Description

  The present invention relates to a distribution shelf device, and more particularly to a distribution shelf device for an operator to take out a boxed electrical component or the like and perform a predetermined operation.

  2. Description of the Related Art Conventionally, as a distribution shelf device, an assembly operator takes out an object to be transported such as packed electrical parts from a box, and the empty box after the parts are taken out is transported to a predetermined place using gravity. There exists an apparatus (refer patent document 1). In this conventional shelf apparatus, a supply shelf that is inclined downward toward the operator, a discharge shelf that is inclined downward toward the discharge side, and a switching shelf that is provided so as to be capable of reciprocating rotation along the inclination of both shelves. It has. In this physical distribution shelf device, the boxes are supplied and transported to the switching shelf in a state in which the switching shelf is in a posture along the inclination of the supply shelf, and the empty box after the operator has taken out the electrical parts etc. It is sent to the discharge shelf from the switching shelf rotated so as to follow the inclination.

  In such a shelf device, normally, the next box is sequentially placed on the supply shelf during the work of taking out the electrical components etc. from the box that has been transported to the switching shelf. It is necessary to stop the box placed on the shelf from moving to the switching shelf side. For this reason, in the said shelf apparatus, the stopper is provided in the load conveyance surface of a supply shelf in the middle of a supply shelf so that withdrawal is possible, and this stopper is withdrawn according to the timing of an operation | work. In order to control the timing of the stopper exit / exit, a detector for detecting the arrival of the box, a cylinder device that is driven in accordance with a signal from the detector, or that stops driving are provided.

Japanese Utility Model Publication No. 7-23713

  Certainly, according to the above-described conventional distribution shelf device, the boxes sequentially conveyed from the supply shelf can be moved to the switching shelf with good timing. However, in the above conventional shelf device, an electrically operated means such as a detector is used to move the stopper away. Normally, in this type of shelf device, it is necessary to move and relocate appropriately according to the work content and the situation at the work site (product assembly line), etc., so electricity is supplied to each place where the shelf device is moved. Such special equipment becomes essential. In addition, this necessitates the handling of electrical wiring, which hinders work, and ultimately limits the degree of freedom of shelf device layout in the factory.

  Further, according to the above conventional distribution shelf device, the stopper for temporarily stopping the box conveyed from the supply shelf is composed of a protruding piece whose front end protrudes upward from below the conveying surface. However, when the weight of the box is heavy or when the speed at which the box is transported is high, the box may move over the stopper and flow downward.

  The present invention has been made in order to overcome the above-described problems, and does not require special electrical equipment, and can appropriately stop a transported object transported from upstream. An object is to provide a shelf device.

In order to solve the above problems, a distribution shelf device according to the present invention includes a transport shelf body, an upstream transport shelf provided in the transport shelf body, and a downstream transport shelf provided in the transport shelf body. A transfer shelf for transporting a transported object transported from the upstream transport shelf to the downstream transport shelf and a transported object transported from the upstream transport shelf are temporarily locked. And a stopper that prevents movement to the switching shelf, and the switching shelf is rotatably attached to the transport shelf body via a shelf support shaft, and accepts an object to be transported from the upstream transport shelf. And a transport posture for transporting the object to be transported to the downstream transport shelf by the switching means, and the stopper is disposed on the downstream side of the upstream transport shelf, A horizontal bar provided across the transfer surface above the transfer surface. Comprising a stopper body having, the stopper body has a locked state for preventing movement of the switching shelves engaged with the carried object conveyed from the upstream transport rack to release the locking state The switching means can be switched to the unlocked state in which the conveyed object is moved to the switching shelf, and the switching means rotates the switching shelf without using a power source that operates by electric power. And moving the stopper main body up and down by transmitting the movement of the switching shelf and moving the stopper main body up and down. And switching between .

  According to the physical distribution shelf device according to the present invention, the stopper main body operates in conjunction with the switching shelf, thereby preventing the stopper from moving to the switching shelf by being locked to the object to be conveyed conveyed from the upstream conveying shelf. Can be switched between the locked state and the locked state where the transported object is moved to the switching shelf by releasing the locked state, so that no special electrical equipment is required, In the locked state, the horizontal bar of the stopper main body is locked to the conveyed object, so that the movement of the conveyed object to the switching shelf can be reliably prevented.

