Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of container displacement technology, and more particularly to a container displacement mechanism for changing the orientation of a garbage container. Background Art
[0002] Containers, such as trash compactors, often have end caps at their ends. This allows them to be horizontal and closed during transport, and vertical and open during collection. A container tilting mechanism is a commonly used device for changing the container's orientation, switching it between horizontal and vertical positions. Existing container tilting mechanisms are designed to grab the container from above, then lift and tilt it. However, container transfer machinery, such as boom trucks, used to transport containers often also need to grab the container from above. Therefore, due to interference from the tilting mechanism, the container transfer machinery cannot place the container directly below it. The existing solution is to set up a temporary transition area. The container transfer machinery first places the container in the transition area and drives away from the transition area. The tilting mechanism then moves to the transition area and grabs the container. Therefore, existing container tilting mechanisms cannot directly cooperate with the container transfer machinery, complicating the container transfer process and increasing the transfer site's footprint.
[0003] Therefore, in this field, there is an urgent need for a device that can directly cooperate with a garbage container transfer vehicle such as a hook truck. Summary of the Invention

[0021] Further features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings. Exemplary embodiments of the present invention are shown in the accompanying drawings, and the various drawings are not necessarily drawn to actual scale. However, the present invention may be implemented in many different forms and should not be construed as necessarily being limited to the exemplary embodiments disclosed herein. On the contrary, these exemplary embodiments are merely provided to illustrate the present invention and to convey the spirit and essence of the present invention to those skilled in the art.
[0022] The present invention is directed to an improved container positioning mechanism that can reliably secure and reposition containers, such as waste compactors, to switch them between transport and collection positions. The mechanism also efficiently cooperates with a waste compactor grabbing and transporting platform, such as a trolley, thereby reducing the space required to transfer containers between the trolley and the positioning mechanism. Specifically, the container positioning mechanism according to the present invention allows a trolley to directly transfer containers to and from the positioning mechanism, eliminating the need for a temporary transition area to transfer containers between the trolley and the positioning mechanism, as is required for existing positioning mechanisms that grab containers from above. Therefore, compared to existing positioning mechanisms, the container positioning mechanism according to the present invention not only reliably changes the position of waste compactors but also significantly reduces the floor space required during operation by eliminating the transition area.
[0023] The following describes in detail, with reference to the accompanying drawings, alternative but non-limiting embodiments of the container displacement mechanism according to the present invention. In the drawings, the vertical direction is indicated by arrow VV', the longitudinal direction (also referred to as the fore-aft direction) is indicated by arrow LL', and the transverse direction is indicated by arrow TT'. The longitudinal direction LL' and the transverse direction TT' can be considered to be directions defined in a horizontal plane. It should be noted that the aforementioned directional terms used herein are intended solely to more intuitively describe the relative orientations of various components in conjunction with the accompanying drawings and should not be construed in any way as limiting the scope of protection of the present invention.
[0024] refer to Figure 1 , which shows a schematic perspective view of a container shifting mechanism according to the present invention, wherein no container is assembled on the container shifting mechanism. Figure 1As shown, the container positioning mechanism 100 includes a fixed frame 110. The fixed frame 110 can be fixed to a floor or other platform, for example, by welding, riveting, or bolting to an underground steel frame. This allows the fixed frame 110 to remain stationary during operation of the container positioning mechanism 100, thereby providing support for other components and the container. A pair of rotating arms 121, 122 are spaced apart from each other along a transverse direction TT' and are rotatably connected to the fixed frame 110, enabling rotation relative to the fixed frame 110 about a common rotation axis XX'. Therefore, the transverse direction TT' can also be referred to as an axial direction. A pair of connecting arms 131, 132 are fixed to the rotating arms 121, 122, respectively, by welding, riveting, or bolting. Therefore, the connecting arms 131, 132 are also spaced apart from each other along the transverse direction TT', thereby forming a container-receiving space between the rotating arms 121, 131 and the rotating arms 122, 132. The suspension frame 140 is fixed to the pair of connecting arms 131, 132 and is positioned between the pair of connecting arms 131, 132. Therefore, the suspension frame 140 is also positioned between the pair of rotating arms 121, 122. In particular, the connecting arms 131, 132 extend in a direction different from that of the rotating arms 121, 122 (for example, in a direction transverse to the rotating arms 121, 122), thereby spacing the suspension frame 140 from the rotating arms 121, 122. In this configuration, the above-mentioned accommodation space will extend through between the rotating arms 121, 122 in a direction away from the suspension frame 140 (at Figure 1 In the orientation shown, the container extends upwards), so that the container can enter and exit the storage space between the rotating arms 121 and 122, which enables the arm truck to pass through between the rotating arms 121 and 122 to put the container into the storage space or take the container out of the storage space. In other words, an opening is defined between the rotating arms 121 and 122, through which the container can enter and exit the storage space. In addition, the storage space also extends in the extension direction of the suspension frame 140 (in the direction of the extension direction of the suspension frame 140). Figure 1 In the orientation shown, it extends in the longitudinal direction LL'), which allows the container to move in the accommodation space along the extension direction of the suspension frame 140, but the accommodation space is in a direction transverse to the rotating arms 121, 122 (in the direction of the Figure 1 In the orientation shown, the vertical direction (VV′) ends at the suspension rack 140 , which allows a container entering the accommodation space to stop at and rest against the suspension rack 140 .
