Description

Technical Field

[0001] The invention relates to a clothes hanger releasing mechanism for a hanging conveyor line. Background Art

[0002] At present, the hangers used in the intelligent hanging line are all operated by the hanger rollers rolling on the track. Although the transportation efficiency of this operation method of the hangers is relatively low, the hangers need to wait for processing before arriving at the processing position, so there is no excessive requirement for the transportation efficiency of the hangers on the intelligent hanging line. Patent No. ZL2009201198584, the utility model patent named "Smart Clothing Production Hanging System Hanger Release Control Mechanism" provides a smart clothing production hanging system hanger release control mechanism, including a release limit block, a rotating mechanism, a bracket and a rotating shaft. The release limit block is connected to the rotating mechanism, and the rotating mechanism is connected to the bracket through the rotating shaft. The release limit block is driven to rotate by the rotating mechanism to realize the release and blocking of the hanger. This patent is applied to the release control of roller hangers. The spacing between adjacent hanger rollers is large, and the release speed of the release control mechanism can meet the requirements.

[0003] However, when the hanging conveyor line is used for intelligent sorting or automated warehousing, the sorting speed of a sorting point reaches 150 to 200 hangers per minute, which puts high demands on the conveying speed of the hangers. Therefore, the structure of the hanger on the hanging conveyor line removes the hanger rollers of the traditional intelligent hanging line, and directly adopts the method of hanging the hanger hook on the slide rail, or adding a carrier between the hanger and the slide rail, the carrier hook is hung on the slide rail, and the hanger hook is hung on the carrier. In this way, when used for warehousing, the hangers can be arranged very closely, which greatly increases the storage quantity in the warehouse area. When used for sorting lines, the distance of the sorting gap is reduced, and the stroke of the control cylinder is reduced to meet the sorting system's requirements for sorting speed. However, this increases the difficulty of individual release control of the hanger hook or the carrier hook, and the technical solution provided by the above-mentioned utility model patent cannot be applied to this situation. How to solve this problem has become a topic that must be overcome in the entire system design process. Summary of the invention

[0004] The invention provides a clothes hanger releasing mechanism for a hanging conveyor line, which can realize the release of clothes hangers one by one and has high action reliability.

[0005] The hanger releasing mechanism of the hanging conveyor line provided by the present invention comprises a bracket and a driving assembly, wherein a rear hook is installed on the bracket and the rear hook can rotate around a mounting point under the drive of the driving assembly, and a rear stop hook of the rear hook is adapted to the hanger hook; the mechanism also comprises a front hook, the rear end of the front hook is installed on the bracket, and the front end of the front hook is connected to the rear hook through a pin, and a avoidance hole is provided at the front end of the front hook, and a rotating shaft of the rear hook is connected to the bracket after passing through the avoidance hole, and when the rear hook rotates, the front hook is moved by the pin to rotate around its mounting point on the bracket, and the rotation direction of the front hook is opposite to that of the rear hook; the front stop hook of the front hook is adapted to the hanger hook. The rear hook is initially in a blocking state, the rear blocking hook blocks the hanger, the front hook is retracted, and the front blocking hook does not contact the hanger. When it is necessary to release, the driving assembly drives the rear hook to rotate, and the rear blocking hook is disengaged from the hanger hook. At the same time, during the rotation of the rear hook, the pin drives the front hook to rotate, and the front hook rotates and moves downward, and the front blocking hook is inserted between the first hanger hook and the second hanger hook, so that the first hanger is released and the second hanger is blocked, realizing the release of hangers one by one. The front blocking hook also adopts an eagle's beak shape, which is easy to insert and block, and has high action reliability. Since the front hook and the rear hook move in opposite directions at the same time, the avoidance hole is set to avoid interference between the two movements. The shape of the avoidance hole is an arc-shaped waist-shaped hole with the installation point of the front hook on the bracket as the center of the circle.

[0006] Since the front hook is driven to rotate by the rear hook, from a mechanical point of view, the driving force required for the rear hook to drive the front hook is reduced. From the rear end to the front end of the front hook, there are the front hook shaft hole, the push pin installation point, and the avoidance hole. When designing, the push pin installation point of the front hook is kept as far away from the rear hook shaft hole as possible. In this way, the front hook can obtain a larger driving torque under the action of the same driving force.

[0007] Preferably, the front hook is provided with a shifting hole in a transverse waist shape, and the shifting pin is movably installed in the shifting hole, so that when the rear hook drives the front hook, the shifting pin has a certain amount of movement margin to avoid motion interference between the rear hook and the front hook, causing malfunctions.

[0008] Since the diameter of the hanger hook may be different, in order to adapt to hooks of different diameters while ensuring the release effect and release efficiency, when the distance between the front hook shaft hole and the pin installation point on the front hook is certain, the distance between the pin installation point on the rear hook and the shaft installation point of the rear hook is adjusted according to the size of the hanger hook. When the hanger hook diameter is large, the distance between the two is increased, and the rotation amplitude of the rear hook becomes larger. When the hanger hook diameter is small, the distance between the two is reduced, and the rotation amplitude of the rear hook becomes smaller. Of course, the distance between the front hook shaft hole and the pin installation point on the front hook can also be changed according to actual conditions to achieve the same effect, but this distance should not be too small, otherwise the front hook stopper hook will not be easy to insert between the two carrier hooks during release. In theory, this distance should be increased as much as possible when the structure is possible to obtain the best release control effect.