  Further, in the distribution shelf device according to the present invention, the stopper main body is formed in a portal shape by passing and connecting between the vicinity of the upper ends of the two vertical struts in which the horizontal bars are arranged at appropriate intervals. When the stopper is in the locked state, the horizontal bar is locked to the transported object transported from the upstream transport shelf and is prevented from moving to the switching shelf. In this case, the stopper main body may be lifted to release the locked state, and the conveyed object may pass under the horizontal bar and move to the switching shelf.

  Further, in the distribution shelf device according to the present invention, the stopper main body is provided with two parallel rods extending in the horizontal direction at appropriate intervals in the vertical direction with the vertical column as a base end on each of the two vertical columns. The switching shelf is provided with a working rod fixed to the switching shelf and projecting in the left-right direction of the switching shelf and extending in the horizontal direction. At least a part of the working rod is between the two parallel rods. The stopper main body can also be moved up and down in conjunction with the vertical movement of the switching shelf about the shelf support shaft. In this way, when the switching shelf moves up and down, the action rod moves up and down in the same manner, whereby the parallel rod is pushed up and down and the stopper body moves up and down. At this time, the working rod is arranged between the two parallel rods and presses the two parallel rods up and down in conjunction with the vertical movement of the switching shelf. Therefore, this working rod can be simply moved up and down without rotating in accordance with the rotating motion of the switching shelf.

Further, the distribution shelves apparatus according to the present invention, a receiving posture switching shelf, so comprises switching means for switching to a transport position, certainly it is possible to switch the operation and control of the receiving position and the conveying position.

  Further, in the physical distribution shelf device according to the present invention, the switching means can be switched manually or steppingly. In this way, it is not necessary to use a power source that operates with electric power, which contributes to energy saving.

  As described above, according to the physical distribution shelf device according to the present invention, the stopper main body operates in conjunction with the switching shelf, thereby locking the object to be conveyed conveyed from the upstream conveying shelf to the switching shelf. Since it is possible to switch between a locked state that prevents movement and a locked released state in which the transferred state is released and the conveyed object moves to the switching shelf, no special electrical equipment is required. In addition, in the locked state, the horizontal bar of the stopper main body is locked to the object to be conveyed, so that the movement of the object to be conveyed to the switching shelf can be reliably prevented.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an embodiment of a distribution shelf device according to the present invention. The distribution shelf device 1 is provided on the transport shelf main body 2 on the upstream side transport shelf 3 and below the upstream side transport shelf 3 and in a direction opposite to the transport direction of the upstream side transport shelf 3 (Y in FIG. 1). A downstream side transport shelf 4 that transports the transported object W in the opposite direction in the axial direction) and a switching shelf 5 that receives the transported object W from the upstream side transport shelf 3 and sends it to the downstream side transport shelf 4. It is. The switching shelf 5 is configured to receive the transported object W from the upstream transport shelf 3 (the state shown in FIGS. 2 and 3), and to send out the received transported object W to the downstream transport shelf 4 (see FIG. 2). 5), the operation can be switched by the operator's operation (note that the operator's operation is not particularly limited, but is a stepping operation in this embodiment). With this configuration, the physical distribution shelf device 1 holds the transported object W received from the upstream transport shelf 3 with the switching shelf 5 being in the receiving posture, while the worker holds the transported object W ( For example, an electrical part is taken out from a box, a container, etc., and the switching shelf 5 is switched from the receiving posture to the sending posture by the operator performing a switching operation after the work is finished, and is placed on the switching shelf 5. The placed object W is sent out from the switching shelf 5 to the downstream side transport shelf 4.

  The conveyance shelf main body 2 is mainly configured by a plurality of pipe members 21 to 23 and a joint member 24 that connects the pipe members. More specifically, the transport shelf body 2 includes a base frame 21 at the lower end formed in a substantially rectangular shape in plan view, a plurality of support members 22 rising upward from the base frame 21, and a lateral connection connecting the support members. It is an assembly formed by the crosspiece member 23 and the like. In addition, casters 25 are respectively provided below the four corners of the base frame body 21 so that the distribution shelf device 1 can be easily moved.