[0025] In particular, a pair of driving devices 151, 152 are disposed between the pair of rotating arms 121, 122 and the fixed frame 110. Of course, only one driving device may be disposed between one of the rotating arms 121, 122 and the fixed frame 110. When activated, the driving devices 151, 152 can drive the rotating arms 121, 122, the connecting arms 131, 132 fixed to the rotating arms 121, 122, and the suspension frame 140 to rotate relative to the fixed frame 110. The driving devices 151, 152 can be composed of power mechanisms such as hydraulic cylinders and motors.
[0026] refer to Figure 2 , which shows a schematic partial cross-sectional view of a container shifting mechanism according to the present invention and a container assembled thereto. Figure 2 As shown, when the container 200 is assembled on the container shifting mechanism 100 , the container 200 enters the accommodation space defined between the rotating arm 121 and the connecting arm 131 and the rotating arm 122 and the connecting arm 132 as described above, and is supported on the suspension frame 140 .
[0027] Back to Figure 1 The suspension frame 140 may include a support bar 141 for abutting against the container 200 (specifically, the base 210 of the container 200) and a locking device 142 (such as Figure 1 (As shown in the partial enlarged figure in the figure). Figure 1In the illustrated orientation, the support bar 141 extends along the longitudinal direction LL′ and has a flat upper surface to allow the container 200 to translate thereon, for example, to allow rollers provided on the base 210 of the container 200 to roll thereon. Thus, the upper surface of the support bar 141 constitutes an engagement surface of the suspension frame 140 for engaging with the container. A locking device 142 can lock the container 200 so that the container 200 is held against the support bar 141. Specifically, the locking device 142 includes a telescopic pin 143 that can extend from and retract into the suspension frame 140, and a swivel head 144 that is rotatably disposed on the telescopic pin 143 (e.g., disposed at the end of the telescopic pin 143). During use, when the container 200 abuts against the support bar 141, the telescopic pin 143 can be extended from the suspension frame 140 and inserted into the hole in the base 210 of the container. The rotating head 144 then rotates relative to the telescopic pin 143, thereby preventing the telescopic pin 143 from being disengaged from the hole in the base 210 of the container. In this way, the container 200 can be locked on the suspension frame 140 and kept against the support bar 141. When it is necessary to move the container 200, the rotating head 144 can be first rotated back to its original position, and then the telescopic pin 143 can be retracted into the suspension frame 140. That is, the locking device 142 is adapted to switch between two states, namely a locked state and an unlocked state. In the locked state, the telescopic pin 142 extends from the suspension frame 140 and the rotating head 144 rotates to a position where its side edge is not aligned with the side edge of the telescopic pin 143; in the unlocked state, the telescopic pin 142 retracts into the suspension frame 140 and the rotating head 144 rotates to a position where its side edge is aligned with the side edge of the telescopic pin 143. The locking device 142 can switch between the locked state and the unlocked state by the linear motion (also referred to as telescopic motion) of the telescopic pin 143 and the rotational motion of the rotating head 144. In particular, the suspension frame 140 may include a plurality of support bars 141 and a plurality of locking devices 142, for example, Figure 1 1 shows two support bars 141 and two locking devices 142 spaced apart along the transverse direction TT' (in other words, in a direction parallel to the rotation axis XX'), thereby more reliably fixing and supporting the container 200. In particular, the support bars 141 may be provided with a stopper 148, which is used to position the container 200. For example, when the rollers on the base 210 of the container 200 abut against the stopper 148, the telescopic pin 143 can be aligned and accurately inserted into the hole in the base 210 of the container.