[0009] The hanger release mechanism of the hanging conveyor line provided by the present invention can reliably realize the short-distance release control of the hanger hooks one by one by arranging the front hook and the rear hook. The present invention uses the driving component to control the rotation of the rear hook, and the front hook and the rear hook are linked by a mechanical mechanism. Even if the distance between adjacent hanger hooks is very close or even close together, the present invention can realize the release of only one hanger at a time, and the release control is accurate and reliable. Since the diameter of the hanger hook is small, the stroke of the driving component is reduced, and the release efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] Embodiment 1:

[0019] like Figure 4 , 5 As shown in Figures 1 and 7, the hanger release mechanism includes a bracket 1, a driving assembly 2, and a rear hook 4. The driving assembly 2 is mounted on the bracket 1, and the driving assembly 2 can use a driving cylinder; the rear hook 4 is rotatably mounted on the bracket 1, and a driving hole 4-1 is provided on the rear hook 4. The rear hook 4 is connected to the driving assembly 2 through the driving hole 4-1. The rear stop hook of the rear hook is adapted to the carrier hook 7, and can be in an eagle beak shape to facilitate hooking the carrier hook 7. The hanger release mechanism is mounted above the slide rail 5, and the slide rail 5 is tilted, and the bracket 1 is also tilted at a corresponding angle.

[0020] In the initial state, the drive assembly 2 makes the rear hook 4 in the clockwise limit position, and the rear stop hook 4-4 on the rear hook 4 blocks the carrier hook 7. Under the control of the controller, the hanger release mechanism drives the assembly 2 to work, so that the rear hook rotates counterclockwise to the limit position, so that the rear stop hook on the rear hook is gradually separated from the carrier hook 7 until it is completely separated, and the carrier 6 slides downward under the action of gravity, realizing the batch release of the carrier. The hanger release mechanism is controlled by the controller, the drive assembly is reset, the hanger release mechanism returns to the starting position, and the rear hook is in the clockwise limit position. The above process completes a carrier release cycle and waits for the start of the next cycle.

[0021] Embodiment 2:

[0022] like Figure 1 , 2 As shown in Figures 3, 6 and 7, the hanger release mechanism includes a bracket 1, a driving assembly 2, a front hook 3 and a rear hook 4. The driving assembly 2 is installed on the bracket 1, and the driving assembly 2 can use a driving cylinder. The hanger release mechanism is installed above the slide rail 5, the slide rail 5 is tilted, and the bracket 1 is also tilted at a corresponding angle. The rear end of the front hook 3 (the left end in the figure) is provided with a front hook shaft hole 3-1, and a horizontal waist-shaped front hook shifting hole 3-3 and a vertical arc waist-shaped (arc waist-shaped with the front hook shaft hole 3-1 as the center) avoidance hole 3-2 are sequentially arranged to the right. The front end of the front hook 3 also has a front stopper hook 3-4, and the front stopper hook 3-4 is compatible with the carrier hook and can be in an eagle's beak shape. The rear hook 4 is provided with a driving hole 4-1, a rear hook shifting hole 4-3, and a rear hook shaft hole 4-2. The rear hook 4 has a rear stopper hook 4-4, and the rear stopper hook 4-4 is compatible with the carrier hook and can be in an eagle's beak shape. The front hook 3 is installed on the bracket 1 through the front hook shaft hole 3-1, and the rear hook 4 is installed on the bracket 1 through the rear hook shaft hole 4-2, wherein the shaft of the rear hook 4 passes through the avoidance hole 3-2 and then is connected to the bracket, and the pin 8 passes through the front hook shifting hole 3-3 and the rear hook shifting hole 4-3 and then is fixed on the rear hook.

[0023] The working process of the hanger release mechanism of the hanging conveyor line is as follows:

[0024] Initial position: Figure 1 As shown, the driving assembly 2 makes the rear hook 4 in the clockwise limit position, and the rear blocking hook 4-4 on the rear hook 4 blocks the vehicle hook 7. The front hook 3 is in the counterclockwise limit position under the action of the detent pin 8 and is in a separated state from the vehicle hook 7.

[0025] 1. The hanger release mechanism is controlled by the controller, and the drive assembly 2 works. The drive assembly 2 makes the rear hook 4 rotate counterclockwise to the limit position, and the rear stop hook 4-4 on the rear hook 4 is gradually separated from the carrier hook 7 until it is completely separated, and the carrier 6 slides downward under the action of gravity. Figure 2 shown.

[0026] 2. At the same time, the rear hook 4 moves the front hook hole 3-3 through the pin 8 to make the front hook 3 rotate clockwise to the limit position, and the front blocking hook 3-4 on the front hook 3 is inserted between the vehicle hooks 7 of the vehicle following the vehicle to be released, blocking the vehicle hooks. Figure 2 shown.

[0027] 3. If Figure 3 As shown, the hanger release mechanism is controlled by the controller, the drive assembly 2 is reset, and the hanger release mechanism returns to the initial position.

[0028] The above process completes a vehicle release cycle and waits for the start of the next cycle.

[0029] Since the diameter of the hanger hook may be different, in order to adapt to hooks of different diameters while ensuring the release effect and release efficiency, when the distance between the front hook shaft hole and the pin installation point on the front hook (front hook pull hole 3-3) is certain, the release effect can be controlled to the best by adjusting the distance between the rear hook shaft hole 4-2 and the rear hook pull hole 4-3. When the diameter of the hanger hook is large, the distance between the two is increased, and the rotation amplitude of the rear hook becomes larger. When the diameter of the hanger hook is small, the distance between the two is reduced, and the rotation amplitude of the rear hook becomes smaller. Of course, the distance between the front hook shaft hole 3-1 and the pin installation point on the front hook (front hook pull hole 3-3) can also be changed according to actual conditions to achieve the same effect, but this distance should not be too small, otherwise the front hook stopper hook will not be easily inserted between the two carrier hooks during release. In theory, this distance is increased as much as possible when the structure is possible to obtain the best release control effect.