  The upstream-side transport shelf 3 and the downstream-side transport shelf 4 are respectively fixed at predetermined positions on the transport shelf body 2 so as to be inclined at a predetermined angle (of course, the predetermined position and angle are determined by the respective members). It can be changed arbitrarily by rearrangement). As shown in FIG. 1, in this embodiment, the upstream side transport shelf 3 is arranged so as to incline downward in the direction of the switching shelf 5 from the innermost portion in the Y-axis direction of the transport shelf body 2 and the vicinity of the upper end. It is installed. Further, the downstream side transport shelf 4 is inclined downward from the position where the transported object W can be received from the switching shelf 5 at the delivery position toward the innermost part in the Y-axis direction of the transport shelf body 2 and the vicinity of the lower end part. It is arranged in this way.

  In this embodiment, the upstream side transport shelf 3 and the downstream side transport shelf 4 are each composed of two rail members 31 and 41 arranged mainly in parallel. On the upper surface side (conveying surface), a plurality of rotating rollers 311 and 411 are arranged along the length direction of the rail members 31 and 41 (conveying direction of the article to be conveyed W). By being configured in this way, the transported object W placed on the transport surface of the upstream transport shelf 3 or the downstream transport shelf 4 has the upstream transport shelf 3 due to its own weight and the rotation of the rotation rollers 311 and 411. Or it moves so that the upper surface (conveyance surface) of the downstream conveyance shelf 4 may go down along the conveyance direction.

  Since the upstream side transport shelf 3 and the downstream side transport shelf 4 are inclined downward in the transport direction of the transported object W, the transported object W is not affected by its own weight even without the rotating roller members 311 and 411. Although it is conveyed so that it may slide on the upstream conveyance shelf 3 and the downstream conveyance shelf 4, in order to make conveyance more reliable and smooth, it is preferable to arrange | position the rotation rollers 311 and 411 as mentioned above. In addition, two rail members 31 and 41 are arranged for each of the upstream conveyance shelf 3 and the downstream conveyance shelf 4, but the number of rail members 31 and 41 is not limited to two, and three or more are arranged. Alternatively, the upstream-side transport shelf 3 or the downstream-side transport shelf 4 may be formed using a wide rail member, a single plate-like member, or the like.

  The switching shelf 5 is formed by forming a transport surface mainly by a plurality of pipe members 51 and a joint member 52 that connects the pipe members 51 to each other. In addition, the switching shelf 5 is located at a position farthest from the upstream side transport shelf 3 and the downstream side transport shelf 4 (the horizontal pipe member 51a at the position) and the side of the transport shelf body 2 via the two joints 53. It is connected to the crosspiece member 27. The horizontal pipe member 51a is inserted into the joint 53 in a loosely fitted state and can be rotated around its axis. As a result, the switching shelf 5 is rotatable about the horizontal pipe member 51a as a rotation axis, and can be switched between the receiving posture and the sending posture. In this embodiment, the switching shelf 5 is different from the upstream transport shelf 3 or the downstream transport shelf 4 described above, and does not use a rail member having a rotating roller, but the upstream transport shelf 3 or the downstream side. Similarly to the transport shelf 4, a rail member provided with a rotation roller may be used and disposed on the transport surface of the switching shelf 5.

  The switching shelf 5 is maintained at a predetermined position and angle by the support mechanism 6. In this embodiment, the support mechanism 6 is connected to the switching shelf 5 and supports the switching shelf 5 from below, and a support rod member 61 that can be bent. Is maintained in a straight line (not bent) (the switching shelf 5 is maintained in the receiving posture), and the support rod member 61 is bent by the operator's operation (this switches the switching shelf 5 to the sending posture). Action means 62 (hydraulic damper 62 in this embodiment) acting on the foot, and a foot rod 63 that causes the action means (hydraulic damper) 62 to act by the operator performing a stepping operation to bend the support rod member 61. It has. The support rod 61, the hydraulic damper 62, and the foot rod 63 are connected via a plurality of pipe members and joint members. Further, as shown in FIG. 1, the foot pedal 63 is operated by an operator stepping on the foot F.

  More specifically, the switching shelf 5 is supported by the support mechanism 6 as described above, and is in the receiving posture in a state where the operator does not operate anything. That is, the support mechanism 6 includes a support rod member 61 that supports the switching shelf 5 from below and can be bent at an intermediate portion thereof, and the hydraulic damper 62 is connected to the support rod member 61 via the pipe member 64. When the operator does not perform any operation, the hydraulic damper 62 is extended to maintain the support rod member 61 in a straight line (in a non-bent state). The shelf 5 is maintained in the receiving posture (state shown in FIG. 2).