[0028] like Figure 1 and Figure 2As shown, the suspension frame 140 may further include a limiting device 145, which is configured to limit (i.e., prevent) the container 200 from moving in a direction transverse to the extension direction of the support bar 141. In particular, the limiting device 145 includes a pair of limiting blocks 146 separated along the transverse direction TT' (i.e., the direction transverse to the extension direction of the support bar 141), and the pair of limiting blocks 146 can move toward each other so as to enter corresponding grooves 211 (e.g., grooves 211) provided in the base 210 of the container 200. Figure 2 Since the extension direction of the groove 211 is parallel to the extension direction of the support bar 141 and is open toward the transverse direction TT', after the limiting block 146 enters the groove 211 (i.e., reaches the limiting state), the container 200 can be moved along the extension direction of the support bar 141 ( Figure 1 The pair of limit blocks 146 can move in the longitudinal direction LL' of the support bar 141, but cannot move in a direction transverse to the extension direction of the support bar 141. Of course, the pair of limit blocks 146 can also move away from each other so as to present a released state out of the corresponding groove 211, thereby releasing the container 200. In particular, each limit block 146 can abut against the upper side wall 212 or the lower side wall 213 of the groove 211 in a limited state (for example, through rollers), thereby preventing the container 200 from shaking. In addition, if the limit block 146 is provided with a roller, the sliding friction between the limit block 146 and the groove 211 can be converted into rolling friction between the roller and the groove 211. Of course, the suspension frame 140 can also include a plurality of limit devices 145 to more reliably limit the movement of the container 200.
[0029] like Figure 1 and Figure 2 As shown, the suspension frame 140 may further include an auxiliary support device 147, which is spaced apart from the support bar 141 along the transverse direction TT' (i.e., a direction parallel to the rotation axis XX') and is configured to support the container 200 together with the support bar 141. Specifically, the support bar 141 is used to support rollers provided at the front of the base 210 of the container 200, while the auxiliary support device 147 is used to support the rear of the base 210 of the container 200. In particular, when the stop block 146 is in the restricted state, the stop block 146 abuts against the lower sidewall 213 of the groove 211, while the auxiliary support device 147 supports the base 210 of the container 200. In this configuration, the stop block 146 and the auxiliary support device 147 together clamp the base 210 of the container 200, thereby more reliably positioning the container 200. In particular, the auxiliary supporting device 147 may also be provided with rollers for abutting against the base 210 of the container 200 so as to replace sliding friction with rolling friction.
[0030] As described above, the suspension frame 140 can reliably hold the container 200 through the holding devices such as the support bar 141, the locking device 142, the limiting device 145, and the auxiliary supporting device 147. Therefore, when the rotating arms 121 and 122 drive the suspension frame 140 to rotate through the connecting arms 131 and 132, the suspension frame 140 can reliably drive the container 200 to rotate together, for example, Figure 2 and Figure 3 The container 200 is rotated to a substantially horizontal position as shown. Figure 4 and Figure 5 The container 200 is shown in a generally vertical position. Figure 2 and Figure 3 In the position shown, the hooklift can pass the container 200 between the rotating arms 121 and 122 and place it on the suspension frame 140. Then, the container 200 can be securely held by the holding devices on the suspension frame 140. At this time, these holding devices are docked with the base 210 of the container 200 on the upper side of the suspension frame 140. Conversely, the holding devices can be released to allow the container 200 to be separated from the suspension frame 140, and then the container 200 can be passed between the rotating arms 121 and 122 and removed from the suspension frame 140. Figure 2 and Figure 3 The position shown can be referred to as the docking state or docking position of the suspension frame 140. It is worth mentioning that in the docking state, the suspension frame 140 makes the joint plane (for example, composed of the upper surface of the support bar 141) substantially horizontal, and the suspension frame 140 is located at the bottom of the container displacement mechanism 100 so that the joint plane faces upward, and the arm truck used to transfer the container can directly place the container on the suspension frame 140, or directly remove the container on the suspension frame 140 without setting up a transition area for temporarily storing containers, which reduces the requirements of the container transfer on the work site and simplifies the operational process of the container transfer. In addition, in the docking state, the rotating arms 121, 122 and the connecting arms 131, 132 are all located above the suspension frame 140, so they can play a role in guiding the container onto the suspension frame 140 or guiding the container away from the suspension frame 140. Figure 4 and Figure 5 In the illustrated position, the container 200 is substantially vertical. The end cover 220 of the container 200 can be opened to allow items to be placed (e.g., garbage, cargo, etc.) into the container 200. This position allows the container to function as a collection device, which can be referred to as the enabled state or enabled position of the suspension 140. In this enabled state, the suspension 140 positions the joint plane substantially vertically. It is worth noting that, although the above description describes the suspension 140 positions the joint plane substantially horizontally and substantially vertically, the suspension 140 can obviously be positioned in other positions to position the joint plane in a different orientation, such as an inclined orientation.
