential direction of the packaging barrel 900. The rollers 310 can rotate about an axis that is radially the same as the packaging barrel 900. When the packaging barrel 900 rotates on the base 300, the bottom surface of the packaging barrel 900 contacts the rollers 310. The rotation of the rollers 310 can reduce the friction at the bottom of the packaging barrel 900, making the rotation of the packaging barrel 900 smoother.
[0041] The top surface barrel pressing mechanism 400 is disposed above the base 300 , and includes a second lifting actuator 410 , a rotating shaft 420 connected to the second lifting actuator 410 , and a barrel pressing roller 430 disposed at the end of the rotating shaft 420 .
[0042] In this embodiment, a cylinder is used as the second lifting actuator 410. The cylinder is installed above the base 300 through a bracket. The cylinder body of the cylinder is vertically arranged, and the piston rod of the cylinder is extended and retracted up and down in the vertical direction. The rotating shaft 420 is connected to the piston rod of the above-mentioned cylinder, and can be lifted and lowered under the drive of the above-mentioned cylinder. The rotating shaft 420 is arranged along the radial direction of the packaging barrel 900, and the barrel pressing roller 430 can rotate with the rotating shaft 420 as the axis. In the initial state, the distance between the barrel pressing roller 430 and the base 300 can ensure that the packaging barrel 900 passes through.
[0043] After the packaging barrel 900 is conveyed to the base 300, the second lifting actuator 410 drives the rotating shaft 420 to descend, so that the barrel pressing roller 430 is pressed on the top edge of the packaging barrel 900, which can prevent the packaging barrel 900 from tilting, moving, etc. during rotation. In this embodiment, the barrel pressing roller 430 is made of non-metallic materials such as rubber to avoid damage to the packaging barrel 900 when pressing down.
[0044] The barrel blocking mechanism 600 is disposed on one side of the base 300 , and the packaging barrel 900 enters the base 300 from a side opposite to the barrel blocking mechanism 600 .
[0045] The barrel-stopping mechanism 600 includes a third lifting actuator 610 and a barrel-stopping member 620; a cylinder is used as the third lifting actuator 610, and the cylinder body of the cylinder is vertically installed on one side of the base 300, and the piston rod of the cylinder is extended and retracted up and down in the vertical direction; the barrel-stopping member 620 is connected to the piston rod of the above-mentioned cylinder, and can move up and down under the drive of the above-mentioned cylinder. When the barrel-stopping member 620 descends, the height of its highest point is lower than the height of the upper surface of the base 300. When the barrel-stopping member 620 rises, the height of its highest point is higher than the height of the upper surface of the base 300, so as to block the packaging barrel 900 entering the base 300.
[0046] The barrel pushing mechanism 700 has two, and the two barrel pushing mechanisms 700 are symmetrically arranged on the other two sides of the base 300. The barrel pushing mechanism 700 includes a telescopic actuator 710 and a barrel pushing member 720. A cylinder is used as the telescopic actuator 710, and the cylinder body of the cylinder is horizontally installed on the side of the base 300, and the piston rod of the cylinder telescopes and moves in the horizontal direction. The barrel pushing member 720 is connected to the piston rod of the above-mentioned cylinder and can telescope and move horizontally under the drive of the above-mentioned cylinder. When the packaging barrel 900 enters the base 300 and is blocked by the barrel blocking member 620, the two telescopic actuators 710 drive the two barrel pushing members 720 to extend relative to each other to position the packaging barrel 900.
[0047] The detection device 800 includes a first sensor 810, a second sensor 820, a third sensor 830 and a sensing plate 840: the first sensor 810 is installed on the stand 110 through a bracket, and is used to detect the height position signal of the pneumatic finger 220; the second sensor 820 is also installed on the stand 110 through a bracket, and is used to detect the position signal of the pneumatic finger 220 clamping the finger. When the second sensor 820 detects the signal of the pneumatic finger 220 clamping the finger, it indicates that the pneumatic finger 220 is in an open state, that is, a pair of the barrel mouth conformable clamps 210 are in an open state; the third sensor 830 is installed on one of the barrel mouth conformable clamps 210, and the sensing plate 840 is installed on the other barrel mouth conformable clamp 210. When the third sensor 830 detects the sensing plate 840, it indicates that a pair of the barrel mouth conformable clamps 210 are in a clamped state.
[0048] The general working process of the barrel mouth correction device provided in this embodiment is as follows:
[0049] The packaging barrel 900 enters from one side of the base 300 and is blocked by the barrel blocking member 620. The two telescopic actuators 710 drive the two barrel pushing members 720 to extend relative to each other to position the packaging barrel 900. When the packaging barrel 900 is positioned correctly on the base 300, the second lifting actuator 410 drives the rotating shaft 420 to descend, so that the barrel pressing roller 430 at the end of the rotating shaft 420 is pressed on the top edge of the packaging barrel 900. At the same time, the first lifting actuator 410 drives the rotating shaft 420 to descend, so that the barrel pressing roller 430 at the end of the rotating shaft 420 is pressed on the top edge of the packaging barrel 900. The component 100 drives the barrel mouth correcting mechanism 200 to move downward. After the barrel mouth correcting mechanism 200 is lowered into place, the pneumatic finger 220 controls the barrel mouth conformable clamp 210 to clamp, and the clamping portion 211 at the end of the barrel mouth conformable clamp 210 clamps the raised portion of the barrel mouth 910 of the packaging barrel 900; if the position of the barrel mouth 910 of the packaging barrel 900 is offset, during the clamping process, the packaging barrel 900 will follow the rotation, and finally the barrel mouth 910 of the packaging barrel 900 will be corrected to the preset position.

In order to avoid the situation where the barrel mouth 910 cannot be corrected due to insufficient clamping force of the pneumatic fingers 220, the present embodiment is provided with an auxiliary clamping mechanism 500 to assist the pneumatic fingers 220 in clamping the barrel mouth conformable clamp 210.
[0052] The auxiliary clamping mechanism 500 includes two auxiliary clamping cylinders 510 connected to the first lifting actuator 100. The two auxiliary clamping cylinders 510 are horizontally arranged on both sides of a pair of barrel mouth conformable clamps 210. The extension and retraction direction of the piston rod of the auxiliary clamping cylinder 510 intersects with the length direction of the barrel mouth conformable clamps 210. The end of the piston rod of the auxiliary clamping cylinder 510 is provided with a top piece 520. When the piston rod of the auxiliary clamping cylinder 510 is extended, the top piece 520 contacts the barrel mouth conformable clamp 210, thereby providing clamping force for the barrel mouth conformable clamp 210.