  Further, when the operator steps on the foot rod 63 with his foot F, the force applied to the foot rod 63 causes the hydraulic damper 62 to move through the support rod (pipe member) 64 connected to the foot rod 63. The support rod member 61 is bent while contracting against the force to be extended, and thereby the switching shelf 5 is pulled down to be in the delivery posture (state of FIG. 5).

  The support mechanism 6 is not limited to the above-described form, and any form of mechanism can be used as long as the switching shelf 5 can be switched between the receiving position and the sending position by a simple operation by the operator. But you can choose and use them arbitrarily. For example, in the present embodiment, the support rod member 61 is configured to bend the switching shelf 5 from the receiving posture to the sending posture by being bent. However, the support rod member 61 is not limited to this, and a telescopic support rod member 61 can also be used. It is. Also, the action means 61 uses the hydraulic damper 62 in this embodiment, but is not limited to this, and various shock absorbers, elastic bodies (spring bodies), or the support rod members 61 as well as these are linear. Any means that can be maintained and bent can be used.

  The switching shelf 5 in the receiving position has an upper surface (transport surface) closest to the upstream transport shelf 3 on the extension line of the upper surface (transport surface) of the upstream transport shelf 3 or a position slightly lower than the extension line. As a result, the article W to be transported from the upstream transport shelf 3 is smoothly transported onto the switching shelf 5. Further, the switching shelf 5 in the delivery posture is inclined downward toward the downstream side transport shelf 4, and the upper surface (transport surface) closest to the downstream side transport shelf 4 is the upper surface of the downstream side transport shelf 4. It is made to become the position on the extension line of (conveyance surface) or slightly higher than the extension line. As a result, when the switching shelf 5 is switched from the receiving posture to the sending posture, the article W to be transported placed on the switching shelf 5 is smoothly sent onto the downstream conveying shelf 4.

  Further, in the distribution shelf device 1, a stopper 7 is provided for temporarily restricting the movement of the transported object W transported from the upstream transport shelf 3. As shown in FIGS. 3 to 5, in this stopper, the switching shelf 5 operates from the receiving posture to be in the sending posture, and sends the previous conveyed object W <b> 1 to the downstream conveying shelf 4, and then returns to the receiving posture. This is for restricting the subsequent transported object W <b> 2 from moving to the switching shelf 5.

  When the switching shelf 5 is in the receiving posture and the preceding transported object W1 is on the switching shelf 5, as shown in FIG. 3, the rear end face of the preceding transported object W1 (conveyance of the transported object W) The rear end face in the direction is in contact with the front end portion of the subsequent transported object W2, thereby restricting the movement of the subsequent transported object W2 to the switching shelf 5 (usually in this state, the work The person carries out the work of taking out the parts and the like stored in the previous transported object W1). Further, when the previous transported object W1 is sent to the downstream transport shelf 4 and the switching shelf 5 returns to the original receiving posture (that is, the switching shelf 5 is in the receiving posture, and the previous transported material W1 is switched). When it is not on the shelf 5), the succeeding article W <b> 2 moves to the switching shelf 5 after the restriction by the stopper 7 is released. Although not shown, if there is a further subsequent transported object W3 on the upstream transport shelf 3, the front end of the transported object W3 is connected to the rear end surface of the transported object W2 (the transport of the transported object W2). The rear end face in the direction), thereby restricting the movement of the conveyed object W3 to the switching shelf 5.

  The stopper 7 moves up and down in conjunction with the operation (vertical movement) of the switching shelf 5 as will be described later, thereby restricting the movement of the article W to be transported from the upstream conveyance shelf 3 to the switching shelf 5 as described above. In addition, the restriction is released and the conveyed object W can be moved to the switching shelf 5.