[0031] like Figure 4 and Figure 5 As shown, the suspension frame 140 generally includes two parts, namely, a support frame 140' fixed to the connecting arms 131, 132 and a sliding frame 140" slidably attached to the support frame 140', wherein the support frame 140' is used to support the container 200, and the sliding frame 140" is used to lock the container 200 and drive the container 200 to slide relative to the support frame 140', so that the sliding of the sliding frame 140" relative to the support frame 140' is associated with the sliding of the container along the engagement plane. To this end, support bars 141, limiting devices 145, auxiliary supporting devices 147, which support the container and allow the container to move relative thereto, are provided on the support frame 140', while locking devices 142, which lock the container and prevent the container from moving relative thereto, are provided on the sliding frame 140". As shown in FIG. Figure 4 and Figure 5 It can be seen that when the suspension frame 140 rotates to Figure 4 After the enabled state shown, the sliding frame 140" drives the container to slide down to Figure 5 The weighing state or weighing position shown. One or more pressure sensors 111 can be provided on the fixed frame 110, so that when the sliding frame 140″ is in the weighing state, the container 200 will be supported on the pressure sensor 111. In particular, the hole in the base 210 of the container 200 for receiving the locking device 142 can be an elongated hole, so that the sliding frame 140″ can continue to slide downward for a certain distance after the container 200 contacts the pressure sensor 111. In other words, in the weighing state, the sliding frame 140″ does not apply a vertical force to the container 200, so that the container 200 falls freely onto the weighing sensor 111, thereby enabling the pressure sensor 111 to more accurately detect the weight of the container 200.
[0032] like Figure 5 As shown, the sliding frame 140" is arranged at one end of the support frame 140', and the support bar 141 extends outward from the same end of the support frame 140', and the distance that the support bar 141 extends from the support frame 140' is greater than the stroke of the sliding frame 140", so that no matter how the sliding frame 140" moves, the support bar 141 and the engaging plane located thereon (more specifically, the support bar 141 and the portion of the engaging plane extending from the support frame 140') remain between the sliding frame 140" and the container 200, so that the engaging plane can more reliably support the container and more reliably guide the sliding of the container.
[0033] like Figure 4 and Figure 5As shown, one or both of the connecting arms 131, 132 may be provided with a cover opening device 133, which can, for example, engage the end cover 210 of the container 200 when the suspension frame 140 is in an enabled state (more particularly, when the sliding frame 140" is in a weighing state) and can open and close the end cover 220. In particular, the cover opening device 133 includes a pivot arm 134 rotatably provided on the corresponding connecting arm 131, 132, a latch 135 telescopically provided on the pivot arm 134, and a latch 135 which is provided on the hinged end of the container 200. A drive device 136 is configured to drive the pivot arm 134 to rotate. In use, the latch 135 can be inserted into a corresponding hole in the end cover 220, thereby coupling the end cover 220 to the pivot arm 134. The drive device 136 can then drive the pivot arm 134 to rotate, and the pivot arm 134 will drive the end cover 220 to rotate via the latch 135, so as to open and close the end cover 220. After closing the end cover 220, the latch 135 can be disengaged from the end cover 220, thereby decoupling the end cover 220 from the pivot arm 134.
[0034] In use, the suspension frame 140 of the container displacement mechanism 100 is first in Figure 1-3 The container 200 is in a substantially horizontal docking state as shown. At this time, the hooklift can place the container 200 on the suspension frame 140 and move the container 200 along the support bar 141 until the rollers on the base 210 of the container 200 abut against the block 148. Then, the locking device 142 can be used to lock the container 200, and the limit device 145 can be used to limit the movement of the container 200. After the container 200 is securely held on the suspension frame 140 by these holding devices, the driving devices 151 and 152 are used to drive the rotating arms 121 and 122 to rotate until the suspension frame 140 is in the horizontal position. Figure 4-5 As shown, the container 200 is in a substantially vertical enabling state, and then the sliding frame 140" is used to drive the container 200 downward until the container 200 is in a weighing state in which it freely falls on the weighing sensor 111. After that, the end cover 210 of the container 200 is opened by the cover opening device 133 to enable the container 200 to receive items. After the container 200 is full (or reaches a predetermined weight), the above operations are performed in reverse order until the arm truck removes the container 200 on the suspension frame 140 in the docking state.
[0035] The above describes in detail, with the aid of the accompanying drawings, an optional but non-limiting embodiment of a container displacement mechanism according to the present invention. It will be apparent to those skilled in the art that modifications and additions to the techniques and structures, as well as recombinations of features in the various embodiments, without departing from the spirit and substance of this disclosure, are all within the scope of the present invention. Therefore, all such modifications and additions that are conceivable under the teachings of this invention are considered part of this invention. The scope of this invention includes both known equivalent technologies as of the filing date of this application and unforeseen equivalent technologies.