  The stopper 7 is a gate composed of a horizontal bar 711 that comes into contact with the object to be conveyed W and restricts its movement, and two vertical columns 712 and 712 that are connected to the vicinity of both ends of the horizontal bar 711 and extend substantially vertically downward. A mold stopper body 71 is provided. The two vertical struts 712 of the stopper main body 71 are inserted into holding joints 28 fixed to the transport shelf main body 2, respectively. That is, the holding joint 28 is formed with a cylindrical insertion hole 281 that is opened in the vertical direction and inserted therethrough (see FIG. 2), and the vertical column 712 is inserted into the insertion hole 281. The inner diameter of the insertion hole 281 is slightly larger than the outer diameter of the vertical column 712. The insertion hole 281 has a predetermined height dimension. By providing the above-described configuration, the two vertical struts 712 are attached to the transport shelf body 2 so as to be freely movable in the vertical direction in the insertion hole 281, and in the front-rear left-right direction (horizontal The movement of the vertical support column 712 is prevented from wobbling in the horizontal direction. Therefore, the stopper main body 71 can freely move up and down without wobbling. The stopper main body 71 is disposed in the vicinity of the boundary between the upstream transport shelf 3 and the switching shelf 5, and the horizontal bar 711 is disposed so as to cross the transport direction of the object W to be transported. ing. Further, even when the movement of the transported object W from the upstream transport shelf 3 to the switching shelf 5 is restricted, the restriction can be removed and the transported object W can move from the upstream transport shelf 3 to the switching shelf 5. Even in this state, the horizontal bar 711 is arranged to be positioned above the respective conveyance surfaces (upper surfaces) of the upstream conveyance shelf 3 and the switching shelf 5.

  In addition, two horizontal rods 73 (an upper horizontal rod 731 and a lower horizontal rod 732) extending in a substantially horizontal direction from the vertical column 712 are provided in the vicinity of the lower end portion of each vertical column 712. The upper horizontal ridge 731 and the lower horizontal ridge 732 are arranged at a predetermined interval so as to enter an interval (gap 74) formed between the upper horizontal ridge 731 and the lower horizontal ridge 732. A working rod 55 fixed to the switching shelf 5 is arranged.

  The working rod 55 is a pipe member that extends in the left-right direction and substantially in the horizontal direction across the transport direction of the distribution shelf device 1, is fixed to the lower surface of the switching shelf 5, and is longer than the width dimension of the switching shelf 5, It is supposed to protrude in the direction. As described above, the vicinity of the tip of the working rod 55 is arranged so as to enter the gap 74 formed between the upper horizontal rod 731 and the lower horizontal rod 732. It is not fixed or connected to any of the horizontal rod 731, the lower horizontal rod 732, or the vertical column 712. The upper horizontal rod 731 and the lower horizontal rod 732 each have a predetermined length, and the vertical height of the gap 74 is larger than the outer diameter of the working rod 55, so that the operator can perform any operation. In the state where it is not, the stopper 7 is held at a predetermined height such that the upper end surface of the working rod 55 is placed on the lower end surface of the upper horizontal rod 731. At this time, the horizontal bar 711 of the stopper 7 is at the highest position, and the article to be transported W can move under the horizontal bar 711. At this time, as described above, the preceding transported object W1 placed on the upstream side shelf device 3 moves to the switching shelf 5, and the subsequent transported object W2 has its front end positioned at the previous transported object. It is made to come into contact with the rear end surface of the transported object W1 (the rear end surface in the transport direction of the transported object W), thereby restricting the movement of the subsequent transported object W2 to the switching shelf 5 (usually in this state, The operator performs an operation of taking out the parts and the like stored in the previous transported object W1).

  When the worker finishes taking out the parts and the like stored in the previous article to be conveyed W1, the operator steps on the foot pedal 63 to move the article to be conveyed W1 from the switching shelf 5 to the downstream conveyance shelf 4. Further, the subsequent transported object W2 is moved from the upstream transport shelf 3 to the switching shelf 5. This operation will be described in detail. First, when the operator steps on the foot pedal 63 and the switching shelf 5 moves from the receiving posture to the sending posture (downward), the stopper 7 also moves downward in conjunction with this. That is, with the operation of the switching shelf 5, the working rod 55 is lowered downward, and the lower end surface of the working rod 55 pushes down the upper end surface of the lower horizontal rod 732, so that the stopper 7 is lowered downward (or the upper horizontal rod). When the working rod 55 that supports the lower end surface of 731 is lowered downward, the stopper 7 is lowered downward by its own weight).

  Thereby, the switching shelf 5 and the stopper 7 are changed from the state shown in FIG. 3 (receiving posture) to the state shown in FIG. 5 (sending posture) through the state shown in FIG. In this sending posture, the previous article W1 is sent out to the downstream side transport shelf 4. Further, the horizontal bar 711 of the stopper 7 is at a position higher than the transport surface of the upstream transport shelf 3 and lower than the upper end of the transported object W, whereby the horizontal bar 711 is moved to the subsequent transported object. It contacts the front end surface of W2 and regulates the movement of the conveyed object W2.

  Then, when the operator removes the foot F from the foot pedal 63, the switching shelf 5 moves from the sending posture (state of FIG. 5) to the receiving posture (state of FIG. 3) through the state of FIG. That is, when the operator removes his / her foot from the foot rod 63, the hydraulic damper 62 extends and returns to the original state, and the switching shelf 5 moves upward to be in the receiving posture, and acts together with the operation of the switching shelf 5. The collar 55 rises upward, the upper end surface of the working collar 55 pushes up the lower end surface of the upper horizontal collar 731, and the stopper 7 also returns to the original position, that is, the highest position.

  In this state, the horizontal bar 711 of the stopper 7 is positioned above the upper end of the subsequent transported object W2, so that the transported object W2 released from the restriction by the horizontal bar 711 is switched. Move to the shelf 5 (note that although not shown, further subsequent objects to be conveyed W3, W4, W5,... Are sequentially placed on the conveyance surface of the upstream shelf device 3 by the operator's stepping operation, Repeat the same operation).

  As described above, the action rod 55 is arranged so as to enter the gap 74 formed between the upper horizontal rod 731 and the lower horizontal rod 732, but the upper horizontal rod 731 and the lower horizontal rod 732 are arranged. Or it is not fixed or connected to any of the vertical columns 712. Therefore, as shown in the side views of FIGS. 3 to 5, the switching rack 5 and the working rod 55 fixed to the switching rack by switching between the receiving attitude and the sending attitude are arcuate around the horizontal pipe member 51 a as the rotation axis. Although it moves downward (or upward) as depicted, the stopper 7 is interlocked with the operation of the switching shelf 5 and the action rod 55, but can be operated only in the vertical direction regardless of the arc-shaped operation. ing. Therefore, since unnecessary force does not act on the stopper 7, the risk of damage to the stopper 7 is small.

  Moreover, the inclination angle of the conveyance surface of the switching shelf 5 is made larger than the inclination angle of the upstream conveyance shelf 3 in the receiving posture. Then, as shown in FIG. 3, if the inclination of the preceding conveyed object W1 on the switching shelf 5 and the inclination of the subsequent conveyed object W2 on the upstream conveying shelf 3 are compared, The inclination of the object to be conveyed W2 is larger than the inclination of the object to be conveyed W2. Accordingly, at this time, the rear end surface of the preceding transported object W1 (the rear end surface in the transporting direction of the transported object W) and the front end of the subsequent transported object W2 are in contact with each other in the vicinity of the lower end thereof, but the upper end thereof There is a gap M between the parts. With such a configuration, when the switching shelf 5 is moved from the receiving posture to the sending posture, the horizontal bar of the stopper 7 can easily enter the gap, and the subsequent transported object W2 moves to the switching shelf 5. Can be suitably controlled.

  In addition, the dimension of each member of the shelf apparatus 1 for physical distribution which concerns on this invention including the conveyance shelf main body 2 can be changed arbitrarily. In this distribution shelf device 1, many members are composed of a pipe member and a joint member that connects the pipe members. Therefore, the length of the pipe member is appropriately adjusted, and the pipe having the optimum length is also provided. By using the members, the distribution shelf device 1 having any size can be configured according to the size of the transported object W, the distance to which the transported object should be transported, and the like.

  As described above, the physical distribution shelf device 1 according to the present invention has been described by showing a specific embodiment, but the present invention is not limited to the above-described embodiment, and does not depart from the spirit of the present invention. It is possible to change the form and the like in various ways. That is, the embodiment disclosed this time is illustrative in all respects, and does not serve as a basis for limited interpretation. Therefore, the technical scope of the present invention is not construed only by the above-described embodiments, but is defined based on the description of the scope of claims, and is within the meaning and scope equivalent to the scope of claims. All changes are included.
